INTRODUCTION: Cognitive change in people at risk of Alzheimer's disease (AD) such as subjective memory complainers is highly variable across individuals. METHODS: We used latent class growth modeling to identify distinct classes of nonlinear trajectories of cognitive change over 2 years follow-up from 265 subjective memory complainers individuals (age 70 years and older) of the INSIGHT-preAD cohort. We determined the effect of cortical amyloid load, hippocampus and basal forebrain volumes, and education on the cognitive trajectory classes...

Patient-ventilator asynchrony may occur with modes of partial ventilatory support. Because this problem is associated with worsened outcomes, identifying and managing asynchronies has been recognized as a relevant clinical problem during both invasive and non-invasive (NIV) mechanical ventilation. Areas covered: In this review article, we first describe the different forms of patient-ventilator asynchrony and how they are classified and quantified. Then, we show how these asynchronies can be recognized, considering the techniques used to properly detect asynchronies, by either ventilator waveform observation, or through systems based on more complexes mathematical algorithms, by means of adjunctive signals, such as the electrical activity of the diaphragm or esophageal pressure...

Several species of the genus Ceiba (Malvaceae) are ethnopharmacologically used. Thus, this study aimed to investigate the in vitro beneficial properties of the aqueous stem bark extract of Ceiba speciosa. The extract presented a great amount of phenolic compounds (117.4 ± 6.2 mg GAE/g). The antioxidant activity was assessed by DPPH (IC50  = 42.87 μg/mL), ORAC (2351.17 μmol TE/g) and FRAP (235.94 μM FeSO4 /g) methods. In addition, the extract reduced MCF-7 cell viability as assessed by MTT. However, it prevented mitochondrial membrane depolarization and reduced caspase-9 activity induced by hydrogen peroxide...

BACKGROUND: Mexico recently enacted drug policy reform to decriminalize possession of small amounts of illicit drugs and mandated that police refer identified substance users to drug treatment. However, the economic implications of drug treatment expansion are uncertain. We estimated the costs of opioid substitution therapy (OST) provision in Tijuana, Mexico, where opioid use and HIV are major public health concerns. METHODS: We adopted an economic health care provider perspective and applied an ingredients-based micro-costing approach to quantify the average monthly cost of OST (methadone maintenance) provision at two providers (one private and one public) in Tijuana, Mexico...

The objective of this study was to investigate the effect and the mechanism of action of fernenediol as insulin secretagogue. Wistar rats were treated with 0.1; 1 and 10 mg/kg fernenediol and then induced hyperglycemia by oral glucose. The glycaemia, insulin, LDH, calcium and hepatic glycogen were analyzed. Considering the intestine and pancreas as targets for the triterpene action, the duodenum was used to verify the influence of fernenediol on intestinal glycosidases. Additionally, pancreatic islets were used for studies of 14 C-deoxyglucose uptake and influx of 45 Ca2+ in hyperglycemic medium with/without fernenediol in the presence/absence of an inhibitor/activator of KATP channels, glibenclamide, diazoxide, nifedipine, calcium chelator (BAPTA- AM) and H-89 and ST the inhibitors of the PKA and PKC enzymes...

Populations at the climatic margins of a species' distribution can be exposed to conditions that cause developmental stress, resulting in developmental abnormalities. Even within the thermal range of normal development, phenotypes often vary with developmental temperature (i.e., thermal phenotypic plasticity). These effects can have significant consequences for organismal fitness and, thus, population persistence. Reptiles, as ectotherms, are particularly vulnerable to thermal effects on development and are, therefore, considered to be at comparatively high risk from changing climates...

Intraventricular gangliogliomas presenting with spontaneous hemorrhage are rare. Due to high density of important tracts lateral to the ventricular atrium, the intraparietal trans sulcal approach is a good option to remove lesions in this location. These tracts are displaced and sometimes destroyed by the presence of large masses. A 33-year-old male presented with a sudden headache and a generalized seizure. He had a left visual field hemianopia and left visual field neglect. Brain computer tomography and magnetic resonance imaging revealed a hemorrhagic tumor located in his right atrium...

miRNAs are small noncoding RNA molecules that have a very important role in gene expression regulation and, therefore, in cell homeostasis. SNPs in certain miRNA-related genes have been shown to influence cancer risk and prognosis. miRNA cellular processing is complex and involves multiple proteins. XPO5 is a key factor in this process as it is responsible for the nuclear export of the precursor pre-miRNA to the cytoplasm, where it will be further processed to its final miRNA conformation in order to be loaded to RNA inducing silencing complex to exert its regulatory effect...

Dilated cardiomyopathy is the most common form of cardiomyopathy and the main cause of cardiac transplantation in children and in adults. Infants and children have a wider spectrum of etiologies, hampering their identification. The most frequent initial manifestation of dilated cardiomyopathy is symptomatic heart failure during exercise or at rest (although many patients are asymptomatic). Some causes are potentially reversible, therefore the investigation should be carefully planned and immediately performed after diagnosis...

Corticoids are actives widely used in the treatment of skin diseases. This work aims to study the penetration of three corticoids (betamethasone, clobetasol and flurandrenolide), their relationship with their Log D values and the effects of the vehicles. The three compounds were applied on a Franz-type diffusion cell in propylene glycol solution and their respective commercial creams and ointments. The active amounts found in the stratum corneum, epidermal and dermal layers of the skin were investigated. Their diffusions were greatly affected by the formulation, moreover higher amounts of substance in the epidermis and dermis were detected in ointments than in creams...

Information on prevalence of special needs in internationally adopted children (IAC) is incomplete. We reviewed data from 422 IAC screened at a single Centre in Italy in 2015-16. Prevalence of special needs reached 17.1% (n = 72). Among these children, the most frequent conditions were fetal alcohol spectrum disorders (FASD; n = 30; 7.1%), cleft lip palate (n = 8; 1.9%) and other congenital malformations (n = 20; 4.7%). Worrisomely, 25 out of 52 (48.1%) Russian children presented with FASD.

Seafood consumption is a major route for human exposure to environmental contaminants of emerging concern (CeCs). However, toxicological information about the presence of CeCs in seafood is still insufficient, especially considering the effect of cooking procedures on contaminant levels. This study is one among a few who evaluated the effect of steaming on the levels of different CeCs (toxic elements, PFCs, PAHs, musk fragrances and UV-filters) in commercially relevant seafood in Europe, and estimate the potential risks associated with its consumption for consumers...

The small tree Allophylus africanus, widespread in the African continent, has long been considered valuable, as noted by the number of reports on their multiple medicinal uses. With this work, we aimed to extend the current, and so far restricted, knowledge on the chemical composition of the plant, particularly as source of flavonoids, as well as to assess its potential anti-inflammatory properties. The chemical characterization of the aqueous extract obtained from the leaves allowed the identification and quantitation of 30 flavones, predominantly apigenin derivatives, but also four luteolin derivatives, while the stem bark extract was solely characterized by apigenin di-C-glycosides and mono-C-glycosides-O-glycosylated...

Life expectancy is increasing worldwide, with a resultant increase in the elderly population. Aging is characterized by the progressive loss of skeletal muscle mass and strength - a phenomenon called sarcopenia. Sarcopenia has a complex multifactorial pathogenesis, which involves not only age-related changes in neuromuscular function, muscle protein turnover, and hormone levels and sensitivity, but also a chronic pro-inflammatory state, oxidative stress, and behavioral factors - in particular, nutritional status and degree of physical activity...
