2024 White paper on recent issues in bioanalysis: Impact of LDT in US and IVDR in EU; AI/ML for High Parameter Flow Cytometry; The rise of Olink Technology; CDx for AAV Gene Therapies; Integrative Bioanalysis by Multiple Platforms; Super Sensitive ADA/NAb LBA ( - Recommendations on Advanced Strategies for Biomarkers, IVD/CDx Assays (BAV), Cell Based Assays (CBA), and Ligand-Binding Assays (LBA) - Regulatory Agencies' Input on Biomarkers, IVD/CDx, and Biomarker Assay Validation).

The 18th Workshop on Recent Issues in Bioanalysis (18th WRIB) took place in San Antonio, TX, USA on May 6-10, 2024. Over 1100 professionals representing pharma/biotech companies, CROs, and multiple regulatory agencies convened to actively discuss the most current topics of interest in bioanalysis. The 18th WRIB included 3 Main Workshops and 7 Specialized Workshops that together spanned 1 week to allow an exhaustive and thorough coverage of all major issues in bioanalysis of biomarkers, immunogenicity, gene therapy, cell therapy and vaccines.

Antinociceptive effect and mechanism of supercritical carbon dioxide extract of Aloysia gratissima leaves in mice.

Background: A. gratissima is a shrub used in folk medicine as analgesic and sedative. However, studies on its antinociceptive activity are scarce.

A fertility-oriented method for histological processing of testicular biopsies in men with azoospermia.

The present study was designed to evaluate whether tissue preparation by glutaraldehyde and glycol methacrylate (G/GMA) improves the diagnostic assessment of testicular biopsies from azoospermic men when compared to the standard tissue preparation using Bouin's solution and paraffin. We prospectively included a total of 21 testicular biopsies of sexually mature men aged 29-50 years with infertility and azoospermia. One testicular biopsy fragment from each patient was processed by the G/GMA method, whereas another tissue fragment was contemporarily processed by the conventional Bouin/paraffin (B/P) method.

[Urinary Retention Due to Hematocolpos].

Hematocolpos is an obstruction of the menstrual flow due to an anomaly of the genital tract, with imperforate hymen being the most common one. It is an uncommon condition, with a prevalence of 1:1000 - 1:16 000. It is usually an asymptomatic condition until the onset of menarche, when there is accumulation of blood in the vagina (hematocolpos) or in the uterus (hematometra).

[Impact assessment of the implementation of an integrated care model for thyroid disease at the University Hospital "Federico II" of Naples (Campania Region, Southern Italy): an interrupted time series analysis].

Objectives: to evaluate the implementation of an integrated care model for thyroid disease on thyroid surgery at the University Hospital "Federico II" of Naples (Campania Region, Southern Italy).

Design: quasi-experimental design employing an interrupted time series analysis.

Setting And Participants: all subjects who were admitted to the University Hospital "Federico II" for thyroid surgery between January 2008 and December 2018.
