- L-cysteine sequestering methyl glyoxal prevents protein glycation: a
combined and evaluation
Abstract: Reactive carbonyl species such as methylglyoxal (MGO) act as potent glycating agents that are implicated in several oxidative stress-induced diseases, including, but not limited to, cancer, diabetes and neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases. In the present study, a combined approach of initial computational studies and in vitro analysis was utilized to investigate the therapeutic benefit of L-cysteine (CYS), a thiol-containing compound. Based on the reactive analysis using global and local density functional theory (DFT) descriptors, the data reported here has revealed that CYS matches its electron-donating capacity with the electron acceptor, methylglyoxal, making the former a good candidate sequestering agent for the latter. Furthermore, in vitro analysis shows that CYS exhibits significant inhibitory effects towards damaging protein structural alteration and formation of advanced glycation end products (AGEs). Such assessment came about through Congo red binding Assay and Antiglycation Assay using BSA-MGO and BSA-glucose model systems. Additionally, CYS also demonstrates a significant protective effect towards MGO-induced oxidative stress in mouse C2C12 myotubes. Therefore, this thiol-containing compound is a promising therapeutic tool for several glycation or AGEs-induced pathological conditions. The use of more relevant cellular and animal models of desired disease studies is recommended to better understand the mechanistic basis of CYS’s potential therapeutic effect. This study utilizing the combined approach of computational and in-vitro analysis, provides helpful data to maximize the potential impact of CYS by designing related molecules that could serve as novel treatment strategies that are effective, safe, and accessible to all in the future.

- Effect of heat treatment on the secondary metabolites composition of L.
rhizome
Abstract: Turmeric (Curcuma longa L.) is a widely known plant that is commonly used as a spice. It is also a valuable raw material that is increasingly used in the pharmaceutical industry and, notably, in dietary supplement recipes. For a long time, the healing properties of turmeric have been used in folk medicine in many regions of the world, mainly to treat various types of diseases. When developing recipes and preparing preparations with medicinal properties, the turmeric rhizome is subjected to various types of thermal treatment. These processes cause qualitative and quantitative changes in the composition of the secondary metabolites present in the turmeric rhizome. Due to its great popularity and widespread use as a raw material with health-promoting properties, turmeric undeniably deserves an in-depth analysis in order to optimize the treatment process and minimize its negative impact on active compounds. The presented review summarizes the current state of knowledge on the impact of thermal treatment of the turmeric rhizome on the composition of its biologically active compounds. The data provided in this review indicate that the content of active compounds in turmeric rhizomes is strictly correlated not only with the used type of processing, but it also strongly depends on the selection of key parameters. Therefore, it is difficult to clearly indicate the type of processing that would be the most beneficial for the composition of its active compounds.

- Anti-tumor and anti-oxidant effects of extracts on oral squamous cell
carcinoma and skin squamous cell carcinoma
Abstract: Ganoderma lucidum has had great importance in healthcare in the Chinese for many decades. Polysaccharides and triterpenoids are one of the most important components of G. lucidum. Biological evidence indicates that this mushroom can be a promising treatment in many cancer cases and reduce the toxic effect of chemotherapy and radiotherapy if taken synchronously. This study highlights preparing an extract with therapeutic effects capable of removing free radicals and protecting cell membranes from hyperoxidation effects. The antitumor effect was evaluated on two types of cancer cell lines in vitro, Human Oral Squamous Cell Carcinoma (HOSCC) and Human Skin Squamous Cell Carcinoma (HSSCC), at different concentrations 0.0-1600 µg/mL. Antioxidant by DPPH assay was assessed at concentrations from 0.0-500 µg/mL, in addition to their effects on cytogenetic indicators such as mitotic index (MI), blastogenic index (BI) and total chromosomal aberration (TCAs) for three types of extracts (ethanol extract, water extract and acidified water extract). The results recorded an increase in the antioxidant activity of the three extracts, and that the acidified water extract had the highest effect, reaching a killing rate of 78.53% for the acidified water extract on the HOSCC cell line. Chromosomal stability indicates that the three extracts enhanced the cytogenetics parameters and supported chromosomal stability by increasing both mitotic index (MI) and blastogenic index (BI), while reducing chromosomal aberrations.

- Formulation and development of Tacrolimus nanosponges-loaded hydrogel for
the treatment of atopic dermatitis
Abstract: Targeted drug delivery to specific locations is a significant challenge encountered by researchers. Nanosponges have emerged as a promising solution for delivering drugs to their target sites. Nanosponges are nanoparticles with a large surface area, allowing for enhanced penetration compared to conventional drug delivery systems. This new technology offers controlled drug release and has several advantages over other methods. This project aimed to prepare and evaluate a Tacrolimus-loaded Nanosponges hydrogel. The goal was to create a dermatological gel suitable for local drug delivery after topical application, aiming for improved therapeutic effects, better dispersibility and good storage stability. Tacrolimus-loaded Nanosponge was prepared using beta-cyclodextrin and ethylcellulose as polymers, along with polyvinyl alcohol (PVA) as a surfactant. The solvent emulsion diffusion technique is a method for preparing nanosponges, and the variations in the formulation using different polymers and drug-polymer ratios offer the opportunity to fine-tune the nanosponge’s properties to meet specific requirements for drug delivery applications. A Tacrolimus-loaded nanosponge hydrogel was formulated using carbopol 934. The results of the study indicated that the optimized batch of nanosponges with high entrapment efficiency was chosen for formulating the gel incorporating carbopol 934. The gel that was prepared was subjected to assessments for pH, viscosity, spreadability, in-vitro diffusion, permeation and stability. The findings suggest that Tacrolimus can be effectively formulated in low doses of nanosponges-loaded hydrogel for atopic dermatitis.

- A diagnostic challenge – autoimmune encephalitis as paraneoplastic
syndrome of ovarian teratoma. Current state of knowledge
Abstract: Autoimmune encephalitis (AE) is one of the paraneoplastic syndromes of ovarian teratoma. Insufficient knowledge about the evolution of the disease, as well as its manifestation in the form of non-specific clinical symptoms (such as significant deterioration of memory and cognitive functions of patients), is a common cause of a prolonged diagnostic process and delay in the introduction of targeted treatment. The aim of the study was to summarize the data available in the literature, as well as recent reports, to facilitate and accelerate the diagnosis of the syndrome and ensure better care for patients.A literature review was performed in the PubMed, Google Scholar databases and the guidelines of the Polish Society of Gynecologists and Obstetricians, by using keywords. Making a diagnosis of AE requires the cooperation of a team of specialists (including, among others, neurologists, gynecologists and oncologists). Justification for this is the manifestation of pathology comes in the form of non-specific clinical symptoms. Treatment includes surgery to remove the tumor, pharmacotherapy: corticosteroids and immunoglobulin infusions, in addition to allied modern plasmapheresis treatments – in severe cases.Sorting out the non-specific symptoms of AE would facilitate faster and more accurate diagnosis, and this improve the functioning of patients suffering from ovarian teratoma. Pertinent tests are necessary to facilitate and optimize the differential diagnosis. Education of doctors about its alarming symptoms is important, as is cooperation between doctors of different specialties.

- Vitamin D25-OH concentration in outpatient and hospitalized geriatric
patients – retrospective study
Abstract: A majority of the Polish population was found to have vitamin D deficiency. The problem was expected to grow in the elderly during the COVID-19 pandemic related lock down. The aim of the study was to compare concentrations of vitamin D in the blood sera of geriatric patients treated in outpatient clinics or hospitalized – and in the methods of treatment used. A retrospective study of the records of patients of the Rheumatology Outpatient Clinic and the Geriatrics Ward in Lublin was conducted.In 2022, 80 people: 50 hospitalized women (HW) and 30 hospitalized men (HM) were admitted to the Geriatrics Ward in Lublin. Of these, 78 persons had vitamin D levels measured. From the Rheumatology Outpatient Clinic, medical histories of 68 outpatient women (OW) and 27 outpatient men (OM) 60+ were analyzed. In HW and HM, mean vitamin D concentration was 23 ng/ml and in OW and OM 25 ng/ml. The OW and OM with vitamin D concentration <30 received prescription for cholecacliferol 20 000 IU to be administered orally twice a week. The follow-up visit 2 was months later. Out of 47 OW, 17 came for the follow up and their results improved. Out of 21 OM, 100% returned, but their results were less satisfactory. The HW and HM received cholecalciferol 2000 IU. There was no follow-up.In total, 41% of the outpatient elderly and 55% of the hospitalized had vitamin D concentration <20 ng/ml. Treatment of vitamin D deficiency with 20,000 IU cholecalciferol twice a week for two months is effective.

- A multivariate generalized linear model of the effect of matrix
metalloproteinase-3 and tissue inhibitor of metalloproteinase-1 in
end-stage renal disease
Abstract: End-stage renal disease (ESRD) is a serious disease that requires hemodialysis as the main regimen for supporting patients. The pathophysiology of the disease is still an interesting field of study. In the present study, matrix metalloproteinase-3 (MMP3), a tissue inhibitor of metalloproteinase-1 (TIMP1), and vitamin D (VitD) were studied in ESRD. MMP3, TIMP1, VitD, and other related biomarkers were measured in 53 ESRD patients and compared with 33 healthy controls. The results showed a significant increase in serum MMP3 and TIMP1 and a significant decrease in serum VitD in ESRD patients compared with the control group. The multivariate GLM results revealed no significant effects of the covariates (sex, age, smoking and BMI) on the levels of MMP3, TIMP1 and VitD. ESRD was found to be the major factor affecting the measured parameters, with a huge effect size (Partial η2) of 0.824. According to our data, eGFR, Creatinine, Urea, phosphate, uric acid and VitD (as estimated glomerular filtration rate) are the top 6 factors highly affected by the presence of the disease. MMP3 and TIMP1 are important parameters in ESRD and may act as drug targets. As the patients also suffered from hypovitaminosis D and hypocalcemia, these factors also need intervention.

- The Multiple-Locus Variable Number Tandem Repeat Analysis (MLVA) of
clinical isolates recovered from the Provincial Specialist Hospital in
Lublin, Poland
Abstract: Understanding the epidemiology and evolution of Staphylococcus aureus (SA) is crucial for implementing effective infection prevention and control measures. In this study, a short-term (4-month) and local molecular epidemiology of SA in the nosocomial setting was investigated using multiple-locus variable number tandem repeat (VNTR) analysis (MLVA). The study included 31 clinical SA isolates. The analysis was based on two complimentary panels encompassing 14 VNTR loci wherein a first-line assay comprised a subset of 10 loci (Panel 1), followed by a second subset of four loci (Panel 2). Thirty MLVA profiles were generated. Small amplicons were obtained for three out of the four loci included in Panel 2 for more than half of the isolates, making the calculation of the number of repeats impossible. Therefore, phylogenetic clustering was based on the analysis of basic loci included in Panel 1 (which identified two major genetic clusters). Cluster I included 26 (84%) isolates, among which 14 were classified into five sub-clusters (cutoff value ≥65%). Only one pair of the isolates shared an identical MLVA pattern. Our study indicates the usefulness of a MLVA tool comprised of a primary subset of 10 loci to track the possibility of SA intra-hospital transmission. We report a high genetic diversity of the isolates and suggest a limited degree of intra- and inter-ward SA transmission. Further genetic studies are necessary to investigate the nature of the small alleles yielded in Panel, as their subset can provide even higher resolution of the assay.

- Knowledge of the sign prohibiting alcohol consumption during pregnancy
among medical students in Poland – a survey study
Abstract: Signs, including pictograms, present in public space are intended to enforce a specific behavior. Due to their simplicity and unambiguity of the message, they can be an effective tool of public healthcare. The aim of this study was to assess the knowledge referred to the meaning of the sign prohibiting alcohol consumption during pregnancy among first-year medical students who do not have vast knowledge at present level in this field. The study was conducted among academic youth in Poland, and assumed a 5% risk of error, hence, for p <0.05 the differences were considered statistically significant. Out of the total number, there were 1,123 questionnaire forms correctly completed and these were further selected for the final analysis, which comprised of 751 by women and 372 by men. Among the respondents, over 92% properly recognized the sign warning against the use of alcohol during pregnancy. Moreover, more than 45% declared previous contact with this sign and above 53% claimed that they already had knowledge of the sing’s meaning. The graphic form of the sign allows for its correct interpretation, thus products which may become harmful especially to pregnant women and fetus can be clearly and legibly marked.

- Detection of Epstein-Barr virus among chronic kidney disease patients in
Najaf, Iraq
Abstract: Many people across the world have been infected with Epstein Barr virus (EBV), a kind of a human herpes virus. Loss of kidney function happens progressively with time in those with chronic kidney disease (CKD). Individuals with CKD may be more susceptible to viral infections such as EBV due to their compromised immune systems. The purpose of this research is to quantify the frequency with which EBV infection occurs in patients with CKD in the Al-Najaf governorate. Blood samples from 50 people with CKD and 50 healthy controls were collected for the study at the Specialized Centre for Diseases and Kidney Transplant at Al-Sadder Medical City in Al-Najaf city. Nineteen of the CKD patients were men, whereas 31 were women. The age range of individuals who took part in the research varied from 17 to 47. The time frame for this study’s data gathering was from January 2022 to December 2022. Fifty hemodialysis patients gave blood samples for analysis. Researchers measured anti-EBV IgG antibodies using the ELISA method to evaluate the efficacy of humoral immunity. Eleven (22% of all samples) were found to have positive results for Epstein Barr nuclear antigen2 (EBNA2) IgG. This number was 43.1% of all males and 38.4% of all females. However, the serum concentration was found to be statistically significantly higher in the age range of 17-26 years (p0.05) than in any other age group. The RT-qPCR method was also applied to detect EBV infection in the study. Only 18 (36% of the sample) of the 50 patients had positive RT-qPCR results for EBV. This number was 15.7% of all males and 48.4% of all females; however, the positivity rate increased to 71.4% in the (17-26) age group and decreased to 28.5% in those older than 57. Results from the control group were negative for EBNA2 IgG antibodies and EBV DNA. Findings of this research demonstrate that the prevalence of EBV antibodies is considerably higher among patients undergoing hemodialysis than in the group serving as a control, regardless of age. In addition, the results of the study support the use of real-time PCR for detecting EBV among patients with CKD, due to its high sensitivity and specificity.

- Methylenetetrahydrofolate reductase levels and gene expression in leukemia
Abstract: Leukemia is a neoplastic disease that affects the proliferation of white blood cells and their progenitors. Folic acid deficiency is well-known as a risk factor for leukemia. Methylenetetrahydrofolate reductase (MTHFR) enzyme functions in the folate metabolism route, DNA synthesis and methylation processes. Numerous research has been conducted to investigate the link between MTHFR and several human illnesses, including cancer, cardiovascular disease, psychiatric disorders and neurological issues. The current study aimed to examine MTHFR levels and gene expression in patients with leukemia. The research was carried out between February and October of 2022. There were 130 subjects in total, 80 with leukemia, 45 with AML (Female = 16, Male = 26) with a mean age of (32.32±2.69), and 35 with ALL (Female = 16, Male = 19) with a mean age of (35.794±0.63). The study included 50 healthy subjects as a healthy control group (Female = 28, Male = 22), with an average age of (41.8±1.57) years. MTHFR and Folic acid were measured using ELISA, while MTHFR mRNA was assessed using qPCR in blood and plasma. Folic acid and MTHFR levels were found to be lower in patients with AML and ALL compared to controls (p <0.01). MTHFR gene expression was found to be downregulated in leukemia patients (p <0.01).The findings of the study give support for future research into the effect of folic acid level and supplementation on leukemia-associated pathological outcomes. Folic acid deficiency may affect the folate mediate-one carbon metabolism pathway, as evidenced by changes in the expression of the mRNA MTHFR gene. As a result, more research into the effects of folate status and folic acid supplementation on leukemia is needed to investigate potential therapeutic strategies.

- Quantification of chlorogenic acid in L. stem ethanolic extracts and its
antioxidant activity
Abstract: Chlorogenic acid (CA) is an important phenolic acid antioxidant. It is found in Pluchea indica L. (Asteraceae). However, it has only been extensively studied in the leaves, while studies on the stems have not been reported. This study aimed to identify and measure the levels of CA in the stem extract of P. indica. The extract was also determined for its antioxidant activities. In the course of the work, P. indica stems powder was extracted using the ultrasonic-assisted extraction (UAE) technique employing 50%-ethanol as solvent directly and sequentially. The extract was then measured for total phenolic content (TPC) and CA content using RP-HPLC. Meanwhile, antioxidant activities were determined by the DPPH, ABTS, and reducing power (RP) methods. TPC in the sequential and the direct of P. indica stems ethanol extracts were 1.4694±0.0228 and 1.9314±0.0318 mgGAE/g DW, respectively. We found that the CA content of 50%-ethanol extract of P. indica stems from sequential extraction (0.2045±0.0128%, w/w) was higher than 50%-ethanol extract from direct extraction (0.1984±0.0113%, w/w). The two extracts demonstrated good antioxidant capacity, while the ethyl acetate and n-hexane extracts did not. Identifying of other antioxidants phenolics using other extracting methods still needs further study.

- Main consequences of enzymatic induction and inhibition during the
interaction of drugs and the role of CYP3A4, CYP3A45 enzymes
Abstract: The microsomal enzyme system is responsible for the metabolism of pollutants, toxic agents and drugs. With regards to drug metabolism, the activity of the constituent microsomal enzymes results in the reduction of pharmacological and toxicological activity through conversion of hydrophilic (water soluble) compounds to allow urinary excretion. Microsomal enzymes oxidize drugs and steroid hormones in reactions that require adenine nucleotide diphosphate (NADPH). Reversible inhibition reduces enzyme activity through reversible interaction. A covalent bond between the inhibitor and the enzyme can promote the destruction of essential functional groups of the enzyme. Enzyme induction and inhibition are problematic in drug polytherapy. Often the lack of effect of a drug or the side effects that a certain drug exhibits are problems of interaction of drugs with each other in that individually they inhibit or stimulate enzyme activity.

- Comparative evaluation of anti-anemic effect of Sucrosomial iron in
experimental model of iron deficiency anemia in Wistar rats
Abstract: Anemia is a grave public health issue that affects 25% of the global population. Conventional iron formulations used in treatment have drawbacks such as poor bioavailability and gastric intolerability. The current study aimed to evaluate the anti-anemic effects of different iron salts in Wistar rats with iron deficiency anemia (IDA). IDA was induced by the validated pre-clinical model by retro-orbital bloodletting (1 ml) for 21 days along with an iron-deficient diet in Wistar rats. The rats (n=48) were assigned into 8 groups: Control group, IDA rats, IDA rats receiving either vehicle or different iron salts (ferrous sulfate, ferrous ascorbate, ferrous fumarate, and Sucrosomial iron) for 21 days at a dose of 30 mg/kg p.o. Hematological parameters and iron store indices were assessed at each visit.Anemia induction markedly reduced hemoglobin levels in all IDA groups on day 21. In contrast, iron supplements showed significant improvement in hematological profile after 21 days of treatment. Interestingly, the Sucrosomial iron-supplemented group (group 8) showed significantly higher improvement in hemoglobin levels and hematocrit than did conventional iron supplements such as ferrous sulfate (group 5), ferrous ascorbate (group 6) and ferrous fumarate (group 7) (p <0.05 for each group, respectively). Sucrosomial iron also showed slightly better improvement in iron store indices (serum iron & ferritin levels, total iron binding capacity and transferrin saturation [%]) when compared with other iron supplements (non-significant difference).
Authors concluded that Sucrosomial iron has a significant potential to improve IDA in Wistar rats compared to conventional iron salts. Sucrosomial iron can be useful for the management of IDA either prophylactically or therapeutically.

- Synergistic effects of omega-3 polyunsaturated fatty acids and aspirin in
the clinical practice – a narrative review
Abstract: The review aimed to illustrate the structure, role and effects of omega-3 polyunsaturated fatty acids (omega-3 PUFAs) in combination with acetylsalicylic acid (aspirin, ASA) in various clinical cases. This verification of earlier single studies may be a guide in the further treatment of civilization diseases. The results of the presented narrative review suggest that aspirin supplementation with omega-3 fatty acids reduces pro-inflammatory biomarkers in sepsis and acute respiratory distress syndrome. Including adequate amounts of omega 3-PUFAs in therapy, rather than increasing the dose of acetylsalicylic acid, may contribute to beneficial effects in treating thrombosis and preventing myocardial infarction or other cardiovascular diseases, which is particularly important in aspirin-resistant patients. As suggested in the literature, a low daily dose of omega-3 fatty acids was effective in slowing the progression of kidney disease with IgA nephropathy. Aspirin supplementation with omega-3 fatty acids has improved clinical and immunological outcomes in the treatment of periodontitis or the therapy of colorectal cancer tumor lesions. The synergistic effect of both compounds is proposed as a new therapeutic option in the treatment of Parkinson’s disease. Further research into the synergistic effects of omega-3 fatty acids in combination with acetylsalicylic acid may provide a breakthrough in drug dose reduction, ultimately enabling more effective and safer pharmacotherapy for the patient. Therefore, studies on polyunsaturated fatty acids in combination with nonsteroidal anti-inflammatory drugs in vivo are needed.

- A comparison of the potential of Clinical Trials Centers within both
public and commercial trial facilities
Abstract: Clinical trials are an integral part of the process of developing new drugs, diagnostic methods and medical devices. Clinical trials offer patients the chance to access alternative treatment methods, thereby improving their quality of life, and even achieving recovery. Additionally, clinical trials provide the opportunity for regular contact with a specialist doctor and easier access to diagnostics, ensuring a faster therapeutic path for the patient. One of the key aspects of conducting clinical trials is choosing the right investigator and research center so as to meet specific criteria and guarantee high quality of the conducted studies. Therefore, the aim of the current study was to evaluate the differences between conducting clinical trials in public and commercial centers. A diagnostic survey was used in the study and the research tool chosen was a proprietary questionnaire belonging to the research technique as survey questionnaire. Questionnaires were constructed for the appropriate stakeholders/respondents, namely: doctors and employees of pharmaceutical companies and CROs. The analysis showed that employees of pharmaceutical companies, given the choice, prefer to cooperate with commercial centers. They choose public centers only when they need a center for phase one trials or those requiring hospitalization. The research obtained shows that public centers should improve administrative processes in order to optimize tasks such as contracting or obtaining a study.

- Impact of dietary and herbal supplements on global health of adult
volunteers
Abstract: The safety and efficacy of multivitamin-multimineral-multiherbal (MVMH) supplementation is in regular debate but should be studied in detail before recommendation. The purpose of the study was to evaluate whether MVMH supplementation affects the physical and mental performance of individuals taking these, as well as to ascertain its safety, doing so through blood, kidney and liver profiles.In this Cross over cohort study, we enrolled 30 healthy volunteers and established their anthropometric, stress, anxiety and depression levels before and after 30 days of the study. Their kidney function test, liver function test and blood profile results were also analysed to determine overall health effects of the supplement and assess its safety. Parametric data was examined via Paired T test, followed by One Way ANOVA, Non-parametric data is presented as percentage and analysed by applying Paired Sample Wilcoxon Signal Rank Test followed by Friedman ANOVA test.All the volunteers were in good health, had no change in medical state. No serious adverse event was reported during the study and after the completion of study. Treatment with MVMH tablets had shown very significant (p <0.01) increase in the level of globulin, uric acid (p <0.05), hemoglobin, and hematocrit levels (p <0.05), BMI and body weight (p <0.05). There was significant (p <0.05) improvement in symptoms of anxiety, depression and stress.The daily intake of MVMH supplements in the form of a tablet once per day improved global health of individuals, along with improvement in mental performance without any significant adverse impact on the body. Based on the results, we recommend that MVMH tablets may be taken once per day for 30 days to improve the physical and mental health of individuals.

- Changes in pharmaceutical prescription authorizations and their impact on
the number of prescriptions issued by pharmacists in Poland
Abstract: The Pharmaceutical Law Act of September 6, 2001 (PLA) initially granted pharmacists the authority to issue pharmaceutical prescriptions upon its enactment. However, the legislation regulating this matter changed significantly in 2015. Article 96, section 4 of the PLA defined that, in the front of a direct health threat to a patient, a pharmacist could dispense a medication classified under the availability categories Rp or Rpz. In April 2020, the imprecise term “sudden” in relation to health threats was clarified and removed. Concurrently, all active pharmacists were granted the authority to issue prescriptions, commonly known as pro auctore and pro familiae. The aim of the study was to illustrate the influence of legislative processes on the number of prescriptions issued by practicing pharmacists. To conduct the study, we employed a legal and comparative analysis of relevant legal provisions, followed by a statistical analysis of data obtained from the E-Health Center about the number of prescriptions issued. The results indicated that since the extension of pharmacists’ rights (after April 2020), the average number of pharmaceutical prescriptions issued per month was 151,082. Between May 2020, when pharmacists were granted the authority to issue pro auctore and pro familiae prescriptions, and October 2023, 1,460,385 such prescriptions were dispensed. As a result, a significant relationship between the form of the legislative norms empowering pharmacists to independently prescribe Rx status medicines and the effectiveness of these amendments as measured by the number of prescriptions issued was demonstrated.

- Selected miRNAs in oropharyngeal squamous cell carcinoma (OPSCC) with HPV
and EBV coinfection
Abstract: Different levels of miR-625-5p, miR-31-5p and miR-5100 have been reported in many cancers. Viral infections have been linked to miRNA levels in tumors, including those in the head and neck, but a large proportion of studies only include infections with a single virus. The aim of the present study is to assess the level of miR-625-5p, 31-5p and 5100 in oropharyngeal cancer with single HPV and EBV infections and HPV/EBV co-infection. The study examined 128 oropharyngeal cancer patients infected with EBV and HPV alone or co-infected with both viruses. For the determination of miRNAs, the enzyme immunoassays was used. Both miR-625-5p and miR-31-5p were higher in the HPV/EBV co-infection than in the single infection HPV or EBV. However, in the case of miR-5100, the values in co-infection were lower than in a single EBV infection. The analysis of miRNAs in relation to the histological grade and tumor classification, nodes (TN) showed that in poorly differentiated tumors the level of the studied miRNAs was higher compared to well-differentiated lesions, and in cases with larger tumor sizes and lymph node involvement, the miRNA values were both higher in single infections and co-infections.
