Abstract
Congenital cytomegalovirus (cCMV) infection carries a significant burden with a 0.64% global prevalence and a 17-20% chance of serious long-term effects in children. Since the last guidelines, our understanding, particularly regarding primary maternal infections, has improved. A cCMV guidelines group was convened under the patronage of the European Society of Clinical Virology in April 2023 to refine these insights. The quality and validity of selected studies were assessed for potential biases and the GRADE framework was employed to evaluate quality of evidence across key domains. The resulting recommendations address managing cCMV, spanning prevention to postnatal care. Emphasizing early and accurate maternal diagnosis through serological tests enhances risk management and prevention strategies, including using valaciclovir to prevent vertical transmission. The guidelines also strive to refine personalized postnatal care based on risk assessments, ensuring targeted interventions for affected families.

Abstract
Measles is a highly contagious viral illness that continues to cause significant mortality among young children worldwide despite the availability of a safe and effective vaccine. During the first half of 2019, over 182 countries reported more than 300,000 measles cases; greater than double the number from the same period in 2018. Timely recognition and laboratory confirmation of infected individuals as well as appropriate infection prevention measures are crucial to avert further transmission. This review highlights the importance of early recognition of the signs and symptoms of measles and provides details on the laboratory methods commonly employed to confirm cases, investigate outbreaks and characterize the virus. It's critical that clinicians, laboratorians and public health administrations work together to rapidly identify, confirm and contain the spread of measles globally.

Abstract
Human cytomegalovirus (CMV) remains one of the most important pathogens following solid-organ transplantation. Mounting evidence indicates that mammalian target of rapamycin (mTOR) inhibitors may decrease the incidence of CMV infection in solid-organ recipients. Here we aimed at elucidating the molecular mechanisms of this effect by employing a human CMV (HCMV) infection model in human macrophages, since myeloid cells are the principal in vivo targets of HCMV. We demonstrate a highly divergent host cell permissiveness for HCMV with optimal infection susceptibility in M2 but not M1 polarized macrophages. Employing an ultrahigh purified HCMV stock we observed rapamycin-independent viral entry and induction of IFN-β transcripts, but no proinflammatory cytokines or mitogen-activated protein kinases and mTOR activation early after infection. However, in the late infection phase, sustained mTOR activation was observed in HCMV-infected cells and was required for efficient viral protein synthesis including the viral late phase proteins pUL-44 and pp65. Accordingly, rapamycin strongly suppressed CMV replication 3 and 5 days postinfection in macrophages. In conclusion, these data indicate that mTOR is essential for virus replication during late phases of the viral cycle in myeloid cells and might explain the potent anti-CMV effects of mTOR inhibitors after organ transplantation.

Abstract
BACKGROUND Because poliomyelitis has been almost completely eradicated, Guillain-Barre syndrome (GBS) now accounts for most cases of acute flaccid paralysis. Understanding of the role of cytomegalovirus (CMV) in the pathogenesis of GBS is still very limited. METHODS We identified 42 CMV-seropositive patients with GBS between 1998 and 2001. Cerebrospinal fluid (CSF) and serum samples obtained from these patients were tested by CMV-specific polymerase chain reaction, and the glycoprotein B (gB) segment of the detected CMV genome was analyzed. Virological findings were compared with clinical characteristics and CSF laboratory values. RESULTS CMV DNA was detected in 13 (31%) of 42 CSF samples from patients with GBS but was not detected in 42 CSF samples from age-matched control subjects with acute encephalopathy. CSF samples obtained early after the onset of GBS were significantly more likely to be positive for CMV DNA (P=.048). gB1 was the most prevalent genotype detected in patients with GBS (88%), followed by gB3 (8%) and gB2 (4%). CONCLUSIONS CMV DNA was detected frequently in CSF samples from CMV-seropositive patients with GBS, especially early during the course of the disease. The clinical significance of this finding has yet to be elucidated, but early administration of antiviral therapy might prove to be beneficial for selected patients with GBS.
