Sediment disturbance patterns in the coastal area off the Tagus Estuary (Portugal) have been assessed using a set of combined techniques. The potential sources of disturbance in the area include ...chronic contamination of the fine sediments originating from the estuary, a local input from a long-sea sewage outfall and occasional high runoff episodes following torrential rain. The Sediment Quality Triad approach, combining environmental chemistry (namely organic contaminants), macrofaunal benthic communities and laboratory sediment toxicity assays, was performed on sediment samples from 20 sites. The samples were collected before the outfall commenced operation and four years after commissioning, in order to evaluate the relative magnitudes of the three potential sources of disturbance. The sediment contamination created by the estuary was identified as the most important cause of reduced sediment quality, as disturbance in all three components of the Sediment Quality Triad were only found in a site located near the estuary.

Conceptual approach to the world of the valuesIntending to clarify the conception of values in the knowledge society, some controversial subjects about values are analyzed: the most relevant axiological principles, the motivations for the values in an educational context, conceptualization and genesis of values in the human being.

Guia marine outfall is the largest sewage discharge system in Portuguese waters. It serves four municipalities and a population of approximately 600,000 inhabitants. Effluent diffusion occurs ...approximately 3 Km from the shore, at a depth of 40 meters. Operation of the outfall was initiated in May/June 1994 and, at present, does not include secondary treatment, or conventional primary treatment. In March 1994, before operation of the outfall, an integrated monitoring program was designed, which included a baseline sediment survey. Environmental chemistry, macrofaunal benthic communities and laboratory sediment toxicity analyses were performed in sediments from 20 sampling sites. These sites were revisited 3 and 4.5 years later in order to evaluate any changes to the sediments and their associated biota. This paper presents the results obtained from those two sampling periods, and proposes a classification for the evolution of sediment status. It also addresses the need or not to introduce, at present, more elaborate effluent treatment methods.

As part of the monitoring program from Instituto Hidrográfico, since 1981 sediment and water samples have been collected from four different estuarine areas located along the continental coast of ...Portugal. The concentrations of different parameters were measured in the water and sediment samples. After normalization, the concentrations of chromium, mercury, lead and zinc in the sediments from the different areas were compared.
BACKGROUND:In this study, our objective was to determine whether a perioperative hemodynamic protocol based on noninvasive cardiac output monitoring decreases the incidence of postoperative ...complications and hospital length of stay in major abdominal surgery patients requiring intensive care unit admission. Secondary objectives were the time to peristalsis recovery and the incidence of wound infection, anastomotic leaks, and mortality.
METHODS:A randomized clinical trial was conducted in 6 tertiary hospitals. One hundred forty-two adult patients scheduled for open colorectal surgery, gastrectomy, or small bowel resection were enrolled. A hemodynamic protocol including fluid administration and vasoactive drugs based on arterial blood pressure, cardiac index, and stroke volume response was compared with standard practice. Patients were followed until hospital discharge (determined by a surgeon blinded to the study) or death. In contrast to previous studies, we designed a pragmatic trial (as opposed to explanatory trials) to mimic real practice and obtain maximal external validity for the study.
RESULTS:Fluid administration was similar except for the number of colloid boluses (2.4 ± 1.8 treated vs 1.3 ± 1.4 control; P < 0.001) and packed red blood cell units (0.6 ± 1.3 treated vs 0.2 ± 0.6 control; P = 0.019). Dobutamine was used in 25% (intraoperatively) and 19.4% (postoperatively) of the treated patients versus 1.4% and 0% in the control group (P < 0.001). We have observed a reduction in reoperations in the treated group (5.6% vs 15.7%; P = 0.049). However, no significant differences were observed in overall complications (40% vs 41%; relative risk 0.99 0.67–1.44; P = 0.397), length of stay (11.5 8–15 vs 10.5 8–16; P = 0.874), time to first flatus (62 hours 40–76 vs 72 hours 48–96; P = 0.180), wound infection (7 vs 14; P = 0.085), anastomotic leaks (2 vs 5; P = 0.23), or mortality (4.2% vs 5.7%; P = 0.67).
CONCLUSIONS:The results of our pragmatic study indicate that a perioperative hemodynamic protocol guided by a noninvasive cardiac output monitor was not associated with a decrease in the incidence of overall complications or length of stay in major abdominal surgery.
Abstract Background and Aims Recent evidence observed changes in saliva composition and an oral dysbiosis in end-stage renal disease (ESRD) patients. Despite of that, the relationship between oral ...microbiome and oral peptidome in kidney transplant recipients (KTR) is still unexplored. Therefore, the aim of this study is to investigate the interplay between oral microbiome and oral peptidome in KTR from live kidney donors (LKD) and to analyze their relevance on the recovery of renal function. Method This prospective study enrolled 11 adult KTR/LKD pairs to whom saliva was collected before organ transplant/donation (T0) and at 6 (T6), 12 (T12), and 24 (T24) months after (dropout rate up to 45% at T24). Saliva microbiome was evaluated by throughput sequencing (16SrRNA gene) and low-molecular weight salivary proteome by LC-MS/MS analysis. Results The glomerular filtration rate (GFR) of KTR recover to normal levels after transplant. Oral microbiome of ESRD differ significantly from healthy donors (T0; p = 0.04), however these differences fade away progressively post-transplant, presenting only a slight difference at T6 (p = 0.046) but no differences at T12 and T24. Also, 21 proteins were found dysregulated in ESRD and after protein-protein interaction analysis were organized into two functional clusters: one mainly composed by cysteine protease inhibitors, and another mainly composed by metabolism-related enzymes (lactate dehydrogenase, catalase, and arginase-1). Almost all differences between LKD and KTR became elusive at 6 months. It was found an inverse correlation between Streptococcus and peptidyl-prolyl-cis-trans-isomerase-A, a protein with a strong chemotactic effect on leukocytes, and a positive correlation between Bergeyellaand cystatin-D (CST5), a cysteine proteases-protective protein. The remaining secreted cystatins (CST1/2/4), but not CST5 were found significantly correlated with GFR, suggesting that renal function recovery is paralleled related to an increase in oral cystatins. Also, an inverse relationship between Bergeyella and GFR suggests that the renal function recovery has implications in the composition of oral microbiota. Conclusion This study may provide relevant clues about the oral cavity-kidney axis dynamics and pinpoint potential markers of renal function impairment and/or recovery in KTR.
