The EU (7)-PIM list was created for the European market to improve pharmacotherapy in older adults.Purpose: This work aims to characterize the medication profile and assess the presence of PIM, using the EU (7)-PIM list in older adults’ residents at nursing homes.Methods: Retrospective data were collected from the anonymized nursing home records. After PIM identification, a descriptive analysis was performed, and a generalized linear model for dependent negative binomial-type variables was constructed to assess the risk of PIM.Results: Of the 210 participants (mean age 85.10), 82.40% were polymedicated. PIM was observed in 86.4% participants (mean per patient = 2.30± 0.10). The most common PIM were proton pump inhibitors (n = 121, 57.62%), followed by anxiolytics (n = 96, 45.71%). 64.30% of all patients take 2– 4 PIM and 5.80% take five or more PIM. The occurrence of PIM is influenced by the number of prescribed medicines (RR 1.14; 95% CI 1.1.-1.17) and the presence of digestive system diseases (RR 1.05; 95% CI 1.0– 1.09).Conclusion: The high prevalence of PIM observations highlights the necessity of the implementation of guidelines to prevent PIM.Keywords: elderly, institutionalized older adults, medication profile, prescription

Objective: Characterization of the adverse drug reactions (ADR) reported by the immunoallergology department (IAD), Centro Hospitalar de São João (Porto), to the Northern Pharmacovigilance Centre (NPC). Methods: An observational, descriptive and retrospective study was conducted, based in a spontaneous report system. Participants were all the patients from the IAD, with suspected ADR, reported to NPC by specialists after the study was completed. Results: Studied population had a median age of 41 years, with the predominance of the female gender (73.2%). Allergic rhinitis and asthma were the most frequent comorbidities. All studied ADR were type B, 89.6% were serious, 86.4% unexpected and 2.6% associated with drugs that presented less than 2 years in the market. The most represented drug classes were the non-steroidal anti-inflammatory drugs (NSAIDs) (52.6%) and antibiotics (25.2%). Skin symptoms represented 61.2% of the reported complaints. About 52.9% of these ADR occurred in less than one hour after intake. The most frequent ADR treatment at the time of the reaction was drug interruption (86.2%), followed by the prescription of anti-histamines (42.2%). Conclusions: Reported ADR to NPC by the Drug Alert Unit were mainly serious, unexpected, associated with NSAIDs and antibiotics and related with marketing authorization medicines older than two years. These results could be very useful to develop strategies to prevent the clinical and economic consequences of ADR.

Introduction: Considering the increase in the proportion of the older population worldwide, the demand for health system resources also arises. These tools optimize clinical decision-making, thus avoiding iatrogenesis and thus contributing to a better quality of life for the older population. In response, we created an online web application, the APIMedOlder, that provides access to healthcare professionals to allow healthcare professionals to access potentially inappropriate medication identification criteria through a useful tool with a simplified profile, allowing its applicability in clinical practice. This study aims to assess the usability of the APIMedOlder online web application by healthcare professionals., Methods: A questionnaire, based on the System Usability Scale, was distributed among 15 healthcare professionals (five pharmacists, four physicians, three pharmacy technicians, and three nurses), to fully explore the website., Results: Overall, healthcare professionals' evaluation of the usability of the APIMedOlder online web application was rated as "Best imaginable" (mean score of 87.17 points), with individual scores ranging from 75 to 100 points. Internal consistency of α = 0.881 (CI 95%: 0.766 - 0.953) was achieved. Specific questionnaire items contributing to this high score included ease of use, learning efficiency, and integration of functions., Conclusion: The overall evaluation of the developed tool was positive, with this online application being recognized as being easy to use and having well-integrated functions.

The European Medicines Agency adopted their Geriatric Medicines Strategy more than a decade ago. The strategy aims at elucidating the evidence basis for marketing authorization of new medicines which will be used in the older population, and at ensuring the appropriate communication of findings to the patient and healthcare provider. During the past decade new tools and data sources have emerged to support the strategy goals, and their use should be considered. Possible concrete actions are presented to improve the design of clinical trials, the data collection both pre- and post-approval, the assessment of the findings, and the communication to assist informed prescription and safe medicine taking. Implementation and prioritization of these actions should be done from the perspective of addressing the needs of patients while maximizing efficient use of resources, with the aim of integrating geriatric aspects into routine medicines development and assessment., (© 2024 The Authors.

Prostate cancer (PCa) accounts for 20% of new cancer cases and 10.5% of cancer-associated mortality in Portugal. Associated risk factors include advanced age, family history, genetic alterations, and race/ethnicity. However, the role of lifestyle factors is often underestimated. To explore health professionals' perceptions of PCa risk factors, a qualitative study with three focus groups (FG), with a total of twenty-one general practitioners and urologists, was conducted via videoconference between February and April 2023. Seven themes emerged, including general perceptions of PCa; PCa risk factors; nutritional impact; the role of physical activity; alcohol consumption and smoking; sexual activity and sexually transmitted diseases roles in PCa; and screening, diagnosis, and treatment methods. Despite agreeing that healthy lifestyles could promote better PCa outcomes and quality of life, participants did not specify any lifestyle factors that could promote or prevent this disease, posing challenges to lifestyle changes, particularly among older adults. Non-invasive screening methods, such as biomarkers and alternative treatments, are crucial for future research. This study underscores the need for further investigation into the correlation of lifestyle factors with PCa and highlights the necessity of health professionals in encouraging their patients to adopt healthier lifestyles, while offering important insights into awareness, prevention, and alternative screening, diagnosis, and treatment methods, which could help reduce false positives and treatment side effects.

Nodular thyroid pathologies (NThyPs) are prevalent thyroid diseases, with a steadily increasing global incidence. Although their exact causes remain uncertain, various modifying factors, such as nutrition, influence their development. We aimed to systematically identify and synthesize the influence of dietary exposures on NThyPs risk. PubMed, Scopus, Web of Science, and EMBASE were searched on June 14, 2024, to identify relevant studies. Data extraction included study characteristics, sociodemographic factors, dietary intake assessments and exposures, and NThyPs subtypes. Out of 14,730 articles retrieved, 55 observational or experimental studies, in English, Spanish, or Portuguese, that assessed nutrition's impact on NThyPs were included, excluding non-human studies, reviews, meta-analyses, and publications outside the study's scope. Forty studies investigated how distinct dietary patterns, macronutrients, minerals, and vitamins contributed to or mitigated NThyPs development. Fish and seafood, vegetables and fruits, and meat were other dietary exposures investigated. In fourteen of previously selected studies, drink consumption was also addressed. This systematic review (CRD420234003439) suggests that reducing processed foods, sugars, meat, and dietary iodine lowers NThyPs risk, while coffee, tea, alcohol, and dairy products demonstrates potential protective roles. Fish and seafood, and fruits and vegetables also exhibit protective properties; nevertheless, further research is necessary to establish definitive conclusions.

Background: Considering the vulnerability of older adults to adverse drug reactions, medications with strong anticholinergic properties are considered potentially inappropriate for this population. This study aims to characterize older adults' profile of anticholinergics use and to identify the factors associated with their potentially inappropriate use., Research Design and Methods: A retrospective study was conducted on 1200 older adults in primary health care centers of Portugal between April 2021 and August 2022. Potentially inappropriate use was assessed according to the 2023 Beers criteria. Logistic regression analyses were performed to determine associations between independent variables and potentially inappropriate use., Results: A 8.9% (95% CI 0.074-0.107) of the older adults were exposed to one or more potentially inappropriate anticholinergics, and amitriptyline was the most used (2.0%). Multivariate analysis revealed that use was associated with a higher mean number of medications (OR 1.173, 95% CI 1.115-1.234), diagnoses of depression (OR 2.889, 95% CI 1.785-4.674) and psychiatric disorders (OR 1.654, 95% CI 1.003-2.729)., Conclusions: This study underscores the importance of vigilance in prescribing anticholinergic medications to older adults, particularly those with higher medication burdens and mental health diagnoses. By identifying factors associated with potentially inappropriate use, healthcare providers can better tailor medication regimens to mitigate risks and optimize the well-being of older adults.

Objective: This study aims to explore dentists' knowledge, attitudes, and perceptions regarding antibiotic use., Methods: We conducted a systematic review of dentists' knowledge, attitudes and perceptions regarding antibiotic use, by searching the MEDLINE, EMBASE and Web of Science for all original paper published from January 1990 to July 2023, in accordance with the Preferred Reporting Items for systematic Reviews and Meta-analyses (PRISMA 2020) guidelines., Results: The review included 37 papers, (7 qualitative and 30 quantitative studies). Modifiable factors (knowledge, attitudes) were reported as being associated with antibiotic prescribing by dentists which were cited in 30 of the 37. These attitudes most frequently identified by dentists were: complacency (22/29); lack of trust (16/29); the need to postpone the dental procedure (17/29); and fear (8/29). Gaps in knowledge were also identified (15/29). Only one of the included articles quantified the influence between the reported modifiable factors and antibiotic prescribing., Conclusions: The review emphasizes that dentists' antibiotic prescribing is predominantly influenced by modifiable factors. This insight informs the potential for targeted interventions to curtail inappropriate antibiotic use, contributing to global efforts in reducing antibiotic resistance.

Background: At the time of the emergence of COVID-19, denialist and anti-vaccine groups have also emerged and are shaking public confidence in vaccination., Methods: A qualitative study was conducted using online focus groups. Participants had not received any doses of vaccination against the disease. A total of five focus group sessions were conducted with 28 participants. They were recruited by snowball sampling and by convenience sampling., Results: The two major topics mentioned by the participants were adverse effects and information. The adverse effects described were severe and included sudden death. In the case of information, participants reported: (1) consultation of websites on which scientists posted anti-vaccination content; and (2) distrust., Conclusions: At a time when anti-vaccine groups pose a major challenge to public health in general, and to COVID-19 vaccination campaigns in particular, this study is a first step towards gaining deeper insight into the factors that lead to COVID-19 vaccine refusal., (© 2024.

In pharmacovigilance, disproportionality analyses based on individual case safety reports are widely used to detect safety signals. Unfortunately, publishing disproportionality analyses lacks specific guidelines, often leading to incomplete and ambiguous reporting, and carries the risk of incorrect conclusions when data are not placed in the correct context. The REporting of A Disproportionality analysis for drUg Safety signal detection using individual case safety reports in PharmacoVigilance (READUS-PV) statement was developed to address this issue by promoting transparent and comprehensive reporting of disproportionality studies. While the statement paper explains in greater detail the procedure followed to develop these guidelines, with this explanation paper we present the 14 items retained for READUS-PV guidelines, together with an in-depth explanation of their rationale and bullet points to illustrate their practical implementation. Our primary objective is to foster the adoption of the READUS-PV guidelines among authors, editors, peer reviewers, and readers of disproportionality analyses. Enhancing transparency, completeness, and accuracy of reporting, as well as proper interpretation of their results, READUS-PV guidelines will ultimately facilitate evidence-based decision making in pharmacovigilance., (© 2024. The Author(s).)

Background and Aim: Disproportionality analyses using reports of suspected adverse drug reactions are the most commonly used quantitative methods for detecting safety signals in pharmacovigilance. However, their methods and results are generally poorly reported in published articles and existing guidelines do not capture the specific features of disproportionality analyses. We here describe the development of a guideline (REporting of A Disproportionality analysis for drUg Safety signal detection using individual case safety reports in PharmacoVigilance [READUS-PV]) for reporting the results of disproportionality analyses in articles and abstracts., Methods: We established a group of 34 international experts from universities, the pharmaceutical industry, and regulatory agencies, with expertise in pharmacovigilance, disproportionality analyses, and assessment of safety signals. We followed a three-step process to develop the checklist: (1) an open-text survey to generate a first list of items; (2) an online Delphi method to select and rephrase the most important items; (3) a final online consensus meeting., Results: Among the panel members, 33 experts responded to round 1 and 30 to round 2 of the Delphi and 25 participated to the consensus meeting. Overall, 60 recommendations for the main body of the manuscript and 13 recommendations for the abstracts were retained by participants after the Delphi method. After merging of some items together and the online consensus meeting, the READUS-PV guidelines comprise a checklist of 32 recommendations, in 14 items, for the reporting of disproportionality analyses in the main body text and four items, comprising 12 recommendations, for abstracts., Conclusions: The READUS-PV guidelines will support authors, editors, peer-reviewers, and users of disproportionality analyses using individual case safety report databases. Adopting these guidelines will lead to more transparent, comprehensive, and accurate reporting and interpretation of disproportionality analyses, facilitating the integration with other sources of evidence., (© 2024.

Purpose: This study aims to identify PIM prevalence in older adults according to the 2019 Beers criteria, Screening Tool of Older Person's Prescriptions version 2 (STOPP v2) criteria, and the Portuguese EU(7)-PIM list and also to analyze the concordance between these criteria., Methods: A retrospective study was conducted among 1200 Portuguese older adults (≥ 65 years old), users of primary health care. Demographic, clinical, and pharmacological data were collected concerning the period between April 2021 and August 2022. A comparative analysis was performed between the three PIM identification criteria, and the concordance was determined according to the Lin concordance correlation coefficient., Results: The mean age was 76.3 (SD 7.7) years old and 57.6% of the older adults were females. Our findings indicate varying prevalence rates among these criteria with 63.8% (95% CI 61.0-66.6%), 66.8% (95% CI 64.1-69.5%), and 50.1% (95% CI 47.2-53.0%) of the older adults take at least one PIM according to the EU(7)-PIM list, Beers 2019, and STOPP v2 criteria, respectively. The highest prevalence observed was for proton pump inhibitors according to EU(7)-PIM list (30.1%, 95% CI 27.6-32.9) and Beers criteria (30.1%, 95% CI 27.6-32.9) and alprazolam according to STOPP v2 criteria (10.1%, 95% CI 8.4-11.9%). A poor concordance between criteria was observed (< 0.834). The highest concordance coefficient was found between the EU(7)-PIM list and the Beers criteria (0.833), and the lowest between the EU(7)-PIM list and STOPP criteria (0.735)., Conclusion: This study reveals varying prevalence rates of PIM in older adults, as assessed by different criteria, and highlights the need for targeted interventions and improved prescribing practices. In the future, studies should focus on the occurrence of negative outcomes in older adults associated with PIM consumption., (© 2024. The Author(s).)

Background: The association between use of antipsychotics and COVID-19 outcomes is inconsistent, which may be linked to use of these drugs in age-related diseases. Furthermore, there is little evidence regarding their effect in the nongeriatric population. We aim to assess the association between antipsychotic use and risk of disease progression and hospitalization due to COVID-19 among the general population, stratifying by age., Methods: We conducted a population-based, multiple case-control study to assess risk of hospitalization, with cases being patients with a PCR(+) test who required hospitalization and controls being individuals without a PCR(+) test; and risk of progression to hospitalization, with cases being the same as those used in the hospitalization substudy and controls being nonhospitalized PCR(+) patients. We calculated adjusted odds-ratios (aOR) and 95% confidence intervals (CI), both overall and stratified by age., Results: Antipsychotic treatment in patients younger than 65 years was not associated with a higher risk of hospitalization due to COVID-19 (aOR 0.94 [95%CI = 0.69-1.27]) and disease progression among PCR(+) patients (aOR 0.96 [95%CI = 0.70-1.33]). For patients aged 65 years or older, however, there was a significant, increased risk of hospitalization (aOR 1.58 [95% CI = 1.38-1.80]) and disease progression (aOR 1.31 [95% CI = 1.12-1.55])., Conclusions: The results of our large-scale real-world data study suggest that antipsychotic use is not associated with a greater risk of hospitalization due to COVID-19 and progression to hospitalization among patients younger than 65 years. The effect found in the group aged 65 years or older might be associated with off-label use of antipsychotics., (© The Author(s) 2024. Published by Oxford University Press on behalf of CINP.)

Purpose: Proton Pump Inhibitors (PPIs) have been associated with several adverse effects of particular concern in older populations. Their use for a period longer than 8 weeks is not recommended for older adults. Strategies to discontinue PPIs have been offered; however, their use remains high. This study aims to characterize PPI use in Portuguese older people and to identify the factors associated with potentially inappropriate use., Methods: A cross-sectional study was conducted on 1200 randomly selected older adults (≥65 years of age), users of primary health care facilities in the Regional Health Administration (Administração Regional de Saúde of Centro [ARSC]) of Portugal between April 2021 and August 2022. Data concerning their characteristics and PPI use were provided by the Shared Services of the Health Ministry (Serviços Partilhados do Ministério da Saúde) and collected retrospectively. Associations between independent variables and PPI use were investigated by logistic regression analysis., Findings: Of the older adults, 37.92% were receiving PPIs and 78.68% of them were taking them for a longer period than recommended; 49.79% were taking PPIs without having any digestive system-related disease. Multivariate analysis showed that the prolonged use of PPIs was not associated with any specific pattern, although inappropriate PPI use is high among Portuguese older adults., Implications: Long-term PPI use in older adults is widespread and does not fit any particular patient profile; therefore, cross-cutting educational interventions should be designed independently of the patient's pathologic condition or treatment., Competing Interests: Declaration of Competing Interest Daniela A. Rodrigues reports financial support was provided by Fundação para a Ciência e a Tecnologia.

Objective: Digital health is described as the use and development of all types of digital technologies to improve health outcomes. It could be used to prevent medication errors, a priority for health systems worldwide. However, the adoption of such tools remains slow. This study aims to identify factors (attitudes, knowledge and beliefs) acting as barriers and/or facilitators reported by healthcare professionals (HCPs) for the adoption of digital health-related tools for medication appropriateness., Methods: A systematic review was performed by searching the literature in the MEDLINE PubMed, and EMBASE scientific databases for original articles regarding qualitative and quantitative data., Results: Fifteen articles were included and a total of 125 barriers and 108 facilitators were identified, consolidated and categorized into technical (n = 48), organizational (n = 12), economical (n = 4), user-related (n = 34), and patient-related (n = 8) components. The most often reported barriers and facilitators were technical component-related ones concerning the need for additional training (n = 6), the time consumed (n = 6), and the easy way of using or learning how to use the tools (n = 9), respectively. Regarding setting analysis, agreement with clinical decision recommendations and impact on the doctor-patient relationship were more valued in primary care, while the user interface and system design were in the hospital., Conclusions: The barriers and facilitators identified in this study provide relevant information to developers and it can be used as a starting point for the designing of successful digital health-related tools, specifically related to medication appropriateness. Future research includes economic evaluation-focused studies and in-depth case studies of specific barriers and facilitators., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Objectives: In terms of vaccination, people trust healthcare professionals (HCPs) more than any other source of information. They are the cornerstone of vaccination as they can move undecided populations not only towards vaccination but also towards non-vaccination. The aim of this systematic review was to explore the knowledge, beliefs, attitudes, and barriers associated with own vaccination and patient recommendation in HCPs., Study Design: This study incorporated a systematic review., Methods: A systematic review of studies published from January 1, 2000, to June 1, 2020, was conducted by searching PubMed and EMBASE electronic databases. Qualitative studies reporting outcomes related to knowledge, attitudes, or barriers related to vaccination/recommendation by healthcare personnel were included. The guidelines in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses were followed., Results: From a total of 2916 studies identified, 36 articles met the inclusion criteria. Some of the factors cited by the HCP that may contribute to vaccine hesitancy were (a) concerns regarding safety or efficacy of vaccines (23 articles); (b) time constraints (21 articles); (c) lack of knowledge about the vaccination/vaccine (19 articles); (d) costs (13 articles); (e) distrust of pharmaceutical industry (8 articles); and (f) considering oneself insusceptible (7 articles), stock shortage (7 articles), lack of personnel (5 articles), and feelings of unnecessary vaccination (5 articles)., Conclusions: Our review suggests that interventions to combat vaccine hesitancy should increase HCP education on vaccine efficacy and safety, as well as intervene on health system factors such as cost and time per visit. In this way, we could tackle the problem of vaccine hesitancy, which seriously threatens global public health., (Copyright © 2023 The Authors. Published by Elsevier Ltd.. All rights reserved.)

The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) E7, the guidance for the conduct of clinical trials in people older than age 65 years, dates from 1994. Since then, the inclusion of older people in clinical trials has hardly improved, particularly for the oldest old age group (individuals older than age 75 years), which is the fastest growing demographic bracket in the EU. Even though most medications are taken by this group, relevant endpoints and safety outcomes for this cohort are rarely included and reported, both in clinical trials and regulatory approval documents. To improve the critical appraisal and the regulatory review of medicines taken by frail older adults, eight recommendations are presented and discussed in this Health Policy. These recommendations are brought together from different perspectives and experience of the treatment of older patients. On one side, the perspective of medical practitioners from various clinical disciplines, with their direct experience of clinical decision making; on the other, the perspective of regulators assessing the data submitted in medicine registration dossiers, their relevance to the risk-benefit balance for older patients, and the communication of the findings in the product information. Efforts to improve the participation of older people in clinical trials have been in place for more than a decade, with little success. The recommendations presented here are relevant for stakeholders, authorities, pharmaceutical companies, and researchers alike, as the implementation of these measures is not under the capacity of a single entity. Improving the inclusion of frail older adults requires awareness, focus, and action on the part of those who can effect a much needed change., Competing Interests: Declaration of interests CL reports research support from Pfizer and Gilead Sciences, is one of the inventors and patent owners of Creatan Iama Olvos Science, has received payment for expert testimonies from WHO and the European Commission, and has served on advisory boards for MSD, Pfizer Hellas, and Vianex.

Background: Spontaneous reporting is the most used method to monitor post-marketing safety information. Although patient involvement in spontaneous reporting has increased overtime, little is known about factors associated with patients' adverse drug reaction (ADR) reporting., Aim: To identify and assess the sociodemographic characteristics, attitudes and knowledge that influence spontaneous reporting and the reasons associated with ADR underreporting by patients., Method: A systematic review was conducted according to PRISMA guidelines. A search on the MEDLINE and EMBASE scientific databases was performed to retrieve studies published between 1 January 2006 and 1 November 2022. Studies were included if they addressed knowledge and attitudes associated with ADR underreporting., Results: A total of 2512 citations were identified, of which 13 studies were included. Sociodemographic characteristics were frequently identified with ADR reporting in 6 studies, being age (3/13) and level of education (3/13) the most often reported. Older age groups (2/13) and individuals with higher level of education (3/13) were more likely to report ADRs. Underreporting was shown to be motivated by reasons related to knowledge, attitudes, and excuses. Ignorance (10/13), complacency (6/13), and lethargy (6/13) were the most frequent reasons for not reporting., Conclusion: This study highlighted the scarcity of research conducted with the aim of assessing ADR underreporting by patients. Knowledge, attitudes, and excuses were commonly observed in the decision to report ADRs. These motives are characteristics that can be changed; hence strategies must be designed to raise awareness, continually educate, and empower this population to change the paradigm of underreporting., (© 2023.

Mercury (Hg) is a global contaminant affecting aquatic ecosystems' health. Chronic exposure to Hg has shown that the normal development of zebrafish embryo-larvae is affected. However, the molecular mechanisms behind the toxicity of Hg on fish embryonic development are still poorly understood. This work aimed to investigate the effects of Hg exposure on zebrafish embryo-larvae using a combined approach at individual (mortality, embryo development and locomotor behavior) and biochemical (neurotoxicity and oxidative stress enzymatic activities and protein phosphatase expression) levels. The Fish Embryo Toxicity assay followed the Organization for Economic Cooperation and Development Guideline 236 and used a concentration range between 13 and 401 μg Hg/L. Lethal and developmental endpoints were examined at 24, 48, 72 and 96 hpf. Biochemical markers, including Acetylcholinesterase (AChE), Catalase (CAT), Glutathione Reductase (GR), and Glutathione-S-Transferase (GST) activities and, for the first time, the expression of the protein phosphatase 1 gamma (PP1γ) was assessed after 24, 48, 72 and 96 h of exposure to 10 and 100 μg Hg/L. The behavioral effects of a sublethal range of Hg (from 0.8 to 13 μg Hg/L) were assessed using an automated video tracking system at 120 hpf. Several developmental abnormalities on zebrafish embryos and larvae, including pericardial edema, spin and tail deformities and reduced rate of consumption of the yolk sac, were found after exposure to Hg (LC 50 at 96 hpf of 139 μg Hg/L) with EC 50 values for total malformations ranging from 22 to 264 μg Hg/L. After 96 hpf, no significant effects were observed in the CAT and GR activities. However, an increase in the GST activity in a concentration and time-dependent manner was found, denoting possible stress-related adaptation of zebrafish embryos to deleterious effects of Hg exposure. The AchE activity showed a response pattern in line with the behavioral responses. At the lowest concentration tested, no significant effects were found for the AChE activity, whereas a decrease in AChE activity was observed at 100 μg Hg/L, suggesting that exposure to Hg induced neurotoxic effects in zebrafish embryos which in turn may explain the lack of equilibrium found in this study (EC 50 at 96 hpf of 83 μg Hg/L). Moreover, a decrease in the PP1γ expression was found after 96 h of exposure to 10 and 100 μg Hg/L. Thus, we suggest that Hg may be an inhibitor of PP1γ in zebrafish embryos-larvae and thus, along with the alterations in the enzymatic activity of GST, explain some of the developmental malformations observed, as well as the lack of equilibrium. Hence, in this study, we propose the use of PP1 expression, in combination with apical and biochemical endpoints, as a precursor for assessing Hg's toxic mechanism on embryonic development., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Male infertility is a prevalent concern affecting couples worldwide. While genetic factors, hormonal imbalances, and reproductive system defects play significant roles, emerging evidence suggests that lifestyle choices also profoundly impact male fertility. This study aimed to explore the effects of several lifestyle factors, including tobacco and alcohol consumption, physical activity, and dietary habits, on semen quality parameters and molecular biomarkers. Thirty healthy male volunteers were recruited in the Urology service at Hospital Infante D. Pedro, Aveiro, Portugal. Participants completed lifestyle questionnaires and provided semen samples, which were analyzed according to the World Health Organization criteria by experienced technicians. We also analyzed the expression levels of antioxidant enzymes and heat-shock response-related proteins to explore the activation of signaling pathways involved in stress response within sperm cells. Our results revealed that tobacco consumption reduced semen volume and total sperm count. Although the changes in the percentage of total motility and normal morphology in the smokers' group did not reach statistical significance, a slight decrease was observed. Moreover, we identified for the first time a significant association between tobacco consumption and increased levels of heat shock protein 27 (HSP27) and phosphorylated HSP27 (p-HSP27) in sperm cells, indicating the potential detrimental effects of tobacco on the reproductive system. This study highlights that lifestyle factors reduce semen quality, possibly by inducing stress in sperm, raising awareness about the effects of these risk factors among populations at risk of male infertility.

Introduction: Differences in digital health literacy levels are associated with a lack of access to digital tools, usage patterns, and the ability to effectively use digital technologies. Although some studies have investigated the impact of sociodemographic factors on digital health literacy, a comprehensive evaluation of these factors has not been conducted. Therefore, this study sought to examine the sociodemographic determinants of digital health literacy by conducting a systematic review of the existing literature., Methods: A search of four databases was conducted. Data extraction included information on study characteristics, sociodemographic factors, and the digital health literacy scales used. Meta-analyses for age and sex were conducted using RStudio software with the metaphor package., Results: A total of 3922 articles were retrieved, of which 36 were included in this systematic review. Age had a negative effect on digital health literacy (B = -0.05, 95%CI [-0.06; -0.04]), particularly among older adults, whereas sex appeared to have no statistically significant influence among the included studies (B = - 0.17, 95%CI [-0.64; 0.30]). Educational level, higher income, and social support also appeared to have a positive influence on digital health literacy., Discussion: This review highlighted the importance of addressing the digital health literacy needs of underprivileged populations, including immigrants and individuals with low socioeconomic status. It also emphasizes the need for more research to better understand the influence of sociodemographic, economic, and cultural differences on digital health literacy., Conclusions: Overall, this review suggests digital health literacy is dependent on sociodemographic, economic, and cultural factors, which may require tailored interventions that consider these nuances., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Evidence of the effect of statins on patients with coronavirus disease (2019) COVID-19 is inconsistent. The aim of this study was to evaluate the association between chronic use of statins-both overall and by active ingredient-and severe outcomes of COVID-19 (risk of hospitalization and mortality), progression to severe outcomes, and susceptibility to the virus. We conducted a population-based case-control study with data from electronic records to assess the risk of (1) hospitalization: cases were patients admitted due to COVID-19 and controls were subjects without COVID-19; (2) mortality: cases were hospitalized patients who died due to COVID-19 and controls were subjects without COVID-19; (3) progression: cases were hospitalized COVID-19 subjects and controls were nonhospitalized COVID-19 patients; and (4) susceptibility: cases were patients with COVID-19 (both hospitalized and nonhospitalized) and controls were subjects without COVID-19. We collected data on 2821 hospitalized cases, 26 996 nonhospitalized cases, and 52 318 controls. Chronic use of atorvastatin was associated with a decreased risk of hospitalization (adjusted odds ratios [aOR] = 0.83; 95% confidence interval [CI]: 0.74-0.92) and mortality (aOR = 0.70; 95% CI: 0.53-0.93), attributable in part to a lower risk of susceptibility to the virus (aOR = 0.91; 95% CI: 0.86-0.96). Simvastatin was associated with a reduced risk of mortality (aOR = 0.59; 95% CI: 0.40-0.87). The wide degree of heterogeneity observed in the estimated odds ratios (ORs) of the different statins suggests that there is no class effect. The results of this real-world study suggest that chronic use of atorvastatin (and to a lesser degree, of simvastatin) is associated with a decrease in risk of severe COVID-19 outcomes., (© 2023 The Authors.

Purpose: To investigate the association between the use of antidepressants and the risk of upper gastrointestinal tract bleeding (UGIB)., Methods: A Case-control study was conducted in a Brazilian hospital complex. Cases were defined as patients with a diagnosis of UGIB and controls as patients admitted for reasons unrelated to gastrointestinal bleeding, gastric concerns, or complications associated with low-dose aspirin (LDA) or nonsteroidal anti-inflammatory drugs (NSAIDs) use. Sociodemographic and clinical data, comorbidities, drug therapy in use (long-term use and self-medication), and lifestyle habits were recorded through face-to-face interviews. Two groups were defined: use of antidepressants in general and use of antidepressants according to their affinity for serotonin transporters. The presence of synergism between the concomitant use of antidepressants and LDA or NSAIDs on the risk of UGIB was also explored., Findings: A total of 906 participants were recruited (200 in the case group and 706 in the control group). The use of antidepressants was not associated with the risk of UGIB (odds ratio [OR] = 1.503; 95% CI, 0.78-2.88) or the use of antidepressants with high affinity for serotonin receptors (OR = 1.983; 95% CI, 0.81-4.85). An increased risk of UGIB was observed in concomitant users of antidepressants and LDA (OR = 5.489; 95% CI, 1.60-18.81) or NSAIDs (OR = 18.286; 95% CI, 3.18-105.29). Despite the lack of significance, the use of antidepressants appears to be a positive modifier of UGIB risk in LDA and NSAID users., Implications: These findings indicate an increased risk of UGIB in concomitant users of antidepressants and LDA or NSAIDs, suggesting the need to monitor antidepressant users, especially those most likely to develop UGIB. In addition, further studies with larger sample sizes are needed to confirm these findings., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

The World Health Organization has proposed that a search be made for alternatives to vaccines for the prevention and treatment of COVID-19, with one such alternative being selective serotonin reuptake inhibitors (SSRIs). This study thus sought to assess: the impact of previous treatment with SSRI antidepressants on the severity of COVID-19 (risk of hospitalisation, admission to an intensive care unit [ICU], and mortality), its influence on susceptibility to SARS-CoV-2 and progression to severe COVID-19. We conducted a population-based multiple case-control study in a region in the north-west of Spain. Data were sourced from electronic health records. Adjusted odds ratios (aORs) and 95%CIs were calculated using multilevel logistic regression. We collected data from a total of 86,602 subjects: 3060 cases PCR+, 26,757 non-hospitalised cases PCR+ and 56,785 controls (without PCR+). Citalopram displayed a statistically significant decrease in the risk of hospitalisation (aOR=0.70; 95% CI 0.49-0.99, p = 0.049) and progression to severe COVID-19 (aOR=0.64; 95% CI 0.43-0.96, p = 0.032). Paroxetine was associated with a statistically significant decrease in risk of mortality (aOR=0.34; 95% CI 0.12 - 0.94, p = 0.039). No class effect was observed for SSRIs overall, nor was any other effect found for the remaining SSRIs. The results of this large-scale, real-world data study indicate that, citalopram, could be a candidate drug for being repurposed as preventive treatment aimed at reducing COVID-19 patients' risk of progressing to severe stages of the disease., Competing Interests: Conflicts of Interest The authors declare that they have no conflicts of interest., (Copyright © 2023 The Author(s).

Adverse drug reactions (ADRs) are responsible for almost 5% of hospital admissions, making it necessary to implement different pharmacovigilance strategies. The additional monitoring (AM) concept has been highlighted and intended to increase the number of suspected ADRs reported, namely in medicines with limited safety data. A prospective, descriptive study of active pharmacovigilance (AP) was conducted between 2019 and 2021 in the Local Health Unit of Matosinhos (LHUM) (Porto, Portugal). A model of AP for medicines under AM, namely oral antineoplastic agents, was designed. Follow-up consultations were performed, and adverse events (AEs) data were collected. The overall response to the treatment was evaluated through the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. A total of 52 patients were included in the study, and 14 antineoplastic drugs under AM were analyzed. Of the total number of patients included, only 29 developed at least one type of toxicity. Hematological disorders were the most reported suspected ADR. However, only four patients interrupted their treatment due to toxicity. After 12 months of treatment, most patients had disease progression, which was the main reason for therapy discontinuation. This AP model played an important role in the early detection of AEs and, consequently, contributed to better management of them. Increasing the number of suspected ADR reports is crucial for drugs with limited safety data.

Background: Dentist play an important role in misuse of antibiotics. Identification of the dental activities linked to the misuse of antibiotics is important for improving dentists' prescribing quality. The aim of the study was to quantify the magnitude of inappropriate antibiotic prescribing by dentists in Spain and identify the characteristics, knowledge and attitudes that influence prescribing quality., Material and Methods: We conducted a cross-sectional, questionnaire-based study on dentists in Spain, assessing prescribing quality (dependent variable) on the basis of their responses about the prescription of antibiotics in 14 clinical situations. As the independent variables, we assessed professional characteristics and attitudes (lack of knowledge, fear, complacency, scheduling problems, and economic benefit) measured on a Likert scale. Odds Ratios (OR) (95%CI) were calculated using logistic regression., Results: A total of 878 participants were included in the analysis. Half of all dentists displayed inappropriate antibiotic prescribing habits in more than 28.6% (10/14) of the clinical situations posed (interquartile range 57-79%). Prescribing quality increased when resistance was perceived as a public health problem (OR 0.88, 95% CI: 0.79-0.97), and decreased in response to fear (OR 1.12, 95% CI:1.07-1.18) or the pursuit of economic benefit (OR 1.07, 95% CI 1.01-1.14). Having over 30 years' experience (OR 4.58, 95% CI:1.80-12.48) and/or practising in the field of prosthodontics as opposed to endodontics (OR 2.65, 95% CI:1.26-5.71) were associated with worse prescribing quality., Conclusions: Antibiotics are the most commonly prescribed drugs in dentistry, and in many cases this prescription is inappropriate. Our findings shows that modifiable factors influence prescribing quality among dentists in Spain. These may be use for designing educational and training programmes for dentists., (© 2023.

Aging is associated with an increase in the prevalence of chronic diseases and polypharmacy, and with the prescription of potentially inappropriate medications (PIMs). This study aimed to analyze the variation in PIMs from hospital admission to discharge. A retrospective cohort study was conducted on inpatients of an internal medicine service. According to the Beers criteria, 80.7% of the patients had been prescribed at least one PIM at admission and 87.2% at discharge; metoclopramide was the most-prescribed PIM from admission to discharge, and acetylsalicylic acid was the most-deprescribed one. According to the STOPP criteria, 49.4% of patients had been prescribed at least one PIM at admission and 62.2% at discharge; quetiapine was the most-prescribed PIM from admission to discharge, and captopril was the most-deprescribed one. According to the EU(7)-PIM list, 51.3% of patients had been prescribed at least one PIM at admission and 70.3% at discharge, and bisacodyl was the most-prescribed PIM from admission to discharge and propranolol the most-deprescribed one. It was found that the number of PIMs at discharge was higher than at admission, suggesting the need to develop a guide with adapted criteria to be applied in an internal medicine service.

Antibiotic resistance is an issue of growing importance in the public health sphere. Medical interns are of great relevance when it comes to the source of this problem. This study therefore sought to ascertain which factors influence the management of antibiotic therapy by this population, in order to pinpoint the possible causes of misprescribing habits. We conducted a qualitative study based on focus group techniques, with groups consisting of medical interns from the Santiago de Compostela Clinical University Teaching Hospital. Our study identified factors which the participants considered to be determinants of antibiotic use and their relationship with the appearance of resistance. The single most repeated factor was the influence of the attending physician's judgement; other factors included a high healthcare burden or prescribing inertia. This stage is an opportunity to correct misprescribing habits, by implementing educational interventions aimed at modifying the identified factors.

Colchicine is one of the most widely studied and best-known anti-inflammatory treatments. This study aimed to assess the effect of colchicine on risk of hospitalization due to COVID-19; and its effect on susceptibility to and severity of the virus in patients with COVID-19. We carried out a population-based case-control study. The following groups were applied: (1) to assess risk of hospitalization, cases were patients with a positive PCR who were hospitalized due to COVID-19, and controls without a positive PCR; (2) to assess susceptibility to COVID-19, cases were patients with a positive PCR (hospitalized and non-hospitalized), and the same controls; (3) to determine potential severity, cases were subjects with COVID-19 hospitalized, and controls patients with COVID-19 nonhospitalised. Different electronic, linked, administrative health and clinical databases were used to extract data on sociodemographic variables, comorbidities, and medications dispensed. The study covered 3060 subjects with a positive PCR who were hospitalized, 26 757 with a positive PCR who were not hospitalized, and 56 785 healthy controls. After adjustment for sociodemographic variables, comorbidities and other treatments, colchicine did not modify risk of hospitalization due to COVID-19 (adjusted odd ratio [OR] 1.08 [95% confidence interval (CI) 0.76-1.53]), patients' susceptibility to contracting the disease (adjusted OR 1.12 (95% CI 0.91-1.37)) or the severity of the infection (adjusted OR 1.03 [95% CI 0.67-1.59]). Our results would neither support the prophylactic use of colchicine for prevention of the infection or hospitalization in any type of patient, nor justify the withdrawal of colchicine treatment due to a higher risk of contracting COVID-19., (© 2023 The Authors.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on everyday life, the environment, and health care services. A shift from in-person medical appointments to telemedicine was a main adjustment. Such changes can have repercussions on the control and management of chronic respiratory diseases, such as asthma. The available data suggest that there was an overall decrease in asthma-related morbidities during the first year of the pandemic. Therefore, the goal of this study was to quantify the effects of the pandemic on the prescribing of antiasthmatic treatments in outpatient care (public and private health care)., Methods: This before-after study used a time series approach based on data from monthly prescriptions of antiasthmatic drugs (anti-inflammatory drugs and bronchodilators) dated between April 2018 and March 2021. An interrupted time series (ITS) design was used for assessing changes in antiasthmatic prescribing patterns in the short and long terms after COVID-19 was recognized as a pandemic. The results are complemented with seasonal autoregressive integrated moving average (sARIMA) models., Findings: The ITS analysis showed a non-significant increase in antiasthmatic prescribing in the short term. In the long term, after the pandemic was declared, a statistically significant decrease was observed in the prescribing of antiasthmatics (in anti-inflammatory drugs and, more pronounced, in bronchodilators). In the sARIMA model, the mean monthly volume of antiasthmatic prescriptions was 18.1% lower than predicted. The numbers of months outside of the 95% CIs were different between anti-inflammatory drugs (1 month) and bronchodilators (7 months)., Implications: The prescribing of antiasthmatic drugs in the long term was significantly decreased with the COVID-19 pandemic, with a greater effect in the case of bronchodilators., Competing Interests: Declaration of Interest The authors have indicated that they have no conflicts of interest with regard to the content of this article., (Copyright © 2023.

Objective: The aim of this study is to develop and validate a novel clinical report form in the format of a structured interview to enable the characterization of the Portuguese population of the Baixo Vouga region with different subtypes of nodular thyroid pathologies (NTyPs)., Materials and Methods: A structured interview was developed and to the best of our knowledge, this is the first structured interview built and validated for that purpose in Portugal., Results: This structured interview enables the identification of possible correlations between each subtype of nodular lesions and sociodemographic data, consumption habits and lifestyle, endocrine history, and family predisposition., Conclusion: The novel structured interview will simultaneously, enable a detailed characterization of the group of patients with nodular thyroid lesions and will support future metabolomic studies.

Background: Semaglutide is a Glucagon-like peptide-1 receptor agonist used in the second-line treatment of poorly controlled type 2 diabetes and can be used in monotherapy or associated with other oral antidiabetics or even insulin, increasing the effectiveness of the treatment. This work aims to analyze the profile of adverse drug reactions reported for semaglutide in Eudravigilance., Research Design and Methods: Data on Individual Cases Safety Reports were obtained from the database of the centralized European spontaneous reporting system Eudravigilance by accessing www.adrreports.eu. (1 December 2021)., Results: It is possible to observe a high prevalence of gastrointestinal disorders (N = 3502, 53.2%). The most severe reported cases were primarily gastrointestinal disorders, metabolic, and nutritional disorders, eye disorders, renal and urinary disorders and cardiac disorders, with an evident higher prevalence of adverse gastrointestinal events both in oral and injectable dosage form (N = 133, 50.0% vs N = 588, 47.2%, respectively). Through a comparative analysis, semaglutide had a greater number of reported gastrointestinal adverse events compared to sitagliptin and empaglifozin (p < 0.00001)., Conclusions: Semaglutide has a good safety profile, however the definition of subgroups within the type 2 diabetes population who are particularly prone to develop serious adverse event when treated with GLP-1 RAs is crucial.

Background: Vaccination against COVID-19 has had a major impact over the course of the pandemic, leading to a reduced number of hospitalizations and deaths. However, the mass vaccination process has been accompanied by skepticism and hesitancy since its beginning. As health professionals and teachers are important public health actors who can strongly intervene to reduce vaccination hesitancy among their patients and students, respectively, this study aimed to assess their main perceptions towards COVID-19 vaccination., Methods: Two focus group sessions, one with health professionals and the other with teachers, were conducted according to the COREQ checklist. Qualitative data were analyzed through theoretical thematic analysis., Results: In general, none of the groups showed vaccine hesitancy, although both groups had concerns regarding the safety and efficacy of the vaccines. The main concerns of health professionals were mostly related to the long-term impact of the COVID-19 pandemic, while teachers were more worried about the lack of access to reliable information about the COVID-19 vaccination., Conclusions: It is plausible to conclude that it is imperative to provide clear and accurate information for the population in order to avoid vaccination hesitancy.

Since the authorization of the first COVID-19 vaccines in December 2020, multiple studies using real-world data (RWD) have been published to assess their effectiveness/safety profile. This systematic review aimed to characterize the methods and outcomes of studies using RWD for assessment of COVID-19 vaccines, four months after vaccine approval. MEDLINE and EMBASE were searched to identify published studies until 6 May 2021. Two independent researchers selected relevant publications and extracted data from included studies. The risk of bias was assessed using New-Castle Ottawa tools. After screening 1086 studies, 15 were included. Out of the 15 studies, 12 (80%) followed a cohort design, 8 (53%) were based on USA data, 7 (47%) assessed health care professionals, and 14 articles (93%) assessed the BNT162b2 vaccine. Data sources included institutional databases, electronic health records, and patient-generated data. The primary endpoint mainly described was SARS-CoV-2-infection. Hospitalization and mortality were assessed in 2 studies. For the comparability domain, six studies (40%) had a high risk of bias. A few months after the beginning of COVID-19 vaccination, Real-world Evidence (RWE) provided timely safety surveillance and comparative effectiveness with findings that showed similar findings to Randomized control trial (RCT). Most of the initiatives assessed BNT162b2 and were conducted in the USA and used healthcare workers' data.

Background: Vaccine hesitancy decreases adult vaccination coverage and has been recognized by WHO as a major health threat. Primary care physicians (PCP) play a key role in vaccination by giving vaccine counselling to their patients. The aim of this systematic review is to identify the knowledge, beliefs, attitudes and barriers (KBAB) associated with own vaccination and patient recommendation in primary care physicians., Methods: MEDLINE/PubMed, EMBASE and Cochrane Library databases were used to search and identify relevant studies based on their title and abstract. In the next step, the full text of each previously selected article was read for eligibility. Articles were selected by two independent reviewers and data extraction was performed using tables. The following information was extracted: methodological characteristics, demographic factors, professional characteristics, and intrinsic or extrinsic factors influencing vaccination or recommendation., Results: Our search yielded 41 eligible papers, data-sources, previous practices, belief in the effectiveness or safety of the vaccine, perceived risk, and trust in health authorities were all shown to be related to own vaccination and patient recommendation., Conclusion: Internet is the main source of information for PCP related to vaccine hesitancy. It is therefore essential to increase the presence and access to pro-vaccination content in this area. In addition, involving PCP in the establishment of vaccination recommendations could improve their credibility in the institutions. On the other hand, training in communication skills and establishing reminder systems could reflect higher vaccination coverage among their patients.

Multiple medication intake by older adults is considered a serious public health concern since it is associated with increased risk of adverse drug reactions and potentially inappropriate medication (PIM). This study described the top-10 prescribed active substances considering geographical distribution and PIM prescription in older adults. A cross-sectional ecological study using data on the active substances prescribed to people aged 65 years or older during 2020 was conducted. Information on active substances and the respective defined daily doses (DDD) stratified by age group, sex and region were collected from a Portuguese health administrative database. The average number of prescribed packages and DDD per 1000 inhabitants per day of top-10 active substances were assessed. This study included a total of 2,228,090 older adults (58% females). The furosemide and atorvastatin were the active substances with higher prescription rates (mean DDD/1000 inhabitants/day) in all ARS in both males and females, in comparison with the other top-10 active substances. Our results showed geographic differences in prescription, illustrated by more prescriptions in ARS North and Centre and fewer prescriptions in ARS Algarve. In females, two out of the 10 most prescribed active substances were PIM (benzodiazepines and opioids). Geographic disparities in PIM prescription across Portuguese regions were also observed. This study shows that drugs for the cardiovascular system were the active substances most prescribed to older adults. The prescription of benzodiazepines and opioids, classified as PIM, among females, alerts officials to the need of health policies to decrease inappropriate medication. The observed geographic differences in the 10 most prescribed active substances and in PIM prescription emphasized the importance of investing in medication optimization across the Portuguese regions.

Background: During the COVID-19 pandemic, social media became an important and easily accessible source of information to keep the population informed. In this study, we explored how Portuguese health entities used social media during the public health emergency caused by COVID-19 disease., Methods: A retrospective study on Portuguese public health entities' communication with the public using social media platforms was performed. Data were retrieved from Facebook, Instagram, and Twitter. All retrieved posts were analyzed, and the engagement of the public was calculated. A thematic analysis of all COVID-19-related posts was conducted., Results: The analysis of each social media platform revealed that during the COVID-19 pandemic, health entities reinforced their presence on social media platforms. The most published posts were related to "epidemiological context" and "encouragement to take actions" to avoid the spread of COVID-19. High engagement frames were not associated with the most frequently published posts., Conclusions: Although health entities have reinforced their presence on social media platforms, they do not take full advantage of these platforms to improve health literacy.

Antibiotic resistance remains a crucial global public health problem with excessive and inappropriate antibiotic use representing an important driver of this issue. Strategies to improve antibiotic prescription and dispensing are required in primary health care settings. The main purpose of this review is to identify and synthesize available evidence on the economic impact of educational interventions to reduce prescription and dispensing of antibiotics among primary health care professionals. Information about the clinical impact resulting from the implementation of interventions was also gathered. PubMed, Scopus, Web of Science and EMBASE were the scientific databases used to search and identify relevant studies. Of the thirty-three selected articles, most consisted of a simple intervention, such as a guideline implementation, while the others involved multifaceted interventions, and differed regarding study populations, designs and settings. Main findings were grouped either into clinical or cost outcomes. Twenty of the thirty-three articles included studies reporting a reduction in outcome costs, namely in antibiotic cost and associated prescription costs, in part due to an overall improvement in the appropriateness of antibiotic use. The findings of this study show that the implementation of educational interventions is a cost-effective strategy to reduce antibiotic prescription and dispensing among primary healthcare providers.

The emergence of antibiotic resistance (ABR) is one of the most serious public health threats worldwide. The inappropriate use of antibiotics is considered the main determinant for the increase and development of ABR, contributing to a greater risk of therapeutic ineffectiveness, particularly within primary care context. Therefore, this pilot study aims to raise awareness and promote an adequate antibiotic use among physicians, through the evaluation of the eHealthResp platform, a digital intervention composed by an online course and a mobile application, to aid in the management of respiratory tract infections. The global validation of the eHealthResp platform was carried out by 12 physicians who explored and performed a quantitative and qualitative evaluation of the contents of the online course and mobile app. The global evaluation of the analyzed parameters was very positive, with the highest median scores being attributed to adequacy, correction, format, and trust of the eHealthResp platform. The qualitative feedback enhanced the contents' relevance, clarity, and consolidation, as well as the effectiveness of the educational intervention against ABR. Overall, this study revealed that the eHealthResp may be regarded as an important e-health tool for the management of respiratory tract infections and improvement of antibiotic prescription practices among physicians.

The inadequate use of antibiotics led to the development of multi-resistant bacteria that are now causing millions of deaths worldwide. Since most antibiotics are prescribed/dispensed to treat respiratory tract infections, it is important to raise awareness among health professionals to optimize antibiotic use, especially within the primary care context. Thus, this pilot study aimed to evaluate pharmacists' feedback about the eHealthResp platform, composed by an online course and a mobile application (app) to help in the management of upper respiratory tract infections (URTIs). Ten community pharmacists were invited to participate in this study, exploring the contents of the eHealthResp platforms and answering a content validation questionnaire composed by eight qualitative and thirty-five quantitative questions about the online course and mobile app. The eHealthResp platform is a comprehensive, consistent, and high-quality e-learning tool. Median scores of 5.00 were attributed to the course contents' and clinical cases' adequacy and correction. Most qualitative feedback was about completeness and objectivity of the course, and its usefulness for clinical practice. This study showed that eHealthResp has great potential as an e-health tool for the management of URTIs' symptoms, which may ultimately aid in reducing inappropriate antibiotic use.

(1) Background: According to the World Health Organization (WHO), benzodiazepines (BZD) are considered essential medicines for the treatment of several mental disorders in older adults over 65 years old. However, the long-term use of BZD could present a harmful impact on this population, leading to cognitive deficits, drug dependence, falls, and fractures. This study aims to analyze trends of BZD prescription to Portuguese older adults in the primary care setting, and to analyze the change in the prescription rate of BZD over time, assessing the geographical variability in mainland Portugal. (2) Methods: A nationwide, retrospective ecological study was performed between January 2019 and December 2021 for BZD prescribing data reported in a national public database for all persons aged 65 and older in mainland Portugal (about 2.4 million). Trends of BZD by defined daily doses (DDD) and per 1000 older adults' inhabitants per day (DID) were analyzed. (3) Results: A total of 19 BZD were included in this study and more than 1 million BZD prescriptions were recorded in each year of this study period. BZD prescriptions were three times higher in females than in males. Alprazolam, lorazepam, diazepam, ethyl loflazepate, and bromazepam were the most prescribed BZD over the years, presenting the higher DDD and DID values. (4) Conclusions: Despite the DID value growth of several BZD, Portugal is now showing stable BZD prescriptions in older adults, between the years 2019 to 2021. More studies are needed to access if these results are a consequence of successful health programs or just a consequence of the pandemic context that we are facing, which limited older adults' clinical appointments.

Background: Portugal has among the highest rates of dependency among older adults in Europe. Older adults with aging-related comorbidities are prone to the use of potentially inappropriate medication (PIM)., Objective: The aim of this study was to analyze PIM prescriptions in older Portuguese adults, as well as the change rate of PIM prescriptions over time, and assess the geographical variability between the different regions of mainland Portugal., Methods: Using a national database, PIM prescriptions were analyzed for older adults (aged 65 years and older) between 2019 and 2021 from 2 perspectives: PIM-defined daily dose (DDD) frequency (%) and DDD per 1000 inhabitants per day (DID)., Results: Overall, mainland Portugal presented a PIM DDD frequency of 9.20%, which was relatively higher in Alentejo and Centro and lower in the North. Alprazolam, fluoxetine, and rivaroxaban were PIM with higher DDD frequency values. Over the years, the DID change rates for these three PIM were -3.80%, -14.86%, and +18.54%, respectively, depending on the geographic region. Alprazolam and fluoxetine were mostly prescribed to older women, whereas rivaroxaban was mostly prescribed to older men., Conclusions: These results emphasize the need to implement initiatives and interventions to decrease PIM prescriptions in older adults., (© 2022 The Author(s).)

Introduction: To contain the COVID-19 pandemic, higher vaccination rates are essential. However, as vaccine hesitancy is a reality, it is important to understand what drives health professionals to refuse getting vaccinated against COVID-19, who have been in the frontline of this pandemic since its beginning and may be key actors to improve vaccine coverage among their patients., Purpose: This study aims to assess the factors associated with vaccine hesitancy (VH) among health professionals (physicians, nurses, pharmacists and dentists)., Methods: A nationwide cross-sectional study was conducted through an online survey, with 890 Portuguese health professionals. A logistic regression analysis was used to determine the adjusted odds ratio (OR) of the independent variables (perceptions, knowledge and attitudes) per 1-point increase in the Likert scale and VH., Results: Complacency, communications, confidence and convenience were strongly associated with VH probability. Concerns about vaccines' efficacy (OR Physicians  = 8.33, 95% CI: 4.51-15.36) and safety (OR Nurses  = 11.07, 95% CI: 4.12-29.77) increase the risk of VH on all health professional groups. A reduction of VH probability is associated with higher risk perceptions of getting infected (1/OR Nurses  = 2.76, 95% CI: 1.52-5.02) and suffering complications (1/OR Nurses  = 33.72, 95% CI: 8.48-134.13), higher confidence in the effectiveness of COVID-19 vaccines (1/OR Dentists  = 12.29, 95% CI: 2.91-51.89), risk perception of getting infected if vaccinated (1/OR Physicians  = 14.92, 95% CI: 6.85-32.50), risk of suffering from complications after getting vaccinated, and higher trust levels on the information transmitted by competent authorities (1/OR Dentists  = 17.76, 95% CI: 3.83-82.22)., Conclusions: To reduce COVID-19 VH, which appears to be highly influenced by perceptions, knowledge and attitudes, it is essential to promote interventions directed to transforming these potentially modifiable determinants., (© 2022 Stichting European Society for Clinical Investigation Journal Foundation.
