The objective of the present study was to determine the clinical and construct validity of the assessment of disabilities in stroke patients with apraxia. Disabilities were assessed by means of observation of activities of daily living (ADL), such as washing the face and upper body and putting on a blouse or shirt. The study was carried out at occupational therapy departments in general hospitals, rehabilitation centres, and nursing homes. Patients diagnosed to have had a stroke in the left hemisphere and to have apraxia participated in the study (n = 45, 21 males, 24 females age 39–91). Guidelines were offered for the ADL observations and the assessment of disabilities in these activities. Clinical validity was investigated by comparing the scores of the patients with those of a group of stroke patients without apraxia (n = 36, 14 males, 22 females age 35–88). Construct validity was examined by investigating relationships between several measures of interest: an apraxia test, a motor functioning test, a set of ADL observations, and the Barthel index as a general measure of disability. Comparison of the results of the patients with apraxia with the control group of stroke patients without apraxia showed that the clinical validity of the ADL observations is good: On the basis of the ADL observations, differences between patients with apraxia and patients without apraxia are measured. Correlation analyses of the group of patients with apraxia showed that the ADL observations were highly associated with apraxia, but only to a lesser degree with motor impairments; while motor impairments correlated strongly with the Barthel index (a general measure of physical disability), but only marginally with ADL observations. A LISREL analysis supported these findings. The results indicate that ADL observations have clinical validity and that the construct validity of the observational method is good. ADL observations appear to measure disability ties caused by apraxia in stroke patients. 相似文献
The aim of this study was to evaluate cardiac, biochemical and endocrine differences between female adolescents with anorexia nervosa (AN) with and without pericardial effusions. We studied 128 female adolescents (9.8–17.7 years) with anorexia nervosa (AN) diagnosed according to DSM-IV (American Psychiatric Association, 1994American Psychiatric Association. 1994. Diagnostic and statistical manual of mental disorders, 4th, Washington, DC: Author. [Google Scholar]) criteria. They all underwent an echocardiographic evaluation. In 29 patients (22.2 %) a pericardial effusion (ranging between ≥ 0.35–2.5 cm) was noted. None of the patients were clinically symptomatic. After 3 months of refeeding, the effusions disappeared in 18/29 patients while in 7/29 patients a pericardial effusion > 0.3 cm persisted. Risk factors for development of effusions were a BMI ≤ 13,5 kg/m², weight loss ≥ 25% and IGF-1-level ≤100 ng/ml. Pericardial effusions are common in adolescent AN patients. They are mostly asymptomatic not requiring any intervention and spontaneously regress with refeeding. They are more common in the patients with the most significant weight loss. 相似文献
Yardsticks have been developed to measure dental arch relations in cleft lip and palate (CLP) patients as diagnostic proxies for the underlying skeletal relationship. Travelling with plaster casts to compare results between CLP centres is inefficient so the aim of this study was to investigate the reliability of using digital models or photographs of dental casts instead of plaster casts for rating dental arch relationships in children with complete bilateral cleft lip and palate (CBCLP). Dental casts of children with CBCLP (n=20) were included. Plaster casts, digital models and photographs of the plaster casts were available for all the children at 6, 9, and 12 years of age. All three record formats were scored using the bilateral cleft lip and palate (BCLP) yardstick by four observers in random order. No significant differences were found for the BCLP yardstick scores among the three formats. The interobserver weighted kappa scores were between 0.672 and 0.934. Comparison between the formats per observer resulted in weighted kappa scores between 0.692 and 0.885. It is concluded that digital models and photographs of dental casts can be used for rating dental arch relationships in patients with CBCLP. These formats are a reliable alternative for BCLP yardstick assessments on conventional plaster casts. 相似文献
The importance of culture for food consumption is widely acknowledged, as well as the fact that culture-based resources (“cultural capital”) differ between educational groups. Since current explanations for educational inequalities in healthy and unhealthy food consumption (e.g. economic capital, social capital) are unable to fully explain this gradient, we aim to investigate a new explanation for educational inequalities in healthy food consumption, i.e. the role of cultural capital.
Methods
Data were obtained cross-sectionally by a postal survey among participants of the GLOBE study in the Netherlands in 2011 (N?=?2953; response 67.1%). The survey measured respondents’ highest attained educational level, food-related cultural capital (institutionalised, objectivised and incorporated cultural capital), economic capital (e.g. home ownership, financial strain), social capital (e.g. social support, health-related social leverage, interpersonal relationships), and frequency of consumption of healthy and unhealthy food products. Two general outcomes (overall healthy food consumption, and overall unhealthy food consumption), and seven specific food consumption outcomes were constructed, and prevalence ratios (PR) were estimated in Poisson regression models with robust variance.
Results
Cultural capital was significantly associated with all food outcomes, also when social and economic capital were taken into account. Those with low levels of cultural capital were more likely to have a lower overall healthy food consumption (PR 1.35, 95% CI 1.22–1.49), a lower consumption of whole wheat bread (PR 1.21, 95% CI 1.05–1.38), vegetables (PR 1.55, 95% CI 1.40–1.71), and meat-substitutes and fish (PR 1.74, 95% CI 1.53–1.97), and a higher consumption of fried food (PR 1.59, 95% CI 1.31–1.93). Social capital was positively associated with overall healthy food consumption, whole wheat bread consumption, and the consumption of fish and meat-substitutes, and economic capital with none of the outcomes. The PR of the lowest educational group to have a low overall healthy food consumption decreased from 1.48 (95% CI 1.28–1.73) to 1.22 (95% CI 1.04–1.43) when cultural, social and economic capital were taken into account.
Conclusions
Cultural capital contributed to the explanation of educational inequalities in food consumption in The Netherlands, over and above economic and social capital. The socialisation processes through which cultural capital is acquired could offer new entry-points for the promotion of healthy food consumption among low educational groups.
Daytime sleepiness is highly prevalent in the general adult population and has been linked to an increased risk of workplace and vehicle accidents, lower professional performance and poorer health. Despite the established relationship between noise and daytime sleepiness, little research has explored the individual-level spatial distribution of noise-related sleep disturbances. We assessed the spatial dependence of daytime sleepiness and tested whether clusters of individuals exhibiting higher daytime sleepiness were characterized by higher nocturnal noise levels than other clusters.
Design and Methods
Population-based cross-sectional study, in the city of Lausanne, Switzerland.Sleepiness was measured using the Epworth Sleepiness Scale (ESS) for 3697 georeferenced individuals from the CoLaus|PsyCoLaus cohort (period?=?2009–2012). We used the sonBASE georeferenced database produced by the Swiss Federal Office for the Environment to characterize nighttime road traffic noise exposure throughout the city. We used the GeoDa software program to calculate the Getis-Ord Gi* statistics for unadjusted and adjusted ESS in order to detect spatial clusters of high and low ESS values. Modeled nighttime noise exposure from road and rail traffic was compared across ESS clusters.
Results
Daytime sleepiness was not randomly distributed and showed a significant spatial dependence. The median nighttime traffic noise exposure was significantly different across the three ESS Getis cluster classes (p?<?0.001). The mean nighttime noise exposure in the high ESS cluster class was 47.6, dB(A) 5.2?dB(A) higher than in low clusters (p?<?0.001) and 2.1?dB(A) higher than in the neutral class (p?<?0.001). These associations were independent of major potential confounders including body mass index and neighborhood income level.
Conclusions
Clusters of higher daytime sleepiness in adults are associated with higher median nighttime noise levels. The identification of these clusters can guide tailored public health interventions. 相似文献
Introduction: Due to its close connection with the renal system, urine is considered a valuable source of information in kidney disease research. Peptidomics methods focus on the discovery of endogenous peptides, given their wide range of biological functions and diagnostic and therapeutic potential. Representing a non-invasive and sensitive method, technological prospects of urinary peptidomics should be evaluated in the context of drug discovery and research.
Areas covered: This review describes urinary peptidomics with focus on its application in drug research in the field of kidney diseases. The authors provide an overview of current achievements and potential future applications.
Expert opinion: The urinary peptidome is a dynamically changing source of information, able to reflect sudden and long-term changes affecting the renal system. Studies utilizing urinary peptidomics techniques have demonstrated their value in patient stratification and detection of early pathological changes in kidney disease. Serving as a liquid biopsy, urinary peptides are an invaluable tool for drug response monitoring. Nevertheless, peptidomics is largely underexplored in drug research in general, as evidenced by the scarce number of scientific publications on this topic. Further progress will be driven by the successful validation of current discoveries and continued efforts to improve the translation of results into therapeutic applications. 相似文献
