Cephalometric analysis is critically important and common procedure prior to orthodontic treatment and orthognathic surgery. Recently, deep learning approaches have been proposed for automatic 3D cephalometric analysis based on landmarking from CBCT scans. However, these approaches have relied on uniform datasets from a single center or imaging device but without considering patient ethnicity. In addition, previous works have considered a limited number of clinically relevant cephalometric landmarks and the approaches were computationally infeasible, both impairing integration into clinical workflow. Here our aim is to analyze the clinical applicability of a light-weight deep learning neural network for fast localization of 46 clinically significant cephalometric landmarks with multi-center, multi-ethnic, and multi-device data consisting of 309 CBCT scans from Finnish and Thai patients. The localization performance of our approach resulted in the mean distance of 1.99 ± 1.55 mm for the Finnish cohort and 1.96 ± 1.25 mm for the Thai cohort. This performance turned out to be clinically significant i.e., ≤ 2 mm with 61.7% and 64.3% of the landmarks with Finnish and Thai cohorts, respectively. Furthermore, the estimated landmarks were used to measure cephalometric characteristics successfully i.e., with ≤ 2 mm or ≤ 2° error, on 85.9% of the Finnish and 74.4% of the Thai cases. Between the two patient cohorts, 33 of the landmarks and all cephalometric characteristics had no statistically significant difference (p < 0.05) measured by the Mann-Whitney U test with Benjamini–Hochberg correction. Moreover, our method is found to be computationally light, i.e., providing the predictions with the mean duration of 0.77 s and 2.27 s with single machine GPU and CPU computing, respectively. Our findings advocate for the inclusion of this method into clinical settings based on its technical feasibility and robustness across varied clinical datasets.
Hybrid operating rooms and the risk of postoperative hypothermia in pregnant women with placenta previa: A retrospective cohort study
Authors: Lee Sou Hyun , Lee You Hyun
Published: June 2024

Background

Births at advanced maternal ages (≥ 35 years) are increasing. This has been associated with a higher incidence of placenta previa, which increases bleeding risk. Hybrid operating rooms, designed to accommodate interventions and cesarean sections, are becoming more prominent because of their dual capabilities and benefits. However, they have been associated with increased postoperative hypothermia in pediatric settings; moreover, this has not been studied in pregnant women with placenta previa.

Methods

This retrospective cohort study included pregnant women diagnosed with placenta previa who underwent elective cesarean section under general anesthesia between May 2019 and 2023. The patients were categorized according to the operating room type. The primary outcome was to determine whether the hybrid operating room is a risk factor for immediate postoperative hypothermia, defined as a tympanic membrane temperature below 36.0°C. The secondary outcomes were the effects of immediate postoperative hypothermia on the durations of postanesthetic care unit and postoperative hospital stays and incidence of complications.

Results

Immediate postoperative hypothermia (tympanic membrane temperature < 36.0°C) was more prevalent in the hybrid than in the standard operating room group (20% vs. 36.6%, p = 0.033), with a relative risk of 2.86 (95% confidence interval 1.24–6.64, p < 0.001). Patients undergoing surgery in the hybrid operating room who experienced immediate postoperative hypothermia stayed longer in the postanesthetic care unit (26 min vs. 40 min, p < 0.001) and in the hospital after surgery (4 days; range 3–5 vs. 4 days; range 4–11, p = 0.021). However, the complication rates of both groups were not significantly different (11.3% vs 7.3%, p = 0.743).

Conclusion

Hybrid operating rooms may increase the risk of postoperative hypothermia. Postoperative hypothermia is associated with prolonged postanesthetic care unit and hospital stays. Preventing hypothermia in patients in hybrid operating rooms is of utmost importance.
Association of Medicaid coverage with emergency department utilization after self-harm in Korea: A nationwide registry-based study
Authors: Han Ga In , Jeong Sikyoung , Kim Insoo , Yuh Min Ah , Woo Seon Hee , Hong Sungyoup
Published: June 2024

Background

Self-harm presents an important public health challenge. It imposes a notable burden on the utilization of emergency department (ED) services and medical expenses from patients and family. The Medicaid system is vital in providing financial support for individuals who struggle with medical expenses. This study explored the association of Medicaid coverage with ED visits following incidents of self-harm, utilizing nationwide ED surveillance data in Korea.

Methods

Data of all patients older than 14 years who presented to EDs following incidents of self-harm irrespective of intention to end their life, including cases of self-poisoning, were gathered from the National ED Information System (NEDIS). The annual self-harm visit rate (SHVR) per 100,000 people was calculated for each province and a generalized linear model analysis was conducted, with SHVR as a dependent variable and factors related to Medicaid coverage as independent variables.

Results

A 1% increase in Medicaid enrollment rate was linked to a significant decrease of 14% in SHVR. Each additional 1,000 Korean Won of Medicaid spending per enrollee was correlated with a 1% reduction in SHVR. However, an increase in Medicaid visits per enrollee and an extension of Medicaid coverage days were associated with an increase in SHVR. SHVR exhibited a stronger associated with parameters of Medicaid coverage in adolescents and young adults than in older adult population.

Conclusion

Expansion of Medicaid coverage coupled with careful monitoring of shifts in Medicaid utilization patterns can mitigate ED overloading by reducing visits related to self-harm.

Authors: Elhence Hirsh , Dodge Jennifer L. , Kahn Jeffrey A. , Lee Brian P.
Published: June 2024

INTRODUCTION:

The National Institute on Minority Health and Health Disparities has noted that transgender individuals experience unique health disparities. We sought to describe the landscape of transgender patients with cirrhosis.

METHODS:

We identified all transgender and cisgender adults in Optum's deidentified Clinformatics Data Mart Database between 2007 and 2022 using validated billing codes and calculating age-standardized prevalence of cirrhosis among cisgender vs transgender adults. Among those with incident cirrhosis diagnoses, we calculated age-standardized incidence densities of liver-related outcomes (decompensation, transplantation, hepatocellular carcinoma) and all-cause mortality. We examined 5-year survival using inverse probability treatment weighting to balance transgender and cisgender populations on demographic and clinical characteristics.

RESULTS:

Among 64,615,316 adults, 42,471 (0.07%) were transgender. Among 329,251 adults with cirrhosis, 293 (0.09%) were transgender. Trans- (vs cis-) genders had higher prevalence of cirrhosis (1,285 [95% confidence interval (CI) 1,136–1,449] per 100,000 vs 561 [559–563] per 100,000). Among adults with cirrhosis, trans- (vs cis-) genders had higher proportions of anxiety (70.7% [56.9–86.9] vs 43.2% [42.7–43.8]), depression (66.4% [53.3–81.7] vs 38.4% [37.9–38.9]), HIV/AIDS (8.5% [3.9–16.1] vs 1.6% [1.5–1.7]), and alcohol (57.5% [46.0–71.1] vs 51.0% [50.5–51.6]) and viral (30.5% [22.8–39.8] vs 24.2% [23.9–24.5]) etiologies, although etiologies had overlapping CIs. Trans- (vs cis-) genders had similar incidence densities of death (12.0 [95% CI 8.8–15.3] vs 14.0 [13.9–14.2] per 100 person-years), decompensation (15.7 [10.9–20.5] vs 14.1 [14.0–14.3]), and liver transplantation (0.3 [0.0–0.8] vs 0.3 [0.3–0.4]). In inverse probability treatment weighting survival analysis, transgender and cisgender individuals had similar 5-year survival probabilities (63.4% [56.6–71.1] vs 59.1% [58.7–59.4]).

DISCUSSION:

Trans- (vs cis-) gender adults have double the prevalence of cirrhosis, and the majority have a diagnosis of anxiety and/or depression. These results are informative for researchers, policymakers, and clinicians to advance equitable care for transgender individuals.

Published: June 2024

Motivation is still taken into consideration when ones apply to a minor in a study program with limited seats. The present study explores students’ motivational dimensions for choosing Japanese language stream which has limited quota in an Indonesian vocational college. Based on responses from 43 first-year students choosing Japanese stream, it was found that ‘personal goals’ dominated the list of motivational dimensions. In contrast, no student expressed ‘external pressures/incentives’ as their motivation. Following screening process conducted by the study program, ‘personal goals’ maintained its position as the most frequently expressed motivation. Moreover, ‘academic interests’ appeared as the motivational dimension which did not change in number following screening process. These results demonstrate the attraction of the internship program in Japan promoted by the study program in recent years.

Authors: Hasibuan Sekar Fatinah , Alfarisy Fitri
Published: June 2024

Lifestyle is a set of behaviours that are meaningful to the individual and others at a particular time and place, including social relationships, consumption of goods, entertainment, and clothing. Minimalism is the act of reducing things to make room for the more important things in life. A minimalist lifestyle is influenced by a consumptive lifestyle by reducing the items owned. Japanese minimalism has a rich history and is linked to cultural and philosophical traditions. A minimalist lifestyle is characterised by anti-consumerist attitudes and behaviours. A minimalist lifestyle offers many wellbeing benefits, including happiness, life satisfaction, meaning, and better personal relationships. Practising a minimalist lifestyle can be manifested by problem-avoiding behaviours, being content with enough possessions, and thinking carefully before making new purchases. The benefits of living a minimalist lifestyle range from environmental sustainability to mental health. This research aims to understand how Fumio Sasaki represents Japanese culture through the theme of minimalism and identify the Japanese cultural values reflected in this book with a qualitative method by thoroughly describing the data obtained during the research process. This research uses a literature approach by referring to theories obtained from literature in the form of books and journals as the main source and the literature.

Published: June 2024

Ecocide, an illegal act that causes serious damage to the environment, has become one of the greatest threats to the planet. Ukraine,
which has recently been exposed to ecocide, strives to bring the perpetrators to justice by applying to international judicial bodies and
creating mechanisms for collecting evidence. Ecocide should be included in the list of crimes against humanity and properly regulated
at the international level, which will contribute to the preservation of the environment and human security. The purpose of this article is
to define the crime of ecocide under international humanitarian law, apply it to the conflict in Ukraine, and discuss possible international
mechanisms for bringing to justice those who have committed ecocide. This paper showcases Ukraine’s legal and factual basis for holding
Russia accountable for ecocide, which includes the destruction of natural resources, water and air pollution and actions that could result in
environmental catastrophes. This paper emphasizes the importance of filing lawsuits with international bodies, international cooperation,
public engagement, and resource mobilization for effective prosecution. Ukraine’s commitment to environmental protection through the
pursuit of ecocide accountability is of global significance for the preservation of the planet and well-being of future generations.
The History and Possibilities of Distributing Music in the 21st Century
Authors: Mański Szymon
Published: June 2024

The goal of the present article is to observe the evolution of streaming services, this being one of many prospects for the distribution of alternative music. It would be unrealistic to compare the first of them, which arose at the end of the 1990s, to today’s methods, which provide multiple ways and techniques to support the artists and simultaneously satisfy the hunger for new sounds in audiences. Discussing it from the scientific perspective of studies regarding the legality of musical distribution, in conjunction with the development of the underground music scene, the author – as a musician himself – attempts to introduce the functionality of sound-streaming media as an area for shaping the musical taste of individual listeners, an artistic activity firmly reliant on the cooperation of the artists and their audiences. The article is based on studies conducted by the author in 2021–2023.

Relative Rota–Baxter groups and skew left braces
Authors: Rathee Nishant , Singh Mahender
Published: June 2024

Relative Rota–Baxter groups are generalizations of Rota–Baxter groups and have been introduced recently in the context of Lie groups. In this paper, we explore connections of relative Rota–Baxter groups with skew left braces, which are well known to give bijective non-degenerate set-theoretical solutions of the Yang–Baxter equation. We prove that every relative Rota–Baxter group gives rise to a skew left brace, and conversely, every skew left brace arises from a relative Rota–Baxter group. It turns out that there is an isomorphism between the two categories under some mild restrictions. We propose an efficient GAP algorithm, which would enable the computation of relative Rota–Baxter operators on finite groups. In the end, we introduce the notion of isoclinism of relative Rota–Baxter groups and prove that an isoclinism of these objects induces an isoclinism of corresponding skew left braces.
Application of locally regularized extremal shift to the problem of realization of a prescribed motion
Authors: Osipov Yury S. , Maksimov Vyacheslav I.
Published: June 2024

A controlled system of differential equations under the action of an unknown disturbance is
considered. The problem discussed in the paper consists in constructing algorithms for forming a control that
provides the realization of a prescribed motion for any admissible disturbance. Namely these algorithms should
provide the closeness in the metric of the space of differentiable functions of a phase trajectory of a given
controlled system and some etalon trajectory of an analogous system functioning when any outer actions are absent.
As the space of admissible disturbances, we take the space of measurable square integrable (with respect to the
Euclidean norm) functions. The cases of inaccurate measurements of phase trajectories of both systems at all times
and at discrete times are under study. Two computer oriented algorithms for solving the problem are designed. The
algorithms are based on the (well-known in the theory of guaranteed control) method of extremal shift. In the
process, its local (at each time of control correction) regularization is performed by the method of smoothing
functional (the Tikhonov method). In addition, estimates for algorithm’s convergence rate are presented.

Authors: Rasu Karthick , Veerabathiran Anbumalar
Published: June 2024

This work presents the influence of betel nut fiber hybridization on the properties (mechanical, thermal, wear, and water absorption) of novel aloevera fiber-reinforced vinyl ester composites. In this research, we fabricated the composites by changing the wt.% of aloevera fiber and betel nut fiber through the hand layup method using the compression molding technique. From the results, it has been observed that increases in wt.% of betel nut fiber increased the mechanical properties, thermal properties, wear resistance, and water resistance of the composites. The composite with the designation S1 shows the lowest hardness, tensile, flexural, impact, and shear strengths of 49.58, 26.59 MPa, 52.53 MPa, 4.12 J, and 101.26 MPa, respectively. Meanwhile, the composite with the designation S5 shows the highest hardness, tensile, flexural, impact, and shear strengths of 71.29, 62.61 MPa, 78.24 MPa, 9.57 J, and 139.52 MPa, respectively. Further, higher wear resistance and water resistance were obtained by the S5 specimen. SEM analysis shows the good strength of betel nut fiber and enhances the tensile strength of the composites.
Modeling the strength parameters of agro waste-derived geopolymer concrete using advanced machine intelligence techniques
Authors: Al-Naghi Ahmed A. Alawi , Amin Muhammad Nasir , Khan Suleman Ayub , Qadir Muhammad Tahir
Published: June 2024

The mechanical strength of geopolymer concrete incorporating corncob ash and slag (SCA-GPC) was estimated by means of three distinct AI methods: a support vector machine (SVM), two ensemble methods called bagging regressor (BR), and random forest regressor (RFR). The developed models were validated using statistical tests, absolute error assessment, and the coefficient of determination (R
2). The importance of various modeling factors was determined by means of interaction diagrams. When estimating the flexural strength and compressive strength of SCA-GPC, R
2 values of over 0.85 were measured between the actual and predicted findings using both individual and ensemble AI models. Statistical testing and k-fold analysis for error evaluation revealed that the RFR model outperformed the SVM and BR models in terms of accuracy. As demonstrated by the interaction graphs, the mechanical characteristics of SCA-GPC were found to be extremely responsive to the mix proportions of ground granulated blast furnace slag, fine aggregate, and corncob ash. This was the case for all three components. This study demonstrated that highly precise estimations of mechanical properties for SCA-GPC can be made using ensemble AI techniques. Improvements in geopolymer concrete performance can be achieved by the implementation of such practices.
Hydrothermal syntheses, structures and properties of two zinc complexes based on an azobenzene carboxylate ligand

n
(2) (LH− = 2-hydroxy-5-((3-nitrophenyl)azo)-benzoate, phen = 1,10-phenanthroline) were synthesized by hydrothermal methods and characterized by elemental analysis and IR spectroscopy. Complexes 1 and 2 crystallize in mononuclear and polymeric structures, respectively, where ligands L
2− are coordinated to the zinc ions via their carboxylate and phenolate groups in η
2,μ
2,κ
2 and η
2,μ

1 mode, respectively. Introduction of the auxiliary chelating phen ligand results in the chelation of the zinc ions in 1 through both the phen ligand and the carboxylate group of the first LH− anion assisted further by the monodentate carboxylate group of the second LH− anion. In complex 2 the L
2− anions act as tridentate ligands utilizing their carboxylate and phenolate groups to coordinate to three zinc ions. The phenolate oxygen atom bridges two zinc ions resulting in the generation of a layer structure. Fluorescence measurements have indicated that complexes 1 and 2 exhibit similar luminescence emissions around 393 and 387 nm, respectively, which originate from intra-ligand π-π* transitions. The emission intensities were strengthened relative to the sodium complex NaLH owing to the enhancement of the rigidity of the aromatic system through the coordination interactions of the ligands with the more tightly bound zinc ions. Furthermore, the suspension of complex 2 can be used to selectively detect Fe3+ cations via the luminescence quenching process.
A New Training Load Quantification Method at Supramaximal Intensity and Its Application in Injuries Among Members of an International Volleyball Team

Published: June 2024

Bouzigues, T, Maurelli, O, Imbach, F, Prioux, J, and Candau, R. A new training load quantification method at supramaximal intensity and its application in injuries among members of an international volleyball team. J Strength Cond Res 38(8): 1453–1463, 2024—The quantification of training loads (TLs) is essential for optimizing jump performance and reducing the occurrence of injuries. This study aimed to (a) propose a new method for quantifying TLs in explosive exercises, (b) determine the nature of the relationship between TLs dynamics and injury occurrence, and (c) assess a TLcritical for training schedule purposes, above which the risk of injury occurrence becomes unacceptable. This study was conducted with 11 male volleyball players on a national team during a 5-month international competitive period. The proposed new method for quantifying TLs is based on a weighting factor applied to relative jumping intensities, determined by the number of sustainable jumps and their intensities measured by G-Vert accelerometer. The relationship between TLs dynamics and injury occurrence was assessed using a variable dose-response model. A high coefficient of determination was found between the maximum number of jumps possible and their intensities (r
2 = 0.94 ± 0.14, p < 0.001), indicating a strong physiological relationship between jumping intensities and the constraints imposed. The occurrence of injury was dependent on TLs dynamics for 2 players (r
2 = 0.26 ± 0.01; p < 0.001). The TLcritical corresponded to 11 jumps over 80% of maximum jump height during games and approximately 130 jumps at <80% of maximal jump height. The present study proposes a new approach for quantifying supramaximal exercises and provides tools for training schedules and the prevention of volleyball injuries.

Effect of Process Parameters on Immobilization of Recombinant Escherichia coli on Coconut Fiber
Authors: Che Man Rohaida , Abdul Mudalip Siti Kholijah , Abdul Manas Nor Hasmaliana , Sulaiman Siti Zubaidah
Published: June 2024

Escherichia coli (E. coli) is the earliest and most widely used host to produce recombinant proteins, one such example being cyclodextrin glucanotransferase (CGTase) which has found application in numerous industries such as food, environmental engineering and pharmaceutical. The recombinant protein in E. coli was applied to overcome the low output of CGTase from Bacillus species such as Bacillus lehensis and Bacillus licheniformis. However, cell lysis and plasmid instability have been some of the stumbling blocks during the production of recombinant protein in E. coli. Therefore, cell immobilization has been proposed as a way to increase CGTase production while maintaining high cell stability. The objective of this study is to immobilize recombinant E. coli on coconut fiber. The effect of the process parameters, namely pH level (5, 6, 7, 8, and 9), contact time (12, 15, 18, 21, 24, and 27 hours), and temperature (20, 25, 30, 35, and 40 °C), towards the immobilization of recombinant E. coli onto coconut fiber was studied.  The optimal pH resulted in the highest immobilization yield was pH 8 (58.90%).

Satisfaction is a crucial aspect of a marital relationship. The subjective nature of an individual's views and reactions to their marriage is a well-documented phenomenon. The potential for various risks to arise if individuals are dissatisfied with their marriage is considerable. One such risk is the potential for separation. One aspect of sexuality that can influence marital satisfaction is sexual motivation. One of the principal determinants of marital satisfaction is the individual's motive for engaging in sexual relations. The objective of this research is to ascertain the relationship between sexual motivation and marital satisfaction in young married adult men. This research employs quantitative methods. The subjects of this research were 604 participants. The sampling technique employed a purposive sampling approach, with the subjects comprising married young adult males, aged between 20 and 40 years. Marital satisfaction was gauged utilizing the Relationship Assessment Scale (RAS) instrument, while sexual motivation was quantified using the Multidimensional Sexual-Self Concept Questionnaire (MSCCQ) instrument. The results of Spearman's rho analysis indicate that the p value is .508, which is greater than .05. This indicates that there is no correlation between sexual motivation and marital satisfaction in young adult men. Further research is required to ascertain whether there are intervening variables that can explain the correlation between the two research variables

This study aims to determine the effect of the addition of cellulose nanocrystals (CNC) with different concentrations (0,2,4,6,8,10%) isolated from water hyacinth on tensile strength, elongation, and biodegradability of corn starch bioplastics. CNC isolation was conducted, including alkalization, bleaching, acid hydrolysis, and sonication. After the isolation process, CNC was characterized based on functional group, crystallinity, and morphology surface. Then, the production of starch bioplastic using solution casting was carried out with the addition of CNC. The results showed chemical treatments affected the functional group, increasing the crystallinity index, and removing the fibril structure in water hyacinth fibers. Likewise, the addition of CNC to starch bioplastic fluctuated the tensile strength and elongation. In the biodegradability test, the physical appearance of the bioplastic completely changed. Then, the optimum mass reduction occurred in the 6% CNC on the 10th day.

Used cooking oil is a waste that is produced every day and is increasing. Used cooking oil cannot be consumed again because it contains dangerous substances that will cause disease, but it also cannot be thrown away since it will pollute the environment. Therefore, it is necessary to process used cooking oil, one of which is purification using the adsorption method. The adsorption method for used cooking oil can be derived from green dregs because greens contain antioxidants which can reduce the content of dangerous substances in used cooking oil. In this study, we used variations in adsorbent mass (10 gr, 20 gr, 30 gr, 40 gr, and 50 gr) and stirring time (25 minutes, 45 minutes, 65 minutes, 86 minutes, and 105 minutes) to obtain the highest purification results. was the best and it was found that the adsorbent mass of 50 grams of green dregs and a stirring time of 105 minutes had the best results in being able to reduce the peroxide value, air content and free fatty acids. Next, the purified used cooking oil will be processed into floor cleaning liquid soap with the addition of 2 ml, 4 ml, 6 ml, 8 ml and 10 ml of pineapple peel extract. The results of the floor cleaning soap showed that the best results were 2 ml based on the alkaline number, pH and anti-bacterial test.

There has been an acceleration in competence-based management in recent years, which has, in turn, influenced entrepreneurial success by strengthening entrepreneurial competencies. This study aims to analyse and predict the future of the research on entrepreneurial competencies using bibliometric methods. For this purpose, VOSviewer software was used for co-word analysis. Bibliometric methods such as citation analysis and co-author analysis were used to analyse the studies related to entrepreneurial competencies. It was found that most publications were published in 2019 based on a search in the Web of Science database between 1995 and 2023. The analysis of 1403 publications revealed that 460 proceeding papers, 10 early access and 210 book chapters were involved in the search. After reducing the set to include articles, 914 papers were evaluated. Results show that the authors most cited over the years are Lans Thomas, Al Mamun Abdullah, Mulder Martin, and Obschonka. Furthermore, it was found that Spain had the highest number of published works, followed by China and the USA respectively. Study findings also revealed that entrepreneurial competencies are more related to core, emotional, and network competencies and sustainable development, creativity, innovation, social capital, and higher education.
Interplay between caveolin-1 and mineralocorticoid receptor in cardiometabolic disease
Authors: Czarzasta Katarzyna , Pojoga Luminita H
Published: June 2024

Over the past decades, research has clearly established the important role of the mineralocorticoid receptor (MR) in both renal and extra-renal tissues. Recently, caveolin-1 (Cav-1) has emerged as a mediator of MR signaling in several tissues, with implications on cardiovascular and metabolic dysfunction. The main structural component of caveolae (plasma membrane invaginations with diverse functions), Cav-1 is a modulator of cardiovascular function, cellular glucose, and lipid homeostasis, via its effects on signal transduction pathways that mediate inflammatory responses and oxidative stress. In this review, we present evidence indicating an overlap between the roles of the MR and Cav-1 in cardiometabolic disease and the relevant signaling pathways involved. Furthermore, we discuss the potential use of Cav-1 as a biomarker and/or target for MR-mediated dysfunction.

Published: June 2024

The rapidly rising incidence of obesity, coupled with type 2 diabetes mellitus (T2DM), is a growing concern. Glucagon-like peptide 1 (GLP-1), an endogenous peptide secreted by enteroendocrine L-cells, demonstrates exceptional pharmacological potential for the treatment of T2DM and obesity, primarily through its pivotal roles in regulating glucose homeostasis, stimulating glucose-dependent insulin secretion, and promoting satiety. Considering its proven efficacy in glucoregulation and weight loss, GLP-1 receptor agonists (GLP-1RAs) have emerged as a revolutionary breakthrough in the arena of diabetes management and weight control. Additional gastrointestinal hormones, such as glucose-dependent insulinotropic peptide (GIP) and glucagon, exhibit structural similarities to GLP-1 and work synergistically to lower blood glucose levels or aid in weight loss. Today, various classes of gut hormone receptor multiple agonists are steadily progressing through development and clinical trials, including dual GLP-1/glucagon receptor agonists (first discovered in 2009), dual GLP-1/GIP receptor agonists (first described in 2013), and triple GLP-1/GIP/glucagon receptor agonists (initially designed in 2015). The GLP-1/GIP receptor co-agonist, tirzepatide, was approved by the U.S. Food and Drug Administration (FDA) for the treatment of T2DM, outperforming basal insulin or selective GLP-1RAs by providing superior HbA1c reductions. Remarkably, tirzepatide also facilitated unprecedented weight loss of up to 22.5% in non-diabetic individuals living with obesity. This result is comparable to those achieved with certain types of bariatric surgery. Therefore, the advent of gut hormone multi-agonists signifies the dawn of an exciting new era in peptide-based therapy for obesity and T2DM. This review offers a comprehensive summary of the various types of gut hormone multiple agonists, including their discovery, development, action of mechanisms, and clinical effectiveness. We further delve into potential hurdles, limitations, and prospective advancements in the field.

Authors: Ambrulevičiūtė Aelita
Published: June 2024

The article examines the origin of the name “Pohulianka”, the western suburb of Vilnius, and establishes the chronology of the usage of this name from the first mentions in city plans to its disappearance from the topography of the city due to the Lithuanianization of urbanonyms in 1939–1940. Based on cartographic and written sources, the dynamics of the suburb boundaries are analyzed in the context of the changing urban name in 1790–1940.

Several studies have recently been carried out on the avifauna of Cameroon and have made it possible to update the data for certain regions; however, no recent study has been carried out on the upper valley of the Nyong River, which is a wetland, and therefore the data remains quite old. We carried out a study on the avifauna of this valley and birds were sampled over a period of one year using the mist-netting method. The collected data were analyzed using PAST bio statistical software for the diversity and distribution of the avifauna. A total of 268 individuals belonging to 69 bird species were captured, with a high proportion of passerines (73%) compared with non-passerines. The high diversity of the avifauna is supported by estimated values of diversity indexes which show an absence of supremacy of one species (H’=3.64) and an equal distribution of individuals in their environment (J’=0.86). With the value of the Simpson diversity index of 0.96, our result confirms high diversity within the upper valley of the Nyong River avifauna but it also reveals the abundance of this avifauna. In addition, the Kruskal-Wallis test value of 0.04 showed a significant difference in the distribution of relative abundances of taxa at the areas investigated and that different could be justified by a difference in the physiognomy of their vegetation. This study confirms that the composition as well as the structure of the upper valley of the Nyong River as observed in the field play a main role in the diversity of bird species due to the presence of feeding, resting and nesting areas. Based on our distribution and diversity analysis, the pattern of variation in distribution of birds in this wetland appears to lean on environmental factors and particularly the vegetation, which played the main role with a mixture of poor and good dispersers, migratory and vagrant due to presence of lush vegetation all year round.
