RESUMO

Genetic defects affecting steroid biosynthesis cause cortisol deficiency and differences of sex development; among them recessive mutations in the steroidogenic enzymes CYP11A1 and CYP11B, whose function is supported by reducing equivalents donated by ferredoxin reductase (FDXR) and ferredoxin. So far, mutations in the mitochondrial flavoprotein FDXR have been associated with a progressive neuropathic mitochondriopathy named FDXR-Related Mitochondriopathy (FRM), but cortisol insufficiency has not been documented. However, FRM patients often experience worsening or demise following stress associated with infections. We investigated two female FRM patients carrying the novel homozygous FDXR mutation p.G437R with ambiguous genitalia at birth and sudden death in the first year of life; they presented with cortisol deficiency and androgen excess compatible with 11-hydroxylase deficiency. In addition, steroidogenic FDXR-variant cell lines reprogrammed from three FRM patients' fibroblasts displayed deficient mineralocorticoid and glucocorticoid production. Finally, Fdxr-mutant mice allelic to the severe p.R386W human variant, showed reduced progesterone and corticosterone production. Therefore, our comprehensive studies show that human FDXR variants may cause compensated, but possibly life-threatening adrenocortical insufficiency in stress by affecting adrenal glucocorticoid and mineralocorticoid synthesis through direct enzyme inhibition, most likely in combination with disturbed mitochondrial redox balance.

RESUMO

OBJECTIVES: Autoantibodies targeting intracellular proteins are common in various autoimmune diseases. In the context of myositis, the pathologic significance of these autoantibodies has been questioned due to the assumption that autoantibodies cannot enter living muscle cells. This study aims to investigate the validity of this assumption. METHODS: Confocal immunofluorescence microscopy was employed to localise antibodies and other proteins of interest in myositis muscle biopsies. Bulk RNA sequencing was used to examine the transcriptomic profiles of 669 samples, including those from patients with myositis, disease controls and healthy controls. Additionally, antibodies from myositis patients were introduced into cultured myoblasts through electroporation, and their transcriptomic profiles were analysed using RNA sequencing. RESULTS: In patients with myositis autoantibodies, antibodies accumulated inside myofibres in the same subcellular compartment as the autoantigen. Bulk RNA sequencing revealed that muscle biopsies from patients with autoantibodies targeting transcriptional regulators exhibited transcriptomic patterns consistent with dysfunction of the autoantigen. For instance, in muscle biopsies from patients with anti-PM/Scl autoantibodies recognising components of the nuclear RNA exosome complex, an accumulation of divergent transcripts and long non-coding RNAs was observed; these RNA forms are typically degraded by the nuclear RNA exosome complex. Introducing patient antibodies into cultured muscle cells recapitulated the transcriptomic effects observed in human disease. Further supporting evidence suggested that myositis autoantibodies recognising other autoantigens may also disrupt the function of their targets. CONCLUSIONS: This study demonstrates that, in myositis, autoantibodies are internalised into living cells, causing biological effects consistent with the disrupted function of their autoantigen.

RESUMO

BACKGROUND: Coronary heart disease is one of the leading causes of mortality worldwide. Secondary prevention is essential, as it reduces the risk of further coronary events. Mobile health (mHealth) technology could become a useful tool to improve lifestyles. OBJECTIVE: This study aimed to evaluate the effect of an mHealth intervention on people with coronary heart disease who received percutaneous coronary intervention. Improvements in lifestyle regarding diet, physical activity, and smoking; level of knowledge of a healthy lifestyle and the control of cardiovascular risk factors (CVRFs); and therapeutic adherence and quality of life were analyzed. METHODS: This was a randomized controlled trial with a parallel group design assigned 1:1 to either an intervention involving a smartphone app (mHealth group) or to standard health care (control group). The app was used for setting aims, the self-monitoring of lifestyle and CVRFs using measurements and records, educating people with access to information on their screens about healthy lifestyles and adhering to treatment, and giving motivation through feedback about achievements and aspects to improve. Both groups were assessed after 9 months. The primary outcome variables were adherence to the Mediterranean diet, frequency of food consumed, patient-reported physical activity, smoking, knowledge of healthy lifestyles and the control of CVRFs, adherence to treatment, quality of life, well-being, and satisfaction. RESULTS: The study analyzed 128 patients, 67 in the mHealth group and 61 in the control group; most were male (92/128, 71.9%), with a mean age of 59.49 (SD 8.97) years. Significant improvements were observed in the mHealth group compared with the control group regarding adherence to the Mediterranean diet (mean 11.83, SD 1.74 points vs mean 10.14, SD 2.02 points; P<.001), frequency of food consumption, patient-reported physical activity (mean 619.14, SD 318.21 min/week vs mean 471.70, SD 261.43 min/week; P=.007), giving up smoking (25/67, 75% vs 11/61, 42%; P=.01), level of knowledge of healthy lifestyles and the control of CVRFs (mean 118.70, SD 2.65 points vs mean 111.25, SD 9.05 points; P<.001), and the physical component of the quality of life 12-item Short Form survey (SF-12; mean 45.80, SD 10.79 points vs mean 41.40, SD 10.78 points; P=.02). Overall satisfaction was higher in the mHealth group (mean 48.22, SD 3.89 vs mean 46.00, SD 4.82 points; P=.002) and app satisfaction and usability were high (mean 44.38, SD 6.18 out of 50 points and mean 95.22, SD 7.37 out of 100). CONCLUSIONS: The EVITE app was effective in improving the lifestyle of patients in terms of adherence to the Mediterranean diet, frequency of healthy food consumption, physical activity, giving up smoking, knowledge of healthy lifestyles and controlling CVRFs, quality of life, and overall satisfaction. The app satisfaction and usability were excellent. TRIAL REGISTRATION: Clinicaltrials.gov NCT04118504; https://clinicaltrials.gov/study/NCT04118504.

RESUMO

Biomass-derived oligo- and polysaccharides may act as elicitors, i.e., bioactive molecules that trigger plant immune responses. This is particularly important to increase the resistance of plants to abiotic and biotic stresses. In this study, cellulose nanofibrils (CNF) gels were obtained by TEMPO-mediated oxidation of unbleached and bleached kraft pulps. The molecular structures were characterized with ESI and MALDI MS. Analysis of the fine sequences was achieved by MS and MS/MS of the water-soluble oligosaccharides obtained by acid hydrolysis of the CNF gels. The analysis revealed the presence of two families: one corresponding to homoglucuronic acid sequences and the other composed by alternating glucose and glucuronic acid units. The CNF gels, alone or with the addition of the water-soluble oligosaccharides, were tested on Chili pepper (Capsicum annuum). Based on the characterization of the gene expression with Next Generation Sequencing (NGS) of the C. annuum's total messenger RNA, the differences in growth of the C. annuum seeds correlated well with the downregulation of the pathways regulating photosynthesis. A downregulation of the response to abiotic factors was detected, suggesting that these gels would improve the resistance of the C. annuum plants to abiotic stress due to, e.g., water deprivation and cold temperatures.

RESUMO

BACKGROUND: Microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) are the two major antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). OBJECTIVES: To characterize a homogenous AAV cohort and to assess the impact of clinicopathological profiles and ANCA serotypes on clinical presentation and prognosis. Clinical differences in GPA patients according to ANCA serotype and the diagnostic yield for vasculitis of biopsies in different territories were also investigated. RESULTS: This retrospective study (2000-2021) included 152 patients with AAV (77 MPA/75 GPA). MPA patients (96.1% myeloperoxidase [MPO]-ANCA and 2.6% proteinase 3 [PR3]-ANCA) presented more often with weight loss, myalgia, renal involvement, interstitial lung disease (ILD), cutaneous purpura, and peripheral nerve involvement. Patients with GPA (44% PR3-ANCA, 33.3% MPO, and 22.7% negative/atypical ANCA) presented more commonly with ear, nose, and throat and eye/orbital manifestations, more relapses, and higher survival than patients with MPA. GPA was the only independent risk factor for relapse. Poor survival predictors were older age at diagnosis and peripheral nerve involvement. ANCA serotypes differentiated clinical features in a lesser degree than clinical phenotypes. A mean of 1.5 biopsies were performed in 93.4% of patients in different territories. Overall, vasculitis was identified in 80.3% (97.3% in MPA and 61.8% in GPA) of patients. CONCLUSIONS: The identification of GPA presentations associated with MPO-ANCA and awareness of risk factors for relapse and mortality are important to guide proper therapeutic strategies in AAV patients. Biopsies of different affected territories should be pursued in difficult-to-diagnose patients based on their significant diagnostic yield.

RESUMO

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common entity (30%-40%) and can significantly limit the quality of life of patients, especially those that persist for more than 6 months after treatment (chronic neuropathy). Studies have shown a possible association between the presence of genetic polymorphisms in ABCB1 and the development of acute CIPN, although this relationship with chronic CIPN remains unexplored. This is an analytical observational case-control study defined by the presence (cases) or absence (controls) of CIPN at 6 months after the end of the neurotoxic drug. Our aim is to demonstrate whether these ABCB1 polymorphisms also influence the chronification of this toxicity, as well as the clinical factors that can help us to predict it. Methods: The study included 152 patients treated with tri-weekly oxaliplatin (O) or weekly paclitaxel (P); 86 cases and 66 controls. Clinical and analytical parameters were analysed including the study of ABCB1 genetic polymorphisms in a blood sample. Results: ABCB1 genetic polymorphisms C1236T (rs1128503) and C3435T (rs1045642) are associated with the development of chronic CIPN in patients treated with P. No differences were found in patients treated with O. Other predictive factors to be considered in the development of this toxicity are age >60 years, BMI ≥30, toxic habits and cardiovascular risk factors. Conclusion: CIPN is a common and understudied toxicity, despite being a limiting factor in the quality of life of many patients. As described in acute CIPN, our study demonstrates the relationship between chronic neuropathy and being a carrier of specific polymorphisms (C1236T and C3435T) of the ABCB1 gene in patients treated with P. In addition, there are modifiable factors (obesity, smoking, or alcohol) that may influence its development. Further prospective studies are needed to investigate genetic and clinical modifiable factors predisposing to CIPPN to develop prevention and treatment strategies.

RESUMO

Background: Coronary disease is the main cause of death around the world. mHealth technology is considered attractive and promising to promote behavioural changes aimed at healthy lifestyle habits among coronary patients. The purpose of this study is to evaluate the efficacy of an mHealth intervention regarding improved results in secondary prevention in patients after an acute myocardial infarction (AMI) or angina in terms of lifestyle, clinical variables and therapeutic compliance. Methods: Randomised clinical trial with 300 patients who underwent a percutaneous coronary intervention (PCI) with stent implant. They will be assigned to either the mHealth group, subject to a self-monitored educational intervention involving an internet application installed on their mobile phone or tablet, or to a control group receiving standard healthcare (150 patients in each arm). The primary outcome variables will be adherence to the Mediterranean diet, physical activity, smoking, therapeutic compliance, knowledge acquired, user-friendliness and satisfaction with the application. Measurements of blood pressure, heart rate, body weight, waist circumference (WC) and the 6-min walk test will be taken. Furthermore, the blood lipid profile, glucose and HbA1c will be evaluated. Clinical interview will be conducted, and validated questionnaires completed. The primary quantitative results will be compared using an analysis of covariance adjusted for age and sex. A multivariate analysis will be performed to examine the association of the intervention with lifestyle habits, the control of cardiovascular risk factors (CDRFs) and the results after the hospital discharge (major adverse events, treatment compliance and lifestyle). Conclusions: The study will provide evidence about the effectiveness of an mHealth intervention at improving the lifestyle of the participants and could be offered to patients with coronary disease to complement existing services.

RESUMO

Objectives: Myositis is a heterogeneous family of autoimmune muscle diseases. As myositis autoantibodies recognize intracellular proteins, their role in disease pathogenesis has been unclear. This study aimed to determine whether myositis autoantibodies reach their autoantigen targets within muscle cells and disrupt the normal function of these proteins. Methods: Confocal immunofluorescence microscopy was used to localize antibodies and other proteins of interest in myositis muscle biopsies. Bulk RNA sequencing was used to study the transcriptomic profiles of 668 samples from patients with myositis, disease controls, and healthy controls. Antibodies from myositis patients were introduced into cultured myoblasts by electroporation and the transcriptomic profiles of the treated myoblasts were studied by bulk RNA sequencing. Results: In patients with myositis autoantibodies, antibodies accumulated inside myofibers in the same subcellular compartment as the autoantigen. Each autoantibody was associated with effects consistent with dysfunction of its autoantigen, such as the derepression of genes normally repressed by Mi2/NuRD in patients with anti-Mi2 autoantibodies, the accumulation of RNAs degraded by the nuclear RNA exosome complex in patients with anti-PM/Scl autoantibodies targeting this complex, and the accumulation of lipids within myofibers of anti-HMGCR-positive patients. Internalization of patient immunoglobulin into cultured myoblasts recapitulated the transcriptomic phenotypes observed in human disease, including the derepression of Mi2/NuRD-regulated genes in anti-Mi2-positive dermatomyositis and the increased expression of genes normally degraded by the nuclear RNA exosome complex in anti-PM/Scl-positive myositis. Conclusions: In myositis, autoantibodies are internalized into muscle fibers, disrupt the biological function of their autoantigen, and mediate the pathophysiology of the disease.

RESUMO

Aloina catillum is a variable moss typical of xerophytic environments in the Neotropics, characterized against other closely allied Aloina species with well-differentiated leaf border by its setae twisted to the left throughout. In order to clarify its variability and its relationships with the allied species with differentiated leaf border A. brevirostris, A. obliquifolia, and A. rigida, we performed an integrative study including sequence data from four markers (nuclear ITS, plastid atpB-rbcL, trnG, trnL-F), morphometry, and species assembling by automatic partitioning (ASAP) algorithm. Our data suggest that A. catillum consists of at least three species: A. calceolifolia (an earlier name for A. catillum), and two species described here as a new, A. bracteata sp. nov. and A. limbata sp. nov. This latter species includes the specimens previously identified as A. obliquifolia from South America. Additionally, some morphological and molecular variability was also detected in A. limbata, but was not consistent enough to be recognized taxonomically. The study supports the presence of A. brevirostris in the Neotropics and A. rigida is tentatively excluded from South America. Full descriptions of the A. catillum s.l. species and a diagnostic key to this complex in South America are provided.

RESUMO

BACKGROUND: Antimicrobial resistance is a global health problem, due to morbidity, mortality, and healthcare costs. The misuse of antimicrobials is the main cause of antimicrobial resistance. The aim of this study was to report antimicrobial resistance and antibiotic consumption in a secondary care hospital in Mexico. METHODS: Within a cross-sectional study, antimicrobial resistance data on ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) and antibiotic consumption from 2020 to 2022 were collected. Antimicrobial resistance was reported based on percentages of resistance and consumption was analyzed using the defined daily dose (DDD)/100 bed days and the AWaRe (Access, Surveillance, Reservation) antibiotic group. RESULTS: Antibiotic consumption in 2020, 2021 and 2022 was 330, 175 and 175 DDD/100 beds day, respectively. The rate of ceftriaxone resistance in E. coli (n = 526) and K. pneumoniae (n = 80) was 76% and 69%, respectively, the rate of carbapenem resistance in A. baumannii (n = 168) and P. aeruginosa (n = 108) was 92% and 52%, respectively; the rate of oxacillin resistance in S. aureus (n = 208) was 27%; and the rate of vancomycin resistance in E. faecium (n = 68) was 47%. CONCLUSION: The reported results are congruent with global estimates of antibiotic resistance and consumption, providing an overview that could generate actions for antimicrobial optimization at the local and regional levels.

RESUMO

BACKGROUND: Sequential nab-paclitaxel plus gemcitabine followed by modified FOLFOX-6 (oxaliplatin, leucovorin, and 5-fluorouracil) (nab-P/Gem-mFOLFOX) showed a good safety and clinical profile in metastatic pancreatic ductal adenocarcinoma (mPDAC) in the phase I SEQUENCE trial. METHODS: The safety and efficacy of sequential nab-P/Gem-mFOLFOX was compared with standard nab-paclitaxel plus gemcitabine (nab-P/Gem) as first-line treatment in a multi-institutional, randomized, open-label, phase II trial in patients with untreated mPDAC. We randomly assigned patients in a 1:1 ratio to receive nab-P/Gem on days 1, 8, and 15 followed by mFOLFOX on day 29 of a 6-week cycle (experimental group) or nab-P/Gem on days 1, 8, and 15 of a 4-week cycle (control group). The primary end point was the 12-month overall survival rate. RESULTS: A total of 157 patients were randomly assigned: 78 to nab-P/Gem-mFOLFOX and 79 to nab-P/Gem. Patients receiving nab-P/Gem-mFOLFOX had a 12-month overall survival of 55.3% (95% confidence interval [CI], 44.2 to 66.5) versus 35.4% (95% CI, 24.9 to 46) in the control group (P=0.02). Similarly, the 24-month survival was 22.4% (95% CI, 13 to 31.8) with nab-P/Gem-mFOLFOX versus 7.6% (95% CI, 1.8 to 13.4) with control treatment. The median overall survival was 13.2 months (95% CI, 10.1 to 16.2) with nab-P/Gem-mFOLFOX and 9.7 months (95% CI, 7.5 to 12) with nab-P/Gem (hazard ratio for death, 0.68; 95% CI, 0.48 to 0.95). The safety profile showed a higher incidence of grade 3 or higher neutropenia (35 of 76 vs. 19 of 79 patients, P=0.004), grade 3 or higher thrombocytopenia (18 of 78 vs. 6 of 79 patients, P=0.007), and two treatment-related deaths (2.6%) with nab-P/Gem-mFOLFOX compared with none with control treatment. CONCLUSIONS: Sequential nab-P/Gem-mFOLFOX showed a significantly higher 12-month survival when compared with the standard nab-P/Gem treatment; this came with greater treatment toxicity.

RESUMO

AIM: To compare knowledge of Nursing Degree students about Best Practice Guidelines when there are included as teaching content in a subject vs knowledge through having the usual internship experience without teaching specific guidelines contents. DESIGN: Non-randomized post-test-only design with a comparison group. METHODS: 143 students of the nursing degree at the Autonomous University of Barcelona were recruited. The intervention group received a classroom training in three Best Practice Guidelines with Problem-Based Learning methodology. The comparison group only attended internship, without specific guidelines contents. Knowledge was evaluated with an ad hoc post intervention questionnaire. The information was collected between 2016 and 2018. RESULTS: The average score of knowledge was low, 5.1 out of 10, and differs between guides. The best results were obtained by the students with internships and that had consulted the guides on some occasions. Synchronized effort and leadership in Academia and Healthcare are needed to favour evidence-based practice. The combination of the consultation of the Best Practice Guidelines in theoretical learning combined with the practice, increases the knowledge of the Best Practice Guidelines and will favour the implementation of evidence-based practice. Some students were involved in questionnaire design.

RESUMO

Adalimumab biosimilar experience is still recent. Interchangeability differences could reduce persistence times. Our goal was to compare biosimilar persistence differences with a reference. A retrospective observational study was performed in three groups divided according to the adalimumab received. The primary outcome measure was persistence, represented with Kaplan-Meier analysis, and we secondarily evaluated security, efficacy, and biomarkers. We obtained approval from the regional ethical committee, and the study was conducted following the Helsinki Declaration as revised in 2013. Data from 104 patients were collected: 50 received the biosimilar, 29 received the reference, and 25 switched from the original to the biosimilar. After a follow-up of 12 months, the biosimilar's persistence was higher, without differences in mild adverse events per group. In contrast, there were differences in severe events, with the switched group's frequency being higher. Biomarkers were reduced at similar proportions in all groups, and 43% had a clinical response at week 20 without differences. Adalimumab biosimilars are a valuable option for IBD based on clinical equivalence that are less expensive than the original drug. Their use does not have a detrimental influence on disease, although there are a few nuances in terms of interchangeability. These results support increasing confidence in using biosimilars, thus promoting the better sustainability of health systems.

RESUMO

PURPOSE: To evaluate the self-reported perspectives of participants involved in the Previene Cádiz intervention for preventing pediatric overweight and obesity. DESIGN AND METHODS: This qualitative study collected information through the World Café technique. A purposive sample of 40 participants was used, of which 14 were schoolchildren, 12 were teachers, and 14 were parent volunteers. The data were segmented, and concepts were created and grouped into dimensions and categories. RESULTS: The participants confirmed they had learned new information and behaviors about healthy habits. Parental awareness was considered a crucial and necessary element in changing family habits; therefore, increasing the motivation of family members was deemed a critical task in public health interventions conducted in school settings. DISCUSSION: Despite the suitability of qualitative methodology to evaluate the perceptions of the main players in an educational intervention, scientific literature is scarce. Obtaining information from the educational community about an intervention is not always easy, so the perspectives of teachers, students, and families about the Previene Cádiz intervention through the World Café approach is considered a relevant contribution. CONCLUSIONS: The participants considered the intervention positive in terms of learning and fostering increased knowledge, awareness, and healthy behaviors. PRACTICE IMPLICATIONS: Future interventions should encourage the active participation of all social groups involved, integrating dynamic and collaborative training activities that are acceptable to all participants.

RESUMO

Background: The 1000-day period encompassing pregnancy and the first two years of postnatal life is critical for preventing childhood obesity. Existing interventions targeting this period have been characterised by great variability in duration, objectives, and evaluation indicators. We aimed to evaluate the impact of an intervention developed during the entire 1000-day period on body mass index and body fat percentage at two years of age. Methods: We designed a prospective, interventional, quasi-experimental study (ie, without randomisation or blinding of both groups) targeting mother-child pairs from the beginning of pregnancy up to two years of age belonging to the basic health area of Puerto Real (Cádiz). We developed and delivered an intervention from pregnancy to two years and assessed its effect. Results: The duration of breastfeeding and vitamin D supplementation increased significantly after the intervention. The intervention group showed lowed skinfolds values, a significantly lower body fat percentage, as well as a lower accumulation of factor at two years than the control group. Conclusions: The intervention has had an impact on body fat percentage at two years, potentially justified through its overall effect and the lower accumulation of early risk factors.

RESUMO

OBJECTIVE: To describe how a sample of people working in community health promotion projects perceive and implement community engagement approaches. METHOD: Mixed qualitative-quantitative study. Data was collected through: semi-structured interviews with 10 people representing the projects, and workshops in which 53 people participated and responded to a questionnaire prepared ad hoc to identify levels of community engagement. Descriptive statistical analysis of the questionnaires and framework analysis of the interviews, observations and workshops recordings. RESULTS: Although the projects are described as highly participatory, community engagement appeared mainly in the form of attending events, with few examples of consultation or community involvement. CONCLUSIONS: This difference may be due to the lack of a culture of participation, both in individuals and institutions, and lack of training in community engagement. It is proposed to change the language from participation-attendance to using expressions such as consulting or involving people.

RESUMO

BACKGROUND: Social justice is recognized by reputable international organizations as a professional nursing value. However, there are serious doubts as to whether it is embodied in Catalan nursing education. OBJECTIVES: To explore what nursing students take away from two teaching activities led by expert patients (one presentation and three expert patient illness narratives) on the topics of social justice, patient rights, and person-centered care. RESEARCH DESIGN: Qualitative study using a content analysis approach. The research plan included (1) think-pair-share activities (additional faculty-assisted presentation and three faculty-assisted, semi-structured scripted narratives); (2) paired reflections; (3) focus groups; and (4) content analysis of paired reflections and focus groups. PARTICIPANTS AND RESEARCH CONTEXT: Fourth-year nursing degree students at the Autonomous University of Barcelona (UAB), Spain. Convenience sampling was used. ETHICAL CONSIDERATIONS: The UAB Research Ethics Committee did not deem it necessary to apply any specific measures. We fully explained to patients that they could decide what medical information they would share with the students that was relevant to their learning, and we provided students with guidelines about patient confidentiality, dignity, and respect. FINDINGS/RESULTS: The students engaged in reflection about their education (recognizing that it had been centered on the professional and not the patient) and their relationship with the patient, in which they reproduced low-involvement patient care by modeling behaviors of their nurse educator. Moreover, they valued a person-centered care model with an emphasis on the emotional part but left out decision-making as an individual right of people. CONCLUSIONS: The think-pair-share activities were useful to spark self-reflection among students, who identified aspects to change in their own practice, and reflected about their own education process, both of which promote change.

RESUMO

High myopia is the most severe and pathological form of myopia. It occurs when the spherical refractive error exceeds -6.00 spherical diopters (SDs) or the axial length (AL) of the eye is greater than 26 mm. This article focuses on early-onset high myopia, an increasingly common condition that affects children under 10 years of age and can lead to other serious ocular pathologies. Through the genetic analysis of 21 families with early-onset high myopia, this study seeks to contribute to a better understanding of the role of genetics in this disease and to propose candidate genes. Whole-exome sequencing studies with a panel of genes known to be involved in the pathology were performed in families with inconclusive results: 3% of the variants found were classified as pathogenic, 6% were likely pathogenic and the remaining 91% were variants of uncertain significance. Most of the families in this study were found to have alterations in several of the proposed genes. This suggests a polygenic inheritance of the pathology due to the cumulative effect of the alterations. Further studies are needed to validate and confirm the role of these alterations in the development of early-onset high myopia and its polygenic inheritance.
