SRTR uses data collected by OPTN to calculate metrics such as donation rate, organ yield, and rate of organs recovered for transplant but not transplanted. In 2019, there were 11,870 deceased donors, an increase from 10,721 in 2018; this number has been increasing since 2010. The number of deceased donor transplants increased to 32,313 in 2019, from 29,675 in 2018; this number has been increasing since 2012. The increase may be due in part to the rising number of deaths of young people due to the ongoing opioid epidemic. The number of organs transplanted included 17,425 kidneys, 1,018 pancreata, 8,275 livers, 81 intestines, 3,604 hearts, and 2,607 lungs. In 2019, 4,324 kidneys, 346 pancreata, 867 livers, 5 intestines, 31 hearts, and 148 lungs were discarded. These numbers suggest an opportunity to increase numbers of transplants by reducing discards.
Methylorubrum extorquens AM1 can be engineered to convert methanol to value-added chemicals. Most of these chemicals derive from acetyl-CoA involved in the serine cycle. However, recent studies on methylotrophic metabolism have suggested that C3 pyruvate is a good potential precursor for broadening the types of synthesized products.

In the present study, we found that isobutanol was a model chemical that could be generated from pyruvate through a 2-keto acid pathway. Initially, the engineered M. extorquens AM1 could only produce a trace amount of isobutanol at 0.62mgL
after introducing the heterologous 2-ketoisovalerate decarboxylase and alcohol dehydrogenase. Furthermore, the metabolomic analysis revealed that insufficient carbon fluxes through 2-ketoisovalerate and pyruvate were the key limitation steps for efficient biosynthesis of isobutanol. Based on this analysis, the titer of isobutanol was improved by over 20-fold after overexpressing alsS gene encoding acetolactate synthase and deleting ldhA gene for lactate dehydrogenase. Moreover, substituting the cell chassis with the isobutanol-tolerant strain isolated from adaptive evolution of M. extorquens AM1 further increased the production of isobutanol by 1.7-fold, resulting in the final titer of 19mgL
in flask cultivation.

Our current findings provided promising insights into engineering methylotrophic cell factories capable of converting methanol to isobutanol or value-added chemicals using pyruvate as the precursor.

Following completion of six cycles of neoadjuvant chemotherapy over a three-month period, the patient returned for restaging. The adrenal nodule had increased in size and had undergone necrosis with just a fine cuff of residual viable lesion at the margins. It is thought that chemotherapeutic agents should not lead to significant cell death of an adrenal adenoma, and this produced diagnostic uncertainty. Interestingly, the lesion was subsequently biopsied under CT with histology confirming a classic adrenal adenoma. This rare case challenges our understanding of chemotherapeutic effects on adrenal adenomas, and offers another differential when assessing necrotic adrenal lesions.Biomass electro-oxidation is a promising approach for the sustainable generation of H2 by electrolysis with simultaneous synthesis of value-added chemicals. In this work, the electro-oxidation of two structurally different organic hydroxyacids, lactic acid and gluconic acid, was studied comparatively to understand how the chemical structure of the hydroxyacid affects the electrochemical reactivity under various conditions. It was concluded that hydroxyacids such as gluconic acid, with a considerable density of C-OH groups, are highly reactive and promising for the sustainable generation of H2 by electrolysis at low potentials and high conversion rates (less than -0.15 V vs. Hg/HgO at 400 mA cm-2 ) but with low selectivity to specific final products. In contrast, the lower reactivity of lactic acid did not enable H2 generation at very high conversion rates ( less then 100 mA cm-2 ), but the reaction was significantly more selective (64 % to pyruvic acid). This work shows the potential of biomass-based organic hydroxyacids for sustainable generation of H2 and highlights the importance of the chemical structure on the reactivity and selectivity of the electro-oxidation reactions.
Although tissue protrusion (TP) between the stent struts after stent implantation has been implicate as a potential factor of stent failure, the incidence, natural history, and predictive factor of TP after stent implantation remains unclear. This prospective study evaluated the fate of TP after drug-eluting stent (DES) deployment using optical coherence tomography (OCT).

This study analyzed TP for 42 lesions after DES in which three serial OCTs, including preprocedure, postprocedure, and 1-month after the procedure were performed. check details TP was classified into the five groups (a) persistent, (b) progressive, (c) healed, (d) regressive, and (e) late-acquired. Immediately after the procedure, 100 TPs in 37 lesions (88%) were identified. Of those, 53 (53%) were persistent, 3 (3%) were progressive, 20 (20%) were healed, and 24 (24%) were regressed at 1-month follow-up. Seven TPs in five patients (13%) were observed only at 1-month follow-up (late-acquired).

In lesions with late-acquired TP, calcified nodule was identified as an underlying plaque morphology on preprocedural OCT. A serial OCT analysis found TP occurred not only immediately after DES implantation, but also 1-month after DES implantation.

Hemophagocytic lymphohistiocytosis (HLH) is a rare syndrome of pathologic immune activation. Most studies on adult HLH have evaluated prognostic factors for overall survival; factors predicting early mortality have not been sufficiently investigated.

This was a collaborative study between Henry Ford Hospital and Barnes-Jewish Hospital. We identified all adult HLH patients with at least 2 ferritin levels within 30days from admission.

One-hundred twenty-four patients were identified. There were 77 males and 47 females; the median age at diagnosis was 48years. Multivariate analysis showed that age (OR=11.41; 95% CI2.71-48.04; P=.001), hepatomegaly (OR=15.68; 95% CI3.24-75.96; P=.001), hyponatremia (OR=5.94; 95% CI1.76-20.1; P=.004), hypoalbuminemia (OR=7.47; 95% CI2.08-26.85; P=.002), and increasing ferritin levels (OR=19.46; 95% CI4.69-80.71; P<.001) were significant predictors of 30-day mortality. Patients with declining ferritin by more than 35% from the ferritin peak were more likely to survive the first 30days of admission (OR=4.
