A scoping review on tools and methods for trait prioritization in crop breeding programmes.

Trait prioritization studies have guided research, development and investment decisions for public-sector crop breeding programmes since the 1970s, but the research design, methods and tools underpinning these studies are not well understood. We used PRISMA-ScR (Preferred Reporting Items for Systematic review and Meta-Analysis Protocols) to evaluate research on trait ranking for major crops over the past 40 years (1980-2023). Data extraction and descriptive analysis on 657 papers show uneven attention to crops, lack of systematic sex disaggregation and regional bias. The lack of standardized trait data taxonomy across studies, and inconsistent research design and data collection practices make cross-comparison of findings impossible. In addition, network mapping of authors and donors shows patterns of concentration and the presence of silos within research areas. This study contributes to the next generation of innovation in trait preference studies to produce more inclusive, demand-driven varietal design that moves beyond trait prioritization focused on productivity and yield.

Evaluation of the intraocular pressure changes during micturition in patients with benign prostatic hyperplasia.

OBJECTIVE: To evaluate the effect of the Valsalva maneuver (VM) during micturition on intraocular pressure (IOP) in patients with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: IOP were measured before and during micturition in uroflowmetry testing by Tonopen-Avia (Reichert Inc., NY, USA) in 35 eyes of 35 patients with BPH. International Prostate Symptoms Score (IPSS) questionnaire was used for quantification of BPH symptoms. The subjects were divided into two groups according to IPSS questionnaire: patients with low IPSS scores and patients with high IPSS scores. RESULTS: The mean IOP before and during micturition in patients with BPH were 15.26 ± 4.39 mmHg and 16.23 ± 4.43 mmHg, respectively (p = 0.047). When patients with BPH were assigned to two distinct groups according to the IPSS scores, IOP did not differ in patients with low IPSS scores (p = 0.590), whereas mean IOP was significantly higher in patients with high IPSS scores (p = 0.007). CONCLUSIONS: The Valsalva maneuver, performed during micturition, can lead to significant IOP increase in patients with BPH, particularly in advanced disease.
