Disentangling the actual Psycholinguistic Loci involving Anomia with Mental Psychometric Types.
PURPOSE OF REVIEW Multiple lines of evidence support a role of the host genetic component in Mycobacterium tuberculosis infection and disease progression. However, genomic studies of tuberculosis susceptibility have been disappointing compared with that of other complex disorders. Recently the field has explored alternative strategies to facilitate locus discovery. Results emanating from these efforts during the last 18 months are addressed in this review. RECENT FINDINGS There has been a renewed focus on the refinement of phenotypic definitions of infection and disease as well as on age-related, sex-specific and population-specific effects. Genome-wide association studies have yielded candidate genes but the findings have not always been transferable to all population groups. Candidate gene association studies remain popular as it is used for GWAS replication and is affordable, particularly in lower and middle-income countries. Pharmacogenetic studies involving tuberculosis drugs may locate variants that can be cost-effectively genotyped to identify individuals at risk of developing adverse events during treatment. SUMMARY Additional GWAS and candidate gene association studies of crudely defined study participants are unlikely to make further important contributions to the TB susceptibility field. Instead refined phenotyping will allow the elucidation of genetic mechanisms contributing to infection and disease in distinct populations and the calculation of polygenic risk scores.PURPOSE OF REVIEW MicroRNAs (miRNAs) are small noncoding RNA molecules that are considered one of the fundamental regulatory mechanisms of gene expression. They are involved in many biologic processes, such as signal transduction, cell proliferation and differentiation, apoptosis and stress responses. see more The purpose of this review is to present recent knowledge about the role of miRNAs in asthma and outline possible applications of miRNAs. RECENT FINDINGS A core set of miRNAs involved in asthma includes downregulated let-7 family, miR-193b, miR-375 as well as upregulated miR-21, miR-223, miR-146a, miR-142-5p, miR-142-3p, miR-146b and miR-155. Recently it has been shown that most of the involved miRNAs increase secretion of Th2 cytokines, decrease secretion of Th1 cytokines, promote differentiation of T cells towards Th2 or play a role in hyperplasia and hypertrophy of bronchial smooth muscle cells. The profiles of miRNAs correlate with clinical characteristics, including lung function, phenotype and severity of asthma. SUMMARY Recent publications confirmed crucial regulatory role of miRNAs in the pathomechanism of asthma. Some single miRNAs or their sets hold the promise for their use as asthma biomarkers facilitating diagnosis or prediction of treatment outcomes. They are also possible target of future therapies. The studies in this field are lacking though.PURPOSE OF REVIEW Pulmonary nontuberculous mycobacterial disease (NTM) remains a significant clinical challenge with suboptimal therapy. This review focuses on recent understandings around the pathogenesis of NTM disease and nonantibiotic therapeutic approaches that are being pursued. RECENT FINDINGS The absence of animal models that truly replicate human disease remains a major problem for NTM research with most findings coming from tuberculosis or tuberculosis-like studies. Recent research reiterates the known key roles of interferon gamma (IFNγ), tumor necrosis factor, interleukin-12 and granulocyte-macrophage colony stimulation factor (GM-CSF) in immunity to NTM. Autoantibodies to some of these factors may be important. Recent nonantibiotic research has focused on either boosting the immune response to NTM (e.g. with IFNγ or GM-CSF) or using other compounds to kill these pathogens (e.g. inhaled NO, gallium, etc.). SUMMARY Our poor understanding of the immune deficit leading to NTM disease continues to hinder the development of highly effective therapies. New approaches are promising but need significant validation before being considered viable therapeutic options.PURPOSE OF REVIEW Internet society has made our daily life more convenient, while its negative consequences especially internet, smartphone, and gaming addiction are emerging. At the same time, the phenomenon of pathological social withdrawal called 'hikikomori' has been increasingly highlighted as a problematic behavior in Japan. Now hikikomori is becoming a global mental health issue. The interaction between internet society, internet addiction, and hikikomori has not been well clarified. RECENT FINDINGS A case vignette survey among psychiatrists suggested that hikikomori cases could be comorbid with internet addiction. In reality, hikikomori cases with internet addiction have been reported internationally. A recent survey among college/university students in Japan has indicated positive interactions between internet addiction, smartphone addiction, gaming internet disorder, and hikikomori-tendencies. SUMMARY The cause of hikikomori has not been well understood, and the emergence of internet may be one of the important contributing factors for the occurrence of hikikomori. Whether pathological social withdrawal creates internet addiction, or internet overuse creates hikikomori remains unclear. Both possibilities exist, and we herein propose the conceptual model of these hypothetical interactions. Clarifying the mechanisms of both conditions will help to solve these crucial issues for contemporary urban societies.OBJECTIVES The authors conducted a systematic review of the literature and meta-analyses to assess the influence of family environment on language development in children with cochlear implants. DESIGN The Pubmed, excerpta medica dataBASE (EMBASE), Education Research Information Center, cumulative index to nursing and allied health literature (CINAHL), Healthcare Literature Information Network, PubPsych, and Social SciSearch databases were searched. The search strategy included terms describing family environment, child characteristics, and language development. Studies were included that (a) assessed distal family variables (such as parental income level, parental education, family size, and parental stress) with child language outcomes, and/or more proximal correlates that directly affect the child (such as family engagement and participation in intervention, parenting style, and more specifically, the quantity and quality of parental linguistic input) on child language; (b) included children implanted before the age of 5 years; (c) measured child language before the age of 21 years with standardized instruments; (d) were published between 1995 and February 2018; and (e) were published as peer-reviewed articles.
