The efficacy and safety of primary intraocular lens (IOL) implantation during early infancy is unknown. To compare the visual outcomes of patients optically corrected with contact lenses vs IOLs following unilateral cataract surgery during early infancy. The Infant Aphakia Treatment Study is a randomized clinical trial with 5 years of follow-up that involved 114 infants with unilateral congenital cataracts at 12 sites. A traveling examiner assessed visual acuity at age 4.5 years. Cataract surgery with or without primary IOL implantation. Contact lenses were used to correct aphakia in patients who did not receive IOLs. Treatment was determined through random assignment. HOTV optotype visual acuity at 4.5 years of age. The median logMAR visual acuity was not significantly different between the treated eyes in the 2 treatment groups (both, 0.90 [20/159]; P = .54). About 50% of treated eyes in both groups had visual acuity less than or equal to 20/200. Significantly more patients in the IOL group had at least 1 adverse event after cataract surgery (contact lens, 56%; IOL, 81%; P = .02). The most common adverse events in the IOL group were lens reproliferation into the visual axis, pupillary membranes, and corectopia. Glaucoma/glaucoma suspect occurred in 35% of treated eyes in the contact lens group vs 28% of eyes in the IOL group (P = .55). Since the initial cataract surgery, significantly more patients in the IOL group have had at least 1 additional intraocular surgery (contact lens, 21%; IOL, 72%; P < .001). There was no significant difference between the median visual acuity of operated eyes in children who underwent primary IOL implantation and those left aphakic. However, there were significantly more adverse events and additional intraoperative procedures in the IOL group. When operating on an infant younger than 7 months of age with a unilateral cataract, we recommend leaving the eye aphakic and focusing the eye with a contact lens. Primary IOL

The population of preterm infants is increasing and resources available for follow-up are limited. Early markers are needed to identify children who will show major as well as more subtle neurodevelopmental impairments. Such a challenge could be achieved with the Amiel-Tison Neurological Assessment at Term (ATNAT). This study assesses the usefulness of the ATNAT in the prediction of developmental problems at two years of corrected age (CA) in infants born between 29 and 37 weeks of gestation. Inclusion criteria were: gestational age between 29(0/7) and 36(6/7) weeks inclusively, birth weight below 2500g and minimal 24-hour stay in the Neonatal Intensive Care Unit of Sainte-Justine Hospital. A sample of 147 was prospectively recruited and assessed at two ages: at term with the ATNAT and at 24months CA with Bayley Scales of Infant Development-II. No major impairment such as cerebral palsy and no neurosensory impairment were observed. Developmental delay defined by an index<70 on the mental or psychomotor scale was reported respectively in 6.2% and 5.4% of the cohort. Significant differences in mental, psychomotor and behavioral performances were found according to neurological status. Neurological status was the only variable to enter the predictive model for psychomotor and behavioral indexes. Gender and neurological status remained in the predictive model for mental performance. This study supports the inclusion of the ATNAT among the eligibility criteria for systematic neurodevelopmental surveillance as it allows early identification of infants at higher risk of low developmental performances at 24months CA.

Lucas, Victoria S; McDonald, Fraser; Neil, Monica; Roberts, Graham

2014-08-01

The use of probability at the 18 year threshold has simplified the reporting of dental age estimates for emerging adults. The availability of simple to use widely available software has enabled the development of the probability threshold for individual teeth in growing children. Tooth development stage data from a previous study at the 10 year threshold were reused to estimate the probability of developing teeth being above or below the 10 year thresh-hold using the NORMDIST Function in Microsoft Excel. The probabilities within an individual subject are averaged to give a single probability that a subject is above or below 10 years old. To test the validity of this approach dental panoramic radiographs of 50 female and 50 male children within 2 years of the chronological age were assessed with the chronological age masked. Once the whole validation set of 100 radiographs had been assessed the masking was removed and the chronological age and dental age compared. The dental age was compared with chronological age to determine whether the dental age correctly or incorrectly identified a validation subject as above or below the 10 year threshold. The probability estimates correctly identified children as above or below on 94% of occasions. Only 2% of the validation group with a chronological age of less than 10 years were assigned to the over 10 year group. This study indicates the very high accuracy of assignment at the 10 year threshold. Further work at other legally important age thresholds is needed to explore the value of this approach to the technique of age estimation. Copyright © 2014. Published by Elsevier Ltd.

Altered brain volumes and associations between volumes and developmental outcomes have been reported in prematurely born children. To assess which regional brain volumes are different in very low birth weight (VLBW) children without neurodevelopmental impairments ([NDI] cerebral palsy, hearing loss, blindness and significantly delayed cognitive performance) compared with VLBW children with NDI, and to evaluate the association between regional brain volumes at term-equivalent age and cognitive development and neurological performance at a corrected age of 2 years. The study group consisted of a regional cohort of 164 VLBW children, divided into one group of children without NDI (n = 148) and one group of children with NDI (n = 16). Brain (MRI) was performed at term-equivalent age, from which brain volumes were manually analysed. Cognitive development was assessed with the Bayley Scales of Infant Development II (BSID-II), and neurological performance with the Hammersmith Infant Neurological Examination at the corrected age of 2 years. The volumes of total brain tissue, cerebrum, frontal lobes, basal ganglia and thalami, and cerebellum were significantly smaller, and the volume of the ventricles significantly larger, in the children with NDI than in those without NDI. Even in children without NDI, a smaller cerebellar volume was significantly correlated with poor neurological performance at 2 years of corrected age. Volumetric analysis at brain MRI can provide an additional parameter for early prediction of outcome in VLBW children.

To evaluate the role of extracurricular physical activity and sedentary behavior at preschool and primary school age on working memory at primary school age and adolescence, respectively. This prospective study was based on a birth cohort across 4 Spanish regions. In the 3 younger subcohorts (n = 1093), parents reported lifestyle habits of child at age 4 years of age on a questionnaire, and children performed a computerized working memory task at 7 years of age. In the older subcohort (n = 307), the questionnaire was completed at 6 years of age and working memory was tested at 14 years of age. Adjusted regression models were developed to investigate the associations between lifestyle habits and working memory. Low extracurricular physical activity levels at 4 years of age were associated with a nonsignificant 0.95% (95% CI -2.81 to 0.92) reduction of correct responses in the working memory task at age 7 years of age. Low extracurricular physical activity levels at 6 years of age were associated with a 4.22% (95% CI -8.05 to -0.39) reduction of correct responses at age 14 years. Television watching was not associated with working memory. Other sedentary behaviors at 6 year of age were associated with a 5.07% (95% CI -9.68 to -0.46) reduction of correct responses in boys at 14 years of age. Low extracurricular physical activity levels at preschool and primary school ages were associated with poorer working memory performance at primary school age and adolescence, respectively. High sedentary behavior levels at primary school age were related negatively to working memory in adolescent boys. Copyright © 2017 Elsevier Inc. All rights reserved.

Investigation of the age-related changes of the pineal gland function and possible ways for their overcoming on nonhuman monkey model was the purpose of this study. Hormonal function of the pineal gland was studied in 38 Macaca mulatta females of two age groups: 6-8 years old, n = 18 and 20-26 years old, n = 20. Pineal function was studied in basal conditions and after administration of pineal peptide preparations--epithalamin and epitalon, both developed in the St. Petersburg Institute of Bioregulation and Gerontology (Russia). It has been revealed that plasma melatonin concentration in monkeys has well expressed high amplitude diurnal rhythm. Minimum is manifested at 4 p.m. and maximum--at 10 p.m.-3 a.m. In aging the mean diurnal melatonin concentration decreases by 1.5-2 times as well as in different points of the day: 9 p.m., 10 p.m., 3 a.m. and 4 a.m. Administration of pineal peptides--epithalamin (at the dose 5 mg/animal/day intramuscularly during 10 consecutive days) or epitalon (at the dose 10 micrograms/animal/day intramuscularly during 7-10 consecutive days) induced significant increase in the night plasma melatonin in old monkeys, but the treatment did not change the melatonin level in young monkeys. Taking into consideration that melatonin is very important for regulation of the diurnal rhythm of functioning of some organs and systems it should be suggested that applying epithalamin and epitalon are perspective in the correction of age-related hormonal imbalance and age pathology.

To evaluate whether aggressive nutrition can improve long-term neurodevelopmental outcomes and growth in extremely low birth weight (ELBW) infants born appropriate for gestational age (AGA). This single-center cohort study included 137 ELBW AGA infants born in two epochs. The first group received standard nutrition (SN; n=79) consisting of amino acids started at 0.5g/kg/day on Day 4 of life and increased to 1.0g/kg/day. The second aggressive nutrition (AN) group received amino acids started at 1.5-2.0g/kg/day within 24h of life and increased to 3.5g/kg/day. Parenteral and enteral feedings were combined in both groups. Neurodevelopmental outcomes by the Kyoto Scale of Psychological Development and growth were followed up to 18months of corrected age or 3years of age and compared by univariate and multivariate analyses. Baseline characteristics were similar between the two groups. At 3years of age, AN children had a significantly greater mean value of head circumference, but not length or weight, than SN children (49.1 vs 48.0cm, p=0.014). The cognitive-adaptive (C-A) score in the AN group was also significantly higher than that in the SN group (98.3 vs 91.9 at 18months, p=0.039 and 89.5 vs 83.1 at 3years, p=0.047). AN infants born ≥26weeks of gestation were less likely to develop borderline disability in C-A, language-social and overall developmental scores compared to gestational age-matched SN infants. Parenteral and enteral AN after birth improved the long-term cognitive neurodevelopment in ELBW AGA infants, especially in those born ≥26weeks of gestational age, however results need to be confirmed in a larger, multi-site randomized trial.

Donor age has become the dominant donor factor used to predict graft failure (GF) after liver transplantation (LT) in hepatitis C virus (HCV) recipients. The purpose of this study was to develop and validate a model of corrected donor age (CDA) for HCV LT recipients that transforms the risk of other donor factors into the scale of donor age. We analyzed all first LT recipients with HCV in the United Network for Organ Sharing (UNOS) registry from January 1998 to December 2007 (development cohort, n = 14,538) and January 2008 to December 2011 (validation cohort, n = 7502) using Cox regression, excluding early GF (<90 days from LT). Accuracy in predicting 1 year GF (death or repeat LT) was assessed with the net reclassification index (NRI). In the development cohort, after controlling for pre-LT recipient factors and geotemporal trends (UNOS region, LT year), the following donor factors were independent predictors of GF, all P < 0.05: donor age (hazard ratio [HR], 1.02/year), donation after cardiac death (DCD; HR, 1.31), diabetes (HR, 1.23), height < 160 cm (HR, 1.13), aspartate aminotransferase (AST) ≥ 120 U/L (HR, 1.10), female (HR, 0.94), cold ischemia time (CIT; HR, 1.02/hour), and non-African American (non-AA) donor-African American (AA) recipient (HR, 1.65). Transforming these risk factors into the donor age scale yielded the following: DCD = +16 years; diabetes = +12 years; height < 160 cm = +7 years; AST ≥ 120 U/L = +5 years; female = -4 years; and CIT = +1 year/hour > 8 hours and -1 year/hour < 8 hours. There was a large effect of donor-recipient race combinations: +29 years for non-AA donor and an AA recipient but only +5 years for an AA donor and an AA recipient, and -2 years for an AA donor and a non-AA recipient. In a validation cohort, CDA better classified risk of 1-year GF versus actual age (NRI, 4.9%; P = 0.009) and versus the donor risk index (9.0%, P < 0.001). The CDA, compared

2009-02-01

The objective of this study was to compare the predictive value of qualitative MRI of brain structure at term and general movements assessments at 1 and 3 months' corrected age for motor outcome at 1 year's corrected age in very preterm infants. Eighty-six very preterm infants (<30 weeks' gestation) underwent MRI at term-equivalent age, were evaluated for white matter abnormality, and had general movements assessed at 1 and 3 months' corrected age. Motor outcome at 1 year's corrected age was evaluated with the Alberta Infant Motor Scale, the Neuro-Sensory Motor Development Assessment, and the diagnosis of cerebral palsy by the child's pediatrician. At 1 year of age, the Alberta Infant Motor Scale categorized 30 (35%) infants as suspicious/abnormal; the Neuro-Sensory Motor Development Assessment categorized 16 (18%) infants with mild-to-severe motor dysfunction, and 5 (6%) infants were classified with cerebral palsy. White matter abnormality at term and general movements at 1 and 3 months significantly correlated with Alberta Infant Motor Scale and Neuro-Sensory Motor Development Assessment scores at 1 year. White matter abnormality and general movements at 3 months were the only assessments that correlated with cerebral palsy. All assessments had 100% sensitivity in predicting cerebral palsy. White matter abnormality demonstrated the greatest accuracy in predicting combined motor outcomes, with excellent levels of specificity (>90%); however, the sensitivity was low. On the other hand, general movements assessments at 1 month had the highest sensitivity (>80%); however, the overall accuracy was relatively low. Neuroimaging (MRI) and functional (general movements) examinations have important complementary roles in predicting motor development of very preterm infants.

This study aimed to examine the association between child development at 5 years of age and mathematics ability and schooling outcomes at 12 years of age in Malawian children. A prospective cohort study looking at 609 rural Malawian children. Outcome measures were percentage of correctly answered mathematics questions, highest school grade completed and number of times repeating school grades at 12 years of age. A child development summary score obtained at 5 years of age was the main exposure variable. Regression analyses were used to estimate the association and adjust for confounders. Sensitivity analysis was performed by handling losses to follow-up with multiple imputation (MI) method. The summary score was positively associated with percentage of correctly answered mathematics questions (p = 0.057; p = 0.031 MI) and with highest school grade completed (p = 0.096; p = 0.070 MI), and negatively associated with number of times repeating school grades (p = 0.834; p = 0.339 MI). Fine motor score at 5 years was independently associated with the mathematic score (p = 0.032; p = 0.011 MI). The association between child development and mathematics ability did not depend on school attendance. Child development at 5 years of age showed signs of positive association with mathematics ability and possibly with highest school grade completed at 12 years of age. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.

Background Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. Objective To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. Design A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. Setting and Participants A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Main Outcome Measures Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Results Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Conclusions Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits. PMID:12796242

There is paucity of studies examining suicide rates in narrow five-year age-bands after the age of 60 years. This study examined suicide rates in eight five-year age-bands between the age of 60 and 99 years because this will allow more precise comparison between the young old (60-79 years) and the oldest old (80+ years) age groups. Data on the number of suicides (International Classification of Diseases - ICD-10 codes, X60-84) in each of the eight five-year age-bands between the age-bands 60-64 years and 95-99 years in both gender for as many years as possible from 2000 were ascertained from three sources: colleagues with access to national data, national statisics office websites and email contact with the national statistics offices. The population size for the corresponding years and age-bands was estimated for each country using data provided by the United Nations website. In men, suicide rates continued to increase for each of the seven five-year age-bands from 60-64 years to 90-94 years age-band, and then declined slightly for the 95-99 year age-band. In women, suicide rates continued to increase for each of the six five-year age-bands from 60-64 years to 85-89 years age-bands, and then declined slightly for the 90-94 years and 95-99 years age-bands. The overall global suicide rates for each of the eight five-year age-bands are sufficiently large for them to constitute a public health concern. This is especially important given the ongoing rise in the elderly population size and the paucity of data on risk and protective factors for suicide in the five-year age-bands after the age of 60 years.

A cross-sectional group study of the effects of aging on brain metabolism as measured with (18)F-FDG-PET was performed using several different partial volume correction (PVC) methods: no correction (NoPVC), Meltzer (MZ), Müller-Gärtner (MG), and the symmetric geometric transfer matrix (SGTM) using 99 subjects aged 65-87years from the Harvard Aging Brain study. Sensitivity to parameter selection was tested for MZ and MG. The various methods and parameter settings resulted in an extremely wide range of conclusions as to the effects of age on metabolism, from almost no changes to virtually all of cortical regions showing a decrease with age. Simulations showed that NoPVC had significant bias that made the age effect on metabolism appear to be much larger and more significant than it is. MZ was found to be the same as NoPVC for liberal brain masks; for conservative brain masks, MZ showed few areas correlated with age. MG and SGTM were found to be similar; however, MG was sensitive to a thresholding parameter that can result in data loss. CSF uptake was surprisingly high at about 15% of that in gray matter. The exclusion of CSF from SGTM and MG models, which is almost universally done, caused a substantial loss in the power to detect age-related changes. This diversity of results reflects the literature on the metabolism of aging and suggests that extreme care should be taken when applying PVC or interpreting results that have been corrected for partial volume effects. Using the SGTM, significant age-related changes of about 7% per decade were found in frontal and cingulate cortices as well as primary visual and insular cortices. Copyright © 2016 Elsevier Inc.

Marine radiocarbon reservoir age simulations for the past 50,000 years

Butzin, M.; Köhler, P.; Lohmann, G.

2017-08-01

Radiocarbon (14C) dating calibration for the last glacial period largely relies on cross-dated marine 14C records. However, marine reservoirs are isotopically depleted with respect to the atmosphere and therefore have to be corrected by the Marine Radiocarbon Ages of surface waters (MRAs), whose temporal variabilities are largely unknown. Here we present simulations of the spatial and temporal variability in MRAs using a three-dimensional ocean circulation model covering the past 50,000 years. Our simulations are compared to reconstructions of past surface ocean Δ14C. Running the model with different climatic boundary conditions, we find that low-latitude to midlatitude MRAs have varied between 400 and 1200 14C years, with values of about 780 14C years at the Last Glacial Maximum. Reservoir ages exceeding 2000 14C years are simulated in the polar oceans. Our simulation results can be used as first-order approximation of the MRA variability in future radiocarbon calibration efforts.

We assessed changes in age-specific prevalence of refractive error at the time of starting school, by comparing preschool and school age cohorts in Shanghai, China. A cross-sectional study was done in Jiading District, Shanghai during November and December 2013. We randomly selected 7 kindergartens and 7 primary schools, with probability proportionate to size. Chinese children (n = 8398) aged 3 to 10 years were enumerated, and 8267 (98.4%) were included. Children underwent distance visual acuity assessment and refraction measurement by cycloplegic autorefraction and subjective refraction. The prevalence of uncorrected visual acuity (UCVA), presenting visual acuity, and best-corrected visual acuity in the better eye of ≤20/40 was 19.8%, 15.5%, and 1.7%, respectively. Among those with UCVA ≤ 20/40, 93.2% could achieve visual acuity of ≥20/32 with refraction. Only 28.7% (n = 465) of children with UCVA in the better eye of ≤20/40 wore glasses. Prevalence of myopia (spherical equivalent ≤-0.5 diopters [D] in at least one eye) increased from 1.78% in 3-year-olds to 52.2% in 10-year-olds, while prevalence of hyperopia (spherical equivalent ≥+2.0 D) decreased from 17.8% among 3-year-olds to 2.6% by 10 years of age. After adjusting for age, attending elite "high-level" school was statistically associated with greater myopia prevalence. The prevalence of myopia was lower or comparable to that reported in other populations from age 3 to 5 years, but increased dramatically after 6 years, consistent with a strong environmental role of schooling on myopia development.

In compliance with inclusion and exclusion criteria, totally 40 children of school age (7-16 years old, ASA status I-II) with surgical pathology: (varicocele, cryptorchidism, inguinal hernia) were included A comperative assessment of neuropsychic status during pre - and postoperative are period in children, operated under propofol-fentanyl total intravenous anesthesia (TIVA) was conducted All patients were randomized to the control (without cepebroprotection 1st group, 20 children) and experimental (using cepebroprotection with hopaten acid within 1 month after the operation, 2nd group, 20 children) groups. Dimension of the study: Harvard standard monitoring, respiratory gas composition, neuropsychic tests (Bourdon test, "10 words test", etc.). For full compatibility groups (age, ASA status and anthropometric data, equal operation duration and the equipotential drug dosage adjustment is revealed, that in group of propofol-fentanyl TIVA in the early postoperative period in school age children postoperative cognitive dysfunction (POCD) is developing, which in case of absence of the corresponding correction is maintained after 1 month after operation (at least) in 80% of cases. In the application of hopaten acid cerebroprotection (40 mg/kg per day) severity of POCD reliably is reduced or compensated by the time of discharge from the hospital (3-7-th day when non-traumatic interventions), and 1 month after the operation in 30% of patients experienced improvement of cognitive functions, which proves the effectiveness of hopaten acid for POCD treatment. In case of propofol-fentanyl TIVA anesthesia in children of school age is indicated preventive prescription of multimodal cerebroprotectors without age limitations (for example hopaten acid (40 mg/kg per day) for POCD treatment.

We investigated the effects of ageing on balance corrections induced by sudden stance perturbations in different directions. Effects were examined in biomechanical and electromyographic (EMG) recordings from a total of 36 healthy subjects divided equally into three age groups (20–34, 35–55 and 60–75 years old). Perturbations consisted of six combinations of support-surface roll (laterally) and pitch (forward-backward) each with 7.5 deg amplitude (2 pure pitch, and 4 roll and pitch) delivered randomly. To reduce stimulus predictability further and to investigate scaling effects, perturbations were at either 30 or 60 deg s−1. In the legs, trunk and arms we observed age-related changes in balance corrections. The changes that appeared in the lower leg responses included smaller stretch reflexes in soleus and larger reflexes in tibialis anterior of the elderly compared with the young. For all perturbation directions, onsets of balance correcting responses in these ankle muscles were delayed by 20–30 ms and initially had smaller amplitudes (between 120–220 ms) in the elderly. This reduced early activity was compensated by increased lower leg activity after 240 ms. These EMG changes were paralleled by comparable differences in ankle torque responses, which were initially (after 160 ms) smaller in the elderly, but subsequently greater (after 280 ms). Findings in the middle-aged group were generally intermediate between the young and the elderly groups. Comparable results were obtained for the two different stimulus velocities. Stimulus-induced trunk roll, but not trunk pitch, changed dramatically with increasing age. Young subjects responded with early large roll movements of the trunk in the opposite direction to platform roll. A similarly directed but reduced amplitude of trunk roll was observed in the middle-aged. The elderly had very little initial roll modulation and also had smaller stretch reflexes in paraspinals.

The development of organic brain syndrome (OBS) was studied in a small group of survivors from a longitudinal investigation of aging twins. At the time of initial evaluation, the frequency of moderate to severe OBS was 25%. Among the 22 survivors who had a second psychiatric evaluation after approximately six years, the corrected rate for the development of OBS among those without it at the initial examination was 16%. Thus, the vast majority of those diagnosed as being without OBS at about the age of 80 years remained asymptomatic in subsequent years, supporting the view that OBS is not a necessary concomitant of old age, but the result of disease for which prevention and cure should be sought. Persons originally diagnosed as having OBS had the higher mortality, an observation in accord with prior reports in the literature. In the present study, the increased mortality was related to the severity of OBS but apparently independent of coexisting physical illness, again supporting the argument that OBS represents pathological as distinct from physiological aging.

2014-03-01

The American Academy of Pediatrics recommends that test scores should be corrected for prematurity up to 3 years of age, but this practice varies greatly in both clinical and research settings. The aim of this study was to contrast the effects of using chronological age and those of using corrected age on measures of cognitive outcome across childhood. A theoretical model was constructed using norms from the Bayley Scales of Infant and Toddler Development, Third Edition; the Wechsler Preschool and Primary Scale of Intelligence, Third Edition Australian; and the Wechsler Intelligence Scales for Children, Fourth Edition Australian. Baseline scores representing different levels of functioning (70, below average; 85, borderline; and 100, average) were recalculated using the normative data for ages 6 months to 16 years to account for 1, 2, 3 and 4 months of prematurity. The model created depicted the difference in standardised scores between chronological and corrected age. Compared with scores corrected for prematurity, the absolute reduction in scores using chronological age was greater for increasing degree of prematurity, younger ages at assessment and higher baseline scores and was substantial even beyond 3 years of age. However, the pattern was erratic, with considerable fluctuation evident across different ages and baseline scores. Chronological age results in a lowering of scores at all ages for preterm-born subjects that is greater in the first few years and in those born at earlier gestational ages. Whether or not to correct for prematurity depends upon the context of the assessment. © 2014 The Authors.

Objective Poor nutrition is thought to predispose to externalizing behavior problems, but to date there appear to have been no prospective longitudinal studies testing this hypothesis. This study assessed whether 1) poor nutrition at age 3 years predisposes to antisocial behavior at ages 8, 11, and 17 years, 2) such relationships are independent of psychosocial adversity, and 3) IQ mediates the relationship between nutrition and externalizing behavior problems. Method The participants were drawn from a birth cohort (N=1,795) in whom signs of malnutrition were assessed at age 3 years, cognitive measures were assessed at ages 3 and 11 years, and antisocial, aggressive, and hyperactive behavior was assessed at ages 8, 11, and 17 years. Results In relation to comparison subjects (N=1,206), the children with malnutrition signs at age 3 years (N=353) were more aggressive or hyperactive at age 8 years, had more externalizing problems at age 11, and had greater conduct disorder and excessive motor activity at age 17. The results were independent of psychosocial adversity and were not moderated by gender. There was a dose-response relationship between degree of malnutrition and degree of externalizing behavior at ages 8 and 17. Low IQ mediated the link between malnutrition and externalizing behavior at ages 8 and 11. Conclusions These results indicate that malnutrition predisposes to neurocognitive deficits, which in turn predispose to persistent externalizing behavior problems throughout childhood and adolescence. The findings suggest that reducing early malnutrition may help reduce later antisocial and aggressive behavior. PMID:15514400

Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits.

Complications Related to Pectus Carinatum Correction: Lessons Learned from 15 Years' Experience. Management and Literature Review.

Various methods of corrective thoracoplasty for pectus carinatum deformity have been described, but to date no studies describe a review of complications and how to manage them. Complications are dependent not only on the technique used and the patient's age, but also on the experience of the treating surgeon. The authors present their 15 years' experience with surgical correction of pectus carinatum and the complications that have occurred. A literature review regarding complications with pectus carinatum surgery is performed. A retrospective review of 95 patients (mean age, 19 years) was performed. One hundred four surgical procedures for repair of pectus carinatum were performed from July of 2000 to July of 2015 using a modified Ravitch technique, bioabsorbable material, postoperative bracing, and in some cases a diced rib cartilage graft technique. Intraoperative and postoperative complications were evaluated. The mean patient follow-up was 13.6 months (range, 4 months to 9.75 years). Intraoperative complications were pleura lesion and laceration of the internal mammary vein. Postoperative complications were recurrent mild protrusion, persistent protrusion of one or two costal cartilages, minor wound healing delay, skin ulcer, hypertrophic scar, transient intercostal dysesthesia, marginal pneumothorax, seroma, meningitis, and epidural hematoma. In our reported series of pectus carinatum repair, increasing experience and progressively less extensive techniques have resulted in fewer complications, low morbidity, and early return to activity. Complications were observed in the early period of application, predominantly because of a lack of experience, and usually subsided with increasing numbers of patients and frequency of surgery.

Significance of the cosmogenic argon correction in deciphering the 40Ar/39Ar ages of the Nakhlite (Martian) meteorites

All meteorites contain variable amounts of cosmogenic 38Ar and 36Ar produced during extraterrestrial exposure, and in order to calculate reliable 40Ar/39Ar ages this cosmogenic Ar must be removed from the total Ar budget. The amount of cosmogenic Ar has usually been calculated from the step-wise 38Ar/36Ar, minimum 36Ar/37Ar, or average 38Arcosmogenic/37Ar from the irradiated meteorite fragment. However, if Cl is present in the meteorite, then these values will be disturbed by Ar produced during laboratory neutron irradiation of Cl. Chlorine is likely to be a particular issue for the Nakhlite group of Martian meteorites, which can contain over 1000 ppm Cl [1]. An alternative method for the cosmogenic Ar correction uses the meteorite's exposure age as calculated from an un-irradiated fragment and step-wise production rates based on the measured Ca/K [2]. This calculation is independent of the Cl concentration. We applied this correction method to seven Nakhlites, analyzed in duplicate or triplicate. Selected samples were analyzed at both Lawrence Livermore National Laboratory and SUERC to ensure inter-laboratory reproducibility. We find that the cosmogenic argon correction of [2] has a significant influence on the ages calculated for individual steps, particularly for those at lower temperatures (i.e., differences of several tens of million years for some steps). The lower-temperature steps are more influenced by the alternate cosmogenic correction method of [2], as these analyses yielded higher concentrations of Cl-derived 38Ar. As a result, the Nakhlite data corrected using [2] yields step-heating spectra that are flat or nearly so across >70% of the release spectra (in contrast to downward-stepping spectra often reported for Nakhlite samples), allowing for the calculation of precise emplacement ages for these meteorites.

To determine whether the ability to predict severe motor impairment at age 5 years improves between birth and 18 months. Ancillary study of the Caffeine for Apnea of Prematurity Trial. International cohort of very low birth weight children who were assessed sequentially from birth to 5 years. Severe motor impairment was defined as a score <5th percentile on the Movement Assessment Battery of Children (MABC), or inability to complete the MABC because of cerebral palsy. Multivariable logistic regression cumulative risk models used four sets of predictor variables: early neonatal risk factors, risk factors at 36 weeks' postmenstrual age, risk factors at a corrected age of 18 months, and sociodemographic variables. A receiver operating characteristic curve (ROC) was generated for each model, and the four ROC curves were compared to determine if the addition of the new set of predictors significantly increased the area under the curve (AUC). Of 1469 children, 291 (19.8%) had a severe motor impairment at 5 years. The AUC increased from 0.650 soon after birth, to 0.718 (p<0.001) at 36 weeks' postmenstrual age, and to 0.797 at 18 months (p<0.001). Sociodemographic variables did not significantly improve the AUC (AUC=0.806; p=0.07). Prediction of severe motor impairment at 5 years of age using a cumulative risk model improves significantly from birth to 18 months of age in children with birth weights between 500 g and 1250 g.

Background Early childhood malnutrition is associated with cognitive and behavioral impairment during childhood and adolescence, but studies in adulthood are limited. Methods Using the NEO-PI-R personality inventory, we compared personality profiles at 37–43 years of age (mean 40.3 years, SD 1.9) of Barbadian adults who had experienced moderate to severe protein-energy malnutrition (PEM) in the first year of life (n=77) with healthy controls, who were former classmates of the index cases and were matched for age, sex and handedness in childhood (n=57). The previously malnourished participants had been rehabilitated, with good health and nutrition documented to 12 years of age, and study participants were followed longitudinally from childhood to 40 y. Group comparisons were adjusted for childhood and adolescent standard of living, with and without correcting for IQ. Results At the broad domain or factor level, previously malnourished participants had higher scores on Neuroticism and lower scores on Extraversion, Openness, Agreeableness and Conscientiousness than did the healthy controls At the sub-domain or facet level, previously malnourished participants reported more anxiety, vulnerability, shyness and lowered sociability, less intellectual curiosity, greater suspiciousness of others, a more egocentric than altruistic orientation, and a lowered sense of efficacy or competence. Conclusions Malnutrition limited to the first year of life with good health and nutrition documented to 12 years of age, is associated with a significant overrepresentation of adult personality trait scores outside of the average range. This outcome has important implications for a variety of important life and mental health outcomes. PMID:23488644

Situs inversus with levocardia and congenitally corrected transposition of the great arteries represents a relatively very rare congenital condition and most patients are diagnosed in infancy or early age. This case report describes a 35-year old man with congenitally corrected transposition of the great arteries which presented with a five month history of exertional dyspnea. A diagnosis was confirmed by transesophageal echocardiogram, showing situs inversus, levocardia, atrioventricular and ventriculoarterial discordance. He underwent physiologic repair, and was discharged thirty five days after the operation, in a good general condition. Although management of the corrected transposition of the great arteries patients remains controversial, the recommendation is that physiologic repair may be the procedure of choice for some patients, particularly complicated cases.

The objective of this study was to determine which ageing treatment of beef was sensorially preferred by consumers and how their preference changed when given information about the ageing treatment used. Longissimus thoracis et lumborum from four young bulls were randomly assigned three ageing treatments: dry ageing, vacuum ageing and ageing in a highly moisture permeable bag (bag dry-ageing); each was aged at 1.6 °C for another 13 days. A preference test (171 consumers) with questions about overall liking, tenderness, and juiciness was performed. Thereafter, a deceptive test (61 consumers) was performed with two taste samples, the first taste sample with correct information about ageing treatment and the second with false information. In the preference test, consumers preferred dry ageing and bag dry-ageing to vacuum ageing. In the deceptive test, dry ageing was preferred, but the information given influenced preference. © 2013.

Since 2010, the Advisory Committee on Immunization Practices (ACIP) has recommended that all persons aged ≥6months receive annual influenza vaccination. We analyzed data from the 2015 National Internet Flu Survey (NIFS), to assess knowledge and awareness of the influenza vaccination recommendation and early influenza vaccination coverage during the 2015-16 season among adults. Predictive marginals from a multivariable logistic regression model were used to identify factors independently associated with adults' knowledge and awareness of the vaccination recommendation and early vaccine uptake during the 2015-16 influenza season. Among the 3301 respondents aged ≥18years, 19.6% indicated knowing that influenza vaccination is recommended for all persons aged ≥6months. Of respondents, 62.3% indicated awareness that there was a recommendation for influenza vaccination, but did not indicate correct knowledge of the recommended age group. Overall, 39.9% of adults aged ≥18years reported having an influenza vaccination. Age 65years and older, being female, having a college or higher education, not being in work force, having annual household income ≥$75,000, reporting having received an influenza vaccination early in the 2015-16 season, having children aged ≤17years in the household, and having high-risk conditions were independently associated with a higher correct knowledge of the influenza vaccination recommendation. Approximately 1 in 5 had correct knowledge of the recommendation that all persons aged ≥6months should receive an influenza vaccination annually, with some socio-economic groups being even less aware. Clinic based education in combination with strategies known to increase uptake of recommended vaccines, such as patient reminder/recall systems and other healthcare system-based interventions are needed to improve vaccination, which could also improve awareness.

A new approach to cosmogenic corrections in 40Ar/ 39Ar chronometry: Implications for the ages of Martian meteorites

DOE PAGES

Cassata, W. S.; Borg, L. E.

2016-05-04

Anomalously old 40Ar/ 39Ar ages are commonly obtained from Shergottites and are generally attributed to uncertainties regarding the isotopic composition of the trapped component and/or the presence of excess 40Ar. Old ages can also be obtained if inaccurate corrections for cosmogenic 36Ar are applied. Current methods for making the cosmogenic correction require simplifying assumptions regarding the spatial homogeneity of target elements for cosmogenic production and the distribution of cosmogenic nuclides relative to trapped and reactor-derived Ar isotopes. To mitigate uncertainties arising from these assumptions, a new cosmogenic correction approach utilizing the exposure age determined on an un-irradiated aliquot and step-wisemore » production rate estimates that account for spatial variations in Ca and K is described. Data obtained from NWA 4468 and an unofficial pairing of NWA 2975, which yield anomalously old ages when corrected for cosmogenic 36Ar using conventional techniques, are used to illustrate the efficacy of this new approach. For these samples, anomalous age determinations are rectified solely by the improved cosmogenic correction technique described herein. Ages of 188 ± 17 and 184 ± 17 Ma are obtained for NWA 4468 and NWA 2975, respectively, both of which are indistinguishable from ages obtained by other radioisotopic systems. For other Shergottites that have multiple trapped components, have experienced diffusive loss of Ar, or contain excess Ar, more accurate cosmogenic corrections may aid in the interpretation of anomalous ages. In conclusion, the trapped 40Ar/ 36Ar ratios inferred from inverse isochron diagrams obtained from NWA 4468 and NWA 2975 are significantly lower than the Martian atmospheric value, and may represent upper mantle or crustal components.« less

To evaluate the efficacy and safety of an angle-supported foldable phakic intraocular lens (pIOL) for the correction of moderate to high myopia after 5 years follow-up. Prospective and retrospective, observational, longitudinal, non-randomised consecutive series of cases conducted on a total of 100 eyes of 67 patients with moderate to high myopia implanted with an Acrysof Cachet pIOL (Alcon Laboratories Inc.) with the aim of minimising the refractive error. The ages ranged between 18 to 60years. Uncorrected distance visual acuity (UDVA), manifest refraction, corrected distance visual acuity (CDVA), endothelial cells density, pIOL position, intraocular pressure, and complications were recorded preoperatively and during the 5 year follow-up. Five years after implantation, the mean manifest spherical equivalent refraction reduced significantly from -11.62±3.35 dioptres (D) to -0.33±0.85D. UDVA was 20/20 or better in 5 of 25 cases (20%), and 20/40 or better in 22 cases (88%). CDVA was 20/20 or better in 17 cases (68%), and 20/32 or better in 23 cases (92%) of eyes. The residual refractive error was within ±0.50D of emmetropia in 12 cases (48%), and within ±1.00D in 19 cases (76%). Mean endothelial cell loss at 5 years was 11.8% central, and 13.7% peripheral. Mean endothelium-pIOL distance was 2.11±0.18mm, and mean pIOL-crystalline distance was 0.88±0.20mm. This angle supported pIOL provided a favourable refractive correction and predictability, as well as acceptable safety in patients with moderate to high myopia. Although endothelial cell density decreased over 5years, the results are within the range reported in previous studies with other pIOLs. Copyright © 2016 Sociedad Española de Oftalmología.

To determine reference values for the HMC anomaloscope (Heidelberg multi-color anomaloscope) of healthy subjects. One hundred and thirteen healthy subjects were divided into four age groups: <20 years of age (ten female, five male), 20-39 years of age (23 female, 15 male), 40-59 years of age (23 female, ten male) and >60 years of age (nine female, 18 male). Match midpoint, matching range (MR) and anomaly quotient (AQ), according to the Moreland equation [blue (436 nm) + blue-green (490 nm) = cyan (480 nm) + yellow (589 nm)] and according to the Rayleigh equation [green (546 nm) + red (671 nm) = yellow (589 nm)] were determined. The neutral adaptation was done showing white light every 5 seconds in absolute mode and every 15 seconds in relative mode. The mean match midpoint according to the Rayleigh equation was 43.9 ± 2.6 scale units in absolute mode. It was highest between 20-39 years (45.2 ± 2.2) and lowest in subjects >60 years of age (42.2 ± 2.2). The mean MR in absolute mode was 3.1 ± 3.5 scale units with a maximum >60 years (4.4 ± 4.4). The MR in relative mode was between 1.6 ± 1.9 (20-39 years) and 4.4 ± 3.8 (>60 years). The resulting mean AQ was 1.01 ± 0.15 in both modes. The mean match midpoint of the Moreland equation was 51.0 ± 5.2 scale units in absolute mode. It was highest between 20-39 years (52.5 ± 5.7), and lowest in subjects >60 years of age (48.7 ± 3.6). The mean MR according to the Moreland equation was lower in absolute mode (13.4 ± 15.6) than in relative mode (16.2 ± 15.2). The mean resulting AQ was 1.02 ± 0.21 in both modes. The values of this study can be used as references for the diagnosis of red-green and blue perception impairment with the HMC anomaloscope.

There are limited data on the prognostic value of cardiovascular magnetic resonance measurements in idiopathic pulmonary arterial hypertension, with no studies investigating the impact of correction of cardiovascular magnetic resonance indices for age and sex on prognostic value. Consecutive patients with idiopathic pulmonary arterial hypertension underwent cardiovascular magnetic resonance imaging at 1.5T. Steady-state free precession cardiac volumes and mass measurements were corrected for age, sex, and body surface area according to reference data and prognostic significance assessed. A total of 80 patients with idiopathic pulmonary arterial hypertension were identified, and 23 patients died during the mean follow-up of 32±14 months. Corrected for age, sex, and body surface area, right ventricular end-systolic volume (P=0.004) strongly predicted mortality, independent of World Health Organization functional class, mean right atrial pressure, cardiac index, and mixed venous oxygen saturations. Consideration should be given to correcting cardiovascular magnetic resonance measures for age, sex, and body surface area, particularly given the changing demographics of patients with idiopathic pulmonary arterial hypertension. Corrected right ventricular end-systolic volume is a strong prognostic marker in idiopathic pulmonary arterial hypertension, independent of invasively derived measurements, mean right atrial pressure cardiac index, and mixed venous oxygen saturations.

To evaluate the feasibility and potential efficacy of an age-appropriate additional parenting intervention for very preterm born toddlers. In a randomized controlled pilot study, 60 of 94 eligible very preterm born children who had received a responsive parenting intervention in their first year were randomized to usual care or the additional intervention, consisting of 4-6 home visits between 18 and 22 months' corrected gestational age (CA). Parents were supported to responsively interact during increasingly complex daily activities and play. Parental satisfaction with the intervention was evaluated with a questionnaire. At baseline and 24 months CA, parents completed the Infant Toddler Social and Emotional Assessment, the Ages and Stages Questionnaire, and the Dutch Schlichting Lexilist for receptive language. At 24 months CA, motor, and cognitive development was measured by the Bayley Scales of Infant and Toddler Development, Third Edition Dutch version, and parent-child interaction was evaluated by the Emotional Availability Scales. Parental compliance and satisfaction with the intervention was high. Effect sizes (after correction for baseline variables) were small for internalizing and competence behavior, receptive language, and problem solving; medium for cognitive development and parent-child interaction; and large for externalizing and dysregulation behavior and motor development. After a postdischarge intervention during the first year, an additional responsive parenting support at toddler-age is feasible and associated with positive outcomes in a broad array of parental and child outcome measures. www.toetsingonline.nl: NL40208.018.12.

Due to increasingly numerous international migrations, estimating the age of unaccompanied minors is becoming of enormous significance for forensic professionals who are required to deliver expert opinions. The third molar tooth is one of the few anatomical sites available for estimating the age of individuals in late adolescence. This study verifies the accuracy of Cameriere's cut-off value of the third molar index (I3M) in assessing 18 years of age. For this purpose, a sample of orthopantomographs (OPTs) of 397 living subjects aged between 13 and 22 years (192 female and 205 male) was analyzed. Age distribution gradually decreases as I3M increases in both males and females. The results show that the sensitivity of the test was 86.6%, with a 95% confidence interval of (80.8%, 91.1%), and its specificity was 95.7%, with a 95% confidence interval of (92.1%, 98%). The proportion of correctly classified individuals was 91.4%. Estimated post-test probability, p was 95.6%, with a 95% confidence interval of (92%, 98%). Hence, the probability that a subject positive on the test (i.e., I3M<0.08) was 18 years of age or older was 95.6%. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

2017-01-01

Background Congenital talipes equinovarus (CTEV), also known as clubfoot, is common congenital orthopedic foot deformity in children characterized by four components of foot deformities: hindfoot equinus, hindfoot varus, midfoot cavus, and forefoot adduction. Although a number of conservative and surgical methods have been proposed to correct the clubfoot deformity, the relapses of the clubfoot are not uncommon. Several previous literatures discussed about the technical details of Ponseti method, adherence of Ponseti protocol among walking age or older children. However there is a necessity to investigate the relapse pattern, compliance of bracing, number of casts used in treatment and the percentages of surgical referral under two years of age for clear understanding and better practice to achieve successful outcome without or reduce relapse. Therefore this study aims to review the current evidence of Ponseti method (manipulation, casting, percutaneous Achilles tenotomy, and bracing) in the management of clubfoot under two years of age. Materials and methods Articles were searched from 2000 to 2015, in the following databases to identify the effectiveness of Ponseti method treatment for clubfoot: Medline, Cumulative Index to Nursing and Allied Health Literature (CINHAL), PubMed, and Scopus. The database searches were limited to articles published in English, and articles were focused on the effectiveness of Ponseti method on children with less than 2 years of age. Results Of the outcome of 1095 articles from four electronic databases, twelve articles were included in the review. Pirani scoring system, Dimeglio scoring system, measuring the range of motion and rate of relapses were used as outcome measures. Conclusions In conclusion, all reviewed, 12 articles reported that Ponseti method is a very effective method to correct the clubfoot deformities. However, we noticed that relapses occur in nine studies, which is due to the non-adherence of bracing regime and

50 Years of Cognitive Aging Theory.

Anderson, Nicole D; Craik, Fergus I M

2017-01-01

The objectives of this Introduction to the Journal of Gerontology: Psychological Sciences special issue on "50 Years of Cognitive Aging Theory" are to provide a brief overview of cognitive aging research prior to 1965 and to highlight significant developments in cognitive aging theory over the last 50 years. Historical and recent theories of cognitive aging were reviewed, with a particular focus on those not directly covered by the articles included in this special issue. Prior to 1965, cognitive aging research was predominantly descriptive, identifying what aspects of intellectual functioning are affected in older compared with younger adults. Since the mid-1960s, there has been an increasing interest in how and why specific components of cognitive domains are differentially affected in aging and a growing focus on cognitive aging neuroscience. Significant advances have taken place in our theoretical understanding of how and why certain components of cognitive functioning are or are not affected by aging. We also know much more now than we did 50 years ago about the underlying neural mechanisms of these changes. The next 50 years undoubtedly will bring new theories, as well as new tools (e.g., neuroimaging advances, neuromodulation, and technology), that will further our understanding of cognitive aging. © The Author 2016.

The Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, stakeholders, and researchers, developed the first Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years). These national guidelines are in response to a call from health and health care professionals, child care providers, and fitness practitioners for guidance on sedentary behaviour in the early years. The guideline development process followed the Appraisal of Guidelines for Research Evaluation (AGREE) II framework. The recommendations are informed by evidence from a systematic review that examined the relationships between sedentary behaviour (predominantly screen time) and health indicators (healthy body weight, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardio-metabolic disease risk factors) for three age groups (infants aged <1 year; toddlers aged 1-2 years; preschoolers aged 3-4 years). Evidence from the review was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The new guidelines include a preamble to provide context, followed by the specific recommendations. The final guidelines benefitted from extensive on-line consultations with input from >900 domestic and international stakeholders, end-users, and key informants. The final guidelines state: for healthy growth and development, caregivers should minimize the time infants (aged <1 year), toddlers (aged 1-2 years), and preschoolers (aged 3-4 years) spend being sedentary during waking hours. This includes prolonged sitting or being restrained (e.g., stroller, high chair) for more than 1 h at a time. For those under 2 years, screen time (e.g., TV, computer, electronic games) is not recommended. For children 2-4 years, screen time should be limited to under 1 h per day; less is better.

Sports-related concussion among professional, collegiate, and, more recently, high school athletes has received much attention from the media and medical community. To our knowledge, there is a paucity of research regarding parental knowledge of sports-related concussion. The aim of this study was to evaluate parental knowledge of concussion in young children who participated in recreational tackle football. Parents of children aged 5 years to 15 years attending recreational tackle football games were asked to complete an anonymous questionnaire based on the Centers for Disease Control and Prevention's Heads Up: Concussion in Youth Sports Quiz. The parents were asked about their level of agreement regarding statements that represent definition, symptoms, and treatment of concussion. A total of 310 of 369 parents (84% response rate) voluntarily completed the questionnaire, with 94% believing that their child had never had a concussion. However, only 13% (n = 41) could correctly identify all seven statements. Most did not identify that a concussion is considered a mild traumatic brain injury and can be achieved from something other than a direct blow to the head. Race, sex, and zip code had no significant association with correctly answering statements. Education (r = 0.24, p < 0.0001) and number of years the child played (r = 0.11, p = 0.049) had a small association. Fifty-three percent and 58% of the parents reported that someone had discussed the definition and the symptoms of concussion with them, respectively, with only about half reporting that information came from their health care provider. No parent was able to classify all symptoms listed as correctly related or not related to concussion. However, identification of correct concussion statements correlated with identification of correct symptoms (r = 0.25, p < 0.001). While most parents of young athletes demonstrated some knowledge regarding concussion, important misconceptions remain regarding the

Age and education corrected older adult normative data for a short form version of the Financial Capacity Instrument.

Financial capacity is an instrumental activity of daily living (IADL) that comprises multiple abilities and is critical to independence and autonomy in older adults. Because of its cognitive complexity, financial capacity is often the first IADL to show decline in prodromal and clinical Alzheimer's disease and related disorders. Despite its importance, few standardized assessment measures of financial capacity exist and there is little, if any, normative data available to evaluate financial skills in the elderly. The Financial Capacity Instrument-Short Form (FCI-SF) is a brief measure of financial skills designed to evaluate financial skills in older adults with cognitive impairment. In the current study, we present age- and education-adjusted normative data for FCI-SF variables in a sample of 1344 cognitively normal, community-dwelling older adults participating in the Mayo Clinic Study of Aging (MCSA) in Olmsted County, Minnesota. Individual FCI-SF raw scores were first converted to age-corrected scaled scores based on position within a cumulative frequency distribution and then grouped within 4 empirically supported and overlapping age ranges. These age-corrected scaled scores were then converted to age- and education-corrected scaled scores using the same methodology. This study has the potential to substantially enhance financial capacity evaluations of older adults through the introduction of age- and education-corrected normative data for the FCI-SF by allowing clinicians to: (a) compare an individual's performance to that of a sample of similar age and education peers, (b) interpret various aspects of financial capacity relative to a normative sample, and (c) make comparisons between these aspects.

Parenting influences child development, but it is unclear whether early parenting behavior can influence school-age outcomes in very preterm (VPT) children, and/or if certain groups of VPT children may be more affected by early parenting behavior. These research questions were examined. Participants were 147 children born <30 weeks' gestation or birth weight <1250 g and their primary caregiver. At term corrected age (CA), magnetic resonance imaging (MRI) was used to determine presence and severity of brain abnormality and medical data collected. High medical risk was defined as the presence of at least one of sepsis, necrotizing enterocolitis, bronchopulmonary dysplasia, moderate to severe white matter abnormality on MRI, or postnatal corticosteroids. At 2 years CA, parent-child interaction was assessed, and at 7 years CA, general intelligence (IQ), language, executive function, academic skills, and social-emotional functioning were assessed. Higher levels of parent-child synchrony, and parent facilitation, sensitivity and positive affect at 2 years were associated with better child outcomes at 7 years, while higher levels of intrusiveness and negative affect were associated with poorer outcomes. Many of these relationships remained after controlling for early child cognitive development. Interactions between child medical risk (higher/lower) and parenting were limited to child reading, math, and executive functioning outcomes, with stronger relationships for lower medical risk children. The contribution of early parenting to VPT children's school-age performance is significant, with stronger effects for lower medical risk children in some outcomes. These findings support the premise that parenting strategies should be included in the NICU and early interventions programs for VPT infants. © 2015 Association for Child and Adolescent Mental Health.

The best strategy for spectacle correction of presbyopia for near tasks has not been determined. Thirty volunteers over the age of 40 years were tested for subjective accommodative amplitude, pupillary size, fusional vergence, interpupillary distance, arm length, preferred working distance, near and far visual acuity and preferred reading correction in the phoropter and trial frames. Subjects performed near tasks (reading, writing and counting change) using various spectacle correction strengths. Predictors of the correction maximising near task comfort were determined by multivariable linear regression. The mean age was 54.9 years (range 43 to 71) and 40 per cent had diabetes. Significant predictors of the most comfortable addition in univariate analyses were age (p<0.001), interpupillary distance (p=0.02), fusional vergence amplitude (p=0.02), distance visual acuity in the worse eye (p=0.01), vision at 40 cm in the worse eye with distance correction (p=0.01), duration of diabetes (p=0.01), and the preferred correction to read at 40 cm with the phoropter (p=0.002) or trial frames (p<0.001). Target distance selected wearing trial frames (in dioptres), arm length, and accommodative amplitude were not significant predictors (p>0.15). The preferred addition wearing trial frames holding a reading target at a distance selected by the patient was the only independent predictor. Excluding this variable, distance visual acuity was predictive independent of age or near vision wearing distance correction. The distance selected for task performance was predicted by vision wearing distance correction at near and at distance. Multivariable linear regression can be used to generate tables based on distance visual acuity and age or near vision wearing distance correction to determine tentative near spectacle addition. Final spectacle correction for desktop tasks can be estimated by subjective refraction with trial frames.

Preterm infants are recognised as developing at a significantly slower rate than their full-term peers and with different movement quality. This study aimed to describe the longitudinal gross motor trajectories of these infants in the first 18 months of (corrected) age and investigate factors associated with gross motor development. A longitudinal study was conducted with convenience samples of 58 preterm infants born < or = 29 weeks of gestation and 52 control full-term infants in Australia. The infants were assessed at 4, 8, 12 and 18 months of (corrected) age using the Alberta Infant Motor Scale (AIMS). Forty-six preterm and 48 control infants completed all four assessments. The preterm group scored significantly lower on various sub-scores at all age levels. Almost half of the preterm infants demonstrated less progression in the sit sub-scale from 4 to 8 months (corrected) age, possibly due to an imbalance between flexor and extensor strength in the trunk. At 12 and 18 months of (corrected) age, lack of rotation and fluency in their movements were evident in some preterm infants. Presence of intra-ventricular haemorrhage and chronic lung disease were associated with poor motor performance at 4 months and use of postnatal steroids was associated with poor motor performance at 4, 8 and 18 months of corrected age. The imbalance between flexor and extensor muscle strength in preterm infants had a stronger impact on motor development than usually expected. The AIMS appears to be a sensitive assessment tool to demonstrate the unique movement characteristics in this preterm cohort. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Successful surgical correction of the complex anomaly of interruption of the aortic arch and intracardiac ventricular septal defect is reported. The patient was a boy 5 years old when he first came under treatment. The total correction was performed in two stages. At the first operation, at the age of 7 years, continuity of the aortic arch was achieved by insertion of a Teflon graft, employing left heart bypass. The ventricular septal defect was closed at the age of 13 years on total cardiopulmonary bypass. Two and half years after the total correction the boy is alive and well. The difficulties in diagnosing the condition are discussed. The role of left heart bypass is emphasized. Images PMID:5489187

Reports an error in "Perceived age discrimination across age in Europe: From an ageing society to a society for all ages" by Christopher Bratt, Dominic Abrams, Hannah J. Swift, Christin-Melanie Vauclair and Sibila Marques ( Developmental Psychology , 2018[Jan], Vol 54[1], 167-180). In the article, the copyright license has been changed to the Creative Commons CC-BY Attribution License. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2017-47508-001.) Ageism is recognized as a significant obstacle to older people's well-being, but age discrimination against younger people has attracted less attention. We investigate levels of perceived age discrimination across early to late adulthood, using data from the European Social Survey (ESS), collected in 29 countries (N = 56,272). We test for approximate measurement invariance across countries. We use local structural equation modeling as well as moderated nonlinear factor analysis to test for measurement invariance across age as a continuous variable. Using models that account for the moderate degree of noninvariance, we find that younger people report experiencing the highest levels of age discrimination. We also find that national context substantially affects levels of ageism experienced among older respondents. The evidence highlights that more research is needed to address ageism in youth and across the life span, not just old adulthood. It also highlights the need to consider factors that differently contribute to forms of ageism experienced by people at different life stages and ages.

New age- and sex-specific criteria for QT prolongation based on rate correction formulas that minimize bias at the upper normal limits.

2014-07-01

Existing formulas for rate-corrected QT (QTc) commonly fail to properly adjust the upper normal limits which are more critical than the mean QTc for evaluation of prolonged QT. Age- and sex-related differences in QTc are also often overlooked. Our goal was to establish criteria for prolonged QTc using formulas that minimize QTc bias at the upper normal limits. Strict criteria were used in selecting a study group of 57,595 persons aged 5 to 89 years (54% women) and to exclude electrocardiograms (ECG) with possible disease-associated changes. Two QT rate adjustment formulas were identified which both minimized rate-dependency in the 98 th percentile limits: QTcmod, based on an electrophysiological model (QTcMod = QTx(120 + HR)/180)), and QTcLogLin, a power function of the RR interval with exponents 0.37 for men and 0.38 for women. QTc shortened in men during adolescence and QTcMod became 13 ms shorter than in women at age 20-29 years. The sex difference was maintained through adulthood although decreasing with age. The criteria established for prolonged QTc were: Age < 40 years, men 430 ms, women 440 ms; Age 40 to 69, men 440 ms, women 450 ms; Age ≥ 70 years, men 455 ms, and women 460 ms. Sex difference in QTc originates from shortened QT in adolescent males. Upper normal limits for QTc vary substantially by age and sex, and it is essential to use age- and sex-specific criteria for evaluation of QT prolongation. Copyright © 2014 Elsevier Ireland Ltd.

2017-08-01

This study examines the selective, sustained, and executive attention abilities of very preterm (VPT) born children in relation to concurrent structural magnetic resonance imaging (MRI) measures of regional gray matter development at age 12 years. A regional cohort of 110 VPT (≤32 weeks gestation) and 113 full term (FT) born children were assessed at corrected age 12 years on the Test of Everyday Attention-Children. They also had a structural MRI scan that was subsequently analyzed using voxel-based morphometry to quantify regional between-group differences in cerebral gray matter development, which were then related to attention measures using multivariate methods. VPT children obtained similar selective (p=.85), but poorer sustained (p=.02) and executive attention (p=.01) scores than FT children. VPT children were also characterized by reduced gray matter in the bilateral parietal, temporal, prefrontal and posterior cingulate cortices, bilateral thalami, and left hippocampus; and increased gray matter in the occipital and anterior cingulate cortices (family-wise error-corrected p<.05). Poorer sustained auditory attention was associated with increased gray matter in the anterior cingulate cortex (p=.04). Poor executive shifting attention was associated with reduced gray matter in the right superior temporal cortex (p=.04) and bilateral thalami (p=.05). Poorer executive divided attention was associated with reduced gray matter in the occipital (p=.001), posterior cingulate (p=.02), and left temporal (p=.01) cortices; and increased gray matter in the anterior cingulate cortex (p=.001). Disturbances in regional gray matter development appear to contribute, at least in part, to the poorer attentional performance of VPT children at school age. (JINS, 2017, 23, 539-550).

Different Partial Volume Correction Methods Lead to Different Conclusions: an 18F-FDG PET Study of Aging

A cross-sectional group study of the effects of aging on brain metabolism as measured with 18F-FDG PET was performed using several different partial volume correction (PVC) methods: no correction (NoPVC), Meltzer (MZ), Müller-Gärtner (MG), and the symmetric geometric transfer matrix (SGTM) using 99 subjects aged 65-87 from the Harvard Aging Brain study. Sensitivity to parameter selection was tested for MZ and MG. The various methods and parameter settings resulted in an extremely wide range of conclusions as to the effects of age on metabolism, from almost no changes to virtually all of cortical regions showing a decrease with age. Simulations showed that NoPVC had significant bias that made the age effect on metabolism appear to be much larger and more significant than it is. MZ was found to be the same as NoPVC for liberal brain masks; for conservative brain masks, MZ showed few areas correlated with age. MG and SGTM were found to be similar; however, MG was sensitive to a thresholding parameter that can result in data loss. CSF uptake was surprisingly high at about 15% of that in gray matter. Exclusion of CSF from SGTM and MG models, which is almost universally done, caused a substantial loss in the power to detect age-related changes. This diversity of results reflects the literature on the metabolism of aging and suggests that extreme care should be taken when applying PVC or interpreting results that have been corrected for partial volume effects. Using the SGTM, significant age-related changes of about 7% per decade were found in frontal and cingulate cortices as well as primary visual and insular cortices. PMID:26915497

Ventricular septal defect (VSD) is the most common congenital heart defect, with larger VSDs typically being corrected with an open-heart surgery during infancy. Long-term consequences of a VSD-corrective surgery on stress systems of child and mother are still unknown. The aim of the present study is to investigate the associations of an early corrected VSD and diurnal cortisol release of child and mother. 26 children (12 boys) between 6 and 9 years old, who underwent surgery for an isolated VSD within the first 3 years of life, and their mothers participated in the study. Their diurnal cortisol profiles were compared to a sex-, age-, and socioeconomic status-matched healthy control group. Within the VSD group, associations between cortisol and characteristics of surgery and hospitalization were investigated. Child and mother psychopathological symptoms were considered as a possible interfering mechanism of altered cortisol profiles. Diurnal cortisol profiles of children with an early corrected VSD did not differ from those of controls. However, mothers of affected children exhibited higher cortisol levels in the morning ( p  < 0.001, [Formula: see text]) and a steeper diurnal cortisol slope ( p  = 0.016, [Formula: see text]) than mothers of healthy children. Results indicate a favorable development of children with an early corrected VSD, in terms of comparable diurnal cortisol profiles with healthy controls, according to a comparable mother-rated psychopathology. Mothers of affected children reveal altered diurnal cortisol levels, without differences in self-rated psychopathology. This divergence should be clarified in future research.

Personality Stability From Age 14 to Age 77 Years

PubMed Central

2016-01-01

There is evidence for differential stability in personality trait differences, even over decades. The authors used data from a sample of the Scottish Mental Survey, 1947 to study personality stability from childhood to older age. The 6-Day Sample (N = 1,208) were rated on six personality characteristics by their teachers at around age 14. In 2012, the authors traced as many of these participants as possible and invited them to take part in a follow-up study. Those who agreed (N = 174) completed a questionnaire booklet at age 77 years, which included rating themselves and asking someone who knew them well to rate them on the same 6 characteristics on which they were rated in adolescence. Each set of 6 ratings was reduced to the same single underlying factor, denoted dependability, a trait comparable to conscientiousness. Participants’ and others’ older-age personality characteristic ratings were moderately correlated with each other, and with other measures of personality and wellbeing, but correlations suggested no significant stability of any of the 6 characteristics or their underlying factor, dependability, over the 63-year interval. However, a more complex model, controlling rater effects, indicated significant 63-year stability of 1 personality characteristic, Stability of Moods, and near-significant stability of another, Conscientiousness. Results suggest that lifelong differential stability of personality is generally quite low, but that some aspects of personality in older age may relate to personality in childhood. PMID:27929341

This study describes trends in dietary diversity and food intake over 12 years according to age at first participation in the study. Prospective cohort study. The National Institute for Longevity Sciences - Longitudinal Study of Aging, a community-based study. Participants included 922 men and 879 women who participated in the first study-wave (age, 40-79 years) and also participated in at least one study-wave from the second to seventh study-wave. Study-waves were conducted biennially. Dietary intake was calculated from 3-day dietary records with photographs. Dietary diversity was determined using the Quantitative Index for Dietary Diversity based on food intake. A mixed-effects model was used to estimate linear changes in dietary diversity and food intake over 12 years according to age at first study-wave. Mean (standard deviation (SD)) follow-up time and number of study-wave visits were 9.5 (3.7) years and 5.4 (1.8), respectively. Mean (SD, range) dietary diversity score was 0.86 (0.06, 0.52-0.96) in men and 0.88 (0.04, 0.66-0.96) in women, respectively. Fixed effects for interactions of age and time with dietary diversity score were statistically significant (p<0.05). The slope of dietary diversity among men aged 40 to 55 years increased (40-year-old slope = 0.00093/year, p<0.01; 55-year-old slope = 0.00035/year, p=0.04), with a decreasing trend started at 65 years old, although this trend was not significant (65-year-old slope = -0.00003/year, p=0.88; 79-year-old slope = -0.00057/year, p=0.21). The slope of dietary diversity among women aged 40 to 44 years increased (40-year-old slope = 0.00053/year, p=0.02; 44-year-old slope = 0.00038/year, p=0.04), whereas the slope of dietary diversity among women aged 63 to 79 years decreased (63-year-old slope = -0.00033/year, p=0.03; 79-year-old slope = -0.00092/year, p<0.001). Fruit, milk and dairy intake decreased in men around their 60s; milk and dairy intake decreased in women around their 50s; and beans and fruit

To evaluate and correct the impact of non-response in the prevalence of underweight, overweight and obesity in children aged 6 to 15 years old using silhouette scales. Cross-sectional study carried out in 2013 among 8,145 Galician schoolchildren aged 6-15 years old. The students who agreed to participate were weighed and measured and, based on body mass index, the prevalence of underweight, overweight and obesity was estimated. Teachers rated all students using silhouette scales. The valuations were used to estimate the prevalence corrected by non-response. Using the Bayes theorem, participation rates were estimated according to weight status. The participation rate was 92.3% in the 6 -to 11-year-old group, and 90% in the 12- to 15-year old age group. In both groups, the prevalence of underweight and overweight were similar between participants and non-participants. However, obesity was higher among non-participants, especially at 12 to 15 years of age (6.3% vs. 12.2% ; p < 0.05). The prevalence did not change when corrected by the teacher's valuation. The participation rate of obese students was lower than the overall rate (82% vs. 90% at 12 to 15 years old; p < 0.05). The presence of participation bias, which was greater at 12-15 years old, was confirmed. However, the impact of the bias on prevalence was negligible due to the high participation rate. In obesity studies with objective measures, it is essential to quantify non-participation, as well as to assess its impact and correct it. Copyright © 2017 SESPAS.

Hyperopic undercorrection is a common clinical practice. However, less is known of its effect on the change in refractive errors and emmetropization throughout the later years of childhood. To evaluate the effect of spectacle correction on the change in refractive errors in hyperopic children less than 12 years of age with or without strabismus. A retrospective cohort study was performed by a computer based search of the hospital database of patients with hyperopia, accommodative esotropia or exotropia. A total of 150 hyperopic children under 12 years of age were included. Patients were classified into four groups: 1) accommodative esotropia with full correction of hyperopia, 2) exotropia with undercorrection of hyperopia, 3) orthotropia with full correction of hyperopia, 4) orthotropia with undercorrection of hyperopia. The 4 groups were matched by initial age on examination and spherical equivalent refractive errors (SER). The main outcome measure was the change in SER (Diopter/year) in both eyes after two years of follow-up. An overall negative shift in SER was noted during the follow-up period in all groups, except for the group with esotropia and full correction. The mean negative shift of hyperopia was more rapid in groups receiving undercorrection of hyperopia with or without strabismus. The amount of undercorrection of hyperopia was positively correlated to the magnitude of decrease in hyperopia in all patients (r = 0.289, P<0.001) and in the subgroup of patients with orthotropia (r = 0.304, P = 0.011). The amount of undercorrection of hyperopia was the only factor associated with a more negative shift in SER (OR, 2.414; 95% CI, 1.202-4.849; P = 0.013). The amount of undercorrection is significantly correlated to the change in hyperopic refractive errors. Full correction of hyperopia may inhibit emmetropization during early and late childhood.

Whether and how sex and age affect bariatric-surgery outcome is poorly understood. Estrogens regulate body composition in women and animals, and increase weight loss in a rodent model of gastric bypass, suggesting that premenopausal women may lose more weight following bariatric surgery. One thousand three hundred fifty-six female gastric-bypass or gastric-banding patients were retrospectively grouped as 20-45 years old (presumptively premenopausal; n = 1,199) and 55-65 years old (presumptively postmenopausal; n = 157). Mixed-model ANCOVA followed by Bonferroni-corrected t tests were used to categorically test the effect of age on percent excess body weight loss (%EBWL) at 1 and 2 years post-surgery, controlling for preoperative EBW and surgery type. Age effects were also tested dimensionally in all women and in 289 male patients. Twenty- to forty-five-year-old women showed greater %EBWL 1 and 2 years post-surgery than 55-65-year-old women (p's < 0.0005). No age effect was detected in 20-25- vs. 30-35-, 30-35- vs. 40-45-, or 20-25- vs. 40-45-year-old women (p's > 0.2) This age effect was detected only after gastric banding, with 20-45-year-old women losing ∼7 kg more than 55-65-year-old women after 2 years. Dimensional analysis confirmed a significant inverse effect of age on bariatric surgery outcome in women, but did not detect any effect in men. Results indicate that 55-65-year-old women lose less weight than 20-45-year-old women in the initial 2 years after bariatric surgery, especially gastric banding; this may be mediated by age- or menopause-associated changes in physical activity, energy expenditure, or energy intake.

The facial growth of Class III malocclusion worsens with age, in this case, the early orthopedic treatment, providing facial balance, modifying the maxillofacial growth and development. A 7.6-year old boy presented with Class III malocclusion associated with anterior crossbite; the mandible was shifted to the right and the maxilla had a transversal deficiency. Rapid maxillary expansion followed by facemask therapy was performed, to correct the anteroposterior relationship and improve the facial profile. The patient was followed for a 15-year period, after completion of the treatment, and stability was observed. Growing patients should be monitored following their treatment, so as to prevent malocclusion relapse. PMID:25760273

Reports an error in "Affect dynamics, affective forecasting, and aging" by Lisbeth Nielsen, Brian Knutson and Laura L. Carstensen (Emotion, 2008[Jun], Vol 8[3], 318-330). The first author of the article was listed as being affiliated with both the National Institute on Aging and the Department of Psychology, Stanford University. Dr. Nielsen would like to clarify that the research for this article was conducted while she was a postdoctoral fellow at Stanford University; her current affiliation is only with the National Institute on Aging. The copyright notice should also have been listed as "In the Public Domain." (The following abstract of the original article appeared in record 2008-06717-002.) [Correction Notice: The same erratum for this article was reported in Vol 8(5) of Emotion (see record 2008-13989-013).] Affective forecasting, experienced affect, and recalled affect were compared in younger and older adults during a task in which participants worked to win and avoid losing small monetary sums. Dynamic changes in affect were measured along valence and arousal dimensions, with probes during both anticipatory and consummatory task phases. Older and younger adults displayed distinct patterns of affect dynamics. Younger adults reported increased negative arousal during loss anticipation and positive arousal during gain anticipation. In contrast, older adults reported increased positive arousal during gain anticipation but showed no increase in negative arousal on trials involving loss anticipation. Additionally, younger adults reported large increases in valence after avoiding an anticipated loss, but older adults did not. Younger, but not older, adults exhibited forecasting errors on the arousal dimension, underestimating increases in arousal during anticipation of gains and losses and overestimating increases in arousal in response to gain outcomes. Overall, the findings are consistent with a growing literature suggesting that older people experience less

To examine the associations between Prechtl's General Movements Assessment (GMA), conducted from birth to term-equivalent age, and neurodevelopmental outcomes at 12 months corrected age, in infants born very preterm. One hundred and thirty-seven infants born before 30 weeks' gestation had serial GMA (categorized as 'normal' or 'abnormal') before term and at term-equivalent age. At 12 months corrected age, neurodevelopment was assessed using the Alberta Infant Motor Scale (AIMS); Neurological, Sensory, Motor, Developmental Assessment (NSMDA); and Touwen Infant Neurological Examination (TINE). The relationships between GMA at four time points and 12-month neurodevelopmental assessments were examined using regression models. Abnormal GMA at all time points were associated with worse continuous scores on the AIMS, NSMDA, and TINE (p<0.05). Abnormal GMA before term and at term-equivalent age were associated with increased odds of mild-severe dysfunction on the NSMDA (odds ratio [OR] 4.26, 95% confidence interval [CI] 1.55-11.71, p<0.01; and OR 4.16, 95% CI 1.55-11.17, p<0.01 respectively) and abnormal GMA before term with increased odds of suboptimal-abnormal motor function on the TINE (OR 2.75, 95% CI 1.10-6.85, p=0.03). Abnormal GMA before term and at term-equivalent age were associated with worse neurodevelopment at 12 months corrected age in children born very preterm. Abnormal general movements before term predict developmental deficits at 1 year in infants born very preterm. General Movements Assessment before term identifies at-risk infants born very preterm. © 2017 Mac Keith Press.

To investigate the role of television video games in childhood amblyopia treatment. This prospective, randomized, interventional study included 40 patients between 4-7 years of age, with unilateral amblyopia (visual acuity in amblyopic eye between 1-0.6 LogMAR equivalents) attending the squint clinic at a tertiary eye hospital. All patients were prescribed optimal spectacle correction and occlusion therapy, i.e. full time patching according to patient's age, was initiated after six weeks.; full-time patching according to patient's age was initiated after 6 weeks. Subjects were randomly divided into two groups of 20 each. Patients in the first group, Group A (control), were prescribed patching alone. Patients in the second group, Group B (study), were made to play action video games, with the help of a commercial television set, along with patching. They attended 12 half-hour sessions each, at weekly intervals. Follow-up assessments included best corrected visual acuity (BCVA) (both distance and near) and stereoacuity measurements at 3, 6, 9, and 12 weeks. The mean age of patients was 6.03 ± 1.14 years. The distance BCVA in the amblyopic eye showed a significant improvement at final follow-up (12 weeks) in both groups: from 0.84 ± 0.19 to 0.55 ± 0.21 LogMAReq in Group A and 0.89 ± 0.16 to 0.46 ± 0.22 LogMAReq in Group B. However, improvement in BCVA was significantly better in group B at all visits (P=0.002, 12 weeks). The study group also had a significantly better outcome in terms near visual acuity improvement (P = 0.006, 12 weeks). There was also greater stereoacuity improvement in group B, with 7 patients improving to 100 secs of arc or better. Video games supplemental to occlusion may be considered favorable for visual development in amblyopic children, and the study encourages further research on this subject.

(1) Background: Late preterm infants account for the majority of preterm births and are at risk of altered body composition. Because body composition modulates later health outcomes and human milk is recommended as the normal method for infant feeding, we sought to investigate whether human milk feeding in early life can modulate body composition development in late preterm infants; (2) Methods: Neonatal, anthropometric and feeding data of 284 late preterm infants were collected. Body composition was evaluated at term-corrected age by air displacement plethysmography. The effect of human milk feeding on fat-free mass and fat mass content was evaluated using multiple linear regression analysis; (3) Results: Human milk was fed to 68% of the infants. According to multiple regression analysis, being fed any human milk at discharge and at  term-corrected and being fed exclusively human milk at term-corrected age were positively associated with fat-free mass content(β = -47.9, 95% confidence interval (CI) = -95.7; -0.18; p = 0.049; β = -89.6, 95% CI = -131.5; -47.7; p < 0.0001; β = -104.1, 95% CI = -151.4; -56.7, p < 0.0001); (4) Conclusion: Human milk feeding appears to be associated with fat-free mass deposition in late preterm infants. Healthcare professionals should direct efforts toward promoting and supporting breastfeeding in these vulnerable infants.

The prevalences of child obesity and overweight are increasing worldwide and are a significant public health issue, particularly in terms of long-term cardiovascular risk profiles, which continue into adulthood unless obesity is reversed. Accurately identifying trends and at-risk subgroups is crucial to correctly target public health initiatives. The objective of this study was to examine changes in the prevalences of child obesity and underweight in Spain from 1983 to 2011 taking into consideration both age and birth year. A series of cross-sectional studies representative of the pediatric population in Spain between 1987 and 2011 was used to calculate the prevalence and trends of excess weight and underweight in girls and boys aged 2 to 14 years per survey year and per birth year. The overall prevalence of overweight and obesity remained relatively stable. The prevalence of overweight in boys aged 10 to 14 years increased from 13.9% to 22.2%. The prevalence of obesity in girls aged 2 to 5 years decreased from 30% to 19.8%, whereas the prevalence of underweight in this group increased from 13.7% to 22.6%. Child obesity trends in Spain over the last 2 decades appear to be stable with some fluctuations, but the trends differ depending on age and sex, and have stabilized at too high a level. The prevalence of underweight also appears to have increased and should be considered alongside excess weight when designing and implementing child health and weight measures.

The aim of this study was to evaluate KL-6 and CC16 levels and their correlation with neurodevelopmental outcome among very low birth weight pre-term infants at 12 months corrected age. This prospective cohort study was performed from 2011 to 2013 by enrolling pre-term neonates of gestational age ≤ 32 weeks and birth weight ≤ 1500 g. Serum KL-6 and CC16 levels were determined 7 days after birth and their correlation with neurodevelopment was evaluated using Gesell Mental Developmental Scales. Of the 86 eligible pre-term infants, 63 completed follow-up, of which 15 had bronchopulmonary dysplasia. At 12 months corrected age, 49 infants had favorable outcomes and 14 infants had poor neurodevelopmental outcome. KL-6 levels were higher and CC16 levels were lower in infants with poor neurodevelopmental outcome compared with those infants who had favourable neurodevelopmental outcome. Serum KL-6 levels less than 90.0 ng/ml and CC16 levels greater than 320.0 pg/ml at 7 days of life were found to be predictive of a favourable outcome at 12 months corrected age. These biological markers could predict neurodevelopmental outcome at 12 months corrected age in very low birth weight premature infants, and help the clinician plan early therapeutic interventions to minimize or avoid poor neurodevelopmental outcome.

Spinal deformities that require ≥5 fusion levels are difficult and challenging for both the surgeon and patient. Corrections of moderate to severe deformities have been shown to improve patient-reported outcomes (PROs), and provide patients with a better quality of life. Self-image is an important PRO because it sheds insight into the patient's perception of health, as well as serving as a proxy of satisfaction for patients with spine deformity undergoing corrective surgery. However, with an aging population, the impact of age on long-term change in self-image is unknown. The aim of this study is to determine the effects of age on self-image 5 years after undergoing an elective complex spinal fusion (≥5 levels). This was a retrospective analysis of prospectively collected data of 55 adult patients (≥18 years old) undergoing ≥5 levels of spinal fusion to the sacrum with iliac fixation from January 2002 to December 2008. Patients were grouped by age: young (<60 years old) and older (≥60 years old). Patient demographics, comorbidities, preoperative variables (sagittal and Cobb angles) and postoperative complication rates were collected. All patients had prospectively collected outcome measures and a minimum of 5 years follow-up. PRO instrument SRS-22r (function, self-image, mental health, and pain) was completed before surgery then at follow-up (at least 5 years after surgery). The primary outcome investigated in this study was the change in self-image after surgery. Baseline characteristics and preoperative variables were similar in both cohorts. There were no significant differences in intraoperative variables, including the mean ± standard deviation number of fusion levels between the cohorts (young, 11.2 ±4.3 vs. older, 12.1 ± 4.0; P = 0.42). Complication rates were similar between the cohorts, with no significant differences in the types of complications (young, 29.63% vs. older, 25.0%; P = 0.77). There were no significant differences in

Vision impairment and corrective considerations of civil airmen.

Civil aviation is a major commercial and technological industry in the United States. The Federal Aviation Administration (FAA) is responsible for the regulation and promotion of aviation safety in the National Airspace System. To guide FAA policy changes and educational programs for aviation personnel about vision impairment and the use of corrective ophthalmic devices, the demographics of the civil airman population were reviewed. Demographic data from 1971-1991 were extracted from FAA publications and databases. Approximately 48 percent of the civil airman population is equal to or older than 40 years of age (average age = 39.8 years). Many of these aviators are becoming presbyopic and will need corrective devices for near and intermediate vision. In fact, there has been approximately a 12 percent increase in the number of aviators with near vision restrictions during the past decade. Ophthalmic considerations for prescribing and dispensing eyewear for civil aviators are discussed. The correction of near and intermediate vision conditions for older pilots will be a major challenge for eye care practitioners in the next decade. Knowledge of the unique vision and environmental requirements of the civilian airman can assist clinicians in suggesting alternative vision corrective devices better suited for a particular aviation activity.

Uncorrected refractive errors are a leading cause of visual disability globally. This population-based study was done to estimate the prevalence of uncorrected refractive errors in adults aged 30 years and above of village Pawakah, Khyber Pakhtunkhwa (KPK), Pakistan. It was a cross-sectional survey in which 1000 individuals were included randomly. All the individuals were screened for uncorrected refractive errors and those whose visual acuity (VA) was found to be less than 6/6 were refracted. In whom refraction was found to be unsatisfactory (i.e., a best corrected visual acuity of <6/6) further examination was done to establish the cause for the subnormal vision. A total of 917 subjects participated in the survey (response rate 92%). The prevalence of uncorrected refractive errors was found to be 23.97% among males and 20% among females. The prevalence of visually disabling refractive errors was 6.89% in males and 5.71% in females. The prevalence was seen to increase with age, with maximum prevalence in 51-60 years age group. Hypermetropia (10.14%) was found to be the commonest refractive error followed by Myopia (6.00%) and Astigmatism (5.6%). The prevalence of Presbyopia was 57.5% (60.45% in males and 55.23% in females). Poor affordability was the commonest barrier to the use of spectacles, followed by unawareness. Cataract was the commonest reason for impaired vision after refractive correction. The prevalence of blindness was 1.96% (1.53% in males and 2.28% in females) in this community with cataract as the commonest cause. Despite being the most easily avoidable cause of subnormal vision uncorrected refractive errors still account for a major proportion of the burden of decreased vision in this area. Effective measures for the screening and affordable correction of uncorrected refractive errors need to be incorpora'ted into the health care delivery system.

Age correction in cognitive, linguistic, and motor domains for infants born preterm: an analysis of the Bayley Scales of Infant and Toddler Development, Third Edition developmental patterns.

To verify whether it is appropriate to use age correction for infants born preterm in all the developmental domains (cognitive, linguistic, and motor) considered by the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). Seventy-three infants born preterm (26-35wks) without major neurological sequelae and 67 infants born at term were assessed at 12 months (corrected age for infants born preterm). The performance of the infants born preterm was assessed with two different evaluations: scores based on uncorrected age and scores based on corrected age. The developmental trends of infants born at term and infants born preterm differ across domains. Statistical analysis shows that age correction produces an overrated estimate of motor performance (12.5 points [95% confidence interval 9.05-16.01]) but not of cognitive performance. Given the broad use of the Bayley-III by psychologists and paediatricians, these results are important in the early diagnosis of developmental difficulties for children born preterm. Correction for gestational age should be applied for the cognitive domain only; whereas for the motor domain, chronological age should be used. No clear data emerged for language. Age correction with Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) for infants born preterm should be applied differently in cognitive, language, and motor domains. Using corrected age with Bayley-III, the motor skills are overrated. Correction for preterm births adequately measures cognitive skills. No clear indication emerged about language skills. © 2018 Mac Keith Press.

Introduction The development of overweight is often measured with the body mass index (BMI). During childhood the BMI curve has two characteristic points: the adiposity rebound at 6 years and the BMI peak at 9 months of age. In this study, the associations between the BMI peak and body composition measures and blood pressure at age 5–6 years were investigated. Methods Measurements from the Amsterdam Born Children and their Development (ABCD) study were available for this study. Blood pressure (systolic and diastolic) and body composition measures (BMI, waist-to-height ratio, fat percentage) were gathered during a health check at about 6 years of age (n = 2822). All children had multiple BMI measurements between the 0–4 years of age. For boys and girls separately, child-specific BMI peaks were extracted from mixed effect models. Associations between the estimated BMI peak and the health check measurements were analysed with linear models. In addition, we investigated the potential use of the BMI at 9 months as a surrogate measure for the magnitude of the BMI peak. Results After correction for the confounding effect of fetal growth, both timing and magnitude of the BMI peak were significantly and positively associated (p<0.001) with all body composition measures at the age of 5–6 years. The BMI peak showed no direct association with blood pressure at the age 5–6 year, but was mediated by the current BMI. The correlation between the magnitude of the BMI peak and BMI at 9 months was approximately 0.93 and similar associations with the measures at 5–6 years were found. Conclusion The magnitude of the BMI peak was associated with body composition measures at 5–6 years of age. Moreover, the BMI at 9 months could be used as surrogate measure for the magnitude of the BMI peak. PMID:24324605

Preterm infants present higher risk of non-optimal neurodevelopmental outcome. Fetal and postnatal growth, in particular head circumference (HC), is associated with neurodevelopmental outcome. We aimed to calculate the relationship between HC at birth, HC delta Z-score (between birth and hospital discharge), and non-optimal neurodevelopmental outcome at 2 years of corrected age in preterm infants. Surviving infants born ≤34 weeks of gestation were included in the analysis. The relationship between the risk of being non-optimal at 2 years and both HC at birth and HC growth was assessed. The 2 Z-scores were considered first independently and then simultaneously to investigate their effect on the risk of non-optimality using a generalized additive model. A total of 4,046 infants with both HC measures at birth and hospital discharge were included. Infants with small HC at birth (Z-score <-2 SD), or presenting suboptimal HC growth (dZ-score <-2 SD), are at higher risk of non-optimal neurodevelopmental outcome at 2 years (respectively OR 1.7 [95% CI 1.4-2] and OR 1.4 [95% CI 1.2-1.8]). Interestingly, patients cumulating small HC Z-score at birth (-2 SD) and presenting catch-down growth (HC dZ-score [-2 SD]) have a significantly increased risk for neurocognitive impairment (OR >2) while adjusting for gestational age, twin status, sex, and socioeconomic information. HC at birth and HC dZ-score between birth and hospital discharge are synergistically associated to neurodevelopmental outcome at 2 years of corrected age, in a population-based prospective cohort of preterm infants born ≤34 weeks of gestation. © 2017 S.

Cholelithiasis is very common in patients with sickle cell disease (SCD) and is responsible for recurrent attacks of abdominal pain. The ideal management, especially for children, remains controversial. The purpose of the present study was to evaluate the safety and outcome of mini-laparoscopic cholecystectomy (MLC) in young children under age of 10 years with SCD. A prospective study was carried out of 75 children with SCD under 10 years of age with recurrent abdominal pains seen between August 2001 and March 2004 at Armed Forces Hospital, Khamis Mushayt, Saudi Arabia, who were screened for cholelithiasis. Twelve (16%) of the 75 children were found to have gallstones. The mean age was 7.8 years (range 4-9 years). All 12 children underwent MLC. Anaemia was corrected preoperatively in all the patients. Operative time, intraoperative complications, hospital stay, and postoperative recurrent abdominal pain were recorded. The mean operating time was 46.5 min (range: 35-65 min). Intraoperative cholangiogram failed in two children due to narrow cystic ducts. The mean hospital stay was 2.1 days (range: 2-4 days). No patient required intra-abdominal drain. The mean follow-up period was 13.4 months (range: 4-24 months). The only postoperative complication was deep jaundice 1 month postoperatively due to cholestasis, and this responded to medical treatment. None of the children had recurrent abdominal pain after MLC. Mini-laparoscopic cholecystectomy is a safe surgical procedure for the management of cholelithiasis in children with SCD and leads to improvement in the quality of life by decreasing the frequency of recurrent abdominal pain.

Tetralogy of Fallot became a correctable malformation on August 31, 1954, and from that data through 1960, 106 patients (ages 4 months-45 years) who underwent open repairs at the University of Minnesota and were discharged, have been followed (99% complete) until death or for 26-31 years (mean: 23.7 years, 2424 patient years). The purposes of this study were to determine survival, morbidity, hemodynamics, educational/employment attainments, and relation of these to surgical technics. Operations were done by cross circulation (6 patients) and bubble oxygenator (100 patients). This group had the first uses of patch ventricular septal defect closure, outflow root, infundibuloplasty, atresia correction, ischemic arrests, and pacemakers among other innovations. Twenty-one (of 105 patients) have died during the followup: eight deaths in the first 10 years, 12 between 10 and 20 years, and 1 greater than 20 years. The causes of death were sudden (5), accidental (4), congestive failure (2), reoperation (2), suicide (2), and other (2). Actuarial survival at 30 years was 77%. Late complications were ten reoperations, five arrhythmias, and one endocarditis. Actuarial freedom from reoperations at 30 years was 91%. Cardiac recatheterizations in 62 patients disclosed only 10 with residual shunts. Peak right ventricular systolic pressures were less than 40 mmHg (34 patients), 41-60 mm (2 patients), 61-70 mm (4 patients), greater than 71 mm (4 patients). Thirty-four patients (32%) completed college, ten of these completed graduate school (5 masters degrees, 2 M.D.'s, 2 Ph.D.'s, 1 lawyer). Fifteen others attended college, and nine received technical school diplomas. Forty patients (18 men, 22 women) had progeny, with 82 (93%) live births and six major cardiac defects (7.3%). In summary, complete repair gave excellent late results in this group cared for very early in the open heart era. Survivors led productive lives without restrictions in education and employment.

To study the 5-year incidence of visual impairment and its causes and risk factors, in the middle-aged Iranian sample of the Shahroud Eye Cohort Study (ShECS). Data from subjects who had participated in both phases of the ShECS were used to determine age- and sex-specific incidence rates of visual impairment using the World Health Organization (WHO) definitions for bilateral low vision (visual acuity, VA, >0.5 and ≤1.3 LogMAR in the better eye) and blindness (VA worse than 1.3 LogMAR in the better eye). Risk ratios (RR) and 95% confidence intervals (CIs) were calculated using multivariable log-binomial regression. Of the 5079 ShECS I survivors, 4737 (93.3%) completed the 5-year follow-up. Their mean age at baseline was 50.9 ± 6.2 years, and 58.9% were female. The incidence of visual impairment was 1.12% (95% CI 0.82-1.42%) by presenting VA and 0.19% (95% CI 0.07-0.32%) by best-corrected VA; leading causes of the former were uncorrected refractive error (81.3%) and diabetic retinopathy (15.1%). In the multivariable model, risk factors for incident visual impairment by presenting VA were older age (RR 1.05, p = 0.044), lower education (RR 0.89, p = 0.002), and diabetes (RR 3.74, p < 0.001). This is the first incidence study of visual impairment in a middle-aged Iranian population. Since age is a major risk factor, the number of visually impaired is expected to increase as the population ages, and less treatable causes such as diabetic retinopathy begin to surface. Measures for tackling uncorrected refractive error and enhancing diabetes screening and preventive programs are recommended.

Correcting for diffusion in carbon-14 dating of ground water

USGS Publications Warehouse

Sanford, W.E.

1997-01-01

It has generally been recognized that molecular diffusion can be a significant process affecting the transport of carbon-14 in the subsurface when occurring either from a permeable aquifer into a confining layer or from a fracture into a rock matrix. An analytical solution that is valid for steady-state radionuclide transport through fractured rock is shown to be applicable to many multilayered aquifer systems. By plotting the ratio of the rate of diffusion to the rate of decay of carbon-14 over the length scales representative of several common hydrogeologic settings, it is demonstrated that diffusion of carbon-14 should often be not only a significant process, but a dominant one relative to decay. An age-correction formula is developed and applied to the Bangkok Basin of Thailand, where a mean carbon-14-based age of 21,000 years was adjusted to 11,000 years to account for diffusion. This formula and its graphical representation should prove useful for many studies, for they can be used first to estimate the potential role of diffusion and then to make a simple first-order age correction if necessary.It has generally been recognized that molecular diffusion can be a significant process affecting the transport of carbon-14 in the subsurface when occurring either from a permeable aquifer into a confining layer or from a fracture into a rock matrix.

To investigate crowding ratios in children with a visual impairment due to ocular disease (n = 58) and normally sighted children (n = 75) aged 4 to 8 years using several variants of two clinically available tests with different optotype spacing (fixed or proportional to the optotype size). Crowding ratios, calculated by dividing the single acuity by the linear acuity, were measured binocularly with the C-test and the LH line chart. Ratios >1.00 indicate crowding. The charts with fixed spacing revealed significantly higher crowding ratios for visually impaired children than normally sighted children (both for measurements at 40 cm and 5 m). The age-related reduction of the crowding ratios seen in normally sighted children when tested with near-vision charts with fixed spacing was not present in the visually impaired group. Visually impaired children with nystagmus showed higher crowding ratios than visually impaired children without nystagmus. The chart with proportional intersymbol spacing (ISS) did not reveal differences between the normally sighted and visually impaired children; nor did it show group, age, or nystagmus effects. Visually impaired children showed higher crowding ratios than normally sighted children when measured with charts with fixed ISS. This study illustrates that test design and target/flanker interference as a manifestation of crowding are critical issues to bear in mind when assessing crowding ratios in children.

Low levels of physical activity in childhood are associated with clustering of cardiovascular risk factors (CVRF) as predisposition for atherosclerosis. We assessed the association between sports engagement and age at first myocardial infarction (MI) in a cohort of men under 55 years of age. The Bern percutaneous coronary intervention Registry (NCT 02241291) was analyzed from March 2009 until January 2012. Male patients with first MI, age 18 to 54 years and body mass index ≤25kg/m2 were included. Patients were stratified into two groups based on their starting age with organized sports ≥1 h/week outside school (EARLY: <18, CONTROL: ≥18 years or never). We assessed age at time of first MI, CVRF, and volume of sports training. Of 4,394 consecutive patients, 123 fulfilled the inclusion criteria (EARLY n = 81, CONTROL n = 42). Age at the time of first MI was 3 years younger in the EARLY compared to the CONTROL group (46.8±6.0 vs. 49.8±4.6 years, p = 0.006). Total lifetime training hours, and average yearly training hours, both, before and after age 18, were significantly greater in the EARLY group. Years of training <18 years were weakly inversely correlated with age at first MI (r2 = 0.075, p = 0.002). The proportion of sports-related MI was not different between EARLY and CONTROL (13.6% vs. 11.9%). Patients in the EARLY group had fewer CVRF (2 vs. 3; p = 0.001). Prevalence of smoking was equally high in both groups (63.0% and 64.3%). In our patients aged 54 and younger, the first MI occurred 3 years earlier in those who started regular sports activity before age 18, despite a more active lifestyle and favorable CVRF profile.

AIMS--To investigate how young children develop the ability to undergo a visual field evaluation using regular automated perimetry. METHODS--The study included 42 normal girls aged 5, 6, 7, and 8 years. Twelve locations in the 15 degrees eccentricity were tested in one eye, using an Octopus 2000R perimeter with a two level strategy. False positive and false negative catch trials were presented. The examination was performed three times in succession. Before the examination procedure, a specially designed programme was conducted for progressive familiarisation. RESULTS--During the familiarisation procedure, it was found that all of the 5-year-old children, seven of the 6-year-old children, and three of the 7-year-old children were unable to perform immediately, and correctly, the instructions given during the familiarisation phase; these children took from 30 seconds to 3 minutes to comply with the examiner's requests. With the exception of one 5-year-old child, all tested subjects completed the planned procedure. The mean proportion of false negative answers in catch trials was 1.6%. The mean proportion of false positive answers was 12.2%. The quadratic dependency on age suggested by the averages was not significant (F(3,116) = 0.88; p = 0.45). Detection stimulus improved with age, as shown by the fact that probability of perceiving dim stimulus increases significantly (F(3,116) = 12.68; p < 0.0001). CONCLUSION--Children did remarkably well regarding both the duration of the examination and the reliability of the answers. A preliminary familiarisation phase with a specially designed adaptation programme was found to be mandatory with children aged 7 or under. To our knowledge, this is the first time that such an investigation has been performed. PMID:8759261

Background The high prevalence of smoking (80%) in Greek correctional institutions is anticipated to result in high prevalence of COPD in such settings. Aim The aim of the Greek obstructive luNg disease epidemiOlogy and health economics Study In corrective institutionS (GNOSIS) is to determine the prevalence of smoking and COPD among inmates and to assess the health-related quality of life. Methods GNOSIS, a cross-sectional epidemiological study, was conducted between March 2011 and December 2011 in seven correctional institutions in Greece. Results A total of 552 participants, 91.3% male, median age of 43.0 years (interquartile range: 35–53), were enrolled. COPD prevalence was 6.0% and was found to increase with age (18.6% among those ≥60 years), length of prison stay, and length of sentence. Of the participants diagnosed with COPD, 36.4% were diagnosed with Global initiative for chronic Obstructive Lung Disease (GOLD) stage I and 51.5% were diagnosed with stage II. Dyspnea severity was assessed as grades 0–1 on the medical research council dyspnea scale for 88.3%, while 31% reported ≥2 COPD exacerbations in the past year. Seventy-nine percent of the total number of the participants were smokers, with a median smoking of 20.0 cigarettes per day, while 42.9% were assessed as having a strong addiction to nicotine. The median EuroQol visual analog scale score was 70.0 (interquartile range: 60.0–90.0). Problems in the dimension of anxiety/depression were reported by 82.8%. Conclusion The results of the study support the notion that the prevalence of COPD among inmates of Greek correctional institutions may increase in the following years. The findings underscore the importance of taking actions to limit COPD prevalence and its risk factors in the Greek correctional system. PMID:26929618

To evaluate the radiological and clinical outcomes of the corrective surgery for patients with moderate to severe focal kyphosis in thoracolumbar spine. Fifty-seven patients with moderate to severe focal kyphosis of the thoracolumbar spine underwent apical segmental resection osteotomy with dual axial rotation correction at our hospital. There were 30 male and 27 female patients. The mean age was 34.3 years. The kyphosis level radiographs were obtained from each patient before surgery, immediately after surgery and at follow-up. Local kyphosis and scoliosis Cobb angles were measured. Full-spine standing radiographs were obtained before surgery and at follow-up, and the spine sagittal and coronal balance were evaluated. The height of patients, the Frankel grading system for neurological functions, the Oswestry disability index for life quality, the visual analogue score for back pain and the patient satisfactory index for satisfaction to surgery were applied before surgery and at follow-up. The radiological and clinical outcomes were further analyzed in different sub-groups of patients according to etiology, severity of kyphosis, age, level of kyphosis apex, Frankel grade before surgery, and complications. The average follow-up time of patients was 46.1 months. The average kyphosis angle reduced from 94.6° before surgery to 31.0° immediately after surgery, and remained at 34.4° at follow-up. The sagittal balance of the spine, height of patients, Frankel grading, Oswestry disability index and visual analogue score were improved. The patient satisfactory index (PSI) showed a satisfied rate of 91.2%. The correction rate was significantly higher in patients with kyphosis angle less than 95° and age less than 35 years. The clinical improvement rate was significantly higher in patient with kyphosis apex at lower thoracic spine or thoracolumbar segment, Frankel grade E before surgery and no complication group.

The aim of the study was to evaluate the prevalence of under-corrected refractive error among elderly Chinese in the Beijing area. The population-based, cross-sectional, cohort study comprised 4,439 subjects out of 5,324 subjects asked to participate (response rate 83.4%) with an age of 40+ years. It was divided into a rural part [1,973 (44.4%) subjects] and an urban part [2,466 (55.6%) subjects]. Habitual and best-corrected visual acuity was measured. Under-corrected refractive error was defined as an improvement in visual acuity of the better eye of at least two lines with best possible refractive correction. The rate of under-corrected refractive error was 19.4% (95% confidence interval, 18.2, 20.6). In a multiple regression analysis, prevalence and size of under-corrected refractive error in the better eye was significantly associated with lower level of education (P<0.001), female gender (P<0.001), and age (P=0.001). Under-correction of refractive error is relatively common among elderly Chinese in the Beijing area when compared with data from other populations.

Apert foot anomalies may cause severe problems such as pain and development of callus formation related to weight redistribution, problems with footwear, and gait disturbances that may limit their daily activities. The main purpose of this study was to review our experience with distraction osteogenesis for the correction of brachymetatarsia and the great toe angulation of the patients with Apert syndrome. This study retrospectively reviewed 7 patients (14 extremities) followed up for Apert syndrome who underwent distraction for the correction of bilateral congenital brachymetatarsia and angulation of the great toe between 2004 and 2008. Correction of the metatarsal inclination angle, the medial angulation of the great toe, the percentage of lengthening, and lengthening rates of distracted bones were evaluated. Patients ranged in age from 4 to 8 years at the distraction operation, with a mean age of 5.4±1.3 years, and the average length of follow-up was 86.6±21.0 months. The length of the first metatarsal bone increased significantly from the average length of 32.6±5.7 mm to an average of 46.7±6.5 mm (P<0.001). The mean lengthening rate and lengthening percentages of distracted bones were 0.4%±0.1%/month and 30.2%±6.4%/month, respectively. Preoperative and postoperative metatarsal inclination angles were at a mean of 43.8±5.12 and 32.6±3.8, respectively, and the correction of metatarsal inclination was considered as statistically significant (P<0.001). The mean angulation of the great toe reduced significantly from 49.8±11.76 to 13.2±8.5 degrees after distraction (P<0.001). Minor complications such as pin loosening, pin-tract infection, and early union that required reoperation were observed in 5 extremities (35.7%). Anatomic features of Apert foot may lead to complaints that may limit patients' daily activities and require as much attention as associated hand and craniofacial anomalies. Distraction appears to be an effective and safe approach for the

Prevention of myopia by partial correction of hyperopia: a twins study.

PubMed

Medina, Antonio

2018-04-01

To confirm the prediction of emmetropization feedback theory that myopia can be prevented by correcting the hyperopia of a child at risk of becoming myopic. We conducted such myopia prevention treatment with twins at risk. Their hyperopia was partially corrected by one half at age 7 and in subsequent years until age 16. Hyperopia progressively decreased in all eyes as expected. None of the twins developed myopia. The spherical equivalent refractions of the followed eyes were +1 and +1.25 D at age 16. Feedback theory accurately predicted these values. The treatment of the twins with partial correction of their hyperopia was successful. Prevention of myopia with this technique is relatively simple and powerful. The use of this myopia prevention treatment has no adverse effects. This prevention treatment is indicated in children with a hyperopic reserve at risk of developing myopia.

The life expectancy of persons with Prader-Willi syndrome (PWS) has increased in recent years. Because of the paucity of reports on older persons with PWS, the natural history, the onset, and type of age-related problems are poorly understood. Twelve persons with a genetically confirmed diagnosis of PWS aged over 50 years are described (4 deletion; 8 mUPD). Data on physical, behavioral, psychiatric, and aging characteristics were collected through semi-structured interviews with the individuals with PWS and their main carers. Cardiovascular diseases, diabetes, dermatological, and orthopedic problems were common physical complaints in older people with PWS. Functioning in activities of daily living, psychological functioning, physical functions, and care dependence were substantially worse in the older age group (50+) compared to the control group (18-49 years). Seven out of eight persons with mUPD had a history of psychiatric illness. Behavioral problems were observed in the older age group. Given the combination of age-related physical morbidity, physical appearance, behavioral and psychiatric problems, and functional decline in our cohort, we hypothesize that premature aging occurs in PWS. The care for older people with PWS requires a lifespan approach that recognizes the presence, progression, and consequences of specific morbidity. Special medical surveillance of people with PWS from 40 years onwards would ensure that intervention and support is offered with respect to specific areas of decline at the earliest possible time.

Consecutive patients with CHD in a tertiary center in South India were evaluated for nutritional status before and 2 years after corrective intervention. Anthropometry was performed at presentation and every 6 months for 2 years, and z scores were compared. Malnutrition was defined as a weight-for-age, height-for-age, and weight/height z score <-2. Determinants of malnutrition were entered into a multivariate logistic regression analysis model. Of 476 patients undergoing corrective intervention (surgical: 344; catheter-based: 132) z scores of less than -2 for weight for age, height for age, and weight/height were recorded in 59%, 26.3%, and 55.9% of patients, respectively, at presentation. On follow-up (425 patients [92.5% of survivors; 20.63 +/- 13.1 months of age]), z scores for weight for age and weight/height improved significantly from the baseline (weight: -1.42 +/- 1.03 vs -2.19 +/- 1.16; P < .001; weight/height: -1.15 +/- 1.25 vs -2.09 +/- 1.3; P < .001). Height-for-age z scores were not significantly different. Malnutrition persisted in 116 (27.3%) patients on follow-up and was associated with a birth weight of corrective surgery or intervention. Persistent malnutrition after corrective intervention is predicted by nutritional status at presentation, birth weight, and parental anthropometry.

To report successful therapy for anisometropic and strabismic amblyopia initiated after age 7 years. A consecutive series of 36 compliant children older than 7 years (range, 7.0 to 10.3 years; mean, 8.2 years) at initiation of amblyopia therapy for anisometropic (19 patients; mean age, 8.3 years), strabismic (9 patients; mean age, 8.0 years), or anisometropic and strabismic (8 patients; mean age, 8.0 years) amblyopia was studied. Initial (worst) visual acuities were between 20/50 and 20/400 (log geometric mean, -0.83 [antilog, 20/134] for all patients; -0.88 [antilog, 20/151] for anisometropic patients; -0.70 [antilog, 20/100] for strabismic patients; and -0.88 [antilog, 20/151] for anisometropic and strabismic patients). Initial (worst) binocularity was absent or reduced in all cases. Therapy consisted of (1) full-time standard occlusion (21 patients; mean age, 8.0 years), (2) total penalization (7 patients; mean age, 7.8 years), or (3) full-time occlusive contact lenses (8 patients; mean age, 8.8 years). Final (best) visual acuities were between 20/20 and 20/30 for all 36 patients. Final (best) binocularity was maintained or improved for 22 (61%) of 36 patients, including 16 anisometropic patients (84%), 2 strabismic patients (22%), and 4 anisometropic and strabismic patients (50%). Given compliance, therapy for anisometropic and strabismic amblyopia can be successful even if initiated after age 7 years. Arch Ophthalmol. 2000;118:1535-1541

Objective. The aim of this study was to evaluate the effect of maternal age on prenatal and obstetric outcome in multiparaous women. Materials and Methods. A retrospective case control study was conducted, including women aged 40 years and over (study group, n = 97) who delivered at 20 week's gestation or beyond and women aged 20–29 years (control group, n = 97). Results. The mean age of women in the study group was 41.2 ± 1.7 years versus 25.4 ± 2.3 years in the control group. Advanced maternal age was associated with a significantly higher rate of hypertension, diabetes mellitus, fetal complication, and 5-minute Apgar scores <7 (P < 0.05). Caeserean section rate, incidence of placental abruption, preterm delivery, and neonatal intensive care unit admission were more common in the older group, but the differences were not statistically significant. Conclusions. Advanced maternal age is related to maternal and neonatal complications. PMID:25954770

The nationwide 'German Health Interview and Examination Survey for Children and Adolescents' (KiGGS), conducted in 2003-2006, showed an increase in the prevalence rates of overweight and obesity compared to the early 1990s, indicating the need for regular monitoring. Recently, a follow-up-KiGGS Wave 1 (2009-2012)-was carried out as a telephone-based survey, providing parent-reported height and weight from 5155 children aged 4-10 years. Since parental reports lead to a bias in prevalence rates of weight status, a correction is needed. From a subsample of KiGGS Wave 1 participants, measurements for height and weight were collected in a physical examination. In order to correct prevalence rates derived from parent reports, weight status categories based on parent-reported and measured height and weight were used to estimate a correction formula according to an established procedure. The corrected prevalence rates derived from KiGGS Wave 1 for overweight, including obesity, in children aged 4-10 years in Germany showed that stagnation is reached compared to the KiGGS baseline study (2003-2006). The rates for overweight, including obesity, in Germany have levelled off. However, they still remain at a high level, indicating a need for further public health action. What is Known: • In the last decades, prevalence of overweight and obesity has risen. Now a days, the prevalence seems to be stagnating. • In Germany, prevalence estimates of overweight and obesity are only available from regional or non-representative studies. What is New: • This article gives an update for prevalence rates of overweight and obesity amongst children aged 4-10 years in Germany based on a nationwide and representative sample. • Results show that stagnation in prevalence rates for overweight in children in Germany is reached.

Purpose Eyes with age-related macular degeneration (AMD) often harbor pathological changes in the retinal periphery and perimacular region. These extramacular changes have not been well classified, but may be phenotypically and functionally relevant. The purpose of this study was to demonstrate a novel grid to systematically study peripheral retinal abnormalities in AMD using geometric distortion-corrected ultra-widefield (UWF) imaging. Methods This is a cross-sectional observational case series. Consecutive patients with AMD without any other coexisting vitreoretinal disease and control patients over age 50 without AMD or any other vitreoretinal disease were imaged using Optos 200 Tx. Captured 200° UWF images were corrected for peripheral geometric distortion using Optos transformation software. A newly developed grid to study perimacular and peripheral abnormalities in AMD was then projected onto the images. Results Peripheral and perimacular changes such as drusen, retinal pigment epithelium changes and atrophy were found in patients with AMD. The presented grid in conjunction with geometric distortion-corrected UWF images allowed for systematic study of these peripheral changes in AMD. Conclusion We present a novel grid to study peripheral and posterior pole changes in AMD. The grid is unique in that it adds a perimacular zone, which may be important in characterizing certain phenotypes in AMD. Our UWF images were corrected for geometric peripheral distortion to accurately reflect the anatomical dimensions of the retina. This grid offers a reliable and reproducible foundation for the exploration of peripheral retinal pathology associated with AMD. PMID:29184386

Inadequate nutrition supply during the period of intrauterine growth and the first year of life leads to persistent metabolic changes and provokes development of various diseases. Тo compare physical development, body composition, and hormonal status (insulin, insulin-like growth factor-1 (IGF-1), somatotropic hormone (STH), C-Peptide, cortisol) indices in premature infants born with intrauterine growth restriction (IUGR) at the term corrected age with the same indices in mature infants with IUGR and premature infants with weight appropriate for their gestational age (GA). А crossover study of anthropometric measures, body composition and growth hormones changes assessment was carried out. It included 140 premature infants with weight appropriate for their GA, 58 premature infants with IUGR and 64 mature infants with IUGR. Anthropometric measures were assessed with Fenton and Anthro growth charts (WHO, 2009); body composition was studied with the air plethysmography method (РЕA POD, LMi, USA). Level of hormones in blood serum was assessed with biochemical methods. It is found that anthropometric measures in premature infants with weight appropriate for their GA and premature infants with IUGR at the term corrected age did not have any significant differences while premature infants with IUGR tended to have lower weight. Studying body composition we found that both groups of premature infants had slightly higher level of fat mass in comparison with mature infants. High concentration of insulin, cortisol, IGF-1, and C-peptide was found in premature and mature infants with IUGR. Instead, lower levels of STH was found in infants with IUGR. Formula fed premature infants (comparing to breastfed ones) had higher levels of fat mass, insulin, IGF-1, and C-peptide. Mature infants with IUGR did not tend to have the correlation between levels of fat mass, insulin, IGF-1, C-peptide, and type of feeding. Not only insufficient intrauterine growth but also nutrition pattern

Sensory experience is the basis for learning in infancy. In older children, abnormal sensory reactivity is associated with behavioural and developmental disorders. We hypothesised that in preterm infants, abnormal sensory reactivity during infancy would be associated with perinatal characteristics and correlate with 2-year neurodevelopmental outcomes. We conducted a prospective observational study of infants with birth weight ≤1500 g using the Test of Sensory Function in Infants (TSFI) in the first year. Infants with gestational age ≤30 weeks were tested with the Bayley Scales of Infant and Toddler Development III (BSID III) at 24 months. Of the 72 participants evaluated at 4-12 months corrected age (median 8 months), 59 (82%) had a least one TSFI score concerning for abnormal sensory reactivity. Lower gestational age was associated with abnormal reactivity to deep pressure and vestibular stimulation (p<0.001). Poor ocular-motor control predicted worse cognitive and motor scores in early childhood (OR 16.7; p=0.004), but was tightly correlated to the presence of severe white matter injury. Poor adaptive motor function in response to tactile stimuli predicted worse BSID III motor (p=0.01) and language scores (p=0.04) at 2 years, even after adjusting for confounders. Abnormal sensory reactivity is common in preterm infants; is associated with immaturity at birth, severe white matter injury and lower primary caregiver education; and predicts neurodevelopmental delays. Early identification of abnormal sensory reactivity of very preterm infants may promote parental support and education and may facilitate improved neurodevelopment.

Relationship between age and elite marathon race time in world single age records from 5 to 93 years

PubMed Central

2014-01-01

Background The aims of the study were (i) to investigate the relationship between elite marathon race times and age in 1-year intervals by using the world single age records in marathon running from 5 to 93 years and (ii) to evaluate the sex difference in elite marathon running performance with advancing age. Methods World single age records in marathon running in 1-year intervals for women and men were analysed regarding changes across age for both men and women using linear and non-linear regression analyses for each age for women and men. Results The relationship between elite marathon race time and age was non-linear (i.e. polynomial regression 4th degree) for women and men. The curve was U-shaped where performance improved from 5 to ~20 years. From 5 years to ~15 years, boys and girls performed very similar. Between ~20 and ~35 years, performance was quite linear, but started to decrease at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference increased non-linearly (i.e. polynomial regression 7th degree) from 5 to ~20 years, remained unchanged at ~20 min from ~20 to ~50 years and increased thereafter. The sex difference was lowest (7.5%, 10.5 min) at the age of 49 years. Conclusion Elite marathon race times improved from 5 to ~20 years, remained linear between ~20 and ~35 years, and started to increase at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference in elite marathon race time increased non-linearly and was lowest at the age of ~49 years. PMID:25120915

One of the fundamentals of 40Ar-39Ar systematics of illite considers the effects of 39Ar recoil (ejection of 39Ar from tiny illite crystallites during the nuclear reaction 39K(n,p)39Ar), for which sample vacuum encapsulation prior to irradiation has been used since the 1990's. This technique separately measures the fraction of recoiled 39Ar and the Ar (39Ar and 40Ar) retained within illite crystals as they degas during step heating in vacuum. Total-gas ages (TGA) are calculated by using both recoiled and retained argon, while retention ages (RA) only involve retained Ar. Observations in numerous natural examples have shown that TGA fit stratigraphic constraints of geological processes when the average illite crystallite thickness (ICT) is smaller than 10nm, and that RA better matches these constrains for larger ICTs. Illite crystals with ICT >50nm show total gas and retention ages within a few My and they are identical, within analytical error, when ICT exceeds 150nm. We propose a new age correction that takes into account the average ICT and corresponding recoil for a sample , with such corrected ages (XCA) lying between the TGA and RA end-member ages. We apply this correction to samples containing one generation of illite and it particularly affects illite populations formed in the anchizone, with typical ICT values between 10-40nm. We analyzed bentonitic samples (S1, S2 and S3) from sites in Cretaceous carbonates in the front of the Monterrey salient in northern Mexico. Four size fractions (<0.05, 0.05-0.2, 0.2-1 & 1-2 μm) were separated, analyzed with XRD and dated by Ar-Ar. XRD analysis provides mineralogic characterization, illite polytype quantification, and illite crystallite thickness (ICT) determination using half-height peak width (illite crystallinity) and the Scherrer equation. All samples contain illite as the main mineral phase, ICT values between 8-27nm, from fine to coarser grain size fractions. Ages show a range in TGA among the different size

To determine whether interceptive orthodontics prior to the age of 11 years is more effective than later treatment in the short- and long-term. Multiple electronic databases were searched, authors were contacted as required and reference lists of included studies were screened. Randomised and quasi-randomised controlled trials were included, comparing children under the age of 11 years requiring interceptive orthodontic correction for a range of occlusal problems, to an untreated or positive control group. Data extraction and quality assessment were performed independently and in duplicate. Twenty-two studies were potentially eligible for meta-analysis, the majority related to growth modification. Other outcomes considered included correction of unilateral posterior crossbite, anterior openbite, extractions and ectopic maxillary canines. Meta-analysis was possible for 11 comparisons. For Class II correction in the short-term, meta-analyses demonstrated a statistically significant reduction in ANB (-1.4 degrees, 95 CI: -2.17, -0.64) and overjet (-5.81mm, 95 CI: -6.37, -5.25) with both functional appliances and headgear versus control. In the long-term, however, statistical significance was not found for the same outcomes. Treatment duration was prolonged with both functional appliances (6.85 months, 95 CI: 3.24, 10.45) and headgear (12.47 months, 95 CI: 8.67, 16.26) compared to adolescent treatments. Meta-analyses were not possible for comparisons of other interceptive treatments due to heterogeneity and methodological limitations. The results suggest a lack of evidence to prove that early treatment carries additional benefit over and above that achieved with treatment commencing later; however, this does not necessarily imply that early treatment is ineffective. Further high quality trials are required to assess the effectiveness of early treatment compared to later intervention. Interceptive orthodontics is variously recommended for a range of malocclusions both

OBJECTIVE: To analyze adherence to the recommended iron, zinc and multivitamin supplementation guidelines for preemies, the factors associated with this adherence, and the influence of adherence on the occurrence of anemia and iron, zinc and vitamin A deficiencies. METHODS: This prospective cohort study followed 58 preemies born in 2014 until they reached six months corrected age. The preemies were followed at a referral secondary health service and represented 63.7% of the preterm infants born that year. Outcomes of interest included high or low adherence to iron, zinc and multivitamin supplementation guidelines; prevalence of anemia; and prevalences of iron, zinc, and vitamin A deficiencies. The prevalence ratios were calculated by Poisson regression. RESULTS: Thirty-eight (65.5%) preemies presented high adherence to micronutrient supplementation guidelines. At six months of corrected age, no preemie had vitamin A deficiency. The prevalences of anemia, iron deficiency and zinc deficiency were higher in the low-adherence group but also concerning in the high-adherence group. Preemies with low adherence to micronutrient supplementation guidelines were 2.5 times more likely to develop anemia and 3.1 times more likely to develop zinc deficiency. Low maternal education level increased the likelihood of nonadherence to all three supplements by 2.2 times. CONCLUSIONS: Low maternal education level was independently associated with low adherence to iron, zinc and vitamin A supplementation guidelines in preemies, which impacted the prevalences of anemia and iron and zinc deficiencies at six months of corrected age.

While many studies show a correlation between chronological age and physiological indicators, the nature of this correlation is not fully understood. To perform a comprehensive analysis of the correlation between chronological age and age-related physiological indicators. Physiological aging scores were deduced using principal component analysis from a large dataset of 1,227 variables measured in a cohort of 4,796 human subjects, and the correlation between the physiological aging scores and chronological age was assessed. Physiological age does not progress linearly or exponentially with chronological age: a more rapid physiological change is observed around the age of 55 years, followed by a mild decline until around the age of 70 years. These findings provide evidence that the progression of physiological age is not linear with that of chronological age, and that periods of mild change in physiological age are separated by periods of more rapid aging. © 2015 S.

To our knowledge, quantification of intranasal deposition of aerosol generated by Accuspray(™) (AS) in children has never been published. We hypothesized that deposition would vary significantly with age and with placement of the device within, or outside, of the nostril. We tested these hypotheses in anatomically-correct physical models based on CT scans of 2-, 5-, and 12-year-old children with normal, intranasal airways. Models included a removable anterior nose (AN) with exterior facial features and interior nasal vestibule and nasal valve area and a main nasal airway (MNA), subdivided into upper (superior turbinates and olfactory area), middle (middle turbinates), and lower (inferior turbinates and nasopharynx) thirds. Aerosol was generated from distilled water admixed with (99m)technetium pertechnetate and administered during static airflow by AS inserted inside the right nostril (eight runs/model), or outside the right nostril (six runs/model). Mean aerosol Dv(50) ± standard deviation was 67.8 ± 24.7 μm. Deposition was quantified by 2D gamma scintigraphy and expressed as percentage of the emitted dose. When placed inside the nostril, mean (± standard deviation) deposition within the MNA was significantly less in the 2-year-old, compared to the 5- and 12-year-old, averaging 46.8 ± 33.8% (AN:55.4 ± 29.9%), 75.4 ± 26.7% (AN:23.3 ± 13.6%), and 72.1 ± 18.5% (AN:25.8 ± 18.5%), respectively (p<0.05). When placed outside the nostril, MNA was significantly less in the 2- and 5-year-old compared to the 12-year-old, with 1.4 ± 2.5% (AN:69.7 ± 40.7%), 7.4 ± 9.0% (AN:77.8 ± 32.8%), and 21.1 ± 29.1% (AN:29.2 ± 19.3%), respectively (p<0.05). Deposition in the MNA of all age models was highest when AS was placed inside the nostril (p<0.05). Deposition in the lower third was significantly increased for the 5- and 12-year-old and in the middle third of the 5-year-old when AS was placed inside the nostril. These results indicate that age and device placement

This article provides a review of the first 20 years of Psychology and Aging, the American Psychological Association’s first and only scholarly journal devoted to the topic of aging. The authors briefly summarize its history, its contributions to the study of aging, and its broader status as a scholarly publication. One theme highlighted in our review is the diversity of content in the journal throughout its history. Another is the strong impact that articles published in the journal have had on both basic and applied topics in aging. Efforts to encompass the breadth of topics and methodologies in aging research while retaining excellent quality remain the exciting but essential challenge for Psychology and Aging. PMID:16594786

To examine changes in child car restraint practices in low socioeconomic areas following the introduction of mandatory child car restraint legislation in New South Wales (NSW), Australia. Data from two cross-sectional studies of child car restraint use at pre-schools, early childhood centres and primary schools before and after the introduction of legislating mandatory age-appropriate car restraint use for children up to the age of seven years was used in this analysis. All included observations were from local government areas with socioeconomic status in the lowest 30% of urban Sydney. Children aged 2-5 years were observed in their vehicles as they arrived at observation sites (107 pre-legislation, 360 post-legislation). Multilevel logistic regression was used to examine changes in observed age-appropriate and correct use of car restraints. Age-appropriate car restraint use was higher post-legislation than pre-legislation. After controlling for child's age, parental income, language spoken at home and adjusting for clustering, the odds of children being appropriately restrained post-legislation were 2.3 times higher than in the pre-legislation sample, and the odds of them being correctly restrained were 1.6 times greater. Results indicate an improvement in car restraint practices among children aged 2-5 in low socioeconomic areas after introduction of child restraint laws. Implications : Despite improvements observed with enhanced legislation, further efforts are required to increase optimal child car restraint use. © 2013 The Authors.

In 2014, persons aged 13-29 years represented 23% of the U.S. population, yet accounted for 40% of diagnoses of human immunodeficiency virus (HIV) infection during the same year (1). During 2010-2014, the rates of diagnosis of HIV infection decreased among persons aged 15-19 years, were stable among persons aged 20-24 years, and increased among persons aged 25-29 years (1). However, these 5-year age groups encompass multiple developmental stages and potentially mask trends associated with the rapid psychosocial changes during adolescence through young adulthood. To better understand HIV infection among adolescents aged 13-17 years and young adults aged 18-29 years in the United States and identify ideal ages to target primary HIV prevention efforts, CDC analyzed data from the National HIV Surveillance System (NHSS)* using narrow age groups. During 2010-2014, rates of diagnosis of HIV infection per 100,000 population varied substantially among persons aged 13-15 years (0.7), 16-17 years (4.5), 18-19 years (16.5), and 20-21 years (28.6), and were higher, but less variable, among persons aged 22-23 years (34.0), 24-25 years (33.8), 26-27 years (31.3), and 28-29 years (28.7). In light of the remarkable increase in rates between ages 16-17, 18-19, and 20-21 years, and a recent study revealing that infection precedes diagnosis for young persons by an average of 2.7 years (2), these findings demonstrate the importance of targeting primary prevention efforts to persons aged <18 years and continuing through the period of elevated risk in their mid-twenties.

Eating disorders pose risks to health and wellbeing in young adolescents, but prospective studies of risk factors are scarce and this has impeded prevention efforts. This longitudinal study aimed to examine risk factors for eating disorder symptoms in a population-based birth cohort of young adolescents at 12 years. Participants from the Gateshead Millennium Study birth cohort (n = 516; 262 girls and 254 boys) completed self-report questionnaire measures of eating disorder symptoms and putative risk factors at age 7 years, 9 years and 12 years, including dietary restraint, depressive symptoms and body dissatisfaction. Body mass index (BMI) was also measured at each age. Within-time correlates of eating disorder symptoms at 12 years of age were greater body dissatisfaction for both sexes and, for girls only, higher depressive symptoms. For both sexes, higher eating disorder symptoms at 9 years old significantly predicted higher eating disorder symptoms at 12 years old. Dietary restraint at 7 years old predicted boys' eating disorder symptoms at age 12, but not girls'. Factors that did not predict eating disorder symptoms at 12 years of age were BMI (any age), girls' dietary restraint at 7 years and body dissatisfaction at 7 and 9 years of age for both sexes. In this population-based study, different patterns of predictors and correlates of eating disorder symptoms were found for girls and boys. Body dissatisfaction, a purported risk factor for eating disorder symptoms in young adolescents, developed concurrently with eating disorder symptoms rather than preceding them. However, restraint at age 7 and eating disorder symptoms at age 9 years did predict 12-year eating disorder symptoms. Overall, our findings suggest that efforts to prevent disordered eating might beneficially focus on preadolescent populations. Copyright © 2016 The Authors. Published by Elsevier Ltd..

Bullying and being exposed to bullying among children is prevalent, especially among children with psychiatric symptoms, and constitutes a major concern worldwide. Whether childhood bullying or exposure to bullying in the absence of childhood psychiatric symptoms is associated with psychiatric outcomes in adulthood remains unclear. To study the associations between bullying behavior at 8 years of age and adult psychiatric outcomes by 29 years of age. Nationwide birth cohort study of 5034 Finnish children with complete information about childhood bullying behavior was followed up from 8 to 29 years of age. Follow-up was completed on December 31, 2009, and data were analyzed from January 15, 2013, to February 15, 2015. Information about bullying, exposure to bullying, and psychiatric symptoms were obtained from parents, teachers, and child self-reports when children were 8 years of age. Use of specialized services for psychiatric disorders from 16 to 29 years of age was obtained from a nationwide hospital register, including outpatient and inpatient treatment. Among the 5034 study participants, 4540 (90.2%) did not engage in bullying behavior; of these, 520 (11.5%) had received a psychiatric diagnosis at follow-up; 33 of 166 (19.9%) who engaged in frequent bullying, 58 of 251 (23.1%) frequently exposed to bullying, and 24 of 77 (31.2%) who both frequently engaged in and were frequently exposed to bullying had received psychiatric diagnoses at follow-up. When analyses were adjusted by sex, family factors, and child psychiatric symptoms at 8 years of age, we found independent associations of treatment of any psychiatric disorder with frequent exposure to bullying (hazard ratio [HR], 1.9; 95% CI, 1.4-2.5) and being a bully and exposed to bullying (HR, 2.1; 95% CI, 1.3-3.4). Exposure to bullying was specifically associated with depression (HR, 1.9; 95% CI, 1.2-2.9). Bullying was associated with psychiatric outcomes only in the presence of psychiatric problems at 8 years

Presbyopia is an age-related loss of lens accommodation resulting in difficulty in performing near task with attendant effect on the quality of life. The objective of the study was to determine the prevalence of presbyopia and presbyopic spectacle correction coverage among public school teachers in Ifo township, with a view to providing a baseline information that could be useful for advocacy and planning appropriate intervention. The study was a descriptive, cross-sectional study. Six hundred public school teachers aged 30 years and above were examined in 25 clusters using a multistage random sampling technique with probability proportional to size. Questionnaire was used to obtain information on demographic data, sources of spectacle and barriers to spectacle use. All participants underwent a standardised protocol including visual acuity assessment (distance and near acuity), anterior and posterior segment examinations and refraction. Six hundred teachers were examined with an age range of 30-61 years. The mean age was 44.7 ± 7.5 years and the male to female ratio was 1:2.2. The prevalence of presbyopia was 81.3% and 38.5% of the presbyopic teachers did not have presbyopic correction. However, the average age of onset of presbyopia was earlier in females 33 years compared to 36 years observed in males, although not statistically significant (P = 0.88). The presbyopic correction coverage was 61.5%. One hundred and eighty-six (62%) presbyopic teachers obtained their spectacle from opticians, and the main barriers to the use of near vision spectacle were lack of awareness (23.7%) and cost (13.7%). This study demonstrated a high prevalence of presbyopia among public school teachers in Ifo town, South-West Nigeria, but less presbyopic spectacle correction coverage.

Little is known about the influence of advertising on very young children. We, therefore, measured product logo recognition by subjects aged 3 to 6 years. Children were instructed to match logos with one of 12 products pictured on a game board. Twenty-two logos were tested, including those representing children's products, adult products, and those for two popular cigarette brands (Camel and Marlboro). Preschools in Augusta and Atlanta, Ga. A convenience sample of 229 children attending preschool. The children demonstrated high rates of logo recognition. When analyzed by product category, the level of recognition of cigarette logos was intermediate between children's and adult products. The recognition rates of The Disney Channel logo and Old Joe (the cartoon character promoting Camel cigarettes) were highest in their respective product categories. Recognition rates increased with age. Approximately 30% of 3-year-old children correctly matched Old Joe with a picture of a cigarette compared with 91.3% of 6-year-old children. Very young children see, understand, and remember advertising. Given the serious health consequences of smoking, the exposure of children to environmental tobacco advertising may represent an important health risk and should be studied further.

This report of health care spending in fiscal year 1977 reveals that of the $142.6 billion spent by the Nation for personal health care in fiscal year 1977, 29 percent was spent for those aged 65 or older, 59 percent for those aged 19-64, and 13 percent for those below age 19. The average health bill reached $1,745 for the aged, $661 for the intermediate age group, and $253 for the young. Public funds financed 67 percent of the health expenses of the aged, with Medicare and Medicaid together accounting for 61 percent. More than two-thirds of the health expenses of the young and 71 percent of the expenses of those aged 19-64 were paid by private sources. Third-party payments met 68 percent of the health expenditures of all those under age 65.

Anaemia is one of the significant public health problems among children in the world. Understanding risk factors of anaemia provides more insight to the nature and types of policies that can be put up to fight anaemia. We estimated the prevalence and risk factors of anaemia in a population-based, cross-sectional survey. Blood samples from 11,711 children aged between 6 months and 14 years were collected using a single-use, spring-loaded, sterile lancet to make a finger prick. Anaemia was measured based on haemoglobin concentration level. The generalized linear model framework was used to analyse the data, in which the response variable was either a child was anemic or not anemic. The overall prevalence of anaemia among the children in Kenya was estimated to be 28.8%. Across each band of age within which the definition of anaemia remained constant (0–4, 5–11, and 12–14 years old), the prevalence of anaemia declined with each year of age. [corrected]. The risk of anaemia was significantly higher in male than female children. Mothers with secondary and above education had a protective effect on the risk of anaemia on their children. Malaria diagnosis status of a child was positively associated with risk anaemia. Controlling co-morbidity of malaria and improving maternal knowledge are potential options for reducing the burden of anaemia.

To study the effect and long-term sustainability of part-time occlusion therapy for anisometropic amblyopia after 8 years of age. A total of 41 anisometropic amblyopes aged > or =8 years were analysed. In six patients, best-corrected visual acuity (BCVA) of amblyopic eye improved more than two lines within 2 weeks of full-time spectacle wear. The remaining patients were assigned to perform part-time patching during out-of-school hours. Long-term results were assessed in patients who were observed over 1 year after the end of the treatment. Among 35 patients, four dropped out, refusing further treatment, and one changed to atropine penalisation. The part-time patching schedule was completed in 30 patients. 90% of patients (27/30) complied well. Mean BCVA in the amblyopic eye improved significantly (p<0.001), and 96.7% of patients (29/30) achieved the final BCVA of 0.1 logMAR or better. In long-term results, 87% preserved the BCVA of 0.1 logMAR or better. None of four dropouts achieved the BCVA of 0.1 logMAR or better in long-term results even on the continuous spectacle wear. The part-time occlusion treatment in school-aged amblyopes, which had been carried out after school hours, was successful and the effect was sustained in most cases.

To determine the outcome of part-time occlusion therapy in children with anisometropic amblyopia detected after they were 8 years of age. We analyzed 29 eyes with anisometropic amblyopia in children 8 years of age and older. The mean age was 8.79 +/- 0.98 (range 8-12) years old. The subjects whose best-corrected visual acuity (BCVA) did not improve by two lines or better within 2 weeks of wearing glasses full-time were prescribed occlusion therapy for 6 hours a day outside of school hours, along with the instruction to wear glasses full-time. Subjects who complied with occlusion for more than 3 hours a day were considered to comply well. The major component of the anisometropia was hyperopia in 51.7% of the subjects, and hyperopia plus astigmatism was found in 24.1%. The mean pretreatment BCVA score was 0.51 0.23 (LogMAR). Compliance was 89.66%. The mean posttreatment BCVA was 0.03 +/- 0.01 (LogMAR), and the success rate, based on a posttreatment BCVA of 0.1 (LogMAR) and better, was 96.43%. It took an average of 4.79 +/- 3.35 months to reach the desired posttreatment BCVA. The mean posttreatment stereopsis was 79.78 +/- 37.61 seconds of arc. The recurrence rate was 8%. The visual improvement was related to the degree of compliance (p = 0.000). The time taken to reach the posttreatment BCVA was shorter in subjects with a better pretreatment BCVA (p = 0.019), but it did not relate to the compliance (p = 0.366). The most common component of anisometropia detected after 8 years of age was hyperopia. The part-time occlusion therapy, which had been carried out after school hours, was successful in most cases.

To evaluate the basic principles of surgical correction of concealed penis. From Jan. 1999 to Dec. 2002, 63 cases of concealed penis, aged from 1 year and 6 months to 19 years with a mean age of 7 years and 2 months, were corrected with two different approaches: 37 cases of group A with obesity were corrected by anchoring micrus tissue onto the pubis at the base of the penis, and 26 cases of group B by fixing the subcutateous tissues at both sides of the penile shaft to the deep tunica albuginea at the penile root. Then prepuce plasty was carried out. Six-month postoperative follow-up found adequate exposure of the penis in all of group A, prepuce oedema in 7 cases, abdomen fat liquidization in 3 cases, unsatisfactory recovery of incision hollow in 3 cases and patchy numbness of the glans in 1 case. The 25 cases of group B had satisfactory exposure of the penis, with no obvious prepuce oedema, 1 case with retraction of the penis 7 days after operation. Various surgical procedures could be adopted for concealed penis, and the key to the satisfactory appearance is the restoration of penile tunicae and the fixation at the base of the penis. Further study is needed to determine the natural history of these disorders as well as which conditions and what age will benefit most from surgical intervention.

The primary aim of this study was to investigate the accuracy of the Alberta Infant Motor Scale (AIMS) and Neuro-Sensory Motor Developmental Assessment (NSMDA) over the first year of life for predicting motor impairment at 4 years in preterm children. The secondary aims were to assess the predictive value of serial assessments over the first year and when using a combination of these two assessment tools in follow-up. Children born <30 weeks' gestation were prospectively recruited and assessed at 4, 8 and 12 months' corrected age using the AIMS and NSMDA. At 4 years' corrected age children were assessed for cerebral palsy (CP) and motor impairment using the Movement Assessment Battery for Children 2nd-edition (MABC-2). We calculated accuracy of the AIMS and NSMDA for predicting CP and MABC-2 scores ≤15th (at-risk of motor difficulty) and ≤5th centile (significant motor difficulty) for each test (AIMS and NSMDA) at 4, 8 and 12 months, for delay on one, two or all three of the time points over the first year, and finally for delay on both tests at each time point. Accuracy for predicting motor impairment was good for each test at each age, although false positives were common. Motor impairment on the MABC-2 (scores ≤5th and ≤15th) was most accurately predicted by the AIMS at 4 months, whereas CP was most accurately predicted by the NSMDA at 12 months. In regards to serial assessments, the likelihood ratio for motor impairment increased with the number of delayed assessments. When combining both the NSMDA and AIMS the best accuracy was achieved at 4 months, although results were similar at 8 and 12 months. Motor development during the first year of life in preterm infants assessed with the AIMS and NSMDA is predictive of later motor impairment at preschool age. However, false positives are common and therefore it is beneficial to follow-up children at high risk of motor impairment at more than one time point, or to use a combination of assessment tools.

To explore the method and experience in correction of pectus carinatum with minimally invasive procedure. Between June 2010 and January 2014, 30 patients with pectus carinatum were corrected by minimally invasive procedure. There were 21 boys and 9 girls whose average age was 13 years and 2 months (range, from 8 years and 10 months to 18 years and 9 months), including 24 cases of first operation, 2 recurrence after traditional pectus carinatum correction, and 4 cases secondary to median thoracotomy. Thirty patients had symmetric and asymmetric mild pectus carinatum. The operation was performed successfully in all patients, and no severe complication occurred. The operation time was 42-95 minutes (mean, 70 minutes). The bleeding volume during operation was 4-30 mL (mean, 10 mL). The time from operation to discharge was 6-10 days (mean, 7 days). The average time of follow-up was 25 months (range, 9-54 months). All surgical wound healed primarily with no infection. The X-ray films showed slight pneumothorax in 7 cases, and it was absorbed after 1 month without treatment. Loosening of internal fixation was found in 1 patient because of trauma at 6 months, and operation was performed again. The bar was removed at 2 years in 21 patients. The patients had good thoracic contour and normal activity. Minimally invasive procedure for correction of pectus carinatum is safe and will get satisfactory effect in maintaining thoracic contour. It has also less trauma and shorter operation time.

To explore the association between alcohol consumption at age 11-12 years and traumatic dental injuries (TDI) at age 15-16 years. Data of 635 adolescents who participated in phases I and III of the Research with East London Adolescents Community Health Survey (RELACHS), a longitudinal school-based survey of a representative sample of adolescents from East London, were used for this study. Information on socio-demographic characteristics and alcohol consumption was obtained from questionnaires in phase I when adolescents were 11-12 years of age. Data on TDI and clinical characteristics (incisor overjet and lip coverage) were taken from clinical examination in phase III when adolescents were 15-16 years of age. The association between (lifetime and last month) alcohol consumption and TDI was assessed in crude and adjusted logistic regression models. Overall, 14.5% of adolescents had ever consumed alcohol and 3.5% had consumed alcohol the month before the baseline survey, whereas 17% of adolescents had experienced TDI by age 15-16 years. No significant association of alcohol consumption with TDI was seen in these adolescents for either lifetime (adjusted odds ratio [OR]: 0.87; 95% confidence interval [CI]: 0.45-1.67) or last month consumption of alcohol (adjusted OR: 0.86; 95% CI: 0.28-2.69). This study did not support the association between alcohol use and TDI in adolescents. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We investigated the effects of refractive correction and refractive defocus on the assessment of sensory ocular dominance. In 25 healthy subjects (4 males and 21 females) aged between 20 and 31 years, a quantitative measurement of sensory ocular dominance was performed with refractive correction and the addition of a positive lens on the dominant eye. Sensory ocular dominance was measured with a chart using binocular rivalry targets. The reversal point changed after the addition of a +1.00 D lens on the dominant eye in all subjects. However, sighting ocular dominance and stereopsis did not change after the addition of a positive lens on the dominant eye ( P > 0:05, Wilcoxon test). These results suggest that refractive correction affects sensory ocular dominance, indicating the possible development of a new type of occlusion for amblyopia in the future.

Understanding early-life risk factors for childhood death in cystic fibrosis (CF) is important for clinical care, including the identification of effective interventions. Data from the Epidemiologic Study of Cystic Fibrosis (ESCF) collected 1994-2005 were linked with the Cystic Fibrosis Foundation Patient Registry (CFFPR) demographic and mortality data from 2013. Inclusion criteria were ≥1 visit annually at age 3-5 years and ≥1 FEV 1 measurement at age 6-8 years. Demographic data, nutritional parameters, pulmonary signs and symptoms, microbiology, and FEV 1 were evaluated as risk factors for death before age 18 years. Multivariable Cox proportional hazards regression was used to model the simultaneous effects of risk factors associated with death before age 18 years. Among 5365 patients enrolled in ESCF who met inclusion criteria, 3880 (72%) were linked to the CFFPR. Among these, 191 (5.7%) died before age 18 years; median age at death was 13.4 ± 3.1 years. Multivariable regression showed clubbing, crackles, female sex, unknown CFTR genotype, minority race or ethnicity, Medicaid insurance (a proxy of low socioeconomic status), Pseudomonas aeruginosa on 2 or more cultures, and weight-for-age <50th percentile were significant risk factors for death regardless of inclusion of FEV 1 at age 6-8 years in the model. We identified multiple risk factors for childhood death of patients with CF, all of which remained important after incorporating FEV 1 at age 6-8 years. Among the factors identified were the presence of clubbing or crackles at age 3-5 years, signs which are not routinely collected in registries. © 2017 Wiley Periodicals, Inc.

Canine pulp ratios in estimating pensionable age in subjects with questionable documents of identification.

One of the most interesting reasons for needing to estimate age in adult subjects is to ascertain the age of a person of questionable pensionable age. This problem is becoming increasingly important in Europe, owing to the high number of immigrants without valid birth certificates. The aim of this paper is to evaluate the application of the apposition of secondary dentine of canines by the method of Cameriere et al. [10], in order to estimate the pensionable age of subjects without proper birth certificates. Periapical X-rays of 180 canines from 90 subjects aged between 50 and 79, 46 men and 44 women, were analysed. Estimated ages were used to test the medico-legal question as to whether an individual was older or younger than 65 years of age. In subjects under 65, age was correctly evaluated in 91% and 89% of individuals using maxillary and mandibular canines, respectively. In subjects over 65, of pensionable age, estimates were correct in 85% and 88% of cases, respectively. The proportion of individuals with correct classifications was 89% for both maxillary and mandibular canines taken together. In only four subjects, the results of maxillary and mandibular canines were discordant; in the other 86 subjects, the test of maxillary and mandibular canines yielded concordant results. Among the latter, the proportion of individuals who were really aged 65 years or older, and who were correctly estimated as such, was 94%, and the proportion of individuals younger than 65 years of age who were correctly estimated as such was 96%.

The majority of tobacco use emerges in individuals before they reach 21 years of age, and many adult distributors of tobacco to youths are young adults aged between 18 and 20 years. Raising the tobacco sales minimum age to 21 years across the United States would decrease tobacco retailer and industry sales by approximately 2% but could contribute to a substantial reduction in the prevalence of youths' tobacco use and dependency by limiting access.

To report the prevalence of myopia and high myopia in children <6 years of age born preterm with birth weights <1251 g who developed high-risk prethreshold retinopathy of prematurity and who participated in the Early Treatment for Retinopathy of Prematurity trial. Surviving children from the cohort of 401 participants who had developed high-risk prethreshold ROP in one or both eyes underwent cycloplegic retinoscopy at 6 and 9 months corrected age and yearly between 2 and 6 years postnatal age. Eyes were randomized to receive treatment at high-risk prethreshold ROP or conventional management with treatment only if threshold ROP developed. Myopia (spherical equivalent ≥0.25 D) or high myopia (≥5.00 D) in eyes at 4-, 5-, and 6-year examinations was reported. At ages 4, 5, and 6 years, there was no difference in the percentage of eyes with myopia (range, 64.8%-69.9%) and eyes with high myopia (range, 35.3%-39.4%) between earlier treated and conventionally managed eyes. Approximately two-thirds of eyes with high-risk prethreshold ROP during the neonatal period are likely to be myopic into the preschool and early school years. In addition, the increase in the proportion of eyes with high myopia that had been observed in both earlier-treated and conventionally managed eyes between ages 6 months and 3 years does not continue between ages 3 and 6 years.

To determine the near vision spectacle coverage and barriers to obtaining near vision correction among adults aged 35 years and older in the Cape Coast Metropolis of Ghana. A population-based cross-sectional study design was adopted and 500 out of 576 participants aged 35 years and older were examined from 12 randomly selected clusters in Cape Coast, Ghana. All participants underwent a comprehensive eye examination which included: distance and near visual acuities measurements and external and internal ocular health assessments. Distance and near refractions were performed using subjective refraction technique. Information on participants' demographics, near vision correction status, near visual needs and barriers to acquiring near vision correction were obtained through a questionnaire administered as part of the study. The mean age of participants was 52.3±10.3 years of whom 280 (56%) were females and 220 (44%) were males. The near vision spectacle coverage was 25%, 33% "met need" for near vision correction in the presbyopic population, and 64% unmet need in the entire study population. After controlling for other variables, age (5 th and 6 th decades) and educational level were associated with "met need" for near vision correction (OR=2.7 (1.55-4.68), p =0.00, and OR=2.36 (1.18-4.72), p=0.02 respectively). Among those who needed but did not have near vision correction, 64 (26%) did not feel the need for correction, 55 (22%) stated that they were unaware of available interventions, and 53 (21%) found the cost of near vision correction prohibitive. There was a low near vision spectacle coverage in this population which suggests the need for strategies on health education and promotion to address the lack of awareness of spectacle need and cost of services.

To analyze the changes in corneal astigmatism as a function of age and develop a novel model to estimate corneal astigmatic change according to age. This was a cross-sectional study of right eyes of 3,769 individuals. Total corneal astigmatism, keratometric astigmatism, anterior corneal astigmatism, and posterior corneal astigmatism were measured by a Scheimpflug tomographer. Smoothing fitting curves of polar values of corneal astigmatism as a function of age were drawn and average changes in corneal astigmatism at different ages were calculated. Two turning points of age on total corneal astigmatism were 36 and 69 years. The average change of total corneal astigmatism toward against-the-rule astigmatism was 0.13 diopters (D)/10 years from 18 to 35 years, 0.45 D/10 years from 36 to 68 years, and decreased after 69 years, mainly caused by anterior corneal astigmatism. The mean magnitude of posterior corneal astigmatism was -0.33 D and exceeded 0.50 D in 14.27% of eyes. The vectorial difference between total corneal astigmatism and keratometric astigmatism was correlated with posterior corneal astigmatism, polar value of anterior corneal astigmatism, age, and corneal higher order aberrations (r = 0.636; standard partial regression coefficients were 0.479, -0.466, 0.282, and 0.196, respectively; all P < .001). Based on the non-linear model to estimate corneal astigmatic change with age, a formula was developed to calculate recommended correction of astigmatism according to age and astigmatic type. The rate of change of total corneal astigmatism showed a non-linear trend toward against-the-rule astigmatism, which was low at young and old age, high at middle age, and should be taken into account when performing surgery to correct astigmatism.

In this multicentre retrospective data analysis from electronic medical record, consecutive treatment-naive patients with nAMD treated with aflibercept with at least 2 years follow-up were stratified into those aged < 90 years (Group I) and an older cohort aged 90 and over (Group II). We compared the visual acuity (EDTRS letters) outcomes at 4 weekly intervals between the two groups over a 2-year period. The mean visual acuity of Group I at presentation was 56.3 ETDRS letters versus 52.8 letters in Group II. Maximal visual acuity was achieved in both the groups by 6 months after initiating treatment (4.7 vs. 4.0 letters gain). By 2 years, the mean visual acuity of the older cohort fell marginally below their baseline visual acuity (0.8 letter loss), while Group I presented +2.1 letters gain. The number of injections given and the retention rate of the older cohort were no different to the rest of the patients. Very old patients with nAMD benefited from aflibercept, but not to the same degree as the younger patients. The study showed that, on an average, the very elderly patients were able to adhere to the intensive anti-VEGF treatment regimens.

Patients with idiopathic scoliosis, although otherwise healthy, often have significant concerns about their self-image and appearance. In a group of juveniles and adolescents, this can impact adjustment in school, functioning in peer groups, and general sense of well-being. There are limited data to help physicians reliably and precisely identify those who are at higher risk of poor emotional adjustment even after spine deformity correction. The purpose of this study was to determine the predictors of emotional maladjustment in juvenile and adolescent patients after surgical correction of idiopathic scoliosis. A total of 233 juveniles, mean age 11.26 ± 1.02 (range, 8 to 12) years and 909 adolescents, mean age 14.91 ± 1.61 (range, 13 to 21) years, who underwent surgical correction for idiopathic scoliosis and who were participating in a prospective longitudinal multicenter database, were enrolled in the study. Participants completed the Scoliosis Research Society-22 (SRS-22) questionnaire before surgery and 2 years postoperatively. Radiographs were used to measure Cobb angle and surface measurements were used to determine decompensation and trunk shift. Adolescents reported poorer mental health preoperatively (P<0.05) and 2 years postoperatively (P<0.001) than juveniles; however, both groups reported improved mental health (P<0.001) and self-image (P<0.01) postoperatively. Mental health 2 years postoperatively was predicted by preoperative self-image (P<0.05), mental health (P<0.001), and main thoracic Cobb angle (P<0.05) in the juvenile group. Within the adolescent group, mental health 2 years postoperatively was predicted by preoperative mental health (P<0.001); self-image 2 years postoperatively was predicted by preoperative mental health (P<0.01) and self-image (P<0.001). Self-image and mental health are significantly improved after spine deformity correction in juveniles and adolescents with idiopathic scoliosis. However, consistent with normative development

Numerous studies have identified the effects of prematurity on the neonate's physical health, however few studies have explored the effects of prematurity on both the physical and mental health of the child as they develop. Secondary analysis of data from the Millennium Cohort Study, a longitudinal study of infants (n = 18 818, born 2000-2002 in the United Kingdom) was performed. Effects of gestational age at birth on health outcomes at 5 years were measured using parental rating of their children's general health and severity of behavior problems. The association between parent's general health ratings and behavior problem ratings was low: 86% of those reporting serious behavior problems (5% of the sample, n = 764) rated their child as being in excellent, very good, or good health. Still, a gradient of increasing risk of poorer outcome with decreasing gestational age was observed for a composite health measure (poor/fair health and/or serious behavior problems), suggesting an association with prematurity for this composite assessment of health status. The greatest contribution to the childhood composite health measure at 5 years was for children born at 32-36 weeks gestation: population attributable fractions for having poor outcomes was 3.4% (Bonferroni-adjusted 95% confidence interval 1.1%-6.2%), compared to 1% (0.2-2.3) for birth at less than 32 weeks. Results suggest that preterm children, by school entry, are not only at high risk of physical health problems, but also of behavioral health problems. The recognition of, and response to comprehensive health and well-being outcomes related to prematurity are important in order to correctly plan and deliver adequate paediatric health services and policies.

Sugar-sweetened beverages (SSBs) have been associated with obesity in children and adults; however, associations between beverage patterns and obesity are not understood. Our aim was to describe beverage patterns during adolescence and associations between adolescent beverage patterns and anthropometric measures at age 17 years. We conducted a cross-sectional analyses of longitudinally collected data. Data from participants in the longitudinal Iowa Fluoride Study having at least one beverage questionnaire completed between ages 13.0 and 14.0 years, having a second questionnaire completed between 16.0 and 17.0 years, and attending clinic examination for weight and height measurements at age 17 years (n=369) were included. Beverages were collapsed into four categories (ie, 100% juice, milk, water and other sugar-free beverages, and SSBs) for the purpose of clustering. Five beverage clusters were identified from standardized age 13 to 17 years mean daily beverage intakes and named by the authors for the dominant beverage: juice, milk, water/sugar-free beverages, neutral, and SSB. Weight, height, and body mass index (BMI; calculated as kg/m 2 ) at age 17 years were analyzed. We used Ward's method for clustering of beverage variables, one-way analysis of variance and χ 2 tests for bivariable associations, and γ-regression for associations of weight or BMI (outcomes) with beverage clusters and demographic variables. Linear regression was used for associations of height (outcome) with beverage clusters and demographic variables. Participants with family incomes <$60,000 trended shorter (1.5±0.8 cm; P=0.070) and were heavier (2.0±0.7 BMI units; P=0.002) than participants with family incomes ≥$60,000/year. Adjusted mean weight, height, and BMI estimates differed by beverage cluster membership. For example, on average, male and female members of the neutral cluster were 4.5 cm (P=0.010) and 4.2 cm (P=0.034) shorter, respectively, than members of the milk cluster. For

Background: We present the magnitude and determinants of age-related macular degeneration (ARMD) among the 50 year and older population that visited our hospital. Materials and Methods: This was a cohort of eye patients with ARMD, seen from 2006 to 2009. Optometrist noted the best-corrected vision. Ophthalmologists examined eyes using a slit-lamp bio-microscope. The ARMD was confirmed by fluoresceine angiography and optical coherent tomography. The age, sex, history of smoking, sun exposure, family history of ARMD, diet, body mass index (BMI), hypertension, and diabetes were associated with ARMD. Result: Of the 19,140 persons of ≥ 50 years of age-attending eye clinic in our hospital, 302 persons had ARMD in at least one eye. The proportion of overall ARMD was 1.38% (95% CI 1.21--1.55). The proportion of age-related maculopathy (ARM) and late ARMD was 1.14% (95% CI 0.99--1.29) and 0.24% (95% CI 0.21–0.24) respectively. ARM was unilateral and bilateral in 64 (29.2%) and 155 (70.8%) persons respectively. Dry ARMD was found in 47.8%. On regression analysis, old age (OR = 1.05), male (OR = 0.54), and history of smoking (OR = 2.32) were significant risk factors of ARMD. A total of 4.2% of persons with ARMD were blind (vision <3/60). Only 43% of persons with ARMD had J6 grade of the best-corrected near vision. Conclusion: ARMD does not seem to be of public health magnitude in the study area. Early stages of ARMD were common among patients. ge, being male, and history of smoking were significant risk factors for ARMD. PMID:23571245

To compare cortical hemodynamic responses to known and unknown facial stimuli between infants born extremely preterm and term-born infants, and to correlate the responses of the extremely preterm-born infants to regional cortical volumes at term-equivalent age. We compared 27 infants born extremely preterm (<28 gestational weeks) with 26 term-born infants. Corrected age and chronological age at testing were between 6 and 10 months, respectively. Both groups were exposed to a gray background, their mother's face, and an unknown face. Cerebral regional concentrations of oxygenated and deoxygenated hemoglobin were measured with near-infrared spectroscopy. In the preterm group, we also performed structural brain magnetic resonance imaging and correlated regional cortical volumes to hemodynamic responses. The preterm-born infants demonstrated different cortical face recognition processes than the term-born infants. They had a significantly smaller hemodynamic response in the right frontotemporal areas while watching their mother's face (0.13 μmol/L vs 0.63 μmol/L; P < .001). We also found a negative correlation between the magnitude of the oxygenated hemoglobin increase in the right frontotemporal cortex and regional gray matter volume in the left fusiform gyrus and amygdala (voxels, 25; r = 0.86; P < .005). At 6-10 months corrected age, the preterm-born infants demonstrated a different pattern in the maturation of their cortical face recognition process compared with term-born infants.

Exercise intolerance may be reported by parents of young children with respiratory diseases. There is, however, a lack of standardized exercise protocols which allow verification of these reports especially in younger children. Consequently the aims of this pilot study were to develop a standardized treadmill walking test for children aged 4-10 years demanding low sensorimotor skills and achieving high physical exhaustion. In a prospective experimental cross sectional pilot study, 33 healthy Caucasian children were separated into three groups: G1 (4-6 years, n = 10), G2 (7-8 years, n = 12), and G3 (9-10 years, n = 11). Children performed the treadmill walking test with increasing exercise levels up to peak condition with maximal exhaustion. Gas exchange, heart rate, and lactate were measured during the test, spirometry before and after. Parameters were statistically calculated at all exercise levels as well as at 2 and 4 mmol/L lactate level for group differences (Kruskal-Wallis H-test, alpha = 0.05; post hoc: Mann-Whitney U-test with Bonferroni correction alpha = 0.05/n) and test-retest differences (Wilcoxon-rank-sum test) with SPSS. The treadmill walking test could be demonstrated to be feasible with a good repeatability within groups for most of the parameters. All children achieved a high exhaustion level. At peak level under exhaustion condition only the absolute VO2 and VCO2 differed significantly between age groups. In conclusion this newly designed treadmill walking test indicates a good feasibility, safety, and repeatability. It suggests the potential usefulness of exercise capacity monitoring for children aged from early 4 to 10 years. Various applications and test modifications will be investigated in further studies.

Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P < .001). There was no significant difference for all patient-reported outcome (PRO) scores at final follow-up between both groups. When we compared the change in PRO scores (�

This study created and tested a database of adult, age-specific MRI brain and head templates. The participants included healthy adults from 20 through 89 years of age. The templates were done in five-year, 10-year, and multi-year intervals from 20 through 89 years, and consist of average T1W for the head and brain, and segmenting priors for gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF). It was found that age-appropriate templates provided less biased tissue classification estimates than age-inappropriate reference data and reference data based on young adult templates. This database is available for use by other investigators and clinicians for their MRI studies, as well as other types of neuroimaging and electrophysiological research.1 PMID:25904864

Aim The primary aim of this study was to investigate the accuracy of the Alberta Infant Motor Scale (AIMS) and Neuro-Sensory Motor Developmental Assessment (NSMDA) over the first year of life for predicting motor impairment at 4 years in preterm children. The secondary aims were to assess the predictive value of serial assessments over the first year and when using a combination of these two assessment tools in follow-up. Method Children born <30 weeks’ gestation were prospectively recruited and assessed at 4, 8 and 12 months’ corrected age using the AIMS and NSMDA. At 4 years’ corrected age children were assessed for cerebral palsy (CP) and motor impairment using the Movement Assessment Battery for Children 2nd-edition (MABC-2). We calculated accuracy of the AIMS and NSMDA for predicting CP and MABC-2 scores ≤15th (at-risk of motor difficulty) and ≤5th centile (significant motor difficulty) for each test (AIMS and NSMDA) at 4, 8 and 12 months, for delay on one, two or all three of the time points over the first year, and finally for delay on both tests at each time point. Results Accuracy for predicting motor impairment was good for each test at each age, although false positives were common. Motor impairment on the MABC-2 (scores ≤5th and ≤15th) was most accurately predicted by the AIMS at 4 months, whereas CP was most accurately predicted by the NSMDA at 12 months. In regards to serial assessments, the likelihood ratio for motor impairment increased with the number of delayed assessments. When combining both the NSMDA and AIMS the best accuracy was achieved at 4 months, although results were similar at 8 and 12 months. Interpretation Motor development during the first year of life in preterm infants assessed with the AIMS and NSMDA is predictive of later motor impairment at preschool age. However, false positives are common and therefore it is beneficial to follow-up children at high risk of motor impairment at more than one time point, or to use a

Applicability of Age-Based Hunting Regulations for African Leopards

In species in which juvenile survival depends strongly on male tenure, excessive trophy hunting can artificially elevate male turnover and increase infanticide, potentially to unsustainable levels. Simulation models show that the likelihood of safe harvests can be improved by restricting offtakes to males old enough to have reared their first cohort of offspring to independence; in the case of African leopards, males were ≥7 years old. Here, we explore the applicability of an age-based approach for regulating trophy hunting of leopards. We conducted a structured survey comprising photographs of known-age leopards to assess the ability of wildlife practitioners to sex and age leopards. We also evaluated the utility of four phenotypic traits for use by trophy hunters to age male leopards in the field. Our logistic regression models showed that male leopard age affected the likelihood of survey respondents identifying the correct sex; notably, males <2 years were typically misidentified as females, while mature males (≥4 years) were sexed correctly. Mature male leopards were also more likely to be aged correctly, as were portrait photographs. Aging proficiency was also influenced by the profession of respondents, with hunters recording the lowest scores. A discriminant model including dewlap size, the condition of the ears, and the extent of facial scarring accurately discriminated among male leopard age classes. Model classification rates were considerably higher than the respective scores attained by survey respondents, implying that the aging ability of hunters could theoretically improve with appropriate training. Dewlap size was a particularly reliable indicator of males ≥7 years and a review of online trophy galleries suggested its wider utility as an aging criterion. Our study demonstrated that an age-based hunting approach is practically applicable for leopards. However, implementation would require major reform within the regulatory framework and the

To present progress toward Healthy People 2010 vaccination objectives for adolescents aged 13-15 years, and to determine how much catch-up and routine vaccination was administered at the recommended ages of 11-12 years. Data from the 1997-2003 National Health Interview Survey were evaluated. In the first analysis, vaccination coverage levels for adolescents aged 13-15 years were determined for each survey year. Main outcome measures include the percent of adolescents who had received the three-dose hepatitis B vaccine (Hep B) series, the two-dose measles/mumps/rubella vaccine (MMR) series, the tetanus and diphtheria toxoids (Td) booster, and one dose of varicella vaccine. In the second analysis, data from all survey years were combined and vaccination dates were analyzed to determine the percentage of adolescents who were missing any vaccines at ages 11-12 and received them at that age. Data for varicella vaccine were sufficient only for the first analysis. Among the approximately 15%-20% of respondents who reported vaccination history from records in the home and who were reporting on a 13-15-year-old, coverage with three doses of Hep B increased significantly during 1997-2001, from 15.2% to 55.0%. Coverage with MMR and Td fluctuated, with no significant increase; highs were 76.7% for MMR in 2003 and 36.2% for Td in 2002. Examination of vaccination dates for all surveyed adolescents showed that among 11-12-year-olds who needed catch-up vaccine, 0.6%-31.3% were brought up to date for Hep B and 22.1%-31.8% were brought up to date for MMR. For Td, 2.6%-15.4% of 11-12-year-olds who had not previously received Td received the vaccine. Vaccination coverage among adolescents aged 13-15 years was below the Healthy People 2010 goals of 90%, but generally increased over the survey years. However, the suboptimal delivery of needed vaccines during ages 11 and 12 is concerning in light of recent vaccine recommendations targeted at this age. Continuing to focus on strategies to

We wanted to evaluate the efficacy of Ponseti's technique in neglected clubfoot in children more than 7 years of age. The results of Ponseti's method were evaluated in 21 children (25 feet) with neglected club feet. Patients were evaluated using the Dimeglio scoring system. All patients underwent percutaneous tenotomy of the Achilles tendon. The mean age at the time of treatment was 8.9 years. The mean follow-up period was 4.7 years. The average Dimeglio score at the start of the treatment was 14.2 compared with an average score of 0.95 at the end of the treatment at 1-year follow-up. Eighteen feet (85.7%) had full correction. Recurrence was seen in six feet (24%). At 4-year follow-up, the average Dimeglio score for 19 feet was 0.18. We recommend that Ponseti's method should be the preferred initial treatment modality for neglected clubfeet.

To analyze early postoperative period in patients with diffuse pulmonary emphysema after palliative surgical correction of respiratory failure. The study included 196 patients who underwent bullectomy (n=111) and surgical reduction of pulmonary volume (n=85). Overall morbidity and mortality were 40.8% and 12.2% respectively. Among patients older than 60 years these values were significantly higher (58.0% and 22.6% respectively). It was shown that age over 60 years is associated with high risk of complications and mortality after excision of large and giant bulls. In patients <60 years morbidity is comparable after bullectomy and surgical reduction of pulmonary volume. Selection of patients for palliative surgical correction of respiratory failure is generally corresponded to that for lung transplantation. However, these methods should be considered complementary rather competing.

Current reported incidence rates for ovarian cancer may significantly underestimate the true rate because of the inclusion of women in the calculations who are not at risk for ovarian cancer due to prior benign salpingo-oophorectomy (SO). We have considered prior SO to more realistically estimate risk for ovarian cancer. Kentucky Health Claims Data, International Classification of Disease 9 (ICD-9) codes, Current Procedure Terminology (CPT) codes, and Kentucky Behavioral Risk Factor Surveillance System (BRFSS) Data were used to identify women who have undergone SO in Kentucky, and these women were removed from the at-risk pool in order to re-assess incidence rates to more accurately represent ovarian cancer risk. The protective effect of SO on the population was determined on an annual basis for ages 5–80+ using data from the years 2009–2013. The corrected age-adjusted rates of ovarian cancer that considered SO ranged from 33% to 67% higher than age-adjusted rates from the standard population. Correction of incidence rates for ovarian cancer by accounting for women with prior SO gives a better understanding of risk for this disease faced by women. The rates of ovarian cancer were substantially higher when SO was taken into consideration than estimates from the standard population. PMID:28368298

Pulmonary blood flow may affect lung development in adulthood. Early total correction of tetralogy of Fallot may affect development of final lung volumes. We evaluated the effect of age at total correction on lung volumes years after the operation. In a retrospective cohort study on patients with totally corrected tetralogy of Fallot (mean age, 13.40 years at the time of follow-up), forced vital capacity, slow vital capacity, forced expiratory volume in 1 s, and other parameters were measured 154.8 ± 46.25 months after the operation. Comparison were made of 3 groups: ≤2-, 2-8-, and >8-years old at the time of total correction surgery. Among 322 enrolled patients, the mean values of the follow-up spirometry results in ≤2-, 2-8-, >8-year-olds and the percentage of predicted values were respectively: vital capacity: 4.46 ± 0.57 L (107% ± 10.96%), 3.89 ± 0.58 L (91.10% ± 12.25%), 3.25 ± 0.48 L (82.35% ± 10.62%), p < 0.001; forced vital capacity: 4.28 ± 0.63 L (95.90% ± 18.77%), 3.76 ± 0.58 L (90.83% ± 12.52%), 3.14 ± 0.49 L (83.26% ± 11.71%), p < 0.001; forced expiratory volume in 1 s: 4.22 ± 0.63 L (104.84% ± 13.64%), 3.66 ± 0.58 L (90.61% ± 12.59%), 3.02 ± 0.48 L (84.31% ± 12%), p < 0.001. Early correction of defects or reestablishments of perfusion of tetralogy of Fallot before completion of lung development might improve final adulthood lung volumes and capacities. It is better to consider total correction for all tetralogy of Fallot patients below 2-years old, or at least below 8-years old, if it is technically possible.

Traffic crashes have high mortality and morbidity for young children. Though many specialized child restraint systems improve injury outcomes, no large-scale studies have investigated the cross-chest clip's role during a crash, despite concerns in some jurisdictions about the potential for neck contact injuries from the clips. This study aimed to investigate the relationship between cross-chest clip use and injury outcomes in children between 0 and 4 years of age. Child passengers between 0 and 4 years of age were selected from the NASS-CDS data sets (2003-2014). Multiple regression analysis was used to model injury outcomes while controlling for age, crash severity, crash direction, and restraint type. The primary outcomes were overall Abbreviated Injury Score (AIS) 2+ injury, and the presence of any neck injury. Across all children aged 0-4 years, correct chest clip use was associated with decreased Abbreviated Injury Scale (AIS) 2+ injury (odds ratio [OR] = 0.44, 95% confidence interval [CI], 0.21-0.91) and was not associated with neck injury. However, outcomes varied by age. In children <12 months old, chest clip use was associated with decreased AIS 2+ injury (OR = 0.09, 95% CI, 0.02-0.44). Neck injury (n = 7, all AIS 1) for this age group only occurred with correct cross-chest clip use. For 1- to 4-year-old children, cross-chest clip use had no association with AIS 2+ injury, and correct use significantly decreased the odds of neck injury (OR = 0.49; 95% CI, 0.27-0.87) compared to an incorrectly used or absent cross-chest clip. No serious injuries were directly caused by the chest clips. Correct cross-chest clip use appeared to reduce injury in crashes, and there was no evidence of serious clip-induced injury in children in 5-point harness restraints.

The Spinal Cord Injury (SCI) Longitudinal Aging Study was initiated in 1973 and has conducted 8 assessments over the past 40 years. It was designed to help rehabilitation professionals understand the life situation of people with SCI, but it has developed into the most long-standing study of aging and SCI and has resulted in over 50 publications. Our purpose was to provide a detailed history of the study, response patterns, utilization of measures, and a summary of key findings reported in the literature. Five participant samples have been incorporated over the 40 years, with enrollment in 1973, 1984, 1993 (2 samples), and 2003. A total of 2,208 participants have completed 6,001 assessments, with a particularly large number of assessments among those who are more than 40 years post injury (n = 349). The overall results have indicated changing patterns of outcomes over time as persons with SCI age, with some notable declines in participation and health. There has been a survivor effect whereby persons who are more active, well-adjusted, and healthier live longer. This study has several important features that are required for longitudinal research including (a) consistency of follow-up, (b) consistency of measures over time, (c) addition of new participant samples to counteract attrition, and (d) inclusion of a large number of individuals who have reached aging milestones unparalleled in the literature. Data from this study can inform the literature on the natural course of aging with SCI.

preservation of cognitive abilities is required to have a good quality of life. The predictive value of cognitive functioning at 65 years old on successful ageing 6 years later is not established. nine hundred and seventy-six questionnaires were sent by mail to a sample of healthy and voluntary French pensioners. Successful ageing was defined through health status and well-being. Cognitive abilities had been assessed 6 years earlier according to an objective method (Free and Cued Selective Recall Reminding Test (FCSRT), the Benton visual retention test and the similarities subtest of the Wechsler Adult Intelligence Scale-Revised) and a subjective one (Goldberg's anxiety scale, Mac Nair's scale and a Visual Analogue Scale to evaluate memory abilities change in the last 5 years). six hundred and eighty-six questionnaires could be analysed. The mean age was 72.9 ± 1.2 years old with 59% of women and 99% lived at home. Well-being was negatively correlated with the FCSRT (r = -0.08, P = 0.0318) but positively related with the Benton (r = 0.09, P = 0.0125) and the similarities tests (r = 0.09, P = 0.0118). There is a negative correlation between anxious and cognitive complaints measured at baseline, and successful ageing indicators 6 years later. preservation of cognitive abilities at the age of retirement can predict a successful ageing 6 years later.

To estimate (1) productive life years (PLYs) lost because of chronic conditions in Australians aged 45-64 years from 2010 to 2030, and (2) the impact of this loss on gross domestic product (GDP) over the same period. A microsimulation model, Health&WealthMOD2030, was used to project lost PLYs caused by chronic conditions from 2010 to 2030. The base population consisted of respondents aged 45-64 years to the Australian Bureau of Statistics Survey of Disability, Ageing and Carers 2003 and 2009. The national impact of lost PLYs was assessed with Treasury's GDP equation. Lost PLYs due to chronic disease at 2010, 2015, 2020, 2025 and 2030 (ie, whole life years lost because of chronic disease); the national impact of lost PLYs at the same time points (GDP loss caused by PLYs); the effects of population growth, labour force trends and chronic disease trends on lost PLYs and GDP at each time point. Using Health&WealthMOD2030, we estimated a loss of 347,000 PLYs in 2010; this was projected to increase to 459,000 in 2030 (32.28% increase over 20 years). The leading chronic conditions associated with premature exits from the labour force were back problems, arthritis and mental and behavioural problems. The percentage increase in the number of PLYs lost by those aged 45-64 years was greater than that of population growth for this age group (32.28% v 27.80%). The strongest driver of the increase in lost PLYs was population growth (accounting for 89.18% of the increase), followed by chronic condition trends (8.28%). Our study estimates an increase of 112 000 lost PLYs caused by chronic illness in older workers in Australia between 2010 and 2030, with the most rapid growth projected to occur in men aged 55-59 years and in women aged 60-64 years. The national impact of this lost labour force participation on GDP was estimated to be $37.79 billion in 2010, increasing to $63.73 billion in 2030.

To investigate the physical growth and psychomotor development of very low birth weight (VLBW) preterm infants in the first year after birth and related influencing factors. A total of 61 VLBW preterm infants received growth and development monitoring for 12 months. Z score was used to evaluate parameters for physical growth, and Denver Development Screen Test (DDST) was used for development screening. Among the 61 VLBW preterm infants, 27 (44.3%) were small-for-gestational-age (SGA) infants, and 34 (55.7%) were appropriate-for-gestational-age (AGA) infants. During the 1-year follow-up, the median weight-for-age Z-score (WAZ), height-for-age Z-score (HAZ), head circumference-for-age Z-score (HCZ), and weight-for-height Z score (WHZ) were >-1 SD in all age groups. The peaks of body mass index-for-age Z-score (BAZ) and WHZ appeared at 1 month of corrected age. At a corrected age of 40 weeks, the incidence rates of underweight, growth retardation, emaciation, microcephalus, overweight, and obesity were 15%, 16%, 11%, 13%, 20%, and 10%, respectively. Compared with those with a corrected age of 40 weeks, the infants with a corrected age of 6 months or 9-12 months had a significantly reduced incidence rate of overweight (3%) (P<0.05). Up to 1 year after birth, 15 infants (25%) had abnormal developmental quotient (DQ). The SGA group had a significantly higher incidence rate of abnormal DQ than the AGA group (P<0.05). SGA was the independent risk factor for retarded growth in the first year after birth in VLBW preterm infants. VLBW preterm infants experience an obvious growth deviation within 3 months of corrected age. Within the first year after birth, the proportion of infants with abnormal DQ screened by DDST is high.

To measure the force required for correcting pectus carinatum to the desired position and investigate the correlations of the required force with patients' gender, age, deformity type, severity and body mass index (BMI). A total of 125 patients with pectus carinatum were enrolled in the study from August 2013 to August 2016. Their gender, age, deformity type, severity and BMI were recorded. A chest wall compressor was used to measure the force required for correcting the chest wall deformity. Multivariate linear regression was used for data analysis. Among the 125 patients, 112 were males and 13 were females. Their mean age was 13.7±1.5 years old, mean Haller index was 2.1±0.2, and mean BMI was 17.4±1.8 kg/m 2 . Multivariate linear regression analysis showed that the desirable force for correcting chest wall deformity was not correlated with gender and deformity type, but positively correlated with age and BMI and negatively correlated with Haller index. The desirable force measured for correcting chest wall deformities of patients with pectus carinatum positively correlates with age and BMI and negatively correlates with Haller index. The study provides valuable information for future improvement of implanted bar, bar fixation technique, and personalized surgery. Retrospective study. Level 3-4. Copyright © 2018.

2018-05-01

Gender differences in play behavior and physical aggression have been consistently reported. Theoretical perspectives concerning evolutionary, social, and social-cognitive mechanisms suggest that male-typical play behavior during childhood increases subsequent physical aggression. The evidence supporting these connections is limited, however. The present study investigated the association between gender-typed play behavior in early childhood and physical aggression in early adolescence using a sample drawn from a longitudinal, population study, the Avon Longitudinal Study of Parents and Children. Based on gender-typed play behavior as measured by the Pre-School Activities Inventory at age 3.5 years, samples of masculine (64 boys, 60 girls), feminine (80 boys, 66 girls), and randomly selected control children (55 boys, 67 girls) were recruited at age 13 years and administered the Reinisch Aggression Inventory. After controlling for a range of sociodemographic variables, maternal characteristics, and behavioral problems, including hyperactivity and conduct problems at age 3.5, significant group differences in physical aggression at age 13 were found among children classified as masculine, control, and feminine at age 3.5. Masculine children exhibited significantly more physical aggression than control children or feminine children, and control children exhibited significantly more physical aggression than feminine children. The association between gender-typed play behavior and physical aggression was not moderated by sex. These results suggest that the degree of childhood gender-typed play behavior independently predicts the degree of physical aggression at adolescence in boys and in girls.

Objective Developing a useful tool for planning health care for children under 5 years of age in the Ciudad Bolivar locality of Bogotá, developing an endemic channel for acute respiratory disease and acute diarrheal disease in children under 5 years of age for the period of 2008 to 2012. Methodology Descriptive study with a focus on public health surveillance for the preparation of an endemic channel for children under 5 years receiving care services in the Vista Hermosa Hospital Level I. Results The incidence of acute respiratory disease for a period of five years was identified with a monthly average of 1265 + 79 cases, showing two annual peak periods. Acute diarrheal disease, a monthly average of 243 cases was obtained with a period of higher incidence. Conclusion The correct preparation of the endemic channels in primary health care can provide alerts in a timely manner from the first level of care and guide decision-making in health and help achieve better network management services.

Early Selection versus Late Correction: Age-Related Differences in Controlling Working Memory Contents

We examined whether a reduced ability to ignore irrelevant information is responsible for the age-related decline of working-memory (WM) functions. By means of event-related brain potentials we will show that filtering is not out of service in older adults but shifted to a later processing stage. Participants performed a visual short-term memory task (change-detection task) in which targets were presented along with distractors. To allow early selection, a cue was presented in advance of each display, indicating where the targets were to appear. Despite this relatively easy selection criterion, older adults’ filtering was delayed as indicated by the amplitude pattern of the contralateral delay activity. Importantly, WM-equated younger adults did not show a delay indicating that the delay is specific to older adults and not a general phenomenon that comes with low WM capacity. Moreover, the analysis of early visual potentials revealed qualitatively different perceptual/attentional processing between the age groups. Young adults exhibited stronger distractor sensitivity that in turn facilitated filtering. Older adults, in contrast, seemed to initially store distractors and to suppress them after the fact. These early-selection versus late-correction modes suggest an age-related shift in the strategy to control the contents of WM. PMID:27253867

Objective HbA1c is associated with cardiovascular risk in persons without diabetes and cardiovascular risk accumulates over the life course. Therefore, insight in factors determining HbA1c from childhood onwards is important. We investigated (lifestyle) determinants of HbA1c at age 12 years and the effects of growth on change in HbA1c and the tracking of HbA1c between the age of 8 and 12 years. Study Design and Methods Anthropometric measurements were taken and HbA1c levels were assessed in 955 children without diabetes aged around 12 years participating in the PIAMA birth cohort study. In 363 of these children HbA1c was also measured at age 8 years. Data on parents and children were collected prospectively by questionnaires. Results We found no significant association between known risk factors for diabetes and HbA1c at age 12 years. Mean(SD) change in HbA1c between ages 8 and 12 years was 0.6(0.7) mmol/mol per year (or 0.1(0.1) %/yr). Anthropometric measures at age 8 and their change between age 8 and 12 years were not associated with the change in HbA1c. 68.9% of the children remained in the same quintile or had an HbA1c one quintile higher or lower at age 8 years compared to age 12 years. Conclusion The lack of association between known risk factors for diabetes and HbA1c suggest that HbA1c in children without diabetes is relatively unaffected by factors associated with glycaemia. HbA1c at age 8 years is by far the most important predictor of HbA1c at age 12. Therefore, the ranking of HbA1c levels appear to be fairly stable over time. PMID:25875773

This study follows the occurrence of refractive errors in population and the possible selection of the appropriate type of corrective aids. Objective measurement and subsequent determination of the subjective refraction of the eye is on essential act in opotmetric practice. The file represented by 615 patients (1230 eyes) is divided according to the refractive error of myopia, hyperopia and as a control group are listed emetropic clients. The results of objective and subjective values of refraction are compared and statistically processed. The study included 615 respondents. To determine the objective refraction the autorefraktokeratometer with Placido disc was used and the values of spherical and astigmatic correction components, including the axis were recorded. These measurements were subsequently verified and tested subjectively using the trial lenses and the projection optotype to the normal investigative distance of 5 meters. After this the appropriate corrective aids were then recommended. Group I consists of 123 men and 195 women with myopia (n = 635) of clients with an average age 39 +/- 18,9 years. Objective refraction - sphere: -2,57 +/- 2,46 D, cylinder: -1,1 +/- 1,01 D, axis of: 100 degrees +/- 53,16 degrees. Subjective results are as follows--the value of sphere: -2,28 +/- 2,33 D, cylinder -0,63 +/- 0,80 D, axis of: 99,8 degrees +/- 56,64 degrees. Group II is represented hyperopic clients and consists of 67 men and 107 women (n = 348). The average age is 58,84 +/- 16,73 years. Objective refraction has values - sphere: +2,81 +/- 2,21 D, cylinder: -1,0 +/- 0,94 D; axis 95 degree +/- 45,4 degrees. Subsequent determination of subjective refraction has the following results - sphere: +2,28 +/- 2,06 D; cylinder: -0,49 +/- 0,85 D, axis of: 95,9 degrees +/- 46,4 degrees. Group III consists from emetropes whose final minimum viasual acuity was Vmin = 1,0 (5/5) or better. Overall, this control group is represented 52 males and 71 females (n = 247). The average

Objectives To determine if chronic oxygen dependency (discharge home on supplemental oxygen) in children with bronchopulmonary dysplasia (BPD; defined as requirement for supplemental O2 at 36 weeks postmenstrual age) predicts neurodevelopmental disability rates and growth outcomes at 36 months corrected age (CA). Study Design Longitudinal cohort study. Setting Southern Alberta regional center located at high altitude. Participants Preterm infants weighing ≤1250 grams with no BPD, BPD, and BPD with chronic oxygen dependency. Main outcome measures Neurodevelopmental and growth outcomes. Results Of 1563 preterm infants admitted from 1995–2007, 1212 survived. Complete follow-up data were available for 1030 (85%) children. Children in BPD and BPD with chronic oxygen dependency groups had significantly lower birth weights, gestational ages, prolonged mechanical ventilation and oxygen supplementation and received more postnatal steroids, compared to those without BPD. Children with BPD and BPD with chronic oxygen dependency were more likely to be below the 5th centile in weight and height compared to those without BPD but there was little difference between the BPD and BPD with chronic oxygen dependency groups. After controlling for confounding variables, children who had BPD and BPD with chronic oxygen dependency had higher odds of neurodevelopmental disability compared to those without BPD [OR (odds ratio) 1.9 (95%CI 1.1 to 3.5) and OR 1.8 (1.1 to 2.9), respectively], with no significant difference between BPD and BPD with chronic oxygen dependency [OR 0.9 (95% CI 0.6 to 1.5)]. Conclusions BPD and BPD with chronic oxygen dependency in children predicts abnormal neurodevelopmental outcomes at 36 months CA. However, the neurodevelopmental disability rates were not significantly higher in BPD with chronic oxygen dependency children compared to children with BPD only. Compared to those without BPD, growth is impaired in children with BPD and BPD with chronic oxygen

Few studies have investigated differences in age- and gender-specific educational gradients in tobacco smoking among the whole range of adult age groups. We examined educational inequality in smoking among Japanese adults aged 25-94 years. Using a large nationally representative sample (167,925 men and 186,588 women) in 2010, prevalence of current smoking and heavy smoking among daily smokers and their inequalities attributable to educational attainment were analyzed according to sex and age groups. Among men aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 68.4% (95% confidence interval [CI], 66.0%-70.6%), and graduate school graduates had the lowest at 19.4% (95% CI, 17.2%-21.9%). High school graduates had the second highest current smoking prevalence (e.g., 55.9%; 95% CI, 54.9%-56.8% in men aged 25-34 years). Among men aged 75-94 years, the difference in current smoking across educational categories was small. A similar but steeper educational gradient in current smoking was observed among women. Among women aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 49.3% (95% CI, 46.3%-52.3%), and graduate school graduates had the lowest at 4.8% (95% CI, 2.9%-7.4%). Compared with older age groups, such as 65-94 years, younger age groups, such as 25-54 years, had higher estimates of inequality indicators for educational inequality in both current and heavy smoking in both sexes. Educational inequalities in current and heavy smoking were apparent and large in the young population compared with older generations. The current study provides basic data on educational inequalities in smoking among Japanese adults. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

This study examined the relationship between head growth and cognitive outcome at the age of five years in preterm infants born at less than 32 weeks of gestation from 2003 to 2009, as previous research has mostly focused on outcomes in toddlers. The head circumference of 273 very preterm infants born in Tyrol, Austria, was measured at birth, discharge, the corrected ages of three, 12 and 24 months and the chronological age of five years. Suboptimal head size was defined as a head circumference of more than one standard deviation below the mean. Full-scale intelligence quotient (IQ) at five years was determined using Wechsler Preschool and Primary Scales of Intelligence, third edition. Infants with a suboptimal head size at the age of three months had a significantly lower median IQ than those with a normal head size (90 [20-122] versus 98 [20-138], p = 0.001) and from three months onwards they were more likely to exhibit cognitive delay. A suboptimal head size from the age of three months was consistently related to a 10% lower IQ, and this study adds further evidence that head growth failure, especially during the early postdischarge period, is related to impaired cognitive abilities. ©2016 Foundation Acta Paediatrica.

2017-10-01

Parenting stress has been linked to child development issues in early preterm infants, but less is known about its effects on development in infants born late preterm. We examined relationships between parenting stress of 108 mothers and 108 fathers and development of late preterm infants born at 34 0/7 to 36 6/7 weeks gestation. At 4 months corrected age, mothers and fathers completed the Parenting Stress Index (PSI-3); mothers were primary caregivers in almost all families and completed the Ages and Stages Questionnaire (ASQ-2) on child development. Mothers reported significantly more stress than fathers on the PSI-3 Parent Domain. PSI-3 subscale scores from the Child Domain were significant predictors of mother-reported infant development as measured by the ASQ-2 in regression models: Reinforces Parent predicted Gross Motor, Mood predicted Communication, and Acceptability predicted Communication, Fine Motor, Problem Solving, and Personal -Social development scale scores. Experiences of parenting stress differed for mothers and fathers. Further research is required on specific dimensions of parenting stress related to development of late preterm infants. © 2017 Wiley Periodicals, Inc.

Positive life orientation (PLO) is considered an important dimension of successful aging. To investigate how self-reported PLO changed among home-dwelling people from age 70 to 80 and 85 years. A prospective, population-based 15-year follow-up study of the age cohort of 70-year-olds living in the city of Turku, Finland. The data were collected in 1991 by a postal questionnaire that was sent to all residents of Turku, Finland, born in 1920 (N=1530). Follow-ups using the same procedure were conducted in 2001 and 2006. PLO was assessed with the following items: life satisfaction, feeling needed, having plans for the future, having zest for life, feeling depressed, and suffering from loneliness. We created a PLO score from the answers to these questions, where 1 represented the best PLO and 0 the poorest. At baseline, the participants showed rather high levels of positive life orientation (PLO total score 0.83). PLO declined markedly after the 70-year-old participants reached the age of 80 and 85 years (p<.001). However, depressive feelings remained quite stable. The decrease was similar among men and women except for the items suffering from loneliness and feeling needed. At age 70 and 80 years women suffered more from loneliness than men, while men experienced feeling needed more than women. Positive life orientation declines during old age, especially from age 70 to 80 years. Thereafter the decline is less steep except for changes in future plans and feeling needed.

Correction of hypermobile flatfoot in children by molded insert.

PubMed

Bordelon, R L

1980-11-01

One hundred feet in 50 children between the ages of 3 and 9 years with a diagnosis of idiopathic hypermobile flatfoot had a custom-molded insert ordered. A specific method of casting, correcting the various components of the deformity was utilized. An 1/8-inch polypropolene insert was fabricated from the positive cast. The insert was worn in leather shoes with a long counter, steel shank, and Thomas heel. The flatfoot was evaluated and classified by measurement of the talometatarsal angle on a standing lateral X-ray. The insert was fabricated so that the standing lateral talometatarsal angle was corrected to neutral with the insert on the foot and the foot in the shoe. The preliminary reports indicate that a correction can be obtained at the rate of 0.41 degrees per month or approximately 5 degrees per year. There was no significant loss of motion of the foot or the ankle. Perhaps this regimen may be utilized in those children with a hypermobile flatfoot for whom treatment is advised.

OBJECTIVE To assess findings of mammography of and interventions resulting from breast cancer screening in women aged 40-49 years with no increased risk (typical risk) of breast cancer. METHODS This cross-sectional study evaluated women aged 40-49 years who underwent mammography screening in a mastology reference center in Recife, PE, Northeastern Brazil, between January 2010 and October 2011. Women with breast-related complaints, positive findings in the physical examination, or high risk of breast cancer were excluded. RESULTS The 1,000 mammograms performed were classified into the following Breast Imaging-Reporting and Data System (BI-RADS) categories BI-RADS 0, 232; BI-RADS 1, 294; BI-RADS 2, 294; BI-RADS 3, 16; BI-RADS 4A, 2; BI-RADS 5, 1. There was one case of grade II invasive ductal carcinoma and various interventions, including 469 ultrasound scans, 53 referrals to mastologists, 11 cytological examinations, and 8 biopsies. CONCLUSIONS Mammography screening in women aged 40-49 years with typical risk of breast cancer led to the performance of other interventions. However, it also resulted in increased costs without demonstrable efficacy in decreasing mortality. PMID:26039396

Kinematics is recommended for the quantitative assessment of upper limb movements. The aims of this study were to determine the age effects on upper limb kinematics and establish normative values in healthy subjects. Three hundred and seventy healthy subjects, aged 3-93 years, participated in the study. They performed two unidirectional and two geometrical tasks ten consecutive times with the REAplan, a distal effector robotic device that allows upper limb displacements in the horizontal plane. Twenty-six kinematic indices were computed for the four tasks. For the four tasks, nineteen of the computed kinematic indices showed an age effect. Seventeen indices (the accuracy, speed and smoothness indices and the reproducibility of the accuracy, speed and smoothness) improved in young subjects aged 3-30 years, showed stabilization in adults aged 30-60 years and declined in elderly subjects aged 60-93 years. Additionally, for both geometrical tasks, the speed index exhibited a decrease throughout life. Finally, a principal component analysis provided the relations between the kinematic indices, tasks and subjects' age. This study is the first to assess age effects on upper limb kinematics and establish normative values in subjects aged 3-93 years.

To investigate the impact of prevalence correction of population denominators on myocardial infarction (MI) incidence rates, rate ratios, and rate differences in Aboriginal vs. non-Aboriginal Western Australians aged 25-74 years during the study period 2000-2004. Person-based linked hospital and mortality data sets were used to estimate the number of prevalent and first-ever MI cases each year from 2000 to 2004 using a 15-year look-back period. Age-specific and -standardized MI incidence rates were calculated using both prevalence-corrected and -uncorrected population denominators, by sex and Aboriginality. The impact of prevalence correction on rates increased with age, was higher for men than women, and substantially greater for Aboriginal than non-Aboriginal people. Despite the systematic underestimation of incidence, prevalence correction had little impact on the Aboriginal to non-Aboriginal age-standardized rate ratios (6% and 4% underestimate in men and women, respectively), although the impact on rate differences was more marked (12% and 6%, respectively). The percentage underestimate of differentials was greater at older ages. Prevalence correction of denominators, while more accurate, is difficult to apply and may add modestly to the quantification of relative disparities in MI incidence between populations. Absolute incidence disparities using uncorrected denominators may have an error >10%. Copyright © 2011 Elsevier Inc. All rights reserved.

Each year, herpes zoster (HZ) affects 1 million U.S. adults, many of whom develop postherpetic neuralgia (PHN). Zoster vaccine is licensed for persons aged 50 years or older, but its cost-effectiveness for those aged 50 to 59 years is unknown. To estimate the cost-effectiveness of HZ vaccine versus no vaccination. Markov model. Medical literature. Adults aged 50 years. Lifetime. Societal. HZ vaccine. Number of HZ and PHN cases prevented and incremental cost per quality-adjusted life-year (QALY) saved. For every 1000 persons receiving the vaccine at age 50 years, 25 HZ cases and 1 PHN case could be prevented. The incremental cost-effectiveness ratio (ICER) for HZ vaccine versus no vaccine was $323 456 per QALY. In deterministic and scenario sensitivity analyses, the only variables that produced an ICER less than $100 000 per QALY were vaccine cost (at a value of $80) and the rate at which efficacy wanes. In probabilistic sensitivity analysis, the mean ICER was $500 754 per QALY (95% CI, $93 510 to $1 691 211 per QALY). At a willingness-to-pay threshold of $100 000 per QALY, the probability that vaccination would be cost-effective was 3%. Long-term effectiveness data for HZ vaccine are lacking for 50-year-old adults. Herpes zoster vaccine for persons aged 50 years does not seem to represent good value according to generally accepted standards. Our findings support the decision of the Advisory Committee on Immunization Practices not to recommend the vaccine for adults in this age group. None.

To elucidate the effect of early growth patterns on the metabolic sensitivity to adiposity, we examined the relationship between the homeostatic model assessment of insulin resistance (HOMA-IR) and body mass index (BMI) levels at 12 years of age in 101 boys and 91 girls in a birth cohort. Children with an increase in BMI from the ages of 1.5 to 3 years exhibited a greater increase of HOMA-IR per BMI increase at 12 years of age compared to those with a decrease in BMI or stable BMI from 1.5 to 3 years. This suggests that children who show an increase in BMI from 1.5 to 3 years, a period normally characterized by a decreased or stable BMI, are more prone to developing insulin resistance at 12 years of age.

To investigate the prevalence of blindness and moderate and severe visual impairment among adults aged 50 years or above in Shuangcheng City of Heilongjiang Province, China. It was a population-based cross-section study. Geographically defined cluster sampling was used in randomly selecting 5 841 individuals aged 50 years or above in 28 basic sample units in Shuangcheng City from September to December 2006. The survey was preceded by a pilot study where operational methods were refined and quality assurance evaluation was carried out. All participants were enumerated through village registers followed door-to-door visits.Eligible individuals were invited to receive visual acuity measurement and eye examination. Statistical analyses were performed using Stata/SE Statistical Software, release 9.0. Chi-square test was used to investigate the association of age, gender and education with presenting and best corrected visual acuity. Five thousands four hundreds and eighty-one individuals were enumerated and 5 047 persons were examined, the response rate was 92.08%. Based on the criteria of World Health Organization visual impairment classification in 1973, the prevalence of blindness and moderate and severe visual impairment defined as best corrected visual acuity was 1.72% (87/5 047) and 4.69% (237/5 047) respectively. The prevalence of blindness and moderate and severe visual impairment defined as presenting visual acuity was 1.90% (96/5 047) and 7.23% (365/5 047) respectively. The prevalence of blindness and moderate and severe visual impairment was higher in aged (trend χ(2)=674.44, P < 0.01), female (χ(2)=39.61, P < 0.01) and illiterate (trend χ(2)=142.82, P < 0.01) persons. Cataract (52.70%) was still the first leading cause of blindness and visual impairment. The percentage of the retinal diseases, including age-related macular degeneration, high myopic retinopathy and diabetic retinopathy was 11.31% among the eyes with blindness and moderate and severe visual

ABSTRACT Objective: To provide an update on trends in asthma mortality in Brazil for two age groups: 0-4 years and 5-34 years. Methods: Data on mortality from asthma, as defined in the International Classification of Diseases, were obtained for the 1980-2014 period from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. To analyze time trends in standardized asthma mortality rates, we conducted an ecological time-series study, using regression models for the 0- to 4-year and 5- to 34-year age groups. Results: There was a linear trend toward a decrease in asthma mortality in both age groups, whereas there was a third-order polynomial fit in the general population. Conclusions: Although asthma mortality showed a consistent, linear decrease in individuals ≤ 34 years of age, the rate of decline was greater in the 0- to 4-year age group. The 5- to 34-year group also showed a linear decline in mortality, and the rate of that decline increased after the year 2004, when treatment with inhaled corticosteroids became more widely available. The linear decrease in asthma mortality found in both age groups contrasts with the nonlinear trend observed in the general population of Brazil. The introduction of inhaled corticosteroid use through public policies to control asthma coincided with a significant decrease in asthma mortality rates in both subsets of individuals over 5 years of age. The causes of this decline in asthma-related mortality in younger age groups continue to constitute a matter of debate. PMID:28380185

We aimed to prospectively examine the relationship between overall diet quality (reflecting adherence to dietary guidelines) and successful aging in a population-based cohort of older adults. In this population-based cohort study, we analyzed 10-year follow-up data from 1,609 adults aged 49 years and older, who were free of cancer, coronary artery disease, and stroke at the baseline and who had complete dietary data. Dietary data were collected using a semiquantitative food frequency questionnaire. Total diet scores (TDS) were allocated for intake of selected food groups and nutrients for each participant as described in the national dietary guidelines. Higher scores indicated closer adherence to dietary guidelines. Successful aging was defined as the absence of disability, depressive symptoms, cognitive impairment, respiratory symptoms, and chronic diseases (cancer, coronary artery disease, and stroke). At 10-year follow-up, 610 (37.9%) participants had died and 249 (15.5%) participants aged successfully. After multivariable adjustment, each 1-unit increase in TDS at baseline was associated with a 8% increased odds of successful aging 10 years later, odds ratio 1.08 (95% confidence interval 1.00-1.15). Participants in the highest (high adherence to dietary guidelines) versus lowest quartile (poor adherence to guidelines) of TDS at baseline had 58% higher odds of successful aging after 10 years, odds ratio 1.58 (95% confidence interval 1.02-2.46). Greater compliance with recommended national dietary guidelines (higher diet quality) was associated with an increased likelihood of successful aging, as determined through a multidomain approach. © The Author 2015.

Congenital talipes equinovarus may be the most common congenital orthopedic condition requiring treatment. Nonoperative treatment including different methods is generally accepted as the first step in the deformity correction. Ignacio Ponseti introduced his nonsurgical approach to the treatment of clubfoot in the early 1940s. The method is reportedly successful in treating clubfoot in patients up to 9 years of age. However, whether age at the beginning of treatment affects the rate of effective correction and relapse is unknown. We have applied the Ponseti method successfully with some modifications for 11 patients with a mean age of 11.2 years (range, 6 to 19 years) with neglected and untreated clubbed feet. The mean follow-up was 15 months (12 to 36 months). Correction was achieved with a mean of nine casts (six to 13). Clinically, 17 out of 18 feet (94.4%) were considered to achieve a good result with no need for further surgery. The application of this method of treatment is very simple and also cheap in developing countries with limited financial and social resources for health service. To the best of the authors' knowledge, such a modified method as a correction method for clubfoot in older children and adolescents has not been applied previously for neglected clubfeet in older children in the literature.

Of the $120.4 billion spent by the Nation for personal health care in fiscal year 1976, 29% was spent for those aged 65 or older, 15% for those under age 19, and the remaining 56% for those aged 19-64. The average health bill reached $1,521 for the aged, $547 for the intermediate age group, and $249 for the young. Public funds financed 68% of the health expenses of the aged with Medicare and Medicaid together accounting for 59%. Private sources paid 74% of the health expenses of the young and 70% of the expenses of those aged 19-64. Third-party payments met 65% of the health expenditures of all those under age 65.

Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

Despite the sensitivity of neuropsychological tests to educational level, improved diagnostic accuracy for demographically corrected scores has yet to be established. Diagnostic efficiency statistics of Wechsler Adult Intelligence Scale-III (WAIS-III) and Wechsler Memory Scale-III (WMS-III) indices that were corrected for education, sex, and age (demographically corrected) were compared with age corrected indices in individuals aged 16 to 75 years with moderate to severe traumatic brain injury (TBI) and 12 years or less education. TBI participants (n = 100) were consecutive referrals to an outpatient rehabilitation service and met careful selection criteria. Controls (n = 100) were obtained from the WAIS-III/WMS-III standardization sample. Demographically corrected indices did not provide higher diagnostic efficiency than age corrected indices and this result was supported by reanalysis of the TBI group against a larger and unmatched control group. Processing Speed Index provided comparable diagnostic accuracy to that of combined indices. Demographically corrected indices were associated with higher cut-scores to maximize overall classification, reflecting the upward adjustment of those scores in a lower education sample. This suggests that, in clinical practice, the test results of individuals with limited education may be more accurately interpreted with the application of demographic corrections. Diagnostic efficiency statistics are presented, and future research directions are discussed.

Objective: To investigate how associations between education and brain structure in older age were affected by adjusting for IQ measured at age 11. Methods: We analyzed years of full-time education and measures from an MRI brain scan at age 73 in 617 community-dwelling adults born in 1936. In addition to average and vertex-wise cortical thickness, we measured total brain atrophy and white matter tract fractional anisotropy. Associations between brain structure and education were tested, covarying for sex and vascular health; a second model also covaried for age 11 IQ. Results: The significant relationship between education and average cortical thickness (β = 0.124, p = 0.004) was reduced by 23% when age 11 IQ was included (β = 0.096, p = 0.041). Initial associations between longer education and greater vertex-wise cortical thickness were significant in bilateral temporal, medial-frontal, parietal, sensory, and motor cortices. Accounting for childhood intelligence reduced the number of significant vertices by >90%; only bilateral anterior temporal associations remained. Neither education nor age 11 IQ was significantly associated with total brain atrophy or tract-averaged fractional anisotropy. Conclusions: The association between years of education and brain structure ≈60 years later was restricted to cortical thickness in this sample; however, the previously reported associations between longer education and a thicker cortex are likely to be overestimates in terms of both magnitude and distribution. This finding has implications for understanding, and possibly ameliorating, life-course brain health. PMID:27664981

Temperament and body weight from ages 4 to 15 years.

Sutin, A R; Kerr, J A; Terracciano, A

2017-07-01

In adulthood, conscientiousness and neuroticism are correlates of body weight and weight gain. The present research examines whether the childhood antecedents of these traits, persistence and negative reactivity, respectively, are associated with weight gain across childhood. We likewise examine sociability as a predictor of childhood weight gain and whether these three traits are associated with weight concerns and weight-management strategies in adolescence. Participants (N=4153) were drawn from the Longitudinal Study of Australian Children, an ongoing, population-based study of child and family health and well-being. At the baseline assessment, caregivers reported on their child's temperament. At every assessment from ages 4-5 to 14-15 years, study children were weighed and measured by trained staff; there were up to six biennial assessments of body mass index and waist circumference. At ages 14-15 years, study children (n=2975) also self-reported on their weight concerns and weight-management strategies. Study children rated lower in persistence or higher in negative reactivity in early childhood gained more weight between the ages of 4 and 15 years. Sociability was associated with weight gain among girls but not among boys. Lower persistence and higher negative reactivity at ages 4-5 years were also associated with greater weight concerns, restrained eating and use of unhealthy weight-management strategies at ages 14-15 years. Childhood traits related to conscientiousness and neuroticism are associated with objective weight gain across childhood and with concerns and strategies to manage weight in adolescence. These results are consistent with a lifespan perspective that indicates that trait psychological functioning contributes to health-related markers from childhood through old age.

Trends in induced abortion among Nordic women aged 40-44 years

Objectives Women aged 40-44 years in 2005 ought to have been subjected to much more influence on attitudes and knowledge on contraceptive methods during their fertile period than women who were in the same age span in 1975 when the abortion laws were introduced. Material From official statistics, the rates of induced abortion and birth rates in women aged 40-44 years were collected for Sweden, Denmark, Norway and Finland for each five-year during the period 1975-2005. Results With the exception of Sweden all other studied Scandinavian countries have lowered their abortion rates since 1975 (p < 0.001) and reduced the proportion of induced abortions in relation to birth rate (p < 0.001). In 2005 these countries also had lower rates of induced abortion than Sweden in the age group 40-44 years (p < 0.001). Conclusion There is a significant change in rates of induced abortion in women aged 40-44 years in Finland, Norway, Denmark, and at status quo in Sweden. 40-44 years in Finland, Norway, Denmark, and at status quo in Sweden. This indicates that family planning programs works well in the Nordic countries. The differences found may be assumed to possible diverging focus on attitudes or ethical considerations.

Teens who give birth at age 15-17 years are at increased risk for adverse medical and social outcomes of teen pregnancy. To examine trends in the rate and proportion of births to teens aged 15-19 years that were to teens aged 15-17 years, CDC analyzed 1991-2012 National Vital Statistics System data. National Survey of Family Growth (NSFG) data from 2006-2010 were used to examine sexual experience, contraceptive use, and receipt of prevention opportunities among female teens aged 15-17 years. During 1991-2012, the rate of births per 1,000 teens declined from 17.9 to 5.4 for teens aged 15 years, 36.9 to 12.9 for those aged 16 years, and 60.6 to 23.7 for those aged 17 years. In 2012, the birth rate per 1,000 teens aged 15-17 years was higher for Hispanics (25.5), non-Hispanic blacks (21.9), and American Indians/Alaska Natives (17.0) compared with non-Hispanic whites (8.4) and Asians/Pacific Islanders (4.1). The rate also varied by state, ranging from 6.2 per 1,000 teens aged 15-17 years in New Hampshire to 29.0 in the District of Columbia. In 2012, there were 86,423 births to teens aged 15-17 years, accounting for 28% of all births to teens aged 15-19 years. This percentage declined from 36% in 1991 to 28% in 2012 (p<0.001). NSFG data for 2006-2010 indicate that although 91% of female teens aged 15-17 years received formal sex education on birth control or how to say no to sex, 24% had not spoken with parents about either topic; among sexually experienced female teens, 83% reported no formal sex education before first sex. Among currently sexually active female teens (those who had sex within 3 months of the survey) aged 15-17 years, 58% used clinical birth control services in the past 12 months, and 92% used contraception at last sex; however, only 1% used the most effective reversible contraceptive methods. Births to teens aged 15-17 years have declined but still account for approximately one quarter of births to teens aged 15-19 years. These data highlight

Gender medicine requires a global analysis of an individual's life. Menopause and ageing induce variations of some cardiometabolic parameters, but, it is unknown if this occurs in a sex-specific manner. Here, some markers of oxidative stress, systemic inflammation, and endothelial dysfunction are analysed in men younger and older than 45 years and in pre- and postmenopausal women. Serum and plasma sample were assayed for TNF-α and IL-6, malondialdehyde and protein carbonyls and for methylated arginines using ELISA kits, colorimetric methods and capillary electrophoresis. Before body weight correction, men overall had higher creatinine, red blood cells and haemoglobin and lower triglycerides than women. Men younger than 45 years had lower levels of TNF-α and malondialdehyde and higher levels of arginine than age-matched women, while postmenopausal women had higher IL-6 concentrations than men, and higher total cholesterol, triglycerides, creatinine and IL-6 levels than younger women. Men younger than 45 years had lower total cholesterol and malondialdehyde than older men. After correction, some differences remained, others were amplified, others disappeared and some new differences emerged. Moreover, some parameters showed a correlation with age, and some of them correlated with each other as functions of ageing and ageing/menopausal status. Ageing/menopausal status increased many more cardiovascular risk factors in women than ageing in men, confirming that postmenopausal women had increased vascular vulnerability and indicating the need of early cardiovascular prevention in women. Sex-gender differences are also influenced by body weight, indicating as a matter of debate whether body weight should be seen as a true confounder or as part of the causal pathway.

Early life physical activity may help prevent obesity but is difficult to measure. The purpose of this study was to examine associations of age of achievement of gross motor milestones in infancy with adiposity at age 3 years. Seven forty one mother/infant dyads participated in a longitudinal study in Massachusetts. Exposures were age of attainment of 4 gross motor milestones—rolling over, sitting up, crawling, and walking. Outcomes were 3-year sum of subscapular and triceps skinfold thickness (SS + TR) for overall adiposity, their ratio (SS:TR) for central adiposity, and body mass index (BMI) z-score. We used linear regression models adjusted for confounders to examine motor milestone achievement and later adiposity. Rolling over (0.04, 95% CI: 0.008, 0.07) and sitting up (0.02, 95% CI: 0.001, 0.05) at ≥6 months were associated with increased SS:TR compared with attainment before 6 months. Walking at ≥15 months was associated with 0.98 mm higher SS + TR (95% CI: 0.05, 1.91) compared with walking before 12 months. Age at crawling was not associated with the outcomes. None of the milestones were associated with BMI z-score. Age of motor milestone achievement was only a modest predictor of adiposity. Later rolling over and sitting up were associated with greater central adiposity, and later age at walking was associated with greater overall adiposity at age 3 years. Although we controlled for birth weight and 6-month weight-for-length in our models, more detailed assessment of early adiposity prior to achievement of motor milestones is needed to help determine causality.

The aim of this cross-sectional study was to determine the associations between self-reported subjective physical and cognitive age, and actual physical and cognitive functions among community-dwelling older people aged 75 years and older. The sample comprised 275 older adults aged 75-91 years. Two questions were asked regarding subjective age: 'How old do you feel physically?' and 'How old do you feel cognitively?' To assess physical functions, we measured handgrip strength, knee extension strength, standing balance and walking speed. Tests of attention, executive function, processing speed and memory were performed to assess actual cognitive function. Subjective physical and cognitive age was associated with performance on all of the physical and cognitive tests, respectively (p < 0.01). We also found that older adults who reported themselves as feeling older than their chronological age had a slower walking speed and lower scores for word-list memory recall than those who did not report themselves as feeling older than their actual age. These findings suggest that promoting a fast walking speed and good memory function may help to maintain a younger subjective physical and cognitive age in older adults aged 75 years and older.

Subjects: Forty-one tournament participants (22 girls, 19 boys; 11–13 or 15–17 years old) who reported no history of knee sprain or surgery were recruited. Measurements: We used a Cybex II dynamometer to obtain isokinetic concentric peak torques relative to body mass (Nm/kg) at 60°/s for hamstrings and quadriceps bilaterally. From average peak torques, we determined ipsilateral hamstrings:quadriceps and homologous muscle-group ratios. Results: Correlations between hamstrings and quadriceps strength measures ranged from 0.78 to 0.97. Players 15–17 years old had greater relative hamstrings and quadriceps strength than 11- to 13-year-old athletes. Age and sex interacted significantly for quadriceps strength. The quadriceps strength of 15- to 17-year-old girls did not differ from that of 11- to 13-year-old girls, whereas 15- to 17-year-old boys had stronger quadriceps than 11- to 13-year-old boys. Boys 15–17 years old had greater quadriceps strength than girls 15–17 years old. Conclusions: This study is unique in providing normative data for the hamstrings and quadriceps strength of basketball players 11–13 and 15–17 years old. Age-related strength differences did not occur consistently between the sexes, as girls 11–13 and 15–17 years old had similar relative quadriceps strength. PMID:14608433

ABSTRACT Objective: Our aim was to analyze the effectiveness of oxybutynin for hyperhidrosis treatment in patients over 40 years. Methods: Eighty-seven patients aged over 40 years were divided into two groups. One group consisted of 48 (55.2%) patients aged between 40 and 49 years, and another was composed of 39 (44.8%) patients aged over 50 years (50 to 74 years). A comparative analysis of Quality of Life and level of hyperhidrosis between the groups was carried out 6 weeks after a protocol treatment with oxybutynin. A validated clinical questionnaire was used for evaluation. Results: In the younger age group, 75% of patients referred a “partial” or “great” improvement in level of hyperhidrosis after treatment. This number was particularly impressive in patients over 50 years, in which 87.2% of the cases demonstrated similar levels of improvement. Over 77% of patients in both groups demonstrated improvement in Quality of Life. Excellent outcomes were observed in older patients, in which 87.1% of patients presented “slightly better” (41%) or “much better” (46.1%) improvement. Conclusion: Patients aged over 40 years with hyperhidrosis presented excellent results after oxybutynin treatment. These outcomes were particularly impressive in the age group over 50 years, in which most patients had significant improvement in Quality of Life and in level of hyperhidrosis. PMID:24728245

Purpose To determine the association of age-related maculopathy susceptibility 2 (ARMS2) gene polymorphisms with the 3-year outcomes of photodynamic therapy (PDT) in wet age-related macular degeneration (wet AMD). Methods The single nucleotide polymorphism (SNP) at rs10490924 in the ARMS2 gene of 65 patients with wet AMD who underwent PDT was genotyped using the TaqMan assay. The clinical characteristics and the outcomes of PDT were compared among the three genotypes at rs10490924. A multivariate regression analysis was performed to evaluate the influence of the clinical cofactors on the association of rs10490924 with the visual outcome at 36 months after the first PDT. Results A significant difference was found among the genotypes in the age and the baseline lesion size. The patients with the GG genotype showed a significant improvement in vision, and the patients with the TT genotype showed a significant worsening of vision at all time points measured after the initial PDT. In the multivariate regression analysis, the number of the G allele at rs10490924 was associated with a significantly greater improvement in the baseline best-corrected visual acuity (BCVA) at 36 months after the first PDT. Conclusions ARMS2 variants are likely associated with the 3-year outcomes of PDT in patients with wet AMD. PMID:28761324

To examine associations between adverse childhood experiences (ACEs) and attention-deficit/hyperactivity disorder (ADHD) at age 9 years using longitudinal data and assess the extent to which ACEs during middle childhood are independently associated with ADHD at age 9 years. We conducted a secondary analysis of data from the Fragile Families urban birth cohort 5- and 9-year interviews. The sample was limited to children for whom mothers were the primary caregiver and mother-reported information on 8 ACEs and ADHD were available at age 5 and 9 years. We examined associations between ACEs and parent-reported ADHD at age 9 years using logistic regression and controlling for potential confounders. We included 1572 children; 48% were African American, 11% had parent-reported ADHD at age 9 years, 41% and 42% experienced ≥1 ACE by age 5 years and between the ages of 5 and 9 years, respectively. ACEs before age 5 years were associated with ADHD at age 9 years. One, 2, and ≥3 ACEs between age 5 and 9 years were associated with ADHD at age 9 years even after controlling for ACEs before age 5 years and ADHD at age 5 years (adjusted odds ratio [AOR], 1.9; 95% confidence interval [CI], 1.2-3; AOR, 2.1; 95% CI, 1.2-3.8; and AOR, 2.2; 95% CI, 1.1-4.3). In this study of urban children, ACEs occurring before age 5 years as well as between the ages of 5 and 9 years were associated with ADHD at age 9 years. Even after controlling for early childhood ACEs and ADHD at age 5 years, the association between ADHD and ACEs in middle childhood remained significant, highlighting the importance of screening and intervention throughout childhood.

To determine the relationship between the Test of Infant Motor Performance (TIMP) at 3 months and cognitive, language, and motor outcomes on the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) at 2 years of age in high-risk infants born preterm. One hundred and six infants (47 females, 59 males) born at earlier than 31 weeks gestational age were prospectively tested with the TIMP at 10 to 15 weeks after term age and were assessed again with the Bayley-III at 2 years corrected age. Sensitivity and specificity were calculated for various cut points of the TIMP z-score and Bayley-III composite scores of no more than 85. The TIMP z-scores at 10 to 15 weeks of age were significantly associated with all three subscales on the Bayley-III at 2 years of age (p<0.001). Using a TIMP z-score cutoff of -0.5, specificity was relatively high for cognitive (87%), language (88%), and motor (89%) outcomes, but sensitivity was low (cognitive 41%, language 49%, motor 57%). This study demonstrates that the TIMP is related to cognitive, language, and motor outcomes on the Bayley-III at 2 years of age in high-risk infants born preterm. The Test of Infant Motor Performance (TIMP) predicts Bayley Scales of Infant and Toddler Development, Third Edition outcomes at 2 years of age. The TIMP is relatively good at discriminating between children who will and will not have typical development. © 2018 Mac Keith Press.

Population-based studies following trajectories of depression in autism spectrum disorders (ASD) from childhood into early adulthood are rare. The role of genetic confounding and of potential environmental intermediaries, such as bullying, in any associations is unclear. To compare trajectories of depressive symptoms from ages 10 to 18 years for children with or without ASD and autistic traits, to assess associations between ASD and autistic traits and an International Statistical Classification of Diseases, 10th Revision (ICD-10) depression diagnosis at age 18 years, and to explore the importance of genetic confounding and bullying. Longitudinal study of participants in the Avon Longitudinal Study of Parents and Children birth cohort in Bristol, United Kingdom, followed up through age 18 years. Data analysis was conducted from January to November 2017. Depressive symptoms were assessed using the Short Mood and Feelings Questionnaire (SMFQ) at 6 time points between ages 10 and 18 years. An ICD-10 depression diagnosis at age 18 years was established using the Clinical Interview Schedule-Revised. Exposures were ASD diagnosis and 4 dichotomized autistic traits (social communication, coherence, repetitive behavior, and sociability). An autism polygenic risk score was derived using the Psychiatric Genomics Consortium autism discovery genome-wide association study summary data. Bullying was assessed at ages 8, 10, and 13 years. The maximum sample with complete data was 6091 for the trajectory analysis (48.8% male) and 3168 for analysis of depression diagnosis at age 18 years (44.4% male). Children with ASD and autistic traits had higher average SMFQ depressive symptom scores than the general population at age 10 years (eg, for social communication 5.55 [95% CI, 5.16-5.95] vs 3.73 [95% CI, 3.61-3.85], for ASD 7.31 [95% CI, 6.22-8.40] vs 3.94 [95% CI, 3.83-4.05], remaining elevated in an upward trajectory until age 18 years (eg, for social communication 7.65 [95% CI, 6

In 2015, persons aged 10-24 years who were treated for nonfatal assault injuries in emergency departments (EDs) in the United States accounted for 32% of the approximately 1.5 million patients of all ages that EDs treated for nonfatal assault injuries (1). CDC analyzed data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) to examine 2001-2015 trends in nonfatal assault injuries among youths treated in EDs, by sex and age group, and to assess current rates by sex, age group, mechanism of injury, and disposition (1). Rates for 2001-2015 were significantly higher among males than among females and among young adults aged 20-24 years than among youths aged 10-14 and 15-19 years. During 2011-2015, rates declined for all groups. The 2015 rate among persons aged 10-24 years was 753.2 per 100,000 population, the lowest in the 15-year study period. Despite encouraging trends, the assault rate among young persons remains high. Rates in 2015 were higher among males, persons aged 20-24 years, and those who incurred intentional strike or hit injuries. Nearly one in 10 patients were admitted to the hospital, transferred to another hospital, or held for observation. Youth violence prevention strategies, including primary prevention approaches that build individual skills, strengthen family relationships, or connect young persons treated in EDs to immediate and ongoing support, can be implemented to decrease injuries and fatalities (2).

Routine Eye Examinations for Persons 20-64 Years of Age

PubMed Central

2006-01-01

Executive Summary Objective The objective of this analysis was to determine the strength of association between age, gender, ethnicity, family history of disease and refractive error and the risk of developing glaucoma or ARM? Clinical Need A routine eye exam serves a primary, secondary, and tertiary care role. In a primary care role, it allows contact with a doctor who can provide advice about eye care, which may reduce the incidence of eye disease and injury. In a secondary care role, it can via a case finding approach, diagnose persons with degenerative eye diseases such as glaucoma and or AMD, and lead to earlier treatment to slow the progression of the disease. Finally in a tertiary care role, it provides ongoing monitoring and treatment to those with diseases associated with vision loss. Glaucoma is a progressive degenerative disease of the optic nerve, which causes gradual loss of peripheral (side) vision, and in advanced disease states loss of central vision. Blindness may results if glaucoma is not diagnosed and managed. The prevalence of primary open angle glaucoma (POAG) ranges from 1.1% to 3.0% in Western populations, and from 4.2% to 8.8% in populations of African descent. It is estimated up to 50% of people with glaucoma are aware that they have the disease. In Canada, glaucoma disease is the second leading cause of blindness in people aged 50 years and older. Tonometry, inspection of the optic disc and perimetry are used concurrently by physicians and optometrists to make the diagnosis of glaucoma. In general, the evidence shows that treating people with increased IOP only, increased IOP and clinical signs of early glaucoma or with normal-tension glaucoma can reduce the progression of disease. Age-related maculopathy (ARM) is a degenerative disease of the macula, which is a part of the retina. Damage to the macula causes loss of central vision affecting the ability to read, recognize faces and to move about freely. ARM can be divided into an early

Background Despite the perceived importance of early life nutrition for mental development, few studies have related gestational undernutrition to later-life cognitive functioning. We investigated the consequences of gestational exposure to the Dutch famine of 1944–45 for cognitive functioning at the age of 59 years. Methods We recruited men and women who were (i) born in birth clinics in Amsterdam, Rotterdam and Leiden, between January 1945 and March 1946, whose mothers experienced famine during or immediately preceding pregnancy (n = 354); (ii) born in the same three institutions during 1943 and 1947, whose mothers did not experience famine during this pregnancy (n = 292); or (iii) same-sex siblings of those in the first two categories (n = 311). We assessed cognitive performance at the age of 59 years by means of a comprehensive test battery. Results All cognitive functioning test scores were within normal ranges for this age group. There were no differences in cognitive performance at the age of 59 years between individuals exposed to gestational undernutrition and those without this exposure. For the general cognitive index, a summary measure across six functional domains (mean 100, standard deviation (SD) 15 points), famine exposure was associated with a decrease of 0.57 points [95% confidence interval (95% CI) −2.41 to 1.28] points. Individuals exposed to famine in gestational weeks 1–10 had a cognitive functioning index 4.36 (95% CI 8.04–0.67) points lower than those without this exposure. Within-sibling-pair analyses gave consistent results. Conclusion We found no overall association between maternal exposure to acute famine in pregnancy and cognitive performance of the offspring at the age of 59 years, but cannot rule out an association specific to early pregnancy exposure.

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

Evaluating population-based data of hematologic malignancies (HMs) in older adults provides prognostic information for this growing demographic. Incidence rates and one- and five-year relative survival rates were examined for specific HMs among adults ages ≥75 years using data from the Surveillance, Epidemiology and End Results (SEER) Program. Hematologic malignancy cases (Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), multiple myeloma (MM), acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML)) were reported to one of 18 SEER registries. Recent average annual (2010-2014) incidence rates and incidence trends from 1973 to 2014 were examined for cases ages ≥75 years. One- and five-year relative cancer survival rates were examined for adults ages ≥75 years diagnosed 2007-2013, with follow-up into 2014. From 1973 to 2014, incidence rates increased for NHL, MM, and AML, decreased for HL, and remained relatively stable for ALL, CLL, and CML among adults ages ≥75 years. The highest one- and five-year relative survival rates were observed among adults with CLL ages 75-84 years (1 year: 91.8% (95% CI = 91.8-90.8)) and 5 years: 76.5% (95% CI = 74.2-78.6)). The lowest one- and five-year survival rates were observed among adults with AML ages 75-84 (1 year: 18.2% (95% CI = 74.2-78.6) and 5 years: 2.7% (95% CI = 2.0-3.6)). Survival for older adults ages ≥75 years with HMs is poor, particularly for acute leukemia. Understanding the heterogeneity in HM outcomes among older patients may help clinicians better address the hematological cancer burden and mortality in the aging population. © 2018 The Authors.

Craniofacial growth changes in young children are not yet completely understood. Up-to-date references for craniofacial measurements are crucial for clinical assessment of orthodontic anomalies, craniofacial abnormalities and subsequent planning of interventions. To provide normal reference data and to identify growth patterns for craniofacial dimensions of European boys and girls aged 3-6 years. Using standard anthropometric methodology, body weight, body height and 23 craniofacial measurements were acquired for a cross-sectional sample of 681 healthy children (362 boys and 319 girls) aged 3-6 years from Germany, Italy and Lithuania. Descriptive statistics, correlation coefficients, percentage annual changes and percentage growth rates were used to analyse the dataset. Between the ages of 3-6 years, craniofacial measurements showed age- and sex-related patterns independent from patterns observed for body weight and body height. Sex-related differences were observed in the majority of craniofacial measurements. In both sexes, face heights and face depths showed the strongest correlation with age. Growth patterns differed by craniofacial measurement and can be summarised into eight distinct age- and sex-related patterns. This study provided reference data and identified sex- and age-related growth patterns of the craniofacial complex of young European children, which may be used for detailed assessment of normal growth in paediatrics, maxillofacial reconstructive surgery and possibly for forensic age assessment.

Purpose To evaluate demographic variations in the use of corrective lenses among adolescent children. Methods Cross-sectional analysis of 3,916 children 12-18 years who participated in the 1999-2002 National Health and Nutrition Examination Survey (NHANES) vision examination component, which included: questions regarding use of corrective lenses; distance visual acuity, with corrective lenses if available; and non-cycloplegic autorefraction. Results reflect population-level estimates. Results Overall, 32.2% (95% confidence interval [CI]: 29.5%-35.0%) reported wearing corrective lenses. Girls and those with any private insurance had greater adjusted odds of reporting wearing corrective lenses. In contrast, children aged 15 through 18 years versus those 12 through 14 years, and white children compared to Black or Hispanic children had greater adjusted odds of actually having them available at the time of NHANES participation. Although 12.6% (95% CI: 8.8%-16.3%) of those who did not have their previously prescribed corrective lenses available had 20/25 or better distance visual acuity in both eyes without correction, 26.9% (95% CI:21.6%-32.1%) with their corrective lenses had distance visual acuity of 20/40 or worse in at least one eye when using their corrective lenses. Limitations Near visual acuity was not measured and children with corrective lenses available only had their corrected distance visual acuity measured. No data regarding the accuracy of the NHANES assessment of distance visual acuity are available. Autorefraction was performed without cycloplegia. Conclusions Many adolescent children report wearing corrective lenses. Variations across demographic characteristics appear to be due to a combination of undertreatment, overtreatment, and compliance with previously recommended corrective lenses. PMID:18062494

Class III correction using an inter-arch spring-loaded module

PubMed Central

2014-01-01

Background A retrospective study was conducted to determine the cephalometric changes in a group of Class III patients treated with the inter-arch spring-loaded module (CS2000®, Dynaflex, St. Ann, MO, USA). Methods Thirty Caucasian patients (15 males, 15 females) with an average pre-treatment age of 9.6 years were treated consecutively with this appliance and compared with a control group of subjects from the Bolton-Brush Study who were matched in age, gender, and craniofacial morphology to the treatment group. Lateral cephalograms were taken before treatment and after removal of the CS2000® appliance. The treatment effects of the CS2000® appliance were calculated by subtracting the changes due to growth (control group) from the treatment changes. Results All patients were improved to a Class I dental arch relationship with a positive overjet. Significant sagittal, vertical, and angular changes were found between the pre- and post-treatment radiographs. With an average treatment time of 1.3 years, the maxillary base moved forward by 0.8 mm, while the mandibular base moved backward by 2.8 mm together with improvements in the ANB and Wits measurements. The maxillary incisor moved forward by 1.3 mm and the mandibular incisor moved forward by 1.0 mm. The maxillary molar moved forward by 1.0 mm while the mandibular molar moved backward by 0.6 mm. The average overjet correction was 3.9 mm and 92% of the correction was due to skeletal contribution and 8% was due to dental contribution. The average molar correction was 5.2 mm and 69% of the correction was due to skeletal contribution and 31% was due to dental contribution. Conclusions Mild to moderate Class III malocclusion can be corrected using the inter-arch spring-loaded appliance with minimal patient compliance. The overjet correction was contributed by forward movement of the maxilla, backward and downward movement of the mandible, and proclination of the maxillary incisors. The molar relationship was

An evidence-based approach to the creation of normative data: base rates of impaired scores within a brief neuropsychological battery argue for age corrections, but against corrections for medical conditions.

We detail a new approach to the creation of normative data for neuropsychological tests. The traditional approach to normative data creation is to make demographic adjustments based on observations of correlations between single neuropsychological tests and selected demographic variables. We argue, however, that this does not describe the implications for clinical practice, such as increased likelihood of misclassification of cognitive impairment, nor does it elucidate the impact on decision-making with a neuropsychological battery. We propose base rate analyses; specifically, differential base rates of impaired scores between theoretical and actual base rates as the basis for decisions to create demographic adjustments within normative data. Differential base rates empirically describe the potential clinical implications of failing to create an appropriate normative group. We demonstrate this approach with data from a short telephone-administered neuropsychological battery given to a large, neurologically healthy sample aged 45-85 years old. We explored whether adjustments for age and medical conditions were warranted based on differential base rates of spuriously impaired scores. Theoretical base rates underestimated the frequency of impaired scores in older adults and overestimated the frequency of impaired scores in younger adults, providing an evidence base for the creation of age-corrected normative data. In contrast, the number of medical conditions (numerous cardiovascular, hormonal, and metabolic conditions) was not related to differential base rates of impaired scores. Despite a small correlation between number of medical conditions and each neuropsychological variable, normative adjustments for number of medical conditions does not appear warranted. Implications for creation of normative data are discussed.

Aragonès, Josep Maria; Altimiras, Jacint; Alonso, Francisco; Roura, Pere; Alfonso, Sebastián; Bajo, Lorena

Idiopathic normal pressure hydrocephalus is usually observed in adults over 60 years of age. The highest incidence of cases is between 70 and 80 years-old, and it could be under-diagnosed in over 80 year-olds. A description is presented on the overall incidence and age group incidence, the delay in the diagnosis, and main outcomes. A descriptive study was performed on patients with idiopathic normal pressure hydrocephalus, in the population of Osona County during the years 2010-2015. The annual incidence rate was 4.43 per 100,000 inhabitants. The incidence increased with age; from 8.09 per 100,000 in the 60 to 69 years age group, to 23.61 per 100,000 in the 70-79 years age group of, and to 37.02 per 100,000 in the 80-89 years age. The delay in the diagnosis was 15.01 ± 10.35 months. All the patients improved after surgery, but only 73.3% of the patients maintained the improvement after one year. Idiopathic normal pressure hydrocephalus is an age related disease and probably underdiagnosed in the elderly. An early diagnosis and a clinical suspicion are essential in patients over 80 years old.

In 1964, The Melbourne Asthma Study was established to describe the spectrum and natural history of childhood asthma. To describe the clinical and lung function outcome of childhood asthma to the age of 50 years. Subjects were invited to complete an interviewer-administered questionnaire, skin prick testing, and measurement of lung function from the age of 7 years to the age of 50 years at 7-year intervals. Of 458 survivors (from the original 484 subjects at recruitment), 346 subjects (76%) participated, of whom, 197 completed lung function measurement. Asthma remission at the age of 50 years was 64% in those with wheezy bronchitis, 47% for those with persistent asthma, and 15% for those with severe asthma in childhood. Multivariable analysis identified severe asthma in childhood (odds ratio [OR] 11.9 [95% CI, 3.4-41.8]), female sex (OR 2.0 [95% CI, 1.1-3.6]), and childhood hay fever (OR 2.0 [95% CI, 1.0-4.0]) as risk factors for "current asthma" at age 50 years. There was no evidence of a difference in the rate of decline in FEV1 (mL/y, 95% CI) between the severe asthma group (15 mL/y [95% CI, 9-22 mL/y]) and all the other recruitment groups: control (16 mL/y [95% CI, 12-20 mL/y]), mild wheezy bronchitis (14 mL/y [95% CI, 8-19 mL/y]), wheezy bronchitis (16 mL/y [95% CI, 11-20 mL/y]), and persistent asthma (19 mL/y [95% CI, 13-24 mL/y]). The clinical and lung function outcome in adult life is strongly determined by asthma severity in childhood. The reduced lung function seen in adults is established in childhood and does not appear to decline more rapidly in adult years despite continuing symptoms.

The aim of this study was to evaluate the proportion of completed treatments and to study the factors affecting the full mouth dental rehabilitation in pediatric patients treated by undergraduate students at the College of Dental Medicine Teaching Clinics, University of Sharjah. A retrospective study was conducted on 270 children aged less than 12 years (mean age 7.6, SD 2.04). Comprehensive dental rehabilitation reports of child patients that were completed by final year dental undergraduate students from the year 2009 to 2011 were reviewed. Data on complete history, oral examination, dental charting, and treatment plan were collected from pediatric dentistry case sheet. Dental caries was charted using WHO 1997 criteria. Dental treatment needs and completion of dental care delivered to children involved in this study were assessed using DMFT/deft scores. Percentages of treatment provided included completed restorations (94%) and space management (84%) in primary dentition, whereas 98% of restoration and 94% of required sealants were completed in permanent dentition. The percentage of completed dental treatment including sealant placement was 61%. Age of the child and the number of decayed teeth present before the start of the treatment significantly correlated with the children in the incomplete treatment category (P < 0.05). Therefore, a worthy dental care was provided in a holistic approach to the children attending College of Dental Medicine training clinics. Age of the child and the number of decayed teeth were the factors affecting dental rehabilitation in children aged 3-12 years.

To assess the relationship between trajectories of maternal depression from pregnancy to the child's age of 5 years and children's emotional and behavioral difficulties at age 5 years. Mother-child pairs (n = 1183) from the EDEN mother-child birth cohort study based in France were followed from 24 to 28 weeks of pregnancy to the child's fifth birthday. Children's behavior at age 5 years was assessed with the Strengths and Difficulties Questionnaire. Maternal depression was assessed repeatedly with the Center for Epidemiological Studies Depression questionnaire (pregnancy, 3, and 5 years of age) and the Edinburgh Postnatal Depression Scale (4, 8, and 12 months postpartum). Homogeneous latent trajectory groups of maternal depression were identified within the study population and correlated with Strengths and Difficulties Questionnaire scores by the use of multivariate linear regression analyzes. Five trajectories of maternal symptoms of depression were identified: no symptoms (62.0%); persistent intermediate-level depressive symptoms (25.3%); persistent high depressive symptoms (4.6%); high symptoms in pregnancy only (3.6%); and high symptoms in the child's preschool period only (4.6%). Children whose mothers had persistent depressive symptoms--either intermediate or high--had the greatest levels of emotional and behavioral difficulties at age 5 years. In addition, compared with children whose mothers were never depressed, those whose mothers had high symptoms in the preschool period also had increased levels of emotional symptoms, conduct problems, and peer problems. Maternal depression symptoms are related to children's emotional and behavioral problems, particularly if they are persistent (29.9%) or occur during early childhood (4.6%).

Most head circumference growth references are useful during the first years of life, but they are also useful for older children when screening for developmental, neurological, and genetic disorders. We aimed to develop head circumference growth reference charts for age, height, and waist circumference for Turkish children aged 5-18 years. Head circumference, height, and waist circumference measurements were obtained from 5079 students aged 5-18 years from İzmit, Kocaeli Province, Turkey. The LMS method was used to construct reference centile curves. Head circumference measurements were strongly correlated with height (r=0.74), weight (r=0.76), and waist circumference (r=0.68). The mean head circumference values for boys were larger than those for girls at all ages. Compared with data from the United States, the World Health Organization, and other studies from Turkey, our data showed a decrease in head circumference at all ages for both sexes. Local growth charts can be used to evaluate head circumference growth in older Turkish children and adolescents.

To evaluate the natural history of bronchopulmonary dysplasia, we studied the same 32 patients at a mean age of 7 and 10 years. The group as a whole had normal height and weight percentiles, and each child grew along his or her established somatic growth curve. Although some children had abnormal values, the group maintained a normal mean total lung capacity and functional residual capacity. The mean residual volume and the residual volume/total lung capacity ratios were elevated at both ages. At age 7 years the 19 patients (59%) who had a forced expiratory volume in 1 second (FEV1) of less than 80% had "catch up" improvement by 10 years of age (65 +/- 11% to 72 +/- 16% of predicted value; p less than 0.05). All the children who had a normal FEV1 at 7 years of age continued to have a normal FEV1 at age 10 years. Resting single-breath carbon monoxide uptake by the lung was normal when measured at age 10 years. The majority of patients had a positive methacholine challenge test result at both ages, although there was a low incidence of clinically diagnosed asthma. This study demonstrates that patients with bronchopulmonary dysplasia who have normal lung function at age 7 have had normal lung growth and that those with evidence of mild to moderate lung disease have continued lung growth or repair, or both, during their school years.

Soccer players are required to anticipate and react continuously in a changing, relatively unpredictable situation in the field. Cognitive functions might be important to be successful in soccer. The current study investigated the relationship between cognitive functions and performance level in elite and sub-elite youth soccer players aged 13-17 years. A total of 47 elite youth soccer players (mean age 15.5 years, SD = 0.9) and 41 sub-elite youth soccer players (mean age 15.2 years, SD = 1.2) performed tasks for "higher-level" cognitive functions measuring working memory (i.e., Visual Memory Span), inhibitory control (i.e., Stop-Signal Task), cognitive flexibility (i.e., Trail Making Test), and metacognition (i.e., Delis-Kaplan Executive Function System Design Fluency Test). "Lower-level" cognitive processes, i.e., reaction time and visuo-perceptual abilities, were also measured with the previous tasks. ANOVA's showed that elite players outscored sub-elite players at the "higher-level" cognitive tasks only, especially on metacognition (p < .05). Using stepwise discriminant analysis, 62.5% of subjects was correctly assigned to one of the groups based on their metacognition, inhibitory control and cognitive flexibility performance. Controlling for training hours and academic level, MANCOVA's showed differences in favor of the elite youth soccer players on inhibitory control (p = .001), and cognitive flexibility (p = .042), but not on metacognition (p = .27). No differences were found concerning working memory nor the "lower-level" cognitive processes (p > .05). In conclusion, elite youth soccer players have better inhibitory control, cognitive flexibility, and especially metacognition than their sub-elite counterparts. However, when training hours are taken into account, differences between elite and sub-elite youth soccer players remain apparent on inhibitory control and cognitive flexibility in contrast to metacognition. This highlights the need for longitudinal

Background: Few studies have shown an association between prenatal phthalate exposure and adverse effects on neurodevelopment and behavior in young children. Objectives: We aimed to assess the relationship between prenatal exposure to phthalate esters and behavior syndromes in children at 8 years of age. Methods: A total of 122 mother–child pairs from the general population in central Taiwan were studied from 2000 to 2009. Mono-methyl phthalate (MMP), mono-ethyl phthalate (MEP), mono-butyl phthalate (MBP), mono-benzyl phthalate (MBzP), and three di-(2-ethylhexyl) phthalate (DEHP) metabolites—mono-2-ethylhexyl, mono-2-ethyl-5-hydroxyhexyl, and mono-2-ethyl-5-oxohexyl phthalates (MEHP, MEHHP, and MEOHP)—were measured in maternal urine collected during the third trimester of pregnancy using liquid chromatography–electrospray ionization–tandem mass spectrometry. Behavioral syndromes of children at 8 years of age were evaluated using the Child Behavior Checklist (CBCL). Associations between log10-transformed creatinine-corrected phthalate concentrations and standardized scores of the CBCL were estimated using linear regression models or multinomial logistic regressions with adjustments for potential confounders. Results: Externalizing problem scores were significantly higher in association with a 1-unit increase in log10-transformed creatinine-corrected concentrations of maternal MBP (β = 4.29; 95% CI: 0.59, 7.99), MEOHP (β = 3.74; 95% CI: 1.33, 6.15), and MEHP (β = 4.28 ; 95% CI: 0.03, 8.26) after adjusting for the child’s sex, intelligence, and family income. Meanwhile, MBP and MEOHP were significantly associated with Delinquent Behavior and Aggressive Behavior scores. The same pattern was found for borderline and/or clinical ranges. Conclusions: Our findings suggest positive associations between maternal DEHP and dibutyl phthalate (DBP) exposure and externalizing domain behavior problems in 8-year-old children.

2013-08-01

To evaluate the tooth brushing skills in children aged between 6 and 12 years and its relation with age, type of grip used, duration of brushing and gender. A total of 105 children aged between 6 and 12 years were divided into seven groups and their plaque scores, type of grip used and duration of brushing were assessed. The most preferred grip was the distal oblique (58.1 %). Oblique, distal oblique and power grips were more efficient (plaque reduction up to 70 %). Plaque removal efficacy improved with age (57 % in 6-year-olds and 82 % in 12-year-old children). Plaque reduction was greater when the duration of brushing was longer (82 % plaque reduction when the brushing time was >2.5 min). Overall, the mean duration of tooth brushing in children aged 6-12 years was 1.71 min (103 s). Tooth brushing skills improved with age and the duration of tooth brushing made a significant difference to the oral hygiene status of the child. The type of grip used and gender did not influence tooth brushing ability in this group of children. Tooth brushing skills were low in children younger than 10 years of age. Hence, parental supervision is considered necessary and recommended until 10 years of age.

OBJECTIVE Corrective surgery for spinal deformities can lead to neurological complications. Several reports have described spinal cord monitoring in surgery for spinal deformity, but only a few have included patients younger than 20 years with adolescent idiopathic scoliosis (AIS). The goal of this study was to evaluate the characteristics of cases with intraoperative transcranial motor evoked potential (Tc-MEP) waveform deterioration during posterior corrective fusion for AIS. METHODS A prospective database was reviewed, comprising 68 patients with AIS who were treated with posterior corrective fusion in a prospective database. A total of 864 muscles in the lower extremities were chosen for monitoring, and acceptable baseline responses were obtained from 819 muscles (95%). Intraoperative Tc-MEP waveform deterioration was defined as a decrease in intraoperative amplitude of ≥ 70% of the control waveform. Age, Cobb angle, flexibility, operative time, estimated blood loss (EBL), intraoperative body temperature, blood pressure, number of levels fused, and correction rate were examined in patients with and without waveform deterioration. RESULTS The patients (3 males and 65 females) had an average age of 14.4 years (range 11-19 years). The mean Cobb angles before and after surgery were 52.9° and 11.9°, respectively, giving a correction rate of 77.4%. Fourteen patients (20%) exhibited an intraoperative waveform change, and these occurred during incision (14%), after screw fixation (7%), during the rotation maneuver (64%), during placement of the second rod after the rotation maneuver (7%), and after intervertebral compression (7%). Most waveform changes recovered after decreased correction or rest. No patient had a motor deficit postoperatively. In multivariate analysis, EBL (OR 1.001, p = 0.085) and number of levels fused (OR 1.535, p = 0.045) were associated with waveform deterioration. CONCLUSIONS Waveform deterioration commonly occurred during rotation maneuvers

The increasing problem of population aging requires appropriate economic and health-related measures to mitigate its negative effects. The aim was to categorize the biological age of men between 20 and 70 years of age and assess its relationship to their physical activity and fitness. Data included morphological variables, total body water, the results of five Eurofit motor tests and the percentage of maximum heart rate (HR%), during a cardiovascular test of more than 1,400 20-70 year-old men living in Kraków. Biological age was estimated with regression equations. There were significant and consistent differences in physical fitness profiles between the three established groups of relations between biological and chronological age (biologically younger, equal, and older). These three categories of biological age were generally consistent with the regression analysis of physical fitness results, although declared physical activity seemed to be an independent factor. The selected morphological variables represent a set of characteristics useful for the determination of the biological age. The existing relationship between physical activity and biological age indicates that physical activity may contribute to the inhibition of involutional changes, even if it had only been performed regularly in the past.

The objective of the study was to evaluate preteen insulin and metabolic syndrome (MS) as independent predictors of impaired fasting glucose (IFG) and type 2 diabetes mellitus (T2DM) in black and white females by mean age of 24 years. This was a prospective cohort study. There were 8 measures of fasting glucose and insulin from mean age of 10 years through mean age of 24 years, and insulin also at mean age of 25 years. Childhood MS was defined by at least 3 abnormal values among waist circumference, triglyceride, high-density lipoprotein cholesterol, blood pressure, and glucose. Hyperinsulinemia was defined by insulin greater than or equal to race-specific 75th percentile. Patients with type 1 diabetes mellitus were excluded. The study was held in schools and in an outpatient clinical center. Participants were schoolgirls (260 white, 296 black). There was no intervention. The outcome measures were IFG (fasting glucose of at least 100 to 125 mg/dL) and T2DM (fasting glucose of at least 126 mg/dL). By the age of 24 years, there were 11 cases of T2DM (2%) and 108 cases of IFG (19%). By the age of 24 years, IFG + T2DM was present in 18% of women (73/412) who had normal insulin-no MS at the age of 10 years vs 28% (34/122) of those with high insulin-no MS at the age of 10 years (P = .014) and 67% (10/15) of those with high insulin + MS at the age of 10 years (P < .0001). By stepwise logistic regression, significant, independent, positive predictors of IFG + T2DM were first insulin measure in childhood, age at last sampling, childhood MS, change in body mass index over 15 years, and, separately, initial glucose of at least 100 mg/dL and average of all insulin quartile ranks over 15 years. The correlation between childhood insulin z score and insulin z score 15 years later was r = .30, P < .0001. Insulin and MS at a mean age of 10 years plus change in body mass index over 15 years, and 15-year average insulin rank independently predict IFG + T2DM by mean age of 24 years

Percutaneous triplanar femoral osteotomy correction for developmental coxa vara: a new technique.

Developmental coxa vara (DCV) is a well-known pediatric hip disorder that is associated with triplanar deformity of the proximal femur. Several techniques of proximal femur osteotomies have being cited in the literature, with variable outcomes. Recently, the authors have used a percutaneous technique with application of a low-profile Ilizarov external fixator for acute opening wedge correction of the femoral deformity associated with DCV. Five children (six affected hips) underwent the above procedure at an average age of 8 + 4 years. The average improvement in Hilgenreiner's epiphyseal angle was from 74 degrees before surgery to 33 degrees after surgery, the neck-shaft angle improved from 86 degrees to 137 degrees, and the articulo-trochanteric distance improved from -6 mm to +11 mm. Latest follow-up at a mean of 2.1 years after surgery showed satisfactory healing with no significant loss of correction in any case. This percutaneous technique offers several advantages over currently available methods for surgical correction of DCV.

More information is needed on "low-risk" preterm infants' neurological outcome so that they can be included in follow-up programs. A prospective study was performed to examine the regional brain volume changes compared to term children and to assess the relationship between the regional brain volumes to cognitive outcome of the low-risk preterm children at 9 years of age. Subjects comprised 22 preterm children who were determined to be at low risk for neurodevelopmental deficits with a gestational age between 28 and 33 weeks without a major neonatal morbidity in the neonatal period and 24 age-matched term control children term and matched for age, sex, and parental educational and occupational status. Regional volumetric analysis was performed for cerebellum, hippocampus, and corpus callosum area. Cognitive outcomes of both preterm and control subjects were assessed by Weschler Intelligence Scale for Children Revised (Turkish version), and attention and executive functions were assessed by Wisconsin Card Sorting Test and Stroop Test TBAG version. Low-risk preterm children showed regional brain volume reduction in cerebellum, hippocampus, and corpus callosum area and achieved statistical significance when compared with term control. When the groups were compared for all WISC-R subscale scores, preterm children at low risk had significantly lower scores on information, vocabulary, similarities, arithmetics, picture completion, block design, object assembly, and coding compared to children born at term. Preterm and term groups were compared on the Stroop Test for mistakes and corrections made on each card, the time spent for completing each card, and total mistakes and corrections. In the preterm group, we found a positive correlation between regional volumes with IQ, attention, and executive function scores. Additionally, a significant correlation was found between cerebellar volume and attention and executive function scores in the preterm group. Low-risk preterm

Asteroseismic forward modelling techniques are being used to determine fundamental properties (e.g. mass, radius, and age) of solar-type stars. The need to take into account all possible sources of error is of paramount importance towards a robust determination of stellar properties. We present a study of 34 solar-type stars for which high signal-to-noise asteroseismic data is available from multi-year Kepler photometry. We explore the internal systematics on the stellar properties, that is, associated with the uncertainty in the input physics used to construct the stellar models. In particular, we explore the systematics arising from: (i) the inclusion of the diffusion of helium and heavy elements; and (ii) the uncertainty in solar metallicity mixture. We also assess the systematics arising from (iii) different surface correction methods used in optimisation/fitting procedures. The systematics arising from comparing results of models with and without diffusion are found to be 0.5%, 0.8%, 2.1%, and 16% in mean density, radius, mass, and age, respectively. The internal systematics in age are significantly larger than the statistical uncertainties. We find the internal systematics resulting from the uncertainty in solar metallicity mixture to be 0.7% in mean density, 0.5% in radius, 1.4% in mass, and 6.7% in age. The surface correction method by Sonoi et al. and Ball & Gizon's two-term correction produce the lowest internal systematics among the different correction methods, namely, ˜1%, ˜1%, ˜2%, and ˜8% in mean density, radius, mass, and age, respectively. Stellar masses obtained using the surface correction methods by Kjeldsen et al. and Ball & Gizon's one-term correction are systematically higher than those obtained using frequency ratios.

Closed anterior scoring for prominent-ear correction revisited.

Thomas, S S; Fatah, F

2001-10-01

The closed-anterior-scoring technique has been used over the past 3 years to correct 56 prominent ears in 32 patients at the West Midlands Regional Plastic Surgery Unit at Wordsley Hospital. A review was carried out to assess the result of this surgical procedure. We briefly discuss the historical development of other surgical techniques for prominent-ear correction, and describe in detail the operative technique for this procedure, which includes closed scoring and suturing of the cartilage. We used this technique to treat 24 patients with bilateral prominent ears and eight patients with unilateral prominent ears. The series comprised 20 females and 12 males, 26 children and six adults. The age range was from 4 to 24 years old. There were two complications (an upper-pole recurrence and protrusion of a buried prolene suture). Patients were followed up for between 6 months and 3 years (mean: 1.5 years). This procedure is quick and technically easy to learn, with no anterior scars or posterior cartilage overlap. Minimal dissection is involved, leading to a low rate of complications. The learning curve is rapid; this paper represents the experience of a specialist trainee (SST) after he was taught the technique by the senior author.

Children with cleft palate demonstrate atypical speech sound development, which can influence their intelligibility, literacy and learning. There is limited documentation regarding how speech sound errors change over time in cleft palate speech and the effect that these errors have upon mono-versus polysyllabic word production. The objective of this study was to examine the phonetic and phonological speech skills of children with cleft palate at ages 3 and 5. A cross-sectional observational design was used. Eligible participants were aged 3 or 5 years with a repaired cleft palate. The Diagnostic Evaluation of Articulation and Phonology (DEAP) Articulation subtest and a non-standardised list of mono- and polysyllabic words were administered once for each child. The Profile of Phonology (PROPH) was used to analyse each child's speech. N = 51 children with cleft palate participated in the study. Three-year-old children with cleft palate produced significantly more speech errors than their typically-developing peers, but no difference was apparent at 5 years. The 5-year-olds demonstrated greater phonetic and phonological accuracy than the 3-year-old children. Polysyllabic words were more affected by errors than monosyllables in the 3-year-old group only. Children with cleft palate are prone to phonetic and phonological speech errors in their preschool years. Most of these speech errors approximate typically-developing children by 5 years. At 3 years, word shape has an influence upon phonological speech accuracy. Speech pathology intervention is indicated to support the intelligibility of these children from their earliest stages of development. Copyright © 2017 Elsevier B.V. All rights reserved.

Radiocarbon analyses of pollen, ostracodes, and total organic carbon (TOC) provide a reliable chronology for the sediments deposited in Bear Lake over the past 30,000 years. The differences in apparent age between TOC, pollen, and carbonate fractions are consistent and in accord with the origins of these fractions. Comparisons among different fractions indicate that pollen sample ages are the most reliable, at least for the past 15,000 years. The post-glacial radiocarbon data also agree with ages independently estimated from aspartic acid racemization in ostracodes. Ages in the red, siliclastic unit, inferred to be of last glacial age, appear to be several thousand years too old, probably because of a high proportion of reworked, refractory organic carbon in the pollen samples. Age-depth models for five piston cores and the Bear Lake drill core (BL00-1) were constructed by using two methods: quadratic equations and smooth cubic-splinefits. The two types of age models differ only in detail for individual cores, and each approach has its own advantages. Specific lithological horizons were dated in several cores and correlated among them, producing robust average ages for these horizons. The age of the correlated horizons in the red, siliclastic unit can be estimated from the age model for BL00-1, which is controlled by ages above and below the red, siliclastic unit. These ages were then transferred to the correlative horizons in the shorter piston cores, providing control for the sections of the age models in those cores in the red, siliclastic unit. These age models are the backbone for reconstructions of past environmental conditions in Bear Lake. In general, sedimentation rates in Bear Lake have been quite uniform, mostly between 0.3 and 0.8 mm yr-1 in the Holocene, and close to 0.5 mm yr-1 for the longer sedimentary record in the drill core from the deepest part of the lake.

Speech-correcting surgeries (pharyngoplasty) are performed to correct velopharyngeal insufficiency (VPI). This study aimed to analyze the need for speech-correcting surgery in children with isolated cleft palate (ICP) and to determine differences among cleft extent, gender, and primary technique used. In addition, we assessed the timing and number of secondary procedures performed and the incidence of operated fistulas. Retrospective medical chart review study from hospital archives and electronic records. These comprised the 423 consecutive nonsyndromic children (157 males and 266 females) with ICP treated at the Cleft Palate and Craniofacial Center of Helsinki University Hospital during 1990 to 2016. The total incidence of VPI surgery was 33.3% and the fistula repair rate, 7.8%. Children with cleft of both the hard and soft palate (n = 300) had a VPI secondary surgery rate of 37.3% (fistula repair rate 10.7%), whereas children with only cleft of the soft palate (n = 123) had a corresponding rate of 23.6% (fistula repair rate 0.8%). Gender and primary palatoplasty technique were not considered significant factors in need for VPI surgery. The majority of VPI surgeries were performed before school age. One fifth of patients receiving speech-correcting surgery had more than one subsequent procedure. The need for speech-correcting surgery and fistula repair was related to the severity of the cleft. Although the majority of the corrective surgeries were done before the age of 7 years, a considerable number were performed at a later stage, necessitating long-term observation.

The aim of this study was to evaluate the efficacy of a treat-and-extend (TAE) regimen using intravitreal injection of aflibercept (IVA) for typical age-related macular degeneration (tAMD). We retrospectively studied 61 treatment-naïve eyes with tAMD. Best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), number of injections, and complications during 2 years were evaluated. BCVA significantly improved by on average 0.13 logMAR units, and CMT and CCT significantly decreased after 2 years. The number of injections was on average 13.6. In the second year, eyes with classic choroidal neovascularization (CNV) needed significantly fewer treatments than eyes with occult CNV. Fourteen eyes, which developed subfoveal fibrosis, showed significantly poorer BCVA after 2 years. Subfoveal fibrosis was significantly common in classic CNV. A TAE regimen using IVA for tAMD might be effective for improving BCVA and exudative changes. The exudation may be suppressed with fewer treatments in classic CNV compared to occult CNV. © 2017 S.

Context Most studies of injured dancers have been carried out on professional adult dancers; data on young, nonprofessional injured dancers are sparse. Objective To identify the types of injuries sustained by recreational dancers and to examine their association with age, joint range of motion, body structure, age at menarche, presence of anatomic anomalies, and physical burden (ie, practice hours en pointe). Design Descriptive epidemiology study. Setting The Israel Performing Arts Medicine Center, Tel Aviv. Patients or Other Participants A total of 569 injured female dancers, aged 8 to 16 years. Main Outcome Measure(s) Dependent variables were 61 types of current injuries that were later classified into 4 major categories: knee injuries, foot and ankle tendinopathy, back injuries, and other injuries. Independent variables were age, joint range of motion, body size and shape, age at menarche, anatomic anomalies, and dance discipline (eg, hours of practice per week en pointe). Results At least 1 previous injury had been sustained by 42.4% of the dancers. The most common injuries involved the knee (40.4%), followed by other injuries (23.4%). The relative frequency of back injuries and tendinopathy decreased with age, whereas knee injuries increased. Types of injuries were significantly associated with ankle plantar flexion, hip external rotation, hip abduction, and knee flexion. Multinomial regression analysis revealed only 3 predictive variables (with other as baseline), all for back injury: scoliosis, age, and hip external rotation. Conclusions Joint range of motion and scoliosis may signal the potential for future injury. Young dancers (less than 10 years of age) should not be exposed to overload (especially of the back) or extensive stretching exercises. PMID:23672333

Dating young geomorphic surfaces using age of colonizing Douglas fir in southwestern Washington and northwestern Oregon, USA

Pierson, T.C.

2007-01-01

Dating of dynamic, young (<500 years) geomorphic landforms, particularly volcanofluvial features, requires higher precision than is possible with radiocarbon dating. Minimum ages of recently created landforms have long been obtained from tree-ring ages of the oldest trees growing on new surfaces. But to estimate the year of landform creation requires that two time corrections be added to tree ages obtained from increment cores: (1) the time interval between stabilization of the new landform surface and germination of the sampled trees (germination lag time or GLT); and (2) the interval between seedling germination and growth to sampling height, if the trees are not cored at ground level. The sum of these two time intervals is the colonization time gap (CTG). Such time corrections have been needed for more precise dating of terraces and floodplains in lowland river valleys in the Cascade Range, where significant eruption-induced lateral shifting and vertical aggradation of channels can occur over years to decades, and where timing of such geomorphic changes can be critical to emergency planning. Earliest colonizing Douglas fir (Pseudotsuga menziesii) were sampled for tree-ring dating at eight sites on lowland (<750 m a.s.l.), recently formed surfaces of known age near three Cascade volcanoes - Mount Rainier, Mount St. Helens and Mount Hood - in southwestern Washington and northwestern Oregon. Increment cores or stem sections were taken at breast height and, where possible, at ground level from the largest, oldest-looking trees at each study site. At least ten trees were sampled at each site unless the total of early colonizers was less. Results indicate that a correction of four years should be used for GLT and 10 years for CTG if the single largest (and presumed oldest) Douglas fir growing on a surface of unknown age is sampled. This approach would have a potential error of up to 20 years. Error can be reduced by sampling the five largest Douglas fir instead of the

Introduction Most head circumference growth references are useful during the first years of life, but they are also useful for older children when screening for developmental, neurological, and genetic disorders. We aimed to develop head circumference growth reference charts for age, height, and waist circumference for Turkish children aged 5–18 years. Methods Head circumference, height, and waist circumference measurements were obtained from 5079 students aged 5–18 years from İzmit, Kocaeli Province, Turkey. The LMS method was used to construct reference centile curves. Results Head circumference measurements were strongly correlated with height (r=0.74), weight (r=0.76), and waist circumference (r=0.68). The mean head circumference values for boys were larger than those for girls at all ages. Compared with data from the United States, the World Health Organization, and other studies from Turkey, our data showed a decrease in head circumference at all ages for both sexes. Conclusion Local growth charts can be used to evaluate head circumference growth in older Turkish children and adolescents. PMID:28360767

To ascertain the retirement intentions of a cohort of Australian general practitioners. Postal questionnaire survey of members of four Divisions of General Practice in Western Australia, sent out November 2007 - January 2008. A sample of 178 GPs aged 45-65 years. Intention to work in general practice until retirement; reasons for retiring before age 65 years; factors that might encourage working beyond chosen retirement age; and perceived obstacles to working in general practice. 63% of GPs intended to work to at least age 65 years, with men more likely to retire early. Of 63 GPs intending to retire early, 46% gave pressure of work, exhaustion and burnout as reasons for early retirement. Better remuneration, better staffing levels and more general support were incentives to continue working for 46% of the 64 GPs who responded to the question about incentives, and more flexible working hours, part-time work and reduced workload for 41%. Of 169 participants, 65% gave increasing bureaucracy, poor job satisfaction and disillusionment with the medical system or Medicare as obstacles to working in general practice in Australia, whereas workforce shortage, increasing patient demands and diminishing lifestyle through overwork were obstacles named by 48%. Many GPs are planning to retire early, reflecting an emerging trend among professionals and society generally. Declining job satisfaction, falling workforce numbers, excessive workload and increasing bureaucracy were recurrent concerns of older WA GPs considering premature retirement.

To report the visual outcome and refractive status in first 3 years of age in preterm infants suffered from laser-treated Type 1 retinopathy of prematurity (ROP): a 6-year review in Hong Kong DESIGN: Retrospective case series METHODOLOGY: Clinical records of all infants suffered from Type 1 ROP who had undergone laser therapy between 2007 and 2012 were retrospectively reviewed. Basic demographic data, serial changes of refractive error, visual acuity, severity of ROP and laser were analyzed. Correlation with myopia and astigmatism progression, body weight, height, growth and gestational age were also analyzed. Among 494 babies screened, 14 Chinese babies (26 eyes) recruited with 1:1 male-to-female ratio in this study. All eyes showed gradual progression of myopia in first 3 years of age but no significant change of astigmatism. Further correlation analysis showed no correlation with laser energy consumed, birth weight (p = 0.14), head circumference growth (p = 0.57) and body weight growth (p = 0.71). However, severity of myopia was related to the post-conceptual age when receiving laser therapy (p < 0.005), gestation age (p = 0.02) and possibly body height growth with age (p = 0.05). Myopia in early life is one of the most common ocular sequelae in Type 1 ROP survivors. Early detection of refractive error is important for prompt correction and visual rehabilitation to prevent amblyopia.

The MACAO curvature wavefront sensors have been designed as a generic adaptive optics sensor for the Very Large Telescope. Six systems have been manufactured and implemented on sky: four installed in the UTs Coudé train as an AO facility for the VLTI, and two in UT's instruments, SINFONI and CRIRES. The MACAO-VLTI have now been in use for scientific operation for more than a decade and are planned to be operated for at least ten more years. As second generation instruments for the VLTI were planned to start implementation in end of 2015, accompanied with a major upgrade of the VLTI infrastructure, we saw it as a good time for a rejuvenation project of these systems, correcting the obsolete components. This obsolescence correction also gave us the opportunity to implement improved capabilities: the correction frequency was pushed from 420 Hz to 1050 Hz, and an automatic vibrations compensation algorithm was added. The implementation on the first MACAO was done in October 2014 and the first phase of obsolescence correction was completed in all four MACAO-VLTI systems in October 2015 with the systems delivered back to operation. The resuming of the scientific operation of the VLTI on the UTs in November 2015 allowed to gather statistics in order to evaluate the improvement of the performances through this upgrade. A second phase of obsolescence correction has now been started, together with a global reflection on possible further improvements to secure observations with the VLTI.

Personality theory and research typically focus on chronological age as a key indicator of personality development. This study examines whether the subjective experience of age is an alternative marker of the biomedical and psychosocial factors that contribute to individual differences in personality development. The present study uses data from the Midlife in the United States longitudinal survey (N = 3,617) to examine how subjective age is associated with stability and change in personality and the dynamic associations between subjective age and personality traits over a 10-year period. Regression analyses indicated that a younger subjective age at baseline was associated with increases in Openness, Conscientiousness, and Agreeableness; correlated changes were also found. The rank-order stability of Extraversion and Openness and overall profile consistency were higher among those with a younger subjective age at baseline and were also associated with the rate of subjective aging over time. The present study reveals that beyond chronological age, the age an individual feels is related to changes in characteristic ways of thinking, feeling, and behaving over time. © 2014 Wiley Periodicals, Inc.

SUMMARY Children with GERD may benefit from gastric acid suppression with proton pump inhibitors such as pantoprazole. Effective treatment with pantoprazole requires correct dosing and understanding of the drug’s kinetic profile in children. The aim of these studies was to characterize the pharmacokinetic (PK) profile of single and multiple doses of pantoprazole delayed-release tablets in pediatric patients with GERD aged ≥6 through 11 years (study 1) and 12 through 16 years (study 2). Patients were randomly assigned to receive pantoprazole 20 or 40 mg once daily. Plasma pantoprazole concentrations were obtained at intervals through 12 hours after the single dose, and at 2 and 4 hours after multiple doses for PK evaluation. PK parameters were derived by standard noncompartmental methods and examined as a function of both drug dose and patient age. Safety was also monitored. Pantoprazole PK was dose independent (when dose normalized) and similar toPK reported from adult studies. There was no evidence of accumulation with multiple dosing or reports of serious drug-associated adverse events. In children aged 6 to 16 years with GERD, currently available pantoprazole delayed-release tablets can be used to provide systemic exposure similar to that in adults. PMID:20852004

Given the heavy burden of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections in correctional facilities, we examined knowledge about these infections among case workers and correctional officers in penal institutions in Puerto Rico. We used data from a cross-sectional study of state prisons, commissioned by the Puerto Rico Department of Correction and Rehabilitation, to assess knowledge about HCV and HIV (10 items each) among 256 case workers and correctional officers from 18 penal institutions selected in the prison system. Total scores for each scale ranged from 0 to 10 points, with higher scores reflecting more knowledge. Of 256 participants, 64.8% were males, 39.6% were aged 30-39 years, and 70.3% were case workers. The percentage of correct responses for knowledge items ranged from 8.5% to 97.0% for HCV infection and from 38.7% to 99.6% for HIV infection. The vast majority (>96%) of participants knew that injection drug users should be tested for HCV infection and that sharing of needle injection equipment and multiple sex partners increase the risk of HIV infection. However, misconceptions about routes of transmission for these viral infections were found, with larger gaps in knowledge for HCV infection. Mean knowledge scores for HCV and HIV infections were 4.20±0.17 and 6.95±0.22, respectively, being significantly (p<0.05) higher for case workers. The findings about HCV and HIV knowledge in an important segment of the correctional system staff support the urgent need for increasing educational opportunities for correctional staff.

Hispanics are the fastest growing ethnicity in the United States, yet there are limited well-validated neuropsychological tools in Spanish, and an even greater paucity of normative standards representing this population. The Spanish NIH Toolbox Cognition Battery (NIHTB-CB) is a novel neurocognitive screener; however, the original norms were developed combining Spanish- and English-versions of the battery. We developed normative standards for the Spanish NIHTB-CB, fully adjusting for demographic variables and based entirely on a Spanish-speaking sample. A total of 408 Spanish-speaking neurologically healthy adults (ages 18-85 years) and 496 children (ages 3-7 years) completed the NIH Toolbox norming project. We developed three types of scores: uncorrected based on the entire Spanish-speaking cohort, age-corrected, and fully demographically corrected (age, education, sex) scores for each of the seven NIHTB-CB tests and three composites (Fluid, Crystallized, Total Composites). Corrected scores were developed using polynomial regression models. Demographic factors demonstrated medium-to-large effects on uncorrected NIHTB-CB scores in a pattern that differed from that observed on the English NIHTB-CB. For example, in Spanish-speaking adults, education was more strongly associated with Fluid scores, but showed the strongest association with Crystallized scores among English-speaking adults. Demographic factors were no longer associated with fully corrected scores. The original norms were not successful in eliminating demographic effects, overestimating children's performances, and underestimating adults' performances on the Spanish NIHTB-CB. The disparate pattern of demographic associations on the Spanish versus English NIHTB-CB supports the need for distinct normative standards developed separately for each population. Fully adjusted scores presented here will aid in more accurately characterizing acquired brain dysfunction among U.S. Spanish-speakers.

The aim of this study was to identify predictors of a superior functional outcome after corrective osteotomy for paediatric malunited radius and both-bone forearm fractures. We performed a systematic review and meta-analysis of individual participant data, searching databases up to 1 October 2016. Our primary outcome was the gain in pronosupination seen after corrective osteotomy. Individual participant data of 11 cohort studies were included, concerning 71 participants with a median age of 11 years at trauma. Corrective osteotomy was performed after a median of 12 months after trauma, leading to a mean gain of 77° in pronosupination after a median follow-up of 29 months. Analysis of variance and multiple regression analysis revealed that predictors of superior functional outcome after corrective osteotomy are: an interval between trauma and corrective osteotomy of less than 1 year, an angular deformity of greater than 20° and the use of three-dimensional computer-assisted techniques.

Ion chemistry of groundwater from the western part of the Roswell Basin, New Mexico, are consistent with groundwater quality evolution driven by dedolomitization. Measured, uncorrected, 14C values in groundwater yield an apparent residence time of 4700 years for the western part of the Roswell Basin. We have employed a simple model incorporating the changes in bicarbonate, magnesium and 14C along the flow-path to quantify the in-situ rate of dedolomitization and thereby to correct the 14C values for inorganic carbon dilution. The model yielded a corrected residence time of 1300 years at the distal end of the flowpath and a regional hydraulic conductivity of 5×10-4cm/s. Prior studies have inferred that underflow from the Sacramento Mountains constitutes an important component of recharge to the Artesian Aquifer of the Roswell Basin but it has not been possible to quantify this contribution. The information from the corrected 14C dating will allow an improved assessment of the groundwater resources available in this overstressed basin.

State-specific obesity prevalence data are critical to public health efforts to address the childhood obesity epidemic. However, few states administer objectively measured body mass index (BMI) surveillance programs. This study reports state-specific childhood obesity prevalence by age and sex correcting for parent-reported child height and weight bias. As part of the Childhood Obesity Intervention Cost Effectiveness Study (CHOICES), we developed childhood obesity prevalence estimates for states for the period 2005-2010 using data from the 2010 US Census and American Community Survey (ACS), 2003-2004 and 2007-2008 National Survey of Children's Health (NSCH) (n=133 213), and 2005-2010 National Health and Nutrition Examination Surveys (NHANES) (n=9377; ages 2-17). Measured height and weight data from NHANES were used to correct parent-report bias in NSCH using a non-parametric statistical matching algorithm. Model estimates were validated against surveillance data from five states (AR, FL, MA, PA and TN) that conduct censuses of children across a range of grades. Parent-reported height and weight resulted in the largest overestimation of childhood obesity in males ages 2-5 years (NSCH: 42.36% vs NHANES: 11.44%). The CHOICES model estimates for this group (12.81%) and for all age and sex categories were not statistically different from NHANES. Our modeled obesity prevalence aligned closely with measured data from five validation states, with a 0.64 percentage point mean difference (range: 0.23-1.39) and a high correlation coefficient (r=0.96, P=0.009). Estimated state-specific childhood obesity prevalence ranged from 11.0 to 20.4%. Uncorrected estimates of childhood obesity prevalence from NSCH vary widely from measured national data, from a 278% overestimate among males aged 2-5 years to a 44% underestimate among females aged 14-17 years. This study demonstrates the validity of the CHOICES matching methods to correct the bias of parent-reported BMI data and

Measuring Years of Inactivity, Years in Retirement, Time to Retirement, and Age at Retirement Within the Markov Model

Retirement-related concepts are treated as random variables within Markov process models that capture multiple labor force entries and exits. The expected number of years spent outside of the labor force, expected years in retirement, and expected age at retirement are computed—all of which are of immense policy interest but have been heretofore reported with less precisely measured proxies. Expected age at retirement varies directly with a person’s age; but even younger people can expect to retire at ages substantially older than those commonly associated with retirement, such as age 60, 62, or 65. Between 1970 and 2003, men allocated most of their increase in life expectancy to increased time in retirement, but women allocated most of their increased life expectancy to labor force activity. Although people can exit and reenter the labor force at older ages, most 65-year-old men who are active in the labor force will not reenter after they eventually exit. At age 65, the probability that those who are inactive will reenter the labor force at some future time is .38 for men and .27 for women. Life expectancy at exact ages is decomposed into the sum of the expected time spent active and inactive in the labor force, and also as the sum of the expected time to labor force separation and time in retirement.

Most of the published papers on Rheumatic Fever (RF) have not included the younger population. We selected 211 cases of children with RF younger than 6 years of age from 9,471 clinical files from 1944 to 1982. These were followed retrospectively to identify the presence of rheumatic activity, subsequent attacks and penicillin profilaxis. From de 211 cases, 209 had carditis; 57% of them were girls and 43% boys. There were no previous infections of the upper respiratory tract in 36% of the patients. The number of cases with RF increased abruptly after 3 years of age and continued increasing until 5 years of age when 70.5% of the population had there first clinically recognized attack. Lesions were present in the mitral valve in 80% of the cases, in the aortic valve in 12%, in the tricuspid in 5% and in the pulmonary valve in 3%. The death rate during the first attack was 20% being refractory heart failure the main cause of death. Thirteen cases suffered rheumatic pneumonia, 9 of whom died (69.2%). 1) The incidence of acute rheumatic fever in children under 6 years of age has decreased with time. 2) The death rate as well as the valvular damage decreased with the parents cooperation with the treatment. 3) The changes in the clinical picture and the severity of valve sequelea may be due to penicillin profilaxis and the better understanding of the disease.

Grammatical morphology continues to be widely regarded as an area of extraordinary difficulty in children with Specific Language Impairment (SLI). A main argument for this view is the purported high diagnostic accuracy of morphological errors for the identification of SLI. However, findings are inconsistent across age groups and across languages. Studies show morphological difficulty to be far less pronounced in more highly inflected languages and the diagnostic accuracy of morphology in such languages is largely unknown. This study examines the morphological use of Icelandic children with and without SLI in a cross-sectional sample of children ranging from preschool age to adolescence and assesses the usefulness of morphology as a clinical marker to identify SLI. Participants were 57 monolingual Icelandic-speaking children age 4-14 years; 31 with SLI and 26 with typical language development (TD). Spontaneous language samples were coded for correct and incorrect use of grammatical morphology. The diversity of use of grammatical morphemes was documented for each group at different age and MLU levels. Individual accuracy scores were plotted against age as well as MLU and diagnostic accuracy was calculated. MLU and morphological accuracy increased with age for both children with SLI and TD, with the two groups gradually approaching each other. Morphological diversity and sequence of acquisition was similar across TD and SLI groups compared based on age or MLU. Morphological accuracy was overall high, but was somewhat lower in the SLI group, in particular at ages below 12 years and MLU levels below 6.0. However, overlap between the groups was important in all age groups, involving a greater tendency for errors in both groups at young ages and scores close to or at ceiling at older ages. Sensitivity rates as well as likelihood ratios for each morpheme were all below the range considered acceptable for clinical application, whereas better specificity rates in some age

Objective To determine the effect of statistical correction for intra-individual variation on estimated urinary iodine concentration (UIC) by sampling on 3 consecutive days in four seasons in children. Setting School-aged children from urban and rural primary schools in Harbin, Heilongjiang, China. Participants 748 and 640 children aged 8–11 years were recruited from urban and rural schools, respectively, in Harbin. Primary and secondary outcome measures The spot urine samples were collected once a day for 3 consecutive days in each season over 1 year. The UIC of the first day was corrected by two statistical correction methods: the average correction method (average of days 1, 2; average of days 1, 2 and 3) and the variance correction method (UIC of day 1 corrected by two replicates and by three replicates). The variance correction method determined the SD between subjects (Sb) and within subjects (Sw), and calculated the correction coefficient (Fi), Fi=Sb/(Sb+Sw/di), where di was the number of observations. The UIC of day 1 was then corrected using the following equation: Results The variance correction methods showed the overall Fi was 0.742 for 2 days’ correction and 0.829 for 3 days’ correction; the values for the seasons spring, summer, autumn and winter were 0.730, 0.684, 0.706 and 0.703 for 2 days’ correction and 0.809, 0.742, 0.796 and 0.804 for 3 days’ correction, respectively. After removal of the individual effect, the correlation coefficient between consecutive days was 0.224, and between non-consecutive days 0.050. Conclusions The variance correction method is effective for correcting intra-individual variation in estimated UIC following sampling on 3 consecutive days in four seasons in children. The method varies little between ages, sexes and urban or rural setting, but does vary between seasons. PMID:26920442

The objective of this study was to obtain information about the current knowledge and habits of parents who transport children in cars in Brazil. A cross-sectional survey was conducted using specifically designed self-report questionnaires to parents of children attending a private pediatric office in a town in southwest Brazil. Data were collected regarding children's age, gender, height, and weight and possession of an automobile child restraint system (CRS), its type, frequency and adequacy of use, and reasons for not possessing or not using the devices. Parents were asked whether their cars were equipped with airbags and about the use of the restraints in seats with airbags. We interviewed parents of 293 children transported in cars who met the criteria for use of a CRS. Children were younger than 1 year in 15.3% of the cases, between 1 and 4 years in 38.6%, and older than 4 in 46.1%. Cars were equipped with CRS in 78.5% of the cases, but in only 58% of the cases was the device proper for child's age and adequately installed in the seat. Among owners of the devices, 84.3% reported that they always used it. Reasons for infrequency were forgetting the device at home or in another car (6.4%), the child disliking the device (3.2%), or the false impression that the child was grown enough not to use it (3.2%)l 87.1% did not justify why they did not always use the CRS. Considering type of CRS, correct installation of the seat, and frequency of use, only 44.4% of children under 1 year, 69.9% of those 1 to 4 years, and 52.6% over age 4 were protected. Only 28.6% of the parents knew that children should never be positioned in a seat with active airbags. Considering appropriateness for age, correctness of installation (in the back seat in the correct orientation), and frequency of use, only 50.85% (149/293) of the children were reported as always protected with a CRS. Children between 1 and 4 years were more likely to always use a CRS in this Brazilian survey. We were

Hundreds of Vaisala sondes with a RS80-H Humicap thin-film capacitor humidity sensor were launched during the Tropical Rainfall Measuring Mission (TRMM) field campaigns in Large Scale Biosphere-Atmosphere held in Brazil (LBA) and in Kwajalein experiment (KWAJEX) held in the Republic of Marshall Islands. Using Six humidity error correction algorithms by Wang et al., these sondes were corrected for significant dry bias in the RS80-H data. It is further shown that sonde surface temperature error must be corrected for a better representation of the relative humidity. This error becomes prominent due to sensor arm-heating in the first 50-s data.

Our objective was to determine scores on tests of neurocognitive functioning in children diagnosed with diabetes before age 10 years and to determine the association of age of diagnosis, duration of diabetes, subtle hypoglycemia, severe hypoglycemia, and history of hypoglycemic seizures with these neurocognitive test scores. Fifty-five of 62 eligible patients with a mean age of 7.9 +/- 1.6 years followed in our center were given the Woodcock-Johnson Psychoeducational Battery, Beery Developmental Test of Visual-Motor Integration, Finger Tapping, Grooved Pegboard, and Verbal Selective Reminding tests to evaluate the following domains: memory/attention, visual-perceptual, broad cognitive function, academic achievement, and fine motor speed/coordination. Fifteen age-matched siblings served as controls. Twenty-seven subjects were less than 5 years of age when diagnosed with diabetes, the mean age at diagnosis was 4.5 +/- 2.1 years of age, and mean diabetes duration was 2.6 +/- 2.0 years. Eighteen patients had a history of severe hypoglycemia, eight of whom had hypoglycemic seizures. The mean HbA1c was 7.8 +/- 1.1% for the year prior to testing. Our results showed that the overall mean scores for the extensive neurocognitive battery were within the normal range and were comparable to the scores of the age-matched sibling controls. Age of diagnosis and duration of diabetes did not relate to neurocognitive test results. Mean HbA1c had a negative association with some tests of memory/attention (p < 0.03-0.04) and academic achievement (p < 0.005-0.03), while number of blood glucose levels less than mg/dL had a positive association with memory/attention (p < 0.004-0.04), verbal comprehension (p < 0.03) and academic achievement (p < 0.018-0.05). There was no association of neurocognitive test scores with severe hypoglycemia, but subjects with history of hypoglycemic seizures had a decrease in scores on tests assessing memory skills (p < 0.03) including short term memory and

Deaths from unintentional injuries are the seventh leading cause of death among older adults (1), and falls account for the largest percentage of those deaths. Approximately one in four U.S. residents aged ≥65 years (older adults) report falling each year (2), and fall-related emergency department visits are estimated at approximately 3 million per year.* In 2016, a total of 29,668 U.S. residents aged ≥65 years died as the result of a fall (age-adjusted rate †  = 61.6 per 100,000), compared with 18,334 deaths (47.0) in 2007. To evaluate this increase, CDC produced age-adjusted rates and trends for deaths from falls among persons aged ≥65 years, by selected characteristics (sex, age group, race/ethnicity, and urban/rural status) and state from 2007 to 2016. The rate of deaths from falls increased in the United States by an average of 3.0% per year during 2007-2016, and the rate increased in 30 states and the District of Columbia (DC) during that period. In eight states, the rate of deaths from falls increased for a portion of the study period. The rate increased in almost every demographic category included in the analysis, with the largest increase per year among persons aged ≥85 years. Health care providers should be aware that deaths from falls are increasing nationally among older adults but that falls are preventable. Falls and fall prevention should be discussed during annual wellness visits, when health care providers can assess fall risk, educate patients about falls, and select appropriate interventions.

The pivotal approval trial for a smooth, highly cohesive, viscous, 20-mg/mL hyaluronic acid filler demonstrated sustained aesthetic improvement, with a mean injection volume of 6.65 mL. In daily practice, however, it is not often practical or necessary to use large injection volumes to achieve the desired cosmetic outcome. To assess the efficacy, longevity, and patient satisfaction associated with correction of age-related midface volume loss using the low volumes of hyaluronic acid filler more commonly used in day-to-day practice. A 2-center, retrospective cohort study examined medical records of 61 healthy patients who underwent treatment for facial volume loss with hyaluronic acid filler from November 1, 2013, through April 31, 2014. Follow-up visits were conducted at 1, 3, 6, and 12 months after the procedure. Data were pooled from a private facial plastic surgery practice in Weston, Florida, and a private cosmetic dermatology practice in San Diego, California. Patients were treated with hyaluronic acid filler according to the investigator's usual practices. The main outcome measure was patient-graded Global Aesthetic Improvement Scale scores at 1, 3, 6, and 12 months after treatment. Scores range from 1 to 5; 1 indicates very much improved and 5, worse. A total of 61 consecutive, healthy adult patients (mean [SD] age, 57.4 [12.8] years) with mild to severe facial volume loss were enrolled in the study. A total of 46 patients (75%) were white, 3 (5%) were black/African American, 9 (15%) were Hispanic/Latino, 1 (2%) was Asian/Pacific Islander, and 2 (3%) were other. Three patients (5%) were male, and 58 (95%) were female. Mean initial treatment volume was 1.6 mL. At follow-up, 29 patients (48%) elected to have a touch-up treatment; mean total touch-up volume was 1.4 mL. The patient-graded Global Aesthetic Improvement Scale scores at 1, 3, 6, and 12 months after treatment demonstrated that 73% (41 of 56) to 89% (24 of 27) of the study patients reported being very

Introduction The gradual shift of general paediatric surgery (GPS) provision from district general hospitals (DGH) to specialised units is well recognised in the UK. The consequences of centralisation include a reduction in exposure to GPS for current surgical trainees. The GPS practice of a DGH is examined here. Methods All operations performed on children aged under 5 years over a 5-year period were identified using the local electronic operation database. Electronic hospital records and clinic letters were accessed to collect data on demographics, operations performed and outcome measures. Results 472 GPS operations were performed on children between the age of 22 days and 5 years between 2009 and 2014, of which 43 were on an emergency basis and 105 were performed on patients aged less than 1 year. Three patients were admitted following day case surgery. Six patients were readmitted within 30 days. Complication rates for all procedures and the four most common procedures were similar to those found in published literature. Conclusions GPS for patients aged less than 5 years is comparatively safe in the DGH setting. The training opportunities available at DGHs are invaluable to surgical trainees and vital for sustaining the future provision of GPS by such hospitals.

Calibrating 15 years of GOLF data

The GOLF resonant scattering spectrophotometer aboard SoHO has now provided 15 years of continuous high precision Sun-as-a-star radial-velocity measurements. This length of time series provides very high resolution in the frequency domain and is combined with very good long-term instrumental stability. These are the requirements for measuring the low-l low-frequency global oscillations of the Sun that will unlock the secrets of the solar core. However, before the scientifically interesting gravity and mixed modes of oscillation fully reveal themselves, a correction and calibration of the whole data set is required. Here we present work towards producing a 15 year GOLF data set corrected for instrumental ageing and thermal variation.

To analyse the maternal identification of different stages of dental caries in children aged 1-3 years. A cross-sectional study was conducted with 274 children and their mothers. The mothers answered a questionnaire on the occurrence of dental caries in their children and completed questions addressing their demographic/socio-economic status. The oral examination of the children was performed using the International Caries Detection and Assessment System. Descriptive, Chi square test and Poisson regression statistical analyses were performed. The prevalence of initial and established/severe dental caries lesions by age were: 1 year (23.2 and 24.2%), 2 years (17.9 and 55.7%) and 3 years (23.3 and 60.3%) respectively. Significant associations between clinical examinations and the mothers' reports were observed among children aged 1 year old who had initial stage caries lesions (p = 0.006) and in children aged 1, 2 and 3 years old who had established/severe stage caries lesions (p < 0.001). After adjustment for confounding variables it was found that mothers were more able to identify dental caries both at initial (PR 4.01, 95% CI 1.35-11.94) and established/severe stages (PR 9.14, 95% CI 2.49-33.56) in children aged 1 year old. In children aged 2 and 3 years, this identification was more evident in the established/severe stage (2 years, PR 2.98, 95% CI 1.42-6.26; 3 years, PR 2.75, 95% CI 1.09-6.93). Mothers of children aged 1 year old identified dental caries at initial and established/severe stages. Mothers of children aged 2 and 3 years identified dental caries only at established/severe stages.

Research is limited on suicide attempts in children under 13 years of age. The objective of this study was to provide an in-depth description of this population. The present study is both retrospective and descriptive. Data were collected retrospectively from a file containing the causes for hospitalization of each child admitted into the Department of Child Psychiatry at the hôpital Femme-Mère-Enfant (hospices civils de Lyon). We included all patients under 13 years of age who were hospitalized for a suicide attempt between 2008 and 2011. The methods used to collect the medical records consisted in using a form made up of four major parts: suicide attempts, social environment, medical history, and therapy. The 26 girls and 22 boys included had a mean age of 11.52 years. The boys were younger than the girls (P=0.047) and their parents were usually separated (P=0.034). The boys used more violent means to commit suicide in comparison to the girls (P=0.048). On average, children using violent means were younger (P=0.013). Boys underwent more psychotherapy (P=0.027) and were prescribed more psychotropic medication in comparison to girls (P=0.051). Adjustment disorders (37.5%) and depression (27%) were the two main diagnoses for hospitalization. They were hospitalized on average (±standard deviation) 9.6 days (±10 days). Psychotherapy was organized when leaving the hospital (98%) with legal measures (8.3%), change of residence (12.5%), and prescription of psychotropic drugs (37.5%). None had physical complications. In children under 13 years of age, attempted suicide was more frequent in girls than boys. However, the sample included 18 girls and nine boys who were 12 years old (sex ratio of 12-year-olds, 0.5). There were more boys (16 boys/eight girls) in the children under 12 (sex ratio of 8- to 11-year-olds, 1.6). Children under 11 used more violent means (P=0.01). The literature also reports that more violent means lead to a greater risk of death by suicide

To investigate the relationship between lens power and age as well as the relationship between lens power and axial length (AL) in Chinese children and adolescents. The participants underwent a comprehensive ophthalmic examination that included AL, cycloplegic refraction, and Pentacam measurements. The crystalline lens power was calculated using Bennett's formula and then compared among the children of different age groups, refractive statuses, and AL categories. The association of lens power and AL was analyzed using multiple regression. A total of 1992 children and adolescents aged 6- to 18-years old were included. The difference in lens power was greater before 10-years old, followed by a relatively smaller difference in children aged 10 to 14 years and the difference in lens power came to a near plateau in adolescents after 14-years old. The negative association between lens power and AL was found to be more evident in nonmyopes than in myopes irrespective of age (younger than 10 years: nonmyopes: β = -1.499, myopes: β = -0.872; older than 10 years: nonmyopes: β = -1.288, myopes: β = -0.390, all P < 0.001). The lens power in children and adolescents aged 6 to 18 years exhibited three stages. The association between lens power and AL differed between the nonmyopes and myopes. These findings suggested that less reduction in lens power might be associated with both growing age and increasing AL in myopes.

Background: The purpose of this study was to confirm the utility of a corrected cephalometric analysis to facilitate the planning of distraction osteogenesis with Le Fort III osteotomy for syndromic craniosynostosis. Methods: This prospective study involved 4 male and 2 female patients (mean patient age, 8 years 9 months; age range, 4 years 6 months to 13 years 2 months) with Crouzon syndrome who were treated with Le Fort III maxillary distraction using our previously described system of analysis of a corrected cephalogram and who underwent clinical follow-up. Lateral cephalograms were obtained immediately after device removal. Results: Distraction of orbitale moved the vector downward to the adult profile, but there was slightly less elongation than the adult profile for the distraction distance. The desired and real mean angles after distraction of point A were 29.2 ± 7.9° and 6.1 ± 8.5°, respectively, and the desired and the real mean distances after distraction of point A were 30.6 ± 12.7 mm and 29.4 ± 4.1 mm, respectively. Conclusions: Using the corrected cephalometric analysis, the distance and vector of distraction osteogenesis with Le Fort III osteotomy could be determined in patients with syndromic craniosynostosis. The distraction system brought the patients' facial bones to the planned position using controlling devices. PMID:29062650

To investigate the prevalence of blindness and moderate and severe visual impairment among adults aged 50 years or above in Yangxi County of Guangdong Province, China. It was a population-based cross-section study.Geographically defined cluster sampling was used in randomly selecting 5 531 individuals aged 50 years or above in Yangxi County from September 2006 to January 2007. The survey was preceded by a pilot study where operational methods were refined and quality assurance evaluation was carried out. All participants were enumerated using village registers followed by door-to-door visits.Eligible individuals were invited to receive visual acuity measurement and eye examination.Statistical analyses were performed using Stata/SE Statistical Software, release 9.0. Chi-square test was used to investigate the association of age, gender and education with presenting and best corrected visual acuity. Five thousands five hundreds and thirty-one individuals were enumerated and 4 589 persons were examined, the response rate was 82.97%. Based on the criteria of World Health Organization visual impairment classification in 1973, the prevalence of blindness and moderate and severe visual impairment defined as best corrected visual acuity was 2.38% (109/4 589) and 9.44% (433/4 589) respectively. The prevalence of blindness and moderate and severe visual impairment defined as presenting visual acuity was 2.68% (123/4 589) and 18.15% (833/4 589) respectively. The prevalence of blindness and moderate and severe visual impairment was higher in aged (trend χ(2) = 1 239.34, P < 0.01) , female (χ(2) = 37.88, P < 0.01) and illiterate (trend χ(2) = 235.11, P < 0.01) persons. Cataract was the first leading cause of blindness and visual impairment. The prevalence of blindness and moderate and severe visual impairment is higher among older adults aged 50 years or above in Yangxi County. Cataract remains as the first leading cause of blindness and visual impairment.

Explore relationships among autonomic nervous system (ANS) function, child behavior, and maternal sensitivity in three-year-old children with surgically corrected transposition of the great arteries (TGA) and in children healthy at birth. Children surviving complex congenital heart defects are at risk for behavior problems. ANS function is associated with behavior and with maternal sensitivity. Child ANS function (heart rate variability) and maternal sensitivity (Parent-Child Early Relational Assessment) were measured during a challenging task. Mother completed the Child Behavior Checklist. Data were analyzed descriptively and graphically. Children with TGA had less responsive autonomic function and more behavior problems than healthy children. Autonomic function improved with more maternal sensitivity. Alterations in ANS function may continue years after surgical correction in children with TGA, potentially impacting behavioral regulation. Maternal sensitivity may be associated with ANS function in this population. Continued research on relationships among ANS function, child behavior, and maternal sensitivity is warranted.

Background. Children <2 years of age are at high risk of influenza-related mortality and morbidity. However, the appropriate dose of oseltamivir for children <2 years of age is unknown. Methods. The National Institute of Allergy and Infectious Diseases Collaborative Antiviral Study Group evaluated oseltamivir in infants aged <2 years in an age–de-escalation, adaptive design with a targeted systemic exposure. Results. From 2006 to 2010, 87 subjects enrolled. An oseltamivir dose of 3.0 mg/kg produced drug exposures within the target range in subjects 0–8 months of age, although there was a greater degree of variability in infants <3 months of age. In subjects 9–11 months of age, a dose of 3.5 mg/kg produced drug exposures within the target range. Six of 10 subjects aged 12–23 months receiving the Food and Drug Administration–approved unit dose for this age group (ie, 30 mg) had oseltamivir carboxylate exposures below the target range. Virus from 3 subjects developed oseltamivir resistance during antiviral treatment. Conclusions. The appropriate twice-daily oral oseltamivir dose for infants ≤8 months of age is 3.0 mg/kg, while the dose for infants 9–11 months old is 3.5 mg/kg.

The effects of age and gender on sleep EEG power spectral density were assessed in a group of 100 subjects aged 20 to 60 years. We propose a new statistical strategy (mixed-model using fixed-knot regression splines) to analyze quantitative EEG measures. The effect of gender varied according to frequency, but no interactions emerged between age and gender, suggesting that the aging process does not differentially influence men and women. Women had higher power density than men in delta, theta, low alpha, and high spindle frequency range. The effect of age varied according to frequency and across the night. The decrease in power with age was not restricted to slow-wave activity, but also included theta and sigma activity. With increasing age, the attenuation over the night in power density between 1.25 and 8.00 Hz diminished, and the rise in power between 12.25 and 14.00 Hz across the night decreased. Increasing age was associated with higher power in the beta range. These results suggest that increasing age may be related to an attenuation of homeostatic sleep pressure and to an increase in cortical activation during sleep.

The study included 107 patients, 62 women and 45 men hospitalized in the Institute of Psychiatry and Neurology and treated with ECT in 2013 and 2014. 76 people were below 60 years; 31 people - above 60. The authors analyzed the course of 1086 ECTs, 747 sessions for patients before 60 and 339 in patients over 60 years of age. The efficacy of ECT was diagnosed using CGI Scale. No serious complications such as death, life-threatening condition, hospitalization in another ward or permanent injury occurred. In 67.11% of patients below 60 and 42% of patients after 60 years of age no side effects were observed. Below 60 years of age most frequently reported adverse reactions were headaches (13.16% of patients), above 60 years of age - memory impairment (22.58% of respondents). Arrhythmias occurred in 6 patients aged over 60. Disturbances of consciousness occurred among older patients slightly less frequently than in younger patients (3.25% vs. 3.95%). In patients over 60 years of age remission rate was similar as in younger age group (32.89% vs 32.26%) and significant improvement rate was even higher (61.29% over 60 vs. 48.68 before 60 years of age). No improvement of mental state occurred in 7.89% and worsening occurred in 2.63% of younger patients. All patients ged over 60 years benefited from the treatment. The effectiveness of ECT in elderly was similar as in younger age group. The tolerance was slightly worse in patients aged over 60 years than in younger patients. The biggest problem in the elderly was not cognitive impairment, but the cardiovascular complications.

The authors examined whether early ultrasound dating (≤20 weeks) of gestational age (GA) in small-for-gestational-age (SGA) fetuses may underestimate gestational duration and therefore the incidence of SGA birth. Within a population-based case-control study (May 2002-June 2005) of Iowa SGA births and preterm deliveries identified from birth records (n = 2,709), the authors illustrate a novel methodological approach with which to assess and correct for systematic underestimation of GA by early ultrasound in women with suspected SGA fetuses. After restricting the analysis to subjects with first-trimester prenatal care, a nonmissing date of the last menstrual period (LMP), and early ultrasound (n = 1,135), SGA subjects' ultrasound GA was 5.5 days less than their LMP GA, on average. Multivariable linear regression was conducted to determine the extent to which ultrasound GA predicted LMP dating and to correct for systematic misclassification that results after applying standard guidelines to adjudicate differences in these measures. In the unadjusted model, SGA subjects required a correction of +1.5 weeks to the ultrasound estimate. With adjustment for maternal age, smoking, and first-trimester vaginal bleeding, standard guidelines for adjudicating differences in ultrasound and LMP dating underestimated SGA birth by 12.9% and overestimated preterm delivery by 8.7%. This methodological approach can be applied by researchers using different study populations in similar research contexts.

Performance assessment has become an invaluable component of monitoring player development and within talent identification programs in soccer, yet limited performance data are available for female soccer players across a wide age range. The aim of this study was to describe the physical performance characteristics of female soccer players ranging in age from 12 to 21 years. High-level female soccer players (n=414) were evaluated on linear sprinting (36.6 m with 9.1 m splits), countermovement jump (CMJ), and two agility tests. Separate one-way ANOVAs were used to compare performance characteristics between (1) each year of chronological age and (2) three age groups: 12-13 years, n=78, 14-17 years, n=223, and 18-21 years, n=113. Mean linear sprint speed over 9.1 m was similar across all chronological ages, however sprint speed over the final 9.1 m, CMJ height and agility scores improved until approximately 15-16 years. Outcomes from the group data indicated better performance on all tests for the 14-17-year-old group compared with the 12-13-year-old group. Additionally, sprint speed on the second and fourth 9.1 m splits and 36.6 m sprint speed as well as performance on the Illinois agility test was better in the 18-21-year-old group compared with the 14-17-year-old group. The findings from this study indicate that marked improvements of high intensity short duration work occur up until 15-16 years. Smaller gains in performance were observed beyond 16 years of age as evidenced by better performance on 36.6 m sprint speed, several sprint splits and the Illinois agility test in the college aged players (i.e., 18-21-year-old group). © 2010 John Wiley & Sons A/S.

Although early infant growth has implications for future health, body composition reference data in infancy are limited. The aim of this study was to describe reference data for fat mass (FM) and fat-free mass (FFM) corrected for length (L) within the first 3 months and to evaluate if these measures predict the body mass index (BMI) at 2 years. Term infants had air displacement plethysmography performed at birth (n = 1,063) and approximately 2 months later (n = 922, between 49 and 86 days). Age- and sex-specific reference data were generated for FM, FFM, FM/L 3 and FFM/L 2 and compared with BMI at 2 years. FM/L 3 and FFM/L 2 were the optimal indices independent of length. In the first 3 months, mean FM/L 3 increased (males, from 2.7 to 5.9 kg/m 3 ; females, from 3.2 to 6.1 kg/m 3 ), whereas FFM/L 2 remained relatively stable (males, from 11.8 to 12.7 kg/m 2 ; females, from 12.8 to 12.1 kg/m 2 ). The odds of a BMI Z-score ≥2 at 2 years increased with increasing FM (OR 2.7, 95% CI 1.97-3.7) and weight (OR 2.27, 95% CI 1.64-3.13) Z-scores at 2 months. FM/L 3 and FFM/L 2 provide length-independent measures of FM and FFM in infancy. During the first 3 months, there is an increase in FM/L 3 , but not in FFM/L 2 . The weight Z-score at 2 months is as good at predicting BMI at 2 years as body composition parameters. © 2016 S. Karger AG, Basel.

Increased survival rates for extremely preterm, extremely low birth weight infants during the postsurfactant era have been reported, but data on changes in neurosensory and developmental impairments are sparse. To compare neuromotor and neurodevelopmental outcomes at 18 to 22 months' corrected age for infants of <25 weeks' estimated gestational age (EGA) who were born in the 1990s. This was a multicenter, retrospective, comparative analysis of infants of <25 weeks' EGA, with birth weights of 501 to 1000 g, born between January 1993 and June 1996 (epoch I) or between July 1996 and December 1999 (epoch II), in the National Institute of Child Health and Human Development Neonatal Research Network. Neurodevelopmental assessments were performed at 18 to 22 months' corrected age. Logistic-regression models were constructed to evaluate the independent risk of cerebral palsy, Mental Development Index of <70, Psychomotor Development Index of <70, and neurodevelopmental impairment. A total of 366 patients in epoch I and 473 patients in epoch II were evaluated. Prenatal steroid use, cesarean section, surfactant treatment, bronchopulmonary dysplasia, and severe retinopathy of prematurity were more likely in epoch II, whereas Apgar scores of <5 at 5 minutes, patent ductus arteriosus, and severe intraventricular hemorrhage were more likely in epoch I. The prevalences of cerebral palsy, Psychomotor Development Index of <70, and neurodevelopmental impairment were similar between epochs. The prevalences of Mental Development Index of <70 were 40% for epoch I and 47% for epoch II. Regression analysis revealed that epoch II was an independent risk factor for Mental Developmental Index of <70 (epoch I versus II: odds ratio: 0.63; 95% confidence interval: 0.45-0.87) but not for other outcomes. Early childhood neurodevelopmental outcomes among infants of <25 weeks' EGA are not improving in the postsurfactant era, despite more aggressive perinatal and neonatal treatment. Later childhood

Phaeochromocytoma [corrected] crisis is an endocrine emergency associated with significant mortality. There is little published guidance on the management of phaeochromocytoma [corrected] crisis. This clinical practice update summarizes the relevant published literature, including a detailed review of cases published in the past 5 years, and a proposed classification system. We review the recommended management of phaeochromocytoma [corrected] crisis including the use of alpha-blockade, which is strongly associated with survival of a crisis. Mechanical circulatory supportive therapy (including intra-aortic balloon pump or extra-corporeal membrane oxygenation) is strongly recommended for patients with sustained hypotension. Surgical intervention should be deferred until medical stabilization is achieved. © 2013 John Wiley & Sons Ltd.

To demonstrate coronary artery wall thickening with age in a small healthy cohort using a highly efficient, reliable, and reproducible high-resolution MR technique. A 3D cross-sectional MR vessel wall images (0.7 × 0.7 × 3 mm resolution) with retrospective beat-to-beat respiratory motion correction (B2B-RMC) were obtained in the proximal right coronary artery of 21 healthy subjects (age, 22-62 years) with no known cardiovascular disease. Lumen and outer wall (lumen + vessel wall) areas were measured in one central slice from each subject and average wall thickness and wall area/outer wall area ratio (W/OW) calculated. Imaging was successful in 18 (86%) subjects with average respiratory efficiency 99.3 ± 1.7%. Coronary vessel wall thickness and W/OW significantly correlate with subject age, increasing by 0.088 mm and 0.031 per decade respectively (R = 0.53, P = 0.024 and R = 0.48, P = 0.046). No relationship was found between lumen area and vessel wall thickness (P = NS), but outer wall area increased significantly with vessel wall thickness at 19 mm(2) per mm (P = 0.046). This is consistent with outward vessel wall remodeling. Despite the small size of our healthy cohort, using high-resolution MR imaging and B2B-RMC, we have demonstrated increasing coronary vessel wall thickness and W/OW with age. The results obtained are consistent with outward vessel wall remodeling. Copyright © 2011 Wiley-Liss, Inc.

In 1983-1984, 4578 Perth primary and secondary schoolchildren were studied. The selected sample was broadly representative of the ethnic groups that make up the Perth population and of the different social ranks within that population. The age, sex, weight, height, country of birth of the child and the parents, and occupation of the father were recorded for each subject. Weight, height and body mass index (BMI) increased with age. Age and sex were the most important determinants of body size. However, children of lower social rank and those with a southern European background were over-represented among the overweight children (greater than the 90th centile for BMI), particularly in adolescence. Children with an Asian background who were 11 years of age and younger were over-represented among the underweight children (less than or equal to the 10th centile for BMI). Results from this study indicate a continuing, though small (1.5 cm to 1.6 cm), secular increase in height over the past 13 to 14 years.

A United States national sample of 20,962 participants (57% women, 44% blacks) from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study provided general population estimates for electrocardiographic (ECG) abnormalities among black and white men and women. The participants were recruited from 2003 to 2007 by random selection from a commercially available nationwide list, with oversampling of blacks and those from the stroke belt, with a cooperation rate of 49%. The measurement of risk factors and 12-lead electrocardiograms (centrally coded using Minnesota code criteria) showed 28% had ≥1 major ECG abnormality. The prevalence of abnormalities was greater (≥35%) for those ≥65 years old, with no differences between blacks and whites. However, among men <65 years, blacks had more major abnormalities than whites, most notably for atrial fibrillation, major Q waves, and left ventricular hypertrophy. Men generally had more ECG abnormalities than women. The most common ECG abnormalities were T-wave abnormalities. The average heart rate-corrected QT interval was longer in women than in men, similar in whites and blacks, and increased with age. However, the average heart rate was greater in women than in men and in blacks than in whites and decreased with age. The prevalence of ECG abnormalities was related to the presence of hypertension, diabetes, blood pressure, and age. In conclusion, black men and women in the United States have a significantly greater prevalence of ECG abnormalities than white men and women at age 45 to 64 years; however, these proportions, although larger, tended to equalize or reverse after age 65.

Due to their minute size, 40Ar/39Ar analysis of illite faces significant analytical challenges, including mineral characterization and, especially, effects of grain size and crystallography on 39Ar recoil. Quantifying the effects of 39Ar recoil requires the use of sample vacuum encapsulation during irradiation, which permits the measurement of the fraction of recoiled 39Ar as well as the 39Ar and 40Ar∗ retained within illite crystals that are released during step heating. Total-Gas Ages (TGA) are calculated by using both recoiled and retained argon, which is functionally equivalent to K-Ar ages, while Retention Ages (RA) only involve retained Ar in the crystal. Natural applications have shown that TGA fits stratigraphic constraints of geological processes when the average illite crystallite thickness (ICT) is smaller than 10 nm, and that RA matches these constraints for ICTs larger than 50 nm. We propose a new age correction method that takes into account the average ICT and corresponding recoiled 39Ar for a sample, with X-ray Corrected Ages (XCA) lying between Total-Gas and Retention Ages depending on ICT. This correction is particularly useful in samples containing authigenic illite formed in the anchizone, with typical ICT values between 10 and 50 nm. In three samples containing authigenic illite from Cretaceous carbonates in the Monterrey Salient in northern Mexico, there is a range in TGAs among the different size-fractions of 46-49, 36-43 and 40-52 Ma, while RAs range from 54-64, 47-52 and 53-54 Ma, respectively. XCA calculations produce tighter age ranges for these samples of 52.5-56, 45.5-48.5 and 49-52.5 Ma, respectively. In an apparent age vs ICT or %2M 1illite plot, authigenic illite grains show a slope that is in general slightly positive for TGA, slightly negative for RA, but close to zero for XCA, with thinner crystallites showing more dispersion than thicker ones. In order to test if dispersion is due to a different formation history or the result

The expansion of modern human populations in Africa 80,000 to 60,000 years ago and their initial exodus out of Africa have been tentatively linked to two phases of technological and behavioral innovation within the Middle Stone Age of southern Africa-the Still Bay and Howieson's Poort industries-that are associated with early evidence for symbols and personal ornaments. Establishing the correct sequence of events, however, has been hampered by inadequate chronologies. We report ages for nine sites from varied climatic and ecological zones across southern Africa that show that both industries were short-lived (5000 years or less), separated by about 7000 years, and coeval with genetic estimates of population expansion and exit times. Comparison with climatic records shows that these bursts of innovative behavior cannot be explained by environmental factors alone.

The purpose of this article is to present the treatment of a 8-year-old boy with tooth ankylosis in teeth 85 and Class II division 1 malocclusion and to report a 10-year follow-up result. The patient was initially treated with a sagittal removable appliance, followed by an eruption guidance appliance and braces. The interceptive orthodontic treatment performed to recover the space lost by ankylosis of a deciduous tooth allowed a spontaneous eruption and prevented progression of the problem. The use of an eruption-guidance appliance corrected the dentoskeletal Class II, thus improving the patient's appearance. Besides the treatment producing a good occlusal relationship with the Class I molar, the correction of the overjet and overbite was stable over a ten-year period.

The Late Career Nurse project examined views and characteristics of nurses working in New Zealand who were born before 1960. This paper focuses on the experiences of such nurses who undertake shift work. The mean age of registered nurses in New Zealand has been rising steadily, and 40% are now aged 50 years or over. While there is substantial literature on the phenomenon and consequences of the ageing nursing workforce, little is known of the particular experiences of nurses aged over 50 years who work shifts. An anonymous online survey was emailed to eligible nurse New Zealand Nurses Organisation members aged over 50 years in February 2012. Quantitative and qualitative analyses of the 3273 responses received were undertaken. Over 45% of respondents worked shifts or flexible hours. While shift work suited many, others noted deleterious effects on family and social relationships, physical and mental health (notably sleep patterns and fatigue), and decreasing tolerance for shift work as they age. Poor scheduling practices were particularly detrimental. Worldwide, workforce ageing means strategies are required to retain older nurses in the workforce. Improved scheduling practices including increasing access to flexible and part time work hours, and development of resources on coping with shift work are recommended. © 2013 John Wiley & Sons Ltd.

Taping is an effective temporary therapy for improving hallux valgus (HV) in adults. Although HV has been demonstrated to impair postural balance, there is a lack of information about how corrective taping affects balance and gait patterns in adults with HV deformity. Eighteen middle-aged female patients (average age, 53.5 years) with HV were included. Corrective tape was applied to correct HV angulation. A series of balance and gait stability tests were performed before applying tape and 1 hour after the tape was applied with a Balance Master computerized posturography device. The study involved the following tests: modified clinical test of sensory interaction and balance (mCTSIB), unilateral stance (US), limit of stability (LoS), step up/over (SUO), and walk across (WA) tests. No significant difference was found between the no-tape and taped condition in the static balance mCTSIB and US tests ( P > .05). The taping intervention resulted in significant improvement in the dynamic balance measures for the LoS test's backward reaction time and left maximum excursion ( P < .05), a significantly higher impact index bilaterally in the SUO assessment ( P < .05), and an increase in step width mean and variability in the WA test ( P < .05). Taping for correcting HV angulation had negative acute effects on dynamic balance in the SUO and WA tests and positive effects in the LoS test. Corrective taping, although a form of conservative treatment for hallux valgus, has been insufficiently studied in terms of effects on balance. Our results show that taping, as an acute effect, may impair balance in middle-aged adults when walking or ascending and descending stairs.

Objective To clarify if older pregnant women were more likely to have adverse perinatal outcomes when compared to women at an ideal age to have a child. Methods The groups were divided according to age groups: under 20 years, ≥20 to <40 years, and ≥40 years. Results During the period from January 1st, 2008, to December 31st, 2008, there were 76 births from patients younger than 20 years and 91 births from patients aged 40 years or over. To form a third group with intermediate age, the data of 92 patients aged 20 to 40 years were obtained, totaling 259 patients. Patients aged 40 or older had a statistically greater number of cesarean sections and less use of forceps or normal deliveries (p<0.001). The use of spinal anesthesia was statistically higher among those aged 40 years or more (p<0.001). The frequency of male newborns was statistically higher in older patients, a group with statistically fewer first pregnancies (p<0.001). The frequency of premature newborns was statistically higher in patients aged 40 years or more (p=0.004). Conclusion It is crucial to give priority to aged women, so that prenatal care will be appropriate, minimizing maternal complications and improving perinatal outcomes in this unique group.

The present study aimed to assess the prevalence of decreased visual acuity, strabismus, and spectacle wear in children aged 5 to 13 years. A cross-sectional study was performed in primary education schools. A total of 1938 participants, including 940 females (48.5%) and 998 males (51.5%) with a mean age 8.96 ± 2.31 (5-13 years old), were screened. The comparisons were performed with gender, age, and age groups. The children attended to vision screening were assigned to three age groups as 5-6 years, 7-9 years, and 10-13 years. The prevalence of the parameters was detected as decreased visual acuity 12.4%, strabismus 2.2%, and spectacle wear 6.9%. The prevalence of decreased visual acuity was significantly higher in girls and in children aged 7-9 years old (p = 0.013, p < 0.001). The prevalence of spectacle wear was significantly higher in girls and in children aged 7-9 years old (p = 0.019, p < 0.001). There was a visual acuity decrease in 33 of 106 (31.1%) children despite wearing own spectacle. There was no significant difference among three age groups for strabismus. Increased prevalence of decreased visual acuity, as well as the higher frequency of spectacle wear in children at ages of 7-9 years old may point out a threshold for visual impairment.

Artemisinin-based combination therapies are recommended as first-line treatments for uncomplicated falciparum malaria, but there is little evaluation of their efficacy and effects on uncomplicated malaria-associated anaemia in children aged 2 years and under. Parasitological efficacy and effects on malaria-associated anaemia were evaluated in 250 malarious children aged 2 years and under, and efficacy was evaluated in 603 malarious children older than two but younger than 5 years of age following treatment with artesunate-amodiaquine (AA) or artemether-lumefantrine (AL). Kinetics of the disposition of parasitaemia following treatment were evaluated using a non-compartment model. Late-appearing anaemia (LAA) was diagnosed using the following criteria: clearance of parasitaemia, fever and other symptoms occurring within 7 days of starting treatment, adequate clinical and parasitological response on days 28-42, haematocrit (HCT) ≥ 30 % at 1 and/or 2 weeks, a fall in HCT to < 30 % occurring at 3-6 weeks, absence of concomitant illness at 1-6 weeks, and absence of asexual parasitaemia detected using both microscopy and polymerase chain reaction (PCR) at 1-6 weeks. Overall, in children aged 2 years and under, the PCR-corrected parasitological efficacy was 97.2 % (95 % CI 92.8-101.6), which was similar for both treatments. In children older than 2 years, parasitological efficacy was also similar for both treatments, but parasite prevalence 1 day after treatment began was significantly higher, and fever and parasite clearance times were significantly faster in the AA-treated children compared with the AL-treated children. Declines in parasitaemia were monoexponential with an estimated elimination half-time of 1 h. Elimination half-times were similar for both treatments. In children aged 2 years and under who were anaemic at presentation, the mean anaemia recovery time was 12.1 days (95 % CI 10.6-13.6, n = 127), which was similar for both

The correction of severe post-tubercular kyphosis (PTK) is complex and has the disadvantage of being multiple staged with a high morbidity. Here, we describe the procedure and results of closing–opening osteotomy for correction of PTK which shortens the posterior column and opens the anterior column appropriately to correct the deformity without altering the length of the spinal cord. Seventeen patients with PTK (10 males; 7 females) with an average age of 18.3 ± 10.6 years (range 4–40 years) formed the study group. There were ten thoracolumbar, one lumbar and six thoracic deformities. The number of vertebrae involved ranged from 2 to 5 (average 2.8). Preoperative kyphosis averaged 69.2° ± 25.1° (range 42°–104°) which included ten patients with deformity greater than 60°. The average vertebral body loss was 2.01 ± 0.79 (range 1.1–4.1). The neurological status was normal in 13 patients, Frankel’s grade D in three patients and grade C in one. Posterior stabilization with pedicle screw instrumentation was followed by a preoperatively calculated wedge resection. Anterior column reconstruction was performed using rib grafts in four, tricortical iliac bone graft in five, cages in six, and bone chips alone and fibular graft in one patient each. Average operating time was 280 min (200–340 min) with an average blood loss of 820 ml (range 500–1,600 ml). The postoperative kyphosis averaged 32.4° ± 19.5° (range 8°–62°). The percentage correction of kyphosis achieved was 56.8 ± 14.6% (range 32–83%). No patient with normal preoperative neurological status showed deterioration in neurology after surgery. The last follow-up was at an average of 43 ± 4 months (range 32–64 months). The average loss of correction at the last follow-up was 5.4° (range 3°–9°). At the last follow-up, the mean preoperative pain visual analogue scale score decreased significantly from 9.2 (range 8–10 points) to 1.5 (range 1–2 points). There

Objectives: The aim of this study was to evaluate the proportion of completed treatments and to study the factors affecting the full mouth dental rehabilitation in pediatric patients treated by undergraduate students at the College of Dental Medicine Teaching Clinics, University of Sharjah. Materials and Methods: A retrospective study was conducted on 270 children aged less than 12 years (mean age 7.6, SD 2.04). Comprehensive dental rehabilitation reports of child patients that were completed by final year dental undergraduate students from the year 2009 to 2011 were reviewed. Data on complete history, oral examination, dental charting, and treatment plan were collected from pediatric dentistry case sheet. Dental caries was charted using WHO 1997 criteria. Dental treatment needs and completion of dental care delivered to children involved in this study were assessed using DMFT/deft scores. Results: Percentages of treatment provided included completed restorations (94%) and space management (84%) in primary dentition, whereas 98% of restoration and 94% of required sealants were completed in permanent dentition. The percentage of completed dental treatment including sealant placement was 61%. Age of the child and the number of decayed teeth present before the start of the treatment significantly correlated with the children in the incomplete treatment category (P < 0.05). Conclusions: Therefore, a worthy dental care was provided in a holistic approach to the children attending College of Dental Medicine training clinics. Age of the child and the number of decayed teeth were the factors affecting dental rehabilitation in children aged 3–12 years. PMID:26236683

Accurate determination of age is of fundamental importance to population and life history studies of waterfowl and their management. Therefore, we developed quantitative methods that separate adult and immature blue-winged teal (Anas discors), cinnamon teal (A. cyanoptera), and northern shovelers (A. clypeata) during spring and summer. To assess suitability of discriminant models using 9 remigial measurements, we compared model performance (% agreement between predicted age and age assigned to birds on the basis of definitive cloacal or rectral feather characteristics) in different flyways (Mississippi and Pacific) and between years (1990-91 and 1991-92). We also applied age-classification models to wings obtained from U.S. Fish and Wildlife Service harvest surveys in the Mississippi and Central-Pacific flyways (wing-bees) for which age had been determined using qualitative characteristics (i.e., remigial markings, shape, or wear). Except for male northern shovelers, models correctly aged lt 90% (range 70-86%) of blue-winged ducks. Model performance varied among species and differed between sexes and years. Proportions of individuals that were correctly aged were greater for males (range 63-86%) than females (range 39-69%). Models for northern shovelers performed better in flyway comparisons within year (1991-92, La. model applied to Calif. birds, and Calif. model applied to La. birds: 90 and 94% for M, and 89 and 76% for F, respectively) than in annual comparisons within the Mississippi Flyway (1991-92 model applied to 1990-91 data: 79% for M, 50% for F). Exclusion of measurements that varied by flyway or year did not improve model performance. Quantitative methods appear to be of limited value for age separation of female blue-winged ducks. Close agreement between predicted age and age assigned to wings from the wing-bees suggests that qualitative and quantitative methods may be equally accurate for age separation of male blue-winged ducks. We interpret annual

The 14C reservoir age of the surface ocean was determined for two Holocene periods (4908-4955 and 3008-3066 calendar (cal) B.P.) using U/Th-dated corals from Biscayne National Park, Florida, United States. We found that the average reservoir ages for these two time periods (294 ?? 33 and 291 ?? 27 years, respectively) were lower than the average value between A.D. 1600 and 1900 (390 ?? 60 years) from corals. It appears that the surface ocean was closer to isotopic equilibrium with CO2 in the atmosphere during these two time periods than it was during recent times. Seasonal ??18O measurements from the younger coral are similar to modern values, suggesting that mixing with open ocean waters was indeed occurring during this coral's lifetime. Likely explanations for the lower reservoir age include increased stratification of the surface ocean or increased ??14C values of subsurface waters that mix into the surface. Our results imply that a more correct reservoir age correction for radiocarbon measurements of marine samples in this location from the time periods ???3040 and ???4930 cal years B.P. is ???292 ?? 30 years, less than the canonical value of 404 ?? 20 years.

The U.S. NHANES included chemosensory assessments in the 2011–2014 protocol. We provide an overview of this protocol and 2012 olfactory exam findings. Of the 1818 NHANES participants aged ≥40 years, 1281 (70.5 %) completed the exam; non-participation mostly was due to time constraints. Health technicians administered an 8-item, forced-choice, odor identification task scored as normosmic (6–8 odors identified correctly) versus olfactory dysfunction, including hyposmic (4–5 correct) and anosmic/severe hyposmic (0–3 correct). Interviewers recorded self-reported smell alterations (during past year, since age 25, phantosmia), histories of sinonasal problems, xerostomia, dental extractions, head or facial trauma, and chemosensory-related treatment and changes in quality of life. Olfactory dysfunction was found in 12.4 % (13.3 million adults; 55 % males/45 % females) including 3.2 % anosmic/severe hyposmic (3.4 million; 74 % males/26 % females). Selected age-specific prevalences were 4.2 % (40–49 years), 12.7 % (60–69 years), and 39.4 % (80+ years). Among adults ≥70 years, misidentification rates for warning odors were 20.3 % for smoke and 31.3 % for natural gas. The highest sensitivity (correctly identifying dysfunction) and specificity (correctly identifying normosmia) of self-reported olfactory alteration was among anosmics/severe hyposmics (54.4 % and 78.1 %, respectively). In age- and sex-adjusted logistic regression analysis, risk factors of olfactory dysfunction were racial/ethnic minority, income-to-poverty ratio ≤ 1.1, education year, since age 25, phantosmia) could screen for marked dysfunction. Healthcare providers should be prepared to offer education on non-olfactory avoidance of

The purpose of this study was to establish normative reference values for spatiotemporal and plantar pressure parameters, and to investigate the influence of demographic, anthropometric and physical characteristics. In 1000 healthy males and females aged 3-101 years, spatiotemporal and plantar pressure data were collected barefoot with the Zeno™ walkway and Emed ® platform. Correlograms were developed to visualise the relationships between widely reported spatiotemporal and pressure variables with demographic (age, gender), anthropometric (height, mass, waist circumference) and physical characteristics (ankle strength, ankle range of motion, vibration perception) in children aged 3-9 years, adolescents aged 10-19 years, adults aged 20-59 years and older adults aged over 60 years. A comprehensive catalogue of 31 spatiotemporal and pressure variables were generated from 1000 healthy individuals. The key findings were that gait velocity was stable during adolescence and adulthood, while children and older adults walked at a comparable slower speed. Peak pressures increased during childhood to older adulthood. Children demonstrated highest peak pressures beneath the rearfoot whilst adolescents, adults and older adults demonstrated highest pressures at the forefoot. Main factors influencing spatiotemporal and pressure parameters were: increased age, height, body mass and waist circumference, as well as ankle dorsiflexion and plantarflexion strength. This study has established whole of life normative reference values of widely used spatiotemporal and plantar pressure parameters, and revealed changes to be expected across the lifespan.

Foetal growth restriction (FGR) is associated with communication problems, which might lead to poor literacy skills. The reading and spelling skills of eight- to 10-year-old FGR children born at 24-40 gestational weeks were compared with those of their gestational age-matched, appropriately grown (AGA) peers. A prospectively collected cohort of 37 FGR and 31 AGA children was recruited prenatally at a Finnish tertiary care centre during 1998-2001. The children's reading and spelling skills were assessed using standardised tests for Finnish-speaking second and third graders. Significantly more children performed below the 10th percentile normal values for reading and spelling skills in the FGR group than in the AGA group. At nine years of age, the FGR children had significantly poorer performance in word reading skills and reading fluency, reading accuracy and reading comprehension than the AGA controls. No between-group differences were detected at eight years of age. FGR is associated with poor performance in reading and spelling skills. A third of the FGR children performed below the 10th percentile normal values at nine years of age. These results indicate a need to continuously evaluate linguistic and literacy skills as FGR children age to ensure optimal support. ©2017 Foundation Acta Paediatrica.

Between August 1989 and July 2003 14 Jehovah's Witness children with congenital heart defects (CHD) aged under 14 years (median 2.9 years) and with a median weight of 14 kg underwent 16 operations with cardiopulmonary bypass (CPB). Five children had been operated on previously between one to three times. Preoperatively, 7 children were prepared with oral iron supplementation and 10 received erythropoietin. Mean hemoglobin (Hb) at admission was 14.4 g/dl (range 10.9 - 19.2). The cardiopulmonary bypass (CPB) circuit was modified to reduce total priming volume. High doses of aprotinin were administered. The modified ultrafiltration (MUF) circuit, used in 7 patients, was parallel to the ECC circuit with continuous circulation of the blood through a small shunt between the arterial and venous lines. Operations performed consisted of VSD closure (3 pts.), ASD closure (3 pts.), Fontan operation (2 pts.), and complete AV canal correction, aortic commissurotomy, Ross operation, Glenn shunt, cor triatriatum correction, MV reconstruction combined with left outflow tract stenosis resection, correction of absent pulmonary valve syndrome, and correction of tetralogy of Fallot in one patient each. There were no deaths. Mean duration of CPB was 192 min and mean aortic cross-clamp time 40 min. The Hb value at the end of the operation was 4.9 - 14.5 g/dl (mean 9.6) and at discharge it was 7.1 - 14.5 g/dl (mean 15.5). No blood or blood products were used in any patient. Bloodless cardiac surgery with and without CPB can be safely performed in Jehovah's Witness infants and children.

Objective We aimed to study the association between neighborhood socioeconomic status at the age of 40 years and risk of ischemic stroke before the age of 50 years. Methods All individuals in Sweden were included if their 40th birthday occurred between 1998 and 2010. National registers were used to categorize neighborhood socioeconomic status into high, middle, and low and to retrieve information on incident ischemic strokes. Hazard ratios and their 95% confidence intervals were estimated. Results A total of 1,153,451 adults (women 48.9%) were followed for a mean of 5.5 years (SD 3.5 years), during which 1777 (0.30%) strokes among men and 1374 (0.24%) strokes among women were recorded. After adjustment for sex, marital status, education level, immigrant status, region of residence, and neighborhood services, there was a lower risk of stroke in residents from high-socioeconomic status neighborhoods (hazard ratio 0.87, 95% confidence interval 0.78-0.96), and an increased risk of stroke in adults from low-socioeconomic status neighborhoods (hazard ratio 1.16, 95% confidence interval 1.06-1.27), compared to their counterparts living in middle-socioeconomic status neighborhoods. After further adjustment for hospital diagnoses of hypertension, diabetes, heart failure, and atrial fibrillation prior to the age of 40, the higher risk in neighborhoods with low socioeconomic status was attenuated, but remained significant (hazard ratio 1.12, 95% confidence interval 1.02-1.23). Conclusions In a nationwide study of individuals between 40 and 50 years, we found that the risk of ischemic stroke differed depending on neighborhood socioeconomic status, which calls for increased efforts to prevent cardiovascular diseases in low socioeconomic status neighborhoods.

To investigate the clinical utility of the reverse gradient algorithm in correcting distortions in diffusion-weighted images of the cervix and for increasing diagnostic performance. Forty-one patients ages 25-72 years (mean 40 ± 11 years) with suspected or early stage cervical cancer were imaged at 3T using an endovaginal coil. T2 -weighted (W) and diffusion-weighted images with right and left phase-encode gradient directions were obtained coronal to the cervix (b = 0, 100, 300, 500, 800 s mm(-2) ). Differences in angle of the endocervical canal to the x-axis between T2 W and right-gradient, left-gradient, and corrected images were measured. Uncorrected and corrected images were assessed for diagnostic performance when viewed together with T2 W images by two independent observers against subsequent histology. The angles of the endocervical canal relative to the x-axis were significantly different between the T2 W images and the right-gradient images (P = 0.007), approached significance for left-gradient images (P = 0.055), and were not significantly different after correction (P = 0.95). Corrected images enabled a definitive diagnosis in 34% (n = 14) of patients classified as equivocal on uncorrected images. Tumor volume in this subset was 0.18 ± 0.44 cm(3) (mean ± SD; sensitivity of detection 100% [8/8], specificity 50% [3/6] for an experienced observer). Correction did not improve diagnostic performance for the less-experienced observer. Distortion-corrected diffusion-weighted images improved correspondence with T2 W images and diagnostic performance in a third of cases. © 2015 The Authors Journal of Magnetic Resonance Imaging published by Wiley Periodicals, Inc. on behalf of International Society for Magnetic Resonance in Medicine.

The goal of this study was to identify the frequency of physician-diagnosed food allergies among 6-year-old US children and study the impact of exclusive breastfeeding and complementary food introduction on this frequency. Data were analyzed from children who participated in the Infant Feeding Practices Study II Year 6 Follow-Up Study (Y6FU). Children with probable food allergy (pFA) were defined as children with report of physician-diagnosed food allergy at age 6 years. Subgroups of pFA included children who were not diagnosed before 1 year of age (new pFA) and those with atopic risk factors (high risk). Prevalence of total pFA in the Y6FU was 6.34%. The majority of these children had new pFA and high-risk factors. Higher maternal education, higher family income, family history of food allergy, and reported eczema before 1 year of age were significantly associated with higher odds of total or new pFA. Exclusive breastfeeding duration and timing of complementary food introduction were not significantly associated with total pFA. However, exclusive breastfeeding of ≥4 months compared with no breastfeeding was marginally associated with lower odds of new pFA (adjusted odds ratio: 0.51; P = .07); this effect was not observed with high-risk children. Analysis of infant and maternal variables in the Y6FU cohort of US children revealed that socioeconomic and atopic factors were the main predictors of pFA at age 6 years. Exclusive breastfeeding of ≥4 months may have a preventive effect on development of pFA after 1 year of age in non high-risk children. Copyright © 2014 by the American Academy of Pediatrics.

There is uncertainty in the published literature as to whether physical activity should be advocated for age-related macular degeneration (AMD) prevention. We aimed to assess prospectively the association between physical activity and the 15-year incidence of AMD in older adults. We assessed AMD from retinal photographs. Participants provided details of walking exercise and the performance of moderate or vigorous activities, which were used to calculate metabolic equivalents (METs). After adjusting for age, adults aged ≥ 75 years in the highest tertile (the most physically active) compared to those in the lowest tertile (least physically active) were 79% less likely to have incident late AMD over the 15 years (odds ratio [OR], 0.21; 95% confidence intervals [CI], 0.05-0.95). However, after further adjusting for sex, body mass index, smoking, fish consumption, and white cell count, this association was no longer statistically significant (OR, 0.26; 95% CI, 0.06-1.28). Significant associations were not found in those aged <75 or with the 15-year cumulative incidence of early AMD. Physical activity did not influence the risk of AMD over 15 years in older adults, independent of diet, smoking, white cell count, and body mass index.

Objective: The present study aimed to assess the prevalence of decreased visual acuity, strabismus, and spectacle wear in children aged 5 to 13 years. Methods: A cross-sectional study was performed in primary education schools. A total of 1938 participants, including 940 females (48.5%) and 998 males (51.5%) with a mean age 8.96 ± 2.31 (5-13 years old), were screened. The comparisons were performed with gender, age, and age groups. The children attended to vision screening were assigned to three age groups as 5-6 years, 7-9 years, and 10-13 years. Results: The prevalence of the parameters was detected as decreased visual acuity 12.4%, strabismus 2.2%, and spectacle wear 6.9%. The prevalence of decreased visual acuity was significantly higher in girls and in children aged 7-9 years old (p = 0.013, p < 0.001). The prevalence of spectacle wear was significantly higher in girls and in children aged 7-9 years old (p = 0.019, p < 0.001). There was a visual acuity decrease in 33 of 106 (31.1%) children despite wearing own spectacle. There was no significant difference among three age groups for strabismus. Conclusion: Increased prevalence of decreased visual acuity, as well as the higher frequency of spectacle wear in children at ages of 7-9 years old may point out a threshold for visual impairment.

To determine through the measurement of different angles the correction of lumbar hyperlordosis after bilateral femoral lengthening using the Icatme technique and to assess the absence of neurological symptomatology secondary to stenosis of the lumbar canal after femoral lengthening. Thirty-four patients with achondroplasia were studied. Mean age was 22.3 years. The patients underwent femoral lengthening using the Icatme technique. X rays of the lateral rachis taken before and after lengthening were used to measure a series of angles. The lumbar lordosis angle, Sez's angle and the L5S1 angle decreased while the lumbosacral angle, Jungham's angle and the sacrum angle increased, leading to correction of lumbar hyperlordosis, verticalization of the sacrum and improvement in thoracolumbar and lumbosacral inflection. Values were similar to the standard for individuals without achondroplasia. Femoral lengthening using the Icatme technique in achondroplastics modifies the statics of the lumbar spine, making them similar to those of nonachondroplastics. The procedure corrects lumbar hyperlordosis and prevents the appearance of neurological symptomatology due to stenosis of the lumbar canal. The incidence of neurological complications due to stenosis of the lumbar canal in achondroplastics who have undergone femoral lengthening is low compared with that of achondroplastics of the same age and sex who have not undergone this procedure.

This study investigated whether parenting behaviors differed between parents of 68 clinically anxious children and 106 healthy control children aged 4-12 years. The effects of parent gender, child gender and child age on parenting were explored. Mothers and fathers completed a questionnaire to assess parenting behaviors in for children hypothetically anxious situations. Results showed that parents of clinically anxious children reported more anxiety-enhancing parenting (reinforcement of dependency and punishment) as well as more positive parenting (positive reinforcement). For the clinical sample, fathers reported using more modeling/reassurance than mothers, and parents reported using more force with their 4-7-year-olds than with their 8-12-year-olds. No interaction effects were found for child gender with child anxiety status on parenting. Results indicate that for intervention, it is important to measure parenting behaviors, and to take into account father and mother differences and the age of the child. Copyright © 2015 Elsevier Ltd.

Little is known about the secular trends in age at spermarche among boys, and the association between body mass index (BMI) and male puberty is controversial. This study aimed to estimate the trend in age at spermarche in China and explore the association of spermarche with BMI. We used four cross-sectional Chinese National Surveys on Students' Constitution and Health (CNSSCH; 1995, 2000, 2005 and 2010). Median age at spermarche was determined using probit analysis. Logistic regression was used to assess the association of spermarche with BMI. Age at spermarche among Chinese boys dropped from 14.57 to 14.03 years from 1995 to 2010 with a decrease of 4.3 months per decade. Boys with BMI-for-age z-score lower than -2 had the latest age at spermarche. A higher BMI or BMI-for-age z-score was associated with an increased likelihood of having reached spermarche, and this association was consistently observed at all survey points. This study provides important evidence of a secular trend of earlier age at spermarche over the past 15 years in China, and this decrease was accompanied by a simultaneous increase in BMI. Strategies and interventions focusing on thinness may promote both their nutritional status and puberty development among Chinese boys. © 2015 World Obesity.

Background: There is increasing concern about the potential effects of traffic-related air pollution (TRAP) on the developing brain. The impact of TRAP exposure on childhood behavior is not fully understood because of limited epidemiologic studies. Objective: We explored the association between early-life exposure to TRAP using a surrogate, elemental carbon attributed to traffic (ECAT), and attention deficit/hyperactivity disorder (ADHD) symptoms at 7 years of age. Methods: From the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) birth cohort we collected data on exposure to ECAT during infancy and behavioral scores at 7 years of age. Children enrolled in CCAAPS had at least one atopic parent and a birth residence either < 400 m or > 1,500 m from a major highway. Children were followed from infancy through 7 years of age. ECAT exposure during the first year of life was estimated based on measurements from 27 air sampling sites and land use regression modeling. Parents completed the Behavioral Assessment System for Children, 2nd Edition, when the child was 7 years of age. ADHD-related symptoms were assessed using the Hyperactivity, Attention Problems, Aggression, Conduct Problems, and Atypicality subscales. Results: Exposure to the highest tertile of ECAT during the child’s first year of life was significantly associated with Hyperactivity T-scores in the “at risk” range at 7 years of age, after adjustment [adjusted odds ratio (aOR) = 1.7; 95% CI: 1.0, 2.7]. Stratification by maternal education revealed a stronger association in children whose mothers had higher education (aOR = 2.3; 95% CI: 1.3, 4.1). Conclusions: ECAT exposure during infancy was associated with higher Hyperactivity scores in children; this association was limited to children whose mothers had more than a high school education.

There is a well-known link between attending college and engaging in excessive alcohol use. This study examines in a national sample how the association between student status and excessive alcohol use changes from late adolescence through young adulthood and whether the association of student status with excessive alcohol use is different for students residing with versus away from parents during the school year. This study used cross-sectional data from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of noninstitutionalized civilian adults residing in the United States. Our analyses included nonhigh school young adults who were ages 18 to 30 years (n = 8,645). Excessive alcohol use included past-year (i) high-intensity drinking (men: ≥10 standard drinks; women: ≥8) and (ii) exceeding weekly drinking guidelines (men: >14 drinks per week; women: >7). Students who resided away from their parents and students who lived with their parents during the school year were compared to nonstudents. Analyses using time-varying effect modeling showed that the relationship of student status with excessive alcohol use varied as a function of age. Overall student status lost its association with excessive alcohol use in the early 20s, after controlling for demographics and other adult social roles. The association between student status and excessive alcohol use also varied considerably across age and depending on whether the student was residing with or away from parents. The association of student status with excessive alcohol use is heterogeneous in terms of both age and living arrangements, suggesting opportunities for interventions targeting problematic alcohol use. Future research should examine additional sources of heterogeneity of students in their risk for excessive alcohol use. Copyright © 2016 by the Research Society on Alcoholism.

This study was conducted to assess the impact of administration of two-dose rotavirus (RV) vaccine (RIX4414; GlaxoSmithKline Vaccines) among children aged less than 5 y in three states/territories of Australia. Aggregated and de-identified data on rotavirus gastroenteritis (RVGE) and all-cause gastroenteritis (AGE) from July 1998–June 2009 were obtained from the Australian Institute of Health and Welfare database. The baseline incidence (July 1998–June 2006) of RVGE hospitalizations before RV vaccine introduction in New South Wales (NSW), the Australian Capital Territory (ACT) and the Northern Territory (NT) were 33.75, 42.93 and 288.67 per 10 000 child-years, respectively among children aged 0–11 mo. Following RV vaccine introduction in NSW, the ACT and the NT, incidence of RVGE hospitalizations reduced to 13.06, 17.35 and 47.52 per 10 000 child-years, respectively, during July 2007–June 2008 and 3.87, 8.40 and 122.79 per 10,000 child-years, respectively, during July 2008–June 2009 among children aged 0–11 mo. Reductions in RVGE and AGE were also observed in all children below 5 y of age in NSW and the ACT. Overall reduction in hospitalizations due to RVGE and AGE was observed following RV vaccine introduction into the NIP in Australia. PMID:23733041

Suicide and injury mortality data, plus mortality data from all causes, were used to compare the trend lines. Suicide mortality rate in young people aged 15-19 years and in all population showed a rising trend from 1990, and then a decreasing trend from 2002 year. This trend was significant exclusively in boys. When comparing suicide deaths as a percentage of injury deaths and of all deaths in the age group 15-19 years, rising trends for boys were evident, whilst in girls, there was no evidence of change. In Lithuania, from early 1990s, the frequency of suicide increased amongst adults and young people aged 15-19 years. After 2002, a decrease in deaths by suicide was observed both for the whole population and for young people aged 15-19 years. The rise and fall was obvious for boys. The reasons for different trends may have been influenced by the political and socioeconomic instability in the 1990-2002 period, and the socioeconomic stability, together with active preventive measures, from 2002. Although the consumption of modern Selective serotonin reuptake inhibitors (SSRIs) increased during the same time, suicide mortality was again high during the economic crisis in 2008-2009. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

To determine whether Bayley Scales of Infant and Toddler Development (3rd edition) (Bayley-III) motor scores and neurological examination at 2 years corrected age predict motor difficulties at 4.5 years corrected age. A prospective cohort study of children born at risk of neonatal hypoglycaemia in Waikato Hospital, Hamilton, New Zealand. Assessment at 2 years was performed using the Bayley-III motor scale and neurological examination, and at 4.5 years using the Movement Assessment Battery for Children (2nd edition) (MABC-2). Of 333 children, 8 (2%) had Bayley-III motor scores below 85, and 50 (15%) had minor deficits on neurological assessment at 2 years; 89 (27%) scored less than or equal to the 15th centile, and 54 (16%) less than or equal to the 5th centile on MABC-2 at 4.5 years. Motor score, fine and gross motor subtest scores, and neurological assessments at 2 years were poorly predictive of motor difficulties at 4.5 years, explaining 0 to 7% of variance in MABC-2 scores. A Bayley-III motor score below 85 predicted MABC-2 scores less than or equal to the 15th centile with a positive predictive value of 30% and a negative predictive value of 74% (7% sensitivity and 94% specificity). Bayley-III motor scale and neurological examination at 2 years were poorly predictive of motor difficulties at 4.5 years. © 2016 Mac Keith Press.
