Summary: Recent advances in immunosuppressive therapy have improved renal transplantation outcomes by reducing acute rejection incidence. BK virus nephropathy has emerged as a significant cause of graft dysfunction, progressing from viruria to viremia and associated nephropathy. Diagnosis of BK virus nephropathy involves histological examination and categorization of disease severity to guide treatment strategies.

Summary: This study describes the short-term kinetics of the antibody response in MPXV-infected patients during the 2022 multicountry outbreak. The results show that IgG, IgM, and IgA antibodies were detected as early as 4 days after symptom onset, while neutralizing antibodies were detectable after 1 week. There were no significant differences in antibody levels regardless of smallpox vaccination status, HIV positivity, or disease severity. Lower levels of IgM and IgG were observed in patients treated with antivirals.

Summary: Poliomavirus BK virus (BKV) is a highly infective virus that can cause asymptomatic infections. In renal transplanted recipients, BKV can lead to severe complications. Current treatments and prophylaxis options are limited, but increasing surveillance and early diagnosis show promise in improving outcomes.

Summary: The unprecedented Zika outbreak in the Americas from 2015-2016 led to global concern and accelerated the deployment of vaccine and therapeutic countermeasures. Several potent neutralizing antibodies against Zika and related flaviviruses have been discovered in recent years. Structure-based approaches have helped identify species-specific and cross-protective epitopes with therapeutic value.

Summary: BK polyomavirus-associated nephropathy can occur in kidney transplant recipients undergoing immunosuppressive treatment, and it is potentially linked to the development of renal cell carcinoma. This study analyzed gene expression profiles of renal biopsy samples and identified a gene cluster specifically upregulated in BK polyomavirus-associated nephropathy, which was associated with the prognosis of renal cell carcinoma.

Summary: Smallpox is an infectious disease caused by the variola virus, with a high mortality rate. Although smallpox was declared eradicated in 1980, the potential threat of bioterrorism has led to resumed research on the treatment and prevention of smallpox.

Summary: This study demonstrates that using red blood cells (RBCs) as carriers for adeno-associated virus (AAV) can improve its tissue-targeted transduction and enable repetitive administration. RBC-anchored AAVs show efficient transduction in the lungs and lead to enhanced target gene expression compared to free AAVs.

Summary: Pre-existing neutralizing antibodies to adeno-associated virus (AAV) may reduce the effectiveness of AAV-based therapies. A study on different pig strains showed that most pigs had a good response to AAV1, AAV5, AAV8, and AAV9, suggesting that these strains are suitable for gene therapy studies. Pre-screening for circulating AAV antibodies could be helpful before including pigs in studies.

Summary: This study demonstrates the nearly complete escape of XBB.1.5, CH.1.1, and CA.3.1 variants from neutralizing antibodies stimulated by mRNA vaccine or BA.4/5 wave infection, but neutralization can be rescued by a bivalent booster containing BA.5. CH.1.1 and CA.3.1 also show strong immune escape from monoclonal antibody S309. Furthermore, the spike proteins of XBB.1.5, CH.1.1, and CA.3.1 exhibit enhanced fusogenicity and processing compared to BA.2.

Summary: The study developed a peptide enzyme-linked immunosorbent assay (pELISA) as a possible alternative to the neutralization test for evaluating the immune response to IBV vaccine. The pELISA could indirectly evaluate neutralizing antibody titers against different types of IBV in all tested sera, with a coefficient of 0.83 for neutralizing antibody titers. The pELISA has the potential to detect antibodies against different types of IBV in all tested sera and surveillance the infection of IBV.

Summary: This study investigates the role of the MICA gene in a French multicenter cohort of kidney transplants and finds that MICA mismatches are associated with decreased graft survival. Both before and after transplantation, anti-MICA donor-specific antibodies are strongly associated with increased antibody-mediated rejection. This effect is synergetic with anti-HLA DSA. De novo-developed anti-MICA DSA are the most harmful and associated with reduced graft survival. Evaluation of MICA matching and immunization is warranted for identifying high-risk transplant rejection and loss.

Summary: This study presents a framework that combines epidemiological and machine learning models to predict the risk of ICU treatment for individuals infected with COVID-19. Simulation results based on French data show that policies considering clinical risk predictions can relax isolation restrictions earlier without overwhelming the ICU capacity.

Summary: About 10% of people infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) experience post COVID-19 disease. This study analyzed data from a French disease cohort and found that among patients symptomatic after 2 months, 85% still reported symptoms one year after their symptom onset. Symptoms showed different trends over time, with some decreasing, some remaining stable, and some increasing in prevalence. The study provides important insights into the natural history of post COVID-19 disease.

Summary: This study presents graphical methods to group interventions and uses conjoint analysis to place weights on outcomes based on stakeholders' preferences. The results provide valuable information about the clustering of interventions. Grouping interventions helps decision makers identify optimal options in terms of benefit-risk balance and choose interventions from the best cluster based on other factors such as cost and implementation.

Summary: Ingestion of food or water contaminated with pathogenic bacteria can lead to serious diseases. The One Health approach is important in preventing the spread of diseases between animals, humans, and the environment, especially antibiotic-resistant bacteria. Bacteriophages have gained importance as effective alternatives for treating bacterial diseases and ensuring food safety.

Summary: In the past decade, it has become common practice to provide rapid answers and early patient access to innovative treatments in the absence of randomized clinical trials. This trend is particularly important in oncology when evaluating new targeted therapies. This article provides guidelines for the critical appraisal of comparisons or conducting single-arm trials, using the example of ciltacabtagene autoleucel for the treatment of relapsed or refractory multiple myeloma.

Summary: The preferred approach to compare two treatments is a randomized controlled trial (RCT) which ensures similarity between groups and allows causal conclusions. When RCTs are not possible, observational data can be used to infer treatment effectiveness under certain assumptions, using regression modeling or propensity score methods. Target trial emulation principles are also discussed.

Summary: Exome sequencing of a patient with postchemotherapy thymic teratoma revealed 19 shared somatic mutations among the mature teratoma, melanocytic neuroectodermal tumor (MNT), and metastatic anaplastic MNT components. Enrichment analysis indicated the involvement of known cancer-related genes such as KRAS, TP53, ERBB4, and KDR in the development of anaplastic MNT transformation. This study provides valuable insights into the molecular characteristics of MNT and highlights the importance of understanding these tumors for improved therapeutics.

Summary: Tick-borne encephalitis (TBE) is caused by the tick-borne encephalitis virus (TBEV) transmitted by infected Ixodes ricinus ticks. TBEV-Eu is endemic in 27 European countries, and there has been an increase in TBE incidence, even in countries with low endemicity. Children with TBE may experience severe forms and long-term cognitive impairment. This review comprehensively describes TBEV incidence, transmission routes, clinical manifestations, imaging findings, and long-term outcomes in children, as well as vaccination recommendations in European countries.
