The competitive calendars in sports often lead to fluctuations in the effort-recovery cycle and sleep quality. NESA noninvasive neuromodulation, achieved through microcurrent modulation of the autonomic nervous system, holds promise for enhancing sleep quality and autonomic activation during stressful situations. The objective of this study was to analyze the sleep and recovery responses of basketball players over six weeks of training and competition, with the integration of NESA noninvasive neuromodulation. A preliminary experimental study involving 12 participants was conducted, with a placebo group (n = 6) and an intervention group (n = 6) treated with NESA noninvasive neuromodulation. Sleep variables and biomarkers such as testosterone, cortisol, and the cortisol:testosterone ratio were analyzed to assess player recovery and adaptations. Significant differences were observed in total, duration, and REM sleep variables (p-value= < 0.001; 0.007; <0.001, respectively) between the intervention and placebo groups. The intervention group demonstrated increased duration of sleep variables. Cortisol levels showed normalization in the experimental group, particularly in the last two weeks coinciding with the start of playoffs. This study highlights the potential of NESA noninvasive neuromodulation to enhance sleep quality despite challenging circumstances, providing valuable insights into the management of athlete recovery in competitive sports settings.
Net-Zero Heroes? Climate Change Mitigation Efforts and Strategies across Australian Group-of-Eight Universities
Authors: Melville-Rea Kate , Arndt Stefan K.
Published: April 2024

Businesses are increasingly declaring their operations to be “carbon neutral” or “net-zero”. But how real are these claims? We investigated the climate mitigation efforts of the eight leading universities in Australia and discovered that the actual emission reductions lag behind the net-zero rhetoric. In the last ten years, most universities increased energy consumption, while reported emissions plateaued. The energy consumption and greenhouse gas emissions of Group-of-Eight (Go8) universities were influenced by size and population growth, climate of the campus location, and energy efficiencies. The Go8 universities experienced, on average, a 25% increase in student numbers in the last decade, and most increased their energy consumption. However, Scope 1 (direct emissions) and Scope 2 (emissions from electricity consumption) remained stable for most universities from 2011 to 2019 and decreased on a per-capita basis, indicating some level of improved efficiencies. Almost all Go8 universities have net-zero commitments and aim to achieve this by similar measures: power purchase agreements (PPAs) for electricity consumption, and carbon offsets for remaining emissions. Most universities lack a strategy for direct or measurable targets regarding energy or emissions reductions along their value chain. Unlike the UK or other countries, Australia has no standardised emission reporting requirements for Scope 3 emissions (other indirect emissions). This has led to rudimentary and haphazard reporting, limiting comparability between universities. Only one university had a more complete Scope 3 inventory, and these Scope 3 emissions were five times greater than their combined Scope 1 and 2 emissions, indicating a potential for substantial under-reporting of emissions. This highlights the need for more rigorous, consistent, and sector-specific emissions accounting, especially on indirect emissions, and for an overhaul of net-zero accreditation.

Published: April 2024

Soil fauna is responsible for one-quarter of all species on Earth, and these organisms play crucial roles in many ecosystem functions and services; however, these communities are facing several threats related to human activities, especially in the Cerrado ecoregion, the second largest biome. We aimed to evaluate the soil mesofauna communities in a native savanna (Cerrado) and two l eucalyptus stands to verify differences and infer possible impacts on soil mesofauna abundance and diversity through land-use changes, as well as find correlations between soil chemical parameters and soil mesofauna groups. Pitfall traps were installed in each one of the 12 plots per land-use type to evaluate soil mesofauna abundance and diversity in the dry and rainy seasons, and soil chemical analyses were performed at 0–20 and 20–40 cm depth per plot. We found that Collembola, Isoptera, and Diptera during the dry season collections, and Formicidae, Isoptera, and Diptera in the rainy season collection were more abundant in the Cerrado. The eucalyptus plantations have reduced the abundance of these groups, in addition to also representing a possible loss of biodiversity promoted by these monocultures. The organic matter, Potassium, Calcium, Phosphorous, and pH contents can be used as good soil mesofauna indicators in the Cerrado.

Published: April 2024

Coastal ecosystems form interconnected networks that are essential for the maintenance of marine biodiversity. This study investigates the dietary patterns of Apostichopus japonicus (sea cucumber) within a marine ranching ecosystem and reveals the influence of Zostera marina (seagrass) leaves from a distant bed on nutrient availability and trophic connectivity. Samples collected between September 2020 and March 2021 from Xiangyun Bay included A. japonicus, macroalgae, phytoplankton, and seagrass leaves. Stable isotope analysis (δ13C and δ15N), in conjunction with Bayesian mixing models, elucidated the contributions of different food sources to A. japonicus’ diet. Macroalgae constituted more than 50% of A. japonicus’ diet, while seagrass contributions ranged between 5.7% and 11.3%. The isotopic analysis confirmed the presence of seagrass debris in the marine ranching environment, indicating significant nutrient transport from a remote seagrass bed. This study underscores the crucial role played by macroalgae as the primary source of nutrients for A. japonicus within a marine ranching setting. Furthermore, detecting seagrass debris from a distant habitat highlights previously unrecognized ecological connectivity between seagrass ecosystems and artificial reef environments along coastal areas. This understanding of long-range nutrient transfers is vital for effective management and conservation strategies in coastal marine systems, emphasizing intricate yet significant ecological interdependencies across coastal environments.

This study analyzed the impact of weather variables on insect pest dynamics and their diversity in the radish ecosystem through field experiments conducted for two years at a locality in the eastern Himalayas. The relationship with weather variables was studied with six different dates of sowing, and diversity was assessed using standard indices. Various organic management options were also evaluated. Results revealed that temperature had a positive impact, whereas relative humidity and rainfall negatively affected the population of insect pests. The radish ecosystem harbors diverse insect species, including natural enemies, with higher species richness (4.8–5.2) and lower year-to-year variability. Organic management strategies such as neem oil, Beauveria bassiana, and Metarhizium robertsii demonstrated good efficacy against flea beetles without compromising yield, resulting in 39.76%, 39.39%, and 38.71% pest reduction over control, respectively. These biopesticides also recorded less than half to one-fourth reduction in natural predators like coccinellids compared to cypermethrin, a chemical pesticide (74%). The study suggests that, under projected climate change with higher temperatures, pest populations are assumed to increase. Considering the insect diversity of the eastern Himalayas, organic management strategies will be an adaptation strategy to conserve biodiversity while ensuring environment-friendly pest management.

Published: April 2024

The present work discusses the challenges and approaches involved in conserving cultural heritage (CH), specifically focusing on eco-friendly conservation methods and the management of biodeterioration. It highlights the need for innovative protocols that align with green conservation criteria, aiming to replace traditional, potentially harmful practices with sustainable alternatives. This study is based on the role of nanomaterials like halloysite in developing protective coatings for CH materials. Additionally, the issues of biological colonization on CH assets, the difficulties in controlling environmental factors affecting biodeterioration, and the use of direct methods in outdoor conservation were also evaluated. This work is specifically focused on a case study: the “Palazzo Centrale dell’ Università” in Catania (Italy), where alternative, eco-friendly protectives and biocides have been tested on Hyblean limestones. After a preliminary study of the lithology and the forms of degradation which affect the whole monument, laboratory tests were carried out using the newly developed protective coatings on several types of Hyblean limestone in order to assess their efficacy and their impact on the stone. Furthermore, cleaning operations were also tested on-site by comparing an eco-friendly biocide with commercial counterparts in order to evaluate the effectiveness of the products and establish an efficient restoration protocol for future projects.
Identifying Heterogeneous Willingness to Pay for New Energy Vehicles Attributes: A Discrete Choice Experiment in China
Authors: Han Haidi , Sun Shanxia
Published: April 2024

New energy vehicles (NEVs) have emerged as a promising solution to reduce carbon emissions and address environmental concerns in the transportation sector. In order to effectively accelerate market acceptance, it is crucial to prioritize the heterogeneity of consumer preferences for NEV attributes. This study employs the multinomial logit model (MNL) and latent class model (LCM) to investigate both observed and unobserved preference heterogeneity based on stated preferences obtained from a discrete choice experiment conducted across seven cities in China. Results from the MNL model indicate that all attributes significantly influence alternative utility. In particular, there are differences in the willingness to pay (WTP) for attributes of battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). Analysis of MNL subgroups reveals observed heterogeneity in WTP for identical attributes among consumers from regions with different latitudes and markets with different NEV penetration rates. Furthermore, the LCM model uncovers unobserved preference heterogeneity by classifying respondents into four distinct classes and identifies specific socioeconomic variables associated with each class. The recognition of heterogeneous WTP for NEV attributes across vehicle types, regions, markets, and consumer classes provides important implications for formulating targeted policies that promote the sustainable development of the NEV industry.
Does New Urbanization Support the Rural Inclusive Green Development under Domestic Circulation in China?
Authors: Hua Yuelei , Zhang Jize , Ding Xuhui , Ding Guoping
Published: April 2024

New urbanization is an endogenous driving force to enhance domestic circulation. Driving the development of rural industries with urbanization to achieve interactive symbiosis has become an important topic to promote the coordinated development of urban and rural green. Based on the panel data of 30 provinces in China from 2009 to 2021, this paper constructs an evaluation index system for new urbanization and rural inclusive green development, and uses principal component analysis and panel regression model to analyze the impact of new-type urbanization on inclusive green development in rural areas. The results of the study show the following: (1) Rural inclusive green development and new urbanization have been significantly improved during the study period, but there are significant regional differences. (2) The construction of the new urbanization significantly promotes rural inclusive green development, but there is significant spatial heterogeneity. This effect is more significant in the Eastern and Central regions. (3) Population urbanization, land urbanization, social urbanization, and environmental urbanization can effectively promote rural inclusive green development, but economic urbanization will have a negative impact on green development in the countryside during the study period. Therefore, it is necessary to further strengthen the leading role of central cities and urban agglomerations, to promote the countryside with the city and at the same time to combat environmental pollution and to create ecologically livable towns and villages. In addition, the government should strengthen top-level design, provide industrial support to backward areas, improve the spatial layout of urbanization, and promote the deepening of new urbanization.
The Impact of Consumer Environmental Preferences on the Green Technological Innovation of Chinese Listed Companies
Authors: Yu Ping , Zeng Linhui
Published: April 2024

Using the data of companies from heavily polluting industries listed on China’s A-share stock market from 2011 to 2022, this paper empirically investigates the impact of consumer environmental preference on green technological innovation. The results indicate that consumer environmental preference significantly promotes the green innovation of firms from heavily polluting industries. Moreover, consumer environmental preference imposes a higher influence on strategic green innovation than substantive green innovation. The mechanism tests suggest that consumer environmental preference encourages green technological innovation by strengthening the environmental protection concept and increasing R&D investment. Finally, we find that rising consumer environmental preference has a more prominent effect on the promotion of green innovation for enterprises in regions with higher levels of marketization and lower government environmental regulation, larger enterprises, and private enterprises.

Published: April 2024

This study examines the link between energy (using electricity generation as a proxy) and sustainable economic growth alongside the mediating role of salient socio-political factors, such as education, life expectancy, government effectiveness, and governance structure, among others, based on data about the Nigerian economy from 1980 to 2022. We employed a battery of econometric techniques, ranging from unit root tests to autoregressive distributed lag bound tests for cointegration and a modified version of the Granger causality test proposed by Dumitrescu and Hurlin. We also employed general-to-specific estimation techniques to examine the possibility of substituting renewable and non-renewable energy sources. Our results suggest a bi-directional Granger causality between electricity generation and sustainable economic growth. This supports the validity of the feedback hypothesis, suggesting that electricity and sustainable economic growth are interdependent. Our results further revealed that socio-political factors significantly impact electricity generation. The results of our general-to-specific estimation techniques suggest that no possibility of substitution exists between the two main energy sources in Nigeria. This has some key policy implications.

Published: April 2024

Trigeminal neuralgia (TN) is a chronic condition that is typically caused by a blood vessel exerting pressure on the V cranial nerve at the root entry zone. The gold standard for TN treatment is microvascular decompression (MVD). This illustrative case shows an advanced surgical technique that combines the use of an exoscope and endoscope to treat TN with an innovative addition of intraoperative indocyanine green (ICG) control that can improve arterial and venous compression identification. The use of exoscopes and endoscopes, offering 360° root assessment, represents a significant evolution in surgical approaches. Enhanced visualization with ICG aided in identifying complex neurovascular conflicts, improving decompression accuracy. The use of both exoscope and endoscope, offering a 360° root assessment, represents a significant evolution in the microsurgical approach of TN. The additional use of ICG monitoring in a dynamic mode may be useful in identifying the complex arteriovenous form of neurovascular conflict. The endoscopically assisted exoscopic surgery with the intraoperative use of ICG for MVD of the trigeminal nerve can improve the identification of complex impingements underlining its effectiveness and potential in neurosurgical practice.

Authors: Qiu Hongsheng , Wu Kaikun , Ayasrah Mo’men , Huang Weihong
Published: April 2024

Due to their excellent thermal conductivity and sensitivity to temperature changes, special attention should be paid to the influence of temperature on steel-structure bridges. The temperature effect is complex, especially for unstable steel arch bridges with complex structural forms. This paper proposes an approximate method that measures the three-dimensional temperature field of the symmetrical arch rib with the two-dimensional temperature field of multiple sections. In addition, it converts the complex radiant intensity calculation of the special-shaped steel box arch rib into the calculation of numerous planar radiant intensities. It uses the ANSYS Workbench to establish the three-dimensional transient thermal analysis finite element model of the No. 2 steel box arch rib. The influence of seasons and arch rib direction on the temperature field of steel box arch ribs and the stress and deformation of steel box arch ribs under non-linear temperature effects were analyzed. The results show that the temperature changes in different seasons significantly impact the temperature changes in the arch ribs. The change in the azimuth angle of the arch rib has a significant impact on the temperature difference between the web plates on both sides of the arch rib; under the influence of the temperature field at the most unfavorable time in summer and winter, symmetrical stress concentration occurs in the arch foot area. Furthermore, the maximum vertical displacement is 13.9 mm and 10.8 mm, respectively. Finally, when the angle is 40°, the maximum temperature difference between the web plates on both sides is 6.9 °C.
Bayesian Inference for the Gamma Zero-Truncated Poisson Distribution with an Application to Real Data
Authors: Srisuradetchai Patchanok , Niyomdecha Ausaina
Published: April 2024

This article presents Bayesian estimation methods applied to the gamma zero-truncated Poisson (GZTP) and the complementary gamma zero-truncated Poisson (CGZTP) distributions, encompassing both one-parameter and two-parameter models. These distributions are notably flexible and useful for modeling lifetime data. In the one-parameter model case, the Jeffreys prior is mathematically derived. The use of informative and noninformative priors, combined with the random walk Metropolis algorithm within a Bayesian framework, generates samples from the posterior distributions. Bayesian estimators’ effectiveness is examined through extensive simulation studies, in comparison with the maximum likelihood method. Results indicate that Bayesian estimators provide more precise parameter estimates, even with smaller sample sizes. Furthermore, the study and comparison of the coverage probabilities (CPs) and average lengths (ALs) of the credible intervals with those from Wald intervals suggest that Bayesian credible intervals typically yield shorter ALs and higher CPs, thereby demonstrating the effectiveness of Bayesian inference in the context of GZTP and CGZTP distributions. Lastly, Bayesian inference is applied to real data.
Neutrino at Different Epochs of the Friedmann Universe

Published: April 2024

At least two relics of the Big Bang have survived: the cosmological microwave background (CMB) and the cosmological neutrino background (CνB). Being the second most abundant particle in the universe, the neutrino has a significant impact on its evolution from the Big Bang to the present day. Neutrinos affect the following cosmological processes: the expansion rate of the universe, its chemical and isotopic composition, the CMB anisotropy and the formation of the large-scale structure of the universe. Another relic neutrino background is theoretically predicted, it consists of non-equilibrium antineutrinos of Primordial Nucleosynthesis arising as a result of the decay of neutrons and tritium nuclei. Such antineutrinos are an indicator of the baryon asymmetry of the universe. In addition to experimentally detectable active neutrinos, the existence of sterile neutrinos is theoretically predicted to generate neutrino masses and explain their oscillations. Sterile neutrinos can also solve such cosmological problems as the baryonic asymmetry of the universe and the nature of dark matter. The recent results of several independent experiments point to the possibility of the existence of a light sterile neutrino. However, the existence of such a neutrino is inconsistent with the predictions of the Standard Cosmological Model. The inclusion of a non-zero lepton asymmetry of the universe and/or increasing the energy density of active neutrinos can eliminate these contradictions and reconcile the possible existence of sterile neutrinos with Primordial Nucleosynthesis, the CMB anisotropy, and also reduce the H0-tension. In this brief review, we discuss the influence of the physical properties of active and sterile neutrinos on the evolution of the universe from the Big Bang to the present day.

Published: April 2024

Probiotics are safe, inexpensive, and effective feed additives, and Clostridium butyricum (CB) has been reported to regulate bone health in addition to having conventional probiotic effects. The bone health of laying hens is closely related to their production performance. Here, we investigated the effects of CB supplementation on the bone health and performance of laying hens. We added CB to the feed of green-shell laying hens, Luhua laying hens, and Hy-line Brown laying hens and examined changes in body weight, feed intake, egg production performance, and egg quality to determine the impact of CB on production performance. The impact of CB on the bones of laying hens was determined by analyzing the bone index, bone bending strength, bone calcium and phosphorus content, and bone mineral density. The study found that CB had little effect on the body weight and feed intake of laying hens. Feed additions of 108 and 109 CFU/kg CB can significantly increase the tibia index and bone mineral density of four-week-old green-shell laying hens. Feed additions of 107 and 108 CFU/kg CB can significantly increase the average egg weight, eggshell weight, and tibia index of 26-week-old Luhua laying hens, but 107 CFU/kg CB will reduce the egg production rate. Adding 108 CFU/kg CB to feed can significantly increase the average egg weight, eggshell weight, and tibia bending strength of 40-week-old Hy-line Brown laying hens. In summary, adding 108 CFU/kg CB is beneficial to the bone and production health of laying hens.

Published: April 2024

Used water treatment is one of the most important aspects of environmental protection regarding industrial processes. Particulate matter dispersions affect water parameters; for example, increased pH values such as 10.21 are found for used floor tile water, and values of 10.84 are found for used wall tile water. However, pH decreases to about 9.42 after the sediment filtration process. This influences water turbidity, which is higher for used wall tile water due to its finer suspensions, and it is considerably decreased after the filtration process. Thus, the main aim of the present research is to investigate particulate matter dispersion into the water flows that are involved in ceramic tile technological processes before and after treatment at used water treatment facilities. X-ray diffraction (XRD) coupled with mineralogical optical microscopy (MOM) reveals that waters from wall tiles and floor tiles have similar mineral dispersions, containing mineral particles of quartz (5–50 μm), kaolinite (1–30 μm), and mullite (5–125 μm). Glass particles (having a dark appearance at MOM investigation) were also found in both samples in a size range of 20–55 μm. High-resolution SEM imaging coupled with the EDS elemental analysis confirms the XRD and MOM observations. Water samples collected after treatment at the treatment facility reveal a significant reduction in the particulate matter MOM, evidencing only small traces of quartz, kaolinite, and mullite in a size range of 1–15 μm, with most of the particles being attached to the filters, as confirmed by XRD. Atomic force microscopy (AFM) effectuated on this sample reveals the presence of kaolinite nanoparticles with a tabular–lamellar aspect and sizes ranging from 40 to 90 nm. The obtained results prove the efficacy of the filtering system regarding targeted particulate matters, ensuring water recirculation into the technological processes. The sludge resulting from the filtration process presents with a dense grainy structure of sediment particles containing quartz, mullite, and kaolinite, along with traces of iron hydroxide crystallized as goethite. Therefore, it cannot be reused in the technological flux, as the iron causes glaze staining; but the observed microstructure, along with the mineralogical composition, indicates that it could be used for other applications, such as ecological bricks or plasters, which will be further investigated.

A Leishmaniose Visceral (LV) é uma zoonose considerada um problema de saúde pública mundial, afetando mais de 3500 pessoas anualmente em todo o Brasil, segundo o Ministério da Saúde. A LV é transmitida por mosquitos infectados pelo protozoário Leishmania, predominando em regiões tropicais e subtropicais com crescente taxa de letalidade. Este trabalho tem como objetivo estabelecer uma revisão dos aspectos clínico-epidemiológicos da LV no Brasil, ressaltando mudanças na distribuição geográfica da doença, sua incidência na região do sudoeste baiano, bem como revisar as atualizações na terapêutica da doença. O trabalho trata-se de uma pesquisa bibliográfica de caráter descritivo, com as buscas feitas nas plataformas digitais: Scielo, pubmed e bibliotecas acadêmicas, assim como livros de referência na área de pesquisa. A LV tem apresentado mudanças importantes no padrão de transmissão e epidemiologia, com aumento da incidência em centros urbanos. A coinfecção LV/HIV é um problema relevante, com aumento dos casos na região Nordeste do Brasil. O tratamento da LV inclui drogas como Antimoniato N-metil glucamina, Anfotericina B e Miltefosina, com diferentes perfis de eficácia e efeitos colaterais. Embora seja uma doença que acrescentou decréscimo na incidência, ainda tem altas taxas de letalidade, tornando importante o diagnóstico precoce e tratamento eficaz com controle de complicações.

Oral health serves as a crucial indicator of individuals' overall well-being and quality of life, making it a pertinent concern regularly addressed by healthcare professionals. Utilizing imaging exams is imperative for detecting and identifying oral diseases and conditions, and the application of Artificial Intelligence (AI) has garnered attention for its potential in this realm. We conducted a systematic literature review focusing on the utilization of Deep Learning techniques in dental radiographs for the detection, segmentation, and classification of teeth, caries, and restorations. Our review encompassed automated searches across prominent databases including the ACM Digital Library, IEEE Xplore Digital Library, PubMed, and Scopus, yielding 393 primary papers published between 2012 and 2023. Following stringent inclusion and exclusion criteria, we thoroughly examined 68 papers, assessing their consistency and adequacy of different aspects in terms of the databases used, techniques implemented, and outcomes reported. It was noted that 41.66% of the analyzed papers lacked clear information regarding approval of data usage from ethics committees. Additionally, despite the interdisciplinary nature of computational techniques in oral health, 38.23% of the surveyed studies were conducted by teams comprising solely professionals from one specific area. Moreover, 66.18% of the papers focused solely on panoramic radiographs, with commonly utilized metrics including accuracy, recall, and precision. Notably, the U-Net and Mask R-CNN networks emerged as the most frequently applied methodologies. Despite the proliferation of investigations in this field, several challenges persist, including the limited availability of public datasets, inadequate detailing of developed methodologies, and a lack of systematization in result presentation. These challenges hinder a fair comparison between studies, presenting a significant obstacle to be addressed for further progress in the field.

Estudos realizados com adultos portadores de Transtorno de Déficit de Atenção e Hiperatividade (TDAH) apontam que as manifestações de déficit de atenção em adultos são mais evidentes no ambiente de trabalho, com consequências como insucesso ocupacional e insatisfação laboral. As habilidades sociais estão diretamente interligadas com a eficácia individual e grupal de trabalhadores no ambiente de trabalho. Estudos em habilidades sociais de profissionais otimizam os resultados organizacionais e ajudam organizações e profissionais a se destacarem. A partir desta perspectiva, o presente projeto apresenta a criação de um instrumento de avaliação de TDAH adulto, a fim de avaliar prejuízos nas habilidades sociais de colaboradores que impactam a rotina de trabalho. Para tanto, foram avaliados critérios diagnósticos de TDAH adulto estabelecidos pelo DSM-5 (2013) e DSM-5-TR – uma vez que não há mudanças significativas na classificação deste transtorno na versão mais atualizada; artigos a respeito das especificidades do transtorno na fase adulta; conceitos de habilidades sociais no trabalho e seus prejuízos em pessoas com TDAH; e escalas preexistentes para avaliação de TDAH. Além disso, foi realizada uma revisão bibliográfica a fim de delimitar características de avaliações psicológicas para criação e validação de instrumentos. Na discussão fica evidente que desenvolver um bom repertório em habilidades sociais é considerado um fator de proteção na prevenção de psicopatologias como depressão e ansiedade no ambiente de trabalho. Além disso, está associado ainda com resultados profissionais mais satisfatórios e à vontade do funcionário em permanecer no mesmo emprego. O instrumento desenvolvido, com 40 itens em formato de escala Likert, possibilita estabelecer áreas de dificuldades relacionadas às habilidades sociais de adultos com TDAH no ambiente laboral e contribui para a melhoria da qualidade de vida do trabalho. Pode funcionar como instrumento inicial de apoio em avaliações psicológicas e indicar prejuízos a serem aprofundados.

O Diabetes Mellitus do tipo 2 (DM2) se manifesta através do desenvolvimento de hiperglicemia em jejum e pós-prandial, que é um dos principais contribuintes para muitas complicações e comorbidades potencialmente fatais. A incidência do DM2 aumentou significativamente na população brasileira nos últimos anos e atualmente é uma das doenças crônicas mais prevalentes no país. Estudar a abordagem multidisciplinar do Diabetes Mellitus Tipo 2, a fim de elucidar o tema e demonstrar o benefício de um correto tratamento, contribuindo para o melhor prognóstico do doente. Revisão integrativa da literatura realizada nas bases de dados do Portal Regional da BVS, SciELO e PubMed. A abordagem da terapia multidisciplinar do DM2 deve ser focada no manejo integrado com múltiplos objetivos de tratamento, incluindo controle de glicose, pressão arterial, manejo do estilo de vida, consultas regulares e triagem para prevenção de morbidades do DM2. De acordo com os estudos, esta abordagem levou a poupanças de custos e a uma redução da carga de doenças para os sistemas de saúde relacionadas com menos hospitalizações e eventos vasculares. Concluiu-se que a abordagem multidisciplinar se tornou uma importante ferramenta para o controle do Diabetes Mellitus tipo 2, assim como de outras comorbidades associadas a essa patologia. Ademais, o manejo integrado em diferentes esferas auxilia no acompanhamento longitudinal do paciente, com o intuito de evitar complicações a longo prazo danosas a saúde dos indivíduos.
