Nivolumab, an anti-programmed cell death-1 (PD-1) monoclonal antibody with immune checkpoint inhibitory activity, represents a novel treatment for several cancers. Immune checkpoint inhibitors cause side effects, known as immune-related adverse events (irAEs) or delayed immune-related events (DIRE), after immunotherapy discontinuation. Type 1 diabetes mellitus (T1DM) and diabetic ketoacidosis have been reported to develop as an irAE during the treatment with nivolumab. Here, we report on a patient who developed T1DM and diabetic ketoacidosis after discontinuation of treatment with nivolumab as a DIRE.

A 59-year-old man, who received nivolumab for an alpha fetoprotein-producing gastric cancer, presented with acute fatigue 4months after discontinuation of nivolumab. Throughout therapy with nivolumab, the patient's hemoglobin A1c (HbA1c) level was ≤ 6%. However, 1month prior to the patient's emergency department visit, he noticed weight loss, and 3weeks prior to that, his HbA1c was 7.1%. Urinalysis showed keent visit, he noticed weight loss, and 3 weeks prior to that, his HbA1c was 7.1%. Urinalysis showed ketone bodies, and arterial blood gas analysis suggested metabolic acidosis with hyperglycemia (690 mg/dL), which established the diagnosis of diabetic ketoacidosis. An endogenous insulin deficiency without verifiable anti-islet autoantibodies was confirmed; the patient had a human leukocyte antigen haplotype that does not increase the risk of acute-onset T1DM. We considered that T1DM in this patient developed possibly due to nivolumab. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? This case highlights the need for clinicians to be vigilant of the fact that a history of anti-PD-1 monoclonal antibody therapy may increase the risk of diabetic ketoacidosis, whether treatment is ongoing or discontinued.Developing high-efficient hybrids carbon catalysts for PMS-based advanced oxidation process (AOPs) are crucial in the field of environmental remediation. In this work, novel carbon nanocubes (xFe‒N‒C) with three-dimensional porous structure and abundant well-dispersed FeNx sites were obtained via a skillful cage-encapsulated-precursor pyrolysis strategy. The as-synthesized xFe‒N‒C exhibited superb activity for phenol degradation by activating peroxymonosulfate (PMS). Besides, the catalytic system not only possessed good recycling performance, wide pH adaptation and relatively low activation energy, but also had high resistance to environmental interference. Singlet oxygen (1O2) dominated non-radical process was responsible for phenol degradation rather than traditional radical pathways. Impressively, the doping level of Fe could regulate FeNx contents in catalysts, and the catalytic activity of xFe‒N‒C was greatly enhanced with increasing FeNx contents. Based on density functional theory calculations (DFT), the introduction of FeNx sites regulated the electronic structure of catalysts. Such electron-deficient Fe center acted as electron acceptor to receive electrons transmitted by the adsorbed PMS, thus generating highly reactive 1O2 for rapid phenol oxidation. This work provides a new insight into the innovation in transition metal-nitrogen hybrid carbon catalysts and highlights the pivotal roles of FeNx sites in 1O2 generation during PMS activation process.Soil copper (Cu) pollution severely stunts crops growth and limits sustainable agri-food production. read more Many microbes are widely used for remediation of polluted soil, including Cu pollution. In this study, the potential of an endophytic Bacillus altitudinis WR10 to protect wheat from Cu stress and the molecular mechanisms were investigated using hydroponic model. The Cu resistance assay showed B. altitudinis WR10 can resist up to 2 mM Cu and remove about 74% Cu in medium after 24 h of fermentation. Co-culture study demonstrated WR10 increased roots length and dry weight in wheat seedlings under 50 μM Cu. These results indicated that WR10 was a Cu-resistant strain and reduced Cu toxicity in wheat. Transcriptome data and biochemical tests of wheat roots indicated that WR10 alleviated Cu toxicity through enhancing peroxidases (PODs) gene expression and activity to remove excess hydrogen peroxide (H2O2) and down-regulating glutathione S-transferases (GSTs) to increase glutathione (GSH) level. Moreover, enrichment and pathway analysis indicated WR10 regulated the expression of genes involved in phenylpropanoid biosynthesis, which may improve phenolic acids accumulation for protecting plant cells from Cu toxicity. Overall, this study revealed that B. altitudinis WR10 alleviated Cu toxicity in wheat via augmenting reactive oxygen species scavenging and phenylpropanoid biosynthesis.A novel CO2-responsive cellulose nanofibril aerogel as a "green" adsorbent derived from poly(methacrylic acid-co-2-(dimethylamino) ethyl methacrylate) and carboxylated cellulose nanofibrils was successfully prepared via stepwise cation-induced gelation and freeze drying method. This aerogel exhibited CO2-triggered adsorption behavior towards anionic dyes with a rapid adsorption rate and a high adsorption capacity, as well as satisfactory mechanical properties. Upon CO2 stimulation, the charged aerogel can selectively adsorb anionic dyes from aqueous solutions based on an electrostatic interaction. The maximum adsorption capacities of this aerogel towards methyl blue (MB), naphthol green B (NGB), and methyl orange (MO) were 598.8, 621.1 and 892.9 mg g-1, respectively, accompanied by fast adsorption equilibriums towards MB and NGB within 7 min, and MO within 12 min. Meanwhile, the adsorption isotherms and the kinetics of the CO2-responsive adsorbents followed the Freundlich isotherm and the pseudo-second-order model, respectively. Furthermore, the resulting CO2-responsive adsorbent exhibited outstanding recyclability, as its adsorption performance can still be maintained even after twenty cycles. Accordingly, the resultant CO2-responsive cellulose nanofibril aerogel could be a promising adsorbent material for the removal of anionic dyes in wastewater remediation.Biogenic Fe(II) is a dominant natural reductant to convert carcinogenic Cr(VI) to less toxic Cr(III). Field-applied biochar could promote microbial production of Fe(II) and form iron-biochar composites. Although there have been mounting research on the interactions of biochar or Fe(II) with Cr(VI), their coupling effects on Cr(VI) immobilization have been largely neglected. Here, iron mineral-biochar composite (IMBC) was prepared via biochar-mediated dissimilatory reduction of ferrihydrite or goethite by Shewanella oneidensis MR-1, and its reaction with Cr(VI) was investigated. IMBC was able to effectively remove aqueous Cr(VI) via reductive transformation by adsorbed Fe(II). The removal process nicely followed pseudo-second-order kinetics and Langmuir isotherm model. The removal ability of IMBC decreased with increasing pH (5.5-8.0) but was independent of ionic strength changes (0-100 mM). After reaction, the Fe-Cr coprecipitates formed on IMBC exhibited slightly higher Fe/Cr ratios (0.93-0.96) than those on corresponding iron mineral controls (0.
