Bactogram: Spatial Analysis of Bacterial Colonisation in Epidermal Wounds.

Skin barrier damage and subsequent development of harmful microbiota contribute to conditions such as wound infections, atopic dermatitis and chronic wounds, which impact millions of people globally and pose a significant economic burden on healthcare systems. Established microbial sampling methods, such as swabs and tissue biopsies, provide limited information on the spatial distribution of bacteria. We here describe a new method that produces a visual map of the distribution of cultivable bacteria, denoted 'Bactogram', across the whole wound and surrounding skin, suitable for image-based quantification.

Chemotherapy-Induced Cutaneous Sclerosis: A Rare Clinical Finding.

Scleroderma-like cutaneous sclerosis has been reported as a rare adverse reaction to several drugs, including the chemotherapeutical agent paclitaxel, used in therapeutic regimens for several malignancies. The sclerosis is usually limited to the skin, most commonly presenting in the lower limbs after weeks to months of therapy but is often refractory to treatment and progresses even after discontinuation of the offending agents, with significant resulting morbidity. We report a rare case of severe cutaneous sclerosis secondary to chemotherapy with nab-paclitaxel and gemcitabine, which did not respond to treatment and led to discontinuation of chemotherapy.

Bottom-Up Formation of III-Nitride Nanowires: Past, Present, and Future for Photonic Devices.

The realization of semiconductor heterostructures marks a significant advancement beyond silicon technology, driving progress in high-performance optoelectronics and photonics, including high-brightness light emitters, optical communication, and quantum technologies. In less than a decade since 1997, nanowires research has expanded into new application-driven areas, highlighting a significant shift toward more challenging and exploratory research avenues. It is therefore essential to reflect on the past motivations for nanowires development, and explore the new opportunities it can enable.

Vasorelaxant effect of phenylpropanoids: Methyl eugenol and eugenol in human umbilical cord vein.

Methyl-eugenol (ME) and eugenol (EUG) are phenylpropanoids with vasodilatory effects. While EUG's vasorelaxant effect in human umbilical artery (HUA) is known, their action in veins is unclear. This study aimed to evaluate ME and EUG in human umbilical vein (HUV).

The Influence of Genetic Polymorphisms on the Expression of Interleukin-1beta, Prostaglandin E2 and Tumor Necrosis Factor Alpha in Peri-Implant Crevicular Fluid: A Cross-Sectional Study.

The aim of this study was to evaluate the possible relationships between polymorphisms in the interleukin-1 () , , and genes and concentrations of the inflammatory mediators IL-1β, tumor necrosis factor-alpha (TNF-α), and prostaglandin E2 (PGE2) in peri-implant crevicular fluid (PICF). A cross-sectional analytical study was conducted on 51 patients with dental implants. Samples from the buccal mucosa were obtained, and genetic analysis was performed using the real-time polymerase chain reaction (PCR) technique for and and PCR and restriction fragment length polymorphism analysis for .

Mycosis Fungoides and Granulomatous Slack Skin: A Single Entity With Distinct Clinical Phenotypes.

Granulomatous cutaneous T-cell lymphoma includes mycosis fungoides with significant granulomatous inflammation (GMF) and granulomatous slack skin (GSS), listed in the WHO classification as a subtype of mycosis fungoides (MFs). 1 These overlapping entities have shared clinical and histopathologic features which can present a diagnostic challenge. The dominance of the granulomatous infiltrate and the often sparse lymphocytic infiltrate frequently with minimal cytological atypia are features that distract from the correct diagnosis, even when raised by the clinician.

Differential diagnosis between urticarial vasculitis and chronic spontaneous urticaria: An international Delphi survey.

Background: Urticarial vasculitis (UV) should be differentiated from chronic spontaneous urticaria (CSU) in patients initially presenting with recurrent wheals, although criteria for differential diagnosis remain ill-defined.

Objectives: To set the goals, define criteria and unmet needs in UV diagnosis and differential diagnosis with CSU, and explore the possibility of coexistence of both diseases.

Methods: Thirteen experts experienced in UV research participated in a Delphi survey of European Academy of Allergy and Clinical Immunology taskforce.

Socioeconomic Inequalities and Predictors of Cardiac Rehabilitation Referral: Real-World Evidence.

Objective: The aim of the study is to identify factors associated with cardiac rehabilitation referral after an acute coronary syndrome at a university hospital.

Design: We analyzed 2814 hospitalizations due to acute coronary syndrome between 2017 and 2019 in Centro Hospitalar São João. The hospital's morbidity database was used to retrieve patient information.
