RESUMEN
PURPOSE: Enhanced Recovery After Surgery (ERAS) is a concept that covers evidence-based practices and requires multidisciplinary teamwork, and nurses play a key role in this team. This qualitative research is conducted to describe the experiences of nurses implementing ERAS and the obstacles they encounter in practice. DESIGN: This research was conducted using the phenomenology pattern, one of the qualitative research designs. METHODS: The research study group was determined by criterion sampling, one of the purposeful sampling methods.The criterion for participation in this study is to follow at least one of the steps of the ERAS protocol and volunteer to participate in the study. In this context, 12 nurses who met the inclusion criteria participated in the study. Data were obtained from May 1 to May 31, 2023 using an introductory information form and a semistructured interview form. The introductory information form asked questions such as age, gender, marital status, working year, ERAS application time, and total working year. The semistructured interview form, developed by the authors based on the related literature, consisted of four open-ended questions 1The obtained data were analyzed using the seven-step Colaizzi method. FINDINGS: The study identified three themes: the importance of the ERAS protocol, the obstacles to the ERAS protocol, compliance with the ERAS protocol and applicability. Nine subthemes were found: reducing complications and accelerating the healing process, increasing the level of satisfaction, lack of knowledge, leader confusion, resistance to change, lack of team cooperation, policy, leadership, and education. CONCLUSIONS: This study revealed the experiences of nurses who implement at least one component of ERAS protocols regarding the obstacles to the implementation of the protocol. As a result, nurses stated that lack of information and team cooperation, leader complexity, and resistance to change were obstacles to the protocol. Identifying the obstacles encountered in the implementation of the protocols is important for producing solution suggestions.
RESUMEN
OBJECTIVES: Systemic lupus erythematosus (SLE) is a chronic inflammatory disease characterised by the presence of various autoantibodies. Mild cognitive impairment developing in patients without significant neuropsychiatric (NP) symptoms was thought to be the result of immune-mediated myelinopathy. We aimed to determine the role of myelin oligodendrocyte glycoprotein antibody (MOG-Ab) in the neurological manifestations of childhood-onset SLE (cSLE) and if there is a correlation between various metabolite peaks in magnetic resonance spectroscopy (MRS) and myelinopathy. METHODS: MOG-Ab levels were studied in all healthy subjects (n=28) and in all patients with (NPSLE=9) and without (non-NPSLE=36) overt neuropsychiatric manifestations. Twenty patients (all had a normal-appearing brain on plain magnetic resonance) in non-NPSLE and 20 subjects in healthy group met the MRS imaging standards for evaluation in which normal appearing brain on plain MR. RESULTS: A total of 45 cSLE (36 non-NPSLE and 9 NPSLE) subjects and 28 healthy children were recruited to the study. The mean age of the SLE patients at study time was 16.22±3.22 years. MOG-Ab was not detected in cSLE or in healthy group. There was no significant difference between the non-NPSLE group and healthy subjects in terms of choline, N-acetyl aspartate (NAA), creatine, NAA/creatine, and choline/creatine. CONCLUSIONS: There was no association of MOG-Ab with cSLE, whether NP manifestations were present or not. A causal relationship between immune-mediated myelinopathy and cognitive impairment could not be suggested, since there has been no patient with positive MOG-Ab and there has been no difference in choline, choline/creatine between groups.

Early detection of cognitive developmental delay (CDD) and autism spectrum disorder (ASD) is challenging, despite the numerous scientific studies conducted and different therapeutic strategies. Lack of a biomarker for autism is a limiting factor for early diagnosis, which could provide better outcome with early start of therapy. Because of the high serum fetuin-A concentration during intrauterine life, it has been suggested that fetuin-A may have a role in brain development. The current study sought to determine if fetuin-A, a multifunctional glycoprotein thought to have a role in brain development, may be used as a biomarker for the diagnosis of ASD and developmental delay. The study involved 55 children with cognitive developmental delays and 40 healthy children. Two categories of children with cognitive developmental delays were identified. The participants were subjected to a psychiatric assessment as well as developmental testing. Only 54.5% of the 55 individuals had CDD, whereas 45.5% had ASD. Using an ELISA kit, the levels of serum fetuin-A were determined spectrophotometrically. The serum fetuin-A levels in the patients from the test group were found to be significantly lower than in the healthy individuals (p < 0.001). The cutoff value for the serum fetuin-A levels for cognitive developmental delay and autism spectrum disorder was 518 µg/liter, according to the results of ROC analysis (84.6% sensitivity and 91.4% specificity, AUC: 0.95, p < 0.001). The findings suggest that the serum fetuin-A level may be used to diagnose autism spectrum disorder and cognitive developmental delays.

We aimed to reveal the attitudes and perceptions of a group of nurses toward collaborative work and the barriers to collaborative practice. At the end of the study, we obtained four main themes: leadership in health services, interpersonal interaction factors, cooperation in patient care, standardization. The nurses emphasized the critical elements of respect, relationships and communication as components of effective collaborative practice. As a result, it was stated that the practice of cooperation between doctors and nurses is weak and there are some difficulties and obstacles.
RESUMEN
PURPOSE: This study was conducted to determine the prevalence and severity of postoperative pain in the first 24 hours after surgery and to emphasize the importance of postoperative pain assessment. DESIGN: A descriptive study. METHODS: This study was carried out on May 21, 2019 with 898 patients who had completed the postoperative 24th hour in the surgical clinics of 10 training and research hospitals in Istanbul, the capital of Turkey. Point prevalence was used in the study. Data were collected using a questionnaire developed by the researchers and the Revised American Pain Society Patient Outcome Questionnaire. Descriptive statistics were presented as frequency, percentage, mean, and standard deviation. Nonparametric tests were used for data without normal distribution (Kolmogorov-Smirnov Test, P < .05). Two-group comparisons were performed using the Mann-Whitney U test. The Kruskal Wallis-H test was used for the comparison of three or more groups. Statistical significance was set as P < .05. FINDINGS: The three main types of surgery were general surgery with 31.8%, gynecologic surgery with 12.9%, and orthopedic surgery with 12.7%. The mean lowest level of pain felt by the patients included in the study in the first 24 hours was 3.90 ± 2.94, and the mean highest level of pain was 6.38 ± 4.45. CONCLUSIONS: Postoperative pain is a subjective phenomenon and may be affected by factors such as type of surgery, previous experience of surgery, duration of surgery, the length of the surgical incision, the type of anesthesia, the quality of postoperative care, individual characteristics and experiences, and fear anxiety; thus, the experience of pain may vary from person to person.

Genetic linkage maps are valuable tools for genetic, genomic, and crop breeding studies. Several genetic linkage maps were constructed for the olive (Olea europaea L.) genome, mainly using amplified fragment length polymorphisms (AFLPs) and simple sequence repeat (SSR) markers. However, AFLPs and SSR markers were not enough to develop a high-density olive linkage map. Genotyping-by-sequencing (GBS), a recently developed single-nucleotide polymorphism (SNP) identification methodology based on next-generation sequencing (NGS) technologies, has been demonstrated to be useful for the identification of a high number of SNP markers and the construction of high-density genetic linkage maps. In the present study, we identified a total of 10,941 SNPs from a cross between the olive cultivars 'Gemlik' and 'Edincik Su' using GBS and de novo SNP discovery implemented in the computer program "Stacks." A high-density genetic linkage map for the olive genome was constructed using 121 cross-pollinated full-sib F1 progeny and 5643 markers (21 SSRs, 203 AFLPs, and 5736 SNPs). This linkage map was composed of 25 linkage groups, covering 3049 cM of the olive genome, and the mean distance between the flanking markers was 0.53 cM. To the best of our knowledge, this map is the most saturated genetic linkage map in olive to date. We demonstrated that GBS is a valuable tool for the identification of thousands of SNPs for the construction of a saturated genetic linkage map in olive. The high-density genetic map developed in this study is a useful tool for locating quantitative trait loci and other economically important traits in the olive genome.

BACKGROUND AND OBJECTIVE: Malnutrition and micronutrient deficiencies represent significant concerns in geriatric care, leading to adverse health outcomes in older adults. The study aimed to investigate the prevalence and determinants of micronutrient deficiencies in malnourished older hospitalized patients. DESIGN AND SETTING: This prospective, observational study was conducted in a geriatric acute care unit. PARTICIPANTS: The study included 156 malnourished older adults. MEASUREMENTS: Malnutrition was identified using the Mini Nutritional Assessment-Short Form. Micronutrient status was assessed through serum analysis of vitamins (A, B1, B6, B12, C, D, E, H, K, folic acid) and minerals (iron, zinc, copper, selenium) within 24 h post-admission. RESULTS: The average patient age was 82.3 ± 7.5 years, with 69% female. The results revealed a high prevalence of micronutrient deficiencies, with 90% of patients exhibiting deficiencies in three or more micronutrients. Notably, every patient presented at least one micronutrient deficiency. Common deficiencies were found in vitamins C (75%), D (65%), H (61%), and K (45%), as well as folic acid (37%), iron (31%), zinc (36%) and selenium (35%). In binary regression analysis, the amount of previous weight loss was significantly associated with a higher prevalence of multiple (>2) micronutrient deficiencies (P = 0.045). Other variables such age (P = 0.449), gender (P = 0.252), BMI (P = 0.265) and MNA-SF score (P = 0.200) did not show any significant association with the prevalence multiple micronutrient deficiencies. CONCLUSION: The high prevalence of micronutrient deficiencies in malnourished older hospitalized patients underscore the urgent need for targeted interventions to address micronutrient deficiencies in this population, promoting their health status.

Drug insensitivity is arguably one of the biggest challenges in cancer therapeutics. Although effective therapeutic solutions in cancer are limited due to the emergence of drug insensitivity, exploiting evolutionary understanding in this context can provide potential second-line therapeutics sensitizing the drug insensitive populations. Targeted therapeutic agent dabrafenib is used to treat CRC patients with BRAF V600E genotype and insensitivity to dabrafenib is often observed. Understanding underlying clonal architecture of dabrafenib-induced drug insensitivity and identification of potential second-line therapeutics that could sensitize dabrafenib insensitive populations remain to be elucidated. For this purpose, we utilized cellular barcoding technology to decipher dabrafenib-induced clonal evolution in BRAF V600E mutant HT-29 cells. This approach revealed the detection of both pre-existing and de novo barcodes with increased frequencies as a result of dabrafenib insensitivity. Furthermore, our longitudinal monitoring of drug insensitivity based on barcode detection from floating DNA within used medium enabled to identify temporal dynamics of pre-existing and de novo barcodes in relation to dabrafenib insensitivity in HT-29 cells. Moreover, whole-exome sequencing analysis exhibited possible somatic CNVs and SNVs contributing to dabrafenib insensitivity in HT-29 cells. Last, collateral drug sensitivity testing demonstrated oxaliplatin and capecitabine, alone or in combination, as successful second-like therapeutics in inducing collateral sensitivity in dabrafenib-insensitive HT-29 cells. Overall, our findings demonstrate clonal dynamics of dabrafenib-insensitivity in HT-29 cells. In addition, oxaliplatin and capecitabine, alone or in combination, were successful second-line therapeutics in inducing collateral sensitivity in dabrafenib-insensitive HT-29 cells.

INTRODUCTION: Autism spectrum disorder (ASD) is a neurodevelopmental disorder originating from early childhood. Although there are studies investigating the sense of coherence in caregivers of children with ASD, there is not a previous study in our country. In this study, we aimed to examine the relationship between the sense of coherence and depression levels in mothers of children with ASD. METHOD: Seventy-five mothers of children followed up in rehabilitation centers with the diagnosis of ASD were included in this study. Beck Depression Inventory (BDI) and Sense of Coherence Scale-13 (SOC-13) were administered to mothers. Participants were divided into two groups: a depressive group and a control group according to the BDI cut-off score. SOC-13 total score and sub-scores were compared between these groups. RESULTS: According to the BDI cut-off score, 45 participants (60%) were included in the depressive group. Total SOC-13 score and sub-scores were found to be statistically significantly lower in the depressive group compared with the control group. CONCLUSION: Our study is the first study in our country to examine the relationship between the sense of coherence and depression in mothers of children with ASD. The results showed that there was a significant negative correlation between depression scores and sense of coherence. It is predicted that psychological interventions that will improve the sense of coherence of mothers with children with ASD may play an important role in the treatment of depression, thus leading to an increase in the quality of care provided by parents.
RESUMEN
Introduction: In the pediatric context, most children with autosomal dominant polycystic kidney disease (ADPKD) maintain a normal glomerular filtration rate (GFR) despite underlying structural kidney damage, highlighting the critical need for early intervention and predictive markers. Due to the inverse relationship between kidney volume and kidney function, risk assessments have been presented on the basis of kidney volume. The aim of this study was to use magnetic resonance imaging (MRI)-based kidney volume assessment for risk stratification in pediatric ADPKD and to investigate clinical and genetic differences among risk groups. Methods: This multicenter, cross-sectional, and case-control study included 75 genetically confirmed pediatric ADPKD patients (5-18 years) and 27 controls. Kidney function was assessed by eGFR calculated from serum creatinine and cystatin C using the CKiD-U25 equation. Blood pressure was assessed by both office and 24-hour ambulatory measurements. Kidney volume was calculated from MRI using the stereological method. Total kidney volume was adjusted for the height (htTKV). Patients were stratified from A to E classes according to the Leuven Imaging Classification (LIC) using MRI-derived htTKV. Results: Median (Q1-Q3) age of the patients was 6.0 (2.0-10.0) years, 56% were male. There were no differences in sex, age, height-SDS, or GFR between the patient and control groups. Of the patients, 89% had PKD1 and 11% had PKD2 mutations. Non-missense mutations were 73% in PKD1 and 75% in PKD2. Twenty patients (27%) had hypertension based on ABPM. Median htTKV of the patients was significantly higher than controls (141 vs. 117â ml/m, p = 0.0003). LIC stratification revealed Classes A (38.7%), B (28%), C (24%), and D + E (9.3%). All children in class D + E and 94% in class C had PKD1 variants. Class D + E patients had significantly higher blood pressure values and hypertension compared to other classes (p > 0.05 for all). Discussion: This study distinguishes itself by using MRI-based measurements of kidney volume to stratify pediatric ADPKD patients into specific risk groups. It is important to note that PKD1 mutation and elevated blood pressure were higher in the high-risk groups stratified by age and kidney volume. Our results need to be confirmed in further studies.
RESUMEN
OBJECTIVE: This study aims to compare the effect of thromboembolic prophylaxis in patients diagnosed with hypertensive disorders of pregnancy undergoing cesarean section. METHODS: Three hundred and eighty-six patients were included in the study. The patients were divided into groups according to the type of hypertensive disorders of pregnancy and whether thromboembolism prophylaxis was applied or not. The thromboembolic event incidence and other pregnancy outcomes were compared. RESULTS: Nonadministration of thromboprophylaxis was recorded in 210 patients. Eleven patients had thromboembolic events (5%). Among 176 patients who received thromboprophylaxis, only two patients (1%) had a thromboembolic event (p<0.05). CONCLUSION: There is an increased tendency to thromboembolism in pregnancy. The incidence increases in the presence of hypertension accompanying pregnancy. In our study, the importance of thromboembolism prophylaxis on peri-postnatal complications in patients with hypertensive disorders of pregnancy was emphasized.
RESUMEN
Background: One of the most significant challenges impeding cancer treatment effectiveness is drug resistance. Combining evolutionary understanding with drug resistance can pave the way for the identification of second-line drug options that can overcome drug resistance. Although capecitabine and irinotecan are commonly used therapeutic agents in the treatment of CRC patients, resistance to these agents is common. The underlying clonal dynamics of resistance to these agents using high-resolution barcode technology and identification of effective second-line drugs in this context remain unclear. Methods and materials: Caco-2 and HT-29 cell lines were barcoded, and then capecitabine and irinotecan resistant derivatives of these cell lines were established. The frequencies of barcodes from resistant cell lines and harvested medium, longitudinally, were determined. Collateral drug sensitivity testing was carried out on resistant Caco-2 and HT-29 cell lines using single agents or drug combinations. The SyngeryFinder tool was used to analyse drug combination testing. Results: In Caco-2 and HT-29 cell lines, barcode frequency measurements revealed clonal dynamics of capecitabine and irinotecan formed by both pre-existing and de novo barcodes, indicating the presence of polyclonal drug resistance. The temporal dynamics of clonal evolution in Caco-2 and HT-29 cell lines were demonstrated by longitudinal analysis of pre-existing and de novo barcodes from harvested medium. In Caco-2 and HT-29 cell lines, collateral drug sensitivity revealed a number of drugs that were effective alone and in combination. Conclusion: The use of barcoding technology reveals the clonal dynamics of chemotherapy-induced drug resistance not only from harvested cell populations, but also from longitudinal sampling throughout the course of clonal evolution. Second-line drugs that sensitize drug-resistant CRC cell lines are identified through collateral drug testing.
RESUMEN
Complex evolutionary dynamics governing the drug resistance is one of the major challenges in cancer treatment. Understanding these mechanisms requires a sequencing technology with higher resolution to delineate whether pre-existing or de novo drug mechanisms are behind the drug resistance. Combining this technology with clinically very relevant model system, namely 3D spheroids, better mimicking tumorigenesis and drug resistance have so far been lacking. Thus, we sought to establish dabrafenib and irinotecan resistant derivatives of barcoded 3D spheroids with the ultimate aim to quantify the selection-induced clonal dynamics and identify the genomic determinants in this model system. We found that dabrafenib and irinotecan induced drug resistance in 3D-HT-29 and 3D-HCT-116 spheroids are mediated by pre-existing and de novo resistant barcodes, indicating the presence of polyclonal drug resistance in this system. Moreover, whole-exome sequencing analysis found chromosomal gains and mutations associated with dabrafenib and irinotecan resistance in 3D-HT-29 and 3D-HCT-116 spheroids. Last, we show that dabrafenib and irinotecan resistance are also mediated by multiple drug resistance by detection of upregulation of the drug efflux pumps, ABCB1 and ABCG2, in our spheroid model system. Overall, we present the quantification of drug resistance and evolutionary dynamics in spheroids for the first time using cellular barcoding technology and the underlying genomic determinants of the drug resistance in our model system.

BACKGROUND: Chestnut honey plays a positive role in strengthening the immune system as it contains vitamins, minerals and antioxidants. It, moreover, has both antibacterial and antiviral properties. OBJECTIVES: This study aimed to examine how people consume chestnut honey as a form of traditional medicine and how it might protect them from COVID-19. METHODS: This study was carried out on 177 people (who had been snowball sampled) from a province in Turkey where chestnut honey is widely produced. The data was collected using a 20-open/closed-question online questionnaire form that asked the participants to report their sociodemographic details, how they consume chestnut honey, and about COVID-19. RESULTS: 41.8% of the participants reported that they used chestnut honey to protect themselves against COVID-19, 40.7% believed that chestnut honey helped to make them immune against COVID-19, and 37.3% felt that chestnut honey could treat COVID-19. However, there was no significant relationship between the participants consuming chestnut honey and their either being tested for COVID-19 (p > 0.05, χ2 = 1.080) or testing positive for COVID-19 (p > 0.05, χ2 = 0.793). CONCLUSIONS: This study revealed that chestnut honey is a widely used remedy in Turkey for treating different health problems and for maintaining health. In contrast, it also demonstrated that consuming chestnut honey has no effect on protecting the participants from COVID-19.

OBJECTIVE: Neuron-specific enolase is an established biomarker of neuronal damage. This study aimed to reveal the relationship between serum neuron-specific enolase level and continuous interictal discharges in a group of encephalopathy with electrical status epilepticus in sleep patients for the first time and determine whether there is a neuronal cell loss or damage. MATERIALS AND METHODS: We analyzed serum neuron-specific enolase levels in patients with an electrical status epilepticus in sleep pattern on their electroencephalographs with age- and sex-matched control subjects. Patients with a spike-wave index of at least 50% and acquired neuropsychological regression were included in the study. Magnetic resonance imaging of all electrical status epilepticus in sleep patients and control subjects included in the study was within normal limits. Neuron-specific enolase is measured by the enzyme-linked immunosorbent assay kit based on the sandwich technique. RESULTS: In this study, 14 patients diagnosed with electrical status epilepticus in sleep and 21 healthy controls were included. The median age of electrical status epilepticus in sleep patients was 7.1 years (min-max: 4.5-10.7 years) and 7.7 years (min-max: 3.2-14 years) in the control subjects. According to the results of serum neuron-specific enolase measurements, the mean ± standard deviation level of neuron-specific enolase was 7.61 ± 3.19 ng/dL for the electrical status epilepticus in sleep group and 6.93 ± 2.55 ng/dL for the control group. Serum neuron-specific enolase levels between electrical status epilepticus in sleep patients and the control group were not statistically significant (P = .749). CONCLUSION: No significant difference was observed in serum neuron-specific enolase levels between electrical status epilepticus in sleep patients and control subjects. Our results may indicate that frequent interictal discharges do not result in neuronal cell loss or damage in electrical status epilepticus in sleep patients.
RESUMEN
OBJECTIVE: Cognitive developmental delay is a picture of the group of early-onset chronic diseases that affect 1.5-10% of children. Autism spectrum disorders are neurodevelopmental diseases with a genetic basis and abnormal brain development, characterized by disorders in areas that make up interpersonal relationships, such as communication, social cognition, and processing of emotional signals. Immune system dysfunction is thought to play a role in the pathogenesis of some neurological disorders, including autism. Progranulin is thought to be a regulator of the innate immune response. The purpose of this study was to look at plasma levels of progranulin, an anti-inflammatory neurotrophic factor, in children with autism spectrum disorder and cognitive developmental delay. MATERIALS AND METHODS: The study was conducted on 52 children who were patients and 35 healthy children. Of the 52 children of the patient group, 32 were diagnosed with CDD and 20 were diagnosed with cognitive developmental delay-autism spectrum disorder. Serum progranulin concentrations were measured using a human-specific sandwich enzyme-linked immunosorbent assay. RESULTS: Serum progranulin concentration was statistically lower in the patient group (110.746 ± 26.04) than in the healthy control group (137.346 ± 30.02). There was a statistically significant difference between the groups in levels of serum progranulin (P=.000). Receiver operating characteristic analysis was performed to evaluate the potential of progranulin as a biomarker to distinguish patients with cognitive developmental delay-autism spectrum disorder from healthy children. It detected a moderate area under the curve (0.743 ± 0.06) value and a more significant P value for progranulin (P=.000). CONCLUSION: Progranulin deficiency in patients with autism spectrum disorder-cognitive developmental delay may result in decreased neurotrophic support for many years, with cumulative damage associated with unregulated inflammation that may play a role in autism spectrum disorder-cognitive developmental delay. We believe that low progranulin levels could be a biomarker for autism spectrum disorder-cognitive developmental delay.
RESUMEN
PURPOSE: In patients diagnosed with epilepsy, decreased ratio of N-acetyl aspartate to creatine (NAA/Cr) measured in magnetic resonance spectroscopy (MRS) has been accepted as a sign of neuronal cell loss or dysfunction. In this study, we aimed to determine whether a similar neuronal cell loss is present in a group of encephalopathy with electrical status epilepticus in sleep (ESES) patients METHODS: We performed this case-control study at a tertiary pediatric neurology center with patients with ESES. Inclusion criteria for the patient group were as follows: 1) a spike-wave index of at least 50%, 2) acquired neuropsychological regression, 3) normal cranial MRI. Eventually, a total of 21 patients with ESES and 17 control subjects were enrolled in the study. MRI of all control subjects was also within normal limits. 3D Slicer program was used for the analysis of thalamic and brain volumes. LCModel spectral fitting software was used to analyze single-voxel MRS data from the right and left thalamus of the subjects. RESULTS: The mean age was 8.0 ± 1.88 years and 8.3 ± 1.70 years in ESES patients and the control subjects. After correcting for the main potential confounders (age and gender) with a linear regression model, NAA/Creatine ratio of the right thalamus was significantly lower in the ESES patient group compared to the healthy control group (p = 0.026). Likewise, the left thalamus NAA/Cr ratio was significantly lower in the ESES patient group than the healthy control group (p = 0.007). After correcting for age and gender, right thalamic volume was not statistically significantly smaller in ESES patients than in healthy controls (p = 0.337), but left thalamic volume was smaller in ESES patients than in healthy controls (p = 0.024). CONCLUSION: In ESES patients, the NAA/Creatine ratio, which is an indicator of neuronal cell loss or dysfunction in the right and left thalamus, which appears regular on MRI, was found to be significantly lower than the healthy control group. This metabolic-induced thalamic dysfunction, which was reported for the first time up to date, may play a role in ESES epileptogenesis.

Long bone fractures are rarely seen in newborns. Though the femoral bone is more fragile, occasionally the humeral bone may fracture. Presently described is a rare case of a humeral fracture occurring at birth. A female infant born by vaginal delivery to a 35-year-old multipara woman at the 40th gestational week was hypotonic and in respiratory distress. Resuscitation was performed for 15 minutes. Bilateral Moro reflexes could not be elicited. Radiological evaluation revealed a left humeral diaphysis fracture. Humeral fractures are generally associated with the increase in cesarean deliveries; however, a newborn may also experience trauma during difficult labor and vaginal delivery. Pregnant women should be informed about the potential occurrence of long bone fractures, particularly as a result of necessary obstetric maneuvers performed during a breech delivery. In addition, it should be emphasized that cesarean delivery does not completely eliminate the risk of trauma to the infant.
