Authors: Arzate-Camacho Alejandro , López-Patiño Elinor Josefina , Vázquez-Madariaga César , Madariaga-Vázquez Alfonso , Rendón-Aguilar Beatriz
Published: May 2024

Background: Traditional agricultural systems in Mesoamerica are adaptations of ancient farmers to the complex and varied environments. Tezcalera represents one of them.
Questions: How is the environmental context under which the tezcalera develop? Which management practices are followed in tezcalera? How do these management practices affect weeds' richness, composition, and abundance? How do these management practices contribute to the resilience of the agricultural system, the tropical dry forests, and to the maintenance of subsistence resources?
Studied species: Weeds growing in tezcaleras with different management.
Study site and dates: Zumpahuacán, State of México, 2020-2021
Methods: Twenty-four collaborators were interviewed about the environmental, technological, and cultural aspects of tezcalera. We recorded weeds' richness, composition, and abundance in seven plots with different management histories.
Results: Tezcaleras originate from the slash-burn process and follow different paths: tlacolol-milsol-shallow plot, potrero, and recently, Agave crop. We recorded 161 morphospecies from 45 botanical families; 95 % were native to tropical dry forests. Twenty-five species are endemic to the Balsas region, and thirty-four are at risk. Richness and abundance varied between tezcaleras, where tlacolol plots exhibited the highest values. Plant composition was similar; 65 % had intangible or tangible values.
Conclusions: Tezcalera is a biocultural unit and a resilient agroecosystem. Traditional practices remain and positively impact the richness and composition of native weeds. The uncontrolled use of herbicides and the introduction of Agave crop are displacing traditional crops and modifying traditional practices, risking local agrobiodiversity.

Upper limb arterial injury is relatively rare among trauma cases. Among them, the majority is contributed by brachial artery injury. Brachial artery injury is associated with nerve injuries given that its anatomical course, which brings a significant impact to the patient. We reported 2 cases of patients who sustained a deep laceration wound over the right upper limb. Both presented to the Emergency department with active bleeding over the wound, and clinically cold right hand, associated with absent radial and ulnar pulses with profound sensory and motor deficit. Wound exploration and brachial artery repair with reverse saphenous vein interposition graft, followed by structural and nerve repair. This case series highlighted the importance of prompt detection and intervention of brachial artery injury. Any further delay might result missing the golden hour of revascularization for the patients. It also showed the importance of consideration of limb salvage in a patient who was deemed Rutherford III, especially nerve cut was uncertain. In conclusion, prompt intervention of traumatic brachial artery injury and proper intraoperative assessment are mandatory to properly decide if a limb is salvageable or not.
Dealing with the Unexpected: Stercoral Perforation – A Surgical Conundrum
Authors:   Department of General Surgery, Faculty of Medicine, Universiti Kebangsaan Malaysia Medical Centre, Jalan Yaacob Latif, Bandar Tun Razak, 56000 Cheras, Kuala Lumpur, Malaysia
Published: May 2024

Stercoral colon perforation is a rare surgical emergency primarily linked to chronic constipation and advanced age. Diagnosis is challenging and requires established criteria and imaging. Urgent surgery is the modality of choice, typically involving Hartmann's procedure. Mortality rates can be as high as 60%, emphasising the need for early diagnosis and intervention. We presented a case of a 71-year-old bedridden female with a history of stroke, diabetes, and hypertension presenting with abdominal pain, fever and diarrhoea. Initial evaluation indicated dehydration, sepsis, and abdominal tenderness. An urgent imaging revealed a suspected rectal perforation, prompting emergency surgery. Intraoperatively, stercoral perforation due to impacted hard faeces was identified. Despite prompt and intensive treatment, the patient's condition deteriorated, ultimately resulting in her demise. Stercoral colon perforation is a critical condition requiring rapid diagnosis. Symptoms include abdominal distension, tenderness, cramps, fever, and anorectal pain. Healthcare providers should consider the possibility of stercoral perforation in individuals exhibiting these symptoms alongside a background of persistent constipation. Treatment involves peritoneal lavage and surgery. Early recognition is vital for proper management and improved outcomes.

Published: May 2024

Background: The present study was performed to study the role of inflammatory markers viz. C-reactive protein, procalcitonin, serum ferritin and serum lactate dehydrogenase in predicting the mortality and outcome in patients with acute encephalitis syndrome admitted to pediatrics ICU, BRD medical college, Gorakhpur.
Methods: 140 patients/children of the age group ranging from 1 year to 16 years admitted in the acute encephalitis syndrome unit of BRDMC during 1 August 2021 to 31 July 2022 were analyzed with the prospective observational study.
Results: Vaccination status (p<0.001) and socioeconomic status (p=0.020) were associated with mortality outcome in AES patients. Serum procalcitonin levels with cut off value >0.10 mg/dl and serum LDH levels with cut off value of 480u/L have shown a positive association with the mortality in AES patients. (p=0.041 and p=0.038, and strength of association is 0.67 and 0.65, respectively. C-reactive protein with a cut-off value 10 mg/dl and serum ferritin with a cut-off value 140 ng/ml have shown no association with mortality with p values of 0.143 and 0.267, respectively. The Area under the ROC curve is maximum for serum procalcitonin (0.937) with a cut-off value 0.10 ng/dl with 100% sensitivity and 75.8% specificity (confidence interval 95%: 0.894-0.980). The negative predictive value is 100% and PPV is 13.7%. Similarly, the area under the ROC curve for CRP with a cut-off 10mg/dl is 0.900 (confidence interval 95%: 0.841-0.959) with 100% sensitivity of and 64.8%. specificity. Consequently, the negative predictive value is 100 % and the positive predictive value of 11.1%.
Conclusions: For predicting the mortality in AES patients 2 prognostic markers viz. C reactive protein and procalcitonin can prove to be promising prognostic screening tests, and therefore, both the tests are advised consecutively.

Changes in canal diameter and cervical lordosis in patients who underwent en-bloc laminoplasty for the treatment of cervical spinal stenosis
Authors: Meral Mehmet , Koç Rahmi Kemal
Published: May 2024

Objective: Cervical spinal canal-expanding laminoplasty has been recognized as an alternative to cervical laminectomy, especially in multilevel cervical myelopathy due to spinal stenosis. This study aimed to determine the effects of En-block laminoplasty on cervical sagittal balance, cervical spine biomechanics and whether it is sufficient to preserve cervical canal diameter and lordosis and whether it causes additional lordosis or kyphosis in cases of cervical narrow spinal canal.
Methods: Thirty-eight cervical narrow canal patients operated on between 2008 and 2020 were retrospectively evaluated and the results of 24 laminoplasty patients were evaluated. Spinal tomography results for the evaluation of canal diameter changes and X-ray results for cervical sagittal balance evaluation were compared with each other in the early postoperative period and 3 years later. For cervical lordosis assessment, Cobb and C2-C7sagital vertical axis measurements were performed using the PACS system.
Results: Fifteen patients were male and 9 were female. The mean age was 65.55±11.56 years (min-max: 58-84) and the mean follow-up period was three years. Two patients had one level stenosis, 4 had two levels, 7 had three levels, and 11 had four or more levels. Radiculopathy was present in 17 patients (71.8%) and myelopathy in 7 patients (29.1%). There was no statistically significant difference in the frequency of myelopathy/radiculopathy between genders. When all distances were considered, no statistical difference was observed in the early postoperative period (median ten days) and late postoperative period (median 3 years) in terms of canal diameters. No measurement value could be obtained for any level diagnosed as restenosis or requiring reoperation. Loss of lordosis was measured in only one patient. Otherwise, lordosis was preserved in all cases at late conversion.
Conclusions: The results of our study showed that en-block laminoplasty after the cervical narrow spinal canal was sufficient to maintain the cervical canal diameter in the long term with appropriate patient and surgical technique.

Sulawesi is situated at the intersection of three tectonic plates the Indo-Australian, Eurasian, and Philippine plates. The Palu Koro fault is one of the primary causes of seismic activity in the Sulawesi region, making it vulnerable to earthquakes on this Island. As an initial step in disaster mitigation, the information provided is useful in determining the initial signs before the occurrence of an earthquake, it is necessary to identify Ultra Low Frequency (ULF) Signal Anomalies as earthquake precursors. The methods employed are those of power spectrum density (PSD) and single-station transfer function (SSTF). The analysis of anomalies suspected of being precursors to 5 earthquake events revealed that in the February 27, 2023 earthquake, the anomaly appeared twice with a lead time of 17 days. In the February 28, 2023 earthquake, the anomaly appeared twice. In the March 7, 2023 earthquake, the anomaly appeared 3 times with a lead time of 20 days. The March 28, 2023 earthquake had 6 anomalies with a lead time of 24 days. The April 6, 2023 earthquake had 5 anomalies with a lead time of 29 days. anomalies were detected with lead times ranging from 17 to 30 days. The anomaly source azimuth direction was also determined.

Authors: Díaz-Ariza Diana Marcela , Aguilar-Galeano Estíbaliz
Published: May 2024

El objetivo es analizar la agricultura ecológica como parte de la bioeconomía, con énfasis en la triple base. La metodología es cualitativa, utilizando la Investigación Acción Participativa con comunidades de productores agroecológicos en Tenjo y Tibacuy, Cundinamarca. Se encontró que en la dimensión económica, los productores emplean estrategias como el trueque, circuitos cortos y la producción de insumos propios. Sin embargo, la falta de seguimiento de costos y la ausencia de una marca consolidada son debilidades identificadas. En la dimensión ambiental, se destaca la producción de insumos biológicos y prácticas sostenibles, aunque se señala el uso de envases no sostenibles como una debilidad. La falta de seguimiento de la huella ecológica se identifica como un aspecto a mejorar. En la dimensión social, la agroecología fortalece la comunidad a través del trueque, mercados campesinos y generación de empleo. Sin embargo, la falta de certificación, participación limitada en redes y escaso relevo generacional representan desafíos sociales.

Authors: García-Capdevilla Diana Alí , Velásquez-Valencia Alexander , Hernández-Gil Cristian
Published: May 2024

Esta investigación tiene por objetivo analizar los discursos plasmados en los documentos de política pública (PP) y relacionados, sobre turismo de naturaleza (TN) y educación ambiental (EA) para el contexto colombiano. La metodología partió de un análisis documental de tipología cualitativa y un enfoque hermenéutico en función de la comprensión de textos académicos y oficiales en dos ámbitos. Los resultados muestran la concepción del discurso sobre la EA vinculada con otras actividades diferentes al TN, razón por la que no existe una interrelación para formar a los pobladores y fomentar este tipo de prácticas en pro de sensibilizar y crear conciencia ambiental, con el objetivo de identificar las problemáticas y actuar bajo la premisa de proteger la biodiversidad. Se concluye la necesidad de generar actualizaciones normativas que permitan articular los principios de la sostenibilidad con las pericias mercantilistas del turismo, de acuerdo a las demandas de cada región geográfica.

Technological progress has always played a key role in the development of the economy and society throughout human history. Their impact on society is multifaceted and constantly transforming our world. One aspect of social impact is the impact on the sexual division of labour. As a result of these processes, the labour market may undergo significant changes. The impact of technological development on the division of labour between sexes or genders is complex and multifaceted, therefore it can be examined from several aspects. Although technology offers opportunities for gender equality between women and men, the extent and direction of this depends on many factors, including cultural, social and economic circumstances. The present study focuses on an important sector of the economy, healthcare, which is significantly affected by technological development. Among the technological changes taking place in the sector, it examines the emergence of robotic surgery, with a particular focus on its impact on the gender division of labour within the surgical professions.

Published: May 2024

This study aimed to solve the problems of sealing and tearing failure of packer’s rubber cylinders during CO2 downhole injection. Using the simulation software, Comsol, a rubber cylinder model in a supercritical CO2 (SC-CO2) environment was established. The thermal analogy method was used to simulate the CO2 diffusion and rubber cylinder swelling process, thus we analyzed the deformation and stress of the rubber cylinder caused by temperature, pressure and CO2 as swelling agent. Results showed that, in the SC-CO2 environment, under the influence of CO2 diffusion and the consequent swelling, the rubber cylinder body is prone to large deformation, and the maximum shear stress is significantly increased, leading to shear failure of the rubber cylinder. The reduction of the initial seating pressure can alleviate the impact of deformation, whereas the reduction of the maximum contact pressure could cause the rubber cylinder to lose its seal. We also analyzed the change rules between various factors and the maximum contact pressure of the rubber cylinder, which provides a theoretical basis and technical support for improving the sealing performance of the packer’s rubber cylinder in the SC-CO2 environment.

Authors: Lampropoulos Andreas , Paschalis Spyridon , Tsioulou Ourania , Dritsos Stephanos
Published: May 2024

The strengthening of existing columns using additional Reinforced Concrete (RC) jackets is one of the most popular techniques for the enhancement of column’s stiffness, load bearing capacity and ductility. Important parameters affecting the effectiveness of this method are the strength of the additional concrete, the concrete shrinkage and the connection between the old and the new con-crete. In this study the application of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) jackets for the structural upgrade of RC columns has been examined. Extensive numerical study has been conducted to evaluate the effect of parameters such as the thickness of the jacket, the concrete shrinkage and the addition of steel bars and comparisons have been made with conventional RC jackets. The results of this study indicate that the use of UHPFRC can considerably im-prove the strength and the stiffness of existing RC columns. The combination of UHPFRC and steel bars in the jacket leads to the most effective strengthening technique as a significant enhancement of the stiffness and the ultimate load capacity has been achieved.

Dominance hierarchy limits resilience in the endangered queenless ant Dinoponera lucida

Division of labour is an important factor of social insect ecological success. However, species differ widely in the specific mechanisms associated with division of labour. Often, social groups have to cope with severe perturbations and resume normal functioning as quickly as possible. How well they do so depends on the behavioural mechanisms involved and on species life-history traits. Here, we studied the division of labour in D. lucida, a threatened species of native Brazilian queenless ants with small colony sizes, to assess whether colonies facing a drastic perturbation of the established task allocation are resilient, and through which potential mechanisms. We first separated the colonies into two sub-colonies, one with the foragers and the other with the nurses. As this is an important modification of colony structure, we expected workers to respond quickly by switching tasks. Our experiment showed that, contrary to our hypotheses, workers showed little plasticity in switching tasks, and colonies did show very limited resilience. Foragers, when isolated from nurses, show a certain plasticity in their behavioural repertoire, performing both tasks (foraging and nursing). However, groups of nurses facing the absence of foragers kept almost exclusively to nursing tasks. Only a few performed episodic outside activities. When workers were returned to their original colonies, foragers switched back to foraging. However, the effect of the manipulation could still be observed 20 days after reintroduction, with workers showing lower general activity, ingesting larvae and reproductive workers losing their dominance. Considering our current knowledge about the regulation of both division of labour and reproductive hierarchies in Dinoponera and other ponerine ants, we propose that this lack of resilience is due to the reproductive conflict between nurses, which delays behavioural maturation and motivation to engage in outside tasks. The existence of individual strategies thus imposes severe costs on group functioning. This could be an additional issue when considering the conservation of this endangered species.

Male breast cancer (MBC) is a relatively rare and inadequately researched disease, and its cellular and molecular traits remain obscure. In this study, we conducted single-cell sequencing (N=20) and spatial transcriptomics (N=14) on 34 fresh tissue samples from 27 MBC patients. We identified six major cancer cell subtypes that are associated with the development and progression of MBC. Specifically, cancer cells exhibiting neuroendocrine-like properties facilitate immune evasion, tumor angiogenesis, epithelial-to-mesenchymal transition, cell proliferation, tumor invasion, and metastasis. They do so by secreting neuro-related factors and engaging in regulating neuro-related signaling pathways, synergistically interacting with T cells, macrophages, and fibroblasts within the tumor microenvironment. Additionally, we found that mutations or copy number variations amplifications of the UTY gene on the Y chromosome and/or its high transcript expression are closely associated with adverse clinical outcomes in male cancer patients, including MBC patients. In conclusion, our study provides important data support for a deeper understanding of the molecular characteristics and tumor microenvironment of MBC, and offers important clues for developing improved therapeutic strategies to improve the prognosis of MBC patients.

Introduction: Robotic assistance for total hip arthroplasty (THA) has been demonstrated to improve accuracy of acetabular cup placement relative to manual, unassisted technique. The purpose of this investigation was to compare the accuracy and precision between a fluoroscopy-based robotic total hip arthroplasty platform (FL-RTHA) and a computerized tomography-based (CT-RTHA) platform.
Methods: The study included 98 consecutive FL-RTHA and 159 CT-RTHA procedures performed via direct anterior approach (DAA). All cases were performed for a pre-operative diagnosis of osteoarthritis, avascular necrosis, or rheumatoid arthritis. Primary outcome variables included cup implantation accuracy and precision (variance). Implantation accuracy was calculated as the absolute value of the difference between pre-operative target cup angles (inclination and anteversion) and the same post-operative angles. Percentage placement in the Lewinnek safe zone was also measured for both cohorts.
Results: The FL-RTHA and CT-RTHA cohorts demonstrated a 1.2° difference in absolute values for cup inclination accuracy (4.6° ± 3.6 vs. 3.4 ± 2.7; p=0.005), and no difference in absolute values for cup anteversion accuracy (4.7° ± 4.1 vs. 4.6 ± 3.4; p=0.991). Cohorts demonstrated similar precision for cup inclination and anteversion placement parameters, as well as equivalent Lewinnek safe zone placement.
Conclusions: The use of a fluoroscopy-based robotic assistance platform for primary DAA THA resulted in similar accuracy and precision of acetabular cup placement when compared to a CT-based robotic assistance system.

Published: May 2024

The field surveys were conducted at the following three different water heads, i.e., Sulamnki, Islam, and Panjnad, of the Sutlej River from June 2021 to November 2021, and this is the first effort to estimate the diversity and assess the current threats to the mammalian fauna of the Sutlej River. During the surveys of the research areas, a total of 266 individuals belonging to four orders, seven families, and 12 different species were observed. According to the results, greatest number of individuals of the Rodentia order and the Muridae family, and lowest number of individuals in the Lagomorpha order and the Leporidae family. According to the indices, the Panjnad waterhead showed the greatest diersty and evenness, followed by those of Sulamanki and Islam, with H = 2.453746 and E = 1.065648, H = 2.200177 and E = 0.955525, and H = 2.136116 and E = 0.927703, respectively. The richness of mammals was the same at all three localities (R = 1.61189). Throughout the investigation, some threats, such as pollution, destruction of habitat and the Humen–Wildlif conflict, were observed to drastically affect mammalian diversity.
