Are the GLIM Criteria Guiding in the Course of Hematological Malignancies?

BACKGROUND: Different degrees of malnutrition are seen in patients with hematological malignancies. None of the approaches used to determine malnutrition risk have general acceptance. The use of the GLIM criteria developed by the Global Leadership Initiative on Malnutrition has promising results. MATERIALS AND METHODS: A total of 67 patients with leukemia, lymphoma, and multiple myeloma were included in the study. NRS-2002 (Nutritional Risk Screening-2002) was used to screen the nutritional status of the patients, and malnutrition was diagnosed and graded using the GLIM criteria in patients who were found to be at risk of malnutrition in this test. The parameters followed in the groups with and without malnutrition were compared. The Kolmogorov-Smirnov, Mann-Whitney U, and Chi-square test were used for statistical analysis. RESULTS: Patients were analyzed by dividing them into two groups as those with and without malnutrition. The presence of infection, duration of fever, antibiotic, and antifungal use were significantly higher in malnourished than in nonmalnourished patients. Platelet counts and sodium levels were significantly lower in the malnourished arm. CONCLUSION: Early nutritional support can increase the immunological status of patients with malignant disorders as well as their tolerability to treatment. Minimizing the risk of malnutrition and providing timely calorie and vitamin support are factors that may directly affect febrile neutropenia, duration of fever, and antifungal use, which will consequently lead to a decrease in the length of hospitalization.

Real world results of venetoclax combined with hypomethylating agents in relapsed/refractory AML.

OBJECTIVE: Relapsed/refractory AML cases are much more resistant to chemotherapy. Venetoclax is a highly sensitive BCL-2 inhibitor. It was aimed to evaluate the effects of venetoclax therapy on real-world R/R AML survival outcomes, the effects of the cytogenetic characteristics of the patients and previous clinical applications on treatment response, and venetoclax treatment toxicity. PATIENTS AND METHODS: The study included patients who only received a venetoclax-based salvage on R/R AML patients from Turkey. The study included a total of 62 patients from 6 different centers in Turkey. Response to 2 cycles of venetoclax treatment was assessed by bone marrow blast rate. The demographic data, cytogenetic characteristics, AML type, MDS type, response rates and overall survival of the patients after venetoclax combination treatment were assessed. Median age of the patients was 65 (19-85). Mean number of prior treatments was 2.67 ±1.75. RESULTS: 13 patients (21%) had a history of allogenic stem cell transplantation. 58 (93.5%) had received HMA therapy before venetoclax. 36 patients (58.1%) had de-novo AML, and 25 (40.3%) previously had MDS. Treatment response was evaluated as complete remission (n = 21, 33.9%), partial response (n = 17, 27.4%), and treatment failure (n = 24, 38.7%). Patients in the TF group were significantly more likely to have poor cytogenetic and to have received allogeneic transplants. The mean estimated overall survival after the venetoclax treatment was 9.13 ± 0.75 months. CONCLUSIONS: The study population consisted of a group of patients who had relapsed or primary refractory disease with poor prognosis, despite numerous rounds of chemotherapy. It is our belief that the high response rates obtained with the combination of venetoclax/HMA, and having obtained positive results with poor risk patients, indicated a promising perspective for R/R AML patients.

Antioxidant and enzyme-inhibitory activity of peppermint extracts and essential oils obtained by conventional and emerging extraction techniques.

Peppermint is widely used medicinal plant with distinguished bioactive potential, therefore, the aim of present work was to develop novel peppermint extracts with high activity by application of traditional and emerging separation techniques. Conventional hydrodistillation and microwave-assisted hydrodistillation (MWHD) were applied for recovery of essential oil (EO), while organic solvent extraction using Soxhlet apparatus, microwave-assisted and ultrasound-assisted process and supercritical fluid extraction (SFE) were applied for non-selective recovery of peppermint lipophilic extracts. Extracts were characterized in terms of terpenoids profile with special emphasis on content of major compounds (mentol, menthone, isomenthol and eucalyptol). Antioxidant activity (DPPH, ABTS, CUPRAC, FRAP, chelating and phosphomolybdenum assay) and enzyme-inhibitory assays (acetylcholinesterase, butyrylcholinesterase, tyrosinase, amylase and glucosidase inhibition) were used for screening of peppermint bioactivity. MWHD was recognized as alternative for traditional process in EO recovery, while SFE extracts were useful for green production of solvent-free peppermint extracts rich in terpenoids and other lipophilic bioactives.
