Behaviour of pre-parturient sows housed in intensive outdoor or indoor systems

This work compared the behaviour of pre-parturient sows housed in intensive confined and outdoor systems, during the morning and afternoon prior to delivery. Eight sows were kept individually in farrowing crates or in paddocks with access to fresh pasture from 8 to 10 days before expected parturition. All outdoor sows built a nest within 24 hours before farrowing. On the morning and afternoon before farrowing they spent 6.5% of the time collecting grass and 7.5% of the time organizing the nest. Outdoor sows were observed more often than confined sows rooting (4.60% vs. 0.25%), feeding (10.2% vs. 3.0%), standing (51% vs. 13%) and walking (8% vs. 0%). Indoor sows redirected the nesting behaviour to other behaviours like attempts to dig the ground, nosing, biting and rooting parts of the crate, feeder or drinker, during 4.7% of the time. They also spent more time than outdoor sows inactive (85% vs. 60%), lying (72% vs. 41%), drinking (2.1% vs. 0.5%) and vacuum chewing (3.7% vs. 0.1%). The pre-parturient behaviour of sows was considerably affected by the husbandry system. The outdoor system appears to be more appropriate for the sows' welfare than the conventional confinement.

Preserving the health of ambulance personnel : some preliminary results from a study of pre-hospital emergency interventions

Little is known about the health of ambulance personnel, especially in Switzerland. This lack of knowledge is particularly striking in the specific field of occupational health. This study aims to identify and better understand protective and risk factors affecting the health of ambulance personnel. Both mental and physical health are considered. The approach used comprised two steps. The first step began in July 2008 and consisted in a qualitative study of real work activities performed by ambulance crews involved in pre-hospital emergency interventions. Researchers shadowed ambulance personnel for the duration of their entire work shift, in average for one week. The paper-pen technique was used to note dialogues, interactions, postural aspects, etc. When the situation allowed it, interventions were filmed. Some selected video sequences were used as a support for selfconfrontation interviews. Observations were performed by three researchers and took place in eleven services, for a total of 416 hours of observations (including 72 interventions + waiting time). Analysis, conducted by a multidisciplinary team (an ergonomist, an occupational therapist and a health psychologist), focused on individual and collective strategies used by ambulance personnel to protect their health. The second step, which is currently ongoing, aims to assess global health of ambulance personnel. A questionnaire is used to gather information about musculoskeletal complaints (Nordic questionnaire), mental health (GHQ-12), stress (Effort-Reward imbalance questionnaire), strategies implemented to cope with stress (Brief COPE), and working conditions. Specific items on strategies were developed based on observational data. It will be sent to all ambulance personnel employed in the French-speaking part of Switzerland. Preliminary analyses show different types of strategies used by ambulance personnel to preserve their health. These strategies involve postural aspects (e.g. use doorframe as a support to ease delicate manipulations), work environment adaptations (e.g. move furniture to avoid awkward postures), coping strategies (e.g. humor), as well as organisational (e.g. formal and informal debriefing) and collective (e.g. cooperation) mechanisms. In-depth analysis is still ongoing. However, patient safety and comfort, work environment and available resources appear to influence the choice of strategies ambulance personnel use. As far as possible, the strategies identified will be transformed into educational materials for professional ambulance personnel.

pre/parats?

Aquestes pàgines contenen la feina de nou mesos que va resultar en un documental que investiga la realitat dels joves universitaris dins del marc socioeconòmic actual. Pre/parats? és el títol que dóna nom a aquest documental. La nostra intenció era jugar amb el doble sentit de les paraules per a referir-nos a la situació postuniversitària. Així doncs, plantegem si estem preparats per afrontar el món laboral o si, per contra, som els pròxims a la cua de l’atur. El treball està dividit en funció de les fases que es duen a terme a l’hora de realitzar una peça audiovisual: començant per la primera fase, la presa de decisions; passant també per la resta de fases, com són el desenvolupament del guió, la preproducció, el rodatge, el muntatge i la postproducció; i acabant per la distribució del producte. Per últim, hi ha les conclusions finals de cada un dels membres del grup i les conclusions generals del projecte.

Cooperating pre-T-cell receptor and TCF-1-dependent signals ensure thymocyte survival.

Intrathymic T-cell maturation critically depends on the selective expansion of thymocytes expressing a functionally rearranged T-cell receptor (TCR) beta chain. In addition, TCR-independent signals also contribute to normal T-cell development. It is unclear whether and how signals from the 2 types of pathways are integrated. Here, we show that T-cell factor-1 (TCF-1), a nuclear effector of the canonical wingless/int (wnt)/catenin signaling pathway, ensures the survival of proliferating, pre-TCR(+) thymocytes. The survival of pre-TCR(+) thymocytes requires the presence of the N-terminal catenin-binding domain in TCF-1. This domain can bind the transcriptional coactivator beta-catenin and may also bind gamma-catenin (plakoglobin). However, in the absence of gamma-catenin, T-cell development is normal, supporting a role for beta-catenin. Signaling competent beta-catenin is present prior to and thus arises independently from pre-TCR signaling and does not substantially increase on pre-TCR signaling. In contrast, pre-TCR signaling significantly induces TCF-1 expression. This coincides with the activation of a wnt/catenin/TCF reporter transgene in vivo. Collectively, these data suggest that efficient TCF-dependent transcription requires that pre-TCR signaling induces TCF-1 expression, whereas wnt signals may provide the coactivator such as beta-catenin. The 2 pathways thus have to cooperate to ensure thymocyte survival at the pre-TCR stage.

Automatic Recognition of Leaves by Shape Detection Pre-Processing with Ica

In this work we present a simulation of a recognition process with perimeter characterization of a simple plant leaves as a unique discriminating parameter. Data coding allowing for independence of leaves size and orientation may penalize performance recognition for some varieties. Border description sequences are then used to characterize the leaves. Independent Component Analysis (ICA) is then applied in order to study which is the best number of components to be considered for the classification task, implemented by means of an Artificial Neural Network (ANN). Obtained results with ICA as a pre-processing tool are satisfactory, and compared with some references our system improves the recognition success up to 80.8% depending on the number of considered independent components.

Increased salt sensitivity of ambulatory blood pressure in women with a history of severe preeclampsia.

Cardiovascular diseases are the principal cause of death in women in developed countries and are importantly promoted by hypertension. The salt sensitivity of blood pressure (BP) is considered as an important cardiovascular risk factor at any BP level. Preeclampsia is a hypertensive disorder of pregnancy that arises as a risk factor for cardiovascular diseases. This study measured the salt sensitivity of BP in women with a severe preeclampsia compared with women with no pregnancy hypertensive complications. Forty premenopausal women were recruited 10 years after delivery in a case-control study. Salt sensitivity was defined as an increase of >4 mm Hg in 24-hour ambulatory BP on a high-sodium diet. The ambulatory BP response to salt was significantly increased in women with a history of preeclampsia compared with that of controls. The mean (95% confidence interval) daytime systolic/diastolic BP increased significantly from 115 (109-118)/79 (76-82) mm Hg on low-salt diet to 123 (116-130)/80 (76-84) on a high-salt diet in women with preeclampsia, but not in the control group (from 111 [104-119]/77 [72-82] to 111 [106-116]/75 [72-79], respectively, P<0.05). The sodium sensitivity index (SSI=Δmean arterial pressure/Δurinary Na excretion×1000) was 51.2 (19.1-66.2) in women with preeclampsia and 6.6 (5.8-18.1) mm Hg/mol per day in controls (P=0.015). The nocturnal dip was blunted on a high-salt diet in women with preeclampsia. Our study shows that women who have developed preeclampsia are salt sensitive before their menopause, a finding that may contribute to their increased cardiovascular risk. Women with a history of severe preeclampsia should be targeted at an early stage for preventive measures of cardiovascular diseases.

Réduction de la consommation de sel: une mesure importante de santé publique en Suisse. [Reducing dietary salt intake: an important public health strategy in Switzerland]

La consommation actuelle de sel (chlorure de sodium) est très supérieure aux besoins physiologiques (1,5 g par jour, soit environ 550 mg par jour de sodium) dans la plupart des pays (> 8 g par jour). Les principales sources de sel sont les pains, les fromages, les produits dérivés de la viande et les plats précuisinés. En moyenne, une consommation élevée de sel est associée à une pression artérielle plus élevée. En Suisse, un adulte sur trois souffre d'hypertension artérielle. La moitié des accidents vasculaires cérébraux et des maladies cardiaques ischémiques sont attribuables à une pression artérielle trop élevée. L'Office fédéral de la santé publique conduit actuellement une stratégie visant à diminuer la consommation de sel dans la population suisse à moins de 5 g par jour sur le long terme (Salz Strategie 2008-2012). [Abstract] Current dietary salt (sodium chloride) intake largely exceeds physiological needs (about 1.5 g salt per day, or 550 mg sodium per day) in most countries (> 8 g salt per day). The main sources of dietar salt intake are breads, cheeses, products derived from meat and ready-to-eat meals. On average, a high-salt diet is associated with higher blood pressure levels. In Switzerland, one out of three adults suffers from arterial hypertension. Half of cerebrovascular events and ischaemic cardiac events are attributable to elevated blood pressure. The Swiss Federal Office of Public Health is currently running a strategy aiming at reducing dietary salt intake in the Swiss population to less than 5 g per day on the long run (Salz Strategie 2008-2012).
