Neonatal sepsis refers to the systemic inflammatory response syndrome caused by various pathogens in newborns, ranking as the third leading cause of neonatal mortality globally. Meropenem is one of the most widely used broad-spectrum antibiotics in the treatment of neonatal sepsis. However, its irrational use has led to an increasingly serious problem of bacterial multidrug resistance. The Clinical Practice Guidelines for the Use of Meropenem in Treating Neonatal Sepsis (2024 Edition) provide 12 recommendations addressing 9 clinical issues, covering the timing of meropenem use, recommended dosage, prolonged infusion, monitoring and assessment, antibiotic adjustment strategies, treatment duration, and therapeutic strategies for carbapenem-resistant Enterobacteriaceae infections. These guidelines aim to provide evidence-based recommendations for the rational use of meropenem in neonatal sepsis patients. Professor Xiaomei Tong from the Department of Pediatrics at Peking University Third Hospital presented a detailed interpretation of the guidelines at the recent Fourth National Congress of the Chinese Medical Association for Bacterial and Fungal Infections (BISC 2024).

Urinary tract infections (UTIs) are commonly encountered in clinical practice, yet their treatment is not as straightforward as many assume. Professor Wenjie Yang  from the Department of Infectious Diseases at Tianjin City First Central Hospital begins with epidemiology, etiology, and resistance trends of UTIs, and emphasizes the principles and precautions of treating UTIs with oral antimicrobial agents. This discussion is highly beneficial for guiding clinical practice, and we share the insights below.

In recent years, the detection rate of carbapenem-resistant Gram-negative bacteria (CRO) in China has remained high, posing serious challenges to clinical treatments and patient outcomes. The limited therapeutic options have left many clinical needs unmet. At the recent Fourth National Conference on Bacterial and Fungal Infections organized by the Chinese Medical Association (BISC 2024), Professor Yunsong Yu from Zhejiang Provincial People's Hospital delivered a presentation titled "The Current Epidemic Situation and Challenges of Carbapenem-Resistant Organisms (CRO) Infections in China." Professor Yu detailed the prevalence and treatment status of CRO in China and explored the clinical challenges and strategies in depth.

Solid Organ Transplantation (SOT) is a crucial procedure for saving the lives of patients with end-stage organ failure. In recent years, the field of SOT has flourished in China, with significant improvements in the number of transplants and treatment outcomes. However, infections remain a critical factor affecting the survival and quality of life of SOT recipients. Among these, the incidence and mortality rates of invasive fungal diseases (IFD) are particularly high, especially among lung transplant recipients. At the recent 4th National Conference on Bacterial and Fungal Infections organized by the Chinese Medical Association (BISC 2024), the journal "Infection Medicine Today" had the opportunity to interview Professor Chunrong Ju from The First Affiliated Hospital of Guangzhou Medical University. Professor Ju shared her expert insights on the prevalence, current treatment landscape, and diagnostic challenges of IFD in SOT recipients, as well as discussed strategies for improving treatment outcomes through precision medicine.

As the incidence of syphilis continues to rise, clinicians are faced with an increasing number of patients with complex clinical presentations, posing significant challenges in patient management. At the 31st Conference on Retroviruses and Opportunistic Infections (CROI), Dr. Khalil Ghanem from the Johns Hopkins University School of Medicine delivered a keynote on the diagnosis and treatment of syphilis. In this issue of Infectious Disease Frontier, we are fortunate to have Dr. Ghanem discuss the diagnostic challenges of neurosyphilis, the value of the DoxyPEP prevention strategy, and the future outlook for syphilis management.

At the 31st Conference on Retroviruses and Opportunistic Infections (CROI 2024) held from March 3 to 6 in Denver, Colorado, USA, a study by Dr. Taisheng Li's team from the Peking Union Medical College Hospital was selected for a poster presentation and discussed at the fifth session. This conference, which started in 1993, has become one of the most influential meetings in the field of AIDS, attracting experts from around the world to share their latest research findings. The study presented by Dr. Li's team showcased a "Chinese solution" for addressing immune reconstitution deficiencies in HIV-infected individuals to the global academic community.

Patients who have successfully completed tuberculosis treatment still face a high risk of relapse, making the development of vaccines to prevent recurrent pulmonary tuberculosis an important direction in TB prevention efforts. At the recently concluded 31st Conference on Retroviruses and Opportunistic Infections (CROI 2024), a study presented as a late-breaking abstract (Abstract Number: 210) revealed that the novel tuberculosis vaccine H56:IC31, while not reducing the rate of TB relapse, enhanced both humoral and cellular immune responses in recipients. This marks the first clinical multicenter, randomized controlled trial (RCT) reported on the use of a TB vaccine for the prevention of relapse. The Infectious Disease Frontier has invited Dr. Shuihua Lu and his team from The Third People's Hospital of Shenzhen to introduce and comment on this study as follows.
