RESUMO

PURPOSE: Primary aim of the study was to investigate the status of different health-related quality of life (HRQoL) domains in postmenopausal women with osteoporosis and osteopenia, and to explore possible associations with bone microarchitecture and nutritional status. METHODS: This was a single-center cross-sectional study that included 232 postmenopausal women, from which they were divided into three groups-osteoporosis (OP, N = 63), osteopenia (OPIA, N = 123), and control group (N = 46). Detailed medical history data and anthropometric measurements were taken from all women. Bone structure parameters were taken with DXA device, with additional analysis of bone microarchitecture status with Trabecular Bone Score (TBS). Nutritional status was assessed with Mini Nutritional Assessment (MNA) questionnaire, and HRQoL with Medical Outcomes Study Short Form-36 (SF-36) questionnaire. RESULTS: Nutrition evaluation analysis have shown that patients in OP group had significantly lower values of MNA score compared to the OPIA group and control group (P = 0.005). Furthermore, a significant positive correlation was found between all of the SF-36 domains and MNA scores, while significant positive correlation was found between TBS values and Physical functioning (P < 0.001), Bodily pain (P = 0.027), Social functioning (P = 0.029), and Vitality domains (P = 0.041) in total investigated population. Further analyses were performed only in OP and OPIA groups, and TBS score showed significant positive correlation with Physical functioning (r = 0.248, P < 0.001) and Bodily pain domains as well (r = 0.180, P = 0.014), while MNA score positively correlated with each of the SF-36 domains. Multiple regression models have shown that MNA score retained significant association with each SF-36 domains, and TBS value with Physical functioning (P = 0.003), Social functioning (P = 0.012), and Vitality domains (P = 0.014). CONCLUSION: This study highlights the associations that TBS has with some domains of HRQoL in postmenopausal women with osteoporosis and osteopenia. Moreover, nutritional status could play a role in the complex interplay between TBS and HRQoL.

RESUMO

INTRODUCTION: The study aimed to determine satisfaction level with the quality of education among dental students and dentists in Croatia based on the acquired knowledge and clinical and soft skills. MATERIALS AND METHODS: An online cross-sectional survey was conducted among 533 dentists and dental students. The questionnaire consisted of four sections with closed-ended questions. The first section included personal and professional data, whereas the second to fourth sections assessed satisfaction with learned basic dental, professional technical or clinal and interpersonal social or soft skills on a 5-point Likert scale. The data were analysed using the Mann-Whitney U-test and linear regression analysis. The significance level was set at .05. RESULTS: When comparing satisfaction scores between dentists and dental students in terms of basic dental knowledge and skills learned, students showed higher satisfaction scores for the categories of "Emergency Medical Situations" (p = .005) and "Ergonomic Principles of Work" (p = .004). Dentists, on the other hand, showed higher satisfaction for the categories "Selection and use of local anaesthetics and local antibiotics" (p = .005, p = .026; respectively). For the type of technical skills from the different areas of dentistry, dentists were most satisfied with "Oral Surgery" (4.26 ± 0.85), while students were most satisfied with "Oral Medicine" (4.29 ± 0.89). Finally, when comparing satisfaction scores with social skills, dentists had lower satisfaction scores in all categories studied (p ≤ .05). CONCLUSION: Dental students showed higher overall satisfaction than dentists. The most significant satisfaction was expressed in technical skills learned, and the most considerable dissatisfaction was recorded in the unmeasurable skills category focused on "Career management".

RESUMO

The potential therapeutic benefits of cannabidiol (CBD) require further study. Here, we report a triple-blind (participant, investigator, and outcome assessor) placebo-controlled crossover study in which 62 hypertensive volunteers were randomly assigned to receive the recently developed DehydraTECH2.0 CBD formulation or a placebo. This is the first study to have been conducted using the DehydraTECH2.0 CBD formulation over a 12-week study duration. The new formulation's long-term effects on CBD concentrations in plasma and urine, as well as its metabolites 7-hydroxy-CBD and 7-carboxy-CBD, were analyzed. The results of the plasma concentration ratio for CBD/7-OH-CBD in the third timepoint (after 5 weeks of use) were significantly higher than in the second timepoint (after 2.5 weeks of use; p = 0.043). In the same timepoints in the urine, a significantly higher concentration of 7-COOH-CBD was observed p < 0.001. Differences in CBD concentration were found between men and women. Plasma levels of CBD were still detectable 50 days after the last consumption of the CBD preparations. Significantly higher plasma CBD concentrations occurred in females compared to males, which was potentially related to greater adipose tissue. More research is needed to optimize CBD doses to consider the differential therapeutic benefits in men and women.

RESUMO

According to current European Resuscitation Council guidelines, priorities in advanced life support in adult are chest compression with minimal interruption and early defibrillation. Endotracheal intubation is still considered the gold standard in airway management, but guidelines suggest that securing the airway be incremental, ranging from basic techniques to more complex ones. Doctors who work in pre-hospital emergency medicine teams (EMT) in Croatia usually lack sufficient education and expertise. The aim of this study was to determine whether there was a significant difference in recovery of spontaneous circulation during cardiopulmonary resuscitation (CPR) in out-of-hospital setting depending on the EMT airway management technique of choice. This retrospective analysis included data collected during a 10-year period at the Krapina-Zagorje County Emergency Medicine Institute on all patients with CPR performed by EMTs 20 minutes from initial emergency call. The airway management groups included oropharyngeal tube, i-gel supraglottic device, and endotracheal tube. There were 968 patients, mean age 70. In 74.61% of patients, the cause of arrest was of cardiac etiology. Our study did not find a statistically significant in difference of CPR success among the three groups analyzed according to the airway management technique of choice (p=0.74, χ2-test).

RESUMO

PURPOSE: Orthorexia nervosa (ON) is an eating behavior where patients obsessively try to reach health through "purity" of food. Narcissism is a personality trait characterized with the self-belief of grandiosity, importance and need of appreciation. Both of these conditions are connected through self-image in way of reaching perfection through health and body image, whereas one of the ways for reaching it is exercising. This cross-sectional study aimed to investigate ON and its possible association with narcissism in fitness center users. METHODS: The study included 1017 fitness center users and three questionnaires were used for the assessment: general information, ORTO-R and Narcissistic personality inventory-13 (NPI-13). RESULTS: There was a significant negative correlation (r = - 0.467, p < 0.001) between the ORTO-R score and the NPI-13 score. Comparison of the ORTO-R score between different durations of using a fitness center showed statistically significant differences (H = 134.72, p < 0.001). The subjects who are using the fitness center for less than 1 year have the highest ORTO-R score, while those who are using it 1-3 years have the lowest ORTO-R score. Moreover, multiple linear regression showed that ORTO-R score retained significant association with NPI-13 (ß ± SE, - 0.416 ± 0.026, p < 0.001) and the duration of using a fitness center (0.576 ± 0.068, p < 0.001) after model adjustment for age and BMI. CONCLUSION: These results are implying that fitness center users could possibly be vulnerable of developing ON and that there is a strong association between ON and narcissism in this population. However, future larger-scale longitudinal studies are needed to address these findings. LEVEL OF EVIDENCE: Level V, cross-sectional survey-based study.

RESUMO

With the rising prevalence of Inflammatory bowel disease (IBD) worldwide, and the rising cost of treatment with novel biological drugs, there is an increasing interest in various diets and natural foods as a potential way to control/modulate IBD. As recent data indicates that diet can modify the metabolic responses essential for the resolution of inflammation, and as wine compounds have been shown to provide substantial anti-inflammatory effect, in this review we aimed to discuss the current evidence concerning the impact of biological compounds present in wine on IBD. A number of preclinical studies brought forth strong evidence on the mechanisms by which molecules in wine, such as resveratrol or piceatannol, provide their anti-inflammatory, anti-oxidative, anti-tumor, and microbiota-modulation effects. However, concerning the effects of alcohol, it is still unclear how the amount of ethanol ingested within the framework of moderate wine consumption (1-2 glasses a day) affects patients with IBD, as human studies regarding the effects of wine on patients with IBD are scarce. Nevertheless, available evidence justifies the conductance of large-scale RCT trials on human subjects that will finally elucidate whether wine can offer real benefits to the IBD population.

RESUMO

Background: To investigate association between optic disc parameters analyzed by optical coherence tomography (OCT) and occurrence of peripheral retinal tears in patients with symptomatic posterior vitreous detachment (PVD). Methods: This cross-sectional study enrolled 75 patients with symptoms of acute PVD, who were allocated into two groups based on whether a peripheral retinal tear occurred or not. Results: When comparing the average retinal nerve fiber layer (RNFL) thickness (µm) between retinal tear and control groups, it was shown that patients with a retinal tear have a significantly higher (87.18 [95% confidence interval (CI), 84.47 to 89.9] vs 81.14 [95% CI, 77.81 to 84.46], P = 0.005) average RNFL thickness. Furthermore, we observed a significant difference (0.13, 0.06 to 0.22 vs 0.07, 0.04 to 0.1, P = 0.036, Mann-Whitney U-test) in the size of cup volume (mm3) between the tear and control groups, respectively. Linear regression showed a significant decrease (P = 0.029) in average RNFL thickness with increasing age, but without a significant difference between the two groups. There was no statistically significant difference between the tear and control groups in terms of rim area, disc area, and average cup-to-disc ratio. Conclusion: Patients with a higher average RNFL thickness and larger cup volume measured by OCT were more prone to develop a peripheral retinal tear. Increased peripapillary average RNFL thickness due to trauma and subsequent inflammation, possibly related to the more adherent posterior hyaloid membrane to the retina, may also indicate strengthened adhesions in the areas of the peripheral retina where retinal tears occur. OCT analysis of the optic nerve head may be used in everyday clinical practice as a predictor of the development of peripheral retinal tears in patients with symptomatic PVD.

RESUMO

The diagnosis of acute appendicitis and concurrent surgery referral is primarily based on clinical presentation, laboratory and radiological imaging. However, utilizing such an approach results in as much as 10-15% of negative appendectomies. Hence, in the present study, we aimed to develop a machine learning (ML) model designed to reduce the number of negative appendectomies in pediatric patients with a high clinical probability of acute appendicitis. The model was developed and validated on a registry of 551 pediatric patients with suspected acute appendicitis that underwent surgical treatment. Clinical, anthropometric, and laboratory features were included for model training and analysis. Three machine learning algorithms were tested (random forest, eXtreme Gradient Boosting, logistic regression) and model explainability was obtained. Random forest model provided the best predictions achieving mean specificity and sensitivity of 0.17 ± 0.01 and 0.997 ± 0.001 for detection of acute appendicitis, respectively. Furthermore, the model outperformed the appendicitis inflammatory response (AIR) score across most sensitivity-specificity combinations. Finally, the random forest model again provided the best predictions for discrimination between complicated appendicitis, and either uncomplicated acute appendicitis or no appendicitis at all, with a joint mean sensitivity of 0.994 ± 0.002 and specificity of 0.129 ± 0.009. In conclusion, the developed ML model might save as much as 17% of patients with a high clinical probability of acute appendicitis from unnecessary surgery, while missing the needed surgery in only 0.3% of cases. Additionally, it showed better diagnostic accuracy than the AIR score, as well as good accuracy in predicting complicated acute appendicitis over uncomplicated and negative cases bundled together. This may be useful in centers that advocate for the conservative treatment of uncomplicated appendicitis. Nevertheless, external validation is needed to support these findings.

RESUMO

Antimicrobial resistance is recognised as one of the top threats healthcare is bound to face in the future. There have been various attempts to preserve the efficacy of existing antimicrobials, develop new and efficient antimicrobials, manage infections with multi-drug resistant strains, and improve patient outcomes, resulting in a growing mass of routinely available data, including electronic health records and microbiological information that can be employed to develop individualised antimicrobial stewardship. Machine learning methods have been developed to predict antimicrobial resistance from whole-genome sequencing data, forecast medication susceptibility, recognise epidemic patterns for surveillance purposes, or propose new antibacterial treatments and accelerate scientific discovery. Unfortunately, there is an evident gap between the number of machine learning applications in science and the effective implementation of these systems. This narrative review highlights some of the outstanding opportunities that machine learning offers when applied in research related to antimicrobial resistance. In the future, machine learning tools may prove to be superbugs' kryptonite. This review aims to provide an overview of available publications to aid researchers that are looking to expand their work with new approaches and to acquaint them with the current application of machine learning techniques in this field.

RESUMO

Background: Recent data indicate that cannabidiol (CBD), a nonintoxicating constituent of cannabis, is involved in several aspects of cardiovascular regulation, including blood pressure (BP). However, the impact of chronic CBD administration on 24-h BP and vascular health has not been previously examined in patients with hypertension. The primary aim of this randomized, triple-blind, placebo-controlled, and crossover study was to examine the influence of chronic CBD on 24-h ambulatory BP and arterial stiffness in hypertensive patients. Methods: Seventy patients with mild or moderate primary hypertension, who were untreated or receiving standard of care therapy, were randomly assigned to receive either 5 weeks of oral CBD or placebo-matched controls. Following a >2-week washout period, patients were crossed over to alternate therapy. The primary outcome of the study was dynamic in 24-h ambulatory BP and was assessed using two-way repeated measure analysis of variance. Results: Administration of CBD reduced average 24 h mean, systolic, and diastolic BP after 2.5 weeks (-3.22±0.90 mmHg [95% confidence interval -1.01 to -5.44 mmHg], -4.76±1.24 mmHg [-1.72 to -7.80 mmHg], and -2.25±0.80 mmHg [-0.30 to -6.01 mmHg], respectively (all p<0.05); however, these values largely remained stable following the uptitration of CBD dosing. There were no changes in liver enzymes or serious adverse events (AEs). There was no significant difference in pulse wave velocity (group×factor interaction: F=1.50, p=0.226) at different time points, regardless of the intervention arm. Conclusions: In conclusion, chronic administration of CBD reduces ambulatory BP in those with untreated and treated hypertension. In addition, lack of serious AEs implies safety and tolerability of the above-noted CBD formulation. ClinicalTrials.gov ID: NCT05346562, Registered April 6th 2022.

RESUMO

It has been well established that diabetes mellitus (DM) is considered as a core risk factor for the development of cardiovascular diseases. However, what is less appreciated is the fact that DM may affect cardiac function irrespective of cardiac pathologies to which it contributes, such as coronary artery disease and hypertension. Although echocardiography provides accurate and reproducible diagnostic and prognostic data in patients with DM, its use in these patients is still underappreciated, resulting in progression of DM-related heart failure in many patients. Hence, in the present review, we aimed to discuss the role of echocardiography in the contemporary management of diabetic cardiomyopathy (DCM), as well as the role of emerging echocardiographic techniques, which may contribute to earlier diagnosis and more appropriate management of this complication of DM. In order to improve outcomes, focus must be placed on early diagnosis of this condition using a combination of echocardiography and emerging biomarkers, but perhaps the more important thing is to change perspective when it comes to the clinical importance of DCM.

RESUMO

Data concerning the effects of cannabidiol (CBD) on blood pressure (BP) is controversial. HYPER-H21-4 was a randomized, placebo-controlled, crossover trial which sought to elucidate if 5-week administration of CBD will reduce BP in hypertensive patients. In the substudy of this trial, we aimed to establish the mechanistic background of CBD-induced BP reduction. Specifically, we explored the dynamic of catestatin, a sympathoinhibitory peptide implicated in the pathophysiology of hypertension. In the present analysis, 54 patients with Grade 1 hypertension were included. 5-week administration of CBD but not placebo reduced serum catestatin concentration in comparison to baseline (13.50 [10.85-19.05] vs. 9.65 [6.37-12.26] ng/mL, p < 0.001). Serum catestatin levels at the start of the treatment period demonstrated a negative correlation with the extent of reduction in mean arterial pressure (r = -0.474, p < 0.001). Moreover, the extent of change in catestatin serum levels showed a strong correlation with the extent of mean arterial pressure reduction (r = 0.712, p < 0.001). Overall, the results of the present study imply that the antihypertensive effects of CBD may be explained by its interaction with the sympatho-chromaffin system, although further research is warranted.

RESUMO

Breast cancer is a significant health issue affecting women worldwide, and accurately detecting lymph node metastasis is critical in determining treatment and prognosis. While traditional diagnostic methods have limitations and complications, artificial intelligence (AI) techniques such as machine learning (ML) and deep learning (DL) offer promising solutions for improving and supplementing diagnostic procedures. Current research has explored state-of-the-art DL models for breast cancer lymph node classification from radiological images, achieving high performances (AUC: 0.71-0.99). AI models trained on clinicopathological features also show promise in predicting metastasis status (AUC: 0.74-0.77), whereas multimodal (radiomics + clinicopathological features) models combine the best from both approaches and also achieve good results (AUC: 0.82-0.94). Once properly validated, such models could greatly improve cancer care, especially in areas with limited medical resources. This comprehensive review aims to compile knowledge about state-of-the-art AI models used for breast cancer lymph node metastasis detection, discusses proper validation techniques and potential pitfalls and limitations, and presents future directions and best practices to achieve high usability in real-world clinical settings.

RESUMO

HYPER-H21-4 was a randomized crossover trial that aimed to determine if cannabidiol (CBD), a non-intoxicating constituent of cannabis, has relevant effects on blood pressure and vascular health in patients with essential hypertension. In the present sub-analysis, we aimed to elucidate whether serum urotensin-II concentrations may reflect hemodynamic changes caused by oral supplementation with CBD. The sub-analysis of this randomized crossover study included 51 patients with mild to moderate hypertension that received CBD for five weeks, and placebo for five weeks. After five weeks of oral CBD supplementation, but not placebo, serum urotensin concentrations reduced significantly in comparison to baseline (3.31 ± 1.46 ng/mL vs. 2.08 ± 0.91 ng/mL, P < 0.001). Following the five weeks of CBD supplementation, the magnitude of reduction in 24 h mean arterial pressure (MAP) positively correlated with the extent of change in serum urotensin levels (r = 0.412, P = 0.003); this association was independent of age, sex, BMI and previous antihypertensive treatment (ß ± standard error, 0.023 ± 0.009, P = 0.009). No correlation was present in the placebo condition (r = -0.132, P = 0.357). In summary, potent vasoconstrictor urotensin seems to be implicated in CBD-mediated reduction in blood pressure, although further research is needed to confirm these notions.

RESUMO

BACKGROUND: Due to recent changes in breast cancer treatment strategy, significantly more patients are treated with neoadjuvant systemic therapy (NST). Radiological methods do not precisely determine axillary lymph node status, with up to 30% of patients being misdiagnosed. Hence, supplementary methods for lymph node status assessment are needed. This study aimed to apply and evaluate machine learning models on clinicopathological data, with a focus on patients meeting NST criteria, for lymph node metastasis prediction. METHODS: From the total breast cancer patient data (n = 8381), 719 patients were identified as eligible for NST. Machine learning models were applied for the NST-criteria group and the total study population. Model explainability was obtained by calculating Shapley values. RESULTS: In the NST-criteria group, random forest achieved the highest performance (AUC: 0.793 [0.713, 0.865]), while in the total study population, XGBoost performed the best (AUC: 0.762 [0.726, 0.795]). Shapley values identified tumor size, Ki-67, and patient age as the most important predictors. CONCLUSION: Tree-based models achieve a good performance in assessing lymph node status. Such models can lead to more accurate disease stage prediction and consecutively better treatment selection, especially for NST patients where radiological and clinical findings are often the only way of lymph node assessment.

RESUMO

Obesity is a disorder identified by an inappropriate increase in weight in relation to height and is considered by many international health institutions to be a major pandemic of the 21st century. The gut microbial ecosystem impacts obesity in multiple ways that yield downstream metabolic consequences, such as affecting systemic inflammation, immune response, and energy harvest, but also the gut-host interface. Metabolomics, a systematized study of low-molecular-weight molecules that take part in metabolic pathways, represents a serviceable method for elucidation of the crosstalk between hosts' metabolism and gut microbiota. In the present review, we confer about clinical and preclinical studies exploring the association of obesity and related metabolic disorders with various gut microbiome profiles, and the effects of several dietary interventions on gut microbiome composition and the metabolome. It is well established that various nutritional interventions may serve as an efficient therapeutic approach to support weight loss in obese individuals, yet no agreement exists in regard to the most effective dietary protocol, both in the short and long term. However, metabolite profiling and the gut microbiota composition might represent an opportunity to methodically establish predictors for obesity control that are relatively simple to measure in comparison to traditional approaches, and it may also present a tool to determine the optimal nutritional intervention to ameliorate obesity in an individual. Nevertheless, a lack of adequately powered randomized trials impedes the application of observations to clinical practice.

RESUMO

Accumulating data from both human and animal studies suggest that cannabidiol (CBD) may be associated with improved cardiovascular function, markedly with regard to reduction in blood pressure and improved endothelial function. However, there is a lack of randomized studies to support these notions, especially in at-risk populations. The principal aim of this randomized, placebo-controlled, and crossover study is to examine the influence of chronic CBD administration on 24-h blood pressure in individuals with mild or moderate hypertension who are either untreated or receiving standard care therapy. The secondary aims of the study are to determine the safety and tolerability of 5 weeks of CBD administration, and to quantify the effect on arterial stiffness, CBD and vascular health biomarkers, inflammation, heart rate variability, and psychological well-being in both groups of patients. The present single-center study is designed as a triple blind (Participant, Investigator, Outcomes Assessor), placebo-controlled, crossover pilot study in which 70 hypertensive volunteers (aged 40-70 years) will receive DehydraTECH2.0 CBD formulation and placebo in a crossover manner. We believe that comprehensive analyses that will be performed in the present trial will decipher whether CBD is in fact a safe and valuable supplement for patients with treated and untreated hypertension.

RESUMO

Accumulating data suggests that catestatin, an eclectic neuroendocrine peptide, is involved in the pathophysiology of primary hypertension (PH). Nevertheless, clinical studies concerning its role in PH are still scarce. Therefore, in the present study, we aimed to explore an association between serum catestatin levels, ambulatory blood pressure (BP) and arterial stiffness in patients with PH and healthy controls. In this single-center study, 72 patients aged 40−70 diagnosed with PH, and 72 healthy controls were included. In patients with PH, serum catestatin concentrations were significantly higher in comparison to the healthy controls (29.70 (19.33−49.48) ng/mL vs. 5.83 (4.21−8.29) ng/mL, p < 0.001). Untreated patients had significantly higher serum catestatin than patients treated with antihypertensive drugs (41.61 (22.85−63.83) ng/mL vs. 24.77 (16.41−40.21) ng/mL, p = 0.005). Multiple linear regression analysis showed that serum catestatin levels retained a significant association with mean arterial pressure (ß ± standard error, 0.8123 ± 0.3037, p < 0.009) after model adjustments for age, sex and body mass index. Finally, catestatin levels positively correlated with pulse wave velocity (r = 0.496, p < 0.001) and central augmentation index (r = 0.441, p < 0.001), but not with peripheral resistance. In summary, increased serum catestatin concentration in PH, predominantly in the untreated subgroup, and its association with ambulatory BP and arterial stiffness address the role of this peptide in PH.

RESUMO

With the rising global burden of inflammatory bowel disease (IBD) and the rising costs of novel biological drugs, there is an increasing need for dietary approaches and functional foods that could modulate the course of IBD. The Mediterranean diet has proven to be efficacious in managing chronic inflammatory diseases, and recent studies have also shown its benefits in the setting of IBD. Since olive oil and its compounds have been shown to provide a considerable anti-inflammatory effect, in this review, we aim to discuss the latest evidence concerning the impact of olive oil and its bioactive compounds on IBD. Numerous preclinical studies have exhibited solid evidence on the mechanisms by which polyphenol-rich extra-virgin olive oil (EVOO) or specific polyphenols like hydroxytyrosol (HT) provide their anti-inflammatory, antioxidative, antitumour, and microbiota-modulation effects. Accordingly, several human studies that explored the effects of olive oil on patients with IBD further confirmed the evidence brought forward by preclinical studies. Nevertheless, there is a need for larger-scale, multicentric, randomized control trials that would finally elucidate olive oil's level of efficacy in modulating the course of IBD.

RESUMO

Among many lifestyle components that professional athletes have to follow, nutrition is gradually growing to be one of the key factors for achieving and maintaining optimal sport performance. The Mediterranean diet (MD) is recognized as one of the healthiest dietary patterns worldwide; however, data regarding adherence to the MD among professional athletes are still scarce. Moreover, with the imposed need for a healthy diet among professional athletes, orthorexia nervosa (ON) could become a rising issue. This cross-sectional study included 150 professional athletes and 150 matched recreational athletes from Croatia. Four questionnaires were used for the assessment: general information, a test for the diagnosis of ON (ORTO-15), the International Physical Activity Questionnaire (IPAQ) and the Mediterranean Diet Serving Score (MDSS). Significantly more professional athletes were adherent to the MD (p < 0.001) and had a tendency to ON (p < 0.001). Moreover, there was a significant negative correlation between the ORTO-15 score and the total MET min/week score (r = -0.524, p < 0.001) and a significant positive correlation between the MDSS score and the total MET min/week score in the professional athlete group (r = 0.478, p < 0.001). All of these results imply that professional athletes are more concentrated on their dietary patterns than recreational athletes, and that due to this dedication, they possibly have a higher adherence to the MD but also possibly a higher risk for developing ON. However, the association between ON and the MD should be further addressed in the future.
