GABA-containing compound gammapyrone protects against brain impairments in Alzheimer's disease model male rats and prevents mitochondrial dysfunction…

2018

Neuroinflammation, oxidative stress, decreased glucose/energy metabolism, and disrupted neurotransmission are changes that occur early in sporadic Alzheimer's disease (AD), manifesting as mild cognitive impairment. Recently, the imbalanced function of the gamma-aminobutyric acid (GABA) system was identified as a critical factor in AD progression. Thus, maintaining balance among neurotransmitter systems, particularly the GABA system, can be considered a beneficial strategy to slow AD progression. The present study investigated the effects of the compound gammapyrone, a molecule containing three GABA moieties: "free" moiety attached to the position 4 of the 1,4-dihydropyridine (DHP) ring, and…

Overactivation of the endocannabinoid system alters the antilipolytic action of insulin in mouse adipose tissue.

2017

Evidence has accumulated that obesity-related metabolic dysregulation is associated with overactivation of the endocannabinoid system (ECS), which involves cannabinoid receptor 1 (CB1R), in peripheral tissues, including adipose tissue (AT). The functional consequences of CB1R activation on AT metabolism remain unclear. Since excess fat mobilization is considered an important primary event contributing to the onset of insulin resistance, we combined in vivo and in vitro experiments to investigate whether activation of ECS could alter the lipolytic rate. For this purpose, the appearance of plasma glycerol was measured in wild-type and CB1R−/− mice after acute anandamide administration or inh…

Delirium Predisposing and Triggering Factors in Nursing Home Residents: A Cohort Trial-Nested Case-Control Study.

2019

Background Delirium is a common geriatric syndrome, with a prevalence of between 15-70% among older long-term care residents. It is associated with adverse outcomes, and its onset may prove imperceptible to health professionals. Few studies in institutionalized older people have analyzed the predictors of delirium. Objective The aim of the present study was to identify delirium predisposing and triggering factors, and develop a predictive model. Methods A cohort trial-nested case-control study covering a period of 12 consecutive months (April 2015 - March 2016) was carried out. Predisposing and triggering episodes of delirium were recorded. Results A total of 443 older persons were recruite…

Invasive Species as Hosts of Zoonotic Infections: The Case of American Mink (Neovison vison) and Leishmania infantum

2021

Leishmania infantum produces an endemic disease in the Mediterranean Basin that affects humans and domestic and wild mammals, which can act as reservoir or minor host. In this study, we analyzed the presence of the parasite in wild American minks, an invasive species in Spain. We screened for L. infantum DNA by PCR using five primer pairs: Two targeting kinetoplast DNA (kDNA), and the rest targeting the ITS1 region, the small subunit of ribosomal RNA (SSU) and a repetitive sequence (Repeat region). The detection limit was determined for each method using a strain of L. infantum and a bone marrow sample from an infected dog. PCR approaches employing the Repeat region and kDNA (RV1/RV2 primer…

Epidemiology, clinical characteristics, resistance, and treatment of infections by Candida auris

2018

Abstract Candida spp. infections are a major cause of morbidity and mortality in critically ill patients. Candida auris is an emerging multi-drug-resistant fungus that is rapidly spreading worldwide. Since the first reports in 2009, many isolates across five continents have been identified as agents of hospital-associated infections. Independent and simultaneous outbreaks of C. auris are becoming a major concern for healthcare and scientific community. Moreover, laboratory misidentification and multi-drug-resistant profiles, rarely observed for other non-albicans Candida species, result in difficult eradication and frequent therapeutic failures of C. auris infections. The aim of this review…

Is it time to combine untargeted antifungal strategies to reach the goal of 'early' effective treatment?

2016

A recently published retrospective study by Posteraro et al. [1] investigated the use of (1–3)-β-D-glucan (BDG) as a strategy for antifungal drug administration in patients at high risk of candidemia. The strategy consisted of the administration of antifungals (anidulafungin in most cases) to septic patients with a Candida score ≥ 3a nd a positive BDG result (≥80 pg/ml). This untargeted strategy led to better selection of patients, avoiding exposure to antifungals in approximately 73 % of patients with negative BDG results and leading to shortened treatment duration in another 20 % of patients. Untargeted antifungal treatments (including prophylaxis, pre-emptive and empiric approaches) are …

What Healthcare Workers Should Know about Environmental Bacterial Contamination in the Intensive Care Unit

2017

Intensive care unit- (ICU-) acquired infections are a major health problem worldwide. Inanimate surfaces and equipment contamination may play a role in cross-transmission of pathogens and subsequent patient colonization or infection. Bacteria contaminate inanimate surfaces and equipment of the patient zone and healthcare area, generating a reservoir of potential pathogens, including multidrug resistant species. Traditional terminal cleaning methods have limitations. Indeed patients who receive a bed from prior patient carrying bacteria are exposed to an increased risk (odds ratio 2.13, 95% confidence intervals 1.62–2.81) of being colonized and potentially infected by the same bacterial spec…
