RESUMEN
BACKGROUND/OBJECTIVES: Obstruction of the nasoenteral tube is one of the complications of enteral nutrition therapy, and its causes and frequency of occurrence are not well understood. To evaluate the causes of enteral nutrition feeding tube obstruction. To study the time elapsed between the beginning of the nutrition therapy and the obstruction of the tube. SUBJECTS/METHODS: This was a retrospective cohort study of 1170 patients aged 18 years or older who were hospitalized at Sírio-Libanês Hospital between January 2015 and October 2017, and who were undergoing enteral nutrition therapy delivered using an infusion pump through a nasogastric or nasoenteral tube. The study population included 683 (58%) men and 487 (42%) women. The median age was 79 years. Of these, 1084 patients received enteral nutrition and medication through the feeding tube, and 86 received medication alone. Variables investigated as causes of feeding tube obstruction were the administration of medication through the tube, type of diet, and use of symbiotics. RESULTS: Obstruction rates were 4% for up to 40 days of observation and 8% for the total observation time. The time for obstruction of 10% of the tubes in patients receiving rivaroxaban, linagliptin, metformin, and nystatin was 16, 19, 20, and 28 days, respectively. CONCLUSIONS: The main cause of nasoenteral tube obstruction (odds ratio) was the combination of metformin (2.0), nystatin (3.1), linagliptin (4.3), rivaroxaban (2.4), and a high-protein diet (1.9). Overall, proper tube care and strict compliance with tubal drug delivery guidelines can result in low tube obstruction rates.

During 1993-1994, scientists from developing and developed countries planned and initiated a number of parasite genome projects and several consortiums for the mapping and sequencing of these medium-sized genomes were established, often based on already ongoing scientific collaborations. Financial and other support came from WHO/TDR, Wellcome Trust and other funding agencies. Thus, the genomes of Plasmodium falciparum, Schistosoma mansoni, Trypanosoma cruzi, Leishmania major, Trypanosoma brucei, Brugia malayi and other pathogenic nematodes are now under study. From an initial phase of network formation, mapping efforts and resource building (EST, GSS, phage, cosmid, BAC and YAC library constructions), sequencing was initiated in gene discovery projects but soon also on a small chromosome, and now on a fully fledged genome scale. Proteomics, functional analysis, genetic manipulation and microarray analysis are ongoing to different degrees in the respective genome initiatives, and as the funding for the whole genome sequencing becomes secured, most of the participating laboratories, apart from larger sequencing centres, become oriented to post-genomics. Bioinformatics networks are being expanded, including in developing countries, for data mining, annotation and in-depth analysis.
