El paciente virtual: diseño y aplicación de una metodología activa basada en casos clínicos reales prácticos para impulsar el aprendizaje responsable y participativo de los estudiantes en un entorno colaborativo on-line

Premio a la Innovación en la Enseñanza 2012[ES] El centro de la enseñanza en la integración transdisciplinar no es, sin embargo, un tema o tópico seleccionado para este propósito, sino el campo de conocimiento biosanitario. El profesor proporciona una estructura o marco de oportunidades de aprendizaje, pero la integración la realiza el propio estudiante, basándose en las situaciones de alta fidelidad con el mundo real de la práctica profesional biosanitaria. Se ha definido como “un proceso individual de construcción de información y experiencia, filtradas a través de las percepciones únicas de cada uno de los individuos, pensamientos y sentimientos”. En este nivel, los límites entre las diferentes disciplinas han desaparecido y los estudiantes se centran enteramente en un nuevo constructo de conocimiento que transciende las disciplinas

Physiotherapeutic intervention to promote self-care: exploratory study on spanish caregivers of patients with dementia

[Abstract] The caregivers of dependent persons should benefit from social–health interventions that empower them. Physiotherapists can play an important role as facilitators of self-care learning by boosting the mind–body interaction. The aim of this study was to analyse the efficacy of a physiotherapeutic intervention centered on the promotion of self-care within a sample of caregivers, members of four Spanish Associations of Relative of Alzheimer's and other dementias. To fulfill the study goal, a pre-experimental study was developed with two different groups. Group 1 participated in four training sessions based exclusively on the communication of information and which addressed, among other aspects, the most frequent health problems in caregivers and the powerful role of self-care to face such problems. Group 2 received the same theoretical information as group 1, followed by 10 sessions of practical training in several concrete strategies of body–mind self-care. The results obtained support the usefulness of combining theoretical and practical training in mind–body strategies (relaxation, self-massage and stretching), as such combination managed to favor their implication to self-care and certain dimensions of psychological well-being, while attenuating the burden. Conversely, training based solely on theoretical approaches was not beneficial. Besides evidencing the usefulness of combining passive and active methodologies to favor self-care, the data provided calls for greater consideration of aspects close to philosophical perspectives like personal growth

The Influence of Nutrition in Alzheimer's Disease: Neuroinflammation and the Microbiome vs. Transmissible Prion

Alzheimer's disease (AD) is a primary, progressive, neurodegenerative disorder. Many risk factors for the development of AD have been investigated, including nutrition. Although it has been proven that nutrition plays a role in AD, the precise mechanisms through which nutrition exerts its influence remain undefined. The object of this study is to address this issue by elucidating some of the mechanisms through which nutrition interacts with AD. This work is a qualitative systematic bibliographic review of the current literature searchable on various available databases, including PubMed, Web of Science, and Google Scholar. Our evidence comprises 31 articles selected after a systematic search process. Patients suffering with AD present a characteristic microbiome that promotes changes in microglia generating a proinflammatory state. Many similarities exist between AD and prion diseases, both in terms of symptoms and in the molecular mechanisms of pathogenesis. Changes in the composition of the gut microbiome due to dietary habits could be one of the environmental factors affecting the development of AD; however, this is probably not the only factor. Similarly, the mechanism for self-propagation of beta-amyloid seen in AD is similar to that seen in prions

Involvement in self-care and psychological well-being of Spanish family caregivers of relatives with dementia

Observational study[Abstract] The provision of continuous care to a dependent person can lead to a lack of self-care by the caregiver themselves with corresponding low levels of well-being. This well-being has been analysed mostly from within the perspective of the hedonic tradition, with the development of personal growth often being overlooked. This study aims to increase the understanding of the connection between this type of psychological well-being and involvement in self-care activities, and to be a starting point for the determination of categories that may serve in the screening of potential participants in social-health interventions where it is being promoted. Taking the hypothesis of a probable positive connection between psychological well-being and involvement in self-care, an observational study was carried out on 45 caregivers of relatives with dementia. In those caregivers showing greater dedication to self-care, a higher score was obtained on the well-being scales connected to personal significance and positive emotions and experiences. These findings were further reinforced by the identification of other positive connections, the involvement in self-care and the six dimensions of wellness contemplated by Ryff. It is possible to envisage the existence of a virtuous circle in respect of the caregiver, whereby a greater involvement in self-care is related to a higher psychological well-being, which in turn is related to greater self-care, and so on

Las campañas de vacunación contra la poliomielitis en España en 1963

Two anti-poliomyelitic vaccination campaigns coexisted in 1963: the Salk vaccine used by the Compulsory Health Insurance and the pilot experience with the oral Sabin vaccine promoted by the Health General Office. This simultaneity of campaigns was due to the interest that both bodies had to control the Preventive Medicine in Spain. The Compulsory Sickness Insurance used the antipolio vaccine to promote itself socially in a time when the Basic Law on Social Security was being developed. Under these circumstances, the Health General Office allegedly brought forward its vaccine campaign by using a test of an innovative oral trivalent vaccine in the province of León, something which was hidden to the public. The Health General Office’s claim of competence in prevention and the need of a massive response to a voluntary vaccine led to a singular advertising campaign with old messages in innovative means of communication.En 1963 coexistieron en el tiempo dos campañas de vacunación antipoliomielítica: la llevada a cabo con vacuna Salk por el Seguro Obligatorio de Enfermedad y la experiencia piloto con vacuna oral Sabin que promovió la Dirección General de Sanidad. La simultaneidad obedecía a la pugna entre ambos organismos por controlar la Medicina Preventiva en España. El Seguro Obligatorio de Enfermedad utilizó la vacunación antipolio para promocionarse socialmente en unos momentos de gestación de la Ley de Bases de la Seguridad Social. En estas circunstancias, la Dirección General de Sanidad debió anticipar su campaña de vacunación mediante un ensayo de una novedosa vacuna trivalente oral en la provincia de León, aspectos que fueron ocultados a la población. La reivindicación de su competencia en la prevención y la necesidad de una respuesta masiva ante una vacunación voluntaria originaron una singular campaña publicitaria de añejos mensajes pero en novedosos medios de comunicación

Iron and physical activity: Bioavailability enhancers, properties of black pepper (Bioperine®) and potential applications

Producción CientíficaBlack pepper (Piper nigrum L.) has been employed in medicine (epilepsy, headaches, and diabetes), where its effects are mainly attributed to a nitrogen alkaloid called piperidine (1-(1-[1,3-benzodioxol-5-yl]-1-oxo-2,4 pentenyl) piperidine). Piperine co-administered with vitamins and minerals has improved its absorption. Therefore, this study aimed to describe the impact of the joint administration of iron (Fe) plus black pepper in physically active healthy individuals. Fe is a micronutrient that aids athletic performance by influencing the physiological functions involved in endurance sports by improving the transport, storage, and utilization of oxygen. Consequently, athletes have risk factors for Fe depletion, Fe deficiency, and eventually, anemia, mainly from mechanical hemolysis, gastrointestinal disturbances, and loss of Fe through excessive sweating. Declines in Fe stores have been reported to negatively alter physical capacities such as aerobic capacity, strength, and skeletal muscle recovery in elite athletes. Thus, there is a need to maintain Fe storage, even if Fe intake meets the recommended daily allowance (RDA), and Fe supplementation may be justified in physically active individuals, in states of Fe deficiency, with or without anemia. Females, in particular, should monitor their Fe hematological profile. The recommended oral Fe supplements are ferrous or ferric salts, sulfate, fumarate, and gluconate. These preparations constitute the first line of treatment; however, the high doses administered have gastrointestinal side effects that reduce tolerance and adherence to treatment. Thus, a strategy to counteract these adverse effects is to improve the bioavailability of Fe. Therefore, piperine may benefit the absorption of Fe through its bioavailability enhancement properties. Three research studies of Fe associated with black pepper have reported improvements in parameters related to the metabolism of Fe, without adverse effects. Although more research is needed, this could represent an advance in oral Fe supplementation for physically active individuals

The Efficacy and Effectiveness of Education for Preventing and Treating Non-Specific Low Back Pain in the Hispanic Cultural Setting: A Systematic Review

A systematic review was conducted to assess the efficacy and effectiveness of education programs to prevent and treat low back pain (LBP) in the Hispanic cultural setting. Electronic and manual searches identified 1148 unique references. Nine randomized clinical trials (RCTs) were included in this review. Methodological quality assessment and data extraction followed the recommendations from the Cochrane Back Pain Review Group. Education programs which were assessed focused on active management (3 studies), postural hygiene (7), exercise (4) and pain neurophysiology (1). Comparators were no intervention, usual care, exercise, other types of education, and different combinations of these procedures. Five RCTs had a low risk of bias. Results show that: (a) education programs in the school setting can transmit potentially useful knowledge for LBP prevention and (b) education programs for patients with LBP improve the outcomes of usual care, especially in terms of disability. Education on pain neurophysiology improves the results of education on exercise, and education on active management is more effective than “sham” education and education on postural hygiene. Future studies should assess the comparative or summatory effects of education on exercise, education on pain neurophysiology and education on active management, as well as explore their efficiency

Effects of Arginine Supplementation on Athletic Performance Based on Energy Metabolism: A Systematic Review and Meta-Analysis

Producción CientíficaNitric oxide related ergogenic aids such as arginine (Arg) have shown to impact positively on sport performance through several physiological and metabolic mechanisms. However, research results have shown to be controversial. The great differences regarding required metabolic pathways and physiological demands between aerobic and anaerobic sport disciplines could be the reasons. The aim of this systematic review and meta-analysis was to evaluate the effects of Arg supplementation on aerobic (≤VO2max) and anaerobic (>VO2max) performance. Likewise, to show the effective dose and timing of this supplementation. A structured search was carried out in accordance with PRISMA® (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and PICOS guidelines in PubMed/MEDLINE, Web of Science (WOS), and Scopus databases from inception to January 2020. Eighteen studies were included which compare Arg supplementation with placebo in an identical situation and testing its effects on aerobic and anaerobic performance tests. Trials analyzing supplementation with other supplements were removed and there was not athlete’s level, gender, ethnicity, or age filters. The performed meta-analysis included 15 studies and random effects model and pooled standardized mean differences (SMD) were used according to Hedges’ g. Results revealed that Arg supplementation could improve aerobic (SMD, 0.84; 95% CI, 0.12 to 1.56; magnitude of SMD (MSMD), large; I2, 89%; p = 0.02) and anaerobic (SMD, 0.24; 95% CI, 0.05 to 0.43; MSMD, small; I2, 0%; p = 0.01) performance tests. In conclusion, acute Arg supplementation protocols to improve aerobic and anaerobic performance should be adjusted to 0.15 g/kg of body weight ingested between 60–90 min before. Moreover, chronic Arg supplementation should include 1.5–2 g/day for 4–7 weeks in order to improve aerobic performance, and 10–12 g/day for 8 weeks to enhance anaerobic performance

25-Hydroxyvitamin D Serum Levels Linked to Single Nucleotide Polymorphisms (SNPs) (rs2228570, rs2282679, rs10741657) in Skeletal Muscle Aging in Institutionalized Elderly Men Not Supplemented with Vitamin D

Sarcopenia (Sp) is the loss of skeletal muscle mass associated with aging that results in an involution of muscle function and strength. Vitamin D deficiency is a common health problem worldwide, especially among the elderly, and hypovitaminosis D leads to musculoskeletal disorders. The aim of this study was to evaluate the impact and presence of a possible linkage between Single Nucleotide Polymorphisms (SNPs) CYP2R1 (rs10741657), GC (rs2282679), and VDR (rs2228570), serum 25-OH/D concentrations and the link with the degree of sarcopenia in 19 institutionalized elderly men not supplemented with vitamin D. Levels of 25-OH vitamin D were quantified with a commercial enzyme-linked immunosorbent assay kit and 3 SNPs were genotyped with KASPar assays. Significant differences in 25-OH/D concentration were determined between the bi-allelic combinations of rs228679 and rs228570. We detected statistically significant weak positive correlations between the AA (rs10741657 and rs228570) and TT (rs228679) and alleles and 25-OH/D and the probability of having higher 25-OH/D concentrations was 2- to 3-fold higher. However, the GG alleles of the 3 SNPs showed that the probability of having optimal 25-0H/D concentrations decreases by 32% for rs10741657, 38% for rs228679, and 74% for rs228570, showing a strong negative correlation between the degree of sarcopenia and 25-OH/D levels. Allelic variations in CYP2R1 (rs10741657), GC (rs2282679), and VDR (rs10741657) affect vitamin D levels and decisively influence the degree of sarcopenia in institutionalized elderly people.This research has been funded by the Chair of Knowledge and Innovation “Caja Rural de Soria” University of Valladolid Campus de Soria, Soria (Spain) in the call for funding research projects with project number SO-1-2020.
