01). In the W&S group, patients treated with PCV at first relapse had a longer PFS from intervention than those treated with TMZ (7.2 vs 4.0 years, p = 0.04). Multivariate analysis identified smaller tumor volume prior to any intervention (p = 0.02) to be prognostic for PFS. PCV chemotherapy alone is an effective treatment for WHO grade 2 oligodendroglioma, with long PFS and low rate of histological progression.PCV chemotherapy alone is an effective treatment for WHO grade 2 oligodendroglioma, with long PFS and low rate of histological progression.African American women are disproportionately impacted by breast cancer, including triple-negative disease, at a young age. Yet most public health research in breast cancer focuses on women of screening age. This study identified the specific breast cancer educational needs of African American women below the recommended screening age. Data were collected through 30 key informant interviews with young African American women breast cancer survivors (diagnosed between 18 and 45), family members of African American women diagnosed between 18-45 years, and community organization leaders and healthcare providers who work with young African American women impacted by breast cancer. Data were coded and analyzed by multiple team members using template analysis. The analysis identified four overarching themes reflecting breast cancer educational needs of young African American women. Although most Breast Cancer Knowledge and Perceived Risk educational needs were consistent with those of older women, there were specific needs involving Cultural Reluctance in Health Disclosures and Breast Cancer Risk Reduction. With regard to Healthcare Provider Relationships, participants stated a need for younger women to be particularly proactive in advocating for their health, as providers may be dismissive about cancer concerns due to young age. Though breast cancer in younger women is statistically improbable, there are educational needs specific to young African American women involving self-advocacy and family history. Findings have implications for developing interventions guiding young women to advocate for themselves in medical encounters and in their families, as well as for teaching medical providers how to counsel the young women regarding breast cancer.In this study, we examined endophytic fungi in leaves of Mandevilla catimbauensis, an endemic plant species found in the Brazilian dry forest (Caatinga), and endophytic fungi's potential to produce L-asparaginase (L-ASNase). In total, 66 endophytes were isolated, and the leaf-fragment colonisation rate was 11.78%. Based on morphology, internal transcribed spacer (ITS), and partial large subunit (LSU) of ribosomal DNA sequencing, the endophytic fungi isolated belonged to six Ascomycota orders (Botryosphaeriales, Capnodiales, Diaporthales, Eurotiales, Marthamycetales, and Pleosporales). Phyllosticta species were the most frequent endophytes isolated (23 isolates [45.1%] from two species). The Shannon-Wiener and Fisher alpha index average values were 0.56 and 3.26, respectively. Twenty endophytes were randomly selected for the L-ASNase production test, of which fourteen isolates showed potential to produce the enzyme (0.48-2.22 U g-1), especially Phyllosticta catimbauensis URM 7672 (2.22 U g-1) and Cladosporium sp. G45 (2.11 U g-1). Phyllosticta catimbauensis URM 7672 was selected for the partial optimisation of L-ASNase production because of its ability to generate considerable amounts of enzyme. We obtained the highest L-ASNase activity (3.47 U g-1), representing an increase of 36.02% in enzymatic production, under the following experimental conditions a pH of 4.2, 1.0% inoculum concentration, and 2.5% L-asparagine concentration. Our study showed that M. catimbauensis harbours an important diversity of endophytic fungi with biotechnological potential for L-ASNase production.The global COVID-19 pandemic continues to claim victims worldwide, representing a health and socioeconomic challenge with few precedents in human history. The therapeutic agents used to treat COVID-19 infection are mostly aimed at avoiding the most serious complications and organ damage that in a percentage of cases can be fatal. Recently, the first COVID-19 vaccines have been authorised, starting a massive vaccination campaign worldwide. The COVID-19 vaccines authorized or under testing use different methods of action such as mRNA, DNA vaccine, viral vector, protein subunit, and virus inactivated immunization strategies. The mRNA vaccines are the first authorised vaccines with this new method of action, initiating a new era of preventive medicine. To date, data indicate that they may be effective against the newly identified SARS-CoV-2 variants. Short-term studies indicated an acceptable safety profile but long-term immunity as well as safety is not yet available. In this article, we briefly describe mRNA vaccines and highlight some aspects yet to be fully defined.The hyper-IgE syndromes (HIES) are a heterogeneous group of inborn errors of immunity sharing manifestations including increased infection susceptibility, eczema, and raised serum IgE. Since the prototypical HIES description 55 years ago, areas of significant progress have included description of key disease-causing genes and differentiation into clinically distinct entities. The first two patients reported had what is now understood to be HIES from dominant-negative mutations in signal transduction and activator of transcription 3 (STAT3-HIES), conferring a broad immune defect across both innate and acquired arms, as well as defects in skeletal, connective tissue, and vascular function, causing a clinical phenotype including eczema, staphylococcal and fungal skin and pulmonary infection, scoliosis and minimal trauma fractures, and vascular tortuosity and aneurysm. Due to the constitutionally expressed nature of STAT3, initial reports at treatment with allogeneic stem cell transplantation were not positive and treatment has hinged on aggressive antimicrobial prophylaxis and treatment to prevent the development of end-organ disease such as pneumatocele. Elenbecestat in vivo Research into the pathophysiology of STAT3-HIES has driven understanding of the interface of several signaling pathways, including the JAK-STAT pathways, interleukins 6 and 17, and the role of Th17 lymphocytes, and has been expanded by identification of phenocopies such as mutations in IL6ST and ZNF341. In this review we summarize the published literature on STAT3-HIES, present the diverse clinical manifestations of this syndrome with current management strategies, and update on the uncertain role of stem cell transplantation for this disease. We outline key unanswered questions for further study.
