Authors: Arslan Kabasakal Sema
Published: December 2024

In football, warm-up is important for physical preparation, injury prevention, and performance enhancement. This study aimed to determine the acute effects of four different warm-up techniques, static, dynamic, self-myofascial stretching (SMR), and massage with Graston mobilization technique (GMTM), on sports performance in football. A total of 20 football players, 13 males and 7 females, who were actively studying at Yalova University Faculty of Sports Sciences and who had a football license for at least one year, were included in the study. In the study, 4 different warm-up programs were applied to each participant in random order on separate weeks, at the same time of the day and at the same day of the week. Passing, dribbling, agility, and vertical jump tests were performed before and after each warm-up program. Skewness, kurtosis values, descriptive statistics, Paired Samples T-test, and Two-Way Repeated Measures ANOVA test were used to analyze the data. As a result of the study, it was found that static warm-up, dynamic warm-up, warm-up with SMR, and warm-up with GMTM significantly increased dribbling, agility, and vertical jump performance (p0.05). No significant difference was found between the changes these warm-up types created in the total number of passes, dribbling and vertical jump performance within the scope of the warm-up type x time interaction (p>0.05), but it was determined that they created different effects on agility (p

The influence of the repetition rate of voltage pulses on the formation of plasma diffuse jets (PDJs) initiated by a capacitive discharge at an air pressure of 1 Torr has been studied. The PDJs were photographed at different frequencies and polarities of generator voltage pulses and emission spectra were recorded in the UV, visible, and IR regions of the spectrum. It has been shown that a decrease in the frequency of voltage pulses at negative polarity increases the ratio of the spectral energy density of radiation of the first positive nitrogen system to that of the second one, which contributes to an increase in the intensity of radiation in the red region of the spectrum. It has been established that a decrease in the repetition rate of voltage pulses contributes to the formation of two peaks at the front of the current pulse. The conducted studies confirm that PDJs can be considered analogous to columnar red sprites and their properties can be modeled.

Hydrogen sorption and desorption by Ti-Ni powder mechanochemically alloyed with titanium has been studied. The content of titanium in the powder mixture (Ti-Ni) - Ti was 15 wt%. Hydrogen saturation of the powder mixture (Ti-Ni) - Ti was carried out by electrochemical method. Hydrogen desorption was studied in the process of keeping the mixture in the air atmosphere. It was found that after mechanochemical alloying, the powder mixture (Ti-Ni) - Ti consisted of Ti2Ni and TiNi phases ( B 2, B 19¢). The Ti2Ni phase in the (Ti-Ni) - Ti powder mixture was represented by two modifications Ti2Ni (I) and Ti2Ni (II). The Ti2Ni (I) and Ti2Ni (II) phases had different lattice parameters. The lattice parameter of Ti2Ni (I) was (1.1285±5∙10-4) nm, and the lattice parameter of Ti2Ni (II) phase was (1.1274±5∙10-4) nm. Thus, the Ti2Ni (I) phase was inherited from the initial Ti-Ni powder, and the Ti2Ni (II) phase was formed during the mechanochemical alloying process. It is revealed that electrochemical hydrogenation of the powder mixture (Ti-Ni) - Ti for 360 min leads to a change in the lattice parameter of Ti2Ni (II), which corresponds to the parameter of the Ti2NiH2.8 hydride. It was found that after 30 days of keeping the powder mixture in the air atmosphere, the integral intensity of diffraction lines belonging to the hydride slightly decreases, indicating a slow process of hydrogen desorption. After 760 days of incubation of the powder mixture in the air atmosphere, the integral intensity of the diffraction lines belonging to the hydride decreases significantly, indicating almost complete degradation of hydride.

The method of transmission diffraction electron microscopy was used to study the grain structure, phase composition, and scalar dislocation density in commercially pure ultrafine-grained copper obtained under conditions of severe plastic deformation by torsion under high pressure. It was found that, in accordance with the nature of the dislocation structure, the grains were classified into four types: 1) the smallest grains with no substructure (practically no dislocations) - dislocation-free grains, 2) larger grains containing chaotically distributed dislocations or a net substructure, 3) the largest grains with a cellular or fragmented substructure, and 4) recrystallized grains, which have a size significantly exceeding the average size and contain randomly located dislocations and annealing nanotwins. The average value of the scalar density of dislocations in grains of each type was calculated. It was found that the severe plastic deformation by high-pressure torsion led to the formation of secondary phase particles in ultrafine-grained copper, which have a nanometric size and are localized inside, at the boundaries and at the junctions of grains.

The experimental and theoretical study of electronic spectra of paracetamol in water is presented. Two isomers of the molecule are studied. Quantum-chemical interpretation of absorption and fluorescence spectra of paracetamol is performed by the INDO method using averaged and optimized geometric parameters. It is shown that the calculation results are in satisfactory agreement with the experimental spectra. Two centers of interaction of paracetamol with water are revealed, which allowed us to reasonably construct the geometry of complexes with H-bonds of the paracetamol molecule with water.

In humans, passive smoking has been shown to alter the microbiota and increase the risk of infections by pathogens and/or opportunistic bacteria. The objective of this study was to evaluate the effect of MOS supplementation on the concentration of E. coli in the feces of passive smoking rats. Sixty young rats (23 days) were randomly allocated into four groups (n=15): supplemented or not with MOS in the diet; and  chronically exposed or not to cigarette smoke. Exposure to cigarette smoke was performed twice a day for 180 days and fecal samples were collected four times (days 0, 60, 120, and 180). After fecal collection, bacterial populations were amplified by real-time PCR. Data means were analyzed using one-way ANOVA followed by Student-Newman-Keuls post-hoc analysis, considering 5% as the level of significance. The results revealed that MOS supplementation significantly (P<0.05) reduced the E. coli population resulting from chronic exposure to cigarette smoke. The mean results of the group of rats supplemented with MOS and exposed to cigarette smoke did not differ (P>0.05) from the groups not exposed to cigarette smoke and supplemented or not with MOS. The results allow us to conclude that MOS supplementation mitigates the chronic effect of cigarette smoke on the concentration of E. coli bacteria in young rats, as a preclinical model.
Knowledge Levels and Attitudes of Pediatric Physicians Regarding Meningococcal Infections and Vaccines: A Cross-Sectional Study
Authors: Altın Hicran
Published: December 2024

Objective: Invasive meningococcal disease (IMD) clinically manifests as meningitis, meningococcemia, or a combination of both. Globally, approximately 1.2 million meningococcal cases are reported annually, resulting in 135,000 deaths. Despite meningococcal infections being a significant public health concern, widespread vaccination is not commonly practiced. The aim of this study is to evaluate the knowledge levels and attitudes of pediatric specialists and assistant doctors regarding meningococcal infections and associated vaccines.
Material and Method: This descriptive cross-sectional study included pediatric specialists and assistant doctors working in Antalya. During the study period, 170 pediatricians were identified, and it was aimed to reach at least 80% of this population. A total of 150 participants, selected via snowball sampling, participated in the survey. Data collection was carried out through face-to-face interviews and online questionnaires.
Results: Of the participants, 72.7% were pediatric specialists and 27.3% were assistant doctors. The conjugate meningococcal vaccine was recommended by 68% of the participants for all patients, by 20% for high-risk patients only, while 12% did not recommend the vaccine. The primary reasons for this hesitancy included the cost of the vaccine, concerns about adverse effects, perceptions of low vaccine efficacy, and the rarity of the disease. Additionally, 47.4% of the participants suggested that the conjugate meningococcal vaccine should be included in the national immunization schedule, followed by 39.3% who recommended the rotavirus vaccine and 13.3% who recommended the human papillomavirus (HPV) vaccine.
Conclusion: Our study found that pediatric specialists and assistant doctors had sufficient knowledge and generally positive attitudes towards Neisseria meningitidis infections and vaccines. However, the most significant barriers to vaccine administration were identified as cost, concerns about adverse effects, and the perception of low vaccine efficacy. It is anticipated that improving the knowledge and awareness of pediatricians will positively influence vaccine acceptance.

Published: December 2024

The study examined the impact of war stress on the mental health of Ukrainian civilians who stayed in Ukraine or who went abroad due to the war in Ukraine. Psychological traumatism because of the threats that war brings is manifested in increased severity of post-traumatic stress disorders, the so-called «complex trauma», depressive tendencies, sleep disorders, etc. The sample included 338 Ukrainians; post-traumatic stress disorder was observed in 35% of civilian Ukrainian women and 12.5% of civilian Ukrainian men (according to the results of an online survey using the PSL- 5 questionnaire). Among Ukrainian women who had minor children and were abroad, 40.5% had severe symptoms of PTSD. Depression measured with the PHQ-9 questionnaire showed that more than half (57.8%) of the surveyed Ukrainian women had moderate or worse depressive symptoms, in addition, 30, 1% had moderately severe or severe depression. Among men, almost a third (32.1%) had at least moderate depressive symptoms, but more severe forms occurred significantly less than those in women. The online survey on sleep disorders was conducted using the ISI questionnaire. At least moderate sleep disorders were observed in 39.5% of Ukrainian women and 28.6% of Ukrainian men. In addition, among Ukrainian men and women who were abroad, the indicators of PTSD, depression and sleep disorders were significantly higher than corresponding indicators among those who stayed in Ukraine. The study results showed the need to implement programs of medical, psychological and psychosocial support and rehabilitation, which millions of Ukrainians need.

Aim: to study a pattern of genetic and acquired thrombophilia in pregnant women with severe early-onset (eoPЕ) and severe late-onset PE (loPЕ) preeclampsia (PE).

Materials and Methods. A retrospective cohort study was conducted from January 2022 to May 2024. A total of 109 pregnant women were examined: group 1 – 45 women with eoPЕ (< 34 weeks of pregnancy), group 2 – 24 women with loPЕ (≥ 34 weeks of pregnancy), group 3 (control) – 40 women with physiologically uncomplicated pregnancy. All pregnant women were examined for lupus anticoagulant (LA) and antiphospholipid antibodies (aPL). The screening test for aPL included the quantitation of IgG/IgM antibodies against cardiolipin, phosphatidylserine, phosphatidylinositol, phosphatidic acid, and β2-glycoprotein 1 in serum or plasma using an enzyme immunoassay. Genetic thrombophilia, homocysteine, and ADAMTS-13 metalloproteinase (a disintegrin and metalloproteinase with thrombospondin type 1 motif, member 13) levels were also determined.

Results. Pregnant women with severe PE more often had genetic forms of thrombophilia (mutations in factor (F) V Leiden gene, prothrombin G20210A, and Thr165Met) and a deficiency of natural anticoagulants (antithrombin and protein S) compared to pregnant women in control group. Women in eoPE vs. loPE group were more often found to carry genetic polymorphisms in the plasminogen activator inhibitor-1 (PAI-1) and fibrinogen genes. Also, in the group of pregnant women with eoPE, the circulation of aPL, ADAMTS-13 inhibitor, and elevated homocysteine levels were more common. Pregnant women with loPE were older and more often suffered from hypertension, diabetes mellitus, and excess body weight. No significant differences between eoPЕ and loPЕ groups were found while comparing prevalence of autoimmune diseases, thrombosis in familial history, mutations in FV Leiden gene (heterozygous form), FII prothrombin gene G20210A (homozygous form), FII prothrombin gene Thr165Met (heterozygous form), antithrombin III deficiency, protein S deficiency.

Conclusion. Precise causes underlying PE remain unknown, and we are still far from understanding all the molecular, immunological, genetic, and environmental mechanisms that lead to the various clinical manifestations of placental syndromes including PE. However, the study results suggest that the presence of thrombophilic disorders, especially in the fibrinolytic system, and aPL circulation contribute to eoPE pathophysiology or progression.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract, originating from Cajal's interstitial cells and accounting for approximately 80% of all primary gastric tumors. Traditional diagnostic methods for GISTs, such as computed tomography (CT), endoscopy, endoscopic ultrasound (EUS), and fine needle aspiration biopsy (FNAB), despite their widespread use, face several limitations including diagnostic uncertainty and limited biopsy capabilities.
In this context, radiomics, which involves the analysis of image texture features, emerges as an innovative method potentially capable of enhancing the accuracy of GIST diagnosis. This approach allows to interpret of tissue changes through mathematical processing of images, which are imperceptible to the human eye, potentially facilitating more accurate detection of tumors at an early stage.
The aim of this literature review is to evaluate the advantages and disadvantages of current diagnostic methods for GISTs, as well as to assess the potential of radiomics in improving diagnostic outcomes for these tumors. The review aims to identify the best methods of application and promising directions for future research in this important field.
21. Yüzyılın Meta Savaşları: Medya Gösterileri, Soykırım, Toplumsal Kayıtsızlık ve Direniş

Published: December 2024

John Keane bu halka açık konferansında, savaş meselelerinde artık büyüklerimizin bilmediği tuhaf bir dünyada yaşadığımızı öne sürüyor. 20. yüzyılın Soğuk Savaşı’ndan ve yakın zamanda konuşulan 2. Soğuk Savaş'tan son derecede farklı bir dünyadayız. Tahrip edici meta savaşlar çağındayız. Günümüzde dijital iletişim teknolojileri, yalnızca Hellfire hassas güdümlü havadan yere füzeler ve düşman uydularının kontrolünü ele geçirebilen karmaşık siber silahlar gibi savaş yöntemlerini ve silahlarını ürkütücü bir şekilde geliştirmekle kalmıyor; aynı zamanda, paradoksal bir şekilde, savaşın medyadaki temsillerini de biçimlendiriyor. Hükümetlerin, askeri halkla ilişkiler propagandacılarının, son dakika habercilerinin, askerlerin ve vatandaşların oluşturduğu bu değişen medya temsilleri, savaşları adeta bir “oyun” gibi sunarak, savaşın dehşetini estetize etmekte ve milyonlarca insanı, kan, zulüm ve soykırım boyutundaki yıkımlardan arındırılmış gibi görünen bu savaşlara karşı kayıtsızlığa itmektedir. Özellikle Atlantik bölgesinin eski demokrasilerinde bu yeni meta savaşları, toplumsal kayıtsızlık, duygusal kopukluk ve kendi meşguliyetleriyle boğulmuş insanların umursamazlık hislerini beslemektedir. Ancak bu toplumsal kayıtsızlığın karşısında meta savaşlar çağına özgü bir karşı çıkış da mevcuttur. Bu karşı çıkış, isyancı gazetecilerin bu savaşların korkunç gerçeklerini dijital olarak açığa çıkardığı, onların ahlaki ve pratik gerekliliklerini sorguladığı ve dünyanın her yerindeki sivillere meta savaşlara maruz kalmak zorunda olmadıklarını, hatta bir gün savaşın her türünün ortadan kaldırılmasının zorunlu olacağı bir zamanın geleceğini öğrettiği yeni medya platformlarının doğuşudur. Prof. Keane’in bu dersini Özümsu Alagöz’ün çevirisiyle Türk iletişim akademisinin ilgisine sunmaktan memnuniyet duyarız.

The main purpose of this study is to investigate the test anxiety status of high school seniors in terms of different variables. The sample group of this research is a total of 366 high school students, 169 females (46.2%) and 197 (53.8%) male students, who studied in high schools in Mersin province in the 2021-2022 academic year. The mean age of all participants in the research is 17.28, their age range is 16-21, and the standard deviation (SD) of the group is .49. Data for the study was collected using the Test Anxiety Inventory for Children and Adolescents and the Personal Information Form. Descriptive statistics, Pearson correlation analysis, t-test for independent groups and one-way analysis of variance (ANOVA) were also used in the data analysis of the results. According to the obtained results of the research, it was concluded that the test anxiety levels of high school seniors differed depending on these variables, such as gender, having their own rooms, making time for daily work, eating habits, receiving help from a psychological counsellor, following a regular study schedule, sleeping patterns and their own perception of success. On the other hand, taking private lessons was found to have no significant effect on test anxiety among group participants.

Published: December 2024

This study examines pre-service science teachers' cognitive structures and visual images toward the perception of scientists and engineers. The study group of the research consists of 195 students studying at a state university in Ankara in the 2023-2024 academic year. The survey model, one of the quantitative research methods, was used in the study. The study data were collected with an open-ended question about scientist and engineer, a Word Association Test (WAT) related to the concepts of scientist and engineer, and a draw a scientist and draw an engineer test. The data obtained from the study were analyzed using content analysis. Participants mainly explained the differences between scientists and engineers in their working environments. The pre-service teachers associated scientist with the word laboratory (n=140) the most and obsessive (n=8) the least. They associated engineer with the word machine (n=101) and physics (n=8). In the drawings, scientists were mainly depicted as wearing lab coats, having messy hair, working in the laboratory with experimental materials, being sad or thoughtful, wearing glasses, and being male. Notably, pre-service teachers partially eliminate traditional ideas as the grade level increases. On the other hand, the engineer is mainly seen as a man wearing a work apron or daily clothes, with smooth hair, beardless, working in an open area with construction materials or motor vehicles, partially happy and thoughtful, and wearing a helmet/hat. Whether the grade level increase changed their mind about this idea is not determined.

Published: December 2024

Background: Thalassemia major, a severe form of inherited anemia, requires lifelong blood transfusions to manage the condition and sustain hemoglobin levels. However, these repeated transfusions often lead to iron overload, which can deposit in various organs, including endocrine glands and disrupt normal hormone production. One such affected gland is the parathyroid, responsible for regulating calcium and phosphate balance through parathyroid hormone (PTH) secretion. This study aimed to assess the parathyroid status in children with thalassemia major.
Methods: This case-control analytical study design was considered to assess the parathyroid status in children with thalassemia major. The study was carried out at the Department of Pediatric Hematology and Oncology, Dhaka Medical College Hospital, Dhaka, from July 2012 to June 2013. A total of 40 children with thalassemia major (termed as case) and another 32 normal children (termed as control) were included in the study. Data were analyzed using SPSS (Statistical Package for Social Sciences) version 16.
Results: The study found that children with thalassemia major had significantly lower parathyroid hormone (PTH) levels and higher phosphate levels compared to healthy controls, though calcium levels were similar between groups. Thalassemia patients, primarily receiving blood from professional donors, underwent transfusions for an average of six years, with limited use of chelation therapy (15%). Hypoparathyroidism was significantly more common in thalassemia patients (10%) compared to controls, with 25% also showing hyperphosphatemia. No significant differences were observed in age or sex distribution between the groups.
Conclusions: It can be concluded children with thalassemia possess significantly low serum PTH and high phosphate levels. The serum calcium level does not alter significantly compared to healthy children of similar age and sex. The findings call attention to the critical need for early intervention, regular endocrine screening and diligent chelation therapy in managing thalassemia major.

Published: December 2024

Background: The increasing prevalence of overweight and obesity among children and adolescents in Bihar has become a critical public health concern, coexisting with the state’s long-standing challenge of undernutrition. This study aimed to investigate the prevalence trends, key determinants, and demographic disparities of overweight and obesity among children and adolescents in Bihar to identify actionable insights for public health strategies.
Methods: Data from the National Family Health Surveys (NFHS-4, 2015–16, and NFHS-5, 2019–21) were analyzed along with supplementary reports from WHO and UNICEF. The study included children aged 5–9 years and adolescents aged 10–19 years, with overweight and obesity classified using WHO growth standards (BMI-for-age > +1 SD and > +2 SD, respectively). Descriptive statistics were employed to assess prevalence trends, while multivariate logistic regression identified behavioral and environmental risk factors, including screen time, physical activity, and dietary habits.
Results: Overweight prevalence doubled among children aged 5–9 years (1.2% to 2.4%) and increased among adolescents (3.2% to 4.5%). Obesity among adolescents also doubled, rising from 1.1% to 2.3%. Urban children exhibited higher rates of overweight (6.2%) compared to rural children (2.8%). Behavioral factors such as physical inactivity (<30 minutes/day; OR=3.2) and prolonged screen time (>4 hours/day; OR=2.5) were significant predictors. Frequent consumption of fast food and sugary beverages further increased the risk.
Conclusions: The findings highlight the urgent need for targeted interventions, including promoting physical activity, regulating unhealthy food environments, and embedding nutrition education in schools. A multisectoral approach is critical to addressing the dual burden of malnutrition in Bihar’s children and adolescents.

Published: December 2024

Background: Depression in children and adolescents has been increasing worldwide especially in the adolescence. Despite its high prevalence and its substantial impact, the detection and its treatment in primary care setting have been suboptimal. To estimate the prevalence of depression among 8-17 years attending OPD at a tertiary care hospital and the risk factors associated with it.
Methods: A cross-sectional study done among 400 participants of 08 to 17 years of age presenting to Pediatric and Medicine Outpatient departments of a Tertiary Care Hospital at Puducherry. A three-step process on diagnosis was involved. Step 1 included screening for psychiatric morbidities using Tamil and English version of Strengths and Difficulties Standardized Questionnaire. Those scoring above 19 were subjected to a second screening test for depression using Centre for Epidemiological Studies Depression scale for Children. All these participants were referred for psychiatric assessment irrespective of their CES-DC score for diagnosis. The data was analysed by descriptive statistics.
Results: Among the study population, 49 (12.25%) participants had depression. Among the participants with 8 to 12 years of age, 10 (5%) participants had depression. Among the participants with aged 13 to 17 years, 39 (19.5%) participants had depression. The risk factors significantly associated with depression include age group, friends, sickness, constant fidgeting/squirming, temper tantrum, bullying, addiction in parents, parent education.
Conclusion: Owing to the prevalence of depression in our study especially in the late adolescent, the importance is to be given for early diagnosis and appropriate management.

Authors: Srinivas Suprith Amblihalli , Pol Ramesh
Published: December 2024

Background: Dengue fever is a mosquito-borne viral disease that presents as asymptomatic or can clinically manifest with symptoms like hemorrhagic fever and shock. Alteration of various other hematological parameters includes leukopenia, thrombocytopenia, hematocrit changes, and liver enzyme alteration. this study aimed to investigate dengue patients' clinical profiles, laboratory parameters, and outcomes across different severity levels.
Methods: This is a prospective hospital-based study of 125 patients conducted at S. Nijalingappa medical college, Bagalkot over 18 months from August 2022 to February 2024. the study included 125 cases with serologically confirmed (NS1ag and/ IgM) between 1 to 14 years and categorized according to WHO classification.
Results: Out of 125 patients, 62 and 33 had dengue with and without warning signs, and 30 had severe dengue, 52% of cases had leucopenia, and thrombocytopenia was present in 105 (84%) cases with significantly higher in severity groups. Elevated SGOT 108 (86.4%) and SGPT 72 (57.6%) were commonly seen in disease severity groups. Liver dysfunction was observed in 86.4% of patients. All patients survived and improved with appropriate treatment.
Conclusions: This study highlights the importance of clinical and hematological parameters in the early recognition and management of severe dengue cases. Liver dysfunction was common in severe cases. Despite the varying severity, all patients in this cohort had favorable outcomes, emphasizing the effectiveness of proper management strategies.
Variations in physiological responses to painful stimuli in preterm and term neonates: an observational study
Authors: Agrawal Pranav , Samayam Purnima
Published: December 2024

Background: Appropriate neonatal pain assessment and management is a key component of quality medical care. Assessment of pain, however, is a challenge due to their inability to verbalize this subjective sensation. Preterms are hyper-sensitive to pain and experience it for prolonged periods but it is postulated that they may not express it as robustly and reliably as term neonates. This paper aims to assess and compare the behavioral and physiological pain responses in these groups.
Methods: This prospective observational study was conducted in the outpatient and post-natal wards of a tertiary care teaching hospital. 90 clinically stable term and late preterm neonates requiring IV cannulation, IV blood sampling or heel prick were included. NIPS Pain Scale Scores and physiological parameters (heart rate, respiratory rate, SpO2, mean arterial pressure, total crying time) were recorded before and after the procedure.
Results: 90 neonates were analysed. Significant pain response was noted in both groups post-procedure. In response to the same procedures, preterm neonates demonstrated lower NIPS Scores (4.00 vs. 4.93, P=0.003) and shorter cry times (64.30s vs. 87.35s, P=<0.05). Also noted were higher heart rates and respiratory rates with a prolonged fall in SpO2 and Mean Arterial Pressures in this group. 
Conclusions: Preterms, compared to term neonates demonstrate a blunted behavioral response to pain but a heightened and prolonged physiological response. This potential underestimation of pain in preterms indicate the need for incorporation of behavioral cues, physiological parameters and gestational age in the assessment of pain in newborns.

Published: December 2024

In this case series, we evaluated the clinical profiles and short-term outcomes of four pediatric patients diagnosed with SARS-CoV-2-associated multisystem inflammatory syndrome (MIS-C), treated with Methylprednisolone and/or intravenous immunoglobulin (IVIg). All cases were managed at a tertiary care hospital in the Rohilkhand region and met the WHO diagnostic criteria for MIS-C. The study period spanned from May to December 2021, with the primary outcome being the resolution of fever. Secondary outcomes included the length of hospital stay, mortality, duration of respiratory or inotropic support (if applicable), and the time to normalization of inflammatory markers. The four cases presented with varying degrees of MIS-C involvement: two patients had significant cardiac involvement, one displayed neurological symptom, and another had systemic inflammatory manifestations. All patients received IVIg (2 g/kg) and Methylprednisolone (2 mg/kg/day). Fever resolved within 3-5 days of treatment, and inflammatory markers normalized within a median of 5 days. Two cases required inotropic support for shock, and one required high-flow nasal cannula (HFNC) oxygen for respiratory distress. No mortality was observed in this cohort. In conclusion, treatment with IVIg and Methylprednisolone was associated with favorable outcomes in these MIS-C cases.

Published: December 2024

Mycoplasma pneumoniae is a common cause of community-acquired pneumonia and respiratory tract infection in children. While traditionally known for its respiratory manifestations, extrapulmonary manifestations of Mycoplasma pneumoniae infections are rare, particularly autoimmune hemolytic anemia (AIHA). Emerging evidence suggests its association with AIHA in pediatric patients, especially with severe respiratory involvement. Here, we present a case of a child with cold AIHA secondary to Mycoplasma pneumoniae infection without marked pulmonary manifestations, from a resource limited setting, highlighting the importance of considering atypical presentations of this pathogen in pediatric patients. Understanding this association is crucial for timely diagnosis, appropriate management, and improved outcomes in affected children.

THE LONGEST CENTURY OF ARMENIA: A QUEST FOR BALANCING BETWEEN THE ROMAN–SASANIAN IN THE FOURTH CENTURY
Authors: Cinemre İlhami Tekin
Published: December 2024

This study explores the intricate political and religious dynamics that shaped Armenia during the fourth century, focusing on the impact of Roman and Sasanian imperial interventions and the internal divisions within Armenia. The division of Armenia into Roman and Sasanian spheres following the agreements of 387 resulted in a bifurcated political structure, with significant implications for the region’s stability. The rivalry among local aristocratic families, known as naxarars, played a crucial role in this fragmentation, as their shifting loyalties and internal conflicts facilitated external manipulation by both empires. Additionally, the religious conflict between Christianity and Zoroastrianism further complicated the political landscape, contributing to the erosion of centralized control and exacerbating internal strife. The study examines how these factors combined to influence the political trajectory of Armenia, from the internal struggles during the reign of King Tiridates to the eventual consolidation of Sasanian’s control under Vramšapuh. By analyzing these dynamics, this research highlights the complex interplay of internal and external forces that defined Armenia’s historical trajectory in this period, offering insights into the broader implications of imperial rivalry and religious conflict in shaping regional politics.
