The success of virus transmission by vectors relies on intricate trophic interactions between three partners, the host plant, the virus, and the vector. Despite numerous studies that showed the capacity of plant viruses to manipulate their host plant to their benefit, and potentially of their transmission, the molecular mechanisms sustaining this phenomenon has not yet been extensively analyzed at the molecular level. In this study, we focused on the deregulations induced in by an aphid vector that were alleviated when the plants were infected with turnip yellows virus (TuYV), a polerovirus strictly transmitted by aphids in a circulative and nonpropagative mode.

To avoid the activation of plant defenses and ensure sustained feeding, aphids are assumed to use their mouthparts to deliver effectors into plant cells. A recent study has shown that effectors detected near feeding sites are differentially distributed in plant tissues. However, the precise process of effector delivery into specific plant compartments is unknown.

The presence of SARS-CoV-2 RNA has been extensively reported at the influent of wastewater treatment plants (WWTPs) worldwide, and its monitoring has been proposed as a potential surveillance tool to early alert of epidemic outbreaks. However, the fate of the SARS-CoV-2 RNA in the treatment process of WWTP has not been widely studied yet; therefore, in this study, we aimed to evaluate the efficiency of treatment processes in reducing SARS-CoV-2 RNA levels in wastewater. The treatment process of three WWTPs of the Parisian area in France was monitored on six different weeks over a period of 2 months (from April 14 to June 9, 2021).

Background: Even after resection of early-stage non-small-cell lung cancer (NSCLC), patients have a high risk of developing recurrence and second primary lung cancer. We aimed to assess efficacy of a follow-up approach including clinic visits, chest x-rays, chest CT scans, and fibre-optic bronchoscopy versus clinical visits and chest x-rays after surgery for resectable NSCLC.

Methods: In this multicentre, open-label, randomised, phase 3 trial (IFCT-0302), patients aged 18 years or older and after complete resection of pathological stage I-IIIA NSCLC according to the sixth edition of the TNM classification were enrolled within 8 weeks of resection from 122 hospitals and tertiary centres in France.

Article Synopsis
  • Targeted therapies (TT) and immune checkpoint blockers (ICB) are changing the treatment landscape for non-small cell lung cancer (NSCLC), but their effectiveness as maintenance therapies after first-line chemotherapy is unclear.
  • The SAFIR02-Lung trial involved 175 patients receiving various TT and 59 receiving standard care, showing no significant difference in progression-free survival (PFS) between the two groups.
  • The study concluded that while molecular profiling for treatment decisions can be managed, it didn’t show significant advantages for most patients, except those with a specific PD-L1 tumor score who benefited more from durvalumab treatment.

Purpose: Roughly 20% of patients with non-small-cell lung cancer exhibit locally advanced, unresectable, stage III disease. Concurrent platinum-based chemoradiotherapy is the backbone treatment, which is followed by maintenance immunotherapy, yet with poor long-term prognosis. This phase II trial (IFCT-0803) sought to evaluate whether adding cetuximab to cisplatin and pemetrexed chemoradiotherapy would improve its efficacy in these patients.

Background: Benefit from maintenance in advanced non-squamous non-small cell lung cancer (NS-NSCLC) might favor switch maintenance after disease stabilization (SD) and continuation after objective response (OR). This trial assessed a maintenance strategy conditioned by response to cisplatin-gemcitabine (CG) with G continuation for patients with OR or switch to pemetrexed (P) for patients with SD as compared with a control arm based on the Paramount regimen.

Methods: Eligibility criteria: age 18-70 years, ECOG PS 0-1, untreated stage IV NS-NSCLC without EGFR or ALK alteration, ineligibility to bevacizumab.

Background: Thymic carcinomas are aggressive and difficult to treat a subset of thymic epithelial tumours that represent a heterogeneous group of rare intrathoracic malignancies. The treatment strategy of thymic carcinomas is based on whether surgical resection may be achieved, which represents the most significant favourable prognostic factor on survival. For this study, we took advantage of the unique prospective Réseau tumeurs THYMiques et Cancer (RYTHMIC) database to describe baseline characteristics, analyse treatment strategies in light of existing guidelines and provide landmark patient outcomes data with regards to response and survival of patients in a real-life clinical practice setting.

Neonicotinoids are widely used to protect fields against aphid-borne viral diseases. The recent ban of these chemical compounds in the European Union has strongly impacted rapeseed and sugar beet growing practices. The poor sustainability of other insecticide families and the low efficiency of prophylactic methods to control aphid populations and pathogen introduction strengthen the need to characterize the efficiency of new plant protection products targeting aphids.

Background: In patients with non-small-cell lung cancer (NSCLC), the use of postoperative radiotherapy (PORT) has been controversial since 1998, because of one meta-analysis showing a deleterious effect on survival in patients with pN0 and pN1, but with an unclear effect in patients with pN2 NSCLC. Because many changes have occurred in the management of patients with NSCLC, the role of three-dimensional (3D) conformal PORT warrants further investigation in patients with stage IIIAN2 NSCLC. The aim of this study was to establish whether PORT should be part of their standard treatment.

Introduction: Thymomas are rare intrathoracic malignancies that may be aggressive and difficult to treat. Knowledge and level of evidence for treatment strategies are mainly based on retrospective studies or expert opinion. Currently there is no strong evidence that postoperative radiotherapy after complete resection of localized thymoma is associated with survival benefit in patients.

Turnip yellows virus (TuYV), transmitted by , can be controlled in rapeseed fields by insecticide treatments. However, the recent ban of the neonicotinoids together with the description of pyrethrinoid-resistant aphids has weakened insecticide-based control methods available to farmers. Since the deployment of insecticides in the 1980s, few research efforts were made to breed for rapeseed cultivars resistant to aphid-borne viral diseases.

Purpose: Second-line chemotherapy regimens have demonstrated poor benefit after failure of platinum-based chemotherapy in advanced non-squamous non-small-cell lung cancer (nsNSCLC).

Methods: In this multicentre, open-label phase III trial, patients with advanced nsNSCLC treated with one or two prior lines, including one platinum-based doublet, were centrally randomised to receive 90 mg/m of paclitaxel (D1, D8, D15) plus 10 mg/kg of bevacizumab (D1, D15) every 28 days or docetaxel (75 mg/m) every 21 days; crossover was allowed after disease progression. Primary end-point was progression-free survival (PFS).
