RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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. The protocol of this systematic review can be found in PROSPERO under registration no. CRD42021253937.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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 (LC50 at 96 hpf of 139 µg Hg/L) with EC50 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 (EC50 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.

RESUMEN

INTRODUCTION: Underreporting is a major limitation of the voluntary reporting system of adverse drug reactions (ADRs). A 2009 systematic review showed the knowledge and attitudes of health professionals were strongly related with underreporting of ADRs. OBJECTIVE: Our aim was to update our previous systematic review to determine factors (sociodemographic, knowledge and attitudes) associated with the underreporting of ADRs by healthcare professionals. METHODS: We searched the MEDLINE and EMBASE databases for studies published between 2007 and 2021 that met the following inclusion criteria: (1) published in English, French, Portuguese or Spanish; (2) involving health professionals; and (3) the goal was to evaluate factors associated with underreporting of ADRs through spontaneous reporting. RESULTS: Overall, 65 papers were included. While health professional sociodemographic characteristics did not influence underreporting, knowledge and attitudes continue to show a significant effect: (1) ignorance (only serious ADRs need to be reported) in 86.2%; (2) lethargy (procrastination, lack of interest, and other excuses) in 84.6%; (3) complacency (the belief that only well tolerated drugs are allowed on the market) in 46.2%; (4) diffidence (fear of appearing ridiculous for reporting merely suspected ADRs) in 44.6%; and (5) insecurity (it is nearly impossible to determine whether or not a drug is responsible for a specific adverse reaction) in 33.8%, and the absence of feedback in 9.2%. In this review, the non-obligation to reporting and confidentiality emerge as new reasons for underreporting. CONCLUSIONS: Attitudes regarding the reporting of adverse reactions continue to be the main determinants of underreporting. Even though these are potentially modifiable factors through educational interventions, minimal changes have been observed since 2009.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.
