Effectiveness of Land- and Water-based Exercise on Fatigue and Sleep Quality in Women With Fibromyalgia: The al-Ándalus Quasi-Experimental Study.

OBJECTIVE: To assess the effectiveness of 24 weeks of land- and water-based exercise on fatigue and sleep quality in women with fibromyalgia, and the persistence of changes 12 weeks after exercise cessation. DESIGN: Quasi-experimental study. SETTING: University facilities and fibromyalgia associations. PARTICIPANTS: Women with fibromyalgia (N=250; 50.8±7.6 years old). INTERVENTIONS: Participants were assigned to land-based exercise (n=83), water-based exercise (n=85), or no exercise control (n=82) groups. The intervention groups engaged in a similar multicomponent exercise program for 24 weeks. MAIN OUTCOME MEASURES: The Multidimensional Fatigue Inventory and Pittsburgh Sleep Quality Index were used. RESULTS: Intention-to-treat analyses revealed that, compared with the control group, at week 24: (i) the land-based exercise group improved physical fatigue (mean difference -0.9 units; 95% confidence interval -1.7 to -0.1; Cohen's d=0.4) and (ii) the water-based exercise group improved general fatigue (-0.8; -1.4 to -0.1, d=0.4), and global sleep quality (-1.6; -2.7 to -0.6, d=0.6). Additionally, compared with the land-based exercise group, the water-based exercise group improved global sleep quality (-1.2; -2.2 to -0.1, d=0.4). Changes were generally not sustained at week 36. CONCLUSION: Land-based multicomponent exercise improved physical fatigue, whereas water-based exercise improved general fatigue and sleep quality. The magnitude of the changes was small-to-medium, and no benefits were maintained after exercise cessation.

Evaluation of LoRa Technology in Flooding Prevention Scenarios.

Global climate change originates frequent floods that may cause severe damage, justifying the need for real-time remote monitoring and alerting systems. Several works deal with LoRa (Long Range) communications over land and in the presence of obstacles, but little is known about LoRa communication reliability over water, as it may happen in real flooding scenarios. One aspect that is known to influence the communication quality is the height at which nodes are placed. However, its impact in water environments is unknown. This is an important aspect that may influence the location of sensor nodes and the network topology. To fill this gap, we conducted several experiments using a real LoRa deployment to evaluate several features related to data communication. We considered two deployment scenarios corresponding to countryside and estuary environments. The nodes were placed at low heights, communicating, respectively, over the ground and over the water. Measurements for packet loss, received signal strength indicator (RSSI), signal-to-noise ratio (SNR) and round-trip time (RTT) were collected during a period of several weeks. Results for both scenarios are presented and compared in this paper. One important conclusion is that the communication distance and reliability are significantly affected by tides when the communication is done over the water and nodes are placed at low heights. Based on the RTT measurements and on the characteristics of the hardware, we also derive a battery lifetime estimation model that may be helpful for the definition of an adequate maintenance plan.

Identification of Data Injection Attacks in Networked Control Systems Using Noise Impulse Integration.

The benefits of using Networked Control Systems (NCS) in the growing Industry 4.0 arenumerous, including better management and operational capabilities, as well as costs reduction.However, despite these benefits, the use of NCSs can also expose physical plants to new threatsoriginated in the cyber domain-such as data injection attacks in NCS links through which sensorsand controllers transmit signals. In this sense, this work proposes a link monitoring strategy toidentify linear time-invariant (LTI) functions executed during controlled data injection attacksby a Man-in-the-Middle hosted in an NCS link. The countermeasure is based on a bioinspiredmetaheuristic, called Backtracking Search Optimization Algorithm (BSA), and uses white Gaussiannoise to excite the attack function. To increase the accuracy of this countermeasure, it is proposedthe Noise Impulse Integration (NII) technique, which is developed using the radar pulse integrationtechnique as inspiration. The results demonstrate that the proposed countermeasure is able toaccurately identify LTI attack functions, here executed to impair measurements transmitted bythe plant sensor, without interfering with the NCS behavior when the system is in its normaloperation. Moreover, the results indicate that the NII technique can increase the accuracy of the attackidentification.

Generic Sensor Failure Modeling for Cooperative Systems.

The advent of cooperative systems entails a dynamic composition of their components. As this contrasts current, statically composed systems, new approaches for maintaining their safety are required. In that endeavor, we propose an integration step that evaluates the failure model of shared information in relation to an application's fault tolerance and thereby promises maintainability of such system's safety. However, it also poses new requirements on failure models, which are not fulfilled by state-of-the-art approaches. Consequently, this work presents a mathematically defined generic failure model as well as a processing chain for automatically extracting such failure models from empirical data. By examining data of an Sharp GP2D12 distance sensor, we show that the generic failure model not only fulfills the predefined requirements, but also models failure characteristics appropriately when compared to traditional techniques.

A Survey on Data Quality for Dependable Monitoring in Wireless Sensor Networks.

Wireless sensor networks are being increasingly used in several application areas, particularly to collect data and monitor physical processes. Non-functional requirements, like reliability, security or availability, are often important and must be accounted for in the application development. For that purpose, there is a large body of knowledge on dependability techniques for distributed systems, which provide a good basis to understand how to satisfy these non-functional requirements of WSN-based monitoring applications. Given the data-centric nature of monitoring applications, it is of particular importance to ensure that data are reliable or, more generically, that they have the necessary quality. In this survey, we look into the problem of ensuring the desired quality of data for dependable monitoring using WSNs. We take a dependability-oriented perspective, reviewing the possible impairments to dependability and the prominent existing solutions to solve or mitigate these impairments. Despite the variety of components that may form a WSN-based monitoring system, we give particular attention to understanding which faults can affect sensors, how they can affect the quality of the information and how this quality can be improved and quantified.

Fibromyalgia has a larger impact on physical health than on psychological health, yet both are markedly affected: the al-Ándalus project.

OBJECTIVES: To characterize a representative sample of fibromyalgia women based on a set of relevant factors known to be related to this disease. To distinguish specific factors of the disease from other symptoms that might also exist in non-fibromyalgia women. To test whether fibromyalgia affects more severely physical or psychological outcomes. METHODS: A total of 459 fibromyalgia women vs. 214 non-fibromyalgia (control) women from Southern Spain (Andalusia) took part in this cross-sectional study. Several instruments were used to assess tenderness, impact of fibromyalgia, fatigue, health-related quality of life, mental health, and cognitive performance. RESULTS: Overall, fibromyalgia women showed a worse status in pain, fatigue, health-related quality of life, depression, and anxiety than controls (P < 0.01). In general, the observed associations presented very large effect sizes (Cohen׳s d from ~1 to ~5.5). No differences between fibromyalgia and controls were observed in cognitive and memory performance, except for delayed recall, but the observed effect size was low (~0.25). The effect size observed for the global physical component (~3.3) was larger than that for the global psychological component (~1.3), all P < 0.001. CONCLUSIONS: Our results reinforce the understanding of fibromyalgia as a polysymptomatic distress condition with pain as its main symptom. Our findings support that fibromyalgia seems to have a greater impact on physical than on psychological outcomes, though both are largely affected.

Motivos de los ciudadanos para realizar ejercicio físico: un estudio desde la teoría de la autodeterminación / Reasons why people do exercise: A study using Self-Determination Theory

Basado en la teoría de la autodeterminación, el objetivo de este estudio fue analizar las relaciones entre los motivos para el ejercicio físico y la frecuencia informada de práctica semanal en una muestra representativa de la población adulta de una ciudad. En este estudio participaron 918 habitantes, con edades comprendidas entre los 16 y 89 años. Los participantes contestaron el autoinforme de motivos para la práctica de ejercicio físico e informaron sobre la asiduidad con la que realizaban ejercicio físico. Controlando los efectos de la edad y el sexo, los análisis multivariantes de covarianza mostraron que los participantes que realizaban ejercicio físico con mayor frecuencia semanal informaron puntuaciones más altas en los motivos autodeterminados y no autodeterminados para practicar ejercicio físico, a excepción del motivo de urgencias de salud. Los resultados apoyan los supuestos de la teoría de la autodeterminación al sugerir que los participantes van internalizando la conducta del ejercicio a medida que son más activos físicamente. Sin embargo, los resultados también indican que determinados motivos no autodeterminados se muestran pertinentes para la práctica física. Los responsables de la política deportiva municipal deberían buscar formas apropiadas de combinar motivos no autodeterminados con formas más internalizadas que garanticen una adherencia más prolongada al ejercicio.

Based on self-determination theory, the objective of this study was to analyze the relationship between the reasons for exercise and its reported weekly frequency in a representative sample of an adult urban population. A total of 918 inhabitants, aged between 16 and 89, participated in this study answering the Spanish version of the Exercise Motivations Inventory-2 (EMI-2) and reporting on their exercise frequency. Controlling for the influence of age and gender, multivariate analysis of covariance (MANCOVA) showed that participants who reported the highest exercise frequency had the highest score on both self-determined and controlling exercise motives, except the ill-health avoidance motive. The results support propositions of self-determination theory, and suggest that citizens may internalize exercise behaviour as they become more physically active. However, the results also suggest that some controlling motives are pertinent to exercise. Decision makers of the local sport policy should look into suitable ways of combining both controlling motives and more internalized motives in order to produce long lasting exercise adherence in citizens.

Effect of stretching program in an industrial workplace on hamstring flexibility and sagittal spinal posture of adult women workers: a randomized controlled trial.

OBJECTIVES: To determine the effect of a stretching program performed in the workplace on the hamstring muscle extensibility and sagittal spinal posture of adult women. MATERIAL AND METHODS: Fifty-eight adult women volunteers (mean age of 44.23 ± 8.87 years) from a private fruit and vegetable company were randomly assigned to experimental (n=27) or control (n=31) groups. The experimental group performed three exercises of hamstrings stretching of 20 seconds per exercise, three sessions a week for a period of 12 weeks. The control group did not participate in any hamstring stretching program. Hamstring flexibility was evaluated through the passive straight leg raise test and toe-touch test, performed both before and after the stretching program. Thoracic and lumbar curvatures and pelvic inclination were measured in relaxed standing and toe-touch test with a Spinal Mouse. RESULTS: Significant increases (p < 0.01) in toe-touch score and straight leg raise angle (in both legs) were found in the experimental group during post-test, while the control group showed a non-significant decrease for both toe-touch score and straight leg raise test. A significant decrease in thoracic curve and significant increase in pelvic inclination were found in the toe-touch test for the experimental group (p <0.05). However, no significant changes were found in standing posture for any group. CONCLUSIONS: Hamstring stretching exercises performed in the working place are effective for increasing hamstring muscle extensibility. This increase generates a more aligned thoracic curve and more anterior pelvic inclination when maximal trunk flexion is performed.

Análisis de la morfología del raquis torácico y lumbar en mujeres trabajadoras de una cooperativa hortofrutícola / men Analysis of the thoracic and lumbar morphology in woworkers from a fruit and vegetable company

El objetivo del presente estudio fue analizar la disposición angular del raquis torácico y lumbar en bipedestación y sedentación relajada en mujeres trabajadoras de una empresa hortofrutícola. Un total de 50 mujeres (media de edad: 43,62+/-8,43 años) fueron evaluadas mediante un spinal mouse en bipedestación y en sedentación relajada. Los valores angulares medios para el raquis torácico y lumbar fueron de 32,74+/-8,76 y -21,66+/-19,12 en bipedestación y de 36,32+/-10,55 y -1,08+/-18,14, en sedentación. En bipedestación, un elevado porcentaje de casos (86 por ciento y 68,3 por ciento) presentaban una cifosis torácica y lordosis lumbar dentro de los valores de normalidad. En sedentación, el 74 por ciento presentaban hipercifosis torácica y el 20 por ciento una inversión lumbar. En conclusión, aunque en bipedestación la mayoría de las mujeres presentaban una morfología del raquis dentro de los valores de normalidad, en sedentación se observó un elevado porcentaje de casos con hipercifosis torácica y el raquis lumbar en inversión. Debido a las consecuencias negativas que se asocian a dichas desalineaciones raquídeas, es recomendable aplicar programas de mejora de la actitud postural en estas trabajadoras, preferentemente en su contexto laboral.

The aim of this study was to analyze the sagittal spinal morphology of thoracic and lumbar spine in standing and sitting in women workers from a cooperative in the production, handling and marketing business of vegetable and fruit products. A total of 50 women (mean age: 43.62+/-8.43 years old) were evaluated. The spinal mouse system was used to mesasure the sagittal thoracic and lumbar curvatures in standing and relaxed sitting. The values for thoracic and lumbar curvatures were 32.74+/-8.76 and -21.66+/-19.12 in standing and 36.32+/-10.55 and -1.08+/-18.14 in sitting. A high frequency (86.0 percent and 68.3 percent) of normal thoracic kyphosis and lumbar lordosis were found in standing posture. While sitting the 74.0 percent and 20.0 percent presented thoracic hyperkyphosis and lumbar kyphosis. In conclusion, a high percentaje of women workers presented normality values in standing posture, although a high percentage of women were found with thoracic hyperkyphosis and lumbar flexed while sitting relaxed. It is recommended that these women carry out a program to improve their actitudinal postures in their work place.

Evolución de la morfología del raquis e inclinación pélvica en ciclistas de diferentes edades: un estudio transversal / Evolution of spinal morphology and pelvic tilt in cyclists of different ages. A cross sectional study

El objetivo principal del estudio fue determinar la morfología del raquis e inclinación pélvica en bipedestación en tres grupos de ciclistas de distintas edades, con un volumen de entrenamiento y experiencia similares. Un total de 65 ciclistas fueron divididos en tres grupos de edad: grupo 1 ( 30 años; n = 20); grupo 2 (entre 31 y 40 años; n = 25); y grupo 3 ( 41 años; n = 20). Posteriormente se les evaluó la morfología sagital del raquis torácico, lumbar e inclinación pélvica en bipedestación, mediante el sistema Spinal Mouse. Los valores angulares medios para el raquis torácico, lumbar e inclinación pélvica para el grupo 1 fueron: 46,60 +/- 10,09; - 26,40 +/- 7,17; 13,20 +/- 4,94; para el grupo 2: 47,64 +/- 8,58; -26,92 +/- 6,34; 12,24 +/- 4,45; y para el grupo 3: 50,75 +/- 12,77; -20,70 +/- 10,10 y 8,15 +/- 8,21. Se encontraron diferencias significativas en el raquis lumbar e inclinación pélvica en los grupos 1 y 2, con respecto al 3. En conclusión, la edad es un factor que condiciona la morfología del raquis e inclinación pélvica en ciclistas que presentan los mismos años de práctica y volumen de entrenamiento en ciclismo.

The aim of this study was to evaluate the sagittal spinal morphology and pelvic tilt in standing in three different age-group cyclists who had the same cycling experience and training volume. A total of 65 cyclists were divided in three age-groups: group 1: ( 30 years old; n = 20); group 2 (between 31 y 40 years old; n = 25); and group 3 ( 41 years old; n = 20). The Spinal Mouse was used to measure sagittal thoracic and lumbar spine and pelvic tilt in standing on the floor. The mean values for thoracic and lumbar spine and pelvic tilt were: group 1, 46.60 +/- 10.09; - 26.40 +/- 7.17; 13.20 +/- 4.94; group 2, 47.64 +/- 8.58; -26.92 +/- 6.34; 12.24 +/- 4.45; and group 3, 50.75 +/- 12.77; -20.70 +/- 10.10 y 8.15 +/- 8.21, respectively. Significant differences were found for the lumbar spine and pelvic tilt in the groups 1 and 2 with respect to group 3. In conclusion, aging is a conditional factor to the sagittal spinal morphology and pelvic tilt in cyclists who present the same years of experience and training volume in cycling.

Land- and water-based exercise intervention in women with fibromyalgia: the al-Andalus physical activity randomised controlled trial.

BACKGROUND: The al-Andalus physical activity intervention study is a randomised control trial to investigate the effectiveness of a land- and water-based exercise intervention for reducing the overall impact of fibromyalgia (primary outcome), and for improving tenderness and pain-related measures, body composition, functional capacity, physical activity and sedentary behaviour, fatigue, sleep quality, health-related quality of life, and cognitive function (secondary outcomes) in women with fibromyalgia. METHODS/DESIGN: One hundred eighty women with fibromyalgia (age range: 35-65 years) will be recruited from local associations of fibromyalgia patients in Andalucía (Southern Spain). Patients will be randomly assigned to a usual care (control) group (n = 60), a water-based exercise intervention group (n = 60) or a land-based exercise intervention group (n = 60). Participants in the usual care group will receive general physical activity guidelines and participants allocated in the intervention groups will attend three non-consecutive training sessions (60 min each) per week during 24 weeks. Both exercise interventions will consist of aerobic, muscular strength and flexibility exercises. We will also study the effect of a detraining period (i.e., 12 weeks with no exercise intervention) on the studied variables. DISCUSSION: Our study attempts to reduce the impact of fibromyalgia and improve patients' health status by implementing two types of exercise interventions. Results from this study will help to assess the efficacy of exercise interventions for the treatment of fibromyalgia. If the interventions would be effective, this study will provide low-cost and feasible alternatives for health professionals in the management of fibromyalgia. Results from the al-Andalus physical activity intervention will help to better understand the potential of regular physical activity for improving the well-being of women with fibromyalgia.

Incidencia de un programa de actividad física en la calidad de vida de los trabajadores en su ámbito laboral / Impact of a program of physical activity on quality of life of workers in their workplace

Para el funcionamiento adecuado de cualquier organización juega un papel muy importante la calidad de vida en el trabajo. El conocimiento de las principales causas de absentismo laboral en el sector agroalimentario (problemas de espalda y enfermedades mentales relacionadas con el estrés laboral)nos han conducido a desarrollar un programa de intervención multidisciplinar que incide positivamente en estas patologías o dolencias, tanto en la prevención como en el tratamiento y recuperación de las mismas. Este proyecto de salud integral ha pretendido mejorar la calidad de vida de las trabajadoras y la productividad de la empresa, tanto a nivel individual como colectivo, compensando la carga física que supone el tipo de tareas desarrolladas por las trabajadoras (posición prolongada de pie), a través de un programa de tonificación y extensibilidad de la musculatura de sostén de la columna vertebral en estas mujeres, además de ejercicios de relajación y respiración. En este artículo se presentan los resultados obtenidos a través del cuestionario de calidad de vida SF-36 (Short Form 36Health Survery). Después de 3,5 meses (marzo-junio 2010)del programa de intervención, con 2 sesiones semanales de 30minutos de actividad física saludable al comenzar o finalizar su jornada laboral, se han producido, además de una disminución en el dolor de espalda, mejoras estadísticamente significativas en la dimensiones/conceptos: función física, rol físico, dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental de las trabajadoras. A raíz de los resultados obtenidos se justifica que este tipo de proyectos sean incorporados a otras organizaciones e instituciones (AU)

For the proper functioning of any organiztion plays a very important quality of life at work. Knowledge of the main causes of absenteeism in the food industry (back problems and mental illness related to work stress) have led us to develop a multidisciplinary intervention program positively affects these diseases or conditions, both in prevention and in the treatment and recovery from them. This comprehensive health project has sought to improve the quality of life of workers and productivity of the company, both individually and collectively, offsetting the physical strain imposed on the type of tasks performed by workers (long standing position) through a toning program and extensibility of the muscles supporting the spine in these women, as well as relaxation and breathing exercises. This article presents the results obtained through the quality of life questionnaire SF-36 (Short Form 36 Health Survery). After 3.5 months (March-June 2010) the intervention program, with two weekly sessions of 30 minutes of physical activity healthy to begin or end their workday, they were produced, and a decrease in back pain statistically significant improvements in the dimensions / concepts: physical function, role physical, bodily pain, general health, vitality, social function, emotional role and mental health workers. Following the results obtained justify such projects are incorporated into other organizations and institutions (AU)

Incidência de fungos em polpas de cajá produzidas no município de Fortaleza: uma análise comparativa entre os métodos convencional e simplate / Incidence of fungos in produced pulps of cajá in the city of Fortaleza: a comparative analysis between the methods conventional and simplate

As polpas de frutas são, freqüentemente, atacadas por fungos, que causam alterações na sua composição química. O método Convencional utilizado na determinação desses microrganismos necessita de 1 a 5 dias para liberação dos resultados. O Método Simplate permite a enumeração de bolores e leveduras em 48 horas, através de tecnologia que correlaciona atividade enzimática com a presença de fungos no alimento. A presença de leveduras é identificada pelo aparecimento de coloração azul fluorescente no meio de crescimento, quanto exposto à luz ultravioleta. Os bolores devem ser qualificados visualmente através do crescimento superficial. As polpas de cajá congeladas (40 amostras), adquiridas de 4 empresas produtoras localizadas em Fortaleza, foram submetidas à determinação de fungos através dos métodos Simplate e Convencional. Determinou-se o índice de adequação à legislação vigente através dos dois métodos. Procedeu-se à análise estatística dos resultados através da aplicação dos teste de Tukey, t-pareado e análise de variância (ANOVA). Os resultados revelaram que, a nível de 5 por cento de significância, não existe diferença entre os métodos.
