The current pandemic of Coronavirus Disease 2019 (COVID-19) raised several concerns about using conventional textiles for manufacturing personal protective equipment without self-disinfecting properties since the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is transmitted mainly by aerosols that can transpose cotton masks. Therefore, developing new cotton fibers with high self-disinfecting ability is essential to avoid a new pandemic due to new SARS-CoV-2 variants. Herein, we developed cotton wipes (CFs) with fibers coated by Ag, TiO, and Ag/TiO hybrid nanoparticles like Brazilian heavy-fruited by a sonochemical approach. Moreover, the coated CFs present high antimicrobial performance against () and (), being able to inactivate infectious SARS-CoV-2 (Delta variant) by the destruction of the spike, membrane, and nucleocapsid proteins while the viral RNA is not significantly affected, according to the molecular biological findings.

Cloth versus disposable diapers: an exploratory study on family habits.
J Pediatr (Rio J)
December 2024
Universidade Federal do Paraná (UFPR), Departamento de Pediatria, Divisão de Dermatologia Pediátrica, Curitiba, Brazil.
Objective: To describe features and habits of diaper area care and compare the frequency of diaper dermatitis in infants using cloth diapers with those using disposable diapers.
Methods: Questionnaires were administered to families with infants who had not started potty training, to assess the frequency of diaper rash in two groups: babies who use exclusively cloth diapers (CD), and others with exclusively disposable diapers (DD). The hygiene methods of the perineal region and the skin lesions frequency were evaluated.
Microencapsulation of oil and extracts blend for single-use applications.

Article Synopsis
- This study explores a new method for creating antiseptic wipes by using microencapsulation to combine antimicrobial properties of A.I. oil and T.C. extracts.
- Microcapsules were made with a 1:1 ratio of A.I. and T.C., using sodium alginate, and were evenly distributed in non-woven cotton fabric.
- The treated fabric significantly reduced bacteria, showing effectiveness against both Gram-positive (up to 99%) and Gram-negative (up to 99%) strains, while only slightly decreasing in whiteness, indicating potential for infection control applications.

High-performance flexible semiconductor material can be used as an excellent multifunctional matrix for in-situ ultrasensitive surface-enhanced Raman scattering (SERS) detection and synchronous photocatalytic degradation of antibiotic residues in aquatic ecosystem. Here, a calcium-doped TiO flexible matrix with double defects (surface oxygen vacancy defect and Ti energy level defect) was developed by its "in-situ one-step" hydrothermal synthesis on cotton fabric for the above purposes. Due to the joint contribution of double defects, a multi-channel charge transfer mode and a high-efficiency carrier separation are achieved, which endows flexible cotton fabric/Ca-doped TiO (Cot/Ca-TiO) substrate with the greatly boosted SERS effect for in-situ detection of antibiotic residues on fish body surface and in fishpond water by a simple wiping or dipping sampling method, even for simultaneous identification of multi-component residues.

Department of Periodontics, Preventive and Restorative Dentistry, University Medical Center Hamburg-Eppendorf, Hamburg 20246, Germany.
Article Synopsis
- Periodontitis is commonly diagnosed in patients with ascitic decompensated liver cirrhosis, found in 82% of the study group compared to 59% in a control group, suggesting a strong correlation between the two conditions.
- The study utilized PCR testing on gingival samples, ascites, and stool but found no evidence of specific periodontitis pathogens in ascites, although some were present in stools and gums.
- Patients with periodontitis showed a significantly higher survival rate and transplant-free survival compared to those without, indicating a potential protective effect of periodontitis in this cohort.
