Dalbavancin is a relatively new long-acting anti-Gram positive antimicrobial approved for the treatment of acute bacterial skin and skin structures infections. An increasing number of observational studies and case series were published on its off-label uses. Great interest is emerging about complicated cases where antibiotic treatment cannot be discontinued, and a chronic suppressive therapy is needed. We described a case series of 6 patients treated or ongoing on treatment with dalbavancin as chronic suppressive therapy (CAST) administered with the following regimen: dalbavancin 1500 mg on day 1 and 8 and then every 4 weeks...

INTRODUCTION: Diabetic foot infection (DFI) is one of the complications of diabetes mellitus. Clindamycin (CLY) is one of the antibiotics recommended to treat DFI, but CLY given orally and intravenously still causes many side effects. METHODS: In this study, we encapsulated CLY in a bacteria sensitive microparticle system (MP-CLY) using polycaprolactone (PCL) polymer. MP-CLY was then delivered in a separable effervescent microarray patch (MP-CLY-SEMAP), which has the ability to separate between the needle layer and separable layer due to the formation of air bubbles when interacting with interstitial fluid in the skin...

This case report aims to delineate the challenges and management strategies for a patient with bilateral mutilated hands within a secondary care level in Mexico, contributing to medical literature and potentially guiding future patient care. Mutilated hands represent a significant surgical and rehabilitative challenge due to the profound structural damage they cause, leading to considerable functional impairment and psychological distress. The complexity of these injuries necessitates a multidisciplinary approach, particularly in resource-constrained settings...

Recently, they have been used for outpatient antimicrobial therapy for complicated infections. No head-to-head studies exist for this purpose. OBJECTIVE: To compare outcomes of patients treated with multiple doses of oritavancin or dalbavancin for complicated infections. PATIENTS AND METHODS: This was a single-center, retrospective cohort study evaluating adult patients who received 2 or more doses of lipoglycopeptides for complicated infections from February 2019 through December 2022...

Skin is constantly exposed to injury and infectious agents that can compromise its structural integrity and cause wounds. When this occurs, microorganisms from the skin microbiota and external bacteria and fungi can penetrate the wound and cause an infection, which complicates the healing process. Nowadays, there are several types of wound dressings available to treat wounds, some of which are incorporated with antimicrobial agents. However, the number of microorganisms resistant to these substances is rising...

Group A Streptococcus (Strep A) bacteria causes a broad spectrum of diseases. The most common manifestations of Strep A infection are sore throat and pus-producing skin infections such as impetigo. Complications of Strep A infection can lead to inflammation in the bones, muscles, joints, and internal organs causing acute rheumatic fever and rheumatic heart disease (RHD). In The Gambia, the RHD burden is thought to be very high. However, epidemiological data is minimal, and Strep A control programmes do not exist...

INTRODUCTION: Extensively drug-resistant Pseudomonas aeruginosa (XDR-PA) is a growing concern due to its increasing incidence, limited therapeutic options, limited data on the optimal treatment, and high mortality rates. The study aimed to characterize the population, the outcome and the microbiological characteristics of XDR-PA identified in a Portuguese university hospital center. METHODS: All XDR-PA isolates between January 2019 and December 2021 were identified...

Atopic dermatitis (AD), a prevalent skin condition often complicated by microbial infection, poses a significant challenge in identifying the responsible pathogen for its effective management. However, a reliable, safe tool for pinpointing the source of these infections remains elusive. In this study, we propose a novel on-site pathogen detection that combines chemically functionalized nanotopology with genetic analysis to capture and analyze pathogens closely associated with severe atopic dermatitis. The chemically functionalized nanotopology features a 3D hierarchical nanopillar array (HNA) with a functional polymer coating, tailored to isolate target pathogens from infected skin...

Tracheostomy is a very common airway procedure in the treatment of critically ill neurological patients. At present, the traditional tracheal cannula fixation belt is easy to be contaminated, difficult to disinfect, and needs to be replaced regularly. It is prone to infection, skin injury, unplanned extubation and other adverse events, which cannot meet the clinical treatment effect and patient safety management. In order to overcome the above problems, the medical staff of the neurology intensive care unit of Henan Provincial People's Hospital designed a new type of tracheal cannula fixation belt to increase patient comfort and reduce complications, and obtained a National Utility Model Patent of China (ZL 2022 2 0855188...

Diabetic wounds are a significant subset of chronic wounds characterized by elevated levels of inflammatory cytokines, matrix metalloproteinases (MMPs), and reactive oxygen species (ROS). They are also associated with impaired angiogenesis, persistent infection, and a high likelihood of hospitalization, leading to a substantial economic burden for patients. In severe cases, amputation or even mortality may occur. Diabetic foot ulcers (DFUs) are a common complication of diabetes, with up to 25% of diabetic patients being at risk of developing foot ulcers over their lifetime, and more than 70% ultimately requiring amputation...

AIMS: Autonomic dysfunction with central autonomic network (CAN) damage occurs frequently after intracerebral hemorrhage (ICH) and contributes to a series of adverse outcomes. This review aims to provide insight and convenience for future clinical practice and research on autonomic dysfunction in ICH patients. DISCUSSION: We summarize the autonomic dysfunction in ICH from the aspects of potential mechanisms, clinical significance, assessment, and treatment strategies...

Burns are the fourth most common type of injury worldwide. Many patients also suffer numerous infections and complications that impair the burn healing process, which makes the treatment of burns a challenge. This study aimed to prepare and characterize nano-emulsion (NE) of propolis, hyaluronic acid, and vitamin K for treatment of second-degree burns. High-Pressure Liquid Chromatography (HPLC) was used for the qualitative assessment of the phenolic and flavonoid contents in crude propolis. The structural, optical, and morphological characterization, besides the antimicrobial, antioxidant, cytotoxicity, in-vitro, and in-vivo wound healing activities were evaluated...

An increasing amount of evidence has linked critical illness with dysbiotic microbiome signatures in different body sites. The disturbance of the indigenous microbiota structures has been further associated with disease severity and outcome and has been suggested to pose an additional risk for complications in intensive care units (ICUs), including hospital-acquired infections. A better understanding of the microbial dysbiosis in critical illness might thus help to develop strategies for the prevention of such complications...

Background: Due to the heterogeneity of critically ill patients, the pharmacokinetics of tigecycline are unclear, and the optimal dosing strategy is controversial. Methods: A single-center prospective clinical study that included critically ill patients who received tigecycline was performed. Blood samples were intensively sampled (eight samples each), and plasma drug concentrations were determined. A population pharmacokinetic (PPK) model was developed and evaluated by goodness-of-fit plots, bootstrap analysis and visual predictive checks...
