There is a significant relationship between the TME score and grade. High TME score samples are highly expressed in immune activation, TGF pathway activation and immune checkpoint genes, and low TME score samples have high frequency mutations of PTEN, CSE1L and ITGB3. Therefore, describing the comprehensive landscape of UCEC's TME characteristics may help explain patients' response to immunotherapy and provide new strategies for cancer treatment.COVID-19 pandemic has become a global concern. Cytokine release syndrome (CRS) complicates acute respiratory distress syndrome (ARDS) and causes multi-organ failure which can subsequently lead to mortality in COVID-19 patients. Tocilizumab, an interleukin-6 antagonist, has shown to salvage patients with cytokine release storm. In this study, we aim to evaluate therapeutic response of Tocilizumab in COVID-19 patients. A single-arm retrospective review of 40 patients with COVID-19, admitted to The Aga Khan University Hospital Karachi, from March 2020 to May 2020 was performed. Selection of patients for use of Tocilizumab was based on severity of disease, rapid clinical deterioration, presence of CRS and absence of any absolute contraindication to Tocilizumab. Improvement after Tocilizumab was defined as improvement in oxygen requirement and inflammatory parameters. Serum levels of inflammatory cytokines like C-reactive protein, ferritin, D-dimer and lactate dehydrogenase levels were monitored before and after administering Tocilizumab. Mean age was 62.4 years and 33 (82.5%) were male. 19 (47.5%) patients were critically sick, 18 (45%) were severely sick and 3 (7.5%) were moderately sick. 29 (77.5%) patients showed significant improvement in oxygen requirement, inflammatory parameters and chest x-rays, out of which 28 patients were discharged home. The mean duration between administration of Tocilizumab and overall improvement was 4.3 ± 3.2 days. Hence, Tocilizumab can be used as a possible treatment option in patients with COVID-19 induced CRS but needs monitoring for its adverse effects.The Quebec residual materials management policy implies the banning of organic waste disposal or incineration from 2022 onwards. This policy also applies to domestic ship-generated organic waste. However, little is known about the current state of ship-generated organic waste management in the province of Quebec. This study aims to analyse the current situation and propose sustainable strategies for ship-generated organic waste valorisation in Quebec. Using the available data, it was attempted to estimate ship-generated waste quantities in Quebec, after which the current practices of domestic ship-generated organic waste management in Quebec and Europe were inventoried, along with international waste management practices. Five waste valorisation scenarios were then proposed and compared in terms of advantages and disadvantages, required equipment, and associated costs and revenues. It involves 1) composting on board of the ship, 2) centralised composting, 3) composting at the port, 4) centralised biomethanation, and 5) biomethanation at the port. The current available data on ship-generated waste quantities in Quebec did, however, not allow selecting an optimal scenario. The information provided in this short communication can serve as a valuable basis to guide future research efforts and decision-making in this regard. AZ191 Furthermore, the current management of international waste was found to be complex and costly, although biomethanation of such waste could offer a suitable and more sustainable solution. Finally, it was concluded that a good cooperation between ships and ports is crucial to the implementation of any sustainable waste valorisation strategy.The occurrence of elevated temperatures within landfills is a challenging issue for landfill operators to detect and correct. Little is known regarding the causes of elevated temperatures (ETs) or the number of landfills currently operating under such conditions. Therefore, the goal of this research was to determine which landfills within Florida have been impacted by ETs, and to develop a more complete understanding of the factors that may lead to these landfills becoming elevated temperature landfills (ETLFs). Historical landfill gas wellhead data, waste deposition reports, and landfill site geometry were collected for 27 landfill cells through the Florida Department of Environmental Protection electronic document management system, OCULUS database and from landfill operators and owners. These data were evaluated to quantify the characteristics that result in landfills having 'elevated' temperatures. Gas data included landfill gas temperatures and methane, carbon dioxide, and balance gas content. Furthermore, landfill maps were created in ArcGIS to observe spatial distribution of ETs in landfills over time. Upon analysis of the landfill gas wellhead data, it was discovered that 74% of studied landfill cells had ET readings; regulatory limits specify a maximum allowable gas temperature of 55 °C (131 °F). It was discovered that 37% of landfill cells contained MSW ash; of these cells, 90% of them are considered ETLFs. ETLF cells are on-average double the site area and approximately 6 m deeper than the average non-ETLF cell. Furthermore, results suggest that heat propagation in most landfills is limited; however, heat propagation is possible if gas wells are turned off for an extended time period.Co-processing of lignocellulosic wastes, e.g., garden and paper wastes, and the organic matters fraction of municipal solid waste (OMSW) in an integrated bioprocess is a possible approach to realize the potential of wastes for biobutanol production. Dilute acid pretreatment is a multi-functional stage for breaking the recalcitrant lignocellulose's structure, hydrolyzing hemicellulose, and hydrolyzing/solubilizing starch, leading to a pretreated solid and a rich hydrolysate. In this study, dilute-acid pretreatment of the combination of wastepaper and OMSW, composite I, as well as garden waste and OMSW, composite II, at severe conditions resulted in "pretreatment hydrolysates" containing 33.7 and 19.4 g/L sugar along with 18.9 and 33.2 g/L soluble starch, respectively. In addition, the hydrolysis of solid remained after the pretreatment of composite I and II resulted in "enzymatic hydrolysates" comprising 19.4 and 33 g/L sugar, respectively. The fermentation of the pretreatment hydrolysates and enzymatic hydrolysates resulted in 3.5 and 6.4 g/L ABE from composite I and 15 and 5.2 g/L ABE from composite II, respectively. In this process, 148 and 173 g ABE (60 and 100 g gasoline equivalent/kg) was obtained from each kg composite I and composite II, respectively, where co-processing of OMSW with lignocellulosic wastes resulted in 10 and 49% higher ABE than that produced from the individual substrates.This research proposed to investigate a possible destination for the cocoa waste as component in the core layer of Medium Density Particleboards (MDPs) and to evaluate the effect of the waste insertion on the physical-mechanical properties of the panel. The core layers of the MDPs were composed by different percentages of cocoa wastes (0, 25, 50, 75 and 100%) in combination with pine wood. The targeted density of the panels was pre-established in 0.7 g cm-3, bonded with urea-formaldehyde. The cocoa waste showed higher extractives content (34.8%) when compared with the pine wood (4.0%). The inclusion of the waste did not cause a significant difference in the moisture and bulk density of the panels; however, there was an increase in water absorption 24 h (71-105%) and thickness swelling 24 h (13-35%). Despite the values of the mechanical properties decreased in general, in low percentages, the cocoa waste does not prevent the use of the MDPs as furniture for internal environments. The results show that the cocoa waste has potential for being applied as raw material in the core layer of the MDP, in percentages up to 21%. The lignocellulosic wastes are promising alternatives for the achievement of the required current context of the sustainability and should be highlighted with research focused on their management for the development of added value materials.The recent developments of high-throughput bulk and single-cell sequencing technologies accelerated the understanding of the complexity of immune repertoire dynamics combined to transcriptomics. Also, profiling of cellular repertoires in health or disease requires statistical metrics to capture clonal diversity characterized by clones frequency, repertoire richness and convergence. Here we present the common technologies of bulk and single-cell sequencing of T-cell receptors (TCRs), discuss current knowledge regarding computational tools clustering and predicting specificity of TCR repertoires based on shared structural motifs and review main indices for repertoire diversity and convergence analyses. These tools represent potential biomarkers to decipher the fitness of immune repertoires in diseased or treated patients but also the presages and promises of computational approaches to revolutionize personalized immunotherapy.
The finalized 'Deeming Rule' extended the Food and Drug Administration (FDA) authority to regulate e-cigarettes, cigars, and other newly deemed tobacco products. We seek to assess the neighborhood characteristics associated with retail violations of sales to minors (RVSM) by tobacco product.
We collected national inspection data on tobacco retailers during August 8, 2016, and May 31, 2018, from the FDA compliance check database.
A web scraping tool was applied to text mine the FDA decision letters and extract information on the tobacco product involved in RVSM. Separate logistic regression models with random effects were performed to examine the association between zip code-level neighborhood characteristics and RVSM by tobacco product.
Of 268,317 minor-involved compliance inspections, 35,403 (13.2%) were identified as RVSM. Among 23,352 warning letters included in the final analysis, e-cigarettes, cigars, cigarettes, and smokeless tobacco accounted for 20.0% (n=4673), 40.4% (9439), 35.6% (8303), and 4.0% (937) of RVSM, respectively. Flavored tobacco products were abundant among underage sales. For e-cigarettes, RVSM were more likely to occur in zip codes with a larger proportion of youth population aged 10-17 years (adjusted odds ratio [AOR]=1.17 [1.02-1.34]). A larger proportion of African Americans was associated with a higher risk of RVSM for cigars (AOR=1.09 [1.07-1.11]) but a lower risk of RVSM for e-cigarettes (AOR=0.90 [0.87-0.93]).
Retail violations of underage sales for cigars and e-cigarettes are prevalent and neighborhood characteristics associated with violations differ by tobacco product. Continued inspections with tailored strategies to reduce RVSM of all tobacco products are needed.

This study aims to further quantify evidence of the association between exposure to indoor air pollution (IAP), tobacco smoke etc., on the one hand and the risk of contracting tuberculosis (TB) on the other.
This was a systematic review and meta-analysis of articles published between June 2014 and February 2020 in PubMed, Web of Science, among others.
We only included studies that controlled for confounders, screened both the exposed and unexposed study participants, and passive smoking studies that limited the study population to non-smokers. Quality of studies was assessed using the Newcastle-Ottawa scale. The analysis was conducted using STATA, and pooled effect sizes were calculated using the random-effects model, and heterogeneity was tested for using the Cochran Q test and I
statistic.
A total of 26 articles were included in the final analysis. There was an increased risk of contracting TB among people exposed to IAP (risk ratio [RR]=1.68, 95% confidence interval [CI] 1.108-2.542). We also observed a two-fold increase in the risk of contracting TB from exposure to secondhand tobacco smoke (RR=2.
