Background Compared with the general population, the immune response to COVID-19 mRNA vaccines is lower in adult kidney transplant recipients (KTRs). However, data is limited for pediatric KTRs. In this study, we aimed to assess humoral and cellular immune responses to the COVID-19 mRNA vaccine in pediatric KTRs. Methods This multicenter, prospective, case-control study included 63 KTRs (37 male, aged 12-21 years), 19 dialysis patients, and 19 controls. Humoral (anti-SARS-CoV2 IgG, neutralizing Ab (nAb)) and cellular (interferon-gamma release assay (IGRA)) immune responses were assessed at least one month after two doses of BNT162b2 mRNA vaccine. Results Among COVID-19 naïve KTRs (n = 46), 76.1% tested positive for anti-SARS-CoV-2 IgG, 54.3% for nAb, and 63% for IGRA. Serum levels of anti-SARS-CoV-2 IgG and nAb activity were significantly lower in KTRs compared to dialysis and control groups (p < 0.05 for all). Seropositivity in KTRs was independently associated with shorter transplant duration (p = 0.005), and higher eGFR (p = 0.007). IGRA titer was significantly lower than dialysis patients (p = 0.009). Twenty (43.4%) KTRs were positive for all immune parameters. Only four of 11 seronegative KTRs were IGRA-positive. COVID-19 recovered KTRs had significantly higher anti-SARS-CoV-2 IgG and nAb activity levels than COVID-19 naïve KTRs (p = 0.018 and p = 0.007, respectively). Conclusions The humoral and cellular immune responses to SARS-CoV-2 mRNA BNT162b2 vaccine are lower in pediatric KTRs compared to dialysis patients. Further prospective studies are required to demonstrate the clinical efficacy of the mRNA vaccine in KTRs. This prospective study was registered in ClinicalTrials.gov (NCT05465863, registered retrospectively at 20.07.2022).

Despite a plethora of research on vaccine developments and the adverse effects of the vaccineworldwide, there are several research studies on COVID-19 vaccine hesitancy or rejection. The objectives of this study were to investigate the impact of the COVID-19 vaccine on treatment and the factors that contributed to the vaccine concerns. Methods: After one month of being approved by the ethics committee, a descriptive cross-sectional research was conducted using online resources. Samples were randomly selected from the study population. The current study included adults (>18 years old) who were randomly selected from different provinces of Turkey. Results: Most participants were young adults 18–23 years old (47.9%), female (64.8%), married (36.1%), with university education (70.4%), and without medical illness (60.9%) (mean age = 28 years old). Both vaccination doses were given to 53% of the individuals. The most frequent symptom was discomfort at the injection site (0.14%), followed by asthenia muscle pain (0.01%) and edema (24.5%) at the injection site. More symptoms were reported by women than by men. Social media accounts and websites of professional organizations, namely the Dental Association, the Ministry of Health, and the World Health Organization (WHO), were the main sources of COVID-19 information. Hesitancy was induced by concerns about side effects (67.7%), safety (69.7%), lack of information (43.1%), inadequate data on the vaccine clinical trials (55.9%), lack of information on how long protective and effectiveness of vaccines (69.4%), lack of information on how effectiveness against variants (74.8%), think COVID-19 is not dangerous (69.7%), not effectiveness (22.6%) of the vaccine, not safe (32.6%), change my genetic make-up and cause it reproductive sterilite (20.2%), high number of deaths due to COVID-19 (60.8%), the presence of dangerous materials such as aluminum, mercury and others in the content of vaccines, concerns about the country producing the vaccine (38.2%), being afraid of the injection (22%), being against vaccination in general (11%), negative news in the press and social media (38.6%), being risky for only people over 60 (15.9%), having a strong immune system (38.4%), religious (4.7%) and cultural factors (7.4%), believing in natural and traditional medicine (25.4%), and being influenced by friends or family members (19.6%). Hesitancy to accept the COVID-19 vaccine was observed in subjects with hypercholosterolemia and diabetes mellitus. In conclusion, Vaccine hesitancy was primarily related to safety apprehensions. Educational and demographic traits were associated with vaccine admissibility. Doi: 10.28991/ESJ-2023-07-05-022 Full Text: PDF

Objective: The aim of this study is to evaluate the knowledge and awareness levels of patients who have at least one impacted tooth and who had previously applied to the dentist. Study design: This study was conducted in patients aged 15 years and older who applied to Ordu University Faculty of Dentistry for routine examination and agreed to fill out the questionnaire form. A total of 325 people participated in the survey conducted to determine the awareness of patients applying to the faculty of dentistry about their existing impacted teeth. A Pearson's chi-square test was used for hypothesis testing when expected frequencies exceeded 5. Results: It was determined that 56.9 % (185) of the participants were aware of their existing teeth, while 43.1 % (140) were not aware. When the patients were evaluated according to the institutions they had visited, it was seen that the group who were most aware of the presence of impacted tooth were those who apply to the faculty of dentistry (74.4 %). The rate of being informed by dentists in the institutions that they had previously visited was higher in patients with university or post-university graduates (p

Abstract Background This is the first study to report both cortical and trabecular bone evaluation of mandibles in bruxers, within the knowledge of the authors. The purpose of this study was to evaluate the effects of bruxism on both the cortical and the trabecular bone in antegonial and gonial regions of the mandible, which is the attachment of the masticatory muscles, by using panoramic radiographic images. Methods In this study, the data of 65 bruxer (31 female, 34 male) and 71 non-bruxer (37 female, 34 male) young adult patients (20–30 years) were evaluated. Antegonial Notch Depth (AND), Antegonial-Index (AI), Gonial-Index, Fractal Dimension (FD) and Bone Peaks (BP) were evaluated on panoramic radiographic images. The effects of the bruxism, gender and side factors were investigated according to these findings. The statistical significance level was set atP ≤ 0.05. Results The mean AND of bruxers (2.03 ± 0.91) was significantly higher than non-bruxers (1.57 ± 0.71; P

The purpose of the present study was to investigate the antimicrobial effect of propolis ethanol extract collected from the Tarsus district of Mersin province, Kilis province, Yayladagi district of Hatay province in southern Türkiye and Sarkoy district of Tekirdag province of northwestern Türkiye against Escherichia coli (ATCC 25922), Helicobacter pylori (ATCC 43504), Pseudomonas aeruginosa (ATCC 27853), and Staphylococcus aureus (ATCC 29213). Their chemical constituents were detected via liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). They were used in a molecular docking approach to search the interactions between the propolis compounds. A total of 24 phenolic compounds were detected in all samples. 3-4 dimethoxycinnamic acid, caffeic acid and genistein were indicated to be the predominant phenolic compounds in propolis extracts by LC-MS/MS, while rutin was found in the lowest concentration. Phenolic compounds were detected in a high concentration of the propolis samples collected from the Tarsus district of Mersin province. The broth microdilution method determined minimum inhibition concentration (MIC) values. MIC values ranged from 0.02 to 14 mg.mL-1. E. coli and S. aureus examined were as susceptible to the propolis extracts except for Mersin and Tekirdag propolis samples. The propolis sample collected from the Tarsus district of Mersin province presented the highest antibacterial activity on P. aeruginosa with MIC values of 1 mg.mL-1. Active substances in propolis were docked to the relevant target proteins (5LMM, 4NX9, 5YHG, and 5FXT) representing E. coli (ATCC 25922), H. pylori (ATCC 43504), P. aeruginosa (ATCC 27853), and S. aureus (ATCC 29213), and with the help of molecular simulation. With this study, we indicated that the ethanol extract of propolis had a stronger antibacterial activity on S. aureus isolates than that of E. coli, H. pylori, and P. aeruginosa. Although each component of propolis contributed to the antibacterial activity, the contribution of the vitexin component to the antibacterial activity was found to be quite significant.

Abstract Background Varicocele occurs as a result of dilatation of the pampiniform plexus in the spermatic veins. In this study, our primary aim was to evaluate the effect of Transversalis Fascia Plane Block (TFPB) on pain scores in the postoperative period in patients undergoing varicocelectomy surgery, and our secondary aim was to evaluate the effect of TFPB on analgesic consumption. Methods The study was initiated following local ethics committee approval, and sixty ASA I-II patients > 18y scheduled to undergo varicocelectomy and who consented to participation were enrolled. Before the procedure, the patients were randomly assigned two groups: Transversalis Fascia Plan block group (Group TFPB) or surgical incision site infiltration group (Group I).All surgeries were carried out under general anesthesia, and microsurgery using the subinguinal approach. After surgical suturing, TFPB and local infiltration blocks were applied prior to termination of anesthesia.For each block, 20 mL of 0.25% bupivacaine was utilized. Patients' demographic information, passive and active VAS ratings after surgery, usage of non steroidal anti-inflammatory medications and rescue analgesia, and the requirement for rescue analgesia, were recorded. Results A total of 60 patients were included in the study. In terms of demographic data, there was no difference between the groups. At all hours, there was a statistically significant decrease in favor of Group TFPB in terms of active and passive VAS scores (p

Background and Aims: Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that can provide analgesia in the hemithorax, shoulder, and back of the neck. This study aimed to evaluate the post-operative analgesic effect of SPSIPB in patients undergoing video-assisted thoracoscopic surgery (VATS). Methods: It is a double-blind, randomised controlled trial. Twenty-four adult patients who underwent VATS via the uniportal technique were randomised into two groups: the SPSIPB group (n = 12) received SPSIPB along with intravenous patient-controlled analgesia (PCA) with tramadol, whereas the control group (n = 12) received only PCA with tramadol. At the end of the surgery, patients in the SPSIPB group received a unilateral SPSIPB under ultrasound guidance with the use of 30-mL bupivacaine 0.25%. The primary outcome was the numerical rating scale (NRS) scores of the patients. Secondary outcomes included the amount of tramadol and rescue analgesic (paracetamol) consumed by the patients, followed up for post-operative 24 hours. Categorical variables were compared using the Chi-Square Test. Mann–Whitney U Test was used to compare groups of variables that were not normally distributed. Results: The SPSIPB group had lower NRS values during post-operative 24 hours (P < 0.001). Mean (standard deviation) total tramadol consumption was 58.33 (26.23) mg in the SPSIPB group and 144.17 (13.11) mg in the control group (P < 0.001). Rescue analgesic need was lower in the SPSIP group in the first 18 post-operative hours (P < 0.05). Conclusion: Serratus posterior superior intercostal plane block provides good analgesia in the thoracic region after video-assisted thoracoscopic surgery.

Objective: To identify the clinical characteristics and outcomes of hospital-acquired SARS-CoV-2 infection during the vaccination period nationwide in Turkey. Methods: COVID-19 patients followed in the pandemic services across Turkey between January 1, 2021, and March 31, 2022 were investigated retrospectively. Nosocomial COVID-19 was defined as a patient neither diagnosed with COVID-19 nor suspected COVID-19 at the hospital admission and was confirmed COVID-19 ≥5 days after hospital admission. The primary outcome of this study was in-hospital mortality; demographic features and vaccination status was compared between survivors and non-survivors. Results: During the study period, 15 573 COVID-19 patients were followed in 18 centers and 543 (3.5%) patients were nosocomial COVID-19. Most patients with nosocomial COVID-19 (80.4%) were transferred from medical wards. 162 (29.8%) of the patients with nosocomial COVID-19 admitted to the intensive care unit due to disease severity and 138 (25.4%) of the patients died during hospital stay. Advanced age (≥65 years) and number of comorbid diseases (≥2) was found to be associated with mortality in nosocomial COVID-19 (OR 1.74, 95% Cl 1.11-2.74 and OR 1.60, 95% Cl 1.02-2.56, respectively). Vaccination was associated with survival in nosocomial COVID-19 (OR 0.25, 95% Cl 0.16-0.38). Conclusions: Patients with nosocomial COVID-19 had increased admission to intensive care units and higher mortality rate. Vaccination can decrease the in-hospital mortality rate.

In this study, we designed a platform based on a laser-driven approach for fast, efficient, and controllable MOF synthesis. The laser irradiation method was performed for the first time to synthesize Zn-based MOFs in record production time (approximately one hour) compared to all known MOF production methods with comparable morphology. In addition to well-known structural properties, we revealed that the obtained ZnMOFs have a novel optical response, including photoluminescence behavior in the visible range with nanosecond relaxation time, which is also supported by first-principles calculations. Additionally, photocatalytic degradation of methylene blue with ZnMOF was achieved, degrading the 10 ppm methylene blue (MB) solution 83% during 1 min of irradiation time. The application of laser technology can inspire the development of a novel and competent platform for a fast MOF fabrication process and extend the possible applications of MOFs to miniaturized optoelectronic and photonic devices.

International students, often a noteworthy group, constitute about 10 per cent of the student population on many campuses throughout the world (OECD, 2009). At any time, there are likely to be over a million students and scholars attending institutions of higher learning abroad, and recent estimates have set the figure at about 4.5 million (Çetinsaya, G.2014). A significant portion of the contemporary literature has dealt with the problems of international students. Owing to the importance of international students to culturally diverse blend of colleges and universities, higher education institutions must develop support services to assist international students with a series of special needs ranging from adjusting to the academic requirements, to dealing with cultural factors of being drown in new community settings (Cho & Yu, 2015). Leisure, in the meanwhile, is an important experience for university students since it is a functional tool to create socially accommodating environments for this population. However, how active leisure participation impact on social adjustment has not been studied extensively in qualitative studies. Therefore, this qualitative study intended to examine the benefits and impacts of active leisure participation on social adjustment of international students in a mid-size metropolitan university in Manisa, Turkey. Overall, students demonstrated gains in social adjustment and reported psychological and physical benefits when they actively participated in leisure time activities. Study showed that international students have demands and expectations from the university in terms of leisure time activities.

It was aimed to determine the frequency of teachers' encounters with child neglect and abuse and their views on this subject in this study. It is a cross-sectional and descriptive study. Three hundred eighty-eight teachers working in 40 primary schools and 18 high schools were selected with the cluster sampling method. Data was collected through a survey. The Chi-Square tests were applied. 21.6% of the research group reported that they encountered cases of neglect and 46.1% reported cases of abuse. 41.8% of the research group stated that they did not receive child neglect and abuse training. While 26.2% of them find themselves sufficient in diagnosing cases of neglect and abuse, 73.8% find themselves partially sufficient or insufficient. A significant relationship was found between self-efficacy in diagnosing cases according to gender, the number of years of work, receiving education about neglect and abuse, type of abuse, and reporting. While the rate of women who consider reporting suspected child neglect or abuse mandatory is significantly higher than men, the rate of those who find themselves sufficient in diagnosing child neglect or abuse is significantly higher in males. Among the abuse types, the rate of teachers who are faced with the suspicion of sexual abuse in diagnosing the case is significantly higher than the other types of abuse. The rate of teachers receiving training on cases of neglect and abuse and finding themselves competent in this regard is low. Men, those who have worked for 16-20 years, and teachers who have been trained in this subject find themselves more competent in diagnosing child neglect or abuse. Diagnosis the sexual abuse is higher than the other types. Regardless of the incident, the most important factor for teachers to find themselves competent is acquiring knowledge through pre-service or in-service training. [Med-Science 2022; 11(4.000): 1541-7]
