Summary: The spread of biofilms on medical implants is a major contributor to persistent and chronic infections in clinical settings. This article reviews recent studies on biofilm formation and microbial colonization on a wide range of indwelling devices. The focus is on bacterial abundance and distribution across different devices and body sites, as well as the role of environmental features and the interaction between bacterial colonization and the human immune system.

Summary: This study reports a one-step, clean and effective surface engineering approach called laser surface treatment (LST) to tackle the challenge of device associated infection (DAI) in total joint replacement (TJR). The results showed that LST significantly reduces biofilm coverage of multiple bacterial species on CP Ti surfaces. Moreover, the laser-treated CP Ti was found to be non-toxic to cells. The reduction in biofilm coverage can be attributed to the changes in surface roughness, topography, and oxide concentration after LST.

Summary: The authors reviewed 31 studies and concluded that no different surgical approaches should be adopted for revision surgery following implant-based breast surgery in patients with textured devices, as long as a correct approach is performed to face complications or adverse events, following a thorough preoperative study of the patient with the proper diagnostic tools.

Summary: This study evaluated the introduction of nanotextured implants alongside conventional textured implants and compared early complications. Results showed that nanotextured implants were associated with higher complication rates in the early period, but improvements were seen over time with modifications in patient selection, intraoperative techniques, and postoperative care.

Summary: This study investigates the local peri-implant pH changes caused by sterile inflammation and bacterial and fungal infections. A sensing electrode based on polyaniline and poly(2-methyl-2-oxazoline) on a titanium alloy support is developed for early detection of these pathologies. The results show statistically significant pH changes caused by different bacteria and yeast, with potential for identifying the nature of the infection. The developed electrodes have a wide pH response range and can contribute to the next generation of biosensors.

Summary: This study developed a bench model for capsular contracture and measured the surface area of implants to evaluate the degree of contracture. The results showed that the decrease in surface area was correlated with the degree of contracture, and anatomically shaped implants had consistent surface area changes at different heights.

Summary: The injection of Clostridium histolyticum collagenase (CCH) has been shown to be a safe and effective approach in degrading capsule tissue induced by fractionated irradiation in an animal model. It significantly reduces capsule thickness and collagen density, potentially paving the way for clinical application in implant-based breast reconstruction patients.

Summary: This study reviewed otology-related studies using the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database to identify the opportunities and limitations of using MAUDE. Eight studies met the inclusion criteria, but all were of poor quality. The main reasons for the poor quality were MAUDE's structural limitations as a passive surveillance system using nonstandardized free-text reports. The quality of studies could be improved by implementing case report best practices and standardizing adverse event reporting in MAUDE.

Summary: Based on available literature, aspiration technique does not offer a reliable safety measure for filler injections, and it is safer to utilize injection techniques that avoid vascular injection rather than relying on aspiration.

Summary: This study visualized and measured the movement of the needle tip during aspiration and injection of hyaluronic acid filler in real time. It found that aspiration causes retrograde movement of the needle tip, while injection causes anterograde movement. Double-handed aspiration and greater experience reduce needle tip movement. The study suggests that it is not advisable to rely solely on aspiration to prevent intravascular injection.

Summary: This study evaluated women with breast implants attending a breast implant assessment clinic and captured clinical and implant data. The results showed that breast implants have certain complications, but having properly trained and certified practitioners perform the surgery can lower the risk.

Summary: This study evaluated the safety and efficacy of targeted verifiable subcision (TVS) for the treatment of cellulite on the buttocks and thighs. The results showed that a single TVS treatment has durable efficacy and safety in reducing cellulite for up to 12 months.

Summary: Staphylococcus aureus biofilms exhibit resistance to antibiotics and disinfectants, which is attributed to changes in the bacterial cell wall. Proteins involved in cell wall synthesis are upregulated in biofilms compared to planktonic organisms. Furthermore, the width of the cell wall and peptidoglycan production increase with biofilm culture duration and dehydration. Disinfectant tolerance is highest in dry surface biofilms, followed by hydrated biofilms, and lowest in planktonic bacteria, indicating that changes in the cell wall may contribute to the biocide resistance of S. aureus biofilms.

Summary: This study established a consensus panel to investigate the pathogenesis of delayed-onset tissue nodules (DTNs) due to hyaluronic acid (HA) injections. Consensus was reached on 16 out of 20 questions, forming the basis for a classification and treatment guide. The study suggests that DTNs are likely infection initiated with a variable immune response, and attention to practitioner and patient hygiene, as well as early systemic infection treatment, is important.

Summary: A rare complication of breast implants is the development of lymphoma, which usually requires time-consuming and costly laboratory testing for diagnosis. This research presents a method for quickly detecting lymphoma using a smaller amount of fluid, potentially enabling point-of-care diagnosis in the future.
