Q: THE AIM OF THE STUDY WAS: Is primary Arterio-venous fistula the vascular access of choice for adequate dialysis and better patient outcome in end stage renal disease.', 'The present study was done in the department of cardiovascular and thoracic surgery at Sher-i-Kashmir institute of medical sciences, Soura, Srinagar Kashmir. Native Arterio-Venous (AV) fistulas were made in the patients with end stage renal disease for performing hemodialysis. They were followed for patency and adequacy of blood flow during hemodialysis. All the patients were operated under local anesthesia.', 'The results showed that 77% of the AV fistulas based on radial artery with side-to-side anastomosis and 80% of those with end-to-side anastomosis were functionally patent after one year. After two years, the patency rate in side-to-side and end-to-side anastomosis was 50% and 55%, respectively. In addition, the patency rate was 90% in brachial artery based AV fistula with end-to-side anastomosis, whether done primarily or secondarily, at the end of one year. However, a rapid decline was observed in the patency rate during the third year in both radial artery based and brachial artery based AV fistulas.

Q: Gastric cancer (GC) is widely associated with chronic inflammation. The pro inflammatory microenvironment provides conditions that disrupt stem/progenitor cell proliferation and differentiation. The signal transducer and activator of transcrip- tion-3 (STAT3) signaling pathway is involved in inflammation and also contributes to the maintenance of embryonic stem cell (ESCs) pluripotency. Here, we have investi- gated the activation status of STAT3 in GC stem-like cells (GCSLCs).', 'In this experimental research, CSLCs derived from the human GC cell line MKN-45 and patient specimens, through spheroid body formation, character- ized and then assayed for the STAT3 transcription factor expression in mRNA and protein level further to its activation.', 'Spheroid cells showed higher potential for spheroid formation than the pa- rental cells. Furthemore, stemness genes NANOG, c-MYC and SOX-2 were over expressed in spheroids of MKN-45 and in patient samples. In MKN-45 spheroid cells, epithelial mesenchymal transition (EMT) related markers CDH2, SNAIL2, TWIST and VIMENTIN were upregulated (P<0.05), but we observed no change in expression of the E-cadherin epithelial marker. These cells exhibited more resistance to docetaxel (DTX) when compared with parental cells (P<0.05) according to the MTS assay. Al- though immunostaining and Western blotting showed expression of the STAT3 pro- tein in both spheroids and parents, the mRNA level of STAT3 in spheroids was higher than the parents. Nuclear translocation of STAT3 was accompanied by more intensive phospho-STAT3 (p-STAT3) in spheroid structures relative to the parent cells accord- ing to flow cytometry analysis (P<0.05).

Q: Spontaneous bacterial peritonitis (SBP) is associated with high mortality. Early paracentesis (EP) is essential for rapid diagnosis and optimal treatment. The aim of the study is to compare the outcomes of patients with SBP who received EP vs. delayed paracentesis (DP).', 'Consecutive patients who were diagnosed with SBP (ascites neutrophil count ≥250 cells/mm(3) and clinical evidence of cirrhosis) <72\u2009h from the first physician encounter at two centers were identified. EP was defined by receiving paracentesis <12\u2009h and DP 12-72\u2009h from hospitalization. Primary outcome was in-hospital mortality.', 'The mean age of 239 patients with SBP was 53±10 years; mean Model for End-Stage Liver Disease (MELD) score was 22±9. In all, 98 (41%) patients who received DP had a higher in-hospital mortality (27% vs. 13%, P=0.007) compared with 141 (59%) who received EP. Furthermore, DP group had longer intensive care days (4.0±9.5 vs. 1.3±4.1, P=0.008), hospital days (13.0±14.7 vs. 8.4±7.4, P=0.005), and higher 3-month mortality (28/76, 37% vs. 21/98, 21%; P=0.03) compared with the EP group. Adjusting for MELD score ≥22 (adjusted odds ratio (AOR)=5.7, 95% confidence interval (CI)=1.8-18.5) and creatinine levels ≥1.5\u2009mg/dl (AOR=3.2, 95% CI=1.4-7.2), DP was associated with increased in-hospital mortality (AOR=2.7, 95% CI=1.3-4.8). Each hour delay in paracentesis was associated with a 3.3% (95% CI=1.3-5.4%) increase in in-hospital mortality after adjusting for MELD score and creatinine levels.
