Oro-Dental Health Status and Salivary Characteristics in Children with Chronic Renal Failure

Children suffering from decreased renal function may demand unique considerations regarding special oral and dental conditions they are encountered to. It is mentioned that renal function deterioration may affect the hard or soft tissues of the mouth. Having knowledge about the high prevalence of dental defects, calculus, gingival hyperplasia, modified salivary composition and tissue responses to the dental plaque may aid the physician and the dentist to help nurture the patient with chronic renal failure through the crisis, with an aesthetically satisfying and functioning dentition

Leaf Area, Fresh Weight and Dry Weight Prediction Models for Ornamental Plants Ficus benjamina (cv. Starlight)

Measurements of leaf growth indices namely leaf area, fresh weight and dry weight are of value in physiological studies and plant growth estimation. The use of prediction models to estimate leaf area, fresh weight and dry weight is simple, rapid and non-destructive. Several mathematical functions have been formulated for estimating leaf area, fresh weight and dry weight of various crops but almost there is no information for Ficus benjamina. This work was aimed to propose leaf area (LA), fresh weight (FW) and dry weight (DW) prediction models for Ficus benjamina (cv. Starlight) leafy ornamental pot plant using leaf length (L) and width (W). 1000 leaves were collected randomly from greenhouse grown plants and 700 of cuts were used for prediction models. LA was measured with a digital area meter (DELTA-T, Co. Durham, UK), related FW and DW also were weighted and leaf dimensions were determined by the ruler. For each studying growth index LA, FW and DW the predictive abilities of three regression equations (linear, polynomial and power) were compared with different independent variables for each equation. Leaf length × width provided a good estimation of leaf area and fresh weight of the leaves of Ficus benjamina. It was also concluded that leaves the dry weight of Ficus benjamina can be estimated or simulated as a power function of L×W or L+W with reasonable accuracy. Moreover, a reasonable relationship between leaf fresh weight and leaf area was found too

TCT-121 Extraplaque Versus Intraplaque Tracking in Chronic Total Occlusion Percutaneous Coronary Intervention

Background: The impact of modern extraplaque (EP) tracking techniques on long-term outcomes remains controversial. Methods: We performed a systematic review and meta-analysis of studies that compared EP vs intraplaque (IP) tracking in CTO PCI. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the Der-Simonian and Laird random-effects method. Results: Our meta-analysis included seven observational studies with 2,982 patients. Patients who underwent EP tracking had significantly more complex CTOs with higher J-CTO scores (2.9 ± 1.2 vs 1.6 ± 1.1, P \u3c 0.001), longer lesion length, more severe calcification, and significantly longer stented segments. During a median follow-up of 12 months (range 9-12 months), EP tracking was associated with a higher risk of major adverse cardiovascular events (MACE) (OR 1.50, 95% CI 1.10-2.06, P = 0.01) and target vessel revascularization (TVR) (OR 1.69, 95% CI 1.15-2.48, P = 0.01) compared with IP tracking. There was no difference in the incidence of all-cause death (OR 1.37, 95% CI 0.67-2.78, P = 0.39), myocardial infarction (MI) (OR 1.48, 95% CI 0.82-2.69, P = 0.20), or stent thrombosis (OR 2.09, 95% CI 0.69-6.33, P = 0.19) between EP and IP tracking. Conclusion: Compared with IP tracking, EP tracking was utilized in more complex and longer CTOs, required more stents, and was associated with a higher risk of MACE at 12 months, driven by a higher risk of TVR, but without an increased risk of death or MI.

Integration of Arbuscular Mycorrhizal Fungi to Grape Vine (Vitis vinifera L.) in Nursery Stage

The Arbuscular Mycorrhizal (AM) association is being considered as the commonest Mycorrhizal type involved in grape community. Low population density of these useful fungi in vineyard soil suggests the need for manual inoculation of grapevine plantlets at the nursery stage. The influence of three commercial Arbuscular Mycorrhizal fungi strains (Glomus intraradious, G. mosseae, G. fasciculatus and a mixture of them) on growth and biochemical status of four grapevine varieties (Shahroodi, Asgari, Keshmeshi and Khalili) was investigated under greenhouse conditions. Rooted plantlets derived from hardwood cuttings were transplanted in pots containing leaf mold and sand (1:1) followed by inoculation with different fungal inoculums. Various physiological and biochemical parameters were measured at 30 days intervals. The percentage of root colonization was found to be slightly different amongst inoculated vines but it was found to be significantly different with non-inoculated, control plants. Most growth related parameters (vine length, shoot length and leaf area) were enhanced following Mycorrhization but root length and number of leaves were not significantly affected by any fungal intervention. Treated plants typically showed more obvious modifications in their biochemical status. The chlorophyll content (especially "b" and total), total root and shoot phenols were raised in treated plants. The chlorophyll "a" and total soluble sugars were not statistically different in inoculated and control plants. The overall results of the present study suggest that AM fungi can be manually applied, as an easy and economical approach during nursery production, to boost the physiological and biochemical status of the treated plants and production of high quality healthy plantlets

TCT-126 Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention of the Left Anterior Descending Artery

Background: Improvement of left ventricular ejection fraction (LVEF) after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been modest in prior studies. Methods: Our cohort included patients who underwent LAD CTO PCI at a single center (Henry Ford Hospital) from 2014 to 2021. We evaluate the change in LVEF after LAD CTO PCI using the paired t test in all patients, those with ischemic cardiomyopathy (CM), and those who underwent a viability test. Results: From December 2014 to February 2022, a total of 237 LAD CTO PCI procedures were performed at Henry Ford Hospital (proximal LAD: 56.6%). In-hospital MACE occurred in 13 patients (5.5%; death: 1.3%). Landmark analysis after discharge showed an overall survival of the cohort was 92.7% and MACE-free survival of 85.0% over a median follow-up of 2 years. The median baseline EF was 50% (IQR 35%-55%). Only 51 patients had reduced baseline LVEF (40% or less). After a median follow-up of 9.2 months (IQR 3-28.6 months), there was a significant improvement in LVEF after LAD CTO PCI (mean 10.9%, 95% CI 7.1%-14.8%, P \u3c 0.001). When limiting the analysis to patients who had ischemic cardiomyopathy, proximal LAD CTO PCI, and were on optimal medical therapy (n = 29), LVEF was significantly improved (mean increase of 14%, 95% CI 9.5-18.5%, P \u3c 0.001) after a median follow-up period of 6.2 months (3-29.5 months). Conclusion: LAD CTO PCI was associated with a significant 10% improvement in LVEF in ICM patients and was more pronounced (14% improvement) in those who had proximal LAD treated and were on optimal medical therapy.

Persistence of earnings and prediction of future cash flows: the role of timely recognition of bad news

Timely recognition of losses and expenses compared to revenues and increased values precipitates future expenses to match with current revenues. Thus, timely recognition of losses acts to reduce the persistence of earnings. However, it is expected that a more timely recognition of negative cash flows, as bad news, increase the power of earnings for predicting future cash flows. This study investigates the effects of the timely recognition of bad news (loss) versus the good news on the decrease of the persistence of earnings, and the effect of negative cash flows on forecasting future cash flows. In this study, two pooling type models and a panel type model have been used to estimate the persistence of earnings and cash flows. Seventy eight firms that were listed in the Tehran Stock Exchange during the period 2003–2010 were duly reviewed. The results of this research proved that the timely recognition of loss does not affect the persistence and the power of earnings for the purpose of forecasting future cash flows. The findings imply that conservatism does not distort persistence of earnings

A System Dynamics Approach for Hospital Waste Management in a City in a Developing Country: The Case of Nablus, Palestine

Hospitals and health centers provide a variety of healthcare services and normally generate hazardous waste as well as general waste. General waste has a similar nature to that of municipal solid waste and therefore could be disposed of in municipal landfills. However, hazardous waste poses risks to public health, unless it is properly managed. The hospital waste management system encompasses many factors, i.e., number of beds, number of employees, level of service, population, birth rate, fertility rate, and not in my back yard (NIMBY) syndrome. Therefore, this management system requires a comprehensive analysis to determine the role of each factor and its influence on the whole system. In this research, a hospital waste management simulation model is presented based on the system dynamics technique to determine the interaction among these factors in the system using a software package, ithink. This model is used to estimate waste segregation as this is important in the hospital waste management system to minimize risk to public health. Real data has been obtained from a case study of the city of Nablus, Palestine to validate the model. The model exhibits wastes generated from three types of hospitals (private, charitable, and government) by considering the number of both inpatients and outpatients depending on the population of the city under study. The model also offers the facility to compare the total waste generated among these different types of hospitals and anticipate and predict the future generated waste both infectious and non-infectious and the treatment cost incurred
