Objective Physiological bicarbonate/lactate-based solutions may correct acidosis in a better way than standard lactate-based solutions. In this study, a new 25 mmol/L bicarbonate/10 mmol/L lactate peritoneal dialysis (PD) solution was compared with a standard 35 mmol/L lactate solution. Design This was a prospective open label study. All patients had a 2-week baseline period using the standard lactate solution, followed by 8 weeks on the bicarbonate/lactate solution and 2 weeks on the lactate-basedsolution. Setting Four Danish and four Spanish nephrology centers. Patients 40 well-dialyzed (creatinine clearance > 55 L/week/1.73 m2 body surface area) patients on continuous ambulatory PD. Interventions Blood samples were taken for biochemistry (including venous blood gases) at week –2, day 1, weeks 2, 4, and 8, and at follow-up. A physical examination, a peritoneal equilibration test (PET), and quality of life (K/DQOL), ultrafiltration, and adequacy assessments were performed at baseline and at week 8. Vital signs and other safety parameters were followed at each visit. Extraneal (Baxter Healthcare, Castlebar, Ireland) was used by all patients for the long dwell. Main Outcome Measure Effect on the venous plasma bicarbonate level. Results Venous plasma bicarbonate levels rose from 24.4 mmol/L when patients were on the pure lactate to 26.1 mmol/L when using the bicarbonate/lactate solution ( p < 0.001). When patients were using the bicarbonate/lactate solution, 66% of values were maintained within the venous normal range of 24 – 30 mmol/L, versus 46.2% when patients were on the pure lactate solution ( p < 0.001). There were no adverse findings with respect to clinical symptoms, vital signs, or physical examination. The PET and adequacy, ultrafiltration, and K/DQOL assessment results were unchanged. Conclusions The new 25 mmol/L bicarbonate/10 mmol/L lactate solution provided better correction of acidosis than an equivalent 35 mmol/L standard lactate solution, without any safety issues.

Abstract This study examined knowledge of sea lions (Zalophus wollebaeki) for both residents and tourists on San Cristóbal Island in the Galápagos, a famous nature tourism destination. Participants (N = 281) obtained through convenience and snowball sampling answered questionnaires about their knowledge of sea lions. Participants with higher education received higher overall scores, but participants’ education and age influenced answers on only a few questions. Residents and tourists obtained comparable overall scores, exhibiting extensive knowledge of sea lion behavior and life history. Whether participants were residents or tourists influenced answers to several questions, but when only participants with 13 years of education or more were examined, few differences in answers remained between residents or tourists. Participants’ broad knowledge of sea lions may be attributed to the items of knowledge tested, participants’ motivations for travel to the Galápagos, and the fact that sea lions are an engaging and ubiquitous animal.

This study focuses on the comparative analysis of variables related to the trophic niche plasticity in the Galapagos sea lion (Zalophus wollebaeki). There is great concern regarding the future of this species, so study of the diet and the way these animals obtain their food is useful to understand and predict their survival possibilities in the long term. The combined use of scat analysis and stable isotopes helps to determine foraging habits of this species in greater detail. The objective of the study was to assess the feeding habits of Z. wollebaeki and its space–time variation. The scat analysis (n = 200) gave as a result space–time changes in the foraging strategies of this species. The isotopic values (n = 80) showed differences in relation to foraging grounds (δ13C: P = 0.001), but also suggested an apparent stability in the trophic level of their diet (δ15N: P = 0.084). These results constitute a relevant finding in the evolutionary behaviour of the species, showing that Z. wollebaeki has developed a high degree of plasticity in its foraging habits that may improve its survival in a highly demanding ecosystem in terms of limited and fluctuating resources.
