Ticks are important vectors for different tick-borne viruses, some of which cause diseases and death in humans, livestock, and wild animals. Tick-borne encephalitis virus, Crimean-Congo hemorrhagic fever virus, Kyasanur forest disease virus, severe fever with thrombocytopenia syndrome virus, Heartland virus, African swine fever virus, Nairobi sheep disease virus, and Louping ill virus are just a few examples of important tick-borne viruses. The majority of tick-borne viruses have RNA genomes that routinely undergo rapid genetic modifications such as point mutations during their replication. These genomic changes can influence the spread of viruses to new habitats and hosts and lead to the emergence of novel viruses that can pose a threat to public health. https://www.selleckchem.com/products/act001-dmamcl.html Therefore, investigation of the viruses circulating in ticks is important to understand their diversity, host and vector range, and evolutionary history, as well as to predict new emerging pathogens. The choice of detection method is important, as most methods detect only those viruses that have been previously well described. On the other hand, viral metagenomics is a useful tool to simultaneously identify all the viruses present in a sample, including novel variants of already known viruses or completely new viruses. This review describes tick-borne viruses, their historical background of emergence, and their reemergence in nature, and the use of viral metagenomics for viral discovery and studies of viral evolution.Background Hospitalizations for complications related to opioid use disorder (OUD) are increasing. Hospitalists care for most hospitalized patients in the United States, yet little is known about their attitudes, beliefs, and clinical practices regarding OUD-related care. Methods We distributed an online survey to hospitalists in the United States to measure how access to addiction specialists affected attitudes and beliefs regarding hospital-based OUD care, OUD screening practices, naloxone prescribing, and buprenorphine initiation. Results Among 262 respondents, 67.9% (n = 178) reported having access to addiction specialists. While 84.5% (n = 221) reported often or always caring for patients with OUD, 48.2% (n = 126) rarely or never screened for OUD, 57.1% (n = 149) rarely or never prescribed or recommended naloxone as harm reduction, and 88.9% (n = 233) rarely or never initiated buprenorphine. In multivariable analyses, compared to hospitalists without access to addiction specialists, hospitalist with access to addiction specialists were more likely to feel supported to screen and refer patients to treatment (aOR = 4.4, 95% CI 2.1 - 9.1; ρ  less then  0.001), to be aware of local treatment resources (aOR = 3.4, 95% CI 1.8 - 6.3; ρ  less then  0.001), and refer patients to treatment (aOR = 3.0, 95% CI 1.7 - 5.6; ρ  less then  0.001). Conclusions Many hospitalists do not provide life-saving treatment to patients with OUD. Access to addiction specialists may increase provision of OUD-related care by hospitalists.Sexual transaction, or any exchange of financial or material goods for sex, contributes to the disproportionate HIV burden among young women aged 15-24 years in sub-Saharan Africa. We analysed representations of sexual transactions in a sample of 363 narratives about HIV written by young Africans. The narratives were written at 4 time points (1997, 2005, 2008, 2014) by authors aged 10-24 years in urban and rural areas of Senegal, Burkina Faso, South-east Nigeria, Kenya and Eswatini, formerly Swaziland. We combined three analytical approaches descriptive statistics of quantifiable characteristics of the narratives, thematic data analysis and a narrative-based approach. Representations reflect sexual transaction as a spectrum, with commercial sex work and sexual transactions that include romance at opposite ends. Narratives represent female characters increasingly motivated by a desire for social status symbols and by romantic love over time. Condemnation and stigmatisation of sexual transactions motivated by materialism remain similar across countries. In order to mitigate young women's disproportionate risk of HIV there is a need to combine efforts to address the economic marginalisation and gender inequality that drive sexual transactions with activities to promote skills and reflection and influence harmful norms, potentially drawing on companionate ideologies.In a sanctuary located on the island of Malta, 23 clinically healthy cats randomly selected were sampled for blood and fleas. Only fleas were collected from 35 cats. All fleas were identified as Ctenocephalides felis, except for one specimen of Ctenocephalides canis. To the best of the authors' knowledge, this may be the first time to establish the occurrence of Bartonella koehlerae and B. clarridgeiae, as well as of Candidatus Mycoplasma haemominutum in the blood samples of 11 cats (47.82% [95% CI 29.33-67.04]) with conventional PCR assays. One or more pathogens were found in 54 (96.42% [95% CI 86.74-99.70]) out of 56 pooled flea samples, the most prevalent was Rickettsia felis. The DNA of Bartonella henselae, the commonest etiological agent of cat scratch disease, was detected first time in a pooled flea sample of a cat.Brain donation in studies on aging remains a critical pathway to discovering and improving preventive measures and treatments for Alzheimer's dementia and related disorders. Brain donation for research is almost exclusively obtained from non-Latinx Whites of higher socioeconomic status in the United States. Despite persistent efforts, it has been difficult to obtain consent for brain donation among diverse participants. Hence, our understanding of Alzheimer's dementia and related disorders remains incomplete. The purpose of this methodological paper was to propose and outline a two-phase sequential mixed-methods research study design to identify barriers and facilitators of brain donation among diverse older adults. The first phase will consist of qualitative focus groups using a three (participant minority status African American, Latinx, or White of lower income) by two (participant brain donation decision consented or declined) design. The second phase will include statistical analyses of quantitative measures of existing data representing categories of variables that may be associated with decision making regarding brain donation.
