RESUMO

Cefiderocol is a new molecule effective against multidrug-resistant (MDR) Gram-negative pathogens. Currently, there is limited evidence regarding the use of cefiderocol in central nervous system (CNS) infections. Data on the cerebrospinal fluid penetration rate of cefiderocol are limited and heterogeneous, and there is no consensus on the dosing scheme of cefiderocol to penetrate the blood-brain barrier. We present a case series and a literature review of CNS infections caused by MDR pathogens that were treated with cefiderocol: some of these patients were treated with different dose schemes of cefiderocol and underwent therapeutic drug monitoring both on plasma and cerebrospinal fluid (CSF). The CSF penetration rates and the clinical outcomes were evaluated.

RESUMO

Trichosporon spp. endocarditis is a severe and hard-to-treat infection. Immunosuppressed subjects and carriers of prosthetic valves or intracardiac devices are at risk. This article presents the case of an immunocompetent 74-year-old man affected by endocarditis of the prosthetic aortic valve. After Bentall surgery, cultures of the removed valve demonstrated Trichosporon ashaii as the etiological agent. The patient was treated with amphotericin B at first and subsequently with fluconazole. Given the fragility of the patient and the aggressiveness of the pathogen, life-long prophylactic therapy with fluconazole was prescribed. After 5 years follow-up, no drug-related toxicities were reported and the patient never showed any signs of recurrence. The review of the literature illustrates that Trichosporon spp. endocarditis may present even many years after heart surgery, and it is often associated with massive valve vegetations, severe embolic complications, and unfavorable outcome. Due to the absence of international guidelines, there is no unanimous therapeutic approach, but amphotericin B and azoles are usually prescribed. Additionally, a prompt surgical intervention seems to be of paramount importance. When dealing with a life-threatening disease, such as mycotic endocarditis of prosthetic valves, it is essential to consider and treat even rare etiological agents such as Trichosporon spp.

RESUMO

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) affect 60-90% of patients with Alzheimer's disease (AD). OBJECTIVE: To determine if environmental therapy is an effective strategy to reduce BPSD, we tested 163 patients with AD with Neuropsychiatric Inventory (NPI) before and after 6 months of an indoor therapeutic garden (TG) or standard environment. METHODS: A single-blind randomized controlled trial on AD patients with BPSD. Participants were randomized to an indoor TG (N = 82), or standard environment (control, N = 81) for 6 months. PRIMARY OUTCOME: change in the NPI score from baseline (T0) to end of treatment (T1). SECONDARY OUTCOMES: change in use of quetiapine, cognition, activities of daily living, salivary cortisol, blood pressure from T0 to T1. RESULTS: NPI score significantly ameliorated (TG versus control: -31.8 points), quetiapine dosage (-150 mg), blood pressure (-2.6 mm Hg), and salivary cortisol (-6.4 to -2.1 Nmol/l) were significantly reduced, the Mini-Mental State Examination significantly improved (1.8 points) in the TG versus control arm at T1 (p < 0.001). No adverse events were reported. CONCLUSION: The indoor TG seems safe and may reduce BPSD, medication intake, and cortisol levels in AD.

RESUMO

Sundowning syndrome (SDS) in patients with Alzheimer's disease (AD) is characterized by the intensification of behavioral disorders at sunset. Despite SDS etiology being unclear, a strong relationship between high cortisol levels and SDS has been reported. Aerobic exercise (AE) and cognitive training (CT) can reduce cortisol levels. However, whether SDS would benefit from AE and CT is still unknown. Therefore, the aim of this study was to investigate whether AE and CT treatments are effective in reducing SDS via downregulation of cortisol levels. The possible additive effects of combined AE+CT were also assessed. Eighty AD patients were randomly assigned to AE (n = 20), CT (n = 20), AE+CT (n = 20), and standard therapy (no treatment, NT; n = 20). Treatments were administered for 3 months, 5 days/week, 1 hour before sunset. Before and after treatments, salivary cortisol levels were sampled at 7, 11, 15, at sunset, and 20 (time of day). Blind assessment of behavioral disorders (neuropsychiatric inventory, NPI) and agitation (agitated behavior scale, ABS) were also performed. After interventions, cortisol levels were reduced in AE and AE+CT by ∼26%. In the same groups, NPI and ABS decreased by ∼50%. By contrast, cortisol and behavioral disorders were similar to baseline in CT and NT. Changes in NPI and ABS were significantly correlated with the reduction in cortisol levels. AE or AE+CT effects on SDS and cortisol levels and the lack of effect of CT alone indicate the effectiveness of an exercise-based treatment on SDS, suggesting a possible hypothalamic-pituitary-adrenal axis dysregulation underpinning SDS.
