A rare case of isolated trapezium fracture in motorcycle polytrauma patient in emergency department

Abstract Medical staff hardly recognize fractures of trapezium due to the small size and the complex anatomy of the wrist and the hand. Seventy percent of all carpal fractures are scaphoid's fractures. Only 0.4% of all carpal injuries are trapezial fractures. In this paper, we presented a case of a high speed trauma where there were only trapezial fractures. Origin, diagnosis, differential diagnosis, treatment and complications are evaluated and described

Análise dialélica para conteúdos de lisina e óleo em grãos de milho

Six S5 lines of maize, with differences for lysine and oil contents in grains, were used to carry out a complete series of diallelic crosses. The resulting 15 hybrids were grown in a field at two nitrogen levels (10 and 130 kg N ha-1). The general combining ability (GCA) and specific combining ability (SCA) were obtained by using the method 4, model I of Griffing for grain yield, and grain lysine and oil contents. Significant (p < 0.001) interaction was observed between GCA and N levels for grain yield, indicating the selection of different lines for each N level. This interaction was not significant for lysine content, but there were significant effects of GCA for this trait at both N levels (p < 0.1). Significant effects were not observed for GCA or SCA for oil content, however a positive correlation was observed between lysine and oil contents in the hybrids, in the lines and even in the control cultivars. The results indicate the effectiveness of selection for lysine content, irrespective of N level, in the studied non-opaque maize lines, and the possibility of achieving both high lysine and oil content in grains.Seis linhagens S5 de milho, com diferenças para conteúdos de óleo e de lisina nos grãos, foram usadas para realizar uma série completa de cruzamentos dialélicos. Os 15 híbridos resultantes foram cultivados em campo com dois níveis de nitrogênio (10 e 130 kg N ha-1). A capacidade geral de combinação (CGC) e a capacidade específica de combinação (CEC) foram obtidas com o método 4, modelo I de Griffing para produtividade de grãos e concentração de lisina e óleo nos grãos. Interação significativa (p < 0.001) foi observada entre CGC e níveis de N para produtividade de grãos, indicando seleção de diferentes linhagens para cada nível de N. Esta interação não foi significativa para conteúdo de lisina, mas existiu efeito significativo (p < 0.1) da CGC nos dois níveis de N para esta variável. Os efeitos de CGC e CEC foram não significativos para conteúdo de óleo, contudo, foi observada correlação positiva entre conteúdos de lisina e óleo nos híbridos, nas linhagens e mesmo nas cultivares utilizadas como controle. Os resultados indicam a efetividade da seleção para conteúdo de lisina nas linhagens não opaco de milho estudadas, independente dos níveis de N, e a possibilidade de atingir concomitantemente maiores níveis de óleo e lisina nos grãos

Highlighting chromosome loops in DNA-picked chromatin (DPC).

"Growing evidence supports the concept that dynamic intra-and inter-chromosomal links between specific loci contribute to the creation of cell type-specific gene expression profiles. Therefore, analysis of the establishment of peculiar functional correlations between sites, also distant on linear DNA, that govern the transcriptional process appears to be of fundamental relevance. We propose here an experimental approach showing that 17 beta-estradiol-induced transcription associates to formation of loops between the promoter and termination regions of hormone-responsive genes. This strategy reveals as a tool to be also suitably used, in conjunction with automated techniques, for an extensive analysis of sites shared by multiple genes for induced expression.

Long-term, Real-life, Observational Study in Treating Outpatient Ulcerative Colitis with Golimumab

Background and Aims: Several studies have found Golimumab (GOL) effective and safe in the short-term treatment of ulcerative colitis (UC), but few long-term data are currently available from real world. Our aim was to assess the long-term real-life efficacy and safety of GOL in managing UC outpatients in Italy. Methods: A retrospective multicenter study assessing consecutive UC outpatients treated with GOL for at least 3-month of follow-up was made. Primary endpoints were the induction and maintenance of remission in UC, defined as Mayo score ≤2. Several secondary endpoints, including clinical response, colectomy rate, steroid free remission and mucosal healing, were also assessed during the follow-up. Results: One hundred and seventy-eight patients were enrolled and followed up for a median (IQR) time of 9 (3-18) months (mean time follow-up: 33.1±13 months). Clinical remission was achieved in 57 (32.1%) patients: these patients continued with GOL, but only 6 patients (3.4%) were still under clinical remission with GOL at the 42nd month of follow-up. Clinical response occurred in 64 (36.4%) patients; colectomy was performed in 8 (7.8%) patients, all of them having primary failure. Steroid-free remission occurred in 23 (12.9%) patients, and mucosal healing was achieved in 29/89 (32.6%) patients. Adverse events occurred in 14 (7.9%) patients. Conclusions: Golimumab does not seem able to maintain long-term remission in UC in real life. The safety profile was good

Withdrawal of mechanical ventilation in amyotrophic lateral sclerosis patients: a multicenter Italian survey

Background: Law 219/2017 was approved in Italy in December 2017, after a years-long debate on the autonomy of healthcare choices. This Law, for the first time in Italian legislation, guarantees the patient's right to request for withdrawal of life-sustaining treatments, including mechanical ventilation (MV). Objective: To investigate the current status of MV withdrawal in amyotrophic lateral sclerosis (ALS) patients in Italy and to assess the impact of Law 219/2017 on this practice. Methods: We conducted a Web-based survey, addressed to Italian neurologists with expertise in ALS care, and members of the Motor Neuron Disease Study Group of the Italian Society of Neurology. Results: Out of 40 ALS Italian centers, 34 (85.0%) responded to the survey. Law 219/2017 was followed by an increasing trend in MV withdrawals, and a significant increase of neurologists involved in this procedure (p 0.004). However, variations across Italian ALS centers were observed, regarding the inconsistent involvement of community health services and palliative care (PC) services, and the intervention and composition of the multidisciplinary team. Conclusions: Law 219/2017 has had a positive impact on the practice of MV withdrawal in ALS patients in Italy. The recent growing public attention on end-of-life care choices, along with the cultural and social changes in Italy, requires further regulatory frameworks that strengthen tools for self-determination, increased investment of resources in community and PC health services, and practical recommendations and guidelines for health workers involved

Conceptual Design of a Soft X‐ray SASE‐FEL Source

FELs based on SASE are believed to be powerful tools to explore the frontiers of basic sciences, from physics to chemistry to biology. Intense R&D programs have started in the USA and Europe in order to understand the SASE physics and to prove the feasibility of these sources. The allocation of considerable resources in the Italian National Research Plan (PNR) brought about the formation of a CNR‐ENEA‐INFN‐University of Roma "Tor Vergata" study group. A conceptual design study has been developed and possible schemes for linac sources have been investigated, bringing to the SPARX proposal. We report in this paper the results of a preliminary start to end simulation concerning one option we are considering based on an S‐band normal conducting linac with high brightness photoinjector integrated in a RF compressor
