Abstract:
Abstract Among 2,038 older Chinese adults in the U.S., we examined the relationship between physical function (Short Performance Physical Battery [SPPB], [instrumental] activities of daily living [ADL/IADL] limitations) at baseline (2011-2013) and changes in cognitive function in the two-year follow-up (2013-2015). Cognitive function was measured by the East Boston Memory Test (EBMT), the Digit Span Backwards assessment (DSB), the Symbol Digit Modalities Test (SDMT), and the Mini-Mental State Examination (MMSE). During the two-year follow-up, 41.8%-50.88% of the participants decreased in cognitive function and 32.88%-44.8% increased. In linear regression that adjusted for baseline cognitive function, education, age, and other covariates, baseline SPPB and ADL/IADL limitations were significantly associated with changes in cognitive function in the two-year follow-up (SPPB: βEBMT=0.0149, p<0.05; βDSB=0.0253, p>0.05; βSDMT=0.2742, p<0.01; βMMSE=0.1070, p<0.001; ADL/IADL limitations: βEBMT= -0.0401, p<0.0001; βDSB= -0.0410, p<0.05; βSDMT= -0.3027, p<0.01; βMMSE= -0.2566, p<0.0001). This suggests that better physical function predicts positive changes in cognitive function.

Abstract:
BACKGROUND: In children with hypoplasia or aplasia of the radius (radial longitudinal deficiency) manual activity limitations may be caused by several factors; a short and bowed forearm, radial deviation of the wrist, a non-functional or absent thumb, limited range of motion in the fingers and impaired grip strength. The present study investigates the relation between these variables and activity and participation in children with radial dysplasia. METHODS: Twenty children, age 4-17 years, with radial longitudinal dysplasia Bayne type II-IV were examined with focus on the International Classification of Functioning and Health, version for Children and Youth (ICF-CY) context. Body function/structure was evaluated by measures of range of motion, grip strength, sensibility and radiographic parameters. Activity was examined by Box and Block Test and Assisting Hand Assessment (AHA). Participation was assessed by Children's Hand-use Experience Questionnaire (CHEQ). Statistical correlations between assessments of body function/structure and activity as well as participation were examined. RESULTS: The mean total active motion of wrist (49.6°) and digits (447°) were less than norms. The mean hand forearm angle was 34° radially. Ulnar length ranged from 40 to 80% of age-related norms. Grip strength (mean 2.7 kg) and Box and Block Test (mean 33.8 blocks/minute) were considerably lower than for age-related norms. The mean score for the AHA was 55.9 and for CHEQ Grasp efficiency 69.3. The AHA had significant relationship with the total range of motion of digits (p = 0.042). Self-experienced time of performance (CHEQ Time) had significant relationship with total active motion of wrist (p = 0.043). Hand forearm angle did not show any significant relationship with Box and Block Test, AHA or CHEQ. CONCLUSION: In radial longitudinal deficiency total range of motion of digits and wrist may be of more cardinal importance to the child's activity and participation than the angulation of the wrist.

Abstract:
Objectives: To determine the association of systolic blood pressure (SBP) and medication to renal function over time in a cohort of hypertensive veterans. Three research questions were addressed. What is the relationship between GFR and SBP in all veterans? In normotensive veterans, what is the relationship between developing hypertension and GFR? In veterans with a hypertension diagnosis, what is the relationship between controlled SBP, anti-hypertensive medications and GFR? Methods: Data were obtained from Southern Arizona Veterans' Affairs Health Care System from January 1, 2000 through December 31, 2006. Inclusion criteria consisted of veterans ≥ 21 and < 90 years of age with at least two SBP measurements and two serum creatinine measurements at least 90 days apart. Analyses were performed using a generalized linear mixed model to address serial correlation. Blood pressure, age, sex, race/ethnicity membership, diabetes, proteinuria, and risk factors for renal failure were examined. First, all eligible veterans’ GFR was modeled over seven years. Second, an inception cohort was formed with veterans who developed hypertension over the study period. Third, veterans with a hypertension ICD-9 formed time-varying controlled/uncontrolled hypertension groups. Medication categories examined in the hypertension groups included angiotensin converting enzyme inhibitor(ACE), betablocker( BB), calcium channel blocker(CCB) monotherapy, or combinations of ACE, BB, and CCB. Results: A total of 39,948 veterans were eligible for the first analysis. There were 3,036 who developed hypertension compared to 8,856 who did not in the second analysis. The third analysis consisted of 25,819 subjects: 12,411 with controlled, 13,406 with uncontrolled SBP. In each analysis, there were first-order interactions between blood pressure*age, and blood pressure*time, making interpretation of the results dependant upon these variables. Overall, GFR decreased over time, increasing blood pressure, and increasing age. ACE, BB, CCB use was associated with higher GFR (1.7, 95% CI 1.4-2.1; 1.0, 95% CI 0.7-1.4; and 0.8, 95% CI 0.3-1.3 ml/minute/1.73m², respectively). Conclusions: These analyses identified significant decrease in GFR over time. The effect of blood pressure on GFR was dependent upon time and age. Persons with controlled BP taking antihypertensive therapy had higher GFR than those taking no medication suggesting that antihypertensive medication use preserves kidney function.

Abstract:
Three longitudinal pulmonary function data sets were analyzed by several statistical methods for the purposes of: 1) determining to what degree the conclusions of an analysis for a given data set are method dependent; 2) assessing the properties of each method across the different data sets; 3) studying the correlates of FEV₁ decline including physical, behavioral, and respiratory factors, as well as city of residence and type of work. 4) assessing the appropriateness of modelling the standard linear relationship of FEV₁ with time and providing alternative approaches; 5) describing longitudinal change in various lung function variables, apart from FEV₁. The three data sets were comprised of (1) yearly data on 141 veterans with mild chronic bronchitis, taken at three Canadian centres, for a maximum of 23 years of follow-up; their mean age at the start of the study was 49 years (s.d.=9) and only 10.6% were nonsmokers during the follow-up; (2) retrospective data on 384 coal workers categorized into four groups according to vital status (dead or alive) and smoking behavior, with irregular follow-up intervals ranging from 2 to 12 measurements per individual over a period of 9 to 30 years; (3) a relatively balanced data set on 269 grain workers and a control group of 58 civic workers, which consisted of 3 to 4 measurements taken over an average follow-up of 9 years. Their mean age at first measurement was 37 years (s.d.=10) and 53.2% of the subjects did not smoke. A review of the pulmonary and statistical literature was carried out to identify methods of analysis which had been applied to calculate annual change in FEV₁. Five methods chosen for the data analyses were variants of ordinary least squares approaches. The other four methods were based on the use of transformations, weighted least squares, or covariance structure models using generalized least squares approaches. For the coal workers, the groups that were alive at the time of ascertainment had significantly smaller average FEV₁ declines than the deceased groups. Post-retirement decline in FEV₁ was shown by one statistical method to significantly increase for coal workers who smoked, while a significant decrease was observed for nonsmokers. Veterans from Winnipeg consistently showed the lowest decline estimates in comparison to Halifax and Toronto; recorded air pollution measurements were found to be the lowest for Winnipeg, while no significant differences in smoking behavior were found between the veterans of each city. The data set of grain workers proved most ameniable to all the different analytical techniques, which were consistent in showing no significant differences in FEV₁ decline between the grain and civic workers groups and the lowest magnitude of FEV₁ decline. It was shown that quadratic and allometric analyses provided additional information to the linear description of FEV₁ decline, particularly for the study of pulmonary decline among older or exposed populations over an extended period of time. Whether the various initial lung function variables were each predictive of later decline was dependent on whether absolute or percentage decline was evaluated. The pattern of change in these lung function measures over time showed group differences suggestive of different physiological responses. Although estimates of FEV₁ decline were similar between the various methods, the magnitude and relative order of the different groups and the statistical significance of the observed inter-group comparisons were method-dependent No single method was optimal for analysis of all three data sets. The reliance on only one model, and one type of lung function measurement to describe the data, as is commonly found in the pulmonary literature, could lead to a false interpretation of the result Thus a comparative approach, using more than one justifiable model for analysis is recommended, especially in the usual circumstances where missing data or irregular follow-up times create imbalance in the longitudinal data set.

Abstract:
Improving the estimation efficiency has always been one of the important aspects in statistical modelling. Our goal is to develop new statistical methodologies yielding more efficient estimators in the analysis of longitudinal data. In this thesis, we consider two different approaches, empirical likelihood and jointly modelling the mean and variance, to improve the estimation efficiency. In part I of this thesis, empirical likelihood-based inference for longitudinal data within the framework of generalized linear model is investigated. The proposed procedure takes into account the within-subject correlation without involving direct estimation of nuisance parameters in the correlation matrix and retains optimality even if the working correlation structure is misspecified. The proposed approach yields more efficient estimators than conventional generalized estimating equations and achieves the same asymptotic variance as quadratic inference functions based methods. The second part of this thesis focus on the joint mean-variance models. We proposed a data-driven approach to modelling the mean and variance simultaneously, yielding more efficient estimates of the mean regression parameters than the conventional generalized estimating equations approach even if the within-subject correlation structure is misspecified in our joint mean-variance models. The joint mean-variances in parametric form as well as semi-parametric form has been investigated. Extensive simulation studies are conducted to assess the performance of our proposed approaches. Three longitudinal data sets, Ohio Children’s wheeze status data (Ware et al., 1984), Cattle data (Kenward, 1987) and CD4+ data (Kaslowet al., 1987), are used to demonstrate our models and approaches.

Full text
Abstract:
Cognitive deficits are a well recognised feature of schizophrenia, with patients showing disproportionate impairments in aspects of memory and executive function. Atypical antipsychotics have shown some success at remediating these deficits which suggests that the basis of the cognitive impairment might be neurochemical in origin. However, the precise nature of this effect is unknown. Mechanisms of action might involve antagonism of 5 HT-2A receptors which results in increased prefrontal dopamine, or the affinity of these medications to dopamine receptors or multiple receptors. Patients with a diagnosis of schizophrenia were recruited for the study within 6 weeks of starting one of the atypical antipsychotics; clozapine, olanzapine, risperidone, quetiapine & amisulpride. They were assessed on clinical variables and a wide battery of cognitive tests at baseline, 9-month-follow-up and 18-month-follow-up. For the analysis the whole group was split into different subgroups according to the neurochemical properties of the individual antipsychotics; • Those with a high affinity for 5HT-2A receptors (risperidone, olanzapine & c1ozapine) vs. those with a low affinity for these receptors (quetiapine & amisutpride). • Those with a preferential affinity for dopamine receptors (risperidone & amisulpride) vs.those with an affinity for multiple receptors (otanzapine, clozapine & quetiapine). • Those with a fast dissociation from the 02 receptor (c1ozapine, quetiapine & amisulpride) vs. those with a slower dissociation from this receptor (olanzapine & risperidone) • In addition the individual medication groups were compared on all measures The main findings were that medications that had a high affinity for 5-HT2A receptors exerted negative effects on some aspects of cognition, whilst those with a low affinity for 5HT-2A receptors exerted beneficial effects. In addition, the individual atypical antipsychotics differed in their cognitive effects. It is concluded that affinity to 5HT-2A receptors is an important determinant of the cognitive response to atypical antipsychotics.

Full text
Abstract:
Extending the storage time of nuclear spin order is an important issue in modern NMR spectroscopy since many NMR and MRI applications are limited by the lifetime of spin states. Under normal circumstances the survival of spin magnetization is limited by longitudinal relaxation (T1) which brings the magnetization back to equilibrium within a few seconds. The conversion of longitudinal into singlet order can extend that lifetime to tens of minutes up to an hour. Most nuclear spin relaxation mechanisms in liquids are a function of the correlation time τc of the molecule, which is linked to the molecular tumbling, and inversely proportional to viscosity. Therefore a lower viscosity would reduce the influence of those mechanisms. The increase in the lifetime of longitudinal (T1) and singlet order (TS) is shown here as the viscosity of common organic solvents decreases. The study includes measurements in liquid and supercritical CO2, that oer an extremely low viscosity regime. The further extension of spin order lifetimes for a singlet bearing molecule in liquid CO2 is presented. There appears to be an upper limit to the extension of the singlet order lifetime that is caused by relaxation mechanisms acting in different directions.

Abstract:
On free propagation the cross-spectral density function obeys two Helmholtz equations. We show that under the paraxial approximation, both equations can conveniently be written as a single differential equation in terms of the sum and difference coordinates. Furthermore, we indicate that the formal solution to this single differential equation can be written as a differential operator, which converts the cross-spectral density function at the object plane into the cross-spectral density function at any other plane. This formalism is applied to give a coherence theory of the Lau effect at finite distances when using quasihomogeneous fields.

Abstract:
The learning and developmental losses from pre-primary program closures due to COVID-19 may be unprecedented. These disruptions early in life, when the brain is more sensitive to environmental changes, can be long-lasting. Although there is evidence about the effects of school closures on older children, there is currently no evidence on such losses for children in their early years. This paper is among the first to quantify the actual impact of pandemic-related closures on child development, in this case for a sample of young children in Chile, where school and childcare closures lasted for about a year. We use a unique dataset collected face-to-face in December 2020, which includes child development indicators for general development, language development, social-emotional development, and executive function. We are able to use a first difference strategy because Chile has a history of collecting longitudinal data on children as part of their national social policies monitoring strategy. This allows us to construct a valid comparison group from the 2017 longitudinal data. We find adverse impacts on children in 2020 compared to children interviewed in 2017 in most development areas. In particular, nine months after the start of the pandemic, we find a loss in language development of 0.25 SDs. This is equivalent to the impact on a childs language development of having a mother with approximately five years less education. Timely policies are needed to mitigate these enormous losses.

Abstract:
Review question / Objective: Reported levels of amyloid-beta and tau in human cerebrospinal fluid (CSF) are evaluated to discover if these biochemical markers can predict the transition from Mild Cognitive Impairment (MCI) to Alzheimer’s disease (AD). A systematic review and quantitative meta-analyses are performed to test relationships between three potential biomarkers in CSF (Aβ(1-42), T-tau, and P-tau181) and the evolution of AD in longitudinal evaluations of levels relative to baseline, using prior-published experimental data. The primary focus of the analysis is on the period describing the transition of a patient from MCI to AD, where it is critical to discover the main biomarker characteristics that differentiate patient outcomes for those who have a stable form of MCI, and those who progress to a confirmed diagnosis of AD. A secondary purpose of the review was to examine the status of iron in CSF as a function of disease status.

Abstract:
We develop and estimate a model of child care markets that endogenizes both demand and supply. On the demand side, families with a child make consumption, labor supply, and child-care decisions within a static, unitary household model. On the supply side, child care providers make entry, price, and quality decisions under monopolistic competition. Child development is a function of the time spent with each parent and at the child care center; these inputs vary in their impact. We estimate the structural parameters of the model using the 2003 Early Childhood Longitudinal Study, which contains information on parental employment and wages, child care choices, child development, and center quality. We use our estimates to evaluate the impact of several policies, including vouchers, cash transfers, quality regulations, and public provision. Among these, a combination of quality regulation and vouchers for working families leads to the greatest gains in average child development and to a large expansion in child care use and female labor supply, all at a relatively low fiscal cost.
