Objective:
As the world’s population ages, the number of people with dementia is expected to increase. In addition to progressive cognitive and functional deterioration, dementia comprises neuropsychiatric symptoms (NPS). NPS present significant management challenges based on their high frequency and disruptive nature. Against the prevailing guidelines, their treatment is often over-reliant on psychotropic drugs and other restrictive care approaches, frequently without a thorough assessment of underlying and potentially modifiable causes, such as over- and under-stimulating environments, untreated medical illnesses, drug interactions, or unidentified unmet needs. Consistent with the latter, the unmet needs model proposes that these neuropsychiatric phenomena are needs-driven and constitute indicators of identifiable unmet physical, psychological, emotional, or social needs. Despite this backdrop, few studies have investigated this association using standardized and replicable measures. In this context, the present study aims to put the unmet needs model into a practical context in order to disentangle the contribution of the unmet needs, assessed with the Camberwell Assessment of Need for the Elderly (CANE), to the presence of NPS.
Methods:A cross-sectional study was conducted. Participants were assessed with validated, accessible, and replicable measures, including the CANE interview and the Neuropsychiatric Inventory (NPI). Other variables collected included residents’ demographic characteristics, cognitive and functional impairment, and daily medication. Multivariate models were used to explore potential risk factors for NPS.
Results:Residents from four nursing homes entered the study. Results found that those with unmet needs assessed using CANE and those taking hypnotic/sedative medications had a higher risk of presenting at least one NPS, even after adjusting for other demographic and clinical-functional covariates.
Conclusion:Built on the main finding that unmet needs assessed with CANE can independently contribute to explaining the presence of NPS, a working model is proposed to find solutions for these symptoms based on uncovering unmet needs. The CANE, as a practical, low-cost, yet clinically relevant assessment of met and unmet needs may be used to signal need areas that can be useful for formulation and intervention purposes and may offer the first step towards individually-tailored non- pharmacological interventions for NPS.

Mild cognitive impairment (MCI) and Alzheimer’s Disease (AD) prevalence is expected to continue to increase, due to the population ageing. MCI and AD may impact patients’ decision-making capacities, which should be assessed through the disease course. These medical conditions can affect the various areas of decision-making capacity in different ways. Decision-making capacity in healthcare is particularly relevant among this population. Elders often suffer from multimorbidity and are frequently asked to make healthcare decisions, which can vary from consenting a routine diagnostic procedure to decide receiving highly risk treatments.
To assess this capacity in elders with MCI or AD, we developed the Healthcare Decision-Making Capacity Assessment Instrument (IACTD-CS - Instrumento de Avaliação da Capacidade de Tomada de Decisão em Cuidados de Saúde). This project is funded by Portuguese national funding agency for science, research and technology, FCT (SFRH/BD/139344/2018). IACTD-CS was developed based on Appelbaum and Grisso four abilities model, literature review and review of international assessment instruments. After IACTD-CS first version development, an exploratory study with focus groups was conducted. This study included focus groups with healthcare professionals and nursing homes’ professionals.
The focus groups main goals were: 1) understand the participants perception regarding healthcare decision-making capacity, 2) distinguish relevant aspects of decision-making, 3) discuss the abilities and items included in IACTD-CS and 4) identify new aspects or items to be added to IACTD-CS. A content analysis of the focus groups results, with resource to MAXQDA, was conducted afterwards. This exploratory study allowed to identify professionals’ perceptions on healthcare decision-making and its results were a significant contribute to IACTD-CS development. The proposed communication aims to describe the methodology used and present the results of content analysis.

Nowadays, the use of virtual reality/virtual acoustics (VR/VA) in archaeology for rendering lost buildings is an important topic in the cultural heritage field. Moreover, the addition of additional senses apart from the sight increases the feeling of immersion in virtual environments. The aim of this paper is to show the interaction work developed in a VA system, based on Unity and FMOD, the graphical and acoustical reconstruction of an ancient building and the development of a VR goggles with headphones to render 3D audio and video interactively. This system has been implemented to render auralizations in a binaural system and has been applied to the renderization of an old and lost theatre in València (Spain). The first building of theatre was built in the 16th century, and was rebuilt several times until the 18th century. The auralization of several theatrical excerpts of different Spanish authors of that time is also presented. The integrated system has been subjectively evaluated, obtaining very satisfactory results.

Objective
Among cognitive reserve markers, educational attainment is the most widely studied, with several studies establishing a strong association with risk of dementia. However, it has not yet been fully examined in delirium. This study aims to analyse the relationship between educational attainment and delirium.
MethodsThe study included elderly hospitalised patients admitted (≥48 h) into an intermediate care unit (IMCU) of Intensive Care Medicine Service. Exclusion criteria were as follows: Glasgow Coma Scale (total≤11), blindness/deafness, inability to communicate or to speak Portuguese. The European Portuguese Version of the Confusion Assessment Method (CAM) was used for delirium assessment.
ResultsThe final sample (n=157) had a mean age of 78.8 (SD=7.6) the majority being female (52.2%), married (51.5%) and with low educational level (49%). According to CAM, 21% of the patients had delirium. The delirium group presented the fewest years of education (median 1 vs. 4), with statistical significance (p=0.003). Delirium was more frequent among male patients [odds ratio (OR) 0.32; 95% confidence interval (CI) 0.12–0.86; p=0.023], as well as those patients with lower education (OR 0.76; 95% CI 0.62–0.95; p=0.016), and with respiratory disease (OR 3.35; 95% CI 1.20–9.33; p=0.020), after controlling for age and medication.
ConclusionSimilar to previous studies, these findings point to a negative correlation between education and delirium. This study appears as an attempt to contribute to the knowledge about the role of cognitive reserve in risk of delirium, particularly because is the first one that has been carried out in an IMCU, with lower educated elderly patients. Further studies are needed to clarify this relationship considering other markers (e.g. cognitive activities), which can contribute to the definition of preventive strategies.

Ca2MnO4 nanoparticles were prepared by the Pechini method and acid treated to extract Ca2+ ions. Structural, morphological and spectroscopic analyses by XRD, SEM/EDX, TEM/EDS and Raman revealed the formation of an amorphous outer layer at the particles surface with a preserved inner crystalline bulk. Thanks to the outer layer, which is electrochemically active, the acid-treated compounds showed capacity up to 150 Ah/kg. The crystalline bulk improved cycling stability, allowing reaching capacity retention up to 70% after 30 cycles.

Background:
The Confusion Assessment Method (CAM) is the most widely used delirium screening instrument. The aim of this study was to evaluate the reliability and validity of the European Portuguese version of CAM.
Methods:The sample included elderly patients (≥65 years), admitted for at least 48 h, into two intermediate care units (ICMU) of Intensive Medicine and Surgical Services in a university hospital. Exclusion criteria were: score ≤11 on the Glasgow Coma Scale (GCS), blindness/deafness, inability to communicate and to speak Portuguese. For concurrent validity, a blinded assessment was conducted by a psychiatrist (DSM-IV-TR, as a reference standard) and by a trained researcher (CAM). This instrument was also compared with other cognitive measures to evaluate convergent validity. Inter-rater reliability was also assessed.
Results:In this sample (n = 208), 25% (n = 53) of the patients had delirium, according to DSM-IV-TR. Using this reference standard, the CAM had a moderate sensitivity of 79% and an excellent specificity of 99%. The positive predictive value was 95%, indicating a strong ability to confirm delirium with a positive test result, and the negative predictive value was lower (93%). Good convergent validity was also found, in particular with Mini-Mental State Examination (MMSE) (rs = −0.676; p ≤0.01) and Digit Span Test (DST) forward (rs = −0.605; p ≤0.01), as well as a high inter-rater reliability (diagnostic k = 1.00; single items’ k between 0.65 and 1.00).
Conclusion:Robust results on concurrent and convergent validity and good reliability were achieved. This version was shown to be a valid and reliable instrument for delirium detection in elderly patients hospitalized in intermediate care units.

Background:
Mental health professionals are frequently involved in mental capacity determinations. However, there is a lack of specific measures and well-defined procedures for these evaluations. The main purpose of this paper is to provide a review of financial and testamentary capacity evaluation procedures, including not only the traditional neuropsychological and functional assessment but also the more recently developed forensic assessment instruments (FAIs), which have been developed to provide a specialized answer to legal systems regarding civil competencies.
Methods:Here the main guidelines, papers, and other references are reviewed in order to achieve a complete and comprehensive selection of instruments used in the assessment of financial and testamentary capacity.
Results:Although some specific measures for financial abilities have been developed recently, the same is not true for testamentary capacity. Here are presented several instruments or methodologies for assessing financial and testamentary capacity, including neuropsychological assessment, functional assessment scales, performance based functional assessment instruments, and specific FAIs.
Conclusions:FAIs are the only specific instruments intended to provide a specific and direct answer to the assessment of financial capacity based on legal systems. Considering the need to move from a diagnostic to a functional approach in financial and testamentary capacity evaluations, it is essential to consider both general functional examination as well as cognitive functioning.

A Digits Rapid Automatized Naming (RAN) test and a Colors and Shapes Rapid Alternating Stimulus (RAS) test were administered to 904 Portuguese, normally achieving children (ages 7 to 15), in order to examine these tests scores developmental course. The results showed that the two tests have slightly different developmental trajectories. In addition, the two tests associations with a large number of neuropsychological measures were determined in three age groups (7-9 years, n = 301; 10-12 years, n = 299; 13-15 years, n = 304). The neuropsychological measures addressed attention/executive functions, motor behavior, verbal memory, visual memory and language. The results indicated that each one of the rapid naming tests brings into play not entirely coincident processes. Although, they converge in terms of their associations with language and attention measures, Colors and Shapes RAS test is more demanding in cognitive and linguistic terms. In addition, while Digits RAN test has little in common with short-term memory, Colors and Shapes RAS test relates moderately with short-term memory, due to the increased demands in terms of effort, access and retrieval of the phonological labels that correspond to the different stimuli categories. The need to differentiate between the two rapid naming tests is supported.

The technique of sperm-mediated gene transfer (SMGT) can be used to delivery exogenous DNA into the oocyte. However, it has low repeatability and produces inconsistent results. In order to optimize this technique, it is necessary to study the mechanism by which DNA enters the sperm cell and integrates in the sperm genome. Furthermore, studies must focus in the maintenance of sperm cell viability and function. The aim of this study was to evaluate different SMGT protocols of sperm electroporation or capacitation (CaI) aiming to maintain sperm viability in the production of bovine embryos in vitro. Frozen–thawed semen was divided in two experimental groups (electroporation or CaI) and one control group (non-treated cells). For the electroporation method, five different voltages (100, 500, 750, 1000 or 1500 V) with 25 μF capacitance were used. For CaI treatment, combinations of two CaI concentrations (250 nM or 500 nM), two incubation periods of sperm cells with CaI (1 or 5 min) and two incubation periods that mimicked time of sperm cell interaction with exogenous DNA molecules (1 or 2 h) were evaluated. According to our data, electroporation and CaI treatments do not prevent sperm penetration and oocyte fertilization and can be an alternative method to achieve satisfactory DNA delivery in SMGT protocols.

The Montreal Cognitive Assessment (MoCA) is a brief instrument developed for the screening of milder forms of cognitive impairment, having surpassed the well-known limitations of the MMSE. The aim of the present study was to validate the MoCA as well as its short version, which was proposed by the NINDS-CSN VCI Harmonization Standards for screening Vascular Dementia (VaD) patients. The results, based on a homogeneous sample of 34 VaD patients, indicate that the MoCA is a psychometrically valid and reliable instrument for cognitive screening in VaD patients, showing excellent discriminant validity. Both the full and short versions of the MoCA had excellent diagnostic accuracy in discriminating VaD patients, exhibiting an area under curve (AUC) higher than the MMSE [AUC(MoCA full version) = .950; 95% IC = .868–.988; AUC(MoCA short version) = .936; 95% IC = .849–.981; AUC(MMSE) = .860; 95% IC = .754–.932]. With a cutoff below 17 on the MoCA full version and 8 on the short version, the results for sensitivity, specificity, positive and negative predictive values, and classification accuracy were superior compared to the MMSE. In conclusion, both versions of the MoCA are valid, reliable, sensitive and accurate screening instruments for VaD patients. (JINS, 2012, 18, 1–10)

Huntington's disease (HD) is a genetic neurodegenerative disorder affecting the basal ganglia. These subcortical structures are particularly important for motor functions, response selection and implicit learning. In the current study, we have assessed prodromal and symptomatic HD participants with an implicit contextual learning task that is not based on motor learning, but on a purely visual implicit learning mechanism. We used an implicit contextual learning task in which subjects need to locate a target among several distractors. In half of the trials, the positions of the distractors and target stimuli were repeated. By memorizing this contextual information, attention can be guided faster to the target stimulus. Nine symptomatic HD participants, 16 prodromal HD participants and 22 control subjects were included. We found that the responses of the control subjects were faster for the repeated trials than for the new trials, indicating that their visual search was facilitated when repeated contextual information was present. In contrast, no difference in response times between the repeated and new trials was found for the symptomatic and prodromal HD participants. The results of the current study indicate that both prodromal and symptomatic HD participants are impaired on an implicit contextual learning task. (JINS, 2012, 18, 1–8)

The Montreal Cognitive Assessment (MoCA) is a brief instrument developed for the screening of milder forms of cognitive impairment. The present study aims to assess the construct related validity of the MoCA through the establishment of the factorial, convergent, and discriminant related validities, and the reliability of data. In a Portuguese sample of 830 participants, several models were tested using Confirmatory Factor Analysis. Although all tested models showed a good fit, the six-factor model based on the conceptual model proposed by the MoCA's authors showed a significantly better fit. The results allowed us to establish the factorial, convergent, and discriminant validity of this six-dimensional structure. An overall psychometric adequacy of the items, and a good reliability were also found. This study contributes to overcome an important gap in the construct related validity of this instrument. The present findings corroborate the six-dimensional structure of the MoCA and provide good evidence of the construct related validity. The MoCA has proved to be an appropriate measure for cognitive screening taking into account different cognitive domains, which will enable clinicians and researchers to use this test and its six latent dimensions to achieve a better understanding of the individuals’ cognitive profile.

Background: In response to the global challenges of population aging in Portugal, it is crucial to improve research, education and clinical training in old age in order to meet the growing demands placed on psychogeriatric care services.
Methods: An overview is provided on the status of old age psychology and psychiatry as part of the multidisciplinary care delivery system for the elderly in Portugal. Available educational offerings and clinical training in geriatric mental health at both undergraduate and postgraduate level are described, as well as primary research associations and initiatives within Portugal.
Results: Important issues raised include the need for more educational and clinical training programs for specialists, a broader commitment to aging research and the need to increase interest in working with older adults among students across disciplines. The recent movement towards multidisciplinary work conducted by researchers, psychiatrists, psychologist and other health professionals in Portugal points to the urgent need for specialist education for all health professionals working in geriatrics. This educational initiative must focus not only on the transmission of knowledge on aging-related topics, but also on the training of specific skills and competencies. Improving geriatric mental health service delivery and connecting research with clinical practice constitute other significant steps forward.
Conclusions: An effective intervention in psychogeriatrics should involve a strategy with the participation of a multidimensional network that includes the commitment of researchers, educators, clinicians, health policy-makers and older adults. Several recommendations to improve late life mental health care are presented.

The geographical distribution of the Ananatuba phase has been extended to the eastern coast of Marajó by the discovery of J-26: Castanheira on the right bank of the middle Rio Camará. Two stratigraphic cuts were excavated, and the pottery obtained was classified into the types established by Meggers and Evans (1957). The resulting seriated sequence shows trends of ceramic change parallel to theirs and a similar intrusion of Mangueiras phase sherds in the upper levels of the deposit. Interdigitation of the J-26 levels into the seriated sequence for the Ananatuba phase shows the new site to occupy a relatively late position, supporting the earlier inference of expansion from the north coast toward the southeast during the history of the phase. A charcoal sample obtained from Cut 1, Level 40-50 cm., and correlating with the appearance of Mangueiras phase sherds in the refuse, gave the date of 980 B.C. ± 200 (SI-385), which places the initial occupation of Marajó by pottery-making groups within the Formative period.
