Prevalencia de desordenes musculo-esqueléticos y su asociación con factores ergonómicos en trabajadores administrativos de una institución educativa de nivel superior 2015

Objetivo. Establecer la prevalencia de Desordenes Musculo Esqueléticos(DME) y su asociación con factores ergonómicos (postura, manipulación de carga y trabajo repetitivo) en trabajadores administrativos de una Institución Educativa de Nivel Superior (IENS). Métodos. Se realizó un estudio descriptivo de corte transversal a 146 trabajadores de una IENS de la ciudad de Neiva (Huila), entre Abril y Mayo de 2015. Para la recolección de la información se utilizaron dos instrumentos: un instrumento para la caracterización sociodemográfica y ocupacional y el cuestionario estandarizado para identificar daños y exposición a riesgos ergonómicos en el trabajo (ERGOPAR). Resultados. El 90,4 % de los trabajadores presentaron molestia o dolor en alguna de las áreas del cuerpo, dentro de las cuales las más afectadas fueron las zonas del Cuello, hombros y/o espalda dorsal con el 79,9%, la espalda lumbar con el 65,8% y las manos y/o muñecas con el 49,3%. Conclusiones. Se encontró una asociación entre la exposición a factores ergonómicos y la presencia de DME, indicando que las posturas de trabajo forzadas o prolongadas y la manipulación de cargas representan un alto riesgo biomecánica para los trabajadores, lo cual se puede ver reflejado a mediano o largo plazo con el desarrollo de trastornos o enfermedades que pueden llegar a ser incapacitantes para los trabajadores, afectando su calidad de vida y su productividad laboral.

Aplicación del cuestionario nórdico para el análisis de síntomas musculoesqueleticos en trabajadores del Cuerpo Técnico de Policia Judicial: investigacion (CTI)

RESUMEN INTRODUCCION Los desórdenes musculoesqueléticos constituyen uno de los más comunes y costosos problemas de salud en el trabajo en todo el mundo. La detección a tiempo de síntomas iniciales debe ser una prioridad de los sistemas de vigilancia epidemiológica. El objetivo de este trabajo de investigación fue determinar la prevalencia de los desórdenes musculoesqueléticos (DME) en la población de funcionarios del cuerpo de policía judicial de Bogotá en el año 2014. MATERIALES Y METODOS Estudio de corte transversal con una muestra de 300 trabajadores a los que se les aplico el cuestionario Nórdico de Síntomas musculoesqueléticos. RESULTADOS Se encuesto al 33,9% de los trabajadores pertenecientes al cuerpo técnico de Policía Judicial de la Fiscalía General de la Nación en la ciudad de Bogotá. Los trabajadores evaluados tienen una edad promedio de 41,9 años, con un predominio del género femenino (54%), encontrándose que la mayoría de los que respondieron al cuestionario 87,66% (n=263) habían presentado algún síntoma musculoesqueléticos en los últimos 12 meses. Un hallazgo significativo fue la afectación cervical en el 53% (n=159) de los que reportaron sintomatología musculo esquelética. CONCLUSIONES La población perteneciente a la Policía Técnica Judicial en la ciudad de Bogotá presenta una alta prevalencia (87,66%) de síntomas que afectan al sistema musculoesquelético, principalmente comprometiendo las regiones de columna cervical, parte baja de la espalda y parte alta de la espalda, con una mayor afectación a las personas de género femenino.

Análisis de la ayuda oficial al desarrollo. estudio de caso: programa conjunto de UNICEF y UNFPA sobre la mutilación genital femenina en Kenia (2008-2012)

El interés de este estudio de caso es analizar el Programa Conjunto de UNFPA y UNICEF sobre MGF/E en Kenia bajo la luz de los postulados poscolonialistas. Partiendo de la idea de que la MGF es una manifestación de las desigualdades de género, se argumenta que el PC reproduce la imagen de la mujer keniana como una víctima del poder masculino. A partir de esta imagen se deslegitima el orden cultural de los grupos que siguen esta tradición, afectando las lógicas de unidad y cohesión de la sociedad. El análisis de este tipo de dinámicas permite comprender mejor los procesos de intervención de las organizaciones internacionales sobre las estructuras sociales de actores frágiles del sistema internacional.

Riesgo de accidentes biológicos en estudiantes de la salud: revisión de la literatura en los últimos 14 años.

Introducción: Todos los trabajadores del área de la salud están en riesgo de padecer un accidente biológico. No obstante los estudiantes de estas aéreas, pueden presentar más riesgo porque apenas están en formación y no tienen la práctica o experiencia suficiente. Existen varios artículos que han estudiado la incidencia y prevalencia de accidentes biológicos en los trabajadores del área de la salud, Sin embargo, sobre esta problemática de la población estudiantil del área de la salud, se encuentra menos literatura. Por lo tanto con esta revisión sistemática se busca analizar y actualizar este tema. Métodos: Se realizó una revisión de la literatura científica de artículos publicados en los últimos 14 años, en relación con la prevalencia de accidentes biológicos en estudiantes de medicina, odontología, enfermería y residentes del área de la salud a nivel mundial. Se llevó a cabo la búsqueda en la base de datos de Pubmed, encontrando un total de 100 artículos, escritos en inglés, francés, español o portugués. Resultados: Las prevalencias encontradas sobre accidentes biológicos en estudiantes fueron las siguientes: en países europeos a nivel de enfermería los valores oscilan entre 10.2 % a 32%, en medicina fueron del 16%-58.8%, y en odontología del 21 %. En países asiáticos, se encontró que en enfermería el porcentaje varía de 49%-96 %, en medicina van del 35% -68%, y en odontología varia de 68.a 75.4%. En Norte América, en medicina las cifras fluctúan alrededor del 11-72.7 % y en odontología giran alrededor del 19.1%. Finalmente respecto a Suramérica la prevalencia fue de 31.2 a 46.7% en medicina, y del 40% en enfermería. Conclusiones: Por lo anterior se pudo concluir que, la prevalencia de accidentes biológicos en los estudiantes del área de la salud es elevada y varía según el continente en el que se encuentren.

Prevalencia de síntomas musculo-esqueléticos en trabajadores de una institución de educación superior en el departamento de Arauca, Colombia, 2015

Introducción Los desórdenes musculo esqueléticos representan uno de los problemas de salud ocupacional más comunes de trabajadores, lo cual genera ausentismo laboral y aumento en los costos de enfermedades laborales. Objetivo Estimar la prevalencia de síntomas osteomusculares y su relación con factores de riesgo ocupacional, en personal docente y administrativo de una institución de educación superior en el Departamento de Arauca para el año 2015. Métodos Estudio analítico de corte transversal en una muestra de 116 trabajadores. Se utilizaron dos instrumentos: “La Encuesta Nacional de Condiciones de Trabajo” del Instituto Nacional de Seguridad e Higiene en el Trabajo de España (INSHT) y el “Cuestionario Ergopar”, validados al Español. Se obtuvo previa autorización del Comité de ética de la Universidad del Rosario. El análisis estadístico se realizó con el IBM SPSS Statistics versión 20.0. Resultados: Los síntomas osteomusculares con mayor prevalencia fueron en cuello (86,2%), espalda lumbar (61,2%), manos muñecas (59,5%) y pies (52,6%); no se observaron diferencias estadísticamente significantes entre administrativos e instructores. En el lugar de trabajo los factores de riesgo con mayor prevalencia fueron exposición a temperaturas extremas (48,3%), aberturas y huecos desprotegidos, escaleras, plataformas, desniveles (44%) significativamente mayor en instructores (52,6%) que en personal administrativo (27,5%) (p= 0,010). Conclusiones: Los síntomas osteomusculares más prevalentes fueron aquellos propios de la actividad docente: cuello, espalda lumbar, manos muñecas y pies. El personal de la institución en especial los docentes está expuesto a factores de riesgo físico, químico y ergonómico. Las condiciones de trabajo son adecuadas. No se encontró asociación estadística entre exposición a factores de riesgo en el puesto de trabajo y prevalencia de síntomas osteomusculares. Se debe establecer acciones dirigidas a evitar lesiones musculo esqueléticas en la población.

Asma ocupacional en peluquería: una revisión de la literatura

Este artículo pretende realizar una revisión de la literatura vigente acerca del asma ocupacional secundaria a la exposición de los factores de riesgo identificados en peluquería. Se realizó una búsqueda sistemática en las bases de datos PubMed y Cochrane de artículos de revistas indexadas con las palabras claves “Asthma occupational, hairdressers, hairdresser, work related asthma”. Aplicando los criterios de selección descritos, se revisaron 26 artículos en total donde se incluían reportes de casos, estudios de prevalencia, incidencia, corte transversa y revisiones, abarcando principalmente los temas de epidemiologia, fisiopatología, diagnóstico y prevención. Se agruparon según la metodología PRISMA para su respectiva comparación. Se concluyó que a pesar de la importancia de esta patología en el sector de peluquería, existen factores asociados como la informalidad del sector, la falta de estudios de investigación originales de cohorte o el desconocimiento de un protocolo claro de diagnóstico en este tipo de trabajadores, que limitan datos concluyentes acerca de la misma. Sin embargo, la mayoría de los autores concluye la relación entre la patología y la labor de peluquería, así falte esclarecer los mecanismos fisiopatológicos relacionados con los alérgenos identificados.

Artichoke leaf extract reduces symptoms of irritable bowel syndrome and improves quality of life in otherwise healthy volunteers suffering from concomitant dyspepsia: a subset analysis

Objectives: Does artichoke leaf extract (ALE) ameliorate symptoms of Irritable bowel syndrome (IBS) in otherwise healthy volunteers suffering concomitant dyspepsia? Methods: A subset analysis of a previous dose-ranging, open, postal study, in adults suffering dyspepsia. Two hundred and eight (208) adults were identified post hoc as suffering with IBS. IBS incidence, self-reported usual bowel pattern, and the Nepean Dyspepsia Index (NDI) were compared before and after a 2-month intervention period. Results: There was a significant fall in IBS incidence of 26.4% (p<0.001) after treatment. A significant shift in self-reported usual bowel pattern away from "alternating constipation/diarrhea" toward "normal" (p<0.001) was observed. NDI total symptom score significantly decreased by 41% (p<0.001) after treatment. Similarly, there was a significant 20% improvement in the NDI total quality-of-life (QOL) score in the subset after treatment. Conclusion: This report supports previous findings that ALE ameliorates symptoms of IBS, plus improves health-related QOL.

Cost-benefit evaluation of routine influenza immunisation in people 65-74 years of age

OBJECTIVES: To determine the cost-effectiveness of influenza vaccination in people aged 65-74 years in the absence of co-morbidity. DESIGN: Primary research: randomised controlled trial. SETTING: Primary care. PARTICIPANTS: People without risk factors for influenza or contraindications to vaccination were identified from 20 general practitioner (GP) practices in Liverpool in September 1999 and invited to participate in the study. There were 5875/9727 (60.4%) people aged 65-74 years identified as potentially eligible and, of these, 729 (12%) were randomised. INTERVENTION: Participants were randomised to receive either influenza vaccine or placebo (ratio 3:1), with all individuals receiving pneumococcal vaccine unless administered in the previous 10 years. Of the 729 people randomised, 552 received vaccine and 177 received placebo; 726 individuals were administered pneumococcal vaccine. MAIN OUTCOME MEASURES AND METHODOLOGY OF ECONOMIC EVALUATION: GP attendance with influenza-like illness (ILI) or pneumonia (primary outcome measure); or any respiratory symptoms; hospitalisation with a respiratory illness; death; participant self-reported ILI; quality of life (QoL) measures at 2, 4 and 6 months post-study vaccination; adverse reactions 3 days after vaccination. A cost-effectiveness analysis was undertaken to identify the incremental cost associated with the avoidance of episodes of influenza in the vaccination population and an impact model was used to extrapolate the cost-effectiveness results obtained from the trial to assess their generalisability throughout the NHS. RESULTS: In England and Wales, weekly consultations for influenza and ILI remained at baseline levels (less than 50 per 100,000 population) until week 50/1999 and then increased rapidly, peaking during week 2/2000 with a rate of 231/100,000. This rate fell within the range of 'higher than expected seasonal activity' of 200-400/100,000. Rates then quickly declined, returning to baseline levels by week 5/2000. The predominant circulating strain during this period was influenza A (H3N2). Five (0.9%) people in the vaccine group were diagnosed by their GP with an ILI compared to two (1.1%) in the placebo group [relative risk (RR), 0.8; 95% confidence interval (CI) = 0.16 to 4.1]. No participants were diagnosed with pneumonia by their GP and there were no hospitalisations for respiratory illness in either group. Significantly fewer vaccinated individuals self-reported a single ILI (4.6% vs 8.9%, RR, 0.51; 95% CI for RR, 0.28 to 0.96). There was no significant difference in any of the QoL measurements over time between the two groups. Reported systemic side-effects showed no significant differences between groups. Local side-effects occurred with a significantly increased incidence in the vaccine group (11.3% vs 5.1%, p = 0.02). Each GP consultation avoided by vaccination was estimated from trial data to generate a net NHS cost of 174 pounds. CONCLUSIONS: No difference was seen between groups for the primary outcome measure, although the trial was underpowered to demonstrate a true difference. Vaccination had no significant effect on any of the QoL measures used, although vaccinated individuals were less likely to self-report ILI. The analysis did not suggest that influenza vaccination in healthy people aged 65-74 years would lead to lower NHS costs. Future research should look at ways to maximise vaccine uptake in people at greatest risk from influenza and also the level of vaccine protection afforded to people from different age and socio-economic populations.

A follow-up study of characteristics of young people that dropout and continue psychotherapy: service implications for a clinic in the community

Background: The paper reports the findings from a follow-up study of the factors that contribute to whether young people dropout or continue once-weekly psychotherapy at a voluntary sector psychotherapy service for young people aged 12 to 21 years. Method: The study uses data from an ongoing audit of the psychotherapy service that started in 1993; 882 young people were included in the study. Premature termination of treatment was defined as dropping out before the 21st session. Continuation in treatment was defined as remaining in therapy after 20 sessions. Measures and areas of interest used in the study include diagnostic measures, the Youth Self Report Form and Young Adult Self Report Form, demographic characteristics and treatment related information. Results: Young people who continued in treatment were more likely to be older, have anxieties about sexual and relationship issues and have higher scores on self-reported anxiety-depression. Young people who dropped out of treatment were more likely to be younger, have higher self-reported delinquency scores, have a diagnosis of hyperactivity-conduct disorder and be homeless. Conclusions: The study of treatment termination has demonstrated the value of service audit and has led to a significant change in clinical practice.

Infant Attachment Security and the Timing of Puberty: Testing an Evolutionary Hypothesis

Life-history theories of the early programming of human reproductive strategy stipulate that early rearing experience, including that reflected in infant-parent attachment security, regulates psychological, behavioral, and reproductive development. We tested the hypothesis that infant attachment insecurity, compared with infant attachment security, at the age of 15 months predicts earlier pubertal maturation. Focusing on 373 White females enrolled in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, we gathered data from annual physical exams from the ages of 9½ years to 15½ years and from self-reported age of menarche. Results revealed that individuals who had been insecure infants initiated and completed pubertal development earlier and had an earlier age of menarche compared with individuals who had been secure infants, even after accounting for age of menarche in the infants’ mothers. These results support a conditional-adaptational view of individual differences in attachment security and raise questions about the biological mechanisms responsible for the attachment effects we discerned.

The Huntington's Disease health-related Quality of Life questionnaire (HDQoL): a disease-specific measure of health-related quality of life

Hocaoglu MB, Gaffan EA, Ho AK. The Huntington's disease health-related quality of life questionnaire: a disease-specific measure of health-related quality of life. Huntington's disease (HD) is a genetic neurodegenerative disorder characterized by motor, cognitive and psychiatric disturbances, and yet there is no disease-specific patient-reported health-related quality of life outcome measure for patients. Our aim was to develop and validate such an instrument, i.e. the Huntington's Disease health-related Quality of Life questionnaire (HDQoL), to capture the true impact of living with this disease. Semi-structured interviews were conducted with the full spectrum of people living with HD, to form a pool of items, which were then examined in a larger sample prior to data-driven item reduction. We provide the statistical basis for the extraction of three different sets of scales from the HDQoL, and present validation and psychometric data on these scales using a sample of 152 participants living with HD. These new patient-derived scales provide promising patient-reported outcome measures for HD.

Physical activity attenuates the body mass index-increasing influence of genetic variation in the FTO gene 1-3.

BACKGROUND: Intronic variation in the FTO (fat mass and obesity-associated) gene has been unequivocally associated with increased body mass index (BMI; in kg/m(2)) and the risk of obesity in populations of different ethnicity. OBJECTIVE: We examined whether this robust genetic predisposition to obesity can be attenuated by being more physically active. DESIGN: The FTO variant rs1121980 was genotyped in 20,374 participants (39-79 y of age) from the European Prospective Investigation into Cancer and Nutrition-Norfolk Study, an ethnically homogeneous population-based cohort. Physical activity (PA) was assessed with a validated self-reported questionnaire. The interaction between rs1121980 and PA on BMI and waist circumference (WC) was examined by including the interaction term in mixed-effect models. RESULTS: We confirmed that the risk (T) allele of rs1121980 was significantly associated with BMI (0.31-unit increase per allele; P < 0.001) and WC (0.77-cm increase per allele; P < 0.001). The PA level attenuated the effect of rs1121980 on BMI and WC; ie, whereas in active individuals the risk allele increased BMI by 0.25 per allele, the increase in BMI was significantly (P for interaction = 0.004) more pronounced (76%) in inactive individuals (0.44 per risk allele). We observed similar effects for WC (P for interaction = 0.02): the risk allele increased WC by 1.04 cm per allele in inactive individuals but by only 0.64 cm in active individuals. CONCLUSIONS: Our results showed that PA attenuates the effect of the FTO rs1121980 genotype on BMI and WC. This observation has important public health implications because we showed that a genetic susceptibility to obesity induced by FTO variation can be overcome, at least in part, by adopting a physically active lifestyle.

Association between sucrose intake and risk of overweight and obesity in a prospective sub-cohort of EPIC-Norfolk

Objective: The objective of this study was to investigate associations between sugar intake and overweight using dietary biomarkers in the Norfolk cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Norfolk). Design: Prospective cohort study Setting: European Prospective Investigation into Cancer in Norfolk (EPIC-Norfolk) in the UK, recruitment between 1993 and 1997. Subjects: 1734 participants (39 – 77 years). Sucrose intake was assessed using 7-day diaries. Baseline spot urine samples were analysed for sucrose by GC-MS. Sucrose concentration adjusted by specific gravity was used as biomarker for intake. Regression analyses were used to investigate associations between sucrose intake and risk of BMI > 25 kg/m2 after three years of follow-up. Results: After three years of follow-up, mean BMI was 26.8 kg/m2. Self-reported sucrose intake was significantly positively associated with biomarker. Associations between biomarker and BMI were positive (β=0.25; 95% CI: 0.08; 0.43), while they were inverse when using self-reported dietary data (β=-1.40; 95% CI: -1.81; -0.99). Age- and sex-adjusted OR for BMI > 25 kg/m2 in participants in the fifth vs. first quintile was 1.54 (95% CI: 1.12; 2.12; pTrend=0.003,) when using biomarker and 0.56 (95% CI: 0.40; 0.77; pTrend<0.001) with self-reported dietary data. Conclusions: Our results suggest that sucrose measured by objective biomarker but not self-reported sucrose intake is positively associated with body mass index. Future studies should consider use of objective biomarkers of sucrose intake.

Xylo-oligosaccharides alone or in synbiotic combination with Bifidobacterium animalis subsp. lactis induce bifidogenesis and modulate markers of immune function in healthy adults: a double-blind, placebo-controlled, randomised, factorial cross-over study.

Prebiotics, probiotics and synbiotics are dietary ingredients with the potential to influence health and mucosal and systemic immune function by altering the composition of the gut microbiota. In the present study, a candidate prebiotic (xylo-oligosaccharide, XOS, 8 g/d), probiotic (Bifidobacterium animalis subsp. lactis Bi-07, 109 colony-forming units (CFU)/d) or synbiotic (8 g XOS+109 CFU Bi-07/d) was given to healthy adults (25–65 years) for 21 d. The aim was to identify the effect of the supplements on bowel habits, self-reported mood, composition of the gut microbiota, blood lipid concentrations and immune function. XOS supplementation increased mean bowel movements per d (P= 0·009), but did not alter the symptoms of bloating, abdominal pain or flatulence or the incidence of any reported adverse events compared with maltodextrin supplementation. XOS supplementation significantly increased participant-reported vitality (P= 0·003) and happiness (P= 0·034). Lowest reported use of analgesics was observed during the XOS+Bi-07 supplementation period (P= 0·004). XOS supplementation significantly increased faecal bifidobacterial counts (P= 0·008) and fasting plasma HDL concentrations (P= 0·005). Bi-07 supplementation significantly increased faecal B. lactis content (P= 0·007), lowered lipopolysaccharide-stimulated IL-4 secretion in whole-blood cultures (P= 0·035) and salivary IgA content (P= 0·040) and increased IL-6 secretion (P= 0·009). XOS supplementation resulted in lower expression of CD16/56 on natural killer T cells (P= 0·027) and lower IL-10 secretion (P= 0·049), while XOS and Bi-07 supplementation reduced the expression of CD19 on B cells (XOS × Bi-07, P= 0·009). The present study demonstrates that XOS induce bifidogenesis, improve aspects of the plasma lipid profile and modulate the markers of immune function in healthy adults. The provision of XOS+Bi-07 as a synbiotic may confer further benefits due to the discrete effects of Bi-07 on the gut microbiota and markers of immune function.

Risks Associated With Tendinitis: Effects From Demographic, Socioeconomic, and Psychological Status Among Brazilian Workers

Background Self-reported tendinitis/tenosynovitis was evaluated by gender, age group, skin color, family income, and educational and psychological status. Methods The study was carried out in a representative sample of formally contracted Brazilian workers from a household survey. A total of 54,660 participants were included. Occupations were stratified according to estimated prevalences of self-reported injuries. Non-conditional logistic regression was performed, and all variables were analyzed in two occupational groups. Results The overall prevalence rate of tendinitis/tenosynovitis was 3.1%: 5.5% in high-prevalence occupations (n=10,726); and 2.5% in low-prevalence occupations (n=43,934). White female workers between the ages of 45 and 64 years and at a higher socioeconomic level were more likely to report tendinitis/tenosynovitis regardless of their occupational category. An adjusted OR = 3.59 [95% CI: 3.15-4.09] was found between tendinitis/tenosynovitis and psychological status. Conclusion Among formally contracted Brazilian workers, higher income can imply greater physical and psychological demands that, regardless of occupational stratum, increase the risk of tendinitis/tenosynovitis.
