The efficacy and safety of ketamine for depression in patients with cancer: A systematic review

Management of depression in the oncology population includes supportive psychotherapeutic interventions with or without psychotropic medication, which take time to demonstrate effectiveness. Fast-acting interventions, like ketamine, can provide a rapid antidepressant effect; however, there has been limited research on effects of ketamine among cancer patients. The objective of this review is to provide an overview of research on the efficacy and safety of ketamine on depression in patients with cancer. We reviewed the published literature in MEDLINE® (via PubMed®), EMBASE, and Scopus from 1 January 1982 to 20 October 2022. We screened the retrieved abstracts against inclusion criteria and conducted a full-text review of eligible studies. Following extraction of data from included studies, we used a framework analysis approach to summarize the evidence on using ketamine in patients with cancer. All 5 included studies were randomized clinical trials conducted in inpatient settings in China. In all included studies ketamine was administered intravenously. Three studies used only racemic ketamine, and two studies used both S-ketamine and racemic ketamine. All included studies reported ketamine a tolerable and effective drug to control depression symptoms. Included studies showed administration of sub-anesthesia ketamine significantly improves postoperative depression among patients with cancer. [Abstract copyright: © 2023 The Author(s).

Evaluation of Affordability and Impoverishment Effect of Cardiovascular Medicines in Iran: Effect of cardiovascular medicines in Ira

Cardiovascular disease is one of the most important causes of death in the world. There are variety of plans and strategies to treatment and prevention of CVD. Medicines have significant role in reaching the goals. Ensuring affordability of medicines is very crucial to success in these programs. The impoverishment method which focuses on the impoverishing effect of the purchasing of medicines is one of the most popular methods to quantifying affordability of medicines. We applied this method to measure affordability of cardiovascular medicines in Iran. We used two poverty lines 1.25 USD and 2 USD per day which are recommended by World Bank to access the affordability of medicines. Mono therapy with one anti platelet, Beta blocker, ACE inhibitor and Statin as well as combination therapy have been determined. Our study highlighted that the poorest households in Iran would be at risk of pushing under poverty line because of price of the medicines

The efficacy of ketamine for pain management in patients with cancer: A systematic review

Copyright © 2024 American Society of Clinical Oncology. All rights reserved.e24069 Background: Managing cancer-related pain poses significant challenges, prompting research into alternative approaches such as the study of ketamine. This systematic review aims to analyze and summarize the impact of ketamine as an adjuvant to opioid therapy for cancer-related pain. Methods: We conducted a literature review in MEDLINE, EMBASE, and Scopus, spanning from January 1, 1982, to October 20, 2022. Abstracts were screened against inclusion criteria, and eligible studies underwent a thorough full-text review. Data were extracted from the included studies, and a framework analysis approach was employed to summarize the evidence regarding ketamine's use in patients with cancer. The quality of included studies was assessed using the NIH Quality Assessment Tool for controlled intervention studies. Results: A total of 22 studies conducted between 2001 and 2019 were included, all assessed as having good quality. Three studies focusing on intrathecal administration of ketamine following oncological surgery demonstrated a substantial improvement in pain scores and a reduction in postoperative morphine requirements. Two studies exploring intramuscular use concluded that it led to improved pain scores. In contrast, three studies on subcutaneous administration and two studies on topical ketamine did not exhibit a significant impact on reducing pain scores or alleviating chemotherapy-induced peripheral neuropathy. Findings from two studies on oral administration and eight studies on intravenous administration indicated that intravenous ketamine reduced postoperative morphine requirements, while oral ketamine had no discernible effect on lowering pain scores. Conclusions: The use of intrathecal ketamine demonstrates significant improvement in post-op oncological pain and refractory cancer pain, resulting in lowered pain scores and decreased morphine requirements. Further research is essential to ascertain the extent to which incorporating ketamine with opioids in cancer pain treatment can enhance pain outcomes, especially in morphine-tolerant patients
