Explorative Characterization of GI Complaints, General Physical and Mental Wellbeing, and Gut Microbiota in Trained Recreative and Competitive Athletes with or without Self-Reported Gastrointestinal Symptoms.

The current state of the literature lacks a clear characterization of gastrointestinal (GI) symptoms, gut microbiota composition, and general physical and mental wellbeing in well-trained athletes. Therefore, this study aimed to characterize differences in self-reported symptoms, gut microbiota composition, and wellbeing (i.e., sleep quality, mood, and physical (PHQ) and mental wellbeing) between athletes with and without GI symptoms. In addition, we assessed the potential impact of a 3-week multi-ingredient fermented whey supplement in the GI complaints group, without a control group, on the gut microbiota and self-reported GI symptoms and wellbeing. A total of 50 athletes (24.7 ± 4.5 years) with GI issues (GI group at baseline, GI-B) and 21 athletes (25.4 ± 5.3 years) without GI issues (non-GI group, NGI) were included. At baseline, there was a significant difference in the total gastrointestinal symptom rating scale (GSRS) score (24.1 ± 8.48 vs. 30.3 ± 8.82, p = 0.008) and a trend difference in PHQ (33.9 ± 10.7 vs. 30.3 ± 8.82, p = 0.081), but no differences (p > 0.05) were seen for other outcomes, including gut microbiota metrics, between groups. After 3-week supplementation, the GI group (GI-S) showed increased Bifidobacterium relative abundance (p < 0.05), reported a lower number of severe GI complaints (from 72% to 54%, p < 0.001), and PHQ declined (p = 0.010). In conclusion, well-trained athletes with GI complaints reported more severe GI symptoms than an athletic reference group, without showing clear differences in wellbeing or microbiota composition. Future controlled research should further investigate the impact of such multi-ingredient supplements on GI complaints and the associated changes in gut health-related markers.

Evaluating the Effects of Corn Flour Product Consumption on Cardiometabolic Outcomes and the Gut Microbiota in Adults with Elevated Cholesterol: A Randomized Crossover.

BACKGROUND: Consumption of whole grains is associated with a reduction in chronic diseases and offers benefits for cardiovascular health and metabolic regulation. The relationship between whole-grain corn and corn bran with the gut microbiota (GM) remains an area of growing interest, particularly regarding their influence on cardiometabolic health. OBJECTIVES: To investigate the effects of different corn flours on cardiometabolic outcomes and GM changes in adults with elevated low-density lipoprotein cholesterol (LDL cholesterol) concentrations. METHODS: In this crossover study, 36 adults with LDL cholesterol above 110 mg/L consumed 48 g/d of 3 corn flour types for 4 wk: whole-grain corn meal, refined corn meal (RCM), and a blend of RCM and corn bran (RCM + B). We assessed the impact on cardiometabolic markers [LDL cholesterol, high-density lipoprotein cholesterol (HDL cholesterol), total cholesterol, and triglycerides)] and GM composition and estimated function. Statistical analyses included mixed-effects modeling and responder (>5% decrease in LDL cholesterol) analysis to evaluate changes in GM related to lipid profile improvements. RESULTS: Of the 3 corn flour types, only RCM + B significantly decreased LDL cholesterol over time (-10.4 ± 3.6 mg/L, P = 0.005) and marginally decreased total cholesterol (-9.2 ± 3.9, P = 0.072) over time. There were no significant effects on HDL cholesterol or triglyceride concentrations. No significant changes were observed in GM alpha diversity, whereas beta diversity metrics indicated individual variability. Two genera, unclassified Lachnospiraceae and Agathobaculum (Padj ≤ 0.096), differed significantly by treatment, but only Agathobaculum remained significantly elevated in the whole-grain corn meal, compared to RCM and RCM + B, after adjustment for multiple comparisons. CONCLUSIONS: The type of corn flour, particularly RCM + B, notably influenced LDL cholesterol concentrations in adults with elevated LDL cholesterol. This study suggests that incorporating milled fractions (e.g., bran) of whole-grain corn with refined corn flour may be a viable alternative to supplementing manufactured grain products with isolated or synthetic fibers for improved metabolic health. This trial was registered at clinicaltrials.gov as NCT03967990.

Spontaneous intoxication of sheep by the pollen beetle Astylus atromaculatus: 4 outbreaks in Uruguay and Argentina.

Astylus atromaculatus Blanchard is a native beetle of South America that feeds on pollen. During the summer of 2022-2023 in Argentina and Uruguay, an explosive infestation of these insects occurred in pastures in which ruminants were grazing. This was believed to be associated with a severe drought, which had significantly reduced the flowering of crops. Three farms in Uruguay and one in Argentina were visited to examine the flocks and perform autopsies. Affected sheep had watery diarrhea, anorexia, depression, and ruminal atony. The average morbidity, mortality, and case fatality rates were 7.5%, 4.3%, and 68%, respectively. The main gross findings in all animals were in the jejunum; the serosa had multifocal hemorrhages, and the mucosa was necrotic and covered by a pseudomembrane. Microscopically, the mucosa had partial-to-complete necrosis of the lamina propria, as well as loss of villus and crypt epithelium with neutrophilic infiltration. Overlying the necrotic mucosa was a pseudomembrane of fibrin, cell debris, desquamated epithelial cells, degenerate neutrophils, and bacteria. Many specimens of A. atromaculatus were in all paddocks in which sheep grazed, as well as in the ruminal content of the autopsied animals.

Efficacy and safety of bemiparin as treatment of venous thromboembolic disease in the elderly.

BACKGROUND: As the elderly population continues to grow worldwide, it becomes crucial to explore safe and effective treatment options to manage venous thromboembolic disease in this vulnerable demographic group. METHODS: We carried out a retrospective cohort study (January 2017-December 2021) to analyse the efficacy and safety of bemiparin as a treatment for venous thromboembolic disease in 223 patients. We compared patients aged ≥65 years (elderly; n = 153) with patients aged less than 65 years (adults; n = 70) for a combined end point of death, recurrent thromboembolism, and major bleeding at 30 days. RESULTS: Elderly (mean age 79 ± 7.7 years) and adult patients (mean age 51.5 ± 11.6 years) received similar bemiparin doses 8470 ± 2362 International units (IU)/d versus 8754 ± 1593 IU/d, during a similar median [Interquartile range] period of 28 [9-118] versus 30 [10-90] days, respectively. At 30-day follow up a total of 24 elderly patients (15.7%), reached at least one of the end points, as compared with six adult patients (8.6%) (absolute difference 7.1%; 95% confidence interval [95% CI], -1.6 to 15.8). Recurrence of venous thromboembolic disease occurred in five elderly patients (3.3%) and in five adult patients (7.1%) (absolute difference -3.9%; 95% CI, -10.5 to 2.8). There were two episodes of major bleeding each in elderly (1.3%) and adult (2.9%) patients (absolute difference -1.6%; 95% CI, -5.8 to 2.7). CONCLUSION: Bemiparin showed a similar efficacy and safety profile in the treatment of venous thromboembolic disease in elderly and adult patients.

Enhancing Essential Oil Extraction from Lavandin Grosso Flowers via Plasma Treatment.

This study explores the impact of plasma treatment on Lavandin Grosso flowers and its influence on the extraction of essential oils (EOs) via hydrodistillation. Short plasma treatment times enhance the yield of EO extraction from 3.19% in untreated samples to 3.44%, corresponding to 1 min of plasma treatment, while longer treatment times (10 min) show diminishing returns to 3.07% of yield extraction. Chemical characterization (GC/MS and ATR-FTIR) indicates that plasma treatments do not significantly alter the chemical composition of the extracted EOs, preserving their aromatic qualities. Investigations into plasma-surface interactions reveal changes at the nanometer level, with XPS confirming alterations in the surface chemistry of Lavandin Grosso flowers by reducing surface carbon and increasing oxygen content, ultimately resulting in an increased presence of hydrophilic groups. The presence of hydrophilic groups enhances the interaction between the surface membrane of the glandular trichomes on Lavandin Grosso flowers and water vapor, consequently increasing the extraction of EOs. Furthermore, microscopic SEM examinations demonstrate that plasma treatments do not affect the morphology of glandular trichomes, emphasizing that surface modifications primarily occur at the nanoscale. This study underscores the potential of plasma technology as a tool to enhance EO yields from botanical sources while maintaining their chemical integrity.

A Novel Case of Concomitant PHEX and ALPL Mutation In a Family With Rickets.

Currently, no published cases report concomitant X-linked hypophosphatemia (XLH) and adult hypophosphatasia (HPP). Both diseases share clinical phenotypes that are almost indistinguishable. The correct diagnosis may be missed without a standardized laboratory and genetic testing approach. Pathogenic variants in the phosphate regulating endopeptidases homolog X-linked gene (PHEX) and the tissue-nonspecific alkaline phosphatase gene (ALPL) are genes that cause XLH and HPP, respectively. We describe a concomitant yet undescribed genetic pathogenic variant in a family. A 61-year-old woman was referred by orthopedic surgery for the presence of bilateral leg bowing and short stature during the assessment of knee surgery. The patient had a biochemical workup relevant for low serum phosphorus and 1,25-dihydroxy vitamin D and normal alkaline phosphatase (ALP). Genetic analysis revealed pathogenic variants in PHEX and ALPL. Her 42-year-old daughter shared identical symptoms and genetic variants with her mother. Both patients started conventional treatment for XLH with phosphorus and vitamin D, and the daughter later switched to burosumab-twza. Adult XLH and HPP may have similarities in clinical presentation but differ in some essential laboratory findings. Normal ALP levels helped direct our diagnosis toward XLH. However, the diagnosis was challenging due to the presence of concurrent variants in the genes involved. These variants illustrate the significant heterogeneity of the clinical expression.

West Indian Punctate Keratopathy and "Puerto Rican (PR) Spots".

This study describes the clinical characteristics of a cohort of Hispanic patients living in Puerto Rico who were found to have West Indian punctate keratopathy (WIPK). This case also introduces the term "PR (Puerto Rican) spots" to describe the dots observed in the eyes of individuals with WIPK who have a documented history of residing in Puerto Rico. The methods of the study consist of a retrospective chart review of patients presenting with WIPK. The patient data were entered retrospectively into a new database and analyzed. Eighteen patients who had WIPK were identified. The median age at presentation was 60.5 years (range: 49-72); 61.1% were female. At presentation, only one patient had both eyes affected. The median number of PR spots on examination was 1 (range: 1-4). All the patients had a history of ocular disease, most frequently glaucoma (55.5%), and had lived in Puerto Rico for more than 40 years. A total of 33.3% of the patients were retired or unemployed at the time of their presentation. While the origin of these dots remains unclear, ongoing efforts to document and characterize WIPK and PR spots will persist, with the aim of enhancing our understanding of this clinical entity.

Global dataset of soil organic carbon in tidal marshes.

Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil depth, site name, dry bulk density, SOC, and/or soil organic matter (SOM). The MarSOC dataset includes 17,454 data points from 2,329 unique locations, and 29 countries. We generated a general transfer function for the conversion of SOM to SOC. Using this data we estimated a median (± median absolute deviation) value of 79.2 ± 38.1 Mg SOC ha-1 in the top 30 cm and 231 ± 134 Mg SOC ha-1 in the top 1 m of tidal marsh soils globally. This data can serve as a basis for future work, and may contribute to incorporation of tidal marsh ecosystems into climate change mitigation and adaptation strategies and policies.

Bilateral Acute Iris Transillumination Syndrome Following Oral Moxifloxacin Overdose.

We report a case of bilateral acute iris transillumination (BAIT) syndrome caused by an overdose of oral moxifloxacin in a Hispanic female patient with no previous respiratory viral infection. A 56-year-old Hispanic female with no history of ocular illness was referred to our glaucoma service to manage her microcystic edema, swelling, and refractory ocular hypertension. Her ocular and systemic symptoms, including progressively worsening bilateral ocular pain, severe photophobia, blurred vision, nausea, and vomiting, started 14 days after an accidental overdose of oral moxifloxacin. Moxifloxacin had been prescribed to treat a complicated urinary tract infection. A slit-lamp examination revealed bilateral microcystic corneal edema and transillumination in the right temporal iris, both consistent with a diagnosis of BAIT syndrome. The existing literature on BAIT syndrome is scarce, and its etiology remains unclear. This case provides clinical evidence supporting moxifloxacin toxicity as a possible cause of BAIT syndrome. We emphasize the importance of conducting extensive research to define the mechanisms involved in moxifloxacin-induced BAIT syndrome and to search for other potential etiologies of this condition.

West Indian (Caribbean) Punctate Keratopathy in a Puerto Rican Girl.

We report on a case of West Indian (Caribbean) punctate keratopathy (WIPK) in a pediatric patient living in Puerto Rico, USA. A 9-year-old Hispanic girl presented for a routine ophthalmic follow-up. The patient had a history of juvenile idiopathic arthritis and chronic bilateral anterior uveitis. At the presentation, her visual acuity was 20/30 in the right eye and 20/20 in the left eye. An examination of the right eye was remarkable for one round, white subepithelial corneal opacity of approximately 0.1 mm in height by 0.1 mm in width, located slightly lateral to the center of the cornea, which was consistent with WIPK. This case highlights the importance of recognizing WIPK in children who have a history of living on any one or more of the Caribbean islands.

Germination and First Stages of Growth in Drought, Salinity, and Cold Stress Conditions of Plasma-Treated Barley Seeds.

Numerous works have demonstrated that cold plasma treatments constitute an effective procedure to accelerate seed germination under nonstress conditions. Evidence also exists about a positive effect of plasmas for germination under environmental stress conditions. For barley seeds, this work studies the influence of cold plasma treatments on the germination rate and initial stages of plant growth in common stress environments, such as drought, salinity, and low-temperature conditions. As a general result, it has been found that the germination rate was higher for plasma-treated than for untreated seeds. Plasma also induced favorable changes in plant and radicle dimensions, which depended on the environment. The obtained results demonstrate that plasma affects the biochemical metabolic chains of seeds and plants, resulting in changes in the concentration of biochemical growing factors, a faster germination, and an initially more robust plant growth, even under stress conditions. These changes in phenotype are accompanied by differences in the concentration of biomarkers such as photosynthetic pigments (chlorophylls a and b and carotenoids), reactive oxygen species, and, particularly, the amino acid proline in the leaves of young plants, with changes that depend on environmental conditions and the application of a plasma treatment. This supports the idea that, rather than an increase in seed water imbibition capacity, there are clear beneficial effects on seedling of plasma treatments.

An Exploratory Study Investigating the Prevalence of Gastrointestinal Symptoms in Collegiate Division I American Football Athletes.

Gastrointestinal (GI) symptoms may limit performance, but their prevalence and impact among team sports athletes is not well-documented. The objective of this study was to examine the prevalence of GI symptoms in a small sample of collegiate DI American football athletes, using a survey including the Gastrointestinal Symptoms Ratings Scale (GSRS). Forty-six athletes responded to the survey and reported scores for the 15-question GSRS with additional questions about dietary habits and supplement use. A total of 44 athletes were included in the study (45% of the current roster, age: 20.7 ± 1.7 years, 50% Afro-American or black, 39% skill position, 18% NSAIDs use, and 41% reporting protein supplement use); approximately half of the athletes (52%) reported experiencing GI complaints during exercise. Two-thirds of the athletes (61%) reported at least one or more GI symptoms in general, and 50% reported at least four moderate complaints. Seven athletes (16%) reported ≥2 severe GI symptoms with 5-13 moderate complaints. The most reported symptom was stomach pain (39%, n = 17), followed by hunger pain (36%, n = 16). Athletes reporting the use of protein supplements reported a higher GSRS score (22.0 and interquartile range (IQR) 17.0-31.8) vs. athletes not reporting protein use (15.0 and IQR 15.0-19.3), p = 0.001. Most athletes surveyed reported experiencing GI symptoms. A small group of these athletes reported multiple, varied, and severe symptoms that were associated with self-reported protein supplement use. In conclusion, the number of complaints varied among athletes, confirming the value of integrating the GSRS for screening purposes, and the expected need for individual dietary treatment approaches.

Bilateral Acute Iris Transillumination Associated with Moxifloxacin Antibiotic Use.

PURPOSE: To describe the clinical and demographic characteristics and associated factors leading to bilateral acute iris transillumination (BAIT) syndrome. METHODS: A retrospective review of patients with BAIT syndrome was performed. RESULTS: Thirty-five patients with a diagnosis of BAIT were identified. The median age at presentation was 53 years; 80% of the patients were female. Twenty-six patients (74%) had recent histories of systemic antibiotic treatment. Of those with such a history, 24 patients (92%) had been receiving moxifloxacin. Two patients within our cohort were prescribed moxifloxacin prophylactically prior to a systemic surgical procedure and had no evidence of systemic illness or recent viral illness. CONCLUSIONS: Our data support the notion that moxifloxacin might be associated with the onset of BAIT syndrome. Notably, within our cohort, two patients received moxifloxacin as surgical prophylaxis and subsequently developed BAIT syndrome. This could suggest a potential association between moxifloxacin and the onset of BAIT, though further studies are needed to confirm this finding.

Adjuvant Intravitreal Bevacizumab for Retinal Neovascularization in Eales' Disease Associated With Latent Mycobacterium Tuberculosis.

We report a case of bilateral Eales' disease managed with intravitreal bevacizumab. A 32-year-old woman with a history of bacillus Calmette-Guerin vaccine, administered when she was 10 years old, presented with a five-day history of a scotoma in the temporal field of her right eye. A dilated fundus exam and fluorescein angiography showed bilateral retinal peripheral capillary non-perfusion, retinal neovascularization in the right eye, and deep intraretinal hemorrhages in the left eye. Her laboratory workup resulted in a positive QuantiFERON-TB Gold test (Cellestis Ltd, Carnegie, Victoria, Australia). Chest computed tomography showed a calcified granuloma in her right lung. Angiographic-guided pan-retinal photocoagulation was performed, and intravitreal injections of bevacizumab (1.25 mg/0.05 mL) were administered in both eyes over the course of three months. The intraretinal hemorrhages resolved after three months of therapy. Three months following treatment, the patient showed normal fundus findings without any evidence of recurrence and a visual acuity of 20/20 in both eyes. Intravitreal bevacizumab in combination with angiography-guided pan-retinal photocoagulation may be efficacious in select patients with Eales' disease.

Vegetarian diets in Spain: Temporal evolution through national health surveys and their association with healthy lifestyles.

OBJECTIVE: To assess the prevalent consumption trend between 2001 and 2017 and the healthy lifestyles associated with consuming a plant-based diet in the Spanish population. METHODOLOGY: A representative Spanish sample was analysed (>15 years old) from the Spanish National Health Survey for years 2001 (n=8568), 2006 (n=25,649), 2011 (n=19,027) and 2017 (n=21,986). The population was classified as omnivore, vegetarian, or vegan. The lifestyle variables were physical activity, tobacco and alcohol consumption, and body mass index (BMI). The χ2 test was used to evaluate diet change between 2001 and 2017. T-Student and χ2 were used to compare lifestyles of omnivores and vegetarians/vegans. Logistic regression was used to analyse lifestyles associated with plant-based diets. RESULTS: 0.2% of the Spanish population followed a plant-based diet. Between plant-based diet consumers there was an increase in vegans vs. vegetarians between 2001 (9.5% vs. 90.5%) and 2017 (65.3% vs. 34.7%) (p=0.007). Compared to 2001, following a plant-based diet was more likely in 2006 (OR=2.08, p=0.004), 2011 (OR=1.89, p=0.02) and 2017 (OR=1.75, p=0.04). Those who consume alcohol (OR=0.65, p=0.008), who were overweight (OR=0.48, p<0.001) or who were obese (OR=0.40, p=0.001) were less likely to consume a plant-based diet. CONCLUSIONS: Despite an increase in the consumption of plant-based diets between 2001 and 2017, there was a low prevalence of consumption in all years studied. There was a greater probability of consuming plant-based diets among the Spanish population with healthy behaviours. These findings could help design strategies focused on healthy nutritional behaviours.

Long range gene flow beyond predictions from oceanographic transport in a tropical marine foundation species.

The transport of passively dispersed organisms across tropical margins remains poorly understood. Hypotheses of oceanographic transportation potential lack testing with large scale empirical data. To address this gap, we used the seagrass species, Halodule wrightii, which is unique in spanning the entire tropical Atlantic. We tested the hypothesis that genetic differentiation estimated across its large-scale biogeographic range can be predicted by simulated oceanographic transport. The alternative hypothesis posits that dispersal is independent of ocean currents, such as transport by grazers. We compared empirical genetic estimates and modelled predictions of dispersal along the distribution of H. wrightii. We genotyped eight microsatellite loci on 19 populations distributed across Atlantic Africa, Gulf of Mexico, Caribbean, Brazil and developed a biophysical model with high-resolution ocean currents. Genetic data revealed low gene flow and highest differentiation between (1) the Gulf of Mexico and two other regions: (2) Caribbean-Brazil and (3) Atlantic Africa. These two were more genetically similar despite separation by an ocean. The biophysical model indicated low or no probability of passive dispersal among populations and did not match the empirical genetic data. The results support the alternative hypothesis of a role for active dispersal vectors like grazers.

Lathyrus sativus Resistance Against the Existing and Emerging Pathogens Erysiphe pisi and E. trifolii: A Case of Commonalities or Total Discrepancy?

Powdery mildew on Lathyrus sativus (grass pea) is commonly caused by Erysiphe pisi, the causal agent of pea powdery mildew. E. trifolii could also pose an additional threat to grass pea, as it does to pea (Pisum sativum). In order to understand the potential threat and the availability of resistance sources, the response to both pathogens was analyzed on a worldwide germplasm collection of 189 grass pea accessions. Infection type and disease severity (DS) of grass pea accessions, independently inoculated with E. pisi and E. trifolii, were evaluated under controlled conditions. A wide range of responses were detected, with the previously uncharacterized partial resistance to E. trifolii in grass pea detected less frequently and uncorrelated with partial resistance against E. pisi. To test for the lack of correlation at the genetic level, an exploratory association mapping study was undertaken by statistically combining grass pea collection DS scores against both pathogens, with 5,651 previously screened genotype-by-sequencing-based single nucleotide polymorphisms (SNP). Mostly different genetic regions in grass pea were identified as being associated with the response to E. trifolii and E. pisi, anticipating an independent genetic basis that requires further validation in larger germplasm collections, with higher SNP densities. This study proposes common and unique partial resistance components against two different powdery mildews, implying the need for complementary approaches to introduce resistance to both pathogens into new grass pea varieties. The identified sources of resistance and predicted genomic targets will assist in breeding for resistance to multiple powdery mildews.

Development of core competencies for field veterinary epidemiology training programs.

A workforce with the adequate field epidemiology knowledge, skills and abilities is the foundation of a strong and effective animal health system. Field epidemiology training is conducted in several countries to meet the increased global demand for such a workforce. However, core competencies for field veterinary epidemiology have not been identified and agreed upon globally, leading to the development of different training curricula. Having a set of agreed core competencies can harmonize field veterinary epidemiology training. The Food and Agriculture Organization of the United Nations (FAO) initiated a collective, iterative, and participative process to achieve this and organized two expert consultative workshops in 2018 to develop core competencies for field veterinary epidemiology at the frontline and intermediate levels. Based on these expert discussions, 13 competencies were identified for the frontline and intermediate levels. These competencies were organized into three domains: epidemiological surveillance and studies; field investigation, preparedness and response; and One Health, communication, ethics and professionalism. These competencies can be used to facilitate the development of field epidemiology training curricula for veterinarians, adapted to country training needs, or customized for training other close disciplines. The competencies can also be useful for mentors and employers to monitor and evaluate the progress of their mentees, or to guide the selection process during the recruitment of new staff.

Systemic Disease Associations in a Cohort of Hispanic Patients with Scleritis.

(1) Purpose: A patient with scleritis may have an associated systemic disease, which is often autoimmunological and seldom infectious in origin. The data regarding such associations in Hispanic populations are scarce. Therefore, we evaluated the clinical characteristics and systemic-disease associations of a cohort of Hispanic patients with scleritis. (2) Methods: A retrospective review of the medical records (January 1990-July 2021) of two private uveitis practices in Puerto Rico was performed. Clinical characteristics and systemic-disease associations observed either at presentation or diagnosed as a consequence of the initial workup were recorded. (3) Results: A total of 178 eyes of 141 patients diagnosed with scleritis were identified. An associated autoimmune disease was present in 33.3% of the patients (rheumatoid arthritis, 22.7%; Sjögren's syndrome, 3.5%; relapsing polychondritis, 2.8%; sarcoidosis, 1.4%; systemic lupus erythematosus, 1.4%; and systemic vasculitis, 0.7%). An associated infectious disease was present in 5.7% of the patients (2.13%, syphilis; 1.41%, herpes simplex; 1.14%, herpes zoster; and 0.71%, Lyme disease). One patient had all-trans retinoic-acid-associated scleritis. Statistical analysis revealed that patients with nodular anterior scleritis were less likely to have an associated immune-mediated disease (OR: 0.21; p = 0.011). (4) Conclusion: Rheumatoid arthritis was the most common systemic autoimmune disease association, while syphilis was the most common infectious disease associated with scleritis patients. Our study suggests that patients with nodular scleritis have a lower risk of having an associated immune-mediated disease.
