RESULTS In modified-ITT (mITT) analysis including 83 Intervention and 41 Usual Care eligible patients, fluid balance at 72 hours or ICU discharge was significantly lower (-1.37L favoring Intervention arm, 0.65 ± 2.85L Intervention arm vs. 2.02 ± 3.44L Usual Care arm, p=0.021. Fewer patients required renal replacement therapy (5.1% vs 17.5%, p=0.04) or mechanical ventilation (17.7% vs 34.1%, p=0.04) in the Intervention arm compared to Usual Care. In the all-randomized Intent to Treat (ITT) population (102 Intervention, 48 Usual Care) there were no significant differences in safety signals. INTERPRETATION Physiologically informed fluid and vasopressor resuscitation using passive leg raise-induced stroke volume change to guide management of septic shock is safe and demonstrated lower net fluid balance and reductions in the risk of renal and respiratory failure. Dynamic assessments to guide fluid administration may improve outcomes for septic shock patients compared with Usual Care. BACKGROUND Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality. We hypothesized that applying machine learning to clinical and quantitative CT imaging features would improve mortality prediction in COPD. METHODS We selected 30 clinical, spirometric, and imaging features as inputs for a random survival forest (RSF). We used top features in a Cox regression to create a machine learning mortality prediction (MLMP-COPD) model, and also assessed the performance of other statistical and machine learning models. We trained the models in moderate-to-severe COPD subjects from a subset of COPDGene, and tested prediction performance in the remainder of individuals with moderate-to-severe COPD in COPDGene and ECLIPSE. We compared our model to BODE; BODE modifications; and the age, dyspnea, obstruction (ADO) index. RESULTS We included 2,632 COPDGene and 1,268 ECLIPSE participants. The top predictors of mortality were 6-minute walk distance, FEV1 (% predicted) and age. The top imaging predictor was pulmonary artery-to-aorta ratio. MLMP-COPD resulted in a C-index of ≥ 0.7 in both COPDGene and ECLIPSE (6.4- and 7.2-year median follow up, respectively), significantly better than all tested mortality indices (p-value less then 0.05). MLMP-COPD had fewer predictors, but similar performance to other models. The group with the highest BODE scores (7-10) had 64% mortality, while the highest mortality group defined by MLMP-COPD had 77% mortality (p = 0.012). CONCLUSIONS A MLMP-COPD model outperformed 4 existing models for predicting all-cause mortality across two COPD cohorts. Performance of machine learning was similar to traditional statistical methods. The model is available online at https//cdnm.shinyapps.io/cgmortalityapp/. Various putative oxygen chemosensory cells are reported to be present throughout the vertebrate body performing pivotal roles in respiration by initiating responses during acute hypoxia. Since air-breathing fishes often are exposed to the oxygen-deficient milieu, in such conditions various chemosensory cells operate in an orchestrated fashion. The Pseudobranchial neurosecretory system (PSNS) a newly discovered system, is one of these. KC7F2 in vitro It has been placed in the category of "Diffuse NE systems (DNES)". It is found in all the catfish species and in some other non-catfish group of teleosts. In catfishes, it is present in close association with the carotid labyrinth- a chemosensory structure, known in fish and amphibians. The presence of this system in Glossogobius giuris, in association with the pseudobranch, a structure considered to be precursor of carotid labyrinth, is a significant finding. In an attempt to study the structure and organization of the pseudobranchial neurosecretory system in a non-catfish species of teleost, the present investigation was undertaken on a goby G. giuris. The histological observations, using a neurosecretion-specific stain, revealed the presence of this system in G. giuris. The findings are discussed in the light of the association of PSNS with pseudobranch and the type of "neurohaemal contact complex" formed between this neurosecretory system and the elements of the circulatory system. BACKGROUND Campylobacter is the most common cause of infectious diarrhea in agammaglobulinemia patients. These infections can be severe, prolonged, and recurrent in such patients. PATIENT AND METHODS We report a 29-year-old male patient with X-linked agammaglobulinemia with Campylobacter coli enterocolitis that persisted for nine months despite multiple 10- to 14-day courses of oral ciprofloxacin and azithromycin. RESULTS The isolate was highly resistant to ciprofloxacin, erythromycin, tetracycline, and fosfomycin. The patient failed to respond to intravenous ertapenem, 1.0g/day for two weeks, to which the pathogen was susceptible. He was finally cured with oral gentamicin, 80mg four times daily, and stool cultures remained negative during the seven-month follow-up. CONCLUSION Oral aminoglycoside might be the most appropriate choice for eradication of persistent Campylobacter in the intestinal tract for macrolide- and fluoroquinolone-resistant isolate in agammaglobulinemia patients with chronic diarrhea or relapsing systemic infections. Endothelial dysfunction (ED) is a critical and initiating factor in the genesis of diabetic vascular complications whose occurrence and development is closely related to the complex intravascular microenvironment. However, currently, there is no dynamic model simulating the diabetic vascular endothelial microenvironment that can be used to investigate the mechanism underlying multifactor-induced ED. Here, we developed an integrated microfluidic chip as a new methodological platform to study vascular ED. Selenoprotein S (SELENOS) was found to be involved in the defense against oxidative stress-induced vascular endothelial injury in our previous studies. However, the regulatory signaling pathway underlying this process has not been described. With this chip, we demonstrated that multifactor-induced oxidative stress injury in human aortic endothelial cells (HAECs) has a synergistic effects and upregulates SELENOS expression. Subsequently, SELENOS was found to protect HAECs against multifactor-induced oxidative stress injury by regulating the PKCα/PI3K/Akt/eNOS pathway in the diabetic vascular endothelial microenvironment.
