Serpine1 mRNA confers mesenchymal characteristics to the cell and promotes CD8+ T cells exclusion from colon adenocarcinomas.

Serine protease inhibitor clade E member 1 (SERPINE1) inhibits extracellular matrix proteolysis and cell detachment. However, SERPINE1 expression also promotes tumor progression and plays a crucial role in metastasis. Here, we solve this apparent paradox and report that Serpine1 mRNA per se, independent of its protein-coding function, confers mesenchymal properties to the cell, promoting migration, invasiveness, and resistance to anoikis and increasing glycolytic activity by sequestering miRNAs. Expression of Serpine1 mRNA upregulates the expression of the TRA2B splicing factor without affecting its mRNA levels. Through transcriptional profiling, we found that Serpine1 mRNA expression downregulates through TRA2B the expression of genes involved in the immune response. Analysis of human colon tumor samples showed an inverse correlation between SERPINE1 mRNA expression and CD8+ T cell infiltration, unveiling the potential value of SERPINE1 mRNA as a promising therapeutic target for colon tumors.

Efficacy of Sacral Nerve Stimulation in Non-constipated Irritable Bowel Syndrome Patients: A Systematic Review.

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is a prevalent disorder with a complex and heterogeneous physiopathology, including a dysregulation of gut-brain axis. Treatment for IBS is targeted to the predominant symptom and requires a multidisciplinary approach. This review aims to evaluate the efficacy and safety of sacral nerve stimulation in non-constipated IBS patients Methods: A literature search was carried out on MEDLINE, The Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science databases for all relevant articles. Quality of included papers was assessed using standardized guidelines Results: Of 129 initial citations, 7 articles met our predefined inclusion criteria, including five randomized trials, a pilot study and a descriptive follow-up study. Five of 7 studies reported a positive effect of sacral nerve stimulation on symptoms and quality of life improvement in non-constipated IBS patients. No study reported serious adverse events. CONCLUSIONS: Despite initial promising results of sacral nerve stimulation in non-constipated IBS patients, studies with larger sample sizes and longer follow-up are required.

Association of Negative Pressure Wound Therapy and Dermatotraction for Management of Necrotizing Soft Tissue Infections: A Case Series.

INTRODUCTION: Soft tissue infections (STIs), which include infections of the skin, subcutaneous tissue, fascia, and muscle, encompass a wide variety of heterogeneous pathologies. Treatment of STIs is based on surgical debridement of the affected area. One such treatment, negative pressure wound therapy (NPWT), has improved the management of STIs. OBJECTIVE: The purpose of this study is to assess the safety and utility of NPWT in conjunction with dermatotraction in the early stage management of necrotizing STIs. MATERIALS AND METHODS: The authors report a retrospective series of 3 cases in which NPWT and dermatotraction (NPWT-D) were used in an attempt to manage necrotizing STI. The NPWT-D device combination was employed to approximate the edges of the wounds. The NPWT device was changed every 2 or 3 days, and dermatotraction tension was adjusted concurrently. RESULTS: The NPWT-D device changes ranged from 3 to 4 times for 2 of the 3 patients, as 1 patient passed away secondary to STIs and therefore did not receive complete treatment. The total treatment ranged from 8 to 10 days in the remaining 2 patients. In both cases, complete wound closure was achieved while avoiding skin grafts. After 5 days of therapy in the incomplete treatment case, the wound area was reduced by about half. CONCLUSIONS: Based on the experiences herein, NPWT-D may be a safe and useful alternative surgical treatment for the management of necrotizing STIs. In the present cases, NPWT-D improved and shortened the wound healing process, and it achieved a tertiary wound closure, thereby avoiding the need for skin grafts.
