Kettle test efficacy in predicting cognitive and functional outcomes in geriatric rehabilitation

Background/aim: Limited research has been available to support the use of the Kettle Test in a subacute rehabilitation setting with patients diagnosed with a variety of medical conditions. The Kettle Test is an occupation based performance measure designed to detect cognitive processes and function. The aim of this research was to measure the correlation between three cognitive tests, the Mini-Mental State Examination (MMSE), Cognitive Functional Independence Measure (Cognitive FIM) and the Kettle Test. Secondly, to assess the efficacy of these tests in predicting functional outcomes via the motor subscale of the Functional Independence Measure (mFIM). Methods: A prospective single-centre cohort study in a subacute rehabilitation setting of 97 patients. Results: Correlation coefficients between the tests were statistically significant and moderately strong, with values ranging from 0.593 to _0.589. Significant positive correlations were seen between admission MMSE, Cognitive FIM and the mFIM and significant negative correlations between Kettle Test scores and the mFIM. The Kettle Test score had a stronger relationship with mFIM (r = _0.40; P \u3c 0.01) compared to the Cognitive FIM (r = 0.33; P \u3c 0.01) and MMSE (r = 0.26; P \u3c 0.05). The Kettle Test variance is significantly associated with the MMSE and Cognitive FIM at admission and discharge measures. Modelling identified that age and gender significantly contribute to this relationship. When adjusted for age and gender the MMSE and Cognitive FIM both explained the 47% of the variance at discharge. Conclusion: There were statistically significant inter-test correlations between the MMSE, Cognitive FIM and Kettle Test. The Kettle Test had the strongest relationship to patient functional outcomes

The life-history of basalt ground stone tools from early urban domestic contexts: A chronicle from the EBA III of Tell es-Safi/Gath, Israel

Recent archaeological excavations at the early urban settlement of Tell es-Safi/Gath, Israel present the opportunity to reconstruct the life-history of basalt ground stone artefacts of an early urban domestic neighbourhood. Tell es-Safi/Gath is a multi-period site located on the border between the Judean foothills and the southern coastal plain of central Israel. Survey and excavations over the last two decades demonstrated that it was a major urban centre for the region during the Early Bronze Age (EBA) III. At the eastern end of the site, a neighbourhood of commoner residences (some perhaps associated with mercantile activities) have been exposed. This paper describes and analyses the basalt ground stone tools found in association with this domestic neighbourhood. It seeks to establish the nature of production, distribution, consumption, and discard associated with ground stone tools within a domestic context. The study involved several forms of analysis including typology, macroscopic observations, and excavation data. It is suggested that basalt sources from the northeastern regions of the southern Levant were exploited for the small-scale production of basalt artefacts by non-specialised craftsmen. These commodities were then transported in more or less finished form to Tell es-Safi/Gath where they were further redistributed or sold to the settlement residents. The residents of the Tell es-Safi/Gath neighbourhood utilised the basalt artefacts for traditionally domestic tasks, and ultimately intentionally discarded or recycled them in a few depositional contexts. In summary, this paper presents a unique investigation into the life-history of basalt ground stone artefacts discovered in the EB III occupation levels of Tell es-Safi/Gath. It further demonstrates the potential of ground stone tools for understanding the behaviour and daily life of non-elite people

Validation of a low-cost virtual reality system for training street-crossing. A comparative study in healthy, neglected and non-neglected stroke individuals

Unilateral spatial neglect is a common consequence of stroke that directly affects the performance of activities of daily living. This impairment is traditionally assessed with paper-and-pencil tests that can lack correspondence to real life and are easily compensated. Virtual reality can immerse patients in more ecological scenarios, thus providing therapists with new tools to assess and train the effects of this impairment in simulated real tasks. This paper presents the clinical validation and convergent validity of a low-cost virtual reality system for training street-crossing in stroke patients with and without neglect. The performance of neglect patients was significantly worse than the performance of non-neglect and healthy participants. In addition, several correlations between the scores in the system and in the traditional scales were detected.This study was funded in part by Ministerio de Educacion y Ciencia Spain, Projects Consolider-C (SEJ2006-14301/PSIC), "CIBER of Physiopathology of Obesity and Nutrition, an initiative of ISCIII" and the Excellence Research Program PROMETEO (Generalitat Valenciana.

Perceived wellbeing of patients one year post stroke in general practice - recommendations for quality aftercare

<p>Abstract</p> <p>Background</p> <p>Annually, 41,000 people in the Netherlands have strokes. This has multiple physical and psychosocial consequences. Most patients return home after discharge from hospital. Quality aftercare by general practitioners is important to support patients at home. The purpose of this study is to examine the wellbeing of patients who returned home immediately after discharge from hospital, one year post stroke, in comparison with the general Dutch population of the same age and to determine factors that could influence wellbeing.</p> <p>Methods</p> <p>All the stroke patients from the Department of Neurology, Martini Hospital Groningen in the period November 2006 to October 2007 were included. People aged under 65 years or with haemorrhaging were excluded. All the patients (N = 57) were interviewed at home using the following questionnaires: Barthel Index, SF-36, HADS, CSI and a questionnaire about their way of life.</p> <p>Results</p> <p>31% of the patients in this study experienced a decrease in functional status after one year. Nevertheless, there was no significant difference between the median Barthel Index value at discharge from hospital and one year post stroke. ADL independence correlated with a better quality of life. The health-related quality of life was high. Stroke patients have almost the same quality of life as the 'average' Dutch elderly population. Where patients can no longer fully participate in society, their perceived quality of life is also lower. In this study there is an indication of a high prevalence of depression and anxiety disorders in stroke patients. This negatively affects the quality of life a year after stroke. Although caregiver strain was low for the partners of stroke patients, a reduced quality of life is correlated to greater burden.</p> <p>Conclusions</p> <p>This study provides valuable insight into the wellbeing of patients living at home one year post stroke. Physical functioning and quality of life are comparable to the general population of the same age, but improvements in mental functioning can be envisaged. In addition, more attention should be paid to maintaining the patients' activities. The wellbeing of these stroke patients could be increased further if greater attention is paid to these aspects of life. This seems to be applicable to general practice.</p

Yo Ho, Yo Ho, A Pirate's Life for Me: The Maritime Culture of the Sea Peoples

An anthropological approach to a culture extrapolates social structures, traditions, and general organising principles of that culture from the careful observation of patterns of behaviour as described in case studies. In the absence of a living culture to record, archaeologists extrapolate this information from behaviour reconstructed from spatially determined patterns in the deposition of material remains and from patterns found in the general organizing principles of historically documented cultures, using arguments based on analogy. This contribution builds on our previous research on the “Sea Peoples” as a piratical culture in order to apply an anthropological approach to understanding the cultural identities of the various tribal groups involved in maritime activities at the end of the Bronze Age who are popularly known as the “Sea Peoples”, and place this within the broader context of the current discussions on the transition between the Late Bronze and Early Iron Age in the Mediterranean

Pirates of the Crete-Aegean: Migration, Mobility, and Post-Palatial Realities at the End of the Bronze Age

Our recent research has used historical accounts of piracy to briefly examine pirate leadership, pirate culture and social organization, feasting activities, and studies of pirate geography to propose an interpretive framework for understanding the migration of the Sea Peoples as, inter alia, pirate tribes who plundered some of the great centers of the Mediterranean at the end of the Bronze Age. We suggest that as Mycenaean control over trade routes collapsed with the destruction and/or eventual abandonment of the Mycenaean palaces, Crete became particularly vulnerable to piracy, because of certain geographical and topographical features that characterized its coastlines. Unless defended, rocky coastlines, natural harbors, promontories, and river valleys were susceptible to piratical activity, as we shall discuss. Historical records indicate that piracy resulted in a desolation of coastlines, as coastal settlements and coastal plains might be attacked at night, with villages burnt and pillaged, and fields devastated. Inhabitants of such areas were motivated to move to defensible places further inland. Such abandonment and movement to defensible areas characterized early Iron Age Cretan settlements, such as Karphi, Kavousi, Kephala-Vasiliki, Chalasmenos, Monastiraki, Thronos-Kephala, and many others, which were relatively inaccessible from the surrounding landscape and represent only a fraction of the total. Our paper considers the role of piracy at the end of the Bronze Age in influencing migration, new realities, social practices, and changes in the cultural environment and social organization of post-palatial Crete. We also explore the idea that just as certain areas of Crete were geographically suitable for seeking refuge from pirates, other sites in Crete became similarly suitable hideouts for pirates
