[Helicobacter pylori eradication frequency with the conventional triple therapy in adult patients at the Centro Médico Issemym]. / Frecuencia de erradicación del Helicobacter pylori con triple esquema convencional en pacientes adultos del Centro Médico Issemym.

BACKGROUND: In Mexico, the prevalence of Helicobacter pylori (H. pylori) infection is high. The bacterial eradication rate with the administration of antibiotic regimens recommended by international guidelines is not yet clear. AIMS: To determine the eradication frequency of H. pylori infection in the adult Mexican population that underwent treatment with the conventional triple regimen. MATERIAL AND METHODS: A cross-sectional study was carried out that evaluated the effectiveness of the triple regimen in individuals with confirmed infection that received consensual treatment and then underwent tests to corroborate eradication. RESULTS: From a total of 249 potential case records, 26 did not meet the inclusion criteria. Two hundred and twenty-three patients were enrolled for analysis, 64,00% women and 36,00% men, with a mean age of 49,4 years (range 17-86). Comorbidities presented in 55,60% of the patients and 28,60% referred to chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs). Bacterial eradication with the triple regimen was 65,50% (146/223); of the 77 patients with no eradication, 11 received a quadruple regimen as second-line treatment resulting in bacterial eradication in 5/11 (45,45%) patients, for an overall eradication of 67,70%. CONCLUSIONS: The eradication rate in our study population was suboptimal due to the probability of multiple factors that are difficult to identify, given the retrospective design of the study. A prospective and controlled evaluation of the recommended regimens needs to be carried out in order to determine their true effectiveness.

Absorción de grasa proveniente de tres fuentes dietarias en ratas con diarrea inducida con lactosa / Absorption of fat from three dietary sources in rats with lactose induced diarrhea

Low energy intake is one the most important factors related to nutritional wasting during diarrheal episodes and fat is the macronutrient with the highest energy value. So we intended to seek dietary fat sources, with the highest bioavailability during diarrheal episodes. Three basal (control) and three 42.8 lactose containing diets, used to induce diarrhea, were prepared with corn oil, butterfat or lard. The assay included 48 Sprague-Dawley rats, 28 d of age, initial weights of 65.5 +/- 5.2 g, distributed in 6 groups that received the diets during 15 d. The different types of fat did not affect diet intake, weight gain or fecal losses in rats without diarrhea (control). Low weight gain was found in rats with diarrhea regardless of the type of fat consumed and was related to low diet consumption. Mean fat absorption during diarrhea was as follows: butterfat 84, lard 87 and corn oil 91. The latter was related to lower fecal losses and higher fat absorption during the 15 d study. Considering that the three fat sources evaluated are easily purchased and widely accepted, and that nutritional management of subjects with diarrhea includes the intake of energy dense diets, it seems that the use of corn oil in these formulations could offer greater advantages.

[Social security nursing in Costa RICA]. / La enfermería en la seguridad social en Costa Rica.

This article reviews the development of social security in Costa Rica throughout the various stages of its growth starting in 1941, with special reference to the scope of the health and maternity insurance system and to disability, old-age, and life insurance. After describing the institutional setting of the social security system, the authors analyze the changes that have taken place in the training and performance of duties of nursing staff in the health services, all of which are now part of the Costa Rican Social Security Fund. Lastly, they present the two-year curriculum for training the graduate nurse, and refer to the practice of nursing in the social security system and to the duties performed by the nurse in health education, the actual care of the well and the sick, administration, and research.
