BACKGROUND Predictive models within epilepsy are frequently developed via Cox's proportional hazards models. These models estimate risk of a specified event such as 12-month remission. They are relatively simple to produce, have familiar output, and are useful to answer questions about short-term prognosis. However, the Cox model only considers time to first event rather than all seizures after starting treatment for example. This makes assessing change in seizure rates over time difficult. Variants to the Cox model exist enabling recurrent events to be modelled. One such variant is the Prentice, Williams and Peterson - Total Time (PWP-TT) model. An alternative is the negative binomial model for event counts. This study aims to demonstrate the differences between the three approaches, and to consider the benefits of the PWP-TT approach for assessing change in seizure rates over time. METHODS Time to 12-month remission and time to first seizure after randomisation were modelled using the Cox model. Risk of seis useful in determining the longer-term effects of treatment policy. Such a model should be considered when designing future clinical trials in medical conditions typified by recurrent events to improve efficiency and statistical power as well as providing evidence regarding changes in event rates over time.BACKGROUND Videolaryngoscopy (VL) has become a popular method of intubation (ETI). Although VL may facilitate ETI in less-experienced rescuers there are limited data available concerning ETI performed by paramedics during CPR. The goal was to evaluate the impact VL compared with DL on intubation success and glottic view during CPR performed by German paramedics. check details We investigated in an observational prospective study the superiority of VL by paramedics during CPR compared with direct laryngoscopy (DL). METHODS In a single Emergency Medical Service (EMS) in Germany with in total 32 ambulances paramedics underwent an initial instruction from in endotracheal intubation (ETI) with GlideScope® (GVL) during resuscitation. The primary endpoint was good visibility of the glottis (Cormack-Lehane grading 1/2), and the secondary endpoint was successful intubation comparing GVL and DL. RESULTS In total n = 97 patients were included, n = 69 with DL (n = 85 intubation attempts) and n = 28 VL (n = 37 intubation attempts). Videolaryngoscopy resulted in a significantly improved visualization of the larynx compared with DL. In the group using GVL, 82% rated visualization of the glottis as CL 1&2 versus 55% in the DL group (p = 0.02). Despite better visualization of the larynx, there was no statistically significant difference in successful ETI between GVL and DL (GVL 75% vs. DL 68.1%, p = 0.63). CONCLUSIONS We found no difference in Overall and First Pass Success (FPS) between GVL and DL during CPR by German paramedics despite better glottic visualization with GVL. Therefore, we conclude that education in VL should also focus on insertion of the endotracheal tube, considering the different procedures of GVL.

CASE PRESENTATION A 60-year-old female was admitted to our department; endoscopy revealed a smooth protruding lesion in the gastric cardia. The patient was diagnosed with a gastric cardia stromal tumor and the lesion was seen in muscularis propria by endoscopic ultrasonography (EUS). Endoscopic submucosal dissection (ESD) revealed that the lesion was filled with a milky, white liquid and white granulation tissue. Acid-fast specimen staining was negative. Hematoxylin and eosin staining showed patches of caseating necrosis and granulomatous inflammation. Gene sequencing subsequent to polymerase chain reaction (PCR) analysis of the ESD specimen identified Mycobacterium tuberculosis (M. TB) DNA fragments. The patient was put on ATT for 6 months. CONCLUSION Primary isolated gastric TB of the cardia should be suspected in patients without clinical symptoms whose manifestations are similar to those associated with submucosal tumors. TB-PCR may be helpful for further diagnosis.BACKGROUND Common vetch (Vicia sativa L.) is an important self-pollinating annual forage legume and is of interest for drought prone regions as a protein source to feed livestock and human consumption. However, the development and production of common vetch are negatively affected by drought stress. Plants have evolved common or distinct metabolic pathways between the aboveground and underground in response to drought stress. Little is known regarding the coordinated response of aboveground and underground tissues of common vetch to drought stress. RESULTS Our results showed that a total of 30,427 full-length transcripts were identified in 12 samples, with an average length of 2278.89 bp. Global transcriptional profiles of the above 12 samples were then analysed via Illumina-Seq. A total of 3464 and 3062 differentially expressed genes (DEGs) were identified in the leaves and roots, respectively. Gene Ontology (GO) enrichment analyses identified that the dehydrin genes and Δ1-pyrroline-5-carboxylate synthase w coordinated mechanisms of drought response in common vetch, and further provides targets to improve drought resistance through genetic engineering.BACKGROUND Rhizosphere microbiome is dynamic and influenced by environment factors surrounded including pathogen invasion. We studied the effects of Ralstonia solanacearum pathogen abundance on rhizosphere microbiome and metabolome by using high throughput sequencing and GC-MS technology. RESULTS There is significant difference between two rhizosphere bacterial communities of higher or lower pathogen abundance, and this difference of microbiomes was significant even ignoring the existence of pathogen. Higher pathogen abundance decreased the alpha diversity of rhizosphere bacterial community as well as connections in co-occurrence networks. Several bacterial groups such as Bacillus and Chitinophaga were negatively related to the pathogen abundance. The GC-MS analysis revealed significantly different metabolomes in two groups of rhizosphere soils, i.e., the rhizosphere soil of lower harbored more sugars such as fructose, sucrose and melibiose than that in high pathogen abundance. CONCLUSIONS The dissimilar metabolomes in two rhizosphere soils likely explained the difference of bacterial communities with Mantel test.
