Pancreatic cancer has the highest mortality amongst all major organ cancers. Early detection is key to reduce deaths related to pancreatic cancer. However, early detection has been challenged by the lack of non-invasive biomarkers with enough sensitivity and specificity to allow for screening. The gold standard is still carbohydrate antigen (CA 19-9), against which all new biomarkers must be evaluated. In this paper, we describe recent progress in the development of new pancreatic cancer biomarkers, focusing on proteins, metabolites, and genetic and epigenetic biomarkers. Although several promising biomarkers have been identified, they are all derived from retrospective studies and additional prospective studies are needed to confirm their clinical validity.Purpose Patients presenting with lymphovascular space invasion (LVSI) had an absolute decrease in survival. In our present study, the potential roles of LVSI on tumor characteristics was explored to predict the difference in the prognosis of ER and HER2 positive T1 tumors. Methods A total of 142 breast cancer patients diagnosed with ER+ and HER2+ tumors whose tumor size was ≤ 2 cm were included in this analysis. One hundred forty-two patients were divided into four groups, group 1 (lymph nodes+ and LVSI+), group 2 (lymph nodes+ and LVSI-), group 3 (lymph nodes- and LVSI+), group 4 (lymph nodes- and LVSI-). Univariate and multivariate Cox proportional hazard models were used to identify independent prognostic factors and calculate the HR and 95% CI. Kaplan-Meier and Cox regression models were used to test the prognostic significance. Results LVSI positivity was significantly associated with patient age, menopausal status, tumor size, lymph node status, Ki67, PR, and tumor grade. In the univariate and multivariate model, LVSI, PR, and Ki67 were significantly associated with DFS, and LVSI, lymph node status, PR, and Ki67 were significantly associated with OS. LVSI was significantly related to increased risk of DFS and OS only in the PR-negative and low-positive subgroups. It was a prognostic factor for DFS but not for OS in women with low Ki67 and was associated with DFS and OS in high-Ki67 tumors. Furthermore, patients who presented with only LVSI had a significantly worse survival rate than those with lymph node metastasis without LVSI in small tumors. Conclusion The presence of LVSI was highlighted as a variable significant to survival. In further clinical practice, patients with LVSI may need more intensive treatment in certain populations.Background Emerging evidence indicates a regulatory role of long non-coding RNAs (lncRNAs) in the development of gastric cancer (GC), but the mechanisms underlying their function have remained largely unknown. Recent microarray-based expression profiling has led to the identification of a novel differentially expressed lncRNA, LINC00858, in GC. Subsequently, LINC00858 was found to be highly expressed in GC tissues and cells. This study was designed to clarify the functional role of LINC00858 in GC, including its effect on methylation of the WNK2 gene promoter and its downstream MAPK signaling pathway. Methods After exogenous over-expression and knockdown of LINC00858 and the addition of a MAPK pathway inhibitor in GC cells, we explored the effects of LINC00858 and the MAPK signaling pathway on GC cell behavior using various in vitro and in vivo assays. Results LINC00858 was found to negatively regulate WNK2 expression by enhancing its promoter methylation and to activate the MAPK signaling pathway. Moreover, we found that knockdown of LINC00858 or inhibition of the MAPK signaling pathway resulted in decreased GC cell growth, migration and invasion, as well as decreased cell cycle progression, along with increased apoptosis and decreased tumorigenicity. Conclusions Together, these findings indicate that silencing of LINC00858 increases WNK2 expression and inhibits the MAPK signaling pathway, thereby inhibiting GC growth and development. Our data highlight LINC00858 as a potential target in GC therapy.Bimatoprost implant (Durysta™), developed by Allergan, is a sustained-release drug delivery system containing bimatoprost, a prostaglandin analogue with ocular hypotensive activity. The implant, administered intracamerally, involves the use of a biodegradable, solid polymer drug delivery system for slow, sustained drug release, designed to lower intraocular pressure (IOP) over a 4- to 6-months period. In March 2020, bimatoprost implant received its first approval, in the USA, for use to reduce IOP in patients with open angle glaucoma (OAG) or ocular hypertension (OHT). Allergan's clinical development programme for bimatoprost implant is ongoing. This article summarizes the milestones in the development of bimatoprost implant leading to this first approval for use in the reduction of IOP in patients with OAG or OHT.Purpose Bariatric surgery is the most effective treatment for morbid obesity. In association with dietary restrictions, the ability to exercise in the immediate post-surgical phase is limited. In this context, whole-body electromyostimulation (WB-EMS), strategy that stimulates various muscle groups, in conjunction with physical exercise, holds promise for improving functional capacity, and cardiac autonomic control, following surgery. The purpose of this study was to analyze whether a rehabilitation program consisting of WB-EMS with 30 exercise training sessions following bariatric surgery significantly improves functional capacity, body mass and heart rate variability (HRV). Methods Randomized, double-blind, and sham-controlled trial. Twenty obesity patients were randomized into the WB-EMS (n = 10) and sham (n = 10) groups. LY2109761 clinical trial On average, 7 days after surgery, individuals underwent a six-minute walk test (6MWT), HRV, and body composition analysis at rest. The next day, patients initiated an exercise training protocol, five times per week, over 6 weeks. Walking distance changes (post-pre = ΔWD) obtained by 6MWT and HRV indices were determined following the intervention. Results Only WB-EMSG significantly increased WD and body mass index (BMI) after the intervention (p = 0.002) and ΔWD was significantly higher in this group when compared with sham (p = 0.04). Moreover, both groups demonstrated an improvement in key measures of HRV after the intervention. Conclusion An exercise training intervention initiated shortly after bariatric surgery improved functional capacity and cardiac autonomic tone. Improvements in functional capacity and BMI following exercise training were greater with the addition of WB-EMS but did not promote additional improvements in HRV beyond that realized with exercise training alone.
