Abstract
Neonatal sepsis is a major cause of morbidity and mortality in neonates. A particular concern is the increasing prevalence of antibiotic-resistant strains among neonatal intensive care units (NICUs). Two novel beta-lactam/beta-lactamase inhibitors have recently been approved for use in neonates with multidrug-resistant infections: [...] Read more.
Neonatal sepsis is a major cause of morbidity and mortality in neonates. A particular concern is the increasing prevalence of antibiotic-resistant strains among neonatal intensive care units (NICUs). Two novel beta-lactam/beta-lactamase inhibitors have recently been approved for use in neonates with multidrug-resistant infections: ceftazidime/avibactam and ceftolozane/tazobactam. These agents demonstrate efficacy against a range of multidrug-resistant gram-negative pathogens, including extended-spectrum beta-lactamases (ESBL)-producing and carbapenem-resistant Enterobacterales, as well as multidrug-resistant Pseudomonas aeruginosa. This narrative review aims to summarize the current knowledge concerning the utilization of ceftazidime/avibactam and ceftolozane/tazobactam in the NICU. According to the existing literature, both agents have been shown to be highly effective with a favorable safety profile in the neonatal population. Full article

Background/Objectives: Diabetes mellitus is a group of chronic metabolic disorders characterized by persistent hyperglycemia. Aldose reductase, the first enzyme in the polyol pathway, plays a key role in the onset of long-term diabetic complications. Aldose reductase inhibition has been widely established as a potential pharmacotherapeutic approach to prevent and treat diabetes mellitus-related comorbidities. Although several promising aldose reductase inhibitors have been developed over the past few decades, they have failed in clinical trials due to unacceptable pharmacokinetic properties and severe side effects. This paper describes the design, synthesis, and pharmacological evaluation of four novel 5-halogenated N-indolylsulfonyl-2-fluorophenol derivatives (3a-d) as aldose reductase inhibitors. Methods: The design of compounds was based on a previously published lead compound (IIc) developed by our research group to enhance its inhibitory capacity. Compounds 3a-d were screened for their ability to inhibit in vitro partially purified aldose reductase from rat lenses, and their binding modes were investigated through molecular docking. Results: The presence of a sulfonyl linker between indole and o-fluorophenol aromatic rings is mandatory for potent aldose reductase inhibition. The 5-substitution of the indole core with halogens resulted in a slight decrease in the inhibitory power of 3a-c compared to IIc. Among halogens, bromine was the most capable of filling the selectivity pocket through hydrophobic interactions with Thr113 and Phe115 residues. Conclusions: Although our strategy to optimize the inhibitory potency of IIc via inserting halogen atoms in the indole scaffold was not fruitful, aromatic ring halogenation can be still utilized as a promising approach for designing more potent aldose reductase inhibitors.

Background/Objectives: Oppositional defiant disorder (ODD) and conduct disorder (CD) are important behavior disorders in children and adolescents, often linked with long-term psychosocial problems. Antipsychotics are frequently prescribed to manage severe symptoms and improve behavior, but their efficacy in this population is still unclear and a lot of physicians are remittent in prescribing them. This systematic review aims to assess the effectiveness of antipsychotic treatment in reducing symptoms associated with ODD and CD in children and adolescents. Methods: Studies that investigated how effective antipsychotic treatments are for children and teens diagnosed with oppositional defiant disorder (ODD) and conduct disorder (CD) were reviewed. Only studies that met a few main criteria were included: participants were between 5 and 18 years old with an ODD or CD diagnosis; the treatment could be any type of antipsychotic, whether typical or atypical; the accepted study designs were randomized controlled trials (RCTs), cohort studies, systematic reviews with meta-analysis, or observational studies. The outcomes of interest were reductions in aggressive or defiant behaviors, improvements in social functioning, and the occurrence of any adverse effects from the medications. There was no restriction on the language of publication, and studies published from 2000 to 2024 were considered. Studies that focused only on non-antipsychotic drugs or behavioral therapies, as well as case reports, expert opinions, and non-peer-reviewed articles did not meet the inclusion criteria. Results: The review consisted of 13 studies. The results suggest that some antipsychotic drugs—especially atypical antipsychotics—can substantially reduce aggressive and defiant behavior in children and adolescents who have oppositional defiant disorder (ODD) or conduct disorder (CD). Common side effects of these medications include weight gain, sedation, and metabolic problems. Conclusions: Although adverse effects are a concern, the potential of these medications to manage disruptive behaviors should not be overlooked. When used in combination with behavioral therapy and other forms of treatment, antipsychotics can markedly improve the outcomes of these very difficult-to-treat patients. Clinicians who treat these patients need to consider antipsychotics as a serious option. If they do not, they are denying their patients medication that could greatly benefit them. Full article
