Myocardial Extracellular Volume Expansion in Type 2 Diabetes Is Associated With Ischemic Heart Disease, Autonomic Neuropathy, and Active Smoking
Authors: Bojer Annemie Stege , Sørensen Martin Heyn , Gæde Peter , Madsen Per Lav 
Published: October 2022

OBJECTIVE
Myocardial interstitial fibrosis expands the extracellular volume (ECV) and in patients with type 2 diabetes is implicated in development of heart failure. ECV can be determined with gadolinium contrast MRI. We investigated which known risk factors for cardiovascular disease were associated with increased ECV in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS
A total of 296 patients with type 2 diabetes and 25 sex and age-matched control subjects were included in a cross-sectional MRI study. The influence of risk factors on ECV was investigated with multiple regression analysis.

RESULTS
Control subjects and patients with type 2 diabetes without complications had similar ECV (mean ± SD 27.4 ± 2.1% vs. 27.9 ± 2.6%, P = 0.4). Compared with patients without, ECV was significantly increased in patients with one or more complications (29.0 ± 3.3%, P = 0.02). Both in univariable analysis and after multivariable adjustment, ischemic heart disease, autonomic neuropathy, and active smoking were associated with increased levels of ECV. Active smoking exhibited the largest effect size (β = 2.0 percentage points, 95% CI 0.7–3.3). Former smokers ECV similar to that of never smokers. Albuminuria and systolic blood pressure were inversely associated with ECV in multivariable analysis, but after adjustment for medication suspected to affect ECV, the association with albuminuria was no longer significant (P = 0.1). Sodium–glucose cotransporter 2 inhibitor treatment was not significantly associated with reduced ECV (−0.8%, 95% CI −1.7 to 0.06, P = 0.067).

CONCLUSIONS
Patients with complications of diabetes have increased ECV, not seen in patients without complications. Ischemic heart disease, autonomic neuropathy, and active but not former smoking were highly associated with increased ECV.

Heart rate variability, task load and perceived exertion associated with a long-distance military ski exercise: A pilot study
Authors: Chatterjee Tirthankar , Bhattacharyya Debojyoti , Yadav Angad , Pal Madhusudan 
Published: October 2022

Objectives:
Skiing is practiced by the security forces posted at mountain areas for patrolling, securing borders, taking up rescue missions and sometimes as recreational activities. A study was planned to assess physiological and mental stress of a military ski activity through the measurement of heart rate (HR) variability, task load and perceived exertion.

Materials and Methods:
Eleven healthy Indian soldiers, trained with skiing techniques, participated in a 15 km skiing with 22 kg equipment at a predetermined snowy mountainous track. Pre- and post-exercise HR and HR variability (HRV) were recorded (bio-harness, Zephyr, USA) and questionnaires, namely NASA task load index (NASA-TLX) and Borg’s rating of perceived exertion (RPE) scale, were filled after exercise. Time and frequency domain parameters such as HR, variations between successive RR intervals (RMSSD), standard deviation of RR (SDNN) and percentage value of NN50 (pNN50), low- and high-frequency bands (LF and HF %) and LF/HF ratio were derived using Kubios software. Student’s t (paired) test was applied to compare pre- and post-exercise HRV parameters and Pearson’s correlation was applied to observe interdependencies between HRV and subjective scores.

Results:
The findings depicted increase in post-exercise HR and decrease in overall HRV (both significant). Besides this, there was an increase in LF (significant) and LF/HF ratio (insignificant). Such response shows sympathetic dominance over parasympathetic domain of autonomic nervous system. The physical and mental stress experienced during the exercise was also expressed through high physical demand (79 out of 100) and high overall task load (total score – 77 out of 100) of the NASA-TLX and a moderately heavy RPE score (14 out of 20).

Conclusion:
The pre- and post-exercise differences in physiological variables ensured the presence of physical stress along with dominance of sympathetic nervous system. Overall task load was depicted with high subjective ratings. Carrying out skiing task in an environment infested with cold, wind chill, moderate hypoxia at a snowy and mountainous track possibly has induced the observed physiological and mental stress to the participants. Such findings are important to understand exact requirements of the mountain warfare events carried out by the forces.

Authors: Seetharam Smitha Pernaje , MS Vinutha Shankar , Udupa Kaviraja , Reddy Niranjan , A Raveesha 
Published: October 2022

Objectives:
Heart rate variability (HRV) is the beat-to-beat variation of heart rate and an important non-invasive tool to study the cardiac autonomic nervous system activity. Ischaemic heart disease (IHD) patients are often considered to have a state of sympathetic predominance. Elimination of myocardial ischaemia with percutaneous coronary intervention (PCI) could restore autonomic balance. Hence, this study aimed to evaluate HRV measures, after successful revascularisation among IHD patients.

Materials and Methods:
A total of 145 male IHD patients planned for coronary angiography were recruited. Fifteen minutes of electrocardiogram recording was done. Short-term HRV analyses of all the patients were acquired and time-domain indices (standard deviation of normal-to-normal intervals [SDNN], root-mean-squared differences of successive R-R intervals [rMSSD]) and frequency-domain indices (low-frequency [LF] power, high-frequency [HF] power and total power [TP]) were analysed. Before and after PCI, all measurements were made.

Results:
This study included 145 male IHD patients with the mean age of 54.57 ± 10.81 years. There was a significant decrease in SDNN, rMSSD, LF, HF and TP whereas increase in LF/HF ratio following revascularisation. These changes in measures of neurocardiac regulation correlated with risk factors and medication on regression analysis.

Conclusion:
Increase in LF/HF ratio with the decrease in SDNN, rMSSD, LF, HF and TP in patients with IHD who underwent coronary intervention infers changed cardiac autonomic balance with this surgical procedure. These measures could be potentially used as prognostic measures in the future studies.
The Role of Inertinite Characteristics and Coal Porosity of Seam A-1 of Muara Enim Formation in West Merapi, Lahat, South Sumatera, Indonesia

Published: October 2022

Coal contains a complex network of nano-, meso-, and a macro-pore can store fluids and allow fluids to flow through it. Nanoporosity in coal is primarily a result of molecules that have aromatic molecular structures and have been preserved in coal. Most adsorbate compounds, including gases, are stored here. The study area is located in South Sumatera, West Merapi Area, Lahat Regency. Geologically, the area in South Sumatra Basin belongs to the Middle-Late Miocene Muara Enim Formation. Using the ply-by-ply method, coal samples were taken directly from Seam-A in the coal mine walls outcrop, based on macroscopically determinable lithotype information. During laboratory analyses, coal is microscopically analyzed to determine the amount of porosity, permeability, and vitrinite reflectance. The purpose of this study is to investigate the change in composition and characteristics of inertinite macerals when the porosity value is varied.. Vitrinite content is between 91.00-92.80 %; liptinite 0.90-3.40%; inertinite 3.70-4.80%; mineral matter 0.7%-1.8%. Withh a vitrinite reflectance average of 0.34-0.36%, the variation in composition is an indication of changes in plant communities or coal facies. It is generally classified as sub-bituminous coal (ASTM). Porosity value of seam A upper is 1.9% and seam A lower 1.51%, permeability value seam A upper is 70.1 mD and seam A lower 27.1%. Composition of mineral matter in seam A upper is 0.8% and seam A lower 1.7%. The increasing number of inertinite pore is followed by lower porosity value. The inertinite maceral is predominantly aromatic with a high level of cross-linking, and exhibits a high level of aromatization and condensation. They have the highest carbon and the lowest oxygen hydrogen content. A coal maceral's porosity is composed of void spaces, such as open cell lumens preserved in semifusinite and sclerotinite. The porosity of cleats is the percentage of volume in relation to volume of coal, and the porosity of permeability. In coal, semifusinite has extensive interconnected pores that can form significant conduits for fluid flow.
La Covid 19 à Dakar (Sénégal). Entre mesures sanitaires, vécu quotidien, traitement médiatique et psychose
Authors: Diagne Ndiouga 
Published: October 2022

La Covid 19 est apparue comme l’une des pandémies les plus virulentes de l’histoire de l’humanité. Comme « une temporalité de surprise », elle s’est érigée en maître. Elle a aussi fait naitre une peur et a entrainé une psychose sans précédent auprès des populations. Au Sénégal, son apparition a amené l’État à prendre plusieurs mesures sanitaires qui ont engendré des répercussions dans le vécu quotidien et collectif de la population. Son traitement médiatique a mobilisé tous les segments de la société. Entre état d’urgence, mesure sanitaire, couvre-feu, les séquelles de cette maladie ont amené à une modification des habitudes quotidiennes de la population sénégalaise. Ce texte est le fruit de réflexions d’un confiné errant. Il décrit et analyse à la fois les mesures sanitaires prises par l’État du Sénégal face à la Covid 19, les discours « covidiaires » nés de cette situation, le vécu quotidien d’un confiné ainsi que les leçons que nous pouvons tirer d’un contexte marqué par la peur et la psychose et nous amène à réfléchir sur le traitement médiatique autour de cette maladie dans le dénouement de ce pêle-mêle.
Водне питання як каталізатор конфліктогенності пакистансько-індійських відносин: еволюція та сучасний стан
Authors: Tykhonenko Iryna , Shurkova Oryna 
Published: October 2022

У статті здійснено спробу аналізу водного питання у відносинах між Пакистаном та Індією, яке все більше стає детермінантою конфліктогенності між державами з огляду на низку причин. По-перше, зростання потреб у воді зважаючи на економічний та соціальний виміри розвитку обох держав. По-друге, маніпулювання водним питанням у системі двосторонньої взаємодії щодо врегулювання проблеми Кашміру та погрози індійської сторони перекрити доступ Пакистану до води. По-третє, потреба у перегляді умов Договору про розподіл вод річки Інд 1960 р. зважаючи на розвиток мережі гідроелектростанцій Індією та Пакистаном та неефективність інституційного механізму посередництва зі сторони Світового банку. Автори дійшли висновку, що питання розподілу водних ресурсів все більше узалежнюється від діаметрально протилежних підходів Індії та Пакистану до існуючих протиріч та стає поряд з ядерним чинником ще одним фактором уповільненої дії до дестабілізації безпекового середовища у Південноазійському регіоні.
Європейська інтеграція Північної Македонії: виклики ХХІ ст.
Authors: Kravchenko Dmytro 
Published: October 2022

У статті увага зосереджена на дослідженні та аналізі міжнародної ситуації, що складалася навколо Республіки Македонія на її шляху до вступу до Європейського Союзу. Показано, як процес визнання Республіки Македонія Європейським Союзом ускладнювався внаслідок суперечностей між країнами-членами ЄС та Республікою Македонія. А саме суперечки з Грецією щодо назви держави, громадянства та елементів державної символіки Республіки Македонія, що розпочались на початку 1990-х рр., призвели до накладання Грецією вето на переговорний процес вступу Республіки Македонія до ЄС та НАТО, яке блокувало переговорний процес з 2008 по 2018 рр. А також історико-лінгвістичні протиріччя з Болгарією та її відмова затвердити переговорну структуру Європейського Союзу щодо Північної Македонії 17 листопада 2020 р., що тривала до липня 2022 року. Звертається увага, що події на європейському рівні вплинули на і без того повільний процес вступу країни до Європейського Союзу. 2019 рік став роком європейських виборів, включаючи вибори до Європейського парламенту, призначення та реструктуризацію Європейської комісії, а також затягнуту проблему Brexit. А обговорення та прийняття вимог Франції щодо нової, складнішої методології вступу до ЄС відклало процес розгляду питання вступу до цієї організації нових членів ще на два роки. Офіційні переговори про вступ до ЄС з Північною Македонією, що розпочались 19 липня 2022 року є важливим фактором, що посилює безпеку та оборону Балкан, забезпечує стабільність регіону, відкриває нові перспективи для держави та громадян Північної Македонії.
Financial Development, Renewable Energy and Unemployment in North Africa
Authors: Tsaurai Kunofiwa 
Published: October 2022

Purpose: The study examined the nexus between financial sector development, renewable energy usage and unemployment (UNEMP) in North African countries. The complementarities between (1) financial development (FIN) and renewable energy usage and (2) economic growth and financial development, and their influence on unemployment was also investigated within the context of North African countries.
Design/Methodology/Approach: Panel data (1992-2019) analysis methods such as fixed effects, fully modified ordinary least squares (FMOLS) and pooled ordinary least squares (OLS) were used.
Findings: Financial sector development had a significant unemployment reduction influence. Complementarity variables were also noted to have significantly reduced unemployment.
Implications/Originality/Value: North African countries should therefore craft, develop and implement financial development, renewable energy usage (RENEW) and economic growth enhancement strategies and policies to increase job creation capacity.
“Tiempos que les tocaron vivir”. Un modo de leer la narrativa latinoamericana contemporánea
Authors: Sánchez María Teresa 
Published: October 2022

El trabajo: “Tiempos que les tocaron vivir”. Un modo de leer la narrativa latinoamericana contemporánea propone leer la nouvelle Llamadas de Ámsterdam de Juan Villoro desde el escenario de las narrativas que tratan las consecuencias de la globalización. En esos términos, a partir de la nouvelle, se establecen relaciones con características transversales de la crónica urbana dando cuenta de las posibilidades actuales de narrar la experiencia contemporánea.
Desde los conceptos de contemporaneidad y posmodernidad, relevando aportes y diálogos posibles con la antropología, se propone leer las relaciones personales en la fragmentación de las megaciudades y observar los modos en que la novela muestra una sociedad identificada por imaginarios urbanos.

Market traders buy and sell volatile assets frequently, with a goal to maximize their total return. There is usually a commission for each purchase and sale. Two such assets are gold and bitcoin. In order to solve the existing issues of purchases between gold and bitcoin, given that we have 1,000 USD, what strategies should we take to maximize our profits? In this article, the authors established seven models to predict the value of gold and bitcoins and how you should buy them, as the trends of value fluctuate, our models must be accurate enough to avoid being influenced. Targeted at that, the content is divided into three parts. For part 1: The authors selected several indicators that feature how the stock runs. For instance, price of gold and profit of gold to build first two models, which are the risk of investment model and the judgment on bull-or-bear market model. Then we use these models to evaluate whether it is safe to invest. The models are as follows: bear-bull market judgment model, risk of investment evaluation model, prediction model, trade model. For part 2: Based on the data concerned, the authors established the time series model to predict the way the market fluctuates. Meanwhile, the result of this model can be applied in correcting the results of former two models so as to make it more accurate. For part 3: The authors combined models above to give the best trading strategy. In addition, we improved the models by adding more indicators to make it more precise. We hope that by applying our models and strategies, you can successfully maximize your profit.

Primary CNS Lymphoma of Diffuse B cells in a Patient with Neurofibromatosis Type 1: A Case Report.
Authors: Ramirez-Loera Cristopher , Sandoval-Lopez Diego A. , Mejía-Pérez Sonia I. 
Published: October 2022

Objective: To describe the case of a patient diagnosed with Neurofibromatosis Type 1 (NF1), who developed her first neoplastic lesion as Primary Central Nervous System Lymphoma (PCNSL). To our knowledge, this is the third case of PCNSL in the context of NF1.
Background: PCNSL represents 1% of non-Hodgkin extranodal Lymphomas, and 3% of CNS tumors. Diffuse Large B-Cell Lymphoma accounts for 30-40% of the cases, commonly found in the encephalus, spinal cord, leptomeninges, or the eye. Predominant malignant tumors in NF1 are gliomas and Malignant Peripheral Nerve Sheath Tumor (MPNST).
Methods: A 53-year-old Mexican female, with a history of NF1, arrived at the emergency department with left-side subacute progressive numbness and weakness. Left hemiplegia. MRI showed a ring-enhancing lesion in the right central lobe and a lesion in the subcutaneous tissue. Additionally, the patient underwent a full body 18-FDG PET scan, which reported activity only in the CNS.
Results: Lesion-centered craniectomy and surgical evacuation were performed. Histopathological examination revealed lymphoid lineage cells, CD20, PAX-5, and Ki-67 were positive for neoplastic cells, confirming the diagnosis of PCNSL. At the 6-months follow-up visit, strength improved significantly, and the follow-up MRI did not show residual mass.
Conclusions: It is necessary to study the prevalence of LPSNC in these patients, as well as the relative risk, and to develop guidelines for its best approach. We believe that the real incidence of the disease is underestimated, since the genetic and pathophysiological mechanisms that promote its origin still need to be clarified.
