The association between obesity and back pain in nine countries: a cross-sectional study

BACKGROUND: The association between obesity and back pain has mainly been studied in high-income settings with inconclusive results, and data from older populations and developing countries are scarce. The aim of this study was to assess this association in nine countries in Asia, Africa, Europe, and Latin America among older adults using nationally-representative data. METHODS: Data on 42116 individuals ≥50 years who participated in the Collaborative Research on Ageing in Europe (COURAGE) study conducted in Finland, Poland, and Spain in 2011-2012, and the World Health Organization's Study on Global Ageing and Adult Health (SAGE) conducted in China, Ghana, India, Mexico, Russia, and South Africa in 2007-2010 were analysed. Information on measured height and weight available in the two datasets was used to calculate Body Mass Index (BMI). Self-reported back pain occurring in the past 30 days was the outcome. Multivariable logistic regression analysis was used to assess the association between BMI and back pain. RESULTS: The prevalence of back pain ranged from 21.5% (China) to 57.5% (Poland). In the multivariable analysis, compared to BMI 18.5-24.9 kg/m(2), significantly higher odds for back pain were observed for BMI ≥35 kg/m(2) in Finland (OR 3.33), Russia (OR 2.20), Poland (OR 2.03), Spain (OR 1.56), and South Africa (OR 1.48); BMI 30.0-34.0 kg/m(2) in Russia (OR 2.76), South Africa (OR 1.51), and Poland (OR 1.47); and BMI 25.0-29.9 kg/m(2) in Russia (OR 1.51) and Poland (OR 1.40). No significant associations were found in the other countries. CONCLUSIONS: The strength of the association between obesity and back pain may vary by country. Future studies are needed to determine the factors contributing to differences in the associations observed.

Role of technetium-99m diphosphonate and gallium-67 citrate bone scanning in the early diagnosis of infectious spondylodiscitis: a comparative study

A comparative study of the parts played by technetium-99m diphosphonate and gallium-67 citrate bone scanning in the early diagnosis of infectious spondylodiscitis is presented. Nineteen patients were included in the study. All patients (11 men aged 19-70 years and eight women aged 18-72 years) had a history of back pain varying in duration from one to 15 weeks. A 99mTc diphosphonate bone scan was positive in 17 patients. The two patients with negative results had less than two weeks of back pain. The 67Ga citrate bone scan showed uptake in all patients.

Comparació entre dos mètodes d'estiraments ; estàtic i dinàmic, realitzats en l'escalfament de curses i entrenaments de 60, 100 i 110 metres tanques

Aquest estudi es basa en l'idea de que l'escurçament de la cadena musuclar posterior és una causa important del mal d'esquena en nens. És per aquest motiu que es planteja un tractament per a prevenir l'escurçament de la cadena muscular posterior i el mal d'esquena en forma de sessions de Stretching Global Actiu, mètode basat en la Reeducació Postural Global del mateix Ph.E. Souchard, que es posarà en pràctica en 3 escoles diferents de la comarca d'Osona. L'estudi té una durada de 3 cursos escolars (3r, 4t i 5è de primària) en el qual els nens seleccionats per al grup experimental (n=30) realitzaran classes de Stretching Global Actiu dues vegades a la setmana durant 3 mesos en cada curs escolar. Tres escoles més formaran el grup control (n=30) i s'espera que els nens que formen part del grup experimental millorin la flexibilitat de la cadena musuclar posterior (això es podrà observar a través dels resultats del test "sit and reach") i que no presentin mal d'esquena en el transcurs de 3 anys (durada de l'estudi).

What works best for getting the unemployed back to work: employment services or small-business assistance programs? evidence from Romania

Recent empirical evidence has found that employment services and small-business assistance programmes are often successful at getting the unemployed back to work. Â One important concern of policy makers is to decide which of these two programmes is more effective and for whom. Â Using unusually rich (for transition economies) survey data and matching methods, I evaluate the relative effectiveness of these two programmes in Romania. Â While I find that employment services (ES) are, on average, more successful than a small-business assistance programme (SBA), estimation of heterogeneity effects reveals that, compared to non-participation, ES are effective for workers with little access to informal search channels, and SBA works for less-qualified workers and those living in rural areas. Â When comparing ES to SBA, I find that ES tend to be more efficient than SBA for workers without a high-school degree, and that the opposite holds for the more educated workers.

El Théâtre de La Mie de Pain, un exemple del teatre de l’actor-creador

L’autora del treball, Élisabeth Cauchetiez, va formar part del grup Théâtre de La Mie de Pain des del setembre 1979 al febrer 1989, La intenció de la recerca és de fer de l’experiència subjectiva un objecte d’observació. Desprès de definir què és el teatre de l’actor creador, en un moment de la història del teatre on la creació col•lectiva va assolir la dimensió de fascinació. fa esment als fonaments sociològics del Théâtre de La Mie de Pain i analitza les programacions dels festivals i gires, així com la recepció que la crítica teatral va fer dels seus espectacles. Explica el procés d’elaboració dels espectacles : “Blanche-Neige au royaume de Fantochie”, “Séance-Friction”, “Seul ... Les requins ! “, “Terminus Hôpital ” i “Starjob”.

Biofeedback : retroalimentación electroencefalográfica : estudio de la efectividad de la adopción de patrones neuronales por entrenamiento para paliar el dolor

S’ha demostrat que la pràctica d'estats de relaxació profunda redueix el dolor i incrementa el benestar i la qualitat de vida. Els estats de relaxació profunda i meditació estan al seu torn associats a patrons electroencefalogràfics (EEG) característics. En el present projecte proposem un procediment pal·liatiu del dolor basat en l 'entrenament autodidàctic per aconseguir aquests estats de relaxació. Per a això es proposa retro-alimentar al subjecte un senyal auditiu reflex de la seva activitat EEG que l'ajudi a modificar voluntàriament la seva activitat cerebral, la qual cosa li permet aproximar-la progressivament al patró EEG corresponent al de relaxació profunda desitjat. S’ha dissenyat un protocol d'entrenament d'estats mentals de relaxació i meditació (entre altres) i implementat un programa que processa el senyal EEG i genera un senyal auditiu reflex de l'activitat cerebral de l'individu. També registra les lectures EEG del progrés de l'individu, genera les gràfiques corresponents i genera dades estadístiques per a futur anàlisi.

Exploring the conditions for a mortality crisis: bringing context back into the debate

This study engages with the debate over the mortality crises in the former Soviet Union and Central and Eastern Europe by 1) considering at length and as complementary to each other the two most prominent explanations for the post-communist mortality crisis, stress and alcohol consumption; 2) emphasizing the importance of context by exploiting systematic similarities and differences across the region. Differential mortality trajectories reveal three country groups that cluster both spatially and in terms of economic transition experiences. The first group are the countries furthest west in which mortality rates increased minimally after the transition began. The second group experienced a severe increase in mortality rates in the early 1990s, but recovered previous levels within a few years. These countries are located peripherally to Russia and its nearest neighbours. The final group consists of countries that experienced two mortality increases or in which mortality levels had not recovered to pre-transition levels well into the 21st century. Cross-sectional time-series data analyses of men’s and women’s age and cause-specific death rates reveal that the clustering of these countries and their mortality trajectories can be partially explained by the economic context, which is argued to be linked to stress and alcohol consumption. Above and beyond many basic differences in the country groups that are held constant—including geographically and historically shared cultural, lifestyle and social characteristics—poor economic conditions account for a remarkably consistent share of excess age-specific and cause-specific deaths.
