Results: Linear mixed models did not yield significant effects for statin or CoQ supplement use on changes in mental status, learning and memory, psychomotor speed, and cognitive flexibility.

Cyber Risk Propagation and Optimal Selection of Cybersecurity Controls for Complex Cyberphysical Systems.

The increasingly witnessed integration of information technology with operational technology leads to the formation of Cyber-Physical Systems (CPSs) that intertwine physical and cyber components and connect to each other to form systems-of-systems. This interconnection enables the offering of functionality beyond the combined offering of each individual component, but at the same time increases the cyber risk of the overall system, as such risk propagates between and aggregates at component systems. The complexity of the resulting systems-of-systems in many cases leads to difficulty in analyzing cyber risk.

Identifying and Analyzing Dependencies in and among Complex Cyber Physical Systems.

Contemporary Critical Infrastructures (CIs), such as the power grid, comprise cyber physical systems that are tightly coupled, to form a complex system of interconnected components with interacting dependencies. Modelling methodologies have been suggested as proper tools to provide better insight into the dependencies and behavioural characteristics of these complex systems. In order to facilitate the study of interconnections in and among critical infrastructures, and to provide a clear view of the interdependencies among their cyber and physical components, this paper proposes a novel method, based on a graphical model called Modified Dependency Structure Matrix (MDSM).

The cognitive effects of anticholinergic drugs on apolipoprotein ε4 carriers and noncarriers in the Wisconsin Registry for Alzheimer's Prevention study.

Objectives: The purpose of the study was to test the hypothesis that anticholinergic drug exposure is associated with cognitive decline in the Wisconsin Registry for Alzheimer's Prevention (WRAP) study. Secondary aims were to assess if the effects of anticholinergic drugs on different domains of cognitive functioning varied for the entire sample and by apolipoprotein ε4 status.

Methods: The WRAP study includes a sample of 1,573 subjects who self-reported medication use and were administered several cognitive tests four times over a decade.

The effects of proton pump inhibitors on neuropsychological functioning.

Objective: The current study investigated the effects of proton pump inhibitor use and apolipoprotein ε4 carrier status on changes in neuropsychological functioning in healthy adults with familial risk factors for dementia.

Methods: As part of the Wisconsin Registry for Alzheimer's Prevention study, 1,573 subjects were administered questionnaires on their medical history, gave blood samples, and were administered neuropsychological assessments during four visits over a 10-15 year period. Linear mixed models assessed if non-users, subjects who stopped, started, or consistently used proton pump inhibitors differed in changes in working memory, verbal memory, psychomotor speed, and cognitive flexibility.

Examination of the Phenomenology of the Ibogaine Treatment Experience: Role of Altered States of Consciousness and Psychedelic Experiences.

Psychedelic drugs have historically been used for ritualistic purposes and to help individuals gain insight. Ibogaine, a naturally occurring psychoactive substance, has been reported to have anti-addictive properties that aid in the treatment of substance use disorders. An online survey obtained retrospective data from individuals who used ibogaine in the past.

Factors associated with non-reimbursable activity on an inpatient pediatric consultation-liaison service.

The aim of this study was to identify factors contributing to clinician time spent in non-reimbursable activity on an inpatient pediatric consultation-liaison (C-L) service. A retrospective study was conducted using inpatient C-L service data on 1,246 consecutive referrals. For this patient population, the strongest predictor of level of non-reimbursable clinical activity was illness chronicity and the number of contacts with C-L service clinicians during their hospital stay.

The challenge for security and privacy services in distributed health settings.

The health care sector is quickly exploiting Information and Communication Technologies towards the provision of e-health services. According to recent surveys, one of the most severe restraining factors for the proliferation of e-health is the (lack of) security measures required to assure both service providers and patients that their relationship and transactions will be carried out in privacy, correctly, and timely. A large number of individuals are not willing to engage in e-health (or are only participating at a reduced level) simply because they do not trust the e-health service providers' sites and the underlying information and communication technologies to be secure enough.

High level security policies for health care establishments.

Health Care Establishments (HCE) are today highly dependent upon Information and Communications Technologies (ICT). This increasing reliance upon ICT has stressed the need to foster security in Healthcare Information Systems (HIS). Security policies may have a significant contribution to this effort, but they could become the cause of portability and interoperability problems.

Overview on security standards for Healthcare information systems.

The intense need for Healthcare information exchange has revealed a lack of interoperability of systems and applications. Security controls, usually based on proprietary methods and techniques, aggravate the current situation. However, timely development of HIS security standards may improve the interoperability and enable the integration of systems.
