BACKGROUND: Endometritis is a postpartum complication that is more common after cesarean delivery. It frequently requires intravenous antibiotic administration, prolonged hospital stays, and carries a risk of sepsis or abscess formation. Precesarean vaginal preparation has been shown to decrease the risk of endometritis in patients who have labored or have ruptured membranes. OBJECTIVE: The objective of this study was to assess the practical implementation of a protocol for vaginal cleansing prior to cesarean delivery and the subsequent effect on endometritis rates in a clinical setting...

Marion Dubald, Sandrine Bourgeois, Véronique Andrieu, Hatem Fessi
The last fifty years, ophthalmic drug delivery research has made much progress, challenging scientists about the advantages and limitations of this drug delivery approach. Topical eye drops are the most commonly used formulation in ocular drug delivery. Despite the good tolerance for patients, this topical administration is only focus on the anterior ocular diseases and had a high precorneal loss of drugs due to the tears production and ocular barriers. Antibiotics are popularly used in solution or in ointment for the ophthalmic route...

BACKGROUND: Periodontitis is a chronic inflammatory disease, which affects the supporting tissues of the teeth, and without proper treatment it may lead to tooth loss. Antibiotics - dministered orally - have been widely used in the treatment of periodontitis. With the conventional administration routes, adequate drug levels cannot be reached in the periodontal pockets and oral application of antimicrobials could lead to side effects. Drug delivery systems containing antibiotics, administered at the site of infection, could possibly help eliminate pathogen bacteria and treat periodontitis...

Cell-penetrating peptides (CPPs) and antimicrobial peptides (AMPs) share certain physicochemical parameters such as amphipathicity, hydrophobicity, cationicity and pI, due to which these two groups of peptides also exhibit overlapping functional characteristics. In our current work, we have evaluated antimicrobial properties of cell-penetrating peptides derived from Latarcin1. Latarcin derived peptide (LDP) exhibited antimicrobial activity against representative microorganisms tested and bactericidal effect against methicillin resistant Staphylococcus aureus (MRSA), which was used as model organism of study in the present work...

As an antibiotic that prevents and treats infections caused by Gram-positive bacteria such as Staphylococcus aureus, vancomycin incorporated in a biodegradable polymer poly(lactide-co-glycolide) provides opportunities to construct controlled-release drug delivery systems. Developments associated with this promising system have been largely concentrated on areas of drug delivery kinetics and biodegradability. In order to provide surface analytical approaches to this important system, the authors demonstrate applicability of time-of-flight secondary ion mass spectrometry (TOF-SIMS) in three-dimensional molecular imaging for a model system consisting of alternating layers of ploy(lactide-co-glycolide) and vancomycin...

The emergence of multidrug-resistant bacterial pathogens has led to a global public health emergency and novel therapeutic options and drug-delivery systems are urgently needed. Cefiderocol is a siderophore cephalosporin antibiotic that has recently been developed to combat a variety of bacterial pathogens, including β-lactam- and carbapenem-resistant organisms. Areas covered: This paper provides an overview of the mutational and plasmid-mediated mechanisms of β-lactam and carbapenem resistance, the biochemical pathways of siderophores in bacterial iron metabolism, and how cefiderocol may be able to provide better targeted antimicrobial therapy that escape these drug-resistant mechanisms...

The acidic environment at bacterial infection sites is a potential external stimulus for targeted antibiotic delivery. This paper reports new biocompatible pH-sensitive lipids (PSLs) with three hydrocarbon tails, and a head group with a secondary amine and carboxylate function for site-specific nano delivery of vancomycin (VCM). PSLs formed stable liposomes with mean vesicle diameters and polydispersity indices between 99.38 ± 6.59 nm to 105.60 ± 5.38 nm and 0.161 ± 0.003 to 0.219 ± 0...

BACKGROUND: An estimated 282 women die for every 100,000 live births in Myanmar, most due to preventable causes. Auxiliary Midwives (AMWs) in Myanmar are responsible for providing a package of care during pregnancy and childbirth to women in rural hard to reach areas where skilled birth attendants (Midwives) are not accessible. This study aims to examine the role of AMWs in Myanmar and to assess the current practices of three proposed essential maternal interventions (oral supplement distribution to pregnant women; administration of misoprostol to prevent postpartum haemorrhage; management of puerperal sepsis with oral antibiotics) in order to facilitate a formal integration of these tasks to AMWs in Myanmar...

BACKGROUND: Periodontitis is a bacterially-induced, chronic inflammatory disease that destroys the connective tissues and bone that support teeth. Active periodontal treatment aims to reduce the inflammatory response, primarily through eradication of bacterial deposits. Following completion of treatment and arrest of inflammation, supportive periodontal therapy (SPT) is employed to reduce the probability of re-infection and progression of the disease; to maintain teeth without pain, excessive mobility or persistent infection in the long term, and to prevent related oral diseases...

Aztreonam, a broad-spectrum monobactam, is typically reserved for multidrug resistant (MDR) infections. Pharmacokinetic (PK) data to guide dosing in children, however, are limited to healthy volunteers or nonintensive care unit (ICU) patients. Impaired antibiotic delivery into tissue remains a major concern and may explain the high morbidity and mortality associated with MDR infections. Therefore, evaluating the PK changes in pediatric ICU patients is necessary to elucidate the most appropriate antimicrobial regimen...

Penetration of antibiotics into and through the cornea is a major limiting factor in the treatment of ocular infections. Several strategies are in vogue to overcome this limitation such as use of fortified drops, gels, and subconjunctival injections. Here, we present the fabrication of rapidly dissolving polymeric microneedle array to effectively deliver besifloxacin through the cornea. Microneedles were prepared using polyvinyl alcohol and polyvinyl pyrrolidone by the micromolding technique. The model fluoroquinolone antibiotic, besifloxacin, was loaded in 36 microneedles arranged in a 6 × 6 array format within a 1 cm2 area...

Microbial biofilms, which are elaborate and highly resistant microbial aggregates formed on surfaces or medical devices, cause two-thirds of infections and constitute a serious threat to public health. Immunocompromised patients, individuals who require implanted devices, artificial limbs, organ transplants, or external life support and those with major injuries or burns, are particularly prone to become infected. Antibiotics, the mainstay treatments of bacterial infections, have often proven ineffective in the fight against microbes when growing as biofilms, and to date, no antibiotic has been developed for use against biofilm infections...

The efficacy of rifapentine, an oral antibiotic used to treat tuberculosis, may be reduced due to degradation at gastric pH and low solubility at intestinal pH. We hypothesized that delivery properties would be improved in vitro by incorporating rifapentine into pH-responsive amorphous solid dispersions (ASDs) with cellulose derivatives including: hydroxypropylmethylcellulose acetate succinate (HPMCAS), cellulose acetate suberate (CASub), and 5-carboxypentyl hydroxypropyl cellulose (CHC). ASDs generally reduced rifapentine release at gastric pH, with CASub affording >31-fold decrease in area under the curve (AUC) compared to rifapentine alone...
