- Online behaviours during the COVID-19 pandemic and their associations with psychological factors: an international exploratory studyPublication . Burkauskas, Julius; Dores, Artemisa RochaThis cross-sectional study aimed to explore specific online behaviours and their association with a range of underlying psychological and other behavioural factors during the COVID-19 pandemic. Eight countries (Italy, Spain, the United Kingdom, Lithuania, Portugal, Japan, Hungary, and Brazil) participated in an international investigation involving 2223 participants (M = 33 years old; SD = 11), 70% of whom were females. Participants were surveyed for specific type of Internet use severity, appearance anxiety, self-compassion, and image and use of performance-enhancing drugs (IPEDs). Results were compared cross-culturally. The mean time spent online was 5 h (SD = ±3) of daily browsing during the pandemic. The most commonly performed activities included social networking, streaming, and general surfing. A strong association between these online behaviours and appearance anxiety, self-compassion, and IPEDs use was found after adjustment for possible confounders, with higher scores being associated with specific online activities. Significant cross cultural differences also emerged in terms of the amount of time spent online during the initial stages of the COVID-19 pandemic.
- Life Cycle Assessment and Life Cycle Cost of an Innovative Carbon Paper Sensor for 17α-Ethinylestradiol and Comparison with the Classical Chromatographic MethodPublication . Martins, Florinda; Torrinha, Álvaro; Delerue-Matos, Cristina; Morais, SimoneNowadays there is a growing concern with the environment and sustainability, which means that better methods, including pollutants analysis, with less consumption of materials, organic solvents, and energy, need to be developed. Considering the almost inexistent information about the topic, the main goal of this work was to compare the environmental impacts of two analytical methods, a traditional one based on liquid chromatography with fluorescence detection and a newly developed carbon paper sensor. The selected analyte was 17α-ethinylestradiol, which is a contaminant of emergent concern in aquatic ecosystems due to its endocrine disruptor behavior. The life cycle assessment data showed that the sensor detection presents an almost negligible environmental impact when compared with the extraction step (the same for both methods) and the liquid chromatographic determination (roughly 80 times higher than with the sensor). The sensor values for all categories of damage are below 3% of the total method impacts, i.e., 1.6, 1.9, 2.4, and 2.9% for resources, climate change, human health, and ecosystem quality. The extraction represents 98.1% of the sensor environmental impacts (and 99.6% of its life cycle costing) and 38.8% of the chromatographic method. This study evidences the need of developing and applying greener analytical (detection and extraction) strategies
- Application of cryolipolysis in adipose tissue: A systematic reviewPublication . Resende, Leonor; Noites, Andreia; Amorim, ManuelaCryolipolysis is characterized by localized and controlled cooling of the subcutaneous adipose tissue, in a non-invasive way, causing a localized panniculitis, followed by adipocyte death by apoptosis and, consequently, a decrease in adipose tissue in the treated area. To evaluate the scientific evidence and methodological qualities about effects, adverse reactions, and level of satisfaction of cryolipolysis for the reduction of sub cutaneous adipose tissue. A systematic review was carried out according to the PRISMA recommen dation. Searches were conducted in different databases. We included studies that used a randomized control and self-control design and were carried out in humans. Articles published in English and Portuguese were screened, with no time limit regard ing the year of publication. The methodological quality of the studies was assessed using the Cochrane Rob2 scale. Of 381 articles, seven were considered eligible for inclusion. After applying the Cochrane Rob2 scale, five studies were included in the final sample. Most studies showed significant results for cryolipolysis in reducing localized fat. The incorpora tion of a dietary program into the treatment was shown to contribute to a significant improvement in the lipid profile and liver enzymes, which does not happen when cry olipolysis is applied in isolation. Rare adverse effects have been identified, but never persisting beyond a month. Cryolipolysis is an effective technique for reducing localized fat, safe, and well tolerated, with most participants satisfied at the end of the treatment. However, more randomized controlled studies should be carried out, since there is a limited number of articles with good methodological quality.
- At-distance neurocognitive rehabilitation during COVID-19 pandemic: A first glance of patients’ perspectives about the process and an online platformPublication . Geraldo, Andreia ; Dores, Artemisa R; Carvalho, Irene P.; Guerreiro, Sandra; Castro-Caldas, Alexandre; Barbosa, FernandoDespite the use of digital communication technologies in neurocognitive rehabilitation has been widely used in face-to-face interventions, the difficulties of using ICT-based tools to provide rehabilitation services and the unfamiliarity of the neuropsychologists with internet interventions limited the use of these kinds of interventions in their clinical practices. The lockdown and mitigating measures associated with the COVID-19 pandemic, on the other hand, forced the use of at-distance and online interventions as a means to mitigate the impact of those measures on the mental health and rehabilitation processes of people with neurological disorders. Overall, little is known about the perspectives of patients with acquired neurological conditions about rehabilitation services delivered at distance. Therefore, the main goal of this study was to explore the perceptions that patients with neurological disorders have on at-distance online neurocognitive rehabilitation, namely during the COVID-19 pandemic. Sixteen patients with acquired neurological conditions attending an online neurocognitive rehabilitation program in a Portuguese rehabilitation center filled in an online questionnaire during the mandatory lockdown. The results of this study highlight the potential of delivering rehabilitation services at distance, presenting its advantages and limitations from patients’ perspectives, as well as suggestions for improving both neurorehabilitation processes and the online rehabilitation platform used.
- Dilema de Cassandra: do desperdício ao figurino para uma encenação impossívelPublication . Santos, Jordann dos; Rocha, Maria Manuela Bronze daExploro neste projeto a questão da fisicalidade formal do alerta – através do resgate de resíduos da indústria têxtil, responsabilizada por representar uma das maiores poluentes mundiais, em consequência da globalização e do aumento do consumo acelerado. Pretendo questionar a temática da sustentabilidade através da manipulação de vestígios invisíveis do processo industrializado da construção do vestuário, considerando a questão morfológica da sua existência. Utilizando como ponto de partida a personagem profética de Cassandra – subtraída da mitologia grega. Para sustentar o deslocamento espectral e objetual do figurino, na procura da sua teatralidade, chego a uma encenação impossível para questionar o lugar do figurinista na produção do gestus social numa produção artística.
