PURPOSE OF REVIEW: This review comments on the current guidelines for the treatment of wound infections under definition of acute bacterial skin and skin structure infections (ABSSSI). However, wound infections around a catheter, such as driveline infections of a left ventricular assist device (LVAD) are not specifically listed under this definition in any of the existing guidelines. RECENT FINDINGS: Definitions and classification of LVAD infections may vary across countries, and the existing guidelines and recommendations may not be equally interpreted among physicians, making it unclear if these infections can be considered as ABSSSI...

PURPOSE OF REVIEW: This article reviews recently published research on sexual health challenges and HIV and sexually transmitted infections (STIs) among migrant, immigrant and displaced people (MIDP) worldwide. We aimed to identify current evidence gaps regarding HIV/STI epidemiology, sexual health needs and interventions. RECENT FINDINGS: Incidence and prevalence of HIV, hepatitis B virus, hepatitis C virus and syphilis were higher among MIDP compared to host populations...

PURPOSE OF REVIEW: Community engagement is key to the success of sustainable public health interventions. This review highlights recent published studies that describe the use of community-engaged methods in sexually transmitted infection (STI) prevention research. RECENT FINDINGS: We organized the findings using a socio-ecological model. At the individual level, communities were engaged through participation in formative research, short-term consultations and community advisory board participation, as well as co-creation activities...

PURPOSE OF REVIEW: While effective vaccines to prevent invasive infections by Neisseria meningitidis have been deployed around the world, development of a vaccine to prevent Neisseria gonorrhoeae has lagged. After multiple failed vaccine candidates, vaccine development for N. gonorrhoeae is showing promise for the first time in several decades. This review highlights recent progress in the field. RECENT FINDINGS: Vaccines containing outer-membrane vesicles (OMV) have been used to manage outbreaks of the serogroup B N...

PURPOSE OF REVIEW: The early recognition of acute bacterial skin infections (ABSIs) and their swift and adequate care are the major determinants of success. The features that can hamper or delay surgical and medical management can lead to 'difficult-to-treat' ABSIs. RECENT FINDINGS: Delayed diagnosis and belated management are the key obstacles to be overcome. Clinicians should be careful about underestimating the severity of ABSIs and overlooking comorbidities, especially immunosuppression...

PURPOSE OF REVIEW: To update the management of severe Acinetobacter baumannii infections (ABI), particularly those caused by multi-resistant isolates. RECENT FINDINGS: The in vitro activity of the various antimicrobial agents potentially helpful in treating ABI is highly variable and has progressively decreased for many of them, limiting current therapeutic options. The combination of more than one drug is still advisable in most circumstances. Ideally, two active first-line drugs should be used...

PURPOSE OF REVIEW: The aim of this narrative review is to compare the prognostic utility of the new definition of difficult-to-treat resistance (DTR) vs. established definitions in patients with Pseudomonas aeruginosa infection to understand the therapeutic implications of resistance classification and its impact on clinical outcome. RECENT FINDINGS: Among Gram-negative bacteria (GNB), P. aeruginosa (PA) is associated with high rates of morbidity and mortality, mostly related to its intrinsic capacity of developing antibiotic resistance...

PURPOSE OF REVIEW: This article aims to review the epidemiology of nonfermenting Gram-negative bacilli (NFGNB) based on recent literature reports, particularly, of the less common, but with emerging clinical significance species. RECENT FINDINGS: The reported frequency of multidrug-resistant Acinetobacter baumannii and Pseudomonas aeruginosa is increasing, with very significant variability, however, between different countries. Apart from the major NFGNB, that is, A...

PURPOSE OF REVIEW: Serious infections caused by nonfermenting Gram-negative bacteria (NF-GNB) pose a significant challenge for clinicians due to the limited treatment options available, which are frequently associated with issues of toxicity and unfavourable pharmacokinetic profiles. The aim of this review is to provide a brief overview of the existing data concerning the ongoing development of antiinfective agents targeting NF-GNB. RECENT FINDINGS: Several agents exhibiting efficacy against NF-GNB are under clinical investigation...

PURPOSE OF REVIEW: Stenotrophomonas maltophilia is an emerged opportunistic pathogen. Intrinsic multidrug resistance makes treating infections caused by S. maltophilia a great clinical challenge. Herein, we provide an update on the most recent literature on treatment options for severe S. maltophilia infections. RECENT FINDINGS: Trimethoprim-sulfamethoxazole (SXT) is recognized as the first-line therapy for S. maltophilia infections. However, its clinical use is based on good in vitro activity and favorable clinical outcomes, rather than on solid minimum inhibitory concentration (MIC) correlations with pharmacokinetic/pharmacodynamics (PK/PD) and/or clinical outcomes...

PURPOSE OF REVIEW: Respiratory syncytial virus (RSV) remains a leading cause of mortality and morbidity worldwide. RSV seasonality was disrupted by COVID-19-associated nonpharmaceutical interventions (NPIs). We review RSV seasonality, molecular epidemiology, clinical manifestations, and community awareness to inform future prevention strategies. RECENT FINDINGS: An initial reduction of RSV disease observed with NPIs, and subsequent global resurgence was associated with a collapse in genetic diversity...

PURPOSE OF REVIEW: This review focuses on the management of severe Pseudomonas aeruginosa infections in critically ill patients. RECENT FINDINGS: Pseudomonas aeruginosa is the most common pathogen in intensive care; the main related infections are nosocomial pneumonias, then bloodstream infections. Antimicrobial resistance is common; despite new antibiotics, it is associated with increased mortality, and can lead to a therapeutic deadlock. SUMMARY: Carbapenem resistance in difficult-to-treat P...

PURPOSE OF REVIEW: Cytomegalovirus (CMV) is a driver of negative patient and allograft outcomes after solid organ transplantation (SOT) and new tools are needed to circumvent these outcomes. We will review key elements of CMV antiviral stewardship in SOT, discuss the available evidence for CMV antiviral stewardship programs and feature areas for expansion in the current landscape of CMV management. RECENT FINDINGS: CMV remains a common complication after SOT. While consensus guidelines provide recommendations for the prevention and treatment of CMV, a one-size-fits-all approach is not necessarily appropriate for all unique patients and posttransplant courses, types of SOT recipients and transplant centers...

PURPOSE OF REVIEW: Letermovir has changed the game of primary prophylaxis against cytomegalovirus (CMV) for hematopoietic stem cell transplant (HSCT) and more recently, solid organ transplant recipients. This is largely due to letermovir's similar efficacy in protecting against CMV reactivation and disease, along with its superior safety profile, notably reduced myelotoxicity, and lack of renal dose adjustment compared to standard agents like valganciclovir. This review will describe the potential benefits and clinical considerations of letermovir as prophylaxis among transplant recipients, with a focus on recent evidence describing nonviral outcomes of CMV...

PURPOSE OF REVIEW: In the present narrative review, we discuss the characteristics and differences between the Infectious Diseases Society of America (IDSA) and European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines in terms on their recommendations/suggestions for the treatment of Pseudomonas aeruginosa and Acinetobacter baumannii infections. RECENT FINDINGS: Treatment of severe infections caused by nonfermenting gram-negative bacteria (NF-GNB) is posing both novel hopes and novel challenges to physicians worldwide, and both the IDSA and the ESCMID have recently updated/released their guidelines or guidance documents, based on different philosophies and providing recommendations for the treatment of NF-GNB infections...

PURPOSE OF REVIEW: This review aims to discuss the current state of surgical antimicrobial prophylaxis (SAP) evidence for surgical site infection prevention. Despite decades of research, knowledge gaps persist in identifying optimal SAP regimens. RECENT FINDINGS: Recent randomised controlled trials highlight ongoing heterogeneity in study design. Key new findings support the use of oral preoperative SAP for colorectal surgery and advise against the use of SAP for transperineal prostate biopsy...

PURPOSE OF REVIEW: This review will describe role of shorter antibiotic therapies, early switch from intravenous to oral therapy, and artificial intelligence in infectious diseases. RECENT FINDINGS: There is evidence that shorter courses of antibiotics are noninferior to standard durations of therapy. This has been demonstrated with Enterobacterales bacteremia that can be treated with 7 days of therapy, community acquired pneumonia with 3 days and ventilator associated pneumonia with just 7 days of antibiotic therapy...

PURPOSE OF REVIEW: Mucormycosis (MCR) is a common opportunistic mold infection, and Mucorales were recently designated by WHO as priority pathogens. The interest in this infection has risen significantly since the major outbreak of MCR in the context of the COVID-19 pandemic, particularly in India. Herein, we summarize recently (last 24 months) published information regarding clinical aspects of MCR. RECENT FINDINGS: The disease remains protean in its clinical presentation, difficult to diagnose, and challenging to treat...

PURPOSE OF REVIEW: Although invasive mold infections (IMI) are a major complication in high-risk populations, treatment duration has not yet been well defined. RECENT FINDINGS: Guidelines suggest documenting clinical/radiological resolution and immunological recovery before stopping antifungal treatment, after a minimum duration of treatment of 3 months for invasive pulmonary aspergillosis, while longer (up to 6 months) duration is proposed for the treatment of invasive mucormycosis...
