Background: Cerebrospinal fluid (CSF) and spinal MRIs are often obtained in children with the radiologically isolated syndrome (RIS) for diagnosis and prognosis. Factors affecting the frequency and timing of these tests are unknown. Objective: To determine whether age or sex were associated with (1) having CSF or spinal MRI obtained or (2) the timing of these tests. Methods: We analyzed children (≤ 18 y) with RIS enrolled in an international longitudinal study. Index scans met 2010/2017 multiple sclerosis (MS) MRI criteria for dissemination in space (DIS). We used Fisher's exact test and multivariable logistic regression (covariates = age, sex, MRI date, MRI indication, 2005 MRI DIS criteria met, and race). Results: We included 103 children with RIS (67% girls, median age = 14.9 y). Children ≥ 12 y were more likely than children < 12 y to have CSF obtained (58% vs. 21%, adjusted odds ratio [AOR] = 4.9, p = 0.03). Pre-2017, girls were more likely than boys to have CSF obtained (n = 70, 79% vs. 52%, AOR = 4.6, p = 0.01), but not more recently (n = 30, 75% vs. 80%, AOR = 0.2, p = 0.1; p = 0.004 for interaction). Spinal MRIs were obtained sooner in children ≥ 12 y (median 11d vs. 159d, p = 0.03). Conclusions: Younger children with RIS may be at continued risk for misdiagnosis and misclassification of MS risk. Consensus guidelines are needed. [ABSTRACT FROM AUTHOR]

Background: Paid parental leave policies may promote breastfeeding, which can have short- and long-term health benefits for both members of the birthing person-infant dyad. In the United States, where 56% of the workforce qualifies for unpaid federal medical leave, certain states have recently enacted paid parental and family leave policies. We aimed to assess the extent to which living in states with versus without paid family leave was associated with feeding regimens that included breastfeeding. Methods: In this cross-sectional analysis of the 2021 National Immunization Survey-Child, we assessed feeding outcomes: (1) exclusively breastfed (only fed breastmilk—never infant formula—both before and after six months of age), (2) late mixed breastfeeding (formula after six months), (3) early mixed breastfeeding (breastfed, formula before six months), and (4) never breastfed. We conducted Pearson χ2 to compare social-demographic characteristics and multivariable nominal regression to assess extent to paid family leave was associated with breastfeeding regimens, compared with never breastfeeding. Results: Of the 35,995 respondents, 5,806 (25% of weighted respondents) were from states with paid family leave policies. Compared with never breastfeeding, all feeding that incorporated breastfeeding—exclusive breastfeeding, late mixed feeding (breastfed, formula introduced after six months), and early mixed feeding (breastfed, formula introduced before six months)—were more prevalent in states with paid family leave policies. The adjusted prevalence ratio (aPR) and differences in adjusted prevalence compared with never breastfeeding in states with versus without paid family leave policies were: aPR 1.41 (95% CI 1.15, 1.73), 5.36% difference for exclusive breastfeeding; aPR 1.25 (95% CI 1.01, 1.53), 3.19% difference for late mixed feeding, aPR 1.32 (95% CI 1.32, 1.97), 5.42% difference for early mixed feeding. Conclusion: States with paid family leave policies have higher rates of any breastfeeding and of exclusive breastfeeding than states without such policies. Because all feeding types that incorporate breastfeeding were higher in states with paid family leave policies, expansion of paid family leave may improve breastfeeding rates. [ABSTRACT FROM AUTHOR]

Background: Although AIDS-related deaths have reduced with increased access to antiretroviral care, cardiovascular disease-related morbidities among persons living with HIV are rising. Contributing to this is the higher incidence of Hypertension among Persons Living with HIV. The duration of exposure to the virus and antiretroviral drugs plays a vital role in the pathogenesis, putting perinatally infected children and adolescents at higher risk than behaviorally-infected ones, supporting the calls for increased surveillance of Hypertension among them. Despite the availability of guidelines to support this surveillance, the blood pressure (BP) of adolescents living with HIV (ADLHIV) is not checked during clinical visits. This study aims to assess the effect of a theory-based intervention on healthcare workers' adherence to the guidelines for hypertension screening among adolescents. Methods: A multi-facility cluster-randomized study will be conducted. The clusters will be 20 antiretroviral therapy sites in the Greater Accra Region of Ghana with the highest adolescent caseload. Data will be extracted from the folders of adolescents (10–17 years) who received care in these facilities six months before the study. The ART staff of intervention facilities will receive a multicomponent theory of planned behaviour-based intervention. This will include orientation on hypertension risk among ADLHIV, provision of job aids and pediatric sphygmomanometers. Six months after the intervention, the outcome measure will be the change from baseline in the proportion of ADLHIV whose BP was checked during clinical visits. The calculated sample size is 400 folders. Implications of findings: This study will generate evidence on the effectiveness of a multicomponent theory-based intervention for improving the implementation of clinical practice guidelines.

Background: Antiretroviral therapy (ART)‐associated metabolic abnormalities, including impairment of glucose metabolism, are prevalent in adults living with HIV. However, the prevalence and pathogenesis of impaired glucose metabolism in children and adolescents living with HIV, particularly in sub‐Saharan Africa, are not well characterized. We investigated the prevalence of impaired glucose metabolism among children and adolescents living with perinatally infected HIV in Ghana. Methods: In this multicentre, cross‐sectional study, we recruited participants from 10 paediatric antiretroviral treatment clinics from January to June 2022 in 10 facilities in Greater Accra and Eastern regions of Ghana. We determined impaired glucose metabolism in the study sample by assessing fasting blood sugar (FBS), insulin resistance as defined by the homeostatic model assessment for insulin resistance (HOMA‐IR) index and glycated haemoglobin (HbA1c) levels. The prevalence of impaired glucose metabolism using each criterion was stratified by age and sex. The phenotypic correlates of glucose metabolism markers were also assessed among age, sex, body mass index (BMI) and waist‐to‐hip ratio (WHR). Results: We analysed data from 393 children and adolescents living with HIV aged 6–18 years. A little over half (205/393 or 52.25%) of the children were female. The mean age of the participants was 11.60 years (SD = 3.50), with 122/393 (31.00%) aged 6–9 years, 207/393 (52.67%) aged 10–15 years, and 62/393 (15.78%) aged 16–18 years. The prevalence rates of glucose impairment in the study population were 15.52% [95% confidence interval (CI): 12.26–19.45], 22.39% (95% CI: 18.54–26.78), and 26.21% (95% CI: 22.10–30.78) using HbA1c, HOMA‐IR, and FBS criteria, respectively. Impaired glucose metabolism detected by FBS and HOMA‐IR was higher in the older age group, whereas the prevalence of abnormal HbA1c levels was highest among the youngest age group. Age and BMI were positively associated with FBS and HOMA‐IR (p < 0.001). However, there was negative correlation of WHR with HOMA‐IR (p < 0.01) and HbA1c (p = 0.01). Conclusion: The high prevalence of impaired glucose metabolism observed among the children and adolescents living with HIV in sub‐Saharan Africa is of concern as this could contribute to the development of metabolic syndrome in adulthood.

Objective: The objective of this study was to examine the association between rate of gestational weight gain (GWG) and preterm birth (PTB) classified by pre‐pregnancy BMI among Pacific Islander individuals in the United States. Methods: Pacific Islander mothers (n = 55,975) and singleton infants (22–41 gestational weeks) without congenital anomalies were included using data from the National Center for Health Statistics (2014–2018). PTB was compared by pre‐pregnancy BMI among women in each stratum of rate of GWG using Cox proportional hazards models. Results: Compared with mothers with a rate of GWG within the guidelines, mothers with a rate of GWG below the guidelines and either pre‐pregnancy underweight (adjusted hazard ratio [aHR] = 1.84, 95% CI: 1.10–3.06), healthy weight (aHR = 1.38, 95% CI: 1.15–1.65), obesity class I (aHR = 1.22, 95% CI: 0.97–1.52), or obesity class II (aHR = 1.43, 95% CI: 1.05–1.96) had an increased risk of PTB; mothers with a rate of GWG above the guidelines and either pre‐pregnancy underweight (aHR = 1.57, 95% CI: 0.92–2.69) or obesity class II (aHR = 1.31, 95% CI: 0.98–1.76) had an increased risk of PTB. Conclusions: The association between rate of GWG below or above the guidelines and PTB differs by pre‐pregnancy BMI among Pacific Islander individuals. [ABSTRACT FROM AUTHOR]

Background: Antiretroviral therapy‐associated adverse effects and comorbidities are still pervasive in people living with HIV, especially metabolic syndrome (MetS). We investigated the age‐dependent prevalence of components of MetS and insulin resistance in children and adolescents living with HIV (CALWH). Methods: A cross‐sectional pilot study of CALWH treated at the Baylor Uganda Clinical Centre of Excellence in Kampala, Uganda, May to August 2021. The primary outcome of MetS was defined by both the International Diabetes Federation (IDF) and the Adult Treatment Panel (ATP III) criteria. We estimated the prevalence of MetS and its components for all participants and by the stratification factors. Results: We enrolled 90 children and adolescents, aged 6 to <10 years (n = 30), 10 to <16 years (n = 30), and ≥ 16 to <19 years (n = 30). Fifty‐one percent were females. The estimated prevalence of MetS was 1.11% (1 of 90) using either IDF or ATPIII criteria for all participants, and 3.33% in the oldest age group. Notably, while only one among study participants met the criterion based on having central obesity or blood pressure, over 55% of participants had one or more IDF component, with 47% having low high‐density lipoprotein (HDL) cholesterol. Two participants (6.67%) in the group aged 10 to <16 years met one of the definitions for insulin resistance (IR) using the Homeostatic Model Assessment (HOMA‐IR) index. For every 1‐year increase in age, HOMA‐IR index increased by 0.04 (95% confidence interval: 0.01–0.08; p = 0.02). Conclusions: With increasing survival of CALWH into adulthood, lifetime exposure to ART, the frequency of MetS in this population may rise, increasing the lifetime risk for associated health problems. There is a need to study the natural history of MetS in CALWH to inform preventative and treatment interventions as needed. [ABSTRACT FROM AUTHOR]

Background: In youth with type 1 diabetes (T1D), high haemoglobin A1c (HbA1c) levels are associated with an increased risk for diabetic ketoacidosis (DKA). Aims: This study examined whether daily school‐supervised basal insulin injections were feasible and if they reduced the risk of morning ketosis in children and adolescents with high HbA1c levels. We hypothesized that supervised glargine and degludec would reduce the risk of ketosis and that the prolonged action of degludec would protect from ketosis after consecutive days of unsupervised injections. Materials & Methods: After a 2–4‐week run‐in, youth (10–18 years, HbA1c ≥ 8.5%) managing T1D with injections were randomized to school‐supervised administration of degludec or glargine for 4 months. School nurses observed daily blood β‐hydroxybutyrate (BHB) and glucose checks. During COVID closures, the research team supervised procedures remotely. Results: Data from 28 youth (age 14.3 ± 2.3 years, HbA1c 11.4 ± 1.9%, 64% F) were analysed. School‐supervised injections of both basal insulins for 1–4 days progressively lowered the percent of participants with elevated BHB. The percent of participants with elevated BHB (≥0.6 mmol/L) after 2 days of unsupervised basal insulin doses at home was greater in the glargine than degludec group but had a high p‐value (17.2% vs. 9.0%, p = 0.3). HbA1c was unchanged in both groups. Discussion: In youth with T1D at high risk for DKA, daily supervised long‐acting insulin administration decreased the probability of elevated ketone levels on subsequent school days, regardless of basal insulin type. A larger sample size may have demonstrated that the longer action profile of degludec would offer additional protection from ketosis during days of not attending school. Conclusion: Engaging school‐based caregivers in management of youth with T1D on injected insulin may decrease clinically significant ketosis and minimize acute complications of diabetes.

Until recently, the question of the methodological role in the professional activity of a teacher, depending on the peculiarities of the performed functions, has remained unexplored. Also, a number of urgent problems have not been fully studied. What is the actual connection between teaching methodology and methodology? What is the influence of methodology on teaching methodology? How can methodology help teachers while implementing their multifunctional professional tasks? This study can be divided into several stages: identification of the connection between the general methodology of teaching foreign languages and methodology (the first stage of the research); clarification of the main directions of the methodological function implementation of the theory of teaching foreign languages (second stage of the research); specifying the conditions of the successful implementation of the methodological function of teaching foreign languages theory (third stage of the research). The study not only reveals the connections between teaching methodology with methodology, but also identifies the prospects for the development of methodological thought in relation to the professional training of foreign language teachers. This prospect is closely related to the methodological function of teaching methodology. The implementation of the present function is aimed at the research, reconstruction and description of certain methods and value-based objects of language education as well as methodological reflection of scientific research conducted within the framework of the given study and the educational activity. The consideration of the teaching methodology from the point of view of methodology allows us to reveal the content and direction of the methodological function realisation within the given science as well as to provide arguments for the significance of its inclusion into the scientific vocabulary of such categories as ‘methodological consciousness’ and ‘methodological culture’.

Objective: Nonalcoholic fatty liver disease (NAFLD), the most common liver disease among youth with obesity, precedes more severe metabolic and liver diseases. However, the impact of the Sars‐CoV‐2 global pandemic on the prevalence and severity of NAFLD and the associated metabolic phenotype among youth with obesity is unknown. Methods: Participants were recruited from the Yale Pediatric Obesity Clinic during the Sars‐CoV‐2 global pandemic (August 2020 to May 2022) and were compared with a frequency‐matched control group of youth with obesity studied before the Sars‐CoV‐2 global pandemic (January 2017 to November 2019). Glucose metabolism differences were assessed during an extended 180‐minute oral glucose tolerance test. Magnetic resonance imaging‐derived proton density fat fraction (PDFF) was used to determine intrahepatic fat content in those with NAFLD (PDFF ≥ 5.5). Results: NAFLD prevalence increased in participants prior to (36.2%) versus during the Sars‐CoV‐2 pandemic (60.9%), with higher PDFF values observed in participants with NAFLD (PDFF ≥ 5.5%) during versus before the pandemic. An increase in visceral adipose tissue and a hyperresponsiveness in insulin secretion during the oral glucose tolerance test were also observed. Conclusions: Hepatic health differences were likely exacerbated by environmental and behavioral changes associated with the pandemic, which are critically important for clinicians to consider when engaging in patient care to help minimize the future risk for metabolic perturbations.

Objective Exposure to diabetes mellitus during pregnancy increases the risk of offspring obesity and cardiometabolic disease. Limited information exists regarding growth patterns among preterm infants exposed to maternal diabetes. This study describes growth differences during early childhood among late preterm infants of mothers with and without diabetes during pregnancy. Materials and methods In a retrospective longitudinal analysis, weight trajectories from birth to age 2 years were compared between diabetes exposure groups (N = 1554) using mixed effects modeling and adjusting for maternal and infant demographic covariates. Results Overall, 134 (9%) infants were exposed to diabetes (DM-group). DM-group had higher average weight (adjusted difference 300 g [95% CI: 228, 371]) and weight z-score (adjusted difference 0.67 standard deviation scores (SDS) [95% CI: 0.50, 0.84]) compared with unexposed infants. DM-group infants had accelerated weight gain from birth to discharge (adjusted weight difference 31.8 g [95% CI: 12.5, 51.1], adjusted weight z-score difference 0.07 SDS [95% CI: 0.02, 0.11]) compared with unexposed infants, including in the first postnatal week (adjusted weight gain velocity difference, day 0–3: 6.07 g/day [95% CI: 0.88, 11.25]; day 3–7: 8.37 g/day [95% CI: 1.60, 15.13]). Through age two, infants in the DM-group maintained higher average weight (adjusted difference 185.7 g [95% CI: 37.2, 334.3]) and weight z-score (adjusted difference 0.32 SDS [95% CI: 0.09, 0.55]) than unexposed infants, with greater weight gain between 18 and 24 months (adjusted difference 28.5 g/week [95% CI: 2.6, 54.4]). Conclusions Maternal diabetes exposed late preterm infants had higher weight from birth to age two and greater weight gain in the first postnatal week than unexposed infants. Long term risk associated with weight trajectories in this population requires further study. [ABSTRACT FROM AUTHOR]

Background: This paper discusses question? associated with the conceptual components and val-ue targets of modern professional linguistic education in Russia. The essence of two concepts, i.e. "linguistic education" and "content" in relation to their multidi- mensionality and the systemic nature of each of them is noted. Purpose: The purpose of this research is to conceptualize the specificity of modern professional linguistic education in Russia and highlight the axi- ological potential and value-based meanings reflected in its content. Design/methodology/approach: The study is based on the theoretical ideas of the axiological learner-centered and activity-based approaches. Meth-odologically it is supported by the critical analysis generalization, classification and pedagogical observation. Findings: Particular attention is paid to theii axiological (value-oriented) aspects related to moral and spiritual establishment of students learning a foreign language and culture of its bearer people, as well as to the formation of a system of values- and meanings-based relations determining behavioral (verbal and non-verbal) models of specialists -- non-native speakers of the language -- in conditions of professional communication. It is argued that linguistic education is distinguished by its tiered nature according to two grounds: as the educational agency to which the content is addressed and as the level of designing. devising, and implementing the said content. Conclusions: In language training of specialists, one must target not only at their communicative sphere of personality, but at its values- and meanings-based, motivational, and cognitive components, too. Meanwhile, it is crucial to take into account students' feelings and emotions sphere of personality and their humanist values; it matters as much to have students develop a motivated attitude to innovation self-education and the ability to interact with communication partners in socially determined and professional situations in a productive non-confrontational way.

Introduction: Family-level psychosocial factors appear to play a critical role in mediating the intergenerational transmission of trauma; however, no review article has quantitatively synthesized causal mechanisms across a diversity of trauma types. This study aims to systematically consolidate the epidemiological research on family-level psychosocial mediators and moderators to ultimately produce causal diagram(s) of the intergenerational transmission of trauma. Methods: We will identify epidemiological peer-reviewed publications, dissertations, and conference abstracts that measure the impact of at least one psychosocial family-level factor mediating or moderating the relationship between parental trauma exposure and a child mental health outcome. English, French, Kinyarwanda, and Spanish articles will be eligible. We will search MEDLINE, PsycINFO, PTSDpubs, Scopus, and ProQuest Dissertations and Theses and will conduct forward citation chaining of included documents. Two reviewers will perform screening independently. We will extract reported mediators, moderators, and relevant study characteristics for included studies. Findings will be presented using narrative syntheses, descriptive analyses, mediation meta-analyses, moderating meta-analyses, and causal diagram(s), where possible. We will perform a risk of bias assessment and will assess for publication bias. Discussion: The development of evidence-based causal diagram(s) would provide more detailed understanding of the paths by which the psychological impacts of trauma can be transmitted intergenerationally at the family-level. This review could provide evidence to better support interventions that interrupt the cycle of intergenerational trauma.

Objective: In a large, multiethnic cohort of youths with obesity, we analyzed pathophysiological and genetic mechanisms underlying variations in plasma glucose responses to a 180 min oral glucose tolerance test (OGTT).Research Design and Methods: Latent class trajectory analysis was used to identify various glucose response profiles to a nine-point OGTT in 2,378 participants in the Yale Pathogenesis of Youth-Onset T2D study, of whom 1,190 had available TCF7L2 genotyping and 358 had multiple OGTTs over a 5 year follow-up. Insulin sensitivity, clearance, and β-cell function were estimated by glucose, insulin, and C-peptide modeling.Results: Four latent classes (1 to 4) were identified based on increasing areas under the curve for glucose. Participants in class 3 and 4 had the worst metabolic and genetic risk profiles, featuring impaired insulin sensitivity, clearance, and β-cell function. Model-predicted probability to be classified as class 1 and 4 increased across ages, while insulin sensitivity and clearance showed transient reductions and β-cell function progressively declined. Insulin sensitivity was the strongest determinant of class assignment at enrollment and of the longitudinal change from class 1 and 2 to higher classes. Transitions between classes 3 and 4 were explained only by changes in β-cell glucose sensitivity.Conclusions: We identified four glucose response classes in youths with obesity with different genetic risk profiles and progressive impairment in insulin kinetics and action. Insulin sensitivity was the main determinant in the transition between lower and higher glucose classes across ages. In contrast, transitions between the two worst glucose classes were driven only by β-cell glucose sensitivity. [ABSTRACT FROM AUTHOR]

Objectives: Opioid exposed infants born to incarcerated women represent a vulnerable and understudied subset of infants with neonatal abstinence syndrome (NAS). The impact of maternal incarceration on length of stay (LOS) for infants with NAS is unknown. We hypothesized that infants with NAS born to incarcerated women have longer hospitalizations compared to infants with NAS born to non-incarcerated women. Methods: This is a retrospective cohort study of infants with NAS born between 2011 and 2018 at the primary delivery site for Connecticut's only women's prison. Opioid exposed infants were assessed by Finnegan Scores for withdrawal and received morphine as a first line agent and phenobarbital as a second line agent. LOS was compared using Poisson regression. Results: Of 206 infants identified, 166 were included in the analysis, with 28 born to incarcerated women and 138 to non-incarcerated women. Incarcerated women were more likely to report prenatal alcohol use, 14.3% vs 2.2% p = 0.016 and benzodiazepine use 21.4% vs 7.3% p = 0.032. Infants of incarcerated women were less likely to be fed breast milk at discharge, 3.6% vs 37% p < 0.001. Adjusted mean LOS was longer among infants born to incarcerated women, 18.5 vs 16.6 days (p = 0.009). Conclusions for Practice: Infants with NAS born to incarcerated women in Connecticut had longer LOS, lower rates of being fed breast milk, and different prenatal substance exposures than infants with NAS born to non-incarcerated women. Supporting the maternal–infant dyad until infant discharge may mitigate the potential negative impact of maternal incarceration on the care of infants with NAS. [ABSTRACT FROM AUTHOR]

Multisystem inflammatory syndrome in children (MIS-C) is one of the most significant sequela of coronavirus disease 2019 (COVID-19) in children. Emerging literature has described myocardial dysfunction in MIS-C patients using traditional and two-dimensional speckle tracking echocardiography in the acute phase. However, data regarding persistence of subclinical myocardial injury after recovery is limited. We aimed to detect these changes with deformation imaging, hypothesizing that left ventricular global longitudinal (GLS) and circumferential strain (GCS) would remain impaired in the chronic phase despite normalization of ventricular function parameters assessed by two-dimensional echocardiography. A retrospective, single-institution review of 22 patients with MIS-C was performed. Fractional shortening, GLS, and GCS, along with regional longitudinal (RLS) and circumferential strain (RCS) were compared across the acute, subacute, and chronic timepoints (presentation, 14–42, and > 42 days, respectively). Mean GLS improved from − 18.4% in the acute phase to − 20.1% in the chronic phase (p = 0.4). Mean GCS improved from − 19.4% in the acute phase to − 23.5% in the chronic phase (p = 0.03). RCS and RLS were impaired in the acute phase and showed a trend towards recovery by the chronic phase, with the exception of the basal anterolateral segment. In our longitudinal study of MIS-C patients, GLS and GCS were lower in the acute phase, corroborating with left ventricular dysfunction by traditional measures. Additionally, as function globally recovers, GLS and GCS also normalize. However, some regional segments continue to have decreased strain values which may be an important subclinical marker for future adverse events. [ABSTRACT FROM AUTHOR]

Objective: This study investigated whether variations in cell death-inducing DNA fragmentation factor alpha subunit-like effector A (CIDEA) mRNA expression and protein levels are modulated by the pattern of abdominal fat distribution in adolescent girls with obesity. Methods: This study recruited 35 adolescent girls with obesity and characterized their abdominal fat distribution by magnetic resonance imaging. Participants had only a periumbilical/abdominal (n = 14) or a paired abdominal and gluteal subcutaneous adipose tissue (SAT) biopsy (n = 21). CIDEA expression was determined by reverse transcription-polymerase chain reaction, CIDEA protein level by Western blot, and the turnover of adipose lipids and adipocytes by 2H2O labeling. In six girls, a second abdominal SAT biopsy was performed (after ~34.2 months) to explore the weight gain effect on CIDEA expression in abdominal SAT. Results: CIDEA expression decreased in abdominal SAT from participants with high visceral adipose tissue (VAT)/(VAT+SAT); CIDEA inversely correlated with number of small adipocytes, with the increase in preadipocyte proliferation, and with adipogenesis. A strong inverse correlation was found between CIDEA protein level with the newly synthetized glycerol (r = -0.839, p = 0.0047). Following weight gain, an increase in adipocytes' cell diameter with a decrease in CIDEA expression and RNA-sequencing transcriptomic profile typical of adipocyte dysfunction was observed. Conclusions: Reduced expression of CIDEA in girls with high V AT/(VAT+SAT) is associated with adipocyte hypertrophy and insulin resistance. [ABSTRACT FROM AUTHOR]

Background: In the last few years, there has been a growing interest in the role of gut microbiota in the development of obesity and its complications.Objectives: In this study, we tested the following hypotheses: 1) lean youth and youth with obesity experience a different capability of their gut microbiota to ferment carbohydrates and produce acetate; and 2) colonic acetate may serve as a substrate for hepatic de novo lipogenesis (DNL).Methods: Nineteen lean youth [mean ± SE BMI (in kg/m2): 21.8 ± 0.521] and 19 youth with obesity (BMI: 35.7 ± 1.66), ages 15-21 y, frequency-matched by age and sex, underwent a fasting 10-h sodium [d3]-acetate intravenous infusion to determine the rate of appearance of acetate (Raacet) into the peripheral circulation before and after an oral dose of 20 g of lactulose. Pre- and post-lactulose Raacet values were determined at a quasi-steady state and changes between groups were compared using a quantile regression model. Acetate-derived hepatic DNL was measured in 11 subjects (6 youth with obesity) and its association with Raacet was assessed using Spearman correlation.Results: Mean ± SE Raacet was not different before lactulose ingestion between the 2 groups (7.69 ± 1.02 μmol · kg-1 · min-1 in lean youth and 7.40 ± 1.73 μmol · kg-1 · min-1 in youth with obesity, P = 0.343). The increase in mean ± SE Raacet after lactulose ingestion was greater in lean youth than in youth with obesity (14.7 ± 2.33 μmol · kg-1 · min-1 and 9.29 ± 1.44 μmol · kg-1 · min-1, respectively, P = 0.001). DNL correlated with Raacet, calculated as changes from the pre- to the post-lactulose steady state (ρ = 0.621; P = 0.046).Conclusions: These data suggest that youth with obesity ferment lactulose to a lesser degree than youth without obesity and that colonic acetate serves as a substrate for hepatic DNL.This trial was registered at clinicaltrials.gov as NCT03454828.

Parents of children with autism spectrum disorder (ASD) show increased levels of parenting stress, but only one study has examined this association before a diagnostic evaluation. We conducted a cross-sectional study of parenting stress in 317 low SES parents with children at-risk for ASD before a diagnostic evaluation. Multiple regression modeling evaluated the associations between parenting stress and parent and child factors. Parenting stress was negatively associated with social support and positively associated with active avoidance coping and parental worry. However, parenting stress was not associated with the child's ASD symptom severity or adaptive functioning, except for self-direction. Findings suggest parenting stress among parents of children at risk of ASD should be assessed prior to diagnosis. [ABSTRACT FROM AUTHOR]

Rationale: Epidemiologic studies demonstrate worse outcomes in women with cystic fibrosis (CF) than men. Women are colonized earlier with respiratory pathogens and have increased rates of pulmonary exacerbations after puberty and near ovulation. The etiology of this disparity is unclear, but sex hormones may contribute to these differences.Objectives: We sought to explore whether natural hormonal fluctuations and hormonal contraception associate with changes in lung function, respiratory symptoms, or inflammatory markers.Methods: We prospectively followed women with CF who were not on hormonal contraceptives and reported regular menstrual cycles. We captured study visits at points that corresponded with menses, ovulation, and the luteal phase. A subset of subjects were subsequently placed on a standard oral estrogen/progesterone combination contraceptive pill, ethinyl estradiol/norethindrone (loestrin), and reevaluated. Measurements included lung function, symptom questionnaires, sweat tests, blood for hormone concentrations, and sputum for inflammatory markers, bacterial density, and cytology.Results: Twenty-three women participated in this study. Hormone concentrations were as expected on and off hormonal contraception. At times of peak estrogen (ovulation), there was a significant increase in sputum proinflammatory cytokines (neutrophil-free elastase) and a corresponding pattern of decrease in lung function. Proinflammatory cytokines (IL-8, TNF-α, and neutrophil-free elastase) improved when placed on hormone contraception.Conclusions: Our results show that there are potentially important fluctuations in inflammatory biomarkers in the lungs that correlate with changes in lung function in women with CF. Larger studies evaluating the impact of sex hormones on airway inflammation and immune response are necessary to better understand the clinical impact of these responses. [ABSTRACT FROM AUTHOR]

Objective: The risk genotype for the common variant rs7903146 of the transcription factor 7-like-2 (TCF7L2) gene has been found to affect the incretin response in healthy and obese adults; however, whether a similar functional defect is also present in obese adolescents remains unexplored. Herein, we examined the functional effect of the rs7903146 variant in the TCF7L2 gene on the incretin effect and determined its translational metabolic manifestation by performing deep phenotyping of the incretin system, β-cell function relative to insulin sensitivity, the gastrointestinal-induced glucose disposal (GIGD) in obese youth with normal and impaired glucose tolerance.Research Design and Methods: Thirty-nine obese adolescents without diabetes (median age 15 [25th, 75th percentile 14, 18] years; BMI 37 [33, 43] kg/m2) were genotyped for the rs7903146 variant of TCF7L2 and underwent a 3-h oral glucose tolerance test (OGTT) followed by an isoglycemic intravenous glucose infusion (iso-intravenous glucose tolerance test [IVGTT]) to match the plasma glucose concentrations during the OGTT and a hyperglycemic clamp with arginine stimulation. The incretin effect was measured as 100 * (AUC-SROGTT - AUC-SRiso-IVGTT) / AUC-SROGTT, where AUC-SR = area under the curve of C-peptide secretion rate. Participants were grouped into tertiles according to the percentage incretin effect (high, moderate, and low) to describe their metabolic phenotype.Results: The presence of T risk allele for TCF7L2 was associated with a markedly reduced incretin effect compared with the wild-type genotype (0.3% [-7.2, 14] vs. 37.8% [12.5, 52.4], P < 0.002). When the cohort was stratified by incretin effect, the high, moderate, and low incretin effect groups did not differ with respect to anthropometric features, while the low incretin effect group exhibited higher 1-h glucose (P = 0.015) and a reduced disposition index, insulin sensitivity, and insulin clearance compared with the high incretin effect group. GIGD was reduced in the low incretin effect group (P = 0.001). The three groups did not differ with respect to intravenous glucose-induced insulin secretion and arginine response during the hyperglycemic clamp.Conclusions: A reduced incretin effect and its association with the TCF7L2 variant rs7903146 identify an early metabolic phenotype in obese youth without diabetes, featuring a higher plasma glucose peak at 1 h; lower insulin secretion, sensitivity, and clearance; and GIGD.

Background: Recent literature suggests that the Western diet's imbalance between high ω-6 (n-6) and low ω-3 (n-3) PUFA intake contributes to fatty liver disease in obese youth.Objectives: We tested whether 12 wk of a low n-6:n-3 PUFA ratio (4:1) normocaloric diet mitigates fatty liver and whether the patatin-like containing domain phospholipase 3 (PNPLA3) rs738409 variant affects the response.Methods: In a single-arm unblinded study, obese youth 9-19 y of age with nonalcoholic fatty liver disease were treated with a normocaloric low n-6:n-3 PUFA ratio diet for 12 wk. The primary outcome was change in hepatic fat fraction (HFF%), measured by abdominal MRI. Metabolic parameters included alanine aminotransferase (ALT), lipids, measures of insulin sensitivity, and plasma oxidized linoleic acid metabolites (OXLAMs). Outcomes were also analyzed by PNPLA3 rs738409 genotype. Wilcoxon's signed rank test, the Mann-Whitney U test, and covariance pattern modeling were used.Results: Twenty obese adolescents (median age: 13.3 y; IQR: 10.5-16.4 y) were enrolled and 17 completed the study. After 12 wk of dietary intervention, HFF% decreased by 25.8% (P = 0.009) despite stable weight. We observed a 34.4% reduction in ALT (P = 0.001), 21.9% reduction in triglycerides (P = 0.046), 3.28% reduction in LDL cholesterol (P = 0.071), and a 26.3% improvement in whole body insulin sensitivity (P = 0.032). The OXLAMs 9-hydroxy-octadecandienoic acid (9-HODE) (P = 0.011), 13-HODE (P = 0.007), and 9-oxo-octadecadienoic acid (9-oxoODE) (P = 0.024) decreased after 12 wk. HFF% declined in both the not-at-risk (CC/CG) and at-risk (GG) PNPLA3 rs738409 genotype groups, with significant (P = 0.016) HFF% reduction in the GG group. Changes in 9-HODE (P = 0.023), 9-oxoODE (P = 0.009), and 13-oxoODE (P = 0.003) differed between the 2 genotype groups over time.Conclusions: These data suggest that, independently of weight loss, a low n-6:n-3 PUFA diet ameliorates the metabolic phenotype of adolescents with fatty liver disease and that response to this diet is modulated by the PNPLA3 rs738409 genotype.This trial was registered at clinicaltrials.gov as NCT01556113.

Aim: To evaluate the impact of a dedicated nursing team on central line insertion success and catheter-related complications.Methods: Five nurses were trained in central line insertion and maintenance practices and replaced a team primarily comprised of neonatal-perinatal medicine fellows. A prospective observational cohort study with pre/post-intervention analysis was designed to compare certain aspects of central line insertion and related complications between the two models.Results: Six hundred and twenty peripherally inserted central catheters were attempted preintervention (period 1) in 325 infants, and 630 were attempted in 406 infants postintervention (period 2). Successful central line placement on the first attempt increased significantly from 56.6% in period 1-71.4% in period 2 (p < .001), and needle sticks per attempt decreased (3.5 versus 3; p = .03). All central line-related complications decreased from 12.8 per 1000 line days in period 1 to 5.5 in period 2 (rate ratio = 0.40; 95% confidence interval: 0.29, 0.65). The most significant reduction was noted in phlebitis (4.9-0.5 per 1000 line days; rate ratio = 0.10; 95% confidence interval: 0.03, 0.30)Conclusion: Implementation of a dedicated nursing-based central line team, skilled in insertion and certain aspects of catheter maintenance, significantly improved insertion rates and reduced line-related complications.

In 2018, the American Academy of Pediatrics warned consumers over the increasing use of imported infant formulas. The purpose of this study was to assess the usage of imported European infant formula among parents in a large urban private practice. An anonymous survey was distributed at well-child appointments to a convenience sample of parents at an urban private pediatric practice from November 2017 to March 2018. Of the 750 eligible respondents, 552 (74%) completed the survey. Of the parents using formula, 20% were using imported European infant formulas. The most commonly used formula was Holle (33%), and 72% were acquired from web-based third-party vendors. Parents chose to use these formulas because they believed that European formulas contained better ingredients. Only 8% of parents received information about European infant formula from their pediatricians. Pediatricians need to be aware of these formulas and their risks to educate families on the use and safety of these formulas. [ABSTRACT FROM AUTHOR]

Background: A significant number of newborns are affected by life-limiting or life-threatening conditions. Despite this prevalence, there are inconsistencies in attitudes toward, and delivery of, neonatal palliative care. Implementing neonatal palliative care practice requires a multidisciplinary, collaborative effort. Objective: To examine institutional and individual barriers to and facilitators of neonatal palliative care from both medical and nursing perspectives. Design/Setting/Subjects: A prospective cross-sectional study design was used to collect data using the Neonatal Palliative Care Attitude Scale (NiPCAS) survey from medical providers and nurses in a 64-bed level IV neonatal intensive care unit in the United States. The response rate was 67%. Measurements: The NiPCAS survey included 26 attitudinal questions on a Likert scale. The instrument included three subscales: organization, resources, and clinician, in addition to other questions. Results: Six facilitators to neonatal palliative care were identified: (1) support of palliative care by the health care team, (2) support of palliative care by medical and nursing practice, (3) agreement that palliative care is as important as curative care, (4) parental involvement in decision making, (5) recognition of the importance of palliative care education, and (6) prioritizing pain relief. Three barriers to neonatal palliative care were highlighted: (1) a physical environment that is not conducive to providing palliative care, (2) technological obligations and parental demands, and (3) the societal belief that babies should not die. In addition, there were differences between medical and nursing staffs' attitudes on several topics. Conclusions: Several facilitators and barriers of neonatal palliative care were identified. There were similarities and differences in perceptions of neonatal palliative care between medical and nursing staff. Future work should be done to strengthen facilitators and to mitigate barriers.

Congenital heart disease (CHD) survivors are at risk for neurodevelopmental disability (NDD), and recent studies identify genes associated with both disorders, suggesting that NDD in CHD survivors may be of genetic origin. Genes contributing to neurogenesis, dendritic development and synaptogenesis organize neural elements into networks known as the connectome. We hypothesized that NDD in CHD may be attributable to genes altering both neural connectivity and cardiac patterning. To assess the contribution of de novo variants (DNVs) in connectome genes, we annotated 229 published NDD genes for connectome status and analyzed data from 3,684 CHD subjects and 1,789 controls for connectome gene mutations. CHD cases had more protein truncating and deleterious missense DNVs among connectome genes compared to controls (OR = 5.08, 95%CI:2.81–9.20, Fisher's exact test P = 6.30E-11). When removing three known syndromic CHD genes, the findings remained significant (OR = 3.69, 95%CI:2.02–6.73, Fisher's exact test P = 1.06E-06). In CHD subjects, the top 12 NDD genes with damaging DNVs that met statistical significance after Bonferroni correction (PTPN11, CHD7, CHD4, KMT2A, NOTCH1, ADNP, SMAD2, KDM5B, NSD2, FOXP1, MED13L, DYRK1A; one-tailed binomial test P ≤ 4.08E-05) contributed to the connectome. These data suggest that NDD in CHD patients may be attributable to genes that alter both cardiac patterning and the connectome. [ABSTRACT FROM AUTHOR]
