Advances in the knowledge and therapeutics of schizophrenia, major depression disorder, and bipolar disorder from human brain organoid research.

Tridimensional cultures of human induced pluripotent cells (iPSCs) experimentally directed to neural differentiation, termed "brain organoids" are now employed as an assay that recapitulates early developmental stages of nervous tissue differentiation. Technical progress in culture methodology enabled the generation of regionally specialized organoids with structural and neurochemical characters of distinct encephalic regions. The technical process of organoid elaboration is undergoing progressively implementation, but current robustness of the assay has attracted the attention of psychiatric research to substitute/complement animal experimentation for analyzing the pathophysiology of psychiatric disorders.

Heterogeneity in the association between prediabetes categories and reduction on glomerular filtration rate in a 5-year follow-up.

Sports facilities, socio-economic context and overweight among the childhood population in two southern European cities: a cross sectional study.

Background: To evaluate relationship between socio-economic environment and overweight in Madrid and Barcelona, adjusting for possible confounding factors.

Methods: We obtained three indicators which reflected socio-economic context, namely, unemployment rate, percentage of population with tertiary education, and percentage with a second home. The design is a cross sectional study.

Variation in mortality inequalities in the autonomous communities of Spain: a matter of mortality in people with less education.

Background: Given the importance of mortality rates in each socioeconomic group, as explanation for the variation in mortality inequalities across populations, the objective of the present study is to evaluate whether regional variation in mortality inequalities in Spain is related to the mortality rates in different socioeconomic groups.

Methods: The study included all persons aged 30-74 years living in Spain in 2001 and followed up for mortality over 7 years. In each of the 17 autonomous communities of Spain mortality rates were estimated for those with low and high education, as well as two measures of mortality inequality according to education: mortality rate difference and mortality rate ratio.

Socio-economic environment, area facilities and obesity and physical inactivity among children.

Background: To evaluate whether the relationship between socio-economic environment and obesity and physical inactivity in children can be explained by household socio-economic position and area facilities.

Methods: Two indicators of the socio-economic context of neighbourhood of residence based on wealth and deprivation were estimated in a sample of 727 children and adolescents residents in Madrid (Spain). Multilevel logit models were used to calculate the relationship between each indicator and obesity and physical inactivity.

Socioeconomic position and childhood-adolescent weight status in rich countries: a systematic review, 1990-2013.

Background: Childhood obesity is a major problem in rich countries due to its high prevalence and its harmful health consequences. An exploratory analysis conducted in the PubMed database highlighted that the number of papers published on the relationship between socioeconomic position (SEP) and childhood-adolescent weight status had risen substantially with respect to an earlier review which had covered the period 1990-2005.

Methods: To describe the findings on the relationship between SEP and childhood-adolescent weight status in papers published in rich countries from 1990 through 2013, studies were identified in the following databases: PubMed; Web of Knowledge (WOK); PsycINFO; Global Health; and Embase.

Risk behaviors and sports facilities do not explain socioeconomic differences in childhood obesity: a cross-sectional study.

Background: To assess whether the relationship between neighborhood socioeconomic context of residence and childhood obesity is explained by family socioeconomic position, risk behaviors and availability of sports facilities.

Methods: Based on the income and educational level of residents in the neighborhoods of the city of Madrid, two indicators of socioeconomic context were calculated using the information about income and education and grouped into quartiles. In a sample of 727 children aged 6-15 years, the relationship of these indicators with overweight and obesity was studied using multilevel logit models.

Mindfulness-based cognitive therapy versus psychoeducational intervention in bipolar outpatients with sub-threshold depressive symptoms: a randomized controlled trial.

Background: The presence of depressive subsyndromal symptoms (SS) in bipolar disorder (BD) increases the risk of affective relapse and worsens social, cognitive functioning, and quality of life. Nonetheless, there are limited data on how to optimize the treatment of subthreshold depressive symptoms in BD. Mindfulness-Based Cognitive Therapy (MBCT) is a psychotherapeutic intervention that has been shown effective in unipolar depression.

Neurobiology of major depressive disorder.

We survey studies which relate abnormal neurogenesis to major depressive disorder. Clinically, descriptive gene and protein expression analysis and genetic and functional studies revised here show that individual alterations of a complex signaling network, which includes the hypothalamic-pituitary-adrenal axis; the production of neurotrophins and growth factors; the expression of miRNAs; the production of proinflammatory cytokines; and, even, the abnormal delivery of gastrointestinal signaling peptides, are able to induce major mood alterations. Furthermore, all of these factors modulate neurogenesis in brain regions involved in MDD, and are functionally interconnected in such a fashion that initial alteration in one of them results in abnormalities in the others.

Area-based socioeconomic environment, obesity risk behaviours, area facilities and childhood overweight and obesity: socioeconomic environment and childhood overweight.

Objective: The objective of this study is to evaluate whether the relation between area-based socioeconomic environment and childhood obesity can be explained by household socioeconomic position, obesity-related risk behaviours and area facilities.

Methods: Two indicators of socioeconomic environment based on wealth and deprivation were estimated in a sample of 4529 Spanish children and adolescents in 2006. Multilevel logit models were used to calculate the relation between each indicator and obesity.

The cerebellum and neuropsychiatric disorders.

Relative to non-human primates, in humans the cerebellum, and prefrontal cortex are brain regions which have undergone major evolutionary changes. In recent decades, progress in molecular biology and advances in the development of functional neuroimaging analysis have shown that the evolution of the human cerebellum was accompanied by the acquisition of more functions than were previously deduced from human post-mortem studies and animal experimentation. These new cerebellar functions included the control of attention and other cognitive functions, emotions and mood, and social behavior, which were all thought to represent cortical functions.

Emergence in Spain of a multidrug-resistant Enterobacter cloacae clinical isolate producing SFO-1 extended-spectrum beta-lactamase.

Between February 2006 and October 2009, 38 patients in different wards at the A Coruña University Hospital (northwest Spain) were either infected with or colonized by an epidemic, multidrug-resistant (MDR), and extended-spectrum-β-lactamase (ESBL)-producing strain of Enterobacter cloacae (EbSF), which was susceptible only to carbapenems. Semiautomated repetitive extragenic palindromic sequence-based PCR (rep-PCR) and pulsed-field gel electrophoresis (PFGE) analysis revealed that all of the E. cloacae isolates belonged to the same clone.

Development of an alarm management system to manage those alarms occurred during the illness prevention and management inside and outside the hospital environment.

A great amount of information is available to be exploited thanks to the use of information technologies. However, the systems that analyze this data lack the ability to alert the right clinical staff to important events, having some of the latest developments centered on the possibility of sending events from specific areas. The following system tries to solve these dependencies and offers a unique system capable of analyzing any data source and communicates the alarms through different means in an effective way.

Rapid and simple determination of ciprofloxacin resistance in clinical strains of Escherichia coli.

We recently reported a simple new in situ diffusion assay, developed as a kit, to visualize DNA fragmentation in single bacterial cells. Use of this assay in a collection of 95 genetically unrelated Escherichia coli clinical strains resulted in correct identification of all of the isolates as resistant or susceptible to ciprofloxacin, consistent with the MIC results. This relevant information is obtained in 80 min.

Plantago ovata consumption and colorectal mortality in Spain, 1995-2000.

Background: Consumption of Plantago ovata may protect against colorectal cancer. To test this hypothesis, an ecological study was performed to determine mortality rates and distribution of colorectal cancer, and the consumption and distribution of P ovata, in different provinces in Spain. The putative association between P ovata consumption and mortality from colorectal cancer was then evaluated.

[Glycopeptide-resistant Enterococcus faecium in a hospital in northern Spain. Molecular characterization and clinical epidemiology].

Introduction: Glycopeptide resistance in Enterococcus spp. is a clinical problem because of the rapid dissemination of these microorganisms, possible transfer of vancomycin resistance to more virulent pathogens, such as Staphylococcus aureus, and the limited therapeutic possibilities for the infections they cause. In this study, 10 strains of vancomycin-resistant Enterococcus faecium isolated from 10 different patients in our hospital during 2004 to 2005 were characterized.

Comparison of different methods of determining beta-lactam susceptibility in clinical strains of Pseudomonas aeruginosa.

One hundred and one randomly selected (2003-2005) clinical isolates of Pseudomonas aeruginosa were used to assess the quantitative (MIC) and qualitative (susceptibility category) agreement between the microdilution broth reference method (RM) and disc diffusion (DD), Etest and the VITEK 2 automated susceptibility test system for determination of the susceptibility of P. aeruginosa to piperacillin (PIP), PIP-tazobactam (TZP), ceftazidime (CAZ), aztreonam (ATM) cefepime (FEP) and imipenem (IMP). The results obtained by the RM were compared with those obtained by the other methods.

Nosocomial Outbreaks Caused by Leuconostoc mesenteroides subsp. mesenteroides.

From July 2003 through October 2004, 42 patients became infected by strains of Leuconostoc mesenteroides subsp. mesenteroides (genotype 1) in different departments of Juan Canalejo Hospital in northwest Spain. During 2006, 6 inpatients, also in different departments of the hospital, became infected (genotypes 2-4).

Structure-function studies of arginine at position 276 in CTX-M beta-lactamases.

Objectives: In order to assess whether or not the Arg-276 of CTX-M-type enzymes is equivalent to the Arg-244 of IRT-TEM-derivative enzymes, we replaced the former with six different amino acids, some of them previously described as involved in resistance to beta-lactamase inhibitors in TEM-IRT derivatives. We also investigated the role of Arg276 in cefotaxime hydrolysis.

Methods: By site-directed mutagenesis and by use of the bla(CTX-M-1) gene as template, Arg-276 was replaced with six different amino acids (Trp, His, Cys, Asn, Gly and Ser).

Cloning, nucleotide sequencing, and analysis of the AcrAB-TolC efflux pump of Enterobacter cloacae and determination of its involvement in antibiotic resistance in a clinical isolate.

Enterobacter cloacae is an emerging clinical pathogen that may be responsible for nosocomial infections. Management of these infections is often difficult, owing to the high frequency of strains that are resistant to disinfectants and antimicrobial agents in the clinical setting. Multidrug efflux pumps, especially those belonging to the resistance-nodulation-division family, play a major role as a mechanism of antimicrobial resistance in gram-negative pathogens.

Molecular characterization of the gene encoding a new AmpC beta-lactamase in Acinetobacter baylyi.

Objectives: The main objective of the present study was to demonstrate the presence of a beta-lactamase ampC gene in the chromosome of the non-pathogenic bacterium Acinetobacter baylyi ADP1.

Methods: beta-Lactam MICs were determined by Etest. The ampC gene was amplified by PCR, with specific oligonucleotides, then cloned into pBGS18 and pAT-RA plasmids and transformed into Escherichia coli TG1 and parental A.
