Review
Antiviral drugs are a cornerstone in the first line of antiviral therapy and their demand rises consistently with increments in viral infections and successive outbreaks. The drugs enter the waters due to improper disposal methods or via human excreta following their consumption; consequently, many of them are now classified as emerging pollutants. Hereby, we review the global dissemination of these medications throughout different water bodies and thoroughly investigate the associated risk they pose to the aquatic fauna, particularly our vertebrate relative fish, which has great economic and dietary importance and subsequently serves as a major doorway to the human exposome. Our risk assessment identifies eleven such drugs that presently pose high to moderate levels of risk to the fish. The antiviral drugs are likely to induce oxidative stress, alter the behaviour, affect different physiological processes and provoke various toxicological mechanisms. Many of the compounds exhibit elevated bioaccumulation potential, while, some have an increased tendency to leach through soil and contaminate the groundwater. Eight antiviral medications show a highly recalcitrant nature and would impact the aquatic life consistently in the long run and continue to influence the human exposome. Thereby, we call for urgent ecopharmacovigilance measures and modification of current water treatment methods.

The volume of public proteomics data is rapidly increasing, causing a computational challenge for large-scale reanalysis. Here, we introduce quantms ( https://quant,ms.org/ ), an open-source cloud-based pipeline for massively parallel proteomics data analysis. We used quantms to reanalyze 83 public ProteomeXchange datasets, comprising 29,354 instrument files from 13,132 human samples, to quantify 16,599 proteins based on 1.03 million unique peptides. quantms is based on standard file formats improving the reproducibility, submission and dissemination of the data to ProteomeXchange.

This review identifies which elements of home-based comprehensive sexual health care (home-based CSH) impacted which key populations, under which circumstances. A realist review of studies focused on home-based CSH with at least self-sampling or self-testing HIV and additional sexual health care (e.g., treatment, counseling). Peer-reviewed quantitative and qualitative literature from PubMed, Embase, Cochrane Register of Controlled Trials, and PsycINFO published between February 2012 and February 2023 was examined. The PRISM framework was used to systematically assess the reach of key populations, effectiveness of the intervention, and effects on the adoption, implementation, and maintenance within routine sexual health care. Of 730 uniquely identified records, 93 were selected for extraction. Of these studies, 60% reported actual interventions and 40% described the acceptability and feasibility. Studies were mainly based in Europe or North America and were mostly targeted to MSM (59%; 55/93) (R). Overall, self-sampling or self-testing was highly acceptable across key populations. The effectiveness of most studies was (expected) increased HIV testing. Adoption of the home-based CSH was acceptable for care providers if linkage to care was available, even though a minority of studies reported adoption by care providers and implementation fidelity of the intervention. Most studies suggested maintenance of home-based CSH complementary to clinic-based care. Context and mechanisms were identified which may enhance implementation and maintenance of home-based CSH. When providing the individual with a choice of testing, clear instructions, and tailored dissemination successful uptake of STI and HIV testing may increase. For implementers perceived care and treatment benefits for clients may increase their willingness to implement home-based CSH. Therefore, home-based CSH may determine more accessible sexual health care and increased uptake of STI and HIV testing among key populations.

Review
Much of the fatality of tumors is linked to the growth of metastases, which can emerge months to years after apparently successful treatment of primary tumors. Metastases arise from disseminated tumor cells (DTCs), which disperse through the body in a dormant state to seed distant sites. While some DTCs lodge in pre-metastatic niches (PMNs) and rapidly develop into metastases, other DTCs settle in distinct microenvironments that maintain them in a dormant state. Subsequent awakening, induced by changes in the microenvironment of the DTC, causes outgrowth of metastases. Hence, there has been extensive investigation of the factors causing survival and subsequent awakening of DTCs, with the goal of disrupting these processes to decrease cancer lethality. We here provide a detailed overview of recent developments in understanding of the factors controlling dormancy and awakening in the lung, a common site of metastasis for many solid tumors. These factors include dynamic interactions between DTCs and diverse epithelial, mesenchymal, and immune cell populations resident in the lung. Paradoxically, among key triggers for metastatic outgrowth, lung tissue remodeling arising from damage induced by the treatment of primary tumors play a significant role. In addition, growing evidence emphasizes roles for inflammation and aging in opposing the factors that maintain dormancy. Finally, we discuss strategies being developed or employed to reduce the risk of metastatic recurrence.

This section explores the challenges involved in translating genomic research into genomic medicine. A number of priorities have been identified in the Australian National Health Genomics Framework for addressing these challenges. Responsible collection, storage, use and management of genomic data is one of these priorities, and is the primary theme of this section. The recent release of Genomical, an Australian data-sharing platform, is used as a case study to illustrate the type of assistance that can be provided to the health care sector in addressing this priority. The section first describes the National Framework and other drivers involved in the move towards genomic medicine. The section then examines key ethical, legal and social factors at play in genomics, with particular focus on privacy and consent. Finally, the section examines how Genomical is being used to help ensure that the move towards genomic medicine is ethically, legally and socially sound and that it optimises advances in both genomic and information technology.

Review
The 4th Italian Zebrafish Meeting took place in Palermo from February 7 to 9, 2024. The primary aim of this meeting was to bring together a diverse group of principal investigators, young researchers, facility managers, commercial vendors, and others to provide an important forum for presentation and discussion of the most innovative and exciting scientific research currently ongoing in Italy using the zebrafish model. Nonetheless, the meeting program has been conceived to allow the dissemination of cutting-edge scientific research across a wide range of topics and to shed light on its future directions, without geographical boundaries. Indeed, people from various parts of the world joined the meeting, and 210 participants presented their latest work in talks and posters. Importantly, the meeting had designated time to foster open scientific exchange and informal networking opportunities among participants of all career stages, thus allowing initiation of new collaborations and strengthening of existing partnerships. The meeting was a tremendous success as testified by the highest participation ever since the first meeting of the series in 2017, coupled with the highly positive satisfaction rating expressed by the attendants. The full program and detailed information about the meeting can be found on the dedicated website at https://itazebrafishmeeting.wixsite.com/izm2024.

The transcriptional regulation of the horizontally acquired iron uptake system, yersiniabactin and its contribution to oxidative stress tolerance and pathogenicity of globally emerging strains.
The bacterial species () is a highly diverse pathogen containing more than 2600 distinct serovars, which can infect a wide range of animal and human hosts. Recent global emergence of multidrug resistant strains, from serovars Infantis and Muenchen is associated with acquisition of the epidemic megaplasmid, pESI that augments antimicrobial resistance and pathogenicity. One of the main pESI's virulence factors is the potent iron uptake system, yersiniabactin encoded by , and gene cluster. Here we show that yersiniabactin, has an underappreciated distribution among different serovars and subspecies, integrated in their chromosome or carried by different conjugative plasmids, including pESI. While the genetic organization and the coding sequence of the yersiniabactin genes are generally conserved, a 201-bp insertion sequence upstream to , was identified in pESI. Despite this insertion, pESI-encoded yersiniabactin is regulated by YbtA and the ancestral Ferric Uptake Regulator (Fur), which binds directly to the and promoters. Furthermore, we show that yersiniabactin genes are specifically induced during the mid-late logarithmic growth phase and in response to iron-starvation or hydrogen peroxide. Concurring, yersiniabactin was found to play a previously unknown role in oxidative stress tolerance and to enhance intestinal colonization of . Infantis in mice. These results indicate that yersiniabactin contributes to fitness and pathogenicity and is likely to play a role in the rapid dissemination of pESI among globally emerging lineages.

The exponential increase in the number of submissions, further accelerated by generative AI, and the decline in the availability of experts are burdening the peer review process. This has led to high unethical desk rejection rates, a growing appeal for the publication of unreviewed preprints, and a worrying proliferation of predatory journals. The idea of monetarily compensating peer reviewers has been around for many years; maybe, it is time to take it seriously as one way to save the peer review process. Here, I argue that paying reviewers, when done in a fair and transparent way, is a viable solution. Like the case of professional language editors, part-time or full-time professional reviewers, managed by universities or for-profit companies, can be an integral part of modern peer review. Being a professional reviewer could be financially attractive to retired senior researchers and to researchers who enjoy evaluating papers but are not motivated to do so for free. Moreover, not all produced research needs to go through peer review, and thus persuading researchers to limit submissions to their most novel and useful research could also help bring submission volumes to manageable levels. Overall, this paper reckons that the problem is not the peer review process per se but rather its function within an academic ecosystem dominated by an unhealthy culture of 'publish or perish'. Instead of reforming the peer review process, academia has to look for better science dissemination schemes that promote collaboration over competition, engagement over judgement, and research quality and sustainability over quantity.

T-cell prolymphocytic leukemia (T-PLL) presents unique treatment challenges because of its rarity and aggressiveness. Allogeneic hematopoietic stem cell transplantation offers a potentially curative option, but its safety in patients with concurrent invasive fungal infections and solid malignancies remains uncertain. We present a case of a 68-year-old male with T-PLL who developed disseminated cryptococcal disease with prostate involvement and concurrent prostate cancer (PCa). Despite the challenges, successful control of the infection and radical prostatectomy enabled the patient to proceed safely to allogeneic transplantation. The case highlights the importance of vigilance for unusual infections, such as Cryptococcus, in immunocompromised patients presenting with lower urinary tract symptoms. Clinicians should consider the possibility of PCa in this population, particularly in the context of chronic leukemia. Concurrently, the potential association between fungal prostate infections and PCa warrants further investigation.

This case report investigates the management of a 24-week-old neonate with congenital cytomegalovirus (CMV) infection and its sequelae, including severe intrauterine growth restriction, thrombocytopenia, and brain anomalies, ultimately progressing to lissencephaly. The diagnostic challenges included delayed clinical suspicion of congenital CMV, which was not identified until after delivery through CMV DNA polymerase chain reaction, and differentiating its symptoms from other potential causes of the neonate's condition. Aggressive interventions included antibiotics, antiviral therapy with ganciclovir, and supportive measures such as intubation, CPR, respiratory support, blood transfusions, and management of coagulopathy. Despite these efforts, the patient deteriorated due to progressive hypoperfusion, hypoxemic cardiorespiratory failure, and disseminated intravascular coagulopathy. Due to the poor prognosis and extent of multiorgan damage, support was withdrawn per parental consent. This case highlights the complications encountered when managing an advanced-stage neonatal CMV infection and emphasizes the importance of a multidisciplinary and holistic approach to guide diagnosis and treatment.
