Health-protective behaviours and risk of fall-related hip fractures: a population-based case-control study

Background: fall-related hip fractures are one of the most common causes of disability and mortality in older age. The study aimed to quantify the relationship between lifestyle behaviours and the risk of fall-related hip fracture in community-dwelling older people. The purpose was to contribute evidence for the promotion of healthy ageing as a population-based intervention for falls injury prevention. Methods: a case-control study was conducted with 387 participants, with a case-control ratio of 1:2. Incident cases of fall-related hip fracture in people aged 65 and over were recruited from six hospital sites in Brisbane, Australia, in 2003-04. Community-based controls, matched by age, sex and postcode, were recruited via electoral roll sampling. A questionnaire designed to assess lifestyle risk factors, identified as determinants of healthy ageing, was administered at face-to-face interviews. Results: behavioural factors which had a significant independent protective effect on the risk of hip fracture included never smoking [adjusted odds ratio (AOR): 0.33 (0.12-0.88)], moderate alcohol consumption in mid- and older age [AOR: 0.49 (0.25-0.95)], not losing weight between mid- and older age [AOR: 0.36 (0.20-0.65)], playing sport in older age [AOR: 0.49 (0.29-0.83)] and practising a greater number of preventive medical care [AOR: 0.54 (0.32-0.94)] and self-health behaviours [AOR: 0.56 (0.33-0.94)]. Conclusion: with universal exposures, clear associations and modifiable behavioural factors, this study has contributed evidence to reduce the major public health burden of fall-related hip fractures using readily implemented population-based healthy ageing strategies.

An examination of the role of the sports and exercise medicine specialist in Ireland- from epidemiology to treatment

The expansion of the specialty of sports and exercise medicine (SEM) is a relatively recent development in the medical community and the role of the SEM specialist continues to evolve and develop. The SEM specialist is ideally placed to care for all aspects of physical activity not only in athletes but also in the general population. As an advocate for physical activity the SEM specialist plays a broad role in advising safe effective sports and recreation participation; screening for disease related to sports participation; examining and contributing to the evidence behind treatment strategies and evaluating any potential negative impact of sports injury prevention measures. In this thesis I will demonstrate the breadth of the role the Sports and Exercise Medicine Specialist from epidemiology to in-depth examination of treatment strategies. In Chapter 2, I examined the epidemiology of sports and recreation related injury (SRI) in Ireland, an area that has previously been poorly studied. We report on 3,172 SRI (14% of total presentations) presentations to the ED over 6 months. Paediatric patients (4-16 yrs) were over represented comprising 39.9% of all SRI presentation compared to 16% of total ED presentations and 18% of the general population. These injuries were serious (32% fractures) and though 49% of injuries occurred during organised competition/practice, 41.5% occurred during recreation-most often at home. In Chapter 3, I examined risk factors associated with hand injury in hurling. The previous chapter highlighted the importance of a firm evidence base underpinning treatment strategies. When measures to improve welfare are introduced not only must potential benefits be measured, so too must potential unwanted adverse outcomes. In this study I examined a cohort of adult hurlers who had presented to the ED with a hurling related injury in order to highlight the variables associated with hand injury in this population. I found the athletes who wore a helmet were far more likely (OR 3.15 95% CI (1.51-6.56) p= 0.002) to suffer a hand injury than athletes who did not. Very few of those interviewed (4.9%) used hand protection compared to 65% who used helmet and faceguard. The introduction of the helmet and faceguard in hurling has undeniably decreased the incidence of head and face injury in hurling. However in tandem with this intervention several observational studies have demonstrated an increase in the occurrence of hurling related hand injuries. This study highlights the importance of being cognisant of unanticipated or unintended consequences when implementing a new treatment or intervention. In Chapter 4, I examined the role of population screening as applied to sport and exercise. This is a controversial area –cardiac screening in the exercising population has been the subject of much debate. Specifically I define the prevalence of exercise induced bronchoconstriction (EIB) using a specifically designed sports specific field-testing protocol. In this study I found almost a third (29%) of a full international professional rugby squad had confirmed asthma or EIB, as compared with 12-15% of the general population. Despite regular medical screening, 5 ‘new’ untreated cases (12%) were elicited by the challenge test and in the group already on treatment for asthma/EIB; over 50% still displayed EIB. In Chapter 5, I examined the evidence supporting current treatment options for iliotibial band friction syndrome (ITBFS). The practice of sports medicine has traditionally been ‘eminence based’ rather than ‘evidence based’. This may be problematic as some of these practices are based upon flawed principles- for example the treatment of iliotibial band friction syndrome (ITBFS). In this chapter, using cadaveric and biomechanical studies I expand upon the growing base of evidence clarifying the anatomy and biomechanics of the area-thereby re-examining the principles on which current treatments are based. The role of the SEM specialist is broad; we chose to examine specific examples of some of the roles that they execute. An understanding of the epidemiology of SRI presenting to the ED has implications for individual patients, sports governing bodies and health resource utilisation. Population screening is an important tool in health promotion and disease prevention in the general population. Screening in SEM may have similar less well-recognised benefits. The SEM specialist needs to be conversant in screening for medical conditions concerning physical activity. A comprehensive understanding of the pathophysiology of a disease is required for its diagnosis and treatment. Due to the ongoing evolution of SEM many treatments are eminence-based rather than evidence‐based practice. Continued re-examination of the fundamentals of current practice is essential. An awareness of potential unwanted side effects is essential prior to the introduction of any new treatment or intervention. The SEM specialist is ideally placed to advise sports governing bodies on these issues prior to and during their implementation.

Iowa Immunization Program Annual Report 2013, April 30, 2014

The Bureau of Immunization is part of the Division of Acute Disease Prevention and Emergency Response (ADPER) at the Iowa Department of Public Health (IDPH). The ADPER division provides support, technical assistance and consultation to local hospitals, public health agencies, community health centers, emergency medical service programs and local health care providers regarding infectious diseases, disease prevention and control, injury prevention and public health and health care emergency preparedness and response. The division encompasses the Center for Acute Disease Epidemiology (CADE), the Bureau of Immunization and Tuberculosis (ITB), the Bureau of Emergency Medical Services (EMS), the Bureau of Communication and Planning (CAP), the Office of Health Information Technology (HIT), and the Center for Disaster Operations and Response (CDOR). The Bureau of Immunization and Tuberculosis includes the Immunization Program, the Tuberculosis Control Program, and the Refugee Health Program. The mission of the Immunization Program is to decrease vaccine‐preventable diseases through education, advocacy and partnership. While there has been major advancement in expanding immunizations to many parts of Iowa’s population, work must continue with public and private health care providers to promote the program’s vision of healthy Iowans living in communities free of vaccine‐preventable diseases. Accomplishing this goal will require achieving and maintaining high vaccination coverage levels, improving vaccination strategies among under‐vaccinated populations, prompt reporting and thorough investigation of suspected disease cases, and rapid institution of control measures. The Immunization Program is comprised of multiple programs that provide immunization services throughout the state: Adolescent Immunization Program, Adult Immunization Program, Immunization Registry Information System (IRIS), Vaccines for Children Program (VFC), Perinatal Hepatitis B Program, and Immunization Assessment Program.

Skadeförebyggande träningsmetoder mot hamstringsskador inom svensk herrelitfotboll i jämförelse med rekommenderad evidensbaserad forskning

Purpose The purpose of this study was to describe the evidence-based research recommendations on injury prevention methods against hamstring injuries among Swedish men's elite team in football. The research-based recommendations was then to be compared with the way Swedish elite football teams work to prevent hamstrings injuries. Method First a literature search of PubMed and SPORTDiscuss was made to find the most evidence-based training methods to hamstring injuries. Then an Internet questionnaire regarding injury prevention training methods against hamstring injuries was sent to all Swedish elite football teams. The answers off the questionnaire was then compared with the research that had the most evidence based training methods to hamstring injuries. Results Research shows that the method with the most evidence is eccentric strength training. Flexibility, static stretch and core stability training is research methods that can be used to prevent hamstrings injuries but these methods lack a large validated research basis. 8 of 32 (25 %) teams answered the questionnaire. All teams indicated that they were working with injury prevention methods but the methods varied from the eccentric strength training to periodization and flexibility training. 2 of 8 teams indicated that they worked with eccentric strength training that is recommended by science as the most evidence-based training method. Conclusion The study shows that the teams partly work after what the research recommends as the most evidence-based training methods against hamstring injuries. However, the study lacks validity and further research is needed before definitive conclusions can be drawn.

O treino como meio de desenvolvimento global do atleta : relatório de estágio em futebol realizado na equipa de juniores do Grupo Desportivo Alcochetense, 1ª Divisão Distrital da AF Setúbal, época 2014- 2015

No dia a dia de uma equipa, muitos são os fatores que influenciam o seu funcionamento e a sua construção. Uma constante adaptação ao contexto envolvente e à evolução em termos de conhecimento científico, são fatores determinantes no trabalho de um treinador. Desta forma, possuindo mais e melhores ferramentas de trabalho, permitir-lhe-á maximizar a aprendizagem e o rendimento dos seus jogadores. Neste relatório, pretende-se apresentar, analisar e refletir sobre a conceção e implementação das atividades práticas durante toda a época desportiva da equipa de Juniores do Grupo Desportivo Alcochetense, Para além da parte ligada às várias áreas do treino, este relatório irá abranger outras áreas de grande importância na vida de um treinador, sendo elas a área de Inovação e Investigação (Área 2) e a Relação com a Comunidade (Área 3). Com base na análise do contexto e nos objetivos definidos para a equipa, descrevemos e fundamentamos o modelo de jogo criado pela equipa técnica, assim como o planeamento definido para a época desportiva. Através de uma categorização dos exercícios de treino, foi possível fazer uma quantificação do volume de treino de cada categoria, o que permitiu perceber quais os conteúdos mais abordados durante toda a época desportiva. Na área 2 do estágio, procuramos aprofundar o conhecimento em torno da inclusão do trabalho físico complementar como meio de prevenção de lesões no processo de treino de uma equipa de futebol e a relação que este pode ter no desempenho desportivo. Embora não tenha sido possível proceder à sua aplicação prática, parece clara a importância deste tipo de abordagem no treino de uma equipa de futebol. Como tal, apresentamos uma proposta de protocolo de treino de prevenção de lesões. No âmbito da área 3, partindo da necessidade da comunidade de treinadores de futebol em manter uma formação teórica continua, foram organizadas duas ações de formação, em parceria com o Núcleo de Lisboa da Associação Nacional de Treinadores de Futebol, sobre a temática da Organização Estrutural do Exercício em Futebol e sobre as Bases para a construção de uma equipa de Futebol.

Caregiver factors and pool fencing: An exploratory analysis

To explore the relationship between caregiver characteristics and the adequacy of domestic swimming pool fencing.A typical metropolitan area of a large Australian capital city, Brisbane.From a reanalysis of the dataset of the 1989 Brisbane Home Safety Survey of 1050 householders, associations between 10 caregiver factors, pool ownership, and quality of pool fencing, were analysed. Household characteristics relating to toddlers (children < or = 4 years), and socioeconomic measures were also included in the analyses. Pool fencing quality was measured on an ordinal scale derived from Australian Standards Association guidelines, confirmed through home visits by trained inspectors.Caregiver factors did not distinguish households with a swimming pool from those without, nor were they associated with adequacy of pool fencing among pool owners. Pool owners, with or without children, were less likely to perceive having a childproof fence as being important. Strongest correlates of adequacy of pool fencing were socioeconomic indicators of surrounding districts.These results do not support the arguments of opponents of compulsory pool fencing that caregiver factors are adequate to prevent toddler drownings and obviate the need for a pool fence. Pool owners do not appear to perceive their pool as a hazard for young children, and complacency about the adequacy of pool fencing needs to be replaced by increased caregiver health beliefs, skills, and perceptions.

El ejercicio y el desempeño musical: doce semanas de actividad física mejoran la capacidad de ejecución de un instrumento musical en estudiantes de conservatorio

Con el fin de evaluar los cambios que produce un programa de actividad física en la percepción que tienen los músicos sobre su capacidad de ejecución de un instrumento musical, se realizó una intervención con un programa de actividad física basado en la técnica Pilates, durante 12 semanas, en el Conservatorio de Música de la Universidad Nacional de Colombia, con estudiantes del programa de música instrumental. Se midieron parámetros de la aptitud física (capacidad cardiorrespiratoria, fuerza, flexibilidad y composición corporal) y de la percepción de la capacidad de ejecución (fatiga muscular, nivel de esfuerzo, dolor y fluidez) antes y después de la intervención. Los resultados arrojaron cambios positivos en la aptitud física logrando un aumento significativo en la flexibilidad y resistencia de los miembros inferiores en 14 participantes (70% de la muestra), y en la percepción de la capacidad de ejecución instrumental con el retraso en la aparición de la fatiga muscular mientras se está ejecutando el instrumento (30 minutos en promedio). Esto permite a los músicos abordar un repertorio extenso con menor fatiga, minimizando el riesgo de lesión o alteraciones musculo-esqueléticas que influyan directamente en su desempeño técnico y artístico.

Niveles de actividad física y su relación con los desórdenes musculo esqueléticos en profesores de educación física en Bogotá - Colombia.

La actividad física regular desempeña un papel fundamental en la prevención y control de los desórdenes musculo esqueléticos, dentro de la actividad laboral del profesor de educación física. Objetivo: El propósito del estudio fue determinar la relación entre los niveles de actividad física y la prevalencia de los desórdenes musculo esqueléticos, en profesores de educación física de 42 instituciones educativas oficiales de Bogotá-Colombia. Métodos. Se trata de un estudio de corte transversal en 262 profesores de educación física, de 42 instituciones educativas oficiales de Bogotá - Colombia. Se aplicó de manera auto-diligenciada el Cuestionario Nórdico de desórdenes músculos esqueléticos y el Cuestionario IPAQ versión corta para identificar los niveles de actividad física. Se obtuvieron medidas de tendencia central y de dispersión para variables cuantitativas y frecuencias relativas para variables cualitativas. Se calculó la prevalencia de vida y el porcentaje de reubicación laboral en los docentes que habían padecido diferentes tipo de dolor. Para estimar la relación entre el dolor y las variables sociodemográficas de los docentes, se utilizó un modelo de regresión logística binaria simple. Los análisis fueron realizados en SPSS versión 20 y se consideró como significativo un valor p < 0.05 para el contraste de hipótesis y un nivel de confianza para la estimación de parámetros. Resultados: El porcentaje de respuesta fue del 83.9%, se consideraron válidos 262 registros, 22.5% eran de género femenino, la mayor cantidad de docentes de educación física se encuentraon entre 25 y 35 años (43,9%), frente a los desórdenes musculo esqueléticos, el 16.9% de los profesores reporto haberlos sufrido alguna vez molestias en el cuello, el 17,2% en el hombro, 27,9% espalda, 7.93% brazo y en mano el 8.4%. Los profesores con mayores niveles de actividad física, reportaron una prevalencia menor de alteraciones musculo esqueléticas de 16,9 % para cuello; 27.7% para dorsal/lumbar frente a los sujetos con niveles bajos de actividad física. La presencia de los desórdenes se asoció a los años de experiencia (OR 3.39 IC95% 1.41-7.65), a pertenecer al género femenino (OR 4.94 IC95% 1.94-12.59), a la edad (OR 5.06 IC95% 1.25-20.59), y al atender más de 400 estudiantes a cargo dentro de la jornada laboral (OR 4.50 IC95% 1.74-11.62). Conclusiones: En los profesores de Educación Física no sé encontró una relación estadísticamente significativa entre los niveles de actividad física y los desórdenes musculo esqueléticos medidos por auto reporte.

Desórdenes muscoloesqueléticos en el trabajador avícola – intervenciones en salud

Introducción: El trabajador avícola presenta un alto riesgo de sufrir de Desórdenes Musculo esqueléticos, debido a la realización de trabajos manuales repetitivos; posición bípeda prolongada, posturas por fuera de ángulos de confort de miembros superiores Objetivo: Establecer las recomendaciones basadas en la evidencia de las intervenciones en salud para los Desórdenes Musculoesqueléticos (DME) en el trabajador avícola. Metodología: Se realizó una revisión de la literatura de los estudios primarios publicados en las bases de datos Medline, Scient Direct y Scielo desde 1990. Los artículos se clasificaron de acuerdo con: el tipo de estudio, la calidad de éste y el nivel de evidencia que aportaba. Resultados: Dentro de las recomendaciones de la evidencia disponible para el manejo integral de los pacientes de la industria avícola con riesgos o eventos asociados a DME se encuentran las siguientes: 1) incorporar un enfoque sistémico en la atención a dichos trabajadores, 2) incluir aspectos psicosociales en la identificación y explicación de los riesgos y eventos en salud, 3) permitir los descansos, microrupturas y pautas para el ejercicio, 4) facilitar la rotación y ampliación de puestos de trabajo, 5) mejorar las herramientas de trabajo - especialmente el corte de los cuchillos. Conclusiones: Las intervenciones descritas en la presente revisión, apuntan hacia el mejoramiento de la incidencia y la prevalencia de los DMS, la disminución de incapacidad temporal y definitiva por los DMS, el mejoramiento en la producción industrial y la reducción de costos tanto económicos como humanos. Sin embargo, se debe plantear la necesidad de continuar impulsando el desarrollo de investigaciones y estudios que permitan tener mayores elementos de juicio para poder realizar recomendaciones a los tipos de intervenciones propuestas. A pesar de lo anterior, las intervenciones en salud para los trabajadores de la industria avícola deben ser enfocadas desde la prestación integral de los servicios de salud.

Relación entre los riesgos percibidos por los trabajadores en minería subterránea y los accidentes de trabajo y enfermedades laborales

Introducción: La minería es considerada uno de los sectores económicos más importantes por su capacidad para generar recursos en su propio sector y en otros sectores como metalmecánica, agricultura e informática entre otros, y por su contribución al desarrollo socioeconómico sostenible de las poblaciones. Objetivo: Determinar la relación entre los riesgos percibidos por los trabajadores que laboran en minería subterránea en 3 departamentos de Colombia y los Accidentes de Trabajo (AT) y Enfermedades Laborales (EL). Materiales y Métodos: Estudio de corte transversal en 476 trabajadores de minería subterránea. Se incluyeron variables independientes (características sociodemográficas y laborales y percepción del riesgo) y variables dependientes (enfermedad laboral y accidente de trabajo), obtenidas a través de una entrevista directa aplicada por profesionales de la salud previamente capacitados. Para el análisis estadístico se utilizó la Prueba Exacta de Fisher, el Odds Ratio (OR) con el Intervalo de Confianza (IC) del 95%. Resultados: En los trabajadores de minería subterránea en los departamentos de Boyacá, Cundinamarca y Santander, se encontró relación estadística significativa entre la accidentalidad con la percepción de riesgo por iluminación (OR= 2.059, IC= 95%: 1.116, 3.798, p=0.013), percepción de riesgo por movimientos repetitivos (OR= 1.951, IC= 95%: 0.998, 3.815, p=0.034), percepción de riesgo por ruido (OR= 2.275, IC= 95%: 0.974, 5.312, p=0.039) y percepción de riesgo por manejo de cargas (OR= 1.778, IC= 95%: 0.969, 3.264, p=0.041). Conclusión: se encontró que existe una relación significativa entre la percepción de riesgo de los trabajadores de minería subterránea con accidentes de trabajo y que no existe relación entre esta percepción y las enfermedades laborales.

Unintentional injuries among 16 to 20 year old students in Switzerland.

In our society, accidents constitute a major public health problem, especially among youth. The objective of this paper was to describe the incidence of nonfatal injuries that required medical care among 16 to 20 year-old in Switzerland, its distribution by type of injury and whether there were differences by gender or by academic track and whether these injuries had sequels (hospitalisation, physical and psychological sequels). Overall, 28.3% of the sample reported at least one accident needing medical care in the previous 12 months, with males having more accidents than females and apprentices more than students. By type of accident, sports were the most frequently reported, followed by traffic, leisure time and work accidents. Half of males and one-third of females reported more than one accident, and 16% and 8% of them, respectively, reported four or more. Both physical and psychological sequels were more frequent among females, while hospitalisation was more frequent among males. Accident prevalence rates remain high among adolescents. Safety counselling and environmental measures need to be implemented.

PREVENTION OF CHILLING INJURY IN 'TOMMY ATKINS' MANGOES PREVIOUSLY STORED AT 5 ºC, USING HEAT TREATMENT AND RADIATION UV (UV-C)

ABSTRACT The objective of this study was to evaluate the effect of heat treatment and ultraviolet radiation (UV-C) in the prevention of chilling injury in mangoes cv. Tommy Atkins previously stored or not under injury condition after their transference to ambient condition. Fruits were divided into groups: two were hydrothermally treated (46.1 ºC/90 min; 55 ºC/5 min) and two were exposed to UV-C radiation (1.14 kJ m-2; 2.28 kJ m-2). These groups were stored under chilling injury conditions (5 ºC for 14 days), as established in preliminary tests. Other untreated groups were stored at 12 ºC or 5 ºC. After the storage period, they were transferred to ambient conditions (21.9 ºC; 55% RH) and the quality was evaluated. All the data were submitted to multivariate analysis as the tool to verify the simultaneous effect of the treatments under the quality parameters. The multivariate analysis indicated that the hydrothermal treatments at 46.1 °C/90 min and 55 °C/5 min and the UV-C radiation at doses of 1.14 kJ m-2 and 2.28 kJ m-2 were effective in minimized the symptoms of chilling injury in mangoes ‘Tommy Atkins’ stored at 5 °C for 14 days. However, after their transference to environmental condition at 21.9 °C, only the UV-C kept this control, especially at a dose of 2.28 kJ m-2. This treatment did not prevent the development of the characteristic color or affected the normal ripening and allowed the conservation of fruit for a period of 14 days at 5 °C, plus seven days of storage at environmental condition, which corresponds to the shipping transportation plus the time for sale.

Chilling Injury in Avocados and Its Prevention with Thermal Treatment

The combinations of temperature and time which can cause chilling injuries in avocados 'Geada', 'Quintal' and 'Fortuna' were determined. The binomial 4 degrees C/ 28 days was selected to determine the activity of peroxidase (POD), polyphenoloxidase (PPO), polygalacturonase (PG) and methylesterase pectin (PME). The respiratory activity was also evaluated. The fruits were stored at this condition until being transferred to ambient conditions (22 degrees C and 77% RH) until maturity, when they were compared to fruits stored permanently at this environment, after being cleaned (control). In the second part of this work, different hydrothermal treatments were tested to prevent or minimize chilling injuries. Avocados 'Geada', 'Quintal' and 'Fortuna' were treated at 38 degrees C for 0, 30, 60 and 90 minutes before storage at 4 degrees C for 28 days. It was observed that the activity of enzymes associated to browning, POD and PPO, and to maturation, PG and PME, had become greater in fruits stored at 4 degrees C, or when they were transferred to environmental conditions. Fruits subjected to refrigeration, after transferred to environment, presented lower respiratory peak intensity and it occurred earlier than the others. Treatments using 38 degrees C for 60 and 90 min minimized the symptoms of chilling injury in avocados 'Geada' while for 'Quintal' the most efficient was 38 degrees C for 60 min. In 'Fortuna' these treatments did not minimize the damage by cold.

Prevention of renal ischemia/reperfusion injury in rats using acetylcysteine after anesthesia with isoflurane

OBJETIVO: Avaliar o efeito da N-acetilcisteína na proteção renal contra lesão de isquemia/reperfusão, quando administrada logo após a indução anestésica, em ratos anestesiados com isoflurano. MÉTODOS: Dezoito ratos Wistar machos pesando mais que 300g foram anestesiados com isoflurano. A jugular interna direita e a carótida esquerda foram dissecadas e canuladas. Os animais foram distribuídos aleatoriamente em GAcetil, recebendo N-acetilcisteína por via intravenosa, 300mg/kg, e GIsot, solução salina. Foi realizada nefrectomia direita e clampeamento da artéria renal esquerda por 45 min. Os animais foram sacrificados após 48h, sendo colhidas amostras sanguíneas após a indução anestésica e ao sacrifício dos mesmos para avaliar a creatinina sérica. Realizou-se histologia renal. RESULTADOS: A variação da creatinina foi 2,33mg/dL ± 2,21 no GAcetil e 4,38mg/dL ± 2,13 no GIsot (p=0,074). Dois animais apresentaram necrose tubular intensa no GAcetil, comparados a cinco no GIsot. Apenas GAcetil apresentou animais livres de necrose tubular (dois) e degeneração tubular (um). CONCLUSÃO: Após isquemia/reperfusão renais, os ratos aos quais se administrou N-acetilcisteína apresentaram menor variação na creatinina sérica e lesões renais mais leves que o grupo controle.
