ABSTRACT
Background Natural language processing models are increasingly used in scientific research, and their ability to perform various tasks in the research process is rapidly advancing. This study aims to investigate whether Generative Pre-trained Transformer 4 (GPT-4) is equal to humans in writing introduction sections for scientific articles. Methods This randomized non-inferiority study was reported according to the Consolidated Standards of Reporting Trials for non-inferiority trials and artificial intelligence (AI) guidelines. GPT-4 was instructed to synthesize 18 introduction sections based on the aim of previously published studies, and these sections were compared to the human-written introductions already published in a medical journal. Eight blinded assessors randomly evaluated the introduction sections using 1-10 Likert scales. Results There was no significant difference between GPT-4 and human introductions regarding publishability and content quality. GPT-4 had one point significantly better scores in readability, which was considered a non-relevant difference. The majority of assessors (59%) preferred GPT-4, while 33% preferred human-written introductions. Based on Lix and Flesch-Kincaid scores, GPT-4 introductions were 10 and two points higher, respectively, indicating that the sentences were longer and had longer words. Conclusion GPT-4 was found to be equal to humans in writing introductions regarding publishability, readability, and content quality. The majority of assessors preferred GPT-4 introductions and less than half could determine which were written by GPT-4 or humans. These findings suggest that GPT-4 can be a useful tool for writing introduction sections, and further studies should evaluate its ability to write other parts of scientific articles.
ABSTRACT
Study objective: The lockdown imposed on children due to the COVID-19 pandemic and their inability to attend school increased their exposure to indoor allergens by causing them to spend more time indoors. In this study, the aim was to reveal the effect of the pandemic and increased exposure to indoor aeroallergens on the symptom severity of school-age children with house dust mite-sensitized allergic rhinitis (AR). Patients and methods: Patients between the ages of 6-18-years old, who were followed-up with the diagnosis of perennial AR sensitized to only mites were questioned about their sinonasal symptoms. The Total Nasal Symptom Score (TNSS) questionnaire was performed. The clinical findings, drug usage, frequency of infections and attacks were evaluated and compared during COVID-19 lockdown and the same time frame in 2019. Results: Sixty-five patients had AR, and 33 patients (50.8%) had AR with asthma. TNSS of the patients improved during the pandemic (P < 0.001) and their medication scores decreased significantly (P < 0.001). The frequency of respiratory tract infections and asthma attacks decreased significantly (P < 0.001). In multivariate analysis, risk factors were evaluated for the 'group with worsening TNSS' and coal/wood burning was detected to be an independent risk factor (P = 0.006; OR = 10.09 (95% CI: 1.97-51.87)). Conclusion: Although the increased stay at home, it is surprising that nasal symptoms improved in our patients. This result suggests that whereas allergen sensitivity is responsible for the pathogenesis of AR, exposure to pollution and viral infections which are reduced by masking and social distance may also play an important role in the pathogenesis.
Introduction: Le confinement imposé aux enfants en raison de la pandémie de COVID-19, l'impossibilité pour les enfants d'aller à l'école; ont augmenté leur exposition aux allergènes intérieurs en les obligeant à passer plus de temps à l'intérieur. Dans cette étude, il visait à révéler l'effet de la période pandémique et de l'exposition accrue aux aéroallergènes intérieurs sur la sévérité des symptômes des enfants d'âge scolaire atteints de rhinite allergique (RA) sensibilisée aux acariens. Méthode: Patients âgés de 6 à 18 ans, qui ont été suivis avec le diagnostic de RA perannuelle avec seulement des acariens sensibilisés; ont été interrogés sur leurs symptômes naso-sinusiens. Le questionnaire Total Nasal Symptom Score (TNSS) a été réalisé. Leurs résultats cliniques, l'utilisation de médicaments, la fréquence des infections et des attaques ont été évalués et comparés pendant le verrouillage de COVID-19 et la même période de 2019. Résultats: Soixante-cinq patients avaient une RA et 33 patients (50,8 %) avaient une RA avec asthme. Le TNSS des patients pendant la période pandémique s'est amélioré (p < 0,001) et leurs scores de médication ont diminué de manière significative (p < 0,001). La fréquence des infections des voies respiratoires et des crises d'asthme a diminué significativement (p < 0,001). En analyse multivariée, les facteurs de risque ont été évalués pour le « groupe d'aggravation du TNSS ¼, la combustion de charbon/bois a été détectée comme étant un facteur de risque indépendant (p = 0,006 ; OR = 10,09 (IC95 % : 1,9751,87)). Conclusion: Malgré l'augmentation du séjour à domicile, il est surprenant que les symptômes nasaux de nos patients se soient améliorés. Ce résultat suggère que si la sensibilité aux allergènes est responsable de la pathogenèse de la RA, l'exposition à la pollution et aux infections virales qui sont réduites par le masque et la distance sociale peuvent également jouer un rôle important dans la pathogenèse.
ABSTRACT
BACKGROUND: The aims of this study were to describe the etiologies of acute headache presenting to the pediatric emergency department, determine their clinical characteristics, the prevalence of red flag findings and neuroimaging and identify predictors of headaches because of serious intracranial diseases. MATERIALS AND METHODS: Patients from 2 to 18 years of age who visited pediatric emergency department with a chief complaint of headache between January 1, 2016 and August 31, 2020 were retrospectively evaluated. RESULTS: The mean age of the 558 patients included in the study was 11.17±3.78 years, and 290 (52%) were female. The most common cause of acute headache was head and neck area infections (except central nervous system infections) in 355 (63.6%) patients. Forty patients (7.2%) had a headache because of serious intracranial diseases. According to binary logistic regression analysis, the findings that predicted a serious intracranial diseases were abnormal neurological physical examination [odds ratio (OR): 187.57; 95% confidence interval (CI): 32.67-1076.64], recent onset or suddenly severe headache (OR: 14.41; 95% CI: 3.14-65.91), and vomiting (OR: 9.42; 95% CI: 1.90-46.63). Neuroimaging was performed in 63 (11.3%) patients, and 7 (1.25%) had a pathology requiring emergency treatment. CONCLUSIONS: The majority of acute headaches were evaluated as secondary headache. The most common cause of acute headache was head and neck area infections. Abnormal neurological physical examination, recent onset or suddenly severe headache, and vomiting were the most useful red flags for predicting serious intracranial diseases. The requirement for neuroimaging should be evaluated individually for each patient.

PURPOSE: Factors affecting local outcome were evaluated in patients with clinically node-positive (cN+) breast cancer at diagnosis, who underwent sentinel lymph node biopsy (SLNB) alone after neoadjuvant chemotherapy (NAC). METHODS: Between 2004 and 2018, 303 cytopathology-proven cN (+) patients in a multicentric registry, who received NAC and underwent SLNB alone were analysed. All patients had regional nodal irradiation. RESULTS: Median age was 46 (23-70). Of those, 211 patients had ypN0 disease (69.6%), whereas 92 patients had ypN (+) disease including 19 (20.6%) isolated tumor cells (ITC), 33 micrometastases (35.9%) and 40 macrometastases (43.5%). At a median follow-up of 36 months (24-172), one patient (0.3%) with macrometastatic SLN was found to have locoregional recurrence as chest wall and supraclavicular LN metastases at the 60th month. Five-year disease-free survival (DFS) and disease specific survival (DSS) rates were 87% and 95%, respectively. Patients with cT3/4 (HR = 2.41, 95% CI; 1.14-5.07), non-luminal molecular pathology (HR = 2.60, 95% CI, 1.16-5.82), and non-pCR in the breast (HR = 2.11, 95% CI, 0.89-5.01) were found to have an increased HR compared to others in 5-year DFS. However, no difference could be found between ypN0 and ypN ITC and micrometastasis (HR = 1.23, 95% CI, 0.44-3.47), whereas there was a slight increase in HR of patients with ypN macrometastasis versus ypN0 (HR = 1.91, 95% CI, 0.63-5.79). CONCLUSION: ALND could be avoided in meticulously selected cN (+) patients who underwent SLNB after NAC having breast and/or nodal pCR, cT1-2, or low volume residual nodal disease with luminal pathology, as long as axillary radiotherapy is provided.

INTRODUCTION AND OBJECTIVES: Asthma may have a detrimental effect on school attendance and achievement. Friend relations, attendance to school activities, quality of life (QOL) of asthmatic children may be negatively affected. The aim of this study was to evaluate factors influencing school functioning for asthmatic school-age children. MATERIALS AND METHODS: From January to May 2019, parents and school-age children who were followed by a diagnosis of asthma for more than one year, from seven pediatric allergy centers, were given a standard questionnaire including questions about child's disease, school performance, absenteeism, home-family-school conditions. A pediatric QOL questionnaire was filled out by children. For evaluating control in the previous year, children who had more than two exacerbations and/or had any exacerbations needing systemic corticosteroids in the previous year were defined as inadequate control. School absence over nine days was taken into account as this has been shown to bring a risk for successful school life. RESULTS: 507 patients were included. Asthma control status was found to be effective on school absence (p < 0.001), on school success (especially math scores) (p < 0.001), on friend relations (p = 0.033), QOL (p < 0.001), attendance to school activities (p < 0.001). Regular follow-up (p < 0.001), regular use of asthma medication (p = 0.014), tobacco smoke exposure (p < 0.001), heating with stove at home (p = 0.01) affected asthma control. School conditions such as crowdedness (p = 0.044), humidity of the class (p = 0.025), knowledge of teacher about child's asthma (p = 0.012) were effective on asthma control independent of home conditions and asthma treatment parameters. CONCLUSION: School interventions are important to improve asthma management

BACKGROUND: Drug allergies are reactions within the context of drug hypersensitivity reactions, which are caused by immunological mechanisms due to a previously sensitising drug. Beta-lactam antibiotics (BLA) are the leading agents causing drug hypersensitivity reactions in children. The aim of this study is to evaluate the diagnostic importance of in vivo and in vitro diagnostic tests in children with suspected immediate-type BLA hypersensitivity and to investigate the frequency of their use for the final diagnosis. METHODS: Patients admitted to the Outpatient Clinic of Division of Paediatric Allergy and Immunology with suspicion of immediate-type BLA hypersensitivity between December 2014 and December 2018 were investigated. Patients with a history of immediate reactions to BLA were examined by performing drug specific IgE, skin prick tests, intradermal tests and drug provocation tests (DPT). RESULTS: During the study period, 148 patients were admitted to our clinic with suspected immediate-type BLA hypersensitivity. Forty-eight patients completed all assessment steps and were enrolled in the study. It has been shown that 27 patients did not have drug allergy. BLA hypersensitivity was proven in 21 patients by using in vivo test algorithm. More than half of the patients were diagnosed via skin tests with culprit drug. CONCLUSION: Allergy work-up should be performed in patients with immediate reactions to BLA. A skin test can demonstrate BLA hypersensitivity in most patients. Thus, skin tests should be performed prior to the drug provocation test

Background: The presence of atopy is considered as a risk factor for severe respiratory symptoms in children. The objective of this study was to examine the effect of atopy on the course of disease in children hospitalised with viral pneumonia. Methods: Children between the ages of 1 and 6 years hospitalised due to viral pneumonia between the years of 2013 and 2016 were included to this multicentre study. Patients were classified into two groups as mild-moderate and severe according to the course of pneumonia. Presence of atopy was evaluated with skin prick tests. Groups were compared to evaluate the risk factors associated with severe viral pneumonia. Results: A total of 280 patients from nine centres were included in the study. Of these patients, 163 (58.2%) were male. Respiratory syncytial virus (29.7%), Influenza A (20.5%), rhinovirus (18.9%), adenovirus (10%), human metapneumovirus (8%), parainfluenza (5.2%), coronavirus (6%), and bocavirus (1.6%) were isolated from respiratory samples. Eighty-five (30.4%) children had severe pneumonia. Atopic sensitisation was found in 21.4% of the patients. Ever wheezing (RR: 1.6, 95% CI: 1.1-2.4), parental asthma (RR: 1.5, 95% CI: 1.1-2.2), other allergic diseases in the family (RR: 1.8, 95% CI: 1.2-2.9) and environmental tobacco smoke (RR: 1.6, 95% CI: 1.1-3.5) were more common in the severe pneumonia group. Conclusions: When patients with mild-moderate pneumonia were compared to patients with severe pneumonia, frequency of atopy was not different between the two groups. However, parental asthma, ever wheezing and environmental tobacco smoke exposure are risk factors for severe viral pneumonia in children (AU)

Background: The diagnostic values for the skin prick test (SPT) diameters and egg white-specific IgE (EW-sIgE) levels that will allow us to predict the result of the oral food challenge test (OFC) in the diagnosis of egg white allergy vary by the community where the study is carried out. Objective: This study aimed to determine the diagnostic values of SPT and EW-sIgE levels in the diagnosis of egg white allergy. Methods: 59 patients followed with the diagnosis of egg allergy September 2013 to September 2015 were included in our retrospective cross-sectional study. The patients were investigated in terms of egg and anaphylaxis history or the requirement of the OFC positivity. The demographic, clinical and laboratory findings of the cases were recorded, and they were compared with the patients with the suspected egg allergy but negative OFC (n = 47). Results: In the study, for all age groups, the value of 5mm in SPT was found to be significant at 96.4% positive predictive value (PPV) and 97.8% specificity and the value of 5.27kU/L for EW-sIgE was found to be significant at 76% PPV and 86.6% specificity for egg white. The diagnostic power of the SPT for egg white (AUC: 72.2%) was determined to be significantly higher compared to the diagnostic power of the EW-sIgE (AUC: 52.3%) (p < 0.05). Conclusion: Along with the determination of the diagnostic values of communities, the rapid and accurate diagnosis of the children with a food allergy will be ensured, and the patient follow-up will be made easier (AU)

BACKGROUND: Food protein-induced allergic proctocolitis (FPIAP) is characterised by inflammation of the distal colon in response to one or more food proteins. It is a benign condition of bloody stools in a well-appearing infant, with usual onset between one and four weeks of age. OBJECTIVE: Our objective was to examine the clinical properties of patients with FPIAP, tolerance development time as well as the risk factors that affect tolerance development. METHODS: The clinical symptoms, offending factors, laboratory findings, methods used in the diagnosis and tolerance development for 77 patients followed in the Paediatric Allergy and Gastroenterology Clinics with the diagnosis of FPIAP during January 2010-January 2015 were examined in our retrospective cross-sectional study. RESULTS: The starting age of the symptoms was 3.3±4.7 months (0-36). Milk was found as the offending substance for 78% of the patients, milk and egg for 13% and egg for 5%. Mean tolerance development time of the patients was 14.7±11.9 months (3-66 months). Tolerance developed before the age of one year in 40% of the patients. Tolerance developed between the age of 1-2 years in 27%, between the age of 2-3 years in 9% and after the age of 3 years in 5% of the patients. CONCLUSIONS: Smaller onset age and onset of symptoms during breastfeeding were found associated with early tolerance development. In the majority of the patients, FPIAP resolves before the age of one year, however in some of the patients this duration may be much longer

OBJECTIVE: The purpose of this prospective study was to examine the temperament dimensions of the patients with boxer fracture and compare them with age- and sex-matched controls. METHODS: We performed a prospective analysis investigating affective temperaments of the 102 patients with boxer fractures and compared them with 100 sex- and age-matched controls that were referred to the emergency department due to incidental soft-tissue trauma. Affective temperament of the patients was evaluated by Memphis, Pisa, Paris, and San Diego-Auto questionnaire (TEMPS-A). Both incidences of dominant affective temperaments of boxer fracture cases with previously validated normal Turkish population and controls and differences between mean values of temperament scores were analyzed. RESULTS: The mean age of the patients with boxer fractures was 25.6 (range 17-47) and 27.7 years (range 17-49) for controls. We found that dominant irritable temperament (n = 10; 9.7%) had significantly higher incidence from both control group and normal Turkish population (p < 0.001). In addition, there was significant difference between anxious temperament scores of two groups (p = 0.013). CONCLUSION: The understanding of mood of patients with boxer fractures will help us to enhance treatment plan and may prevent further intentional injuries by providing an insight into better controlling physical health of the patients.

Background: Prospective cohort studies have provided useful knowledge about the natural history of asthma. However, most of the studies are conducted in western countries but the course of the disease and long-term outcomes may differ between countries due to environmental and cultural factors. Objective: The aim of this study is to describe the long-term outcomes of childhood asthma, with data from a follow-up study of at least 10 years, in western Anatolia, Turkey. Methods: Fifty-two patients diagnosed with persistent allergic asthma participated in the study. The patient's demographics, findings on admission, age at onset of disease, time of diagnosis, history of other allergic conditions, history of parental asthma and allergic disorders, presence of pharmacotherapy and immunotherapy were obtained from patients records. The factors influencing remission at the end of 10 years follow-up were evaluated. Results: A total of 20 patients (38.5%) were on remission at the end of 10 years. The type of allergen, multi-allergen sensitivity, eosinophilia and elevated serum immunoglobulin E on admission, accompanying allergic disorders and atopy in parents, and allergen immunotherapy did not affect the remission rate (p > 0.05). Conclusion: Childhood persistent asthma is not a homogeneous clinical entity but high clinical remission rates are obtained in western Anatolia. There is no significant predictor of clinical remission in long term follow-up. Prospective studies should be performed in larger asthmatic populations to obtain further data about the natural course of childhood asthma (AU)

Objective: We aimed to establish the characteristics of anaphylaxis in childhood. Methods: Forty-four patients who had experienced anaphylaxis in a period of 10 years (from 1999 to 2009), were included in the study. Parameters analysed were age, gender, concomitant allergic disease, trigger, setting, clinical symptoms, treatment, prognosis and prophylaxis. Results: The total numbers of anaphylaxis cases were 44 in a ten-year period. The ages of patients ranged from 3 to 14 years (11.50 ± 3.87 years) and the majority were male. 33 of the patients (75%) had a concomitant allergic disease. The trigger was determined in 93.2% of the cases, being most frequent: food (27.3%), and SIT (25%), followed by bee sting, medications and others. Respiratory (95.5%), dermatological (90.9%), cardiovascular (20.5%), neuropsychiatric (25%), and gastrointestinal (11.4%) symptoms were seen most frequently. For anaphylaxis triggered by food, the duration of anaphylactic episode was significantly longer (p < 0.05). No biphasic reaction was observed during these attacks. Of our patients, only one developed respiratory failure and cardiac arrest due to SIT, and intensive care support was required. Discussion: As a trigger for anaphylaxis, the frequency of SIT is so high that it cannot be described by the study group including patients who were followed up in an outpatient allergy clinic (AU)

OBJECTIVE: We aimed to establish the characteristics of anaphylaxis in childhood. METHODS: Forty-four patients who had experienced anaphylaxis in a period of 10 years (from 1999 to 2009), were included in the study. Parameters analysed were age, gender, concomitant allergic disease, trigger, setting, clinical symptoms, treatment, prognosis and prophylaxis. RESULTS: The total numbers of anaphylaxis cases were 44 in a ten-year period. The ages of patients ranged from 3 to 14 years (11.50 ± 3.87 years) and the majority were male. 33 of the patients (75%) had a concomitant allergic disease. The trigger was determined in 93.2% of the cases, being most frequent: food (27.3%), and SIT (25%), followed by bee sting, medications and others.

BACKGROUND: Prospective cohort studies have provided useful knowledge about the natural history of asthma. However, most of the studies are conducted in western countries but the course of the disease and long-term outcomes may differ between countries due to environmental and cultural factors. OBJECTIVE: The aim of this study is to describe the long-term outcomes of childhood asthma, with data from a follow-up study of at least 10 years, in western Anatolia, Turkey. METHODS: Fifty-two patients diagnosed with persistent allergic asthma participated in the study. The patient's demographics, findings on admission, age at onset of disease, time of diagnosis, history of other allergic conditions, history of parental asthma and allergic disorders, presence of pharmacotherapy and immunotherapy were obtained from patients' records. The factors influencing remission at the end of 10 years follow-up were evaluated. RESULTS: A total of 20 patients (38.5%) were on remission at the end of 10 years. The type of allergen, multi-allergen sensitivity, eosinophilia and elevated serum immunoglobulin E on admission, accompanying allergic disorders and atopy in parents, and allergen immunotherapy did not affect the remission rate (p>0.05). CONCLUSION: Childhood persistent asthma is not a homogeneous clinical entity but high clinical remission rates are obtained in western Anatolia. There is no significant predictor of clinical remission in long term follow-up. Prospective studies should be performed in larger asthmatic populations to obtain further data about the natural course of childhood asthma.

The discovery of 1,3,8-triazaspiro[4.5]decane-2,4-diones (spirohydantoins) as a structural class of pan-inhibitors of the prolyl hydroxylase (PHD) family of enzymes for the treatment of anemia is described. The initial hit class, spirooxindoles, was identified through affinity selection mass spectrometry (AS-MS) and optimized for PHD2 inhibition and optimal PK/PD profile (short-acting PHDi inhibitors). 1,3,8-Triazaspiro[4.5]decane-2,4-diones (spirohydantoins) were optimized as an advanced lead class derived from the original spiroindole hit. A new set of general conditions for C-N coupling, developed using a high-throughput experimentation (HTE) technique, enabled a full SAR analysis of the spirohydantoins. This rapid and directed SAR exploration has resulted in the first reported examples of hydantoin derivatives with good PK in preclinical species. Potassium channel off-target activity (hERG) was successfully eliminated through the systematic introduction of acidic functionality to the molecular structure. Undesired upregulation of alanine aminotransferese (ALT) liver enzymes was mitigated and a robust on-/off-target margin was achieved. Spirohydantoins represent a class of highly efficacious, short-acting PHD1-3 inhibitors causing a robust erythropoietin (EPO) upregulation in vivo in multiple preclinical species. This profile deems spirohydantoins as attractive short-acting PHDi inhibitors with the potential for treatment of anemia.
