Informal caregiver and healthcare professional perspectives on dementia and nutrition.

Background: Persons living with dementia and informal caregivers are at a higher risk for malnutrition. Most caregivers are not experts at identifying nutritional complications of dementia. Therefore, we aimed to identify nutrition knowledge and challenges related to feeding and caring for persons with dementia to develop a meaningful intervention.

Self-prescribed and other informal care provided by physicians: scope, correlations and implications.

Background: While it is generally acknowledged that self-prescribing among physicians poses some risk, research finds such behaviour to be common and in certain cases accepted by the medical community. Largely absent from the literature is knowledge about other activities doctors perform for their own medical care or for the informal treatment of family and friends. This study examined the variety, frequency and association of behaviours doctors report providing informally.

Silicidation of silicon nanowires by platinum.

The solid-state reaction between platinum and silicon nanowires grown by the vapor-liquid-solid technique was studied. The reaction product PtSi is an attractive candidate for contacts to p-type silicon nanowires due to the low barrier height of PtSi contacts to p-type Si in the planar geometry, and the formation of PtSi was the motivation for our study. Silicidation was carried out by annealing Pt on Si nanowires from 250 to 700 degrees C, and the reaction products were characterized by transmission electron microscopy.

On the Szaszian argument.

The Szaszian argument claims that psychiatry is a rhetorical enterprise aimed at providing justification for involuntary treatment. Such treatment, the argument holds, is just when provided to those suffering from demonstrable brain lesions, but it is unjust in cases of "mental illness" because such "illnesses" lack objective histopathology and are therefore fictional. It is here argued that this distinction is irrelevant to the morality or immorality of involuntary treatment, since such treatment inevitably rests on a subjective determination of competency or dangerousness, which is not rendered substantially more objective by the criterion of histopathology.

Accuracy of referring psychiatric diagnosis on a consultation-liaison service.

The authors determined the accuracy of the initial psychiatric diagnosis of primary medical providers requesting psychiatric consultation in a general medical inpatient setting. A retrospective review of 346 consecutive psychiatric consultations was conducted in which the initial diagnostic impression of primary medical providers was compared with the final psychiatric diagnosis. Accuracy rates for cognitive disorders, substance use disorders, and depressive disorders were 100%, 88.
