Abstract Lung cancer is one of the most prevalent forms of cancer in patients in Ukraine. The objective of the study was to identify the main problems in the quality of life of patients with lung cancer in order to optimize medical care for this patient group. A survey of 411 patients of oncology institutions in nine regions of Ukraine was conducted in the period from November 2021 to February 2022. The sociological survey was performed using the EORTC QLQ-C30 and QLQ-LC29 questionnaires. As of the pre-war period, the quality of life of lung cancer patients in Ukraine amounted to 49.12 points on a 100-point scale. According to the QLQ-C30 symptom scale, the highest score among the complaints of Ukrainian patients is that of financial difficulties, the second place is occupied by fatigue. According to the QLQ-LC29 symptom scale, patients with lung cancer were most concerned with “Fear of progression”. Ukrainian patients were least concerned about diarrhea and hemoptysis. When providing medical care to cancer patients, components to ensure the proper quality of their lives and psychosocial care, including the standardization of psychological care and its introduction in all institutions that provide medical care to cancer patients; organization of social and psychological support for cancer patients and their families; as well as educational work with relatives, colleagues, medical professionals on awareness of the need for social and psychological support for patients must be taken into account.

Abstract Alzheimer’s disease (AD) is a neurodegenerative disease manifested with accumulation of neurotoxic proteins like beta-amyloid (Aβ) and hyperphosphorylated tau. Administration of angiotensin receptor blockers (ARBs) such as Telmisartan has demonstrated to generate significant memory improvement in AD. Azilsartan is an ARB with better bioavailability than Telmisartan. Hence, the present work evaluates the efficacy of Azilsartan against aluminium chloride (AlCl 3 ) induced AD. In the work, albino rats were divided into five groups (n=6). Group I served as control and received saline (10 ml/kg). Group-II was treated with AlCl 3 (100 mg/kg) for 42 days; Group-III and IV received Azilsartan (5 mg/kg) and Telmisartan (10 mg/kg) with AlCl 3 daily for 42 days. Y-maze, elevated plus maze and radial arm maze were used to evaluate memory functions. This was followed by biochemical and histological studies, along-with determination of Aβ content and anti-oxidant status. AlCl 3 was found to significantly (p <0.05) reduce cognition and increased concentration of Aβ in a hippocampus with elevated lipid peroxidation levels. It also significantly (p<0.05) decreased superoxide dismutase and increased malondialdehyde content. However, brain histology showed presence of neurofibrillary tangles, neuronal dead cells, and pyknotic cells compared to normal group. Still, Azilsartan and Telmisartan significantly (p<0.05) reversed cognitive dysfunction, improved antioxidant status and decreased Aβ production. Thus we conclude that Azilsartan protects AlCl 3 induced AD-like pathology but, to a degree less than Telmisartan.

Abstract Introduction. Hypothyroidism is a common endocrine disorder that affects millions of people worldwide. The diagnosis and monitoring of this condition often rely on thyroid hormone levels, which can be limited in their accuracy. Pentraxin 3 (PTX3) is a protein family that is involved in the innate immune response and is distinguished by its distinct pentameric structure. Aim. To evaluate the utility of serum PTX3 levels in detecting and monitoring hypothyroidism. Materials and Methods . A case-control design of the study included 90 participants between the ages of 20 and 50 years. These participants were divided into three groups: overt hypothyroidism (OH), subclinical hypothyroidism (SCH), and a control group of healthy individuals. Anthropometric data, including age, sex, weight, height, body mass index (BMI), and hormonal parameters were measured and recorded for each participant. Results. Our work demonstrates that serum PTX3 levels were significantly elevated in individuals with hypothyroidism, compared to those with normal thyroid function (p<0.001). Furthermore, PTX3 levels correlated positively with TSH levels (r=0.62, p<0.001) and negatively with T4 levels (r= -0.53, p<0.001). Conclusion. The findings suggest that serum PTX3 levels can be a useful biomarker for detecting and monitoring hypothyroidism, particularly in cases of SCH. The study’s exclusion criteria made sure that no other systemic illnesses or medication use could have tainted the findings. Therefore, the use of plasma PTX3 levels in hypothyroidism detection and monitoring may prove to be a valuable clinical tool in the future.

Abstract There is a connection between bioavailability and absorption. In the field of pharmacology, this is referred to as a category of absorption and is defined as the proportion of a particular dosage of a drug that does not change and is absorbed into the systemic circulation. Both the overall absorption of medications and their specific bioavailability are important factors to consider in treatment. In this paper, we will go into great detail about the bioavailability of phytochemicals. We will also discuss the factors that influence bioavailability, the processes that improve bioavailability, and the phytochemicals that act as important bio enhancers, which are agents that improve the bioavailability of drugs.

Abstract Many clinical contexts require radiological exams based on contrast media administration. Iodinated contrast media (ICM) represents one of the most studied contrast agents often used in radiological examinations. ICM vary widely in their physicochemical properties, clinical uses, as well as in the incidence of adverse reactions (ARs). Therefore, a basic understanding of ARs occurrence, risk factors, clinical features, and management of ICM is increasingly important in clinical practice. Iopromide is a nonionic ICM widely used in clinical practice due to its favourable safety profile and numerous applications. This narrative review provides a comprehensive report of the available data concerning iopromide ARs. It also analyses iopromide ARs occurrence and frequency with diverse potential risk factors such as age, sex and pre-existing conditions.

Abstract Genetic variations in the receptor, metabolizing enzymes and transporters may explain a part of the variation in anti-emetic response to ondansetron among cancer patients. This study assesses the role of ABCB1 genetic polymorphisms in the anti-emetic efficacy of ondansetron-based medication for cisplatin-based chemotherapy in South Indian cancer patients. The frequencies of common ABCB1 polymorphisms (rs1045642; C > T , rs1128503; C > T and rs2032582; G > T / A ) were studied in 234 South Indian cancer patients receiving cisplatin-based chemotherapy. Comparison of nausea and vomiting with respect to number of episodes and severity by Visual Analogue Scale (VAS), and Common Terminology Criteria for Adverse Events version 4.0 (CTCAEv4.0) was made across genotype groups of each polymorphism. TT genotype carriers of all three polymorphisms had significantly lesser incidence of nausea and vomiting when compared to other genotypes of the respective polymorphisms during 2-24 hours and on days 2-5. Median VAS score for nausea and vomiting was also lower for TT genotype carriers at each time point except for nausea on days 2-5 (p=0.057) of C 3435T . As per CTCAEv4.0, TT genotype carriers had less severe grade at each time point except for days 2-5 nausea (p=0.278) and vomiting (p=0.219) of C3435T and nausea on days 2-5 (p=0.068) of G2677T/A: TT genotype of ABCB1 genetic polymorphisms was associated with anti-emetic response to ondansetron-based medication in the population studied. Hence, genotyping for ABCB1 polymorphisms may be used as a tool to predict response to ondansetron.

Abstract The study’s goal is to appraise the immunological inflammatory marker Trefoil Factor 3, which interacts with thalassemia pathogenesis particularly following splenectomy, and may offer new therapy options for the illness and its repercussions. This is a case-control study design that included 60 patients identified as β-thalassemia major as participators in this study, in addition to 30 seemingly healthy subjects with age and sex close to the patients group who served as a control group. The participants were distributed into four groups: control group, splenectomized patients, non-splenectomized patients, and total patients. Suitable statistical techniques were employed to investigate the results. The study’s findings demonstrated that there was a significance increase in the serum levels of TFF3 when comparing between (splenectomized, non-splenectomized and total patients) with healthy group (322.16±51.241, p-value=0.01, 317.20±42.449, p-value=0.01, 320±46.6, p-value=0.01), vs (309.38±21.94), respectively. Moreover, a comparison between splenectomized and non-splenectomized showed a significantly decrease in TFF3 (322.16±51.241) vs (317.20±42.449), (p-value=0.043).The presented study also revealed significant positive correlation between TFF3 level with ferritin, iron, total iron binding capacity, transferrin saturation, transferrin, fasting serum glucose, insulin and homeostasis model assessment-insulin resistance. Furthermore, unsaturated iron binding capacity and homeostasis model assessment-beta found a significant negative correlation with TFF3 level. High serum levels of TFF3 in beta thalassemia patients, especially in splenectomies patients, are downregulated by inflammatory cytokines, which are primarily regarded as traditional inflammatory cytokines and are related to insulin resistance. Hence, TFF3 level can serve as a potential predictive for the early detection of beta thalassemia in the development and progression of complications.

Abstract Essential oils (EOs), being mixtures of various natural compounds, constitute an attractive source of novel antimicrobial agents. Along with multiple studies concerning their rich biological activity, there are different methods allowing to determine both antimicrobial activity in direct contact, as well as through the activity of vapours. Thyme constitutes one of the most common aromatic herbs used for pharmaceutical, cosmetic and culinary purposes. The aim of the study was to compare the antibacterial activity of liquid and vapour phases of Thymus vulgaris L. essential oil (TEO) against most common pathogenic Gram-positive ( Staphylococcus aureus ATCC 25913, Enterococcus faecalis ATCC 29212, Bacillus cereus ATCC 10876) and Gram-negative ( Escherichia coli ATCC 25922, Salmonella typhimurium ATCC 14028, Pseudomonas aeruginosa ATCC 27853) microorganisms. To determine TEO antibacterial properties, two methods were used: disc-diffusion assay so as to test activity in direct contact; disc-volatilization assay so as to determine activity in gaseous contact. Statistical analysis showed that Gram-positive bacteria were more sensitive to TEO vapours than Gram-negative (p=0.005), while in the case of disc-diffusion assay, no such differences were evident. Moreover, sensitivity towards TEO differed among Gram-positive bacteria in disc-diffusion (p=0.009) and disc-volatilization assay (p=0.001). Among Gram-negative rods, a statistically higher sensitivity regarding E. coli was noted when compared to S. typhimurium in both direct (p=0.011) and gaseous (p=0.006) TEO contact. No activity of TEO against P. aeruginosa was found. As thyme essential oil exhibited significant antimicrobial activity against Gram-positive bacteria in gaseous contact, this justifies its use as an addition to inhalation agents to prevent or support the treatment of upper respiratory tract infections. Further studies should therefore apply other methods for determining the antibacterial activity of TEO vapours to assess the exact minimal concentration inhibiting bacterial growth.

Abstract Pathological evaluation of colorectal cancer resection samples play a vital role in management and prognosis of postoperative cancer patients. Difficulties exist in the assessment and outcomes of these specimens for therapy protocol. PNI is a perineural invasion associated with increased mortality in many malignancies including colon cancer. In colorectal cancer (CRC) and nearby tissue, PNI evaluation as a potential prognostic indicator with the use of CD 166 stem cell marker remains to be clearly defined for providing a convenient information for future management and prognosis. The incidence and significance of histological neural invasion in nearby tissue was conducted in 52 patients with colorectal carcinoma operated on for the period from June 2017 to June 2020 retrospectively. Tumors were subjected to histopathological and immunohistochemical study (IHC) with CD166 stem cell marker for PNI in tissue adjacent to CRC. Data collected and analyzed, histopathological pictures was obtained and studied. Outcomes showed that neural invasion was expressed by Cd166 stem cell marker as strong and severe in patients with stage B and C in tissues nearby tumor which reveals bad prognostic features. Conclusions : Neurogenesis appeared to have a critical role in colorectal cancer progression. furthermore, current results indicated that neurogenesis functions as an independent predictor of outcomes for therapy protocol.

Abstract Introduction. The use of medicines involves trade-offs between their therapeutic benefits and inherent risks. Several studies show that numerous adverse drug reactions (ADRs) could be avoided by increasing patients’ awareness of medicine’s risks. Even though drug labels enclose relevant information about risks and benefits, this information often requires patient education and overall health literacy to improve medication adherence, thereby preventing ADR frequency. Aim. To describe patient awareness of ADR risks and the Portuguese Pharmacovigilance System. Methods. A questionnaire comprising 27 questions was conducted at a health centre in Coimbra, Portugal. This study included ninety-one patients. Risk perception was scored as positive (≥2.5 points) or negative (<2.5 points). Results were analysed by SPSS v 27.0. Results. This work highlights poor patient perceptions of risk with a rate of negative responses of 85,7%. Although some responders were aware of the possibility of reporting ADRs, only some participants were familiar with the Portuguese Pharmacovigilance System. Additionally, only five patients – out of the vast majority of those who had previously encountered ADRs – reported the event to INFARMED. Conclusion. Patient low literacy regarding ADRs and the national reporting systems need to be urgently improved. Patient-centred communication strategies for recognising regulatory requirements and standards of product safety are important measures to achieve effective awareness through routine reporting within the Pharmacovigilance systems.
摘要介绍。药物的使用涉及其治疗益处和固有风险之间的权衡。一些研究表明，通过提高患者对药物风险的认识，可以避免许多药物不良反应(adr)。尽管药品标签上附有有关风险和益处的相关信息，但这些信息通常需要对患者进行教育和全面的健康素养，以提高服药依从性，从而防止不良反应的发生。的目标。描述患者对不良反应风险的认识和葡萄牙药物警戒系统。方法。在葡萄牙科英布拉的一个保健中心进行了一份包含27个问题的调查表。这项研究包括91名患者。风险感知分为正面(≥2.5分)和负面(<2.5分)。结果用SPSS v 27.0进行分析。结果。这项工作突出了不良的风险患者的认知率为85,7%的负面反应。虽然一些应答者意识到报告不良反应的可能性，但只有一些参与者熟悉葡萄牙药物警戒系统。此外，只有5名患者(在绝大多数以前遇到过adr的患者中)向INFARMED报告了这一事件。结论。患者对不良反应的低识字率和国家报告系统亟待改善。以患者为中心的沟通策略，以识别法规要求和产品安全标准，是通过药物警戒系统内的常规报告实现有效认识的重要措施。
