Efectos de un programa de enseñanza de la danza tradicional en el aprendizaje motor de adultos mayores de un distrito de Lima, 2018

La población adulta mayor en el Perú se ha incrementado en estos últimos 30 años, sin embargo, la mayor cantidad se concentra en Lima Metropolitana. El envejecimiento produce un decrecimiento de las funciones cerebrales, es por eso la importancia de hacer estudios que permitan articular el nivel cognitivo y emocional, a través del manejo corporal, espacial y temporal. El propósito de esta investigación es analizar el efecto de un programa de enseñanza de la danza tradicional en el aprendizaje motor en adultos mayores de un distrito de Lima. Es una investigación con un enfoque cuantitativo, un diseño cuasi-experimental con un grupo experimental y otro grupo de control. La muestra fue de 27 participantes cuyas edades fluctuaron entre los 65 a 82 años, el grupo experimental estuvo constituido por 14 personas y el grupo control por 13 personas. El estudio se realizó a través de la enseñanza del baile Marinera Norteña en 15 sesiones con una duración de 2 horas. En esta investigación se demostró que el programa generó un efecto positivo y significativo en el aprendizaje motor en sus dimensiones: Coordinación viso-motora, coordinación audio-motora, manejo espacial y memoria motora. Se recomienda que se implementen programas en neuroeducación para la formación y capacitación a docentes y personas que trabajan con adultos mayores.The population of older people in Peru has increased in the last 30 years, however, most of it is concentrated in Metropolitan Lima. Aging produces a decrease in brain functions, so it is important to carry out studies that allow the articulation of the cognitive and emotional level, through body, spatial and temporal management. The purpose of this research is to analyze the effect of a traditional dance teaching program on motor learning in older adults in a district of Lima. It is a research with a quantitative approach with a quasi-experimental design with an experimental and control group. The sample consisted of 27 participants whose ages ranged from 65 to 82 years old, the experimental group consisted of 14 people and the control group 13 people. The study was carried out by teaching Marinera Norteña dance in 15 sessions of 2 hours’ duration. In this research, it was demonstrated that the program generated a positive and significant effect on motor learning in its dimensions: visual-motor coordination, audio motor coordination, spatial management and motor memory. It is recommended that neuroeducation programs be implemented for the education and training of teachers and people who work with older people

Methodology for the integral management of risks and insurance with a cooperative social management approach

The agricultural sector in Cuba constitutes a key sector in the objectives of sustainable development; with a high degree of vulnerability in a scenario plagued by threats and risks of various types. In this context, there are still serious difficulties in agricultural organizations to implement policies to manage the risks to which they are exposed. In the basic productive organizations, as in the case of the Credit and Services Cooperatives of Consolación del Sur municipality, the risks are not managed with an integral approach. The objective of this work was to design a methodology that allows to manage all the risks that these organizations face in an integral way; core aspect within cooperative social management. During the research, it was possible to contrast the results obtained from the study of different methodologies, adjusting and validating it for the integral management of risks in the Credit and Services Cooperatives, object of study, which was based on the guidelines of the ISO 31000/2018 standard on risk management and ISO 26000 on Corporate Social Responsibility, which have in common the focus of interest group, which is expressed in the efficient and effective fulfillment of the commitment of these organizations with the whole society. The main results consisted on the design and partial validation of the methodology in the Credit and Services Cooperatives "José Hernández León" of Consolación del Sur municipality, concluding that it is flexible and has the possibility to be applied to different companies in this sector

Intervention Program to Improve Grief-Related Symptoms in Caregivers of Patients Diagnosed With Dementia

The objectives of the present study were to adapt a grief intervention program to family caregivers of patients with dementia, and assess its effectiveness in improving the symptoms of grief and other health-related variables. The intervention was based on Shear and Bloom’s grief intervention program, with the necessary adaptations for use in the grieving process for a family member’s illness. A total of 52 family caregivers of individuals with dementia participated. They were evaluated using a battery of self-report measures assessing grief, overload, resilience, post-traumatic growth, experiential avoidance, health-related quality of life, and benefits of care. The results suggest that the program is effective in improving grief symptoms, caregiver burden, resilience, post-traumatic growth, and quality of life of family caregivers. It is necessary to create and implement interventions targeting caregivers’ feelings andmanifestations of ambiguous grief, because there is a lack of programs providing an efficient solution for the mental and physical health of caregivers, and because of the human and socioeconomic cost involved in neglecting this group

Estimating human leishmaniasis burden in Spain using the capture-recapture method, 2016-2017

Leishmaniasis is endemic and a mandatory reporting disease in Spain since 1982. However, between 1996 and 2014, surveillance on public health was decentralized and only some autonomous regions monitored the disease. The aim of this study is to estimate the incidence of leishmaniasis and to evaluate the extent of underreporting in Spain. A capture-recapture (CRC) study was conducted to calculate the incidence of human leishmaniasis using reports from the National Surveillance Network (RENAVE) and the Hospital Discharge Records of the National Health System (CMBD) for 2016 and 2017. During the study period, 802 cases were reported to RENAVE and there were 1,149 incident hospitalizations related to leishmaniasis. The estimated incidence rates through the CRC study were 0.79 per 100,000 inhabitants for visceral leishmaniasis (VL), 0.88 (cutaneous leishmaniasis (CL)) and 0.12 (mucocutaneous leishmaniasis (MCL)) in 2016 and 0.86 (VL), 1.04 (CL) and 0.12 (MCL) in 2017. An underreporting of 14.7-20.2% for VL and 50.4-55.1% for CL was found. The CRC method has helped us to assess the sensitivity and representativeness of leishmaniasis surveillance in Spain, being a useful tool to assess whether the generalization of leishmaniasis surveillance throughout the Spanish territory achieves a reduction in underreporting.S

Grief Experiences in Family Caregivers of Children with Autism Spectrum Disorder (ASD)

The main objective of this study was to analyse the experience of grief and feelings of loss in family caregivers of children diagnosed with autism spectrum disorder (ASD), as well as the perceived overload from taking on the primary caregiver role. Twenty family caregivers of children with ASD participated. The family members were assessed using an ad-hoc semi-structured interview that addressed the families' reactions to the diagnosis, implications for daily functioning, and concerns for the immediate and long-term future of their relatives with ASD. The results indicate that family caregivers of children with ASD endure intense and continuous sorrow and grief due to the impact that having and caring for a child with these characteristics has on all aspects of their lives. These data highlight the importance of creating support and intervention programmes and services focused on the feelings and manifestations of ambiguous grief that occur in these family members, in order to improve their well-being and quality of life and reduce caregiver role overload

On the use of discrete cosine transforms for multicarrier communications

In this correspondence, the conditions to use any kind of discrete cosine transform (DCT) for multicarrier data transmission are derived. The symmetric convolution-multiplication property of each DCT implies that when symmetric convolution is performed in the time domain, an element-by-element multiplication is performed in the corresponding discrete trigonometric domain. Therefore, appending symmetric redun-dancy (as prefix and suffix) into each data symbol to be transmitted, and also enforcing symmetry for the equivalent channel impulse response, the linear convolution performed in the transmission channel becomes a symmetric convolution in those samples of interest. Furthermore, the channel equalization can be carried out by means of a bank of scalars in the corresponding discrete cosine transform domain. The expressions for obtaining the value of each scalar corresponding to these one-tap per subcarrier equalizers are presented. This study is completed with several computer simulations in mobile broadband wireless communication scenarios, considering the presence of carrier frequency offset (CFO). The obtained results indicate that the proposed systems outperform the standardized ones based on the DFT

Influence of the menstrual cycle on physical and cognitive performance in eumenorrheic women.

Introduction: The female sexual hormones typical of the menstrual cycle not only have reproductive functions, they also influence other physiological systems and can affect sports and cognitive performance. The purpose of this study has been to evaluate different aspects such as body composition, endurance, muscle strength and some cognitive abilities at different stages of the menstrual cycle. Material and method: Eight young eumenorrheic women (age = 23.1 ± 4.4 years) with regular menstrual cycles participated in the study. A densitometry and bioimpedance test were performed to study body composition, a short-term visual memory test and a reaction time test to assess cognitive abilities, and muscle characteristics (thickness and stiffness of the anterior rectus and muscle strength) along with a progressive test to exhaustion were analyzed to assess performance during the mid-follicular (FF) and mid-luteal (FL) phases of the participants’ menstrual cycle. Results: During the follicular phase, the participants registered a greater total time (FF = 488.5 ± 93.18 s vs. FL = 468.6 ± 81.29 s; P = 0.015) and a lower initial heart rate (FF = 83.3 ± 10.23 PPM vs. FL = 92.9 ± 7.67 PPM; P = 0.034) in the progressive test to exhaustion. Regarding cognitive abilities, in the follicular phase, better results were obtained in reaction time both with the right hand (FF = 0.426 ± 0.082 s vs. FL = 0.453 ± 0.087 s; P = 0.036) and with the left hand (FF = 0.435 ± 0.096 s vs. FL = 0.466 ± 0.077 s; P = 0.034). On the other hand, a higher percentage of fat (FF = 27.3 ± 5.1% vs. FL = 27.9 ± 5.0%; P = 0.041) was found in the luteal phase. Conclusion: Performance in endurance and in cognitive test, such as reaction time was better in the Follicular Phase, while a higher percentage of fat was observed in the Luteal Phase. However, memory, strength and muscular characteristics were not affected by the hormonal fluctuations of the menstrual cycle.post-print337 K

Modelación de la cinética de reacción para la producción de polihidroxialcanoatos microbianos mediante Bacillus megaterium

Abstract. The production of poly(3-hydroxybutyrate) PHA by Bacillus. megaterium depends exclusively on the concentration of the carbon source (glucose), so it is proposed to use mathematical simulation models for the kinetics applied in the production of microbial polyhydroxyalkanoates. Bacteria can be isolated from Californian red worm humus, and a logistic model including an inhibition factor and a constant associated with cell maintenance is used for biomass growth. For product formation kinetics, the Leudeking-Piret model is proposed, where the product formation coefficient depends on cell growth and the constant associated with cell maintenance, both of which are determined by the fermentation pH, and correspond to associated and non-associated growth, respectively. The model for substrate consumption considers that cells metabolize substrate for growth, product synthesis and energy generation, as well as for internal pH control activities and exchange of cellular components. Kinetic equations are proposed to estimate experimental results of this case study based on the logistic, Leudeking-Piret and substrate consumption models, to determine the values of biomass and product yields, depending on the substrate used in the stoichiometry of PHA production. The next stage contemplates the application of UV-Vis spectrophotometry to estimate cell growth in Colony Forming Units (CFU) and its comparison with the McFarland scale to quantify equivalently the number of bacterial cells.La producción de poli-(3-hidroxibutirato) PHA por Bacillus. megaterium depende exclusivamente de la concentración de la fuente de carbono (glucosa), por lo que se propone utilizar modelos matemáticos de simulación para la cinética aplicada en la producción de polihidroxialcanoatos microbianos. Las bacterias pueden aislarse del humus de la lombriz roja californiana, y para el crecimiento de biomasa se utiliza un modelo logístico que incluye un factor de inhibición y una constante asociada al mantenimiento celular. En la cinética de formación de producto se propone el modelo de Leudeking-Piret, donde el coeficiente de formación del producto depende del crecimiento celular y la constante asociada al mantenimiento celular, ambas están determinadas por el pH de la fermentación, y corresponden al crecimiento asociado y no asociado respectivamente. El modelo para consumo de sustrato considera que las células lo metabolizan para crecimiento, síntesis de producto y generación de energía, así como para actividades de control de pH interno e intercambio de componentes celulares. Se plantea ecuaciones de cinética para estimar resultados experimentales de este caso de estudio basadas en los modelos logístico, de Leudeking-Piret y de consumo de sustrato, para determinar los valores de los rendimientos de biomasa y de producto, en función al sustrato utilizado en la estequiometria de la producción de PHA. La siguiente etapa contempla la aplicación de la espectrofotometría UV-Vis para estimar el crecimiento celular en Unidades Formadoras de Colonias (UFC) y su comparación con la escala de McFarland para cuantificar de forma equivalente el número de células bacterianas

Ebola virus disease 2014

Ebola virus disease was irst described in 1976 originating from the Ebola River in the Democratic Republic of Congo. Since then, Ebola virus has become an important public health threat in Africa, and now it is of great concern worldwide due to the recent outbreaks (9216 cases with 4555 deaths up to October 20th, 2014), and it is so far the largest and deadliest recorded in history. Five Ebola virus species have been identiied (including Zaire, Sudan, Ivory Coast, Reston, and Bundibugyo Ebola virus), and four of them have proved to be highly pathogenic for both human and non-human primates, causing viral hemorrhagic fever with case fatality rates of up to 90%, for which no approved therapeutics or vaccines are currently available. Ebola virus infections are characterized by immune suppression and a systemic inlammatory response that causes impairment of the vascular, coagulation, and immune systems, leading to multiorgan failure and shock, and thus, in some ways, resembling septic shock. The major affected countries, Sierra Leone, Guinea, Liberia, and Nigeria, have been struggling to contain and to mitigate the outbreak. Gene sequencing of the 2014 virus (2014WA) outbreak has demonstrated 98% homology with the Zaire Ebola virus, with a 49% case fatality ratio across the affected countries. In this review the characteristics of the viruses, pathogenesis, diagnosis, treatment, and the cases reported in health care workers (HCW) are described, as well as a summary of outbreaks of the virus since its discovery, including these last two outbreaks in Africa
