Translation and validation of Chinese version of the Problems in Everyday Living (PEDL) test in patients with mild cognitive impairment

ABSTRACT Background: Cognitive impairment places older adults at increased risk of functional decline, injuries, and hospitalization. Assessments to determine whether older persons are still capable of meeting the cognitive challenges of everyday living are crucial to ensure their safe and independent living in the community. The present study aims to translate and validate the Chinese version of the Problems in Everyday Living (PEDL) test for use in Chinese population with mild cognitive impairment (MCI). Methods: The cultural relevancy and content validity of the Chinese version of PEDL (C-PEDL) was evaluated by a seven-member expert panel. Forty patients with MCI and 40 cognitively healthy participants were recruited to examine the psychometric properties of C-PEDL. Results: Significant differences in the C-PEDL scores were found between the patients with MCI and the cognitively healthy controls in both educated (F = 9.96, p = 0.003) and illiterate (F = 10.43, p = 0.004) populations. The C-PEDL had excellent test-retest and inter-rater reliabilities, with intraclass correlation coefficient at 0.95 and 0.99 respectively. The internal consistency of C-PEDL was acceptable with Chronbach's α at 0.69. The C-PEDL had moderate correlation with the Mini-Mental State Examination (r = 0.45, p = 0.004) and the Category Verbal Fluency Test (r = 0.40, p = 0.012), and a moderate negative Spearman's correlation with the Global Deteriorating Scale (r = –0.42, p = 0.007). Conclusions: The C-PEDL is a valid and reliable test for assessing the everyday problem-solving ability in Chinese older population with MCI.
Metabolic Mediators of the Association Between Adult Weight Gain and Colorectal Cancer: Data From the European Prospective Investigation into Cancer and Nutrition (EPIC) Cohort

Evidence indicates that gaining weight in adult life is associated with an elevated risk of colorectal cancer; however, biological mechanisms that may explain this association remain unclear. We evaluated the mediation effect of 20 different biomarkers on the relationship between adult weight gain and colorectal cancer, using data from a prospective nested case-control study of 452 incident cases diagnosed between 1992 and 2003 and matched within risk sets to 452 controls within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. The proportions of mediated effects (%) were estimated on the basis of differences in percent effect changes in conditional logistic regression models with and without additional adjustment for individual biomarkers. Greater adult weight gain (≥300 g/year vs. <300 g/year) was associated with a higher risk of colon cancer (multivariable-adjusted relative risk = 1.54, 95% confidence interval: 1.07, 2.24) but not rectal cancer (relative risk = 1.07, 95% confidence interval: 0.68, 1.66). This association was accounted for mostly by attained waist circumference (reduction of 61%) and by the biomarkers soluble leptin receptor (reduction of 43%) and glycated hemoglobin (reduction of 28%). These novel data suggest that the observed association between adult weight gain and colon cancer could be primarily explained by attained abdominal fatness and biomarkers of metabolic dysfunction.
Original Contribution AssociationsBetweenAir Quality Changes andBiomarkers of Systemic InflammationDuring the 2014Nanjing YouthOlympics: AQuasi-Experimental Study

There is increasing interest in quasi-experimental research to evaluate whether actions taken to improve air quality will benefit public health. We conducted a quasi-experimental study to evaluate inflammatory response to changes in air quality during the 2014 Nanjing Youth Olympics in China. We repeatedly measured 8 biomarkers of systemic inflammation in 31 healthy adults and obtained hourly air pollutant concentrations from a nearby fixedsite monitoring station. We used linear mixed-effect models to examine the associations between air quality changes and blood biomarkers. Air pollutant concentrations decreased apparently during the Youth Olympics. Concomitantly, we observed significant decreases in levels of soluble cluster of differentiation 40 (CD40) ligand and interleukin 1β (geometric means ratios were 0.45 and 0.24, respectively) from the pre-Olympic period to the intra-Olympic period. Afterwards, levels of C-reactive protein and vascular cell adhesion molecule 1 increased significantly (geometric means ratios were 2.22 and 1.29, respectively) in the post-Olympic period. Fine particulate matter and ozone were significantly associated with soluble CD40 ligand, P-selectin, interleukin 1β, intercellular adhesion molecule 1, and vascular cell adhesion molecule 1. Other pollutants showed positive but nonsignificant associations. Our study indicated that reduced air pollution, especially fine particulate matter and ozone, during the 2014 Nanjing Youth Olympics was associated with alleviated systemic inflammation in healthy adults.
Operational definitions of successful aging: a systematic review

ABSTRACT Background: Half a century after the inception of the term “successful aging (SA),” a consensus definition has not emerged. The current study aims to provide a comprehensive snapshot of operational definitions of SA. Methods: A systematic review across MedLine, PsycInfo, CINAHL, EMBASE, and ISI Web of Knowledge of quantitative operational definitions of SA was conducted. Results: Of the 105 operational definitions, across 84 included studies using unique models, 92.4% (97) included physiological constructs (e.g. physical functioning), 49.5% (52) engagement constructs (e.g. involvement in voluntary work), 48.6% (51) well-being constructs (e.g. life satisfaction), 25.7% (27) personal resources (e.g. resilience), and 5.7% (6) extrinsic factors (e.g. finances). Thirty-four definitions consisted of a single construct, 28 of two constructs, 27 of three constructs, 13 of four constructs, and two of five constructs. The operational definitions utilized in the included studies identify between <1% and >90% of study participants as successfully aging. Conclusions: The heterogeneity of these results strongly suggests the multidimensionality of SA and the difficulty in categorizing usual versus successful aging. Although the majority of operationalizations reveal a biomedical focus, studies increasingly use psychosocial and lay components. Lack of consistency in the definition of SA is a fundamental weakness of SA research.
Translucência nucal aumentada e cariótipo normal: evolução pré e pós-natal

OBJECTIVE: The aim of this study was to evaluate pregnancy and postnatal outcomes of fetuses with increased nuchal translucency thickness (NT) and normal karyotype. METHODS: Two hundred seventy five fetuses with increased NT were examined with karyotyping analysis, serial ultrasound scans, echocardiography and postnatal clinical and genetic evaluation at the Fetal Medicine Unit - Department of Obstetrics - Sao Paulo University. RESULTS: The karyotype was abnormal in 14.2% of the cases and normal in 85.8%. In cases with normal karyotype 24.7% presented structural abnormalities at the anomaly scan, one third of these were major malformations with 35.7% of heart defects. Adverse pregnancy outcome such as miscarriages, intrauterine and neonatal deaths occurred in 10.2% of cases. Of the infants 72.7% had postnatal examination, with 14.8% presenting abnormalities. Chances of having a live and healthy child decreased with increased NT thickness, and were of 37.5% for NT above 4.5mm. CONCLUSION: In cases with increased NT thickness and normal karyotype, the frequency of fetal malformations, especially heart defects, adverse pregnancy outcome and postnatal abnormalities is related to the NT thickness.
Are depressive symptomatology and self-focused attention associated with subjective memory impairment in older adults?

ABSTRACT Background: Subjective memory impairment (SMI) refers to conditions in which people complain of memory problems despite intact cognition. The primary purpose of the present study was to examine the roles of self-focused attention and depressive symptomatology in subjective memory complaints. Methods: One hundred and eight patients who visited a memory disorder clinic with complaints of memory decline, but who were found on subsequent neuropsychological assessment to have normal cognitive function, were recruited to participate in the study. The severity of subjective memory complaints was measured with the modified Multifactorial Memory Questionnaire. In addition, neuropsychological functions, self-focused attention, and depressive symptomatology were also assessed. Results: The results showed that the severity of SMI was not significantly correlated with any of the neuropsychological test scores except for the complex figure copy. The severity of SMI, however, was significantly correlated with self-focused attention and depressive symptomatology. Hierarchical regression analysis revealed that self-focused attention and depressive symptomatology significantly contributed to the severity of subjective memory complaints over and above the neuropsychological test performance. The interaction effects between self-focused attention/depressive symptomatology and objective memory performance on the severity of SMI were not significant. Conclusions: In conclusion, self-focused attention and depressive symptomatology appear to play important roles in the severity of SMI, even though it is not clear how these factors interact with objective memory performance. Clinical implications as well as limitations of the present study were discussed.
Complement Profile in Neonates of Different Gestational Ages

Blood levels of regulators of the complement system in preterm babies were reported in few studies only. The aim of this study was to set up a complement profile in premature and term babies focusing on the development of blood levels of MBL, key regulatory proteins and on classical pathway activity, which may allow an estimation of potential susceptibility to infection. Complement activity (CH50), levels of mannan‐binding lectin (MBL), complement regulators (factors H and I, C1 inhibitor, properdin) and C3a as marker of complement activation were assessed in three groups of healthy newborns: (1) prematures (≤34 weeks); (2) late prematures (>34–<37 weeks) and (3) term neonates (≥37 weeks). CH50 increased with gestational age with lower titres in cord blood than in day 5 post‐delivery venous blood. MBL concentrations were not significantly different among groups. Quantitative and functional C1 inhibitor were below adult normal range in prematures <34 weeks and lower in cord blood as compared to day 5. Factor I, factor H and properdin remained below adult values in all groups. Low C3a levels excluded that low complement titres were due to activation‐induced consumption. These results demonstrate the relative immaturity of the complement system and its regulation, especially in premature infants.
Material for : Relaxation dynamics in the merging of N independent condensates

Controlled quantum systems such as ultracold atoms can provide powerful platforms to study nonequilibrium dynamics of closed many-body quantum systems, especially since a complete theoretical description is generally challenging. In this Letter, we present a detailed study of the rich out-ofequilibrium dynamics of an adjustable number N of uncorrelated condensates after connecting them in a ring-shaped optical trap. We observe the formation of long-lived supercurrents and confirm the scaling of their winding number with N in agreement with the geodesic rule. Moreover, we provide insight into the microscopic mechanism that underlies the smoothening of the phase profile.
Age neutrality of the Young Schema Questionnaire in patients with a substance use disorder

ABSTRACT Background: Young's Schema Focused Therapy (SFT) is gaining popularity in the treatment of older adults. In the context of this therapy, the Young Schema Questionnaire (YSQ) was developed to assess the early maladaptive schemas (EMS). EMS are considered to be relatively stable over time, but research shows that questionnaires often lack face validity in older adults, which makes it difficult to investigate EMS in older adults and their stability across the lifespan. Methods: In the present cross-sectional study, we investigated the age neutrality of the Young Schema Questionnaire – Long Form in young (aged 18–34 years), middle-aged (aged 35–59 years), and older (aged 60–75 years) adults in a clinical sample of substance use disorders (N = 321) by examining potential differential item functioning (DIF). While investigating the stability of the schemas, we controlled for substance dependency and clinical symptoms by means of, respectively, the Drug Use Screening Inventory – Revised and the Symptom Checklist-90-R. Results: The Bonferroni-adjusted Liu–Agresti Cumulative Common Log-Odds Ratio confirmed large DIF for six items, divided across five schema scales (Mistrust/Abuse, Subjugation, Entitlement, Enmeshment and Self-sacrifice). Of the six items that presented DIF, only one item showed differential test functioning (Entitlement). Overall results show only 3% DIF, implying age neutrality of the questionnaire. Conclusions: Current results corroborate that most EMS scales are equally measured across age, and reliable comparisons can be made across the lifespan, allowing for good clinical practice and further research on SFT in older adults. Only for Entitlement, Enmeshment, and Insufficient Self-control, caution is needed when comparing mean scores across the age groups.
Methylenetetrahydrofolate Reductase C667T Polymorphism is Associated with Increased Risk of Coronary Artery Disease in a Chinese Population

Coronary artery disease (CAD) is a complex disease resulting from a combination of environmental and genetic factors. We hypothesized that polymorphisms in methylenetetrahydrofolate reductase (MTHFR) rs1801133 C/T, matrix metalloproteinases (MMPs)‐2, tumour necrosis factor (TNF)‐α, macrophage migration inhibitory factor (MIF) rs755622 G/C and cyclin D1 (CCND1) rs678653 G/C contribute to CAD susceptibility. We examined the association between the five polymorphisms and the risk of CAD in a Chinese population of 435 CAD patients and 480 controls. Genotyping was performed using matrix‐assisted laser desorption ionization/time‐of‐flight mass spectrometry (MALDI/TOF MS). When the MTHFR rs1801133 CC homozygote genotype was used as the reference group, the TT or CT/TT genotypes were associated with a significantly increased risk for CAD. The CT heterozygote genotype was not associated with the risk for CAD. Logistic regression analyses revealed that MMP‐2 rs243865 C/T, TNF‐α rs1800629 A/G, MIF rs755622 G/C and CCND1 rs678653 G/C polymorphisms were not associated with the risk of CAD. These findings suggest that the MTHFR rs1801133 C/T polymorphism is associated with CAD development. Future larger studies with other ethnic populations are required to confirm current findings.
Higher education affects accelerated cortical thinning in Alzheimer's disease: a 5-year preliminary longitudinal study

ABSTRACT Background: Epidemiological studies have reported that higher education (HE) is associated with a reduced risk of incident Alzheimer's disease (AD). However, after the clinical onset of AD, patients with HE levels show more rapid cognitive decline than patients with lower education (LE) levels. Although education level and cognition have been linked, there have been few longitudinal studies investigating the relationship between education level and cortical decline in patients with AD. The aim of this study was to compare the topography of cortical atrophy longitudinally between AD patients with HE (HE-AD) and AD patients with LE (LE-AD). Methods: We prospectively recruited 36 patients with early-stage AD and 14 normal controls. The patients were classified into two groups according to educational level, 23 HE-AD (>9 years) and 13 LE-AD (≤9 years). Results: As AD progressed over the 5-year longitudinal follow-ups, the HE-AD showed a significant group-by-time interaction in the right dorsolateral frontal and precuneus, and the left parahippocampal regions compared to the LE-AD. Conclusion: Our study reveals that the preliminary longitudinal effect of HE accelerates cortical atrophy in AD patients over time, which underlines the importance of education level for predicting prognosis.
Association between polymorphism of beta3‐adrenoceptor gene and overactive bladder

In human urinary bladder, beta3‐ARs play an important role in promoting detrusor relaxation during the storage phase of the micturition cycle. The present study investigated whether a Trp64Arg polymorphism of the gene encoding the beta3‐AR is associated with overactive bladder (OAB) syndrome.
Particulate Matter and Risk of Hospital Admission in the Kathmandu Valley, Nepal: A Case-Crossover Study

Air pollution is known to lead to a substantial health burden, but the majority of evidence is based on data from North America and Europe. Despite rising pollution levels, very limited information is available for South Asia. We investigated the impact of particulate matter with an aerodynamic diameter less than or equal to 10 μm (PM10) on hospitalization, by cause and subpopulation, in the Kathmandu Valley, an understudied and rapidly urbanizing region in Nepal. Individual-level daily inpatient hospitalization data (2004-2007) were collected from each of 6 major hospitals, as Nepal has no central data collection system. Time-stratified case-crossover analysis was used with interaction terms for potential effect modifiers (e.g., age, sex, and socioeconomic status), with adjustment for day of the week and weather. Daily PM10 concentrations averaged 120 μg/m3, with the daily maximum reaching 403 μg/m3. A 10-μg/m3 increase in PM10 level was associated with increased risks of hospitalization of 1.00% (95% confidence interval (CI): 0.62, 1.38), 1.70% (95% CI: 0.18, 3.25), and 2.29% (95% CI: 0.18, 4.43) for total, respiratory, and cardiovascular admissions, respectively. We did not find strong evidence of effect modification by age, sex, or socioeconomic status. These results, in combination with the high levels of exposure, indicate a potentially serious human health burden from air pollution in the Kathmandu Valley.
Trends in use of psychotropic medications among patients treated with cholinesterase inhibitors in Japan from 2002 to 2010

ABSTRACT Background: We aimed to examine trends in the use of psychotropic medications among elderly outpatients with dementia in Japan between 2002 and 2010. Methods: We used data from the 2002–2010 Survey of Medical Care Activities in Public Health Insurance (SMCA-PHI), a nationally representative cross-sectional survey of claims data for the month of June in every year. We included ambulatory care visits by patients aged 65 years or older who were prescribed cholinesterase inhibitors (n = 15,591), and identified use of any psychotropic medications during the survey month. Results: In 2008–2010, the most prevalently prescribed psychotropic medications to patients with dementia were sedatives-hypnotics (37.5%), antipsychotics (24.9%), antidepressants (13.0%), and mood-stabilizers (2.9%). Between 2002–2004 and 2008–2010, use of second-generation antipsychotics (SGAs) increased from 5.0% to 12.0%, while use of first-generation antipsychotics (FGAs) decreased from 20.6% to 12.9%. These numbers resulted in a 1.1-fold increase in the adjusted prevalence of the overall use of antipsychotics. Quetiapine and risperidone use showed a 4.8- and 1.8-fold increase, respectively, while haloperidol use showed a 2.3-fold decrease. Conclusions: Despite safety warnings against the use of antipsychotics for patients with dementia in several countries, our study revealed a slight increase in the extensive use of off-label antipsychotics over time in Japan. This finding indicates an urgent need for evaluation of the efficacy of antipsychotics for the approved treatment of severe agitation, aggression, and psychosis associated with dementia. Moreover, psychosocial interventions and antipsychotic withdrawal strategies are needed in order to reduce the overall prevalence of antipsychotic use.
Awareness of memory deficits in subjective cognitive decline, mild cognitive impairment, Alzheimer's disease and Parkinson's disease

ABSTRACT Background: Impaired awareness of memory deficits has been recognized as a common phenomenon in Alzheimer's disease (AD) and research is now increasingly focusing on awareness in groups at risk for future dementia. This study aimed to determine whether levels of awareness differ among healthy elderly people and patients with subjective cognitive decline (SCD), amnestic and non-amnestic subtypes of mild cognitive impairment (aMCI, naMCI), Alzheimer's disease (AD) and Parkinson's disease (PD), to explore correlates of awareness and to establish frequencies of memory over- and underestimation within each diagnostic group. Methods: 756 consecutive outpatients of a memory clinic and 211 healthy controls underwent thorough neuropsychological testing. Impairment of awareness was measured as the difference between subjective memory appraisals (16-item questionnaire on current memory-related problems in everyday life) and objective memory performance (15-item delayed recall task). Subgroups of over- and underestimators were classified using percentile ranks of controls. Results: At group level, awareness significantly decreased along the naMCI→aMCI→AD continuum, with naMCI patients showing a tendency towards overestimation of memory dysfunction. PD patients showed accurate self-appraisals as long as memory function was largely unaffected. However, there was a considerable between-group overlap in awareness scores. Furthermore, different correlates of awareness were observed depending on the diagnostic group. In general, unawareness seems to be associated with decreased cognitive performance in various domains (especially memory), higher age and lower levels of depression and self-reported functional impairment. Conclusion: Impaired awareness is an important symptom in aMCI. Yet, given the considerable variability in awareness scores, longitudinal studies are required to evaluate their predictive power.
Neurotrophins in Allergic Airway Dysfunction

Abstract: Neurotrophins such as nerve growth factor (NGF) and brain‐derived neurotrophic factor (BDNF) are potent mediators of neuronal plasticity in the adult. There is increasing evidence that they regulate a variety of immune functions as well. Thus, neurotrophins are candidate molecules for neuroimmune interactions in allergic bronchial asthma, where elevated neurotrophin levels have been reported. In a mouse model of allergic airway inflammation we have identified macrophages and lymphocytes as additional cellular sources of NGF and BDNF in the inflamed lung. There was an unusual time course of BDNF in bronchoalveolar lavage fluid. BDNF levels peaked 1 week after the last allergen challenge, and did not correlate with the time course of the inflammatory response. In a series of experiments using blocking anti‐NGF and anti‐BDNF antibodies, we have shown that NGF specifically enhances inflammation and the allergic early‐phase response. In contrast, BDNF influenced chronic airway obstruction and local neuronal hyperreactivity without affecting inflammation. Using transgenic mice overexpressing NGF in the airway epithelium, we have confirmed the data obtained from anti‐NGF experiments. Allergen‐challenged NGF overexpressors displayed a markedly augmented airway inflammation, early‐phase response, and sensory irritation compared to wild‐type mice. Studies with p75‐NTR (−/−) knockout mice showed that these NGF effects are at least in part mediated by the low‐affinity neurotrophin receptor. Thus, our experiments suggest that NGF and BDNF have a profound, but differential impact on allergic airway dysfunction.
