- Attitudes toward community service among higher health sciences studentsPublication . Vicente, Sónia; Pereira, Ângela Maria; Vidal, Ana Cristina; Costa, Cláudia MariaUniversity Social Responsibility (USR) integrates academic goals with ethics, civic engagement, and sustainability. This study assessed community service attitudes among 529 higher health sciences students using the Portuguese Community Service Attitudes Scale. Although 52.9% reported prior volunteer experience, 75.2% had not participated in community service during university. An association was found between academic programme and prior involvement, particularly among Dental Medicine and Physiotherapy students. While no sex differences were observed, programme-specific trends suggest that practical training fosters stronger civic responsibility. Integrating structured, discipline-specific community service into curricula may enhance civic identity and better align education with sustainable development goals.
- An isothermal lab-on-phone test for easy molecular diagnosis of SARS-CoV-2 near patients and in less than 1 hourPublication . Doria, Gonçalo; Clemente, Carla; Coelho, Eduardo; Colaço, João; Crespo, Rui; Semikhodskii, Andrei; Mansinho, Helder; Dinis, Magno; Carvalho, Maria Fernanda; Casmarrinha, Manuela; Samina, Cátia; Vidal, Ana Cristina; Delarue, Francisca; Graúdo, Susana; Santos, Ana Catarina; Peças, David; Carreira, Olga; Marques, Raquel; Gaspar, Carina; Flores, OrfeuObjectives: The performance of a new point-of-care CE-IVD-marked isothermal lab-on-phone COVID-19 assay was assessed in comparison to a gold standard real-time reverse transcriptase–PCR method. Methods: The study was conducted following a nonprobability sampling of ≥16-year-old volunteers from three different laboratories, using direct mouthwash (N = 24) or nasopharyngeal (N = 191) clinical samples. Results: The assay demonstrated 95.19% sensitivity and 100% specificity for detection of SARS-CoV-2 in direct nasopharyngeal crude samples and 78.95% sensitivity and 100% specificity in direct mouthwash crude samples. It also successfully detected currently predominant SARS-CoV-2 variants of concern (Beta B.1.351, Delta B.1.617.2, and Omicron B.1.1.529) and demonstrated to be inert against potential cross-reactions of other common respiratory pathogens that cause infections that present similar symptoms to COVID-19. Conclusion: This lab-on-phone pocket-sized assay relies on an isothermal amplification of SARS-CoV-2’s N and E genes, taking just 50 minutes from sample to result, with only 2 minutes of hands-on time. It presents good performance when using direct nasopharyngeal crude samples, enabling a low-cost, real-time, rapid, and accurate identification of SARS-CoV-2 infections at the point of care, which is important for both clinical management and population screening, as a tool to break the chain of transmission of COVID-19 pandemic, especially in low-resources environments.
