If approved by regulatory agencies in case of favorable results from ongoing (and, for some agents, already completed) phase-3 studies, some novel β-lactam/β-lactamase inhibitor (BL/BLI) combinations could become available in the next few years as additional important options for treating MBL-producing CR-GNB infections.

Low and sub microscopic infections are increasingly documented but remain hard to diagnose with current point-of-care tests, and their contribution to morbidity and transmission are unclear. Artemether-lumefantrine has been endorsed for treatment in first trimester, but many women attend antenatal clinics later in pregnancy, and reaching high-risk young, first-time mothers is particularly difficult. Small-for-gestational-age babies frequently result from malaria, which affects the placenta's development and its functions such as nutrient transport. Resistance to continues to increase to sulphadoxine-pyrimethamine, the mainstay of intermittent preventive treatment in pregnancy. The alternative, dihydroartemisinin-piperaquine controls malaria better, but does not improve pregnancy outcomes, suggesting that sulphadoxine-pyrimethamine may have nonmalarial effects including improving gut function or reducing dangerous inflammation. Understanding of how the malaria parasite uses the VAR2CSA protein to bind to its placental receptor is increasing, informing the search for a vaccine to prevent pregnancy malaria.Summary: Progress in several areas increases optimism that improved prevention and control of malaria in pregnancy is possible, but obstacles remain.","PeriodicalId":10880,"journal":{"name":"Current Opinion in Infectious Diseases","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141626263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we discuss the recent developments in the understanding of immune mechanisms that lead to severe dengue and the learnings from the past, that can help us to find therapeutic targets, prognostic markers, and vaccines to prevent development of severe disease.Recent findings: The extent and duration of viraemia often appears to be associated with clinical disease severity but with some variability. However, there also appear to be significant differences in the kinetics of viraemia and nonstructural protein 1 (NS1) antigenemia and pathogenicity between different serotypes and genotypes of the DENV. These differences may have significant implications for development of treatments and in inducing robust immunity through dengue vaccines. Although generally higher levels of neutralizing antibodies are thought to protect against infection and severe disease, there have been exceptions and the specificity, breadth and functionality of the antibody responses are likely to be important.Summary: Although there have been many advances in our understanding of dengue pathogenesis, viral and host factors associated with occurrence of severe dengue, vascular leak and the immune correlates of protection remain poorly understood.","PeriodicalId":10880,"journal":{"name":"Current Opinion in Infectious Diseases","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141855097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review will describe the risk and consequences of postnatal CMV infection among very preterm infants.Recent findings: Postnatal CMV may manifest as clinically silent infection or as mild to severe and occasionally fatal disease. The risk of disease is balanced by the health benefits of human milk feeding to preterm infants. Postnatal CMV infection has been associated with increased risks of multiple preterm morbidities such as bronchopulmonary dysplasia, necrotizing enterocolitis and neurodevelopmental impairment, but current evidence is limited by the selection bias inherent to reporting in case series and retrospective cohort studies.Summary: Knowledge gaps exist regarding the risk-benefit balance of pasteurization to inactivate CMV in fresh breast milk, as well as the optimal dosing, duration and efficacy of treating infected infants with antiviral medications. Multicenter, prospective studies are urgently needed to accurately determine the true burden that postnatal CMV infection presents to very preterm infants.
