    Abstract Introduction: Indirect carotid-cavernous fistula (CCF) can lead to secondary glaucoma, posing significant treatment challenges. This paper discusses a case where standard embolization failed, and an Ahmed FP7 valved glaucoma tube shunt was crucial for managing the increased intraocular pressure (IOP), highlighting the necessity for individualized surgical approaches.
    Case presentation: A 48-year-old female presented in the emergency department with conjunctival hyperemia, proptosis and elevated IOP; initial imaging findings were indicative of orbital inflammatory disease. Further evaluation with cerebral CT angiography revealed a possible CCF. Subsequent angiography confirmed an indirect CCF type D, leading to the patient undergoing endovascular embolization. Final monitoring revealed a subtotal occlusion of the fistula. Although there was some improvement post-procedure, IOP remained elevated despite medication, and subsequent attempts of embolization were unsuccessful. Surgical intervention with a tube shunt was performed, allowing IOP to decreased to a normal range. Optic nerve head optical coherence tomography, standard automated perimetry, and best-corrected visual acuity remained stable during the 33-month follow-up.
    Discussion: In managing glaucoma linked to CCF, a multidisciplinary approach is critical. Conservative methods are often adequate, with spontaneous CCF closure observed in a significant percentage. Endovascular embolization is reserved for refractory cases, with embolization showing a higher rate of IOP normalization compared to medication alone. Yet, when fistula closure is challenging or contraindicated, individualized management strategies like glaucoma surgery may be employed.
    Conclusions: When fistula closure is not achievable, the Ahmed FP7 valved tube shunt can successfully regulate IOP with minimal complications, providing an effective alternative for refractory cases.

    Abstract Colorectal cancer (CRC) is one of the most common malignancies and one of the leading causes of cancer-related death worldwide, urging the need for new and more efficient therapeutic approaches. Ruthenium complexes have emerged as attractive alternatives to traditional platinum-based compounds in the treatment of CRC. This work aims to evaluate anti-CRC properties, as well as to identify the mechanisms of action of ruthenium complexes with the general formula [Ru(η

    Abstract Screen time and the use of social networks is the most frequent form of leisure time occupation and socializing for adolescents. The present study is aimed at understanding and characterizing, from an ecological perspective, what distinguishes healthy and less healthy or even dependent use of social media in young people and the influence on adolescents' well-being. This paper is based on the Health Behaviour in School-aged Children (HBSC) from 2022, a survey carried out every 4 years, in collaboration with the World Health Organisation (WHO), following an international protocol. A total of 7643 students from the 6th, 8th, 10th, and 12th school grades responded, of which 53.9% were female, with an average age of 15.05 (

    Abstract Carotenoids are tetraterpenoids molecules present in all photosynthetic organisms, responsible for better light-harvesting and energy dissipation in photosynthesis. In cyanobacteria, the biosynthetic pathway of carotenoids is well described, and apart from the more common compounds (e.g., β-carotene, zeaxanthin, and echinenone), specific carotenoids can also be found, such as myxoxanthophyll. Moreover, cyanobacteria have a protein complex called orange carotenoid protein (OCP) as a mechanism of photoprotection. Although cyanobacteria are not the organism of choice for the industrial production of carotenoids, the optimisation of their production and the evaluation of their bioactive capacity demonstrate that these organisms may indeed be a potential candidate for future pigment production in a more environmentally friendly and sustainable approach of biorefinery. Carotenoids-rich extracts are described as antioxidant, anti-inflammatory, and anti-tumoral agents and are proposed for feed and cosmetical industries. Thus, several strategies for the optimisation of a cyanobacteria-based bioprocess for the obtention of pigments were described. This review aims to give an overview of carotenoids from cyanobacteria not only in terms of their chemistry but also in terms of their biotechnological applicability and the advances and the challenges in the production of such compounds.

    Abstract Objective: To evaluate if EEG patterns considered highly malignant are reliable predictors not only of poor neurological outcome but also reliable predictors of death.
    Methods: Retrospectively, EEGs from Cardiac Arrest (CA) patients of two teaching hospitals in Lisbon were classified into 3 groups: highly malignant, malignant, and benign groups. Outcome was assessed at 6 months after CA by CPC (Cerebral Performance Categories) scale. We evaluated the accuracy of these patterns to predict poor neurological outcome and death.
    Results: We included 106 patients for analysis. All patients with a highly malignant EEG (n = 37) presented a poor neurological outcome. Those patterns were also associated with death. Malignant EEG patterns were not associated with poor neurological outcome. Benign EEG patterns were associated with good neurological recovery (p < 0.0001).
    Conclusion: Highly malignant EEG patterns were strongly associated with poor neurological outcome and can be considered to be predictors of death.
    Significance: This study increased the knowledge about the value of EEG as a tool in outcome prediction of patients after cardiac arrest.

    Abstract An unbalanced diet is one of the well-known risk factors for the development of colorectal cancer (CRC). This type of cancer is currently the main cause of cancer-related deaths worldwide, urging the need for new and more effective preventive and therapeutic approaches. It is already known that CRC patients have alterations in the microbial community and metabolism. In this regard, a concept that has been recently attracting the attention of the scientific community is the development of functional food or nutraceuticals, as a new and more effective strategy to overcome CRC patient-associated dysbiosis. Particularly, dairy product enriched diets are the major dairy source of dietary calcium, vitamin D and folate intake, which are well-known to have a protective effect against CRC development. In addition, these products are rich in both pre- and probiotics, constituting a double strategy to modulate both the intestinal microbiota composition and the production of microbial metabolites. Short-chain fatty acids (SCFA), namely, acetate, butyrate, and propionate, are major contributors to colonic homeostasis since they regulate several biological and metabolic processes. In this review, we performed a state of art study concerning the use of dietary patterns, specifically the dairy-derived diet, in the modulation of the human microbiota and their potential use as pre-, pro- or synbiotics for the development of new preventive and therapeutic strategies for CRC.

    Abstract The present research is based on a large and representative national survey and intends to analyse the correlation of several leisure activities with risk, and with health and well-being outcomes. This work is part of the Health Behaviour in School-aged Children (HBSC) study, a collaborative WHO international study that aims to explore the school-aged children behaviour regarding health and risk behaviours in their life contexts. Participants were 8215 Portuguese adolescents, randomly chosen from those attending the 6th, 8th, 10th and 12th grades in 2018. The sample included 52.7% of girls and the mean age was 14.36 years old. Descriptive and comparative analyses were performed (ANOVAS and Chi-Square). The results of the present study suggested that several leisure activities, namely sports and social engagement activities (politic involvement and participation, religious activities, scouting and volunteer work), are associated with the adolescents' well-being and life satisfaction. However, these types of activities can also be associated with an increase in substance use. However, some activities are also associated with risky behaviour. Identifying activities that promote well-being in young people can be important for professionals, families and public policies.
