- Nutritional and Bioactive Profiling of Cucumis melo L. By-Products: Towards a Circular Food EconomyPublication . Silva, Mafalda A.; Albuquerque, Tânia G.; Ferreira, Diana M.; Alves, Rita C.; Oliveira, Maria Beatriz P.P.; Costa, Helena S.Food waste, due to the high quantities produced, becomes a significant environmental, economic, and social challenge worldwide. Simultaneously, the rising prevalence of chronic diseases has intensified the demand for healthier food options. A promising approach to address these issues involves the valorisation of food by-products for the development of innovative and healthier food products. Cucumis melo L., commonly consumed as a fruit, generates peels and seeds that are typically discarded. In the present study, the nutritional composition and antioxidant potential of pulp, peel, and seeds of C. melo L. (yellow and green melon) were comprehensively evaluated. The seeds were identified as a rich source of dietary fibre (39.0 and 39.7 g/100 g dw; p > 0.05) and protein (21.0 and 21.3 g/100 g dw; p > 0.05), exhibiting an appealing fatty acid profile. The peel contains high levels of dietary fibre (39.7 and 47.1 g/100 g dw; p > 0.05) and total phenolic compounds (1976 and 2212 mg GAE/100 g dw; p > 0.05), suggesting significant bioactive potential. The peels showed a high antioxidant capacity for both methods used, DPPH• (120 and 144 mg TE/100 g dw; p > 0.05) and FRAP (6146 and 7408 mg TE/100 g dw; p > 0.05) assays. Potassium emerged as the predominant mineral in the seeds (799 and 805 mg/100 dw; p > 0.05), while glutamic acid was the most abundant amino acid (4161 and 4327 mg/100 g dw; p > 0.05). These findings emphasise the antioxidant and nutritional properties of C. melo L. by-products, highlighting their potential for inclusion in novel food formulations. This study not only advances the understanding of C. melo L. properties but also supports the reduction of food waste and promotes sustainability within the food supply chain.
- Spatial analysis of HPV infection and contextual factors associated with higher HPV prevalencePublication . Sousa, R.; Fonseca-Moutinho, J.A.; Gomes, F.; Loureiro, F.; Goes, A.R.; Soares, PatriciaObjectives: To identify areas with high rates of high-risk Papillomavirus (hrHPV) infection and associated contextual factors in the Centre Region of Portugal at the municipality level. Study design: We conducted an ecological study in 78 municipalities located in the Central Region of Portugal from March 2019 to December 2022. Methods: We used data from the cervical cancer screening (CCS) program database after switching to primary HPV testing. Demographic, socio-economic, and healthcare availability variables were extracted from official sources (Statistics Portugal and Central Region Health Administration Information Systems). Spatial analysis and logistic generalised linear models were used to identify areas of high hrHPV infection and associated contextual factors. Results: The overall hrHPV infection prevalence was 9.9 %. We found three significant clusters, predominantly in municipalities near major urban centres. These clusters were characterised by higher population density, a greater proportion of younger women, higher median income per inhabitant, a larger proportion of residents with graduate degrees, and increased availability of healthcare units. Conclusions: This study has uncovered the geographical distribution of hrHPV infection at the municipal level and highlights the contextual factors associated with higher prevalence. Identifying demographics and socio-economic predictors of high hrHPV infection could support public health programs by targeting interventions to specific populations and contexts. This might open up new scenarios for improving prevention and control strategies, offering more intensive screening in areas with the most urgent needs.
