Central Nervous System Complications of Sickle Cell Disease in Children: An Overview

Complications involving the central nervous system are among the most devastating manifestations of sickle cell disease. Although overt stroke occurs in 1 in 10 children with Hemoglobin SS, “silent cerebral infarcts” are even more frequent. Both are associated with significant neuropsychological deficits. The end result of these effects on the CNS often is diminished school performance. The use of transcranial Doppler ultrasonography screening allows the identification of patients at high risk for clinical stroke as well as stroke prevention by chronic transfusion. However, definitive prophylaxis and treatment for most CNS complications of sickle cell disease have yet to be determined.     

Resilience is associated with better recovery in Chinese people diagnosed with coronary heart disease

This study investigated the impact of personal resilience (a composite measure of optimism, perceived control and self-esteem) on outcome measures in 67 Chinese coronary heart disease patients in response to an 8-week rehabilitation programme. The effect of personal resilience on posttraumatic growth attributed to the onset of heart disease was also examined. Results indicated that coronary heart disease patients high in personal resilience achieved better outcomes than those low in personal resilience, as indicated by higher physical and mental summary measures in SF-36, lower cholesterol levels and better performance on the 6?min walk test. Moreover, personal resilience was demonstrated to be a significant predictor of the level of posttraumatic growth although the rehabilitation programme exerted a weak mediating effect on the link between personal resilience and posttraumatic growth. Findings were discussed in relation to clinical implications of the construct of personal resilience and the intervention programme.     

Lifestyle differences between smokers,ex-smokers and non-smokers,and implications for their health

Abstract

Much evidence has been published in order to demonstrate that smoking cessation leads to a decrease in morbidity and mortality. Using data from the Health and Lifestyle Survey respondents were divided into three groups: smokers, ex-smokers and non-smokers and lifestyle characteristics such as diet and exercise were compared. Smokers were more likely to eat chips (French fries), fried food, butter and less likely to eat fresh fruit in winter, green vegetables and margarine high in polyunsaturated fats. Non-smokers were more likely than smokers and ex-smokers to take part in keepfit, jogging and swimming. Non-smokers in smoking households were more likely than non-smokers in non-smoking households to eat fried food, chips and butter and less likely to eat fruit in winter or margarine high in polyunsaturated fats. Results suggest that part of the assumed health benefits of smoking cessation are due to ex-smokers having a healthier diet than that of smokers.     

Chinese values and health: A cultural-level examination

Abstract

Previous research has identified two factors from the Chinese Value Survey, Integration vs Inwardness and Reputation vs Morality. In an effort to further establish their validities, the scores of a student sample on these two dimensions were calculated for each of 23 countries. These value profiles were then used as predictors of a number of health indices, after partialing out the confounding influence of per capita GNP. This country-level analysis revealed many relationships between the two value dimensions and 1. longevity measures, 2. modes of death, 3. health endangering behaviors, and 4. indicators of social well-being. These findings were related to theorizing about cultural emphases on individualism and on material success. It is hoped that this research will stimulate more comprehensive within-and cross-cultural research on the link between values and health.     

Mindfulness and integrative self‐knowledge: Relationships with health‐related variables

This study examined how mindfulness and integrative self‐knowledge were related to health‐related issues. Men in general population (n = 103) and coronary heart disease samples (n = 101) completed the Mindful Attention Awareness Scale, the Integrative Self‐knowledge Scale, the Type 2 subscale of the Interpersonal Reactions Inventory, the Perceived Stress Scale, and the Anxiety and Depression Scales. In both samples, there was a moderate positive correlation between mindfulness and integrative self‐knowledge and they were negatively correlated with all health‐related variables. However, only integrative self‐knowledge explained independent variance in health‐related variables. Specifically, in both samples, the relationship between mindfulness and health‐related variables was mediated by integrative self‐knowledge. Mindfulness and integrative self‐knowledge are related domains of self‐awareness that are associated with a range of health‐related variables. These relationships are robust across samples drawn from general population and patients with coronary heart disease. The finding that integrative self‐knowledge explained additional variance in the health‐related variables after the contribution of mindfulness had been accounted for suggests that reflective self‐awareness in integrative self‐knowledge may make a unique contribution to the explanation of individual differences in health variables.     

Does Response Inhibition Have Pre- and Postdiagnostic Utility in Parkinson's Disease?

ABSTRACT. Parkinson's disease (Pd) is the second most prevalent degenerative neurological condition worldwide. Improving and sustaining quality of life is an important goal for Parkinson's patients. Key areas of focus to achieve this goal include earlier diagnosis and individualized treatment. In this review the authors discuss impulse control in Pd and examine how measures of impulse control from a response inhibition task may provide clinically useful information (a) within an objective test battery to aid earlier diagnosis of Pd and (b) in postdiagnostic Pd, to better identify individuals at risk of developing impulse control disorders with dopaminergic medication.     

The free and cued selective reminding test: Validation for mild cognitive impairment and Alzheimer's disease

The International Working Group on Alzheimer's disease (AD) suggested the free and cued selective reminding test (FCSRT) to assess memory, as it showed high sensitivity and specificity in the differentiation of AD from healthy controls and other dementias. The FCSRT involves the use of selective reminding with semantic cueing in memory assessment. This study aims to validate the FCSRT for mild cognitive impairment (MCI) and AD through the analysis of the diagnostic accuracy and the suggestion of cut‐off scores. Patients were classified into two groups according to standard criteria: MCI (n = 100) and AD (n = 70). A matched control group (n = 101) of cognitively healthy subjects was included. The reliability and the validity of the FCSRT were analysed on the immediate (IR) and delayed (DR) recalls. The Cronbach's alpha was 0.915 for the IR and 0.879 for the DR. The total recall measures revealed good areas under the curve for MCI (IR: .818; DR: .828) and excellent for AD (IR: .987; DR: .991). Furthermore, the MCI group was subdivided with respect to a non‐similar/similar AD pattern of impairment, with almost half of the subjects showing an AD‐like decline. This analysis represents a novel contribution regarding the properties of the FCSRT in illustrating the heterogeneity of MCI at baseline. The FCSRT has proved to be a very useful tool in the characterization of the memory impairment of the AD spectrum.     

Neuropsychological indicators of preclinical Alzheimer’s disease among depressed older adults

Older adults with major depressive disorder (MDD) may also have preclinical Alzheimer’s disease (AD). Differential diagnosis is quite challenging due to the overlapping symptoms of MDD and AD. In the current study, we predicted that impaired long-term memory (an area most affected in early AD), but not executive function (an area affected in MDD and AD), would distinguish older depressed patients who developed AD from those who did not. Patients (N = 120) assessed as having MDD but not dementia at baseline were administered tests of cognitive function and followed longitudinally for subsequent diagnosis of AD. Using structural equation modeling we found a latent construct of long-term memory to be associated with AD to a greater extent than executive functioning. Additional analyses to enhance clinical utility of findings indicated that individual tests of episodic memory were most predictive of AD status. Tests of long-term memory can be utilized by the clinician when assessing for preclinical AD among depressed elderly.     

依那普利叶酸片与依那普利片改善动脉硬化效果比较

探讨马来酸依那普利叶酸片对冠心病患者血清同型半胱氨酸（Hcy）及脉搏波传导速度（PWV）的影响。选取108例冠心痛患者随机分为依叶组（口服马来酸依那普利叶酸片1片,每日1次）和依苏组（口服依那普利片1片,每日1次）,疗程6个月,另选取冠状动脉造影为非冠心病患者40例作对照。检测各组患者治疗前后血清Hcy水平及PWV,并进行比较。冠心病患者血清Hcy水平及PWV较非冠t心病患者明显升高（P〈o．01）,治疗6个月后,两组冠心病患者血清Hcy水平及PWV均较治疗前降低（P〈o．05,P〈o．01）,而依叶组血清Hcy水平及PWV较依苏组降低更为显著（P〈0．05,P〈0．01）。冠心病常规治疗的基础上联用叶酸可进一步降低患者血清Hcy水平及PWV,从而改善患者内皮功能及动脉硬化。
