Objectives. Popliteal and infrapopliteal artery injuries have significant morbidity and mortality rates, especially in terms of amputation. In our study, we aimed to evaluate patients who operated due to popliteal and infrapopliteal vascular injuries in our clinic. Patients and Methods. Between 2016 and 2023; 21 patients who were operated in our clinic due to popliteal and infrapopliteal artery injuries were retrospectively evaluated. Results. 2 of the patients were female (9.5%) and 19 were male (90.5%). Age ranges were 21–78. The causes of injury were gunshot wounds in 9 patients (42.86%), blunt trauma in 7 patients (33.33%), and sharp object injuries in 5 patients (23.80%). Reversed saphenous vein interposition in 7 patients (33.33%), primary repair in 6 patients (28.57%), 6 mm polytetrafluoroethylene graft (PTFE) interposition in 3 patients (14.28%), end-to-end anastomosis in 2 patients (9.52%), saphenous-PTFE composite graft interposition in 2 patients (9.52%), and embolectomy in 1 patient (4.76%) were performed. Arterial ligation was not performed. Simultaneous orthopedic intervention was performed in 8 patients. Fasciotomy was performed in 3 patients. Venous repair was performed in 5 patients with venous injuries. Vein ligation was not performed. Mortality was observed postoperatively in 1 patient. No patient developed amputation. Foot drop developed with nerve damage in 2 patients. Conclusion. Mortality and morbidity rates may increase in popliteal and infrapopliteal artery injuries in cases of hemodynamic disorder, simultaneous bone fracture, multivessel injury, and nerve transection. These rates can be reduced by appropriate surgical repair and ensuring hemodynamic stability.

Objective:This study aimed to determine the sleep habits and sleep problems of patients with conduct disorder (CD) and to compare them with healthy controls.Materials and Methods:This cross-sectional study included 45 children diagnosed with CD and 50 healthy controls. Sleep was evaluated by children’s sleep habits questionnaire (CSHQ). Qualitative variables between groups were compared using chi-square test, whereas quantitative variables were compared using t-test. Correlation analyses were conducted to evaluate relationships between the quantitative variables. Linear regression analysis was conducted to evaluate the predictors of severity of CD symptoms. P was set at 0.05.Results:The average ages of children in CD and control groups were 11.04±1.20 and 10.00±1.55 years, respectively. Moreover, 71.1% in the CD group were boys (vs. 78.0% in the control group). The groups were comparable in terms of socio-demographic features (all p>0.05). Scores of all CSHQ subscales were significantly elevated in the CD group compared with the control group (p

Background: Orofacial clefts are the most common congenital craniofacial anomalies, globally. However, few reports describe cleft demographic, clinical, and surgical information in a Turkish population. Aims and Objectives: The aim of this study is to investigate the demographic, clinical, surgical information and outcomes of cleft lip and/or palate (CL/P) patients in Northwestern Turkey. Materials and Methods: We assessed demographic, clinical, operative characteristics, and postoperative complications data in this retrospective review of electronic medical records at a tertiary referral center from 2005 to 2015. Results: Our study included 150 CL/P patients (88 men, 62 women). Cleft lip and palate (CLP) was the most prevalent type of cleft (60%), followed by isolated cleft palate (31.3%) and isolated cleft lip (8.7%). The rates of maternal folic acid use, smoking, alcohol intake, and consanguinity were 83.3%, 5.3%, 1.3%, and 3.3%, respectively. Nasoalveolar molding was applied mostly in bilateral—not unilateral—CLP patients. The modified, extended Mohler technique was common for cleft lip repairs. Most cleft palate repairs used Bardach's two-flap palatoplasty combined with radical intravelar veloplasty. Most cases required grommet insertion. For cleft palate patients, myringotomy or paracentesis was performed in 12.8% of repairs, and acellular dermal matrix was used in 28.5% of repairs. Conclusion: Knowledge of CL/P characteristics is crucial for treatment planning and satisfactory health care. To our knowledge, this is the first study to assess CLP data in a Turkish population.

Objective: The epigastric artery perforator flap is commonly used in the breast reconstruction. Ischemia during surgery results in the necrosis of the flap. We aimed to study the effect of fondaparinux in reperfusion injury in perforator flap model and determined its effects on the flap viability. Materials and Methods: Twenty-eight female Wistar Albino rats were included in this study. Rats were separated into three groups: A control (n = 9), B ischemia (n = 9), and C ischemia + drug (n = 10). Superior epigastric artery perforator flap on the single perforator was elevated in all groups. In Group A, flap was sutured back. In Group B, ischemia was applied for 4 h to the pedicle. In Group C, fondaparinux was administered 30 min before the reperfusion of the flap. Serum malondialdehyde (MDA), myeloperoxidase (MPO) levels, and histopathological examination of the flaps were studied. Results: The mean survival areas of flaps were 92.5%, 50.1%, and 91.1% in Group A, Group B, and Group C, respectively. Statistical differences were observed between these values (P < 0.05). The means of MPO and MDA were 22.3 ng/ml and 4.5 nmol/ml; 31.1 ng/ml and 4.7 nmol/ml; 27.1 ng/ml and 4.5 nmol/ml, respectively, for Group A, Group B, and Group C, and no statistically significant difference was found between groups (P > 0.05). Histopathologically, statistically significant difference was found between Group A, Group B, and Group C in terms of the infiltration of the leukocytes with polymorph nuclei (PMNL) for 24 h (P < 0.05). In the histopathological examinations done at the 7th day, statistically significant difference was found between groups in terms of edema, necrosis, increase in connective tissue, and leukocytes with polymorph nuclei (PMNL) (P < 0.05). Conclusion: Administration of fondaparinux after ischemia increased the flap viability in the epigastric artery perforator flap model.

In children and adolescents, especially younger ones, recurrent abdominal pains may develop as a response to psychosocial stressors. They may be considered as functional and be one of the common reasons for clinical referrals. A rare cause of recurrent, organic abdominal pain is abdominal epilepsy. Abdominal epilepsy may be considered in differential diagnosis of patients that were thought to have functional complaints. In this case, a 16-year-old adolescent girl whose chief complaints included loss of consciousness and recurrent abdominal pains lasting for a year is presented.

Enerji tüketiminin azaltılması ülkelerin gelişimi için çok önemlidir. Yapılarda enerji tüketimi bu nedenle büyük önem arz etmektedir.

Enhancing the biocompatibility of biomaterials is a critical aspect of tissue engineering and regenerative medicine. Advances in 3D bioprinting technology, blending natural and synthetic materials for the production of bioink, offer new opportunities to develop highly biocompatible materials that can closely mimic the native tissue environment. In this study, we used pericardial fluid structure (PFS)-based material together with alginate to mimic the extracellular matrix (ECM) and produce a bioink material. Thus, blended alginate with PFS material and MC3T3-E1 pre-osteoblast cell-laden hydrogels characterized by comparing each other, especially alginate hydrogels, and evaluated in terms of biocompatibility for tissue engineering applications. According to the rheological analysis results, all hydrogel groups A, A-PFS (150 mg), and A-PFS (1:1) had viscoelastic properties. Mechanical tests showed that the A-PFS (1:1) hydrogel had the most strength properties. Additionally, the viscosity values of the hydrogel solutions were in an applicable range for use in 3D bioprinters. It was also found out that PFS increased the biocompatibility of alginate-based bioink, in terms of cell proliferation and differentiation. Overall, these findings suggest that alginate and pericardial fluid-based materials can be successfully used for bioink production. The resulting hydrogels exhibit viscoelastic properties, appropriate viscosity for 3D bioprinting, and support cell viability, proliferation, and osteogenic differentiation. This research has the potential not only to produce bioink but also to produce injectable hydrogels and drug delivery systems, which can become biocompatible materials that can be used for tissue engineering and regenerative medicine applications., (© 2024 International Union of Biochemistry and Molecular Biology, Inc.)

In vitro release testing (IVRT) is extensively used to develop the formulation of topical semi-solid products, to evaluate the quality and consistency of the product after scale-up and post-approval changes, and more recently to aid the evaluation of topical generic products' equivalency. The selection of synthetic membrane is one of the most critical parameters of the method development part of IVRT. It is well known that the membrane features namely its polymer matrices, porosity, pore size, thickness can have a substantial effect on the IVRT data. However, there is no detailed information available in the literature regarding the membrane selection for different types of topical dosage forms. Therefore, we aimed to investigate whether difference topical semi-solid dosage forms of the same drug molecule would cause to variation in the membrane selection. Within this framework, rheological behaviour of commercially available three different types of topical semi-solid dosage forms (ointment, cream, and lotion) of mometasone furoate (0.1%) were primarily characterized. Then, the membrane inertness test was conducted using a series of synthetic hydrophilic membranes (regenerated cellulose, cellulose acetate, cellulose nitrate, mixed cellulose ester membranes) and hydrophobic membranes (polyether sulfone, polypropylene, polytetrafluoroethylene membranes) after identifying of an appropriate receptor medium that ensures sink condition for mometasone furoate. Lastly, IVRT studies from the topical semi-solid products were performed utilizing Franz-type diffusion cells. The membrane inertness and in vitro release data demonstrated that the cellulose acetate membrane showed superior diffusion properties in general while the other synthetic membranes exhibited varying outcomes for different semi-solid dosage forms of mometasone furoate. Overall, the results indicated that the release rate and the cumulative drug released amount of drug after 6 h through the different synthetic membranes might vary depending on the semi-solid dosage form. In order to select the synthetic membrane for IVRT, it should also be considered potential interactions between the polymer matrices and the chemical structure of drug molecule as well as formulation components prior to conducting membrane inertness test and IVRT studies., Competing Interests: Declaration of competing Interest There is no conflict of interest with any commercial or other associations in this study., (Copyright © 2024 The Authors.

Background: Food allergy is a public health issue that has a significant impact on the lives of families. Parental self-efficacy/confidence is important in managing food allergies. The aim of this study is to validate the "Food Allergy Self-Efficacy Scale for Parents" (FASE-P) and assess parental self-efficacy in managing their child's food allergy., Methods: Turkish version of the FASE-P (T-FASE-P) was administered to 347 parents of children aged 0-18 who had been followed for at least one month due to food allergy at the Pediatric Allergy Clinic of Prof. Dr. Cemil Taşcıoğlu City Hospital between September 1 and December 31, 2023, through face-to-face interviews and online surveys for parents of children with food allergies from the general population. Content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were conducted to evaluate the validity of the scale. General Self-Efficacy Scale (GSES) was used for concurrent criterion validity. Internal consistency analysis, test-retest application, and item analysis were conducted to assess its reliability., Results: T-FASE-P scale initially contained 21 items, and the Cronbach's alpha coefficient (α) calculated in this form was found to be 0.89. Later, when 4 items were excluded, the 17-item version of the scale was calculated as α=0.90. The intra-class correlation coefficient between the test and re-test was found to be 0.972. The content validity index value of the scale was calculated as 0.99, indicating that the content validity was at a sufficient level. In the EFA, it was determined that the scale formed a three-factor structural model and that this model explained 60.82% of the total variance. As a result of the CFA, the fit indices were calculated as χ2/df=2.341, GFI=0.919, TLI=0.950, indicating a good level of fit. Based on the analysis results, T-FASE-P consists of 17 items and three subscales., Conclusion: T-FASE-P scale is a valid and reliable measurement tool that can be used to determine the food allergy self-efficacy of Turkish parents., Competing Interests: The authors declare that there is no conflict of interest.

RNA methylation adds a second layer of genetic information that dictates the post-transcriptional fate of RNAs. Although various methods exist that enable the analysis of RNA methylation in a site-specific or transcriptome-wide manner, whether biophysical approaches can be employed to such analyses is unexplored. In this study, Fourier-transform infrared (FT-IR) and circular dichroism (CD) spectroscopy are employed to examine the methylation status of both synthetic and cellular RNAs. The results show that FT-IR spectroscopy is perfectly capable of quantitatively distinguishing synthetic m 6 A-methylated RNAs from un-methylated ones. Subsequently, FT-IR spectroscopy is successfully employed to assess the changes in the extent of total RNA methylation upon the knockdown of the m 6 A writer, METTL3, in HeLa cells. In addition, the same approach is shown to accurately detect reduction in total RNA methylation upon the treatment of HeLa cells with tumor necrosis factor alpha (TNF-α). It is also demonstrated that m 1 A and m 6 A methylation induce quite a distinct secondary structure on RNAs, as evident from CD spectra. These results strongly suggest that both FT-IR and CD spectroscopy methods can be exploited to uncover biophysical properties impinged on RNAs by methyl moieties, providing a fast, convenient and cheap alternative to the existing methods.

Objectives: The aim of this retrospective multicenter study was to evaluate the prognostic significance of low muscle mass, and inflammatory markers in patients with stage III nonsmall cell lung cancer (NSCLC) who received definitive chemoradiotherapy (CRT). Furthermore, the study aimed to determine the threshold value of disease-specific low muscle mass., Methods: A total of 461 patients with stage III NSCLC were evaluated. Low muscle mass, prognostic nutritional index (PNI), and biochemical inflammatory markers were assessed. The Kaplan-Meier method and Cox regression analysis were used to analyze overall survival (OS) and progression-free survival (PFS)., Results: This study found a disease-specific low muscle mass threshold of LSMI <38.7 cm²/m² for women and <45.1 cm²/m² for men, with 25.2% of patients having disease-specific low muscle mass. Multivariate cox regression analysis revealed that low PNI was found to be an independent unfavorable prognostic factor for both PFS (HR=0.67; 95% CI: 0.48-0.92, P= 0.015) and OS (HR=0.67; 95% CI: 0.50-0.91, P=0.008). Other factors including ECOG PS 3 (HR=7.76; 95% CI: 1.73-34.76, P=0.007), induction CT (HR=0.66; 95% CI: 0.49-0.88, P= 0.004), and disease-specific low muscle mass (HR=1.40; 95% CI: 1.02-1.92, P= 0.038) also had independent effects on prognosis., Conclusions: The present study provides evidence that the presence of low muscle mass and low PNI significantly impacts the prognosis of patients with stage III NSCLC who undergo definitive CRT. Furthermore, our study is notable for being the first multicenter investigation to identify a disease-specific low muscle mass threshold., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

The purpose of the present research was to assess the amounts of aflatoxin M1 (AFM 1 ) and immunoglobulin (IgA, IgG, and IgM) in cow colostrum samples, as well as their relationship. The sampling involved 90 cows (54 Montofon and 36 Simmental) from 15 independent farms. An appropriate number of samples from the total mixed ration (TMR) used in feeding the cows were collected simultaneously with the colostrum samples. AFB 1 in feed, AFM 1 , and immunoglobulin (IgA, IgG, and IgM) levels in colostrum were evaluated using the ELISA method. The AFM 1 level in colostrum samples exceeded the maximum allowed values for raw milk. Ig levels were higher in Montofon-breed cows' colostrum than in Simmentals. However, it was determined that neither the breed nor the lactation number significantly affected the colostrum Ig level. It was determined that there was no linear relationship between the number of lactations and immunoglobulin levels or between AFM 1 and immunoglobulin levels in colostrum. Similarly, it was determined that there was no linear relationship between the AFB 1 level in the feed and the AFM 1 level in the colostrum of animals consuming these feeds., (© 2024.

Across the world and within Europe, a growing number of consumers are choosing to buy gluten-free products. Motivations for a gluten-free diet and the consequences of consuming gluten are varied, from a medical necessity for those diagnosed with celiac disease to a range of health complications and discomfort for those who are gluten-intolerant. In this research, 7296 gluten-free consumers across 13 European countries responded to an online survey on the 33 types of gluten-free products purchased, how frequently they purchased them, their satisfaction with gluten-free quality and availability, the problems they have experienced, and the strategies they have employed to cope with these problems. The investigation examines whether and how these consumer attitudes and behaviors differ between those diagnosed with celiac disease, those who are gluten-intolerant, and those who are caregivers for others with a gluten-free diet. The results show that significant differences existed for all these habits and issues across the three gluten-free consumer groups. Specifically, caregivers purchased most of the gluten-free product types more frequently than the other two groups, experienced more availability problems, and were more likely to shop at multiple stores or make their own gluten-free products. Celiac-diagnosed consumers tended to buy gluten-free products more frequently than those who are gluten-intolerant, and they tended to be the most satisfied with the quality and range of gluten-free offerings. Despite purchasing frequency differences between the groups, the results suggest a similar hierarchy of gluten-free products that could provide the foundation for a European gluten-free food basket.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases. In this review, we aimed to evaluate the role of multimodality imaging in diagnosis of cardiomyopathies with key images and discussed the effects of genetics on the diagnostic, prognostic, and therapeutic guidance of cardiomyopathies.

There is an increasing incidence of diagnosing both congenital and acquired heart valve diseases in women during pregnancy. Factors such as elevated rates of pregnancy, older maternal age, and coexisting conditions like diabetes, hypertension, and obesity contribute significantly to the symptomatic manifestation and detection of valvular heart diseases in women planning for pregnancy. Pregnancy induces cardiovascular changes across the maternal physiology, posing a heightened risk of morbidity and mortality, especially in women afflicted with valvular heart diseases. In this article, we present a case of a 25-year-old patient who underwent mitral ring annuloplasty surgery at the age of 9. Her echocardiography revealed a mismatch of the mitral ring during a follow-up examination at the age of 20. Despite neglecting further follow-ups, the patient became pregnant and presented to us at the 6th week of pregnancy. She underwent evaluations at the 6th, 10th, and 22nd weeks of pregnancy, as well as before delivery. Following the resumption of follow-up appointments, intervention planning was initiated during the postpartum period. This case exemplifies successful management, resulting in a healthy delivery after navigating through the pregnancy.

Colorectal carcinoma (CRC) is a common cause of mortality 1 , but a comprehensive description of its genomic landscape is lacking 2-9 . Here we perform whole-genome sequencing of 2,023 CRC samples from participants in the UK 100,000 Genomes Project, thereby providing a highly detailed somatic mutational landscape of this cancer. Integrated analyses identify more than 250 putative CRC driver genes, many not previously implicated in CRC or other cancers, including several recurrent changes outside the coding genome. We extend the molecular pathways involved in CRC development, define four new common subgroups of microsatellite-stable CRC based on genomic features and show that these groups have independent prognostic associations. We also characterize several rare molecular CRC subgroups, some with potential clinical relevance, including cancers with both microsatellite and chromosomal instability. We demonstrate a spectrum of mutational profiles across the colorectum, which reflect aetiological differences. These include the role of Escherichia coli pks+ colibactin in rectal cancers 10 and the importance of the SBS93 signature 11-13 , which suggests that diet or smoking is a risk factor. Immune-escape driver mutations 14 are near-ubiquitous in hypermutant tumours and occur in about half of microsatellite-stable CRCs, often in the form of HLA copy number changes. Many driver mutations are actionable, including those associated with rare subgroups (for example, BRCA1 and IDH1), highlighting the role of whole-genome sequencing in optimizing patient care., (© 2024.

This study had two main objectives. The first goal was to examine fathers' parenting styles in a society with traditional patriarchal values. The second goal was to understand the extent to which marital relationship variables (i.e., marital satisfaction and spousal support) are related with the identified fathering profiles. The theoretical and empirical underpinnings of the "parenting styles" literature that form the foundation of the research on parent-child dynamics are still mainly based on data collected only from mothers. This weakness of the literature on fathering typologies is further accompanied by the scarcity of data on fathers' parenting practices from non-Western contexts. To achieve the study aims, a latent profile analysis based on warmth and control dimensions of parenting was performed using a nationally representative sample of 1070 urban fathers in Turkey. Using scores on six parenting behavior variables (i.e., warmth, punishment, inductive reasoning, positive parenting, discipline and teaching responsibilities, time and talking together), results revealed four fathering profiles: "authoritative" (30%), "average" (45%), "uninvolved" (16%), and "disciplining-distant" (8%). Furthermore, the results showed that the fathering profiles significantly differed from each other on the marital satisfaction and spousal support scores. Results highlight the importance of investigating fathering behaviors and their predictors in different cultures., (© 2023 Family Process Institute.)

Objective: High-grade gliomas are aggressive brain tumors with poor prognoses. Understanding the factors that influence their progression is crucial for improving treatment outcomes. This study investigates the prognostic significance of panimmune inflammation in patients diagnosed with high-grade gliomas., Materials-Methods: Data from 89 high-grade glioma patients were analysed retrospectively. The Panimmune inflammation Value (PIV) of each patient meeting the eligibility criteria was calculated on the basis of platelet, monocyte, neutrophil, and lymphocyte counts obtained from peripheral blood samples taken on the first day of treatment. PIV is calculated using the following formula: PIV = T × M × N ÷ L. A receiver operating characteristic (ROC) analysis was employed to identify the optimal cut-off value for PIV about progression-free survival (PFS) and overall survival (OS) outcomes. The primary and secondary endpoints were the differences in OS and PFS between the PIV groups. The Kaplan‒Meier method was used for survival analyses., Results: The ROC analysis indicated that the optimal PIV threshold was 545.5, which exhibited a significant interaction with PFS and OS outcomes. Patients were subsequently divided into two groups based on their PIV levels: a low PIV (L-PIV) group comprising 45 patients and a high PIV (H-PIV) group comprising 44 patients. A comparative analysis of survival rates indicated that patients with elevated PIV had a shorter median PFS of 4.0 months compared to 8.0 months in the low PIV group (P = 0.797), as well as a reduced median OS of 19.0 months versus not available (NA) in the low PIV group (P = 0.215)., Conclusion: Our study results did not reveal a statistically significant association between H-PIV measurements and reduced PFS or OS. However, PIV effectively stratified newly diagnosed high-grade glioma patients into two distinct groups with significantly different PFS and OS outcomes., (© 2024.

Background: Idiopathic intracranial hypertension (IIH) can affect both hearing and balance due to increased inner ear pressure., Aims/objectives: This study aimed to evaluate the impact of increased inner ear pressure on hearing and balance in patients with IIH using auditory and vestibular tests., Material and Methods: Twenty-four IIH patients and 28 healthy controls underwent oVEMP, pure tone audiometry, tympanometry, and acoustic reflex tests pre-lumbar punctures. IIH patients received acetazolamide. Pre- and post-treatment results, tinnitus, and vertigo scores were compared. Post-treatment oVEMP and audiometry results were compared between groups., Results: Pre-treatment oVEMP showed a significant left N1 latency difference ( p  = 0.049). Post-treatment, left ear amplitude ( p  = 0.035) and both ear amplitude ratios ( p  = 0.044 and p  = 0.047) increased significantly. Audiometry had no significant changes ( p  < 0.05). Tinnitus and vertigo scores decreased significantly ( p  ≤ 0.001)., Conclusion: Prolonged oVEMP latency suggests IIH may impact the brain stem and vestibular nerve, while increased amplitude values indicate peripheral vestibular involvement. IIH affects hearing across all frequencies, especially at 4000 Hz, impacting both hearing and balance., Significance: Understanding the effects of IIH on auditory and vestibular functions can guide effective treatments, improving quality of life for patients by addressing both hearing and balance issues.

Objective: This study investigates the importance of bone density, surface area, and diameter of anatomical structures of the superior semicircular canal (SSC), lateral semicircular canal (LSC), posterior semicircular canal (PSC), utricle, and saccule in patients diagnosed with superior semicircular canal dehiscence (SSCD)., Materials and Methods: The bone density, surface area, and diameter of SSC, LSC, PSC, utricle, and saccule were measured and compared between the SSCD group and control group. Fifteen ears in the SSCD group and 60 ears in the control group were evaluated. Additionally, within the SSCD group, the dehiscent and healthy sides were evaluated independently., Results: SSC's bone density was significantly lower in the SSCD group compared to the control group (p = 0.008). No significant differences were found in surface area and diameter between the groups (p > 0.05). While most of the anatomical structures showed no significant difference in bone density between dehiscent and healthy ears (p > 0.05), SSC bone density was significantly lower in affected ears (p = 0.000) in SSCD group., Conclusion: Based on the data obtained in this study, bone density and anatomical structure may be useful in patients diagnosed with SSCD., (© 2024.

Humor can contribute to nursing practices for relieving pain and anxiety in patients with rheumatoid arthritis (RA) during intravenous (IV) biologic treatment. This study used a prospective, randomized controlled study design to investigate the effect of humor on pain and state anxiety in patients with RA receiving IV infusion therapy. Two sample groups were formed: the intervention group (watching a comedy movie) (n = 18) and the control group (usual care) (n = 18). Both groups received IV biologic therapy. A significant difference was found between the groups' pain mean scores, but the effect size was small (P < .001, η² = 0.032). The mean visual analog scale scores decreased in both groups after the treatment; however, it decreased more in the intervention group (P < .001, Md = 2.44) than in the control group (P = .017, Md = 0.83). No significant difference was found between the groups' mean state anxiety scores, and the effect size was irrelevant (P > .05, η² = 0.001). There was a significant decrease in the anxiety levels of both groups (P < .001). During IV biologic infusion therapy, watching comedy movies is recommended as a nursing care intervention for reducing pain in patients with RA in cooperation with other health professionals., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Postpartum blues/postpartum maternal blues is a psychological disorder experienced by mothers with symptoms of postpartum sadness, easy crying, easy anxiety, sensitivity, indecisiveness. The study aimed to examine the effect of music played on newly delivered mothers on postpartum blues., Methods: A prospective, two-arm, randomized controlled study was conducted on n = 82 (41 = control, 41 = music group) mothers who gave birth at term in Trakya University Health Research and Application Center Maternity Service between May and December 2023. The research data were collected through the Personal Information Form, Stein Blues Scale (SBS), and Edinburgh Postpartum Depression Scale (EPDS). The scales used in the study were evaluated four times: postoperative 0-3 h, 12th, 24th, and 36th hours., Results: The postoperative 0-3 h SBS test median of the new mothers in the music group was 19.00, and the 36th hours test median was 2.00, while the postoperative 0-3 h SBS test median of the control group was 21.00, and the 36th hour test median was 13.00. The postoperative 0-3 h EPDS test median of the new mothers in the music group was 22.00, and the 36th hours test median was 0.00, while the postoperative 0-3 h EPDS test median of the control group was 26.00, and the 36th hours test median was 10.00. A significant difference was found in the 12th, 24th, and 36th hours (p < .001). A statistically significant high positive correlation was found between EPDS and SBS in the 12th, 24th, and 36th hours (p < .001)., Conclusions: In the study, it was found that music played to newly delivered mothers reduced postpartum blues and depression levels., Registration: The submission date for a clinical trial protocol is prior to completing participant recruitment and for a systematic review, prior to completing full paper screening.

Revealing the potential of candidate drugs against different cancer types without disrupting normal cells depends on the drug mode of action. In the current study, the drug response of prostate cancer stem cells (PCSCs) to zoledronic acid (ZOL) grown in two-dimensional (2D) and three-dimensional (3D) culture systems was compared using Fourier transform-infrared (FT-IR) spectroscopy which is a vibrational spectroscopic technique, supporting by biochemical assays and imaging techniques. Based on our data, in 2D cell culture conditions, the ZOL treatment of PCSCs isolated according to both C133 and CD44 cell surface properties induced early/late apoptosis and suppressed migration ability. The CD133 gene expression and protein levels were altered, depending on culture systems. CD133 expression was significantly reduced in 2D cells upon ZOL treatment. FT-IR data revealed that the integrity, fluidity, and ordering/disordering states of the cell membrane and nucleic acid content were altered in both 2D and 3D cells after ZOL treatment. Regular protein structures decrease in 2D cells while glycogen and protein contents increase in 3D cells, indicating a more pronounced cytotoxic effect of ZOL for 2D cells. Untreated 3D PCSCs exhibited an even different spectral profile associated with IR signals of lipids, proteins, nucleic acids, and glycogen in comparison to untreated 2D cells. Our study revealed significant differences in the drug response and cellular constituents between 2D and 3D cells. Exploring molecular targets and/or drug-action mechanisms is significant in cancer treatment approaches; thus, FT-IR spectroscopy can be successfully applied as a novel drug-screening method in clinical research., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 Elsevier Inc.

Objective: To search for any morphological variation contributing to aetiopathogenesis and the diagnosis of benign paroxysmal positional vertigo, we measured the sizes of the semicircular canals in patients with and without benign paroxysmal positional vertigo using multidetector computed tomography., Methods: Cranial bone computed tomography images of 30 benign paroxysmal positional vertigo patients and 30 control patients were acquired with a 128-slice computed tomography scanner and a transverse plane with a thickness of 0.67 mm. The inner diameter, height and width of the canals were measured., Results: The width of the anterior semicircular canals, and the width and height of the posterior semicircular canals of the affected ears in benign paroxysmal positional vertigo patients ( n = 30) were significantly greater than in the control patients ( n = 90; p = 0.001, p = 0.023, p = 0.003, respectively)., Conclusion: In benign paroxysmal positional vertigo patients, the posterior and anterior semicircular canals are longer than those in people without benign paroxysmal positional vertigo. These morphological changes may contribute to elucidating the aetiopathogenesis and be used as a radiological sign for diagnosis of benign paroxysmal positional vertigo disease.

Introduction: The relationship between depression and inflammation and the resulting vascular/neuronal damage have been demonstrated in recent studies. In this study we aimed to investigate inflammation and the possible degeneration that can be caused by depression and accompanying vitamin D deficiency using a non-invasive imaging method of optical coherence tomography (OCT)., Methods: Twenty-four healthy controls and 42 drug free major depressive patients matched for age, sex and eye measurements were compared in terms of vitamin D, C Reactive Protein (CRP) and OCT parameters. The Hamilton Depression Rating Scale (HAM-D), The Clinical Global Impressions Scale (CGI) and Global Assessment of Functioning Scale (GAF) were used to assess disease severity., Results: CRP level and choroidal thickness in the major depression group were significantly higher than the healthy controls. Vitamin D level and the ganglion cell layer (GCL) volume was significantly lower in the major depression group compared to healthy controls. Positive correlation was found between HAM-D and CRP in major depressive patients; a negative correlation was found between current attack duration and GCL volume. CGI was positively correlated with CRP and HAM-D. GAS was negatively correlated with CRP and HAM-D., Conclusion: It has been shown that major depression might be an inflammatory disorder with possible degenerative processes observed with OCT and CRP measurements. But longitudinal follow up studies are needed to demonstrate a cause and effect relationship., Competing Interests: Conflict of Interest: The authors declared that there is no conflict of interest., (Copyright: © 2024 Turkish Neuropsychiatric Society.)

Objectives: Popliteal and infrapopliteal artery injuries have significant morbidity and mortality rates, especially in terms of amputation. In our study, we aimed to evaluate patients who operated due to popliteal and infrapopliteal vascular injuries in our clinic. Patients and Methods . Between 2016 and 2023; 21 patients who were operated in our clinic due to popliteal and infrapopliteal artery injuries were retrospectively evaluated., Results: 2 of the patients were female (9.5%) and 19 were male (90.5%). Age ranges were 21-78. The causes of injury were gunshot wounds in 9 patients (42.86%), blunt trauma in 7 patients (33.33%), and sharp object injuries in 5 patients (23.80%). Reversed saphenous vein interposition in 7 patients (33.33%), primary repair in 6 patients (28.57%), 6 mm polytetrafluoroethylene graft (PTFE) interposition in 3 patients (14.28%), end-to-end anastomosis in 2 patients (9.52%), saphenous-PTFE composite graft interposition in 2 patients (9.52%), and embolectomy in 1 patient (4.76%) were performed. Arterial ligation was not performed. Simultaneous orthopedic intervention was performed in 8 patients. Fasciotomy was performed in 3 patients. Venous repair was performed in 5 patients with venous injuries. Vein ligation was not performed. Mortality was observed postoperatively in 1 patient. No patient developed amputation. Foot drop developed with nerve damage in 2 patients., Conclusion: Mortality and morbidity rates may increase in popliteal and infrapopliteal artery injuries in cases of hemodynamic disorder, simultaneous bone fracture, multivessel injury, and nerve transection. These rates can be reduced by appropriate surgical repair and ensuring hemodynamic stability., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2024 Burak Tamteki̇n and Güler Gülsen Ersoy.)

Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes., Methods: The TRAFFIC study is a national, prospective, multicenter, observational registry. The study aims to collect data from at least 1900 patients diagnosed with atrial fibrillation, with the participation of 40 centers from Türkiye. The following data will be collected from patients: baseline demographic characteristics, medical history, vital signs, symptoms of AF, ECG and echocardiographic findings, CHADS2-VASC2 and HAS-BLED (1-year risk of major bleeding) risk scores, interventional treatments, antithrombotic and antiarrhythmic medications, or other medications used by the patients. For patients who use warfarin, international normalized ratio levels will be monitored. Follow-up data will be collected at 6, 12, 18, and 24 months. Primary endpoints are defined as systemic embolism or major safety endpoints (major bleeding, clinically relevant nonmajor bleeding, and minor bleeding as defined by the International Society on Thrombosis and Hemostasis). The main secondary endpoints include major adverse cardiovascular events (systemic embolism, myocardial infarction, and cardiovascular death), all-cause mortality, and hospitalizations due to all causes or specific reasons., Results: The results of the 12-month follow-up of the study are planned to be shared by the end of 2023., Conclusion: The TRAFFIC study will reveal the prevalence and incidence, demographic characteristics, and risk profiles of AF patients in Türkiye. Additionally, it will provide insights into how current treatments are reflected in this population. Furthermore, risk prediction modeling and risk scoring can be conducted for patients with AF.

Background: There may be many risk factors for both youth offending and victimization. In our study, we aimed to compare youth offenders and victims in terms of attachment characteristics, emotion regulation, and mind-reading skills., Methods: This study employed a single-center, cross-sectional, case-control design. Kiddie and Young Adult Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version along with diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, were administered by clinicians. Mind-reading skills were assessed with Reading the Mind in the Eyes task (RMET) and Faces test. Difficulties in Emotion Regulation Scale (DERS) and Inventory of Parent and Peer Attachment-Short Form (IPPA-SF) were used for assessing attachment and emotion regulation properties., Results: : When we compared the two groups in terms of IPPA-SF, DERS, RMET and Faces test, we found that victimized and offending youth did not differ significantly in terms of attachment to peers and communication/trust domains of parental attachment. Youth offenders and victims differed significantly in terms of DERS- Non-acceptance and Goals both ( P = .031 and .045; respectively). Offending youth scored significantly higher in Non-acceptance, while victimized youth scored significantly higher in Goals., Conclusion: : Offending youth were more alienated from their parents, were experiencing problems with emotional acceptance, and had lower theory of mind and emotion recognition skills compared to victimized youth. Therefore, protective interventions supporting parent-adolescent communication/attachment, as well as emotion recognition/regulation and theory of mind skills of youth, may protect children from both victimization and delinquency., Competing Interests: Declaration of Interests: The authors have no conflict of interest to declare., (2023 The authors.)

Aim/objective: The aim of this study was to demonstrate the benefits of the systematic use of nasal cytology and mucociliary clearance in the diagnostic workup of nasal disorders in children with adenoid hypertrophy (AH) to reach a well-defined diagnosis, establish a rational therapeutic approach, avert from complications, and develop the patient's life quality., Materials/methods: In this prospective study, a total of 61 pediatric patients (aged 5-12 years) were evaluated. The case group consisted of 31 children with AH symptoms, while the control group comprised 30 children without AH symptoms.Exclusions included previous adenoidectomy/adenotonsillectomy, cardiovascular/neurological diseases, acute/allergic rhinitis, genetic disorders (e.g., Down syndrome), and immunodeficiency. The control group consisted of children without nasal obstruction symptoms and without AH, who admitted for various reasons. Medical history, examinations, fiberoptic nasopharyngoscopy, cephalometric evaluations, AST, and nasal cytology were conducted., Results: At the end of the study, a significant increase in the mucociliary clearance time was observed in the group with AH compared to the control group (p < 0.05). Although AH may disrupt MCC, there is no correlation between the size of the hypertrophy and MCC time.When the distribution of cells in the nasal cytology is evaluated, no difference was detected between the AH group and control groups., Conclusion: Nasal mucociliary clearance has been found to be decreased, particularly in the presence of significant AH., Competing Interests: Declaration of competing interest None., (Copyright © 2023.

Albendazole is a benzimidazole group drug used alone or in combination with surgery in the treatment of many helminthiasis, especially hydatid cysts. Type 1 hypersensitivity reaction has been reported rarely. Treatment with desensitization has been successfully applied in a few adult patients, however literature information on pediatric patients was not available. Here, we present a pediatric case in which Type 1 reaction occurred due to the use of albendazole during hydatid cyst treatment and undergone desensitization.

The need for foodstuff that emerged with the rapidly increasing world population made fertilizers and pesticides inevitable to obtain maximum efficiency from existing agricultural areas. Sulfoxaflor is currently the only member of the new sulfoximine insecticide subclass of nicotinic acetylcholine receptor agonists. In the study, it was aimed to determine the in vitro genetic, oxidative damage potential, genotoxic and apoptotic effects of three different concentrations (10   µg/mL, 20   µg/mL and 40 µg/mL) of sulfoxaflor insecticide in the cultures of blood lymphocytes. In this study, the single-cell gel electrophoresis (comet), Cytokinesis Block Micronuclues Test (MN test), flow cytometry and measurement of Catalase (CAT) enzyme activity were used to determine genotoxic, apoptotic effects and oxidative damage potential, respectively. It found that there is a decrease in CPBI values and Live cell numbers. It was observed an increase in late apoptotic and necrotic cell numbers, Micronucleus frequency, and Comet analysis parameters (GDI and DCP). There is a significant difference between negative control and all concentration of insecticide for Cytokinesis Block Proliferation Index (CBPI) values and late apoptotic, necrotic and viable cell counts. An increase in CAT enzyme levels was observed at 10 and 20 µg/mL concentrations compared to control., It is found that CAT enzyme activity was inhibited at concentrations of 40 µg/mL. This study is crucial as it is the first study to investigate the impact of Sulfoxaflor insecticide on peripheral blood lymphocyte cells. The genotoxic, oxidative damage, and apoptotic effects of Sulfoxafluor insecticide on the results obtained and its adverse effects on other organisms raise concerns about health and safety.

Introduction: It is aimed to investigate the relationship between the asymptomatic individiuals with elevated HbA1c and occurrence of polyneuropathy by way of comparison to normoglycemic condition., Methods: The study includes 30 female patients diagnosed with subclinical elevation of HbA1c and 30 normoglycemic healthy female patients who applied to our hospital polyclinics with symptoms other than neuropathy between January-March 2017. Nerve conduction examination is done in these patients, parameters of both groups are compared., Results: In regard to amplitude distribution; when compared to control group, tibial motor and ulnar sensory nerve amplitude is lower than the control group (p<0.05). In peroneal, median and ulnar motor nerves, distal latency values are extended compared to control group (p<0.05). Sural, median and ulnar sensory nerve latency is extended compared to control group. In terms of transmission rate distribution; in sural, median and ulnar sensory nerve, transmission speed is lower compared to the control group (p<0.05)., Conclusions: In asymptomatic cases with subclinical elevation of HbA1c, peripheral nervous system involvement is monitored, and early glycemic control should be provided in order to prevent development of neuropathy in patients., Competing Interests: Conflict of Interest: The authors declared that there is no conflict of interest., (Copyright: © 2024 Turkish Neuropsychiatric Society.)

Objectives: To investigate the amount of effective dose (ED) due to the computed tomography (CT) component of lung perfusion-single-photon emission computed tomography (Q-SPECT)/CT., Methods: In this single-center retrospective study, imaging data were collected from the clinic database for the period 2016-2022. The 327 patients identified were aged between 20 and 94 years. Tube voltage, tube current, pitch, gantry rotation time, volume CT dose index, and dose-length product (DLP) were recorded. The DLP was then converted to an ED using the conversion factors. The comparison of the ED between two groups was performed using the Mann-Whitney U non-parametric test., Results: ED (mean ± standard deviation, mSv) was 1.20±0.70 for the pulmonary embolism (PE) (-) and 1.54±1.04 for the PE (+) cases (p<0.05). It was observed that there was a 28% increase in the ED for the PE (+) cases. In addition, each of the PE (-) and PE (+) cases was divided into two groups according to the use of the computed tomography dose reduction (CTDR): without CTDR protocol group (non-CTDR) and with CTDR protocol group (CTDR). For those groups, ED were obtained as 0.87±0.72 and 1.55±0.47 for PE (-) cases (p<0.05); 1.56±1.17 and 1.49±0.54 for PE (+) cases (p>0.05) correspondingly. For a deeper understanding, ED was calculated for all three groups formed with different tube voltage values applied for the non-CTDR and CTDR groups.There was a 42% decrease in the ED for group 1 PE (+) compared to group 2 PE (+) (1.21±0.28, 2.07±0.91, p<0.05) and there was a 41% decrease in the ED for group 1 PE (-) compared to group 2 PE (-) cases (1.17±0.32, 1.97±0.65, p<0.05)., Conclusion: It could be concluded that the effective DR protocol is the non-CTDR protocol for the PE (-) cases and the application of the tube voltage at the level of 100 kVp for the PE (+) cases., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (©Copyright 2023 by the Turkish Society of Nuclear Medicine / Molecular Imaging and Radionuclide Therapy published by Galenos Publishing House.)

Background: Myocardial bridging (MB) and hypertrophic cardiomyopathy (HCM) are associated with the risk of fatal ventricular arrhythmias (VAs). The goal of the study was to determine the relationship between MB and fatal VAs in HCM patients with implantable cardiac defibrillators (ICD)., Methods: A total of 108 HCM patients (mean age: 46.6 ± 13.6 years; male: 73) were enrolled in this retrospective study. All patients underwent transthoracic echocardiography and coronary computed tomography angiography. Fatal VAs including sustained ventricular tachycardia and ventricular fibrillation were documented in ICD records., Results: There were documented fatal VAs in 29 (26.8%) patients during a mean follow-up time of 71.3 ± 30.9 months. Compared with the other groups, the fatal VA group had a higher incidence of the following: presence of MB (82.8 vs. 38%, p < 0.001), deep MB (62.1 vs. 6.3%, p < 0.001), very deep MB (24.1 vs. 0%, p < 0.001), long MB (65.5 vs. 11.4%, p < 0.001), presence of > 1 MB (17.2 vs. 0%, p = 0.001), and MB of the left anterior descending artery (79.3 vs. 17.7%, p < 0.001) . Sudden cardiac death (SCD) risk score (hazard ratio: 1.194; 95% CI: 1.071-1.330; p = 0.001) and presence of MB (hazard ratio: 3.815; 95% CI: 1.41-10.284; p = 0.008) were found to be independent predictors of fatal VAs in HCM patients., Conclusions: The current data suggest that the SCD risk score and presence of MB were independent risk factors for fatal VAs in patients with HCM. In addition to conventional risk factors, the coronary anatomical course can provide clinicians with valuable information when assessing the risk of fatal VAs in HCM patients., (© 2023.

This research focuses on the production and characterization of pristine polyacrylonitrile (PAN) as well as halloysite nanotube (HNT)-doped PAN ultrafiltration (UF) membranes via the phase inversion technique. Membranes containing 0.1, 0.5, and 1% wt HNT in 16% wt PAN are fabricated, and their chemical compositions are examined using Fourier transform infrared (FTIR) spectroscopy. Scanning electron microscopy (SEM) is utilized to characterize the membranes' surface and cross-sectional morphologies. Atomic force microscopy (AFM) is employed to assess the roughness of the PAN/HNT membrane. Thermal characterization is conducted using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA), while contact angle and water content measurements reveal the hydrophilic/hydrophobic properties. The pure water flux (PWF) performance of the porous UF water filtration membranes is evaluated at 3 bar, with porosity and mean pore size calculations. The iron (Fe), manganese (Mn), and total organic carbon (TOC) removal efficiencies of PAN/HNT membranes from dam water are examined, and the surfaces of fouled membranes are investigated by using SEM post-treatment. Mechanical characterization encompasses tensile testing, the Mori-Tanaka homogenization approach, and finite element analysis. The findings offer valuable insights into the impact of HNT doping on PAN membrane characteristics and performance, which will inform future membrane development initiatives., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

Tissue engineering applications are widely used to repair and regenerate damaged tissues and organs. A scaffold, which is an important component in tissue engineering, provides a 3D environment for cells. In this study, the usability of PF components for the production of an ideal scaffold was investigated. For this aim, pericardial fluid (PF) was harvested from the bovine heart, then its structure and components were characterized. The results of Raman spectroscopy analysis, histological staining, and scanning electron microscopy (SEM) shows that the pericardial fluid contains collagen type I and IV, elastin, fibrin, and glycosaminoglycan (GAG), which are native extracellular matrix (ECM) components. The results demonstrated that (i) PF contains native ECM proteins and GAG such as collagen types I, III, and IV, elastin, and fibrin. (ii) The PF is highly similar to the native ECM structure. (iii) PF can significantly contribute to many tissue engineering studies as a native ECM material to increase the biocompatibility of biomaterials and to several in vitro/in vivo cell culture studies. (iv) PF containing multiple ECM molecules, can be used alone or together with hyaluronic acid, poly(ethylene glycol) (PEG), alginate, chitosan, matrigel, and gelatin methacryloyl (GelMA) materials in bioprinting systems for eliminating the disadvantages of these materials., (© 2023 Wiley Periodicals LLC.)

Objective: This study aimed to examine college students' perceived mental health and help-seeking behaviors during the COVID-19 pandemic, as well as to determine the roles of campus mental health climate and institutional support on students' help-seeking behaviors and well-being. Participants: The sample included 123 students from a Northeastern United States University. Methods: Using a web-based survey and convenience sampling, data were collected in late 2021. Results: Most participants retrospectively reported a perceived decline in their mental health during the pandemic. Sixty-five percent of the participants reported that they did not receive professional help at a time when they needed it. Both campus mental health climate and institutional support were negatively related to anxiety symptoms. Greater institutional support predicted less social isolation. Conclusions: Our findings highlight the importance of campus climate and support on students' well-being during the pandemic and the need for increasing students' access to mental health care.

Ketamine is used in medicine because of its anaesthetic and antidepressant effects at low doses. Unfortunately, due to its narcotic effect when used at high doses, its abuse among young people is increasing. It is also one of the most common drugs used in rape. Therefore, there is a need for fast and inexpensive tests that can be performed on-site. With the advancement of nanotechnology, nanoparticle-based approaches have found their place in selective analyses as in many fields. In the developed method, firstly gold nanoparticles were modified with melamine (AuNPs@Mel). Under optimized conditions, hydrogen bonds formed between ketamine and AuNPs@Mel cause the red colour of AuNPs@Mel to shift to blue-purple (i.e. aggregation-induced surface plasmon absorption shift). The association between absorbance and concentration produced a calibration line (curve) having a linearity correlation coefficient of 0.9981 for ketamine concentrations ranging from 4.76 to 47.6 mg L -1 . The detection limit of the proposed method was 1.5 mg L -1 and the RSD (relative standard deviation) values of concentrations were changed ranging from 5.2% to 8.2%. The intra-assay and inter-assay measurements using the suggested method resulted in coefficients of variation (CVs) of 5.7% and 8.5%, respectively. Scan transmission electron microscopy (STEM), UV-vis spectrophotometry and FTIR spectroscopy were used to characterize the synthesized and modified AuNPs. Additionally, the procedure was successfully carried out with some interference materials and a real sample of fetal bovine serum. Lastly, using the Student t-test and F tests, the suggested technique was compared to and confirmed against an LC-MS/MS procedure previously published., (© TÜBİTAK.)
