An Evaluation of Prediction Equations for the 6 Minute Walk Test in Healthy European Adults Aged 50-85 Years

This study compared actual 6 minute walk test (6MWT) performance with predicted 6MWT using previously validated equations and then determined whether allometric modelling offers a sounder alternative to estimating 6MWT in adults aged 50-80 years.We compared actual 6MWT performance against predicted 6MWT in 125 adults aged 50-85 years (62 male, 63 female). In a second sample of 246 adults aged 50-85 years (74 male, 172 female), a new prediction equation for 6MWT performance was developed using allometric modelling. This equation was then cross validated using the same sample that the other prediction equations were compared with.Significant relationships were evident between 6MWT actual and 6MWT predicted using all of the commonly available prediction equations (all P<0.05 or better) with the exception of the Alameri et al prediction equation (P>0.05). A series of paired t-tests indicated significant differences between 6MWT actual and 6MWT predicted for all available prediction equations (all P<0.05 or better) with the exception of the Iwama et al equation (P = .540). The Iwama et al equation also had similar bias (79.8m) and a coefficient of variation of over 15%. Using sample 2, a log-linear model significantly predicted 6MWT from the log of body mass and height and age (P = 0.001, adjusted R2 = .526), predicting 52.6% of the variance in actual 6MWT. When this allometric equation was applied to the original sample, the relationship between 6MWT actual and 6MWT predicted was in excess of values reported for the other previously validated prediction equations (r = .706, P = 0.001). There was a significant difference between actual 6MWT and 6MWT predicted using this new equation (P = 0.001) but the bias, standard deviation of differences and coefficient of variation were all less than for the other equations.Where actual assessment of the 6MWT is not possible, the allometrically derived equation presented in the current study, offers a viable alternative which has been cross validated and has the least SD of differences and smallest coefficient of variation compared to any of the previously validated equations for the 6MWT

High prevalence of cardiometabolic risk factors amongst young adults in the United Arab Emirates: the UAE Healthy Future Study

BackgroundCardiovascular disease (CVD) is the leading cause of death in the world. In the United Arab Emirates (UAE), it accounts for 40% of mortality. CVD is caused by multiple cardiometabolic risk factors (CRFs) including obesity, dysglycemia, dyslipidemia, hypertension and central obesity. However, there are limited studies focusing on the CVD risk burden among young Emirati adults. This study investigates the burden of CRFs in a sample of young Emiratis, and estimates the distribution in relation to sociodemographic and behavioral determinants.MethodsData was used from the baseline data of the UAE Healthy Future Study volunteers. The study participants were aged 18 to 40 years. The study analysis was based on self-reported questionnaires, anthropometric and blood pressure measurements, as well as blood analysis.ResultsA total of 5167 participants were included in the analysis; 62% were males and the mean age of the sample was 25.7 years. The age-adjusted prevalence was 26.5% for obesity, 11.7% for dysglycemia, 62.7% for dyslipidemia, 22.4% for hypertension and 22.5% for central obesity. The CRFs were distributed differently when compared within social and behavioral groups. For example, obesity, dyslipidemia and central obesity in men were found higher among smokers than non-smokers (p \u3c 0.05). And among women with lower education, all CRFs were reported significantly higher than those with higher education, except for hypertension. Most CRFs were significantly higher among men and women with positive family history of common non-communicable diseases.ConclusionsCRFs are highly prevalent in the young Emirati adults of the UAE Healthy Future Study. The difference in CRF distribution among social and behavioral groups can be taken into account to target group-specific prevention measures

The interrelationship and accumulation of cardiometabolic risk factors amongst young adults in the United Arab Emirates: The UAE Healthy Future Study.

INTRODUCTION: Similar to other non-communicable diseases (NCDs), people who develop cardiovascular disease (CVD) typically have more than one risk factor. The clustering of cardiovascular risk factors begins in youth, early adulthood, and middle age. The presence of multiple risk factors simultaneously has been shown to increase the risk for atherosclerosis development in young and middle-aged adults and risk of CVD in middle age. OBJECTIVE: This study aimed to address the interrelationship of CVD risk factors and their accumulation in a large sample of young adults in the United Arab Emirates (UAE). METHODS: Baseline data was drawn from the UAE Healthy Future Study (UAEHFS), a volunteer-based multicenter study that recruits Emirati nationals. Data of participants aged 18 to 40 years was used for cross-sectional analysis. Demographic and health information was collected through self-reported questionnaires. Anthropometric data and blood pressure were measured, and blood samples were collected. RESULTS: A total of 5126 participants were included in the analysis. Comorbidity analyses showed that dyslipidemia and obesity co-existed with other cardiometabolic risk factors (CRFs) more than 70% and 50% of the time, respectively. Multivariate logistic regression analysis of the risk factors with age and gender showed that all risk factors were highly associated with each other. The strongest relationship was found with obesity; it was associated with four-fold increase in the odds of having central obesity [adjusted OR 4.70 (95% CI (4.04-5.46)], and almost three-fold increase odds of having abnormal glycemic status [AOR 2.98 (95% (CI 2.49-3.55))], hypertension (AOR 3.03 (95% CI (2.61-3.52))] and dyslipidemia [AOR 2.71 (95% CI (2.32-3.15)]. Forty percent of the population accumulated more than 2 risk factors, and the burden increased with age. CONCLUSION: In this young population, cardiometabolic risk factors are highly prevalent and are associated with each other, therefore creating a heavy burden of risk factors. This forecasts an increase in the burden of CVD in the UAE. The robust longitudinal design of the UAEHFS will enable researchers to understand how risk factors cluster before disease develops. This knowledge will offer a novel approach to design group-specific preventive measures for CVD development

Marine turtles: a comprehensive review and an assessment of climate change-associated impacts in Abu Dhabi, United Arab Emirates

Climate change threatens marine turtles that depend on beaches for nesting with temperature changes affecting embryonic development and sex determination. Sea level rise may destroy their nesting habitats, and warming temperatures may cause complete development failure and imbalanced sex ratios. It is critical, therefore, to understand the likely climate change impacts to ensure mitigation is undertaken. It is particularly useful to examine climate change impacts in areas already facing extreme environmental conditions. The northwestern Indian Ocean (NWIO) is a relatively understudied region regarding marine turtles. Key knowledge gaps helped shape the main aims of this thesis, and these are: 1. to understand the status of marine turtles in the NWIO region from published material and regional expert elicitation; 2. to analyze 20 years of available data on marine turtles in Abu Dhabi, United Arab Emirates; 3. to investigate nest temperatures in Abu Dhabi to estimate primary sex ratios and the likely impact of global climate change on population dynamics and conservation, and; 4. to estimate the level of nest inundation that might result from forecast sea level rises associated with climate change. My key findings were that: 1. Significant research and conservation efforts have focused on marine turtles across the NWIO region. I identified major threats, knowledge gaps, impediments to practical conservation, and strengths and opportunities towards creating a knowledge base for future research. 6 2. The long-term marine turtle conservation plan in Abu Dhabi Emirate covers nesting ecology, foraging, mortality investigations, and rehabilitation initiatives. The mean estimate of hawksbill turtle clutches per year was 220 while the foraging population of all species and all sizes found in the emirate is 5,550–7,488 individuals. The majority of mortality was due to drowning in abandoned nets. Further research, including additional in-water foraging studies, population structure, and comprehensive nesting trends, is vital. 3. Primary sex ratios of hawksbill hatchlings are prone to be highly female-biased (> 80 % female), and only nests in the first three weeks of the breeding season were likely to have produced male hatchlings. 4. Beaches at major nesting islands will be profoundly affected by inundation due to sea level rise, however, the core nesting areas will remain as potential nesting sites. I propose additional management approaches under each aspect and a detailed list of research priorities for Abu Dhab

A mechanistic investigation of cell breakup in tomato juice homogenization

High-pressure homogenizers are often used in tomato juice production to fragment tomato cells, to increase viscosity. Compared to emulsification, little is known about the mechanism of cell breakup in general and of vegetable cell breakup in particular. The objective of this contribution is to extend the mechanistic understanding of vegetable cell breakup in homogenizers, using a research methodology previously proven fruitful for emulsification. Four mechanistic suggestions for cell breakup are identified in the emulsification and cell breakup literature (turbulent inertial, turbulent viscous, laminar shear and physical interactions). Theoretical expressions predicting how cell fragment size should scale with homogenizing pressure, serum viscosity and flowrate are derived and compared to experiments. It is concluded that none of these commonly suggested mechanisms (or combinations thereof) comply with the data, suggesting that an altogether different mechanism controls cell breakup in homogenizers. Results are used to compare drop and cell breakup in homogenizers

Effect of Processing Parameters on Wear Properties of Hybrid AA1050/Al₂O₃/TiO₂ Composites

In this study, hybrid AA1050/Al2O3/TiO2 composites have been produced via combined liquid casting and powder metallurgy techniques. Degassing was utilized to improve the wettability of molten aluminum alloys, and then successful bonding was generated between aluminum matrix and reinforcement particles during the powder metallurgy technique. As the base matrix and reinforcements, AA1050 alloy, Al2O3 and TiO2 particles were taken, respectively. Then, content values of 5Wt.% of Al2O3 in the mesh size of 20 μm and 2.5 and 5 wt. % of TiO2 particles with mesh size of 5μm were added to the AA1050 matrix. For each composite sample, ceramic particles were warmed to 600°C in order to improve wettability and distribution. An identical scattering of subdivisions was observed through aluminum (as matrix) in the microstructural study. To measure the wear resistance, the mechanism of rotary wear test was used. The achieved results illustrated that the fabrication of hybrid composites is an ideal approach to improve the wear resistance of Al-based composites. By increasing of TiO2 Wt.% up to 5% for all composite samples, the wear rate improved to less than half of the monolithic Al alloy value for each composite sample
