TREATMENTS FOR ACUTE LYMPHOBLASTIC LEUKEMIA: A COMPARISON BETWEEN TISAGENLECLEUCEL AND CLOFARABINE

Background: Acute lymphoblastic leukemia (ALL) is a heterogeneous hematological malignancy predominantly affecting individuals under 20 years of age. Traditional chemotherapy, such as clofarabine, has shown efficacy; however, novel immunotherapeutic strategies like tisagenlecleucel (Kymriah®) have significantly altered the treatment paradigm. Aim: This study aimed to perform a comparative analysis of tisagenlecleucel, a CAR-T cell therapy, and clofarabine, a second-generation purine nucleoside analog, evaluating their mechanisms of action, therapeutic benefits, limitations, and clinical applicability across diverse patient populations. Methods: A systematic comparative evaluation was conducted, encompassing pharmacological characteristics, mechanisms of action, treatment protocols, efficacy, safety profiles, and clinical indications of both agents. The analysis considered pharmacokinetic and pharmacodynamic data and included patient demographic variables. Results: Tisagenlecleucel demonstrated high efficacy in refractory B-cell ALL, with durable responses and a blood half-life of 128 days, but with notable immune-related adverse effects such as cytokine release syndrome. Clofarabine, effective across a broader patient population, acts via multiple antitumor mechanisms but carries significant toxicity risks, including infection and sepsis. Discussion: The therapies present distinct clinical profiles: tisagenlecleucel offers targeted immunotherapy with high specificity but requires specialized infrastructure and management of immune toxicities. Clofarabine is more widely accessible and applicable, but is associated with conventional chemotherapy-related side effects. Treatment accessibility and cost differ markedly between the two. Conclusions: Therapy selection should be personalized based on patient-specific factors and institutional resources. Tisagenlecleucel is ideal for pediatric and young adult patients with relapsed/refractory B-cell ALL in CAR-T-capable centers, while clofarabine remains a viable option for broader ALL populations, particularly when genetic therapies are not feasible. Further research is needed to optimize therapeutic strategies and improve access to advanced treatments.

THE ROLE OF THE MEDITERRANEAN DIET IN PREVENTING MALE INFERTILITY: AN INTERVIEW WITH DR. MIGUEL FORNES (US-EN VERSION)

Background: Dr. Miguel Fornes is a researcher at CONICET and director of the Andrological Research Laboratory of Mendoza, Argentina. His research focuses on how dietary fat excess and hypercholesterolemia affect sperm physiology and male fertility. Objectives: The primary objective of Dr. Fornes' research is to investigate the effects of a high-fat diet on sperm function, capacitation, acrosomal reaction, and fertilization. He aims to develop translational animal models to study these effects without using human subjects. Methods: Dr. Fornes and his team use rabbit models to induce hypercholesterolemia through a high-fat diet. They then study the physiology and function of sperm cells from these hypercholesterolemic rabbits. Key parameters analyzed include cholesterol content in sperm membranes, ability to undergo capacitation and acrosomal reaction, and fertilization capability. Results: The studies revealed that hypercholesterolemia caused by a high-fat diet leads to increased cholesterol levels in sperm. This interferes with the normal physiology of sperm cells. In particular, many sperm from hypercholesterolemic rabbits were unable to properly undergo the acrosomal reaction, a crucial step for successful fertilization of the oocyte. This suggests high-fat diets could contribute to male infertility. Conclusions: The research highlights the importance of diet and lifestyle on male reproductive health. Dr. Fornes recommends a balanced diet like the Mediterranean diet, rich in fruits, vegetables, and olive oil, to maintain healthy sperm function and fertility. Replacing animal fats with olive oil may help prevent hypercholesterolemia-related infertility. The findings have implications for dietary guidelines and clinical interventions to support male fertility.

MISUSE AND ABUSE OF DRUGS: A CROSS-SECTIONAL SURVEY AMONG PHARMACY PROFESSIONALS IN SAUDI ARABIA

Prescription and non-prescription medication misuse or abuse is a global problem that has a negative impact on all human life aspects, including health, social, economic, and security status. According to the United Nations Office on Drug and Crime reports, over 5% of adult people used drugs at least once in the year 2015, and 29.5 million of them were suffered from the consequences of inappropriate use of drugs. Information on the knowledge and perception among pharmacists regarding the misuse and abuse medications in Saudi Arabia are limited, and therefore, a study was conducted among pharmacy staff to assess their knowledge and awareness on drug misuse and abuse. A cross-sectional study was carried out in Eastern Province, Saudi Arabia. Pharmacy professionals with more than three months of experience were included in the study. A structured questionnaire was used to obtain the participant's responses. A Chi-square test was used to evaluate the association of sociodemographic factors with the participant's responses. Ninety pharmacy professionals were responded. Overall, 69 (76.7%) participants agreed that misuse and abuse are two different terms. In addition, the study showed different responses for patients who suspected to be medication abusers. In conclusion, this study provides an initial picture of pharmacy staffs' knowledge and opinion regarding the misuse and abuse of medicines in Saudi Arabia. Participants' reactions toward such behaviors were different and not consistent. Therefore, there should be a clear policy to define the role of the pharmacy staff toward the misuse and abuse of medication in Saudi Arabia.

A COMPARATIVE STUDY ON THE RESPONSES OF TWO LINES OF SUGAR BEET (Beta vulgaris L) TO SALINITY

Sugar beet is a crop able to resist high levels of soil salinity after emergence and establishment. Considering the significant difference in the effect of nitrogen forms on sugar beet performance under normal conditions, the form of nitrogen may affect the performance of sugar beet plants under abiotic stress, particularly salinity. Additionally, exploring the most appropriate type of nitrogen for sugar beet could mean optimizing sucrose content. Therefore, here using two lines, sugar beet was grown in pots (filled with 4 kg soil), salt-resistance (line 7233- p.29 x Mst), and salt-sensitive (line 3929-21939), the effect of two different forms of nitrate in the form of calcium nitrate (1 g per pot) and ammonium in the form of ammonium sulfate (1 g per pot) under normal and salt stress condition (40 Millimoles per liter sodium chloride) were evaluated. The result revealed the positive influence of nitrate over ammonium by indicating higher dry weight in both sensitive line: 19.2 and 13.6 g, and tolerance line: 20.4 and 13.6 g, respectively alone and in combination with salinity stress. Similarly, root yield levels positively influenced by nitrate treatment either alone or under salinity stress (sensitive line: 194.5 and 243.2 g and tolerance line: 207 and 249.5 g). The outcomes additionally showed the accumulation of proline aerial parts in both lines, and however, the proline accumulation of sensitive line was higher (3.9 mg/g dry weight). Moreover, induction of proline aggregation was considerably higher in nitrate nitrogen-treated sensitive line (9.3 mg/g dry weight). The absence of significant difference was obseved between nitrogen treatments in terms of extractable sucrose and root molasses sugar. Also, the root impurities increased in those treated with nitrate-nitrogen and salinity. It can be concluded that nitrate-nitrogen has improved the performance of both sugar beet lines against salinity stress, and its practical application is adviseable.
