Lung cancer is the most common cancer diagnosis (about 1.8 million new cases per year), and the leading cause of cancer death (1.59 million deaths per year) in the world [1]. Currently, small-cell lung cancer (SCLC) accounts for 13% of all lung cancers, and more than 2/3 of the patients present with metastatic disease. As opposed to NSCLC, patients often have a bulky mediastinal disease at presentation, frequently with involvement of bilateral mediastinal lymph nodes. After staging procedures, SCLC...
We appreciate the opportunity to review the response of Dr. Cellini and colleagues to our manuscript “Recommendations on the use of radiation therapy in managing patients with gastrointestinal malignancies in the era of COVID-19.”1 We agree with Dr. Cellini that preoperative chemoradiation, and not preoperative chemotherapy, is and should remain the standard of care in the management of esophageal cancer, of either histology. As Dr. Cellini and colleagues point out, while there are no randomized...
Dear Editor, we read with interest the paper of Tchelebi et al. addressing the choices for optimizing clinical indication and resources along the current pandemic scenario [1]. In regard of locally advanced esophageal cancer they suggest to apply preoperative concurrent radiochemotherapy (pRTCT), being the standard option; it should be given using the shortest fractionation scheme possible. Finally, induction chemotherapy is mentioned as alternative to delay the initiation of daily radiotherapy,...
The COVID-19 pandemic has dramatically impacted surgical capacity, radiotherapy and chemotherapy delivery worldwide. Contributing factors include the importance of social distancing to reduce viral transmission, the recognition that cancer patients have a higher risk of severe events compared to non-cancer patients [1], and resource limitations of the cancer centre with limited personal protective equipment (PPE), staffing shortages due to illness and redeployment. Recommendations have been made...

Nature Communications, Published online: 13 July 2020; doi:10.1038/s41467-020-17209-1Reliable, multiplexed gene editing to uncover synergies between targets remains challenging. Here, the authors engineer AsCas12a and the crRNA to improve double knockout for synthetic sick/lethal interaction genetic screening.
Nature Communications, Published online: 13 July 2020; doi:10.1038/s41467-020-17270-wThe vCA1-BA projection is enriched in shock responsive neurons, which are necessary for fear memory encoding and become correlated with a network of neurons during retrieval. Here the authors show that the magnitude of vCA1 correlated activity is proportional to memory strength and requires the shock response during encoding.
Nature Communications, Published online: 13 July 2020; doi:10.1038/s41467-020-17300-7It is unclear whether 2D metal dichalcogenides (TMD) alone can cause ferroptotic cell death. Here, the authors show TMD nanosheets induced ferroptosis in mammalian cell lines and in a mouse model after aspiration of TMD materials into lungs, causing ferroptotic cell death.
Nature Communications, Published online: 13 July 2020; doi:10.1038/s41467-020-17113-8Mice are able to discriminate colors, at least in the upper visual field. Here, the authors provide a comprehensive characterization of retinal circuits underlying this behavior.
Nature Communications, Published online: 13 July 2020; doi:10.1038/s41467-020-17212-6Melanosomes traffic along F-actin in melanocytes. Here, the authors show that Rab27a coordinates SPIRE/FMN actin assembly and MyoVa motor proteins to generate a cell-wide actin/myosin network that links melanosomes and allows the collective activity of these force generators to drive their traffic.
Nature Communications, Published online: 13 July 2020; doi:10.1038/s41467-020-17255-9Explicit self-reflection is unreliable for measuring thoughts. Here, the authors use brain data to implicitly pinpoint transitions between thoughts and find thought turnover to be reliably predicted by narrative events during movie-viewing, as well as by greater trait neuroticism at rest.

Abstract If a patient’s cancer progresses while undergoing targeted therapy, a re-biopsy is not mandatory. But when evaluating the benefits and risks on a case-by-case basis (transformation to small cell, assessing for a clinical trial), physicians should inform patients about the possible need for a re-biopsy (5). This was a retrospective and multicentre study. A total of 644 patients with lung adenocarcinoma were reviewed, 625 of whom were ruled eligible. From them, 399 were...
Abstract We tested the prognostic relevance of metabolic parameters and their relative changes in patients with metastatic colorectal cancer (mCRC) treated with monoclonal antibody and chemotherapy. SUVmax (standardized uptake volume), SAM (standardized added metabolic activity) and TLG (total lesion glycolysis) are assessed with 18F-fluorodeoxyglucosepositron emission tomography and computed tomography (FDG-PET/CT) to evaluate total metabolic activity of malignant processes....
Abstract There is no evidence that prolonged pre diagnostic symptomatic intervals (PSI) increases the risk of death in pediatric brain tumors. When investigating the role of time previous research had not controlled for confounding variables or measured the pretreatment interval (PTI). We use the term global delay interval (GDI) to describe the sum of PSI and PTI. The aim of this research was to evaluate whether there was a decrease in the probability of survival in children with...

Natural products are used as alternative drugs in traditional medicine to treat infection and inflammation and relieve pain. Heartwood of Cassia garettiana Craib has been investigated as an ingredient in Thai traditional medicine for anti-HIV protease, but there is no report on its antibacterial and anti-inflammatory activities. The objectives of this study were to investigate the anti-inflammatory and antibacterial activities, time-kill profile, and main active constituents of an ethanolic extract...
Deep borehole heat exchanger (DBHE) technology does not depend on the existence of hot water reservoir and can be used in various regions. However, the heat extraction from DBHE can hardly be improved due to poor thermal conductivity of rocks. Here, a single-well enhanced geothermal system (SWEGS) is proposed, which has a larger heat-exchange area of artificial reservoir created by fracturing hydrothermal technology. We find that, due to heat convection between rocks and fluid, the extracted thermal...

Summary Fusions involving neurotrophic tyrosine receptor kinase (NTRK) are known drivers of oncogenesis and also occur in melanoma, although very rarely. A particularly high incidence of NTRK gene fusions is reported in infantile fibrosarcoma (> 90 %) or the secretory type of breast cancer (> 90 %). Recently, larotrectinib (a tropomyosin receptor kinase [TRK] inhibitor) was approved, and we wondered whether TRK inhibitors might also be helpful for melanoma patients. We therefore screened...
