Plant interactions are as important belowground as aboveground. Belowground plant interactions are however inherently difficult to quantify, as roots of different species are difficult to disentangle. Although for a couple of decades molecular techniques have been successfully applied to quantify root abundance, root identification and quantification in multispecies plant communities remains particularly challenging. Here we present a novel methodology, multispecies genotyping by sequencing (msGBS), as a next step to tackle this challenge. First, a multispecies meta-reference database containing thousands of gDNA clusters per species is created from GBS derived High Throughput Sequencing (HTS) reads. Second, GBS derived HTS reads from multispecies root samples are mapped to this meta-reference which, after a filter procedure to increase the taxonomic resolution, allows the parallel quantification of multiple species. The msGBS signal of 111 mock-mixture root samples, with up to 8 plant species per sample, was used to calculate the within-species abundance. Optional subsequent calibration yielded the across-species abundance. The within- and across-species abundances highly correlated (R2 range 0.72-0.94 and 0.85-0.98, respectively) to the biomass-based species abundance. Compared to a qPCR based method which was previously used to analyse the same set of samples, msGBS provided similar results. Additional data on 11 congener species groups within 105 natural field root samples showed high taxonomic resolution of the method. msGBS is highly scalable in terms of sensitivity and species numbers within samples, which is a major advantage compared to the qPCR method and advances our tools to reveal hidden belowground interactions.
In this study, we investigated the prognostic significance of a micropapillary (MP) component in patients with subcentimeter lung adenocarcinoma.

A total of 311 patients with subcentimeter lung adenocarcinoma who underwent surgical resection between January 2009 to December 2012 from seven medical centers were included. Recurrence-free survival (RFS) and overall survival (OS) were analyzed.

The five-year RFS was 79.8% in 97 (97/311, 31%) cases of adenocarcinoma with a MP component and 93.5% in the 214 (214/311, 69%) cases without. In multivariate analysis, MP was an independent risk factor for worse RFS (hazard ratio [HR], 3.73; 95% confidence interval [CI] 1.87-7.42; P < 0.001) and OS (HR, 5.84; 95% CI 2.20-15.49; P < 0.001). There was no significant difference among wedge resection, segmentectomy and lobectomy on RFS (P = 0.256) and OS (P = 0.103) in patients without MP. Regarding patients with a MP component, lobectomy achieved equivalent prognosis than segmentectomy, and both were better than wedge resection (P = 0.001).

A MP component still suggest a poor prognosis in subcentimeter lung adenocarcinoma. selleck compound Patients with subcentimeter lung adenocarcinoma with a MP component of 5% or greater treated with wedge resection were at higher risk of recurrence than patients treated with anatomical resection.

Immunotherapy has afforded new treatment options for extensive small cell lung cancer (ES-SCLC). However, reports on the effectiveness of immune checkpoint inhibitors (ICIs) combined with chemotherapy on survival in ES-SCLC patients are inconsistent. Therefore, we conducted a meta-analysis on the efficacy and safety of ICI combined with chemotherapy for ES-SCLC.

We searched for randomized controlled clinical trials related to first-line treatment of ES-SCLC with ICI combined with chemotherapy in PUBMED, ESMO, ASCO, and WCLC since 2018. The primary outcome was overall survival (OS).

Four studies were included. Compared to chemotherapy alone, ICI in combination with chemotherapy as first-line treatment reduced the risk of death (hazard ratio [HR] 0.76; 95% CI 0.68-0.86; P < 0.00001) and disease progression (HR 0.76; 95% CI 0.68-0.84; P < 0.00001). The objective response rate (ORR) with ICI plus chemotherapy was significantly higher than that with chemotherapy alone (HR 1.10; 95% CI 1.02-1.19, P = 0. ES-SCLC.
This study fills gaps regarding the efficacy of immunotherapy combined with chemotherapy as first-line treatment for ES-SCLC, and provides better evidence for the use of PD-L1/PD-1 immunotherapy plus chemotherapy for patients with ES-SCLC.With great interests, I carefully read the article by Valli De Re et al. in a recent issue of Liver International.1 The authors conducted a cohort study assessing the associations of polymorphisms of IFNL4 and PDCD1 genes on 734 hepatitis C virus (HCV)-positive patients, including 461 cases with liver disease of varying severity and 273 patients with lymphoproliferative disorders. The author indicated that IFNλ4 expression might contribute to the development of HCV-related hepatocellular carcinoma (HCC), and an epistatic contribution of IFNL4 and PDCD1 in mixed cryoglobulinemia (MC). However, some concerns should be interpreted cautiously in light of the following issues.
Patient advocacy is a core value in medical education. Although students learn about social determinants of health (SDH) in the pre-clinical years, applying this knowledge to patients during clerkship rotations is not prioritized. Physicians must be equipped to address social factors that affect health and recognize their roles as patient advocates to improve care and promote health equity. We created an experience-based learning curriculum called Advocacy in Action (AiA) to promote the development and application of health advocacy knowledge and skills during an Internal Medicine (IM) clerkship rotation.

Sixty-six students completed a mandatory curriculum, including an introductory workshop on SDH and patient advocacy using tools for communication, counselling and collaboration skills. They then actively participated in patient advocacy activities, wrote about their experience and joined a small group debriefing about it. Forty-nine written reflections were reviewed for analysis of the impact of this curriculum on student perspectives.
