From Substance to Skill: Student Perspective on Caring
Background: Nursing professionals unanimously agree that caring is the professional core, reflecting its uniqueness and distinguishing it from other health professions. The perception of caring seems to be changing with time along with nursing students' perceptions of this topic.Aim: This integrative review was aimed at presenting an overview of changes in student considerations when choosing the nursing profession and relating to the caring aspect.Methods: We reviewed past literature and defined “Caring”, “Nursing”, “Nursing Career”, “Patient Care” and “Students” as their keywords on Medline, PubMed, Embase and Web of Science. There was also conducted a manual search in order to find other potentially suitable resources.Results: The findings indicate that the concept of caring continues to be ambiguous and difficult to define, and demonstrate a different approach to caring as compared to the past.Conclusion: Caring is now considered more of a skill and less of a substance. The nursing education system should give their students a pack of tools that will develop an approach that consists of extensive practical knowledge alongside a strong understanding and empathy for the patient, in order to provide human and sensitive care

Dissertação de mestrado em Biotecnologia Farmacêutica, apresentada à Faculdade de Farmácia da Universidade de CoimbraEste trabalho abrange uma revisão do estado de arte do processo de liofilização e da sua aplicação na área da Nanotecnologia. O foco principal desta revisão é a caracterização dos produtos liofilizados inovadores existentes no mercado e em fase de desenvolvimento clínico, com aplicação em Oncologia.
Na área farmacêutica, a exploração das propriedades únicas das nanopartículas tornou-se diferenciadora pela demonstração de efeitos na biodisponibilidade de moléculas ativas e também na proteção contra a degradação enzimática. Mais recentemente, as nanopartículas têm sido usadas para proporcionar um aumento da especificidade e efetividade no direcionamento dos fármacos aos locais alvo, permitindo a diminuição da dose eficaz e da toxicidade geral. Com tudo isto, o desenvolvimento de nanoestruturas para transporte de fármacos tem sido objeto de um interesse crescente, tendo em vista colmatar alguns pontos negativos existentes nos sistemas de dosagem tradicionais.
No entanto, a estabilidade das nanopartículas pode constituir um problema, pelo que a sua concepção não é propriamente linear. No caso específico das nanodispersões coloidais, fatores físicos e químicos contribuem para uma baixa estabilidade a longo termo, provocando a destabilização do sistema que limita a sua aplicação clínica.
A liofilização surge neste cenário como um processo tecnológico que pode minimizar os problemas de estabilidade das suspensões aquosas de nanopartículas. Trata-se de uma técnica de desidratação muito eficiente quando comparada com as demais, que tem vindo a apresentar melhorias na estabilidade destas suspensões coloidais, e por esta razão merece destaque. Cada produto possui um ciclo de liofilização único em função das suas particularidades, o que faz com que este processo seja uma operação unitária. Para ser percetível a forma como o processo de liofilização é executado cumprindo as boas práticas laboratoriais (BPL/GLP) e de fabrico (BPF/GMP) são explícitos, neste estudo, os requisitos normativos a ter em conta.
A liofilização, além de ser útil ao nível da estabilidade, é ainda utilizada para outras finalidades que estão descritas no estudo. De forma a elucidar toda a operação envolvida neste processo é feita uma breve abordagem das etapas envolvidas, dos métodos utilizados, das
ix
aplicações farmacêuticas e dos principais pros e contras, com o intuito de entender a importância da formulação de nanopartículas liofilizadas.
Será ainda dedicado um capítulo ao estudo dos componentes e das condições do processo para conseguir obter resistência às tensões a que as suspensões de nanopartículas são submetidas durante a fase de congelamento na liofilização. Nesta fase, o efeito crioprotetor ou lioprotetor é determinante, dado que na reidratação do produto é mandatório que as propriedades originais das nanopartículas sejam mantidas.
A respeito dos avanços recentes com aplicação deste processo, são ainda apresentadas as formulações liofilizadas que estão inseridas no mercado e os ensaios clínicos e pré-clínicos existentes para o tratamento de doenças do foro oncológico, com referência aos produtos protegidos por patente.
A relevância deste trabalho traduz-se no facto de o resultado da pesquisa ser orientado em ambiente empresarial e académico, com vista à inserção no processo de valorização da propriedade intelectual de uma spin-off da Universidade de CoimbraThis work aims at conducting a review of the state of art of the lyophilization process and its application in the field of Nanotechnology. The main focus is the characterization of existing innovative freeze-dried products on the market and in clinical evaluation, with applications in Oncology.
In the pharmaceutical area, the unique properties of nanoparticles began to demonstrate positive effects on the bioavailability of active molecules and also in protecting against enzymatic degradation. More recently, nanoparticles have been used to provide increased specificity and effectiveness in the targeting of drugs to specific locations, thereby reducing the effective dose and toxicity. With all this, the development of nanostructures for drug delivery has provided the solution for existing weaknesses in traditional dosing systems.
However, the stability of the nanoparticles is not exactly a linear topic. In the case of colloidal nanodispersions, physical and chemical factors contribute to a low long term stability, leading to destabilization of the system and thus creating an obstacle to its clinical application.
Lyophilization in this scenario appears as a technological process that can minimize stability problems of aqueous suspensions of nanoparticles. It is a very efficient dewatering technique, which has been presenting improvements in the stability of these colloidal suspensions, and therefore noteworthy. Each product has a single lyophilization cycle on the basis of their features, which makes this process a unitary operation. To be noticeable how the freeze-drying process is performed in compliance with the good laboratory practice (BPL/GLP) and manufacturing practice (BPF/GMP), the regulatory requirements to be considered are explicit in this study.
This technique, besides being useful for stability issues, it is still used for other purposes which are described in the study. In order to elucidate the entire operation involved in this process, it is made a brief approach of the steps involved, the methods used, the pharmaceutical applications and the main pros and cons of the formulation of lyophilized nanoparticles.
The study also comprises a chapter on the components and process conditions to achieve resistance to the stresses to which the nanoparticulate suspensions are subjected during the
xi
freezing stage of the lyophilization. At this stage, the cryoprotectant or lioprotetor effect is decisive for the rehydration, in order to preserve that the original properties of the nanoparticles.
Regarding the recent advances in the application of this process, this study presents the most recent lyophilized formulations on the market and in clinical and preclinical trials for the treatment of oncological diseases, with reference to the proprietary products.
The main conclusions of this work will be included in the valuing process of the intellectual property of a spin-off from the University of Coimbra, combining an academic and business perspective on a pharmaceutical process of industrial application

Primary Care Physicians’ Perceptions on Nurses’ Shared Responsibility for Quality of Patient Care: A Survey
Nurses are key players in primary care in Israel and in the efforts to improve its quality, yet a survey conducted among primary care physicians (PCPs) in 2010 indicated that 40% perceived the contribution of nurses to primary care quality as moderate to very small. In 2020, we conducted a cross-sectional survey using self-report questionnaires among PCPs employed by health plans to examine the change in PCPs’ perceptions on nurses’ responsibility and contributions to quality of primary care between 2010 and 2020. Four-hundred-and-fifty respondents completed the questionnaire in 2020, as compared to 605 respondents in 2010. The proportion of PCPs who perceive that nurses share the responsibility for improving the quality of medical care increased from 74% in 2010 to 83% in 2020 (p < 0.01). Older age, males, self-employment status, and board certification in family medicine independently predicted reduced PCP perception regarding nurses’ responsibility for quality-of-care. PCPs who believed that nurses contribute to quality of practice were 7.2 times more likely to perceive that nurses share the responsibility for quality-of-care. The study showed that over the past decade there was an increase in the extent to which PCPs perceive nurses as significant partners in improving quality of primary care

Cost effectiveness of home care versus hospital care: a retrospective analysis
Abstract Background Increased utilization of health services due to population growth affects the allocation of national resources and budgets. Hence, it is important for national policy. Home hospitalization is one of the solutions for dealing with the growing demand for hospital beds and reducing the duration of hospitalization and its costs. It is gradually becoming part of the regular care in many health systems, yet, studies on the economic aspects of Community-Based Home Hospitalization (CBHH) implementation in Israel are few. The aim of this study is to examine costs of CBHH in comparison to costs of inpatient hospital care in the Israeli public health system. Methods Retrospective data was collected using document research in databases. A review of the costs of patients in CBHH at Maccabi Healthcare Services (MHS) was conducted. A total of 3374 patients were included in this study: 1687 patients who were in CBHH, and 1687 age- and sex-matched patients who were hospitalized in an internal department (the control group). The study population included the patients admitted to CBHH from January 2018 to July 2020, and patients admitted to internal medicine departments during the same period. Results The number of hospitalizations during the follow up period were statistically significantly lower in the CBHH group compared with the control group (M = 1.18, SD = 0.56 vs. M = 1.61, SD = 1.29, p < 0.001). In addition, the mean number of hospitalization days was also statistically significantly lower for 4.3 (SD = 4.5) for CBHH patients compared to the control group (M = 4.3 days, SD = 4.5 vs. M = 7.5 days, SD = 10.3, p < 0.001). Furthermore, the mean cost per day was statistically significantly higher for inpatient hospitalization compared to CBHH (M = 1829.1, SD = 87.5 vs. M = 783.2, SD = 178.3, p < 0.001). Older patients, patients with diabetes and patients hospitalized in hospitals had a higher number of hospitalization days. Conclusions The costs of CBHH seem to be lower than those of inpatient care. Managing CBHH is characterized by constantly measuring financial feasibility that would be an impetus for further development of this service
Addressing the second victim phenomenon in Israeli health care institutions
Abstract Background The ‘second victim’ phenomenon (SVP) refers to practitioners who experience a negative physical or emotional response, as well as a professional decline, after participating or witnessing an adverse event. Despite the Israeli Ministry of Health’s implementation of specific protocols regarding the overall management of adverse events in health organizations over the past decade, there is limited knowledge regarding healthcare managers’ perceptions of the ‘second victim’ occurrence. Methods A phenomenological qualitative approach was used to identify an accurate view of policy. Fifteen senior risk manager/and policy makers were interviewed about their knowledge and perceptions of the ‘second victim’. Topics addressed included reporting mechanisms of an adverse event, the degree of organizational awareness of ‘second victim’, and identifying components of possible intervention programs and challenges to implementing those programs. Results Examining current procedures reveals that there is limited knowledge about uniform guidance for health care organizations on how to identify, treat, or prevent SVP among providers. The employee support programs that were offered were sporadic in nature and depended on the initiative of a direct manager or the risk manager. Conclusions Currently, there is little information or organizational discussion about the possible negative effects of AE on healthcare practitioners. To provide overall medical care that is safe and effective for patients, the health system must also provide a suitable response to the needs of the medical provider. This could be achieved by establishing a national policy for all healthcare organizations to follow, raising awareness of the possible occurrence of SVP, and creating a standard for the subsequent identification, treatment and future prevention for providers who may be suffering
