Authors: SMIRNOV Valerii V.
Published: February 2024

Subject. The article considers the debt economy of modern Russia.
Objectives. The purpose is to describe Russia’s debt-laden economy.
Methods. The study rests on systems approach, using the method of statistical analysis.
Results. The study identified necessary links in the Russian economy, i.e. international investment position, balance of payments, external debt, debt of the non-financial sector and households on bank loans and issued debt securities, contracts for the purchase of dollars and yuan with tomorrow next settlements in rubles, volume of government bonds of the Russian Federation. The paper establishes active growth of the international investment position of the Russian Federation, with increasing frequency of its negative growth rates, in the context of a decrease in the growth rate of the balance of payments in the dynamics of the activation of compensatory mechanisms aimed at combating its reduction. The paper also reveals an increase in the dynamics of the debt of the non-financial sector and households on bank loans and issued debt securities at average values of their growth rates. The main methods of securitization of Russian assets are the weakening of ruble exchange rate and support for State corporations.
Conclusions. The debt-based economy of modern Russia specifies opportunities for monetary authorities to replace foreign debt obligations and ensure the growth of the international investment position in a situation of declining balance of payments.

Published: February 2024

Profitability denotes a company's capacity to generate earnings within a specified timeframe. Companies that thrive and exhibit profitability are perceived as successful and typically garner favour among shareholders. This study examines profitability in the context of a company's ability to generate earnings within a specified timeframe, which is crucial for shareholder favour and business success. It focuses on the banking sector in Indonesia, encompassing 33 listed entities, with eight selected for the research sample. Employing hypothesis testing and analytical techniques, the study finds that asymmetric information and fluctuations in profitability do not affect credit pricing. Instead, credit risk positively impacts credit pricing, along with positive contributions from asymmetric information and profitability. This suggests that profitability does not hinder creditworthiness improvements. Asymmetric information does not affect credit pricing, making selling bank loans risky. Further research on credit pricing at a larger scale is warranted.

Teachers’ Beliefs : Kompetensi Emosional dan Sosialisasi Emosi pada Anak Usia Dini
Authors: Mafaza Mafaza , Sarry Septi Mayang
Published: February 2024

Teachers' beliefs about emotions can provide an overview of how teachers support the development of emotional competence in early childhood positively. This study aimed to investigate preschool teachers’ beliefs about emotional competence and emotion socialization. A sample of 194 preschool teachers from 22 Kindergartens completed the Teachers' Emotion Beliefs Scale (TEBS) and open questionnaires. The data were analyzed using descriptive statistical techniques and thematic analysis. The research results showed that 67% of teachers had developmentally appropriate beliefs, while 33% of teachers had beliefs that were not appropriate to children's emotional development. The developmentally appropriate belief explains the importance of the teacher's role in facilitating children's emotional competence. On the other hand, unappropriateness is explained by teachers' beliefs regarding children's expressions of negative emotions (such as sadness and anger), which according to teachers, young children do not need to express these emotions. Furthermore, the results of the open-ended questionnaire showed several teacher limitations regarding conceptual understanding of children's emotional competence, as well as in using appropriate strategies for emotional socialization (especially in helping children manage negative emotions). The way teachers socialize emotions is based on their beliefs regarding children's emotional competence.

Biodiesel production from hempseed (Cannabis sativa L.) oil: Providing optimum conditions by response surface methodology
Authors: Yazilitaş Cemal , Yilbaşi Zeki , Yeşilyurt Murat Kadir
Published: February 2024

This study focuses on the optimization of biodiesel synthesis using non-edible hempseed oil as the feedstock. The response surface method was used to find the best methanol: oil molar ratio, catalyst concentration, reaction temperature, and reaction duration for the transesterification process. The center composite design experimental design was used to make the design. A total of 30 cycles were conducted to adjust the four parameters at five different levels in order to optimize the biodiesel production process. It was found that the best conditions for transesterification of hempseed oil were a KOH catalyst concentration of 0.80 wt.%, a molar ratio of 7.41:1, a reaction time of 62.83 min, and a reaction temperature of 61.92 °C. Under these optimized reaction conditions, the predicted biodiesel yield was 95.57%, while the experimental yield was 95.24%. The biodiesel produced using the optimized parameters was analyzed for its properties, and the findings demonstrated that it met the requirements of EN 14214, a standard for biodiesel quality. The optimization of the biodiesel synthesis process using non-edible hempseed oil contributes to the exploration of alternative and sustainable feedstocks for biodiesel production. The values of the produced biodiesel within the standard range demonstrate its suitability for commercial applications and strengthen the potential of hemp seed oil as a suitable raw material for biodiesel production.
Towards a better comprehension of reactive transport coupling experimental and numerical approaches

Published: February 2024

In this work we focus on further understanding reactive transport in carbonate rocks, in particular limestones characterized by a bimodal pore size distribution. To this end, we performed injection experiments with CO2-saturated water on a sample of Euville limestone and monitored the experiments with a medical CT scanner. Microscanner imaging was performed before and after alteration. Experiments showed that permeability increased by nearly two decades due to the alteration process. This increase could be attributed to the formation of a preferential dissolution path visualized on the CT images. Microscanner images show that preferential dissolution areas are characterized by the presence of numerous enlarged macropores. The preferential dissolution path created therefore retains a porous structure and does not correspond to a wormhole-type channel. To provide further knowledge of the small-scale physics of reactive transport, we performed Lattice-Boltzmann simulations of flow in a numerically generated model 2D porous medium having geometrical and topological features designed to approach Euville limestone. We showed that the fluid velocity increased in nearly percolating paths of macropores. Considering the experiments, this means that the CO2-saturated water starts to enter high-velocity zones earlier than low-velocity zones, inducing an earlier onset of the alteration process and a more pronounced local dissolution. However, numerical results showed that the alteration of non-connected macropores leads to an increase of permeability much smaller than the experimentally observed one. To explain this fact we used effective medium modelling that permits predicting the variation in permeability as a function of the fraction of macropores and consequently as a function of alteration. It proved that as long as there is no alteration-induced percolating path consisting of macropores, the increase in permeability is relatively low as shown by the Lattice-Boltzmann simulations. An increase in permeability of several orders of magnitude is only observed when the macroporosity is close to the percolation threshold. This fact is in accordance with the experimentally observed results.

Genetic susceptibility to Tuberculosis in an infant with BCG-osis
Authors: Manwar Mansi Sahebrao , Gowri Vijaya , Taur Prasad , Iyengar Vaishnavi , Chougule Akshaya Sanjay , Desai Mukesh
Published: February 2024

Mendelian susceptibility to mycobacterial diseases (MSMD) is a group of innate immunity defects characterized by inborn susceptibility to intracellular pathogens. These are due to defects in the interleukin 12-23-interferon gamma y axis. Twenty-three genetic mutations have been identified in this axis, of which mutation in the IL12RB1 gene is the most common genetic defect of MSMD identified. An 11-month-old infant presented with features of axillary lymphadenitis and skin lesions both of which were positive for acid-fast bacilli on Ziehl– Neelsen stain and GeneXpert. Keeping a high index of suspicion of primary immunodeficiency, the child was evaluated further and was diagnosed as a case of MSMD with IL12RB1 gene mutation.

Authors: Shah Shalin , Nathani Prithvi , Aroojis Alaric , Agashe Mandar Vikas , Mehta Rujuta
Published: February 2024

Objectives:

Musculoskeletal manifestations of tuberculosis in infants are rare and different both in etiopathological mechanism and clinical presentation. Radiological diagnosis of osteoarticular tuberculosis (TB) in infants is tricky due to the various differentials of a cystic lesion. Literature also mention it only in isolated case reports. We carried out this study with an aim to collate and study patterns of osteoarticlular TB in the appendicular skeleton and to highlight the difficulties in diagnosis and management.

Material and Methods:

We retrospectively reviewed the data at our hospital over the past 8 years. Microbiologically confirmed osteoarticular tuberculosis affecting appendicular skeleton in children below 1 year of age were included in the study. Cases with spine involvement were excluded. The delay to diagnosis from the onset of symptoms, the initial diagnosis and treatment given were noted. The resolution of radiological presentation and occurrence of deformities at the final follow up (atleast 1 year) were noted.

Results:

During the study period, 8 infants were diagnosed to have osteoarticular tuberculosis with median age at presentation of 8.7 months (range 3 to 12 months). Average duration of follow up was 4 years (range 1 to 8 years). Cystic, Erosive, infiltrative, spina ventosa and mortar pestle were the radiological appearances found. Three of the 8 cases were referred as suspected malignancy. All but one case were vaccinated with BCG. Curettage and anti-tubercular therapy (ATT) were the treatment in all cases. Three cases with a delay in diagnosis of more than 2 months, developed complications: 1 had limb length discrepancy (LLD) due to physeal involvement, 1 developed angular deformity and 1 child had perthe’s disease as a sequelae.

Conclusion:

Osteoarticular tuberculosis is an increasing possibility, shockingly, even in infancy and should be a differential in an endemic country like India. A delay to diagnosis of even 2 months of this condition can lead to devastating complications. Being mindful of the diagnosis and early treatment gives rewarding results.
Fetal surgery for spina bifida – An upcoming standard of care
Authors: Ali Sheena , Deopujari Chandrashekhar , Andar Uday , Elbabaa Samer K.
Published: February 2024

Open spina bifida or myelomeningocele (MMC) is one of the most common serious congenital malformations that have been historically treated with a repair after birth. However, this “repair” does not avert neurological injury, reverse hindbrain herniation, or prevent hydrocephalus. With the intention to reduce numerous medical procedures, lifelong morbidities, and medical complications, fetal surgery was proposed about a quarter century ago. Fetal surgery has become the standard of care for MMC, especially after the advent of the Management of Myelomeningocele Study (MOMS) trial. Dr. Michael Harrison from the University of California was the first to birth this idea in the 1980s. While earlier research was carried out on ovine models, it was deduced that intrauterine repair reduces the secondary damage to exposed neural tissue and improves post-natal neurological outcomes. After the promising results in animal models and some clinical series, it paved the way for a prospective multicenter randomized controlled trial that compared prenatal versus postnatal MMC repair, with the aim to prove its efficacy and safety with Level-1 evidence- the MOMS. However, it was stopped early due to the improved prenatal repair outcomes, thus establishing open fetal MMC repair as the standard of care. We aim to discuss the origin story of this remarkable procedure, its rationales and advantages for the unborn child and mother and its short-term and long-term superiority and limitations. The operative procedure and the criteria with other essential aids in its diagnosis have also been discussed briefly. We also intend to eliminate the apprehension faced toward this procedure by the supporting team of obstetricians, anesthetists, neonatologists, and radiologists essential to making this procedure a success.
Knowledge, attitude, and practice towards neonatal palliative care of medical and nursing staff in an Indian context: A web-based survey
Authors: Singh Srijan , Mane Sushant Satish , Singh Srishti , Rai Rohit
Published: February 2024

Objectives:

Neonatal palliative care (NPC) is a holistic and interdisciplinary approach towards newborns with life-limiting conditions and encompasses their physical, psychosocial, and spiritual care and the redressal of pain. This study was designed to determine the knowledge, attitude, and practices towards NPC by the medical and nursing staff involved in neonatal care.

Material and Methods:

It was a questionnaire-based prospective cross-sectional study done at a tertiary care hospital in India by collecting data using the Neonatal Palliative Care Attitude Scale (NiPCAS) survey which has 26 attitudinal questions on a Likert scale.

Results:

There were 87 participants including 58 doctors (66.7%) and 29 (33.3%) nurses. Almost all of the respondents agreed that palliative care was necessary in neonatal nursing and medical education; but less than half had received education for the same. There was an overall agreement in the organization, resources, and clinician subscale by both medical and nursing respondents.

Conclusion:

There were similarities and differences in perceptions of NPC between medical and nursing staff. Several facilitators and barriers of NPC were identified. Efforts should be taken to strengthen facilitators while simultaneously mitigating barriers.

Published: February 2024

Background. Small-area burn is a common but specific type of injury that can still lead to serious complications if not managed properly. Researchers have introduced a number of interventions. Objective. The objective of this study was to compare the effects of eCASH concept-based care (ie, eBCare) with those of standard treatment on wound healing in patients with small-area burns. Methods. In this prospective randomized controlled trial, patients with small-area burns received either eBCare (n = 35) or standard burn treatment (n = 35) for 2 weeks. Pain, anxiety, heart rate, exudate, and wound area were measured during and after dressing changes. Scar color and thickness were assessed 4 years or longer after discharge. Results. The eBCare group had a lower median pain score, anxiety score, and heart rate compared with the control group (P < .001). The eBCare group also had a higher median wound healing rate on day 14 than the control group (P < .05). At follow-up 4 years or more after discharge, the eBCare group had better scar color and thickness than the control group (P < .05). Conclusion. The use of eBCare reduced pain and anxiety, accelerated wound healing, and improved scar outcomes in patients with small-area burns, which suggests that eBCare may be a feasible option for this population.

Background. The long-term chronic effect of radiotherapy is commonly referred to as LRTI. Clinical complications such as skin atrophy, tissue fibrosis, endothelial damage, ulcer formation, and compromised wound healing are common sequela. Despite advances in medicine over the past decade, there remains a need for effective treatments for LRTI skin necrosis and ulcerations. Materials and Methods. This case series discusses cTOT in 3 patients of advanced age with LRTI wounds having undergone Mohs surgery. All wounds had been recalcitrant to multiple wound care treatments. All patients suffered with significant wound pain as well. Results. cTOT resulted in complete wound healing in all 3 patient cases. Additionally, all 3 patients reported a significant reduction in wound pain during the course of therapy. Conclusions. The positive outcomes exhibited in this case series suggest that cTOT is an effective treatment in the management of Mohs surgery patients with compromised wound healing due to radiation, advanced age, and comorbidities.

Penyakit degeneratif merupakan penyakit kronik yang mempengaruhi kualitas hidup serta produktivitas seseorang. Penyakit degeneratif antara lain hipertensi, asma, kanker, diabetes mellitus, osteoporosis dan sebagainya. Masalah kesehatan Indonesia saat ini dipengaruhi oleh pola hidup, lingkungan kerja, dan stress. Tujuan penelitian untuk mengetahui perbedaan hasil pemeriksaan laboratorium profil kimia darah (kadar gula darah, kolesterol, asam urat, kreatinin, ureum dan SGOT) pada usia produktif di Wilayah Kerja Puskesmas Kota Jambi tahun 2022. Metode Penelitian cross sectional dengan populasi adalah masyarakat di Posbindu pada wilayah kerja 3 Puskesmas (KONI, Pakuan baru dan Putri Ayu) dengan tekhnik purposive sampling, dimana sampel penelitian adalah kelompok Posbindu yang berumur produktif (16-64 tahun) yang berjumlah 140 responden. Data di analisis menggunakan uji independent t­-test. Hasil penelitian dari 140 responden terdapat 71 (50.7%) orang jenis kelamin laki-laki, 53 orang (37.9%) dengan indek masa tubuh (IMT) obesitas, dan 43 orang (30.7%) memiliki tekanan darah tinggi. Hasil pemeriksaan laboratorium terhadap kadar profil kimia darah, kadar yang tinggi yaitu 25% kadar gula darah prediabetes dan 10.7% diabetes. Kolesterol 30%, asam urat 20.7%, kreatinin 4.3%, ureum 6,4% dan SGOT 10%. Kesimpulan ada perbedaan bermakna antara rata-rata kadar (gula darah, kolesterol, kreatinin, ureum dan SGOT) pada kelompok usia produktif dengan tekanan darah. Sedangkan kadar asam urat tidak ada perbedaan yang bermakna. Saran bagi masyarakat, diharapkan lebih memperhatikan kondisi kesehatan dengan rutin melakukam Medical Check Up untuk meminimalisir terjadinya penyakit degeneratif pada usia produktif.

Pada tahun 2021, Puskesmas Pamarican memiliki kasus TB paru tertinggi kedua di Kabupaten Ciamis. Tujuan penelitian adalah menganalisis faktor determinan kasus TB paru di wilayah kerja Puskesmas Pamarican. Penelitian ini menggunakan desain kasus kontrol. Populasi kasus adalah semua pasien di Puskesmas Pamarican tahun 2021 hingga Juli tahun 2022 yang terkonfirmasi TB paru BTA (+) dan tinggal di wilayah kerja Puskesmas Pamarican yaitu 34 orang. Sedangkan kelompok kontrol adalah semua pasien di Puskesmas Pamarican tahun 2021 hingga Juli tahun 2022 yang dinyatakan negatif TB paru yaitu 416 orang. Sampel kasus ditentukan dengan teknik total sampling. Sedangkan, sampel kontrol ditentukan dengan teknik purposive sampling. 1 kasus berbanding dengan 2 kontrol sehingga besar sampel kasus sebanyak 34 orang dan sampel kontrol sebanyak 68 orang. Data dikumpulkan melalui wawancara menggunakan kuesioner, observasi menggunakan lembar observasi serta pengukuran langsung menggunakan rollmeter. Data dianalisis secara univariat, bivariat menggunakan uji chi square dan fisher exact, serta multivariat dengan regresi logistik ganda. Hasil analisis bivariat menunjukkan 2 variabel yang terbukti memiliki hubungan signifikan dengan kejadian TB paru yaitu status perkawinan (p = 0,038; OR = 2,774, 95% CI: 1,038-7,414), penyakit komorbid (p = 0,006; OR = 6,667; 95% CI: 1,640 – 27,107). Analisis multivariat menunjukkan hasil yaitu penyakit komorbid menjadi variabel yang paling berhubungan dengan TB paru, dimana OR sebesar 5,302 (95% CI: 1,215 – 23,146). Berdasarkan hasil penelitian, disarankan kepada Dinas Kesehatan/Puskesmas Pamarican untuk terus melakukan pemantauan dan pengendalian penyakit komorbid yaitu DM yang menjadi faktor risiko penularan TB.
