RESUMEN

Background: Family is a crucial social institution in end-of-life care. Family caregivers are encouraged to take on more responsibility at different times during the illness, providing personal and medical care. Unpaid work can be overburdening, with women often spending more time in care work than men. Objectives: This study explored multiple views on the family's role in end-of-life care from a critical perspective and a relational autonomy lens, considering gender in a socio-cultural context and applying a relational autonomy framework. It explored patients, relatives and healthcare providers' points of view. Design: This qualitative study was part of the iLIVE project, involving patients with incurable diseases, their relatives and health carers from hospital and non-hospital sites. Methods: Individual interviews of at least five patients, five relatives and five healthcare providers in each of the 10 participating countries using a semi-structured interview guide based on Giger-Davidhizar-Haff's model for cultural assessment in end-of-life care. Thematic analysis was performed initially within each country and across the complete dataset. Data sources, including researchers' field notes, were translated into English for international collaborative analysis. Results: We conducted 158 interviews (57 patients, 48 relatives and 53 healthcare providers). After collaborative analysis, five themes were identified across the countries: family as a finite care resource, families' active role in decision-making, open communication with the family, care burden and socio-cultural mandates. Families were crucial for providing informal care during severe illness, often acting as the only resource. Patients acknowledged the strain on carers, leading to a conceptual model highlighting socio-cultural influences, relational autonomy, care burden and feminisation of care. Conclusion: Society, health teams and family systems still need to better support the role of family caregivers described across countries. The model implies that family roles in end-of-life care balance relational autonomy with socio-cultural values. Real-world end-of-life scenarios do not occur in a wholly individualistic, closed-off atmosphere but in an interpersonal setting. Gender is often prominent, but normative ideas influence the decisions and actions of all involved.

RESUMEN

Punch grafting is a technique that can improve and accelerate the healing of hard-to-heal wounds and reduce the associated pain. It is a simple and inexpensive procedure that can be performed in the examination room. It is a technique that uses small split-thickness skin grafts (STSG) to promote the growth of epithelial tissue. It has been described as being used mainly to treat ulcers of venous, arterial, hypertensive and diabetic aetiology. Punch grafting has also been used successfully in postoperative dermatological surgical wounds. This article describes and details the performance of the punch-graft technique, with special emphasis on aftercare and the role of nurses in the procedure. A clinical case is presented of a patient who underwent surgery for cutaneous squamous cell carcinoma and whose primary closure was rejected. It was decided to place the STSGs obtained from the anterior aspect of the patient's thigh after preparation of the recipient area to ensure an optimal wound bed. The patient's pain subsided within a few days, and the wound healed within weeks with weekly dressing changes.

RESUMEN

The prospect of death influences people's thoughts about and how they deal with their remaining time. We aimed to understand whether patients with progressive, life-limiting diseases are oriented in the past, present, or future and how they deal with temporality. We conducted 57 in-depth interviews with end-of-life patients in 10 countries using thematic analysis at three levels (i.e., locally in three countries, with codes shared in the three-country subgroup, and in all 10 countries with a codebook that we developed). We found that the patients' thoughts were oriented toward all three time levels (i.e., past, present, and future). Complementing these levels, we identified another, namely, the future after death. Each time level included patients actively and passively dealing with their thoughts. Past themes were remorse and regret, nostalgia, and coming to terms with past choices; present themes were feeling grateful for being alive, a time for farewells, and living for the day; future themes were worries about the future, to miss out, hope, ideas about death and dying, and planning the near future; and future after death themes were not being there, worries about loved ones, and preparations for a future after death. A changed view on lifetime and avoidance of thinking about a certain time level related to several time levels, while desire to die fluctuated between levels and between acting on and feeling about it. Living for the day, worries about the future, and worries about the well-being of loved ones were common themes in all countries.

RESUMEN

Adoptive transfer of tumor-infiltrating lymphocytes (TIL) has shown remarkable results in melanoma, but only modest clinical benefits in other cancers, even after TIL have been genetically modified to improve their tumor homing, cytotoxic potential or overcome cell exhaustion. The required ex vivo TIL expansion process may induce changes in the T cell clonal composition, which could likely compromise the tumor reactivity of TIL preparations and ultimately the success of TIL therapy. A promising approach based on the production of bispecific T cell-engagers (TCE) by engineered T cells (STAb-T therapy) improves the efficacy of current T cell redirection strategies against tumor-associated antigens in hematological tumors. We studied the TCRß repertoire in non-small cell lung cancer (NSCLC) tumors and in ex vivo expanded TIL from two unrelated patients. We generated TIL secreting anti-epidermal growth factor receptor (EGFR) × anti-CD3 TCE (TILSTAb) and tested their antitumor efficacy in vitro and in vivo using a NSCLC patient-derived xenograft (PDX) model in which tumor fragments and TIL from the same patient were transplanted into hIL-2 NOG mice. We confirmed that the standard TIL expansion protocol promotes the loss of tumor-dominant T cell clones and the overgrowth of virus-reactive TCR clonotypes that were marginally detectable in primary tumors. We demonstrated the antitumor activity of TILSTAb both in vitro and in vivo when administered intratumorally and systemically in an autologous immune-humanized PDX EGFR+ NSCLC mouse model, where tumor regression was mediated by TCE-redirected CD4+ TIL bearing non-tumor dominant clonotypes.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Glioblastoma (GB) is the most aggressive and prevalent glioma within the central nervous system. Despite considerable efforts, GB continues to exhibit a dismal 5-year survival rate (∼6%). This is largely attributed to unfavorable prognosis and lack of viable treatment options. Therefore, novel therapies centered around plant-derived compounds emerge as a compelling avenue to enhance patient survival and well-being. The South African species, Plectranthus hadiensis Schweinf. (P. hadiensis), a member of the Lamiaceae family, has a history of use in traditional medicine for treating a range of diseases, including respiratory, digestive, and liver disorders. This species exhibits diverse biological activities, such as anti-inflammatory and antitumoral properties, likely attributed to its rich composition of naturally occurring diterpenes, like the abietane diterpene, 7α-acetoxy-6ß-hydroxyroyleanone (Roy). Roy has demonstrated promising antitumor effects in various cancer cell lines, making it a compelling candidate for further investigation into its mechanisms against GB. AIM OF THE STUDY: This study aims to investigate the antitumor activity and potential mechanism of Roy, a natural lead compound, in GB cells. MATERIAL AND METHODS: Roy was isolated from the acetonic extract of P. hadiensis and its antitumor mechanism was assessed in a panel of human GB cell lines (U87, A172, H4, U373, and U118) to mimic tumor heterogeneity. Briefly, the impact of Roy treatment on the metabolic activity of cells was evaluated by Alamar Blue® assay, while cell death, cell cycle regulation, mitochondrial membrane potential, and activated caspase-3 activity were evaluated by flow cytometry. Measurement of mRNA levels of target genes was performed by qPCR, while protein expression was assessed by Western blotting. Cell uptake and impact on mitochondrial morphology were evaluated by confocal microscopy. RESULTS: Roy induced G2/M cell cycle arrest, mitochondrial fragmentation, and apoptosis by inhibiting the expression of anti-apoptotic proteins and increasing the levels of activated caspase-3. The concentrations of Roy needed to achieve significant inhibitory outcomes were notably lower (6-9 fold) than those of temozolomide (TMZ), the standard first-line treatment, for achieving comparable effects. In addition, at low concentrations (16 µM), Roy affected the metabolic activity of tumor cells while having no significant impact on non-tumoral cells (microglia and astrocytes). CONCLUSION: Overall, Roy demonstrated a robust antitumor activity against GB cells offering a promising avenue for the development of novel chemotherapeutic approaches.

RESUMEN

BACKGROUND: Mild cognitive impairment (MCI) involves cognitive decline beyond typical age-related changes, but without significant daily activity disruption. It can encompass various cognitive domains as the causes of MCI are diverse. MCI as well as frequent comorbid neuropsychiatric conditions like depression and anxiety affect individuals' quality of life. Early interventions are essential, and computerized cognitive training (cCT) is an established treatment method. This paper presents the protocol for the NeuroNation MED Effectiveness Study, evaluating the self-administered mobile cCT intervention ("NeuroNation MED") in individuals with MCI to assess training effects on cognitive domains, health competence, neuropsychiatric symptoms, psychological well-being, and the general application usability. METHODS: This study protocol presents a single-blinded multicenter randomized controlled trial that will be carried out in six study centers in Germany and Luxembourg. We included adults with MCI (existing F06.7 ICD-10-GM diagnosis and TICS ≥ 21 and ≤ 32). The intervention group will use a mobile, multi-domain cCT ("NeuroNation MED") for 12 weeks. Meanwhile, the wait list control group will receive standard medical care or no care. The eligibility of volunteers will be determined through a telephone screening. After completion of the baseline examination, patients will be randomly assigned to one of the experimental conditions in a 2:1 ratio. In total, 286 participants will be included in this study. The primary outcome is the change of cognitive performance measured by the index score of the screening module of the Neuropsychological Assessment Battery. Secondary outcomes are changes in the Cognitive Failures Questionnaire, Hospital Anxiety and Depression Scale, Health-49, Health Literacy Questionnaire, among others. All of the primary and secondary outcomes will be assessed at baseline and after the 12-week post-allocation period. Furthermore, the intervention group will undergo an assessment of the System Usability Scale, and the training data of the NeuroNation MED application will be analyzed. DISCUSSION: This study aims to assess the effectiveness of a mobile self-administered cCT in enhancing cognitive abilities among individuals diagnosed with MCI. Should the findings confirm the effectiveness of the NeuroNation MED app, it may confer possible benefits for the care management of patients with MCI, owing to the accessibility, cost-effectiveness, and home-based setting it provides. Specifically, the cCT program could provide patients with personalized cognitive training, educational resources, and relaxation techniques, enabling participants to independently engage in cognitive training sessions at home without further supervision.

RESUMEN

AbstractInfectious disease dynamics operate across biological scales: pathogens replicate within hosts but transmit among populations. Functional changes in the pathogen-host interaction thus generate cascading effects across organizational scales. We investigated within-host dynamics and among-host transmission of three strains (SAT-1, -2, -3) of foot-and-mouth disease viruses (FMDVs) in their wildlife host, African buffalo. We combined data on viral dynamics and host immune responses with mathematical models to ask the following questions: How do viral and immune dynamics vary among strains? Which viral and immune parameters determine viral fitness within hosts? And how do within-host dynamics relate to virus transmission? Our data reveal contrasting within-host dynamics among viral strains, with SAT-2 eliciting more rapid and effective immune responses than SAT-1 and SAT-3. Within-host viral fitness was overwhelmingly determined by variation among hosts in immune response activation rates but not by variation among individual hosts in viral growth rate. Our analyses investigating across-scale linkages indicate that viral replication rate in the host correlates with transmission rates among buffalo and that adaptive immune activation rate determines the infectious period. These parameters define the virus's relative basic reproductive number (ℛ0), suggesting that viral invasion potential may be predictable from within-host dynamics.

RESUMEN

Prostate cancer (PCa) is a complex and biologically diverse disease with no curative treatment options at present. This study aims to utilize computational methods to explore potential anti-PCa compounds based on differentially expressed genes (DEGs), with the goal of identifying novel therapeutic indications or repurposing existing drugs. The methods employed in this study include DEGs-to-drug prediction, pharmacokinetics prediction, target prediction, network analysis, and molecular docking. The findings revealed a total of 79 upregulated DEGs and 110 downregulated DEGs in PCa, which were used to identify drug compounds capable of reversing the dysregulated conditions (dexverapamil, emetine, parthenolide, dobutamine, terfenadine, pimozide, mefloquine, ellipticine, and trifluoperazine) at a threshold probability of 20% on several molecular targets, such as serotonin receptors 2a/2b/2c, HERG protein, adrenergic receptors alpha-1a/2a, dopamine D3 receptor, inducible nitric oxide synthase (iNOS), epidermal growth factor receptor erbB1 (EGFR), tyrosine-protein kinases, and C-C chemokine receptor type 5 (CCR5). Molecular docking analysis revealed that terfenadine binding to inducible nitric oxide synthase (-7.833 kcal.mol-1) and pimozide binding to HERG (-7.636 kcal.mol-1). Overall, binding energy ΔGbind (Total) at 0 ns was lower than that of 100 ns for both the Terfenadine-iNOS complex (-101.707 to -103.302 kcal.mol-1) and Ellipticine-TOPIIα complex (-42.229 to -58.780 kcal.mol-1). In conclusion, this study provides insight on molecular targets that could possibly contribute to the molecular mechanisms underlying PCa. Further preclinical and clinical studies are required to validate the therapeutic effectiveness of these identified drugs in PCa disease.

RESUMEN

PURPOSE: The present consensus statement was developed by the GINECOR working group on behalf of the Spanish Society of Radiation Oncology (SEOR). This document addresses sexual health management in patients with gynaecological cancer after pelvic radiotherapy. METHODS: A modified two-round online Delphi study was conducted, where GINECOR members were surveyed on the diagnosis, treatment, and follow-up of sexual health problems. An expert panel of radiation oncologists, nurses and a gynaecologist participated in the Delphi study to reach a consensus, applying GRADE criteria to establish the level of agreement. RESULTS: The consensus recommendations cover both diagnosis and treatment, with an emphasis on patient-reported outcome measures (PROMs). They highlight recommendations such as the systematic assessment of genitourinary, gastrointestinal, and sexual symptoms, and the use of several treatments after radiotherapy. Recommendations include pharmacological options like vaginal lubricants and hormone therapy, and mechanical interventions such as vaginal dilators and vibrators. These suggestions stem from both scientific evidence and clinical expertise. CONCLUSION: This consensus statement describes a comprehensive, multidisciplinary approach developed to address the sexual needs and enhance the quality of life of patients with gynaecological tumours after pelvic radiotherapy. It offers specific recommendations for managing sexual issues, emphasizing the importance of specialized care and regular assessment. The document underscores the significance of proactive, patient-centered sexual health management in gynaecological cancer patients.

RESUMEN

BACKGROUND: Sexual violence (SV) is a public health problem with high prevalence among the young population. The use of formal resources for SV care (e.g. institutional services) is low in this age group. This study applies a framework of health assets to identify the factors that positively influence the search for support for SV among young people, the functions of that support and the level of proximity as articulated by both young people and professionals. METHODS: A qualitative study was conducted through 38 semi-structured interviews with young people and professionals from SV resource centers and/or care services for the young population in Spain. A thematic theoretical analysis was conducted, embedded in inductive insights emerging from the data, following a particular adaptation of the constant comparative method, under the grounded theory approach. This analysis was carried out by coding the interview transcripts with the support of Atlas.ti. RESULTS: Young women identified assets, categorized as feminist, that they believe they are essential in the search for formal support services for SV. However, unlike young men, they considered the police and judicial system to be barriers and not assets. There were also differences between the young people and professionals in identifying assets. Young people also considered their partner and traditional media as health assets, in contrast to professionals who did not identify these as such valuable resources in the help-seeking process. Informal assets, such as family, friends and the internet are considered close resources. In contrast, specialized care services for gender-based violence/SV and the judicial and police systems were perceived as more distant resources among the young interviewees. CONCLUSIONS: This study shows similarities and discrepancies among young women and men and SV response professionals in identifying assets for seeking SV support among youth. The study shows an inverse relationship between perceptions of proximity and the level of formality of the asset. This study also contributes to map the relationships and information exchanges between assets. It is advisable to inform professionals about the assets that professionals do not acknowledge, and about actions that allow young people to access formal resources.

RESUMEN

BACKGROUND: Palliative care (PC) is oriented to improving the quality of life of patients and their families who are facing problems associated with life-threatening illness. It is a continuously changing and evolving field. Although it is a universal right, there are many barriers to addressing the unmet need for PC, affecting both patient and family as well as health care professionals (HCP). Many studies have highlighted the unmet needs of patients and caregivers, but it is also necessary to understand the needs of HCP in order to better develop PC. It is therefore necessary to identify all those barriers and unmet needs in order to develop and guarantee universal quality PC. METHODS: Bibliography search in relevant databases (PubMed, Cochrane Library, Trip Database) of documents published between 2018 and 2022, both included, written in English or Spanish. Key words-MeSH terms: Palliative Care, Palliative Medicine, Health Personnel, Continuing Education, Health Care Providers; and free text: healthcare professionals, continuous learning, training needs, gap, unmet needs, nursing. Articles about children or teenagers were excluded, as those related to the coronavirus disease 2019 (COVID-19) pandemic. RESULTS: A grand total of 1,150 documents were located and 20 were found through other sources. Additionally, 3 documents were found and kept despite not being included in the timeline previously discussed due to its relevance. Only 20 were finally included in this review. The identified unmet needs throughout the PC continuum have been categorized in three groups: diagnosis/recognition of the patient entering the PC continuum; end-of-life (EoL); and bereavement. Facilitators in PC have been identified in each category. CONCLUSIONS: Given the challenging nature of PC and the lack of knowledge throughout the continuum, addressing the challenges identified may result in meaningful and long-lasting results for both HCP and the patient-family unit. Training would be the answer to most of the unmet needs detected.

RESUMEN

For decades, multiple varieties of antibiotics have been successfully used for therapeutic purposes. Nevertheless, antibiotic resistance is currently one of the major threats to global health. This work presents an innovative laboratory practice carried out in an inorganic medicinal chemistry course within the Degrees of Pharmacy and Biochemistry for undergraduate students. This experiment includes three classes of 2 h each. The first class consisted of the mechanochemical synthesis of an antibiotic coordination framework (ACF) using a known antibiotic (nalidixic acid) and zinc as the ligand. The prepared Zn-nalidixic acid ACF (Zn-ACF) was obtained in up to 82% yield with high purity. On the second day, the synthesized Zn-ACF was characterized by Fourier-transform infrared spectroscopy (FTIR) and powder X-ray diffraction (PXRD). Finally, during the last class, the antimicrobial activity was tested against Escherichia coli by the well diffusion method. The students verified the higher antimicrobial activity of Zn-ACF compared to nalidixic acid, proving that small changes in the chemical structure can result in great biological differences. In the end, the students presented their results in a poster format, encouraging the development of their soft skills and scientific results communication and dissemination. In the future, it is expected that such a laboratory experiment at the interface between medicinal chemistry, microbiology, analytical techniques, public health, and pharmacology will lead to the development and implementation of some service-learning practices and will serve as a model to look at for other courses and institutions.

RESUMEN

BACKGROUND: The integral model of Palliative Care recognizes the community as essential element in improving quality of life of patients and families. It is necessary to find a formula that allows the community to have a voice. The aim of this scoping review is to identify barriers and facilitators to engage community in PC. METHODS: Systematic search was conducted in NICE, Cochrane Library, Health Evidence, CINAHL and PubMed database. KEYWORDS: Palliative care, End of life care, community networks, community engagement, public engagement, community participation, social participation, barriers and facilitators. RESULTS: Nine hundred seventy-one results were obtained. Search strategy and inclusion criteria yielded 13 studies that were read in detail to identify factors influencing community engagement in palliative care, categorized into: Public health and public engagement; Community attitudes towards palliative care, death and preferences at the end of life; Importance of volunteers in public engagement programs; Compassionate communities. CONCLUSION: Societal awareness must be a facilitated process to catalyse public engagement efforts. National policy initiatives and regional system support provide legitimacy and focus is essential for funding. The first step is to get a sense of what is important to society, bearing in mind cultural differences and to channel those aspects through health care professionals; connecting the most assistential part with community resources. The process and long-term results need to be systematically evaluated.

RESUMEN

BACKGROUND: The African continent is home to five biodiversity hotspots, boasting an immense wealth of medicinal flora, fungi and marine life. Diterpenes extracted from such natural products have compelling cytotoxic activities that warrant further exploration for the drug market, particularly in cancer therapy, where mortality rates remain elevated worldwide. PURPOSE: To demonstrate the potential of African natural products on the global stage for cancer therapy development and provide an in-depth analysis of the current literature on the activity of cancer cytotoxic diterpenes from African natural sources (to our knowledge, the first of its kind); not only to reveal the most promising candidates for clinical development, but to demonstrate the importance of preserving the threatened ecosystems of Africa. METHODS: A comprehensive search by means of the PRISMA strategy was conducted using electronic databases, namely Web of Science, PubMed, Google Scholar and ScienceDirect. The search terms employed were 'diterpene & mechanism & cancer' and 'diterpene & clinical & cancer'. The selection process involved assessing titles in English, Portuguese and Spanish, adhering to predefined eligibility criteria. The timeframe for inclusion spanned from 2010 to 2023, resulting in 218 relevant papers. Chemical structures were visualized using ChemDraw 21.0, PubChem was utilized to search for CID numbers. RESULTS: Despite being one of the richest biodiverse zones in the world, African natural products are proportionally underreported compared to Asian countries or otherwise. The diterpenes andrographolide (Andrographis paniculata), forskolin (Coleus forskohlii), ent-kauranes from Isodon spp., euphosorophane A (Euphorbia sororia), cafestol & kahweol (Coffea spp.), macrocylic jolkinol D derivatives (Euphorbia piscatoria) and cyathane erinacine A (Hericium erinaceus) illustrated the most encouraging data for further cancer therapy exploration and development. CONCLUSIONS: Diterpenes from African natural products have the potential to be economically significant active pharmaceutical and medicinal ingredients, specifically focussed on anticancer therapeutics.

RESUMEN

Glioblastoma (GB) is a devastating tumor of the central nervous system characterized by a poor prognosis. One of the best-established predictive biomarker in IDH-wildtype GB is O6-methylguanine-DNA methyltransferase (MGMT) methylation (mMGMT), which is associated with improved treatment response and survival. However, current efforts to monitor GB patients through mMGMT detection have proven unsuccessful. Small extracellular vesicles (sEVs) hold potential as a key element that could revolutionize clinical practice by offering new possibilities for liquid biopsy. This study aimed to determine the utility of sEV-based liquid biopsy as a predictive biomarker and disease monitoring tool in patients with IDH-wildtype GB. Our findings show consistent results with tissue-based analysis, achieving a remarkable sensitivity of 85.7% for detecting mMGMT in liquid biopsy, the highest reported to date. Moreover, we suggested that liquid biopsy assessment of sEV-DNA could be a powerful tool for monitoring disease progression in IDH-wildtype GB patients. This study highlights the critical significance of overcoming molecular underdetection, which can lead to missed treatment opportunities and misdiagnoses, possibly resulting in ineffective therapies. The outcomes of our research significantly contribute to the field of sEV-DNA-based liquid biopsy, providing valuable insights into tumor tissue heterogeneity and establishing it as a promising tool for detecting GB biomarkers. These results have substantial implications for advancing predictive and therapeutic approaches in the context of GB and warrant further exploration and validation in clinical settings.

RESUMEN

Spliced leader trans-splicing of pre-mRNAs is a critical step in the gene expression of many eukaryotes. How the spliced leader RNA and its target transcripts are brought together to form the trans-spliceosome remains an important unanswered question. Using immunoprecipitation followed by protein analysis via mass spectrometry and RIP-Seq, we show that the nematode-specific proteins, SNA-3 and SUT-1, form a complex with a set of enigmatic non-coding RNAs, the SmY RNAs. Our work redefines the SmY snRNP and shows for the first time that it is essential for nematode viability and is involved in spliced leader trans-splicing. SNA-3 and SUT-1 are associated with the 5' ends of most, if not all, nascent capped RNA polymerase II transcripts, and they also interact with components of the major nematode spliced leader (SL1) snRNP. We show that depletion of SNA-3 impairs the co-immunoprecipitation between one of the SL1 snRNP components, SNA-2, and several core spliceosomal proteins. We thus propose that the SmY snRNP recruits the SL1 snRNP to the 5' ends of nascent pre-mRNAs, an instrumental step in the assembly of the trans-spliceosome.

RESUMEN

INTRODUCTION: Intimate partner violence (IPV) is common among young people, but the use of IPV resources among young adult women and teenagers is limited. This study aims to analyze professionals' perceptions about the main barriers and facilitators encountered by young women (16-29 years old) exposed to intimate partner violence (IPV) when accessing formal services in Spain. METHODS: Qualitative study based on 17 in depth interviews carried out in 2019 with professionals who manage resources for IPV care in Madrid (Spain) from different sectors (social services, health care, security forces, women or youth issues offices, associations). A qualitative content analysis was conducted. RESULTS: The professionals interviewed perceive the following barriers: 1) Time it takes for young women to recognize IPV because the social construction of sexual-affective relationships is permeated by gender inequality; 2) The process of leaving a situation of abuse; 3) Barriers inherent to IPV services. The key aspects to improve access to these resources are related to care services, professional practice, and the young women themselves. CONCLUSIONS: There are both psychosocial barriers, derived from the process of leaving a situation of violence, as well as structural barriers for young women to access and properly use the recognized services specifically aimed at them or comprehensive IPV care. Services need to be tailored to the needs of young women so they can be truly effective in order to escape IPV.

RESUMEN

BACKGROUND: End-of-life (EoL) care volunteers in hospitals are a novel approach to support patients and their close ones. The iLIVE Volunteer Study supported hospital volunteer coordinators from five European countries to design and implement an EoL care volunteer service on general wards in their hospitals. This study aimed to identify and explore barriers and facilitators to the implementation of EoL care volunteer services in the five hospitals. METHODS: Volunteer coordinators (VCs) from the Netherlands (NL), Norway (NO), Slovenia (SI), Spain (ES) and United Kingdom (UK) participated in a focus group interview and subsequent in-depth one-to-one interviews. A theory-inspired framework based on the five domains of the Consolidated Framework for Implementation Research (CFIR) was used for data collection and analysis. Results from the focus group were depicted in radar charts per hospital. RESULTS: Barriers across all hospitals were the COVID-19 pandemic delaying the implementation process, and the lack of recognition of the added value of EoL care volunteers by hospital staff. Site-specific barriers were struggles with promoting the service in a highly structured setting with many stakeholders (NL), negative views among nurses on hospital volunteering (NL, NO), a lack of support from healthcare professionals and the management (SI, ES), and uncertainty about their role in implementation among VCs (ES). Site-specific facilitators were training of volunteers (NO, SI, NL), involving volunteers in promoting the service (NO), and education and awareness for healthcare professionals about the role and boundaries of volunteers (UK). CONCLUSION: Establishing a comprehensive EoL care volunteer service for patients in non-specialist palliative care wards involves multiple considerations including training, creating awareness and ensuring management support. Implementation requires involvement of stakeholders in a way that enables medical EoL care and volunteering to co-exist. Further research is needed to explore how trust and equal partnerships between volunteers and professional staff can be built and sustained. TRIAL REGISTRATION: NCT04678310. Registered 21/12/2020.

RESUMEN

The Plectranthus genus (Lamiaceae) is known to be rich in abietane diterpenes. The bioactive 6,7-dehydroxyroyleanone (DHR, 1) was previously isolated from Plectranthus madagascariensis var. madagascariensis and var. aliciae. This study aimed to explore the occurrence of DHR, 1, in P. aliciae and the potential bioactivities of new semisynthetic derivatives from DHR, 1. Several extraction methods were evaluated, and the hydrodistillation, using a Clevenger apparatus, afforded the highest yield (77.8 mg/g of 1 in the essential oil). Three new acyl derivatives (2-4) were successfully prepared from 1 (yields of 86-95%). Compounds 1-4 showed antioxidant activity, antibacterial effects, potent cytotoxic activity against several cell lines, and enhanced anti-inflammatory activity that surpassed dexamethasone (positive control). These findings encourage further exploration of derivatives 2-4 for potential mechanisms of antitumoral, antioxidant, and anti-inflammatory capabilities, studying both safety and efficacy.

RESUMEN

Many commensal gut microbes are recognized for their potential to synthesize vitamin B12, offering a promising avenue to address deficiencies through probiotic supplementation. While bioinformatics tools aid in predicting B12 biosynthetic potential, empirical validation remains crucial to confirm production, identify cobalamin vitamers, and establish biosynthetic yields. This study investigates vitamin B12 production in three human colonic bacterial species: Anaerobutyricum hallii DSM 3353, Roseburia faecis DSM 16840, and Anaerostipes caccae DSM 14662, along with Propionibacterium freudenreichii DSM 4902 as a positive control. These strains were selected for their potential use as probiotics, based on speculated B12 production from prior bioinformatic analyses. Cultures were grown in M2GSC, chemically defined media (CDM), and Gorse extract medium (GEM). The composition of GEM was similar to CDM, except that the carbon and nitrogen sources were replaced with the protein-depleted liquid waste obtained after subjecting Gorse to a leaf protein extraction process. B12 yields were quantified using liquid chromatography with tandem mass spectrometry. The results suggested that the three butyrate-producing strains could indeed produce B12, although the yields were notably low and were detected only in the cell lysates. Furthermore, B12 production was higher in GEM compared to M2GSC medium. The positive control, P. freudenreichii DSM 4902 produced B12 at concentrations ranging from 7 ng mL-1 to 12 ng mL-1. Univariate-scaled Principal Component Analysis (PCA) of data from previous publications investigating B12 production in P. freudenreichii revealed that B12 yields diminished when the carbon source concentration was ≤30 g L-1. In conclusion, the protein-depleted wastes from the leaf protein extraction process from Gorse can be valorised as a viable substrate for culturing B12-producing colonic gut microbes. Furthermore, this is the first report attesting to the ability of A. hallii, R. faecis, and A. caccae to produce B12. However, these microbes seem unsuitable for industrial applications owing to low B12 yields.
