The Delirium Observation Screening Scale Recognizes Delirium Early after Cardiac Surgery

Abstract: Background: Ddelirium or acute confusion is a temporary mental disorder which occurs frequently among hospitalized elderly patients. Patients who undergo cardiac surgery have an increased risk of developing delirium. Prevention or early recognition of delirium is essential. The Delirium Observation Screening (DOS) scale was developed to facilitate early recognition of delirium by nurses' observations during routine clinical care.Aim: The aim of this study was to validate the DOS scale in accordance with the diagnosis of the psychiatrist, using the DSM-IV criteria as the gold standard.Methods: In this observational study, the DOS scale was used to assess whether 112 patients who underwent elective cardiac surgery had developed a postoperative delirium. The psychiatrist was consulted to confirm or refute the diagnosis delirium. Wilcoxon's Rank Sum Test was utilized to compare patients with and without delirium on duration of hospital stay. A Receiver Operating Characteristic Curve of the DOS scale was const...

Dark tourism and voyeurism: tourist arrested for “spying” in Iran

Abstract: Purpose – The purpose of this paper is to propose voyeurism as one possible lens to analyse the experiential nature of dark tourism in places of socio‐political danger, thus expanding psychoanalytic understandings of those who travel to a “dark” place.Design/methodology/approach – Freud's and Lacan's theories on voyeurism are used to examine the desire to travel to and gaze upon something that is (socially constructed as) forbidden, such as a place that is portrayed as being hostile to international tourists. A qualitative and critical analysis approach is employed to examine one tourist's experience of travelling to Iran and being imprisoned as a result of taking a photograph of what he thought was a sunrise but also pictured pylons near an electrical plant.Findings – The authors' analysis of the experiences of this tourist in Iran reveals that tourism, in its widest sense, can be experienced as “dark” through the consumption and performance of danger. This finding moves beyond the examination of dark to...

Toward Fast and Quantitative Modification of Large Gold Nanoparticles by Thiolated DNA: Scaling of Nanoscale Forces, Kinetics, and the Need for Thiol Reduction

Abstract: We have recently reported on the fast and quantitative adsorption of DNA to 13 nm gold nanoparticles (AuNPs) at pH 3. This is in contrast to most traditional methods at neutral pH, where the adsorption is both slow and requires high excess of DNA. Direct application of our protocol to large particles in many cases did not result in particles that are stable at high (0.3 M) salt, and high excess of DNA was still required for the formation of stable particles. In this work, we investigate the reasons for this limitation on the basis of kinetics and colloidal stability. On the basis of our investigation, fast and quantitative modification of large AuNPs is still possible, either by working at high particle concentration, or by using sonication. As we have shown that fast quantitative modification of large particles is possible, the preparation step of reduction and purification of the thiolated DNA becomes the rate limiting step in the whole AuNP-DNA conjugate protocol. However, we show that this step is unn...

Reference values for isometric muscle force among workers for the Netherlands: A comparison of reference values

Abstract: Muscle force is important for daily life and sports and can be measured with a handheld dynamometer. Reference values are employed to quantify a subject’s muscle force. It is not unambiguous whether reference values can be generalized to other populations. Objectives in this study were; first to confirm the reliability of the utilization of hand-held dynamometers for isometric strength measurement; second to determine reference values for a population of Dutch workers; third to compare these values with those of a USA population. 462 Healthy working subjects (259 male, 203 female) were included in this study. Their age ranged from 20 to 60 years with a mean (sd) of 41 (11) years. Muscle force values from elbow flexion and extension, knee flexion and extension, and shoulder abduction were measured with the break method using a MicroFet 2 hand-held dynamometer. Reliability was analyzed by calculating ICC’s and limits of agreement. Muscle force expressed in Newton, means, and confidence intervals were determined for males and females in age groups ranging from twenty to sixty years old. Regression equations and explained variances were calculated from weight, height, age, and gender. The mean values and 95% CI were compared to the results from other studies. Reliability was good; the ICC ranged between 0.83 to 0.94. The explained variance ranged from 0.25 to 0.51. Comparison of data for the Dutch population mean muscle force values with those from the USA revealed important differences between muscle force reference values for the American and Dutch populations. Muscle force measurements demonstrate a sound reliability. Reference values and regressions equations are made available for the Dutch population. Comparison with other studies indicates that reference values differ between countries.
