Optimal length of triple therapy for H pylori eradication in a population with high prevalence of infection in Chile

引用

World Journal of Gastroenterology 2007年第21期13卷 2967-2972页

作者： Arnoldo Riquelme Alejandro Soza Cesar Pedreros Andrea Bustamante Felipe Valenzuela Francisco Otarola eduardo Abbott Marco Arellano Brenda medina Alejandro Pattillo Douglas Greig Marco Arrese Antonio Rollan Department of Gastroenterology Pontificia Universidad Católica de Chile Hospital de Urgencia Asistencia Pública SantiagoChile Department of Internal Medicine Pontificia Universidad Católica de Chile

AIM:To compare the efficacy of 7-d versus 14-d triple therapy for the treatment of H pylori infection in Chile,with a prevalence of 73% in general population. METHODS:H pylori-infected patients diagnosed by rapid urease test,with non-ulcer dyspepsia or peptic ulcer disease were randomized to receive omeprazole 20 mg bid,amoxicillin 1 g bid,and clarithromycin 500 mg bid for 7 (OAC7) or 14 (OAC14) d. Primary outcome was eradication rate 6 wk after the treatment. Subgroup analysis was carried out considering the eradication rate among patients with or without peptic ulcer disease and eradication rate among smokers or non-smokers. RESULTS:One hundred and thirty-one patients were randomized to OAC7 (n = 69) or OAC14 (n = 62). The overall eradication rate (intention-to-treat) was 78.3% in OAC7 and 85.5% in OAC14 groups,without a significant difference (P =0.37). No significant difference in the eradication rate was found among the patients with peptic ulcer disease (n = 31) between the OAC7 group (85.7%) and OAC14 group (87.5%). However,smokers had an obviously lower eradication rate compared to non-smokers,particularly in the OAC7 group (57.1% in smokers vs 83.6% in non-smokers; P = 0.06). Adverse effects rate were similar between both groups. CONCLUSION:Short-term efficacy of triple therapy with OAC for 7 d is comparable to 14 d in this high-prevalence population. Longer follow-up,and studies focused to some subgroups of patients (smokers and non-ulcerpatients) are necessary to support widespread use of 7-d instead of 10-14-d triple therapy in a developing country like Chile.

Lumbar-Sacral Plexus Block Anesthesia versus General Anesthesia for Total Hip Arthroplasty: Case Control Study

引用

Open Journal of Anesthesiology 2021年第9期11卷 259-268页

Background: Peripheral block techniques for total hip arthroplasty have been used as an analgesic strategy, only a few studies described it as an anesthetic technique, so the perioperative performance and safety are poorly studied. Methods: 78 total hip arthroplasties were prospectively observed in our hospital. Divided into 2 groups: 1) General anesthesia;and 2) Lumbar sacral plexus block anesthesia. Variables measured in both groups were: demographics, conversion to general anesthesia, total opioid doses, surgical time, blood loss, postoperative pain, use and total dose of vasopressors drugs, transfusion and ICU transfer needs, postoperative ambulation time, and length of hospital stay. T student and chi-square tests were used upon the case. A significant difference was considered when a value of p Results: 3 patients (7.3%) anesthetized with combined lumbar sacral plexus block were converted to general anesthesia. When comparing peripheral nerve block and general anesthesia, less intraoperative (p = 0.000) and postoperative (p = 0.002) opioid consumption were noted, less postoperative pain in PACU (p = 0.002) and in the first 24 hours (p = 0.005), as well as earlier onset of ambulation (p = 0.008) and shorter hospital stay (p = 0.031). Conclusions: In our study, the lumbar and sacral plexus block anesthesia technique provided anesthetic conditions to perform hip joint arthroplasty and it was proved to be advantageous in comparison to general anesthesia.

Effect of a bacterial inoculum and additive on dry matter in situ degradability of sugarcane silage

引用

Journal of Integrative Agriculture 2015年第3期14卷 497-502页

作者： José A Reyes-Gutiérrez Oziel D Montaez-Valdez Ramón Rodríguez-Macias Mario Ruíz-López eduardo Salcedo-Pérez Cándido E Guerra-medina South University Center University of Guadalajara University Center for Biological and Agricultural Science University of Guadalajara South Coast University Center University of Guadalajara

The objective of this study was to evaluate the effect of adding a bacterial inoculum and a handmade additive to sugarcane silage（SCS） on the in situ digestibility of dry matter（DM）. The treatments were： T1） sugarcane silage（SCS） and T2） sugarcane silage with 1% inoculum and 1% additive（SCS＋）. The bacterial inoculum consisted of 10.0% molasses, 1.0% yogurt, 5.0% chicken manure, 0.5% urea, and 83.0% water, and the additive was formulated with 1.0% urea, 0.1% ammonium sulfate, and 0.25% phosphorus. In situ dry matter digestibility（DMD） was determined using the nylon bag technique with four cows equipped with ruminal fistulas. Cows were fed with ensiled sugarcane supplemented with 1 kg of commercial concentrate. 5 g of ground sample for each sugarcane treatment were weighted in nylon bags and incubated for 4, 8, 12, 24, 48, and 72 h in a completely randomized design with six replicates. The DMD（%） was higher（P〈0.05） for SCS＋ for all incubation times when compared with SCS. There were no differences in ruminal p H between the treatments for all the incubation times. The data suggested that the sugarcane silage with bacterial inoculum and additive could be an alternative for providing forage for ruminants during the season of low growth and quality grass.

Analysis of the Per Capita Generation of Municipal Solid Waste by Socioeconomic Strata in Veracruz, Mexico, Using a Statistical Experimental Design

引用

Journal of Chemistry and Chemical Engineering 2012年第2期6卷 138-146页

作者： Lorena de medina-Salas eduardo CastiUo-Gonzalez Rabindranarth Romero-Lopez Luis Omar Jamed-Boza Chemical Engineering School University Veracruzana Xalapa 91040 Veracruz Mexico Civil Engineering School University Veracruzana Xalapa 91040 Veracruz Mexico

The management of municipal solid waste （MSW） is currently one of the major environmental concerns in Mexico. Therefore, municipalities must develop local programs for prevention and integrated management of MSW based on the data of MSW generation; however, these are scarce and diffuse. It is known that the MSW generation is affected by many factors, including life level. Given the importance of having reliable data, the objective of this study was to determine the per capita MSW generation of a small urban locality in the state of Veracruz and test whether there were significant statistic differences of per capita M SW generation among the life levels. The households were randomly sampled according to the Mexican standard of reference and were classified as popular, middle and residential. The per capita MSW generation determined was 0.355 kg·inhab^-***^-1. This value was lower than the value estimated by the national reference, suggesting that it might be overestimated and consequently lead to errors in estimating installations costs for the MSW treatment. The result of the experimental design revealed that there were significant statistic differences in the per capita MSW generation among the three socioeconomic strata. This study will allow the municipality to establish better strategies within the municipal program and differential rate for the provision of public clean service and it also provides a solid basis for future research under similar conditions.
