Abstract
BACKGROUND Therapeutic education programs are effective in several chronic conditions. However, evidence is lacking in multiple system atrophy (MSA). We aimed to assess efficacy and safety of a comprehensive therapeutic education program in people with MSA (PwMSA) and their caregivers. METHODS In this prospective longitudinal study we included 16 PwMSA and their main caregivers in 4 groups of 4 dyads each. The program consisted of eight 60-min interdisciplinary sessions: introduction, orthostatic hypotension, speech therapy, gait and respiratory physiotherapy, psychological support, urinary dysfunction, occupational therapy/social work. UMSARS, NMSS, PDQ39, EQ5 and Zarit scales were administered at baseline and 6 months later. After each session participants filled-out a modified EduPark satisfaction questionnaire and a Likert scale. Educational material was generated for each session after suggestions by participants. RESULTS At baseline PwMSA and caregivers were comparable in age and sex, with significant correlation between UMSARS-IV (disability) and PDQ39 (quality of life). Adherence to sessions was of 94,92 %. Total modified EduPark scores and Likert scales did not differ in PwMSA vs. caregivers, mild-moderate vs. severe-advanced cases or between genders. The significant difference in satisfaction across sessions (p = 0.03) was driven by higher scores in speech, respiratory and occupational therapy sessions. Longitudinally there was no significant worsening in any scale, nor a significant increase post-vs. pre-program in the number of consultations. CONCLUSIONS The healthcare education program in MSA was feasible, satisfactory, and safe for patients and caregivers. The educational material of the program is being forwarded to incident MSA cases attending our clinic.

Abstract
BACKGROUND AND OBJECTIVE Allergic conjunctivitis is the most common type of ocular allergy. The objective of this study was to evaluate the efficacy of a new once-daily, preservative-free, bilastine 0.6% eye drop formulation for the treatment of allergic conjunctivitis. METHODS Two double-masked, vehicle controlled, clinical studies (a Phase 2 Dose Ranging Study and a Phase 3 Efficacy Study) were conducted to assess the efficacy of bilastine ophthalmic solution for the treatment of signs and symptoms of allergic conjunctivitis. Both studies used the Ora-CAC® Conjunctival Allergen Challenge (CAC) Model to allow observations of allergic responses under controlled conditions. Each study was analyzed separately and then combined to create an integrated dataset. RESULTS Efficacy was achieved for the primary efficacy endpoint of ocular itching for three bilastine concentrations (0.2%, 0.4%, and 0.6%) at 15 minutes and 8 hours post-instillation and bilastine 0.6% ophthalmic solution was also efficacious at 16 hours post-instillation. Bilastine 0.6% ophthalmic solution demonstrated non-inferiority to ketotifen 0.025% at the onset of action. From the integrated data set, differences between vehicle and bilastine 0.6% were significant at all time points both at onset (15 minutes) and at a prolonged duration (16 hours) after instillation. CONCLUSION This multi-trial assessment suggests that bilastine 0.6% ophthalmic solution is efficacious for the treatment of the signs and symptoms of allergic conjunctivitis, with a rapid and prolonged duration of action, and has a favorable safety profile. The added convenience of a once-a-day dosing regimen may contribute to patient adherence and improve their quality of life.

Abstract
In the Mediterranean basin, the tick species Hyalomma lusitanicum Koch stands out among other species of the Hyalomma genus due to its wide distribution, and there is great concern about its potential role as a vector and/or reservoir and its continuous expansion to new areas because of climate warming and human and other animal movements. This review aims to consolidate all the information on H. lusitanicum, including taxonomy and evolution, morphological and molecular identification, life cycle, sampling methods, rearing under laboratory conditions, ecology, hosts, geographical distribution, seasonality, vector role and control methods. The availability of adequate data is extremely relevant to the development of appropriate control strategies in areas where this tick is currently distributed as well as in new areas where it could become established in the near future.

Abstract
BACKGROUND Bilastine is a second-generation antihistamine approved for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria. This trial evaluated the efficacy and safety of a new bilastine 0.6% preservative-free eye-drops formulation for the symptomatic treatment of allergic conjunctivitis. METHODS This phase 3, multicenter, double-masked, randomized study evaluated the efficacy, safety and tolerability of bilastine 0.6% ophthalmic solution compared to ketotifen 0.025% and vehicle. The primary efficacy endpoint was ocular itching reduction. The Ora-CAC® Allergen Challenge Model was used to assess ocular and nasal symptoms at 15 minutes (onset of action) and 16 hours post-treatment. RESULTS Subjects (N=228) were 59.6% male, and the mean (SD) age was 44.1 (13.4) years. Bilastine demonstrated efficacy in reducing ocular itching compared to vehicle at both onset of action and 16 hours post-treatment (P <0.001). Ketotifen showed improvement compared to vehicle 15 minutes post-treatment (P <0.001). Bilastine demonstrated statistical non-inferiority to ketotifen for all 3 post-CAC timepoints at 15 minutes post-instillation, based on an inferiority margin of 0.4. Bilastine demonstrated improvement over vehicle (P <0.05) for conjunctival redness, ciliary redness, episcleral redness, chemosis, eyelid swelling, tearing, rhinorrhea, ear and palate pruritus and nasal congestion at 15 minutes post-treatment. Ophthalmic bilastine was safe and well tolerated. Mean drop comfort scores were significantly better (P <0.05) for bilastine compared with ketotifen immediately upon instillation, and similar compared with vehicle. CONCLUSIONS Ophthalmic bilastine effectively reduced ocular itching for 16 hours post-treatment, suggesting that it could be used as a once-daily treatment for the signs and symptoms of allergic conjunctivitis.

Abstract
Background and objectives: Bilastine is a non-sedating second-generation antihistamine for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria. This trial aimed to evaluate the optimal dose, efficacy, and safety of a newly developed once-daily preservative-free ophthalmic formulation of bilastine for allergic conjunctivitis. Methods: This phase 2, single-center, double-masked, randomized study evaluated the efficacy of 3 doses of a bilastine ophthalmic formulation (0.2%, 0.4%, and 0.6%) compared to vehicle for the treatment of allergic conjunctivitis. The primary efficacy endpoint was ocular itching reduction. The Ora-CAC® Conjunctival Allergen Challenge model was used to assess ocular and nasal symptoms at the onset of action (15 minutes), 8- and 16-hours post-treatment. Tolerance and safety were also evaluated. Results: A total of 121 adults with seasonal and/or perennial ocular allergy were randomized. Bilastine ophthalmic formulation 0.2%, 0.4% and 0.6% were significantly superior (p>0.001) to vehicle for the treatment of ocular itching at 3, 5 and 7 minutes post-challenge at onset of action (15 minutes) and 8 hours post-treatment. Bilastine 0.6% was also effective at 16 hours post-treatment. Treatment differences for bilastine 0.6% were statistically significant (p<0.001) compared to vehicle at all timepoints for tearing, eyelid swelling, and nasal symptoms. No relevant adverse events were observed. Conclusions: All the tested ophthalmic bilastine doses were efficacious in rapidly reducing ocular itching. The 0.6% formulation was effective up to 16 hours post-treatment, making it suitable for once-daily administration. The new formulation was safe and well tolerated.

Abstract
Porcine reproductive and respiratory syndrome (PRRS) is a viral disease associated with a decrease in the number of born alive piglets (NBA) and an increase in the number of lost piglets (NLP) per farrowing. Under practical conditions, it is critical to assess whether a farm is suffering PRRSV recirculation in the sow herd as soon as possible. The aim of this research work was to develop a new method to detect potential PRRSV recirculation in sow production farms. Sow reproductive performance records from one farm (farm T) were used to set up the method and records from ten additional farms (farms V1 to V10) were used for validation. A conditional Poisson model of NLP on NBA was proposed to fit the data. A three-step procedure was implemented to detect potential PRRSV recirculation: (i) computation of the maximum-likelihood estimates of the expected values of NBA and NLP in a PRRSV non-recirculating scenario; (ii) calculation, for each farrowing, of the p-value associated with the probability of jointly observing deviations towards decreased NBA and increased NLP. The detection of a potential PRRSV recirculation was based on (iii) the combined p-value resulting from weighing the p-values of the last N farrowings by the chi-square-inverse method. In order to gain specificity, a displacement on the expected non-recirculating NBA and NLP values was used for tuning purposes. With this approach, two PRRSV circulating periods were detected in farm T, which were confirmed with standard laboratorial diagnostic techniques. The method was subsequently validated in farms V1 to V10, where ten PRRSV-recirculating time episodes had been diagnosed. The method proposed here was able to detect the ten PRRSV recirculations using a relatively small set of contiguous farrowings, with only two mismatched weeks, one as a false negative, in farm V1, and one as a false positive, in farm V4. It is concluded that a conditional Poisson-based model of NLP on NBA can be a useful tool for routinely detecting PRRSV recirculation in sow herds.

Abstract
In dairy ruminants, the combination of milking parameters must ensure good milking performance without harming udder conditions. Commonly, milking conditions for goats are established without having checked the admissible limits for optimal and fast milking. The aim of this study was to establish a limit combination of machine milking parameters that improves machine milking performance without altering milkability or udder status. To this end, we studied the effect of 2 combinations (42 kPa, 120 cpm, 60% vs. 44 kPa, 120 cpm, 60% in terms of kilopascals of vacuum level, cycles per minute of pulsator rate, and percentage of pulsator ratio, respectively) on milk production and composition, milk fractioning during milking, SCC, teat tissue thickness variation after milking, and the milk emission kinetics parameters throughout 1 lactation period (6 mo). The 42 and 44 kPa measured at the vacuum gauge level became average values of 37.5 and 39.3 kPa, respectively, measured at the teat sphincter level during milking. Milk flow significantly increased and total milking time decreased 25 s with the elevation of the vacuum level from 42 to 44 kPa without any adverse effect on milk fractioning at milking. However, the use of 44 kPa also showed an increase in tissue thickness above 5%, and we observed a tendency of average conductivity of milk to increase, although without any adverse effect on SCC. It seems that 44 kPa, 120 cpm, 60% is a possible limit combination of parameters to improve milking performance without altering milkability or udder conditions. We concluded that this combination can be used for milking Murciano-Granadina breed goats in conditions similar to those of this study (mid-level milking system and 1 milking/d), although further studies are necessary to verify its application in the case of 2 milkings/d.

Abstract
Background Avian haemosporidian parasites can cause severe disease in their hosts due to excessive exo-erythrocytic merogony and anaemia caused by blood stages. Notably, the development of megalomeronts by species of Haemoproteus and Leucocytozoon has been associated with mortalities in birds. Diagnosis of lethal infections is currently accomplished by the detection of parasites’ tissue stages in histological sections combined with PCR and sequencing. However, sequences frequently are not reliably obtained and the generic discrimination of exo-erythrocytic tissue stages based on morphological characters is challenging. Therefore, the present study aimed at developing specific molecular probes for the identification of Haemoproteus spp. and Leucocytozoon spp. in histological sections using chromogenic in situ hybridization. Methods Parasite subgenus-specific oligonucleotide probes were designed to target the 18S ribosomal RNA of Haemoproteus species (subgenus Parahaemoproteus) and Leucocytozoon spp. (subgenus Leucocytozoon) and were in situ hybridized to sections from formalin-fixed, paraffin-embedded tissue samples determined positive for these parasites by PCR and histopathology. To confirm the presence of parasites at sites of probe hybridization, consecutive sections were stained with haematoxylin–eosin and examined. Results Parahaemoproteus- and Leucocytozoon-specific probes labelled erythrocytic and exo-erythrocytic stages of Haemoproteus spp. and Leucocytozoon spp., respectively. Binding of probes to parasites was consistent with detection of the same exo-erythrocytic meronts in consecutive haematoxylin–eosin-stained sections. Cross-reactivity of the probes was ruled out by negative chromogenic in situ hybridization when applied to samples positive for a parasite of a genus different from the probes’ target. Conclusions Chromogenic in situ hybridization using 18S ribosomal RNA-specific oligonucleotide probes reliably identifies and discriminates Haemoproteus and Leucocytozoon parasites in tissue sections and enables unequivocal diagnosis of haemosporidioses.

Abstract
BACKGROUND The human gut microbiota is assembled during infancy with an increase in diversity and stability. The correct colonization and the establishment of this microbiome are linked to the early and future health status of the individual. It is known that caesarean delivery alters this optimal microbial foundation. C-section (CS) is a common obstetrician surgery; however, it is not without risk for the mother/infant dyad. The World Health Organization recommends not exceeding 10-15% of the total deliveries; nevertheless, this rate has been increasing rapidly worldwide in the last decades. SUMMARY This review discloses the clinical parameters for correct CS recommendation. Moreover, the major microbial changes in the infant gut microbiome acquisition as a consequence of delivery mode and medical practices surrounding it, as well as, the early and long-lasting effects for both mother and babies are discussed. In addition, some strategies for the gut microbiota restoration are analysed. The aim of this review is to show the need for the development of strategies for minimizing or limiting the impact of caesarean on the microbiome development, favouring future health.

Abstract
Several in vitro screening tests have been used for selecting probiotic strains; however they often show low predictive value and only a limited number of strains have demonstrated functionality in vivo. The most used in vitro tests represent a very simplified version of the gut environment, especially since they do not consider the accompanying microbiota. Therefore, there is a need to develop sensitive and discriminating in vitro models including the microbiota. Here we developed an in vitro model to discriminate among microbiotas/fecal waters from different population groups. To this end samples were obtained from seven healthy adults, five IBD-patients, ten full-term and ten preterm newborns. Fecal microbiotas were purified and their impact, as well as that of the fecal waters, on HT29 cells was continuously monitored for 22 h using a real-time cell analyzer (RTCA). The composition of the purified microbiotas was assessed by 16S rRNA gene profiling and qPCR and the levels of short chain fatty acids (SCFA) determined by gas chromatography. The microbiota fractions and SCFA concentrations obtained from IBD-patients, full-term and preterm babies, showed clear differences with regard to those of the control group (healthy adults). Moreover, the purified intestinal microbiotas and fecal waters also differed from the control group in the response induced on the HT29 cells assay developed. In short, we have developed a real-time, impedance-based in vitro model for assessing the functional response induced by purified microbiotas and fecal waters upon intestinal epithelial cells. The capability of the assay for discriminating the functional responses induced, by microbiotas or fecal waters from different human groups, promises to be of help on the search for compounds/strains to restore the functionality of the microbiota-host's interaction.

Abstract
BACKGROUND AND AIMS The aim of this study was to analyze the effects of early overnutrition (EON) on the expression of the renin angiotensin aldosterone system (RAAS) components in renal cortex, renal arteries and renal perivascular adipose tissue (PVAT), as well as the vascular response of renal arteries to Angiotensin II (Ang II). METHODS AND RESULTS On birth day litters were adjusted to twelve (L12-control) or three (L3-overfed) pups per mother. Half of the animals were sacrificed at weaning (21 days old) and the other half at 5 months of age. Ang II-induced vasoconstriction of renal artery segments increased in young overfed rats and decreased in adult overfed rats. EON decreased the gene expression of angiotensinogen (Agt), Ang II receptors AT1 and AT2 and eNOS in renal arteries of young rats, while it increased the mRNA levels of AT-2 and ET-1 in adult rats. In renal PVAT EON up-regulated the gene expression of COX-2 and TNF-α in young rats and the mRNA levels of renin receptor both in young and in adult rats. On the contrary, Ang II receptors mRNA levels were downregulated at both ages. Renal cortex of overfed rats showed increased gene expression of Agt in adult rats and of AT1 in young rats. However the mRNA levels of AT1 were decreased in the renal cortex of overfed adult rats. CONCLUSION EON is associated with alterations in the vascular response of renal arteries to Ang II and changes in the gene expression of RAAS components in renal tissue.

Abstract
INTRODUCTION Surgical management for penile carcinoma is mutilating and affects significantly quality of life. Hereby we present our experience on penile reconstruction (PR) immediately after oncologic resection. MATERIALS AND METHODS We included all patients from January 2007 until April 2012 who underwent PR after partial penectomy (PP). Patients included in the study were seen at four different hospitals. All procedures were done by the same surgeon. Information included were: oncological status at the moment of surgery, surgical technique used for reconstruction. Each case was also registered photographically. On follow-up visits data about outcome and patient's satisfaction were registered. RESULTS During the study period 15 patients underwent PR. Average age at the moment of surgery was 49 years. Average follow-up was 15 months. In 12 patients PR was made at the same time as PP. Of those, four cases underwent glans resurfacing, 2 glandectomy, 6 partial penectomy, and the remaining 3 have had PP in a different time in the past. Every case underwent a split thickness graft procedure. Only 2 patients had postoperative complications. One of them presented urethral stricture and the other graft ischemia. Three patients had positive nodes at the moment of PP and two during the follow-up. None of the cases have presented local recurrence and only one died. On follow-up the remaining patients refer a good quality of life and felt happy with aesthetic results. CONCLUSIONS Given the results presented hereby we propose that PR must be part of the same procedure as the PP.

Abstract
OBJECTIVES To evaluate the effect of Helicobacter pylori (H. pylori) eradication on ulcer bleeding recurrence in a prospective, long-term study including 1,000 patients. METHODS Patients with peptic ulcer bleeding were prospectively included. Prior non-steroidal anti-inflammatory drug (NSAID) use was not considered exclusion criteria. H. pylori infection was confirmed by rapid urease test, histology, or (13)C-urea breath test. Several eradication therapies were used. Subsequently, ranitidine 150 mg o.d. was administered until eradication was confirmed by (13)C-urea breath test 8 weeks after completing therapy. Patients with therapy failure received a second, third, or fourth course of eradication therapy. Patients with eradication success did not receive maintenance anti-ulcer therapy and were controlled yearly with a repeat breath test. NSAID use was not permitted during follow-up. RESULTS Thousand patients were followed up for at least 12 months, with a total of 3,253 patient-years of follow-up. Mean age 56 years, 75% males, 41% previous NSAID users. In all, 69% had duodenal ulcer, 27% gastric ulcer, and 4% pyloric ulcer. Recurrence of bleeding was demonstrated in three patients at 1 year (which occurred after NSAID use in two cases, and after H. pylori reinfection in another one), and in two more patients at 2 years (one after NSAID use and another after H. pylori reinfection). The cumulative incidence of rebleeding was 0.5% (95% confidence interval, 0.16-1.16%), and the incidence rate of rebleeding was 0.15% (0.05-0.36%) per patient-year of follow up. CONCLUSION Peptic ulcer rebleeding virtually does not occur in patients with complicated ulcers after H. pylori eradication. Maintenance anti-ulcer (antisecretory) therapy is not necessary if eradication is achieved. However, NSAID intake or H. pylori reinfection may exceptionally cause rebleeding in H. pylori-eradicated patients.

Abstract
The effects of cooling on the response of cutaneous and non-cutaneous arteries to 5-hydroxytryptamine (5-HT) were analysed.
Segments 2-mm long from rabbit central ear (cutaneous) and femoral (non-cutaneous) arteries were prepared for isometric tension recording in an organ bath at 37 and 24°C (cooling). 5-HT (10−9-3 times 10−4 M) induced concentration-dependent contraction of the arteries. The sensitivity and maximal contraction of ear arteries and only the maximal contraction of femoral arteries to this amine were reduced at 24°C.
Endothelium removal or pretreatment with the nitric oxide synthase inhibitor NG-nitro-l-arginine methyl ester (l-NAME, 10−5 m) did not affect the response at 37°C but reversed the decreased sensitivity at 24°C in ear arteries, and neither procedure modified the reactivity at 24 or 37°C in femoral arteries to 5-HT. At both temperatures, the response of ear arteries to 5-HT was shifted to the right by phentolamine (10−6M) more than by the 5-HT antagonist, ketanserin (3 times 10−7M), and that of femoral arteries was shifted to the right by ketanserin or the 5-HT1/5-HT2 antagonist methysergide (3 times 10−7 M) more than by phentolamine, in arteries with and without endothelium.
These data concur with the proposition that the contraction to 5-HT is mediated mainly by α-adrenergic receptors in ear arteries and mainly by 5-HT-ergic receptors in femoral arteries, and suggest that cooling reduces the sensitivity of cutaneous, but not of deep arteries to 5-HT, probably by endothelium-nitric oxide-dependent mechanisms.

Abstract
Clinical cases of coccidioidomycosis are rare in Argentina and are generally found in the large arid precordilleran area of the country. This study aims to perform a retrospective review of all coccidioidomycosis cases documented in the country from 1892 to 2009, and to describe those occurring in the last 4 years. One hundred and twenty eight cases were documented in the 117 year-period. Since the original description of the disease in 1892 until 1939, only 6 cases were registered; between 1940 and 1999, 59 (6-14/10 yrs) and the remaining 63 (49% of total cases) occurred in the last decade. The median age of 34 patients registered in 2006-2009 was 31 years (range: 7-89), male/female ratio was 1.3:1 and 12 patients were immunocompromised. Twenty-six cases were confirmed by direct microscopy and/or culture whereas the remaining ones by serology. All isolates were identified as Coccidioides posadasii. Thirty patients lived in a vast geographic region with epicenter in Catamarca Valley. Between 2006 and 2009, annual disease incidence rates in Catamarca Province increased from historical values below 0.5/100,000 to 2/100,000 inhabitants. Such increase suggests an emergency of coccidioidomycosis in that region.

Abstract
BACKGROUND It is difficult to find a causal relationship between exposure to Alternaria spores and the development of asthma symptoms in sensitized individuals due to the complexity of clinical situations in which positive diagnostic tests are often found. OBJECTIVE To analyse the diagnostic efficiency of skin testing (ST) and serum-specific IgE to Alternaria, based on the results of a bronchial specific challenge with Alternaria extracts. METHODS Seventy-four asthmatic patients sensitized to Alternaria underwent a specific bronchial challenge with this mould. Skin-testing weal sizes, serum-specific IgE values (CAP-system) and bronchial challenge results were analysed by receiver operating characteristics curves (ROC curves) and logistic regression. The sensitivity, specificity, positive and negative predictive values were calculated for different cut-off points. RESULTS Bronchial challenges to Alternaria elicited a positive result in 45 patients (61%). Skin prick testing almost perfectly predicted the outcome of bronchoprovocation tests (area under the ROC curve of 0.957), whereas intradermal skin testing had moderate efficacy. A negative result for skin prick test (SPT) showed a 4% probability of a positive bronchial challenge in the logistic regression analysis. However, weals around 5.5 mm in diameter had 90% probability of a positive challenge. Quantification of serum-specific IgE correctly classified 86% of the cases. In the logistic regression analysis, a CAP value 16 kU(A)/L predicted a positive bronchial challenge result with 99% accuracy, whereas for a CAP value <0.35 kU(A)/L, this probability was 33%. CONCLUSIONS AND CLINICAL RELEVANCE Most asthmatic patients with positive SPT results to Alternaria would have a positive bronchial challenge. As atmospheric mould levels may vary significantly with the weather conditions, sensitized patients should be instructed on the risk situations, environmental control measures and the importance of correct medication compliance. Immunotherapy with Alternaria could also be taken into account as a valid therapeutic option.

Abstract
The objectives were to determine the effect of administering recombinant bovine ST (bST) every 14 d on milk yield and milk composition in dairy ewes and to assess the possible effects of treatment on milk yield loss that occurs at lamb weaning. Seventy-two lactating dairy ewes were separated into 4 groups at lambing, and each group received no bST (control) or 40, 80, or 120 mg of bST every 14 d until wk 20 of lactation. During the first 5 wk of lactation, ewes suckled their lambs during the night and were milked once daily (period 1). After weaning, from 6 to 22 wk of lactation, ewes were exclusively milked twice daily (period 2). Actual milk yield, potential milk yield, and milk component percentages were recorded weekly throughout lactation. In period 1, bST-treated groups increased yields of potential milk (P = 0.04) and the corresponding 6% fat-corrected milk (FCM; P = 0.04) but not actual milk yield (P = 0.42) compared with the untreated group. In period 2, treated groups increased potential (P < 0.01) and actual (P < 0.01) milk yields as well as their corresponding 6% FCM (potential, P < 0.01; actual, P < 0.01), in comparison with the untreated group. The group treated with 120 mg of bST every 14 d yielded 39% more actual milk and 44% more 6% FCM than the control group for period 2. At weaning, between the last week of period 1 and the first week of period 2, treated groups showed similar absolute (P = 0.15) and relative (P = 0.33) values for the potential milk losses compared with the control group. Treatments increased (P = 0.04) actual milk fat percentages during period 1, but did not affect the other milk components or somatic cell count. In summary, bST increased potential milk yield throughout lactation and actual milk yield only after weaning in dairy ewes. In dairy ewes, bST was not useful for reducing the milk yield loss that occurred at weaning.

Abstract
The initial establishment of lactic acid bacteria (LAB) and bifidobacteria in the newborn and the role of breast-milk as a source of these microorganisms are not yet well understood. The establishment of these microorganisms during the first 3 months of life in 20 vaginally delivered breast-fed full-term infants, and the presence of viable Bifidobacterium in the corresponding breast-milk samples was evaluated. In 1 day-old newborns Enterococcus and Streptococcus were the microorganisms most frequently isolated, from 10 days of age until 3 months bifidobacteria become the predominant group. In breast-milk, Streptococcus was the genus most frequently isolated and Lactobacillus and Bifidobacterium were also obtained. Breast-milk contains viable lactobacilli and bifidobacteria that might contribute to the initial establishment of the microbiota in the newborn.

Abstract
Sediments usually contain many contaminants derived from human activities. In case of dredging activities, these sediment-bound contaminants arise following the excavation and remobilization of sediments. Previous studies have used different species of clam, crabs, lugworms, etc. for the evaluation of dredged material in situ, but there are not studies that use acute bioassays for these purposes. The sea-urchin embryo bioassay has been chosen to characterize biological effects in situ in two ports of the southwest of Spain, the Port of Huelva and the Port of Cadiz. The sea-urchin embryo bioassay has been adapted for in situ evaluation of seawater quality in coastal areas, however, they are necessary for further improvements to take into account differences of temperature between sites. This temperature variation is one of the principal reasons (other than pollution) of larval mortality and the slow down in the growth rate of the urchin. In the present study a bioassay was conducted in both field and laboratory conditions, in order to compare the effects in situ with the effects under controlled conditions of temperature, salinity and oxygen dissolved. Results showed a good correlation between samples obtained in situ and in the laboratory, but in the field the percentage of normal pluteus larvae is less than under laboratory conditions.

Abstract
INTRODUCTION Uterine cervical cancer represents a public health problem in Mexico; the patients suffer physical and psychological stress leading to depression and weight loss. Eating with a relative has positive effects in food ingestion and depressive status in hospitalized patients. In our society, food is the closest way that family members have to bring care and to show affection to the patient that has less appetite as disease goes on. OBJECTIVE To establish the relationship between presence of the family during the meals and depresion, food intake, and weight variation during hospitalization. METHODOLOGY 106 women admitted to the Oncology Department at the General Hospital of Mexico with a diagnosis of CUCA clinical stage II and III were studied in order to improve their condition. Weight and height, diet by means of 24 hour recalls were assessed both at hospital admission and discharge, and Beck's depression inventory was applied; the frequency with which the relatives escorted the patient was recorded. RESULTS Patients were classified in two groups according to the frequency of family escorting; it was found that 43 patients (40.6%) were accompanied, and 63 patients (59.4%) were not. We did not find significant differences in age and days of hospital stay between the groups (p > 0.05). The escorted patients had more foods available during hospitalization (p < 0.05). Energy consumption (kcal) in escorted patients was higher by 12.7% as compared to non-escorted patients. 76.7% of the escorted patients were depressed, as compared to 55% in the non-escorted group. Significant differences were found with regards to clinical status and presence of depression (p < 0.05) between the study groups. CONCLUSIONS Family escorting does not have an influence on the amount of foods consumed during hospitalization or body weight variation; however, it does have an influence on the presence of depression.

Abstract
Water contamination by nitrate is a wideworld extended phenomena. Biological autotrophic denitrification has a real potential to face this problem and presents less drawbacks than the most extended heterotrophic denitrification. Three bench-scale UASB reactors were operated under autotrophic (R1, H2S as electron donor), mixotrophic (R2, H2S plus p-cresol as electron donors) and heterotrophic (R3, p-cresol as electron donor) conditions using nitrate as terminal electron acceptor. 16S rDNA genetic libraries were built up to compare their microbial biodiversity. Six different bacteria phyla and three archaeal classes were observed. Proteobacteria was the main phyla in all reactors standing out the presence of denitrifiers. Microorganisms similar to Thiobacillus denitrificans and Acidovorax sp. performed the autotrophic denitification. These OTUs were displaced by chemoheterotrophic denitrifiers, especially by Limnobacter-like and Ottowia-like OTUs. Other phyla were Bacteroidetes, Chloroflexi, Firmicutes and Actinobacteria that--as well as Archaea members--were implicated in the degradation of organic matter, as substrate added as coming from endogenous sludge decay under autotrophic conditions. Archaea diversity remained low in all the reactors being Methanosaeta concilii the most abundant one.

Abstract
To assess the value of using whole blood samples for the molecular diagnosis of histoplasmosis, we applied an in-house DNA extraction method and a nested PCR targeting a 210 bp specific segment of the Histoplasma capsulatum HcP100 gene. A whole blood volume of 2.5-3 milliliters was centrifuged and the cellular pellet was treated with Trichoderma harzianum lyticase and proteinase K prior to applying a conventional phenol DNA extraction. This procedure allowed complete cell lysis, high DNA yield and specific amplification. The PCR detection limit was 0.25-1 yeast cells/ml of blood sample. The method was assessed on 31 blood samples from 19 patients with microbiological diagnosis of histoplasmosis, 30 healthy persons and 21 patients with other mycoses or mycobacterial diseases. Positive results were obtained in samples from 17/19 patients with histoplasmosis (14/15 immunocompromised and 3/4 without known immunological disorder). Blood samples from the 30 healthy controls and 20 patients with other conditions proved negative; the only false positive result was obtained from a patient with Mycobacterium avium-intracellulare infection. With 89% sensitivity and 98% specificity, this molecular method for detection of the agent in blood shows promising for the rapid diagnosis of human histoplasmosis.

Abstract
The incidence of fungemia has increased over the past decade. Multiple-species candidemia (MSC) has been infrequently reported. From 1998 to 2004, of 155 patients with diagnosis of candidemia at the Hospital de Clinicas (University of Buenos Aires), seven cases of MSC were identified (6 adults and 1 newborn) and compared with 21 cases of similar age and sex with monomicrobial candidemia. There were no differences in clinical data and outcome, except for the mediana duration of hospital stay (39 days for patients with MSC vs. 18 days for patients with monomicrobial candidemia, the mean time of central venous catheter permanence previous to candidemia (32 days for patients with MSC vs. 12 days for patients with monomicrobial candidemia and the duration of candidemia (5 days for MSC and 1 day for monomicrobial candidemia. In conclusion, although MSC episodes are less common than those caused by monomicrobial candidemia, modifiable risk factors such as duration of hospitalization and central venous catheter permanence account for the development of MSC.

Abstract
Since 1994 the results of the analyses of key chemical compounds (trace metals, polychlorinated biphenyls and polycyclic aromatic hydrocarbons) and the comparison with the corresponding sediment quality guidelines (SQGs) are used in decision-making for dredged material management in Spain. Nonetheless in the last decades a tiered testing approach is promoted for assessing the physical and chemical characteristics of dredged sediments and their potential biological effects in the environment. Bioassays have been used for sediment toxicity assessment in Spain but few or no experiences are reported on harbour sediments. We studied the incidence of toxicity in the 7 d bioassay using rotifers (Brachionus plicatilis) and the 48 h bioassay using sea urchin (Paracentrotus lividus) embryos over a series of experiments employing 22 different elutriates. The relative performance of this exposure phase was not comparable to data on the 10-d acute toxicity test using the burrowing amphipod Corophium volutator and the polychaete Arenicola marina, carried out on the whole sediments. These results evidence the importance of the exposure route and the test selected in decision-making, as the toxicity registered for the undiluted elutriates was largely due to the different solubility of sediment-bound contaminants. This work and other studies indicate that for many sediments, a complete battery of test is recommended together with physico-chemical analyses to decide whether dredged sediments are suitable for open water disposal or not.

Abstract
The rate of oxalate absorbed from intestine is highly influenced by calcium intake in healthy subjects. It is unknown whether commonly used phosphate binders modify intestinal absorption and renal excretion of oxalate in chronic kidney disease (CKD) patients. This study aims to determine if calcium carbonate or sevelamer influences on urinary oxalate excretion. Twenty patients with CKD (stage 4 and 5 pre-dialysis) were included. Two treatment (1500 mg of calcium carbonate or 2400 mg of sevelamer), two-period (21 days each), crossover study with balanced assignment of the order of administration, and two washout periods were the main characteristics of this study design. Laboratory analyses in each phase included: serum creatinine, calcium, phosphorus, bicarbonate, total cholesterol, and 24 h urinary excretion of oxalate, creatinine, and urea. Creatinine clearance, protein catabolic rate (PNNA), total urinary oxalate excretion, and urinary oxalate / creatinine ratio were determined. Seventeen patients completed both treatment sequences. Total urinary oxalate excretion and urinary oxalate / creatinine ratios decreased significantly with respect to washout periods either after sevelamer or calcium carbonate treatment. The decrease in urinary oxalate excretion was greater after calcium carbonate (41.2+/-17.4%) than after sevelamer treatment (30.4+/-23.8%). There were not significant changes in renal function or PNNA values throughout the study periods. In conclusion, either calcium carbonate or sevelamer significantly reduces urinary oxalate excretion in CKD patients. Further studies will be needed to ascertain whether the type of phosphate binder influences on the accumulation of oxalate in CKD patients.
