Radiographic assessment of incidental bone lesions of the proximal humerus: a prevalence study.

BACKGROUND: An increased prevalence of benign lesions has been associated with the increased use of radiological tools in orthopedic practice. PURPOSE: To investigate the inter-observer reliability of the radiographic detection of lesions on the proximal humerus between different observers. MATERIAL AND METHODS: X-ray radiological examinations of 17,243 patients were performed by an orthopedic surgeon to assess the presence of proximal humeral bone lesions. After this initial screening, 201 patients with lesions were identified and these 201 scans were assessed by three different physicians: an orthopedic oncologist, an orthopedic surgeon, and a musculoskeletal radiologist. Of the 201 patients with lesions, 80 had magnetic resonance imaging in addition to X-rays and were assessed. The diagnosis of the lesions was determined by each participant according to their radiological appearance to assess inter-observer reliability. RESULTS: The prevalence of proximal humeral lesions was determined by the orthopedic surgeon to be 1.165% (201 of 17,243 patients). In 201 patients with a lesion, the mean age was 48 ± 17 years (range = 18-91 years). According to the assessments of the orthopedic oncologist, orthopedic surgeon, and musculoskeletal radiologist, the most common bone lesion identified was enostosis, with prevalence percentages of 53.7%, 59.7%, and 64.7%, respectively. A noteworthy consensus exists in the collective diagnosis of bone lesions among the three investigators, demonstrated by a substantial agreement with Fleiss' κ at 0.74 (P < 0.001). CONCLUSION: There was remarkable agreement between the three investigators on the collective diagnosis of bone lesions. Enostosis was the most common bone lesion at the proximal humerus in our series.

The impact of Reiki practice on episiotomy recovery and perineal pain: A randomized controlled study.

Energy therapies are complementary methods focused on revealing the existing energy and restoring the individual's (recipient's) energy. The aim of this study was to investigate the impact of Reiki practice applied to postpartum women who had spontaneous childbirth without instrumental delivery on postpartum episiotomy recovery and perineal pain. The research was randomized controlled at a hospital in pre-test post-test design. 86 postpartum women in total were included in the research, (n=40) in intervention group and (n=46) in control group. On the postpartum 1st day, 2nd day, 7th day and 14th day, episiotomy recovery of the intervention and control group was assessed with REEDA Scale and perineal pain was assessed with Short Form McGill Pain Questionnaire. The tree sessions of Reiki for 35-40 minutes were applied to intervention group on the postpartum 1st day, 2nd day and 7th day. (Clinical Trial Registry and Registration Number: NCT05486624). The REEDA Scale average oedema scores of the control group postpartum women were higher than intervention group. The control group had higher pain average than the intervention group. The Reiki applied to postpartum women who had spontaneous childbirth without instrumental delivery had a positive impact on episiotomy recovery due to its impact on oedema and it reduced perineal pain.

Les thérapies énergétiques sont des méthodes complémentaires axées sur la révélation de l'énergie existante et la restauration de l'énergie de l'individu (du destinataire). Le but de cette étude était d'étudier l'impact de la pratique du Reiki appliquée aux femmes en post-partum ayant eu un accouchement spontané sans accouchement instrumental sur la récupération par épisiotomie post-partum et les douleurs périnéales. La recherche a été randomisée et contrôlée dans un hôpital selon une conception pré-test et post-test. Au total, 86 femmes en post-partum ont été incluses dans la recherche, (n = 40) dans le groupe d'intervention et (n = 46) dans le groupe témoin. Les 1er, 2e, 7e et 14e jours post-partum, la récupération par épisiotomie du groupe d'intervention et du groupe témoin a été évaluée avec l'échelle REEDA et la douleur périnéale a été évaluée avec le questionnaire abrégé sur la douleur de McGill. Les séances d'arbres de Reiki pendant 35 à 40 minutes ont été appliquées au groupe d'intervention les 1er, 2e et 7e jours post-partum. (Registre des essais cliniques et numéro d'enregistrement : NCT05486624). Les scores moyens d'œdème sur l'échelle REEDA des femmes en post-partum du groupe témoin étaient plus élevés que ceux du groupe d'intervention. Le groupe témoin présentait une douleur moyenne plus élevée que le groupe d'intervention. Le Reiki appliqué aux femmes en post-partum ayant eu un accouchement spontané sans accouchement instrumental a eu un impact positif sur la récupération par épisiotomie en raison de son impact sur l'œdème et de la réduction des douleurs périnéales.

Isolation, identification, and in vitro probiotic characterization of forty novel Bifidobacterium strains from neonatal feces in Erzurum province, Türkiye.

BACKGROUND: Neonatal feces are one of the most important sources for probiotic isolation. The purpose of this study was the isolation and identification of Bifidobacterium spp. from neonatal feces and the evaluation of in vitro probiotic properties of strains including safety tests. RESULTS: A total of 40 isolates were obtained from 14 healthy newborns' feces in Erzurum province, Türkiye. By their rep-PCR patterns and 16S rRNA gene sequences, isolates were identified as 26 Bifidobacterium breve and 14 Bifidobacterium longum. Fifteen of the isolates tolerated bile salts and showed high resistance to simulated gastric juice. Isolates exhibited varying rates of auto-aggregation and hydrophobicity. In addition, most of the isolates displayed antibacterial activity against Escherichia coli O157:H7, Staphylococcus aureus ATCC 29213, Salmonella Typhimurium RSHMB 95091, and Pseudomonas aeruginosa ATCC 9027. However, only one strain showed bile salt hydrolase activity and two strains showed the ability to produce H2O2. Bifidobacterium strains were generally sensitive to the tested antibiotics and lacked kanamycin, gentamicin, and streptomycin resistance genes, and hemolytic and DNAse activities. On the other hand, it was determined that five strains had various virulence genes including gelE, esp, efaAfs, hyl, and ace. CONCLUSION: Results of the present study suggested that B. longum BH28, B. breve BH4 and B. breve BH5 strains have the potential as probiotic candidates for further studies. © 2024 The Authors.

Does resveratrol reduce cisplatin-induced ovarian damage?

OBJECTIVE: The objective of this study was to investigate the protectiveness of resveratrol on cisplatin-induced damage to the ovary using experimental models. METHODS: A total of 30 female Wistar-Albino rats constituted the research material. The rats were categorized into three groups: Group 1 was administered one milliliter of 0.9% NaCl solution, Group 2 was administered 7.5 mg/kg cisplatin, and Group 3 was administered 7.5 mg/kg cisplatin and 10 mg/kg resveratrol. Ovaries were extirpated in all groups and subjected to biochemical and histopathological tests. Cisplatin-induced damage to ovarian tissue was graded and scored as the total histopathological findings score. The ovarian function was assessed using immunohistochemical staining for c-kit expression. Rats' malondialdehyde, catalase, and superoxide dismutase levels were determined. RESULTS: The histopathological finding score was significantly higher in Group 2 than in other groups (p<0.05). The superoxide dismutase and catalase levels were significantly higher in Group 3 than in Group 2 (p<0.001 for both cases). The malondialdehyde level was significantly higher in Group 2 than in Group 3 (p<0.001). CONCLUSION: The study findings demonstrated that resveratrol reduced ovarian injury and enhanced biochemical parameters following cisplatin-induced ovary damage in experimental models.

Utilizing linkage-specific ethyl-esterification approach to perform in-depth analysis of sialylated N-glycans present on milk whey glycoproteins.

Glycosylation of milk whey proteins, specifically the presence of sialic acid-containing glycan residues, causes functional changes in these proteins. This study aimed to analyze the N-glycome of milk whey glycoproteins from various milk sources using a linkage-specific ethyl esterification approach with MALDI-MS (matrix-assisted laser desorption/ionization-mass spectrometry). The results showed that the N-glycan profiles of bovine and buffalo whey mostly overlapped. Acetylated N-glycans were only detected in donkey milk whey at a rate of 16.06%. a2,6-linked N-Acetylneuraminic acid (a2,6-linked NeuAc, E) was found to be the predominant sialylation type in human milk whey (65.16%). The amount of a2,6-linked NeuAc in bovine, buffalo, goat, and donkey whey glycoproteomes was 42.33%, 44.16%, 39.00%, and 34.86%, respectively. The relative abundances of a2,6-linked N-Glycolylneuraminic acid (a2,6-linked NeuGc, Ge) in bovine, buffalo, goat, and donkey whey were 7.52%, 5.41%, 28.24%, and 17.31%, respectively. Goat whey exhibited the highest amount of a2,3-linked N-Glycolylneuraminic acid (a2,3-linked NeuGc, Gl, 8.62%), while bovine and donkey whey contained only 2.14% and 1.11%, respectively.

Cortices of Fibula and Tibia Can Provide Landmarks for Accurate Syndesmosis Fixation Angle: Computed Tomography Validation of Angle Bisector Method.

Anatomic syndesmosis reduction is necessary to restore ankle biomechanics and prevent poor clinical outcomes, but malreduction can be encountered frequently since the ideal fixation angle varies between patients and fixation levels. This study aimed to validate the angle bisector method to reveal whether it provides an accurate syndesmotic fixation angle that is patient- and level-specific. Lower extremity CT angiography of 50 consecutive patients (25 male, 25 female) without evident ankle pathology were evaluated. The average age was 52.8 (±18, range: 18-75). Lines tangent to anterior and posterior cortices of tibia and fibula were drawn in the axial plane at both 2 cm and 3.5 cm above the ankle joint line. Bisection of the angle formed between these lines was drawn and its relationship with the centroidal axis, which is proposed to be the ideal syndesmotic axis, was evaluated. The angle between the bisector line & the centroidal axis and the distance between their most lateral intersections with the fibula were calculated. The measurements were made by 3 blinded observers. Intra- and interobserver reliability analyses were conducted. The average centroidal axis-bisector angle was 2.1° ± 2.1° at 2 cm and 0.6° ± 1.3° at 3.5 cm level. The average distance to the actual syndesmosis entry point was 1.0 ± 0.9 mm at 2 cm and 0.4 ± 0.4 mm at 3.5 cm level. The values didn't show any significant difference according to gender. Intra- and interobserver reliability analysis showed excellent correlation in all parameters (interclass correlation coefficient > 0.90). Angle bisector method was found strongly reliable providing accurate direction for syndesmotic axis. It can provide a patient- and level-specific angle for the application of syndesmotic implants without increasing the fluoroscopy exposure. Its use can have a broad impact on functional outcomes of ankle injuries by decreasing the malreduction rates. Further cadaveric validation and safety studies should be conducted for possible clinical usage.

Clinical trials and promising preclinical applications of CRISPR/Cas gene editing.

Treatment of genetic disorders by genomic manipulation has been the unreachable goal of researchers for many decades. Although our understanding of the genetic basis of genetic diseases has advanced tremendously in the last few decades, the tools developed for genomic editing were not efficient and practical for their use in the clinical setting until now. The recent advancements in the research of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated protein (Cas) systems offered an easy and efficient way to edit the genome and accelerated the research on their potential use in the treatment of genetic disorders. In this review, we summarize the clinical trials that evaluate the CRISPR/Cas systems for treating different genetic diseases and highlight promising preclinical research on CRISPR/Cas mediated treatment of a great diversity of genetic disorders. Ultimately, we discuss the future of CRISPR/Cas mediated genome editing in genetic diseases.

Placental and Umbilical Cord Blood Oxidative Stress Level and Telomere Homeostasis in Early Onset Severe Preeclampsia.

OBJECTIVE: Although the etiopathogenesis of preeclampsia (PE) is unknown, evidence suggests that it may be associated with increased oxidative stress. Studies have shown that oxidative stress can affect DNA fragments called telomeres. However, the interactions of PE, oxidative stress, and telomere length are not clearly known. This study aims to evaluate the oxidative/anti-oxidative stress balance in the placenta and umbilical cord and examine the effect of oxidative stress on telomeres. MATERIALS-METHOD: Cord blood and placental samples were collected from 27 pregnant women with severe PE (280/7-336/7 gestational weeks) and 53 healthy pregnant women. Telomere length (TL) was measured by real-time PCR in the cord blood and placenta tissue. Total antioxidant status (TAS) and total oxidant status (TOS) levels were measured in the cord blood and placenta tissue using a colorimetric method. RESULTS: No significant differences were found between groups regarding age, BMI, gravida, parity, and newborn gender (p>0.05). Cord blood and placental TL of PE patients were significantly shorter than the control group, while cord blood and placental TAS and TOS levels were higher (p<0.05). The results of a multivariate logistic regression analysis showed that the level of placental TOS in PE patients (OR=1.212, 95% CI=1.068-1.375) was an independent risk factor affecting PE. CONCLUSION: This study found that oxidative stress is an independent risk factor in the development of PE and shortens TL in both placental and umbilical cord blood. Future research on telomere homeostasis may offer a new perspective for the treatment of PE.

Determining attitudes toward e-learning: what are the attitudes of health professional students?

Aim: The research was carried out to determine the attitudes of nursing undergraduate students toward e-learning implemented during the COVID-19 pandemic. Subject and methods: The study sample consisted of 320 undergraduate students studying at the Faculty of Health Sciences, Nursing Department of a state university. Personal Information Form and the Test of e-Learning Related Attitudes were administered to the research participants. Results: Of the students, 68.8% were female and 51.6% were between the ages of 21-24. The attitude of 55.3% (177) toward e-learning is negative. Attitude scores of students aged 25-29 were significantly higher compared to those aged 17-20 and 21-24 years old (p = 0.002). The attitude scores of the students who have a computer are significantly higher than those who do not (p = 0.001). Most students did not agree with the statement "E-learning will provide me with better learning opportunities than conventional learning methods." (disagree n = 121; 37.8%, strongly disagree n = 110; 34.4%). Conclusion: It is noticed that e-learning is not sufficient in subjects such as conducting clinical and laboratory practices in health sciences fields with practical training like nursing, and students' attitudes are generally negative. For undergraduate health sciences education, face-to-face and online education for support purposes can be used together in theoretical courses. In addition, it is recommended to use effective online communication techniques in online courses.

Factors that affect placental retinol transfer in preterm infants and mothers with retinol deficiency.

BACKGROUND: The retinol level and retinol delivery to the placenta may vary depending on various factors involving the mother and newborn. The present study evaluates the factors affecting retinol levels in newborns and the transplacental retinol passage in preterm newborns. METHODS: In this prospective cohort study, the retinol and retinol binding protein (RBP) in the umbilical cord blood of 44 preterm infants with a gestation age of <30 weeks were studied. Serum retinol and RBP levels were determined using an enzyme-linked immunosorbent assay, and the rate of transplacental retinol passage was calculated. The demographic data of mothers and newborns, the use of vitamins by the mother, the application of antenatal corticosteroids, and any diseases diagnosed during pregnancy were recorded. An evaluation was made of the retinol, RBP, and other factors of the mother and newborn affecting transplacental retinol passage. RESULTS: A retinol deficiency was identified in 68.2% of the study population. Retinol and RBP levels in umbilical cord blood (273.7 ± 150.03 ng/mL, 7.88 ± 5.6 ng/mL, respectively) were significantly higher than the corresponding levels in the mother (206.4 ± 86.26 ng/ mL, 1.04 ± 0.97 ng/mL, respectively). Umbilical cord blood retinol deficiency was more common in the male participants, while the transplacental retinol passage rate was higher in females. The umbilical cord blood RBP was found to be lower in those administered antenatal corticosteroids than in those who did not receive antenatal corticosteroids, and median maternal RBP levels were lower in patients with anemia and pregnancy-induced hypertension than in those with no disease. DISCUSSION: Placental adaptation and contributing factors may vary in populations with severe retinol deficiency. The finding of significantly increased cord blood retinol levels when compared to maternal retinol levels in the present study suggests that some compensatory mechanisms, such as increased placental RBP levels, support the presentation of retinol to the fetus, even if the mother has a retinol deficiency.

Brucellosis in pregnancy and its response to the changing immunoglobulin A: A prospective controlled study.

Objective: This study aimed to define the rare Brucella infection in pregnancy and its effects on immunoglobulins (Ig). Materials and Methods: This prospective study has conducted Brucella screening using the Rose Bengal test on pregnant and non-pregnant outpatients who did not show any specific Brucella symptoms. The immunoglobulin levels were measured using the enzyme-linked immunosorbent assay. The study group consisted of pregnant women who were at 20 weeks or below gestation and applied to our hospital outpatient clinic for routine check-ups. The control group consisted of healthy patients who applied for routine controls. Results: This study included a total of 584 participants, 293 of whom were controls and 291 were the study (pregnant) participants. The study revealed a 1.5% incidence of Brucella during pregnancy. In acute and chronic Brucella infection, lower levels of IgA response were observed in pregnant cases compared to the control group. Conclusion: Brucella infection is a disease that can cause fetal problems, especially in endemic areas. The role of the altered IgA response in pathologies that are associated with Brucella infection stands out as a new target for disease pathophysiology.

Significant differences were found in the Status Anxiety Scale scores and trait anxiety scale scores according to self-isolation status (P < .05). A significant difference was found in terms of state anxiety scale and trait anxiety scale according to happiness status (P < .05). The problem-based coping scores of those who were happy with the Stress Coping Scale were higher than those who were not happy (P < .05). The state anxiety scale of the students was 42.54, and the trait anxiety scale was 45.16.Nursing students' status and sustained Anxiety Scale scores were moderate. It is important for individuals to have good family and friends and to be happy in the process of the Corona Virus Disease pandemic.

Characteristics and research trends of 50 most-cited hallux rigidus papers.

BACKGROUND: The bibliometric studies in the field of orthopaedics have gained popularity since they can determine the characteristics and research trends of most influential papers in specific subjects. This study aimed to evaluate the 50 most-cited articles related to hallux rigidus, and analyze possible factors associated with increased citation counts. METHODS: The available literature about hallux rigidus on Web of Science database until January 2021 were analyzed and the 50 most-cited articles were determined. The characteristics of the papers were documented and analyzed for any relationship or correlation with total citation or citation per year (citation density) values. RESULTS: The average citation number and citation density were 52.8 (range: 26-243) and 3 (range: 0.8-12.8), respectively. The average author number was 3.4, while the average institution number was 1.9. The USA had the highest number of articles with 29. Twenty-six papers were case-series, only 3 studies had level 1 and only 2 had level 2 evidence. The highest number of articles were published in Foot and Ankle International with 22 papers. Forty papers were clinical studies while 10 were reviews. Five studies were multicentric. CONCLUSION: This study provided the general characteristic and research trends of 50 most influential hallux rigidus papers. The number of institutions and references were positively correlated with citation density, indicating a higher chance of getting cited for papers with collaborations from different institutions and papers using more references from other works. Publication year was also positively correlated with citation density, indicating the better performance of more recent articles. LEVEL OF CLINICAL EVIDENCE: Level 3.

Examining the Knowledge Level of the Nurses and Midwives Had Neonatal Resuscitation Program (NRP) Practitioner Training Course.

BACKGROUND AND PURPOSE: The aim of this study was to investigate the knowledge level of nurses and midwives about the level of knowledge about neonatal resuscitation and the effect of education on knowledge levels. METHODS: The research was applied in January 2016 to the nurses and midwives who worked in neonatal intensive care units, gynecology and maternity wards at Cukurova University Balcali Hospital, Adana Numune Training and Research Hospital, Adana Maternity and Children Diseases Hospital, and had received Neonatal Resuscitation Program practitioner training course. All of the target populations were included in the research before the sample was determined. Data were collected using a questionnaire form consisting of 40 questions including sociodemographic information and knowledge level related to NRP. RESULTS: It was determined that the nurses and midwives answered the questions correctly related to oxygen usage (98.1%) and all the things that should be conducted in order to prevent heat loss in baby (98.1%). It was determined that NRP knowledge points of nurse/midwives were intermediate level as 23.06 ± 3.47 (min: 12; max: 30) and most of the participants (37%) had got NRP course in the last 4-5 years. There was a statistically significant difference between participating time to NRP practitioner training course and working years (p < 0.05). IMPLICATIONS FOR PRACTICE: Systematic repetition of knowledge and skills through in-service training programs is important, as it will lead to a reduction of mortalities of newborns. IMPLICATIONS FOR RESEARCH: It was observed that the knowledge points were quite good considering that the participants of the NRP practitioner-training course had taken the course in the last 4-5 years.

Increased serum myonectin and irisin levels with myonectin and FNDC5 expressions in polycystic ovary syndrome: a case control study.

The aim of this study is to assess the FNDC5 and myonectin expressions and serum levels of myonectin and irisin in women with PCOS. 90 participants were included in this case-control study. 45 of these participants were with PCOS, and 45 of them were healthy volunteers matched for age and body mass index (BMI). Serum irisin and myonectin levels were measured with commercially available enzyme-linked immune sorbent assay (ELISA) kits. Expression of the myonectin and FNDC5 genes were determined by RT-PCR analysis. It was found out that FSI, HOMA-IR, LH, LH/FSH, TT, serum irisin and serum myonectin levels, myonectin mRNA expression, and FNDC5 mRNA expression were higher in the PCOS group, whereas HDL-C level was lower in the PCOS group (p < .05). When the groups were compared, it was detected that IR and HA were significantly higher in the PCOS group (p < .05). Serum irisin and myonectin levels, and myonectin and FNDC5 mRNA expressions were increased in women with PCOS. These molecules can be target molecules in PCOS pathophysiology and treatment.IMPACT STATEMENTWhat is already known on this subject? Although the aetiology of PCOS is not fully understood, it is thought that insulin resistance may play a critical role. In recent studies, the relationship of cytokines secreted from skeletal muscle with insulin resistance has been shown. The effects of irisin and myonectin, which are members of the myokine family, on lipid and glucose metabolism are known.What do the results of this study add? Although there are many studies in the literature regarding serum irisin levels in women with PCOS, their results are confusing. There is a study in the literature investigating the relationship between myonectin and PCOS. In our study, we evaluated myonectin and FNDC mRNA expressions in addition to serum irisin and myonectin levels. As a result, we found that markers and their mRNA expressions were lower in patients with PCOS compared to controls.What are the implications of these findings for clinical practice and/or further research? We think that the results of our study will shed light on future studies. Due to their effects on adipose tissue, these markers may play a role in the aetiology of long-term complications of PCOS. Moreover, they can become pharmacological targets in preventing these complications.

Dual energy CT in necrotizing enterocolitis; a novel diagnostic approach.

BACKGROUND: Necrotizing enterocolitis (NEC) is one of the most important causes of morbidity and mortality in premature infants. Although there are no specific diagnostic tools, the main factors affecting prognosis are clinical and laboratory findings, and early diagnosis and treatment. In this study, we demonstrate the importance of dual-energy computed tomography (DECT) in confirming intestinal ischemia in neonates with NEC. METHODS: Patients diagnosed with NEC in a neonatal intensive care unit were staged according to modified Bell's classification, and DECT was performed on patients with NEC stages 2-A, 2-B and 3-A. According to their DECT reports, these patients were then separated into two groups: those with intestinal ischemia and those without intestinal ischemia. The patients with intestinal ischemia were evaluated using surgical reports, and the other patients were evaluated using clinical findings. RESULTS: DECT was performed in 21 patients with NEC stages 2-A, 2-B and 3-A. Twelve patients (57.1%) without ischemia were followed up without surgery. Nine patients (42.9%) with ischemia on DECT were operated on, and resection and anastomosis or ileostomy and colostomy were performed. DISCUSSION: In patients with NEC, DECT significantly increases overall diagnostic confidence in assessing intestinal necrosis when compared with traditional diagnostic methods.

Behaviors and Attitudes of Obstetricians in Turkey Related to Cord Clamping, Cord Milking, and Skin-To-Skin Contact.

Objective This study was planned to evaluate obstetricians' practices of umbilical cord clamping, milking, and skin-to-skin contact applications and to determine the related variables. Material and methods A total of 522 obstetricians participated in the study. Participants were reached via the internet and a 15-item questionnaire was applied about umbilical cord clamping, cord milking, and skin-to-skin contact. Mann-Whitney U test and Student's t-test were used for continuous data and Chi-square test or Fisher's exact test for categorical data in determining the difference between groups. For the multivariate analysis, the possible factors identified with univariate analyses were entered into the logistic regression analysis to determine further independent predictors of delayed clamping. Statistical analysis was performed using the SPSS software (version 20, IBM Corp, Armonk, USA). Results It was determined that 234 (44.8%) of the participants clamped the umbilical cord early whereas 288 (55.2%) clamped it late. It was found that the delayed clamping rates of physicians working in public hospitals were significantly lower than those working in private (p<0.001). It was observed that 132 of the participants (25.3%) did not milk the cord and 180 (34.5%) of them applied it continuously, and no significant difference was found between physicians working in the public and private sectors (p=0.130). It was observed that 384 (73.6%) physicians applied skin-to-skin contact. In the multivariate regression analysis, it was determined that working status in a private hospital with a 3.6 odds ratio (OR) (95% CI = 2.0-6.3) and a low number of patients examined daily with a 1.2 OR (95%CI= 1.0-1.4) were the most important independent factors affecting the choice of delayed clamping. Conclusion It is seen that the most important parameter affecting the birth practices of physicians in our country is the employment status in public or private institutions. The age and professional experience of the physicians who clamp the umbilical cord late were found to be higher. Obstetricians are at the key point in obstetrics practice, and the experience of physicians and the type of institution they work with affect these practices.
