Authors: Alvarez Luis Sanandrés , Altamirano Danilo Vallejo , Salgado Myriam Ruiz
Published: October 2022

Currently, the theoretical basis of eco-efficiency in responsible and social development has promoted a philosophy of sustainable and environmental thinking, which is to provide solutions to the imbalance in the company–environment relationship. Thus, this scientific article is presented with the purpose of deepening the importance of eco-efficiency in responsible and social development and strengthening environmental performance. A quantitative–qualitative approach was used. The phenomenological interpretation to respond to environmental problems also describes the theoretical basis in a substantive way. In this sense, the optimization of resources is sought, with the vision of innovation and the commitment of each organization to be responsible for the high levels of pollution. Therefore, it is concluded that business awareness should be promoted, with approaches to mitigate environmental pollution. Thus, it is necessary to have government policies that motivate businessmen to change their relationship with the environment, based on transition and sustainable development for the integral development of the country. It is also necessary to articulate with the educational institutions at all levels to form beings sensitive to the interest and care for the environment.
Keywords: eco-efficiency, social responsibility, environmental performance, sustainability.
Resumen
En la actualidad, las bases teóricas de la ecoeficiencia en el desarrollo responsable y social, ha fomentado una filosofía del pensamiento sostenible y ambiental, que consiste en dar soluciones al desequilibrio en la relación empresa – ambiente, para tal efecto se presenta el artículo científico, con el propósito de profundizar la importancia de ecoeficiencia en el desarrollo responsable y social y fortalecer el performance ambiental, para lo cual se construye desde el enfoque cuantitativo – cualitativo; la interpretación fenomenológica para responder los problemas ambientales; además se describe las bases teóricas de una manera sustantiva. En este sentido se busca la optimización de recursos, con la visión de innovación y el compromiso de cada organización de ser responsable de los altos niveles de contaminación. Por tanto, se concluye que se debe fomentar la conciencia empresarial, con planteamientos para mitigar la contaminación ambiental. Así pues, es necesario que existan políticas gubernamentales que motiven a los empresarios al cambio en la relación con el medio ambiente, con base en la transición y el desarrollo sostenible para el desarrollo integral del país.

Published: October 2022

Background: The objective of this study was to evaluate treatment outcomes and assess predictors of clinical pregnancy in obstructive azoospermia cases treated with testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) in Ghana.
Methods: This study was a retrospective study conducted on 67 men seeking treatment for obstructive azoospermia at two study sites in Ghana from January 2018 to December 2019. First, archived data were reviewed and treatment outcomes of cases of obstructive azoospermia from the hospital records were evaluated. Infertile men who met the inclusion criteria were recruited. Descriptive data were expressed in the form of frequencies and percentages. The dependent and independent variables were analyzed using multiple logistic regression and reported as odds ratios (ORs). The confidence interval (CI) was set at 95% and a p-value <0.05 was considered significant.
Results: The mean age of male participants was 42.43±9.11 years (mean±SD) while the mean age of their partners was 32.89±5.73 years (mean±SD). The average duration of infertility before intervention was 5.01±3.60 years (mean±SD). Successful pregnancy was observed in 52.2% (35/67) of the participants. After adjusting for confounders, the rate of a successful clinical pregnancy was 0.07 lower for every additional year increase in the male’s age [AOR=0.93 (95%CI=0.87 - 0.99), p=0.02].  
Conclusion: Overall the rate of clinical pregnancy following TESE/ICSI from our study was 52.2%. A man’s age was a strong predictor of successful clinical pregnancy among couples treated with TESE-ICSI for obstructive azoospermia in Ghana.

Authors: Pourhoseini Seyed Azam , Babazadeh Raheleh , Mazlom Seyed Reza
Published: October 2022

Background: PCOS is a common endocrine disorder of reproductive age with high morbidity that its prevalence ranging from 5.6% to 26%. The aim of this study was to evaluate the prevalence of PCOS in Iranian adolescent girls aged 14-19 years based on adults and adolescents’ criteria.
Methods: This cross-sectional study was carried out with 650 high school adolescent girls in Mashhad city, north-east of Iran. PCOS was defined as the presence of three or two of the three features including oligo/amenorrhea, clinical or biochemical hyperandrogenism, and polycystic ovaries. Descriptive statistics, chi-square, and t-test were used to analyze the data through SPSS vs 22 (SPSS Inc., USA) and the significance level was set at p≤0.05.
Results: The mean age of adolescent girls was 16.73±3.4 years. The prevalence of PCOS using Rotterdam, National Institutes of Health (NIH), Androgen Excess– PCOS Society (AES), European Society of Human Reproduction and Embryology (ESHRE)/American Society for Reproductive Medicine (ASRM) (2012), and Endocrine Society Clinical Practice (2013) criteria was 4.2%, 3.6%, 3.6%, 0.7%, and 3.6%, respectively.
Conclusion: The rate for prevalence of PCOS calculated based on Rotterdam, NIH, AES, and Endocrine Society (2013) criteria was higher in comparison to ESHRE/ ASRM (2012) criteria. According to the results of our study, in order to prevent overestimation of this syndrome’s prevalence in the adolescents due to its overlap with signs of pubertal development, all above-mentioned three criteria should be considered together, which is in line with the recommendations proposed by Carmina et al. and ESHRE/ASRM working group.
On the Reliability of the Functioning of the Deploying Landing Module Mechanisms
Authors: Pokhabov Yu.P. , Blinov D.S. , Kolobov A.Yu.
Published: October 2022

The development of mechanisms for deploying, fixing nodes and systems of interplanetary automatic spacecraft landing modules is the most difficult engineering task, errors in its solution lead to critical or fatal failures. The fact that interplanetary missions are rare and the implementation of each of them is very expensive leads to the need for practically trouble-free operation of deploying mechanisms, which in turn requires improving the efficiency of design techniques and computational and experimental reliability assurance in the face of limited statistical data and incomplete knowledge of the conditions and effects of planets on interplanetary spacecraft. In contrast to foreign experience, in domestic practice insufficient attention is payed to the methodology for designing highly reliable opening and fixation mechanisms. The article considers approaches to the computational and experimental reliability assurance of the functioning the mechanisms for deploying landing modules. The factors having a decisive effect on the reliability of the deploying and fixation mechanisms are analyzed. It is shown that the reliability of the functioning the deploying and fixation mechanisms largely determines the reserves of driving moments (forces) of the deploying drives, taking into account design and technological factors, and for the landing module mechanisms, they should be calculated based on the conditions and effects of the destination planets (climatic, atmospheric and gravitational)
Technological Aspects of Improving the Power Gyroscope Performance Characteristics of Space Vehicles for Remote Earth Sensing Systems
Authors: Khrutskaya M.V.
Published: October 2022

The article considers the problems of controlling the preliminary axial load on the ball-bearing support of a power gyroscope rotor by the frequency method. The study of the effect of the power gyroscope rotor rotation speed on the natural oscillation frequency under varying environmental conditions was performed on a special installation that combines a thermal, vacuum chambers and vibration installation using statistical methods for identifying and optimizing complex systems. The relationship between the natural frequency of the rotor forced oscillations and the speed of rotation, ambient temperature and pressure is identified in the form of a mathematical model, with the effect of each parameter under study being of nonlinear character. It is found that the effect of the rotation speed on the natural frequency of power gyroscope rotor oscillations changes significantly at different values of ambient temperature and pressure, and the value of the natural frequency is maximum at the static position of the rotor. The results of the study allow performing natural frequency technological control at different stages of instrument assembling under controlled conditions and can be used in the development of methods for controlling the frequency characteristics of inertial actuators of orientation and stabilization systems

Hydrolysis of protein-polysaccharide components of plant materials under basic environmental conditions is the main mechanism of biochemical degradation of biomass in nature. Most modern synthetic polymeric materials do not have the ability to rapidly degrade in the environment after the end of their useful life. The aim of the work was to compare the kinetics of hydrolysis of protein-polysaccharide substances of plant origin and artificially created synthetic polymeric materials with biomarker units. The article studies the kinetics of hydrolysis of the basic constituents of natural materials on the example of model systems — vegetable protein of soy origin and vegetable carbohydrate — starch in comparison with the possible enzymatic biodegradation of a synthetic copolymer used for surface treatment of wood products — a copolymer of glycerol and phthalic anhydride. A methodology for the possible modification of the synthesis of such copolymers by introducing lactic acid fluctuation units into their structure, which increase the bioactivity of the polymer material, is described. The effect of lactic acid units in the composition of synthetic tercopolymer on the rate of its biodegradation has been revealed. The main kinetic constants of the decay rates and activation energies of the enzymatic hydrolysis of the studied objects were determined under conditions simulating their possible biodegradation in the environment. The values of the constants of the maximum rates of pancreatic biodegradation Vmax.102, ranged from 0,24 mg/ml·min–1 for the synthesized tercopolymer of glycerol, phthalic anhydride and lactic acid compared with similar values at the level of 1,43...2,29 mg /ml·min–1 for protein-polysaccharide substrates. It is shown that substances of a protein nature have the highest rate of biodegradation, and a synthetic copolymer of glycerol and phthalic anhydride in the form of glyphthalic resin has a significant resistance to biodegradation. Modification of such a copolymer by introducing lactic acid units into its structure makes it possible to increase its biodegradability. The expediency of modifying the eco-properties of synthetic polymers by introducing lactic acid units into their structure, which increase the biodegradability, has been confirmed.

A study was carried out by comparing the spatial data of the project for the organization and management in the Stavropol forestry enterprise. The total area of the Stavropol urban forestry from 1997 to 2021 increased by 564,7 hectares due to the addition of a steppe landscape territory. It was established that 429,75 hectares of forested areas were excluded from forestry. Based on the information from the Unified State Register of Real Estate, the areas that were excluded from the forestry are currently used for residential development. Satellite images show the boundaries of the territories of the stows in 1997 and 2021, marked with different colors of the territory excluded from the total area of forest areas, as well as added areas. The comparative analysis of data for 1997, 2013 and 2021 allows us to identify all the changes in the qualitative and quantitative aspects. In accordance with the results of the study, during the study period, there is a positive trend in the increase in the area of the Stavropol urban forestry. However, it has been established that, based on the results of a detailed analysis of changes in the area of natural boundaries and regional reserves, the area of forest lands that are part of the forestry has decreased. The analysis of the factors that had a negative impact on the forest fund was carried out.

Published: October 2022

Doğurganlığın küresel çapta düşmekte olduğu günümüz demografik yapılarında, makro yapısal süreçlerdeki değişimlerin neden olduğu etkenlerin yanı sıra düşünsel değişimler de düşen doğurganlığı açıklamaktadır. Bu düşünsel değişimler; antinatalizm ve çocuksuzluk akımlarının popülaritesinin artmasında da kendini göstermektedir. İki akımın ortak noktası olan çocuk istememe fikri, makro ölçekte doğurganlık hızının nüfusun yenilenme seviyesinin altına düşmesine neden olabilmektedir. Bu düşünce akımlarının ifadesini bulduğu mekânlar arasında sosyal medya platformları yer almaktadır. Çalışmada, sosyal medya platformlarından Reddit’te 2020-2021 yıllarında kendine yer bulan 217 adet “antinatalizm” ve 817 adet “çocuksuz” etiketli paylaşım, kategori ve ilişki analizine tabi tutulmuştur. Bu yolla akımların içinde üretilen temaları ve kategorileri saptamak, akımların birbirleriyle bağlantılı ilişkilerini ortaya koymak ve bunların doğurganlık üzerindeki etkilerini tartışmak amaçlanmıştır. Araştırma sonuçları; antinatalizm etiketli paylaşımlarda üreme, katastrofi, tahammülsüzlük, düşünce/politika, rıza, kapitalizm ve bireyselleşme kategorilerine işaret etmiştir. Ayrıca antinatalizm ve çocuksuzluk akımlarının doğurganlık üzerinde benzer etkiye sahip oldukları; yine de bireylerce farklı düşünsel süreçlerin sonucunda ortaya çıktığı bulgulanmıştır.

Published: October 2022

This work presents and values a model of complementary activity to the students training based on monographic works carried out from the analysis and review of scientific publications. This model promotes an extra motivation in those students with a real interest in learning beyond the basic content included in the subject program. In most cases, this proposal generates an important attraction when facing a type of unknown information.Firstly, a basic introduction to the problem is developed; after that, a selection of a coherent number of articles or communications is done, analysing the key contributions on the subject at hand; and finally, conclusions are stated. Exceptionally, it is proposed that students add a section including real cases observed in their daily environment (e.g., new products, pathologies and damages, execution systems).

Published: October 2022

Large number of unfilled teaching positions in rural regions is a common problem in most of the countries, including Azerbaijan. In this paper, we try to identify factors affecting preferences of teachers on workplace and thus, the reasons for not choosing schools in rural areas and propose an incentive mechanism to reduce number of unfilled vacancies in these regions of Azerbaijan. To understand the factors affecting student preferences, wesurveyed around 2000 junior students majoring in various education programs in different universities. Based on the survey results, we identify the factors affecting the decisions of the prospective teachers and the barriersthat keep them away from choosing schools in rural areas. Based on our findings, we propose an incentive mechanism to fulfil the vacancies in rural area schools.

Published: October 2022

Construction stakeholders plan to guarantee the success of projects. Still, the results frequently are different in quality, time, or costs. The disruptions are frequent, and the stakeholders must be ready to react promptly to changes while keeping competitiveness and sustainability. This goal requires proper construction education. Based on diverse civil engineering and architecture programs, the article evaluates if current construction education includes past knowledge, notions of sustainability, and global matters to allow its participants to identify challenges and risks, giving them the tools to act appropriately. The results show different construction education perspectives. Some are very advanced, and others are not. The Venezuelan case is a reference to link theory and practice in the construction sector. Incorporating critical analysis and comparisons with data and cases from diverse successes, disruptions, or errors is presented as education innovation to support this industry's competitiveness and sustainability.
The Otway Forester Strepera graculina ashbyi: A neglected and misunderstood subspecies of the Pied Currawong from southern Victoria
Authors:   Arthur Rylah Institute for Environmental Research, Department of Environment, Land, Water and Planning, 123 Brown Street, Heidelberg VIC 3084, Australia, Menkhorst Peter , Morley Craig
Published: October 2022

The most southerly of the six described subspecies of the Pied Currawong, Strepera graculina ashbyi, is perhaps the least known and most controversial. Because it has reduced areas of white at the bases of the primaries and at the bases of the rectrices, its appearance is superficially similar to the Grey Currawong S. versicolor, and this has caused confusion from the time of its first description to the present day. Subspecies ashbyi is considered to be extinct by some authorities, yet our observations indicate that birds showing the phenotypic characteristics of ashbyi are common breeding residents in the Otway Ranges of southern Victoria and in the regional city of Geelong and surrounding areas. Here we review the taxonomic history, morphological characteristics and current status of S. g. ashbyi. We identify errors of citation and misinterpretation of the literature which, combined with a lack of ground-truthing, have resulted in the classification of a seemingly common taxon as Extinct. We then present a re-assessment of the distribution and biogeography of S. g. ashbyi and discuss the suitability of the type specimen. The true taxonomic status of S. g. ashbyi can probably only be determined by studies of rates of genetic introgression amongst Pied Currawong populations across western Victoria, but in the meantime its conservation status should be revised to Least Concern.

This study reports on a successful trial of a double-tag mounting protocol using both satellite and GPS tags on captive black-cockatoos (Forest Red-tailed Black-Cockatoo Calyptorhynchus banksii naso, Baudin’s Black-Cockatoo Zanda baudinii and Carnaby’s Black-Cockatoo Z. latirostris). The aim of the study was to assess the feasibility and tolerance of a novel back-mount and a double-mount protocol combining a back- and tail-mount in black-cockatoos. We trialled solar 3D Global Positioning Systems (GPS) tags, standard solar and battery-operated GPS and Platform Terminal Transmitter (PTT) tags, and developed an attachment method to fit back-mounted solar-powered UvA-BiTS GPS tags to captive black-cockatoos. We investigated the effect of a variety of different types of tail-mounted satellite tags on the operational ability of the primary UvA-BiTS units and the feasibility of the double-mounted tag system with regard to tolerance by the birds. Our study determined that the combination of a 7.5-g UvA-BiTS GPS tag and 17-g Telonics TAV 2617 satellite tag was best tolerated by the birds and was the optimal tag system for use on birds to be released. This system enables capture of movement data to better understand the ecology of black-cockatoos, and identify critical feeding, roosting and breeding habitats, thereby informing conservation management initiatives to conserve these threatened species.

Published: October 2022

Background:

As health care transitions toward value-based care, orthopaedics has started to implement time-driven activity-based costing (TDABC) to understand costs and cost drivers. TDABC has not previously been used to study cost drivers in anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to use TDABC to (1) calculate bone-tendon-bone (BTB) and hamstring ACLR total costs of care and (2) evaluate the impact of graft choice and other factors on ACLR costs.

Methods:

Data were collected from electronic medical records for primary ACLR from the institutional patient-reported outcome registry between 2009 and 2016 in 1 ambulatory surgery center. Patients receiving allograft, revision ACLR, or concomitant meniscal repair or ligament reconstruction were excluded. The total cost of care was determined using TDABC. Multivariate regression analysis was conducted between ACLR cost and group characteristics.

Results:

A total of 328 patients were included; 211 (64.3%) received BTB autograft and 117 (35.7%) received hamstring autograft. The mean cost was $2,865.01 ± $263.45 (95% confidence interval: $2,829.26, $2,900.77) for BTB ACLR versus $3,377.44 ± $320.12 ($3,318.82, $3,436.05) for hamstring ACLR (p < 0.001). Operative time was 103.1 ± 25.1 (99.7, 106.5) minutes for BTB ACLR versus 113.1 ± 27.9 (108.0, 118.2) minutes for hamstring ACLR (p = 0.001). The total implant cost was $270.32 ± $97.08 ($257.15, $283.50) for BTB ACLR versus $587.36 ± $108.78 ($567.44, $607.28) for hamstring ACLR (p < 0.001). Hamstring graft (p = 0.006) and suspensory fixation on the femoral side (p = 0.011) were associated with increased costs.

Conclusions:

The mean cost of care and operative time for BTB autograft ACLR are less than those for hamstring autograft ACLR. Operative time, implant choice, and graft choice were identified as modifiable cost drivers that can empower surgeons to manage primary ACLR costs while maximizing the value of the procedure.

Objective
To determine the distribution of different types of arrhythmia and immediate outcome in children presenting in emergency department of a tertiary care hospital.
Study Design:
An observational analytical cohort study.
Place and Duration:
The department of cardiology, National Institute of Cardiovascular Diseases (NICVD), Karachi from January 2022 to July 2022.
Methodology:
A total of 91 children of both genders aged 1 day to 18 years presenting with one or more of the following symptoms: chest pain, bradycardia, tachycardia and/or syncope and diagnosed as cases of arrhythmia were included. Detailed medical history and information about demographic and clinical parameters were obtained. Complete general and cardiac examinations including 12 leads ECG, 2-D Echo study and the holter study for those with unexplained arrhythmias, syncope were performed. Distribution of arrhythmia types and immediate treatment outcomes were noted.
Results
In a total of 91 children, 46 (50.5%) were male. The mean age was 8.13 ± 4.45 year. Palpitation and chest pain were the commonest presenting symptoms reported in 87 (95.6%) and 25 (27.5%) children respectively. Acyanotic CHDs were found in 29 (31.9%) children. Supraventricular tachycardia (SVT) was observed to be the most frequent type of arrhythmias noted in 31 (34.1%) children while atrial fibrillation and ventricular tachycardia were the other most common arrhythmias noted in 19 (20.9%) and 15 (16.5%) children respectively. Amiodarone was the most frequent choice of treatment that responded well in 35 (38.5%) children and was mainly utilized in children with supraventricular tachycardia. Propranolol responded well in 34 (37.4%) children. Mean duration of hospital stay was 4.55 ± 3.32 days while mortality was noted in 4 (4.4%) children.
Conclusion
Palpitation and chest pain were the commonest presenting symptoms among children with arrhythmias. Supraventricular tachycardia, atrial fibrillation and ventricular tachycardia were the other most frequent types of arrhythmia. Overall outcome of arrhythmias treatment was good.

Background In abdominal surgery, ultrasound-guided anterior quadratus lumborum blocks (QLB) are performed for inducing analgesia. However, no study reported the suitable volumes of the anterior QLB for the different postoperative analgesia regions. This prospective randomized controlled study assessed the dermatomal spread and analgesic effects of the three different volumes of a local anesthetic for anterior QLB. Methods Ultrasound-guided anterior QLB was performed at the L2 level on 30 healthy volunteers. The participants were randomized to receive 20 ml (n = 10), 30 ml (n = 10) and 40 mL (n = 10) of 0.375% ropivacaine. The cutaneous sensory blocked area (CSBA), the number of block dermatomes, and the block duration time were measured by determining the extent of the cold sensation. Results The CSBA was significantly larger in the 40 ml group than the 30 (P = 0.001; 1350.6 ± 234.4 vs 1009.5 ± 151.6 cm2) and 20 ml groups (P < 0.001; 1350.6 ± 234.4 vs 808.1 ± 120.5 cm2). Similarly, the number of blocked dermatomes was significantly higher in the 40 ml group than in the 30 and 20 ml groups. No significant difference was observed in block duration among the groups. Conclusions No difference was observed in block duration with the various volumes of 0.375% ropivacaine. However, the larger volume for anterior QLB contributed to a larger area of cutaneous sensory blockade. Appropriate volumes in anterior QLB can create suitable postoperative analgesia levels for the different operative sites. Trials Registration: The study was registered in the Chinese Clinical Trial Registration Center on www.chictr.org.cn on 27 April 2018 (registration number: ChiCTR-IOR-17010853).
Pyro-Velocity: Probabilistic RNA Velocity inference from single-cell data

Published: October 2022

Single-cell RNA Velocity has dramatically advanced our ability to model cellular differentiation and cell fate decisions. However, current preprocessing choices and model assumptions often lead to errors in assigning developmental trajectories. Here, we develop, Pyro-Velocity, a Bayesian, generative, and multivariate RNA Velocity model to estimate the uncertainty of cell future states. This approach models raw sequencing counts with the synchronized cell time across all expressed genes to provide quantifiable and improved information on cell fate choices and developmental trajectory dynamics.

In this study, the db/db mices that met the model standard were randomly divided into model control group, drug group and normal control group of m/m mice of the same age. The model control group and normal control group were given10.0ml kg-1 drinking water by gavage, and the drug group was gavaged by 1.0g kg-1the bamboo shoot biochar, once a day in each group. The results showed that compared with the model group, the blood glucose level of db/db diabetes mice was decreased after 6 weeks by gavage with bamboo shoot biochar, and the levels of GSP, FFA, LEP and AGEs in serum decreased to varying degrees, while INS increased significantly. The antioxidant activities of SOD, GSH-PX and CAT in kidney were increased in varying degrees. The gut community structure in fresh contents of ileocecal region was significantly changed. At the Phylum level, compared with the normal control group, the relative abundance of Bacteroidota and Actinobacterota in the model group was significantly reduced, while the relative abundance of Firmicutes and Proteobacteria was significantly increased. Compared with the model group, the relative abundance of Bacteroidota and Proteobacteria in the drug group decreased significantly, while the relative abundance of Firmicutes and Actinobacterota increased significantly. At the genus level, compared with the normal control group, the relative abundance of norank_f_Muribaculaceae, Desulfovibrio, Enterrhabdus, Odoribacter, Bifidobacteriumin the model group decreased significantly, while the relative abundance of Turicibacte and norank_f_Lachnospiraceae, Romboutsia, unclassified_f_Lachnospiraceaeincreased significantly. Compared with the model group, the relative abundances of norank_f_muribaculaceae, Bacteroides and Romboutsiain the drug group decreased significantly (P<0.01), while the relative abundances of Lactobacillus, Desulfovibrio, Enterhabdus, Bifidobacterium and Turicibacter increased significantly (P<0.05-0.001).

Published: October 2022

Chemoimmunotherapy is the treatment of choice for some advanced progressive cancers, but it is only effective in a small subset of patients. Transcriptional upregulation of isocitrate dehydrogenase 3α (IDH3α) promoted cancer progression through metabolic reprogramming. Here, we demonstrated that IDH3α is elevated in uterine cervical cancer (UCC) and non-small cell lung cancer (NSCLC) patient samples and promotes epithelial-mesenchymal transition (EMT) in cervical cancer cells. Silencing IDH3α inhibited α-ketoglutarate production and glycolysis and reduced lactate release. In addition to regulating the acidic microenvironment, IDH3α activates the cGAS-STING pathway after treatment with cisplatin and programmed cell death ligand 1 (PD-L1) antibody in vivo and promotes CD8 + T cell infiltration and cytokine release. In conclusion, our data demonstrated that silencing IDH3α sensitizes chemoimmunotherapy by modulating the acidic microenvironment and activating the cGAS-STING pathway, which aims to improve the efficacy of chemoimmune-based combination therapy for patients with limited resistance.

Published: October 2022

Objective
Musculoskeletal discomfort is a health problem prevalent among dentists which negatively affects their daily living activities. Dentistry is a profession that requires great precision and concentration, and it is generally associated with a high prevalence of musculoskeletal disorders. The purpose of this study was to determine the musculoskeletal symptomatology of the back and neck associated with the level of postural risk in dentist’s work.
Methodology
In this cross-sectional observational study, 187 dentistry from the cities of Palmira and Neiva were included. The researchers applied a validated questionnaire, the Nordic Kuorinka questionnaire and the Rapid Entire Body Assessment (REBA) method through recordings and photographs; additional questions were included considering the total duration of work experience in dental practice. Qualitative variables were analysed using proportions to determine the prevalence of neck and back musculoskeletal symptomatology, whereas quantitative variables were analysed using central and dispersion tendency measures. An ordinal logistic regression was applied to show the relationship between musculoskeletal symptomatology and the level of postural risk of the REBA method.
Result
Results show 71.1% prevalence of back musculoskeletal symptomatology and 60% prevalence of neck symptomatology. Dentists were affected when performing their activities in the last 12 months due to musculoskeletal discomfort in the back (58.2%) and neck (17.2%). The possible causes of these discomforts were distributed as follows: 35.9% was claimed to long working hours and 23.5% to bad posture. The REBA score indicates an average level of postural risk with a prevalence of 59.8%. A statistically significant relationship between prolonged time at the workplace was identified (odd ratio = 1.3; p = 0.03; 95% confidence interval = 1.1–2.9) with the average postural risk level of the REBA method between bad posture (χ2 = 48.41; p = 0.000).
Conclusion
The study determined a high prevalence of musculoskeletal symptomatology in the neck and back and a score level of the REBA method equivalent to the average risk level; that is why, task changes may be required. Occupational health education programs could be effective in reducing these discomforts.
