Abstract
Satellite tracking is a key tool for studying sea turtles in the wild. Most tracking has been performed on adult females however, leaving knowledge gaps regarding other population segments, such as adult males. By satellite tracking 12 male green turtles (Chelonia mydas) at a breeding site in West Africa, we describe their movements from the breeding to the foraging grounds and compare migrations with those of 13 females tracked in the same season. During the mating period, some males remained near the focal nesting site, while others performed exploratory movements, apparently to visit other nearby rookeries. Males migrated on average shorter distances to foraging grounds (377 km, range 50-1081, n = 9) compared to females (1038 km, range 957-1850, n = 11]). Importantly, male foraging areas overlapped with previously described areas for females, suggesting sex-specific migration distances are not derived from differences in habitat selection. Strong support for differential migration by sex in sea turtles has hitherto been found in just one other species, but indications are that it may be a general feature in this group. These findings have important implications for our understanding of the interplay between reproductive roles and movement ecology of these emblematic animals.

Abstract
BackgroundSjögren Syndrome (SS) is a systemic autoimmune systemic disease which mainly affects the exocrine glands, presenting mainly as persistent eye and mouth dryness as a result of a functional impairment of the lacrimal and saliva glands. Cutaneous vasculitis is one of the most characteristic extraglandular manifestations, especially in patients with anti-Ro antibodies. Although vasculitis may affect a wide range of organs and systems, the clinical characteristics and the diversity of vasculitis associated with SS have not been thoroughly studied.ObjectivesTo describe the clinical and analytical characteristics of patients with SS and cutaneous, or systemic vasculitis, as well as their outcome.MethodsRetrospective, descriptive study, of patients with primary SS and vasculitis attended at a Tertiary Hospital. Collected data were analysed using the SPSS statistical package. Quantitative data were expressed as a mean +/- 2SD and qualitative data as a proportion. A p-value 0.05 was considered significant.ResultsFrom a total of 395 patients with primary SS, 53 patients presented with both SS and vasculitis (51, 96.2%, women). The mean age at diagnosis was 56.12 (±2.17) years. Globally, 84.9% of patients met the 2002 classification criteria; 90.6% the 2012 criteria, and 83.0% the 2016 criteria. Thirty-two (60.4%) patients presented with cutaneous vasculitis (mainly purpura), and 7 (13.2%) with systemic vasculitis with renal, neurological and/or lung involvement. Extraglandular manifestations were frequent. Out of the 53 patients, twenty-five (47.2%) presented pulmonary involvement; 43(81.1%) articular involvement (19 [35.8%] arthritis); 21(39.6%) Raynaud phenomenon, and 15.1% peripheral neuropathy. Six (11.3%) patients developed a lymphoma. All patients presented positive ANA; 69.8% anti-Ro60, 52.8% anti-La, 75.5% RF; 62.3% polyclonal hypergammaglobulinemia; 33.9% cryoglobulins, 58.5% elevated beta2-microglobulin levels, and 12 (22.65%) hypocomplementemia (4 decreased C3, and 8 decreased C4). Biopsy specimens showed in 8 (15.9%) cases urticaria vasculitis; in 1 (1.9%) PAN; in 2 (3.8%) Cryoglobulinaemic vasculitis, in 5 (9.4%) ANCA associated vasculitis (4 PAM-MPO, and 1 GPA-PR3); and in 1 SNC vasculitis. 64.2% of patients received glucocorticoids and 37.7% hydroxychloroquine. 5 (9.4%) patients received Rituximab. Vasculitis were significantly more frequent in patients with anti-Ro60 (p=0.005, OR2.5 IC95% 1.33-4.74); anti-La (p=0.009, OR 2.39, IC95% 1.29-4.43); RF (p<0.000, OR 3.78, OR 3.72 IC95%1.90-7.26); C4 hypocomplementemia (p<0.00, OR 6.42, IC 95% 2.65-15.56); cryoglobulins (p=0.016, OR 2.29, IC95% 1.21-4.33); hypergammaglobulinemia (p=0.004, OR 2.53, IC95% 1.36-4.71), arthritis (p= 0.001, OR 3.26, IC95% 1.72-6.19), lung fibrosis (p=0.010, OR 2.92, IC95% 1.38-6.17) and lymphoma (p=0.011, OR 4.05, IC95% 1.5-10.94).ConclusionIn our series, most patients with SS presented repetitive flares of cutaneous vasculitis as previously reported. Nonetheless, our patients showed a greater proportion of lung and articular manifestations as well as anti-La positivity.Five patients presented with ANCA associated vasculitis, which represents and exceedingly rare and severe manifestation in this context.Patients with SS may present a wide range of vasculitis, ranging from the most common leucocytoclastic vasculitis to the more severe systemic vasculitis, such as: AAV and cryoglobulinaemic vasculitis.The association of SS with vasculitis is more common in patients with anti-Ro, anti-La and/or RF, hypocomplementemia, cryoglobulins and hypergammaglobulinemia.References[1]Ramos-Casals, M., Anaya, J., García-Carrasco, M., Rosas, J., Bové, A., Claver, G., Diaz, L., Herrero,[2]C. and Font, J., 2004.

Abstract
OBJECTIVE To evaluate the incidence and risk factors for early mortality (EM) in the ICU in patients with community-acquired septic shock (CASS). DESIGN A retrospective cohort study of patients with CASS admitted to the ICU (2003-2016). SETTING ICU at a University Hospital in Spain. PATIENTS All consecutive patients admitted to the ICU with CASS. INTERVENTIONS None. MAIN VARIABLES OF INTEREST CASS was defined according to the Sepsis-3 definitions. EM were defined as occurring within of 72h following ICU admission. A multinomial logistic regression analysis was performed to identify the risk factors associated with early deaths. RESULTS During the study period, 625 patients met the Sepsis-3 criteria and admitted with CASS. 14.4% of all patients died within the first 72h. Of 161 patients who died in the ICU, 90 (55.9%) died within the first 72h. The percentage of early and late mortality did not vary significantly during the study period. The need and adequacy of source control were significantly lower in patients with EM. In the multivariate analysis, ARDS, non-respiratory infections, bacteremia and severity at admission were variables independently associated with EM. The only factor that decreased EM was adequate source control in patients with infections amenable to source control. CONCLUSIONS The incidence of EM has remained stable over time, which means that more than half of the patients who die from CASS do so within the first 72h. Infections where adequate source control can be performed have lower EM.

Abstract
Changes in the foraging environment and at-sea distribution of southern elephant seals from Kerguelen Islands were investigated over a decade (2004-2018) using tracking, weaning mass, and blood δ13C values. Females showed either a sub-Antarctic or an Antarctic foraging strategy, and no significant shift in their at-sea distribution was detected between 2004 and 2017. The proportion of females foraging in sub-Antarctic versus Antarctic habitats did not change over the 2006-2018 period. Pup weaning mass varied according to the foraging habitat of their mothers. The weaning mass of sub-Antarctic foraging mothers' pups decreased by 11.7 kg over the study period, but they were on average 5.8 kg heavier than pups from Antarctic foraging mothers. Pup blood δ13C values decreased by 1.1‰ over the study period regardless of their sex and the presumed foraging habitat of their mothers. Together, these results suggest an ecological change is occurring within the Indian sector of the Southern Ocean with possible consequences on the foraging performance of southern elephant seals. We hypothesize that this shift in δ13C is related to a change in primary production and/or in the composition of phytoplankton communities, but this requires further multidisciplinary investigations.

Abstract
OBJECTIVE To analyze the profile, incidence of life support therapy limitation (LSTL) and donation potential in neurocritical patients. STUDY DESIGN A multicenter prospective study was carried out. SETTING Nine hospitals authorized for organ harvesting for transplantation. PATIENTS All patients consecutively admitted to the hospital with GCS < 8 during a 6-month period were followed-up until discharge or day 30 of hospital stay. STUDY VARIABLES Demographic data, cause of coma, clinical status upon admission and outcome were analyzed. LSTL, brain death (BD) and organ donation incidence were recorded. RESULTS A total of 549 patients were included, with a mean age of 59.0 ± 14.5 years. The cause of coma was cerebral hemorrhage in 27.0% of the cases.LSTL was applied in 176 patients (32.1%). In 78 cases LSTL consisted of avoiding ICU admission. Age, the presence of contraindications, and specific causes of coma were associated to LSTL. A total of 58.1% of the patients died (n=319). One-hundred and thirty-three developed BD (24.2%), and 56.4% of these became organ donors (n=75). The presence of edema and mid-line shift on the CT scan, and transplant coordinator evaluation were associated to BD. LSTL was associated to a no-BD outcome. Early LSTL (first 4 days) was applied in 9 patients under 80 years of age, with no medical contraindications for donation and a GCS ≤ 4 who finally died in asystole. CONCLUSIONS LSTL is a frequent practice in neurocritical patients. In almost one-half of the cases, LSTL consisted of avoiding admission to the ICU, and on several occasions the donation potential was not evaluated by the transplant coordinator.

Abstract
BACKGROUND Both human and murine studies suggest that anti-inflammatory drugs prevent intestinal neoplasia. The purpose of this study was to investigate the role of aspirin as a chemopreventive agent for colorectal cancer. METHODS We administered aspirin to the Min/+ mouse, an animal with a germline mutation in Apc, a gene that is essential for normal epithelial cell growth and differentiation. Apc mutation increases cytoplasmic beta-catenin, a regulatory protein associated with the cytoskeleton. Min/+ mice develop multiple intestinal adenomas and exhibit altered cell growth in the preneoplastic intestinal epithelium. RESULTS Aspirin decreased the rate of tumor formation in Min/+ mice by 44%. Aspirin also normalized enterocyte growth by increasing apoptosis and proliferation in the preneoplastic intestinal mucosa. Finally, aspirin produced a decrease in intracellular beta-catenin levels, suggesting that modulation of this protein is associated with tumor prevention. CONCLUSIONS These data confirm a role for aspirin in suppression of Apc-associated intestinal carcinogenesis.

Abstract
An indirect enzyme-linked immunosorbent assay (ELISA) for the serodiagnosis of Brucella ovis infection was developed. The assay uses a mouse monoclonal antibody to bovine IgG1 horseradish peroxidase (HRPO) conjugate that cross-reacts with immunoglobulin from sheep and a purified antigen from Brucella ovis. The ELISA data were read and analyzed according to a targeting procedure. The ELISA results were compared with a cold complement fixation test (CFT). Sera from 675 rams from three uninfected flocks were used to determine the ELISA cut-off value (O.D. 405 nm: 0.095) and the diagnostic specificity of the ELISA (100%) and the CFT (99.69% +/- 0.42). The ELISA cut-off value was corroborated by receiver operating characteristic (ROC) analysis. Six hundred and forty semen and serum samples from 419 rams from two naturally infected flocks were collected before and after mating-time during two consecutive years. All semen samples were cultured and Brucella ovis was isolated from 28 samples. Sera from the 28 rams with positive semen were used to determine the diagnostic sensitivity of the ELISA (96.43% +/- 6.8) and of the CFT (including suspected positive samples with titers of 1:5; 88.89% +/- 11.85). Considering the CFT suspicious and the anti-complementary reactions as positive resulted in a diagnostic sensitivity value of 89.28% +/- 11.46. Six hundred and ten serum samples from the 640 sera were used to determine relative sensitivity (excluding sera with 1:5) at: ELISA/CFT 97.26% +/- 3.74 and CFT/ELISA was 71.72% +/- 8.87. The percent agreement, beyond chance measured by the Kappa index was 79.7. Relative sensitivity ELISA/CFT (including 1:5 titers in the CFT as positive) was 94.9% +/- 4.83 and CFT/ELISA was 72.84% +/- 8.59. The Kappa index was 79.4.

Abstract
OBJECTIVE To analyze the clinical and economic consequences of the implementation of a weaning protocol in patients mechanically ventilated (MV) for more than 48 h. DESIGN Comparative study. SETTING General intensive care unit (ICU) in a county hospital covering 360000 inhabitants. PATIENTS 51 patients weaned by a fixed protocol were studied prospectively and compared with 50 retrospective controls. MEASUREMENTS The following variables were assessed: Acute Physiology and Chronic Health Evaluation (APACHE) II score, age, cause of respiratory failure, type of extubation (direct extubation or extubation using a weaning technique), number of days on MV before the weaning trial, weaning time, total duration of MV, complications (reintubations and tracheostomies), length of ICU stay, and mortality. RESULTS The groups were comparable in terms of age, APACHE II score, and main cause of acute respiratory failure. Number of days on MV up to the weaning trial were similar in the two groups (8.4 +/- 7.7 in the protocol group vs 7.5 +/- 5.5 in the control group, NS). Most of the patients (80%) in the protocol group were directly extubated without a weaning technique, unlike the control group (10%) (p < 0.01). When a weaning technique was used, the weaning time was similar in both groups (3.5 +/- 3.9 days vs 3.6 +/- 2.2 days in the control group). Duration of MV was shorter in the protocol group (10.4 +/- 11.6 days) than in the control group (14.4 +/- 10.3 days) (p < 0.05). As a result, the ICU stay was reduced by using the weaning protocol (16.7 +/- 16.5 days vs 20.3 +/- 13.2 days in the control group, p < 0.05). We found no differences in reintubation rate (17 vs 14% in the control group) and need for tracheostomies (2 vs 8% in the control group). CONCLUSION The implementation of a weaning protocol decreased the duration of MV and ICU stay by increasing the number of safe, direct extubations.

Abstract
OBJECTIVE To evaluate the relationship between PaCO2 and end-tidal CO2 tension (PetCO2) before weaning and during a weaning trial and to determine the ability of PetCO2 to identify clinically relevant episodes of hypercapnia. DESIGN Open, prospective study. SETTING General intensive care unit. PATIENTS 30 critically ill patients (mean age 63 +/- 2 years; Acute Physiology And Chronic Health Evaluation (APACHE) II of 18.4 +/- 3) who underwent a weaning trial during the recovery phase of acute respiratory failure requiring mechanical ventilation (MV) (8.9 +/- 1 days on MV). INTERVENTIONS Weaning trial consisted of 2 h breathing on 5 cmH2O of Continuous Positive Airway Pressure (CPAP). MEASUREMENTS AND RESULTS Arterial blood gas values, PetCO2 register and pulse oximetry determinations were recorded in assist/control ventilation before CPAP, after 1 h on CPAP and after 2 h on CPAP (immediately before extubation) or immediately before returning to assist/control mode in patients who failed the weaning trial. Clinically relevant hypercapnic episodes were described as: (1) an increment in PaCO2 > 42 mm Hg in previously normocapnic patients and (2) an increment of > 8 mm Hg from previous PaCO2 in previously hypercapnic patients. Changes in PaCO2 and changes in PetCO2 between MV and the first and second hour of CPAP showed a significant correlation (r = 0.74; p < 0.01). Clinically relevant hypercapnic episodes were detected by increments of > 3 mm Hg in PetCO2 with a sensitivity of 82%, a specificity of 76% and a negative predictive value of 94%. The area under the receiver operating characteristic curve for increments in PetCO2 was 0.90. CONCLUSIONS Capnography provided good assessment of hypercapnic episodes during weaning, although the high number of false positives may result in arterial blood sampling in patients who do not present with ventilation failure.

Abstract
Hair mercury analysis was carried out on a sample of 219 people living in the main gold mining zone of Colombia, 27 inhabitante of Cartagena City being taken as control sample. For data analysis the sample was divided by occupation and the corresponding the hair mercury concentrations (mean +/- SD) were found to be 5.23 +/- 5.78, 2.83 +/- 3.27, 2.4 +/- 2.02 and 1.33 +/- 0.74 micrograms/g for fishermen, miners, people of various other activities and the control sample, respectively. According to variance analysis and the Newman Keuls test, there were significant differences (p < 0.01) between the mercury concentrations for fishermen and those for the other groups. No significant differences were found for hair mercury and sex, non was any correlation with age detected; however, a low positive correlation (R = 0.15, p < 0.01) with the frequency of the consumption of fish was noted. The main symptoms of mercury poinsoning observed in the persons exposed were headache, oral lesions, metalic taste, loss of memory, and irritability.

Abstract
OBJECTIVE To determine whether continuous subglottic aspiration prevents nosocomial pneumonia in mechanically ventilated patients. DESIGN A randomized, controlled, blinded study. SETTING Medical-surgical intensive care unit. PATIENTS 190 patients who were admitted to the intensive care unit during a 33-month period and whose condition suggested the need for prolonged intubation (> 3 days). INTERVENTION 76 patients were randomly allocated to receive continuous aspiration of subglottic secretions, and 77 control patients were allocated to receive usual care. MEASUREMENTS The numbers of cases of ventilator-associated pneumonia, ventilated days, days in intensive care unit, and deaths were recorded. The amount of subglottic secretions aspirated daily and surveillance cultures in the subglottic secretions were also obtained periodically. Etiologic diagnosis was based on the quantitative culture of secretions obtained by protected specimen brush or bronchoalveolar lavage. RESULTS The incidence rate of ventilator-associated pneumonia was 19.9 episodes/1000 ventilator days in the patients receiving continuous aspiration of subglottic secretions and 39.6 episodes/1000 ventilator days in the control patients (relative risk, 1.98; 95% CI, 1.03 to 3.82). This difference was due to a significant (P < 0.03) reduction in the number of gram-positive cocci and Haemophilus influenzae organisms in the patients receiving continuous aspiration. However, no differences were observed in the number of Pseudomonas aeruginosa or Enterobacteriaceae organisms. Episodes of ventilator-associated pneumonia occurred later in patients receiving continuous aspiration (12.0 +/- 7.1 days) than in the control patients (5.9 +/- 2.1 days) (P = 0.003). The same microorganisms isolated from protected specimen brush or bronchoalveolar lavage cultures in patients with ventilator-associated pneumonia were previously isolated from cultures of subglottic secretions in 85% of cases. No significant differences in outcome were found. CONCLUSIONS The incidence of nosocomial pneumonia in mechanically ventilated patients can be significantly reduced by using a simple method that decreases the chronic microaspirations through the cuff of endotracheal tubes.

Abstract
Dexamethasone was administered orally for 7.5 or 10 d to each of 20 pregnant bitches beginning at an estimated 28 to 51 d of gestation, using 1 of 2 dose regimens. Five bitches were given dexamethasone 3 times a day for 10 d, with the highest dose of 0.2 mg/kg for 5 d and then at progressively decreasing doses of 0.16-0.02 mg/kg for 5 d. The 15 remaining bitches were given dexamethasone 2 times a day for 7.5 d, increasing from 0.1 to 0.2 mg/kg over the first 3 administrations, then remaining at 0.2 mg/kg on Days 2 to 5, and decreasing from 0.16 to 0.02 mg/kg over the last 5 administrations. The side effects, including mild polydipsia and polyuria, disappeared when treatment was discontinued. Depending on the stage of pregnancy, uterine contents were either resorbed or aborted, or both. Pregnancy was terminated within 2 to 16 d after the start of treatment in all treated bitches, at 2 to 5 d of treatment in 2 of 3 bitches treated at 40 to 51 d of pregnancy, and at 0 to 4 d after the end of treatment in most of the 17 bitches treated at 28 to 35 days of pregnancy. Oral administration of dexamethasone appears to be a potentially useful pharmacologic treatment for the termination of unwanted pregnancy in the bitch.

Abstract
OBJECTIVE To study the effect of positive end-expiratory pressure (PEEP) on right ventricular hemodynamics and ejection fraction in patients with chronic obstructive pulmonary disease and positive alveolar pressure throughout expiration by dynamic hyperinflation (auto-PEEP). DESIGN Open, prospective, controlled trial. SETTING General intensive care unit of a community hospital. PATIENTS Ten patients sedated and paralyzed with an acute exacerbation of chronic obstructive pulmonary disease undergoing mechanical ventilation. INTERVENTIONS Insertion of a pulmonary artery catheter modified with a rapid response thermistor and a radial arterial catheter. PEEP was then increased from 0 (PEEP 0) to auto-PEEP level (PEEP = auto-PEEP) and 5 cm H2O above that (PEEP = auto-PEEP +5). MEASUREMENTS At each level of PEEP, airway pressures, flow and volume, hemodynamic variables (including right ventricular ejection fraction by thermodilution technique), and blood gas analyses were recorded. MAIN RESULTS The mean auto-PEEP was 6.6 +/- 2.8 cm H2O and the total PEEP reached was 12.2 +/- 2.4 cm H2O. The degree of lung inflation induced by PEEP averaged 145 +/- 87 mL with PEEP = auto-PEEP and 495 +/- 133 mL with PEEP = auto-PEEP + 5. The PEEP = auto-PEEP caused a right ventricular end-diastolic pressure increase, but there was no other significant hemodynamic change. With PEEP = auto-PEEP + 5, there was a significant increase in intravascular pressures; this amount of PEEP reduced cardiac output (from 4.40 +/- 1.38 L/min at PEEP 0 to 4.13 +/- 1.48 L/min; p < .05). The cardiac output reduction induced by PEEP = auto-PEEP + 5 was > 10% in only five cases and this group of patients had significantly lower right ventricular volumes than the group with less cardiac output variation (right ventricular end-diastolic volume: 64 +/- 9 vs. 96 +/- 26 mL/m2; right ventricular end-systolic volume: 38 +/- 6 vs. 65 +/- 21 mL/m2; p < .05) without significant difference in the other variables that were measured. Neither right ventricular ejection fraction nor right ventricle volumes changed as PEEP increased, but there were marked interpatient differences and also pronounced changes in volume between stages in individual patients. CONCLUSIONS In the study conditions, PEEP application up to values approaching auto-PEEP did not result in the impairment of right ventricular hemodynamics, while higher levels reduced cardiac output in selected patients.

Abstract
To determine the usefulness of samples obtained by bronchoalveolar lavage (BAL) in establishing the diagnosis of ventilator-associated pneumonia, quantitative cultures of BAL and protected specimen brush (PSB) samples obtained via fiberoptic bronchoscope were compared in 42 patients with suspected ventilator-associated pneumonia. Direct examination of BAL fluid was also used to identify cells with intracellular organisms. Ventilator-associated pneumonia was diagnosed in 18 patients; a total of 39 microorganisms were recovered from BAL fluid and 29 from PSB specimens. Cultures of 21 BAL and 23 PSB specimens were sterile. Quantitative BAL and PSB cultures coincided in 76% of cases. Sterile BAL and PSB cultures agreed in 87% of cases. Cultures were completely discordant in only three cases. The sensitivity of BAL for diagnosis of ventilator-associated pneumonia using bacterial counts of > or = 10(4) cfu/ml was 89%, and specificity was 100%. In 14 of the 18 patients with ventilator-associated pneumonia, the percentage of cells containing intracellular organisms in specimens recovered by BAL was 11.6% versus 0.45% in patients without pneumonia (p < 0.05). In the remaining four patients, all of whom had Pseudomonas aeruginosa pneumonia, no intracellular organisms could be detected. Using a cut-off point of > or = 5% of cells with intracellular organisms, the sensitivity and specificity for the early diagnosis of ventilator-associated pneumonia was 67% and 96%, respectively. The results confirm the usefulness of the quantitative BAL culture (with a cut-off at 10(4) cfu/ml) for the diagnosis of ventilator-associated pneumonia. The identification of intracellular organisms in BAL fluid is a good early indicator of pneumonia, but the sensitivity of this technique may be lower for Pseudomonas aeruginosa infections.

Abstract
The aim of this study was to evaluate the prevalence of asymptomatic bacteriuria and its prognostic factors in a geriatric population living in a nursing home. Seventy-eight patients (68 females, 10 males) with a mean age of 82 +/- 6 years (range: 60-94) were studied. Once symptomatic infection is ruled out and the risk factors had been analyzed, a urine culture was performed in all cases. We then identified two different population groups: asymptomatic bacteriuria without risk factors (group A), and asymptomatic bacteriuria with risk factors (group B). Overall prevalence of asymptomatic bacteriuria was 38.5% (Group A: 23%, group B: 63%; p < 0.001). Considering all patients with bacteriuria, 50% of cases (15 out of 30 patients) had urine incontinence, 40% suffer from severe limitation of movements and 70% had a past history of pregnancy. The same figures for the population with negative urine culture were 12.5%, 14.5%, and 46% respectively (p < 0.01). In group B, 79% of cases had more than one RF, including all patients with the association of urine incontinence, movement limitation and diabetes. In group A, 93% of asymptomatic bacteriuria were due to E. coli with low adhesin expression (27%) whereas in group B, E. coli was isolated in 44% asymptomatic bacteriuria cases, with high adhesin expression (71.5%), other enteric gram-negative bacilli (31%), non-fermentative gram-negative bacilli (19%) and gram-positive cocci (6%). Group A patients were treated with a single dose of ciprofloxacin (500 mg) with elimination of bacteria in urine in 91% of cases (at one week) and 73% of cases (at one month).(ABSTRACT TRUNCATED AT 250 WORDS)
