MicroRNA profiling of cisplatinresistant oral squamous cell carcinoma cell lines enriched withcancer-stem-cell-like and epithelial-mesenchymal transition-type features
Oral cancer is of major public health problem in India. Current investigation was aimed to identify
the specific deregulated miRNAs which are responsible for development of resistance phenotype
through regulating their resistance related target gene expression in oral squamous cell carcinoma
(OSCC). Cisplatin-resistant OSCC cell lines were developed from their parental human OSCC cell lines
and subsequently characterised. The resistant cells exhibited enhanced proliferative, clonogenic
capacity with significant up-regulation of P-glycoprotein (ABCB1), c-Myc, survivin, β-catenin and a
putative cancer-stem-like signature with increased expression of CD44, whereas the loss of E-cadherin
signifies induced EMT phenotype. A comparative analysis of miRNA expression profiling in parental
and cisplatin-resistant OSCC cell lines for a selected sets (deregulated miRNAs in head and neck cancer)
revealed resistance specific signature. Moreover, we observed similar expression pattern for these
resistance specific signature miRNAs in neoadjuvant chemotherapy treated and recurrent tumours
compared to those with newly diagnosed primary tumours in patients with OSCC. All these results
revealed that these miRNAs play an important role in the development of cisplatin-resistance mainly
through modulating cancer stem-cell-like and EMT-type properties in OSCC

Diagnosis and Management of Intraoperative Colorectal Anastomotic Leaks: A Global Retrospective Patient Chart Review Study
Background. This targeted chart review study reports the first ever detailed global account of clinical approaches adopted to detect and manage anastomotic leaks identified during surgery in routine clinical practice. Method. 156 surgeons from eight countries retrospectively extracted data from surgical records of 458 patients who underwent colorectal surgery with an identified intraoperative leak at the circular anastomosis. Demographic details, procedures, and outcomes were analyzed descriptively, by country. Results. Most surgeries were performed laparoscopically (57.6%), followed by open surgeries (35.8%). The burden of intraoperative leaks on the healthcare system is driven in large part by the additional interventions such as using a sealant, recreating the anastomosis, and diverting the anastomosis to a colostomy bag, undertaken to manage the leak. The mean duration of hospitalization was 19.9 days. Postoperative anastomotic leaks occurred in 62 patients (13.5%), most frequently 4 to 7 days after surgery. Overall, country-specific differences were observed in patient characteristics, surgical procedures, method of diagnosis of intraoperative leak, interventions, and length of hospital stay. Conclusion. The potential cost of time and material needed to repair intraoperative leaks during surgery is substantial and often hidden to the healthcare system, potentially leading to an underestimation of the impact of this complication
