OBJECTIVE

Little is known about the impact of early attainment of tight glycemic control on long-term β-cell function and glycemic control in youth-onset type 2 diabetes. We examined the effect of the initial 6 months of glycemic control on β-cell function and glycemic control longitudinally over 9 years and the impact of sex, race/ethnicity, and BMI on these relationships in adolescents with youth-onset type 2 diabetes in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

RESEARCH DESIGN AND METHODS

Oral glucose tolerance tests were performed longitudinally through year 9 to derive estimates of insulin sensitivity and secretion. Early glycemia was defined by mean HbA1c during the first 6 months postrandomization, categorized into five HbA1c groups (<5.7%, 5.7 to <6.4%, 6.4 to <7.0%, 7.0 to <8.0%, and ≥8.0%). The long-term period was defined as the period between years 2 and 9.

RESULTS

A total of 656 participants (64.8% female, baseline mean age 14 years, diabetes duration <2 years) had longitudinal data available over an average of 6.4 ± 3.2 years of follow-up. HbA1c significantly increased in all early glycemic groups during years 2–9, with a steeper increase (+0.40%/year) among participants with the tightest initial control (mean early HbA1c <5.7%), in parallel to a decline in the C-peptide–derived disposition index. Nevertheless, the lower HbA1c categories continued to have relatively lower HbA1c over time.

CONCLUSIONS

Early tight glycemic control in the TODAY study was related to β-cell reserve and translated to better long-term glycemic control. However, tight early glycemic control on the randomized treatment in the TODAY study did not prevent deterioration of β-cell function.

Published: June 2023

Remimazolam, an ultra-short-acting benzodiazepine, is a new intravenous anesthetic used for sedation and general anesthesia. Because remimazolam is primarily metabolized by carboxylesterases in the liver and other tissues including the lung and has metabolites with little or no bioactivity, its anesthetic effect is not significantly influenced by renal dysfunction. Therefore, remimazolam may be considered an appropriate agent for hemodialysis patients and may have added benefits beyond midazolam and propofol. Remimazolam has also been suggested to cause less cardiac depression than propofol. This case report presents an 82-year-old female hemodialysis patient with chronic heart failure who underwent partial glossectomy for squamous cell carcinoma of the tongue under general anesthesia with remimazolam and remifentanil. Hemodynamic control was stable during the anesthetic, which was safely completed without any adverse events and resulted in a rapid, clear emergence without flumazenil. Remimazolam and remifentanil may be appropriate as first-line general anesthetic agents for hemodialysis patients with heart failure.

The work emphasizes the importance of maintaining a consistent temperature while transporting temperature-sensitive goods in the logistics cold chain. Refrigerated transportation plays a critical role in this chain, and the safe and efficient transport of perishable goods, such as food or pharmaceuticals, heavily relies on maintaining appropriate temperature levels. Real-time temperature monitoring and timely response to deviations are vital to prevent spoilage and financial losses. This paper presents an intelligent temperature monitoring system that employs a WiFi-enabled IoT platform NodeMCU-ESP32 to collect real-time temperature data, which is then transmitted to the AWS cloud platform. The system uses machine learning algorithms to predict temperature deviations and sends alerts to relevant stakeholders via the Telegram messaging service. The system architecture comprises AWS services, including API Gateway, IAM, Lambda, DynamoDB, and SNS, offering a scalable, secure, and cost-effective temperature monitoring solution.

Authors: Gürbüz Esra , Çelik Mehmet , Alkan Sevil , Karaayvaz Serhat
Published: June 2023

Aim: Chlamydia trachomatis, is one of the most important sexually transmitted disease (STD) pathogens on a global scale. In this study we aimed to analyze the publication developments with bibliometric methods on C.trachomatis by examining the research articles published between January 1970–December 2021.

Material and methods: Herein, a bibliometric design was used to achieve the developments in C. trachomatis research. Research articles published in the Web of Science (WoS) database between January, 1970–December, 2021 were included in the study. The keywords selected for the search were ‘Chlamydia trachomatis, Chlamydia, and C. trachomatis’.

Results: The search of the WoS database for C. trachomatis research articles from 1970 to 2021 yielded 8133 results. Of the documents, 5696 were articles. 95.769% were published in Science Citation Index Expanded (SCI-EXPANDED) indexed journals. Most were published in English (94.803%). The articles were mostly from the Infectious Diseases (33.251%) research area. Most of the articles were from the USA. About 51% of the studies had funding organizations, with the United States Department of Health and Human Services provided the most financial support. Most of the articles (n=346, 6.074%) were published in the Journal of Sexually Transmitted Diseases. Although the number of publications seems to be irregular, it has not fallen below 80 articles per year, especially since 1980. The articles were cited 147,672 times (25.93 times per article) and the H-index was 133.

Conclusion: STDs are still an important public health problem in almost all parts of the world. We have found that the number of published articles and citations to articles on C. trachomatis has increased rapidly, especially in recent years. However, although the number of publications in developed countries has increased, the number of publications in developing and underdeveloped countries is below the expected level. Since C. trachomatis is a global public health problem, countries with a lower number of publications should be supported financially.

Published: June 2023

Aim: Acute pancreatitis (AP) is a disease with inflammation, and patients present with severe acute upper abdominal pain in emergency departments. AP can result in higher mortality as its clinical severity increases. Therefore, in this study, we want to investigate the clinical utility of the systemic inflammation response index (SIRI) and systemic immune-inflammation index (SII) in showing the severity of AP.

Material and methods: Among the patients admitted to our emergency department between January 2020 and December 2022, 201 patients diagnosed with AP were included in the study. These patients were divided into two groups according to the severity of the disease as mild and severe AP (MAP and SAP). Demographic data and laboratory data of the patients (white blood cell count, such as SIRI, SII and C-reactive protein, SIRI, SII and C-reactive protein) were recorded. Differences between groups of AP patients divided according to disease severity were analyzed.

Results: 165 (82.1%) patients had MAP and 36 (17.9%) patients had SAP. 52.8% of the patients were male. The mean of the SAP group was significantly higher than the SII MAP group (3165.71±3058.42 vs.1043.31±849.15; p<0.001). In addition, SII levels were significantly higher in the SAP group compared to MAP (11.19±6.27 vs. 3.12±3.01; p<0.001). In regression analysis, CRP, SIRI and SII was found to be able to predict SAP in patients with AP.  The power of SIRI and SII were found to be higher in predicting SAP [AUC for SIRI: 0.890; [AUC for SII: 0.859].

Conclusion: High SII and SIRI are useful markers that can show the severity of AP.

Authors: Topcu Ramazan , Tutan Duygu , Kartal Bahadır , Özkan Murat Bulut , Şahin Fatih , Tutan Mehmet Berksun
Published: June 2023

Aim: In primary hyperparathyroidism patients, avoiding hypoparathyroidism and hypocalcemia after surgery is essential. We aimed to evaluate if the delta parathormone percent value (ΔPTH%) can identify patients with an increased risk of developing hypocalcemia after parathyroid surgery for primary hyperparathyroidism.

Material and methods: Eighty patients with parathyroid adenomas who underwent single parathyroidectomy were analyzed, and demographical data, preoperative, and postoperative laboratory data were collected were included in the study. Postoperative hypocalcemia was defined as a corrected calcium value below 8.5 mg/dL calculated from the blood values taken on the first postoperative day. The ΔPTH value was calculated by finding the difference between the preoperative PTH value and the postoperative PTH value, and the percentage of ΔPTH was calculated by dividing the ΔPTH value by the preoperative PTH (ΔPTH = Preoperative PTH – Postoperative PTH, and ΔPTH% = ΔPTH / Preoperative PTH).

Results: Postoperative hypocalcemia developed in 7.5% of the patients. Hypocalcemic patients had higher ΔPTH and ΔPTH% values. The selection of 130.95 ng/L as ΔPTH level cutoff level divided patients with and without postoperative hypocalcemia with 83.3% sensitivity and 62.2% specificity. As for ΔPTH%, a cut-off value of 71.4% had 100.0% sensitivity, 56.8% specificity, and a 16-fold increase in odds of postoperative hypocalcemia.

Conclusion: ΔPTH and ΔPTH% values are helpful predictors of postoperative hypocalcemia after parathyroidectomy and can be used as a guiding tool.

Authors: Mukhamedov Bahrambek , Koldarova Evelina , Kurbanov Obid
Published: June 2023

Pityriasis rubra pilaris is a rare chronic inflammatory papulo-squamous skin disease, the pathogenesis of which is still unclear. The pathological essence of the disease is associated with a violation of keratinization against the background of hyperactivity of keratinocytes with subsequent inflammation, as well as with vitamin A dysmetabolism and a weakening of the protein-binding fiction of the liver. Unfortunately, treatment is complex with inconsistent improvement from topical therapies, including emollients, keratolytics, corticosteroids, vitamin D analogs, and retinoids. We present a clinical case of the juvenile type of Devergie’s disease in a 3-year-old child, which was caused by poisoning.

Authors: Başkent Ahmet , Feratoğlu Fatih
Published: June 2023

Aim: We aimed to evaluate the effectiveness of the Modified Darn Repair (MDR) method performed in our clinic for Inguinal Hernia Repair (IHR) and to determine the postoperative complications and recurrence rates of this method.

Material and methods: The records of all patients who underwent IHR with MDR method in our clinic between January 2012 and December 2021 were obtained from the hospital database. Demographic characteristics of the patients, intraoperative findings, hospitalization and return to normal activities, postoperative complications and recurrence rates were retrospectively analyzed.

Results: A total of 892 patients aged between 18 and 85 with a male:female ratio of 14:1 were studied. Of 1011 elective IHRs, 773 were unilateral (right/left: 452/321) and 119 (119 right + 119 left) were bilateral.  Hernia types were 667 (66%) indirect, 273 (27%) direct, 71(7%) pantaloon (combined) hernias. All procedures were performed under spinal anesthesia. The mean duration of surgery was 35 (15-75) minutes, hospital stay was 1.1 (1-3) days, and return to normal activities was 12.8 (10-20) days. The postoperative complications were wound infection in 33 (3.26%) patients, hematoma in 11 (1.09%) patients, and abscess/seroma in 15 (1.48%) patients. In addition, suture material reaction developed in 1 (0,12%) patient. Recurrence was observed in 25 (2.4%) patients and no mortality was observed in any patient.

Conclusion: The goal of every surgeon is to have a non-recurring repair in IHR without leaving a foreign body in the patient. Despite the criticism, we believe that the MDR technique is a safe, effective and viable option.

Published: June 2023

This research aimed to determine the best liquid media for the propagation of weed pathogenic fungi, the duration of the fungus storage on the media, and their virulence on goatweed (Ageratum conyzoides). The research consisted of two stages, i.e., the propagation of weed pathogenic fungi in alternative liquid media using a factorial completely randomized design, with the first factor being the pathogenic weed fungus (Curvularia sp., Fusarium sp., and Chaetomium sp.) and the second one being the media (tempeh or tapioca liquid waste) with four replicates. Applications were carried out using a hand sprayer on the underside of weed leaves at a density of 106 conidia or cfu mL-1. Each weed was sprayed with 10 mL of the solution. Variables observed were conidia density, number of colonies, incubation period and symptoms, disease intensity, the area under the disease progress curve (AUDPC), plant height, number of leaves, dry crown weight, and dry root weight. The results showed that tempeh and tapioca liquid waste media could be used as alternative media for multiplying pathogenic fungi. The conidia density of Curvularia sp. was 2.375 × 109 conidia mL-1 higher than that of Fusarium sp. at 1.7 × 109 conidia mL-1 and Chaetomium sp. at 9.5×104 cfu mL-1. Curvularia sp. propagated in tempeh liquid waste was able to cause damage to the leaves of goatweed as shown successively from the incubation period of 3.33 dai or accelerating 81.50%, increasing the disease intensity of 88.78%, and the AUDPC of 713.25% days compared to control. The most effective shelf life of Curvularia sp., Fusarium sp., and Chaetomium sp. in both tempeh and tapioca liquid waste media was found at six weeks at room temperature. Curvularia sp. in tapioca liquid waste could decrease weed height, the number of leaves, shoot dry weight, and root dry weight by 45.11, 28.65, 22.12, and 46.25%, respectively, compared to control.

Role of innovations in strategic development of Russian industrial corporations
Authors: Izmaylova Marina Alekseevna , Veselovskiy Mikhail Yakovlevich
Published: June 2023

In modern conditions, the strategic development of Russian industrial corporations is unthinkable without their innovative activities that require an integrated approach to implementing all types of innovations. Successful innovations provide businesses with a significant advantage over the competitors by increasing the loyalty of consumers, business partners and investors, strengthening leadership in the industry, expanding market share and developing new markets, improving corporate image and financial performance. Among the problems in the innovation activities of the Russian companies there is mentioned the slow build-up of the resource base for innovation; growth of innovation activity below normal; noticeable lagging behind European countries in terms of the specific weight of domestic innovative products; low speed of innovative developments with a steady disregard for collaboration with external partners and the purchase of ready-made new technological solutions from third party companies. It has been found that the high cost of innovations and the lack of companies' own funds for their implementation have a restraining effect on the innovation activity. Analysis of the best innovative experience of companies allowed to identify the key success factors of innovation activities that should be taken into account in solving these problems. In the list of such factors are the development of its own innovative strategy with an ambitious goal setting; an integrated approach to the implementation of innovations and the maximum use by companies of their capabilities - from generating ideas to conducting systematic work with external business partners; providing innovation with the necessary resources and creating an organizational structure that ensures a more efficient organization of the innovation process; organizing an effective innovation management system in order to rationalize it; introducing a strong corporate culture and motivation system.

Published: June 2023

The article considers the main problems of spatial development of single-industry towns of the Russian Federation. The determining influence of modern economic uncertainty conditions on the interrelated processes of economic activity of single-industry enterprises and socio-economic development of single-industry municipalities has been established. The necessity to improve the management process in the sphere of ensuring the development of single-industry towns at the regional level has been proved. The creation of the Regional Monocities Development Fund is proposed. On the case of Perm Krai the key tasks and activities of regional funds for the development of single-industry towns are defined. The main provisions and concepts laid down in the basis of the activities of the formed Fund for the management of development of monocities in the Perm region have been defined. Organizational model for improving the management system of development of single-industry towns in the region has been developed, which allowed to graphically present the management system of the region, defining a new stage of economic monocities of Perm Krai in conditions of modern economic uncertainty. The distinction of the proposed model is the inclusion of procedures for decomposition of the factors of modern economic uncertainty and deformation of economic activities of single-industry towns, as well as feedback, which allows to promptly correct managerial actions to overcome the newly emerging problems. Three scenarios of development of Alexandrovsky, Ochersky and Chusovsky monotowns of Perm Krai using sectoral coefficients-deflators of spatial development of the Russian Federation for the period 2021-2025 and analytical comprehension of trends and indicators with the decomposition of factors of modern economic uncertainty are considered. The results obtained in the course of this work may be in demand and are recommended for use in the regional and municipal government of the Perm region, in the process of improving the management of development of single-industry towns.
Analysis of prospects for renewal of river tanker fleet under leasing and life-cycle contract conditions
Authors: Krasiuk Alla Borisovna , Butsanets Artem Aleksandrovich , Mordasova Arina Aleksandrovna
Published: June 2023

Today, a number of state programs are aimed at the development of water transport, in particular, financing the construction of new sea vessels and inland navigation. Leasing is a key financial mechanism for building ships at domestic shipyards. Currently, life cycle contracts are successfully used, a significant advantage of which is the coverage of all stages of the life cycle of an object: design, construction, operation and disposal of an object. The expediency of updating the fleet with the help of life cycle contracts, as well as the comparability of costs when using a life cycle contract and leasing, was noted. A tanker with a carrying capacity of 4,800 tons was chosen as a representative vessel comparable in terms of its technical and operational characteristics to the m/v Volgoneft project No. 1577 after its renovation in order to meet the requirements of the International Association of Classification Societies (IACS), which caused a decrease in carrying capacity compared to the design values. The results of calculations of the estimated cost of a representative vessel supervised by the Russian Classification Society (RCS) are presented, as well as an assessment of economic results for two main options for financing the acquisition of a vessel: leasing and a life cycle contract. The calculations were carried out according to the design version of the representative vessel for the entire period of its useful life. It should be noted that given the modernization of all tankers of the Volgoneft type, and not just their parts, the forecast for the retirement of vessels may be more optimistic, which does not make the issue of building a new fleet less urgent. The average annual costs for scheduled repairs were determined based on the experience of operating river bulk tankers taken as a prototype (in our case, these are the Volgoneft type vessels), with the frequency of scheduled repairs specified in the rules for repairing river fleet ships. In order to evaluate and compare the efficiency of operating a leased vessel from the position of the company, its operating, cash flows were calculated for the entire useful life of the vessel. It is concluded that the life cycle contract will allow the shipping company to accumulate more own funds in the early life of the facility compared to leasing, which makes it possible to direct them to finance the renewal of the company's tangible assets both for the acquisition of new ships and for the modernization of existing property.

Abstract
This research is qualitative research with a case study approach. This study aims to describe the level of students' problem-solving in fraction operations. The subjects of this study were three students of SDN 70 Manjalling who had low, moderate, and high abilities in solving fractions. Data were collected through written tests and individual interviews to obtain valid information. The results showed that students with high problem-solving abilities were able to apply all of Polya's problem-solving steps. Students with moderate problem-solving abilities could not do all of Polya's problem-solving steps. They only applied steps of understanding the problem and making a solution plan. Students with low abilities found it challenging to use fractions and were unable to use each step to solve the Polya's problem. Those students could only apply steps of understanding the problem and making a solution plan, but they did not understand the problem and could not convert it into mathematical forms.

Authors: Munadi Radhie , Kaslam Kaslam
Published: June 2023

Hutan merupakan kawasan di muka bumi yang memiliki peran yang sangat penting bagi manusia. Faktanya, telah terjadi kerusakan yang amat parah diakibatkan oleh ulah manusia dalam mengeksploitasi untuk memenuhi kebutuhannya. Dampak dari kerusakan hutan multidimensi bagi keberlangsungan hidup di bumi. Tulisan ini mengkaji nash - nash yang terdapat dalam Al Qur’an terkait etika dalam pengelolaan hutan. Dengan menggunakan metode tafsir tematik, Al Qur’an banyak menyinggung tentang pengelolaan lingkungan hidup khususnya hutan. Peran manusia sebagai khalifatul ardh, menisbatkan pengelolaan lingkungan hidup yang bertanggung jawab. Konsep kekhalifahan bersifat transenden yang mengamanahkan pengelolaan hutan kepada manusia dan kelak akan dimintai pertanggungjawaban. Oleh karena itu hutan harus dikelola dengan baik, tidak melakukan pengrusakan dan eksploitasi yang berlebihan serta mempertahankan habitat asli atau melakukan konservasi terhadap hutan yang telah rusak. Dengan demikian, hutan dapat terjaga dan lestari sebagai warisan kepada generasi selanjutnya.
Tafsir Qs. An-Nur 24:32 Tentang Anjuran Menikah (Studi Analisis Hermeneutika Ma’na Cum Maghza)
Authors: Herlena Winceh , Muads Hasri Muhammad
Published: June 2023

Pada era sekarang, modal bisa dikatakan sebagai syarat utama untuk membangun rumah tangga. Namun Al-Qur’an berkata lain, Al-Qur’an menyerukan untuk menikah meskipun dalam keadaan fakir. Hal ini tentu saja mengalami kontradiksi dengan konteks sekarang yang mengharuskan modal sebelum pernikahan. Oleh karena itu, tulisan ini bertujuan untuk menggali lebih lanjut anjuran menikah dalam QS. An-Nur 24:32 dengan beberapa pertanyaan. Apa maksud dan tujuan QS. An-Nur 24:32 memerintahkan menikah meskipun dalam keadaan fakir?, kemudian bagaimana signifikansi dari QS. An-Nur 24:32 diimplementasikan dalam konteks sekarang?. Untuk menjawab rumusan masalah di atas, penelitian ini akan menggunakan teori hermeneutika ma’na cum maghza yang dipopulerkan oleh Sahiron Syamsuddin. Dari penelitian yang dilakukan, maka dapat disimpulkan bahwa anjuran menikah dalam keadaan fakir bukanlah maksud dan tujuan utama dari QS. An-Nur 24:32, melainkan sebagai pembebas bagi para budak dan hamba sahaya, anjuran untuk lebih menghargai orang-orang yang tidak mampu, serta anjuran menikah bagi yang telah mampu.

According to the interview results, students of SMK Muhammadiyah 2 Bontoala Makassar have good mathematical problem-solving skills. However, some students still find it difficult to solve math issues in the form of non-routine questions. According to other research, learning styles, notably kinesthetic learning styles, have a considerable impact on students' ability to solve mathematical problems. This study aims to describe the profile of students' mathematical problem-solving abilities based on Polya's theory (understand, strategy, solve and look back) in terms of kinesthetic learning styles. This type of research is descriptive qualitative research, and the data collection techniques in this study used three ways, namely filling out questionnaires, giving tests, and interviews. From the data collection techniques, the results obtained that two (2) students with kinesthetic learning styles have high problem-solving scores with an average of 77.5 and only fulfill three stages of problem-solving based on Polya's theory. Therefore, the teacher must pay attention to the tendency of kinesthetic learning styles in order to be able to improve students' mathematical problem-solving abilities.
