Our Treatment Experience in Poisoning With Calcium Channel Blockers: A Series of Twelve Cases
Full text linkBackground: Intoxications with cardiovascular system drugs constitute a small percentage of all poisoning cases. Calcium Channel Blockers (CCBs) are the most common drug poisoning in this group. Objectives: We aimed to evaluate the effectiveness of treatments for CCB poisoning and add to the current body of literature by outlining the clinical treatments we employ for bradyarrhythmia, hypotension, and resistant vasodilation resulting from CCB poisoning, as well as sharing our clinical insights in this field. Methods: Twelve patients, ranging in age from 1 month to 18 years, were admitted to the Tertiary Paediatric Intensive Care Unit (PICU) for treatment of medication poisoning related to the CCB group. Patients who ingested several drugs that caused CCB were not allowed to participate in the trial. Results: Twelve patients were followed up in the PICU due to poisoning with CCB group drugs. Of the patients, 7 were male and 5 were female. Five of the patients had taken CCB medication with the purpose of committing suicide, and 7 of them accidentally. All of the patients who received CCB to commit suicide had taken verapamil. Five patients whose hypotension and bradycardia continued were administered inotropes. In addition to PI, calcium gluconate, intravenous lipid, glucagon, insulin, bicarbonate, and methylene blue were given as therapy to our symptomatic patients. Plasmapheresis was applied to a patient who was hospitalized in the PICU due to a sudden loss of consciousness. Conclusions: In the management of patients with CCB poisoning, the use of hyperinsulinemia euglycemia, intravenous lipid emulsion treatment, glucagon treatments, and treatments including methylene blue and extracorporeal life support should be considered in cases of resistant hypotension, bradycardia, and coma in the early period

Corrosion behavior of mild steel in 1 M HCl with Cyclotrichium niveum as a green inhibitor
No full textRecently, green inhibitors are replacing classical inhibitors in the acid cleaning industry due to very low cost, environmentally friendly and none toxic. In this study, Cyclotrichium niveum is used as a potential green corrosion inhibitor to investigate the corrosion behavior of mild steel (MS) in chloride solution using electrochemical, morphological, structural and quantum chemical methods. Fifty-three flavonoids are detected in methanol extract of cyclotrichium niveum by LC/ESI-MS/MS. While icorr values decreased, Rp and inhibition efficiencies values derived from electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) increased in increasing inhibitor concentrations. Maximum inhibition efficiency is found to be 97.3%, that is the almost highest value, when compared to previous studies and plant extract is classified as a mixed type inhibitor with respect to the potentiodynamic polarization (PDP). The model that best fits the experimental values is the Langmuir isotherm. The temperature effect is also studied in the range of 25–55 ○C. Higher activation energy is obtained in the presence of inhibitor, suggesting that it acts as an efficient inhibitor by forming a physical barrier to the charge and mass transfer reaction, leading to reduction in corrosion rate. Scanning electron and atomic force microscopies showed the more uniform, crack and pits free structure, confirming that there is a protective film over the MS surface for inhibited solution. XPS analysis showed the existence of C, O, and Fe atoms on the MS surface. Quantum chemical calculation manifested the adsorption mechanism associated with the electronic structure of the molecules. The findings of this work can be applicable in chemical cleaning process with acid treatment.English Institute of Spor
Can deep learning replace histopathological examinations in the differential diagnosis of cervical lymphadenopathy?
No full textIntroduction: We aimed to develop a diagnostic deep learning model using contrast-enhanced CT images and to investigate whether cervical lymphadenopathies can be diagnosed with these deep learning methods without radiologist interpretations and histopathological examinations.
Material method: A total of 400 patients who underwent surgery for lymphadenopathy in the neck between 2010 and 2022 were retrospectively analyzed. They were examined in four groups of 100 patients: the granulomatous diseases group, the lymphoma group, the squamous cell tumor group, and the reactive hyperplasia group. The diagnoses of the patients were confirmed histopathologically. Two CT images from all the patients in each group were used in the study. The CT images were classified using ResNet50, NASNetMobile, and DenseNet121 architecture input.
Results: The classification accuracies obtained with ResNet50, DenseNet121, and NASNetMobile were 92.5%, 90.62, and 87.5, respectively.
Conclusion: Deep learning is a useful diagnostic tool in diagnosing cervical lymphadenopathy. In the near future, many diseases could be diagnosed with deep learning models without radiologist interpretations and invasive examinations such as histopathological examinations. However, further studies with much larger case series are needed to develop accurate deep-learning models

Sosyal Hizmet Öğrencilerinin Yoksulluğa İlişkin Tutumlarının İncelenmesi
No full textYoksulluk çağımızın önemli sorunlarındandır. Çok boyutlu yapısı nedeniyle farklı değişkenler temel alınarak açıklanmakta ve ölçümü için çeşitli yöntemler geliştirilmektedir. Sosyal çalışmacılar yoksul müracaatçılara yönelik çalışmalarıyla yoksullukla mücadeleye katkı sunmaktadır. Ancak yoksulluğun nedenleri hakkında yapılan araştırmaların eksikliği ve sosyal hizmet öğrencilerinin yoksullukla ilgili tutumlarının belirlenmemesi, gelecekteki mücadele çabalarını önemli oranda etkilemektedir. Dolayısıyla araştırmanın amacı sosyal hizmet öğrencilerinin yoksulluğun nedenlerine yönelik tutumlarını incelemektir. Araştırma, Türkiye'de sosyal hizmet lisans eğitimi alan öğrencilerle yürütülmüştür. Araştırmanın örneklemini 25.10.2022 tarihinde Yükseköğretim Bilgi Sistemi (YÖKSİS) verileri kullanılarak Ankara ve Eskişehir illerindeki üniversitelerde okuyan 232 öğrenci oluşturmuştur. Araştırmada sosyo-demografik özelliklere dair "Kişisel Bilgi Formu" ile "Yoksulluğa İlişkin Nedensel Atıflar Ölçeği" kullanılmıştır. Araştırmada, öğrencilerin yoksulluğun nedenlerine yönelik algılarının çoğunlukla yapısal düzeyde ve yoksullara yönelik sosyal hizmet uygulamalarının hak temelli yürütülmesi gerektiği düşüncesinin yaygın olduğu görülmüştür. Katılımcıların gelir düzeyi arttıkça yapısal atıf yapma düzeylerinin azaldığı, kadınların erkeklere göre yoksulluğun nedenlerine daha fazla yapısal atıfta bulunduğu, dünya görüşlerine göre yapısal atıf yapma eğilimlerinin değiştiği belirlenmiştir. Sosyal hizmet mesleğinin yoksulluğun önlenmesinde önemli konumda olduğuna ve sosyal yardımların arttırılması gerektiği görüşüne katılan katılımcıların, yapısal atıf düzeylerinin ağırlıklı olduğu saptanmıştır. Sosyal çalışmacılar, insan hakları temelli yaklaşımla müdahalelerini gerçekleştirmelidir. Dolayısıyla düşünce, tutum ve davranış düzeyinde yoksulluğa ilişkin yaklaşımları bilmek yoksullukla etkili mücadele açısından büyük önem taşımaktadır
Electrochemical behavior of Pt nano-particles dispersed on Cu/Ni electrode in alkaline environment
Full text linkThe development of a low-cost Pt-based electrocatalyst for industrial water splitting is important. In this study, to prepare cost-efficient Pt-based electrocatalyst for hydrogen evolution, Cu electrode is deposited with nickel (Cu/Ni) and this surface is modified with Pt nanoparticles by electrodeposition method (Cu/Ni–Pt). The surface properties of the produced electrocatalysts are studied via X-ray diffraction (XRD), scanning electron spectroscopy (SEM), energy dispersive X-ray analysis (EDX), transmission electron microscopy (TEM) and atomic force microscopy (AFM). Characterizations demonstrated that the coating is homogeneous and compact. Hydrogen evolution and corrosion behaviors of prepared electrode (Cu/Ni–Pt) are examined in 1.0 M KOH solution using cyclic voltammetry (CV) and cathodic and anodic current-potential curves, electrochemical impedance spectroscopy (EIS). Tafel slope is determined to be 133 mV dec−1 on Cu/Ni–Pt. Very high exchange current density (5.65 mA cm−2) and very low charge transfer resistance (0.91 Ω cm2 at 1.05 V vs RHE) are measured again on this electrocatalyst. High activity is due to intrinsic activity of Pt and synergistic interaction of Pt and Ni. Besides, Cu/Ni–Pt exhibits so stable structure over 4 h without any current densities decay as well as showing good corrosion performance after long-term immersion times and these properties make it possible electrocatalyst with high corrosion resistant and activity in the water electrolysis systems

Turist Rehberlerinin Karşılaştıkları İş Kazaları ve Meslek Hastalıkları
Full text linkTurist rehberliği mesleği, çalışma koşulları nedeniyle iş kazaları ve meslek hastalıkları konusunda birçok riski bünyesinde barındırmaktadır. Uzun çalışma saatleri, uzun süren seyahatler, yoğun çalışma temposu, uykusuzluk ve fiziksel ve zihinsel yorgunluk gibi faktörler meslekte iş kazalarının ve meslek hastalıklarının yaşanmasına neden olmaktadır. Turist rehberlerinin meslekte karşılaştıkları iş kazaları ve meslek hastalıklarının belirlenmesi ve bu konuda mevcut durumun ortaya konulması, mesleğin icrasında turist rehberlerine yol gösterici olması ve bu hususta gerekli önlemleri almaları noktasında onlara yardımcı olması açısından önem arz etmektedir. Bu bağlamda bu çalışmada, turist rehberlerinin yaşadıkları iş kazaları ve meslek hastalıklarının belirlenmesi ve bunlara yönelik alınabilecek önlemlerin ve konuya ilişkin tavsiyelerin tespit edilmesi amaçlanmaktadır. Bu amaç doğrultusunda, mevcut durumun tespit edilebilmesi için nitel veri toplama tekniği tercih edilerek yarı yapılandırılmış görüşme formu oluşturulmuştur. Elde edilen veriler tematik analiz ile değerlendirilerek önce kodlanmış, ardından belirli temalar altında kategorize edilmiştir. Araştırma sonucunda, turist rehberlerinin en fazla karşılaştıkları iş kazalarının “trafik kazası” ve “ayak/bilek burkulmaları” olduğu; yaşanılan iş kazalarının çoğunlukla “ören yerlerinde” ve “tur araçlarında” gerçekleştiği ve iş kazalarının gerçekleşme sebebinin ise “ören yeri arazi şartları”, “ikinci şahıs hatası” ve “kişisel ihmaller” gibi faktörlerden kaynaklı olduğu belirlenmiştir. Turist rehberlerinin yaşadıkları meslek hastalıkları içerisinde en sık tekrarlananların “ses kısıklığı”, “psikolojik yıpranmalar”, “boğaz ağrısı” ve “bel ağrısı” olduğu tespit edilmiştir. Söz konusu hastalıkların yaşanma sebeplerinin ise “kalabalık gruplara gün içinde yüksek sesle hitap etmek”, “fiziksel olarak efor sarf etmek” ve “yoğun çalışma temposu ve stres” kaynaklı olduğu belirlenmiştir. Ayrıca yaşanılan meslek hastalıkları sonucunda turist rehberlerinin çalışamadıkları gün nedeniyle maddi kazanç kaybına uğradıkları, psikolojik olarak yıprandıkları, stres bozukluğu yaşadıkları ve meslekten uzaklaşarak işten soğudukları tespit edilmiştir
Discrimination Based on Sexual Orientation “Homophobia in Healthcare Employees”: a Cross-Sectional Study
Full text linkIntroduction: The study was conducted to examine the attitudes of healthcare employees toward homosexuals and the factors affecting them, while homophobic thoughts and behaviors are based on heteronormative cultural beliefs and gender stereotypes. Methods: This study was planned as a cross-sectional and completed with 720 healthcare employees. The Demographic Information Form and Hudson and Ricketts Homophobia Scale were used in the study. Data were collected between January 06 and January 10, 2022. Results: The mean homophobia total score of the employees was determined as 97,503 ± 25,807. Homophobia levels of male healthcare employees, those who thought homosexuality is a disease, and those who stated that homosexuality can be caused by taking an example had increasing homophobia levels. The level of homophobia decreases in the presence of homosexual friends, those who can talk freely about homosexuality, and healthcare employees who support same-sex marriage. Conclusions: Recognition of individuals with different sexual orientations by healthcare employees will reduce homophobic attitudes toward these individuals. Examining the level of homophobia in healthcare institutions and ensuring that discriminatory attitudes or behaviors toward individuals from different sexual orientations are determined to be effective on the quality of healthcare and access to healthcare services. Policy Implications: There is a healthcare system in which patients are generally assumed to be heterosexual; healthcare employees are not prepared to work with Lesbian, Gay, Bisexual, and Transsexual patients in general. Studies conducted on this subject indicate that more studies are needed on the subject to implement a healthcare policy focusing on sexual diversity in healthcare services and to discuss healthcare practices for the Lesbian, Gay, Bisexual, and Transsexual population
