    We examined the efficacy of a tailored education program using touch-screen computers for caregivers of young children with asthma, aged 0 to 6 years. Fifty-three caregivers (mean age, 36.54 years; 51 mothers and two fathers) were recruited during typical visits to a national children's hospital. Caregivers were assigned randomly to 28 in the tailored education or 25 in the booklet education groups. The tailored education group received messages generated by a computer program, and the researchers provided them with counseling. The booklet education group only received an educational booklet. The primary outcome variable was parental self-efficacy and its subscales (ie, medication behavior, environmental behavior, barriers to self-management, and consultation behavior). The tailored education group showed an increase in barriers to management and asthma knowledge compared with the booklet education group. Over time, caregivers' quality of life improved significantly in both groups. Tailored education programs for caregivers of asthmatic children require further educational content modifications to match the learners' characteristics more closely. This study supports the notion that the development of patient education with tailored computer programs improves parental quality of life of asthma.

    Background Most physical activity and nutrition interventions in children focus on the school setting; however, evidence suggests that children are less active and have greater access to unhealthy food at home. The aim of this pilot study was to examine the efficacy of a compulsory homework programme for increasing physical activity and healthy eating in children. Methods The six-week 'Healthy Homework' programme and complementary teaching resource was developed under the guidance of an intersectoral steering group. Eight senior classes (year levels 5-6) from two diverse Auckland primary schools were randomly assigned into intervention and control groups. A total of 97 children (57 intervention, 40 control) aged 9-11 years participated in the evaluation of the intervention. Daily step counts were monitored immediately before and after the intervention using sealed multiday memory pedometers. Screen time, sports participation, active transport to and from school, and the consumption of fruits, vegetables, unhealthy foods and drinks were recorded concurrently in a 4-day food and activity diary. Results Healthy Homework resulted in a significant intervention effect of 2,830 steps.day-1 (95% CI: 560, 5,300, P = 0.013). This effect was consistent between sexes, schools, and day types (weekdays and weekend days). In addition, significant intervention effects were observed for vegetable consumption (0.83 servings.day-1, 95% CI: 0.24, 1.43, P = 0.007) and unhealthy food consumption (-0.56 servings.day-1, 95% CI: -1.05, -0.07, P = 0.027) on weekends but not weekdays, with no interactions with sex or school. Effects for all other variables were not statistically significant regardless of day type. Conclusions Compulsory health-related homework appears to be an effective approach for increasing physical activity and improving vegetable and unhealthy food consumption in children. Further research in a larger study is required to confirm these initial results. PMID:22085440

    This study was a trial of an intervention programme aimed to improve parental self-efficacy in the management of problem behaviours associated with Asperger syndrome. The intervention was compared across two formats, a 1 day workshop and six individual sessions, and also with a non-intervention control group. The results indicated that, compared with the control group, parents in both intervention groups reported fewer problem behaviours and increased self-efficacy following the interventions, at both 4 weeks and 3 months follow-up. The results also showed a difference in self-efficacy between mothers and fathers, with mothers reporting a significantly greater increase in self-efficacy following intervention than fathers. There was no significant difference between the workshop format and the individual sessions.

    Project ImPACT is a Naturalistic Developmental Behavioral Intervention (NDBI) for young children with ASD. Preliminary research supports its feasibility and efficacy as a parent-mediated intervention; however, its efficacy as a low-intensity, therapist-implemented intervention is unclear. A single-case, multiple-baseline design evaluated the effect of 2 h per week of therapist-implemented Project ImPACT on social engagement, language, and play in nine children with ASD. Language and play skills were targeted separately for five children and together for four children. Children increased their rates of social engagement and language when language or play was the sole target and when language and play were targeted together; however, gains in play skills were evident only when they were targeted separately. This study provides support for the efficacy of the Project ImPACT when implemented by therapists at a low intensity and suggests the way in which skills are targeted can affect child learning.

    Primary hypertension is a growing concern in children because of the obesity epidemic largely attributable to western lifestyles. Serum uric acid is known to be influenced by dietary habits, correlates with obesity, and could represent a risk factor for hypertension. Preliminary studies in children highlighted uric acid as a potentially modifiable risk factor for the prevention and treatment of hypertension. The effect of lifestyle changes (increase of physical activity and dietary modifications) on blood pressure values, weight status, and serum uric acid levels in a cohort of 248 children referred for cardiovascular risk assessment were evaluated over a mean 1.5-year follow-up. At baseline, 48% of children were obese and 50% showed blood pressure values >90th percentile. At follow-up, a significant improvement in weight class (24% obese;P<0.0001) and blood pressure category (22% >90th percentile;P<0.0001) was found. Systolic blood pressure z-score (P<0.0001), uric acid value (P=0.0056), and puberty at baseline (P=0.0048) were independently associated with higher systolic blood pressure z-score at follow-up, whereas a negative association was observed with body mass index z-score decrease during follow-up (P=0.0033). The risk of hypertension at follow-up was associated with body mass index (P=0.0025) and systolic blood pressure (P<0.0001) z-score at baseline and inversely related to delta body mass index (P=0.0002), whereas the risk of showing hypertension ≥99th percentile was more than doubled for each baseline 1 mg/dL increase of serum uric acid (P=0.0130). Uric acid is a powerful determinant of blood pressure over time, independent of lifestyle modifications.

  9. Does Engaging in a Group-Based Intervention Increase Parental Self-efficacy in Parents of Preschool Children? A Systematic Review of the Current Literature.

    As the preschool years are a formative period for long-term physical and mental health, this period is recognised as an important window for early effective intervention. Parenting behaviour is a key factor to target in order to optimise child development. Group-based interventions for parents are considered efficient and cost effective methods of early intervention and have been found to improve child behaviour and adjustment. Self-efficacy is key to behaviour change and as such parental self-efficacy should be a consideration in interventions aimed at influencing parenting behaviour. Therefore, the purpose of this systematic review was to examine the impact of group-based early interventions for parents of preschool children on parental self-efficacy. Nine databases were searched (ASSIA, CINAHL, EMBASE, Maternity and Infant Care, Ovid Medline, PsycINFO, Pubmed, Science Direct and Web of Science). Studies were included if they were a randomised controlled trial of a group-based intervention for parents of preschool children and measured change in parental self-efficacy. Fifteen studies were identified. Although changes in parental self-efficacy following a group-based intervention were noted in the majority of studies reviewed, the methodological quality of the studies included in the review means these findings have to be interpreted with caution; only seven studies were rated to be methodologically adequate. Further research is needed to understand the mechanisms by which these interventions may improve parental self-efficacy. Studies specifically examining the impact of such interventions on paternal self-efficacy are also warranted.

    The aim of this article was to investigate the use of exergaming in promoting exercise behavior among children and to examine the impact of the intervention on participants’ exercise self-efficacy, in addition to assessing physiological changes. A sample of 55 children enrolled in the Family Fit program, where participants were categorized into 2 groups: healthy weight and overweight. Measures were taken at baseline, after the 7-week program, at the 12-week follow-up, and at the 24-month follow-up. Positive changes in exercise self-efficacy were significant for the overweight group, while the healthy weight group maintained their exercise self-efficacy. At the 24-month follow-up, 97% children reported being interested in participating in a future fitness program, and 96% children who did not play sports before the intervention started practicing sports. Exercise self-efficacy is a predictor of physical activity, and incorporating exergaming in a structured program may lead to increased self-efficacy in participants. PMID:27336015

    The efficacy of eye movement desensitization and reprocessing (EMDR) in children with post-traumatic stress symptoms was meta-analytically examined from the perspective of incremental efficacy. Overall post-treatment effect size for EMDR was medium and significant (d=.56). Results indicate efficacy of EMDR when effect sizes are based on comparisons between the EMDR and the non-established trauma treatment or the no-treatment control groups, and the incremental efficacy when effect sizes are based on comparisons between the EMDR and the established (CBT) trauma treatment. The discussion focuses on the future replication of EMDR findings and further research on post-traumatic stress in children.

    2015-03-01

    Increased body weight is associated with decreased cognitive function in school-aged children. The role of self-efficacy in shaping the connection between children's educational achievement and obesity-related comorbidities has not been examined to date. Evidence of the predictive ability of self-efficacy in children is demonstrated in cognitive tasks, including math achievement scores. This study examined the relationship between self-efficacy and math achievement in normal weight, overweight, and obese children. I hypothesized that overweight and obese children with higher self-efficacy will be less affected in math achievement than otherwise comparable children with lower self-efficacy. I tested this prediction with multilevel growth modeling techniques using the ECLS-K 1998-1999 survey data, a nationally representative sample of children. Increased self-efficacy moderates the link between body weight and children's math achievement by buffering the risks that increased weight status poses to children's cognitive function. My findings indicate that self-efficacy moderates math outcomes in overweight, but not obese, children.

    Objectives The association between changes in clinician self-efficacy and readiness to change and implementation of an asthma management program (Easy Breathing©) was examined. Methods A 36 month randomized, controlled trial was conducted involving 24 pediatric practices (88 clinicians). Randomized clinicians received interventions designed to enhance clinician self-efficacy and readiness to change which were measured at baseline and 3 years. Interventions consisted of an educational toolbox, seminars, teleconferences, mini-fellowships, opinion leader visits, clinician-specific feedback, and pay for performance. The primary outcome was program utilization (number of children enrolled in Easy Breathing/year); secondary outcomes included development of a written treatment plan and severity-appropriate therapy. Results At baseline, clinicians enrolled 149 ± 147 (mean ± SD) children/clinician/year; 84% of children had a written treatment plan and 77% of plans used severity-appropriate therapy. At baseline, higher self-efficacy scores were associated with greater program utilization (Relative Rate (RR) 1.34 (95% Confidence Interval 1.04, 1.72), p=0.04) but not treatment plan development (RR 0.63 (0.29, 1.35), p=.23) or anti-inflammatory use (RR 1.76 (0.92, 3.35), p=.09). Intervention clinicians participated in 17 interventions over 36 months. At study end, self-efficacy scores increased in intervention clinicians compared to control clinicians (p=0.01) and more clinicians were in an action stage of change (p=0.001) but these changes were not associated with changes in primary or secondary outcomes. Conclusions Self-efficacy scores correlated with program use at baseline and increased in the intervention arm but these increases were not associated with greater program-related activities. Self-efficacy may be necessary but not sufficient for behavior change. PMID:22634077

    Gynecologic applications of optical coherence tomography (OCT) are usually performed in combination with routine diagnostic procedures: laparoscopy and colposcopy. In combination with laparoscopy OCT is employed for inspection of fallopian tubes in cases of unrecognized infertility while in colposcopy it is used to identify cervix pathologies including cancer. In this paper we discuss methods for increasing diagnostic efficacy of OCT application in these procedures. For OCT-laparoscopy we demonstrate independent criteria for pathology recognition which allow to increase accuracy of diagnostics. For OCT-colposcopy we report on application of device for controlled compression allowing to sense the elasticity of the inspected cervix area and distinguish between neoplasia and inflammatory processes.

    Preterm birth often results in significant learning disability, and previous magnetic resonance imaging (MRI) studies of preterm children have demonstrated reduction in overall cortical tissue with particular vulnerability in the temporal lobe. We measured cortical gyrification in 73 preterm and 33 term control children at 8 years of age and correlated these findings with tests of language ability to determine the associations among preterm birth, neurodevelopment and functional outcome. Preterm children demonstrated significantly increased bilateral temporal lobe gyrification index compared to term controls. Left temporal gyrification index was significantly negatively correlated with left temporal lobe gray matter volume as well as reading recognition scores in the preterm group. Cortical development in the temporal lobe appears to be differentially vulnerable to preterm birth.

  5. [Increased efficacy of radiation protection against fission neutrons using unithiol].

    1999-01-01

    It was found that the combination of unithiol (Sodium salt of 2,3-dimercapto-1-propansulfonic acid) with cystamine and AET diminished their toxicity. The optimum ratio for the antitoxic effect is 0.5 molar equivalent of unithiol per radioprotective 1.0 equivalent of thiol. Animals withstand big doses of protectors well, that gives an opportunity to use increased amounts of cystamine and AET. In the experiments with circular irradiation of male (CBA x C57B1)F1 mice weighing 18-22 g with fission neutrons (the neutron mean energy was 0.85 MeV, the contribution of gamma-quanta to the total was 25%, dose rate was 14 cGy/min) it was shown that the combination of unithiol with cystamine and AET enhances their radioprotective effect: the DRF of cystamine (150 mg/kg)--1.1, and the DRF of the combination of cystamine (300 mg/kg) with unithiol (152 mg/kg)--1.2; the DRF of AET (150 mg/kg)--1.2, the DRF of the combination of AET (300 mg/kg) with unithiol--1.4. Thus, the enhancement of dose of the radioprotectors, which was made possible as a result of their combination with unithiol, leads to enhancement of efficacy of chemical protection against fission neutron irradiation as much as 10-20%. Efficacy of AET is found to be comparable to efficacy of this protector in conditions of X-rays irradiation.

    Carr, Kayleigh; Kendal, Rachel L; Flynn, Emma G

    2015-09-01

    This study investigated the age at which children judge it futile to imitate unreliable information, in the form of a visibly ineffective demonstrated solution, and deviate to produce novel solutions ('innovations'). Children aged 4-9 years were presented with a novel puzzle box, the Multiple-Methods Box (MMB), which offered multiple innovation opportunities to extract a reward using different tools, access points and exits. 209 children were assigned to conditions in which eight social demonstrations of a reward retrieval method were provided; each condition differed incrementally in terms of the method's efficacy (0%, 25%, 75%, and 100% success at extracting the reward). An additional 47 children were assigned to a no-demonstration control condition. Innovative reward extractions from the MMB increased with decreasing efficacy of the demonstrated method. However, imitation remained a widely used strategy irrespective of the efficacy of the method being reproduced (90% of children produced at least one imitative attempt, and imitated on an average of 4.9 out of 8 attempt trials). Children were more likely to innovate in relation to the tool than exit, even though the latter would have been more effective. Overall, innovation was rare: only 12.4% of children innovated by discovering at least one novel reward exit. Children's prioritisation of social information is consistent with theories of cultural evolution indicating imitation is a prepotent response following observation of behaviour, and that innovation is a rarity; so much so, that even maladaptive behaviour is copied.

    1984-06-01

    This paper reviews studies that have examined the efficacy of relaxation training techniques in the treatment of childhood disorders. Methodological problems encountered in doing research in this area resemble those found in working with an adult population: imprecise definitions of subject populations and use of a variety of dependent variables from one study to another. Findings suggest that relaxation training is at least as effective as other treatment approaches for a variety of learning, behavioral, and physiological disorders when it is continued over an extended period of time and is augmented by other supportive measures. Needs for future research include better follow-up studies and further investigations with a behaviorally disruptive population.

    Vancomycin susceptibility of methicillin-resistant Staphylococcus aureus has been changed over time and its average minimum inhibitory concentration increased from 1.5 to 1.75 mg/L.A recently published guideline by the American Society of Health Pharmacist recommended a daily dose of 15-20 mg/Kg every 8 to 12 hours of vancomycin to achieve a trough concentration between 15-20 mg/L for treatment of severe infections. Medical records of 69 patients from infectious ward of Imam Khomeini hospital, with suspected or confirmed gram-positive infection who had at least one trough level of vancomycin, were evaluated regarding vancomycin therapeutic goal; efficacy and renal safety. Most of patients (60.6%) with severe infections did not achieve the recommended vancomycin trough level during treatment course. Time to normalization of the signs and symptoms of infection did not correlate with the patients’ serum vancomycin trough levels. At the end of treatment course, there was no significant correlation between patients’ creatinine clearance and vancomycin trough levels (P=0.32). However, patients’cratinine clearance showed a negatively significant correlation with trough level of vancomycin (P=0.01). Vancomycin induced nephrotoxicity was detected in 4.3% of the patients. These data showed that vancomycin trough level may not necessarily assure treatment success, and also it would not essentially predict the risk of vancomycin induced nephrotoxicity. However, more well designed studies with larger sample size needed for better clinical and practical judgment. PMID:25587313

  11. Does pregnancy increase the efficacy of lumbar epidural anesthesia?

    PubMed

    Arakawa, M

    2004-04-01

    Pregnancy has been reported to enhance the sensitivity of nerves to local anesthetics and to decrease anesthetic requirements during regional anesthesia. In this study, whether pregnancy increased the efficacy of lumbar epidural anesthesia was evaluated. Two populations (14 pregnant and 14 non-pregnant women) undergoing lumbar epidural anesthesia were studied and received 17 mL of 2% lidocaine-epinephrine (1: 200,000). The pain threshold response after repeated electrical stimulation was used to assess sensory blockade at the L2, S1 and S3 dermatomes. Motor blockade was evaluated using the Bromage score. Demographic data except for weight were comparable between the two groups. There was a significant difference in cephalad spread of anesthesia between the groups. No significant differences in pain threshold or onset of sensory blockade at the L2, S1 or S3 segments were found between the groups. The pain thresholds at the S1 and S3 dermatomes were significantly lower than that at L2 within each group. The mean onset times at the S1 and S3 dermatomes were significantly longer than that at L2 within each group. No differences in Bromage score were found between the groups. In pregnant women, cephalad spread of epidural anesthesia was facilitated but latency of blockade, density and motor blockade were not. It takes over 25 min to achieve satisfactory blockade at sacral segments. Those who perform lumbar epidural anesthesia alone for cesarean section should consider the use of additives (e.g. fentanyl, bicarbonate) to enhance the block, or a greater volume of local anesthetic.

    Early preventive dental visits are vital to the oral health of children. Yet many children, especially preschool-age children enrolled in Medicaid, do not receive early visits. This study attempts to uncover factors that can be used to encourage parents to seek preventive dental care for preschool-age children enrolled in Medicaid. The extended parallel process model was used as a theoretical framework for this research. This model suggests that people will act if the perceived threat (severity and susceptibility) is high enough and if efficacy levels (self-efficacy and response efficacy) are likewise high. Following Witte's method of categorizing people's perceptions and emotions into one of four categories based on levels of threat and efficacy, this article describes four groups (high threat/high efficacy, high threat/low efficacy, low threat/high efficacy, and low threat/low efficacy) of parents and how they compare to each other. Using logistic regression to model if a child had a preventive visit, results indicate that parents with low threat/high efficacy and parents with high threat/high efficacy had approximately 2.5 times the odds of having a child with a preventive oral health visit compared to parents with low threat/low efficacy, when controlling for perceived oral health status, health literacy, and child's age. The importance of efficacy needs to be incorporated in interventions aimed at increasing preventive dental visits for young children.

    Children with feeding disorders often do not self-drink without treatment. Unfortunately, the literature on self-drinking is scarce. We evaluated differential positive reinforcement to increase self-drinking for 2 children with feeding disorders. Results showed that differential positive reinforcement with tangible items increased self-drinking for both children in the absence of nonremoval of the cup.

    2001-01-01

    This prospective study tested with 272 children a structural model of the network of sociocognitive influences that shape children's career aspirations and trajectories. Familial socioeconomic status is linked to children's career trajectories only indirectly through its effects on parents' perceived efficacy and academic aspirations. The impact of parental self-efficacy and aspirations on their children's perceived career efficacy and choice is, in turn, entirely mediated through the children's perceived efficacy and academic aspirations. Children's perceived academic, social, and self-regulatory efficacy influence the types of occupational activities for which they judge themselves to be efficacious both directly and through their impact on academic aspirations. Perceived occupational self-efficacy gives direction to the kinds of career pursuits children seriously consider for their life's work and those they disfavor. Children's perceived efficacy rather than their actual academic achievement is the key determinant of their perceived occupational self-efficacy and preferred choice of worklife. Analyses of gender differences reveal that perceived occupational self-efficacy predicts traditionality of career choice.

    Objective: To investigate the clinical efficacy of tiotropium in children with asthma. Methods: Eighty children with newly diagnosed moderate persistent asthma were enrolled into this study. The children were randomly assigned to the fluticasone propionate aerosol group or the fluticasone propionate aerosol plus tiotropium group for 12 weeks. Results: Lung function was significantly improved in both groups at 4, 8, and 12 weeks compared with baseline (P < 0.01). Moreover, lung function was significantly improved in the tiotropium group compared with the control group (P < 0.05). However, there was no significant difference in the incidence of severe asthma between the two groups (36.3% and 26.8%, respectively; P > 0.05). Compared with the control group, the number of days and frequency of short-acting beta2-adrenoceptor agonist use was significantly reduced in the tiotropium group (P < 0.05). Awakenings during the night were also significantly decreased (P < 0.00). There were no severe adverse reactions in either of the study groups. Conclusion: Tiotropium could significantly improve lung function, reduce the use of short-acting beta2-adrenoceptor agonists, and improve sleep in children with asthma. Furthermore, few adverse reactions were reported. PMID:27182262

    2015-08-01

    The development of associative memory during childhood may be influenced by metacognitive factors. Here, one aspect of metamemory function--belief in strategy efficacy-was tested for a role in the effective use of encoding strategies. A sample of 61 children and adults (8-25 years of age) completed an associative recognition memory test and were assessed on belief in the efficacy of encoding strategies. Independent of age, belief ratings identified two factors: "deep" and "shallow" encoding strategies. Although the strategy factor structure was stable across age, adolescents and adults were more likely to prefer using a deep encoding strategy, whereas children were equally likely to prefer a shallow strategy. Belief ratings of deep encoding strategies increased with age and, critically, accounted for better associative recognition.

    Evidence of high efficacy of live attenuated influenza vaccine (LAIV) from randomized controlled trials is strong for children 2-6 years of age, but fewer data exist for older school-age children. We reviewed the published data on efficacy and effectiveness of LAIV in children ≥5 years. QUOSA (Elsevier database) was searched for articles published from January 1990 to June 2014 that included 'FluMist', 'LAIV', 'CAIV', 'cold adapted influenza vaccine', 'live attenuated influenza vaccine', 'live attenuated cold adapted' or 'flu mist'. Studies evaluated included randomized controlled trials, effectiveness and indirect protection studies. This review demonstrates that LAIV has considerable efficacy and effectiveness in school-age children.

    ABSTRACT This work reports the results of an evaluation study to assess the efficacy of the Early HeartSmarts (EHS) program in schools of the Salt Lake City, Utah, School District. The EHS program is designed to guide teachers with methods that support young children (3–6 y old) in learning emotion self-regulation and key age-appropriate socioemotional competencies with the goal of facilitating their emotional, social, and cognitive development. The study was conducted over one school year using a quasiexperimental longitudinal field research design with 3 measurement points (baseline, preintervention, and postintervention) using The Creative Curriculum Assessment (TCCA), a teacher-scored, 50-item instrument measuring students growth in 4 areas of development: social/emotional, physical, cognitive, and language development. Children in 19 preschool classrooms in the Salt Lake City School District were divided into intervention and control group samples (n = 66 and n = 309, respectively; mean age = 3.6 y). The intervention classes were specifically selected to target children of lower socioeconomic and ethnic minority backgrounds. Overall, there is compelling evidence of the efficacy of the EHS program in increasing total psychosocial development and each of the 4 development areas measured by the TCCA: the results of a series of analyses of covariance found a strong, consistent pattern of large, significant differences on the development measures favoring preschool children who received the EHS program over those in the control group.

    In the chemical world, evolution is mirrored in the origin of nanoscale supramolecular structures from molecular subunits. The complexity of function acquired in a supramolecular system over a molecular subunit can be harnessed in the treatment of cancer. However, the design of supramolecular nanostructures is hindered by a limited atomistic level understanding of interactions between building blocks. Here, we report the development of a computational algorithm, which we term Volvox after the first multicellular organism, that sequentially integrates quantum mechanical energy-state- and force-field-based models with large-scale all-atomistic explicit water molecular dynamics simulations to design stable nanoscale lipidic supramolecular structures. In one example, we demonstrate that Volvox enables the design of a nanoscale taxane supramolecular therapeutic. In another example, we demonstrate that Volvox can be extended to optimizing the ratio of excipients to form a stable nanoscale supramolecular therapeutic. The nanoscale taxane supramolecular therapeutic exerts greater antitumor efficacy than a clinically used taxane in vivo. Volvox can emerge as a powerful tool in the design of nanoscale supramolecular therapeutics for effective treatment of cancer.

    Physical activity in children has been associated with a number of health benefits. Unfortunately, physical inactivity continues to increase. The purpose of this study was to examine the relationships among self-efficacy levels, physical activity, aerobic fitness, and body composition (relative body mass index [RBMI]) and to determine whether a school-based pedometer intervention program would improve those variables. The sample consisted of 116 rural 11- to 13-year-old students. Weakly positive correlations between self-efficacy, physical activity, and aerobic fitness and weakly correlated inverse relationships between self-efficacy, physical activity, aerobic fitness and RBMI were found. There was no statistical significance between the intervention and control group when analyzing outcome variables. These findings suggest that those with optimal RBMI levels have higher self-efficacy, physical activity and aerobic fitness levels. Although not statistically significant, the intervention group had greater improvements in mean self-efficacy scores, aerobic fitness levels, and RBMI.

    Photokilling depends on the generation of death signals after photosensitized cells are irradiated. A variety of intracellular organelles can be targeted for photodamage, often with a high degree of specificity. We have discovered that a low level of photodamage directed against lysosomes can sensitize both a murine hepatoma cell line (in 2D culture) and an inflammatory breast cancer line of human origin (in a 3D model) to subsequent photodamage directed at mitochondria. Additional studies were carried out with hepatoma cells to explore possible mechanisms. The phototoxic effect of the `sequential targeting' approach was associated with an increased apoptotic response. The low level of lysosomal photodamage did not lead to any detectable migration of Fe++ from lysosomes to mitochondria or increased reactive oxygen species (ROS) formation after subsequent mitochondrial photodamage. Instead, there appears to be a signal generated that can amplify the pro-apoptotic effect of subsequent mitochondrial photodamage.

    Background Application of distractive forces to small bowel induces intestinal growth, or enterogenesis. This emerging area of research may provide treatment for short bowel syndrome (SBS). Glucagon-like peptide 2(GLP-2) has also been reported to induce small bowel growth after bowel resection. We hypothesized that exogenous GLP-2 will result in enhanced distraction-induced enterogenesis. Methods Distraction-induced model was performed in 10-week-old C57B6 mice using osmotic forces with high molecular weight polyethylene glycol (PEG-stretch). Four groups were studied: Control group (PEG−/GLP-2−); PEG-stretch (PEG+/GLP-2−); GLP-2 control (PEG−/GLP-2+); and GLP-2 stretch (PEG+/GLP-2+). GLP-2 was given via subcutaneous osmotic pump over the 5 days of experiment. Morphology was measured by histomicrography. Epithelial cell (EC) proliferation was measured with PCNA immunofluorescent staining. Total intestinal growth and blood vessel volume was assessed with Micro CT volumetry. VEGF, FGF1 and 2, and PDGF were measured by RT-PCR. Results EC proliferation increased significantly in all groups compared to Controls, but was greatest in the GLP-2 stretch group. Diameter and length significantly increased in the PEG stretch and GLP-2 stretch groups. Moreover, there was statistically greater diameter, crypt depth and EC proliferation in the GLP-2 stretch vs. PEG stretch groups. GLP-2 stretch vessel volume was greater than all other groups and was significantly increased compared to controls. The relative expression of PDGF increased significantly in the PEG stretch group vs. the control group. Conclusions GLP-2 had an additive effect on EC proliferation, tissue growth, histomorphology and vascularization. The combination of enterogenesis and GLP-2 may yield an improved approach to treat SBS. PMID:23639355

    Background Self-efficacy can be affected by mastery experiences and somatic sensations. A novel exercise experience and associated sensations may impact self-efficacy and subsequent behaviors. We investigated the effect of a single exercise session on self-efficacy for sedentary endometrial cancer survivors compared with sedentary women of a similar age, but with no cancer history. Methods Twenty survivors and 19 controls completed an exercise session performed as a submaximal cycle ergometry test. Sensations and efficacy were measured before and after exercise. Repeated measures analysis of variance (ANOVA) was performed. Regression models were used to determine predictors of self-efficacy and subsequent exercise. Results Self-efficacy increased for both survivors and controls, but survivors had a higher rate of increase, and the change predicted subsequent exercise. The association between exercise-related somatic sensations and self-efficacy differed between the 2 groups. Conclusions A novel exercise experience had a larger effect on self-efficacy and subsequent exercise activity for endometrial cancer survivors than controls. Somatic sensations experienced during exercise may differ for survivors, which may be related to the experience of having cancer. Understanding factors affecting confidence in novel exercise experiences for populations with specific cancer histories is of the utmost importance in the adoption of exercise behaviors.

    2015-01-01

    Self-efficacy has been proposed as an important element of a successful cognitive behavioral treatment (CBT). Positive changes in perceived self-efficacy have been linked to an improved adaptive emotional and behavioral responding in the context of anxiety-provoking situations. Furthermore, a positive influence of increased self-efficacy on cognitive functions has been confirmed. The present study examined the effect of verbal persuasion on perceived self-efficacy and fear extinction. Healthy participants were subjected to a standardized differential fear conditioning paradigm. After fear acquisition, half of the participants received a verbal persuasion aimed at increasing perceived self-efficacy. The extinction of fear was assessed immediately thereafter on both the implicit and explicit level. Our results suggest that an increased perceived self-efficacy was associated with enhanced extinction, evidenced on the psychophysiological level and accompanied by more pronounced decrements in conditioned negative valence. Changes in extinction were not due to a decrease in overall emotional reactivity to conditioned stimuli (CS). In addition, debriefing participants about the false positive feedback did not affect the processing of already extinguished conditioned responses during a subsequent continued extinction phase. Our results suggest that positive changes in perceived self-efficacy can be beneficial for emotional learning. Findings are discussed with respect to strategies aimed at increasing extinction learning in the course of exposure-based treatments. PMID:26528152

    This study compared the efficacy of Adeli suit treatment (AST) with neurodevelopmental treatment (NDT) in children with cerebral palsy (CP). Twenty-four children with CP, Levels II to IV according to the Gross Motor Function Classification System (GMFCS), were matched by age and functional status and randomly assigned to the AST or NDT treatment groups. In the AST group (n=12; eight males, four females; mean age 8.3 y [SD 2.0]), six children had spastic/ataxic diplegia, one triplegia and five spastic/mixed quadriplegia. In the NDT group (n=12; nine males, three females; mean age 8.1 y [SD 2.2]), five children had spastic diplegia and seven had spastic/mixed quadriplegia. Both groups were treated for 4 weeks (2 hours daily, 5 days per week, 20 sessions). To compare treatments, the Gross Motor Function Measure (GMFM-66) and the mechanical efficiency index (EIHB) during stair-climbing were measured at baseline, immediately after 1 month of treatment, and 10 months after baseline. The small but significant time effects for GMFM-66 and EIHB that were noted after 1 month of both intensive physiotherapy courses were greater than expected from natural maturation of children with CP at this age. Improvements in motor skills and their retention 9 months after treatment were not significantly different between the two treatment modes. Post hoc analysis indicated a greater increase in EIHB after 1 month (p=0.16) and 10 months (p=0.004) in AST than that in NDT, predominantly in the children with higher motor function (GMFCS Levels II and III). The results suggest that AST might improve mechanical efficiency without a corresponding gain in gross motor skills, especially in children with higher levels of motor function.

    Characteristics of relationship itself play an important role in determining well-being of individuals who participate in the relationship. We used efficacy expectations mutually shared between close friends or romantic partners as a characteristic of relationship and investigated its impact on their life satisfaction. In Study 1, we conducted a cross-sectional study among 137 pairs of close same-sex friends to test whether the efficacy expectations shared between friends are associated with levels of life satisfaction. In Study 2, we conducted a longitudinal study among 114 heterosexual romantic couples to test predictive validity of the efficacy expectations shared between couples predict levels of life satisfaction 2 month later. In both studies we found a consistent result that as degrees of the efficacy expectations shared between individuals in a relationship increased, the degree of their life satisfaction also increased. Underlying mechanisms that explain how characteristics of relationship itself increase life satisfaction are discussed. PMID:27437946

    2012-06-06

    This study sought to determine how eight days of home exposure to information about healthful foods and eating behaviors in the form of children's books and a variety of fruit and vegetables interacted to affect 4- to 8-year-old children's (N=59) consumption of fruit and vegetables. Before and after the home exposure, children participated in a task in which their consumption of a variety of fruit and vegetables that ranged in familiarity was measured. Results indicated that exposure to food and books were both effective at increasing consumption of fruit, but not vegetables. Additionally, children who were exposed to books consumed more of an infrequently consumed fruit presented during the post-test, but only if they had not been exposed to food during the home exposure. Overall, children's fruit consumption increased more if their mothers did not pressure them to eat, and those who were less neophobic were more likely to try a novel fruit or vegetable during the post-test. These findings suggest that information and food variety both can be effective for increasing acceptance of fruit, and highlight the need for more research that investigates the efficacy of intervention strategies that promote vegetable consumption in young children.

    The present study examined the impact of divided attention on children's and adults' neutral and negative true and false memories in a standard Deese/Roediger-McDermott paradigm. Children (7- and 11-year-olds; n = 126) and adults (n = 52) received 5 neutral and 5 negative Deese/Roediger-McDermott word lists; half of each group also received a divided attention task. The results showed that divided attention affected children's and adults' false memory levels differently but did not alter true memory differently. Our results revealed a developmental shift in that divided attention lowered children's false memory rates but increased adults' false memory rates, regardless of the nature of the material (i.e., neutral or negative). Our study indicates that manipulations that target conscious processing (e.g., divided attention) result in marked qualitative and quantitative differences between children's and adults' false memories but not true memories.

  1. Priming third-party ostracism increases affiliative imitation in children.

    Over, Harriet; Carpenter, Malinda

    2009-04-01

    Human beings are intensely social creatures and, as such, devote significant time and energy to creating and maintaining affiliative bonds with group members. Nevertheless, social relations sometimes collapse and individuals experience exclusion from the group. Fortunately for adults, they are able to use behavioral strategies such as mimicry to reduce their social exclusion. Here we test whether children, too, increase their imitation following an experience of ostracism. Given humans' profound need to belong, we predicted that the mere hint of social exclusion--even third-party social exclusion--would be sufficient to increase affiliative imitation in 5-year-olds. As predicted, children primed with videos in which one shape was ostracized by a group of other shapes subsequently imitated the actions of a model more closely than children in a control condition. These findings highlight just how sensitive humans are to social exclusion and demonstrate that children, like adults, modify their social behavior in response to ostracism.

    African American students are overrepresented in special education. Ecological systems theory, social cognitive theory, and a literature review demonstrate that children's environments, particularly school, and self-efficacy impact the educational outcomes of African American children. Interventions have aimed to improve children's environmental resources and efficacy. The aim of this study was to assess the impact of environment, efficacy beliefs, and the Nurse-Family Partnership intervention on the educational achievements of African American children in special education. A secondary data analysis of 126 African American children in special education found that self-efficacy and the number of hours spent in special education were associated with their academic achievement.

This was a random, double-blind, placebo-controlled, cross-over clinical trial performed on children with hyperlipidemia secondary to kidney disorders. After being placed on a diet for 3 months, patients were randomly placed in one of two balanced group blocks and treated with diet plus placebo or simvastatin at doses of 5 mg for children weighing 30 kg or less and 10 mg for children weighing over 30 kg, for 1 month, and then doubled for two more months. After this treatment, patients were placed on a diet for a 3-month washout period. During the last trial phase, patients previously treated with simvastatin were administered a placebo, and vice versa. A total of 25 patients with ages ranging from 4 years to 17 years were included in the study. A significant decrease in the levels of serum cholesterol (26.4%), low-density lipoprotein (LDL) (35.4%) and triglycerides (23.1%) was noted during the study, primarily during the simvastatin treatments, in which case cholesterol, LDL and triglycerides decreased by 23.3%, 33.7% and 21%, respectively. High-density lipoprotein (HDL) levels increased moderately (10.7%) during the study but without differences during simvastatin treatment. No differences were found across groups with respect to adverse events. In the short-term the combination of diet and simvastatin was effective in lowering hyperlipidemia in children with renal disorders.

    Recently, an association between childhood growth stunting and aflatoxin (AF) exposure has been identified. In Ghana, homemade nutritional supplements often consist of AF-prone commodities. In this study, children were enrolled in a clinical intervention trial to determine the safety and efficacy of Uniform Particle Size NovaSil (UPSN), a refined calcium montmorillonite known to be safe in adults. Participants ingested 0.75 or 1.5 g UPSN or 1.5 g calcium carbonate placebo per day for 14 days. Hematological and serum biochemistry parameters in the UPSN groups were not significantly different from the placebo-controlled group. Importantly, there were no adverse events attributable to UPSN treatment. A significant reduction in urinary metabolite (AFM1) was observed in the high-dose group compared with placebo. Results indicate that UPSN is safe for children at doses up to 1.5 g/day for a period of 2 weeks and can reduce exposure to AFs, resulting in increased quality and efficacy of contaminated foods.

    Fecal microbiota transplantation (FMT) is recognized as an alternative therapeutic modality for recurrent Clostridium difficile infection (RCDI); however, data on its efficacy in children are lacking, including its effect on their growth and fecal microbiota. We report on 2 young children (<3 years old) who failed available therapeutics for RCDI, but responded remarkably well to FMT. Besides resolution of clinical features of C difficile infection (CDI), FMT administration led to marked improvement in their growth, along with increased microbiota diversity, especially proportion of Bacteroides. Our 2 cases illustrate the efficacy of FMT in children with RCDI and its positive effect on their growth and gut microbiota.

  15. Searching for control: priming randomness increases the evaluation of ritual efficacy.

    PubMed

    Legare, Cristine H; Souza, André L

    2014-01-01

    Reestablishing feelings of control after experiencing uncertainty has long been considered a fundamental motive for human behavior. We propose that rituals (i.e., socially stipulated, causally opaque practices) provide a means for coping with the aversive feelings associated with randomness due to the perception of a connection between ritual action and a desired outcome. Two experiments were conducted (one in Brazil [n = 40] and another in the United States [n = 94]) to evaluate how the perceived efficacy of rituals is affected by feelings of randomness. In a between-subjects design, the Scramble Sentence Task was used as a priming procedure in three conditions (i.e., randomness, negativity, and neutral) and participants were then asked to rate the efficacy of rituals used for problem-solving purposes. The results demonstrate that priming randomness increased participants' perception of ritual efficacy relative to negativity and neutral conditions. Implications for increasing our understanding of the relationship between perceived control and ritualistic behavior are discussed.

    To evaluate the efficacy and safety of CLAVAMOX dry syrup (potassium clavulanate/amoxicillin) in children with otitis media, we conducted a postmarketing surveillance from February to September 2006. The analysis was made on the basis of 470 survey sheets collected from 127 medical institutions, of which we investigated 455 cases for safety, and 433 cases for efficacy. The efficacy was 95.2% in the 433 subjects eligible for the efficacy analysis. The clinical improvement rates for major symptoms (otalgia, otorrhea, flare reaction of drum membrane and fever) were 95% or more. The efficacies for the three major offending bacteria of otitis media (Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis) were between 94.6% and 100%. The efficacies for penicillin-resistant Streptococcus pneumoniae (PRSP) and penicillin intermediate resistant Streptococcus pneumoniae (PISP) were 95% or more. Adverse drug reactions (ADRs) were reported in 106 (23.3%) of the 455 subjects eligible for safety analysis. The major ADRs were diarrhea, of which incident was 22.6% (103 of 455). These ADRs were observed at a higher rate in younger age patients. Most of the diarrhea cases were non-serious, reversible on discontinuation or continuation of the drug. No clinically important serious diarrhea cases such as pseudomembranous colitis or dehydration were observed. Our surveillance results demonstrated that CLAVAMOX dry syrup had excellent efficacy and clinically manageable safety in children with otitis media. These findings indicated that this medicine was clinically-useful in children with otitis media.

    2008-08-01

    Epstein-Barr virus (EBV) infection after liver transplantation (LT) is associated with increased risk of posttransplant lymphoproliferative disorder (PTLD). Lowering immunosuppression is the current method to prevent PTLD in LT children with a high viral load. The aim of this study was to assess the efficacy and safety of valganciclovir (VGCV) in children with EBV infection after LT. Forty-seven children showing detectable EBV-DNA (72% asymptomatic) were treated with VGCV (520 mg/sqm twice daily) with no immunosuppression decrease (except in 4 cases). VGCV treatment started 17 months (median) after the onset of EBV infection. A 30-day treatment applied to 26 patients led to undetectable EBV-DNA in 11/32 courses (34.3%), with 82% relapsing. A long VGCV treatment (median: 8 months) achieved undetectable EBV-DNA in 20/42 (47.6%), 60% of whom maintained response off therapy. There were no new PTLD cases. Symptoms worsened in 1 (2.1%) in whom PTLD was suspected but not confirmed in liver and jejunum biopsies. Factors associated with achievement of undetectable EBV-DNA were a longer time from LT and a lower rate of intervening infections in comparison with nonresponders. The safety profile for VGCV was excellent. Graft rejection occurred in 6%. In conclusion, in 47 LT children with a sustained increased EBV load treated with VGCV and unchanged immunosuppression, PTLD was suspected in 1 child (2.1%). A viral load decrease could be achieved as EBV-DNA was undetectable in 47% of patients under prolonged treatment.

    Despite the well-documented health benefits of fruits and vegetables and the public health campaigns promoting their consumption, children's intake is below the recommended levels. A randomized controlled trial for evaluating the effectiveness of a school-based intervention for increasing children's fruit intake, with the teacher being the exposure model, was designed. Two hundred eighteen elementary school students (aged 9 years) in Cyprus were randomly assigned into two 1-year intervention groups, the Educational Material group (EDUC) (n=59) and the Exposure group (EXPO) (n=67), or a control group (n=58). Children's dietary intake was assessed through 2-day dietary records before the intervention began (October 2008), at the end of the intervention (June 2009), and at 1-year follow-up (June 2010). Students in the EDUC group received a weekly educational program for increasing awareness and improving skills regarding fruit preparation/consumption and students in the EXPO group were exposed to the consumption of a fruit on a daily basis by their teacher. The control group members received no intervention. Repeated measures analysis of variance was used to evaluate the group effect and the time×group interaction. Higher fruit intake was reported by the children in the EXPO and the EDUC groups compared with the control group at the end of the intervention: a statistically significant group effect was found (P<0.001). At 1-year follow-up, results remained significant only for the children in the EXPO group (P<0.001). Exposure to fruit consumption by schoolteachers may be a more effective way for improving fruit intake of children compared with traditional educational approaches.

    This randomized, placebo-controlled trial investigated the tolerance, efficacy, and nutritional benefit of combining chemotherapeutic treatment of intestinal helminths and lymphatic filariasis. Children were infected with Ascaris (30.7%), Trichuris (53.4%), and hookworm (9.7%) with 69.9% having more than one of these parasites. A total of 15.8% of the children had Wuchereria bancrofti microfilariae. Children were randomly assigned treatment with placebo, albendazole (ALB), diethylcarbamazine (DEC), or combined therapy. The combination of DEC/ALB reduced microfilarial density compared with placebo, ALB, or DEC (P < or = 0.03). Albendazole and DEC/ALB reduced the prevalence of Ascaris, Trichuris, and hookworm more than placebo or DEC (P < or = 0.03). Among Trichuris-infected children, those receiving ALB and DEC/ALB demonstrated greater gains in weight compared with placebo (P < or = 0.05). Albendazole and DEC/ALB were equally efficacious in treating intestinal helminths and for children with W. bancrofti microfilaremia, DEC/ALB was more effective than DEC, with no increase in severity of adverse reactions.

    Women are sparsely represented in leadership in academic science, technology, engineering, mathematics, and medicine (STEMM). Cultural stereotypes about men, women, and leaders influence the attitudes, judgments, and decisions that others make about women and the choices women make for themselves. Multilevel interventions are needed to counteract the impact of these pervasive and easily activated stereotypes, which conspire in multiple ways to constrain women's entry, persistence, and advancement in academic STEMM. We describe an individual-level educational intervention. Using the transtheoretical model of behavioral change as a framework, we assessed the success of a semester course on increasing women's leadership self-efficacy for the first three cohorts of course participants (n = 30). Pre/post questionnaires showed gains in leadership self-efficacy, personal mastery, and self-esteem, and decreases in perceived constraints. Qualitative text analysis of weekly journals indicated increasing leadership self-efficacy as course participants applied course information and integrated strategies to mitigate the impact of societal stereotypes into their own leadership practices. Follow-up queries of the first two cohorts supported the enduring value of course participation. We conclude that providing strategies to recognize and mitigate the impact of gender stereotypes is effective in increasing leadership self-efficacy in women at early stages of academic STEMM careers.

    Objective: Nutrition in childhood has an important role in current and adulthood health. Recent studies have shown that the mother’s lifestyle has an important role in the methods used by mother to feed child. This paper aimed to investigate the association between mother’s weight efficacy lifestyle with feeding practices in children aged 3- 6 years. Materials and Methods: In this cross-sectional study which was carried out in 30 primary schools of Rasht (Iran) in 2012, 165 mothers with children aged 3-6 years were participated. Mothers reported their own and their child’s demographics. Aspects of mother’s weight efficacy lifestyle and mother’s control practices were assessed using Weight Efficacy Lifestyle (WEL) questionnaire and Comprehensive Feeding Practices questionnaire (CFPQ) respectively. Height and weight of mothers participated in the study were measured. The role of mother’s weight efficacy in predicting child’s feeding practices was assessed using linear regression. Results: Results showed that mother’s weight efficacy was related to child feeding practices. The mothers with similar weight efficacy lifestyle applied similar methods in child nutrition. Mothers with better weight efficacy used more encourage balance and variety, environmental control, child involvement and less emotion regulation using foods. Conclusion: ‎ ‏ ‏‎ The result of the ‎study showed that maternal ‎lifestyle was associated with ‎child feeding practices.‎ PMID:27006673

    As a result of recent federal legislation and positive research findings of educators, children with disabilities, including hearing impairment, are being included in general education classrooms. This development has many implications at the state, district, and classroom levels. While helping the child with disabilities assimilate into the general education classroom may appear to be the teacher's primary challenge, increasing awareness and understanding among those students without disabilities is a growing concern of educators. The use of children's literature featuring children with disabilities is one way to promote this understanding. This article includes an annotated bibliography of children's literature featuring children with hearing impairment, along with related classroom activities to enhance experiences with the books.

  13. Mesenchymal stem cells and cutaneous wound healing: novel methods to increase cell delivery and therapeutic efficacy.

    PubMed

    Lee, Dylan E; Ayoub, Nagi; Agrawal, Devendra K

    2016-03-09

    Mesenchymal stem cells (MSCs) (also known as multipotent mesenchymal stromal cells) possess the capacity for self-renewal and multi-lineage differentiation, and their ability to enhance cutaneous wound healing has been well characterized. Acting via paracrine interactions, MSCs accelerate wound closure, increase angiogenesis, promote resolution of wound inflammation, favorably regulate extracellular matrix remodeling, and encourage regeneration of skin with normal architecture and function. A number of studies have employed novel methods to amplify the delivery and efficacy of MSCs. Non-traditional sources of MSCs, including Wharton's jelly and medical waste material, have shown efficacy comparable to that of traditional sources, such as bone marrow and adipose tissue. The potential of alternative methods to both introduce MSCs into wounds and increase migration of MSCs into wound areas has also been demonstrated. Taking advantage of the associations between MSCs with M2 macrophages and microRNA, methods to enhance the immunomodulatory capacity of MSCs have shown success. New measures to enhance angiogenic capabilities have also exhibited effectiveness, often demonstrated by increased levels of proangiogenic vascular endothelial growth factor. Finally, hypoxia has been shown to have strong wound-healing potential in terms of increasing MSC efficacy. We have critically reviewed the results of the novel studies that show promise for the continued development of MSC-based wound-healing therapies and provide direction for continued research in this field.

    Physical activity is crucial for children's health. Fitbit accelerometers were used to measure steps of 6 elementary students during recess. The intervention included reinforcement, self-monitoring, goal setting, and feedback. Steps taken during the intervention phase (M = 1,956 steps) were 47% higher than in baseline (M = 1,326 steps), and the percentage of recess spent in moderate-to-vigorous physical activity was higher during intervention (M = 25%) than in baseline (M = 4%). These methods successfully increased steps during recess and could be used to increase steps in other settings.

    Docetaxel (DTX) is an effective commercial anticancer agent for chemotherapy in non-small cell lung cancer (NSCLC), breast cancer, gastric cancer, and prostate cancer, but its adverse effects including edema, neurotoxicity, and hair loss limit its application. To improve the chemotherapeutic efficacy of DTX and reduce adverse effects, combination therapy is one of the alternative methods. So chrysin, which has various biological activities including anticancer effects, was considered. In vitro, the combination of chrysin and DTX was investigated in A549 cells. Increased cytotoxicity, suppressed cellular proliferation, and induced apoptosis were observed with posttreatment of chrysin following DTX treatment. In vivo, chrysin enhanced the tumor growth delay of DTX and increased DTX-induced apoptosis in the A549-derived xenograft model. Furthermore, chrysin prevented DTX-induced edema in ICR mouse. These results indicated that chrysin strengthened the therapeutic efficacy of DTX and diminished the adverse effect of DTX, suggesting chrysin could be exploited as an adjuvant therapy for NSCLC.

    Objective: The findings demonstrated that parents of children with cerebral palsy experience elevated levels of distress, depression, anxiety, posttraumatic stress symptom and subjective symptom of stress and low quality of life. Effective interventions targeting relapse have the potential to dramatically reduce the point prevalence of this condition. Many studies have shown that Mindfulness Based Cognitive Therapy (MBCT) is an intervention that has shown efficacy in improving quality of life. In this study, the effect of Mindfulness –Based Cognitive Therapy (MBCT) on increasing quality of life in mothers of children with cerebral palsy has been examined. Method: Three mothers of CP children with low scores on quality of life in WHOQOL-BREF inventory participated in this single- case study. Results: Findings revealed that the MBCT program elevated quality of life of the participants. The improvement quotient for quality of life of each participant was good . Conclusion: The results have implication for efficacy of mindfulness for improvement of psychosocial life of families of children with cerebral palsy. PMID:26884784

    Although radiotherapy (RT) is widely used to control tumor growth across many cancer types, there is a relatively high incidence of RT failure exhibited by tumor recurrence, therefore a clear need exists to achieve improved effectiveness of RT. The RT-elicited immune response largely impacts the efficacy of RT and includes immune cells that kill tumor cells, but also immunosuppressive cells, which dampen anti-tumor immunity. Using murine models in which syngeneic tumor cell lines (Colon38, Glioma261, Line1) are grown intramuscularly and treated with 15 Gy local RT, we assessed the effects of RT on both the systemic and intratumoral immune response. Here we demonstrate that RT stimulates increased production of two chemokines, CCL2 and CCL5, at the tumor site. Further, that this leads to increased CCR2+ CCR5+ monocytes in circulation and subsequently alters the intratumoral immune infiltrate favoring the largely immunosuppressive CCR2+ CCR5+ monocytes. Importantly, a CCR2/CCR5 antagonist administered daily (15 mg/kg subcutaneously) starting two days prior to RT reduces both circulating and intratumoral monocytes resulting in increased efficacy of RT in radioresponsive tumors. Overall, these data have important implications for the mechanism of RT and present a means to improve RT efficacy across many cancer types. PMID:27852031

    An ideal novel treatment for bone defects should provide regeneration without autologous or allogenous grafting, exogenous cells, growth factors, or biomaterials while ensuring spatial and temporal control as well as safety. Therefore, a novel osteoinductive nonviral in vivo gene therapy approach using sonoporation was investigated in ectopic and orthotopic models. Constitutive or regulated, doxycycline-inducible, bone morphogenetic protein 2 and 7 coexpression plasmids were repeatedly applied for 5 days. Ectopic and orthotopic gene transfer efficacy was monitored by coapplication of a luciferase plasmid and bioluminescence imaging. Orthotopic plasmid DNA distribution was investigated using a novel plasmid-labeling method. Luciferase imaging demonstrated an increased trend (61% vs. 100%) of gene transfer efficacy, and micro-computed tomography evaluation showed significantly enhanced frequency of ectopic bone formation for sonoporation compared with passive gene delivery (46% vs. 100%) dependent on applied ultrasound power. Bone formation by the inducible system (83%) was stringently controlled by doxycycline in vivo, and no ectopic bone formation was observed without induction or with passive gene transfer without sonoporation. Orthotopic evaluation in a rat femur segmental defect model demonstrated an increased trend of gene transfer efficacy using sonoporation. Investigation of DNA distribution demonstrated extensive binding of plasmid DNA to bone tissue. Sonoporated animals displayed a potentially increased union rate (33%) without extensive callus formation or heterotopic ossification. We conclude that sonoporation of BMP2/7 coexpression plasmids is a feasible, minimally invasive method for osteoinduction and that improvement of bone regeneration by sonoporative gene delivery is superior to passive gene delivery.

    Background: The modified Atkins diet (MAD) has been used predominantly in older children, adolescents, and adults. There is a paucity of data on the use of the MAD in refractory epilepsy in young children. Objectives: This study was planned to evaluate the efficacy and tolerability of the MAD in refractory epilepsy in young children. Methods: This study recruited children aged 9 months to 3 years with refractory seizures. Children received MAD for 6-month with the on-going anticonvulsant medications being continued unchanged. Reduction in seizure frequency was the primary outcome measure. Adverse effects were also studied. Results: Thirty-one children with daily seizures were studied with a median age of 18-month (range 9–30 months). West syndrome was the most common epilepsy syndrome (26, 86.6%). Twenty-one children remained on diet at 3 months and 13 at 6 months. The children who achieved >50% seizure reduction were 17 (54.8%) at 3 months and 9 (29%) at 6 months. Refusal to eat was a significant problem seen in eight children. Three children discontinued the diet due to adverse effects. Conclusion: The MAD was found to be feasible, effective, and well-tolerated. PMID:27994368

    A double-blind, randomized, clinical field trial was designed to test the efficacy and tolerance of a specific drug treatment in children in the indeterminate phase of infection by Trypanosoma cruzi. Children were treated with benznidazole at a dose of 5 mg/kg/day for 60 days or placebo and followed-up for 48 months. The treated children showed a significant decrease in geometric mean titers of antibodies against T. cruzi measured by indirect hemagglutination, indirect immunofluorescence, and ELISA. After a four year follow-up, 62% of the benznidazole-treated children and no placebo-treated child were seronegative for T. cruzi when tested by an ELISA using a T. cruzi flagellar calcium-binding protein (F29). Xenodiagnosis carried out after 48 months of follow-up was positive in 4.7% of the benznidazole-treated children and in 51.2% of the placebo-treated children. These results show the tolerance to and efficacy of benznidazole against T. cruzi in seropositive children six to 12 years of age. We used an early serologic marker of cure after treatment, consisting of a recombinant antigen implemented in a rapid, conventional serologic procedure.

    2010-01-01

    Background Anemia continues to be a major public health problem among children in many regions of the world, and it is still not clear which strategy to treat it is most effective. Objective To evaluate the efficacy and children's acceptance of several recognized strategies to treat anemia. Methods Non-breastfed children (n = 577), 6 to 43 mo of age, were screened for the trial; 267 were anemic (hemoglobin < 11.7 g/dL), and 266 of those were randomized into 1 of 5 treatments to received daily either: an iron supplement (IS), an iron+folic acid supplement (IFS), a multiple micronutrient supplement (MMS), a micronutrient-fortified complementary food as porridge powder (FCF), or zinc+iron+ascorbic acid fortified water (FW). The iron content of each daily dose was 20, 12.5, 10, 10 and 6.7 mg respectively. Hemoglobin (Hb), ferritin, total iron, weight and height were measured at baseline and after 4 months of treatment. Morbidity, treatment acceptability and adherence were recorded during the intervention. Results All treatments significantly increased Hb and total iron concentration; ferritin did not change significantly. Groups MMS, IS and IFS increased Hb (g/dL) [1.50 (95%CI: 1.17, 1.83), 1.48 [(1.18, 1.78) and 1.57 (1.26, 1.88), respectively] and total iron ((μg/dL) [0.15 (0.01, 0.29), 0.19 (0.06, 0.31) and 0.12(-0.01, 0.25), respectively] significantly more than FCF [0.92 (0.64, 1.20)] but not to FW group [0.14 (0.04, 0.24)]. The prevalence of anemia was reduced to a greater extent in the MMS and IFS groups (72% and 69%, respectively) than in the FCF group (45%) (p < 0.05). There were no significant differences in anthropometry or in the number of episodes of diarrhea and respiratory infections among treatment groups. The supplements MMS and IS were less acceptable to children, than IFS, FCF and FW. Conclusion The three supplements IS, ISF and MMS increased Hb more than the FCF; the supplements that contained micronutrients (IFS and MMS) were more effective for

    Biochar, a by-product of pyrolysis made from a wide array of plant biomass when producing biofuels, is a proposed soil amendment to improve soil health. This study measured herbicide sorption and efficacy when soils were treated with low (1% w/w) or high (10% w/w) amounts of biochar manufactured from different feedstocks [maize (Zea mays) stover, switchgrass (Panicum vigatum), and ponderosa pine (Pinus ponderosa)], and treated with different post-processing techniques. Twenty-four hour batch equilibration measured sorption of (14)C-labelled atrazine or 2,4-D to two soil types with and without biochar amendments. Herbicide efficacy was measured with and without biochar using speed of seed germination tests of sensitive species. Biochar amended soils sorbed more herbicide than untreated soils, with major differences due to biochar application rate but minor differences due to biochar type or post-process handling technique. Biochar presence increased the speed of seed germination compared with herbicide alone addition. These data indicate that biochar addition to soil can increase herbicide sorption and reduce efficacy. Evaluation for site-specific biochar applications may be warranted to obtain maximal benefits without compromising other agronomic practices.

    Variables that may be related to burnout in teachers of students with autism, including commitment to an underlying philosophy of a treatment and professional self-efficacy, were explored. Teachers using one of two different treatment approaches to autism participated: those using Applied Behavior Analysis (n = 34), and those using TEACCH (Treatment and Education of Autistic and Related Communication-Related Handicapped Children) (n = 30). Participants completed the Autism Treatment Philosophy Questionnaire, developed by the authors to differentiate between the philosophy of the approaches; Teacher Efficacy Scale, and Maslach Burnout Inventory. Results indicate a significant difference in philosophical commitment between the groups, but no differences in teaching efficacy or burnout. The relationship between a commitment to one's teaching approach and certain dimensions of teaching efficacy and burnout was found to be significant. Implications include the need for adequate training of teachers of students with autism.

    We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C. purpureum strains efficient in sprout control or highly active in laccase production, and tested the efficacy of their progeny in spout control experiments. This procedure resulted in a strain with an efficacy superior to that of the parental strains. The mortality of birch (Betula pendula Roth. and B. pubescens Ehrh.) 1 cm in stump diameter was 78%, 56% and 9% for the best progeny, the best parental strain and the control, respectively. Mortality was only slightly higher for B. pendula than for B. pubescens but no significant differences were found between the number or maximum height of stump sprouts. Our results showed that cross breeding of this decay fungus is a good alternative in attempts to produce efficient biocontrol agents against hardwood sprouting.

    Abstract Flexible bronchoscopy is more and more used for diagnosis and management of various pulmonary diseases in pediatrics. As poor coordination of children, the procedure is usually performed under general anesthesia with spontaneous or controlled ventilation to increase children and bronchoscopists’ safety and comfort. Previous studies have reported that dexmedetomidine (DEX) could be safely and effectively used for flexible bronchoscopy in both adulate and children. However, there is no trial to evaluate the dose-finding of safety and efficacy of dexmedetomidine-remifentanil (DEX-RF) in children undergoing flexible bronchoscopy. The objective of this study is to evaluate the dose-finding of safety and efficacy of DEX-RF in children undergoing flexible bronchoscopy. One hundred thirty-five children undergoing flexible bronchoscopy with DEX-RF were divided into 3 groups: Group DR1 (n = 47, DEX infusion at 0.5 μg·kg–1 for 10 minutes, then adjusted to 0.5–0.7 μg kg–1 h–1; RF infusion at 0.5 μg kg–1 for 2 minutes, then adjusted to 0.05–0.2 μg kg–1 min–1), Group DR2 (n = 43, DEX infusion at 1 μg kg–1 for 10 minutes, then adjusted to 0.5–0.7 μg kg–1 h–1; RF infusion at 1 μg kg–1 for 2 minutes, then adjusted to 0.05–0.2 μg kg–1 min–1), Group DR3 (n = 45, DEX infusion at 1.5 μg kg–1 for 10 minutes, then adjusted to 0.5–0.7 μg kg–1 h–1; RF infusion at 1 μg kg–1 for 2 minutes, then adjusted to 0.05–0.2 μg kg–1 min–1).

    The current multi-wave longitudinal study on childhood examined the role that social and academic self-efficacy beliefs and cognitive vulnerabilities play in predicting depressive symptoms in response to elevations in idiographic stressors. Children (N = 554; males: 51.4%) attending second and third grade completed measures of depressive symptoms, negative cognitive styles, negative life events, and academic and social self-efficacy beliefs at four time-points over 6 months. Results showed that high levels of academic and social self-efficacy beliefs predicted lower levels of depressive symptoms, whereas negative cognitive styles about consequences predicted higher depression. Furthermore, children reporting higher social self-efficacy beliefs showed a smaller elevation in levels of depressive symptoms when reporting an increases in stress than children with lower social self-efficacy beliefs. Findings point to the role of multiple factors in predicting children’s depression in the long term and commend the promotion of self-efficacy beliefs and the modification of cognitive dysfunctional styles as relevant protective factors.

  4. Increasing pesticide-resistant ectoparasitic infections may increase pesticide poisoning risks in children.

    PubMed

    Diaz, James H

    2008-01-01

    Head louse and scabies mite infestations are common among pre-school and school-age children, and topical pesticides are frequently prescribed to treat such conditions. Ectoparasite resistance to the safest and most commonly prescribed pyrethrin/pyrethroid pesticides for ectoparasitic infections has, however, been increasing since the 1980s. The increasing resistance of these arthropods to the safest pesticides may lead to greater use of more toxic, alternative pesticides to control infestations and to prevent institutional outbreaks. MEDLINE and Cochrane searches, 1966-2008, were conducted to assess the impact of increasing pesticide resistance on prescribing practices for ectoparasitic infections and to describe the evolving global epidemiology of pediatric poisonings by more toxic pediculicides and miticides, including carbamates, organochlorines, and organophosphates. Pharmacists, physicians, and poison control personnel should be fully informed about increasing pesticide resistance among the most commonly encountered ectoparasites of children and the institutionalized and be prepared to prevent and to treat accidental home and institutional pesticide poisonings with more toxic pesticides.

A double-blind, randomized, placebo-controlled, crossover clinical trial was conducted. Twenty healthy young volunteers were randomized into two treatment sequences using a series of random numbers. Sequence 1: Group A, 2% mepivacaine with 1:100,000 epinephrine plus submucous tramadol 50mg (1mL of saline) and one week later Group B, 2% mepivacaine with 1:100,000 epinephrine plus submucous placebo (1mL of saline). Sequence 2: Group B and one week later Group A. All treatments were administered 1min after that patient informed anesthesia of lower lip. We evaluated the duration of anesthesia of lower lip, anesthetic efficacy, and local and systemic adverse events. Anesthetic efficacy was better in group receiving submucous tramadol during the first 2h compared with group receiving submucous placebo (P<0.05). Submucous tramadol increased the anesthetic efficacy of mepivacaine with epinephrine of soft tissue in inferior alveolar nerve block.

    Objectives Internationally, general practitioners (GPs) are being encouraged to take an active role in the care of their patients with obesity, but as yet there are few tools for them to implement within their clinics. This study assessed the self-efficacy and confidence of GPs before and after implementing a weight management programme in their practice. Design Nested mixed methods study within a 6-month feasibility trial. Setting 4 urban general practices and 1 rural general practice in Australia. Participants All vocationally registered GPs in the local region were eligible and invited to participate; 12 GPs were recruited and 11 completed the study. Interventions The Change Programme is a structured GP-delivered weight management programme that uses the therapeutic relationship between the patient and their GP to provide holistic and person-centred care. It is an evidence-based programme founded on Australian guidelines for the management of obesity in primary care. Primary outcome measures Self-efficacy and confidence of the GPs when managing obesity was measured using a quantitative survey consisting of Likert scales in conjunction with pro forma interviews. Results In line with social cognitive theory, GPs who experienced performance mastery during the pilot intervention had an increase in their confidence and self-efficacy. In particular, confidence in assisting and arranging care for patients was improved as demonstrated in the survey and supported by the qualitative data. Most importantly from the qualitative data, GPs described changing their usual practice and felt more confident to discuss obesity with all of their patients. Conclusions A structured management tool for obesity care in general practice can improve GP confidence and self-efficacy in managing obesity. Enhancing GP ‘professional self-efficacy’ is the first step to improving obesity management within general practice. Trial registration number ACTRN12614001192673; Results. PMID:28132016

    The appearance of being scientific can increase persuasiveness. Even trivial cues can create such an appearance of a scientific basis. In our studies, including simple elements, such as graphs (Studies 1-2) or a chemical formula (Study 3), increased belief in a medication's efficacy. This appears to be due to the association of such elements with science, rather than increased comprehensibility, use of visuals, or recall. Belief in science moderates the persuasive effect of graphs, such that people who have a greater belief in science are more affected by the presence of graphs (Study 2). Overall, the studies contribute to past research by demonstrating that even trivial elements can increase public persuasion despite their not truly indicating scientific expertise or objective support.

    Background Repeated taste exposure, in combination with small rewards, has been shown to increase children's acceptance of disliked foods. However, previous studies have used direct contact with researchers or professionals for the implementation of the repeated exposure procedure. If mailed taste exposure instructions to parents produced comparable outcomes, this could be a cost-effective and easily disseminable strategy to promote healthier diets in children. Objective Our randomized controlled study aimed to test the efficacy and acceptability of mailed materials giving instructions on taste exposure as a means of increasing acceptance of vegetables in preschool-aged children. Design Participants were families of 3-year-old twins from the Gemini cohort who took part between March 2011 and April 2012. Families were randomized to a mailed intervention or a no treatment control condition. The intervention involved offering each child 14 daily tastes of a disliked (target) vegetable with a small reward (a sticker) if the child complied. Main outcome measures Outcomes were the child's intake of the target vegetable (number of pieces) and parent reports of the child's liking at two baseline (T1 and T2) and one postintervention (T3) behavior assessment. Results Record sheets with intake and liking data from T1, T2, and T3 were returned for 472 children, of which 442 were complete (94%). Over the intervention period (T2 to T3) intake and liking of the target vegetable increased significantly more in the intervention group than in the control group (intake: odds ratio 12.05, 95% CI 8.05 to 18.03, P<0.001; liking: odds ratio 12.34, CI 7.97 to 19.12, P<0.001). Acceptability of the procedure was very high among parents who completed the protocol. Conclusions Mailed instructions for taste exposure were effective in increasing children's acceptance of an initially disliked vegetable. These results support the value of parent-administered exposure to increase children

    Abstract Objectives: This extrapolation analysis qualitatively compared the efficacy and safety profile of atomoxetine from Lilly clinical trial data in 6–7-year-old patients with attention-deficit/hyperactivity disorder (ADHD) with that of published literature in 4–5-year-old patients with ADHD (two open-label [4–5-year-old patients] and one placebo-controlled study [5-year-old patients]). Methods: The main efficacy analyses included placebo-controlled Lilly data and the placebo-controlled external study (5-year-old patients) data. The primary efficacy variables used in these studies were the ADHD Rating Scale-IV Parent Version, Investigator Administered (ADHD-RS-IV-Parent:Inv) total score, or the Swanson, Nolan and Pelham (SNAP-IV) scale score. Safety analyses included treatment-emergent adverse events (TEAEs) and vital signs. Descriptive statistics (means, percentages) are presented. Results: Acute atomoxetine treatment improved core ADHD symptoms in both 6–7-year-old patients (n=565) and 5-year-old patients (n=37) (treatment effect: −10.16 and −7.42). In an analysis of placebo-controlled groups, the mean duration of exposure to atomoxetine was ∼7 weeks for 6–7-year-old patients and 9 weeks for 5-year-old patients. Decreased appetite was the most common TEAE in atomoxetine-treated patients. The TEAEs observed at a higher rate in 5-year-old versus 6–7-year-old patients were irritability (36.8% vs. 3.6%) and other mood-related events (6.9% each vs. <3.0%). Blood pressure and pulse increased in both 4–5-year-old patients and 6–7-year-old patients, whereas a weight increase was seen only in the 6–7-year-old patients. Conclusions: Although limited by the small sample size of the external studies, these analyses suggest that in 5-year-old patients with ADHD, atomoxetine may improve ADHD symptoms, but possibly to a lesser extent than in older children, with some adverse events occurring at a higher rate in 5-year-old patients.

    We demonstrate 2 novel mutations of the LHCGR, each homozygous, in a 46,XY patient with severe Leydig cell hypoplasia. One is a mutation in the signal peptide (p.Gln18_Leu19ins9; referred to here as SP) that results in an alteration of the coding sequence of the N terminus of the mature mutant receptor. The other mutation (p.G71R) is also within the ectodomain. Similar to many other inactivating mutations, the cell surface expression of recombinant human LHR(SP,G71R) is greatly reduced due to intracellular retention. However, we made the unusual discovery that the intrinsic efficacy for agonist-stimulated cAMP in the reduced numbers of receptors on the cell surface was greatly increased relative to the same low number of cell surface wild-type receptor. Remarkably, this appears to be a general attribute of misfolding mutations in the ectodomains, but not serpentine domains, of the gonadotropin receptors. These findings suggest that there must be a common, shared mechanism by which disparate mutations in the ectodomain that cause misfolding and therefore reduced cell surface expression concomitantly confer increased agonist efficacy to those receptor mutants on the cell surface. Our data further suggest that, due to their increased agonist efficacy, extremely small changes in cell surface expression of misfolded ectodomain mutants cause larger than expected alterations in the cellular response to agonist. Therefore, for inactivating LHCGR mutations causing ectodomain misfolding, the numbers of cell surface mutant receptors on fetal Leydig cells of 46,XY individuals exert a more exquisite effect on the relative severity of the clinical phenotypes than already appreciated.

    Introduction This study aims to adapt the Seizure Self-Efficacy Scale for Children (SSES-C) into Turkish and then assess its validity and reliability in children with epilepsy. Methods The study sample consisted of 166 children (aged 9–17 years) with epilepsy who attended of Akdeniz University Hospital, Antalya Training and Research Hospital, and Bursa Dortcelik Children’s Hospital Pediatric Neurology Clinics between July 2012 and March 2013. All research data were collected by a researcher in face-to-face interviews using Child Information Form, Seizure Self-Efficacy Scale for Children and Children’s Depression Scale. The Seizure Self-Efficacy Scale for Children is a 15-item, 5-point Likert scale designed by Caplin et al. (2002). Results The linguistic adaptation and validation of the scale was conducted by seven experts. To evaluate the content validity of the scale, we elicited judgments from a panel of 10 content experts. The expert judgments showed that the correlation between the items on the scale was fairly good (Kendall’s W=0.411, p<0.001, ki-kare: 57.495). Load factor of 40% and a large factor analysis included analysis of substances and two factors accounting for 49.67% of the total variance explained. We calculated Cronbach’s alpha coefficient for the internal consistency and the full-scale score showed good internal consistency (alpha 0.89). Within the context of reliability studies, it was found correlations varying between 0,98–0,74 for the two sub-factors of the scale. Test/retest correlation coefficients were significant (p<0,01) and high (r=0.99). In parallel forms reliability, the correlations between the Seizure Self-Efficacy Scale for Children and Children’s Depression Rating Scale were found to be negative, moderate and statistically significant (r=−0.58, p<0.001). Conclusion The measurements conducted on the Turkish version of the Seizure Self-Efficacy Scale for Children showed that it is consistent with the original scale

    Background Hydroxyurea is a cytotoxic and myelosuppressive drug that has been used during recent years in the treatment of children with severe sickle cell disease. Nevertheless, questions remain regarding its role in young patients with no severe course, like sickle/beta-thalassemia (S/b-thal) patients often present. The aim of the present study was to evaluate the safety and efficacy of hydroxyurea in young patients with S/b-thal, which is the commonest form of the disease in Greece. Patients-Methods Hydroxyurea was given in thirteen children with S/b-thal for 24 months and for that period clinical and laboratory evaluation of the children was performed. Results A reduction in pain crises and rate of hospitalization was noted. None of the patients presented with a severe clinical event, related to the disease during the study period. A significant increase in hemoglobin, hemoglobin F, mean corpuscular volume, and mean corpuscular hemoglobin and a decrease in reticulocyte count, white blood cell and platelet count, and total bilirubin level was noted. With regards to adverse events, these were transient, short-term and dose-dependable. Conclusions To the best of our knowledge, this is the first study to specifically assess the effect of hydroxyurea therapy in young patients with S/b-thal and the results indicate is safe and efficacious in this patient cohort.

    Acupuncture has been used therapeutically in China for thousands of years and is growing in prominence in Europe and the United States. In a recent review of complementary and alternative medicine use in the US population, an estimated 2.1 million people or 1.1% of the population sought acupuncture care during the past 12 months. Four percent of the US population used acupuncture at any time in their lives. We reviewed 31 different published journal articles, including 23 randomized controlled clinical trials and 8 meta-analysis/systematic reviews. We found evidence of some efficacy and low risk associated with acupuncture in pediatrics. From all the conditions we reviewed, the most extensive research has looked into acupuncture's role in managing postoperative and chemotherapy-induced nausea/vomiting. Postoperatively, there is far more evidence of acupuncture's efficacy for pediatrics than for children treated with chemotherapy. Acupuncture seems to be most effective in preventing postoperative induced nausea in children. For adults, research shows that acupuncture can inhibit chemotherapy-related acute vomiting, but conclusions about its effects in pediatrics cannot be made on the basis of the available published clinical trials data to date. Besides nausea and vomiting, research conducted in pain has yielded the most convincing results on acupuncture efficacy. Musculoskeletal and cancer-related pain commonly affects children and adults, but unfortunately, mostly adult studies have been conducted thus far. Because the manifestations of pain can be different in children than in adults, data cannot be extrapolated from adult research. Systematic reviews have shown that existing data often lack adequate control groups and sample sizes. Vas et al, Alimi et al, and Mehling et al demonstrated some relief for adults treated with acupuncture but we could not find any well-conducted randomized controlled studies that looked at pediatrics and acupuncture exclusively.

    Mitchell, Elizabeth Ann

    This qualitative, quasi-experimental study examined if lesson-study could be a successful approach in improving lesson plan quality and increasing self-efficacy levels toward teaching science at the preservice elementary teacher level in North Mississippi. Lesson-Study can be defined as a cycle of instructional improvement in which small groups work together to design and teach a lesson, revising again as needed over the course of a semester. This study described the experiences of two sections of preservice teachers enrolled in a science methods course as they engaged in lesson-study at a comprehensive university in Northeast Mississippi. One section of the class served as the control group while the other section, as the treatment group, received lesson-study over the course of the semester. Data was gathered in the form of interviews, observations, and a self-efficacy survey (STEBI-B). Lesson plans were also graded using a rubric to determine quality level. Findings indicated that, while not statistically significant, the treatment groups scores on the self-efficacy instrument increased more on average than the control groups' scores. There were also positive comments about the lesson study process from the teacher candidates in the treatment group as well as positive behaviors recorded by the researcher. Additionally, according to the external evaluators who graded the final drafts of the lessons, the treatment group had greater gains than the control class on average. These conclusions suggested the lesson study process implemented during the preservice teaching level can be beneficial.

    Children with autism have a high rate of irritability and aggressive symptoms. Irritability or self-injurious behavior can result in significant harm to those affected, as well as to marked distress for their families. This paper provides a literature review regarding the efficacy and tolerability of pharmacotherapy for the treatment of irritability in autistic children. Although antipsychotics have not yet been approved for the treatment of autistic children by many countries, they are often used to reduce symptoms of behavioral problems, including irritability, aggression, hyperactivity, and panic. However, among antipsychotics, the Food and Drug Administration has approved only risperidone and aripiprazole to treat irritability in autism. Among atypical antipsychotics, olanzapine and quetiapine are limited in their use for autism spectrum disorders in children because of high incidences of weight gain and sedation. In comparison, aripiprazole and ziprasidone cause less weight gain and sedation. However, potential QTc interval prolongation with ziprasidone has been reported. Contrary to ziprasidone, no changes were evident in the QT interval in any of the trials for aripiprazole. However, head-to-head comparison studies are needed to support that aripiprazole may be a promising drug that can be used to treat irritability in autistic children. On the other hand, risperidone has the greatest amount of evidence supporting it, including randomized controlled trials; thus, its efficacy and tolerability has been established in comparison with other agents. Further studies with risperidone as a control drug are needed. PMID:24932108

    Thirty-six febrile patients were administered cefpiramide (CPM) of 20 approximately 75 mg/kg/day for 3 approximately 11 days, and the clinical and side effects were evaluated. Among children with bacterial infections, including pneumonia, urinary tract infection, sepsis, pharyngitis and bronchitis, the results were excellent in 9, good in 13, and fair in 3 patients. Out of 36 patients, adverse reactions were observed in 9 cases, i.e. vascular pain at one shot intravenous injection in 4, diarrhea in 2, eosinophilia in 2, and diarrhea and eosinophilia in 1 case. One shot intravenous administration of CPM of 10 mg/kg to 4 patients yielded mean serum level of 100 micrograms/ml at 15 minutes and mean serum half-life of 2.5 hours, and administration of 20 mg/kg to 3 patients yielded mean serum level of 200 micrograms/ml at 15 minutes and mean serum half-life of 3.5 hours. The half-life in 1 patient with slight liver lesion was 5.36 hours. The rates of urinary recovery within 8 approximately 12 hours were 7.2 to 28.0% in 5 patients, 45.1% in a patient with nephrotic syndrome, and 50.9% in a patient with slight liver lesion.

    Background. A novel, micromobile foot compression device (MMC) has been developed to reduce the risk of venous thromboembolism associated with prolonged seated immobility. Objective. To compare the efficacy of the MMC with graduated compression stockings in augmenting lower limb venous blood flow. Patients/Methods. Twenty participants were randomised to wear the MMC or a graduated compression stocking (GCS) on either the left or right leg while seated. Doppler ultrasound measurements of popliteal vein blood flow and leg circumference measurements were made −30 and −10 minutes (baseline) and +30 and +60 minutes following application of the interventions. The primary outcome variable was peak systolic velocity. A mixed linear model was used, with covariates including baseline measurement, randomised side, time, and a time by interaction term. Results. The mean popliteal vein peak systolic velocity at 60 minutes with the MMC was 20.1 cm/s which was significantly higher than with the GCS (difference 14.1 cm/s 95% CI 12.1–16.2), representing a 3.8-fold increase from baseline. Conclusion. The MMC resulted in a marked increase in lower limb venous blood flow which suggests that it may have efficacy in reducing the risk of venous thromboembolism associated with prolonged seated immobility, such as long distance air travel.

    Purpose: Topotecan (TPT), a camptothecin analog, is currently used to treat human ovarian and small-cell lung cancer and is in clinical trials for other tumor sites. However, it is unknown whether chronomodulation of TPT treatment is beneficial. We examined the effects of administering TPT or X-radiation (XR) alone at different times of the day or night. Methods: We treated mice bearing human colorectal tumor xenografts at four different times representing the early rest period (9 AM or 3 HALO [hours after light onset]), late rest period (3 PM or 9 HALO), early active period (9 PM or 15 HALO), and late active period (3 AM or 21 HALO) of the mice. We gave either TPT (12 mg/kg, injected i.p.) or XR (4 Gy, directed to the tumor) twice weekly on Days 0, 4, 7, 10 within 2 weeks. Results: Treatment with either TPT or XR at 3 AM demonstrated the greatest efficacy (measured by a tumor regrowth assay) without significantly increasing acute toxicity (assessed by a decrease in leukocyte counts or body weight). Conversely, treatment at 3 PM, in particular, showed increased toxicity without any enhanced efficacy. Conclusions: Our study provided the first evidence that chronomodulation of TPT treatments, consistent with the findings of other camptothecin analogs, is potentially clinically beneficial. Additionally, our findings suggest that chronomodulation of fractionated XR treatments is also potentially clinically beneficial.

    The lack of effective and well-tolerated therapies against antibiotic-resistant bacteria is a global public health problem leading to prolonged treatment and increased mortality. To improve the efficacy of existing antibiotic compounds, we introduce a new method for strategically inducing antibiotic hypersensitivity in pathogenic bacteria. Following the systematic verification that the AcrAB-TolC efflux system is one of the major determinants of the intrinsic antibiotic resistance levels in Escherichia coli, we have developed a short antisense oligomer designed to inhibit the expression of acrA and increase antibiotic susceptibility in E. coli. By employing this strategy, we can inhibit E. coli growth using 2- to 40-fold lower antibiotic doses, depending on the antibiotic compound utilized. The sensitizing effect of the antisense oligomer is highly specific to the targeted gene’s sequence, which is conserved in several bacterial genera, and the oligomer does not have any detectable toxicity against human cells. Finally, we demonstrate that antisense oligomers improve the efficacy of antibiotic combinations, allowing the combined use of even antagonistic antibiotic pairs that are typically not favored due to their reduced activities.

    Project ImPACT is a parent-mediated social communication intervention for young children with ASD that was developed in community settings to encourage dissemination. A single-subject, multiple-baseline design was conducted across 8 preschoolers with ASD and their mothers to examine the efficacy of the model for improving parent intervention fidelity and child spontaneous language. Multilevel modeling was used to examine the relationship between parent fidelity and child language within session. All parents increased their use of the intervention techniques. Improvements in spontaneous use of language targets were observed for 6 of the 8 children. There was a significant association between parents' use of the intervention strategies and their child's spontaneous language use.

    Physically neglected youth are at increased risk of mental health problems, but there are few interventions that have demonstrated efficacy in reducing mental health symptoms for this vulnerable population. The Fostering Healthy Futures (FHF) program, which consists of mentoring and skills groups, was developed for preadolescent youth in foster care. In a published randomized controlled trial with 156 youth, FHF demonstrated positive impacts on mental health functioning. The current study sought to determine whether FHF might be particularly effective in ameliorating the impact of neglectful family environments. Because it was not possible to isolate a neglected-only subgroup, as most children with physical neglect histories had experienced other types of maltreatment, we tested the hypothesis that intervention effects would be stronger among children with more severe physical neglect. Findings did not support this hypothesis, however, as severity of physical neglect did not significantly moderate the impact of the intervention on psychosocial outcomes.

    This study's objective was to investigate the efficacy of sensory integration therapy (SIT) for children with high-functioning autism spectrum disorder (HFASD). The subjects were 20 HFASD children with IQs above 70 selected from previously collected data. Eight participated in individual SIT sessions, and 12 participated in group therapy (GT) including social skill training, communication training, kinetic activities, and child-parent play for 8-10 months. Changes in Total score and five Index scores on the Japanese version of the Miller Assessment for Preschoolers before and after therapy between children in the SIT and GT groups were compared. The results showed that Total score and all Index scores except for Verbal Index increased significantly in the SIT group, while only Total score increased in the GT group. Furthermore, the SIT group showed more improvement compared with the GT group in Total score and on Coordination, Non-verbal, and Complex Index scores. SIT might have a more positive effect on motor coordination abilities, non-verbal cognitive abilities, and combined abilities of sensory motor and cognition in children with HFASD when compared with GT. This study has limitations such as being an analysis of previously collected data. Further study should be conducted with a randomized control trial.

    Polypharmacy, defined as the concomitant use of two or more psychotropic drugs, has become increasingly common in the paediatric and adolescent population over the past two decades. Combining psychotropic drugs leads to possible increases in benefits, but also in risks, particularly given the potential for psychotropic drug interactions. Despite the increasing use of concomitant therapy in children and adolescents, there is very little evidence from controlled clinical trials to provide guidance for prescribers. Even while acknowledging the small evidence base, clinical practice guidelines from eminent medical organizations are either relatively silent on or tend to support the use of concomitant treatments more enthusiastically than the evidence would warrant, so that practice and guidance are running ahead of the science. Our narrative review shows that the published evidence for efficacy and safety of concomitant psychotropic drugs in children and adolescents is scanty. A comprehensive search located 37 studies published over the last decade, of which 18 were randomized controlled trials (RCTs). These focused mainly on stimulants, central sympatholytics (such as clonidine), antipsychotics and 'mood stabilizers'. While several small, often methodologically weak, RCTs demonstrated statistically significant advantages for dual pharmacotherapy over monotherapy, only adding central sympatholytics to stimulants for treating attention-deficit hyperactivity disorder (ADHD) symptoms was supported by substantial studies with an effect size large enough to suggest clinical importance. Non-randomized studies tended to have results that supported concomitant treatment, but all have design-related problems that decrease the reliability of the results. Two studies that specifically examined tolerability of combination pharmacotherapy compared with monotherapy showed significant increases in adverse effects, both subjective and objective, and other studies confirmed a

    Nanoscale drug delivery vehicles have been harnessed extensively as carriers for cancer chemotherapeutics. However, traditional pharmaceutical approaches for nanoformulation have been a challenge with molecules that exhibit incompatible physicochemical properties, such as platinum-based chemotherapeutics. Here we propose a paradigm based on rational design of active molecules that facilitate supramolecular assembly in the nanoscale dimension. Using cisplatin as a template, we describe the synthesis of a unique platinum (II) tethered to a cholesterol backbone via a unique monocarboxylato and O→Pt coordination environment that facilitates nanoparticle assembly with a fixed ratio of phosphatidylcholine and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino (polyethylene glycol)-2000]. The nanoparticles formed exhibit lower IC(50) values compared with carboplatin or cisplatin in vitro, and are active in cisplatin-resistant conditions. Additionally, the nanoparticles exhibit significantly enhanced in vivo antitumor efficacy in murine 4T1 breast cancer and in K-Ras(LSL/+)/Pten(fl/fl) ovarian cancer models with decreased systemic- and nephro-toxicity. Our results indicate that integrating rational drug design and supramolecular nanochemistry can emerge as a powerful strategy for drug development. Furthermore, given that platinum-based chemotherapeutics form the frontline therapy for a broad range of cancers, the increased efficacy and toxicity profile indicate the constructed nanostructure could translate into a next-generation platinum-based agent in the clinics.

Here we propose a paradigm based on rational design of active molecules that facilitate supramolecular assembly in the nanoscale dimension. Using cisplatin as a template, we describe the synthesis of a unique platinum (II) tethered to a cholesterol backbone via a unique monocarboxylato and O→Pt coordination environment that facilitates nanoparticle assembly with a fixed ratio of phosphatidylcholine and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino (polyethylene glycol)-2000]. The nanoparticles formed exhibit lower IC50 values compared with carboplatin or cisplatin in vitro, and are active in cisplatin-resistant conditions. Additionally, the nanoparticles exhibit significantly enhanced in vivo antitumor efficacy in murine 4T1 breast cancer and in K-RasLSL/+/Ptenfl/fl ovarian cancer models with decreased systemic- and nephro-toxicity. Our results indicate that integrating rational drug design and supramolecular nanochemistry can emerge as a powerful strategy for drug development. Furthermore, given that platinum-based chemotherapeutics form the frontline therapy for a broad range of cancers, the increased efficacy and toxicity profile indicate the constructed nanostructure could translate into a next-generation platinum-based agent in the clinics.

    The current studies utilized drift diffusion modeling (DDM) to examine how reinforcement and stimulant medication affect cognitive task performance in children with ADHD. In Study 1, children with (n = 25; 88 % male) and without ADHD (n = 33; 82 % male) completed a 2-choice discrimination task at baseline (100 trials) and again a week later under alternating reinforcement and no-reinforcement contingencies (400 trials total). In Study 2, participants with ADHD (n = 29; 72 % male) completed a double-blind, placebo-controlled trial of 0.3 and 0.6 mg/kg methylphenidate and completed the same task utilized in Study 1 at baseline (100 trials). Children with ADHD accumulated information at a much slower rate than controls, as evidenced by a lower drift rate. Groups were similar in nondecision time and boundary separation. Both reinforcement and stimulant medication markedly improved drift rate in children with ADHD (ds = 0.70 and 0.95 for reinforcement and methylphenidate, respectively); both treatments also reduced boundary separation (ds = 0.70 and 0.39). Reinforcement, which emphasized speeded accuracy, reduced nondecision time (d = 0.37), whereas stimulant medication increased nondecision time (d = 0.38). These studies provide initial evidence that frontline treatments for ADHD primarily impact cognitive performance in youth with ADHD by improving the speed/efficiency of information accumulation. Treatment effects on other DDM parameters may vary between treatments or interact with task parameters (number of trials, task difficulty). DDM, in conjunction with other approaches, may be helpful in clarifying the specific cognitive processes that are disrupted in ADHD, as well as the basic mechanisms that underlie the efficacy of ADHD treatments.

    Objective B cell depletion therapy (BCDT) ameliorates rheumatoid arthritis by mechanisms that are incompletely understood. Arthritic flare in tumor necrosis factor transgenic (TNF-Tg) mice is associated with efferent lymph node (LN) “collapse,” triggered by B cell translocation into lymphatic spaces and decreased lymphatic drainage. We examined whether BCDT efficacy is associated with restoration of lymphatic drainage due to removal of obstructing nodal B cells. Methods We developed contrast-enhancement (CE) MRI imaging, near-infrared indocyanine green (NIR-ICG) imaging, and intravital immunofluorescent imaging to longitudinally assess synovitis, lymphatic flow, and cell migration in lymphatic vessels in TNF-Tg mice. We tested to see if BCDT efficacy is associated with restoration of lymphatic draining and cell egress from arthritic joints. Results Unlike active lymphatics to normal and pre-arthritic knees, afferent lymphatic vessels to collapsed LNs in inflamed knees do not pulse. Intravital immunofluorescent imaging demonstrated that CD11b+ monocytes/macrophages in lymphatic vessels afferent to expanding LN travel at high velocity (186 ± 37 micrometer/sec), while these cells are stationary in lymphatic vessels afferent to collapsed PLN. BCDT of flaring TNF-Tg mice significantly decreased knee synovial volume by 50% from the baseline level, and significantly increased lymphatic clearance versus placebo (p<0.05). This increased lymphatic drainage restored macrophages egress from inflamed joints without recovery of the lymphatic pulse. Conclusion These results support a novel mechanism in which BCDT of flaring joints lessens inflammation by increasing lymphatic drainage and subsequent migration of cells and cytokines from the synovial space.

    2013-01-01

    Raltegravir was the first HIV integrase strand-transfer inhibitor to be approved by the US FDA, in October 2007, for the treatment of HIV-1 infection in combination with other antiretroviral agents. Raltegravir can be used in treatment-naïve and -experienced patients, as well as for the treatment of multidrug-resistant infection. Raltegravir exists in two formulations: a film-coated tablet administered orally at 400 mg twice daily, and a chewable tablet administered orally at 300 mg twice daily. In 2011, raltegravir was also approved for the treatment of children and adolescents, ages 2–18 years. For adolescents (ages 12–18 years), the recommended dose is 400 mg twice daily (film-coated tablet). If children (ages 6–12 years) weigh at least 25 kg, the film-coated tablet is recommended at 400 mg twice daily. Otherwise, patients receive the chewable tablet according to weight-based dosing at approximately 6 mg/kg/dose. Studies are ongoing for children ages 4 weeks to 2 years, and preliminary efficacy and safety data are promising. This article reviews current studies on the efficacy, safety, and pharmacokinetics of raltegravir in the pediatric population and the challenges of treating HIV in children and adolescents.

    Adoptive T cell immunotherapy is a promising approach to cancer treatment that currently has limited clinical applications. DNA methyltransferase inhibitors (DNAMTi) have known potential to affect the immune system through multiple mechanisms that could enhance the cytotoxic T cell responses, including: upregulation of tumor antigen expression, increased MHC class I expression, and blunting of myeloid derived suppressor cells (MDSCs) expansion. In this study, we have investigated the effect of combining the DNAMTi, decitabine, with adoptive T cell immunotherapy in the murine 4T1 mammary carcinoma model. We found that expression of neu, MHC class I molecules, and several murine cancer testis antigens (CTA) was increased by decitabine treatment of 4T1 cells in vitro. Decitabine also increased expression of multiple CTA in two human breast cancer cell lines. Decitabine-treated 4T1 cells stimulated greater IFN-gamma release from tumor-sensitized lymphocytes, implying increased immunogenicity. Expansion of CD11b + Gr1 + MDSC in 4T1 tumor-bearing mice was significantly diminished by decitabine treatment. Decitabine treatment improved the efficacy of adoptive T cell immunotherapy in mice with established 4T1 tumors, with greater inhibition of tumor growth and an increased cure rate. Decitabine may have a role in combination with existing and emerging immunotherapies for breast cancer.

    Background and Aims: The perioperative behavioural studies demonstrate that children are at greater risk of experiencing turbulent anaesthetic induction and adverse behavioural sequelae. We aimed to compare the efficacy of midazolam 0.5 mg/kg with triclofos sodium 100 mg/kg as oral premedication in children undergoing elective surgery. Methods: In this prospective, randomised and double-blind study, sixty children posted for elective lower abdominal surgery were enrolled. The patients were randomly divided into midazolam group (Group M) and triclofos sodium group (Group T) of thirty each. Group M received oral midazolam 0.5 mg/kg 30 min before induction, and Group T received oral triclofos sodium 100 mg/kg 60 min before induction. All children were evaluated for level of sedation after premedication, behaviour at the time of separation from parents and at the time of mask placement for induction of anaesthesia. Mann–Whitney U-test was used for comparing the grade of sedation, ease of separation and acceptance of face mask. Results: Oral midazolam produced adequate sedation in children after premedication in comparison to oral triclofos (P = 0.002). Both drugs produced successful separation from parents, and the children were very cooperative during induction. No adverse effects attributable to the premedicants were seen. Conclusions: Oral midazolam is superior to triclofos sodium as a sedative anxiolytic in paediatric population. PMID:27330204

    This randomized, observer-blind, parallel, controlled study determined the efficacy of an essential oils-containing (EO) antiseptic mouthrinse (in conjunction with toothbrushing) in reducing and/or controlling existing plaque or gingivitis over 6 months. Toothbrushing, combined with placebo rinsing, served as the control (C). Following ethics board approval (Biosci Research Canada, Ltd. Institutional Review Board), 139 healthy adults with mild to moderate plaque and gingivitis were randomized into EO or C groups. All subjects received oral/written instructions, monthly monitoring, and assigned unsupervised rinses. Efficacy variables were whole-mouth mean modified gingival index (MGI), Turesky modification of the Quigley Hein plaque index (PI), bleeding index (BI) at 6, 12, and 24 weeks, and data analysis through an analysis of covariance (ANCOVA) model. The EO group provided greater and increasing MGI, PI, and BI reductions than did C group over all examination periods. Compared to the C group, at 6, 12, and 24 weeks, MGI reductions for the EO group were 4.7%, 9.1%, and 20.4%, and PI reductions were 7.6%, 12.6%, and 26.3%, respectively. BI scores decreased over time and were significant compared to those for the C group (P < 0.001). Additionally, the percentages of sites improved versus baseline MGI over time for EO were 14.1%, 26.4%, and 43.3%, respectively. This study demonstrated that an EO-containing mouthrinse can provide an increasing benefit over a period of 6 months with twice daily use. This study also confirmed that an antiseptic EO rinse can provide a clinically significant benefit in reducing existing plaque and gingivitis.

    Rudy, Brittany M; Davis, Thompson E; Matthews, Russell A

    2012-09-01

    Evidence suggests that general self-efficacy, an individual's beliefs about his global abilities, and social self-efficacy, an individual's beliefs in his ability to navigate social situations, are strongly connected to levels of social anxiety. Negative self-statements, also known as negative self-referent cognitions, have also been linked with levels of social anxiety. Although self-efficacy and negative self-statements have been shown to be important variables in the phenomenology and maintenance of social anxiety in children, they have yet to be examined in conjunction with one another. The purpose of this study was to examine the relationship between negative self-referent cognitions and self-efficacy and to examine both general self-efficacy and social self-efficacy as mediator variables in the relationship between negative self-statements and social anxiety. Results were based on a sample of 126 children ages 11 to 14 years. A significant association between negative self-statements and both general self-efficacy and social self-efficacy was established. Results also indicated that general self-efficacy fully mediated the relationship between negative self-statements and social anxiety; however, contrary to hypotheses, social self-efficacy did not mediate the relationship between negative self-statements and social anxiety. Implications and future recommendations are discussed.

    2015-10-01

    The efficacy of de novo everolimus with reduced-exposure calcineurin inhibitor (CNI) was examined in kidney transplant subpopulations from the A2309 study that were identified to be at increased risk for efficacy events. A2309 was a 24-month, multicenter, open-label trial in which 833 de novo kidney transplant recipients were randomized to everolimus targeting 3-8 or 6-12 ng/ml with reduced-exposure cyclosporine (CsA), or mycophenolic acid (MPA) with standard-exposure CsA, all with basiliximab induction. The composite efficacy endpoint was treated biopsy-proven acute rejection (BPAR), graft loss, death, or loss to follow-up. Cox proportional hazard modeling showed male gender, younger recipient age, black race, delayed graft function, human leukocyte antigen (HLA) mismatch ≥3 and increasing donor age to be significantly predictive for the composite efficacy endpoint at months 12 or 24 post-transplant. CsA exposure was 53-75 % lower, and 46-75 % lower, in patients receiving everolimus 3-8 ng/ml or receiving everolimus 6-12 ng/ml, respectively, versus MPA-treated patients. The incidence of the composite endpoint was similar in all three treatment groups within each subpopulation analyzed. The incidence of treated BPAR was similar with everolimus 3-8 ng/ml or MPA in all subpopulations, but less frequent with everolimus 6-12 ng/ml versus MPA in patients with HLA mismatch ≥3 (p = 0.049). This post hoc analysis of a large, randomized trial suggests that a de novo regimen of everolimus with reduced-exposure CsA maintains immunosuppressive efficacy even in kidney transplant patients at increased risk for efficacy events despite substantial reductions in CsA exposure.

    2016-01-01

    It has been difficult to translate promising results from DNA vaccination in mice to larger animals and humans. Previously, DNA vaccines encoding proteins that target Ag to MHC class II (MHC-II) molecules on APCs have been shown to induce rapid, enhanced, and long-lasting Ag-specific Ab titers in mice. In this study, we describe two novel DNA vaccines that as proteins target HLA class II (HLA-II) molecules. These vaccine proteins cross-react with MHC-II molecules in several species of larger mammals. When tested in ferrets and pigs, a single DNA delivery with low doses of the HLA-II–targeted vaccines resulted in rapid and increased Ab responses. Importantly, painless intradermal jet delivery of DNA was as effective as delivery by needle injection followed by electroporation. As an indication that the vaccines could also be useful for human application, HLA-II–targeted vaccine proteins were found to increase human CD4+ T cell responses by a factor of ×103 in vitro. Thus, targeting of Ag to MHC-II molecules may represent an attractive strategy for increasing efficacy of DNA vaccines in larger animals and humans. PMID:27671110

    2016-12-01

    This paper describes the findings of a pilot study that used robotics and game design to develop middle school students' computational thinking strategies. One hundred and twenty-four students engaged in LEGO® EV3 robotics and created games using Scalable Game Design software. The results of the study revealed students' pre-post self-efficacy scores on the construct of computer use declined significantly, while the constructs of videogaming and computer gaming remained unchanged. When these constructs were analyzed by type of learning environment, self-efficacy on videogaming increased significantly in the combined robotics/gaming environment compared with the gaming-only context. Student attitudes toward STEM, however, did not change significantly as a result of the study. Finally, children's computational thinking (CT) strategies varied by method of instruction as students who participated in holistic game development (i.e., Project First) had higher CT ratings. This study contributes to the STEM education literature on the use of robotics and game design to influence self-efficacy in technology and CT, while informing the research team about the adaptations needed to ensure project fidelity during the remaining years of the study.

    Blanco, Felix C; Sandler, Anthony D; Nadler, Evan P

    2012-10-01

    Based on their clinical impression, the authors hypothesized that children with obesity may more commonly present with perforated appendicitis. Therefore, the authors reviewed their experience from 2008 to 2010 to determine whether obesity affected the clinical presentation of appendicitis. Variables studied were height, weight, use of diagnostic imaging, and clinical findings of appendicitis at presentation. Outcomes assessed were length of stay and complication rate. The study identified 319 patients with appendicitis. Children with obesity were more likely (P = .026) to present with perforation (28/62, 45%) than nonobese patients (78/257, 30%). Neither length of stay nor complication rate was affected by the presence of obesity. The data suggest that children with obesity are more likely to present with perforated appendicitis. This finding suggests that the diagnosis of appendicitis may be more difficult in obese patients or their presentation may be delayed. Practitioners should have heightened awareness in children with obesity and symptoms of abdominal pain.

    The objective of the study was to determine the safety and efficacy of squaric acid dibutyl ester (SADBE) therapy on the treatment of recalcitrant warts in children. This retrospective chart review examined 72 patients treated using SADBE from July 2002 to December 2012. Patients were followed for 6 months to 11 years. Patients were treated at a pediatric dermatology outpatient clinic at the University of North Carolina at Chapel Hill. Seventy-two children with verrucae who failed initial treatment for warts were selected for the study. Full long-term follow-up was obtained in 48 patients. Four patients discontinued the use of SADBE because of adverse effects. The primary study outcome was efficacy of SADBE treatment. Adverse effects, dosages administered, type of wart, other cutaneous disease present, and level of immunosuppression were measured. Forty of 48 (83%) patients in whom treatment outcomes could be obtained reported complete resolution of their warts. Seventy percent of patients used a maximum concentration of 0.4% SADBE and 60% of patients reported no adverse effects. The majority of patients treated with SADBE reported complete resolution of warts. Most patients reported no adverse effects even while receiving doses as high as 2% daily. This study shows that SADBE is a safe and effective treatment for recalcitrant warts in children.

    The current study examined intergenerational processes related to familism values among grandmothers, adolescent mothers, and their children. Mexican-origin families (N = 180) participated in in-home interviews during adolescent mothers' third trimester of pregnancy and 10-, 24-, 48-, and 60-months postpartum. Using longitudinal path analyses, we linked grandmothers' familism values and behaviors to adolescent mothers' parenting processes and, in turn, their child's well-being, taking into account developmentally relevant needs of adolescent mothers. Results revealed that grandmothers' familism values before the birth of the baby predicted child-rearing support and communication within the grandmother-adolescent mother dyad after the birth of the baby. Support, but not communication, was in turn predictive of adolescent mothers' parenting self-efficacy, but only at high levels of autonomy granting within the grandmother-adolescent mother dyad. Finally, adolescent mothers' parenting self-efficacy predicted children's greater social competence (48 months old), which in turn, predicted greater academic functioning (60 months old). Our findings shed light on the behavioral correlates of familism values within Mexican-origin families with adolescent mothers and highlight the need to consider factors that are developmentally salient (e.g., autonomy) when understanding how familism behaviors benefit adolescent mothers and their children.

    Lacosamide is FDA-approved in patients 17 years or older with partial-onset epilepsy. We evaluated the efficacy and tolerability of lacosamide in children with refractory generalized epilepsy. We retrospectively reviewed records of 21 children with refractory generalized epilepsy treated with lacosamide in our institution from 2009-2013 divided into 2 subgroups- I, Lennox-Gastaut Syndrome, and II, other generalized epilepsies. Efficacy was defined as seizure freedom or ≥50% seizure reduction. Descriptive data analysis including seizure freedom was compared using c(2) analysis. There were eleven females and ten males with a mean age, of 11.9 years. Five patients became seizure free, nine had ≥50% seizure reduction, and seven had no response. Group I: seven had ≥50% improvement, one did not respond. Group II: five became seizure free, two had ≥50% improvement, five had no response. Lacosamide is effective and well tolerated in children with refractory generalized epilepsy particularly patients with Lennox-Gastaut Syndrome.

The objective of our study was to evaluate its efficacy/safety in children with refractory epilepsy. Forty children (mean age 14.3 years) were treated with lacosamide at our institution (adjunctive therapy in 36, monotherapy in 4). Fifteen patients had symptomatic focal epilepsy, 2 had cryptogenic focal epilepsy, 20 had symptomatic generalized epilepsy, and 3 had cryptogenic generalized epilepsy. Two had juvenile myoclonic epilepsy and 5 had Lennox-Gastaut syndrome. Forty-two percent had at least >50% reduction in seizure frequency, and 6 became seizure free. Average dose was 7 mg/kg/d and average follow-up was 9.2 months. Responders had a 76.5% mean decrease in seizures. Fifteen children experienced an adverse reaction and 7 discontinued lacosamide (4: Ineffective, I: insurance denial, 1: tremor, 1: behavior). Lacosamide is effective and well-tolerated in children with refractory epilepsy.

    Objective To evaluate the effectiveness of intensive neurodevelopmental treatment (NDT) on gross motor function for the children having developmental delay (DD), with or without cerebral palsy (CP). Methods Forty-two children had intensive NDT three times weekly, 60 minutes a day, for 3 months, immediately followed by conventional NDT once or twice a week, 30 minutes a day, for another 3 months. We assessed Gross Motor Function Measure (GMFM) over three time points: before conventional NDT, before and after intensive NDT, and after 3 months of additional conventional NDT. Results The GMFM score in DD children significantly improved after intensive NDT, and the improvement maintained after 3 months of conventional NDT (p<0.05). The children were further divided into two groups: DD with CP and DD without CP. Both groups showed significant improvement and maintained the improvements, after intensive NDT (p<0.05). Also, there was no significant difference in treatment efficacy between the two groups. When we calculate the absence rate for comparing the compliance between intensive and conventional NDT, the absence rate was lower during the intensive NDT. Conclusion Intensive NDT showed significantly improved gross motor function and higher compliance than conventional NDT. Additionally, all improvements were maintained through subsequent short-term conventional NDT. Thus, we recommend the intensive NDT program by day-hospital centers for children with DD, irrespective of accompanying CP. PMID:28289640

    Objectives: Triclofos may be a better sedative in view of better palatability and less gastric irritation as compared to chloral hydrate. This study aimed to assess the efficacy of triclofos (a commonly used sedative in India) as a sedative for sleep electroencephalogram (EEG) study in children. Methods: This prospective observational study was carried out in a tertiary care pediatric center. Consecutive children aged 6 months to 5 years referred for sleep EEG evaluation were recruited. Their clinical details were noted in a proforma after an informed consent. After a trial for natural sleep, oral triclofos was administered. Sleep parameters and adverse effects were noted. Results: One-hundred and sixty children were then enrolled. EEG was successfully recorded in 149 (93.1%) children. Median latency of sleep onset was 30 min and median duration of sleep was 90 min. The adverse effects in the following 24 h were mild and included dizziness, irritability, and vomiting. Conclusions: Oral triclofos was found to be an effective sedative for EEG in children with minimal adverse effects. PMID:27606015

    Background Low levels of moderate-to-vigorous physical activity are associated with adverse health consequences. Objective The intent of the study was to determine the feasibility and efficacy of a 12-week physical activity promotion program targeting children, which was delivered to parents through mobile phones. Methods Potential participants were recruited through advertisements placed in the newspaper, local hospitals and schools, and an email listserv. Sedentary children aged 6-10 years were randomly assigned to a minimal (MIG) or intensive (IIG) intervention group. Parents in the MIG were given a goal to increase (within 1 month) and maintain their child’s activity at 6000 pedometer steps/day above their baseline levels and to monitor their child’s steps daily. Parents in the IIG were given the same steps/day and monitoring goals, in addition to text messages and articles containing additional behavioral strategies (based on the Social Cognitive Theory) designed to promote their child’s physical activity. The intervention components were delivered via mobile phone. Anthropometrics, body composition, and questionnaires were administered in a clinic. Children wore a New Lifestyles pedometer (NL-1000) each day throughout the intervention and parents were to monitor their child’s step counts daily. Results Out of 59 children who screened for the study, a total of 27 children (mean age 8.7, SD 1.4 years; 56%, 15/27 female; 59%, 16/27 African American) were enrolled and completed the study. Overall, 97.90% (2220/2268; 98.20%, 1072/1092 for MIG; 97.60%, 1148/1176 for IIG) of expected step data were successfully entered by the parent or study coordinator. Parents in the MIG and IIG were sent approximately 7 and 13 text messages per week, respectively, averaged over the course of the study. IIG parents accessed an average of 6.1 (SD 4.4) articles over the course of the intervention and accessed a fewer number of articles in the last month compared to the first

    The discovery of JAK2/MPL mutations in patients with myeloproliferative neoplasms (MPN) led to clinical development of Janus kinase (JAK) inhibitors for treatment of MPN. These inhibitors improve constitutional symptoms and splenomegaly but do not significantly reduce mutant allele burden in patients. We recently showed that chronic exposure to JAK inhibitors results in inhibitor persistence via JAK2 transactivation and persistent JAK–signal transducer and activator of transcription signaling. We performed genetic and pharmacologic studies to determine whether improved JAK2 inhibition would show increased efficacy in MPN models and primary samples. Jak2 deletion in vivo led to profound reduction in disease burden not seen with JAK inhibitors, and deletion of Jak2 following chronic ruxolitinib therapy markedly reduced mutant allele burden. This demonstrates that JAK2 remains an essential target in MPN cells that survive in the setting of chronic JAK inhibition. Combination therapy with the heat shock protein 90 (HSP90) inhibitor PU-H71 and ruxolitinib reduced total and phospho-JAK2 and achieved more potent inhibition of downstream signaling than ruxolitinib monotherapy. Combination treatment improved blood counts, spleen weights, and reduced bone marrow fibrosis compared with ruxolitinib alone. These data suggest alternate approaches that increase JAK2 targeting, including combination JAK/HSP90 inhibitor therapy, are warranted in the clinical setting. PMID:24470592

    Objective: This research was performed to investigate the efficacy of complex rehabilitation combined with pharmacopuncture treatment for the children with neuromotor system diseases. Methods: Fifty (50) patients aged from 5 to 15 yr old were compared. Twenty (20) patients received conventional treatments and complex rehabilitation as a control group, and fifty (50) patients received complex rehabilitation with pharmacopuncture. At their first visits, the patients had checkups and neurological scales, and after 10 days of pharmacopuncture treatments and 55 days of rehabilitation, they also took neurological scales. We studied the pre and post effects of the treatment group. Results: The number of patients with ankle joint disorder and contracture, knee joint contracture, steppage, horsey hoof, shoulder weakness and contracture, radio-carpal joint disorder and contracture, arm hypotrophia, arm atrophia, leg hypotrophia and total atrophia decreased after treatments. Conclusion: This study showed the efficacy of pharmacopuncture combined with complex rehabilitation for the treatment of neuromotor system diseases. PMID:25780664

    The antitussive efficacy and tolerability of dropropizine and of its enantiomer levodropropizine were evaluated in children with non-productive cough; 258 were evaluable for tolerability and 254 for efficacy. Patients randomly received either 1 mg/kg dropropizine or 2 mg/kg levodropropizine orally, three times daily for 3 days. There were statistically significant decreases in the frequency of coughing spells and nocturnal awakenings after both levodropropizine and dropropizine treatments (P < 0.001). Gastro-intestinal symptoms were mild in the two groups; somnolence was twice as frequent in the dropropizine group (10.3% vs 5.3%) and the difference is clinically relevant, though not statistically significant. Levodropropizine is as effective as an antitussive as dropropizine, but appears to carry a lower risk of daytime somnolence.

    Research has shown efficacy of melatonin treatment to advance sleep-wake rhythms in insomnia. In healthy adults, direction and magnitude of the phase shift depends on the timing of administration relative to the phase position of the circadian system. Therefore, in the present study we investigated whether in children with chronic sleep onset insomnia (SOI) efficacy of melatonin treatment in the early evening could be predicted from dim light melatonin onset (DLMO), a phase marker of the circadian system. We combined data of two previously published double blind, randomized, placebo-controlled trials in 110 participants, aged 6-12 years. Sleep was actigraphically estimated, and saliva collected, at baseline and in the third week of a 4-week treatment period with 5 mg melatonin or placebo at 18:00 or 19:00 hours. Primary outcome measures were pre- to post-treatment changes in dim light melatonin onset (DeltaDLMO), sleep onset (DeltaSO), sleep latency (DeltaSL), and total sleep duration (DeltaTSD). Melatonin advanced DLMO with +1:12 h (P < 0.001), SO with +0:42 h (P = 0.004), SL decreased with 25 min (P = 0.019), and TSD did not change significantly, as compared with placebo. In the melatonin-treated group, but not in the placebo-treated group, pretreatment DLMO was significantly related to DeltaDLMO [F(1, 29) = 7.28, P = 0.012] and DeltaSO [F(1, 25) = 7.72, P = 0.010]. The time interval between treatment administration and pretreatment DLMO (INT) was only significantly related to DeltaSO [F(1,26) = 5.40, P = 0.028]. The results suggest that in children with SOI, the efficacy of early evening melatonin to advance sleep onset and endogenous melatonin onset increases the later the pretreatment DLMO is.

    The efficacy of formalin and hydrogen peroxide to increase survival associated with external saprolegniasis on fingerlings of channel catfish Ictalurus punctatus was evaluated in four laboratory trials. Fungal epizootics were initiated according to procedures developed in a fungal-disease model. Fish were abraded with a dremel tool and then placed in an aerated static infection tank containing fungal-infected hemp seeds held in teaballs that were suspended in 100 L of water for 24 h (trials 1-3) or 6 h (trial 4). In the formalin trials, treatment regimens of 0, 82, and 166 mg/L (trial 1) or 0 and 83 mg/L (trial 2) were administered to channel catfish for 60 min once every other day for a total of three treatments (trial 1) or once daily for a total of seven treatments (trial 2). In the hydrogen peroxide trials, treatment regimens of 0, 75, and 102 mg/L (trial 3) or 0 and 75 mg/L (trial 4) were administered to channel catfish for 60 min once every other day for a total of three treatments. Each treatment regimen was tested in triplicate, with 10 fish per replicate. Formalin exposures of 83 (seven treatments; 33% survival) and 166 mg/L (three treatments; 63% survival) for 60 min significantly (P <= 0.01) increased channel catfish survival in comparison with controls (of which 3% and 13%, respectively, survived). In trial 4, hydrogen peroxide exposure of 75 mg/L (63% survival) for 60 min significantly (P <= 0.01) increased channel catfish survival in comparison with the untreated controls (13% survival). Formalin and hydrogen peroxide treatments were effective in increasing survival in channel catfish infected with fungus.

    Background: Diabetes Mellitus (DM) imposes restrictions on physical, emotional and social functioning of children and adolescents. Objectives: The aim of this study was to determine the impact of acceptance and commitment therapy (ACT) on perceived stress and special health self-efficacy in seven to fifteen-year-old children with DM. Patients and Methods: The present study was a clinical trial with a pretest-posttest control group design. The study population included all seven to fifteen-year-old patients who had referred to the Diabetes Mellitus Association of Tabriz, Iran, of whom 40 participants were selected using convenient sampling. They were randomly allocated to two matched groups (experimental and control). The experimental group participated in therapy sessions, while the control group did not receive any interventions. The research instruments were perceived stress and special health self-efficacy scales. Results: The multiple analysis of covariance (MANCOVA) results showed that the treatment was effective on variables of perceived stress and special health self-efficacy (P < 0.001). Conclusions: The ACT is effective for reducing perceived stress and increasing special health self-efficacy in children with DM. PMID:26288639

    Arterial stiffness has been observed in white American obese children, yet there are no data in American Indian youth, who are affected disproportionately by the cardiovascular consequences of childhood obesity and its accompanying risk factors. The purpose of this study was to determine the association of childhood overweight-obesity and cardiometabolic risk factors with arterial stiffness in South Dakota white American and American Indian children. Thirty-six (28 white American and 8 American Indian) children (age, 13 ± 1 years; grades 6-8) from a rural South Dakota elementary and middle school were studied: 18 had a healthy weight (body mass index (BMI), 19.5 ± 1.9 kg/m(2)) and 18 were overweight-obese (BMI, 26.8 ± 3.5 kg/m(2)). Arterial stiffness was assessed using applanation tonometry via pulse wave analysis to determine carotid-radial pulse wave velocity (crPWV) and aortic augmentation index (AIx). There were no differences (P = 0.94) in crPWV between healthy weight (7.1 ± 1.4 m/s) and overweight-obese (7.3 ± 1.0 m/s) children, even after controlling for risk factors. However, crPWV was markedly elevated (P = 0.002) in overweight-obese American Indian children (7.7 ± 1.1 m/s) compared with white American children (6.8 ± 0.5 m/s), and these differences remained after controlling for blood pressure and more severe obesity in the American Indians. An obesity-matched subgroup analysis indicated that crPWV (7.7 ± 1.1 vs 6.8 ± 0.4 m/s) remained significantly greater in the American Indians (P = 0.03). There were no between-group differences in aortic AIx. These findings indicate an adverse influence of American Indian ethnicity on arterial stiffening in children with elevated adiposity. Arterial stiffness in American Indian children may accelerate early adulthood vascular disease.

    Positive health outcomes are related to adults' religious congregational participation. For parents of children with chronic disease, structured daily care routines and/or strict infection control precautions may limit participation. For this exploratory study, we examined the relationship between congregational support and religious coping by parents of children with cystic fibrosis (CF) compared to parents for whom child health issues were not significant stressors. CF parents reported higher levels of emotional support from congregation members and use of religious coping. Within-group differences were found for CF parents by denominational affiliation. Congregational support for parents dealing with child chronic disease is important.

    Aim To assess the effect of combined use of chlorhexidine and fluoride varnish on the remineralization of incipient carious lesions in young children. Materials and methods Twenty caries-active children (80 lesions) were randomly divided into four groups and subjected to initial examination. Caries status was assessed visually and with the aid of DIAGNOdent. Baseline enamel biopsies were obtained. Subjects of groups I and II received fluoride and chlorhexidine varnish respectively. Group III received both fluoride and chlorhexidine varnish alternatively, for a period of 4 weeks. Group IV served as the control. At 3-month follow-up, the incipient lesions were assessed again with DIAGNOdent and enamel biopsy. Results Increased calcium, phosphate, and fluoride levels were noticed in groups I, II, III compared to group IV, at the 3-month follow-up (p < 0.001). Conclusion The combined therapy with fluoride and chlorhex-idine varnish may be considered an alternative therapy for early reversal of incipient lesions.

    Research shows that after training in the philosophy and practice of mindfulness, parents can mindfully attend to the challenging behaviors of their children with autism. Parents also report an increased satisfaction with their parenting skills and social interactions with their children. These findings were replicated and extended with 4 parents of children who had developmental disabilities, exhibited aggressive behavior, and had limited social skills. After mindfulness training, the parents were able to decrease aggressive behavior and increase their children's social skills. They also reported a greater practice of mindfulness, increased satisfaction with their parenting, more social interactions with their children, and lower parenting stress. Furthermore, the children showed increased positive and decreased negative social interactions with their siblings. We speculate that mindfulness produces transformational change in the parents that is reflected in enhanced positive behavioral transactions with their children.

    The aim of the present review was to clarify the efficacy of currently available potent antiresorptive agents for preventing fractures in Japanese patients with an increased fracture risk. PubMed was used to search the literature for randomized controlled trials (RCTs), with the following search terms: fracture, etidronate, alendronate, risedronate, minodronate, raloxifene, bazedoxifene and Japan. The inclusion criteria were papers written in English, ≥50 subjects per group and a study period of ≥1 year. Fourteen RCTs met these criteria. The efficacy of antiresorptive agents for preventing vertebral, nonvertebral and hip fractures was investigated. There was evidence that raloxifene reduced the incidence of clinical vertebral fractures, while etidronate, alendronate and minodronate (but not bazedoxifene) reduced the incidence of morphometric vertebral fractures in patients with postmenopausal or involutional osteoporosis. Head-to-head trials showed that alendronate and raloxifene had similar efficacy for preventing vertebral fractures in patients with postmenopausal osteoporosis, while risedronate was not inferior to etidronate for reducing the incidence of morphometric vertebral fractures in patients with involutional osteoporosis. Alendronate reduced the incidence of hip fractures in patients with Parkinson's disease, and risedronate reduced the incidence of nonvertebral fractures and hip fractures in patients with Alzheimer's disease or stroke. In conclusion, the present review confirmed the efficacy of etidronate, minodronate and raloxifene for the prevention of vertebral fractures, the efficacy of alendronate for vertebral and hip fractures, and the efficacy of risedronate for vertebral, nonvertebral and hip fractures in Japanese patients with an increased fracture risk.

  17. Engineering novel targeted nanoparticle formulations to increase the therapeutic efficacy of conventional chemotherapeutics against multiple myeloma

    NASA Astrophysics Data System (ADS)

    Ashley, Jonathan D.

    Multiple myeloma (MM) is a hematological malignancy which results from the uncontrolled clonal expansion of plasma cells within the body. Despite recent medical advances, this disease remains largely incurable, with a median survival of ˜7 years, owing to the development of drug resistance. This dissertation will explore new advances in nanotechnology that will combine the cytotoxic effects of small molecule chemotherapeutics with the tumor targeting capabilities of nanoparticles to create novel nanoparticle formulations that exhibit enhanced therapeutic indices in the treatment of MM. First, doxorubicin was surfaced conjugated onto micellar nanoparticles via an acid labile hydrazone bond to increase the drug accumulation at the tumor. The cell surface receptor Very Late Antigen-4 (VLA-4; alpha4beta1) is expressed on cancers of hematopoietic origin and plays a vital role in the cell adhesion mediated drug resistance (CAM-DR) in MM. Therefore, VLA-4 antagonist peptides were conjugated onto the nanoparticles via a multifaceted procedure to actively target MM cells and simultaneously inhibit CAM-DR. The micellar doxorubicin nanoparticles were able to overcome CAM-DR and demonstrated improved therapeutic index relative to free doxorubicin. In addition to doxorubicin, other classes of therapeutic agents, such as proteasome inhibitors, can be incorporated in nanoparticles for improved therapeutic outcomes. Utilizing boronic acid chemistry, bortezomib prodrugs were synthesized using a reversible boronic ester bond and then incorporated into liposomes. The different boronic ester bonds that could be potentially used in the synthesis of bortezomib prodrugs were screened based on stability using isobutylboronic acid. The liposomal bortezomib nanoparticles demonstrated significant proteasome inhibition and cytotoxicity in MM cells in vitro, and dramatically reduced the non-specific toxicities associated with free bortezomib while maintaining significant tumor growth

    Background It has been unclear whether relatively high cortisol and cortisone levels are related to overweight in childhood, parental body mass index (BMI), and family dietary habits. The aim of this study was to compare cortisol and cortisone levels in urine and saliva from overweight and normal children, as well as correlations between children’s BMI, parental BMI and family dietary behavior questionnaire score (QS). Material/Methods We analyzed the data from 52 overweight children and 53 age- and sex-matched normal-weight children aged 4–5 years. The concentrations of salivary cortisol (SF), salivary cortisone (SE), urinary cortisol (UF) and urinary cortisone (UE) were measured using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The family dietary behavior QS was answered by the parent mainly responsible for the family diet. Results Average cortisol and cortisone levels were significantly higher in overweight children. There was no significant difference in the ratio of cortisol to cortisone (Rcc) and the marker of 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) activities. The results displayed correlations among cortisol, cortisone, and Rcc. Positive correlations were weak-to-moderate between BMI and SF, SE, UF, and UE. There were correlations between BMI and maternal BMI (mBMI), and BMI was significantly associated with QS. Conclusions Our results suggest that cortisol and cortisone levels are associated with overweight in children, but the 11β-HSD2 activities showed no significant differences. Unhealthy family diet was associated with higher BMI, UF, and UE, and families with maternal overweight or obesity had a higher prevalence of children’s overweight or obesity. PMID:28179618

    Microtubule-poisoning drugs, such as Paclitaxel (or Taxol, PTX), are powerful and commonly used anti-neoplastic agents for the treatment of several malignancies. PTX triggers cell death, mainly through a mitotic arrest following the activation of the spindle assembly checkpoint (SAC). Cells treated with PTX slowly slip from this mitotic block and die by mitotic catastrophe. However, cancer cells can acquire or are intrinsically resistant to this drug, posing one of the main obstacles for PTX clinical effectiveness. In order to override PTX resistance and increase its efficacy, we investigated both the enhancement of mitotic slippage and the block of mitotic exit. To test these opposing strategies, we used physiological hyperthermia (HT) to force exit from PTX-induced mitotic block and the anaphase-promoting complex/cyclosome (APC/C) inhibitor, proTAME, to block mitotic exit. We observed that application of HT on PTX-treated cells forced mitotic slippage, as shown by the rapid decline of cyclin B levels and by microscopy analysis. Similarly, HT induced mitotic exit in cells blocked in mitosis by other antimitotic drugs, such as Nocodazole and the Aurora A inhibitor MLN8054, indicating a common effect of HT on mitotic cells. On the other hand, proTAME prevented mitotic exit of PTX and MLN8054 arrested cells, prolonged mitosis, and induced apoptosis. In addition, we showed that proTAME prevented HT-mediated mitotic exit, indicating that stress-induced APC/C activation is necessary for HT-induced mitotic slippage. Finally, HT significantly increased PTX cytotoxicity, regardless of cancer cells' sensitivity to PTX, and this activity was superior to the combination of PTX with pro-TAME. Our data suggested that forced mitotic exit of cells arrested in mitosis by anti-mitotic drugs, such as PTX, can be a more successful anticancer strategy than blocking mitotic exit by inactivation of the APC/C.

    Traditionally, oral corticosteroids (OCSs) have been the mainstay of treatment for acute wheezing episodes among preschool children with a history of recurrent wheezing. Although there is substantial evidence for the efficacy of OCSs as a treatment for asthma exacerbations in school-aged children and adolescents, recent clinical studies questioned the benefits of OCSs as a treatment for acute wheezing in preschool children. This review summarizes the current evidence on the efficacy of OCSs as a treatment for acute wheezing episodes among preschool age children with episodic wheezing, focusing on studies performed in three different settings: OCS treatment initiated by parents in the outpatient setting, OCS treatment initiated in the emergency department (ED), and OCS treatment among hospitalized preschool children. The results of most studies reviewed in this paper do not support the efficacy of OCS treatment among preschool children with recurrent wheezing. The heterogeneity of early childhood wheezing and asthma might be part of the explanation for lack of efficacy of this intervention noted in multiple studies.

    A nurse-coached exercise intervention for 10 people with tetraplegic spinal cord injuries was conducted over a period of 2 years at an accessible, community-based YMCA using an equipment especially designed for people with mobility issues and neurological deficits. In this single-subject design study, each participant completed three 3-hour exercise sessions a week for over 6 months. The purpose of the study was to determine what effects the program would have on increasing muscle strength, improving quality of life, and increasing self-efficacy after traditional outpatient therapy sessions were no longer available or affordable. The Sheehy Spinal Cord Injury Functional Improvement via Exercise Model was constructed at the conclusion of an unpublished pilot study and was tested in this study. Expectations of the model were that, if a person with a tetraplegic spinal cord injury participated in a coached program of exercise, muscle strength would increase and functional ability would improve, resulting in greater independence, a higher sense of self-efficacy, and a higher quality of life. Study results using a single-subject design of graph-trend analysis showed upward trajectories in muscle strength, quality of life, and self-efficacy in all study participants regardless of the length of time since his or her original injury. The results support the efficacy of this nurse-coached program for people with tetraplegic spinal cord injuries and validate the Sheehy Spinal Cord Injury Functional Improvement via Exercise Model.

    This retrospective study examined the efficacy and safety of zonisamide for Thai children and adolescents with intractable seizures. The medical records of 24 patients (13 male, 11 female), aged 2 to 18 years (median 11.5, mean 10.4) who received zonisamide were reviewed. The underlying illness, etiology of epilepsy, seizure types, previous and concomitant antiepileptic drugs, dosage, and adverse effects of the drug were collected. Zonisamide's efficacy was evaluated on the basis of seizure reduction rates. At final evaluation, 7 patients were still taking zonisamide from 4.7 to 10.3 mg/kg/d (median 8). One patient became seizure-free and the other 6 experienced favorable seizure control. The median duration of zonisamide therapy was 23.75 months (range 20.5-25 months). Minor adverse effects were reported in 41.6% of patients during the first 3 months of therapy. Zonisamide is an option for the treatment of intractable seizures with favorable seizure control in children and adolescents.

    In order to guide the antimalarial treatment policy of Somalia, we conducted therapeutic efficacy studies of routinely used antimalarial monotherapies as well as artemisinin-based combination therapies (ACTs) for uncomplicated malaria in three sentinel sites during 2003-2006. Therapeutic efficacy of chloroquine (CQ), amodiaquine (AQ) and sulfadoxine/pyrimetahmine (SP) monotherapies, and artesunate plus SP (AS+SP) or AQ (AS+AQ) were evaluated in children 6 months to 10 years old with uncomplicated malaria. For the assessment of the monotherapies, 2003 WHO protocol with 14-day follow-up was used while the 2005 WHO protocol with 28-day follow-up was used for testing the ACTs. Of the monotherapies, CQ performed very poorly with treatment failures varying from 76.5% to 88% between the sites. AQ treatment failure was low except for Janale site with treatment failure of 23.4% compared to 2.8% and 8% in Jamame and Jowhar, respectively. For SP, treatment failures from 7.8% to 12.2% were observed. A 28-day test of artemisinin-based combinations, AS+SP and AS+AQ, proved to be highly efficacious with cure rates of 98-100% supporting the choice of AS+SP combination as first line treatment for uncomplicated malaria for Somalia.

    This experiment was designed to study the Orff Approach--a child-centered, developmental approach to music education that aims to enrich the imagination through the acceleration of psychological activities. The study was conducted in children who had exhibited problematic behavior possibly due to economical or psychological issues; it aimed to determine whether the Orff Approach satisfies educational and treatment purposes and is an acceptable alternative in improving self-expression, self-efficacy, and social skills. The experiment involved 43 elementary school children in South Korean households with a monthly income of 100% below the average (according to the National Basic Living Security Act, South Korea's Ministry of Health and Welfare), and the results showed an increase of the chil-dren's self-expression, self-efficacy, and social skills after musical activities with the Orff Approach. Also, children interacted with the musical activities--according to the Orff Approach--like a game.They noted that they were able to explain their thoughts and emotions better; their relationships with friends improved, as well. Therefore, this research is significant because it shows that musical activities according to the Orff Approach have possibilities to be utilized as a program for children's psychological and emotional support.

    The EEG, or electroencephalogram, is a neurophysiological technique used to detect and record electrical activity in the brain. It is critical to the diagnosis and management of seizure disorders, such as epilepsy, as well as other neurological conditions. The EEG procedure is often not well tolerated by children with developmental disabilities because of anxiety about unfamiliar equipment, difficulty inhibiting motion, and tactile defensiveness. The inability of children with developmental disabilities to tolerate an EEG procedure is especially problematic because the incidence of epilepsy is considerably higher in children with disabilities. This clinical outcome study sought to determine the efficacy of using behavioral intervention to teach children with developmental disorders to cooperate with an EEG procedure. The behavioral training employed modeling, counterconditioning, escape extinction, and differential reinforcement-based shaping procedures. Results indicated that behavioral training is successful in promoting EEG compliance without restraint, anesthesia, or sedation. PMID:18348911

    Isolation of Staphylococcus aureus with minimum inhibitory concentrations, 1 to 2 mg/L, suggests increasing vancomycin trough ranges, from 10 to 20 mg/L or even higher. Vancomycin troughs from 604 treatment courses from 560 patients with suspected or actual Gram-positive infection were analyzed with focus on potential toxicity/efficacy. Trough concentrations were required to be drawn within 15 to 45 minutes before the administration of at least the third vancomycin dose. Patients were retrospectively evaluated for their total daily dose and milligrams per kilograms per vancomycin dose. Data on the duration of vancomycin therapy, days to a normal temperature, and white blood cells were obtained. Data were stratified by trough concentration as <5, 5 to 10, and >10 mg/L to determine whether there was any relationship between response and trough concentration. Demographic data were obtained in 560 patients with 604 vancomycin treatment courses. For 361 patients with 379 separate treatment courses of vancomycin therapy no other nephrotoxic antimicrobial agent had been used. The greatest risk of vancomycin nephrotoxicity correlated with the duration of treatment. Using the log time to normal temperature, white blood cell count, heart rate, outcome from vancomycin therapy was assessed and no relationship could be demonstrated for the three vancomycin trough strata using analysis of variance (F < 2.62 for all parameters; p > .05). These data indicate that vancomycin trough elevation may not guarantee treatment success and that there may be no real benefit from higher vancomycin trough concentrations in thermal injury patients with burns <20% TBSA.

    Penile trabecular smooth muscle tone, a major determinant of erectile function, is highly regulated by numerous inter- and intracellular pathways. The interaction between pathways mediating contraction and relaxation has not been studied in detail. To this end, we investigated the functional effects of alpha adrenergic receptor blockade with phentolamine and its interaction with vasodilators (sildenafil, vasoactive intestinal polypeptide (VIP) and PGE1) that elevate cyclic nucleotides on penile cavernosal smooth muscle contractility. In organ bath preparations of cavernosal tissue strips contracted with phenylephrine, phentolamine significantly enhanced relaxation induced by sildenafil, VIP and PGE1. Sildenafil, VIP or PGE1 also significantly enhanced relaxation induced by phentolamine in cavernosal tissue strips contracted with phenylephrine. To study the effects of alpha adrenergic receptor blockade and modification of cyclic nucleotide metabolism during active neurogenic input, cavernosal tissue strips in organ bath preparations were contracted with the non-adrenergic agonist endothelin-1 and subjected to electrical field stimulation (EFS) in the absence or presence of phentolamine and/or sildenafil. EFS (5-40Hz) typically caused biphasic relaxation and contraction responses. Phentolamine alone enhanced relaxation and reduced or prevented contraction to EFS. Sildenafil enhanced relaxation to EFS at lower frequencies (< or = 5 Hz). The combination of phentolamine and sildenafil enhanced EFS-induced relaxation at all frequencies tested. EFS, in the presence of 10 nM phentolamine and 30 nM sildenafil, produced enhanced relaxation responses which were quantitatively similar to those obtained in the presence of 50 nM sildenafil alone. Thus, blockade of alpha-adrenergic receptors with phentolamine increases the efficacy of cyclic nucleotide-dependent vasodilators. Furthermore, phentolamine potentiates relaxation and attenuates contraction in response to endogenous

    Two meta-analyses were conducted to quantify the benefit of combining alpha-IFN to 5FU in advanced colorectal cancer in terms of tumour response and survival. Analyses were based on a total of 3254 individual patient data provided by principal investigators of each trial. The meta-analysis of 5FU +/- LV vs. 5FU +/- LV + alpha-IFN combined 12 trials and 1766 patients. The meta-analysis failed to show any statistically significant difference between the two treatment groups in terms of tumour response or survival. Overall tumour response rates were 25% for patients receiving no alpha-IFN vs. 24% for patients receiving alpha-IFN (relative risk, RR = 1.02), and median survivals were 11.4 months for patients receiving no alpha-IFN vs. 11.5 months for patients receiving alpha-IFN (hazard ratio, HR = 0.95). The meta-analysis of 5FU + LV vs. 5FU + alpha-IFN combined 7 trials, and 1488 patients. This meta-analysis showed an advantage for 5FU + LV over 5FU + alpha-IFN which was statistically significant in terms of tumour response (23% vs. 18%; RR = 1.26;P = 0.042), and of a borderline significance for overall survival (HR = 1.11;P = 0.066). Metastases confined to the liver and primary rectal tumours were independent favourable prognostic factors for tumour response, whereas good performance status, metastases confined to the liver or confined to the lung, and primary tumour in the rectum were independent favourable prognostic factors for survival. We conclude that alpha-IFN does not increase the efficacy of 5FU or of 5FU + LV, and that 5FU + alpha-IFN is significantly inferior to 5FU + LV, for patients with advanced colorectal cancer.

    Abstract Objective: To assess the efficacy of oral ketamine versus oral midazolam for sedation during laceration repair at a pediatric emergency department. Methods: Children between 1 and 10 years requiring laceration repair were randomly assigned to 2 groups, treated either with oral midazolam (0.7 mg/kg) or with oral ketamine (5 mg/kg). Main outcomes measured were level of pain during local anesthesia, as assessed by the parent on a 10-cm visual analog scale (VAS) and the number of children who required intravenous sedation. Secondary outcomes included VAS by physician, pain assessment by child, maximal sedation depth assessed by the University of Michigan Sedation Scale, time until University of Michigan Sedation Scale 2 or more, general satisfaction of a parent and treating physician, length of procedure, total sedation time, and the incidence of any adverse events. Results: Sixty-eight children were recruited of which 33 were girls. Average age was 5.08 ± 2.14 years. Thirty-seven children were treated with ketamine and 31 with midazolam. Parent-assessed VAS in ketamine treated patients was 5.07 ± 0.75 compared with 3.68 ± 0.7 in midazolam treated patients [mean difference = 1.39 95% confidence interval (CI) –0.47 to 3.26]. Twelve (32%) of the children treated with ketamine required the addition of IV sedation compared to only 2 children (6%) of the children treated with midazolam [odds ratio (adjusted for age and gender) 6.1, 95% CI: 1.2 to 30.5]. The rest of the measured variables were similar between the groups, with no statistical significance. Discussion: No difference in the level of pain was found between ketamine and midazolam treated patients. Compared with oral midazolam (0.7 mg/kg), oral ketamine (5 mg/kg) was associated with higher rates of sedation failure, and thus is not recommended as a single agent for oral sedation in children requiring laceration repair.

    OBJECTIVE: To test the efficacy of an innovative family-based intervention for overweight preschool-aged children and overweight parents conducted in the primary care setting. METHODS: Children with BMI ≥85th percentile and an overweight parent were randomized to intervention or information control (IC). Trained staff delivered dietary and physical/sedentary activities education to parents over 6 months (10 group meetings and 8 calls). Parents in the intervention received also behavioral modification. An intention-to-treat analysis was performed by using mixed analysis of variance models to test changes in child percent over BMI (%OBMI) and z-BMI and to explore potential moderators of group differences in treatment response. RESULTS: Ninety-six of 105 randomized families started the program: 46 children (31 girls/15 boys) in the intervention and 50 (33 girls/17 boys) in the IC, with 33 and 39 mothers and 13 and 11 fathers in intervention and IC, respectively. Baseline characteristics did not differ between groups. Children in the intervention group had greater %OBMI and z-BMI decreases at 3 and 6 months compared with those assigned to IC (P < .0021). A greater BMI reduction over time was also observed in parents in the intervention compared with parents assigned to IC (P < .0001). Child %OBMI and parent BMI changes were correlated (r = .31; P = .003). Children with greater baseline %OBMI were more likely to have a greater %OBMI decrease over time (P = .02). CONCLUSIONS: Concurrently targeting preschool-aged overweight youth and their overweight parents for behavioral weight control in a primary care setting reduced child %OBMI and parent BMI, with parent and child weight changes correlating.

    Several non-stimulant medications have been used in the treatment of attention deficit hyperactivity disorder (ADHD). Atomoxetine, was introduced in 2002. The safety and efficacy of atomoxetine in the treatment of ADHD for children, adolescents, and adults has been evaluated in over 4000 patients in randomized controlled studies and double blinded studies as well as in recent large longitudinal studies. This paper provides an updated summary of the literature on atomoxetine, particularly in relation to findings on the short- and long-term safety of atomoxetine in children and adolescents arising from recent large longitudinal cohort studies. Information is presented about the efficacy, safety, and tolerability of this medication. PMID:23641171

    The authors used a large sample of children (N ≈ 7,400) participating in the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) to estimate kindergarten children's academic achievement growth trajectories in reading and mathematics. The authors were particularly interested in whether the growth trajectories of children with learning disabilities (LD) or speech language impairments (SLI)--as well as those of other groups of children--were consistent with a cumulative or compensatory developmental cycle. Both LD and SLI children displayed significantly lower levels of kindergarten reading achievement than nondisabled children. However, and over the subsequent 5 years of elementary school, only children with SLI lagged increasingly behind nondisabled peers in their reading skills growth. The authors observed a different pattern for mathematics achievement. Children with LD, but not SLI, lagged increasingly behind nondisabled children in their mathematics skills growth. The authors also observed some consistency in "poor-get-poorer" effects across reading and mathematic achievement for additional population subgroups. Those kindergarten children who were from lower socioeconomic status families, who were African American, and who more frequently displayed learning-related behavior problems initially had lower levels of reading and mathematics achievement and also lagged increasingly behind in their acquisition of these skills over time. Some groups of children, including those with SLI, experience a cumulative rather than a compensatory cycle of achievement growth.

    OBJECTIVE Nocturnal hypoglycemia can cause seizures and is a major impediment to tight glycemic control, especially in young children with type 1 diabetes. We conducted an in-home randomized trial to assess the efficacy and safety of a continuous glucose monitor–based overnight predictive low-glucose suspend (PLGS) system. RESEARCH DESIGN AND METHODS In two age-groups of children with type 1 diabetes (11–14 and 4–10 years of age), a 42-night trial for each child was conducted wherein each night was assigned randomly to either having the PLGS system active (intervention night) or inactive (control night). The primary outcome was percent time <70 mg/dL overnight. RESULTS Median time at <70 mg/dL was reduced by 54% from 10.1% on control nights to 4.6% on intervention nights (P < 0.001) in 11–14-year-olds (n = 45) and by 50% from 6.2% to 3.1% (P < 0.001) in 4–10-year-olds (n = 36). Mean overnight glucose was lower on control versus intervention nights in both age-groups (144 ± 18 vs. 152 ± 19 mg/dL [P < 0.001] and 153 ± 14 vs. 160 ± 16 mg/dL [P = 0.004], respectively). Mean morning blood glucose was 159 ± 29 vs. 176 ± 28 mg/dL (P < 0.001) in the 11–14-year-olds and 154 ± 25 vs. 158 ± 22 mg/dL (P = 0.11) in the 4–10-year-olds, respectively. No differences were found between intervention and control in either age-group in morning blood ketosis. CONCLUSIONS In 4–14-year-olds, use of a nocturnal PLGS system can substantially reduce overnight hypoglycemia without an increase in morning ketosis, although overnight mean glucose is slightly higher.

    This study was conducted to investigate the associations of scores on four self-regulation subscales identified by Nakata and Shiomi in 1998 with those on personality traits measured on the Shimoda Personality Inventory and self-efficacy with 123 Japanese elementary school children. Scores on the self-regulation subscales had significant positive correlations with scores on immodithymic and syntonic traits, and significant negative correlations with scores on schizothymic, nervous, and uncertain traits. Correlations with self-efficacy were also positive and significant. From these results higher scorers on self-regulation may have more positive personality traits and higher self-efficacy scores.

    Children exposed to intimate partner violence (IPV) are at high risk for adjustment problems, especially internalizing disorders. Few evidence-based interventions are available to address internalizing behavior problems in this population. An efficacy trial compared outcomes for 4-6 year old children randomly assigned to a program designed to address the effects of exposure to IPV with those allocated to a waitlist comparison condition. Mothers (N = 120) and children from the United States and Canada were assessed at baseline, 5 weeks later (post-intervention) and at 8-month follow-up. The evaluation compared rates of change over time for child internalizing problems. Results were analyzed using both intent-to-treat (ITT) and per-protocol (PP) approaches. ITT analyses indicated the program reduced internalizing problems for girls at follow-up. PP analyses indicated the program reduced internalizing problems for both boys and girls at post-intervention. In this study, child internalizing problems were significantly reduced through an intervention for the mother and the child.

    Abstract Purpose: Educational interventions to reduce Lyme disease (LD) among at-risk school children have had little study. The purpose of this study was to evaluate whether a short in-class LD education program based on social learning theory and the Health Belief Model (HBM) impacted a child's knowledge, attitude, and preventive behavior. Methods: Students in grades 2–5 in 19 elementary schools were selected in an area that was highly endemic for LD. The children received an educational intervention or were on a wait list as controls. Their knowledge, attitudes, and self-reported preventive behaviors were surveyed before implementing the program and 1 year later. General linear regression analyses adjusting for age, gender, and baseline variables were used to measure the impact of the intervention. Results: There were 3570 participants in the study: 1562 received the intervention, and 2008 were controls. The mean age for both groups was 9.1 years, with 53% women in the intervention group and 50% women in the control group. The children in the intervention group increased their overall knowledge of LD more than the children in the control group (overall knowledge score improvement, mean difference (SD) 1.38 (1.3) vs. 0.36 (1.3) p < 0.0001). All children in classes receiving the intervention reported an increase in precautionary behavior, positive attitude toward taking precautions, and self-efficacy compared with the wait list controls. Two LD cases were confirmed during the follow-up period, one in the intervention group and one in the controls. Conclusions: These findings demonstrate that a short in-class educational program that includes elements of the HBM, including: (1) awareness and knowledge about the disease, (2) benefits of preventive behavior, and (3) confidence in ability to perform preventive behaviors can improve knowledge, attitude, and self-reported precautionary behavior among at-risk children. www.clinicaltrials.gov: NCT00594997 PMID

    Attention-deficit hyperactivity disorder (ADHD) is a common neuropsychiatric disorder that is often diagnosed during childhood, but has also increasingly been recognized to occur in adults. Importantly, up to 52% of children (including adolescents) and 87% of adults with ADHD also have a comorbid psychiatric disorder. The presence of a comorbid disorder has the potential to impact diagnosis and could affect treatment outcomes. Atomoxetine is a nonstimulant treatment for ADHD. Despite numerous published studies regarding efficacy of atomoxetine in the treatment of ADHD in patients with comorbid disorders, there is limited information about the impact of individual common comorbid disorders on the efficacy of atomoxetine for ADHD, especially with regard to adults. Moreover, a cumulative review and assessment of these studies has not been conducted. For this reason, we performed a literature review to find, identify, and cumulatively review clinical studies that examined the efficacy of atomoxetine in the treatment of patients with ADHD and comorbid psychiatric disorders. We found a total of 50 clinical studies (37 in children; 13 in adults) that examined the efficacy of atomoxetine in patients with ADHD and a comorbid disorder. The comorbidities that were studied in children or in adults included anxiety, depression, and substance use disorder. Overall, the presence of comorbidity did not adversely impact the efficacy of atomoxetine in treatment of ADHD symptoms in both patient populations. In the studies identified and assessed in this review, atomoxetine did not appear to exacerbate any of the comorbid conditions and could, therefore, be an important therapy choice for the treatment of ADHD in the presence of comorbid disorders.

    Attention-deficit hyperactivity disorder (ADHD) is a common neuropsychiatric disorder that is often diagnosed during childhood, but has also increasingly been recognized to occur in adults. Importantly, up to 52% of children (including adolescents) and 87% of adults with ADHD also have a comorbid psychiatric disorder. The presence of a comorbid disorder has the potential to impact diagnosis and could affect treatment outcomes. Atomoxetine is a nonstimulant treatment for ADHD. Despite numerous published studies regarding efficacy of atomoxetine in the treatment of ADHD in patients with comorbid disorders, there is limited information about the impact of individual common comorbid disorders on the efficacy of atomoxetine for ADHD, especially with regard to adults. Moreover, a cumulative review and assessment of these studies has not been conducted. For this reason, we performed a literature review to find, identify, and cumulatively review clinical studies that examined the efficacy of atomoxetine in the treatment of patients with ADHD and comorbid psychiatric disorders. We found a total of 50 clinical studies (37 in children; 13 in adults) that examined the efficacy of atomoxetine in patients with ADHD and a comorbid disorder. The comorbidities that were studied in children or in adults included anxiety, depression, and substance use disorder. Overall, the presence of comorbidity did not adversely impact the efficacy of atomoxetine in treatment of ADHD symptoms in both patient populations. In the studies identified and assessed in this review, atomoxetine did not appear to exacerbate any of the comorbid conditions and could, therefore, be an important therapy choice for the treatment of ADHD in the presence of comorbid disorders.

    Fruit and vegetable consumption represents a nutritional goal to prevent obesity and chronic illness. To change dietary behaviors, people must be motivated to do so, and they must translate their motivation into actual behavior. The present experiment aims at the psychological mechanisms that support such changes, with a particular focus on dietary self-efficacy and planning skills. A randomized controlled trial compared a theory-based psychological intervention with a health education session in 114 participants. Dependent variables were fruit and vegetable consumption, intention to consume more fruit and vegetables, planning to consume more, and dietary self-efficacy, assessed before the intervention, 1 week afterwards, and at 6-week follow up. Significant group by time interactions for all four dependent variables documented superior treatment effects for the psychological intervention group, with substantially higher scores at posttest and follow-up for the experimental group, although all students benefited from participation. To identify the contribution of the main intervention ingredients (self-efficacy and planning), regression analyses yielded mediator effects for these two factors. A social-cognitive intervention to improve fruit and vegetable consumption was superior to a knowledge-based education session. Self-efficacy and planning seem to play a major role in the mechanisms that facilitate dietary changes.

  13. Changes in self-efficacy for exercise and improved nutrition fostered by increased self-regulation among adults with obesity.

    Annesi, James J; Johnson, Ping H; McEwen, Kristin L

    2015-10-01

    Behavioral theory suggests that treatments that increase participants' use of self-regulatory skills and/or their feelings of ability (self-efficacy) will improve exercise and nutrition behaviors. In addition, psychosocial factors associated with increased exercise may carry over to improved eating. Self-regulation might enhance self-efficacy through feelings of ability to manage barriers to maintaining weight-loss behaviors. Sedentary adults with severe or morbid obesity (M age = 43 years; M BMI = 40.1 kg/m(2)) participated in a 6-month study within a community-based YMCA center. We randomly assigned participants to one of the two groups that incorporated the same cognitive-behavioral support of exercise paired with methods for controlled, healthy eating emphasizing either (a) self-efficacy (n = 138), or (b) self-regulation (n = 136) methods. Mixed model repeated measures ANOVAs indicated significant improvements in exercise- and eating-related self-regulation over 3 months, and exercise- and eating-related self-efficacy over 6 months. The Self-Regulation Treatment Group demonstrated greater improvements in self-regulation for eating and fruit and vegetable intake than the Self-Efficacy Group. Regression analyses indicated that for both exercise and eating, self-regulation change significantly predicted self-efficacy change. In separate equations, changes in exercise and fruit and vegetable intake mediated those relationships, and change in self-efficacy and the corresponding behavioral changes demonstrated reciprocal, mutually reinforcing, relationships. There was evidence of carry-over, or generalization, of both self-regulation and self-efficacy changes from an exercise context to an eating context. We discussed findings in terms of leveraging self-regulation to improve self-efficacy, and provide a rationale for why exercise is the strongest predictor of success with weight loss. Results may be used to inform future behavioral weight

  14. Synergism between carvacrol or thymol increases the antimicrobial efficacy of soy sauce with no sensory impact.

    Here, we examined the antimicrobial effects of soy sauce containing essential oils (EOs) against Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes at 22°C and 4°C. To screen a variety of combined effects, soy sauce was mixed with six different EOs (carvacrol, thymol, eugenol, trans-cinnamaldehyde, β-resorcylic acid, and vanillin), each at a concentration of 1mM for 10 min. None of the oils showed bactericidal activity when used alone. Soy sauce combined with carvacrol and thymol induced the greatest antibacterial activity against all tested bacteria; therefore, these oils were further tested at 0.25, 0.5, and 1mM (0.0039%, 0.0078%, and 0.0157%) for 1, 5, and 10 min at 4°C and 22°C. In addition, sensory evaluation of soy sauce containing each EO at 0.25, 0.5, 1, and 2mM was performed using the nine point hedonic test. Carvacrol or thymol (1mM) eliminated all the test bacteria (initial population, 7.0-7.5logCFU/ml) in 1-5 min at 22°C and within 10 min at 4°C. L. monocytogenes was slightly more tolerant at 4°C, which may be attributable to the ability of the cell membrane to adapt to low temperatures. The sensory scores for soy sauce containing EOs were not significantly different from that of soy sauce without EOs (P>0.05). The stability of EO efficacy in soy sauce was also verified. These results suggest that carvacrol and thymol act synergistically with other factors present in soy sauce to increase antimicrobial activity against major foodborne pathogens at both 4°C and 22°C. The synergism may be attributable to the combination of factors (mainly high salt concentration and low pH imparted by organic acids) present in soy sauce and the membrane attacking properties of carvacrol and thymol. This method will facilitate the production of microbiologically safe soy sauce, soy sauce-based marinades, and various marinated foods.

    Although the strong link between maternal education and children's outcomes is one of the most well-established findings in developmental psychology (Reardon, 2011; Sirin, 2005), less is known about how young, low-income children are influenced by their mothers completing additional education. In this research, longitudinal data from the Head Start Impact Study were used to explore the associations between increases in maternal education and Head Start eligible children's cognitive skills and behavioral problems in 1st grade. Propensity score weighting was used to identify a balanced comparison group of 1,362 children whose mothers did not increase their education between baseline (when children were aged 3 or 4) and children's kindergarten year, who are similar on numerous covariates to the 262 children whose mothers did increase their education. Propensity-score weighted regression analyses indicated that increases in maternal education were positively associated with children's standardized cognitive scores, but also with higher teacher-reported externalizing behavioral problems in 1st grade. The increases in externalizing behavioral problems were larger for children whose mothers had less than a college degree at baseline.

    Perinatal stroke causes cerebral palsy and lifelong disability. Specific diseases are definable but mechanisms are poorly understood. Evidence suggests possible associations between arterial perinatal stroke and prothrombotic disorders but population-based, controlled, disease-specific studies are limited. Understanding thrombophilia in perinatal stroke informs pathogenesis models and clinical management. We conducted a population-based, prospective, case-control study to determine the association of specific perinatal stroke diseases with known thrombophilias. Children with idiopathic, MRI-classified neonatal arterial ischemic stroke (NAIS), arterial presumed perinatal ischemic stroke (APPIS), or fetal periventricular venous infarction (PVI) were recruited. Standardized thrombophilia evaluations were performed after 12 months of age on stroke cases and controls including quantified protein C and S, antithrombin, factors VIII/IX/XI, fibrinogen, lipoprotein(a), homocysteine, lupus anticoagulant, anticardiolipin antibodies and genotyping of factor V Leiden (FVL), factor II G20210A (FII), and MTHFR C677T. A total of 212 children were studied: 46 NAIS, 34 APPIS, 55 PVI, and 77 controls (53% male, median 4.8 years). Of 14 parameters, no differences were observed in 12 including all common thrombophilias. Mean prothrombin time was shorter in arterial strokes (p<0.001). Rates of antiphospholipid antibodies were low, comparable to controls, and resolved on repeat testing. FVL and FII rates were comparable to population norms. Total number of possible abnormalities did not differ between cases and controls. Our prospective, population-based, controlled, disease-specific study suggests minimal association between perinatal stroke and thrombophilia. This does not exclude the possibility of disordered coagulation at the time of stroke but suggests testing in childhood is not indicated.

    Background Some researches have shown the association between iron deficiency and migraine headache in adults. The aim of present study was to evaluate efficacy of ferrous sulfate treatment on migraine headaches of 5-15 years old migraineur children with iron deficiency. Materials and Methods In a quasi- experimental study, monthly frequency, severity, duration and disability of headaches of 5-15 years old migraineur children that prophylactic therapy was indicated in them and had iron deficiency who were referred to Pediatric Neurology Clinic of Shahid Sadoughi University of Medical Sciences, Yazd, Iran between 2013 and 2015 and were treated with 2mg/kg/day topiramate plus 4mg/kg/day of ferrous sulfate for three consecutive months, were evaluated and headache characteristics before and after treatment were compared. Results In this study, 98 children with mean age of 9.72±3.19 were evaluated that 31children (31.6%) had iron deficiency. Monthly frequency (22.89±7.18 vs.14.5±4.56, P= 0.02), severity score (8.12± 1.76 vs. 5.03±1.15, P= 0.02) and disability score of headache (38.23±10.7vs. 30.12±7.46, P= 0.03) were more in children with iron deficiency. Iron therapy was effective in decreasing of monthlyfrequency 22.89± 7.18 vs. 10.13±4.51, P = 0.001), severity score (8.12±1.76 vs. 5.11±1.62, P =0.001), duration (2.14±1.23 vs.1.14±1.01, P= 0.001) and disability score of headache (38.23±10.7 vs. 22.87±8.65, P= 0.01). Conclusion In children, iron deficiency increased monthly frequency, severity and disability of migraine headache and ferrous sulfate can be used as a safe and effective drug in migraine prophylaxis.

    Routinely in the clinical practice, children affected by migraine without aura (MwA) tend to exhibit severe and persistent difficulties within cognitive processes such as attention, memory, and visual–motor integration (VMI) skills. The aim of this study was to assess the visual–spatial and visual–motor abilities among a sample of children with MwA and the effects of a specific computerized training. The study population was composed of 84 patients affected by MwA (39 girls and 45 boys; mean age: 8.91±2.46 years), and they were randomly divided into two groups (group A and group B) comparable for age (P=0.581), gender (P=0.826), socioeconomic status (SES), migraine frequency (P=0.415), and intensity (P=0.323). At baseline (T0), the two groups were comparable for movement assessment battery for children (M-ABC) and VMI performances. After 6 months of treatment (T1), group A showed lower scores in the dexterity item of M-ABC test (P<0.001) and higher scores in M-ABC global performance centile (P<0.001) and total (P<0.001), visual (P=0.017), and motor (P<0.001) tasks of VMI test than group B. Moreover, at T1, group A showed higher scores in total (P<0.001) and motor (P<0.001) tasks of VMI test and in M-ABC global performance centile (P<0.001) and lower scores in the dexterity item of M-ABC test (P<0.001) than at T0. Group B showed, at T1, performances comparable to T0 for all evaluations. As reported by recent studies about alteration MwA among children in motor abilities, our study confirmed these difficulties and the efficacy of a specific software training, suggesting a new rehabilitative proposal in childhood.

    2011-01-01

    The objective of the present study was to estimate the clinical efficacy of local antibacterial therapy in the children presenting with sinusitis. The study included a total of 104 patients allocated to 2 groups. In one of them, the patients underwent therapeutic and diagnostic punctures of the maxillary sinuses to obtain the material for subsequent microbiological analysis and to administer antibiotics into the sinuses. The results of the study give evidence that local application of antibacterial agents in combination with mucolytic drugs is at least as efficient for the treatment of acute maxillary sinusitis as the traditional methods for the management of the same conditions with the use of systemic antibiotics. The study confirmed the expediency of using the puncture technique for the treatment of patients with acute inflammatory process in maxillary sinuses.

    1995-10-01

    This paper reports on the effect of using an interactive and child-initiated microcomputer program (Alpha) when teaching three groups of children (N = 30) reading and communications skills: (a) 11 children with autism (M chronological age, CA = 9:4 years), (b) 9 children with mixed handicaps (M CA = 13:1), and (c) 10 normal preschool children (M CA = 6:4 years). Their mental age varied from 5:8 years to 6:9 years and all children received computer instruction supplementary to their regular reading and writing activities. Tests of reading and phonological development were carried out at the onset of the training (Start), at the end (Post 1), and at a follow-up evaluation (Post 2). In addition, video observations of the childrens' verbal and nonverbal communication were added at Start and Post 1. The children with autism increased both their word reading and their phonological awareness through the use of the Alpha program. Clearly significant gains were observed during the intervention, but none during the follow-up period. A similar but weaker pattern is observed for the children with mixed handicaps. In contrast, the normal preschool children increased their scores regardless of the program. Analyses of the children's classroom behavior indicate that the intervention succeeded in stimulating verbal expressions among the children with autism and mixed handicap. A significant increase in enjoyment was also noted for the children with autism. It is concluded that the intervention with a motivating multimedia program might stimulate reading and communication in children with various developmental disabilities, but that such interventions must be individually based and include both detailed planning and monitoring from teachers, and parents, as well as from clinicians in charge.

    Abstract Purpose: To compare fluoroscopy duration, radiation dose, and efficacy of two ultrasound stone localization systems during extracorporeal shockwave lithotripsy (SWL) treatment. Patients and Methods: Monocentric prospective data were obtained from patients consecutively treated for renal stones using the Sonolith® i-sys (EDAP TMS) lithotripter, with fluoroscopy combined with ultrasound localization using an “outline” Automatic Ultrasound Positioning Support (AUPS) (group A), or the “free-line” Visio-Track (VT) (EDAP-TMS) hand-held three-dimensional ultrasound stone locking system (group B). Efficacy rate was defined as the within-groups proportion stone free or with partial stone fragmentation not needing additional procedures. Statistical analysis used Pearson chi-square tests for categoric variables, nonparametric Mann-Whitney tests for continuous variables, and linear regression for operator learning curve with VT. Continuous variables were reported as median (range) values. Results: Patients in group A (n=73) and group B (n=81) were comparable in baseline characteristics (age, kidney stone size, others) and in SWL application (duration, number of shocks, energy [Joules]). During SWL, the median (range) duration (seconds) of radiation exposure was 159.5 (0–690) in group A and 3.5 (0–478) in group B (P<0.001) and irradiation dose (mGy.cm2), 10598 (0–54843) in group A and 163 (0–13926) in group B (P<0.001). Fluoroscopy time significantly decreased with operator experience using VT. The efficacy rate was 54.5% in group A and 79.5% in group B (P=0.001). Conclusion: VT significantly reduced fluoroscopy use during SWL and the duration and dose of patient exposure to ionizing radiation. Stone treatment efficacy was significantly greater with VT mainly because of a better real-time monitoring of the stone. PMID:26133199

    The RV144 trial demonstrated 31% vaccine efficacy at preventing human immunodeficiency virus (HIV)-1 infection. Antibodies against the HIV-1 envelope variable loops 1 and 2 (Env V1 and V2) correlated inversely with infection risk. We proposed that vaccine-induced immune responses against V1/V2 would have a selective effect against, or sieve, HIV-1 breakthrough viruses. A total of 936 HIV-1 genome sequences from 44 vaccine and 66 placebo recipients were examined. We show that vaccine-induced immune responses were associated with two signatures in V2 at amino acid positions 169 and 181. Vaccine efficacy against viruses matching the vaccine at position 169 was 48% (confidence interval 18% to 66%; P = 0.0036), whereas vaccine efficacy against viruses mismatching the vaccine at position 181 was 78% (confidence interval 35% to 93%; P = 0.0028). Residue 169 is in a cationic glycosylated region recognized by broadly neutralizing and RV144-derived antibodies. The predicted distance between the two signature sites (21 ± 7 Å) and their match/mismatch dichotomy indicate that multiple factors may be involved in the protection observed in RV144. Genetic signatures of RV144 vaccination in V2 complement the finding of an association between high V1/V2-binding antibodies and reduced risk of HIV-1 acquisition, and provide evidence that vaccine-induced V2 responses plausibly had a role in the partial protection conferred by the RV144 regimen.

    This article reports on the influence of neighborhood-level deprivation and collective efficacy on children’s antisocial behavior between the ages of 5 and 10 years. Latent growth curve modeling was applied to characterize the developmental course of antisocial behavior among children in the E-Risk Longitudinal Twin Study, an epidemiological cohort of 2,232 children. Children in deprived versus affluent neighborhoods had higher levels of antisocial behavior at school entry (24.1 vs. 20.5, p < .001) and a slower rate of decline from involvement in antisocial behavior between the ages of 5 and 10 (−0.54 vs. −0.78, p < .01). Neighborhood collective efficacy was negatively associated with levels of antisocial behavior at school entry (r =−.10, p < .01) but only in deprived neighborhoods; this relationship held after controlling for neighborhood problems and family-level factors. Collective efficacy did not predict the rate of change in antisocial behavior between the ages of 5 and 10. Findings suggest that neighborhood collective efficacy may have a protective effect on children living in deprived contexts. PMID:19586172

    Background: Previous research demonstrated that Machiavellian beliefs are linked with bully/victim problems at school. However, Machiavellianism was treated as a single construct and not as multidimensional. Children's perceptions of self-efficacy in both social and academic domains have been related to conflictual peer interactions but not…

    To evaluate the safety and efficacy of combining Endostar antiangiogenic therapy with neoadjuvant chemotherapy for the treatment of stage IIIA (N2) NSCLC, we conducted a randomized, controlled, open-label clinical study of 30 NSCLC patients. Patients were randomly assigned to the test or control groups, which received either two cycles of an NP neoadjuvant chemotherapy regimen combined with Endostar or the NP regimen alone, respectively, at a 2:1 ratio. Efficacy was assessed after 3 weeks, and surgical resection occurred within 4 weeks, in the 26 patients who successfully completed treatment. While total response rates (RR) and clinical benefit rates (CBR) did not differ between the experimental groups, total tumor regression rates (TRR) were higher in the test group than in the control group. Median DFS and OS also did not differ between the test and control groups. Clinical perioperative indicators, including intraoperative blood loss, number of dissected lymph node groups, duration of postoperative indwelling catheter use, and time to postoperative discharge, were comparable in the test and control groups. Finally, hematological and non-hematological toxicities and postoperative pathological indicators, including down-staging ratio, complete resection ratio, and metastatic lymph node ratio, also did not differ between the groups. Overall, combining Endostar with NP neoadjuvant chemotherapy increased therapeutic efficacy without increasing adverse effects in stage IIIA-N2 NSCLC patients. This study is registered with ClinicalTrials.gov (number NCT02497118). PMID:27566586

    In social cognitive theory, self-efficacy is domain-specific. An alternative model, the cross-domain influence model, would predict that self-efficacy beliefs in one domain might influence performance in other domains. Research has also found that children who receive special instruction are not good at estimating their performance. The aim was to test two models of how self-efficacy beliefs influence achievement, and to contrast children receiving special instruction in mathematics with normally-achieving children. The participants were 73 fifth-grade children who receive special instruction and 70 children who do not receive any special instruction. In year four and five, the children's skills in mathematics and reading were assessed by national curriculum tests, and in their fifth year, self-efficacy in mathematics and reading were measured. Structural equation modeling showed that in domains where children do not receive special instruction in mathematics, self-efficacy is a mediating variable between earlier and later achievement in the same domain. Achievement in mathematics was not mediated by self-efficacy in mathematics for children who receive special instruction. For normal achieving children, earlier achievement in the language domain had an influence on later self-efficacy in the mathematics domain, and self-efficacy beliefs in different domains were correlated. Self-efficacy is mostly domain specific, but may play a different role in academic performance depending on whether children receive special instruction. The results of the present study provided some support of the Cross-Domain Influence Model for normal achieving children.

    Background To examine the effects of whole body vibration (WBV) exposure on muscle function in children with Cystic Fibrosis (CF). Non-randomised controlled cross-over trial. Methods The setting was home-based WBV exposure. The participants were children (8 - 15 years) with CF (n = 7). Intervention: participants served as their own controls for the first four weeks (usual care), then underwent four weeks of parentally-supervised home-based WBV exposure followed by four weeks washout (usual care). The WBV exposure consisted of 20 - 30 minutes of intermittent (1 min vibration:1 min rest) exposure on a Galileo platform (20 - 22Hz, 1 mm amplitude) 3 days/week. The primary outcome measures of absolute and relative lower body (leg extension (LE), leg press (LP)), upper body (chess press (CP)) strength and power, and power were measured at baseline, and weeks 4, 8 and 12. Secondary exploratory outcomes were cardiorespiratory fitness, pulmonary function and health-related quality of life. Results Six participants completed the training without adverse events. Muscle function changes following WBV exposure were not statistically significant. However, moderate-to-large relative effect sizes (ES) favouring WBV were evident for leg extension strength (ES = 0.66 (-0.50, 1.82)), LP relative strength (ES = 0.92 (-0.27, 2.11)), leg press peak power (ES = 0.78 (-0.50, 2.07)) and CMJ height (ES = 0.60 (-0.56 to 1.76)). Conclusions The results from this first controlled trial indicate that WBV may be a potentially effective exercise modality to safely increase leg strength and explosive power in children with CF. Potentially clinically relevant changes support continued investigation of the efficacy, mechanism and feasibility of this intervention in future large-scale studies. PMID:23671546

    Abstract Objective There has been recent interest in the use of cognitive enhancing drugs, such as cholinesterase inhibitors, as a possible treatment for executive functioning (EF) deficits in autism spectrum disorder (ASD). The goal of this study was to assess the tolerability, safety, and efficacy of donepezil on EF in a sample of children and adolescents with ASD. Method Thirty-four children and adolescents with ASD (age range 8–17 years; IQ >75) were enrolled in a 10-week, double-blind, placebo-controlled trial of donepezil (doses of 5 and 10 mg), followed by a 10-week open label trial for placebo nonresponders. Results The effect of donepezil treatment on EF was examined. Despite improvement on a number of EF measures, no statistically significant between-group differences were found (with gains observed for both the placebo and donepezil groups). Conclusions The results suggest that short-term treatment with donepezil may have limited impact on cognitive functioning in ASD. Future controlled trials may need to consider a longer treatment period to detect significant gains on EF measures. PMID:21309696

    Abstract Objective: The purpose of this study was to evaluate the long-term safety and efficacy of risperidone in treating irritability and related behaviors in children and adolescents with autistic disorders. Methods: In this 6 month (26 week) open-label extension (OLE) study, patients (5–17 years of age, who completed the previous fixed-dose, 6 week, double-blind [DB] phase) were flexibly dosed with risperidone based on body weight. The maximum allowed dose was 1.25 mg/day for those weighing 20 to <45 kg, and 1.75 mg/day for those weighing ≥45 kg. The study primarily assessed risperidone's safety; efficacy was assessed as a secondary end-point. Results: Fifty-six (71%) out of 79 enrolled patients completed the OLE; the most common discontinuations were for insufficient response (7 [9%]) or adverse events (AE) (5 [6%]). The most common (≥5% frequency in the total group) AEs were increased appetite (11% [n=9]); increased weight and vomiting (9% [n=7] each); sedation, pyrexia, and upper respiratory tract infection (8% [n=6] each); nasopharyngitis (6% [n=5]); and somnolence and fatigue (5% [n=4] each). Extrapyramidal AEs were reported in 6 (8%) patients. Increase in mean weight (11–15%) and body mass index (5–10%) occurred; one patient discontinued because of weight increase. One potentially prolactin-related AE (irregular menstruation) was reported. The risperidone high-dose group had the greatest mean improvement in sleep visual analog scale (24.6). All groups showed additional improvement in efficacy scale scores during the OLE. Conclusions: During this OLE, safety findings with risperidone treatment (maximum weight-based dose of 1.25 mg/day or 1.75 mg/day) were consistent with those observed in the DB phase, and with the current safety information for risperidone in autistic, psychiatric, and behavioral disorders. Patients experienced some additional improvement in irritability and related behaviors. Clinical Trials Registry: This phase-4

    Recent progress in medical knowledge has indicated that both clinical and biological markers will determine the response to different medical treatments: age, gender and genetics will determine the success of treatment. Genetic variability in this respect is fundamental and determines efficiency and safety of drugs, as well as susceptibility and illness' development. Fortunately, personalized medicine now offers individually tailored treatment strategies for each patient's needs. This is of outmost importance in oncology, since treatment is per se toxic and the commonly found low serum drug concentrations result in low treatment efficacy. Personalized medicine will allow a better approach to this, until now, a poorly managed disease. In this review we intent to raise awareness of personalized medicine and of clinical pharmacologic monitoring, with the aim to achieve adequate levels of efficacy and safety in the use of the cytotoxic drug 5-Fluorouracil (5-FU). Additionally, the importance of pharmacogenomics for the use of 5-FU is discussed. We designed this discussion towards medical practitioners challenged with treatment decisions every day, together with their patients.

    To evaluate the efficacy, safety, and tolerability of a classic 4:1 ketogenic diet using a formula-based powder in infants and children with refractory seizures who are reluctant to eat homemade foods. We conducted an open label trial and administered a ketogenic diet using formula-based power (Ketocal(®)). Twenty-seven infants and children aged between 12 months and 5 years were enrolled who had refractory seizures and were reluctant to eat homemade foods. Of 27 children, 5 were lost to follow-up and 22 were remained at the end of the study. After 4 months, the median frequency of seizures per week was reduced >50% in 68.2% of patients, while 9/22 children (40.9%) showed a 50-90% reduction in seizure frequency per week, and 6/22 children (27.3%) showed more than 90% reduction in seizure frequency per week. Over the study course, 6/22 (27%) children who continued to receive the diet developed constipation, one child developed gastroesophageal reflux, and one child developed hypercholesterolemia. None of these children discontinued the diet because of the complications. Thirteen children and their parents (59%) reported that the diet was palatable and tolerable enough. The ketogenic diet using a formula-based powder (Ketocal(®)) is effective, safe, and tolerable in infants and children with refractory seizures who are reluctant to eat homemade foods according to the rules of the ketogenic diet.

    Background While research on school children's health has mainly focused on risk factors and illness, few studies have examined aspects of health promotion. Thus, this study focuses on health promotional factors including general self-efficacy (GSE) and health-related quality of life (HRQOL). GSE refers to a global confidence in coping ability across a wide range of demanding situations, and is related to health. The purpose of this study was to examine associations between GSE and HRQOL, and associations between HRQOL and socio-demographic characteristics. Knowledge of these associations in healthy school children is currently lacking. Methods During 2006 and 2007, 279 school children in the seventh grade across eastern Norway completed a survey assessing their GSE and HRQOL. The children were from schools that had been randomly selected using cluster sampling. T-tests were computed to compare mean subscale values between HRQOL and socio-demographic variables. Single and multiple regression analyses were performed to explore associations among GSE, HRQOL and socio-demographic variables. Results Regression analyses showed a significant relationship between increasing degrees of GSE and increasing degrees of HRQOL. In analyses adjusted for socio-demographic variables, boys scored higher than girls on self-esteem. School children from single-parent families had lower scores on HRQOL than those from two-parent families, and children who had relocated within the last five years had lower scores on HRQOL than those who had not relocated. Conclusion The strong relationship between GSE and HRQOL indicates that GSE might be a resource for increasing the HRQOL for school children. PMID:19772673

    Two hundred and nine children receiving early childhood special education services for developmental disabilities or delays who also had behavioral, social, or attentional difficulties were included in a study of an intervention to increase school readiness, including early literacy skills. Results showed that the intervention had a significant positive effect on children's literacy skills from baseline to the end of summer before the start of kindergarten (d=.14). The intervention also had significant indirect effects on teacher ratings of children's literacy skills during the fall of their kindergarten year (β=.09). Additionally, when scores were compared to standard benchmarks, a greater percentage of the children who received the intervention moved from being at risk for reading difficulties to having low risk. Overall, this study demonstrates that a school readiness intervention delivered prior to the start of kindergarten may help increase children's early literacy skills.

    PubMed

    1986-10-01

    Dimethicone is a common additive to antacids, although its value in the treatment of reflux oesophagitis is unproven. Its efficacy was assessed by comparing the effect of a dimethicone-containing antacid gel (Asilone Gel) with a simple antacid gel in a double-blind trial in 45 patients with reflux oesophagitis. Thirty-eight patients completed the eight-week course of therapy. Antacid therapy alone resulted in a significant improvement of both symptoms and oesophagitis in gastro-oesophageal reflux. The inclusion of dimethicone in the antacid gel preparation did not confer any benefit in terms of symptomatic assessment but did confer a small advantage with regard to objective markers of oesophageal inflammation, suggesting that a dimethicone-containing antacid is of value in the treatment of symptomatic gastro-oesophageal reflux.

    In a recent publication we assessed the kinetics of intestinal colonization by microencapsulated probiotic bacteria in comparison with the same strains given in an uncoated form. It's well known, in fact, that microencapsulation of probiotics with specific materials is able to confer a significant resistance to gastric juice, thus protecting the cells during the gastric and duodenal transit and enhancing the probiotic efficacy of any supplementation. In any case, this was the first study reporting the fecal amounts of probiotics administered in a coated, protected form compared with traditional, uncoated ones. Here we discuss additional in vitro data of resistance of the same bacteria to gastric juice, human bile and pancreatic secretion and correlate them with the results of in vivo gut colonization.

    Purpose: To describe a technique of segmental radioembolization for the treatment of patients with unresectable hepatocellular carcinoma (HCC). Radiation segmentectomy was defined as radioembolization of two or fewer hepatic segments. We sought to (1) calculate dose when activity is delivered segmentally assuming uniform and nonuniform distribution and, (2) determine safety and efficacy of this novel technique. Methods and Materials: A total of 84 patients with HCC who were treated with {sup 90}Y radioembolization using a segmental approach were included in this analysis. The dose delivered to the segment was calculated assuming uniform and nonuniform microsphere distribution within the treatment volume. To calculate dose assuming nonuniform distribution, a tumor hypervascularity ratio was assigned. Posttreatment response (using size and necrosis guidelines), toxicity, time to progression, and survival were determined. Results: The median treatment volume was 110 cm{sup 3}. The median radiation-naive liver volume was 1403 cm{sup 3}. The median dose delivered to the segment(s) assuming uniform distribution was 521 Gy. Taking into account tumor hypervascularity (nonuniform distribution), the median dose delivered to the tumor and normal infused hepatic volume was 1214 Gy and 210 Gy, respectively. Response by size and necrosis guidelines was seen in 59% and 81% of patients. Grade 3/4 biochemical toxicities were observed in 8 patients (9%). Median time to progression was 13.6 months (95% confidence interval, 9.3-18.7 months); median survival was 26.9 months (95% confidence interval, 20.5-30.2 months). Conclusions: Radiation segmentectomy is a safe and efficacious method of selectively delivering high dose to the tumor with minimal exposure of normal parenchyma.

    National studies indicate that an increasing proportion of children are receiving needed oral health care. However, this increase is not uniform throughout all populations of youngsters. Overall national study findings regarding the use of dental services mask the fact that, a significant subset of low-income, minority, medically and developmentally compromised and socially vulnerable children continue to lack access to care and suffer significant and consequential dental and oral disease. In addition, these same children will face continued difficulties in securing needed care as they reach their early adult years.

    Accumulating evidence indicates that immune dysfunction is associated with autism disorders in a significant subset of children. Previous reports have shown abnormal immunoglobulin (Ig) levels, including an increased presence of autoreactive antibodies in the circulation of individuals with autism. As IgG is the predominant antibody isotype in circulation, we expected that an altered immune response could result in an abnormal IgG subclass profile in children with autism. We examined circulating plasma levels of IgG1, IgG2, IgG3, and IgG4 in 241 children from the CHARGE (Childhood Autism Risks from Genetics and the Environment) study, a large epidemiologic case-control investigation, including 114 children who meet full criteria for autism disorder (AU), 96 typically developing control children (TD) from a randomly selected sample of the general population, and 31 children with developmental delays (DD). We report significantly increased levels of the IgG4 subclass in children with AU compared with TD control children (p=0.016) and compared with DD controls (p=0.041). These results may suggest an underlying immunological abnormality in AU subjects resulting in elevated IgG4 production. Further investigation is necessary to elucidate the relationship between immunological findings and behavioral impairments in autism. PMID:19136055

    2015-01-01

    The current study is a randomized clinical trial evaluating the efficacy of Focused Playtime Intervention (FPI) in a sample of 70 children with Autism Spectrum Disorder. This parent-mediated intervention has previously been shown to significantly increase responsive parental communication (Siller et al. in J Autism Dev Disord 43:540–555, 2013a). The current analyses focus on children’s attachment related outcomes. Results revealed that children who were randomly assigned to FPI showed bigger increases in attachment-related behaviors, compared to children assigned to the control condition. Significant treatment effects of FPI were found for both an observational measure of attachment-related behaviors elicited during a brief separation-reunion episode and a questionnaire measure evaluating parental perceptions of child attachment. The theoretical and clinical implications of these findings are discussed. PMID:24488157

    There have been major advances in the treatment and understanding of attention-deficit hyperactivity disorder (ADHD) in the last decade. Among these are the availability of newer stimulant formulations, an appreciation of the combined effects of medication and behavioural therapies, and a better understanding of the neurobiology of the disorder in children (aged 6-12 years), adolescents and adults. This article focuses on the evaluation of the efficacy and safety profiles of medications used for the management of ADHD. In assessing the various medical treatments for ADHD, certain issues and analyses have become important to address. The diagnosis, characterization and quantification of ADHD symptoms are crucial to assessing treatment effectiveness. A standardized setting for measuring the severity of ADHD symptoms is the laboratory school protocol, which simulates a school environment with tightly controlled timing of measurements. This method has been adapted successfully to the adult workplace environment to help with the evaluation of adult ADHD symptoms. Statistical analyses, such as effect size and number needed to treat, may aid in the comparison and interpretation of ADHD study results. Although an objective approach to evaluating the efficacy and safety profiles of the available medications provides necessary details about the medical options, typical clinical decisions are often based on trial and error and may be individualized based on a patient's daily routine, comorbidities and risk factors. Stimulants remain the US FDA-approved medical treatment of choice for patients with ADHD and are associated with an exceptional response rate. Findings of the Multimodal Treatment of Children With ADHD study suggest that the combination of behavioural and medical therapy may benefit most patients. Nonstimulant agents, such as atomoxetine (FDA-approved), and several non-approved agents, bupropion, guanfacine and clonidine, may offer necessary alternatives to the

    Cerebral Palsy (CP) refers to a heterogeneous group of permanent but non-progressive movement disorders caused by injury to the developing fetal or infant brain (Bax et al., 2005). Because of its serious long-term consequences, effective interventions that can help improve motor function, independence, and quality of life are critically needed. Our ongoing longitudinal clinical trial to treat children with CP is specifically designed to meet this challenge. To maximize the potential for functional improvement, all children in this trial received autologous cord blood transfusions (with order randomized with a placebo administration over 2 years) in conjunction with more standard physical and occupational therapies. As a part of this trial, magnetic resonance imaging (MRI) is used to improve our understanding of how these interventions affect brain development, and to develop biomarkers of treatment efficacy. In this report, diffusion tensor imaging (DTI) and subsequent brain connectome analyses were performed in a subset of children enrolled in the clinical trial (n = 17), who all exhibited positive but varying degrees of functional improvement over the first 2-year period of the study. Strong correlations between increases in white matter (WM) connectivity and functional improvement were demonstrated; however no significant relationships between either of these factors with the age of the child at time of enrollment were identified. Thus, our data indicate that increases in brain connectivity reflect improved functional abilities in children with CP. In future work, this potential biomarker can be used to help differentiate the underlying mechanisms of functional improvement, as well as to identify treatments that can best facilitate functional improvement upon un-blinding of the timing of autologous cord blood transfusions at the completion of this study.

    Cerebral Palsy (CP) refers to a heterogeneous group of permanent but non-progressive movement disorders caused by injury to the developing fetal or infant brain (Bax et al., 2005). Because of its serious long-term consequences, effective interventions that can help improve motor function, independence, and quality of life are critically needed. Our ongoing longitudinal clinical trial to treat children with CP is specifically designed to meet this challenge. To maximize the potential for functional improvement, all children in this trial received autologous cord blood transfusions (with order randomized with a placebo administration over 2 years) in conjunction with more standard physical and occupational therapies. As a part of this trial, magnetic resonance imaging (MRI) is used to improve our understanding of how these interventions affect brain development, and to develop biomarkers of treatment efficacy. In this report, diffusion tensor imaging (DTI) and subsequent brain connectome analyses were performed in a subset of children enrolled in the clinical trial (n = 17), who all exhibited positive but varying degrees of functional improvement over the first 2-year period of the study. Strong correlations between increases in white matter (WM) connectivity and functional improvement were demonstrated; however no significant relationships between either of these factors with the age of the child at time of enrollment were identified. Thus, our data indicate that increases in brain connectivity reflect improved functional abilities in children with CP. In future work, this potential biomarker can be used to help differentiate the underlying mechanisms of functional improvement, as well as to identify treatments that can best facilitate functional improvement upon un-blinding of the timing of autologous cord blood transfusions at the completion of this study.

    Reading is a multifaceted skillset that has the potential to profoundly impact a child’s academic performance and achievement. Mastery of reading skills is often an area of difficulty for children during their academic journey, particularly for children with Attention Deficit/Hyperactivity Disorder (ADHD), Specific Learning Disorder with Impairment in Reading (SLD-R), or children with a comorbid diagnosis of both ADHD and SLD-R. ADHD is characterized by executive functioning and impulse control deficits, as well as inattention and impulsivity. Among the academic struggles experienced by children with ADHD are challenges with word reading, decoding, or reading comprehension. Similarly, children with SLD-R frequently encounter difficulties in the development of appropriate reading skills. SLD-R incorporates dysfunctions in basic visual and auditory processes that result in difficulties with decoding and spelling words. There have been limited empirical studies investigating the efficacy of interventions to improve the reading ability of children with both ADHD and SLD-R. Research studies that have focused on reading interventions for children from this population have predominantly included the use of medication treatments with stimulants (e.g., methylphenidate) and non-stimulants (e.g., atomoxetine). This review paper will present and integrate findings from empirical studies on successful medication treatments for children with comorbid ADHD and SLD-R. Furthermore, this paper will extend findings from empirically successful medication treatments to provide directions for future research. PMID:27458398

    Recent studies have shown that obesity is associated with an increased risk of fracture in both adults and children. It has been suggested that, despite greater bone size, obese individuals may have reduced true volumetric density; however this is difficult to assess using two dimensional techniques such as DXA. We evaluated the relationship between fat mass, and bone size and density, in a population cohort of children in whom DXA and pQCT measurements had been acquired. We recruited 530 children at 6 years old from the Southampton Women's Survey. The children underwent measurement of bone mass at the whole body, lumbar spine and hip, together with body composition, by DXA (Hologic Discovery, Hologic Inc., Bedford, MA, USA). In addition 132 of these children underwent pQCT measurements at the tibia (Stratec XCT2000, Stratec Biomedical Systems, Birkenfeld, Germany). Significant positive associations were observed between total fat mass and both bone area (BA) and bone mineral content (BMC) at the whole body minus head, lumbar spine and hip sites (all p<0.0001). When true volumetric density was assessed using pQCT data from the tibia, fat mass (adjusted for lean mass) was negatively associated with both trabecular and cortical density (β=-14.6 mg/mm(3) per sd, p=0.003; β=-7.7 mg/mm(3) per sd, p=0.02 respectively). These results suggest that fat mass is negatively associated with volumetric bone density at 6 years old, independent of lean mass, despite positive associations with bone size.

    Health care services for children with autism spectrum disorder are often expensive and frequently not covered under private health insurance. The 2008 Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act was viewed as a possible means of improving access by eliminating differences between behavioral health and medical/surgical benefits. We examined whether the legislation was associated with increased use of and spending on mental health care and functional services for children with autism spectrum disorder compared to the period prior to implementation of the law. We used nationwide health insurance commercial group claims data to examine trends in service use and spending among children with autism spectrum disorder before and after implementation of the law. For such children, implementation was associated with increased use of both mental health and non-mental health services. These increases in use were not associated with higher out-of-pocket spending, which suggests that the law improved financial protection for families.

    Discovering whether children prefer reinforcement via a contingency or independent of their behavior is important considering the ubiquity of these programmed schedules of reinforcement. The current study evaluated the efficacy of and preference for social interaction within differential reinforcement of alternative behavior (DRA) and noncontingent reinforcement (NCR) schedules with typically developing children. Results showed that 7 of the 8 children preferred the DRA schedule; 1 child was indifferent. We also demonstrated a high degree of procedural fidelity, which suggested that preference is influenced by the presence of a contingency under which reinforcement can be obtained. These findings are discussed in terms of (a) the selection of reinforcement schedules in practice, (b) variables that influence children's preferences for contexts, and (c) the selection of experimental control procedures when evaluating the effects of reinforcement.

    Introduction  Otitis media with effusion (OME) is a leading cause of hearing impairment in children. Therefore, early and proper management is essential. Objectives  The objective of this research is to assess the efficacy of intratympanic (IT) steroids injection for management of otitis media with effusion (OME). Methods  This study involved 42 children (84 ears) with bilateral OME. We used tympanometry to confirm the childreńs middle ear effusion and pure tone audiometry to determine hearing threshold. We performed myringotomy and inserted ventilation tubes (VTs) bilaterally, followed by a steroid injection of 0.4–0.6 mL methylprednisolone (40 mg/mL) into one randomly selected middle ear. This procedure was followed by once-weekly administration of steroids (0.5 mL methylprednisolone at a concentration of 40 mg/mL) into the middle ear for three consecutive weeks. Results  We found recurrent OME after VT alone in nine (21.4%) ears; whereas, after VT combined with steroid administration, we found two (4.76%), with statistically significant difference. We noted tympanosclerosis postoperatively in six (12.9%) ears and in one of the injected ears (2.3%) (p = 0.0484). Otorrhea occurred in eight (19%) ears with VT alone and in three (7.1%) injected ears, with non-significant difference. The duration between VT insertion and its extrusion was 6.6 = 1.1 months for ears with VT alone and 6.95 =1.12 months in injected ears (p = 0.1541 NS). Conclusion  IT Steroids injection for treatment of OME is a safe and simple intervention with lower incidence of symptoms recurrence and postoperative complications. Thus, its use in management of OME is recommended. PMID:27413407

    Objectives Increased air pollutant concentrations have been linked to several asthma-related outcomes in children, including respiratory symptoms, medication use, and hospital visits. However, few studies have examined effects of ultrafine particles in a pediatric population. Our primary objective was to examine the effects of ambient concentrations of ultrafine particles on asthma exacerbation among urban children and determine whether consistent treatment with inhaled corticosteroids could attenuate these effects. We also explored the relationship between asthma exacerbation and ambient concentrations of accumulation mode particles, fine particles (≤ 2.5 micrograms [μm]; PM2.5), carbon monoxide, sulfur dioxide, and ozone. We hypothesized that increased 1 to 7 day concentrations of ultrafine particles and other pollutants would be associated with increases in the relative odds of an asthma exacerbation, but that this increase in risk would be attenuated among children receiving school-based corticosteroid therapy. Methods We conducted a pilot study using data from 3–10 year-old children participating in the School-Based Asthma Therapy trial. Using a time-stratified case-crossover design and conditional logistic regression, we estimated the relative odds of a pediatric asthma visit treated with prednisone (n=96 visits among 74 children) associated with increased pollutant concentrations in the previous 7 days. We re-ran these analyses separately for children receiving medications through the school-based intervention and children in a usual care control group. Results Interquartile range increases in ultrafine particles and carbon monoxide concentrations in the previous 7 days were associated with increases in the relative odds of a pediatric asthma visit, with the largest increases observed for 4-day mean ultrafine particles (interquartile range=2088 p/cm3; OR=1.27; 95% CI=0.90–1.79) and 7-day mean carbon monoxide (interquartile range=0.17 ppm; OR=1.63; 95

    Bilingual children regularly face communicative challenges when speakers switch languages. To cope with such challenges, children may attempt to discern a speaker's communicative intent, thereby heightening their sensitivity to nonverbal communicative cues. Two studies examined whether such communication breakdowns increase sensitivity to nonverbal cues. English-speaking monolingual (n = 64) and bilingual (n = 54) 3- to 4-year-olds heard instructions in either English only or English mixed with a foreign language. Later, children played a hiding game that relied on nonverbal cues. Hearing a foreign language switch improved both monolingual and bilingual children's use of these cues. Moreover, bilinguals with more prior code-switching exposure outperformed those with less prior code-switching exposure. Children's short-term strategies to repair communication breakdowns may evolve into a more generalizable set of skills.

    Electroporation is used in tissue for gene therapy, drug therapy and minimally invasive tissue ablation. The electrical field that develops during the application of the high voltage pulses needs to be precisely controlled. In the region to be treated, it is desirable to generate a homogeneous electric field magnitude between two specific thresholds whereas in other regions the field magnitude should be as low as possible. In the case of irregularly shaped tissue structures, such as bulky tumors, electric field homogeneity is almost impossible to be achieved with current electrode arrangements. We propose the use of conductive gels, matched to the conductivity of the tissues, to fill dead spaces between plate electrodes gripping the tissue so that the electric field distribution becomes less heterogeneous. Here it is shown that this technique indeed improves the antitumor efficacy of electrochemotherapy in sarcomas implanted in mice. Furthermore, we analyze, through finite element method simulations, how relevant the conductivity mismatches are. We found that conductivity mismatching errors are surprisingly well tolerated by the technique. Gels with conductivities ranging from 5 mS cm-1 to 10 mS cm-1 will be a proper solution for most cases.

    Most studies of attention-deficit hyperactivity disorder (ADHD) youth have obtained data from the perspective of either children or parents, but not both simultaneously. The purpose of this study was to examine child and parent perspectives on parenting in a large community-based sample of children with and without ADHD. We identified children in grades 4-6 and their parents through surveys administered to a random sample of public schools. We used multivariable logistic regression to determine independent associations between child and parent characteristics and the presence of ADHD while controlling for covariates and clustering by school. Sufficient data were achieved for 2,509 child/parent dyads. Ten percent of youths (n = 240) had been diagnosed with ADHD. Compared with those without ADHD, those with ADHD were more commonly male (67.9 vs. 48.0 %, p < .001) and age 12 or over (16.3 vs. 10.3 %). After adjusting for covariates and clustering, compared to children without ADHD, children with ADHD were significantly more likely to report lower self-regulation (OR = 0.68, 95 % CI = 0.53, 0.88) and higher levels of rebelliousness (OR = 2.00, 95 % CI = 1.52, 2.69). Compared with parents whose children did not have ADHD, parents of children with ADHD rated their overall parental efficacy substantially lower (OR = 0.23, 95 % CI = 0.15, 0.33). However, child assessment of parenting style was similar by ADHD. Despite the internal challenges community-based youth with ADHD face, many parents of ADHD youth exhibit valuable parental skills from the perspective of their children. Feedback of this information to parents may improve parental self-efficacy, which is known to be positively associated with improved ADHD outcomes.

    Background Successful eradication of Helicobacter pylori is becoming more difficult, mainly due to emerging antibiotic resistance. Treatment regimens containing bismuth have increased efficacy, but the mechanism is unknown. H. pylori is a neutralophile adapted to survive the acidic gastric environment via acid acclimation, but demonstrates more robust growth at neutral pH. Many antibiotics used to treat H. pylori rely on bacterial growth. Aim To investigate the mechanism of increased efficacy of bismuth-containing H. pylori treatment regimens. Methods RNAseq and qPCR, urease activity in permeabilized and intact bacteria, internal pH, and membrane potential were measured with and without colloidal bismuth subcitrate (CBS). Bacterial survival was assessed with CBS and/or ampicillin. Results Genes involved with metabolism and growth were upregulated in the presence of CBS at acidic pH. Urease activity of permeabilized H. pylori at pH 7.4 and 4.5 decreased in the presence of CBS, but intact urease activity only decreased at acidic pH. The fall in cytoplasmic pH with external acidification was diminished by CBS. The increase in membrane potential in response to urea addition at acidic medium pH was unaffected by CBS. The impact of CBS and ampicillin on H. pylori survival was greater than either agent alone. Conclusions Bismuth is not acting directly on urease or the urea channel. CBS impedes proton entry into the bacteria, leading to a decrease in the expected fall in cytoplasmic pH. With cytoplasmic pH remaining within range for increased metabolic activity of a neutralophile, the efficacy of growth dependent antibiotics is augmented. PMID:26238858

    Children's food preferences play a major role in their food choices and consumption. The objective of the present study was to examine if repeated tastings of selected vegetables in a school setting increased children's liking of these items. A total of 360 fourth- and fifth-grade students attending four low-income, public elementary schools in southeastern Louisiana volunteered to participate. During the spring of 2008, children were offered a taste of carrots, peas, tomatoes, and bell peppers once a week for 10 weeks. At each tasting session children recorded whether they swallowed each of the vegetables, spit it into the napkin, or did not put it in their mouth and indicated their liking for each vegetable using a Likert-type response scale. Approximately one-half of the children tasted eight of ten times during the program (46.5% for those who began disliking and 68.5% for those who began liking the vegetables). Proc Glimmix analyses indicated that for children who began the program disliking the vegetables, repeated tasting improved liking scores for carrots, peas, and tomatoes; liking for bell peppers did not change. The number of children who reported liking or liking a lot for previously disliked vegetables was greater after eight or nine taste exposures. Repeated tasting of less-liked vegetables by children in a cafeteria-based setting is a strategy to promote liking of these items and is effective in approximately half of the participants.

    To evaluate the efficacy of specific sublingual immunotherapy (SLIT), we enrolled 15 children with asthma and rhinitis (7 girls, 8 boys, mean +/- SD age of 11.7 +/- 3.3) allergic to house dust mite (HDM) into a double-blind, placebo-controlled study. After a run-in period, patients were randomized to receive either placebo (n = 7) or SLIT (n = 8) with a standardized Dermatophagoides pteronyssinus (D. pteronyssinus) + Dermatophagoides farinea (D. farinea) 50/50 extract. They received increasing doses up to 100 index units of reactivity (IR) every day for 4 weeks, then 100 IR/day for another 4 weeks, followed by maintenance therapy consisting of 20 drops 2 times a week for 4 months. Efficacy was assessed at the end of 6 months of therapy according to symptom and medication scores, serum total IgE levels, results of lung function tests, methacholine provocation tests, and skin prick tests. Daily means for the asthma score and use of inhaled beta-2-mimetics decreased significantly in the SLIT group (P = 0.05, P = 0.028, respectively), whereas no such difference was observed in the placebo group. At the end of follow-up, mean daily doses of intranasal steroids needed for control of rhinitis symptoms decreased significantly in the SLIT group (P = 0.04). Baseline skin sensitivity to D. pteronyssinus and D. farinea was not significantly different between in the two groups, whereas end-point wheal diameter obtained with D. pteronyssinus extract was significantly less in the SLIT vs. the placebo group (P = 0.026). At the end of 6 months, peak expiratory flow (PEF) values in the placebo group was significantly lower than in the SLIT group (P = 0.049). Throughout the treatment period, the SLIT group was found to have less asthma exacerbations than the placebo group (P = 0.007). The provocation concentration causing a 20% drop in forced expired volume in 1 sec did not change throughout the treatment period in either groups. None of the patients reported local or systemic side

    Suboptimal vitamin D (vitD) status (<32 ng/ml) is ubiquitous among African American children with type SS sickle cell disease (SCD-SS). The vitD supplemental dose to normalize vitD status is unknown. Five to 20-year-old African-American children with (n=21) and without (n=23) SCD-SS were randomized to vitD3 supplementation (4,000 or 7,000 IU/day) and evaluated at 6- and 12-weeks for changes in vitD and SCD status. A dose was considered unsafe if serum calcium was elevated associated with elevated serum 25 hydroxyvitamin D (25(OH)D)). At baseline 95% of subjects with SCD-SS and 87% of healthy controls had suboptimal vitD status (mean ± SD, 19.2 ± 7.2 and 22.3 ± 9.3 ng/ml, respectively). After 12-weeks supplementation, both D3 doses were safe and well tolerated. Neither group achieved the a priori efficacy criterion of 25(OH)D ≥ 32 ng/ml in >80% of subjects (45% in SCD-SS and 63% in controls). However for both subjects with SCD-SS and healthy subjects by 12-weeks, deficient (< 20 ng/ml) vitD status was eliminated only in those receiving 7,000 IU/d. For subjects with SCD-SS, by 12-weeks there was a significant (all P<0.05) increase in fetal hemoglobin, decrease in HS-CRP, and reduction in the percentage of subjects with a high platelet count.

    Chronic exposure to urban traffic pollution is documented to promote atherosclerosis in adults but little is known about its potential effects in children. Our study examined the association of long-term exposure to traffic with carotid intima-media thickness (cIMT) in 287 healthy children. Residential proximity and distance-weighted traffic density (DWTD) were used as proximity markers for traffic-related air pollution exposure. The multivariable analyses revealed that children residing <100 meters from the nearest heavily trafficked road had cIMT mean and maximum measurements that were increased by 15% and 11% compared to those living ≥ 200 meters away (P = 0.0001). Similar increases in cIMT were identified for children in the highest versus lowest DWTD tertile. Children who resided 100–199 meters from traffic or in the middle DWTD tertile also exhibited increased cIMT but these differences were not statistically significant. No statistically significant differences were identified between residential distance to traffic or DWTD and systemic inflammation indicators (CRP, IL-6). The study results suggest that exposure to urban traffic promotes arterial remodeling in children. This finding is important since even small increases in cIMT over time can potentially lead to earlier progression to atherosclerosis. It is also important because traffic-related pollution is potentially modifiable. PMID:25685160

    To improve the efficacy of the in-house validation of GMO detection methods (DNA isolation and real-time PCR, polymerase chain reaction), a study was performed to gain insight in the contribution of the different steps of the GMO detection method to the repeatability and in-house reproducibility. In the present study, 19 methods for (GM) soy, maize canola and potato were validated in-house of which 14 on the basis of an 8-day validation scheme using eight different samples and five on the basis of a more concise validation protocol. In this way, data was obtained with respect to the detection limit, accuracy and precision. Also, decision limits were calculated for declaring non-conformance (>0.9%) with 95% reliability. In order to estimate the contribution of the different steps in the GMO analysis to the total variation variance components were estimated using REML (residual maximum likelihood method). From these components, relative standard deviations for repeatability and reproducibility (RSD(r) and RSD(R)) were calculated. The results showed that not only the PCR reaction but also the factors 'DNA isolation' and 'PCR day' are important factors for the total variance and should therefore be included in the in-house validation. It is proposed to use a statistical model to estimate these factors from a large dataset of initial validations so that for similar GMO methods in the future, only the PCR step needs to be validated. The resulting data are discussed in the light of agreed European criteria for qualified GMO detection methods.

    Selective attention and efficacy are important components of scholastic performance in school children. While attempts are being made to introduce new methods to improve academic performance either as part of curricular or extracurricular activities in schools, the success rates are minimal. Hence, this study assessed the effect of yoga-based intervention on psychomotor performance and self-efficacy in school children. Two hundred ten school children with ages ranging from 11 to 16 years (mean age ± SD; 13.7 ± 0.8 years) satisfying the inclusion and exclusion criteria were recruited for the 10-day yogä program. An equal number of age-matched participants (n = 210; mean ± SD; 13.1 ± 0.8 years) were selected for the control group. Participants were assessed for attention and performance at the beginning and end of 10 days using trail making task (TMT) A and B, and self-efficacy questionnaire. The yoga group showed higher self-efficacy and improved performance after 10 days of yoga intervention. The performance in TMT-A and -B of the yoga group showed a significantly higher number of attempts with a reduction in time taken to complete the task and a number of wrong attempts compared with control group. Results suggest that yoga practice enhances self-efficacy and processing speed with fine motor coordination, visual–motor integration, visual perception, planning ability, and cognitive performance.

    Correlational studies have revealed a positive relationship between parent verbal responsiveness and language outcomes in children with autism. We investigated whether parents of young children on the autism spectrum could learn and implement the specific categories of verbal responsiveness that have been suggested to facilitate language development. Parents were taught to increase their verbal responsiveness in the context of a short-term language intervention that included group parent education sessions, as well as individual and small-group coaching sessions of parent-child play interactions. Parents in the treatment group increased their use of comments that: described their child's focus of attention; interpreted or expanded child communication acts; and prompted child communication. Preliminary treatment effects were also noted in children's prompted and spontaneous communication. These results support the use of parent-mediated interventions targeting verbal responsiveness to facilitate language development and communication in young children with autism.

    Two groups of children with cerebral paralysis received combined therapy. Treatment of one of the groups included a course of magnetotherapy (AMO-ATOS unit, 10 Hz) according to the suboccipital-lumbar method, the other group was control (no magnetotherapy). The study of cliniconeurophysiological indices showed significantly higher efficacy of the therapeutic complex with a course of magnetotherapy. The highest beneficial effect was observed on bioelectrogenesis of the brain, rheoencephalographic parameters and clinical manifestation of muscular spasticity.

    Sedation of children for electroencephalography (EEG) recordings is often required. Chloral hydrate (CH) requires medical clearance and continuous monitoring. To try to reduce personnel and time resources associated with CH administration, a new sedation policy was formulated. This study included all children who underwent an EEG during a consecutive 3-month period following the implementation of the new sedation policy, which consists of the sequential administration of melatonin, hydroxyzine (if needed), and CH (if needed). The comparator group included all children with a recorded EEG during a consecutive 3-month period when the sedation policy consisted of the sole administration of CH. A total of 803 children with a mean age of 7.9 years (SD = 5.1, range = 0.5-17.7 years) were included. Sleep EEG recordings were obtained in 364 of 385 children (94.6%) using the old sedation policy and in 409 of 418 children (97.9%) using the new one. With the new sedation policy, the percentage of children requiring CH dropped from 37.1% to 6.7% (P < .001). Time to sleep onset and duration of sleep were not significantly different between the 2 policies. The new sedation policy was very well tolerated. The new sedation policy is very safe, is highly efficacious in obtaining sleep EEG recordings, and will result in substantial saving of time and personnel resources.

During intervention, percentile schedules were used to calculate individual prize-draw criteria. The final week was a return to baseline. Four subjects increased step counts as a result of the intervention. A bout analysis of interresponse times revealed that subjects increased overall step counts by increasing daily minutes active and within-bout response rates and decreasing pauses between bouts of activity. Strategies to improve effectiveness are suggested, such as modification of reinforcement probability and amount and identification of the function of periods of inactivity.

    This study evaluated a staff-training and feedback program to increase (a) staff use of naturalistic language training techniques, and (b) child production of spontaneous vocal requests in a school setting for young children with autism. Training was conducted in integrated preschool centers and in an art group. The results revealed that the training and feedback procedure was successful in increasing staff use of naturalistic language training techniques. Further, these increased strategies were associated with corresponding increases in spontaneous vocal requests for all children during embedded training and ongoing feedback conditions. In addition, probes collected by an unobtrusive observer revealed durability of child requesting when staff feedback was discontinued. Social validity measures from front-line staff regarding the intervention revealed positive ratings. The results are discussed in relation to the continued search for effective service-delivery systems to improve communication for children with autism in the public school setting. PMID:27999635

    While there is consensus that bipolar disorder exists in children and adolescents, its diagnostic criteria are debated. Excessive sexual behavior has been reported in youth who may have juvenile bipolar disorder (JBD), and has been termed "hypersexuality." Although there is no universal definition of this term, this observation has led to a hypothesis that increased sexual behavior characterizes the bipolar syndrome in children and adolescents, and differentiates it from attention deficit hyperactivity disorder. Although this hypothesis is plausible, evidence for it is incomplete, because testing it definitively would require both establishing a standard definition of hypersexuality in children and adolescents, and also reaching consensus about the other nonsexual criteria for pediatric bipolar disorder. In addition, studies to test it would need to control factors other than JBD that are known to increase sexual behavior in children and adolescents. These include sexual abuse and related posttraumatic stress disorder, excessive exposure to sexual stimuli, psychiatric illness in general, and social variables such as family chaos and social stress. Some of these factors might increase sexual behavior in youth with bipolar disorder through psychodynamic mechanisms rather than as a result of the illness itself. Therefore, further research is needed to determine whether increased sexual behavior can serve as a diagnostically valuable criterion for bipolar disorder in children and adolescents, and whether it differentiates the disorder from other conditions known to be associated with increased sexual behavior in youth.

    Evidence exists for deficits in error monitoring in autism. These deficits may be particularly important because they may contribute to excessive perseveration and repetitive behavior in autism. We examined the neural correlates of error monitoring using fMRI in 8–12-year-old children with high-functioning autism (HFA, n=11) and typically developing children (TD, n=15) during performance of a Go/No-Go task by comparing the neural correlates of commission errors versus correct response inhibition trials. Compared to TD children, children with HFA showed increased BOLD fMRI signal in the anterior medial prefrontal cortex (amPFC) and the left superior temporal gyrus (STempG) during commission error (versus correct inhibition) trials. A follow-up region-of-interest analysis also showed increased BOLD signal in the right insula in HFA compared to TD controls. Our findings of increased amPFC and STempG activity in HFA, together with the increased activity in the insula, suggest a greater attention towards the internally-driven emotional state associated with making an error in children with HFA. Since error monitoring occurs across different cognitive tasks throughout daily life, an increased emotional reaction to errors may have important consequences for early learning processes.

    Increasing detection and capture probabilities of rare or elusive herpetofauna of conservation concern is important to inform the scientific basis for their management and recovery. The Giant Gartersnake (Thamnophis gigas) is an example of a secretive, wary, and generally difficult-to-sample species about which little is known regarding its patterns of occurrence and demography. We therefore evaluated modifications to existing traps to increase the detection and capture probabilities of the Giant Gartersnake to improve the precision with which occurrence, abundance, survival, and other demographic parameters are estimated. We found that adding a one-way valve constructed of cable ties to the small funnel opening of traps and adding hardware cloth extensions to the wide end of funnels increased capture rates of the Giant Gartersnake by 5.55 times (95% credible interval = 2.45–10.51) relative to unmodified traps. The effectiveness of these modifications was insensitive to the aquatic habitat type in which they were deployed. The snout-vent length of the smallest and largest captured snakes did not vary among trap modifications. These trap modifications are expected to increase detection and capture probabilities of the Giant Gartersnake, and show promise for increasing the precision with which demographic parameters can be estimated for this species. We anticipate that the trap modifications found effective in this study will be applicable to a variety of aquatic and semi-aquatic reptiles and amphibians and improve conservation efforts for these species.

    Studies on the adoption and maintenance of group exercise behavior are scarce. The objective of this study is to test two self-efficacy based interventions to increase barrier self-efficacy and group exercise behavior. In total 122 participants (Mage 42.02 yr.; SD 12.29; 67% females) were recruited and randomly assigned to one control and two experimental groups. The control group was limited to participate in one virtual group exercise program only (group 1). The first experimental group was able to self-set their activities and participate in multiple group exercise programs (group 2). The second experimental group received an additional monthly coaching protocol to manage self-set goals (group 3). A validated scale for barrier self-efficacy was used, group exercise sessions were measured and drop-out rates were registered. An ANOVA indicated that mean amount of sessions of group 1 and 3, and 2 and 3 differed significantly (p < 0.05) in 12 weeks. Descriptive statistics demonstrate mean group exercise sessions over the total of 12 weeks of 2.74 (SD 4.65) in the control group; 4.75 (SD 6.08) in the first experimental group, and 12.25 (SD 9.07) for the second experimental group. Regression analysis indicated that self-efficacy at 8-weeks explained the highest variance in overall group exercise sessions (R2 = 0.18; p < 0.05). Overall drop-out rates were 88% in group 1, 78% in group 2 and 48% in group 3. The results showed that group exercise behavior can significantly be improved by a coaching protocol on self-set goals. Future research should address the effectiveness of self-set activities and self-set goals for a longer period of time and in other types of exercise programs. Key points Approximately 144 million individuals exercise in fitness clubs worldwide. About 50% participate in at least one group exercise program and 23% participate only in group exercise classes with instructor.

    Evidence suggests that activating certain components of the immune system may increase regeneration and plasticity in the injured central nervous system. Investigating the effect of lipopolysaccharide (LPS), a potent endotoxin and immune activator, on neuronal plasticity in rat models of spinal cord injury, we discovered that systemic administration of LPS can increase the number of descending motor axons that transport neuronal tracers anterogradely to the spinal cord. This effect of LPS was not observed across all motor tracts traced in two different experiments, but was significant for two different tracers administered to corticospinal tract neurons. Densitometry measurement of traced corticospinal axons within the cervical gray matter revealed that normalization to the number of traced axons is crucial to avoid false-positive reports of increased plasticity following LPS injection. These findings indicate that assessments of neuronal growth based on neuronal tracing techniques should be normalized when inflammation or immune activation is an experimental variable.

    Herpes zoster is rare in healthy children, but immunocompromised persons have an increased risk of herpes zoster and severe diseases. Considering the very limited information on herpes zoster in children with cancer, we performed a nationwide population-based cohort study to estimate the incidence of herpes zoster in children with cancer and to explore the association between the 2 diseases.Data were obtained from the National Health Research Institutes Database in Taiwan. A total of 4432 children with newly diagnosed cancer between 2000 and 2007 were identified as the cancer cohort, and 17,653 children without cancer frequency-matched by sex and age at entry were considered the noncancer cohort. The association between herpes zoster and childhood cancer was determined.Children with cancer had a higher risk of herpes zoster. The incidence rate of herpes zoster was higher in the cancer cohort than in the noncancer cohort (20.7 vs 2.4 per 10,000 person-years; IRR = 8.6; 95% CI = 4.8-15.6). The cumulative incidence was significantly higher in the cancer cohort (P < 0.0001). Leukemia, lymphoma, and solid tumor were all associated with the increased risk, and leukemia had the highest magnitude of strength of association.This nationwide population-based cohort study demonstrated that children with cancer were associated with an increased risk of herpes zoster. In addition to early antiviral treatment, vaccination with heat-treated zoster vaccine or adjuvanted subunit vaccine could be an appropriate policy to decrease the incidence in children with cancer.

    The Fresh Kids programme utilized the Health Promoting Schools (HPSs) framework to design a whole-of-school, multifaceted intervention targeting specific behaviours to promote healthy eating and reduce the risk factors associated with childhood obesity. The aim of the programme was to evaluate the effectiveness of the HPS framework to increase fruit and water consumption among primary school-aged children over a 2-year period. The study design was an interrupted time series. Four primary schools in the inner west of Melbourne, Australia, participated in the programme intervention. Baseline data were collected using a lunch box audit to assess the frequency of children with fresh fruit, water and sweet drinks, either brought from home or selected from canteen lunch orders. The lunch box audit was repeated periodically for up to 2 years following programme implementation to assess the sustainability of dietary changes. Across all participating schools, significant increases between 25 and 50% were observed in the proportion of children bringing fresh fruit. Similarly, all schools recorded increases between 15 and 60% in the proportion of students bringing filled water bottles to school and reductions between 8 and 38% in the proportion of children bringing sweet drinks. These significant changes in dietary patterns were sustained for up to 2 years following programme implementation. Targeting key nutrition behaviours and using the HPS framework is an effective and simple approach which could be readily implemented in similar childhood settings. Effective strategies include facilitating organizational change within the school; integrating curriculum activities; formalizing school policy and establishing project partnerships with local community nutrition and dietetic services.

    A modified larval migration inhibition assay was used to determine if redberry juniper (Juniperus pinchotii Sudw.) can reduce Haemonchus contortus in vitro motility and increase ivermectin (IVM) efficacy. Ruminal fluid was mixed with buffer solution and either no material (CNTL) or Tifton 85 Bermudagrass hay (T85), dried juniper (DRY), fresh juniper (FRE), or distilled juniper terpenoid oil (OIL) to make treatment solutions and anaerobically incubated for 16 h. For Trial 1, larvae were incubated in CNTL, T85, DRY, or IVM. During Trial 2, larvae were incubated in CNTL, DRY, FRE, or OIL for 4h. Trials 3 (CNTL or OIL) and 4 (CNTL, DRY or FRE) evaluated larvae after incubation in treatment solution for 2h, then incubated an additional 2h in various IVM doses (0, 0.1, 1, 3, and 6 μg/mL IVM) and placed onto a screen. Larvae that passed through the 20-μm screen within a 96-well plate were considered motile. Larvae incubated in CNTL or T85 had similar (P=0.12) motility, but larvae incubated in DRY were less (P<0.02) motile than larvae incubated in CNTL or T85 (Trial 1). During Trial 2, adding DRY, FRE, or OIL reduced (P<0.001) larval motility as compared to CNTL. A treatment×IVM dose interaction (P=0.02) was observed during Trial 3, due to OIL unexpectedly decreasing IMV efficacy at IVM concentrations of 1 (P=0.07), 3, and 6 (P<0.002)μg/mL. No treatment×IVM dose interaction (P=0.57) was observed during Trial 4, but larvae incubated in DRY had less (P<0.004) total motility than larvae incubated in CNTL or FRE. Juniper forage material reduced in vitro H. contortus larval motility, but IVM efficacy was increased only by initially incubating larvae in DRY.

    Abstract Oncolytic adenoviruses are anticancer agents that replicate within tumors and spread to uninfected tumor cells, amplifying the anticancer effect of initial transduction. We tested whether coating the viral particle with polyethylene glycol (PEG) could reduce transduction of hepatocytes and hepatotoxicity after systemic (intravenous) administration of oncolytic adenovirus serotype 5 (Ad5). Conjugating Ad5 with high molecular weight 20-kDa PEG but not with 5-kDa PEG reduced hepatocyte transduction and hepatotoxicity after intravenous injection. PEGylation with 20-kDa PEG was as efficient at detargeting adenovirus from Kupffer cells and hepatocytes as virus predosing and warfarin. Bioluminescence imaging of virus distribution in two xenograft tumor models in nude mice demonstrated that PEGylation with 20-kDa PEG reduced liver infection 19- to 90-fold. Tumor transduction levels were similar for vectors PEGylated with 20-kDa PEG and unPEGylated vectors. Anticancer efficacy after a single intravenous injection was retained at the level of unmodified vector in large established prostate carcinoma xenografts, resulting in complete elimination of tumors in all animals and long-term tumor-free survival. Anticancer efficacy after a single intravenous injection was increased in large established hepatocellular carcinoma xenografts, resulting in significant prolongation of survival as compared with unmodified vector. The increase in efficacy was comparable to that obtained with predosing and warfarin pretreatment, significantly extending the median of survival. Shielding adenovirus with 20-kDa PEG may be a useful approach to improve the therapeutic window of oncolytic adenovirus after systemic delivery to primary and metastatic tumor sites. PMID:19469693

    The 2009 World Health Organization (WHO) Guidelines on hand hygiene in health care recommend alcohol-based hand rubs for both hygienic and pre-surgical hand treatment. Two formulations based on ethanol 80% v/v and 2-propanol 75% v/v are proposed for local preparation in healthcare settings where commercial products are not available or too expensive. Both formulations and our suggested modifications (using mass rather than volume percent concentrations) were evaluated for their conformity with the efficacy requirements of the forthcoming amendment of the European Norm (EN) 12791, i.e. non-inferiority of a product when compared with a reference procedure (1-propanol 60% v/v for 3 min) immediately and 3 h after antisepsis. In this study, the WHO-recommended formulations were tested for 3 min and 5 min. Neither formulation met the efficacy requirements of EN 12791 with 3 min application. Increasing the respective concentrations to 80 w/w (85% v/v) and 75 w/w (80% v/v), together with a prolonged application of 5 min, rendered the immediate effect of both formulations non-inferior to the reference antisepsis procedure. This was not the case with the 3h effect, which remained significantly inferior to the reference. Although the original formulations do not meet the efficacy requirements of EN 12791, the clinical significance of this finding deserves further clinical trials. To comply with the requirement of EN 12791, an amendment to the formulations is possible by increasing the alcohol concentrations through changing volume into mass percent and prolonging the duration of application from 3 min to 5 min.

    2017-01-01

    Objective To investigate the efficacy of portable microcurrent therapy device (PMTD) of the hip internal rotators in the treatment of in-toeing gait caused by increased femoral anteversion in children over 8 years of age. Methods Eleven children (22 legs; 4 boys and 7 girls; mean age, 10.4±1.6 years) with in-toeing gait caused by increased femoral anteversion were included in the present study. All children received 60 minutes of PMTD (intensity, 25 µA; frequency, 8 Hz) applied to the hip internal rotators daily for 4 weeks. Hip internal rotation (IR) angle, external rotation (ER) angle, and midmalleolar-second toe angle (MSTA) measurement during stance phase at transverse plane and Family Satisfaction Questionnaire, frequency of tripping and fatigue like pains about the PMTD were performed before treatment and at 4 weeks after initial PMTD treatment. Paired t-test and Fisher exact test were used for statistical analysis. Results Hip IR/ER/MSTA was 70.3°±5.4°/20.1°±5.5°/–11.4°±2.7°, and 55.7°±7.8°/33.6°±8.2°/–2.6°±3.8° before treatment and at 4 weeks after initial PMTD treatment, respectively (p<0.01). Ten of 11 (91%) children's family stated that they were generally satisfied with the PMTD treatment. The frequency of tripping and fatigue like pains was significantly lower at 4 weeks after PMTD treatment (p<0.05). Excellent inter-rater and intra-rater reliability was observed for repeated MSTA measurements between the examiners (k=0.91–0.96 and k=0.93–0.99), respectively. Conclusion PMTD of the hip internal rotators can be effective in improving the gait pattern of children with in-toeing gait caused by increased femoral anteversion. PMID:28289642

    Observational research suggests that in children with cerebral palsy, the altered arm swing is linked to instability during walking. Therefore, the current study investigates whether children with cerebral palsy use their arms more than typically developing children, to enhance gait stability. Evidence also suggests an influence of walking speed on gait stability. Moreover, previous research highlighted a link between walking speed and arm swing. Hence, the experiment aimed to explore differences between typically developing children and children with cerebral palsy taking into account the combined influence of restricting arm swing and increasing walking speed on gait stability. Spatiotemporal gait characteristics, trunk movement parameters and margins of stability were obtained using three dimensional gait analysis to assess gait stability of 26 children with cerebral palsy and 24 typically developing children. Four walking conditions were evaluated: (i) free arm swing and preferred walking speed; (ii) restricted arm swing and preferred walking speed; (iii) free arm swing and high walking speed; and (iv) restricted arm swing and high walking speed. Double support time and trunk acceleration variability increased more when arm swing was restricted in children with bilateral cerebral palsy compared to typically developing children and children with unilateral cerebral palsy. Trunk sway velocity increased more when walking speed was increased in children with unilateral cerebral palsy compared to children with bilateral cerebral palsy and typically developing children and in children with bilateral cerebral palsy compared to typically developing children. Trunk sway velocity increased more when both arm swing was restricted and walking speed was increased in children with bilateral cerebral palsy compared to typically developing children.

    The addition of recombinant human growth hormone (rhGH) to GnRH agonist (GnRHa) to treat central precocious puberty (CPP) is controversial. We systemically reviewed and evaluated the efficacy and safety of the rhGH and GnRHa adjunctive therapy in Chinese children with CPP and assessed the influence of age and therapy duration on the efficacy of the combined treatment. A total of 464 patients were included from 14 studies. Compared with baseline, administration of GnRHa plus rhGH led to a significant increase in height, predicted adult height (PAH) and height standard deviation for bone age (HtSDS-BA), corresponding to a weighted mean difference (WMD) (95%CI) of 9.06 cm (6.41, 11.70), 6.5 cm (4.47, 8.52), and 0.86 (0.58, 1.14) respectively. Subgroup analysis showed the combined therapy had increased efficacy in subjects with initial treatment age younger than 10 years old or with treatment lasting over 12 months. Compared with GnRHa alone treatment, the combined treatment led to a significant increase in height, PAH and HtSDS-BA, corresponding to a WMD (95% CI) of 3.56 cm (2.54, 4.57), 3.76 cm (3.19, 4.34) and 0.56 (0.43, 0.69). The combined treatment exhibited no safety concerns. Our findings may aid clinicians in making treatment decisions for children with CPP. PMID:27072597

We divided 123 children undergoing flexible bronchoscopy with DEX-RF or dexmedetomidine-propofol into 2 groups: Group DR (n = 63, DEX infusion at 1.0 μg kg−1 for 10 minutes, then adjusted to 0.5–0.7 μg kg−1 h−1; RF infusion at 1.0 μg kg−1 for 5 minutes, then adjusted to 0.05–0.2 μg kg−1 min−1), Group DP (n = 60, DEX infusion at 1.0 μg kg−1 for 10 minutes, then adjusted to 0.5–0.7 μg kg−1 h−1; propofol infusion at 10 μg kg−1 for 5 minutes, then adjusted to 0.05–0.1 μg kg−1 min−1). Ramsay sedation scale of the 2 groups was maintained at 3. Anesthesia onset time; total number of intraoperative patient movements; hemodynamics; total cumulative dose of DEX; amount of and time to first-dose rescue midazolam and lidocaine; postoperative recovery time; adverse events; and bronchoscopist satisfaction score were recorded. Anesthesia onset time was significantly shorter in DP (8.22 ± 2.48 vs 12.25 ± 6.43 minutes, respectively, for DP, DR, P = 0.015). The perioperative hemodynamic profile was more stable in DR than DP group. More children moved during flexible bronchoscopy in DP group (P = 0.009). Total dose of rescue midazolam and lidocaine was significantly higher in DR than in DP (P < 0.001). Similarly, the time to first dose of rescue midazolam and lidocaine was significantly longer in DP than in DR (P < 0.001). Total cumulative dose of DEX was more in DR than DP group (P < 0.001). The time to recovery for discharge from the postanesthesia care unit

    There has been increased research interest in the use of active video games (in which players physically interact with images onscreen) as a means to promote physical activity in children. The aim of this review was to assess active video games as a means of increasing energy expenditure and physical activity behavior in children. Studies were obtained from computerized searches of multiple electronic bibliographic databases. The last search was conducted in December 2008. Eleven studies focused on the quantification of the energy cost associated with playing active video games, and eight studies focused on the utility of active video games as an intervention to increase physical activity in children. Compared with traditional nonactive video games, active video games elicited greater energy expenditure, which was similar in intensity to mild to moderate intensity physical activity. The intervention studies indicate that active video games may have the potential to increase free-living physical activity and improve body composition in children; however, methodological limitations prevent definitive conclusions. Future research should focus on larger, methodologically sound intervention trials to provide definitive answers as to whether this technology is effective in promoting long-term physical activity in children.

  6. Equine-Assisted Occupational Therapy: Increasing Engagement for Children With Autism Spectrum Disorder.

    Engagement in meaningful activities is essential to development and is often reduced in children with autism spectrum disorder (ASD) who have limited engagement in activities or relationships. A multiple-baseline design was used with 7 children with ASD ages 4-8 yr to assess the effect of including a horse in occupational therapy intervention on task engagement. The children showed improvements in engagement. Including horses in occupational therapy sessions may be a valuable addition to conventional treatments to increase task engagement of children with ASD. Factors related to the environment, therapeutic strategies, and individual participation need to be considered in understanding why this intervention may be effective and developing a theoretical basis for implementation.

    Longitudinal results for a randomized-controlled trial (RCT) assessing the impact of increasing preschoolers' attention to print during reading are reported. Four-year-old children (N = 550) in 85 classrooms experienced a 30-week shared reading program implemented by their teachers. Children in experimental classrooms experienced shared-book readings 2 or 4 times per week during which their teachers verbally and nonverbally referenced print. Children in comparison classrooms experienced their teachers' typical book reading style. Longitudinal results (n = 356, 366) showed that use of print references had significant impacts on children's early literacy skills (reading, spelling, comprehension) for 2 years following the RCT's conclusion. Results indicate a causal relation between early print knowledge and later literacy skills and have important implications concerning the primary prevention of reading difficulties.

    The study was conducted to examine relationships between affectionate behavior in children with Asperger syndrome and variables likely to influence its expression (e.g., tactile sensitivity, social ability). It also evaluated the impact of a cognitive behavioral intervention that aimed to improve a child's understanding and expression of affection. Twenty-one children, aged 7 to 12 years, participated in the trial. The results showed significant correlations between measures of affection and tactile sensitivity and social ability. After attending the 5-week program, parents identified significant increases in the appropriateness of children's affectionate behavior both towards immediate family and people outside the immediate family, despite reporting no significant changes in their child's general difficulties with affectionate behavior. There was a significant improvement in children's understanding of the purpose of affection. The findings are discussed as well as the limitations of the study. PMID:22937243

    Although spinal cord stimulation (SCS) is an established treatment for chronic neuropathic pain, pain relief is still not successful in a large group of patients. We suggest that the success of SCS may be related to the timing of SCS during the development of chronic neuropathic pain. We therefore compared the effect of SCS applied after 24h of neuropathic pain (early SCS) and after 16days of neuropathic pain (late SCS). For early SCS, male Sprague-Dawley rats (n=13) were implanted with an SCS device, followed by a partial ligation of the sciatic nerve. Using von Frey monofilaments, tactile allodynia was assessed 24h after ligation. Animals with tactile allodynia received 30min of SCS. Withdrawal thresholds were assessed just before SCS, during SCS and until the return to pre-stimulation withdrawal threshold. Results were compared with the data from late SCS (n=29). Out of the 13 allodynic animals that received early SCS, 10 (77%) responded to SCS with significantly increased withdrawal thresholds, compared to 38% in the late SCS group. The increase of the withdrawal threshold in the early SCS group could still be noticed 90min after termination of SCS. In more than half of these animals, pre-stimulation withdrawal thresholds were reached only the next day. Early SCS resulted in an increased number of responders to SCS and furthermore an increased duration of the effect of SCS as compared to late SCS. Early SCS treatment of neuropathic rats is more effective as compared to the late SCS treatment.

    The purpose of this study was to compare the efficacy of melodic based communication therapy (MBCT) to traditional speech and language therapy for eliciting speech in nonverbal children with autism. Participants were 12 nonverbal children with autism ages 5 through 7 randomly assigned to either treatment group. Both groups made significant progress after treatment. The MBCT group progressed significantly in number of verbal attempts after weeks 1 through 4 and number of correct words after weeks 1 and 3, while the traditional group progressed significantly after weeks 4 and 5. No significant differences in number of verbal attempts or number of correct words were noted between groups following treatment. A significant number of new words were heard in the home environment for the MBCT group (p = .04). Participants in the MBCT group had more imitative attempts (p = .03). MBCT appears to be a valid form of intervention for children with autism.

    Objective: The objective of this study is to evaluate the link between excess iodine intake as evidenced by increased urinary iodine excretion (UIE) and autoimmune thyroiditis in children and to assess the correlation between UIE and thyroid microsomal antibody (thyroid peroxidase [TPO]) titers in children. Materials and Methods: All children with goiter between age group 6 and 12 years, were subjected to blood tests for free thyroxine, thyroid stimulating hormone, and TPO antibody, fine needle aspiration was advised for all children with goiter. Forty-three children with confirmed autoimmune thyroiditis served as cases, and 43 children with euthyroid goiter with workup negative for autoimmune thyroiditis and iodine deficiency were enrolled as controls. UIE was estimated in spot urine sample for both cases and controls. The levels of urinary iodine were compared between cases and controls. Results: The levels of urinary iodine were significantly higher in children with autoimmune thyroiditis as compared with control. There was a positive correlation between UIE and antimicrosomal antibody titers among cases. Among cases 65% children had subclinical hypothyroidism, 27.9% had overt hypothyroidism and 7% of cases, and 100% of controls had euthyroid functional status. Excessive (≥300 μg/L) UIE was strongly associated with autoimmune thyroiditis. If the UIE level is ≥ 300 μg/L, then there is 17.94 times higher chance of having amiodarone-induced thyrotoxicosis than those who have UIE level < 300 μg/L (P < 0.001). Conclusions: A possible association between increased iodine intake and autoimmune thyroiditis was found in this study. Excessive iodine intake may trigger thyroid autoimmunity and eventually thyroid hypofunction. PMID:28217504

  14. A critical eye: praise directed toward traits increases children's eye fixations on errors and decreases motivation.

    2012-12-01

    Although there is evidence that praise of different types (i.e., generic vs. nongeneric) influences motivation, it is unclear how this occurs. Generic praise (e.g., "You are smart") conveys that a child possesses a trait responsible for their performance, whereas nongeneric praise (e.g., "You worked hard") conveys that performance is effort-based. Because praise conveys the basis for success, praise may change the interpretation and salience of errors. Specifically, generic praise may highlight the threatening nature of error (i.e., the child does not possess this trait). Because attention is drawn to threats in the environment, we expected generic praise to increase attention to error. We used eyetracking to measure implicit responses to errors (i.e., visual attention: fixation counts and durations) in order to determine the relation between visual attention and verbal reports of motivation (persistence and self-evaluations) in 30 four- to seven-year-old children. Children first saw pictures attributed to them, for which they received either generic or nongeneric praise. The children then saw pictures attributed to them that contained errors--that is, missing features. As a pretest and posttest, the children saw pictures that were "drawn by other children," half of which contained errors. The results indicated that children who received generic praise ("you are a good drawer") produced more and longer fixations on errors, both their "own" and on "other children's," than did children who received nongeneric praise ("you did a good job drawing"). More fixations on errors were related to lower persistence and lower self-evaluations. These results suggest that generic praise increases attention to errors because error threatens the possession of a positive trait.

    School-age children have attracted relatively little attention as a group in need of special measures to protect them against malaria. However, increasing success in lowering the level of malaria transmission in many previously highly endemic areas will result in children acquiring immunity to malaria later in life than has been the case in the past. Thus, it can be anticipated that in the coming years there will be an increase in the incidence of both uncomplicated and severe malaria in school-age children in many previously highly endemic areas. In this review, which focuses primarily on Africa, recent data on the prevalence of malaria parasitaemia and on the incidence of clinical malaria in African school-age children are presented and evidence that malaria adversely effects school performance is reviewed. Long-lasting insecticide treated bednets (LLIN) are an effective method of malaria control but several studies have shown that school-age children use LLINs less frequently than other population groups. Antimalarial drugs are being used in different ways to control malaria in school-age children including screening and treatment and intermittent preventive treatment. Some studies of chemoprevention in school-age children have shown reductions in anaemia and improved school performance but this has not been the case in all trials and more research is needed to identify the situations in which chemoprevention is likely to be most effective and, in these situations, which type of intervention should be used. In the longer term, malaria vaccines may have an important role in protecting this important section of the community from malaria. Regardless of the control approach selected, it is important this is incorporated into the overall programme of measures being undertaken to enhance the health of African school-age children.

    Probiotic milk has been previously demonstrated to reduce the number of respiratory infections (RI) among children attending day care centres. Thus, this pilot study was aimed to assess the efficacy and the safety of 3 month treatment with Bacillus clausii in the prevention of recurrent respiratory infections (RRI) in children. Eighty children with RRI were studied: 40 of them were randomly treated with B. clausii for 3 months, and followed up for further 3 months; 40 were included in the control group during the same period. Children treated with B. clausii had shorter duration of RI in comparison with the control group both during the treatment phase (mean 11.7 days vs 14.37; p=0.037) and the follow-up period (mean 6.6 days vs 10.92; p=0.049). This effect was evident also in allergic children during the follow-up. In conclusion, this pilot study provides the first preliminary evidence that B. clausii may exert a significant and persistent impact on RI in children and is safe and well tolerated.

    This study examined the benefits of adding game elements to standard computerized working memory (WM) training. Specifically, it examined whether game elements would enhance motivation and training performance of children with ADHD, and whether it would improve training efficacy. A total of 51 children with ADHD aged between 7 and 12 years were randomly assigned to WM training in a gaming format or to regular WM training that was not in a gaming format. Both groups completed three weekly sessions of WM training. Children using the game version of the WM training showed greater motivation (i.e., more time training), better training performance (i.e., more sequences reproduced and fewer errors), and better WM (i.e., higher scores on a WM task) at post-training than children using the regular WM training. Results are discussed in terms of executive functions and reinforcement models of ADHD. It is concluded that WM training with game elements significantly improves the motivation, training performance, and working memory of children with ADHD. The findings of this study are encouraging and may have wide-reaching practical implications in terms of the role of game elements in the design and implementation of new intervention efforts for children with ADHD.

    Parenting self-efficacy (PSE) has been positively linked to children's adjustment and negatively associated with maternal depression. However, most PSE research has been cross-sectional, limited to predominantly white, middle-class samples, and has not examined potential mechanisms underlying associations of PSE with children's behavior. The present study investigates: (1) how PSE changes over time, (2) the relationship between age 2 PSE and children's behavior problems 2 years later, and (3) the potential mediating role of maternal depression in relation to the association between PSE and child problem behavior. Participants are 652 ethnically and geographically diverse mothers and their children, at high risk for conduct problems. PSE increased between ages 2 and 4 and higher initial levels predicted lower caregiver-reported age 4 conduct problems after controlling for problem behavior at age 2. The relationship between PSE and later conduct problems was mediated, however, by maternal depression. These findings suggest maternal depression as a potential disruptor of caregiver confidence in early childhood, which has implications for the design and focus of parenting interventions.

    Geologic carbon capture and storage involves the injection of CO2 into underground formations such as brine aquifers where microbe-rock-fluid interactions will occur. These interactions may be important for the long-term fate of the injected CO2 particularly near well bores and potential leakage pathways. Herein, concepts and results are presented from bench to meso-scale experiments focusing on the utility of attached microorganisms and biofilms to enhance storage security of injected CO2. Batch and flow experiments at atmospheric and geologic CO2storage-relevant pressures have demonstrated the ability of microbial biofilms to decrease the permeability of natural and artificial porous media, survive the exposure to scCO2, and facilitate the conversion of CO2 into long-term stable carbonate phases as well as increase the solubility of CO2 in brines. Recently, the microbially catalyzed process of ureolysis has been investigated for the potential to promote calcium carbonate mineralization in subsurface reservoirs using native or introduced ureolytic microorganisms, which increase the saturation state of CaCO3 via the hydrolysis of urea. The anticipated applications for this biomineralization process in the subsurface include sealing microfractures and CO2 leakage pathways for increased security of geologic carbon storage. Recent work has focused on facilitating this biomineralization process in large scale (74 cm diameter, 38 cm high sandstone) radial flow systems under ambient and subsurface relevant pressures with the goal of developing injection strategies suited for field scale deployment. Methods for microscopic and macroscopic visualization of relevant processes, such as growth of microbial biofilms, their interactions with minerals and influence on pore spaces in porous media reactors are being developed and have been used to calibrate reactive transport models. As a result, these models are being used to predict the effect of biological processes on CO2

    2017-01-01

    We investigated the efficacy and tolerability of solifenacin 5 mg fixed dose in children with newly diagnosed idiopathic overactive bladder (OAB). A total of 34 children (male/female patients = 16/18) aged under 13 years (mean age: 7.2 ± 2.3; range: 5–12) who were newly diagnosed with OAB from January 2012 to September 2014 were prospectively evaluated with open-label protocol. All patients were treated with solifenacin 5 mg fixed dose once daily for at least 4 weeks. The efficacy and tolerability of solifenacin were evaluated 4, 8, and 12 weeks after the initiation of treatment. The mean voiding frequency during daytime was decreased from 9.4 ± 3.0 to 6.5 ± 2.3 times after the 12-week treatment (P < 0.001). The mean total OAB symptom score (OABSS) decreased from 7.7 ± 4.2 to 3.1 ± 3.1 after the 12-week treatment (P < 0.001). The urgency and urgency urinary incontinence (UUI) domains significantly improved from the 12-week treatment, and complete resolution of urgency occurred in 38.9% of patients and the percentage of children with UUI among urgent patients decreased from 79.4% to 57.1%. According to 3-day voiding diaries, the average bladder capacity increased from 90.4 ± 44.4 to 156.2 ± 67.3 mL (P < 0.001). Drug-induced adverse effects (AEs) were reported in 7 patients (20.6%). Our results indicate that solifenacin 5 mg fixed dose is effective against OAB symptoms, and its tolerability is acceptable without significant AEs in children with OAB. PMID:28049246

    Postural orthostatic tachycardia syndrome (POTS) is common, and has a serious impact on children's quality of life. Midodrine hydrochloride, an α1-adrenoreceptor agonist, is an effective treatment. The study was designed to examine the therapeutic efficacy of midodrine hydrochloride by quantifying changes in blood pressure during the head-up test (HUT), in children with POTS. Overall, 104 out of 110 children with POTS were treated with midodrine hydrochloride and successfully followed-up. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) changes were analyzed during the HUT. In a retrospective analysis, a receiver operating characteristic (ROC) curve was used to analyze the therapeutic predictive value of pre-treatment changes in SBP, DBP, and a combination of both, from the supine position to standing, in the subjects. The increase of SBP and DBP from the supine position to standing in responders were significantly lower than that of the non-responders. The ROC curve showed that midodrine hydrochloride for children with POTS would be predicted to be effective when the pre-treatment increase of SBP was ≤ 0 mmHg, or when the pre-treatment increase of DBP was ≤ 6.5 mmHg (from the supine position to standing), yielding a sensitivity of 72% and specificity of 88%. The area under the curve was 0.744 and 0.809, respectively. Hence, the results suggested that looking at the changes in blood pressure during the HUT was useful in predicting the response to midodrine hydrochloride in children with POTS.

    The infiltrative lung diseases are a class of irreversible, non-neoplastic lung pathologies requiring regular follow-up with CT imaging. Quantifying the evolution of the patient status imposes the development of automated classification tools for lung texture. For the large majority of CAD systems, such classification relies on a two-dimensional analysis of axial CT images. In a previously developed CAD system, we proposed a fully-3D approach exploiting a multi-scale morphological analysis which showed good performance in detecting diseased areas, but with a major drawback consisting of sometimes overestimating the pathological areas and mixing different type of lung patterns. This paper proposes a combination of the existing CAD system with the classification outcome provided by a convolutional network, specifically tuned-up, in order to increase the specificity of the classification and the confidence to diagnosis. The advantage of using a deep learning approach is a better regularization of the classification output (because of a deeper insight into a given pathological class over a large series of samples) where the previous system is extra-sensitive due to the multi-scale response on patient-specific, localized patterns. In a preliminary evaluation, the combined approach was tested on a 10 patient database of various lung pathologies, showing a sharp increase of true detections.

    Using a combination of an alternating treatment and double-blind placebo-controlled drug design, the independent and combined effects of two behavioral interventions and two doses of methylphenidate (MPH) in 3 children with Attention Deficit Hyperactivity Disorder (ADHD) and mental retardation (MR) were assessed. In this single subject design, 2 of the 3 subjects responded positively to medication as measured by increased on-task behavior. The first behavioral intervention, a token economy for on-task behavior, was ineffective for increasing either on-task behavior or work accuracy when combined with placebo. However, improvement in work accuracy was realized with implementation of a second behavioral intervention that specifically targeted accuracy independent of drug conditions. The current findings highlight both the positive effects and limitations of the two commonly used treatment modalities for ADHD. Future studies should continue to extend this area of investigative efforts to produce more data-based knowledge as to the appropriate doses of treatment, both pharmacological and behavioral, with children with both ADHD and mental retardation.

    This quasi-experimental study examines the impact of Idaho's wellness incentive program, which rewards children with CHIP (Children's Health Insurance Programs) who are up-to-date with well-child visits with $30 in credits per quarter for use toward their CHIP premiums. Between baseline and the second year of implementation, the percentage of CHIP children who were up-to-date with well-child visits increased by 116% (from 23% to 49%), compared with a 13% increase (from 29% to 32%) among children with Medicaid, who were not eligible for the incentive. The incentive program had a greater impact on children who were recommended to have one annual well-child visit compared with those recommended to have two to four annual visits. The program was not, however, more effective for those whose premiums were fully covered by the reward compared with those whose premiums were partially covered. This study provides encouraging evidence to states about using consumer financial incentives for increasing preventive care use.

    In response to the inherent dynamic nature of the oceans and continuing difficulty in managing ecosystem impacts of fisheries, interest in the concept of dynamic ocean management, or real-time management of ocean resources, has accelerated in the last several years. However, scientists have yet to quantitatively assess the efficiency of dynamic management over static management. Of particular interest is how scale influences effectiveness, both in terms of how it reflects underlying ecological processes and how this relates to potential efficiency gains. Here, we address the empirical evidence gap and further the ecological theory underpinning dynamic management. We illustrate, through the simulation of closures across a range of spatiotemporal scales, that dynamic ocean management can address previously intractable problems at scales associated with coactive and social patterns (e.g., competition, predation, niche partitioning, parasitism, and social aggregations). Furthermore, it can significantly improve the efficiency of management: as the resolution of the closures used increases (i.e., as the closures become more targeted), the percentage of target catch forgone or displaced decreases, the reduction ratio (bycatch/catch) increases, and the total time–area required to achieve the desired bycatch reduction decreases. In the scenario examined, coarser scale management measures (annual time–area closures and monthly full-fishery closures) would displace up to four to five times the target catch and require 100–200 times more square kilometer-days of closure than dynamic measures (grid-based closures and move-on rules). To achieve similar reductions in juvenile bycatch, the fishery would forgo or displace between USD 15–52 million in landings using a static approach over a dynamic management approach. PMID:26729885

    In response to the inherent dynamic nature of the oceans and continuing difficulty in managing ecosystem impacts of fisheries, interest in the concept of dynamic ocean management, or real-time management of ocean resources, has accelerated in the last several years. However, scientists have yet to quantitatively assess the efficiency of dynamic management over static management. Of particular interest is how scale influences effectiveness, both in terms of how it reflects underlying ecological processes and how this relates to potential efficiency gains. Here, we address the empirical evidence gap and further the ecological theory underpinning dynamic management. We illustrate, through the simulation of closures across a range of spatiotemporal scales, that dynamic ocean management can address previously intractable problems at scales associated with coactive and social patterns (e.g., competition, predation, niche partitioning, parasitism, and social aggregations). Furthermore, it can significantly improve the efficiency of management: as the resolution of the closures used increases (i.e., as the closures become more targeted), the percentage of target catch forgone or displaced decreases, the reduction ratio (bycatch/catch) increases, and the total time-area required to achieve the desired bycatch reduction decreases.

    Working memory (WM) - temporary storage and manipulation of information in the mind - is a key component of cognitive maturation, and structural brain changes throughout development are associated with refinements in WM. Recent functional neuroimaging studies have shown that there is greater activation in prefrontal and parietal brain regions with increasing age, with adults showing more refined, localized patterns of activations. However, few studies have investigated the neural basis of verbal WM development, as the majority of reports examine visuo-spatial WM. We used fMRI and a 1-back verbal WM task with six levels of difficulty to examine the neurodevelopmental changes in WM function in 40 participants, twenty-four children (ages 9-15 yr) and sixteen young adults (ages 20-25 yr). Children and adults both demonstrated an opposing system of cognitive processes with increasing cognitive demand, where areas related to WM (frontal and parietal regions) increased in activity, and areas associated with the default mode network decreased in activity. Although there were many similarities in the neural activation patterns associated with increasing verbal WM capacity in children and adults, significant changes in the fMRI responses were seen with age. Adults showed greater load-dependent changes than children in WM in the bilateral superior parietal gyri, inferior frontal and left middle frontal gyri and right cerebellum. Compared to children, adults also showed greater decreasing activation across WM load in the bilateral anterior cingulate, anterior medial prefrontal gyrus, right superior lateral temporal gyrus and left posterior cingulate. These results demonstrate that while children and adults activate similar neural networks in response to verbal WM tasks, the extent to which they rely on these areas in response to increasing cognitive load evolves between childhood and adulthood.

    Spirulina is an alga rich in high-quality protein and carotenoids. It is unclear whether spirulina can improve the total-body vitamin A stores of school-age children in China with a high prevalence of vitamin A malnutrition. We aimed to evaluate the efficacy of spirulina in improving the total-body vitamin A stores of school-age children in rural areas of China when they consumed spirulina in their daily meals. A total of 228 children (6-11 years) were recruited and randomly divided into three groups supplemented with 4 g (containing 4·18 µg β-carotene), 2 g (containing 2·54 µg β-carotene) or 0 g spirulina 5 d/week for 10 weeks, respectively. Before and after the intervention period, each child was given 0·5 mg [(2)H4]retinyl acetate and [(2)H8]retinyl acetate, respectively. To assess vitamin A stores, blood samples (3 ml) were collected on the third and the twenty-first day after each labelled retinyl acetate dose for a retinol enrichment analysis using a GC mass spectrometer. The concentrations of retinol and β-carotene in serum samples were also determined by using HPLC. After the 10-week intervention, serum β-carotene concentrations of children with 2 or 4 g spirulina supplement increased by 0·160 and 0·389 µmmol/l, respectively. Total-body vitamin A stores increased significantly, with a median increase of 0·160 mmol in children taking 2 g spirulina and of 0·279 mmol in children taking 4 g spirulina. Spirulina is a good dietary source of β-carotene, which may effectively increase the total-body vitamin A stores of Chinese school-age children.

    The goal of this investigation was to clarify the question of whether targeting Enox1 in tumor stroma would synergistically enhance the survival of tumor-bearing mice treated with fractionated radiotherapy. Enox1, a NADH oxidase, is expressed in tumor vasculature and stroma. However, it is not expressed in many tumor types, including HT-29 colorectal carcinoma cells. Pharmacological inhibition of Enox1 in endothelial cells inhibited repair of DNA double strand breaks, as measured by γH2AX and 53BP1 foci formation, as well as neutral comet assays. For 4 consecutive days athymic mice bearing HT-29 hindlimb xenografts were injected with a small molecule inhibitor of Enox1 or solvent control. Tumors were then administered 2 Gy of x-rays. On day 5 tumors were administered a single ‘top-up’ fraction of 30 Gy, the purpose of which was to amplify intrinsic differences in the radiation fractionation regimen produced by Enox1 targeting. Pharmacological targeting of Enox1 resulted in 80% of the tumor-bearing mice surviving at 90 days compared to only 40% of tumor-bearing mice treated with solvent control. The increase in survival was not a consequence of reoxygenation, as measured by pimonidazole immunostaining. These results are interpreted to indicate that targeting of Enox1 in tumor stroma significantly enhances the effectiveness of 2 Gy fractionated radiotherapy and identifies Enox1 as a potential therapeutic target.

    Serum IgD concentrations were measured in 39 children with Henoch Schonlein purpura (HSP) and 40 control children by means of radial immunodiffusion. Serum IgG, IgA and IgM concentrations in the HSP patients were measured by nephelometry. The geometric mean IgD concentration in children with HSP (16.7 microg/ml) was significantly higher than in control children (9.1 microg/ml; P=0.03). Serial testing in 10 HSP patients revealed no significant change in IgD concentrations over periods ranging from 1 to 12 months. There was no relationship between IgD and IgA concentrations in the HSP patients. Nineteen of the 39 HSP patients (49%) had nephritis. The mean IgD concentration in patients with nephritis (10.7 microg/ml) did not differ from control values, but was significantly lower than the mean IgD level in the remaining 20 patients who did not have nephritis (25.4 microg/ml; P=0.02). These results indicate that serum IgD levels are increased in children with HSP who did not have nephritis. IgD concentrations in patients with nephritis were similar to levels in control children.

    This single-blind, placebo-controlled study assesses the efficacy of synergic administration of intravenous laser blood irradiation (ILBI) and etanercept in selected subtypes of juvenile idiopathic arthritis (JIA). Etanercept is a tumor necrosis factor alpha blocking agent with recognized importance in JIA. Laser radiation has immunomodulatory effects in animal and human studies. Fourteen patients (Group I) received ILBI and 9 patients (Group II) received placebo laser. ILBI was performed in addition to ongoing JIA medication, including etanercept. ILBI was administrated in 3 sets of 5 consecutive daily sessions, with a 7-week interval between every set of sessions. Evaluation was performed using ACR (American College of Rheumatology) Pediatric Criteria (ACR Pedi) at study enrollment and at 10 and 20 weeks, respectively. After 10 weeks, 85.7% of the patients in Group I fulfilled Pedi 30 criteria, compared to only 55.6% of the patients in Group II. After 20 weeks, all patients in both groups had a Pedi 30 response. In Group I, 92.8% of the subjects met the Pedi 50 response, compared to only 55.6% in the placebo group. One patient in Group I responded best, fulfilling Pedi 70 criteria. If applied synergistically, ILBI and etanercept would have an increased efficacy in promoting JIA remission. PMID:23990845

    Two series of branched tetramers of the proline-rich antimicrobial peptide (PrAMP), Chex1-Arg20, were prepared to improve antibacterial selectivity and potency against a panel of Gram-negative nosocomial pathogens including Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa. First, tetramerization was achieved by dithiomaleimide (DTM) conjugation of two C-terminal-cysteine bearing dimers that also incorporated C-terminal peptide chemical modification. DTM-linked tetrameric peptides containing a C-terminal hydrazide moiety on each dimer exhibited highly potent activities in the minimum inhibitory concentration (MIC) range of 0.49-2.33 μm. A second series of tetrameric analogues with C-terminal hydrazide modification was prepared by using alternative conjugation linkers including trans-1,4-dibromo-2-butene, α,α'-dibromo-p-xylene, or 6-bismaleimidohexane to determine the effect of length on activity. Each displayed potent and broadened activity against Gram-negative nosocomial pathogens, particularly the butene-linked tetrameric hydrazide. Remarkably, the greatest MIC activity is against P. aeruginosa (0.77 μm/8 μg mL(-1) ) where the monomer is inactive. None of these peptides showed any cytotoxicity to mammalian cells up to 25 times the MIC. A diffusion NMR study of the tetrameric hydrazides showed that the more active antibacterial analogues were those with a more compact structure having smaller hydrodynamic radii. The results show that C-terminal PrAMP hydrazidation together with its rational tetramerization is an effective means for increasing both diversity and potency of PrAMP action.

    Modification of hydrophilic proteins with amphiphilic block copolymers capable of crossing cell membranes is a new strategy to improve protein delivery to the brain. Leptin, a candidate for the treatment of epidemic obesity, has failed in part because of impairment in its transport across the blood–brain barrier (BBB) that develops with obesity. We posit that modification of leptin with poly(ethylene oxide)-b-poly(propylene oxide)-b-poly (ethylene oxide), Pluronic P85 (P85) might permit this protein to penetrate the BBB independently of its transporter, thereby overcoming peripheral leptin resistance. Here we report that peripherally administered leptin–P85 conjugates exhibit biological activity by reducing food intake in mouse models of obesity (ob/ob, and diet-induced obese mouse). We further generated two new leptin–P85 conjugates: one, Lep(ss)–P85(L), containing one P85 chain and another, Lep(ss)–P85(H), containing multiple P85 chains. We report data on their purification, analytical characterization, peripheral and brain pharmacokinetics (PK). Lep(ss)–P85(L) crosses the BBB using the leptin transporter, and exhibits improved peripheral PK along with increased accumulation in the brain compared to unmodified leptin. Lep(ss)–P85(H) also has improved peripheral PK but in a striking difference to the first conjugate penetrates the BBB independently of the leptin transporter via a non-saturable mechanism. The results demonstrate that leptin analogs can be developed through chemical modification of the native leptin with P85 to overcome leptin resistance at the level of the BBB, thus improving the potential for the treatment of obesity.

    Objectives of this study were to determine if a redberry juniper-based diet can reduce fecal egg counts (FEC) and increase ivermectin (IVM) efficacy in IVM-resistant Haemonchus contortus. Predominant genera present were Haemonchus (range 45-100%) and Trichostrongylus (range 0-47%). The FEC reduction for IVM in the ewe flock was 25% (95% confidence intervals 79% to -162%) and confirmed IVM resistance. After natural infection was established, Barbados Blackbelly and St. Croix lambs (n=64, 6 months old) were randomly assigned to pens and fed a pelleted treatment diet (4 pens/treatment and 8 lambs/pen) consisting of traditional feed ingredients mixed with either 30% hay (CNTL) or 30% ground juniper leaves and stems (JUN). Lambs were fed during two periods: Period 1 (days 0-28) and Period 2 (days 28-42). On day 28, half of the lambs from each treatment and pen were treated with IVM orally (0.2 mg/kg), creating four treatment groups: lambs fed CNTL or JUN and either not treated (CNTLn, JUNn) or treated (CNTLi, JUNi) with IVM. During Period 1, lambs fed CNTL had greater (P<0.001) average daily gain than lambs fed JUN, which was probably caused by the CNTL diet having greater protein and less acid detergent fiber, lignin, and condensed tannins than the JUN diet. Lambs had similar (P>0.46) FEC on days 0 and 28, but lambs fed JUN had 69.1% lower (P<0.001) FEC on day 15 as compared to lambs fed CNTL. During Period 2, CNTLi lambs had greater (P<0.05) average daily gain than JUNn and JUNi lambs. Lambs fed JUN and treated with IVM (JUNi) had 66%, 65%, and 61% lower (P<0.05) FEC as compared to CNTLn, CNTLi, and JUNn lambs, respectively. Results suggest that feeding lambs a diet containing 30% redberry juniper reduced FEC and increased IVM efficacy by 65% (JUNi vs. CNTLi). Specific mechanisms involved in increasing IVM efficacy by feeding diets containing bioactive compounds warrants further investigation.

    Resistant starch (RS) has been shown to beneficially affect insulin sensitivity in healthy individuals and those with metabolic syndrome, but its effects on human type 2 diabetes (T2DM) are unknown. This study aimed to determine the effects of increased RS consumption on insulin sensitivity and glucose control and changes in postprandial metabolites and body fat in T2DM. Seventeen individuals with well-controlled T2DM (HbA1c 46.6±2 mmol/mol) consumed, in a random order, either 40 g of type 2 RS (HAM-RS2) or a placebo, daily for 12 weeks with a 12-week washout period in between. AT THE END OF EACH INTERVENTION PERIOD, PARTICIPANTS ATTENDED FOR THREE METABOLIC INVESTIGATIONS: a two-step euglycemic-hyperinsulinemic clamp combined with an infusion of [6,6-(2)H2] glucose, a meal tolerance test (MTT) with arterio-venous sampling across the forearm, and whole-body imaging. HAM-RS2 resulted in significantly lower postprandial glucose concentrations (P=0.045) and a trend for greater glucose uptake across the forearm muscle (P=0.077); however, there was no effect of HAM-RS2 on hepatic or peripheral insulin sensitivity, or on HbA1c. Fasting non-esterified fatty acid (NEFA) concentrations were significantly lower (P=0.004) and NEFA suppression was greater during the clamp with HAM-RS2 (P=0.001). Fasting triglyceride (TG) concentrations and soleus intramuscular TG concentrations were significantly higher following the consumption of HAM-RS2 (P=0.039 and P=0.027 respectively). Although fasting GLP1 concentrations were significantly lower following HAM-RS2 consumption (P=0.049), postprandial GLP1 excursions during the MTT were significantly greater (P=0.009). HAM-RS2 did not improve tissue insulin sensitivity in well-controlled T2DM, but demonstrated beneficial effects on meal handling, possibly due to higher postprandial GLP1.

    Objective: ADHD and asthma are prevalent conditions in childhood, with complex pathophysiology involving genetic-environmental interplay. The study objective is to examine the prevalence of asthma in our ADHD population and explore factors that may increase the risk of developing asthma in children with ADHD. Methods: We retrospectively analyzed the presence of maternal stress during pregnancy and history of asthma in 201 children diagnosed with ADHD. Results: Chi-square analysis indicated significant higher presence of asthma in our ADHD sample compared to Quebec children, χ2(1, N = 201) = 15.37, P<0.001. Only prematurity and stress during pregnancy significantly predicted asthma in a logistic regression model, χ2(2)=23.70, P<0.001, with odds ratios of 10.6 (95% CI: 2.8–39.5) and 3.2 (95% CI: 1.4–7.3), respectively. Conclusion: Children with ADHD have a higher prevalence of asthma than the general Quebec pediatric population. Children with ADHD born prematurely and/or those whose mothers experienced stress during pregnancy have a significantly increased risk of developing asthma. The study highlights the importance of potentially offering social and psychological support to mothers who experienced stress during pregnancy and/or are at risk of delivering prematurely.

    The emerging public health problem of type 2 diabetes in youth reflects increasing rates of childhood obesity. As in adults, type 2 diabetes in children is part of the insulin resistance syndrome that includes hypertension, dyslipidemia and other atherosclerosis risk factors, and hyperandrogenism seen as premature adrenarche and polycystic ovary syndrome. Studies in children document risk factors for type 2 diabetes and associated cardiovascular risk factors, including obesity, family history, diabetic gestation, and underweight or overweight for gestational age. Genetically determined insulin resistance, or limited beta-cell reserve, has been demonstrated in high risk individuals. This genetic background, considered advantageous in a feast and famine existence (the thrifty genotype), is rendered detrimental with abundant food and physical inactivity, a lifestyle demonstrated to be typical of families of children with type 2 diabetes. Case finding in high risk individuals who are asymptomatic may be an appropriate response to the public health challenge of type 2 diabetes in children, because risk factors for cardiovascular disease are already present at the time of diagnosis. Treatment is dictated by the degree of metabolic derangement and symptoms. The only data on the use of oral hypoglycemic agents in children has been with metformin. Prevention efforts will require community and government involvement to reduce obesity and increase physical activity in the child, as well as adult, population.

    Bicycle-related head injuries are an important cause of death and disability, despite the availability of helmets. The objective of this study was to evaluate the effectiveness of a school-based bicycle helmet promotion program in increasing helmet use by children while controlling for secular trends. Two high-income and two low-income schools in an urban Canadian community were selected to receive a bicycle helmet promotion intervention, with the remaining 18 schools serving as controls. Approximately 1800 observations of bicycling children were made at randomly selected observational sites 2 to 5 months after the intervention to assess changes in behavior. Helmet use at all observation sites tripled from 3.4% (1990, preintervention) to 16% (1991, postintervention). In the high-income intervention area, observed helmet use rose dramatically from 4% to 36% in contrast to the more modest increase in the high-income control area from 4% to 15%. In the low-income intervention area, there was a modest increase from 1% to 7%, but it did not differ from the increase in the low-income control area from 3% to 13%. The program was highly successful in children of high-income families but not in children of low-income families. Developing strategies for low-income families remains a priority.

    We examined the efficacy of praziquantel against Schistosoma haematobium among primary school children during a school-based deworming programme in the Burma Valley commercial farming area and the Nyamaropa rural areas in Zimbabwe, where the disease is highly endemic. Among 767 individuals infected with S. haematobium, 675 (88.0%) received treatment. Two single oral doses of 40mg/kg praziquantel were given 6 weeks apart. Of the 675 participants, heavy infection intensity was more common in males than females (chi(2)=6.61, P=0.010). Six weeks later, 624 participants (92.4%) were successfully followed up. The overall cure rate was 88.5% and the egg reduction rate was 98.2%. The highest cure rate was among those individuals with light infection. Seventy-two individuals remained infected at 6 weeks post treatment, among which 3 and 69 individuals had heavy and light infection, respectively. Forty-six of these children resolved following a second round of treatment at 6 weeks follow-up. Of the remaining children successfully followed-up, 22 resolved after a third round of treatment 6 months later. A wide range of observed mild and transient side effects were not associated with egg intensity. The parasitological cure rate was not associated with gender or age. Our study demonstrates that praziquantel is efficacious against S. haematobium in Zimbabwe, although low levels of persistent infection warrant further investigation.

    Background. To evaluate the efficacy and acceptability of orthokeratology for slowing myopic progression in children with a well conducted evidence-based analysis. Design. Meta-analysis. Participants. Children from previously reported comparative studies were treated by orthokeratology versus control. Methods. A systematic literature retrieval was conducted in MEDLINE, EMBASE, Cochrane Library, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. The included studies were subjected to meta-analysis using Stata version 10.1. Main Outcome Measures. Axial length change (efficacy) and dropout rates (acceptability) during 2-year follow-up. Results. Eight studies involving 769 subjects were included. At 2-year follow-up, a statistically significant difference was observed in axial length change between the orthokeratology and control groups, with a weighted mean difference (WMD) of −0.25 mm (95% CI, −0.30 to −0.21). The pooled myopic control rate declined with time, with 55, 51, 51, and 41% obtained after 6, 12, 18, and 24 months of treatment, respectively. No statistically significant difference was obtained for dropout rates between the orthokeratology and control groups at 2-year follow-up (OR, 0.79; 95% CI, 0.52 to 1.22). Conclusions. Orthokeratology is effective and acceptable for slowing myopic progression in children with careful education and monitoring. PMID:26221539

    Immunotherapy of brain tumors involves the stimulation of an antitumor immune response. This type of therapy can be targeted specifically to tumor cells thus sparing surrounding normal brain. Due to the presence of the blood-brain barrier, the brain is relatively isolated from the systemic circulation and, as such, the initiation of significant immune responses is more limited than other types of cancers. The purpose of this study was to show that the efficacy of tumor primed antigen presenting macrophage vaccines could be increased by: (1) PDT of the priming tumor cells, and (2) injection of allogeneic glioma cells directly into brain tumors. Experiments were conducted in an in vivo brain tumor model using Fisher rats and BT4C (allogeneic) and F98 (syngeneic) glioma cells. Preliminary results showed that vaccination alone had significantly less inhibitory effect on F98 tumor growth compared to the combination of vaccination and allogeneic cell (BT4C) injection.

    Previous functional magnetic resonance imaging (fMRI) studies investigating hemispheric dominance for language have shown that hemispheric specialization increases with age. We employed magnetoencephalography (MEG) to investigate these effects as a function of normal development. In sum, 22 healthy children aged 7-16 years were investigated using two language tasks: a verb-generation (VG) task and a vowel-identification (VI) task. Significant hemispheric differences were found for both tasks in cerebral language areas using oscillatory MEG spectral analyses, confirming the MEG's ability to detect hemispheric specialization for language in children. Additionally, a significant increase of this lateralization as a function of age was observed for both tasks. As performance in the VI task showed no correlation with age, this increase seems to be unrelated to performance. These results confirm an increase in hemispheric specialization as a function of normal brain maturation.

    The timing, intensity, and duration of exposure to both artificial and natural light have acute metabolic and physiological effects in mammals. Recent research in human adults suggests exposure to moderate intensity light later in the day is concurrently associated with increased body mass; however, no studies have investigated the effect of light exposure on body mass in young children. We examined objectively measured light exposure and body mass of 48 preschool-aged children at baseline, and measured their body mass again 12 months later. At baseline, moderate intensity light exposure earlier in the day was associated with increased body mass index (BMI). Increased duration of light exposure at baseline predicted increased BMI 12-months later, even after controlling for baseline sleep duration, sleep timing, BMI, and activity. The findings identify that light exposure may be a contributor to the obesogenic environment during early childhood. PMID:26735299

  4. The P7C3 class of neuroprotective compounds exerts antidepressant efficacy in mice by increasing hippocampal neurogenesis.

    Augmenting hippocampal neurogenesis represents a potential new strategy for treating depression. Here we test this possibility by comparing hippocampal neurogenesis in depression-prone ghrelin receptor (Ghsr)-null mice to that in wild-type littermates and by determining the antidepressant efficacy of the P7C3 class of neuroprotective compounds. Exposure of Ghsr-null mice to chronic social defeat stress (CSDS) elicits more severe depressive-like behavior than in CSDS-exposed wild-type littermates, and exposure of Ghsr-null mice to 60% caloric restriction fails to elicit antidepressant-like behavior. CSDS resulted in more severely reduced cell proliferation and survival in the ventral dentate gyrus (DG) subgranular zone of Ghsr-null mice than in that of wild-type littermates. Also, caloric restriction increased apoptosis of DG subgranular zone cells in Ghsr-null mice, although it had the opposite effect in wild-type littermates. Systemic treatment with P7C3 during CSDS increased survival of proliferating DG cells, which ultimately developed into mature (NeuN+) neurons. Notably, P7C3 exerted a potent antidepressant-like effect in Ghsr-null mice exposed to either CSDS or caloric restriction, while the more highly active analog P7C3-A20 also exerted an antidepressant-like effect in wild-type littermates. Focal ablation of hippocampal stem cells with radiation eliminated this antidepressant effect, further attributing the P7C3 class antidepressant effect to its neuroprotective properties and resultant augmentation of hippocampal neurogenesis. Finally, P7C3-A20 demonstrated greater proneurogenic efficacy than a wide spectrum of currently marketed antidepressant drugs. Taken together, our data confirm the role of aberrant hippocampal neurogenesis in the etiology of depression and suggest that the neuroprotective P7C3-compounds represent a novel strategy for treating patients with this disease.

    An increased echogenicity of the pancreas ("white pancreas") was sonographically found in 25 children with various pancreatic and systemic diseases. Fifteen patients with cystic fibrosis had a small white pancreas. Five patients with haemosiderosis, two with pancreatitis and one with Shwachman-syndrome presented with a normal-sized or slightly enlarged pancreas. Fatty infiltration and calcifications of the pancreas can also increase its echogenicity.

    An increasing number of children now undergo magnetic resonance imaging (MRI) under sedation. MRI requires a cool environment. Because children have a larger surface area to body weight ratio than adults and because active warming devices are not MRI compatible, hypothermia as a result of passive heat loss is a risk. Absorption of radiofrequency radiation generated by the scanning process, however, may partially offset this heat loss. To determine the effect of absorbed radiofrequency radiation on body temperature during MRI, we measured pre-MRI and post-MRI tympanic temperatures in 30 children who underwent brain MRI while sedated with chloral hydrate and covered with a hospital gown and blanket. The mean (+/- sd) age was 14.9 +/- 8.6 mo, and weight was 9.8 +/- 2.8 kg. During an average scan duration of 42 +/- 13 min, mean tympanic temperatures increased 0.5 degrees C from 36.9 degrees C +/- 0.4 degrees C to 37.4 degrees C +/- 0.3 degrees C; (95% CI difference, 0.3 degrees C to 0.7 degrees C; P < 0.001). Our findings suggest that children sedated with chloral hydrate for brain MRI did not become hypothermic but rather had increased body temperature despite minimal barriers to heat loss and no active warming. These results imply that aggressive measures to prevent passive heat loss during MRI studies may not be needed in all patients.

  7. Has blood pressure increased in children in response to the obesity epidemic?

    The associations between elevated blood pressure and overweight, on one hand, and the increasing prevalence over time of pediatric overweight, on the other hand, suggest that the prevalence of elevated blood pressure could have increased in children over the last few decades. In this article we review the epidemiologic evidence available on the prevalence of elevated blood pressure in children and trends over time. On the basis of the few large population-based surveys available, the prevalence of elevated blood pressure is fairly high in several populations, whereas there is little direct evidence that blood pressure has increased during the past few decades despite the concomitant epidemic of pediatric overweight. However, a definite conclusion cannot be drawn yet because of the paucity of epidemiologic studies that have assessed blood pressure trends in the same populations and the lack of standardized methods used for the measurement of blood pressure and the definition of elevated blood pressure in children. Additional studies should examine if favorable secular trends in other determinants of blood pressure (eg, dietary factors, birth weight, etc) may have attenuated the apparently limited impact of the epidemic of overweight on blood pressure in children.

    People can get most of their needs broadly satisfied in two ways: by close communal ties and by dealings with people in the marketplace. These modes of relating-termed communal and market-often necessitate qualitatively different motives, behaviors, and mind-sets. We reasoned that activating market mode would produce behaviors consistent with it and impair behaviors consistent with communal mode. In a series of experiments, money-the market-mode cue-was presented to Polish children ages 3 to 6. We measured communal behavior by prosocial helpfulness and generosity and measured market behavior by performance and effort. Results showed that handling money (compared with other objects) increased laborious effort and reduced helpfulness and generosity. The effects of money primes were not due to the children's mood, liking for money, or task engagement. This work is the first to demonstrate that young children tacitly understand market mode and also understand that money is a cue to shift into it.

    1988-11-01

    A battery of neurobehavioral examinations was carried out on 30 children who were 6-11 yr of age and who had resided near a lead smelter all their lives. Their blood lead levels were 35-60 micrograms/100 ml and erythrocyte protoporphyrin levels were greater than 100 micrograms/100 ml. Neurological examination revealed that they had a significantly higher incidence of pathological findings (e.g., muscle hypotonia, increased tendon reflexes, dysarthria, and dysdiadochokinesia) than children from an unpolluted area who were matched for age, sex, family size, and educational and socioeconomic status of the parents, but who had normal erythrocyte protoporphyrin levels. The children with elevated blood lead levels showed, after assessment by the Oseretsky test, retardation of motor maturation; they also scored higher on the minimal brain damage scale of the Rutter behavioral questionnaire. These differences persisted at a 4-yr follow-up, and their school performance was consistently poorer than that of the controls.

    The study aims to observe the clinical efficacy of Baoerkang san on spleen-deficiency and dampness-obstructing diarrhea in children. Children diarrhea divided into acute diarrhea (group I) and chronic persistent diarrhea (group II). A randomized, double-blind, positive control test was conducted for dose finding. The 340 cases with acute diarrhea in group I were divided into three groups: the high dose group (112 patients), the low dose group (113 patients) and the positive control group (115 patients), which were treated for 3 days. Their clinical efficacies were compared to evaluate the clinical safety of Baoerkang san. The 167 patients with chronic persistent diarrhea in group If were divided into the high dose group (56 patients), the low dose group (55 patients) and the control group (56 patients), which were treated for 5 days. Their clinical efficacy were compared to evaluate the clinical safety of Baoerkang san. According to the results, the cure rate and the effective rate of acute diarrhea and chronic persistent diarrhea in the high dose group and the low dose group were significantly higher than that of the positive control group (P <0. 05, P < 0.01). In the treatment of spleen-deficiency and dampness-obstructing diarrhea with traditional Chinese medicines, the cure rate and the effective rate of acute diarrhea and chronic persistent diarrhea in the high dose group and the low dose group were significantly higher than that of the positive control group (P < 0.05, P < 0.01). During the test, all of the three groups did not suffer any adverse event, with no any abnormality in general physical indexes. In conclusion, Baoerkang san shows a significant efficacy in treating acute diarrhea and chronic persistent diarrhea (spleen-deficiency and dampness-obstructing) and safe clinical application.

    We examined the creation of spontaneous and suggestion-induced false memories in maltreated and non-maltreated children. Maltreated and non-maltreated children were involved in a Deese-Roediger-McDermott false memory paradigm where they studied and remembered negative and neutral word lists. Suggestion-induced false memories were created using a misinformation procedure during which both maltreated and non-maltreated children viewed a negative video (i.e., bank robbery) and later received suggestive misinformation concerning the event. Our results showed that maltreated children had higher levels of spontaneous negative false memories but lower levels of suggestion-induced false memories as compared to non-maltreated children. Collectively, our study demonstrates that maltreatment both increases and decreases susceptibility to memory illusions depending on the type of false memory being induced. Statement of contribution What is already known on this subject? Trauma affects memory. It is unclear how trauma affects false memory. What does this study add? This study focuses on two types of false memories.

    The impact of music on human cognition has a distinguished history as a research topic in psychology. The focus of the present study was on investigating the effects of music instruction on the cognitive development of preschool children. From a sample of 154 preschool children of Tehran kindergartens, 60 children aged between 5 and 6 were randomly assigned to two groups, one receiving music lessons and the other (matched for sex, age and mother's educational level) not taking part in any music classes. Children were tested before the start of the course of music lessons and at its end with 4 subtests of the Tehran-Stanford-Binet Intelligence Scale (TSB). The experimental group participated in twelve 75-min weekly music lessons. Statistical analysis showed significant IQ increase in participants receiving music lessons, specifically on the TSB verbal reasoning and short-term memory subtests. The numerical and visual/abstract reasoning abilities did not differ for the two groups after lessons. These data support studies that found similar skills enhancements in preschool children, despite vast differences in the setting in which the instruction occurred. These findings appear to be consistent with some neuroimaging and neurological observations which are discussed in the paper.

    Background Children with severe asthma have persistent symptoms despite treatment with inhaled corticosteroids (ICSs). The differentiating features of severe asthma in children are poorly defined. Objective To identify features of severe versus mild-to-moderate asthma in school-age children using noninvasive assessments of lung function, atopy, and airway inflammation. Methods A total of 75 children (median age, 10 years) with asthma underwent baseline characterization including spirometry and lung volume testing, methacholine bronchoprovocation, allergy evaluation, and offline measurement of exhaled nitric oxide (FENO). Twenty-eight were followed longitudinally over 6 months. Participants were assigned to the severe asthma subgroup if they required high-dose ICS plus 2 or more minor criteria. Results Children with severe versus mild-to-moderate asthma had more symptoms, greater airway obstruction, more gas trapping, and increased bronchial responsiveness to methacholine. Subjects with severe asthma also had higher concentrations of FENO and significantly greater sensitization to aeroallergens. With long-term study, both the reduction in FEV1 and increase in FENO persisted in the severe versus mild-to-moderate group. Furthermore, despite adjustments in ICS doses, the frequency of exacerbations was significantly higher in subjects with severe (83%) versus mild-to-moderate asthma (43%). Conclusion Severe asthma in childhood is characterized by poor symptom control despite high-dose ICS treatment and can be differentiated from mild-to-moderate asthma by measurement of lung function and FENO. Clinical implications Clinicians should suspect severe asthma in children with poor response to ICS, airway obstruction, and high FENO. PMID:17157650

    This paper makes a case for research on community interventions on child rearing. Sufficient evidence has accumulated about the development of children's problem behavior to justify evaluating efforts to reduce the prevalence of these problems in whole communities. The contextual risk factors for diverse child behavior problems are well understood, and interventions to ameliorate individual risk factors have been developed and evaluated. Because interventions with individual children have proven to be efficacious, it is now appropriate to direct energy toward reducing the prevalence of children with behavior problems. At the same time, existing interventions have limitations. Community interventions may be needed to modify the larger social context for families. This paper enumerates possible components of a community intervention to improve child-rearing outcomes. Existing evidence indicates that communities would benefit from making parent training and family support programs available to parents. Validated methods of identifying and remediating academic and behavioral problems in schools are available, but influencing schools to adopt them remains a problem. Community organizing could mobilize communities to allocate the resources necessary to support such parenting and schooling programs as well as encourage their adoption. Media campaigns could foster community support and directly influence parenting practices. Efforts to modify peer influences to use illicit substances have received empirical support; similar efforts may be relevant to preventing other problems. The development of a science of community interventions on child rearing is hampered by overreliance on randomized control trials. For this reason, two examples of time-series experimental evaluations of community intervention components are described here. PMID:22478196

    This study was conducted to provide an insight into the effect of Se (through soil) induced changes in Brassica juncea plants in the presence and absence of 24-epibrassinolide (EBL; foliar). The Se treatments showed dual response, 10 μM of Se significantly increased growth, water relations, photosynthetic attributes along with carbonic anhydrase activity whereas its higher concentrations proved inhibitory in concentration dependent manner. The follow-up application of EBL to the Se stressed plants improved growth, water relations, photosynthesis and simultaneously enhanced the various antioxidant enzymes viz. catalase, peroxidase and superoxide dismutase with the excess accumulation of proline. In addition to this, 10 μM Se increases the efficacy of 10(-8) M of EBL and both in combination showed maximum increase for the growth and photosynthetic traits of plants. On the other hand, the elevated level of antioxidant enzymes as well as proline could have conferred tolerance to the Se-stressed plants resulting in improved growth, water relations and photosynthesis.

    Two children with autism were taught to engage in a variety of complex social behaviors using peer-implemented pivotal response training (PRT), a set of procedures designed to increase motivation and promote generalization. Typical peers were taught to implement PRT strategies by modeling, role playing, and didactic instruction. After training, peers implemented the procedures in the absence of direct supervision in a classroom environment. After the intervention, both children with autism maintained prolonged interactions with the peer, initiated play and conversations, and increased engagement in language and joint attention behaviors. In addition, teachers reported positive changes in social behavior, with the largest increases in peer-preferred social behavior. Further, these effects showed generality and maintenance. Implications of these findings are discussed. PMID:7592145

    Purpose: ZD6126 is a vascular-targeting agent that induces selective effects on the morphology of proliferating and immature endothelial cells by disrupting the tubulin cytoskeleton. The efficacy of ZD6126 was investigated in large vs. small tumors in a variety of animal models. Methods and Materials: Three rodent tumor models (KHT, SCCVII, RIF-1) and three human tumor xenografts (Caki-1, KSY-1, SKBR3) were used. Mice bearing leg tumors ranging in size from 0.1-2.0 g were injected intraperitoneally with a single 150 mg/kg dose of ZD6126. The response was assessed by morphologic and morphometric means as well as an in vivo to in vitro clonogenic cell survival assay. To examine the impact of tumor size on the extent of enhancement of radiation efficacy by ZD6126, KHT sarcomas of three different sizes were irradiated locally with a range of radiation doses, and cell survival was determined. Results: All rodent tumors and human tumor xenografts evaluated showed a strong correlation between increasing tumor size and treatment effect as determined by clonogenic cell survival. Detailed evaluation of KHT sarcomas treated with ZD6126 showed a reduction in patent tumor blood vessels that was {approx}20% in small (<0.3 g) vs. >90% in large (>1.0 g) tumors. Histologic assessment revealed that the extent of tumor necrosis after ZD6126 treatment, although minimal in small KHT sarcomas, became more extensive with increasing tumor size. Clonogenic cell survival after ZD6126 exposure showed a decrease in tumor surviving fraction from approximately 3 x 10{sup -1} to 1 x 10{sup -4} with increasing tumor size. When combined with radiotherapy, ZD6126 treatment resulted in little enhancement of the antitumor effect of radiation in small (<0.3 g) tumors but marked increases in cell kill in tumors larger than 1.0 g. Conclusions: Because bulky neoplastic disease is typically the most difficult to manage, the present findings provide further support for the continued development of vascular

    In three studies, two-year-old children communicated to a parent which of two out-of-reach objects contained a sticker. Across trials, the objects were positioned in different configurations so that it was possible or impossible for a child's pointing gesture to unambiguously specify one object. In Study 1, the objects used were two boxes distinguished by a different picture of a vehicle on the front, and children (n = 16; mean age 2;8) were significantly more likely to name the box's picture on trials where pointing alone could not unambiguously specify the box than on trials where it could. In Studies 2 and 3, the stickers were hidden inside different animal figures. Older two-year-olds (n = 16, mean age 2;9), but not younger two-year-olds (n = 16, mean age 2;4), showed an ability to recognize the referential (in)efficacy of their pointing gestures and to adapt their communication accordingly.

    Bell's palsy is the most common cause of acute peripheral facial nerve paralysis, but the optimal dose of corticosteroids in pediatric patients is still unclear. This retrospective study aimed to evaluate the efficacy of low-dose corticosteroid therapy compared with high-dose corticosteroid therapy in children with Bell's palsy. Patients were divided into 2 groups based on the dose of oral prednisolone regimen initiated. The severity of idiopathic facial nerve paralysis was graded according to the House-Brackmann Grading Scale. The patients were re-assessed in terms of recovery rate at the first, third, and sixth months of treatment. There was no significant difference in complete recovery between the 2 groups after 1, 3, and 6 months of treatment. In our study, we concluded that even at a dose of 1 mg/kg/d, oral prednisolone was highly effective in the treatment of Bell's palsy in children.

    Narratives, also called stories, can be found in conversations, children's play interactions, reading material, and television programs. From infancy to adulthood, narrative comprehension processes interpret events and inform our understanding of physical and social environments. These processes have been extensively studied to ascertain the multifaceted nature of narrative comprehension. From this research we know that three overlapping processes (i.e., knowledge integration, goal structure understanding, and causal inference generation) proposed by the constructionist paradigm are necessary for narrative comprehension, narrative comprehension has a predictive relationship with children's later reading performance, and comprehension processes are generalizable to other contexts. Much of the previous research has emphasized internal and predictive validity; thus, limiting the generalizability of previous findings. We are concerned these limitations may be excluding underrepresented populations from benefits and implications identified by early comprehension processes research. This review identifies gaps in extant literature regarding external validity and argues for increased emphasis on externally valid research. We highlight limited research on narrative comprehension processes in children from low-income and minority populations, and argue for changes in comprehension assessments. Specifically, we argue both on- and off-line assessments should be used across various narrative types (e.g., picture books, televised narratives) with traditionally underserved and underrepresented populations. We propose increasing the generalizability of narrative comprehension processes research can inform persistent reading achievement gaps, and have practical implications for how children learn from narratives.

    This study examined the feasibility and potential efficacy of the family-centered Prevent-Teach-Reinforce (PTR) model with three families of young children with an autism spectrum disorder or language delay with sensory processing problems. Particularly, the study assessed the family adherence to the PTR intervention, changes in child behavior, family use of the Individualized Behavior Rating Scale Tool (IBRST), procedural integrity, and social validity. A multiple-baseline design across families was used to examine the functional relation between parent-implemented PTR intervention and changes in child behavior. Results indicated that the family-centered PTR process was successful in promoting parents to design and implement the PTR intervention plans with fidelity, and the parents' implemented intervention plans were effective in increasing replacement behavior and decreasing problem behavior across children. The results also indicated that the parents successfully used the IBRST to monitor their child's progress and were highly satisfied with the PTR intervention process and outcomes for their children.

    Metronidazole is frequently used against Giardia infection; however, it has been associated with significant failure rates in clearing parasites from the gut; additionally, as it should be taken for 5 to 10 days, it is associated with poor compliance, probably due to side effects. Other drugs, including tinidazole (TNZ) and albendazole (ABZ) have been included in the antigiardial armamentarium. Our aim was to assess the efficacy of ABZ compared with TNZ in Giardia infections in children. A systematic review and a meta-analysis were carried out. PubMed, Medline, EMBASE, CENTRAL, and LILACS were searched electronically until February 2015. Also relevant journals and references of studies included therein were hand-searched for randomised controlled trials (RCTs). The meta-analysis was limited to RCTs evaluating the use of ABZ compared with TNZ in children with Giardia infection. The assessed outcome was parasitological efficacy. Prediction intervals (PI) were computed to better express uncertainties in the effect estimates. Five RCTs including 403 children were included. Overall, TNZ significantly outperformed ABZ without differences between subgroups defined by ABZ dosages [relative risk, (RR) 1.61 (95% CI): (1.40-1.85); P<0.0001]. The 95% prediction interval range is 1.28-2.02. There was no significant heterogeneity (I(2)=0%; Q-test of heterogeneity P=0.4507. The number-needed-to-treat, the average number of patients who need to be treated with TNZ to gain one additional good outcome as compared with ABZ was 4, 95% CI: 3-5. Our results show that TNZ outperforms ABZ in the treatment of Giardia infections in children from developing countries.

    Despite the intent of integration to promote positive social interactions between children with and without disabilities, there is growing concern that many children with special needs who are in inclusive settings feel socially isolated. The evaluation of interventions designed to promote disability awareness is critical if we are to increase opportunities for social success for these children. This research study was designed to determine whether the Kids Are Kids (KAK) program can positively impact the attitudes of children toward their peers with physical disabilities, as well as increase the social inclusion of these children. Results suggest that the KAK program had a positive impact on the attitudes of children toward their peers with disabilities, immediately following the program. Where social skill building was provided to 1 target child, attitude scores for that class remained elevated 1 month after the program. Two of the 3 target children reported increased social inclusion 1 month after the program.

    The purpose of this study was to examine the role of family cohesion, adaptability, and paternal self-efficacy in psychological well-being of fathers of children with and without disabilities and whether the effects of these variables on psychological well-being were the same for both groups of fathers. In addition, the potential differences in perceived well-being between the two groups of fathers were examined. Sixty-three fathers of children with disabilities and 217 fathers of typically developing children participated in this study. Fathers of children with disabilities scored significantly higher on the self-acceptance dimension of psychological well-being compared with fathers of children without disabilities. After controlling for the demographic factors, family cohesion and paternal self-efficacy significantly and positively predicted well-being of fathers; the effects of these variables on well-being were the same for both groups of fathers.

    The manner in which teachers mediate children's learning varies across early childhood classrooms. In this study, we used a multielement design to evaluate the efficacy of three commonly implemented strategies that varied in teacher directedness for teaching color- and object-name relations. Strategy 1 consisted of brief exposure to the target relations followed by an exclusively child-led play period in which correct responses were praised. Strategy 2 was similar except that teachers prompted the children to vocalize relations and corrected errors via model prompts. Strategy 3 incorporated the same procedures as Strategy 2 except that a brief period of teacher-initiated trials was arranged; these trials involved the use of prompt delay between questions and prompts, and correct responses resulted in tokens and back-up activity reinforcers. Children's preferences for the different teaching strategies were also directly assessed. Strategy 3 was most effective in promoting the acquisition and generalization of the color- and object-name relations and was also most preferred by the majority of children, Strategy 1 was the least effective, and Strategy 2 was typically the least preferred. Implications for the design of early educational environments based on evidence-based values are discussed.

    The US Food Security Scale (USFSS) measures household and child food insecurity (CFI) separately. Our goal was to determine whether CFI increases risks posed by household food insecurity (HFI) to child health and whether the Food Stamp Program (FSP) modifies these effects. From 1998 to 2004, 17,158 caregivers of children ages 36 mo were interviewed in six urban medical centers. Interviews included demographics, the USFSS, child health status, and hospitalization history. Ten percent reported HFI, 12% HFI and CFI (H&CFI). Compared with food-secure children, those with HFI had significantly greater adjusted odds of fair/poor health and being hospitalized since birth, and those with H&CFI had even greater adverse effects. Participation in the FSP modified the effects of FI on child health status and hospitalizations, reducing, but not eliminating, them. Children in FSP-participating households that were HFI had lower adjusted odds of fair/poor health [1.37 (95% CI, 1.06-1.77)] than children in similar non-FSP households [1.61 (95% CI, 1.31-1.98)]. Children in FSP-participating households that were H&CFI also had lower adjusted odds of fair/poor health [1.72 (95% CI, 1.34-2.21)] than in similar non-FSP households [2.14 (95% CI, 1.81-2.54)]. HFI is positively associated with fair/poor health and hospitalizations in young children. With H&CFI, odds of fair/poor health and hospitalizations are even greater. Participation in FSP reduces, but does not eliminate, effects of FI on fair/poor health.

    Fathers' postnatal distress has been associated with subsequent emotional and behavioral problems for children; however, the mechanisms by which this occurs have received less attention. One potential pathway could be via the negative effects that father mental health problems and parenting self-efficacy (PSE) in the postnatal period have on later parenting behaviors. Using a nationally representative cohort of Australian father-child dyads (N = 3,741), the long-term relationships between fathers' psychological distress and PSE in the postnatal period, parenting behavior when children were aged 4-5 years, and emotional-behavioral outcomes for children aged 8-9 years were explored. Path analysis indicated that high distress and low PSE in the postnatal period was associated with higher levels of hostile parenting and lower parenting consistency when children were aged 4-5 years; in turn, these were associated with poorer child outcomes at 8-9 years. These results remained significant after controlling for socioeconomic position, couple relationship quality, mothers' and fathers' mental health, and fathers' concurrent parenting behavior. The pathways among PSE, parenting hostility, parenting consistency, and children's outcomes at age 8-9 years differed for fathers of boys compared with fathers of girls. Results highlight the importance of father-inclusive assessments of postnatal mental health. Support programs targeting new fathers' perceptions of parenting competence may be particularly important for fathers experiencing postnatal distress. For fathers, building a stronger sense of parenting competence in the postnatal period is important for later parenting behavior, which relates to children's emotional and behavioral outcomes during middle childhood.

  9. Grafting Aptamers onto Gold Nanostars Increases in Vitro Efficacy in a Wide Range of Cancer Cell Types

    PubMed Central

    2015-01-01

    We report the design of a nanoconstruct that can function as a cell-type independent agent by targeting the ubiquitous protein nucleolin. Gold nanostars (AuNS) loaded with high densities of nucleolin-specific DNA aptamer AS1411 (Apt-AuNS) produced anticancer effects in a panel of 12 cancer lines containing four representative subcategories. We found that the nanoconstructs could be internalized by cancer cells and trafficked to perinuclear regions. Apt-AuNS resulted in downregulation of antiapoptotic Bcl-2 mRNA expression by ca. 200% compared to cells without the nanoconstructs. The caspase 3/7 activity (apoptosis) and cell death in cancer cells treated with Apt-AuNS increased by 1.5 times and by ca. 17%, respectively, compared to cells treated with free AS1411 at over 10 times the concentration. Moreover, light-triggered release of aptamer from the AuNS further enhanced the in vitro efficacy of the nanoconstructs in the cancer line panel with a 2-fold increase in caspase activity and a 40% decrease in cell viability compared to treatment with Apt-AuNS only. In contrast, treatments of the nanoconstructs with or without light-triggered release on a panel of normal cell lines had no adverse effects. PMID:24422969

    Caring for a person with a mental illness can have adverse effects on caregivers; however, little is known about how best to help such caregivers. The aim of the present study was to examine the efficacy of a cognitive behaviour therapy-guided self-help manual in increasing resilience in caregivers of individuals with depression, in comparison to caregivers who receive routine support only. A randomized, controlled trial was conducted, following CONSORT guidelines, with 54 caregivers allocated to parallel intervention (self-help manual) (n = 27) or control (standard support) (n = 27) groups. Resilience was assessed at baseline, post-test (week 8), and follow up (week 12). Intention-to-treat analyses were undertaken. Repeated-measures ANOVA indicated a significant difference in resilience scores between the three time points, showing a large effect. Pairwise comparisons between intervention and control groups indicated resilience to be significantly different between baseline and post-test, and between baseline and follow up, but not between post-test and follow up. Overall, the intervention group showed a slightly greater increase in resilience over time than the control group; however, the time-group interaction was not significant. Guided self-help is helpful in improving caregivers' resilience and could be used as an adjunct to the limited support provided to carers by mental health nurses and other clinicians.

    Microtubules are the fundamental components in mitotic spindle, which plays essential roles in cell division. It was well known that purified microtubules could be affected by static magnetic fields (SMFs) in vitro because of the diamagnetic anisotropy of tubulin. However, whether these effects lead to cell division defects was unknown. Here we find that 1T SMFs induce abnormal mitotic spindles and increase mitotic index. Synchronization experiments show that SMFs delay cell exit from mitosis and cause mitotic arrest. These mimic the cellular effects of a microtubule-targeting drug Paclitaxel (Taxol), which is frequently used in combination with 5-Fluorouracil (5-FU) and Cisplatin in cancer treatment. Using four different human cancer cell lines, HeLa, HCT116, CNE-2Z and MCF7, we find that SMFs increase the antitumor efficacy of 5-FU or 5-FU/Taxol, but not Cisplatin, which indicates that the SMF-induced combinational effects with chemodrugs are drug-specific. Our study not only reveals the effect of SMFs on microtubules to cause abnormal mitotic spindles and delay cells exit from mitosis, but also implies the potential applications of SMFs in combination with chemotherapy drugs 5-FU or 5-FU/Taxol, but not with Cisplatin in cancer treatment.

    Background and Aims Pediatric use of liver transient elastography (TE) is attractive for its non-invasiveness, but reference values have not been established. We aimed to determine reference values for TE in children. Methods In pediatric patients (1 to 18 years), TE (FibroScan®) with an M probe was used for both liver stiffness measurement (LSM) and measurement of hepatic fat deposition by using a controlled attenuation parameter (CAP). The patients were divided into three relevant age groups: preschoolers (1 to 5 years), elementary school children (6 to 11 years), and adolescents (12 to 18 years). Overweight or obese patients or those with known liver disease, elevated serum liver enzymes, or hepatic echogenic abnormality were excluded from the study. Results Among 139 children, 123 (88.5%; 62 male; median age, 11.7 years; age range, 1.3 to 17.2 years) were successfully subjected to M-probe TE without anesthesia. Median LSM increased with age: it was 3.4 kPa (2.3 to 4.6 kPa, 5th to 95th percentiles) at ages 1 to 5 years; 3.8 (2.5 to 6.1) kPa at ages 6 to 11; and 4.1 (3.3 to 7.9) kPa at ages 12 to 18 (P = 0.001). Median CAP was not age dependent: it was 183 (112 to 242) for ages 1 to 18 years. Conclusions M-probe TE is suitable in a wide age range of children from age 1 year up. In children without evidence of liver disease, LSM has an age-dependent increase, whereas CAP does not differ between ages 1 and 18. PMID:27861607

    We tested the effectiveness of a tablet application and differential reinforcement to increase eye contact in 3 children with autism. The application required the child to look at a picture of a person's face and identify the number displayed in the person's eyes. Eye contact was assessed immediately after training, 1 hr after training, and in a playroom. The tablet application was not effective; however, differential reinforcement was effective for all participants.

    There is scarce information regarding the concentration of cytokines in cerebrospinal fluid (CSF) of children with acute lymphoblastic leukemia (ALL) and their clinical association with CNS status. A prospective analysis of 40 patients <18years with newly diagnosed ALL was performed. Human cytokine magnetic bead panel assay values of IL-2, IL-4, IL-6, IL-8, IL-10, MCP-1, TNF-α in CSF at diagnosis, end of induction to remission, and 6months after diagnosis were determined. IL-6 and MCP-1 values showed a significant increment at the end of induction. From the whole group 4 (10.0%), patients relapsed to the CNS at a median of 11.48months. A significantly higher value of TNF-α at third determination in these CNS-relapsed patients was documented, 7.48 vs. 2.86pg/mL in 36 children without relapse (p=0.024). TNF-α concentration increased at a median 5.48months before CNS relapse. By receiver-operating characteristic curve (ROC) analysis, the best cut-off point of TNF-α concentration that better predicted CNS relapse was ≥1.79pg/mL. In conclusion an increase in TNF-α concentration on CSF preceded CNS relapse in children with ALL. An increase in MCP-1 and IL-6 was not associated to CNS relapse and appears to result from an inflammatory response after IT injection of chemotherapy.

    2006-01-01

    We evaluated the effectiveness of a dentist-implemented behavioral intervention in which brief escape from dental treatment was provided on a regular basis, independent of the child's behavior. Within a multiple baseline design across subjects, 5 children, ages 4 to 7 years, were provided with temporary escape from dental treatment on a fixed-time schedule. The intervals were signaled by an electronic timer worn by the dentist. Clinically significant reductions were observed in physically disruptive behavior across all 5 children with the introduction of noncontingent escape, and verbally disruptive behavior was markedly reduced in 4 of the 5 children. In addition, the dental staff's use of physical restraint was reduced to near zero across all 5 children. The research extends the literature in both clinical dentistry and in applied behavior analysis by demonstrating that a dentist can easily and effectively implement noncontingent reinforcement to produce clinically significant and socially important changes in children's health behavior.

    As the efficacy of combined nebulized salbutamol & ipratropium bromide as well as L-adrenaline to treat acute bronchiolitis is not well studied among the Bangladeshi infants, this study was carried out to see their efficacy in acute bronchiolitis and to compare their effectiveness. This randomized clinical trial was done among 60 children aged less than 02 years, admitted in the department of Pediatrics, Dhaka Medical College Hospital, during January through December 2005 with acute bronchiolitis. After a quick initial assessment, nebulization were done twice at 6 hours interval with the mentioned drugs, group wise (one group with salbutamol plus ipratropium bromide and other group with L-adrenaline alone) and the outcomes were assessed after 30 minutes of each nebulization in respect to oxygen saturation and clinical modified respiratory distress assessment instrument (MRDAI) scores. The results were analyzed by using SPSS version 10.0 and at a p value of children in both the groups, compared to their baseline status (p=0.000). However, L-adrenaline showed more efficacy (MRDAI, p=0.021; SaO2, p=0.034) than combined Salbutamol & Ipratropium bromide. Both L-adrenaline and combined salbutamol & ipratropium bromide were found effective in acute bronchiolitis but L-adrenaline was found more effective. A large multi-centre clinical trial is recommended.

    Although accidental injury is the main factor involved in the death of young children in many countries, few studies have focused on parents' competence with regard to self-efficacy of first aid for their children following injuries occurring at home. The purpose of this cross-sectional study was to investigate parental self-sufficiency of first aid for home accidents in children aged 0-4 years. The study is a cross-sectional designed. Data from 445 parents recruited were collected by purposive sampling at eight metropolitan community health centers in central Taiwan. Measurements were taken from a self-developed questionnaire that included 37 questions. Logistic regression analysis was applied to explore the associations between factors and parents' self-efficacy of first aid at home accident. Our findings show that parents' overall rate of knowledge of first aid was 72%. The mean score for 100% certainty in parents' self-efficacy of first aid was 26.6%. The lowest scores for self-efficacy were with regard to choking and cardiopulmonary resuscitation (CPR). There was a significantly positive correlation between parents' knowledge and self-efficacy of first aid (p<0.01), and thus knowledge of first aid is a predictor of parents' self-efficacy. Knowledge of first aid is also a partly mediator between participants' attending first aid program, participants' first aid information obtained from health personnel and self-efficacy of first aid. Our findings suggest that medical services should provide first aid resources to help manage accidental injuries involving children, particularly information on how to deal with choking and CPR. With an appropriate program provided by health professionals, parents' self-efficacy of first aid for home accidents will be positively enhanced.

    Salmonella enterica is the leading cause of bloodstream infection in children in sub-Saharan Africa, but few data are available from Central-Africa. We documented during the period November 2011 to May 2012 an epidemic increase in invasive Salmonella bloodstream infections in HGR Bwamanda, a referral hospital in Equateur Province, DR Congo. Salmonella spp. represented 90.4 % (103 out of 114) of clinically significant blood culture isolates and comprised Salmonella Typhimurium (54.4 %, 56 out of 103), Salmonella Enteritidis (28.2 %, 29 out of 103) and Salmonella Typhi (17.5 %, 18 out of 103), with Salmonella Enteritidis accounting for most of the increase. Most (82 out of 103, 79.6 %) isolates were obtained from children < 5 years old. Median ages of patients infected with Salmonella Typhimurium and Salmonella Enteritidis were 14 months (14 days to 64 years) and 19 months (3 months to 8 years) respectively. Clinical presentation was non-specific; the in-hospital case fatality rate was 11.1 %. More than two thirds (69.7 %, 53 out of 76) of children < 5 years for whom laboratory data were available had Plasmodium falciparum infection. Most (83/85, 97.6 %) non-typhoid Salmonella isolates as well as 6/18 (33.3 %) Salmonella Typhi isolates were multidrug resistant (i.e. resistant to the first-line oral antibiotics amoxicillin, trimethoprim-sulfamethoxazole and chloramphenicol), one (1.0 %) Salmonella Typhimurium had decreased ciprofloxacin susceptibility owing to a point mutation in the gyrA gene (Gly81Cys). Multilocus variable-number tandem-repeat (MLVA) analysis of the Salmonella Enteritidis isolates revealed closely related patterns comprising three major and four minor profiles, with differences limited to one out of five loci. These data show an epidemic increase in clonally related multidrug-resistant Salmonella bloodstream infection in children in DR Congo.

Objectives In northern Ecuador, where floriculture is intensive and relies on female employment, we carried out an intensive cross-sectional study to assess children’s neurobehavioral functions at 6–8 years of age. Methods We examined all 87 children attending two grades in the local public school with an expanded battery of neurobehavioral tests. Information on pesticide exposure during the index pregnancy was obtained from maternal interview. The children’s current pesticide exposure was assessed from the urinary excretion of organophosphate metabolites and erythrocyte acetylcholine esterase activity. Results Of 84 eligible participants, 35 were exposed to pesticides during pregnancy via maternal occupational exposure, and 23 had indirect exposure from paternal work. Twenty-two children had detectable current exposure irrespective of their prenatal exposure status. Only children with prenatal exposure from maternal greenhouse work showed consistent deficits after covariate adjustment, which included stunting and socioeconomic variables. Exposure-related deficits were the strongest for motor speed (Finger Tapping Task), motor coordination (Santa Ana Form Board), visuospatial performance (Stanford-Binet Copying Test), and visual memory (Stanford-Binet Copying Recall Test). These associations corresponded to a developmental delay of 1.5–2 years. Prenatal pesticide exposure was also significantly associated with an average increase of 3.6 mmHg in systolic blood pressure and a slight decrease in body mass index of 1.1 kg/m2. Inclusion of the pilot data strengthened these results. Conclusions These findings support the notion that prenatal exposure to pesticides—at levels not producing adverse health outcomes in the mother

    Health literacy, the ability to acquire health-related knowledge and make appropriate health-related decisions, is regarded as a key barrier to meaningfully convey health information to children and can impact food choice. Emolabeling is an image-based labeling strategy aimed at addressing this problem by conveying health information using emotional correlates of health using emoticons (happy = healthy; sad = not healthy). To test the utility of such a method to promote healthy food choices among children, 64 children (59% girls, <5% non-White, mean BMI = 52nd percentile) in kindergarten through 5th grade were first given a brief 5-min lesson on how to use the emoticons, then asked to choose any 4 foods in each of 2 aisles structured to mimic a grocery aisle - there were 12 identical foods placed in the same location in each aisle with half being low calorie and half high calorie snacks. Foods were emolabeled in one aisle; no emolabels were used in the other aisle; the order that children were brought in each aisle was counterbalanced. Results showed that adding emolabels increased the number (M ± SD) of healthy foods chosen (3.6 ± 0.7 with vs. 2.3 ± 1.1 without emolabels present [95% CI 1.0, 1.5], R(2) = .67) and reduced the total calories (M ± SD) of foods chosen (193.5 ± 88.5 Cal with vs. 374.3 ± 152.6 Cal without emolabels present [95% CI -212.6, -149.0], R(2) = .70). Hence, adding emolabels was associated with healthier food choices among children, thereby demonstrating one possible strategy to effectively overcome health literacy barriers at these ages.

    Background Improving patient care for individuals with lung cancer is a priority due to the increasing burden of the disease globally. One way this can be done is by improving patient self-management capabilities through increasing their self-efficacy. This can improve positive outcomes for patients with chronic conditions and increase their ability to manage the challenges of such illnesses. Unfortunately, patients with chronic conditions often struggle to travel far from home to engage with patient education events, a common means of improving self-efficacy. The development of more accessible tools for improving patient self-efficacy is required to increase quality of life for patients with chronic conditions. Objective To evaluate the feasibility of delivering symptom identification and management information to patients with advanced lung cancer using an online program. Methods This article describes a pre-post test study to evaluate a Qstream online learning platform to improve patient self-efficacy for managing advanced lung cancer symptoms. Undertaking this program should increase participant knowledge about the side-effects they may experience as a result of their treatment and in turn increase help-seeking behavior and self-efficacy for the participant cohort. Quantitative data collected by the Qstream platform on the completion rates of participants will be used as a tool to evaluate the intervention. Additionally, validated scales will be used to collect data on patient self-efficacy. Qualitative data will also be collected via an exit survey and thematic content analysis of semi-structured interviews. Results The research is in the preliminary stages but thus far a protocol has been approved in support of the project. Additionally, advisory committee members have been identified and initial meetings have been undertaken. Conclusions Development of new approaches for increasing patient understanding of their care is important to ensure high quality care

    The human ability to establish cooperation, even in large groups of genetically unrelated strangers, depends upon the enforcement of cooperation norms. Third-party punishment is one important factor to explain high levels of cooperation among humans, although it is still somewhat disputed whether other animal species also use this mechanism for promoting cooperation. We study the effectiveness of third-party punishment to increase children's cooperative behavior in a large-scale cooperation game. Based on an experiment with 1,120 children, aged 7 to 11 y, we find that the threat of third-party punishment more than doubles cooperation rates, despite the fact that children are rarely willing to execute costly punishment. We can show that the higher cooperation levels with third-party punishment are driven by two components. First, cooperation is a rational (expected payoff-maximizing) response to incorrect beliefs about the punishment behavior of third parties. Second, cooperation is a conditionally cooperative reaction to correct beliefs that third party punishment will increase a partner's level of cooperation.

  8. African American Children At-Risk of Increasingly Conflicted Teacher-Student Relationships in Elementary School.

    Spilt, Jantine; Hughes, Jan N

    Previous studies found different trajectories of conflicted relationships with teachers predictive of academic underachievement. However, little is known about what places children at risk for atypical conflict trajectories. This follow-up study examines whether African American ethnicity, IQ, and SES are unique predictors of teacher-student conflict trajectories taking into account sociobehavioral predictors, including aggression and prosocial behavior. The study included the same ethnically diverse sample of 657 academically at-risk children in which previously four latent growth classes of conflict trajectories (grades 1-5) predictive of underachievement were identified. In this follow-up study, 6 predictors were examined: African American ethnicity, SES, IQ (independent assessment), Inhibitory control (performance measure), and Aggression and Prosocial behavior (peer assessment). The results demonstrated that African American ethnicity, but not IQ and SES, uniquely predicted atypical conflict trajectories, while controlling for sociobehavioral predictors. African American children were at risk of increasingly conflicted relationships with elementary school teachers, which has been found to increase the risk of academic underachievement in middle school.

    This study seeks to explore whether increased PA in school affects children's executive function and aerobic fitness. The "Active school" study was a 10-month randomized controlled trial. The sample included 449 children (10-11 years old) in five intervention and four control schools. The weekly interventions were 2×45 minutes physically active academic lessons, 5×10 minutes physically active breaks, and 5×10 minutes physically active homework. Aerobic fitness was measured using a 10-minute interval running test. Executive function was tested using four cognitive tests (Stroop, verbal fluency, digit span, and Trail Making). A composite score for executive function was computed and used in analyses. Mixed ANCOVA repeated measures were performed to analyze changes in scores for aerobic fitness and executive function. Analysis showed a tendency for a time×group interaction on executive function, but the results were non-significant F(1, 344)=3.64, P=.057. There was no significant time×group interaction for aerobic fitness. Results indicate that increased physical activity in school might improve children's executive function, even without improvement in aerobic fitness, but a longer intervention period may be required to find significant effects.

    We compared the efficacy of intranasal midazolam, ketamine and their mixture as premedication in children with tetralogy of Fallot (TOF) using bispectral index (BIS), sedation score and separation score at the time of separation from parent. Sedation score at the time of intravenous cannulation was also measured. Children with TOF physiology were randomly divided into three equal groups of 20 each. Group-A received intranasal ketamine (10 mg/Kg), Group-B received intranasal midazolam (0.2 mg/Kg), while Group-C received a mixture of ketamine (7.5 mg/Kg) and midazolam (0.1 mg/Kg) intranasally. After 30 minutes of premedication, sedation and separation score were noted. BIS values were recorded at 5 minutes intervals. A 4-point scale for sedation, separation and acceptance of intravenous cannulation was used. Sedation was good in midazolam group (group B-3.25 +/- 0.44), but the separation and acceptance of intravenous catheter was poor (2.9 +/- 0.31 and 2.85 +/- 0.37 respectively). Sedation scores in group A and C were excellent (3.75 +/- 0.44 and 3.80 +/- 0.41 respectively). Separation from parent was excellent in group A (ketamine) and group C (mixture) (group A- 3.90 +/- 0.28 and group C- 3.83 +/- 0.35 respectively). Children of both these groups allowed easy placement of intravenous cannula. At BIS values < 90, the sedation achieved was good. BIS values decreased with increase in sedation scores in groups who received intranasal midazolam and mixture containing ketamine and midazolam (group B and C respectively), while it remained high in children who received ketamine. We conclude that intranasal ketamine is better than intranasal midazolam. The combination of two is better than midazolam alone but provides no benefit as compared with ketamine alone.

    During investigation of HLA types among children exposed to diphenylhydantoin (DPH) in utero, we found no evidence of a distortion in haplotype sharing among affected sib pairs. Unexpectedly, however, we found a marked increase in the proportion of all sib pairs (not just affected ones) sharing maternal haplotypes. Among 14 two child families, 12 shared the maternal haplotype (expected would be seven); among families with more than two children the distortion was also pronounced. This finding, if verified in future studies, could indicate that something in the mothers, whether DPH use during pregnancy, or some genetic factor associated with seizures, or some effect of the seizures themselves, may be leading to non-random segregation of HLA haplotypes in their offspring.

    The clinical significance of high levels of homocysteine in autism spectrum disorder (ASD) is unknown. An experimental study was conducted in order to evaluate the concentration of homocysteine in children with ASD and typically developing children and to analyse any relationships with the severity of core symptoms of ASD and other clinical features (drugs, co-morbidities, gender, age, diet). Core symptoms of autism were evaluated by DSM-IV criteria. Homocysteine, glutathione, methionine, 3-nitrotyrosine were measured in urine. The increase in homocysteine concentration was significantly and directly correlated with the severity of the deficit in communication skills, but was unrelated to deficit in socialisation or repetitive/restricted behaviour. Urinary homocysteine concentration may be a possible biomarker for communication deficits in ASD and a potential diagnostic tool useful to evaluate new treatment options since no treatment for core symptoms of ASD are available.

    The aim of the present study was to investigate the temporal dynamics between parental behaviors in daily interactions with their offspring, that is, affection and psychological control, and children's negative emotions. The participants were 152 Finnish families with a 6- to 7-year-old child. Children's negative emotions and parental affection and psychological control in interactions with their child were measured daily using diary questionnaires filled in by the mothers and fathers over 7 successive days. The results of multilevel modeling showed that psychological control applied by mothers and fathers in daily interactions with their child leads to an increase in negative emotions in the child. Parental affection in daily interactions with their child was not associated with the child's negative emotions.

    Introduction Dental caries has been traditionally described as a multifactorial disease that involves the interaction of various factors like host, agent, substrate and time. Landmark studies have established the fact that Mutans Streptococci are the primary etiologic agents of dental caries. The prevention of dental caries by fluoride supplements in various vehicles, such as water and toothpaste, constitutes one of the most successful prevention measures. Aim The aim of the present study was to compare the clinical efficacy of four fluoride mouth rinses on Streptococcus mutans in high caries risk children and also to check the efficacy of the ingredient Triclosan which is present in two of the four mouth rinses. Materials and Methods The study is double blinded, consisting of 1000 children in age group 6-14yrs who were screened from residential schools. Of the total, 200 children were categorized as high caries risk group based on caries risk assessment tool form given by American Association of Pediatric Dentistry (AAPD) guidelines 2011. Prior to the study, salivary samples were collected and sent for microbial analysis to estimate Streptococcus mutans counts. Out of 200 salivary samples, 132 showed 106CFU of Streptococcus mutans and these children were included in the study. The 132 children from each group received the assigned mouth wash for 14 consecutive days. On 15th day the salivary samples were collected and sent for microbial analysis and the obtained results were subjected to statistical analysis. Results All the mouth washes showed a significant reduction in Colony Forming Units (CFU) counts of Streptococcus mutans. Among the four groups Group D (S flo) showed greater percentage reduction of Streptococcus mutans followed by Group A (Act), B (Kidodent) and C (Zerocary). There was no stastically significance reduction of Streptococcus mutans among the Triclosan containing and non containing groups. Conclusion The mean pre rinse CFU was significantly

    Numerous studies have demonstrated that disruptive classroom behavior can be decreased by delivering tokens contingent upon periods of time during which children do not engage in it or by removing tokens contingent upon its occurrence. To date, the best controlled of these studies have consistently reported the two procedures to be qually effective. However, in these studies, token the two procedures to be equally effective. However, in these studies, token contingencies have been combined with instructions regarding the contigencies. The present study compared these two procedures when no instructions were given regarding the token contingencies. Token delivery was not effective in decreasing disruptive behavior in any of the children, while a combination of token delivery and removal was effective for three of four children. The results token delivery and removal was effective for three of four children. The results suggest that the combined procedure may be effective with certain populations that are not readily controlled by instructions.

    Each year in the United States, 280 children die from bicycle crashes and 144,000 are treated for head injuries from bicycling. Although bicycle helmets reduce the risk of head injury by 85 percent, few children wear them. To help guide the choice of strategy to promote helmet use among children ages 5 to 16 years, the cost effectiveness of legislative, communitywide, and school-based approaches was assessed. A societal perspective was used, only direct costs were included, and a 4-year period after program startup was examined. National age-specific injury rates and an attributable risk model were used to estimate the expected number of bicycle-related head injuries and deaths in localities with and without a program. The percentage of children who wore helmets increased from 4 to 47 in the legislative program, from 5 to 33 in the community program, and from 2 to 8 in the school program. Two programs had similar cost effectiveness ratios per head injury avoided. The legislative program had a $36,643 cost and the community-based one, $37,732, while the school-based program had a cost of $144,498 per head injury avoided. The community program obtained its 33 percent usage gradually over the 4 years, while the legislative program resulted in an immediate increase in usage, thus, considering program characteristics and overall results, the legislative program appears to be the most cost-effective. The cost of helmets was the most influential factor on the cost-effectiveness ratio. The year 2000 health objectives call for use of helmets by 50 percent of bicyclists. Since helmet use in all these programs is less than 50 percent, new or combinations of approaches may be required to achieve the objective.

    The effectiveness of working memory (WM) training programmes is still a subject of debate. Previous reviews were heterogeneous with regard to participant characteristics of the studies included. To examine whether these programmes are of added value for children with learning disabilities (LDs), a systematic meta-analytic review was undertaken focusing specifically on LDs. Thirteen randomised controlled studies were included, with a total of 307 participants (age range = 5.5-17, Mean age across studies = 10.61, SD = 1.77). Potential moderator variables were examined, i.e., age, type of LD, training programme, training dose, design type, and type of control group. The meta-analysis indicated reliable short-term improvements in verbal WM, visuo-spatial WM, and word decoding in children with LDs after training (effect sizes ranged between 0.36 and 0.63), when compared to the untrained control group. These improvements sustained over time for up to eight months. Furthermore, children > 10 years seemed to benefit more in terms of verbal WM than younger children, both immediately after training as well as in the long-term. Other moderator variables did not have an effect on treatment efficacy.

    Introduction Status epilepticus (SE) is a life-threatening neurological emergency. SE lasting longer than 120 min and not responding to first-line and second-line antiepileptic drugs is defined as ‘refractory’ (RCSE) and requires intensive care unit treatment. There is currently neither evidence nor consensus to guide either the optimal choice of therapy or treatment goals for RCSE, which is generally treated with coma induction using conventional anaesthetics (high dose midazolam, thiopental and/or propofol). Increasing evidence indicates that ketamine (KE), a strong N-methyl-d-aspartate glutamate receptor antagonist, may be effective in treating RCSE. We hypothesised that intravenous KE is more efficacious and safer than conventional anaesthetics in treating RCSE. Methods and analysis A multicentre, randomised, controlled, open-label, non-profit, sequentially designed study will be conducted to assess the efficacy of KE compared with conventional anaesthetics in the treatment of RCSE in children. 10 Italian centres/hospitals are involved in enrolling 57 patients aged 1 month to 18 years with RCSE. Primary outcome is the resolution of SE up to 24 hours after withdrawal of therapy and is updated for each patient treated according to the sequential method. Ethics and dissemination The study received ethical approval from the Tuscan Paediatric Ethics Committee (12/2015). The results of this study will be published in peer-reviewed journals and presented at international conferences. Trial registration number NCT02431663; Pre-results. PMID:27311915

    The objective of the study was to develop a novel procedure to increase self-efficacy for exercise. Gains in one's ability to resolve day-to-day obstacles for entering an exercise routine were expected to cause an increase in self-efficacy for exercise. Fifty-five sedentary participants (did not exercise regularly for at least 4 months prior to the study) who expressed an intention to exercise in the near future were selected for the study. Participants were randomly assigned to one of three conditions: (1) an Experimental Group in which they received a problem-solving training session to learn new strategies for solving day-to-day obstacles that interfere with exercise, (2) a Control Group with Problem-Solving Training which received a problem-solving training session focused on a typical day-to-day problem unrelated to exercise, or (3) a Control Group which did not receive any problem-solving training. Assessment of obstacles to exercise and perceived self-efficacy for exercise were conducted at baseline; perceived self-efficacy for exercise was reassessed post-intervention (1 week later). No differences in perceived challenges posed by obstacles to exercise or self-efficacy for exercise were observed across groups at baseline. The Experimental Group reported greater improvement in self-efficacy for exercise compared to the Control Group with Training and the Control Group. Results of this study suggest that a novel procedure that focuses on removing obstacles to intended planned fitness activities is effective in increasing self-efficacy to engage in exercise among sedentary adults. Implications of these findings for use in applied settings and treatment studies are discussed.

    Children with spastic cerebral palsy (CP) have small, weak muscles. However, change in muscle size due to resistance training in this group is unknown. We investigated the effect of plantarflexor strengthening on muscle volume, gait, and function in 13 ambulant children with spastic CP (seven males, six females; mean age 10 y 11 mo, SD 3 y 0 mo, range 6 y 11 mo-16 y 11 mo; eight with diplegia, five with hemiplegia; Gross Motor Function Classification System level I, six; level II, five; level III, two). Assessments were performed before training, 5 and 10 weeks into training, and at a 3-month follow-up. Medial and lateral gastrocnemius volumes were computed from three-dimensional ultrasound images. The number of unilateral heel raises able to be achieved on each side was assessed. Function was measured using three-dimensional gait analysis, the 'timed up and go' test, the Gillette Functional Assessment Questionnaire, and the Functional Mobility Scale. Training involved heel raises or Thera-Band resistance, 4 times a week for 10 weeks. Medial and lateral gastrocnemius volumes increased by 17 and 14% at week 5 (p=0.03, p=0.028). This increase was maintained at week 10 and follow-up (medial gastrocnemius p=0.001, p<0.001; lateral gastrocnemius p=0.006, p=0.007). Heel raises (mean number) increased by week 5 (p=0.002). This was maintained at week 10 and follow-up (p<0.001; p<0.001). No significant change in measured function was observed. Muscle volume increased in response to training in children with spastic CP. The role of progressive strength training in maintaining long-term function is discussed.

    Background: Navy beans and rice bran demonstrate efficacy to regulate serum cholesterol in hypercholesterolemic adults; however, the cardiovascular disease (CVD) protective properties of these foods in children are unknown and merit investigation. Objective: The objectives were to determine whether cooked navy bean powder (NBP) and/or heat-stabilized rice bran (RB) supplementation is tolerable, improves dietary fiber intake in children, and modulates lipid profiles. Methods: Children aged 8 to 13 years at risk for CVD due to abnormal lipids were recruited. Elevated cholesterol levels were defined as total cholesterol ≥180 mg/dL and high-density lipoprotein (HDL) <60 mg/dL; low-density lipoprotein (LDL) ≥100 mg/dL and HDL <60 mg/dL; or non-HDL >100 mg/dL and HDL <60 mg/dL. Participants completed a pilot 4-week, randomized controlled, 4-arm dietary intervention. They consumed study-provided muffins or a smoothie daily that included 0 g NBP or RB (control), 17.5 g NBP, 15 g RB, or a combination 9 g NBP + 8 g RB. Fasting blood was collected at baseline and week 4. Participants also completed 3-day food logs and gastrointestinal health questionnaires. Results: Thirty-eight children completed the trial (n = 9 control, n = 10 NBP, n = 9 RB, and n = 10 NBP + RB groups). Only 3 participants withdrew due to noncompliance of required food consumption. Participants in the intervention groups significantly increased intake of NBP and RB at week 4 (p≤.01). The NBP and NBP + RB groups increased total fiber intake from baseline to week 4 (p=.02 and p=<.01, respectively). HDL-cholesterol was higher in NBP-group participants compared to control at week 4 (P = .02). Conclusion: Increasing NBP and/or RB intake is tolerable for children, and our findings suggest higher daily intakes are needed for a longer duration to induce favorable changes across multiple serum lipid parameters.

    OBJECTIVE: To evaluate the therapeutic efficacy of sulfadoxine-pyrimethamine, amodiaquine, and the sulfadoxine-pyrimethamine-amodiaquine combination for the treatment of uncomplicated Plasmodium falciparum malaria in young children in Cameroon. METHODS: In a randomized study we evaluated the effectiveness and tolerance of (i) sulfadoxine-pyrimethamine (SP) (25 mg/kg body weight of sulfadoxine and 1.25 mg/kg of pyrimethamine in a single oral dose), (ii) amodiaquine (AQ) (30 mg/kg body weight in three divided daily doses), and (iii) the sulfadoxine-pyrimethamine-amodiaquine combination (SP+AQ) (same doses as in the other two treatment groups, given simultaneously on day 0) in young children in southern Cameroon. The parasitological and clinical responses were studied until day 28 in accordance with the modified 1996 WHO protocol for the evaluation of the therapeutic efficacy of antimalarial drugs. FINDINGS: Of 191 enrolled patients, 6 and 8 were excluded or lost to follow-up before day 14 and between day 14 and day 28, respectively. For the AQ-treated patients, parasitological and clinical evaluation on day 14 showed late treatment failure in 2 of 61 (3.3%) and adequate clinical response with parasitological failure in one (1.6%). There was an adequate clinical response in all patients treated with SP or SP+AQ. Therapeutic failure rates on day 28 were 13.6%, 10.2% and 0% in the SP, AQ, and SP+AQ groups, respectively. Anaemia improved in all three regimens. AQ produced faster fever clearance but was associated with more transient minor side-effects than SP. SP+AQ reduced the risk of recrudescence between day 14 and day 28 but increased the incidence of minor side-effects. CONCLUSION: SP+AQ can be recommended as a temporary means of slowing the spread of multidrug resistance in Plasmodium falciparum in Africa while the introduction of other combinations, including artemisinin derivatives, is awaited.

    The development of resistance to antimalarials is a major challenge for global malaria control. Artemisinin-based combination therapies, the newest class of antimalarials, are used worldwide but there have been reports of artemisinin resistance in Southeast Asia. In February through May 2013, we conducted open-label, nonrandomized therapeutic efficacy studies of artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) in Zaire and Uíge Provinces in northern Angola. The parasitological and clinical responses to treatment in children with uncomplicated Plasmodium falciparum monoinfection were measured over 28 days, and the main outcome was a PCR-corrected adequate clinical and parasitological response (ACPR) proportion on day 28. Parasites from treatment failures were analyzed for the presence of putative molecular markers of resistance to lumefantrine and artemisinins, including the recently identified mutations in the K13 propeller gene. In the 320 children finishing the study, 25 treatment failures were observed: 24 in the AL arms and 1 in the DP arm. The PCR-corrected ACPR proportions on day 28 for AL were 88% (95% confidence interval [CI], 78 to 95%) in Zaire and 97% (91 to 100%) in Uíge. For DP, the proportions were 100% (95 to 100%) in Zaire, and 100% (96 to 100%) in Uíge. None of the treatment failures had molecular evidence of artemisinin resistance. In contrast, 91% of AL late-treatment failures had markers associated with lumefantrine resistance on the day of failure. The absence of molecular markers for artemisinin resistance and the observed efficacies of both drug combinations suggest no evidence of artemisinin resistance in northern Angola. There is evidence of increased lumefantrine resistance in Zaire, which should continue to be monitored.

    Evidence suggests that task-based training approaches can improve the performance of children with handwriting difficulties. The present case study tests the efficacy of the Handwriting Task Program (HTP). Three male children (9-10 yr. old) with poor handwriting skills and different developmental disorders participated in the HTP, twice per week, for 13 wk. Handwriting legibility was assessed through the Concise Evaluation Scale for Children's Handwriting, and fine motor performance and handwriting speed were evaluated at pre- and post-treatment with the Visual Motor Integration Test and the Battery for the assessment of writing skills of children from 7 to 13 yr. old. The results showed that motor efficiency and global handwriting quality improved in all the children, although some handwriting difficulties still persisted in one child with Developmental Coordination Disorder (DCD). Further study may confirm on a larger sample that a visual-spatially based training may improve the handwriting legibility of children with DCD.

    Background: Global food prices have risen sharply since 2007. The impact of food price spikes on the risk of malnutrition in children is not well understood. Objective: We investigated the associations between food price spikes and childhood malnutrition in Andhra Pradesh, one of India’s largest states, with >85 million people. Because wasting (thinness) indicates in most cases a recent and severe process of weight loss that is often associated with acute food shortage, we tested the hypothesis that the escalating prices of rice, legumes, eggs, and other staples of Indian diets significantly increased the risk of wasting (weight-for-height z scores) in children. Methods: We studied periods before (2006) and directly after (2009) India’s food price spikes with the use of the Young Lives longitudinal cohort of 1918 children in Andhra Pradesh linked to food price data from the National Sample Survey Office. Two-stage least squares instrumental variable models assessed the relation of food price changes to food consumption and wasting prevalence (weight-for-height z scores). Results: Before the 2007 food price spike, wasting prevalence fell from 19.4% in 2002 to 18.8% in 2006. Coinciding with India’s escalating food prices, wasting increased significantly to 28.0% in 2009. These increases were concentrated among low- (χ2: 21.6, P < 0.001) and middle- (χ2: 25.9, P < 0.001) income groups, but not among high-income groups (χ2: 3.08, P = 0.079). Each 10.0 rupee ($0.170) increase in the price of rice/kg was associated with a drop in child-level rice consumption of 73.0 g/d (β: −7.30; 95% CI: −10.5, −3.90). Correspondingly, lower rice consumption was significantly associated with lower weight-for-height z scores (i.e., wasting) by 0.005 (95% CI: 0.001, 0.008), as seen with most other food categories. Conclusion: Rising food prices were associated with an increased risk of malnutrition among children in India. Policies to help ensure the affordability of food

  10. Increased parent reinforcement of spontaneous requests in children with autism spectrum disorder: effects on problem behavior.

    2013-03-01

    Previous studies of response classes in individuals with developmental disabilities (DD) and problem behavior have shown that mild problem behavior, precursor behavior, and mands or requests can occur as functionally equivalent to severe problem behavior in some individuals. Furthermore, participants in some studies chose to use functionally equivalent alternatives over severe problem behavior to produce the maintaining reinforcer. The present study added to this literature by having parents reinforce spontaneous requests functionally equivalent to problem behavior in their children with autism at home. First, parent-implemented functional analyses identified conditions associated with increased problem behavior and requests in two children with autism. Then, parents provided the maintaining reinforcer contingent on problem behavior alone or both problem behavior and requests in a withdrawal design. The treatment analysis indicated that the same reinforcer maintained child requests and problem behavior. In addition, when parents reinforced both requests and problem behavior, child participants demonstrated a preference for requests, thereby decreasing problem behavior. Implications of this relation for function-based treatment of problem behavior in children with autism are discussed.

    During childhood and adolescence, physiological, psychological, and behavioral processes strongly promote weight gain and increased appetite while also inhibiting weight loss and decreased appetite. The Diagnostic and Statistical Manual-IV (DSM-IV) treats both weight-gain/increased-appetite and weight-loss/decreased-appetite as symptoms of major depression during these developmental periods, despite the fact that one complements typical development and the other opposes it. To disentangle the developmental versus pathological correlates of weight and appetite disturbance in younger age groups, the current study examined symptoms of depression in an aggregated sample of 2307 children and adolescents, 47.25% of whom met criteria for major depressive disorder. A multigroup, multidimensional item response theory model generated three key results. First, weight loss and decreased appetite loaded strongly onto a general depression dimension; in contrast, weight gain and increased appetite did not. Instead, weight gain and increased appetite loaded onto a separate dimension that did not correlate strongly with general depression. Second, inclusion or exclusion of weight gain and increased appetite affected neither the nature of the general depression dimension nor the fidelity of major depressive disorder diagnosis. Third, the general depression dimension and the weight-gain/increased-appetite dimension showed different patterns across age and gender. In child and adolescent populations, these results call into question the utility of weight gain and increased appetite as indicators of depression. This has serious implications for the diagnostic criteria of depression in children and adolescents. These findings inform a revision of the DSM, with implications for the diagnosis of depression in this age group and for research on depression.

    In adults and children, sleep loss is associated with affective dysregulation and increased responsivity to negative stimuli. Adult functional neuroimaging (fMRI) studies have demonstrated associations between restricted sleep and neural alterations in the amygdala and reward circuitry when viewing emotional picture and face stimuli. Despite this, few studies have examined the associations between short sleep duration and emotional responsivity in typically developing children, and no studies have investigated this relationship using fMRI. The current study examined the relationship between sleep duration and fMRI activation to emotional facial expressions in 15 male children (ages 7-11 years). During fMRI scanning, subjects viewed and made perceptual judgments regarding negative, neutral, and positive emotional faces. Maternal reported child sleep duration was negatively associated with (a) activation in the bilateral amygdala, left insula, and left temporal pole activation when viewing negative (i.e., fearful, disgust) vs. neutral faces, (b) right orbitofrontal and bilateral prefrontal activation when viewing disgust vs. neutral faces, and (c) bilateral orbitofrontal, right anterior cingulate, and left amygdala activation when viewing happy vs. neutral faces. Consistent with our prediction, we also noted that emotion-dependent functional connectivity between the bilateral amygdala and prefrontal cortex, cingulate, fusiform, and occipital cortex was positively associated with sleep duration. Paralleling similar studies in adults, these findings collectively suggest that decreased sleep duration in school-aged children may contribute to enhanced reactivity of brain regions involved in emotion and reward processing, as well as decreased emotion-dependent functional connectivity between the amygdala and brain regions associated with emotion regulation.

    BACKGROUND/OBJECTIVES This study measured the effects of a taste education program developed in Korea on food neophobia and willingness to try novel foods in school children. SUBJECTS/METHODS One-hundred and twenty school children (aged 7-9 years) residing in Seoul participated in 12 sessions of a taste education program for 3 months. The Korean taste education program was adapted from "Les classes du goût" by J. Puisais and modified to suit a Korean education environment. The study subjected school children to pre- and post-programs on food neophobia and willingness to try novel foods (WTNF), in addition to children's food neophobia in their parents. A total of 101 survey data were analyzed using SPSS 18.0. RESULTS Regarding the effects of taste education, scores of food neophobia significantly decreased (P < 0.01) in the posttest, mean (m) score (4.10 ± 1.19) decreased compared to the pretest (4.39 ± 1.00), and WTNF significantly increased (P < 0.001) in the pretest (m) score (0.48 ± 0.33) compared to the pretest (0.32 ± 0.34). This result indicates verification of the study hypothesis. CONCLUSIONS Food neophobia scale (FNS), an index that measures personal food preference [12], showed a very weak correlation with behavioral willingness to taste novel foods (WTNF). Therefore, it is expected that the two scales measure different things. However, considering that the traits of food neophobia are not easily changed, the taste education program was administered in a remarkably effective manner. PMID:27087907

  15. Decreased and Increased Anisotropy along Major Cerebral White Matter Tracts in Preterm Children and Adolescents

    Premature birth is highly prevalent and associated with neurodevelopmental delays and disorders. Adverse outcomes, particularly in children born before 32 weeks of gestation, have been attributed in large part to white matter injuries, often found in periventricular regions using conventional imaging. To date, tractography studies of white matter pathways in children and adolescents born preterm have evaluated only a limited number of tracts simultaneously. The current study compares diffusion properties along 18 major cerebral white matter pathways in children and adolescents born preterm (n = 27) and full term (n = 19), using diffusion magnetic resonance imaging and tractography. We found that compared to the full term group, the preterm group had significantly decreased FA in segments of the bilateral uncinate fasciculus and anterior segments of the right inferior fronto-occipital fasciculus. Additionally, the preterm group had significantly increased FA in segments of the right and left anterior thalamic radiations, posterior segments of the right inferior fronto-occipital fasciculus, and the right and left inferior longitudinal fasciculus. Increased FA in the preterm group was generally associated with decreased radial diffusivity. These findings indicate that prematurity-related white matter differences in later childhood and adolescence do not affect all tracts in the periventricular zone and can involve both decreased and increased FA. Differences in the patterns of radial diffusivity and axial diffusivity suggest that the tissue properties underlying group FA differences may vary within and across white matter tracts. Distinctive diffusion properties may relate to variations in the timing of injury in the neonatal period, extent of white matter dysmaturity and/or compensatory processes in childhood. PMID:26560745

    A systematic review was undertaken to identify intervention characteristics associated with increasing consumption of vegetables in children (2-12 years). PubMed, PsychINFO and CABabstracts were used to identify studies published between 2004-2014 that had measures of vegetable consumption, a minimum of 3-month follow-up and were conducted in home and community settings (outside of schools). Twenty-two studies were included in the review. Details of the study design, population, setting, intervention characteristics, target behaviour, behaviour change techniques used and vegetable intake were extracted. Study quality and intensity were scored. Overall, 12/22 studies were effective short-term, and 6/10 were effective long-term (6 + months); mean short-term change in vegetable intake was 29%, equating to an increase of a quarter to a half of a serving of vegetables. Intervention effectiveness was associated with number of settings targeted and frequency of contact but not length of intervention. Planning for social support, vegetable exposure and provision of staff training were commonly used behaviour change techniques in effective interventions. This review has identified strategies that may optimise effectiveness of future home-based and community-based interventions aiming to increase vegetable intake in young children.

    Patients with systemic lupus erythematosus (SLE) are prone to premature atherosclerosis and are at risk for the development of cardiovascular disease. Increased arterial stiffness is emerging as a marker of subclinical atherosclerosis. Purpose. To measure proximal aortic stiffness in children and adolescents with SLE. Methods. We studied 16 patients with SLE in activity (mean age 15 ± 2.42 years; 16 females), 14 patients with SLE not in activity (mean age 15.7 ± 1.89 years; 4 males, 10 females), and 16 age- and sex-comparable healthy children and adolescents (15.5 ± 1.71 years; 4 males, 12 females). Disease activity was determined by the SLE disease activity index (SLEDAI). All subjects underwent echocardiography for assessment of proximal aortic pulse wave velocity (PWV) [Ao distance/Ao wave transit time in the aortic arch]. Venous blood samples were collected for ESR. Results. Patients in activity had significantly higher PWV values than controls (P < 0.05), while no significant difference was found between patients not in activity and controls. Conclusions. SLE patients with disease activity demonstrate increased PWV and arterial stiffness of the proximal aorta, while patients without disease activity do not. This suggests that inflammation secondary to SLE activity, and not subclinical atherosclerosis, is the major underlying cause for increased arterial stiffness in this age group.

    The current study extends research on the impact of the Fostering Healthy Futures program (Taussig & Culhane, 2010), a 9-month mentoring and skills group preventive intervention for maltreated children, by examining whether the effect of Fostering Healthy Futures is moderated by children's baseline risk exposure (i.e., number of adverse childhood experiences). Participants included 156 racially and ethnically diverse children (ages 9-11, 50.7% female) recently placed in foster care due to maltreatment who were randomized to intervention or control conditions. Baseline and 6-month postintervention measures included a multi-informant index of mental health functioning and youth-reported symptoms of posttraumatic stress, dissociation, coping skills, social-acceptance, global self-worth, social support, and quality of life. A previously published, empirically derived risk index was used to assess level of exposure to 6 adverse childhood experiences (i.e., physical abuse, sexual abuse, removal from a single parent household, high level of exposure to community violence, and high numbers of caregiver and school transitions). Significant Intervention × Risk interactions were observed in regression models predicting 6-month postintervention symptoms of posttraumatic stress (β = .38, p < .001) and dissociation (β = .30, p < .01). Among children with low to moderate levels of risk, intervention participants evidenced fewer symptoms, whereas intervention participants with high levels of risk did not differ from the control group. The results of this study suggest that maltreated children exposed to high numbers of adverse childhood experiences may not experience the same reduction in trauma symptoms postintervention relative to children exposed to fewer adversities.

    Context While therapy for early Pa acquisition has been shown to be efficacious, the best regimen to achieve airway clearance has not been delineated. Objectives To investigate the efficacy and safety of four anti-pseudomonal treatments in children with cystic fibrosis (CF) with recently acquired Pa. Design, Setting, and Patients In a multicenter trial in the US, 304 children with CF ages 1–12 years within 6 months of Pa detection were randomized to one of four antibiotic regimens for an 18-month period (six 12-week quarters) between December 2004 and June 2009. Participants randomized to cycled therapy received tobramycin inhalation solution (300 mg BID) for 28 days, with oral ciprofloxacin (15–20 mg/kg BID) or oral placebo for 14 days every quarter, while participants randomized to culture-based therapy received the same treatments only during quarters with positive Pa cultures. Main outcome measures The primary endpoints were time to pulmonary exacerbation requiring intravenous antibiotics and proportion of Pa-positive cultures. Results The intention-to-treat analysis included 304 participants. There was no interaction between treatments. There were no statistically significant differences in exacerbation rates between cycled and culture-based groups (hazard ratio [HR], 0.95, 95%CI, 0.54–1.66) or ciprofloxacin and placebo (HR 1.45, 95%CI, 0.82–2.54). The ORs of Pa positive culture comparing cycled vs. culture-based group were 0.78 (95%CI, 0.49–1.23) and OR 1.10; 95%CI, 0.71–1.71) comparing ciprofloxacin vs. placebo. Adverse events were similar across groups. Conclusions No difference in rate of exacerbation or prevalence of Pa positivity was detected between cycled and culture-based therapies. Adding ciprofloxacin produced no benefits. PMID:21893650

    Background To assess the efficacy and safety of oxcarbazepine (OXC) in the treatment of children with epilepsy. Methods Randomized controlled trials (RCTs) published in PubMed, Embase, Web of Science, Cochrane Library, Scopus, SinoMed (Chinese BioMedical Literature Service System, China), and Chinese National Knowledge Infrastructure (China) database were systematically reviewed. Eligible studies were those that compared the efficacy and safety of OXC with other antiepileptic drugs in epilepsy. Risk ratio (RR) with 95% confidence intervals (95% CIs) was calculated using fixed-effects or random-effects model. Results Eleven RCTs with a total of 1,241 patients met the inclusion criteria and were included in this meta-analysis. Compared with other antiepileptic drugs (sodium valproate, levetiracetam, phenytoin, and placebo), OXC was associated with similar seizure-free rate (RR =1.06, 95% CI: 0.94, 1.20; P=0.366) and percentage reduction from baseline in seizure frequency (for ≥75% reduction: RR =1.15, 95% CI: 0.88, 1.49; P=0.310; for 50%–75% reduction: RR =1.12, 95% CI: 0.90, 1.39; P=0.301; for <50% reduction: RR =0.79, 95% CI: 0.56, 1.12; P=0.179). Moreover, patients treated with OXC had a comparable incidence of adverse events compared with those treated with other antiepileptic drugs (RR =1.01, 95% CI: 0.92, 1.11; P=0.760). Conclusion OXC showed similar effects and safety as other antiepileptic drugs in the treatment of children with epilepsy. Further well-conducted, large-scale RCTs are needed to validate these findings. PMID:28293110

    Previous meta-analyses of psychotherapies for child and adolescent depression were limited because of the small number of trials with direct comparisons between two treatments. A network meta-analysis, a novel approach that integrates direct and indirect evidence from randomized controlled studies, was undertaken to investigate the comparative efficacy and acceptability of psychotherapies for depression in children and adolescents. Systematic searches resulted in 52 studies (total N=3805) of nine psychotherapies and four control conditions. We assessed the efficacy at post-treatment and at follow-up, as well as the acceptability (all-cause discontinuation) of psychotherapies and control conditions. At post-treatment, only interpersonal therapy (IPT) and cognitive-behavioral therapy (CBT) were significantly more effective than most control conditions (standardized mean differences, SMDs ranged from −0.47 to −0.96). Also, IPT and CBT were more beneficial than play therapy. Only psychodynamic therapy and play therapy were not significantly superior to waitlist. At follow-up, IPT and CBT were significantly more effective than most control conditions (SMDs ranged from −0.26 to −1.05), although only IPT retained this superiority at both short-term and long-term follow-up. In addition, IPT and CBT were more beneficial than problem-solving therapy. Waitlist was significantly inferior to other control conditions. With regard to acceptability, IPT and problem-solving therapy had significantly fewer all-cause discontinuations than cognitive therapy and CBT (ORs ranged from 0.06 to 0.33). These data suggest that IPT and CBT should be considered as the best available psychotherapies for depression in children and adolescents. However, several alternative psychotherapies are understudied in this age group. Waitlist may inflate the effect of psychotherapies, so that psychological placebo or treatment-as-usual may be preferable as a control condition in psychotherapy

    Prozornaia, L P; Brzhevskiĭ, V V

    2013-01-01

    110 patients aged from 3 to 42 years old were examined to estimate the efficacy of chronic blepharitis treatment: 50 patients with chronic blepharitis and dry eye syndrome (DES), 28 with DES due to computer vision syndrome and 32 with isolated chronic blepharitis. All patients received eyelid massage. If the secretion was too thick and difficult to evacuate from meibomian glands then duct probing was performed. In addition a complex of hygienic procedures was performed using phytoproducts ("Geltec-Medika", Russia): blepharoshampoo, blepharolotion, blepharogel 1 and 2. Moist warm pads (with blepharolotion and calendula extraction) were applied on the eyelids in 25 patients. Massage and probing of meibomian gland ducts and hygienic procedures were showed to be effective in management of clinical signs of chronic blepharitis including coexisting DES. Moist warm pads improve efficacy of background therapy in patients with meibomian gland hypofunction and have no effect in blepharitis with excessive meibomian gland secretion. Eyelid hygiene was showed to be effective in adults and children as well including infants.

  8. Increased Sleep Depth in Developing Neural Networks: New Insights from Sleep Restriction in Children.

    Brain networks respond to sleep deprivation or restriction with increased sleep depth, which is quantified as slow-wave activity (SWA) in the sleep electroencephalogram (EEG). When adults are sleep deprived, this homeostatic response is most pronounced over prefrontal brain regions. However, it is unknown how children's developing brain networks respond to acute sleep restriction, and whether this response is linked to myelination, an ongoing process in childhood that is critical for brain development and cortical integration. We implemented a bedtime delay protocol in 5- to 12-year-old children to obtain partial sleep restriction (1-night; 50% of their habitual sleep). High-density sleep EEG was assessed during habitual and restricted sleep and brain myelin content was obtained using mcDESPOT magnetic resonance imaging. The effect of sleep restriction was analyzed using statistical non-parametric mapping with supra-threshold cluster analysis. We observed a localized homeostatic SWA response following sleep restriction in a specific parieto-occipital region. The restricted/habitual SWA ratio was negatively associated with myelin water fraction in the optic radiation, a developing fiber bundle. This relationship occurred bilaterally over parieto-temporal areas and was adjacent to, but did not overlap with the parieto-occipital region showing the most pronounced homeostatic SWA response. These results provide evidence for increased sleep need in posterior neural networks in children. Sleep need in parieto-temporal areas is related to myelin content, yet it remains speculative whether age-related myelin growth drives the fading of the posterior homeostatic SWA response during the transition to adulthood. Whether chronic insufficient sleep in the sensitive period of early life alters the anatomical generators of deep sleep slow-waves is an important unanswered question.

    [Purpose] The objective of this study was to clarify the effects of increased number of steps on body composition, physical functions, vascular functions, health-related quality of life (HR-QOL) and self-efficacy in elderly people. [Subjects and Methods] The subjects were 47 elderly persons who resided in Port Island in the Chuo Ward of Kobe City in Hyogo Prefecture, Japan. After the calculation of the mean preintervention physical activity (PA), the subjects were instructed to increase their PA to a target baseline + 1,300 steps/day. Body composition, physical functions, vascular functions, HR-QOL, and self-efficacy were measured at baseline, after 3 and 6 months. These items were compared between a group that increased their PA and a group that did not. [Results] After 6 months, 26.1% of the subjects achieved the PA target. No significant improvements were observed in body composition, physical functions, vascular functions, or self-efficacy for either group after 3 and 6 months. However, the HR-QOL improved significantly after 6 months in the achievement group. [Conclusion] Although the intervention to increase PA did not produce significant improvements after 6 months in body composition, physical functions, vascular functions, or self-efficacy, the HR-QOL improved significantly during this relatively short period.

    Joint attention intervention for children with autism spectrum disorders was focused on improving joint engagement and joint attention skills. The purpose of this study was to develop a caregiver-mediated joint engagement intervention program combined with body movement play to investigate the effects of joint engagement/joint attention skills in young children with autism spectrum disorders. A quasi-experimental research design was conducted. A total of 34 young children with autism spectrum disorders aged 2-4 years were separated into an intervention and a control group. The program consisted of 20 sessions, 60 min per session, twice a week, for the target child and his or her parent. The results indicated that child-initiated supportive and coordinated joint engagement was greater for the intervention group compared with the control group at 3-month follow-up. This demonstrated that our joint engagement intervention could enhance joint engagement, especially coordinated joint engagement for young children with autism spectrum disorders. The limitations of the study and future directions were discussed.

    2015-08-01

    Comprehensive evaluation of prior interventions designed to increase preschoolers' physical activity is lacking. This systematic review aimed to examine the effect of interventions on objectively measured physical activity in children aged 2-5 years. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. In May 2014, we searched PubMed, CINAHL, PsycINFO, ERIC, SPORTDiscus, Cochrane, and Embase. Two reviewers independently identified and appraised the studies. Twenty-four articles describing 23 independent studies and 20 unique interventions met inclusion criteria. Of the 8 interventions resulting in a significant effect in objectively measured physical activity, all were center-based and included a structured physical activity component, 6 included multiple components, 5 integrated theories or models, and 4 actively involved parents. Seven of the 8 were randomized controlled trials. Due to the heterogeneity of the study designs, physical activity measures, and interventions, drawing definitive conclusions was difficult. Although the overall intervention effect was less than optimal, the review indicated that theory-driven, multicomponent interventions including a structured physical activity component and targeting both parents and their children may be a promising approach for increasing preschoolers' physical activity and warrant continued investigation using rigorous designs to identify those that are most effective.

    2016-10-01

    Obesity is a growing public health concern and is more prevalent among low-income and minority populations. Food insecurity may increase the odds of obesity in children. We investigated the association between food insecurity and obesity among low-income, Hispanic, mother-child dyads (n = 74). The United States Department of Agriculture 18-item Household Food Security Survey was used to determine food security status. The majority of households were food insecure (74 %) and one-third (30 %) of children were obese. Food insecurity increased the odds of childhood obesity (OR 10.2; 95 % CI 1.2, 85.5) with stronger associations found within households where mothers were also overweight/obese compared to normal weight (p-for interaction < 0.05). Rates of household food insecurity and childhood obesity were high among this low-income Hispanic sample. Future studies should elucidate the mechanisms through which food insecurity impacts childhood obesity.

    AIM: To investigate the potential association of circulating zonulin with the stage of liver disease in obese children with biopsy-confirmed nonalcoholic fatty liver disease (NAFLD). METHODS: A case-control study was performed. Cases were 40 obese children with NAFLD. The diagnosis of NAFLD was based on magnetic resonance imaging (MRI) with high hepatic fat fraction (HFF ≥ 5%), and confirmed by liver biopsy with ≥ 5% of hepatocytes containing macrovesicular fat. Controls were selected from obese children with normal levels of aminotransferases, and without MRI evidence of fatty liver as well as of other causes of chronic liver diseases. Controls were matched (1-to 1) with the cases on age, gender, pubertal stage and as closely as possible on body mass index- standard deviation score. All participants underwent clinical examination, laboratory tests including zonulin, inflammatory and metabolic parameters, and MRI for measurement of HFF and visceral adipose tissue. RESULTS: Zonulin values were significantly greater in obese subjects with NAFLD than in those without NAFLD [median (interquartile range), 4.23 (3.18-5.89) vs 3.31 (2.05-4.63), P < 0.01]. In patients with NAFLD, zonulin concentrations increased significantly with the severity of steatosis and the Spearman’s coefficient revealed a positive correlation between zonulin values and steatosis (r = 0.372, P < 0.05); however, we did not find a significant correlation between zonulin and lobular inflammation (P = 0.23), ballooning (P = 0.10), fibrosis score (P = 0.18), or presence of nonalcoholic steatohepatitis (P = 0.17). Within the entire study population, zonulin levels were positively associated with gamma-glutamyl transferase, 2-h insulin, HFF, and negatively associated with whole-body insulin sensitivity index (WBISI), after adjustment for age, gender and pubertal status. When the associations were restricted to the group of NAFLD patients, 2-h insulin, hepatic fat, and WBISI retained statistical

    PubMed

    Gripshover, Sarah J; Markman, Ellen M

    2013-08-01

    In two experiments, we used a novel approach to educating young children about nutrition. Instead of teaching simple facts, we provided a rich conceptual framework that helped children understand the need to eat a variety of healthy foods. Using the insight that children's knowledge can be organized into coherent belief systems, or intuitive theories, we (a) analyzed the incipient knowledge that guides young children's reasoning about the food-body relationship, (b) identified the prerequisites that children need to conceptualize food as a source of nutrition, and (c) devised a strategy for teaching young children a coherent theory of food as a source of diverse nutrients. In these two experiments, we showed that children can learn and generalize this conceptual framework. Moreover, this learning led children to eat more vegetables at snack time. Our findings demonstrate that young children can benefit from an intervention that capitalizes on their developing intuitive theories about nutrition.

  18. Updated guidance for palivizumab prophylaxis among infants and young children at increased risk of hospitalization for respiratory syncytial virus infection.

    PubMed

    2014-08-01

    Guidance from the American Academy of Pediatrics (AAP) for the use of palivizumab prophylaxis against respiratory syncytial virus (RSV) was first published in a policy statement in 1998. Guidance initially was based on the result from a single randomized, placebo-controlled clinical trial conducted in 1996-1997 describing an overall reduction in RSV hospitalization rate from 10.6% among placebo recipients to 4.8% among children who received prophylaxis. The results of a second randomized, placebo-controlled trial of children with hemodynamically significant heart disease were published in 2003 and revealed a reduction in RSV hospitalization rate from 9.7% in control subjects to 5.3% among prophylaxis recipients. Because no additional controlled trials regarding efficacy were published, AAP guidance has been updated periodically to reflect the most recent literature regarding children at greatest risk of severe disease. Since the last update in 2012, new data have become available regarding the seasonality of RSV circulation, palivizumab pharmacokinetics, the changing incidence of bronchiolitis hospitalizations, the effects of gestational age and other risk factors on RSV hospitalization rates, the mortality of children hospitalized with RSV infection, and the effect of prophylaxis on wheezing and palivizumab-resistant RSV isolates. These data enable further refinement of AAP guidance to most clearly focus on those children at greatest risk.

    2015-09-01

    Three case reports on conservative treatment of posttraumatic open conquassant wounds in children are presented. In 2 cases, the wounds opened after rejection of a previously applied skin graft, whereas in the third case, the wound was consequential to toe amputation and treated conservatively. Based on the authors' long-standing favorable experience with this type of dressing in healing of deep burns in children, treatment was continued with the use of a hydrofiber supportive silver-containing dressing (AQUACEL Ag, ConvaTec, Bridgewater, NJ). From the beginning of treatment, wound dressing was performed on an outpatient basis and without antibiotic therapy. The wounds healed within 4-8 weeks. The process of wound healing and treatment, the mechanisms that may compromise it, and the possibilities offered by hydrofiber silver dressing in conservative treatment of posttraumatic conquassant skin wounds are discussed.

    While the neuroprotective benefits of estrogen and progesterone in critical illness are well established, the data regarding the effects of androgens are conflicting. Surgical repair of congenital heart disease is associated with significant morbidity and mortality, but there are scant data regarding the postoperative metabolism of sex steroids in this setting. The objective of this prospective observational study was to compare the postoperative sex steroid patterns in pediatric patients undergoing major cardiac surgery (MCS) versus those undergoing less intensive non-cardiac surgery. Urinary excretion rates of estrogen, progesterone, and androgen metabolites (μg/mmol creatinine/m(2) body surface area) were determined in 24-h urine samples before and after surgery using gas chromatography-mass spectrometry in 29 children undergoing scheduled MCS and in 17 control children undergoing conventional non-cardiac surgery. Eight of the MCS patients had Down's syndrome. There were no significant differences in age, weight, or sex between the groups. Seven patients from the MCS group showed multi-organ dysfunction after surgery. Before surgery, the median concentrations of 17β-estradiol, pregnanediol, 5α-dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA) were (control/MCS) 0.1/0.1 (NS), 12.4/11.3 (NS), 4.7/4.4 (NS), and 2.9/1.1 (p=0.02). Postoperatively, the median delta 17β-estradiol, delta pregnanediol, delta DHT, and delta DHEA were (control/MCS) 0.2/6.4 (p=0.0002), -3.2/23.4 (p=0.013), -0.6/3.7 (p=0.0004), and 0.5/4.2 (p=0.004). Postoperative changes did not differ according to sex. We conclude that MCS, but not less intensive non-cardiac surgery, induced a distinct postoperative increase in sex steroid levels. These findings suggest that sex steroids have a role in postoperative metabolism following MCS in prepubertal children.
