RESUMO

Motivational interviewing (MI)-based interventions can be effective for people living with HIV (PLWHIV) with medical follow-up problems. This study aimed to assess the stage of motivation to attend medical appointments of PLWHIV with medical follow-up problems and to evaluate a single telephone session MI intervention directed to engage them in care. The change in stage was evaluated before and after the intervention, and attending medical appointments was monitored for six months. Thirty-nine PLWHIV participated; 51.3% were in precontemplation/contemplation and 49.7% in preparation/action stage. Most (excluding those in the action stage from the beginning) (n = 22, 71.0%) advanced to another stage after the intervention (z = - 4.235, p < .001), and most did not miss the following appointments. Brief and remote MI interventions could be useful in low-resource settings, especially for those in the early stages of change, to explore motivations related with missing medical appointments.

RESUMO

Although the pour plate method is widely employed in microbiological quality control, it has certain drawbacks, including having to melt the culture medium before seeding. In this study, the preparation of the culture medium was modified by using a lower concentration of agar (10 g/L), which was separated from the nutrients during sterilization. The new protocol was assessed in media frequently used in microbiological quality control of food, cosmetics, and pharmaceutical products, with tryptic soy agar (TSA), Sabouraud 4% dextrose agar (SDA), and violet red bile glucose agar (VRBG). In comparison with the conventionally produced media, the modifications significantly improved the growth of Saccharomyces cerevisiae in SDA, Staphylococcus aureus, Salmonella enterica subsp. enterica serovar Typhimurium, and Candida albicans in TSA and Escherichia coli ATCC 8739 and ATCC 25922 and S. Typhimurium in VRBG. The modified VRBG was also more selective for Pseudomonas aeruginosa. Regarding physicochemical properties, a significantly lower pH was observed in TSA and VRBG and lower strength values in TSA. Sterilizing agar separately from the other components of the medium and reducing the agar concentration to 10 g/L can improve microorganism growth and enhance the selectivity of differential media in the pour plate method. These modifications could facilitate the automation of this culture technique. IMPORTANCE In the era of rapid microbiological methods, there is a need to improve long-established culture techniques. Drawbacks of the pour plate method include having to melt each medium separately before seeding. For this technique, we demonstrate that separating the agar from the other components of commonly used media during sterilization and reducing the agar concentration to 10 g/L can enhance microbial growth. The new protocol could have advantages in routine laboratory practice because less agar is required and the same molten agar suspension can be used to prepare different media. Moreover, these modifications could facilitate the automation of the pour plate method.

RESUMO

Trace elements are pollutants of both natural and anthropogenic origin which can influence negatively on ecosystem and wildlife health. We evaluated trace element in blood samples of gray seal (Halichoerus grypus) stranded in the Gulf of Riga and their influence on their health status through hematological and biochemical profiles. Zn showed the highest levels followed by Cu > Se > Pb > THg > As. Cr and Cd were not detected. Most trace element levels were generally comparable to those reported in seal species; however, high Pb values were observed in those sample showing detectable concentrations (<0.046-257.6 µg/kg ww). Significant positive correlations were found between trace elements concentrations and various biochemical parameters, including Se-ASAT, Se:Hg-ASAT, Cu-TP, Cu-ALB, CuCa, Zn-ALAT, ZN-LDH, ZnP, Zn-Segment neutrophils, and Pb-CK. Nevertheless, most relationships were not strong enough (p > 0.04) to assume a toxicological implication. Despite its limitations, this information could serve as the baseline for future research.

RESUMO

The detection of Salmonella in food is based on the use of a selective enrichment broth such as Muller-Kauffman Tetrathionate-Novobiocin (MKTTn), in which tetrathionate plays a key role by providing Salmonella with a growth advantage. As sodium tetrathionate is unstable, it is generated in situ by the addition of iodine (Lugol's solution) before seeding. This step is cumbersome as the solution is easily spilled, compromising the performance of the medium and hindering the work of technicians. The aim of this study was to optimize MKTTn broth by generating tetrathionate ex situ through an external reaction between iodine and thiosulphate followed by lyophilization. Quality control procedures were performed to compare the modified and original media, testing pure productivity (enrichment with 50-120 CFU of Salmonella Thyphimurium ATCC 14028 and Salmonella Enteritidis ATCC 13076 and plating on Xylose Lysine Deoxycholate agar, XLD), mixed productivity (50-120 CFU of Salmonella strains and Pseudomonas aeruginosa and Escherichia coli at ≥104 CFU and XLD plating) and selectivity (≥104 CFU of P. aeruginosa and Enterococcus faecalis and plating on Tryptone Casein Soy agar, TSA). The modified MKTTn medium (S/L) performed comparably with the original medium in terms of growth of both Salmonella strains (>300 colonies in XLD), alone or with P. aeruginosa and E. coli. Quantitative assays showed no statistically significant differences in the number of colonies grown on XLD after 10-5 dilution (p = 0.7015 with S. Thyphimurium ATCC 14028 and p = 0.2387 with S. Enteritidis ATCC 13076; ANOVA test). MKTTn medium (S/L) was also selective against E. coli (≤100 colonies) and E. faecalis (<10 colonies). These results suggest that adding tetrathionate as a lyophilisate (S/L) is a feasible alternative to the use of Lugol's solution for the preparation of MKTTn enrichment broth and does not affect the properties of the medium.

RESUMO

Homemade herbal preparations from the East of Spain are the witness of traditional medicine inherited from the ancient complex formulas of herbal teas and medicinal wines. In this study, we document the use of traditional alcoholic beverages, identify their ingredients, almost exclusively botanical, record the local medicinal uses of these mixtures, and discuss patterns of distribution of this knowledge in regions of eastern Spain, the Balearic Islands and Andorra. We determine marker species and relevant patterns of herbal formulas in the different regions of the territory. Homemade liquors and liqueurs are consumed for their digestive and tonic-restorative properties but they also play in some cases an important social role. The elderly remember other medicinal uses such as aperitif, emmenagogue, or antidiarrheal, for some of the most popular preparations. The herbal liqueur formulas include predominantly Lamiaceae, Asteraceae, Rosaceae, Rutaceae, and Apiaceae species. Herbs (58%), fruits (28%), and mixtures of both (12%) are ingredients of liquors and wines, being the aerial parts the most frequent in terms of species (30%) and records (49%). Dictamnus hispanicus, Santolina villosa, Salvia blancoana subsp. mariolensis, Rosmarinus officinalis, Thymus vulgaris, and Clinopodium serpyllifolium subsp. fruticosum are the species most frequently used. Others species used to a lesser extent as Polygonatum odoratum, Thymus moroderi, and Saxifraga longifolia are restricted to locally homemade preparations because their collection and uses require special knowledge of the rare or endemic flora. Sustainability of these practices is strongly limited by the overall loss of local traditional knowledge and by the limited availability of most of the wild species; some of them are endangered or threatened mainly by the loss of their natural habitats. Cultivation and domestication are a promising alternative to collecting from wild populations. The cultivation of Thymus moroderi in the province of Alicante and Polygonatum odoratum in the province of Teruel are good examples. There is a notable decrease in the complexity of the formulas registered throughout the nearly 15 years of the study. This is interpreted as a consequence of a loss of knowledge, less accessibility to wild resources, and changes in traditions and preferences.

RESUMO

BACKGROUND: The clinical effect of peri-operative bridging therapy in atrial fibrillation (AF) patients remains unclear given that it may increase bleeding risk without providing significant benefits. We aimed to investigate peri-procedural events in relation to peri-operative use of bridging therapy in AF patients under Vitamin K Antagonists (VKAs). METHODS: We included AF patients stable the previous 6 months on VKAs. During a median follow-up of 6.5 years (IQR 4.3-7.9), we recorded all invasive procedures and the peri-operative clinical management. All peri-procedural events (ischaemic stroke/transient ischaemic attack/systemic embolism, clinically relevant non-major bleeding and major bleeding) and severe peri-procedural events (ischaemic stroke/transient ischaemic attack/systemic embolism and major bleeding) suffered until the 30-days post-intervention period were recorded. RESULTS: We included 1361 patients (48.7% male, median age 76 [IQR 71-81] years). There were 1100 (70.9%) procedures performed using bridging therapy. The rate of any (4.5% vs. 0.7%, P < 0.001) and severe (2.3% vs. 0.0%, P = 0.002) peri-procedural events were higher in patients receiving bridging therapy. Adjusted logistic regressions demonstrated that the bleeding risk of the procedure was related with higher risk of severe peri-procedural events (OR 3.51, 95% CI 1.54-8.01) and peri-procedural events (OR 2.77, 95% CI 1.56-4.91). Importantly, the use of bridging therapy was also independently associated with higher risk of any peri-procedural events (OR 4.32, 95% CI 1.28-14.51). CONCLUSIONS: In this study including AF patients under VKA therapy, the use of bridging therapy as part of the clinical management during an invasive procedure was independently associated with higher risk of any peri-procedural event.

RESUMO

Endocrinology step of transgender readjustment therapy is made according to previously published in the part 1 of article: “gender identity disorder in rev. chil. endocrinol. diabetes 2015, 8 (4): 167-173.During started puberty in Tanner stage 2-3, the persistence of the experience that their identity male or female gender is not coherent with its bodily, authorize to start the endocrinological therapy, as an important step of body readjusting. In the process of transition from male to female or female to male, should stop pubertal development, what we do with GNRH analogues: intramuscle leuprolideor triptorelin 11.25 mg. every 12 weeks or with medroxyprogesterone acetate 150 mg. monthly. This process continues until 16 years, adding antiandrogen, preferably spironolactone in the process of body readjusting of male to female. At 16 years old, starts the cross hormonal therapy to masculinizing or feminizing. Maintaining gonadotrophin suppression, female to male, testosterone undecanoate or other injectable testosterone esters is administered, customizing the date of administration and inMale to female, daily use of oral estradiol valerate or transdermal gel. Plasma levels of estradiol andtestosterone should not be located in high or supraphysiological range to avoid thromboembolism or polycythemia risk in those who receive testosterone. Should to be explained the time to obtain the bodily effects, achieving a realistic attitude of the goals and the need for regular checks. Attendance to emotional changes, mainly to meet the social gender role. The laboratory, metabolic, hormonal, hemogram and electrolytic changes are evaluated.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE AND BACKGROUND: "Dictamnus" was a popular name for a group of medicinal herbaceous plant species of the Rutaceae and Lamiaceae, which since the 4th century have been used for gynaecological problems and other illnesses BCE and still appear in numerous ethnobotanical records. AIMS: This research has as four overarching aims: Determining the historical evolution of medical preparations labelled "Dictamnus" and the different factors affecting this long-standing herbal tradition. Deciphering and differentiating those medicinal uses of "Dictamnus" which strictly correspond to Dictamnus (Rutaceae), from those of Origanum dictamnus and other Lamiaceae species. Quantitatively assessing the dependence from herbal books, and pharmaceutical tradition, of modern Dictamnus ethnobotanical records. Determining whether differences between Western and Eastern Europe exist with regards to the Dictamnus albus uses in ethnopharmacology and ethnomedicine. METHODS: An exhaustive review of herbals, classical pharmacopoeias, ethnobotanical and ethnopharmacological literature was conducted. Systematic analysis of uses reported which were standardized according to International Classification of Diseases - 10 and multivariate analysis using factorial, hierarchical and neighbour joining methods was undertaken. RESULTS AND DISCUSSION: The popular concept "Dictamnus" includes Origanum dictamnus L., Ballota pseudodictamnus (L.) Benth. and B. acetabulosa (L.) Benth. (Lamiaceae), as well as Dictamnus albus L. and D. hispanicus Webb ex Willk. (Rutaceae), with 86 different types of uses. Between 1000 and 1700 CE numerous complex preparations with "Dictamnus" were used in the treatment of 35 different pathologies. On biogeographical grounds the widespread D. albus is a far more likely prototypical "Dictamnus" than the Cretan endemic Origanum dictamnus. However both form integral parts of the "Dictamnus" complex. Evidence exists for a sufficiently long and coherent tradition for D. albus and D. hispanicus, use to treat 47 different categories of diseases. CONCLUSIONS: This approach is a model for understanding the cultural history of plants and their role as resources for health care. "Dictamnus" shows how transmission of traditional knowledge about materia medica, over 26 centuries, represents remarkable levels of development and innovation. All this lead us to call attention to D. albus and D. hispanicus which are highly promising as potential herbal drug leads. The next steps of research should be to systematically analyse phytochemical, pharmacological and clinical evidence and to develop safety, pharmacology and toxicology profiles of the traditional preparations.

RESUMO

A 53 m(3) microalgae pilot plant with semi-closed photobioreactors has been operated in batch mode at Tarragona, where proper climatic conditions exist. Operations carried-out were microalgae culturing, concentration, cell disruption and lipid extraction. Culturing was performed with and without CO2 fertilization. pH was used to control CO2 dosing. With CO2 fertilization best microalgae concentrations were obtained. Productivities up to 19.9 g/m(2)/day were reached. Although sedimentation and centrifugation was performed, studies focused on dynamic membrane filtration as improved technique compared with conventional one. Significant fouling reduction was obtained by using a vibrational membrane setup. Cell disruption including product pre-extraction was performed by using steam explosion at moderate conditions, as novel technique for this application. Lipid extraction was performed by using conventional techniques with and without exploded material. The amount of lipids obtained from exploded material was higher than with non-exploded material, which shows that steam explosion provides a clear enhancement.

RESUMO

UNLABELLED: Refeeding after acute pancreatitis (AP) is traditionally started in a successively increasing manner when abdominal pain is absent and pancreatic enzymes are decreasing. We aimed to evaluate length of hospital stay (LOHS) and refeeding tolerance for early refeeding and/or immediately full caloric intake in patients recovering from AP. METHODS: In this randomized, open-label trial, patients with AP were randomized into four different refeeding protocols. Group 1 and 2 received a stepwise increasing diet during three days while 3 and 4 received an immediately full caloric, low fat diet. Group 2 and 4 started refeeding early (once bowel sounds returned) and 1 and 3 started at standard time (bowel sounds present, no abdominal pain, no fever, leucocytes and pancreatic enzymes decreasing). Main outcomes measurements were LOHS and tolerance (ability to ingest >50% of meals without severe pain, nausea or AP relapse). RESULTS: Eighty patients were evaluated and 72 randomized (median age 60 years, range 24-85, 33 male). LOHS was significantly reduced after early refeeding (median 5 versus 7 days (p = 0.001)) but not in patients receiving immediately full caloric diet, compared to standard management (6 versus 6 days (p = 0.12)). There was no difference in refeeding tolerance comparing immediately full caloric diet versus stepwise increasing diet (31/35 (89%) versus 33/37 (89%) patients tolerating the treatment, p = 1.00) or early versus standard time for refeeding (33/37 (89%) versus 31/35 (89%), (p = 1.00)). CONCLUSIONS: Refeeding after AP when bowel sounds are present with immediately full caloric diet is safe and well tolerated. Early refeeding shortens LOHS.

RESUMO

An intensity enhancement of the green upconversion emission from a codoped Er(3+)-Yb(3+) fluoroindate glass has been obtained by coating the glass surface with silica microspheres (3.8 µm diameter). The microspheres focus an incoming beam (λ ≈ 950 nm) on the surface of the fluoroindate glass. The green emission (λ ≈ 545 nm) of the Er(3+) ions located in the microsphere focus was measured with a microscope in reflection mode, being the peak intensity 4.5 times the emission of the bare substrate. The transversal FWHM of the upconversion spot was experimentally determined by deconvolution with the experimental Point Spread Function of the system, obtaining a value of 309 nm. This value is in good agreement with Finite-Difference Time-Domain simulations taking into account the magnification of the image due to the microsphere.

RESUMO

Trend in Tuberculosis (TB) rates and association of factors affecting the outcome of this disease were assessed in the Health Service of Viña del Mar-Quillota, Chile from 1999 to 2008. Study of 1291 TB patients by the years 1999 to 2008. We evaluated incidence and mortality rate per 100,000 inhabitants, pulmonary / extrapulmonary ratio, presence of HIV, death and site of infection. It was found a decreasing trend in the incidence rate (p < 0.001 R² = 0.97) and association between the presence of HIV and case fatality rate (p < 0.001). It was not found association between site of disease and mortality rate (p = 0.3) nor a decreasing trend in mortality (p = 0.116) and pulmonary/extrapulmonary ratio (p = 0.194). There is a decreasing trend in the incidence rate of TB patients which reflects a well-functioning system of control and surveillance; the presence of HIV is associated with death because of this it should be considered in clinical management of TB.


Se evalúa la tendencia de las tasas de incidencia de tuberculosis (TBC) y de factores asociados al desenlace de esta enfermedad, en el Servicio de Salud Viña del Mar-Quillota durante los años 1999 2008. Estudio de 1.291 pacientes con TBC entre los años 1999-2008. Se evalúa tasa de incidencia y mortalidad por 100.000 habitantes, razón de casos pulmonares/extrapulmonares, presencia de VIH, tasa de letalidad y localización de la infección. Se observa una tendencia decreciente en la tasa de incidencia (p <0,001; R² = 0,97) y asociación entre presencia de VIH y fallecer (p < 0,001). No se observa asociación entre localización de la enfermedad y fallecimiento (p = 0,3), ni tendencia decreciente en la tasa de mortalidad (p = 0,116) ni en la razón de casos pulmonares/extrapulmonares (p = 0,194). La tendencia decreciente de la tasa de incidencia de TBC refleja un buen funcionamiento del sistema de control y vigilancia. La infección por VIH se asocia con mayor riesgo de muerte por lo que debe considerarse en el enfrentamiento clínico de la TBC.

RESUMO

Carcinoid syndrome is observed in one third of carcinoid tumors and usually appears when there are liver metastases. One of the main complications of this syndrome is the appearance of tricuspid or pulmonary valvular disease. We report a 56 years old male presenting with malaise and a weight loss of 10 kg. On physical examination, a heart murmur suspicious of a double tricuspid lesion was found. The echocardiogram was suggestive of a carcinoid valvular disease. The abdominal CAT scan showed a small bowel tumor. Urinary 5-hydroxy-indol- acetic acid values were highly elevated. The patient was subjected to excision of the distal ileum, liver metastasectomy and hemicolectomy. The pathological study of the surgical piece confirmed the diagnosis of carcinoid tumor. Two years after surgery, the patient is in stable conditions.

RESUMO

Introducción: la Poliarteritis nodosa (PAN) se define como una vasculitis necrotizante que compromete a las arterias de mediano calibre, y causa un compromiso sistémico. Existe una asociación entre la PAN y la infección por el virus de la Hepatitis B, en relación principalmente con el depósito de inmunocomplejos virales circulantes. Las manifestaciones clínicas son inespecíficas y requiere un alto índice de sospecha. Se han usado varios regímenes de inmunosupresores (corticoides-ciclofosfamida) plasmaféresis y drogas antivirales, con respuestas variables. Objetivo: presentación de un caso clínico de PAN asociado con infección por virus de Hepatitis B, y revisión de la literatura. Caso clínico: paciente masculino de 40 años, con manifestaciones severas de Poliartritis nodosa, asociado con infección por Hepatitis B. Conclusiones: la PAN es una enfermedad poco frecuente, la asociación con infección por Hepatitis B está bien documentada y las estrategias terapéuticas difieren de las de la PAN clásica. Es una patología potencialmente fatal cuando no se reconoce y trata adecuadamente


Backgraound: Polyarteritis nodosa (PAN) is defined by a necrotizing vasculitis of medium sized arteries that causes a systemic inflammatory disease. There is an association between PAN and hepatitis B virus (HBV) infections, related mostly with viral circulting immune complexes. Clinical manifestations are not specific and require a high index of suspicion. Several immunosuppressive regimens (corticoids-ciclophosphamide), plasmapheresis and antiviral drugs have been used with varying response. Objective: Report of a clinical case of PAN associated with Hepatitis B virus infection and review of the literature. Case-reporte: A 40 year old man with severe manifestations of Polyarteritis nodosa, associated with Hepatitis B infection. Conclusions: PAN is uncommon disease, the association with hepatitis B virus infection is well documented, and the treatment strategies differs from the classic PAN. It is a potentially fatal disease when unrecognized and untreated

RESUMO

Using a priming paradigm in the context of a reading comprehension task, the possibilities that people keep in mind in order to understand indicative and subjunctive concessive sentences were examined and compared to those from factual and counterfactual 'if A, not-B' conditionals. The length of time it took people to read conjunctive descriptions (i.e., A and B, A and not-B, not-A and B, not-A and not-B) after they had been primed by the different types of linguistic form was measured. The results suggest that, whereas indicative 'even though' concessives and 'if, not' conditionals are understood by keeping in mind just a single possibility ('A and B' and 'A and not-B', respectively), the initial representations of subjunctive 'even if' concessive-conditionals and 'if, not' counterfactuals are compatible with a multiple-model representation. The implications of these results are discussed within the mental models framework.

RESUMO

Tumor induced osteomalacia is uncommon and is characterized by an isolated and not PTH dependent reduction in tubular phosphate reabsorption. This alteration is produced by phosphaturic factors, such as fibroblast growth factor-23 (FGF-23) that are secreted by tumors. We report a 41 years old female presenting with joint pain and progressive loss of muscle strength in the lower limbs. Initial laboratory assessment showed hypophosphatemia, elevated alkaline phosphatases, normal intact parathormone levels, low levels of 25 hydroxy vitamin D and an elevated 24 h phosphaturia. Bone mineral density showed spine and femoral neck osteopenia. A positron emission tomography (PET) revealed a right thigh tumor with lung metastases. Its biopsy disclosed a fibrosarcoma. FGF-23 levels, measured by ELISA were markedly elevated. The patient was discharged with palliative measures.

RESUMO

Gastrointestinal symptoms in patients with SLE are common, specifically abdominal pain. However, the rate of pancreatic diseases is much lower and does not reach 5% according to published series in Europe and the USA. This association between SLE and pancreatic disease is basically at the expense of episodes of acute pancreatitis. An association with chronic pancreatitis is much more uncommon, and only four articles have been published showing this relationship. Three cases of SLE-associated pancreatitis are described, and disease onset, etiological factors, and clinical progression are analyzed. A review of the literature and a brief discussion about pathophysiological mechanisms and the role of corticosteroids are also included.

RESUMO

INTRODUCTION: An increased incidence and magnitude of leukopenia during concomitant treatment with valganciclovir (VGC) and mycophenolate mofetil (MMF) has been reported. OBJECTIVE: To evalute the incidence and severity of leukopenia and neutropenia among liver recipients treated with VGC and related factors. PATIENTS AND METHODS: Retrospective analysis of clinical and analytical data related to leukopenia (<3000 leukocytes/mm(3)) and neutropenia (<900 neutrophils/mm(3)) in liver transplant patients who were treated with VGC from 2003 to 2007. We examined the influence of concomitant administration of MMF and development of subsequent infections. RESULTS: Among 209 liver transplants, 40 treatments with VGC were prescribed in 37 patients (17.7%), 12 of which (30%) were associated with MMF. The patients has an average age of 49.7 +/- 12.7, body mass index (BMI) of 27.28 +/- 5.17, and Model for End-stage Liver Disease Score (MELD) 12.45 +/- 7.5. The daily average dose of VGC was 1440 +/- 446.5 mg and MMF, 1454.5 +/- 350.3 mg. We observed a decrease of 30% in initial leukocyte count (5353.7 +/- 2706.6) and 40% in neutrophil count (3600 +/- 2182.1). With no relationship to total dose or BMI-adjusted dose of VGC nor concomitant administration of MMF. The initial leukocyte count was significantly lower (4411 +/- 1930 vs 6206 +/- 3053; P = .03) and underwent a main drop (2344.7 +/- 1974.3 vs 898.1 +/- 2435.6; P = .04) when leukopenia developed. In the induced neutropenia group, previous leukocyte count (3797.1 +/- 1223.9 vs 5683.9 +/- 2829.3; P = .01), MELD (18.7 +/- 8.8 vs 11.1 +/- 6.6; P = .01), and the creatinine pretreatment (1.44 +/- 0.4 vs 1.09 +/- 0.3; P = .01) were significantly different. Subsequent infections induced by the leukopenia were not observed. CONCLUSIONS: In our series, the concomitant use of VGC and MMF was not associated with a greater incidence of leukopenia and/or neutropenia than VGC administration alone. Previous leukocyte count was associated with them. MELD and renal dysfunction are factors related to severe neutropenia. Leukopenia was not associated with a greater incidence of infections.

RESUMO

The aim of this study was to integrate hydrochemical and sediment data in order to obtain a picture of the pollution state of the Tagus River along central Spain. This area is of special interest because tributaries from the Madrid region are discharged and no previous data were available. Waters and sediments were sampled between 2002 and 2004 from selected sites before and after Jarama River confluence (Madrid city input). The samples were analysed for more than 50 parameters, including those of physico-chemical nature and those reporting the pollution caused by both metals and organic compounds. The quality of waters for different uses has been tested and statistical quality indexes of both global and partial type has also been established. Sediments pollution state was evaluated by comparison with general quality standards. A high degree of pollution and general degradation was observed in the Tagus River downstream the Jarama River input. The pollution of waters is mainly related to parameters indicators of organic pollution from urban sewage. In sediments, a dramatic increase in the concentration of trace metals was found in different points, exceeding toxicological threshold. Further studies would be necessary for organic pollutants and also to evaluate the remobilization potential.
