Methodology: This study utilized a 1descriptive research approach and 1inferential 1design through a 1field survey, employing two distinct 1sets of questionnaires. One was administered 1to the key informant and the other to Persons Living with HIV (PLHIV).1Spearman’s 1rho 1correlations 1and simple linear1regression1models were also applied to assess the association between voluntary engagement as 1the independent variable and communication as the 1dependent 1variable. ANOVA 1test 1was also performed 1to test the hypothesis 1and results were 1presented 1in 1tables.

Findings: The study comprised a sample size of 376 individuals, constituting 96.18% of willing respondents who agreed to participate in 1interviews. Seventeen unresponsive records were excluded from the analysis. A Normality 1Test was conducted to assess whether the study sample was drawn from a population with a normal distribution. Under the 1null 1hypothesis, no significant difference was found between the sample and the population it represented. Consequently, there was substantial evidence to reject the 1null 1hypothesis and accept the 1alternative 1hypothesis (p-value=0.000 CI=95%). Moreover, the findings revealed that 82.30% voluntarily enrolled in the 1Text 1for 1Adherence (T4A) 1mobile 1app, 70.71% signed the consent form, and 6.07% indicated that 1consent was implied.

Unique Contribution to Theory, Practice and Policy: This study extends 1Technology readiness theory studies to mhealth field where it is beginning to gain traction. It also indicates the significance of individuals willingly participating in mHealth interventions upon enrollment. Voluntary participation is an imperative condition of any research undertaking. This study's results additionally confirmed that mHealth interventions enhance the well-being of individuals managing chronic illnesses. This study is likely to inform policy changes and or amendments in the mhealth space in many jurisdictions. An 1intervention 1such 1as 1Text for1Adherence (1T4A) may encourage 1the 1government 1to support system developers. It can also take over the project as a public health investment instead of leaving it to private sector or non-governmental organizations. Study further extends the body of knowledge in use of mhealth interventions.

Authors: Cubillas Franz Dinar V.
Published: January 2024

This research meticulously explores the complex terrain of disruptive learning encounters among non-STEM psychology students at Father Saturnino Urios University (FSUU), aiming to unravel the intricate moderating factors that shape the relationship between disrupted learning progression and psychological challenges. Situated within the framework of the K to 12 Program, which introduced diversified tracks in secondary education, students were empowered to align their academic pursuits with their unique aptitudes and career aspirations. Nevertheless, a pronounced misalignment between senior high school strands and subsequent college courses, particularly within STEM fields, has emerged as a notable concern. Guided by the theoretical underpinning of the vertical alignment theory, this study posits that the misalignment between high school strands and college courses not only adversely impacts academic performance but also engenders psychological challenges. Embracing an Exploratory Sequential Mixed Method Design, the research seamlessly integrates qualitative and quantitative methodologies, commencing with a qualitative exploration to inform subsequent robust quantitative measures. The findings of this study hold significance in unveiling nuanced factors underpinning disruptive learning, with the potential to inform educational policies and practices, fostering inclusive experiences for diverse student cohorts.

Cholesterol is a soft, pale yellow steroid fat that exists in the body's cell membranes and is transported in the plasma of most animals. This compound plays an important role in the physiology of the human body. However, excess cholesterol in the diet is also one of the leading causes of cardiovascular diseases. Therefore, the quantification of cholesterol in foods and functional foods is essential so that consumers can choose a diet containing the right amount of cholesterol. This study used gas chromatography-mass spectrometry to quantify cholesterol, with ISQ 7000 GC-MS system, TraceGOLD TG-5MS chromatographic column, and electron impact (EI) ionization mode. The validity of the method was confirmed according to the guidelines of the Association of Official Analytical Collaborations (AOAC). The results showed that the method has good specificity, the linearity range from 5 to 100 μg/mL in working solution, the detection limit of 1.5 to 15 mg/kg, the quantification limit of 5.0 to 50 mg/kg, depending on the matrix; the method's recovery were from 92.6 to 108.4% and the precision has relative standard deviations of 1.18 - 2.84%, meeting the requirements of AOAC. The method was used to analyze samples of dairy foods and functional foods randomly purchased in the market.

In this work, a GC-MS/MS-based analytical method using accelerated solvent extraction combined with multi-layer silica gel column for sample preparation was developed to simultaneously determine 20 organochlorine pesticides (OCPs), 28 polychlorinated biphenyls (PCBs) and 8 polybrominated diphenyl ethers (PBDEs) in fish tissue. The method detection limits (MDLs) were achieved in the range of 0.053 ng/g (α-chlordane) – 1.65 ng/g (δ-BHC), 0.07 ng/g (PCB-209) – 1.84 ng/g (PCB-28), 0.323 ng/g (BDE-209) – 0.796 ng/g (BDE-47) for OCPs, PCBs and PBDEs, respectively. Intra-day and inter-day repeatability of the analytical signal (peak area) were below 10.5% and 12.4%, correspondingly. The overall recovery was investigated by spiking experiments and ranged from 70.9 to 114%. The confirmation of this developed method was assessed by analysis of the standard reference material (SRM-1947) sample. The measured concentrations of target compounds were within the range of the certified values. This developed method was applied for analysis of OCPs, PCBs and PBDEs in five fish tissues collected randomly from local markets at Hai Phong province. Their concentrations (<MDL – 206 ng/g for OCPs, <MDL – 20.7 ng/g for PCBs and <MDL – 66.7 ng/g for PBDEs) were lower than the maximum residue levels permitted by European Union, Food and Agriculture Organization and World Health Organization.

Published: January 2024

Os autores estudaram 15 casos de hanseníase tuberculóide reacional (13) e dimorfa reacional (2) que ulceraram (12 mulheres e 3 homens, entre 30 e 76 anos). Chamam a atenção para a escassez de trabalhos na literatura sobre esse tema e descreveram os aspectos clínicos desses casos, os resultados da baciloscopia, histopatologia e do teste de Mitsuda. Eles enfatizaram a predominância de pacientes com imunidade mais alta, ou seja, aqueles que exibiam baciloscopia negativa e a reação de Mitsuda igual a 6 mm ou mais. As ulcerações apareceram, na maioria das vezes, durante o 29 ou 39 surto reacional. A opinião dos autores é de que as reações hansênicas tipo 1 são manifestações de hipersensibilidade que ocorrem devido à multiplicação bacilar, seguida de sua destruição pelas defesas orgânicas ou pela terapêutica e a conseqüente liberação de epítopos, que desencadeariam o fenômeno reacional. Eles sugeriram para explicar o aparecimento de ulcerações em seus pacientes duas possibilidades. A primeira seria uma estimulação continua dos macrófagos, podendo levar ao dano tecidual através da produção de intermediários reativos do oxigênio e hidrolases, que é devida ao aumento na produção de TNFa. A outra possibilidade seria admitir que esses casos que ulceram constituam um grupo geneticamente relacionado que apresenta homozigose para o alelo TNFB2, o qual se relaciona com indivíduos que apresentam concentrações plasmáticas altíssimas de TNFa, quando comparados com indivíduos heterozigotos e indivíduos homozigotos para o alelo TNFB1.

Summary: Introduction: Bariatric surgery is the most effective treatment for the morbid obesity. It results in sustained weight loss as well as pronounced effects on obesity-related comorbidities. In the last twenty years the number of procedures performed worldwide increased. Therefore, the effort to establish a consensus in perioperative care based on best evidence in this issue is evident. Methods: Working Group of Joint Section of Bariatric and Metabolic Surgery of Czech Surgery Society and Czech Obesitology Society reached practical recommendations for ERAS (Enhanced Recovery After Surgery) in perioperative care in bariatric surgery. It issued from ERAS recommendations published in 2021. Working group adopted the original text, consequently adapted and in particular cases affixed its commentary. The electronic voting of all members of working group was the final phase, by which the strength of consensus of particular elements was expressed. Results: The Czech working group reached the consensus with recommendations ERABS (Enhanced Recovery After Bariatric Surgery) in the most elements. For some interventions of ERAS protocol for bariatric surgery the quality of evidence is low. Therefore, evidence-based practices may need to be extrapolated from other surgeries. Conclusion: The recommendation is appointed for clinical practice in bariatric surgery with protocol ERAS based on updated evidence and recommendations. It is based on recent and comprehensive ERAS recommendation, which was adopted and adapted by the Czech working group of Joint Section of Bariatric and Metabolic Surgery of Czech Surgery Society and Czech Obesitology Society. The Czech version contents some supplementations and specifications in commentaries. Original article was published in Rozhledy v chirurgii [1].

High iNOS and IL-1β immunoreactivity are features of colitis-associated colorectal cancer tumors, but fail to predict 5-year survival
Authors: Björner Kajsa , Chen Wei-Na , Gannavarapu Venkata Ram , Axling Fredrik , Gulyas Miklos , Halim Mohammad Abdul , Webb Dominic-Luc , Hellström Per M.
Published: January 2024

Background: Inflammatory bowel disease (IBD; mainly ulcerative colitis and Crohn’s disease) is associated with the development of colorectal cancer (CRC) referred to as colitis-associated colorectal cancer (CAC). In inflammatory flares of IBD, the production of luminal nitric oxide (NO) increases due to the increased inducible nitric oxide synthase (iNOS) activity in inflamed tissue. It is believed that iNOS parallels pro-inflammatory interleukin-1β (IL-1β). How these biomarkers relate to CAC pathogenesis or survival is unknown.

Aim: The primary aim of this study was to investigate iNOS and IL-1β immunoreactivity in CAC tumors in comparison with CRC and normal colonic mucosa, and the secondary aim was to determine if immunoreactivity correlates with 5-year survival of CAC.

Methods: Immunohistochemistry was performed on tissue sections as follows: CAC (n = 59); sporadic CRC (sCRC) (n = 12); colonic mucosa >2 cm outside sCRC margin (normal mucosa) (n = 22); paracancerous IBD (pIBD) (n = 12). The expression of iNOS and IL-1β was quantified separately for epithelium and stroma. Data were evaluated using the Mann-Whitney U-test and the log-rank test for 5-year Kaplan-Meier survival curves. Results were compared with online mRNA databases.

Results: Immunoreactivity occurred predominantly in epithelial cells and to lesser extent in stroma. Compared with normal mucosa, immunoreactivity for iNOS (P < 0.01) and IL-1β (P < 0.005) was higher in CAC epithelium. In CAC stroma, iNOS immunoreactivity was lower than normal mucosa (P < 0.001), whereas IL-1β was higher (P < 0.05). Immunoreactivity differences of iNOS or IL-1β among CAC patients failed to correlate with 5-year survival. These findings were supported by online mRNA databases.

Conclusion: Consistent with high NO production in IBD, there is more iNOS in CAC epithelium, albeit not in stroma. This immunoreactivity difference exists for IL-1β in both epithelium and stroma. The intervention of arginine or iNOS activity for CAC chemotherapy is not straightforward.

¿Nuevas cartografías del tiempo?: historicidad, conflictos y apertura de posibilidades
Authors: Medel Barragán Daniel
Published: January 2024

A partir de una lectura cruzada entre el reciente libro de Berber Bevernage, Historia, memoria y violencia estatal. Tiempo y justicia, y algunas premisas surgidas del reciente “giro temporal” en la reflexión teórica de la historia se plantean vías o contextos de lectura para contextualizar las premisas sobre las temporalidades espectrales.
El primero de estos contextos consiste en la idea de que los movimientos sociales esgrimen diversas temporalidades en los espacios públicos para configurar distribuciones nuevas de las memorias y las duraciones o persistencias de pasados difíciles. En este sentido, se observa que las temporalidades siempre se configuran desde espacios agónicos o de constante disenso asediados por los espectros de pasados difíciles.
El segundo contexto de lectura es  inscribir las premisas de Bevernage sobre los tiempos espectrales en cuatro sensibilidades que territorializan las actuales postulaciones de las temporalidades: a) el conflicto y la apertura de posibilidades; b) las heterocronías y espectrologías; c) las temporalidades post-naturales; d) temporalidades queer. Desde estas claves de lectura se comenta el planteamiento espectral y derrideano de Bevenarge, la crítica al tiempo modernista y los binarismos entre ausencia/distancia y presencia/ausencia. En paralelo, se plantean algunas interrogantes necesarias para las operaciones historiográficas contemporáneas que pasan por la dimensión ética del tiempo y los fantasmas de los pasados violentos, coloniales, racistas y de la precariedad.

Tiempo del mundo/tiempo del antropoceno. Lo simultáneo de lo no simultáneo
Authors: Hartog François
Published: January 2024

Este ensayo se pregunta por la problemática que la era del Antropoceno le ha venido a plantear al tiempo histórico. ¿Cómo comprender la copresencia de dos medidas del tiempo inconmensurables? Por un lado, tenemos el tiempo del mundo (la historia) y, por otro, el tiempo de la tierra (Antropoceno). Esta experiencia de la desarticulación de la temporalidad es la expresión de situaciones de crisis. Para reflexionar sobre esta crisis actual se estudia la temporalidad de “lo simultáneo de lo no simultaneo”, la cual, es la experiencia fundamental de la historia. Para reflexionar sobre estos dos tiempos que caminan de forma paralela se recorren las maneras en que ha tenido desde Homero hasta la era contemporánea pasando por el tiempo cristiano la temporalidad del tiempo que se expresa en “lo simultáneo de lo no simultáneo”

Authors: MUSSI STOIZIK Jessica Anabella , AVENA Maria Virginia , ELIAS María Lucia , HEREDIA Rocio , BOARELLI Vanina Paola
Published: January 2024

Background: Ketogenic diets have a long history of therapeutic use and have recently attracted significant attention due to their promising effects on a variety of disorders. However, no definitive links have been identified. This review aims to highlight the possible impacts of ketogenic diets as well as the mechanisms involved in metabolic processes and related non-communicable metabolic diseases. Methods: For our analysis, a bibliographic review of articles about ketogenic diets and their therapeutic effect on chronic pathologies was carried out, retrieved from the scientific literature. Results and discussion: These studies found both positive and negative outcomes for the effects and implications of ketogenic diets on metabolism. Significant differences in metabolic markers such as weight, glycemia, serum lipids and lipoproteins, anthropometric measures, and hormones such as insulin, leptin, and adiponectin have been reported. In addition to changes in the microbiome that have modest to moderate concurrent effects, changes in metabolism indicate the significance of dietary changes in treating and preventing chronic non-communicable diseases. Conclusions: In this review, we present the available scientific evidence on the effects of the ketogenic diet, and thus ketone bodies, on metabolism and related chronic diseases.

Published: January 2024

Digital Twins (DTs) are gaining popularity because they provide precise digital copies of assets, processes, and systems. This is especially true when these DTs are paired with real-time simulation models that make use of modern technologies like machine learning, artificial intelligence, and data analytics. These combinations can provide a comprehensive and dynamic view of the monitored systems. Digital twin (DT) has shown tremendous potential to bring about revolutionary improvements in the field of construction site surveillance. There is, however, a notable paucity of empirical research identifying the constant elements affecting DT adoption in this industry. This research tries to fill that void by identifying the important elements that determine the usage of DT in construction. The study adopts a complete framework with the goal of increasing the use of DT in building site monitoring. The elements influencing the adoption and effectiveness of distributed ledger technology (DT) are divided into three categories: technological, organizational, and economic. Technological factors include the system's appropriateness and the robustness of the data infrastructure. Organizational considerations include the company's openness to innovation and leadership support. Economic aspects include things like return on investment (ROI) and cost-effectiveness. The research technique combines case studies and literature reviews to examine the benefits and drawbacks of DT in construction monitoring. This study's expected output is a comprehensive framework that aids construction businesses in optimizing the use of DT in site monitoring. This would allow for more efficient, data-driven, and forward-thinking processes. The study's ultimate purpose is to provide critical knowledge that will assist the building sector in adopting cutting-edge methods. The industry may better plan for the integration of this sophisticated technology into their operations by knowing the potential of DT and the variables driving its adoption. This, in turn, can lead to more efficiency, lower risks, and improved overall performance

Published: January 2024

One of the oldest and most important sectors of a country's economy is the construction sector. Through infrastructure projects, amenities, and real estate development, the Indian construction industry contributes significantly to the country's economic growth and nation-building. India is trailing behind the west in the application of robotics and automation in construction, while the west is seeing a rise in this field. An examination of the particular reasons limiting adoption in Indian building projects is presented in this research. The objective of the review is to identify and categorise the most critical challenges that are limiting the adoption of robotics in construction projects. The information provided will help those working in construction come up with mitigation plans. The results show that, while there is awareness of the benefits of adaptability and the use of robots in construction, there are a number of resistance factors that must be overcome for robotics to be successfully adopted in India. Generally speaking, professionals in the construction industry consider automation and robotics to be synonymous, and they believe that robotics is appropriate for a developing nation like India

Is there a relationship between chronic low back pain and spinal sagittal balance? A prospective controlled study
Authors: Korkmaz Taha Şükrü , Akkaya Süleyman
Published: January 2024

Aim: Evaluation of whether there is a significant relationship between chronic low back pain and spinal sagittal alignment.
Methods: This prospective, controlled study was conducted between April 2023 and September 2023, among patients aged 18–50, who complained of chronic low back pain and a healthy control (HC) group. In addition to the participant's demographic information, sagittal vertical axis (SVA), thoracic kyphosis (TK), and lumbar lordosis (LL) values on the lateral whole-spine radiograph and degenerations on the lumbar vertebra MRI were compared. VAS and ODI scores of the patients were also included in the statistical evaluation.
Results: A total of 64 participants (44 patients, 20 controls) were included in the study. There was no significant difference in age, gender, body mass index (BMI). SVA significantly increased in the patient group (p < 0.001), but not LL and TK. In a linear discriminant analysis (LDA), SVA discriminates 100% of the two groups. No significant correlation was observed between VAS and ODI scores and the patient's age, gender, BMI, and spinal parameters.
Conclusion: SVA is a crucial parameter of spinal balance, and as shown in this study, deviations from normal SVA appear to be a significant contributor to low back pain. We recommend an easy-to-implement and cost-effective method for assessing SVA in evaluating and treating patients with chronic low back pain.
Pneumonies

Published: January 2024

Pneumonia is an inflammation of the alveolar space distal to the terminal bronchiole in the lung parenchyma. The inflammation seen in pneumonia is mostly caused by microorganisms such as viruses, bacteria, and fungi, but can also be caused by non-infectious causes (toxic substance inhalation, radiation damage, hypersensitivity reaction-pneumonitis, autoimmunity). Pneumonia can be observed in three forms: community-acquired pneumonia (CAP), hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP). Patients with pneumonia usually present with cough, fever, sputum, chest pain, dyspnea, and hemoptysis. In addition, patients may have nonspecific symptoms. CAPs are caused by typical (S. pneumoniae) and atypical (C. pneumoniae, M. pneumoniae, and L. pneumoniae) agents. On presentation, fever, pulse rate, respiratory rate, oxygen saturation, blood pressure, and auscultation should be performed. Typical chest radiographic findings in the diagnosis of CAP include lobar consolidations, interstitial infiltrates, and/or cavitations. Acute-phase reactants may be elevated in response to infection and inflammation in pneumonia. The first decision to be made in cases of pneumonia is the determination of the need for hospitalization and the choice of antibiotherapy. If possible, cultures should be taken before antibiotics are started on the patient for whom hospitalization is planned. After 72 hours, in patients with no symptom improvement, the reason for treatment non-response should be evaluated, and antibiotherapy should be changed if necessary.

This study investigates the impact of incorporating Geometer's Sketchpad into GSP-based instruction on the algebraic reasoning proficiency of students. The research outlines the application of GSP-based instruction, utilizing Geometer's Sketchpad in Mathematics education, with a specific focus on solving quadratic problems. A quasi-experimental design, involving non-equivalent pre-test and post-test assessments, was conducted on 60 second-grade students at a private secondary school in Kuala Lumpur. The experimental group, consisting of 30 students, utilized Geometer's Sketchpad in their learning, while the control group, comprising 30 students, received traditional instruction. Data analysis was performed using ANATES 4 and SPSS 25.0 software, incorporating inferential statistics such as paired t-tests and one-way ANCOVA for quantitative data analysis. Both groups underwent an initial pre-test assessment. The research findings reveal a significant disparity in algebraic reasoning proficiency between the two groups, indicating substantial improvement after the intervention. Consequently, the integration of Geometer's Sketchpad in GSP-based instruction contributed to the enhancement of students' algebraic reasoning skills, particularly in quadratic problem-solving. In conclusion, this study underscores the potential of Geometer's Sketchpad as an instructional intervention, urging mathematics educators to contemplate its incorporation as an alternative teaching tool.
