Clinically Important Benefits and Harms of Monoclonal Antibodies Targeting Amyloid for the Treatment of Alzheimer Disease: A Systematic Review and Meta-Analysis.

PURPOSE: We conducted a meta-analysis to evaluate clinically meaningful benefits and harms of monoclonal antibodies targeting amyloid in patients with Alzheimer dementia. METHODS: We searched PubMed, Cochrane CENTRAL, and 5 trial registries, as well as the reference lists of identified studies. We included randomized controlled trials comparing a monoclonal antibody with placebo at a dose consistent with that used in phase 3 trials or for Food and Drug Administration approval. Studies had to report at least 1 clinically relevant benefit or harm. Data were extracted independently by at least 2 researchers for random effects meta-analysis. Changes in cognitive and functional scales were compared between groups, and each difference was assessed to determine if it met the minimal clinically important difference (MCID). RESULTS: We identified 19 publications with 23,202 total participants that evaluated 8 anti-amyloid antibodies. There were small improvements over placebo in the Alzheimer's Disease Assessment Scale (ADAS)-Cog-11 to -14 score (standardized mean difference = -0.07; 95% CI, -0.10 to -0.04), Mini Mental State Examination score (0.32 points; 95% CI, 0.13 to 0.50), and Clinical Dementia Rating-Sum of Boxes scale score (mean difference =-0.18 points; 95% CI, -0.34 to -0.03), and the combined functional scores (standardized mean difference = 0.09; 95% CI, 0.05 to 0.13). None of the changes, including those for lecanemab, aducanumab, and donanemab, exceeded the MCID. Harms included significantly increased risks of amyloid-related imaging abnormalities (ARIA)-edema (relative risk [RR] = 10.29; number needed to harm [NNH] = 9), ARIA-hemorrhage (RR = 1.74; NNH = 13), and symptomatic ARIA-edema (RR = 24.3; NNH = 86). CONCLUSIONS: Although monoclonal antibodies targeting amyloid provide small benefits on cognitive and functional scales in patients with Alzheimer dementia, these improvements are far below the MCID for each outcome and are accompanied by clinically meaningful harms.

A Participant-Centered Approach to Understanding Risks and Benefits of Participation in Research Informed by the Kidney Precision Medicine Project.

An understanding of the ethical underpinnings of human subjects research that involves some risk to participants without anticipated direct clinical benefit-such as the kidney biopsy procedure as part of the Kidney Precision Medicine Project (KPMP)-requires a critical examination of the risks as well as the diverse set of countervailing potential benefits to participants. This kind of deliberation has been foundational to the development and conduct of the KPMP. Herein, we use illustrative features of this research paradigm to develop a more comprehensive conceptualization of the types of benefits that may be important to research participants, including respecting pluralistic values, supporting the opportunity to act altruistically, and enhancing benefits to a participant's community. This approach may serve as a model to help researchers, ethicists, and regulators to identify opportunities to better respect and support participants in future research that entails some risk to these participants as well as to improve the quality of research for people with kidney disease.

Men's willingness to support HPV vaccination and cervical cancer screening in Nigeria.

Cervical cancer is the second most common female cancer in Nigeria, even though it can be prevented by vaccination and screening. The uptake of these preventive services is extremely low due to lack of spousal support and cost. Human papilloma virus (HPV) vaccines and cervical screening require finance as health services are mostly paid out of pocket. This study explored Nigerian men's willingness to encourage and pay for family member to obtain HPV vaccine and cervical screening. This is a cross-sectional study of 352 men aged 18-65 years living in 12 communities in the 6-geopolitical region. We found poor perception of HPV risk, and believed their family was not susceptible to cervical cancer. However, the majority (>80%) believed HPV vaccine and cervical screenings are important. Additionally, a good number (>58%) would encourage and pay for their family member to receive HPV vaccine and cervical screening. Residency, educational level and monthly income were significantly associated with willingness to encourage their family to receive HPV vaccine and cervical screening. Also, age group, marital status, residency, educational level and monthly income were significantly associated with the willingness to pay for HPV vaccine and cervical cancer screening. Majority were willing to encourage and pay for their family member to get vaccinated and receive cervical screening. This supports the findings that lack of male involvement may be an overlooked obstacle to cervical cancer prevention in developing countries.

Compounded bioidentical menopausal hormone therapy - a physician perspective.

One of the defining moments of the 80-year evolution of menopausal hormone therapy (MHT) was the 2002 reveal of the initial results of the combined hormone therapy arm of the Women's Health Initiative (WHI) clinical trial. The exodus from regulatory approved MHT was prompt and profound and accompanied by a rapid acceleration of the compounding pharmacy 'bioidentical' hormone therapy industry. Compounders had recruited prescribers and promoted compounded bioidentical hormone therapy (cBHT) well before the WHI, yet the startling results provided a catalyst that enabled a leap in production of compounded hormones that were variably regulated, basically unstudied, and inconsistently labeled. In this review, the story of the rise of cBHT and the regulatory double standard is eclipsed only by the 2020 findings and recommendations of the US National Academies of Science, Engineering, and Medicine. Their investigation, commissioned by the US Food and Drug Administration, was tasked to: provide an evidence-based summary of the clinical utility of cBHT; evaluate whether the evidence of safety and efficacy supports the use of cBHT; and identify patient populations that might need cBHT in lieu of an approved drug product. Their conclusions are consistent with sound science and their recommendations are in harmony with global menopause societies.

Participatory design and qualitative evaluation of a decision guide for workplace human immunodeficiency virus self-disclosure: The importance of a socio-ecological perspective.

BACKGROUND: Disclosure of human immunodeficiency virus (HIV)-positive status in a workplace can be a complex social decision for a person living with HIV. OBJECTIVE: To design a Decision Guide to support people living with HIV in assessing contexts, risks and benefits of workplace disclosure in choosing whether or not, or to what extent, to disclose. In this report, we review the participatory design of a Decision Guide prototype and focus on its evaluation. METHODS: We began with stakeholder input through an environmental scan and community consultation that informed the development of an online Decision Guide prototype. To evaluate the comprehensiveness, acceptability and usability of the prototype, we used qualitative methodology involving individual interviews and the think-aloud technique. Interviews were transcribed and analysed qualitatively. RESULTS: Fourteen people, including people living with HIV and service providers, participated. We identified benefits of the Decision Guide related to comprehensiveness, acceptability and usability. Additional interview themes focused on disclosure concerns, mitigating risks associated with disclosure and additional considerations for the Decision Guide. CONCLUSIONS: The Decision Guide was perceived to be acceptable, comprehensive and useful. The findings endorse the application of a socio-ecological perspective when designing decision support aids for complex social decisions. PATIENT OR PUBLIC CONTRIBUTION: People with lived experience of HIV were involved in the prototype design phases as research team members. They, along with community leaders and service providers, also participated in a community forum and were key informants for the evaluation of the Workplace Disclosure Decision Guide prototype.

Lessons Learned: Beta-Testing the Digital Health Checklist for Researchers Prompts a Call to Action by Behavioral Scientists.

Digital technologies offer unique opportunities for health research. For example, Twitter posts can support public health surveillance to identify outbreaks (eg, influenza and COVID-19), and a wearable fitness tracker can provide real-time data collection to assess the effectiveness of a behavior change intervention. With these opportunities, it is necessary to consider the potential risks and benefits to research participants when using digital tools or strategies. Researchers need to be involved in the risk assessment process, as many tools in the marketplace (eg, wellness apps, fitness sensors) are underregulated. However, there is little guidance to assist researchers and institutional review boards in their evaluation of digital tools for research purposes. To address this gap, the Digital Health Checklist for Researchers (DHC-R) was developed as a decision support tool. A participatory research approach involving a group of behavioral scientists was used to inform DHC-R development. Scientists beta-tested the checklist by retrospectively evaluating the technologies they had chosen for use in their research. This paper describes the lessons learned because of their involvement in the beta-testing process and concludes with recommendations for how the DHC-R could be useful for a variety of digital health stakeholders. Recommendations focus on future research and policy development to support research ethics, including the development of best practices to advance safe and responsible digital health research.

[Acceptance of assistive robots in the field of nursing and healthcare : Representative data show a clear picture for Germany]. / Akzeptanz von assistiven Robotern im Pflege- und Gesundheitsbereich : Repräsentative Daten zeichnen ein klares Bild für Deutschland.

In view of the ageing society and the high costs of support and care in private households, the question arises as to what role assistive robots can play. This article focuses on the extent to which robots in nursing are accepted by the adult population in Germany today, as well as the extent to which gender, age, and experience (professional and private) influence this level of acceptance. The analysis carried out for this purpose was based on three representative surveys conducted among a total of over 7000 respondents. Of these surveys two were conducted in the second half of 2017 on behalf of the German Academy of Science and Engineering (acatech) and the life insurance company ERGO, while the third was commissioned by the German Council of Economic Experts (SVRV) in the spring of 2018. An in-depth and cumulative analysis of these surveys and data sets, which the authors helped to design, with respect to assistive robotics has not yet been published. Despite the different application scenarios for assistive care robots, the results of all three surveys are surprisingly consistent: in Germany there is already a significant minority of people who are open to, and would accept nursing care robots as long as they do not replace but rather support traditional human nursing. Roughly one third of the sample differentiated according to age and gender, fundamentally rejected assistance by robots.

A failure in solidarity: Ethical challenges in the development and implementation of new tuberculosis technologies.

Prominent tuberculosis (TB) actors are invoking solidarity to motivate and justify collective action to address TB, including through intensified development and implementation (D&I) of technologies such as drugs and diagnostics. We characterize the ethical challenges associated with D&I of new TB technologies by drawing on stakeholder perspectives from 23 key informant interviews and we articulate the ethical implications of solidarity for TB technology D&I. The fundamental ethical issue facing TB technological D&I is a failure within and beyond the TB community to stand in solidarity with persons with TB in addressing the complex sociopolitical contexts of technological D&I. The failure in solidarity relates to two further ethical challenges raised by respondents: skewed power dynamics that hinder D&I and uncertainties around weighing risks and benefits associated with new technologies. Respondents identified advocacy and participatory research practices as necessary to address such challenges and to motivate sustained collective action to accelerate toward TB elimination. We present the first empirical examination of bioethical accounts of solidarity in public and global health. Our study suggests that solidarity allows us better to understand and address the ethical challenges that arrest the D&I of new TB technologies. Solidarity lends credence to policies and practices that address the relational nature of illness and health through collective action.

Choosing Pre-conception Planning for Women/Families: Counselling and Informed Consent (Part 2) - Pre-conception Reproductive Planning, Lifestyle, Immunization, and Psychosocial Issues.

OBJECTIVE: To inform reproductive and other health care providers about pre-conception evaluation, including considerations for reproductive planning, lifestyle modification, immunization status and attitudes, and psychosocial issues. OPTIONS: This counselling information can be used for patient education and planning and possible pre-conception and/or prenatal testing. OUTCOMES: This information may allow for improved risk assessment when pre-conception counselling for individual patients and their families is used. CONSIDERATIONS FOR PRE-CONCEPTION CARE (PART 2) REGARDING PRE-CONCEPTION REPRODUCTIVE PLANNING, LIFESTYLE, IMMUNIZATIONS, AND PSYCHOSOCIAL ISSUES: CONSIDERATION FOR CARE STATEMENTS: For this review article, the Consideration for Care Statements use the Grading of Recommendations, Assessment, Development and Evaluations strength and quality principles because they are comparable for the clinician and the patient/public user. For example, "Strong" for clinicians is defined as "the recommendation would apply to most individuals. Formal discussion aids are not likely to be needed to help individuals make decisions consistent with their values and preferences." For patients/the public, "Strong" is defined as, "we believe most people in this situation would want the recommended course of actions and only a small number would not." Quality of evidence (High, Moderate, Low) is based on the confidence that the true effect lies close to that of the estimate of the effect. In addition, the Canadian Task Force on Preventive Health Care key to evidence statements and grading of recommendations are included. EVIDENCE: PubMed, Medline, and the Cochrane Database were searched until May 2017, using appropriate key words (i.e., preconception, reproductive planning, lifestyle modification, immunization risks and benefits, psychosocial pregnancy factors/issues). Grey (unpublished) literature was identified through searching websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, and national and international medical specialty societies. BENEFITS, HARMS, AND COSTS: The benefits for the patient and her family from receiving this pre-conception counseling would include an increased understanding of the relevant issues for both pre-conception and in early pregnancy as well as better pregnancy outcomes. Harm includes potential increased anxiety or psychological stress associated with the possibility of identifying maternal pregnancy risks.

Mineral Content of Various Portuguese Breads: Characterization, Dietary Intake, and Discriminant Analysis.

The chemical composition and daily mineral intake (DMI) of six macro (calcium, magnesium, sodium, potassium, phosphorous, and chloride) and four microminerals (copper, iron, manganese, and zinc) were determined in four types of Portuguese breads (white wheat, maize, wheat/maize, and maize/rye breads). Samples were processed with microwave assisted digestion and mineral composition was determined with a high-resolution continuum-source atomic absorption spectrometer with flame and graphite furnace. Bread contributes to an equilibrated diet since it is rich in several minerals (0.21 mg/100 g of copper in wheat bread to 537 mg/100 g of sodium in maize/rye bread). Maize/rye bread presented the highest content of all minerals (except phosphorous and chloride), while the lowest levels were mainly found in wheat bread. Median sodium concentrations (422-537 mg/100 g) represented more than 28% of the recommended daily allowance, being in close range of the maximum Portuguese limit (550 mg/100 g). Maize/rye bread exhibited the highest DMI of manganese (181%), sodium (36%), magnesium (32%), copper (32%), zinc (24%), iron (22%), potassium (20%), and calcium (3.0%). A Principal Component Analysis (PCA) model based on the mineral content allowed the differentiation among white wheat, maize, and maize/rye bread. Zinc, magnesium, manganese, iron, phosphorus, potassium, copper, and calcium proved to be good chemical markers to differentiate bread compositions.

Survey of risks and benefits communication strategies by research nurses.

BACKGROUND: An ethical, informed consent process requires that potential participants understand the study, their rights, and the risks and benefits. Yet, despite strategies to improve communication, many participants still lack understanding of potential risks and benefits. Investigating attitudes and practices of research nurses can identify ways to improve the informed consent process. RESEARCH QUESTION: What are the attitudes, practices, and preparedness of nurses involved in the informed consent process regarding communication of risks and benefits? RESEARCH DESIGN: A survey was developed and administered online to a national purposive sample of 107 research nurses with experience obtaining informed consent for clinical trials. Survey responses stratified by selected work-related characteristics were analyzed. ETHICAL CONSIDERATIONS: Participants were instructed they need not answer each question and could stop at any time. They consented by clicking "accept" on the email which linked to the survey. The study was approved by the Northeastern University Institutional Review Board, Boston, Massachusetts (NU-IRB Protocol #: 13-06-17). FINDINGS: Most research nurses (87%) used a teach-back method to assess participant comprehension, while 72% relied on their intuition. About one-third did not feel prepared to communicate related statistics. About 20% did not feel prepared to tailor information, and half did not feel competent using supplemental materials to enhance risks and benefits comprehension. Only 70% had received training in the informed consent process which included in-person training (84%), case studies (69%), online courses (57%), feedback during practice sessions (54%), and simulation, such as role playing (49%) and viewing videos (45%). Perceived preparedness was significantly associated with greater informed consent experience and training. CONCLUSION: Research nurses may have inadequate training to encourage, support, and reinforce communication of risks and benefits during the informed consent process. Relevant purposeful education and training should help to improve and standardize the ethical informed consent process.

Age and perceived risks and benefits of preventive genomic screening.

PURPOSE: As genome sequencing moves from research to clinical practice, sequencing technologies focused on "medically actionable" targets are being promoted for preventive screening despite the dearth of systematic evidence of risks and benefits and of criteria for selection of screening subjects. This study investigates researchers' and research participants' perceptions of these issues within the context of a preventive genomic screening study, GeneScreen. METHODS: We recorded researcher deliberations regarding age eligibility criteria and the risks and benefits of screening, and conducted interviews with 50 GeneScreen participants about their motivations for joining and their perceptions of risks and benefits. RESULTS: Researchers made assumptions about who would want and benefit from screening based on age. After discussion, researchers opted not to have an upper age limit for enrollment. Participants of all ages perceived similar benefits, including prevention, treatment, and cascade testing, and similar risks, such as insurance discrimination and worry. CONCLUSION: While clinical benefits of preventive genomic screening for older adults are debatable, our respondents perceived a range of benefits of screening in both clinical and research settings. Researchers and clinicians should carefully consider decisions about whether to exclude older adults and whether to provide information about benefits and risks across age groups.

How to Perform an Ethical Risk Analysis (eRA).

Ethical analysis is often needed in the preparation of policy decisions on risk. A three-step method is proposed for performing an ethical risk analysis (eRA). In the first step, the people concerned are identified and categorized in terms of the distinct but compatible roles of being risk-exposed, a beneficiary, or a decisionmaker. In the second step, a more detailed classification of roles and role combinations is performed, and ethically problematic role combinations are identified. In the third step, further ethical deliberation takes place, with an emphasis on individual risk-benefit weighing, distributional analysis, rights analysis, and power analysis. Ethical issues pertaining to subsidiary risk roles, such as those of experts and journalists, are also treated in this phase. An eRA should supplement, not replace, a traditional risk analysis that puts emphasis on the probabilities and severities of undesirable events but does not cover ethical issues such as agency, interpersonal relationships, and justice.

Serial Participation and the Ethics of Phase 1 Healthy Volunteer Research.

Phase 1 healthy volunteer clinical trials-which financially compensate subjects in tests of drug toxicity levels and side effects-appear to place pressure on each joint of the moral framework justifying research. In this article, we review concerns about phase 1 trials as they have been framed in the bioethics literature, including undue inducement and coercion, unjust exploitation, and worries about compromised data validity. We then revisit these concerns in light of the lived experiences of serial participants who are income-dependent on phase 1 trials. We show how participant experiences shift attention from discrete exchanges, behaviors, and events in the research enterprise to the ongoing and dynamic patterns of serial participation in which individual decision-making is embedded in collective social and economic conditions and shaped by institutional policies. We argue in particular for the ethical significance of structurally diminished voluntariness, routine powerlessness in setting the terms of exchange, and incentive structures that may promote pharmaceutical interests but encourage phase 1 healthy volunteers to skirt important rules.

[State of contraception in 2016]. / Etat de la contraception en 2016.

INTRODUCTION: The Pill and other forms of hormonal contraception, if taken correctly, are very effective and safe for millions of women, but since a few years, due to the debates and controversies about the third- and fourth-generation pills, other options have gained in popularity. OBJECTIVES: to provide a review of oestroprogestative contraception (OP), progesta-tive contraception, IUDs with a focus on their advantages and side-effects according to the specific needs of women. METHODS: literature review and lessons learned from clinical practice. RESULTS: The importance of family and individual history, the life-style and socio-economic conditions are critical factors for advising women on the 15 contraceptive choices available to them. The risk/benefit ratio of OP contraception needs a yearly follow-up. The progestative contraception is the preferred option for women who have contraindication for oestrogen, are older than forty, and/or have risk factors such as a history of venous thromboembolism, overweight and smoking. The IUD usually is well tolerated and causes few side effects. Among the other contraceptive methods, sterilization and diaphragms are briefly discussed. CONCLUSION: Among the many safe and effective contraceptive methods, it is important for general practitioners to know the advantages and the side effects of each method, as well as the specific conditions of the woman, to propose the best options available. In case of difficulties of follow up or adherence to daily uptake, in particular among adolescents, long-acting methods such as IDU or implants are preferable.

INTRODUCTION: Longtemps préférées des femmes, les pilules sont en recul en Belgique depuis les polémiques sur les pilules de 3e et 4e génération. Si le recours à la contraception orale a diminué, d'autres prat iques contraceptives se sont renforcées. OBJECTIFS: fournir une description détaillée des contraceptifs oestroprogestatifs (OP), des contraceptifs à base de progestatifs seuls et des dispositifs intra-utérins, en soulignant leur intérêt mais aussi les risques de leur utilisation. METHODE: revue de la littérature et expérience clinique. RESULTATS: l'importance des antécédents personnels, familiaux, et du style de vie est déterminante pour évaluer les indications des différentes méthodes. En ce qui concerne les contraceptifs OP, le rapport risque/bénéfice nécessite un suivi annuel. La contraception progestative est une option choisie par de nombreuses femmes, particulièrement celles qui ont plus de 40 ans, et/ou des facteurs de risque comme le tabac, le surpoids ou des antécédents de TEV. Le dispositif intra-utérin est généralement bien toléré comme méthode contraceptive car il présente peu d'effets secondaires ou de complications. Parmi les autres méthodes contraceptives, la stérilisation féminine et le diaphragme sont brièvement discutés. CONCLUSION: Parmi les nombreuses possibilités de choix contraceptifs, il est important de faire connaître les indications et contre-indications en tenant compte de la situation de la personne. En cas de difficulté de suivi et d'observance, en particulier chez les adolescentes, la prescription des méthodes à longue durée d'action est préférable.

Oestrogen-based therapies for menopausal symptoms.

PURPOSE: To summarise the dosing options, regimens, pharmacokinetics, risks and benefits of oestrogen-based therapies for the treatment of menopausal symptoms. METHODS: A review of the literature was undertaken using multiple databases. Randomised trials, observational studies, meta-analyses and review papers were included. RESULTS: Multiple systemic preparations of oestrogen exist and all appear comparable in terms of efficacy. They differ by pharmacokinetics and those preparations that avoid hepatic metabolism have a lower risk profile in general although their use can be limited by skin barriers or patient acceptability. All vaginal oestrogen treatments are comparable in efficacy and have not been associated with any health risks. Side-effects between all preparations differ. CONCLUSIONS: With regards to oestrogen treatments there is not a one size fits all. Multiple treatments are available and a clinician's role is to guide and help women make evidence based, unbiased and informed choices.

Lingual orthodontic treatment: what is the current evidence base?

As the number of adults that seek orthodontic treatment continues to grow, so too is the popularity of lingual fixed appliances. Although the aesthetic advantages associated with these systems are obvious, for some orthodontists, there has been a reluctance to offer lingual-based treatment to their patients. This is often based upon the perceived problems associated with lingual braces, relating to discomfort and difficulties with speech for the patient, and problems in using these appliances for the orthodontist. Although some of these factors have been investigated, the current evidence base is weak, possibly due to the fact that these are evolving appliance systems. Among the studies that have been carried out to date, pain and discomfort for the patient appears to be similar following the placement of labial or lingual appliances, although the onset can be earlier with lingual brackets and the location different, with the tongue more frequently being involved. Customized lingual brackets may be associated with less pain than pre-fabricated. In addition, patients do seem to be more likely to experience difficulties with speech and mastication when fitted with a lingual appliance. However, there is some evidence that the lingual surfaces of the teeth are more resistant to early demineralization and caries. Little data exist regarding treatment outcome and ease of use for the orthodontist, either between lingual or labial appliances or between different lingual systems. Further research is required to investigate the efficiency of lingual appliance systems, both for the patient and orthodontist.

Three-Dimensional Printing of Foods: A Critical Review of the Present State in Healthcare Applications, and Potential Risks and Benefits.

Three-dimensional printing is one of the most precise manufacturing technologies with a wide variety of applications. Three-dimensional food printing offers potential benefits for food production in terms of modifying texture, personalized nutrition, and adaptation to specific consumers' needs, among others. It could enable innovative and complex foods to be presented attractively, create uniquely textured foods tailored to patients with dysphagia, and support sustainability by reducing waste, utilizing by-products, and incorporating eco-friendly ingredients. Notable applications to date include, but are not limited to, printing novel shapes and complex geometries from candy, chocolate, or pasta, and bio-printed meats. The main challenges of 3D printing include nutritional quality and manufacturing issues. Currently, little research has explored the impact of 3D food printing on nutrient density, bioaccessibility/bioavailability, and the impact of matrix integrity loss on diet quality. The technology also faces challenges such as consumer acceptability, food safety and regulatory concerns. Possible adverse health effects due to overconsumption or the ultra-processed nature of 3D printed foods are major potential pitfalls. This review describes the state-of-the-art of 3D food printing technology from a nutritional perspective, highlighting potential applications and current limitations of this technology, and discusses the potential nutritional risks and benefits of 3D food printing.

High-Dose Prophylactic Anticoagulation for COVID-19 Pneumonia: A Review of Benefits and Risks.

The COVID-19 pandemic has had a devastating impact on a global scale, causing significant morbidity and mortality. The virus affects multiple organ systems, including the respiratory, cardiovascular, and coagulation systems, leading to severe pneumonia in some patients. Moreover, COVID-19 patients with severe pneumonia have a high incidence of thrombotic events, which can result in significant morbidity and mortality. Given the potential benefits of anticoagulation therapy in COVID-19 patients with thrombotic complications, recent studies have proposed high-dose prophylactic anticoagulation (HD-PA) therapy as a potential treatment option. In fact, some studies have suggested that HD-PA therapy may be more effective in reducing thrombotic events and mortality rates than other treatment options. This review aims to provide a comprehensive overview of the benefits and risks of HD-PA therapy for COVID-19 pneumonia patients. By synthesizing and analyzing the latest available research, we highlight patient selection criteria and discuss the optimal dosage, duration, and timing of therapy. Additionally, we review the potential risks associated with HD-PA therapy and provide recommendations for clinical practice. Ultimately, this review provides valuable insights into the use of HD-PA therapy in COVID-19 pneumonia patients and paves the way for further research in this critical area. By exploring the benefits and risks of this treatment option, we hope to provide healthcare professionals with the information they need to make informed decisions about the best course of treatment for their patients.

Nutritional profiling and contaminant levels of five underutilized fish species in Norway.

Exploring and making use of underutilized marine resources can be a sustainable approach to achieve future demands of fish consumption by the ever-growing population. Five species, namely European plaice (Pleuronectes platessa), European flounder (Platichthys flesus), lemon sole (Microstomus kitt), megrim (Lepidorhombus whiffiagonis), and thornback ray (Raja clavate), often captured as by-catch in Norway, were characterized for their nutritional value and potential accumulation of hazardous components. The proximate composition, protein profile, fatty acid profile as well as essential and toxic trace elements and polychlorinated biphenyls (PCBs) were analyzed. Digestible indispensable amino acid (DIAA) ratios and scores (DIAAS) and contributions of omega-3 fatty acids to the diet were calculated. Analysis on proximate composition revealed low fat contents of 0.74 to 1.25% and sufficient protein contents between 16.9 and 24% in the five species. Results of DIAA indicate a profitable distribution, with contributions exceeding the daily intake recommendations for an adult person related to a 200 g fillet. Moreover, findings on the distribution of eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) showed remarkable results, considering that the investigated species are lean fish. All five investigated fish exceed the recommended average daily intake level (AI) of EPA + DHA in a 200 g portion. As to toxic trace elements and PCBs, no significantly elevated levels were found considering a portion size of 200 g. Consequently, the nutritional quality of the investigated fish can be regarded as profitable with overall low potential health risks.
