[PMID: 38195832 PMCID: PMC10776542 DOI: 10.1186/s11671-023-03932-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 11/27/2023] [Indexed: 01/11/2024]
Abstract
This review paper highlights the trans-dermic delivery of nanoparticles (NPs) based antifungal ointments with the help of nanotechnology. It also describes the novel trans-dermal approach utilizing various nanoparticles which enables an efficient delivery to the target site. This current review gives an overview about past research and developments as well as the current nanoparticle-based ointments. This review also presents data regarding types, causes of infection, and different pathogens within their infection site. It also gives information about antifungal ointments with their activity and side effects of antifungal medicines. Additionally, this review also focuses on the future aspects of the topical administration of nanoparticle-based antifungal ointments. These nanoparticles can encapsulate multiple antifungal drugs as a combination therapy targeting different aspects of fungal infection. Nanoparticles can be designed in such a way that they can specifically target fungal cells and do not affect healthy cells. Nanoparticle based antifungal ointments exhibit outstanding potential to treat fungal diseases. As further research and advancements evolve in nanotechnology, we expect more development of nanoparticle-based antifungal formulations shortly. This paper discusses all the past and future applications, recent trends, and developments in the various field and also shows its bright prospective in the upcoming years.

Abstract
Microbial pathogens, including bacteria, fungi and viruses, greatly threaten the global public health. For pathogen infections, early diagnosis and precise treatment are essential to cut the mortality rate. The emergence of aggregation-induced emission (AIE) biomaterials provides an effective and promising tool for the theranostics of pathogen infections. In this review, the recent advances about AIE biomaterials for anti-pathogen theranostics are summarized. With the excellent sensitivity and photostability, AIE biomaterials have been widely applied for precise diagnosis of pathogens. Besides, different types of anti-pathogen methods based on AIE biomaterials will be presented in detail, including chemotherapy and phototherapy. Finally, the existing deficiencies and future development of AIE biomaterials for anti-pathogen applications will be discussed.

What Is Candida Doing in My Food? A Review and Safety Alert on Its Use as Starter Cultures in Fermented Foods. Microorganisms 2022; 10:microorganisms10091855. [PMID: 36144457 PMCID: PMC9502980 DOI: 10.3390/microorganisms10091855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 09/02/2022] [Accepted: 09/07/2022] [Indexed: 12/02/2022] Open
Abstract
The use of yeasts as starter cultures was boosted with the emergence of large-scale fermentations in the 20th century. Since then, Saccharomyces cerevisiae has been the most common and widely used microorganism in the food industry. However, Candida species have also been used as an adjuvant in cheese production or as starters for coffee, cocoa, vegetable, meat, beer, and wine fermentations. A thorough screening of candidate Candida is sometimes performed to obtain the best performing strains to enhance specific features. Some commonly selected species include C. pulcherrima (teleomorph Metschnikowia pulcherrima) (wine), C. parapsilosis (teleomorph Monilia parapsilosis) (coffee), C. famata (teleomorph Debaryomyces hansenii) (cheese), and C. zeylanoides (teleomorph Kurtzmaniella zeylanoides) and C. norvegensis (teleomorph Pichia norvegensis) (cocoa). These species are associated with the production of key metabolites (food aroma formation) and different enzymes. However, safety-associated selection criteria are often neglected. It is widely known that some Candida species are opportunistic human pathogens, with important clinical relevance. Here, the physiology and metabolism of Candida species are addressed, initially emphasizing their clinical aspects and potential pathogenicity. Then, Candida species used in food fermentations and their functional roles are reported. We recommended that Candida not be used as food cultures if safety assessments are not performed. Some safety features are highlighted to help researchers choose methods and selection criteria.

Abstract
Purpose of Review The increase in international travel in recent decades has contributed to the risk of acquiring diseases considered endemic to a region or country and the change in the epidemiology of these diseases. Endemic mycoses that may be acquired by travelers in the short or long term are endemic subcutaneous mycoses such as sporotrichosis and lobomycosis, while endemic systemic mycoses are a group of serious diseases including histoplasmosis and coccidioidomycosis. Herein, we review the current knowledge and highlight the most important aspects of these fungal infections in travelers. Recent Findings The most relevant advances in the study of these mycoses involve the epidemiological distribution; human mycoses can be fatal and there are few antifungal drugs available, increasing drug resistance, and a risk of emerging fungal diseases associated with climate change, as well as the increasing virulence, and the diagnostic strategies that may be limited in many countries. Summary Although endemic mycoses are relatively rare, they should be considered as potentially travel-related illnesses. A recent or late trip to an endemic country may guide the clinical suspicion, an early diagnosis, and the institution of effective therapy.

Abstract
The prevalence of skin disease varies with geographic location and may be affected by cultural factors. In Haiti, the combination of poor health care access, infrastructure lack, and natural disasters may affect the prevalence of skin conditions. Unfortunately, little epidemiological information has been obtained on the prevalence of skin diseases in Haiti. The objective of this study is to describe data on the prevalence of dermatological conditions in urban areas of Haiti. Univariate, bivariate, and χ2 analyses were used to evaluate associations. During February 2016, we documented 137 patients. The mean age was 27.7 years; most of the subjects were women (61.3%) in a cohort mostly adult (67.1%). The infectious and inflammatory dermatoses were the most prevalent (74.2%). Infectious skin diseases were more prevalent in men and in adults in general (p < 0.01). Inflammatory conditions were also more common in adults (p < 0.05). Additionally, alopecia and dyschromia were limited to women (p < 0.01). Infectious skin diseases, in particular fungal infections, were amongst the most common diagnoses in the urban area of Haiti. Therefore, improved access to antimicrobial and anti-inflammatory medications would likely benefit Haitian patients with dermatological conditions. These findings may help local public health officials and future dermatological expeditions better serve this population.

Abstract
Helianthus species are North American members of the Asteraceae, several of which have been used as traditional medicines by Native Americans. The aerial parts of two cultivars of Helianthus annuus, “Chianti” and “Mammoth”, and wild-growing H. strumosus, were collected from locations in north Alabama. The essential oils were obtained by hydrodistillation and analyzed by gas chromatography—mass spectrometry. The Helianthus essential oils were dominated by monoterpene hydrocarbons, in particular α-pinene (50.65%, 48.91%, and 58.65%, respectively), sabinene (6.81%, 17.01%, and 1.91%, respectively), β-pinene (5.79%, 3.27%, and 4.52%, respectively), and limonene (7.2%, 7.1%, and 3.8%, respectively). The essential oils were screened against three opportunistic pathogenic fungal species, Aspergillus niger, Candida albicans, and Cryptococcus neoformans. The most sensitive fungus was C. neoformans with minimum inhibitory concentration (MIC) values of 78, 156, and 78 μg/mL, respectively.

Abstract
The plant Lepechinia mutica (Benth.) Epling (family Lamiaceae) is endemic to Ecuador. In the present study, we report some major non-volatile secondary metabolites from the leaves and the chemistry of the essential oil distilled from the flowers. The main identified compounds were carnosol, viridiflorol, ursolic acid, oleanolic acid, chrysothol, and 5-hydroxy-4′,7-dimethoxy flavone. Their structures were determined by X-ray diffraction and NMR and MS techniques. The essential oil showed a chemical composition similar to that distilled from the leaves, but with some qualitative and quantitative differences regarding several minor compounds. The main constituents (>4%) were: δ-3-carene (24.23%), eudesm-7(11)-en-4-ol (13.02%), thujopsan-2-α-ol (11.90%), β-pinene (7.96%), valerianol (5.19%), and co-eluting limonene and β-phellandrene (4.47%). The volatile fraction was also submitted to enantioselective analysis on a β-cyclodextrin column, obtaining the separation and identification of the enantiomers for α-thujene, β-pinene, sabinene, α-phellandrene, limonene and β-phellandrene. Furthermore, the anti-fungal activity of non-volatile secondary metabolites was tested in vitro, with carnosol resulting in being very active against the “blast disease” caused by the fungus Pyricularia oryzae.

Abstract
Because of travel and migration patterns, tropical skin diseases are now seen all around the world, not just in tropical or developing countries. Nutrition, housing, and environmental factors play an important role in these infectious diseases, so when they appear out of their normal environments, their classic presentation may vary. Tropical diseases can also present differently in childhood, making their recognition, diagnosis, and management a clinical challenge. Health care providers in developed countries need to be familiar with tropical skin diseases and be able to diagnose them in returning travelers or immigrants in order to optimize care. This article aims to review the epidemiologic, clinical, diagnostic, and therapeutic aspects of some of the most common tropical dermatologic conditions in children.

Abstract
AIMS We determined the chemical composition and investigated the antifungal activity of Otacanthus azureus (Linden) Ronse essential oil (EO) against a range of dermatophytes alone or in combination with azole antifungals. METHODS AND RESULTS Aerial parts of the plant were steam-distilled and the obtained oil was analysed by gas chromatography/mass spectrometry and (1) H-NMR. It was shown to be largely composed of sesquiterpenes, with the main component being β-copaen-4-α-ol. Using broth microdilution techniques, this oil was found to have remarkable in vitro antifungal activities. Minimum inhibitory concentrations as low as 4 μg ml(-1) were recorded. The analysis of the combined effect of the O. azureus EO with azoles using chequerboard assays revealed a synergism between the EO and ketoconazole, fluconazole or itraconazole against Trichophyton mentagrophytes. Notably, the O. azureus essential oil showed low cytotoxicity to VERO cells. CONCLUSIONS The O. azureus essential oil alone or in combination with azoles is a promising antifungal agent in the treatment for human dermatomycoses caused by filamentous fungi. SIGNIFICANCE AND IMPACT OF THE STUDY There is much interest in the study of essential oils for the discovery of new antimicrobial drugs. This study has highlighted the antidermatophytic activity of the O. azureus EO.

Abstract
Defense mutualisms between social insects and microorganisms have been described in the literature. The present article describes the discovery of a Pseudallescheria boydii strain isolated from Nasutitermes sp. The microbial symbiont produces two antifungal metabolites: tyroscherin and N-methyltyroscherin, a compound not previously described in the literature. Methylation of tyroscherin has confirmed the structure of N-methyltyroscherin. Both compounds are effective antifungal agents with favorable selectivity indices for Candida albicans and Trichophyton rubrum.

Abstract
Yeasts have a tradition in biotechnological applications, and Saccharomyces species are the most dominating representatives. Among the yeast species, Candida krusei has been isolated from different habitats, and in recent years, it has gained increased interest because of its diverse biotechnological role. It is found in many fermented food items and dairy products and has also been exploited for production of biochemicals and enzymes. However, because of its opportunistic pathogenic nature, it draws scientific attention regarding the safety of its industrial exploitation. Candida krusei generally causes infections in immunocompromised patients, such as those suffering from Human immunodeficiency virus - acquired immune deficiency syndrome, and also in cancer patients. The recent increase in the use of immunosuppressive drugs has increased the chances of C. krusei infections. Candida krusei possesses an intrinsic resistance to many triazole antifungal drugs, especially fluconazole, which is a main drug used in antifungal therapy; therefore, there is serious concern regarding its safe industrial use.

Abstract
Research on antifungal compounds from the durable wood from French Guiana Amazonian forest trees highlights the correlation between the activity of their extracts against wood-rotting fungi and human pathogens. The fractionation of an ethyl acetate extract of Sextonia rubra wood led to the isolation of rubrenolide (1) and rubrynolide (2). The potential of compounds 1 and 2 is described through the evaluation of their activity against 16 pathogenic fungi and their cytotoxicity toward NIH-3T3 mammalian fibroblast cells.

Abstract
BACKGROUND Dermatologic diseases vary widely as a result of geographic location and may be influenced by environmental factors. Aim To determine the epidemiology of dermatological diseases in the Peruvian Amazonia. METHODS Transversal and multicentric study, which were carried out during February of 2006, 2007, and 2008 in three regional hospitals in the Peruvian Amazonia. All new patients who were looking for dermatological consultation were included. Univariate/bivariate analysis, chi square, and multinomial logistic regression were used with a confidence level of 95%. RESULTS A total of 1602 patients were included. The infectious and parasitic dermatoses were the most prevalent (31.5%). There was a statistically significant association between infections of the skin and subcutaneous tissue in children (P < 0.001). The parasitic dermatoses such as scabiosis, pediculosis, and myiasis were associated with an altitude less than 700 meters above sea level (m.a.s.l.) (P = 0.003, OR = 3.1, CI: 1.5-6.7). On the other hand, radiation-related disorders of the skin and subcutaneous tissue were associated with more than 700 m.a.s.l. (P < 0.01, OR = 2.9, CI: 1.7-4.9). CONCLUSIONS Infectious dermatological diseases were the most common diagnoses in the Peruvian Amazonia. In addition, radiation-related disorders of the skin should be addressed for people living/traveling in the rainforest area. These findings may assist in the training of general doctors in diagnosis and treatment of the most common dermatoses in tropical areas. Moreover, this study would be helpful for physicians from developed countries when giving medical advice/attention to travelers or immigrants of tropical areas.

Abstract
Imported tropical diseases are among the top three leading causes for morbidity and may affect up to 8% of returning travelers. Because the spectrum of dermatological manifestations seen in travelers is broad, it can be challenging for physicians to recognize and treat such conditions in a timely and efficient manner. Therefore, the present review highlights common imported tropical diseases with a focus on treatment regimens. Specifically, cutaneous larva migrans, myiasis, swimmer's itch, mycetoma, Chagas disease, and leishmaniasis are discussed. As awareness increases among travelers, immigrants, and health care providers regarding imported tropical diseases, early intervention and proper diagnosis can ensue, thus reducing morbidity and mortality in affected individuals.

Abstract
Overexpression of the ABC transporters Cdr1 and Cdr2 or the major facilitator Mdr1 causes multidrug resistance in the human fungal pathogen Candida albicans. The fatty acid synthesis inhibitor cerulenin and the structurally unrelated Golgi transport inhibitor brefeldin A are substrates for both types of efflux pumps in Candida albicans. In an effort to overcome efflux pump-mediated drug resistance in Candida albicans, cerulenin analogues were generated using a variety of synthesis pathways. The so obtained cerulenin derivatives were tested on multidrug-resistant Candida albicans isolates which constitutively overexpress either Mdr1 or Cdr1 and Cdr2. Some of these compounds were found to decrease Mdr1-mediated resistance to brefeldin A up to eightfold compared to the control.
