75 (95% confidence interval 0.65-0.81), which is comparable with the area under the curve of the derivation cohort (0.77). The GSDCS score differentiated between low- (0-1.3), medium- (1.4-2.3) and high-risk (2.4-4.3) patients for RGNB infection (P<0.001) in a UK setting.

A simple bedside clinical prediction tool may be used to identify and differentiate patients at low, medium and high risk of RGNB infection prior to initiation of prompt empirical antimicrobial therapy in the intensive care setting.

Indeed it depends on a balanced combination of metal ion reactivity towards proteins and nucleic acids. Here we analysed the effect of two trans-platinum planar amines in comparison to cisplatin and transplatin on the DNA processivity by human topoisomerases I and IIα. Each tested metal complex produces DNA adducts with unique geometrical features and, consistently, they exert different effects on the activity of tested enzymes. Opaganib nmr Moreover, our results highlighted more subtle consequences on the enzymatic activity by the tested metal complexes which derive from a combination of preferential DNA or protein platination. Moreover, we observed that it is not possible to predict the overall output based only on the cis- vs trans- geometry of the tested metal complexes. This variable behaviour reflects the chemical reactivity profile of each single metal complex and can be usefully addressed to describe their different properties in the complex physiological environment.This study focused on particulate matter (PM2.5) and carbon species in Seoul, South Korea, to quantitatively evaluate their long-term trends and assess the main correlating factors. Ambient PM2.5 samples were collected over a 24 h period every third or sixth day from March 2003 to December 2017. The mean concentrations of PM2.5, organic carbon (OC), elemental carbon (EC), primary and secondary OC (POC and SOC) in Seoul over 15 years were 32.2 μg/m3 and 7.28 μg/m3, 1.85 μg/m3, 4.29 μg/m3 and 3.54 μg/m3 respectively. The long-term concentration trends in PM2.5, OC, EC, POC, and SOC decreased significantly at rates of -2.09, -3.13, -6.31, -2.86, and -3.88 per year, respectively from 2003 to 2017 (p less then 0.001), whereas the long-term trends in OC/EC significantly increased at a rate of 12.9/year (p less then 0.001). These long-term decreases in PM2.5 and carbon species concentrations were most pronounced in 2008 but almost disappeared from 2013 onwards. Considering the decrease in wind speed and variations in the concentration of gaseous air pollutants (carbon monoxide, sulfur dioxide, nitrogen dioxide, and volatile organic compounds) without a tendency to increase or decrease since 2013, secondary aerosol formation by atmospheric stagnation alleviated long-term decreases in PM2.5 and carbon species concentrations. The long-term decreases in EC concentration were the most consistent and rapid, strongly suggesting that atmospheric policies related to mobile in South Korea were effective in reducing EC concentration. Future air quality management should focus on the secondary formation of air pollutants based on regional trends in air pollutant concentrations.

Serum polychlorinated biphenyls (PCBs) have been associated with some chronic diseases, but little evidence exists on their possible relationship with neurodegenerative diseases. We aimed to assess the relationship between PCB exposure and the occurrence of dementia and Parkinson disease in a prospective cohort study in a highly polluted area (Brescia-Caffaro).

PCB exposure was assessed by measuring serum levels of 24 congeners. Data on the onset of dementia and Parkinson disease were retrieved by the Brescia Health Protection Agency Database. We used Poisson regression models adjusted for possible confounders to calculate rate ratios (RRs). A mediation analysis was performed to evaluate the mediatory role of cardiovascular diseases.

699 subjects without neurologic diseases at baseline were enrolled (48.1% males, 63.2 years of mean age) in 2001-2013 and followed up to 2018. During a mean follow-up of 8.8 years, 36 and 20 subjects developed dementia and Parkinson disease. Subjects in the 2nd and 3rd tertiles of the total PCBs distribution, compared with those in the 1st tertile, had a higher risk of dementia (RR=2.30 and RR=4.35). The estimates for Parkinson disease included the null value with wide confidence intervals. In the mediation analysis, the association between PCB exposure and dementia was dominated by the direct pathway and not by the hypertension-mediated pathway.

We observed a positive association between total PCBs serum levels and the onset of dementia not mediated by hypertension. For Parkinson, the unstable risk estimates did not allow to draw a conclusion on a possible association.

Dravet syndrome is an infantile epilepsy syndrome with drug resistant seizures and cognitive impairment. The aim of this meta-analysis was to summarize the findings of relevant published studies to identify the efficacy of a ketogenic diet in patients with Dravet syndrome and their compliance thereof, and to provide useful information for clinical practice.

The PubMed, Embase, Wanfang, and CNKI databases were searched for relevant studies published up to September 25, 2019; the included studies were reviewed. Meta-analyses were performed using R software to determine the combined efficacy rates and retention rate for the ketogenic diet in patients with Dravet syndrome.

Seven studies involving 167 patients met the inclusion criteria four were retrospective studies, and three were prospective studies. The meta-analysis revealed that 63 %, 60 %, and 47 % of responder patients achieved ≥50 % seizure reduction at month 3, 6, and 12, respectively. The pooled retention rate of the ketogenic diet at month 6 and month 12 was 78 % and 49 %, respectively.
