Cost-effectiveness of Ribociclib in HER2- negative breast cancer: A synthesis of current evidence.

Background: The main aim of this study was to investigate the cost-effectiveness of Ribociclib in the treatment of patients with breast cancer by assessing the published evidence. Method: A systematic review of the published literature was conducted to identify the economic evaluations/cost-effectiveness study of Ribociclib. In this study, several databases were inspected, including PubMed, NHS Economic Evaluation, Cochran, and Scopus. Studies were eligible if they assessed the cost-effectiveness of Ribociclib and reported incremental cost-effectiveness ratio (ICER). The study was performed and conducted following the PRISMA reporting guidelines. Results: Of 70 studies identified, 8 articles meet our inclusion criteria. The cost-effectiveness threshold varied from $24,144.18 in Spain to $198,000/QALY in the USA. Moreover, the result demonstrated that the mean ICER varied across different countries $1,863.47/QALY in Spain and $813,132/QALY in the USA. Conclusion: Among all CDK4/6 inhibitors medications, current evidence indicated that the use of Ribociclib for HER2- negative breast cancer management was beneficial and considered to be cost-effective. Future research is needed to investigate the role of Ribociclib in long-term treatment.

Serum Metabolomic Analysis of Male Patients with Cannabis or Amphetamine Use Disorder.

Studies have demonstrated that chronic consumption of abused drugs induces alterations in several proteins that regulate metabolism. For instance, methamphetamine exposure reduces glucose levels. Fatty and amino acid levels were altered in groups exposed to abused drugs. Therefore, in our study, we investigated the serum metabolomic profile of patients diagnosed with cannabis and/or amphetamine use disorders. Blood was obtained from subjects (control, amphetamine, and cannabis). Detection of serum metabolites was performed using gas chromatography. The ratio peak areas for metabolites were analyzed across the three groups. Both cannabis and amphetamine groups showed higher d-erythrotetrafuranose, octadecanoic acid, hexadecenoic acid, trans-9-octadecanoic acid, lactic acid and methyl thio hydantoin metabolites compared with the control group. Moreover, cannabis patients were found to possess higher glycine, 9,12 octadecanoic acid malonic acid, phosphoric acid and prostaglandin F1a than controls. Our analysis showed that the identified metabolic profile of cannabis or amphetamine use disorder patients was different than control group. Our data indicated that chronic exposure to cannabis or amphetamine dysregulated metabolites in the serum. Future studies are warranted to explore the effects of these abused drugs on the metabolic proteins.

Lepidium sativum as candidate against excitotoxicity in retinal ganglion cells.

Glutamate excitotoxicity is considered one of the major causes of retinal ganglion cell death in many retinal diseases. Retinal ganglion cell degeneration causes severe blindness since visual signals from the eye to the brain are conducted only through retinal ganglion cells. OBJECTIVE: We aimed to explore the potential ameliorative effects of L. sativum against glutamate excitotoxicity-induced retinal ganglion cell damage. METHODS: Pure retinal ganglion cells were divided into a control group (untreated); L. sativum-treated groups in which retinal ganglion cells were treated with 5, 10, 50, or 100 µg/mL L. sativum seed extract for 2 h; glutamate-treated groups in which cells were treated with 5, 10, 50, or 100 µM glutamate for 48 h; and L. sativum/glutamate groups [pretreatment with L. sativum for 2 h (50 or 100 µg/mL) before glutamate treatment at 100 µM for 48 h]. Cell damage was assessed by comet assay and cell viability was by MTT test. RESULTS: Tailed DNA, tail length, and tail moment of the 50 and 100 mM glutamate-treated groups were significantly greater than those of the blank control group, while the L. sativum-treated groups demonstrated nonsignificantly different tailed DNA, tail length, and tail moment compared with the blank control group, but significantly lower values compared with the glutamate-treated groups. CONCLUSION: L. sativum ameliorated the cell viability in retinal ganglion cells after high-concentration glutamate exposure. L. sativum seed extracts were efficient anti-excitotoxic and antioxidant agent that might improve the clinical presentation of many neurological disorders.
