Authors: Varghese Chris , Daker Charlotte , Lim Alexandria , Sebaratnam Gabrielle , Xu William , Kean Bernard , Cederwall Chris
Published: August 2023

Introduction

Chronic gastroduodenal symptoms are frequently overlapping within existing diagnostic paradigms and current diagnostic tests are insensitive to underlying pathophysiologies. Gastric Alimetry has emerged as a new diagnostic test of gastric neuromuscular function with time-of-test symptom profiling. This study aimed to assess the impact to diagnosis and healthcare utilization following the introduction of Gastric Alimetry into clinical care.

Methods

Consecutive data from two tertiary centers with chronic gastroduodenal symptoms (Rome-IV defined, or motility disorder), having integrated care and Gastric Alimetry testing were evaluated. Changes in diagnoses, interventions, and management were quantified. Pre- and post-test health care utilization was reported. A preliminary management framework was established through experiential learning.

Results

50 participants (45 women; median age 30; 19 with gastroparesis, 25 with CNVS, and 7 with FD) underwent Gastric Alimetry testing. One-third of patients had a spectral abnormality (18% dysrhythmic / low-amplitude). Of the remainder, 9 had symptoms correlating to gastric amplitude, while 19 had symptoms unrelated to gastric activity. Gastric Alimetry aided management decisions in 84%, including changes in invasive nutritional support in 9/50 cases (18%; predominantly de-escalation). Health care utilization was significantly lower post-Gastric Alimetry testing (mean $39,724, SD ± 63,566 vs $19,937, SD ± 35,895, p=0.037).

Conclusion

Gastric Alimetry aided diagnosis and management of patients with chronic gastroduodenal symptoms by enabling phenotype-informed care. The high majority of tests aided management decisions, which was associated with reduced healthcare utilization.

Significance of sTREM-1 and sST2 combined diagnosis for sepsis detection and prognosis prediction
Authors: Wei Yongjun , Xiao Ping , Wu Benjuan , Chen Fuxi , Shi Xiaofeng
Published: August 2023

The diagnosis of sepsis still lacks a practical and reliable gold standard. The purpose of this study was to confirm the effect of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) combined with soluble suppression of tumorigenicity 2 (sST2) in the diagnosis of sepsis through the correlation between sTREM-1, sST2, and sequential organ failure assessment (SOFA) scores. Baseline data of 91 patients with sepsis in the intensive care unit were collected, sTREM-1 and sST2 were detected, and the correlation between markers and SOFA score was analyzed. Besides, the prognostic value of baseline and postadmission indicators for sepsis was analyzed with death as the outcome. The results showed that the expressions of sST2 and sTREM-1 in death group and survival group were higher than those in the survival group (p < 0.05). Correlation analysis showed that sST2, sTREM-1, and the joint diagnosis model had a high correlation with SOFA score (p < 0.05), but poor correlation with Acute Physiology and Chronic Health Evaluation Ⅱ score (p > 0.05). Among them, joint diagnosis model has the highest correlation. Receiver operating characteristic curve analysis showed that combined diagnosis had higher area under curve values. sTREM-1/sST2 can be better used in the diagnosis of sepsis than the single biomarker detection, and the combination of the above two biomarkers has potential application value in the detection and prognosis prediction of sepsis.
From Zeno ad infinitum: Iterative Reasonings in Early Greek Philosophy
Authors: Seban Pierrot
Published: August 2023

This paper considers some aspects of the early conception and use of the infinite in ancient Greece, in the spirit of recent results in the history of ancient mathematics. It follows aspects of the practice of reasoning ad infinitum from the extant corpus of and about Zeno of Elea up to early Hellenistic examples in Aristotle and Euclid. Starting with the idea of ‘reasoning from indefinite iteration’, based on the metalogical recognition of the unachievability of an inference process, it identifies several different classes of more or less sophisticated arguments that make use of this idea, and examines the logical devices and notions required for their acceptance in the philosophical practice. Those include ‘Infinite regress’ properly speaking, where Non-Contradiction is used in the formation of indirect infinitary arguments.

The oral cavity is home to diverse microbial content, collectively called the oral microbiome. The latest technological advancements have unraveled the intricacies of the oral microbiome. It can be of great importance for oral health care givers to know the fundamentals and latest developments in the field of the oral microbiome, as oral dysbiosis is associated with many common diseases frequently seen and managed by them. These diseases include dental caries, periodontitis, mucosal diseases (such as oral leukoplakia, oral lichen planus, and systemic lupus erythematosus), oral cancers, and even co-infections related to the current COVID-19 pandemic. The emergence of new genomic and molecular biology methodologies has been pivotal for understanding the role of the human microbiome in health and disease. The current review compiles oral microbiome in health and disease with a multidisciplinary dental approach. The insight into the oral microbiome, which is provided dental specialty wise in the current article will initiate and guide researchers of various disciplines in developing microbiome-based therapeutic or prophylactic management strategies, managing public health challenges by microbiome-based boarder interventions and divert resources for preserving and achieving a balanced oral microbiome.
The Influence of Prestimulus 1/f-Like versus Alpha-Band Activity on Subjective Awareness of Auditory and Visual Stimuli
Authors: Cunningham Emily , Zimnicki Clementine , Beck Diane M.
Published: August 2023

Alpha rhythmic activity is often suggested to exert an inhibitory influence on information processing. However, relatively little is known about how reported alpha-related effects are influenced by a potential confounding element of the neural signal, power-law scaling. In the current study, we systematically examine the effect of accounting for 1/f activity on the relation between prestimulus alpha power and human behavior during both auditory and visual detection (N= 27; 19 female, 6 male, 2 nonbinary). The results suggest that, at least in the scalp-recorded EEG signal, the difference in alpha power often reported before visual hits versus misses is probably best thought of as a combination of narrowband alpha and broadband shifts. That is, changes in broadband parameters (exponent and offset of 1/f-like activity) also appear to be strong predictors of the subsequent awareness of visual stimuli. Neither changes in posterior alpha power nor changes in 1/f-like activity reliably predicted detection of auditory stimuli. These results appear consistent with suggestions that broadband changes in the scalp-recorded EEG signal may account for a portion of prior results linking alpha band dynamics to visuospatial attention and behavior, and suggest that systematic re-examination of existing data may be warranted.

Significance StatementFluctuations in alpha band (∼8–12 Hz) activity systematically follow the allocation of attention across space and sensory modality. Increases in alpha amplitude, which often precede failures to report awareness of threshold visual stimuli, are suggested to exert an inhibitory influence on information processing. However, fluctuations in alpha activity are often confounded with changes in the broadband 1/f-like pattern of the neural signal. When both factors are considered, we find that changes in broadband activity are as effective as narrowband alpha activity as predictors of subsequent visual detection. These results are consistent with emerging understanding of the potential functional importance of broadband changes in the neural signal and may have significant consequences for our understanding of alpha rhythmic activity.

Authors: Montes Mata Giovanni Marlon , Monroy Ortiz Rafael , Flores Reséndiz Rodrigo , Monroy Ortiz Columba
Published: August 2023

La subcuenca del río Apatlaco es considerada una de las más contaminadas en México y los 11 municipios que la integran tienen una demanda de alcance federal desde 2016, promovida por “habitantes de Morelos”, la cual exige detectar y frenar todo tipo de descargas irregulares de aguas residuales sin tratamiento hacia los cuerpos de agua superficial. Por tanto, el objetivo es analizar la incidencia de la lógica de contaminación con aguas residuales sin tratamiento en la subcuenca del río Apatlaco, Morelos, México con el riesgo de la seguridad alimentaria por efecto de la irrigación de sus áreas agrícolas. Se analizaron las condiciones de contaminación por efluentes con base en una unidad territorial (Cuernavaca) incluyendo identificación y cálculo de los puntos de descarga distribuidos por usos de suelo. Con base en la unidad territorial, se calculó el agua residual generada por los 11 municipios de la subcuenca tomando en cuenta el gasto per cápita de la muestra, habitantes por municipios, el porcentaje respecto la población total estatal y aquel localizado dentro de la subcuenca. Por último, se identificó la superficie agrícola y las líneas de corriente del Apatlaco para determinar la susceptibilidad del uso de aguas negras en la producción de alimentos.

Authors: Bülbül Zübeyde , Üner Birol
Published: August 2023

Tetra Pak® paper and PE (polyethylene) wastes were evaluated to obtain a new composite material with awareness of environmental responsibility. Fillers and coupling agents were used for this joining process. Calcite (CaCO3), boric acid (H3BO3), SPT (Sodium Perborate Tetrahydrate / NaBO3.4H2O), titanate, MAPE (maleic anhydride grafted polyethylene, and vinyltriethoxysilane (C8H18O) composites were produced in 30 × 30 cm plates. A total of 30 samples were prepared as 5 mg flour for thermogravimetric analysis (TGA). Samples were observed in a thermal analyzer at 10, 15, or 20 °C/min heating rate in nitrogen atmosphere. Graphs were obtained as a result of TGA, and the activation energies were calculated using these graphs. The activation energy was calculated using the Flynn-Wall-Ozawa method. The determined activation energies of the composites were close to each other for each temperature group. In the samples using calcite and vinyltriethoxysilane, relatively higher activation energies were observed in comparison to the samples with boric acid and MAPE.

Authors: Pirovski N. , Ivanova I. , Hamza S.
Published: August 2023

The accumulated amount of information about human morphology is enormous and this leads to a suitable environment for a new qualitative leap in the understanding of the human body. Material and Methods: Scientific publications available online. The methodology is: heuristic formation of the goal, systematic thinking, holistic approach, and comparison between the up-to-date embryology facts with the modern theories in physics and the traditional holistic philosophies of China.
Aim: The purpose of this report is to validate STHB from an embryological point of view. Results: The embryonic period provides clear evidence for the spiral theory of the human body, demonstrating the center, its boundary, the equal importance of negative and positive structures, the primordial scale and the transition to different sub-scales, its short duration, and the clear transition to the next period of life. Conclusion: Most axioms of the STHB could be validated by human embryo development. As a disadvantage, one can consider the weak anthropological demonstration of the typical human characteristics that distinguish him from the animal world.
EFFECT OF PLANT GROWTH REGULATORS IN THE PROPAGATION OF SEEDLING EXPLANT CAPSICUM ANNUUM L. VAR. ANNUUM
Authors: Mandal M.
Published: August 2023

This is a very initial phase of work where the object was to find out a very simple and effective process of in-vitro plant generation of Capsicum annuum L. var. annuum. For the regeneration of plants, various explants have been used including different parts of seedlings, axillary buds, and apical buds. This study revealed that basal media containing 2, 4 D (1.5mg/l.) and kinetin (0.5 mg/l.) were acting as callus-forming media. MS basal media with NAA (1.0 mg/l.) and BAP (0.5 mg/l.) was acting as callus with some roots growing media. A small quantity of kinetin along not shows any significant changes. It has been found that axillary buds and apical buds were increased in length into the kinetin (1.5mg/l.) containing media. Later axillary bud and apical buds were transferred into the MS basal media containing NAA (1.0 mg/l.) and BAP (0.5 mg/l.), which act as callus with root forming media, and help to regenerate healthy new plantlets in a short period. The survival rate of these plants is 80%. Sugar and protein estimation was done. Sugar and protein content was much higher in in-vitro plants as compared to callus.
The Impact of Unemployment on the Dynamics of New Companies Entry
Authors:   Lomonosov Moscow State University, Zazdravnykh Alexey
Published: August 2023

The state of labor markets and the unemployment rate are a factor influencing entrepreneurial activity and the processes of creating new firms. The article is devoted to the study of this issue on the example of the Russian economic model. The purpose of the article is to eliminate a gap in the Russian scientific literature associated with the lack of research on the impact of the unemployment factor on the entry of new firms. Using the example of statistical data of the Russian federal districts in the period 2005–2021, it was found that the entry parameters of new companies were characterized by a declining trend, with a sharp drop in times of crises (2009 and 2020). However, the multidirectional dynamics at the stages of recovery growth and local recessions were revealed. Modeling in paired regressions showed the nonlinear nature of the impact of unemployment on the dynamics of the entry of new firms. The results of evaluating the model with random effects showed the negative impact of unemployment on the entry of new firms on average for the entire analyzed period. In addition to the unemployment rate, significant factors in the dynamics of companies entry were the growth rates of real GRP, real monetary incomes of the population and the dynamics of the total number of companies in previous periods. The current economic situation requires increased attention to the situation in the regional labor markets and stimulating the business activity of Russian companies.

The article is devoted to the results of testing the methodology for assessing the management of the socio-economic development of the region on the example of the Volgograd region. The author’s methodology includes three main blocks and an additional one. The assessment of the overall level of socio-economic development of the Volgograd region was carried out on the basis of 67 indicators for eight regional subsystems considered as factors of regional development. The results of the current assessment were compared with the past conditions of the region as well as with the average indicators for the Southern Federal District (SFD), summarized in the assessment of its synthetic region. The evaluation results are presented in tabular, graphical and matrix forms, which significantly increases the analyticity of the probed technique. As a result of approbation of the methodology for calculations and assessments of the Volgograd region socio-economic development management, it was empirically revealed that: there is the Matthew effect; the least weight in the formation of the development level of Volgograd region is contributed by environmental and natural resource factors, the greatest – social, financial and infrastructure factors; socio-economic development of the Volgograd region is most sensitive to changes in the social, innovative and infrastructural factors-subsystems; factors limiting socio-economic development for the Volgograd region and the synthetic region of the SFD are the environmental on the lower boundary and social factors-subsystems – on the upper one. Further directions of development and application of the results of the approbation of the considered technique made by the authors are determined.

Authors:   Kazan Federal University, Seliverstova Nataliya
Published: August 2023

This article describes the results of a scientific literature study and practical examples of the production of data processing products that are generated by enterprises of different industries based on international experience. The prerequisites for the development of data-based management approaches are described: firstly, the evolution of architectural approaches to working with data from centralized repositories to decentralized data sets (domains, subject areas) over the past two decades; secondly, the dissatisfaction of companies with the existing data processing mechanisms; and thirdly, the importance of data for internal and external consumers (employees and customers) to make decisions and/or create additional value added (in this step, only in a theoretical view, without quantitative measurement). The role of network relations between business structures in the process of using data as a valuable asset and in the field of digital transformation in general is described. As a result of observation, the concept of the value of products based on data for external and internal consumers (customers and employees) is formulated. It is shown that a higher demand for prepared data sets is observed from the departments involved in the main business processes compared with the departments that belong to the auxiliary or service departments. This article seems to be of an overview nature, and it is intended to highlight the existing private situations in the field of data processing in firms, corporations, and other business structures.
ARCHITECTURAL DESIGN STRATEGIES IN 20TH AND 21TH CENTURY ARCHITECTURAL DISCOURSES
Authors: ÖZTÜRK Özge , ARIDAĞ Levent
Published: August 2023

Aim: Approaches that consider the concept of space independent from the subject and consider it as a static phenomenon in architectural practice leave their place to approaches which consider the subject together with the senses and experiences and call the place a dynamic concept. The aim of the study is to explain the transformation between these two basic approaches and to reveal the effects of new approaches on the design process. Method: In this study, the milestones in the architectural design environment are discussed through manifestos of the leading architects and residential buildings. These structures, design, conceptualizing expressions, layers, layers of the mapping strategy, geometric structure and production technologies to examine, compare and evaluate the method of the research. Results: The diagrams that summarize the situations in which they relate to each other in a comprehensible way and make decisions based on them are transformed into cartographic diagrams. With the combination of these diagrams and the understanding of cartography which includes more information and layers, it is possible to produce more sensitive and complex designs in today's architectural environment. Conclusion: The open-ended mapping strategy can enable architects to explore and control the complex structure of design. With this method, which mediates the emergence of new connections, forms of intricate relations and a way to produce new sensibilities that are not seen in architecture can be found.
THE EXPERIMENTAL AND NUMERICAL INVESTIGATION OF THE THERMAL BEHAVIORS OF A JACKETED HEAT EXCHANGER WITH A STIRRER
Authors: BAYRAM Halil , SEVİLGEN Gökhan , CESUR Mert
Published: August 2023

In this study, the thermal performance of a jacketed heat exchanger with a stirrer was experimentally and numerically investigated under different jacket side water inlet temperature and flow rate conditions. In the numerical study, a three-dimensional computational fluid dynamics (CFD)model of the heat exchanger was generated and the analyzes were performed with the ANSYS-Fluent software package. In addition, a stirrer was added to both the experimental and the numerical study to obtain the effects of the stirrer on the temperature and velocity values of the water in the tank. It was seen that the results of the analyzes performed under similar conditions to the experimental study were in good agreement with the experimental study. It was concluded that the effect of the flow rate decreases with increasing inlet temperature. When the stirrer was activated and the flow rate was increased from 0.5 to 2.5 l/min in 30, 40, and 50°C inlet temperature conditions, the time to reach the target temperature inside the tank decreased from approximately 1600 to 900, from 2500 to 1350, and from 4900 to 1400, respectively. In general, it was observed that the effect of the stirrer increased with increasing inlet temperature in all flow rate conditions.

Published: August 2023

Objectives: Encephalitis and meningitis can have serious and potentially life-threatening consequences. This study aims to investigate whether the effects of systemic immune inflammation index (SII) and neutrophil/lymphocyte (N/L) ratio on differential diagnosis, severity, and clinical outcomes are superior to each other in patients diagnosed with encephalitis and meningitis in the emergency department.
Methods: Patients aged 18 years and older who presented to the adult emergency department of the hospital and were diagnosed with meningitis or encephalitis between January and December 2022 were included in the study. Patients under 18 and those with missing data in their files were excluded from the study. N/L ratio, SII values, and other associated parameters were compared between the group with mortality and the group who survived both diseases.
Results: There were significant differences in neutrophil, lymphocyte, N/L ratio, SII, and C-reactive protein (CRP) values between meningitis and encephalitis patients. N/L ratio and SII values were significantly lower in encephalitis patients than in meningitis patients. There was no significant difference in any of the parameters between surviving and deceased patients.
Conclusions: Simple calculable ratios such as SII and N/L ratio can be a supportive parameter in the differential diagnosis of the disease. However, it has been observed that using these indices is not a useful tool in determining the severity and prognosis of patients with encephalitis and meningitis.
Elementary School Mathematics Teacher Candidates' Competence to Design Model-Eliciting Activities, Beliefs for Problem Solving, Self-Efficacy Beliefs for Problem Posing and the Relationship Between Them
Authors: BARAN BULUT Demet
Published: August 2023

This study aimed to determine the change and the relationship between elementary school mathematics teacher candidates' competence to design model-eliciting activities, their beliefs towards problem-solving, and their self-efficacy beliefs towards problem posing according to gender and overall academic grade point average (GPA). Modeling activities designed by 64 elementary school mathematics teacher candidates in Turkey were evaluated by means of a grading key created in the context of "compliance with MEA design principles". In addition, a scale consisting of 24 items was applied to determine the beliefs of the teacher candidates towards problem-solving, and a 26-imoetem scale was applied to determine their self-efficacy beliefs towards problem-posing, and the responses were analyzed by quantitative methods (one-way multiple variance analysis, correlation analysis, multiple regression test). The findings reveal that elementary school mathematics teacher candidates' proficiency in designing model-eliciting activities is generally at a high level, while their belief in problem-solving and self-efficacy beliefs in problem posing is generally at a moderate level. Based on the studies that concluded that modeling competencies develop as they work on modeling problems and that the experience of mathematical modeling affects their mathematical modeling competencies, it was concluded that modeling problems were used to solve mathematical problems and teach these solutions in the mathematical modeling course they took. It was determined that the linear combinations of teacher candidates' proficiency in designing model-eliciting activities, beliefs in problem-solving, and self-efficacy beliefs in problem-posing did not show a significant difference. The fact that pre-service teachers' beliefs about problem solving and posing are not related to their MEA design competencies is thought to be due to their previous routine mathematical problem solving experiences being more dominant. On the other hand, since the mathematical modeling process is basically considered as a problem-solving process, it was expected that these beliefs of pre-service teachers would be related to MEA design proficiency. It is important to conduct qualitative research with teacher candidates in order to examine this situation in more detail and to reveal the underlying causes.

Published: August 2023

Numerous studies have shown that quinolones residues in the foods exceeding the MRL is harmful to the human health. There are some limitations in the existing methods for the residues, so we developed a new limit test method (TLC-SERS) to rapidly determine following residues: enrofloxacin(A), ciprofloxacin (B), ofloxacin(C), fleroxacin(D), sparfloxacin(E), enoxacin(F), gatifloxacin(G) and nadifloxacin(H). The residues can be preliminarily separated by TLC. Labeling the tested compounds’ position on the thin layer plate by their relative Rf under 254nm ultraviolet, and an appropriate amount of nanometer silver solution should be added to the position. The silver on the plate should be irradiated with 532nm laser to obtain SERS of the compounds. The results showed a significant differences of the 8 quinolones’ SERS; the LOD of the H, A, D, E, C, G, F and B were orderly 9.0, 12.6, 8.0, 19.0, 8.0, 8.4, 9.0 and 12.6 ng/mL, and the RSD≤4.9% for SERS of each quinolones.The limit test results of the 20 samples was consistent with that determined by the UPLC–MS/MS. The above results indicate that the TLC-SERS is specific, sensitive, stable, and accurate, providing a new reference for the rapid limit test of harmful residues in foods.
Influence of the Nursing Manager’s Vocation for Leadership and Its Impact on the Hospital Work Environment in Mexico
Authors: Yañez- Lozano Angeles , Lillo-Crespo Manuel
Published: August 2023

Background: The presence of a leadership role in the nursing manager appears to be closely related to a positive and productive work environment within health settings. In some contexts, such as Mexico, the profile of the nursing manager has not been formally defined, and, sometimes those who occupy these positions do not always have sufficient training, and therefore this vocation, which is related to the social image of the nursing profession. This study aims to understand the influence of the vocation for leadership that the nursing manager has and how it can influence the work environment, through the analysis of experiences lived by health professionals with a management profile of different health environments; Methods: Qualitative study of an approximation to grounded theory using Corbin & Strauss as reference, using semi-structured individual interviews as a technique, and with the participation of 10 Mexican nursing managers from second-level care hospitals; Results: The meaning of the vocation for the interviewed managers is based in the first instance on the love of the profession and the vocation to be a nurse, then on the development of leadership for decision-making in practice and is fed back with the positive effects that it generates in the work environment, helping them to better organize human resources and professional activities, and strengthening themselves with specific training on the subject and the experience acquired. ; Conclusions: An understanding model is provided about the phenomenon where two central categories were identified, the first central category is the "Management vocation and natural nursing leadership" which is the basis; The second central category is the "Explanation and influence of the managerial vocation, natural leadership and work environment in nursing". Two connection categories were also created; the connection category one "Motives, meaning, and practical vocation of managerial nursing" and the connection category two "Description of the managerial vocation, natural leadership, and work environment", said connection categories emanate from the central category one, to connect with the central category two, which contains the interaction of the managerial vocation, natural leadership, and work environment in nursing.
Integrated Learning Activity Prediction Model of BHO-AdaBoosting Anti-Breast Cancer ERα Inhibitor Based on Improved Random Forest
Authors: Du Yanxuan , Xu Zhengjie , Huang Jiaxin , Lyu Chengxuan , Lu Cunhao , Chen Jian
Published: August 2023

Breast cancer is the most common malignancy in women worldwide. The pathogenesis of this disease is closely related to the estrogen receptor alpha subtype (ERα). Therefore, it is of great importance to develop effective inhibitors of ERα activity for the treatment of breast cancer. In this paper, we propose a novel ensemble machine learning model for quantitative structure-activity relationship of anti-breast cancer drugs, which can effectively predict drug activity in small samples with multiple characteristic variables. To avoid the problem of over-fitting caused by low-correlation independent variables, the scoring mechanism of random forest was improved by incorporating three relevance indicators, including the maximum mutual information number, Pearson correlation coefficient and distance correlation coefficient, and 20 optimal molecular descriptors were selected. The Bayesian hyperparameter optimization method was used to optimize the parameters of multiple linear regression (MLR), support vector regression (SVR), and extreme gradient boosting (XGBoost), respectively. The AdaBoost strong learner was constructed by combining the weak learner with the weighted linear addition method. The results show that the proposed ensemble learning model has the best prediction performance compared to the three basic learner models and the CNN-LSTM combination prediction model. The root mean square error was reduced by 7.60%-26.51%. The mean relative error was reduced by 6.46%-30.92%. Goodness of fit increased by 9.57%-36.94%. Finally, the biological activities of 50 candidate compounds for ERα inhibitors were predicted, and it was found that 4-[2-benzyl-1-[4-(2-pyrrolidin-1-ylethoxy)phenyl]but-1-enyl]phenol had an excellent biological activity value pIC50, which had the potential to be an ERα inhibitor. The model proposed in this paper has good prediction accuracy, which can provide an effective reference for the discovery and development of anti-breast cancer drugs.
Reconstruction of Prehension in C7-T1 Brachial Plexus Injury with Nerve and Tendon Transfers
Authors: Chim Harvey
Published: August 2023

Case:

Reconstruction of function in C7-T1 lower brachial plexus injury requires restoration of finger flexion and extension with nerve or tendon transfers. A 22-year-old man was involved in an all-terrain vehicle rollover accident. First-stage nerve transfers included extensor carpi radialis brevis to the anterior interosseous nerve and supinator to the posterior interosseous nerve. After second-stage (15 months later) side-to-side flexor digitorum profundus and Camitz abductorplasty, he was able to achieve tripod pinch and power grip.

Conclusion:

A combined approach with nerve transfers followed by tendon transfers allows restoration of prehension in lower BPI while preserving the brachialis as a backup donor.

Published: August 2023

Case:

A 31-year-old man with a history of giant cell tumor of bone (GCTB) in the distal radius presents to clinic 9 years after en bloc distal radius resection. He was found to have a new soft tissue mass consistent with GCTB and new pulmonary metastases. Ultimately, he underwent excision of his soft tissue recurrence and partial lobectomy for his lung metastases.

Conclusion:

This case highlights the importance of having a high level of suspicion for local recurrence or metastasis, even years after wide resection and negative margins.
Systematic Literature Review and Meta-Analysis on Miserable Malalignment Syndrome
Authors: Atallah Sarah , Hanna Maged
Published: August 2023

Background:

Miserable malalignment syndrome (MMS) is a rare condition that entails increased femoral anteversion and increased external tibial torsion, as well as the presentation of one, some, or all the following: squinting patella, patella alta, patellar instability, an increased Q angle, genus valgus (knock knees) or genus varum (bow leggedness), genus recurvatum, feet pronation, or pes planus.

Methods:

The Sample, Phenomenon of Interest, Design, Evaluation, Research type search strategy was used to retrieve eligible studies from databases fitting the established inclusion criteria.

Results:

All studies agreed that nonoperative treatment is ineffective in improving MMS. Surgical treatment is effective, although it involves osteotomies at 2 levels per limb.

Conclusions:

Double-level osteotomies were effective in all studies, vastly improving range of motion, chronic knee pain, chronic hip pain, and other factors. Surgical treatment of this condition should only be reserved for severe cases because complications are possible.

Level of Evidence:

Most articles used were part of a case series, indicating this review article is based on level 4 evidence.

Published: August 2023

Objetivos: Evaluar la actividad inductora de apoptosis in vitro de la fracción clorofórmica de Piper aduncum en líneas celulares del cáncer gástrico. Materiales y métodos: La inducción de la apoptosis se evaluó en las líneas celulares: AGS y KATO III, las cuales fueron incubadas con 39,23 µg/ml y 87,49 µg/ml de concentración inhibitoria media (IC50) de la fracción clorofórmica de Piper aduncum respectivamente. El ensayo de expresión génica se realizó por PCR en tiempo real, evaluando la expresión de los genes APAF1, NOL3, BAX, BCL2L1, XIAP y TBP como gen constitutivo. Resultados: La fracción clorofórmica de Piper aduncum mostró inducción de la apoptosis en la línea celular AGS a través de la inhibición de la expresión de los genes anti apoptóticos XIAP y BCL2L1, sin embargo, no mostró diferencia significativa en NOL3 ni en los genes proapoptóticos APAF1 y BAX. En las línea celular KATO III no se observó diferencia significativa tanto en los genes pro apoptóticos como anti apoptóticos. Conclusiones: La concentración inhibitoria media (IC50) de la fracción clorofórmica del Piper aduncum disminuyó la expresión de los genes anti apoptóticos XIAP y BCL2L1 en la línea celular AGS del cáncer gástrico, favoreciendo la inducción de la apoptosis.

Authors:   , Fernandez Perez Merari Rayza
Published: August 2023

Introducción La inseguridad alimentaria afecta a 267 millones de personas en el mundo. Los hogares que tienen un miembro con discapacidad podrían tener mayor riesgo de inseguridad alimentaria. Objetivos Evaluar la asociación entre la condición de discapacidad de los jefes de familia y la inseguridad alimentaria en los hogares de pobladores de Colombia, durante el 2017. Metodología Se realizó un análisis secundario de los datos de la Encuesta Nacional de Calidad de Vida (ECV) 2017 de Colombia. La variable independiente fue la condición de discapacidad medida con las preguntas del grupo de Washington y la variable dependiente fue la inseguridad alimentaria determinada con la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA). Se incluyeron posibles variables de confusión de tipo sociodemográficas y relacionadas con la inseguridad alimentaria. Para demostrar la asociación se realizó una regresión logística ordinal y se estimaron odds ratio (OR) con sus intervalos de confianza al 95% (IC95%). En todos los cálculos se tuvo en consideración el muestreo complejo de la ECV 2017. Resultados Se incluyeron los datos de 8488 jefes de familia. El 9,2% admitió que presentaba alguna discapacidad y el 41,8% indicó que su hogar estaba en riesgo de inseguridad alimentaria. Los hogares, cuyo jefe de familia tenían discapacidad presentaron 30% más probabilidad de mayor inseguridad alimentaria en comparación con los hogares cuyos jefes de familia no tenían discapacidad (RP=1,30 IC95%: 1,07–1,59), ajustado por múltiples variables. Conclusiones En Colombia, durante el 2017, la discapacidad de los jefes de familia aumenta la probabilidad de mayor inseguridad alimentaria en los miembros de su hogar, solo si son hombres y tienen más de 60 años. En necesario la creación de programas de asistencia nutricional enfocada en las poblaciones vulnerables como las personas con discapacidad.

La presencia de estudiantes diversos en las aulas en el nivel educativo superior cada vez se viene acrecentando, ante esto, surge la necesidad de atender a diferentes colectivos y responder a sus necesidades educativas, culturales, lingüísticas, sociodemográficas, entre otros. Bajo este contexto, la formación a nivel pedagógico de los docentes en el nivel superior es un factor esencial para desarrollar una atención inclusiva en las instituciones superiores. Se tuvo por objetivo establecer la relación entre la formación pedagógica y la educación inclusiva en docentes de dos institutos en la ciudad de Cerro de Pasco, y, además, determinar la diferencia existente en el desarrollo de la educación inclusiva en docentes de dos institutos de nivel superior con y sin formación pedagógica en la ciudad de Cerro de Pasco. El método utilizado en la presente investigación fue de enfoque cuantitativo de tipo básica, de nivel descriptivo – comparativo y correlacional simple en el que participaron 71 docentes con y sin formación pedagógica. El análisis de datos se llevó a cabo mediante estadística descriptiva, análisis estadístico no paramétrico utilizando el test U de Mann Whitney y el Rho de Spearman. Entre los hallazgos más importantes, la presente investigación revela que la formación pedagógica y la educación inclusiva presentan correlación positiva directa (rho=0782). Sin embargo, también se concluye que la formación pedagógica no presenta diferencias frente a la educación inclusiva, pudiéndose inferir que la formación pedagógica es indiferente para alcanzar maestros con enfoque inclusivo.
