Published: September 2024

Background: Undernutrition is a major problem in developing countries, especially among tribal pre-school children. Many studies have been undertaken on preschool tribal children in different parts of India, but by considering different ecological zones, no previous studies have been taken into account for determining nutritional status using head circumference. Head circumference for age Z-score (HCAZ) is also a useful index for determining the nutritional status of pre-school children. Objectives: The aim of the study is to assess the nutritional status based on head circumference of preschool children of the Bhil, Dhodia and Kinnaura tribes. Methods: The present study was undertaken among 509 boys and 476 girls. Among which, 168 boys and 185 girls belonged to the Bhil tribe from Barmer district, 164 boys and 142 girls belonged to the Dhodia tribe from Valsad district, and 177 boys and 149 girls belonged to the Kinnaura tribe from Kinnaur district. WHO Child Growth Standards (2007) were utilized to determine Z-scores for head circumference for age (HCAZ). The standard formula was used to compute HCAZ: Z-score= (X- Median value of WHO 2007)/ standard deviation, WHO (2007). Moderately undernourished: <-2SD and severely undernourished: <-3SD were considered following the WHO standard (2007). Results: From this study, it was found that among Bhil preschool children, 28.3% of boys and girls are undernourished, 33.6% of boys and 31.3% of girls are suffering from malnutrition among Dhodia boys, and 13.5% of boys and 17.2% of girls are undernourished among Kinnaura tribe. Conclusion: Regular intervention programmes need to be done by the authority to spread awareness among the people of these tribal communities so that the health condition of preschool children improves.
THE MODIFIED MEAN ABSOLUTE DEVIATION INTEGER LINEAR PROGRAMMING MODEL FOR GLOBAL PORTFOLIO ASSET ALLOCATION
Authors: Hadi Nadia Edmaz Abdul , Khan Sahubar Ali Mohamed Nadhar
Published: September 2024

This study develops a practical yet robust Mean Absolute Deviation (MAD) Mixed-Integer Linear Programming (MILP) model for a global investment portfolio tailored to the constraints faced by Malaysian retail investors, such as transactional fees and foreign currency exchange spreads, to provide more accurate estimations of portfolio returns. The MAD ILP model is modified to address these factors, aiming to enhance utility and efficiency. The study utilizes a Maybank 12-month fixed deposit cash account and ten selected Exchange-Traded Funds (ETFs) from iShares, Vanguard, and State Street Global Advisors for global portfolio construction. Forecasting techniques were utilized to generate expected returns for the ETFs and foreign currency exchange spreads. Based on the MAD model proposed by Konno and Wijayanayake (2001), the study introduces three modifications: incorporating transaction cost elements specific to Malaysian investors, including foreign currency exchange spreads in return calculations, and transforming the model from mixed-integer to pure integer model to accommodate minimum transaction lot constraint. Verification and validation exercises demonstrate the model’s ability to replicate real-world portfolio construction and reliable simulations. The model offers a practical tool for self-ascribed investors aiming to optimize global investment portfolios while considering unique constraints and transaction costs.

Authors: Adepoju Akeem Ajibola , Bello Akanji Olalekan , Isa Alhaji Modu , Adesupo Akinrefon , Olumoh Jamiu S.
Published: September 2024

The Sine-Exponential (Sine-E) distribution is a probability distribution that combines the periodic behavior of the sine function with the decay characteristic of the exponential function. This study addresses the problem of identifying the most accurate and reliable estimation method for the parameter of the Sine-E distribution. The objective is to evaluate various parameter estimation techniques, including Maximum Likelihood Estimation (MLE), Least Squares Estimation (LSE), Weighted Least Squares Estimation (WLSE), Maximum Product of Spacing Estimation (MPSE), Cramer-von-Mises Estimation (CVME), and Anderson-Darling Estimation (ADE), using Mean Square Error (MSE) as the criterion for determining the technique with the minimum error. The study’s findings reveal that as sample size increases, the parameter estimates for all techniques converge to the true parameter value, with decreases in bias, MSE, and mean relative estimates. Among the techniques evaluated, the MPSE method consistently provides estimates closest to the true parameter value and exhibits the least bias and lowest MSE across small, moderate, and large sample sizes, making it the best estimator for the Sine-E distribution.

Background: Acute ST-elevated myocardial infarction is a life-threatening condition. Presence of fragmented QRS (fQRS) after acute STEMI is associated with alteration of myocardial activation due to myocardial scar and myocardial fibrosis. Previous studies have suggested that fQRS in acute STEMI is associated with increased mortality, morbidity, sudden cardiac death and recurrent adverse cardiovascular events. The study was designed to assess the association of fQRS complex with short-term outcome (in hospital and 30 days follow up) in patients with acute ST elevation myocardial infarction.
Methods: This prospective cohort study was conducted in the Department of Cardiology, Dhaka Medical College Hospital among the STEMI patients who were thrombolysed. All patients underwent serial ECG at admission, within first 12 hours, at 24 hours and at 48 hours for detecting the presence of fQRS complex. Patients showing fQRS involving infarct territory within 48 h of admission were included in the “fQRS group” and those who did not develop fQRS within 48 h of admission were included in the “without fQRS” group. 114 patients had fQRS complex and 104 patients were without fQRS in their ECG. In-hospital outcomes such as: death, heart failure, significant arrhythmias (VT, VF AF, SVT, 20 AV block, CHB), cardiogenic shock were recorded. Among the study patients, sixteen patients were lost to follow up in 30 days of index hospitalization. Finally, 202 patients were tracked for follow up regarding death or re hospitalization information by personal contact or over telephone. Statistical analysis was performed using the statistical package for social science (SPSS) 21.0 software for windows.
Results: Appearance of fQRS complex occurred at admission, within first 12 hours, 24 hours and 48 hours in 53.5%, 23.7%, 14.9% and 7.9% cases respectively. During index hospitalization, development of cardiogenic shock (27.19% vs 11.54%), heart failure (23.68% vs 9.62%) and significant arrhythmias were significantly higher in fQRS group (42.10% vs 11.53%, p<0.05). Although mean duration of hospitalization was similar in both groups (p>0.05), but in-hospital mortality was higher in fQRS group (11.40% vs 3.85%, p<0.05). Rate of re-hospitalization was significantly higher in patients with fQRS complex (21.69% vs 7.29% p<0.05). Overall mortality within 30 days of index hospitalization follow-up also differs significantly in presence of fQRS complex (19.81% vs 5.2%; p =0.006).
Conclusion: Presence of fQRS complex is associated with adverse short-term outcome in patients with acute ST elevation myocardial infarction. Hence, these patients need more aggressive and early invasive treatment to reduce morbidity and mortality.

Published: September 2024

Introduction: Coronary artery disease is one of the leading causes of non-communicable diseases related deaths worldwide. Decreased serum high-density lipoprotein level are associated with an increased severity of coronary artery disease. Present study aims to evaluate the association between this low HDL level and the severity of coronary artery disease assessed by SYNTAX Score in patients with non-ST elevation Myocardial infarction.
Materials & Methods: This was a cross sectional study conducted in the Department of Cardiology at National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, from May 2020 to April 2021, on 170 admitted adult patients of non-ST elevated myocardial infarction undergoing coronary angiogram. Study population was divided in two groups; Group-I: Respondents with HDL level ≥ 40 mg/dl, Group-II: Respondents with HDL level < 40 mg/dl. Transthoracic echocardiography was done before coronary angiography. All coronary lesions with diameter stenosis > 50% in vessels > 1.5 mm was scored, using the SYNTAX algorithm. A low score was defined as ≤ 22, an intermediate score as 23 to 32, and a high score as ≥ 33. To determine statistical significance, Chi-square test and independent sample t-test were considered according to applicability. P value of < 0.05 was considered statistically significant.
Results: Highest proportion of respondents were from age group 51 – 60 years, 48.2% and 43.5% for group-I and group-II respectively. Study population was male predominant, 88.2% among patients from group-I and 83.5% among patients from group-II. Smoking was the most prevalent risk factor for group-I patients at 58.8%. Hypertension was the most prevalent risk factor for group-II patients at 45.9%. Mean total cholesterol, low-density lipoprotein and high-density lipoprotein were higher among patients from group-I than group-II and these differences were statistically significant (p < 0.05). Mean triglycerides was higher among patients from group-II than group-I and this difference was statistically significant (p < 0.05). Triple vessel was more prevalent (36.5% vs 22.4%) among patients from group-II than group-I and this difference was statistically significant (p < 0.05). Mean SYNTAX score (SS) was higher among patients from group-II than group-I, 17.4 ± 8.6 and
11.5 ± 8.4 respectively, and this difference was statistically significant (p < 0.05). There was strong negative correlation between HDL level and Syntax score (r = - 0.299, p < 0.05).
Conclusion: Present study demonstrated significant negative correlation between low serum HDL levels with severity of coronary artery disease among patients with non-ST elevated myocardial infarction. Serum HDL levels can be used as a predictor for the severity of coronary artery disease among such patients.

Shrimps are among the most intriguing groups within the Decapoda order. In Bangladesh, penaeid shrimps hold significant economic value as a major export commodity. This study aimed to analyze the morphometric and molecular characteristics of penaeid shrimps in Bangladesh. Two species of penaeid shrimp, Penaeus pulchricaudatus and Kishinouyepenaeopsis incisa were identified as new records in Bangladesh waters. A distinguishing feature of P. pulchricaudatus is its dark brown transverse bands that do not extend to the lower half of the carapace. The identification of these species was confirmed using both morphometric characteristics and DNA barcoding techniques. Two sequences were generated for these species utilizing the 16S rRNA gene marker. The findings reveal two new records of shrimp species in Bangladesh, expanding the known diversity of shrimp in the region and highlighting the presence of previously undocumented species.

Bu yeniliklerin en önemlilerinden olan 1950 Kuşağı öykücülüğü, Türk edebiyatında önemli dönüm noktalarından birisidir. Bu kuşak, Batıda ortaya çıkan varoluşçuluk ve gerçeküstücülükten etkilenmiştir. Dolayısıyla bu kuşağın öykülerinde bu edebî ve felsefi anlayışların izlerini görmek mümkündür.
Türkiye’de bütün bunlar olurken, yurt dışında yaşayan ve Türk edebiyatını oradan takip eden Feyyaz Kayacan da varoluşçuluk ve gerçeküstücülük etkisiyle yazdığı öykülerle dergilerde görünmeye başlar. Fransızca, İngilizce ve Türkçe eserler veren Kayacan, aslında edebiyata Fransızca şiirler yazarak girer. Henüz on altı yaşındayken ilk şiir kitabını yine bu dille yayımlar. İngiltere’de okurken Fransızca yazan bir şair olarak, Türk şair ve yazarlarını keşfederek 1950’lerin başında Türkçe yazmaya başlar. Feyyaz Kayacan, gerçeküstücü anlatımıyla ham gerçekliği ters yüz etmenin yanı sıra varoluşçu eğilimiyle de öykülerinde postmodern edebiyatın özelliklerini yansıtır. Kayacan, kuşağının birçok öykücüsü gibi geleneksel öykünün yapı anlayışını, verili dil ve anlatım mantığını tahrif ederek yapı, içerik, dil bakımından devamlı yenilik arayışını canlı tutan bir yazardır. Dille oynaması ve dili şiirleştirme eğilimi, klişeleri bozması, cümle mantığını değiştirmesi onun öykülerinde en çok görülen yeniliklerdendir. Kayacan, öykülerinde modern insanın çıkmazlarını, yalnızlığını, bunalımını ironik bir anlatımla verir. Kısacası Feyyaz Kayacan, 1950 Kuşağı içerisinde özgün bir yeri olan önemli bir yazardır.
OSMANLI DÖNEMİ KESKİN’DE MADENCİLİK FAALİYETLERİ

İnsanlık tarihi boyunca madenler hem ekonomik açıdan hem de kullanım alanlarının çeşitliliği sebebiyle büyük bir öneme sahip olmuştur. Osmanlı Devleti klasik dönemde mali ve askerî açından madenleri belirli bir düzen içerisinde işletmeye özen göstermiştir. Bu doğrultuda Tanzimat’a kadar olan süreçte madenler genellikle devlet eliyle işletilmiştir. Zengin maden yataklarına sahip olan Anadolu’da birçok maden işletmesi bulunmaktaydı. Keskin kazasında yer alan Gümüşkan Maden-i Hümayunu’nunda 1820’lerden itibaren kurşun, gümüş ve simli kurşun üretilmeye başlanmıştır. 1860 yılına kadar maden bölgeye gönderilen emin veya müdürler vasıtasıyla işletilmiştir. Bu tarihten itibaren madende yaşanan cevher sıkıntısı teknolojik yetersizlik vb. sebeplerden dolayı üretim durdurulmuştur.
Tanzimat’ın ilanının ardından her alanda olduğu gibi Osmanlı madenciliğinde de değişim ve dönüşümler yaşanmaya başlanmıştır. Bu doğrultuda madenlere yönelik idari teşkilatlanmalar kurulmuş ve birçok yabancı uzman da istihdam edilerek reorganizasyon süreci yaşanmıştır. Kırım Savaşı sonrasında Avrupalıların Osmanlı madenlerine olan ilgisinin artması madenlere yönelik hukuki düzenlemeleri de beraberinde getirmiştir. 1861’de ilk Maden Nizamnamesi’nin kabul edilmesinden sonra tecrübe ve deneyimler neticesinde 1869, 1887 ve 1906 tarihlerinde bir öncekini ilga eden yeni maden nizamnameleri yürürlüğe girmiştir.
XIX. yüzyılın sonlarına doğru maden arama ve ihalelerinde büyük bir artış yaşanmıştır. Bu doğrultuda uzun yıllardır madencilik açısından âtıl durumda bulunan Keskin’de Denek Madeni olarak nitelendirilen bölgede ihaleler gerçekleşerek üretim tekrar başlamıştır. XX. yüzyılın hemen başında maden işletmeciliğini ele alan Fransızlar, önemli miktarda simli kurşun üreterek iç piyasadan ziyade Fransa ve Yunanistan’a da ihracat gerçekleştirmişlerdir. 1906-1911 yılları arasında Osmanlı’daki simli kurşun üretiminin %66’sı Denek Madeni’nden sağlanmıştır.
Keskin’e bağlı köylerde ve Denek Madeni civarında 1914’e kadar olan süreçte birçok maden arama ruhsatı verilerek bazı ihaleler gerçekleşmişse de I. Dünya Savaşı’nın başlamasının ardından faaliyetlerin tamamı durdurulmuştur. Böylelikle Keskin’de bundan sonraki süreçte madencilik âtıl bir vaziyette kalmıştır.

Osmanlı padişahları, kendilerine itaatle bağlı ve verilen emirleri yerine getirmeye çalışan görevlileri, şevklerini artırmak amacıyla taltif etmişlerdir. Ödüllendirilecek kişilere genellikle hilat ya da kürk giydirilip hançer gibi kıymetli eşyalar verilmiştir. Özellikle XVIII. yüzyılla birlikte daha yaygın kullanılan yöntem, merkez görevlisi olarak addedilen kimi makamların taltif edilmek istenen kimselere paye suretiyle tevcihi olmuştur. Buna göre başkentte bulunup sarayda hizmet eden kimselerin işgal ettikleri görevler, ilerleyen dönemlerde yalnızca paye olarak taşradaki kimi âyanlara verilmiştir. Böylece onların sadakatlerinin, çalışkanlıklarının ve zor dönemlerde Osmanlı Devleti için faydalı faaliyetlerinin takdir edildiği etrafa gösterilmiştir. Dolayısıyla aslında sahip oldukları payelerle ilgili başkentte hiçbir vazifeleri bulunmayan seçkinler, bir anda kendilerini bir görevin içinde bulmuşlardır. Ancak payeler sadece bir takdir aracı olarak kullanılmamıştır. Bunlar, merkez-taşra ilişkilerinde sorun yaşandığı dönemlerde taşra seçkinleri için tehdit unsuru haline gelmiştir. Nitekim Osmanlı yönetimi, gücünü kırmak istediği âyanları, daha önce uhdelerine verdiği paye ve görevlere dayanarak, İstanbul’a çağırıp onların burada fiilen hizmet etmelerini istemiştir. Bu sayede taşra seçkinlerinin nüfuz bölgelerinden bağını koparıp güçlerini zayıflatılmayı amaçlamıştır.
Bu çalışmada, Osmanlı Devleti’nin âyanlara payeleri hangi şartlar neticesinde verdiği Çapanoğulları örneğinde incelenmiştir. Payelerin taşra seçkinleri tarafından talebi, isteğin uygun bulunması, ilerleyen dönemlerde Osmanlı yönetimi ile taşra seçkinlerinin menfaatlerinin çakışması ve paye verilen kimselerin İstanbul’a çağırılmaları süreçleri arşiv kaynaklarına dayanılarak ortaya konulmuştur.
TOPLUMSAL CİNSİYET VE BOŞ ZAMAN: DOĞA YÜRÜYÜŞÜ GRUPLARINDA KENTLİ ORTA YAŞLI KADINLAR

Demografik dönüşüm geçiren Türkiye’de artan orta yaşlı kentli nüfusun ihtiyaçları da farklılaşmakta ve sağlıklı yaşlanma için gereken spor ve sosyalleşme ihtiyacını karşılayan doğa yürüyüşü gruplarına ilgi artmaktadır. Özellikle kentli, bekar ve orta yaş grubundaki kadınlar ve erkekler için doğa yürüyüşü grupları sosyalleşme ile birlikte önemli bir sportif faaliyet haline gelmektedir. 2023 yılında Ankara’da gerçekleştirilen bu çalışma ile orta yaş grubu kadınların doğa yürüyüşü gruplarına katılma motivasyonları, beklentileri ve sosyalleşme ihtiyacı toplumsal cinsiyet perspektifinden incelenmektedir. Nitel araştırma yaklaşımının benimsendiği araştırmanın ana sorusu doğa yürüyüşü gruplarının kentli orta yaş grubunun hangi ihtiyaçlarına yanıt verdiği ve bireyler üzerindeki etkileridir. Araştırma kapsamında 15 katılımcı ile yarı yapılandırılmış soru rehberi eşliğinde derinlemesine görüşmeler, 10’dan fazla katılımcıyla enformel sohbet ve yürüyüş gruplarında gözlem yapılmıştır. Bulgular özellikle Covid-19 pandemi sonrasında bu grupların artan önemine işaret etmektedir. Doğa yürüyüşü grupları sadece fiziksel değil psikolojik, sosyal ve faydaları ile de kentli orta yaş nüfusun kişisel refahı ve iyilik hali için önemli bir işlev görmektedir. Doğa yürüyüşü gruplarının profili ancak üretken yaşamdan sonra serbest zaman aktivitelerine katılan kadınlar için bu grupların toplumsal ve psikolojik önemine işaret etmektedir. Literatürde aktif ya da sağlıklı yaşlanma olarak tanımlanan süreçler Türkiye gibi genç emeklilerin sayısının hızla arttığı ülkeler için önemli politik bir alana dönüşmektedir. Pek çok gelişmiş Batı Avrupa ülkesinin yanı sıra doğal zenginliklere sahip Hindistan ya da Kazakistan gibi ülkelerde ulusal ve yerel yönetimler tarafından desteklenen serbest zaman aktiviteleri konusunda Türkiye’nin de özellikle kadınları teşvik edecek politika geliştirmesi önemlidir.

m6A modification is a crucial epigenetic regulatory mechanism in diffuse large B-cell lymphoma (DLBCL). Low-dose cardiotonic drugs have been shown to induce apoptosis in DLBCL cells through epigenetic modulation. However, the involvement of the cardiotonic drug ouabain in the malignant progression of DLBCL remains unclear. Our study revealed that ouabain indeed contributes to the malignant progression of DLBCL through m6A modification. Through qPCR analysis, we observed a negative correlation between ouabain concentration and the expression levels of the demethylase ALKBH5 and the m6A-binding protein IGF2BP2 in DLBCL cells. Furthermore, high expression levels of ALKBH5 and IGF2BP2 were identified in both the GEO database and DLBCL patient tissue samples. Notably, elevated ALKBH5 and IGF2BP2 promoted cell proliferation both in vitro and in vivo. Inhibition of their expression rendered DLBCL cells more sensitive to ouabain treatment, resulting in significant suppression of cell proliferation, G1/S phase cell cycle arrest, and increased apoptosis. In summary, our results clarify that the demethylase ALKBH5 and the m6A-binding protein IGF2BP2 are involved in the malignant progression of DLBCL, and that the cardiotonic drug ouabain can inhibit the proliferation of DLBCL cells by inhibiting the expression of ALKBH5 and IGF2BP2, which provides new insights into the targeted treatment of DLBCL.

Целью данного исследования входила оценка влияния комбинированного препарата розувастатина с эзетимибом на уровни липидов, С-реактивного белка крови и показатели артериальной жесткости у лиц с гиперлипидемией 2а типа. Материал и методы. В исследование включили 40 человек, завершили курс лечения 37 человек (59% женщин, средний возраст 57±8 лет). Перед началом исследования и через 12 недель приема фиксированной комбинации розувастатина с эзетимибом 20/10 мг в сыворотке крови определяли уровни общего холестерина, триглицеридов, ХС ЛВП, глюкозы, ферментов крови, С-реактивного белка. Содержание холестерина липопротеидов низкой плотности (ХС ЛНП) вычисляли по формуле Фридвальда. Для оценки артериальной жесткости применяли три метода: ультразвуковое исследование сонных артерий, аппланационная тонометрия, объемная сфигмография. Результаты. На фоне терапии продемонстрировано значимое снижение общего холестерина, триглицеридов, ХС ЛНП, С-реактивного белка, глюкозы на 41, 25, 56, 38 и 6%, соответственно. Не отмечено изменения параметров артериальной жесткости при УЗИ: индекс жесткости β, коэффициентов растяжимости и податливости. В то же время выявлено снижение показателя артериальной жесткости по данным аппланационной тонометрии - каротидно-феморальной скорости пульсовой волны с 9,4±1,5 до 9,0±1,1 м/с (р< 0,01) на фоне значимого снижения  уровня артериального давления, при этом антигипертензиваня терапия не изменялась. Заключение. В результате терапии комбинированным препаратом розувастатина с эзетимибом 20/10 мг в течение 3 месяцев показано значимое снижение уровня холестерина липопротеидов низкой плотности, С-реактивного белка и улучшение показателя артериальной жесткости каротидно-феморальной скорости пульсовой волны
