The 2021 revised guidelines of the World Health Organization recommend monitoring the quality of sand in addition to water at recreational beaches. This review provides background information about the types of beaches, the characteristics of sand, and the microbiological parameters that should be measured. Analytical approaches are described for quantifying fungi and fecal indicator bacteria from beach sand.

Background: is a saprophytic fungus, ubiquitous in the environment and responsible for causing infections, some of them severe invasive infections. The high morbidity and mortality, together with the increasing burden of triazole-resistant isolates and the emergence of new risk groups, namely COVID-19 patients, have raised a crescent awareness of the need to better comprehend the dynamics of this fungus. The understanding of the epidemiology of this fungus, especially of CAPA isolates, allows a better understanding of the interactions of the fungus in the environment and the human body.

We evaluated the biofilm formation and antimicrobials resistance (AMR) of complex and co-isolated from a CRBSI patient. Antimicrobial susceptibility of central venous catheters (CVCs) and hemoculture (HC) isolates was evaluated, including whole genome sequencing (WGS) resistome analysis and evaluation of gene expression to obtain insight into their AMR determinants.

IFI are often difficult to diagnose and manage, and can be associated with substantial morbidity and mortality. This study aims to contribute to understanding the etiology of invasive and subcutaneous fungal infections, their associated risk factors, and to perceive the outcome of patients who developed invasive disease, raising awareness of these infections at a local level but also in a global context.

Recently, new risk groups for the development of aspergillosis have emerged-patients with influenza- or COVID-19-ssociated pulmonary aspergillosis. The rise and spread of antifungal resistances have also become a clinical concern in some geographic areas and have drawn the attention of clinicians due to difficulties in treating these infections.

Alveolar damage in the context of acute respiratory distress syndrome (ARDS) appears to be the culprit in facilitating fungal invasion in COVID-19 patients, leading to a COVID-19-associated pulmonary aspergillosis (CAPA) phenomenon. From November 2020 to 15 February 2021, 248 COVID-19 patients were admitted to our ICUs, of whom ten patients (4% incidence) were classified as either probable (six) or possible (four) CAPA cases.

Adolescence is a period of great changes and the assumption of risk behaviours at the level of sexuality may have implications for health and well-being. Nowadays, adolescents live free from constraints and prioritise freedom, using their own terminology to label their relationships, it becoming in turn important to conceptualise intimacy relationships from their perspective. Therefore, a qualitative, descriptive, and exploratory study was performed.

Two retrospective laboratory studies were conducted on surveillance at the Portuguese National Mycology Reference Laboratory. The first, covering the period 2017-2018, aimed to study the molecular epidemiology of 256 isolates obtained from patients with respiratory, subcutaneous, or systemic infections and from environmental samples.

In Portugal, the section is one of the most frequent, and resistant strains to have been found in clinical and environmental contexts. Although several cryptic species within the section show intrinsic resistance to azoles, one factor driving (acquired) resistance is selective pressure deriving from the extensive use of azoles.

View Article and Find Full Text PDFDiagnosis of invasive fungal infections is complex, and the lack of standardization of molecular methods is still a challenge. Several methods are available for the diagnosis of invasive aspergillosis, but their effectiveness will depend on the studied population, the patients' comorbidities, and the use of mold active prophylaxis, among others. The ability to determine the identity of the infecting species, and to detect mutations conferring specific resistance patterns directly from DNA extracted from the biological product, is an advantage of nucleic acid testing compared with antigen-based assays.
