Differences of mentally ill patients' satisfaction degree during their involuntary or voluntary stay in a psychiatric clinic.

BACKGROUND: Mental health illness is not considered as a private matter, as it affects not only the mental patient's life and those who are considered his/her immediate family, but also the society as a whole. The involuntary examination and/or hospitalization in the field of mental health as the basic first-line therapeutic solution in Greece, calls for an immediate intervention, which is supposed to counterbalance the need for therapy and patient's rights of personal freedom and safety. DESIGN AND METHODS: A research using questionnaire was realized, consisting of 100 hospitalized patients in psychiatric clinics (50 voluntarily and 50 involuntarily hospitalized) at the Psychiatric Hospital of Attica. The sampling scheme was the stratified sampling and the level of statistical significance was set to α=0.05. RESULTS: The results have shown that involuntarily and voluntarily hospitalized mental patients did not differ significantly with almost the entirety of the questionnaire; however, the involuntary patients were significantly more satisfied with the conditions of hospitalization as well as assessing the overall quality of the services provided during their hospitalization. CONCLUSIONS: For mentally ill patients, greater importance and stronger correlation with gratification, does not constitute the admission procedure to the psychiatric clinic but the development of effective communication and therapeutic relationship with the staff, full knowledge and update about patient's health condition, medication, participation in therapeutic planning and hospitalization in a regime of autonomy and respect for their rights.

Learning Organizational Culture in Greek Public Hospitals.

(1) Background: A learning organizational culture is crucial to the safety of patients and the quality of public health care. The aim of this study was to assess the learning organizational culture and capacity of Greek public hospitals. (2) Materials and Methods: A cross-sectional analysis was carried out in six public general hospitals and stratified sampling was used as the sampling technique. A total of 480 questionnaires were distributed to health care professionals and 380 valid questionnaires were returned (78% response rate). The comprehensive form of the Dimensions of Learning Organization Questionnaire (DLOQ), which was adapted and translated into Greek, was used for data collection in this survey. (3) Results: The level of learning organizational culture and capacity in the health units are very low. All seven dimensions of the learning organizational instrument are lower than the theoretically neutral median (3.0). Health care employees believe that the hospital's existing culture and management practices do not foster and contribute to continuing learning, which is the fundamental aspect of self-development, department development and performance improvement. (4) Conclusions: Greek public hospitals need to adopt different types of leadership practices and culture in order to be able to facilitate organizational learning. Organizational learning (OL) is based on collaborative working, a culture that encompasses learning as participation in the organizational work practice. This transformation of culture should take place at all levels of learning to enhance results.

Selection Criteria of Cord Blood Units for Platelet Gel Production: Proposed Directions from Hellenic Cord Blood Bank. Comment on Mallis et al. Short Term Results of Fibrin Gel Obtained from Cord Blood Units: A Preliminary in Vitro Study. Bioengineering 2019, 6, 66.

This article provides additional knowledge for cord blood platelet gel (CBPG) production. Recently, it has been shown that CBPG exerts beneficial properties in wound healing applications. CBPG is produced after a two-step centrifugation process, following the addition of calcium gluconate. Clinical-grade CBPG can be produced in public cord blood banks, worldwide. However, standardization of the CBPG production process must be established in order to reduce discrepancies that occurred due to different platelet gel preparations. This article aims to provide an update regarding the selection criteria of cord blood units (CBUs), and to provide evidence for the improvement of the CBPG production process.

Validation of Dimensions of Learning Organization Questionnaire (DLOQ) in health care setting in Greece.

Background: In health care systems the organizational learning is a continuous process to improve actions through better knowledge and detect or correct errors. This study examines the validity and reliability of the Dimensions of Learning Organization Questionnaire in addition to the applicability of the instrument in a Greek health care cultural context. Design and methods: A cross-sectional study was carried out in 6 general hospitals of Attica and the sampling scheme was the stratified sampling. Questionnaires were distributed to 487 healthcare professionals and 380 valid questionnaires were returned. The research tool used in this survey is the extensive form of DLOQ, which has been adapted and translated into Greek language. Data analysis was carried out with SPSS 25. Results: Three leading experts of the health sector examined the face validity assessment of the translated DLOQ and stated that it is characterized by high face validity. As regard construct validity of the DOLQ throughout Multitrait-Multimethod Matrix, was proved that all the variables of the same factors are statistically significantly correlated (p<0.001), and their correlation coefficients have moderate to high power ranging between 0.563 and 0.798. Moreover, the discriminant validity was demonstrated as certain correlation coefficients between variables of different factors were found to be higher than of certain correlation coefficients between variables of the same factors. The internal consistency among the items of the DOLQ range between 0.842 and 0.977 and they are considered to be good to excellent. Conclusions: Our results confirmed that DLOQ is a valuable tool in measuring Learning Organizational in Greek public hospitals.

Advanced Therapy Medicinal Products Challenges and Perspectives in Regenerative Medicine.

Recently, the design and development of a modern health policy in the field of regenerative medicine leads to the formation of a new and integrated cognitive field, which requires systematic research and study in order to produce innovative answers and best practices. Advanced therapy medicinal products (ATMPs) is a new product category, which is at the heart of concern since it has to deal with diseases in which traditional medicine has proven to be ineffective so far. The aim of this review is to provide evidence for the state of the art ATMPs and their modern applications in the field of regenerative medicine. The ATMPs are characterized by a great heterogeneity and variation in methods of isolation, which cover the entire spectrum from a single intravenous injection to a surgical placement. Clinical development of ATMP encounters specific challenges due to the nature of the product and the limited availability of non-clinical data. The gold standard of a controlled, randomized, clinical trial may not be feasible or ethically justified for all indications, particularly in life-threatening diseases, where there is no satisfactory standard of care. Therefore, the European Commission (EC) took initiatives in order to set standards and operating rules concerning authorization and supervision of ATMPs and on pharmacovigilance in relation to them. The European Union (EU) Regulation 1394/2007 provides the possibility of exceptions. In particular, the "hospital exemption" allows for the administration of an ATMP without a license on certain conditions. Although the Regulation 1394/2007 has led to the commercial exploitation of ATMPs, the reality today, 11 years after its first implementation, is completely different. While the Committee for Advanced Therapies (CAT) has already registered 285 products as ATMPs, only 10 licenses were granted which only remained six (the rest related to products withdrawn). The key players in the development and delivery of ATMPs still remain the academic/research centers and small and medium-sized enterprises; while the involvement of pharmaceutical companies is focusing on recent developments in the treatment of oncological incidents with in vitro modified cytotoxic T lymphocytes, and chimeric antigen receptor (CAR)-T cells.

Myelin-associated glycoprotein inhibits neurite outgrowth through inactivation of the small GTPase Rap1.

Rap1 is a small GTPase that has been implicated in dendritic development and plasticity. In this study, we investigated the role of Rap1 in axonal growth and its activation in response to neurotrophins and myelin-associated inhibitors. We report that Rap1 is activated by brain-derived neurotrophic factor and that this activation can be blocked by myelin-associated glycoprotein (MAG) or central nervous system myelin, which also induced increases in Rap1GAP1 levels. In addition, we demonstrate that adenoviral overexpression of Rap1 enhances neurite outgrowth in the presence of MAG and myelin, while inhibition of Rap1 activity through overexpression of Rap1GAP1 blocks neurite outgrowth. These findings suggest that Rap1GAP1 negatively regulates neurite outgrowth, making it a potential therapeutic target to promote axonal regeneration.

Short Term Results of Fibrin Gel Obtained from Cord Blood Units: A Preliminary in Vitro Study.

BACKGROUND: Recent findings have shown that the fibrin gel derived from cord blood units (CBUs) play a significant role in wound healing and tissue regeneration. The aim of this study was to standardize the fibrin gel production process in order to allow for its regular use. METHODS: CBUs (n = 200) were assigned to 4 groups according to their initial volume. Then, a two-stage centrifugation protocol was applied in order to obtain platelet rich plasma (PRP). The concentration of platelets (PLTs), white blood cells (WBCs) and red blood cells (RBCs) were determined prior to and after the production process. In addition, targeted proteomic analysis using multiple reaction monitoring was performed. Finally, an appropriate volume of calcium gluconate was used in PRP for the production of fibrin gel. RESULTS: The results of this study showed that high volume CBUs were characterized by greater recovery rates, concentration and number of PLTs compared to the low volume CBUs. Proteomic analysis revealed the presence of key proteins for regenerative medicine. Fibrin gel was successfully produced from CBUs of all groups. CONCLUSION: In this study, low volume CBUs could be an alternative source for the production of fibrin gel, which can be used in multiple regenerative medicine approaches.

Biovigilance for the Quality and Safety of Medical Products of Human Origin.

Progress in science and technology in the health services has led to the development of methods of regenerating and replacing solid organs, tissues and cells, using human body components to create medical products of human origin intended for clinical use. In the activities in which products of human origin are used, however, from the point of donation and harvesting to the subsequent care of the recipient, medical products of human origin are exposed to the risk of specific complications related to the transmission of infectious diseases, and further side-effects. Biovigilance system application is a basic requirement for ensuring the quality and safety of tissues and cells intended for human use. The quality system focuses on error prevention, maintaining a consistent pattern of agreed assays for tissues and cells intended for clinical use. The implementation of quality and safety standards, the development of medical protocols and cooperation protocols between member states, the implementation of Single European Code (SEC), and the development of electronic traceability systems, all aim at vigilance and the surveillance of medical products of human origin from donation to transplantation.
