Treatment of advanced laryngeal cancer and quality of life. Systematic review.

Introduction And Objectives: The objective was the comparison of the quality of life in patients with advanced laryngeal cancer treated with organ preservation versus surgical treatment.

Methods: We performed a systematic review in the databases MedLine, EMBASE, and PubMed (2014 1991) and Web of Science (2012 - 2014). The search terms were: Laryngeal cancer, organ preservation, chemotherapy, laryngectomy, treatment outcomes and quality of life.

[Methodological guideline for the efficacy and safety assessment of new pharmaceuticals: implementation of EUnetHTA's recommendations].

The European network for Health Technology Assessment (EUnetHTA) is the network of public health technology assessment (HTA) agencies and entities from across the EU. In this context, the HTA Core Model, has been developed. The Andalusian Agency for Health Technology Assessment (AETSA) is a member of the Spanish HTA Network and EUnetHTA collaboration In addition, AETSA participates in the new EUnetHTA Joint Action 3 (JA, 2016-2019).

Interplay between iron homeostasis and the osmotic stress response in the halophilic bacterium Chromohalobacter salexigens.

In this study, the connection between iron homeostasis and the osmostress response in the halophile Chromohalobacter salexigens was investigated. A decrease in the requirement for both iron and histidine and a lower level of siderophore synthesis were observed at high salinity, and these findings were correlated with a lower protein content in salt-stressed cells. A six-gene operon (cfuABC-fur-hisI-orf6 operon) located downstream of the ectABC ectoine synthesis genes was characterized.

[Quality of the pharmacotherapeutic recommendations for the integrated care procedures in Andalusia].

Objectives: To evaluate the quality of the pharmacotherapeutic recommendations included in the Integrated Care Procedures (PAIs regarding its initials in Spanish) of the Andalusian Ministry of Health, published up to March 2008, through the design and validation of a tool.

Methods: The assessment tool was designed based on similar instruments, specifically the AGREE. Other criteria included were taken from various literature sources or were devised by ourselves.

The ectD gene, which is involved in the synthesis of the compatible solute hydroxyectoine, is essential for thermoprotection of the halophilic bacterium Chromohalobacter salexigens.

The halophilic bacterium Chromohalobacter salexigens synthesizes and accumulates compatible solutes in response to salt and temperature stress. (13)C-nuclear magnetic resonance analysis of cells grown in minimal medium at the limiting temperature of 45 degrees C revealed the presence of hydroxyectoine, ectoine, glutamate, trehalose (not present in cells grown at 37 degrees C), and the ectoine precursor, Ngamma-acetyldiaminobutyric acid. High-performance liquid chromatography analyses showed that the levels of ectoine and hydroxyectoine were maximal during the stationary phase of growth.

Osmoprotection of Salmonella enterica serovar Typhimurium by Ngamma-acetyldiaminobutyrate, the precursor of the compatible solute ectoine.

N(gamma)-acetyl-2,4-diaminobutyrate (NADA), the precursor of the compatible solute ectoine, was shown to function as an osmoprotectant for the non-halophilic bacterium Salmonella enterica serovar Typhimurium. The addition of NADA-containing extracts of an ectoine synthase mutant of the broad salt-growing halophile Chromohalobacter salexigens DSM 3043(T) could alleviate the inhibitory effects of high salinity in S. enterica, which lacks the ectoine biosynthetic pathway.
