Objective: Onuf's nucleus is an anatomical structure essential in the regulation of urogenital functions. Lumbosacral pathologies may cause changes in urogenital circulation due to Onuf's nucleus injury; however, there is limited evidence corroborating the relationship between spinal cord injury and urethral artery changes.

Materials and methods: We used 23 sexually mature male rabbits-5 rabbits in the control group (GI), 5 rabbits in the sham group (GII), and 13 rabbits in the experimental group (GIII; received autologous blood transfusion into the T12-L1 subarachnoid space to induce subarachnoid hemorrhage (SAH). The GIII underwent a S1-3 laminectomy after 2 weeks and was decapitated. Histologic specimens were prepared to examine changes in Onuf's nucleus, pudendal ganglion, and urethral arteries. The density of damaged neurons and vasospasm index (VSI) in the urethral artery were evaluated.

Results: The mean density of damaged neurons (n/mm3 ) in Onuf's nucleus and pudendal ganglia (S3) and the mean VSI of the 3 groups were as follows-GI: 6 ± 2 per mm3 , 12 ± 4 per mm3 , and 1.63 ± 0.25, respectively; GII: 27 ± 6 per mm3 , 221 ± 62 per mm3 , and 1.97 ± 0.36, respectively; GIII: 154 ± 41 per mm3 , 1890 ± 541 per mm3 , and 3.04 ± 0.95 (P < .05 each for GI/GII, GI/GIII, and GII/GIII). Neuronal damage criteria, such as cytoplasmic condensation and cytoplasmic halo formation, were more prominent in GIII.

Conclusion: SAH can lead to ischemia of the Onuf's nucleus-pudendal nerve structures due to urethral artery spasm, resulting in urogenital complications.

Objective: The aim of this study is to evaluate the relationship between the cochlear nerve and the anatomical structures of the cochlea and internal acoustic canal in patients with congenital hearing loss.

Materials and methods: Temporal tomography and magnetic resonance images of 44 patients (88 ears) with non-syndromic congenital hearing loss were retrospectively analyzed between 2018 and 2021. Patients were divided into 2 groups according to cochlear nerve hypoplasia. Cochlear nerve canal width, cochlear basal/ middle turn widths, and internal auditory canal widths were examined.

Results: Cochlear nerve hypoplasia was detected in 18.2% (n=16) of the patients and all of the patients with cochlear nerve hypoplasia had severe hearing loss. A statistically significant difference was found between the structures' widths in patients with and without cochlear nerve hypoplasia, in cochlear nerve canal and coronal width of the internal auditory canal. When stenosis is accepted as <1.4 mm for cochlear nerve canal and <3.80 mm for coronal width of the internal auditory canal, cochlear nerve hypoplasia differs statistically between the groups in measurements (respectively; P < .001, P=.018).

Conclusions: In patients with sensorineural hearing loss, cochlear nerve hypoplasia may accompany. Anatomical structures are important in predicting cochlear nerve hypoplasia from temporal computed tomography. Cochlear nerve hypoplasia should be suspected if the cochlear nerve canal and coronal width of the internal auditory canal are less than 1.4 mm and 3.8 mm, respectively, on temporal computed tomography.

Objective: The objective of the study was to evaluate the effectiveness of interferential current treatment on a range of motion of joint and shoulder pain, functional status, and quality of life in patients with subacromial impingement syndrome and to compare interferential current with transcutaneous electrical nerve stimulation and sham interferential current.

Materials and methods: Patients complaining of shoulder discomfort participated in the present study. Diagnosis of subacromial impingement syndrome is based on anamnesis, clinical examinations, and shoulder magnetic resonance imaging. A total of 52 patients divided into 3 groups: Group 1 (17 patients, mean age 51.8 years) received interferential current, group 2 (18 patients, mean age 51.8 years) received transcutaneous electrical nerve stimulation, and group 3 (17 patients, mean age 49.1 years) received sham interferential current. Hot pack and exercise treatments were added to all groups. All groups were treated for 3 weeks, 5 times a week, for 15 sessions and 20 minutes for each session. Evaluations were made before treatment (T0), in the middle of treatment (T1; end of 8th session), and at the end of treatment (T2; end of 15th session) using active range of motion and visual analog scale for pain, the Arm, Shoulder, and Hand Problems Questionnaire for functional status, and Short Form-36 for quality of life.

Results: There were significant improvement effects on all of the range of motion, visual analog scale, and the Arm, Shoulder, and Hand Problems Questionnaire scores at T2 and on the scores in some subparameters of Short Form-36 in all groups (P < .05). However, there was no statistically significant difference at T2 between the groups (P > .05).

Conclusion: Interferential current and transcutaneous electrical nerve stimulation exhibited equivalent results regarding range of motion, pain, function, and quality of life of patients with subacromial impingement syndrome, with no significant difference between interferential current and transcutaneous electrical nerve stimulation. Adding interferential current or transcutaneous electrical nerve stimulation treatments to hot pack +exercise therapy did not result in any extra benefits to the patients.

Objective: Based on several studies, atrial remodeling results in an increase in left atrial (LA) stiffness, which is indicative of a worsened reservoir function. A typical microvascular consequence of diabetes mellitus (DM) is diabetic retinopathy. Therefore, the objective of this study was to assess the factors that might be related to LA stiffness in DM patients.

Materials and methods: There were 200 DM patients in the study population. The LA stiffness value of 0.33 led to the division of the patients into 2 groups. According to these groups, the parameters to predict the development of the LA stiffness were investigated.

Results: The patient population's median age was 54.7 ± 9.4 years, and of them, 105 (52.5% of the population) were men. Retinopathy was substantially linked with LA stiffness. Interventricular septum thickness (B coefficient: 0.261, 95% CI 0.128; 0.394; P < .001), mitral annular plane systolic excursion (B coefficient: -0.350, 95% CI -0.489; -0.2212; P < 0.001), and retinopathy (B coefficient: 0.644, 95% CI 0.307; 0.983; P < .001) were identified as independent predictors of the progression of LA stiffness by the linear regression model.

Conclusion: The results of the current investigation demonstrated a correlation between higher LA stiffness values and the presence of diabetic retinopathy in diabetic patients.

Objective: Alzheimer's disease is a neurodegenerative sickness and increasing with age throughout the world. A substantial body of evidence suggests the role of exosomal noncoding ribonucleic acids in the development of Alzheimer's disease, but the regulatory mechanisms mediated by these noncoding ribonucleic acids remain extensively unknown. Using plasma samples from Alzheimer's disease patients, this study explored the exosomal circular ribonucleic acid-microribonucleic acid profiles.

Materials and methods: The ArrayExpress platform was used to convey data from 3 samples from each group (healthy, mild cognitive impairment, and Alzheimer's disease). Using plasma exosomes, differentially expressed microribonucleic acids and differentially expressed circular ribonucleic acids were compared between the Alzheimer's disease and mild cognitive impairment groups. Afterward, to define pathways, gene ontologies, and networks, differentially expressed microribonucleic acids and differentially expressed circular ribonucleic acids common to both mild cognitive impairment and Alzheimer's disease groups were analyzed. Eventually, the selection of hub genes and protein-protein interaction network was analyzed.

Results: A total of common 19 (7 upregulated and 12 downregulated) differentially expressed microribonucleic acids and 24 differentially expressed circular ribonucleic acids were recognized. A total of 4559 target genes were predicted for upregulated differentially expressed microribonucleic acids, while 6504 target genes were identified for downregulated differentially expressed microribonucleic acids, and most of the target genes involved in the phosphoinositide 3-kinases-Akt pathway and that were mostly regulated by hsa-mir-374a-3p, mir-196a-5p, let-205-5p, mir-185-3p, mir-374a-5p, mir-615-3p, let-7c-5p, mir-185-5p. Additionally, 9 hub genes (HSP90AA, ACTB, MAPK1, GSK3B, CCNE2, CDK6, AKT1, IGF1R, CCND1) were revealed as the genes considerably related to Alzheimer's disease by a protein-protein interaction network using the cytohubba in Cytoscape software.

Conclusion: Our findings provide a new perspective on how microribonucleic acids could connect with circular ribonucleic acids in the pathogenesis of Alzheimer's disease.

Objective: Research comparing patients who received liver transplantation (LT) for hepatocellular carcinoma (HCC) has produced varying outcomes regarding survival and disease-free survival. The objective of this study is to determine the factors that influence the disease-free and overall survivals of those who have undergone LT for HCC and to compare the outcomes of living versus deceased donor liver transplants.

Materials and methods: We retrospectively analyzed data on patients aged 18 and above who received LT for HCC from 2006 to 2022. Patients with a follow-up period of less than 6 months and who did not meet the University of California San Francisco criteria were excluded. The data from 58 patients were analyzed. We split the patients into living donor liver transplantation (LDLT) (group 1) and deceased donor liver transplantation (DDLT) (group 2).

Results: The mean age was 56 ± 8.1 years. There were 49 males and 9 females. The median of the alphafetoprotein (AFP) level and model for end-stage liver disease score was 10.1 ng/mL and 11, respectively. The 1-, 3-, 5-, and 10-year disease-free survival rates were 86%, 76.5%, 76.5%, and 76.5%, respectively. The survival rates for the same periods were 94.8%, 74.9%, 70.6%, and 67.4%. The receiver operating characteristic analysis revealed that AFP > 31.8 ng/mL and a total tumor size >3.85 cm raise the likelihood of HCC recurrence post-LT.

Conclusion: Based on the current literature, the overall survival and disease-free survival rates are influenced by factors such as AFP value, total tumor number, and total tumor diameter. In our study, the AFP value and total tumor size had an impact on the recurrence of HCC, and the survival rates were comparable on LDLT and DDLT.

Objective: This study aims to determine the effect of mindfulness stress training given to nurses working during the COVID-19 pandemic period on the quality of work-life and motivation of nurses.

Materials and methods: The research was carried out as a pre-test and post-test control group quasi-experimental model from nurses working in a university hospital in eastern Turkey between September 2021 and December 2021. The study population consisted of 850 nurses working in the hospital. The sample consisted of 42 nurses (21 experimental, 21 control group) who agreed to participate in the study and met the inclusion criteria. In the study, selection bias was controlled by randomized assignment and concealing randomization. The nurses' names were grouped alphabetically and randomized using the research randomizer program. Within the scope of the research, the mindfulness Stress Training Program was applied to the nurses in the experimental group. Data were collected using the Personal Information Form, Nurse WorkLife Quality Scale, and Nurse Work Motivation Scale. Chi-square test, Mann-Whitney U test, and Wilcoxon marking tests were used to analyze the data.

Results: It was determined that the total score of the work motivation scale of the nurses in the experimental group was 48.42 ± 5.39 before the training, 59.52 ± 6.52 after the training, and the total score of the nurse work-life quality scale was 81.00 ± 12.46 before the intervention and 91.08 ± 11.06 after the intervention. The post-test scores of the control and experimental groups were statistically significant (P < .05).

Conclusion: It was found that the Mindfulness-Based Stress Reduction program was effective in nurses' work motivation and quality of work-life during the pandemic period.

Objective: The HEp-2 cell line was first identified as laryngeal cancer cells. Then, it was reported to consist of cervical adenocarcinoma cells derived via HeLa cell line contamination. Styrax liquidus is an exudate that is provided by the injured hull of the Liquidambar orientalis Miller (Hamamelidaceae), which has been used for the treatment of skin problems, peptic ulcers, and parasitic infections or as an antiseptic. In our study, we purposed to research the cytotoxic and apoptotic effect of styrax liquidus on HEp-2 cancer cell line.

Materials and methods: The IC50 dosage of styrax liquidus (Turkish sweet gum obtained from trees) was set by the (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, and the apoptotic effect of styrax liquidus on HEp-2 cancer cell was determined by assessing the expression of genes involved in apoptosis (Bax, Bad, Bak1, p53, Bcl-2, Bcl-XL, Apaf-1, Caspase2, Caspase3a, Caspase9, and Caspase12) by quantitative real-time polymerase chain reaction.

Results: The IC50 value of styrax liquidus was found to be 125 μg/mL for 48 hours. According to the results, styrax liquidus reduced the population of HEp-2 laryngeal cancer cells and increased the expression of genes which were apoptosis related. These results indicate that styrax liquidus can be thought as a choice of cancer therapy.

Conclusion: The finding of the study showed that it would be more useful to perform more qualified studies about the effect of styrax liquidus on cancer cells.

Objective: The Children's Saving Inventory (CSI) is a measurement tool developed to assess hoarding behavior in children. This study aims to investigate the psychometric properties of the Turkish version of the CSI in a clinical sample of children and adolescents.

Materials and methods: The study sample consisted of 52 children and adolescents diagnosed with obsessive-compulsive disorder in the 8-17 age group and their families. As a structured diagnostic interview, the Development and Well-Being Assessment (DAWBA) was applied to all participants included in the research. Hoarding disorder (HD) diagnosis was made clinically by considering the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnostic criteria. The Children's Yale-Brown Obsessive- Compulsive Scale Symptom Checklist (CY-BOCS) was administered by an experienced clinician. The parents and children filled out the Obsessive-Compulsive Inventory-Child Version (OCI-CV) and CSI scales independently.

Results: The 20-item CSI Turkish version demonstrated good internal consistency. This 4-factor structure of the scale was confirmed by confirmatory factor analysis. Children's Saving Inventory showed convergent and discriminant validity with the OCI-CV and CY-BOCS subscales, and the higher CSI total scores in children and adolescents diagnosed with HD confirmed the construct validity.

Conclusion: These findings support the use of the CSI Turkish version as a valid and reliable scale to investigate the hoarding behavior of children and adolescents in a clinical sample. In addition, the CSI Turkish version is currently the only validated instrument to evaluate hoarding behavior in children and adolescents, as rated by parents in Türkiye.

Objective: Superb microvascular imaging is a Doppler technique that increases the visibility of small vessels and gives quantitative information about tissue blood supply by measuring the vascular index. In this study, it is aimed to evaluate the long-term and postradiotherapy changes in blood flow of buried de-epitelized flaps in breast reconstruction by using the quantitative values obtained through superb microvascular imaging.

Materials and methods: Retrospective review of the 14 patients who underwent nipple-sparing breastconserving surgery and immediately breast reconstruction with a de-epitelized extended latissimus dorsi flap was done. In order to demonstrate the effect of radiotherapy on flaps microvascular circulation, patients were evaluated using superb microvascular imaging postoperative first week, first month, and postradiotherapy first week and sixth month. The normal distribution of the data was evaluated with the Shapiro-Wilk test. Paired samples t-test was used for comparisons.

Results: According to the paired samples t-tests, postoperative first week mean vascular index was higher than postoperative first month and postradiotherapy first week (P < .05). Besides, postradiotherapy first week mean vascular index was higher than postoperative first month and also than postradiotherapy sixth month (P < .05).

Conclusion: Radiotherapy can affect the results of breast reconstruction by endothelial and fibrotic injury. In this study, the changes in the microvascular circulation of the latissimus dorsi flap were discussed and found to increase at postoperative and postradiotherapy early period related to inflammation and not decreased significantly at long-term follow-up after radiotherapy.
