Asymmetry of investment in crop research leads to knowledge gaps and lost opportunities to accelerate genetic gain through identifying new sources and combinations of traits and alleles. On the basis of consultation with scientists from most major seed companies, we identified several research areas with three common features (i) relatively underrepresented in the literature; (ii) high probability of boosting productivity in a wide range of crops and environments; and (iii) could be researched in 'precompetitive' space, leveraging previous knowledge, and thereby improving models that guide crop breeding and management decisions. click here Areas identified included research into hormones, recombination, respiration, roots, and source-sink, which, along with new opportunities in phenomics, genomics, and bioinformatics, make it more feasible to explore crop genetic resources and improve breeding strategies.Over the past decade, genomics-assisted breeding (GAB) has been instrumental in harnessing the potential of modern genome resources and characterizing and exploiting allelic variation for germplasm enhancement and cultivar development. Sustaining GAB in the future (GAB 2.0) will rely upon a suite of new approaches that fast-track targeted manipulation of allelic variation for creating novel diversity and facilitate their rapid and efficient incorporation in crop improvement programs. Genomic breeding strategies that optimize crop genomes with accumulation of beneficial alleles and purging of deleterious alleles will be indispensable for designing future crops. In coming decades, GAB 2.0 is expected to play a crucial role in breeding more climate-smart crop cultivars with higher nutritional value in a cost-effective and timely manner.

Malignant pleural mesothelioma (MPM) remains a challenging disease to manage. In the past few decades, extrapleural pneumonectomy (EPP), pemetrexed-based chemotherapy, and indwelling pleural catheters were introduced to MPM care with variable levels of efficacy and evidence.

This was a retrospective review of patients diagnosed with MPM between January 1991 and March 2019. The primary outcome was overall survival (OS). Data were examined by decade to assess trends in MPM demographics, management, and OS. A subgroup analysis was then conducted to examine the impact of EPP, pemetrexed, and indwelling pleural catheters on OS.

The study included 337 patients; 309 patients had died at last follow-up (91.7%). Median age at diagnosis and the proportion of female patients increased from 65.8 years (interquartile range [IQR], 57.1-73.7) and 11.6% female from 1991 to 1999 to 75 years (IQR, 68.1-80.6) and 20.5% female from 2010 to 2019. Median OS was largely unchanged in the three study periods 9.0 months (95% confidence interval [CI], 6.9-12.7) in the 1991-1999 cohort, 9.3 months (95% CI, 7.6-13.2) in the 2000-2009 cohort, and 10.1 months (95% CI, 7.9-13.6) in the 2010-2019 cohort. Controlling for a number of demographic and prognostic factors, EPP (hazard ratio [HR]=0.50; 95% CI, 0.3-0.9; P=.02), pemetrexed-based chemotherapy (HR=0.59; 95% CI, 0.40-0.87; P=.007), and indwelling pleural catheters (HR=0.3; 95% CI, 0.13-0.71; P=.006) were each associated with improvements in OS.

Despite the small incremental improvements in survival shown by the three interventions we examined, prognosis remains guarded for MPM patients. Better modalities of management are needed.

As the risk of neurocognitive decline increases as people age, cognitive dysfunction is a potential complication in men with PC, imposing detrimental effects on functional independence and quality of life. Importantly, risk of cognitive decline may increase with exposure to androgen deprivation therapy and other hormonal therapies. Particular consideration should be given to patients with castration-resistant PC (CRPC), many of whom require continuous, long-term androgen deprivation therapy combined with a second-generation androgen receptor inhibitor. Non-comparative evidence from interventional trials of androgen receptor inhibitors in men with non-metastatic CRPC suggests differential effects on cognitive function and central nervous system-related adverse events within this drug class. Drug-drug interactions with concomitant medications for chronic, non-malignant comorbidities differ among ARIs and thus may contribute further to cognitive impairment. Hence, establishing baseline cognitive function is a prerequisite to identifying subsequent clinical decline associated with androgen receptor-targeted therapies. Although brief, sensitive screening tools for cancer-related cognitive dysfunction are lacking, mental status can be ascertained from the initial medical history and neurocognitive examination, progressing to more in-depth evaluation when impairment is suspected. On-treatment neurocognitive monitoring should be integrated into regular clinical follow-up to preserve cognitive function and quality of life throughout disease management. This review summarizes the multiple factors that may contribute to cognitive decline in men with CRPC, awareness of which will assist clinicians to optimize individual treatment. Practical, clinic-based strategies for managing the risks for and symptoms of cognitive dysfunction are also discussed.

Direct-acting antivirals are highly effective for the treatment of hepatitis C virus (HCV) infection, regardless race/ethnicity. We aimed to evaluate demographic, virological and clinical data of HCV-infected migrants vs. natives consecutively enrolled in the PITER cohort.

Migrants were defined by country of birth and nationality that was different from Italy. Mann-Whitney U test, Chi-squared test and multiple logistic regression were used.

Of 10,669 enrolled patients, 301 (2.8%) were migrants median age 47 vs. 62 years, (p<0.001), females 56.5% vs. 45.3%, (p<0.001), HBsAg positivity 3.8% vs. 1.4%, (p<0.05). Genotype 1b was prevalent in both groups, whereas genotype 4 was more prevalent in migrants (p<0.05). Liver disease severity and sustained virologic response (SVR) were similar. A higher prevalence of comorbidities was reported for natives compared to migrants (p<0.05). Liver disease progression cofactors (HBsAg, HIV coinfection, alcohol abuse, potential metabolic syndrome) were present in 39.
