| 9 | Comparison of Secnidazole and Fenbendazole for the Treatment of Asymptomatic Giardia Infection in Dogs显示文摘The objetive of this study was to compare a single dose of secnidazole versus multiple doses of fenbendazole for the treatment of dogs with asymptomatic Giardia infection.Materials and methods:Twenty-four asymptomatic dogs with a positive test result for Giardia spp were randomized in two equal groups to receive a single dose of secnidazole at 30 mg/kg PO,or fenbendazole at 50 mg/kg PO q24h for 3 days.Hematological parameters were evaluated before and 8 days after treatment,and feces were re-examined at days 8,15,and 30 post-treatment by fecal flotation and antigen test.Results:The number of positive dogs in the fenbendazole group was:1(day 8)and 3(days 15 and 30).In the secnidazole group,the number of positive cases were:4(day 8),3(day 15),and 1(day 30).Conclusion:Treatment with secnidazole or fenbendazole,were effective between 75%and 92%to eliminate the excretion of Giardia cysts in canines together with hygienic measures to control,like disinfection with quaternary ammonium of patients and their environment.Further studies that include more animals and multiple fecal exams on consecutive days would be necessary to confirm its efficacy in dogs. | Jhon D Ruiz Gloria P Ramírez Ana M Múnera Carlos Arroyave Laura Castano Pablo López | 2019 | Veterinary Science Research2019，1，1： | 0 |

| 11 | Evaluation of Cuban Bacillus thuringiensis(Berliner,1911)(Bacillales:Bacillacea)isolates with larvicidal activity against Aedes aegypti(Linnaeus,1762)(Diptera:Culicidae)显示文摘Objective:To evaluate 11 Cuban native Bacillus(B.)thuringiensis isolates in order to select one with the best larvicidal activity against Aedes(Ae.)aegypti and low cytotoxicity.Methods:The cry and cyt genes of the isolates(A21,A51,L95,L910,M29,R84,R85,R87,R89,U81 and X48)were amplified by PCR.The influence of organic matter and NaCl on the larvicidal activity was tested by bioassays.Cytotoxicity was assayed on peritoneal macrophages of BALB/c mice.Results:The cyt1(Aa,Ab,Ba),cyt2,cry4aA,cry4Ba,cry11(Aa,Ba,Bb)and cry10 genes were identified in all native Cuban isolates.The larvicidal activity(LC_(90))of seven isolates was affected by the presence of organic matter in the water,while A21,A51,L910,R84,U81 and X48 had better LC_(50),LC_(90),LC_(95) than the 266/29-Ⅶ-98 control strain.The LC_(50) of two isolates was affected by the presence of NaCl and A21,A51,R85 isolate had better larvicidal activity than the 266/29-Ⅶ-98 control strain.In terms of toxicity against macrophages,the extracts of nine isolates were less cytotoxic than the control strains.Conclusions:Native isolate A21 had the main virulence factors against Ae.aegypti larvae,displayed a good larvicidal activity in presence of different factors related with Ae.aegypti breeding sites,and had low citotoxicity against macrophages.These results can contribute to the improvement of existing biological control strategies and the development of new biolarvicides. | Aileen Gonzalez Rizo Camilo E Castañet Martinez Celeste Ramírez Cardentey Ariamys Companioni Ibañez Zulema Menéndez Díaz Lianet Monzote Fidalgo Hilda M HernandezÁlvarez | 2022 | Asian Pacific Journal of Tropical Medicine2022，15，2： | 0 |
| 12 | What is the optimal level of vitamin D in non-dialysis chronic kidney disease population?显示文摘AIM To evaluate thresholds for serum 25(OH)D concentrations in relation to death, kidney progression and hospitalization in non-dialysis chronic kidney disease(CKD) population.METHODS Four hundred and seventy non-dialysis 3-5 stage CKD patients participating in OSERCE-2 study, a prospective, multicenter, cohort study, were prospectively evaluated and categorized into 3 groups according to 25(OH)D levels at enrollment(less than 20 ng/mL, between 20 and 29 ng/mL, and at or above 30 ng/mL), considering 25(OH)D between 20 and 29 ng/mL as reference group. Association between 25(OH)D levels and death(primary outcome), and time to first hospitalization and renal progression(secondary outcomes) over a 3-year followup, were assessed by Kaplan-Meier survival curves and Cox-proportional hazard models. To identify 25(OH)D levels at highest risk for outcomes, receiver operating characteristic(ROC) curves were performed.RESULTS Over 29 ± 12 mo of follow-up, 46(10%) patients dead, 156(33%) showed kidney progression, and 126(27%) were hospitalized. After multivariate adjustment, 25(OH)D < 20 ng/mL was an independent predictor of all-cause mortality(HR = 2.33; 95%CI: 1.10-4.91; P = 0.027) and kidney progression(HR = 2.46; 95%CI: 1.63-3.71; P < 0.001), whereas the group with 25(OH)D at or above 30 ng/mL did not have a different hazard for outcomes from the reference group. Hospitalization outcomes were predicted by 25(OH) levels(HR = 0.98; 95%CI: 0.96-1.00; P = 0.027) in the unadjusted Cox proportional hazards model, but not after multivariate adjusting. ROC curves identified 25(OH)D levels at highest risk for death, kidney progression, and hospitalization, at 17.4 ng/mL [area under the curve(AUC) = 0.60; 95%CI: 0.685-0.69; P = 0.027], 18.6 ng/mL(AUC = 0.65; 95%CI: 0.60-0.71; P < 0.001), and 19.0 ng/m L(AUC = 0.56; 95%CI: 0.50-0.62; P = 0.048), respectively.CONCLUSION25(OH)D < 20 ng/mL was an independent predictor of death and progression in patients with stage 3-5 CKD, with no additional benefits when patients reached the levels at or above 30 ng/m L suggested as optimal by CKD guidelines. | Pablo Molina JoséL Górriz Mariola D Molina Sandra Beltrán Belén Vizcaíno Verónica Escudero Julia Kanter Ana Iávila Jordi Bover Elvira Fernández Javier Nieto Secundino Cigarrán Enrique Gruss Gema Fernández-Juárez Alberto Martínez-Castelao Juan F Navarro-González Ramón Romero Luis M Pallardó | 2016 | World Journal of Nephrology2016，5，5： | 1 |
