Application of Asaoka’s Method in Multistage Triaxial Compression Testing of Normally Consolidated Soils
Authors: Lijith K. P. , Robinson R. G.
Published: October 2024

Determination of shear strength parameters becomes a challenge when it is difficult to retrieve a minimum of three identical undisturbed soil specimens. In such a situation, multistage triaxial compression testing can be adopted using a single specimen. Multistage triaxial testing involves stage-wise consolidation and shearing at three confining pressures without the failure of the specimen until the last stage. A critical issue associated with multistage triaxial testing is the estimation of ultimate deviator stress and the corresponding pore pressure as the specimen was not allowed to reach failure in each stage. Conventionally, the failure stress state in each stage is computed by extrapolating the stress–strain and pore pressure–strain data to a finite strain by employing Kondner’s rectangular hyperbola model. However, it is reported in the literature that the aforementioned method often overestimates the deviator stress and pore pressure values. In this context, the present study investigates the suitability of Asaoka’s observational procedure for predicting these values at failure state. The validity of the proposed procedure is verified by comparing the ultimate deviator stress and pore pressure values obtained by analyzing the stress–strain data collected from the literature and by performing multistage triaxial testing on three reconstituted soil samples with that of the rectangular hyperbola method. From the results, it was observed that Asaoka’s method is more suited for predicting the shear strength parameters. It is believed that the proposed methodology would aid in obtaining the shear strength parameters of a soil from a single specimen by conducting multistage triaxial testing.

Published: October 2024

A new three-axis loading frame has been developed to enable real-time visualization of in-situ soil and rock structure interactions via X-ray tomography during small-scale model testing. The constructed frame is capable of performing a wide range of small-scale 1g tests and can accommodate monotonic and cyclic actuation under both load and displacement control. The compact size of the system enables remote multi-axis operation from within an X-ray cone-beam scanning bay, a capability which is owed to a comprehensive design process. Design and fabrication involved a blend of physical and numerical experiments to assess suitable construction materials and performance. In this scope, the new equipment is discussed and its capability is showcased.
An Indirect Pathway from the Rat Interstitial Nucleus of Cajal to the Vestibulocerebellum Involved in Vertical Gaze Holding
Authors: Sugimura Taketoshi , Miyashita Toshio , Yamamoto Mariko , Kobayashi Kenta , Yoshimura Yumiko , Saito Yasuhiko
Published: October 2024

The neural network, including the interstitial nucleus of Cajal (INC), functions as an oculomotor neural integrator involved in the control of vertical gaze holding. Impairment of the vestibulocerebellum (VC), including the flocculus (FL), has been shown to affect vertical gaze holding, indicating that the INC cooperates with the VC in controlling this function. However, a network between the INC and VC has not been identified. In this study, we aimed to obtain anatomical evidence of a neural pathway from the INC to the VC (the INC-VC pathway) in rats. Injection of dextran-conjugated Alexa Fluor 488 or adeno-associated virus 2-retro (AAV2retro) expressing GFP into the FL or another VC region (uvula/nodulus) did not reveal any retrogradely labeled neurons in the INC, suggesting that INC neurons do not project directly to the VC. Rabies virus-based transsynaptic tracing experiments revealed that the INC-VC pathway is mediated via synaptic connections with the prepositus hypoglossi nucleus (PHN) and medial vestibular nucleus (MVN). The INC neurons in the INC-VC pathway were mainly localized bilaterally within the rostral region of the INC. Transsynaptic tracing experiments involving the INC-FL pathway revealed that INC neurons connected to the FL via the bilateral PHN and MVN. These results indicate that the INC-VC pathway is not a direct pathway but is mediated via the PHN and MVN. These findings can provide clues for understanding the network mechanisms responsible for vertical gaze holding.
Poisson manifold
Authors: Cattafi Francesco
Published: October 2024

In differential geometry, a field in mathematics, a Poisson manifold is a smooth manifold endowed with a Poisson structure. The notion of Poisson manifold generalises that of symplectic manifold, which in turn generalises the phase space from Hamiltonian mechanics. A Poisson structure (or Poisson bracket) on a smooth manifold M {\displaystyle M} is a function { ⋅ , ⋅ } : C ∞ ( M ) × C ∞ ( M ) → C ∞ ( M ) {\displaystyle \{\cdot ,\cdot \}:{\mathcal {C}}^{\infty }(M)\times {\mathcal {C}}^{\infty }(M)\to {\mathcal {C}}^{\infty }(M)}on the vector space C ∞ ( M ) {\displaystyle {\mathcal {C}}^{\infty }(M)} of smooth functions on M {\displaystyle M}, making it into a Lie algebra subject to a Leibniz rule (also known as a Poisson algebra). Poisson structures on manifolds were introduced by André Lichnerowicz in 1977[1] and are named after the French mathematician Siméon Denis Poisson, due to their early appearance in his works on analytical mechanics.[2]
Could We Prevent Tobacco Products in Young Populations?
Authors: Zmak Maja
Published: October 2024

The well-documented detrimental effects of tobacco on children and adolescents make it imperative to prevent tobacco use in young populations, which is a critical public health objective. Youth are particularly susceptible to nicotine’s addictive properties, and they are more susceptible to developing an addiction to tobacco products if they begin using them at a young age, according to research. The reduction of tobacco use among young people can be achieved by implementing evidence-based strategies, including increasing the minimum legal age for purchasing tobacco products, increasing taxation on these products, restricting marketing aimed at youth, and facilitating comprehensive school-based prevention programs, etc. Furthermore, prevention initiatives may be further bolstered by initiatives to encourage smoke-free environments and offer access to smoking cessation resources. In order to effectively prevent tobacco use in young populations and promote healthier outcomes for future generations, it is necessary to target various levels of intervention and involve multiple sectors, including healthcare professionals, educators, policymakers, and community leaders.

El Greco y el punto de vista: la capilla Ovalle de Toledo
Authors: Marías Franco Fernando
Published: October 2024

La capilla de Isabel de Ovalle, en la parroquia de San Vicente Mártir de Toledo, es una de las últimas obras de El Greco en las se enfrentó con el diseño de un retablo y la pintura de los lienzos y la decoración de la capilla, en función de la estructura arquitectónica de la capilla parroquial. Nuevos documentos -en los que entre otras cosas se identifica el tema del lienzo principal como una "Inmaculada Concepción" en lugar de la "Asunción"- y planos arquitectónicos contemporáneos de la iglesia y capilla permiten una nueva aproximación al conjunto; una obra en la que reaparece el problema de la localización de un retablo en relación con la peculiar concepción del pintor relativa al punto de vista del que se tenía que contemplar una obra de arte. El análisis de todo este material lleva a una discusión acerca de este problema central de la teoría y la práctica del arte en la Europa del siglo XVI; un problema básico conectado con temas como la perspectiva y su punto de vista preferencial, la arquitectura y las condiciones óptimas para la visión de una obra.
Los dibujos wagnerianos de Egusquiza existentes en la Biblioteca Nacional de Madrid
Authors: Carmena de la Cruz Patricia
Published: October 2024

Hacia 1876, la afición a la música y la literatura llevan al pintor de asuntos de género y retrato, Rogelio de Egusquiza (1845-1915), a entrar en contacto con el wagnerismo y entablar amistad con el compositor alemán Ricardo Wagner. A partir de ese instante, su vida y obra se transforman, dando lugar a una última etapa pictórica -más personal-, dominada por la iconografía wagneriana. Su obra -ajena al gusto imperante en España -sólo puede comprenderse por su estrecha vinculación al mundo francés y, muy especialmente, a la capital parisina, donde residió la mayor parte de su vida. Los dibujos presentados en el artículo, pertenecen a esta última etapa. Se trata de estudios realizados para los aguafuertes y la tercera y última serie de óleos de este tema que el autor donó a la Biblioteca Nacional de Madrid.
Los autores españoles de los tratados "De Re Military", Fuentes para su conocimiento: los Preliminares
Authors: Merino Peral Esther
Published: October 2024

Uno de los rasgos fundamentales de los autores españoles, de los siglos XVI y XVII, sobre teoría del "Arte Militar" era su extracción nobiliario-castrense. Veteranos de las distintas campañas emprendidas por los Habsburgo castellanos, ocupados como escritores ocasionales, para exponer sus propias experiencias sobre la guerra o las utopías que proponían para mejorar los últimos resultados, que eran las victorias en los campos de batalla. Gracias a su labor literaria, a los contenidos de estos tratados militares, en su amplia mayoría centralizados desde la Corte de Madrid, podría hablarse de un "Humanismo Militar", o de un Renacimiento del Arte Militar en la Península Ibérica.

Algunos datos para la historia del Palacio de Vista Alegre en Carabanchel Bajo
Authors: Díaz Miguez Daniel
Published: October 2024

Entre las muchas posesiones de la familia real en el siglo XIX ha habido una que ha pasado prácticamente desapercibida: la de Vista Alegre, en Carabanchel Bajo. Fue una finca de recreo, similar a la que muchas familias aristocráticas tenían en las afueras de Madrid. Iban allí María Cristina y sus hijas a descansar, a disfrutar de una vida bucólica, cercana a la naturaleza. Cuándo y cómo llegó a sus manos tal finca lo ignoramos, pero aportamos unos planos ciertamente interesantes, pues por ellos conocemos su magnitud, los distintos tipos de construcciones campestres, los diversos juegos al aire libre... y nos podemos hacer una idea más clara del tipo de vida que llevaban. A través de la documentación aportada, entrevemos la autoría de Martín López Aguado, la intervención de Pascual y Colomer y las distintas reformas que ha debido haber a lo largo de la historia de la finca (sin meternos en la reforma de este siglo para habilitar el nuevo palacio en Centro de Reeducación de Inválidos). Conocemos mejor el funcionamiento de la Real Casa y del Patrimonio, y observamos los gastos e ingresos que obtenían de lo cultivado en esta posesión. Posteriormente, la finca fue comprada por el Marqués de Salamanca quien, al morir, dejó cuantiosas deudas, por lo que el edificio pasó a ser posesión del Estado (actualmente de la Comunidad de Madrid).
Improving Admission Temperature in Infants ≥34 Weeks’ Gestation: A Quality Improvement Initiative
Authors: Lawrence Sarah Linda , Nguyen Laura , Sucha Ewa , Lemyre Brigitte , Mitsakakis Nicholas
Published: October 2024

BACKGROUND

NICU admission for hypothermia is a problem worldwide, with associated morbidity, mortality, and financial costs. Many interventions have been studied for smaller infants, but there has been little focus on infants born ≥34 weeks’ gestational age (GA), though most deliveries occur at this gestation. Our primary aim was to improve the proportion of infants ≥34 weeks’ GA with normal NICU admission temperature. Secondary outcomes included improvement of the proportion of normal first temperature in all infants ≥34 weeks’ GA, independent of NICU admission, and improvement of predefined outcome measures.

METHODS

We completed a root cause analysis, using fishbone and process mapping to determine what factors were contributing to hypothermia. A series of changes were trialed using plan-do-study-act cycles to develop a standard operating procedure, covering both vaginal and cesarean section births. Outcome measures were analyzed using a P-chart as well as traditional statistical tests.

RESULTS

We successfully increased the proportion of infants ≥34 weeks’ GA with normothermia on NICU admission from 62% to 80% without increasing hyperthermia. In addition, the interventions improved the proportion of delivery room normothermia in all infants born ≥34 weeks’ GA and were associated with a decreased need for intravenous therapy for hypoglycemia and the incidence of metabolic acidosis.

CONCLUSIONS

This quality improvement initiative was successful at improving our institution’s rates of normal infant temperature. The methodology used can be applied to other similar centers to improve this common problem.

Authors: Laskowska-Wronarowicz Anna , Olszewska-Turek Katarzyna , Micek Agnieszka , Bętkowska-Korpała Barbara
Published: October 2024

Introduction: The severity of depression symptoms in COVID-19 patients differs among populations investigated and changes over time. Increasing evidence supports the hypothesis about the involvement of inflammation in the development of depression. Methods: A systematic review and a meta-analysis of the cross-sectional and cohort studies published between 2019 and 2023 were conducted according to the PRISMA criteria. The outcomes of interest were the proportions of mild, moderate, and severe depression symptoms during and after hospitalisation, and associations between depression and inflammation in COVID-19 patients. Results: Thirty articles were included in the systematic review. In the quantitative meta-analysis, the overall proportions of moderate-to-severe and mild-to-severe depression were estimated at 0.21 (95% CI: 0.13–0.31) and 0.35 (95% CI: 0.23–0.48), respectively. The fixed effects model of the meta-analysis of inflammatory markers showed a difference between COVID-19 patients with and without depression, with higher concentrations of both C-reactive protein and neutrophil-lymphocyte ratio detected among people suffering mood disturbances. However, in random effects models, findings for C-reactive protein lost significance, and for neutrophil-lymphocyte ratio were on the boundary of significance (p = 0.053). Conclusions: According to the study results, the proportion of depression decreases over time after a COVID-19 diagnosis. The relationship between depression and inflammation is still uncertain and requires further research.

Authors: Malik Rajdeep , Ali Nazreen , Meena Jagram
Published: October 2024

Copper oxide particles have a significant role in various fields due to their many properties like special shape, size, and high surface area. Due to their rarity and unique characteristics, such as their large surface area, paramagnetic nature, and ease of separation, Copper oxide nanoparticles have received the greatest attention. Chitosan, Guar Gum, Tamarind, Alginate, starch, cellulose, polysaccharide, etc. are examples of natural biopolymers that have proven to be excellent hosts for the creation of CuO nanoparticles. Long-established fabrication techniques for biopolymer-based CuO nanocomposites include co-precipitations, green synthesis, Solvent Casting Method, Alco thermal method, and Sol-Gel methods. Excellent biological characteristics of Copper oxide/biopolymer nanocomposites include their potent antibacterial activity against a variety of diseases as well as bacteria that are resistant to antibiotics. These characteristics have sparked the creation of numerous strategies with direct biological applications, including customized surfaces with antimicrobial effects, wound dressings, and modified textiles. This study aims to provide the very first biopolymer CuO nanoparticles to be reported in the previous ten years as well as its appealing methodology in diverse applications.

Published: October 2024

At the end of the 20th century, the term discourse, which was justified by European linguists, gained relevance in modern linguistics and gave rise to wider research. The ideas about the discourse in the scientific literature have given impetus to each other and facilitated a wider analysis of this term. In Azerbaijani linguistics, this topic is considered a younger field of science. From this point of view, we decided to conduct research in the mentioned direction. In the article, the types of discourse from the point of view of both structure and functionality, and the problems of its comparison with the text are considered.

Published: October 2024

ABSTRACT BACKGROUND: Chile presents one of the lowest organ donation rates, resulting in pediatric liver waitlist mortality rates up to 38.1%. Live donor liver transplantation is one of the main alternatives to decrease waitlist mortality, mostly utilized in our country for small children up to 20 kg. AIMS: The aim of this study was to report a three-case series of adult-to-pediatric living donor liver transplantation using a full left lobe graft. METHODS: We report three cases of children with more than 20 kg who received complete left hemi-grafts in different clinical scenarios. The indications and techniques adopted are discussed. RESULTS: Three children, two girls and one boy, aged 11, 7, and 3 years, were transplanted. The indications for transplant were fulminant hepatitis of autoimmune etiology, hepatoblastoma, and chronic liver failure due to autoimmune hepatitis, respectively. The evolution was satisfactory in all three children, and to date, all are well, approximately 12–24 months after the transplant. CONCLUSIONS: The use of a living donor left lateral segment (segments 2 and 3) has been successfully employed in pediatric liver transplantation. However, it is only suitable for infants and low-weight children. This approach using the whole left hemi-liver graft contributes to the reduction of small-for-size syndrome, mortality rate, and waiting times associated with deceased donors.

Published: October 2024

Abstract The aim was to test a predictive model for the life satisfaction of students in their final years of Elementary Education, considering risk predictors (exposure to violence and discrimination) and protective predictors (social skills, perception of social support, and sense of community), as well as the gender variable. Participants were 709 students who attended the 7th, 8th, and 9th grades of public schools in the state of Rio de Janeiro. Regression analyses indicated a final model, which explained 23% of the variability in life satisfaction. The data showed that personal, relational, and contextual resources function as protective factors for life satisfaction and can be promoted in interventions with students at the end of Elementary Education.

Abstract This study evaluated the effect of actives present in conventional and desensitizing mouth rinses on the control of dentin erosive tooth wear. Two hundred and seventy dentin specimens from human molars were prepared. The specimens were randomly allocated into 10 experimental groups (n=10): 4 corresponding to desensitizing mouth rinses, 4 to conventional mouth rinses, a negative control group (C-: distilled water), and a positive control group (C+: 500 ppm fluoride plus 800 ppm tin mouth rinse). Specimens were subjected to an erosion-abrasion cycling model: 5 min immersion in 0.3% citric acid and 60 min exposure to artificial saliva. This procedure was repeated 4x/day for 5 days. Immediately after the first and last erosive challenges, the specimens were brushed with a slurry of fluoride toothpaste for 15 s, with a total of 2 min exposure to the slurry. Afterward, the specimens were exposed to the mouth rinses. Dentin surface loss (SL, in µm) was determined by optical profilometry. Data were statistically analyzed by using Kruskal-Wallis and Dunn's tests (α=0.05). The only mouth rinses that presented significantly lower dentin SL than the C- was a desensitizing one containing sodium fluoride (220 ppm F-) with dipotassium oxalate (1.4%) and the C+ (p<0.001 and p=0.013, respectively), without significant differences between them (p>0.05). Dentin SL of the other groups did not significantly differ from the C- (p>0.05). The combination of sodium fluoride with dipotassium oxalate in a desensitizing mouth rinse showed a promising result against dentin erosive wear, matching the protection offered by a fluoride/tin mouth rinse.

Published: October 2024

Abstract This study aimed to evaluate the effects of different scaling protocols on the morphology and roughness of the root dentin substrate exposure to ionizing radiation. One hundred and thirty extracted bovine incisors were randomly divided into two groups (n=65): non-irradiated (NIR) and irradiated (IR). Each group was initially subdivided into three subgroups according to the type of non-surgical periodontal protocol: NIT: no instrumentation; HS: hand scaling with 15 apical-coronal instrument movements; US: ultrasonic scaling with 15 apical-coronal cycles. Subsequently, all samples were subjected to the prophylaxis protocol, being subdivided into the following groups: NIT/PP: prophylaxis with a fine prophylactic paste using a rubber cup for 15 seconds; HS/PP: Hand scaling followed by the prophylaxis protocol; US/PP: Ultrasonic scaling followed by the prophylaxis protocol. The roughness of the root dentin surface was measured with a profilometer (Ra/Rz - μm), and the morphology of the dentin surfaces was analyzed using scanning electron microscopy (SEM). The analyses were conducted before and after the prophylaxis protocol. In the absence of prophylaxis, the roughest surfaces were observed after ultrasonic instrumentation followed by hand instrumentation for both IR and NIR groups. No difference in Ra and RZ values between HS/PP and US/PP was observed for both substrates. For the IR group, the prophylaxis resulted in similar Ra and RZ values for both instrumentation groups in comparison to no instrumentation. Ordinal logistic regression showed that both HS and US resulted in higher scores than NIT, irrespective of IR presence. In conclusion, the IR showed a rougher root surface for both HS and US in comparison to NIR. However, the prophylaxis procedure significantly reduced the roughness of root surfaces after both instrumentation procedures

Abstract Periodontal bone loss is potentiated by diabetes. Despite the beneficial anti-inflammatory and antiresorptive effects of Atorvastatin (ATV) on periodontitis, it has been reported to increase the risk of diabetes, which may modify the course of periodontal disease. Therefore, this study aimed to evaluate the effect of ATV on alveolar bone in rats with periodontitis and diabetes. For this, 72 Wistar rats were divided into groups: Naïve (N) not submitted to any procedure; Experimental periodontitis (EP) group submitted to ligature-induced periodontitis; diabetes mellitus (DM), submitted to EP and receiving single dose of streptozotocin (60 mg/kg, i.p.) after 12 hours of fasting; and ATV DM, submitted to EP and DM and receiving orally 27 mg/kg of ATV, 30 minutes before ligature placement, and continued daily until the 11th day. Animals from EP and DM received saline solution 0.9% as placebo. Glycemic levels measured in all animals and then were euthanized. Maxillae were collected for macroscopic, micro-tomographic, and microscopic analyses. DM caused intense bone loss (60%), characterized by a reduction in trabecular thickness and bone volume. DM reduced osteoblasts, increasing osteoclast counts, and induced an inflammatory infiltrate in the periodontium. ATV was found ineffective in protecting bone in diabetic rats, exacerbating bone loss by 21%. Additionally, ATV significantly increased blood glucose levels. In summary, ATV did not prevent alveolar bone loss or modulate inflammation in DM animals undergoing EP. ATV also increased blood glucose levels in these animals. Therefore, the systemic use of ATV in uncontrolled diabetic conditions should be carefully evaluated.

ABSTRACT: The mango tree presents a high level of fruit abscission, which is increased in semiarid regions due to environmental stress. The use of biostimulants and phytoregulators has shown to be a promising strategy to improve fruit setting. Thus, the present study defined the best strategy for setting and development of the fruit, with the application of phytoregulators and biostimulants on the ‘Keitt’ mango tree, cultivated in the São Francisco Valley. Two experiments were performed. In experiment 1, a randomized block design was used, with four treatments T1: control, T2: gibberellic acid (AG3) + 2,4-dichlorophenoxyacetic acid (2,4-D), T3: AG3 + 2,4-D+Benzyladenine, T4: Biostimulant + CoMo® (sources of cobalt and molybdenum). In experiment 2, the factorial scheme (2 ×3 + 1) distributed in randomized blocks was established, corresponding to two forms of potassium fertilization (recommended and adjusted), three gibberellin concentrations (0, 10 and 20 mg L-1) and additional treatment (control - recommended potassium fertilization and no setting strategy). The variables analyzed include the relative number of fruits, the number of fruits for domestic and foreign markets, productive potential, production, productivity, fruit volume, fruit mass, and the yield of peel, pulp and stone. The application of 10 mg L-1 AG3 + 10 mg L-1 2,4-D + 10 mg L-1 Benzyladenine in full flowering of the ‘Keitt’ mango tree, increased the setting and the production of the fruit. Regardless of fertilization, sequential applications at 10 or 20 mg L-1 of AG3 proved to be an effective strategy to produce ‘Keitt’ mango tree. Adjusted potassium fertilization and the application at 10 mg L-1 of AG3 promotes the production of fruits with greater mass and volume.

Published: October 2024

ABSTRACT Objective: This study aims to assess cost-effectiveness of caudal epidural block with transforaminal nerve root block in the treatment of degenerative diseases of the lumbar spine. Methods: A total of 47 patients with lumbar sciatica symptoms were included. Low back pain and leg pain were assessed using the visual analogue scale (VAS), both in the pre-procedure and one week after. The cost-effectiveness and value required to improve each point on the VAS were estimated using addition, division, and rule of three calculations. Results: For low back pain, scores ranging from 2 to 10 were found before the procedure, with a mean of 7.5 ± 2.14 (95%CI: 6.8–8.1). A week after, these scores ranged from 0 to 10, with a mean of 3.1±2.8 (95%CI: 2.3–4.0; p < 0.0001). Regarding leg pain, scores ranging from 1 to 10 were noted before the procedure, with a mean of 6.8 ± 2.5 (95%CI: 6.1–7.4). A week after, these scores ranged from 0 to 9, with mean of 2.4 ± 2.5 (95%CI: 1.8–3.1; p < 0.0001). The cost of the materials used during the procedure was 214.72 BRL. Conclusion: Caudal epidural with transforaminal nerve root block were a cost-effective treatment modality for patients with degenerative diseases of the lumbar spine.

ABSTRACT Objective: This study aimed to evaluate the surgical treatment of diaphyseal femur fractures in polytraumatized children, considering consolidation rate, complications, and function as outcomes of interest. Methods: This is a quantitative, cross-sectional, and retrospective study of medical records of patients treated from 2012 to 2021. The 39 patients (41 femurs) were divided into four groups according to the method of osteosynthesis. We used the IBM SPSS Statistics software, version 20 (SPSS Inc, Chicago, IL), and performed Chi-square, Fisher, Kruskal-Wallis, and Shapiro-Wilk tests with a significance level of 5%. Results: We observed six complications among patients. Functional outcomes were satisfactory in 40 cases (97.6%) and unsatisfactory in one case (2.40%) according to the adopted criteria. We found one case (2.40%) of non-union and one case (2.40%) of malunion, whereas 39 cases (95.20%) achieved full consolidation. Conclusions: Flexible intramedullary nails and external fixators are the preferred options for patients aged 5 to 10 years. Intramedullary nails, plates, or external fixators are prioritized for patients over 11 years old. The type and pattern of fractures were considered relevant for treatment selection.

ABSTRACT Objective: To compare the prevalence of smokers among patients with chronic low back pain, in the presence and absence of Modic changes, also the correlation between smoking history and progression of the Modic scale. Methods: Observational study, case-control type, with the inclusion of 340 vertebral segments in a total of 68 patients, separated into groups: with Modic (case group) and without Modic (control group). The odds ratio between the groups was verified using the Chi-Square test. Degree of correlation between smoking history (packs/year) and the degree of disc degeneration using Max-Modic and Sum-Modic, using Spearman’s non-parametric test. Results: The Modic group (MG) was 54% female and 46% male, with an average smoking history of 13.84 pack-years and an average of 1.42 altered segments per patient. Conclusion: An increased risk for Modic changes was found among smoking patients (odds ratio [OR] 4.09; 95% CI, 1.26-12.31; p < 0.01) and significant correlation between Max-Modic, sum-Modic and smoking history.

ABSTRACT Objective: This study aims to describe a kinematic gait assessment protocol and identify its main alterations in individuals with cervical spondylotic myelopathy (CSM) compared to healthy patients. Methods: In total, 14 patients diagnosed with CSM were enrolled and submitted to a three-dimensional gait analysis. The movement of patients was captured with infrared emission cameras that identified tracking markers placed on the lower limbs. Reference positions were used, and the patients walked along a rubberized walkway. The Gait Profile Score (GPS) and Movement Analysis Profile (MAP) were used to analyze variables. Results were subjected to a Student’s t-test at 95% confidence interval. The R Core Team (2016) software was used for statistical analysis, graphically comparing the study results with data from healthy patients. Results: When comparing the kinematic data bilaterally, no statistical differences were found. However, graphical analysis showed changes in the gait of patients with CSM compared to healthy individuals. There were differences in all movements, with a more significant discrepancy in hip and knee flexion and extension, dorsiflexion and plantar flexion, and internal and external hip rotation. Conclusion: We describe a protocol for gait kinematics assessment using GPS and MAP, and we presented the differences in gait kinematics in patients with CSM compared to healthy individuals. Level of Evidence II, Prospective study.

Published: October 2024

ABSTRACT Objective: To evaluate the pregabalins adjuvant effect in patients with carpal tunnel syndrome (CTS) surgically treated, analyzing postoperative pain and the incidence of complex regional pain syndrome (CRPS). Methods: Outpatient surgical candidates with CTS were selected and followed for 12 months, divided into three groups. The Control Group received a placebo, the Pregabalin 75 mg Group received a daily dose, and the Pregabalin 150 mg Group received a daily dose of the medication. Patient progress was evaluated using the visual analog scale (VAS) for pain and the DN4 neuropathic pain score before surgery, one month and three months after. Results: The administration of pregabalin to surgical patients with CTS did not demonstrate significant differences in immediate postoperative pain relief. Additionally, there were no statistically significant variations in the incidence of complications, such as CRPS, among the groups. Conclusion: This study did not show a significant impact of pregabalin on postoperative pain relief or the reduction of CRPS incidence in patients undergoing surgery for CTS. These results suggest that pregabalin might not be an effective adjuvant in these surgical situations. Level of Evidence II, Comparative prospective study .

Resumo Pacientes com doença arterial periférica e aterosclerose generalizada apresentam alto risco de complicações cardiovasculares e nos membros, o que afeta sua qualidade de vida e longevidade. A doença aterosclerótica das extremidades inferiores está associada à alta morbimortalidade cardiovascular, sendo necessário para sua adequada terapia realizar o tratamento dos fatores dependentes do paciente, como a modificação no estilo de vida, e dos fatores dependentes do médico, como o tratamento clínico, tratamento endovascular ou cirurgia convencional. A abordagem médica para a doença arterial periférica é multifacetada, e inclui como principais medidas a redução do nível do colesterol, a terapia antitrombótica, o controle da pressão arterial e do diabetes e a cessação do tabagismo. A adesão a esse regime pode reduzir as complicações relacionadas aos membros, como a isquemia crônica que ameaça o membro e pode levar à sua amputação, e as complicações sistêmicas da aterosclerose, como o acidente vascular cerebral e infarto do miocárdio.
Performance determinants for agroindustrial projects in collective actions of small farmers
Authors: Perressim William Sbrama , Batalha Mário Otávio
Published: October 2024

Abstract The important economic and social role of agroindustrial collective actions does not eliminate the challenges related to the sustained feasibility of these enterprises. This article presents and discusses the main determinants that affect the performance and feasibility of collective agroindustrial projects, assessing the importance of each determinant for establishing the future performance of enterprises. A systematic literature review supported the structuring of the proposed analytical framework, which suggested the use of 24 determinants grouped into five factors. Afterwards, a panel of 20 experts used a multiple-criteria decision-making method, the Simple Multi-Attribute Rating Technique (SMART), to evaluate the relative importance of the determinants proposed by the model. The framework indicates the importance of each determinant on the performance of the collective agroindustrial projects, allowing the user to apply it with a decision-making tool. The proposed model combines and incorporates a wide number of sparse determinants in other works and highlights the factor “management, operation and finance” as a factor of success in making projects feasible.

Published: October 2024

Resumo Os colaboradores dos aviários integrados são componentes essenciais para o desenvolvimento do capital humano e social das organizações. O objetivo geral deste estudo foi identificar a política de gestão de pessoas adotada nas propriedades dos avicultores integrados vinculados à Associação de Avicultores na região de Dourados, MS, que utilizam o sistema de criação Dark House. Especificamente, durante a pesquisa, foram analisados o grau de comunicação organizacional entre colaborador e avicultor integrado e as condições de trabalho dos colaboradores nos aviários, além de identificados os fatores que influenciam o avicultor integrado a adotar uma política de gestão de pessoas nos aviários. A pesquisa caracteriza-se como quali-quanti, baseando-se na teoria do comportamento planejado (TCP) e na teoria do clima organizacional. Os resultados, a partir da TCP, indicam que os avicultores reconhecem a importância das políticas de gestão de pessoas, levando em consideração as opiniões da empresa integradora e de órgãos governamentais, mas relatam falta de apoio e capacitação para sua implementação. A pesquisa sobre o clima organizacional revelou que os aviários integrados carecem de políticas robustas de gestão de pessoas, evidenciando a necessidade de melhorias na comunicação e nas condições de trabalho.
CURRENT AND FUTURE NURSING IN PROMOTING PLANETARY HEALTH: ACTIONS FOR SUSTAINABLE DEVELOPMENT
Authors: Moraes Filho Iel Marciano de , Tavares Giovana Galvão
Published: October 2024

ABSTRACT Objective: to reflect on the current and future role of nursing in promoting Planetary Health. Method: theoretical-reflective study, based on documents related to the environmentalist theory of Florence Nightingale, reports from the World Health Organization, and articles retrieved from a PUBMED search using the controlled descriptors “nursing” and “Planetary Health.” Results: nursing, since Florence Nightingale’s environmentalist theory, recognizes the interconnection between human beings and nature. Evolving as a science, it offers independent and collaborative care to people of all ages, families, groups, and communities, regardless of health status, in various settings. The role of nursing goes further, addressing disparities and inequities in both local and global health. Nurses are essential in identifying and mitigating global impacts, promoting Planetary Health. Current and future professionals must focus on prevention, increasing the resilience of patients and communities to climate challenges, thus contributing to the progress of global health. Conclusion: planetary nursing, due to its social influence, is a strong ally in mitigating and changing the population’s paradigm regarding environmental impacts and the necessary adaptive changes, as long as it applies the theories developed since the early days in its daily practice, promoting environmental and planetary health and thus contributing to achieving the sustainable development goals.
School trajectory of Pedro II High School: an exploratory study on repetition
Authors: Bonamino Alicia , Muylaert Naira , Nierotka Rosileia Lucia
Published: October 2024

Abstract This article investigates how repetition occurs at Colégio Pedro II (CPII), an ensemble of federal public schools considered of excellence, which has sought to democratize access to underprivileged groups through a series of inclusion initiatives. The study uses longitudinal data from 2015 and 2017 Censos Escolares to analyze if a cohort of high schoolers' school trajectories is associated with specific social characteristics. The main results indicate that repetition tends to limit the democratizing and inclusive effects of actions adopted by CPII in the last 30 years, which primarily affect black men with an age-grade gap. The results reaffirm repetition as an excluding practice that broadens social and educational inequalities.
