Fecal microbiota of toxigenic clostridioides difficile-associated diarrhea

Producción CientíficaClostridioides difficile infection (CDI) is currently one of the most important causes of infectious diarrhea in developed countries and the main cause in healthcare settings. Here, we characterized the gut microbiota from the feces of 57 patients with diarrhea from nosocomial and community-acquired CDI. We performed an ecological analysis by high-throughput sequencing of the V3-V4 region of 16S rRNA amplicons and evaluated the association of the various ecological profiles with CDI risk factors. Among all samples Bacteroidaceae 31.01%, Enterobacteriaceae 9.82%, Lachnospiraceae 9.33%, Tannerellaceae 6,16%, and Ruminococcaceae 5.64%, were the most abundant families. A reduced abundance of Bacteroides was associated with a poor CDI prognosis, with severe diarrhea and a high incidence of recurrence. This reduction was associated with a weakened host immune system and previous aggressive antibiotherapy. Peptostreptococcaceae family was 1.56% overall and within the family the only identified member was the genus Clostridioides, positively correlated with the presence of Akkermansia that may be predictive of the presence of a CDI. Finally, a relevant aspect that must be considered in clinical practice is the misdiagnosis of CDI, as patients with a stool sample that tests positive for C. difficile are usually diagnosed with CDI and subsequently treated as such. However, co-infection with other pathogenic agents often plays an important role in the development of diarrhea, and must be considered when prescribing antibiotic treatment.La Gerencia Regional de Salud de la Junta de Castilla y León (Número de subvención GRS 1780 / A / 18).Ministerio de Economía, Industria y Competitividad (beca FPI2014-020

El cambio en la forma en que se establecen las comunicaciones, fundamentalmente entre la población más joven, ha transformado las rutinas de trabajo de los medios de comunicación y de otros sectores íntimamente relacionados con ellos como la publicidad y la comunicación corporativa. La demanda de nuevas habilidades y competencias, además de conocimientos, y la transformación digital que están sufriendo empresas, instituciones y la Administración, al mismo tiempo que la creciente automatización del trabajo, generan muchos interrogantes sobre la posible desaparición y aparición de nuevos puestos de trabajo

Surgical navigation, augmented reality, and 3D printing for hard palate adenoid cystic carcinoma en-bloc resection: case report and literature review

Adenoid Cystic Carcinoma is a rare and aggressive tumor representing less than 1% of head and neck cancers. This malignancy often arises from the minor salivary glands, being the palate its most common location. Surgical en-bloc resection with clear margins is the primary treatment. However, this location presents a limited line of sight and a high risk of injuries, making the surgical procedure challenging. In this context, technologies such as intraoperative navigation can become an effective tool, reducing morbidity and improving the safety and accuracy of the procedure. Although their use is extended in fields such as neurosurgery, their application in maxillofacial surgery has not been widely evidenced. One reason is the need to rigidly fixate a navigation reference to the patient, which often entails an invasive setup. In this work, we studied three alternative and less invasive setups using optical tracking, 3D printing and augmented reality. We evaluated their precision in a patient-specific phantom, obtaining errors below 1 mm. The optimum setup was finally applied in a clinical case, where the navigation software was used to guide the tumor resection. Points were collected along the surgical margins after resection and compared with the real ones identified in the postoperative CT. Distances of less than 2 mm were obtained in 90% of the samples. Moreover, the navigation provided confidence to the surgeons, who could then undertake a less invasive and more conservative approach. The postoperative CT scans showed adequate resection margins and confirmed that the patient is free of disease after two years of follow-up.This work has been supported by projects PI18/01625 (Ministerio de Ciencia, Innovación y Universidades, Instituto de Salud Carlos III and European Regional Development Fund “Una manera de hacer Europa”) and IND2018/TIC-9753 (Comunidad de Madrid)

Evaluation of the interrelated effects of slaughtering, drying, and defatting methods on the composition and properties of black soldier fly (Hermetia illucens) larvae fat

The interrelated effect of different slaughtering, drying and defatting methods of black soldier fly larvae (BSFL) on the lipid composition and properties of the fat was studied. Blanching and freezing were compared as slaughtering methods, oven or freeze-drying as drying methods, and mechanical pressing or supercritical fluid extraction (SFE) as defatting methods. The different modes of slaughtering, drying, and defatting, along with both binary and ternary interactions caused significant effects on processes yields, lipid composition, moisture content and thermal properties. Thus, considering the defatting degree and the yield in total valued products (defatted meal plus fat), the combination of blanching, freeze-drying plus mechanical pressing was the worst option (51.2% and 87.5%, respectively). In contrast, the other combinations demonstrated better and comparable efficiency, although SFE is preferable for defatting (83.2% and 96.9%, respectively). The content of major fatty acids (lauric, palmitic and myristic acids) was significantly affected by the BSFL treatments, although with unsignificant impact on the total saturated fatty acids content. To preserve the integrity of the fat, the combination of blanching and oven-drying was preferred, as non-thermal methods of slaughtering and drying caused intense lipolysis, releasing free fatty acids (FFA) in the range of 18.6–23.5%. To achieve the lowest moisture content in the fats (≤0.1%), oven-drying with mechanical pressing were desired, regardless of the slaughtering method; while values > 1% were reached for freezing, freeze-drying and SFE. Both differences in FFA and moisture contents caused different thermal behaviors in the samples. Specially, the melting temperature was lower for samples with higher FFA and moisture contents, with a notable difference when freezing, freeze-drying and SFE were combined (14.5 ◦C vs 30.6 ◦C, as the mean value for the rest of samples). The different modes of processing did not affect the minor lipid compounds. Therefore, the modes employed for slaughtering, drying, and defatting of BSFL determine, either individually or in combination, the process yields, composition, and properties of the fatThis research was funded by the Spanish National Plans of Aquaculture of the Ministry of Agriculture, Fisheries and Food, project ACUINSECT (Optimization of insect flours as sustainable ingredient for aquaculture feed) with the support of the European Maritime and Fisheries Fund (FEMP

The interaction of slaughtering, drying, and defatting methods differently affects oxidative quality of the fat from black soldier fly (Hermetia illucens) larvae

The interrelation effect of slaughtering, drying, and defatting methods of BSFL on the oxidative quality of the derived fat was studied. Blanching and freezing were compared as slaughtering methods, followed by oven or freeze-drying for drying and mechanical pressing or SFE for defatting. The oxidative state and stability of the extracted fat and defatted meals were monitored immediately after their production, using peroxide value (PV) and Rancimat test, and over 24 weeks of storage. Slaughtering and drying methods had an independent effect on PV, with freezing and freeze-drying being the best methods. Mechanical pressing and SFE were comparable and superior to conventional hexane defatting. Interactions were observed between slaughtering and defatting, drying and defatting, and between all three factors. Generally, freeze-drying combined with any of the slaughtering and defatting methods resulted in the lowest PVs, with mechanical pressing being preferred. Freeze-drying plus mechanical pressing also produced the most stable fats during storage according to the evolution of PV, while the combination of blanching and SFE produced the least stable. A significant correlation was found between the PV at 24 weeks and the antioxidant activity of the fats. Contrary to storage assays, in accelerated Rancimat assays, freeze-dried samples were the least stable, which was partially attributed to the significant correlation with the acid values of the samples. Defatted meals followed a similar pattern to the extracted fat, except for worse oxidation for SFE defatting. Therefore, the different processing methods of slaughtering, drying, and defatting of BSFL differently affect lipid oxidation, with interactions between such successive stepsThis research was funded by the Spanish National Plans of Aquaculture of the Ministry of Agriculture, Fisheries and Food, project ACUINSECT (Optimization of insect flours as sustainable ingredient for aquaculture fee

Enteroaggregative Escherichia coli as etiological agent of endemic diarrhea in Spain: A prospective multicenter prevalence study with molecular characterization of isolates

BackgroundEnteroaggregative Escherichia coli (EAEC) is increasingly associated with domestically acquired diarrheal episodes in high-income countries, particularly among children. However, its specific role in endemic diarrhea in this setting remains under-recognized and information on molecular characteristics of such EAEC strains is limited. We aimed to investigate the occurrence of EAEC in patients with non-travel related diarrhea in Spain and molecularly characterize EAEC strains associated with illness acquired in this high-income setting.MethodsIn a prospective multicenter study, stool samples from diarrheal patients with no history of recent travel abroad (n = 1,769) were collected and processed for detection of EAEC and other diarrheagenic E. coli (DEC) pathotypes by PCR. An additional case–control study was conducted among children ≤5 years old. Whole-genome sequences (WGS) of the resulting EAEC isolates were obtained.ResultsDetection of DEC in the study population. DEC was detected in 23.2% of patients aged from 0 to 102 years, with EAEC being one of the most prevalent pathotypes (7.8%) and found in significantly more patients ≤5 years old (9.8% vs. 3.4%, p < 0.001). Although not statistically significant, EAEC was more frequent in cases than in controls. WGS-derived characterization of EAEC isolates. Sequence type (ST) 34, ST200, ST40, and ST10 were the predominant STs. O126:H27, O111:H21, and O92:H33 were the predominant serogenotypes. Evidence of a known variant of aggregative adherence fimbriae (AAF) was found in 89.2% of isolates, with AAF/V being the most frequent. Ten percent of isolates were additionally classified as presumptive extraintestinal pathogenic E. coli (ExPEC), uropathogenic E. coli (UPEC), or both, and belonged to clonal lineages that could be specifically associated with extraintestinal infections.ConclusionEAEC was the only bacterial enteric pathogen detected in a significant proportion of cases of endemic diarrhea in Spain, especially in children ≤5 years old. In particular, O126:H27-ST200, O111:H21-ST40, and O92:H33-ST34 were the most important subtypes, with all of them infecting both patients and asymptomatic individuals. Apart from this role as an enteric pathogen, a subset of these domestically acquired EAEC strains revealed an additional urinary/systemic pathogenic potential

Prediction of poor outcome in clostridioides difficile infection: A multicentre external validation of the toxin B amplification cycle

Producción CientíficaClassification of patients according to their risk of poor outcomes in Clostridioides difficile infection (CDI) would enable implementation of costly new treatment options in a subset of patients at higher risk of poor outcome. In a previous study, we found that low toxin B amplification cycle thresholds (Ct) were independently associated with poor outcome CDI. Our objective was to perform a multicentre external validation of a PCR-toxin B Ct as a marker of poor outcome CDI. We carried out a multicentre study (14 hospitals) in which the characteristics and outcome of patients with CDI were evaluated. A subanalysis of the results of the amplification curve of real-time PCR gene toxin B (XpertTM C. difficile) was performed. A total of 223 patients were included. The median age was 73.0 years, 50.2% were female, and the median Charlson index was 3.0. The comparison of poor outcome and non–poor outcome CDI episodes revealed, respectively, the following results: median age (years), 77.0 vs 72.0 (p = 0.009); patients from nursing homes, 24.4% vs 10.8% (p = 0.039); median leukocytes (cells/μl), 10,740.0 vs 8795.0 (p = 0.026); and median PCR-toxin B Ct, 23.3 vs 25.4 (p = 0.004). Multivariate analysis showed that a PCR-toxin B Ct cut-off <23.5 was significantly and independently associated with poor outcome CDI (p = 0.002; OR, 3.371; 95%CI, 1.565–7.264). This variable correctly classified 68.5% of patients. The use of this microbiological marker could facilitate early selection of patients who are at higher risk of poor outcome and are more likely to benefit from newer and more costly therapeutic options
