Recognizing the growing global burden of fungal infections, the World Health Organization established a process to develop a priority list of fungal pathogens (FPPL). In this systematic review, we aimed to evaluate the epidemiology and impact of infections caused by Fusarium spp., Scedosporium spp., and Lomentospora prolificans to inform the first FPPL. PubMed and Web of Sciences databases were searched to identify studies published between January 1, 2011 and February 23, 2021, reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 20, 11, and 9 articles were included for Fusarium spp., Scedosporium spp., and L. prolificans, respectively. Mortality rates were high in those with invasive fusariosis, scedosporiosis, and lomentosporiosis (42.9%-66.7%, 42.4%-46.9%, and 50.0%-71.4%, respectively). Antifungal susceptibility data, based on small isolate numbers, showed high minimum inhibitory concentrations (MIC)/minimum effective concentrations for most currently available antifungal agents. The median/mode MIC for itraconazole and isavuconazole were ≥16 mg/l for all three pathogens. Based on limited data, these fungi are emerging. Invasive fusariosis increased from 0.08 cases/100 000 admissions to 0.22 cases/100 000 admissions over the time periods of 2000-2009 and 2010-2015, respectively, and in lung transplant recipients, Scedosporium spp. and L. prolificans were only detected from 2014 onwards. Global surveillance to better delineate antifungal susceptibility, risk factors, sequelae, and outcomes is required.

Meta-Analysis Review
The aim of this study was to perform a systematic review of the literature followed by a meta-analysis about the efficacy of photodynamic therapy (PDT) on the microorganisms responsible for dental caries. The research question and the keywords were constructed according to the PICO strategy. The article search was done in Embase, Lilacs, Scielo, Medline, Scopus, Cochrane Library, Web of Science, Science Direct, and Pubmed databases. Randomized clinical trials and in vitro studies were selected in the review. The study was conducted according the PRISMA guideline for systematic review. A total of 34 articles were included in the qualitative analysis and four articles were divided into two subgroups to perform the meta-analysis. Few studies have achieved an effective microbial reduction in microorganisms associated with the pathogenesis of dental caries. The results highlight that there is no consensus about the study protocols for PDT against cariogenic microorganisms, although the results showed the PDT could be a good alternative for the treatment of dental caries.

Meta-Analysis Review
BACKGROUND
Increased hospitalisation rates in the Coronavirus disease 19 (COVID-19) era lead to a new wave of hospital-acquired infections such as emerging multidrug-resistant Candida auris. We aimed to evaluate and estimate the global prevalence of coronavirus-associated C. auris infection (CACa).
METHODS
We searched related databases between December 2019 and April 2022 for studies that reported data about CACa. Meta-analysis was performed using MedCalc software version 20.104 according to the DerSimonian and Laird method applying the random-effects model. We evaluated heterogeneity using the χ -based Q statistic (significant for p-value < .1) and the I statistic (>75% indicative of 'notable' heterogeneity). Moreover, if possible, an odds ratio (OR) analysis was performed for eligible data.
RESULTS
Our meta-analysis includes ten eligible studies, including 1942 patients hospitalised with COVID-19; 129 were C. auris cases. The overall pooled prevalence of CACa was estimated at 5.7%. The mortality rate of CACa was estimated at 67.849%. Hypertension was the most prevalent comorbidity (59.374%), followed by diabetes mellitus (52.898%) and cardiovascular diseases (31.392%). Men with a prevalence rate of 80.012% were 3.27 (OR) times more prone to getting infected by C. auris.
CONCLUSION
We concluded that the prevalence of C. auris infections decreased during the COVID-19 pandemic and the prevalence gradient changed from Asia to America. Unfortunately, there are many descriptive studies with duplicate content in the field of epidemiology of C. auris infections which are increasing every day. We suggest further non-descriptive studies to accurately establish the cause-and-effect relationships between C. auris and COVID-19 infections.

Meta-Analysis
OBJECTIVES
Candidaemia is a serious hazard to hospitalized patients, but European epidemiological data are restricted to national studies focusing on Northern Europe, population-based surveillance programmes or studies conducted in distinct local areas. The aim was to provide current data on the overall burden and epidemiological development of candidaemia in Europe.
METHODS
A Web of Knowledge™ search was carried out from January 2000 to February 2019. Appropriate data were collected on total cases, study duration, incidence, species distribution and/or mortality rates. Meta-analysis was performed to pool individual studies. Heterogeneity was examined using the I statistic. Calculations of pooled incidence and mortality rates, subgroup analysis by geographical origin, study period and scenarios were carried out. Daily candidaemia incidence and mortality rates in Europe were extrapolated. Systematic review and meta-analysis were used to determine incidence and mortality of candidaemia in the UN European region. Complete datasets were categorized into population-based and hospital-based epidemiological studies and were analysed separately. Subgroup analyses were performed for geographic distributions and time-dependent developments.
RESULTS
In population-based studies, 43 799 cases of candidaemia were diagnosed in 1 885 271 885 person-years, revealing an overall pooled incidence rate of 3.88/100 000. The highest pooled incidence rate was observed in intensive care units (5.5/1000 admissions, Day 30 mortality rate 37%), followed by tertiary care centres (0.96/1000 admissions, pooled Day 30 mortality rate 38%) and the mixed group of teaching and general hospitals (0.52/1000 admissions, pooled Day 30 mortality rate 37%). European incidence of candidaemia was extrapolated to approximately 79 cases per day, of which an estimated 29 patients might have fatal outcome at Day 30.
CONCLUSIONS
Pooled incidence rates, species distribution and outcome of candidaemia differ considerably between clinical groups, European regions and over time. We observed an increasing overall pooled incidence rate of candidaemia and a higher proportion of Candida spp. other than C. albicans in the current decade in population-based data.

Review
BACKGROUND AND PURPOSE
infections have increased significantly in the antimicrobial resistance era, and synthetic antifungal drugs have limitations. The present work aimed to review the antifungal properties of () as an herbal remedy.
METHOD
PubMed, Scopus, ScienceDirect, Web of Science, SID, Civilica, and Magiran databases were searched for the antifungal activity on , , dental biofilm, and clinical studies of on species.
RESULTS
Overall, 33 articles evaluated the effect of on species and classified them into four groups, as follows in vitro (23), dental biofilm (6), in vivo (2), and clinical studies (3). All studies considered effective in reducing or even inhibiting the growth of species. NoMFC significant differences were seen in the effect of on susceptible compared to the resistant groups of in the studies. It was also influential in inhibiting and .
CONCLUSION
Considering the side effects and resistance of current antifungal drugs as well as the benefits of using herbal medicines, such as lower cost, less likely to develop drug resistance, the absence of side effects, and toxicity compared with chemical ones it is possible as a powerful alternative to replace or combine with the current antifungal for infection therapy along with other therapies.

Meta-Analysis
BACKGROUND
Candida auris is a new pathogen called "superbug fungus" which caused panic worldwide. There are no large-scale epidemiology studies by now, therefore a systematic review and meta-analysis was undertaken to determine the epidemic situation, drug resistance patterns and mortality of C. auris.
METHODS
We systematically searched studies on the clinical report of Candida auris in Pubmed, Embase and Cochrane databases until October 6, 2019. A standardized form was used for data collection, and then statics was performed with STATA11.0.
RESULTS
It showed that more than 4733 cases of C. auris were reported in over 33 countries, with more cases in South Africa, United States of America, India, Spain, United Kingdom, South Korea, Colombia and Pakistan. C. auirs exhibited a decrease in case count after 2016. Clade I and III were the most prevalent clades with more cases reported and wider geographical distribution. Blood stream infection was observed in 32% of the cases, which varied depending on the clades. Resistance to fluconazole, amphotericin B, caspofungin, micafungin and anidulafungin in C. auris were 91, 12, 12.1, 0.8 and 1.1%. The overall mortality of C. auris infection was 39%. Furthermore, subgroup analyses showed that mortality was higher in bloodstream infections (45%), and lower in Europe (20%).
CONCLUSIONS
Over 4000 cases of C. auris were reported in at least 33 countries, which showed high resistance to fluconazole, moderate resistance to amphotericin B and caspofungin, high sensitivity to micafungin and anidulafungin. The crude mortality for BSI of C. auris was 45% which was similar to some drug-resistant bacteria previously reported. In conclusion, C. auris displayed similar characteristics to some drug resistance organisms. This study depicts several issues of C. auris that are most concerned, and is of great significance for the clinical management.

Meta-Analysis Review
Cryptococcosis is a common opportunistic infection associated with HIV/AIDS. The present review systematically describes the clinical and biological aspects of cryptococcosis in the Democratic Republic of Congo (DRC) and estimates its 2020 burden in people living with HIV (PLHIV). Following PRISMA guidelines, we searched online databases for records of cryptococcosis/Cryptococcus spp. in the DRC. Meta-analysis was then performed to estimate summary statistics and the corresponding 95% confidence intervals (CI). A total of 30 studies were included. These included 1,018 cryptococcosis patients, including 80.8% with neuromeningeal cryptococcosis (NMC) and predominantly immunocompromised due to HIV/AIDS (97.6%). The NMC mean prevalence was estimated at 9.63% (95% CI: 5.99-14.07). More than one in two patients (52.7%) under treatment died. Monotherapy with fluconazole was the main treatment administered (80.6%). Furthermore, we estimate that about 9,265 (95% CI: 5,763-13,537) PLHIV had cryptococcosis in 2020, in DRC; of which about 4,883 (95% CI: 3,037-7,134) would have died in the same year. Among isolates in all included studies, 74 strains have been characterised. Of these, 82.4% concerned Cryptococcus neoformans sensu lato (s.l) (exclusively of serotype A and mostly of molecular types VNI and VNII) and 17.6% concerned Cryptotoccus gattii s.l (belonging to serotype B/molecular type VGI). Cryptococcosis remains common with an unacceptably high mortality rate. A large number of PLHIV affected by and dying from cryptococcosis in 2020 demonstrates its heavy burden among the Congolese PLHIV. To mitigate this burden, it is important to improve the quality and accessibility of care for all PLHIV.

Review
infections are related to biofilm formation. The increase in antifungal resistance and their adverse effects have led to the search for therapeutic options as plant derivatives. This scoping review aims to identify the current status of in vitro research on the cytotoxicity and inhibitory effects of plant derivatives on biofilms. In this study, PRISMA items were followed. After recognition of the inclusion criteria, full texts were read and disagreements were resolved with a third party. A risk of bias assessment was performed, and information was summarized using Microsoft Office Excel. Thirty-nine papers fulfilling the selection criteria were included. The risk of bias analysis identified most of the studies as low risk. Studies evaluated plant derivatives such as extracts, essential oils, terpenes, alkaloids, flavonoids and polyphenols. Some studies evaluated the inhibition of biofilm formation, inhibition on preformed biofilms or both. The derivatives at concentrations greater than or equal to those that have an inhibitory effect on biofilms, without showing cytotoxicity, include magnoflorin, ellagic acid, myricetin and eucarobustol from and, as the works in which these derivatives were studied are of good quality, it is desirable to carry out study in other experimental phases, with methodologies that generate comparable information.

The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal pathogen priority list. This systematic review aimed to evaluate the epidemiology and impact of infections caused by Talaromyces marneffei, Coccidioides species, and Paracoccidioides species. PubMed and Web of Sciences databases were searched to identify studies published between 1 January 2011 and 23 February 2021 reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 25, 17, and 6 articles were included for T. marneffei, Coccidioides spp. and Paracoccidioides spp., respectively. Mortality rates were high in those with invasive talaromycosis and paracoccidioidomycosis (up to 21% and 22.7%, respectively). Hospitalization was frequent in those with coccidioidomycosis (up to 84%), and while the duration was short (mean/median 3-7 days), readmission was common (38%). Reduced susceptibility to fluconazole and echinocandins was observed for T. marneffei and Coccidioides spp., whereas >88% of T. marneffei isolates had minimum inhibitory concentration values ≤0.015 μg/ml for itraconazole, posaconazole, and voriconazole. Risk factors for mortality in those with talaromycosis included low CD4 counts (odds ratio 2.90 when CD4 count <200 cells/μl compared with 24.26 when CD4 count <50 cells/μl). Outbreaks of coccidioidomycosis and paracoccidioidomycosis were associated with construction work (relative risk 4.4-210.6 and 5.7-times increase, respectively). In the United States of America, cases of coccidioidomycosis increased between 2014 and 2017 (from 8232 to 14 364/year). National and global surveillance as well as more detailed studies to better define sequelae, risk factors, outcomes, global distribution, and trends are required.

Candida albicans is a common fungal pathogen and amongst the leading causes of invasive candidiasis globally. This systematic review examines the characteristics and global impact of invasive infections caused by C. albicans. We searched on PubMed and Web of Science for studies reporting on criteria such as mortality, morbidity, drug resistance, preventability, yearly incidence, and distribution/emergence during the period from 2016 to 2021. Our findings indicate that C. albicans is the most common Candida species causing invasive disease and that standard infection control measures are the primary means of prevention. However, we found high rates of mortality associated with infections caused by C. albicans. Furthermore, there is a lack of data on complications and sequelae. Resistance to commonly used antifungals remains rare. Although, whilst generally susceptible to azoles, we found some evidence of increasing resistance, particularly in middle-income settings-notably, data from low-income settings were limited. Candida albicans remains susceptible to echinocandins, amphotericin B, and flucytosine. We observed evidence of a decreasing proportion of infections caused by C. albicans relative to other Candida species, although detailed epidemiological studies are needed to confirm this trend. More robust data on attributable mortality, complications, and sequelae are needed to understand the full extent of the impact of invasive C. albicans infections.
