CROSS-CULTURAL ADAPTATION AND VALIDATION OF THE MONTREAL CHILDREN'S HOSPITAL FEEDING SCALE INTO BRAZILIAN PORTUGUESE.

OBJECTIVE: To cross-culturally adapt and validate the Montreal Children's Hospital Feeding Scale (MCH-FS) into Brazilian Portuguese. METHODS: The MCH-FS, originally validated in Canada, was validated in Brazil as Escala Brasileira de Alimentação Infantil (EBAI) and developed according to the following steps: translation, production of the Brazilian Portuguese version, testing of the original and the Brazilian Portuguese versions, back-translation, analysis by experts and by the developer of the original questionnaire, and application of the final version. The EBAI was applied to 242 parents/caregivers responsible for feeding children from 6 months to 6 years and 11 months of age between February and May 2018, with 174 subjects in the control group and 68 ones in the case group. The psychometric properties evaluated were validity and reliability. RESULTS: In the case group, 79% of children were reported to have feeding difficulties, against 13% in the control group. The EBAI had good internal consistency (Cronbach's alpha=0.79). Using the suggested cutoff point of 45, the raw score discriminated between cases and controls with a sensitivity of 79.4% and specificity of 86.8% (area under the ROC curve=0.87). CONCLUSIONS: The results obtained in the validation process of the EBAI demonstrate that the questionnaire has adequate psychometric properties and, thus, can be used to identify feeding difficulties in Brazilian children from 6 months to 6 years and 11 months of age.

Assessment of clinical practice procedures among Registered Dietitian Nutritionists for identifying feeding dysfunction in the pediatric population.

BACKGROUND & AIMS: Feeding dysfunction is common in children. Efficient processes to identify and treat feeding dysfunction are not commonly known or used among healthcare practitioners. The aim of this study was to develop and validate a survey tool to assess current practice procedures used by Registered Dietitian Nutritionists (RDN) in identifying, diagnosing, and treating feeding dysfunction in children 0-18 years of age. METHODS: A survey was developed and distributed to gather information on RDN practice procedures, prevalence of pediatric feeding dysfunction, identification of pediatric feeding dysfunction, and method of treatment used to address pediatric feeding dysfunction. Emails were sent to 4449 RDNs in United States. All participants were classified by the Commission on Dietetic Registration (CDR) as clinical dietitians. Distribution and frequency of survey responses were assessed, and in the case of qualitative questions, were categorized according to themes identified. RESULTS: Responses of RDNs from 41 states completed 341 total surveys, 179 surveys were included in data analysis. Eighty percent of participants do not use a specific screening tool to identify feeding dysfunction. Results concerning feeding therapy strategies and terms used by RDNs to describe feeding dysfunction were highly varied or lacking. Increased inclusion of RDNs on interdisciplinary teams was indicated by 80% of participants. The majority of participants indicated they refer patients with feeding dysfunction to other practitioners instead of providing feeding therapy themselves. CONCLUSIONS: Standardized screening, diagnostic, and treatment protocols regarding feeding dysfunction are needed to provide consistent and comprehensive care for the pediatric population. Use of these protocols among RDNs would enable them to improve feeding abilities in more patients earlier in individual child development.

RESUMO Objetivo: Realizar a adaptação transcultural e a validação da escala Montreal Children's Hospital Feeding Scale (MCH-FS) para a língua portuguesa falada no Brasil. Métodos: A MCH-FS, originalmente validada no Canadá, foi validada no Brasil como Escala Brasileira de Alimentação Infantil (EBAI) e desenvolvida a partir das seguintes etapas: tradução, montagem da versão em português brasileiro, teste da versão em inglês e da versão em português brasileiro, retrotradução, análise por experts e autora do questionário original e aplicação da versão final em estudo. A EBAI foi aplicada em 242 pais/cuidadores responsáveis pela alimentação de crianças de seis meses a seis anos e 11 meses de idade no período de fevereiro a maio de 2018, sendo 174 no grupo controle e 68 no grupo dos casos. As propriedades psicométricas avaliadas foram validade e confiabilidade. Resultados: No grupo dos casos, 79% dos pais/cuidadores relataram dificuldades alimentares, e no grupo controle, 13%. A EBAI apresentou boa consistência interna (alfa de Cronbach=0,79). Utilizando-se o ponto de corte sugerido de 45, o escore bruto (raw score) diferenciou casos de controles com sensibilidade de 79,4% e especificidade de 86,8% (área sob a curva ROC=0,87). Conclusões: Os resultados obtidos na validação da EBAI evidenciaram medidas psicométricas adequadas. Portanto, a escala pode ser utilizada na identificação de dificuldades alimentares em crianças brasileiras de seis meses a seis anos e 11 meses idade.

Instrument to Identify Food Neophobia in Brazilian Children by Their Caregivers.

This study aimed to develop a specific instrument to evaluate food neophobia focused on Brazilian children and to perform the content validation and internal semantic consistency and reproducibility evaluation of the instrument. Three steps were necessary to conduct the study: (i) development of the instrument, (ii) internal validation (content validation and semantic evaluation) of the food neophobia instrument using 22 experts in the first round and 20 of them in the second round, (iii) evaluation of the internal consistency and reproducibility of the instrument with the children's caregivers, using the test-retest (where the same caregiver-n = 22-answered twice, with 24 h interval) and comparing responses between two caregivers (n = 44) of the same children (n = 22). We developed an instrument in Brazilian-Portuguese to evaluate children's food neophobia based on the caregivers' perceptions with 25 items divided into three domains (neophobia in general, neophobia for fruits and neophobia for vegetables). Our results indicated that the instrument has excellent internal consistency (>0.9) and reproducibility (>0.9) when answered by the caregiver who knows the child's eating habits, indicating reliability to be applied in Brazil. In addition, when the two caregivers answered the instrument, we found a good reproducibility (>0.6), confirming the possibility to be answered by one of the caregivers. Further studies are necessary to complete external validation with a representative sample of the target group in Brazil, showing nationwide the profile of the population. The potential of a neophobia study would contribute to the implementation of effective strategies and guidelines to support parents and health professionals, especially those involved in health and nutrition, to identify traces of food neophobia or neophobic behavior. By accurately measuring food neophobia in children, families can prevent nutritional deficiencies throughout adolescence and adulthood, improving eating habits. Children usually have neophobias similar to the ones presented by their parents-and when early detected, these neophobias can be addressed.

Psychometric Properties of the Infant and Child Feeding Questionnaire.

OBJECTIVES: To report the updated psychometric properties of a child feeding questionnaire and to report the psychometric properties of a screening tool developed from this questionnaire. A secondary objective was to consider if items from a behavior checklist embedded within the Infant and Child Feeding Questionnaire may be useful in making referrals for feeding problems. STUDY DESIGN: Caregivers of children younger than the age of 4 years with pediatric feeding disorders (as defined by International Classification of Diseases, Ninth Revision, criteria) were recruited from 2 outpatient clinics. A comparison group with no feeding problems was recruited during well child checks from community clinics. Caregivers completed a demographic questionnaire and a child feeding questionnaire. Exploratory and confirmatory analyses identified questionnaire items that differentiated groups. Remaining items were summed and area under the curve, sensitivity, and specificity values were calculated to describe the resulting screening tool. ORs of behaviors from the embedded behavior checklist were calculated to determine whether specific behaviors could be useful for referrals. RESULTS: Responses of 989 caregivers (pediatric feeding disorders, n = 331; no feeding problems, n = 650) were obtained. Six questions of the child feeding questionnaire differentiated groups accounting for 60% of variance. Sensitivity (73%) and specificity (93%) were greater when any 2 or more of these 6 items was endorsed. Three items of the embedded feeding behaviors checklist show promise for referrals to specific provider disciplines. CONCLUSIONS: A pediatric feeding disorders screening tool consisting of 6 questions from a child feeding questionnaire is psychometrically sound. Use of this tool may expedite referrals for treatment. Further study of the embedded behavior checklist may be useful for clinical referrals.

Functional Improvements of Speech, Feeding, and Sleep After Lingual Frenectomy Tongue-Tie Release: A Prospective Cohort Study.

Recent studies suggest that speech, solid feeding, and sleep difficulties may be linked to restricted tongue function. Children with tongue restrictions and speech, feeding, and sleep issues underwent lingual frenectomies with a CO2 laser, paired with myofunctional exercises. Questionnaires were completed before, 1 week after, and 1 month following treatment. Thirty-seven patients participated in the study (mean age 4.2 years [range 13 months to 12 years]). Overall, speech improved in 89%, solid feeding improved in 83%, and sleep improved in 83% of patients as reported by parents. Fifty percent (8/16) of speech-delayed children said new words after the procedure (P = .008), 76% (16/21) of slow eaters ate more rapidly (P < .001), and 72% (23/32) of restless sleepers slept less restlessly (P < .001). After tongue-tie releases paired with exercises, most children experience functional improvements in speech, feeding, and sleep. Providers should screen for oral restrictions in children and refer for treatment when functions are impaired.

Problems of feeding, sleeping and excessive crying in infancy: a general population study.

OBJECTIVE: To study regulatory problems (RPs) of feeding, sleeping and excessive crying in infancy, and explore the influence of maternal mental health problems and parent-child relationship problems. DESIGN AND SETTING: Data were collected in the general child health surveillance delivered to infant families by community health nurses (CHNs). Information on CHNs' assessments and conclusions were obtained on 2598 infants and merged with data from national registers. Descriptive statistics and logistic regression models were used to study RPs in early and late infancy, and the influences due to child, family and parent-child relationship problems. RESULTS: Combined RPs (C-RPs), defined as two or more simultaneous problems of feeding, sleeping or excessive crying, was identified in 2.9% and 8.6% of the population between age 2-6 and 8-11 months, respectively. Low maternal schooling and immigrant parents were associated with an increased risk of late C-RPs, but RPs in early infancy stand out as the main predictor of late C-RPs OR 3.4 (95% CI 1.8 to 6.6), and the effect of early maternal mental health problems and parent-child relationship problems seem to be mediated by early C-RPs. CONCLUSIONS: Combined problems of feeding, sleeping or excessive crying may exist throughout infancy independently of exposures to maternal mental health problems and parent-child relationship problems. The results indicate that infants with RPs exceeding age 2 months need special attention, in clinical as well as community settings. Suggested intervention includes specific guidance to the parents to help them understand and regulate their infant's sensitivity and reactions.

Self-Focused Attention and Depressive Symptoms in Adults with Autistic Spectrum Disorder (ASD).

Adults with autistic spectrum disorder (ASD) are at high risk of developing comorbid depressive symptoms and in the general population self-focused attention has been associated with depression. Here, we aimed to examine the relationships between aspects of self-focused attention and symptoms of depression in individuals with a diagnosis of ASD. 113 adults with a diagnosis of ASD completed self-report questionnaires. Results found that higher levels of brooding, and to a lesser degree, reflection predicted increased depressive symptoms. However, higher levels of private self-consciousness actually predicted decreased depressive symptoms. Differential relationships were observed for males and females. The current study highlights the importance of using a multidimensional approach to examining self-focused attention in ASD, and its important relationship with depression.

Development of the Trying New Foods Scale: A preschooler self-assessment of willingness to try new foods.

Food neophobia, or reluctance to try new foods, emerges typically in early childhood and can impact child food acceptance and dietary quality. Measures of child neophobia have largely been developed from an adult point of view and the items focusing on fear and disgust were created from observations of children's behaviors or from adult assumptions regarding the source of children's reluctance to try new foods. Using group interviews with 3-5-y-old children (n = 229) we investigated what the experience of being asked trying new foods is like for preschoolers. From their answers, we crafted a new assessment, The Trying New Foods Scale, designed to ask children about their self-competence to try new foods. Next, we measured preschoolers' responses (n = 233; 3-5 years of age; 107 boys, 126 girls) to these items and observed their willingness to taste 7 novel foods and their affective ratings of the foods as measures of criterion validity. A principal components analysis (PCA) revealed a single 9-item component for the Trying New Foods Scale (mean ±â€¯s.d. = 3.08 ±â€¯0.70; α = 0.88). Children's Trying New Foods Scale score positively correlated with their willingness to try foods ratio (r = 0.21, p = .001). Initial findings indicate that the Trying New Foods Scale for preschoolers has good psychometric characteristics, including preliminary evidence of criterion validity. Children who perceived themselves as more willing to try foods actually performed the behavior of trying more foods and rated the foods more favorably than children who reported lower self-competence to try foods. Understanding neophobia from the perspective of the young child, and their perceptions of self-competence related to trying new foods, may facilitate our ability to evaluate young children's food acceptance patterns.

Postprandial High-Resolution Impedance Manometry Identifies Mechanisms of Nonresponse to Proton Pump Inhibitors.

BACKGROUND & AIMS: Recognition of rumination and supragastric belching is often delayed as symptoms may be mistakenly attributed to gastroesophageal reflux disease. However, distinct from gastroesophageal reflux disease, rumination and supragastric belching are more responsive to behavioral interventions than to acid-suppressive and antireflux therapies. Postprandial high-resolution impedance manometry (PP-HRIM) is an efficient method to identify rumination and belches. We investigated the distribution of postprandial profiles determined by PP-HRIM, and identified patient features associated with postprandial profiles among patients with nonresponse to proton pump inhibitors (PPIs). METHODS: We performed a retrospective analysis of PP-HRIM studies performed on 94 adults (mean age, 50.6 y; 62% female) evaluated for PPI nonresponsiveness at an esophageal referral center, from January 2010 through May 2016. Following a standard esophageal manometry protocol, patients ingested a solid refluxogenic test meal (identified by patients as one that induces symptoms) with postprandial monitoring up to 90 minutes (median, 50 min). Patients were assigned to 1 of 4 postprandial profiles: normal; reflux only (>6 transient lower esophageal sphincter relaxations (TLESRs)/h); supragastric belch (>2 supragastric belches/h), with or without TLESR; or rumination (≥1 rumination episode/h) with or without TLESR and supragastric belching. The primary outcome was postprandial profile. RESULTS: Of the study participants, 24% had a normal postprandial profile, 14% had a reflux-only profile, 42% had a supragastric belch profile, and 20% had a rumination profile. In multinomial regression analysis, the rumination group most frequently presented with regurgitation, the supragastric belch and rumination groups were younger in age, and the reflux-only group had a lower esophagogastric junction contractile integral. The number of weakly acidic reflux events measured by impedance-pH monitoring in patients receiving PPI therapy was significantly associated with frequency of rumination episodes and supragastric belches. CONCLUSIONS: In a retrospective analysis of 94 nonresponders to PPI therapy evaluated by PP-HRIM, we detected an abnormal postprandial pattern in 76% of cases: 42% of these were characterized as supragastric belching, 20% as rumination, and 14% as reflux only. Age, esophagogastric junction contractility, impedance-pH profiles, and symptom presentation differed significantly among groups. PP-HRIM can be used in the clinic to evaluate mechanisms of PPI nonresponse.

Feeding Problems in Infants and Children: Assessment and Etiology.

Feeding problems in infants and young children are common. In healthy children who are developing and growing normally, feeding problems are usually not serious and can be managed conservatively by reassuring the family and providing them with anticipatory guidance and follow-up. A majority of serious childhood feeding problems occur in children who have other medical, developmental, or behavioral problems. These are best evaluated and treated by an interprofessional team who can identify and address issues in the medical and/or developmental history, problems with oral motor control and function, problems with swallowing, and behavioral and/or sensory issues that may interfere with normal feeding.

Developmental Origins of Rumination in Middle Childhood: The Roles of Early Temperament and Positive Parenting.

Rumination, a thinking style characterized by a repetitive inward focus on negative cognitions, has been linked to internalizing disorders, particularly depression. Moreover, research suggests that rumination may be a cognitive vulnerability that predisposes individuals to psychopathology. Surprisingly little is known, however, about the etiology and development of rumination. The present study examined the role of specific components of child temperamental negative emotionality (sadness, fear, anger) and effortful control (inhibition), as well as parenting behaviors during early childhood on the development of rumination in middle childhood. Early childhood (age 3) temperament and parenting behaviors were assessed observationally and rumination was self-reported in middle childhood (age 9) in a large community sample (N = 425; 47.1% female). Two significant interactions emerged. First, temperamental anger interacted with inhibitory control (IC) such that high anger and low IC predicted higher levels of rumination, whereas low anger and low IC predicted lower levels of rumination. Second, IC interacted with parenting such that children with low IC and positive parenting had lower levels of rumination. In contrast, children with high IC reported similar levels of rumination regardless of parenting quality. Overall, these findings highlight the interplay of early IC with temperamental anger and positive parenting in the development of ruminative tendencies in middle childhood.

Long-term Follow-up of Adolescents Treated for Rumination Syndrome in an Inpatient Setting.

OBJECTIVES: Although several studies have demonstrated the short-term benefit of the behavioral treatment of rumination syndrome, few have investigated the long-term outcomes. Studies reporting long-term benefit have involved combined pediatric and adult samples or have examined outcomes of patients involved in various types of treatment. The purpose of the present study was to examine several aspects of long-term outcome in adolescent patients who took part in the same intensive, interdisciplinary, inpatient behavioral treatment approach. METHODS: Self-report measures were completed by 47 adolescent patients (mean age = 15.9) around 1 year or more from discharge from our inpatient program. Measures indexed changes in rumination, medical outcomes (eg, use of supplemental nutrition), somatic symptoms, and quality of life. RESULTS: Most patients reported continued improvement in their rumination over time, with 20% reporting cessation of rumination for at least 6 months. The majority of patients no longer required supplemental nutrition and reported improvements in somatic symptoms and quality of life. Patients who reported greater improvement in rumination also reported more significant improvements in their somatic symptoms and quality of life. CONCLUSIONS: Intensive behavioral treatment of rumination syndrome leads to long-term improvement in rumination as well as other related factors, including somatic symptoms and quality of life.

[Rumination syndrome: Diagnostic and therapeutic difficulties of a not so uncommon disorder]. / Síndrome de rumiación: dificultades diagnósticas y terapéuticas de un proceso no tan infrecuente.

INTRODUCTION: Rumination syndrome is an uncommon gastrointestinal functional disorder that may be difficult to diagnose, as not many physicians are aware of this condition. In many cases, patients undergo numerous tests and are prescribed several treatments based on erroneous diagnoses. When the correct diagnosis is eventually made, therapy for the syndrome can be difficult and complex because of its multifactorial nature. The aim of this study was to present our experience with this condition, by presenting an analysis of the clinical, diagnostic, and therapeutic data of our patients. PATIENTS AND METHOD: A prospective and retrospective study was conducted on all cases of rumination syndrome diagnosed between January 2010 and May 2016 in patients attending the Paediatric Gastroenterology Departments of two hospitals: Consorci Sanitari de Terrassa and Hospital Materno-Infantil Vall d'Hebron (Barcelona, Spain). RESULTS: The analysis included 12 patients, with a mean age at the onset of symptoms of 9 years and 1 month, and the mean time period to make the diagnosis was 2 years and 3 months. A mean of 8.1 complementary tests were carried out before establishing the diagnosis. In 10 of the 12 patients, some type of treatment had been given before the diagnosis of rumination syndrome, but was unsuccessful in all cases. Ten of our patients underwent the novel, experimental biofeedback therapy. CONCLUSIONS: Due to the limited knowledge of this condition among attending professionals in terms of the clinical presentation, diagnosis, and treatment, patients with rumination syndrome are often misdiagnosed and undergo numerous avoidable complementary tests, and invasive, costly treatments.

[Rumination].

Rumination syndrome is one of the functional gastroduodenal disorders. Effortless and repetitive regurgitation of recently ingested food from the stomach to the oral cavity followed by rechewing and reswallowing or spitting are the characteristic clinical features. This disorder is believed to be uncommon, but many patients with this disorder are overlooked by their physicians. Rumination might be caused by a reversal of the gastric contents through the esophagogastric junction, which is initiated by an increase in intragastric pressure. The characteristic symptoms are sufficient for the diagnosis of rumination syndrome. Postprandial high resolution esophageal impedance manometry can detect gastric pressurization exceeding 30 mmHg associated with the return of ingested material into the proximal esophagus, which is a pathognomonic finding of rumination syndrome. An extensive explanation of the condition and the underlying mechanism is the first step of the treatment of rumination syndrome. Behavioral therapy through diaphragmatic breathing is the mainstay of treatment. Further studies on the long term effects of biofeedback therapy as well as a proper strategy for refractory rumination syndrome are needed.

High-resolution Esophageal Manometry Patterns in Children and Adolescents With Rumination Syndrome.

BACKGROUND: Rumination is defined by effortless regurgitation within seconds or minutes of ingested food. The aim of this study was to determine the high-resolution esophageal manometry (HREM) pattern in children with rumination syndrome. METHODS: HREM was evaluated in 15 pediatric patients with rumination syndrome according to the Rome criteria and compared with 15 controls. Primary rumination was defined as a clinical rumination episode associated with a rise of gastric pressure above 30 mmHg. Secondary rumination was defined as a clinical rumination episode associated with a rise of gastric pressure above 30 mmHg during a transient lower esophageal sphincter relaxation (TLESR). RESULTS: Ninety-two episodes of rumination were demonstrated during HREM study in 12 of the 15 patients (80%; 1-29 episodes per patient; median intragastric pressure 49.6 mmHg). Primary rumination occurred in 3 patients and secondary rumination in 5 patients. One patient had primary and secondary rumination episodes. In 3 patients, classification of rumination episodes was not possible due to repetitive swallowing leading to lower esophageal sphincter relaxation. In the control group, no episodes of rumination occurred. The sensitivity and the specificity of the HREM study (association of a clinical rumination episode with a rise in gastric pressure >30 mmHg) to confirm the diagnosis of rumination were 80% and 100%, respectively. CONCLUSIONS: HREM allows confirming diagnosis of rumination syndrome and to differentiate between primary and secondary rumination in the presence of objective rumination episodes. Further research is needed to study whether HREM results may influence treatment and outcome of children with rumination syndrome.

The association between infantile postural asymmetry and unsettled behaviour in babies.

Unsettled infant behaviour is a common problem of infancy without known aetiology or clearly effective management. Some manual therapists propose that musculoskeletal dysfunction contributes to unsettled infant behaviour, yet reported improvement following treatment is anecdotal. The infantile postural asymmetry measurement scale is a tool which measures infantile asymmetry, a form of musculoskeletal dysfunction. The first part of the study aimed to investigate its reliability and validity for measuring infantile postural asymmetry. This study also aimed to investigate whether there was an association between infantile postural asymmetry and unsettled infant behaviour and whether an association was mediated by, or confounded with, the demographic variables of age, sex, parity, birth weight and weight gain in 12- to 16-week-old infants. Fifty-eight infants were recruited and a quantitative cross-sectional observational design was used. An association between unsettled behaviour and infantile postural asymmetry was not found. A significant difference between high and low cervical rotation deficit groups for surgency was detected in female babies and needs further examination. CONCLUSION: Questions remain regarding the construct validity of the infantile postural asymmetry scale. No association between unsettled infant behaviour and infantile postural asymmetry was found in 12- to 16-week-old infants. The influence of sex on the interaction between infantile postural asymmetry and infant behaviour needs further examination. An association between unsettled infant behaviour and infantile postural asymmetry is still unproven. What is known: • Unsettled infant behaviour has a considerable impact on many family situations. • Identifying a definitive cause has been a source of much examination and research. Many different hypotheses have been suggested yet much is still unknown. What is new: • The association between unsettled infant behaviour and infantile postural asymmetry is still unproven. • The need to validate a reliable tool to measure infantile postural asymmetry, with particular focus on cervical spine rotation deficit, is indicated.
