The development of biofilms is an interesting strategy to reduce the use of conventional packaging materials to preserve and prolong the shelf life of foods. In this study, different concentrations of sodium alginate (SA) (0, 0.5, 1.0, 1.5 and 2.0% w/v) and glycerol (GL) (6.0, 4.0, 2.0, 1.0 and 0% w/v) on the properties of enriched films with orange peel (OP) powder were investigated. Physical, structural, thermal, mechanical, and barrier properties were characterized. The results revealed that incorporation of glycerol to OP-SA film-making solution trend to flexible and opaque films, while unplasticized sample did not form flexible films and were glossy. Moreover, decreasing glycerol and simultaneously increase alginate content led to decrease film thickness, moisture content, water solubility and oxygen transmission rate, whereas water absorption was increased. It was observed in micrographs that films with 1.5% SA and 1.0% GL had better surface attributes, and a further increase in GL and decrease in SA concentration was not found to be as favorable. Furthermore, FTIR spectra exhibited that intermolecular hydrogen bonding occurred between GL and OP-SA. X-ray diffraction showed that the films crystal structure has been changed significantly when the OP-SA and GL were mixed in. The plasticized films showed higher thermal stability as confirmed by TGA and DSC thermogram. The tensile strength of OP-SA-GL films was enhanced from 0.92 to 7.39 MPa, while elongation at break was decreased significantly from 20.76 to 2.67%. Consequently, orange peel-alginate-glycerol films could potentially be implemented in the food packaging. [ABSTRACT FROM AUTHOR]

Acute generalized exanthematous pustulosis (AGEP) is a severe cutaneous adverse reaction, typically characterized by the appearance of multiple pinpoint non-follicular pustules, less than 5 mm, sterile, on an erythematous-edematous base, and can be disseminated. Up to 90% of cases are associated with drug administration. It usually resolves in less than 15 days with a good prognosis. We describe the case of a 31-year-old man who experienced drug-induced AGEP with multisystem involvement. However, at the onset, he presented with purpuric lesions on the skin and oral mucosal involvement, leading to the consideration of other differential diagnoses. The clinical evolution, including pustule formation and histopathological findings, led to the diagnosis of AGEP. He received standard supportive care, including topical and systemic corticosteroids, with a favorable clinical outcome. This case highlights an atypical presentation of AGEP and the possibility of overlap with other drug adverse reactions, emphasizing the need for timely and accurate diagnosis and management.

Background: High-risk human papilloma virus (HR-HPV) is highly prevalent in sexually active men and women; HR-HPV has been classified as a sexually transmitted infection (STI) and as a necessary, but not sufficient, causal agent for cervical cancer. Women who test positive for HPV often experience serious psychosocial consequences such as fear, shame, fatalism and stigmatisation, as the result of popular perceptions of questionable moral and sexual conduct. To improve this situation, public health sector HPV communication and education strategies need to be improved. Objective: To evaluate the HPV communicative education strategies used in a pilot study for cervical cancer screening in Colombia using the HPV DNA test. Methodology: Analytic, qualitative research involving 10 focus groups (FGs) with women 30-65 years of age, grouped according to their test results (positive or negative) and age (younger or older than 50 years). Women participated in HPV communication and educational activities which included radio announcements, cartoon novel story books, flip charts and face-to-face communication. Content analysis of FGs discussions was conducted. Results: After participating in HPV communication and education activities, women were unable to differentiate clearly between infection and disease. HPV-negative women classified HPV as dangerous, primarily due to the vaccine communication strategies. The most remembered media were the cartoon novel story books, from which women were able to recall more details about the love story content than about the natural history of HPV. HPV-positive women felt afraid and fatalistic regarding their own HPV infection; face-to-face communication alleviated their anxiety and helped them recognise an HPV-positive report as good news. Conclusion: High-quality HPV vaccine communication strategies need to be implemented alongside screening messages. Face-to-face communication proved to be the most effective strategy for reducing the burden of stigmatisation among HPV-positive women, but timing is an essential component of communication.

This article reviews the current scenario and the main uncertainties and challenges associated with implementing Sustainable Aviation Fuel (SAF) in Colombia, from which it determines the possible certified technologies under the ASTM D 7566 standard as well as co-processing technologies contemplated within the ASTM D 1655 standard, more suitable for the implementation of SAF production. Likewise, through the PESTEL tool (Political, Economic, Social, Technological, Environmental, and Legal), a diagnosis is made in order to obtain an updated overview of the implementation of SAF in Colombia. Based on the above, it provides recommendations to mitigate the uncertainties identified, and it is complemented by the ECOCANVAS tool, which applies to businesses related to the circular economy, and also include the net production potential of SAF in Colombia, considering the production of feedstock, in agricultural residue of sugarcane, oil palm, corn, and coffee. This study concludes with some policy recommendations that can make SAF implementation viable and allow responsible institutions to organize themselves for better strategic action and identify the fields of research and the need for investment in R + D + i to strengthen the supply chain.
