AIM: To validate the European Health Literacy Survey Questionnaire (HLS-EU-Q47) in people with type 2 diabetes mellitus. BACKGROUND: The HLS-EU-Q47 latent variable is outlined in a framework with four cognitive domains integrated in three health domains, implying 12 theoretically defined subscales. Valid and reliable health literacy measurers are crucial to effectively adapt health communication and education to individuals and groups of patients. DESIGN: Cross-sectional study applying confirmatory latent trait analyses...

In a reaction, determination of an optimal path with a high reaction rate (or a low free energy barrier) is important for the study of the reaction mechanism. This is a complicated problem that involves lots of degrees of freedom. For simple models, one can build an initial path in the collective variable space by the interpolation method first and then update the whole path constantly in the optimization. However, such interpolation method could be risky in the high dimensional space for large molecules. On the path, steric clashes between neighboring atoms could cause extremely high energy barriers and thus fail the optimization...

Comorbidity challenges the notion of mental disorders as discrete categories. An increasing body of literature shows that symptoms cut across traditional diagnostic boundaries and interact in shaping the latent structure of psychopathology. Using exploratory and confirmatory factor analysis, we reveal the latent sources of covariation among nine measures of psychopathological functioning in a population-based sample of 13024 Finnish twins and their siblings. By implementing unidimensional, multidimensional, second-order, and bifactor models, we illustrate the relationships between observed variables, specific, and general latent factors...

OBJECTIVES: The objective of this study was to examine multidimensional determinants of the caregiving burden among Chinese male caregivers of older family members in Hong Kong. Based on a modified stress process model, this study explored how background and contextual factors (demographic characteristics and mental health status of caregivers, caregiving-related factors, and support and services), primary stressors (degree of care dependency and special care needs), and secondary stressors (self-efficacy and gender role conflict) might affect the caregiving burden among male caregivers...

Pedestrian detection in thermal infrared images poses unique challenges because of the low resolution and noisy nature of the image. Here we propose a mid-level attribute in the form of the multidimensional template, or tensor, using Local Steering Kernel (LSK) as low-level descriptors for detecting pedestrians in far infrared images. LSK is specifically designed to deal with intrinsic image noise and pixel level uncertainty by capturing local image geometry succinctly instead of collecting local orientation statistics (e...

BACKGROUND: Health information systems are innovative products designed to improve the delivery of effective healthcare, but they are also vulnerable to breaches of information security, including unauthorised access, use, disclosure, disruption, modification or destruction, and duplication of passwords. Greater openness and multi-connectedness between heterogeneous stakeholders within health networks increase the security risk. OBJECTIVE: The focus of this research was on the indirect effects of management support (MS) on user compliance behaviour (UCB) towards information security policies (ISPs) among health professionals in selected Malaysian public hospitals...

Structured alphabets of DNA and RNA in their matrix form of representations are connected with Walsh functions and a new type of systems of multidimensional numbers. This type generalizes systems of complex numbers and hypercomplex numbers, which serve as the basis of mathematical natural sciences and many technologies. The new systems of multi-dimensional numbers have interesting mathematical properties and are called in a general case as "systems of united-hypercomplex numbers" (or briefly "U-hypercomplex numbers")...

The ability of all cells to set and regulate their size is a fundamental aspect of cellular physiology. It has been known for sometime but not widely so, that size stability in animal cells is dependent upon the operation of the sodium pump, through the so-called pump-leak mechanism (Tosteson and Hoffman, 1960). Impermeant molecules in cells establish an unstable osmotic condition, the Donnan effect, which is counteracted by the operation of the sodium pump, creating an asymmetry in the distribution of Na(+) and K(+) staving off water inundation...

Medication adherence in patients with chronic heart failure is recognized as one of the major issues in the management of this pathology. Demographic status and socioeconomic conditions in African countries may have an impact on chronic heart failure treatment adherence. We conducted a cross-sectional study of patients with heart failure treated in the center of heart failure in the Department of Cardiology at the IBN ROCHD University Hospital (Morocco) from September 2014 to January 2015. The extent of medication adherence was based on a questionary: CARDIA-Questionary...

Adolescents with Sluggish Cognitive Tempo (SCT) exhibit symptoms of slowness, mental confusion, excessive daydreaming, low motivation, and drowsiness/sleepiness. Although many symptoms of SCT reflect internalizing states, no study has evaluated the clinical utility of self-report of SCT in an attention-deficit/hyperactivity disorder (ADHD) sample. Furthermore, it remains unclear whether SCT is best conceptualized as a unidimensional or multidimensional construct. In a sample of 262 adolescents comprehensively diagnosed with ADHD, the present study used adolescent- and parent reports of SCT to evaluate the predictive utility of a general SCT factor from a bifactor modeling approach compared the utility of three specific SCT factors (slow, sleepy, and daydreamer) for predicting academic impairment and internalizing psychopathology...

Sarcopenia, the progressive and generalized loss of muscle mass and strength/function, is a major health issue in older adults, given its high prevalence and the burdensome clinical ramifications. The absence of a unified operational definition for sarcopenia has hampered its full appreciation by healthcare providers, researchers and policy-makers. At the same time, this unresolved debate and the complexity of musculoskeletal aging pose major challenges to the identification of clinically meaningful biomarkers...

This study reports part of a long-term program to help students improve scientific reasoning using higher-order cognitive tasks set in the discipline of cell biology. This skill was assessed using problems requiring the construction of valid conclusions drawn from authentic research data. We report here efforts to confirm the hypothesis that data interpretation is a complex, multifaceted exercise. Confirmation was obtained using a statistical treatment showing that various such problems rank students differently-each contains a unique set of cognitive challenges...

Cuticular hydrocarbons (CHC) have been successfully used in the field of forensic entomology for identifying and ageing forensically important blowfly species, primarily in the larval stages. However in older scenes where all other entomological evidence is no longer present, Calliphoridae puparial cases can often be all that remains and therefore being able to establish the age could give an indication of the PMI. This paper examined the CHCs present in the lipid wax layer of insects, to determine the age of the cases over a period of nine months...

BACKGROUND: Older adults in residential settings frequently suffer from functional decline, mental illness, and social isolation, which make them more vulnerable to spiritual distress. However, empirical evidence of the interrelationships between physiopsychosocial variables and spiritual well-being are still lacking, limiting the application of the biopsychosocial-spiritual model in institutional healthcare practice. AIMS: To explain the mechanisms by which these variables are linked, this cross-sectional study tested a causal model of predictors of spiritual well-being among 377 institutionalized older adults with disability using a structural equation modeling approach...

Trade-offs maintain diversity and structure communities along environmental gradients. Theory indicates that if covariance among functional traits sets a limit on the number of viable trait combinations in a given environment, then communities with strong multidimensional trait constraints should exhibit low species diversity. We tested this prediction in winter annual plant assemblages along an aridity gradient using multilevel structural equation modelling. Univariate and multivariate functional diversity measures were poorly explained by aridity, and were surprisingly poor predictors of community richness...

BACKGROUND: Previous research has proposed that persons in need of palliative care often have a loss of functions and roles that affects social and existential self-image. Moreover, these individuals also commonly suffer from complex multisymptoms. This, together with the situation of facing an impending death, can lead to a loss of dignity. Therefore, supporting these persons' dignity is a crucial challenge for professional nurses. The 'Dignity Care Intervention' addresses the multidimensionality of dignity by identifying patients' dignity-related concerns and suggests care actions to address them...

REVIEW

The poverty trap concept strongly influences current research and policy on poverty alleviation. Financial or technological inputs intended to "push" the rural poor out of a poverty trap have had many successes but have also failed unexpectedly with serious ecological and social consequences that can reinforce poverty. Resilience thinking can help to (i) understand how these failures emerge from the complex relationships between humans and the ecosystems on which they depend and (ii) navigate diverse poverty alleviation strategies, such as transformative change, that may instead be required...
