Intraoperative ultrasound for surgical resection of high-grade glioma and glioblastoma: a meta-analysis of 732 patients.

PURPOSE: Here, we conducted a meta-analysis to explore the use of intraoperative ultrasound (iUS)-guided resection in patients diagnosed with high-grade glioma (HGG) or glioblastoma (GBM). Our aim was to determine whether iUS improves clinical outcomes compared to conventional neuronavigation (CNN). METHODS: Databases were searched until April 21, 2023 for randomized controlled trials (RCTs) and observational cohort studies that compared surgical outcomes for patients with HGG or GBM with the use of either iUS in addition to standard approach or CNN. The primary outcome was overall survival (OS). Secondary outcomes include volumetric extent of resection (EOR), gross total resection (GTR), and progression-free survival (PFS). Outcomes were analyzed by determining pooled relative risk ratios (RR), mean difference (MD), and standardized mean difference (SMD) using random-effects model. RESULTS: Of the initial 867 articles, only 7 articles specifically met the inclusion criteria (1 RCT and 6 retrospective cohorts). The analysis included 732 patients. Compared to CNN, the use of iUS was associated with higher OS (SMD = 0.26,95%CI=[0.12,0.39]) and GTR (RR = 2.02; 95% CI=[1.31,3.1]) for both HGG and GBM. There was no significant difference in PFS or EOR. CONCLUSION: The use of iUS in surgical resections for HGG and GBM can improve OS and GTR compared to CNN, but it did not affect PFS. These results suggest that iUS reduces mortality associated with HGG and GBM but not the risk of recurrence. These results can provide valuable cost-effective interventions for neurosurgeons in HGG and GBM surgery.

A Randomized Controlled Cluster Trial of an Obesity Prevention Program for Children with Special Health Care Needs: Methods and Implications.

Children with disabilities have higher prevalence estimates of obesity than typically developing children. The Healthy Caregivers-Healthy Children Phase 3 (HC3) project implemented an obesity prevention program adapted for children with special health care needs (CSHCN) that includes dietary intake and physical activity (PA) components. The primary outcome was a change in dietary intake, PA, and the body mass index (BMI) percentile. Ten childcare centers (CCCs) serving low-resource families with ≥30 2- to 5-year-olds attending were randomized to either the intervention (n = 5) or control (n = 5). The HC3 CCCs received (1) snack, beverage, PA, and screen time policies via weekly technical assistance; (2) adapted lesson plans for CSHCN; and (3) parent curricula. The control CCCs received a behavioral health attention curriculum. HC3 was delivered over three school years, with data collected at five different timepoints. It was delivered weekly for six months in year one. To ensure capacity building, the HC3 tasks were scaled back, with quarterly intervention delivery in year 2 and annually in year 3. Adaptations were made to the curriculum to ensure appropriate access for CSHCN. Given that the program was being delivered during the COVID-19 pandemic, special modifications were made to follow CDC safety standards. The primary outcome measures included the Environment and Policy Assessment and Observation (EPAO) tool, standardized dietary intake and PA assessments, and the child BMI percentile. CCCs are an ideal setting for targeting CSHCN for obesity prevention efforts as they provide an opportunity to address modifiable risk factors.

[Cow's milk allergy: diagnostic process. Expert consensus]. / Alergia a las proteínas de la leche de vaca: proceso diagnóstico. Consenso interdisciplinario de expertos.

Cow's milk protein can cause food allergy. The different mechanisms of action involved, the clinical variability depending on the stage of pediatric life in which it manifests, leads to difficulties in its approach, with the risk of under- or over-diagnosis. Professionals from various areas intervene in this process and their interaction is recommended. That is why the objective of this consensus has been to reflect the updated knowledge in an interdisciplinary mode, generating recommendations for its correct diagnosis. We have worked with the Delphi method to add to the scientific evidence, the experience from neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology. We think that this interdisciplinary approach will be of practical use and will promote more comprehensive care for these patients.

Las proteínas de la leche de vaca pueden causar alergia alimentaria. Los distintos mecanismos de acción involucrados y la variabilidad clínica según la etapa de la vida pediátrica en la que se manifieste ocasionan dificultades en su abordaje, con riesgo de sub- o sobrediagnóstico. En este proceso, intervienen profesionales de diversas áreas y es recomendable su interacción. Es por ello que el objetivo de este consenso ha sido reflejar el conocimiento actualizado desde la interdisciplina, generando recomendaciones para su correcto diagnóstico. Hemos trabajado con el método de Delphi para sumarle a la evidencia científica, la experiencia proveniente de neonatólogos, pediatras, especialistas en alergia, nutrición y gastroenterología. Pensamos que este enfoque interdisciplinario de trabajo va a resultar de utilidad práctica y promoverá una atención más integral de estos pacientes.

[Cow's milk allergy treatment. An expert consensus]. / Tratamiento de la alergia a la proteína de la leche de vaca. Consenso interdisciplinario de expertos.

The treatment of cow's milk protein allergy is based on the complete elimination of cow's milk protein from the diet. To achieve remission of symptoms and future tolerance, exclusion must be total. In formula fed infants the extensively hydrolysed formula is the most appropriate option in mild or moderate forms, while those based on amino acids are reserved for the most severe cases. The treatment time, the acquisition of tolerance and the moment for the oral provocation test will vary according to the clinical picture, the immunological mechanism involved and the age of the patient. The aim of this consensus has been to reflect the updated knowledge together with the experience of neonatologists, pediatricians, experts in allergy, nutrition and gastroenterology.

El tratamiento de la alergia a las proteínas de la leche de vaca se basa en la eliminación completa de las proteínas de leche de vaca de la dieta del niño y de la madre en los que reciben leche materna. Para lograr la remisión de los síntomas y la tolerancia futura, la exclusión debe ser total. En los niños que reciben fórmula, esta deberá tener hidrolizado extenso de proteínas en las formas leves o moderadas, mientras que aquellas a base de aminoácidos se reservan para los casos más graves. El tiempo de tratamiento, la adquisición de tolerancia y el momento para la prueba de provocación oral van a variar según el cuadro clínico, el mecanismo inmunológico implicado y la edad del paciente. El objetivo de este consenso ha sido reflejar el conocimiento actualizado junto con la experiencia de neonatólogos, pediatras, especialistas en alergia, nutrición y gastroenterología.

Functional alterations of two novel MC4R mutations found in Argentinian pediatric patients with early onset obesity.

Loss-of-function mutations in melanocortin-4 receptor (MC4R) are the most common cause of monogenic obesity, a severe type of early-onset obesity. Our aim was to determine the prevalence of MC4R mutations in a cohort of 97 Argentinian children with early-onset obesity. We found two novel mutations (p.V52E and p.G233S) and estimated a prevalence of 2.1%. We investigated the pathogenicity of mutations in HEK293T cells expressing wild-type or mutant MC4R and found that both mutants exhibited reduced plasma membrane expression and altered agonist-induced cAMP responses, with no changes in basal activity. Besides, MC4R G233S mutant demonstrated an altered agonist-dependent inhibition of voltage-gated calcium channels type 2.2. Results using a Gαs protein inhibitor suggest that the G233S mutation could be recruiting a different G-protein signaling pathway. The identification of new mutations in MC4R and characterization of their functional impact provide tools for the diagnosis and treatment of monogenic obesity.

Social Challenges as a Consequence of the COVID-19 Pandemic among South Florida Preschool Children with Disability and Obesity.

The COVID-19 pandemic has negatively impacted the childcare industry over the past two years. This study examined how pandemic-related challenges impacted preschool-aged children by disability and obesity status. Participants were 216 children (80% Hispanic, 14% non-Hispanic Black) aged 2 to 5 years in 10 South Florida childcare centers. In November/December 2021, parents completed a COVID-19 Risk and Resiliency Questionnaire, and body mass index percentile (BMI) was collected. Multivariable logistic regression models examined the association of COVID-19 pandemic-related social challenges (transportation, employment) and child BMI and disability status. As compared to normal-weight children, those families with a child who was obese were more likely to report pandemic-related transportation (OR: 2.51, 95% CI: 1.03-6.28) challenges and food insecurity (OR: 2.56, 95% CI: 1.05-6.43). Parents of children with disabilities were less likely to report that food did not last (OR: 0.19, 95% CI: 0.07-0.48) and that they could not afford balanced meals (OR: 0.33, 95% CI: 0.13-0.85). Spanish-speaking caregivers were more likely to have a child who was obese (OR: 3.04, 95% CI: 1.19-8.52). The results suggest that COVID-19 impacts obese preschool children from Hispanic backgrounds, while disability was a protective factor.

Risk and resilience of well-being in caregivers of young children in response to the COVID-19 pandemic.

The COVID-19 pandemic is impacting communities worldwide, with direct effects of illness and mortality, and indirect effects on economies, workplaces, schools/daycares, and social life. However, we understand very little about the effects of this pandemic on families of young children. We used a risk and resilience model to evaluate the effects of the pandemic on mental health in diverse caregivers (N = 286) with children ages birth to 5. We evaluated the hypotheses that (a) pandemic stress and caregiver-reported child psychosocial concerns correlate with caregivers' mental health symptoms and (b) caregivers' pandemic-related self-efficacy and coping mediate these relationships. Caregivers completed surveys in April-May 2020 assessing pandemic stress (e.g., health, finances, and housing), child psychosocial problems, coping strategies, and self-efficacy to manage family needs. Our primary outcome was caregivers' self-reported changes in mental health symptoms since the outbreak. Path analysis revealed that higher pandemic stress was associated with caregivers' reduced confidence in meeting their family's needs related to COVID-19, which correlated with worse caregiver mental health symptoms. Greater child psychosocial problems also predicted worse caregiver mental health symptoms. Findings suggest that pandemic stress, child psychosocial problems, and caregiver self-efficacy are interrelated in their influence on caregivers' mental health. While further research is needed to examine strategies to foster resilience and buffer the pandemic's effects on caregiver mental health, this is a first step in evaluating the psychosocial effects of this pandemic in families of young children. Clinical implications are discussed for a tiered response to mitigate the pandemic's impacts on family functioning.

Plasma levels of ghrelin, des-acyl ghrelin and LEAP2 in children with obesity: correlation with age and insulin resistance.

OBJECTIVE: The octanoylated peptide hormone ghrelin regulates appetite and glycaemic control. Des-acyl ghrelin abolishes some effects of ghrelin, but does not bind to ghrelin receptor. LEAP2 is a novel ligand for ghrelin receptor that blocks the effects of ghrelin. Some evidences show that plasma levels of these peptides are altered in adults with obesity, but their levels in childhood obesity remain poorly studied. Therefore, the objective of this study was to assess fasting plasma levels of ghrelin, des-acyl ghrelin and LEAP2 in children with normoweight, overweight/obesity and their association with different anthropometric and metabolic variables. DESIGN: A total of 42 females and 40 males, ages 3-12 years old were enrolled as a cross-sectional cohort. RESULTS: Plasma levels of des-acyl ghrelin and LEAP2 (but not ghrelin) were lower and ghrelin/des-acyl ghrelin ratio was higher in children with overweight/obesity. Des-acyl ghrelin negatively correlated with age, BMI z-score, insulin and HOMA index, and the correlations were stronger in children with overweight/obesity. LEAP2 levels negatively correlated with BMI z-score. No gender differences were found. CONCLUSIONS: Our findings suggest that ghrelin tone is increased in childhood obesity, due to a decrease on plasma levels of des-acyl ghrelin and LEAP2, and that des-acyl ghrelin is associated to insulin resistance, particularly in children with overweight/obesity.

Introducción: La malnutrición y la deficiencia de micronutrientes son complicaciones frecuentes en los pacientes con parálisis cerebral (PC). Objetivo: Analizar los niveles de vitamina D (VitD) en pacientes PC en Nutrición Enteral Domiciliaria (NED). Material y Métodos: Estudio retrospectivo analítico de corte transversal. Se incluyeron pacientes PC, e/ 2-18 años, con dosaje de VitD al final del invierno 2021. Se analizó: sexo, edad, discapacidad por Gross Motor Scale (GMS), estado nutricional, drogas antiepilépticas, fórmula, aporte de VitD, volumen, vía de acceso, gasto energético basal (GEB). Se agruparon: Grupo I (GI VitD ≥ 30 ng/ml) GII (VitD ≤ 29 ng/ml). Resultados: se incluyeron 34 pacientes PC, 15 femeninos (44,11 %), edad media 10,87 años (DS 4,78), todos fueron grado V (GMS). La media de Z score de IMC (OMS) fue -1,33 (DS 3,14). Todos recibieron NE diaria. El aporte medio fue de 1270 Kcal (DE:243), 1,16 (Kcal sobre lo estimado según Schofield). Las fórmulas aportaron el 80% del requerimiento de VitD. Los niveles sanguíneos de VitD mostraron: 16 pacientes ≥ de 30 ng/ml y 18 ≤ 29 ng/ml. 14 fueron deficientes y 4 insuficientes. El 59% (20) de los pacientes recibían medicación anticonvulsivante. No se encontraron diferencias significativas entre G1 y G2 para sexo, edad, Z score de IMC, aporte de VitD, calorías recibidas/ GMB y medicación anticonvulsivante. Conclusión: El alto porcentaje de pacientes PC pediátricos con niveles subóptimos de VitD muestra que se trata de una población de riesgo y sugiere la necesidad del chequeo sistemático para una adecuada prevención y tratamiento

Introduction: Malnutrition and micronutrient deficiencies are frequent complications in patients with cerebral palsy (CP). Objective: to analyze the levels of vitamin D (VitD) in CP patients receiving Home Enteral Nutrition (HEN). Material and Methods: Retrospective analytical cross-sectional study. CP patients, from 2 to 18 years old, with measured VitD at the end of winter 2021, were included. The following study variables were analyzed: sex, age, disability by Gross Motor Scale (GMS), nutritional status, antiepileptic drugs, formula, VitD intake, volume, access route, basal energy expenditure (BEE), according to Schofield P/T. They were grouped: Group I (GI VitD ≥ 30 ng/ml) GII (VitD ≤ 29 ng/ml). Results: 34 CP patients were included, 15 female (44.11 %), mean age 10.87 years (SD 4.78), all grade V (GMS). The mean BMI Z score (WHO) was -1.33 (SD 3.14). EN was daily in all, 33 due to gastrostomy and 1 due to SNG. The average contribution 1270 Kcal (DS243), 1.16 (Kcal received according to Schofield). The formulas provided 80 % of the VitD requirement. VitD blood levels showed: 16 patients (47 %) ≥ 30 ng/ml and 18 (52 %) ≤ 29 ng/ml. 14 (41.17 %) were deficient and 4 insufficient (11.76 %). 59 % (20) of the patients received anticonvulsant medication. No significant differences were found between G1 and G2 for sex, age, BMI Z score, VitD intake, calories received/GMB and anticonvulsant medication. Conclusion: The high percentage of pediatric CP patients with suboptimal levels of Vit D shows that it is a population at risk and suggests the need for systematic check-up for adequate prevention and treatment

No severe complications were recorded (hospitalizations, bronchial aspiration, death). Conclusions: an improvement in nutritional status and no severe complications were observed in the period studied

Ryan White CARE Act Part D: matches and gaps in political commitment and local implementation.

This article demonstrates the opportunities for and challenges of the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act Part D to implementing its mandate for comprehensive family-centered systems of care for women, infants, children, and youth with HIV/AIDS. Part D legislation should promote practices addressing families with models for basic security, judiciously embrace those universal public health policies aiming to improve children's overall welfare, and consistently repudiate those policies infringing on human rights of women infected with HIV, or ignoring their children's basic needs. The proposed revisions to Part D implementation may renew its political commitment to serving the needs of families who are HIV affected.
