Introduction: The neuropsychological battery of the Uniform Data Set (UDSNB) was implemented in 2005 by the National Institute on Aging (NIA) Alzheimer Disease Centers program to measure cognitive performance in dementia and mild cognitive impairment due to Alzheimer Disease. This paper describes a revision, the UDSNB 3.0., Methods: The Neuropsychology Work Group of the NIA Clinical Task Force recommended revisions through a process of due diligence to address shortcomings of the original battery. The UDSNB 3.0 covers episodic memory, processing speed, executive function, language, and constructional ability. Data from 3602 cognitively normal participants in the National Alzheimer Coordinating Center database were analyzed., Results: Descriptive statistics are presented. Multivariable linear regression analyses demonstrated score differences by age, sex, and education and were also used to create a normative calculator available online., Discussion: The UDSNB 3.0 neuropsychological battery provides a valuable non proprietary resource for conducting research on cognitive aging and dementia.

Objective: The aim of the study was to determine the relationship of lifestyle factors and neurocognitive functioning in older adults with vascular risk factors and cognitive impairment, no dementia (CIND)., Methods: One hundred sixty adults (M [SD] = 65.4 [6.8] years) with CIND completed neurocognitive assessments of executive function, processing speed, and memory. Objective measures of physical activity using accelerometry, aerobic capacity determined by exercise testing, and dietary habits quantified by the Food Frequency Questionnaire and 4-Day Food Diary to assess adherence to the Mediterranean and Dietary Approaches to Stop Hypertension (DASH) diets were obtained to assess direct effects with neurocognition. Potential indirect associations of high-sensitivity C-reactive protein and the Framingham Stroke Risk Profile also were examined., Results: Greater aerobic capacity (β = 0.24) and daily physical activity (β = 0.15) were associated with better executive functioning/processing speed and verbal memory (βs = 0.24; 0.16). Adherence to the DASH diet was associated with better verbal memory (β = 0.17). Greater high-sensitivity C-reactive protein (βs = -0.14; -0.21) and Framingham Stroke Risk Profile (β = -0.18; -0.18) were associated with poorer executive functioning/processing speed and verbal memory. Greater stroke risk partially mediated the association of aerobic capacity with executive functioning/processing speed, and verbal memory and greater inflammation partially mediated the association of physical activity and aerobic fitness, with verbal memory., Conclusions: Higher levels of physical activity, aerobic fitness, and adherence to the DASH diet are associated with better neurocognitive performance in adults with CIND. These findings suggest that the adoption of healthy lifestyle habits could reduce the risk of neurocognitive decline in vulnerable older adults., Clinical Trial Registration: NCT01573546.

Objectives: Observational studies suggest reduced risk of Alzheimer disease (AD) in users of hormone therapy (HT), but trials show higher risk. We examined whether the association of HT with AD varies with timing or type of HT use., Methods: Between 1995 and 2006, the population-based Cache County Study followed 1,768 women who had provided a detailed history on age at menopause and use of HT. During this interval, 176 women developed incident AD. Cox proportional hazard models evaluated the association of HT use with AD, overall and in relation to timing, duration of use, and type (opposed vs unopposed) of HT., Results: Women who used any type of HT within 5 years of menopause had 30% less risk of AD (95% confidence interval 0.49-0.99), especially if use was for 10 or more years. By contrast, AD risk was not reduced among those who had initiated HT 5 or more years after menopause. Instead, rates were increased among those who began "opposed" estrogen-progestin compounds within the 3 years preceding the Cache County Study baseline (adjusted hazard ratio 1.93; 95% confidence interval 0.94-3.96). This last hazard ratio was similar to the ratio of 2.05 reported in randomized trial participants assigned to opposed HT., Conclusions: Association of HT use and risk of AD may depend on timing of use. Although possibly beneficial if taken during a critical window near menopause, HT (especially opposed compounds) initiated in later life may be associated with increased risk. The relation of AD risk to timing and type of HT deserves further study.

Objectives: To assess the effects of aerobic exercise training on neurocognitive performance. Although the effects of exercise on neurocognition have been the subject of several previous reviews and meta-analyses, they have been hampered by methodological shortcomings and are now outdated as a result of the recent publication of several large-scale, randomized, controlled trials (RCTs)., Methods: We conducted a systematic literature review of RCTs examining the association between aerobic exercise training on neurocognitive performance between January 1966 and July 2009. Suitable studies were selected for inclusion according to the following criteria: randomized treatment allocation; mean age > or =18 years of age; duration of treatment >1 month; incorporated aerobic exercise components; supervised exercise training; the presence of a nonaerobic-exercise control group; and sufficient information to derive effect size data., Results: Twenty-nine studies met inclusion criteria and were included in our analyses, representing data from 2049 participants and 234 effect sizes. Individuals randomly assigned to receive aerobic exercise training demonstrated modest improvements in attention and processing speed (g = 0.158; 95% confidence interval [CI]; 0.055-0.260; p = .003), executive function (g = 0.123; 95% CI, 0.021-0.225; p = .018), and memory (g = 0.128; 95% CI, 0.015-0.241; p = .026)., Conclusions: Aerobic exercise training is associated with modest improvements in attention and processing speed, executive function, and memory, although the effects of exercise on working memory are less consistent. Rigorous RCTs are needed with larger samples, appropriate controls, and longer follow-up periods.

Background: Renal-transplant recipients are at increased risk of developing skin cancers, especially squamous cell carcinoma. We have carried out a comprehensive epidemiologic review of skin cancers occurring in a population receiving transplants in Oxford over a 21-year period, where nearly all patients have remained under the care of the Oxford Transplant Centre., Methods: Between 1975 and 1996, 1,360 renal transplants were performed in 1,115 patients. Skin cancer data were reviewed in 979 patients from this group who remained under the care of the Oxford Transplant Centre. The lesions included in the analysis were histologically confirmed basal cell carcinoma, Bowen's disease, squamous cell carcinoma, keratoacanthoma, malignant melanoma, Merkel cell tumor, and sebaceous carcinoma., Results: One hundred eighty-seven (19.1%) transplant patients developed at least one skin malignancy. The rate of skin cancer was 141 per 1,000 person years at risk. Sixty-four percent of patients with skin cancer had multiple lesions (maximum 50). Squamous cell carcinoma was the most common skin cancer to develop and the most common first skin cancer to present. The mean time to presentation of the first skin cancer was 8 years. Six patients developed nodal metastases, and two patients died secondary to skin cancer. Risk factors identified were increasing age at transplantation, recipient sex, total time of exposure to immunosuppression, increased creatinine levels at 1 year, and graft relation. The cumulative incidence of skin cancer reached 61% at 20 years after transplantation., Conclusion: The data from this study suggest that more patients develop skin malignancies than previously reported from Europe. It is important to advise patients before transplantation in regard to skin complications, provide regular dermatological follow-up, and tailor immunosuppressive regimen to minimum doses to be compatible with good graft function.

Objective: To evaluate gender-related differences in quality of life (QOL) and cognitive function 1 year after coronary artery bypass surgery (CABG) after adjusting for known baseline differences., Materials and Methods: Two hundred eighty patients (96 women and 184 men) underwent neurocognitive and QOL evaluation at baseline (preoperatively) and at 1 year after CABG. Multivariable linear regression was used to assess the relationship of gender to follow-up QOL and cognitive function. Measures used to evaluate QOL were IADL, DASI, work activities (SF-36), social activities, social support, general health perception (SF-36), CESD, STAI, and symptom limitations. Cognitive function was measured with a battery of performance-based neuropsychological tests, reduced to a four-cognitive domain scores with factor analysis, and a self-report measure of cognitive difficulties. Covariates in multiple regression models included age, years of education, marital status, Charlson Comorbidity Index, hypertension, diabetes, race, and baseline QOL/cognitive status., Results: Female patients showed significantly worse outcome than male patients at 1 year follow-up in several key areas of QOL. After adjusting for baseline differences, women are at greater risk for increased cognitive difficulties (p= 0.04) and anxiety (p= 0.03), as well as impaired DASI (p= 0.02), IADL (p= 0.03), and work activities (p= 0.02). Cognitive sequelae attributable to bypass surgery were similar between men and women., Conclusions: Even after adjusting for known risk factors for compromised QOL and cognitive functioning, women do not show the same long-term quality benefits of CABG surgery that men do.

Objectives: To evaluate the efficacy of nizatidine, a histamine H2-blocking drug, in delaying the progression of cognitive impairment in older adults with Alzheimer disease (AD)., Design: A one-year, randomized, double-blind, placebo-controlled trial., Participants: Fifty-one older men and women aged 67 to 96 years with AD were recruited from the Cache County Study on Memory in Aging., Methods: Patients were stratified by age and by the presence of one or more epsilon 4 alleles at the APOE locus, then randomized to receive nizatidine 75 mg (Axid ARTM, Whitehall Robins) or a matching placebo tablet twice daily. Cognitive outcomes were assessed at baseline, six, and twelve months after enrollment using tests from the CERAD battery and additional measures of visuospatial memory, verbal memory, and verbal fluency., Results: Subjects showed significant declines in language, fluency, and praxis but most measures of memory had already "bottomed out." Intention-to-treat and compliance-based analyses showed no effect of nizatidine on any of the cognitive outcome measures over the one-year study interval., Conclusions: These results do not support claims for the efficacy of nizatidine in over-the-counter dosages as a means of preventing symptom progression in AD.

A 39-year-old right-handed woman suffered a ruptured pericallosal aneurysm. Serial MRI studies showed damage to the genu and most of the body of the corpus callosum but not the splenium. Both supplementary motor areas (SMA) appeared intact. We studied the patient's praxis performance at intervals over a 4-month period with a standardized battery. The study suggests that apraxia seen in patients with callosal lesions is probably due to the callosal damage, not to the usually associated SMA lesion. Our findings support Liepmann's idea that the left hemisphere is dominant for praxis in both hands. We propose, however, that the dominance effect is related to the type of test given and varies among individuals. As regards the latter, in some individuals the left hemisphere is strongly dominant for motor tasks, while in others it is less so. As regards the type of test, the most enduring left-hand apraxia is seen in verbal, not visuomotor tests.

An attempt was made at correcting the specific lysosomal enzyme deficiencies in 7 children with Hunter's or Hurler's diseases by transplantation of fetal fibroblasts. In spite of pretreating the young patients with stored blood, following a procedure employed successfully to avoid rejection of kidneys from incompatible donors, the use of serum-free media for culturing the cells before being harvested and incubation of the cells with chorionic gonadotrophin, the transplantation of fetal fibroblasts was not associated with biochemical or clinical changes. None of the seven patients showed immune reactions against the transplanted cells, HLA antigens, or the missing enzymes.
