Ratio Optimization of Magnesium Oxychloride Cement and Improvement of Its Water Resistance Based on Response Surface Methodology
Authors: Junfang Fu  , Rongyao Chen
Published: January 2024

Magnesium oxychloride has excellent early strength, lightweight and environmentally friendly properties, and excellent application value. However, insufficient water resistance affects its engineering application. This paper uses fly ash to improve the water resistance of magnesium oxychloride cement (MOC). The response surface method was used to optimize the ratio of magnesium oxychloride cement. The influence of fly ash content, magnesium oxychloride cement ratio, and their interaction on the water resistance of magnesium oxychloride cement was studied using a response surface experiment. The fly ash content and magnesium oxychloride cement ratio were optimized to form magnesium oxychloride cement with good water-resistance. The experimental results show that the fitting efficiency of the response surface model is R2 = 0.9951; the model reflects the relationship between the factors of magnesium oxychloride cement and water resistance well. The magnesium oxychloride cement has a maximum softening coefficient of 0.898 when the amount of fly ash added is 21.94%, and the molar ratio of magnesium oxychloride cement is 11.49: 1:11.77. The magnesium oxychloride cement has good water resistance by optimizing the ratio based on external fly ash and response surface methodology. The study provides a reference for improving the water resistance of magnesium oxychloride cement.

Weeds are disregarded for their competitive nature and difficulties during harvesting and threshing. Categorizing them by economic use classes enables effective management. Weed ecological studies in wheat crop fields were conducted to evaluate the floristic diversity, ecological characteristics, community structures and economic uses of weeds in District Nowshera, Pakistan. Different wheat crop fields were surveyed for the collection and identification of plant species growing as weed. Total 50 plant species from 47 genera and 20 families were recorded in the study area. Asteraceae had the highest number of species (10), followed by Poaceae (9). Therophytes were more with 42 species, followed by geophytes and Hemicryptophytes each with 3 species. Most species had mesophyllous leaf size (15), while nanophyllous (12) and microphyllous (11). Simple leaves were more common (28) than dissected leaves (22). Nonspiny species were (44) while only 6 had spines. Maximum plant species were fodder (35) and medicinal (10). In the study, four distinct weed communities were identified using quadrate method i.e. Cynodon-Anagallis-Melilotus, Arenaria-Anagallis-Cannabis, Cynodon-Parthenium-Coronopus and Rumex-Arenaria-Oxalis. These findings provide a valuable starting point for future in-depth investigations on the entire flora and vegetation of Nowshera, Pakistan.

The circular economy and sustainable development are critical issues today, given the growing environmental pollution caused by solid waste, especially plastics. Furthermore, plastic waste has raised significant social concerns and alerted plastic product designers. Therefore, developing or redesigning plastic products in the flexible packaging industry is imperative to ensure their recyclability at the end of their life cycle. It is necessary to ensure that the mechanical and barrier properties of the ecological plastic packaging remain intact for specific uses. The current study aims to redesign flexible packaging, focusing on providing the mechanical and barrier properties of the packaging suitable for food industry applications, thus offering a solution through new design proposals that allow the development of sustainable and flexible packaging, emphasizing material reduction and recyclability. This study assessed and compared the mechanical properties of the proposed packaging with those of existing products. The results demonstrated the feasibility of reducing plastic film thickness or eliminating layers in a tri-laminated structure and transitioning to a bi-laminated structure. This adjustment did not compromise the mechanical and barrier properties; the oxygen barrier remained at 35.39 cc/m2*day, and the humidity stood at 0.57 mg/m2*day. This investigation led to a 26.48% reduction in the raw material consumption of laminated coils and 12.68% in Doypack type packaging used in food applications. Consequently, the decreased material usage and adoption of monomaterial structures significantly minimized the environmental impact of plastic waste contamination due to the possibility of mechanically recycling the final product.

ABSTRACT

MANAGEMENT OF CHYLOUS LEAKAGE AFTER AFTER LAPAROSCOPIC DONOR NEPHRECTOM

Background: If Postoperative chylous leakage not treated properly, they can lead to severe complications such as dehydration, malnutrition, immune dysfunction..., we have 9 cases of postoperative hemorrhagic leakage, from mild to severe cases requiring intervention. We would like to share our treatment experience at the Viet Duc Hospital regarding the issue of managing of chylous leakage after after laparoscopic donor nephrectomy

Methods: A retrospective study was conducted on 167 laparoscopic kidney donors from June 2021 to June 2022. Clinical cases with delayed graft function were described. Study variables included recording information during surgery and post - surgery: age, gender, surgical characteristics, and progression during and after the treatment process. Patients were treated according to a standardized protocol.

Results: Postoperative delayed graft function was diagnosed in 09 cases. This complication was mostly observed on the left side rather than the right (89%). The average time of delayed graft function onset was 2.3 days after surgery. 7 cases were managed with intravenous fluid and dietary adjustments, and their hospital stay was under 10 days. In 2 cases with delayed graft function exceeding 1 liter per day, intervention through vascular access was conducted. Discharge outcomes were stable for all cases.

Conclsusion: Chylous leakage is a rare complication after laparoscopic donor nephrectomy so treated early because it can lead to serious consequences for the patient. Embolise chylous is the ultimate treatment measure for this patient
Rural Early Childhood Educators’ Perception of Music-Based Pedagogy in Teaching Communication Skills to Children

Published: January 2024

Early childhood care and Education is an important phase for impacting communication skills to children for building a strong sense of identity and belonging. The South African National Curriculum Framework (NCF) regards communication skills as one of the six early learning and development areas considered for Early Childhood and Education (ECCE). Caps Grade R admonishes educators to support learners with interpersonal Communication Skills and to develop their Cognitive Academic Language Proficiency by engaging them in activities that focus on rhymes. Thus, South African children need skillful educators to employ developmental implementation strategies to support their acquisition of these skills. Research shows that subjects like Life Skills, English Language, Civic Education, and Mathematics are successfully implemented using music-based pedagogy. However, because ECCE is relatively new in South Africa, there is no strong structure to support the ECCE/ECD (Early Childhood Development) educators in employing music-based pedagogies to teach communication skills to the children. This article focuses on the rural ECD/ECCE educators’ perception and experiences in employing music-based pedagogy to support the children’s acquisition of communication skills. The study was conducted at two ECD/ECCE centres in Northern Cape province, South Africa.This is participatory visual research where Six ECD/ECCE Educators were engaged in semi-structured interviews and reflective activities on how they facilitate communication skills using music. The study was informed by Vygotsky’s sociocultural theory. The educators supported music-based pedagogy, however, inadequate musical training, non-availability of musical resources, and non-inclusion of music as an independent subject in the CAPS/NRF documents are their constraints. In their pre-service teacher education programs, almost all South African institutions include creative arts training; the course is typically taught over one semester, and music is merely one of the various creative arts subfields. As a result, the pre-service teachers lack the necessary musical background to implement music-based instruction. In conclusion, the study recommends musical intervention training to empower ECD/ECCE educators.

Authors: Widiastuti Linda , Atrie Utari Yunie , Wati Liza , Sitindaon Soni Hendra , Arianingsih Tri , Mulyana Budi Mulyana
Published: January 2024

BACKGROUND: The critical care patients often have unpleasant experiences while facing critical care activities that may impact on physiological and psychological changes. Music therapy is a simple complementary therapy that can promote relaxation, potentially affecting some outcomes for critical care patients. However, a systematic review related to the application of music therapy and the results obtained from music therapy is still limited.
AIM: This systematic review aimed to explore and evaluate the effectiveness of music therapy interventions in relieving symptom experiences and improving outcomes of critical care patients.
METHODS: We conducted a systematic review of research articles focused on music therapy in critical care areas using three electronic databases, namely PubMed, CINAHL, and Science Direct. We selected English articles that had a Randomized Control Trial (RCT) design and published from 2005 to 2020. PICO format used to search literature; “Adult, Critical Care, Intensive Care Unit (ICU), Critically Ill Patients, Intensive Care, Surgical ICU, Cardiac Surgical ICU, Medical-Surgical ICU, Therapy Music, Music Therapy, Pain, Agitation, Stress. Anxiety, Delirium, Mobility, Sleep, Physiological, and Psychological. The risk of bias from 19 articles was evaluated by JBI. Furthermore, we assessed the manner and effect of music therapy on various symptoms.
RESULTS: The researchers found 743 articles. After manual review, 19 RCTs (1711 participants) were identified and assessed. Based on the review, it was reported that music with a relaxed rhythm, soft tone, slow rhythm; duration from 15 to 60 min; 60–80 beats/min, and using headphones, has a significant effect on pain, anxiety, stress, delirium, mobilization, sleep quality, sedation levels, and physiological parameters.
CONCLUSION: Music therapy has proved effective in reducing symptoms experiences of critical care patients. It is suggested to be used as a viable option in symptoms management of patients in ICU.

Authors: Sudharta Harvey , Darmawan Octavianus , Barus Jimmy F. A.
Published: January 2024

AIM: This systematic review aimed to clarify the association between tyramine ingestion (food/capsule) with the occurrence of a migraine attack.
METHODS: Based on a comprehensive search of PubMed, PMC, ProQuest, and EBSCOhost, we included all studies that observed migraine headaches after tyramine ingestion. Association was evaluated with the control (placebo) group as a comparison. We further assessed the abstracts and full texts of selected papers. We included articles fulfilling the inclusion criteria in this systematic review.
RESULTS: Seven non-randomized studies with 322 eligible subjects (168 women, 63 men, and 91 unknown genders) aged 4 to 62 years old were included in the study. A high to moderate (17.2–50%) occurrence of headache after tyramine ingestion was observed. Similar results were observed in the control (placebo) group (0–42.1%). Quality appraisal on all seven non-randomized studies using ROBINS-I showed that six studies had a moderate risk of bias, and one study had a serious risk of bias.
CONCLUSION: The relationship between tyramine-containing food and migraine remains unclear.

Authors: Christina Michal , Ibrahim Mohd Yusof , Karim Haryati Abdul , Dhanaraj Prabakaran
Published: January 2024

BACKGROUND: Undocumented migrant families face many challenges in bringing their children for vaccination. The recent outbreak of poliomyelitis in Sabah among undocumented migrant children highlights the gap in vaccination coverage among these populations.
AIM: This study aimed to determine the factors that influence undocumented migrants in Sabah to vaccinate their children.
METHODS: This is a cross-sectional study using a questionnaire developed based on the findings from a qualitative study. This study was conducted in 15 districts of Sabah among the mothers of undocumented migrant children. Multiple Logistic Regression was done to find out the significant factors that influence undocumented migrants to vaccinate their children.
RESULTS: A total of 942 responses were collected during the study. About 78.7% of the respondents attended health facilities to vaccinate their children. Only the legal status of the undocumented migrant (adjusted odds ratio [aOR] = 0.15 [95% CI: 0.52–0.43]) remains a significant militating factor for undocumented migrants to vaccinate their children. Two factors, parental trust in health-care providers and vaccines (aOR = 18.24 [95% CI: 8.42–39.51]) and good support system (aOR = 2.65 [95% CI: 1.77–3.97]), remain significant motivating factors that influence undocumented migrants to vaccinate their children. Those who had visited the health facilities for an antenatal check-up (aOR = 25.93 [95% CI: 17.07–39.39]) and delivery (aOR = 93.63 [95% CI: 34.77–257.81]), with income of more than RM 1000 (aOR = 6.09 [95% CI: 3.66–10.12]) have a higher prevalence to bring their children for vaccination.
CONCLUSION: In the best interest of public health and to prevent the further re-emergence of vaccine-preventable diseases in Sabah, it is important to address these factors to improve vaccine uptake among undocumented migrant children.

Authors: Dusak I Wayan Suryanto , Wiradiputra Agus Eka , Putra Gusti Ngurah Paramartha Wijaya , Wangsa I Gde Made Satya
Published: January 2024

AIM: The objective is to compare the outcomes of intra-articular injection of mesenchymal stem cells (MSCs) to platelet-rich plasma (PRP) as a treatment modality for knee osteoarthritis (OA).
METHODS: Systematic review was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses and PICO criteria for the past 10 years of publications. Keywords used to search with Boolean operator: “knee OA” AND “MSCs” AND“PRP” AND “outcome.” All selected articles were assessed for their quality based on strengthening the Reporting of Observational Studies in Epidemiology checklist.
RESULTS: We selected five articles of prospective cohort studies, which involved 54 patients whom received combination therapies of MSCs+PRP, 206 patients received MSCs only treatment and 86 patients received PRP only treatment. It was shown that MSCs had superior outcomes compared to PRP treatment in terms of VAS and KOOS, where combinations of MSCs and PRP treatment had no significant difference compared to the MSCs treatment alone. Nonetheless, each treatment showed a significant improvement of KOOS, VAS, WOMAC, IKDC, knee, and function knee scores from their baselines.
CONCLUSION: Intra-articular injections are effective and safe for the management of knee OA. MSCs treatment has superior effect on the treatment outcomes compared to PRP treatment. Combination of both treatments is comparable to MSCs treatment alone.

Published: January 2024

BACKGROUND: Currently, periodontal disease during pregnancy is associated with gestational diabetes, low birth weight, and pre-term birth.
AIM: The aim of this study was to determine the difference in the level of knowledge about periodontal disease prevention, before and after applying a motivational educational intervention in pregnant women at a primary health-care center.
METHODS: Quasi-experimental study in 180 pregnant women from a health center, during the period September to December 2022. The data collection technique was a questionnaire survey with satisfactory characteristics of validity and reliability. An educational intervention with a motivational approach was developed, which was validated in a pre-liminary pilot test. The Wilcoxon statistical test was used to compare knowledge before and after the intervention, and the Chi-square test to assess the association between variables.
RESULTS: The age and educational level that pre-dominated were 21–30 years and complete secondary school, respectively. A significant difference was found between the level of knowledge before and after in pregnant women (p < 0.001). There was no association between the level of knowledge about periodontal disease prevention with age and educational level in pregnant women at the health center, before and after a motivational intervention (p > 0.05).
CONCLUSION: The motivational educational intervention managed to significantly improve the level of knowledge in pregnant women about the prevention of periodontal disease; however, it was not associated with age and educational level.
