As infec??es relacionadas ? assist?ncia ? sa?de (IRAS) s?o atualmente um dos principais problemas de sa?de p?blica. Os estafilococos coagulase-negativa (ECN) est?o entre as esp?cies mais prevalentes neste tipo de infec??o, devido ? sua capacidade de colonizar dispositivos m?dicos invasivos. A clorexidina ? extensivamente utilizada no ambiente hospitalar como forma de preven??o e controle de IRAS. No entanto, a literatura relata a exist?ncia de cepas com susceptibilidade reduzida ocasionada possivelmente pela presen?a dos genes qacA/B. O objetivo do estudo foi investigar a susceptibilidade ? clorexidina e sua rela??o com a presen?a dos genes qacA/B em 211 isolados de ECN provenientes de diferentes hospitais da cidade do Natal-RN. As amostras foram identificadas por testes bioqu?micos convencionais; a susceptibilidade ? antimicrobianos foi realizada pela metodologia disco-difus?o; a determina??o da Concentra??o Inibit?ria M?nima (CIM) para a clorexidina foi avaliada pela t?cnica de dilui??o em ?gar; a t?cnica da PCR foi utilizada para pesquisar os genes qacA/B e o gene mecA. No total de 211 amostras de ECN, 69% foram isolados a partir hemoculturas. As esp?cies mais frequentes foram S. epidermidis, S. hominis hominis, S. auricularis e S. haemolyticus, respectivamente. As cepas apresentaram um perfil de resist?ncia a multidrogas de 87%, incluindo resist?ncia ? oxacilina; 31% demonstraram susceptibilidade reduzida ? clorexidina. Os genes qacA/B foram detectados tanto em amostras resistentes ? clorexidina (32/32) quanto em amostras suscept?veis (17/32). Grande parte das cepas com susceptibilidade reduzida ? clorexidina exibiram tamb?m multirresist?ncia aos antibi?ticos testados (94%). A identifica??o de cepas com susceptibilidade reduzida ? clorexidina nesse estudo representa uma amea?a as pr?ticas de controle de IRAS. Apesar de todas as cepas resistentes ? clorexidina possu?rem os genes qacA/B, sua presen?a n?o foi um fator determinante para a express?o da resist?ncia, necessitando de estudos adicionais. A diminui??o da susceptibilidade ? antiss?pticos pode levar ? persist?ncia bact?rias no ambiente hospitalar contribuindo, dessa forma, para a sobreviv?ncia de cepas multirresistentes.
Health Care Associated Infections (HAI) are currently a of major public health problem. The coagulase-negative Staphylococci (CNS) are among the most prevalent species in this type of infection due to their ability to colonize invasive medical devices. Chlorhexidine is extensively used in the hospital setting as a means of prevention and control of HAI. However, the existence of strains with reduced susceptibility caused possibly by the presence of the qacA/B genes has been reported in the literature. The main of this study was to investigate the susceptibility to chlorhexidine and its relation to the presence of the qacA/B genes in 211 isolates of ECN from diferente hospitals in the city of Natal-RN. Samples were identified by standard biochemical tests; the susceptibility to antimicrobials was performed using the disc-diffusion methodology; the susceptibility to chlorhexidine was evaluated by determining the Minimum Inhibitory Concentration (MIC) by the agar dilution technique; the PCR method was used to investigate the qacA/B genes and mecA gene. In total of 211 CNS samples, 69% were isolated from blood cultures. The most frequent species were S. epidermidis, S. hominis hominis, S. auricularis and S. haemolyticus, respectively. The strains had a multidrug resistance profile of 87%, including resistance to oxacillin; 31% demonstrated reduced susceptibility to chlorhexidine. The qacA/B genes were detected in both chlorhexidine resistant (32/32) and susceptible samples (17/32). Most of the strains with reduced susceptibility to chlorhexidine also showed multidrug resistance to the tested antibiotics (94%). Identification of strains with reduced susceptibility to chlorhexidine in this study poses a threat to HAIs control practices. Although all strains resistant to chlorhexidine had the qacA/B genes, their presence was not a determining factor for the expression of the resistance, requiring additional studies. The decrease in susceptibility to antiseptics may allow bacteria to persist in the hospital environment, thus contributing to the survival of multiresistant strains.

Texto completoThe increased development of microorganisms capable of resisting the most common antimicrobial substances, in recent years, is a phenomenon that has long been of concern to various global health organizations. The development of resistance to adverse substances is a natural mechanism, which microorganisms have exploited since ancient times. With the onset of industrialization in the early 20th century and the discovery of powerful antibiotic drugs, mankind has been able to significantly improve its lifestyle. The result of decades of irresponsible use and wastage of these antimicrobial substances in the environment, however, has inevitably led to the generation of antibiotic-resistant microorganisms. Humanity, if it wants to better contain this phenomenon, in the future will have to act with more conscience, limiting waste, using products that better preserve the environment and developing new effective antimicrobial substances. In this Ph.D. work we describe the synthesis of novel antimicrobial quaternary ammonium salts (QACs) by exploiting the high reactivity of chloro triazines. Several triazine QACs were synthesized and their antimicrobial activity was investigated. In the first instance, we focused on the synthesis of a library of morpholino-triazine QACs directly inspired by the structure of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride or DMTMM. Then evaluating its efficacy against Gram-positive and Gram-negative bacterial strains such as Staphylococcus aureus and Escherichia coli. Next, we moved on to the synthesis of a library of imidazole-triazine QACs that showed superior performance compared to the first morpholino-triazine QACs, both in terms of yield and antimicrobial activity. Finally, the synthesis of various blockcopolymers based on 2-N-morpholinoethyl methylmethacrylate (MEMA) and their use in the preparation of polymeric QACs and antimicrobial surfaces was described.

Texto completoThe "Questionnaire for Assessing the Childbirth Experience (QACE)" seeks to detect those women who have had a negative experience in childbirth and avoid having repercussions in subsequent pregnancies or in their relationship. The objective of the thesis is to obtain, adapt and validate the QACE from English to the Spanish version of Spain, as well as to describe the obstetrical results and the birth satisfaction level between the participant hospitals. This study concludes in three main results: a) CEEP has been adapted and translated in a methodologically correct manner, internal consistency was assured (ω=0,818) and is stable over time (ICC 0.94, p <.00); b) confirmatory factor analysis was good/adequate with 20 items classified in four factors that explained 52.63% of the variance; c)in terms of birth satisfaction, similar results were obtained in both hospitals. However, there are better obstretrical outcomes in the hospital with less complexity.

Texto completoIn the present work, a business plan for facial masks based on clays and agar agar was executed, created by five students from the Business School of the Peruvian University of Applied Sciences (UPC). The project was developed based on the need for women to find cosmetic products with natural ingredients that do not contain chemicals that can damage their skin and that are friendly to the environment. When analysing the beauty market, we could see that the growth of this sector is constant and the trend to consume natural beauty products is growing. After evaluating the needs of our target audience, we developed the formulas for the three versions of masks, using natural inputs that fulfil different functions such as purifying, regenerating and deeply cleansing the skin. The objective of this project is to be able to commercialize them. At the end of our sales project, the different budget plans for the HR, operations, marketing and Corporate Social Responsibility areas will be analysed to have a projection of what we need to carry out our business idea. In addition, to better examine our model, the total project was evaluated to see if it would generate value and if it is profitable. With this, we will be able to know if it is acceptable to invest in it or in any case, learn and create new business ideas. Therefore, the objectives set out in this project have been fully achieved, as well as the data found facilitated their achievement.
