Outcomes from studies assessing exposure often use multiple measurements. In previous work, using a model first proposed by Buonoccorsi (1991), we showed that combining direct (eg, biomarkers) and indirect (eg, self-report) measurements provides a more accurate picture of true exposure than estimates obtained when using a single type of measurement. In this article, we propose a tool for efficient design of studies that include both direct and indirect measurements of a relevant outcome. Based on data from a pilot or preliminary study, the tool, which is available online as a shiny app at https//michalbitan.shinyapps.io/shinyApp/, can be used to compute (1) the sample size required for a statistical power analysis, while optimizing the percent of participants who should provide direct measures of exposure (biomarkers) in addition to the indirect (self-report) measures provided by all participants; (2) the ideal number of replicates; and (3) the allocation of resources to intervention and control arms.

In these examples, a near-optimal allocation of the resources can be found even if the assumptions are not precise.Compared with HLA-A*24020101, the alleles HLA-A*2402129 and HLA-A*2402135 each show one nucleotide substitution, respectively.This study aimed to study the characteristics and subpopulations of spermatozoa from bulls with low and high reproductive performance based on pregnancy rates. Based on historical records of pregnancy rate from four farms, 24 bulls were selected. Two groups were established, with low pregnancy rates (n = 12; LOW), including bulls that presented pregnancy rates 52.27% (52.27% to 69.64%), after fixed-time artificial insemination (FTAI). The thawed sperm straws were analysed to sperm kinetics, morphology, plasma membrane integrity and sperm subpopulations. The LOW group exhibited a higher proportion of static cells (p less then .05). In contrast, the HIGH group showed greater percentages for membrane integrity and total and progressive motility, and cells with fast and medium velocity (p less then .05). In the cluster procedures, four sperm subpopulations were established. The low-fertility bulls presented the highest percentage of subpopulation 2 (41.46%), characterized by slow and progressive spermatozoa. The high-fertility bulls exhibited the highest percentage of subpopulation 3 (37.17%), characterized by fast and nonlinear spermatozoa. Results from this study indicated that bulls with greater percentages of fast and nonlinear spermatozoa seem to have greater fertilization capacity and the subpopulations analysis can be considered a tool to identify ejaculates with high fertility. Invasive fusariosis is a serious infection affecting mostly patients with haematologic malignancies and hematopoietic cell transplant recipients. To develop a scoring tool that evaluates guideline adherence in the management of invasive fusariosis. We reviewed two guidelines, provided by the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) and the European Confederation of Medical Mycology (ECMM), and selected the strongest recommendations for management quality as the bases for the scoring tool. We reviewed the recommendations regarding primary and secondary prophylaxis, diagnostics procedures (images, blood cultures, biopsy of skin lesions with direct examination, culture and histopathology, species identification, antifungal susceptibility tests and antigen detection), treatment choices and follow-up procedures. The tool comprises 18 items, with a maximum of 24 points. The EQUAL score Fusariosis is a tool that may help clinicians to measure guidelines adherence.
