BACKGROUND: Prevalence estimates of HIV-associated neurocognitive disorders (HAND) may be inflated. Estimates are determined via cohort studies in which participants may apply suboptimal effort on neurocognitive testing, thereby inflating estimates. Additionally, fluctuating HAND severity over time may be related to inconsistent effort. To address these hypotheses, we characterized effort in the Multicenter AIDS Cohort Study. METHODS: After neurocognitive testing, 935 participants (525 HIV-, 410 HIV+) completed the Visual Analogue Effort Scale (VAES), rating their effort from 0-100%...

OBJECTIVE: Hypertrophic cardiomyopathy (HCM) as a common genetic heart disease characterized by ventricular hypertrophy and myocardial fibrosis is significantly associated with a higher risk of fatal ventricular arrhythmic events (VAEs). We aimed to assess the interval between the peak and the end of the electrocardiographic T wave (Tp-e) and Tp-e/corrected QT (QTc) ratio as candidate markers of ventricular arrhythmias in patients with HCM. METHODS: In this single-center, prospective study, a total of 66 patients with HCM and 88 controls were enrolled...

Classical cadherin transmembrane cell-cell adhesion proteins play essential roles in tissue morphogenesis and in mediating tissue integrity. Cadherin ectodomains from opposing cells interact to form load-bearing trans dimers that mechanically couple cells. Cell-cell adhesion is believed to be strengthened by cis clustering of cadherins on the same cell surface. This review summarizes biophysical studies of the structure, interaction kinetics and biomechanics of classical cadherin ectodomains. We first discuss the structure and equilibrium binding kinetics of classical cadherin trans and cis dimers...

REVIEW
M Chance Spalding, Michael W Cripps, Christian T Minshall
The National Healthcare Safety Network's new classification characterizes all adverse ventilator-associated events (VAE) into a tiered system designed to shift the focus away from ventilator-associated pneumonia as the only important cause or morbidity in ventilated patients. This new surveillance definition of VAE eliminates subjectivity by using clearly defined criteria and facilitates the automated collection of data. This allows for easier comparison and analysis of factors affecting rates of VAE. Numerous studies have been published that demonstrate its clinical application...

In the present work we present an investigation of the negative ion-molecule chemistry of the anaesthetics isoflurane, ISOF, and enflurane, ENF, in an ion mobility spectrometry/mass spectrometry (IMS/MS), in both air and nitrogen. Hexachloroethane (HCE) was introduced in both air and nitrogen to produce Cl(-) as a reactant ion. This study was undertaken owing to uncertainties in the chemical processes, which lead to the cluster ions reported in other work (Eiceman et al. Anal. Chem. 61, 1093-1099, 1). In particular for ISOF the product ion observed was ISOF...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a serious long-term lung disease in which the airflow from the lungs is progressively reduced. By 2030, COPD will become the third cause of mortality and seventh cause of morbidity worldwide. With advances in technology and mobile communications, significant progress in the mobile health (mHealth) sector has been recently observed. Mobile phones with app capabilities (smartphones) are now considered as potential media for the self-management of certain types of diseases such as asthma, cancer, COPD, or cardiovascular diseases...

People objectify others by viewing them as less warm, competent, moral, and human (Heflick & Goldenberg, 2009, J. Exp. Soc. Psychol., 45, 598; Vaes, Paladino, & Puvia, 2011, Eur. J. Soc. Psychol., 41, 774). In two studies, we examined whether the objectified share this view of themselves, internalizing their objectification. In Study 1 (N = 114), we examined sexual objectification, and in Study 2 (N = 62), we examined workplace objectification. Consistent across both studies, we found that objectification resulted in participants seeing themselves as less warm, competent, moral (Study 2 only), and lacking in human nature and human uniqueness...

The occurrence and general applicability of the CD4:8 ratio as a surrogate predictor of mortality among the oldest old have only been tested in a few longitudinal studies. Here, the predictive value of CD4:8 ratio for mortality with respect to the role of cytomegalovirus (CMV) infection was investigated. Using polychromatic flow cytometry, the CD4:8 ratio and T-cell subsets of 235 individuals aged 81.5 years or older were analyzed, and mortality data were collected after a mean period of 3.3 years. The hazard for all-cause mortality adjusted for age, comorbidity, and CMV serostatus increased 1...
