(Publishing Office of the University of Rzeszow, 2024-06) Vashisht, Ketan; Sethi, Pooja; Bansal, Anshul; Singh, Tejveer; Kumar, Raman; Tuli, Hardeep Singh; Saini, Shallu
Introduction and aim. The synthesis of heterocyclic compounds containing oxygen and nitrogen is profoundly intriguing due to their mechanistic implications in both research and development within organic chemistry and drug discovery. The primary aim of this study is to fabricate a range of pharmacologically active drugs containing the isoxazole moiety. Material and methods. The synthesis of new derivatives of isoxazole was achieved through a one-pot condensation reaction of 2-[(Substituted phenyl)hydrazono]malononitrile (1) and 3-[(Substituted phenyl)azo]-2,4-Pentanedione (2) with sodium acetate and hydroxylamine hydrochloride (1:1) in ethanol. All the compounds were screened for their in vitro antibacterial activity, in vitro antioxidant and anticancer activity. The synthesized compounds underwent characterization through FTIR, 1 H NMR, and 13C NMR analyses, supported by mass spectral data and elemental analysis. Results. A set of novel isoxazole derivatives was synthesized with a favorable yield. Among compounds 1d, 1e, 2c, 2d, and 2e exhibited notable antioxidant activities. Compounds 1a, 1b, and 1c demonstrated significant anticancer potential against prostate cancer [PC3] cell lines compared to normal HEK cell lines, while 2a displayed the highest inhibitory zone against Escherichia coli. Conclusion. Novel compounds with multifaceted biological activities have been successfully designed, and a synthetic route to create isoxazole derivatives has been devised and verified.
Genetic factors contributing to the development of inguinal hernias – a narrative review
(Publishing Office of the University of Rzeszow, 2024-06) Kalali, Datis
Introduction and aim. Inguinal hernias are one of the major disorders in the field of general and visceral surgery and can be viewed as multifactorial diseases. Although the molecular mechanism that led to predistortion to inguinal herniation still remain unclear, is well known that defects leading to improper closure of the inguinal canal during fetal development and mechanisms contributing to weaker muscles of the abdominal wall can greatly increase the risk of developing the latter disease. Material and methods. A literature search was performed in all major electronic databases using keywords and Boolean operators to retrieve all available literature related to the topic. Due to the narrative nature of the review, there were no specific inclusion and exclusion criteria. Analysis of the literature. Genetic factors, undoubtedly, can interfere with these mechanisms and therefore play major role in developing hernias. To this end, the present narrative review provides an overview of genes with altered expression and genetic polymorphisms associated with inguinal herniation. Moreover, the results of genome-wide association studies (GWAS) exploring susceptible genetic loci associated with the disease have been reported. Conclusion. Nevertheless, more case-control studies and GWAS need to be conducted in different ethnic populations so as to provide better insights into the topic.

(Publishing Office of the University of Rzeszow, 2024-06) Lipińska, Justyna; Lipiński, Łukasz; Kopeć, Izabela; Kowalczuk, Maria; Woźniak, Magdalena Maria
Introduction and aim. Computed tomography (CT) is the first imaging modality in the evaluation of children in case of patients with head injury in pediatric Emergency Departments (EDs). Radiological CT reports include not only lesions that are the main cause of the child’s complaints but also incidental findings. The objective of this study is to assess incidental findings observed in children who were admitted to the ED and had the head CT performed. Material and methods. This retrospective, cross-sectional study enrolled 644 children under the age of 18, from 1st January 2021 to 31st June 2021. Each child could have had one or more incidental findings in CT Results. Among all CT studies, incidental findings were found in 279 out of 644 (43.32%) cases, of which 73 (11.34%) had both lesions detected incidentally and related to the trauma. Conclusion. Head CT is an incredibly useful tool in the assessment of some head emergencies. However, evaluation of the prevalence of incidental findings is difficult. Most of them require no specific further investigation. Pediatricians, who order CTs in children, must be prepared to interpret and communicate findings to families and introduce treatment in necessary situations.

(Publishing Office of the University of Rzeszow, 2024-06) Regeda, Mykhailo; Olekshij, Petro; Regeda-Furdychko, Maaryana; Furdychko, Lubomur; Kolishetska, Marta; Regeda, Stepan; Fil, Vitalii
Introduction and aim. The aim of this work is to study the parameters of the nitric oxide (NO) system in the blood of guinea pigs under the conditions of the experimental periodontitis (EP) and immobilization stress (IS) formation and to evaluate the effectiveness of thiocetam use. Material and methods. Experimental studies were performed on 50 guinea pigs (males, body weight 0.18–0.21 kg) which were divided into five groups (10 in each): the first group were intact animals as control; the second experimental group were animals with experimental periodontitis under conditions of immobilization stress (3rd day), the third group included guinea pigs with EP and IS on the 5th day of the combined model process, group IV – animals with EP and IS 15th day (without administration of thiocetam) and group V – animals on the 15th day of experiment with EP and IS after use of thiocetam. Results. As a result of this research, changes in the activity of the NO system in the blood were observed, namely an increase in the level of stable metabolites and an increase in the activity of total NO-synthase, which is accompanied by a compensatory inhibition of the L-arginine activity, and these indicators were most pronounced in the late stages of EP and IS formation. Conclusion. The use of thiocetam showed a corrective effect on the changed variables of NO metabolism in the peripheral blood of guinea pigs under the conditions of the EP and IS development.
Encapsulation of genistein in glycidylated G3 polyamidoamine dendrimers enables diffusion of genistein through biological membranes and anti-nematode activity of the encapsulate
(Publishing Office of the University of Rzeszow, 2024-06) Filipowicz-Rachwał, Aleksandra; Drozdowska, Joanna; Zagórska-Dziok, Martyna; Uram, Łukasz; Wołowiec, Stanisław
Introduction and aim. Poorly soluble isoflavonoid genistein is known as an anti-nematode agent and also it decreases the risk of certain types of cancer. The biological activity of genistein is limited mostly by its low solubility. Therefore many attempts to increase genistein solubility in water were reported. We applied a polyamidoamine dendrimer, modified its surface by glycidylation, and used this macromolecule as a guest for genistein. Material and methods. Polyamidoamine dendrimer 3rd generation was substituted with 64 glycidol residues to obtain a macromolecule host for genistein. The stoichiometry of this host-guest complex was determined. The complex was tested for skin model permeability, toxicity on fibroblast (BJ) and keratinocyte (HaCaT) cell lines in vitro and anthelmintic activity on the Caenorhabditis elegans nematode. Results. The partition coefficient of genistein between octanol and water was determined (KO/W). The 1:1 host-guest complex was isolated and used as drug delivery system for genistein delivery. PAMAM G3 glycidyled dendrimer containing genistein indicated an anthelmintic activity at 50 µM concentration. Conclusion. The solubility of genistein in water increases 640 times in presence of an equimolar concentration of the dendrimer. One molecule of host dendrimer encapsulates 3 molecules of genistein. The encapsulate is an efficient anti-nematode formulation.

(Publishing Office of the University of Rzeszow, 2024-06) Jawanpuria, Ankita; Behera, Aruna Rani; Dash, Chinmaya; Rahman, Mohammad Hifz Ur
Introduction and aim. An AI model like ChatGPT is a good source of knowledge. We can explore the potential of AI models to complement the expertise of healthcare professionals by providing real-time, evidence-based information in infection prevention and control (IPC). Material and methods. This study involved 110 queries related to IPC, validated by subject experts in IPC. The responses from ChatGPT were evaluated using Bloom’s taxonomy by experienced microbiologists. The scores were divided as 4 as a good response. Statistical analysis was done by correlation coefficient and Cohen’s Kappa. Results. The overall score was 4.33 (95% CI, q1 3.65–q3 4.64) indicating ChatGPT’s substantial IPC knowledge. A good response (i.e.>4 score) was found in 70 (63.6%) questions, while in 10 (9%) questions, it showed a poor response. The poor response was seen in needle stick injury and personal protective equipment (PPE) doffing-related questions. The overall correlations were found to be significant. Cohen’s Kappa confirmed moderate to substantial agreement between evaluators. Conclusion. ChatGPT demonstrated a commendable understanding of IPC principles in various domains and the study identifies specific instances where the model may require further refinement especially in critical scenarios such as needlestick injuries and PPE doffing.

(Publishing Office of the University of Rzeszow, 2024-06) Rada, Feryal
Introduction and aim. Oxidative stress is one of the complications that accompany defects in thyroid hormone levels. This study was designed to evaluate oxidative stress markers in patients with hypothyroidism. Material and methods. This case control study was comprised of forty-two hypothyroid patients aged 36–46 years and forty age matched (35–43 years) healthy control participants randomly selected from the Endocrine Clinic of Al-Yarmook Hospital in Iraq. Blood levels of thyroid hormones malondialdehyde, glutathione, and paraoxonase-1 were assessed. Body mass index was calculated for each patient and control participant. Results. Regarding the data of oxidative stress markers in hypothyroid patients compared to controls, a significant elevation was reported in blood levels of malondialdehyde and a significant reduction was found in blood levels of glutathione (p=0.031). On the other hand, the blood levels of paraoxonase-1 were significantly different in hypothyroid patients compared with the control. Conclusion. Elevated blood levels of malondialdehyde and declined blood levels of glutathione in hypothyroid patients are a signal of oxidative stress and consequently increase the risk of cardiovascular complications.

(Publishing Office of the University of Rzeszow, 2024-06) Apaydin, Mehmet; Dogan, Serap; Aypak, Cenk
Introduction and aim. Although increasing vaccination rates among healthcare workers (HCWs) is crucial for protecting their own health and preventing the spread of infections to patients, vaccination rates remain low. The purpose of this study is to evaluate the knowledge, attitudes, and behavior of healthcare workers concerning seasonal influenza vaccination in a training and research hospital in Türkiye. Material and methods. This cross-sectional descriptive study was conducted among 364 healthcare workers working in a training and research hospital in Ankara, Türkiye. A face-to-face questionnaire was completed by selected participants that included questions about their sociodemographic characteristics, receiving seasonal influenza vaccination, reasons for not receiving vaccination, attitudes and behavior towards seasonal influenza vaccination recommendations for their surroundings, knowledge of who should get the vaccine, and their immunization history. Results. Among the participants, 58.5% stated that they had never received an influenza vaccination, 35.7% mentioned not receiving the regular influenza vaccination, and only 5.8% reported receiving the influenza vaccination regularly every year. Reasons for not getting vaccinated included not trusting the influenza vaccine’s protection (60.1%), not believing they are in the risk group (38.9%), and not finding a suitable time to get vaccinated (36.1%). A total of 57.1% of the healthcare workers recommended the influenza vaccine for their surroundings. Conclusion. Influenza vaccination rates among healthcare workers are quite low. To maximize influenza vaccine uptake, awareness programs are needed to correct the misconceptions health care workers have about the vaccine, and diverse strategies should be implemented to encourage them to get vaccinated, thereby promoting influenza vaccination.

(Publishing Office of the University of Rzeszow, 2024-06) Şen, Mehmet Ali; Yakıt Ak, Eda
Introduction and aim. Human papillomavirus (HPV) is a common infection responsible for many cancers. This study was conducted to determine the relationship between the knowledge level of HPV and the health literacy of youth living in Türkiye. Material and methods. The study sample comprised 543 youth aged 18 and 30 living in Türkiye. The data were assessed with a questionnaire, the human papilloma virus knowledge scale (HPV-KS), and the health literacy scale (HLS) and the correlation between them. Results. 50.6% of the youth informed that they are aware of HPV, and 54% of the youth know about the transmission mode of HPV. It was determined that knowing HPV increased 1.839 times by being a woman, 1.949 times by being married, and 14.339 times by knowing STIs. The HPV-KS total score average of the youth was low at 14.26±7.04, and the total score average of HLS was high at 107.91±16.81. A positive and significant correlation was found between HPV-KS total score, all sub-factor scores, HLS total score, and all sub-factors total score (p<0.001). Conclusion. Information studies on HPV should be increased by taking advantage of the generality of health literacy.

(Publishing Office of the University of Rzeszow, 2024-06) Kurt, Aylin; Dinç, Fatma; Şan, Emine Güneş
Introduction and aim. The period immediately after leaving the hospital is known as the transition home, which presents a critical time for parents to take on all the responsibilities and care of a child without the support of the hospital environment. The purpose of this study is to culturally adapt the Pediatric Transition Experience Measure (P-TEM) instrument into Turkish and test its validity and reliability. Material and methods. We conducted this methodological study with parents of children who were discharged from the hospital between May 2021 and May 2022. We evaluated linguistic, content, construct, convergent validity, and internal consistency. Results. The P-TEM exhibited a two-factor structure and accounted for 65% of the overall variability. The internal consistency reliability for the transition preparation and transition support subdimensions was 0.779 and 0.793, respectively, while the total measure had a reliability of 0.831. The item-total correlations for the P-TEM ranged from 0.493 to 0.671. Parents who received the highest P-TEM scores experienced a 5.1-point improvement (95% confidence interval: 1.7 to 8.6) in their satisfaction with healthcare services, which was greater than that of parents who reported lower P-TEM scores. Conclusion. It is worth noting that the P-TEM has been validated and has high reliability in Türkiye.

(Publishing Office of the University of Rzeszow, 2024-06) Khandelwal, Richa; Tigga, Mary Jenifa; Metri, Rajashekar; Deshpande, Anand; Tarun
Introduction and aim. This is a prospective interventional study to compare corneal astigmatism before and after pterygium excision with conjunctival autograft, to determine the difference in mean corneal curvatures before and after pterygium excision, to evaluate the safety and efficacy of autologous blood technique, and sutured conjunctival autograft for primary pterygium. Material and methods. Patients were divided into group A – pterygium excision+sutured conjunctival limbal autograft and group B – pterygium excision+autologous conjunctival limbal autograft under local anesthesia. The preoperative and post operative K1 and K2 values and BCVA were noted. Results. There was statistically significant reduction in mean astigmatism at each post operative follow up in group A at 1 week (p=0.0249), 2 weeks (p=0.004), 1 month (p=0.0031) and at 3 months (p=0.0009) and similarly in group B post operative follow up at 1 week (p=0.0011), 2 weeks (p=0.0021), 1 month (p=0.0009) and at 3 months (p=0.0003). Conclusion. Pterygium surgery decreases the cylindrical error and reverts corneal curvatures to normal, thus improving subjective visual acuity. Astigmatism produced by the pterygium is reduced after surgery We found autologous conjunctival autograft is superior than sutural conjunctival autograft. Pterygium causes astigmatism depending upon the size of pterygium it should be surgically removed to prevent obstruction in the vision.

(Publishing Office of the University of Rzeszow, 2024-06) Ożga, Joanna; Skiba, Marcin; Sztuczka, Szymon; Wyka, Michał
Introduction and aim. Aneurysms and arteriovenous malformations (AVMs) are both vascular abnormalities that can occur simultaneously or separately and increase the risk of intracerebral hemorrhage. The aim of this research was to characterize patients with intracranial aneurysms and AVMs. Material and methods. This retrospective research was based on analysis of Digital Subtraction Angiography. The research group consisted of 118 patients. StatSoft STATISTICA 13 was used for the statistical analysis of parameters, such as dimensions and vascularization pattern of vascular abnormalities. Results. The total number of aneurysms described was 168. In addition, 33 patients with cerebral aneurysms were also diagnosed with cerebral AVMs. The average dimensions of the aneurysms were 6.33mm, 95% CI (5.47 7.18) × 4.76mm, 95% CI (4.09, 5.43). The abnormalities were found in the extent of circulation of ACA (anterior cerebral artery) 50 (29.76%), ICA (internal carotid artery) 48 (28.57%), MCA (middle cerebral artery) 26 (15.48%), PCA (posterior cerebral artery) 23 (13.69%). There were 76 (64%) patients with diagnosed single aneurysms and 42 (36%) with multiple. Conclusion. Aneurysms are more likely to occur singly than multiply. The majority are located within the vascularization of the ACA. Aneurysms can coexist with AVMs, which increases the risk of rupture.
Novaluron and indoxacarb induced methemoglobinemia – unveiling a rare poisoning
(Publishing Office of the University of Rzeszow, 2024-06) Shaji, Ijas Muhammed; Mohanty, Chitta Ranjan; Radhakrishnan, Rakesh Vadakkethil; Siddique, Ruby Nahan
Introduction and aim. In India, the utilization of agricultural pesticides for intentional self-poisoning is a prevalent method, and it is associated with substantially higher fatality rates compared to other self-poisoning approaches. Plethora, an agricultural insecticide containing novaluron (5.25%) and indoxacarb (4.5%), has recently been introduced and widely used in India and various other regions for its broad-spectrum lepidopteran control. While there have been documented cases of isolated self-poisoning involving indoxacarb, there is currently no literature reporting incidents of human poisoning specifically related to novaluron. Description of the case. An 83-Year-old male was presented to the emergency department (ED) with a history of consumption of 50 mL of an insecticide suspension concentrate called ‘PLETHORA’ to commit suicide. He had one episode of vomiting and dizziness after the ingestion. There was associated cyanosis, and the patient was put on high-flow oxygen at 10 L/min through a face mask. The patient was diagnosed to have methemoglobinemia and was successfully treated with methylene blue and ascorbic acid. One hour post methylene blue injection showed a methemoglobin level of 1%, and the patient gradually improved. Patients presenting with novaluron and indoxacarb poisoning require supportive treatment as there is no specific antidote. There should be a high index of suspicion for methemoglobinemia in such patients, and timely management is necessary to prevent further complications. The patient was successfully managed and discharged after the 3rd day of admission. Conclusion. The management of patients with novaluron and indoxacarb poisoning primarily involves supportive care, as there is currently no specific antidote available for these substances. Maintaining a high suspicion index for the development of methemoglobinemia and timely management of other complications is crucial for the best possible patient outcomes.

(Publishing Office of the University of Rzeszow, 2024-06) Makkar, Sameer; Rohilla, Smriti; Gupta, Sandeep; Negi, Shabnam; Makkar, Monika
Introduction and aim. An extraoral cutaneous sinus tract of endodontic origin represents a skin condition that appears due to an infection that could be primary or secondary to trauma accompanied by alveolar bony changes. It may be easily misdiagnosed and inappropriately treated due to lack of inadequate expertise on part of medical professionals followed by faulty treatment which can complicate the case further. Description of case. This case report intends to highlight a case of a sixteen-year-old male patient referred for an extraoral cutaneous sinus tract misdiagnosed and insufficiently treated by a general physician followed by general dentists for more than a month due to lack of proficiency in the field of endodontics. The clinical and radiographic examinations confirmed the pulpal origin due to trauma related to permanent mandibular incisors. A combination of non-surgical root canal therapy followed by periapical surgery was performed leading to a significant healing of the lesion. Conclusion. Accurate diagnosis is the key to treat draining sinus tracts of endodontic origin. Root canal treatment and endodontic surgery should be used judiciously for effectively eliminating the pathogens thus providing healing and repair mechanisms a chance to achieve the desired result.

(Publishing Office of the University of Rzeszow, 2024-06) Cevik, Ayfer Bayindir; Andsoy, Işıl Işık; Yıldız, Hicran
Introduction and aim. There is a gap in nursing student understanding, knowledge, and preventive behaviors concerning esophageal cancer. This study aimed to investigate knowledge, risk factors, and preventive behaviors among Turkish nursing students. Material and methods. A descriptive cross-sectional survey was performed. The questionnaire was conducted online over a four-month period. A convenience sample of 688 undergraduate nursing students was recruited from health science faculty at three universities in Türkiye. The survey was performed using a self-administered questionnaire. The reliability coefficients of the knowledge test were calculated, yielding Cronbach’s alpha (0.952), KR-20 (0.952), and KR-21 (0.945), respectively. A significance level p<0.05 was accepted. Results. The mean age of the study group was 20±1.86 (min: 17, max: 32). The study group consists of 487 women (70.8%) and 201 men (29.2%). Most of the study population report never using alcohol and smoking (88.4%, 73.1%, respectively), and reported paying attention to oral hygiene (88.5%). Nursing students had a low family history of EC (0.4%), obesity (10.2%), and vitamin deficiency (19.2%) which are risk factors. Knowledge of esophageal cancer risks was low (x̄=14.34±9.53; Min=0; Max=31). Total knowledge scores have higher for students with complaints of EC, vitamin deficiency, and diagnosis of Human Papilloma Virus disease (p<0.05). Conclusion. This study showed that there are significant gaps in the knowledge of nursing students and these need to be addressed through an improved nursing curriculum. In this context, the study can be used as important evidence and a resource in the issues that should be given priority to in the training and research needed to increase the knowledge and awareness of future nurses about esophageal cancer.

(Publishing Office of the University of Rzeszow, 2024-06) Singhal, Parul; Mittal, Adreena; Dixit, Ritvija
Introduction and aim. Pancytopenia is the simultaneous presence of anemia, leucopenia and thrombocytopenia. The aim of this work was to study the etiological spectrum of pancytopenia in the National capital region of India, and evaluate the relationship of pancytopenia with serum vitamin B12 levels. Material and methods. This study is of a prospective and analytical type conducted on patients attending the outpatient and inpatient department of Santosh Medical College and the Saraswathi Institute of Medical Sciences tertiary care centers in NCR. Complete blood counts and peripheral blood smear examination was used for morphological classification and typing of anemia. Bone marrow aspiration and vitamin B12 estimation was performed where required. Results. The maximum number of pancytopenia cases were etiologically attributed to megaloblastic anemia (64.2%) followed by aplastic anemia (19.8%). Malaria was attributed to 6.6% cases of pancytopenia. Iron deficiency anemia and tuberculosis both accounted for 1.9% of cases. each. A history of drug intake and mixed nutritional anemia each contributed to 2.8% of cases. Serum vitamin B12 levels showed a significant relationship with pancytopenic cases. Conclusion. In our study, the main cause of pancytopenia is megaloblastic anemia which responds very well to treatment if diagnosed correctly in time. A detailed hematological assessment along with vitamin B12 levels should be evaluated in all cases of pancytopenia irrespective of the etiological categorization.

(Publishing Office of the University of Rzeszow, 2024-06) Pletnov, Vadym; Tkachenko, Olexiy; Akimov, Oleh; Mykytenko, Andrii
Introduction and aim. Violation in the salivary glands will inevitably cause changes in periodontium, and periodontitis can disrupt the functioning of the salivary glands. The purpose of the work is to evaluate changes in NO-synthase and arginase activities, pro- and antioxidant balance in rat salivary glands and soft periodontal tissues during administration of bacterial lipopolysaccharide (LPS) and water avoidance stress (WAS) modeling. Material and methods. The experiment was performed on 24 rats. The animals were divided into 4 groups: control, WAS, animals injected intraperitoneally with 0.4 μg/kg of bacterial LPS of Salmonella typhi, WAS+LPS. Results. Water avoidance stress led to decrease of inducible NO-synthase (iNOS) activity in salivary glands by 1.63 times, but decreased arginase activity by 1.15 times, superoxide production increased by 1.53 times, catalase activity decreased by 1.2 times, and malonic dialdehyde (MDA) increased by 1.19 times compared to the control. Lipopolysaccharide led to increase of constitutive NO-synthases (cNOS) activity in salivary glands by 1.48 times, but decreased arginase activity by 6.15 times, catalase activity increased by 2.6 times and superoxide dismutase activity decreased by 2.74 times, and MDA increased by 6.84 times compared to the control. Water avoidance stress + LPS in salivary glands led to decrease of cNOS and arginase activity by 1.09 and 1.19 times, respectively, superoxide production increased by 1.88 times, catalase and superoxide dismutase activity decreased by 1.06 times and 1.34 times, respectively, and MDA increased by 2.44 times compared to the control. Water avoidance stress led to increase of iNOS activity in periodontium by 1.44 times and arginase activity decreased by 1.37 times, superoxide production increased 1.32 times, catalase activity and superoxide dismutase activities decreased by 1.27 times and by 1.53 times, respectively, and MDA increased by 1.31 times compared to the control. Lipopolysaccharide led to increase of iNOS activity in the periodontium by 3.88 times, arginase activity decreased by 2.69 times, superoxide production increased 1.64 times, catalase activity increased by 4.32 times, and MDA increased by 4.51 times compared to the control. Water avoidance stress + LPS in periodontium led to increase of iNOS and cNOS activities by 1.95 times and 1.53, respectively, arginase activity decreased by 1.39 times, superoxide production increased 1.66 times, catalase activity increased by 1.11 times, and MDA increased by 1.53 times compared to the control. Conclusion. The combination of LPS and WAS leads to changes in NO production and oxidative stress in salivary glands and the periodontium.
