RESUMO

By approaching the concept of Natural Intelligence a new path may be open in a variety of theoretical and applied problems on social emotions. There is no doubt that intelligence emerges as a biological/informational phenomenon, although paradoxically a consistent elaboration of that concept has been missing. Regarding emotions, they have been keeping an unclear status, being often restricted to the anthropological or to ethological approaches closer to the behaviorist paradigm. Herein we propose a different track, centered in the life cycle advancement. The life cycle in its integrity becomes the nucleus of natural intelligence's informational processes, including the consistent expression of emotions along the maximization of fitness occasions. In human societies, the overall 'economy' of social emotions is manifest, showing up in the conspicuous interplay between bonding processes and different classes of social emotions. The essential link between natural intelligence, emotions, and the life cycle of individuals may harmonize with current progresses - and blind spots - of artificial intelligence fields such as 'sentiment analysis.'

RESUMO

Background: Stroke represents the second preventable cause of death after cardiovascular disease and the third global cause of disability. In countries where national registries of the clinical quality of stroke care have been established, the publication and sharing of the collected data have led to an improvement in the quality of care and survival of patients. However, information on rehabilitation processes and outcomes is often lacking, and predictors of functional outcomes remain poorly explored. This paper describes a multicenter study protocol to implement a Stroke rehabilitation Registry, mainly based on a multidimensional assessment proposed by the Italian Society of Physical and Rehabilitation Medicine (PMIC2020), in a pilot Italian cohort of stroke survivors undergoing post-acute inpatient rehabilitation, to provide a systematic assessment of processes and outcomes and develop data-driven prediction models of functional outcomes. Methods: All patients with a diagnosis of ischemic or haemorrhagic stroke confirmed by clinical assessment, admitted to intensive rehabilitation units within 30 days from the acute event, aged 18+, and providing informed consent will be enrolled. Measures will be taken at admission (T0), at discharge (T1), and at follow-up, 3 months (T2) and 6 months (T3) after the stroke. Assessment variables include anamnestic data, clinical and nursing complexity information and measures of body structures and function, activity and participation (PMIC2020), rehabilitation interventions, adverse events and discharge data. The modified Barthel Index will be our primary outcome. In addition to classical biostatistical analysis, learning algorithms will be cross-validated to achieve data-driven prognosis prediction models. Conclusions: This study will test the feasibility of a stroke rehabilitation registry in the Italian health context and provide a systematic assessment of processes and outcomes for quality assessment and benchmarking. By the development of data-driven prediction models in stroke rehabilitation, this study will pave the way for the development of decision support tools for patient-oriented therapy planning and rehabilitation outcomes maximization. Clinical tial registration: The registration on ClinicalTrials.gov is ongoing and under review. The identification number will be provided when the review process will be completed.

RESUMO

Introduction: Due to their impact on healthcare systems, the sustainability and optimization of high-cost drugs is an issue of concern for several countries. Different strategies have been implemented such as centralized purchasing to optimize budgetary resources. However, there is still a need for a mechanism to optimize these drugs further. Methods: We conducted this prospective multicenter intervention study in five hospitals in the Andalusian Public Health System of Cádiz (Spain) between July 2019 and September 2021. We developed an online website (Farmastock) and implemented it to determine the availability of high-cost, low-use, and near-expiry medicines in each hospital. We used a simple analysis using operational variables to assess the project intervention's savings impact on managing these high-cost drugs. Results: The implementation of Farmastock in Cádiz resulted in savings of 675,757.52 € for the Andalusian Public Health System, with 238 medicines transferred out of the 373 available. Of these medicines offered, the most considerable percentage were medicines used for pathologies with high clinical instability and accounted for nearly 80% of the medicines optimized by the tool. Conclusions: Farmastock allowed the Andalusian Public Health System to make substantial financial savings by not making new purchases of high-cost drugs available in other centers of this health network that were not being used. Therefore, this tool is a very efficient measure to contribute to the sustainability of the APHS and could be implemented in more hospitals soon.

RESUMO

Gauging the social relationships of the elderly is a significant sociometric research subject and a deep biomedical concern-particularly after the COVID-19 pandemic. It is imperative for facultatives in primary care, for geriatric clinics, and for social care services. In this respect, this article explores the validity of an abbreviated version of the Sociotype Questionnaire (SOCQ), a tool previously developed by the authors for assessing the social relationships of the general population, now specifically addressed to the elderly population. The aim is to construct a 4-item dichotomous scale (SOCG-4) out of the 12 items of the original scale of the SOCQ, so that it can serve to discriminate among the patients in primary care and the geriatric clinic, helping the facultative to find those in need of social care or of psychosocial intervention. The population data have been obtained from a series of previous studies on social relationships in different segments of the elderly population (Ntotal = 915). The resulting abbreviated version of SOCG-4 was extracted by means of confirmatory factor analysis, with the congruence, validity, and relationship with the determinants as close to optimal. The significant correlations with SOCQ (0.82), UCLA (-0.55), Barthel (0.40), and other relevant tests are obtained. The test was also put to trial in a pilot study, being applied to 150 subjects via phone surveys, home visiting, and geriatric clinic-it becomes particularly useful for assessing the social relationships in geriatric clinic use. The 4-item Geriatric Sociotype scale (SOCG-4) appears as a valid measurement instrument for use in the clinic and in other social care instances.

RESUMO

The present work explores, from the vantage point of the sociotype, the dramatic acceleration of cultural change alongside the successive industrial revolutions, particularly in the ongoing information era. Developed within the genotype-phenotype-sociotype conceptual triad, the sociotype means the average social environment that is adaptively demanded by the "social brain" of each individual. For there is a regularity of social interaction, centered on social bonding and talking time, which has been developed as an adaptive trait, evolutionarily rooted, related to the substantial size increase of human groups. A quantitative approach to the sociotype basic traits shows fundamental competitive interrelationships taking place within an overall "attention economy." Approaching these figures via the Planckian Distribution Equation, they can be connected with many other competitive processes taking place in the biological, economic, and cultural realms. Concerning culture, the cognitive limits of the individual, which we consider commensurate with the sociotype general limitations, impose by themselves a strict boundary on the cultural items effectively handled by each individual, fostering the overall competition and decay. Further, the emergence of differentiated generations with ample discrepancy in styles of life, social aspirations, and dominant technologies would represent a systematic bias in the competition and replacement of cultural items. Intriguingly, the cultural acceleration detected in modern societies alongside the successive industrial revolutions, with an ostensible climax in the ongoing fourth industrial revolution -the information era- might be itself a paradoxical consequence of the sociotype's dynamic constancy.

RESUMO

BACKGROUND: Drug treatment for secondary prevention of cardiovascular disease is recommended by guidelines, but it is not always followed in real life. This study wanted to assess the size of this gap and its impact on mortality in subjects after a cardiovascular event (MACE). METHODS: Patients with any of MACE in the period from January 1st 2011 to December 31st 2013, and more than one year of follow-up were selected from population of the Valencian Community. Drugs for secondary prevention were antiplatelets, renin-angiotensin system blockers and statins. Assessment of treatment was performed one year after the initial event. Mortality risk was assessed using Cox by the number of drug classes (G0 no medication, G1 one, G2 two and G3 three drugs) adjusted by confounders. RESULTS: A total of 92,436 patients (62% men, mean age 72 years) of whom 60.5% presented with stroke, 30.6% with myocardial infarction and 8.9% with revascularization were included. Among them, 4.1% were G0, 20.2% G1, 32.9% G2 and 42.7% G3. A progressive decrease in mortality was observed in G1 (HR 0.83, CI 95% 0.73-0.95), G2 (HR 0.70, CI 95% 0.60-0.82) and G3 (HR 0.61, CI95% 0.51-0.74) vs. G0. In diabetic subgroup, significant reduction of risk was observed in the G2 (0.79, CI 95% 0.63-0.98) and G3 (0.72, CI9 5% 0.56-0.95), but not in G1 (0.97, CI 95% 0.80-1.17). CONCLUSION: A gap between guidelines and reality in the use of cardiovascular protecting drugs one year after the initial event still exists and it is largely related with all-cause late mortality.

RESUMO

The objective of this article is to show an experience of new practice as implemented by the management of a Department of Health. An organisational model is shown of sociosanitary coordination between the different levels of care and sectors, establishing synergies of the common social and health resources of the Clínico-Malvarrosa Department of Health (Valencia, Spain). After one year, five basic health councils have been set up in Primary Care and a Sociosanitary Coordination Commission composed of three subcommittees: 1) socio and health care, 2) associationism and hospital volunteering, and 3) community action and citizen participation. The proposed organisational structure has been consolidated, the actions carried out have been valued positively by the different agents involved. It has generated a network of social and health communication: interdepartmental, extra-departmental and out-of-hospital.

RESUMO

Resumen: Actualmente, la Medicina Basada en Evidencia tiene un papel fundamental en la toma de decisiones médicas, ya que intenta, a través de los métodos de la ciencia, justificar las diferentes alternativas que se le pueden ofrecer a un paciente. Para entender la evolución histórica de esta forma de practicar la medicina, es necesario revisar la contribución de uno de los principales participantes en este movimiento cultural: Archibald Leman Cochrane, quien ayudó a definir el marco teórico que ha permitido incorporar la ciencia a la práctica de la medicina. Su papel, al insistir en la necesidad de integrar la evidencia científica y conjuntarla con la experiencia clínica, constituyó un elemento fundamental y decisivo en el desarrollo de una nueva disciplina, la Medicina Basada en Evidencia.

RESUMO

BACKGROUND: Post-coma persons in a minimally conscious state (MCS) and with extensive motor impairment and lack of speech tend to be passive and isolated. OBJECTIVE: This study aimed to (a) further assess a technology-aided approach for fostering MCS participants' responding and stimulation control and (b) carry out a social validation check about the approach. METHODS: Eight MCS participants were exposed to the aforementioned approach according to an ABAB design. The technology included optic, pressure or touch microswitches to monitor eyelid, hand or finger responses and a computer system that allowed those responses to produce brief periods of positive stimulation during the B (intervention) phases of the study. Eighty-four university psychology students and 42 care and health professionals were involved in the social validation check. RESULTS: The MCS participants showed clear increases in their response frequencies, thus producing increases in their levels of environmental stimulation input, during the B phases of the study. The students and care and health professionals involved in the social validation check rated the technology-aided approach more positively than a control condition in which stimulation was automatically presented to the participants. CONCLUSIONS: A technology-aided approach to foster responding and stimulation control in MCS persons may be effective and socially desirable.

RESUMO

Intervention programs for people with acquired brain injury and extensive motor and communication impairment need to be diversified according to their characteristics and environment. These two studies assessed two technology-aided programs for supporting leisure (i.e., access to songs and videos) and communication (i.e., expressing needs and feelings and making requests) in six of those people. The three people participating in Study 1 did not possess speech but were able to understand spoken and written sentences. Their program presented leisure and communication options through written phrases appearing on the computer screen. The three people participating in Study 2 did not possess any speech and were unable to understand spoken or written language. Their program presented leisure and communication options through pictorial images. All participants relied on a simple microswitch response to enter the options and activate songs, videos, and communication messages. The data showed that the participants of both studies learned to use the program available to them and to engage in leisure and communication independently. The importance of using programs adapted to the participants and their environment was discussed.

RESUMO

These two studies extended the evidence on the use of technology-based intervention packages to promote adaptive behavior in persons with acquired brain injury and multiple disabilities. Study I involved five participants in a minimally conscious state who were provided with intervention packages based on specific arrangements of optic, tilt, or pressure microswitches (linked to preferred environmental stimuli) and eyelid, toe and finger responses. Study II involved three participants who were emerging from a minimally conscious state and were provided with intervention packages based on computer presentations of stimulus options (i.e., preferred stimuli, functional caregiver's procedures, and non-preferred stimuli) and pressure microswitches to choose among them. Intervention data of Study I showed that the participants acquired relatively high levels of microswitch responding (thus engaging widely with preferred environmental stimuli) and kept that responding consistent except for one case. Intervention data of Study II showed that the participants were active in choosing among preferred stimuli and positive caregivers' procedures, but generally abstained from non-preferred stimuli. The results were discussed in terms of the successful use of fairly new/infrequent microswitch-response arrangements (Study I) and the profitable inclusion of functional caregiver's procedures among the options available to choice (Study II).

RESUMO

OBJECTIVE: Evaluating a learning assessment procedure for monitoring progress with two post-coma adults with a diagnosis of vegetative state. METHOD: ABABCBCB and ABABCB designs were used for the two participants, with A representing baseline, B intervention and C control conditions. Participants' activation of an optic microswitch by eyelid closure produced stimulation during B phases. RESULTS: One participant increased responding during B phases and decreased it during the C condition, suggesting a non-reflective minimal level of consciousness. She showed P300 and mismatch negativity responses and scored at the vegetative level on the Coma Recovery Scale-Revised (CRS-R). The other participant increased responding during the initial B phases without decline during the first (viable) part of the C condition, suggesting a pre-conscious level. He showed indistinct P300 and mismatch negativity responses and vegetative-level scores on the CRS-R. CONCLUSION: Learning data seemed reconcilable with neurophysiological measures and more positive than CRS-R scores.

RESUMO

Post-coma persons in an apparent condition of vegetative state and pervasive motor impairment pose serious problems in terms of assessment and intervention options. A technology-based learning assessment procedure might serve for them as a diagnostic supplement with possible implications for rehabilitation intervention. The learning assessment procedure adopted in this study relied on hand-closure and eye-blinking responses and on microswitch technology to detect such responses and to present stimuli. Three participants were involved in the study. The technology consisted of a touch/pressure sensor fixed on the hand or an optic sensor mounted on an eyeglasses' frame, which were combined with a control system linked to stimulus sources. The study adopted an ABABCB sequence, in which A represented baseline periods, B intervention periods with stimuli contingent on the responses, and C a control condition with stimuli presented non-contingently. Data showed that the level of responding during the B phases was significantly higher than the levels observed during the A phases as well as the C phase for two of the three participants (i.e., indicating clear signs of learning by them). Learning might be deemed to represent basic levels of knowledge/consciousness. Thus, detecting signs of learning might help one revise a previous diagnosis of vegetative state with wide implications for rehabilitation perspectives.

RESUMO

OBJECTIVE: To evaluate the viability of technology-assisted learning setups for undertaking assessment and providing intervention to persons in vegetative state. METHOD: Study I investigated whether three persons with a diagnosis of vegetative state could associate eye blinking or hand closure responses with contingent, positive stimulation, thus increasing their frequencies (showing signs of learning). Study II extended the learning process (introducing a new response and new stimuli) for one of the participants of Study I. RESULTS: Two of the participants of Study I succeeded in increasing their responses, indicating signs of learning. Study II showed that the participant (one of the two succeeding in Study I) acquired a new response to access new stimuli and could alternate this response with the one acquired in Study I. CONCLUSION: Learning might represent a basic level of knowledge and consciousness. Detecting signs of learning might help modify a previous diagnosis of vegetative state and support intervention/rehabilitation efforts.

RESUMO

BACKGROUND AND AIMS: Although studies have shown that pollen addition and/or removal decreases floral longevity, less attention has been paid to the relationship between reproductive costs and floral longevity. In addition, the influence of reproductive costs on floral longevity responses to pollen addition and/or removal has not yet been evaluated. Here, the orchid Cohniella ascendens is used to answer the following questions. (a) Does experimental removal of flower buds in C. ascendens increase flower longevity? (b) Does pollen addition and/or removal decrease floral longevity, and does this response depend on plant reproductive resource status? METHODS: To study the effect of reproductive costs on floral longevity 21 plants were selected from which we removed 50 % of the developing flower buds on a marked inflorescence. Another 21 plants were not manipulated (controls). One month later, one of four flowers on each marked inflorescence received one of the following pollen manipulation treatments: control, pollinia removal, pollination without pollinia removal or pollination with pollinia removal. The response variable measured was the number of days each flower remained open (i.e. longevity). KEY RESULTS: The results showed significant flower bud removal and pollen manipulation effects on floral longevity; the interaction between these two factors was not significant. Flowers on inflorescences with previously removed flower buds remained open significantly longer than flowers on control inflorescences. On the other hand, pollinated flowers closed much faster than control and removed-pollinia flowers, the latter not closing significantly faster than control flowers, although this result was marginal. CONCLUSIONS: The results emphasize the strong relationship between floral longevity and pollination in orchids, as well as the influence of reproductive costs on the former.

RESUMO

The aim of this study is to assess the relationship among metabolic syndrome (MS), target organ damage (TOD) and established cardiovascular disease (CVD) in non-diabetic hypertensive elderly patients. ERIC-HTA is cross-sectional, multicentre study carried out in primary care, on hypertensive patients aged 55 or older. MS was defined by the NCEP-ATP III criteria, using body mass index (>28.8 kg/m(2)) instead of abdominal perimeter. In 8331 non-diabetic hypertensive patients (3663 men and 4668 women, mean age 67.7 years), the prevalence of MS was 32.6% (men: 29.0%; women: 36.8%). A linear association was observed between a greater number of components of MS and a greater prevalence of left ventricle hypertrophy (LVH) on the electrocardiogram (p<0.001), impaired kidney function (p<0.001) and established CVD (p = 0.001). In a multivariate model, MS in non-diabetic hypertensive patients was related to a greater prevalence of LVH (OR 1.31 [95% CI: 1.15-1.48]), impaired kidney function (OR 1.45 [95% CI: 1.29-1.63]) and established CVD (OR 1.22 [95% CI: 1.08-1.37]). This relationship persisted after stratifying by gender. In conclusion, in this elderly non-diabetic hypertensive population, the presence of MS was independently related to a greater prevalence of hypertensive TOD and established CVD, suggesting a role of MS as a cardiovascular risk marker in hypertension.

RESUMO

INTRODUCTION AND OBJECTIVES: Left ventricular hypertrophy (LVH) is the earliest manifestation of cardiac damage in hypertension. Its appearance is associated with a poor cardiovascular prognosis. The objectives of this study were to determine the prevalence of electrocardiographic LVH and to assess the epidemiological characteristics of hypertensive patients receiving primary care. PATIENTS AND METHOD: A cross-sectional multicenter study of hypertensive patients aged 55 years or more was carried out in a primary care setting. Blood pressure was measured using the standard method. Cardiovascular history was determined from medical records and LVH was assessed electrocardiographically using Cornell's criteria. RESULTS: In total, 15 798 patients (mean age 68.0 years, 55.3% women, and 30.4% with diabetes mellitus) were evaluated. Of these, 3207 (20.3%) had electrocardiographic signs of LVH. The prevalence was higher in males, diabetics, smokers, and patients with high blood pressure or renal or cardiovascular disease. Compared to patients without LVH, those with the condition were older, were more often male, and were more likely to have diabetes or renal or cardiovascular disease. Multivariate analysis showed that LVH was independently associated with advanced age, male gender, diabetes, smoking, poor blood pressure control, and the presence of cardiovascular or renal disease. Blood pressure control was poorer in patients with LVH than in those without it. CONCLUSIONS: The prevalence of electrocardiographic LVH is high, with affected patients being more likely to have diabetes or renal or cardiovascular disease. Moreover, blood pressure control is poor in these patients, and more aggressive pharmacological management is needed.

BACKGROUND AND OBJECTIVES: Epidemiological data on the incidence and prevalence of cardiovascular disease in chronic renal failure are scant The objective of the present study is to assess the relationship between renal function, measured by the estimated glomerular filtration rate, and the presence of early or established cardiovascular disease, in a population of hypertensives from primary care. PATIENTS AND METHODS: Cross-sectional, multicentre study carried out in primary care centres all over Spain. Hypertensive subjects, older than 55 years, were included. In all of them a structured interview including cardiovascular risk factors or disease was performed. Blood pressure was measured following a standard procedure, and serum biochemistry and an electrocardiogram were obtained. Renal function was estimated using the abbreviated MDRD (Modification of Diet in Renal Disease Study Group) equation. For each glomerular filtration rate stratum the odds ratio and 95% confidence interval (CI) of left ventricular hypertrophy or cardiovascular disease were calculated, adjusted by confounding variables. RESULTS: A total of 13 687 patients (mean age 68.1 years, women 55.4%, diabetics 30.6%, body mass index 28.6 kg/m2) were included. Of these, 26.4% had established cardiovascular diseases and 20.3% electrocardiographic left ventricular hypertrophy. The average serum creatinine was 1.01 mg/dl, creatinine clearance 70.0 ml/min, and glomerular filtration rate 74.0 ml/min per 1.73 m2. Thirty-three patients (0.24%) had glomerular filtration rate < 5 ml/min per 1.73 m2; 89 (0.65%) from 15 to 29; 3745 (27.36%) from 30 to 59; 7798 (56.97%) from 60 to 89; and 2019 (14.75%) higher than 89 ml/min per 1.73 m2. In a multiple regression analysis, after adjusting by age, sex, body mass index, diabetes, systolic and diastolic blood pressure, and smoking, a lower glomerular filtration rate was associated with a higher prevalence of left ventricular hypertrophy. Likewise, a reduction in the glomerular filtration rate was also associated with a higher prevalence of cardiovascular disease. CONCLUSIONS: In hypertensive patients from primary care, the prevalence of cardiovascular disease is inversely proportional to the level of renal function. Estimated glomerular filtration is easy to determine and complements evaluation of the hypertensive patient.

RESUMO

BACKGROUND AND OBJECTIVE: Stroke is a major cause of morbidity and mortality in hypertensive population. The aim of this study is to estimate the 10-year risk of a first stroke in Spanish hypertensive population using the Framingham scale. PATIENTS AND METHOD: Cross-sectional multicenter study in primary care environment, on hypertensive patients aged 55 or more (10 consecutive patients each physician). Blood pressure (BP) was measured according to standardized rules. Stroke and coronary risk were estimated using the Framingham scale. RESULTS: 16,129 patients (mean age 67.7 years; 57.1% women; 30.4% with diabetes mellitus; 26.6% with previous history of cardiovascular disease) were analyzed. 20.3% showed electrocardiographic left ventricular hypertrophy (more prevalent in males, diabetics, with systolic BP > or = 140 mmHg; p < 0.001). The goal of BP control was reached in 30.1% of non-diabetic patients and only in 5.9% of diabetics. The estimated 10-year risk of a first stroke (standard deviation) was estimated to be 19.9% (16.8), and the coronary risk 19.2% (14.0). While males had an estimated risk of coronary disease above the stroke risk, women had an estimated risk of a first stroke greater than the estimated risk of coronary disease. CONCLUSIONS: The estimated risk of stroke among Spanish hypertensive population is high, and the main risk factors (age, systolic BP, diabetes and left ventricular hypertrophy) tend to aggregate. In women estimated risk of stroke in greater than estimated coronary risk. The risk of stroke must be taken into account in the assessment and treatment of hypertensive patients.
