Cutaneous Hyalohyphomycosis and Its Atypical Clinical Presentations in Immunosuppressed Patients.

There has been a substantial increase in the number of cases of invasive fungal infections worldwide, which is associated with a growing number of immunosuppressed patients and a rise in antifungal resistance. Some fungi that were previously considered harmless to humans have become emerging pathogens. One of them is Purpureocillium lilacinum, a ubiquitous filamentous fungus commonly found in the environment, especially in the air and soil. P. lilacinum belongs to a bigger group of hyaline fungi that cause hyalohyphomycosis, a fungal infection caused by fungi with colorless hyphae. Although this is a heterogeneous group of fungi, there are similarities regarding their ubiquity, ways of transmission, affected patients, and difficulties in diagnostics and treatment. In hyalohyphomycosis, the skin is one of the most affected organs, which is why the involvement of dermatologists is crucial for the initial assessment, since the timely recognition and early diagnosis of this condition can prevent life-threatening infections and death. In this review, we covered cutaneous hyalohyphomycosis caused by P. lilacinum and other fungi in the same group, including Fusarium, Penicilium, Scedosporium, Scopulariopsis, Acremonium, and Trichoderma genera.

The Effect of a High-Protein Diet Supplemented with Blackthorn Flower Extract on Polyphenol Bioavailability and Antioxidant Status in the Organs of C57BL/6 Mice.

The health benefits of polyphenols are based on their bioavailability, which is why a significant portion of research focuses on factors that affect their bioavailability. Previous studies suggest that the intake of polyphenols along with macronutrients in food represents one of the key factors influencing the bioavailability of polyphenols and, consequently, their biological activity in the organism. Since polyphenols in the human diet are mainly consumed in food together with macronutrients, this study investigated the in vivo absorption, metabolism, and distribution of polyphenolic compounds from the water extract of blackthorn flower (Prunus spinosa L.) in combination with a protein-enriched diet in the organs (small intestine, liver, kidney) of C57BL/6 mice. The bioaccumulation of polyphenol molecules, biologically available maximum concentrations of individual groups of polyphenol molecules, and their effect on the oxidative/antioxidative status of organs were also examined. The results of this study indicate increased bioabsorption and bioavailability of flavan-3-ols (EC, EGCG) and reduced absorption kinetics of certain polyphenols from the groups of flavonols, flavones, and phenolic acids in the organs of C57BL/6 mice after intragastric administration of the water extract of blackthorn flower (Prunus spinosa L.) in combination with a diet enriched with whey proteins. Furthermore, subchronic intake of polyphenols from the water extract of blackthorn flower (Prunus spinosa L.) in combination with a diet enriched with whey proteins induces the synthesis of total glutathione (tGSH) in the liver and superoxide dismutase (SOD) in the liver and small intestine. The results of this study suggest potential applications in the development of functional foods aimed at achieving the optimal health status of the organism and the possibility of reducing the risk of oxidative stress-related disease.

Increased Scabies Incidence at the Beginning of the 21st Century: What Do Reports from Europe and the World Show?

Reports from various countries have described increasing numbers of scabies cases, especially in the past two decades. The epidemiological data for various world regions showed prevalence estimates ranging from 0.2% to 71%, with the highest prevalence in the Pacific region and Latin America. Therefore, geographically, scabies occurs more commonly in the developing world, tropical climates, and in areas with a lack of access to water. According to results from specific regions of the world, the greatest burdens from scabies were recorded for East Asia, Southeast Asia, Oceania, tropical Latin America, and South Asia. Among countries with the highest rates, the top 10 were Indonesia, China, Timor-Leste, Vanuatu, Fiji, Cambodia, Laos, Myanmar, Vietnam, and the Seychelles. From Europe, available data shows an increasing trend in scabies infestation, particularly evident among populations with associated contributing factors, such as those who travel frequently, refugees, asylum seekers, those who regularly lack drinking water and appropriate hygiene and are of a younger age, etc. This increase in observed cases in the last 10-20 years has been evidenced by research conducted in Germany, France, Norway, and Croatia, among other countries. In addition, increased scabies transmission was also recorded during the COVID-19 pandemic and may have been the result of increased sexual intercourse during that time. Despite all the available treatment options, scabies commonly goes unrecognized and is therefore not treated accordingly. This trend calls for a prompt and synergistic reaction from all healthcare professionals, governmental institutions, and non-governmental organizations, especially in settings where population migration is common and where living standards are low. Furthermore, the proper education of whole populations and accessible healthcare are cornerstones of outbreak prevention. Accurate national data and proper disease reporting should be a goal for every country worldwide when developing strategic plans for preventing and controlling the community spread of scabies.

ABO blood group genotypes and ventilatory dysfunction in patients with allergic and nonallergic asthma.

Aim ABO blood group genotypes are established as a genetic factor in pathophysiology of various diseases, such as cardiovascular disorders, cancers, infectious diseases and there is rising evidence of their involvement in other conditions. The aim of this study was to determine if ventilatory changes of lung function in asthma, measured by biomarkers/parameters, are connected to certain ABO blood group genotypes in Croatia. Methods A case-control study included 149 patients with asthma and 153 healthy individuals (blood donors). ABO genotyping on five main alleles was performed using PCR-SSP method. All patients had spirometry performed and severity of asthma was estimated. Clinical parameters of spirometry (FEV1, FEV/FVC, PEF), biomarkers FeNO, IgE and pO2 were measured. The χ2 test, Fisher's test, Kruskal-Wallis test and Spearman's correlation coefficients with p<0.05 were used as statistically significant. Results There was no determined statistically significant difference in both ABO genotypes and phenotypes between patient and control groups. Comparison of the lung function in different ABO phenotypes in asthmatic patients also did not show any statistically significant differences in FEV1 values, FEV/FVC ratio or PEF. Statistically significant differences in oxygenation between different ABO blood types have not been noticed (p=0.326). Differences in quantitative values of biomarkers (FeNO and IgE) between different ABO blood phenotypes in patients with asthma were not significant, except for IgE that had marginal values (p=0.074). Conclusion No correlation was found between certain ABO blood group genotypes and parameters/biomarkers of ventilatory dysfunction in patients with allergic and nonallergic asthma.

Gender Differences in Relationship between Body Mass Index and Asthma.

BACKGROUND: Asthma is one of the most common chronic diseases in the world. Obesity is the most common comorbidity of asthma and is connected to incidence and course of the disease. Obesity is associated with non-allergic asthma phenotype, but this relation could be influenced by gender. The aim of our study was to determine the relationship between BMI and asthma and to explore possible gender differences. SUBJECTS AND METHODS: Study included 149 patients with asthma (examined group) and 153 healthy blood donors (control group). Data from the medical records of patients with asthma were used, and all included subjects had their BMI calculated using standard formula. Data were analyzed using descriptive statistics methods. Data with non-parametric distribution were analysed with Mann-Whitney U test and showed through medians with corresponding interquartile ranges. Statistical significance of BMI differences between non-allergic asthma, allergic asthma and control groups were analyzed by one-way analysis of variance - ANOVA. The results were interpreted at a significance level of P<0.05. RESULTS: The comparison between median BMI values of two groups shows that examined group of patients with astma has significantly higher median BMI value in comparison with control group (P=0.035). Correlation was stronger for women than men (P=0.002 vs P=0.898). Incresed BMI of the examined group of patients with asthma was not asociated with non-allergic asthma (P=0.085). However, when stratified according to gender, there was a strong association of increased BMI with non-allergic asthma in women (P<0.001). CONCLUSION: Patients with asthma in our study have higher BMI in comparison to healthy individuals, which contributes to hypothesis that BMI is a risk factor for development of asthma. We found that possible effect that BMI has on asthma is stronger in women, since there was a strong association between increased BMI and non-allergic asthma only in women.

The Role of Pai-1 Gene 4g/5g Polymorphism and Diagnostic Value of Biomarkers in Allergic and Non-Allergic Asthma Phenotype.

Asthma is a chronic inflammatory disease that is characterized by reversible obstruction of airways, bronchial hyper-reactivity and airway remodeling. The etiology of asthma is multifactorial, with inheritance playing an important role. The aim of our study was to investigate the importance of biomarkers of asthma and the role of plasminogen activator inhibitor-1 (PAI-1) gene as a genetic factor that could be involved in the pathogenesis of asthma. The research was conducted at Jordanovac University Department for Lung Diseases and Croatian Institute of Transfusion Medicine. The research included 149 patients with asthma and 89 healthy individuals. We collected demographic data of both study groups, determined asthma severity using GINA guidelines, and the values of biomarkers and PAI-1 by using laboratory techniques. Based on the results, we concluded that patients with allergic phenotype of asthma were younger, had better lung function and higher levels of IgE. By observing FeNO values, we were not able to distinguish asthmatic patients that had been diagnosed with obstruction of airways from asthmatic patients with normal lung function because FeNO indicates the inflammatory component of disease. The 4G/5G polymorphism of PAI-1 gene did not show any statistically significant difference in the distribution of 4G/4G, 4G/5G and 5G/5G between the group of asthmatic patients and control group.
