Doñana National Park (DNP) in southern Spain is a UNESCO Biosphere Reserve where commercial hunting and wildlife artificial feeding do not take place and traditional cattle husbandry still exists. Herein, we hypothesized that Mycobacterium bovis infection prevalence in wild ungulates will depend on host ecology and that variation in prevalence will reflect variation in the interaction between hosts and environmental risk factors. Cattle bTB reactor rates increased in DNP despite compulsory testing and culling of infected animals. In this study, 124 European wild boar, 95 red deer, and 97 fallow deer were sampled from April 2006 to April 2007 and analyzed for M. bovis infection. Modelling and GIS were used to identify risk factors and intra and inter-species relationships. Infection with M. bovis was confirmed in 65 (52.4%) wild boar, 26 (27.4%) red deer and 18 (18.5%) fallow deer. In the absence of cattle, wild boar M. bovis prevalence reached 92.3% in the northern third of DNP. Wild boar showed more than twice prevalence than that in deer (p<0.001). Modelling revealed that M. bovis prevalence decreased from North to South in wild boar (p<0.001) and red deer (p<0.01), whereas no spatial pattern was evidenced for fallow deer. Infection risk in wild boar was dependent on wild boar M. bovis prevalence in the buffer area containing interacting individuals (p<0.01). The prevalence recorded in this study is among the highest reported in wildlife. Remarkably, this high prevalence occurs in the absence of wildlife artificial feeding, suggesting that a feeding ban alone would have a limited effect on wildlife M. bovis prevalence. In DNP, M. bovis transmission may occur predominantly at the intra-species level due to ecological, behavioural and epidemiological factors. The results of this study allow inferring conclusions on epidemiological bTB risk factors in Mediterranean habitats that are not managed for hunting purposes. Our results support the need to consider wildlife species for the control of bTB in cattle and strongly suggest that bTB may affect animal welfare and conservation.

Nutritional support in acute renal failure must take into account the patient's catabolism and the treatment of the renal failure. Hypermetabolic failure is common in these patients, requiring continuous renal replacement therapy or daily hemodialysis. In patients with normal catabolism (urea nitrogen below 10 g/day) and preserved diuresis, conservative treatment can be attempted. In these patients, relatively hypoproteic nutritional support is essential, using proteins with high biological value and limiting fluid and electrolyte intake according to the patient's individual requirements. Micronutrient intake should be adjusted, the only buffering agent used being bicarbonate. Limitations on fluid, electrolyte and nitrogen intake no longer apply when extrarenal clearance techniques are used but intake of these substances should be modified according to the type of clearance. Depending on their hemofiltration flow, continuous renal replacement systems require high daily nitrogen intake, which can sometimes reach 2.5 g protein/kg. The amount of volume replacement can induce energy overload and therefore the use of glucose-free replacement fluids and glucose-free dialysis or a glucose concentration of 1 g/L, with bicarbonate as a buffer, is recommended. Monitoring of electrolyte levels (especially those of phosphorus, potassium and magnesium) and of micronutrients is essential and administration of these substances should be individually-tailored.

BACKGROUND Adipose tissue is a key regulator of energy balance playing an active role in lipid storage and may be a dynamic buffer to control fatty acid flux. Just like PPARgamma, fatty acid synthesis enzymes such as FASN have been implicated in almost all aspects of human metabolic alterations such as obesity, insulin resistance or dyslipemia. The aim of this work is to investigate how FASN and PPARgamma expression in human adipose tissue is related to carbohydrate metabolism dysfunction and obesity. METHODS The study included eighty-seven patients which were classified according to their BMI and to their glycaemia levels in order to study FASN and PPARgamma gene expression levels, anthropometric and biochemical variables. RESULTS The main result of this work is the close relation between FASN expression level and the factors that lead to hyperglycemic state (increased values of glucose levels, HOMA-IR, HbA1c, BMI and triglycerides). The correlation of the enzyme with these parameters is inversely proportional. On the other hand, PPARgamma is not related to carbohydrate metabolism. CONCLUSIONS We can demonstrate that FASN expression is a good candidate to study the pathophysiology of type II diabetes and obesity in humans.

The Andalusian Public Health System (SSPA) is considering the last time an attempt urgent process management through triage consultation, both hospital and primary care environment and tables situations in which the nurse responsible for these consultations can carry out a final statement of which only she is directly responsible through their independent intervention and referral (Triage Advanced). Pose, at once and consistently to the idea of teamwork, where they can be the limits to that intervention finalist and the circuits to follow. This paper proposes a definition line of one of those situations through triage concepts universally tested, and takes full advantage of advanced practice profile offered by nurses Device Critical Care (DCCU) of the SSPA and any the emerging legal and regulatory framework in terms of standardized collaborative prescription, us know legitimate receivers. This work stems from the vision of professionals and our contribution to that line of institutional work that must be consensus.

Objective: To asses the results of Autologous Chondrocyte Implantation (ACI) whith periosteal patch and To propagate the care circuits existing about in Andalusia. Material and Methods: From its of ficial licence in 2005, the tissue bank and the Virgen de la Victoria Hospital from Málaga, performed the ACI in the Andalusian public health system. 16 patients has been operated between 2006-2013, whith medium follow-up 47,6 months (6 months-6 years), from public hos- pitals throughout Andalucia, managed by hospital admission source and destination. Physiologically younger patients were selected (<50 años), with singles, > 2cm2 symptomatics chondral lesions, in stables and well aligned knees. ACI was used as res- cue procedure after microfracture ́s failure except osteochondritis dissecans. To assess the results the Concinnati score and the Short Form 36 (SF-36) score were used. A descriptive analysis was performed and non-parametric tests were used to establish correlations and compare results. Results: In 15 patients with more than one year of follow-up: 14 men(87.5%) and 2women (14.5%), medium age 28.2 years old (min 17 max 43), the lesion was located into de femoral condyle, mostly in the internal one (81,2%) with medium size 2,7cm2(2-4,2). We founded significant improvement (p<0,001), both daily activities ( 89,3% preop. limitatión - 9% postop), as in the sports (90,2% preop limitatión - 38% postop) and the exploration of the knee (67,7% hpatological findings preop- 13,3%postop). The SF-36 score improved in all categories, over all in mental health (p> 0,01). The patient satisfaction was high or very high in 12 of the 15 patients ( 80%), and low in 3 patients. Conclusions: ACI improve quality of life and knee function in femoral condyle chondral lesions. The case ́s selection and the collaboration with Tissue Bank, allows us to create care circuits for treatment of patients from other provinces in the Public Sanitary Health System in Andalucia. It is necessary to increase the experience with this type of therapy, consolidating multicenter workgroups that provide strength to the conclusions.

The impact of the social support and the psychic morbidity on the quality of life of patients with antiretroviral therapy. The aim of this study is to analyse the existing relation between the psychic morbidity and social support and the quality of life. Besides this, the paper analyses the buffer rol that social support plays on the psychic morbidity in these patients. We studied 320 HIV+ patients in truatment with antiretrovirals, who attended the infectious disease services of four hospitals of the Autonomous Andalusian Community. Being associated a better quality of life to an absence of psychic morbidity and to the presence of social support, it is observed the relevant buffer role that the social support like shock absorber of the psychic morbidity in this one type of patients. These results show the importance that the psycho-social factors have during the course of chronic diseases.

A methotrexate-containing medium for the detection of beta-hemolytic group B streptococci from clinical specimens on the basis of detection of pigment is described. The medium contained peptone, starch, serum, MgSO4, glucose, pyruvate, methotrexate (as pigment enhancer), phosphate-morpholine-propanesulfonic acid buffer, and selective agents. The recovery of beta-hemolytic group B streptococci was comparable to that obtained with selective broth.
