Background: Pleurodesis fails in 10%-40% of patients with recurrent malignant pleural effusions malignant pleural effusion and dyspnea. This study aimed to assess the values of pleural elastance (P_EL) after the aspiration of 500 mL of pleural fluid and their relation to the pleurodesis outcome, and to compare the pleurodesis outcome with the chemical characteristics of pleural fluid. Methods: A prospective study was conducted in Kasr El-Aini Hospital, Cairo University, during the period from March 2019 to January 2020. The study population consisted of 40 patients with malignant pleural effusion. The measurement of PEL after the aspiration of 500 mL of fluid was done with “P_EL 0.5” (cm H₂O/L), and the characteristics of the pleural fluid were chemically and cytologically analyzed. Pleurodesis was done and the patients were evaluated one month later. The PEL values were compared with pleurodesis outcomes. Results: After 4-week of follow-up, the success rate of pleurodesis was 65%. The P_EL 0.5 was significantly higher in failed pleurodesis than it was in successful pleurodesis. A cutoff point of P_EL 0.5 >14.5 cm H₂O/L was associated with pleurodesis failure with a sensitivity and specificity of 93% and 100%, respectively. The patients with failed pleurodesis had significantly lower pH levels in fluid than those in the successful group (p<0.001). Conclusion: PEL measurement was a significant predictor in differentiating between failed and successful pleurodesis. The increase in acidity of the malignant pleural fluid can be used as a predictor for pleurodesis failure in patients with malignant pleural effusion.

The kinetics of cell growth and Cyclosporin A (Cyc A) production by Tolypocladium inflatum were studied in shake flasks and bioreactors under controlled and uncontrolled pH conditions. In the case of the shake flask, the production time was extended to 226 h and the maximal antibiotic concentration was 76 mg/l. When scaling up the cultivation process to a bioreactor level, the production time was reduced to only 70 h with a significant increase in both the cell growth and the antibiotic production. The maximal dry cell weights in the case of the controlled pH and uncontrolled pH cultures in the bioreactor were 22.4 g/l and 14.2 g/l, respectively. The corresponding maximal dry cell weight values did not exceed 7.25 g/l with the shake flask cultures. The maximal values for Cyc A production were 144.72 and 131.4 mg/l for the controlled and uncontrolled pH cultures, respectively. It is also worth noting that a significant reduction was observed in both the dry cell mass and the antibiotic concentration after the Cyc A production phase, whereas the highest rate of antibiotic degradation was observed in the stirred tank bioreactor with an uncontrolled pH. Morphological characterization of the micromorphological cell growth (mycelial/pellet forms) was also performed during cultivation in the bioreactor.

Evidence of the association between 25-hydroxyvitamin D (25(OH)D) and metabolic syndrome (MeS) remains uncertain and incongruent. This study aimed to determine the association between 25(OH)D and MeS among Jordanian adults. A complex multistage sampling technique was used to select a national population-based household sample. The present report deals exclusively with adults aged > 18 years who had complete information on all components of MeS (n = 3,234). A structured questionnaire was used to collect all relevant information. Anthropometric, clinical, and laboratory measurements were obtained. MeS was defined according to the International Diabetes Federation (IDF) definition. Of the total, 42.0% had MeS and 31.7% had 25(OH)D < 30 ng/ml. In a stratified analysis, the prevalence of MeS did not differ significantly between subjects with low and normal 25(OH)D levels for men and women in all age groups. In the multivariate analysis, the odds of MeS were not significantly different between subjects with low and normal 25(OH)D levels (OR = 0.85, 95% CI: 0.70, 1.05, P-value = 0.133). The association between 25(OH)D and MeS remained non-significant when 25(OH)D was analyzed as a continuous variable (OR = 1.004, 95% CI; 1.000, 1.008, P = 0.057) and when analyzed based on quartiles. None of the individual components of MeS were significantly associated with 25(OH)D level. This study does not provide evidence to support the association between 25(OH)D level and MeS or its individual components. Prospective studies are necessary to better determine the roles of 25(OH)D levels in the etiology of MeS.

Flexible Smart Home Architecture using Device Profile for Web Services: a Peer-to-Peer Approach

Jorge Parra,M. Anwar Hossain,Abdulmotaleb El Saddik,Aitor Uribarren,Eduardo Jacob 보안공학연구지원센터 2009 International Journal of Smart Home Vol.3 No.2

In this paper we propose the design and development of a flexible smart home architecture using a peer-to-peer (P2P) approach. We specifically focus on two distinct aspects of this proposed architecture. First, we analyze how the different home devices and services can be represented as individual peers in order to have a decentralized system, which is scalable by nature and avoids the single point-of-failure usually attributed to a centralized server. Second, we investigate the distribution of application workflow logic among the peers to develop a flexible home architecture with autonomous behavior of the peers. We analyze the suitability of Devices Profile for Web Services (DPWS) to realize the proposed P2P-like architecture for the smart home. We further show how to distribute the application workflow logic among the peers and yet achieving the same global behavior of the system. Our experimental results show that DPWS provides tools and techniques, in particular its discovery and eventing mechanism, which can be leveraged to provide flexibility and autonomy in the overall architecture.

Introduction: The risk of experiencing psychiatric symptoms related to the COVID-19 pandemic is high among healthcare workers whose occupations are in public health, emergency medicine, and intensive or critical care. Materials and methods: A cross-sectional study aimed to assess the prevalence of fear of COVID-19 among 411 frontline Egyptian physicians during the COVID-19 pandemic; identify determinants and predictors for fear of COVID-19; determine the impact of fear of COVID-19 on job satisfaction; and detect the impact of fear of COVID-19 on turnover intention. Three standardized scales (fear of COVID-19, job satisfaction, and turnover intention scores) were used for data collection via online Google Form. Results: Regarding fear relating to the COVID-19 pandemic, 16.5% of the study subjects were classified as experiencing a severe fear level, while 78.1% experienced a moderate degree. A significant association between the level of fear relating to COVID-19 and the work department. The highest degree of fear is in a general-educational-university facility. Regarding job satisfaction, 42% of those having a severe level of fear are dissatisfied. Fear of COVID-19 is negatively associated with job satisfaction while positively significant correlated with turnover scores, a positive significant predictor of turnover intention. Job satisfaction is negatively associated with turnover intention; a negative significant predictor of turnover intention. Conclusions: Frontline Egyptian physicians reported higher levels of fear relating to the COVID-19 pandemic (moderate to severe). Increased fear levels relating to COVID-19 have a relationship with lower levels of job satisfaction and higher levels of job turnover.

OBJECTIVES: The aim of this study was to determine the prevalence of obesity in Jordan, to assess related trends, and to determine associated factors and comorbidities. METHODS: A multipurpose national household survey of Jordanian adults was conducted over a 4-month period in 2017. Data were collected using a structured validated questionnaire. Anthropometric measurements including waist circumference (WC; measured midway between the iliac crest and the lower rib margin), body mass index (BMI), hip circumference, waist-to-hip ratio, and waist-to-height ratio were obtained to categorize participants with regard to overweight and obesity. RESULTS: This study included 4,056 persons (1,193 men and 2,863 women) aged 18 years to 90 years (mean±standard deviation, 43.8±14.2 years). According to the International Diabetes Federation WC criteria, the age-standardized prevalence of obesity was 60.4% among men and 75.6% among women, while approximately three-quarters of men and women were overweight or obese as defined by BMI. The age-adjusted odds of obesity in 2017 were approximately twice those in 2009 in men (odds ratio [OR], 1.98) and women (OR, 1.96). In the multivariate analysis, age, region of residence, and marital status were significantly associated with obesity in both genders. Obesity was significantly associated with increased odds of diabetes mellitus, hypertension, elevated triglycerides, and low high-density lipoprotein cholesterol after adjusting for age. CONCLUSIONS: The rate of obesity in Jordan is high and increasing, and obesity is associated with other metabolic abnormalities. Well-defined programs to control and prevent obesity, as well as intersectoral action, are urgently required to reverse current trends.

Ahmed Mohamed Sharaf,Eslam Syala,Abbas Anwar Ezzat,Salah F. Abdellah Ali,E. El-Rafey 한국섬유공학회 2022 Fibers and polymers Vol.23 No.5

Both the chicken eggshell (ES) and rice husk (RH) represent environmental, and pollution issues. Incorporatingboth of them, with minimum processing procedures, in various useful applications is a major contribution in solving suchproblems. In this research, unsaturated polyester (UP) was doped with different percentages (5-25 wt.%) of fine (ES) to formone (UP-ES) composite system. The (UP-ES) system was reinforced with a fixed 10 wt.% of (RH), which represents anagricultural waste produced in tonnage, to fabricate the second system. X-ray diffraction (XRD) analysis emerged that the(ES) is forming from calcium carbonate (CaCO3) resembling typically the mineral one. The addition of (ES) enhanced boththe mechanical characteristics of (UP) resin in terms of tensile strength, elongation %, tensile modulus, impact strength,flexural strength from 26.33 to 33.77 MPa, from 3.30 to 3.60 MPa, from 2000 to 2406.67 MPa, from 1.25 to 2.42 kJ/m², from64.93 to 75.07 MPa, and the thermal stability from 335.75 to 346.24 oC, respectively. This inclusion of (ES) also promotedboth the limiting oxygen index (LOI) and dielectric constant (εr) of (UP) from 17.25 to 23.50 % and from 6.76 to 11.02,respectively. The addition of (RH) to (ES-UP) composite, generally, gave the same attitude for the properties like what in the(ES-UP) system other than the remarkable extra-increase in the (εr). Also, (RH) elevated the water absorption (%) of (ES-UP)composite by the action of its hydrophilic nature. It is concluded that the incorporation of both (ES) and (RH) reduces thefinal cost of the composite and solves one of the great environmental disposal issues.

Objectives. Carbon dioxide (CO2) laser cordectomy is considered one of the modalities of choice for treatment of early glottic carcinoma. In addition to its comparable oncological results with radiotherapy and open surgical procedures, it preserves of laryngeal functions including voice production. The aim of this study was to detect how the larynx compensates for voice production after different types of CO2 laser cordectomy for early glottic carcinoma together with assessment of the vocal outcome in each compensation mechanism. Methods. One hundred twelve patients treated with CO2 laser cordectomy were classified according to their main postoperative phonatory site. Perceptual analysis of voice samples using GRBAS (grade, roughness, breathiness, asthenia, and strain) scale was done for 88 patients after exclusion of the voice samples of all female patients to make the study population homogenous and the samples of 18 male patients due to bad quality (4 patients) or unavailability (14 patients) of their voice samples and the results were compared with those obtained from control group that included 25 age-matched euphonic male subjects. Results. Five types of laryngeal compensation were defined including: vocal fold to vocal fold, vocal fold to vocal neofold, vocal fold to vestibular fold, vestibular fold, to vestibular fold, and arytenoids hyper adduction. Characters changes of voice produced by each compensation type were found to be statistically significant except for breathiness, asthenia and strain changes in vocal fold to vocal fold compensation type. Conclusion. The larynx can compensate for voice production after CO2 laser cordectomy by five different compensation mechanisms with none of them producing voice quality comparable with that of controls.
