Hair and/or nail analyses are sometimes used in biomonitoring studies due to the convenience of sample collection, storage, and transport, as well as the potential to assess past exposures to toxic metals, such as lead (Pb). However, the validity of Pb measurements in these keratinized matrices as biomarkers of absorbed dose remains unclear. The aim of this study was to examine the uptake of Pb into horns harvested postmortem from 11 goats that received a cumulative oral dose of up to 151 g Pb acetate over a period of 1-11 years as part of a long-term blood Pb proficiency testing program. Uptake of Pb into keratinized horn was compared to the corresponding underlying bony horn core, which, as part of the bone compartment, provided a measure of absorbed Pb dose. Two complementary analytical techniques were used to assess Pb X-Ray Fluorescence (XRF) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Detectable amounts of Pb were found in all keratinized horn samples (0.45-6.6 µg/g) and in all but one bony core sample (1.4-68 µg/g). In both bony core and keratinized horn samples, Pb accumulation increased with dose over a low-to-moderate cumulative-dose interval, consistent with previous observations, but plateaued at higher doses. Significant associations were observed between Pb in keratinized horn and bony core samples particularly with XRF measurements, which represent the surface bone compartment. These findings provide evidence that Pb is excreted in keratinized tissues but reflects only a small fraction of the absorbed Pb dose, likely transferred from underlying bone tissue.Introduction While sorafenib monotherapy represented the mainstay of medical treatment for advanced hepatocellular carcinoma (HCC) patients for more than a decade, novel agents and combination therapies have recently produced unprecedented paradigm shifts. The combination of lenvatinib plus pembrolizumab is now being evaluated as a front-line treatment in advanced HCC patients; early phase clinical trials have already reported promising results.Areas covered This paper reviews the combination of lenvatinib plus pembrolizumab for the treatment of advanced HCC. The preclinical rationale and completed and ongoing trials are examined and later, the authors reflect on biomarkers of predictive of response to immune-based combinations and future treatment decision-making on the basis of tolerability and clinical benefits provided by these novel therapeutics. A literature search was conducted in April 2021 of Pubmed/Medline, Cochrane library and Scopus databases; moreover, abstracts of international cancer meetings were reviewed.Expert opinion The landscape of new agents and combinations continues to expand. Recently, immune-based combinations have reported important results in advanced HCC, as witnessed by the landmark IMbrave150 trial. Based on the promising results of early phase clinical trials, lenvatinib plus pembrolizumab has the potential to represent a novel treatment option in this setting.Mesh repair of pelvic organ prolapse (POP) is complicated, causing erosions, postoperative pain and surgical failure. We hypothesised that reducing the mesh size and fixating it would result in significant cure rates and reduce complication rates. Here, we present the effectiveness of mini mesh implants in POP reconstruction. Sixty women who underwent repair of stage III and IV apical prolapse with cystocele or rectocele using skeletonised mesh implant Seratom PA MR MN® were evaluated. Anatomical outcomes were assessed using modified POP-quantification (POP-Q) staging and functional outcomes were self-reported by patients - one and three months post-operatively. Apical support with anterior and/or posterior colporrhaphy was performed, resulting in 96.6% success rate. Follow-up conducted one and three months post-operatively revealed significant improvement on the modified POP-Q (p  less then  .001) and no complaints of dyspareunia. Para-vesicular fixation using a skeletonised mini mesh implant is feasible and effective in POP repair and has low surgical complication risk.Impact StatementWhat is already known on this subject? Mesh repair for pelvic organ prolapse (POP) is currently under scrutiny as it may result in erosions, postoperative pain, and surgical failure.What do the results of this study add? The use of an apical support with mini-mesh implants resulted in a 96.6% (58/60) success rate and excellent outcomes at 1- and 3-month follow-up.What are the implications of these findings for clinical practice and/or further research? Reconstruction using skeletonised and fixated mini-mesh implants may be safe and effective for POP treatment.
Defibrotide (DF) is a polyribonucleotide with antithrombotic, pro-fibrinolytic, and anti-inflammatory effects on endothelium. These effects and the established safety of DF present DF as a strong candidate to treat viral and post-infectious syndromes involving endothelial dysfunction.

We discuss DF and other therapeutic agents that have the potential to target endothelial components of pathogenesis in viral and post-infectious syndromes. We introduce defibrotide (DF), describe its mechanisms of action, and explore its established pleiotropic effects on the endothelium. We describe the established pathophysiology of Coronavirus Disease 2019 (COVID-19) and highlight the processes specific to COVID-19 potentially modulated by DF. We also present influenza A and viral hemorrhagic fevers, especially those caused by hantavirus, Ebola virus, and dengue virus, as viral syndromes in which DF might serve therapeutic benefit. Finally, we offer our opinion on novel treatment strategies targeting endothelial dysfunction in viral infections and their severe manifestations.

Given the critical role of endothelial dysfunction in numerous infectious syndromes, in particular COVID-19, therapeutic pharmacology for these conditions should increasingly prioritize endothelial stabilization. NVP-TNKS656 Several agents with endothelial protective properties should be further studied as treatments for severe viral infections and vasculitides, especially where other therapeutic modalities have failed.
