Farnesyl-diphosphate farnesyltransferase 1 (FDFT1, squalene synthase), a membrane-associated enzyme, synthesizes squalene via condensation of two molecules of farnesyl pyrophosphate. Accumulating evidence has noted that FDFT1 plays a critical role in cancer, particularly in metabolic reprogramming, cell proliferation, and invasion. Based on these advances in our knowledge, FDFT1 could be a potential target for cancer treatment. This review focuses on the contribution of FDFT1 to the hallmarks of cancer, and further, we discuss the applicability of FDFT1 as a cancer prognostic marker and target for anticancer therapy.

Purpose In this study, we focused on the role of elevated serum interleukin 6 (IL-6) concentration in predicting 5-year cardiovascular mortality in hemodialysis patients using low-flux dialyzer reuse. Materials and methods We measured serum IL-6 concentrations in 236 hemodialysis patients (138 males and 98 females) to predict 5-year cardiovascular mortality. We assessed the baseline demographics of all patients who had a mean age of 44 years and a median hemodialysis duration of 38.5 months. We divided all patients into two equal groups based on the serum IL-6 concentration: G1 (n = 118) with serum IL-6 concentration < 6.78 pg/L and G2 (n = 118) with serum IL-6 concentration ≥ 6.78 pg/L. Results After the 5-year follow-up, 45 patients died due to cardiovascular causes (19.1%). Lipid disorder, hemoglobin, serum albumin, β2-M, and IL-6 concentration were independent risk factors for predicting cardiovascular mortality during the 60-month follow-up in hemodialysis patients. Based on the Kaplan-Meier analysis, we realized that patients with a higher interleukin 6 concentration (G2) had a significantly higher cardiovascular mortality rate than patients in G1 (log-rank test p < 0.001). Serum IL-6 concentration was a better predictor of 5-year cardiovascular mortality than high-sensitivity C-reactive protein in hemodialysis patients using low-flux dialyzer reuse (AUC = 0.818; p < 0.001; cut-off value: 8.055 pg/ mL, Se = 77.8%, Sp = 78.5%). Conclusion Serum IL-6 concentration was a better predictor of 5-year cardiovascular mortality than high-sensitivity C-reactive protein in maintenance hemodialysis patients using low-flux dialysis reuse.

Fibrinolytic shutdown is associated with poor prognosis in adult sepsis, but data in the pediatric population are sparse. This study aimed to identify the association between impaired fibrinolysis and mortality in pediatric septic shock.

Platinum-based antitumor agents have been widely used to treat head and neck squamous cell carcinoma (HNSCC) and numerous other malignancies. Cisplatin is the most frequently used platinum-based antitumor agent, however drug resistance and numerous undesirable side effects limit its clinical efficacy for cancer patients. Cancer cells discharge cisplatin into the extracellular space via copper transporters such as ATPase copper transporting beta (ATP7B) in order to escape from cisplatin-induced cell death. In the present study, it was demonstrated for the first time that the copper chelator ammonium tetrathiomolybdate (TM) has several promising effects on cisplatin and HNSCC. First, TM suppressed the ATP7B expression in HNSCC cell lines in vitro, thereby enhancing the accumulation and apoptotic effect of cisplatin in the cancer cells. Next, it was revealed that TM enhanced the antitumor effect of cisplatin in HNSCC cell tumor progression in a mouse model of bone invasion, which is important since HNSCC cells frequently invade to facial bone. Finally, it was demonstrated that TM was able to overcome the cisplatin resistance of a human cancer cell line, A431, via ATP7B depression in vitro.

The objective of this study was to assess the availability and readiness of the primary health care (PHC) services of commune health centers (CHCs) in Quoc Oai, a rural district of Northern Vietnam based on the World Health Organization's Service Availability and Readiness Assessment (SARA) tool. The study was done in 2 steps. First, the heads of the 21 CHCs of Quoc Oai district were interviewed using SARA, a quantitative survey, and the responses were then validated by direct observations of each facility. The results showed that although the average number of health staffs in each CHC met the national standards (at least 5 staffs per CHC), its allocation within each CHC was not properly met because some CHCs had only 2 health staffs. Several health equipment and facilities were not fully available in many CHCs, and although the majority of the PHC services were available at the CHCs, their readiness remained limited. Several significant correlates between the availability of health care workers and the availability of the facilities and the PHC services were observed, suggesting that they depend upon and affect one another in the health system. Using the SARA-based inventory, the study helps health managers and policy makers to prioritize efforts and allocate resources more appropriately. To be effective, attention should be given to how to make facilities, services, and human resources for health ready for PHC activities-more investment and support from the system (from higher to lower level) and the government.
