La presa de consciència de les actituds a l'educació física en la formació inicial de mestres de primària

Aquest treball és el resultat d’un procés de reflexió al voltant de les actituds dins la Formació Inicial de mestres de primària d’Educació física. Es tracta, d’una primera aproximació d’anàlisi i interpretació sobre la presa de consciència d’actituds que fan els estudiants en la pràctica de l’Educació física. Les preguntes que em plantejo en aquesta recerca són el resultat de les dues parts que configura aquest treball. La primera pregunta, es centra en el marc teòric de l’estudi, donant resposta a les relacions que s’estableixen entre l’educació física i l’educació en valors en el currículum de primària d’Educació física i en la Formació Inicial de mestres. La segona pregunta, pretén donar resposta a la proposta pràctica i així, esbrinar el paper del joc motor en el treball educatiu de les actituds en la Formació Inicial de mestres de primària. Els aspectes teòrics que estudio analitzen la relació que s’estableix entre l’Educació física i les actituds dins el marc educatiu de la Formació Inicial de mestres de primària. I serà, a partir de la proposta pràctica quan el joc motor esdevindrà element d’aproximació en la presa de consciència d’actituds En el context de la Facultat d’Educació de la Universitat de Vic, i en l’assignatura d’Educació física i la seva Didàctica de 2n curs, els estudiants de mestres de primària d’Educació física són protagonistes del seu propi procés d’aprenentatge. Tenen la possibilitat d’experimentar el paper de mestres, a partir de la posada en pràctica d’un joc motor. A partir d’aquesta pràctica, he volgut conèixer quins són els components de la pràctica que possibiliten la presa de consciència de les actituds presents a les sessions de classe per promoure l’educació en valors. Els instruments utilitzats, en la realització d’aquest treball, són un qüestionari elaborat a partir d’una selecció i justificació de continguts actitudinals, i l’observació d’una fitxa sessió després de la pràctica. El treball de recerca se situa en un paradigma interpretatiu i pràctic. Es planteja comprendre la importància que té, en les sessions de classe d’educació física, el desenvolupament de processos d’acció i de reflexió en la formació inicial dels mestres de primària i així examinar i perfeccionar futures intervencions pràctiques, tant del professorat com dels estudiants de mestre.

La réhabilitation psychosociale a l'aube du XXIème siècle: III: Méthode d'évaluation interdisciplinaire et bilan biopsycho-social

During the past 20 years, therapeutic and rehabilitative modalities in the field of psychosocial rehabilitation have been diversified in becoming more specific. We have the possibility to offer individualized rehabilitation programs as well as in the general field of socio-professional goals as in the clinical field according to the patients' needs and personal assets. The content of these programs associates various forms of specialized medical and paramedical services. The indications are established trough a careful assessment. The rehabilitation unit of the University Department of Psychiatry in Lausanne has developed a multidisciplinary assessment method based on the bio-psychosocial integrative model and the vulnerability-stress model in integrating the level of experience of Wood for the analysis of the psychosocial functioning. This results in a structured assessment program, which leads to a multidisciplinary comprehensive assessment (difficulties versus adaptative resources)

Work, risk and health: differences between immigrants and natives in Spain

We analyze the impact of working and contractual conditions, particularly exposure to job risks, on the probability of acquiring a disability. We postulate a model in which this impact is mediated by the choice of occupation, with a level of risk associated to it. We assume this choice is endogenous, and that it depends on preferences and opportunities in the labour market, both of which may differ between immigrants and natives. To test this hypothesis we use data from the Continuous Sample of Working Lives of the Spanish SS system. It contains individual, job and firm information of over a million workers, including a representative sample of immigrants. We find that risk exposure increases the probability of permanent disability by 5.3%; temporary employment also influences health. Migrant status -with differences among regions of origin- significantly affects both disability and the probability of being employed in a risky occupation. Most groups of immigrants work in riskier jobs, but have lower probability of becoming disabled. Nevertheless, our theoretical hypothesis that disability and risk are jointly determined is not valid for immigrants: i.e. for them working conditions is not a matter of choice in terms of health.

Pilot study of induction chemotherapy followed by concomitant chemotherapy and IMRT or tomotherapy for nasopharyngeal carcinoma

Objective: Standard treatment of locally advanced (stages III and IV A-B) nasopharyngeal carcinoma (NPC) consists in chemoradiotherapy with 5-y survival rates of around 60%. However, acute toxicity prevents the administration of adequate adjuvant chemotherapy in nearly half of the patients. This situation has led to the hypothesis that induction chemotherapy followed by chemoradiotherapy may be a superior approach. Many ongoing studies are testing the role of induction chemotherapy in this setting. Newer radiotherapy techniques are becoming available (intensity modulated radiotherapy [IMRT] and tomotherapy). They can achieve a higher degree of accuracy in conforming the radiation to the planned target volume while sparing normal tissue resulting in less acute and long-term toxicity. Methods: We report here our local experience of 11 consecutive locally advanced NPC patients treated between June 2004 and October 2007. Median age was 46 years (range, 17-65). All but one were male patients. Initial stage was stage III in 5, and stage IVA-B in 6 patients. Treatment consisted of 3 cycles of induction TCF (Docetaxel 75 mg/m2- Cisplatin 75 mg/m2- 5-fluorouracil 750 mg/m2/d 5 days) chemotherapy followed by concomitant chemoradiotherapy with 3 cycles of cisplatin (100 mg/m2), or carboplatin (AUC 5) in case of renal impairment. Radiotherapy was delivered by either IMRT or tomotherapy. Macroscopic disease (tumor + involved lymph nodes) was treated with 70 Gy, 2 Gy/fraction (IMRT), or 69.6 Gy, 1.12 Gy/fraction (simultaneus integrated boost [SIB] technique). Elective nodal irradiation of 46-54 Gy lymph was performed in all patients, whereas elective irradiation of the entire nasopharynx (60 Gy) half of patients. Results: All but one tumor were EBV positive. Induction chemotherapy was done as planned for 8 patients (73%). Two patients had only 2 cycles, 1 patient had only1 cycle of TCF, and the other without docetaxel. Concomitant chemotherapy was given as planned in 7 patients (64%). Four patients had only 2 cycles. Radiotherapy could be delivered as planned in all patients. Eight weeks post treatment all patients proved to have a CR (CR or uCR). After a median follow-up of 11 months (range, 6-38 months) only one patient has relapsed. Details on acute and 1 year toxicities will be presented. Conclusion: Treatment of locally advancedNPC with induction and concomitant chemotherapy is feasible and well tolerated. The use of IMRT or tomotherapy technique seems to ameliorate the therapeutic index particularly in regard with xerostomia. All our patients presented a complete response. For the assessment of survival and long-term toxicity, a longer follow-up period is needed.

The role of interleukin-5 (IL-5 ) in vivo: studies with IL-5 deficient mice

Eosinophil recruitment is a characteristic feature of a number of pathological conditions and was the topic of the recent International Symposium on allergic inflammation, asthma, parasitic and infectious diseases (Rio de Janeiro, June 3-5, 1996). Since interleukin5 (IL5) is believed to regulate the growth, differentiation and activation of eosinophils (Coffman et al. 1989, Sanderson 1992), the role of eosinophils and IL5 are closely linked. Although IL5 specifically regulates eosinophilia in vivo and this is its most well established activity, it is becoming clear that IL5 also has other biological effects. The recent derivation of an IL5 deficient mouse (Kopf et al. 1996), provides a model for exploring not only the role of IL5 and eosinophils but also other novel activities of IL5. Of note is that although the IL5 deficient mice cannot elicit a pronounced eosinophilia in response to inflammatory stimulation following aeroallergen challenge or parasite infection they still produce basal levels of eosinophils that appear to be morphologically and functionally normal. However, the basal levels of eosinophils appear insufficient for normal host defence as IL5 deficiency has now been shown to compromise defence against several helminth infections. In addition, IL5 deficient mice appear to have functional deficiencies in B-1 B lymphocytes and in IgA production.

Eimeria peltocephali n. sp., (Apicomplexa:Eimeriidae) from the Freshwater Turtle Peltocephalus dumerilianus (Chelonia:Pelomusidae) and Eimeria molossi n. sp., from the Bat, Molossus ater (Mammalia:Chiroptera)

The oocyst is described of Eimeria peltocephali n.sp. from faeces of the freshwater turtle Peltocephalus dumerilianus from Barcelos, State of Amazonas, Brazil. Sporulation is exogenous and fully developed oocysts are elongate, ellipsoidal or cylindrical, frequently curved to a banana-shape, 54.4 x19.1 (37.5 - 68.7 x 18.7-20.0 µm), shape-index 2.8 (1.8 -3.9). The oocyst wall is a single thin, colourless layer about 1 µm thick, with no micropyle. There is a bulky oocyst residuum, at first spherical to ellipsoidal, 19 x 16 (16. 2 -26.2 x 16 - 21.5µm) , but becoming dispersed on maturation. There are no polar bodies. The sporocysts, 19.1 x 6.8 ( 17.5 -21.2 x 6.2 -7.5 µm), shape- index 2.8 (2.3 -3.2), are usually disposed in pairs at each end of the oocyst, and bear an inconspicuous Stieda body in the form of a flat cap. The sporozoites are elongate and slightly curved around the residuum. No refractile bodies were seen. Eimeria molossi n.sp., is described from the molossid bat Molossus ater. Sporulation is exogenous and the mature oocysts are predominantly broadly ellipsoidal, 23.4 x 17.5 (18-30 x 15-22.5 µm), shape-index 1.3 (1-1.6). The oocyst wall is about 2 µm thick, and of three layers: an inner thin, colourless one and two outer layers which are thicker, yellowish-brown, prominently striated and in close apposition. There is no micropyle or oocyst residuum, but one and occasionally two polar bodies are usually present. Sporocysts are ellipsoidal, 10.2 x 7.5 (10-12.5 x 7.5 µm), shape-index 1.4 (1.3-1.7) with an inconspicuous Stieda body. Endogenous stages are described in the epithelial cells of the small intestine

Obedience-disobedience dynamic and the role of responsibility

Obedience has been thoroughly studied in social psychology, both in its positive and negative aspects. Nevertheless, in these empirical studies disobedience has been considered to be the opposite of obedience and indeed its negation. Instead, some recent studies suggest that if obedience to authority is important in ensuring the continuity of social and group life, disobedience is crucial, under some circumstances, in stopping the authority relationship from degenerating into an authoritarian relationship. In this perspective, disobedience may be conceived of as a protest undermining the legitimacy of authority, or else it can represent an instrument of the community for controlling the legitimacy of the authority's demands, becoming a factor safeguarding against authoritarianism. The aim of the present study was to empirically verify the dynamics existing between disobedience and obedience. The results show that people who attach importance to both obedience and disobedience in the relationship between the individual and society recognize the importance of democratic values and consider themselves responsible for the defence of human rights. Instead, people who only recognize the value of obedience and consider disobedience as a threat to the status quo are more authoritarian, individualistic people.

Molecular Epidemiology and Emergence of Rift Valley Fever

Rift Valley fever (RVF) is a mosquito-borne viral disease which manifested itself during recent epidemics and revealed its significant potential of emergence. Studies on molecular epidemiology undertaken to better understand the factors leading to RVF emergence, have confirmed the mode of circulation of the virus and highlithted probable risks and obstacles for prevention and control. As for several other viral agents, molecular epidemiology is becoming a useful tool in the study of the emergence of RVF as a serious infectious disease.

Fauna silvestre del Parc del Garraf. Afectacions al sector primari

El Parc del Garraf (PG) ha estat tradicionalment una important zona agrícola, encara que actualment és molt reduïda (representa el 3% del total de la superfície del parc) i està repartida entre unes poques masies. Aquesta activitat humana conviu amb la fauna silvestre de la zona, que en alimentar-se parcialment dels cultius (cereal, vinya, oliveres, arbres fruiters i hortalisses), hi causa diversos impactes. És el cas de diverses aus, com ara la garsa (Pica Pica) i el pardal (Passer domesticus), i també d’alguns mamífers com el porc senglar (Sus scrofa). Hem observat que l’impacte produït per les aus i el porc senglar (Sus scrofa) és molt petit, el que pot ser degut a dos motius principals: possiblement per una elevada producció de fruits salvatges, esdevenint aquest aliment suficient per a les aus; i la baixa densitat poblacional de porc senglar (Sus scrofa) al parc. Els impactes observats presenten una alta variabilitat i depenen de l’època de l’any en que ens trobem. Per tant, cal fer-ne un seguiment més acurat on s’impliquin administració i pagesos per a millorar el coneixement de l’impacte de la fauna salvatge.

The nuclear matrix: a critical appraisal.

It is becoming increasingly clear that the cell nucleus is a highly structurized organelle. Because of its tight compartmentalization, it is generally believed that a framework must exist, responsible for maintaining such a spatial organization. Over the last twenty years many investigations have been devoted to identifying the nuclear framework. Structures isolated by different techniques have been obtained in vitro and are variously referred to as nuclear matrix, nucleoskeleton or nuclear scaffold. Many different functions, such as DNA replication and repair, mRNA transcription, processing and transport have been described to occur in close association with these structures. However, there is still much debate as to whether or not any of these preparations corresponds to a nuclear framework that exists in vivo. In this article we summarize the most commonly-used methods for obtaining preparations of nuclear frameworks and we also stress the possible artifacts that can be created in vitro during the isolation procedures. Emphasis is placed also on the protein composition of the frameworks as well as on some possible signalling functions that have been recently described to occur in tight association with the nuclear matrix.

Are virtual planning and guided surgery for head and neck reconstruction economically viable?

PURPOSE: Virtual planning and guided surgery with or without prebent or milled plates are becoming more and more common for mandibular reconstruction with fibular free flaps (FFFs). Although this excellent surgical option is being used more widely, the question of the additional cost of planning and cutting-guide production has to be discussed. In capped payment systems such additional costs have to be offset by other savings if there are no special provisions for extra funding. Our study was designed to determine whether using virtual planning and guided surgery resulted in time saved during surgery and whether this time gain resulted in self-funding of such planning through the time saved. MATERIALS AND METHODS: All consecutive cases of FFF surgery were evaluated during a 2-year period. Institutional data were used to determine the price of 1 minute of operative time. The time for fibula molding, plate adaptation, and insetting was recorded. RESULTS: During the defined period, we performed 20 mandibular reconstructions using FFFs, 9 with virtual planning and guided surgery and 11 freehand cases. One minute of operative time was calculated to cost US $47.50. Multiplying this number by the time saved, we found that the additional cost of virtual planning was reduced from US $5,098 to US $1,231.50 with a prebent plate and from US $6,980 to US $3,113.50 for a milled plate. CONCLUSIONS: Even in capped health care systems, virtual planning and guided surgery including prebent or milled plates are financially viable.

Annual Update on Fuel Poverty and Health (2008)

This paper provides an update on the All-Ireland Policy Paper on Fuel Poverty and Health published by the Institute of Public Health in Ireland (IPH) in December 2007.Economic downturn and fluctuating fuel prices mean that for many people the challenge of fuel poverty is becoming even more immediate. Alleviating financial strain and protecting the health and social well-being of fuel-poor householders must remain a priority across government. A substantial body of research links fuel poverty to physical and mental ill-health. Older people in particular are at an increased risk of suffering from heart disease, stroke and respiratory conditions in the winter months. Research published in Northern Ireland this year has also highlighted the impact of fuel poverty on children’s health and well-being.  

Potential exposure to hepatitis C virus through accidental blood contact in interventional radiology.

PURPOSE: To quantify the prevalence of accidental blood exposure (ABE) among interventional radiologists and contrast that with the prevalence of patients with hepatitis C virus (HCV) undergoing interventional radiology procedures. MATERIALS AND METHODS: A multicenter epidemiologic study was conducted in radiology wards in France. The risk of ABE to radiologists was assessed based on personal interviews that determined the frequency and type of ABE and the use of standard protective barriers. Patients who underwent invasive procedures underwent prospective sampling for HCV serologic analysis. HCV viremia was measured in patients who tested positive for HCV. RESULTS: Of the 77 radiologists who participated in 11 interventional radiology wards, 44% reported at least one incident of mucous membrane blood exposure and 52% reported at least one percutaneous injury since the beginning of their occupational activity. Compliance with standard precautions was poor, especially for the use of protective clothes and safety material. Overall, 91 of 944 treated patients (9.7%) tested positive for HCV during the study period, of whom 90.1% had positive viremia results, demonstrating a high potential for contamination through blood contacts. CONCLUSIONS: The probability of HCV transmission from contact with contaminated blood after percutaneous injury ranged from 0.013 to 0.030; the high frequency of accidental blood exposure and high percentage of patients with HCV could generate a risk of exposure to HCV for radiologists who perform invasive procedures with frequent blood contact. The need to reinforce compliance with standard hygiene precautions is becoming crucial for medical and technical personnel working in these wards.

Extra healthy years or just extra years? What can we know from the data we have on the island of Ireland?

As life expectancy continues to rise, the prevalence of chronic conditions is increasing in our society. However, we do not know if the extra years of life gained are being spent with disability and illness, or in good health. Furthermore, it is unclear if all groups in society experience their extra years of life in the same way. This report examines patterns of health expectancies across the island of Ireland, examining any North-South and socio-economic differences as well looking at differences in data sources. The older population (aged 65 or over) on the island of Ireland is growing and becoming a larger percentage of the total  population. Republic of Ireland Census 2011 revealed that 12% of the RoI population was aged 65 or over (CSO, 2012), and Northern Ireland Census 2011 revealed that 13% of the NI population was aged 65 or over (NISRA, 2012). By 2041 the population aged 65 or over is projected to reach 22% in RoI and 24% in NI (McGill, 2010). It is unclear, however, if this increasing longevity will be enjoyed equally by all strata of society.

Experimental toxoplasmosis in Balb/c mice. Prevention of vertical disease transmission by treatment and reproductive failure in chronic infection

In a study of congenital transmission during acute infection of Toxoplasma gondii, 23 pregnant Balb/c mice were inoculated orally with two cysts each of the P strain. Eight mice were inoculated 6-11 days after becoming pregnant (Group 1). Eight mice inoculated on the 10th-15th day of pregnancy (Group 2) were treated with 100 mg/kg/day of minocycline 48 h after inoculation. Seven mice inoculated on the 10th-15th day of pregnancy were not treated and served as a control (Group 3). Congenital transmission was evaluated through direct examination of the brains of the pups or by bioassay and serologic tests. Congenital transmission was observed in 20 (60.6%) of the 33 pups of Group 1, in one (3.6%) of the 28 pups of Group 2, and in 13 (54.2%) of the 24 pups of Group 3. Forty-nine Balb/c mice were examined in the study of congenital transmission of T. gondii during chronic infection. The females showed reproductive problems during this phase of infection. It was observed accentuated hypertrophy of the endometrium and myometrium. Only two of the females gave birth. Our results demonstrate that Balb/c mice with acute toxoplasmosis can be used as a model for studies of congenital T. gondii infection. Our observations indicate the potential of this model for testing new chemotherapeutic agents against congenital toxoplasmosis.
