The medicinal plant Panax notoginseng is considered a promising source of secondary metabolites due to its saponins. However, there are relatively few studies on the response of saponins to nitrogen (N) availability and the mechanisms underlying the N-driven regulation of saponins. Saponins content and saponins -related genes were analyzed in roots of P. notoginseng grown under low N (LN), moderate N (MN) and high N (HN). Saponins was obviously increased in LN individuals with a reduction in β-glucosidase activity. LN facilitated root architecture and N uptake rate. Compared with the LN individuals, 2872 and 1122 genes were incorporated into as differently expressed genes (DEGs) in the MN and HN individuals. Clustering and enrichment showed that DEGs related to "carbohydrate biosynthesis", "plant hormone signal transduction", "terpenoid backbone biosynthesis", "sesquiterpenoid and triterpenoid biosynthesis" were enriched. The up-regulation of some saponins-related genes and microelement transporters was found in LN plants. Whereas the expression of IPT3, AHK4 and GS2 in LN plants fell far short of that in HN ones. Anyways, LN-induced accumulation of C-based metabolites as saponins might derive from the interaction between N and phytohormones in processing of N acquisition, and HN-induced reduction of saponins might be result from an increase in the form of β-glucosidase activity and N-dependent cytokinins (CKs) biosynthesis.OBJECTIVE To investigate the association between chronic obstructive pulmonary disease (COPD) and smoking with outcome in patients with COVID-19.METHODS A systematic literature search was performed using PubMed, EuropePMC, SCOPUS and the Cochrane Central Database. A composite of poor outcome, mortality, severe COVID-19, the need for treatment in an intensive care unit (ICU) and disease progression were the outcomes of interest.RESULTS Data on 4603 patients were pooled from 21 studies. COPD was associated with an increased risk for composite poor outcome (OR 5.01, 95%CI 3.06-8.22; P less then 0.001; I² 0%), mortality (OR 4.36, 95%CI 1.45-13.10; P = 0.009; I² 0%), severe COVID-19 (OR 4.62, 95%CI 2.49-8.56; P less then 0.001; I² 0%), ICU care (OR 8.33, 95%CI 1.27-54.56; P = 0.03; I² 0%), and disease progression (OR 8.42, 95%CI 1.60-44.27; P = 0.01; I² 0%). Smoking was found to increase the risk of composite poor outcome (OR 1.52, 95%CI 1.16-2.00; P = 0.005; I² 12%), and subgroup analysis showed that smoking was significant for increased risk of severe COVID-19 (OR 1.65, 95%CI 1.17-2.34; P = 0.004; I² 11%). Current smokers were at higher risk of composite poor outcomes (OR 1.58, 95%CI 1.10-2.27; P = 0.01; I² 0%) than former/non-smokers.CONCLUSION Our systematic review and meta-analysis revealed that COPD and smoking were associated with poor outcomes in patients with COVID-19.
Alcohol use disorder (AUD) is a chronic and relapsing condition for which current pharmacological treatments are only modestly effective. The development of efficacious medications for AUD remains a high research priority with recent emphasis on identifying novel molecular targets for AUD treatment and to efficiently screen new compounds aimed at those targets. Ibudilast, a phosphodiesterase inhibitor, has been advanced as a novel addiction pharmacotherapy that targets neurotrophin signaling and neuroimmune function.

This study will conduct a 12-week, double-blind, placebo controlled randomized clinical trial of ibudilast (50 mg BID) for AUD treatment. We will randomize 132 treatment-seeking men and women with current AUD. We will collect a number of alcohol consumption outcomes. #link# Tolinapant among these is percent heavy drinking days (PHDD); secondary drinking outcomes include drinks per day, drinks per drinking day, percent days abstinent, percent subjects with no heavy drinking days, and percent subjects abe Treatment of Alcohol Use Disorder".

In December 2016, three cases of serogroup B invasive meningococcal disease, including two children from the same middle school (11 to 15 years old pupils), occurred in the department (administrative district) Côtes-d'Armor (Brittany, France). They were infected by a rare strain (BP1.7-2,4F5-9cc162), covered by the 4CMenB vaccine (Bexsero®). Four months later, two cases due to the same strain occurred in a high school in the same area (15 to 19 years old students). In accordance with French recommendations, vaccination was proposed to students of both schools and to all individuals aged 11-19 years living or studying in the hyperendemic area. We describe these vaccination campaigns, from the alert to the impact evaluation.

The target population included 8884 people 579 in the middle school, 2007 in the high school and 6298 in the community. In both schools, vaccination sessions were organized directly on site. In the community, teenagers were vaccinated by general practitioners. The vaccination campaign tthe end of the campaigns in the area.
Do children have an increased risk for brain arteriovenous malformation (AVM) recurrence compared with adults and does this risk vary depending on initial presentation with AVM rupture?

We retrospectively studied 115 patients initially presenting with brain AVM under age 25 years who underwent complete surgical resection of the AVM as documented by digital subtraction angiography (DSA) and had delayed follow-up DSA to evaluate for AVM recurrence after apparent initial cure.

The mean time from baseline DSA to follow-up DSA was 2.3 years, ranging from 0 to 15 years. Twelve patients (10.4% of the 115 patient cohort and 16.7% of 72 patients with hemorrhage at initial presentation) demonstrated AVM recurrence on follow-up DSA. All patients with recurrence initially presented with intracranial hemorrhage, and intracranial hemorrhage was a significant predictor of recurrence (log rank
=0.037). Among patients with initial hemorrhage, the 5-year recurrence rate was 17.8% (95% CI, 8.3%-35.7%). All recurrences occurred in patients who were children at the time of their initial presentation; the oldest was 15 years of age at the time of initial AVM surgery. The 5-year recurrence rate for children (0-18 years of age) with an initial presentation of hemorrhage was 21.4% (95% CI, 10.1%-41.9%). Using Cox regression, we found the risk of AVM recurrence decreased by 14% per each year increase in age at the time of initial surgical resection (hazard ratio=0.86 [95% CI, 0.75-0.99];
=0.031).

There is a high rate of recurrence of apparently cured brain AVMs in children who initially present with AVM rupture. Imaging follow-up is warranted to prevent re-rupture.
