In a retrospective, population based cohort study, we examined whether constitutional delay was associated with the growth response to growth hormone (GH) in children with short stature and normal GH responses. 70 patients were treated with 21 GH iu/m2/week from 1975 to 2013 throughout New Zealand. Demographic and auxological data were prospectively collected and standard deviation scores (SDS) were calculated for height (HtSDS), yearly growth velocity (GV-SDS), body mass index (BMI-SDS) and predicted adult height (PAH-SDS) at time of the last available bone age. In the first year, GH was associated with marked increase in HtSDS (+0.46 (0.19, 0.76), p < 0.001) and GV-SDS (from -1.9 (-3.6, -0.7) to +2.7 (0.45, 4.2), p < 0.001). The increase in HtSDS but not in GV-SDS was greatest with younger patients and greater bone age delay, with no effect of sex, BMI-SDS or baseline HtSDS. PAH-SDS increased with treatment (+0.94 (0.18, 1.5)); increased PAH-SDS was associated with less bone age delay and greater initial increase in HtSDS. This study shows that greater bone age delay was associated with greater initial improvement in height but less improvement in predicted adult heights, suggesting that children with very delayed bone ages may show accelerated maturation during GH treatment.

Knowledge of patterns of neuropsychological performance among normal, healthy individuals is integral to the practice of clinical neuropsychology, because clinicians may not always account for intraindividual variability (IIV) before coming to diagnostic conclusions. The IIV was assessed among a sample of 46 healthy individuals with high average intelligence and educational attainment, utilizing a battery of neuropsychological tests, including the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) and Wechsler Memory Scale, Fourth Edition (WMS-IV). The data indicated substantial variability in neurocognitive abilities. All participants were found to demonstrate scores considered impaired by at least 2 standard deviations (SDs). Despite adjusting for outliers, no participant produced a "normal" testing profile with an intraindividual maximum discrepancy (MD) of less than 1 SD in either direction. When WAIS-IV Full Scale IQ (FSIQ) was considered, participants generally demonstrated cognitive test scores ranging from 2 SDs less than to 1.5 SDs greater than their FSIQ. Furthermore, after demographic corrections, the majority (59%) of participants demonstrated at least 1 impaired cognitive test score, as defined by being 1 to 1.5 SDs below the mean. Overall, results substantiate the need for clinicians to consider FSIQ and educational attainment in interpretation of neuropsychological testing results, given the relevant commonality of "abnormal" test scores within this population. This may ultimately reduce the likelihood of making false-positive conclusions of impairment when educational attainment and intelligence are high, thus improving diagnostic accuracy.

Adverse childhood experiences (maltreatment and household dysfunction) are associated with adult cardiovascular disease (CVD). One possible pathway is through physical development, which has been linked to CVD risk. Our aim was to examine whether adverse childhood experiences are associated with child-to-adult height trajectories. The 1958 British birth cohort (n=17,638) includes all born in one week in March 1958, followed up to mid adulthood. Height was measured at 7, 11 and 16 years (y) and adulthood (converted to standard deviation scores (SDS); ≥1 height measurement n=16,444, adult leg length n=9180). Multivariate response models were used to examine the associations between childhood experiences (ascertained at 7 y and self-reported at 45 y) and child-to-adult height. Childhood neglect, prospectively assessed at 7 y, was associated with shorter stature throughout childhood: for each increment across a score ranging 0-7, average height reduced by 0.06 SDS (males) and 0.05 SDS (females) at 7 y (≈0.3 cm), with smaller deficits (0.03 SDS, ≈0.2 cm) in adulthood, after adjustment for parental height, birthweight and socio-economic factors. In males, the adult deficit was mainly due to shorter leg length. Household dysfunction was associated with shorter stature at 7-11 y, with adjusted deficits from 0.04 to 0.07 SDS per increment across a score ranging 0-7, but not at later ages. Adjusted models showed no associations for retrospectively reported abuse or neglect to 16 y. Those with a higher neglect score by 7 y grew more slowly, with deficits through to adulthood. No associations were found for abuse over the longer period to 16 y. Deficits associated with early life neglect and household dysfunction might have implications for adult CVD risks.

Objectives The use of growth hormone (GH) in idiopathic short stature (ISS) has been a subject of debate for the past two decades. We sought to assess the effect of GH on final height (FH) in patients with ISS in our region, which has a high consanguinity rate, and compare it to the effect observed in GH deficient (GHD) patients. Methods We conducted a retrospective chart review from 1 January 2005 to 31 December 2013 for patients with ISS or GHD from the local United Arab Emirates population who received GH treatment and were followed-up regularly in our clinic. The change in height Z-score at 12 months and FH were assessed within each group and between the two groups. Results Twenty-one patients with ISS and 29 patients with GHD were studied. There was a significant change in height Z-score at 12 months and FH in both groups (p < 0.001). The improvement in the ISS group was comparable to the response seen in GHD patients at 12 months (0.5±0.3 standard deviation score (SDS), and 0.5±0.4 SDS, respectively; p = 0.540). The effect on FH was better in ISS group than the GHD group of all etiologies (1.3±0.6 SDS vs. 0.9±0.7 SDS, respectively; p = 0.050), there was no difference between the ISS and the subgroup of idiopathic GHD (1.3±0.5 SDS and 1.2±0.8 SDS, respectively). Conclusions In our local population, GH has a positive effect on the short-term growth and FH of children with ISS to the same extent that has been observed in children with idiopathic GH deficiency.

Malnutrition in childhood cancer patients has been associated with lower health-related quality of life (HRQOL). However, this association has never actually been tested. Therefore, we aimed to determine the association between nutritional status and HRQOL in children with cancer. In 104 children, aged 2-18 years and diagnosed with hematological, solid, or brain malignancies, nutritional status and HRQOL were assessed at diagnosis and at 3, 6, and 12 months using the child- and parent-report versions of the PedsQL 4.0 Generic scale and the PedsQL 3.0 Cancer Module. Scores on both scales range from 0 to 100. Undernourished children (body mass index (BMI) or fat-free mass < -2 standard deviation score (SDS)) reported significantly lower PedsQL scores compared with well-nourished children on the domains physical functioning (-13.3), social functioning (-7.0), cancer summary scale (-5.9), and nausea (-14.7). Overnourished children (BMI or fat mass >2 SDS) reported lower scores on emotional (-8.0) and cognitive functioning (-9.2) and on the cancer summary scale (-6.6), whereas parent-report scores were lower on social functioning (-7.5). Weight loss (>0.5 SDS) was associated with lower scores on physical functioning (-13.9 child-report and -10.7 parent-report), emotional (-7.4) and social functioning (-6.0) (child-report), pain (-11.6), and nausea (-7.8) (parent-report). Parents reported worse social functioning and more pain in children with weight gain (>0.5 SDS) compared with children with stable weight status. Undernutrition and weight loss were associated with worse physical and social functioning, whereas overnutrition and weight gain affected the emotional and social domains of HRQL. Interventions that improve nutritional status may contribute to enhanced health outcomes in children with cancer.

Growth hormone (GH) deficiency may be associated with histological progression of non-alcoholic fatty liver disease (NAFLD) which includes non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH). Insulin-like growth factor 1 (IGF-1) is mainly produced by hepatocytes and its secretion is stimulated by GH. Our aim was to determine whether more histologically advanced NAFLD is associated with low circulating levels of IGF-1 in Japanese patients. Serum samples were obtained in 199 Japanese patients with biopsy-proven NAFLD and in 2911 sex- and age-matched healthy people undergoing health checkups. The serum levels of IGF-1 were measured using a commercially available immunoradiometric assay. The standard deviation scores (SDS) of IGF-1 according to age and sex were also calculated in NAFLD patients. The serum IGF-1 levels in NAFLD patients were significantly lower (median, 112 ng/mL) compared with the control population (median, 121 ng/mL, P < 0.0001). IGF-1 SDS less than -2.0 SD from median were found in 11.6% of 199 patients. NASH patients exhibited significantly lower levels of IGF-1 SDS (n = 130; median, -0.7) compared with NAFL patients (n = 69; median, -0.3; P = 0.026). The IGF-1 SDS values decreased significantly with increasing lobular inflammation (P < 0.001) and fibrosis (P < 0.001). In multiple regressions, the association between the IGF-1 SDS values and the severity of NAFLD persisted after adjusting for age, sex and insulin resistance. Low levels of circulating IGF-1 may have a role in the development of advanced NAFLD, independent of insulin resistance. Supplementation with GH/IGF-1 may be a candidate for the treatment of NASH. © 2014 The Japan Society of Hepatology.

Early diagnosis of Turner syndrome (TS) is necessary to facilitate appropriate management, including growth promotion. Not all girls with TS have overt short stature, and comparison with parental height (Ht) is needed for appropriate evaluation. We examined both the prevalence and diagnostic sensitivity of measured parental Ht in a dedicated TS clinic between 1989 and 2013. Lower end of parental target range (LTR) was calculated as mid-parental Ht (correction factor 12.5 cm minus 8.5 cm) and converted to standard deviation scores (SDS) using UK 1990 data, then compared with patient Ht SDS at first accurate measurement aged > 1 year. Information was available in 172 girls of whom 142 (82.6%) were short at first measurement. However, both parents had been measured in only 94 girls (54.6%). In 92 of these girls age at measurement was 6.93 ± 3.9 years, Ht SDS vs LTR SDS - 2.63 ± 0.94 vs - 1.77 ± 0.81 (p < 0.001), Ht SDS < LTR in 78/92 (85%). Eleven of the remaining 14 girls were < 5 years, while karyotype was 45,X/46,XX in 2 and 45,X/47,XXX in 3. This study confirms the sensitivity of evaluating height status against parental height but shows that the latter is not being consistently measured. What is Known: • Girls with Turner syndrome are short in relation to parental heights, with untreated final height approximately 20 cm below female population mean. • Measured parental height is more accurate than reported height. What is New: • In a dedicated Turner clinic, there was 85% sensitivity when comparing patient height standard deviation score at first accurate measurement beyond 1 year of age with the lower end of the parental target range standard deviation. • However, measured height in both parents had been recorded in only 54.6% of the Turner girls attending the clinic. This indicates the need to improve the quality of growth assessment in tertiary care.

Growth impairment, microcephaly and developmental delay in young children with chronic renal failure improve after successful renal transplantation. There have been few reports on head circumference (HC) and development after transplantation. Standard deviation scores (SDS) of height and HC and developmental quotient (DQ) after successful renal transplantation were evaluated in 12 recipients under 5 years of age. At the time of transplantation their mean age was 2.5 years and mean bodyweight was 9.0 kg. Mean height SDS was -3.0 at transplantation and increased to -2.3 at 1 year after transplant (P = 0.002). Mean HC-SDS increased from -1.4 to -0.9 at 1 year after transplant (P = 0.02). As for each category of DQ examined 1 year after transplant, mean scores of gross motor function, basic practice, personal relations, speech and recognition increased from 69 to 90 (P = 0.007), from 77 to 102 (P = 0.02), from 87 to 103 (P = 0.04), from 71 to 90 (P = 0.0006), and from 88 to 101 (P = 0.03), respectively. In young children, physical growth, HC growth and DQ scores increased 1 year after transplantation. Dialysis and transplantation program should be planned in young children with end-stage renal failure in anticipation of growth and development of each patient.

The perinatal-neonatal course of very-low-birth-weight (VLBW) infants might affect their childhood growth. We evaluated the effect of parental anthropometry and perinatal and neonatal morbidity of VLBW neonates on their childhood growth. We obtained parental anthropometry, height and weight at age 6-10.5 years of 334 children born as VLBW infants. Parental, perinatal and neonatal data of these children were tested for association with childhood anthropometry. (1) Maternal and paternal weight standard deviation score (SDS) and discharge weight (DW) SDS were associated with childhood weight SDS (R(2)= 0.111, p < 0.00001); (2) Maternal and paternal height SDS, corrected gestational age (GA) at discharge, maternal assisted reproduction and SGA status were associated with childhood height SDS (R(2)= 0.208, p < 0.00001); (3) paternal weight SDS, DW SDS and surfactant therapy were associated with childhood body mass index (BMI) SDS (R(2)= 0.096, p < 0.00001). 31.1% of VLBW infants had DW SDS < -1.88, and are to be considered small for gestational age ('SGA'). One quarter of these infants did not catch up by age 6-10.5 years. Childhood anthropometry of VLBW infants depends on parental anthropometry, postnatal respiratory morbidity and growth parameters at birth and at discharge. Almost one-third of VLBW premature infants had growth restriction at discharge from neonatal intensive care unit (NICU), a quarter of whom did not catch up by age 6-10.5 years.

The insulin tolerance test (ITT) is the gold standard for assessment of ACTH and GH reserve in patients with suspected hypopituitarism. It is labor intensive and costly. The objective of the study was to determine whether use of the overnight metyrapone test (OMT) and plasma IGF-I sd scores (SDS) could provide a cost-effective alternative to the ITT. This was a retrospective chart review. The study was conducted at a teaching hospital. Charts from 100 patients with organic pituitary disorders were reviewed. All underwent the OMT unless 0900 h plasma cortisol was less than 80 or greater than 450 nmol/liter when ACTH deficiency or ACTH sufficiency, respectively, was diagnosed. Patients were considered GH deficient if the age-related IGF-I SDS was less than -3 or if they had three or more other pituitary hormone deficiencies. Patients were considered GH sufficient if age-related IGF-I SDS was greater than the 95th centile established from patients with known GH deficiency. Thirty-three underwent an ITT. The proportion of patients in whom ACTH and GH reserve could be assessed using OMT/IGF-I SDS was measured. The concordance with results was obtained from ITT. Fifty-five patients were ACTH sufficient and 45 were ACTH deficient. Twenty-one were GH sufficient and 33 were GH deficient based on IGF-I SDS and other pituitary hormone deficiencies, whereas 46 could not be classified. There was near-uniform concordance between OMT/IGF-I SDS and ITT. Initial investigation using OMT/IGF-I SDS resulted in a significant cost saving. ACTH and GH reserve can be accurately and cost-effectively investigated using OMT/IGF-I SDS in approximately 50% of patients with organic pituitary disorders.

Most breast-fed newborns get the milk they need. However, very rarely milk intake is insufficient mostly as a result of poor breastfeeding techniques. Dramatic weight loss and hypernatremic dehydration may occur. Our aim was to construct charts for weight loss. A case-control study was performed. Charts with standard deviation score (SDS) lines for weight loss in the first month were constructed for 2,359 healthy breast-fed term newborns and 271 cases with breastfeeding-associated hypernatremic dehydration with serum sodium level > 149 mEq/L. Day 0 was defined as the day of birth. Many cases with (or who will develop) hypernatremic dehydration (84%; +1 SDS line) fell below the -1 SDS line at day 3, the -2 SDS line at day 4, and the -2.5 SDS line at day 5 in the chart of the healthy breast-fed newborns. Weight loss of cases with permanent residual symptoms was far below the -2.5 SDS. Already at an early age, weight loss differs between healthy breast-fed newborns and those with hypernatremic dehydration. Charts for weight loss are, therefore, useful tools to detect early, or prevent newborns from developing, breastfeeding-associated hypernatremic dehydration, and also to prevent unnecessary formula supplementing. © 2014 Wiley Periodicals, Inc.

Although recombinant human growth hormone (rhGH) is not approved to treat short stature of achondroplasia (ACH), some studies suggested growth improvement during short-term rhGH treatment. A meta-analysis of rhGH therapy efficacy in ACH children was performed. From 12 English-language studies, 558 (54.0% males) rhGH-treated ACH children were enrolled. Administration of rhGH (median dosage 0.21 mg/kg/ week; range 0.16-0.42 mg/kg/week) improved height (Ht) from baseline [-5.069 standard deviation score (SDS; 95% CI -5.109 to -5.029); p < 0.0001] to 12 [-4.325 SDS (95% CI -4.363 to -4.287); p < 0.0001] and 24 months [-4.073 SDS (95% CI -4.128 to -4.019); p < 0.0001]. Then, Ht remained approximately constant up to 5 years [-3.941 SDS (95% CI -4.671 to -3.212); p < 0.0001]. In ACH children, rhGH treatment increased Ht from -5.0 to -4.0 SDS during 5 years, but insufficient data are available on both the adult Ht and the changes of body proportions. © 2016 S.

Training in medicine must move to an outcome-based approach. A proficiency-based progression outcome approach to training relies on a quantitative estimation of experienced operator performance. We aimed to develop a method for dealing with atypical expert performances in the quantitative definition of surgical proficiency. In study one, 100 experienced laparoscopic surgeons' performances on virtual reality and box-trainer simulators were assessed for two similar laparoscopic tasks. In study two, 15 experienced surgeons and 16 trainee colorectal surgeons performed one simulated hand-assisted laparoscopic colorectal procedure. Performance scores of experienced surgeons in both studies were standardized (i.e. Z-scores) using the mean and standard deviations (SDs). Performances >1.96 SDs from the mean were excluded in proficiency definitions. In study one, 1-5% of surgeons' performances were excluded having performed significantly below their colleagues. Excluded surgeons made significantly fewer correct incisions (mean = 7 (SD = 2) versus 19.42 (SD = 4.6), P < 0.0001) and a greater proportion of incorrect incisions (mean = 45.71 (SD = 10.48) versus 5.25 (SD = 6.6), P < 0.0001). In study two, one experienced colorectal surgeon performance was >4 SDs for time to complete the procedure and >6 SDs for path length. After their exclusions, experienced surgeons' performances were significantly better than trainees for path length: P = 0.031 and for time: P = 0.002. Objectively assessed atypical expert performances were few. Z-score standardization identified them and produced a more robust quantitative definition of proficiency. © 2018 Royal Australasian College of Surgeons.

Down syndrome (DS) is associated with short stature and psychomotor delay. We have previously shown that growth hormone (GH) treatment during infancy and childhood normalizes growth velocity and improves fine motor skill performance in DS. The aim of this study was to investigate late effects of early GH treatment on growth and psychomotor development in the DS subjects from the previous trial. Twelve of 15 adolescents with DS (3 F) from the GH group and 10 of 15 controls (5 F) participated in this follow-up study. Fifteen other subjects with DS (6 F) were included as controls in anthropometric analyses. Cognitive function was assessed with the Leiter International Performance Scale-Revised (Leiter-R) and selected subtests of the Wechsler Intelligence Scale for Children, Third edition (WISC-III). The Bruininks-Oseretsky Test of Motor Proficiency, Second edition (BOT-2), was used to assess general motor ability. Although early GH treatment had no effect on final height, the treated subjects had a greater head circumference standard deviation score (SDS) than the controls (-1.6 SDS vs. -2.2 SDS). The adolescents previously treated with GH had scores above those of the controls in all subtests of Leiter-R and WISC-III, but no difference in Brief IQ-score was seen between the groups. The age-adjusted motor performance of all subjects was below -2 SD, but the GH-treated subjects performed better than the controls in all but one subtest. The combined finding of a greater head circumference SDS and better psychomotor performance indicates that DS subjects may benefit from early GH treatment.

To evaluate the utility of Insulin-like growth factor I (IGF-I) standard deviation score (SDS) as a surrogate marker of severity of hypopituitarism in adults with pituitary pathology. We performed a retrospective data analysis, including 269 consecutive patients with pituitary disease attending a tertiary endocrine clinic in 1990-2015. The medical files were reviewed for the complete pituitary hormone profile, including IGF-I, and clinical data. Age-adjusted assay reference ranges of IGF-I were used to calculate IGF-I SDS for each patient. The main outcome measures were positive and negative predictive values of low and high IGF-I SDS, respectively, for the various pituitary hormone deficiencies. IGF-I SDS correlated negatively with the number of altered pituitary axes (p < 0.001). Gonadotropin was affected in 76.6 % of cases, followed by thyrotropin (58.4 %), corticotropin (49.1 %), and prolactin (22.7 %). Positive and negative predictive values yielded a clear trend for the probability of low/high IGF-I SDS for all affected pituitary axes. Rates of diabetes insipidus correlated with IGF-I SDS values both for the full study population, and specifically for patients with non-functioning pituitary adenomas. IGF-I SDS can be used to evaluate the somatotroph function, as a valid substitute to absolute IGF-I levels. Moreover, IGF-I SDS predicted the extent of hypopituitarism in adults with pituitary disease, and thus can serve as a marker of hypopituitarism severity.

Allostatic load (AL) is the cumulative physiological wear and tear that results from repeated efforts to adapt to stressors over time. The life stress response is modified by nutritional status. We estimated AL scores among neurologically impaired (NI) children; the association with malnutrition was also evaluated. Forty-one patients with severe disabilities were included. Data based on 15 biomarkers were used to create the AL score. A dichotomous outcome of high AL was defined for those who had ≥6 dysregulated components. Body mass index (BMI)-standard deviation score (SDS) <-2 or SDS ≥2 and biochemical markers (≥4) defined malnutrition. High AL was noted in 17/41 of the whole sample (41.47%). Malnutrition occurred in 36.6% of the subjects. A significant correlation between high AL and malnutrition was observed (p = 0.01; ar ea under the receiver operating characteristic curve, 0.7457). High AL subjects had a significantly higher BMI (p = 0.009) and lower BMI-SDS (p = 0.003) than low AL subjects. AL score correlated with fat mass (p ≤ 0.01) and negatively correlated with fat-free mass (p ≤ 0.02). In NI children, high AL was associated with malnutrition. Body composition is a better indicator than BMI of allostatic adjustments. AL estimation should be considered a measure of health risk and be used to promote quality of life in at-risk disabled populations. © 2017 S. Karger AG, Basel.

Objective The present study investigates the clinical interpretability of the Pediatric Quality of Life Inventory™ (PedsQL™) Gastrointestinal Symptoms Scales and Worry Scales in pediatric patients with functional gastrointestinal disorders or organic gastrointestinal diseases in comparison with healthy controls. Methods The PedsQL™ Gastrointestinal Scales were completed by 587 patients with gastrointestinal disorders/diseases and 685 parents, and 513 healthy children and 337 parents. Minimal important difference (MID) scores were derived from the standard error of measurement (SEM). Cut-points were derived based on one and two standard deviations (SDs) from the healthy reference means. Results The percentages of patients below the scales’ cut-points were significantly greater than the healthy controls (most p values ≤ .001). Scale scores 2 SDs from the healthy reference means were within the range of scores for pediatric patients with a gastrointestinal disorder. MID values were generated using the SEM. Conclusions The findings support the clinical interpretability of the new PedsQL™ Gastrointestinal Symptoms Scales and Worry Scales. PMID:25682210

Psychostimulants: Influence on Body Mass Index and Height in a Pediatric Population with Attention-Deficit/Hyperactivity Disorder?

Attention-deficit/hyperactivity disorder (ADHD) is often treated with psychostimulants. Psychostimulants' adverse effects on body mass index standard deviation score (BMI-sds) and height in children/adolescents with ADHD have been reported. However, literature is inconsistent, and it is unclear whether the observed effects are dosage- and/or BMI-dependent. Therefore, the aim of this retrospective observational study is to evaluate the influence of psychostimulants on BMI-sds and height-sds in a pediatric cohort with ADHD from an outpatient clinic, and to study the correlation between psychostimulant dosage and BMI-sds and height-sds change. Participants ≤18 years of age diagnosed with ADHD who started with psychostimulants (methylphenidate) were studied. Changes in BMI-sds and height-sds over an 18-month treatment period were assessed in subgroups according to baseline BMI-sds, gender, and age. Furthermore, correlations between BMI-sds, height-sds, and psychostimulant dose were studied. In total, 298 participants [median age 9.8 years, height-sds 0.0, BMI-sds 0.5, psychostimulant dosage 0.5 (0.2-1.4) mg/kg/day] were analyzed, with an underweight, overweight, and obesity prevalence of 5%, 21%, and 7%, respectively. After 18 months of treatment a significant decline in BMI-sds (-0.4) and height-sds (-0.2) was observed. These effects were consistent in all subgroups except for no change in BMI-sds in the underweight subgroup and no change in height-sds in the overweight subgroup. Medication dosage was weakly correlated with change in BMI-sds [r = -0.3 (-0.9 to +0.5); p < 0.01] and height-sds [r = -0.2 (-0.4 to -0.1); p = 0.01]. After 18 months of psychostimulant treatment, a significant decline in BMI-sds and height-sds was observed. However, the correlation with psychostimulant dosage was weak, and the decline was not observed in all subgroups. Therefore, further studies on the etiology of BMI-change are warranted, particularly with regard to the ADHD symptoms.

Weight-based GH dosing results in a wide variation in growth response in children with GH deficiency (GHD) or idiopathic short stature (ISS). The hypothesis tested was whether individualized GH doses, based on variation in GH responsiveness estimated by a prediction model, reduced variability in growth response around a set height target compared with a standardized weight-based dose. A total of 153 short prepubertal children diagnosed with isolated GHD or ISS (n = 43) and at least 1 SD score (SDS) below midparental height SDS (MPH(SDS)) were included in this 2-yr multicenter study. The children were randomized to either a standard (43 microg/kg.d) or individualized (17-100 microg/kg.d) GH dose. We measured the deviation of height(SDS) from individual MPH(SDS) (diffMPH(SDS)). The primary endpoint was the difference in the range of diffMPH(SDS) between the two groups. The diffMPH(SDS) range was reduced by 32% in the individualized-dose group relative to the standard-dose group (P < 0.003), whereas the mean diffMPH(SDS) was equal: -0.42 +/- 0.46 and -0.48 +/- 0.67, respectively. Gain in height(SDS) 0-2 yr was equal for the GH-deficient and ISS groups: 1.31 +/- 0.47 and 1.36 +/- 0.47, respectively, when ISS was classified on the basis of maximum GH peak on the arginine-insulin tolerance test or 24-h profile. Individualized GH doses during catch-up growth significantly reduce the proportion of unexpectedly good and poor responders around a predefined individual growth target and result in equal growth responses in children with GHD and ISS.

Obesity and its related factors are known to suppress the secretion of growth hormone (GH). We aimed to evaluate the influence of body mass index (BMI) on the peak GH response to provocative testing in short children without GH deficiency. We conducted a retrospective review of medical records of 88 children (2-15 yr old) whose height was less than 3 percentile for one's age and sex, with normal results (peak GH level > 10 ng/mL) of GH provocative testing with clonidine and dopamine. Peak stimulated GH level, height, weight, pubertal status and serum IGF-1 level were measured. Univariate analysis showed that the BMI standard deviation score (SDS) correlated negatively with the natural log (ln) of the peak stimulated GH level (ln peak GH). BMI SDS did not correlate significantly with sex, age, pubertal status, or ln IGF-1 level. BMI SDS correlated negatively with ln peak GH level induced by clonidine but not by dopamine. In stepwise multivariate regression analysis, BMI SDS was the only significant predictor of ln peak GH level in the combination of tests and the clonidine test, but not in the dopamine test. In children without GH deficiency, BMI SDS correlates negatively with the peak GH level. BMI SDS should be included in the analysis of the results of GH provocation tests, especially tests with clonidine.

This study evaluated renal swelling in infants with a first urinary tract infection (UTI) by correlating renal length and volume with C-reactive protein (CRP) and body temperature. Ultrasounds were carried out on 104 infants at The Queen Silvia Children's Hospital, Gothenburg, Sweden - 58 boys (mean age 3.3 months) and 46 girls (mean age 4.8 months) - during the acute phase of their UTI. A second scan was performed on 94 of them 4 weeks later. Renal length and volume were computed to standard deviation scores (SDS). The mean renal length and volume at the first ultrasound were 1.90 SDS (±1.54) and 1.67 SDS (±1.13) for the larger kidney and 0.86 SDS (±1.01) and 0.84 SDS (±0.90) for the smaller kidney. There was a significant decrease in renal length and volume between the two ultrasounds, with a mean difference of 0.96 SDS (±1.24) and 1.07 SDS (±1.10) for the larger kidney (p < 0.0001). The length and volume of the larger kidney correlated with CRP (p < 0.001), but only the renal length correlated with fever (p < 0.001). Early ultrasound determined renal swelling in infants with a UTI and may be a valuable noninvasive way of identifying infants with renal parenchymal involvement. ©2017 Foundation Acta Paediatrica.

To estimate health-related quality of life (HRQoL) in non-growth hormone deficient (GHD) small for gestational age (SGA) children before and after growth hormone (GH) treatment to adult height (AH). This was a multicentre, two-arm trial. Following an initial 2-year double-blind study period, patients entered a 2-year extension period followed by treatment to AH. At baseline patients were randomised to GH (0.033 or 0.067 mg/kg/day) and continued treatment at that dose until AH. Height was assessed at baseline and 3-monthly intervals to AH (height velocity <2 cm/year). Height standard deviation score (SDS) before and after GH therapy was mapped onto estimated HRQoL scores up to AH. Of the 79 children randomised into the study 53 were non-GHD (defined as peak GH >20 mU/L [peak 24-h GH value and peak arginine tolerance test]). At baseline these children had a mean (mean [+/-SD]) height SDS of -3.2 (0.7), height velocity SDS -0.6 (1.2) and age, 8.1 (1.9) years. Estimated HRQoL scores were significantly (p < 0.001) increased from baseline at AH (ΔHRQoL, 95% CI) (0.033 mg/kg/day, 0.112 [0.092, 0.132]; 0.067 mg/kg/day, 0.115 [0.094, 0.136]). HRQoL was not different between treatment groups. A significant gain in AH, relative to an SGA reference population, was reported in GH-treated patients. Mean (95% CI) ΔAH SDS (0.033 mg/kg/day, +1.4 [1.1, 1.6]. 0.067 mg/kg/day, +1.7[1.4, 2.0]). The analysis assumes HRQoL can be mapped onto height SDS. GH treatment in short children born SGA without signs of persistent catch-up growth was associated with significant improvement in HRQoL and normalisation of AH.

The objective was to examine longitudinal 4-year-relationships between neighbourhood social environment and children's body mass index-standard deviation score (BMI-SDS) taking into account the built environment. Furthermore, we have analysed the influence of potential interactions between the social environment and family/social data on children's BMI-SDS. Between 2006-2008 and 2010-2012, anthropometric measurements were conducted among 485 children (age at baseline: 6.1 (5.8-6.4)). Socio-demographic characteristics and perception of residential environment were reported by parents. Geographic Information Systems were used to examine street length, number of food outlets and distance to the nearest playground and park/green space within an 800 m Euclidian buffer of each participant address point. Additional data on neighbourhood characteristics (e.g., traffic density, walkability, crime rates) were obtained from the State Capital of Kiel, Germany. In a multivariate model, walkability, street type, socioeconomic status of the district and perceived frequency of passing trucks/buses were associated with BMI-SDS over 4 years, but only neighbourhood SES had an effect on change in BMI-SDS. However, familial/social factors rather than neighbourhood environment (especially social environment) had an impact on children's BMI-SDS over 4 years. Thus, social inequalities in childhood overweight are only partially explained by social neighbourhood environment.

Children with active inflammatory bowel disease (IBD) are frequently underweight. Anti-tumor necrosis factor (anti-TNF) agents may induce remission and restore growth. However, its use in other autoimmune diseases has been associated with excess weight gain. Our aim was to examine whether children with IBD could experience excess weight gain. A centralized diagnostic index identified pediatric IBD patients evaluated at our institution who received anti-TNF therapy for at least 1 year between August 1998 and December 2013. Anthropometric data were collected at time of anti-TNF initiation and annually. Excess weight gain was defined as ΔBMI SDS (standard deviation score) where patients were (1) reclassified from "normal" to "overweight/obese," (2) "overweight" to "obese," or (2) a final BMI SDS >0 and ΔSDS >0.5. During the study period, 268 children received anti-TNF therapy. Of these, 69 had sufficient follow-up for a median of 29.3 months. Median age at first anti-TNF dose was 12.8 years. At baseline, mean weight SDS was -0.7 (SD 1.4), while mean BMI SDS was -0.6 (1.3). Using baseline BMI SDS, 11.6% were overweight/obese. At last follow-up (LFU), however, the mean ΔBMI SDS was 0.50 (p < 0.0001). However, 10 (17%) patients had excess weight gain at LFU; 3 patients were reclassified from "normal" to "obese," and 7 had a final BMI SDS >0 and ΔSDS >0.5. Pediatric patients with IBD may experience excess weight gain when treated with anti-TNF agents. Monitoring for this side effect is warranted.

To explore the personality-adjusting effect of electro-acupuncture treatment for depression and compared this treatment with paroxetine treatment. A non-blinded, randomized controlled trial was adopted. Sixty depressed patients, who met trial criteria, were randomly assigned to the treatment and the control groups. In the treatment group, electro-acupuncture treatment was used, and paroxetine treatment was used in the control group. During the 24-week study period, 12 patients dropped out and 48 patients completed the study. The Minnesota Multiple Personality Inventory (MMPI) was adopted as the evaluation tool. At the same time, the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Montgomery-Asberg Depression Rating Scale (MADRS) were used to evaluate the psychological state. Evaluations were done before and after treatment. After treatment, patients' psychological state improved significantly in both groups (P<0.01). For the treatment group, within-group comparison between baseline and after 24 weeks of treatment showed that severity of depression had significantly decreased (P<0.01). MADRS and SDS scores decreased significantly (P<0.05) and MMPI subscale scores for hypochondriasis, depression, psychopathic deviate, psychasthenia, social introversion and fake decreased significantly (P<0.05). For the control group, severity of depression also decreased significantly. MADRS and SDS scores decreased significantly (P<0.05); and MMPI subscale scores for hypochondriasis, depression, hysteria, paranoia, and psychasthenia decreased significantly (P<0.05). Between-group comparison demonstrated that for the MMPI subscales paranoia and social introversion, the decrease of score was greater in the treatment group than in the control group (P<0.05). However, there were no other significant differences between the control group and the treatment group. Electro-acupuncture is effective for treating depression and affects personality traits.

Growth hormone (GH) is the most frequently used treatment in children with idiopathic short stature (ISS). Aromatase inhibitor (AI) therapy is still in an experimental state, and both final height (FH) and long-term efficacy data in ISS have not been published. We present a 14.5-year-old boy with ISS and a height of 142.7 cm [standard deviation score (SDS) -2.79]. Based on the baseline bone age (BA) of 13.5-14 years, his predicted adult height (PAH) by Bayley/Pinneau was 154 cm (SDS -3.77)-158.2 (SDS -3.15). After a 5-year letrozole monotherapy, FH was 169 cm (SDS -1.57) showing a height difference between PAH and FH from 10.8 to 15 cm. No permanent side effects of the medication have been observed. Both a transient occurrence and a spontaneous recovery of decreased bone mineral apparent density were seen, verified by dual-energy X-ray absorptiometry. Spinal magnetic resonance imaging revealed no vertebral abnormalities. All therapy might be an effective and low-cost alternative to the use of GH. Further controlled trials should prove efficacy and safety of long-term AI therapy in boys with ISS.

Nutritional status provides helpful information of disease severity and treatment effectiveness. Body mass index standard deviation scores (BMI-SDS) provide an approximation of body composition and thus are frequently used to classify nutritional status of sick children and adolescents. However, the accuracy of estimating body composition in this population using BMI-SDS has not been assessed. Thus, this study aims to evaluate the accuracy of nutritional status classification in sick infants and adolescents using BMI-SDS, upon comparison to classification using percentage body fat (%BF) reference charts. BMI-SDS was calculated from anthropometric measurements and %BF was measured using dual-energy x-ray absorptiometry (DXA) for 393 sick children and adolescents (5 months-18 years). Subjects were classified by nutritional status (underweight, normal weight, overweight, and obese), using 2 methods: (1) BMI-SDS, based on age- and gender-specific percentiles, and (2) %BF reference charts (standard). Linear regression and a correlation analysis were conducted to compare agreement between both methods of nutritional status classification. %BF reference value comparisons were also made between 3 independent sources based on German, Canadian, and American study populations. Correlation between nutritional status classification by BMI-SDS and %BF agreed moderately (r (2) = 0.75, 0.76 in boys and girls, respectively). The misclassification of nutritional status in sick children and adolescents using BMI-SDS was 27% when using German %BF references. Similar rates observed when using Canadian and American %BF references (24% and 23%, respectively). Using BMI-SDS to determine nutritional status in a sick population is not considered an appropriate clinical tool for identifying individual underweight or overweight children or adolescents. However, BMI-SDS may be appropriate for longitudinal measurements or for screening purposes in large field studies. When accurate nutritional status classification of a sick patient is needed for clinical purposes, nutritional status will be assessed more accurately using methods that accurately measure %BF, such as DXA.

The diagnosis of sarcoidosis is made by the combination of clinical features and biopsy results. The clinical features of sarcoidosis can be quite variable. We developed a Sarcoidosis Diagnostic Score (SDS) to summarize the clinical features of possible sarcoidosis patients. Biopsy confirmed sarcoidosis patients seen during a seven-month time period at the University of Cincinnati Sarcoidosis clinic were prospectively identified. Non-sarcoidosis patients seen at the same clinic were used as controls. Using a modified WASOG organ assessment instrument, we scored all patients for presence of biopsy, one or more highly probable symptom, and one or more at least probable symptom for each area. Two sarcoidosis scores were generated: SDS biopsy (with biopsy) and SDS clinical (without biopsy). The 980 evaluable patients were divided into two cohorts: an initial 600 patients (450 biopsy confirmed sarcoidosis, 150 controls) to establish cut-off values for SDS biopsy and SDS clinical and a validation cohort of 380 patients (103 biopsy confirmed sarcoidosis patients and 277 controls). The best cutoff value for SDS biopsy was > 6 (sensitivity =99.3%; specificity=100%). For the total the 980 patients, an SDS clinical > 3 had a sensitivity of 94.2%, specificity of 88.8%, and a likelihood ratio of 7.9. An SDS clinical score > 4 had a lower sensitivity of (76.9%) but higher specificity (98.6%). For sarcoidosis, the presence of specific clinical features, especially multi-organ involvement, can enhance the diagnostic certainty. The SDS scoring system quantitated the clinical features consistent with sarcoidosis. Copyright © 2018. Published by Elsevier Inc.

An examination of the effects of up to 260 weeks of growth hormone (GH) therapy on metabolic parameters in Japanese children born small for gestational age (SGA). Data were analysed from a 156-week extension of a 104-week multicentre, randomised, double-blind, parallel-group trial. Sixty-five children born SGA (age 3-<8 years) received 33 μg/kg/day (n = 31, 64.5% male) or 67 μg/kg/day (n = 34, 58.8% male) GH for 260 weeks. Changes in metabolic parameters - glucose, insulin, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol - were recorded. Alterations in weight, body mass index standard deviation score (BMI SDS) and vital signs were also evaluated. Over 260 weeks of GH treatment, a positive correlation between Δheight SDS and Δinsulin-like growth factor-I SDS was observed. Insulin and glucose levels were generally unaffected. Favourable changes in lipid profiles were recorded, which were maintained for the study duration. No adverse alterations in weight, BMI SDS or vital signs were noted. Long-term, continuous GH treatment in children born SGA appears to be efficacious, associated with potential benefits for several metabolic parameters and associated with no long-term safety concerns.

The efficacy and safety of growth hormone therapy in children with noonan syndrome: a review of the evidence.

PubMed

Noonan, Jacqueline A; Kappelgaard, Anne-Marie

2015-01-01

Noonan syndrome is a genetic disorder associated with short stature. We reviewed 15 studies in which growth hormone (GH) therapy was used in children with Noonan syndrome. Data show consistent increases in mean height standard deviation score (SDS), with first-year changes of up to 1.26 SDS. Among studies reporting adult or near-adult height, GH therapy over 5-7 years resulted in adult height SDS from -0.6 to -2.1, with up to 60% of subjects in some studies achieving adult height within 1 SDS of mid-parental height. GH treatment results in an acceleration of bone age, likely reflecting normalization from the retarded bone age common in Noonan syndrome patients at the start of therapy. BMI is not affected by GH treatment, but favorable changes in fat mass and body composition are achievable. Longer-term studies and observational studies suggest a waning of the effect of GH therapy over time, as is seen in other GH-treated conditions, and early initiation of therapy and prepubertal status are important predictors of response. GH treatment does not appear to be associated with adverse cardiac or metabolic effects, and data on malignancy during GH treatment give no cause for concern, although they are limited. © 2014 S.

Prior studies have found that the patients with posttraumatic stress disorder (PTSD) have poorer performance on cognitive tests than patients without PTSD, but the underlying mechanisms remain unknown. We examined the association between PTSD and cognitive function in a large cohort and evaluated the role of potential biological and behavioral mediators. A cohort of 535 adult outpatients (≤ 65 years) without dementia, stroke, or other neurologic disorders was recruited from 2 Veterans Affairs medical centers between February 2008 and June 2010. PTSD was assessed with the Clinician Administered PTSD Scale (CAPS) using DSM-IV-TR criteria. Cognitive function tests included processing speed, Trails A and B, letter fluency, category fluency, and verbal learning and recognition. Linear regression was used to evaluate the association between PTSD and cognitive function test scores and to assess potential mediators of the association. For our analyses of PTSD and cognitive function, we combined 178 participants who met criteria for full PTSD and 18 who met criteria for partial PTSD and had a CAPS score > 40. After adjusting for demographics, these participants with PTSD scored significantly worse on processing speed (0.30 standard deviations [SDs], P ≤ .001), category fluency (0.23 SDs, P = .01), verbal learning (0.30 SDs, P = .001), and verbal recognition (0.18 SDs, P = .048) than those without PTSD. These associations were largely accounted for by health behaviors, vascular risk factors, and depression. In this cohort of veterans under age 65 years without known neurologic disease, patients with versus without PTSD had significantly poorer performance in several domains of cognitive function, particularly in tests involving processing speed, executive function, and learning. These cognitive deficits were largely explained by modifiable risk factors. Interventions targeted at these risk factors might minimize the impact of PTSD on cognitive decline and dementia risk as patients age. © Copyright 2013 Physicians Postgraduate Press, Inc.

The Great East Japan Earthquake followed by tsunamis and the Fukushima Daiichi Nuclear Power Plant (NPP) accident caused catastrophic damage. The effects of the disaster on the growth of affected children are of great concern but remain unknown. The subject group was derived from two Japanese nationwide retrospective cohorts (historical control and exposure groups, respectively). The exposure group experienced the disaster at 47-59 months of age. We analyzed longitudinal changes in standard deviation score (SDS) for height and body mass index (BMI) using normal Japanese children's standards. Moreover, we analyzed the details of the affected children in Fukushima using Fukushima-specific growth charts established with the historical control data to clarify any indirect effect of the disaster on growth. Affected children in Fukushima had significantly higher BMI SDS than the historical control group (difference, 0.13; 95% CI: 0.044-0.21, P = 0.0029) and the regional controls (difference, 0.14; 95% CI: 0.074-0.20, P < 0.0001) 1.5 years after the disaster. Similar sustained increases in BMI SDS were also found with Fukushima-specific growth charts, but the phenomenon was detected only in boys. Notably, the BMI SDS of affected children who lived near the NPP had been increasing after the disaster, whereas those in distant areas had not changed. In contrast, height SDS had not changed throughout the analysis. Prolonged elevated BMI SDS was detected only in affected children in Fukushima. This phenomenon may be explained by an indirect effect of the NPP accident. © 2017 Japan Pediatric Society.

Leri-Weill syndrome (LWS) is a skeletal dysplasia with mesomelic short stature, bilateral Madelung deformity (BMD) and SHOX (short stature homeobox-containing gene) haploinsufficiency. The effect of 24 months of recombinant human growth hormone (rhGH) therapy on the stature and BMD of two females with SHOX haploinsufficiency (demonstrated by fluorescence in situ hybridisation) and LWS was evaluated. Both patients demonstrated an increase in height standard deviation score (SDS) and height velocity SDS over the 24 months of therapy. Patient 1 demonstrated a relative increase in arm-span and upper segment measurements with rhGH while patient 2 demonstrated a relative increase in lower limb length. There was appropriate advancement of bone age, no adverse events and no significant deterioration in BMD. In this study, 24 months of rhGH was a safe and effective therapy for the disproportionate short stature of SHOX haploinsufficiency, with no clinical deterioration of BMD.

In order to evaluate the social cognitive functioning in children with Prader-Willi syndrome (PWS), Theory of Mind (ToM) and symptoms of Autism Spectrum Disorder were evaluated. Sixty-six children with PWS aged 7-17 years were tested using the Theory of Mind test-R and the Diagnostic Interview for Social Communication disorders. We tested the correlation between Total ToM Standard Deviation Score (Total ToM SDS) and genetic subtype of paternal deletion or maternal uniparental disomy, and total IQ, verbal IQ and performal IQ. Prevalence and symptoms of Autism Spectrum Disorder were assessed. Median (interquartile range) of total ToM SDS of those aged 7-17 years was -3.84 (-5.73, -1.57). Their Total ToM SDS correlated with total IQ (β=0.662, p<0.001, adj.R(2)=0.407), in particular with verbal IQ (β=0.502, p=0.001, adj.R(2)=0.409), but not with performal IQ (β=0.241, p>0.05, adj.R(2)=0.259). No difference in Total ToM SDS was found between children with deletion and maternal uniparental disomy (β=-0.143, p>0.05, adj.R(2)=-0.016). Compared to the reference group of healthy children aged 7-12 years, children with PWS in the same age group had a median ToM developmental delay of 4 (3-5) years. One third of children with PWS scored positive for Autism Spectrum Disorder. Most prominent aberrations in Autism Spectrum Disorder were focused on maladaptive behavior. Our findings demonstrate a markedly reduced level of social cognitive functioning, which has consequences for the approach of children with PWS, i.e. adjustment to the child's level of social cognitive functioning.

The body mass index (BMI) standard deviation score (SDS) may not adequately reflect changes in fat mass during childhood obesity treatment. This study aimed to investigate associations between BMI SDS, body composition, and fasting plasma lipid concentrations at baseline and during childhood obesity treatment. 876 children and adolescents (498 girls) with overweight/obesity, median age 11.2 years (range 1.6-21.7), and median BMI SDS 2.8 (range 1.3-5.7) were enrolled in a multidisciplinary outpatient treatment program and followed for a median of 1.8 years (range 0.4-7.4). Height and weight, body composition measured by dual-energy X-ray absorptiometry, and fasting plasma lipid concentrations were assessed at baseline and at follow-up. Lipid concentrations (total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), non-HDL, and triglycerides (TG)) were available in 469 individuals (264 girls). Linear regressions were performed to investigate the associations between BMI SDS, body composition indices, and lipid concentrations. At baseline, BMI SDS was negatively associated with concentrations of HDL (p = 6.7*10-4) and positively with TG (p = 9.7*10-6). Reductions in BMI SDS were associated with reductions in total body fat percentage (p<2*10-16) and percent truncal body fat (p<2*10-16). Furthermore, reductions in BMI SDS were associated with improvements in concentrations of TC, LDL, HDL, non-HDL, LDL/HDL-ratio, and TG (all p <0.0001). Changes in body fat percentage seemed to mediate the changes in plasma concentrations of TC, LDL, and non-HDL, but could not alone explain the changes in HDL, LDL/HDL-ratio or TG. Among 81 individuals with available lipid concentrations, who increased their BMI SDS, 61% improved their body composition, and 80% improved their lipid concentrations. Reductions in the degree of obesity during multidisciplinary childhood obesity treatment are accompanied by improvements in body composition and fasting plasma lipid concentrations. Even in individuals increasing their BMI SDS, body composition and lipid concentrations may improve.

Objective The body mass index (BMI) standard deviation score (SDS) may not adequately reflect changes in fat mass during childhood obesity treatment. This study aimed to investigate associations between BMI SDS, body composition, and fasting plasma lipid concentrations at baseline and during childhood obesity treatment. Methods 876 children and adolescents (498 girls) with overweight/obesity, median age 11.2 years (range 1.6–21.7), and median BMI SDS 2.8 (range 1.3–5.7) were enrolled in a multidisciplinary outpatient treatment program and followed for a median of 1.8 years (range 0.4–7.4).

Although short children who were born small for gestational age (SGA) seem to have normal body proportions, objective data both before and during growth hormone (GH) treatment are very limited. Therefore, we investigated in a large group of short children who were born SGA the effects of GH treatment versus no treatment on head circumference (HC) and body proportions. Furthermore, we studied differences in linear growth and HC between SGA children who were born with a low birth length and birth weight (SGA(L+W)) and SGA children who were born with a low birth length only (SGA(L)). An open-labeled, GH-controlled, multicenter study was conducted for 3 years. Non-GH-deficient short SGA children (n = 87), with a mean age (standard deviation) of 5.9 (1.5) years, were randomized to either a GH group (n = 61), receiving GH in a dose of 33 microg/kg/day, or an untreated control group (n = 26). Height; weight; HC; sitting height; armspan; and hand, tibial, and foot size were measured and expressed as standard deviation score (SDS) adjusting for gender and age. At baseline, all anthropometric measurements, except HC SDS, were significantly lower compared with -2 SDS. During GH treatment, all anthropometric measurements normalized in accordance to the normalization of height SDS. At the start of the study, mean HC SDS was significantly lower in SGA(L+W) children compared with SGA(L) children. It is interesting that most (14 of 16) children with an HC SDS less than -2.00 had been born SGA(L+W). During GH treatment, the 3-year increase in height, HC, and other anthropometric measurements was comparable between SGA(L+W) and SGA(L) children. In both SGA(L+W) and SGA(L) control subjects, no changes in SDSs of height, HC, and other anthropometric measurements were found during the 3-year follow-up period. Untreated short SGA children have normal body proportions with the exception of HC, which is relatively large in many of these children. SGA(L+W) children still had a smaller HC at the age of 5.9 years compared with SGA(L) children. Three years of GH treatment induced a proportionate growth resulting in a normalization of height and other anthropometric measurements, including HC, in contrast to untreated SGA control subjects.

Inflammation contributes to growth failure associated with inflammatory bowel diseases. Anti-TNFα therapy induces sustained remission and short-term improvements in height velocity and/or height standard deviation score (H-SDS) patients with Crohn's disease. The purpose of this study was to evaluate growth and adult height in patients with Crohn's disease taking maintenance infliximab or adalimumab therapy.This university-hospital based retrospective study included 61 patients, with a median follow-up of 2.6 years (2.0; 3.3). 38 patients (62%) reached their adult height. H-SDS was collected at diagnosis and together with disease activity markers (Harvey-Bradshaw Index, albumin, and C-reactive protein) at treatment initiation (baseline), and follow-up completion. Wilcoxon's signed-rank test was chosen for comparisons. Median H-SDS decreased from diagnosis to baseline (-0.08 [-0.73; +0.77] to -0.94 [-1.44; +0.11], p<0.0001) and then increased to follow-up completion (-0.63 [-1.08; 0.49], p = 0.003 versus baseline), concomitantly with an improvement in disease activity. Median adult H-SDS was within the normal range (-0.72 [-1.25; +0.42]) but did not differ from baseline H-SDS and was significantly lower than the target H-SDS (-0.09 [-0.67; +0.42], p = 0.01). Only 2 (6%) males had adult heights significantly below their target heights (10.5 and -13.5 cm [-1.75 and -2.25 SD]). In conclusion, anti-tumor necrosis factor α (TNF) therapy prevented loss of height without fully restoring the genetic growth potential in this group of patients with CD. Earlier treatment initiation might improve growth outcomes in these patients.

Elite male artistic gymnasts (AG) are exposed to high levels of physical and psychological stress during adolescence and experience a significant late maturation in both linear growth and pubertal development. The aim of the present study was to determine the impact of intensive physical training on the adult final height in elite male AG. This study is unique in character, as all variables were measured on the field of competition. The study was prospective and longitudinal; however, the current analysis of data is cross-sectional. Data from 86 elite male AG were obtained during the gymnastics competitions of European and World Championships. Clinical evaluation included height and weight measurements, as well as assessment of pubic hair and genital development according to Tanner's stages of pubertal development. The laboratory investigation included determination of skeletal maturation. All athletes completed a questionnaire that included questions on personal (onset and intensity of training, number of competitions per year) and family data (paternal and maternal heights). Male AG were below the 50th percentile for both final height and weight. Elite male AG had final height standard deviation score (SDS) lower than their genetic predisposition. Final height SDS was correlated positively with target height SDS (r = 0.430, p < 0.001) and weight SDS (r = 0.477, p < 0.001) and negatively to the intensity of training (r = -0.252, p = 0.022). The main factors influencing final height, by multiple regression analysis were weight SDS (p < 0.001) and target height SDS (p = 0.003). In elite maleAG, final height falls short of genetic predisposition, still well within normal limits. Considering medical and psychological risks in general, and based on the results of this research project, the International Federation of Gymnastics has increased the age limit for participants in international gymnastics competitions by 1 year.

Increased consumption of sweetened beverages has previously been linked to the degree of childhood obesity. The aim of the present study was to assess whether the intake of sweetened beverages, candy, snacks or fast food at baseline in a multidisciplinary childhood obesity treatment program was associated with the baseline degree of obesity or the treatment effect. This prospective study included 1349 overweight and obese children (body mass index standard deviation scores (BMI SDS) ≥ 1.64) enrolled in treatment at The Children's Obesity Clinic, Copenhagen University Hospital Holbaek. The children were evaluated at baseline and after up to 5.9 years of treatment (median 1.3 years). Both boys and girls decreased their BMI SDS during treatment with a mean decrease in boys of 0.35 (p < 0.0001) and in girls of 0.22 (p < 0.0001) after 1 year of treatment. There were no associations between the baseline intake of sweetened beverages, candy, snacks, and/or fast food and BMI SDS at baseline or the change in BMI SDS during treatment. The intake of sweetened beverages, candy, snacks or fast food when entering a childhood obesity treatment program was not associated with the degree of obesity at baseline or the degree of weight loss during treatment. © 2016 World Obesity Federation.

Decreased growth velocity and abnormal body composition including severe osteoporosis are common in glucocorticoid-treated patients with juvenile idiopathic arthritis (JIA). We evaluated the effects of recombinant human growth hormone (GH) given for 3 years on growth velocity, height standard deviation score (SDS), and body composition, together with potential adverse effects on glucose tolerance. Thirteen patients received GH (0.46 mg/kg/week) for 3 years. Body composition was assessed by dual-energy x-ray absorptiometry and glucose tolerance by annual oral glucose tolerance tests. Median growth velocity increased from 2.1 to 6.0 cm/year (p = 0.002) in the first year and remained higher than baseline in the second year of treatment. Height SDS did not change significantly (-4.6 SDS at baseline vs -4.3 SDS at study completion), but the growth response varied markedly across patients. Compared with baseline, lean mass increased by 33%, fat mass remained stable, and lumbar bone mineral density increased by 36.6%. Transient glucose intolerance developed in 6 patients, but glycosylated hemoglobin concentrations did not change significantly and diabetes mellitus did not occur. Treatment with GH restored linear growth without inducing catch-up growth, significantly improved body composition, and prevented further bone loss. Prolonged followup is needed to assess the benefits of GH and longterm consequences of hyperinsulinism.

The incidence of postoperative nausea and vomiting (PONV) can be reduced by dexamethasone. Single-dose administration may cause elevated blood glucose levels in obese adults. No data are available for children. The aim was to evaluate perioperative blood glucose changes related to body weight in children who received dexamethasone. This prospective observational study included 62 children. All patients received total intravenous anesthesia and a single dose of dexamethasone (0.15 mg/kg, maximum 8 mg). Blood glucose levels were measured up to 6 h. Standard deviation scores (SDS) were calculated using age- and gender-specific body mass index (BMI) percentiles, p<0.05. A total of 62 children (11.5±2.9 years, median SDS 0.43, 29% overweight/obese) were included. Blood glucose levels increased from 5.52±0.52 to 6.74±0.84 mmol/L 6 h after dexamethasone without correlation to the BMI-SDS. This study showed an increase of perioperative blood glucose (normoglycemic ranges) after single dose of dexamethasone, but no BMI-dependent effect was observed in children. Therefore, low-dose dexamethasone may be used in obese children for PONV prophylaxis.

To provide for early detection of abnormal changes in growth, we propose the monitoring of all children for changes in relative height and relative weight as indirect indicators of growth velocity. To this end we analyzed the growth of 2,156 children, as recorded by the child health surveillance services at ages 2 to 19 years. From their data we constructed growth standards on charts of a novel type, which allow direct reading of relative height (SD score, SDS) and relative weight (percentage deviation of weight from median weight for height and sex, %DW). Variation in height explained most (mean 60%) of the variation in weight, and age did not contribute significantly. Hence, our weight charts are height-based. Next, we defined the variations of changes in (delta) SDS and %DW during the different periods of growth. The group means of changes in each period were zero. Variation in delta SDS is widest at the earliest ages, then decreases until year 9-10 (girls) and 10-11 (boys), and again increases. For delta %DW the picture is similar. We present these variations as diagrams for use in growth screening.

Growth hormone (GH) therapy may improve statural growth outcomes in patients with severe juvenile idiopathic arthritis (JIA). To evaluate the effect of GH treatment on adult height and to identify determinants of growth outcomes in JIA. Data from 58 patients with JIA, including 53 receiving GH, enrolled in three prospective clinical trials between 1997 and 2002 were analyzed. GH (0.056 mg/kg/d [interquartile range (IQR), 0.050 to 0.062]) for a median duration of 6.5 years (IQR, 4.7 to 7.9 years). Factors associated with a favorable growth outcome (adult height - target height ≤ -1.5 standard deviations) were identified by multivariate logistic regression. Adult height was available for 48 patients 8.6 years after GH initiation (IQR, 6.0 to 10.2 years). Height standard deviation score (SDS) increased from -2.9 (IQR, -4.4 to -1.6) at baseline to -1.7 (IQR, -3.9 to -0.1) in adulthood (P < 0.001). Median adult height was below target height [SDS, -0.2 (IQR, -1.4 to 0.4); P < 0.001]. Corrected adult height SDS was -1.3 (IQR, -3.0 to -0.2). Growth outcome was favorable in 24 (52.2%) patients. Significant independent determinants of growth outcome were age at GH initiation [adjusted odds ratio (aOR), 0.68 per additional year; 95% confidence interval (CI), 0.47 to 0.99], height at GH initiation (aOR, 2.6 per additional SDS; 95% CI, 1.15 to 5.9), and mean C-reactive protein levels during follow up (aOR, 0.51 per additional 10 mg/L; 95% CI, 0.28 to 0.92). Long-term GH treatment significantly increased growth in patients with JIA but did not fully restore the genetic growth potential. The response showed marked interindividual variability and was weaker in patients with severe inflammation. Copyright © 2017 Endocrine Society

Long-term replacement treatment with high doses of steroids in congenital adrenal hyperplasia (CAH) is known to have a negative influence on growth. We evaluated the effects of long-term steroid treatment in patients with classical CAH on height development in relation to genetic height potential. Twenty-three patients with CAH (16 females, 7 males, mean age: 9.8 +/- 3.5 years) were included in this longitudinal study. The effect of steroid treatment on growth was determined by monitoring patients for 8.61 +/- 3.46 years (2-17 years) while they were treated with hydrocortisone at a mean dosage of 17.64 +/- 3.60 mg/m2/day. The height standard deviation scores (Ht-SDS), target Ht-SDS, and corrected Ht-SDS for target height was calculated for all patients. Predicted adult height according to bone age was calculated and it was determined whether height was developing according to the genetic height potential. In addition, patients were grouped as 'tight control' or 'poor control' according to their mean serum 17OH-progesterone or ACTH levels while on treatment. We evaluated whether height development was different for the tight and poor control groups. The mean chronological age of our patients at the time of the study was 9.89 +/- 3.53 years, Ht-SDS -0.77 +/- 1.57, target height (TH) 161.03 +/- 6.54 cm, TH-SDS -0.60 +/- 0.90, predicted height (PH) 157.2 +/- 11.16 cm, PH-SDS -1.1 +/- 1.69, and corrected Ht-SDS -0.75 +/- 1.14. There was no significant difference between the actual Ht-SDS and TH-SDS of our patients (p >0.05) but the corrected Ht-SDS was less than zero. Only 28.5% of our patients had normal height according to their genetic potential while 71.5% were shorter than their genetic height potential. While the Ht-SDS and corrected Ht-SDS were similar in the tight and poor metabolic control groups, the predicted height was significantly greater in the tight control group. We demonstrated that a hydrocortisone dose of 17.64 +/- 3.60 mg/m2/day in classical CAH had a negative influence on height development for genetic height potential in 8.5 years of follow-up and that it is necessary to use the lowest possible steroid dosage by individualizing the dose.

Gonadal dysgenesis with an apparently normal 46,XX karyotype is a rare cause of hypergonadotrophic hypogonadism. Tall stature is not a widely recognized association. A 15-year-old girl presented with primary amenorrhoea. Examination showed a non-dysmorphic girl of normal intellect with no breast development (Tanner stage B1P4A1) who was tall compared with her parents: height standard deviation score (SDS) +1.56 vs. midparental height of +0.23 SDS, and slim build (weight -0.13 SDS). Investigations showed a 46,XX karyotype, elevated gonadotropins (FSH 119 and LH 33.7 IU/L), serum estradiol <5 pmol/L, uterine length 3.75 cm with cylindrical shape, and absent ovaries on ultrasound. Initially, a 364055-bp deletion on Xp21.2 was reported on array CGH. However, repeat analysis using BlueGnome CytoChip ISCA 4x180k v2.0 array was normal. With oral ethinyl estradiol induction puberty progressed to B4P4A2 but aged 18.4 years, the patient was remarkably tall with height SDS +2.88, weight SDS +0.97. Caution is needed in interpreting small changes with array CGH, particularly with the older assays. We postulate that the genetic change causing 46,XX gonadal dysgenesis in our patient may have also resulted in unsuppressed somatic growth. More critical height assessment, including parental height measurement, of future patients with 46,XX gonadal dysgenesis is recommended in order to determine whether or not a true association with tall stature may be present in certain cases.

Neonatal hypernatremic dehydration is prevented by daily neonatal weight monitoring. We aim to provide evidence-based support of this universally promoted weighing policy and to establish the most crucial days of weighing. Weight measurements of 2,359 healthy newborns and of 271 newborns with clinical hypernatremic dehydration were used within the first seven days of life to simulate various weighting policies to prevent hypernatremic dehydration; its sensitivity, specificity and positive predictive value (PPV) of these policies were calculated. Various referral criteria were also evaluated. A policy of daily weighing with a cut-off value of -2.5 Standard Deviation Score (SDS) on the growth chart for weight loss, had a 97.6% sensitivity, 97.6% specificity and a PPV of 2.80%. Weighing at birth and only at days two, four and seven with the same -2.5 SDS cut-off, resulted in 97.3% sensitivity, 98.5% specificity and a PPV of 4.43%. A weighing policy with measurements restricted to birth and day two, four and seven applying the -2.5 SDS cut-off seems an optimal policy to detect hypernatremic dehydration. Therefore we recommend to preferably weigh newborns at least on day two (i.e. ~48h), four and seven, and refer them to clinical pediatric care if their weight loss increases below -2.5 SDS. We also suggest lactation support for the mother, full clinical assessment of the infant and weighing again the following day in all newborns reaching a weight loss below -2.0 SDS.

Objective There is a scarcity of data from randomised controlled trials on the association of growth hormone (GH) with gonadotrophin-releasing hormone agonists in idiopathic short stature (ISS), although this off-label use is common. We aimed to test whether delaying pubertal progression could increase near-adult height (NAH) in GH-treated patients with ISS. Methods Patients with ISS at puberty onset were randomised to GH with leuprorelin (combination, n = 46) or GH alone (n = 45). NAH standard deviation score (SDS) was the primary outcome measure. The French regulatory authority requested premature discontinuation of study treatments after approximately 2.4 years; patients from France were followed for safety. Results Mean (s.d.) baseline height SDS was −2.5 (0.5) in both groups, increasing at 2 years to −2.3 (0.6) with combination and −1.8 (0.7) with GH alone. NAH SDS was −1.8 (0.5) with combination (n = 19) and −1.9 (0.8) with GH alone (n = 16). Treatment-emergent adverse events and bone fractures occurred more frequently with combination than GH alone. Conclusion Due to premature discontinuation of treatments, statistical comparison of NAH SDS between the two cohorts was not possible. During the first 2–3 years of treatment, patients treated with the combination grew more slowly than those receiving GH alone. However, mean NAH SDS was similar in the two groups. No new GH-related safety concerns were revealed. A potentially deleterious effect of combined treatment on bone fracture incidence was identified. PMID:29669803

We report the case of a boy affected by severe intrauterine and postnatal growth retardation, microcephaly, facial dysmorphisms and postnecrotic cirrhosis, diagnosed at birth as having Seckel syndrome, and subsequently confirmed as Majewski osteodysplastic primordial dwarfism type II (MOPD II) on the basis of clinical and radiological features of skeletal dysplasia. At our observation (6 years 7 months) he presented height -10.3 standard deviation score (SDS), weight -22.1 SDS, head circumference -8 SDS, delayed bone age of 4 years with respect to chronological age. In consideration of the low levels of insulin-like growth factor-1 (IGF-1) as well as of hepatic insufficiency, we started the treatment with recombinant human IGF-1 (rhIGF-1) at the dose of 0.04 mg/kg in 2 doses/day, with an increase of 0.04 mg/kg after 1 week until the maximum dose of 0.12 mg/kg. We observed an early response to rhIGF-1 treatment, with a shift of height velocity from 1.8 cm/year (-4.6 SDS) at 4 cm/year (-1.9 SDS), and an increase in bone age of 1.5 years during the first 6 months. rhIGF-1 treatment does not seem to be able to replace the physiological action of IGF-1 in patients with MOPD II and hepatic insufficiency, however, it seems to preserve the typical growth pattern of MOPD II patients, avoiding a further widening of the growth deficiency in these subjects.

We compared functional impairment outcomes assessed with Sheehan Disability Scale (SDS) after treatment with duloxetine versus selective serotonin reuptake inhibitors (SSRIs) in patients with major depressive disorder. Data were pooled from four randomized studies comparing treatment with duloxetine and SSRIs (three double blind and one open label). Analysis of covariance, with last-observation-carried-forward approach for missing data, explored treatment differences between duloxetine and SSRIs on SDS changes during 8 to 12 weeks of acute treatment for the intent-to-treat population. Logistic regression analysis examined the predictive capacity of baseline patient characteristics for remission in functional impairment (SDS total score ≤ 6 and SDS item scores ≤ 2) at endpoint. Included were 2193 patients (duloxetine n = 1029; SSRIs n = 835; placebo n = 329). Treatment with duloxetine and SSRIs resulted in significantly (p < 0.01) greater improvements in the SDS total score versus treatment with placebo. Higher SDS (p < 0.0001) or 17-item Hamilton Depression Rating Scale baseline scores (p < 0.01) predicted lower probability of functional improvement after treatment with duloxetine or SSRIs. Female gender (p ≤ 0.05) predicted higher probability of functional improvement after treatment with duloxetine or SSRIs. Treatment with SSRIs and duloxetine improved functional impairment in patients with major depressive disorder. Higher SDS or 17-item Hamilton Depression Rating Scale baseline scores predicted less probability of SDS improvement; female gender predicted better improvement in functional impairment at endpoint. © 2015 The Authors.

The Australian Prader-Willi Syndrome (PWS) database was established to monitor the efficacy and safety of growth hormone (GH) treatment in PWS. This study aims to compare response to GH based on eligibility criteria. Comparative study: 72 children received GH on the basis of short stature or evidence of GH deficiency (pre-2009: PWS-SS) and 94 on a genetic diagnosis (post-2009: PWS-Dx). We report on mandatory patient data for GH prescription: median and standard deviation score (SDS) for height and body mass index (BMI), waist/height ratio, bone age/chronological age ratio and adverse events. Comparisons were made using non-parametric tests. At baseline, the PWS-SS cohort was shorter (height SDS: -2.6 vs. -1.1, P < 0.001), had a lower BMI (0.6 vs. 1.5 SDS, P < 0.05) and greater bone age delay (bone age/chronological age: 0.7 vs. 0.9, P < 0.05) than the PWS-Dx cohort. PWS-SS parents were shorter (mid-parental height SDS: -0.13 vs. 0.28, P < 0.005). Mean change in height over 2 years was 0.9 SDS and in BMI using PWS reference standards -0.3 SDSPWS (n = 106) (year 2, height SDS: PWS-SS = -1.7, PWS-Dx = 0.1; BMI SDSPWS : PWS-SS = -1.0, PWS-Dx = -0.6). The waist/height ratio reduced (PWS-Dx: 0.60 vs. 0.56, P < 0.05) and bone age delay was unchanged over this period. No serious adverse events were reported. The PWS-SS cohort represents a subgroup of the wider PWS-Dx population; however both cohorts improved height SDS with normalisation of height in the PWS-Dx cohort and lowering of BMI relative to PWS standards supporting the efficacy of treatment under the current Australian GH programme. © 2013 The Authors.

To evaluate the safety, local tolerability, pharmacodynamics and pharmacokinetics of escalating single doses of once-weekly somapacitan, a reversible, albumin-binding GH derivative, vs once-daily GH in children with GH deficiency (GHD). Phase 1, randomized, open-label, active-controlled, dose-escalation trial (NCT01973244). Thirty-two prepubertal GH-treated children with GHD were sequentially randomized 3:1 within each of four cohorts to a single dose of somapacitan (0.02, 0.04, 0.08 and 0.16 mg/kg; n=6 each), or once-daily Norditropin ® SimpleXx ® (0.03 mg/kg; n=2 each) for 7 days. Pharmacokinetic and pharmacodynamic profiles were assessed. Adverse events were all mild, and there were no apparent treatment-dependent patterns in type or frequency. Four mild transient injection site reactions were reported in three of 24 children treated with somapacitan. No antisomapacitan/anti-human growth hormone (hGH) antibodies were detected. Mean serum concentrations of somapacitan increased in a dose-dependent but nonlinear manner: maximum concentration ranged from 21.8 ng/mL (0.02 mg/kg dose) to 458.4 ng/mL (0.16 mg/kg dose). IGF-I and IGFBP-3, and change from baseline in IGF-I standard deviation score (SDS) and IGFBP-3 SDS, increased dose dependently; greatest changes in SDS values were seen for 0.16 mg/kg. IGF-I SDS values were between -2 and +2 SDS, except for peak IGF-I SDS with 0.08 mg/kg somapacitan. Postdosing, IGF-I SDS remained above baseline levels for at least 1 week. Single doses of once-weekly somapacitan (0.02-0.16 mg/kg) were well tolerated in children with GHD, with IGF-I profiles supporting a once-weekly treatment profile. No clinically significant safety/tolerability signals or immunogenicity concerns were identified. © 2017 The Authors. Clinical Endocrinology Published by John Wiley & Sons Ltd.

We examined the effect of a 12-week family-based cognitive behavioural weight management programme developed for use in primary care settings. The sample consisted of 49 children with obesity (aged 7-13 years; mean ± SD: 10.68 ± 1.24). Families were randomly assigned to immediate start-up of treatment or to a 12-week waiting list condition. Outcome measures were body mass index standard deviation score (BMI SDS), self-esteem, symptoms of depression and blood parameters indicative of cardio-metabolic risk. Assessments were conducted at baseline, post-treatment, post-waiting list and 12 months after treatment termination. The mean reduction for the treatment group was -0.16 BMI SDS units compared with an increase of 0.04 units for the waiting list group (p = .001). For the entire sample, there was a significant post-treatment improvement on BMI SDS (p = .001), all self-esteem measures (p = .001-.041) and symptoms of depression (p = .004). The mean BMI SDS reduction was -0.18 units post-treatment, and it was maintained at 12-month follow-up. Significant reductions were found in blood lipid levels of total cholesterol (p = .03), LDL-cholesterol (p = .005) and HDL-cholesterol (p = .01) at 12-month follow-up. The favourable effect on most of the psychological measures waned from post-treatment to follow-up, but not approaching baseline levels. Boys demonstrated significantly greater reductions in BMI SDS than girls (p = .001), while baseline psychiatric co-morbidity did not influence BMI SDS outcome. The treatment shows significant and favourable effects on BMI SDS, self-esteem and symptoms of depression compared with a waiting list condition. © 2013 Asian Oceanian Association for the Study of Obesity .

Due to the pandemic of child and adolescent overweight and obesity, improvements in overweight and obesity treatment availability and accessibility are needed. In this prospective study, we investigated if reductions in body mass index (BMI) standard deviation scores (SDS) and waist circumference (WC) would occur during 1.5 years of community-based overweight and obesity treatment based upon an effective hospital-based overweight and obesity treatment protocol, The Children's Obesity Clinics' Treatment protocol. Height, weight, and WC were measured at all consultations. Changes in BMI SDS and WC were analyzed using linear mixed models based upon the repeated measures in each child. From June 2012 to January 2015, 1,001 children (455 boys) were consecutively enrolled in the community-based treatment program. Upon entry, the median age was 11 years (range: 3-18), and the median BMI SDS was 2.85 (range: 1.26-8.96) in boys and 2.48 (range: 1.08-4.41) in girls. After 1.5 years of treatment BMI SDS was reduced in 74% of the children. BMI SDS was reduced by a mean of 0.38 (95% confidence interval (CI): 0.30-0.45, p<0.0001) in boys and 0.18 (95% CI: 0.12-0.25, p<0.0001) in girls after 1.5 years of treatment, independently of baseline age, BMI SDS, and Tanner stage (all p>0.08). WC was reduced by a mean of 3.8 cm (95% CI: 2.7-4.9, p>0.0001) in boys and 5.1 cm (95% CI: 4.0-6.2, p>0.0001) in girls. The dropout rate was 31% after 1.5 years. A median of 4.5 consultation hours was invested per child per year. BMI SDS and WC were reduced after 1.5 years of treatment. Hence, this community-based overweight and obesity treatment program may help accommodate the need for improvements in treatment availability and accessibility.

Outcome measures can be used to improve the quality of the rehabilitation by identifying and understanding which variables influence the outcome. This information can be used to improve outcomes for clients. In clinical practice, pure-tone audiometry, speech reception thresholds (SRTs), and speech discrimination scores (SDSs) in quiet or in noise are common assessments made prior to hearing aid (HA) fittings. It is not known whether SRT and SDS in quiet relate to HA outcome measured with the International Outcome Inventory for Hearing Aids (IOI-HA). The aim of the present study was to investigate the relationship between pure-tone average (PTA), SRT, and SDS in quiet and IOI-HA in both first-time and experienced HA users. SRT and SDS were measured in a sample of HA users who also responded to the IOI-HA. Fifty-eight Danish-speaking adult HA users. The psychometric properties were evaluated and compared to previous studies using the IOI-HA. The associations and differences between the outcome scores and a number of descriptive variables (age, gender, fitted monaurally/binaurally with HA, first-time/experienced HA users, years of HA use, time since last HA fitting, best ear PTA, best ear SRT, or best ear SDS) were examined. A multiple forward stepwise regression analysis was conducted using scores on the separate IOI-HA items, the global score, and scores on the introspection and interaction subscales as dependent variables to examine whether the descriptive variables could predict these outcome measures. Scores on single IOI-HA items, the global score, and scores on the introspection (items 1, 2, 4, and 7) and interaction (items 3, 5, and 6) subscales closely resemble those previously reported. Multiple regression analysis showed that the best ear SDS predicts about 18-19% of the outcome on items 3 and 5 separately, and about 16% on the interaction subscale (sum of items 3, 5, and 6) CONCLUSIONS: The best ears SDS explains some of the variance displayed in the IOI-HA global score and the interaction subscale. The relation between SDS and IOI-HA suggests that a poor unaided SDS might in itself be a limiting factor for the HA rehabilitation efficacy and hence the IOI-HA outcome. The clinician could use this information to align the user's HA expectations to what is within possible reach. American Academy of Audiology.

We examined the different personality dimensions between depression and anxiety with Cloninger's seven-factor model of temperament and character. The Temperament and Character Inventory (TCI), which measures four temperament and three character dimensions of Cloninger's personality theory (125-item short version), the Self-rating Depression Scale (SDS), and the State-Trait Anxiety Inventory (STAI) were administered to 223 Japanese students. With hierarchical regression analysis, the SDS score was predicted by scores of Harm-Avoidance, Self-Directedness, and Self-Transcendence, even after controlling for the STAI score. The STAI score was predicted by scores of Self-Directedness and Cooperativeness, even after controlling for the SDS score. More importance should be attached to these dimensions of character because they might contribute to both depression and anxiety.

Duchenne and Becker muscular dystrophy (DMD/BMD) are caused by mutations in the dystrophin gene and are characterized by severe and mild progressive muscle wasting, respectively. Short stature has been reported as a feature of DMD in the Western hemisphere, but not yet confirmed in Orientals. Height of young BMD has not been fully characterized. Here, height of ambulant and steroid naive Japanese 179 DMD and 42 BMD patients between 4 and 10 years of age was retrospectively examined using height standard deviation score (SDS). The mean height SDS of DMD was -1.08 SD that was significantly smaller than normal (p < 0.001), indicating short stature of Japanese DMD. Furthermore, the mean height SDS of BMD was -0.27 SD, suggesting shorter stature than normal. Remarkably, the mean height SDS of DMD was significantly smaller than that of BMD (p < 0.0001). In DMD higher incidence of short stature (height SDS < -2.5 SD) was observed in Dp71 subgroup having mutations in dystrophin exons 63-79 than others having mutations in exons 1-62 (27.8% vs. 7.5%, p = 0.017). These suggested that height is influenced by dystrophin in not only DMD but also BMD and that dystrophin Dp71 has a role in height regulation. Copyright © 2017 Elsevier B.V. All rights reserved.

The effect of economic status (ES) on growth, insulin-like growth factor (IGF)-I and IGF-binding protein (IGFBP)-3 in healthy children is not well characterized. We aimed to study the interrelationship between height, weight, IGF-I, IGFBP-3, mid-parental height (MPH) and ES. Eight hundred and fourteen healthy children (428 boys, 386 girls; age 3-18 years) were classified according to income of the families as low, middle and high. Standard deviation scores (SDSs) of height, weight, MPH, IGF-I and IGFBP-3 were compared between the groups. The combined effect of these parameters and ES on height SDS was investigated with complex statistical models. There was a significant trend for height and weight SDSs to increase with higher income levels in boys, but not in girls. Body mass index (BMI) SDSs were similar in three groups. There was a general trend for MPH SDS to increase with income levels in both sexes. In boys, IGF-I SDS was significantly higher in high ES group than low ES. In girls, IGFBP-3 SDSs were significantly higher in high ES group than in middle ES group. For both genders, height SDS was highly correlated with weight SDS and moderately correlated with BMI SDS, MPH SDS and IGF-1 SDS. All correlations were significant and positive. Complex models showed that MPH (19%), IGF-I (13%) and ES (3%) in boys, and MPH (16%) and IGF-I (7%) in girls have significant contribution to height SDSs. ES per se, independent of overt malnutrition, affects height, weight, IGF-I and IGFBP-3 with some gender differences in healthy children. Influence of income on height and weight show sexual dimorphism, a slight but significant effect is observed only in boys. MPH is the most prominent variable effecting height in healthy children. Higher height and MPH SDSs observed in higher income groups suggest that secular trend in growth still exists, at least in boys, in a country of favorable economic development.

Objective Karoshi, which is the Japanese term for death from over-work, is usually the extreme result of cardiovascular diseases, and occupational stress plays a pivotal role in the pathogenesis. Depression is closely associated with atherosclerotic cardiovascular disease. The present study was undertaken to examine the relationship between occupational stress and depression. Methods We enrolled 231 consecutive outpatients with lifestyle-related diseases such as diabetes, hyperlipidemia and hypertension were enrolled. Occupational stress was measured by qualitative constructs assessing job control, job demands, and worksite social support using a job content questionnaire (JCQ). The job strain index measured by the ratio of job demands to job control was used as an indicator of the occupational stress. Depression was evaluated by the Self-rating Depression Scale (SDS). Results A univariate linear regression analysis showed the SDS scores to be positively correlated with job demands and the job strain index and negatively correlated with job control and worksite social support. Multiple regression analyses to predict the SDS scores demonstrated that job demands were positively associated with SDS scores and job control and worksite social support were negatively associated with SDS scores after controlling for other variables. The job strain index was positively related to SDS scores. Conclusion Occupational stress expressed as the job strain index was strongly associated with depression. By simultaneously using the SDS and JCQ, the health conditions of patients could be classified based on occupational stress and mental stress, and this classification could help to promote a healthy work environment and guide individual workers.

Prader-Willi syndrome (PWS) is a genetic disorder historically characterized by two phenotypic stages. The early phenotype in infants is associated with hypotonia, poor suck, and failure to thrive. In later childhood, PWS is associated with intellectual disability, hyperphagia, as well as growth and sex hormone deficiency. Little is known about the transition between phenotypes. This study investigates the nature of the change in infancy and childhood PWS. Forty-six children (22 females, 24 males; mean age 2 y 9 mo, SD 18.9 mo; range 7 mo-5 y) with genetically confirmed PWS participated. Information was obtained on childhood height and weight, and eating behaviour from case notes and by parental interview. Weight standard deviation scores (SDS) started to exceed height by the end of the first year. Height SDS appeared to fall from near normal at birth until stabilizing below normal around 2 years. Half of the children whose body mass index (BMI) was higher than normal at interview had food interests greater than that of their peers, and the age at which increased age-appropriate eating was first noted was later than the increase of BMI SDS. Obesity may develop before the increased interest in food, suggesting underlying physiological factors independent of appetite control may be important.

To report 12-month outcomes from a multidisciplinary child obesity intervention program, targeting high-risk groups. In this unblinded randomized controlled trial, participants (recruited January 2012-August 2014) were aged 5 to 16 years, resided in Taranaki, Aotearoa/New Zealand, and had BMI ≥ 98th percentile or BMI > 91st percentile with weight-related comorbidities. Randomization was by minimization (age and ethnicity), with participants assigned to an intense intervention group (home-based assessments at 6-month intervals and a 12-month multidisciplinary program with weekly group sessions) or to a minimal-intensity control group with home-based assessments and advice at each 6-month follow-up. The primary outcome was the change in BMI standard deviation score (SDS) at 12 months from baseline. A mixed model analysis was undertaken, incorporating all 6- and 12-month data. Two hundred and three children were randomly assigned (47% Māori, 43% New Zealand European, 53% female, 28% from the most deprived quintile, mean age 10.7 years, mean BMI SDS 3.12). Both groups displayed a change in BMI SDS at 12 months from baseline (-0.12 control, -0.10 intervention), improvements in cardiovascular fitness (P < 0.0001), and improvements in quality of life (P < 0.001). Achieving ≥ 70% attendance in the intense intervention group resulted in a change in BMI SDS of -0.22. This program achieved a high recruitment of target groups and a high rate of BMI SDS reduction, irrespective of intervention intensity. If retention is optimized, the intensive program doubles its effect. © 2017 The Obesity Society.

Evidence of the effects of fat mass and obesity-associated (FTO) gene variation and long-term effects of physical activity (PA) on adiposity in adolescents is largely scarce. This study aimed to investigate whether physical activity modulates the effects of the FTO gene on body mass index (BMI) changes in Japanese adolescents between the ages of 13 and 18 years. Data of 343 subjects (156 boys; 187 girls) who were enrolled in 2006 and 2007 from schools on Shunan City, Japan, were collected. Genotyping (rs1558902) was conducted, and anthropometric measurements and blood test results were recorded for subjects in the eighth grade. A second survey involving self-reporting of anthropometric measurements was conducted when the subjects were in the twelfth grade. PA was estimated using the International Physical Activity Questionnaire in this survey. BMI and the standard deviation score for BMI (BMI-SDS) were calculated. BMI changes and BMI-SDS changes were compared among FTO genotypes using a multivariate model. The effect of the interaction between PA and the FTO genotype on BMI changes was significant among boys but not girls. Among boys, PA had a significant negative influence on BMI-SDS changes in those with the AA genotype and a significant positive influence on BMI and BMI-SDS changes in those with the TT genotype. These data suggest that the influence of PA on BMI changes and BMI-SDS changes varied on the basis of genotype. PA modified the effect of the FTO gene on BMI changes in Japanese boys.

Children and adolescents suffering from inflammatory bowel disease (IBD) are at risk of developing osteoporosis as a result of treatment with corticosteroids as well as of nonsteroidal factors like inflammation and malnutrition. To study the impact of these factors on development of osteopathy, we compared the rate of osteoporosis in steroid-naive and steroid-treated pediatric IBD patients. In 90 patients (50 girls) with IBD (34 steroid-naive, 53 steroid-treated, 3 not known) aged 8.8 to 19.2 (14.4 +/- 2.2) years and 52 controls (27 girls) aged 6.1 to 17.6 (12.9 +/- 3.0) years, bone mineral density (BMD) of the lumbar spine was assessed with dual energy x-ray absorptiometry. Areal BMD values were transformed into volumetric densities called bone mineral apparent density (BMAD) and expressed as standard deviation scores (SDS) on the basis of the BMAD values of the controls. The rate of osteoporotic patients (BMAD-SDS < -2) was 8% in girls and 20% in boys. There was a similar proportion of osteoporosis in steroid-naive (12%) and steroid-treated (11%) patients. SDS of body height showed a significant positive correlation with BMD-SDS but not with BMAD-SDS in almost all patient subgroups, indicating an interfering dependency of BMD from bone size. The prevalence of osteoporosis in pediatric patients with IBD is approximately the same as in adult patients. Osteoporosis is already present before steroid treatment. Data of dual energy x-ray absorptiometry measurements should be transformed into volumetric parameters to compensate for short stature. Otherwise, a lot of growth-stunted patients may be falsely diagnosed as osteopenic.

The quality of life is compromised in children and adolescents with overweight or obesity. The aim of this study was to evaluate whether the quality of life improves during a community-based overweight and obesity treatment, and whether improvements depend on reductions in the degree of obesity. Quality of life was assessed using the Pediatric Quality of Life Inventory (PedsQL) 4.0 in children and adolescents aged 3-18 years with overweight or obesity [body mass index (BMI) ≥85th percentile] upon entry into a community-based chronic care overweight and obesity treatment based upon The Children's Obesity Clinic's Treatment protocol, and upon follow-up after 10-30 months of treatment. Height and weight were measured at each consultation and converted into a BMI standard deviation score (SDS). Upon entry, 477 children (212 boys) completed a PedsQL, and 317 (143 boys) completed another PedsQL after a median of 13 months of treatment. Quality of life improved (p < 0.001), regardless of sex, age, and pubertal development stage upon entry (p ≥ 0.108). Greater reductions in BMI SDS and high socioeconomic status were associated with greater improvements in the quality of life (p ≤ 0.047). However, improvements also occurred in children and adolescents with low socioeconomic status or who increased their BMI SDS (p < 0.001). Improvements in quality of life occurred in children and adolescents during a community-based overweight and obesity treatment, even in children and adolescents who increased their BMI SDS. Thus, improvements may be due to the treatment itself and not exclusively to reductions in BMI SDS. Clinicaltrials.gov, ID-no.: NCT02013843.

Previous studies reported a wide range of estimated malnutrition prevalence (6-30%) in paediatric inpatients based on various anthropometric criteria. We performed anthropometry in hospitalised children and assessed the relationship between malnutrition and length of hospital stay (LOS) and complication rates. In a prospective multi-centre European study, 2567 patients aged 1 month to 18 years were assessed in 14 centres in 12 countries by standardised anthropometry within the first 24 h after admission. Body mass index (BMI) and height/length <-2 standard deviation scores (SDS, WHO reference) were related to LOS (primary outcome), frequency of gastrointestinal (diarrhoea and vomiting) and infectious complications (antibiotic use), weight change during stay (secondary outcomes) and quality of life. A BMI <-2 SDS was present in 7.0% of the patients at hospital admission (range 4.0-9.3% across countries) with a higher prevalence in infants (10.8%) and toddlers aged 1-2 years (8.3%). A BMI <-2 to ≥-3 SDS (moderate malnutrition) and a BMI <-3 SDS (severe malnutrition) was associated with a 1.3 (CI95: 1.01, 1.55) and 1.6 (CI95: 1.27, 2.10) days longer LOS, respectively (p = 0.04 and p < 0.001). Reduced BMI <-2 SDS was also associated to lower quality of life, and more frequent occurrence of diarrhoea (22% vs 12%, p < 0.001) and vomiting (26% vs 14%, p < 0.001). Disease associated malnutrition in hospitalised children in Europe is common and is associated with significantly prolonged LOS and increased complications, with possible major cost implications, and reduced quality of life.

Early diagnosis of acromegaly prevents irreversible comorbidities and facilitates surgical cure. Carpal tunnel syndrome (CTS) is common in acromegaly and patients have often undergone surgery for CTS prior to the diagnosis of acromegaly. We hypothesized that screening CTS-patients for acromegaly could facilitate active case-finding. We prospectively enrolled 196 patients [135 women, 56.9 (range 23-103) years] who presented with CTS for surgery. Patients were asked about 6 symptoms suggestive of acromegaly using a questionnaire calculating a symptom score (0-6 points), and insulin-like-growth factor 1 (IGF-1) was measured. If IGF-1 was increased, IGF-1 measurement was repeated, and random growth hormone (GH) and/or an oral glucose tolerance test (OGTT) with assessment of GH-suppression were performed. The mean symptom score was 1.7±1.3 points. Three patients reported the maximal symptom score of 6 points, but none of them had an increased IGF-1. There was no correlation between the symptom score and IGF-1-SDS (standard deviation score) (r=0.026; p=0.71). Four patients had an IGF-1>2 SDS. In 2 patients acromegaly was ruled out using random GH and OGTT. One patient had normal IGF-1 and random GH at follow-up. One patient refused further diagnostics. In this prospective cohort of patients with CTS, the observed frequency of acromegaly was at most 0.51% (95% CI 0.03 to 2.83%). In this prospective study, none of the 196 patients with CTS had proven acromegaly. Thus, we see no evidence to justify general screening of patients with CTS for acromegaly. © Georg Thieme Verlag KG Stuttgart · New York.

Objective The aim of this study was to clarify the clinical conditions related to the depressive mental states in Japanese patients with subacute myelo-optico-neuropathy (SMON), caused by clioquinol intoxication more than 40 years previously. Materials and methods The changes in the mental states with aging were investigated in 25 Japanese SMON patients (mean age: 77.2 years old, range: 53-90) using a Japanese version of the Zung Self-rating Depression Scale (J-SDS) questionnaires with supportive interviews by the clinical psychotherapist and medical checkup records. These mental and medical examinations were repeated more than twice within 2 to 11 years' interval. The J-SDS questionnaires were also examined in 25 age-matched non-SMON elderly people. Results The total J-SDS scores of most of the SMON patients decreased with age without significant changes in the mean Barthel index scores during this study period. The mean J-SDS scores at the first and latest studies were significantly higher than in the age-matched healthy elderly people. The total J-SDS scores of the latest study were significantly correlated with the degree of physical disability, such as the inverse total Barthel index scores, severity of SMON or gait disturbance, but not with the age. Conclusion The total J-SDS scores of most of the SMON patients tended to decrease with age. Repeating mental supportive interviews and medical examinations by experts helped to improve the depressive mental state and revealed close relationship between the mental state and the physical disabilities of the SMON patients.

The aim of this study was to evaluate the effect of combined therapy with growth hormone (GH) and luteinizing hormone-releasing hormone agonist (LHRHa) on the near-final height (NFH) of children with idiopathic short stature (ISS) and growth hormone deficiency (GHD) in early puberty. A retrospective analysis of 20 patients with ISS and 9 patients with GHD treated with combined therapy was undertaken. Twelve children with ISS and ten with GHD, treated with GH alone, served as controls. Patients were matched at baseline for chronological age, bone age, height standard deviation score (SDS), and pubertal development. Patients with ISS or GHD treated with combined therapy improved both their predicted adult height (PAH) at 2 years of therapy (ISS, p < 0.001; GHD, p = 0.03) and their NFH (ISS, p < 0.05; GHD, p = 0.05). Treatment with combined therapy did not generate additional benefits on the PAH after 2 years of therapy (ISS children, an increase of 7.9 +/- 4.9 cm with combined therapy vs. 7.3 +/- 6.0 cm with GH; GHD children, an increase of 6.8 +/- 7.8 cm with combined therapy vs. 5 +/- 5.9 cm with GH). The total height gain SDS was higher in patients treated with GH alone compared with those with combined therapy, but the difference was not significant (ISS children, a gain of 2.4 SDS with GH vs. 0.8 SDS with combined therapy; GHD children, a gain of 1.8 SDS with GH vs. 0.6 SDS with combined therapy). Although 2 years of combined treatment with GH and LHRHa improved the PAH and the NFH of ISS and GHD patients in early puberty, this improvement was not significant compared with that observed in similar subjects treated with GH alone.

Emotional disturbance including depression is associated with increased mortality among dialysis patients. The Self-Rating Depression Scale (SDS) is a simple tool for assessing emotional disturbance. This study investigated the relationship between emotional conditions as assessed with the SDS test and mortality among 491 hemodialysis patients. At baseline, 183 (37.3%), 180 (36.7%), 108 (22.0%), and 20 (4.1%) were classified as normal, borderline depression, depression, and severe depression, respectively. During the two years of observation period, 57 of 491 (11.6%) died. The SDS scores in the non-survivors were significantly higher than those in the survivors (p<0.0001). Logistic analyses showed that the diagnoses made by the SDS test were associated with significantly greater risks for all-cause mortality (99%CI: 1.905-3.698 for that without adjustment, 1.999-4.382 for that with full adjustment). When the SDS score = 50 was selected as the cut off value, the test screened two-year all cause death with sensitivity = 57.9% and the specificity = 78.1%. In conclusion, hemodialysis patients had high prevalence of emotional disturbance assessed by the SDS test, and high SDS score was significantly associated with all-cause mortality. These findings underscore the importance of screening for emotional conditions using the SDS test among hemodialysis patients.

Somapacitan is a reversible albumin-binding growth hormone (GH) derivative, developed for once-weekly administration. This study aimed to evaluate the safety of once-weekly somapacitan vs once-daily Norditropin ® . Local tolerability and treatment satisfaction were also assessed. 26-week randomized, controlled phase 3 safety and tolerability trial in six countries (Nbib2382939). Male or female patients aged 18-79 years with adult GH deficiency (AGHD), treated with once-daily GH for ≥6 months, were randomized to once-weekly somapacitan ( n  = 61) or once-daily Norditropin ( n  = 31) administered subcutaneously by pen. Both treatments were dose titrated for 8 weeks to achieve insulin-like growth factor I (IGF-I) standard deviation score (SDS) levels within the normal range, and then administered at a fixed dose. Outcome measures were adverse events (AEs), including injection site reactions; occurrence of anti-somapacitan/anti-GH antibodies and change in treatment satisfaction, assessed using the Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9). Mean IGF-I SDS remained between 0 and 2 SDS throughout the trial in both groups. AEs were mostly mild or moderate and transient in nature. The most common AEs were nasopharyngitis, headache and fatigue in both groups. More than 1500 somapacitan injections were administered and no clinically significant injection site reactions were reported. No anti-somapacitan or anti-GH antibodies were detected. The TSQM-9 score for convenience increased significantly more with somapacitan vs Norditropin ( P  = 0.0171). In this 26-week trial in patients with AGHD, somapacitan was well tolerated and no safety issues were identified. Once-weekly somapacitan was reported to be more convenient than once-daily Norditropin. © 2018 The authors.

Vernal keratoconjunctivitis (VKC) is a chronic conjunctivitis that mainly affects children living in temperate areas. The notable difference between genders and VKC's resolution with puberty have persistently suggested a role of hormonal factors in VKC development. To describe six cases of males with VKC and growth hormone deficiency (GHD) reported as a long-term follow-up during rhGH treatment. Six consecutive male patients (median age at GHD diagnosis 9.7, range 7.9 to 13.1 years) with VKC, were recruited from July 2005 to July 2013 at the Paediatric Endocrinology Unit of Anna Meyer Children's Hospital in Florence, Italy. In these patients, anthropometric data were collected periodically. In three of these patients, data were collected to near-adult or adult height. Familial history was uneventful for all patients. The target height was normal, ranging from 0.65 standard deviation scores (SDS) to 2.01 SDS. The patients showed a normal birth-weight (from -1.21 to 1.35 SDS) and birth-length (from -0.93 to 1.21 SDS). At GHD diagnosis, all of the patients exhibited demonstrated important growth retardation (from -2.05 to -2.78 SDS). Plasmatic concentrations of IGF-1 and IGFBP-3 were low (from -1.85 to -3 SDS and from -1.81 to -2.76 SDS, respectively). GH stimulation tests showed classic GHD symptoms in all of the patients. Pubertal onset was normal. All of the patients treated with rhGH responded well to rhGH treatment. Adult height, evaluated in three patients, was in accordance with their target height. To our current knowledge, we have described for the first time six patients affected by VKC with GH deficiency, in some of whom we performed a long-term follow-up to adult height. Further studies will be needed to establish whether GHD may be a common feature of VKC patients. Nevertheless, it appears to be useful to carefully follow statural growth of VKC patients, while the possibility of a GH deficiency must to be taken into account in the presence of growth failure.

Background Due to the pandemic of child and adolescent overweight and obesity, improvements in overweight and obesity treatment availability and accessibility are needed. Methods In this prospective study, we investigated if reductions in body mass index (BMI) standard deviation scores (SDS) and waist circumference (WC) would occur during 1.5 years of community-based overweight and obesity treatment based upon an effective hospital-based overweight and obesity treatment protocol, The Children’s Obesity Clinics’ Treatment protocol. Height, weight, and WC were measured at all consultations. Changes in BMI SDS and WC were analyzed using linear mixed models based upon the repeated measures in each child. Results From June 2012 to January 2015, 1,001 children (455 boys) were consecutively enrolled in the community-based treatment program. Upon entry, the median age was 11 years (range: 3−18), and the median BMI SDS was 2.85 (range: 1.26−8.96) in boys and 2.48 (range: 1.08−4.41) in girls. After 1.5 years of treatment BMI SDS was reduced in 74% of the children. BMI SDS was reduced by a mean of 0.38 (95% confidence interval (CI): 0.30−0.45, p<0.0001) in boys and 0.18 (95% CI: 0.12−0.25, p<0.0001) in girls after 1.5 years of treatment, independently of baseline age, BMI SDS, and Tanner stage (all p>0.08). WC was reduced by a mean of 3.8 cm (95% CI: 2.7−4.9, p>0.0001) in boys and 5.1 cm (95% CI: 4.0−6.2, p>0.0001) in girls. The dropout rate was 31% after 1.5 years. A median of 4.5 consultation hours was invested per child per year. Conclusion BMI SDS and WC were reduced after 1.5 years of treatment. Hence, this community-based overweight and obesity treatment program may help accommodate the need for improvements in treatment availability and accessibility. PMID:28264043

Growth hormone (GH) registries indicate that boys receive preferential GH treatment for idiopathic short stature (ISS). The aim was to determine whether age, auxological parameters, pubertal status, and target height differ between genders at GH initiation. Review of the computerized files of the endocrine department of a tertiary pediatric medical center identified 184 patients who started GH therapy for ISS between 2003-2011. Data on auxologic parameters, predicted height, parental height, and pubertal status were collected and compared between boys and girls. Boys accounted for a significantly higher percentage of the study group (65.8%, p<0.001). At onset of GH therapy, there were no significant differences between boys and girls in age (10.2±3.1 vs. 9.9±2.4 years), height-standard deviation score (SDS) (-2.64±0.5 vs. -2.79±0.5), body mass index-SDS[(-0.65±1.01) vs. (-0.80±1.13)], or pubertal status (66% vs. 63.5% prepubertal). Predicted height-SDS was significantly higher in boys (-1.95±1.05 vs. -2.56±0.73, p<0.001). Midparental height-SDS was similar in the two groups, as were paternal and maternal height. The similar age, height deficit, and pubertal status at onset of GH treatment in boys and girls suggests that gender differences do not exist. Male predominance may stem from family preferences to treat boys. Future studies are warranted to assess the psychosocial aspects in the decision to initiate therapy.

The aim of this study was to compare ambulatory blood pressure monitoring (ABPM) parameters in offspring with at least one hypertensive parent (HP) to offspring with normotensive parents (NP) and to determine whether gender of parent or child might influence the association between parental hypertension and blood pressure (BP). Eighty-nine healthy children (mean age 11.1 +/- 3.9 years) with HP and 90 controls (mean age 10.5 +/- 3.1 years) with NP were recruited. Age, gender, and height did not differ between the two groups, whereas children of HP had higher weight, body mass index (BMI), and waist circumference compared with healthy controls. No difference was found in casual BP between the two groups. In contrast, during ABPM daytime and nighttime mean systolic and diastolic BP and mean arterial pressure (MAP) standard deviation scores (SDS) were significantly elevated in children with HP. The mean percentage of nocturnal BP decline (dipping) was not significantly different between the two groups. Children with hypertensive mothers had higher daytime systolic and MAP SDS than controls; no such difference was detected for children with hypertensive fathers. Daytime systolic and MAP SDS were significantly elevated in boys with HP compared with boys with NP but failed to be significant in girls. Multiple linear regression analysis showed that parental history of hypertension (B = 0.29) and BMI (B = 0.03) were independently correlated with increase of daytime MAP SDS. Early changes in ambulatory BP parameters were present in healthy children of HP. BP in HP offspring was influenced by the gender of the affected parent and the offspring.

Obese children and adolescents often exhibit progressively declining motor skills. To support young obese patients adequately, it is necessary to assess their individual physical and motor abilities, taking the degree of obesity into account. A total of 5 924 children and adolescents (mean age: 12.7±2.5 years, range 6.0-18.0 years, 3 195 girls) were examined in a standardised multicentre evaluation survey (APV). Fitness parameters were correlated with age- and gender-specific BMI-SDS (Standard Deviation Score) Methods: Anthropometric data were collected and patients performed the modified Munich fitness test (mMFT: maximal power, coordination, trunk flexibility) and a 6-min walk-test (aerobic endurance capacity). 33% of patients were extremely obese (BMI>99.5th percentile). Mean BMI-SDS was + 2.32±0.53 (♀-Δ=+ 0.06; p<0.001). The data indicated significant negative correlations between BMI-SDS and selected components of motor performance, especially maximal power (r=- 0,134), and particularly aerobic endurance capacity (r=- 0,214; all p<0.001). Motor performance was significantly below average (n=27 473, 6-18 years), especially among extremely obese patients. Performance in all motor tasks was lower in girls compared to boys, except for trunk flexibility (p<0.001). Correlations were found between BMI-SDS and motor performance. Extremely obese patients and obese girls showed the most pronounced motor deficits. These results emphasize the importance of standardized evaluation of individual motor performance in children and adolescents with obesity. © Georg Thieme Verlag KG Stuttgart · New York.

Obesity is associated with normal or increased growth despite diminished GH secretion compared to lean children. The mechanism by which adequate growth is maintained in the presence of low GH levels is unknown, but is possibly mediated at the GH receptor level. To probe this hypothesis, we examined the relationship between GH responsivity, body mass index (BMI) and plasma GH-binding protein (GH-BP)/receptor level in 43 GH-deficient children during treatment with a fixed dose of GH (0.18 mg/kg.week). Before treatment, BMI [expressed as standard deviation score (SDS) for age (BMI-SDS)] did not correlate with either growth velocity or serum insulin-like growth factor-I (IGF-I). In contrast, after 12 months of GH therapy BMI-SDS correlated directly with plasma IGF-I (P < 10(-5)) and growth velocity (P < 10(-3)). These findings parallel those obtained for GH-BP vs. the response to GH, suggesting that BMI and GH-BP are covariants. The interrelationships among BMI, GH-BP, and response to GH were further probed by multiple regression analysis. Partial correlation coefficients vs. response to GH were consistently stronger for GH-BP than for BMI-SDS, indicating that GH-BP is the dominant factor between these two covariants in determining responsiveness to GH. The data suggest a primary role for GH-BP/receptor levels in determining GH action, with secondary but significant effects of nutrition and degree of adiposity. The latter may be mediated through the impact of nutrition and body mass on GH-BP/receptor levels.

To study the effect of the insulin-like growth factor (IGF) system on growth, adiposity and systolic blood pressure (SBP) in early life in British-born South Asian (SA) and White European (WE) children. The effect of IGF-1 and insulin-like growth factor-binding protein 3 (IGFBP-3) over the first 4 years in 204 healthy SA and WE children was investigated by mixed linear regression modelling. This enabled inclusion of all follow-up observations and adjustment for repeated measures. At birth, SA babies were shorter and lighter than WE babies. Over 4 years, SA ethnicity was associated with lower height, weight and body mass index (BMI) standard deviation score (SDS), higher subscapular/triceps skinfold thickness (Ss/Tr SFT) and lower SBP (all p < 0.01). IGF-1 was associated with greater height (p = 0.03), weight (p < 0.001) and BMI SDS (p < 0.001), and IGFBP-3 with greater weight SDS (p < 0.001), BMI SDS (p = 0.001), Ss/Tr SFT (p = 0.003) and SBP (p = 0.023). Over this first 4-year period of life, SA ethnicity was associated with being shorter, lighter, having more superficial truncal adiposity and lower SBP. IGFBP-3 (and not IGF-1) was independently associated with both superficial truncal adiposity and SBP, suggesting that IGFBP-3 is a potential metabolic and cardiovascular marker in healthy children in the early years of life.

Idiopathic short stature (ISS) is short stature of unknown cause. In 2003, the Food and Drug Administration (FDA) approved the use of growth hormone (GH) for ISS. Several studies have evaluated the effect of GH in children with ISS, in whom improved growth velocities and height standard deviation scores (SDS) have been reported. However, clinical variables influence the height improvement. This study aimed to evaluate the effects of GH treatment on ISS and to analyze clinical factors associated with growth velocity. This study was conducted retrospectively. Subjects diagnosed with ISS at Ajou University Hospital were divided into two groups, an ISS with GH-treatment group (n=34) and an ISS control group (n=36). All children were prepubertal, and aged <10 years. We reviewed their auxological data, laboratory findings, and bone age. Growth velocity of the GH-treatment group exceeded that of controls by 3.37 cm/year (95% CI, 2.78-3.95). At baseline, the mean SDS for height in the treatment and control groups were equivalent (-2.25 ± 0.29 and -2.22 ± 0.31, respectively). However, after 1 year, the height of the GH-treated group exceeded that of the control group by 0.73 SDS (95% CI, 0.57-0.88). A negative correlation was found between age and growth velocity in the GH-treatment group. GH treatment increased short-term growth velocity and height SDS of Korean children with ISS. Age was identified as the single most important factor correlated with growth velocity in GH treatment.

Cornelia de Lange syndrome (CdLS) is a both clinically and genetically heterogeneous syndrome. In its classical form, it is characterised by distinctive facial features, intra-uterine growth retardation, short stature, developmental delay, and anomalies in multiple organ systems. NIPBL, SMC1A, SMC3, RAD21 and HDAC8, all involved in the cohesin pathway, have been identified to cause CdLS. Growth hormone (GH) secretion has been reported as normal, and to our knowledge, there are no reports on the effect of recombinant human GH treatment in CdLS patients. We present a patient born small for gestational age with persistent severe growth retardation [height -3.4 standard deviation score (SDS)] and mild dysmorphic features, who was treated with GH from 4.3 years of age onward and was diagnosed 6 years later with CdLS using whole-exome sequencing. Treatment led to a height gain of 1.6 SDS over 8 years. Treatment was interrupted shortly due to high serum insulin-like growth factor-1 serum values. In conclusion, GH therapy may be effective and safe for short children with CdLS.

The long-lasting impact of different neglectful environments on growth in children is not well studied. Three groups of children, 3-10 years old, were recruited (n=60): previously institutionalized international adoptees living in stable home environments for at least 2 years (IA; n=15), children with a history of neglect born in the USA (USN; n=17), and controls (n=28). Children underwent physical examination, anthropometry, and collection of serum for growth parameters. Mean height standard deviation scores (SDS) were different (p<0.05). Age-adjusted head circumference (HC) was significantly smaller (p<0.05) in IAs. Insulin growth factor (IGF-1), a marker of growth hormone action, was higher in US neglected children. IGF-1 adjusted for age and weight SDS were different (p<0.05) between control and US neglect groups. The degree of growth failure in height and HC in IAs was more severe than neglected US children. These findings may reflect differences between the impact of chronic and intermittent deprivation on the growth hormone system.

What treatment for a child with tall stature?

PubMed

Edouard, Thomas

2017-06-01

Tall stature is statistically defined as a height standard deviation score (SDS) above 2 for a given age, sex and population group. The most common cause of tall stature is constitutional (often familial) tall stature. However, underlying endocrine or genetic disorders must be considered as some of them may require specific treatment or management. In constitutional tall stature, healthy children are referred to discuss treatment aiming at reducing adult height. The indications of treatment are rare and usually discussed in girls with extremely tall stature (height SDS>4, corresponding to 185cm in girls). The treatment options for tall children are limited and concerns have been raised about their long-term safety. Indeed, recent studies have suggested that high-dose estrogens in adolescent girls may be associated with an increased risk of infertility, as well as increased risk of cancer. Surgical epiphysiodesis has also been reported to reduce adult height but this invasive procedure in healthy children can be questionable and further data on its safety profile are required.

3-M syndrome is a rare autosomal recessive disorder that causes short stature, unusual facial features and skeletal abnormalities. Mutations in the CUL7, OBSL1 and CCDC8 genes could be responsible for 3-M syndrome.Here we describe the growth and evolution of dismorphic features of an Italian boy with 3-M syndrome and growth hormone deficiency (GHD) from birth until adulthood. He was born full term with a very low birth weight (2400 g=-3.36 standard deviation score, SDS) and length (40.0 cm =-6.53 SDS). At birth he presented with a broad, fleshy nose with anteverted nostrils, thick and patulous lips, a square chin, curvilinear shaped eyebrows without synophrys, short thorax and long slender bones. Then, during childhood tall vertebral bodies, hip dislocation, transverse chest groove, winged scapulae and hyperextensible joints became more evident and the diagnosis of 3-M syndrome was made; this was also confirmed by the finding of a homozygous deletion in exon 18 of the CUL7 gene, which has not been previously described.The patient also exhibited severe GHD (GH <5 ng/ml) and from the age of 18 months was treated with rhGH. Notwithstanding the early start of therapy and good compliance, his growth rate was always very low, except for the first two years of treatment and he achieved a final height of 132 cm (-6.42 SDS).

Studies of the effect of oxcarbazepine (OXC) on body growth of children with epilepsy are rare and their results are controversial. To the contrary, many studies have shown significant weight gain following valproate (VPA) treatment. To prospectively evaluate the effect of OXC monotherapy on growth patterns of children with epilepsy and compare it with the effect of VPA monotherapy. Fifty-nine otherwise healthy children, aged 3.7-15.9 years, with primary generalized, partial or partial with secondary generalization seizure disorder, were included in the study. Twenty six children were placed on OXC and thirty three on VPA monotherapy. Body weight (BW), height and body mass index (BMI) as well as their standard deviation scores (SDS), were evaluated prior to as well as 8 months post initiation of OXC or VPA therapy. Eight months post OXC-treatment, BW, SDS-BW, BMI and SDS-BMI increased significantly. The increase was similar to that observed in the VPA group. An additional 15.4% of children in the OXC group and 21.2% in the VPA group became overweight or obese. The effect of both OXC and VPA therapy on linear growth did not reach statistical significance. Similarly to VPA, OXC monotherapy resulted in a significant weight gain in children with epilepsy. Careful monitoring for excess weight gain along with counseling on adapting a healthy lifestyle should be offered to children on OXC therapy. Copyright © 2016 Elsevier B.V. All rights reserved.

Adolescents with obesity have increased risk of type 2 diabetes and metabolic syndrome (MetS). Pancreatic fat has been related to these conditions; however, little is known about associations in pediatric obesity. The present study was designed to explore these associations further. We examined 116 subjects, 90 with obesity. Anthropometry, MetS, blood samples, and oral glucose tolerance tests were assessed using standard techniques. Pancreatic fat fraction (PFF) and other fat depots were quantified using magnetic resonance imaging. The PFF was elevated in subjects with obesity. No association between PFF and body mass index-standard deviation score (BMI-SDS) was found in the obesity subcohort. Pancreatic fat fraction correlated to Insulin Secretion Sensitivity Index-2 and Homeostatic Model Assessment of Insulin Resistance in simple regression; however, when using adjusted regression and correcting for BMI-SDS and other fat compartments, PFF correlated only to visceral adipose tissue and fasting glucose. Highest levels of PFF were found in subjects with obesity and MetS. In adolescents with obesity, PFF is elevated and associated to MetS, fasting glucose, and visceral adipose tissue but not to beta-cell function, glucose tolerance, or BMI-SDS. This study demonstrates that conclusions regarding PFF and its associations depend on the body mass features of the cohort.

Hypochondroplasia (HCH) is a skeletal dysplasia characterized by disproportionate short stature. The aims of the study are to evaluate efficacy and safety of recombinant human growth hormone (r-hGH) therapy in HCH children, when compared with a historical cohort of untreated HCH children. Nineteen HCH patients with an initial height standard deviation score (SDS) ≤-2 and a mean age of 9.3 ± 3.1 years were treated with a mean r-hGH dose of 0.053 mg/kg/day over 3 years. Growth charts were derived from the historical cohort (n = 40). Height gain in the treated population was +0.62 ± 0.81 SDS greater than in the general population, and +1.39 ± 0.9 SDS greater than in the historical untreated HCH cohort (mean gain of 7.4 ± 6.6 cm gain). A negative correlation between height gain and age at treatment initiation was reported (p = 0.04). There was no significant difference in response between patients with fibroblast growth factor receptor 3 mutations and those without. No treatment-related serious adverse events were reported. r-hGH treatment is well tolerated and effective in improving growth in HCH patients, particularly when started early. The treatment effect varies greatly and must be evaluated for each patient during treatment to determine the value of continued therapy. © 2014 S. Karger AG, Basel.

Objective: In this post hoc analysis, improvement in functional impairment in patients with major depressive disorder (MDD) treated with levomilnacipran extended release (ER) was evaluated by assessing shifts from more severe to less severe functional impairment categories on individual Sheehan Disability Scale (SDS) subscales. Method: SDS data were pooled from 5 phase II/III studies conducted between December 2006 and March 2012 of levomilnacipran ER versus placebo in adult patients with MDD (DSM-IV-TR criteria). Proportions of patients shifting from moderate-extreme baseline impairment (score ≥ 4) to mild-no impairment (score ≤ 3) at end of treatment were assessed for each SDS subscale. Proportions of patients shifting from marked-extreme (score ≥ 7) baseline impairment to moderate-no (score ≤ 6) or mild-no impairment (score ≤ 3) at end of treatment, and shifts in which patients worsened from moderate-no to marked-extreme impairment, were also evaluated. Results: A significantly higher proportion of patients treated with levomilnacipran ER than placebo-treated patients improved from more severe categories of functional impairment at baseline to less severe impairment categories across all SDS subscales: work/school, social life, and family life/home responsibilities (P < .01). Depending on the SDS subscale, 48%–55% of levomilnacipran ER–treated patients with moderate-extreme impairment at baseline improved to mild or no impairment, compared with no more than 40% of placebo patients on any subscale. Almost half (42%–47%) of levomilnacipran ER–treated patients versus only about one-third (29%–34%) of placebo patients improved from marked-extreme to mild or no impairment across functional domains. Conclusions: These results suggest that functional improvement was observed across the SDS functional domains. To our knowledge, this is the first such categorical analysis of functional improvement, as measured by the SDS, for an antidepressant.

The aim of this study was to determine the effects of physical activity on systemic blood pressure (BP) and early markers of atherosclerosis in pre-pubertal obese children. Hypertension and endothelial dysfunction are premature complications of obesity. We performed a 3-month randomized controlled trial with a modified crossover design: 44 pre-pubertal obese children (age 8.9 + or - 1.5 years) were randomly assigned (1:1) to an exercise (n = 22) or a control group (n = 22). We recruited 22 lean children (age 8.5 + or - 1.5 years) for baseline comparison. The exercise group trained 60 min 3 times/week during 3 months, whereas control subjects remained relatively inactive. Then, both groups trained twice/week during 3 months. We assessed changes at 3 and 6 months in office and 24-h BP, arterial intima-media thickness (IMT) and stiffness, endothelial function (flow-mediated dilation), body mass index (BMI), body fat, cardiorespiratory fitness (maximal oxygen consumption [VO(2)max]), physical activity, and biological markers. Obese children had higher BP, arterial stiffness, body weight, BMI, abdominal fat, insulin resistance indexes, and C-reactive protein levels, and lower flow-mediated dilation, VO(2)max, physical activity, and high-density lipoprotein cholesterol levels than lean subjects. At 3 months, we observed significant changes in 24-h systolic BP (exercise -6.9 + or - 13.5 mm Hg vs. control 3.8 + or - 7.9 mm Hg, -0.8 + or - 1.5 standard deviation score [SDS] vs. 0.4 + or - 0.8 SDS), diastolic BP (-0.5 + or - 1.0 SDS vs. 0 + or - 1.4 SDS), hypertension rate (-12% vs. -1%), office BP, BMI z-score, abdominal fat, and VO(2)max. At 6 months, change differences in arterial stiffness and IMT were significant. A regular physical activity program reduces BP, arterial stiffness, and abdominal fat; increases cardiorespiratory fitness; and delays arterial wall remodeling in pre-pubertal obese children.

To assess the distribution of autonomic nervous system (ANS) dysfunction in overweight and obese children. Parasympathetic and sympathetic ANS function was assessed in children and adolescents with no evidence of impaired glucose metabolism by analysis of heart rate variability (low frequency power ln(LF), high frequency power, ln(HF); ln(LF/HF) ratio, ratio of longest RR interval during expiration to shortest interval during inspiration (E/I ratio), root mean square of successive differences (RMSSD); sympathetic skin response (SSR); and quantitative pupillography (pupil diameter in darkness, light reflex amplitude, latency, constriction velocity, re-dilation velocity). The relationship of each ANS variable to the standard deviation score of body mass index (BMI-SDS) was assessed in a linear model considering age, gender and pubertal stage as co-variates and employing an F-statistic to compare the fit of nested models. Group comparisons between normal weight and obese children as well as an analysis of dependence on insulin resistance (as indexed by the Homeostasis Model Assessment of Insulin Resistance, HOMA-IR) were performed for parameters shown to correlate with BMI-SDS. Statistical significance was set at 5%. Measurements were performed in 149 individuals (mean age 12.0 y; 90 obese 45 boys; 59 normal weight, 34 boys). E/I ratio (p = 0.003), ln(HF) (p = 0.03), pupil diameter in darkness (p = 0.01) were negatively correlated with BMI-SDS, whereas ln(LF/HF) was positively correlated (p = 0.05). Early re-dilation velocity was in trend negatively correlated to BMI-SDS (p = 0.08). None of the parameters that depended significantly on BMI-SDS was found to be significantly correlated with HOMA-IR. These findings demonstrate extended ANS dysfunction in obese children and adolescents, affecting several organ systems. Both parasympathetic activity and sympathetic activity are reduced. The conspicuous pattern of ANS dysfunction raises the possibility that obesity may give rise to dysfunction of the peripheral autonomic nerves resembling that observed in normal-weight diabetic children and adolescents.

Maternal obesity may affect cardiovascular outcomes in the offspring. We examined the associations of maternal prepregnancy body mass index and gestational weight gain with childhood cardiac outcomes and explored whether these associations were explained by parental characteristics, infant characteristics or childhood body mass index. In a population-based prospective cohort study among 4852 parents and their children, we obtained maternal weight before pregnancy and in early, mid- and late pregnancy. At age 6 years, we measured aortic root diameter (cm) and left ventricular dimensions. We calculated left ventricular mass (g), left ventricular mass index (g m(-2.7)), relative wall thickness ((2 × left ventricular posterior wall thickness)/left ventricular diameter), fractional shorting (%), eccentric left ventricular hypertrophy and concentric remodeling. A one standard deviation score (SDS) higher maternal prepregnancy body mass index was associated with higher left ventricular mass (0.10 SDS (95% confidence interval (CI) 0.08, 0.13)), left ventricular mass index (0.06 SDS (95% CI 0.03, 0.09)) and aortic root diameter (0.09 SDS (95% CI 0.06, 0.12)), but not with relative wall thickness or fractional shortening. A one SDS higher maternal prepregnancy body mass index was associated with an increased risk of eccentric left ventricular hypertrophy (odds ratio 1.21 (95% CI 1.03, 1.41)), but not of concentric remodeling. When analyzing the effects of maternal weight in different periods simultaneously, only maternal prepregnancy weight and early pregnancy weight were associated with left ventricular mass, left ventricular mass index and aortic root diameter (P-values<0.05), independent of weight in other pregnancy periods. All observed associations were independent of parental and infant characteristics, but attenuated to non-significance after adjustment for childhood body mass index. Maternal prepregnancy body mass index and weight gain in early pregnancy are both associated with offspring cardiac structure in childhood, but these associations seem to be fully explained by childhood body mass index.

To investigate the effect of age at growth hormone (GH) treatment start on near adult height (NAH) in children with isolated GH deficiency (GHD). NordiNet® International Outcome Study (IOS) (Nbib960128), a non-interventional, multicentre study, evaluates the long-term effectiveness and safety of Norditropin® (somatropin) (Novo Nordisk A/S) in the real-life clinical setting. Patients ( n  = 172) treated to NAH (height at ≥18 years, or height velocity <2 cm/year at ≥16 (boys) or ≥15 (girls) years) were grouped by age (years) at treatment start (early (girls, <8; boys, <9), intermediate (girls, 8-10; boys, 9-11) or late (girls, >10; boys, >11)) and GHD severity (<3 ng/mL or 3 to ≤10 ng/mL). Multiple regression analysis was used to evaluate the effect of age at treatment start (as a categorical and continuous variable) on NAH standard deviation score (SDS). Age at treatment start had a marked effect on NAH SDS; NAH SDS achieved by patients starting treatment early ( n  = 40 (boys, 70.0%); least squares mean (standard error) -0.76 (0.14)) exceeded that achieved by those starting later (intermediate, n  = 42 (boys, 57.1%); -1.14 (0.15); late, n  = 90 (boys, 68.9%); -1.21 (0.10)). Multiple regression analysis showed a significant association between NAH SDS and age at treatment start ( P  < 0.0242), baseline height SDS (HSDS) ( P  < 0.0001), target HSDS ( P  < 0.0001), and GHD severity ( P  = 0.0012). Most (78.5%) patients achieved a normal NAH irrespective of age at treatment start. Early initiation of GH treatment in children with isolated GHD improves their chance of achieving their genetic height potential. © 2017 The authors.

Background Childhood growth affects long-term health and could contribute to health inequalities that persist throughout life. Methods We compared growth data of 4-6 year old children born 1997-2002 in UK (n=15,168), Sweden (n=6,749) and rural China (n=10,327). Standard deviation scores (SDS) were calculated against the WHO Standard. Obesity and overweight were defined by International Obesity Taskforce cut-offs, and stunting, underweight and thinness by height, weight or BMI < −2 SDS. Associations with maternal education were standardised by calculating the Slope Index of Inequality (SII). Results Mean SDS height, weight and BMI in UK (−0.01; 0.42; 0.62, respectively) and Sweden (0.45; 0.59; 0.45) were higher than in China (−0.98, −0.82, −0.29). Higher maternal education was consistently associated with taller offspring height SDS (SII: UK 0.25; Sweden 0.17; China 1.06). Underweight and stunting were less common in UK (prevalence: 0.6% and 2.2%, respectively) and Sweden (0.3% and 0.6%) than in China (9.5% and 16.4%), where these outcomes were inversely associated with maternal education (SII: −25.8% and −12.7%). Obesity prevalence in UK, Sweden and China was 4.8%, 3.7% and 0.4%, respectively. Maternal education was inversely associated with offspring obesity in UK (SII: −3.3%) and Sweden (−2.8%), but not in China (+0.3%). Conclusions Higher maternal education was associated with more favourable growth in young children: lower obesity and overweight in UK and Sweden, and lower stunting and underweight in rural China. Public health strategies to optimize growth in early childhood need to acknowledge socioeconomic factors, but possibly with a different emphasis in different settings. PMID:23450064

Levothyroxine (L-T4) treatment of euthyroid children with Hashimoto thyroiditis (HT) is a controversial issue. We conducted a prospective, randomized, controlled clinical trial. Out of 79 identified euthyroid patients, 59 started the study; 25 patients (21 female, 4 male; age: 11.8 ± 2.3 years) received L-T4 at a mean dose of 1.6 µg/kg (SD, 0.8) daily, and 34 (27 female, 7 male; age: 12.6 ± 1.2 years) were not treated. Patients developing subclinical hypothyroidism during follow-up (n = 13) were treated with L-T4 and removed from the observation group. As the main outcome measures, thyroid gland volume (determined by ultrasound) as well as serum levels of TSH, free T4, and antibodies against thyroid peroxidase and thyroglobulin were assessed every 6 months for 36 months. At the start, the mean thyroid volume (standard deviation score, SDS) was 2.5 in the treatment group and 1.6 in the observation group. There was a constant decline in mean thyroid volume (SDS) from 2.13 (month 12) to 1.12 (month 30) in the treated group, with a delta thyroid volume of -1.01 SDS. In the observation group, the mean delta thyroid volume increased to +0.27 SDS. The change of the delta thyroid volume was statistically significantly different between both groups during the 12- and 30-month time points (p < 0.05). L-T4 had no effect on thyroid function and serum thyroid antibodies. L-T4 treatment can decrease the thyroid volume in euthyroid children with HT, but the effect is limited to a definite time period. © 2015 S. Karger AG, Basel.

Parental height is the most important identifiable factor influencing final height (FH) of children with growth hormone (GH) deficiency (GHD), treated with GH. Assessment of FH of patients with GHD--classified into familial short stature (FSS) and non-familial short stature (non-FSS) according to parentally adjusted deficit of height. The analysis comprised 101 patients (76 boys) with childhood-onset GHD. Final height was compared with patients' height before GH therapy, predicted adult height (PAH) and target height (TH). Both GH peak in stimulating tests and height standard deviation score (SDS) before the therapy were significantly lower in non-FSS than in FSS. Target height was significantly lower in FSS than in non-FSS. Parentally-adjusted deficit of height was significantly more profound in non-FSS than in FSS. The prognosis of adult height was very similar in both groups of patients, being significantly worse in non-FSS than in FSS while corrected by TH. The absolute FH was similar in FSS and non-FSS, being, however, significantly lower in non-FSS than in FSS while corrected by TH. Improvement of height was significantly better in non-FSS than in FSS. In both groups, FH SDS was significantly better than height SDS before the therapy (H0SDS). In FSS group, PAH was similar to TH, moreover, FH corresponded to both PAH and TH. In non-FSS group FH was significantly higher than PAH, but both FH and PAH were significantly lower than TH. 1) Growth hormone therapy was more effective in the patients with non-FSS than in those with FSS. 2) Parentally-adjusted deficit of height is an important prognostic factor of GH therapy effectiveness.

Since populations are becoming increasingly multi-ethnic, the use of local or international charts is a matter of debate. This study aimed to evaluate how the choice of cut-off thresholds affected prevalence of underweight (UW), overweight (OW), obesity (OB) in 1200 11-12-year Italian adolescents, and how their somatic growth depended on parental origin. The height, weight and body mass index were expressed as standard deviation score (SDS) using Italian (ISPED-2006) and UK (UK-1990) charts. The classification of UW/OW/OB was computed with the IOTF international cut-offs, and thresholds were identified as centiles corresponding to BMI values of 18.5/25.0/30.0 kg/m 2 at 18-year in ISPED-2006 or UK-1990 references. About 30% participants had non-Italian parents, above all from North-Africa and Romania. Referring to the UK-1990 charts, all groups showed negative mean SDS for height, and positive SDS for weight and BMI. Referring to the ISPED-2006 charts, all mean SDS were negative. Percentage of UW individuals was higher in accordance with ISPED-2006 than with UK-1990 charts, whereas percentages of OW/OB were higher with UK-1990 than ISPED-2006 charts. The results obtained using IOFT cut-offs were similar to UK-1990 cut-offs. These results were due to the different shape of age-dependent cut-off centiles. Independently by the parental origin, the percentages of adolescents classified as OW/OB were closer to the expected values using the ISPED-2006 then the UK-1990 cut-offs. The results suggested the use of the Italian references for adolescents with immigrant parents. The use of local charts seems more appropriate at least in Italian adolescents in the age range studied.

Physical activity (PA) is associated with health benefits, already in childhood. However, little is known about actual levels, patterns and gender differences in PA level in very young children. This study examines Chinese one-year-old children and their parents' PA levels and patterns, and assesses the correlations between children's PA level and gender, body mass index standard deviation score (BMI SDS), parental BMI and parental PA level. Data from 123 families participating in the Early STOPP China study were used. Families were recruited based on parental BMI and were classified as either high-risk or low-risk of obesity. Parents and children wore an ActiGraph GT3X+ to assess the average PA levels. PA levels and hourly patterns during weekdays and weekends were examined as were correlations with gender, BMI SDS, parental BMI and parental PA levels. There were no significant differences in children's averaged PA between risk groups, genders, or between weekdays and weekends. Children's peak average activity level was at 7 pm and they were least active at 3 pm (p<0.001). Both mothers and fathers demonstrated a similar PA pattern as their children, although paternal PA level was consistently lower than that of mothers and children. No significant association was found between children's PA and their gender, BMI SDS, parental BMI or paternal PA levels. Maternal PA was found positively associated with child PA (p<0.05). PA in one-year-old Chinese children vary over the day but weekdays and weekends are similar. At this age, children's PA is not related to gender, BMI SDS, parental BMI or paternal PA. Larger scale studies with more contextual information are needed to improve the understanding of our findings.

Fast species diagnosis has an important health care impact, as rapid and specific antibacterial therapy is of clear benefit for patient's outcome. Here, a new protocol for species identification directly from positive blood cultures is proposed. Four in-house protocols for bacterial identification by MS directly from clinical positive blood cultures evaluating two lytic agents, SDS and saponin, and two protein extraction schemes, fast (FP) and long (LP) are compared. One hundred and sixty-eight identification tests are carried out on 42 strains. Overall, there are correct identifications to the species level in 90% samples for the SDS-LP, 60% for the SDS-FP, 48% for the saponin LP, and 43% for the saponin FP. Adapted scores allowed 92, 86, 72, and 53% identification for SDS-LP, SDS-FP, saponin LP, and saponin FP, respectively. Saponin lysis is associated with a significantly lower score compared to SDS (0.87 [0.83-0.92], p-value < 0.001). This study supports the use of SDS lysis instead of saponin lysis and the application of this rapid and cost-effective protocol in daily routine for microbiological agents implicated in septicemia. © 2016 WILEY-VCH Verlag GmbH & Co.

We aimed to determine whether children conceived with ovarian stimulation alone (OS(A)) would differ phenotypically and biochemically from naturally conceived children of fertile and subfertile parents. Healthy pre-pubertal children aged 3-10 years, born at term, after singleton pregnancies were recruited in Auckland (New Zealand) and were allocated into three groups: (i) children conceived following OS(A) and naturally conceived children of (ii) subfertile and (iii) fertile parents. Anthropometric, endocrine and metabolic parameters were recorded. Children's heights and body mass index (BMI) were expressed as standard deviation scores (SDS) and corrected for genetic potential (i.e. parental height or BMI). Three hundred fifty-two children were studied: 84 OS(A) subjects and 268 naturally conceived controls consisting of 54 children of subfertile parents and 214 children of fertile parents. Children of subfertile and fertile parents did not differ in measured outcomes. Overall, OS(A) children were shorter than children of both subfertile (SDS: -0.08 ± 0.09 versus 0.32 ± 0.07; P= 0.001) and fertile (SDS: -0.08 ± 0.09 versus 0.45 ± 0.10; P= 0.004) parents when corrected for genetic height potential. OS(A) boys were shorter than boys of subfertile (SDS:-0.18 ± 0.14 versus 0.42 ± 0.16; P= 0.03) and fertile (SDS: -0.18 ± 0.14 versus 0.35 ± 0.08; P= 0.01) parents. There was also a trend towards OS(A) girls being shorter than girls of subfertile parents (P= 0.06), but not significantly shorter than those of fertile parents (P= 0.17). OS(A) children also had a lower corrected BMISDS than children of subfertile (SDS-0.90 ± 0.15 versus -0.37 ± 0.17; P= 0.06) and fertile (-0.90 ± 0.15 versus -0.34 ± 0.10; P= 0.008) parents. Among metabolic parameters, fasting glucose was lower in OS(A) children than that in children of fertile parents (4.62 ± 0.07 versus 4.81 ± 0.04; P= 0.006). Conception after OS(A) was associated with shorter stature, particularly in boys, compared with naturally conceived children of fertile and subfertile parents.

Spleen-deficiency syndrome (SDS) in Traditional Chinese Medicine (TCM) played pivotal roles on the development of hepatocellular carcinoma (HCC). This study was performed to establish and evaluate HCC model in mice with SDS in TCM. A total of 90 C57BL/6 mice were randomized in six groups (n=15 for each group): A, Control group; B, SDS group; C, orthotopic HCC (OHCC) group; D, OHCC based on SDS (SDS-OHCC) group; E, Drug-induced HCC (DHCC) group; F, DHCC based on SDS (SDS-DHCC) group. The SDS model were established by subcutaneous injection of reserpine, followed by the OHCC or DHCC model establishment. The SDS scores, tumor formation rate and survival time were recorded and calculated, as well as the histochemical stain was performed. The SDS scores of mice in Group B, D, F were 17.57±4.86 (P<0.05 vs. Group A), 18.13±4.53 (P<0.05 vs. Group A and C) and 23.32±4.94 (P<0.05 vs. Group A and E) respectively. The tumor formation rate of mice in Group C, D, E and F were 73.33%, 100%, 60% and 80% respectively. The survival time of mice in Group C, D, E and F were 26.42±5.27, 17.33±4.76 (P<0.05 vs. Group C), 35.77±6.12 and 22.61±5.05 (P<0.05 vs. Group E) respectively. The SDS-oriented HCC mice models were simple and easily-operated models for further studies on SDS oriented tumor. Meanwhile, SDS was a pivotal factor for low outcome of hepatic tumor.

To estimate median urinary iodine concentration (UIC), and to correlate it with global nutrition indicators and social gap index (SGI) in 50 elementary state schools from 10 municipalities in the State of Queretaro, Mexico. 1,544 students were enrolled and an above of requirements of iodine intake was found (median UIC of 297 µg/L). Iodine status was found as deficient, adequate, more than adequate and excessive in 2, 4, 19 and 25 schools, respectively. Seventy seven percent of table salt samples showed adequate iodine content (20-40 ppm), while 9.6% of the samples had low iodine content (< 15 ppm). Medians of UIC per school were positively correlated with medians of body mass index (BMI) by using the standard deviation score (SDS) (r = 0.47; p < 0.005), height SDS (r = 0.41; p < 0.05), and overweight and obesity prevalence (r = 0.41; p < 0.05). Medians of UIC per school were negatively correlated with stunting prevalence (r = -0.39; p = 005) and social gap index (r = -0.36; p < 0.05). Best multiple regression models showed that BMI SDS and height were significantly related with UIC (p < 0.05). There is coexistence between the two extremes of iodine intake (insufficient and excessive). To our knowledge, the observed positive correlation between UIC and overweight and obesity has not been described before, and could be explained by the availability and consumption of snack food rich in energy and iodized salt.

3-M syndrome associated with growth hormone deficiency: 18 year follow-up of a patient

PubMed Central

2013-01-01

3-M syndrome is a rare autosomal recessive disorder that causes short stature, unusual facial features and skeletal abnormalities. Mutations in the CUL7, OBSL1 and CCDC8 genes could be responsible for 3-M syndrome. Here we describe the growth and evolution of dismorphic features of an Italian boy with 3-M syndrome and growth hormone deficiency (GHD) from birth until adulthood. He was born full term with a very low birth weight (2400 g=−3.36 standard deviation score, SDS) and length (40.0 cm =−6.53 SDS). At birth he presented with a broad, fleshy nose with anteverted nostrils, thick and patulous lips, a square chin, curvilinear shaped eyebrows without synophrys, short thorax and long slender bones. Then, during childhood tall vertebral bodies, hip dislocation, transverse chest groove, winged scapulae and hyperextensible joints became more evident and the diagnosis of 3-M syndrome was made; this was also confirmed by the finding of a homozygous deletion in exon 18 of the CUL7 gene, which has not been previously described. The patient also exhibited severe GHD (GH <5 ng/ml) and from the age of 18 months was treated with rhGH. Notwithstanding the early start of therapy and good compliance, his growth rate was always very low, except for the first two years of treatment and he achieved a final height of 132 cm (−6.42 SDS).

The reduction of spontaneous physical activity (PA) and of muscle tissue are thought to be major causes of fat accretion and metabolic deterioration in Prader-Labhart-Willi syndrome (PWS). We investigated whether a generalized physical training programme in a home setting improves these parameters. The prospective study included 11 prepubertal children (mean age 8.7 years, range 5.9-11.8) with documented PWS and under continuous growth hormone treatment for at least 2.8 years. Seven children were enrolled in a training programme for several muscle groups during 4-10 minutes daily. Twelve matched children with PWS served as controls (average age 8.8 years, 6.1-11.3). Before and after training, at 6 months, PA was assessed by measuring walking distance by pedometer registration and by an activity score, and body composition by DEXA expressed as standard deviation scores (SDS) related to height. After training, lean mass (LM) increased from -1.83 to -1.48 SDS, p <0.05, whereas the controls showed no change. In the training group, walking distance and PA increased from 4.2 to 4.7 km/d and from 255 to 266 points, respectively, and these rises significantly exceeded those observed in controls. Children with PWS can be motivated by their families to follow a short daily training, which has general effects on PA and does increase, but not normalize LM.

To describe the meal patterns of Jena schoolchildren and their associations with children's weight status and parental characteristics. Cross-sectional study. Twenty schools in Jena (100,000 inhabitants), south-east Germany. A total of 2054 schoolchildren aged 7-14 years with information on BMI standard deviation score (BMI-SDS) and weight status (based on German reference values), of whom 1571 had additional information about their parents (parental education and employment status, weight status according to WHO guidelines) and meal patterns (school lunch participation rate, meal frequencies, breakfast consumption and frequency of family meals). Weight status of the children was associated with weight status, education and employment status of the parents. Meal patterns were strongly dependent on children's age and parental employment. As age increased, the frequency of meal consumption, participation rate in school lunches and the number of family meals decreased. Using linear regression analysis, a high inverse association between BMI-SDS and meal frequency was observed, in addition to relationships with parental weight status and paternal education. Age-specific prevention programmes should encourage greater meal frequency. The close involvement of parents is essential in any strategy for improving children's (families') diets.

Sleep disorders (SDs) are common in cirrhotics and are often associated with hepatic encephalopathy. SDs negatively affect patients' daily activities and work efficiency. For this reason, early diagnosis is important. The methods used for diagnosis of SDs are not practical and need longer periods of application and evaluation. In this study, we aimed to investigate sleep disorders and related clinical parameters in cirrhosis and also wanted to investigate the using of Sleep Timing and Sleep Quality Screening questionnaire (STSQS), a simple form with a short application time, for diagnosis of SDs and its correlation with Pittsburg Sleep Quality Index (PSQI) form. Cirrhotic patients and age-matched healthy volunteers were enrolled. Patients were excluded from this study if they had neuropsychiatric disease or used excessive alcohol or drugs known to affect sleep. Both groups completed validated Turkish form of PSQI and STSQS. SD was defined as PSQI score (0-21) of >5 or STSQS ≥5. One hundred and thirty-one cirrhotic patients and 18 healthy volunteers were enrolled. SDs in cirrhotics and control group were detected 56.5% and 27.8% by PSQI, 49.6% and 16.7% by STSQS respectively. SDs are the most frequent in the Child C patients, and the least frequent in the Child A patients (P > 0.05). No correlation was found between the MELD score and SDs. SDs were more common in cirrhotic patients with hypoalbuminaemia and low haemoglobin levels. In addition, the patients with decompensated cirrhosis had more frequently SDs than the patients with compensated cirrhosis. In the patient group, sleep latency and total sleep time, sleep parameters were correlated with SDs. STSQS had statistical significant correlation with PSQI for diagnosis of SDs. SDs are common in cirrhotics and STSQS could be an appropriate and practical method for diagnosis of SDS in these patients. We can use it in cirrhotic patients at outpatient clinics. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The objective of this post-hoc analysis was to investigate the relationship between motivation/energy and functional impairment in patients with major depressive disorder (MDD). Data were taken from a phase 3 trial of levomilnacipran extended-release (ER) in adults with MDD (NCT01034462; N=429) that used the 18-item Motivation and Energy Inventory (MEI) to assess motivation/energy. Two subgroups with lower and higher motivation/energy were defined using baseline MEI total scores (≤28 and >28, respectively). Change from baseline in the Sheehan Disability Scale (SDS) total score was analyzed in the intent-to-treat (ITT) population and both subgroups. Path analyses were carried out in the ITT population and a lower MEI subgroup to assess the direct and indirect effects of levomilnacipran ER on SDS total score change. In the ITT population and the lower MEI subgroup, significant differences were found between levomilnacipran ER and placebo for changes in the SDS total score (-2.6 and -3.9, both P<0.01), but not in the higher MEI subgroup. The indirect effect of levomilnacipran ER on SDS total score improvement, as mediated by MEI total score change, was 79.9% in the lower MEI subgroup and 67.2% in the ITT population. Levomilnacipran ER was previously shown to improve motivation/energy in adults with MDD. The current analysis indicates that improvements in functional impairment were considerably mediated by improvements in motivation/energy, particularly in patients with lower motivation/energy at baseline.

The aim of the current study was to evaluate the effects of and adherence to an active video game promotion intervention on anthropometrics, sedentary screen time and consumption of sugar-sweetened beverages and snacks among non-active video gaming adolescents who primarily were of healthy weight. We assigned 270 gaming (i.e. ≥ 2 hours/week non-active video game time) adolescents randomly to an intervention group (n = 140) (receiving active video games and encouragement to play) or a waiting-list control group (n = 130). BMI-SDS (SDS = adjusted for mean standard deviation score), waist circumference-SDS, hip circumference and sum of skinfolds were measured at baseline, at four and ten months follow-up (primary outcomes). Sedentary screen time, physical activity, consumption of sugar-sweetened beverages and snacks, and process measures (not at baseline) were assessed with self-reports at baseline, one, four and ten months follow-up. Multi-level-intention to treat-regression analyses were conducted. The control group decreased significantly more than the intervention group on BMI-SDS (β = 0.074, 95%CI: 0.008;0.14), and sum of skinfolds (β = 3.22, 95%CI: 0.27;6.17) (overall effects). The intervention group had a significantly higher decrease in self-reported non-active video game time (β = -1.76, 95%CI: -3.20;-0.32) and total sedentary screen time (Exp (β = 0.81, 95%CI: 0.74;0.88) than the control group (overall effects). The process evaluation showed that 14% of the adolescents played the Move video games every week ≥ 1 hour/week during the whole intervention period. The active video game intervention did not result in lower values on anthropometrics in a group of 'excessive' non-active video gamers (mean ~ 14 hours/week) who primarily were of healthy weight compared to a control group throughout a ten-month-period. Even some effects in the unexpected direction were found, with the control group showing lower BMI-SDS and skin folds than the intervention group. The intervention did result in less self-reported sedentary screen time, although these results are likely biased by social desirability. Dutch Trial Register NTR3228.

In children with central precocious puberty (CPP), gonadotropin-releasing hormone (GnRH) analogue treatment has been associated with an increase in body mass index (BMI). We evaluated BMI and body composition in adolescents treated with GnRH analogue at their near final height to assess the long-term effects of therapy on these parameters. We studied 20 patients (14.8 +/- 1.6 years; 17 females) previously treated with triptorelin depot for CPP (3.75 mg/28 days) from 8.1 +/- 0.8 to 11.5 +/- 0.8 years. 23 healthy adolescents with normal onset of puberty (14.7 +/- 2.1 years, 19 females) were the controls. BMI and body composition (dual-energy x-ray absorptiometry) were assessed. Patients reached their near adult height (-0.5 +/- 1.1 standard deviation score (SDS)); the girls were menstruating and the majority (15/17) had regular cycles, the boys showed normal testicular function. BMI was unchanged from the start of GnRH analogue therapy (0.4 +/- 1.0 SDS) to near adult height (0.2 +/- 1.0 SDS, p = NS vs. 0). Total fat mass (TFM) was significantly increased (16,144 +/- 8,065 g; controls 10,712.1 +/- 4,120.4 g, p < 0.02); glucose homeostasis and lipid profile corresponded to reference ranges. GnRH analogue therapy did not show long-term detrimental effects on BMI, but it may increase TFM, suggesting that body composition should be monitored till adulthood. Copyright 2009 S.

Idiopathic short stature (ISS) constitutes a heterogeneous group of short stature which is not associated with an endocrine or other identifiable cause. Some ISS patients may have varying degrees of insulin-like growth factor-1 (IGF-1) deficiency. Recombinant growth hormone (rGH) treatment has been used by some authors with variable results. Reports on long-term rGH treatment are limited. In this study, 21 slowly growing, non-GH-deficient ISS children who received rGH treatment for 3.62±0.92 years were evaluated at the end of a 5.42±1.67-year follow-up period. The study group included patients with low IGF-1 levels who also responded well to an IGF generation test. The patients were divided into two groups as good responders [height increment >1 standard deviation (SD)] and poor responders (height increment <1 SD) at the end of the follow-up period. The height of the patients improved from -3.16±0.46 SD score (SDS) to -1.9±0.66 SDS. At the end of the follow-up period, mean height SDS was -1.72. Eleven of the patients showed a good response to treatment. Clinical parameters were essentially similar in the good responders and the poor responders groups. A female preponderance was noted in the good responders group. rGH treatment can safely be used in ISS children. Long-term GH treatment will ameliorate the height deficit and almost 40% of patients may reach their target height.

It has been reported that daily recombinant human growth hormone (GH) treatment showed beneficial effects on growth in prepubertal children with idiopathic short stature (ISS). The present study aimed to validate the GH (Eutropin®) effect on growth promotion and safety after short-term GH treatment. This study was an open-label, multicenter, interventional study conducted at nine university hospitals in Korea between 2008 and 2009. Thirty six prepubertal children with ISS were enrolled in this study to receive 6-month GH treatment. Yearly growth rate, height standard deviation score (SDS), and adverse events were investigated during treatment. After 26 weeks of GH treatment, the height velocity significantly increased by 6.36±3.36 cm/year (p<0.001). The lower end of one-sided 95% confidence interval was 5.22 cm/year, far greater than the predefined effect size. The gain in height SDS at week 26 was 0.57±0.27 (p<0.0001). Bone age significantly increased after GH treatment, however, bone maturation rate (bone age for chronological age) showed limited advancement. This 26-week GH treatment was effective in increasing serum levels of insulin-like growth factor (IGF)-I and IGF binding protein (IGFBP)-3 from baseline (p<0.0001). Eutropin was well tolerated and there were no withdrawals due to adverse events. No clinically significant changes in laboratory values were observed. This 6-month daily GH treatment in children with ISS demonstrated increased height velocity, improved height SDS, and increased IGF-I and IGFBP-3 levels with a favorable safety profile.

Aggrecan, a proteoglycan, is an important component of cartilage extracellular matrix, including that of the growth plate. Heterozygous mutations in ACAN , the gene encoding aggrecan, cause autosomal dominant short stature, accelerated skeletal maturation, and joint disease. The inheritance pattern and the presence of bone age equal to or greater than chronological age have been consistent features, serving as diagnostic clues. From family 1, a 6-year-old boy presented with short stature [height standard deviation score (SDS), -1.75] and bone age advanced by 3 years. There was no family history of short stature (height SDS: father, -0.76; mother, 0.7). Exome sequencing followed by Sanger sequencing identified a de novo novel heterozygous frameshift mutation in ACAN (c.6404delC: p.A2135Dfs). From family 2, a 12-year-old boy was evaluated for short stature (height SDS, -3.9). His bone age at the time of genetic evaluation was approximately 1 year less than his chronological age. Family history was consistent with an autosomal dominant inheritance of short stature, with several affected members also showing early-onset osteoarthritis. Exome sequencing, confirmed by Sanger sequencing, identified a novel nonsense mutation in ACAN (c.4852C>T: p.Q1618X), which cosegregated with the phenotype. In conclusion, patients with ACAN mutations may present with nonfamilial short stature and with bone age less than chronological age. These findings expand the known phenotypic spectrum of heterozygous ACAN mutations and indicate that this diagnosis should be considered in children without a family history of short stature and in children without accelerated skeletal maturation.

Appropriate nutrition during childhood is important for preventing future development of lifestyle-related diseases. The effect of feeding choice on infant growth in Japan is not known. Data from 204 healthy schoolchildren (age, 6-9 years) were obtained retrospectively from their parents by questionnaires. Breast-fed (BF) and formula-fed (FF) groups were defined as those fed only breast milk or formula milk at 4 months of age, respectively. There were 71 children (M/F, 31/40) in BF and 30 (M/F, 19/11) in FF. Anthropometric data at birth, and at 1, 4, 7, 10, 18, and 36 months of age in male and female infants were compared between the groups. In male infants, height was significantly lower at 4 months, bodyweight was lower from 4 to 18 months, and body mass index (BMI) was lower from 10 to 36 months in BF than in FF. The standard deviation scores (SDS) for height, weight and BMI had a similar pattern. No significant differences were observed for these variables for female infants in BF compared with FF. Multiple regression analysis showed that birthweight, mother's pre-pregnancy weight, and infant feeding choice were significant factors associated with weight-SDS at 18 and 36 months. Feeding choice was the only factor associated with BMI-SDS at 18 months. Infant feeding choice had a gender-associated effect on growth during infancy. When evaluating infant growth, not only birthweight and mother's pre-pregnancy weight, but also infant feeding choice and gender should be considered. © 2013 The Authors.

Solubilization of pyrene by anionic-nonionic mixed surfactants.

Zhou, Wenjun; Zhu, Lizhong

Surfactant-enhanced remediation (SER) is an effective approach for the removal of sorbed hydrophobic organic compounds from contaminated soils. The solubilization of pyrene by four anionic-nonionic mixed surfactants, sodium dodecyl sulfate (SDS) with Triton X-405 (TX405), Brij35, Brij58, and Triton X-100 (TX100), has been studied from measurements of the molar solubilization ratio (MSR), the micelle-water partition coefficient (Kmc), and the critical micelle concentration (CMC). The MSRs of pyrene in mixed surfactants are found to be larger than those predicted according to an ideal mixing rule. The mixing effect of anionic and nonionic surfactants on MSR for pyrene follows the order of SDS-TX405 > SDS-Brij35 > SDS-Brij58 > SDS-TX100 and increases with an increase in the hydrophile-lipophile balance (HLB) value of nonionic surfactant in mixed systems. In addition, the mixture of anionic and nonionic surfactants cause the Kmc value for pyrene to be greater than the ideal value in SDS-TX405 mixed system, but to be smaller than the ideal value in SDS-Brij35, SDS-Brij58, and SDS-TX100 mixed systems. Meanwhile, in the four mixed systems, the experimental CMCs are lower than the ideal CMCs at almost all mixed surfactant solution compositions. The mixing effect of anionic and nonionic surfactants on MSR for pyrene can be attributed to the conjunct or the net result of the negative deviation of the CMCs from ideal mixture and the increasing or decreasing Kmc.

Bipolar depression is characterized by depressive symptoms and impairment in many areas of functioning, including work, family, and social life. The objective of this study was to assess the independent, direct effect of lurasidone treatment on functioning improvement, and examine the indirect effect of lurasidone treatment on functioning improvement, mediated through improvements in depression symptoms. Data from a 6-week placebo-controlled trial assessing the effect of lurasidone monotherapy versus placebo in patients with bipolar depression was used. Patient functioning was measured using the Sheehan disability scale (SDS). Descriptive statistics were used to assess the effect of lurasidone on improvement on the SDS total and domain scores (work/school, social, and family life), as well as number of days lost and unproductive due to symptoms. Path analyses evaluated the total effect (β1), as well as the indirect effect (β2×β3) and direct effect (β4) of lurasidone treatment on SDS total score change, using standardized beta path coefficients and baseline scores as covariates. The direct effect of treatment on SDS total score change and indirect effects accounting for mediation through depression improvement were examined for statistical significance and magnitude using MPlus. In this 6-week trial (N = 485), change scores from baseline to 6-weeks were significantly larger for both lurasidone treatment dosage groups versus placebo on the SDS total and all three SDS domain scores (p < 0.05). Through path analyses, lurasidone treatment predicted improvement in depression (β2 = -0.33, p = 0.009), subsequently predicting improvement in functional impairment (β3 = 0.70, p < 0.001; indirect effect = -0.23). The direct effect was of medium magnitude (β4 = -0.17, p = 0.04), indicating lurasidone had a significant and direct effect on improvement in functional impairment, after accounting for depression improvement. Results demonstrated statistically significant improvement in functioning among patients on lurasidone monotherapy compared to placebo. Improvement in functioning among patients on lurasidone was largely mediated through a reduction in depression symptoms, but lurasidone also had a medium and statistically significant independent direct effect in improving functioning.

Background: Anogenital distance (AGD) in animals is a sensitive biomarker of fetal endocrine disruption and the associated testicular dysgenesis syndrome (TDS). However, AGD in human infants with cryptorchidism and hypospadias, which are potential manifestations of TDS during childhood, is not clearly described. Objective: Our aim was to compare AGD in boys with cryptorchidism or hypospadias against normative data. Methods: Boys with isolated cryptorchidism (n = 71, age 13.4 ± 5.8 months) or hypospadias (n = 81, age 11.4 ± 6.2 months) were recruited from a tertiary center for measurement of AGD and penile length; they were compared with 487 healthy full-term boys from a birth cohort by deriving age-specific standard deviation scores (SDS). Results: Boys with cryptorchidism were older (p = 0.048) compared with boys with hypospadias. Boys with hypospadias had shorter mean AGD and penile length SDS than healthy boys (both p < 0.0001). Mean AGD and penile length SDS values in boys with cryptorchidism were longer than mean values in boys with hypospadias (both p < 0.01) and shorter than mean values in healthy boys (both p < 0.0001). Mean penile length SDS decreased as the severity of hypospadias increased (ptrend = 0.078). Conclusions: In the study population, AGD and penile length were reduced in boys with hypospadias or cryptorchidism relative to normative data derived from a longitudinal birth cohort. The findings support the use of AGD as a quantitative biomarker to examine the prenatal effects of exposure to endocrine disruptors on the development of the male reproductive tract.

Introduction The aim was to investigate whether a familial predisposition to obesity related cardiovascular complications was associated with the degree of obesity at baseline and/or changes in the degree of obesity during a multidisciplinary childhood obesity treatment program. Methods The study included 1421 obese children (634 boys) with a median age of 11.5 years (range 3.1–17.9 years), enrolled in treatment for 0.04 to 5.90 years (median 1.3 years) at the Children's Obesity Clinic, Denmark. At baseline, weight and height were measured, body mass index (BMI) standard deviation score (SDS) calculated, and self-reported information on familial predisposition to obesity, hypertension, type 2 diabetes mellitus (T2DM), thromboembolic events, and dyslipidaemia were obtained. A familial predisposition included events in biological parents, siblings, grandparents, uncles, and aunts. The treatment outcomes were categorically analysed according to the prevalence of familial predispositions. Results The median BMI SDS at enrolment was 3.2 in boys and 2.8 in girls. One-thousand-and-forty-one children had obesity in their family, 773 had hypertension, 551 had T2DM, 568 had thromboembolic events, and 583 had dyslipidaemia. Altogether, 733 had three or more predispositions. At baseline, familial T2DM was associated with a higher mean BMI SDS (p = 0.03), but no associations were found between the other predispositions and the children's degree of obesity. During treatment, girls with familial obesity lost more weight, compared to girls without familial obesity (p = 0.04). No other familial predispositions were associated with changes in BMI SDS during treatment. Conclusion Obese children with a familial predisposition to T2DM showed a significantly higher degree of obesity at baseline and girls with familial obesity responded better to treatment. Besides these findings, no other associations were found between the occurrence of familial predispositions and the degree of obesity or changes herein during multidisciplinary childhood obesity treatment.

We have previously reported on a case-series of children (n=46) with suspected calcium-deficiency rickets who presented in The Gambia with rickets-like bone deformities. Biochemical analyses discounted vitamin D-deficiency as an aetiological factor but indicated a perturbation of Ca-P metabolism involving low plasma phosphate and high circulating fibroblast growth factor-23 (FGF23) concentrations. A follow-up study was conducted 5 years after presentation to investigate possible associated factors and characterise recovery. 35 children were investigated at follow-up (RFU). Clinical assessment of bone deformities, overnight fasted 2 h urine and blood samples, 2-day weighed dietary records and 24 h urine collections were obtained. Age- and season-matched data from children from the local community (LC) were used to calculate standard deviation scores (SDS) for RFU children. None of the RFU children had radiological signs of active rickets. However, over half had residual leg deformities consistent with rickets. Dietary Ca intake (SDS-Ca=-0.52 (0.98) p=0.04), dietary Ca/P ratio (SDS-Ca/P=-0.80 (0.82) p=0.0008) and TmP:GFR (SDS-TmP:GFR=-0.48 (0.81) p=0.04) were significantly lower in RFU children compared with LC children and circulating FGF23 concentration was elevated in 19% of RFU children. Furthermore an inverse relationship was seen between haemoglobin and FGF23 (R(2)=25.8, p=0.004). This study has shown differences in biochemical and dietary profiles between Gambian children with a history of rickets-like bone deformities and children from the local community. This study provided evidence in support of the calcium deficiency hypothesis leading to urinary phosphate wasting and rickets and identified glomerular filtration rate and iron status as possible modulators of FGF23 metabolic pathways.

Little is known about post-natal growth in IVF offspring and the effects of rates of early post-natal growth on blood pressure and body fat composition during childhood and adolescence. The follow-up study comprised 233 IVF children aged 8-18 years and 233 spontaneously conceived controls born to subfertile parents. Growth data from birth to 4 years of age, available for 392 children (n = 193 IVF, n = 199 control), were used to study early post-natal growth. Furthermore, early post-natal growth velocity (weight gain) was related to blood pressure and skinfold measurements at follow-up. We found significantly lower weight, height and BMI standard deviation scores (SDSs) at 3 months, and weight SDS at 6 months of age in IVF children compared with controls. Likewise, IVF children demonstrated a greater gain in weight SDS (P < 0.001), height SDS (P = 0.013) and BMI SDS (P = 0.029) during late infancy (3 months to 1 year) versus controls. Weight gain during early childhood (1-3 years) was related to blood pressure in IVF children (P = 0.014 systolic, 0.04 diastolic) but not in controls. Growth during late infancy was not related to skinfold thickness in IVF children, unlike controls (P = 0.002 peripheral sum, 0.003 total sum). Growth during early childhood was related to skinfold thickness in both IVF and controls (P = 0.005 and 0.01 peripheral sum and P = 0.003 and 0.005 total sum, respectively). Late infancy growth velocity of IVF children was significantly higher compared with controls. Nevertheless, early childhood growth instead of infancy growth seemed to predict cardiovascular risk factors in IVF children. Further research is needed to confirm these findings and to follow-up growth and development of IVF children into adulthood.

Serum thyroid stimulating hormone (TSH) levels are frequently elevated in obese children and are most likely to be associated with insulin resistance. However, clinical relevance of this association remains unclear. To assess the prevalence of hyperthyrotropinemia; to analyze the relationship between TSH and homeostasis model assessment - insulin resistance (HOMA-IR); and to verify whether TSH levels and HOMA-IR vary with weight loss in obese children. Retrospective longitudinal study with data from baseline and 1 year after lifestyle intervention in a pediatric obese group (344 children were recruited and 100 among them completed follow-up). For postintervention analysis, three groups were considered according to body mass index-standard deviation score (BMI-SDS) variations: ≤-0.5 (significant weight loss); 0.5-0 (weight loss); and >0 (weight gain). Statistical analysis was performed using SPSS 19.0®. The prevalence of increased TSH levels was 9.3%. At baseline TSH (p=0.007), fT4 (p=0.006), and HOMA-IR (p<0.001) were positively correlated to BMI-SDS (n=344). Weight reduction was verified in 67 out of 100 cases but significant loss was present in only 21 cases. Decreases in both TSH and BMI-SDS were independently associated with decreases in HOMA-IR (p=0.005 and p=0.016, respectively). There was no correlation between TSH and BMI-SDS variation. Significant decreases in the HOMA-IR (p=0.006) were only achieved in the significant weight loss group. The prevalence of hyperthyrotropinemia was lower than previously reported. However, cutoff values were adjusted to pubertal stage, suggesting an over report in other studies. Insulin resistance and TSH were positively correlated, independent of body status. Although weight loss was not associated with TSH variation, a decrease in TSH levels was independently associated with decreases in HOMA-IR.

Few studies have compared the response to growth hormone (GH) treatment between indications such as isolated growth hormone deficiency (IGHD), born small for gestational age (SGA), idiopathic short stature (ISS), and multiple pituitary hormone deficiency (MPHD). The aim of this analysis of data, collected from two large ongoing observational outcome studies, was to evaluate growth and insulin-like growth factor-I (IGF-I) response data for children of short stature with IGHD, MPHD, SGA, or ISS following two years of treatment with the recombinant GH product Norditropin® (Novo Nordisk A/S, Bagsværd, Denmark). Analysis of auxologic data from two ongoing prospective observational studies, NordiNet® International Outcomes Study (NordiNet® IOS) and NovoNet®/American Norditropin® Web-enabled Research (ANSWER) Program®. 4,582 children aged <18 years were included: IGHD, n = 3,298; SGA, n = 678; ISS, n = 334; and MPHD, n = 272. After two years' GH treatment, change in height standard deviation score (SDS) was +1.03 in SGA and +0.84 in ISS vs. +0.97 in IGHD (p = 0.047; p < 0.001 vs. IGHD, respectively). Height gain was comparable between IGHD and MPHD. In pre-pubertal children vs. total population, height SDS change after two years was: IGHD, +1.24 vs. +0.97; SGA, +1.17 vs. +1.03; ISS, +1.04 vs. +0.84; and MPHD, +1.16 vs. +0.99 (all p < 0.001). After two years' GH treatment, change in height SDS was greater in SGA and less in ISS, compared with IGHD; the discrepancy in responses may be due to the disease nature or confounders (i.e. age). Height SDS increase was greatest in pre-pubertal children, supporting early treatment initiation to optimize growth outcomes.

There is little adult height data in patients with familial male-limited precocious puberty (FMPP) and no management consensus. We assessed the treatment and adult height in local patients with FMPP and those reported in the literature. Growth data were obtained on four local patients with FMPP and a search performed to obtain management details and adult height data on cases in the literature. UK (90) population standards were used to calculate standard deviation scores (SDS). Adult height data were available on 25 men with FMPP of whom 21 were treated. Median adult height SDS of patients was -1.5 SD with a mid-parental target of -0.6 SD (p=0.1). Eight patients (32%) had an adult height above the mid-parental target and seven patients (28%) had a height >2 SD below the mean. The median height SD was -0.03 in untreated patients and +0.5 SD in those receiving an aromatase inhibitor. There was no relationship between height and age at presentation. Aromatase inhibitor therapy is associated with a positive height outcome in FMPP but the outcome with and without intervention is unpredictable. Clinicians need to be cautious when counselling families about the potential height outcome in FMPP.

A flow cytometric procedure for determining mitotic index (MI) as part of the metaphase chromosome aberrations assay, developed and utilized routinely at Pfizer as part of their standard assay design, has been adopted successfully by Covance laboratories. This method, using antibodies against phosphorylated histone tails (H3PS10) and nucleic acid stain, has been evaluated by the two independent test sites and compared to manual scoring. Primary human lymphocytes were treated with cyclophosphamide, mitomycin C, benzo(a)pyrene, and etoposide at concentrations inducing dose-dependent cytotoxicity. Deming regression analysis indicates that the results generated via flow cytometry (FCM) were more consistent between sites than those generated via microscopy. Further analysis using the Bland-Altman modification of the Tukey mean difference method supports this finding, as the standard deviations (SDs) of differences in MI generated by FCM were less than half of those generated manually. Decreases in scoring variability owing to the objective nature of FCM, and the greater number of cells analyzed, make FCM a superior method for MI determination. In addition, the FCM method has proven to be transferable and easily integrated into standard genetic toxicology laboratory operations. Copyright © 2012 Wiley Periodicals, Inc.

Data from a study concerning retention interval and school-meal observation on children's dietary recalls were used to investigate relationships of social desirability score (SDS) and body mass index percentile (BMI%) to recall accuracy for energy for observed (n = 327) children, and to reported energy for observed and unobserved (n = 152) children. Report rates (reported/observed) correlated negatively with SDS and BMI%. Correspondence rates (correctly reported/observed) correlated negatively with SDS. Inflation ratios (overreported/observed) correlated negatively with BMI%. The relationship between reported energy and each of SDS and BMI% did not depend on observation status. Studies utilizing children's dietary recalls should assess SDS and BMI%.

The aim of the present study was to evaluate the GH status in children with familial, idiopathic short stature (FSS). To this goal we evaluated the GH response to GHRH (1 microg/kg iv) + arginine (ARG) (0.5 g/kg iv) test which is one of the most potent and reproducible provocative tests of somatotroph secretion, in 67 children with FSS [50 boys and 17 girls, age 10.8+/-0.4 yr, pubertal stages I-III, height between -3.6 and -1.6 standard deviation score (SDS), target height <10 degrees centile, normality of both spontaneous and stimulated GH secretion as well as of IGF-I levels]. The results in FSS were compared with those in groups of children of normal height (NHC) (42 NHC, 35 boys and 7 girls, age 12.0+/-0.5 yr, pubertal stages I-III, height between -1.3 and 1.4 SDS, height velocity standard deviation score (HVSDS)>25 degrees centile, GH peak >20 microg/l after GHRH+ARG test, mean GH concentration [mGHc]>3 microg/l) and children with organic GH deficiency (GHD) (38 GHD, 29 boys and 9 girls, age 11.2+/-3.7 yr, pubertal stages I-III, height between -5.7 and -1.3 SDS, GH peak <20 microg/l after GHRH +ARG test, mGHc <3 mg/l). Basal IGF-I levels and mGHc were also evaluated in each group over 8 nocturnal hours. IGF-I levels in FSS (209.2+/-15.6 microg/l) were similar to those in NHC (237.2+/-17.2 microg/l) and both were higher (p<0.0001) than those in GHD (72.0+/-4.0 microg/l). The GH response to GHRH +ARG test in FSS (peak: 66.4+/-5.6 microg/l) was very marked and higher (p<0.01) than that in NHC (53.3+/-4.5 microg/l) which, in turn, was higher (p<0.01) than in GHD (8.2+/-0.8 microg/l). Similarly, the mGHc in FSS was higher than in NHC (6.7+/-0.5 microg/l vs 5.1+/-0.7 microg/l, p<0.05) which, in turn, was higher than in GHD (1.5+/-0.2 microg/l, p<0.0001). In conclusion, our present study demonstrates that short children with FSS show enhancement of both basal and stimulated GH secretion but normal IGF-I levels. These findings suggest that increased somatotroph function would be devoted to maintain normal IGF-I levels thus reflecting a slight impairment of peripheral GH sensitivity in FSS.

Growth hormone (GH) treatment for children with GH deficiency (GHD) is effective in improving adult height. To achieve favorable effects, GH treatment before puberty is very important, because prepubertal height gain is highly correlated with total height gain. However, no report has studied the effects by analyzing a nationwide data from recent GHD patients in Japan. We investigated the response to GH treatment using data compiled in the Foundation for Growth Science in Japan, and compared the effects between the 1990s and 2000s using analysis of covariance. We analyzed 534 prepubertal GHD subjects treated in the 2000s with three consecutive years of data from the start and investigated predictive factors for the effects. The cumulative height standard deviation score (SDS) change over three years of GH treatment was 0.91 ± 0.57 and 1.20 ± 0.62 in the 1990s and 2000s, respectively. Subjects in the 2000s were divided into three groups by severity, and the cumulative height SDS was 1.60 ± 0.93, 1.20 ± 0.54, and 1.00 ± 0.40 indicating severe, moderate, and mild GHD, respectively. Age and height SDS at the start and severity were identified as independent predictive factors. We also found a significant difference in the effects between the two cohorts after adjusting for the different factors (regression coefficient: -0.069, 95% confidence interval: -0.11 to -0.030, p = 0.0006), which might be due to the GH dose effect. We conclude that the effects of GH treatment in the 2000s had improved compared with those in the 1990s.

Chronic infections and liver diseases may influence the growth and development of children by leading to malnutrition. In this study, demographic characteristics, anthropometric measurements and laboratory findings for children with hepatitis B positivity were analyzed. A total of 43 cases were admitted to our clinic between January 2012 and February 2013 and detected to have HBsAg positivity. Malnutrition was detected in 11 cases (25.6%) and obesity in three cases (6.9%). Aspartate aminotransferase (AST) levels were significantly higher in malnourished patients compared to those without malnutrition. The weight to height was significantly higher in patients with positive HBeAg compared to children with negative HBeAg. We found that the weight standard deviation scores (SDS) ratios dropped as alanine aminotransferase (ALT) and AST levels increased and height SDS ratios decreased. In addition, body mass index (BMI) decreased as AST and alpha feto protein (AFP) values increased. While a significant relationship was not detected between insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) and ALT, a significantly negative correlation was detected between IGFBP-3 and IGF-1 and AST. We found a malnutrition rate of 25.6% in children with HBsAg positivity. We also found that weight and height SDS rates decreased as ALT and AST levels increased. In addition, we detected that BMI decreased as AST and AFP values increased. We consider that hepatic inflammation is the factor that affects growth. Monitoring of growth and development during follow-up of children who are detected to have HBsAg positivity would be beneficial to determine the mechanism and causes of growth retardation.

In anorexia nervosa (AN) hypercortisolism has been described using urine, plasma and saliva samples as short-term markers for the hypothalamic-pituitary-adrenal (HPA)-axis. Here, for the first time, we analyse hair cortisol concentration (HCC) as a marker for long-term integrated cortisol secretion in female patients with AN compared to female healthy controls (HC) and female psychiatric controls (PC). HCC was assessed in 22 female adolescent psychiatric inpatients with AN compared to 20 female HC and to 117 female PC of the same age range. For further analyses we examined the associations of age and body mass index (BMI) with HCC. Log HCC was lower in AN-patients compared to HC (p = 0.030). BMI-standard deviation scores (SDS) but not age correlated with log HCC (BMI-SDS: r = 0.19, bias corrected accelerated 95% confidence interval: [.04, .34], p = 0.015; age: r = 0.10, bias corrected accelerated 95% confidence interval: [-.07, .25], p = 0.213) when combining AN, HC and PC samples. We find lower HCC in AN, compared to HC and PC, respectively. Based on the relationship between HCC and BMI-SDS across AN, HC and PC, we argue that HCC might not capture endocrine alterations because of AN pathology-related processes but rather shows consistent relationships with BMI, which extent even to the very low range of BMI values, as present in AN patients. Alternatively, incorporation of cortisol into the hair follicle might have been compromised because of trophic hair follicle disturbances that had been reported in AN patients, previously.

The aim of this study was to investigate the effect of gastrostomy tube feeding on body protein and bone mineralization in malnourished children with cerebral palsy (CP). Children aged between 4 and 18 years with spastic quadriplegic CP (Gross Motor Function Classification System level V) were recruited from the Children's Hospital at Westmead to participate in this prospective cohort study. The children had measurements of anthropometry (weight, height, and skinfold), bone mineral content (BMC) by dual-energy X-ray absorptiometry, and total body protein (TBP) by neutron activation analysis before and after gastrostomy tube feeding. Comparison data were collected prospectively from age-matched healthy children and extracted from databases for this study. A total of 21 children (nine females, 12 males) participated in the study (median age 8 y 5 mo; interquartile range [IQR] 6 y 9 mo-11 y 10 mo). The median length of time of gastrostomy feeding was 19.4 months (IQR 7.7-29.9 mo). Significant (p<0.05) improvements were found in the median values for weight (15.4-23.3 kg), weight standard deviation scores (SDS; -4.8 to -3.0), height (105.4-118.3 cm), per cent body fat (10.7-16.3), TBP (2.4-3.4 kg), TBP per cent predicted for height (83.4-99.0), and BMC (469-626 g). No significant increases were found in height SDS, TBP per cent predicted for age, or BMC SDS for age or height. Malnourished children with quadriplegic CP showed significant increases in body fat and protein with gastrostomy tube feeding. No significant change in bone mineralization predicted for age or height was observed. © The Authors. Journal compilation © Mac Keith Press 2010.

To treat children born small for gestational age (SGA) with severe short stature, treatment with growth hormone (GH) has been approved in the USA, Europe, and Japan, but no population-based studies have reported their prevalence. The aims of this study were to investigate the prevalence of SGA and short stature in children born SGA who qualify for GH treatment at 3 years of age in a Japanese population. A population-based study was conducted in Kobe, Japan with 27 228 infants who were born between 2006 and 2008 and followed until 3 years of age. Prevalence of birthweight (BW) or birth length (BL) ≤ -2.0 standard deviation scores (SDS) for gestational age (GA; definition of SGA) was calculated. Short children born SGA who qualify for GH treatment at 3 years of age were estimated using the following criteria: BW and BL below the 10th percentile for GA, BW or BL ≤ -2.0 SDS for GA, and 2.5 SDS below the mean height for age. The prevalence of SGA was 3.5%. The estimated prevalence of short stature in children born SGA who met the criteria for GH treatment was 0.06%. The prevalence in infants born <34 weeks (0.39%) was significantly higher than that in infants born 34-41 weeks GA (0.05%, P = 0.02). The prevalence of SGA and short stature in children born SGA who qualify for GH treatment is approximately 1 of 30 infants and 1 of 1800 children, respectively. The risk is increased when children are born <34 weeks GA. © 2015 Japan Pediatric Society.

Persistent moderate or severe unipolar depression is common and expensive to treat. Clinical guidelines recommend combined pharmacotherapy and psychotherapy. Such treatments can take up to 1 year to show an effect, but no trials of suitable duration have been done. We investigated the efficacy and cost-effectiveness of outpatient-based, specialist depression services (SDS) versus treatment as usual (TAU) on depression symptoms and function. We did a multicentre, single-blind, patient-level, parallel, randomised controlled trial (RCT), as part of the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) study, in three mental health outpatient settings in England. Eligible participants were in secondary care, were older than 18 years, had unipolar depression (with a current major depressive episode, a 17-item Hamilton Depression Rating Scale [HDRS17] score of ≥16, and a Global Assessment of Function [GAF] score of ≤60), and had not responded to 6 months or more of treatment for depression. Randomisation was stratified by site with allocation conveyed to a trial administrator, with research assessors masked to outcome. Patients were randomised (1:1) using a computer-generated pseudo-random code with random permuted blocks of varying sizes of two, four, or six to either SDS (collaborative care approach between psychiatrists and cognitive behavioural therapists for 12 months, followed by graduated transfer of care up to 15 months) or to the TAU group. Intention-to-treat primary outcome measures were changes in HDRS17 and GAF scores between baseline and 6, 12, and 18 months' follow-up. We will separately publish follow-up outcomes for months 24 and 36. Clinical efficacy and cost-effectiveness were examined from health and social care persp ectives at 18 months, as recommended by the National Institute for Health and Care Excellence. This trial is registered at ClinicalTrials.gov (NCT01047124) and the ISRCTN registry (ISRCTN10963342); the trial has ended. 307 patients were assessed for eligibility between Dec 21, 2009, and Oct 31, 2012. 94 patients were assigned to TAU and 93 patients to SDS, and were included in intention-to-treat analyses. The changes from baseline to 6 months in HDRS17 and GAF scores did not significantly differ between treatment groups (mean change difference in HDRS17 score -1·01 [95% CI -3·30 to 1·28], p=0·385; and in GAF score 1·33 [-2·92 to 5·57], p=0·538). Primary outcome data were available for 134 (72%) patients at 12 months. We noted no differences at 12 months' follow-up between SDS and TAU for mean HDRS17 score (14·8 [SD 7·9] in the SDS group vs 17·2 [7·3] in the TAU group, p=0·056) or GAF score (60·4 [11·7] vs 55·8 [12·7], p=0·064), and the changes from baseline to 12 months in HDRS17 and GAF scores did not significantly differ between treatment groups (mean change difference in HDRS17 score -2·45 [95% CI -5·04 to 0·14], p=0·064; and in GAF score 4·12 [-0·11 to 8·35], p=0·056). The mean change in HDRS17 score from baseline to 18 months was significantly improved in the SDS group compared with the TAU group (13·6 [SD 8·8] in the SDS group vs 16·1 [6·6] in the TAU group; mean change difference -2·96 [95% CI -5·33 to -0·59], p=0·015), but the GAF scores showed no significant differences between the groups (61·2 [SD 13·0] vs 57·7 [11·9]; mean change difference 3·82 [-9·3 to 8·57], p=0·113). We reported no deaths, but one (1%) patient was admitted to hospital for myocardial infarction, and three episodes of self-harm were reported in three (2%) patients (two receiving TAU, one receiving SDS care). The incremental cost-effectiveness ratio of SDS versus TAU was £43 603 per quality-adjusted life-year. Compared with usual specialist mental health secondary care, SDS might improve depression symptoms for patients with persistent moderate to severe depression, but functional outcomes and economic benefits are equivocal.

Community-based services such as telephone support lines can provide valuable informational, emotional, and practical support for cancer patients via telephone- or Web-based (live chat or email) platforms. However, very little rigorous research has examined the efficacy of such services in improving patient outcomes. This study will determine whether: proactive telephone or Web-delivered support produces outcomes superior to printed information; and Web-delivered support produces outcomes comparable to telephone support. A consecutive sample of 501 lung cancer outpatients will be recruited from 50 Australian health services to participate in a patient-randomized controlled trial (RCT). Eligible individuals must: be 18 years or older; have received a lung cancer diagnosis (including mesothelioma) within the previous 4 months; have an approximate life expectancy of at least 6 months; and have Internet access. Participants will be randomly allocated to receive: (1) an information booklet, (2) proactive telephone support, or (3) proactive Web support, chat, and/or email. The primary patient outcomes will be measured by the General Health Questionnaire (GHQ-12) and Health Education and Impact Questionnaire (heiQ) at 3 and 6 months post recruitment. The acceptability of proactive recruitment strategies will also be assessed. It is hypothesized that participants receiving telephone or Web support will report reduced distress (GHQ-12 scores that are 0.3 standard deviations (SD) lower) and greater self-efficacy (heiQ scores that are 0.3 SDs higher) than participants receiving booklets. Individuals receiving Web support will report heiQ scores within 0.29 SDs of individuals receiving telephone support. If proven effective, electronic approaches such as live-chat and email have the potential to increase the accessibility and continuity of supportive care delivered by community-based services. This evidence may also inform the redesigning of helpline-style services to be effective and responsive to patient needs.

 Results: In comparison, EPQ scores, scores of extraversion (E) factor in patients with CHE were significantly lower than those in NC subjects (P<0.01), but scores of neuroticism (N) factor in patients with CHE were significantly higher than those in NC subjects (P<0.01), while there was no significant difference in scores of psychoticism (P) and lie (L) factors between two groups (P>0.05). Patients with CHE had significantly higher scores in SDS and SAS compared with the NC subjects (P<0.01). Patients with CHE had significantly higher scores in scale of morbid, physical, social, psychological, general quality of life, and total scores of EQOLS compared with the NC subjects (P<0.01). The level of skin lesions and the degree of itch were significantly correlated with scores in scale SDS, SAS, morbid, physical, social, psychological, general quality of life, and total scores of EQOLS compared with the NC subjects (P<0.05).
 Conclusion: Personality of patients with CHE is prone to emotional instability of introverts.Patients with CHE have a higher level of depression and anxiety, and exert a negative effect on their quality of life, which is related to severity of disease.

In this study, we investigated the effects of GH treatment in children with Down syndrome who had been diagnosed with GH deficiency (GHD). A total of 20 subjects were investigated in this study. Fourteen Down syndrome children (5 boys and 9 girls) with short stature due to GHD were treated with GH at Okayama Red Cross General Hospital, and 6 Down syndrome children (4 boys and 2 girls) with short stature due to GHD were registered in the Pfizer International Growth Database (KIGS). Height SD score (SDS) increased throughout the three-year GH treatment period. The overall mean height SDS increased from -3.5 at baseline to -2.5 after 3 yr of treatment. The mean change in height SDS during these 3 yr was 1.1. In addition, height assessment of SD score based on Down syndrome-specific growth data in the Japanese population revealed that the height SDS (Down syndrome) also increased across the 3-yr GH treatment period. The mean change in height SDS (Down syndrome) during these three years was 1.3. GH therapy was effective for Down syndrome short stature accompanied by GHD, and no new safety concerns were found in this study.

Greater infant weight gain is associated with lower lung function and increased risk of childhood asthma. The role of early childhood peak growth patterns is unclear. We assessed the associations of individually derived early childhood peak growth patterns with respiratory resistance, fractional exhaled nitric oxide, wheezing patterns, and asthma until school-age. We performed a population-based prospective cohort study among 5364 children. Repeated growth measurements between 0 and 3 years of age were used to derive standard deviation scores (s.d.s) of peak height and weight velocities (PHV and PWV, respectively), and body mass index (BMI) and age at adiposity peak. Respiratory resistance and fractional exhaled nitric oxide were measured at 6 years of age. Wheezing patterns and asthma were prospectively assessed by annual questionnaires. We also assessed whether any association was explained by childhood weight status. Greater PHV was associated with lower respiratory resistance [Z-score (95% CI): -0.03 (-0.04, -0.01) per s.d.s increase] (n = 3382). Greater PWV and BMI at adiposity peak were associated with increased risks of early wheezing [relative risk ratio (95% CI): 1.11 (1.06, 1.16), 1.26 (1.11, 1.43), respectively] and persistent wheezing [relative risk ratio (95% CI): 1.09 (1.03, 1.16), 1.37 (1.17, 1.60), respectively] (n = 3189 and n = 3005, respectively). Childhood weight status partly explained these associations. No other associations were observed. PWV and BMI at adiposity peak are critical for lung developmental and risk of school-age wheezing. Follow-up studies at older ages are needed to elucidate whether these effects persist at later ages. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Gestational diabetes mellitus (GDM) is reported to be associated with childhood obesity, however the magnitude of this association and relation to intrauterine growth is uncertain. We, therefore, aimed to assess whether the growth trajectories of large for gestational age (LGA) and non-LGA offspring of mothers with GDM (OGDM) are different until early adolescence. We also aimed to explore whether growth trajectories of OGDM differ from those of offspring of mothers with type 1 or 2 diabetes (ODM1, ODM2). We studied height and BMI standard deviation score (SDS) of the OGDM group, up to the age of 14 years, with subgroup analysis comparing LGA with non-LGA at birth as a reflection of the intrauterine environment. All mothers with GDM who delivered at the University Medical Center Utrecht between 1990 and 2006 were contacted to participate; informed consent was received for 104 OGDM of 93 mothers. Offspring data were collected through Dutch infant welfare centres. Recorded height and weight were converted to BMI and age- and sex-specific SDS values for Dutch children. Additionally, we compared the OGDM group with ODM1 and ODM2 groups in order to identify those offspring with the highest risk of becoming overweight. Growth trajectories were compared between non-LGA and LGA OGDM and between OGDM, ODM1 and ODM2, using a random-effects model. In the longitudinal follow-up a mean of 7.4 ± 2 measurements per infant were available. Mothers had a prepregnancy BMI of 25.8 kg/m 2 and 24% of their infants were LGA at birth. Heights of OGDM were no different from those of the Dutch Growth Study. Non-LGA OGDM showed a BMI SDS comparable with that of the reference population, with a slight increase in early adolescence. LGA OGDM had a higher BMI SDS trajectory than non-LGA OGDM and the reference population, which plateaued at around 10 years of age. Comparison of growth trajectories of OGDM, ODM1 and ODM2 showed ODM2 to have the highest trajectory followed by ODM1 and OGDM, with the LGA counterparts of all three offspring groups in the highest BMI SDS ranges. Until early adolescence, OGDM have a BMI that is 0.5 SDS higher than that of the Dutch background population. LGA OGDM appear to be at particularly higher risk of being overweight in adolescence compared with non-LGA OGDM, putting them also at a higher lifetime risk of being overweight and developing obesity. ODM2 showed the highest BMI SDS values and had an average BMI SDS of +1.6 until the age of 14, when it became +2 SD. These results emphasize the importance of adequate recognition and timely treatment of maternal gestational diabetes to prevent fetal macrosomia in obstetrics.

Simpson biplane method and 3D by transthoracic echocardiography (TTE), radionuclide angiography (RNA) and cardiac magnetic resonance imaging (CMR) are the most accepted techniques for left ventricular ejection fraction (LVEF) assessment. Wall motion score index (WMSI) by TTE is an accepted complement. However, the conversion from WMSI to LVEF is obtained through a regression equation, which may limit its use. In this retrospective study, we aimed to validate a new method to derive LVEF from the wall motion score in 95 patients. The new score consisted of attributing a segmental EF to each LV segment based on the wall motion score and averaging all 16 segmental EF into a global LVEF. This segmental EF score was calculated on TTE in 95 patients, and RNA was used as the reference LVEF method. LVEF using the new segmental EF 15-40-65 score on TTE was compared to the reference methods using linear regression and Bland-Altman analyses. The median LVEF was 45% (interquartile range 32-53%; range from 15 to 65%). Our new segmental EF 15-40-65 score derived on TTE correlated strongly with RNA-LVEF ( r  = 0.97). Overall, the new score resulted in good agreement of LVEF compared to RNA (mean bias 0.61%). The standard deviations (s.d.s) of the distributions of inter-method difference for the comparison of the new score with RNA were 6.2%, indicating good precision. LVEF assessment using segmental EF derived from the wall motion score applied to each of the 16 LV segments has excellent correlation and agreement with a reference method. © 2018 The authors.

Objective The aim of the current study was to evaluate the effects of and adherence to an active video game promotion intervention on anthropometrics, sedentary screen time and consumption of sugar-sweetened beverages and snacks among non-active video gaming adolescents who primarily were of healthy weight. Methods We assigned 270 gaming (i.e. ≥2 hours/week non-active video game time) adolescents randomly to an intervention group (n = 140) (receiving active video games and encouragement to play) or a waiting-list control group (n = 130). BMI-SDS (SDS = adjusted for mean standard deviation score), waist circumference-SDS, hip circumference and sum of skinfolds were measured at baseline, at four and ten months follow-up (primary outcomes). Sedentary screen time, physical activity, consumption of sugar-sweetened beverages and snacks, and process measures (not at baseline) were assessed with self-reports at baseline, one, four and ten months follow-up. Multi-level-intention to treat-regression analyses were conducted. Results The control group decreased significantly more than the intervention group on BMI-SDS (β = 0.074, 95%CI: 0.008;0.14), and sum of skinfolds (β = 3.22, 95%CI: 0.27;6.17) (overall effects). The intervention group had a significantly higher decrease in self-reported non-active video game time (β = -1.76, 95%CI: -3.20;-0.32) and total sedentary screen time (Exp (β = 0.81, 95%CI: 0.74;0.88) than the control group (overall effects). The process evaluation showed that 14% of the adolescents played the Move video games every week ≥1 hour/week during the whole intervention period. Conclusions The active video game intervention did not result in lower values on anthropometrics in a group of ‘excessive’ non-active video gamers (mean ~ 14 hours/week) who primarily were of healthy weight compared to a control group throughout a ten-month-period. Even some effects in the unexpected direction were found, with the control group showing lower BMI-SDS and skin folds than the intervention group. The intervention did result in less self-reported sedentary screen time, although these results are likely biased by social desirability.

In this study, the authors' goal was to compare head circumference in hydrocephalic children during the first 4 years of ventriculoperitoneal (VP) shunt treatment with data on healthy children and to investigate predictors of skull growth in children with a VP shunt. Children from western Sweden treated for hydrocephalus with an initial VP shunt insertion performed between 2001 and 2006 who were younger than 12 months of age at the time of surgery were included. Children with major brain malformations, craniofacial syndromes, large cysts, and tumors were excluded. Head circumference, weight, and height at 9 defined ages up to 4 years were obtained and compared with data from a reference population of 3650 healthy children using the standard deviation score (SDS). Predictors (length, weight, etiology of hydrocephalus, valve type, number of revisions, valve setting, number of adjustments, and time of first surgery) for head circumference SDS and changes in head circumference SDS from shunt insertion at 1 year to last measurement were analyzed using bivariate and multiple linear regression analysis. Fifty children were included. The mean SDSs for head circumference in shunt-treated compared with healthy children were 1.95 ± 2.50 at shunt insertion (p < 0.001, n = 44), 0.38 ± 1.97 at 1 year (p = 0.27, n = 33), -0.96 ± 2.05 at 2 years (p = 0.046, n = 21), -1.39 ± 2.25 at 3 years (p = 0.026, n = 16), and 0.63 ± 3.34 at 4 years (p = 0.73, n = 4). Significant predictors for low head circumference SDS at 1 year of age were low weight (p = 0.002) and short height (p = 0.022) and at last measurement low weight (p < 0.0001), short height (p = 0.002), and 1-4 shunt revisions (p = 0.034). A significant predictor for change in head circumference SDS from shunt insertion to 1 year of age was the number of shunt valve revisions (p = 0.04) and at last measurement an etiology of intraventricular hemorrhage (p = 0.0058). Shunt-treated children have smaller head circumferences at 2 and 3 years of age than healthy children. Low weight, short height, etiology of intraventricular hemorrhage, and frequent shunt valve revisions are predictors for decreased head circumference. Prospective, randomized studies comparing skull growth using fixed and adjustable pressure-regulated shunt valves and flow-regulated valves are needed.

Many modern pesticides have endocrine disrupting abilities and early-life exposure may affect growth and disease risk later in life. Previously, we reported associations between prenatal pesticide exposure and higher childhood body fat content measured by anthropometry. The associations were affected by child PON1 Q192R genotype. We aimed to study whether prenatal pesticide exposure was still associated with body fat content and distribution in the children at puberty and the potential impact of both maternal and child PON1 Q192R genotype. In this prospective cohort study of 247 children born by occupationally exposed or unexposed women (greenhouse workers and controls) two follow-up examinations (age 10-15 and 11-16 years) including simple anthropometry, skinfold measurements, pubertal staging and blood sampling were performed. Total and regional fat% was determined by dual X-ray absorptiometry (DXA) at age 10-15. Prenatal pesticide exposure was associated with increased total, android, and gynoid fat percentage (DXA) at age 10-15 years after adjustment for sex, socioeconomic status, and puberty (all β = 0.5 standard deviation score (SDS) p < 0.05). Stratified by sex, the associations were significant in girls (total fat: β = 0.7 SDS, android-gynoid ratio: β = 0.1, both p < 0.05), but not in boys. Carrying the R-allele (child or mother, separately, or both) augmented the differences between exposed and unexposed children (total fat: β = 1.0 SDS, β = 0.8 SDS, p < 0.05, respectively, and β = 1.2 SDS, p < 0.01). No exposure-related differences were found if either the child or mother had the QQ wild-type. At age 11-16, exposed children tended to have a higher total fat% estimated by skinfolds than unexposed children (p = 0.06). No significant associations between prenatal exposure and body mass index or waist circumference were found. Prenatal pesticide exposure was associated with higher adolescent body fat content, including android fat deposition, independent of puberty. Girls appeared more susceptible than boys. Furthermore, the association depended on maternal and child PON1 Q192R genotype. © 2016 American Society of Andrology and European Academy of Andrology.

Cystic fibrosis-related diabetes mellitus (CFRD) is an increasingly common complication of cystic fibrosis. CFRD is preceded by a progressive decline in insulin secretion but there is no accepted definition of the prediabetic state in CFRD. This prediabetic state appears to have adverse effects on clinical status, nutrition and lung function, but there is no direct evidence that the impaired glucose homeostasis is the cause of these deteriorations. This study examined the prevalence of glucose intolerance and impaired insulin secretion in a population of children with CF without CFRD. Severe CF lung disease is often associated with poor weight gain and slower growth but the mechanism for this is still unclear. The relationships between the current state of glucose homeostasis, insulin secretion and the insulin-like growth factor axis, height velocity, nutrition status and lung function were therefore studied. Eighteen children with cystic fibrosis aged 9.5-15 years had oral glucose tolerance tests and 14 of these also had intravenous glucose tolerance tests (four refused). Blood samples were collected for insulin, C-peptide, glucose, HbA1c, insulin-like growth factor (IGF)-I, IGF-II, IGF-binding protein (IGFBP)-1 and IGFBP-3. Data on height, weight, puberty status, clinical score (Shwachman score) and lung function were recorded. Height velocity, height and weight standard deviation scores (SDS) were calculated using WHO/CDC data. The mean height SDS (-0.52 +/- 0.17) was less than the normal population (P = 0.007) and the mean height velocity was 4.6 +/- 0.5 cm/year, 39% with a height velocity less than the third percentile for age. The weight SDS and body mass index (BMI) were similar to the normal population. Four children had impaired glucose tolerance. The first-phase insulin response (FPIR) was below the first percentile of normal population values in nine (65%). Impaired FPIR or impaired glucose tolerance did not correlate with the Shwachman score, nutritional status or pulmonary function. There was a significant positive correlation between insulin secretion (area under the curve) and height velocity (P = 0.001) and serum IGFBP-3 levels (P = 0.001). Impaired glucose tolerance was present in 20% of children with cystic fibrosis. Impaired insulin secretion was common (65%) even in children with normal glucose tolerance. The mean height SDS for the group was low and the height velocity was abnormally slow in 39%, yet nutritional status as measured by BMI was appropriate for age. Relative insulin deficiency rather than nutritional deprivation or poor clinical status thus appears to be implicated in the poor linear growth of these children with relatively stable lung disease. This was a small study and firm conclusions on this chronic suppurative disease as to the cause of poor growth are not possible. The causes of poor growth are likely to be complex; nevertheless, the apparent decrease in insulin secretion combined with the expected increased demands on insulin production during pubertal growth raises the question as to whether insulin therapy should be considered in children with cystic fibrosis before the onset of cystic fibrosis-related diabetes mellitus.

Obesity, a critical component of metabolic syndrome (MetS), is associated with depression. Deficiency of brain-derived neurotrophic factor (BDNF) is involved in the mechanism of depression. We hypothesized that weight reduction would improve depressive symptoms via increasing BDNF levels in obese men. Male adults with obesity were enrolled in a weight-reduction program for twelve weeks. All subjects underwent daily caloric restriction and an exercise program which was regularly assessed in group classes. Fasting blood samples and Zung Self-Rating Depression Scale (Zung SDS) scores were collected for assessments before and after the study. A total of 36 subjects completed this program. The average reduction in body weight was 8.4 ± 5.1 kg (8.8 ± 5.1%, P < 0.001). Fasting serum BDNF significantly increased after the study (from 40.4 ± 7.8 to 46.9 ± 8.9 ng/ml, P < 0.001). However, the depression symptoms, as assessed by the Zung Self-Rating Depression Scale (Zung SDS), did not reduce significantly (P = 0.486). Divided into subgroups based on changes in BDNF, Zung SDS scores were significantly reduced in subjects with greater BDNF increase than in those with minor BDNF change (-3.9 ± 6.2 vs. 2.3 ± 6.7, P = 0.009). The increased percentage of BDNF was inversely correlated with the change in Zung SDS (r = -0.380, P = 0.022). Multivariate regression analysis showed that reduction in BDNF was independently associated with change in Zung SDS (95% confidence interval -0.315 to -0.052, P = 0.008). Zung SDS only significantly improved in men with increased fasting BDNF levels after a lifestyle intervention. (NCT01065753, ClinicalTrials.gov).

The stigma attached to mental disorders has been recognized as a major concern in healthcare services across societies. To compare the stigmatizing attitude towards patients with schizophrenia between the general public, relatives of patient with schizophrenia and relatives of patient with neurotic illnesses. The study sample of 600 subjects of Malay families was equally divided into three groups. The sample was selected using convenience sampling. Each subject completed a seven-item Social Distance Scale (SDS) and a six-item stereotypical beliefs (SB) scale of people with schizophrenia. Appropriate statistical analysis was then conducted to compare the differences in SDS and SB scores between the groups. The scores of both SD and SB were consistent with each other, which reflected that far social distance and more negative attitudes were strongly adopted by the general public. There were significant differences in the total and most of the individual item scores of the SDS and the SB between the general public and the two relatives groups. However, the difference in the SDS scores between the relatives of patient with schizophrenia and neurotic illnesses was not significant. Among the socio-demographic factors, educational status had a stronger influenced on stigma than age and sex. The stigma towards patients with schizophrenia among the Malay community was strong. Individuals who had been exposed to patient with schizophrenia or neurotic illnesses tended to have better perceptions towards schizophrenia than the general public. The contact that promotes familiarity with mental illness, which may diminish prejudicial attitudes, attributed to the improvement.

The object was to assess anxiety and depression during in vitro fertilisation (IVF) treatment and determine IVF-related psychological factors in infertile Chinese women. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate anxiety and depression among 842 patients, respectively. A univariate analysis was used to compare variables among three SAS groups and three SDS groups. Anxiety and depression were both represented in 21.3% of the cases. Patients <35 years tended to be more anxious. In women <35 years, the SDS scores were higher with lower educational backgrounds and female or couple's infertility, while the SAS scores were higher in female or couple's infertility. In older ones, the SDS scores were higher in those with lower educational backgrounds and longer time for infertility, while the SAS scores were higher in those with lower educational backgrounds. In SAS groups 1-3, the embryo availability was 5.0 (3.0-8.0), 5.0 (3.0-8.0), and 3.0 (2.0-4.5) (p = .013); and the fertilisation rate was 91.9, 90.4, and 81.8% (p < .001), respectively. We concluded that infertile women experience anxiety and depression during IVF treatment, especially in women <35 years. Younger women with female infertility would be more anxious and depressive while higher education can protect them from depression. In older ones, they would experience more depressive with longer time for infertility and be less anxious and depressive with higher education. Anxiety affects the fertilisation rate and embryo availability.

To explore the effects of five-element music therapy on elderly patients with seasonal affective disorder in a Chinese nursing home. The patients (n = 50) were recruited from a Shijingshan district nursing home in Beijing, China. They were randomly assigned to two groups, a treatment group and a control group, with 25 participants in each group. The patients received music therapy for 1-2 h each week over an 8-week period. The music therapy involved four phases: introduction, activities, listening to the Chinese five-element music, and a concluding phase. The participants in the control group did not listen to the five-element music. This study consisted of two parts: (a) a qualitative study that used focus groups to understand the feelings of the patients with seasonal affective disorder; (b) a quantitative study that involved administration of the self-rating depression scale (SDS) and Hamilton depression scale (HAMD) before and after treatment. (a) Qualitative analysis results: strength derived from the five-element group music therapy and emotional adjustment. The five-element group music therapy can reduce patients' psychological distress and let them feel inner peace and enhance their life satisfaction. (b) No significant difference in SDS and HAMD scores was found between the two groups (P > 0.05) prior to treatment. After treatment, the mean SDS score of the control group was 49.9 +/- 18.8, while the treatment group's score was 40.2 +/- 18.1. The HAMD score of the control group was 11.2 +/-3.1, and the treatment group's score was 8.8 +/- 4.9. Following 8 weeks of music therapy, the SDS and HAMD scores of the treatment group were significantly lower than those for the control group (P < 0.05). Five-element music therapy alleviated the symptoms of seasonal affective disorder in the elderly patients.

Eighty-four female cats undergoing ovariohysterectomy in a blinded, randomised, prospective clinical study were assigned to one of three groups of 28 to receive either 0.01 mg/kg buprenorphine (group B), 4 mg/kg carprofen (group C), or the same doses of both drugs (group BC). A dynamic and interactive visual analogue scale (DIVAS) from 0 to 100 mm, and a simple descriptive scale (SDS) from 0 to 4 were used to evaluate the cats' degree of analgesia and sedation for 24 hours postoperatively. There was no significant difference in the cats' sedation scores by SDS or DIVAS, and no difference in their pain scores by DIVAS. By SDS, the cats in group BC had significantly lower pain scores than the cats in group C (P<0.001) and group B (P<0.05). Nine of the cats in group B, nine in group C and five in group BC required rescue analgesia, and the cats in group C required rescue earlier than those in group B (P<0.05).

Folate deficiency is common in patients with epilepsy and also occurs in patients with depression or cognitive deficits. This study investigates whether low serum folate levels may contribute to depressive mood and difficulties in mental processing in patients with epilepsy treated with anti-epileptic drugs inducing the cytochrome P450. We analysed the serum folate levels, the score in the Self Rating Depression Scale (SDS) and the results of a bedside test in mental processing in 54 patients with epilepsy. There was a significant negative correlation between the serum folate levels and the score in SDS and significant positive correlations between the score in SDS and the time needed to process an interference task or a letter-reading task. Low serum folate levels may contribute to depressive mood and therefore to difficulties in mental processing. Further studies utilizing total plasma homocysteine as a sensitive measure of functional folate deficiency and more elaborate tests of mental processing are required to elucidate the impact of folate metabolism on depressive mood and cognitive function in patients with epilepsy.

The role of birth weight on growth hormone (GH) therapy response in GH-deficient (GHD) children has not been fully elucidated. Therefore, we examined the growth of 23 small-for-gestational-age GHD children (SGA-GHD, 11 females and 12 males), 26 appropriate-for-gestational-age GHD children (AGA-GHD, 11 females and 15 males) during the first 5 years of GH therapy and that of 22 non-GH-treated SGA children (12 females and 10 males). We collected height and height velocity measurements yearly. In AGA-GHD children, height was always greater than in the SGA groups and significantly increased from the fourth year of treatment. Height velocity was higher (SGA-GHD: 1.72 ± 0.30 standard deviation score, SDS, AGA-GHD: 2.67 ± 0.21 SDS; p = 0.039) in AGA-GHD children during the first year of treatment. The AGA-GHD group showed the highest percentage (52.4%) of subjects surpassing mid-parental height and the greatest height gain after 5 years of follow-up. Our results show that birth size is an important factor affecting the response to GH therapy in GHD children during the first 5 years of treatment. The paediatric endocrinologist should be aware of this factor when planning the management of GHD children born SGA. Copyright © 2013 S. Karger AG, Basel.

Although it is known that obesity predisposes to urolithiasis, a tendency for malnutrition in children with urolithiasis owing to recurrent urinary infections and abdominal pain also makes sense. In this study, we aimed to determine the nutritional status of infants and children with urolithiasis, and to observe whether obesity or malnutrition is more prevalent in that population. One hundred eighty-seven children aged 4 months to 17 years (mean, 4.9 ± 4.4 years) with urolithiasis, and 278 age- and sex-matched children without any chronic diseases were included. Anthropometric evaluations, including weight and height standard deviation score (SDS), body mass index, and triceps and subscapular skinfold thickness (SFT), were performed. Mean weight SDSs of the patients was statistically lower than that of the control subjects (P < .0001). Malnutrition rate was statistically higher in the patients with urolithiasis when evaluated according to weight SDS and percentiles of body mass index and SFT. When the age factor was taken into account, the percentage of malnutrition, determined by the percentiles of triceps and subscapular SFT measurements, was found to be higher in children younger than 2 years. Short stature was more prevalent in older children. Malnutrition among children with urolithiasis is not as rare as thought previously. A careful anthropometric evaluation should be included in the clinical assessment of those children. Copyright © 2013 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

To assess perceived motor competence, social competence, self-worth, health-related quality of life, and actual motor performancein 8-year-old survivors of neonatal extracorporeal membrane oxygenation (ECMO). In a prospective nationwide study, 135 children completed the extended version of the "athletic competence" domain of the Self Perception Profile for Children (SPPC) called the m-CBSK (Motor supplement of the Competentie BelevingsSchaal voor Kinderen) to assess perceived motor competence, the SPPC, and the Pediatric Quality of Life Inventory (PedsQL), andwere tested with the Movement Assessment Battery for Children. SD scores (SDS) were used to compare with the norm. The mean (SD) SDS for perceived motor competence, social competence, and self-worth were all significantly higher than the norm: 0.18 (0.94), P = .03; 0.35 (1.03), P < .001; and 0.32 (1.08), P < .001, respectively. The total PedsQL score was significantly below the norm: mean (SD) SDS: -1.26 (1.53), P < .001. Twenty-two percent of children had actual motor problems. The SDS m-CBSK and actual motor performance did not correlate (r = 0.12; P = .17). The SDS m-CBSK significantly correlated with the athletic competence domain of the SPPC (r = 0.63; P < .001). Eight-year-old ECMO survivors feel satisfied with their motor- and social competence, despite impaired PedsQL scores and motor problems. Because motor problems in ECMO survivorsdeteriorate throughout childhood, clinicians should be aware that these patients may tend to "overrate" their actual motor performance. Education andstrict monitoring of actual motor performanceare important to enable timelyintervention. Copyright © 2016 by the American Academy of Pediatrics.

We have previously reported on a case-series of children (n = 46) with suspected calcium-deficiency rickets who presented in The Gambia with rickets-like bone deformities. Biochemical analyses discounted vitamin D-deficiency as an aetiological factor but indicated a perturbation of Ca–P metabolism involving low plasma phosphate and high circulating fibroblast growth factor-23 (FGF23) concentrations. A follow-up study was conducted 5 years after presentation to investigate possible associated factors and characterise recovery. 35 children were investigated at follow-up (RFU). Clinical assessment of bone deformities, overnight fasted 2 h urine and blood samples, 2-day weighed dietary records and 24 h urine collections were obtained. Age- and season-matched data from children from the local community (LC) were used to calculate standard deviation scores (SDS) for RFU children. None of the RFU children had radiological signs of active rickets. However, over half had residual leg deformities consistent with rickets. Dietary Ca intake (SDS-Ca = − 0.52 (0.98) p = 0.04), dietary Ca/P ratio (SDS-Ca/P = − 0.80 (0.82) p = 0.0008) and TmP:GFR (SDS-TmP:GFR = − 0.48 (0.81) p = 0.04) were significantly lower in RFU children compared with LC children and circulating FGF23 concentration was elevated in 19% of RFU children. Furthermore an inverse relationship was seen between haemoglobin and FGF23 (R2 = 25.8, p = 0.004). This study has shown differences in biochemical and dietary profiles between Gambian children with a history of rickets-like bone deformities and children from the local community. This study provided evidence in support of the calcium deficiency hypothesis leading to urinary phosphate wasting and rickets and identified glomerular filtration rate and iron status as possible modulators of FGF23 metabolic pathways.

According to the COM-B ('Capability', 'Opportunity', 'Motivation' and 'Behaviour') model of behaviour, three factors are essential for behaviour to occur: capability, opportunity and motivation. Obese children are less likely to feel capable of exercising. The implementation of a new methodological approach to investigate the relationship between perceived exercise capability (PEC) and childhood obesity was conducted, which involved creating a new instrument, and demonstrating how it can be used to measure obesity intervention outcomes. A questionnaire aiming to measure perceived exercise capability, opportunity and motivation was systematically constructed using the COM-B model and administered to 71 obese children (aged 9-17 years (12.24±0.2.01), body mass index (BMI) standard deviation scores (SDS) 2.80±0.660) at a weight-management camp in northern England. Scale validity and reliability was assessed. Relationships between PEC, as measured by the questionnaire, and BMI SDS were investigated for the children at the weight-management camp, and for 45 Spanish schoolchildren (aged 9-13 years, (10.52±1.23), BMI SDS 0.80±0.99). A pilot study, demonstrating how the questionnaire can be used to measure the effectiveness of an intervention aiming to bring about improved PEC for weight-management camp attendees, was conducted. No participants withdrew from these studies. The questionnaire domain (exercise capability, opportunity and motivation) composite scales were found to have adequate internal consistency (a=0.712-0.796) and construct validity (χ(2)/degrees of freedom=1.55, root mean square error of approximation=0.072, comparative fit index=0.92). Linear regression revealed that low PEC was associated with higher baseline BMI SDS for both UK (b=-0.289, P=0.010) and Spanish (b=-0.446, P=0.047) participants. Pilot study findings provide preliminary evidence for PEC improvements through intervention being achievable, and measurable using the questionnaire. Evidence is presented for reliability and validity of the questionnaire, and for feasibility of its use in the context of a childhood obesity intervention. Future research could investigate the link between PEC and childhood obesity further.

Subjective memory complaints (SMC) and depressive symptoms (SDS) are common in the elderly population. However, the relationship among SMC, SDS, and cognitive function remains unclear. We investigated these associations in the elderly from cognitively normal (CN), pre-mild cognitive impairment (MCI), and amnestic MCI (aMCI) groups. Participants (CN, 299; pre-MCI, 106; aMCI, 267) underwent comprehensive clinical and neuropsychological assessment. and self-report SMC and SDS questionnaires. SMC and SDS were administered in a self-report format. For each neuropsychological test z-score, stepwise multiple linear regressions were performed to assess the relative contribution of SMC, SDS, and their interactions. SMC are associated with lower objective memory, while SDS are associated with lower psychomotor speed. Interactions between SMC and SDS were significant for tests of memory, executive function, psychomotor speed, and global cognition. Additional analyses revealed that SDS moderated the SMC-cognition relationship such that only individuals with higher SDS showed significant SMC-cognition associations. Due to the cross-sectional design, associations among SMC, SDS, and cognitive function was rather weak, albeit significant. Additionally, future biomarker studies, such as those assessing amyloid burden, are needed to explore the mechanisms underlying the relationship among SMC, SDS, and cognitive function. Early identification of individuals at risk for developing abnormal cognitive changes is critical. Our findings from the study involving a large sample of carefully selected participants suggest that SMC and SDS could be used as early detection markers of Alzheimer's disease. Copyright © 2017.

To assess possible delayed recovery of the maximum speech discrimination score (SDS) when the audiometric threshold ceases to change. We retrospectively examined 20 patients with idiopathic sudden sensorineural hearing loss (ISSNHL) (gender: 9 males and 11 females, age: 24-71 years). The findings of pure-tone average (PTA), maximum SDS, auditory brainstem responses (ABRs), and tinnitus handicap inventory (THI) were compared among the three periods of 1-3 months, 6-8 months, and 11-13 months after ISSNHL onset. No significant differences were noted in PTA, whereas an increase of greater than or equal to 10% in maximum SDS was recognized in 9 patients (45%) from the period of 1-3 months to the period of 11-13 months. Four of the 9 patients showed 20% or more recovery of maximum SDS. No significant differences were observed in the interpeak latency difference between waves I and V and the interaural latency difference of wave V in ABRs, whereas an improvement in the THI grade was recognized in 11 patients (55%) from the period of 1-3 months to the period of 11-13 months. The present study suggested the incidence of maximum SDS restoration over 1 year after ISSNHL onset. These findings may be because of the effects of auditory plasticity via the central auditory pathway. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

No study has investigated psychological dependence on antidepressants in patients with panic disorder, which was addressed in this study. This study was carried out in four psychiatric clinics in Tokyo, Japan. Individuals were eligible if they were outpatients aged 18 years or older and fulfilled the diagnostic criteria for panic disorder (ICD-10). Assessments included the Japanese Versions of the Severity of Dependence Scale (SDS), the Self-Report Version of Panic Disorder Severity Scale (PDSS-SR), and the Quick Inventory of Depressive Symptomatology-Self Report. Eighty-four individuals were included; of these, 30 patients (35.7%) showed psychological dependence on antidepressants (i.e. a total score of ≥5 in the SDS). A multiple regression analysis showed that PDSS scores and illness duration were correlated positively with SDS total scores. A binary regression model showed that absence of remission (i.e. a total score of ≥5 in the PDSS) and longer duration of illness increased the risk of dependence on antidepressants. Approximately one-third of the patients with panic disorder, receiving antidepressants, fulfilled the criteria for psychological dependence on these drugs. The results underscore the need for close monitoring, especially for those who present severe symptomatology or have a chronic course of the illness.

GH treatment significantly increased adult height (AH) in a dose-dependent manner in short non-GH-deficient children in a randomized, controlled, clinical trial; the mean gain in height SD score (heightSDS) was 1.3 (range 0-3), compared with 0.2 in the untreated group. The objective of the study was to analyze the relationship between IGF-1SDS, IGF binding protein-3 SDS (IGFBP3SDS), and their ratioSDS with a gain in the heightSDS until AH in non-GH-deficient short children. This was a randomized, controlled, multicenter clinical trial. The intervention included GH treatment: 33 or 67 μg/kg · d plus untreated controls. One hundred fifty-one non-GH-deficient short children were included in the intent-to-treat (ITT) population and 108 in the per-protocol (PP) population; 112 children in the ITT and 68 children in the PP populations had idiopathic short stature (ISS). Increments from baseline to on-treatment study mean IGF-1SDS (ΔIGF-1SDS), IGFBP3SDS, and IGF-1 to IGFBP3 ratioSDS were assessed in relationship to the gain in heightSDS. Sixty-two percent of the variance in the gain in heightSDS in children on GH treatment could be explained by four variables: ΔIGF-1SDS (explaining 28%), bone age delay, birth length (the taller the better), and GH dose (the higher the better). The lower IGF-1SDS was at baseline, the higher was its increment during treatment. For both the AllPP- and the ISSPP-treated groups, the attained IGF-1SDS study level did not correlate with height gain. In short non-GH-deficient children, the GH dose-related increment in IGF-1SDS from baseline to mean study level was the most important explanatory variable for long-term growth response from the peripubertal period until AH, when IGF-1SDS, IGFBP3SDS, and their ratioSDS were compared concurrently.

To establish an interference mode of group counseling for diabetic patients with depression and to evaluate the effectiveness of this mode on depression, treatment compliance and blood sugar level in the patients.
 One hundred diabetic patients with depression were randomly divided into a counseling group and a control group (n=50 per group). Self-Rating Depression Scale (SDS) was applied to all the patients. The interference mode of group counseling was established through literature review, expert consultation or interview. The counseling group received counseling for 8 times within 2 months.
 There was a significant difference in the SDS scores at 0, 3, 6 or 12 months after the intervention between the 2 groups (P<0.001). For the counseling group, there was a significant difference in the SDS scores between pre-intervention and 3, 6 or 12 months after intervention (P<0.001). However, there was no significant difference in the SDS scores between any two time points after the intervention (P>0.05). There was a significant difference in the compliance between any two time points after the intervention (P<0.05). Fasting blood glucose (FBG), 2 h postprandial blood glucose (2hPG) or glycosylated hemoglobin (HbA1c) was significantly different at any two time points after the intervention (P<0.05).
 Group counseling can improve depression, compliance and blood sugar control in the diabetic patients.

To evaluate the effects of levomilnacipran extended-release (LVM-ER; 40-120mg/day) on noradrenergic (NA) and anxiety-related symptoms in adults with major depressive disorder (MDD) and explore the relationship between these symptoms and functional impairment. Data were pooled from 5 randomized, double-blind, placebo-controlled trials (N=2598). Anxiety and NA Cluster scores were developed by adding selected item scores from the Montgomery-Åsberg Depression Rating Scale (MADRS) and 17-item Hamilton Depression Rating Scale (HAMD 17 ). A path analysis was conducted to estimate the direct effects of LVM-ER on functional impairment (Sheehan Disability Scale [SDS] total score) and the indirect effects through changes in NA and Anxiety Cluster scores. Mean improvements from baseline in NA and Anxiety Cluster scores were significantly greater with LVM-ER versus placebo (both P<0.001), as were the response rates (≥50% score improvement): NA Cluster (44% vs 34%; odds ratio=1.56; P<0.0001); Anxiety Cluster (39% vs 36%; odds ratio=1.19; P=0.041). Mean improvement in SDS total score was also significantly greater with LVM-ER versus placebo (-7.3 vs -5.6; P<0.0001). LVM-ER had an indirect effect on change in SDS total score that was mediated more strongly through NA Cluster score change (86%) than Anxiety Cluster score change (18%); the direct effect was negligible. NA and Anxiety Cluster scores, developed based on the face validity of individual MADRS and HAMD 17 items, were not predefined as efficacy outcomes in any of the studies. In adults with MDD, LVM-ER indirectly improved functional impairment mainly through improvements in NA symptoms and less so via anxiety symptoms. Copyright © 2016 The Authors.

The prevalence of depression has been reported to be higher in cancer patients, especially those of advanced stage, compared to normal controls. However, depression is often under-recognized in clinical oncology settings. And this psychological problem is not routinely assessed even in patients with inoperable metastatic cancer who often have psychological disorders. Psychological distress including depression, is affected by physical, psychosocial, and clinical factors. In order to detect psychiatric problems at the early stage, we assessed the mental conditions of 47 inpatients with metastatic gastric and colorectal cancerusing the Japanese version of Zung's Self Rating Depression Scale(SDS)and analyzed the relationships between these factors and SDS scores. While SDS scores of our patients did not differ according to their gender, age, performance status (PS), ortypes of patients' character, they were significantly higher in Group B(cancer patients with palliative care alone), compared to Group A(those receiving chemotherapy)(p<0. 001). As the disease in the four identical patients progressed to the terminal stage, their scores were significantly increased, respectively(p<0. 05). These results suggest that psychological intervention should be more critical for terminally ill patients without any indication of chemotherapy.

Introduction Obesity and metabolic syndrome (MetS) indicators have increased globally among the pediatric population. MetS indicators in the young elevate their risk of cardiovascular disease and metabolic disorders later in life. This study examined early onset obesity as a risk factor for MetS risk in adolescence. Methods A cohort of Chilean participants (N = 673) followed from infancy was assessed at age 5 years and in adolescence (mean age, 16.8 y). Adiposity was measured at both time points; blood pressure and fasting blood samples were assessed in adolescence only. Early onset obesity was defined as a World Health Organization z score of 2 standard deviations (SDs) or more for body mass index (BMI) at age 5 years. We used linear regression to examine the association between early onset obesity and adolescent MetS risk z score, adjusting for covariates. Results Eighteen percent of participants had early onset obesity, and 50% of these remained obese in adolescence. Mean MetS risk z score in adolescence was significantly higher among those with early onset obesity than among those without (1.0; SD, 0.8 vs 0.2; SD, 0.8 [P < .001]). In the multivariable model, early onset obesity independently contributed to a higher MetS risk score in adolescence (β = 0.27, P < .001), controlling for obesity status at adolescence and sex, and explained 39% of the variance in MetS risk. Conclusion Early onset obesity as young as age 5 years relates to higher MetS risk. PMID:29023232

To explore how growth measurements and attainment of developmental milestones in early childhood reflect the need for full-time special education (SE). After stratification in this population-based study, 900 pupils in full-time SE groups (age-range 7-16 years, mean 12 years 8 months) at three levels and 301 pupils in mainstream education (age-range 7-16, mean 12 years 9 months) provided data on height and weight from birth to age 7 years and head circumference to age 1 year. Developmental screening was evaluated from age 1 month to 48 months. Statistical methods included a general linear model (growth measurements), binary logistic regression analysis (odds ratios for growth), and multinomial logistic regression analysis (odds ratios for developmental milestones). At 1 year, a 1 standard deviation score (SDS) decrease in height raised the probability of SE placement by 40%, and a 1 SDS decrease in head size by 28%. In developmental screening, during the first months of life the gross motor milestones, especially head support, differentiated the children at levels 0-3. Thereafter, the fine motor milestones and those related to speech and social skills became more important. Children whose growth is mildly impaired, though in the normal range, and who fail to attain certain developmental milestones have an increased probability for SE and thus a need for special attention when toddlers age. Similar to the growth curves, these children seem to have consistent developmental curves (patterns).

While the main role of growth hormone (GH) replacement therapy in children is to promote linear growth, GH has also an effect on lipids and body composition. There is an ongoing discussion whether discontinuation of GH treatment is associated with deterioration of lipids. We analyzed weight status [as body mass index-standard deviation score (BMI-SDS)], insulin like growth factor (IGF)-1, triglycerides, total, low-density liporptoein (LDL)- and high-density lipoprotein (HDL)-cholesterol at the end of GH treatment and in mean 6 months later in 90 adolescents (53 with GH deficiency, 16 with Turner syndrome [TS] and 21 born small-for-gestational age [SGA]). After stopping GH treatment, total cholesterol (+10±24 mg/dL vs. -4±13 mg/dL) and LDL-cholesterol (+15±20 mg/dL vs. -6±12 mg/dL) increased significantly higher in severe (defined by GH peak in stimulation test <3 ng/mL) compared to moderate GHD. In patients with TS, total cholesterol (+19±9 mg/dL), LDL-cholesterol (+9±12 mg/dL) and HDL-cholesterol (+4.3±3.5 mg/dL) increased significantly. In adolescents born SGA, triglycerides increased (+34±51 mg/dL) and HDL-cholesterol decreased significantly (-3.8±7.1 mg/dL). In multiple linear regression analyses, changes of total and LDL-cholesterol were significantly negatively related to peak GH in stimulation tests, but not to gender, age at GH start, duration of GH treatment, observation time, changes of BMI-SDS or IGF-1 after the end of GH treatment. The BMI-SDS did not change after the end of GH treatment. Discontinuation of GH treatment leads to a deterioration of lipids in TS, SGA and severe but not moderate GHD.

Ectopic fat deposition in liver and skeletal muscle tissue is related to cardiovascular disease risk and is a common metabolic complication in obese children. We evaluated the hypotheses of ectopic fat in these organs could be diminished following 1 year of multidisciplinary care specialized in childhood obesity, and whether this reduction would associate with changes in other markers of metabolic function. This observational longitudinal study evaluated 40 overweight children and adolescents enrolled in a multidisciplinary treatment protocol at the Children's Obesity Clinic, Holbæk, Denmark. The participants were assessed by anthropometry, fasting blood samples (HbA1c, glucose, insulin, lipids, and biochemical variables of liver function), and liver and muscle fat content assessed by magnetic resonance spectroscopy at enrollment and following an average of 12.2 months of care. Univariate linear regression models adjusted for age, sex, treatment duration, baseline degree of obesity, and pubertal developmental stage were used for investigating possible associations. The standard deviation score (SDS) of baseline median body mass index (BMI) was 2.80 (range: 1.49-3.85) and the median age was 14 years (10-17). At the end of the observational period, the 40 children and adolescents (21 girls) significantly decreased their BMI SDS, liver fat, muscle fat, and visceral adipose tissue volume. The prevalence of hepatic steatosis changed from 28 to 20 % (p = 0.26) and the prevalence of muscular steatosis decreased from 75 to 45 % (p = 0.007). Changes in liver and muscle fat were independent of changes in BMI SDS, baseline degree of obesity, duration of treatment, age, sex, and pubertal developmental stage. A 1-year multidisciplinary intervention program in the setting of a childhood obesity outpatient clinic confers a biologically important reduction in liver and muscle fat; metabolic improvements that are independent of the magnitude of concurrent weight loss.

Excessive body weight, low physical activity and excessive sedentary time in youth are major public health concerns. A new generation of video games, the ones that require physical activity to play the games--i.e. active games--may be a promising alternative to traditional non-active games to promote physical activity and reduce sedentary behaviors in youth. The aim of this manuscript is to describe the design of a study evaluating the effects of a family oriented active game intervention, incorporating several motivational elements, on anthropometrics and health behaviors in adolescents. The study is a randomized controlled trial (RCT), with non-active gaming adolescents aged 12-16 years old randomly allocated to a ten month intervention (receiving active games, as well as an encouragement to play) or a waiting-list control group (receiving active games after the intervention period). Primary outcomes are adolescents' measured BMI-SDS (SDS=adjusted for mean standard deviation score), waist circumference-SDS, hip circumference and sum of skinfolds. Secondary outcomes are adolescents' self-reported time spent playing active and non-active games, other sedentary activities and consumption of sugar-sweetened beverages. In addition, a process evaluation is conducted, assessing the sustainability of the active games, enjoyment, perceived competence, perceived barriers for active game play, game context, injuries from active game play, activity replacement and intention to continue playing the active games. This is the first adequately powered RCT including normal weight adolescents, evaluating a reasonably long period of provision of and exposure to active games. Next, strong elements are the incorporating motivational elements for active game play and a comprehensive process evaluation. This trial will provide evidence regarding the potential contribution of active games in prevention of excessive weight gain in adolescents. Dutch Trial register NTR3228.

The present study analyses the gene expression profile of peripheral blood mononuclear cells (PBMC) from obese boys. The aims of the present study were to identify baseline differences between low responders (LR) and high responders (HR) after 10 weeks of a moderate energy-restricted dietary intervention, and to compare the gene expression profile between the baseline and the endpoint of the nutritional intervention. Spanish obese boys (age 10-14 years) were advised to follow a 10-week moderate energy-restricted diet. Participants were classified into two groups based on the association between the response to the nutritional intervention and the changes in BMI standard deviation score (BMI-SDS): HR group (n 6), who had a more decreased BMI-SDS; LR group (n 6), who either maintained or had an even increased BMI-SDS. The expression of 28,869 genes was analysed in PBMC from both groups at baseline and after the nutritional intervention, using the Affymetrix Human Gene 1.1 ST 24-Array plate microarray. At baseline, the HR group showed a lower expression of inflammation and immune response-related pathways, which suggests that the LR group could have a more developed pro-inflammatory phenotype. Concomitantly, LEPR and SIRPB1 genes were highly expressed in the LR group, indicating a tendency towards an impaired immune response and leptin resistance. Moreover, the moderate energy-restricted diet was able to down-regulate the inflammatory 'mitogen-activated protein kinase signalling pathway' in the HR group, as well as some inflammatory genes (AREG and TNFAIP3). The present study confirms that changes in the gene expression profile of PBMC in obese boys may help to understand the weight-loss response. However, further research is required to confirm these findings.

Growth retardation and its impact on adult height is considered to be one of the most common complications in patients with chronic kidney disease (CKD). Treatment with recombinant human growth hormone (rhGH) has been effective in improving growth in kidney transplantation (KTx) patients, but little data are available on adult height in patients who began rhGh treatment in late puberty. Near-adult height was evaluated in 13 KTx patients treated with rhGH [growth hormone group (GHGr); dose 9.33 mg/m 2 per week] for a period of at least 18 months. At initiation of rhGH treatment, testicular volume was >8 ml and serum testosterone was >1 ng/ml compared with the control group (CGr) of ten KTx patients who did not receive rHGH. All subjects were of similar chronological age and bone age and had similar creatinine clearance (CrCl) levels, cumulative corticoid dose, height standard deviation score (SDS), target height SDS, and target height:initial height at the beginning of the study. Near-adult height was significantly greater in the GHGr than in the CGr (-1.8 ± 0.8 vs. -2.9 ± 1.1; p = 0.018). The difference between initial height and near-adult height in the GHGr revealed a significant height gain (initial height -3.1 ± 1.1; near-adult height -1.8 ± 0.8 SDS, respectively; delta 1.2 ± 0.3; p = 0.021). The CrCl level was not significantly different between the GHGr and CGr at either at study initiation or when attaining near-adult height (p = 0.74 and p = 0.23, respectively). Treatment with rhGH was effective in improving adult height in KTx patients who began treatment in late puberty, without any effect on renal function.

Active video games as a tool to prevent excessive weight gain in adolescents: rationale, design and methods of a randomized controlled trial

PubMed Central

2014-01-01

Background Excessive body weight, low physical activity and excessive sedentary time in youth are major public health concerns. A new generation of video games, the ones that require physical activity to play the games –i.e. active games- may be a promising alternative to traditional non-active games to promote physical activity and reduce sedentary behaviors in youth. The aim of this manuscript is to describe the design of a study evaluating the effects of a family oriented active game intervention, incorporating several motivational elements, on anthropometrics and health behaviors in adolescents. Methods/Design The study is a randomized controlled trial (RCT), with non-active gaming adolescents aged 12 – 16 years old randomly allocated to a ten month intervention (receiving active games, as well as an encouragement to play) or a waiting-list control group (receiving active games after the intervention period). Primary outcomes are adolescents’ measured BMI-SDS (SDS = adjusted for mean standard deviation score), waist circumference-SDS, hip circumference and sum of skinfolds. Secondary outcomes are adolescents’ self-reported time spent playing active and non-active games, other sedentary activities and consumption of sugar-sweetened beverages. In addition, a process evaluation is conducted, assessing the sustainability of the active games, enjoyment, perceived competence, perceived barriers for active game play, game context, injuries from active game play, activity replacement and intention to continue playing the active games. Discussion This is the first adequately powered RCT including normal weight adolescents, evaluating a reasonably long period of provision of and exposure to active games. Next, strong elements are the incorporating motivational elements for active game play and a comprehensive process evaluation. This trial will provide evidence regarding the potential contribution of active games in prevention of excessive weight gain in adolescents. Trial registration Dutch Trial register NTR3228.

Context: Many children with idiopathic short stature have a delayed bone age. Idiopathic short stature with advanced bone age is far less common. Objective: The aim was to identify underlying genetic causes of short stature with advanced bone age. Setting and Design: We used whole-exome sequencing to study three families with autosomal-dominant short stature, advanced bone age, and premature growth cessation. Results: Affected individuals presented with short stature [adult heights −2.3 to −4.2 standard deviation scores (SDS)] with histories of early growth cessation or childhood short stature (height SDS −1.9 to −3.5 SDS), advancement of bone age, and normal endocrine evaluations. Whole-exome sequencing identified novel heterozygous variants in ACAN, which encodes aggrecan, a proteoglycan in the extracellular matrix of growth plate and other cartilaginous tissues. The variants were present in all affected, but in no unaffected, family members. In Family 1, a novel frameshift mutation in exon 3 (c.272delA) was identified, which is predicted to cause early truncation of the aggrecan protein. In Family 2, a base-pair substitution was found in a highly conserved location within a splice donor site (c.2026+1G>A), which is also likely to alter the amino acid sequence of a large portion of the protein. In Family 3, a missense variant (c.7064T>C) in exon 14 affects a highly conserved residue (L2355P) and is strongly predicted to perturb protein function. Conclusions: Our study demonstrates that heterozygous mutations in ACAN can cause a mild skeletal dysplasia, which presents clinically as short stature with advanced bone age. The accelerating effect on skeletal maturation has not previously been noted in the few prior reports of human ACAN mutations. Our findings thus expand the spectrum of ACAN defects and provide a new molecular genetic etiology for the unusual child who presents with short stature and accelerated skeletal maturation.

Diurnal dynamics of the standard deviation (SD) of three wind velocity components measured with a minisodar in the atmospheric boundary layer is analyzed. Statistical analysis of measurement data demonstrates that the SDs for x- and y-components σx and σy lie in the range from 0.2 to 4 m/s, and σz = 0.1-1.2 m/s. The increase of σx and σy with the altitude is described sufficiently well by a power law with exponent changing from 0.22 to 1.3 depending on time of day, and σz increases by a linear law. Approximation constants are determined and errors of their application are estimated. It is found that the maximal diurnal spread of SD values is 56% for σx and σy and 94% for σz. The established physical laws and the obtained approximation constants allow the diurnal dynamics of the SDs for three wind velocity components in the atmospheric boundary layer to be determined and can be recommended for application in models of the atmospheric boundary layer.

Arterial luminal diameters are routinely used to assess for vascular disease. Although small diameters are typically considered pathological, arterial dilatation has also been associated with disease. We hypothesize that extreme arterial diameters are biomarkers of the risk of vascular events. Participants in the Northern Manhattan Study who had a time-of-flight magnetic resonance angiography were included in this analysis (N=1034). A global arterial Z-score, called the brain arterial remodeling (BAR) score, was obtained by averaging the measured diameters within each individual. Individuals with a BAR score <-2 SDs were considered to have the smallest diameters, individuals with a BAR score >-2 and <2 SDs had average diameters, and individuals with a BAR score >2 SDs had the largest diameters. All vascular events were recorded prospectively after the brain magnetic resonance imaging. Spline curves and incidence rates were used to test our hypothesis. The association of the BAR score with death (P=0.001), vascular death (P=0.02), any vascular event (P=0.05), and myocardial infarction (P=0.10) was U-shaped except for ischemic stroke (P=0.74). Consequently, incidence rates for death, vascular death, myocardial infarction, and any vascular event were higher in individuals with the largest diameters, whereas individuals with the smallest diameters had a higher incidence of death, vascular death, any vascular event, and ischemic stroke compared with individuals with average diameters. The risk of death, vascular death, and any vascular event increased at both extremes of brain arterial diameters. The pathophysiology linking brain arterial remodeling to systemic vascular events needs further research. © 2015 The Authors.

To evaluate the effectiveness of hypnotic and musical relaxation therapy and psychological consultation for parents of children with cleft lip and/or palate (CLP) and to provide a scientific basis of clinical-psychological treatment options. Sixty-six subjects with children with CLP participated in this study. The subjects were randomly assigned to a test group (n = 33) and a control group (n = 33). The test group was treated with hypnotic and musical relaxation therapy; the control group were subjected to psychological consultation. Anxiety and depression states were evaluated by using a self-rating anxiety scale (SAS) and a self-rating depression scale (SDS) before and after treatment was administered. 1) The test group demonstrated a significant decrease in SAS and SDS scores (t = 2.855, P < 0.01; t = 2.777, P < 0.01). The control group showed a significant decrease in the SAS score (t = 1.831, P < 0.05) but failed to show a significant change in the depression score (t = 0.909, P > 0.05). 2) The test group yielded a higher percentage of remission indicated by the SDS scores than the control group (test group = 75.76%; control group = 60.61%; P < 0.05). The test group also displayed a higher percentage of remission indicated by the SAS scores than the control group (test group = 78.79%, test group = 69.70%; P < 0.05). Hypnotic and musical relaxation therapy can more effectively reduce the scores of the anxiety and depression states of the parents of patients with cleft lip and/or palate than psychological consultation.

The correction of Hawking temperature of Schwarzschild-de Sitter (SdS) black hole is investigated using the generalized Klein-Gordon equation and the generalized Dirac equation by taking the quantum gravity effects into account. We derive the corrected Hawking temperatures for scalar particles and fermions crossing the event horizon. The quantum gravity effects prevent the rise of temperature in the SdS black hole. Besides correction of Hawking temperature, the Hawking radiation of SdS black hole is also investigated using massive particles tunneling method. By considering self gravitation effect of the emitted particles and the space time background to be dynamical, it is also shown that the tunneling rate is related to the change of Bekenstein-Hawking entropy and small correction term (1 + 2 β m 2). If the energy and the angular momentum are taken to be conserved, the derived emission spectrum deviates from the pure thermal spectrum. This result gives a correction to the Hawking radiation and is also in agreement with the result of Parikh and Wilczek.

Multiplicative surrogate standard deviation: a group metric for the glycemic variability of individual hospitalized patients.

Group metrics are described to quantify blood glucose (BG) variability of hospitalized patients. The "multiplicative surrogate standard deviation" (MSSD) is the reverse-transformed group mean of the standard deviations (SDs) of the logarithmically transformed BG data set of each patient. The "geometric group mean" (GGM) is the reverse-transformed group mean of the means of the logarithmically transformed BG data set of each patient. Before reverse transformation is performed, the mean of means and mean of SDs each has its own SD, which becomes a multiplicative standard deviation (MSD) after reverse transformation. Statistical predictions and comparisons of parametric or nonparametric tests remain valid after reverse transformation. A subset of a previously published BG data set of 20 critically ill patients from the first 72 h of treatment under the SPRINT protocol was transformed logarithmically. After rank ordering according to the SD of the logarithmically transformed BG data of each patient, the cohort was divided into two equal groups, those having lower or higher variability. For the entire cohort, the GGM was 106 (÷/× 1.07) mg/dl, and MSSD was 1.24 (÷/× 1.07). For the subgroups having lower and higher variability, respectively, the GGM did not differ, 104 (÷/× 1.07) versus 109 (÷/× 1.07) mg/dl, but the MSSD differed, 1.17 (÷/× 1.03) versus 1.31 (÷/× 1.05), p = .00004. By using the MSSD with its MSD, groups can be characterized and compared according to glycemic variability of individual patient members. © 2013 Diabetes Technology Society.

Hypermobile Ehlers-Danlos syndrome (hEDS) is a common inherited connective tissue disorder characterized by joint hypermobility. The natural history of aortic root dilation (AoD), a potential complication of EDS, has not been well characterized in this population. We describe the natural history of aortic root size in a large cohort of patients with hEDS. A cohort of 325 patients with HEDS was identified at Cincinnati Children's Hospital Medical Center (CCHMC), including 163 patients from a previous study. Medical records were reviewed and each participant's height, weight, and aortic dimensions from up to four echocardiograms were documented. Aortic root z-scores were calculated using two established formulas based on age (Boston or Devereux). Overall prevalence of AoD and prevalence by age were calculated and longitudinal regression was performed. The prevalence of AoD with a z-score ≥ 2.0 was 14.2% (46/325) and with a z-score of ≥3.0 was 5.5% (18/325). No significant increases in z-score were seen over time for patients with multiple echocardiograms. Participants under the age of 15 years had an average decline of 0.1 standard deviations (SDs)/year. No significant change was found after 15 of age. Between the ages of 15 and 21 years, Boston z-scores were 0.96 higher than Devereux z-scores. The nearly 1 z-score unit difference between formulas indicates caution prior to diagnosing AoD in patients with hEDS. In light of the low prevalence and lack of progression of AoD, routine echocardiograms may not be warranted for pediatric patients with hEDS. © 2017 Wiley Periodicals, Inc.

Children with Prader-Willi syndrome (PWS) have abnormal body composition and impaired growth. Short-term GH treatment has beneficial effects. The aim of the study was to investigate effects of long-term continuous GH treatment on body composition, growth, bone maturation, and safety parameters. We conducted a multicenter prospective trial. Fifty-five children with a mean +/- sd age of 5.9 +/- 3.2 yr were followed during 4 yr of continuous GH treatment (1 mg/m(2) . d). Data were annually obtained in one center: fat percentage (fat%) and lean body mass (LBM) by dual-energy x-ray absorptiometry, height, weight, head circumference, bone age, blood pressure, and fasting IGF-I, IGF binding protein-3, glucose, insulin, glycosylated hemoglobin, total cholesterol, high-density lipoprotein, and low-density lipoprotein. sd scores (SDS) were calculated according to Dutch and PWS reference values (SDS and SDS(PWS)). Fat%SDS was significantly lower after 4 yr of GH treatment (P < 0.0001). LBMSDS significantly increased during the first year (P = 0.02) but returned to baseline values the second year and remained unchanged thereafter. Mean +/- sd height normalized from -2.27 +/- 1.2 SDS to -0.24 +/- 1.2 SDS (P < 0.0001). Head circumference SDS increased from -0.79 +/- 1.0 at start to 0.07 +/- 1.1 SDS after 4 yr. BMISDS(PWS) significantly decreased. Mean +/- sd IGF-I and the IGF-I/IGF binding protein-3 ratio significantly increased to 2.08 +/- 1.1 and 2.32 +/- 0.9 SDS, respectively. GH treatment had no adverse effects on bone maturation, blood pressure, glucose homeostasis, and serum lipids. Our study in children with PWS shows that 4 yr of continuous GH treatment (1 mg/m(2) . d) improves body composition by decreasing fat%SDS and stabilizing LBMSDS and head circumference SDS and normalizes heightSDS without adverse effects. Thus, long-term continuous GH treatment is an effective and safe therapy for children with PWS.

An a priori test of the difference engine model (Myerson, Hale, Zheng, Jenkins, & Widaman, 2003) was conducted using a large, diverse sample of individuals who performed three speeded verbal tasks and three speeded visuospatial tasks. Results demonstrated that, as predicted by the model, the group standard deviation (SD) on any task was proportional to the amount of processing required by that task. Both individual performances as well as those of fast and slow subgroups could be accurately predicted by the model using no free parameters, just an individual or subgroup's mean z-score and the values of theoretical constructs estimated from fits to the group SDs. Taken together, these results are consistent with post hoc analyses reported by Myerson et al. and provide even stronger supporting evidence. In particular, the ability to make quantitative predictions without using any free parameters provides the clearest demonstration to date of the power of an analytic approach on the basis of the difference engine.

Background Multiple clinical scoring systems have been proposed for Silver-Russell syndrome (SRS). Here we aimed to test a clinical scoring system for SRS and to analyse the correlation between (epi)genotype and phenotype. Subjects and methods Sixty-nine patients were examined by two physicians. Clinical scores were generated for all patients, with a new, six-item scoring system: (1) small for gestational age, birth length and/or weight ≤−2SDS, (2) postnatal growth retardation (height ≤−2SDS), (3) relative macrocephaly at birth, (4) body asymmetry, (5) feeding difficulties and/or body mass index (BMI) ≤−2SDS in toddlers; (6) protruding forehead at the age of 1–3 years. Subjects were considered to have likely SRS if they met at least four of these six criteria. Molecular investigations were performed blind to the clinical data. Results The 69 patients were classified into two groups (Likely-SRS (n=60), Unlikely-SRS (n=9)). Forty-six Likely-SRS patients (76.7%) displayed either 11p15 ICR1 hypomethylation (n=35; 58.3%) or maternal UPD of chromosome 7 (mUPD7) (n=11; 18.3%). Eight Unlikely-SRS patients had neither ICR1 hypomethylation nor mUPD7, whereas one patient had mUPD7. The clinical score and molecular results yielded four groups that differed significantly overall and for individual scoring system factors. Further molecular screening led identifying chromosomal abnormalities in Likely-SRS-double-negative and Unlikely-SRS groups. Four Likely-SRS-double negative patients carried a DLK1/GTL2 IG-DMR hypomethylation, a mUPD16; a mUPD20 and a de novo 1q21 microdeletion. Conclusions This new scoring system is very sensitive (98%) for the detection of patients with SRS with demonstrated molecular abnormalities. Given its clinical and molecular heterogeneity, SRS could be considered as a spectrum. PMID:25951829

We compared the results of 44 renal transplants in children, of whom 24 were treated with CSA/AZA and 20 with prednisone in combination with AZA and/or CSA. There were no differences in age distribution or mean ages at transplant between the two treatment groups. The CSA/AZA group had a longer follow-up (29 +/- 33 vs 17 +/- 18 months). At the last follow-up, five children in the CSA/AZA and none in the prednisone group had lost their grafts. Serum creatinine increased in both groups from 0.7 +/- 0.1 mg/dl and 0.9 +/- 0.1 mg/dl at the end of the first month to 1.1 +/- 0.2 mg/dl in the 36th month (CSA/AZA group) (P < 0.0001) and to 1.5 +/- 0.6 mg/dl in the 18th month (prednisone group) (P < 0.05), respectively. Total cholesterol level was 189 +/- 52 mg/dl and 178 +/- 60 mg/dl and LDL level was 117 +/- 48 mg/dl and 115 +/- 51 mg/dl for the prednisone and CSA/AZA groups, respectively. HDL was greater in the CSA/AZA group (50 +/- 10 vs 41 +/- 10 mg/dl) (P < 0.03), and VLDL was greater in the prednisone group (31 +/- 13 vs 22 +/- 8 mg/dl) (P < 0.05). Serum triglyceride was greater in the prednisone group (174 +/- 93 vs 112 +/- 50 mg/dl) (P < 0.03). The standard deviation score for height of the children in the prednisone group did not change (-2.4 +/- 1.4 vs -2.1 +/- 1.4 SDS), whereas the SDS height score for the CSA/AZA children increased from -3.1 +/- 1.7 to -2.6 +/- 1.5, -1.9 +/- 1.4 and -1.7 +/- 1.4, at 12, 24 and 36 months, respectively (P < 0.001). CSA/AZA is a good immunosuppressive regime for the first renal transplant in children, but only 75% tolerated AZA/CSA without same damage to their grafts.

We propose a new algorithm for calibrating definitive observatory data with the goal of providing users with estimates of the data error standard deviations (SDs). The algorithm has been implemented and tested using Chambon-la-Forêt observatory (CLF) data. The calibration process uses all available data. It is set as a large, weakly non-linear, inverse problem that ultimately provides estimates of baseline values in three orthogonal directions, together with their expected standard deviations. For this inverse problem, absolute data error statistics are estimated from two series of absolute measurements made within a day. Similarly, variometer data error statistics are derived by comparing variometer data time series between different pairs of instruments over few years. The comparisons of these time series led us to use an autoregressive process of order 1 (AR1 process) as a prior for the baselines. Therefore the obtained baselines do not vary smoothly in time. They have relatively small SDs, well below 300 pT when absolute data are recorded twice a week - i.e. within the daily to weekly measures recommended by INTERMAGNET. The algorithm was tested against the process traditionally used to derive baselines at CLF observatory, suggesting that statistics are less favourable when this latter process is used. Finally, two sets of definitive data were calibrated using the new algorithm. Their comparison shows that the definitive data SDs are less than 400 pT and may be slightly overestimated by our process: an indication that more work is required to have proper estimates of absolute data error statistics. For magnetic field modelling, the results show that even on isolated sites like CLF observatory, there are very localised signals over a large span of temporal frequencies that can be as large as 1 nT. The SDs reported here encompass signals of a few hundred metres and less than a day wavelengths.

The purpose of this study is to assess the relationship between magnetic resonance images (MRI) of the hypothalamic-pituitary (H-P) region and response to recombinant human growth hormone (rhGH) treatment in short children with growth hormone deficiency, basing on changes of auxologic parameters, as well as to answer the question if MRI may serve for selecting and monitoring the rhGH responders. The study group comprised 85 children treated with rhGH, aged 7.3-18.7 years, followed for the mean period of 3.2 years (range, 2.1-9.5 years). Auxologic parameters (height deficit hSDS, deviation from the mid-parental height hSDS-mpSDS, bone delay index bone age/chronological age ratio (BA/CA)) were assessed before, during and at the end of rhGH treatment; growth velocity was calculated before and during rhGH therapy. Parameters were correlated with the MRI of the H-P region. Structural anomalies of the H-P region were found in 22 (25.9%) children: empty sella syndrome (ESS) in 12 (14.1%) patients, ectopic posterior pituitary (EPP) in ten (11.8%). Patients' height deficit and their deviation from parental height before rhGH therapy was significantly greater in the EPP group (median hSDS = -3.8; hSDS-mpSDS = -2.5), bone age delay was the greatest in the ESS group (median BA/CA = 0.69), after therapy - in the EPP group (median BA/CA = 0.82). Growth velocity improved in the first year of the rhGH therapy in all groups; however, the most significant acceleration was observed in the EPP group (median delta hSDS = 0.9), then stabilised and was comparable in all groups. MRI may be helpful in predicting response to the rhGH treatment, providing midline abnormalities are taken into account.

In a questionnaire survey among 1329 first-trimester pregnant women, both the husband support measures and unwanted pregnancy ('stressor' agent in pregnancy) showed significant effects on an elevated score of the cognitive disturbance subscale of the Zung's self-rating depression scale (SDS), while only unwanted pregnancies showed an effect on an elevated score of the dysphoric mood subscale of the SDS. However, no interaction was observed between the husband support measures and unwanted pregnancy, therefore the effect of the husband's social support on the cognitive disturbance score was not that of a buffer, but rather a main effector. Finally, multiple regression analyses showed that the dysphoric mood score was preceded by unwanted pregnancy, premenstrual irritability, public self-consciousness, and maternal overprotection; while the cognitive disturbance score was preceded by unwanted pregnancy, husband reduced 'given' and 'giving' support, maternal reduced care and overprotection, paternal reduced care, low annual income, low private self-consciousness, and smoking. These findings suggest that the husband's support for a pregnant woman is effective only in reducing cognitive symptoms, and that different symptomatic constellations have different sets of psychosocial correlates.

Sjogren's syndrome dry eye (SSDE) mainly affects middle-aged women and can negatively affect women's psychological and social functioning. However, little is known about the correlation between vision-related quality of life (VR-QoL) and psychological status for women with SSDE. We therefore examined VR-QoL and psychological status in two groups of Chinese women: an SSDE group and a non-SSDE group. We also explored the associations between VR-QoL scores, sociodemographic measures, ophthalmologic parameters, and psychological status in women with SSDE. The case-control study recruited 30 female outpatients with SSDE and 30 without SSDE from the Eye and Ear, Nose, and Throat (ENT) Hospital of Fudan University. Demographic and ophthalmologic data were collected from all participants. Ophthalmologic examinations included best-corrected visual acuity (BCVA), corneal fluorescein staining (CFS), tear break-up time (TBUT) and Schirmer test. Data collected using the National Eye Institute's Visual Function Questionnaire (NEI-VFQ) and Ocular Surface Disease Index (OSDI) survey instruments were analyzed to identify potential differences in VR-QoL between the SSDE group and the non-SSDE group. We also used the Zung Self-Rating Anxiety and Self-Rating Depression Scales (SAS and SDS) to determine psychological status in both groups. The SSDE group scored significantly lower than the non-SSDE group on the NEI-VFQ subscales of general health, general vision, and long-distance vision activities (all p < 0.05). The SSDE group achieved a significantly higher ocular symptoms score compared with the control group (p = 0.0256). The SAS and SDS scores of the SSDE group were significantly higher than the non-SSDE group (p = 0.0072 and 0.0162, respectively). The prevalence of anxiety and depression in the SSDE group was significantly higher than the non-SSDE group (p = 0.0240 and 0.0200, respectively). Nine of twelve NEI-VFQ subscales were negatively correlated with SAS/SDS scores (all p values were <0.05). The exceptions were social function, color vision and peripheral vision. The composite OSDI score and its three subscale scores for the women in the SSDE group were all positively correlated with overall SAS/SDS scores (all p values were <0.05). Both VR-QoL and psychological status were significantly worse in SSDE group than in the non-SSDE group. The VR-QoL of women with SSDE had a negative correlation with their anxiety and depression levels.

This study compared the analgesic effects of epidural tramadol versus morphine in six healthy cats. Under general anesthesia, each cat received an epidural injection of saline 0.22 ml/kg (control treatment, CT), tramadol 1mg/kg (tramadol treatment, TT), or morphine 0.1mg/kg (morphine treatment, MT). After cats had recovered from anesthesia a simple descriptive scale (SDS), visual analog scale (VAS) and physiological parameters (respiratory and heart rate) were used to assess analgesia level to a noxious stimulus (base of the tail skin fold clamping) at 1, 2, 3, 4, 6, 8, 10, and 12h post-epidural. Group TT had a higher SDS and VAS score when compared to MT at 8, 10 and 12h post-epidural. CT had higher SDS and VAS score at all time points when compared to TT and MT. In conclusion both morphine and tramadol provided analgesia in this model for the first 6h; with epidural morphine resulting in longer lasting analgesia when compared to tramadol.

Psychosocial impairment represents an important treatment target in major depressive disorder (MDD). The majority of patients with MDD do not regain premorbid levels of psychosocial functioning despite the resolution of core depressive symptoms. This study aimed to investigate the respective effects of cognitive function and depression severity on impaired psychosocial function in MDD. Adults aged 18-65 with moderate-to-severe MDD (n = 100) and age-, sex-, and education-matched healthy controls participated in a cross-sectional study validating the THINC-integrated tool (THINC-it), a cognitive screening tool comprised of objective and subjective measures of cognitive function. Depression severity was assessed using the Montgomery-Åsberg Depression Rating Scale and psychosocial function was assessed using the Sheehan Disability Scale (SDS). Subjects with MDD reported greater impairment in psychosocial function than healthy controls, with significant differences in SDS total and domain scores (ps < .01) after controlling for age, sex, and education. Generalized linear models indicated that subjective cognitive function was most strongly associated with SDS total score (RR = .14, p = .01) and SDS domains of work/school (RR = .15, p = .03), family and home responsibilities (RR = .15, p = .02), and economic days lost (RR = .18, p =.03). Depression severity was most strongly associated with SDS social life (RR = .08, p < .01) and economic days underproductive (RR = .07, p < .01). Objective cognitive function was not significantly associated with any SDS outcomes. The cross-sectional, observational study design limits temporal inferences. The self-report nature of measures included may have influenced associations observed. Potential medication effects are not noted. Cognitive deficits, as measured by the THINC-it, are associated with significant psychosocial impairment in MDD. These results provide empirical support for the assessment of both subjective and objective measures of cognition, as they are not associated with each other and have differential effects on functional trajectory.

In cases of fungal infection of the bloodstream, rapid species identification is crucial to provide adapted therapy and thereby ameliorate patient outcome. Currently, the commercial Sepsityper kit and the sodium-dodecyl sulfate (SDS) method coupled with MALDI-TOF mass spectrometry are the most commonly reported lysis protocols for direct identification of fungi from positive blood culture vials. However, the performance of these two protocols has never been compared on clinical samples. Accordingly, we performed a two-step survey on two distinct panels of clinical positive blood culture vials to identify the most efficient protocol, establish an appropriate log score (LS) cut-off, and validate the best method. We first compared the performance of the Sepsityper and the SDS protocols on 71 clinical samples. For 69 monomicrobial samples, mass spectrometry LS values were significantly higher with the SDS protocol than with the Sepsityper method (P < .0001), especially when the best score of four deposited spots was considered. Next, we established the LS cut-off for accurate identification at 1.7, based on specimen DNA sequence data. Using this LS cut-off, 66 (95.6%) and 46 (66.6%) isolates were correctly identified at the species level with the SDS and the Sepsityper protocols, respectively. In the second arm of the survey, we validated the SDS protocol on an additional panel of 94 clinical samples. Ninety-two (98.9%) of 93 monomicrobial samples were correctly identified at the species level (median LS = 2.061). Overall, our data suggest that the SDS method yields more accurate species identification of yeasts, than the Sepsityper protocol. © The Author 2016.

Head circumference (HC) is a simple and practical measure of brain size, development and longitudinal measurements of the HC in childhood are an index of brain growth. To determine the effects of long IGF-I deficiency and treatment on HC in patients with Laron syndrome (LS). 20 untreated adult LS patients, aged 48.4±11.2 years and 13 LS patients treated between ages of 5.6±4 to 11.3±3 years were studied. 15 patients with congenital IGHD treated between age 6.1±4 and 13±4 by hGH served as controls. HC was expressed as standard deviation (SD) and Ht as SDS. HC was measured and plotted on Nellhaus charts. Linear height (Ht) was measured by a Harpenden Stadiometer. The mean HC deficit of the adult untreated LS males was -2.9±0.6 SD compared to a Ht deficit of -7.0±1.7 SDS. The HC of the LS adult females was -3.6±1 SD compared to a Ht SDS of -6.9±1.5 (p<0.001). IGF-I treatment (150-200 μg/kg once daily) increased the HC from -3.3±0.9 (m±SD) to normal values (0.87±1.8 SD) (p<0.001) in 11/13 children. The Ht SDS deficit decreased only by 1.5 SDS. hGH treatment of cIGHD children increased the HC from -2.0±1.8 to 0.3±1.2 SD and the Ht SDS from -4.8±1.6 to 1.6±1.0. Copyright © 2012 Elsevier Ltd.

Objectives In radiotherapy, delineation uncertainties are important as they contribute to systematic errors and can lead to geographical miss of the target. For margin computation, standard deviations (SDs) of all uncertainties must be included as SDs. The aim of this study was to quantify the interobserver delineation variation for stereotactic body radiotherapy (SBRT) of peripheral lung tumours using a cross-sectional study design. Methods 22 consecutive patients with 26 tumours were included. Positron emission tomography/CT scans were acquired for planning of SBRT. Three oncologists and three radiologists independently delineated the gross tumour volume. The interobserver variation was calculated as a mean of multiple SDs of distances to a reference contour, and calculated for the transversal plane (SDtrans) and craniocaudal (CC) direction (SDcc) separately. Concordance indexes and volume deviations were also calculated. Results Median tumour volume was 13.0 cm3, ranging from 0.3 to 60.4 cm3. The mean SDtrans was 0.15 cm (SD 0.08 cm) and the overall mean SDcc was 0.26 cm (SD 0.15 cm). Tumours with pleural contact had a significantly larger SDtrans than tumours surrounded by lung tissue. Conclusions The interobserver delineation variation was very small in this systematic cross-sectional analysis, although significantly larger in the CC direction than in the transversal plane, stressing that anisotropic margins should be applied. This study is the first to make a systematic cross-sectional analysis of delineation variation for peripheral lung tumours referred for SBRT, establishing the evidence that interobserver variation is very small for these tumours.

Outcome of children with intestinal failure (IF) has improved on treatment with parenteral nutrition (PN). The effects of PN and IF on body composition (BC) are unknown. The aim was to review BC in PN-treated children and those weaned off and to compare with reference data. Children on long-term/home PN underwent measurement of regional fat mass (FM) and lean mass (LM) using dual energy X-ray absorptiometry. Underlying diseases were intestinal enteropathy, n=15, short bowel syndrome (SBS), n=8 and intestinal dysmotility, n=11. PN duration was median 10 years. Fat Mass Index (FMI) and Lean Mass Index (LMI) were compared in children with and without intestinal inflammation, steroid treatment and according to PN dependency. 34 children aged 5-20 years were studied. They were short, mean height SD score (SDS) -1.8 (p<0.001) and light (mean weight SDS -0.86, p<0.001) with high body mass index (BMI) SDS: mean 0.4 (p=0.04) and low Limb LMI SDS -0.9 (p<0.001). Children with SBS had low FMI SDS -0.8 (p=0.01). BC did not significantly differ between diagnostic groups or with steroid treatment. Patients with intestinal inflammation (n=20) had higher BMI SDS than those without, p=0.007. Totally, PN-dependent children, n=11 had higher BMI SDS, p=0.004, total body FMI SDS, p=0.008 and trunk FMI SDS, p=0.001 compared with patients partially dependent and off PN. Significantly low limb LM was seen in all patient groups with high FM in children on total PN. Children with IF requiring PN treatment >27 days may benefit from BC monitoring and PN adjustment according to results in order to maximise linear growth and health in later life.

Sundown Ranch, a residential behavioral health care treatment facility for adolescents, tracked the progress and results of treatment by selecting performance measures from a psychosocial screening inventory. The temper scale was one of the two highest scales at admission and the highest scale at discharge. A clinical performance improvement (PI) project was conducted to assess improvements in clients' ability to manage anger after the incorporation of Rational Emotive Behavior Therapy (REBT) into treatment. Eighteen months of baseline data (July 1, 1999 - February 1, 2001) were collected, and 20 months of data (May 1, 2001 - December 31, 2002) were collected after the introduction of the PI activity. In all, data were collected for 541 consecutive admissions. A comparison of five successive quarterly reviews indicated average scores of 1.4 standard deviations (SDs) above the mean on the temper scale before the PI activity and .45 SD above the mean after. The performance threshold of reduction of the average temper scale score to < or =1 SD was met for 17 of 20 months. The fact that the PI activity reduced the temper scale elevations by almost one full SD is highly suggestive of the efficacy of REBT with the treatment population. After the project was completed, REBT was promoted as an additional therapeutic modality within the treatment program.

Malnutrition is a common problem in pediatric patients with cancer. Reported prevalence varies widely and has often been assessed only in a subset of childhood types of cancer. This study aimed to describe the prevalence of malnutrition among pediatric patients newly diagnosed with cancer, to describe the occurrence and course of malnutrition during therapy and to identify factors associated with malnutrition during therapy. In a retrospective cohort study of 327 patients diagnosed from 2003 to 2006 in three Swiss tertiary care hospitals, weight and height measures together with patient-, disease-, and treatment-related characteristics were assessed. Malnutrition was defined as body mass index (BMI) below -2 standard deviation scores (SDS) or a weight loss >10% from diagnosis. Malnutrition was assessed at diagnosis and continuously during anticancer therapy. At diagnosis, 5.8% of the patients (19) were malnourished based on BMI. During anticancer therapy, the cumulative incidence of malnutrition rose to 22% (70 patients) after 30 days, to 36% (116 patients) after 60 days, and finally to 47% (155 patients). In these 155 patients, the median duration of malnutrition was 60 days (interquartile range, 21-122). Age above 10 years at diagnosis, BMI ≤ -1.0 SDS at diagnosis, and a diagnosis of medulloblastoma were positively associated with a higher proportion of malnutrition time during therapy. The rapid increase of malnutrition after the start of treatment underlines the need to develop evidence-based and efficient methods to provide nutritional support for children with cancer.

Epigenetic mechanisms may be involved in obesity onset and its consequences. The aim of the present study was to evaluate whether DNA methylation status in microRNA (miRNA) coding regions is associated with childhood obesity. DNA isolated from white blood cells of 24 children (identification sample: 12 obese and 12 non-obese) from the Grupo Navarro de Obesidad Infantil study was hybridized in a 450 K methylation microarray. Several CpGs whose DNA methylation levels were statistically different between obese and non-obese were validated by MassArray® in 95 children (validation sample) from the same study. Microarray analysis identified 16 differentially methylated CpGs between both groups (6 hypermethylated and 10 hypomethylated). DNA methylation levels in miR-1203, miR-412 and miR-216A coding regions significantly correlated with body mass index standard deviation score (BMI-SDS) and explained up to 40% of the variation of BMI-SDS. The network analysis identified 19 well-defined obesity-relevant biological pathways from the KEGG database. MassArray® validation identified three regions located in or near miR-1203, miR-412 and miR-216A coding regions differentially methylated between obese and non-obese children. The current work identified three CpG sites located in coding regions of three miRNAs (miR-1203, miR-412 and miR-216A) that were differentially methylated between obese and non-obese children, suggesting a role of miRNA epigenetic regulation in childhood obesity. © 2016 World Obesity Federation.

Objective: The aim of this study was to evaluate the effects of using ACE inhibitors on insulin resistance, glucose metabolism, body fat composition, and lipid profile in children over 10 years of age with obesity-associated metabolic syndrome (MS). Methods: A total of 53 children with MS, who had been followed for at least one year were included in the study. The sample was divided into two groups: Group 1-30 obese children (13 female, 17 male) who were not using an ACE inhibitor and Group 2-23 obese children (13 female, 10 male) who were using an ACE inhibitor. Anthropometric and laboratory dataobtained at baseline and at the 3rd, 6th, and 12th months of follow-up were compared in the two groups. Results: Comparison of the data in the two groups at 3rd, 6th, and 12th months revealed no statistically significant differences in terms of weight standard deviation score (SDS), body mass index SDS, weight for height percentile, body fat percentage, and very low-density lipoprotein (VLDL)values. However, there were statistically significant differences in mean glucose and insulin levels, homeostasis model assessment for insulin resistance, LDL and high-density lipoprotein values, and highly significant differences in mean triglyceride values. Conclusions: The positive effects of ACE inhibitor drugs, particularly on hypertriglyceridemia and insulin resistance, might bring them forth as first-line drugs in the treatment of obese and hypertensive children. Randomized, controlled, double-blind, and long-term studies are needed for a definitive conclusion. Conflict of interest:None declared. PMID:24072084

To analyze cephalometric features in adults with isolated growth hormone (GH) deficiency (IGHD). Nine adult IGHD individuals (7 males and 2 females; mean age, 37.8 ± 13.8 years) underwent a cross-sectional cephalometric study, including 9 linear and 5 angular measurements. Posterior facial height/anterior facial height and lower-anterior facial height/anterior facial height ratios were calculated. To pool cephalometric measurements in both genders, results were normalized by standard deviation scores (SDS), using the population means from an atlas of the normal Brazilian population. All linear measurements were reduced in IGHD subjects. Total maxillary length was the most reduced parameter (-6.5 ± 1.7), followed by a cluster of six measurements: posterior cranial base length (-4.9 ± 1.1), total mandibular length (-4.4 ± 0.7), total posterior facial height (-4.4 ± 1.1), total anterior facial height (-4.3 ± 0.9), mandibular corpus length (-4.2 ± 0.8), and anterior cranial base length (-4.1 ± 1.7). Less affected measurements were lower-anterior facial height (-2.7 ± 0.7) and mandibular ramus height (-2.5 ± 1.5). SDS angular measurements were in the normal range, except for increased gonial angle (+2.5 ± 1.1). Posterior facial height/anterior facial height and lower-anterior facial height/anterior facial height ratios were not different from those of the reference group. Congenital, untreated IGHD causes reduction of all linear measurements of craniofacial growth, particularly total maxillary length. Angular measurements and facial height ratios are less affected, suggesting that lGHD causes proportional blunting of craniofacial growth.

X-linked acrogigantism (X-LAG) is a new syndrome of pituitary gigantism, caused by microduplications on chromosome Xq26.3, encompassing the gene GPR101, which is highly upregulated in pituitary tumors. We conducted this study to explore the clinical, radiological, and hormonal phenotype and responses to therapy in patients with X-LAG syndrome. The study included 18 patients (13 sporadic) with X-LAG and microduplication of chromosome Xq26.3. All sporadic cases had unique duplications and the inheritance pattern in two families was dominant, with all Xq26.3 duplication carriers being affected. Patients began to grow rapidly as early as 2-3 months of age (median 12 months). At diagnosis (median delay 27 months), patients had a median height and weight standard deviation scores (SDS) of >+3.9 SDS. Apart from the increased overall body size, the children had acromegalic symptoms including acral enlargement and facial coarsening. More than a third of cases had increased appetite. Patients had marked hypersecretion of GH/IGF1 and usually prolactin, due to a pituitary macroadenoma or hyperplasia. Primary neurosurgical control was achieved with extensive anterior pituitary resection, but postoperative hypopituitarism was frequent. Control with somatostatin analogs was not readily achieved despite moderate to high levels of expression of somatostatin receptor subtype-2 in tumor tissue. Postoperative use of adjuvant pegvisomant resulted in control of IGF1 in all five cases where it was employed. X-LAG is a new infant-onset gigantism syndrome that has a severe clinical phenotype leading to challenging disease management. © 2015 Society for Endocrinology.

Neuropsychological assessment aims to identify individual performance profiles in multiple domains of cognitive functioning; however, substantial variation exists in how deficits are defined and what cutoffs are used, and there is no universally accepted definition of neuropsychological impairment. The aim of this study was to derive and validate a clinical case definition rule to identify neuropsychological impairment in children and adolescents. An existing normative pediatric sample was used to calculate base rates of abnormal functioning on eight measures covering six domains of neuropsychological functioning. The dataset was analyzed by varying the range of cutoff levels [1, 1.5, and 2 standard deviations (SDs) below the mean] and number of indicators of impairment. The derived rule was evaluated by bootstrap, internal and external clinical validation (orthopedic and traumatic brain injury). Our neuropsychological impairment (NPI) rule was defined as "two or more test scores that fall 1.5 SDs below the mean." The rule identifies 5.1% of the total sample as impaired in the assessment battery and consistently targets between 3 and 7% of the population as impaired even when age, domains, and number of tests are varied. The NPI rate increases in groups known to exhibit cognitive deficits. The NPI rule provides a psychometrically derived method for interpreting performance across multiple tests and may be used in children 6-18 years. The rule may be useful to clinicians and scientists who wish to establish whether specific individuals or clinical populations present within expected norms versus impaired function across a battery of neuropsychological tests.

Almost 30% of adult patients with attention-deficit/hyperactivity disorder (ADHD) do not respond or tolerate standard pharmacological interventions. Few clinical investigations addressed the efficacy and tolerability of transcranial direct current stimulation (tDCS), a non-invasive neuromodulatory technique, in the disorder. We performed a double-blind, sham-controlled randomized clinical trial in 17 patients with ADHD. The set up for tDCS was the following: 2mA/20min/day for 5 days with the anode over the right dorsolateral prefrontal cortex and cathode over the left dorsolateral prefrontal cortex. ADHD symptoms were measured by the Adult ADHD Self-Report Scale (ASRS) and impairment with the Sheehan Disability Scale (SDS) in four different time points after stimulation. Participants achieved significant lower ASRS inattention and SDS scores after active tDCS in comparison with sham stimulation group. In addition, we detected a trend for a lower ASRS total score in the active tDCS group. Follow up data analysis revealed a positive interaction between time and treatment in both ASRS inattention, SDS and ASRS total scores. Short-term application of tDCS in adult patients with ADHD improved their symptoms, and this improvement persisted after the end of the stimulation. Future studies with larger sample sizes are needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The effect of time-of-flight (TOF) and point spread function (PSF) modeling in image reconstruction has not been well studied for cardiac PET. This study assesses their separate and combined influence on 82 Rb myocardial perfusion imaging in obese patients. Thirty-six obese patients underwent rest-stress 82 Rb cardiac PET. Images were reconstructed with and without TOF and PSF modeling. Perfusion was quantitatively compared using the AHA 17-segment model for patients grouped by BMI, cross-sectional body area in the scanner field of view, gender, and left ventricular myocardial volume. Summed rest scores (SRS), summed stress scores (SSS), and summed difference scores (SDS) were compared. TOF improved polar map visual uniformity and increased septal wall perfusion by up to 10%. This increase was greater for larger patients, more evident for patients grouped by cross-sectional area than by BMI, and more prominent for females. PSF modeling increased perfusion by about 1.5% in all cardiac segments. TOF modeling generally decreased SRS and SSS with significant decreases between 2.4 and 3.0 (P < .05), which could affect risk stratification; SDS remained about the same. With PSF modeling, SRS, SSS, and SDS were largely unchanged. TOF and PSF modeling affect regional and global perfusion, SRS, and SSS. Clinicians should consider these effects and gender-dependent differences when interpreting 82 Rb perfusion studies.

Introduction IGF-1 (insulin-like growth factor-1) is a hormone involved in cell growth and other important processes. In the kidney, IGF-1 has a stimulating effect, increasing the blood flow and glomerular filtration rate. Although many experimental animal studies regarding the role of IGF-1 in the kidney have been conducted, few human studies are available in the literature. Obesity is a cause of renal failure, and several glomerular lesions associated with obesity have been described. However, no studies regarding the levels of IGF-1 in morbidly obese patients with renal injury associated with obesity have been conducted. Aim To determine the serum IGF-1 concentrations in morbidly obese patients with normal renal function but with different types of early obesity-related glomerular lesions and to evaluate the possible relationship between IGF-1 and the presence of renal lesions. Methods Eighty morbidly obese patients with renal biopsy, including 11 patients with no evidence of renal lesion, 17 patients with single glomerulomegaly, 21 patients with single podocyte hypertrophy, 10 patients with glomerulomegaly and podocyte hypertrophy, 5 patients with focal segmental hyalinosis, and 16 patients with increased mesangial matrix and/or mesangial proliferation, participated in this study. Biological parameters, including serum IGF-1 concentrations with the standard deviation score for age (SDS-IGF-1), were determined for all patients. Results Eighty patients (50 women and 30 men) with a mean BMI of 52.63 ± 8.71 and a mean age of 42.40 ± 9.45 years were included in this study. IGF-1, IGF-1 SDS and IGF-1BP3 levels according to the renal injury were compared (normal glomeruli: IGF-1 = 190.17 ± 72.46; glomerulomegaly: IGF-1 = 122.3 ± 50.05; podocyte hypertrophy: IGF-1 = 119.81 ± 60.34; focal segmental hyalinosis: IGF-1 170.98 ± 100.83, increased mesangial matrix and/or mesangial proliferation: IGF-1 117.73 ± 63.87). Statistically significant differences were observed between serum levels of IGF-1 and between the levels of SDS-IGF-1 by comparing the group without glomerular lesion with the group formed by patients with any type of glomerular injury. Logistic regression analysis was performed, with the dependent variable defined as the glomerular injury. In the multivariate analysis, only SDS-IGF-1 was associated with glomerular injury, and low levels of IGF-1 SDS were a risk factor for kidney injury. Conclusions Our study demonstrates that low IGF-1 serum levels are associated with renal lesions in morbidly obese patients without overt clinical renal manifestations. PMID:27138941

Electrochemically driven emulsion inversion

Johans, Christoffer; Kontturi, Kyösti

2007-09-01

It is shown that emulsions stabilized by ionic surfactants can be inverted by controlling the electrical potential across the oil-water interface. The potential dependent partitioning of sodium dodecyl sulfate (SDS) was studied by cyclic voltammetry at the 1,2-dichlorobenzene|water interface. In the emulsion the potential control was achieved by using a potential-determining salt. The inversion of a 1,2-dichlorobenzene-in-water (O/W) emulsion stabilized by SDS was followed by conductometry as a function of added tetrapropylammonium chloride. A sudden drop in conductivity was observed, indicating the change of the continuous phase from water to 1,2-dichlorobenzene, i.e. a water-in-1,2-dichlorobenzene emulsion was formed. The inversion potential is well in accordance with that predicted by the hydrophilic-lipophilic deviation if the interfacial potential is appropriately accounted for.

The ability to generate patient-specific cells through induced pluripotent stem cell (iPSC) technology has encouraged development of three-dimensional extracellular matrix (ECM) scaffolds as bioactive substrates for cell differentiation with the long-range goal of bioengineering organs for transplantation. Perfusion decellularization uses the vasculature to remove resident cells, leaving an intact ECM template wherein new cells grow; however, a rigorous evaluative framework assessing ECM structural and biochemical quality is lacking. To address this, we developed histologic scoring systems to quantify fundamental characteristics of decellularized rodent kidneys: ECM structure (tubules, vessels, glomeruli) and cell removal. We also assessed growth factor retention--indicating matrix biofunctionality. These scoring systems evaluated three strategies developed to decellularize kidneys (1% Triton X-100, 1% Triton X-100/0.1% sodium dodecyl sulfate (SDS) and 0.02% Trypsin-0.05% EGTA/1% Triton X-100). Triton and Triton/SDS preserved renal microarchitecture and retained matrix-bound basic fibroblast growth factor and vascular endothelial growth factor. Trypsin caused structural deterioration and growth factor loss. Triton/SDS-decellularized scaffolds maintained 3 h of leak-free blood flow in a rodent transplantation model and supported repopulation with human iPSC-derived endothelial cells and tubular epithelial cells ex vivo. Taken together, we identify an optimal Triton/SDS-based decellularization strategy that produces a biomatrix that may ultimately serve as a rodent model for kidney bioengineering. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

Multiple clinical scoring systems have been proposed for Silver-Russell syndrome (SRS). Here we aimed to test a clinical scoring system for SRS and to analyse the correlation between (epi)genotype and phenotype. Sixty-nine patients were examined by two physicians. Clinical scores were generated for all patients, with a new, six-item scoring system: (1) small for gestational age, birth length and/or weight ≤-2SDS, (2) postnatal growth retardation (height ≤-2SDS), (3) relative macrocephaly at birth, (4) body asymmetry, (5) feeding difficulties and/or body mass index (BMI) ≤-2SDS in toddlers; (6) protruding forehead at the age of 1-3 years. Subjects were considered to have likely SRS if they met at least four of these six criteria. Molecular investigations were performed blind to the clinical data. The 69 patients were classified into two groups (Likely-SRS (n=60), Unlikely-SRS (n=9)). Forty-six Likely-SRS patients (76.7%) displayed either 11p15 ICR1 hypomethylation (n=35; 58.3%) or maternal UPD of chromosome 7 (mUPD7) (n=11; 18.3%). Eight Unlikely-SRS patients had neither ICR1 hypomethylation nor mUPD7, whereas one patient had mUPD7. The clinical score and molecular results yielded four groups that differed significantly overall and for individual scoring system factors. Further molecular screening led identifying chromosomal abnormalities in Likely-SRS-double-negative and Unlikely-SRS groups. Four Likely-SRS-double negative patients carried a DLK1/GTL2 IG-DMR hypomethylation, a mUPD16; a mUPD20 and a de novo 1q21 microdeletion. This new scoring system is very sensitive (98%) for the detection of patients with SRS with demonstrated molecular abnormalities. Given its clinical and molecular heterogeneity, SRS could be considered as a spectrum. Published by the BMJ Publishing Group Limited.

The aim of this study was to investigate the effects of hormone therapy (HT) on depression and depressive symptoms in prostate cancer patients undergoing 6 months of HT. One hundred two prostate cancer patients who had been prescribed HT completed the Zung Self-rating Depression Scale (SDS) and two questions about their sexual enjoyment and performance, plus a background questionnaire before HT, after 8 to 10 weeks of HT and again after 16 to 20 weeks of HT. There was a significant increase in SDS scores from before to during HT. High depression score before HT was a significant predictor of later increases in depression during HT. Increases in depressive symptoms were restricted to 8 of the 20 SDS symptoms, the most powerful change being in sexual anhedonia, which was a result of decreased ability to perform during sexual activity. The association between HT and elevated depression is confirmed, but the relative influence of sexual anhedonia over other depressive symptoms expands the understanding of this association. The effects of decreased ability to perform during sex appear to dominate the increase in depression during HT. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Use of dual-energy X-ray absorptiometry (DXA) for diagnosis and fracture risk assessment; WHO-criteria, T- and Z-score, and reference databases.

Dimai, Hans P

2017-11-01

Dual-energy X-ray absorptiometry (DXA) is a two-dimensional imaging technology developed to assess bone mineral density (BMD) of the entire human skeleton and also specifically of skeletal sites known to be most vulnerable to fracture. In order to simplify interpretation of BMD measurement results and allow comparability among different DXA-devices, the T-score concept was introduced. This concept involves an individual's BMD which is then compared with the mean value of a young healthy reference population, with the difference expressed as a standard deviation (SD). Since the early nineties of the past century, the diagnostic categories "normal, osteopenia, and osteoporosis", as recommended by a WHO working Group, are based on this concept. Thus, DXA is still the globally accepted "gold-standard" method for the noninvasive diagnosis of osteoporosis. Another score obtained from DXA measurement, termed Z-score, describes the number of SDs by which the BMD in an individual differs from the mean value expected for age and sex. Although not intended for diagnosis of osteoporosis in adults, it nevertheless provides information about an individual's fracture risk compared to peers. DXA measurement can either be used as a "stand-alone" means in the assessment of an individual's fracture risk, or incorporated into one of the available fracture risk assessment tools such as FRAX® or Garvan, thus improving the predictive power of such tools. The issue which reference databases should be used by DXA-device manufacturers for T-score reference standards has been recently addressed by an expert group, who recommended use National Health and Nutrition Examination Survey III (NHANES III) databases for the hip reference standard but own databases for the lumbar spine. Furthermore, in men it is recommended use female reference databases for calculation of the T-score and use male reference databases for calculation of Z-score. Copyright © 2017 Elsevier Inc.

Even if treated, acromegaly has a considerable impact on patient quality of life (QoL); despite this, the exact clinical determinants of QoL in acromegaly are unknown. This study retrospectively examines a cohort of treated patients with acromegaly, with the aim of identifying these determinants. Retrospective survey analysis, with 165 patients included in the study. All patients completed a survey, which included demographic data and the clinical details of their disease, the Short Form-36 Health Survey (SF-36), the revised Beck Depression Inventory (BDI-II), and the Bern Embitterment Inventory (BEI). Stepwise regression was used to identify predictors of QoL. The strongest predictors of the physical component score of the SF-36 were (in order of declining strength of association): Delay between first presentation of the disease and diagnosis, body mass index (BMI), number of doctors visited before the diagnosis of acromegaly, and age at diagnosis. For the mental component score, the strongest predictors were: number of doctors visited, previous radiotherapy, and age at study entry; and, for the BDI-II score: number of doctors visited, previous radiotherapy, age at study entry, and employment status at the time of diagnosis. The following were predictors of the BEI score: number of doctors visited, and age at study entry. Diagnostic delay and lack of diagnostic acumen in medical care provision are strong predictors of poor QoL in patients with acromegaly. Other identified parameters are radiotherapy, age, BMI, and employment status. An efficient acromegaly service should address these aspects when devising disease management plans.

Infants of women with pregestational diabetes are at risk for developing obesity in later life. This study aimed to identify subgroups at highest risk, by studying growth profiles of offspring from women with type 1 or 2 diabetes mellitus (ODM1, ODM2) until the age of 14 y. Information from infant welfare centers was received for 78 ODM1 and 44 ODM2. Mean BMI SD scores (SDS) (based on 1980 nation-wide references) and height SDS (based on 2009 references) were calculated and included in a random-effects model. Values were compared to the 2009 Dutch growth study. BMI SDS profiles differed between ODM1 and ODM2, with the highest mean BMI SDS profiles in ODM2. Other factors that affected growth profiles in these infants included the presence of maternal obesity, large for gestational age (LGA) at birth and in ODM2 a Dutch-Mediterranean origin. Offspring of women with diabetes have higher BMI SDS profiles than observed in the 2009 Dutch growth study, with the highest BMI SDS in ODM2 who are LGA at birth and have obese mothers. Preventive strategies for offspring adiposity may include pursuing lower prepregnancy maternal BMI, prevention of LGA at birth, and prevention of increased weight gain during childhood.

Typically, growth failure in Turner syndrome (TS) begins prenatally, and height sd score (SDS) declines progressively from birth. This study aimed to determine whether GH treatment initiated before 4 yr of age in girls with TS could prevent subsequent growth failure. Secondary objectives were to identify factors associated with treatment response, to determine whether outcome could be predicted by a regression model using these factors, and to assess the safety of GH treatment in this young cohort. This study was a prospective, randomized, controlled, open-label, multicenter clinical trial (Toddler Turner Study, August 1999 to August 2003). The study was conducted at 11 U.S. pediatric endocrine centers. Eighty-eight girls with TS, aged 9 months to 4 yr, were enrolled. Interventions comprised recombinant GH (50 mug/kg.d; n = 45) or no treatment (n = 43) for 2 yr. The main outcome measure was baseline-to-2-yr change in height SDS. Short stature was evident at baseline (mean length/height SDS = -1.6 +/- 1.0 at mean age 24.0 +/- 12.1 months). Mean height SDS increased in the GH group from -1.4 +/- 1.0 to -0.3 +/- 1.1 (1.1 SDS gain), whereas it decreased in the control group from -1.8 +/- 1.1 to -2.2 +/- 1.2 (0.5 SDS decline), resulting in a 2-yr between-group difference of 1.6 +/- 0.6 SDS (P < 0.0001). The baseline variable that correlated most strongly with 2-yr height gain was the difference between mid-parental height SDS and subjects' height SDS (r = 0.32; P = 0.04). Although attained height SDS at 2 yr could be predicted with good accuracy using baseline variables alone (R(2) = 0.81; P < 0.0001), prediction of 2-yr change in height SDS required inclusion of initial treatment response data (4-month or 1-yr height velocity) in the model (R(2) = 0.54; P < 0.0001). No new or unexpected safety signals associated with GH treatment were detected. Early GH treatment can correct growth failure and normalize height in infants and toddlers with TS.

The purpose of this study is to evaluate the association between blood pressure (BP) at 7-13 years of age and body mass index (BMI), early feeding, lifestyle indicators, and parental characteristics. Retrospective plus cross-sectional cohort study was started in 1294 children born in 2000-2004, right from their birth in primary care settings. Early feeding was estimated by measuring breast-feeding (BF) duration, complementary feeding (CF) introduction time, and lifestyle indicators such as daily screen time and weekly extracurricular sports activity time. Parental education, smoking, and obesity-related diseases were also considered. Multivariable linear regression and mediation analysis were used. CF introduction at 5-6 months of age was a negative predictor of systolic and diastolic BP (mean systolic BP-standard deviation score (SDS) -0.38 [95% CI: -0.47, -0.29] (p < 0.001); mean diastolic BP-SDS -0.32 [95% CI: -0.40, -0.24]) (p < 0.001); BMI was a positive predictor of systolic and diastolic BP (p < 0.001); and parental hypertension was a positive predictor of diastolic BP (p < 0.05). Predictors of mean BMI-SDS at 7-13 years of age were birth weight, screen time, and parental obesity and smoking (p < 0.001). BF had no effect on BP or BMI. Mediation analysis showed virtually no indication of the effect of CF on BP mediated by BMI. CF introduction between 5 and 6 months of age could be associated with low BP at 7-13 years. The effect of CF on BP seems to be independent of BMI. Low screen time is associated with low BMI. CF time may play a role in the occurrence of surrogates of noncommunicable disorders in future.

Obesity in children and adolescents is moving into the focus of public interest. Genetic as well as environmental factors are important in the etiology of obesity. The aim of this multicentre study was to correlate the weight of overweight or obese children and adolescents with that of their parents and siblings. Anthropometric and other data - comorbidities, various influencing factors and treatment - were collected from the adiposity data acquisition system for prospective surveillance (APS). Currently 125 medical centers and pediatric care clinics in Germany, Austria and Switzerland use the APS documentation. Until February 2008 data on a total of 37,062 children and adolescents had been collected. Data to calculate the Body Mass Index (BMI) were obtained from both parents of 11,074 (29,9%) children and adolescents. The mean BMI Standard Deviation Score (SDS) of these children and adolescents was 2.46. Their mean age was 11.9 years; 46% were males. The mean BMI-SDS of these children and adolescents correlated significantly with the BMI-SDS of both the mother (r=0.29 [Spearman's rank correlation coefficient]) and the father (r=018, both p<0.0001). The correlation with the father's BMI was closer in adolescents (15-20 years, r=0.20) than in young children (<10 years: r=0.12). The correlation with the mother's BMI was independent of age. A multivariate model including the BMI of the parents as well as age and sex of the children and adolescents explained 10.0% of the variance. Significant influencing factors were BMI of the mother, sex and the relationship between BMI of mother, age and sex. Data for the BMI of siblings were available of 3,933 (10.6 %) children and adolescents. The correlation of the BMI of the children and adolescents with that of their siblings was +0.17 (p<0.0001). This correlation was highest in adolescence (<10 years.: r=0.17, 15-20 years.: r=0.24, both p<0.0001). The patient's weight correlated more strongly with the mother's than the father's weight or that of the siblings.

Recombinant Growth hormone (rGH) therapy is approved in many countries for treatment of short stature in a number of childhood diagnoses. Despite the increasing body of international literature on rGH use, there is paucity of data on rGH use in Kuwait and the broader Middle-East which share unique ethnic and socio-cultural backgrounds. This study aimed to describe the pattern of use and treatment outcomes of rGH therapy in Kuwait. This is a cross-sectional retrospective review of children treated with rGH in the Department of Pediatrics, in a major hospital in Kuwait between December 2013 and December 2014. Data were extracted using standard data extraction form and the response to rGH therapy was defined as a gain of ≥ 0.3 standard deviation score (SDS) of height per year. A total of 60 children were treated with rGH in the center. Their Median (Interquartile) age at rGH initiation was 9.0 (6.2, 10.7) years. The most common indications for rGH therapy were Growth Hormone Deficiency (GHD) 23 (38.3 %), Idiopathic Short Stature (ISS) 12 (20.0 %) and Small for Gestational Age (SGA) 9 (15.0 %). After excluding patients with TS, no significant differences were found in gender of those who received rGH therapy in all indications combined or in each group (p ≥ 0.40). At 1-year follow-up, children in all groups had median height SDS change of ≥ 0.3 SDS except for children with ISS. Age at rGH initiation was negatively associated with 1-year treatment response, Adjusted odds ratio (AOR) 0.56 (95 % CI: 0.04-1.49); p = 0.011). GHD is the most common indication of rGH therapy. All indications except for ISS showed significant 1-year treatment response to therapy. Treatment outcomes in patients with ISS should be further investigated in Kuwait. Younger age at initiation of rGH therapy was independently associated with significant response to therapy suggesting the importance of identifying children with short stature and prompt initiation of rGH therapy.

Reversible ischaemia at radionuclide myocardial perfusion imaging (MPI) accurately predicts risk of cardiac death and nonfatal myocardial infarction (major adverse cardiac events, MACE). This prognostic penetrance might be empowered by accounting for exercise tolerance as an indirect index of ischaemia severity. The present study aimed to verify this hypothesis integrating imaging assessment of ischaemia severity with exercise maximal rate pressure product (RPP) in a large cohort of patients with suspected or known coronary artery disease (CAD). We analysed 1,502 consecutive patients (1,014 men aged 59 ± 10 years) submitted to exercise stress/rest MPI. To account for exercise tolerance, the summed difference score (SDS) was divided by RPP at tracer injection providing a clinical prognostic index (CPI). Reversible ischaemia was documented in 357 patients (24 %) and was classified by SDS as mild (SDS 2-4) in 180, moderate (SDS 5-7) in 118 and severe (SDS >7) in 59. CPI values of ischaemic patients were clustered into tertiles with lowest and highest values indicating low and high risk, respectively. CPI modified SDS risk prediction in 119/357 (33 %) patients. During a 60-month follow-up, MACE occurred in 68 patients. Kaplan-Meier analysis revealed that CPI significantly improved predictive power for MACE incidence with respect to SDS alone. Multivariate Cox analysis confirmed the additive independent value of CPI-derived information. Integration of ischaemic threshold and ischaemia extension and severity can improve accuracy of exercise MPI in predicting long-term outcome in a large cohort of patients with suspected or known CAD.

Aortic valve calcification (AVC) is recognized as a manifestation of systemic arteriosclerosis. However, it is unclear whether AVC is associated with myocardial ischemia. Stress myocardial perfusion SPECT (MPS) is widely used for the diagnosis of myocardial ischemia. However, routine MPS is not recommended, particularly in asymptomatic patients. Accordingly, we investigated the hypothesis that the presence of AVC is strongly associated with inducible myocardial ischemia, even among asymptomatic patients. We investigated 669 consecutive patients who underwent both adenosine stress (201)Tl MPS and echocardiography. We evaluated the extent and severity of myocardial ischemia by the summed difference score (SDS). We defined the presence of myocardial ischemia as SDS ≥ 3 and moderate to severe ischemia as SDS ≥ 8. We classified the severity of AVC according to the number of affected aortic leaflets. We also compared the mean SDS and the prevalence of SDS ≥ 3 and SDS ≥ 8 among patients stratified by the severity of AVC. The presence of AVC was significantly associated with myocardial ischemia (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.10-2.23; P = 0.013) and moderate to severe ischemia (OR, 2.16; 95% CI, 1.26-3.80; P = 0.0061). In 311 asymptomatic patients, AVC was strongly associated with moderate to severe ischemia (OR, 4.31; 95% CI, 1.67-12.8; P = 0.0043). However, the SDS value and the prevalence of SDS ≥ 3 and SDS ≥ 8 did not increase with increasing number of affected aortic leaflets. The presence of AVC may be associated with the presence of myocardial ischemia, particularly in asymptomatic patients. However, we found no association between the extent of AVC and inducible myocardial ischemia. The presence of AVC may be a useful anatomic marker to help identify patients at high risk of myocardial ischemia, particularly asymptomatic patients.

Long-term outcome after lifestyle interventions in obese children is largely unknown but important to improving intervention. The aim was to identify predictors of long-term changes in body mass index (BMI) after lifestyle intervention. Annual changes in the BMI SD score (BMI-SDS) over 5 y in 663 obese children (aged 4-16 y) motivated to participate in an outpatient lifestyle intervention were analyzed. Child-specific longitudinal curves based on multilevel growth curve models (MLMs) over 5 y were estimated depending on patient characteristics (age and sex). The mean decrease in BMI-SDS was 0.36 (95% CI: 0.33, 0.39) at the end of the 1-y intervention and 0.46 (95% CI: 0.36, 0.55) 4 y after the intervention. Change in BMI-SDS in the intervention period predicted long-term outcome after 5 y (P < 0.001). MLMs identified age but not sex as a predictor of the outcome: the youngest children (<8 y) at the onset of the intervention had the greatest decrease in BMI-SDS over 5 y, and the oldest children (>13 y) had the least decrease in BMI-SDS (P < 0.05). Whereas there was a larger reduction in BMI-SDS during the intervention in children aged 8-10 y than in children aged 11-12 y, long-term decrease in BMI-SDS was greater in 11-12-y-old children (P < 0.001). Younger age was associated with the best long-term outcome after participation in the lifestyle intervention, which supports the need for early intervention in childhood obesity. Children aged 8-10 y may need modified intervention, because BMI-SDS increased more in the older children in the long term. However, mean BMI-SDS was significantly lower 4 y after the end of the intervention than at baseline in all age groups. This study was registered at clinicaltrials.gov as NCT00435734.

To explore what percentage of suicide decedents (SDs) vs controls were assessed for suicidality at medical appointments in the year before death. Using the Rochester Epidemiology Project, 66 SDs dying in Olmsted County, Minnesota, between January 1, 2000, and December 31, 2009, were identified and matched with 141 age- and sex-matched controls. Blinded chart review determined how often providers screened and subjects endorsed suicidal ideation (SI). Positive indicators included chart notes recording SI and/or Patient Health Questionnaire-9 scored more than 0 on question 9. We found that only 29 of 66 (43.9%) SDs and 14 of 141 (9.9%) controls had been screened at any point by any means (P < .001). Only 25.8% (17 of 66) of SDs expressed SI, whereas 58.6% of screened SDs (17 of 29) did so, though none at final appointments before death. No control ever expressed SI. While the majority of both cases and controls went unscreened, providers were more likely to screen SDs (P < .001; odds ratio [OR], 9.0; 95% CI, 3.6-22.0), even with controlling for mental health diagnoses (P = .02; OR, 3.6; 95% CI, 1.2-10.6). With providers screening less than half of SDs at any point in the year before death, and less than 60% of SDs ever endorsing SI, including none at final appointments, the findings of this naturalistic study bring into question both current screening practices and screening effectiveness. Nonetheless, when SDs were screened, they were significantly more likely to endorse SI than were controls, not 1 of whom ever expressed SI. Taken together, these data suggest that patients expressing SI at any point are at elevated risk for eventual suicide. Copyright © 2018 Mayo Foundation for Medical Education and Research.

To study the effect of abdominal irradiation on spinal growth in childhood we have measured final height, sitting height, and leg length in 30 male survivors of a Wilms' tumor. Twenty-one patients received whole abdominal irradiation by either megavoltage therapy (MV: n = 11) or orthovoltage therapy (OV: n = 10); the remainder received flank irradiation. To examine the effect of the adolescent growth spurt on the irradiated spine we have followed prospectively seven patients who received whole abdominal irradiation and nine patients who received flank irradiation through puberty. Compared to a normal population there is a modest reduction inmore » median final standing height SDS (H.SDS: -1.15) accompanied by a marked reduction in median final sitting height SDS (S.HT SDS: -2.41) with no apparent effect on median subischial leg length SDS (SILL.SDS: 0.04). This reduction in spinal growth is reflected by a strongly positive disproportion score (DPS; (SILL SDS-S.HT SDS) + 2.81). The incidence of scoliosis after abdominal irradiation has been low (10%). During puberty there is a significant fall in median sitting height SDS after both whole abdominal (median fall: -0.9, P = 0.02) and flank irradiation (median fall: -1.85, P = 0.01), and this is reflected in a significant increase in disproportion (DPS: whole abdominal; median rise +1.4, P = 0.02: flank, median rise +1.34, P = 0.01). After MV irradiation there is a significant correlation between the degree of disproportion and the age at treatment (P less than 0.0005). The younger the patient is at treatment the more severe is the restriction on spinal growth and the shorter and more disproportionate they become as an adult. The estimated eventual loss in potential height from abdominal irradiation at the age of one is 10 cm and at five years is 7 cm.« less

BACKGROUND⁄ Pain-related misbeliefs among health care professionals (HCPs) are common and contribute to ineffective postoperative pain assessment. While standardized patients (SPs) have been effectively used to improve HCPs' assessment skills, not all centres have SP programs. The present equivalence randomized controlled pilot trial examined the efficacy of an alternative simulation method - deteriorating patient-based simulation (DPS) - versus SPs for improving HCPs' pain knowledge and assessment skills. Seventy-two HCPs were randomly assigned to a 3 h SP or DPS simulation intervention. Measures were recorded at baseline, immediate postintervention and two months postintervention. The primary outcome was HCPs' pain assessment performance as measured by the postoperative Pain Assessment Skills Tool (PAST). Secondary outcomes included HCPs knowledge of pain-related misbeliefs, and perceived satisfaction and quality of the simulation. These outcomes were measured by the Pain Beliefs Scale (PBS), the Satisfaction with Simulated Learning Scale (SSLS) and the Simulation Design Scale (SDS), respectively. Student's t tests were used to test for overall group differences in postintervention PAST, SSLS and SDS scores. One-way analysis of covariance tested for overall group differences in PBS scores. DPS and SP groups did not differ on post-test PAST, SSLS or SDS scores. Knowledge of pain-related misbeliefs was also similar between groups. These pilot data suggest that DPS is an effective simulation alternative for HCPs' education on postoperative pain assessment, with improvements in performance and knowledge comparable with SP-based simulation. An equivalence trial to examine the effectiveness of deteriorating patient-based simulation versus standardized patients is warranted.

To assess the efficacy, safety, and tolerability of brexpiprazole as adjunctive treatment in adults with major depressive disorder (MDD) and an inadequate response to prior antidepressant treatment (ADT). Patients with a current major depressive episode after prior treatment with 1-3 ADTs entered an 8- or 10-week prospective treatment phase in which they received double-blind placebo adjunct to open-label ADT. Inadequate responders were randomized (2:2:1) to brexpiprazole 2-3 mg/day, placebo, or quetiapine extended-release (XR) 150-300 mg/day, adjunct to the same ADT, for 6 weeks. The primary efficacy endpoint was the change from baseline (randomization) to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. The key secondary efficacy endpoint was the change in Sheehan Disability Scale (SDS) mean score. Adjunctive brexpiprazole showed a greater improvement in MADRS total score than adjunctive placebo (least squares mean difference [95% confidence interval] = -1.48 [-2.56, -0.39]; p = .0078), whereas adjunctive quetiapine XR did not separate from placebo (-0.30 [-1.63, 1.04]; p = .66). Adjunctive brexpiprazole failed to separate from placebo on the SDS mean score (-0.23 [-0.52, 0.07]; p = .13), but did improve functioning on two of the three SDS items (family life and social life). The most frequent treatment-emergent adverse events in patients receiving brexpiprazole were akathisia (6.1%), somnolence (5.6%), and headache (5.6%). Adjunctive brexpiprazole 2-3 mg/day improved symptoms of depression compared with adjunctive placebo in patients with MDD and an inadequate response to ADTs, and was well tolerated with no unexpected side effects.

The study assesses the association between religiosity and coping style with the outcome of depression and diabetes. Using a simple random sampling, we recruited 112 participants with diabetes and an equal number with depression consecutively, matching for gender. Religiosity was determined using Religious Orientation Scale (revised) (ROS-R), coping styles with Brief Religious Coping (Brief RCOPE) scale and Mental Adjustment to Cancer (MAC) scale (adapted). Primary and secondary outcomes were evaluated using Sheehan's Disability Scale (SDS) and Becks Depression Inventory-II (BDI-II) respectively. Among participants with diabetes, BDI-II total scores correlated negatively with ROS-R Extrinsic Social (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.3, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.3, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). SDS global scores correlated positively with Helplessness/Hopelessness (r = 0.3, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). Among participants with depression, BDI-II total scores correlated negatively with Intrinsic religiosity (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.4, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.6, P < 0.05) and Brief RCOPE Negative (r = 0.7, P < 0.05). SDS global scores correlated negatively with Intrinsic religiosity (r = -0.2, P < 0.05) and Fighting Spirit (r = -0.3, P < 0.05) but correlated positively with Helplessness/Hopelessness (r = 0.5, P < 0.05) and Brief RCOPE Negative (r = 0.4, P < 0.05). High intrinsic and extrinsic religiosities are likely to be associated with positive coping skills and better treatment outcome in patients with depression or diabetes. © 2015 John Wiley & Sons A/S.

Preterm birth has been associated with altered hypothalamic-pituitary-adrenal (HPA-) axis activity as well as cardiometabolic diseases and neurodevelopmental impairments later in life. We assessed cortisol from term age to age 8 y in children born preterm, to explore the development of HPA-axis activity in association with intrauterine and early-postnatal growth until 6 mo. corrected age. In 152 children born at a gestational age ≤32 wks. and/or with a birth weight ≤1,500g, random serum cortisol was assessed at term age (n=150), 3 mo. (n=145) and 6 mo. corrected age (n=144), and age 8 y (n=59). Salivary cortisol was assessed at age 8 y (n=75): prior to bedtime, at awakening, 15min after awakening, and before lunch. Cortisol was analyzed in association with birth weight-standard deviation score (SDS), being born small for gestational age (SGA), and combinations of intrauterine and postnatal growth: appropriate for gestational age (AGA) with or without growth restriction (AGA GR+ or AGA GR-) at 6 mo. corrected age, and SGA with or without catch-up growth (SGA CUG+ or SGA CUG-) at 6 mo. corrected age. Cross-sectional associations at all time points were analyzed using linear regression, and longitudinal associations were analyzed using generalized estimating equations. Longitudinally, birth weight-SDS was associated with cortisol (β [95%CI]): lower cortisol over time was seen in infants with a birth weight ≤-2 SDS (-50.69 [-94.27; -7.11], p=0.02), infants born SGA (-29.70 [-60.58; 1.19], p=0.06), AGA GR+ infants (-55.10 [-106.02; -4.17], p=0.03) and SGA CUG- infants (-61.91 [-104.73; -19.10], p=0.01). In cross-sectional analyses at age 8 y, no associations were found between either serum or salivary cortisol and birth weight-SDS, SGA-status, or growth from birth to 6 mo. corrected age. In children born preterm, poor intrauterine and postnatal growth were associated with lower cortisol in early infancy, but not at age 8 y. Even though HPA-axis activity no longer differed between groups at age 8 y, or differences could not be confirmed due to attrition, it is unknown whether the differences found in early infancy could attribute to increased health risks later in life.

Introduction Alström Syndrome (ALMS) is a rare autosomal recessive monogenic disease included in an emerging class of genetic disorders called ‘ciliopathies’ and is likely to impact the central nervous system as well as metabolic and endocrine function. Individuals with ALMS present clinical features resembling a growth hormone deficiency (GHD) condition, but thusfar no study has specifically investigated this aspect in a large population. Material and Methods Twenty-three ALMS patients (age 1-52 years, 11 M, 12 F) were evaluated for anthropometric parameters (growth charts and Standard Deviation Score (SDS) of height, weight, BMI), GH secretion by growth-hormone-releasing-hormone + arginine test (GHRH-arg), bone age, and hypothalamic-pituitary magnetic resonance imaging (MRI). A group of 17 healthy subjects served as controls in the GH secretion study. Longitudinal retrospective and prospective data were utilized. Results The length-for-age measurements from birth to 36 months showed normal growth with most values falling within -0,67 SDS to +1.28 SDS. A progressive decrease of stature-for-age was observed after 10 years of age, with a low final height in almost all ALMS subjects (> 16-20 years: mean SDS -2.22±1.16). The subset of 12 ALMS patients tested for GHRH-arg showed a significantly shorter stature than age-matched controls (154.7±10.6 cm vs 162.9±4.8 cm, p= 0.009), and a mild increase of BMI (Kg/m2) (27.8±4.8 vs 24.1±2.5, p=0.007). Peak GH after GHRH-arg was significantly lower in ALMS patients in comparison to controls (11.9±6.9 ug/L vs 86.1±33.2 ug/L, p <0,0001). Severe GHD was evident biochemically in 50% of ALMS patients. The 10 adult ALMS patients with GHD showed a reduced height in comparison to those without GHD (149.7±6.2 cm vs 161.9±9.2 cm, p= 0.04). MRIs of the diencephalic and pituitary regions were normal in 11 of 12 patients. Bone age was advanced in 43% of cases. Conclusions Our study shows that 50% of non-obese ALMS patients have an inadequate GH reserve to GHRH-arg and may be functionally GH deficient. The short stature reported in ALMS may be at least partially influenced by impairment of GH secretion. PMID:23445176

Accounting for body size deviations when reporting bone mineral density variables in children.

In a child, bone mineral density (BMD) may differ from an age-expected normal value, not only because of the presence of disease, but also because of deviations of height or weight from population averages. Appropriate adjustment for body size deviations simplifies interpretation of BMD measurements. For children, a bone mineral density (BMD) measurement is normally expressed as a Z score. Interpretation is complicated when weight or height distinctly differ from age-matched children. We develop a procedure to allow for the influence of body size deviations upon measured BMD. We examined the relation between body size deviation and spine, hip and whole body BMD deviation in 179 normal children (91 girls). Expressions were developed that allowed derivation of an expected BMD based on age, gender and body size deviation. The difference between measured and expected BMD was expressed as a HAW score (Height-, Age-, Weight-adjusted score). In a second independent sample of 26 normal children (14 girls), measured spine, total femur and whole body BMD all fell within the same single normal range after accounting for age, gender and body size deviations. When traditional Z scores and HAW scores were compared in 154 children, 17.5% showed differences of more than 1 unit and such differences were associated with height and weight deviations. For almost 1 in 5 children, body size deviations influence BMD to an extent that could alter clinical management.

Birth in periods with universal newborn screening (UNS) for permanent childhood hearing impairment (PCHI) and early confirmation of PCHI have been associated with superior subsequent language ability in children with PCHI. However their effects on reading and communication skills have not been addressed in a population-based study. In a follow-up study of a large birth cohort in southern England, we measured reading by direct assessment and communication skills by parent report in 120 children with bilateral moderate, severe or profound PCHI aged 5.4-11.7 years, of whom 61 had been born in periods with UNS, and in a comparison group of 63 children with normal hearing. Compared with birth during periods without UNS, birth during periods with UNS was associated with better reading scores (inter-group difference 0.39 SDs, 95% CI 0.02 to 0.76, p = 0.042) and communication skills scores (difference 0.51 SDs, 95% CI 0.06 to 0.95, p = 0.026). Compared with later confirmation, confirmation of PCHI by age 9 months was also associated with better reading (difference 0.51 SDs, 95% CI 0.15 to 0.87, p = 0.006) and communication skills (difference 0.56 SDs, 95% CI 0.12 to 1.00, p = 0.013). In the children with PCHI, reading, communication and language ability were highly correlated (r = 0.62-0.84, p<0.001). Birth during periods with UNS and early confirmation of PCHI predict better reading and communication abilities at primary school age. These benefits represent functional gains of sufficient magnitude to be important in children with PCHI.

This study aimed to assess attainment of genetic height potential after long-term growth hormone (GH) treatment in GH-naïve children diagnosed with isolated growth hormone deficiency (IGHD), multiple pituitary hormone deficiency (MPHD), born small for gestational age (SGA), or idiopathic short stature (ISS) enrolled in the American Norditropin® Web-enabled Research (ANSWER) Program. Children with IGHD (n=2884), MPHD (n=200), SGA (n=481), or ISS (n=733) with baseline height standard deviation score (HSDS)≤-2 were assessed over 5 years of GH treatment for mean HSDS, change in HSDS (ΔHSDS), and corrected HSDS (HSDS-target HSDS). Mean HSDS and corrected HSDS significantly increased to close to target height across all diagnostic groups after 5 years of GH treatment (P<0.0001). ∆HSDS at year 5 increased for all groups (IGHD: 1.8; MPHD: 2.1; SGA: 1.8; ISS: 1.6). Among patients who continued GH for 5 years, mean insulin-like growth factor-I (IGF-I) SDS increased to within normal range across all groups. Body mass index (BMI) SDS remained relatively stable in all diagnostic groups. Bone age (BA) increased, and the mean BA to chronological age (BA/CA) ratio reached or approached 1 across diagnostic groups over 5 years of GH treatment. Long-term GH therapy resulted in a significant increase in mean HSDS and corrected HSDS from baseline values in all diagnostic groups. The observed increase in mean corrected HSDS is consistent with growth that approached the patients' genetic height potential, although complete height gains will be evaluated at the attainment of final height.

Few studies have evaluated craniofacial growth in boys and girls with idiopathic short stature (ISS) during growth hormone (GH) treatment. The aim of this study was to evaluate the effect of GH treatment on craniofacial growth in children with ISS, compared with those with growth hormone deficiency (GHD). This study included 36 children (mean age, 11.3 ± 1.8 years) who were treated with GH consecutively. Lateral cephalograms were analyzed before and 2 years after start of GH treatment. There were no significant differences in age and sex between ISS and GHD groups and the reference group from semilongitudinal study (10 boys and 8 girls from each group). Before treatment, girls with ISS showed a skeletal Class II facial profile compared with the GHD and reference groups (p = 0.003). During GH treatment, the amount of maxillary length increased beyond norm in the ISS and GHD groups in boys (p = 0.035) > 3 standard deviation score (SDS). Meanwhile, mandibular ramus height (p = 0.001), corpus length, and total mandibular length (p = 0.007 for both) increased more in girls with ISS than in girls with GHD. Lower and total anterior facial heights increased more in girls with ISS than in girls with GHD (p = 0.021 and p = 0.007, respectively), > 7-11 SDS. GH should be administered carefully when treating girls with ISS, because GH treatment has great effects on vertical overgrowth of the mandible and can result in longer face. Copyright © 2016.

To investigate long-term effects on glycaemic control, ketoacidosis, serious hypoglycaemic events, insulin requirements, and body mass index standard deviation scores (BMI-SDS) in children and adolescents with type 1 diabetes starting on continuous subcutaneous insulin infusion (CSII) compared with children and adolescents treated with multiple daily injections (MDI). This retrospective case-control study compares 216 patients starting CSII with a control group on MDI (n = 215), matched for glycated hemoglobin (HbA1c), sex, and age during a 2-yr period. Variables collected were gender, age, HbA1c, insulin requirement, BMI, BMI-SDS, ketoacidosis, and serious hypoglycaemic events. In the CSII group there was an improvement in HbA1c after 6 and 12 months compared with the MDI group. For boys and girls separately the same effect was detected after 6 months, but only for boys after 12 months. The incidence of ketoacidosis was higher in the CSII group compared with the MDI group (2.8 vs. 0.5/100 person-yr). The incidences of severe hypoglycaemic episodes per 100 person-yr were three in the CSII group and six in the MDI group (p < 0.05). After 6, 12, and 24 months, the insulin requirement was higher in the MDI group. This study shows that treatment with CSII resulted in an improvement in HbA1c levels up to 1 yr and decreased the number of severe hypoglycaemic events, but the frequency of ketoacidosis increased. The major challenge is to identify methods to maintain the HbA1c improvement, especially among older children and teenagers, and reduce the frequency of ketoacidosis. © 2014 John Wiley & Sons A/S.

Children with Noonan syndrome show rapid decline of growth in the first year of life and feeding problems are present in over 50%. The aim of this study was to explore whether growth decelerates because of feeding problems or other Noonan syndrome-related factors. We performed a retrospective, longitudinal cohort study of clinically and genetically diagnosed subjects with Noonan syndrome (n = 143). Questionnaires about the phenotypic-genotypic profile and reported feeding problems were sent to eligible subjects. Data on first-year growth was obtained from growth charts. Ninety-one participants were excluded because of different criteria. A total of 52 subjects with Noonan syndrome were included. The largest decline in weight and length standard deviation score (SDS) occurred in the first 2.5 months after birth (-1.93 and -1.15, respectively), with feeding problems causing a decline of 0.57 SDS in the remaining months. At 1 year, children with feeding problems were on average 290 g lighter and 0.8 cm shorter than children without feeding problems. Weight gain was also negatively influenced by having a PTPN11 mutation (n = 39) and a higher gestational age, whereas children of parents with Noonan syndrome and with a higher birth weight gained more weight. Growth in length was reduced by having cardiac surgery and a higher gestational age, but positively influenced by birth length and maternal height. Growth in children with Noonan syndrome is impaired right after birth and only partially associated with feeding problems. In addition, several specific Noonan syndrome-related factors seem to influence growth in the first year. © 2018 Wiley Periodicals, Inc.

Growth hormone deficiency (GHD) results from variations affecting the production and release of growth hormone (GH) and is of 2 types: isolated growth hormone deficiency (IGHD) and combined pituitary hormone deficiency (CPHD). IGHD results from mutations in GH1 and GHRHR while CPHD is associated with defects in transcription factor genes PROP1 , POU1F1 , and HESX1. The present study reports on screening of POU1F1 , PROP1 , and HESX1 in CPHD patients and the novel variations identified. Fifty-one CPHD patients from 49 unrelated families clinically diagnosed on the basis of biochemical and imaging investigations along with 100 controls were enrolled. Detailed family history was noted from all participants and 5 ml blood samples drawn were processed for DNA isolation followed by direct sequencing of POU1F1 , PROP1 , and HESX1 genes. Of the 51 patients, 8 were females and 43 were males. Mean height standard deviation score (SDS) and weight SDS were -5.50 and -2.76, respectively. Thirty-six of the 51 patients underwent MRI of which 9 (25%) had normal pituitary structure and morphology while 27 (75%) showed abnormalities. Molecular analysis revealed 10 (20%) patients to have POU1F1 and PROP1 mutations/variations of which 5 were novel and 2 previously reported. No mutations were identified in HESX1. The novel variations identified were absent in the 100 healthy individuals screened and the control database Exome Aggregation Consortium (ExAC). Reported POU1F1 and PROP1 mutation hotspots were absent in our patients. Instead, novel POU1F1 changes were identified suggesting existence of a distinct mutation spectrum in our population. © Georg Thieme Verlag KG Stuttgart · New York.

Context: Heterozygous mutations in the aggrecan gene (ACAN) cause autosomal dominant short stature with accelerated skeletal maturation. Objective: We sought to characterize the phenotypic spectrum and response to growth-promoting therapies. Patients and Methods: One hundred three individuals (57 females, 46 males) from 20 families with autosomal dominant short stature and heterozygous ACAN mutations were identified and confirmed using whole-exome sequencing, targeted next-generation sequencing, and/or Sanger sequencing. Clinical information was collected from the medical records. Results: Identified ACAN variants showed perfect cosegregation with phenotype. Adult individuals had mildly disproportionate short stature [median height, −2.8 standard deviation score (SDS); range, −5.9 to −0.9] and a history of early growth cessation. The condition was frequently associated with early-onset osteoarthritis (12 families) and intervertebral disc disease (9 families). No apparent genotype–phenotype correlation was found between the type of ACAN mutation and the presence of joint complaints. Childhood height was less affected (median height, −2.0 SDS; range, −4.2 to −0.6). Most children with ACAN mutations had advanced bone age (bone age − chronologic age; median, +1.3 years; range, +0.0 to +3.7 years). Nineteen individuals had received growth hormone therapy with some evidence of increased growth velocity. Conclusions: Heterozygous ACAN mutations result in a phenotypic spectrum ranging from mild and proportionate short stature to a mild skeletal dysplasia with disproportionate short stature and brachydactyly. Many affected individuals developed early-onset osteoarthritis and degenerative disc disease, suggesting dysfunction of the articular cartilage and intervertebral disc cartilage. Additional studies are needed to determine the optimal treatment strategy for these patients. PMID:27870580

Medical nutritional therapy is important for glycemic control in children and adolescents with type 1 diabetes mellitus (T1DM). Carbohydrate (carb) counting, which is a more flexible nutritional method, has become popular in recent years. This study aimed to investigate the effects of carb counting on metabolic control, body measurements and serum lipid levels in children and adolescents with T1DM. T1DM patients aged 7-18 years and receiving flexible insulin therapy were divided into carb counting (n=52) and control (n=32) groups and were followed for 2 years in this randomized, controlled study. Demographic characteristics, body measurements, insulin requirements, hemoglobin A1c (HbA1c) and serum lipid levels at baseline and at follow-up were evaluated. There were no statistically significant differences between the groups in mean HbA1c values in the year preceding the study or in age, gender, duration of diabetes, puberty stage, total daily insulin dose, body mass index (BMI) standard deviation score (SDS) and serum lipid values. While there were no differences in BMI SDS, daily insulin requirement, total cholesterol, low-density lipoprotein and triglyceride values between the two groups (p>0.05) during the follow-up, annual mean HbA1c levels of the 2nd year were significantly lower in the carb counting group (p=0.010). The mean values of high-density lipoprotein were also significantly higher in the first and 2nd years in the carb counting group (p=0.02 and p=0.043, respectively). Carb counting may provide good metabolic control in children and adolescents with T1DM without causing any increase in weight or in insulin requirements.

Galectin-1, a recently identified peptide, is primarily released from the adipose tissue. Although galectin-1 was shown to have an anti-inflammatory effect, its specific function is not clearly understood. We aimed to evaluate the relationship of serum galectin-1 levels with clinical and laboratory parameters in childhood obesity. A total of 45 obese children (mean age: 12.1±3.1years) and 35 normal-weight children (mean age: 11.8±2.2years) were enrolled. Clinical [body mass index (BMI), waist circumference (WC), percentage of body fat and blood pressure] and biochemical [glucose, insulin, lipids, galectin-1, high-sensitive C-reactive protein (hsCRP) and leptin levels] parameters were assessed. Serum galectin-1, hsCRP and leptin levels were significantly higher in obese children than those in normal-weight children (12.4 vs 10.2ng/mL, p<0.001; 3.28 vs 0.63mg/L, p<0.001; 8.3 vs 1.2ng/mL, p<0.001, respectively). In obese children, galectin-1 levels correlated negatively with fasting glucose (r=-0.346, p=0.020) and positively with fat mass (r=0.326, p=0.026) and WC standard deviation score (SDS) (r=0.451, p=0.002). The multivariate regression analysis demonstrated that serum galectin-1 levels were significantly associated with fasting glucose and WC SDS. This study showed that obese children had significantly higher galectin-1 levels in proportion to fat mass in obese cases than those in healthy children, which may be interpreted as a compensatory increase in an attempt to improve glucose metabolism.

Overweight and obesity prevention in childhood and adolescence represent a priority for public health; school is a privileged place for health promotion interventions. The study aimed to test the effectiveness of a multicomponent 5-month intervention on the habits of primary school children, making the families aware of the importance of healthy choices. Two hundred nine children attending the fourth class of primary school, divided into interventional (n = 103) and control arm (n = 106) were included in the study. In the intervention group, parents and teachers received more intense lifestyle counseling, associated with weekly motivational telephone calls to families to motivate further their lifestyle changes. Standard deviation score (SDS) body mass index (BMI) was the primary outcome measure; on open-air games and TV watching were secondary outcomes. At baseline, no differences were observed between groups. At 8-month follow-up, mean SDS BMI had decreased by 0.06 units in the intervention arm and increased by 0.12 in controls (time × treatment anova, P < 0.002). Outdoor activities increased from 6.23 h week(-1) to 9.93 in the intervention group (P < 0.001), not in controls. This change was associated differences in TV watching from baseline (intervention, -0.96 h week(-1); P = 0.037; controls, +1.33 h week(-1); P = 0.031). A multicomponent school-based intervention addressing the needs of children, teachers and families produced a significant and favourable short-term effect on overweight/obese schoolchildren. © 2012 The Authors.

We assessed the relationship of fecal environmental contamination and environmental enteropathy. We compared markers of environmental enteropathy, parasite burden, and growth in 119 Bangladeshi children (≤ 48 months of age) across rural Bangladesh living in different levels of household environmental cleanliness defined by objective indicators of water quality and sanitary and hand-washing infrastructure. Adjusted for potential confounding characteristics, children from clean households had 0.54 SDs (95% confidence interval [CI] = 0.06, 1.01) higher height-for-age z scores (HAZs), 0.32 SDs (95% CI = −0.72, 0.08) lower lactulose:mannitol (L:M) ratios in urine, and 0.24 SDs (95% CI = −0.63, 0.16) lower immunoglobulin G endotoxin core antibody (IgG EndoCAb) titers than children from contaminated households. After adjusting for age and sex, a 1-unit increase in the ln L:M was associated with a 0.33 SDs decrease in HAZ (95% CI = −0.62, −0.05). These results are consistent with the hypothesis that environmental contamination causes growth faltering mediated through environmental enteropathy. PMID:23629931

Sleep disturbance symptom (SDS) is commonly reported in alcoholic patients. Polysomnography studies suggested that acamprosate decreased SDS. We assessed this hypothesis by using data of a randomized controlled trial. As a secondary objective, we suggested and tested the validity of a simple measurement of SDS based on the Hamilton depression and anxiety inventory subset. We re-analysed a multi-center study evaluating the efficacy of acamprosate compared with placebos on alcohol-dependent patients in concentrating on SDS change in time. The Sleep sum score index (SAEI) was built from check-lists on adverse effects reported at each visit and constituted our main endpoint. We also tested the validity of the short sleep index (SSI) defined by the four sleep items of the Hamilton depression and anxiety scales. Statistical analyses were conducted on an intention to treat basis. A total of 592 patients were included, and 292 completed the 6-month trial. Compared with SAEI considered as our reference, the observed specificity and sensitivity of SSI were 91.6 and 87.6%. From 40.2% of patients experiencing SDS at baseline, this proportion decreased until 26.1% at M6 in the placebo group and 19.5% in the acamprosate group (relative risk placebo/acamprosate = 1.49, 95% confidence interval 1.10, 1.98, P = 0.04). Treating alcoholic patients to enhance abstinence has a beneficial effect in reducing SDS, and the duration of abstinence during the treatment constitutes the main positive factor. An additional effect of acamprosate is conjectured from its effect on the glutamatergic tone. The SSI constitutes a simple, reasonably sensitive and specific instrument tool to measure SDS.

To evaluate auxology and metabolic disturbances in children with craniopharyngioma, and to present observational results of treatment of metabolic sequels with metformin and micronized fenofibrate. The studied group comprised 22 children [median age at diagnosis 10.5 (0.17-16.75) years; median follow-up 5.1 years]. Assessment included height standard deviations (SDS), body mass index (BMI) SDS, concentrations of lipids, glucose and insulin (fasting or oral glucose tolerance test) and homeostatic model assessment of insulin resistance (HOMA-IR) index. Ten adolescents with hyperinsulinemia and dyslipidemia received therapy with metformin (500-1500 mg/daily) and micronized fenofibrate (160 mg/daily). At diagnosis, median hSDS was -1.66 (range: -4.08; +0.1). Nine (40.9%) children were growth hormone-treated. There was gradual increase of BMI SDS, 18 (81.8%) patients being overweight at the final assessment. Dyslipidaemia was found in 19 patients (86.4%), hyperinsulinaemia in 11 patients (50%) and elevated HOMA-IR in 15 patients (68.2%). Decrease of triglycerides [median 263.5 (171-362) mg/dL vs. 154 (102-183) mg/dL] and HOMA-IR [8.64 (5.08-12.65) vs. 4.68 (0.7-7.9)] was significant in the group treated with metformin and fenofibrate for 6 months. Significant auxologic changes and metabolic abnormalities were found in children treated for craniopharyngioma. The use of metformin and fenofibrate seemed to attenuate these disturbances in a short-term observation.

Little is known about spontaneous growth of growth hormone (GH)-deficient children during infancy and childhood. Retrospectively, we calculated disease-specific pretreatment percentiles for height, weight, BMI and growth velocity of 113 GH-deficient boys and 41 GH-deficient girls from birth until 7 years of age, by mean and standard deviation. Infants with idiopathic GH deficiency (GHD) grow in disease-specific percentile channels. There is a significant difference in length and weight from birth onward compared to regional reference (p<0.001). Boys' birth length was 48.7+/-2.9 cm (p<0.001; -1.31+/-1.11 SDS), birth weight was 3.09+/-0.61 kg (p<0.01; -0.92+/-1.19 SDS), and BMI at birth was 12.9+/-1.7. Girls' birth length was 48.1+/-3.4 cm (p<0.05; -1.17+/-1.51 SDS), birth weight was 2.92+/-0.60 kg (p=0.05; -1.08+/-1.19 SDS), and BMI at birth was 12.6+/-2.2. There was a continuous loss of growth velocity, despite a wide variance in the first years, so height deficit became more evident with increasing age. GHD is a congenital disease no matter when height deficit becomes clinically evident, because GH-deficient children grow in disease-specific percentile channels with a highly significantly reduced length and weight, which demonstrates that GH is essential for adequate growth in infancy and early childhood.

Depressive tendency and nicotine dependency are factors related to the failure of smoking cessation. Women generally have a higher depressive tendency and difficulty in smoking cessation than men. However, the impact of sex differences on the relationship between nicotine dependency and depressive tendency remains unclear. We evaluated 727 patients (496 men and 231 women) who visited our outpatient clinic for smoking cessation therapy and compared various parameters measured between sexes during consultation. Age, duration of smoking, and daily cigarette consumption were significantly higher in men during the first visit. Women had significantly higher self-rating depression scale (SDS) scores and took significantly more antidepressant drugs than men. The SDS score significantly correlated with the Fagerström test for the nicotine dependence score and with daily cigarette consumption in women, but not in men. Thus, the present study demonstrates the differential relationship of depressive tendency with tobacco use or nicotine dependency in men and women, which might reflect sex differences in response to psychological stress.

2017-06-01

According to the temporal theory of autism spectrum disorders (ASDs), audiovisual changes in environment, particularly those linked to facial and verbal language, are often too fast to be faced, perceived, and/or interpreted online by many children with ASD, which could help explain their facial, verbal, and/or socioemotional interaction impairments. Our goal here was to test for the first time the impact of slowed-down audiovisual information on verbal cognition and behavior in 2 boys with ASD and verbal delay. Using 15 experimental sessions during 4 months, both boys were presented with various stimuli (eg, pictures, words, sentences, cartoons) and were then asked questions or given instructions regarding stimuli. The audiovisual stimuli and instructions/questions were presented on a computer's screen and were always displayed twice: at real-time speed (RTS) and at slowed-down speed (SDS) using the software Logiral. We scored the boys' verbal cognition performance (ie, ability to understand questions/instructions and answer them verbally/nonverbally) and their behavioral reactions (ie, attention, verbal/nonverbal communication, social reciprocity), and analyzed the effects of speed and order of the stimuli presentation on these factors. According to the results, both participants exhibited significant improvements in verbal cognition performance with SDS presentation compared with RTS presentation, and they scored better with RTS presentation when having SDS presentation before rather than after RTS presentation. Behavioral reactions were also improved in SDS conditions compared with RTS conditions. This initial evidence of a positive impact of slowed-down audiovisual information on verbal cognition should be tested in a large cohort of children with ASD and associated speech/language impairments.

Objective To examine the effect of α-lipoic acid on neuropathic symptoms in patients with diabetic neuropathy (DN). Methods Patients with painful DN were treated with 600 mg/day α-lipoic acid, orally, for 40 days. Neuropathy Symptom Score (NSS), Subjective Peripheral Neuropathy Screen Questionnaire (SPNSQ) and douleur neuropathique (DN)4 questionnaire scores were assessed at baseline and day 40. Quality-of-life treatment effects were assessed by Brief Pain Inventory (BPI), Neuropathic Pain Symptom Inventory (NPSI) and Sheehan Disability Scale (SDS). Changes in body weight, arterial blood pressure, fasting serum glucose and lipids were also assessed. Results Out of 72 patients included, significant reductions in neuropathic symptoms were shown by reduced NSS, SPNSQ and DN4 scores at day 40 versus baseline. BPI, NPSI, and SDS in terms of work disability, social life disability, and family life disability scores were also significantly reduced. Moreover, 50% of patients rated their health condition as 'very much better' or 'much better' following α-lipoic acid administration. Fasting triglyceride levels were reduced, but no difference was found in body weight, blood pressure, fasting glucose, or other lipids at day 40 versus baseline. Conclusions A-lipoic acid administration was associated with reduced neuropathic symptoms and triglycerides, and improved quality of life.

To provide quantitative conversions between commonly used scales for the assessment of negative symptoms in schizophrenia. Linear regression analyses generated conversion equations between symptom scores from the Scale for the Assessment of Negative Symptoms (SANS), the Schedule for the Deficit Syndrome (SDS), the Positive and Negative Syndrome Scale (PANSS), or the Negative Symptoms Assessment (NSA) based on a cross sectional sample of 176 individuals with schizophrenia. Intraclass correlations assessed the rating conversion accuracy based on a separate sub-sample of 29 patients who took part in the initial study as well as an independent sample of 28 additional subjects with schizophrenia. Between-scale negative symptom ratings were moderately to highly correlated (r = 0.73-0.91). Intraclass correlations between the original negative symptom rating scores and those obtained via using the conversion equations were in the range of 0.61-0.79. While there is a degree of non-overlap, several negative symptoms scores reflect measures of similar constructs and may be reliably converted between some scales. The conversion equations are provided at http://www.converteasy.org and may be used for meta- and mega-analyses that examine negative symptoms. Copyright © 2018 Elsevier B.V. All rights reserved.

Chronic neuro-musculoskeletal pain is an important complication of open-heart surgery (OHS). To better understand the development and natural course of neuro-musculoskeletal pain in the immediate post-OHS period, this prospective longitudinal study assessed the prevalence and degree of pain and shoulder disability, and areas of pain pre- and post-OHS. Usual medical, nursing, and physiotherapy care was provided including early extubation, education, walking, sitting out of bed, and upper, lower limb, and trunk exercises from day 1 post-operation. Of 114 elective patients who provided consent, 98 subjects were surveyed preoperatively, and at week 6 and week 12 post-OHS. Open and closed questions encompassed numerical rating of pain scales for various body areas summed as a total pain score (TPS), the shoulder disability score (SDS), exercise compliance, and sternal clicking. Usual care comprised mobility exercises, walking program, and cardiac rehabilitation referral. Survey return rates were 100%, 88%, and 82%, respectively. Of the 76 (78%) subjects with complete data sets, 68% subjects reported a history of previous neuro-musculoskeletal injuries/conditions preoperatively while prevalence for neuro-musculoskeletal pain was 64%, 88%, and 67% and 38%, 63%, and 42% for shoulder disability, at the three assessments. In all, 11% subjects reported sternal clicking at week 6 and 7% at week 12. Pain commonly occurred in the lower back and neck preoperatively, and in front of the chest, neck, rib cage, upper back, and left shoulder at week 6. Rib cage pain alone remained significantly greater than preoperative levels by week 12 post-OHS. Preoperative SDS was positively correlated with post-OHS length of stay; women had higher SDSs than men at week 6 and week 12 and week 12 SDS was negatively correlated with height. Surgical risk score was negatively correlated with change in SDS and TPS from pre-operation to week 12. In conclusion, neuro-musculoskeletal pain and shoulder disability were common preoperatively and while prevalence increased at week 6 post-OHS, overall preoperative levels were restored by week 12.

The aim of this study was to investigate left atrial (LA) function and synchrony in paroxysmal atrial fibrillation (PAF) patients using two-dimensional speckle tracking echocardiography (STE). Forty-five PAF patients and 30 healthy controls were enrolled. LA peak ventricular systolic longitudinal strain (LA S -S ) and strain rate (LA SR -S ) and left atrial longitudinal strain (LA S -A ) and strain rate (LA SR -A ) during late diastole were determined using STE, and the standard deviation of the time to peak (TPSD) of the regional strains was calculated to quantify LA dyssynchrony. TPSD during ventricular systole and late diastole were named SDs and SDa, respectively. Left atrial peak longitudinal strain during ventricular systole (LA S -S ) (29.34±8.57 vs 36.73±6.13), LA SR -S (1.27±0.311 vs 1.57±0.25), LA S -A (13.11±4.91 vs 17.86±3.57), and LA SR -A (-1.51±0.58 vs -1.90±0.30) were reduced in the PAF group compared with the controls (P<.05 for all). SDs (8.11±3.00% vs 4.67±1.48%) and SDa (5.57±2.26% vs 3.11±1.13%) were greater in PAF patients than in the controls (P<.05 for both). Furthermore, PAF patients with normal LA sizes exhibited lower LA S -S (P<.05), LA SR -S (P<.05), LA S -A (P<.05), and LA SR -A (P<.05) values and increased SDs (P<.05) and SDa (P<.05) values compared with the controls. Multivariate regression confirmed that SDs and SDa were powerful parameters for differentiating PAF patients from controls (SDs: sensitivity, 83%; specificity, 72%; SDa: sensitivity, 81%; specificity, 76%). Left atrial (LA) dysfunction and dyssynchrony in PAF patients can be detected with STE even in the absence of LA enlargement. STE-derived SDs and SDa were powerful parameters for identifying PAF patients. © 2017, Wiley Periodicals, Inc.

The impact of anxiety, seizure severity, executive dysfunction, subjectively perceived psychological deficits, and depression on social function in patients with epilepsy (PWE) was analyzed. A brief cognitive screening test (EpiTrack) and an estimation of the last 6 months' cumulative seizure severity (Chalfont seizure severity scale) were performed, and questionnaires on subjectively perceived cognitive deficits (c.I.-Skala), anxiety (State-Trait Anxiety Inventory, STAIX1 and STAIX2), depression (Self Rating Depression Scale, SDS), and social function (Soziale Aktivität Selbstbeurteilungsskala, SASS) were completed. Forty PWE (aged 41.8 years, SD 16; 24 female, 16 male) were analyzed. Thirty-eight point 5 percent had a score signifying depression in the SDS; 20% had a pathological result in at least one of the anxiety scores. The ANOVA revealed that only anxiety as a trait symptom (STAIX2) had a significant influence on social function apart from the other factors (p<0.004). Additionally there was a trend for a significant influence of depressive symptoms (SDS) on social functioning (p=0.093). Symptoms of anxiety impair the social function of patients with epilepsy apart from depression, cognitive function, and seizure severity. They should be taken into account in the treatment of patients with epilepsy. Copyright © 2015 Elsevier Inc. All rights reserved.

Seasonal severity of depressive symptoms as a predictor of health service use in a community-based sample.

Vigod, Simone N; Levitt, Anthony J

2011-05-01

To determine whether severity of seasonal depressive symptoms is an independent predictor of depression-specific health service use. Cross-sectional telephone survey evaluating mood-related symptom changes across seasons using a structured interview based on the World Mental Health Composite International Diagnostic Interview, in a community sample representative of the province of Ontario, Canada (N = 1605). This study focuses on the 625 individuals (out of a total of 1605 interviewed) who screened positive for lifetime depressive symptoms. Severity of seasonal symptoms of depression (or "seasonality") was measured using the Seasonal Depression Severity (SDS) score (range 0-36). The primary outcome was lifetime depression-specific use of health services from a physician (family physician or psychiatrist). Lifetime psychotropic medication use, use of health services from a non-physician therapist, and psychiatric hospitalization were secondary outcomes. Other important variables that are known to predict depression-specific health service use were considered in multivariable analysis. In our sample of individuals with depressive symptoms, those who had used physician health services had higher SDS scores than non-users (11.5 (SD 7.2) vs. 9.7 (SD 6.4), t(616) = 3.182, P = 0.001). In multivariable analysis, SDS score was independently associated with depression-specific health service use by a physician (OR = 1.04, 95% CI 1.01-1.07, p = 0.004). The relationship between seasonality and use of psychotropic medication use was similar (OR = 1.04, 95% CI 1.01-1.07, p = 0.007). Seasonality was independently associated with depression-specific health service use for individuals with depressive symptoms. The results imply that greater seasonality may independently reflect increased severity and need for treatment of depression. Copyright © 2010 Elsevier Ltd. All rights reserved.

Transsexual patients' psychiatric comorbidity and positive effect of cross-sex hormonal treatment on mental health: results from a longitudinal study.

Colizzi, Marco; Costa, Rosalia; Todarello, Orlando

2014-01-01

The aim of the present study was to evaluate the presence of psychiatric diseases/symptoms in transsexual patients and to compare psychiatric distress related to the hormonal intervention in a one year follow-up assessment. We investigated 118 patients before starting the hormonal therapy and after about 12 months. We used the SCID-I to determine major mental disorders and functional impairment. We used the Zung Self-Rating Anxiety Scale (SAS) and the Zung Self-Rating Depression Scale (SDS) for evaluating self-reported anxiety and depression. We used the Symptom Checklist 90-R (SCL-90-R) for assessing self-reported global psychological symptoms. Seventeen patients (14%) had a DSM-IV-TR axis I psychiatric comorbidity. At enrollment the mean SAS score was above the normal range. The mean SDS and SCL-90-R scores were on the normal range except for SCL-90-R anxiety subscale. When treated, patients reported lower SAS, SDS and SCL-90-R scores, with statistically significant differences. Psychiatric distress and functional impairment were present in a significantly higher percentage of patients before starting the hormonal treatment than after 12 months (50% vs. 17% for anxiety; 42% vs. 23% for depression; 24% vs. 11% for psychological symptoms; 23% vs. 10% for functional impairment). The results revealed that the majority of transsexual patients have no psychiatric comorbidity, suggesting that transsexualism is not necessarily associated with severe comorbid psychiatric findings. The condition, however, seemed to be associated with subthreshold anxiety/depression, psychological symptoms and functional impairment. Moreover, treated patients reported less psychiatric distress. Therefore, hormonal treatment seemed to have a positive effect on transsexual patients' mental health. Copyright © 2013 Elsevier Ltd. All rights reserved.

Objective In adults, improper arterial function has been linked to cognitive impairment. The pulse wave velocity (PWV), augmentation index (AIx) and other vascular parameters are useful indicators of arterial health. In our study, we monitored arterial properties, body constitution, school success, and motor skills in young adolescents. We hypothesize that reduced cognitive and motor abilities have a vascular origin in children. Methods We analysed 81 healthy school children aged 11-16 years. Anthropometry central systolic arterial pressure, body mass index (BMI), standard deviation scores (SDS) BMI, general school performance grade, and eight motor tests were assessed. PWV, AIx, and central systolic arterial pressure (SBPao) were measured. Results AIx and SBPao correlated negatively with school performance grades. Extremely high AIx, PWV and SBPao values were observed in 5% of children and these children had average to low school performance. PWV correlated significantly with weight, height, and waist and hip circumference. AIx, PWV, school success, and BMI correlated strongly with certain motor functions. Conclusions Increased AIx and SBPao are associated with lower school and motor performance in children. PWV is influenced by the body's constitution.

Objective GH1 gene presents a complex map of single nucleotide polymorphisms (SNPs) in the entire promoter, coding and noncoding regions. The aim of the study was to establish the complete map of GH1 gene SNPs in our control normal population and to analyse its association with adult height. Design, subjects and measurements A systematic GH1 gene analysis was designed in a control population of 307 adults of both sexes with height normally distributed within normal range for the same population: −2 standard deviation scores (SDS) to +2 SDS. An analysis was performed on individual and combined genotype associations with adult height. Results Twenty-five SNPs presented a frequency over 1%: 11 in the promoter (P1 to P11), three in the 5′UTR region (P12 to P14), one in exon 1 (P15), three in intron 1 (P16 to P18), two in intron 2 (P19 and P20), two in exon 4 (P21 and P22) and three in intron 4 (P23 to P25). Twenty-nine additional changes with frequencies under 1% were found in 29 subjects. P8, P19, P20 and P25 had not been previously described. P6, P12, P17 and P25 accounted for 6·2% of the variation in adult height (P = 0·0007) in this population with genotypes A/G at P6, G/G at P6 and A/G at P12 decreasing height SDS (−0·063 ± 0·031, −0·693 ± 0·350 and −0·489 ± 0·265, Mean ± SE) and genotypes A/T at P17 and T/G at P25 increasing height SDS (+1·094 ± 0·456 and +1·184 ± 0·432). Conclusions This study established the GH1 gene sequence variation map in a normal adult height control population confirming the high density of SNPs in a relatively small gene. Our study shows that the more frequent SNPs did not significantly contribute to height determination, while only one promoter and two intronic SNPs contributed significantly to it. Studies in larger populations will have to confirm the associations and in vitro functional studies will elucidate the mechanisms involved. Systematic GH1 gene analysis in patients with growth delay and suspected GH deficiency/insufficiency will clarify whether different SNP frequencies and/or the presence of different sequence changes may be associated with phenotypes in them.

Alström syndrome (ALMS) is a rare autosomal recessive monogenic disease included in an emerging class of genetic disorders called 'ciliopathies' and is likely to impact the central nervous system as well as metabolic and endocrine function. Individuals with ALMS present clinical features resembling a growth hormone deficiency (GHD) condition, but thus far no study has specifically investigated this aspect in a large population. Twenty-three patients with ALMS (age, 1-52 years; 11 males, 12 females) were evaluated for anthropometric parameters (growth charts and standard deviation score (SDS) of height, weight, BMI), GH secretion by growth hormone-releasing hormone + arginine test (GHRH-arg), bone age, and hypothalamic-pituitary magnetic resonance imaging (MRI). A group of 17 healthy subjects served as controls in the GH secretion study. Longitudinal retrospective and prospective data were utilized. The length-for-age measurements from birth to 36 months showed normal growth with most values falling within -0·67 SDS to +1·28 SDS. A progressive decrease in stature-for-age was observed after 10 years of age, with a low final height in almost all ALMS subjects (>16-20 years; mean SDS, -2·22 ± 1·16). The subset of 12 patients with ALMS tested for GHRH-arg showed a significantly shorter stature than age-matched controls (154·7 ± 10·6 cm vs 162·9 ± 4·8 cm, P = 0·009) and a mild increase in BMI (Kg/m(2) ) (27·8 ± 4·8 vs 24·1 ± 2·5, P = 0·007). Peak GH after GHRH-arg was significantly lower in patients with ALMS in comparison with controls (11·9 ± 6·9 μg/l vs 86·1 ± 33·2 μg/l, P < 0·0001). Severe GHD was evident biochemically in 50% of patients with ALMS. The 10 adult ALMS patients with GHD showed a reduced height in comparison with those without GHD (149·7 ± 6·2 cm vs 161·9 ± 9·2 cm, P = 0·04). MRIs of the diencephalic and pituitary regions were normal in 11 of 12 patients. Bone age was advanced in 43% of cases. Our study shows that 50% of nonobese ALMS patients have an inadequate GH reserve to GHRH-arg and may be functionally GH deficient. The short stature reported in ALMS may be at least partially influenced by impairment of GH secretion. © 2013 John Wiley & Sons Ltd.

Bone mineral density (BMD) is unknown in children with Prader-Willi syndrome (PWS), but is decreased in adults with PWS. In patients with GH deficiency, BMD increases during GH treatment. The aim of the study was to evaluate BMD in children with PWS and to study the effects of GH treatment. We conducted a randomized controlled GH trial. Forty-six prepubertal children were randomized into either a GH-treated group (1.0 mg/m(2) . d) or a control group for 2 yr. At start, 6, 12, and 24 months of study, total body and lumbar spine BMD were measured by dual-energy x-ray absorptiometry, and lumbar spine bone mineral apparent density (BMAD) was calculated. Baseline total body and lumbar spine BMD sd score (SDS) were normal [mean (sd), -0.2 SDS (1.1) and -0.4 SDS (1.2), respectively]. BMADSDS, which corrects for short stature, was also normal [mean (sd), 0.40 SDS (1.1)]. Total body BMDSDS decreased during the first 6 months of GH (P < 0.0001), but increased during the second year of treatment. After 24 months of study, total body and lumbar spine BMDSDS, and the BMADSDS did not significantly differ between GH-treated children and randomized controls (P = 0.30, P = 0.44, and P = 0.47, respectively). Results were similar when corrected for body mass index SDS. Repeated measurements analysis showed a significant positive association between IGF-I SDS and total body and lumbar spine BMDSDS, but not with BMADSDS. Our results show that prepubertal children with PWS have a normal BMD. GH treatment had no effect on BMD, except for a temporary decrease of total body BMDSDS in the first 6 months.

Intrauterine growth restriction (IUGR) is a risk factor for memory impairment and emotional disturbance during growth and adulthood. However, this risk might be modulated by environmental factors during development. Here we examined whether exposing adolescent male and female rats with thromboxane A2-induced IUGR to social defeat stress (SDS) affected their working memory and anxiety-like behavior in adulthood. We also used BrdU staining to investigate hippocampal cellular proliferation and BrdU and NeuN double staining to investigate neural differentiation in female IUGR rats. In the absence of adolescent stress, IUGR female rats, but not male rats, scored significantly lower in the T-maze test of working memory and exhibited higher anxiety-like behavior in the elevated-plus maze test compared with controls. Adolescent exposure to SDS abolished these behavioral impairments in IUGR females. In the absence of adolescent stress, hippocampal cellular proliferation was significantly higher in IUGR females than in non-IUGR female controls and was not influenced by adolescent exposure to SDS. Hippocampal neural differentiation was equivalent in non-stressed control and IUGR females. Neural differentiation was significantly increased by adolescent exposure to SDS in controls but not in IUGR females. There was no significant difference in the serum corticosterone concentrations between non-stressed control and IUGR females; however, adolescent exposure to SDS significantly increased serum corticosterone concentration in control females but not in IUGR females. These results demonstrate that adolescent exposure to SDS improves behavioral impairment independent of hippocampal neurogenesis in adult rats with IUGR. Copyright © 2015 Elsevier Inc.

To compare test results from second-generation Frequency-Doubling Technology perimetry (FDT2, Humphrey Matrix; Carl-Zeiss Meditec, Dublin, CA) and standard automated perimetry (SAP) in patients with glaucoma. Specifically, to examine the relationship between visual field sensitivity and test-retest variability and to compare total and pattern deviation probability maps between both techniques. Fifteen patients with glaucoma who had early to moderately advanced visual field loss with SAP (mean MD, -4.0 dB; range, +0.2 to -16.1) were enrolled in the study. Patients attended three sessions. During each session, one eye was examined twice with FDT2 (24-2 threshold test) and twice with SAP (Swedish Interactive Threshold Algorithm [SITA] Standard 24-2 test), in random order. We compared threshold values between FDT2 and SAP at test locations with similar visual field coordinates. Test-retest variability, established in terms of test-retest intervals and standard deviations (SDs), was investigated as a function of visual field sensitivity (estimated by baseline threshold and mean threshold, respectively). The magnitude of visual field defects apparent in total and pattern deviation probability maps were compared between both techniques by ordinal scoring. The global visual field indices mean deviation (MD) and pattern standard deviation (PSD) of FDT2 and SAP correlated highly (r > 0.8; P < 0.001). At test locations with high sensitivity (>25 dB with SAP), threshold estimates from FDT2 and SAP exhibited a close, linear relationship, with a slope of approximately 2.0. However, at test locations with lower sensitivity, the relationship was much weaker and ceased to be linear. In comparison with FDT2, SAP showed a slightly larger proportion of test locations with absolute defects (3.0% vs. 2.2% with SAP and FDT2, respectively, P < 0.001). Whereas SAP showed a significant increase in test-retest variability at test locations with lower sensitivity (P < 0.001), there was no relationship between variability and sensitivity with FDT2 (P = 0.46). In comparison with SAP, FDT2 exhibited narrower test-retest intervals at test locations with lower sensitivity (SAP thresholds <25 dB). A comparison of the total and pattern deviation maps between both techniques showed that the total deviation analyses of FDT2 may slightly underestimate the visual field loss apparent with SAP. However, the pattern-deviation maps of both instruments agreed well with each other. The test-retest variability of FDT2 is uniform over the measurement range of the instrument. These properties may provide advantages for the monitoring of patients with glaucoma that should be investigated in longitudinal studies.

Comparison between Procedures using Sodium Dodecyl Sulfate for Shotgun Proteomic Analyses of Complex Samples

Filter aided sample preparation (FASP) and a new sample preparation method using a modified commercial SDS removal spin column are quantitatively compared in terms of their performance for shotgun proteomic experiments in three complex proteomic samples: a Saccharomyces cerevisiae lysate (insoluble fraction), a Caenorhabditis elegans lysate (soluble fraction), and a human embryonic kidney cell line (HEK293T). The characteristics and total number of peptides and proteins identified are compared between the two procedures. The SDS spin column procedure affords a conservative 4-fold improvement in throughput, is more reproducible, less expensive (i.e., requires less materials), and identifies between 30–107% more peptides at a q≤0.01, than the FASP procedure. The peptides identified by SDS spin column are more hydrophobic than species identified by the FASP procedure as indicated by the distribution of GRAVY scores. Ultimately, these improvements correlate to as great as a 50% increase in protein identifications with 2 or more peptides. PMID:21656683

Fish species inhabitating seawater (SW) or freshwater (FW) habitats have to develop genetic adaptations to alternative environment factors, especially salinity. Functional consequences of the protein variations associated with habitat environments in fish mitochondrial genomes have not yet received much attention. We analyzed 829 complete fish mitochondrial genomes and compared the amino acid differences of 13 mitochondrial protein families between FW and SW fish groups. We identified 47 specificity determining sites (SDS) that associated with FW or SW environments from 12 mitochondrial protein families. Thirty-two (68%) of the SDS sites are hydrophobic, 13 (28%) are neutral, and the remaining sites are acidic or basic. Seven of those SDS from ND1, ND2 and ND5 were scored as probably damaging to the protein structures. Furthermore, phylogenetic tree based Bayes Empirical Bayes analysis also detected 63 positive sites associated with alternative habitat environments across ten mtDNA proteins. These signatures could be important for studying mitochondrial genetic variation relevant to fish physiology and ecology.

The study aimed to explore and analyze the effects of health education intervention on patients with laryngeal cancer and evaluate negative emotions and quality of life after receiving postoperative radiotherapy. Furthermore the relationship between health education intervention methods and its correlation to complications and relapse rates require greater understanding. Patients with aryngeal cancer receiving surgery and postoperative radiotherapy were randomly divided into observation and control groups. A quality of life questionnaire was used to evaluate patients' current life quality as well as negative emotions experienced. The collected data was evaluated using the Self-rating Anxiety Scale (SAS) as well as the Self-rating Depression Scale (SDS). At the time of discharge, patients' satisfaction on nursing and perception of health knowledge was assessed. Three and six months after discharge, patients were given follow-up visits and questionnaire surveys to evaluate their rehabilitation. This was done in relation with the Morningside Rehabilitation Stats Scale (MRSS), incidence of complications and recurrence. The scores of negative emotions, exhibited during the study, were lower in the observation group than in the control group. A month after discharge had a positive correlation to improved quality of life. This was highlighted in the observation group in comparison with the control group. The data collected following discharge revealed an improvement in quality of life, compared with that at the time of admission. Compared with the control group, the SAS and SDS scores in the observation group were decreased a month after discharge. Compared with the scores on admission, the SAS and SDS scores in both groups were decreased one month after discharge. The observation group had a lower incidence of complications than that of the control group. Six months after discharge, in the observation group, the MRSS score was lower than before discharge while in the control group, the MRSS score was higher than before discharge. Health education intervention can significantly improve the quality of life and reduce experiences relating to negative emotion in patients with laryngeal cancer. This improvement was seen following surgery and radiotherapy. Additionally effective reduction rates in the incidence of postoperative complications and recurrence were exhibited following methods of health education intervention.

We investigated the influencing factors of the psychological resilience and self-efficacy of acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI) and the relationships of psychological resilience and self-efficacy with negative emotion. Eighty-eight participants were enrolled. Psychological resilience, self-efficacy, and negative emotion were assessed with the Psychological Resilience Scale, Self-Efficacy Scale, Zung Self-Rating Anxiety Scale (SAS), and Zung Self-Rating Depression Scale (SDS), respectively. Furthermore, the relationships of psychological resilience and self-efficacy with negative emotion were investigated. The average scores of psychological resilience, self-efficacy, anxiety, and depression were 70.08 ± 13.26, 21.56 ± 9.66, 53.68 ± 13.10, and 56.12 ± 12.37, respectively. The incidences of anxiety and depression were 23.90% (21/88) and 28.40% (25/88), respectively. The psychological resilience and self-efficacy scores of AMI patients after PCI varied significantly with age and economic status. SAS scores and SDS scores were significantly negatively correlated with psychological resilience and self-efficacy. Negative emotions in AMI patients after PCI are closely related to psychological resilience and self-efficacy. Therefore, anxiety and depression could be alleviated by improving the psychological resilience and self-efficacy of patients undergoing PCI, thus improving patients' quality of life.

Reportedly, fibromyalgia (FM) is frequently associated with reduced IGF-1 levels and GH hyporesponsiveness to different GH stimulation tests. Since there is a high prevalence of obesity in FM, and obesity itself is characterized by hyposomatotropism, the aim of this study was to assess IGF-1 levels and GH responsiveness in sixteen severely obese women suffering from FM, who, subdivided into two subgroups on the basis of their age-dependent IGF-1 values (> or <-2 SDS), underwent the combined GHRH plus arginine test. Four out of 16 obese women with FM (25%) had low IGF-1 SDS values, 2 cases of this subgroup (12.5%) failing also to normally respond to the test. Among patients with normal GH responses, 4 showed a delayed GH peak. The subgroup with low IGF-1 SDS values had higher BMI than that with normal IGF-1 SDS. GH peak and area under the curve were not correlated with CRP, ESR, or tender point score, while significant correlations were found with fat-free mass and fat mass. In conclusion, this study shows the existence of a high prevalence of GH-IGF-1 dysfunction in patients with both FM and obesity, presumably as a consequence of the obese rather than fibromyalgic condition.

We validate the Ozone Monitoring Instrument (OMI) Ozone Profile (PROFOZ) product from October 2004 through December 2014 retrieved by the Smithsonian Astrophysical Observatory (SAO) algorithm against ozonesonde observations. We also evaluate the effects of OMI row anomaly (RA) on the retrieval by dividing the dataset into before and after the occurrence of serious OMI RA, i.e., pre-RA (2004-2008) and post-RA (2009-2014). The retrieval shows good agreement with ozonesondes in the tropics and midlatitudes and for pressure < ˜ 50 hPa in the high latitudes. It demonstrates clear improvement over the a priori down to the lower troposphere in the tropics and down to an average of ˜ 550 (300) hPa at middle (high) latitudes. In the tropics and midlatitudes, the profile mean biases (MBs) are less than 6 %, and the standard deviations (SDs) range from 5 to 10 % for pressure < ˜ 50 hPa to less than 18 % (27 %) in the tropics (midlatitudes) for pressure > ˜ 50 hPa after applying OMI averaging kernels to ozonesonde data. The MBs of the stratospheric ozone column (SOC, the ozone column from the tropopause pressure to the ozonesonde burst pressure) are within 2 % with SDs of < 5 % and the MBs of the tropospheric ozone column (TOC) are within 6 % with SDs of 15 %. In the high latitudes, the profile MBs are within 10 % with SDs of 5-15 % for pressure < ˜ 50 hPa but increase to 30 % with SDs as great as 40 % for pressure > ˜ 50 hPa. The SOC MBs increase up to 3 % with SDs as great as 6 % and the TOC SDs increase up to 30 %. The comparison generally degrades at larger solar zenith angles (SZA) due to weaker signals and additional sources of error, leading to worse performance at high latitudes and during the midlatitude winter. Agreement also degrades with increasing cloudiness for pressure > ˜ 100 hPa and varies with cross-track position, especially with large MBs and SDs at extreme off-nadir positions. In the tropics and midlatitudes, the post-RA comparison is considerably worse with larger SDs reaching 2 % in the stratosphere and 8 % in the troposphere and up to 6 % in TOC. There are systematic differences that vary with latitude compared to the pre-RA comparison. The retrieval comparison demonstrates good long-term stability during the pre-RA period but exhibits a statistically significant trend of 0.14-0.7 % year-1 for pressure < ˜ 80 hPa, 0.7 DU year-1 in SOC, and -0. 33 DU year-1 in TOC during the post-RA period. The spatiotemporal variation of retrieval performance suggests the need to improve OMI's radiometric calibration especially during the post-RA period to maintain the long-term stability and reduce the latitude/season/SZA and cross-track dependency of retrieval quality.

Improving IQ measurement in intellectual disabilities using true deviation from population norms

PubMed Central

2014-01-01

Background Intellectual disability (ID) is characterized by global cognitive deficits, yet the very IQ tests used to assess ID have limited range and precision in this population, especially for more impaired individuals. Methods We describe the development and validation of a method of raw z-score transformation (based on general population norms) that ameliorates floor effects and improves the precision of IQ measurement in ID using the Stanford Binet 5 (SB5) in fragile X syndrome (FXS; n = 106), the leading inherited cause of ID, and in individuals with idiopathic autism spectrum disorder (ASD; n = 205). We compared the distributional characteristics and Q-Q plots from the standardized scores with the deviation z-scores. Additionally, we examined the relationship between both scoring methods and multiple criterion measures. Results We found evidence that substantial and meaningful variation in cognitive ability on standardized IQ tests among individuals with ID is lost when converting raw scores to standardized scaled, index and IQ scores. Use of the deviation z- score method rectifies this problem, and accounts for significant additional variance in criterion validation measures, above and beyond the usual IQ scores. Additionally, individual and group-level cognitive strengths and weaknesses are recovered using deviation scores. Conclusion Traditional methods for generating IQ scores in lower functioning individuals with ID are inaccurate and inadequate, leading to erroneously flat profiles. However assessment of cognitive abilities is substantially improved by measuring true deviation in performance from standardization sample norms. This work has important implications for standardized test development, clinical assessment, and research for which IQ is an important measure of interest in individuals with neurodevelopmental disorders and other forms of cognitive impairment.

A new method for solid-phase extraction and preconcentration of trace amounts Hg(II) from environmental samples was developed by using sodium dodecyle sulphate-coated magnetite nanoparticles (SDS-coated Fe(3)O(4) NPs) as a new extractant. The procedure is based on the adsorption of the analyte, as mercury-Michler's thioketone [Hg(2)(TMK)(4)](2+) complex on the negatively charged surface of the SDS-coated Fe(3)O(4) NPs and then elution of the preconcentrated mercury from the surface of the SDS-coated Fe(3)O(4) NPs prior to its determination by flow injection inductively coupled plasma-optical emission spectrometry. The effects of pH, TMK concentration, SDS and Fe(3)O(4) NPs amounts, eluent type, sample volume and interfering ions on the recovery of the analyte were investigated. Under optimized conditions, the calibration curve was linear in the range of 0.2-100ngmL(-1) with r(2)=0.9994 (n=8). The limit of detection for Hg(II) determination was 0.04ngmL(-1). Also, relative standard deviation (R.S.D.) for the determination of 2 and 50ngmL(-1) of Hg(II) was 5.2 and 4.7% (n=6), respectively. Due to the quantitative extraction of Hg(II) from 1000mL of the sample solution an enhancement factor as large as 1230-fold can be obtained. The proposed method has been validated using a certified reference materials, and also the method has been applied successfully for the determination of Hg(II) in aqueous samples.

To determine depression in patients with choroidal melanoma (CM) treated with proton beam radiotherapy. This was a cross-sectional study including 50 patients with CM (50% males, mean age=49.88±6.34 years) and 46 age- and sex-matched healthy controls (52% males, mean age=48.60±8.05 years). Participants completed the Patient Health Questionnaire-9 (PHQ-9) and the Zung Self-Rating Depression Scale (SDS) questionnaires. There was a considerable difference in visual acuity as logarithm of the minimum angle of resolution (logMAR) between the patient and control groups (1.16±0.97 and 0.04±0.05 logMAR, respectively, p<0.0001). Both PHQ-9 and SDS scores differed significantly between the two groups (10.18±4.68 and 8.07±4.90, p=0.04; and 47.94±12.56 and 39.91±8.80, p=0.004, respectively). Scores appeared to be positively correlated with logMAR visual acuity (Spearman rho=0.700, p<0.0001 for PHQ-9; and 0.767, p<0.0001 for SDS), and they were also correlated to each other (Spearman rho=0.759, p<0.0001). Patients with CM having undergone proton beam therapy seem to be more depressed compared to a sample of healthy individuals, and the level of depression is correlated with their visual acuity.

Micellar electrokinetic chromatography with acid labile surfactant.

PubMed

Stanley, Bob; Lucy, Charles A

2012-02-24

We present a study of a degradable surfactant, sodium 4-[(2-methyl-2-undecyl-1,3-dioxolan-4-yl)methoxy]-1-propane sulfonate that is also known as an acid-labile surfactant (ALS). The performance of ALS as a pseudostationary phase is assessed and compared with established pseudostationary phases such as sodium dodecyl sulphate (SDS), volatile surfactants and polymeric micelles. ALS achieves separation efficiency of 100,000-145,000 theoretical plates and relative standard deviation (RSD) of electrophoretic mobility (n=5) of less than 3%. Retention factors with ALS are strongly correlated with those with SDS. This is shown by the R2=0.79 for all eleven analytes and an R2=0.992 for specifically the non-hydrogen bonding (NHB) analytes. However, ALS displays different selectivity than SDS for hydrogen bond donor (HBD) and hydrogen bond acceptor (HBA) solutes (R2 of 0.74 and 0.88, respectively). ALS is degraded to less surface active compounds in acidic solution. These less surface-active compounds are more compatible with the electrospray ionization mass spectrometry (ESI-MS). ALS has a half-life of 48 min at pH 4. ALS has the potential to couple micellar electrokinetic chromatography (MEKC) with the ESI-MS. ALS can be used as a pseudostationary phase for a high efficiency separation and later acid hydrolyzed to enable an ESI-MS analysis. Copyright © 2011 Elsevier B.V. All rights reserved.

Very little information is available on whether docosahexaenoic acid (DHA) supplementation has a beneficial effect on liver fat and cardiovascular disease (CVD) risk factors in children with nonalcoholic fatty liver disease (NAFLD). In a double-blind, placebo-controlled randomized trial we investigated whether 6-month treatment with DHA improves hepatic fat and other fat depots, and their associated CVD risk factors in children with biopsy-proven NAFLD. Of 58 randomized children, 51 (25 DHA, 26 placebo) completed the study. The main outcome was the change in hepatic fat fraction as estimated by magnetic resonance imaging. Secondary outcomes were changes in visceral adipose tissue (VAT), epicardial adipose tissue (EAT), and left ventricular (LV) function, as well as alanine aminotransferase (ALT), triglycerides, body mass index-standard deviation score (BMI-SDS), and insulin sensitivity. At 6 months, the liver fat was reduced by 53.4% (95% CI, 33.4-73.4) in the DHA group, as compared with 22.6% (6.2-39.0) in the placebo group (P = 0.040 for the comparison between the two groups). Likewise, in the DHA group VAT and EAT were reduced by 7.8% (0-18.3) and 14.2% (0-28.2%), as compared with 2.2% (0-8.1) and 1.7% (0-6.8%) in the placebo group, respectively (P = 0.01 for both comparisons). There were no significant between-group changes for LV function as well as BMI-SDS and ALT, while fasting insulin and triglycerides significantly decreased in the DHA-treated children (P = 0.028 and P = 0.041, respectively). DHA supplementation decreases liver and visceral fat, and ameliorates metabolic abnormalities in children with NAFLD. Copyright © 2015 Elsevier B.V. All rights reserved.

To assess glycaemic control, anthropometry and insulin regimens in a national sample of Australian children and adolescents with type 1 diabetes. Cross-sectional analysis of de-identified, prospectively collected data from the Australasian Diabetes Data Network (ADDN) registry. Five paediatric diabetes centres in New South Wales, Queensland, South Australia, Victoria and Western Australia. Children and adolescents (aged 18 years or under) with type 1 diabetes of at least 12 months' duration for whom data were added to the ADDN registry during 2015. Glycaemic control was assessed by measuring haemoglobin A1c (HbA1c) levels. Body mass index standard deviation scores (BMI-SDS) were calculated according to the CDC-2000 reference; overweight and obesity were defined by International Obesity Task Force guidelines. Insulin regimens were classified as twice-daily injections (BD), multiple daily injections (MDI; at least three injection times per day), or continuous subcutaneous insulin infusion (CSII). The mean age of the 3279 participants was 12.8 years (SD, 3.7), mean diabetes duration was 5.7 years (SD, 3.7), and mean HbA1c level 67 mmol/mol (SD, 15); only 27% achieved the national HbA1c target of less than 58 mmol/mol. The mean HbA1c level was lower in children under 6 (63 mmol/mol) than in adolescents (14-18 years; 69 mmol/mol). Mean BMI-SDS for all participants was 0.6 (SD, 0.9); 33% of the participants were overweight or obese. 44% were treated with CSII, 38% with MDI, 18% with BD. Most Australian children and adolescents with type 1 diabetes are not meeting the recognised HbA1c target. The prevalence of overweight and obesity is high. There is an urgent need to identify barriers to achieving optimal glycaemic control in this population.

Objective: To evaluate the clinical signs and symptoms that would help clinicians to consider pseudohypoparathyroidism (PHP) type 1A as a diagnosis in a child. Methods: A retrospective review of the medical records of children diagnosed by erythrocyte Gsα activity and/or GNAS1 gene study and followed-up for PHP type 1A. Clinical and biochemical parameters along with epidemiological data were extracted and analyzed. Weight gain during infancy and early childhood was calculated as change in weight standard deviation score (SDS), using the French growth reference values. An upward gain in weight ≥0.67 SDS during these periods was considered indicative of overweight and/or obesity. Results: Ten cases of PHP type 1A were identified (mean age 41.1 months, range from 4 to 156 months). In children aged ≤2 years, the commonest clinical features were round lunar face, obesity (70%), and subcutaneous ossifications (60%). In older children, brachydactyly was present in 60% of cases. Seizures occurred in older children (3 cases). Short stature was common at all ages. Subclinical hypothyroidism was present in 70%, increased parathormone (PTH) in 83%, and hyperphosphatemia in 50%. Only one case presented with hypocalcemia. Erythrocyte Gsα activity tested in seven children was reduced; GNAS1 gene testing was performed in 9 children. Maternal transmission was the most common (six patients). In three other cases, the mutations were de novo, c.585delGACT in exon 8 (case 2) and c.344C>TP115L in exon 5 (cases 6&7). Conclusion: Based on our results, PHP type 1A should be considered in toddlers presenting with round face, rapid weight gain, subcutaneous ossifications, and subclinical hypothyroidism. In older children, moderate mental retardation, brachydactyly, afebrile seizures, short stature, and thyroid-stimulating hormone resistance are the most suggestive features. PMID:27467896

With increasing obesity in childhood and adolescence, weight gain, and insulin resistance become also more frequent in patients with type 1 diabetes mellitus (T1DM). Especially during puberty, insulin therapy often has to be intensified and higher insulin doses are necessary. Some studies point to a beneficial effect of metformin in addition to insulin in these patients. In order to describe current practice and possible benefits, we compared pediatric T1DM patients with insulin plus metformin (n = 525) to patients with insulin therapy only (n = 57 487) in a prospective multicenter analysis. Auxological and treatment data from 58 012 patients aged <21 yr with T1DM in the German/Austrian Diabetes Patienten Verlaufsdokumentation (DPV) registry were analyzed by multivariable mixed regression modeling. Patients with additional metformin were older [median (interquartile range)]: [16.1 (14.1-17.6) vs. 15.2 (11.5-17.5) yr] with female preponderance (61.0 vs. 47.2%, p < 0.01). They had higher body mass index-standard deviation score (BMI-SDS) [+2.03 (+1.29 to +2.56) vs. +0.51 (-0.12 to +1.15); p < 0.01] and glycated hemoglobin (HbA1c) (9.0 vs. 8.6%, p < 0.01). Hypertension (43.7 vs. 24.8%) and dyslipidemia (58.4 vs. 40.6%) were significantly more prevalent. Adjusted insulin dose was significantly higher (0.98 vs. 0.93 IU/kg bodyweight). In a subgroup of 285 patients followed-up longitudinally (average treatment period 1.42 yr), addition of metformin resulted in a slight reduction of BMI-SDS [-0.01 (-2.01 to +1.40)], but did not improve HbA1c or insulin requirement. Additional metformin therapy in T1DM is primarily used in obese females. Additional therapy with metformin was associated with minor benefits. © 2014 John Wiley & Sons A/S.

The influences of obesity, glucose metabolism, gender, and puberty on betatrophin levels and the longitudinal relationships between weight loss, metabolic changes and betatrophin have not yet been studied in childhood. Cross-sectional and longitudinal analysis of weight status (standard deviation score-body mass index (SDS-BMI)), homeostasis model assessment insulin resistance (HOMA-IR), gender, and pubertal stage were evaluated in 69 obese children (51% female, age 11.9 ± 2.0 years) participating in lifestyle intervention over a 1-year period. An oral glucose tolerance test was performed in 53 of the 69 children. Twenty normal weight children (50% female, age 12.3 ± 3.0 years) served as controls. Circulating betatrophin did not differ significantly between obese and lean children (1.99 ± 0.90 vs 2.35 ± 0.28, mean ± SD, P = .155). At baseline, betatrophin did not differ in obese patients with vs without glucose intolerance (1.89 ± 0.96 vs 2.031 ± 0.91 ng/mL; P = .591) and obese with (delta SDS-BMI >0.4) vs without successful obesity intervention (1.89 ± 0.94 vs. 2.07 ± 0.87 ng/mL; P = 0.396). In multiple linear regression analyses, pubertal stage was associated with betatrophin (b: 0.48, P = .027), while gender, age, BMI, blood pressure, fasting glucose, HOMA-IR, triglycerides, LDL- and HDL-cholesterol were not related to betatrophin at baseline. At the end of the 1-year intervention, changes of betatrophin were not significantly associated with any parameter after controlling for multiple covariates including age and changes of pubertal stages. Our data do not support a relationship between betatrophin and weight status or glucose tolerance, insulin resistance, and lipid metabolism in children. © 2016 John Wiley & Sons A/S.

Longitudinal data on bone mineral density (BMD) in children and adolescents with Prader-Willi Syndrome (PWS) during long-term GH treatment are not available. This study aimed to determine effects of long-term GH treatment and puberty on BMD of total body (BMDTB), lumbar spine (BMDLS), and bone mineral apparent density of the lumbar spine (BMADLS) in children with PWS. This was a prospective longitudinal study of a Dutch PWS cohort. Seventy-seven children with PWS who remained prepubertal during GH treatment for 4 years and 64 children with PWS who received GH treatment for 9 years participated in the study. The children received GH treatment, 1 mg/m(2)/day (≅ 0.035 mg/kg/d). BMDTB, BMDLS, and BMADLS was measured by using the same dual-energy x-ray absorptiometry machine for all annual measurements. In the prepubertal group, BMDTB standard deviation score (SDS) and BMDLSSDS significantly increased during 4 years of GH treatment whereas BMADLSSDS remained stable. During adolescence, BMDTBSDS and BMADLSSDS decreased significantly, in girls from the age of 11 years and in boys from the ages of 14 and 16 years, respectively, but all BMD parameters remained within the normal range. Higher Tanner stages tended to be associated with lower BMDTBSDS (P = .083) and a significantly lower BMADLSSDS (P = .016). After 9 years of GH treatment, lean body mass SDS was the most powerful predictor of BMDTBSDS and BMDLSSDS in adolescents with PWS. This long-term GH study demonstrates that BMDTB, BMDLS, and BMADLS remain stable in prepubertal children with PWS but decreases during adolescence, parallel to incomplete pubertal development. Based on our findings, clinicians should start sex hormone therapy from the age of 11 years in girls and 14 years in boys unless there is a normal progression of puberty.

Objective: Obesity affects almost all systems in the body. This includes the retinal nerve fibers which may be damaged due to a chronic inflammatory process. To determine changes in retinal nerve fiber layer (RNFL) thickness in non-diabetic children and adolescents using optical coherence tomography (OCT) and to evaluate the relationship between this change, metabolic risk factors and pubertal stage. Methods: Thirty-eight obese and 40 healthy children and adolescents aged 10-18 years were included in the study. RNFL measurements from the optic disk and all surrounding quadrants were obtained using OCT from both eyes of the individuals in the study groups. Correlations between RNFL thickness and age, auxological measurements, pubertal stage, systolic and diastolic blood pressure, homeostasis model assessment-insulin resistance (HOMA-IR) index and lipid values were investigated. Results: A general decrease was observed in RNFL thickness in obese subjects compared to the controls, the decrease being highest in the inferior quadrant, although these differences were not statistically significant (p>0.05). RNFL thickness was negatively correlated with body mass index (BMI) standard deviation score (SDS) in both groups (control group r=-0.345, p=0.029; obese group r=-0.355, p=0.022). Significant negative correlations were determined between diastolic blood pressure, HOMA-IR, low density lipoprotein cholesterol level and RNFL thickness (r=-0.366, p=0.024; r=-0.394, p=0.016; and r=-0.374, p=0.022, respectively) in the obese group, while there was no association between these parameters and RNFL thickness in the control group. Conclusion: In this cross-sectional study, no statistically significant difference in RNFL thicknesses between the obese and control groups was determined. However, RNFL thickness was found to decrease in both healthy and obese children as BMI-SDS values increased. Further prospective studies may be of benefit to determine whether the decrease in RNFL values might become more pronounced on long-term follow-up. PMID:28739552

Human growth is an elementary process which starts at conception and continues through different stages of development under the influence of growth hormone (GH) secreted by the anterior pituitary gland. Variation affecting the production, release and functional activity of GH leads to growth hormone deficiency (GHD), which is of two types: isolated growth hormone deficiency (IGHD) and combined pituitary hormone deficiency (CPHD). IGHD may result from mutations in GH1 and GHRHR while CPHD is associated with defects in transcription factor genes PROP1, POU1F1 and HESX1. The present study reports on the molecular screening of GHRHR and GH1 in IGHD patients. A total of 116 clinically diagnosed IGHD patients and 100 controls were enrolled for the study after taking informed consent. Family history was noted and 5ml blood sample was drawn. Anatomical and/or morphological pituitary gland alterations were studied using magnetic resonance imaging (MRI). DNA from blood samples was processed for screening the GHRHR and GH1 by Sanger sequencing. Mean age at presentation of the 116 patients (67 males and 49 females) was 11.71±3.5years. Mean height standard deviation score (SDS) and weight SDS were -4.5 and -3.5 respectively. Nine (7.8%) were familial and parental consanguinity was present in 21 (19.8%) families. Eighty-three patients underwent MRI and morphological alterations of the pituitary were observed in 39 (46.9%). GH1 and GHRHR screening revealed eleven variations in 24 (21%) patients of which, four were novel deleterious, one novel non-pathogenic and six reported changes. GHRHR contributed more to IGHD in our patients which confirmed that GHRHR should be screened first before GH1 in our population. Identification of GH1 and GHRHR variations helped in defining our mutational spectrum which will play a crucial role in providing predictive and prenatal genetic testing to the patients.

Psycho-behavioural inhibition is characteristic of major depressive disorder and frequently recedes after the other depressive symptoms. This may induce an important psychosocial impairment which could be a risk factor for relapse. The aim of this eight weeks, multicentric, randomized, double blind, placebo controlled trial was to assess the efficacy and safety of sulbutiamine (Arcalion) [600 mg p.d.] on the symptoms of psycho-behavioural inhibition of inpatients with DSM III-R defined Major Depressive Episode (MDE) treated by adjusted doses of clomipramine [75 to 150 mg pd]. Moderate doses of hypnotics and anxiolytics without potential activity on the mood were authorized during the trial. The MDE was assessed with the MADRS, HAM-A and CGI scales. Patients who did not respond adequately to the antidepressant treatment were prematurely withdrawn from the trial. The three Sheehan Disability Scales (SDS), the Norris Visual Analogue Scale (VAS) and the Depressive Psychomotor Retardation Scale (ERD) were used to monitor psycho-behavioural inhibition. The mean intake scores were, as expected, fairly high: MADRS (32), HAMA-A (23), CGI (5) and ERD (27). The SDS and EVA scores showed that the patients felt severely handicapped in their social, professional and family life functioning as well as in their emotional, affective, cognitive and behavioural performances. At four weeks the MADRS, HAM-A and CGI scores indicated that the global improvement of the MDE was comparable in both treatment groups. However, the scores at the EVA and SDS scales showed that the patients treated with sulbutiamine were significantly less incapacitated than the placebo group in all of the various facets (affective, cognitive, emotional, behavioural) of psycho-behavioural inhibition. Furthermore, the safety data shows that both treatment groups were comparable and in particular that sulbutiamine had not induced any inappropriate behaviour, including suicide attempts, or mania. Sulbutiamine has no antidepressive effect but it can hasten the resorption of psycho-behavioural inhibition occurring during major depressive disorder and thereby facilitate the rehabilitation of patients in their social, professional and family life functioning.

To assess effect of acupuncture combined with massage of sole on sleeping quality of the patient with insomnia. Fifty-eight cases of insomnia were randomly divided into an observation group (n = 32) and a control group (n = 26). The observation group were treated with oral administration of Alprazolam, massage of sole, and acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), etc. on the abdomen as main points; the control group were treated with Alprazolam. Clinical therapeutic effects, and scores for Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were assessed before and after treatment in the two groups. The effective rate was 93.75 in the observation group and 88.46% in the control group with no significant difference between the two groups; after treatment, there were significant or very significant differences in scores for various factors in the PSQI, SAS and SDS (P < 0.01, P < 0.05). Abdominal acupuncture as main combined with massage of sole can obviously improve sleeping quality of the patient with insomnia.

The purpose of this study was to determine if a brief 10-item alcohol-related Facebook® activity (ARFA) questionnaire would predict alcohol use patterns in college students (N = 146). During a single laboratory session, participants first privately logged on to their Facebook® profiles while they completed the ARFA measure, which queries past 30 day postings related to alcohol use and intoxication. Participants were then asked to complete five additional questionnaires: three measures of alcohol use (the Alcohol Use Disorders Identification Test [AUDIT], the Timeline Follow-Back [TLFB], and the Personal Drinking Habits Questionnaire [PDHQ]), the Barratt Impulsiveness Scale (BIS-11), and the Marlowe-Crowne Social Desirability Scale (MC-SDS). Regression analyses revealed that total ARFA scores were significant predictors of recent drinking behaviors, as assessed by the AUDIT, TLFB, and PDHQ measures. Moreover, impulsivity (BIS-11) and social desirability (MC-SDS) did not predict recent drinking behaviors when ARFA total scores were included in the regressions. The findings suggest that social media activity measured via the ARFA scale may be useful as a research tool for identifying risky alcohol use. PMID:28138317

To evaluate the efficacy and safety of combined selective serotonin reuptake inhibitors (SSRIs) and electroacupuncture therapies for the early treatment of primary depression. Randomized controlled trials (RCTs) were analyzed to compare therapy combining SSRIs and electroacupuncture to SSRI therapy alone. The RCTs were identified by searching, among others, PubMed, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Chongqing VIP database for Chinese Technical Periodicals, WANFANG DATA, and the Chinese Biological Medical Literature Database. Scores from Self-Rated Depression Scale (SDS), the Hamilton Depression Scale (HAMD), the Side Effect Rating Scale (SERS), and the Treatment Emergent Symptom Scale (TESS) were analyzed and coded by two independent investigators and used to evaluate the safety and efficacy of treatment. Statistical analyses were performed using RevMan 5.2 software. Six RCTs were analyzed. The meta-analysis revealed that the combined therapy of SSRIs and electroacupuncture were associated with superior scores on the HAMD, SDS, and SERS measures compared with SSRIs alone after 1-4 weeks of treatment: HAMD scores, mean difference (MD)(1 week), 2.32 (95% confidence interval [CI](1 week), 1.47-3.16, p(1 week)<0.00001); MD(2 weeks), 2.65 (95% CI(2 weeks), 1.81- 3.50, p(2 weeks)<0.00001); MD(4 weeks), 2.70 (95% CI(4 weeks), 1.90-3.51, p(4 weeks)<0.00001); SDS scores: MD(1 week), 3.13 (95% CI(1 week), 1.22-5.03, p(1 week) = 0.001); MD(2 weeks), 4.05 (95% CI(2 weeks), 0.22-7.87, p(2 weeks) = 0.04); MD(4 weeks), 5.02 (95% CI(4 weeks), 1.61-8.43, p(4 weeks) = 0.004); SERS scores: MD(2 weeks), 2.20 (95% CI(2 weeks), 1.43-2.96, p(2 weeks)<0.00001); MD(4 weeks), 2.12 (95% CI(4 weeks), 1.42-2.83, p(4 weeks)<0.00001). However, two of the aforementioned outcomes were rated as medium quality because of heterogeneity, as assessed using the Grading of Recommendations Assessment, Development and Evaluation system. The available evidence suggests that the early treatment of primary depression using both SSRI and electroacupuncture therapies is more efficient than treatments with SSRIs alone and leads to a better and earlier control of depressive symptoms.

MetaMQAP: a meta-server for the quality assessment of protein models.

Computational models of protein structure are usually inaccurate and exhibit significant deviations from the true structure. The utility of models depends on the degree of these deviations. A number of predictive methods have been developed to discriminate between the globally incorrect and approximately correct models. However, only a few methods predict correctness of different parts of computational models. Several Model Quality Assessment Programs (MQAPs) have been developed to detect local inaccuracies in unrefined crystallographic models, but it is not known if they are useful for computational models, which usually exhibit different and much more severe errors. The ability to identify local errors in models was tested for eight MQAPs: VERIFY3D, PROSA, BALA, ANOLEA, PROVE, TUNE, REFINER, PROQRES on 8251 models from the CASP-5 and CASP-6 experiments, by calculating the Spearman's rank correlation coefficients between per-residue scores of these methods and local deviations between C-alpha atoms in the models vs. experimental structures. As a reference, we calculated the value of correlation between the local deviations and trivial features that can be calculated for each residue directly from the models, i.e. solvent accessibility, depth in the structure, and the number of local and non-local neighbours. We found that absolute correlations of scores returned by the MQAPs and local deviations were poor for all methods. In addition, scores of PROQRES and several other MQAPs strongly correlate with 'trivial' features. Therefore, we developed MetaMQAP, a meta-predictor based on a multivariate regression model, which uses scores of the above-mentioned methods, but in which trivial parameters are controlled. MetaMQAP predicts the absolute deviation (in Angströms) of individual C-alpha atoms between the model and the unknown true structure as well as global deviations (expressed as root mean square deviation and GDT_TS scores). Local model accuracy predicted by MetaMQAP shows an impressive correlation coefficient of 0.7 with true deviations from native structures, a significant improvement over all constituent primary MQAP scores. The global MetaMQAP score is correlated with model GDT_TS on the level of 0.89. Finally, we compared our method with the MQAPs that scored best in the 7th edition of CASP, using CASP7 server models (not included in the MetaMQAP training set) as the test data. In our benchmark, MetaMQAP is outperformed only by PCONS6 and method QA_556 - methods that require comparison of multiple alternative models and score each of them depending on its similarity to other models. MetaMQAP is however the best among methods capable of evaluating just single models. We implemented the MetaMQAP as a web server available for free use by all academic users at the URL https://genesilico.pl/toolkit/

We describe the effects of recombinant hGH (r-hGH) therapy for up to 6 y on stature and body proportions of 35 children with achondroplasia (Ach). Consecutive height (Ht) measurements were plotted on disease-specific Ach growth curves, but age and sex SD scores (SDS) of Ht, sitting Ht, subischial leg length, and Ht velocity were made with respect to Tanner normal standards. r-hGH was administered by daily subcutaneous injections at a median (range) dose of 30 (15.8-40) U/m2 per week [0.06 (0.04-0.08) mg.kg(-1).24 h(-1)]. Patients were treated for 3 (1-6) y from age 2.25 (1.2-9.3) y. Before treatment, Ht SDS was -4.6 (-6.5 to -3.24). Treatment caused a significant increase in Ht SDS year to year until y 4 (ANOVA F = 46.94; p < 0.01) that was subsequently sustained with no significant further change (y 5 and 6 versus y 4, p > 0.05). When the response to r-hGH was also expressed as a change in Ht velocity, there was a significant increase in the first year of therapy that was maintained over subsequent treatment years (ANOVA = 4.28, p = 0.001). Age was the most important variable accounting for the first-year response in Ht SDS (r2 = 0.41, p < 0.001), and dose of r-hGH did not influence this. Increments in sitting Ht SDS were greater than subischial leg length SDS (F = 26.25, p < 0.001; F = 9.04, p < 0.001, respectively). r-hGH treatment improved the Ht position of Ach children relative to their normal and Ach peers without obvious side effects. A young age at initiation of therapy prevented the characteristic Ht deficit from accumulating. The greater increase in spinal Ht accentuated the existing disproportion. The addition of later surgical leg lengthening could offer the possibility of proportionate adult stature just within the normal range.

Stigma plays in an important role in the lives of persons affected by neglected tropical diseases, and assessment of stigma is important to document this. The aim of this study is to test the cross-cultural validity of the Community Stigma Scale (EMIC-CSS) and the Social Distance Scale (SDS) in the field of leprosy in Cirebon District, Indonesia. Cultural equivalence was tested by assessing the conceptual, item, semantic, operational and measurement equivalence of these instruments. A qualitative exploratory study was conducted to increase our understanding of the concept of stigma in Cirebon District. A process of translation, discussions, trainings and a pilot study followed. A sample of 259 community members was selected through convenience sampling and 67 repeated measures were obtained to assess the psychometric measurement properties. The aspects and items in the SDS and EMIC-CSS seem equally relevant and important in the target culture. The response scales were adapted to ensure that meaning is transferred accurately and no changes to the scale format (e.g. lay out, statements or questions) of both scales were made. A positive correlation was found between the EMIC-CSS and the SDS total scores (r=0.41). Cronbach's alphas of 0.83 and 0.87 were found for the EMIC-CSS and SDS. The exploratory factor analysis indicated for both scales an adequate fit as unidimensional scale. A standard error of measurement of 2.38 was found in the EMIC-CSS and of 1.78 in the SDS. The test-retest reliability coefficient was respectively, 0.84 and 0.75. No floor or ceiling effects were found. According to current international standards, our findings indicate that the EMIC-CSS and the SDS have adequate cultural validity to assess social stigma in leprosy in the Bahasa Indonesia-speaking population of Cirebon District. We believe the scales can be further improved, for instance, by adding, changing and rephrasing certain items. Finally, we provide suggestions for use with other neglected tropical diseases.

The one-year outcome of the randomized controlled T.A.F.F. (Telephone based Adiposity prevention For Families) study is presented. Screening of overweight (BMI-SDS > 90th centile) children 3.5–17.4 years was performed via the German CrescNet database, and candidates were randomized to an intervention group (IG) and control group (CG). The intervention consisted of computer-aided telephone counselling for one year, supported by mailed newsletters. The primary endpoint was change in BMI-SDS; secondary endpoints were eating behavior, physical activity, media consumption, quality of life. Data from 289 families (145 IG (51% females); 144 CG (50% females)) were analyzed (Full Analysis Set: FAS; Per Protocol Set: PPS). Successful intervention was defined as decrease in BMI-SDS ≥ 0.2. In the FAS, 21% of the IG was successful as compared to 16% from the CG (95% CI for this difference: (−4, 14), p = 0.3, mean change in BMI-SDS: −0.02 for IG vs. 0.02 for CG; p = 0.4). According to the PPS, however, the success rate was 35% in the IG compared to 19% in the CG (mean change in BMI-SDS: −0.09 for IG vs. 0.02 for CG; p = 0.03). Scores for eating patterns (p = 0.01), media consumption (p = 0.007), physical activity (p = 9 × 10−9), quality of life (p = 5 × 10−8) decreased with age, independent of group or change in BMI-SDS. We conclude that a telephone-based obesity prevention program suffers from well-known high attrition rates so that its effectiveness could only be shown in those who adhered to completion. The connection between lifestyle and weight status is not simple and requires further research to better understand. PMID:25286167

Childhood obesity is high on the global public health agenda. Although risk factors are well known, the influence of social risk on the therapeutic outcome of lifestyle intervention is poorly examined. This study aims to investigate the influence of migration background, low education, and parental unemployment. 62,147 patients participated in multidimensional lifestyle intervention programs in 179 pediatric obesity centers. Data were collected using standardized software for longitudinal multicenter documentation. 12,305 (19.8%) attended care for 6-24 months, undergoing an intensive therapy period and subsequent follow-ups for up to 3 years. A cumulative social risk score was calculated based on different risk indicators. Migration background, low education, and parental employment significantly influenced the outcome of lifestyle intervention. The observed BMI-SDS reduction was significantly higher in the subgroup with low social risks factors (Δ BMI-SDS -0.19) compared to those presenting moderate (Δ BMI-SDS -0.14) and high social risk (Δ BMI-SDS -0.11). Our data underline the effect of children's social setting on the outcome of multidimensional lifestyle intervention. The presence of a high social risk burden is a negative predictor for successful weight loss. Specific therapeutic programs need to be developed for disadvantaged children and adolescents.

Implant related infection is one of the most feared and devastating complication associated with the use of orthopaedic implant devices. Development of anti-infective surfaces is the main strategy to prevent implant contamination, biofilm formation and implant related osteomyelitis. A second concern in orthopaedics is insufficient osseointegration of uncemented implant devices. Recently, we reported on a macroporous titanium-oxide surface (bioactive TiOB) which increases osseointegration and implant fixation. To combine enhanced osseointegration and antibacterial function, the TiOB surfaces were, in addition, modified with a gentamicin coating. A rat osteomyelitis model with bilateral placement of titanium alloy implants was employed to analyse the prophylactic effect of gentamicin-sodiumdodecylsulfate (SDS) and gentamicin-tannic acid coatings in vivo. 20 rats were randomly assigned to four groups: (A) titanium alloy; PBS inoculum (negative control), (B) titanium alloy, Staphylococcus aureus inoculum (positive control), (C) bioactive TiOB with gentamicin-SDS and (D) bioactive TiOB plus gentamicin-tannic acid coating. Contamination of implants, bacterial load of bone powder and radiographic as well as histological signs of implant-related osteomyelitis were evaluated after four weeks. Gentamicin-SDS coating prevented implant contamination in 10 of 10 tibiae and gentamicin-tannic acid coating in 9 of 10 tibiae (infection prophylaxis rate 100% and 90% of cases, respectively). In Group (D) one implant showed colonisation of bacteria (swab of entry point and roll-out test positive for S. aureus). The interobserver reliability showed no difference in the histologic and radiographic osteomyelitis scores. In both gentamicin coated groups, a significant reduction of the histological osteomyelitis score (geometric mean values: C = 0.111 ± 0.023; D = 0.056 ± 0.006) compared to the positive control group (B: 0.244 ± 0.015; p < 0.05) was observed. The radiographic osteomyelitis scores confirmed these histological findings. Copyright © 2016 Elsevier Ltd. All rights reserved.

Background Transgender women often suffer from transition-related discrimination and loss of social support due to their gender transition, which may pose considerable psychological challenges and may lead to a high prevalence of depression in this population. Increased self-efficacy may combat the adverse effects of gender transition on depression. However, few available studies have investigated the protective effect of self-efficacy on depression among transgender women, and there is a scarcity of research describing the mental health of Chinese transgender women. This study aims to describe the prevalence of depression among Chinese transgender women and to explore the associated factors. Methods A cross-sectional study was conducted in Shenyang, Liaoning Province of China by convenience sampling from January 2014 to July 2014. Two hundred and nine Chinese transgender women were interviewed face-to-face with questionnaires that covered topics including the Zung Self-Rating Depression Scale (SDS), demographic characteristics, transition status, sex partnership, perceived transgender-related discrimination, the Multidimensional Scale of Perceived Social Support (MSPSS) and the adapted General Self-efficacy Scale (GSES). A hierarchical multiple regression analysis was performed to explore the factors associated with SDS scores. Results The prevalence of depression among transgender women was 45.35%. Transgender women with regular partners or casual partners exhibited higher SDS scores than those without regular partners or casual partners. Regression analyses showed that sex partnership explained most (16.6%) of the total variance in depression scores. Self-efficacy was negatively associated with depression. Conclusions Chinese transgender women experienced high levels of depression. Depression was best predicted by whether transgender women had a regular partner or a casual partner rather than transgender-related discrimination and transition status. Moreover, self-efficacy had positive effects on attenuating depression due to gender transition. Therefore, interventions should focus on improving the sense of self-efficacy among these women to enable them to cope with depression and to determine risky sex partnership characteristics, especially for regular and casual partners.

Chronic exposure to job-related stress can lead to depression and BDNF polymorphism may play an important role in this process. The role of the stress × BDNF Val66Met interaction in depression has been studied widely using childhood stress, but few studies have utilized chronic stress in adulthood as a moderator. This study was to examine the chronic stress × BDNF Val66Met interaction in job-related depression in the healthcare workers in a Chinese Han population, which has not been reported yet. Using a cross-sectional design, 243 doctors and nurses were recruited from a general hospital in Beijing, and were assessed for depression with Self-rating Depression Scale (SDS), and the stress using the House and Rizzo's Work Stress Scale. The BDNF Val66Met polymorphism was genotyped. There was a significant positive association between job stress and depressive scores (p < 0.001). No significant main effect of the BDNF Val66Met genotype on depressive symptoms was observed (p > 0.05). A statistically significant interaction between BDNF Val66Met and job stress on depressive symptoms was found (p < 0.05); individuals with Val/Val genotype showed a higher SDS score than Met allele carriers only in the low-stress group, without significant differences in SDS score between the BDNF Val66Met subgroups in medium- or high-stress group. Limitations include cross-sectional study design, the small sample size only in healthcare workers and only one polymorphism in BDNF gene was analyzed. Our results suggest a close relationship between job-related stress and depression, and the interaction of the BDNF Val66Met polymorphism and chronic stress in adulthood may impact the depressive symptoms.

Functional hypothalamic amenorrhea (FHA) related to hypoestrogenism and hormonal status may influence skeletal homeostasis and body composition. The study aimed to evaluate hormones concentrations, body composition and bone strength in FHA cases. Total body scans using DXA method (DPX-L, GE Lunar) were performed in a group of 27 women aged 21.8 years ± 3.9 with FHA related to weight loss. References of healthy control subjects were used to calculate Z-scores (age and gender matched), SD-scores (height and gender matched), and SDs-scores (weight and gender matched). Whole skeleton bone mineral content (TBBMC, g) and density (TBBMD, g/cm(2)), lumbar spine (L2-L4) bone mineral density (SBMD; g/cm(2)), lean body mass (LBM, g) and fat mass (FM, g) were investigated. Relative bone strength index was calculated as the TBBMC/LBM ratio. Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, testosterone, and prolactin (PRL) concentrations were assayed to characterize hormonal profile of FHA cases. Hormonal evaluation in patients with FHA revealed significantly decreased serum concentrations of gonadotropins and estradiol. Serum LH concentrations were 1.47 ± 0.89 mIU/ml, FSH 4.44 ± 1.94 mIU/ml. Estradiol concentrations in serum were 27.08 ± 13.10 pg/ml. As evidenced by Z-scores, FHA cases had decreased SBMD, TBBMD and TBBMC Z-scores of -1.23 ± 0.90 (p < 0.0001), -0.72 ± 0.86 (p < 0.001), and -0.90 ± 1.40 (p < 0.01), respectively. Reduced FM, LBM and FM/LBM ratio Z-scores of -1.80 ± 2.28 (p < 0.001), -0.59 ± 1.49 (p < 0.05) and -0.74 ± 1.55 (p < 0.05), but not TBBMC/LBM Z-score of -0.54 ± 2.14 (ns) were noted in FHA cases compared with healthy control cases. TBBMC, TBBMD, TBBMC/LBM when BH- or BW-matched were normal as evidenced by SD-scores and SDs-scores. SBMD remained reduced when BH-matched (SD-score = -0.40 ± 0.86; p < 0.05) whereas FM and FM/LBM were lower than expected in healthy, both compared to BH- and BW-dependent references. The length of amenorrhea in months negatively correlated with SBMD Z-score (R = -0.39, p < 0.05), and SD-scores for SBMD (R = -0.48), TBBMD (R = -0.43), TBBMC (R = -0.46) (all p < 0.05) and positively with SDs-scores for FM (R = 0.44, p < 0.05). Patients with FHA were characterized by lower concentrations of serum FSH, LH and estradiol concentrations. Moreover, FHA cases had decreased FM and an imbalanced relationship between BW, FM, and LBM. Despite reduced BMD and BMC, bone strength was not significantly affected by FHA.

This study aimed to evaluate the weight loss and hunger motivation effects of an energy-restricted high-protein (HP) diet in overweight and obese children. In total, 95 overweight and obese children attended an 8-week (maximum) program of physical activity, reduced-energy intake, and behavior change education. Children were randomly assigned to one of two isoenergetic diets (standard (SP): 15% protein; HP: 25% protein), based on individually estimated energy requirements. Anthropometry and body composition were assessed at the start and end of the program and appetite and mood ratings completed on the first 3 consecutive weekdays of each week children attended camp. The HP diet had no greater effect on weight loss, body composition, or changes in appetite or mood when compared to the SP diet. Overall, campers lost 5.2 +/- 3.0 kg in body weight and reduced their BMI standard deviation score (sds) by 0.25. Ratings of desire to eat increased significantly over the duration of the intervention, irrespective of diet. This is the third time we have reported an increase in hunger motivation in weight-loss campers and replicates our previous failure to block this with a higher protein diet. Further work is warranted into the management of hunger motivation as a result of negative energy balance.

Epidemiological and animal studies have suggested an effect of the intrauterine milieu upon the development of childhood obesity. This study investigates the relationship between body composition measured by dual energy X-ray absorptiometry expressed as body fat percent, body fat mass index (BFMI), and fat free mass index (FFMI) in obese children and the preceding in utero conditions expressed by birth weight, birth length, and birth weight for gestational age. The study cohort consisted of 776 obese Danish children (median age 11.6 years, range 3.6-17.9) with a mean Body Mass Index Standard Deviation Score (BMI SDS) of 2.86 (range 1.64-5.48) treated in our national referral centre. In a linear general regression model adjusted for age, gender, socioeconomic status, and duration of breastfeeding, we found the body fat percent, FFMI, and BFMI at the time of enrolment in childhood obesity treatment to be significantly correlated with both birth weight and birth weight for gestational age. These results indicate a prenatal influence upon childhood obesity. Although there are currently no sufficient data to suggest any recommendations to pregnant women, it is possible that the prenatal period may be considered as a potential window of opportunity for prevention of childhood overweight and obesity.

Our objective was to evaluate our overall experience in pediatric renal transplantation. Between March 1976 and March 2004, 1,600 live-donor kidney transplantations were carried out in our center; 216 of the patients were 18 years old or younger (mean age 12.9 years). There were 136 male patients and 80 female patients. The commonest causes of end-stage renal disease (ESRD) were renal dysplasia (22%), nephrotic syndrome (20%), hereditary nephritis (16%), and obstructive uropathy (16%). Of the donors, 94% were one-haplotype matched and the rest were identical. Pre-emptive transplantation was performed in 51 (23%) patients. Triple-therapy immunosuppression (prednisone + cyclosporine + azathioprine) was used in 78.2% of transplants. Rejection-free recipients constituted 47.7%. Hypertension (62%) was the commonest complication. A substantial proportion of patients (48%) were short, with height standard deviation score (SDS) less than -1.88. The overall infection rate was high, and the majority (53%) of infections were bacterial. The graft survival at 1 year, 5 years and 10 years were 93.4%, 73.3% and 48.2%, respectively, while the patients' survival at 1, 5 and 10 years were 97.6%, 87.8% and 75.3%, respectively. Despite long-term success results of pediatric renal transplantation in a developing country, there is a risk of significant morbidity.

To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

It is believed that omentin is secreted by stromal cells of adipose tissue and modulates insulin sensitivity. Data from a few studies have shown lower serum omentin in obese children and higher in anorexia nervosa. However, to date, there is lack of research on serum omentin concentrations in adolescent patients in a wide range of body mass index (BMI) and insulin resistance. In this cross-sectional study omentin-1 serum concentrations were evaluated using commercially available ELISA kit in 47 Polish girls with restrictive anorexia nervosa (AN), 50 with simple obesity (OB) and 39 healthy controls (C). The mean serum omentin-1 concentration in girls with AN was statistically significantly higher than that of C and OB girls. Statistically significant (P<0.0001) negative correlations between the serum concentrations of omentin-1 and body weight (r=-0.73), BMI (r=-0.75), standard deviation score for body mass index (BMI-SDS) (r=-0.75), insulin (r=-0.81) and HOMA-IR index (r=-0.82) were seen in the entire examined population. We conclude, that omentin-1 is the nutritional marker reflecting body weight and insulin resistance. Our findings support the hypothesized role of omentin in maintenance of body weight and regulation of appetite and suggest the adaptation of its secretion to body weight and glucose metabolism.

To determine the optimal seating position in a noisy classroom for students with unilateral hearing loss (UHL) without any auditory rehabilitation as compared to normal-hearing adults and student peers. Speech discrimination scores (SDS) for babble noise at distances of 3, 4, 6, 8, and 10 m from a speaker were measured in a simulated classroom measuring 300 m3 (reverberation time = 0.43 s). Students with UHL (n = 25, 10-19 years old), normal-hearing students (n = 25), and normal-hearing adults (n = 25). The SDS for the normal-hearing adults at the 3, 4, 6, 8, and 10 m distances were 90.0±6.4%, 84.7±7.9%, 80.6±10.0%, 75.5±12.6%, and 68.8±13.0%, respectively. Those for the normal-hearing students were 90.1±6.2%, 78.1±9.4%, 66.4±10.7%, 61.8±11.2%, and 60.8±10.9%. Those for the UHL group were 81.7±9.0%, 70.2±12.4%, 62.1±17.2%, 52.4±17.1%, and 48.9±17.9%. The UHL group needed a seating position of 4.35 m to achieve an equivalent mean SDS as those for normal-hearing adults seated at 10 m. Likewise, the UHL group needed to be seated at 6.27 m to have an equivalent SDS as the normal-hearing students seated at 10 m. Students with UHL in noisy classrooms require seating ranging from 4.35 m to no further than 6.27 m away from a teacher to obtain a SDS comparable to normal hearing adults and student peers.

Carotid intima-media thickness (cIMT) and carotid artery distensibility are reliable screening methods for vascular alterations and the assessment of cardiovascular risk in adult and pediatric cohorts. We sought to establish an international reference data set for the childhood and adolescence period and explore the impact of developmental changes in body dimensions and blood pressure (BP) on carotid wall thickness and elasticity. cIMT, the distensibility coefficient, the incremental modulus of elasticity, and the stiffness index β were assessed in 1155 children aged 6 to 18 years and sex-specific reference charts normalized to age or height were constructed from 1051 nonobese and nonhypertensive children. The role of body dimensions, BP, and family history, as well as the association between cIMT and distensibility, was investigated. cIMT increased and distensibility decreased with age, height, body mass index, and BP. A significant sex difference was apparent from the age of 15 years. Age- and height-normalized cIMT and distensibility values differed in children who are short or tall for their age. By stepwise multivariate analysis, standardized systolic BP and body mass index were independently positively associated with cIMT SD scores (SDS). Systolic BP SDS independently predicted all distensibility measures. Distensibility coefficient SDS was negatively and β SDS positively associated with cIMT SDS, whereas incremental modulus of elasticity was independent of cIMT. Morphological and functional aspects of the common carotid artery are particularly influenced by age, body dimensions, and BP. The reference charts established in this study allow to accurately compare vascular phenotypes of children with chronic conditions with those of healthy children.

Severity of illness scores rest on the assumption that patients have normal physiologic values at baseline and that patients with similar severity of illness scores have the same degree of deviation from their usual state. Prior studies have reported differences in baseline physiology, including laboratory markers, between obese and normal weight individuals, but these differences have not been analyzed in the ICU. We compared deviation from baseline of pertinent ICU laboratory test results between obese and normal weight patients, adjusted for the severity of illness. Retrospective cohort study in a large ICU database. Tertiary teaching hospital. Obese and normal weight patients who had laboratory results documented between 3 days and 1 year prior to hospital admission. None. Seven hundred sixty-nine normal weight patients were compared with 1,258 obese patients. After adjusting for the severity of illness score, age, comorbidity index, baseline laboratory result, and ICU type, the following deviations were found to be statistically significant: WBC 0.80 (95% CI, 0.27-1.33) × 10/L; p = 0.003; log (blood urea nitrogen) 0.01 (95% CI, 0.00-0.02); p = 0.014; log (creatinine) 0.03 (95% CI, 0.02-0.05), p < 0.001; with all deviations higher in obese patients. A logistic regression analysis suggested that after adjusting for age and severity of illness at least one of these deviations had a statistically significant effect on hospital mortality (p = 0.009). Among patients with the same severity of illness score, we detected clinically small but significant deviations in WBC, creatinine, and blood urea nitrogen from baseline in obese compared with normal weight patients. These small deviations are likely to be increasingly important as bigger data are analyzed in increasingly precise ways. Recognition of the extent to which all critically ill patients may deviate from their own baseline may improve the objectivity, precision, and generalizability of ICU mortality prediction and severity adjustment models.

Development and operation of a quality assurance system for deviations from standard operating procedures in a clinical cell therapy laboratory.

Errors and accidents, or deviations from standard operating procedures, other policy, or regulations must be documented and reviewed, with corrective actions taken to assure quality performance in a cellular therapy laboratory. Though expectations and guidance for deviation management exist, a description of the framework for the development of such a program is lacking in the literature. Here we describe our deviation management program, which uses a Microsoft Access database and Microsoft Excel to analyze deviations and notable events, facilitating quality assurance (QA) functions and ongoing process improvement. Data is stored in a Microsoft Access database with an assignment to one of six deviation type categories. Deviation events are evaluated for potential impact on patient and product, and impact scores for each are determined using a 0- 4 grading scale. An immediate investigation occurs, and corrective actions are taken to prevent future similar events from taking place. Additionally, deviation data is collectively analyzed on a quarterly basis using Microsoft Excel, to identify recurring events or developing trends. Between January 1, 2001 and December 31, 2001 over 2500 products were processed at our laboratory. During this time period, 335 deviations and notable events occurred, affecting 385 products and/or patients. Deviations within the 'technical error' category were most common (37%). Thirteen percent of deviations had a patient and/or a product impact score > or = 2, a score indicating, at a minimum, potentially affected patient outcome or moderate effect upon product quality. Real-time analysis and quarterly review of deviations using our deviation management program allows for identification and correction of deviations. Monitoring of deviation trends allows for process improvement and overall successful functioning of the QA program in the cell therapy laboratory. Our deviation management program could serve as a model for other laboratories in need of such a program.

A better norm-referenced grading using the standard deviation criterion.

PubMed

Chan, Wing-shing

2014-01-01

The commonly used norm-referenced grading assigns grades to rank-ordered students in fixed percentiles. It has the disadvantage of ignoring the actual distance of scores among students. A simple norm-referenced grading via standard deviation is suggested for routine educational grading. The number of standard deviation of a student's score from the class mean was used as the common yardstick to measure achievement level. Cumulative probability of a normal distribution was referenced to help decide the amount of students included within a grade. RESULTS of the foremost 12 students from a medical examination were used for illustrating this grading method. Grading by standard deviation seemed to produce better cutoffs in allocating an appropriate grade to students more according to their differential achievements and had less chance in creating arbitrary cutoffs in between two similarly scored students than grading by fixed percentile. Grading by standard deviation has more advantages and is more flexible than grading by fixed percentile for norm-referenced grading.

This prospective, open-label, non-comparative, multicentre, long-term phase IV study is examining the efficacy and safety of somatropin [recombinant human growth hormone (rhGH)] in short children born small for gestational age (SGA) and its impact on the incidence of diabetes. This report is the first interim analysis of patients who have completed 1 year of treatment. A total of 278 pre-pubertal patients were enrolled. Key eligibility criteria included height standard deviation score (HSDS) <-2.5; parental adjusted SDS <-1; birth weight and/or length <-2 SD and failure to show catch-up growth by ≥4 years of age. Patients were treated with rhGH 0.035 mg/kg/day. The primary objective was to evaluate the long-term effect of rhGH on carbohydrate metabolism [including fasting glucose, stimulated glucose (2-h oral glucose tolerance test, OGTT) and glycated haemoglobin (HbA1c)]. Secondary objectives included evaluation of height parameters [body height, HSDS, height velocity (HV), HVSDS]; insulin-like growth factor 1 (IGF-I) and insulin-like growth factor-binding protein 3 (IGFBP-3) serum levels during treatment; and incidence and severity of adverse events (AEs). None of the children developed diabetes mellitus within the first year of treatment. Mean levels of fasting glucose, HbA1c and 2-h OGTT values remained stable during the study period. Treatment with rhGH was effective, as documented by all height parameters. Mean HSDS improved from -3.39 at baseline to -2.57 at Year 1. Mean HV increased markedly from 4.25 cm/year at baseline to 8.99 cm/year during the first year. Similarly, mean peak-centred HVSDS increased from -2.13 at baseline to +4.16 at Year 1. Mean IGF-I SDS and IGFBP-3 SDS also increased within the first year (by +1.80 and +0.41, respectively). 13 patients (4.7%) did not respond adequately to treatment (HVSDS <1); they were withdrawn from the study. In total, 192 children (69.3%) experienced treatment-emergent AEs; most (98.7%) were mild-to-moderate, and the majority (96.5%) were unrelated to study treatment. This interim analysis shows that short children born SGA can be effectively and safely treated with rhGH and that rhGH treatment has no major impact on carbohydrate metabolism after the first year of treatment.

OBJECTIVES: To characterize the voice quality of individuals with dysphonia and to investigate possible correlations between the degree of voice deviation (D) and scores on the Dysphonia Risk Screening Protocol-General (DRSP), the Voice-Related Quality of Life (V-RQOL) measure and the Voice Handicap Index, short version (VHI-10). METHODS: The sample included 200 individuals with dysphonia. Following laryngoscopy, the participants completed the DRSP, the V-RQOL measure, and the VHI-10; subsequently, voice samples were recorded for auditory-perceptual and acoustic analyses. The correlation between the score for each questionnaire and the overall degree of vocal deviation was analyzed, as was the correlation among the scores for the three questionnaires. RESULTS: Most of the participants (62%) were female, and the mean age of the sample was 49 years. The most common laryngeal diagnosis was organic dysphonia (79.5%). The mean D was 59.54, and the predominance of roughness had a mean of 54.74. All the participants exhibited at least one abnormal acoustic aspect. The mean questionnaire scores were DRSP, 44.7; V-RQOL, 57.1; and VHI-10, 16. An inverse correlation was found between the V-RQOL score and D; however, a positive correlation was found between both the VHI-10 and DRSP scores and D. CONCLUSION: A predominance of adult women, organic dysphonia, moderate voice deviation, high dysphonia risk, and low to moderate quality of life impact characterized our sample. There were correlations between the scores of each of the three questionnaires and the degree of voice deviation. It should be noted that the DRSP monitored the degree of dysphonia severity, which reinforces its applicability for patients with different laryngeal diagnoses. PMID:29538494

The aim of this study was to clarify the differences in thallium-201-chloride (thallium-201) myocardial perfusion imaging (MPI) scans evaluated by conventional anger-type single-photon emission computed tomography (conventional SPECT) versus cadmium-zinc-telluride SPECT (CZT SPECT) imaging in normal databases for different ethnic groups. MPI scans from 81 consecutive Japanese patients were examined using conventional SPECT and CZT SPECT and analyzed with the pre-installed quantitative perfusion SPECT (QPS) software. We compared the summed stress score (SSS), summed rest score (SRS), and summed difference score (SDS) for the two SPECT devices. For a normal MPI reference, we usually use Japanese databases for MPI created by the Japanese Society of Nuclear Medicine, which can be used with conventional SPECT but not with CZT SPECT. In this study, we used new Japanese normal databases constructed in our institution to compare conventional and CZT SPECT. Compared with conventional SPECT, CZT SPECT showed lower SSS (p < 0.001), SRS (p = 0.001), and SDS (p = 0.189) using the pre-installed SPECT database. In contrast, CZT SPECT showed no significant difference from conventional SPECT in QPS analysis using the normal databases from our institution. Myocardial perfusion analyses by CZT SPECT should be evaluated using normal databases based on the ethnic group being evaluated.

To characterize the endocrine phenotype of patients with Shwachman-Diamond syndrome (SDS). Clinically indicated endocrine screening data from 43 patients with SDS or SDS-like presentation were analyzed according to sex, age, and genetic testing. In addition to 25 patients with biallelic Shwachman-Bodian-Diamond syndrome (SBDS) gene mutations, we evaluated 18 patients with cytopenias who were receiving pancreatic enzyme replacement but were without SBDS mutation. We performed a retrospective review of growth records and clinically indicated endocrine evaluations. Of patients with SBDS mutations, 2 had low stimulated growth hormone levels, 2 had mildly elevated thyrotropin levels, 5 had abnormal glucose levels, and 1 had an elevated follicle-stimulating hormone level (post transplantation). In contrast, 1 patient without SBDS mutations had postprandial hyperglycemia and 3 had mildly low free thyroxine levels without short stature. Endocrine abnormalities were identified in 19% of short patients and 26% of the whole group. Of patients with SBDS mutations, 56% had a height expressed in SD units from the mean for age and sex of <-1.8, in contrast to only 12% of patients without SBDS mutations (38% of the whole group). Body mass index z score was significantly greater in the group with SBDS mutations (P<.001). Although short stature was more common in patients with SBDS mutations, no consistent endocrine phenotype was observed in patients with SDS regardless of genetic testing. Copyright © 2013 Mosby, Inc.

Previous studies have shown that heart rate variability (HRV) measurement is useful in investigating the pathophysiology of various psychiatric disorders. The present study further examined its usefulness in evaluating the mental health of normal subjects with respect to anxiety and depressiveness. Heart rate (HR) and HRV were measured tonometrically at the wrist in 43 normal subjects not only in the resting condition but also during a task (random number generation) to assess the responsiveness. For HRV measurement, high-frequency (HF; 0.15-0.4 Hz) and low-frequency (LF; 0.04-0.15 Hz) components of HRV were obtained using MemCalc, a time series analysis technique that combines a non-linear least square method with maximum entropy method. For psychological evaluation of anxiety and depressiveness, two self-report questionnaires were used: State-Trait Anxiety Inventory (STAI) and Self-Rating Depression Scale (SDS). No significant relation was observed between HR and HRV indices, and the psychological scores both in the resting and task conditions. By task application, HF decreased, and LF/HF and HR increased, and significant correlation with psychological scores was found in the responsiveness to task measured by the ratio of HRV and HR indices during the task to that at rest (task/rest ratio). A positive relationship was found between task/rest ratio for HF, and STAI and SDS scores. Task/rest ratio of HR was negatively correlated with STAI-state score. Decreased HRV response to task application is related to anxiety and depressiveness. Decreased autonomic responsiveness could serve as a sign of psychological dysfunction.

The setup errors and organ motion errors pertaining to clinical target volume (CTV) have been considered as two major causes of uncertainties in the determination of the CTV-to-planning target volume (PTV) margins for prostate cancer radiation treatment planning. We based our study on the assumption that interfractional target shape variations are not negligible as another source of uncertainty for the determination of precise CTV-to-PTV margins. Thus, we investigated the interfractional shape variations of CTVs based on a point distribution model (PDM) for prostate cancer radiation therapy. To quantitate the shape variations of CTVs, the PDM was applied for the contours of 4 types of CTV regions (low-risk, intermediate- risk, high-risk CTVs, and prostate plus entire seminal vesicles), which were delineated by considering prostate cancer risk groups on planning computed tomography (CT) and cone beam CT (CBCT) images of 73 fractions of 10 patients. The standard deviations (SDs) of the interfractional random errors for shape variations were obtained from covariance matrices based on the PDMs, which were generated from vertices of triangulated CTV surfaces. The correspondences between CTV surface vertices were determined based on a thin-plate spline robust point matching algorithm. The systematic error for shape variations was defined as the average deviation between surfaces of an average CTV and planning CTVs, and the random error as the average deviation of CTV surface vertices for fractions from an average CTV surface. The means of the SDs of the systematic errors for the four types of CTVs ranged from 1.0 to 2.0 mm along the anterior direction, 1.2 to 2.6 mm along the posterior direction, 1.0 to 2.5 mm along the superior direction, 0.9 to 1.9 mm along the inferior direction, 0.9 to 2.6 mm along the right direction, and 1.0 to 3.0 mm along the left direction. Concerning the random errors, the means of the SDs ranged from 0.9 to 1.2 mm along the anterior direction, 1.0 to 1.4 mm along the posterior direction, 0.9 to 1.3 mm along the superior direction, 0.8 to 1.0 mm along the inferior direction, 0.8 to 0.9 mm along the right direction, and 0.8 to 1.0 mm along the left direction. Since the shape variations were not negligible for intermediate and high-risk CTVs, they should be taken into account for the determination of the CTV-to-PTV margins in radiation treatment planning of prostate cancer. © 2017 American Association of Physicists in Medicine.

Both the myocardial perfusion pattern and myocardial blood flow (MBF) are used to assess patients with suspected coronary artery disease (CAD). The aim of this study was to compare the perfusion pattern (using the summed difference score [SDS]) to MBF in a consecutive group of patients undergoing PET/CT with 13 N-ammonia ( 13 NH 3 ). 47 consecutive patients, aged 65 ± 12 years (42 men) with known or suspected CAD, underwent vasodilator stress/rest PET/CT with 13 NH 3 for clinical indications. The SDS was determined by a commercially available software based on a 17-segment model. MBF was measured at rest and during hyperemia by dynamic acquisition and single-compartment model analysis. From the rest and stress MBF, the absolute difference (stress-rest) in myocardial blood flow defined as difference in myocardial blood flow (DMBF) was derived. There were no significant differences between patients with no ischemia (SDS ≤ 1) and those with ischemia (SDS > 1) in CFR (2.84 ± 0.73 vs 2.63 ± 0.89, P = NS) and DMBF (1.34 ± 0.45 vs 1.24 ± 0.53 mL·minute -1 ·g -1 , P = NS). There were however significant regional differences (141 different vascular territories in 47 patients) between these two groups (CFR: 2.84 ± 0.95 vs 2.16 ± 0.57, P < .001 and DMBF: 1.39 ± 0.6 vs 0.87 ± 0.39, P < .0001). The correlation between regional CFR and regional DMBF with SDS was significant (y = 2.7145e -0.059x R = 0.358 and y = 1.2769e -0.119x R = 0.44) CONCLUSION: The SDS is the difference between two measurements (stress-rest) and it correlates better with regional DMBF, which is another measurement that reflects the difference between stress and rest. The correlation is better on regional than global basis.

Tramadol-acetaminophen tablets are currently used to treat pain, including that of degenerative lumbar disease. Although there are many reports on tramadol-acetaminophen tablets, treatment outcomes in low back pain (LBP) patients with depression remain uncertain. This study investigated the outcomes of LBP patients with depression treated with tramadol-acetaminophen tablets. Of 95 patients with chronic LBP, 70 (26 men, 44 women; mean age 64 years) who were judged as having depression by the Self-Rating Depression Scale (SDS) were included in this study. In this trial, patients received one of two randomly assigned 8-week treatment regimes: tramadol-acetaminophen (Tramadol group, n = 35) and non-steroidal anti-inflammatory drugs (NSAIDs) (NSAID group, n = 35). In addition to completing self-report questionnaires, patients provided demographic and clinical information. All patients were assessed using a Numerical Rating Scale (NRS), Oswestry Disability Index (ODI), Pain Disability Assessment Scale (PDAS), Hospital Anxiety and Depression Scale (HADS), SDS, and Pain Catastrophizing Scale (PCS). After 8 weeks' treatment, the NRS and SDS scores were lower in the Tramadol group than in the NSAID group (p < 0.05). There were no significant differences in the ODI, PDAS, and PCS scores between the groups (p = 0.47, 0.09, 0.47). Although there was no difference in the anxiety component of the HADS between the groups (p = 0.36), the depression component was lower in the Tramadol group than in the NSAID group (p < 0.05). There was no significant difference between groups in the percentage of patients with treatment-associated adverse events. This investigation found that tramadol-acetaminophen is effective for reducing LBP and provided a prophylactic antidepressant effect in chronic LBP patients with depression.

Results in studies concerning cortical changes in idiopathic sudden sensorineural hearing loss (ISSNHL) are not homogeneous, in particular due to the different neuroimaging techniques implemented and the diverse stages of ISSNHL studied. Considering the recent advances in state-of-the-art positron emission tomography (PET) cameras, the aim of this study was to gain more insight into the neuroanatomical differences associated with the earliest stages of unilateral ISSNHL and clinical-perceptual performance changes. After an audiological examination including the mean auditory threshold (mean AT), mean speech discrimination score (mean SDS) and Tinnitus Handicap Inventory (THI), 14 right-handed ISSNHL patients underwent brain [ 18 F]fluorodeoxyglucose (FDG)-PET within 72 h of the onset of symptoms. When compared to an homogeneous group of 35 healthy subjects by means of statistical parametric mapping, a relative increase in FDG uptake was found in the right superior and medial frontal gyrus as well as in the right anterior cingulate cortex in ISSNHL patients. Conversely, the same group showed a significant relative decrease in FDG uptake in the right middle temporal, precentral and postcentral gyrus as well as in the left posterior cingulate cortex, left lingual, superior, middle temporal and middle frontal gyrus and in the left insula. Regression analysis showed a positive correlation between mean THI and glucose consumption in the right anterior cingulate cortex and a positive correlation between mean SDS and glucose consumption in the left precentral gyrus. The relative changes in FDG uptake found in these brain regions and the positive correlation with mean SDS and THI scores in ISSNHL could possibly highlight new aspects of cerebral rearrangement, contributing to further explain changes in those functions that support speech recognition during the sudden impairment of unilateral auditory input.

Numerous studies have confirmed that brain tumor patients and their family members frequently exhibit negative emotional reactions, such as anxiety and depression, during diagnosis and treatment of the disease. Family members experience increasing pressure as the year of survival of patient progress. The aim of this study was to investigate the effects of the continued psychological care (CPC) toward the brain tumor patients and their family members' emotions. The asynchronous clinical control trial was performed, and 162 brain tumor patients and their family members were divided into the control group and the intervention group. The control group was only performed the telephone follow-up toward the patients. Beside this way, the intervention group was performed the CPC toward the patients and their family member. The self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were used to measure the negative emotions of the patients and their family members, and the patients' treatment compliance and the incidence of seizures were compared. The SAS and SDS scores of the intervention group on the 14 days, 28 days and 3 months of the CPC were significantly lower than the control group (P < 0.05); the SAS and SDS scores of the intervention group after the intervention were significantly lower than those at the discharging (P < 0.05), the treatment compliance of the intervention group was significantly higher than the control group (P < 0.05), and the seizure incidence of the intervention group was significantly lower than the control group (P < 0.05). The CPC could effectively reduce the anxiety and depression among the brain tumor patients and their family members.

Atomoxetine treatment is associated with improvements in functional outcomes in patients with attention-deficit/hyperactivity disorder (ADHD), although relationships between improvements in these outcomes and reductions in ADHD symptoms have not been comprehensively investigated in adults. The aim of this study was to assess relationships between functional outcomes and ADHD symptoms (primary objective), and to assess time courses of changes in functional outcomes from baseline to weeks 10 and 24 (secondary objective). We analyzed data pooled from seven Eli Lilly-sponsored placebo-controlled trials of atomoxetine in adults with ADHD that had Conners' Adult ADHD Rating Scales-Investigator Rated: Screening Version (CAARS-Inv:SV) total scores and functional outcome data at baseline and at week 10. Two trials also had these data at week 24. Patients were included in these pooled analyses if they had a CAARS-Inv:SV total score at baseline and at one or more post-baseline visits at weeks 10 or 24, or had post-baseline scores that would allow missing scores at weeks 10 or 24 to be imputed. To address the primary objective, changes in functional outcomes during treatment with atomoxetine versus placebo were assessed using last observation carried forward (LOCF) analysis of covariance (ANCOVA) and mixed-effects model repeated measures (MMRM) analysis, and correlations between score changes in CAARS-Inv:SV total and functional outcomes were assessed using Spearman's rank correlation coefficient (r) at weeks 10 and 24. The secondary objective was addressed using MMRM. At baseline, patients generally had moderately severe or worse ADHD symptoms (based on CAARS-Inv:SV total scores) and impaired functional outcomes (based on Adult ADHD Quality-of-Life [AAQoL], Behavior Rating Inventory of Executive Function-Adult Version [BRIEF-A], Sheehan Disability Scale [SDS], and 36-item Short-Form Health Survey [SF-36] scores). These baseline characteristics were comparable in the atomoxetine and placebo groups. For atomoxetine versus placebo, statistically significant improvements were detected in AAQoL total and subscores at weeks 10 and 24, and in BRIEF-A Self-Report scores at week 10, but not in BRIEF-A Informant Report or SDS scores at week 10 (no BRIEF-A or SDS data were available at week 24), and not in SF-36 at weeks 10 or 24. All functional improvements were gradual. During treatment with atomoxetine, there were moderate correlations between reductions in CAARS-Inv:SV total scores and increases in AAQoL total and subscores at weeks 10 and 24 (r range -0.58 to -0.39; n = 394-545), and also with reductions in BRIEF-A Self-Report at week 10 (r = 0.49; n = 256). With placebo, moderate correlations were also found between reductions in CAARS-Inv:SV total scores and increases in AAQoL total and subscores at weeks 10 and 24 (r range -0.56 to -0.28; n = 321-542), and with reductions in BRIEF-A Self-Report at week 10 (r = 0.49; n = 271). However, correlations between changes in CAARS-Inv:SV and BRIEF-A Informant at week 10 were low for atomoxetine-treated patients (r = 0.25; n = 65), moderate with placebo (r = 0.42; n = 72), and there were low/no correlations between changes in CAARS-Inv:SV and functional outcome rating scales that are not specific to ADHD; that is, for atomoxetine-treated patients, SDS total r = 0.19 (n = 32 at week 10) and SF-36 r range - 0.20 to -0.01 (n = 51 at week 10, n = 183 at week 24). Atomoxetine-treated adult patients experienced improvements in functional outcomes (AAQoL and BRIEF-A Self-Report) that correlated with reductions in ADHD symptoms. Although atomoxetine improved both the ADHD symptoms and functional outcomes, the correlation between symptoms and functional outcomes was low to moderate, suggesting that they measure overlapping but different aspects of the disorder. Hence, clinicians should assess not just ADHD symptoms, but also the functional impairments.

Fetal smoke exposure may influence growth and body composition later in life. We examined the associations of maternal and paternal smoking during pregnancy with total and abdominal fat distribution in school-age children. We performed a population-based prospective cohort study among 5243 children followed from early pregnancy onward in the Netherlands. Information about parental smoking was obtained by questionnaires during pregnancy. At the median age of 6.0 years (90% range: 5.7-7.4), we measured anthropometrics, total fat and android/gynoid fat ratio by dual-energy X-ray absorptiometry, and preperitoneal and subcutaneous abdominal fat were measured by ultrasound. The associations of maternal smoking during pregnancy were only present among girls (P-value for sex interaction<0.05). Compared with girls from mothers who did not smoke during pregnancy, those from mothers who smoked during the first trimester only had a higher android/gynoid fat ratio (difference 0.23 (95% confidence interval (CI): 0.09-0.37) s.d. scores (SDS). Girls from mothers who continued smoking throughout pregnancy had a higher body mass index (difference: 0.24 (95% CI: 0.14-0.35) SDS), total fat mass (difference: 0.23 (95% CI: 0.14-0.33) SDS), android/gynoid fat ratio (difference: 0.34 (95% CI: 0.22-0.46) SDS), subcutaneous abdominal fat (difference: 0.22 (95% CI: 0.11-0.33) SDS) and preperitoneal abdominal fat (difference: 0.20 (95% CI: 0.08-0.31) SDS). Similar associations with body fat distribution outcomes were observed for paternal smoking during pregnancy. Both continued maternal and paternal smoking during pregnancy may be associated with an increased risk of childhood overweight. The corresponding odds ratios were 1.19 (95% CI: 0.98-1.46) and 1.32 (1.10-1.58), respectively. Maternal and paternal smoking during pregnancy are associated with an adverse body and abdominal fat distribution and increased risk of overweight in children. Similar effects of maternal and paternal smoking suggest that direct intrauterine mechanisms and common family-based lifestyle-related factors explain the associations.

Background Stigma plays in an important role in the lives of persons affected by neglected tropical diseases, and assessment of stigma is important to document this. The aim of this study is to test the cross-cultural validity of the Community Stigma Scale (EMIC-CSS) and the Social Distance Scale (SDS) in the field of leprosy in Cirebon District, Indonesia. Methodology/principle findings Cultural equivalence was tested by assessing the conceptual, item, semantic, operational and measurement equivalence of these instruments. A qualitative exploratory study was conducted to increase our understanding of the concept of stigma in Cirebon District. A process of translation, discussions, trainings and a pilot study followed. A sample of 259 community members was selected through convenience sampling and 67 repeated measures were obtained to assess the psychometric measurement properties. The aspects and items in the SDS and EMIC-CSS seem equally relevant and important in the target culture. The response scales were adapted to ensure that meaning is transferred accurately and no changes to the scale format (e.g. lay out, statements or questions) of both scales were made. A positive correlation was found between the EMIC-CSS and the SDS total scores (r = 0.41). Cronbach's alphas of 0.83 and 0.87 were found for the EMIC-CSS and SDS. The exploratory factor analysis indicated for both scales an adequate fit as unidimensional scale. A standard error of measurement of 2.38 was found in the EMIC-CSS and of 1.78 in the SDS. The test-retest reliability coefficient was respectively, 0.84 and 0.75. No floor or ceiling effects were found. Conclusions/significance According to current international standards, our findings indicate that the EMIC-CSS and the SDS have adequate cultural validity to assess social stigma in leprosy in the Bahasa Indonesia-speaking population of Cirebon District. We believe the scales can be further improved, for instance, by adding, changing and rephrasing certain items. Finally, we provide suggestions for use with other neglected tropical diseases.

Alprazolam is prescribed for the treatment of anxiety and panic disorder. Most users are presumably involved in daily activities such as driving. However, the effects of alprazolam on driving ability have never been investigated. This study was conducted to determine the effects of alprazolam (1 mg) on driving ability, memory and psychomotor performance. Twenty healthy volunteers participated in a randomized, double-blind, placebo-controlled crossover study. One hour after oral administration, subjects performed a standardized driving test on a primary highway during normal traffic. They were instructed to drive with a constant speed (90 km/h) while maintaining a steady lateral position within the right traffic lane. Primary performance measures were the Standard Deviation of Lateral Position (SDLP) and the Standard Deviation of Speed (SDS). After the driving test, subjective driving quality, mental effort, and mental activation during driving were assessed. A laboratory test battery was performed 2.5 h after treatment administration, comprising the Sternberg Memory Scanning Test, a Continuous Tracking Test, and a Divided Attention Test. Relative to placebo, alprazolam caused serious driving impairment, as expressed by a significantly increased SDLP (F(1,19) = 97.3, p <.0001) and SDS (F(1,19) = 30.4, p <.0001). This was confirmed by subjective assessments showing significantly impaired driving quality (F(1,19) = 16.4, p <.001), decreased alertness (F(1,19) = 43.4, p <.0001), decreased mental activation (F(1,19) = 5.7, p <.03) and increased mental effort during driving (F(1,19) = 26.4, p <.0001). Furthermore, alprazolam significantly impaired performance on the laboratory tests. In conclusion, alprazolam users must be warned not to drive an automobile or operate potentially dangerous machinery.

Fisher information and Cramér-Rao lower bound for experimental design in parallel imaging.

The Cramér-Rao lower bound (CRLB) is widely used in the design of magnetic resonance (MR) experiments for parameter estimation. Previous work has considered only Gaussian or Rician noise distributions in this calculation. However, the noise distribution for multi-coil acquisitions, such as in parallel imaging, obeys the noncentral χ-distribution under many circumstances. The purpose of this paper is to present the CRLB calculation for parameter estimation from multi-coil acquisitions. We perform explicit calculations of Fisher matrix elements and the associated CRLB for noise distributions following the noncentral χ-distribution. The special case of diffusion kurtosis is examined as an important example. For comparison with analytic results, Monte Carlo (MC) simulations were conducted to evaluate experimental minimum standard deviations (SDs) in the estimation of diffusion kurtosis model parameters. Results were obtained for a range of signal-to-noise ratios (SNRs), and for both the conventional case of Gaussian noise distribution and noncentral χ-distribution with different numbers of coils, m. At low-to-moderate SNR, the noncentral χ-distribution deviates substantially from the Gaussian distribution. Our results indicate that this departure is more pronounced for larger values of m. As expected, the minimum SDs (i.e., CRLB) in derived diffusion kurtosis model parameters assuming a noncentral χ-distribution provided a closer match to the MC simulations as compared to the Gaussian results. Estimates of minimum variance for parameter estimation and experimental design provided by the CRLB must account for the noncentral χ-distribution of noise in multi-coil acquisitions, especially in the low-to-moderate SNR regime.

This study determined if robotic-arm assisted total knee arthroplasty (RATKA) allows for more accurate and precise bone cuts and component position to plan compared with manual total knee arthroplasty (MTKA). Specifically, we assessed the following: (1) final bone cuts, (2) final component position, and (3) a potential learning curve for RATKA. On six cadaver specimens (12 knees), a MTKA and RATKA were performed on the left and right knees, respectively. Bone-cut and final-component positioning errors relative to preoperative plans were compared. Median errors and standard deviations (SDs) in the sagittal, coronal, and axial planes were compared. Median values of the absolute deviation from plan defined the accuracy to plan. SDs described the precision to plan. RATKA bone cuts were as or more accurate to plan based on nominal median values in 11 out of 12 measurements. RATKA bone cuts were more precise to plan in 8 out of 12 measurements ( p  ≤ 0.05). RATKA final component positions were as or more accurate to plan based on median values in five out of five measurements. RATKA final component positions were more precise to plan in four out of five measurements ( p  ≤ 0.05). Stacked error results from all cuts and implant positions for each specimen in procedural order showed that RATKA error was less than MTKA error. Although this study analyzed a small number of cadaver specimens, there were clear differences that separated these two groups. When compared with MTKA, RATKA demonstrated more accurate and precise bone cuts and implant positioning to plan. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

SHOX mutations causing haploinsufficiency were reported in Leri-Weill dyschondrosteosis (LWD), which is characterized by mesomelic short stature and Madelung deformity of the wrists. The aim of this study was to determine the prevalence of SHOX mutations in LWD and to investigate the degree of growth failure in relation to mutation, sex, age of menarche, and wrist deformity. We studied 20 families with 24 affected children (18 females) and nine affected parents (seven females). All patients presented with bilateral Madelung deformity and shortening of the limbs. Height, sitting height, parental height, birth length, age of menarche, and presence of minor abnormalities were recorded. The degree of Madelung deformity was estimated by analysis of left hand radiographs. Microsatellite typing of the SHOX locus was used for detection of SHOX deletions and PCR direct sequencing for the detection of SHOX point mutations. In 14 of 20 families (70%), SHOX mutations were detected, with seven deletions (four de novo) and seven point mutations (one de novo). The latter included five missense mutations of the SHOX homeodomain, one nonsense mutation (E102X) truncating the whole homeodomain, and one point mutation (X293R) causing a C-terminal elongation of SHOX. Median age of the affected children was 13.4 yr (range, 6.1-18.3), mean height sd score (SDS) (sd in parentheses) was -2.85 (1.04), and mean sitting height/height ratio SDS was +3.06 (1.09). Mean birth length SDS was -0.59 (1.26). Growth failure occurred before school age. Height change during a median follow-up of 7.4 yr (range, 2.3-11.3) was insignificant with a mean change in height SDS of -0.10 (0.52). Mean height SDS of affected parents was -2.70 (0.85) vs. -0.91 (1.10) in unaffected parents. Height loss due to LWD was estimated calculating delta height defined by actual height SDS minus target height SDS of the unaffected parent(s). In the children, mean delta height SDS was -2.16 (1.06), the loss being greater in girls at -2.30 (1.02) than in boys at -1.72 (1.09) (P = 0.32). In patients with SHOX deletions, it was -2.14 (1.15) vs. -1.67 (0.73) for the SHOX point mutation group (P = 0.38). Mean delta height SDS was -2.26 (0.68) for the girls with early menarche (<12 yr) vs. -2.08 (0.91) for the other postmenarcheal girls (P = 0.72). Height loss in patients with radiologically severe wrist deformities in comparison with those having milder radiological signs was -2.81 (1.01) vs. -1.70 (1.04) (P = 0.03). GH treatment in five children during a median duration of 3.4 yr (range, 1.5-9.8 yr) with a median dosage of 0.23 mg/kg.wk (range, 0.14-0.25) resulted in a mean height SDS gain of +0.82 (0.34). In conclusion, SHOX defects were the main cause of LWD. Growth failure occurred during the first years of life with a mean height loss of 2.16 SDS whereas pubertal growth may only be mildly or not affected. Children with a severe degree of wrist deformity were significantly shorter than those with mild deformities. No statistically significant effects of type of mutation, age of menarche, or sex on height were observed. The effect of GH therapy varied between individuals and needs to be examined in controlled studies.

Hypothalamic obesity (HyOb) is a common complication of childhood hypothalamic tumours. Patients with HyOb probably have a higher mortality rate than those with other types of obesity due in many cases to obstructive sleep apnoea/hypoventilation. To identify predictive factors for mortality caused by HyOb in children. Twenty children with HyOb secondary to hypothalamic tumours that were followed-up for ≥3 years and aged <15 years at diagnosis, and received supraphysiological glucocorticoid treatment for ≤1 month. Mean age at diagnosis was 6.36 ± 3.60 years. Mean body mass index (BMI) Standard deviation of the samples (SDS) increased from 0.77 ± 1.26 to 2.66 ± 1.45 during the first 6 months, but slowed from month 6-12 (2.73 ± 1.35). ΔBMI SDS at 0-6 months was significantly higher in patients aged <6 years at diagnosis than in those aged >6 years at diagnosis (3.71 ± 1.96 vs. 0.83 ± 0.73, P < 0.001). Maximum BMI SDS was also significantly higher in the younger group (3.88 ± 1.39 vs. 2.79 ± 0.64, P < 0.05). In all, four patients died and the mortality rate was significantly higher in the patients with a further increase in BMI SDS > 1 SDS after 6 months of therapy (RR: 8.4, P < 0.05). Both overall mortality and obesity-related mortality rates were higher in the patients aged <6 years at diagnosis (4.5-fold, 7.2-fold higher, respectively, P > 0.05). The mortality rate was also 3.7-fold higher in the patients with a maximum BMI SDS ≥ 3 at any time during the first 3 years after therapy(P > 0.05). An increase in BMI SDS after 6 months of therapy was observed to be a risk factor for mortality caused by HyOb. In addition, age <6 years at diagnosis and a maximum BMI SDS ≥ 3 were associated with a higher mortality rate, indicating that earlier and more aggressive treatment of obesity is required. © 2015 World Obesity.

To describe the final height and height-gain in relation to target height, in children with type 1 diabetes mellitus, and analyse their relationship to different variables. Retrospective analysis of the growth data of 52 children (27 girls) diagnosed with type 1 diabetes mellitus before 14 years old, and followed up until their final height was attained. final height, target height, illness duration, glycated haemoglobin (HbA1c), insulin dose, BMI, and other autoimmune diseases. The height SDS (standard deviation scale) at diagnosis was slightly higher (0.734 in boys and 0.563 in girls). During the development of the disease, a growth reduction was seen, which was significantly higher in boys of prepubertal age (p = 0.016). The mean final height attained was 173.14 +/- 5.28 cm in boys and 161.9 +/- 6.97 cm in girls. Height gain was 1.56 +/- 3.66 in boys (SDS = -0.034) and 2.26 +/- 6.13 in girls (SDS = 0.385). The only variable significantly related to height gain was mean glycated-haemoglobin (growth reduction of 2 cm for every increment of 1% in mean glycated-haemoglobin). At onset, diabetic children were slightly taller than the general population. A growth reduction was shown as the disease developed, significantly higher in boys of prepubertal age. The final height in boys was slightly lower than the mean, but in girls was similar to the general population. Both sexes attained their target height, although the height gain was less in boys. Poorer metabolic control was associated with reduced height gain.

A medical school general pathology course has been reformatted into a K-12 general pathology course. This new course has been implemented at a series of 7 to 12 grade levels and the student outcomes compared. Typically, topics covered mirrored those in a medical school general pathology course serving as an introduction to the mechanisms of diseases. Assessment of student performance was based on their score on a multiple-choice final examination modeled after an examination given to medical students. Two Tucson area schools, in a charter school network, participated in the study. Statistical analysis of examination performances showed that there were no significant differences as a function of school ( F = 0.258, P = .6128), with students at school A having an average test scores of 87.03 (standard deviation = 8.99) and school B 86.00 (standard deviation = 8.18; F = 0.258, P = .6128). Analysis of variance was also conducted on the test scores as a function of gender and class grade. There were no significant differences as a function of gender ( F = 0.608, P = .4382), with females having an average score of 87.18 (standard deviation = 7.24) and males 85.61 (standard deviation = 9.85). There were also no significant differences as a function of grade level ( F = 0.627, P = .6003), with 7th graders having an average of 85.10 (standard deviation = 8.90), 8th graders 86.00 (standard deviation = 9.95), 9th graders 89.67 (standard deviation = 5.52), and 12th graders 86.90 (standard deviation = 7.52). The results demonstrated that middle and upper school students performed equally well in K-12 general pathology. Student course evaluations showed that the course met the student's expectations. One class voted K-12 general pathology their "elective course-of-the-year."

Purpose: To compare quality of survival in “standard-risk” medulloblastoma after hyperfractionated radiation therapy of the central nervous system with that after standard radiation therapy, combined with a chemotherapy regimen common to both treatment arms, in the PNET4 randomised controlled trial. Methods and Materials: Participants in the PNET4 trial and their parents/caregivers in 7 participating anonymized countries completed standardized questionnaires in their own language on executive function, health status, behavior, health-related quality of life, and medical, educational, employment, and social information. Pre- and postoperative neurologic status and serial heights and weights were also recorded. Results: Data were provided by 151 ofmore » 244 eligible survivors (62%) at a median age at assessment of 15.2 years and median interval from diagnosis of 5.8 years. Compared with standard radiation therapy, hyperfractionated radiation therapy was associated with lower (ie, better) z-scores for executive function in all participants (mean intergroup difference 0.48 SDs, 95% confidence interval 0.16-0.81, P=.004), but health status, behavioral difficulties, and health-related quality of life z-scores were similar in the 2 treatment arms. Data on hearing impairment were equivocal. Hyperfractionated radiation therapy was also associated with greater decrement in height z-scores (mean intergroup difference 0.43 SDs, 95% confidence interval 0.10-0.76, P=.011). Conclusions: Hyperfractionated radiation therapy was associated with better executive function and worse growth but without accompanying change in health status, behavior, or quality of life.« less

Primary microvascular angina (PMA) is a common clinical condition associated to negative impact on quality of life (QOL) and reduced physical capacity. This study aimed at evaluating the effects of aerobic physical training (APT) on myocardial perfusion, physical capacity, and QOL in patients with PMA. We investigated 12 patients (53.8 ± 9.7 years old; 7 women) with PMA, characterized by angina, angiographycally normal coronary arteries, and reversible perfusion defects (RPDs) detected on (99m)Tc-sestamibi-SPECT myocardial perfusion scintigraphy (MPS). At baseline and after 4 month of APT, the patients underwent MPS, cardiopulmonary test, and QOL questionnaire. Stress-rest MPS images were visually analyzed by attributing semi-quantitative scores (0 = normal; 4 = absent uptake), using a 17-segment left ventricular model. Summed stress, rest, and difference scores (SDS) were calculated. In comparison to the baseline, in the post-training we observed a significant increase in peak-VO2 (19.4 ± 4.8 and 22.1 ± 6.2 mL·kg(-1)·minute(-1), respectively, P = .01), reduction of SDS (10.1 ± 8.8 and 2.8 ± 4.9, P = .008), and improvement in QOL scores. Physical training in patients with PMA is associated with reduction of myocardial perfusion abnormalities, increasing of physical capacity, and improvement in QOL. The findings of this hypothesis-generating study suggest that APT can be a valid therapeutic option for patients with PMA.

To investigate whether the outcome of treatment with trazodone CR in primary insomnia differs between patients with and without subthreshold depression. 14 patients (9 females, mean age 57.3 ± 13.3) with primary insomnia and increased Beck Depression Inventory (BDI) scores (>10) and 15 sex- and age-matched patients with primary insomnia and low BDI scores (≤ 10) were treated with trazodone CR 25-150 mg/d for 3 months and followed for 1 month after discontinuation of the medication. The Athens Insomnia Scale (AIS), Sheehan Disability Scale (SDS), and Clinical Global Impression scale (CGI) were completed at baseline, after each month of treatment and after the first week of run-out phase. Additional assessment tools comprised sleep diaries, the Leeds Sleep Evaluation Questionnaire (LSEQ) and actigraphic recordings. Subjective sleep time increased by 61.5 ± 72.3 min in the group with low BDI and 60.0 ± 59.4 min in the group with increased BDI at the end of the treatment phase. The significant improvements were also observed in the AIS, CGI, LSEQ and SDS. During the run-out phase the improvement was sustained in patients with low BDI, while AIS scores, sleep latency and total sleep time deteriorated in patients with increased BDI. Patients with subthreshold depression, even if the depressive symptoms do not fulfill the time criteria for depressive episode, show marked worsening of insomnia after discontinuation of sleep promoting medication.

RASopathies are developmental disorders caused by heterozygous germline mutations in genes encoding proteins in the RAS-MAPK signaling pathway. Reduced growth is a common feature. Several studies generated data on growth, final height (FH), and height velocity (HV) after growth hormone (GH) treatment in patients with these disorders, particularly in Noonan syndrome, the most common RASopathy. These studies, however, refer to heterogeneous cohorts in terms of molecular information, GH status, age at start and length of therapy, and GH dosage. This work reports growth data in 88 patients affected by RASopathies with molecularly confirmed diagnosis, together with statistics on body proportions, pubertal pattern, and FH in 33, including 16 treated with GH therapy for proven GH deficiency. Thirty-three patients showed GH deficiency after pharmacological tests, and were GH-treated for an average period of 6.8 ± 4.8 years. Before starting therapy, HV was -2.6 ± 1.3 SDS, and mean basal IGF1 levels were -2.0 ± 1.1 SDS. Long-term GH therapy, starting early during childhood, resulted in a positive height response compared with untreated patients (1.3 SDS in terms of height-gain), normalizing FH for Ranke standards but not for general population and Target Height. Pubertal timing negatively affected pubertal growth spurt and FH, with IGF1 standardized score increased from -2.43 to -0.27 SDS. During GH treatment, no significant change in bone age velocity, body proportions, or cardiovascular function was observed. © 2015 Wiley Periodicals, Inc.

Mass spectrometry (MS)-based protein identification depends mainly on protein extraction and digestion. Although sodium dodecyl sulfate (SDS) can preclude enzymatic digestion and interfere with MS analysis, it is still the most widely used surfactant in these steps. To overcome these disadvantages, a SDS-compatible proteomic technique for SDS removal prior to MS-based analyses was developed, namely filter-aided sample preparation (FASP). Herein, based on the effectiveness of sodium deoxycholate and a detergent removal spin column, we developed a modified FASP (mFASP) method and compared its overall performance, total number of peptides and proteins identified for shotgun proteomic experiments with that of the FASP method. Identification of 4570 ± 392 and 9139 ± 317 peptides and description of 862 ± 46 and 1377 ± 33 protein groups with two or more peptides from the ovarian cancer cell line A2780 was accomplished by FASP and mFASP methods, respectively. The mFASP method (21.2 ± 0.2%) had higher average peptide to protein coverage than FASP method (13.2 ± 0.5%). More hydrophobic peptides were identified by mFASP than by FASP, as indicated by the GRAVY score distribution. The reported method enables reliable and efficient identification of proteins and peptides in whole-cell extracts containing SDS. The new approach allows for higher throughput (the simultaneous identification of more proteins), a more comprehensive investigation of proteins, and potentially the discovery of new biomarkers.

Sleep disorders (SDs) are now recognized as a public health concern with considerable psychiatric and societal consequences specifically on the academic life of students. The aims of this study were to assess SDs in a group of university students in Lebanon and to examine the relationship between SDs and anxiety. An observational cross-sectional study was conducted at Saint-Joseph University, Lebanon, during the academic year 2013-2014. Four questionnaires were face-to-face administered to 462 students after obtaining their written consent: Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Generalized Anxiety Disorder 7-item scale (GAD-7). The prevalence of clinically significant insomnia was 10.6% (95% CI: 7.8-13.4%), more frequent in first year students. ISI mean score was 10.06 (SD = 3.76). 37.1% of the participants were poor sleepers. Excessive daytime sleepiness (EDS) and poor sleep were significantly more frequent among participants with clinical insomnia (p = 0.031 and 0.001 respectively). Clinically significant anxiety was more frequent in students suffering from clinical insomnia (p = 0.006) and in poor sleepers (p = 0.003). 50.8% of the participants with clinically significant anxiety presented EDS versus 30.9% of those with no clinically significant anxiety (p<0.0001). The magnitude of SDs in this sample of Lebanese university students demonstrate the importance of examining sleep health in this population. Moreover, the link between SD and anxiety reminds us of the importance of treating anxiety as soon as detected and not simply targeting the reduction of sleep problems.

Objective Cognitive symptoms are an important component of depression and the Perceived Deficits Questionnaire-Depression is one of only a few instruments available for the subjective assessment of cognitive dysfunction in depression. Thus, the present study aimed to validate a Korean version of the PDQ-D (K-PDQ-D) using patients with major depressive disorder (MDD). Methods This study included 128 MDD patients who were assessed at study entry and 86 of these patients were then completed 12 weeks of antidepressant monotherapy. All subjects were assessed with the K-PDQ-D, the Montgomery-Asberg Depression Rating Scale (MADRS), the Sheehan Disability Scale (SDS), the EuroQol-5 dimensions questionnaire (EQ-5D), and the number of sick leave days taken in the previous week. The internal consistency, Guttman’s split-half and test-retest reliabilities, factorial analyses, and concurrent and predictive validities of the K-PDQ-D were investigated. Results The K-PDQ-D exhibited excellent internal consistency and reliabilities, and was composed of four factors with high coefficients of determination. The concurrent validity analyses revealed that the K-PDQ-D scores were significantly correlated with the MADRS, SDS, and EQ-5D scores and the number of sick leave days taken. The K-PDQ-D scores at study entry significantly predicted changes in sick leave days and EQ-5D score from study entry to the 12-week endpoint. Conclusion The newly developed K-PDQ-D is a reliable and valid instrument for the evaluation of subjective cognitive symptoms in MDD patients. The K-PDQ-D may assist in the gathering of unique information regarding subjective cognitive complaints, which is important for the comprehensive evaluation of patients with MDD. PMID:26792037

The Healthy Lifestyles Programme (HeLP), a novel school-based intervention to prevent obesity in school children: study protocol for a randomised controlled trial

PubMed Central

2013-01-01

Background Over the last three decades there has been a substantial increase in the proportion of children who are overweight or obese. The Healthy Lifestyles Programme (HeLP) is a novel school-based intervention, using highly interactive and creative delivery methods to prevent obesity in children. Methods/Design We describe a cluster randomised controlled trial to evaluate the effectiveness and cost effectiveness of HeLP. The intervention has been developed using intervention mapping (involving extensive stakeholder involvement) and has been guided by the Information, Motivation, Behavioural Skills model. HeLP includes creating a receptive environment, drama activities, goal setting and reinforcement activities and runs over three school terms. Piloting showed that 9 to 10 year olds were the most receptive and participative. This study aims to recruit 1,300 children from 32 schools (over half of which will have ≥19% of pupils eligible for free school meals) from the southwest of England. Participating schools will be randomised to intervention or control groups with baseline measures taken prior to randomisation. The primary outcome is change in body mass index standard deviation score (BMI SDS) at 24 months post baseline. Secondary outcomes include, waist circumference and percent body fat SDS and proportion of children classified as overweight or obese at 18 and 24 months and objectively measured physical activity and food intake at 18 months. Between-group comparisons will be made using random effects regression analysis taking into account the hierarchical nature of the study design. An economic evaluation will estimate the incremental cost-effectiveness of HeLP, compared to control, from the perspective of the National Health Service (NHS)/third party payer. An in-depth process evaluation will provide insight into how HeLP works, and whether there is any differential uptake or engagement with the programme. Discussion The results of the trial will provide evidence on the effectiveness and cost effectiveness of the Healthy Lifestyles Programme in affecting the weight status of children.

To characterize the clinical and immunological features of HLA-typed youth with pediatric onset of type 2 diabetes mellitus (T2DM). One hundred and seven patients with clinically diagnosed T2DM (aged ≤20 yr at diagnosis) were examined. DNA and serum, obtained after a median diabetes duration of 2.2 (Q1-Q3: 0.8-4.6) yr, were used for centralized HLA-typing and autoantibody (GADA, IA-2A, ZnT8A) measurements. 64.6% of patients were female and median age at diagnosis was 13.8 (Q1-Q3: 11.6-15.4) yr. Patients were obese [median body mass index-standard deviation score (BMI-SDS): 2.6 (2.0-3.1)], 88.0% had a family history of diabetes and 40.2% a migration background. Islet autoantibodies were detected in 16 (15.0%), among which 7 (6.5%) had multiple islet autoantibodies. Autoantibody positive patients had poorer metabolic control than autoantibody negative patients [glycosylated hemoglobin A1c (HbA1c): 8.1 (6.9-10.1) % vs. 6.6 (5.9-8.0) %; p = 0.033], while patients with HLA-DR genetic risk had higher BMI-SDS than those with HLA-DRXX [2.6 (2.4-3.7) vs. 2.4 (1.7-2.9); p = 0.007]. Metabolic syndrome (61.7%), microalbuminuria (13.4%), and retinopathy (3.9%) were diagnosed. Therapies used were lifestyle only (35.5%), oral anti-diabetics (OAD) only (43.3 %), insulin +  OAD (15.9%) and insulin only (5.6%). Patients with β-cell autoimmunity or HLA-DR genetic risk more frequently used insulin than confirmed T2DM patients (50.0 vs. 22.0%; p = 0.037) and less often had diabetic relatives (61.1 vs. 86.0%; p = 0.030). T2DM was confirmed in about 90% of patients while about 10% with β-cell autoimmunity or HLA-DR genetic risk likely had either T1.5DM or 'double diabetes' or an unknown diabetes type. © 2013 John Wiley & Sons A/S.

Little information is available on a long-term follow-up in Bartter syndrome type I and II. Clinical presentation, treatment and long-term follow-up (5.0-21, median 11 years) were evaluated in 15 Italian patients with homozygous (n = 7) or compound heterozygous (n = 8) mutations in the SLC12A1 (n = 10) or KCNJ1 (n = 5) genes. Thirteen new mutations were identified. The 15 children were born pre-term with a normal for gestational age body weight. Medical treatment at the last follow-up control included supplementation with potassium in 13, non-steroidal anti-inflammatory agents in 12 and gastroprotective drugs in five patients. At last follow-up, body weight and height were within normal ranges in the patients. Glomerular filtration rate was <90 mL/min/1.73 m(2) in four patients (one of them with a pathologically increased urinary protein excretion). In three patients, abdominal ultrasound detected gallstones. The group of patients with antenatal Bartter syndrome had a lower renin ratio (P < 0.05) and a higher standard deviation score (SDS) for height (P < 0.05) than a previously studied group of patients with classical Bartter syndrome. Patients with Bartter syndrome type I and II tend to present a satisfactory prognosis after a median follow-up of more than 10 years. Gallstones might represent a new complication of antenatal Bartter syndrome.

X-linked hypophosphatemia (XLH) is characterized by low serum phosphorus, relative 1,25-dihydroxyvitamin D(3) deficiency and rickets. It is caused by mutations in the phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX). The conventional treatment of XLH includes the administration of phosphate and calcitriol; however, treated patients usually present with a short stature. Therefore, additional coexistent defects, such as GH deficiency, are under debate. Two male siblings presented with a disproportionate growth failure and rickets. Investigation of calcium and phosphate metabolism, molecular genetic analysis of the PHEX gene and GH function tests were initiated. Both patients showed typical clinical and biochemical signs of XLH. Molecular genetic analysis revealed a 747 CGA (Arg)-TGA (End) mutation in exon 22 of the PHEX gene, confirming XLH. Since treatment with phosphate and calcitriol alone failed to improve growth in both patients, the GH axis was examined and a partial GH deficiency was diagnosed in both cases. Almost 3 Years of additional therapy with recombinant human GH (rhGH) led to a significant improvement of height standard deviation scores (HtSDS). Poor growth in XLH may, in at least some patients, be aggravated by GH deficiency. Hence, GH deficiency should be considered in extremely poorly growing patients with XLH, because these patients are likely to benefit from rhGH therapy.

To assess patient satisfaction with exercise for knee osteoarthritis (OA). A convenience sample of 27 patients recruited to a randomized controlled trial (RCT) comparing open kinetic chain and closed kinetic chain exercises for knee OA were reassessed at nine months post-randomization. Clinical outcomes included self-report and physical performance measures of function and pain severity. Patients also completed the Physiotherapy Outpatient Survey (POPS), which is a multi-dimensional measure of patient satisfaction with physiotherapy. There was no significant difference in satisfaction between the two intervention groups. Overall mean satisfaction for the entire cohort was 4.07 of a maximum score of 5 (standard deviation (SD) = 0.52). Lower levels of satisfaction with outcome (mean = 3.56, SD = 0.8) were reported compared with other domains of expectations, communication, organization and the therapist (mean = 3.79-4.49; SDs = 0.42-0.92). Both intervention groups improved from baseline on clinical outcomes of pain, self-report function and walking distance, with no significant differences between the two groups. High levels of satisfaction were reported in this subsample of knee OA patients participating in an RCT evaluating the effects of different exercise approaches for knee OA. Satisfaction varied depending on the satisfaction domain, with lower satisfaction with outcome compared with other aspects of care. The POPS questionnaire can be used to measure the multi-dimensional aspects of satisfaction with physiotherapy.

Children with ultra-short bowel syndrome (USBS) have not been extensively studied to date because the condition is rare. The aim of the study was to assess the nutritional status of children with USBS receiving home parenteral nutrition, using citrulline serum concentration and cholestasis. We studied 17 patients with USBS, with a median age of 6.6 years and median duration of parenteral nutrition of 6.6 years. The study was carried out at The Children's Memorial Health Institute, Warsaw, from January 2014 to January 2015. The median standard deviation score (SDS) was -1.2 for body mass according to chronological age, -1.72 according to height and -0.59 according to height for age. Patients requiring seven days per week parenteral nutrition had a citrulline concentration below 10 μmol/L. Decreased bone-mineral density was observed in 87% of the patients. Low values of 25-hydroxyvitamin D were found in 53% of the children. None of the patients had elevated conjugated bilirubin levels above 34.2 μmol/L. Children with USBS were growth deficient according to their chronological age, with frequent abnormal bone mineralisation and vitamin D deficiency. Children requiring parenteral nutrition seven days a week had citrulline concentrations below 10 μmol/L. Cholestasis was not seen. ©2018 The Authors.

Regular physical exercise within structured lifestyle programs may improve weight status and minimize metabolic risk factors in childhood obesity. The aim of this study was to evaluate the effect of the one-year combined physical exercise/lifestyle program KLAKS on anthropometric and metabolic parameters and glycemic control in childhood obesity. 142 overweight/obese (BMI>90th percentile) candidates (7-18years) were enrolled, 115 participants completed the program. Anthropometrics and biochemical parameters were obtained at beginning and completion. An oral glucose tolerance test (OGTT) was performed in a subgroup of participants. Course of glucose and insulin levels within OGTT was correlated with several parameters and is reported here for those who completed the program. The mean standard deviation scores (SDS) decreased significantly for BMI, waist circumference, waist-to-height ratio (WHtR) and percentage body fat (all p≤0.01). Improved metabolic risk markers included mean glucose levels within an OGTT at follow-up compared to baseline (p<0.0001) and HbA1c (p=0.05) as well as indications of improvement for gamma-glutamyl-transferase and free fatty acids. The one-year combined exercise/lifestyle program KLAKS significantly improves markers of obesity and glycemic control. Impaired cardiometabolic risk markers, even subclinical, are also favorably influenced by program participation. Copyright © 2014 Elsevier Inc. All rights reserved.

The Effect of Paid Leave on Maternal Mental Health.

2018-06-07

Objectives I examined the relationship between paid maternity leave and maternal mental health among women returning to work within 12 weeks of childbirth, after 12 weeks, and those returning specifically to full-time work within 12 weeks of giving birth. Methods I used data from 3850 women who worked full-time before childbirth from the Early Childhood Longitudinal Study-Birth Cohort. I utilized propensity score matching techniques to address selection bias. Mental health was measured using the Center for Epidemiologic Studies Depression (CESD) scale, with high scores indicating greater depressive symptoms. Results Returning to work after giving birth provided psychological benefits to women who used to work full-time before childbirth. The average CESD score of women who returned to work was 0.15 standard deviation (p < 0.01) lower than the average CESD score of all women who worked full-time before giving birth. Shorter leave, on the other hand, was associated with adverse effects on mental health. The average CESD score of women who returned within 12 weeks of giving birth was 0.13 standard deviation higher (p < 0.05) than the average CESD score of all women who rejoined labor market within 9 months of giving birth. However, receipt of paid leave was associated with an improved mental health outcome. Among all women who returned to work within 12 weeks of childbirth, those women who received some paid leave had a 0.17 standard deviation (p < 0.05) lower CESD score than the average CESD score. The result was stronger for women who returned to full-time work within 12 weeks of giving birth, with a 0.32 standard deviation (p < 0.01) lower CESD score than the average CESD score. Conclusions The study revealed that the negative psychological effect of early return to work after giving birth was alleviated when women received paid leave.

The purpose of this investigation was to examine the effects of combined aerobic and resistance exercise training among self-reported mood disturbances, perceived stress, frequency of self-reported symptoms, and symptom distress in a sample of HIV+ adults. For this purpose, 49 participants were randomly assigned into an exercise (EX) or control (CON) group. Those in the EX group completed 50 min of supervised aerobic and resistance training at a moderate intensity twice a week for 6 weeks. The CON group reported to the university and engaged in sedentary activities. Data were collected at baseline before randomization and 6 weeks post intervention. Measures included the symptom distress scale (SDS), perceived stress scale (PSS), profile of mood states (POMS) total score, and the POMS sub-scale for depression and fatigue. A 2 way ANOVA was used to compare between and within group interactions. The EX group showed a significant decrease in reported depression scores (p=0.03) and total POMS (p=0.003). The CON group reported no change in POMS or SDS, but showed a significant increase in PSS. These findings indicate that combination aerobic and resistance training completed at a moderate intensity at least twice a week provides additional psychological benefits independent of disease status and related symptoms. © Georg Thieme Verlag KG Stuttgart · New York.

BackgroundTo determine if a key marker of socioeconomic status, maternal education, is associated with later neurocognitive and academic outcomes among children born extremely preterm (EP).MethodEight hundred and seventy-three children born at 23 to 27 weeks of gestation were assessed for cognitive and academic ability at age 10 years. With adjustments for gestational age (GA) and potential confounders, outcomes of children whose mothers had fewer years of education at the time of delivery and children whose mother advanced in education between birth and 10 years were examined.ResultsChildren of mothers in the lowest education stratum at birth were significantly more likely to score ≥2 SDs below normative expectation on 17 of 18 tests administered. Children of mothers who advanced in education (n=199) were at reduced risk for scoring ≥2 SDs on 15 of 18 measures, but this reduction was statistically significant on only 2 of 18 measures.ConclusionAmong EP children, socioeconomic disadvantage at birth, indexed by maternal education, is associated with significantly poorer neurocognitive and academic outcomes at 10 years of age, independently of GA. Maternal educational advancement during the child's first 10 years of life is associated with modestly improved neurocognitive outcomes.

The use of movies in medical (particularly psychiatric) education has been often limited to portraits of mental illness and psychiatrists. The Psychiatric Institute of the Università del Piemonte Orientale has a longstanding tradition of working with/on movies according to a method developed by Eugenio Torre, using dynamic images as educational incitements. Our aim is to describe the preliminary results on the impact of this intervention in medical students. The cinemeducation project lasted 6 months, and included 12 meetings. Forty randomly selected participants were assessed with: Attitudes Towards Psychiatry Scale (ATP-30), Social Distance Scale (SDS), Interpersonal Reactivity Index (IRI), and Toronto Alexithymia Scale (TAS), both at baseline and after 6 months, when the workshop was concluded. A significant increase was found in the ATP-30 score, and a reduction of the SDS and IRI-Personal Distress scale scores. Informal feedback from participants was strongly positive. Preliminary results from the assessment of participants are encouraging. Students' attitudes towards psychiatry and ability to tolerate anxiety when experiencing others' distress improved, while stigma decreased. The evocative power of movie dynamic images, developed in the group and integrated with the help of the group leader, can enrich students' knowledge, both from a cognitive and emotional standpoint.

To compare the postoperative analgesic effects of intravenous (IV), intramuscular (IM), subcutaneous (SC) or oral transmucosal (OTM) buprenorphine administered to cats undergoing ovariohysterectomy. Randomized, prospective and blinded clinical trial. 100 female cats. Cats were assigned to receive 0.01 mg kg(-1) of buprenorphine administered by the IV, IM, SC or OTM route (n = 25/group). Buprenorphine was made up to 0.3 mL with 0.9% saline. DIVAS (0-100 mm) and simple descriptive scale (SDS) (from 0 to 4) pain and sedation scores were assigned to each cat before and 1, 2, 3, 4, 6, 8, 12 and 24 hours after ovariohysterectomy. Buprenorphine and carprofen were administered for rescue analgesia. Data were analyzed using anova and Fisher's exact test (p < 0.05). There were no significant differences between groups for breed, body weight, anesthetic time or surgery time (p > 0.05). There were no significant differences between groups for sedation scores at any time. SDS pain scores did not detect any differences between groups (p > 0.05). DIVAS pain scores after OTM administration were significantly higher than IV and IM administration at 1 hour and at 3, 4, 6, 8 and 12 hours, respectively (p < 0.05). DIVAS pain scores after SC administration were significantly higher than IV and IM administration at 2 hours and at 2, 3, 4, 8, 12 and 24 hours (p < 0.05), respectively. Six, four, 13 and 17 cats that received IV, IM, SC and OTM buprenorphine required rescue analgesia, respectively. There was a significantly higher incidence of treatment failure in cats that received SC and OTM buprenorphine compared with cats that received IV and IM buprenorphine (p < 0.05). IV and IM administration of buprenorphine provided better postoperative analgesia than SC or OTM administration of the drug and these routes of administration should be preferred when buprenorphine is administered to cats.

Background: Patients with major depressive disorder (MDD) who fail to achieve complete remission with antidepressant therapy may benefit from augmentation therapy with an atypical antipsychotic. Method: A pooled analysis was performed on 2 identical 14-week studies (8-week prospective antidepressant therapy treatment phase followed by 6-week randomized double-blind phase) evaluating the efficacy of adjunctive aripiprazole (2–20 mg/day) in DSM-IV-TR–defined MDD patients with an inadequate response to antidepressant therapy. Primary efficacy endpoint was the mean change in Montgomery-Asberg Depression Rating Scale (MADRS) total score from end of the prospective phase (week 8) to end of randomized phase (week 14, last observation carried forward). Subgroup analyses were performed. The key secondary endpoint was mean change in Sheehan Disability Scale (SDS) mean score. Results: At endpoint, mean change in MADRS total score was significantly greater with adjunctive aripiprazole (–8.7) than with adjunctive placebo (–5.7; p < .001). Except for a differential treatment-by-sex interaction, change in MADRS total scores were consistently greater with adjunctive aripiprazole than with adjunctive placebo, regardless of race, age, episode duration, prior antidepressant therapy response, number of historical treatment failures, severity of depressive symptoms, and antidepressant. At endpoint, MADRS remission rates were significantly greater with adjunctive aripiprazole than with placebo (25.7% vs. 15.4%; p < .001). Adjunctive aripiprazole also demonstrated significantly greater improvements in mean change from baseline in SDS total score than adjunctive placebo (–1.2 vs. –0.6; p = .001). Conclusion: Augmentation of antidepressant therapy with the atypical antipsychotic aripiprazole resulted in significant efficacy benefits across a range of subgroups of patients with MDD. Further study of a treatment-by-sex interaction is needed. Trial Registration: www.clinicaltrials.gov Identifiers: NCT00095823 and NCT00095758 PMID:19287552

The stigma of major depressive disorder (MDD) is an important public health problem. This study evaluated stigma in MDD patients in China using explanatory model interview catalogue (EMIC) questionnaire and the demographic and clinical symptom factors associated with the stigma of these patients. A total of 158 MDD patients from domestic 3 mental health centers were surveyed. We used the EMIC questionnaire to assess stigma of these patients, Montgomery and Asberg depression rating scale (MADRS) to assess depressive severity, self-reporting inventory (SCL-90) to assess mental health level, Sheehan disability scale (SDS) to assess social function, and fatigue severity scale (FSS) to assess degree of fatigue. The stigma scores were significantly higher in the 18- to 30-year-old (z = 2.875, P = .024) and 31- to 40-year-old (z = 3.204, P = .008) groups than the 51- to 65-year-old group; in the full-time employment group than the retired group (z = 3.163, P = .016). The stigma scores exhibited significant negative correlation with age (r = -0.169, P = .034) but positive correlations with the scores of MADRS (r = .212, P = .007), total scores (r = .273, P = .001) and subscales of interpersonal sensitivity (r = .233, P = .003), depression (r = .336, P < .001), and anxiety (r = .228, P = .004) of SCL-90, scores of FSS (r = .230, P = .004), and SDS (r = .254, P = .001). Multivariate regression analysis revealed that depression subscale of SCL-90 and FSS were independently correlated with stigma. The age, employment status, fatigue, and depressive severity are closely associated with the perceived stigma of MDD patients and may be important factors considered for stigma interventions of MDD in China. © 2016 John Wiley & Sons Australia, Ltd.

This study examined the use of the Tucker linear equating method in producing an individual student's score in 3 groups with bridging stations over 3 consecutive days of the clinical performance examination (CPX) and compared the differences in scoring patterns by bridging number. Data were drawn from 88 examinees from 3 different CPX groups-DAY1, DAY2, and DAY3-each of which comprised of 6 stations. Each group had 3 common stations, and each group had 2 or 3 stations that differed from other groups. DAY1 and DAY3 were equated to DAY2. Equated mean scores and standard deviations were compared with the originals. DAY1 and DAY3 were equated again, and the differences in scores (equated score-raw score) were compared between the 3 sets of equated scores. By equating to DAY2, DAY1 decreased in mean score from 58.188 to 56.549 and in standard deviation from 4.991 to 5.046, and DAY3 fell in mean score from 58.351 to 58.057 and in standard deviation from 5.546 to 5.856, which demonstrates that the scores of examinees in DAY1 and DAY2 were accentuated after use of the equation. The patterns in score differences between the equated sets to DAY1, DAY2, and DAY3 yielded information on the soundness of the equating results from individual and overall comparisons. To generate equated scores between 3 groups on 3 consecutive days of the CPX, we applied the Tucker linear equating method. We also present a method of equating reciprocal days to the anchoring day as much as bridging stations.

In this study we evaluated the usability of the Gait Deviation Index (GDI), an index that summarizes the amount of deviation in movement from a standard norm, in adults with rheumatoid arthritis (RA). The aims of the study were to evaluate the ability of the GDI to identify gait deviations, assess inter-trial repeatability, and examine the relationship between the GDI and walking speed, physical disability, and pain. Sixty-three adults with RA and 59 adults with typical gait patterns were included in this retrospective case-control study. Following a three-dimensional gait analysis (3DGA), representative gait cycles were selected and GDI scores calculated. To evaluate the effect of walking speed, GDI scores were calculated using both a free-speed and a speed-matched reference set. Physical disability was assessed using the Health Assessment Questionnaire (HAQ) and subjects rated their pain during walking. Adults with RA had significantly increased gait deviations compared to healthy individuals, as shown by lower GDI scores [87.9 (SD = 8.7) vs. 99.4 (SD = 8.3), p < 0.001]. This difference was also seen when adjusting for walking speed [91.7 (SD = 9.0) vs. 99.9 (SD = 8.6), p < 0.001]. It was estimated that a change of ≥ 5 GDI units was required to account for natural variation in gait. There was no evident relationship between GDI and low/high RA-related physical disability and pain. The GDI seems to useful for identifying and summarizing gait deviations in individuals with RA. Thus, we consider that the GDI provides an overall measure of gait deviation that may reflect lower extremity pathology and may help clinicians to understand the impact of RA on gait dynamics.

Bee venom (BV) is a complex mixture of proteins and contains proteins such as phospholipase and melittin, which have an effect on blood clotting and blood clots. The mechanism of action of honey bee venom (HBV, Apis mellifera) on human plasma proteins and its anti-thrombotic effect were studied. The purpose of this study was to investigate the anti-coagulation effect of BV and its effects on blood coagulation and purification. Crude venom obtained from Apis mellifera was selected. The anti-coagulation factor of the crude venom from this species was purified by using gel filtration chromatography (sephadex G-50), and the molecular weights of the anti-coagulants in this venom estimated by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Blood samples were obtained from 10 rabbits, and the prothrombin time (PT) and the partial thromboplastin time (PTT) tests were conducted. The approximate lethal dose (LD) values of BV were determined. Crude BV increased the blood clotting time. For BV concentrations from 1 to 4 mg/mL, clotting was not observed even at more than 300 seconds, standard deviations (SDs) = ± 0.71; however, clotting was observed in the control group 13.8 s, SDs = ± 0.52. Thus, BV can be considered as containing anti-coagulation factors. Crude BV is composed 4 protein bands with molecular weights of 3, 15, 20 and 41 kilodalton (kDa), respectively. The LD50 of the crude BV was found to be 177.8 μg/mouse. BV contains anti-coagulation factors. The fraction extracted from the Iranian bees contains proteins that are similar to anti-coagulation proteins, such as phospholipase A2 (PLA2) and melittin, and that can increase the blood clotting times in vitro.

To investigate the intakes of dietary calcium/dairy and the current prevalence of overweight and obesity among children and adolescents aged 7-15 in Longquanyi District, Chengdu, and to explore the association of dietary calcium and dairy intake with overweight/obesity. 1738 children and adolescents were recruited in the cross-sectional study using cluster random sampling method. Information on dietary calcium and dairy intakes was collected using 24-hour dietary recall and food frequency questionnaire (FFQ). Height, weight and waist circumference were measured to calculate body mass index (BMI)/waist-to-height ratio (WHtR) and body mass index standard deviation (BMI SDS). Overweight/obesity was defined based on the criteria of Working Group on Obesity in China (WGOC). Participants were grouped into 3 categories indicating lower, moderate and higher intakes of dietary calcium and dairy, respectively. The association of dietary calcium and dairy consumption with (BMI SDS) /WHtR and the prevalence of overweight/obesity was analyzed after being stratified by gender and age. The prevalence of overweight/obesity in boys and girls were 11.92%/7.04% and 8.04%/6.30%, respectively. The intake of dietary calcium and dairy in girls were much higher than that in boys (P < 0.0001). Among boys aged 7-9 years, those with higher consumption of dairy had the higher BMI SDS (P = 0.01). Among boys aged 10-12 years, those with higher consumption of dietary calcium had the lowest prevalence of overweight (P = 0.03). However, similar results were not observed among girls. Dietary calcium and dairy intakes seemed to be related to overweight/ obesity in boys, however the associations were inconsistent among different age groups. Associations between consumption of calcium, dairy and overweight/obesity were not found among girls.

Objectives: Bee venom (BV) is a complex mixture of proteins and contains proteins such as phospholipase and melittin, which have an effect on blood clotting and blood clots. The mechanism of action of honey bee venom (HBV, Apis mellifera) on human plasma proteins and its anti-thrombotic effect were studied. The purpose of this study was to investigate the anti-coagulation effect of BV and its effects on blood coagulation and purification. Methods: Crude venom obtained from Apis mellifera was selected. The anti-coagulation factor of the crude venom from this species was purified by using gel filtration chromatography (sephadex G-50), and the molecular weights of the anti-coagulants in this venom estimated by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Blood samples were obtained from 10 rabbits, and the prothrombin time (PT) and the partial thromboplastin time (PTT) tests were conducted. The approximate lethal dose (LD) values of BV were determined. Results: Crude BV increased the blood clotting time. For BV concentrations from 1 to 4 mg/mL, clotting was not observed even at more than 300 seconds, standard deviations (SDs) = ± 0.71; however, clotting was observed in the control group 13.8 s, SDs = ± 0.52. Thus, BV can be considered as containing anti-coagulation factors. Crude BV is composed 4 protein bands with molecular weights of 3, 15, 20 and 41 kilodalton (kDa), respectively. The LD50 of the crude BV was found to be 177.8 μg/mouse. Conclusion: BV contains anti-coagulation factors. The fraction extracted from the Iranian bees contains proteins that are similar to anti-coagulation proteins, such as phospholipase A2 (PLA2) and melittin, and that can increase the blood clotting times in vitro.

Short stature is associated with increased risk of ill health and mortality and can negatively impact on an individual's economic opportunity and psychological well-being. The aim of this study was to investigate the association between height and area-level deprivation by ethnic group in children in England. Cross-sectional analysis of data gathered from the National Child Measurement Programme 2008/2009 to 2012/2013. Children (n=1 213 230) aged 4-5 and 10-11 years attending state-maintained primary schools in England. Mean height SD score (SDS) (based on the British 1990 growth reference) was calculated for children by Income Deprivation Affecting Children Index as a measure of area-level deprivation. Analyses were performed by sex and age group for white British, Asian and black ethnicities. For white British children mean height decreased 0.2 SDS between the least and the most deprived quintile. For Asian children the relationship was weaker and varied between 0.08 and 0.18 SDS. For white British boys the magnitude of association was similar across age groups; for Asian boys the magnitude was higher in the age group of 10-11 years and in white British girls aged 10-11 years the association decreased. Height SDS was similar across all levels of deprivation for black children. Social inequalities were shown in the height of children from white British and Asian ethnic groups. Further evaluation of height in black children is warranted. Action is needed to reduce inequalities in height by addressing the modifiable negative environmental factors that prevent healthy growth and development of children.

Childhood growth affects long-term health and could contribute to health inequalities that persist throughout life. We compared growth data of 4-year-old to 6-year-old children born 1997-2002 in UK (n=15,168), Sweden (n=6749) and rural China (n=10,327). SD scores (SDS) were calculated against the WHO Growth Standard. Obesity and overweight were defined by the International Obesity Taskforce cut-offs, and stunting, underweight and thinness by height, weight or body mass index (BMI)<-2 SDS. Associations with maternal education were standardised by calculating the Slope Index of Inequality (SII). Mean SDS height, weight and BMI in the UK (-0.01, 0.42, 0.62, respectively) and Sweden (0.45, 0.59, 0.45) were higher than in China (-0.98, -0.82, -0.29). Higher maternal education was consistently associated with taller offspring height SDS (SII: UK 0.25; Sweden 0.17; China 1.06). Underweight and stunting were less common in the UK (prevalence: 0.6% and 2.2%, respectively) and Sweden (0.3% and 0.6%) than in China (9.5% and 16.4%), where these outcomes were inversely associated with maternal education (SII: -25.8% and -12.7%). Obesity prevalence in the UK, Sweden and China was 4.8%, 3.7% and 0.4%, respectively. Maternal education was inversely associated with offspring obesity in the UK (SII: -3.3%) and Sweden (-2.8%), but not in China (+0.3%). Higher maternal education was associated with more favourable growth in young children: lower obesity and overweight in the UK and Sweden, and lower stunting and underweight in rural China. Public health strategies to optimise growth in early childhood need to acknowledge socioeconomic factors, but possibly with a different emphasis in different settings.

Abstract The aim of this study was to clarify the predictive value of fractional flow reserve (FFR) determined by myocardial perfusion imaging (MPI) using thallium (Tl)-201 IQ-SPECT without and with computed tomography-based attenuation correction (CT-AC) for patients with stable coronary artery disease (CAD). We assessed 212 angiographically identified diseased vessels using adenosine-stress Tl-201 MPI-IQ-SPECT/CT in 84 consecutive, prospectively identified patients with stable CAD. We compared the FFR in 136 of the 212 diseased vessels using visual semiquantitative interpretations of corresponding territories on MPI-IQ-SPECT images without and with CT-AC. FFR inversely correlated most accurately with regional summed difference scores (rSDS) in images without and with CT-AC (r = −0.584 and r = −0.568, respectively, both P < .001). Receiver-operating characteristics analyses using rSDS revealed an optimal FFR cut-off of <0.80 without and with CT-AC. Although the diagnostic accuracy of FFR <0.80 did not significantly differ, FFR ≥0.82 was significantly more accurate with, than without CT-AC. Regions with rSDS ≥2 without or with CT-AC predicted FFR <0.80, and those with rSDS ≤1 without and with CT-AC predicted FFR ≥0.81, with 73% and 83% sensitivity, 84% and 67% specificity, and 79% and 75% accuracy, respectively. Although limited by the sample size and the single-center design, these findings showed that the IQ-SPECT system can predict FFR at an optimal cut-off of <0.80, and we propose a novel application of CT-AC to MPI-IQ-SPECT for predicting clinically significant and insignificant FFR even in nonobese patients.

Patient mortality is significantly reduced by rapid identification of bacteria from sterile sites. MALDI-TOF can identify bacteria directly from positive blood cultures and multiple sample preparation methods are available. We evaluated three sample preparation methods and two MALDI-TOF score cut-off values. Positive blood culture bottles with organisms present in Gram stains were prospectively analysed by MALDI-TOF. Three lysis reagents (Saponin, SDS, and SepsiTyper lysis bufer) were applied to each positive culture followed by centrifugation, washing and protein extraction steps. Methods were compared using the McNemar test and 16S rDNA sequencing was used to assess discordant results. In 144 monomicrobial cultures, using ≥2.000 as the cut-off value, species level identifications were obtained from 69/144 (48%) samples using Saponin, 86/144 (60%) using SDS, and 91/144 (63%) using SepsiTyper. The difference between SDS and SepsiTyper was not statistically significant (P = 0.228). Differences between Saponin and the other two reagents were significant (P < 0.01). Using ≥1.700 plus top three results matching as the cut-off value, species level identifications were obtained from 100/144 (69%) samples using Saponin, 103/144 (72%) using SDS, and 106/144 (74%) using SepsiTyper and there was no statistical difference between the methods. No true discordances between culture and direct MALDI-TOF identification were observed in monomicrobial cultures. In 32 polymicrobial cultures, MALDI-TOF identified one organism in 34-75% of samples depending on the method. This study demonstrates two inexpensive in-house detergent lysis methods are non-inferior to a commercial kit for analysis of positive blood cultures by direct MALDI-TOF in a clinical diagnostic microbiology laboratory.

Rapid weight gain in infancy is associated with higher body mass index in later life, but its relation with individual body-composition components remains unclear. We aimed to investigate associations between weight gain during different periods in infancy and later fat mass (FM) and fat-free mass (FFM). Body composition was assessed by using the 4-component model, dual-energy X-ray absorptiometry, and anthropometry in 234 healthy UK children and adolescents (105 boys; x +/- SD age: 11.4 +/- 3.8 y). Early growth measurements were prospective in 52 subjects and retrospective in 182. Relative weight gain was calculated as change in SD score (SDS) during different periods. Relative weight gain from 0 to 3 mo and from 3 to 6 mo showed positive relations with childhood FM, waist circumference, and trunk FM that were equivalent to increases in FMI (FM/height(2)) of 0.24 SDS (95% CI: 0.04, 0.44) and 0.50 SDS (0.25, 0.75) per 1-SDS increase in early weight and that were comparable to the effect of current obesity risk factors. Relative weight gain from 0 to 3 mo was also positively associated with later FFMI (FFM/height(2)). Relative weight gain from 6 to 12 mo was not associated with later body composition. Associations were independent of birth weight, sex, puberty, physical activity, socioeconomic class, ethnicity, and parental body mass index. In this Western population, greater relative weight gain during early infancy was positively associated with later FM and central fat distribution and with FFM. Rapid weight gain in infancy may be a risk factor for later adiposity. Early infancy may provide an opportunity for interventions aimed at reducing later obesity risk.

Due to the pandemic of childhood obesity and thus obesity-related hypertension, improvements in treatment availability are needed. Hence, we investigated whether reductions in blood pressure (BP) would occur in children with overweight and obesity exhibiting prehypertension/hypertension during a community-based overweight and obesity treatment program, and if changes in body mass index (BMI) are associated with changes in BP. The study included 663 children aged 3-18 years with a BMI ⩾85th percentile for sex and age that entered treatment from June 2012 to January 2015. Height, weight and BP were measured upon entry and every 3-6 months. BMI and BP s.d. scores (SDSs) were calculated according to sex and age, or sex, age and height. Prehypertension was defined as a BP SDS ⩾1.28 and <1.65. Hypertension was defined as a BP SDS ⩾1.65. Upon entry, 52% exhibited prehypertension (11.9%) or exhibited hypertension (40.1%). After 12 months (range: 3-29) of treatment, 29.3% of the children with prehypertension/hypertension were normotensive. Children with systolic prehypertension/hypertension upon entry reduced their systolic BP SDSs by 0.31 (95% confidence interval (CI): 0.70-0.83, P<0.0001). Children with diastolic prehypertension/hypertension upon entry reduced their diastolic BP SDSs by 0.78 (95% CI: 0.78-0.86, P<0.0001). BMI SDS changes were positively associated with BP SDS changes (P<0.0001). Nonetheless, some children reduced BP SDSs while increasing their BMI SDSs, and prehypertension/hypertension developed in 23.3% of the normotensive children despite reductions in BMI SDSs (P<0.0001). These results suggest that community-based overweight and obesity treatment can reduce BP, and thus may help improve treatment availability.

Objective: To investigate the prevalence and psychosocial characteristics in inpatients with head and neck cancer before surgery. Method: From September 2015 to December 2016, 237 consecutive inpatients with head and neck cancer who had been scheduled for surgery were prospectively enrolled in Department of Head and Neck Surgery of Shanxi Provincial Tumor Hospital. Mental health symptoms were systematically investigated using three psychological instruments: symptom checklist-90 (SCL-90), Zung self-rating anxiety scale (SAS) and Zung self-rating depression scale (SDS). SPSS 17.0 software was used to analyze the data. And he results of SCL-90, SAS and SDS were compared with the Chinese norm. For all statistical analyses, a P value <0.05 was considered statistically significant. Result: Of 237 patients, 228 (96.2%) completed all the questionnaire. The scores of SCL-90 (1.60±0.44), SAS (46.67±8.51)and SDS(47.50±11.43)in patients with head and neck cancer were significantly higher than those of Chinese norm ( t =3.093, t =17.29, t =4.29 respectively and P =0.003, P =0.001, P =0.001 respectively). Positive proportion identified by three measure tools are 32.9%, 35.5% and 36.8% respectively. And 42 patients (18.4%) suffered from both anxiety and depression. The SCL-90 scores were significantly higher than those of the normal standard population, including dimension of somatization obsessive-compulsive, anxiety, hostility, phobic-anxiety and psychoticism ( t =4.47, 3.04, 2.87, 2.58, 5.46, 4.15 respectively, all P <0.05). Conclusions: This study offers important information regarding psychological status in inpatients with head and neck cancer before surgery. Identifying these patients using proper screening instrument is of great important clinical implications for the early detection, management, and reduction of the distress associated with head and neck cancer.

An improved colorimetric method for determination of cyanide content in bitter almond oil was developed. The optimal determination parameters were as follows: volume ratio of hydrochloric acid to bitter almond oil (v/v), 1.5:1; holding time for hydrolysis, 120 min; and volume ratio of distillation solution to bitter almond oil (v/v), 8:1. Analytical results showed that the relative standard deviations (SDs) of determinations were less than 10%, which satisfies the test requirements. The results of high-performance liquid chromatography and measurements exhibited a significant correlation (R = 0.9888, SD = 0.2015). Therefore, the improved colorimetric method can be used to determine cyanide content in bitter almond oil.

Indigenous children in Australia have higher dental caries levels than their non-Indigenous counterparts. Indigenous communities in South Australia's mid-north region have identified dental health as one of their top health priorities. In response to this, an oral health program based at the Pika Wiya Health Service in Port Augusta was established, with a dentist providing care for adults, and a dental therapist providing care for children, 2 days per week each. The purpose of this article is to compare the socio-demographic and oral health characteristics of children attending for care at the Pika Wiya Health Service Dental Clinic with those of their counterparts attending the general Port Augusta School Dental Service (SDS). Both Indigenous and non-Indigenous children were included. Data were obtained from the South Australian Dental Service (SADS), which routinely collects socio-demographic and dental information from patients seen through their system. Examinations were conducted by SADS-employed dental professionals. A full enumeration of children attending for care at Pika Wiya and the Port Augusta SDS from March 2001 to March 2006 was included. Surface level tooth data was captured using the EXACT treatment charting and management information system. The Socio-Economic Indices For Areas (SEIFA) were used to determine socio-economic status, and the dmft (sum of decayed, missing and filled teeth in the deciduous dentition) and DMFT (sum of decayed, missing and filled teeth in the permanent dentition) indices were used to assess oral health outcomes. Both measures were used for children aged 6-10 years because in such age groups children have a mixed dentition (both primary and permanent teeth are present). Caries prevalence (dmft/DMFT>0) and severity (mean dmft/DMFT) were calculated, as well as the Significant Caries Index (SiC) and Significant Caries Index 10 (SiC 10). The SiC is the mean dmft/DMFT of the one-third of the sample with the highest caries score; while the SiC 10 is the mean dmft/DMFT of the one-tenth of the sample with the highest caries score. In the 5 year observation period, 760 children were seen at the Pika Wiya Dental Service while over 6800 were seen at the Port Augusta SDS. A higher proportion of pre-school children attended for care at Pika Wiya, while proportionally more children aged > or = 11 years attended for care at the Port Augusta SDS. More females attended for care at Pika Wiya. Almost all children (99%) attending for care at Pika Wiya lived in the most disadvantaged areas according to the SEIFA scale. Children attending for care at Pika Wiya had three-times the mean number of decayed deciduous and permanent teeth than their counterparts attending the Port Augusta SDS. Over 75% of children attending for care at Pika Wiya aged 10 years or less had dental caries experience in the primary dentition compared with just over 50% of children attending for care at the Port Augusta SDS. Children attending for dental care at Pika Wiya aged 10 years or less had 1.8 times the mean dmft, 1.4 times the SiC and 1.4 times the Sic 10 of their counterparts attending for care at Port Augusta SDS. Over half the children aged > or = 6 years who attended Pika Wiya for dental care had caries experience in the permanent dentition compared with 38% of their Port Augusta SDS-attending counterparts. Children aged > or = 6 years who attended Pika Wiya for dental care had 1.9 times the mean DMFT, 1.8 times the SiC and 1.6 times the SiC 10 of their similarly-aged Port Augusta SDS-attending counterparts. Children attending for care at the Pika Wiya Dental Service were more likely to be pre-school-aged, female, Indigenous and living in a socially disadvantaged area, in comparison with children attending the Port Augusta SDS. Pika Wiya-attending children had 1.5-3 times the dental caries prevalence and severity in both the primary and permanent dentition of children attending for care at the Port Augusta SDS. The higher levels of dental caries experience, untreated disease and social disadvantage of children attending Pika Wiya provides further evidence for the need to address the health inequalities for Aboriginal children living in South Australia's mid-north region. While the Pika Wiya Oral Health Program is attempting to address some of these needs, a much broader focus to address the social and health inequalities will be required to improve the oral health characteristics of this population. It is hoped that through the Pika Wiya Dental Service's dedication to increasing Aboriginal child dental service participation rates, the proportion of untreated decay will diminish.

This study investigated whether patients who remain symptomatic more than a year following idiopathic facial paralysis gain benefit from tailored facial physiotherapy. A two-year retrospective review was conducted of all symptomatic patients. Data collected included: age, gender, duration of symptoms, Sunnybrook facial grading system scores pre-treatment and at last visit, and duration of treatment. The study comprised 22 patients (with a mean age of 50.5 years (range, 22-75 years)) who had been symptomatic for more than a year following idiopathic facial paralysis. The mean duration of symptoms was 45 months (range, 12-240 months). The mean duration of follow up was 10.4 months (range, 2-36 months). Prior to treatment, the mean Sunnybrook facial grading system score was 59 (standard deviation = 3.5); this had increased to 83 (standard deviation = 2.7) at the last visit, with an average improvement in score of 23 (standard deviation = 2.9). This increase was significant (p < 0.001). Tailored facial therapy can improve facial grading scores in patients who remain symptomatic for prolonged periods.

Is post-natal growth during the first 2 years of life in IVF singletons affected by type of medium used for culturing human embryos during an IVF treatment? The in vitro culture of human embryos in medium from Cook resulted in singletons with a lower weight during the first 2 years of life compared with singletons born after embryo culture in medium from Vitrolife. In a previous study, we reported that type of medium used for culturing human IVF embryos during the first few days after fertilization until fresh embryo transfer significantly affects fetal growth and consequently birthweight of the resulting singletons. From July 2003 to December 2006, a total of 1432 IVF treatment cycles with fresh embryo transfer were randomly allocated to have all embryos cultured in medium from Vitrolife AB (n = 715) or from Cook (n = 717). Two years after delivery, questionnaires were sent to the parents of all children requesting data about weight, height and head circumference around 1, 2, 3, 4, 6, 7.5, 9, 11, 14, 18 and 24 months of age. These measurements were collected as part of the children's health programme at municipal infant welfare centres in the Netherlands by health professionals unaware of this study. Patients requiring donor oocytes or applying for PGD were excluded from the study. From the 294 live born singletons that fulfilled our inclusion criteria, 29 were lost to follow-up. The remaining 265 singletons (Cook group: 117, Vitrolife group: 148) were included in the analysis. Data analysis included linear regression, to compare cross-sectionally weight standard deviation score (SDS), height SDS and head circumference, and the first order Berkey-Reed model for a longitudinal analysis of the growth data. Singletons in the Vitrolife group were heavier during the first 2 years of life compared with singletons in the Cook group. Cross-sectional analyses showed that adjusted weight SDS differed between groups at 1 (0.35 ± 0.14, P = 0.010), 2 (0.39 ± 0.14, P = 0.006), 3 (0.35 ± 0.14, P = 0.011), 4 (0.30 ± 0.13, P = 0.020), 11 (0.28 ± 0.13, P = 0.036), 14 (0.32 ± 0.13, P = 0.014) and 24 (0.39 ± 0.15, P = 0.011) months of age, while adjusted height SDS was only significantly different at 1 (0.21 ± 0.11, P = 0.048) month of age. Head circumference was similar between the two groups at all ages. Longitudinal analyses showed that both post-natal weight (P = 0.005) and height (P = 0.031) differed between the groups throughout the first 2 years of life, while the growth velocity was not significantly different between the two groups. Factors that might influence post-natal growth were included in the analysis; however, it was not possible to include all such factors, for example childhood diseases or nutrition, as this information was not available. The effect of culture medium during the first few days after fertilization on prenatal growth and birthweight persists during the first 2 years of life. This suggests that the human embryo is sensitive to its very early environment, and that the culture medium used in IVF may have lasting consequences. Further monitoring of the long-term growth, development and health of IVF children is therefore warranted. W.V. was funded with an unrestricted research grant from the Stichting Fertility Foundation.

Structural variation among genomes is now viewed to be as important as single nucleoid polymorphisms in influencing the phenotype and evolution of a species. Segmental duplication (SD) is defined as segments of DNA with homologous sequence. Here, we performed a systematic analysis of segmental duplications (SDs) among five lepidopteran reference genomes (Plutella xylostella, Danaus plexippus, Bombyx mori, Manduca sexta and Heliconius melpomene) to understand their potential impact on the evolution of these species. We find that the SDs content differed substantially among species, ranging from 1.2% of the genome in B. mori to 15.2% in H. melpomene. Most SDs formed very high identity (similarity higher than 90%) blocks but had very few large blocks. Comparative analysis showed that most of the SDs arose after the divergence of each linage and we found that P. xylostella and H. melpomene showed more duplications than other species, suggesting they might be able to tolerate extensive levels of variation in their genomes. Conserved ancestral and species specific SD events were assessed, revealing multiple examples of the gain, loss or maintenance of SDs over time. SDs content analysis showed that most of the genes embedded in SDs regions belonged to species-specific SDs ("Unique" SDs). Functional analysis of these genes suggested their potential roles in the lineage-specific evolution. SDs and flanking regions often contained transposable elements (TEs) and this association suggested some involvement in SDs formation. Further studies on comparison of gene expression level between SDs and non-SDs showed that the expression level of genes embedded in SDs was significantly lower, suggesting that structure changes in the genomes are involved in gene expression differences in species. The results showed that most of the SDs were "unique SDs", which originated after species formation. Functional analysis suggested that SDs might play different roles in different species. Our results provide a valuable resource beyond the genetic mutation to explore the genome structure for future Lepidoptera research.

To compare the accuracy (ie, precision and trueness) of full-arch impressions fabricated using either a conventional polyvinyl siloxane (PVS) material or one of two intraoral optical scanners. Full-arch impressions of a reference model were obtained using addition silicone impression material (Aquasil Ultra; Dentsply Caulk) and two optical scanners (Trios, 3Shape, and CEREC Omnicam, Sirona). Surface matching software (Geomagic Control, 3D Systems) was used to superimpose the scans within groups to determine the mean deviations in precision and trueness (μm) between the scans, which were calculated for each group and compared statistically using one-way analysis of variance with post hoc Bonferroni (trueness) and Games-Howell (precision) tests (IBM SPSS ver 24, IBM UK). Qualitative analysis was also carried out from three-dimensional maps of differences between scans. Means and standard deviations (SD) of deviations in precision for conventional, Trios, and Omnicam groups were 21.7 (± 5.4), 49.9 (± 18.3), and 36.5 (± 11.12) μm, respectively. Means and SDs for deviations in trueness were 24.3 (± 5.7), 87.1 (± 7.9), and 80.3 (± 12.1) μm, respectively. The conventional impression showed statistically significantly improved mean precision (P < .006) and mean trueness (P < .001) compared to both digital impression procedures. There were no statistically significant differences in precision (P = .153) or trueness (P = .757) between the digital impressions. The qualitative analysis revealed local deviations along the palatal surfaces of the molars and incisal edges of the anterior teeth of < 100 μm. Conventional full-arch PVS impressions exhibited improved mean accuracy compared to two direct optical scanners. No significant differences were found between the two digital impression methods.

Noonan-like syndrome with loose anagen hair (NS/LAH; OMIM 607721) is caused by a heterozygous c.4A>G mutation in SHOC2. Most cases exhibit both growth hormone deficiency (GHD) and growth hormone insensitivity (GHI) and thus require a high dose of growth hormone (GH) therapy (e.g., 35-40 µg/kg/day). We report on a genetically diagnosed NS/LAH patient manifesting severe short stature (-3.85 SDs) with low serum level of IGF1, 30 ng/ml. The peak levels of GH stimulation tests were within the normal range, and GHI was not observed in the IGF1 generation test. However, with low-dose GH therapy (25 µg/kg/day) for two years, IGF1 level and height were remarkably improved (IGF1: 117 ng/ml, height SDs: -2.20 SDs). Further, catch-up of motor development and improvement of the proportion of extending limbs to trunk were observed (the Developmental Quotient score increased from 68 to 98 points, and the relative sitting height ratio decreased from 0.62 to 0.57). Our results suggest that endocrinological causes for short stature are variable in NS/LAH and that GH therapy should be considered as a possible treatment for delayed development in NS/LAH. © 2015 Wiley Periodicals, Inc.

Context: Hypothalamic obesity, cardiovascular disease (CVD), and relapse/progression have a major impact on prognosis in childhood-onset craniopharyngioma (CP). We analyzed nuchal skinfold thickness (NST) on magnetic resonance imaging performed for follow-up monitoring as a novel parameter for body composition (BC) and CVD in CP. Objective: The objective of the study was to identify the association of NST with body mass index (BMI), waist to height ratio (WHtR), functional capacity, and blood pressure (BP) in CP and controls. Design: This was a cross-sectional and longitudinal prospective study in CP patients. Setting: The study was conducted at HIT-Endo, KRANIOPHARYNGEOM 2000/2007. Patients: Participants included 94 CP patients and 75 controls. Interventions: There were no interventions. Main Outcome Measures: Association of NST with BC and BP in 43 CP and 43 controls was measured. Results: NST correlated with BMI SD score (SDS; r = 0.78; P < .001; n = 169) and WHtR (r = 0.85; P < .001; n = 86) in the total cohort and CP patients (NST-BMI SDS: r = 0.77, P < .001, n = 94); NST-WHtR: r = 0.835, P < .001, n=43) and controls (NST-BMI SDS: r = 0.792, P < .001, n = 75; NST-WHtR: r = 0.671, P < .001, n = 43). In CP, systolic BP correlated with NST (r = 0.575, P < .001), BMI SDS (r = 0.434, P = .004), and WHtR (r = 0.386, P = .011). Similar results were observed for diastolic BP in CP. In multivariate analyses, NST had a predictive value for hypertension in postpubertal CP and controls (odds ratio 6.98, 95% confidence interval [1.65, 29.5], P = .008). During a longitudinal follow-up, changes in NST correlated with changes in BMI SDS (P < .001) and WHtR (P = .01) but not with changes in BP and functional capacity. Conclusions: Because monitoring of magnetic resonance imaging and BC is essential for follow-up in CP, NST could serve as a novel and clinically relevant parameter for longitudinal assessment of BC and CVD risk in CP.

Highlights: ► The basal spacing of MMT–CTAB–SDS reaches 5.30 nm. ► MMT–CTAB–SDS shows perfect dispersion property and excellent heat resistance. ► SDS helped to improve the heat resistance and decrease the surface energy of the MMT–CTAB–SDS particles. - Abstract: The synergistic effect of cationic surfactant (CTAB) and anionic surfactant (SDS) for the modification of Ca-montmorillonite (Ca-MMT) has been developed, and the novel cation–anion modified organomontmorillonite (MMT–CTAB–SDS) was prepared. X-ray diffraction (XRD) analysis indicates that the interlayer spacing of montmorillonite was well expanded by the intercalation of CTAB and SDS and the basal spacing increased from 1.54 nm (Ca-MMT) to 5.30more » nm (MMT–CTAB–SDS). Thermogravimetric analysis (TG) showed that the MMT–CTAB–SDS displayed excellent heat resistance. Scanning electron microscopy (SEM) analysis proved that the MMT–CTAB–SDS exhibited excellent dispersion property and the plates with few silicate layers can be observed. Contact angle tests indicated that the hydrophilicity of MMT–CTAB–SDS was lower than that of Ca-MMT and higher than that of MMT–CTAB. It was verified that SDS contributed to expanding the interlayer space, further improved the heat resistance of the MMT–CTAB and decreased the surface energy of the MMT–CTAB–SDS particles.« less

Associations between speech features and phenotypic severity in Treacher Collins syndrome

PubMed Central

2014-01-01

Background Treacher Collins syndrome (TCS, OMIM 154500) is a rare congenital disorder of craniofacial development. Characteristic hypoplastic malformations of the ears, zygomatic arch, mandible and pharynx have been described in detail. However, reports on the impact of these malformations on speech are few. Exploring speech features and investigating if speech function is related to phenotypic severity are essential for optimizing follow-up and treatment. Methods Articulation, nasal resonance, voice and intelligibility were examined in 19 individuals (5–74 years, median 34 years) divided into three groups comprising children 5–10 years (n = 4), adolescents 11–18 years (n = 4) and adults 29 years and older (n = 11). A speech composite score (0–6) was calculated to reflect the variability of speech deviations. TCS severity scores of phenotypic expression and total scores of Nordic Orofacial Test-Screening (NOT-S) measuring orofacial dysfunction were used in analyses of correlation with speech characteristics (speech composite scores). Results Children and adolescents presented with significantly higher speech composite scores (median 4, range 1–6) than adults (median 1, range 0–5). Nearly all children and adolescents (6/8) displayed speech deviations of articulation, nasal resonance and voice, while only three adults were identified with multiple speech aberrations. The variability of speech dysfunction in TCS was exhibited by individual combinations of speech deviations in 13/19 participants. The speech composite scores correlated with TCS severity scores and NOT-S total scores. Speech composite scores higher than 4 were associated with cleft palate. The percent of intelligible words in connected speech was significantly lower in children and adolescents (median 77%, range 31–99) than in adults (98%, range 93–100). Intelligibility of speech among the children was markedly inconsistent and clearly affecting the understandability. Conclusions Multiple speech deviations were identified in children, adolescents and a subgroup of adults with TCS. Only children displayed markedly reduced intelligibility. Speech was significantly correlated with phenotypic severity of TCS and orofacial dysfunction. Follow-up and treatment of speech should still be focused on young patients, but some adults with TCS seem to require continuing speech and language pathology services. PMID:24775909

A new, simple and rapid method for solid phase extraction and preconcentration of trace amounts of cadmium ions using 2-mercaptobenzothiazole/sodium dodecyl sulfate immobilized on magnetite nanoparticles (MBT-SDS-MNPs) was proposed. The method is based on the extraction of cadmium ions via complexation with MBT immobilized on SDS-coated MNPs and their determination by flame atomic absorption spectrometry. The effects of different parameters - pH; eluent type, concentration and volume; amounts of salt and adsorbent; contact time and interfering ions - on the adsorption of cadmium ions were studied. Under optimized conditions, the calibration curve was linear in the range of 10-5,000 μg L -1 . Detection limit and relative standard deviation of the proposed method were 0.009 μg L -1 and 2.2%, respectively. The adsorption data were analyzed by Langmuir and Freundlich isotherm models and a maximum adsorption amount of 24.80 mg g -1 , a Langmuir adsorption equilibrium constant (b) of 4.62 and Freundlich constants K f and n of 6.075 mg 1-1/n L 1/n g -1 and 2.391, respectively, were obtained. Finally, this adsorbent was successfully used for extraction of cadmium from water and food samples.

We reanalyzed previous experiments based on lexical-decision and reading-aloud tasks in children with dyslexia and control children and tested the prediction of the difference engine model (DEM) that mean condition reaction times (RTs) and standard deviations (SDs) would be linearly related (Myerson et al., 2003). Then we evaluated the slope and the intercept with the x-axis of these linear functions in comparison with previously reported values (i.e., slope of about 0.30 and intercept of about 300 ms). In the case of lexical decision, the parameters were close to these values; by contrast, in the case of reading aloud, a much steeper slope (0.66) and a greater intercept (482.6 ms) were found. Therefore, interindividual variability grows at a much faster rate as a function of condition difficulty for reading than for lexical-decision tasks (or for other tasks reported in the literature). According to the DEM, the slope of the regression that relates means and SDs indicates the degree of correlation among the durations of the stages of processing. We propose that the need for a close coupling between orthographic and phonological processing in reading is what drives the particularly strong relationship between performance and interindividual variability that we observed in reading tasks.

To assess the nutritional status in children with central nervous system (CNS) tumours, including concentration of leptin, the neuropeptide responsible for regulation of energetic homeostasis in an organism. The studied group comprised 44 children with brain tumours, aged (4.02-18.7). In all children during the whole therapy (from the start to the period of 1 year and more after the end of therapy), a number of standard deviations (SDs) for the body mass index (SDS BMI) was derived from anthropometric measurements. Concentrations of leptin were assayed simultaneously. The lowest values of the anthropometric indices were found in children during the maintenance therapy. Concentrations of leptin in patients with malignant CNS tumours and significant undernutrition were slightly greater as compared to patients presenting normal nutritional status; however, without statistical significance. In children with tumours of the central nervous system, there are quantitative disorders of the nutritional status which correlate with the period of the treatment. The most significant disorders in the nutritional status are observed during maintenance chemotherapy. There was no statistically significant correlation between the concentration of leptin and nutritional status in children with malignant brain tumours during the course of treatment and after its completion.

Aims: To investigate the relationship between socio-demographic factors and alcohol drinking patterns identified through a formal analysis of the factor structure of the Alcohol Use Disorders Identification Test (AUDIT) score in a population sample of working-age men in Russia. Methods: In 2008–2009, a sample of 1005 men aged 25–59 years living in Izhevsk, Russia were interviewed and information collected about socio-demographic circumstances. Responses to the AUDIT questions were obtained through a self-completed questionnaire. Latent dimensions of the AUDIT score were determined using confirmatory factor analysis and expressed as standard deviation (SD) units. Structural equation modelling was used to estimate the strength of association of these dimensions with socio-demographic variables. Results: The AUDIT was found to have a two-factor structure: alcohol consumption and alcohol-related problems. Both dimensions were higher in men who were unemployed seeking work compared with those in regular paid employment. For consumption, there was a difference of 0.59 SDs, (95% confidence interval (CI): 0.23, 0.88) and for alcohol-related problems one of 0.66 SD (95% CI: 0.31, 1.00). Alcohol-related problems were greater among less educated compared with more educated men (P-value for trend = 0.05), while consumption was not related to education. Similar results were found for associations with an amenity index based on car ownership and central heating. Neither dimension was associated with marital status. While we found evidence that the consumption component of AUDIT was underestimated, this did not appear to explain the associations of this dimension with socio-demographic factors. Conclusions: Education and amenity index, both measures of socio-economic position, were inversely associated with alcohol-related problems but not with consumption. This discordance suggests that self-reported questions on frequency and volume may be less sensitive markers of socio-economic variation in drinking than are questions about dependence and harm. Further investigation of the validity of the consumption component of AUDIT in Russia is warranted as it appears that the concept of a standard ‘drink’ as used in the instrument is not understood.

Disturbance of autonomic nervous activity has been thought to play a role in the climacteric symptoms of postmenopausal women. This study was therefore designed to investigate the relationship between autonomic nervous activity and climacteric symptoms in postmenopausal Japanese women. The autonomic nervous activity of 40 Japanese women with climacteric symptoms and 40 Japanese women without climacteric symptoms was measured by power spectral analysis of heart rate variability using a standard hexagonal radar chart. The scores for climacteric symptoms were determined using the simplified menopausal index. Sympathetic excitability and irritability, as well as the standard deviation of mean R-R intervals in supine position, were significantly (P < 0.01, 0.05, and 0.001, respectively) decreased in women with climacteric symptoms. There was a negative correlation between the standard deviation of mean R-R intervals in supine position and the simplified menopausal index score. The lack of control for potential confounding variables was a limitation of this study. In climacteric women, the standard deviation of mean R-R intervals in supine position is negatively correlated with the simplified menopausal index score.

To image SDS distribution across different skin regions, to compare the permeability difference between porcine and human skin, and to evaluate the interaction between SDS and skin. Full thickness porcine and human skin was treated with acyl chain perdeuterated SDS (SDS-d(25)) at room temperature and at 34 °C for 3, 24 and 40 h. SDS distribution in skin was monitored by confocal Raman and IR microspectroscopic imaging. Permeation profiles of SDS-d(25) in skin were derived from the band intensities of the CD(2) stretching vibrations. The interaction between SDS and skin was monitored through the CH(2) and CD(2) stretching frequencies and the Amide I and II spectral region. SDS-d(25) penetrates both porcine and human skin in a time and temperature-dependent manner, with slightly higher permeability through the stratum corneum (SC) in porcine skin. When SDS permeates into the SC, its chains are more ordered compared to SDS micelles. The secondary structure of keratin in the SC is not affected by SDS-d(25). The spatial distribution of SDS-d(25) in skin was obtained for the first time. Infrared microscopic imaging provides unique opportunities to measure concentration profiles of exogenous materials in skin and offers insights to interaction between permeants and skin.

To evaluate the reliability and validity of a Z-score normative EEG database for Low Resolution Electromagnetic Tomography (LORETA), EEG digital samples (2 second intervals sampled 128 Hz, 1 to 2 minutes eyes closed) were acquired from 106 normal subjects, and the cross-spectrum was computed and multiplied by the Key Institute's LORETA 2,394 gray matter pixel T Matrix. After a log10 transform or a Box-Cox transform the mean and standard deviation of the *.lor files were computed for each of the 2394 gray matter pixels, from 1 to 30 Hz, for each of the subjects. Tests of Gaussianity were computed in order to best approximate a normal distribution for each frequency and gray matter pixel. The relative sensitivity of a Z-score database was computed by measuring the approximation to a Gaussian distribution. The validity of the LORETA normative database was evaluated by the degree to which confirmed brain pathologies were localized using the LORETA normative database. Log10 and Box-Cox transforms approximated Gaussian distribution in the range of 95.64% to 99.75% accuracy. The percentage of normative Z-score values at 2 standard deviations ranged from 1.21% to 3.54%, and the percentage of Z-scores at 3 standard deviations ranged from 0% to 0.83%. Left temporal lobe epilepsy, right sensory motor hematoma and a right hemisphere stroke exhibited maximum Z-score deviations in the same locations as the pathologies. We conclude: (1) Adequate approximation to a Gaussian distribution can be achieved using LORETA by using a log10 transform or a Box-Cox transform and parametric statistics, (2) a Z-Score normative database is valid with adequate sensitivity when using LORETA, and (3) the Z-score LORETA normative database also consistently localized known pathologies to the expected Brodmann areas as an hypothesis test based on the surface EEG before computing LORETA.

Validation of 10-year SAO OMI ozone profile (PROFOZ) product using Aura MLS measurements

We validate the Ozone Monitoring Instrument (OMI) ozone profile (PROFOZ v0.9.3) product including ozone profiles between 0.22 and 261 hPa and stratospheric ozone columns (SOCs) down to 100, 215, and 261 hPa from October 2004 through December 2014 retrieved by the Smithsonian Astrophysical Observatory (SAO) algorithm against the latest Microwave Limb Sound (MLS) v4.2x data. We also evaluate the effects of OMI row anomaly (RA) on the retrieval by dividing the data set into before and after the occurrence of serious RA, i.e., pre-RA (2004-2008) and post-RA (2009-2014). During the pre-RA period, OMI ozone profiles agree very well with MLS data. After applying OMI averaging kernels to MLS data, the global mean biases (MBs) are within 3 % between 0.22 and 100 hPa, negative biases are within 3-9 % for lower layers, and the standard deviations (SDs) are 3.5-5 % from 1 to 40 hPa, 6-10 % for upper layers, and 5-20 % for lower layers. OMI shows biases dependent on latitude and solar zenith angle (SZA), but MBs and SDs are mostly within 10 % except for low and high altitudes of high latitudes and SZAs. Compared to the retrievals during the pre-RA period, OMI retrievals during the post-RA period degrade slightly between 5 and 261 hPa with MBs and SDs typically larger by 2-5 %, and degrade much more for pressure less than ˜ 5 hPa, with larger MBs by up to 8 % and SDs by up to 15 %, where the MBs are larger by 10-15 % south of 40° N due to the blockage effect of RA and smaller by 15-20 % north of 40° N due to the solar contamination effect of RA. The much worse comparisons at high altitudes indicate the UV1 channel of pixels that are not flagged as RA is still affected by the RA. During the pre-RA period, OMI SOCs show very good agreement with MLS data with global mean MBs within 0.6 % and SDs of 1.9 % for SOCs down to 215 and 261 hPa and of 2.30 % for SOC down to 100 hPa. Despite clearly worse ozone profile comparisons during the post-RA period, OMI SOCs only slightly degrade, with SDs larger by 0.4-0.6 % mostly due to looser spatial coincidence criteria as a result of missing data from RA and MBs larger by 0.4-0.7 %. Our retrieval comparisons indicate significant bias trends, especially during the post-RA period. The spatiotemporal variation of our retrieval performance suggests the need to improve OMI's radiometric calibration to maintain the long-term stability and spatial consistency of the PROFOZ product.

In repaired congenital heart disease, there is increasing evidence of sex differences in cardiac remodeling, but there is a lack of comparable data for specific congenital heart defects such as in repaired tetralogy of Fallot. In a prospective multicenter study, a cohort of 272 contemporary patients (158 men; mean age, 14.3±3.3 years [range, 8-20 years]) with repaired tetralogy of Fallot underwent cardiac magnetic resonance for ventricular function and metabolic exercise testing. All data were transformed to standard deviation scores according to the Lambda-Mu-Sigma method by relating individual values to their respective 50th percentile (standard deviation score, 0) in sex-specific healthy control subjects. No sex differences were observed in age at repair, type of repair conducted, or overall hemodynamic results. Relative to sex-specific controls, repaired tetralogy of Fallot in women had larger right ventricular end-systolic volumes (standard deviation scores: women, 4.35; men, 3.25; P=0.001), lower right ventricular ejection fraction (women, -2.83; men, -2.12; P=0.011), lower right ventricular muscle mass (women, 1.58; men 2.45; P=0.001), poorer peak oxygen uptake (women, -1.65; men, -1.14; P<0.001), higher VE/VCO2 (ventilation per unit of carbon dioxide production) slopes (women, 0.88; men 0.58; P=0.012), and reduced peak heart rate (women, -2.16; men -1.74; P=0.017). Left ventricular parameters did not differ between sexes. Relative to their respective sex-specific healthy control subjects, derived standard deviation scores in repaired tetralogy of Fallot suggest that women perform poorer than men in terms of right ventricular systolic function as tested by cardiac magnetic resonance and exercise capacity. This effect cannot be explained by selection bias. Further outcome data are required from longitudinal cohort studies.

Is the location of a septal deviation associated with the degree of postoperative pain after septoplasty?

The author conducted a prospective study of patients who underwent septoplasty for nasal obstruction secondary to a septal deviation to determine if the location of the deviation had any association with the degree of postoperative pain. Patients with an anteroposterior deviation were not included in this study, nor were patients with vasomotor rhinitis, allergic rhinitis, nasal polyposis, turbinate pathologies, or a systemic disease; also excluded were patients who were taking any medication and those who had undergone any previous nasal surgery. The final study population included 140 patients, who were divided into two groups on the basis of the location of their deviation. A total of 64 patients (35 men and 29 women; mean age: 29.8 yr) had an anterior deviation, and 76 patients (35 men and 41 women; mean age: 30.3 yr) had a posterior deviation; there were no statistically significant differences between the two groups in terms of sex (p = 0.309) or age (p = 0.848). During the postoperative period, pain intensity in both groups was self-evaluated on a visual analog scale on days 1, 3, and 7 and again at 3 and 6 months. The mean postoperative pain scores on days 1, 3, and 7 were significantly higher in the posterior deviation group than in the anterior group; scores in the two groups were similar at 3 and 6 months.

Childhood obesity is associated with several complications, including cardiovascular comorbidity. Several biomarkers, such as high-sensitive C-reactive protein (hs-CRP), proform of eosinophil major basic protein (Pro-MBP) and pregnancy associated plasma protein-A (PAPP-A), have equally been linked to increased cardiovascular susceptibility. This study investigates these biomarkers during weight loss and regain in obese children. A longitudinal study during a 12-week weight loss program with a 28 months follow-up was conducted. Anthropometrics and plasma concentrations of hs-CRP, Pro-MBP, and PAPP-A were measured at baseline; at days 14, 33 and 82 during weight loss; and at months 10, 16, and 28 during follow-up. Fifty-three boys and 62 girls aged 8-15 years with a median body mass index (BMI) standard deviation score (SDS) at baseline of 2.78 (boys), and 2.70 (girls) were included. Ninety children completed the weight loss program and 68 children entered the follow-up program. Pro-MBP and PAPP-A, but not hs-CRP, exhibited individual-specific levels (tracking) during weight loss and regain. The PAPP-A/Pro-MBP correlation was strong, whereas the hs-CRP/PAPP-A correlation was weak during weight fluctuations. Hs-CRP changes reflect weight changes. PAPP-A and Pro-MBP exhibited tracking during weight perturbations and may contribute as early risk markers of cardiovascular susceptibility.

Congenital hyperinsulinism (CHI), the commonest cause of persistent hypoglycaemia, has two main histological subtypes: diffuse and focal. Diffuse CHI, if medically unresponsive, is managed with near-total pancreatectomy. Post-pancreatectomy, in addition to persistent hypoglycaemia, there is a very high risk of diabetes mellitus and pancreatic exocrine insufficiency. International referral centre for the management of CHI. Medically unresponsive diffuse CHI patients managed with near-total pancreatectomy between 1994 and 2012. Near-total pancreatectomy. Persistent hypoglycaemia post near-total pancreatectomy, insulin-dependent diabetes mellitus, clinical and biochemical (faecal elastase 1) pancreatic exocrine insufficiency. Of more than 300 patients with CHI managed during this time period, 45 children had medically unresponsive diffuse disease and were managed with near-total pancreatectomy. After near-total pancreatectomy, 60% of children had persistent hypoglycaemia requiring medical interventions. The incidence of insulin dependent diabetes mellitus was 96% at 11 years after surgery. Thirty-two patients (72%) had biochemical evidence of severe pancreatic exocrine insufficiency (Faecal elastase 1<100 µg/g). Clinical exocrine insufficiency was observed in 22 (49%) patients. No statistically significant difference in weight and height standard deviation score (SDS) was found between untreated subclinical pancreatic exocrine insufficiency patients and treated clinical pancreatic exocrine insufficiency patients. The outcome of diffuse CHI patients after near-total pancreatectomy is very unsatisfactory. The incidence of persistent hypoglycaemia and insulin-dependent diabetes mellitus is very high. The presence of clinical rather than biochemical pancreatic exocrine insufficiency should inform decisions about pancreatic enzyme supplementation.

An increased relative risk of diabetes, ischemic heart disease, atherosclerosis, and hypertension have been reported in Turner syndrome (TS) patients. No data are currently available on the prevalence of metabolic syndrome in TS subjects. We evaluated the frequency of metabolic syndrome in obese and nonobese patients with TS. We evaluated 85 TS patients (27.05 ± 11.17 years). Obesity was defined as standard deviation score body mass index (SDS-BMI) ≥ 2 or BMI ≥ 30 kg/m(2) in adult patients. We classified metabolic syndrome according to the International Diabetes Federation (IDF). Hepatic ultrasound was performed in all girls. The prevalence of metabolic syndrome was 4.7% (12.5% obese and 4.3% nonobese, P=0.16) and associated with visceral adiposity (P=0.008). Abnormalities in glucose metabolism and hypertension were not associated with genetic or therapeutic factors. The karyotype 45,X was associated with atherogenic profile. Pathological waist circumference was more frequent in girls treated with estro-progestin (P=0.03). Evidence of fatty liver was associated with metabolic syndrome (P=0.03) and insulin resistance (P=0.05). Elevated liver enzymes were found in 15 subjects and were not related to treatment or ultrasound abnormalities. Prevalence of each component of metabolic syndrome in TS patients is partially influenced by genetic makeup and treatment. Hepatosteatosis was associated with metabolic syndrome and insulin resistance, but not to elevated liver enzymes.

Because schizophrenia is arguably among the most stigmatized health conditions, research assessing correlates of stigma is essential. This study examined factors associated with stigma in predominantly Protestant, low-income, urban African Americans in the Southeastern United States. A survey was distributed to 282 patrons of an inner-city food court/farmers' market. Associations were assessed between two measures of stigma--an adapted version of the Social Distance Scale (SDS) and a Semantic Differential Measure (SDM) of attributes such as dangerousness, dirtiness, and worthlessness--and several key variables addressing sociodemographic characteristics and exposure to/familiarity with mental illnesses. Independent predictors of scores on the two measures were identified using linear regression modeling. Higher stigma (as measured by the SDM) was predicted by a family history of psychiatric treatment, whereas lower stigma (as indicated by the SDS) was predicted by personal psychiatric treatment history and higher annual income. The results suggest special considerations when working with disenfranchised populations, especially family members of individuals with mental illnesses, in treatment settings.

To investigate the prevalence and possible influencing factors of depressive disorder in surgical inpatients. Two hundred and sixty-six surgical inpatients meeting the inclusion criteria were first screened with the self rating depression scale (SDS), and then the subjects screened positive and 20% of those screened negative were evaluated with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) as a gold standard for diagnosis of depressive disorder. Possible influencing factors were also analyzed by experienced psychiatrists. The standard score of SDS in the surgical inpatients were significantly higher than those in the Chinese norm, and the incidence of depressive disorder in the surgical inpatients was 37.2%. Unvaried analysis showed that depressive disorder were associated with gender, education, economic condition, variety of diseases, hospitalization duration, and treatment methods. Logistic regression analysis revealed that gender, economic condition, treatment methods and previous history were the main influencing factors. The incidence of depressive disorder in the surgical inpatients is high, and it is mainly influenced by gender, economic condition, treatment methods and previous history.

To compare the relative utility of GH stimulation tests and assays of spontaneous GH secretion as predictors of change in height standard deviation score at the end of GH treatment in children with short stature. We retrospectively studied 116 children (67 boys and 49 girls) with subnormal growth rates and short stature, defined as a height of more than 2SD below the mean for age and sex. The patients were classified according to their pattern of findings on baseline pharmacological GH stimulation tests and a 12-h assay of nocturnal spontaneous GH secretion. Twenty-eight patients (24%) had normal hormone levels by both methods (group I); 14 (12%) had normal levels by stimulation tests but subnormal levels by the physiological assay (group II); 48 (41%) had subnormal levels on pharmacological stimulation, with normal physiologic levels (group III); and 26 (22%) had subnormal levels by both methods (group IV). All children in groups II and IV, and 27 in group III, designated IIIb, were treated with recombinant GH at 0.7 U (0.23 mg/kg) of body weight per week. GH secretory patterns were related to final height SD scores and other growth parameters, after the patients had attained their adult stature 6.7 +/- 2.2 years (SD) after GH evaluation. The five groups were similar with respect to mean baseline height SD scores for chronological as well as bone age. Whether assessed as absolute or parentally adjusted (relative) values, mean gains in height SD scores were significantly greater in treated patients with physiological hormone deficiency (groups II and IV) than in those with normal hormone levels (group I, untreated controls). Relative height gains were 1.03 +/- 1.45 cm (6.6 +/- 9.28 cm) and 1.85 +/- 1.21 cm (SDS; 11.8 +/- 7.74 cm) in groups II and IV respectively, compared with only 0.11 +/- 0.42 cm (0.7 +/- 2.68 cm) in group I (P < 0.01 and P < 0.001). GH treatment failed to improve either the absolute or parentally adjusted final height of patients with GH deficiency by stimulation tests but normal levels by physiological assay. Long-term administration of GH to short children with normal spontaneous GH secretion is not associated with an appreciable increase in adult height.

Objectives Results of butanol threshold tests (BTTs) have shown that birhinal olfaction tends to converge toward monorhinal olfaction of the dominant nostril. However, birhinal olfaction may also be worse than dominant-side monorhinal olfaction. The goal of our study was to investigate the effect of deviated nasal septum on birhinal olfaction in patients with lateralized olfaction and to examine the effect of septoplasty in these patients. Methods A retrospective study with planned data collection was conducted in 518 patients who underwent BTTs. Lateralized olfaction was defined as monorhinal BTT scores that differed by >2 between sides. Underestimated birhinal olfaction was defined as a birhinal BTT score >2 lower than the dominant nostril monorhinal BTT score. Patients with lateralized olfaction were divided into 2 groups: group 1, underestimated birhinal olfaction; and group 2, without underestimated birhinal olfaction. Results Among 518 patients, 112 with lateralized olfaction were enrolled in this study. Group 1 included 23 patients (20.5%) and group 2 included 89 patients (79.5%). The severity of septal deviation (ratio of the distance of narrower side to wider side) did not differ between the 2 groups. Septal deviation to the dominant nostril was more common in group 1 than group 2 (73.9% vs. 37.6%; P=0.002). Five patients with septal deviation to the dominant nostril with underestimated birhinal olfaction underwent septoplasty. Improved lateralized olfaction occurred in all 5 patients postoperatively (P=0.041). Conclusion Septal deviation of the dominant nostril in patients with lateralized olfaction is associated with underestimated birhinal olfaction. Septoplasty may improve olfaction by increasing airflow in the dominant olfactory side. PMID:26976025

Purpose: Recent clinical outcome studies on prostate cancer have reported the influence of patient's obesity on the biochemical failure rates after various treatment modalities. In this study, we investigated the effect of patient's physical characteristics on prostate shift in external beam radiotherapy (EBRT) and hypothesized that there maybe a correlation between patient physique and tumor shift. Methods and Materials: A retrospective analysis was performed using data for 117 patients who received image-guided radiation therapy (IGRT) for prostate cancer between January 2005 and April 2007. A total of 1,465 CT scans were analyzed. The standard deviations (SDs) of prostate shifts formore » all patients, along with patient weight, body mass index (BMI), and subcutaneous adipose-tissue thickness (SAT), were determined. Spearman rank correlation analysis was performed. Results: Of the 117 patients, 26.5% were considered normal weight, 48.7% were overweight, 17.9% were mildly obese, and 6.9% were moderately to severely obese. Notably 1.3%, 1.5%, 2.0%, and 21.2% of the respective shifts were greater than 10 mm in the left-right (LR) direction for the four patient groups, whereas in the anterior-posterior direction the shifts are 18.2%, 12.6%, 6.7%, and 21.0%, respectively. Strong correlations were observed between SAT, BMI, patient weight, and SDs of daily shifts in the LR direction (p < 0.01). Conclusions: The strong correlation between obesity and shift indicates that without image-guided radiation therapy, the target volume (prostate with or without seminal vesicles) may not receive the intended dose for patients who are moderate to severely obese. This may explain the higher recurrence rate with conventional external beam radiation therapy.« less

Background Early detection of abnormal weight gain in childhood may be important for preventive purposes. It is still debated which annual changes in BMI should warrant attention. Aim To analyse 1-year increments of Body Mass Index (BMI) and standardised BMI (BMI SDS) in childhood and explore conditional change in BMI SDS as an alternative method to evaluate 1-year changes in BMI. Subjects and methods The distributions of 1-year increments of BMI (kg/m 2 ) and BMI SDS are summarised by percentiles. Differences according to sex, age, height, weight, initial BMI and weight status on the BMI and BMI SDS increments were assessed with multiple linear regression. Conditional change in BMI SDS was based on the correlation between annual BMI measurements converted to SDS. Results BMI increments depended significantly on sex, height, weight and initial BMI. Changes in BMI SDS depended significantly only on the initial BMI SDS. The distribution of conditional change in BMI SDS using a two-correlation model was close to normal (mean = 0.11, SD = 1.02, n = 1167), with 3.2% (2.3-4.4%) of the observations below -2 SD and 2.8% (2.0-4.0%) above +2 SD. Conclusion Conditional change in BMI SDS can be used to detect unexpected large changes in BMI SDS. Although this method requires the use of a computer, it may be clinically useful to detect aberrant weight development.

OBJECTIVE: To determine if gender is associated with diagnostic evaluation by primary care pediatricians caring for children with growth-faltering. PATIENTS AND METHODS: This was a retrospective study of children who were attending 4 urban pediatric primary care practices affiliated with a tertiary pediatric hospital. Growth-faltering was defined as height at the <5th percentile or a z-score decrease of ≥1.5 SDs before 18 months of age or ≥1 SD thereafter. For each child, height z score, age, gender, race, insurance, diagnostic tests, and subspecialist appointments were examined. RESULTS: Of 33 476 children, 3007 had growth-faltering (mean height: −1.5 ± 1.0 vs 0.3 ± 0.9 SDs in those without growth-faltering). Boys comprised 53% of the growth-faltering group (vs 51% of the nonfaltering group; P < .01). Among children with growth-faltering, 2.8% had endocrinology appointments (vs 0.8% of others; P < .0001) and 6% had gastroenterology appointments (vs 1.5% of others; P < .0001). Subspecialty care was not associated with gender. Pediatricians ordered diagnostic tests for a significantly greater proportion of children with growth-faltering than others. In multivariate analysis of height z score among children with growth-faltering, tests for chromosomes (1.4% of short girls vs 0.4% of short boys; P < .005) and growth hormone/insulin-like growth factor axis (0.9% of short girls vs 1.8% of short boys; P < .05) were associated with gender. Thirty-five percent of the girls for whom chromosome testing was performed were 12 years old or older. CONCLUSIONS: Patterns in diagnostic testing of children with growth-faltering by their pediatricians may lead to underdiagnosis of Turner syndrome and growth hormone deficiency among girls.

Body mass index (BMI) and waist circumference (WC) are widely used to predict % body fat (BF) and classify degrees of pediatric adiposity. However, both measures have limitations. The aim of this study was to evaluate whether a combination of WC and BMI would more accurately predict %BF than either alone. In a nationally representative sample of 2,303 6- to 13-year-old Swiss children, weight, height, and WC were measured, and %BF was determined from multiple skinfold thicknesses. Regression and receiver operating characteristic (ROC) curves were used to evaluate the combination of WC and BMI in predicting %BF against WC or BMI alone. An optimized composite score (CS) was generated. A quadratic polynomial combination of WC and BMI led to a better prediction of %BF (r (2) = 0.68) compared with the two measures alone (r (2) = 0.58-0.62). The areas under the ROC curve for the CS [0.6 * WC-SDS + 0.4 * BMI-SDS] ranged from 0.962 ± 0.0053 (overweight girls) to 0.982 ± 0.0046 (obese boys) and were somewhat greater than the AUCs for either BMI or WC alone. At a given specificity, the sensitivity of the prediction of overweight and obesity based on the CS was higher than that based on either WC or BMI alone, although the improvement was small. Both BMI and WC are good predictors of %BF in primary school children. However, a composite score incorporating both measures increased sensitivity at a constant specificity as compared to the individual measures. It may therefore be a useful tool for clinical and epidemiological studies of pediatric adiposity.

Background Vilazodone, a selective serotonin reuptake inhibitor and 5-HT1A receptor partial agonist, is approved for treating major depressive disorder in adults. This study (NCT01629966 ClinicalTrials.gov) evaluated the efficacy and safety of vilazodone in adults with generalized anxiety disorder (GAD). Methods A multicenter, double-blind, parallel-group, placebo-controlled, fixed-dose study in patients with GAD randomized (1:1:1) to placebo (n = 223), or vilazodone 20 mg/day (n = 230) or 40 mg/day (n = 227). Primary and secondary efficacy parameters were total score change from baseline to week 8 on the Hamilton Rating Scale for Anxiety (HAMA) and Sheehan Disability Scale (SDS), respectively, analyzed using a predefined mixed-effect model for repeated measures (MMRM). Safety outcomes were presented by descriptive statistics. Results The least squares mean difference (95% confidence interval) in HAMA total score change from baseline (MMRM) was statistically significant for vilazodone 40 mg/day versus placebo (–1.80 [–3.26, –0.34]; P = .0312 [adjusted for multiple comparisons]), but not for vilazodone 20 mg/day versus placebo. Mean change from baseline in SDS total score was not significantly different for either dose of vilazodone versus placebo when adjusted for multiplicity; significant improvement versus placebo was noted for vilazodone 40 mg/day without adjustment for multiplicity (P = .0349). The incidence of adverse events was similar for vilazodone 20 and 40 mg/day (∼71%) and slightly lower for placebo (62%). Nausea, diarrhea, dizziness, vomiting, and fatigue were reported in ≥5% of patients in either vilazodone group and at least twice the rate of placebo. Conclusions Vilazodone was effective in treating anxiety symptoms of GAD. No new safety concerns were identified. PMID:25891440

Base rates of low ANAM4 TBI-MIL scores were calculated in a convenience sample of 733 healthy male active duty soldiers using available military reference values for the following cutoffs: ≤2nd percentile (2 SDs), ≤5th percentile, <10th percentile, and <16th percentile (1 SD). Rates of low scores were also calculated in 56 active duty male soldiers who sustained an mTBI an average of 23 days (SD = 36.1) prior. 22.0% of the healthy sample and 51.8% of the mTBI sample had two or more scores below 1 SD (i.e., 16th percentile). 18.8% of the healthy sample and 44.6% of the mTBI sample had one or more scores ≤5th percentile. Rates of low scores in the healthy sample were influenced by cutoffs and race/ethnicity. Importantly, some healthy soldiers obtain at least one low score on ANAM4. These base rate analyses can improve the methodology for interpreting ANAM4 performance in clinical practice and research. © The Author 2014. Published by Oxford University Press.

Narita, M; Kurihara, T; Shindoh, T; Honda, M

1997-03-01

In order to clarify the characteristics of fatty acid metabolism in patients with myocardial infarction (MI), we performed myocardial imaging with 123I-beta-methyl-p-iodophenylpentadecanoic acid (BMIPP) and we compared these findings with exercise stress (Ex) and resting myocardial perfusion imaging with 99mTc-methoxyisobutylisonitrile (MIBI) and left ventricular wall motion index (WMI) which were obtained by left ventriculography. We studied 55 patients with MI, 14 patients with recent MI (RMI) and 41 patients with old MI (OMI), and myocardial images were divided into 17 segments and myocardial uptake of the radionuclide was graded from 0 (normal) to 3 (maximal abnormality). In 28 patients we compared segmental defect score (SDS) with WMI which were obtained by centerline method at the corresponded segments. As a whole, the mean total defect scores (TDSs) of BMIPP and Ex were similar and they were greater than the mean TDS of resting perfusion. In 30 patient (55%) TDS of BMIPP was greater than that of TDS of resting perfusion. In 24 patients perfusion abnormality developed by Ex and the location of BMIPP abnormality coincided with the abnormality of Ex. But in the other 6 patients Ex did not induce any abnormality and they were all RMI and infarcted coronary artery was patent. However in the group with TDS of BMIPP identical to TDS of resting perfusion (25 patients), 92% did not show myocardial perfusion abnormality after Ex. In the comparison of SDS and WMI, myocardial segments were divided into 3 groups; both SDSs of BMIPP and resting perfusion were normal or borderline abnormality (Group 1, 82 segments), SDS of resting perfusion was normal or borderline and SDS of BMIPP was definitely abnormal (Group 2, 10 segments) and both SDSs of BMIPP and resting perfusion were definitely abnormal (Group 3, 48 segments). In Group 1, WMS (-0.41 +/- 0.77) was significantly (p < 0.001) greater than those of Group 2 (-2.14 +/- 0.50) and Group 3 (-2.32 +/- 0.67). But there was no difference between Group 2 and 3. These findings suggested that in the segments with mismatch between BMIPP and resting perfusion reflects stunned myocardium. These results suggested that in half of the patients with MI, abnormal fatty acid metabolism may appear in viable myocardium such as jeopardized myocardium and myocardium which recently recovered from severe ischemia like acute MI and BMIPP imaging was useful to know the history of myocardial ischemia.

Using X-ray crystallography and isothermal titration calorimetry, we show that sodium dodecyl sulfate (SDS) binds specifically to a pre-formed internal cavity in horse-spleen apoferritin. Although sodium dodecyl sulfate (SDS) is widely used as an anionic detergent, it can also exert specific pharmacological effects that are independent of the surfactant properties of the molecule. However, structural details of how proteins recognize SDS are scarce. Here, it is demonstrated that SDS binds specifically to a naturally occurring four-helix bundle protein: horse apoferritin. The X-ray crystal structure of the apoferritin–SDS complex was determined at a resolution of 1.9 Å and revealed that themore » SDS binds in an internal cavity that has previously been shown to recognize various general anesthetics. A dissociation constant of 24 ± 9 µM at 293 K was determined by isothermal titration calorimetry. SDS binds in this cavity by bending its alkyl tail into a horseshoe shape; the charged SDS head group lies in the opening of the cavity at the protein surface. This crystal structure provides insights into the protein–SDS interactions that give rise to binding and may prove useful in the design of novel SDS-like ligands for some proteins.« less

2013-10-31

Large-scale scientific applications typically write their data to parallel file systems with organizations designed to achieve fast write speeds. Analysis tasks frequently read the data in a pattern that is different from the write pattern, and therefore experience poor I/O performance. In this paper, we introduce a prototype framework for bridging the performance gap between write and read stages of data access from parallel file systems. We call this framework Scientific Data Services, or SDS for short. This initial implementation of SDS focuses on reorganizing previously written files into data layouts that benefit read patterns, and transparently directs read callsmore » to the reorganized data. SDS follows a client-server architecture. The SDS Server manages partial or full replicas of reorganized datasets and serves SDS Clients' requests for data. The current version of the SDS client library supports HDF5 programming interface for reading data. The client library intercepts HDF5 calls and transparently redirects them to the reorganized data. The SDS client library also provides a querying interface for reading part of the data based on user-specified selective criteria. We describe the design and implementation of the SDS client-server architecture, and evaluate the response time of the SDS Server and the performance benefits of SDS.« less

Osteogenesis imperfecta (OI) is an inherited disorder characterized by bone fragility and low bone mass. Low bone density and fracture is a cause of morbidity. Limited data exists on bisphosphonate treatment in patients under 24 months of age. The objective of the study was to examine the safety and efficacy of pamidronate in children under 24 months with OI. To do so, we carried out a retrospective chart review and analysis of OI patients started on intravenous pamidronate under 24 months of age. Pamidronate was administered in three-day cycles. Growth, the number of fractures, and lumbar bone mineral densities were recorded both prior to and after treatment initiation. A total of 18 patients were reviewed. Five were classified as OI type I, seven were type III, and six were type IV. The mean age at treatment initiation was 12 months (range 11 days to 23 months). The mean lumbar z score at baseline was -3.63, which improved to -1.53 at one year (P < 0.01) and 0.79 (P < 0.01) at the end of the study. The fracture rate improved from 68 fractures in 209 months (0.32 fractures/patient-month) before treatment to 41 fractures in 1,248 months (0.03 fractures/patient-month) post-treatment (P < 0.05). Height standard deviation score (SDS) was conserved from baseline to end of study (-2.12 ± 2.45 vs. -2.45 ± 2.73) (P = 0.05) with an average follow-up of 73 months. The only adverse effect recorded in six infants was fever during the initial pamidronate infusion. Treatment with intravenous pamidronate is safe, significantly improves lumbar bone mineral density (L-BMD), and reduces fracture rates in young infants with OI while preserving linear growth.

Infants with Prader-Willi syndrome (PWS) typically display failure to thrive and decreased muscle mass with excess body fat for age. Growth hormone (GH) therapy in children with PWS improves, but does not normalize, body composition and muscle strength and agility. The objective of this study was to determine the effects of earlier GH therapy on anthropometric measurements, body composition, and psychomotor development in affected PWS infants and toddlers. Twenty-five subjects, ages 4-37 months, were randomized to 2 years of GH therapy (1 mg/m(2)/day) or 1 year of observation without GH treatment and then placed on GH (1.5 mg/m(2).day) for 1 year only. Anthropometric measurements were obtained by standard methods: percent body fat, lean body mass, and total body bone mineral density by dual x-ray absorptiometry; motor constructs of mobility and stability by the Toddler Infant Motor Evaluation; and cognitive and language function by the Capute Scales of Infant Language and Cognitive Development. GH-treated PWS subjects demonstrated normalization of length/height standard deviation scores (SDS), faster head growth, increased lean body mass accrual, and decreased percent body fat (P < 0.005 for all parameters), as well as improved language (P = 0.05) and cognitive (P = 0.02) quotient Z-scores compared with similarly aged untreated PWS subjects after 1 year into the study. PWS subjects treated before their first birthday spoke their first words at a mean age of 14.4 +/- 2.8 months and walked independently at 23.3 +/- 4.8 months. GH therapy was well-tolerated; however, one PWS subject experienced scoliosis progression. As greater benefits were seen in our study with early treatment, prompt referral to a pediatric endocrinologist for consideration of GH therapy is recommended for PWS at an early age.

Skeletal maturation determinations are usually reported as numeric data indicating accordance with chronologic age. However, significant changes in skeletal maturation can occur without falling outside two SDs. The purpose of our study was to design simple computer-generated sex-based charts to enhance the evaluation of skeletal maturation, especially when frequent assessments are made. The graphic representation of successive reports clearly depicts whether values retain their position in relation to the mean. In addition, the report includes computation of the exact SD score.

The true score measures the performance that is characteristic of the person tested; the variations, plus and minus, around the true score describe a characteristic of the test. When the standard deviation is used…

The accelerator hypothesis, which proposes a link between Type 1 diabetes (T1D) and Type 2 diabetes (T2D) through weight-related insulin resistance, remains untested in developing countries with increasing rates of childhood obesity and T1D, and different ethnicities. We aimed to test the accelerator hypothesis in the context of a significant increase in T1D at our centre. Medical records of children diagnosed with T1D between January 2005 and December 2014 were retrospectively reviewed. The body mass index (BMI) standard deviation scores (SDSs) were calculated using height and weight measurements recorded 1-2 months after diagnosis of T1D and compared with age-matched anthropometric data. The rate of change in BMI SDSs over time was calculated. Analysis of BMI data was undertaken for the three age categories: <5, 5 to <10 and >10 years. The mean age at diagnosis of 467 children with T1D was 7·27 ± 0·32 years and showed no change over the study period. There was a yearly increase of 14·11% in patient numbers; this increase was similar in the three age categories (22·7%, 17·0%, 16·3%, respectively, P = 1·0). Comparison of patient numbers between the two time periods of 5 years each showed a marked increase during 2010-2014 (148 vs 319, % increase 115·5%). The mean BMI SDSs at diagnosis in the three age categories were similar (P = 1·0) and showed a yearly change of -0·36; the mean change in the three age categories was also similar (-0·35, -0·27, -0·46, respectively, P = 1·0). No correlation was found between age at diagnosis and BMI SDSs (correlation coefficient 0·010, P = 0·82). The mean BMI SDS in patients was significantly lower compared to controls (-0·54 vs -0·02, P = 0·001). There was no association between BMI SDS and age at diagnosis in children with new onset T1D. Further studies are needed to test whether the accelerator hypothesis is relevant in developing countries. © 2015 John Wiley & Sons Ltd.

It was the goal of the trial to study the impact of electronic healthcare technology into treatment. One hundred and twenty-four children/adolescents (females 56%, age 13.5±2.8 years, height 1.64±0.13 m, weight 85.4±23.0 kg, body-mass index (BMI) 31.3±5.2 kg/m(2), BMI-standard deviation score (SDS) 2.50±0.5) were included. To assess physical activity and eating habits, a mobile motion sensor integrated into a mobile phone with digital camera was used. The children/adolescents had a significant weight reduction of 7.1±3.0 kg. BMI/BMI-SDS decreased (p<0.01). Intensity (14.1±6.4 activity units) and duration of physical activity (290.4±92.6 min/day) were assessed with sensors. Time walking: median 45.5 (range, 2.5-206.5), running 8.0 (range, 0-39.5), cycling 27.7 (range, 0-72.5), car driving 23.7 (range, 0-83.0) min/day. Comparing self-reported physical activity (walking 292.9 (range, 9.6-496.1), running 84.8 (range, 8.4-130.2) min/day) with assessment with sensors there were significant differences (p<0.01). Duration of physical activity documented by children/adolescents was higher than the assessment with motion sensors (walking 292.9 vs 45.5 min, p<0.01, running 84.8 vs 8.0 min, p<0.01). Sensor derived energy intake was higher than recommended (469.14±88.75 kcal vs 489.03±108.25 kcal, p=0.09). Performing multivariate analysis the following parameters showed associations with weight reduction (R-square=0.75): body weight (β=-0.95, p<0.01), C-reactive protein (CRP, β=0.15, p=0.07), physical activity, time spent in activities measured with sensors (β=-0.18, p=0.04), stress management (β=0.16, p=0.06), body fat mass at onset of the trial (β=0.45, p<0.01) and body shape (β=-0.25, p=0.01). The innovative mobile movement detection system is highly accepted by children and adolescents. The system is able to augment existing weight reduction and stabilization strategies.

The impact of high-intensity interval training (HIIT) as well as the association between the adipocyte fatty binding protein (aFABP) and cardiometabolic risk factors in overweight adolescents was investigated. Twenty-eight adolescents (13-18years; BMI≥90th percentile according to German reference values) were offered HIIT twice weekly for 6months. At baseline and after program completion, anthropometric, clinical and metabolic characteristics were assessed and a fasting blood sample was obtained. Leptin, adiponectin, visfatin and aFABP were measured using commercially available kits. DNA methylation at RALBP1 was assessed using pyrosequencing. Descriptive statistics, Pearson's correlation and linear models were calculated. Mean age at start of the program was 15.5±1.4years (53.5% females) and 20/28 (71%) provided follow-up data. At baseline, aFABP was correlated with BMI-SDS (0.48 [0.13,0.72]; p=0.0095), waist-to-height-ratio (0.63 [0.33,0.81], p=0.00036) and body fat content (0.55 [0.21, 0.77]; p=0.0031). Certain markers of metabolic risk were significantly correlated with aFABP (HOMA-IR 0.52 [0.19, 0.75], p=0.0044; γGT 0.48 [0.13, 0.73], p=0.0091; uric acid 0.46 [0.11, 0.71] p=0.013; HDL-C -0.39 [-0.66, -0.01] p=0.043; triglycerides 0.38 [0.01, 0.66], p=0.047). With the exception of triglycerides, these associations vanished after adjusting for BMI-SDS. aFABP did not depend on sex, age or pubertal stage in obese adolescents. After the HIIT program, small but significant reductions were observed in waist-to-height-ratio, (0.013 [0.0025, 0.024]; p=0.023), skin-fold based body fat content (2.0% [0.6, 3.5]; p=0.011), and standard deviation score of systolic blood pressure (0.69 [0.26 to 1.1]; p=0.0036). No changes were observed in adipokines or epigenetic markers following the program. HIIT may have beneficial effects on body composition and cardiometabolic health in overweight adolescents. Like in adults, aFABP seems to be associated with markers of metabolic risk in obese adolescents. Copyright © 2016 Elsevier Inc. All rights reserved.

To investigate response to growth hormone (GH) in the first, second and third years of treatment for all idiopathic GH-deficient (GHD) and idiopathic short stature (ISS) patients in Australia. Eligibility for subsidized GH treatment in Australia is determined on auxological criteria for the indication of Short Stature and Slow Growth (SSSG), which includes ISS (SSSG-ISS). The biochemical GHD (BGHD, peak GH < 10 mU/l) and SSSG indications are treated similarly: starting dose of 4·5 mg/m(2)/week with provision for incremental dosing. Some ISS patients were specifically diagnosed with familial short stature (SSSG-FSS). Responses for each year of treatment for BGHD, SSSG-ISS and SSSG-FSS cohorts were compared in relation to influencing variables and with international benchmarks. The effect of incremental dosing was assessed. Australian BGHD, SSSG-ISS and SSSG-FSS patients who had completed 1, 2, or 3 years of treatment and were currently receiving GH. Growth hormone dose, change in height-standard deviation score (ΔSDS) and growth velocity (GV). First-year response was 2-3 times greater than that in subsequent years: ΔSDS(1st year) = 0·92, 0·50 and 0·46 for BGHD, SSSG-ISS and SSSG-FSS, respectively. Responses were similar to international reports and inversely related to age at commencement of GH. First-year GV-for-age for BGHD patients was similar to international standards for idiopathic GHD. However, girls had an inferior response to boys when treatment commenced at <6 years of age. First-year GV-for-age for SSSG-ISS/FSS patients was less than ISS standards. Dose increments attenuated the first- to second-year decline in response to BGHD but marginally improved the responses for SSSG-ISS/FSS. The Australian auxology-based GH programme produces comparable responses to international programmes. A lower starting dose is offset by the initiation of treatment at younger ages. Incremental dosing does not appear optimal. A first-year dose of 6·4-6·9 mg/m(2)/week for GHD and 8·9 mg/m(2)/week for ISS with early commencement of GH treatment may be most efficacious. © 2012 Blackwell Publishing Ltd.

Cahill-Rowley, Katelyn; Rose, Jessica

2016-09-01

This research aims to develop a gait index for use in the pediatric clinic as well as research, that quantifies gait deviation in 18-22 month-old children: the Toddle Temporal-spatial Deviation Index (Toddle TDI). 81 preterm children (≤32 weeks) with very-low-birth-weights (≤1500g) and 42 full-term TD children aged 18-22 months, adjusted for prematurity, walked on a pressure-sensitive mat. Preterm children were administered the Bayley Scales of Infant Development-3rd Edition (BSID-III). Principle component analysis of TD children's temporal-spatial gait parameters quantified raw gait deviation from typical, normalized to an average(standard deviation) Toddle TDI score of 100(10), and calculated for all participants. The Toddle TDI was significantly lower for preterm versus TD children (86 vs. 100, p=0.003), and lower in preterm children with <85 vs. ≥85 BSID-III motor composite scores (66 vs. 89, p=0.004). The Toddle TDI, which by design plateaus at typical average (BSID-III gross motor 8-12), correlated with BSID-III gross motor (r=0.60, p<0.001) and not fine motor (r=0.08, p=0.65) in preterm children with gross motor scores ≤8, suggesting sensitivity to gross motor development. The Toddle TDI demonstrated sensitivity and specificity to gross motor function in very-low-birth-weight preterm children aged 18-22 months, and has been potential as an easily-administered, revealing clinical gait metric.

We have studied Sds22, a conserved regulator of protein phosphatase 1 (PP1) activity, and determined its role in modulating the activity of aurora B kinase and kinetochore–microtubule interactions. Sds22 is required for proper progression through mitosis and localization of PP1 to mitotic kinetochores. Depletion of Sds22 increases aurora B T-loop phosphorylation and the rate of recovery from monastrol arrest. Phospho–aurora B accumulates at kinetochores in Sds22-depleted cells juxtaposed to critical kinetochore substrates. Sds22 modulates sister kinetochore distance and the interaction between Hec1 and the microtubule lattice and, thus, the activation of the spindle assembly checkpoint. These results demonstrate that Sds22 specifically defines PP1 function and localization in mitosis. Sds22 regulates PP1 targeting to the kinetochore, accumulation of phospho–aurora B, and force generation at the kinetochore–microtubule interface. PMID:20921135

Sexual dimorphism in stature (SDS), jealousy and mate retention.

PubMed

Brewer, Gayle; Riley, Charlene

2010-10-02

Previous research has investigated the manner in which absolute height impacts on jealousy and mate retention. Although relative height is also important, little information exists about the potential influence of sexual dimorphism in stature (SDS) within established relationships. The current study investigated the relationship between SDS and the satisfaction, jealousy and mate retention behaviors reported by men and women. Heterosexual men (n = 98) and women (n = 102) completed a questionnaire. Men in high SDS relationships reported the lowest levels of cognitive and behavioral jealousy, although the impact of SDS on relationship satisfaction was less clear. SDS was not associated with the overall use of mate retention strategies; SDS did however affect the use of three specific strategies (vigilance, monopolization of time, love and care). SDS did not affect women's relationship satisfaction, jealousy (cognitive, behavioral, or emotional) or the use of mate retention strategies (with the exception of resource display).

Detecting epilepsy-related cognitive problems in clinically referred children with epilepsy: is the WISC-IV a useful tool?

The Wechsler Intelligence Scale for Children - Fourth Edition is the most widely used intelligence quotient (IQ) test in use today. However, despite numerous studies on IQ in childhood epilepsy, data exist almost exclusively from prior editions of the test, and no studies to date provide information on the sensitivity of specific WISC-IV scores (full-scale IQ [FSIQ], index, and subtest scores) to epilepsy-related cognitive impairments. The goal of this study was to determine the relative sensitivity of WISC-IV index and subscale scores in detecting cognitive problems in a group of clinically referred children with epilepsy compared to matched controls, and to define the relationship among WISC-IV scales, demographic factors, and epilepsy-related variables. WISC-IV data for children with epilepsy and high seizure burden were obtained from the Alberta Children's Hospital (ACH) and the New York University Comprehensive Epilepsy Center (NYU), two tertiary care medical centers for pediatric epilepsy. All children were clinically referred and received a standard assessment including WISC-IV. Matched controls were obtained from the WISC-IV Canadian and American standardization samples. WISC-IV scores from 212 children were included: 106 children with epilepsy (46 girls, 60 boys; mean age 11.0 years, standard deviation [SD] 3.1; parental education 14.5 years, SD 2.8), and 106 controls matched for age, gender, ethnicity, and parental education. Of the children with epilepsy, 44 had a clearly lateralized focus on electroencephalography (EEG) involving either the right or left hemisphere (26 left, 18 right). FSIQ for the epilepsy group was significantly lower than for controls, and 36.8% of children had IQs compatible with intellectual disability (FSIQ < 70), versus <1% of controls. In children with epilepsy, Working Memory and Processing Speed Index scores were lower than those for Verbal Comprehension and Perceptual Reasoning (p < 0.01). At the subtest level, scores for children with epilepsy were highest on visual and verbal subtests measuring reasoning skills such as Matrix Reasoning, and lowest on Coding (mean 5.93, SD 3.6). In terms of percentage of children on each subtest with low scores (i.e., scores below 2 SDs from the expected normative mean of 10), the Coding subtest identified the most children (28.3%) with low scores, and the Similarities subtest identified the fewest (16%). Later age at onset and shorter epilepsy duration were both correlated with higher WISC-IV FSIQ and index scores (r correlation coefficient values ranging from 0.36 to 0.44, p < 0.0001), and number of current and previous antiepileptic drug trials were both inversely correlated with FSIQ and index scores (r -0.27 to -0.47, all p-values < 0.01). Neither the FSIQ nor the index scores were significantly related to seizure frequency. A similar pattern was found for subtest scores. No differences in FSIQ, index scores, or subtest scores were found between children with left- and right-hemisphere seizure foci, or between those with positive or negative magnetic resonance imaging (MRI) findings. The WISC-IV is sensitive to epilepsy-related cognitive problems in clinically referred children with high seizure burden, particularly problems relating to expressive verbal, working memory, and processing speed difficulties. Compared to healthy children, these children have a very high rate of cognitive difficulties as assessed by the WISC-IV. The usefulness of the WISC-IV in detecting cognitive deficits in children with milder forms of epilepsy remains to be determined.

Many shape memory alloy (SMA)-based soft actuators have specific composite structures and manufacture processes, and are therefore unique. However, these exclusive characteristics limit their capabilities and applications, so in this article a soft and smart digital structure (SDS) is proposed that acts like a modular unit to assemble soft actuators by a layered adhesive bonding process. The SDS is a fully soft structure that encapsulates a digital skeleton consisting of four groups of parallel and independently actuated SMA wires capable of outputting a four-channel tunable force. The layered adhesive bonding process modularly bonds several SDSs with an elastic backbone to fabricate a layered soft actuator where the elastic backbone is used to recover the SDSs in a cooling process using the SMA wires. Two kinds of SDS-based soft actuators were modularly assembled, an actuator, SDS-I, with a two-dimensional reciprocal motion, and an actuator, SDS-II, capable of bi-directional reciprocal motion. The thermodynamics and phase transformation modeling of the SDS-based actuator were analyzed. Several extensional soft actuators were also assembled by bonding the SDS with an anomalous elastic backbone or modularly assembling the SDS-Is and SDS-IIs. These modularly assembled soft actuators delivered more output channels and a complicated motion, e.g., an actinomorphic soft actuator with four SDS-Is jumps in a series of hierarchical heights and directional movement by tuning the input channels of the SDSs. This result showed that the SDS can modularly assemble multifarious soft actuators with diverse capabilities, steerability and tunable outputs.

There are 2 methods commonly used for patient positioning in the anterior-posterior (A-P) direction: one is the skin mark patient setup method (SMPS) and the other is the couch height–based patient setup method (CHPS). This study compared the setup accuracy of these 2 methods for abdominal radiation therapy. The enrollment for this study comprised 23 patients with pancreatic cancer. For treatments (539 sessions), patients were set up by using isocenter skin marks and thereafter treatment couch was shifted so that the distance between the isocenter and the upper side of the treatment couch was equal to that indicated on themore » computed tomographic (CT) image. Setup deviation in the A-P direction for CHPS was measured by matching the spine of the digitally reconstructed radiograph (DRR) of a lateral beam at simulation with that of the corresponding time-integrated electronic portal image. For SMPS with no correction (SMPS/NC), setup deviation was calculated based on the couch-level difference between SMPS and CHPS. SMPS/NC was corrected using 2 off-line correction protocols: no action level (SMPS/NAL) and extended NAL (SMPS/eNAL) protocols. Margins to compensate for deviations were calculated using the Stroom formula. A-P deviation > 5 mm was observed in 17% of SMPS/NC, 4% of SMPS/NAL, and 4% of SMPS/eNAL sessions but only in one CHPS session. For SMPS/NC, 7 patients (30%) showed deviations at an increasing rate of > 0.1 mm/fraction, but for CHPS, no such trend was observed. The standard deviations (SDs) of systematic error (Σ) were 2.6, 1.4, 0.6, and 0.8 mm and the root mean squares of random error (σ) were 2.1, 2.6, 2.7, and 0.9 mm for SMPS/NC, SMPS/NAL, SMPS/eNAL, and CHPS, respectively. Margins to compensate for the deviations were wide for SMPS/NC (6.7 mm), smaller for SMPS/NAL (4.6 mm) and SMPS/eNAL (3.1 mm), and smallest for CHPS (2.2 mm). Achieving better setup with smaller margins, CHPS appears to be a reproducible method for abdominal patient setup.« less

The objective of this paper is to psychometrically validate the HIV Symptom Distress Scale (SDS), an instrument that can be used to measure overall HIV symptom distress or clinically relevant groups of HIV symptoms. A secondary data analysis was conducted using the Collaborations in HIV Outcomes Research U.S. Cohort (CHORUS). Inclusion criteria required study participants (N=5,521) to have a valid baseline measure of the AIDS Clinical Trial Group Symptom Distress Module, with an SF-12 or SF-36 completed on the same day. Psychometric testing assessed unidimensionality, internal consistency and factor structure using exploratory and confirmatory factor analysis, and structural equation modeling (SEM). Construct validity examined whether the new measure discriminates across clinical significance (CD4 and HIV viral load). Findings show that the SDS has high reliability (α=0.92), and SEM supports a correlated second-order factor model (physical and mental distress) with acceptable fit (GFI=0.88, AGFI=0.85, NFI=0.99, NNFI=0.99; RMSEA=0.06, [90% CI 0.06 – 0.06]; Satorra Bentler Scaled, C2 =3274.20; p=0.0). Construct validity shows significant differences across categories for HIV-1 viral load (p< 0.001) and CD4 (p< 0.001). Differences in mean SDS scores exist across gender (p< 0.001), race/ethnicity (p< 0.05) and educational attainment (p < 0.001). Hence, the HIV Symptom Distress Scale is a reliable and valid instrument, which measures overall HIV symptoms or clinically relevant groups of symptoms. PMID:22409246

Purpose: To evaluate the association between age-related macular degeneration (ARMD) and sensory neural hearing impairment (SHI). Methods: In this case-control study, hearing status of 46 consecutive patients with ARMD were compared with 46 age-matched cases without clinical ARMD as a control group. In all patients, retinal involvements were confirmed by clinical examination, fluorescein angiography (FA) and optical coherence tomography (OCT). All participants were examined with an otoscope and underwent audiological tests including pure tone audiometry (PTA), speech reception threshold (SRT), speech discrimination score (SDS), tympanometry, reflex tests and auditory brainstem response (ABR). Results: A significant (P = 0.009) association was present between ARMD, especially with exudative and choroidal neovascularization (CNV) components, and age-related hearing impairment primarily involving high frequencies. Patients had higher SRT and lower SDS against anticipated presbycusis than control subjects. Similar results were detected in exudative, CNV and scar patterns supporting an association between late ARMD with SRT and SDS abnormalities. ABR showed significantly prolonged wave I and IV latency times in ARMD (P = 0.034 and 0.022, respectively). Average latency periods for wave I in geographic atrophy (GA) and CNV, and that for wave IV in drusen patterns of ARMD were significantly higher than controls (P = 0.030, 0.007 and 0.050, respectively). Conclusion: The association between ARMD and age-related SHI may be attributed to common anatomical components such as melanin in these two sensory organs. PMID:27195086

The aim of the study was to correlate the clinical severity of pectus excavatum with its type and degree based on objective radiographic evaluation. Twelve brachycephalic dogs were included. Grading of the clinical severity was done based on a 6-point grading score. Thoracic radiographs were used to calculate the frontosagittal and vertebral indices at the tenth thoracic vertebra and the vertebra overlying the excavatum. Correlation between the clinical severity score and frontosagittal and vertebral indices was evaluated using Pearson's correlation coefficient. Typical pectus excavatum was recorded in the caudal sternum in seven dogs, with a mean clinical severity score of 1.7 ± 1.4, whereas in five dogs, atypical mid-sternal deviation was recorded with a mean clinical severity score of 3.8 ± 0.7. A strong correlation (r=0.7) was recorded between the clinical severity score and vertebral index in the atypical form, whereas a weak correlation (r=0.02) was recorded in the typical form (P<0.05). The clinical severity and degree of pectus excavatum was poorly correlated (r=0.3) in the typical form of pectus excavatum, whereas it was strongly correlated (r=0.9) in the atypical form. Pectus excavatum in dogs is associated with compressive cardiopulmonary dysfunction, which depends mainly on the site/type of deviation rather than the degree of deviation.

Congenital hypothyroidism (CH) is the most prevalent endocrinopathy resulting from thyroid hormones deficiency or lack of thyroid hormones (TH). Aim of the study is to evaluate the physical development of children with congenital hypothyroidism detected in screening tests, determine the effect of TSH level, thyroid hormones and perinatal, parental and environmental factors on the physical development of children. the study involved 79 children (47 girls, 32 boys) aged 3-18 years (mean age 7.3±3.5) with CH diagnosed in screening tests. Children's development was analysed in correlation with TSH value in the screening test, time of commencement of therapy with LT4, the initial dose of the LT4, mean TSH level in the first year of life, mean value of TSH and LT4 in the 2-year follow-up period, social origin, place of residence (village, city), parents': anthropometric parameters (BMI, height), age, level of education of the parents, which pregnancy it was, time of pregnancy. In children: body mass and length at birth, score on Apgar scale, additional chronic disease. Too low body mass was usually observed in the 2-4 month of life - 11.1%, while in the following months, the number of children with body mass below the 3 centile became lower. In children diagnosed with too low body mass <18 month of life, in the subsequent months was observed a normalisation. No correlation was between the body mass and TSH in infancy, the place of residence and level of education of the parents in all examined groups. According to Palczewska, BMI >97 centile occurred more often in the group of children with CH in the age range of 11 months - 6.9 years than in the control group, whereas ≥7 years obesity did not occur. The number of children with insufficient body length increased in the age groups: 11-18 months - 7.4%; 1.6-3.9 years - 7.9 % and 4-6.9 years - 9.1%. Children ≥7 years with height <3 centile were not observed. The number of children with height >97 centile in three age groups did not go beyond 4%. The biggest number of children >97 centile was noted in the age group 1.6-3.9 years (7.9%). Mean height SDS in all age groups was within the norm (±1 SDS for healthy population). 1. Physical development of children in infancy was in normal range. 2. Mean SDS of body mass in children was in the range of 1sds for healthy population in each age quarter. 3. Mean SDS for BMI in all age groups was above zero. 4. Mean SDS for body length in all age groups was in the range ±1 SDS for healthy population. 5. Early initiation of therapy HT is a prerequisite for proper physical development of children with congenital hypothyroidism.

pH-dependent differential interacting mechanisms of sodium dodecyl sulfate with bovine serum fetuin: a biophysical insight.

2014-11-20

Sodium dodecyl sulfate (SDS)-glycoprotein interaction serves as a model for a biological membrane. To get mechanistic insight into the interaction of SDS and glycoprotein, the effect of SDS on bovine serum fetuin (BSF) was studied in subcritical micellar concentrations at pH 7.4 and pH 2 using multiple approaches. SDS interacts electrostatically with BSF through its negatively charged head groups at pH 2 and hydrophobically via its alkyl chains at pH 7.4 up to a 1:20 molar ratio of BSF to SDS. However, at higher concentrations of SDS, BSF undergoes amyloid fibril formation at pH 2, as confirmed by enhanced ThT fluorescence, β-sheet formation, and TEM microscopy, whereas BSF undergoes induction of an α-helical structure in the presence of higher SDS concentration at pH 7.4. The increase in α-helical content with increasing SDS concentrations constrains the environment around tryptophan. As a consequence, the interconversion of tryptophan conformers decreases, resulting in a decrement of the fluorescence lifetime for BSF in the presence of SDS at pH 7.4.

Salt concentration governs nucleic acid hybridization according to the Schildkraut-Lifson equation. High concentrations of SDS are used in some common protocols, but the effects of SDS on hybridization stringency have not been reported. We investigated hybridization parameters in solutions containing SDS. With targets immobilized on nylon membranes and PCR- or transcription-generated probes, we report that the 50% dissociation temperature (Tm*) in the absence of SDS was 15 degrees C-17degrees C lower than the calculated Tm. SDS had only modest effects on Tm* [1% (w/v) equating to 8 mM NaCl]. RNA/DNA hybrids were approximately 11 degrees C more stable than DNA/DNA hybrids. Incomplete homology (69%) significantly reduced the Tm* for DNA/DNA hybrids (approximately /4degrees C; 0.45 degrees C/% nonhomology) but far less so for RNA/DNA hybrids (approximately 2.3 degrees C; approximately 0.07 degrees C/% non-homology); incomplete homology also markedly reduced the extent of hybridization. On these nylonfilters, SDS had a major effect on nonspecific binding. Buffers lacking SDS, or with low salt concentration, gave high hybridization backgrounds; buffers containing SDS, or high-salt buffers, gave reproducibly low backgrounds.

Our aim was to develop a portable quality control (QC) application using a thermometer, a barometer, an angle gauge, and a range finder implemented in a tablet-type consumer electronic device (CED) and to assess the accuracies of the measurements made. The QC application was programmed using Java and OpenCV libraries. First, temperature and atmospheric pressure were measured over 30 days using the temperature and pressure sensors of the CED and compared with those measured by a double-tube thermometer and a digital barometer. Second, the angle gauge was developed using the accelerometer of the CED. The roll and pitch angles of the CED were measured from 0 to 90° at intervals of 10° in the clockwise (CW) and counterclockwise (CCW) directions. The values were compared with those measured by a digital angle gauge. Third, a range finder was developed using the tablet's built-in camera and image-processing capacities. Surrogate markers were detected by the camera and their positions converted to actual positions using a homographic transformation method. Fiducial markers were placed on a treatment couch and moved 100 mm in 10-mm steps in both the lateral and longitudinal directions. The values were compared with those measured by the digital output of the treatment couch. The differences between CED values and those of other devices were compared by calculating means ± standard deviations (SDs). The means ± SDs of differences in temperature and atmospheric pressure were -0.07 ± 0.25°C and 0.05 ± 0.10 hPa, respectively. The means ± SDs of the difference in angle was -0.17 ± 0.87° (0.15 ± 0.23° degrees excluding the 90° angle). The means ± SDs of distances were 0.01 ± 0.07 mm in both the lateral and longitudinal directions. Our portable QC application was accurate and may be used instead of standard measuring devices. Our portable CED is efficient and simple when used in the field of medical physics. © 2018 American Association of Physicists in Medicine.

Untreated girls with Turner syndrome (TS) have short stature, relatively broad shoulders, a broad pelvis, short legs, a high fat mass and low muscle mass. Our objective was to assess the effect of the weak androgen oxandrolone (Ox) on body proportions and composition in growth hormone (GH)-treated girls with TS. 133 patients were included in a randomized, placebo-controlled, double-blind study. Patients were treated with GH (1.33 mg/m(2) per day) from baseline, combined with placebo (Pl) or Ox in a low (0.03 mg/kg per day) or previously conventional (0.06 mg/kg per day) dose from the age of eight, and oestrogens from the age of twelve. Sitting height, biacromial and biiliacal distances compared with height (i.e. shape values), BMI, waist circumference, sum of 4 skinfolds (sum4skin) and upper arm muscle area (UAMA) SD scores (SDS) were assessed half-yearly. Compared with GH + Pl, adult shape values on GH + Ox tended to be higher for sitting height (Ox 0.03, P = 0.2; Ox 0.06, P = 0.02) and biacromial distance (Ox 0.03, P = 0.2; Ox 0.06, P = 0.07) and lower for biiliacal distance (Ox 0.03, P = 0.004; Ox 0.06, P = 0.08). Sum4skin SDS tended to decrease more (Ox 0.03, P = 0.2; Ox 0.06, P = 0.005) while UAMA SDS increased more (Ox 0.03, P < 0.001; Ox 0.06, P < 0.001) than on GH + Pl. The increase in BMI and waist circumference SDS was comparable between the dosage groups. In GH-treated girls with TS, Ox 0.06 increases sitting height and tends to increase biacromial distance and decrease biiliacal distance, while Ox 0.03 significantly decreases biiliacal distance compared with height. Furthermore, Ox 0.06 reduces subcutaneous fat mass, and both Ox dosages increase muscle mass.

In fibrous dysplasia (BFD), normal bone and bone marrow are replaced by fibro-osseous tissue, leading to fracture, deformity and pain. BFD may be isolated, or in association with cutaneous hyperpigmentation and/or hyperfunctioning endocrinopathies, termed McCune-Albright syndrome (MAS). GH hypersecretion has been described in 10%-20% of MAS-BFD patients. Aim of the study was to determine the impact of GH-insulin like growth factor 1 (IGF1) axis hyperactivity on MAS-BFD morbidities and the efficacy of GH excess therapy. A multicentric cross-sectional analysis was conducted on three different MAS cohorts. From 195 MAS patients, 37 subjects (19%) with GH excess were identified and compared with 34 MAS controls without GH hypersecretion. Mean head circumference SDS was significantly higher in GH excess: 4.025 SDS vs 0.683 SDS (P < .0001). The risk of optic neuropathy (Odds ratio 4.231; P = .039), hearing deficit (Odds ratio 2.961; P = .0481), facial asymmetry (Odds ratio 6.563; P = .0192), malignancies (Odds ratio 15.24; P = .0173) were higher in GH excess group. Overall, pharmacotherapy (octreotide alone 10-30 mg/mo or with pegvisomant 10-20 mg/d) was effective in IGF1 normalization (IGF1 Z-score between -2 and +2 SDS) in 21/29 patients (72.4%) with good compliance to the regimen. Late diagnosis and GH excess treatment after 16 years old of age was associated with an increased risk of optic neuropathy (Odds ratio 4.500; P = .0491) and growth of pituitary adenomas (Odds ratio 7.846; P = .050). GH-IGF1 hyperactivity increases risk of morbidities in MAS. Medical therapy is effective in normalizing IGF1 in most patients, and early treatment during paediatric age is associated with a decreased risk of optic neuropathy and GH-secreting adenomas growth. © 2018 John Wiley & Sons Ltd.

Our objective was to summarize important advances in the management of children with idiopathic short stature (ISS). Participants were 32 invited leaders in the field. Evidence was obtained by extensive literature review and from clinical experience. Participants reviewed discussion summaries, voted, and reached a majority decision on each document section. ISS is defined auxologically by a height below -2 sd score (SDS) without findings of disease as evident by a complete evaluation by a pediatric endocrinologist including stimulated GH levels. Magnetic resonance imaging is not necessary in patients with ISS. ISS may be a risk factor for psychosocial problems, but true psychopathology is rare. In the United States and seven other countries, the regulatory authorities approved GH treatment (at doses up to 53 microg/kg.d) for children shorter than -2.25 SDS, whereas in other countries, lower cutoffs are proposed. Aromatase inhibition increases predicted adult height in males with ISS, but adult-height data are not available. Psychological counseling is worthwhile to consider instead of or as an adjunct to hormone treatment. The predicted height may be inaccurate and is not an absolute criterion for GH treatment decisions. The shorter the child, the more consideration should be given to GH. Successful first-year response to GH treatment includes an increase in height SDS of more than 0.3-0.5. The mean increase in adult height in children with ISS attributable to GH therapy (average duration of 4-7 yr) is 3.5-7.5 cm. Responses are highly variable. IGF-I levels may be helpful in assessing compliance and GH sensitivity; levels that are consistently elevated (>2.5 SDS) should prompt consideration of GH dose reduction. GH therapy for children with ISS has a similar safety profile to other GH indications.

Growth of short children in puberty is limited by the effect of estrogen on epiphyseal fusion. To compare: 1) the efficacy and safety of aromatase inhibitors (AIs) vs GH vs AI/GH on increasing adult height potential in pubertal boys with severe idiopathic short stature (ISS); and 2) differences in body composition among groups. Randomized three-arm open-label comparator. Outpatient clinical research. Seventy-six pubertal boys [mean (SE) age, 14.1 (0.1) years] with ISS [height SD score (SDS), -2.3 (0.0)]. Daily AIs (anastrozole or letrozole), GH, or AI/GH for 24-36 months. Anthropometry, bone ages, dual x-ray absorptiometry, spine x-rays, hormones, safety labs. Height gain [mean (SE)] at 24 months was: AI, +14.0 (0.8) cm; GH, +17.1 (0.9) cm; AI/GH, +18.9 (0.8) cm (P < .0006, analysis of covariance). Height SDS was: AI, -1.73 (0.12); GH, -1.43 (0.14); AI/GH, -1.25 (0.12) (P < .0012). Those treated through 36 months grew more. Regardless of treatment duration, height SDS at near-final height [n = 71; age, 17.4 (0.2) years; bone age, 15.3 (0.1) years; height achieved, ∼97.6%] was: AI, -1.4 (0.1); GH, -1.4 (0.2); AI/GH, -1.0 (0.1) (P = .06). Absolute height change was: AI, +18.2 (1.6) cm; GH, +20.6 (1.5) cm; AI/GH, +22.5 (1.4) cm (P = .01) (expected height gain at -2.0 height SDS, +13.0 cm). AI/GH had higher fat free mass accrual. Measures of bone health, safety labs, and adverse events were similar in all groups. Letrozole caused higher T and lower estradiol than anastrozole. Combination therapy with AI/GH increases height potential in pubertal boys with ISS more than GH and AI alone treated for 24-36 months with a strong safety profile.

The Gait Deviation Index summarizes overall gait 'quality', based on kinematic data from a 3-dimensional gait analysis. However, it is unknown which clinical outcomes may affect the Gait Deviation Index in patients with primary hip osteoarthritis. The aim of this study was to investigate associations between Gait Deviation Index as a measure of gait 'quality' and hip muscle strength and between Gait Deviation Index and patient-reported outcomes in patients with primary hip osteoarthritis. Forty-seven patients (34 males), aged 61.1 ± 6.7 years, with BMI 27.3 ± 3.4 (kg/m2) and with severe primary hip osteoarthritis underwent 3-dimensional gait analysis. Mean Gait Deviation Index, pain after walking and maximal isometric hip muscle strength (flexor, extensor, and abductor) were recorded. All patients completed the 'Physical Function Short-form of the Hip disability and Osteoarthritis Outcome Score (HOOS-Physical Function) and the Hip disability and Osteoarthritis Outcome Score subscales for pain (HOOS-Pain) and quality-of-life (HOOS-QOL). Mean Gait Deviation Index was positively associated with hip abduction strength (p<0.01, r = 0.40), hip flexion strength (p = 0.01, r = 0.37), HOOS-Physical Function (p<0.01, r = 0.41) HOOS-QOL (p<0.01, r = 0.41), and negatively associated with HOOS-Pain after walking (p<0.01, r = -0.45). Adjusting the analysis for walking speed did not affect the association. Patients with the strongest hip abductor and hip flexor muscles had the best gait 'quality'. Furthermore, patients with higher physical function, quality of life scores and lower pain levels demonstrated better gait 'quality'. These findings indicate that interventions aimed at improving hip muscle strength and pain management may to a moderate degree improve the overall gait 'quality' in patients with primary hip OA.

Objective: To conduct a post hoc evaluation of the prevalence of clinically significant pain and the efficacy of duloxetine in patients with generalized anxiety disorder (GAD) and concurrent pain. Method: Data from two 9- to 10-week double-blind, placebo-controlled, randomized clinical trials of duloxetine (60 to 120 mg) in DSM-IV–defined GAD were analyzed (study 1 was conducted from July 2004 to September 2005; study 2 was conducted from August 2004 to June 2005). Efficacy was assessed with the Hamilton Rating Scale for Anxiety (HAM-A), visual analog scales (VAS) for pain, the Hospital Anxiety Depression Scale (HADS), the Clinical Global Impressions-Improvement of Illness (CGI-I) scale, the Patient Global Impressions-Improvement (PGI-I) scale, and the Sheehan Disability Scale (SDS) global functional impairment scale. Results: Of 840 patients randomly assigned to treatment, 61.3% (302 duloxetine, 213 placebo) had VAS scores ≥ 30 mm on at least 1 of the pain scales, indicating clinically significant pain. Among those patients with concurrent pain at baseline, change from baseline to endpoint in the HAM-A total score (42.9% change in mean scores for duloxetine, 31.4% for placebo), HADS anxiety scale (40.3% vs. 22.8%), HADS depression scale (36.1% vs. 20.5%), HAM-A psychic factor (45.9% vs. 29.9%), and SDS global functional improvement score (45.5% vs. 22.1%) was significantly (all p's < .001) greater for duloxetine compared with placebo. Improvement on the CGI-I (p = .003) and PGI-I (p < .001) was also significantly greater for duloxetine. Response (HAM-A total score decrease ≥ 50%) (49% vs. 29%) and remission (HAM-A total score ≤ 7 at endpoint) (29% vs. 18%) rates were significantly greater for duloxetine compared with placebo (p < .001 and p = .041, respectively). Duloxetine demonstrated statistically significantly greater reduction in pain on all 6 VAS pain scales (all p's < .001 except headaches with p < .002) (for duloxetine, percent change in means from baseline to endpoint ranged from 40.1% to 45.2% across the 6 VAS scales; for placebo, 22.0% to 26.3%). Conclusion: Duloxetine, relative to placebo, improves anxiety symptoms, pain, and functional impairment among patients with GAD with concurrent clinically significant pain.

Accelerated SDS depletion from proteins by transmembrane electrophoresis: Impacts of Joule heating.

PubMed

Unterlander, Nicole; Doucette, Alan Austin

2018-02-08

SDS plays a key role in proteomics workflows, including protein extraction, solubilization and mass-based separations (e.g. SDS-PAGE, GELFrEE). However, SDS interferes with mass spectrometry and so it must be removed prior to analysis. We recently introduced an electrophoretic platform, termed transmembrane electrophoresis (TME), enabling extensive depletion of SDS from proteins in solution with exceptional protein yields. However, our prior TME runs required 1 h to complete, being limited by Joule heating which causes protein aggregation at higher operating currents. Here, we demonstrate effective strategies to maintain lower TME sample temperatures, permitting accelerated SDS depletion. Among these strategies, the use of a magnetic stir bar to continuously agitate a model protein system (BSA) allows SDS to be depleted below 100 ppm (>98% removal) within 10 min of TME operations, while maintaining exceptional protein recovery (>95%). Moreover, these modifications allow TME to operate without any user intervention, improving throughput and robustness of the approach. Through fits of our time-course SDS depletion curves to an exponential model, we calculate SDS depletion half-lives as low as 1.2 min. This promising electrophoretic platform should provide proteomics researchers with an effective purification strategy to enable MS characterization of SDS-containing proteins. © 2018 WILEY-VCH Verlag GmbH & Co.

A previous study, using capillary electrophoresis (CE), reported that six discrete complexes of ubiquitin (UBI) and sodium dodecyl sulfate (SDS) form at different concentrations of SDS along the pathway to unfolding of UBI in solutions of SDS. One complex (which formed between 0.8 and 1.8 mM SDS) consisted of native UBI associated with approximately 11 molecules of SDS. The current study used CE and 15N/13C-1H heteronuclear single quantum coherence (HSQC) NMR spectroscopy to identify residues in folded UBI that associate specifically with SDS at 0.8-1.8 mM SDS, and to correlate these associations with established biophysical and structural properties of this well-characterized protein. The ability of the surface charge and hydrophobicity of folded UBI to affect the association with SDS (at concentrations below the CMC) was studied, using CE, by converting lys-ε-NH3+ to lys-ε-NHCOCH3 groups. According to CE, the acetylation of lysine residues inhibited the binding of 11 SDS ([SDS] < 2 mM) and decreased the number of complexes of composition UBI-(NHAc)8·SDSn that formed on the pathway of unfolding of UBI-(NHAc)8 in SDS. A comparison of 15N-1H HSQC spectra at 0 mM and 1 mM SDS with calculated electrostatic surface potentials of folded UBI (e.g., solutions to the non-linear Poisson-Boltzmann (PB) equation) suggested, however, that SDS binds preferentially to native UBI at hydrophobic residues that are formally neutral (i.e., Leu and Ile), but that have positive electrostatic surface potential (as predicted from solutions to non-linear Poisson-Boltzmann equations); SDS did not uniformly interact with residues that have formal positive charge (e.g., Lys or Arg). Cationic functional groups, therefore, promote the binding of SDS to folded UBI because these groups exert long-range effects on the positive electrostatic surface potential (which extend beyond their own van der Waal’s radii, as predicted from PB theory), and not because cationic groups are necessarily the site of ionic interactions with sulfate groups. Moreover, SDS associated with residues in native UBI without regard to their location in α-helix or β-sheet structure (although residues in hydrogen-bonded loops did not bind SDS). No correlation was observed between the association of an amino acid with SDS and the solvent accessibility of the residue or its rate of amide H/D exchange. This study establishes a few (of perhaps several) factors that control the simultaneous molecular recognition of multiple anionic amphiphiles by a folded cytosolic protein. PMID:21939262

At low temperatures stability issues arise in commercial detergent products when surfactant crystallisation occurs, a process which is not currently well-understood. An understanding of the phase transition can be obtained using a simple binary SDS (sodium dodecyl sulfate) + DDAO (N,N-dimethyldodecylamine N-oxide) aqueous system. It expected that the crystallisation temperature of an SDS system can be lowered with addition of DDAO, thus providing a route to improve detergent stability. Detergent systems are typically comprised of anionic surfactants, non-ionic surfactants and water. This study explores the crystallisation of a three component system consisting of sodium dodecyl sulfate (SDS), N,N-dimethyldodecylamine N-oxide (DDAO), and water using wide-angle X-ray scattering (WAXS), differential scanning calorimetry (DSC) and confocal Raman microscopy. The presence of DDAO lowered the crystallisation temperature of a 20 wt% SDS system. For all aqueous mixtures of SDS + DDAO at low temperatures, SDS hydrated crystals, SDS.1/2H 2 O or SDS·H 2 O, formed. SDS hydrates comprising of layers of SDS separated by water layers. DDAO tended to reside in the vicinity of these SDS crystals. In the absence of DDAO an additional intermediary hydrate structure, SDS.1/8H 2 O, formed whereas for mixed SDS + DDAO systems no such structure was detected during crystallisation. Copyright © 2018.

Peptidoglycan sacculi with peptidoglycan-associated proteins were prepared from cell envelopes of Brucella abortus by extraction with sodium dodecyl sulfate (SDS) at 50 degrees C. On extraction of these preparations with SDS at 100 degrees C, a protein was obtained whose removal from peptidoglycan was confirmed by electron microscopy. Incubation of the 50 degrees C SDS-extracted cell envelopes with 50 mM MgCl2 in SDS-2-beta-mercaptoethanol at 37 degrees C also extracted the protein, along with lipopolysaccharide. At temperatures below 60 degrees C, the protein did not bind SDS strongly and had an apparent molecular weight greater than 92,000 in SDS-polyacrylamide gel electrophoresis. At higher temperatures, SDS bound strongly, and the apparent molecular weight was 38,000. Urea at 5 M did not alter the electrophoretic mobility of this 38,000-molecular-weight form. Immunoelectrophoresis in detergents with antisera to cell envelopes, carbohydrate staining of SDS-polyacrylamide gels, and production of anti-lipopolysaccharide antibodies by mice immunized with the purified protein indicated that lipopolysaccharide was present in free and protein-bound forms. Sequential gel filtration in SDS-EDTA and SDS-NaCl removed most lipopolysaccharide. After further purification by preparative SDS-polyacrylamide gel electrophoresis, a gas-liquid chromatographic analysis showed residual lipid tightly associated with the protein. The results suggested that the interactions between matrix proteins and other outer membrane components are stronger in B. abortus than in Escherichia coli, which was used as a control throughout.

Personal genome sequencing is increasingly utilized by healthy individuals for predispositional screening and other applications. However, little is known about the impact of 'genomic counseling' on informed decision-making in this context. Our primary aim was to compare measures of participants' informed decision-making before and after genomic counseling in the HealthSeq project, a longitudinal cohort study of individuals receiving personal results from whole genome sequencing (WGS). Our secondary aims were to assess the impact of the counseling on WGS knowledge and concerns, and to explore participants' satisfaction with the counseling. Questionnaires were administered to participants (n = 35) before and after their pre-test genomic counseling appointment. Informed decision-making was measured using the Decisional Conflict Scale (DCS) and the Satisfaction with Decision Scale (SDS). DCS scores decreased after genomic counseling (mean: 11.34 before vs. 5.94 after; z = -4.34, p < 0.001, r = 0.52), and SDS scores increased (mean: 27.91 vs. 29.06 respectively; z = 2.91, p = 0.004, r = 0.35). Satisfaction with counseling was high (mean (SD) = 26.91 (2.68), on a scale where 6 = low and 30 = high satisfaction). HealthSeq participants felt that their decision regarding receiving personal results from WGS was more informed after genomic counseling. Further research comparing the impact of different genomic counseling models is needed.

To examine whether the psychological benefits of sports activity differ between tetraplegics and paraplegics with spinal cord injury, and investigate the effect of frequency and modes of sports activity on the psychological benefits. The Self-rating Depression Scale (SDS), State-Trait Anxiety Inventory (STAI) and Profiles of Mood States (POMS) were administered to 169 male individuals with spinal cord injury (mean age=42.7 years) including 53 tetraplegics and 116 paraplegics. The subjects were divided into four groups according to their frequencies of sports activity; High-active (more than three times a week; n=32), Middle-active (once or twice a week, n=41), Low-active (once to three times a month, n=32), and Inactive (no sports participation, n=64). Analysis of variance revealed significant differences in depression for SDS, trait anxiety for STAI and depression and vigor for POMS among the groups. High-active group showed the lowest scores of depression and trait anxiety and the highest score of vigor among the four groups. In contrast, no significant difference was found for any psychological measurements between tetraplegics and paraplegics. In addition, there was no significant difference for any psychological measurements among modes (wheelchair basketball, wheelchair racing, wheelchair tennis and minor modes). These findings demonstrated that sports activity can improve the psychological status, irrespective of tetraplegics and paraplegics, and that the psychological benefits are emphasized by sports activity at high frequency.

Functional impairment related to painful physical symptoms in patients with generalized anxiety disorder with or without comorbid major depressive disorder: post hoc analysis of a cross-sectional study

PubMed Central

Background Generalized anxiety disorder (GAD) is the most frequent anxiety disorder in primary care patients. It is known that painful physical symptoms (PPS) are associated with GAD, regardless the presence of comorbid major depressive disorder (MDD). However the specific role of such symptoms in patients' functional impairment is not well understood. The objective of the present study is to assess functional impairment related to the presence of PPS in patients with GAD. Methods This is a post hoc analysis of a cross-sectional study. Functioning, in the presence (overall pain score >30; Visual Analog Scale) or absence of PPS, was assessed using the Sheehan Disability Scale (SDS) in three groups of patients; 1) GAD and comorbid MDD (GAD+MDD+), 2) GAD without comorbid MDD (GAD+MDD-), 3) controls (GAD-MDD-). ANCOVA models were used. Results Of those patients with GAD+MDD+ (n = 559), 436 (78.0%) had PPS, compared with GAD+MDD- (249 of 422, 59%) and controls (95 of 336, 28.3%). Functioning worsened in both GAD groups in presence of PPS (SDS least squares mean total score: 16.1 vs. 9.8, p < 0.0001, GAD+MDD+; 14.3 vs. 8.2, p < 0.0001, GAD+MDD-). The presence of PPS was significantly associated with less productivity. Conclusions Functional impairment related to the presence of PPS was relevant. Clinical implications should be considered.

Limited research has investigated disability and functional impairment in trichotillomania (TTM) subjects. This study examined the relationships between hair pulling (HP) style and severity and disability while controlling for mood severity. Disability was measured in individual life areas (work, social, and family/home life) instead of as a total disability score as in previous studies. One hundred fifty three adult hair pullers completed several structured interviews and self-report instruments. HP style and severity, as well as depression, anxiety, and stress were correlated with work, social, and family/home life impairment on the Sheehan Disability Scale (SDS). Multiple regression analyses were performed to determine significant predictors of life impairment. Depressive severity was a significant predictor for all SDS life areas. In addition, interference/avoidance associated with HP was a predictor for work and social life disability. Distress from HP was a significant predictor of social and family/home life disability. Focused HP score and anxiety were significant predictors of family/home life disability. As expected, depression in hair pullers predicted disability across life domains. Avoiding work and social situations can seriously impair functioning in those life domains. Severity of distress and worry about HP may be most elevated in social situations with friends and family and thus predict impairment in those areas. Finally, since HP often occurs at home, time spent in focused hair pulling would have a greater negative impact on family and home responsibilities than social and work life.

The influence of water-insoluble nonionic triblock copolymer PEO-PPO-PEO [poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)] i.e., E6P39E6 with molecular weight 2800, on the microstructure and self-aggregation dynamics of anionic surfactant sodium dodecylsulfate (SDS) in aqueous solution (D2O) were investigated using high resolution nuclear magnetic resonance (NMR) and small-angle neutron scattering (SANS) measurements. Variable concentration and temperature proton ((1)H), carbon ((13)C) NMR chemical shifts, (1)H self-diffusion coefficients, (1)H spin-lattice and spin-spin relaxation rates data indicate that the higher hydrophobic nature of copolymer significantly influenced aggregation characteristics of SDS. The salient features of the NMR investigations include (i) the onset of mixed micelles at lower SDS concentrations (<3 mM) relative to the copolymer-free case and their evolution into SDS free micelles at higher SDS concentrations (~30 mM), (ii) disintegration of copolymer-SDS mixed aggregate at moderate SDS concentrations (~10 mM) and still binding of a copolymer with SDS and (iii) preferential localization of the copolymer occurred at the SDS micelle surface. SANS investigations indicate prolate ellipsoidal shaped mixed aggregates with an increase in SDS aggregation number, while a contrasting behavior in the copolymer aggregation is observed. The aggregation features of SDS and the copolymer, the sizes of mixed aggregates and the degree of counterion dissociation (α) extracted from SANS data analysis corroborate reasonably well with those of (1)H NMR self-diffusion and sodium ((23)Na) spin-lattice relaxation data.

A novel staining method and the associated fluorescent dye were developed for protein analysis by capillary SDS-PAGE. The method strategy is to synthesize a pseudo-SDS dye and use it to replace some of the SDS in SDS–protein complexes so that the protein can be fluorescently detected. The pseudo-SDS dye consists of a long, straight alkyl chain connected to a negative charged fluorescent head and binds to proteins just as SDS. The number of dye molecules incorporated with a protein depends on the dye concentration relative to SDS in the sample solution, since SDS and dye bind to proteins competitively. In this work, we synthesized a series of pseudo-SDS dyes, and tested their performances for capillary SDS-PAGE. FT-16 (a fluorescein molecule linked with a hexadodecyl group) seemed to be the best among all the dyes tested. Although the numbers of dye molecules bound to proteins (and the fluorescence signals from these protein complexes) were maximized in the absence of SDS, high-quality separations were obtained when co-complexes of SDS–protein–dye were formed. The migration time correlates well with protein size even after some of the SDS in the SDS–protein complexes was replaced by the pseudo-SDS dye. Under optimized experimental conditions and using a laser-induced fluorescence detector, limits of detection of as low as 0.13 ng/mL (bovine serum albumin) and dynamic ranges over 5 orders of magnitude in which fluorescence response is proportional to the square root of analyte concentration were obtained. The method and dye were also tested for separations of real-world samples from E. coli. PMID:17874848

The strong and usually denaturing interaction between anionic surfactants (AS) and proteins/enzymes has both benefits and drawbacks: for example, it is put to good use in electrophoretic mass determinations but limits enzyme efficiency in detergent formulations. Therefore, studies of the interactions between proteins and AS as well as nonionic surfactants (NIS) are of both basic and applied relevance. The AS sodium dodecyl sulfate (SDS) denatures and unfolds globular proteins under most conditions. In contrast, NIS such as octaethylene glycol monododecyl ether (C 12 E 8 ) and dodecyl maltoside (DDM) protect bovine serum albumin (BSA) from unfolding in SDS. Membrane proteins denatured in SDS can also be refolded by addition of NIS. Here, we investigate whether globular proteins unfolded by SDS can be refolded upon addition of C 12 E 8 and DDM. Four proteins, BSA, α-lactalbumin (αLA), lysozyme, and β-lactoglobulin (βLG), were studied by small-angle x-ray scattering and both near- and far-UV circular dichroism. All proteins and their complexes with SDS were attempted to be refolded by the addition of C 12 E 8 , while DDM was additionally added to SDS-denatured αLA and βLG. Except for αLA, the proteins did not interact with NIS alone. For all proteins, the addition of NIS to the protein-SDS samples resulted in extraction of the SDS from the protein-SDS complexes and refolding of βLG, BSA, and lysozyme, while αLA changed to its NIS-bound state instead of the native state. We conclude that NIS competes with globular proteins for association with SDS, making it possible to release and refold SDS-denatured proteins by adding sufficient amounts of NIS, unless the protein also interacts with NIS alone.

Girls with Turner Syndrome (TS) treated or not treated with growth hormone (GH) are prone to overweight. Therefore, we hypothesize that puberty induction in TS is associated with weight gain. We analyzed weight changes (BMI-SDS) between onset of GH treatment and near adult height (NAH) in 887 girls with TS enrolled in KIGS (Pfizer International Growth Database). Puberty was induced with estrogens in 646 (72·8%) girls with TS. Weight status did not change significantly between GH treatment start and 1 year later (mean difference -0·02 BMI-SDS), but increased significantly (P < 0·001) until NAH (+0·40 BMI-SDS). The BMI-SDS increased +0·21 until start of puberty (P < 0·001). Girls with spontaneous and induced puberty showed similar BMI-SDS changes. Puberty induction at ≥12 years was associated with a significant (P < 0·001) less increase of BMI-SDS (+0·7 BMI-SDS) between baseline and NAH compared to puberty induction at <12 year (+1·0 BMI-SDS). In multiple linear regression analyses changes of BMI-SDS between baseline and NAH were negatively associated with baseline BMI-SDS (P < 0·001), GH doses (P = 0·015), and age at puberty induction (P < 0·001), positively with years on GH treatment (P = 0·004), while duration and dose of estrogens, its route of administration (transdermal/oral), changes of height-SDS, thyroxin and oxandrolone treatment, and karyotype did not correlate significantly to changes of BMI-SDS in this time period. Puberty does not seem to play a major role in weight gain in girls with TS since the majority of the increases in BMI-SDS occurred before puberty. However, late puberty induction seems to decrease the risk of weight gain. © 2016 John Wiley & Sons Ltd.

The present work was undertaken with a view to understand the influence of a model non-ionic tri-block copolymer PEO-PPO-PEO (poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)) with molecular weight 5800 i.e., P123 [(EO)(20)-(PO)(70)-(EO)(20)] on the self-aggregation characteristics of the anionic surfactant sodium dodecylsulfate (SDS) in aqueous solution (D(2)O) using NMR chemical shift, self-diffusion and nuclear spin-relaxation as suitable experimental probes. In addition, polymer diffusion has been monitored as a function of SDS concentration. The concentration-dependent chemical shift, diffusion data and relaxation data indicated the significant interaction of polymeric micelles with SDS monomers and micelles at lower and intermediate concentrations of SDS, whereas the weak interaction of the polymer with SDS micelles at higher concentrations of SDS. It has been observed that SDS starts aggregating on the polymer at a lower concentration i.e., critical aggregation concentration (cac=1.94 mM) compared to polymer-free situation, and the onset of secondary micelle concentration (C(2)=27.16 mM) points out the saturation of the 0.2 wt% polymer or free SDS monomers/micelles at higher concentrations of SDS. It has also been observed that the parameter cac is almost independent in the polymer concentrations of study. The TMS (tetramethylsilane) has been used as a solubilizate to measure the bound diffusion coefficient of SDS-polymer mixed system. The self-diffusion data were analyzed using two-site exchange model and the obtained information on aggregation dynamics was commensurate with that inferred from chemical shift and relaxation data. The information on slow motions of polymer-SDS system was also extracted using spin-spin and spin-lattice relaxation rate measurements. The relaxation data points out the disintegration of polymer network at higher concentrations of SDS. The present NMR investigations have been well corroborated by surface tension and conductivity measurements. Copyright © 2011 Elsevier Inc. All rights reserved.

Perceptions of past, present, and future events may be related to stress pathophysiology. We assessed whether Time Perspective (TP) is associated with cortisol dynamics among healthy adults (N=61, Ages=18-35, M=22.9, SD=4.1) exposed to the Trier Social Stress Test (TSST). TP was measured according to two profiles: maladaptive Deviation from Balanced TP (DBTP) and adaptive Deviation from Negative TP (DNTP). Eight salivary cortisol samples were analyzed using area under the curve with respect to ground (AUCg) and to increase (AUCi). Statistic analyses involved partial correlations controlling for depressive symptoms. Results for both sexes showed that higher DBTP scores were associated with lower cortisol AUCg scores, while higher DNTP scores were associated with higher cortisol AUCg scores. These novel findings suggest that maladaptive TP profiles influence hypocortisolism, whereas adaptive TP profiles influence hypercortisolism. Thus, TP profiles may impact conditions characterized by altered cortisol concentrations. Published by Elsevier B.V.

Integral membrane proteins are notoriously difficult to identify and analyze by mass spectrometry because of their low abundance and limited number of trypsin cleavage sites. Our strategy to address this problem is based on a novel technology for MALDI-MS peptide sample preparation that increases the success rate of membrane protein identification by increasing the sensitivity of the MALDI-TOF system. For this, we used sample plates with predeposited matrix spots of CHCA crystals prepared by vacuum sublimation onto an extremely low wettable (ultraphobic) surface. In experiments using standard peptides, an up to 10-fold gain of sensitivity was found for on-chip preparations compared with classical dried-droplet preparations on a steel target. In order to assess the performance of the chips with membrane proteins, three model proteins (bacteriorhodopsin, subunit IV(a) of ATP synthase, and the cp47 subunit from photosystem II) were analyzed. To mimic realistic analysis conditions, purified proteins were separated by SDS-PAGE and digested with trypsin. The digest MALDI samples were prepared either by dried-droplet technique on steel plates using CHCA as matrix, or applied directly onto the matrix spots of the chip surface. Significantly higher signal-to-noise ratios were observed for all of the spectra resulting from on-chip preparations of different peptides. In a second series of experiments, the membrane proteome of Rhodococcus jostii RHA1 was investigated by AIEC/SDS-PAGE in combination with MALDI-TOF MS/MS. As in the first experiments, Coomassie-stained SDS-PAGE bands were digested and the two different preparation methods were compared. For preparations on the Mass·Spec·Turbo Chip, 43 of 60 proteins were identified, whereas only 30 proteins were reliably identified after classical sample preparation. Comparison of the obtained Mascot scores, which reflect the confidence level of the protein identifications, revealed that for 70% of the identified proteins, higher scores were obtained by on-chip sample preparation. Typically, this gain was a consequence of higher sequence coverage due to increased sensitivity. PMID:19137096

The purpose of this study was to evaluate the setup uncertainties for single-fraction stereotactic radiosurgery (SF-SRS) based on clinical data with two different mask-creation methods using pretreatment con-beam computed tomography imaging guidance. Dedicated frameless fixation Brain- LAB masks for 23 patients were created as a routine mask (R-mask) making method, as explained in the BrainLAB's user manual. Alternative masks (A-masks), which were created by modifying the cover range of the R-masks for the patient's head, were used for 23 patients. The systematic errors including these for each mask and stereotactic target localizer were analyzed, and the errors were calculated as the means ± standard deviations (SD) from the left-right (LR), superior-inferior (SI), anterior-posterior (AP), and yaw setup corrections. In addition, the frequencies of the threedimensional (3D) vector length were analyzed. The values of the mean setup corrections for the R-mask in all directions were < 0.7 mm and < 0.1°, whereas the magnitudes of the SDs were relatively large compared to the mean values. In contrast, the means and SDs of the A-mask were smaller than those for the R-mask with the exception of the SD in the AP direction. The means and SDs in the yaw rotational direction for the R-mask and the A-mask system were comparable. 3D vector shifts of larger magnitude occurred more frequently for the R-mask than the A-mask. The setup uncertainties for each mask with the stereotactic localizing system had an asymmetric offset towards the positive AP direction. The A-mask-creation method, which is capable of covering the top of the patient's head, is superior to that for the R-mask, so the use of the A-mask is encouraged for SF-SRS to reduce the setup uncertainties. Moreover, careful mask-making is required to prevent possible setup uncertainties.

N -lined glycosylation is one of the critical quality attributes (CQA) for biotherapeutics impacting the safety and activity of drug product. Changes in pattern and level of glycosylation can significantly alter the intrinsic properties of the product and, therefore, have to be monitored throughout its lifecycle. Therefore fast, precise, and unbiased N -glycan mapping assay is desired. To ensure these qualities, using analytical methods that evaluate completeness of deglycosylation is necessary. For quantification of deglycosylation yield, methods such as reduced liquid chromatography-mass spectrometry (LC-MS) and reduced capillary gel electrophoresis (CGE) have been commonly used. Here we present development of two additional methods to evaluate deglycosylation yield: one based on LC using reverse phase (RP) column and one based on reduced sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE gel) with offline software (GelAnalyzer). With the advent of rapid deglycosylation workflows in the market for N -glycan profiling replacing overnight incubation, we have aimed to quantify the level of deglycosylation in a selected rapid deglycosylation workflow. Our results have shown well resolved peaks of glycosylated and deglycosylated protein species with RP-LC method allowing simple quantification of deglycosylation yield of protein with high confidence. Additionally a good correlation, ≥0.94, was found between deglycosylation yields estimated by RP-LC method and that of reduced SDS-PAGE gel method with offline software. Evaluation of rapid deglycosylation protocol from GlycanAssure™ HyPerformance assay kit performed on fetuin and RNase B has shown complete deglycosylation within the recommended protocol time when evaluated with these techniques. Using this kit, N -glycans from NIST mAb were prepared in 1.4 hr and analyzed by hydrophilic interaction chromatography (HILIC) ultrahigh performance LC (UHPLC) equipped with a fluorescence detector (FLD). 37 peaks were resolved with good resolution. Excellent sample preparation repeatability was found with relative standard deviation (RSD) of <5% for peaks with >0.5% relative area.

To examine the definition of sarcopenia in Chinese subjects by relating the value of appendicular skeletal muscle mass (ASM) divided by height squared to physical functional outcomes after 4 years. Four-year prospective study. A Chinese community in Hong Kong SAR China. Three thousand one hundred fifty-three community-living men and women aged 65 and older. Information collected by questionnaire included demographics, health limitation on activities of daily living (ADLs), self-care, physical activity level, dietary intake, and psychosocial functioning. Measurements included height, weight, grip strength, step length in a 6-minute walk, and body composition. Four-year outcomes for those with ASM in kg per height in meters squared (ASM/ht(2)) less than 2 standard deviations (SDs) and 2 SDs or more below the young adult mean value were compared using analysis of variance and logistic regression, adjusting for potential confounding factors such as age, fat mass, presence or absence of malnutrition, dietary protein and vitamin D intake, comorbidity, and cognitive impairment. Participants with ASM/ht(2) 2 SDs or more below the young adult mean had lower grip strength and greater limitation in climbing stairs and general ADLs after adjusting for confounding factors. A U-shaped relationship was observed between physical limitation and ASM/ht(2), with increasing physical limitation below or above a range of 7.25 to 6.75 kg/m(2) in men and 6.00 to 6.25 kg/m(2) in women. Values of 5.25 to 6.74 kg/m(2) in women were associated with approximately 30% less risk of functional limitation after 5 years. No clear cutoff was found in men. Sarcopenia may be defined in terms of a range of values for ASM/ht(2) associated with the lowest risk of future physical limitations. The importance of establishing a quantitative value for the definition of sarcopenia may facilitate future interventional studies using pharmacological or nonpharmacological strategies.

Chemical applicability domain of the Local Lymph Node Assay (LLNA) for skin sensitisation potency. Part 2. The biological variability of the murine Local Lymph Node Assay (LLNA) for skin sensitisation.

The Local Lymph Node Assay (LLNA) is the most common in vivo regulatory toxicology test for skin sensitisation, quantifying potency as the EC3, the concentration of chemical giving a threefold increase in thymidine uptake in the local lymph node. Existing LLNA data can, along with clinical data, provide useful comparator information on the potency of sensitisers. Understanding of the biological variability of data from LLNA studies is important for those developing non-animal based risk assessment approaches for skin allergy. Here an existing set of 94 EC3 values for 12 chemicals, all tested at least three times in the same vehicle have been analysed by calculating standard deviations (SD) for logEC3 values. The SDs range from 0.08 to 0.22. The overall SD for the 94 logEC3 values is 0.147. Thus the 95% confidence limits (2xSD) for LLNA EC3 values are within a factor of 2, comparable to those for physico-chemical measurements such as partition coefficients and solubility. The residual SDs of Quantitative Mechanistic Models (QMMs) based on physical organic chemistry parameters are similar to the overall SD of the LLNA, indicating that QMMs of this type are unlikely to be bettered for predictive accuracy.

2016-10-03

Mathematics professional development is widely offered, typically with the goal of improving teachers' content knowledge, the quality of teaching, and ultimately students' achievement. Recently, new assessments focused on mathematical knowledge for teaching (MKT) have been developed to assist in the evaluation and improvement of mathematics professional development. This study presents empirical estimates of average program change in MKT and its variation with the goal of supporting the design of experimental trials that are adequately powered to detect a specified program effect. The study drew on a large database representing five different assessments of MKT and collectively 326 professional development programs and 9,365 teachers. Results from cross-classified hierarchical growth models found that standardized average change estimates across the five assessments ranged from a low of 0.16 standard deviations (SDs) to a high of 0.26 SDs. Power analyses using the estimated pre- and posttest change estimates indicated that hundreds of teachers are needed to detect changes in knowledge at the lower end of the distribution. Even studies powered to detect effects at the higher end of the distribution will require substantial resources to conduct rigorous experimental trials. Empirical benchmarks that describe average program change and its variation provide a useful preliminary resource for interpreting the relative magnitude of effect sizes associated with professional development programs and for designing adequately powered trials. © The Author(s) 2016.

Present article reviews solid dispersion (SD) technologies and other patented inventions in the area of pharmaceutical SDs, which provide stable amorphous SDs. The review briefly compiles different techniques for preparing SDs, their applications, characterization of SDs, types of SDs and also elaborates the carriers used to prepare SDs. The advantages of recently introduced SD technologies such as RightSize(™), closed-cycle spray drying (CSD), Lidose® are summarized. Stability-related issues like phase separation, re-crystallization and methods to curb these problems are also discussed. A patented carrier-screening tool for predicting physical stability of SDs on the basis of drug-carrier interaction is explained. Applications of SD technique in controlled drug delivery systems and cosmetics are explored. Review also summarizes the carriers such as Soluplus®, Neusilin®, Solumer(TM) used to prepare stable amorphous SD. Binary and ternary SDs are found to be more stable and provide better enhancement of solubility or dissolution of poorly water-soluble drugs. The use of surfactants in the carrier system of SD is a recent trend. Surfactants and polymers provide stability against re-crystallization of SDs, surfactants also improve solubility and dissolution of drug.

Benzalkonium chloride neutralizes the irritant effect of sodium dodecyl sulfate.

When benzalkonium chloride (BKC), a cationic surfactant, is added to sodium dodecyl sulfate (SDS), an anionic surfactant, and used in patch testing, on the basis of their known physicochemical interaction, it is possible to predict that there will be a tendency towards a reduction in the expected irritant response when compared to SDS alone. The aim of this study was to investigate whether BKC could reduce the irritant response to SDS when applied after the SDS exposure. 54 non-atopic adult volunteers were recruited for the study. 20% SDS was applied for 2 h under occlusion. 1% BKC was then applied to the same site. Various controls, including SDS application followed by water for 2 h, were included. The irritant reaction was assessed at 24 h and 48 h. 40 of the 54 subjects had some reaction when SDS was applied for 2 h followed by either benzalkonium chloride or water control under occlusion. In comparison to water control, where BKC was applied after SDS, 20 of the 40 responders had a weaker reaction but only 4 had a stronger response. This study shows that BKC applied to skin exposed to SDS attenuates the resulting irritant reaction.

In orthodontics, facial esthetics is assumed to be related to golden proportions apparent in the ideal human face. The aim of the study was to analyze the putative relationship between facial esthetics and golden proportions in white adolescents. Seventy-six adult laypeople evaluated sets of photographs of 64 adolescents on a visual analog scale (VAS) from 0 to 100. The facial esthetic value of each subject was calculated as a mean VAS score. Three observers recorded the position of 13 facial landmarks included in 19 putative golden proportions, based on the golden proportions as defined by Ricketts. The proportions and each proportion's deviation from the golden target (1.618) were calculated. This deviation was then related to the VAS scores. Only 4 of the 19 proportions had a significant negative correlation with the VAS scores, indicating that beautiful faces showed less deviation from the golden standard than less beautiful faces. Together, these variables explained only 16% of the variance. Few golden proportions have a significant relationship with facial esthetics in adolescents. The explained variance of these variables is too small to be of clinical importance.

The authors conducted a population-based study to attempt to estimate the effect of human immunodeficiency virus type 1 (HIV-1) seropositivity on Armed Services Vocational Aptitude Battery test scores in otherwise healthy individuals with early HIV-1 infection. The Armed Services Vocational Aptitude Battery is a 10-test written multiple aptitude battery administered to all civilian applicants for military enlistment prior to serologic screening for HIV-1 antibodies. A total of 975,489 induction testing records containing both Armed Services Vocational Aptitude Battery and HIV-1 results from October 1985 through March 1987 were examined. An analysis data set (n = 7,698) was constructed by choosing five controls for each of the 1,283 HIV-1-positive cases, matched on five-digit ZIP code, and a multiple linear regression analysis was performed to control for demographic and other factors that might influence test scores. Years of education was the strongest predictor of test scores, raising an applicant's score on a composite test nearly 0.16 standard deviation per year. The HIV-1-positive effect on the composite score was -0.09 standard deviation (99% confidence interval -0.17 to -0.02). Separate regressions on each component test within the battery showed HIV-1 effects between -0.39 and +0.06 standard deviation. The two Armed Services Vocational Aptitude Battery component tests felt a priori to be the most sensitive to HIV-1-positive status showed the least decrease with seropositivity. Much of the variability in test scores was not predicted by either HIV-1 serostatus or the demographic and other factors included in the model. There appeared to be little evidence of a strong HIV-1 effect.

Resistance of bromelain to SDS binding.

2009-04-01

Interaction of the plant cysteine protease bromelain with SDS has been studied using CD spectroscopy, intrinsic fluorescence emission, extrinsic fluorescence probe pyrene, isothermal calorimetric (ITC) investigations and inhibition of hydrolyzing activity. Results exhibit number of synchronous transitions when plotted against the total SDS concentration. SDS at submicellar level caused conformation change of bromelain leading to a stable entity. ITC and pyrene experiments suggest that the structural modifications below 5 mM, the cmc(app) of SDS solutions containing bromelain, are the result of alterations of solvent hydrophobicity or non-specific weak binding and/or adsorption of SDS monomers. Melting temperature (T(m)) and the free energy change for thermal unfolding (DeltaG(unf)) of the SDS induced conformers was decreased by 5 degrees C and 0.5 kcal/mol respectively, compared to native bromelain. Below 5 mM, SDS caused large decrease in V(max) without affecting K(m) for the substrate Z-Arg-Arg-NHMec. Analysis of kinetic data imply that SDS acts as a partial non-competitive inhibitor since even at 100 mM, the residual activity of bromelain was retained by 3%. Inhibition studies show an IC(50) of 0.55 mM and a high K(i) of 0.145 mM. These demonstrate that bromelain is resistant to SDS binding and denaturation, a property known for beta-sheet rich kinetically stable proteins.

Behavior of Amiloride (AMI) as a metal ion sensor in anionic surfactant assemblies of varying concentrations at different pH is depicted in this work. From a non-sensor fluorophore, AMI has been transformed in to a tunable fluorosensor for Cu2 + ions in various SDS concentrations. At premicellar concentration of SDS, ion-pair complex is expected to be formed between AMI and SDS due to electrostatic interactions between them. However at CMC concentrations of SDS, fluorescence intensity of AMI is greatly enhanced with red shift in emission, due to the incorporation of AMI molecule in the hydrophobic micellar interface. The behavior of metal sensing by AMI-SDS assemblies gives rise to several interesting observations. Micellation of SDS has been greatly enhanced by increasing copper ion concentrations, as these counter ions screens the charge on monomers of SDS which lead to the aggregation at premicellar concentrations only. Concentrations and pH dependent discrete trends of interactions between SDS-AMI and SDS-Cu2 + ions, have given tunable fluorescence responses (fluorescence turn on/turn off) of AMI for added Cu2 + ions. The electrostatic interaction between the metal cations and the anionic surfactants is the driving force for bringing the metal ions near to the vicinity of micelle where AMI resides. Thus, a comprehensive understanding of the mechanism related to the 'turn on-turn off' fluorescence response of AMI with respect to pH and SDS concentration for effective Cu2 + ion sensing is illustrated in this work.

One hundred female cats undergoing routine ovariohysterectomy under midazolam-medetomidine-ketamine anaesthesia were included in a blinded, randomised, prospective clinical study to compare postoperative analgesia produced by four analgesic drug combinations given preoperatively (n = 25 per group). A secondary aim was to assess the effects in kittens and pregnant animals. Buprenorphine 180 µg/m(2) or butorphanol 6 mg/m(2) were given with either carprofen 4 mg/kg (groups BUPC and BUTC, respectively) or meloxicam 0.3 mg/kg (groups BUPM or BUTM, respectively). Medetomidine was not antagonised. A simple, descriptive scale (SDS; 0-4), a dynamic and interactive visual analogue scale (DIVAS; 0-100 mm) and mechanical nociceptive thresholds (MT; 2.5-mm diameter probe) were used to evaluate postoperative pain. All pain scores were low (DIVAS <10 mm, SDS <2 and MT >10 N) and there were no significant differences between the groups. It was concluded that all protocols provided adequate analgesia and when used with midazolam-medetomidine-ketamine are effective for routine feline ovariohysterectomy.

Though Science Data System (SDS) development has not traditionally been part of the mission concept phase, lessons learned and study of past Earth science missions indicate that SDS functionality can greatly benefit algorithm developers in all mission phases. We have proposed a SDS approach for the SMAP Mission that incorporates early support for an algorithm testbed, allowing scientists to develop codes and seamlessly integrate them into the operational SDS. This approach will greatly reduce both the costs and risks involved in algorithm transitioning and SDS development.

To determine levels of professionalism in undergraduate medical students at a private medical college and assess how changes emerge during their training. The study was conducted at Aga Khan University, a tertiary care teaching hospital, during November and December 2011. Freshmen, Year 3 and Year 5 students were requested to fill out a questionnaire. It was designed to assess the participants' levels of professionalism and how they perceived the professional environment around them by incorporating previously described scales. The questionnaire was re-validated on a random sample of practising clinicians at the same hospital. SPSS 17 was used for statistical analysis. The study sample comprised 204 participants. The mean score for level of individual professionalism was 7.72+/-3.43. Only 13 (6.4%) students had a score one standard deviation above the faculty mean. About 24 (11.8%) were one standard deviation and 35 (17.2%) were 2 standard deviations below the faculty mean. The remaining 130 (63.7%) were >2 standard deviations below the faculty mean. Considering the level of education, the mean score for level of professionalism was 8.00+/-3.39 for freshmen, 6.85+/-3.41 for year 3 students, and 8.40+/-3.34 for year 5 students. The currently employed teaching practices inculcating the values of professionalism in medical students are serving as a buffer to maintain the pre-training levels of professionalism from declining.

Stimulant-associated growth deficits in children with attention deficit hyperactivity disorder (ADHD) have long been a concern. We chose 146 school age children diagnosed with ADHD being treated with methylphenidate (MPH) and 29 drug-free ADHD children, and followed them up for 2-4 years. We recorded the changes in height and weight after long-term methylphenidate treatment and analyzed the influence of confounding factors to growth in height, weight, and height velocity. The change of the gap between patients' height and mean height in the methylphenidate group was -1.86+/-0.82 cm ( P<0.001); in controls it was -0.26+/-0.51 cm ( P<0.05). The changes of height standard deviation score (SDS) in the methylphenidate group and controls were -0.14+/-0.23 SD ( P<0.001) and +0.05+/-0.10 SD ( P<0.05), respectively. The differences between the 2 groups were significant ( P<0.001). Both correlation and regression analyses indicated that the duration of treatment contributed significantly to the variance in change of height ( P<0.001). The height velocity was significantly attenuated in the first year. The change of the gap between the patients' weight and weight for height after methylphenidate was -0.14+/-1.25 kg ( P>0.05). From this study, a small but significant deceleration of height velocity has been identified as a long-term side effect of methylphenidate, the magnitude of the height deficit is related to the duration of treatment. Methylphenidate had no significant influence on weight and BMI values. Georg Thieme Verlag KG Stuttgart.New York.

A "nested" case-control design was used to identify cases from a longitudinally followed cohort of 1236 newborns registered during 1984-1987, living in three socioeconomically different areas. The children had a length <-2SDS (standard deviation scores) at 6, 12, 24 and 60 mo of age using the NCHS reference. The controls were matched for gender, area and month of birth. A logistic regression analysis was used for determining the risk factors for stunting at each age. Postnatal linear growth was also examined in these two groups of children and body size was compared with the NCHS reference and that of upper-middle-class children (n = 240). At 6 mo of age, prematurity and duration of breastfeeding showed a significant association with stunting. At 12 mo, maternal height, birthweight and stunting at 6 mo, while at 24 mo, stunting at 6, 12 and 18 mo were identified as important factors. At 60 mo, no other factors besides previous stunting could be identified. The mean height reached at 60 mo showed a deficit of 6 and 13 cm for the controls and the cases, respectively, compared to the NCHS reference. Twenty-eight percent of the children from the two poor areas who were stunted at 6 mo had improved by 60 mo of age. The risk factors for stunting varied at different ages, relating more to feeding at early ages and to previous stunting, predominantly at higher ages. The linear growth showed that faltering increased with age when cases and controls were treated separately. Recovery from stunting could also be demonstrated.

Knowledge concerning energy metabolism in Turner syndrome (TS) is lacking. We compared the resting energy expenditure per fat-free mass (REE/FFM) in TS with other girls with short stature treated with growth hormone (GH) and age-related controls. We measured prospectively REE by spirometry under fasting conditions in the morning in 85 short prepubertal girls at the start of GH treatment. Diagnoses were TS (n=20), GH deficiency (GHD) (n=38) and small for gestational age (SGA) short stature (n=27). Additionally, 20 age-related controls were studied. Mean ages were 8.3 (TS), 7.1 (GHD), 6.9 (SGA) and 8.5 years (controls). Mean heights were -2.90 (TS), -3.32 (GHD), -3.69 (SGA) and -0.03 standard deviation scores (SDS) (controls). FFM was measured by bioelectrical impedance analysis (BIA). At the start of GH girls with TS showed insignificantly higher REE per FFM (REE/FFM) (mean±SD; 65±9 kcal/kg×day) than did the other female patients (62±9 kcal/kg×day) (p>0.23). The healthy controls had significantly lower REE/FFM (35±4 kcal/kg×day) (p<0.001). Follow-up examination of the patients after 6 or 12 months revealed decreasing REE/FFM in TS (62±9 kcal/kg×day) resulting in comparable REE/FFM in all three patient groups. At baseline short girls with TS had insignificantly higher REE/FFM than short children with SGA or GHD, but in follow-up this difference was not detectable any more. Future studies are necessary to understand this observation.

This study aimed to examine associations of three single-nucleotide polymorphisms (SNPs) with obesity-related phenotypes in Chinese children. These SNPs were identified by a recent genome-wide association (GWA) study among European children. Given that varied genetic backgrounds across different ethnicity may result in different association, it is necessary to study these associations in a different ethnic population. A total of 3,922 children, including 2,191 normal-weight, 873 overweight and 858 obese children, from three independent studies were included in the study. Logistic and linear regressions were performed, and meta-analyses were conducted to assess the associations between the SNPs and obesity-related phenotypes. The pooled odds ratios of the A-allele of rs564343 in PACS1 for obesity and severe obesity were 1.180 (p = 0.03) and 1.312 (p = 0.004), respectively. We also found that rs564343 was nominally associated with BMI, BMI standard deviation score (BMI-SDS), waist circumference, and waist-to-height ratio (p < 0.05). We showed for the first time that the rs564343 in PACS1 was associated with risk of severe obesity in a non-European population. This SNP was also found to be associated with common obesity and various obesity-related phenotypes in Chinese children, which had not been reported in the original study. The results demonstrated the value of conducting genetic researches in populations with different ethnicity. © 2017 The Author(s) Published by S. Karger GmbH, Freiburg.

2008-01-01

The equilibria and kinetics of the complex formation and dissociation reaction between gallium(III) and PAR [4-(2-pyridylazo)resorcinol] have been investigated in water and in the presence of SDS micelles. The reactive form of Ga(III) is GaOH2+ in both cases. The addition of SDS results in an increase of both the binding affinity and velocity, the maximum accelerating effect being observed just above the cmc value of SDS that, under the conditions of the experiments, is 5.6 x 10-3 M. At pH = 3.2, the maximum value of the equilibrium constant ratio Kapp(SDS)/Kapp(H2O) is 27.4, whereas that of the binding rate constants kf(SDS)/kf(H2O) is 16. The results are interpreted in terms of increased concentrations of the reactants on the micelle surface and on competition of PAR and SDS for GaOH2+.

Efficient renaturation of inclusion body proteins denatured by SDS.

Inclusion bodies are often formed when the foreign protein is over expressed in Escherichia coli. Since proteins in inclusion bodies are inactive, denaturing and refolding of inclusion body proteins are necessary to obtain the active form. Instead of the conventional denaturants, urea and guanidine hydrochloride, a strong anionic detergent SDS was used to solubilize C-terminal His-tag form of ulvan lyase in the inclusion bodies. Solution containing SDS-solubilized enzyme were kept on ice to precipitate SDS, followed by SDS-KCl insoluble crystal formation to remove SDS completely. After removing the precipitate by centrifugation, the supernatant was applied to Ni-NTA column to purify His-tagged ulvan lyase. The purified protein showed a dimeric form and ulvan lyase activity, demonstrating that SDS-denatured protein was renatured and recovered enzyme activity. This simple method could be useful for refolding other inclusion body proteins. Copyright © 2017 Elsevier Inc. All rights reserved.

Alkyl sulfates (AS), such as sodium dodecyl sulfate (SDS), are widely used in household and industrial products, and can be found in some wastewater and waste activated sludge (WAS). The effect of SDS on the fermentation of WAS at ambient temperature was investigated in this paper. Experimental results showed that the concentrations of protein and carbohydrate in aqueous phase increased with the amount of SDS. The concentrations of both NH(4)(+)-N and PO(4)(3-)-P in fermentation liquor also increased in the presence of SDS. In addition, it was observed that the fermentative short-chain fatty acids (SCFAs) concentration was affected by SDS. With the increase of SDS dosage, the maximum SCFAs concentration increased, and the fermentation time before reaching the maximum SCFAs concentration also increased. Further investigation showed that the produced SCFAs consisted of acetic, propionic, n-butyric, iso-butyric, n-valeric and iso-valeric acids, and acetic, iso-valeric and propionic acids were the three main products. The influence of SDS on methanogenesis was also investigated, and the inhibitory effect of SDS on methanogens activity was observed.

The Global Assessment of Functioning (GAF) Scale is used in routine clinical practice and research to estimate symptom and functional severity and longitudinal change. Concerns about poor interrater reliability have been raised, and the present study evaluated the effect of a Web-based GAF training program designed to improve interrater reliability in routine clinical practice. Clinicians rated up to 20 vignettes online, and received deviation scores as immediate feedback (i.e., own scores compared with expert raters) after each rating. Growth curves of absolute SD scores across the vignettes were modeled. A linear mixed effects model, using the clinician's deviation scores from expert raters as the dependent variable, indicated an improvement in reliability during training. Moderation by content of scale (symptoms; functioning), scale range (average; extreme), previous experience with GAF rating, profession, and postgraduate training were assessed. Training reduced deviation scores for inexperienced GAF raters, for individuals in clinical professions other than nursing and medicine, and for individuals with no postgraduate specialization. In addition, training was most beneficial for cases with average severity of symptoms compared with cases with extreme severity. The results support the use of Web-based training with feedback routines as a means to improve the reliability of GAF ratings performed by clinicians in mental health practice. These results especially pertain to clinicians in mental health practice who do not have a masters or doctoral degree. (c) 2015 APA, all rights reserved.

This study investigated whether intonation deficits were observed in 19 Cantonese-speaking adults with high-functioning autism (HFA) when compared to 19 matched neurotypical (NT) controls. This study also investigated the use of sentence-final particles (SFPs) and their relationship with intonation in both groups. Standard deviations (SDs) of the fundamental frequency (F0), the total number and the type of SFPs were calculated based on narrative samples. The HFA group demonstrated significantly higher SD of F0 and a positive correlation between the type of SFPs and SD of F0. Both groups produced a similar total number and type of SFPs. The results supported the universality of atypical intonation in ASD. The relationship between intonation and SFPs could be further explored by focusing on sentences containing SFPs.

Robust LOD scores for variance component-based linkage analysis.

PubMed

Blangero, J; Williams, J T; Almasy, L

2000-01-01

The variance component method is now widely used for linkage analysis of quantitative traits. Although this approach offers many advantages, the importance of the underlying assumption of multivariate normality of the trait distribution within pedigrees has not been studied extensively. Simulation studies have shown that traits with leptokurtic distributions yield linkage test statistics that exhibit excessive Type I error when analyzed naively. We derive analytical formulae relating the deviation from the expected asymptotic distribution of the lod score to the kurtosis and total heritability of the quantitative trait. A simple correction constant yields a robust lod score for any deviation from normality and for any pedigree structure, and effectively eliminates the problem of inflated Type I error due to misspecification of the underlying probability model in variance component-based linkage analysis.

Seasonal variation in size-dependent survival of juvenile Atlantic salmon (Salmo salar): Performance of multistate capture-mark-recapture models

2008-01-01

We estimated the magnitude and shape of size-dependent survival (SDS) across multiple sampling intervals for two cohorts of stream-dwelling Atlantic salmon (Salmo salar) juveniles using multistate capture-mark-recapture (CMR) models. Simulations designed to test the effectiveness of multistate models for detecting SDS in our system indicated that error in SDS estimates was low and that both time-invariant and time-varying SDS could be detected with sample sizes of >250, average survival of >0.6, and average probability of capture of >0.6, except for cases of very strong SDS. In the field (N ??? 750, survival 0.6-0.8 among sampling intervals, probability of capture 0.6-0.8 among sampling occasions), about one-third of the sampling intervals showed evidence of SDS, with poorer survival of larger fish during the age-2+ autumn and quadratic survival (opposite direction between cohorts) during age-1+ spring. The varying magnitude and shape of SDS among sampling intervals suggest a potential mechanism for the maintenance of the very wide observed size distributions. Estimating SDS using multistate CMR models appears complementary to established approaches, can provide estimates with low error, and can be used to detect intermittent SDS. ?? 2008 NRC Canada.

pH regulation of the kinetic stability of the lipase from Thermomyces lanuginosus.

2013-01-08

Thermomyces lanuginosus lipase (TlL) is a kinetically stable protein, resistant toward both denaturation and refolding in the presence of the ionic surfactant sodium dodecyl sulfate (SDS) and the nonionic surfactant decyl maltoside (DecM). We investigate the pH dependence of this kinetic stability. At pH 8, TlL remains folded and enzymatically active at multimillimolar surfactant concentrations but fails to refold from the acid urea-denatured state at submillimolar concentrations of SDS and DecM, indicating a broad concentration range of kinetic trapping or hysteresis. At pH 8, very few SDS molecules bind to TlL. The hysteresis SDS concentration range shrinks when moving to pH 4-6; in this pH range, SDS binds as micellelike clusters. Although hysteresis can be eliminated by reducing disulfide bonds, destabilizing the native state, and lowering the unfolding activation barrier, SDS sensitivity is not directly linked to intrinsic kinetic stability [its resistance to the general chemical denaturant guanidinium chloride (GdmCl)], because TlL unfolds more slowly in GdmCl at pH 6.0 than at pH 8.0. However, the estimated net charge drops from approximately -12 to approximately -5 between pH 8 and 6. SDS denatures TlL at pH 6.0 by nucleating via a critical number of bound SDS molecules on the surface of native TlL to form clusters. These results imply that SDS sensitivity is connected to the availability of appropriately charged regions on the protein. We suggest that conformational rigidity is a necessary but not sufficient feature of SDS resistance, because this has to be combined with sufficient negative electrostatic potential to avoid extensive SDS binding.

Tanshinone IIA (TSIIA) on solid dispersions (SDs) has thermodynamical instability of amorphous drug. Ternary solid dispersions (tSDs) can extend the stability of the amorphous form of drug. Poloxamer 188 was used as a SD carrier. Nano-CaCO3 played an important role in adsorption of biomolecules and is being developed for a host of biotechnological applications. The aim of the present study was to investigate the dissolution behavior and accelerated stability of TSIIA on solid dispersions (SDs) by the use of ternary systems with nano-CaCO3 and poloxamer 188. The TSIIA tSDs were prepared by a spray-drying method. First, the effect of combination of poloxamer 188 and nano-CaCO3 on TSIIA dissolution was studied. Subsequently, a set of complementary techniques (DSC, XRPD, SEM and FTIR) was used to monitor the physical changes of TSIIA in the SDs. Finally, stability test was carried out under the conditions 40°C/75% RH for 6 months. The characterization of tSDs by differential scanning calorimetry analysis (DSC) and X-ray powder diffraction (XRPD) showed that TSIIA was present in its amorphous form. Fourier transforms infrared spectroscopy (FTIR) suggested the presence of interactions between TSIIA and carriers in tSDs. Improvement in the dissolution rate was observed for all SDs. The stability study conducted on SDs with nano-CaCO3 showed stable drug content and dissolution behavior, over the period of 6 months as compared with freshly prepared SDs. SDs preparation with nano-CaCO3 and poloxamer 188 may be a promising approach to enhance the dissolution and stability of TSIIA.

The objective of the present study is to evaluate whether IL-6, TNF-α, IL-10 are associated with nutritional status in patients with cirrhosis secondary to biliary atresia and compare to healthy controls. The parameters used for nutritional assessment were the standard deviation scores of height-for-age and of triceps skinfold thickness-for-age. The severity of cirrhosis was evaluated using the Child-Pugh score and PELD/MELD. Serum cytokines were measured using Cytometric Bead Array flow cytometry. IL-6, TNF-α, and IL-10 were significantly higher in the cirrhosis group when compared with the control group (2.4 vs. 0.24 (p<0.001), 0.21 vs. 0.14 (p=0.007), and 0.65 vs. 0.36 (p=0.004), respectively. IL-6 and IL-10 were positively correlated with disease severity (0.450 [p=0.001] and 0.410; [p=0.002], respectively). TNF-α did not show a significant correlation with disease severity (0.100; p=0.478). Regarding nutritional evaluation, IL-6 was negatively correlated with the standard deviation score of height-for-age (-0.493; p<0.001) and of triceps skinfold thickness-for-age (-0.503; p<0.001), respectively. IL-10 exhibited a negative correlation with the standard deviation score of height-for-age (-0.476; p<0.001) and the standard deviation score of triceps skinfold thickness-for-age (-0.388; p=0.004). TNF-α did not show any significance in both anthropometric parameters (-0.083 (p=0.555) and -0.161 (p=0.253). The authors suggest that, in patients with cirrhosis secondary to biliary atresia, IL-6 could be used as a possible supporting biomarker of deficient nutritional status and elevated IL-10 levels could be used as a possible early-stage supporting biomarker of deteriorating nutritional status.

How does the past of a soccer match influence its future? Concepts and statistical analysis.

PubMed

Heuer, Andreas; Rubner, Oliver

2012-01-01

Scoring goals in a soccer match can be interpreted as a stochastic process. In the most simple description of a soccer match one assumes that scoring goals follows from independent rate processes of both teams. This would imply simple Poissonian and Markovian behavior. Deviations from this behavior would imply that the previous course of the match has an impact on the present match behavior. Here a general framework for the identification of deviations from this behavior is presented. For this endeavor it is essential to formulate an a priori estimate of the expected number of goals per team in a specific match. This can be done based on our previous work on the estimation of team strengths. Furthermore, the well-known general increase of the number of the goals in the course of a soccer match has to be removed by appropriate normalization. In general, three different types of deviations from a simple rate process can exist. First, the goal rate may depend on the exact time of the previous goals. Second, it may be influenced by the time passed since the previous goal and, third, it may reflect the present score. We show that the Poissonian scenario is fulfilled quite well for the German Bundesliga. However, a detailed analysis reveals significant deviations for the second and third aspect. Dramatic effects are observed if the away team leads by one or two goals in the final part of the match. This analysis allows one to identify generic features about soccer matches and to learn about the hidden complexities behind scoring goals. Among others the reason for the fact that the number of draws is larger than statistically expected can be identified.

To examine the associations of body fatness, metabolic and inflammatory markers with retinal vessel calibers among children. We performed a population-based cohort study among 4145 school-age children. At the median age of 6.0 years (95% range 5.8, 8.0 years), we measured body mass index, total and abdominal fat mass, metabolic and inflammatory markers (blood levels of lipids, insulin and C-peptide and C-reactive protein) and retinal vascular calibers from retinal photographs. We observed that compared with normal weight children, obese children had narrower retinal arteriolar caliber (difference -0.21 s.d. score (SDS; 95% confidence interval (CI) -0.35, -0.06)), but not venular caliber. Continuous analyses showed that higher body mass index and total body fat mass, but not android/gynoid fat mass ratio and pre-peritoneal fat mass, were associated with narrower retinal arteriolar caliber (P<0.05 for body mass index and total body fat mass), but not with retinal venular caliber. Lipid and insulin levels were not associated with retinal vessel calibers. Higher C-reactive protein was associated with only wider retinal venular caliber (difference 0.10 SDS (95% CI 0.06, 0.14) per SDS increase in C-reactive protein). This latter association was not influenced by body mass index. Higher body fatness is associated with narrower retinal arteriolar caliber, whereas increased C-reactive protein levels are associated with wider retinal venular caliber. Increased fat mass and inflammation correlate with microvascular development from school-age onwards.

Higher birth weight is associated with higher body mass index, traditionally interpreted as greater fatness or obesity, in later life. However, its relation with individual body-composition components and fat distribution remains unclear. We investigated associations between birth weight and later fat mass (FM), fat-free mass (FFM), and fat distribution. Body composition was assessed by the criterion 4-component model in 391 healthy children [mean (+/-SD) age, 11.7 +/- 4.2 y; 188 boys]. FM and FFM were adjusted for height (FMI = FM/height(2); FFMI = FFM/height(2)) and were expressed as SD scores (SDS). Findings were compared between the 4-component and simpler methods. Birth weight was positively associated with height in both sexes and was significantly positively associated with FFMI in boys, equivalent to a 0.18 SDS (95% CI: 0.04, 0.32) increase in FFMI per 1 SDS increase in birth weight. These associations were independent of puberty, physical activity, social class, ethnicity, and parental body mass index. Birth weight was not significantly related to percentage fat, FMI, or trunk FMI in either sex. Equivalent analyses using simpler methods showed a trend for a positive relation between birth weight and FMI in boys that became nonsignificant after adjusting for confounders. FFMI in later life in males is influenced by birth weight, a proxy for prenatal growth, but evidence for fetal programming of later FM or central adiposity is weak. Different body-composition techniques and data interpretation can influence results and should be considered when comparing studies.

Myocardial perfusion SPECT (MPS) is a noninvasive method commonly used for assessment of the hemodynamic significance of intermediate coronary stenoses. Fractional flow reserve (FFR) measurement is a well-validated invasive method used for the evaluation of intermediate stenoses. We aimed to determine the association between MPS and FFR findings in intermediate degree stenoses and evaluate the added value of quantification in MPS. Fifty-eight patients who underwent intracoronary pressure measurement in the catheterization laboratory to assess the physiological significance of intermediate (40-70%) left anterior descending (LAD) artery lesions, and who also underwent stress myocardial perfusion SPECT either for the assessment of an intermediate stenosis or for suspected coronary artery disease were analyzed retrospectively in the study. Quantitative analysis was performed using the 4DMSPECT program, with visual assessment performed by two experienced nuclear medicine physicians blinded to the angiographic findings. Summed stress scores (SSS) and summed difference scores (SDS) in the LAD artery territory according to the 20 segment model were calculated. A summed stress score of ≥ 3 and an SDS of ≥ 2 were assumed as pathologic, indicating significance of the lesion; a cutoff value of 0.75 was used to define abnormal FFR. Both visual and quantitative assessment results were compared with FFR using Chi-square (χ²) test. The mean time interval between two studies was 13 ± 11 days. FFR was normal in 45 and abnormal in 13 patients. Considering the FFR results as the gold standard method for assessing the significance of the lesion, the sensitivity and specificity of quantitative analysis determining the abnormal flow reserve were 85 and 84%, respectively, while visual analysis had a sensitivity of 77% and a specificity of 51%. There was a good agreement between the observers (κ = 0.856). Summed stress and difference scores demonstrated moderate inverse correlations with FFR values (r = -0.542, p < 0.001 and r = -0.506, p < 0.001, respectively). Quantitative analysis of the myocardial perfusion SPECT increases the specificity in evaluating the significance of intermediate degree coronary lesions.

Background In 2010 the Beijing Municipal Government promulgated a policy aimed at improving the quality of life and subjective well-being of elderly residents that included a component focused on mental health. Aim Identify factors associated with subjective well-being in a representative sample of elderly residents of Xi Cheng District in Beijing. Methods This cross-sectional study administered a self-completion survey to a stratified random sample of 2342 residents of Xi Cheng District who were 60 to 80 years of age. The level of well-being was assessed using a validated Chinese version of the Memorial University of Newfoundland Scale of Happiness (MUNSH). Detailed socioeconomic variables were obtained using a questionnaire developed by the authors. Social support, anxiety, and depression were assessed using validated Chinese versions of the Social Support Rating Scale (SSRS), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS). Results Among the 2342 respondents, 1616 (69.0%) had a total MUNSH score of 32 or above, indicating a high level of happiness; 423 (18.1%) has a total SSRS score 32 or below, indicating poor social support; 201 (8.6%) had a total SDS score of 53 or above, indicating significant depression; and 126 (5.3%) had a total SAS score of 50 or above, indicating significant anxiety. In the multivariate regression analysis the self-reported level of depression was the most important factor related to well-being. Anxiety, social support, income level, the quality of family relationships, the ability to self-regulate emotions, and regular exercise were also significantly related to well-being; but gender, marital status, age and educational level were not associated with well-being. Conclusion Among elderly urban residents in Beijing, self-reports of poor subjective well-being are closely associated with self-reports of depressive and anxiety symptoms and also associated with social factors such as social support, income level and family relationships. Prospective studies are needed to identify the causal relationships of these variables and, based on the findings, to develop targeted interventions aimed at improving the quality of life and well-being of elderly community members.
