Fibroblasts maintain tissue and organ homeostasis through output of extracellular matrix that affects nearby cell signaling within the stroma. Altered fibroblast signaling contributes to many disease states and extracellular matrix secreted by fibroblasts has been used to stratify patient by outcome, recurrence, and therapeutic resistance. Recent advances in imaging mass spectrometry allow access to single cell fibroblasts and their ECM niche within clinically relevant tissue samples.

We review biological and technical challenges as well as new solutions to proteomic access of fibroblast expression within the complex tissue microenvironment. Review topics cover conventional proteomic methods for single fibroblast analysis and current approaches to accessing single fibroblast proteomes by imaging mass spectrometry approaches. Strategies to target and evaluate the single cell stroma proteome on the basis of cell signaling are presented.

The promise of defining proteomic signatures from fibroblasts and their extracellular matrix niches is the discovery of new disease markers and the ability to refine therapeutic treatments. Several imaging mass spectrometry approaches exist to define the fibroblast in the setting of pathological changes from clinically acquired samples. Continued technology advances are needed to access and understand the stromal proteome and apply testing to the clinic.

Azoles are the first-line antifungal agents used for the treatment of

infection. There is an increasing concern for azole resistance all over the world mainly from agricultural fungicide use. Choosing safe and effective antifungal regimens has become a challenge.

Here, the authors review the epidemiology, mechanisms, and detection of azole resistance along with management options for azole-resistant

infection, including new antifungal agents under development.

Routine global epidemiological surveillance is required to understand azole resistance prevalence. Azole-resistant

infections are associated with high mortality. No good therapeutic options are currently available. High index of suspicion of resistance is required if a patient is not responding to 4-7days of azole therapy, particularly in the areas of resistance. Susceptibility testing for

is not routinely available in many parts of the world, which makes it difficult to diagnose azole resistance in

infection. There are several new antifungal classes with novel mechanisms of action; clinical trials are ongoing.

Intraoperative cholangiotomy, cholangioscopy, and laparoscopic CBD exploration (LCBDE) are techniques that allow removal of stones from the CBD during the index procedure. However, bile leakage following CBD exploration is a common problem. The aim of this study was to assess whether fibrin sealant applied to the duct incision is safe. Methods Patients planned for laparoscopic gallstone surgery at the Department of Surgery, Enköping Hospital, were included in the study. In cases where perioperative cholangiography showed CBD stones, LCBDE was performed through a longitudinal incision in the CBD. Randomization between closure of the incision with polyglactin sutures or with fibrin sealant was performed. TOFA inhibitor chemical structure After all the stones had been removed and the incision closed according to the allocation, an abdominal drain was placed close to the incision. A T tube was placed in the CBD or a straight tube into cystic duct for eventual postoperative cholangiogram. The patient and the surgeon assessing the postoperative course were blinded to the randomized allocation. Results Altogether 51 patients were included from December 2012 to July 2016. Mean operative time was 188 minutes in the fibrin sealant group and 214 minutes in the suture group (P = .159). There was no significant difference between groups in bile flow in the abdominal drainage tube or in the CBD drain during the three first postoperative days. The time to removal of the abdominal drain did not differ significantly between groups. Conclusion Although the present study lacks the statistical power to prove a benefit from fibrin sealant, it indicates that closure of the incision may be an option to reduce the risk for leakage. Further studies are required to confirm this. The study was retrospectively registered on clinicaltrials.gov September 5, 2015 (NCT02545153).BackgroundPresently, there are no national screening programs for cancer in Vietnam. This study aimed to analyze the cost-effectiveness of an annual colorectal cancer (CRC) screening program from the healthcare service provider's perspective for the Vietnamese population.MethodsThe economic model consisted of adecision tree and aMarkov model. Adecision tree was constructed for comparing two strategies, including ascreening group with aguaiac-based fecal occult blood test (gFOBT) and ano-screening group in general populations, aged 50 years and above. The Markov model projected outcomes over a25-year horizon. The cost-effectiveness outcome was the incremental cost-effectiveness ratio (ICER) represented by costs per quality-adjusted life-years (QALYs).ResultsWhen compared with no screening, ICER was $1,388per QALY with an increased cost of $ 43.98 and again of 0.032 QALY (Willingness to pay $2,590). The uptake rate of gFOBT, cost of colonoscopy, and the total cost of screening contributed to the largest impact on the ICER.
