    Benign prostatic hyperplasia (BPH) is one of the most common urinary diseases affecting men, generally after the age of 50. The prevalence of this multifactorial disease increases with age. With aging, the plasma level of testosterone decreases, as well as the testosterone/estrogen ratio, resulting in increased estrogen activity, which may facilitate the hyperplasia of the prostate cells. Another theory focuses on dihydrotestosterone (DHT) and the activity of the enzyme 5α-reductase, which converts testosterone to DHT. In older men, the activity of this enzyme increases, leading to a decreased testosterone/DHT ratio. DHT may promote prostate cell growth, resulting in hyperplasia. Some medicinal plants and their compounds act by modulating this enzyme, and have the above-mentioned targets. This review focuses on herbal drugs that are most widely used in the treatment of BPH, including pumpkin seed, willow herb, tomato, maritime pine bark, Pygeum africanum bark, rye pollen, saw palmetto fruit, and nettle root, highlighting the latest results of preclinical and clinical studies, as well as safety issues. In addition, the pharmaceutical care and other therapeutic options of BPH, including pharmacotherapy and surgical options, are discussed, summarizing and comparing the advantages and disadvantages of each therapy

    Ethical and research governance approval across Europe:Experiences from three European palliative care studies

    Get PDF
    Background: Research requires high-quality ethical and governance scrutiny and approval. However, when research is conducted across different countries, this can cause challenges due to the differing ethico-legal framework requirements of ethical boards. There is no specific guidance for research which does not involve non-medicinal products. Aim: To describe and address differences in ethical and research governance procedures applied by research ethics committees for non-pharmaceutical palliative care studies including adult participants in collaborative European studies. Design: An online survey analysed using descriptive statistics. Setting/participants: Eighteen principal investigators in 11 countries conducting one of three European-funded studies. Results: There was variation in practice including whether ethical approval was required. The time to gain full approvals differed with the United Kingdom having governance procedures that took the longest time. Written consent was not required in all countries nor were data safety monitoring committees for trials. There were additional differences in relation to other data management issues. Conclusion: Researchers need to take the differences in research approval procedures into account when planning studies. Future research is needed to establish European-wide recommendations for policy and practice that dovetail ethical procedures and enhance transnational research collaborations

    Implementation of palliative care consult Service in Hungary

    Get PDF
    __Background:__ The Palliative Care Consult Service (PCCS) programme was among the first initiations in Hungary to provide palliative care for patients admitted to hospital. The PCCS team provides palliative care for mainly cancer patients and their family members and manages the patient pathway after being discharged from the hospital. The service started in 2014 with 300-400 patient visits per year. The aim of this study is to give a comprehensive overview of the PCCS programme guided by a conceptual framework designed by SELFIE ("Sustainable intEgrated chronic care modeLs for multi-morbidity: delivery, FInancing, and performancE"), a Horizon2020 funded EU project and to identify the facilitators and barriers to its wider implementation. __Methods:__ PCCS has been selected by the SELFIE consortium for in-depth evaluation as one of the Hungarian integrated care models for persons with multi-morbidity. The qualitative analysis of the PCCS programme was based on available documents of the care provider and interviews with different stakeholders related to the programme. __Results:__ The integrated, multidisciplinary and patient-centred approach was well-received among the patients, family members and clinical departments, as verified by the increasing number of requests for consultations. As a result of the patient pathway management across providers (e.g. from inpatient care to homecare) a higher level of coordination could be achieved in the continuity of care for seriously-ill patients. The regulatory framework has only partially been established, policies to integrate care across organizations and sectors and adequate financial mechanism to support the enhancement and sustainability of the PCCS are still missing. __Conclusions:__ The service integration of palliative car

    Funding models in palliative care: lessons from international experience

    Background:Funding models influence provision and development of palliative care services. As palliative care integrates into mainstream health care provision, opportunities to develop funding mechanisms arise. However, little has been reported on what funding models exist or how we can learn from them.Aim:To assess national models and methods for financing and reimbursing palliative care.Design:Initial literature scoping yielded limited evidence on the subject as national policy documents are difficult to identify, access and interpret. We undertook expert consultations to appraise national models of palliative care financing in England, Germany, Hungary, Republic of Ireland, New Zealand, The Netherlands, Norway, Poland, Spain, Sweden, Switzerland, the United States and Wales. These represent different levels of service development and a variety of funding mechanisms.Results:Funding mechanisms reflect country-specific context and local variations in care provision. Patterns emerging include the following:Provider payment is rarely linked to population need and often perpetuates existing inequitable patterns in service provision.Funding is frequently characterised as a mixed system of charitable, public and private payers.The basis on which providers are paid for services rarely reflects individual care input or patient needs.Conclusion:Funding mechanisms need to be well understood and used with caution to ensure best practice and minimise perverse incentives. Before we can conduct cross-national comparisons of costs and impact of palliative care, we need to understand the funding and policy context for palliative care in each country of interest

    Degenerated cones in cultured human retinas can successfully be optogenetically reactivated

    Biblical references aside, restoring vision to the blind has proven to be a major technical challenge. In recent years, considerable advances have been made towards this end, especially when retinal degeneration underlies the vision loss such as occurs with retinitis pigmentosa. Under these conditions, optogenetic therapies are a particularly promising line of inquiry where remaining retinal cells are made into "artificial photoreceptors". However, this strategy is not without its challenges and a model system using human retinal explants would aid its continued development and refinement. Here, we cultured post-mortem human retinas and show that explants remain viable for around 7 days. Within this period, the cones lose their outer segments and thus their light sensitivity but remain electrophysiologically intact, displaying all the major ionic conductances one would expect for a vertebrate cone. We optogenetically restored light responses to these quiescent cones using a lentivirus vector constructed to express enhanced halorhodopsin under the control of the human arrestin promotor. In these 'reactivated' retinas, we show a light-induced horizontal cell to cone feedback signal in cones, indicating that transduced cones were able to transmit their light response across the synapse to horizontal cells, which generated a large enough response to send a signal back to the cones. Furthermore, we show ganglion cell light responses, suggesting the cultured explant's condition is still good enough to support transmission of the transduced cone signal over the intermediate retinal layers to the final retinal output level. Together, these results show that cultured human retinas are an appropriate model system to test optogenetic vision restoration approaches and that cones which have lost their outer segment, a condition occurring during the early stages of retinitis pigmentosa, are appropriate targets for optogenetic vision restoration therapies.Therapeutic cell differentiatio

    Review of European guidelines on palliative sedation: a foundation for the updating of the European Association for Palliative Care framework

    Get PDF
    in 2009, the European Association for Palliative Care (EAPC) developed a framework on palliative sedation, acknowledging this practice as an important and ethically acceptable intervention of last resort for terminally ill patients experiencing refractory symptoms. Before and after that, other guidelines on palliative sedation have been developed in Europe with variations in terminology and concepts. As part of the Palliative Sedation project (Horizon 2020 Funding No. 825700), a revision of the EAPC framework is planned. The aim of this article is to analyze the most frequently used palliative sedation guidelines as reported by experts from eight European countries to inform the discussion of the new framework. The three most reported documents per country were identified through an online survey among 124 clinical experts in December 2019. Those meeting guideline criteria were selected. Their content was assessed against the EAPC framework on palliative sedation. The quality of their methodology was evaluated with the Appraisal Guideline Research and Evaluation (AGREE) II instrument. Nine guidelines were included. All recognize palliative sedation as a last-resort treatment for refractory symptoms, but the criterion of refractoriness remains a matter of debate. Most guidelines recognize psychological or existential distress as (part of) an indication and some make specific recommendations for such cases. All agree that the assessment should be multiprofessional, but they diverge on the expertise required by the attending physician/team. Regarding decisions on hydration and nutrition, it is proposed that these should be independent of those for palliative sedation, but there is no clear consensus on the decision-making process. Several weaknesses were highlighted, particularly in areas of rigor of development and applicability. The identified points of debate and methodological weaknesses should be considered in any update or revision of the guidelines analyzed to improve the quality of their content and the applicability of their recommendations

    Potential function for the Huntingtin protein as a scaffold for selective autophagy

    Although dominant gain-of-function triplet repeat expansions in the Huntingtin (HTT) gene are the underlying cause of Huntington disease (HD), understanding the normal functions of nonmutant HTT protein has remained a challenge. We report here findings that suggest that HTT plays a significant role in selective autophagy. Loss of HTT function in Drosophila disrupts starvation-induced autophagy in larvae and conditional knockout of HTT in the mouse CNS causes characteristic cellular hallmarks of disrupted autophagy, including an accumulation of striatal p62/SQSTM1 over time. We observe that specific domains of HTT have structural similarities to yeast Atg proteins that function in selective autophagy, and in particular that the C-terminal domain of HTT shares structural similarity to yeast Atg11, an autophagic scaffold protein. To explore possible functional similarity between HTT and Atg11, we investigated whether the C-terminal domain of HTT interacts with mammalian counterparts of yeast Atg11-interacting proteins. Strikingly, this domain of HTT coimmunoprecipitates with several key Atg11 interactors, including the Atg1/Unc-51–like autophagy activating kinase 1 kinase complex, autophagic receptor proteins, and mammalian Atg8 homologs. Mutation of a phylogenetically conserved WXXL domain in a C-terminal HTT fragment reduces coprecipitation with mammalian Atg8 homolog GABARAPL1, suggesting a direct interaction. Collectively, these data support a possible central role for HTT as an Atg11-like scaffold protein. These findings have relevance to both mechanisms of disease pathogenesis and to therapeutic intervention strategies that reduce levels of both mutant and normal HTT.Hereditary Disease Foundation (U.S.)Cure Huntington’s Disease Initiative, Inc.Fox Family Foundatio

    Integrated palliative care in Europe: a qualitative systematic literature review of empirically-tested models in cancer and chronic disease

    Get PDF
    Integrated Palliative Care (PC) strategies are often implemented following models, namely standardized designs that provide frameworks for the organization of care for people with a progressive life-threatening illness and/or for their (in)formal caregivers. The aim of this qualitative systematic review is to identify empirically-evaluated models of PC in cancer and chronic disease in Europe. Further, develop a generic framework that will consist of the basis for the design of future models for integrated PC in Europe. Methods: Cochrane, PubMed, EMBASE, CINAHL, AMED, BNI, Web of Science, NHS Evidence. Five journals and references from included studies were hand-searched. Two reviewers screened the search results. Studies with adult patients with advanced cancer/chronic disease from 1995 to 2013 in Europe, in English, French, German, Dutch, Hungarian or Spanish were included. A narrative synthesis was used. Results: 14 studies were included, 7 models for chronic disease, 4 for integrated care in oncology, 2 for both cancer and chronic disease and 2 for end-of-life pathways. The results show a strong agreement on the benefits of the involvement of a PC multidisciplinary team: better symptom control, less caregiver burden, improvement in continuity and coordination of care, fewer admissions, cost effectiveness and patients dying in their preferred place. Conclusion: Based on our findings, a generic framework for integrated PC in cancer and chronic disease is proposed. This framework fosters integration of PC in the disease trajectory concurrently with treatment and identifies the importance of employing a PC-trained multidisciplinary team with a threefold focus: treatment, consulting and training

    Towards integration of palliative care in patients with chronic heart failure and chronic obstructive pulmonary disease:a systematic literature review of European guidelines and pathways

    Despite the positive impact of Palliative Care (PC) on the quality of life for patients and their relatives, the implementation of PC in non-cancer health-care delivery in the EU seems scarcely addressed. The aim of this study is to assess guidelines/pathways for integrated PC in patients with advanced Chronic Heart Failure (CHF) and Chronic Obstructive Pulmonary Disease (COPD) in Europe via a systematic literature review. Methods Search results were screened by two reviewers. Eligible studies of adult patients with CHF or COPD published between 01/01/1995 and 31/12/2013 in Europe in 6 languages were included. Nine electronic databases were searched, 6 journals were hand-searched and citation tracking was also performed. For the analysis, a narrative synthesis was employed. Results The search strategy revealed 26,256 studies without duplicates. From these, 19 studies were included in the review; 17 guidelines and 2 pathways. 18 out of 19 focused on suffering reduction interventions, 13/19 on a holistic approach and 15/19 on discussions of illness prognosis and limitations. The involvement of a PC team was mentioned in 13/19 studies, the assessment of the patients’ goals of care in 12/19 and the advance care planning in 11/19. Only 4/19 studies elaborated on aspects such as grief and bereavement care, 7/19 on treatment in the last hours of life and 8/19 on the continuation of goal adjustment. Conclusion The results illustrate that there is a growing awareness for the importance of integrated PC in patients with advanced CHF or COPD. At the same time, however, they signal the need for the development of standardized strategies so that existing barriers are alleviated
