DRIED NATA DE COCO WITH WATER ABSORPTIVITY COMPETING SILICA GEL
Authors: Rahmayanti Handika Dany , Yuliza Elfi , Amalia Nadya , Abdullah Mikrajuddin 
Published: September 2024

Nata de Coco (NDC) is a network of cellulose fibers that traps abundant of water. If a freshly made NDC is dried to remove nearly all trapped water, we will get a very hygroscopic material. This material is potential for making water adsorber that might compete the well known silica gel. NDC was prepared using standard methods and its water absorption was investigated. Dried NDC was used in this study. For comparison, we also investigated the water absorption of several commercial NDC. To determine its business prospects, the water absorption of silica gel was also investigated. The results showed that dried NDC could absorb water vapor comparable to the absorption of commercial silica gel. This suggests that dry NDC has the potential as an alternative water vapor absorber in food packaging. The advantages of the NDC compared to silica gel are safer and environmentally benign, and easily decomposed.

Authors: AL-jumaili Miqdam M Obaid 
Published: September 2024

Objective: The study aimed to investigate the correlation between Helicobacter pylori (H. pylori) and thyroid autoimmunity. Material and Methods: To demonstrate the possible correlation between H. pylori infection and autoimmune hypothyroidism, 200 individuals were enrolled in this research (100 patients with active H. pylori infection and 100 healthy controls). All of them were tested for serum levels of thyroid hormones, thyroid stimulating hormone (TSH), and autoantibodies, as well as Helicobacter pylori-Immunoglobulin G (H. pylori-IgG) and cytotoxin-associated gene A-Immunoglobulin G (cagA-IgG) antibodies. Results: The study found that H. pylori infection was associated with higher levels of TSH, thyroperoxidase and thyroglobulin (TPO and TG) (p-value<0.000, 0.001 and 0.006, respectively) and a significant decrease in the levels of free-thyroid hormone (FT3 and FT4) (p-values=0.008 and 0.007 respectively) in patients compared with the control group. Moreover, using Pearson’s correlation tests, significant proportional correlations were found between H. pylori IgG and TSH (r=0.302, p-value=0.001), and a significant negative correlation was found between anti-H. pylori-IgG and with FT3 and FT4 (r=-0.261, p-value=0.003 and r=-0.260, p-value=0.003, respectively). Moreover, Spearman’s correlation results showed that H. pylori IgG was positively linked to TPO (r=0.531, p-value<0.001) and TG (r=0.320, p-value=0.001). Conclusion: The current investigation found that H. pylori infection was linked to higher concentrations of thyroid autoantibody and TSH and lower levels of thyroid hormones, suggesting that the bacterium may play a role in the development of subclinical autoimmune hypothyroidism.

Published: September 2024

Concrete sandwich panels consist of two concrete layers separated by an insulating foam core, offering thermal insulation, structural strength, and fire resistance. This study investigates sustainable precast concrete sandwich panels made with industrial waste materials like limestone slurry, quarry waste, and basalt fiber as shear connectors. The research evaluates the flexural and axial strength behavior of these panels and explores strategies to improve their structural performance. The panels were fabricated with outer concrete layers, an expanded polystyrene (EPS) insulation core, and basalt fiber connectors. Flexural tests using four-point bending and axial compression tests were conducted on panels with varying concrete layer thicknesses and basalt fiber widths. Findings revealed panels with thicker outer concrete layers (35mm) and wider basalt fiber connectors (11.5mm) exhibited higher cracking loads, load-hardening behavior, and increased ductility compared to thinner layers and narrower connectors. The axial test showed premature failure at the top and bottom quarters. Thicker concrete layers and wider basalt fiber connectors enhanced crack control, load distribution, and ductile behavior under flexural loading. Strengthening measures like additional reinforcement, proper anchorage detailing, and increased shear reinforcement at the end regions are recommended to improve axial load-bearing capacity and prevent premature end failures. The PCSP demonstrated up to 40% cost savings over commercial products while providing better thermal insulation than conventional brick masonry due to the EPS core. Overall, the study promotes developing sustainable, energy-efficient, and cost-effective load-bearing sandwich panel systems.

Published: September 2024

Physical activity supports health and wellness, and specifically supports healthy aging. Little is known about the experiences of older Métis adults with physical activity through their lifespan and how this has impacted wellness. This study was co-constructed with 12 older Métis adults in Sakitawak (Île-à-la-Crosse) Saskatchewan using a participatory action approach, two-eyed seeing and the ontology of Breath of Life Theory, as described by Cindy Blackstock. Older Métis adults described physical activity within three themes, Wahkotowin (Related to Everything), Ahkameyimowin (Never Give up), and E ti Meyo Matshohot (Becoming/Living a Better Life). The results of this study have implications for health care professions which are founded within biomedical and biopsychosocial models. We consider the context and experiences of physical activity among Indigenous populations in Canada to better address the gaps and identify practices that aim to support population health.

Published: September 2024

Indigenous peoples in Canada experience disproportionately higher rates of hospitalization for mental health and substance use concerns than non-Indigenous populations. Ambulatory care sensitive conditions are community-level markers of mental illness which can theoretically be managed through community-based health services, and therefore should not require urgent care services. Previous mental health related ambulatory sensitive conditions have included psychotic and mood disorders; however, limited research has explored these relationships of increased hospitalization among specific health disorders with Indigenous populations. This study analyzed predictors of prior mental health hospitalizations among a predominately First Nations population seeking residential treatment for substance use. We hypothesized that increased co-morbid mental health concerns would predict increased hospitalizations for mental health concerns, and this relationship would be moderated by higher Adverse Childhood Experience (ACE) scores. Logistic regression showed that for every increase in each reported mental health concern, the odds of prior hospitalization was 1.6 times higher among this sample, although ACEs did not moderate this relationship. Participants with depressive, anxiety-related, psychotic, and personality-related disorders reported proportionally more hospitalization. Although study results suggest ACEs are not a useful predictor of hospitalization, their presence has previously shown to exacerbate co-morbid concerns, and thus, may influence prior hospitalization history indirectly. Further research can explore relationships between exposure to childhood trauma and hospitalization, particularly in consideration of access to tertiary mental health services.

Authors: Fras Katrina , Bakunda Linda , Crowshoe Lynden , Roach Pamela 
Published: September 2024

Background/Purpose
The study explores the perspectives of family physicians in Alberta regarding Indigenous health research education within the framework of primary health care (PHC). Recognizing the key role of PHC in healthcare system, the research identified the preferences and needs of family physicians for relevant and accessible research skills education. To design effective research education, it is critical to understand the skills, content, and delivery methods desired by family physicians engaged in Indigenous health research. The Indigenous Primary Health Care and Policy Research (IPHCPR) Network is examined as a potential transformative platform aligned with Truth and Reconciliation Commission principles and Calls to Action.
Methods
Through purposive sampling, 12 family physicians practicing in Alberta were recruited to participate in semi-structured qualitative interviews . The study utilized a thematic content approach for data analysis.
Results
Four key themes emerged from the analysis: 1) Indigenous role modeling; 2) cohort-based learning; 3) relational learning; and 4) the epistemic importance of Indigenous perspectives on learning. Participants emphasized the need for mentorship, collaborative learning settings, and meaningful connections within a research network.
Discussion
The IPHCPR Network stands out as a pivotal platform for transformative change in healthcare research education, offering opportunities for family physicians, researchers, trainees, and communities to collaboratively improve Indigenous health outcomes. Through its inclusive practices, the network aligns with TRC principles to advance Indigenous health equity and addressing critical gaps in Indigenous primary health research and practice.

BackgroundThe identification of efficient predictors for short-term mortality among patients with myocardial infarction (MI) in coronary care units (CCU) remains a challenge. This study seeks to investigate the potential of machine learning (ML) to improve risk prediction and develop a predictive model specifically tailored for 30-day mortality in critical MI patients.MethodThis study focused on MI patients extracted from the Medical Information Mart for Intensive Care-IV database. The patient cohort was randomly stratified into derivation (n = 1,389, 70%) and validation (n = 595, 30%) groups. Independent risk factors were identified through eXtreme Gradient Boosting (XGBoost) and random decision forest (RDF) methodologies. Subsequently, multivariate logistic regression analysis was employed to construct predictive models. The discrimination, calibration and clinical utility were assessed utilizing metrics such as receiver operating characteristic (ROC) curve, calibration plot and decision curve analysis (DCA).ResultA total of 1,984 patients were identified (mean [SD] age, 69.4 [13.0] years; 659 [33.2%] female). The predictive performance of the XGBoost and RDF-based models demonstrated similar efficacy. Subsequently, a 30-day mortality prediction algorithm was developed using the same selected variables, and a regression model was visually represented through a nomogram. In the validation group, the nomogram (Area Under the Curve [AUC]: 0.835, 95% Confidence Interval [CI]: [0.774–0.897]) exhibited superior discriminative capability for 30-day mortality compared to the Sequential Organ Failure Assessment (SOFA) score [AUC: 0.735, 95% CI: (0.662–0.809)]. The nomogram (Accuracy: 0.914) and the SOFA score (Accuracy: 0.913) demonstrated satisfactory calibration. DCA indicated that the nomogram outperformed the SOFA score, providing a net benefit in predicting mortality.ConclusionThe ML-based predictive model demonstrated significant efficacy in forecasting 30-day mortality among MI patients admitted to the CCU. The prognostic factors identified were age, blood urea nitrogen, heart rate, pulse oximetry-derived oxygen saturation, bicarbonate, and metoprolol use. This model serves as a valuable decision-making tool for clinicians.
