The effectiveness of a fundamental motor skill intervention in pre-schoolers with motor problems depends on gender but not environmental context
This study evaluated the effect of a 10-week fundamental motor skill programme in pre-schoolers with motor problems. Alongside the general effect of the intervention, we also explored possible gender differences and the role of the environmental context (living community, socio-economic status, and recreational space inside/outside the house). The intervention group (n=47; 20 ♂ and 27 ♀) received twenty 60-min motor skill sessions (2 per week) in addition to the regular physical education curriculum for pre-schoolers; the control group (n=46; 21 ♂ and 25 ♀) did not receive additional practice. General motor competence, and locomotor and object control subscales, were assessed before and after the intervention using the Test of Gross Motor Development 2nd edition (TGMD-2). Data regarding environmental factors were gathered through a questionnaire. A Group×Gender×Time ANOVA revealed that the intervention group benefited significantly from the intervention and scored better than the control group at the post-test for general motor competence and both sub-categories (locomotor and object control skill). Moreover, the intervention programme was found to be effective in helping 49% of the intervention group to achieve an average motor skill level, according to the TGMD-2 norms, while a further decline in motor competence was observed in the control group. Interestingly, the effect appeared to be gender-specific, since object control skill improved only in girls of the intervention group. Considering the environmental context, none of the above-mentioned factors was found to have an influence on the effectiveness of the intervention. The present study highlights the need for an early motor skill programme with a gender-specific approach in order to help low skilled boys and girls master a diverse set of motor skills
A randomized controlled trial of three years growth hormone and gonadotropin-releasing hormone agonist treatment in children with idiopathic short stature and intrauterine growth retardation
We assessed the effectiveness and safety of 3 yr combined GH and GnRH
agonist (GnRHa) treatment in a randomized controlled study in children
with idiopathic short stature (ISS) or intrauterine growth retardation
(IUGR). Gonadal suppression, GH reserve, and adrenal development were
assessed by hormone measurements in both treated children and controls
during the study period. Thirty-six short children, 24 girls (16 ISS/8
IUGR) and 12 boys (8 ISS/4 IUGR), with a height SD score of -2 SD or less
in early puberty (girls, B2-3; boys, G2-3), were randomly assigned to
treatment (n = 18) with GH (genotropin 4 IU/m(2). day) and GnRHa
(triptorelin, 3.75 mg/28 days) or no treatment (n = 18). At the start of
the study mean (SD) age was 11.4 (0.56) or 12.2 (1.12) yr whereas bone age
was 10.7 (0.87) or 10.9 (0.63) yrs in girls and boys, respectively. During
3 yr of study height SD score for chronological age did not change in both
treated children and controls, whereas a decreased rate of bone maturation
after treatment was observed [mean (SD) 0.55 (0.21) 'yr'/yr vs. 1.15
(0.37) 'yr'/yr in controls, P < 0.001, girls and boys together]. Height SD
score for bone age and predicted adult height increased significantly
after 3 yr of treatment; compared with controls the predicted adult height
gain was 8.0 cm in girls and 10.4 cm in boys. Furthermore, the ratio
between sitting height/height SD score decreased significantly in treated
children, whereas body mass index was not influenced by treatment. Puberty
was effectively arrested in the treated children, as was confirmed by
physical examination and prepubertal testosterone and estradiol levels.
GH-dependent hormones including serum insulin-like growth factor I and II,
carboxy terminal propeptide of type I collagen, amino terminal propeptide
of type III collagen, alkaline phosphatase, and osteocalcin were not
different between treated children and controls during the study period.
Thus, a GH dose of 4 IU/m(2) seems adequate for stabilization of the GH
reserve and growth in these GnRHa-treated children. We conclude that 3 yr
treatment with GnRHa was effective in suppressing pubertal development and
skeletal maturation, whereas the addition of GH preserved growth velocity
during treatment. This resulted in a considerable gain in predicted adult
height, without demonstrable side effects. Final height results will
provide the definite answer on the effectiveness of this combined
treatment
Atosiban versus fenoterol as a uterine relaxant for external cephalic version: randomised controlled trial
Objective To compare the effectiveness of the oxytocin receptor antagonist atosiban with the beta mimetic fenoterol as uterine relaxants in women undergoing external cephalic version (ECV) for breech presentation. Design Multicentre, open label, randomised controlled trial. Setting Eight hospitals in the Netherlands, August 2009 to May 2014. Participants 830 women with a singleton fetus in breech presentation and a gestational age of more than 34 weeks were randomly allocated in a 1:1 ratio to either 6.75 mg atosiban (n=416) or 40 ÎĽg fenoterol (n=414) intravenously for uterine relaxation before ECV. Main outcome measures The primary outcome measures were a fetus in cephalic position 30 minutes after the procedure and cephalic presentation at delivery. Secondary outcome measures were mode of delivery, incidence of fetal and maternal complications, and drug related adverse events. All analyses were done on an intention-to-treat basis. Results Cephalic position 30 minutes after ECV occurred significantly less in the atosiban group than in the fenoterol group (34% v 40%, relative risk 0.73, 95% confidence interval 0.55 to 0.93). Presentation at birth was cephalic in 35% (n=139) of the atosiban group and 40% (n=166) of the fenoterol group (0.86, 0.72 to 1.03), and caesarean delivery was performed in 60% (n=240) of women in the atosiban group and 55% (n=218) in the fenoterol group (1.09, 0.96 to 1.20). No significant differences were found in neonatal outcomes or drug related adverse events. Conclusions In women undergoing ECV for breech presentation, uterine relaxation with fenoterol increases the rate of cephalic presentation 30 minutes after the procedure. No statistically significant difference was found for cephalic presentation at delivery
Effect of diet-induced weight loss on lipoprotein(a) levels in obese individuals with and without type 2 diabetes
_Aims/hypothesis:_ Elevated levels of lipoprotein(a) [Lp(a)] are an independent risk factor for cardiovascular disease (CVD), particularly in individuals with type 2 diabetes. Although weight loss improves conventional risk factors for CVD in type 2 diabetes, the effects on Lp(a) are unknown and may influence the long-term outcome of CVD after diet-induced weight loss. The aim of this clinical study was to determine the effect of diet-induced weight loss on Lp(a) levels in obese individuals with type 2 diabetes.
_Methods:_ Plasma Lp(a) levels were determined by immunoturbidimetry in plasma obtained before and after 3–4 months of an energy-restricted diet in four independent study cohorts. The primary cohort consisted of 131 predominantly obese patients with type 2 diabetes (cohort 1), all participants of the Preven

An esthetic evaluation of unilateral canine substitution for a missing maxillary lateral incisor
Objectives: The aim of this study is to determine whether variation in size, morphology, and color of a unilateral substituted maxillary canine has influence on the dentogingival attractiveness perceived by dental professionals and laypeople.
Materials and Methods: A frontal clinical photograph of a patient with unilateral canine substitution was used as standard picture. Five different series were created by modification of following parameters with a raster graphics editor (Photoshop CS 6): (1) width, (2) color, (3) gingival margin height, and (4) crown tip morphology of the substituted canine and (5) the gingival margin height of the neighboring first premolar. For each parameter, the photograph deviating the most from the standard photograph, was combined into a final series. Four groups of examiners (orthodontists, periodontists, dentists, and laypeople) were asked to rank the photographs from most to least attractive.
Results: One hundred seventy-four examiners ranked the photographs in order of attractiveness. Overall, a darker canine color (mean rank 4.361.03) and a more pronounced canine tip morphology (mean rank 3.471.11) were significantly ranked as most unattractive (P<.05). The gingival height of the neighboring premolar was ranked as least unattractive by all groups of examiners (mean rank 1.30 +/- 0.74).
Conclusions: Darker canine color and a pronounced tip morphology of a substituted canine are rated as the most unattractive by dental professionals and laypeople.
CLINICAL SIGNIFICANCE: The present study showed that the canine color and crown tip morphology are important parameters when considering unilateral canine substitution, both for professionals and laypeople. There is a general preference in favor of canines with a light color and a reduced incisal tip

A systematic digital questionnaire system as used for Development First! 0-6 may result in early identification of developmental delay in day care facilities. This allows in turn early preventive activities to stimulate development. Evaluation of Development First! 0-6 has been done in a group of children who were offered placement in day care based on a need for support of their families. Results of Development First!0-6 are related to standardized tests like the Bayley-III-NL and the WPPSI
Harmonization of breast cancer radiotherapy treatment planning in the Netherlands
Purpose: The aim was to reach consensus in The Netherlands on which parameters should be used to evaluate breast cancer radiotherapy (RT) plans. Materials and methods: A Benchmark Case with delineated planning target volumes (PTVs) and Organs At Risk (OARs) was sent to all Dutch radiotherapy centres in combination with a questionnaire, with the request to generate RT plans prescribing 15 times 2.67 Gy for four different treatment indications according to the institutional irradiation technique. The plans and accompanying questionnaire answers were analysed using descriptive statistics. These results, together with a harmonisation proposal, were sent to all centres. The proposal was discussed at a meeting of the Dutch Society of Radiation Oncology breast cancer platform. Distinct parameters were accepted if consensus on them was reached. Results: 19 out of 20 Dutch departments participated in this study. PTV coverage varied considerably, with D98% between 63% and 99% for the breast and between 37% and 97% for the internal mammary nodes (IMN). Also substantial OAR dose differences were observed, with e.g. mean heart doses ranging between 1.85 Gy and 5.42 Gy in case the IMN were included in the PTV. For evaluation of the PTVs D98%, D2% and Dmean were chosen to report on, with target values of ≥ 95% (90% for the PTV_IMN), ≤ 107%, and 99–101%, respectively. For OARs, consensus was reached on the parameters to be evaluated, without target values: Dmean of the heart, Dmean and V5% of the lungs, and in case of periclavicular radiotherapy V30Gy of the thyroid gland. For patients younger than 40 years a contralateral mean breast dose of ≤ 1 Gy was agreed upon. Conclusion: A new Dutch consensus guideline for evaluation of breast cancer RT plans has been established
