The Impact of the Increment and Production Relationship on the Species Composition Change in Türkiye's Natural Forests
Authors: Çalışkan Hüseyin , Özden Sezgin
Published: December 2024

Aim of study: Forest species composition changes might be caused by both natural processes and human-related factors. The aim of this study is to examine the effect of the balance between annual increment and production of Türkiye's forests on species composition change.
Area of study: The study area is Türkiye that experienced a change of the balance of natural species composition in the last 10 years.
Material and method: The methodology employed in this study involved the collection and analysis of comprehensive data from multiple reliable sources. Statistical information was systematically gathered from Statistics of the General Directorate of Forestry of Türkiye (GDF).
Main results: Our analysis shows that Fagus and Pinus species have the fastest increasing timber production rate. Additionally, coniferous species are being replaced by non-coniferous species. This situation shows the concerns about transition to different types due to economic reasons and it raises concerns about the disruption of the current species composition.
Research highlights: The excessive demand for wood raw materials and production policies have an impact on the species composition change. Findings show a decrease in 3 of the 6 most widespread species in Türkiye's forests, which consist of 91.3% of the country’s forest area.

Measuring coral reflectance and calculating NDVI as a proxy for chlorophyll a with the DIVING-PAM-II v1
Authors: Watty Kay , Schoepf Verena , van der Zande Rene
Published: December 2024

Reflectance measurements have been widely used in remote sensing and visual ecology work to quantify the color of surfaces and organisms objectively. The Normalized Difference Vegetation Index (NDVI) is an established method to estimate chlorophyll a (Chl a) content in various organisms and ecosystems. It is based on the spectral properties of Chl a and the reflectance it causes in the red and near-infrared spectrum. The DIVING-PAM-II from Walz GmbH comes with a spectrometer (MINI-SPEC). It allows for spectral measurements in the range of 400 – 850 nm. This range is suitable for quantifying coral reflectance and subsequently calculating the NDVI. Estimating Chl a content non-invasively allows for continuous high-resolution monitoring of signs of bleaching and pigment loss during laboratory experiments or in the field. This protocol explains how to use the DIVING-PAM-II spectrometer to obtain coral reflectance measurements and calculate the NDVI as a proxy for Chl a.
Political Effects of Epidemic Psychology (the Case of the COVID-19)
Authors: Arsentyeva I.I.
Published: December 2024

The COVID-19 pandemic has impacted not only public health, economics, and politics, but also has had profound psychological effects, which in turn affect all spheres of life of individual states and the international community as a whole. To explore this impact, the article uses a model of epidemic psychology developed by British medical sociologist Philip Strong at the turn of the 1990s. Based on the history of epidemics, he identified patterns of changes in society during outbreaks of previously unknown infectious diseases. In his opinion, at least three types of psycho-social epidemics are spreading in parallel with a disease, developing according to their own laws, and affecting both individuals and society as a whole. The first of these is an epidemic of fear, the second is an epidemic of explanation and moralization and the third is an epidemic of action or proposed action. They not only present a threat to public order but also can powerfully influence the size, timing, and shape of the social and political response in many other areas affected by the epidemic. The COVID-19 pandemic has revealed many vulnerabilities in people’s response to a sudden outbreak of a new disease, which poses a serious threat to security at both the national and global levels. Understanding the causes of such a response and identifying patterns of development of epidemics/pandemics play an important role in the fight against them. In this regard, the purpose of the article is to verify the relevance of Strong’s model for the analysis of the COVID-19 pandemic. This purpose dictates the structure of the study, which outlines the British scientist’s key concepts and applies his model to the situation with COVID-19 in general and in the field of politics. Since COVID-19 is the first pandemic in the era of social media, special attention is paid to the information epidemic (infodemic). The final part of the article highlights some of the effects of epidemic psychology in the context of humanity’s predicted entry into an “era of pandemics”. Promising directions for further research on the issue are outlined.

Authors: Ge Jian , Zhou Di , Zhuang Xiao , Wang Xiaomin , Xiang Jiawei
Published: December 2024

To address the issues of low data quality and poor adaptability in deep learning methods for infrared image analysis in gearbox fault diagnosis, this paper introduces an enhanced deep prototype network model (MSPNet). This model employs a multi-scale strategy to improve fault diagnosis accuracy and algorithm generalization, especially with small sample sizes. First, infrared image data of six fault types under five operating conditions are collected using a rotating test bed. Gaussian noise is added to simulate real operating conditions. Next, the fault data are processed using a multiscale module to extract multiscale fault features and reduce feature value fluctuations. Finally, the proposed model is used to process the image data and is experimentally compared with five other algorithms. The experimental results demonstrate that the proposed method outperforms the other algorithms under various operating conditions.

Published: December 2024

Antes de que se presentara la pandemia del Covid -19, había una serie de voces que cuestionaban el quehacer cotidiano de las escuelas, Entonces llegó la pandemia, cerrando las aulas físicas y cimbrando todas las certezas existentes. Mirando esta situación en retrospectiva nos preguntamos: ¿Qué hemos aprendido en el ámbito educativo después de estas experiencias? ¿Qué perfil de docente se hizo necesario favorecer? ¿Las instituciones formadoras de docentes hemos cambiado nuestras prácticas a partir de los aprendizajes que la contingencia sanitaria nos enseñó? La presente investigación busca aportar ideas hacia estas preguntas, teniendo dos objetivos generales: identificar los rasgos y saberes que deben de incorporarse en los perfiles de egreso en la formación de docentes en México y conocer la propuesta de acciones que las instituciones formadoras de docentes señalan como necesarias para el logro de los rasgos y saberes que se están priorizando. Se realiza una investigación en la Escuela Normal Superior de Michoacán donde participan docentes de la misma, normalistas y maestros recién egresados. Se utiliza la triangulación de técnicas y la triangulación de informantes con instrumentos como las narrativas, encuestas y entrevistas. Entre los hallazgos destaca una tendencia a favorecer la interdisciplinariedad -en lugar de solo las disciplinas-, el desarrollo de habilidades de pensamiento crítico, uso de tecnologías, así como una visión más integral del docente y sus estudiantes.

Background: We evaluated the effectiveness and safety of appetite-stimulating syrup (AST) for managing loss of appetite (LOA) due to acute or chronic illness in Indian children and adolescents.
Methods: This was a prospective, multicenter, single-arm, open-label, observational study. Pediatric patients aged ≥6 to ≤15 years, with LOA due to acute or chronic illness were prescribed AST containing multivitamins (vitamins B12, B3, and B6), lysine, and zinc at a dose of 5 ml BID along with standard-of-care for 14 days.
Results: In all, 380 patients with a mean (SD) age of 10.0 (2.4) years were enrolled. Mean (SD) duration of LOA symptoms was 1.7 (1.2) months. Overall, 79.6% of patients reported improved appetite on day 14. Correspondingly, 25.7% and 79.6% patients reported statistically significant improvement in food consumption on days 7 and 14, respectively. The mean (SD) no. of meals per day improved significantly (p<0.001) to 2.9 (0.7) on day 7 and to 3.6 (0.8) on day 14, compared to 2.5 (0.5) meals per day at baseline. Investigators ranked the effectiveness of AST from very good to excellent in 73.2% and good in 26.5% of patients. No severe treatment-emergent adverse events were reported.
Conclusions: Two weeks of treatment with AST showed clinically relevant improvements in appetite and increased food consumption in children and adolescents with LOA due to acute or chronic illness. The syrup was ranked good to excellent for efficacy by investigators. These findings suggest that AST containing multivitamins, lysine, and zinc is effective for treating LOA in children and adolescents without any significant safety concerns.

Lei Antiterrorismo
Authors: Ribeiro Andrey
Published: December 2024

Esse trabalho traz uma análise sobre o estabelecimento da lei antiterrorismo brasileira, olhando principalmente como o risco de repressão a movimentos sociais permeou esse processo e ainda se mantém presente. O repúdio ao terrorismo está presente na Constituição do Brasil desde 1988, no entanto, apesar de várias tentativas, um arcabouço jurídico voltado especificamente para este crime só veio a ser estabelecido em 2016. Nessas discussões um dos argumentos recorrentes foi o perigo que tal lei poderia representar para os movimentos sociais, já que abria brechas jurídicas para a criminalização da atuação desses grupos. Considerando essas discussões esse trabalho busca justamente olhar para esse processo, analisando os motivos para tal receio, como ele influenciou o bloqueio de uma lei deste tipo por tanto tempo e qual a situação desta discussão atualmente. Como fonte será utilizada principalmente a documentação referente a tramitação da proposta de lei, bem como fontes secundárias referentes aos bastidores políticos neste contexto.
extinção da SECADI como política de deseterritorialização de povos indígenas pelo Estado brasileiro (2016-2022)
Authors: Silva Maia Josué Felipe
Published: December 2024

A discussão ora proposta é parte de uma pesquisa mais ampla (em nível de doutoramento),em que temos discutido as relações entre Estado nacional brasileiro e povos indígenas. Desta vez, voltaremos nossa atenção, mais especificamente, para o uso de instituições do Estado, cujas políticas tendem a fragilizar a consolidação dos territórios indígenas. Nosso recorte empírico tem como foco a extinção da Secretaria de Educação Continuada, Alfabetização, Diversidade e Inclusão (SECADI) por um período que compreendeu os governos de Michel Temer e Jair Bolsonaro (2016-2022). Criada em 2004, no primeiro governo Lula, essa secretaria vinha desde 2009 desenvolvendo ações de criação e afirmação dos territórios etnoeducacionais. Um estudo do período em que esteve extinta será uma oportunidade de debate promissor em torno do tema de acesso das minorias nacionais ao reconhecimento e consolidação de seus modos de vida e ao desenvolvimento de ações para a promoção de educação inclusiva e educação ambiental com vistas à efetivação de políticas públicas intersetoriais.
Desenvolvimento, contestação e participação social na presidência brasileira do G20:
Authors: Santos Raquel , Rocha de Siqueira Isabel
Published: December 2024

Este artigo tem como objetivo introduzir um projeto de pesquisa sobre a participação social durante a presidência brasileira do G20. Apresentamos o G20 como uma plataforma alternativa que, ao mesmo tempo que é contestatória da atual estrutura da arquitetura financeira internacional, é contestada pela sociedade civil e movimentos sociais de seus Estados-membro. Partindo de uma abordagem crítica ao desenvolvimento, adotamos a noção deste como uma matriz discursiva que é co-constitutiva de mudanças sociais. Assim, propomos a discussão em cima da seguinte questão: quem e como os discursos encampados pelo G20 convocam ao engajamento a partir de seu formato de operação? Para tanto, seguiremos em três tópicos: a história improvisada do G20; uma discussão sobre os conceitos de ‘desenvolvimento’ e ‘contestação’ e suas correlações analíticas; e os modelos de participação social mobilizados a partir do G20, com foco no Civil20, na Cúpula dos Povos e no ‘G20 Social’.
Ativismo Judicial e a Luta Contra a Corrupção no Brasil
Authors: Petrarca Fernanda
Published: December 2024

Este artigo analisa os condicionantes sócio-históricos do ativismo judicial na chamada “luta contra a corrupção” no Brasil. Parte-se do princípio que para compreender essas condições é necessário, de um lado, levar em consideração a dinâmica do sistema de justiça nacional e a respectiva institucionalização da pauta anticorrupção. E, de outro lado, a forma de organização do sistema político. Como conclusão demonstrou-se que a fragmentação política constituiu uma das variáveis centrais que animou o processo de expansão do judiciário e sua independência e autonomia. A combinação entre a expansão institucional jurídica e a fragmentação política foi condição essencial para realização do ativismo judicial anticorrupção.
Efficacy of hyaluronic acid dermal filler for soft tissue augmentation around dental implants- A clinical study
Authors: Kaur Harleen , Kaur Gurpreet , Kaur Navneet
Published: December 2024

: The success of dental implant is based on direct contact between supporting alveolar bone and implants. Traditional surgical approaches to manage soft tissue discrepancies have shown initial good results, but virtually there is a significant reduction of tissue that may occur as soft tissue matures often. Minimally invasive procedures such as dermal fillers may be suitable alternative to correct soft tissue discrepancies.

: The aim of our study is to clinically evaluate efficacy of hyaluronic acid dermal filler for soft tissue augmentation around dental implants in Seibert’s class I/II ridges with minimal soft tissue deficiency.

: A total of 5 (1 female and 4 males) systematically healthy implant patients with single/ partially edentulous site in maxillary/mandibular region with minimal soft tissue deficiency were randomly selected and treated for soft tissue augmentation with 1% hyaluronic dermal filler. All the patients were evaluated for soft tissue parameters of soft tissue thickness, keratinized tissue width, papillary soft tissue horizontal width, papillary recession depth and papillary index score at baseline, 45th and 90th day after soft tissue augmentation.

At 45 day width of soft tissue (Mesial Papilla, Mid buccal point and distal papilla), Width of keratinized mucosa, soft tissue horizontal width (buccal and lingual point), papillary recession depth, showed statistically significant difference but no significant difference seen between 45 days and 90 days.

Injecting hyaluronic acid helped in improving various parameters but for a short period of time only.

Published: December 2024

Alveolar bone loss following tooth extraction is common. Socket preservation techniques, involving bone grafts and membranes, aim to mitigate this loss. This study evaluates the efficacy of a composite bone graft (bioglass and A-PRF gel) combined with A-PRF and collagen membranes for socket preservation, using Cone Beam Computed Tomography (CBCT) to assess dimensional changes over 6 months post-extraction. A case series of 5 patients requiring tooth extraction was included in the study. Clinical parameters, including plaque index, gingival bleeding, and keratinized tissue height, were recorded at baseline and six months. CBCT scans were performed immediately after extraction and at the six-month follow-up to measure crestal bone height and width. The results demonstrated a minimal decrease in crestal bone width (1.1 mm) and height (0.9 mm) at six months.The plaque index and gingival bleeding on probing remained stable throughout the study. The composite bone graft combined with A-PRF and collagen membranes offers an effective approach for minimizing alveolar bone loss and preserving ridge dimensions over six months, with promising implications for improving implant outcomes.
The Systemic Organization of the Operational Set of Thinking
Authors: Karpov Anatoly V.
Published: December 2024

The article presents materials of a theoretical, methodological and empirical-phenomenological nature, revealing and explaining the fundamental pattern of the organization of the most important cognitive process - the essence and structure of its operational set. It is shown that the basic mental operations, which are the operations of analysis and synthesis, abstract ion and concretization, comparison and generalization, reproduce in their content and com-position the most important principles and patterns, means and mechanisms of system organization. Because of this, there are homomorphism relations between the set of operations and the mechanisms of the system organization. The significance of this pattern also lies in the fact that it is thinking that largely represents and embodies the procedural content of the psyche as a whole and, consequently, itself.
The problem of cohabitation: motives, perception, dynamics
Authors: Bushkova-Shiklina Elvira V. , Ryabova Alisa S.
Published: December 2024

In the conditions of modern society, there is a transformation of the patterns and composition of marriage. A significant part of family and marital functions is realized in cohabitation relationships. A decrease in the demographic indicators of marriage, an increase in the illegitimate birth rate, as well as a change in the socio-cultural status of unregistered marriages actualize the study of cohabitation. The study of the motivation of cohabitation is becoming important in the context of Russia's policy to preserve traditional family values. Official statistics on the proportion and dynamics of cohabiting couples vary depending on the research methodology. According to the results of the author's survey of 400 people aged 18-55 years, as well as 14 in-depth interviews in cohabiting couples, it is shown that the attitude of the population towards cohabitation is quite loyal - 38 % of respondents support cohabitation, 63 % do not consider the current situation a crisis of the traditional family and the disintegration of family values. Cohabiting couples are poorly aware of the essence of civil marriage, confusing it with unregistered relationships, while clearly defining their advantages and limitations. There are differences in attitudes towards cohabitation in terms of age and gender. The authors conclude that cohabitation is considered as a transitional to marriage, as well as an alternative «legally facilitated» version of marital and family relations. Despite all the advantages, cohabitation is not considered as a full-fledged replacement for marriage and family, the need for cohabiting people to legitimize the relationship is quite pronounced, pregnancy and / or the birth of children becomes a good reason for this.
The potential of lifelong learning of senior citizens to fill the lack of human resources in the region
Authors: Vlasova Alexandra A. , Shamatonova Galina L.
Published: December 2024

The aging of the population is a common trend for economically developed countries, including Russia - every fourth resident of the country is at retirement age, which is 36.9 million people. The increase in the dependency burden on the economically active population, health and social care systems due to the aging of the population is becoming a new challenge for the modern economy. To activate income stream opportunities, it is necessary to bridge the gap between their competencies and the needs of the modern labor market. Lifelong learning is seen by additional people not only as a factor in their social development, reducing loneliness and improving cognitive function, but also as a key aspect of economic and economic development in the face of increasing labor shortages. Retraining and retraining of pensioners are the most relevant measures for their better inclusion in the modern labor market and compliance with the requirements of the post-industrial economy.
Migration strategies of the older population: the experience of Russia and other countries
Authors: Uriadova Anna V. , Akopova Tatiana S.
Published: December 2024

The article discusses migration strategies of the population over the working age in Russia and foreign countries. A comparative analysis of statistical data on the inbound and outbound flows of internal migration of this category of population in the Russian Federation has been performed. The features of regional differentiation of migration, as well as the intensity of migration of the population over the working age, are revealed. It is noted that the migration of the population over the working age is increasing numerically, but its share in the composition of migration flows remains stable. The internal migration of Russian pensioners is predominantly female in terms of its gender composition. Its main focus is migration movements between cities, whereas foreign pensioners mainly migrate from the city to the countryside. Among the causes of migration movements of people over the working age, special attention is paid to returning to their historical homeland and reuniting with their family. It is noted that family migration is typical for most European countries, and changes in migration strategies of the population over working age are associated not only with differences in the level and lifestyle of retirement in different countries, but also with the fact that the studied population category itself is changing qualitatively, it is becoming more adaptive and active.

Los terrenos agrícolas con pendientes pronunciadas no son utilizados durante todo el año, porque, el riego tradicional conduce a la baja velocidad de infiltración, erosión de suelos, escorrentía, perdida de los fertilizantes aplicados y baja eficiencia de riego. El objetivo fue evaluar el efecto de la pendiente de terreno y la disposición de tuberías terciarias sobre la uniformidad de riego y el rendimiento del cultivo de arveja. Se acondicionaron tres parcelas con pendientes de 10%, 20% y 40%; y en cada parcela se instalaron tres subunidades de riego, insertando 0, 2 y 6 válvulas manuales en las tuberías terciarias, teniendo un total de 09 tratamientos. Las parcelas se instalaron con cintas de riego de 1.6 l/h de descarga a 20cm entre goteros y a 60cm entre laterales. Los resultados del coeficiente de uniformidad (CU) con mayores valores fue para el T7 (Pendiente de terreno 40% con instalación de 6 válvulas en tubería terciaria) con un CU=96.30%; en el rendimiento de arveja el T3 (pendiente de terreno 10% con instalación de 2 válvulas en tubería terciaria) presentó 10.75 t/ha seguido del T1 (pendiente de terreno 10% sin instalación de válvulas en tubería terciaria) con 9.50 t/ha. Existe diferencia significativa entre los grupos para un p-valor < 0.05. La variación de la pendiente del terreno influye mínimamente en forma positiva sobre el CU y presenta una relación moderadamente negativa en el rendimiento. La disposición de válvulas manuales en tuberías terciarias influye positivamente en el CU y no influye en el rendimiento.

Con el propósito de dar valor agregado a la biomasa residual producida después del proceso de extracción de aceites a partir de microalgas, se desarrolló una metodología para obtener un hidrolizado proteico como fuente de aminoácidos esenciales que podría ser empleado como un ingrediente en la producción de piensos acuícolas. La metodología incluye etapas de cultivo de la microalga, extracción de clorofila, extracción de la proteína e hidrólisis de la proteína. Se obtuvieron 8 pruebas por duplicado en la extracción de proteína, en el cual el mejor rendimiento fue de 72,96 % a 45 °C y pH 13 por 120 minutos. Asimismo, en el hidrolizado proteico se realizaron 6 pruebas por duplicado empleando la enzima pepsina, donde el mayor grado de hidrólisis (21,98 %) se obtuvo a pH 3 y 37 °C, con una relación enzima sustrato de 2 %p por 4 horas. De acuerdo con los procesos con mayor rendimiento se realizó la caracterización y evaluación, a partir de la cual se concluyó que la metodología descrita para obtener el hidrolizado proteico fue exitosa al contar con la presencia de aminoácidos esenciales para la alimentación acuícola.
A multidimensional analysis of environmental awareness: The moderating effect of institutional trust
Authors: Dantas Diogo , Gomes Sofia
Published: December 2024

The research aims to examine global environmental awareness and recognises the need to employ four behavioural dimensions (affective, cognitive, dispositional, and active) into a structured model. We also include trust in institutions to understand its moderating effect on individuals' behaviour. The study used a broad sample from the ISSP in 29 countries and 44,400 individuals between October 2019 and May 2023. The quantitative model was tested with SmartPLS 4. All the hypotheses were confirmed. The affective dimension of environmental awareness positively affects its cognitive dimension. Both the affective and cognitive dimensions have a positive influence on the dispositional dimension. The dispositional dimension positively influences its active dimension. Trust in institutions positively moderates the relationship between the dispositional and active dimensions. Our research demonstrated that each person simultaneously acts as a change agent based on their perception of personal responsibility and as a consumer, a concept that managers strive to comprehend. Previous research was validated by establishing a causal link between different dimensions of behavior. Managers must focus on integrating the factors that influence pro-environmental behaviour. Governments are essential in changing mentalities and turning dispositional attitudes into effectively active behaviours.

Background: Brachial plexus block, particularly the supraclavicular approach. The choice of local anesthetic and the addition of adjuvants can significantly impact the quality and duration of the block. This study aimed to compare the effects of three different additives dexmedetomidine, dexamethasone, and sodium bicarbonate when combined with ropivacaine in ultrasound-guided supraclavicular blocks.
Methods: A double-blind randomized clinical trial was conducted with 103 patients undergoing upper limb orthopedic surgery. Patients were divided into four groups, and each group received one of the following combinations: ropivacaine with dexmedetomidine, ropivacaine with dexamethasone, ropivacaine with sodium bicarbonate, or ropivacaine alone (control). The onset and duration of motor and sensory blocks, complications, patient and surgeon satisfaction, and vital signs were assessed.
Results: The study revealed that all additives, particularly dexmedetomidine, significantly influenced the onset and duration of motor and sensory blocks compared to the control group. Dexmedetomidine demonstrated the fastest onset and prolonged the block, while dexamethasone and sodium bicarbonate also had substantial effects. Importantly, the additives did not lead to an increase in complications, and patient and surgeon satisfaction remained consistent across all groups.
Conclusion: The findings of this study suggest that dexmedetomidine is a promising adjuvant for enhancing the quality and duration of supraclavicular blocks.

Background: The laryngoscopy and tracheal intubation is a noxious stimuli resulting in transient but marked sympathetic response. This response is exaggerated in patients with hypertension. This study evaluated the role of oral pregabalin premedication in attenuation of haemodynamic response during tracheal intubation in adult patients with controlled hypertension posted for elective surgery.
Methods: A prospective double blinded randomized study was carried out in a total of 60 adult patients (aged 18-65 years, either gender) with controlled hypertension after being randomized into two groups with 30 patients in each. Prior to induction, Group PL received Placebo (multivitamin) and Group PB received pregabalin 75mg tablet 1 hour. The anaesthesia technique was standardized as per department protocols. Both groups were evaluated for pre-operative sedation, haemodynamic changes after premedication, before and after induction, after the laryngoscopy and tracheal intubation and post-operative side effects.
Results: There was attenuation of haemodynamic responses without significant side effects with pregabalin. Statistically significant increase in post intubation systolic, diastolic and mean blood pressure was seen in group PL as compared to group PB. In both groups, a reduction in heart rate was observed and was statistically significant 1 minute after intubation in group PB. Pre-operative sedation levels were higher in PB group in comparison to PL group. No post-operative side effects observed in both the groups.
Conclusion: In controlled hypertensive patients, oral pregabalin 75 mg attenuated the haemodynamic responses to laryngoscopy and tracheal intubation. It produced effective pre-operative sedation without any post-operative side effects.

Published: December 2024

Background: Blood glucose control during surgery can decrease the infection, disability, and death rate. The purpose of this study was to determine the effect of preoperative metformin on blood glucose levels in nondiabetic orthopedic surgery.
Methods: This clinical trial was conducted on 176 nondiabetic patients with ASA class I or II who were candidates for orthopedic surgery. The patients were randomly divided into two equal groups. The metformin group received 500 mg metformin tablet orally and the placebo group received placebo tablet 30 minutes before the surgery. Blood glucose was measured every 6-hour to 24 hours and blood urine nitrogen (BUN), creatinine was measured preoperatively and the day after surgery. The data was analyzed by SPSS v21 and P value<0.05 was significant.
Results: Demographic characteristics such as age, sex and body mass index (BMI) had no significant difference in two groups. Creatinine and BUN were similar in two groups. Preoperative blood glucose was 101.8±22.6 mg/dl in the metformin group and 109.7±24.8 mg/dl in the control group without significant difference (p=0.08). However, BS at hours 6, 12, showed a significant difference between the two groups (p<0.001, 0.022) and then blood glucose was similar in two groups (0.8, 0.12 respectively).
Conclusion: Preoperative metformin (500 mg) was effective for blood glucose control in nondiabetic patients undergoing orthopedic surgery. However, additional research is required to determine the efficacy of this therapy.
