Objectives:
While early diagnosis of younger-onset dementia (YOD) is crucial in terms of accessing appropriate services and future planning, diagnostic delays are common. This study aims to identify predictors of delay to diagnosis in a large sample of people with YOD and to investigate the impact of a specialist YOD service on this time to diagnosis.
Design:A retrospective cross-sectional study.
Setting:The inpatient unit of a tertiary neuropsychiatry service in metropolitan Victoria, Australia.
Participants:People diagnosed with a YOD.
Measurements and methods:We investigated the following predictors using general linear modeling: demographics including sex and location, age at onset, dementia type, cognition, psychiatric diagnosis, and number of services consulted with prior to diagnosis.
Results:A total of 242 inpatients were included. The mean time to diagnosis was 3.4 years. Significant predictors of delay included younger age at onset, dementia type other than Alzheimer’s disease (AD) and behavioral-variant frontotemporal dementia (bvFTD), and increased number of services consulted. These predictors individually led to an increased diagnostic delay of approximately 19 days, 5 months, and 6 months, respectively. A specialized YOD service reduced time to diagnosis by 12 months.
Conclusion:We found that younger age at onset, having a dementia which was not the most commonly occurring AD or bvFTD, and increasing number of services were significant predictors of diagnostic delay. A novel result was that a specialist YOD service may decrease diagnostic delay, highlighting the importance of such as service in reducing time to diagnosis as well as providing post-diagnostic support.

Nanostructured carbon materials, especially activated carbon, carbon nanotubes, and graphene, have been widely studied for supercapacitor applications. To maximize the efficacy of these materials for electrochemical energy storage, a detailed understanding of the relationship between the nanostructure of these materials and their performance as supercapacitors is required. A fundamental structural parameter obtained from the Raman spectra of these materials, the in-plane correlation length or nanocrystalline domain size, is found to correlate with the electrochemical capacitance, regardless of other morphological features. This correlation for a common nanostructural characteristic is believed to be the first result of its kind to span several distinct nanostructured carbon morphologies, including graphene–carbon nanotubes hybrid materials, and may allow more effective nanoscale engineering of supercapacitor electrode materials.

Graphene and carbon nanotubes (CNTs) are fascinating materials, both scientifically and technologically, due to their exceptional properties and potential use in applications ranging from high-frequency electronics to energy storage devices. This manuscript introduces a hybrid structure consisting of graphitic foliates grown along the length of aligned multiwalled CNTs. The foliate density and layer thickness vary as a function of deposition conditions, and a model is proposed for their nucleation and growth. The hybrid structures were studied using electron microscopy and Raman spectroscopy. The foliates consist of edges that approach the dimensions of graphene and provide enhanced charge storage capacity. Electrochemical impedance spectroscopy indicated that the weight-specific capacitance for the graphenated CNTs was 5.4× that of similar CNTs without the graphitic foliates. Pulsed charge injection measurements demonstrated a 7.3× increase in capacitance per unit area. These data suggest that this unique structure integrates the high surface charge density of the graphene edges with the high longitudinal conductivity of the CNTs and may have significant impact in charge storage and related applications.

Electrochemical double layer capacitors, also referred to as supercapacitors, are a promising technology in the field of energy storage. Carbon nanotube (CNT)-based supercapacitors are particularly interesting because of CNTs' high surface area and conductivity. CNT supercapacitors can potentially be used in hybrid electric vehicles due to their higher power density. Comparing energy storage systems that store energy in different ways, such as batteries, fuel cells, supercapacitors, and flywheels, requires that an appropriate set of performance data be collected. A Ragone plot is a log-log plot of a device's energy density versus power density, giving insight into its operational range. A method to obtain Ragone plots for CNT-based supercapacitors in a three-terminal electrochemical cell was adapted from a technique to test commercial capacitors for electric vehicles. Ragone plots for different types of as-grown CNT electrodes in different electrolytes are presented, along with the procedural details of this new method to obtain electrode-specific energy and power densities. Additionally, a theoretical weight calculation for a carbon nanotube film was derived and validated with a direct weight measurement of a CNT film. This weight was used in the specific energy and power densities for the Ragone plot.

The Early Iron Age enclosures and associated sites on Sutton Common on the western edge of the Humberhead Levels contain an exceptional variety of archaeological data of importance not only to the region but for the study of later prehistory in the British Isles. Few other later prehistoric British sites outside the East Anglian fens and the Somerset Levels have thus far produced the quantity and quality of organically preserved archaeological materials that have been found, despite the small scale of the investigations to date. The excavations have provided an opportunity to integrate a variety of environmental analyses, of wood, pollen, beetles, waterlogged and carbonised plant remains, and of soil micromorphology, to address archaeological questions about the character, use, and environment of this Early Iron Age marsh fort. The site is comprised of a timber palisaded enclosure and a succeeding multivallate enclosure linked to a smaller enclosure by a timber alignment across a palaeochannel, with associated finds ranging in date from the Middle Bronze Age to the Roman and medieval periods. Among the four adjacent archaeological sites is an Early Mesolithic occupation site, also with organic preservation, and there is a Late Neolithic site beneath the large enclosure. Desiccation throughout the common is leading to the damage and loss of wooden and organic remains. It is hoped that the publication of these results, of investigations between 1987 and 1993, will lead to a fuller investigation taking place.

The aim of this study was to determine the incidence of selected blood types in a homogeneously diagnosed group of manic-depressive patients as compared to the incidence of these blood types in a control group and in reported figures for the general population. This interest in the blood characteristics of manic-depressive subjects was stimulated by the finding of a relatively high incidence of active duodenal ulcer or medically and roentgenographically confirmed duodenal ulcer histories in manic-depressive patients (16 per cent.) (12) as contrasted with the reported incidence of duodenal ulcer in the general population (5-10 per cent.) (4). The specific association of duodenal ulcer with O-type blood has been reported by several investigators (1, 2). Although the reported relationships between blood type and specific disease entities have been critically questioned in a recent review, the reviewer concluded that the evidence “tends to suggest that a relationship between duodenal ulcer and group O blood actually exists” (10). The known and suspected relationships of blood types with various disease processes have been summarized by established investigators in the field of blood grouping and classification (14).
