Factors associated with scientific production conditions among dental students from the Peruvian capital: an analysis under a multivariable regression model.

BACKGROUND: The purpose of scientific production is to synthesize and capture research for eventual publication. In Peru, scientific production at the undergraduate level is relatively limited. The purpose of this study was to identify the factors associated with scientific production conditions among dental students from the Peruvian capital. METHODS: This cross-sectional and analytical study evaluated 338 dental students from the Peruvian capital using a questionnaire composed of 15 questions on conditions for scientific production. Pearson's chi-square test and Fisher's exact test were used for bivariate analysis. To evaluate the influential variables, the adjusted Poisson regression model with robust variance using the adjusted prevalence ratio (APR) was employed. The significance level was p < 0.05. RESULTS: A total of 17.8% of the students carried out research studies, while 1.5% published scientific articles. Conditions for scientific production were considered unfavorable in 28.4% of the cases, while 50.6% were classified as somewhat favorable and 21% as favorable. Students who dedicated < 2 h and ≥ 2 h per week to research were 3.04 and 3.84 times more likely to have favourable conditions for scientific production, respectively, compared to those who had no time for it (APR = 3.04, 95% CI: 1.02-9.03 and APR = 3.84, 95% CI: 1.13-13.02; respectively). CONCLUSION: A minority of dental students reported favorable conditions for scientific production. On the other hand, students with more weekly time for research are more likely to have favourable conditions for scientific production compared to those with no time.

Effects of mixed nuts as part of a Brazilian Cardioprotective diet on LDL-cholesterol in adult patients after myocardial infarction: a multicenter randomized controlled clinical trial.

BACKGROUND: Nuts consumption is related to cardioprotective effects on primary cardiovascular prevention, but studies conducted in secondary prevention are small, scarce and controversial. The objective of this trial was to evaluate the effects of a regional and sustainable cardioprotective diet added or not with an affordable mixed nuts on cardiometabolic features in patients with previous myocardial infarction. METHODS: DICA-NUTS study is a national, multi-center, and superiority-parallel randomized clinical trial. Males and females over 40 years old diagnosed with previous myocardial infarction in the last 2 to 6 months were included. Patients were allocated into two groups: the Brazilian Cardioprotective diet (DICA Br) supplemented with 30 g/day of mixed nuts (10 g of peanuts; 10 g of cashew; 10 g of Brazil nuts) (intervention group, n = 193); or only DICA Br prescription (control group, n = 195). The primary outcome was low-density lipoprotein cholesterol means (in mg/dL) after 16 weeks. Secondary outcomes were other lipid biomarkers, glycemic and anthropometric data and diet quality. RESULTS: After adjustment for baseline values, participating study site, time since myocardial infarction and statin treatment regimen (high potency, moderate and low potency/no statins), no significant difference was found between the groups in low-density lipoprotein cholesterol concentrations (intervention-control difference: 3.48 mg/dL [-3.45 to 10.41], P = 0.32). Both groups improved their overall diet quality at the end of the study without differences between them after 16 weeks (intervention-control difference: 1.05 (-0.9 to 2.99); P = 0.29). Other lipids, glycemic profile and anthropometrics were also not different between study groups at the end of the study. CONCLUSION: Adding 30 g/day of mixed nuts to the DICA Br for 16 weeks did not change lipid, glycemic and anthropometric features in the post-myocardial infarction setting. TRIAL REGISTRATION: This study is registered on ClinicalTrials.gov website under number NCT03728127 and its World Health Organization Universal Trial Number (WHO-UTN) is U1111-1259-8105.

A total of 3,965 contributing authors made 6,081 author appearances. In terms of total citations per country, Mexican authors received a total of 7,087 citations, with an average article citation of 8.76 per author. CONCLUSION: This bibliometric analysis highlights impactful research contributions to corneal and ocular surface research from Mexican authors, identifies influential authors and institutions, and also emphasizes the need for increased interaction in the international arena.

Improvement of post-periodontitis-therapy inflammatory state in diabetics: a meta-analysis of randomized controlled trials.

OBJECTIVES: This systematic review aimed to evaluate the impact of periodontal therapy on systemic biomarkers of inflammation and oxidative stress in patients with type 2 diabetes mellitus (T2DM) and periodontitis. MATERIALS AND METHODS: An electronic search without restriction on dates or languages was performed in six electronic databases, protocol records and other sources until May 2024. To develop the search strategy, clinical question was formulated using the PICOD method. Eligibility criteria included randomized controlled trials on the effects of periodontitis-therapy on the inflammatory parameters of T2DM patients. Risk of bias and certainty of evidence were assessed by RoB2 and GRADE tools, respectively. The review protocol was registered in PROSPERO platform (CRD42020206295). RESULTS: Of 1,062 records screened, the authors determined that 14 studies enrolling 1223 participants proved eligible. Moderate-quality evidence suggested a positive effect of periodontitis-therapy on serum levels of c-reactive protein [0.39 (CI95%: 0.27-0.5)], even without the use of antibiotics [0.34 (CI95%: 0.22-0.46)], in T2DM patients. The significant reduction in C-reactive protein (CRP) among smokers in favor of periodontitis-therapy was greatest at six months of follow-up. CONCLUSIONS: Non-surgical periodontal therapy improved short-term biomarkers of systemic inflammation in T2DM patients, with moderate evidence of improvement in serum levels of high sensitivity-CRP. CLINICAL RELEVANCE: Systemic inflammation in T2DM patients can be reduced after non-surgical periodontal therapy, which also has the potential to reduce the risk of other important systemic outcomes, such as cardiovascular disease.

Unveiling the ethical void: Bias in reference citations and its academic ramifications.

Citation bias receives scant attention in discussions of ethics. However, inaccurate citation may lead to significant distortions in scientific understanding. Although ethnical and gender citation disparities have been proposed as critical aspects, there are other contributors to citation distortions, like region-based citation bias, that, although less recognized within the scientific community, are equally important. While the foundations of scientific citation include acknowledging pioneers, giving credit to related work, and providing background reading, other more subjective or even questionable criteria are often used when constructing a reference lists. Here, we discuss the potential causes and ethical concerns of citation bias, emphasizing the role of international- or region-based citation bias as one of the most harmful aspects of this ethical breach. We argue that the international scientific community should be aware of this problem and recognize its consequences, which include hindering the accurate dissemination of science, marginalizing underrepresented voices in academia, and impeding scientific progress. We advocate that scientists should compile their reference lists with the same seriousness and integrity they apply to all other aspects of their research.

[Predatory journals: What are they and how to avoid them?] / Las revistas depredadoras: ¿qué son y cómo evitarlas?

Currently, a large number of predatory journals have proliferated. Their purpose is to obtain fraudulent profits by promising the rapid publication of scientific works, without fulfilling the services of quality review. These publishers have managed to copy the models of open access journals, which is why they are increasingly difficult to identify, coupled with the fact that many of them have opened spaces in the most important indexes of scientific journals, such as Medline, Web of Science (WoS), Scopus, Embase, among others. These publishers cheat not only the authors of the research they intend to publish but also the readers and general public with publications that have not been reviewed and evaluated properly by a system of peers or academic experts. Therefore, the aim of this work is to make known some of the most common practices of predatory journals, so that anyone interested in the editorial process, whether as an author, editor or reader, has the elements to identify these fraudulent journals, and this bad practice in the editorial process.

Actualmente han proliferado una gran cantidad de revistas depredadoras, cuyo fin es obtener ganancias fraudulentas mediante la promesa de la publicación rápida de trabajos científicos, sin cumplir con los servicios de una revisión de calidad. Estas editoriales han logrado copiar los modelos de las revistas con acceso abierto, por lo que cada vez son más difíciles de identificar, aunado a que muchas de ellas se han abierto espacios en los índices más importantes de las revistas científicas, como Medline, Web of Science (WoS), Scopus, Embase, entre otros. Estas editoriales defraudan no solo a los autores de las investigaciones que intentan publicar sino también a los lectores y al público en general con publicaciones que no han sido debidamente revisadas y evaluadas por un sistema de pares o expertos académicos. Por lo tanto, el objetivo de este trabajo es dar a conocer algunas de las prácticas más comunes de las revistas depredadoras para que toda persona interesada en el proceso editorial, ya sea como autor, editor o lector, tenga los elementos para identificar estas revistas fraudulentas y esta mala práctica en el proceso editorial.

Problem-Based Learning in Medical Education: A Global Research Landscape of the Last Ten Years (2013-2022).

Background: Problem-based learning (PBL) constructs a curriculum that merges theory and practice by employing clinical scenarios or real-world problems. Originally designed for the pre-clinical phase of undergraduate medicine, PBL has since been integrated into diverse aspects of medical education. Therefore, this study aims to map the global scientific landscape related to PBL in medical education in the last ten years. Methods: We combined bibliometrics and network analysis to analyze the metadata of related research articles published between 2013 and 2022 and indexed in the Web of Science Core Collection. Results: Our results show an annual publication rate of 9.42%. The two main journals disseminating research on this subject are BMC Medical Education and Medical Teacher. Education & Educational Research and Health Care Sciences & Services are the two most frequent research areas, and also the two most central nodes of the related network. The USA and China are the most publishing countries, while the Netherlands and Canada are the most collaborative. The Maastricht University holds the position of most publishing and collaborative research organization. The University of California ranks second in publications, while the University of Toronto is the second most central research organization. Conclusions: Our study provides an overview of the last ten years of publications related to PBL and medical education, and we hope it can be of interest to educators, researchers, and students involved with this subject. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-024-02003-1.

Effect of Nuts on Anthropometric and Glycemic Indexes and Blood Pressure in Secondary Cardiovascular Prevention: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

CONTEXT: Nut-enriched diets have a positive impact on cardiovascular risk factors, such as body mass, blood pressure, and fasting blood glucose. However, studies in individuals undergoing secondary cardiovascular prevention show controversial results. OBJECTIVE: This systematic review with meta-analysis assessed the effect of nut supplementation on anthropometric, glycemic, and blood pressure indices in patients with atherosclerotic cardiovascular disease, as well as the frequency of adverse events. DATA SOURCES: Six databases were used for the search-PubMed, Cochrane Library, EMBASE, BVS (Biblioteca Virtual da Saude), Web of Science, and ClinicalTrials.gov-until February 2023, with no language restrictions. DATA EXTRACTION: The Cochrane Handbook for Systematic Reviews of Interventions methodology and the PICOS (Population, Intervention, Comparison, Outcome, Setting/design) strategy were used. Seven independent reviewers were involved in data extraction and resolution of disagreements. Certainty of the evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. DATA ANALYSIS: From 5187 records identified, 6 publications containing data referring to 5 randomized clinical trials (n = 436) were included in the final analyses. The nuts evaluated were almonds, pecans, Brazil nuts, and mixed nuts, with portions that varied between 5 g and 85 g (median: 30 g/day). The intervention period varied between 6 and 12 weeks. The nuts had no effect on fasting glucose and anthropometric indices, although the certainty of the evidence for most of these outcomes was low or very low. They also had no effect on systolic (mean difference [MD]: -1.16 mmHg [95% CI, -5.68 to 3.35], I2 = 0%-moderate certainty of evidence) or diastolic (MD: 0.10 mmHg [95% CI, -2.30 to 2.51], I2 = 0%-high certainty of evidence) blood pressure. It was not possible to aggregate data on adverse events. CONCLUSION: Nut supplementation had no effect on blood pressure, fasting glucose, or anthropometric profile in the context of atherosclerotic cardiovascular disease. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42020163456.

[Predatory journals in Orthopedics and Traumatology]. / Revistas depredadoras en Ortopedia y Traumatología.

Predatory journals are distinguished from legitimate journals by their lack of adequate reviews and editorial processes, compromising the quality of published content. These journals do not conduct peer reviews or detect plagiarism, and accept manuscripts without requiring substantial modifications. Their near 100% acceptance rate is driven by profit motives, regardless of the content they publish. While they boast a prestigious editorial board composed of renowned researchers, in most cases, it is a facade aimed at impressing and attracting investigators. Furthermore, these journals lack appropriate ethical practices and are non-transparent in their editorial processes. Predatory journals have impacted multiple disciplines, including Orthopedics and Traumatology, and their presence remains unknown to many researchers, making them unwitting victims. Their strategy involves soliciting articles via email from authors who have published in legitimate journals, promising quick, easy, and inexpensive publication. The implications and negative consequences of predatory journals on the scientific community and researchers are numerous. The purpose of this work is to provide general information about these journals, specifically in the field of Orthopedics and Traumatology, offering guidelines to identify and avoid them, so that authors can make informed decisions when publishing their manuscripts and avoid falling into the hands of predatory journals or publishers.

Las revistas depredadoras se diferencian de las revistas legítimas por su falta de adecuadas revisiones y procesos editoriales, lo que compromete la calidad del contenido publicado. Estas revistas no llevan a cabo revisiones por pares ni realizan acciones que detecten y prevengan el plagio y aceptan manuscritos sin exigir modificaciones sustanciales. Su tasa de aceptación cercana al 100% se debe a su enfoque lucrativo, sin importarles el contenido que publican. Aunque presumen tener un comité editorial compuesto por investigadores destacados, en la mayoría de los casos es una simulación destinada a impresionar y atraer a los investigadores. Además, estas revistas carecen de prácticas éticas adecuadas y no son transparentes en sus procesos editoriales. Las revistas depredadoras han afectado a múltiples disciplinas, incluida la Ortopedia y Traumatología y su presencia es aún desconocida para muchos investigadores, lo que los convierte en víctimas sin saberlo. Su estrategia consiste en solicitar artículos por correo electrónico a autores que han publicado en revistas legítimas, prometiendo una publicación rápida, sencilla y económica. Las implicaciones y consecuencias negativas de las revistas depredadoras en la comunidad científica y los investigadores son numerosas. El propósito de este trabajo es proporcionar información general sobre estas revistas y específicamente en el campo de la Ortopedia y Traumatología, brindando pautas para identificarlas y evitarlas, para que los autores puedan tomar decisiones informadas al publicar sus manuscritos y evitar caer en manos de revistas o editoriales depredadoras.

Do statins decrease testosterone in men? Systematic review and meta-analysis

ABSTRACT Purpose: Statins are one of the most prescribed classes of drugs worldwide to treat hypercholesterolemia and dyslipidemia. By lowering the level of cholesterol, the use of statin could cause a reduction in testosterone levels. The objective was to evaluate whether the continued use of statins in patients with hypercholesterolemia causes a deficiency in testosterone and other sex hormones. Materials and Methods: Systematic Review with Meta-analysis, performed in Embase, Medline and Cochrane databases, until May 2023; PROSPERO CRD42021270424protocol. Selection performed by two independent authors with subsequent conference in stages. Methodology based on PRISMA statement. There were selected comparative studies, prospective cohorts (CP), randomized clinical trials (RCT) and cross-sectional studies (CSS) with comparison of testosterone levels before and after statin administration and between groups. Bias analysis were evaluated with Cochrane Tool, The Newcastle-Ottawa Scale (NOS), and using the Assess the Quality of Cross-sectional studies (AXIS) tool. Results: There were found on MedLine, Embase and Cochrane, after selected comparative studies, 10CP and 6RCT and 6CSS for the meta-analysis. In the Forrest plot with 6CSS, a correlation between patients with continuous use of statins and a reduction in total testosterone was evidenced with a statistically significant reduction of 55.02ng/dL (95%CI=[39.40,70.64],I²=91%,p<0.00001). In the analysis with 5RCT, a reduction in the mean total testosterone in patients who started continuous statin use was evidenced, with a statistical significance of 13.12ng/dL (95%CI=[1.16,25.08],I²=0%,p=0.03). Furthermore, the analysis of all prospective studies with 15 articles showed a statistically significant reduction in the mean total testosterone of 9.11 ng/dL (95%CI=[0.16,18.06],I²=37%,p=0.04). A reduction in total testosterone has been shown in most studies and in its accumulated analysis after statin use. However, this decrease was not enough to reach levels below normal. Conclusion: Statins use causes a decrease in total testosterone, not enough to cause a drop below the normal range and also determines increase in FSH levels. No differences were found in LH, Estradiol, SHBG and Free Testosterone analysis.

The effectiveness of parasacral transcutaneous electrical nerve stimulation in the treatment of monosymptomatic enuresis in children and adolescents: a systematic review

ABSTRACT Background: Parasacral Transcutaneous Electrical Nerve Stimulation (PTENS) is a treatment used in enuresis refractory to first-line treatment. This review aimed to evaluate the effectiveness of PTENS in treating monosymptomatic enuresis (MNE) in children and adolescents. Methods: The study followed the Preferred Reporting Items for Systematic (PRISMA) guidelines. The search was carried out in the following databases: MEDLINE (via PubMed), Web of Science, SCOPUS, Central Cochrane Library and Physiotherapy Evidence Database (PEDro). The selected studies were randomized clinical trials (RCTs). The "Risk of Bias tool for randomized trials" and the "Risk of Bias VISualization" were used to analyze the risk of bias. Results: Of the 624 studies selected, four RCTs were eligible. Three included 146 children and adolescents aged between six and 16.3 years and used similar PTENS protocols with a frequency of 10 Hz, pulse duration of 700 µs and 20 minutes three times/week. One study enrolled 52 patients aged seven to 14 years used PTENS at home, with a pulse duration of 200 µs and 20 to 60 minutes twice/day. Risk of bias was observed in three studies due to results' randomization and measurement. Two studies showed a partial response with a reduction in wet nights, one a complete response in 27% of patients, and one showed no improvement. Conclusion: PTENS reduces wet nights' frequency but does not cure them, except in 27% of patients in one study. Limited RCTs and data heterogeneity are limitations.

¿Ensayos clínicos de superioridad, equivalencia o no inferioridad? / ¿Clinical trials of superiority, non-inferiority or equivalence?

La eficacia de una nueva intervención se establece generalmente a través de ensayos clínicos (EC) con asignación aleatoria (AA). Sin embargo, entre otros tantos desafíos metodológicos, el especificar la hipótesis de un EC con AA, sigue siendo un problema complejo de resolver para los investigadores clínicos. En este manuscrito discutimos las características de tres variantes de los EC con AA: EC de superioridad (ECS), EC de no-inferioridad (ECNI), y EC de equivalencia (ECE). Estos tres tipos de EC tienen supuestos diferentes sobre los efectos de una intervención, por lo que plantear hipótesis y definir objetivos requiere conocer algunos supuestos subyacentes a estos EC, incluso hasta elementos relacionados con la estimación del tamaño de muestra para cada cual. El objetivo de este manuscrito fue describir las diferencias metodológicas entre ECS, ECNI y ECE.

Efficacy and effectivity of new interventions are generally established through randomized clinical trials (RCTs). However, among many other methodological challenges, specifying the hypothesis of a RCT remains complex problem for clinical researchers. In this manuscript we discuss the characteristics of three variants of RCTs: superiority RCT (SRCT), non-inferiority RCT (NIRCT), and equivalence RCT (ERCT). These three types of RCT have different assumptions about the effects of an intervention, so setting hypotheses and defining objectives requires knowing some assumptions underlying these RCTs, including elements related to the estimation of the sample size for each one. The aim of this manuscript was to describe methodological differences between SRCT, NIRCT and ERCT.

A review of age estimation methods in non-avian reptiles by growth marks in hard tissues.

Age and growth-related data are basic biological parameters, essential in population ecology, evolution, and conservation biology. There is a growing body of published information on reptile demography derived from sclerochronology, a technique based on counting the growth layers deposited in bones (skeletochronology) and other hard body structures. Since the data are not always easily available, we compiled the existing published data, described the current status of knowledge, synthetized the conclusions of disparate studies, and identified patterns of research and information gaps, prioritizing the needs for future research. Our database includes the results of 468 published studies covering 236 reptile species from 41 families. These represent less than 2% of the total number of known extant species. Turtles and crocodiles are proportionally better studied, while snakes are the least examined group. The distribution of the research does not reflect conservation needs; we found an important geographic bias, with an overrepresentation of Northern temperate species. Only 23% of the studies checked the assumption of periodicity of growth marks deposition, and the method was found to be reliable or adequate in 79% of the cases. Overall, the data obtained through sclerochronology can be considered robust, especially if validation methods are employed, since the general goal is to characterize population parameters, trends, and dynamics, rather than determining the exact age of any specimen in particular.

Comparing Balloon Dilation to Non-Balloon Dilation for Access in Ultrasound-Guided Percutaneous Nephrolithotomy: A Systematic Review and Meta-Analysis

ABSTRACT Purpose: This study aims to evaluate the safety and efficacy of ultrasound-guided balloon dilation compared to non-balloon dilation for percutaneous nephrolithotomy (PCNL). Materials and methods: A systematic review and meta-analysis were conducted by searching PubMed, EMBASE, and the Cochrane Library. Results were filtered using predefined inclusion and exclusion criteria as described and meta-analysis was performed using Review Manager 5.4 software. Results: A total of six studies involving 1189 patients who underwent PCNL were included. The meta-analysis results demonstrated that compared to non-balloon dilation, balloon dilation was associated with reduced haemoglobin drop [mean difference (MD) = -0.26, 95% CI = -0.40 ~ -0.12, P = 0.0002], decreased transfusion rate [odds ratio (OR) = 0.47, 95% CI = 0.24 ~ 0.92, P = 0.03], shorter tract establishment time (MD = -1.30, 95% CI = -1.87 ~ -0.72, P < 0.0001) and shorter operation time (MD = -5.23, 95% CI = -10.19 ~ -0.27, P = 0.04). Conclusions: Overall, ultrasound-guided balloon dilatation offered several advantages in PCNL procedures. It facilitated faster access establishment, as evidenced by shorter access creation time. Additionally, it reduced the risk of kidney injury by minimizing postoperative haemoglobin drop and decreasing the need for transfusions. Moreover, it enhanced the efficiency of surgery by reducing the operation time. However, it is important to note that the quality of some included studies was subpar, as they did not adequately control for confounding factors that may affect the outcomes. Therefore, further research is necessary to validate and strengthen these findings.

Effect of aquatic exercise programs according to the International Classification of Functionality, Disability and Health domains in individuals with Parkinson's disease: a systematic review and meta-analysis with GRADE quality assessment.

PURPOSE: To investigate the effects of aquatic exercise programs (AEP) in body structure and function, activity, and participation outcomes in individuals with Parkinson's disease (PD) with mild to moderate disability levels. METHODS: Six databases were searched from inception until November 2022. Randomized clinical trials that used AEP alone, AEP combined and/or compared two types of AEP were included. The quality of evidence was assessed by the GRADE approach and the standardized mean differences (SMD) were calculated the meta-analysis. RESULTS: Twelve studies (n = 380) were included. AEP alone was superior to active control in improving body structure and function outcome: postural balance (low evidence, SMD = 0.47, p = 0.02). No statistically significant differences were found for the other body structure and function outcomes: lower limb muscle strength (p = 0.14) and depressive symptoms (p = 0.79), activity outcomes: mobility (p = 0.32) and participation outcomes: quality of life (p = 0.05). AEP combined showed no statistically significant difference for the outcomes of body structure and function: postural balance (p = 0.11) and activity: mobility (p = 0.21) when compared to active control. CONCLUSION: AEP showed positive effects on body structure and function outcome (postural balance) in individuals with PD with mild to moderate disability levels while, no significant improvements were noticed for activity and participation outcomes.IMPLICATIONS FOR REHABILITATIONOur findings indicate that aquatic exercise programs (AEP) lead to significant improvements on body structure and function (i.e., postural balance) in individuals with Parkinson's disease (PD).The AEP evaluated in this study implemented postural balance, gait, single and double training, as well as aerobic exercises, trunk mobility exercises, and Ai Chi.The average duration, frequency, and total time implemented were 50 minutes, three times a week, for seven weeks, respectively.Considering the potential benefits identified in this study, AEP can be recommended as an adjunct treatment strategy for individuals with PD.Additionally, the use of the International Classification of Functionality, Disability and Health on the development of rehabilitation treatment plans is advised.

Enhancing understanding of SARS-CoV-2 infection among individuals with Down syndrome: An integrative review

ABSTRACT BACKGROUND: Down syndrome (DS) is a non-rare genetic condition that affects approximately 1 in every 800 live births worldwide. Further, it is associated with comorbidities, anatomical alterations of the respiratory tract, and immunological dysfunctions that make individuals more susceptible to respiratory infections. OBJECTIVE: To systematize the current scientific knowledge about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among individuals with DS. DESIGN AND SETTING: This integrative review was conducted at the Universidade Federal de São Carlos, São Paulo, Brazil. METHODS: This review was conducted in the following databases: the Virtual Health Library (Biblioteca Virtual em Saúde, BVS), PubMed, and Web of Science, using MeSH descriptors. The search included English or Portuguese studies published between January 1, 2020, and October 14, 2022. RESULTS: A total of 55 articles from 24 countries were selected, comprising 21 case-control or cohort studies, 23 case reports or series, and 11 narrative reviews or opinion studies. The articles were grouped into five categories: previous comorbidities, coronavirus disease 2019 (COVID-19) clinical features and evolution, cytokine storm and interleukins, living in institutions as a risk factor, and behavioral actions as a protective factor against SARS-CoV-2 infection. CONCLUSION: Individuals with DS are more susceptible to COVID-19 infection due to variables such as previous comorbidities, immunological factors, and their habitable environments. These aspects confer a higher risk of infection and an unfavorable clinical course. The precise pathways involved in the pathophysiology of COVID-19 in individuals with DS are not clear, thus requiring further studies. SYSTEMATIC REVIEW REGISTRATION: The Open Science Framework registered the research protocol (https://osf.io/jyb97/).
