Mucormycosis is a rare, though increasingly prevalent, life-threatening fungal disease caused by Mucorales. The incidence has increased over the last decade and its mortality remains high at around 50%. Mucormycosis occurs mostly in patients with diabetes mellitus and/or in the context of immunosuppression resulting from chemotherapy for hematological malignancy, hematopoietic stem cell transplantation, or solid-organ transplantation. In this situation, lung and rhino-orbito-cerebral infections are the most frequent localizations of the disease. Prompt initiation of an effective treatment is essential to decrease mortality. However, mucormycosis and aspergillosis share close clinical and radiological features. Invasive procedures such as bronchial endoscopy and/or lung biopsy are necessary to confirm diagnosis, as no indirect tests are yet validated. Therefore, the challenge is to minimize the delay in diagnosis. When present, the reversed halo sign on CT scan is suggestive of mucormycosis. Quantitative polymerase chain reaction is a new promising approach to detect Mucorales DNA in serum and new molecular tools are available to detect Mucorales in tissues as well as to specify species. Recommendations from ECIL and ECMM/ESCMID have recently been published on management of mucormycosis. The recommended treatment is an amphotericin B lipid formulation in combination with surgery and modification of risk factors. MEK pathway High-dose (10 mg/kg) of liposomal amphotericin B is recommended in case of neurological involvement and posaconazole for maintenance therapy. Place of isavuconazole as well as posaconazole new formulations (tablets and intravenous) in first line treatment have to be defined. Improved radiologic descriptions of mucormycosis and new molecular tools may be key elements to help with rapid diagnosis in the future. Clinical trials are warranted to improve therapeutic success and hopefully survival.Inhalation of Cryptococcus into the respiratory system is the main route of acquisition of human infection, yet pulmonary cryptococcosis goes mostly unrecognized by many clinicians. This delay in diagnosis, or misdiagnosis, of lung infections is due in part to frequently subtle clinical manifestations such as a subacute or chronic cough, a broad differential of diagnostic possibilities for associated pulmonary masses (cryptococcomas) and, on occasion, negative respiratory tract cultures. Hematogenous dissemination from the lung can result in protean manifestations, the most severe of which is meningoencephalitis. There are few clinical studies of pulmonary cryptococcosis and its pathogenesis is poorly understood. The main purpose of this review is to describe the epidemiology, clinical presentation, diagnosis, and treatment of pulmonary cryptococcosis to increase clinician's awareness of this diagnostic possibility and to enhance clinical management. Useful pointers to the approach and management of pulmonary cryptococcosis and the implications of disseminated disease are included, together with recommendations for future research.Resistance to the azole antifungals itraconazole, voriconazole, and posaconazole in Aspergillus species is a growing concern. This is especially alarming for A. fumigatus, where acquired resistance has been documented in patients with invasive disease caused by this species that were exposed to these agents, as well as in azole-naive individuals. The primary mechanisms of resistance that have been described in clinical strains include different point mutations in the CYP51A gene, which encodes the enzyme responsible for converting lanosterol to ergosterol via demethylation. Some resistant isolates also contain a tandem repeat in the promoter region of this gene that causes increased expression. These mutations, including TR34/L98H and TR46/Y121F/T289A have also been found in the environment in several areas of the world and have been demonstrated to cause resistance to azole fungicides used in agriculture, thus raising the concern of environmental spread of resistance. Treatment options are limited in patients with infections caused by azole-resistant isolates and include amphotericin B formulations or combination therapy involving an echinocandin. However, there are few clinical data available to help guide therapy, and infections caused by resistant A. fumigatus isolates have been reported to have high mortality rates.Invasive aspergillosis remains an often fatal, difficult-to treat infection in immunocompromised patients. Patients not classically defined as immunocompromised, especially those in an intensive care unit setting, also develop invasive aspergillosis. Clinical clues suggesting angioinvasion and radiographic modalities, especially computed tomographic scans, combined with newer non-culture-based diagnostic techniques, have allowed earlier recognition of invasive aspergillosis. Although mortality remains high, it has greatly decreased over the past 15 years. Voriconazole has supplanted amphotericin B, with its various toxicities, as primary treatment for invasive aspergillosis. Combination therapy with voriconazole and an echinocandin for initial therapy, based on results from a recent controlled clinical trial, could become the standard of care in high-risk patients.An established diagnosis of invasive aspergillus is seldom achieved premortem. Conventional laboratory diagnostic methods such as culture and microscopy, although very useful when positive, are insensitive and time-consuming, resulting in late diagnosis and treatment and contributing to high mortality rates. As a result, routine antifungal prophylaxis and early empirical treatment have been recommended. The use of sensitive and rapid non-culture-based diagnostic assays for the detection of Aspergillus antigens (using commercially available tests to detect galactomannan and 1, 3 β-D-glucan) or detection of genomic DNA sequences may allow a shift in emphasis from empirical to preemptive therapy, especially when substantiated by suggestive radiological findings. These new tools may be used to confirm a presumed diagnosis of invasive aspergillosis, or, when used to screen high-risk patients, may identify an infection at an early stage of disease. Their excellent negative predictive value should convince clinicians to withhold antifungal therapy in patients with no other signs of fungal disease. On the other hand, consecutive positive results should at least trigger a complete diagnostic workup. This article will review the diagnostic utility as well as the pitfalls of using these non-culture-based tools for diagnosing invasive aspergillosis.Bloodstream infection with Candida species is not uncommon in the intensive care unit setting and has the potential to distribute organisms to many different organ systems causing secondary infections, such as endophthalmitis, osteomyelitis, and endocarditis. In some patients, these types of infections become manifested shortly after the episode of candidemia. In others, especially vertebral osteomyelitis, weeks pass before the diagnosis is entertained. Endophthalmitis should be sought by a retinal examination in all patients early after an episode of candidemia. Both osteomyelitis and endocarditis are less common complications of candidemia than endophthalmitis. In patients who manifest symptoms or signs suggesting these infections, magnetic resonance imaging and transesophageal echocardiography, respectively, are extremely helpful diagnostic tests. Newer approaches to the treatment of these infections allow the use of better tolerated, safer antifungal agents. Endophthalmitis is often treated with fluconazole or voriconazole, and the echinocandins are increasingly used, instead of amphotericin B, as initial therapy for osteomyelitis and endocarditis before step-down therapy to oral azole agents.Real-time measurements of many low-abundance volatile organic compounds (VOCs) in breath and air samples are already feasible due to progress in analytical technologies, such as proton transfer reaction mass spectrometry (PTR-MS). Nevertheless, the information content of real-time measurements is not fully exploited, due to the lack of suitable data handling methods. This study develops a data scientific procedure to enhance data analysis and interpretation of longitudinal, multivariate data sets from real-time, in vivo, aroma-release studies. The developed procedure includes an automated data preprocessing and a multivariate assessment of the test panel performance. A large multifactorial PTR-MS data set is investigated that includes four experimental protocols, two tested food products, four aroma compounds, and eight panelists. Real-time measurements are converted into standardized breath profiles by preprocessing, and 10 kinetic parameters are derived. Next to this, panel performance is evaluated per experimental protocol and food product. Comprehensive information about panel performance, individual panelists, studied products, aroma compounds, and kinetic parameters is extracted, demonstrating the great value of the developed approach.In response to seasonality and spatial segregation of resources, sea turtles undertake long journeys between their nesting sites and foraging grounds. While satellite tracking has made it possible to outline their migration routes, we still have little knowledge of how they select their foraging grounds and adapt their migration to dynamic environmental conditions. Here, we analyzed the trajectories and diving behavior of 19 adult green turtles (Chelonia mydas) during their post-nesting migration from French Guiana and Suriname to their foraging grounds off the coast of Brazil. First Passage Time analysis was used to identify foraging areas located off Ceará state of Brazil, where the associated habitat corresponds to favorable conditions for seagrass growth, i.e. clear and shallow waters. The dispersal and diving patterns of the turtles revealed several behavioral adaptations to the strong hydrodynamic processes induced by both the North Brazil current and the Amazon River plume. All green turtles migrated south-eastward after the nesting season, confirming that they coped with the strong counter North Brazil current by using a tight corridor close to the shore. The time spent within the Amazon plume also altered the location of their feeding habitats as the longer individuals stayed within the plume, the sooner they initiated foraging. The green turtles performed deeper and shorter dives while crossing the mouth of the Amazon, a strategy which would help turtles avoid the most turbulent upper surface layers of the plume. These adjustments reveal the remarkable plasticity of this green turtle population when reducing energy costs induced by migration.
In this study we aimed to assess the long-term efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) on depressive symptoms and cognitive performance in patients with drug-resistant major depressive disorder (MDD).

Fifteen drug-resistant depressed outpatients completed an acute trial with augmentative high-frequency rTMS over the left dorsolateral prefrontal cortex (DLPFC) and were compared with 15 drug-resistant MDD patients who underwent sham procedure. Depressive symptoms were evaluated with the Hamilton Depression Rating Scale and Montgomery-Asberg Depression Rating Scale. The Frontal Assessment Battery and the Stroop Color-Word Test Interference (Stroop T) were used to probe executive functions. Outcome measures were obtained at baseline, 4 weeks after the rTMS, as well as 3 months and 6 months after the end of the stimulation protocol.

After the active rTMS, patients showed a significant decrease in the scores at the depression rating scales that lasted for 6 months. A transient improvement was also observed at the Stroop T, although it did not persist in time.
