HIV viral suppression and retention in care are critically important outcomes requiring successful continuous patient engagement. However, barriers to such engagement are complex and require innovative solutions. AREAS COVERED: A multistakeholder group of experts comprising clinicians and service delivery researchers assembled to clarify what constitutes engagement in HIV care and identify overarching themes that inform strategies in this field. This article captures this expert opinion and adds relevant literature on selected current best practices. EXPERT OPINION: The multistakeholder group felt strongly that a better understanding of the facilitators of continuous care engagement was critical. Unlike 'retention in care,' 'engagement in care' for an individual is nuanced, flexible, evolves and requires ongoing communication between patients, providers, and other key stakeholders. The following approaches highlight care engagement strategies at different stakeholder levels: 1) patient-level: personalized care and incentivization; 2) clinic-level: wraparound, co-localized, patient-centered low-barrier care, a diverse multidisciplinary team, patient support networks, and expanded use of telemedicine; 3) healthcare system-level: utilization of external partnerships. We propose a series of diverse and complementary approaches based on a more nuanced understanding of the qualitative aspects of engagement in care.

While acute UTIs can usually be effectively treated, recurrent UTIs (rUTIs) impact patients for years, causing significant morbidity and can become refractory to front-line antibiotics. AREAS COVERED: This review discusses the risk factors associated with rUTI, current rUTI treatment paradigms, prophylactic strategies, and challenges in rUTI diagnostics. We specifically discuss common risk factors for rUTI, including biological sex, age, menopause status, and diabetes mellitus. We also review recently available evidence for commonly used treatments, from oral antibiotic therapy to intravesical antimicrobials, electrofulguration of chronic cystitis, and the last-resort treatment, cystectomy. We discuss the most current literature evaluating prophylactic strategies for rUTI including long-term antibiotic prophylaxis, estrogen hormone therapy, and dietary supplements. Finally, we address the important role of UTI diagnostics in effective rUTI management and review the strengths and limitations of both current and emerging UTI diagnostic platforms as well as their ability to operate at point-of-care. EXPERT OPINION: We discuss the current challenges faced by clinicians in managing rUTI in women and the steps that should be taken so that clinicians, scientists, and patients can work together to better understand the disease and develop better strategies for its management.

Due to the high prevalence rates of carbapenem- and extensively drug-resistant (CR, XDR) phenotypes, limited antibiotic options are available for the effective treatment of pneumonia caused by CR/XDR-Abc. AREAS COVERED: In vitro susceptibility data, relevant pharmacokinetic profiles (especially the penetration ratios from plasma into epithelial-lining fluid), and pharmacodynamic indices of key antibiotics against CR/XDR-Abc are reviewed. EXPERT OPINION: Doubling the routine intravenous maintenance dosages of conventional tigecycline (100 mg every 12 h) and minocycline (200 mg every 12 h) might be recommended for the effective treatment of pneumonia caused by CR/XDR-Abc. Nebulized polymyxin E, novel parenteral rifabutin BV100, and new polymyxin derivatives (SPR206, MRX-8, and QPX9003) could be considered supplementary combination options with other antibiotic classes. Regarding other novel antibiotics, the potency of sulbactam-durlobactam (1 g/1 g infused over 3 h every 6 h intravenously) combined with imipenem-cilastatin, and the β-lactamase inhibitor xeruborbactam, is promising. Continuous infusion of full-dose cefiderocol is likely an effective treatment regimen for CR/XDR-Abc pneumonia. Zosurabalpin exhibits potent anti-CR/XDR-Abc activity in vitro, but its practical use in clinical therapy remains to be evaluated. The clinical application of antimicrobial peptides and bacteriophages requires validation.

We evaluated the safety and efficacy of different doses and treatment durations of hydroxychloroquine for COVID-19 prevention. METHOD: Databases including PubMed, Web of Science, Cochrane Library, EMBASE, Medline, and ClinicalTrials.gov were systematically searched for randomized controlled trials (RCTs) comparing different doses of hydroxychloroquine for COVID-19 prevention, from their inception to February 2024. RESULTS: A total of 20 RCTs involving 12,372 patients were included. Meta-analysis results showed no significant difference between the hydroxychloroquine and control groups in reducing the incidence of syndrome coronavirus type 2 (SARS-CoV-2) positivity (OR = 0.83, 95% CI = 0.67, 1.03). However, the subgroup receiving a daily dose of 200-400 mg (OR = 0.62, 95% CI = 0.51, 0.75) and a treatment duration of 5-8 weeks (OR = 0.52, 95% CI = 0.31, 0.88) showed statistically significant reductions in SARS-CoV-2 positivity. According to the surface under the cumulative ranking curve (SUCRA), the most effective intervention was a 200-400 mg dose for 5-8 weeks. . CONCLUSIONS: A hydroxychloroquine dose of 200-400 mg for a duration of 5-8 weeks may moderately reduce the risk of COVID-19 with a relatively low risk of adverse events.

Chronic hepatitis B (CHB) in children can progress to cirrhosis and hepatocellular carcinoma (HCC) in adulthood. Treatment options include interferons and nucleos(t)ide reverse transcriptase inhibitors (N[t]RTIs) such as tenofovir alafenamide (TAF). AREAS COVERED: This review covers the epidemiology of pediatric CHB and current treatments, with a focus on tenofovir-based therapies, particularly tenofovir disoproxil fumarate (TDF) and TAF. TDF has been used for years, but its risks of bone mineral density loss and renal impairment have raised concerns. TAF, with lower systemic exposure, appears to mitigate these risks. Ongoing trials are evaluating TAF's safety in younger children. There are knowledge gaps in long-term safety and the potential for combination therapies. EXPERT OPINION: TAF offers a safer alternative to TDF for children with CHB, showing high antiviral efficacy and fewer side effects. However, more data are needed on its use in younger children and long-term safety. The future of CHB treatment in pediatrics may include combination therapies and personalized approaches, potentially improving outcomes and minimizing risks over a lifetime of treatment. As research progresses, TAF is likely to become a cornerstone in pediatric CHB management.

RESEARCH DESIGN AND METHODS: The authors reviewed the final data using the national ethics approved CLEAR study. Thereafter, the literature is surveyed regarding the usage of ceftolozane/tazobactam to treat patients with HABP and VABP via PubMed (up to May 2024). RESULTS: Ceftolozane/tazobactam was primarily used as directed therapy to treat HABP and VABP caused by . It was primarily used alone, or in combination with another agent, to treat resistant and multidrug-resistant (MDR) P. infections. Despite primarily being used to treat severely ill patients in intensive care units, its use was associated with relatively high microbiological/clinical cure rates, along with an excellent safety profile. Several reports attest to the microbiological/clinical efficacy and safety of using ceftolozane/tazobactam to treat HABP and VABP. CONCLUSIONS: In Canada, ceftolozane/tazobactam is primarily used as directed therapy alone, or in combination, to treat MDR P. infections. Though mostly used to treat severely ill patients in the ICU, ceftolozane/tazobactam use in HABP and VABP is associated with relatively high microbiological/clinical cure rates and an excellent safety profile.

Currently available antifungal treatments, administered predominantly orally or intravenously, may not sufficiently penetrate certain body sites, and/or are associated with systemic toxicity. Little is known about how to position alternative administration approaches such as inhalational and direct drug delivery routes. AREAS COVERED: This review provides an updated overview of unconventional drug delivery strategies for managing IFD, focusing on inhalational (to target the lungs) and direct delivery methods to the central nervous system, bone/joint, and eyes. Novel compounds (e.g. opelconazole) and existing antifungals with innovative drug delivery systems currently undergoing clinical trials and/or used off-label in the clinical setting are discussed. EXPERT OPINION: For both inhalational agents and direct delivery approaches, there are similar challenges that include the absence of: approved formulations for specific administration routes, delivery vehicles that are simple and safe to use whilst maintaining potency and efficiency of delivery, animal models suitable for investigating pharmacokinetic/pharmacodynamic profiles of inhaled antifungals, and consensus on the composite endpoints and intervals for of follow-up in clinical trials. To meet these challenges, cooperation of all stakeholders in drug development and regulation is required.

In this regard, nanotechnology can be an alternative for the treatment of infectious microbes. Curcumin has been used since ancient times as antimicrobials; however, it has limitations due to its less aqueous solubility, bioavailability, and biocompatibility. This problem can be solved by curcumin-derived carbon nanodots, which are emerging antimicrobials of <10 nm size, water-soluble, biocompatible, less toxic, and fluorescent. AREAS COVERED: The review discusses the application of curcumin-derived carbon nanodots against various pathogenic microbes including bacteria and dreaded viruses like SARS-CoV-2. In addition, the role of curcumin carbon nanodots in biolabelling of pathogenic microbes, mechanism of action, bioimaging, and therapy has been critically examined. EXPERT OPINION: Carbon nanodots play an important role in combating pathogenic microbes by early diagnosis, bioimaging, nanocarrier for antimicrobial drugs, and therapy of infectious diseases. Curcumin carbon nanodots have already demonstrated their benefits of being water soluble, bioavailable, and biocompatible. However, more thorough research is needed to understand the efficacy and safety of curcumin carbon nanodots. In the future, curcumin-derived carbon nanodots can be used as alternative antimicrobial agents to fight microbial infections including multidrug-resistant microbes.

These lesions, traditionally considered inert and asymptomatic, have been associated with several complications that seem to be mostly related to brain damage and inflammation ensuing as the result of the exposure of the host's immune system to parasitic antigens trapped within calcifications. AREAS COVERED: This review, based on the search of different electronic databases up to May 2024, focuses on the reported correlates and complications of calcified cysticerci (chronic headaches, seizures/epilepsy, hippocampal atrophy/sclerosis, gliomas), and the different interventions developed for their prevention and treatment. Common analgesics, non-steroidal anti-inflammatory drugs, corticosteroids, and antiseizure medications have been used with success but, with the exception of the latter, these drugs offer temporary relief of symptoms and support for their use is based on level 3 evidence. EXPERT OPINION: Several strategies may reduce the severity of clinical consequences of calcified cysticerci. Probably, the most relevant intervention would be the prevention of their occurrence or reduction in their size. In this view, the use of bisphosphonates appears as a potential option that needs to be tested in humans.

These infections result in high mortality and morbidity rates along with delays in chemotherapy, longer hospitalizations, and increased health care costs. AREAS COVERED: Treatment alternatives for CRO infections in PHMs. EXPERT OPINION: The best available treatment option for KPC and OXA-48 producers is ceftazidime/avibactam. Imipenem/cilastatin/relebactam and meropenem/vaborbactam remain as the alternative options. They can also be used as salvage therapy in KPC-positive infections resistant to ceftazidime/avibactam, if susceptibility is shown. Treatment of metallo-β-lactamase producers is an unmet need. Ceftazidime/avibactam plus aztreonam or aztreonam/avibactam seems to be the most reliable option for metallo-β-lactamase producers. As a first-line option for carbapenem-resistant infections, ceftolozane/tazobactam is preferable and ceftazidime/avibactam and imipenem/cilastatin/relebactam constitute alternative regimens. Although sulbactam/durlobactam is the most reliable option against carbapenem-resistant infections, its utility as monotherapy and in PHMs is not yet known. Cefiderocol can be selected as a 'last-resort' option for CRO infections. New risk score models supported by artificial intelligence algorithms can be used to predict the exact risk of infections in previously colonized patients.

Rapid changes such as fluid shifts, hyperdynamic states, and altered renal clearance often require special attention for better clinical outcomes. Vital organ dysfunction, with or without MODS, often necessitates supportive management like RRT, ventilatory support, and ECMO. These interventions can significantly affect the PK/PD of administered antimicrobials, complicating effective treatment. AREA COVERED: Patient-specific parameters such as age, weight, and comorbid illnesses (e.g. cystic fibrosis, burns, and immunocompromised states) are critical determinants of antimicrobial pharmacokinetics. Understanding PK/PD determinants is crucial for developing optimized dosing regimens that enhance therapeutic efficacy and minimize toxicity in critically ill patients. EXPERT OPINION: Incorporating pharmacometrics approaches in dose optimization can significantly improve patient outcomes. This review focuses on the nuances of PK/PD for optimized antimicrobial dosing in critically ill septic patients, emphasizing the importance of individualized treatment plans to address the complex and dynamic needs of this patient population. The adoption of these advanced pharmacokinetic and pharmacodynamic principles into clinical practice is essential for advancing patient care and optimizing therapeutic outcomes in critically ill patients.

Although it was eventually superseded by azole antifungals due to its long treatment duration and reliance on keratopoiesis, griseofulvin remains notable for its effectiveness and safety in treating tinea capitis, especially when caused by . However, due to a decline in cases and commercial unavailability, alternative treatments are now required. AREAS COVERED: The following topics regarding to other treatments were discussed: (I) The efficacy of alternative antifungal agents such as terbinafine, itraconazole, and fluconazole, in the treatment of tinea capitis. (II) The use and role of topical therapies. (III) Experience in the management of tinea capitis. EXPERT OPINION: The usefulness of oral terbinafine as a replacement for griseofulvin in the treatment of tinea capitis and why it is the preferred drug in elderly patients was discussed. Challenges with spp. and the use of fluconazole in pediatric patients were also analyzed. Support for the use of topical treatment as an adjunctive treatment for tinea capitis was highlighted.

AREAS COVERED: This review focuses on agents that have completed or ongoing phase-3 studies. A PubMed search was conducted up to 31 May 2024. EXPERT OPINION: Novel agents in late-stage clinical development belong to the β-lactam or β-lactam/β-lactamase inhibitor combinations class and display variable antimicrobial activity depending on the specific β-lactamases expressed by GNB, particularly carbapenemases. While many of these novel agents demonstrate in vitro activity against carbapenem-resistant GNB, their efficacy has mainly been evaluated in phase-3 randomized controlled trials (RCT) for infections caused by carbapenem-susceptible GNB. Although evidence from real-world observational studies is generally less robust than that from RCT, it could be crucial for updating clinical guidelines on treating carbapenem-resistant GNB with these new agents in the absence of dedicated RCT.

This study sought to investigate ERV's effectiveness and safety in treating Gram-negative pathogens (GNPs) infections. METHODS: We conducted a comprehensive search of PubMed, Cochrane Library, Embase, Web of Science, and ClinicalTrials.gov up to September 2023. Included in the review were studies assessing the efficacy or safety of ERV in treating GNP infections. RESULTS: Three randomized controlled trials, seven cohort studies, and two case reports were included. There was no statistically significant difference between ERV and comparators in clinical cure (OR = 0.84, 95% CI = 0.59-1.19), microbiologic eradication (OR = 0.69, 95% CI = 0.36-1.33), and mortality (OR = 1.66, 95% CI = 0.81-3.41). However, a significantly higher rate of adverse events with ERV was observed compared to the control group (OR = 1.55, 95% CI = 1.21-1.99). Additionally, cohort studies reported a clinical cure rate of 73.2% (88.8% in RCTs), an AE rate of 4.5% (38.3% in RCTs), and mortality of 16.2% (1.5% in RCTs). Patients in RCTs received ERV monotherapy, whereas almost half of the patients in cohort studies were treated with ERV in combination with other antibiotics. CONCLUSIONS: Further studies are warranted to investigate the safety and efficacy of ERV monotherapy or combination therapy in critically ill patients.

Literature in this space that has utilized varying diagnostic criteria and ideal outcome measures for success is unclear. AREAS COVERED: This scoping review assesses methods of diagnosis of DFO and definitions of treatment outcomes in the literature assessing antibiotic therapy for treatment of DFO. EXPERT OPINION: There is a lack of consensus in the design of diabetic foot trials, resulting in difficulty for clinicians to assess and manage serious conditions such as DFO. The cure for DFO is challenging to ascertain and treatment failure may be a better approach to assess outcomes in research assessing the efficacy of antibiotic therapy. In the absence of gold-standard diagnostic tools, practical approaches to outcome assessment may allow for greater clinical applicability of available data.
