BACKGROUND: In recent years, three-dimensional (3D)-printing of tissue-engineered cartilaginous scaffolds is intended to close the surgical gap and provide bio-printed tissue designed to fit the specific geometric and functional requirements of each cartilage defect, avoiding donor site morbidity and offering a personalizing therapy. METHODS: To investigate the role of 3D—bioprinting scaffolding for nasal cartilage defects repair a systematic review of the electronic databases for 3D-Bioprinting articles pertaining to nasal cartilage bio-modelling was performed. The primary focus was to investigate cellular source, type of scaffold utilization, biochemical evaluation, histological analysis, in-vitro study, in-vivo study, animal model used, length of research, and placement of experimental construct and translational investigation. RESULTS: From 1011 publications, 16 studies were kept for analysis. About cellular sources described, most studies used primary chondrocyte cultures. The cartilage used for cell isolation was mostly nasal septum. The most common biomaterial used for scaffold creation was polycaprolactone alone or in combination. About mechanical evaluation, we found a high heterogeneity, making it difficult to extract any solid conclusion. Regarding biological and histological characteristics of each scaffold, we found that the expression of collagen type I, collagen Type II and other ECM components were the most common patterns evaluated through immunohistochemistry on in-vitro and in-vivo studies. Only two studies made an orthotopic placement of the scaffolds. However, in none of the studies analyzed, the scaffold was placed in a subperichondrial pocket to rigorously simulate the cartilage environment. In contrast, scaffolds were implanted in a subcutaneous plane in almost all of the studies included. CONCLUSION: The role of 3D—bioprinting scaffolding for nasal cartilage defects repair is growing field. Despite the amount of information collected in the last years and the first surgical applications described recently in humans. Further investigations are needed due to the heterogeneity on mechanical evaluation parameters, the high level of heterotopic scaffold implantation and the need for quantitative histological data.

Influence of GRIA1, GRIA2 and GRIA4 polymorphisms on diagnosis and response to treatment in patients with major depressive disorder.

Chiesa, Alberto,Crisafulli, Concetta,Porcelli, Stefano,Han, Changsu,Patkar, Ashwin A,Lee, Soo-Jung,Park, Moon Ho,Jun, Tae-Youn,Serretti, Alessandro,Pae, Chi-Un Springer International 2012 European archives of psychiatry and clinical neuro Vol.262 No.4

<P>The present study is aimed to exploring whether some single nucleotide polymorphisms (SNPs) within GRIA1, GRIA2 and GRIA4 could be associated with major depressive disorder (MDD) and whether they could predict clinical outcomes in Korean in-patients, respectively, treated with antidepressants. One hundred forty-five (145) patients with MDD and 170 healthy controls were genotyped for 17 SNPs within GRIA1, GRIA2 and GRIA4. Baseline and final clinical measures, including the Montgomery-Asberg Depression Rating Scale (MADRS) for patients with MDD, were recorded. No association was observed between alleles, genotypes and haplotypes under investigation and clinical and demographical variables. As a secondary finding, a marginal association was observed between rs4302506 and rs4403097 alleles within GRIA2 and age of onset in patients with MDD. Our findings provide evidence for a possible association between rs4302506 and rs4403097 SNPs and age of onset in patients with MDD. However, taking into account that the several limitations of our study including the moderately small sample size of our study, our findings should be considered with caution and further research is needed to draw more definitive conclusions.</P>

Alberto Chiesa,Agnese Marsano,Changsu Han,SooJung Lee,Ashwin A. Patkar,ChiUn Pae,Alessandro Serretti 대한신경정신의학회 2004 PSYCHIATRY INVESTIGATION Vol.1 No.2

The aim of the present work is to investigate the existence of epistatic interactions possibly influencing psychotropic agents’ response between rs6740584 within Cyclic adenosine monophosphate Response Element Binding (CREB) and rs12775799 within cAMP response element-modulator (CREM) variants in bipolar disorder (BD) and major depressive disorder (MDD). All BD and MDD patients were administered with the Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HAMD) at baseline and at endpoint, respectively. A multiple regression model was employed to investigate the existence of possible epistatic interactions between the two variants and diverse clinical factors including drug response in affective disorders. No significant epistatic interaction was observed between rs6740584 within CREB and rs12775799 within CREM on both symptom improvement and other clinical factors in affective disorders. Our preliminary results suggest that no epistatic interaction between rs6740584 within CREB and rs12775799 within CREM should exist on clinical improvement and clinical factors in affective disorders.

No influence of FAT polymorphisms in response to aripiprazole.

Pae, Chi-Un,Chiesa, Alberto,Mandelli, Laura,De Ronchi, Diana,Serretti, Alessandro Springer-Verlag 2010 Journal of human genetics Vol.55 No.1

<P>The aim of this study was to investigate possible influences of a set of markers in the FAT gene (rs2306987, rs2306990, rs2637777 and rs2304865) on efficacy and tolerability of aripiprazole in the treatment of schizophrenic patients. Efficacy was assessed at baseline and weeks 1, 2, 4, 6, 8 and 12 using the Clinical Global Impression Severity and Improvement scale (CGI-S; CGI-I), the Brief Psychiatric Rating Scale and the Schedule for the Assessment of Negative Symptoms scale. Side effects were evaluated by means of the Simpson-Angus Scale for Extrapyramidal Symptoms, the Barnes Akathisia Scale and the Abnormal Involuntary Movement Scale. Multivariate analyses were employed to test possible influences of single nucleotide polymorphisms on clinical and safety variables. Analysis of haplotypes was also performed. No relevant association between FAT variants and clinical or safety scores was observed. Haplotype analysis did not reveal any significant association with clinical and safety scores at any time as well. Our data suggest no association between investigated alleles and genotypes in FAT and response to aripiprazole. However, because several limitations characterize the present study, further investigations on larger studies are required.</P>

Safety and Tolerability of Lamotrigine: Results From 12 Placebo-Controlled Clinical Trials and Clinical Implications

Seo, Ho-Jun,Chiesa, Alberto,Lee, Soo-Jung,Patkar, Ashwin A.,Han, Changsu,Masand, Prakash S.,Serretti, Alessandro,Pae, Chi-Un Lippincott Williams Wilkins, Inc. 2011 Clinical neuropharmacology Vol.34 No.1

The mechanism of action of lamotrigine depends on voltage-sensitive sodium channels by which the neuronal membrane is stabilized and the release of excitatory neurotransmitters, such as glutamate and aspartate, is inhibited. Lamotrigine is indicated for maintenance treatment of bipolar I disorder to delay the time to the occurrence of mood episodes for those treated for acute mood episodes with standard therapy. There are significant gaps between clinical practices and research settings; data from controlled clinical trials of lamotrigine provide essential information about safety in bipolar populations because they result from large samples of patients with a specific disease and include comparisons with placebo or other comparators with randomized designs. In addition, lamotrigine's safety and tolerability data differ slightly in relation to disease entities, age ranges of the patients taking lamotrigine, and treatment conditions. For example, the incidence of serious rashes, including Stevens-Johnson syndrome, is approximately 0.8% (8/1000) in pediatric patients (2-16 years of age) receiving lamotrigine as adjunctive therapy for epilepsy and 0.3% (3/1000) in adults on adjunctive therapy for epilepsy. In clinical trials of bipolar and other mood disorders, the rate of serious rash was 0.08% (0.8/1000) in adult patients receiving lamotrigine as initial monotherapy and 0.13% (1.3/1000) in adult patients receiving lamotrigine as adjunctive therapy.Hence, in this study, we focus on the data regarding the safety and tolerability of lamotrigine in the treatment of bipolar disorder gathered from 12 placebo-controlled trials, regardless of publication status, that were sponsored by GlaxoSmithKline. We also inform clinicians of practical issues in safety and tolerability in the use of lamotrigine in the treatment of bipolar disorders.
