[DESIGN INDEPENDENCE A COMPLEMENTARY PRINCIPLE IN THE DESIGN OF INTERIOR SPACES OF MALAYSIAN MOSQUE CASE STUDY] الاستقلالية التصميمية مبدأ تكميلي في تصاميم الفضاءات الداخلية للمساجد الماليزية دراسة حالة
The interior design of Malaysian Islamic mosques is a vivid example of further innovation and innovation based on design creativity in design relationships.As a result of the interaction of this level, the design process shows a clear independence as a result of the interaction of the subjective capabilities factor of the interior designer based on the study of the specificity of the objective capabilities that govern the processes of drafting innovative decorative arts.Therefore, it was necessary to study this issue by identifying the research problem, which is summarized by: showing the features of design independence as a complementary principle in the designs of the interior spaces of Malaysian mosques,While the aim of the research focuses on identifying the features of design independence that are adopted as a complementary principle in the designs of the interior spaces of Malaysian mosques,While the importance of research is evident in presenting a clear picture of the concept of design independence, as it represents the theoretical base that can be used in practical application in designs of interior spaces for the chapel of the Malaysian Islamic mosques,The research study also includes both (research limits, theoretical framework, as well as research procedures based on the descriptive analytical approach (content analysis - case study)) leading to the results of the research study, which was among the most important: 1- Design configurations of all kinds and design configurations emerged within the designs of the internal determinants, based on the study of the interior designer, to the aesthetic independence of the division of space and size as a complementary principle within the internal determinants of the mosque of the two mosques. 2- The relationship of the principle of the independence of convergence as a complementary principle contributed to determining the distances between shapes, which can be perceived as a unified whole, through the distribution of units and shapes within a consecutive visual design system. While the most important recommendations emerged through the necessity of studying the choice of levels of internal determinants of the chapel of the Malaysian Islamic mosques.With the demonstration of the expressive characteristic of civilization development through design recruitment of appropriate vocabulary and design units with a careful selection of modern materials and materials in line with the innovative design path to achieve the requirements of design independence within the chapel of the Malaysian Islamic mosques
Development and Validation of R-hf Risk Score in Acute Heart Failure Patients in the Middle East
Objectives: The Rajan’s heart failure (R-hf) score was proposed to aid risk stratification in heart failure patients. The aim of this study was to validate R-hf risk score in patients with acute decompensated heart failure. Methods: R-hf risk score is derived from the product estimated glomerular filtration rate (mL/min), left ventricular ejection fraction (%), and hemoglobin levels (g/dL) divided by N-terminal pro-brain natriuretic peptide (pg/mL). This was a multinational, multicenter, prospective registry of heart failure from seven countries in the Middle East. Univariable and multivariable logistic regression was applied. Results: A total of 776 patients (mean age = 62.0±14.0 years, 62.4% males; mean left ventricular ejection fraction = 33.0±14.0%) were included. Of these, 459 (59.1%) presented with acute decompensated chronic heart failure. The R-hf risk score group (≤ 5) was marginally associated with a higher risk of all-cause cumulative mortality at three months (adjusted odds ratio (aOR) = 4.28; 95% CI: 0.90–20.30; p =0.067) and significantly at 12 months (aOR = 3.84; 95% CI: 1.23–12.00; p =0.021) when compared to those with the highest R score group (≥ 50). Conclusions: Lower R-hf risk scores are associated with increased risk of all-cause cumulative mortality at three and 12 months
Demystifying Smoker's Paradox: A Propensity Score-Weighted Analysis in Patients Hospitalized With Acute Heart Failure.
Background Smoker's paradox has been observed with several vascular disorders, yet there are limited data in patients with acute heart failure (HF). We examined the effects of smoking in patients with acute HF using data from a large multicenter registry. The objective was to determine if the design and analytic approach could explain the smoker's paradox in acute HF mortality. Methods and Results The data were sourced from the acute HF registry (Gulf CARE [Gulf Acute Heart Failure Registry]), a multicenter registry that recruited patients over 10 months admitted with a diagnosis of acute HF from 47 hospitals in 7 Middle Eastern countries. The association between smoking and mortality (in hospital) was examined using covariate adjustment, making use of mortality risk factors. A parallel analysis was performed using covariate balancing through propensity scores. Of 5005 patients hospitalized with acute HF, 1103 (22%) were current smokers. The in-hospital mortality rates were significantly lower in current smoker's before (odds ratio, 0.71; 95% CI, 0.52-0.96) and more so after (odds ratio, 0.47; 95% CI, 0.31-0.70) covariate adjustment. With the propensity score-derived covariate balance, the smoking effect became much less certain (odds ratio, 0.63; 95% CI, 0.36-1.11). Conclusions The current study illustrates the fact that the smoker's paradox is likely to be a result of residual confounding as covariate adjustment may not resolve this if there are many competing prognostic confounders. In this situation, propensity score methods for covariate balancing seem preferable. Clinical Trial Registration URL: https://www.clinicaltrials.gov/.

Predictors of early and late mortality after transcatheter aortic valve implantation : a multicenter retrospective Chinese study
Background: Patients undergoing TAVR constitute a high-risk population given their comorbidities and out-of-hospital mortality rates remain high despite significant improvements in the overall procedural outcomes. Objectives: The objective of this study was to determine the early and late mortality rates following transfemoral transcatheter aortic valve replacement (TAVR) and identify the risk factors for poor outcomes. Methods: This study population examined patients extracted from 43 publicly funded hospitals in Hong Kong between 2010 and 2019. The study constitutes retrospective analysis of mortality outcomes for severe aortic stenosis patients undergoing TAVR. The primary end points include out-of-hospital 30-day, 1-year, 1–2-year, and 2–5-year mortality rates. Results: A total of 448 patients underwent TAVR and were included into the study. The rates of mortality following TAVR were 1.7%, 3.3%, 1.3%, and 0.22% at 30 days, 1, 1–2, and 2–5 years, respectively. Age and chronic renal failure (CRF) were concluded to be associated with postprocedural mortality. Further analysis of the baseline echocardiographic parameters revealed a higher prevalence of right atrial enlargement (RAE) and tricuspid and pulmonary regurgitation in the deceased subgroup. Conclusion: We report the 30-day, 1-, 1–2-, and 2–5-year all-cause mortality for TAVR of 1.7%, 3.3%, 1.3%, and 0.22% at 30 days. Factors associated with a higher prevalence of mortality include age, CRF, RAE, and tricuspid and pulmonary regurgitation
Clinical outcomes of transcatheter aortic valve replacement stratified by left ventricular ejection fraction : a single centre pilot study
Introduction: To define baseline echocardiographic, electrocardiographic (ECG) and computed tomographic (CT) findings of patients with heart failure undergoing transcatheter aortic valve replacement (TAVR) and analyze their overall procedural outcomes. Methods: Between 2018 and 2021, patients with severe aortic stenosis (AS) who performed transcatheter aortic valve replacement (TAVR) in Sabah Al Ahmad Cardiac Centre, Al Amiri Hospital were identified. A retrospective review of patients' parameters including pre-, intra-, and post-procedural data was conducted. Patients were grouped in 2 subgroups according to their EF: EF <40% (HFrEF) and EF ≥ 40%. The data included patients’ baseline characteristics, electrocardiographic and echocardiographic details along with pre-procedural CT assessment of aortic valve dimensions. Primary outcomes including post-operative disturbances, pacemaker implantation and in-hospital mortality following TAVR were additionally analyzed. Results: A total of 61 patients with severe AS underwent TAVR. The mean age was 73.5 ± 9, and 21 (34%) of the patients were males. The mean ejection fraction (EF) was 55.5 ± 9.7%. Of 61 patients, 12 (20%) were identified as heart failure with reduced EF (<40%). These patients were younger, more often males, and were more likely to have coronary artery disease (75% versus 53.1%). Left ventricular hypertrophy and diastolic dysfunction was documented in 75% and 58.3% of patients with heart failure with reduced ejection fraction (HFrEF) respectively. Post TAVR conduction disturbances, with the commonest being LBBB was observed in 41.7%. Permanent pacemaker was implanted in 3 of patients with HFrEF (25%). There were no significant differences between the two groups with regards to in hospital mortality (p = 0.618). Conclusion: Severe AS with EF <40% constitute a remarkable proportion of patients undergoing TAVR. Preliminary results of post-operative conduction disturbances and in hospital mortality in HFrEF patients were concluded to not differ from patients with LVEF ≥40%
In-hospital mortality in SARS-CoV-2 stratified by hemoglobin levels : a retrospective study
This study is to estimate in-hospital mortality in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients stratified by hemoglobin (Hb) level. Patients were stratified according to hemoglobin level into two groups, that is, Hb 100 g/L. A total of 6931 patients were included. Of these, 6377 (92%) patients had hemoglobin levels >100 g/L. The mean age was 44 ± 17 years, and 66% of the patients were males. The median length of overall hospital stay was 13 days [2; 31]. The remaining 554 (8%) patients had a hemoglobin level 100 g/L (52, 0.82%). Risk factors associated with increased mortality were determined by multi- variate analysis. The Kaplan-Meier survival analysis showed hemoglobin as a predictor of mortality. Cox proportional hazards regression coefficients for hemoglobin for the HB ≤ 100 category of hemoglobin were significant, B = 2.79, SE = 0.17, and HR = 16.34, p < 0.001. Multivariate logistic regression showed Hb < 100 g/L had a higher cumu- lative all-cause in-hospital mortality (22.4% vs. 0.8%; adjusted odds ratio [aOR], 0.33; 95% [CI]: [0.20–0.55]; p < 0.001). In this study, hemoglobin levels <100 g/L were found to be an independent predictor of in-hospital mortality
