Conclusion These data suggest that a universal PrEP program targeting 5-year-olds would be cost-effective in the Philippines.Objectives To study the prevalence of fungal species in CF patients over a 16 years period, as well as the impact of C. albicans, C. dubliniensis and A. fumigatus on lung function. Methods Observational single-center cohort study (2000-2015) including 133 CF patients (ages 6-66 years). TTI 101 Linear mixed models with autoregressive covariance matrix were used. Results C. albicans was the most common fungus (prevalence 62%) followed by A. fumigatus (22%) and C. dubliniensis (11%). In the initial year of detection, there was no impact of C. albicans, C. dubliniensis or A. link2 fumigatus on lung function. However, one and two years after detection of C. dubliniensis a reduction in ppFEV1 with 3.8%, p=0.022, (year 1) and with 4.1%, p=0.017 (year 2) compared to CF patients without these findings, was observed. Furthermore, patients with positive cultures for any of these fungal species for three consecutive years exhibited a decline in lung function (C. dubliniensis, 7.6% reduction in ppFEV1, p=0.001; A. fumigatus, 4.9%, p=0.007; C. albicans, 2.6%, p=0.014). The results were adjusted for age, CFTR genotype, chronic and intermittent P. aeruginosa colonization and numbers of intravenous antibiotic treatments per year. Persistence of C. dubliniensis for three consecutive years was correlated positively to age and ESR (both p=0.001). Conclusions CF patients who were cultured positive for C. dubliniensis, C. albicans or A. fumigatus in sputum exhibited a decline in ppFEV1 over time. The effect was most pronounced for C. dubliniensis.Background Data about the impact of left atrial appendage thrombosis (LAAT) on early safety and mortality in patients undergoing transfemoral transcatheter aortic valve implantation (TF-TAVI) are scarce. We aimed to investigate the incidence and predictors of LAAT and the outcome associated with this condition in patients treated by TF-TAVI. Methods Retrospective data analysis derived from a prospective single-center registry comparing patients with and without LAAT regarding early safety at 30-days according to Valve Academic Research Consortium-2 (VARC-2) and 2-year mortality. Results LAAT was found in 7.6% of the whole cohort (n=2527) and in 16.6% in those patients with known pre-existing atrial fibrillation (AF cohort, n=1099). Compared to controls, patients with LAAT were sicker indicated by a higher STS-Score and burden of comorbidities. Neither VARC-2 defined early safety at 30-days nor the rate of stroke was different between LAAT and controls in both the whole (early safety 29.2% vs. 24.2%, p=.123; stroke 5.9% vs. 4.7%, p=.495) and AF cohort (early safety 29.1% vs. 22.9%, p=.072; stroke 5.6% vs. 3.3%, p=.142). Evaluating the whole cohort in a univariate analysis, the 2-year mortality was significantly higher in LAAT compared to controls (HR 1.41 [95% CI 1.07-1.86], p=.014). However, multivariate analysis of the whole cohort and the AF cohort revealed no association between LAAT and 2-year mortality. Conclusion LAAT was frequent in patients undergoing TF-TAVI, in particular in patients with a history of AF, but it was not associated with an increase in periprocedural complications and did not predict 2-year mortality.Despite a well-established risk of chronic kidney disease (CKD) after allogeneic hematopoietic cell transplant (allo-HCT), the benefits of using nephrotoxic anti-infective agents to treat serious peritransplant infections often outweigh this risk. While there is no consensus on the optimal management of post-allo-HCT human herpes virus 6 (HHV6) reactivation, the nephrotoxic drug foscarnet is often used, although its long-term impact on renal function has not been established. link3 We retrospectively reviewed 987 adult patients who underwent transplantation between 2002 and 2016, of whom 45.3% (n = 447) were exposed to foscarnet. The most frequent indications for foscarnet treatment were cytomegalovirus (n = 257, 57.5%) and HHV6 (n = 139, 31.1%). In the first 3 months post-transplant, patients exposed versus unexposed had similar rates of acute kidney injury and acute kidney failure (defined as 3 times baseline creatinine or 30% decrease in eGFR from baseline to 12 months compared to those who were not (odds ratio, 2.30; 95% CI, 1.40 to 3.78; P = .001). We conclude that foscarnet use following allo-HCT had a profound impact on long-term renal function independent of other transplant-related factors.The central renin angiotensin system (RAS) is implicated in Alzheimer's disease (AD). Here, induction of experimental AD simulation was performed by D-galactose (D-Gal) injection to ovariectomized (OVX) rats fed on high fat high fructose diet (HFFD). Telmisartan administration to OVX/HFFD/D-Gal rats lowered the expression of hippocampal angiotensin 1 and 2 receptors and glucose transporter 2 in addition to lowering of the peripheral and central glucose levels. Furthermore, it improved cognitive impairment and suppressed hippocampal amyloidogenic markers including amyloid-beta level, phosphorylated tau protein and beta site amyloid precursor protein cleaving enzyme 1 expression, while elevated levels of insulin degrading enzyme and recovered permeability of blood brain barrier (BBB). In addition, it inhibited hippocampal oxido-nitrosative stress as well as neuroinflammatory and apoptotic biomarkers. Telmisartan improved memory and cognitive impairment as shown in the behavioral Morris water maze, Y-maze, novel object recognition and open field tests in addition to amelioration of depressive like behavior as shown in forced swimming test. Histopathological examination of brain and immune expression of glial fibrillary acidic protein were also improved together with astrogliosis improvement. In conclusion, telmisartan improved memory and cognitive impairment, recovered amyloidogenesis-hyperglycemic axis, astrogliosis, integrity of BBB, memory deficit and oxidonitrosative stress induced in OVX/HFFD/D-Gal rats.Bisphenol-A (BPA) is one of the extensively studied estrogenic endocrine disrupting chemicals (EDC) with ubiquitous exposure among humans and wildlife. While there are literature reporting the association of dysregulated Brain-derived neurotrophic factor (BDNF) expression levels with altered cognitive and emotional behaviour such as anxiety-like and stress behaviour in animal models, there are no studies in BPA that investigate these altered neurobehavioural outcomes in parallel with the expression of intracellular proteins involved in BDNF signaling pathway. In this study, pregnant Wistar rats were exposed to BPA through water (25 μg/L, 250 μg/L, and 2.5 mg/L) during gestation day (GD) 9-21. Prenatal BPA exposure, increased anxiety-like behaviour in males and decreased exploratory behaviour in both male and female offspring. Downregulation of both BDNF and CYP19A1 genes were observed in male BPA-exposed offspring, whereas in females, the expression was upregulated. The expression of p-AKT, p-MEK and p-ERK proteins were increased in males, while in females, it decreased. Both the male and the female BPA-exposed offspring exhibited elevated levels of DNMT1 protein. The sex-specific alteration in the expression of CYP19A1 and DNA methyltransferase 1 (DNMT1) suggests that both hormonal and epigenetic dysregulation could underlie the long-term BPA-induced effect on anxiety-like behaviour in the offspring.The aim of this study was to evaluate the effects of different solvents and maximize the extraction of bioactive compounds from jabuticaba (Myrciaria cauliflora) seeds. In general, the solvent system composed of water and propanone (5248 v/v) modified the extract polarity and increased extraction yield of bioactive compounds. The optimized extract presented antioxidant capacity measured by different chemical and biological assays. The optimized extract exerted antiproliferative and cytotoxic effects against A549 and HCT8 cells, antimicrobial and antihemolytic effects, inhibited α-amylase/α-glucosidase activities and presented in vitro antihypertensive effect. Nonetheless, the optimized extract showed no cytotoxicity in a human cell model (IMR90). Vescalagin, castalagin and ellagic acid were the major phenolic compounds in the optimized extract. Our results show that jabuticaba seed may be a potential ingredient for the development of potentially functional foods.FOXOs belong to the forkhead transcription factor superfamily, several of which are suggested to be involved in the control of food intake. Previously, we proved that the neuropeptide FF (NPFF) peptide was involved in feeding regulation in spotted sea bass. In the present study, seven members of the foxo family were identified in the whole genome of spotted sea bass. The distributions of these genes in different tissues were analyzed by qRT-PCR. Variations in the foxo1a and npff expression profiles during short-term starvation showed similar expression patterns. The colocalization of foxo1a and npff in the telencephalon, hypothalamus, stomach and intestine further provided evidence that foxo1a may act directly to promote the transcription of npff. Thirteen predicted FOXO1 binding sites were found in the 5' upstream region of npff. Luciferase assay results showed that FOXO1A was able to activate npff transcriptional responses by directly binding DNA response elements, and the key regulatory areas and sites of FOXO1A on the npff promoter were confirmed by deletion and site-directed mutagenesis analyses. These findings may help to elucidate the role of FOXO1 in the regulation of feeding processes in teleosts.Concern over global amphibian declines and possible links to agrochemical use has led to research on the endocrine disrupting actions of agrochemicals, such as fertilizers, fungicides, insecticides, acaricides, herbicides, metals, and mixtures. Amphibians, like other species, have to partition resources for body maintenance, growth, and reproduction. Recent studies suggest that metabolic impairments induced by endocrine disrupting chemicals, and more particularly agrichemicals, may disrupt physiological constraints associated with these limited resources and could cause deleterious effects on growth and reproduction. Metabolic disruption has hardly been considered for amphibian species following agrichemical exposure. As for metamorphosis, the key thyroid hormone-dependent developmental phase for amphibians, it can either be advanced or delayed by agrichemicals with consequences for juvenile and adult health and survival. While numerous agrichemicals affect anuran sexual development, including sex reversal anssment of agrochemicals that alter cross-talk between hormonal systems must be further addressed. Given the diversity of life-history traits in Anura, Caudata, and the Gymnophiona, it is essential that studies on endocrine disruption expand to include the lesser known taxa. Research under ecologically-relevant conditions will also be paramount. Closer collaboration between molecular and cellular endocrinologists and ecotoxicologists and ecologists is thus recommended.Laccase from Botryosphaeria rhodina MAMB-05 was covalently immobilized on carboxymethyl-botryosphaeran by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide and N-hydroxysuccinimide (EDC/NHS) in aqueous solution. This approach was employed to fabricate a novel laccase-based biosensor to electrochemically quantify quercetin (QCT), using a simple carbon black paste electrode as a transducer. The proposed biosensor was characterized by electrochemical impedance spectroscopy and Nyquist plots were used to evaluate the immobilization of the enzyme. For determining QCT, variables were optimized, that included experimental conditions for laccase immobilization, pH of the supporting electrolyte, and instrumental parameters of the electroanalytical technique. From square-wave-voltammograms, a linear dependence between the cathodic current peak and QCT concentration was observed within the range 4.98-50.0 × 10-8 mol L-1, with a theoretical detection limit of 2.6 × 10-8 mol L-1. The proposed method was successfully applied to determine QCT in beverages, pharmaceuticals, and biological samples.
