RESUMO

Live-ins: A mapping of relevant actors and moral norms at the public health level Abstract: Background: Live-ins are embedded in a network of multiple actors that shape their current working and living situation. The causes and effects of live-in arrangements go far beyond the actual care relationship and include structures and stakeholders that are interconnected at the Public Health level. Besides a legal responsibility, these actors also have a moral responsibility, which the article focuses on. Aim: The article provides an overview of relevant actors and moral norms in the context of live-ins at the public health level. Methods: The method followed the "Context and Actor Analysis". Actors at the public health level that are relevant for the live-ins' situation were identified, and the responsibilities and tasks presented in their websites as well as their respective target groups were collected. The ethical dimension was extracted from these self-descriptions. Results: The 23 actors address the live-ins directly or indirectly in their various social roles. The self-given tasks and the moral norms deduced from them, for which the actors are particularly responsible, illustrate the importance of justice and respect. Conclusions: The work provides the basis for an urgently needed empirical-ethical analysis on the current state of responsibility-taking. Not only the variety of the live-ins' roles, but also the multitude of actors involved and shared norms illustrate the necessity of close cooperation to be able to fulfil their responsibility.

RESUMO

BACKGROUND: Both vulnerability and integrity represent action-guiding concepts in nursing practice. However, they are primarily discussed regarding patients-not nurses-and considered independently from rather than in relation to each other. AIM: The aim of this paper is to characterize the moral dimension of nurses' vulnerability and integrity, specify the concepts' relationship in nurses' clinical practice and, ultimately, allow a more fine-grained understanding. DESIGN: This discursive paper demonstrates how vulnerability and integrity relate to each other in nursing practice and carves out which types of vulnerability pose a threat to nurses' moral integrity. The concept of vulnerability developed by Mackenzie et al. (2014) is applied to the situation of nurses and expanded to include the concept of moral integrity according to Hardingham (2004). Four scenarios are used to demonstrate where and how nurses' vulnerabilities become particularly apparent in clinical practice. This leads to a cross-case discussion, in which the vulnerabilities identified are examined against the background of moral integrity and the relationship between the two concepts is determined in more detail. RESULTS AND CONCLUSION: Vulnerability and integrity do not only form a conceptual pair but also represent complementary moral concepts. Their joint consideration has both a theoretical and practical added value. It is shown that only specific forms of vulnerability pose a threat to moral integrity and the vulnerability-integrity relationship is mediated via moral distress. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The manuscript provides guidance on how the concrete threat(s) to integrity can be buffered and moral resilience can be promoted. Different types of threats also weigh differently and require specific approaches to assess and handle them at the micro-, meso- and macro-level of the healthcare system.

RESUMO

The glaring lack of formal and informal caregivers in Germany has not only become apparent in hospitals and nursing homes but also in home care arrangements. One tension is particularly pertinent in such arrangements: a 'family-oriented' logic of the long-term care insurance and the individual wishes of those in need of care meet the actual possibilities of family carers. This care gap has been compensated for by 24-hour care workers, so-called 'live-ins', from Eastern Europe for some years. This contribution maps the 'live-ins' situation comprehensively from an ethical perspective. Based on different constellations regarding the 'live-ins' status as a professional nurse or non-professional caregiver, which ethical principles and moral norms are affected by whom and potentially conflict with each other in such home care arrangements at a micro and meso level of care are outlined. Special attention is paid to the tension between self-care and care for others, and to questions of the shared responsibility in and social responsibility of those external services that are involved in home care in addition to the 'live-in'.In order to uncover, understand and influence the current ethical problems, an ethical framework that considers both the divergent interests of all individuals involved in the home care arrangement and their mutual dependency and vulnerability is needed.

RESUMO

Trust and trustworthiness are essential for good healthcare, especially in mental healthcare. New technologies, such as mobile health apps, can affect trust relationships. In mental health, some apps need the trust of their users for therapeutic efficacy and explicitly ask for it, for example, through an avatar. Suppose an artificial character in an app delivers healthcare. In that case, the following questions arise: Whom does the user direct their trust to? Whether and when can an avatar be considered trustworthy? Our study aims to analyze different dimensions of trustworthiness in the context of mobile health app use. We integrate O'Neill's account of autonomy, trust, and trustworthiness into a model of trustworthiness as a relational concept with four relata: B is trustworthy with respect to A regarding the performance of Z because of C. Together with O'Neill's criteria of trustworthiness (honesty, competence, and reliability), this four-sided model is used to analyze different dimensions of trustworthiness in an exemplary case of mobile health app use. Our example focuses on an app that uses an avatar and is intended to treat sleep difficulties. The conceptual analysis shows that interpreting trust and trustworthiness in health app use is multi-layered and involves a net of interwoven universal obligations. At the same time, O'Neill's approach to autonomy, trust, and trustworthiness offers a normative account to structure and analyze these complex relations of trust and trustworthiness using mobile health apps.

RESUMO

BACKGROUND: The use of Behavioural Insights (BI) is gaining increasing attention in the German health landscape. Abstract English-language models provide assistance in the application of BI. However, so far there is no model which (1) is specifically suitable for the health sector and (2) is based on the German language. In this context, the goal was to develop a comprehensive German-language BI model for the design of interventions that can change health behaviour. METHODS: The basis for the development were the two models MINDSPACE and EAST as well as the authors' own practical experiences. RESULTS: The developed AEIOU model consisted of five categories with a total of 20 instruments, the categories being (1) address (Ansprache), (2) simplicity (Einfachheit), (3) incentivisation (Incentivierung), (4) orientation (Orientierung), and (5) immediacy (Unmittelbarkeit). CONCLUSION: The AEIOU model forms the basis for the first German-language compilation of possible BI applications for the development of interventions in the health sector. The model has now to be tested in practice and examined for its usefulness.

RESUMO

BACKGROUND: Since the approval of the digital care law (Digitale-Versorgung-Gesetz-DVG) on 19.12.2019, physicians have been able to prescribe digital health applications (DHA). Patients are now entitled to such applications. The present article sets out to clarify how physicians should integrate DHAs into patient care and the ethical responsibilities they have in this process. METHODS: Based on an adapted principle-oriented case analysis, three hypothetical case scenarios are discussed. The argumentative-analytical approach is based on four established principles of medical ethics (following Beauchamp and Childress), namely autonomy, beneficence, non-maleficence and justice, as well as on the Model Professional Code of Conduct for Physicians working in Germany (MBO-Ä). RESULTS: When prescribing DHAs, physicians need to give patients additional information on the specific risks that result from such applications. Special attention must be paid to patients' digital health literacy. Furthermore, DHAs should not replace personal contact, but complement and support guideline-based treatment. To enable patients to use DHAs more independently, we recommend an 'app anamnesis'. CONCLUSION: Beauchamp's and Childress's principles as well as the MBO-Ä are instructive for handling DHAs in patient care. The Dos and Don'ts presented must be complemented by further guidance providing orientation for physicians on how to integrate DHAs in patient care in a responsible way.

RESUMO

BACKGROUND: The workplace has been identified as a priority setting for health promotion. There are potential advantages of systematically integrating Occupational Health Management (OHM) and Corporate Social Responsibility (CSR). However, OHM and CSR are usually overseen by different management branches with different sets of values, and there is a lack of empirical research regarding interfaces between OHM and CSR. Germany offers a particularly useful setting due to legislation requiring health to be promoted in the workplace. This study aims to examine key stakeholders' views and experiences regarding interfaces between OHM and CSR in German companies. METHODS: Individual semi-structured qualitative interviews were conducted with a sample of 77 German stakeholders from three different groups: experts in occupational health and corporate social responsibility from various companies (n = 35), business partners (n = 19), and various non-business partners (n = 23). Transcripts were analysed using qualitative content analysis. RESULTS: Participants identified several areas in which OHM and CSR are already interacting at strategic, structural and cultural levels, but also highlighted several barriers that undermine a more meaningful interaction. Participants reported difficulties in articulating the underlying ethical values relevant to both OHM and CSR at the strategic level. Several structural barriers were also highlighted, including a lack of resources (both financial and knowledge), and OHM and CSR departments not being fully developed or undertaken at entirely different operational levels. Finally, the missing practical implementation of corporate philosophy was identified as a critical cultural barrier to interfaces between OHM and CSR, with existing guidelines and companies' philosophies that already connect OHM and CSR not being embraced by employees and managers. CONCLUSIONS: There is already significant overlap in the focus of OHM and CSR, at the structural, strategic and cultural levels in many German companies. The potential is there, both in theory and practice, for the systematic combination of OHM and CSR. The insights from this study will be useful to ensure that closer integration between both management branches is set up in a socially sustainable and ethical manner.

RESUMO

BACKGROUND: Critical Incident Reporting Systems (CIRS) provide a well-proven method to identify clinical risks in hospitals. All professions can report critical incidents anonymously, low-threshold, and without sanctions. Reported cases are processed to preventive measures that improve patient and staff safety. Clinical ethics consultations offer support for ethical conflicts but are dependent on the interaction with staff and management to be effective. The aim of this study was to investigate the rationale of integrating an ethical focus into CIRS. METHODS: A six-step approach combined the analysis of CIRS databases, potential cases, literature on clinical and organizational ethics, cases from ethics consultations, and experts' experience to construct a framework for CIRS cases with ethical relevance and map the categories with principles of biomedical ethics. RESULTS: Four main categories of critical incidents with ethical relevance were derived: (1) patient-related communication; (2) consent, autonomy, and patient interest; (3) conflicting economic and medical interests; (4) staff communication and corporate culture. Each category was refined with different subcategories and mapped with case examples and exemplary related ethical principles to demonstrate ethical relevance. CONCLUSION: The developed framework for CIRS cases with its ethical dimensions demonstrates the relevance of integrating ethics into the concept of risk-, quality-, and organizational management. It may also support clinical ethics consultations' presence and effectiveness. The proposed enhancement could contribute to hospitals' ethical infrastructure and may increase ethical behavior, patient safety, and employee satisfaction.

RESUMO

BACKGROUND AND METHOD: People have a right to physical and mental integrity in all spheres of life. They also have the right to autonomous actions and informed decisions regarding their health. To ensure this, informed consent has been the ethico-legal gold standard in medicine for some years now. The registration for measures of behavioural prevention, in contrast, is mainly conducted through forms focussing on data protection, with little attention to full informed consent of future participants. In this article, we discuss the ethical challenges that arise when employees consent to health-promoting measures. We then examine whether the instrument of informed consent can be translated to the context of behavioural prevention. RESULTS: Informed consent can be transferred to the corporate context in an altered version. Of particular importance is not only the handling of health-related data, but also the appropriate disclosure of all essential information as well as voluntary participation. CONCLUSIONS: The adjusted version of informed consent in behavioural prevention ought to be developed further, resulting in a matrix of criteria that define conditions under which the informed consent can be applied to single measures of behavioural prevention.

RESUMO

The COVID-19 pandemic has both exposed and intensified various challenges for Public Health and the Public Health service (ÖGD) in Germany. However, it also offers a window of opportunity for effective long-term transformation of the country's Public Health system. Against this backdrop, an online survey was carried out among the members of the German Network of Young Professionals in Public Health (Nachwuchsnetzwerk Öffentliche Gesundheit (NÖG)) in October and November 2020. It sought to elicit members' experiences and views related to Public Health during the COVID-19 pandemic. The resulting preliminary "lessons learned" for the German Public Health context are presented in this article. Based on the results of the survey, recommendations were formulated which are intended to provide targeted and concrete advice for the strengthening and transformation of Public Health in Germany. The main issues that preoccupied the young professionals were the increased public and political attention to Public Health and the narrow focus on infectious disease control, the standing of Public Health in Germany and the strengths and weaknesses of Public Health structures and workforce. The recommendations are aimed at promoting long-term and holistic strengthening of Public Health, with the training of an interdisciplinary workforce of young professionals presenting a key focus.

RESUMO

DEFINITION OF THE PROBLEM: The COVID-19 pandemic poses a considerable challenge to the capacity and functionality of intensive care. This concerns not only resources but, above all, the physical and psychological boundaries of nursing professionals. The question of how care for others and self-care of nurses in intensive care units are related to each other in the context of the COVID-19 pandemic has not been addressed in public and scientific discourse so far. ARGUMENTS: The present contribution reflects this relationship with reference to the Code of Ethics of the International Council of Nurses, particularly considering principlism and the Care Ethics according to Joan Tronto. As a result, it shows a corridor of ethically justifiable care with several borders, above all: (1) self-care must not be given up completely for the benefit of care for others, and (2) a categorical subordination of care for others to self-care is ethically not justifiable. CONCLUSION: The article makes an important contribution to a differentiated ethical consideration of the rights and responsibilities of intensive care nurses as moral actors within the pandemic in Germany. It, thus, provides a first starting point for a broad social and political discourse which is urgently needed not only during but also after the pandemic in order to improve the situation of intensive care nurses and those who are cared for.

RESUMO

BACKGROUND: The COVID-19 pandemic poses particular challenges for people working in the medical sector. Some of the medical students and young medical professionals who are starting their work in healthcare facilities during this time are confronted with extraordinary moral challenges. A portion of them does not yet have sufficient coping skills to adequately deal with these challenges. This can lead to so-called moral distress (MoD). Permanent or intensive exposure to MoD can have serious consequences. Appropriate support services have the potential to improve the handling of MoD. OBJECTIVE: This article aims to provide an overview of the current state of research on MoD among medical students and young medical professionals in order to sensitize lecturers with responsibility for education and training and doctors in leading positions to the problem. MAIN PART: This article presents the scientific concept of MoD, known triggers, and options for prevention and intervention. The topic is presented with reference to the changes in patient care in the context of the COVID-19 pandemic and research needs are presented. CONCLUSION: The article illustrates the necessity of a German-language, interdisciplinary discourse on MoD among medical students and young professionals.

RESUMO

The Pasteurized Milk Ordinance (PMO) mandates milk hauling sanitation and operational practices; however, the use of vague language (i.e., "as needed") and gaps in processes lead to variability in industry practices. Our aim was to characterize industry milk hauling practices and identify areas that may be an unexplained source of contamination in the dairy processing continuum, and communicate this information with industry to cultivate best practices. The objectives of this study were to (1) survey industry hauling sanitation and operation practices in the Pacific Northwest region of the United States, and (2) quantify microbial populations [aerobic plate count (APC), lactic acid bacteria, coliforms] on the internal surfaces of transfer hoses (tanker and receiving bay) to determine their potential contribution to the microbiological quality of raw milk. Eleven facilities (78% response rate) participated in our survey. All facilities surveyed were compliant with the PMO; however, overall milk reception layout, sanitation practices, and routine maintenance greatly varied between facilities. Farm hose samples (n = 115) had significantly higher microbial loads (APC: mean 4.7 log cfu/100 cm2; median 5.1 log cfu/cm2) than receiving hose samples (n = 57; APC: mean: 2.1 log cfu/100 cm2; median 1.9 log cfu/100 cm2). Microbial populations on transfer hose surfaces did not correlate with time since last cleaning for either tanker or receiving bay hoses. Microbial content of farm hoses is likely to reflect the microbial quality of the previous milk transferred through the hose, making on-farm management practices the primary consideration to maintain low microbiological counts downstream. Upon arrival at the processor, 10% of farm hoses were missing caps. Although this did not correlate with elevated microbiological counts, uncapped farm hoses are exposed to the farm environment, provide opportunity for contamination, and are in violation of the PMO. Through observations made during our studies, manual cleaning procedures appear to be a major weakness in hauling practices and need more attention. Recognizing and communicating variability and areas of weakness allows industry to elevate their hauling sanitation and operational practices to maintain optimum milk microbiological quality.

RESUMO

The US Pasteurized Milk Ordinance (PMO) allows milk tanker trucks to be used repeatedly for 24 h before mandatory clean-in-place cleaning, but no specifications are given for the length of time a tanker can be empty between loads. We defined a worst-case hauling scenario as a hauling vessel left empty and dirty (idle) for extended periods between loads, especially in warm weather. Initial studies were conducted using 5-gallon milk cans (pilot-scale) as a proof-of-concept and to demonstrate that extended idle time intervals could contribute to compromised raw milk quality. Based on pilot-scale results, a commercial hauling study was conducted through partnership with a Pacific Northwest dairy co-op to verify that extended idle times of 6 h between loads have minimal influence on the microbiological populations and enzyme activity in subsequent loads of milk. Milk cans were used to haul raw milk (load 1), emptied, incubated at 30°C for 3, 6, 10, and 20 h, and refilled with commercially pasteurized whole milk (load 2) to measure cross-contamination. For the commercial-scale study, a single tanker was filled with milk from a farm known to have poorer quality milk (farm A, load 1), emptied, and refilled immediately (0 h) or after a delay (6 h) with milk from a farm known to have superior quality milk (farm B, load 2). In both experiments, milk samples were obtained from each farm's bulk tank and from the milk can or tanker before unloading. Each sample was microbiologically assessed for standard plate count (SPC), lactic acid bacteria (LAB), and coliform counts. Selected isolates were assessed for lipolytic and proteolytic activity using spirit blue agar and skim milk agar, respectively. The pilot-scale experiment effectively demonstrated that extended periods of idle (>3 h) of soiled hauling vessels can significantly affect the microbiological quality of raw milk in subsequent loads; however, extended idle times of 6 h or less would not measurably compromise milk quality in subsequent loads in commercial tankers. Current tanker sanitation practices appear to be sufficient for maintaining raw milk SPC, LAB, and coliform levels, which are important measures of milk quality.

RESUMO

Introduction: Cancer rates are rising in low- and middle-income countries. While point-of-care ultrasound is now available globally and could serve to mitigate against this rise, its use in diagnosing cancers is inconsistent in lower-resourced healthcare contexts. This proof-of-concept study investigates the feasibility of an ultrasound training concept in a low-resource setting. It evaluates whether this educational concept led to improved knowledge and application of ultrasound diagnostics, cancer screening and staging and patient care. Material and methods: The curriculum was developed through expert exchange and is based on the World Health Organisation's Manual of Diagnostic Ultrasound. It consisted of two didactic components: an on-site training phase across 5 days for a total of 24 hours, and a digital follow-up phase involving the meeting of a bi-weekly tumor board online. The learning objectives of the on-site training were normal imaging and recognition of common pathologies of the abdominal organs, vessels, lymph nodes, female breasts and lungs. The virtual tumour boards met to discuss cases and ultrasound findings, thus aiding continuing professional development after the training sessions had concluded. The face-to-face course component was accompanied by tests given before and after training as well as an evaluation sheet (Likert-scale with 1 = 'completely/very good' and 7 'not at all/very poor'). Results: Of 20 participants from a rural hospital in Tanzania, a total of 16 were included in the analysis (clinical officers n = 6; medical officers n = 10). A significant increase in knowledge (p < 0.01) was measured both in the subjective self-assessment and in the theoretical competence tests. In multivariate linear regression, the status 'medical officers yes' (ß = 5.4; p = 0.04) had a significant influence on theory test results at T2. During the 24 virtual tumour board meetings, 28 cases were discussed and a continuous improvement in image acquisition quality was observed. Conclusion: The ultrasound education concept comes with a sustainable increase in clinical competence and improved oncological ultrasound screening locally. There is potential for the transfer of the concept to other locations, which can be explored in the future.

RESUMO

Digital Mental Health Technologies (DMHTs) have the potential to close treatment gaps in settings where mental healthcare is scarce or even inaccessible. For this, DMHTs need to be affordable, evidence-based, justice-oriented, user-friendly, and embedded in a functioning digital infrastructure. This viewpoint discusses areas crucial for future developments of DMHTs. Drawing back on interdisciplinary scholarship, questions of health equity, consumer-, patient- and developer-oriented legislation, and requirements for successful implementation of technologies across the globe are discussed. Economic considerations and policy implications complement these aspects. We discuss the need for cultural adaptation specific to the context of use and point to several benefits as well as pitfalls of DMHTs for research and healthcare provision. Nonetheless, to circumvent technology-driven solutionism, the development and implementation of DMHTs require a holistic, multi-sectoral, and participatory approach.

RESUMO

BACKGROUND: Increasing evidence indicates a higher prevalence of polyneuropathy (PNP) in Parkinson's disease (PD). However, the involvement of large fiber neuropathy in PD still remains poorly understood. Given the lack of longitudinal data, we investigated the course of PNP associated with PD. METHODS: In total, 41 PD patients underwent comprehensive clinical evaluation including motor and non-motor assessments as well as nerve conduction studies at baseline and at 2 years of follow-up. The definition of PNP was based on electrophysiological standard criteria. Common causes of PNP were excluded. RESULTS: At baseline, PNP was diagnosed in 65.85% of PD patients via electroneurography. Patients with PNP presented with higher age (p = 0.019) and PD motor symptom severity (UPDRS III; p < 0.001). Over the course of 2 years, PNP deteriorated in 21.95% of cases, and 26.83% remained without PNP. Deterioration of nerve amplitude was most prevalent in the median sensory nerve affecting 57.58% of all PD cases with an overall reduction of median sensory nerve amplitude of 45.0%. With regard to PD phenotype, PNP progression was observed in 33.33% of the tremor dominant and 23.81% of the postural instability/gait difficulties subtype. Decrease of sural nerve amplitude correlated with lower quality of life (PDQ-39, p = 0.037) and worse cognitive status at baseline (MoCA, p = 0.042). CONCLUSION: The study confirms the high PNP rate in PD, and demonstrates a significant electrophysiological progression also involving nerves of the upper extremities. Longitudinal studies with larger cohorts are urgently needed and should elucidate the link between PD and PNP with the underlying pathomechanisms.

RESUMO

Interleukin-4 (IL-4) plays a key role in atopic diseases. It coordinates T-helper cell differentiation to subtype 2, thereby directing defense toward humoral immunity. Together with Interleukin-13, IL-4 further induces immunoglobulin class switch to IgE. Antibodies of this type activate mast cells and basophilic and eosinophilic granulocytes, which release pro-inflammatory mediators accounting for the typical symptoms of atopic diseases. IL-4 and IL-13 are thus major targets for pharmaceutical intervention strategies to treat atopic diseases. Besides neutralizing antibodies against IL-4, IL-13, or its receptors, IL-4 antagonists can present valuable alternatives. Pitrakinra, an Escherichia coli-derived IL-4 antagonist, has been evaluated in clinical trials for asthma treatment in the past; however, deficits such as short serum lifetime and potential immunogenicity among others stopped further development. To overcome such deficits, PEGylation of therapeutically important proteins has been used to increase the lifetime and proteolytic stability. As an alternative, glycoengineering is an emerging strategy used to improve pharmacokinetics of protein therapeutics. In this study, we have established different strategies to attach glycan moieties to defined positions in IL-4. Different chemical attachment strategies employing thiol chemistry were used to attach a glucose molecule at amino acid position 121, thereby converting IL-4 into a highly effective antagonist. To enhance the proteolytic stability of this IL-4 antagonist, additional glycan structures were introduced by glycoengineering utilizing eucaryotic expression. IL-4 antagonists with a combination of chemical and biosynthetic glycoengineering could be useful as therapeutic alternatives to IL-4 neutralizing antibodies already used to treat atopic diseases.
