儿童无创通气的局限性及气管插管介入时机选择

近年来,无创通气在儿童呼吸支持领域有了较快发展。无创通气无需气管插管,操作简便,对部分呼吸道疾病有较为满意的疗效。但是,无创通气不能完全替代有创机械通气。在有些疾病无创通气不仅有着较高的失败率,而且会因气管插管的延误导致病情恶化,增加患儿的病死率。在行无创通气之前需评估患儿是否适宜进行无创通气治疗。对于进行无创通气治疗的患儿需严密监护,动态观察生理指标和监测数据的变化,掌握好气管插管的时机,以免造成有创机械通气治疗的延误。     

Mental health, demographic, and risk behavior profiles of pregnant survivors of childhood and adult abuse

Our objective was to address the gap in knowledge about the extent to which perinatal mental health and risk behaviors are associated with childhood and adult experiences of abuse that arises because of barriers to screening and disclosure about past and current abuse. Survey data from an ongoing study of the effects of posttraumatic stress on childbearing were used to describe four groups of nulliparous women: those with no abuse history, adult abuse only, childhood abuse only, and abuse that occurred during both periods. The rates of abuse history disclosure were higher in the research context than in the clinical settings. Mental health morbidity and risk behaviors occurred in a dose-response pattern with cumulative abuse exposure. Rates of current posttraumatic stress disorder ranged from 4.1% among those never abused to 11.4% (adult only), 16.0% (childhood only), and 39.2% (both periods). Women abused during both periods also were more likely to be using tobacco (21.5%) and drugs (16.5%) during pregnancy. We conclude that mental health and behavioral risk sequelae affect a significant portion of both childhood and adult abuse survivors in prenatal care. The integration into the maternity setting of existing evidence-based interventions for the mental health and behavioral sequelae of abuse is needed.

Avoidant/restrictive food intake disorder symptoms in children: Associations with child and family variables

This study sought to determine the frequency of possible cases of avoidant/restrictive food intake disorder (ARFID) in a Portuguese sample of school-aged children and to assess the associations with child’s internalizing problems, BMI z-score and body dissatisfaction, and parents’ eating habits, attitudes and practices. We assessed 330 children through child’s and parents’measures. Fifty-one (15.5%) children were possible cases of ARFID based on their symptom’s presentation. There were no association between sex and possible cases of ARFID, and no significant differences between possible cases of ARFID and nonpossible cases of ARFID regarding age. Lower BMI z-score and anxiety/depression were associated with possible cases of ARFID.     

Initial Abdominal CT and Laboratory Findings Prior to Diagnosis of Crohn’s Disease in Children

PurposeTo identify initial abdominal computed tomography (CT) and laboratory findings prior to a diagnosis of Crohn’s disease (CD) in children.Materials and MethodsIn this retrospective study, patients (≤18 year-old) who were diagnosed with CD from 2004 to 2019 and had abdominal CT just prior to being diagnosed with CD were included in the CD group. Patients (≤18 years old) who were diagnosed with infectious enterocolitis from 2018 to 2019 and had undergone CT prior to being diagnosed with enterocolitis were included as a control group. We assessed the diagnostic performances of initial CT and laboratory findings for the diagnosis of CD using logistic regression and the area under the curve (AUC).ResultsIn total, 107 patients (50 CD patients, 57 control patients) were included, without an age difference between groups (median 13 years old vs. 11 years old, p=0.119). On univariate logistic regression analysis, multisegmental bowel involvement, mesenteric vessel engorgement, higher portal vein/aorta diameter ratio, longer liver longitudinal diameter, lower hemoglobin (≤12.5 g/dL), lower albumin (≤4 g/dL), and higher platelet (>320×10³/µL) levels were significant factors for CD. On multivariate analysis, multisegmental bowel involvement [odds ratio (OR) 111.6, 95% confidence interval (CI) 4.778–2605.925] and lower albumin levels (OR 0.9, 95% CI 0.891–0.993) were significant factors. When these two features were combined, the AUC value was 0.985 with a sensitivity of 96% and specificity of 100% for differentiating CD.ConclusionMultisegmental bowel involvement on CT and decreased albumin levels can help differentiate CD from infectious enterocolitis in children prior to a definite diagnosis of CD.     

The Influence of Intensive Nutritional Education on the Iron Status in Infants

Iron is an essential nutrient for a child’s proper development at every growth stage. It is crucial for the production of red blood and muscle cells, DNA replication, and the development of the brain, nervous and immune systems. Iron deficiency is the most common micronutrient deficiency in children worldwide. Despite widespread access to nutritional information for children, parents continue to make many feeding mistakes. This study aimed to assess whether any nutritional intervention would affect the iron status in children. The parents of 203 children were randomly assigned to one of two groups: the study group received intensive mobile nutritional education for a year, while the control group received no intervention. Blood tests were performed on both groups at the beginning of the study and one year later. The educational intervention resulted in statistically significantly higher levels of RBC (red blood cells; p = 0.020), HGB (haemoglobin; p = 0.039), HCT (haematocrit; p = 0.036), MCV (mean cell volume; p = 0.018) parameters and iron dietary intake (p ≤ 0.001). Even a non-targeted dietary intervention improves the iron status in children. As iron management is insufficient in most children, an iron-targeted nutritional intervention appears necessary.     

Family mealtime emotions and food parenting practices among mothers of young children: Development of the Mealtime Emotions Measure for Parents (MEM‐P)

Family mealtimes can be important for supporting children''s healthy development, yet the emotional context of mealtimes can vary considerably, likely impacting their overall success and enjoyment. Yet, despite having an important role, little is known about how parents emotionally experience mealtimes with their family. The first aim of the current study was to assess the factor structure of a novel self‐report measure to assess parents’ emotional responses experienced during family mealtimes (Mealtime Emotions Measure for Parents; MEM‐P). The second aim was to examine relationships between maternal mealtime emotions and their food parenting practices. Mothers of children aged between 1.5 and 6 years participated in this study. Mothers were invited to complete an online questionnaire measuring family mealtime emotions, anxiety, depression and food parenting practices. Exploratory factor analysis produced a three‐factor solution comprising both positive and negative emotion subscales: MEM‐P Efficacy; MEM‐P Anxiety; MEM‐P Stress and Anger. Mothers'' positive mealtime emotions (mealtime efficacy) were related to greater use of practices promoting autonomy, providing a healthy home food environment, and modelling healthy eating. Higher anxiety about mealtimes was related to greater reports of child control over eating, and mealtime stress and anger was associated with greater use of food to regulate emotions. These findings highlight novel relationships between how mothers emotionally experience family mealtimes and the food parenting practices they use with their children. It is important to develop resources to help promote positive maternal experiences of family mealtimes and food‐based interactions.     

The seasonal relationships between household dietary diversity and child growth in a rural Timor‐Leste community

Both child growth and dietary diversity are poor in rural Timor‐Leste. The rainy season is associated with food scarcity, yet the association between seasonal scarcity, food diversity, and child growth is underdocumented. This study assesses the relationship between household dietary diversity and children''s standardized growth across the 2018 food‐scarce (April–May; post‐rainy period) and post‐harvest (October) seasons in the agricultural community of Natarbora, on the south‐coastal plains of Timor‐Leste. We conducted household interviews and collected anthropometric data across 98 and 93 households in the post‐rainy and post‐harvest periods, respectively. Consumed household foods were obtained via 24‐h diet recalls and were subsequently categorized into a nine‐food‐group dietary diversity score (DDS; number of different food groups consumed). The DDS was related to children''s standardized short‐term growth (z‐weight, z‐body mass index [BMI] and percent change in weight over the harvest season) via linear mixed models. Across seasons, DDS increased from 3.9 (standard deviation [SD] = 1.0) to 4.3 (SD = 1.4; p < 0.05). In the post‐rainy season, children in high DDS households had higher z‐weight than those in low DDS households and higher z‐BMI than children in medium and low DDS households. In the post‐harvest period, household DDS did not predict children''s z‐weight but predicted z‐BMI. Consumption of protein‐rich foods, particularly animal‐source foods and legumes, in low‐ and medium‐DDS households may be associated with improved child growth. While consuming more animal‐source foods in the post‐rainy season would be ideal, promoting the consumption of locally grown legumes, such as beans and pulses, may facilitate better nutritional outcomes for more children in rural Timor‐Leste.
