[Ab] Resumo:BACKGROUND: Little is known about mother-child feeding interactions and how this is associated with food intake and linear growth. OBJECTIVE: To characterize mother-child feeding styles and investigate their associations with accepted mouthful and linear growth in west Gojam, rural Ethiopia. SUBJECTS/DESIGN: Two, in-home, meal observations of children aged 12-23 months (n = 100) were video-taped. The number of mouthful accepted was counted and the caregiver/child feeding styles were coded into positive/negative categories of self-feeding, responsive-feeding, active-feeding, social-behavior and distraction. Data on socio-demographic characteristics, child feeding practices, perception about child's overall appetite, and strategies adopted to overcome food refusal were collected through questionnaire-based interviews. Child and mothers' anthropometric measurements were also taken. RESULTS: Stunting was highly prevalent (48%) and the number of mouthful accepted was very low. Offering breastmilk and threatening to harm were the main strategies adopted to overcome food refusal. Although all forms of feeding style were present, active positive feeding style was dominant (90%) and was positively associated with mouthful accepted. Talking with non-feeding partner (64%), and domestic animals (24%) surrounding the feeding place were common distractions of feeding. Feeding was mostly terminated by caregivers (75%), often prematurely. Overall, caregivers of stunted children had poorer complementary- and breast-feeding practices and were less responsive to child's hunger and satiation cues (P < 0.05). Positive responsive feeding behaviors were associated with child's number of mouthful accepted (r = 0.27; P = 0.007) and stunting (r = 0.4; P < 0.001). CONCLUSION: Low complementary food intake in this setting is associated with caregivers' feeding style and stunting. Nutrition interventions that reinforce messages of optimal infant and young child feeding and integrate the promotion of responsive feeding behaviors are needed.

[Ab] Resumo: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.

[Ab] Resumo:OBJECTIVE: To document the use of diagnostic testing in adolescents who ultimately were diagnosed with rumination syndrome, a functional gastrointestinal disorder. We examined the diagnostic yield of each test as well as the associated costs, and we determined if any demographic or illness-related variables impacted the magnitude of the work-up. STUDY DESIGN: A retrospective chart review was conducted for 68 patients with rumination syndrome admitted to our inpatient treatment program. The cost and findings of patients' diagnostic investigations were gathered, as well as demographic and illness-related variables to determine factors that may be related to evaluation size. RESULTS: The most commonly used tests in the evaluation of rumination syndrome included esophagogastroduodenoscopy, gastric emptying, antroduodenal manometry, upper gastrointestinal series, and abdominal ultrasound scan. Each patient underwent an average of 8.8 tests, with the average cost for each patient's diagnostic work-up being US $19 795. Few tests were found to be beneficial in the diagnosis of rumination syndrome, and few demographic or illness variables were found to be related to the overall extent of the investigation. CONCLUSIONS: Extensive testing for rumination syndrome in adolescents is common in clinical practice, and comes at a high financial cost with low yield, likely delaying diagnosis and treatment. Symptom-based criteria should be used to make the diagnosis of rumination syndrome.

[Ti] Título:Objectively diagnosing rumination syndrome in children using esophageal pH-impedance and manometry.

[La] Idioma:eng
[Ab] Resumo:BACKGROUND: Rumination syndrome is characterized by recurrent regurgitation of recently ingested food into the mouth. Differentiation with other diagnoses and gastroesophageal reflux disease (GERD) in particular, is difficult. Recently, objective pH-impedance (pH-MII) and manometry criteria were proposed for adults. The aim of this study was to determine diagnostic ambulatory pH-MII and manometry criteria for rumination syndrome in children. METHODS: Clinical data and 24-hour pH-MII and manometry recordings of children with a clinical suspicion of rumination syndrome were reviewed. Recordings were analyzed for retrograde bolus flow extending into the proximal esophagus. Peak gastric and intraesophageal pressures closely related to these events were recorded and checked for a pattern compatible with rumination. Events were classified into primary, secondary, and supragastric belch-associated rumination. KEY RESULTS: Twenty-five consecutive patients (11 males, median age 13.3 years [IQR 5.9-15.8]) were included; recordings of 18 patients were suitable for analysis. Rumination events were identified in 16/18 patients, with 50% of events occurring <30 minutes postprandially. Fifteen of 16 patients showed ≥1 gastric pressure peak >30 mmHg, while only 50% of all events was characterized by peaks >30 mmHg and an additional 20% by peaks >25 mmHg. Four patients had evidence of acid GERD, all showing secondary rumination. CONCLUSIONS AND INFERENCES: Combined 24-hour pH-MII and manometry can be used to diagnose rumination syndrome in children and to distinguish it from GERD. Rumination patterns in children are similar compared with adults, albeit with lower gastric pressure increase. We propose a diagnostic cutoff for gastric pressure increase >25 mmHg associated with retrograde bolus flow into the proximal esophagus.

[Ab] Resumo:BACKGROUND: The differential diagnosis of intractable reflux in children includes rumination syndrome, but confirming the diagnosis using antroduodenal manometry is invasive, is costly, and requires anesthesia. High-resolution esophageal manometry with impedance (HRM-MII) overcomes these limitations, and the goal of this study is to validate the use of HRM-MII as a diagnostic tool for rumination and to describe the subtypes of pediatric rumination. METHODS: We reviewed the HRM-MII tracings of 21 children presenting with symptoms of intractable reflux in whom rumination was being considered. Patients underwent a standard and post-prandial HRM-MII. Peak intraluminal esophageal pressures, baseline gastric and thoracic pressures, and the timing of the R wave relative to LES relaxations and bolus flow were recorded. Chi-square analyses were used for comparison of proportions and means were compared using t-tests or non-parametric equivalent. KEY RESULTS: Forty-one (55.5%) primary and 33 (44.5%) secondary rumination episodes were seen. Three types of primary rumination were identified: i) LES relaxation without retrograde flow preceding the R wave (51% of episodes); ii) LES relaxation after the R wave (20% of episodes); and iii) R waves with no LES relaxation (29% of episodes). Eleven patients had rumination episodes with a peak gastric pressure <30 mm Hg. A total of 44 (60%) rumination episodes occurred during the standard HRM-MII, and 30 (40%) occurred during or after the meal. CONCLUSIONS & INFERENCES: HRM-MII can accurately diagnose rumination in children. We identify three types of primary rumination which may provide insight into therapeutic response.

[Ab] Resumo:BACKGROUND AND OBJECTIVES: According to cognitive models of Social Anxiety Disorder (SAD), negative rumination is a key maintaining factor in the vicious cycle of social anxiety. However, there is a scarcity of research investigating treatment effects on rumination in social anxiety, as well as other key cognitive variables. The current study aimed to determine the effectiveness of a brief intervention on a range of cognitive processes, most notably negative rumination. Additionally, predictors of negative rumination and state anxiety are also investigated. METHODS: Participants with a diagnosis of SAD were randomly allocated to an intervention (n = 24) or control group (n = 23). Participant's initially completed trait and state based measures with the intervention group also completing a brief cognitive intervention. One-week later participants completed state anxiety and cognitive measures before and after a speech task. Finally, one-week post-speech task participants completed further trait and state based measures. RESULTS: While the brief cognitive intervention had positive effects on some of the cognitive processes measured at different time points of the study, levels of negative rumination remained stable. Predictors of negative rumination and state anxiety were consistent with cognitive models of SAD. LIMITATIONS: The brief nature of the intervention and temporal stance of the intervention (delivered one-week before the speech) may have impacted outcomes. CONCLUSIONS: Cognitive technique can potentially impact a range of key processes that maintain SAD, however, more powerful and tailored interventions are needed that address the different processes at play before, during and after a social situation for socially anxious individuals.

[Ab] Resumo:The essential adaptive food selection behavior of young children has become increasingly medicalized as a kind of disease-the "picky-eating" syndrome in Hong Kong. The researcher used the multiple case studies approach with data collected from in-depth interviews and advertisements to examine the process of the medicalization of picky-eating disorder, which demonstrates how an essential adaptive human behavior can be redefined by the market and medical system as a deviant, abnormal behavior that needs to be eliminated and how the resulting health risks can be resolved by modern medicine produced by this pharmaceutical nexus.

[Ab] Resumo:This study aimed to develop a scale called Tongue Thrust Rating Scale (TTRS), which categorised tongue thrust in children in terms of its severity during swallowing, and to investigate its validity and reliability. The study describes the developmental phase of the TTRS and presented its content and criterion-based validity and interobserver and intra-observer reliability. For content validation, seven experts assessed the steps in the scale over two Delphi rounds. Two physical therapists evaluated videos of 50 children with cerebral palsy (mean age, 57·9 ± 16·8 months), using the TTRS to test criterion-based validity, interobserver and intra-observer reliability. The Karaduman Chewing Performance Scale (KCPS) and Drooling Severity and Frequency Scale (DSFS) were used for criterion-based validity. All the TTRS steps were deemed necessary. The content validity index was 0·857. A very strong positive correlation was found between two examinations by one physical therapist, which indicated intra-observer reliability (r = 0·938, P < 0·001). A very strong positive correlation was also found between the TTRS scores of two physical therapists, indicating interobserver reliability (r = 0·892, P < 0·001). There was also a strong positive correlation between the TTRS and KCPS (r = 0·724, P < 0·001) and a very strong positive correlation between the TTRS scores and DSFS (r = 0·822 and r = 0·755; P < 0·001). These results demonstrated the criterion-based validity of the TTRS. The TTRS is a valid, reliable and clinically easy-to-use functional instrument to document the severity of tongue thrust in children.

[Ti] Título:Pain-Related Rumination, But Not Magnification or Helplessness, Mediates Race and Sex Differences in Experimental Pain.

[Ab] Resumo:Compared with white individuals and men, black individuals and women show a lower tolerance for experimental pain stimuli. Previous studies suggest that pain catastrophizing is important in this context, but little is known about which components of catastrophizing contribute to these race and sex differences. The purpose of the current study was to examine the individual components of catastrophizing (rumination, magnification, and helplessness) as candidate mediators of race and sex differences in experimental pain tolerance. Healthy undergraduates (N = 172, 74% female, 43.2% black) participated in a cold pressor task and completed a situation-specific version of the Pain Catastrophizing Scale. Black and female participants showed a lower pain tolerance than white (P < .01, d = .70) and male (P < .01, d = .55) participants, respectively. Multiple mediation analyses indicated that these race and sex differences were mediated by the rumination component of catastrophizing (indirect effect = -7.13, 95% confidence interval (CI), -16.20 to -1.96, and 5.75, 95% CI, .81-15.57, respectively) but not by the magnification (95% CI, -2.91 to 3.65 and -1.54 to 1.85, respectively) or helplessness (95% CI, -5.53 to 3.31 and -.72 to 5.38, respectively) components. This study provides new information about race and sex differences in pain and suggests that treatments targeting the rumination component of catastrophizing may help mitigate pain-related disparities. PERSPECTIVE: This study suggests that differences in pain-related rumination, but not magnification or helplessness, are important contributors to race and sex differences in the pain experience. Interventions that target this maladaptive cognitive style may help reduce disparities in pain.
