Nurse-Led Approaches to Lowering Alcohol Use among Adolescents: Study Findings.

This study delves into how motivational sessions and brief interventions impact students' alcohol consumption, highlighting the vital role of nurses in fostering positive behavioural changes. The study aims to discern the effects of these interventions, starting with a pre-and post-intervention setup involving 62 students from a private school in northern Portugal. The intervention comprised a session delivered by school and mental health nurses, utilizing the motivational intervention and FRAMES method and a poster offering feedback on alcohol consumption scores. The results indicated that females tended to drink for fewer days and engage in less binge drinking than males. Furthermore, the intervention hinted at a reduction in the number of heavy drinking days. This study underscores the importance of including healthcare professionals, particularly nurses, in delivering brief interventions within school settings. The findings carry weight for crafting evidence-based interventions to cultivate healthier adolescent behaviours and enhance overall well-being.

Milligram scale enantioresolution of promethazine and its main metabolites, determination of their absolute configuration and assessment of enantioselective effects on human SY-SY5Y cells.

The misuse of pharmaceuticals has significantly increased in recent decades, becoming a major public health concern. The risks associated with medication misuse are particularly high in cases of overdose, especially when the active substances are chiral, as enantioselectivity plays an important role in toxicity. Promethazine (PMZ) is a chiral antihistamine marketed as a racemate and it is misused in "Purple Drank", a recreational drug beverage, that combines codeine and/or PMZ, with soda or alcohol leading to serious health consequences and fatalities in consumers around the world, particularly among teenagers. Information regarding the enantioselectivity in the toxicity of (R,S)-PMZ and its main metabolites, namely promethazine sulfoxide (PMZSO) and desmonomethyl promethazine (DMPMZ), is unknown. This work reported, for the first time, the enantioseparation, in milligram scale, of (R,S)-PMZ, (R,S)-DMPMZ, (R,S)- PMZSO and the determination of their absolute configurations by electronic circular dichroism (ECD). The enantioseparation of all the six enantiomers was accomplished in a homemade semi-preparative column with amylose tris-3,5-dimethylphenylcarbamate (AD) coated with aminopropyl Nucleosil silica. The enantiomeric purity was evaluated using the analytical Lux® 3 µm i-Amylose-3 column, yielding enantiomeric purity values ranging between 94.4% and 99.7%. The elution order of all the enantiomers was accomplished combining the ECD results with an optical rotation detector. The elution order of the enantiomers was influenced only by the chiral selector, rather than the mobile phase. The cytotoxicity of the racemates and the isolated enantiomers towards differentiated SH-SY5Y cells was evaluated. (R,S)-DMPMZ exhibited a significantly higher cytotoxicity than (R,S)-PMZ, suggesting the metabolic bioactivation of (R,S)-PMZ. Conversely, no significant cytotoxicity was found for (R,S)-PMZSO, underscoring a metabolic detoxification pathway. Remarkably, enantioselectivity was observed for the cytotoxicity of PMZ; (R)-PMZ was significantly more cytotoxic than (S)-PMZ. The results underscore the importance to isolate the enantiomers in their enantiomerically form and their correct identification for toxicity enantioselectivity studies, which are vital to understand the drug's behaviour and safety, especially in case of overdoses.

Game4NurseSupervisor: Development of a board game for nursing mentoring.

AIM: To describe the stages of developing a board game prototype to promote knowledge about nursing mentorship. BACKGROUND: Clinical supervision in nursing is a vital strategy for the quality of care. The use of gamification through a board game can enhance knowledge about mentoring in nursing. DESIGN: We present a pilot study describing the development phases of the board game "Game4NurseSupervisor®." METHODS: The study comprised three phases. The first phase involved a modified e-Delphi study with experts to collect and validate the content to be integrated into the board game. The second phase focused on constructing the prototype of the board game. Finally, the third phase involved testing the prototype in sessions held in two healthcare units, followed by an evaluation through a questionnaire. RESULTS: The e-Delphi study, involving a panel composed of 59 experts, progressed through two rounds, resulting in 61 cards divided into four categories. The second phase involved constructing the board game, incorporating interactive elements such as "Game4NurseSupervisor®." In the third phase, 25 nurses, consisting of clinical practice nurses, participated in the testing phase and expressed satisfaction with the game. Highlighted benefits included reflective, playful, dynamic, interactive and educational aspects. CONCLUSIONS: The conclusions suggest that "Game4NurseSupervisor®" could be a valuable tool for promoting knowledge about nursing mentorship, providing an innovative and interactive approach to skill development. This study makes a valuable contribution by addressing a previously unexplored aspect of nurse mentor training: the potential of board games.

The role of venom proteomics and single-domain antibodies for antivenoms: Progress in snake envenoming treatment.

Single-domain antibodies (sdAbs) hold promise for developing new biopharmaceuticals to treat neglected tropical diseases (NTDs), including snakebites, which are severe and occur frequently. In addition, limitations of conventional snakebite treatments, especially in terms of local action, and the global antivenom crisis incentivize the use of this biotechnological tool to design next-generation snakebite antivenoms. Conventional antivenoms for snakebite treatment are usually composed of immunoglobulin G or F(ab')2 fragments derived from the plasma of immunized animals. sdAbs, the smallest antigen-binding fragments, are derived from the variable domains of camelid heavy-chain antibodies. sdAbs may have some advantages over conventional antivenoms for local toxicity, such as better penetration into tissues due to their small size, and high solubility and affinity for venom antigens due to their unique antigen-binding loops and ability to access cryptic epitopes. We present an overview of current antivenom therapy in the context of sdAb development for toxin neutralization. Furthermore, strategies are presented for identifying snake venom's major toxins as well as for developing antisnake toxin sdAbs by employing proteomic tools for toxin neutralization.

Impact of Exergames on the Rehabilitation of Cancer Patients Undergoing Major Abdominal Surgery: A Randomized Controlled Trial.

BACKGROUND: Exergames can be an appealing strategy that is integrated into post-abdominal surgery rehabilitation. OBJECTIVE: The aim of this study was to assess the effectiveness of exergame rehabilitation in improving independence in activities of daily living (ADLs) and patient balance after abdominal cancer surgery. METHODS: A randomized control-group study was carried out in an oncological hospital in Portugal. Seventy postoperative patients were included, and data collection took place between January 2023 and May 2023. The patients were randomly assigned to either an exergame rehabilitation program (n = 35) or a traditional rehabilitation program (n = 35). The assessed outcomes were the Barthel and Berg scales, and data collection occurred at 3 different time points: admission, 48 hours postoperatively, and on the seventh day after surgery. RESULTS: At the third assessment, a statistically significant difference was observed between the 2 groups for both indicators, ADLs and balance. CONCLUSIONS: There was an improvement in ADLs and balance in the exergames group. By the seventh day after surgery, the intervention group showed improvement in balance and ADLs compared with the control group. IMPLICATIONS FOR PRACTICE: The use of exergames can be a solution to the challenges of traditional rehabilitation methods after abdominal surgery for cancer for postoperative patients. This is the first study carried out in this specific population.

Evaluation of Antitumor Activity of Xanthones Conjugated with Amino Acids.

Cancer is a complex disease characterized by several alterations, which confer, to the cells, the capacity to proliferate uncontrollably and to resist cellular death. Multiresistance to conventional chemotherapy drugs is often the cause of treatment failure; thus, the search for natural products or their derivatives with therapeutic action is essential. Chiral derivatives of xanthones (CDXs) have shown potential inhibitory activity against the growth of some human tumor cell lines. This work reports the screening of a library of CDXs, through viability assays, in different cancer cell lines: A375-C5, MCF-7, NCI-H460, and HCT-15. CDXs' effect was analyzed based on several parameters of cancer cells, and it was also verified if these compounds were substrates of glycoprotein-P (Pgp), one of the main mechanisms of resistance in cancer therapy. Pgp expression was evaluated in all cell lines, but no expression was observed, except for HCT-15. Also, when a humanized yeast expressing the human gene MDR1 was used, no conclusions could be drawn about CDXs as Pgp substrates. The selected CDXs did not induce significant differences in the metabolic parameters analyzed. These results show that some CDXs present promising antitumor activity, but other mechanisms should be triggered by these compounds.

Primary intestinal-type adenocarcinoma: Report of a rare case involving a young patient.

The aim of this report was to describe a rare example of sporadic intestinal-type adenocarcinoma of the major salivary glands and oral cavity. A 23-year-old female patient presented an asymptomatic, progressive-growing mass involving the floor of mouth and the left submandibular gland. Fine-needle aspiration cytology, imaging exams, and surgical specimen findings were consisted with the diagnosis of primary intestinal-type adenocarcinoma, despite its similar immunohistochemical results with colorectal adenocarcinoma. Adjuvant chemotherapy and radiotherapy were performed, but the patient developed multiple metastatic lesions after one year of initial the intervention and deceased following 13 months of follow-up, despite several therapeutic efforts. We verified that sporadic cases of primary intestinal-type adenocarcinoma still lack information regarding etiology and tumorigenesis, especially in young and females. A complete diagnostic workflow is indispensable to rule out the presence of primary colorectal adenocarcinoma.

Malignant tumors affecting the head and neck region in ancient times: Comprehensive study of the CRAB Database.

In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world.

Healthcare Experience of People with Acute Spinal Cord Injury: A Phenomenological Study.

Living with spinal cord injury (SCI) is a challenge that begins in the acute phase, when the disease, the limitations, and the treatments fill the days at the hospital. This study aims to understand the healthcare experience of the person with SCI in the acute phase, based on the Activities of Living Nursing Model (ALNM). It is a qualitative and phenomenological study based on the Standards for Reporting Qualitative Research. Data were collected via semi-structured interviews. Content analysis was performed using the ATLAS.ti software and Bardin's methodology. The article was written following the COREQ guidelines. The categories were defined using the Roper-Logan-Tierney Model for Nursing. The sample included 16 people with incomplete SCI, different etiology, and neurological levels. Eleven of the twelve ALNM emerged from the interviews. The activities of mobilizing, eliminating, maintaining a safe environment, and communicating were emphasized the most. Controlling body temperature was not relevant. Mobility deficits and pain increased dependence. Feelings of motivation, encouragement, and frustration were highlighted. Professional expertise, rehabilitation resources, and support equipment promoted independence. The results in this sample revealed that people with SCI in the acute phase have complex challenges related to dependence awareness and treatments, but they always keep recovery expectations in mind.

Therapeutic Potential of Marine-Derived Cyclic Peptides as Antiparasitic Agents.

Parasitic diseases still compromise human health. Some of the currently available therapeutic drugs have limitations considering their adverse effects, questionable efficacy, and long treatment, which have encouraged drug resistance. There is an urgent need to find new, safe, effective, and affordable antiparasitic drugs. Marine-derived cyclic peptides have been increasingly screened as candidates for developing new drugs. Therefore, in this review, a systematic analysis of the scientific literature was performed and 25 marine-derived cyclic peptides with antiparasitic activity (1-25) were found. Antimalarial activity is the most reported (51%), followed by antileishmanial (27%) and antitrypanosomal (20%) activities. Some compounds showed promising antiparasitic activity at the nM scale, being active against various parasites. The mechanisms of action and targets for some of the compounds have been investigated, revealing different strategies against parasites.

Validation of the Comprehensive Feeding Practices Questionnaire (CFPQ) with Portuguese Caregivers of 2-to-8-Year-Olds.

Recent findings have demonstrated an increase in the prevalence of childhood obesity and overweight in Portugal, urging the need to study modifiable risk factors such as parental feeding practices. The Comprehensive Feeding Practices Questionnaire (CFPQ) is an important self-report measure assessing a broad range of responsive and non-responsive feeding practices. However, the CFPQ has not yet been validated in Portugal. Therefore, the present study aimed to test the validity of this measure with Portuguese parents of 2-to-8-year-old children. A sample of 409 parents completed a Portuguese-adapted version of the CFPQ and the already validated Child Feeding Questionnaire (CFQ). Confirmatory factor analysis (CFA), exploratory factor analysis (EFA), and psychometric analysis were conducted. CFA demonstrated the original 12-factor structure did not fit the sample. EFA identified an eight-factor structure comprising 29 items: Monitoring, Modeling, Environment, Involvement, Emotion Regulation, Restriction for Weight Control, Restriction for Health, and Pressure. Findings suggest that parental feeding practices are sensitive to parents' background cultures and children's developmental period.

Peptides from Marine-Derived Fungi: Chemistry and Biological Activities.

Marine natural products are well-recognized as potential resources to fill the pipeline of drug leads to enter the pharmaceutical industry. In this circumstance, marine-derived fungi are one of the unique sources of bioactive secondary metabolites due to their capacity to produce diverse polyketides and peptides with unique structures and diverse biological activities. The present review covers the peptides from marine-derived fungi reported from the literature published from January 1991 to June 2023, and various scientific databases, including Elsevier, ACS publications, Taylor and Francis, Wiley Online Library, MDPI, Springer, Thieme, Bentham, ProQuest, and the Marine Pharmacology website, are used for a literature search. This review focuses on chemical characteristics, sources, and biological and pharmacological activities of 366 marine fungal peptides belonging to various classes, such as linear, cyclic, and depsipeptides. Among 30 marine-derived fungal genera, isolated from marine macro-organisms such as marine algae, sponges, coral, and mangrove plants, as well as deep sea sediments, species of Aspergillus were found to produce the highest number of peptides (174 peptides), followed by Penicillium (23 peptides), Acremonium (22 peptides), Eurotium (18 peptides), Trichoderma (18 peptides), Simplicillium (17 peptides), and Beauveria (12 peptides). The cytotoxic activity against a broad spectrum of human cancer cell lines was the predominant biological activity of the reported marine peptides (32%), whereas antibacterial, antifungal, antiviral, anti-inflammatory, and various enzyme inhibition activities ranged from 7% to 20%. In the first part of this review, the chemistry of marine peptides is discussed and followed by their biological activity.

Digitisation of patient preferences in palliative care: mobile app prototype.

BACKGROUND: Engaging in advance care planning can be emotionally challenging, but gamification and technology are suggested as a potential solution. OBJECTIVE: Present the development stages of a mobile app prototype to improve quality of life for patients in palliative care. DESIGN: The study started with a comprehensive literature review to establish a foundation. Subsequently, interviews were conducted to validate the proposed features of the mobile application. Following the development phase, usability tests were conducted to evaluate the overall usability of the mobile application. Furthermore, an oral questionnaire was administered to understand user satisfaction about the implemented features. RESULTS: A three-phase testing approach was employed based on the chosen user-centred design methodology to obtain the results. Three iterations were conducted, with improvements being made based on feedback and tested in subsequent phases. Despite the added complexity arising from the health status of patients in palliative care, the usability tests and implemented features received positive feedback from both patients and healthcare providers. CONCLUSION: The research findings have demonstrated the potential of digitisation in enhancing the quality of life for patients in palliative care. This was achieved through the implementation of patient-centred design, personalised care, the inclusion of social chatrooms and facilitating end-of-life discussions.

A scoping review of mobile apps for use with palliative patients in the context of home care.

CONTEXT: Progress in mobile technology, especially the use of applications for mobile devices, can support the process of monitoring patients in palliative care (therapeutics), controlling symptoms, or providing self-care guidelines for the user, namely patients or caregivers. OBJECTIVES: To map the available knowledge regarding the use of applications for mobile devices to support adult patients in palliative care at home. METHODS: Literature review, based on the Joanna Briggs Institute model(s) for Scoping Review. All articles published until October 27, 2022, were identified in the electronic databases MEDLINE®, CINAHL®, Psychology and Behavioral Sciences Collection, Cochrane Library, and Scopus using the respective Boolean logical operators and key terms. RESULTS: A total of 634 articles were identified, and a final 24 studies were included. Eleven mobile device applications were identified, demonstrating different aspects of design, use, and technological development. These have incorporated the most recent technology in their functionalities. CONCLUSION: Mobile applications can be considered a viable and effective means of monitoring patients in palliative care. However, these applications must go beyond the academic scenario in which they were developed and move toward widespread use in practice, allowing the evaluation of the impact of this "new" intervention modality to understand their effectiveness and the application of best practices.

The altered metabolic pathways of diffuse large B-cell lymphoma not otherwise specified.

Altered metabolic fingerprints of Diffuse large B-cell lymphoma, not otherwise specified (DLBCL NOS) may offer novel opportunities to identify new biomarkers and improve the understanding of its pathogenesis. This study aimed to investigate the modified metabolic pathways in extranodal, germinal center B-cell (GCB) and non-GCB DLBCL NOS from the head and neck. Formalin-fixed paraffin-embedded (FFPE) tissues from eleven DLBCL NOS classified according to Hans' algorithm using immunohistochemistry, and five normal lymphoid tissues (LT) were analyzed by high-performance liquid chromatography-mass spectrometry-based untargeted metabolomics. Partial Least Squares Discriminant Analysis showed that GCB and non-GCB DLBCL NOS have a distinct metabolomics profile, being the former more similar to normal lymphoid tissues. Metabolite pathway enrichment analysis indicated the following altered pathways: arachidonic acid, tyrosine, xenobiotics, vitamin E metabolism, and vitamin A. Our findings support that GCB and non-GCB DLBCL NOS has a distinct metabolomic profile, in which GCB possibly shares more metabolic similarities with LT than non-GCB DLBCL NOS.

Single-domain antibodies applied as antiviral immunotherapeutics.

Viral infections have been the cause of high mortality rates throughout different periods in history. Over the last two decades, outbreaks caused by zoonotic diseases and transmitted by arboviruses have had a significant impact on human health. The emergence of viral infections in different parts of the world encourages the search for new inputs to fight pathologies of viral origin. Antibodies represent the predominant class of new drugs developed in recent years and approved for the treatment of various human diseases, including cancer, autoimmune and infectious diseases. A promising group of antibodies are single-domain antibodies derived from camelid heavy chain immunoglobulins, or VHHs, are biomolecules with nanometric dimensions and unique pharmaceutical and biophysical properties that can be used in the diagnosis and immunotherapy of viral infections. For viral neutralization to occur, VHHs can act in different stages of the viral cycle, including the actual inhibition of infection, to hindering viral replication or assembly. This review article addresses advances involving the use of VHHs in therapeutic propositions aimed to battle different viruses that affect human health.
