High Pressure, Low Control: The Challenging Side Of Resistant Arterial Hyperten...
Caetano Coelho, Mariana; Silva, Adriana; Figueiredo, Margarida; Paula, SofiaArterial hypertension constitutes a highly prevalent cardiovascular risk factor in the global population. However, a significant portion of patients fails to achieve adequate blood pressure levels for effective risk control, challenging medical practice. Resistant hypertension is identified when the patient maintains blood pressure levels above the recommended value, even with the concurrent use of three anti-h...
Resistome, Virulome, and Clonal Variation in Methicillin-Resistant (MRSA) in He...
Silva, Vanessa; Silva, Adriana; Barbero, Raquel; Romero, Mario; Del Campo, Rosa; Caniça, Manuela; Cordeiro, Rui; Igrejas, Gilberto; Poeta, PatriciaThis cross-sectional study investigates the methicillin-resistant (MRSA): its prevalence, antimicrobial resistance, and molecular characteristics in healthy swine populations in central Portugal. A total of 213 samples were collected from pigs on twelve farms, and MRSA prevalence was assessed using selective agar plates and confirmed via molecular methods. Antimicrobial susceptibility testing and whole genome s...
Listeria monocytogenes from Food Products and Food Associated Environments: Ant...
Silva, Adriana; Silva, Vanessa; Gomes, João Paulo; Coelho, Anabela; Batista, Rita; Saraiva, Cristina; Esteves, Alexandra; Martins, ÂngelaListeria monocytogenes, a foodborne pathogen, exhibits high adaptability to adverse environmental conditions and is common in the food industry, especially in ready-to-eat foods. L. monocytogenes strains pose food safety challenges due to their ability to form biofilms, increased resistance to disinfectants, and long-term persistence in the environment. The aim of this study was to evaluate the presence and gen...
Unveiling Antibiotic Resistance, Clonal Diversity, and Biofilm Formation in Iso...
Silva, Adriana; Silva, Vanessa; Dapkevicius, Maria de Lurdes Enes; Azevedo, Mónica; Cordeiro, Rui; Pereira, José Eduardo; Valentão, PatríciaEscherichia coli, a commensal microorganism found in the gastrointestinal tract of human and animal hosts, plays a central role in agriculture and public health. Global demand for animal products has promoted increased pig farming, leading to growing concerns about the prevalence of antibiotic-resistant E. coli strains in swine populations. It should be noted that a significant portion of antibiotics deployed i...
Comprehensive typing and genetic analysis of L. monocytogenes isolates: implica...
Silva, Adriana; Silva, Vanessa; Borges, Vítor; Coelho, Anabela; Batista, Rita; Esteves, Alexandra; Igrejas, Gilberto; Saraiva, CristinaListeria species are commonly found in various environments and contaminated food, with livestock serving as a significant source of foodborne pathogens. Among these species, Listeria monocytogenes (L. monocytogenes) is particularly noteworthy as it can affect both livestock and humans. Antibiotics are frequently used in food animals for disease treatment and prevention on a large scale. This practice can lead ...
COVID-19 vaccine effectiveness among healthcare workers: a hospital-based cohor...
Gaio, Vânia; Santos, Ana João; Amaral, Palmira; Faro Viana, João; Antunes, Isabel; Pacheco, Vânia; Paiva, Artur; Pinto Leite, PedroObjectives Healthcare workers (HCWs) were the first to be prioritised for COVID-19 vaccination. This study aims to estimate the COVID-19 vaccine effectiveness (VE) against SARS-CoV- 2 symptomatic infection among HCWs in Portuguese hospitals. Design Prospective cohort study. Setting and participants We analysed data from HCWs (all professional categories) from three central hospitals: one in the Lisbon and Tagus...
Screening of chemical composition, antimicrobial and antioxidant activities in ...
Silva, Vanessa; Silva, Adriana; Ribeiro, Jessica; Aires, Alfredo; Carvalho, Rosa Paula; Amaral, Joana S.; Barros, Lillian; Igrejas, GilbertoAntimicrobial resistance is increasing globally and is now one of the major public health problems. Therefore, there is a need to search for new antimicrobial agents. The food industry generates large amounts of by-products that are rich in bioactive compounds, such as phenolic compounds, which are known to have several health benefits, including antioxidant and antimicrobial properties. Thus, we aimed to chara...
Exploring the role of gamification in the online shopping experience in retail ...
Lopes, João M.; Lopes, Pedro; Silva, Adriana; Lourenço, Daniel; Esteves, Duarte; Redondo, Valter; Gomes, SofiaOnline retail shops increasingly implement gamified marketing strategies to enrich con- sumers’ online experience and increase engagement. This study aims to evaluate the ludic experience of consumers in online retail stores and the role of gamification and game mechanics in changing the online shopping experience. It seeks to assess, through a qualitative methodology, based on an exploratory study approach obt...
Accidental Diagnosis of Isolated Persistent Left Superior Vena Cava After an El...
Coimbra, Miguel T; Braga, Beatriz; Silva, Adriana; Sousa, Fernanda; Queirós, JoséPersistent left superior vena cava (PLSVC) is the most frequent thoracic venous anatomical variant in the general population. Isolated PLSVC, without formation of the right superior vena cava, is described in 10% of cases of PLSVC only. While it can be associated with congenital heart disease, arrhythmias, and premature death, adult patients with PLSVC are mostly asymptomatic, and the diagnosis is usually accid...
Potencial cosmético de Artemisia campestris
Silva, Adriana; Pinho, Cláudia; Oliveira, Ana IsabelNos últimos anos, é evidente a importância das plantas medicinais e seus compostos no cuidado cutâneo. O género Artemisia é um dos maiores e mais amplamente distribuídos da família Asteraceae na Europa e no Norte de África, tendo desenvolvido várias estratégias para lidar com o elevado stress ambiental, como a síntese de moléculas altamente antioxidantes devido ao seu crescimento em condições desfavoráveis.
