    The integrity of coatings used in hot section components of combustion turbines is crucial to the reliability of the buckets. This project was initiated in recognition of the need for predicting the life of coatings analytically, and non-destructively; correspondingly, four principal tasks were established. Task 1, with the objective of analytically developing stress, strain and temperature distributions in the bucket and thereby predicting thermal fatigue (TMF) damage for various operating conditions; Task 2 with the objective of developing eddy current techniques to measure both TMF damage and general degradation of coatings and, Task 3 with the objective of developing mechanism based algorithms. Task 4 is aimed at verifying analytical predictions from Task 1 and the NDE predictions from Task 3 against field observations.

    MCrAlY coatings are widely used on hot section components of gas turbines to provide hot corrosion and/or oxidation protection by formation of an oxide layer on the surface. As the protective oxide scale exfoliates during service, aluminum from the coating diffuses outward for reformation of the protective scale. Aluminum may also diffuse inward due to the differences in composition between the coating and the substrate. Thus, the coatings degrade due to oxidation, oxide scale spallation, and inward and outward diffusion of aluminum. Service life of these coatings is controlled by the aluminum content in the coating, operating temperature and start- shutdown cycles. In-service degradation of CoCrAlY and CoNiCrAlY coatings is presented. A procedure to predict the remaining service life of coatings under oxidizing conditions is discussed. (orig.) 12 refs.

    MesoCoat Inc., of Euclid, Ohio, collaborated with Glenn Research Center to provide thermal barrier coating (TBC) technology, developed by Glenn researcher Dongming Zhu, to enhance the lifespan and performance of engines in U.S. Air Force legacy aircraft. The TBC reduces thermal stresses on engine parts, increasing component life by 50 percent. MesoCoat is also producing metal cladding technology that may soon provide similar life-lengthening benefits for the Nation's infrastructure. Through a Space Act Agreement with Glenn, the company employs the Center's high-density infrared arc lamp system to bond its cladding materials for demonstration prototypes; the coating technology can prevent corrosion on metal beams, pipes, and rebar for up to 100 years.

    1984-01-01

    A study of the effect of plasma spray processing parameters on the life of a two layer thermal barrier coating was conducted. The ceramic layer was plasma sprayed at plasma arc currents of 900 and 600 amps onto uncooled tubes, cooled tubes, and solid bars of Waspalloy in a lathe with 1 or 8 passes of the plasma gun. These processing changes affected the residual stress state of the coating. When the specimens were tested in a Mach 0.3 cyclic burner rig at 1130 deg C, a wide range of coating lives resulted. Processing factors which reduced the residual stress state in the coating, such as reduced plasma temperature and increased heat dissipation, significantly increased coating life.

    Inspired by nature, in particular by the marine mussels adhesive proteins (MAPs) and by the tough brick-and-mortar nacre-like structure, novel multilayered films are prepared in the present work. Organic-inorganic multilayered films, with an architecture similar to nacre based on bioactive glass nanoparticles (BG), chitosan, and hyaluronic acid modified with catechol groups, which are the main components responsible for the outstanding adhesion in MAPs, are developed for the first time. The biomimetic conjugate is prepared by carbodiimide chemistry and analyzed by ultraviolet-visible spectrophotometry. The buildup of the multilayered films is monitored with a quartz crystal microbalance with dissipation monitoring, and their topography is characterized by atomic force microscopy. The mechanical properties reveal that the films containing catechol groups and BG present an enhanced adhesion. Moreover, the bioactivity of the films upon immersion in a simulated body fluid solution is evaluated by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. It was found that the constructed films promote the formation of bonelike apatite in vitro. Such multifunctional mussel inspired LbL films, which combine enhanced adhesion and bioactivity, could be potentially used as coatings of a variety of implants for orthopedic applications.

    Thermal barrier coatings applied to the heated side of engine components such as seals, combustor, and blades of a gas turbine offer a potential increase in efficiency through the use of higher gas temperatures or less cooling air or benefits arising from extended component life by reducing component metal temperatures. The considered investigation has the objective to show that while a thermal barrier coated (TBC) specimen can be brought to a fixed temperature using various fuel-air ratio (F/A) values, lower calculated stresses are associated with lower (F/A) values. This implies that control of (F/A) values (i.e., rates of heat input) during the starting transient and to a lesser extent during shutdown and operation, offers a potential method of improving TBC lifetime through thermal cycle management.

    1974-01-01

    The effects of an aluminide coating, Codep B-1, and of section thickness were investigated on two cast nickel base superalloys, Rene 80 and Rene 120. Cast section thicknesses ranged from 0.038 cm to 0.15 cm. Simulated engine exposures for 1000 hours at 899C or 982C in a jet fuel burner rig with cyclic air cooling were studied, as were the effects of surface machining before coating and re-machining and re-coating after exposures. The properties evaluated included tensile at room temperature., 871C and 982C, stress rupture at 760C, 871C, 982C and 1093C, high cycle mechanical fatigue at room temperature., and thermal fatigue with a 1093C peak temperature. Thin sections had tensile strengths similar to standard size bars up to 871C and lower strengths at 982C and above, with equivalent elongation, and stress rupture life was lower for thin sections at all test conditions. The aluminide coating lowered tensile and rupture strengths up to 871C, with greater effects on thinner specimens. Elevated temperature exposure lowered tensile and rupture strengths of thinner specimens at the lower test temperatures. Surface machining had little effect on properties, but re-machining after exposure reduced thickness and increased metallurgical changes enough to lower properties at most test conditions.

    Full Text Available The objective of this study is to determine the incidence of microbial contamination on medical students’ white coats, the way they handle and clean their white coats and their perception towards contamination. For this purpose, cross sectional survey of the bacterial contamination of white coats in a medical college has been carried out in 3 different locations; Royal College of Medicine, Perak, University of Kuala Lumpur and a private college attached to Ipoh General Hospital. It was found that the incidence of Staphylococus aureus, was 32% on short-sleeved and 54% on long-sleeved white coats. Bacillus species was the second most common type of bacteria found. Male collars and female pockets had higher microbial contaminations (p=0.01, 0.03 respectively. Clinical students’ white coats were significantly less contaminated than non-clinical students (p=0.001 although they tend to wear it for a longer period (5.75 ± 2.19 h vs. 2.32 ± 0.81 h (p=0.001. Clinical students owned more short-sleeved coats (p=0.001 and washed their coats more often (p=0.01 than non-clinical ones. More than eighty one percent of clinical students wear their white coats in the college the majority of whom were females (p=0.005. Perception of clinical and non-clinical students towards white coat contamination was similar. Medical students’ white coats are contaminated with bacteria and they are potentially source of cross infection. Student’s way of handling and washing white coats should be corrected by issuing and following standard guidelines. Students should be bared from wearing white coats in non-clinical areas. Washing hands and using plastic aprons is highly recommended before examining wounds.

    Improving the esthetics of Ti-based dental implants is the last challenge remaining in the optimization process. The optical issues were recently solved by the application of highly and selectively reflective coatings on Ti implants. This work focuses on the mechanical durability of these esthetic ceramic based coating systems (with and without adhesion layers). The coating systems (Ti-ZrO2, Ti-Al-ZrO2, Ti-Ti-Al-ZrO2, Ti-Ag-ZrO2, Ti-Ti-Ag-ZrO2, Ti-Bragg and Ti-TiO2-Bragg) were subjected to nanoindentation experiments and examined using scanning electron microscopy and focused ion beam cross sectional analysis. Three coating systems contained adhesion layers (10nm of Ti or 60nm of TiO2 layers). The fracture toughness of selected samples was assessed applying two different models from literature, a classical for bulk materials and an energy-based model, which was further developed and adjusted. The ZrO2 based coating systems (total film thicknesstoughness between 2.70 and 3.70MPam(1/2) was calculated using an energy-based model. The classical model was applied to Bragg coated samples and their fracture toughness ranged between 0.70 and 0.80MPam(1/2). Furthermore, coating systems containing an additional layer (Ti-Ti-Al-ZrO2, Ti-Ti-Ag-ZrO2 and Ti-TiO2-Bragg) showed an improved adhesion between the substrate and the coating. The addition of a Ti or TiO2 layer improved the adhesion between substrate and coating. The validity of the models for the assessment of the fracture toughness depended on the layer structure and fracture profile of the samples investigated here (classical model for thick coatings and energy-based model for thin coatings).

    The preparation of cross-sectional specimens for AEM studies of materials such as ceramic coated tungsten carbide presents some unique problems. Pieces joined by the use of epoxides often separate at the interface between the WC and ceramic coating during the initial mechanical grinding and subsequent thinning process as a result of the vibration and physical strain placed on the sample. These problems have been overcome through the use of a preparation process which essentially encapsulates the sample within the confines of an epoxy filled quartz tube. This preparation process has allowed for facile AEM cross-sectional analysis of TiN/TiCN coatings on WC-Co substrates, and has revealed two distinct grain morphologies within the TiCN coating.

    Mango (Mangifera indica L.) fruit has a relatively short storage life due to perishable nature. In order to increases the storage life of langra mangoes, fruits were coated with sunflower wax. Mangoes were stored at room and refrigerated temperature. Sunflower wax coating protects the mangoes in greater proportion to change their color, weight loss, moisture loss, pH and total soluble solids content. The sensorial panel also favors the grander role of sunflower wax coating. Application of sunflower wax coatings had no effect on vitamin C content of mangoes variety and could increases mango storage time around 30 days under regular storage conditions. Sunflower wax coating also inhibited the growth of micro-organisms. The data reveal that by applying a sunflower wax coating effectively prolongs the quality which attributes and extends the shelf life of mango. (author)

    1975-01-01

    A coating technique for electron microscope autoradiography is described which combines the advantage of forming an emulsion film by a dripping method with the ease of coating sections already on grids. Sections are coated so that a formvar support film separates the section and the emulsion crystals. This intermediate layer of formvar ensures a random distribution of the emulsion crystals. Using light gold sections, Ilford L-4 emulsion and Microdol-X development, the resolution of this technique, as determined by the half distance method, was 150 nm. The additional layer of formvar slightly reduced the image quality with biological samples in the electron microscope. This technique has a minimal loss of resolution and image quality for moderate resolution electron microscope autoradiography. (author)

    2010-01-01

    Future rotorcraft propulsion systems are required to operate under highly-loaded conditions and in harsh sand erosion environments, thereby imposing significant material design and durability issues. The incorporation of advanced thermal barrier coatings (TBC) in high pressure turbine systems enables engine designs with higher inlet temperatures, thus improving the engine efficiency, power density and reliability. The impact and erosion resistance of turbine thermal barrier coating systems are crucial to the turbine coating technology application, because a robust turbine blade TBC system is a prerequisite for fully utilizing the potential coating technology benefit in the rotorcraft propulsion. This paper describes the turbine blade TBC development in addressing the coating impact and erosion resistance. Advanced thermal barrier coating systems with improved performance have also been validated in laboratory simulated engine erosion and/or thermal gradient environments. A preliminary life prediction modeling approach to emphasize the turbine blade coating erosion is also presented.

    1981-01-01

    The reported study had the purpose to examine variations in cyclic life and in adhesive/cohesive coating strength. Possible effects of heating rate, stress reversal, temperature level, and ceramic deposition methods on coating life were also investigated. Life cycle data for 22 thermal barrier coated rods were examined and found to be statistically modeled by normal or log-normal distributions. The sample mean was 1330 cycles with a standard deviation of 520 cycles. Adhesive/cohesive pulloff strength data for 20 thermal barrier coated flat head piston specimens were taken. The average pulloff stress was 9 MPa with a standard deviation of 4.2 MPa. It was found that variations in heating rate can produce significant variations in the life cycle data.

    Full Text Available Chitosan coating serve as an antioxidant and micro-diffusion barrier and prevents the loss of water, texture, odour, color or overall accessibility in seafood. The preservation of shrimps using chitosan dips seems promising and effective, as demonstrated in this study. The antimicrobial property of chitosan is infhenod by slightly acidic pH. This work also showed that the shelf life of Penaeus monodon coated with chitosan dips extends the shelf life of shrimp.

  1. Effect of Hf Additions to Pt Aluminide Bond Coats on EB-PVD TBC Life

    2000-01-01

    Small Hf additions were incorporated into a Pt aluminide coating during chemical vapor deposition (CVD) on single crystal RENE N5 substrates. Standard yttria-stabilized zirconia top coats were subsequently deposited onto the coated substrates by electron beam-physical vapor deposition (EB-PVD). The coated substrates underwent accelerated thermal cycle testing in a furnace at a temperature in excess of 1121 C (2050 F) (45 minute hot exposure, 15 minute cool to approximately 121 C (250 F)) until the thermal barrier coating (TBC) failed by spallation. Incorporating Hf in the bond coat increased the TBC life by slightly more than three times that of a baseline coating without added Hf. Scanning electron microscopy of the spalled surfaces indicated that the presence of the Hf increased the adherence of the thermally grown alumina to the Pt aluminide bond coat. The presence of oxide pegs growing into the coating from the thermally grown alumina may also partially account for the improved TBC life by creating a near-surface layer with a graded coefficient of thermal expansion.

    Cross-sectional structural characteristics of the CVD diamond coatings deposited on the tungsten carbide (WC-Co) substrates were analysed using Raman imaging technique. The grain size of the nanocrystalline diamond (NCD) coatings was observed to deviate from the nanocrystallinity with increasing thickness and exhibited the surface characteristics of microcrystalline diamond (MCD). However, thick diamond coatings with surface nanocrystallinity is the key requirement for load-bearing tribological applications. Tribological tests have clearly indicated the significance and need for the top-layer nanocrystallinity. Graded composite diamond coatings with an architecture of NCD/transition-layer/MCD/WC-Co are potentail candiadates to realize thick diamond coatings with top-layer nanocrystallinity. Residual stresses along the cross-section of the graded composite diamond coatings were analysed using Raman imaging technique, which confirmed the improved interfacial integrity of the graded composite diamond coatings.

    2017-01-01

    Full Text Available Based on polydimethylsiloxane, three-component coatings were prepared with different content of luminescence powder. The results showed that the illuminance of coatings increases with the content of luminescence powder, decays exponentially with the afterglow time, increases exponentially with the increase of exposure time. The afterglow illuminance augments with irradiated light illuminance. All coatings are hydrophobic and oleophilic. Surface free energy decreases with the increase of luminescence powder. They have highest impact-resistance and bend flexibility. The luminescence powder does not change obviously the shore hardness, tensile breaking strength, breaking elongation rate, elastic modular and roughness of coatings. The static test panels in sea generally could be covered obviously by biofouling including sponges, bryophytes and mussels, hydra, kelp, green algae after 2 months of immersion during growing season. But it never found that the barnacle attached on the coating surface during 4 years of immersion test. The static anti-fouling ability of the coatings is very limited. In addition, the sea creatures attached on the coating surface can be easily removed; even attached organisms will fall off and expose again the smooth coating surface. Consequently, all coatings with long-life afterglow fluorescent have a significant effect on preventing adhesion of barnacle and fouling-release performance.

    A life cycle assessment (LCA) is carried out to compare nanoclay-reinforced polymer wire coatings with conventional ones. While the conventional wire coatings contain standard halogen free retardants, in reinforced coatings, montmorillonite (nanoclay) is incorporated into electric cable linings as a rheological agent for an increased resistance to fire. In addition, a reduced load of standard halogen free retardants is obtained. The synergistic effect of the montmorillonite on traditional flame retardant additives (by the formation of a three-dimensional char network) can lead to a revolution in wire production. The application of nanoclays contributes also to anti-dripping effect and flexibility increase [1]. Some producers have already started commercializing wire with nanotechnology-based coating; in the short term the use of nanoclay in wire coating production will probably reach a significant market share replacing traditional formulations. The main aim of this study is to compare the environmental impacts along the life cycle of a traditional wire coating (mineral flame retardants like ATH or MDH in a polymer matrix) with the nanoclay-reinforced wire coating, where the montmorillonite replaces a low percentage of the mineral flame retardant. The system boundaries of the study include the following unit processes: nanoclay production, thermoplastic material and mineral flame retardants production, cable coating manufacturing by extrusion and different end of life scenarios (recycling, incineration and landfill disposal). Whereas nanoreinforced composites have shown and increased fire retardance, the addition of nanomaterials seems to have no significant relevance in the environmental assessment. However, the lack of nano-specific characterization factors for nanomaterials and emission rates associated to the different life cycle stages -mainly in the extrusion and use phase, where accidental combustions can take place- still remains a challenge for realistic

    Full Text Available An edible coating functionalized with pomegranate polyphenols was designed. Different blends of candelilla wax, gum arabic, jojoba oil, and pomegranate polyphenols were formulated in order to improve the shelf life quality of pears (variety Bartlett, and all formulations were applied by immersion onto the fruit surface. Coated pears with and without polyphenols and uncoated pears (control were stored under the same conditions. Fruits were analyzed to evaluate changes in their physicochemical, microbiological, and sensorial properties during 30 days of storage at room temperature. Coated pears coded as T13 (candelilla wax 3%, gum arabic 4%, jojoba oil 0.15%, and pomegranate polyphenols 0.015% extended and improved their shelf life quality due to the minimization of the physic-chemical changes and sensorial properties. Therefore, the results indicated that the formulated edible coating has potential to extend the shelf life and maintain quality of pears. It was probed that coated pears were accepted for consumers as a good product. Edible coating application represents a good alternative to keep pears freshness for longer periods.

    Full Text Available In Latin-America, there are countries with high production levels of green bell peppers, which requires of new strategies of conservation for their international trade. Traditional techniques of preservations do not guarantee to prolong the shelf life of these kinds of fruits, for this reason, in the present study, the Influence of different edible coating formulations on shelf-life quality of green bell peppers was studied. Three different biopolymers (pectin, arabic, and xanthan gums were evaluated in mixtures with candelilla wax as hydrophobic phase, jojoba oil as plasticizer and a crude extract of polyphenols as source of bioactive compounds. Green bell peppers were immersion-treated and then stored at room temperature. Response variables were: weight loss, color, appearance, pH, total soluble solids and firmness changes which were kinetically determined. All peppers treated with edible-coating showed a significant difference (Tukey, p≤0.05 in weight loss compared to control treatment (without edible coating, while a lower level of deterioration was observed in fruits treated with edible coating formulated with arabic gum, but appearance remained similar among fruits treated with different edible coatings. Use of mixtures of biopolymers, candelilla wax, jojoba oil and polyphenols to develop edible and functionalized coatings significantly extended shelf life of green bell pepper.

The current state and trend of the research, methods in vogue related to the failure analysis, and long-term behavior and life prediction of EBCITBC systems are reported. Also, the perceived failure mechanisms, variables, and related uncertainties governing the EBCITBC system life are summarized. A combined heat transfer and structural analysis approach based on the oxidation kinetics using the Arrhenius theory is proposed to develop a life prediction model for the EBC/TBC systems. Stochastic process-based reliability approach that includes the physical variables such as gas pressure, temperature, velocity, moisture content, crack density, oxygen content, etc., is suggested. Benefits of the reliability-based approach are also discussed in the report.

    The interior quality, shell impact strength and functional characteristics of eggs coated with chitosan and lysozyme-chitosan combinations were evaluated for enhancing egg freshness during storage. A 10% (w/w) lysozyme solution was incorporated into 1% (w/w) chitosan film-forming solution at ratios of 0, 10, 20 and 60% (w/w). Storage time and coating had significant effects on Haugh unit, yolk index, weight loss, albumen pH, dry matter, relative whipping capacity (RWC) and albumen viscosity. Uncoated eggs had higher albumen pH and weight loss and lower albumen viscosity. All coated eggshells showed greater puncture strength than uncoated eggshells, resulting in extended shelf life. The 20 and 60% lysozyme-chitosan coatings were more effective in maintaining the internal quality of eggs (e.g. pH, dry matter and RWC). Attributes such as pH, dry matter and RWC were better after the 20% lysozyme-chitosan treatment than after the other treatments. The 10, 20 and 60% lysozyme-chitosan coatings, considered active packaging, showed promising attributes. They could be a viable alternative to existing techniques for maintaining the internal quality of fresh eggs during long-term storage. Chitosan coatings also improved shell strength. This study also confirms that measurements of albumen quality (pH, dry matter, viscosity and RWC) are excellent indicators of egg freshness. © 2013 Society of Chemical Industry.

    The aim of this study was to analyze the influence of rotary instruments' geometry and surface titanium-nitride (TiN) treatment on the fatigue fracture, through the comparison of cyclic fatigue resistance of two endodontic systems that have similar cross-sectional design and different surface coating. 130 Mtwo (10/.04; 15/.05; 20/.06; 25/.06; 30/.05; 35/.04; 40/.04) and Easy Shape (15/.04; 20/.05; 25/.06; 30/.05; 35/.04; 40/.04) were tested for cyclic fatigue resistance. Time to fracture (TtF) was determined by counting the seconds of continuous rotation until final fracture in an artificial canal with 60° angle and a 5 mm radius of curve. The fracture surface of each fragment was examined with a scanning electron microscope (SEM). Data were subjected to one-way analysis of variance (ANOVA) and Tukey post-hoc tests. Mtwo perform a significantly (P0,05). Mtwo exhibit a higher NCF thanks to the smaller metal volume contained in their core. Titanium-nitride coating doesn't influence the performance of Easy Shape instruments on static test of cyclic fatigue.

    Uttarwar, Rohan G.

    In recent years, nanocoatings with exceptionally improved and new performance properties have found numerous applications in the automotive, aerospace, ship-making, chemical, electronics, steel, construction, and many other industries. Especially the formulations providing multiple functionalities to cured paint films are believed to dominate the coatings market in the near future. It has shifted the focus of research towards building sustainable coating recipes which can deliver multiple functionalities through applied films. The challenge to this exciting area of research arrives from the insufficient knowledge about structure-property correlations of nanocoating materials and their design complexity. Experimental efforts have been successful in developing certain types of nanopaints exhibiting improved properties. However, multifunctional nanopaint design optimality is extremely difficult to address if not impossible solely through experiments. In addition to this, the environmental implications and societal risks associated with this growing field of nanotechnology raise several questions related to its sustainable development. This research focuses on the study of a multiscale sustainable nanocoating design which can have the application from novel function envisioning and idea refinement point of view, to knowledge discovery and design solution derivation, and further to performance testing in industrial applications. The nanocoating design is studied using computational simulations of nano- to macro- scale models and sustainability assessment study over the life-cycle. Computational simulations aim at integrating top-down, goals/means, inductive systems engineering and bottom-up, cause and effect, deductive systems engineering approaches for material development.

    Highly water-resistant and solar-reflective coatings for low-slope roofs are potentially among the most economical retrofit approaches to thermal management of the building envelope. Therefore, they represent a key building technology research program within the Department of Energy. Research efforts in industry and the Department of Energy are currently under way to increase long-term solar reflectance on a number of fronts. These include new polymer coatings technologies to provide longer-lasting solar reflectivity and improved test methodologies to predict long-term soiling and microbial performance. The focus on long-term improvements in soiling and microbial resistance for maximum reflectance does not address the single most important factor impacting the long-term sustainability of low-slope roof coatings: excellent water resistance. The hydrophobic character of asphaltic roof products makes them uniquely suitable for water resistance, but their low albedo and poor exterior durability are disadvantages. A reflective coating that maintains very high water resistance with increased long-term resistance to soiling and microbial activity would provide additional energy savings and extend roof service life.

    The importance of advanced e-beam writing system and chemically amplified resist (CAR) coated blank is increasing gradually in high-end grade photomask manufacture according to CD embodiment of 90 nm and beyond technology node requiring because of the shrinkage of design rule in the semiconductor industry. However, many studies have been reported that CAR has several troubles and especially, CAR sensitivity change is occurred by airborne molecular contamination (AMC). So, the storage life of CAR coated blank is shortened. This problem may cause the difficulty of high-end grade photomask manufacture because it is hard to secure stable mean to target (MTT) and CD uniformity by sensitivity change, T-top profile and footing profile. Therefore, the purpose of this paper is to investigate the storage life extension for high performance CAR coated blank through improvement of the packing materials. Firstly, a variety of packing materials were collected and the selected packing materials were analyzed by Automatic Thermal Desorption Gas Chromatograph/Mass Spectrometer (ATD GC/MS) and Ion Chromatograph (IC) to examine AMC generated from the packing materials. As a result, molecular condensables such as alcohols, hydrocarbons and fatty acids were detected and molecular acids and molecular bases those are NH4+, Cl-, NOx- and SOx- were also detected from the packing materials, respectively. From the above results, we selected the best packing materials which generated the least AMC and the worst packing materials which generated the most AMC. Additionally, we verified photomask process with CAR coated blanks which were packed with those packing materials with post coating delay (PCD) by 50 kV e-beam writing system. In consequence, dose to clear (DTC) showed 4.6 μC/cm2 at 0 day PCD for both of the best and the worst packing materials of CAR coated blank. After 90 days PCD, DTC variation was only 0.4 μC/cm2 for the best packing materials, but DTC variation of 4.0 μC/cm2

    The increased consumer demand for high quality, extended shelf life, ready to eat foods has initiated the development of several innovative techniques to keep their natural and fresh appearance as long as possible and at the same time render them safe. Packaging has been an important element in these preservation concepts for providing the appropriate (mechanical and functional) protection to the commodity. Since synthetic packaging materials contribute to the environmental pollution, edible coatings and packages have been proposed to replace or complement conventional packaging. Biodegradable and edible films and coatings are made from naturally occurring polymers and functional ingredients, and formed on the surface of food products. Edible films and coating have long been known to protect perishable food products from deterioration and reduce quality loss. These films should have acceptable sensory characteristics, appropriate barrier properties (CO(2), O(2), water, oil), microbial, biochemical and physicochemical stability, they should be safe, and be produced by simple technology in low cost. Also they can act as effective carrier for antioxidant, flavor, color, nutritional or anti-microbial additives. Patents on edible films and food products are also discussed in this article.

    The aim of this study was to evaluate quinoa protein (Q), chitosan (CH) and sunflower oil (SO) as edible film material as well as the influence of this coating in extending the shelf-life of fresh blueberries stored at 4 °C and 75% relative humidity. These conditions were used to simulate the storage conditions in supermarkets and represent adverse conditions for testing the effects of the coating. The mechanical, barrier, and structural properties of the film were measured. The effectiveness of the coating in fresh blueberries (CB) was evaluated by changes in weight loss, firmness, color, molds and yeast count, pH, titratable acidity, and soluble solids content. The tensile strength and elongation at break of the edible film were 0.45 ± 0.29 MPa and 117.2% ± 7%, respectively. The water vapor permeability was 3.3 × 10(-12) ± 4.0 × 10(-13) g s(-1) m(-1) Pa(-1). In all of the color parameters CB presented significant differences. CB had slight delayed fruit ripening as evidenced by higher titratable acidity (0.3-0.5 g citric acid 100 g(-1)) and lower pH (3.4-3.6) than control during storage; however, it showed reduced firmness (up to 38%). The use of Q/CH/SO as a coating in fresh blueberries was able to control the growth of molds and yeasts during 32 days of storage, whereas the control showed an increasing of molds and yeast, between 1.8 and 3.1 log cycles (between 20 and 35 days). © 2015 Society of Chemical Industry.

    2001-01-01

    The present study was conducted to evaluate the combined effect of low-dose gamma irradiation and antimicrobial coating on the shelf life of pre-cooked shrimp (Penaeus spp.). Antimicrobial coatings were obtained by incorporating various concentrations of thyme oil and trans-cinnamaldehyde in coating formulations prepared from soy or whey protein isolates. Coated shrimps were stored at 4±1°C under aerobic conditions and were periodically evaluated for aerobic plate counts (APCs) and Pseudomonas putida. Sensory evaluations were performed for appearance, odor, and taste using a hedonic test. Results showed that gamma irradiation and coating treatments had synergistic effects (p < = 0.05) in reducing the APCs and P. putida with at least a 12-day extension of shelf life. Without irradiation, the inhibitory effects of the coating solutions were closely related to the concentration of thyme oil and trans-cinnamaldehyde. No detrimental effects of gamma irradiation on organoleptic parameters (appearance, odor, and taste) were observed. However, incorporation of thyme oil and trans-cinnamaldehyde reduced the acceptability scores for taste and odor

    Superhydrophobic coating has extremely high application value and practicability. However, some difficult problems such as weak mechanical strength, the need for expensive toxic reagents, and a complex preparation process are all hard to avoid, and these problems have impeded the superhydrophobic coating's real-life application for a long time. Here, we demonstrate one kind of omnipotent epoxy resins @ stearic acid-Mg(OH)2 superhydrophobic coating via a simple antideposition route and one-step superhydrophobization process. The whole preparation process is facile, and expensive toxic reagents needed. This omnipotent coating can be applied on any solid substrate with great waterproof ability, excellent mechanical stability, and chemical durability, which can be stored in a realistic environment for more than 1 month. More significantly, this superhydrophobic coating also has four protective abilities, antifouling, anticorrosion, anti-icing, and flame-retardancy, to cope with a variety of possible extreme natural environments. Therefore, this omnipotent epoxy resins @ stearic acid-Mg(OH)2 superhydrophobic coating not only satisfies real-life need but also has great application potential in many respects.

    The present study was conducted to evaluate the combined effect of low-dose gamma irradiation (2.5 kGy) and chitosan edible coating (2%) containing grape seed extract (GSE) (0.1%) on the microbial, chemical and sensorial quality of chicken breast meat during 21 days of storage at 4 °C. The samples were periodically analyzed for microbiological (aerobic mesophilic and psychrotrophic counts), chemical (TBA, pH, aw) and sensorial (odor, appearance, and overall acceptability) characteristics. Results indicated that irradiation and the active coating had significant (P ≤ 0.05) effects on reduction of bacterial growth with at least a 14-day extension of shelf life. Results represented the protective effect of chitosan coating containing GSE against induced lipid oxidation by irradiation. All chitosan-coated samples showed lower TBA and pH values than other treatments during storage, and no significant (P > 0.05) difference was observed due to irradiation in TBA values. Results also indicated that the application of chitosan coating significantly improved the sensorial quality of the samples, and none of the evaluated sensorial attributes was significantly affected by irradiation. Based on the results obtained in this study, the application of low-dose gamma irradiation and chitosan coating containing GSE was effective in preserving the quality of fresh chicken meats and is recommended in meat products.

In order to extend the shelf life and quality of strawberry (cv. parous, effects of pectin coating enriched with different concentrations of lemon and orange peel essential oil were assessed at 20˚C for 6 days or 5˚C to 12 days. The experiment conducted based on a complete randomized design (CDR in 3 replications with 6 treatments including control (distilled water, pectin (1%, pectin enriched with orange peel essential oil (0.5 and 1% and pectin containing lemon peel essential oil (0.5 and 1%. Fruit quality was evaluated by marketing, weight loss, anthocyanin content, ascorbic acid content, total protein and chlorophyll of calyx every 3 days. Based on results coating fruits with citrus essential oil carried by pectin delayed the change in weight loss, total protein, anthocyanin content, maintained ascorbic acid content of fruits and also reduced chlorophyll destruction of calyx. The results showed that pectin coating containing lemon essential oil had a significant effect on the maintaining the visual quality of the fruit during the storage, delayed the weight loss and showed better results compared to the other coatings and to the control fruit. In addition, the maximum content of ascorbic acid and anthocyanin were obtained for strawberries coated with pectin containing lemon essential oil 1% after 12 days storage of fruits at 5˚C. All coatings significantly reduced weight loss of fresh strawberries during storage at 5˚C and 20˚C compared to the uncoated fruits. Results indicated that adding high concentrations (1% of orange peel essential oil into pectin coatings did not improve quality of fruits. In addition, it was found that adding orange peel essential oil to pectin coating accelerate decay of fruits. Based on results, pectin coating containing 1% lemon essential oil considered an appropriate treatment to improve shelf life and storage

    The imaging time-of-flight secondary-ion-mass-spectrometry (TOF-SIMS) method was utilized to address the problem of cholesterol localization in rat tissues. Rat kidneys were fixed, cryoprotected by sucrose, frozen, sectioned by cryoultramicrotomy, and dried at room temperature. The samples were either covered with a thin silver layer or analyzed uncovered in an imaging TOF-SIMS instrument equipped with an Au1-3(+)-source. The yield of desorbed secondary ions for some species was up to 600-fold higher after silver coating of the samples. Reference samples of cholesterol were silver-coated and analyzed by TOF-SIMS to define significant peaks, specific for cholesterol. Such peaks were found at m/z = 386 (C27H46O+), m/z = 493 (C27H46O107Ag+), m/z = 495 (C27H46O109Ag+), m/z = 879 (C54H92O2 107Ag+), and m/z = 881 (C54H92O2 109Ag+). The silver-cationized cholesterol (493 SIMS in the kidney sections and showed a high cholesterol content in the kidney glomeruli. A more diffuse distribution of cholesterol was also found over areas representing the cytoplasm or plasma membrane of the epithelial cells in the proximal tubules of rat kidney.

    PVD based hard coatings have remarkable achievements in order to improve Tribological and surface properties of coating tools and dies. As PVD based hard coatings have a wide range of industrial applications especially in aerospace and automobile parts where they met different chemical attacks and in order to improve industrial performance these coatings must provide an excellent resistance against corrosion, high temperature oxidation and chemical reaction. This paper focuses on study of behaviour of PVD based hard coatings under different corrosive environments like as H/sub 2/SO/sub 4/, HCl, NaCl, KCl, NaOH etc. Corrosion rate was calculate under linear sweep voltammetry method where the Tafel extrapolation curves used for continuously monitoring the corrosion rate. The results show that these coatings have an excellent resistance against chemical attack. (author)

    Chitosan has been widely used as fruit preserver and proven to extend the shelf life of many fruits, such as banana. However, banana producers and many industries in Indonesia still facing storage problems which may lead to mechanical damage of the fruits and ripening acceleration. Therefore, we have designed food storage chamber (FSC) based on bamboo material. Bamboo was selected because of material abundance in Indonesia, economically effective, and not causing an autocatalytic reaction to the ethylene gas produced by the banana. In this research, Cavendish banana that has reached the maturity level of mature green were coated with 1% chitosan and placed inside the FSC. As control treatments, uncoated banana was also placed inside the FSC as well as uncoated banana that were placed at open space. All of the treatments were placed at 25°C temperature and observed for 9 days. Water produced by respiration was reduced by the addition of charcoal inside a fabric pouch. The result showed that treatment using FSC and chitosan can delay ripening process.

    Full Text Available Background & aim: Postpartum period is accompanied by significant changes in women’s quality of life. These alterations can affect the health of mothers and children. Considering the importance of postnatal quality of life and its different contributing factors, this study aimed to compare women’s quality of life after vaginal delivery and cesarean section. Methods:This retrospective cohort study included a random sample of 2100 women, referring to Hamadan health care centers for congenital hypothyroidism screening or infant vaccination. The participants’ quality of life was examined, using Short Form-36 (SF-36 questionnaire, evaluating five periods of time including one week, two months, four months, six months, and one year after delivery (either vaginal or cesarean delivery. Data were analyzed using t-test. Results: Quality of life was significantly higher in women with vaginal delivery, compared to women with cesarean section in all periods including one week (68.77 vs. 42.44, two months (69.11 vs. 54.76, four months (78.19 vs. 53.02, six months (75.62 vs. 54.94,and one year(78.43 vs. 53.77 after delivery. Conclusion: Considering women’s higher quality of life after vaginal delivery, compared to cesarean section, it seems that vaginal delivery is a safer and less expensive option, which is recommended for all pregnant women.

    Full Text Available Abstract Background Estimates of life expectancy assist physicians and patients in medical decision-making. The time-delayed benefits for many medical treatments make an older adult's life expectancy estimate particularly important for physicians. The purpose of this study is to assess older adults' beliefs about physician-estimated life expectancy. Methods We performed a mixed qualitative-quantitative cross-sectional study in which 116 healthy adults aged 70+ were recruited from two local retirement communities. We interviewed them regarding their beliefs about physician-estimated life expectancy in the context of a larger study on cancer screening beliefs. Semi-structured interviews of 80 minutes average duration were performed in private locations convenient to participants. Demographic characteristics as well as cancer screening beliefs and beliefs about life expectancy were measured. Two independent researchers reviewed the open-ended responses and recorded the most common themes. The research team resolved disagreements by consensus. Results This article reports the life-expectancy results portion of the larger study. The study group (n = 116 was comprised of healthy, well-educated older adults, with almost a third over 85 years old, and none meeting criteria for dementia. Sixty-four percent (n = 73 felt that their physicians could not correctly estimate their life expectancy. Sixty-six percent (n = 75 wanted their physicians to talk with them about their life expectancy. The themes that emerged from our study indicate that discussions of life expectancy could help older adults plan for the future, maintain open communication with their physicians, and provide them knowledge about their medical conditions. Conclusion The majority of the healthy older adults in this study were open to discussions about life expectancy in the context of discussing cancer screening tests, despite awareness that their physicians' estimates could be inaccurate

    This study was conducted to identify the predictors, levels, and prevalence of anxiety and stress and to assess the relationship between these factors and quality of life in recently displaced Iraqis. A cross-sectional design was used. A convenience sample of 171 Iraqi refugees was recruited. The results indicated that more than half of the sample suffered from high anxiety levels, while 42.8% reported high stress. The regression model explained 46.3% of the variance in levels of quality of life. Unemployment, fewer than three family members, and high anxiety significantly predicted low-level quality of life. These three predictors need to be taken into consideration when developing health-related interventions to improve the quality of life of Iraqi refugees. © 2017 John Wiley & Sons Australia, Ltd.

  8. Life-history consequences of investment in free-spawned eggs and their accessory coats.

    Podolsky, Robert D

    2004-05-01

    The optimal trade-off between offspring size and number can depend on details of the mode of reproduction or development. In marine organisms, broadcast spawning is widespread, and external coats are a common feature of spawned eggs. Egg jelly coats are thought to influence several aspects of fertilization and early development, including the size of the target for sperm, fertilization efficiency, egg suspension time, polyspermy, embryo survival, and fecundity. These costs and benefits of investment in jelly result in trade-offs that can influence optimal reproductive allocation and the evolution of egg size. I develop an optimization model that sequentially incorporates assumptions about the function of egg coats in fertilization. The model predicts large variation in coat size and limited variation in ovum size under a broad range of conditions. Heterogeneity among spawning events further limits the range of ovum sizes predicted to evolve under sperm limitation. In contrast, variation in larval mortality predicts a broad range of optimal ovum sizes that more closely reflects natural variation among broadcast-spawning invertebrates. By decoupling physical and energetic size, egg coats can enhance fertilization, maintain high fecundity, and buffer the evolution of ovum size from variation in spawning conditions.

    The burden of sexual dysfunction among older people in many low- and middle-income countries is not well known. Understanding sexual dysfunction among older people and its impact on quality of life is essential in the design of appropriate health promotion programs. To assess levels of sexual function and their association with quality of life while controlling for different sociodemographic determinants and chronic diseases among men and women over 50 years of age in rural Indonesia. A cross-sectional study was conducted in the Purworejo District, Central Java, Indonesia in 2007. The study involved 14,958 men and women over 50 years old. The association between sexual dysfunction and quality of life after controlling for potential confounders (e.g., sociodemographic determinants and self-reported chronic diseases) was analyzed by multivariable logistic regression. Self-reported quality of life. Older men more commonly reported sexual activity, and sexual problems were more common among older women. The majority of older men and women reported their quality of life as good. Lack of sexual activity, dissatisfaction in sexual life, and presence of sexual problems were associated with poor self-reported quality of life in older men after adjustment for age, marital status, education, and history of chronic diseases. A presence of sexual problems was the only factor associated with poor self-reported quality of life in women. Being in a marital relationship might buffer the effect of sexual problems on quality of life in men and women. Sexual dysfunction is associated with poor quality of life among older people in a rural Javanese setting. Therefore, promotion of sexual health should be an integral part of physical and mental health campaigns in older populations. © 2011 International Society for Sexual Medicine.

  10. MALOCCLUSIONS AND QUALITY OF LIFE. Cross-sectional and longitudinal studies in children.

    Dimberg, Lillemor

    2015-01-01

    There are few longitudinal studies of the prevalence of malocclusions and possible self-correction of malocclusions during the development of the dentition. Early intervention might be unnecessary if self-correction of the malocclusion occurs during the transition from the primary to the permanent dentition. Most studies are cross-sectional and in those of longitudinal design, the results are inconsistent and difficult to interpret. Malocclusions may or may not influence the quality of life in children and adolescents. Thus, evaluations of the influence of different malocclusions on quality of life will certainly underpin a broader understanding and knowledge about how malocclusions affect the daily life of young patients. This information may also be important when it comes to assessing the most appropriate time for starting orthodontic treatment, not only from a professional point of view, but also, most importantly, from the patients' perspective. The overall aim of this thesis was therefore to evaluate the prevalence of malocclusions, and to document changes occurring during the development of the dentition, from the primary dentition stage at age 3, through the mixed dentition at age 7, to the early permanent dentition at age 11.5 years. Further aims were to review the current state of knowledge about the impact of malocclusions on oral health related quality of life (OHRQoL) and to investigate how malocclusions affect the quality of life in a cohort of children, aged 11.5 years, whose dental care is provided by the Swedish Public Dental Service.

    Workers in Primary Health Care are often exposed to stressful conditions at work. This study investigated the association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers. This cross-sectional study included all 797 Primary Health Care workers of a medium-sized city, Brazil: doctors, nurses, nursing technicians and nursing assistants, dentists, oral health technicians, and auxiliary oral hygienists, and community health workers. Data were collected by interviews. Quality of life was assessed using the WHOQOL-BREF; general quality of life, as well as the physical, psychological, social and environmental domains were considered, with scores from 0 to 100. Higher scores indicate a better quality of life. Poor quality of life was defined by the lowest quartiles of the WHOQOL score distributions for each of the domains. Adverse psychosocial work conditions were investigated by the Effort-Reward Imbalance model. Associations were verified using multiple logistic regression. Poor quality of life was observed in 117 (15.4%) workers. Workers with imbalanced effort-reward (high effort/low reward) had an increased probability of general poor quality of life (OR = 1.91; 1.07–3.42), and in the physical (OR = 1.62; 1.02–2.66), and environmental (OR = 2.39; 1.37–4.16) domains; those with low effort/low reward demonstrated a greater probability of poor quality of life in the social domain (OR = 1.82; 1.00–3.30). Workers with overcommitment at work had an increased likelihood of poor quality of life in the physical (OR = 1.55, 1.06–2.26) and environmental (OR = 1.69; 1.08–2.65) domains. These associations were independent of individual characteristics, job characteristics, lifestyle, perception of general health, or psychological and biological functions. There is an association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers.

    Lifestyle has a key role in having a life with quality. This is much more critical in academic community. Elite students are the scientific capital of each community; therefore, improvement of their life-style is a very crucial issue and is a way of esteeming them. This study was aimed to scrutinize the life-style of elite dental students to provide a guideline for healthy life-style for their own and for other students, as well. This descriptive and cross-sectional study was carried out on 115 Elite dental students, from a list 175 students, based upon their interest. The HPLP-II questionnaire was used which focuses on 6 behavioral fields: Spiritual Growth, Interpersonal Relations, Nutrition, Physical Activity, Health Responsibility, and Stress Management. The results also compared genders and marital status within the study group. The elite dental students were categorized in 3 age groups as 19≥ yrs (Group I), 20-22 yrs (Group II), and 23≤ yrs. (Group III) for comparison. Data were analyzed using SPSS version 19, independent t-test, one-way ANOVA, and Tukey's test. The mean score of the HPLP-II questionnaire was 2.51±0.27 (out of score 4). Spiritual growth (2.85±0.42) and physical activity (2.16±0.58) were the highest and the lowest scores, respectively. Physical activity was the only subscale different between genders ( p = 0.000). Marital status had not effect on life-style of students. Between the age groups, the physical activity was significantly different between group I and II (0.002). Elite dental students' life-style is most prominent in spiritual growth and interpersonal relationships dimensions, but is the weakest in physical activity and health responsibility behavioral attitudes. To improve the talent of all students, interventional workshops/courses aiming at modification and promotion of students' lifestyle is recommendable in the curriculum.

    The objective of the present work was to develop strategies for increasing the shelf-life of red raspberries (Rubus idaeus L.), by preventing microorganism growth. Fruits coated with alginate plus lemon essential oil (0.2%) or orange essential oil (0.1%) after 15 days of storage had less red skin than the remaining samples. The less red color verified in these samples was also coincident with the lower concentration of anthocyanins at the end of the experiment as well as the lower capacity for scavenging ABTS free radicals or quenching singlet oxygen. Cyanidin and pelargonidin glucosides were found in raspberries fruits. The edible coatings supplemented with the essential oil of orange either at 0.1% or 0.2% were very efficient for controlling yeast and mold growth after 15 days of storage. To control the development of aerobic mesophilic bacteria the use of essential oil of lemon 0.2% and essential oil of orange 0.1% were the most efficient. The application of the film improved post-harvest quality of raspberry, since the addition of essential oils of citrus films promoted to the inhibitory effect of fungi and bacteria growth after 15 days of storage, without changing quality parameters. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    This aim of this study was to assess the quality of life of Saudi female breast cancer patients and determine the effects of the sociodemographic and clinical characteristics on the quality of life of those patients. This study was designed as a cross-sectional study. The data were collected from 145 female cancer patients who were recruited from outpatient units in different clinical settings in Riyadh, Saudi Arabia, from September 2014 to February 2015. Questionnaires were distributed to the patients during their visits to the outpatient clinics after obtaining informed consent. Quality of life was assessed using a validated Arabic version of the European Organisation for Research and Treatment of Cancer (EORTC) quality of life. Among functional scales, emotional functioning scored the highest (83.25 [95% CI 79.53-86.98]). The most distressing symptom on the symptom scale was insomnia (mean 84.14 [95% CI 79.95-88.32]), followed by appetite loss (mean 80.92 [95% CI 76.51-85.33]) and dyspnoea (mean 80.00 [95% CI 75.51-84.49]). Poor functioning was found in sexual enjoyment (mean 22.52 [95% CI 17.97-27.08]) while future perspective scored the highest (mean 76.32 [95% CI 70.52-82.12]). This study shows breast cancer survivors in Saudi had a low overall global quality of life. Saudi women showed average scores on all the functional scales but the emotional ones scored the highest. Insomnia, appetite loss, and dyspnoea were the distressing symptoms on symptom scales while future perspective domain scored the highest in item of QLQ-BR23.

    Full Text Available Abstract Background Considering the complications that colostomies may cause, patient self-assessments of their social, emotional, physical, sexual and functional conditions may help their surgeons to evaluate the impact of their interventions or use supplementary methods to maintain patient functional status or decrease its loss to the minimum level. The aim of this study was to evaluate the Quality of Life in Iranian patients with colostomies and to compare the age and gender differences among them. Method This cross-sectional study was conducted from 2009 to 2010 to evaluate the quality of life of 96 patients who had undergone surgery for rectal cancer and had permanent colostomies. The European Organization for Research and Treatment of Cancers Quality of Life Questionnaire (EORTC QLQ-C30 and the EORTC QLQ-CR38 were used to assess patient Quality of Life. Results The mean scores for the functional subscales were as follows: Physical Function, 70.9 (±2.2; Role Function, 68.4 (±2.6; Emotional Function, 56.9 (±2.7; Cognitive Function, 68.7 (± 2.6; and Social Function, 64.2 (±3.3. The EORTC questionnaires showed significant differences between males and females. Males had better body image scores. Sexual Function and Sexual Enjoyment were impaired in both males and females, but males had significantly higher scores and better roles in Physical and Sexual Functions. More sexual enjoyment problems in older ages were observed in both males and females. Conclusion Having a colostomy was associated with a high level of emotional and sexual function impairment. The differing challenges between males and females should encourage us to design sex-specific interventions that improve the quality of life in this group of patients.

    Acne is a common problem in adolescent children and has a considerable impact on their quality of life. The purpose of this study was to assess health-related quality of life (HRQoL) among Serbian adolescents with acne, using 2 questionnaires: The Children's Dermatology Life Quality Index (CDLQI) and the Cardiff Acne Disability Index (CADI) and to provide a cross validation of 2 scales. This cross-sectional study was conducted among the pupils of the secondary railway-technical school in Belgrade, Serbia. 478 pupils (aged 15 - 18 years) completed 2 HRQoL questionnaires: CDLQI and CADI. We used t-test for differences between mean values of CDLQI and CADI and Spearman's rho coefficient for correlation between 2 questionnaires. Self-reported acne was present in 71.6% of pupils (64.3% boys and 35.7% girls). The overall mean CDLQI score (4.35 of max. 30) and the overall mean CADI score (3.57 of max. 15) were low, indicating a mild impairment of HRQoL among adolescants. There was good correlation between the 2 questionnaires (Spearman' rho = 0.66). The CADI and the CDLQI questionnaires represent simple and reliable instruments for the assesment of HRQoL among schoolchildren with acne. In this study, we identified 17% of boys and 18% of girls perceived their acne as a major problem. It is important to detect and treat such adolescents on time to reduce the psychosocial burden associated with acne.

    Although the option for vaginal delivery is most physiological, the achievement of cesarean section is very common in Brazil. The neonate cry represents the beginning of both processes, physiological adaptation and human vocal communication. The cry emission depends on the functioning of respiratory and laryngeal muscles, which are controlled by the nervous system. The acoustic analysis of neonate cry is useful in the assessment of healthy babies and can be used to characterize the signals of diseases through a previously multidisciplinary diagnosis, with immediate medical intervention. The present study compared the acoustic cry characteristics of 30 healthy newborn after a cesarean section and 30 healthy newborn after a vaginal delivery, of both genders, from the exact moment of birth until the first 5 min of life. Using the softwares VOXMETRIA and GRAM, it was possible to analyze the duration, frequency, intensity, occurrence, localization and inspiratory phonation, besides the type of spectrographic tracings. The acoustic cry characteristics of newborns after a C section and a vaginal delivery could evidence not only harmonic, expiratory, acute and strong emissions, but also emissions rich in sounds and varied in types of melody. The differences found can be related to the physiology of birth.

    Full Text Available Turning hardened component with PCBN and ceramic inserts have been extensively used recently and replaces traditional grinding operation. The use of inexpensive multilayer coated carbide insert in hard turning is lacking and hence there is a need to investigate the potential and applicability of such tools in turning hardened steels. An attempt has been made in this paper to have a study on turning hardened AISI 4340 steel (47 ± 1 HRC using coated carbide inserts (TiN/TiCN/Al2O3/ZrCN under dry environment. The aim is to assess the tool life of inserts and evolution of flank wear with successive machining time. From experimental investigations, the gradual growth of flank wear for multilayer coated insert indicates steady machining without any premature tool failure by chipping or fracturing. Abrasion is found to be the dominant wear mechanisms in hard turning. Tool life of multilayer coated carbide inserts has been found to be 31 minute and machining cost per part is Rs.3.64 only under parametric conditions chosen i.e. v = 90 m/min, f = 0.05 mm/rev and d = 0.5 mm. The mathematical model shows high determination coefficient, R2 (99% and fits the actual data well. The predicted flank wear has been found to lie very close to the experimental value at 95% confidence level. This shows the potential and effectiveness of multilayer coated carbide insert used in hard turning applications.

    Full Text Available The aim of this study was to evaluate the effect of gelatin coating incorporated with Aloe vera gel (50,100% and green and black tea extracts (5,10% on physicochemical, microbial, and sensorial properties of fresh-cut oranges at 4°C for 17 days. Significant differences in terms of quality parameters were observed between the control and coated fresh-cut oranges. The highest variation of quality parameters was observed in control, while the least variations were observed in coated slices with 100% Aloe vera and 10% green tea extract. The weight loss was increased with time, but the coating treatment especially with 100% Aloe vera had significant effect on the prevention of weight loss. Also, Aloe vera coated samples obtained the highest score in sensory evaluation. Coating with gelatin incorporated with Aloe vera and green tea extracts successfully retarded the microbial growth and therefore extended the shelf life of fresh-cut oranges during cold storage.

    Full Text Available This paper considers the influence of thickness of multilayered nano-structured coatings Ti-TiN-(TiCrAlN and Zr-ZrN-(ZrCrNbAlN on tool life of metal cutting tools at various cutting speeds (vc = 250, 300, 350 and 400 m·min−1. The paper investigates the basic mechanical parameters of coatings and the mechanism of coating failure in scratch testing depending on thickness of coating. Cutting tests were conducted in longitudinal turning of steel C45 with tools with the coatings under study of various thicknesses (3, 5, and 7 µm, with an uncoated tool and with a tool with a “reference” coating of TiAlN. The relationship of “cutting speed vc—tool life T” was built and investigated; and the mechanisms were found to determine the selection of the optimum coating thickness at various cutting speeds. Advantages of cutting tools with these coatings are especially obvious at high cutting speeds (in particular, vc = 400 m·min−1. If at lower cutting speeds, the longest tool life is shown by tools with thicker coatings (of about 7 μm, then with an increase in cutting speed (especially at vc = 400 m·min−1 the longest tool life is shown by tools with thinner coating (of about 3 μm.

    Time-sectioning cryogenic scanning electron microscopy (cryo-SEM) is a unique method of visualizing how the microstructure of liquid coatings evolves during processing. Time-sectioning means rapidly freezing (nearly) identical specimens at successively later stages of the process; doing this requires that coating and drying be well controlled in the dry phase inversion process, and solvents exchange likewise in the wet phase inversion process. With control, frozen specimens are fractured, etched by limited sublimation, sputter-coated, and imaged at temperatures of ca -175°C. The coatings examined were of cellulose acetate, of high and low molecular weights, and polysulfone in mixed solvents and nonsolvents: acetone and water with cellulose acetate undergoing dry phase inversion; and tetrahydrofuran, dimethylacetamide, ethanol with polysulfone undergoing dry-wet phase inversion. All coatings, cast on silicon substrates, were initially homogeneous. The initial compositions of the high and low molecular weight cellulose acetate ternary solutions were "off-critical" and "near-critical", respectively, connoting their proximities to the critical or plait point of the phase diagram. The initial composition of the polysulfone quaternary solution was located near the binodal of the pseudo-ternary phase diagram. It appeared that as the higher molecular weight cellulose acetate coating dries, it nucleates and grows polymer-poor droplets that coalesce into a bicontinuous structure underlying a thin, dense skin. Bicontinuity of structure was verified by stereomicroscopy of the dry sample. The lower molecular weight cellulose acetate coating phase-separates, seemingly spinodally, directly into a bicontinuous structure whose polymer-rich network, stressed by frustrated in-plane shrinkage, ruptures far beneath the skin in some locales to form macrovoids. When, after partial drying, the polysulfone coating was immersed in a bath of water, a nonsolvent, it appeared to swell in

    Full Text Available Abstract Background Quality of Life measurements are necessary tools for effectively evaluating health services. In the population of patients afflicted with war-related blindness in Iran, such measurements have yet to be documented and utilized. "The design and implementation of this study involved the determination of a baseline score for QOL in a population of Iranian blinded in the Iraq-Iran war in order to facilitate the design of interventions intended to improve the population's QOL." Methods This was a cross-sectional study of a representative population of 250 war victims blind in both eyes at a 14-day recreational conference. Results Participants had a mean age of 43.20(SD8.34 and their composition was 96.5% male and 3.5% female with a mean SF-36 QOL score of 59.20(SD22.80. An increasing level of education among the participants correlated with a higher QOL score (p = 0.006. The QOL also has a significant correlation to number of injuries (p Conclusions As blind war survivors' age, they will present with a greater set of burdens despite their relatively better QOL in the physical component scale when compared with lower limb amputees. Risk factors of cardiovascular attack such as high blood pressure and hypercholesterolemia were present and need future interventions. Key words Quality of life, blindness, SF36, health

    End-of-life implantable cardioverter defibrillator deactivation discussions should commence before device implantation and be ongoing, yet many implantable cardioverter defibrillators remain active in patients' last days. To examine associations among implantable cardioverter defibrillator knowledge, patient characteristics and attitudes to implantable cardioverter defibrillator deactivation. Cross-sectional survey using the Experiences, Attitudes and Knowledge of End-of-Life Issues in Implantable Cardioverter Defibrillator Patients Questionnaire. Participants were classified as insufficient or sufficient implantable cardioverter defibrillator knowledge and the two groups were compared. Implantable cardioverter defibrillator recipients ( n = 270, mean age 61 ± 14 years; 73% male) were recruited from cardiology and implantable cardioverter defibrillator clinics attached to two tertiary hospitals in Melbourne, Australia, and two in Kentucky, the United States. Participants with insufficient implantable cardioverter defibrillator knowledge ( n = 77, 29%) were significantly older (mean age 66 vs 60 years, p = 0.001), less likely to be Caucasian (77% vs 87%, p  = 0.047), less likely to have received implantable cardioverter defibrillator shocks (26% vs 40%, p = 0.031), and more likely to have indications of mild cognitive impairment (Montreal Cognitive Assessment score defibrillator knowledge was associated with attitudes suggesting unwillingness to discuss implantable cardioverter defibrillator deactivation, even during the last days towards end of life ( p defibrillator recipients, especially those who are older or have mild cognitive impairment, often have limited knowledge about implantable cardioverter defibrillator deactivation.

    Full Text Available Background: Acne is a common problem in adolescent children and has a considerable impact on their quality of life. Aims: The purpose of this study was to assess health-related quality of life (HRQoL among Serbian adolescents with acne, using 2 questionnaires: The Children′s Dermatology Life Quality Index (CDLQI and the Cardiff Acne Disability Index (CADI and to provide a cross validation of 2 scales. Methods: This cross-sectional study was conducted among the pupils of the secondary railway-technical school in Belgrade, Serbia. 478 pupils (aged 15 - 18 years completed 2 HRQoL questionnaires: CDLQI and CADI. We used t-test for differences between mean values of CDLQI and CADI and Spearman′s rho coefficient for correlation between 2 questionnaires. Results: Self-reported acne was present in 71.6% of pupils (64.3% boys and 35.7% girls. The overall mean CDLQI score (4.35 of max. 30 and the overall mean CADI score (3.57 of max. 15 were low, indicating a mild impairment of HRQoL among adolescants. There was good correlation between the 2 questionnaires (Spearman′ rho = 0.66. Conclusion: The CADI and the CDLQI questionnaires represent simple and reliable instruments for the assesment of HRQoL among schoolchildren with acne. In this study, we identified 17% of boys and 18% of girls perceived their acne as a major problem. It is important to detect and treat such adolescents on time to reduce the psychosocial burden associated with acne.

    The aims of our study were to compare quality of life (QOL) in obese patients after bariatric surgery with that in controls seeking surgery and to investigate which factors are associated with QOL in the Moorehead-Ardelt Quality of Life Questionnaire II (MA II). This was a cross-sectional study. The operated group consisted of patients after laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass. The MA II was administered by e-mail to 305 patients 12-18 months after surgery. The control groups consisted of 101 obese patients. We compared the QOL scores and considered good and very good outcomes to be satisfactory. Multiple logistic regression and correlation analysis was performed to identify factors associated with QOL. In the operated group, the total MA II score was 1.70 ± 0.76, which was higher than 0.59 ± 1.17 in the control group. The score adjusted for the type of surgery was comparable. The prevalence of satisfactory QOL outcomes was similar in both post-operative subgroups and was still higher than in the control group. We identified four factors associated with higher QOL in obese patients. Weight loss was not correlated with total score in MAII. This study demonstrates that patients after bariatric surgery have a higher score in MA II, which reflects better QOL. The scoring adjusted by type of operation is comparable. QOL among obese patients is dependent on age, gender, history of bariatric surgery, and partnered status. Body mass reduction was not associated with outcome in MAII.

    Frailty may be associated with reduced life satisfaction (LS). The objectives of this paper are to determine if (1) frailty is associated with LS in community-dwelling older adults in cross-sectional analyses; (2) frailty predicts LS five years later; and (3) specific domains of LS are preferentially associated with frailty. This paper presents analysis of an existing population-based cohort study of 1,751 persons aged 65+ who were assessed in 1991, with follow-up five years later. LS was measured using the terrible-delightful scale, which measures overall LS and LS in specific domains. Frailty was measured using the Brief Frailty Instrument. Analyses were adjusted for age, gender, education, and marital status. Frailty was associated with overall LS at time 1 and predicted overall LS at time 2. This was seen in unadjusted analyses and after adjusting for confounding factors. Frailty was associated with all domains of LS at time 1, and predicted LS at time 2 in all domains except housing and self-esteem. However, the effect was stronger for LS with health than with other domains for both times 1 and 2. Frailty is associated with LS, and the effect is strongest for LS with health.

    Full Text Available Abstract The mango has short postharvest shelf life which varies from 6 to 10 days at room temperature in its fresh form. The objective of this study was to evaluate the effect of usage of edible coatings based of cassava starch and chitosan on post-harvest shelf life of mango. Mangoes of Tommy Atkins variety were covered with nine different formulations of coatings in a factorial block experimental design. The fruits were stored at 25 °C and evaluated during storage for the weight loss (%, color parameters, sensory attributes evaluated by trained panel, the rate of CO2 production and microbiological contamination on the peels. Results analysed by linear regressions and ANOVA, demonstrated that chitosan showed significant effect on weight loss (% and on values of L*, a*, b*, chroma, ºhue, peel color, texture, aroma and time which correlated well for suitability of fruit consumption. The formulation containing 0.25% of chitosan and 0.5% of cassava starch showed most favorable results as it presented a post-harvest shelf life of 3 days more than the control fruits and lower rates of CO2 production, showing that this coating actually decreased the rate of the respiratory processes of mango, without compromising the proper ripening of the fruit.

    Yasuharu Tokuda

    Full Text Available BACKGROUND: There is growing interest in psychosocial factors with positive attitudes, such as interpersonal trust, as determinants for Quality-of-life (QOL or subjective well-being. Despite their longevity, Japanese people report a relatively poor subjective well-being, as well as lower interpersonal trust. Our aim in this study was to evaluate the possible association between interpersonal trust and QOL among Japanese people. METHODOLOGY AND PRINCIPAL FINDINGS: Based on the cross-sectional data for Japanese adults (2008, we analyzed the relationship between interpersonal trust and each of four domains of the WHOQOL-BREF. Interpersonal trust was assessed using three scales for trust in people, in human fairness and in human nature. In a total of 1000 participants (mean age: 45 years; 49% women, greater trust was recognized among women (vs. men, those aged 60-69 (vs. 20-29, or the high-income group (vs. low-income. Each of three trust scales was positively correlated with all domains of QOL. Multiple linear-regression models were constructed for each of QOL and the principal component score of the trust scales, adjusted for age, gender, area size of residence, income, education, and occupation. For all QOL domains, interpersonal trust was significantly and positively associated with better QOL with p<0.001 for all four domains including physical, psychological, social, and environmental QOL. Other factors associated with QOL included gender, age class, area size of residence, and income. Education and occupation were not associated with QOL. CONCLUSIONS AND SIGNIFICANCE: Greater interpersonal trust is strongly associated with a better QOL among Japanese adults. If a causal relationship is demonstrated in a controlled interventional study, social and political measures should be advocated to increase interpersonal trust for achieving better QOL.

    Lumbar spondylolysis (LS) has been the subject of several studies focusing on adolescent athletes. Few, if any, studies have examined LS in the general population. Lysis of the pars interarticularis of the vertebra may be associated with slipping (olisthesis), or it may be stable. In the present survey of lumbar radiographs and general epidemiological data recorded from the Copenhagen Osteoarthritis Study cohort of 4.151 subjects (age range, 22–93 years), we identified the distribution and individual risk factors for LS-development. Men were significantly more at risk of L5 spondylolysis (P = 0.002). There were no sex-specific significant differences regarding LS-incidence at the L4 level. We found no significant differences of risk of LS between nulliparous or multiparous women (L4 P = 0.54/L5 P = 0.35). Furthermore, we found no significant relationship between age at menopause and LS-development. Increased lumbar lordosis was associated to L4/L5 spondylolysis in men (L4 P spondylolysis (P spondylolysis in both men and women (P spondylolysis. The prevalence of LS increases throughout life and is apparently not a condition restricted to adolescence. Although the cross-sectional nature of the present study prevents an exact estimate of the age at onset; future, sequential studies of the cohort may provide us with some important answers on this topic. Apart from aging–obesity, lordotic angle and pelvic inclination were found to be individual risk factors for LS. PMID:17120072

    Full Text Available Gastrointestinal angiodysplasias may cause anemia. Quality of life (QoL is a valid patient reported outcome and improvement of QoL represents an important treatment goal. There is a paucity of data on the effect of angiodysplasias on QoL. Therefore, we aim to evaluate QoL and fatigue in angiodysplasia patients. We performed a cross-sectional patient-reported outcome study. We included patients with endoscopy proven angiodysplasias and measured QoL with Short Form-36 and level of fatigue using Multi Fatigue Inventory-20. We distinguished three subgroups of patients according to disease severity: 1 with treatment for angiodysplasias, 2 without treatment for angiodysplasias and 3 without recent hospital visits. The primary outcome was the physical component summary (PCS score on the SF-36. Multivariate regression analysis were performed to correct for differences at baseline. A total of 144 patients completed the questionnaires (response rate = 62%; mean age 68 years; 65% men. Angiodysplasia patients have a significant lower PCS compared to the age-matched general population (respectively 41.0 vs. 43.3, p = 0.01. Disease severity is independently associated with a negative outcome on QoL (ß -4.6, 95% CI -7.8--1.3. Similarly patients score lower on multiple QoL subdomains, i.e. role limitations due to physical health problems (40.8 vs. 44.0, p<0.01, general health (39.7 vs. 47.3, p<0.01. Angiodysplasia patients are more fatigued compared to the general population (male 56.1 vs. 48.5, p<0.01, female 59.2 vs. 51.5, p = 0.01. In conclusion, angiodysplasias are independently associated with clinically significant impairments in multiple domains of health-related QoL, especially in measures of functional limitation.

    Background: Disability is not just a health problem or attribute of individuals, but it reflects the problems individuals experience in their interaction with society and physical movements. Disabled persons remain neglected part of society and they also experience various barriers due to restriction of participation. Objectives: The aim was to assess the quality of life (QOL) of physically disabled persons, the impact of physical disability on activities of daily living (ADL) and to study the awareness about laws and facilities available for disabled persons. Materials and Methods: A cross-sectional community based study was conducted among 130 physical disabled persons who were selected using convenience sampling technique. The WHO BREF scale was used to assess QOL, while assessment of ADL was done using Barthel Index. Socio-demographic assessment was done using Udai Pareek scale. SPSS version 15.0 was used to analyze data. Categorical variables were expressed as frequencies and percentages. As per guidelines physical, psychological, social, and environmental domain scores for WHO BREF scale were calculated. Results: Among the study participants, 36.2% had a disability from birth that is, congenital. The second common cause of disability was found to be postpolio residual paralysis as it was found among 26.2% respondents. Other causes found were stroke/paralysis and accidents, in 19.2% and 18.5% respondents, respectively. Activities such as transfer, mobility, and stair climbing showed greater impact of physical disability. It was found that 11.5% respondents required help in one of the ADL. QOL score was found to be low under the psychological domain reflecting on negative feelings, bodily image, appearance, spirituality, and self-esteem of respondents. Conclusion: Physical disability had affected social participation as well as marriage of the respondents. However, it was found that very few of them are aware about facilities provided under persons with

    Full Text Available The lifetime of the pipeline, which undergoes trenchless repair by pulling and then fixing various types of internal protective coatings inside, is determined by the strength characteristics of the two-layer structure “old pipeline + internal protective coating”. Hydraulic parameters of internal protective coatings, such as surface roughness and degree of hydrophobicity (water repellency, can play a role in prolonging the life of the repaired pipeline. With a high degree of hydrophobicity of the protective coating, the contact of the transported liquid with the walls of the pipeline during its operation in the non-pressure regime decreases, which leads to a decrease in the negative impact on the walls, in particular, their attrition, interaction with the specific structure of the coating material, which in turn reduces the energy costs when transporting water. Given article deals with a mathematical description of the interaction of the surface structure (with its inherent wetting ability and the transported liquid in a mini-stream created on an inclined open chute imitating the inner surface of a pressureless pipeline. The theoretical positions and methodology for calculating the degree of hydrophobicity are based on research conducted on the basis of frontal and coaxial (along the flow digital photo and video. T

    Understanding how male nursing students alleviate life stress during their academic career is conducive to their development as successful nursing professionals. This study was designed to understand the personality traits, social support, and life stresses of male nursing students. The respective influences of personality traits and social support on life stress were also explored. The study used a cross-sectional research design. A college in central Taiwan was targeted as the site for data collection. A total of 158 questionnaires were dispatched, with 145 valid copies returned (valid response rate = 91.7%). Structured questionnaires were designed to collect data on participant demographics, personality traits, social support, and life stress. Statistical methods such as descriptive statistics, one-way analysis of variance, and multiple regression analysis were applied to data analysis. Major findings of this study revealed that (a) in general, the personality traits, social support, and life stress of male nursing students scored in the medium to high range. Participants reported encountering more stress from learning and life goals than from interpersonal stress. (b) Male nursing student demographic variables (e.g., parent [father and mother considered separately] education level) and the personality traits of conscientiousness and family support, respectively, were found to impact significantly on participant life stress perceptions. And (c) the only significant predictors of life stress were support from family and education level of participant fathers and mothers, accounting for about 23.7% of variability. It is suggested that nursing students in each year of their academic career should be exposed to courses geared to reduce the life stress perceptions (especially in the areas of learning and career development) of male nursing students. Increased family support is an effective way to decrease male nursing student life stress. This study could be a

    Full Text Available The main objective of this study was to identify the risk factors of dyslipidemia and measure its impact on patients’ quality of life (QOL. Secondary objectives were to determine the percentage of dyslipidemia and assess the predictive factors affecting patients’ QOL. A cross-sectional study was conducted in a sample of Lebanese population. A standardized questionnaire was developed to assess the QOL using the Short form-36 (SF-36 score. A total of 452 individuals were interviewed, of which 59.5% were females. The mean age was 43.3 ± 15.6 years, and 24.8% had dyslipidemia. The results show a lower overall QOL score among dyslipidemic patients compared with controls (57.9% and 76.5%, respectively; p < 0.001.

    Transgender women are exposed to stressful situations such as gender transition and transition-related discrimination because of their limited acceptance by the general population and inadequate government-supplied resources, which can compromise their quality of life (QOL). However, there is a paucity of research on the QOL of transgender women from China. To assess the QOL of transgender women from China and explore its associated factors. A cross-sectional study was performed by convenience sampling in Shenyang, China from January 2014 to July 2014. This sample consisted of 209 transgender women. The women were interviewed face-to-face to assess their QOL and related factors using the 36-item Short-Form Health Survey, the Adult Dispositional (Trait) Hope Scale, and the EGO Resilience Scale. Response scores were calculated based on a questionnaire design. Hierarchical multiple regression analysis was performed to explore factors associated with QOL. Transgender women who used hormone therapy reported significantly lower levels of the physical component summary (PCS) and the mental component summary (MCS) compared with those who did not (P discrimination from friends, knowledge of HIV prevention, hope, and resilience. Educational level and being chased or insulted by law enforcement officials were negatively associated with the MCS, whereas not using hormone therapy, having no regular partners or casual partners, less discrimination from friends, less social discrimination, knowledge of HIV prevention, and hope were positively associated with the MCS. Chinese transgender women reported high levels of physical QOL but low levels of mental QOL. Their mental QOL was more pronounced than their physical QOL. Transition status and sexual partnership played the most important roles in physical and mental health. Furthermore, mental QOL was best predicted by assessing positive capabilities, such as levels of hope. Future interventions should focus on recognizing

    To analyze the Health related Quality of Life (HRQoL) and physical function in rheumatoid arthritis (RA) patients and compare it with the general population. We also intended to analyze about disease activity influence in HRQoL and functional capacity, as well as determine potential determinants for these outcomes. A cross-sectional study was conducted in RA patients from a university hospital of Portugal. We obtained Short Form 36, EuroQoL 5D, health assessment questionnaire, visual analog scale for pain and patient's assessment of disease activity. Comparisons between SF-36 and EQ-5D values with our population reference values were conducted using the Mann-Whitney test. Data were compared in different levels of disease activity, using Kruskal Wallis test and Fisher's exact test. A multiple regression analysis was conducted to identify the potential determinants of outcomes. RA sample showed significantly lower values than the portuguese general population on physical summary measure of SF-36 (median=32 vs. 50, p<0.001) and EQ-5D (median=0.620 vs. 0.758 respectively; p<0.001). Lower disease activity levels had better PROs and this was true even when compared patients achieving remission with those in low disease activity. The HAQ (r 2 =67%), VAS-P (r 2 =62%) and VAS-DA (r 2 =58%) were the variables that strongly related to SF-36. Considering HAQ, the strongest relation was found with VAS-P, VAS-DA and age (r 2 =60%, 61% and 33%, respectively). Multiple regression analysis identified HAQ, VAS-P and educational status as determinants of the HRQoL; age, female gender, employment, VAS-P and VAS-DA as determinants of physical function. Impairment of HRQoL in RA patients is enormous. We found significant differences between different levels of disease activity, showing higher HRQoL and functional capacity at lower disease activity levels.

    Life orientation among the nursing home elders would differ from those of community-dwelling elders due to the different living environment, but may have greater differences in gender. This study was designed to investigate the positive life orientation and explore the potential risk factors including gender disparities among nursing home elders in China. This cross-sectional study was conducted in Northeast China. Two steps cluster sampling procedure were chosen. Basic activities of daily living (BADL) and instrumental activities of daily living (IADL) systems were used to estimate the functional status. Positive life orientation was measured using the six-question life orientation scale (LOS). 2512 nursing home elders were enrolled in the study. The mean age of the participants was 73.14±6.746years. Of the 1308 men and 1204 women, 14.9% had a positive life orientation in women and 16.1% in men. Higher level of education, independent in BADL and IADL were related to positive life orientation both in men and women. Age and BMI were also found to be significantly associated with positive life orientation in men (OR=0.587, 1.132, respectively). For women, the influence of income and vision on positive life orientation was also significant (OR=1.967, 1.926, respectively). The positive life orientation was higher in men than women. The gender-specific differences contribute to take more effective measures to improve the positive life orientation. Copyright © 2017 Elsevier B.V. All rights reserved.

    It has been shown that frailty is associated with low levels of well-being and life satisfaction. Further exploration is needed, however, to better understand which components constitute life satisfaction for frail older people and how satisfaction is related to other life circumstances. The aim of this study was to examine relationships between frail older people's life satisfaction and their socioeconomic conditions, social networks, and health-related conditions. A cross-sectional study was conducted (n=179). A logistic regression analysis was performed, including life satisfaction as the dependent variable and 12 items as independent variables. Four of the independent variables made statistically significant contributions: financial situation (OR 3.53), social contacts (OR 2.44), risk of depression (OR 2.26), and self-rated health (OR 2.79). This study demonstrates that financial situation, self-rated health conditions and social networks are important components for frail older people's life satisfaction. Health and social care professionals and policy makers should consider this knowledge in the care and service for frail older people; and actions that benefit life satisfaction - such as social support - should be promoted.

    Family is a major determinant of children's and adolescents' eating behavior. The objectives of the present study were to assess diet quality, eating habits, satisfaction with life, family life, and food-related life in mother-father-adolescent triads, and to identify profiles of families according to family members' diet quality. Questionnaires were administered to a sample of 300 two-parent families with one child over the age of 10 in the city of Temuco (Chile), including the Adapted Healthy Eating Index (AHEI), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFoL) scale, Satisfaction with Family Life (SWFaL) scales, and questions relating to their eating habits. Positive relationships were found between the diet quality of the family members, particularly between mothers and adolescents. Three family profiles with different diet qualities were identified: "families with an unhealthy diet" (39.3%), "families in which mothers and adolescents have healthy diets, but the fathers' diets require changes" (14.3%), and "families that require changes in their diet" (46.4%). These findings stress the key role of mothers in determining family diet quality and suggest a positive relationship between diet quality and satisfaction with life.

    The modern psychiatric view of schizophrenia spectrum disorders and their treatment has led to an increasing focus on coping strategies and the quality of life of these patients. In the present study, the authors examined the relationship between demographic data, the severity of symptoms, coping strategies, and the quality of life in psychotic patients. It is important to study the inner experience and striving of these individuals as it has been linked to their well-being and treatment adherence. Psychiatric outpatients who met International Classification of Diseases, Tenth Revision criteria for a psychotic disorder (schizophrenia, schizoaffective disorder, or delusional disorder) were recruited in the study. Questionnaires measuring the coping strategies (The Stress Coping Style Questionnaire [SVF-78]), the quality of life (Quality of Life Satisfaction and Enjoyment Questionnaire [Q-LES-Q]), and symptom severity (objective and subjective Clinical Global Impression - objCGI; subjCGI) were assessed. The data were analyzed using one-way analysis of variance, Mann-Whitney U test, Pearson and Spearman correlation coefficients, and multiple regression analysis. A total of 109 psychotic patients were included in the study. The quality of life was significantly related to both the positive and negative coping strategies. The severity of disorder was highly negatively correlated with the quality of life score. The results of multiple stepwise regression analysis using the quality of life as a dependent variable showed that symptom severity (subjCGI, difference between subjCGI, and objCGI), negative coping strategies, positive coping strategies, and the difference between positive and negative coping strategies explain more than half variance. Our study suggests the importance of utilizing the positive coping strategies in improving the quality of life in patients with psychotic disorders.

    Carboxymethyl cellulose (CMC) coatings alone and in combination with gamma irradiation was tested for maintaining the storage quality, inhibiting fungal incidence and extending shelf-life of cherry fruit. Two commercial cherry varieties viz. Misri and Double after harvest at commercial maturity were coated with CMC at levels 0.5-1.0 % w/v and gamma irradiated at 1.2 kGy. The treated fruit including control was stored under ambient (temperature 25 ± 2 °C, RH 70 %) and refrigerated (temperature 3 ± 1 °C, RH 80 %) conditions for evaluation of various physico-chemical parameters. Fruits were evaluated after every 3 and 7 days under ambient and refrigerated conditions. CMC coating alone at levels 0.5 and 0.75 % w/v was not found effective with respect to mold growth inhibition under either of the two conditions. Individual treatment of CMC coating at 1.0 % w/v and 1.2 kGy irradiation proved helpful in delaying the onset of mold growth up to 5 and 8 days of ambient storage. During post-refrigerated storage at 25 ± 2 °C, RH 70 %, irradiation alone at 1.2 kGy gave further 4 days extension in shelf-life of cherry varieties following 28 days of refrigeration. All combinatory treatments of CMC coating and irradiation proved beneficial in maintaining the storage quality as well as delaying the decaying of cherry fruit during post-refrigerated storage at 25 ± 2 °C, RH 70 % but, combination of CMC at 1.0 % w/v and 1.2 kGy irradiation was found significantly ( p  ≤ 0.05) superior to all other treatments in maintaining the storage quality and delaying the decaying of cherry fruit. The above combinatory treatment besides maintaining storage quality resulted in extension of 6 days in shelf life of cherry varieties during post-refrigerated storage at 25 ± 2 °C, RH 80 % following 28 days of refrigeration.

    Psoriasis is a common, long-term skin disease associated with high levels of psychological distress and a considerable adverse impact on life. The effects of psoriasis, beyond skin affliction, are seldom recognized and often undertreated. The aim of the study is to evaluate the quality of life, anxiety and depression, self-esteem and loneliness in patients with psoriasis. Eighty-four patients with psoriasis were enrolled in the study. The quality of life, depression and anxiety, loneliness and self-esteem of the patient were assessed using the Dermatology Life Quality Index, Hospital Anxiety and Depression Scale, the UCLA loneliness Scale (UCLA-Version 3) and Rosenberg's Self-esteem Scale, respectively. The Dermatology Quality of Life Index score among psoriasis patients was 12.61 ± 4.88. They had statistically significantly higher scores according to the Hospital Anxiety and Depression Scale -anxiety subscale (p=0.032)-compared with healthy volunteers. Moreover, a statistically significant difference was found between the two groups concerning the UCLA-scale (p=0.033) and RSES-scale (psocial aspects of the condition, as is the case for systemic, long-term conditions.

    Full Text Available Background. Chronic obstructive pulmonary disease (COPD is gaining an importance over the world, and its effect on quality of life is better grasped. Our objective was to use the Clinical COPD Questionnaire (CCQ to describe the respiratory quality of life in the Lebanese population, stressing on differences between smokers and nonsmokers. Methods. Using data from a cross-sectional national study, we checked the construct validity and reliability of the CCQ. Factors and items correlation with postbronchodilator FEV1/FVC were reported, in addition to factors and scale association with COPD and its severity. We then conducted a multiple regression to find predictors of quality of life. Results. The CCQ demonstrated excellent psychometric properties, with adequacy to the sample and high consistency. Smokers had a decreased respiratory quality of life versus nonsmokers, independently of their respiratory disease status and severity. This finding was confirmed in COPD individuals, where several environmental factors, lower education, and cumulative smoking of cigarette and of waterpipe were found to be independent predictors of a lower quality of life, after adjusting for COPD severity. Conclusions. Smoking decreases the respiratory quality of life of Lebanese adults; this issue has to be further emphasized during smoking cessation and patients’ education.

    In this cross-sectional study, we analyzed the relationship between resilience, cardiorespiratory fitness, and mental health-related quality of life, and examined whether resilience acts as a mediator between the latter two. The study included 770 university students, aged 18-30 years, from Cuenca, Spain. Anthropometric, sociodemographic, cardiorespiratory fitness (20 m shuttle run test), biochemical parameters, resilience, and mental health-related quality of life measurements were analyzed. The results showed that mental health-related quality-of-life values were significantly higher in students who had good cardiorespiratory fitness and a high level of resilience. Moreover, resilience acted as a partial mediator between cardiorespiratory fitness and mental health-related quality of life at 33.79%. Therefore, in young adults, resilience mediates the relationship between cardiorespiratory fitness and mental health-related quality of life. These findings should be taken into account by nurses and other public health professionals, because in addition to the development of physical activity interventions to improve mental health-related quality of life, it is necessary to implement measures that increase resilience to achieve mental wellness. © 2017 John Wiley & Sons Australia, Ltd.

    Social capital has been recognized as a major social determinant of health, but less attention has been given to social capital of persons with musculoskeletal impairments. The present study aimed to explore the associations between social capital and life satisfaction of persons with musculoskeletal impairments in Hanoi, Vietnam. A cross-sectional study was conducted in Hanoi, Vietnam. From June to July 2008, we collected data from 136 persons with musculoskeletal impairments who belonged to disabled people's groups. Social capital was measured using a short version of the Adapted Social Capital Assessment Tool that included group membership, support from groups, support from individuals, citizenship activities, and cognitive social capital. Life satisfaction was measured using the Satisfaction with Life Scale. As possible confounding factors, we measured socio-economic factors and disability-related factors such as activities of daily living. After controlling for confounding effects, group membership remained significantly associated with the level of life satisfaction reported by the persons with musculoskeletal impairments. In particular, being an active member of two or more groups was associated with higher life satisfaction. In contrast, other components of social capital such as citizenship activities and cognitive social capital were not significant in the multiple regression analysis of this study. The findings suggest the importance of considering an active participation in multiple groups toward the enhancement of the life satisfaction among persons with musculoskeletal impairments. To encourage persons with musculoskeletal impairments to have multiple active memberships, their access to groups should be facilitated and enhanced.

    Facebook is one of the most popular social networking sites. The present paper examines the relations between fear of missing out, narcissism, Facebook intrusion, and life satisfaction. We hypothesized that the fear of missing out and narcissism would play a significant role in Facebook intrusion. The participants in the study were 360 Polish users of Facebook. We administered the Facebook Intrusion Scale, the Fear of Missing Out Scale, the Narcissistic Personality Inventory, and the Satisfaction with Life Scale. The results showed that a high level of fear of missing out and high narcissism are predictors of Facebook intrusion, while a low level of fear of missing out and high narcissism are related to satisfaction with life. Our findings provide a more comprehensive picture of the predictors of Facebook intrusion and reveal interesting patterns. Copyright © 2017 Elsevier B.V. All rights reserved.

    End-stage renal disease is a complex, progressive and debilitating illness that affects patients' quality of life, physical and mental health, well-being, social functioning and emotional health. A cross-sectional survey was carried out in renal dialysis centres in Scotland to assess patients' health status and the impact of haemodialysis treatment on quality of life and well-being. Participants scored considerably lower than the UK general population in all domains of health-related quality of life, although mental health components were nearer to general population norms than physical health components. However, nearly half of the participants achieved a score on a general well-being questionnaire that was indicative of stress and anxiety. Increasing age was associated with better overall mental health but worse physical functioning. Increasing levels of hope and support were associated with improved general well-being. © 2013 Wiley Publishing Asia Pty Ltd.

    Over the last few decades, an increasing number of studies have examined quality of life in patients with chronic schizophrenia. However, little research has addressed the relationship between lifestyles that promote health and quality of life issues in these patients. The aim of this study was to investigate the relationships between lifestyles that promote health and quality of life in patients with chronic schizophrenia. A cross-sectional study design was used. The study was conducted at 10 hospital-based psychiatric rehabilitation units in northern Taiwan. In total, 357 participants completed the World Health Organization Quality of Life-BREF and the Health-Promoting Lifestyle Profile. This study examined the relationships among the six domains of the Health-Promoting Lifestyle Profile and the four domains of the Quality of Life-BREF using canonical correlation analysis. Data collection occurred between April 2013 and April 2014. The results of the canonical correlation analysis showed that the Health-Promoting Lifestyle Profile domains of nutrition, health responsibility, self-actualization, interpersonal support, exercise, and stress management were significantly related to the Quality of Life-BREF results, specifically in the physical, psychological, and social relationships and environment domains. Two canonical correlations were identified (the canonical correlation coefficients were .622 and .317), which showed that 38.6% of the variance in lifestyles that promote health and quality of life was shared. The results of this study may be useful to practitioners who are responsible for lifestyles that promote health and quality of life issues in patients with chronic schizophrenia.

    Full Text Available Abstract Background Quality of life differs for different people in different situations and is related to one's self-satisfaction with life. Considering the role of women in family and social health and the specific cultural characteristics of our province, we aimed to compare the quality of life of employed women with housewives in Zahedan, Iran. Methods This cross-sectional study was carried out during 2009–2010 in Zahedan, Iran. The sample consisted of 110 housewives and 110 employed women selected randomly from ten health care centers. Health-related quality of life was assessed using the SF-36. Analysis of covariance (ANCOVA was used to compare quality of life in housewives and employed women while controlling for age, education and income. Results The mean (±SD age of participants was 33.87± 8.95 years. Eighty-eight women (40% had a university degree with a mean (±SD official education of 10.8 (±4.9 years. The results indicated that employed women scored higher than housewives in all measures except for physical functioning. The differences were found to be remarkable for vitality, mental health and role emotional. However, after controlling for age, education and family income, none of differences reached significant level. Conclusion After controlling for potential confounders, the findings from this study indicated that there were no significant differences in quality of life between employed women and housewives. However, employed women scored higher on the SF-36, especially on the role emotional, vitality, and mental health. The findings suggest that associations exist between some aspects of health-related quality of life and employment. Indeed improving health-related quality of life among housewives seems essential.

    To analyze perceptions of health-related quality of life and associated factors in populations from the Manaus Metropolitan Region. We conducted a population-based cross-sectional study from May to August 2015. Adults aged 18 years and older were selected using probabilistic three-phase cluster sampling and stratified by sex and age, based on official estimates. Quality of life data were collected using the European Quality of Life 5-Dimensions 3-Levels (EQ-5D-3L) along with socioeconomic, demographic, and health perception data. Utility scores were calculated using the Brazilian version of the EQ-5D-3L. Descriptive statistics were derived, and a multivariate Tobit regression model with correction for complex sampling was performed to identify the variables that influence utility levels. A total of 4001 participants were included. The average utility score was 0.886 (95% confidence interval [CI]: 0.881-0.890) with significant differences according to living area (the capital (0.882 ± 0.144) or inner cities (0.908 ± 0.122; p quality of life than women (β = 0.041, p quality of life compared with being formally employed (β = 0.031, p = 0.037). The poorest people had a lower quality of life than the richest people (β = -0.118, p quality of life in the Manaus Metropolitan Region was high, as expected for the general population, and was higher among individuals who lived in the inner cities, men and those in higher social classes. Gender discrepancies and differences in quality of life between the capital and inner cities should be further investigated.

    The aim of this study was to explore the quality of life, self-stigma, personality traits, and hope in patients with schizophrenia spectrum disorders. A total of 52 outpatients participated in this cross-sectional study. The attending psychiatrist assessed each patient with Mini International Neuropsychiatric Interview (MINI). The patients then completed Quality of Life Satisfaction and Enjoyment Questionnaire (Q-LES-Q), Internalized Stigma of Mental Illness (ISMI) Scale, Temperament and Character Inventory - Revised (TCI-R), Adult Dispositional Hope Scale (ADHS), Drug Attitude Inventory 10 (DAI-10), and Liebowitz Social Anxiety Scale (LSAS)-Self-report. The psychiatrist evaluated Clinical Global Impression Severity - the objective version (objCGI-S), and the patients completed the Clinical Global Impression Severity - the subjective version (subjCGI-S). Each participant also completed Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI). The quality of life was significantly higher in employed patients and individuals with higher hope, self-directedness (SD), and persistence (PS). The quality of life was lower among patients with higher number of psychiatric hospitalizations, those with higher severity of the disorder, and individuals who were taking higher doses of antipsychotics. Patients with more pronounced symptoms of depression, anxiety, and social anxiety had a lower quality of life. Finally, the quality of life was lower among individuals with higher harm avoidance (HA) and self-stigmatization (ISMI). Backward stepwise regression was applied to identify the most significant factors connected to self-stigma. The regression analysis showed that occupation, level of depression (BDI-II), attitude to using medication (DAI-10), social anxiety (LSAS), and antipsychotic index were the most relevant factors associated with lower quality of life. Detection of the quality of life in the context of personality traits, hope, self-stigma, and

    Full Text Available Background: Unpredictable spells of epileptic seizures would result in embarrassment in society and have some negative impact on the patients’ social activities. The aim of this study was to show the perceived impact of epilepsy by patients on different aspect of their social activities including occupation, marriage and education.Materials and Methods: We studied 179 epileptic patients age 16 years and over with face to face interview. Nine domains including relation to spouses, relation to family members, social life, general health, interpersonal communications and friendships, feelings about success, hope for future, ordinary life and cope with others were considered.Results: One hundred and seven men and 72 women were studied. Nearly 78% of the patients had generalized tonic-clonic seizures. More than half of the patients believed that epilepsy had affected their social life and activities. General health was negatively affected by this disease more than any other item; this may be due to uncontrolled spells or taking medications. About 15.5% of married and 39% of the single patients considered epilepsy as an obstacle to marry with their ideal spouses and more than half of the employed persons considered epilepsy as an obstacle for their job promotions.Conclusion: Epilepsy frequently impact on several aspects of life. The disease negatively affects social lives and activities, overall health, feelings about self, ability to work in paid employments, relationship with spouses, friends, and other family members, future plans, standards of living and ambitions of epileptic patients. Decreasing such impacts should be considered as an important part of treatment and proper management can certainly increase various aspects of life in these patients.

    Vitiligo is a multi-factorial pigmentary skin disorder. Recently, the importance of emotional and psychological issues is proposed in incidence, progression, relapse and remission of vitiligo. There are limited studies conducted in developing countries, which assess life quality of patients with vitiligo. The aim of this study was the application and evaluation of a disease-specific quality of life index in Iranian patients, for the first time. This cross-sectional biphasic study was conducted on 25 patients as a pilot and another 173 patients as the main study group, in Razi Hospital, Tehran, Iran, 2013-2014. Persian version of Vitiligo Quality of Life index (VitiQoL) was developed with backward-forward method. Based on the pilot study, the validity and reliability were assessed. The Vitiligo Area and Score Index (VASI), VitiQoL, and their relationship, demographic and clinical characteristic of patients were measured. The Mean and standard deviation of the VitiQoL score was 30.5 ± 14.5 (range 0-60 in Persian version). There was a significant relationship between VASI score and VitiQoL (p = 0.015, r = 0.187). Confirmatory factor analysis revealed three important factors within VitiQoL: participation limitation, stigma, and behavior. In subscale analysis based on behavior factor, female patients had poorer quality of life (p = 0.02). Concomitant psychiatric problems, e.g. anxiety and depression, were not associated with QOL; however, they were near to being meaningful (p = 0.06, r = 0.14). VitiQoL is a valid index in estimating life quality of vitiligo patients and has proper relation to disease severity. Focusing on patient's life quality is an important entity in the management of vitiligo patients; relevant supportive group-based consultations and therapies are also important arms when approaching vitiligo.

    The relationship of demographic factors and negative life events to the mental health of mainland Chinese school students has not been fully explored. Assess the prevalence of different types of life stressors among secondary school students and identify the demographic characteristics and types of life events that are most closely associated with perceived psychological difficulties in these students. This cross-sectional study administered two self-completion questionnaires to a stratified random cluster sample of 1818 students from four secondary schools in two districts of Shanghai: the Strengths and Difficulties Questionnaire (SDQ) and an abbreviated version of the Adolescent Self-rating Life Events Checklist (ASLEC) that assesses 11 negative life events. Academic stress (74%), criticism from others (66%), family conflict (29%) and peer bullying & discrimination or interpersonal conflict (26%) were the most frequently reported negative life events, but their prevalence varied significantly by gender, type of school and urban versus rural residence. Similarly the level of reported psychological stress associated with life events, the total perceived psychological difficulty, and the level of pro-social behavior in the students varied significantly between different groups of students. Multivariate linear regression analysis identified the following independent predictors of high perceived psychological difficulty in the prior 6 months (in order of importance): high total stress score from negative life events in the prior year, experiencing peer bullying & discrimination or interpersonal conflict, not experiencing the death of a family member, male gender, attending a school in a rural district, and not suffering from a major disease or physical impairment. The independent predictors of a high level of pro-social behavior were high total stress score from negative life events, attending an urban school, female gender, attending a regular-tier school (vs. a high

    There is a global increase in migrant workers. In Singapore, there are over 230,000 migrant domestic workers (MDWs). Female MDWs may experience high levels of stress and social isolation, which may negatively impact on their health and quality of life. There have also been documented cases of abuse and exploitation. However, there is a lack of empirical research with this population. This study aimed to investigate factors impacting on the health and quality of life of female MDWs in Singapore, including socio-demographic and job related characteristics, stress, social isolation, and working management style. A cross-sectional survey was carried out with 182 female MDWs in Singapore. The survey examined health and quality of life (WHOQoL-Bréf), social connectedness (the Friendship Scale), and preferred and experienced working management style (the Theory X and Theory Y Questionnaire). Descriptive analyses were carried out in addition to ANOVA, t-tests, and chi-square tests, followed by a multivariate analysis using linear regression. Participants were found to have good overall quality of life and satisfaction with health. Age and working experience were found to be significantly (p life and three domains (psychological, social, and environmental health). Agreement between experienced and preferred working management style was also found to be associated with higher quality of life scores (with the exception of the social relationships domain). Though women reported relatively good overall quality of life, more than half of participants reported feeling stressed. In addition, nearly 20% of participants reported being isolated or very isolated. Stress was identified to be associated with isolation. In the multivariate analysis, stress was found to contribute to worse quality of life in all domains except social relationships, after adjusting for confounders. Social connectedness was positively associated with all domains of quality of life, and agreement of

Using PedsQL questionnaire, we analyzed the physical, emotional and social component of the quality of life of adolescents, school functioning and overall assessment score of the quality of life. The attitude to reading was determined by the results of the answers to questions about the love of reading (yes/no and the number of read books.Results: The study included 2,947 high school students, in which 2,473 (83.9% adolescents indicated their attitude toward reading. It has been shown that students who enjoy reading (42.2% have a lower assessment score of the quality of life on the scale of «emotional functioning» (66 ± 17 and higher — on the scale of «school functioning» (69 ± 15 than their peers not liking to read (68 ± 16 and 66 ± 15, respectively; p < 0.001. The number of read books was associated with the quality of life assessment on the scale of «physical functioning» and «school functioning» as well as with the assessment of the social component of quality of life for girls.Conclusion: The studied factors («reading books» and «the number of read books» are related to the quality of life of adolescents that may be taken into account in the preparation of educational programs.

    The purpose of this study was to examine the incidence of psychological complaints and the relationship of these complaints with the quality of life (QOL) and accident- and patient-related factors among severely injured patients after the rehabilitation phase. Patients of 18 years or older with an injury severity score above 15 were included 15-53 months after their accident. Accident and patient characteristics were obtained from questionnaires and the trauma registry. Several questionnaires (Hospital Anxiety and Depression Scale, Impact of Events Scale, and Cognitive Failure Questionnaire) were used to determine the symptoms of psychological problems (anxiety or depression, post-traumatic stress disorder, or subjective cognitive complaints, respectively). The World Health Organization Quality of Life-Bref was used to determine QOL. A reference group of the Dutch general population was used for comparison of QOL scores. The participation rate was 62 % (n = 173). At the time of the study, 30.1 % (n = 52) of the investigated patients had psychological complaints. No relation between psychological complaints and somatic severity or type of injury was found. Patients who were employed before the accident or resumed working reported less psychological complaints. Use of any medication before the accident and treatment for pre-accidental psychological problems were positively related to psychological complaints afterwards. QOL of severely injured patients was impaired in comparison with the general Dutch population, but only for those with psychological complaints. Psychological complaints seem to be an important and underestimated factor for a decreased QOL among severely injured patients.

    Full Text Available Abstract Background Despite certain contradictions, an association has been identified between adherence to drug treatment and the quality of life in patients with type 2 diabetes. The contradictions observed emphasize the importance of using different methods to measure treatment adherence, or the association of psychological precursors of adherence with quality of life. For this reason, we have used an indirect method to measure adherence (pill count, as well as two adherence behaviour precursors (attitude and knowledge, to assess the association between adherence and the quality of life in type 2 diabetes patients. Methods A cross-sectional comparative study on a random sample of 238 type 2 diabetic patients was carried out over one year in four family medicine units of the Mexican Institute of Social Security (IMSS in Aguascalientes, Mexico. Treatment adherence was measured using the indirect method of pill count to assess adherence behaviour, obtaining information at two home visits. In the first we recorded the medicine prescribed and in the second, we counted the medicine remaining to determine the proportion of the medicine taken. We also assessed two adherence behaviour precursors: the patients' knowledge regarding their medical prescription measured through a structured questionnaire; and attitudes to treatment adherence using a Likert scale. Quality of life was measured through the WHOQOL-100 (the WHO Quality of Life questionnaire. Information concerning both knowledge and attitude was obtained through interviews with the patients. A multiple linear regression model was constructed to establish the relationship between each quality of life domain and the variables related to adherence, controlling for covariates. Results There was no association between quality of life and treatment adherence behaviour. However, the combination of strong knowledge and a positive attitude was associated with five of the six quality of life domains

    With the increasing prevalence of diabetes in patients aged over 75, the task of ensuring a good quality of life became even greater. This study aimed to evaluate quality of life of the very elderly (≥75 years) type 2 diabetic primary care patient, in an urban family practice setting. A cross sectional study was conducted. Quality of life (QoL) was assessed with the Portuguese version of EASY-Care. Descriptive and inferential analyses were performed. Eighty three elderly type 2 diabetics were included in the study, with a mean age of 80.9 ± 4.3 years old. Most were women, widowed or married, with low educational levels, living with family members in urban areas and presented medium/low incomes. Participants were diagnosed with diabetes for 11.2 ± 10.1 years. Most of them were treated with oral antidiabetic agents, presented complications of diabetes and had good glycemic control. Despite that, excess weight, uncontrolled blood pressure and poor lipid management were noticed. In general, the participants perceived a positive quality of life. The worst perceived domain was "mental health and well-being". Within the sociodemographic variables, gender, monthly income, and living arrangements interfered the most with the quality of life domains. Studied clinical variables affected quality of life very modestly. In an urban primary care setting, when treating very elderly type 2 diabetic patients, and despite good glycemic control, attention should be paid to the QoL of women, the low income diabetics, their living arrangements and thoroughly evaluate the mental health and well-being of these patients.

    Background Social capital has been recognized as a major social determinant of health, but less attention has been given to social capital of persons with musculoskeletal impairments. The present study aimed to explore the associations between social capital and life satisfaction of persons with musculoskeletal impairments in Hanoi, Vietnam. Methods A cross-sectional study was conducted in Hanoi, Vietnam. From June to July 2008, we collected data from 136 persons with musculoskeletal impairments who belonged to disabled people's groups. Social capital was measured using a short version of the Adapted Social Capital Assessment Tool that included group membership, support from groups, support from individuals, citizenship activities, and cognitive social capital. Life satisfaction was measured using the Satisfaction with Life Scale. As possible confounding factors, we measured socio-economic factors and disability-related factors such as activities of daily living. Results After controlling for confounding effects, group membership remained significantly associated with the level of life satisfaction reported by the persons with musculoskeletal impairments. In particular, being an active member of two or more groups was associated with higher life satisfaction. In contrast, other components of social capital such as citizenship activities and cognitive social capital were not significant in the multiple regression analysis of this study. Conclusions The findings suggest the importance of considering an active participation in multiple groups toward the enhancement of the life satisfaction among persons with musculoskeletal impairments. To encourage persons with musculoskeletal impairments to have multiple active memberships, their access to groups should be facilitated and enhanced. PMID:21457544

    The objective of this study was to identify the association between emotional distress and social support networks with quality of life in primary care patients. This was a cross-sectional study involving 1,466 patients in the cities of São Paulo and Rio de Janeiro, Brazil, in 2009/2010. The General Health Questionnaire, the Hospital Anxiety and Depression Scale and the brief version of the World Health Organization Quality of Life Instrument were used. The Social Support Network Index classified patients with the highest and lowest index as socially integrated or isolated. A bivariate analysis and four multiple linear regressions were conducted for each quality of life outcome. The means scores for the physical, psychological, social relations, and environment domains were, respectively, 64.7; 64.2; 68.5 and 49.1. In the multivariate analysis, the psychological domain was negatively associated with isolation, whereas the social relations and environment domains were positively associated with integration. Integration and isolation proved to be important factors for those in emotional distress as they minimize or maximize negative effects on quality of life.

    A decade ago, in the initial stage of genetic testing for familial hypercholesterolaemia (FH) in The Netherlands, it was reported that such screening decreased access to affordable life insurance for mutation carriers. In 2003, in order to improve access to insurance for FH mutation carriers, insurers agreed to underwrite according to a set of guidelines. In this cross-sectional study, we assessed whether access to insurance has improved since the advent of these guidelines. We approached 2825 subjects that had participated in the genetic testing for FH between 1998 and 2003. We compared unconditional acceptance rates before and after FH diagnosis and before and after the guidelines were issued by means of logistic regression analysis. Our study outcome pertains to 414 FH patients who applied for life insurance. Unconditional acceptance of a policy before DNA diagnosis and before the issue of guidelines occurred in 182 out of 255 (71%) cases, versus 27 out of 35 (77%) cases after DNA diagnosis, but before the issue of guidelines. De facto, 107 out of 124 (86%) patients received unconditional acceptance after DNA diagnosis and after the issue of guidelines (P for trend=0.002). Access to life insurance improved for FH patients after molecular diagnosis and it improved even further after the guidelines were issued. Therefore, we argue that limited access to life insurance on the basis of 'DNA discrimination' is no longer a valid argument against genetic cascade testing for FH, at least not in our country.

    Research has suggested that psychological stress is positively associated with asthma morbidity. One major source of stress in adulthood is one's occupation. However, to date, potential links of work stress with asthma control or asthma-specific quality of life have not been examined. We aimed to address this knowledge gap. In 2014/2015, we conducted a cross-sectional study among adults with asthma in Germany (n = 362). For the current analyses that sample was restricted to participants in employment and reporting to have never been diagnosed with chronic obstructive pulmonary disease (n = 94). Work stress was operationalized by the 16-item effort-reward-imbalance (ERI) questionnaire, which measures the subcomponents "effort", "reward" and "overcommitment." Participants further completed the Asthma Control Test and the Asthma Quality of Life Questionnaire-Sydney. Multivariable associations were quantified by linear regression and logistic regression. Effort, reward and their ratio (i.e. ERI ratio) did not show meaningful associations with asthma morbidity. By contrast, increasing levels of overcommitment were associated with poorer asthma control and worse quality of life in both linear regression (ß = -0.26, p = 0.01 and ß = 0.44, p life. Longitudinal studies with larger samples are needed to confirm our findings and to disentangle the potential causality of associations.

The work-related causes of musculoskeletal disorders (MSD are also well explored. And stress (at work has been found to be a consequence of WLC as well as a cause of MSD. But very little is known about a potential association between WLC and MSD and the possible mediating role of stress in this relationship. Methods Survey data collected in 2007 among the workforces of four large companies in Switzerland were used for this study. The study population covered 6091 employees. As the exposure variable and hypothesized risk factor for MSD, WLC was measured by using a 10-item scale based on an established 18-item scale on work-family conflict. The outcome variables used as indicators of MSD were (low back pain and neck/shoulder pain. Stress as the assumed intervening variable was assessed by a validated single-item measure of general stress perception. Correlation coefficients (r, standardized regression coefficients (β and multiple adjusted odds ratios (OR were calculated as measures of association. Results WLC was found to be quite strongly associated with MSD (β = .21. This association turned out to be substantially confounded by physical strain at work, workload and job autonomy and was considerably reduced but far from being completely eliminated after adjusting for general stress as another identified risk factor of MSD and a proven strong correlate of WLC (r = .44. A significant and relevant association still remained (β = .10 after having controlled for all considered covariates. This association could be fully attributed to only one direction of WLC, namely the work-to-life conflict. In subsequent analyses, a clear gradient between this WLC direction and both types of MSD was found, and proved to be consistent for both men and women.

    Full Text Available Abstract Background Comprehensive evidence exists regarding the discrepancy between children's reports and parents' by proxy reports on emotional and behavioural problems. However, little is yet known about factors influencing the extent to which child self- and parent by proxy reports differ in respect of child Quality of Life (QoL. The aim of the study was to investigate the degree of discrepancy between child and parent by proxy reports as measured by two different QoL instruments. Methods A representative Norwegian sample of 1997 school children aged 8–16 years, and their parents were studied using the Inventory of Life Quality (ILC and the 'Kinder Lebensqualität Fragebogen' (KINDL. Child and parent reports were compared by t-test, and correlations were calculated by Pearson product moment coefficient. Psychometric aspects were examined in regard to both translated QoL instruments (internal consistency by Cronbach's alpha and test-retest reliability by intraclass correlation coefficients. Results Parents evaluated the QoL of their children significantly more positively than did the children. Correlations between mother-child and father-child reports were significant (p Conclusion In the present general population sample, parents reported higher child QoL than did their children. Concordance between child and parent by proxy report was low to moderate. The level of agreement between mothers and fathers in regard to their child's QoL was moderate. No significant impact of parent and child gender in regard to agreement in ratings of child QoL was found. Both the child and parent versions of the Norwegian translations of the KINDL and ILC can be used in surveys of community populations, but in regard to the self-report of 9–10 years old children, only the KINDL total QoL scale or the ILC are recommended.

    The aim of this study was to understand better the quality of life (QOL) and illness perception in women with primary biliary cirrhosis (PBC) through a comparison with women having diabetes. One hundred and ninety-four women took part in this study: 130 with PBC, 64 with type 2 diabetes. They were administered the SF-12 to measure QOL and the Brief Illness Perception Questionnaire to assess representations of their illness. Analysis of covariance with bootstrapping was used to compare QOL and illness perception scores by controlling age and mean disease duration. Physical QOL was significantly worse for women with PBC than for women with diabetes. Women with PBC felt their disease would last longer and reported more symptoms and concerns related to their disease than women with diabetes. Significant differences were also observed for causes: women with PBC mainly reported autoimmune, emotional, unknown/unlucky and medical causes whereas women with diabetes reported mostly lifestyle and hereditary causes. Marginally significant differences were observed regarding consequences on daily life, feeling of control over the disease and emotional responses, which were shown to be worse in PBC. Mental QOL, treatment control and overall understanding of the disease was similar in both groups. This study shows that women with PBC have a worse QOL and somewhat different illness perception than women with diabetes. Further research could help understand PBC specificities better in order to improve patient care, especially if factors such as fatigue or rarity of the disease explain these results.

    Background Potentially modifiable lifestyle factors may influence cognitive health in later life and offer potential to reduce the risk of cognitive decline and dementia. The concept of cognitive reserve has been proposed as a mechanism to explain individual differences in rates of cognitive decline, but its potential role as a mediating pathway has seldom been explored using data from large epidemiological studies. We explored the mediating effect of cognitive reserve on the cross-sectional association between lifestyle factors and cognitive function in later life using data from a population-based cohort of healthy older people. Methods and findings We analysed data from 2,315 cognitively healthy participants aged 65 y and over in the Cognitive Function and Ageing Study Wales (CFAS-Wales) cohort collected in 2011–2013. Linear regression modelling was used to investigate the overall associations between five lifestyle factors—cognitive and social activity, physical activity, diet, alcohol consumption, and smoking—and cognition, adjusting for demographic factors and chronic conditions. Mediation analysis tested for indirect effects of the lifestyle factors on cognition via cognitive reserve. After controlling for age, gender, and the presence of chronic conditions, cognitive and social activity, physical activity, healthy diet, and light-to-moderate alcohol consumption were positively associated with cognitive function, together accounting for 20% (95% CI 17%–23%) of variance in cognitive test scores. Cognitive reserve was an important mediator of this association, with indirect effects via cognitive reserve contributing 21% (95% CI 15%–27%) of the overall effect on cognition. The main limitations of the study derive from the cross-sectional nature of the data and the challenges of accurately measuring the latent construct of cognitive reserve. Conclusions Cross-sectional associations support the view that enhancing cognitive reserve may benefit cognition

    The relationship between vitamin D and common mental disorders (CMDs) remains unclear. We aimed to determine if behaviours affecting vitamin D concentrations differ between individuals with or without CMDs and evaluate, cross-sectionally and prospectively, the extent to which the association between 25(OH)D and CMDs are explained by these behaviours. Data are from the 1958 British birth cohort (n = 7401). Behaviours were ascertained by questionnaire at age 45 years. CMDs (depression, anxiety, panic, phobia) were assessed using the Clinical Interview Schedule-Revised at 45 years and depression using Mental Health Inventory-5 at 50 years. Participants with CMDs at 45 years differed from others on some but not all vitamin D related behaviours. There were inverse, cross-sectional associations at 45 years of 25(OH)D with depression and panic, which persisted after adjustment for vitamin D related behaviours (OR = 0.57, 95% CI: 0.40,0.81 and OR = 0.33, 95% CI: 0.40,0.81, respectively). Association between 25(OH)D and subsequent (50 years) risk of depression was non-linear (p = 0.01), with lower risk for participants with 25(OH)D between 50 and 85 nmol/l compared with those with lower or higher concentrations. This study provides support for an association of low 25(OH)D concentrations with current and subsequent risk of depression in mid-adulthood.

    The effect of edible chitosan-cassava starch (CH-CS) coatings containing a mixture of Lippia gracilis Schauer genotypes (EOM) on the shelf life of guavas during storage at room temperature for 10 days was studied. Sixteen formulations were prepared with a range of chitosan and essential oil mixtures concentrations, and the in vitro antimicrobial activity was tested. Formulations containing 2.0% cassava starch, 2.0% chitosan and 1.0%, 2.0% or 3.0% EOM were most effective in inhibiting the growth of the majority of bacteria. The edible CH-CS coating and CH-CS with 1.0% (CH-CS-EOM1) or 3.0% EOM (CH-CS-EOM3) were added to guavas and the shelf life was evaluated. On the tenth day of storage, total aerobic mesophilic bacteria and mould and yeast counts were statistically lower (p<0.05) in the CH-CS-EOM1- or CH-CS-EOM3-coated fruits than CH-CS-coated fruits. In addition, fruits coated with CH-CS or CH-CS-EOM showed no significant changes of total soluble solids content, while CH-CS-EOM-coated fruits showed lower titratable acidity than CH-CS-coated fruits at the end of storage. CH-CS-EOM3-coated guavas showed lower a(∗) and b(∗) values and higher L(∗) and hue values than those with other coatings. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2013-01-01

    Background Previous findings suggest that stressful life events have a causal relationship with depressive symptoms. However, to date little is known concerning the contribution of the number and severity of recent stressful life events on the prevalence of depressive symptoms among university students. The aim of this study was to investigate the prevalence of depressive symptoms and its association with the number and the severity of self-reported stressful life events among university students in Cyprus. Methods A descriptive correlational design with cross sectional comparison was used. The CES-D scale was applied for the assessment of depressive symptoms and the LESS instrument for stressful life events. Both scales were completed anonymously and voluntarily by 1.500 students (response rate 85%). Results The prevalence of mild to moderate depressive symptoms [CES-D score between 16 and 21] and of clinically significant depressive symptoms [CES-D score ≥ 22] were 18.8% and 25.3% respectively. There were statistically significant differences in clinically significant depressive symptoms by gender, with higher rates among women (x2 = 8.53, df = 1, p = 0.003). Higher scores on the LESS scale were associated with more frequent reports of clinical depressive symptoms (x2 = 70.63, df = 4, p depressive symptoms (x2 = 40.06, df = 4, p  351, OR = 3.03 95% CI: 1.66, 5.39) were more likely to manifest clinical depressive symptoms. Conclusions The high frequency of occurrence of depressive symptoms among Cypriot university students, as well as the strong association with stressful life events, highlights the need for psychological empowerment strategies towards students by institutional counseling services.

    The aim of the study was to assess health-related quality of life (HR-QoL) in children with Turner syndrome in comparison with controls. We prospectively recruited 16 female girls with Turner syndrome (mean age 15.2±2.6 years) and 78 female controls (mean age 12.7±2.8 years) in randomly selected schools. We used the PedsQL, a generic HR-QoL questionnaire (self and parents' versions). Global HR-QoL scores in Turner syndrome were lower than controls for self-reports (respectively, 74.3±3.0 vs. 82.8±1.3, p=0.01) and parents' reports (62.7±3.8 vs. 80.1±1.7, pTurner syndrome, self-reported HR-QoL was impaired in school functioning (70.6±4.0 vs. 80.71±1.7, p=0.02), social functioning (78.2±4.0 vs. 90.4±1.8, pTurner syndrome, as in previously reported adult studies. In addition to medical treatment and routine clinical follow-up, female girls and teenagers with Turner syndrome should also be supported psychologically by social, educational and psychotherapeutic interventions that aim to address their self-esteem and emotional difficulties.

    Full Text Available Stuttering is a complex communication disorder that impedes the normal flow and pattern of speech, which is characterized by involuntary audible or inaudible pause, repetitions, prolongations, blocks, etc. Other than the core behaviors, people who stutter experience various other problems such as fear, anxiety, depression, shame, etc., which can in turn affect the quality of life (QOL. The purpose of this study is to develop a questionnaire in order to assess the QOL of people who stutter. A total of 30 participants aged between 18 and 30 years were enrolled for the study. Out of the stutterers included, 15 were employed and 15 were non-employed/students. The study was carried out in two phases. The first phase involved the development of a questionnaire based on literature search and available tests. The second phase involved administering the validated questionnaire on the participants. The questionnaire consisted of six domains targeting (1 speech-related fear and anxiety, (2 interpersonal and social relationships, (3 behavioral reaction to stuttering, (4 educational status, (5 employment and job opportunity, and (6 effect of speech therapy. For each item, response scales were organized (2—almost always, 1—sometime, 0—not at all. Developed questionnaire showed good content validity for all the domains and questions. The result of Cronbach's alpha for each domain indicates moderate internal consistency and excellent internal consistency for the overall questionnaire. Multiple domains were observed to be affected among adults who stutter, and the differences were not found to be significantly different as compared to the available QOL data from other cultural settings.

    Full Text Available BackgroundThere has been a shift in mental health services from an emphasis on treatment focused on reducing symptoms to a more holistic approach involving quality of life (QOL and overall well-being. Many psychosocial variables are associated with QOL but a parsimonious framework is needed to deepen our understanding about the contribution of psychosocial factors in influencing the QOL of Asian patients with schizophrenia in Singapore. The study aimed to address the current gap in literature by analysis of QOL using available predictors in Asian patients with schizophrenia in Singapore.Methods43 Singaporean patients diagnosed with schizophrenia were recruited at a large teaching hospital in Singapore from January to May 2010 and were invited to complete questionnaires. Of the sample, 65.1% were females, ages ranged from 18 to 65 (M = 44.60, SD = 12.19. Available variables were subjected to regression analysis.FindingsThe data were analyzed using SPSS Version 23 with the alpha level set at 0.05. The final model with five predictors was significant in predicting QOL. Positive Re-appraisal, Social Support, Avoidant Coping, Duration of Hospitalization, and Education accounted for 47.2% of the variance (Adjusted R2 = 40.0% in QOL, F (5, 37 = 6.60, p < 0.001. Those with post-secondary or higher education had higher QOL than those with secondary or lower education. Duration of hospitalization negatively predicted QOL.ConclusionThe findings were discussed in regards to clinical implications for informing interventions to enhance QOL in patients with schizophrenia.

    With current modalities, cure rates of retinoblastoma are high and hence the number of survivors is increasing. However, data on quality of life (QOL) are minimal. We analyzed QOL in 122 retinoblastoma survivors using the PedsQL(TM) 4.0 generic core scale. The self-reported questionnaire was filled by children of more than 5 years of age who had completed treatment for more than 12 months. The questionnaire consists of 23 questions on physical, social, emotional, and school domains on a scale from 0 to 4. This was converted to a scale from 0 to 100, where higher values represented better QOL. The QOL was compared with 50 siblings. Factors predicting the QOL were assessed. The median age of retinoblastoma survivors was 98 months (range 60-247) and 68% were males. Overall QOL was significantly poorer in retinoblastoma survivors as compared with the controls. The emotional health domain of QOL was significantly affected. Difficulties in maintaining friendships and competing were reported in the social health domain. The school health domain showed significantly higher absenteeism. However, the physical health domain, including household work, exercise, and self-care, was similar in both the groups. Lower age at diagnosis (≤ 18 months) predicted better QOL (P = 0.05), whereas age at assessment, sex, IRSS stage, and previous surgery and radiotherapy were not predictive of poor QOL. We found a significantly poorer QOL in retinoblastoma survivors with the psychosocial health domain being more affected than the physical domain. Age less than 18 months at diagnosis predicted better QOL. © 2015 Wiley Periodicals, Inc.

    Quality of marriage exerts a great effect on quality of life [QOL] and health outcomes. Few data are available on the effects of Crohn's disease [CD] on quality of marriage. We aimed to clarify whether and how CD affected the marital relationship. Web-based questionnaires were created including an ENRICH marital inventory, a general QOL survey [SF12], a short Inflammatory Bowel Disease Questionnaire [SIBDQ] and a modified Harvey-Bradshaw Index [HBI]. Married patients were enrolled through the outpatient registration system and diverse social media websites. Controls were subsequently enrolled and matched with the ratio of 1:1 through invitation emails and internet advertising. A total of 243 patients completed valid questionnaires and then 243 matched individuals were enrolled. Male patients were more affected, representing a significantly reduced total marital score. CD impaired the dimensions of idealistic distortion and marital satisfaction in both genders. There were correlations between quality of marriage, SF12, SIBDQ and HBI. Mental scale of SF12 correlated best with the marital relationship, indicating more significant involvement of mental adjustment. Multiple linear regression demonstrated that spouse's educational background, duration of marriage from disease onset, enteral nutrition, hospitalisation in past 12 months, and number of previous hospitalisations, independently impacted on quality of marriage. Certain aspects of the marital relationship were impaired in CD patients, especially in male subjects. In addition to medication, mental interventions should be given attention to improve the marriage of CD patients. Despite some novel findings in this study, this research orientation deserves more attention. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press.

    Full Text Available Introduction: The relationship of oral health (OH with the quality of life (QL is multidimensional; the extent to which oral disorders disrupt an individual′s normal function may affect health-related QL, particularly among children. The current study aimed to examine the relationship between clinical OH variables, psychological, social, and demographic factors with regard to OH-related QL (OHRQL in the children of Isfahan province, Iran. Materials and Methods: Data relevant to the characteristics, psychological, dental, and demographic factors of 336 children aged 11-15 were assessed. These characteristics included sociodemographic data, sense of coherence (SOC, self-esteem, and children′s health locus of control (HLC. The clinical variables that were implicated to be effective on the QL were assessed via an oral examination. The parameters assessed included caries, periodontal disease, malocclusion, and traumatic dental injuries. Finally, the data was analyzed using Statistical Package for the Social Sciences (SPSS software and P-value was set at 0.05. Results: The results indicate that oral disease, the extent of treatment-need, self-reported symptoms, and degree of dysfunction were influential in QL. Bivariate (Spearman and Pearson analysis showed that there was a relationship between decayed, missing, and filled teeth (DMFT and QL score (r = 0.4, P-value = 0.03 and gender and total self-esteem (r = 0.8, P-value = 0.009. Self-esteem and index of orthodontic treatment need (IOTN (P-value = 0.01, education level of the parents (P-value = 0.03, and overall health (P-value = 0.001 significantly influenced OHRQL. Conclusions: The findings of our study indicate that oral disease, the extent of treatment-need, self-reported symptoms, and degree of dysfunction were influential in the QL.

    The focus of this study was quality of life and mental health in elderly people living in the Bethlehem district. The aim of this study was to identify the most prevalent mental health problems and how they affect quality of life. This cross-sectional study was done in June and July, 2010. We recruited a convenience sample of elderly people (aged 65 years and older) living in the Bethlehem district of occupied Palestinian territory. Using a structured questionnaire, we assessed quality of life with the WHOQOL-BREF and current psychological status and distress with the Brief Symptom Inventor. Verbal consent form was obtained from all participants before their interview. 291 (97%) of 300 elderly people approached for this study completed the questionnaire. 101 (35%) participants described severe or very severe levels of somatisation. 39 (14%) participants reported severe or very severe obsessive compulsive symptoms, 27 (9%) complained of severe or very severe anxiety symptoms, and 37 (13%) had severe or very severe depression. 135 (46%) participants rated their quality of life as good or very good, but the physical health domain of the WHOQOL-BREF scale had the lowest scores (mean 50·9 [SD 21·4]) of all the domains. 103 (36%) participants perceived their physical health as being good or very good, whereas 95 (33%) participants rated their social life as good or very good. 117 (40%) participants were satisfied or very satisfied with their environment, and 119 (41%) participants evaluated their psychological health as good or very good. A stepwise regression analysis of variables indicated that an increase in psychological symptoms was independently associated with lack of education, living in a rural area, being economically dependent on others, and living with chronic disease. Poor quality of life was independently associated with increased age, lack of education, living in the home of sons, and being economically dependent on others. In view of the high prevalence

    To assess QoL of infertile Chinese women and determine the specific factors adversely affecting QoL for improving the care and treatment compliance of infertile women. We conducted a cross-sectional study on a randomized, demographically matched, controlled population of infertile married Chinese women to determine their demographic, menstrual, family stress, and infertility characteristics and then applied the World Health Organization QoL Instrument (WHOQOL-100) to determine which factors would be associated with significant QoL differences between infertile women and their demographically matched fertile controls. Infertile women showed lower QoL scores in the facets of spirituality/religion/personal beliefs, self-esteem, financial resources, and accessibility to and quality of health and social care, as well as increased pain and discomfort, while also experiencing positive QoL adjustments in terms of mobility, daily living activities, work capacity, sexual activity, freedom, physical safety, security, and transport. Married infertile Chinese women had significantly lower overall and comprehensive QoL scores, as well as higher anxiety scores, compared with fertile controls. Copyright © 2016.

    Full Text Available Objective: This descriptive and cross-sectional study was undertaken to determine the factors affecting quality of life (QOL in breast cancer patients. Methods: We collected data from 60 patients of carcinoma breast post modified radical mastectomy on radiotherapy in a tertiary care hospital. We included volunteered patients with a signed informed consent and at least 70 Karnofsky Performance Scale points. The data was gathered by interview technique using EORTC QLQ-C30 and QLQ-BR23 (Breast Cancer Module. Results: The mean age at presentation was 47.6 years (range 30-75 years.75% patients were of low socio-economic status and 63.3% belonged to rural areas. Younger Women in the age group of 30-39 years had faired worst on physical, social and emotional scores as compared to older women in the age group of 70-79 years. Other factors which affected Quality of Life of patients during treatment were stage of disease at presentation, performance score of the patients, socioeconomic status of disease at follow up. Conclusion: Age, Education status, Performance Score, Stage of disease at presentation and status of disease at last follow up are few factors which significantly affects QOL in Carcinoma breast patients though the treatment remains same. Advanced studies on individual quality of life factors affecting cancer would empower physicians for better personal care techniques and patients for easily overcoming the disease.

    The effect of composite edible films containing soy protein isolate (SPI) in combination with additives like hydroxypropyl methylcellulose (HPMC) and olive oil on 'Babughosha' pear ( Pyrus communis L.) stored at ambient temperature (28 ± 5 °C and 60 ± 10% RH) was evaluated using Response surface methodology (RSM). A total of 30 edible coating formulations comprising of SPI (2-6%, w/v), olive oil (0.7-1.1%, v/v), HPMC (0.1-0.5%, w/v) and potassium sorbate (0-0.4% w/v) were evaluated for optimizing the most suitable combination. Quality parameters like weight loss%, TSS, pH and titrable acidity of the stored pears were selected as response variables for optimization. The optimization procedure was carried out using RSM. It was observed that the response variables were mainly effected by concentration of SPI and olive oil in the formulation. Edible coating comprising of SPI 5%, HPMC 0.40%, olive oil 1% and potassium sorbate 0.22% was found to be most suitable combination for pear fruit with predicted values of response variables indicated as weight loss% 3.50, pH 3.41, TSS 11.13 and TA% 0.513.

    The essential oil of sweet orange, lemon, and key lime peel were analyzed for their antimicrobial activity. The antimicrobial activity of each citrus essential oil with different concentration was assessed using broth macro-dilution against Bacillus sp, Eschericia coli, Rhizopus stolonifer, and Botrytis sp which represented specific spoilage microorganism in tofu and fresh strawberry. Among all the citrus peel essential oils tested, lemon peel essential oil with 0.6% concentration showed significant activity as an antimicrobial agent against Escherichia coli and Bacillus sp. In other hand 1% of lemon peel essential oil is also considered to be the best concentration of inhibiting the Rhizopus Stolonifer and Botrytis sp. Lemon peel essential oil which has the highest antimicrobial activity was combined with two different kind of edible coating agents (cassava starch and sodium alginate) and was applied in both tofu and strawberry to observe whether it had possibility to decrease the degradation rate of tofu and strawberry. The addition of 0.6% and 1% lemon peel essential oil with each of edible coating agents was significantly able to reduce the degradation of tofu and fresh strawberry.

    Full Text Available Abstract Background Breastfeeding within the first hour of life is a potential mechanism for health promotion. The purpose of this study was to evaluate the prevalence of breastfeeding initiation within the first hour of life in Feira de Santana, Bahia, Brazil, between 2004 and 2005, and investigate the influence of maternal, child and prenatal factors on this practice. Methods This is a cross-sectional study extracted from the results of a contemporary cohort conducted in 10 maternity hospitals in the city of Feira de Santana, Bahia, Brazil. A group of 1,309 mother-child pairs was included in the study. Information about mother's and baby's characteristics, pregnancy, birth, and time of breastfeeding initiation was collected in the first 72 hours after delivery, through interview with mothers and hospital records. The data gathered were stored and analyzed using the SPSS 16.0 and R 8.0. The chi-square test and binary logistic regression analysis were used to examine the relationship between breastfeeding within the first hour and different variables. Results 47.1% of the mothers initiated breastfeeding within the first hour after birth. Early initiation of breastfeeding was associated with birth at full term pregnancy (adjusted Prevalence Ratio 1.43; 95% confidence interval 1.10 to 2.00, mothers who received prenatal guidance regarding the advantages of breastfeeding (aPR1.23; 95% CI 1.11 to 1.41 and vaginal delivery (aPR 2.78; 95% CI 2.38 to 3.23. Conclusions In order to improve the rates of breastfeeding within the first hour of life, health care professionals must promote the factors favoring this practice such as prenatal guidance regarding the advantages of breastfeeding, vaginal delivery and full term birth, and stimulate this practice in vulnerable situations such as mothers with cesarean section and preterm birth.

    Full Text Available Abstract Background Sexual function among women undergoing hemodialysis (HD is under-studied and there is no consensus about the effect of sexual dysfunction (SD on their quality of life (QoL. We aimed to determine the prevalence of SD and to compare QoL between women undergoing maintenance HD with and without SD. Methods We included female end-stage renal disease (ESRD patients undergoing HD during June 2011 in the only renal unit in the north of Ceará state, northeastern Brazil. The criteria for inclusion were age between 18 and 55, at least three months on dialysis and being sexually active. Women using antidepressant medication were excluded. We used the Female Sexual Function Index (FSFI, which evaluates six domains of sexual function, including desire, arousal, lubrication, orgasm, satisfaction and pain. The patients were classified as presenting SD if the total FSFI score was less than 26. For QoL evaluation, we used the validated Brazilian version of SF-36. This is a widely used 36-item questionnaire covering eight dimensions of QoL. Demographic data, time on dialysis, underlying etiology of ESRD, and laboratory measures were assessed in unit records. Results Of a total of 58 women, 46 (79.3% presented SD. There were lower scores related to physical functioning (48.2 vs. 71.2; p = 0.007, bodily pain (45 vs. 67.5; p = 0.010, vitality (52.1 vs. 69.1; p = 0.026 and social functioning (57.2 vs. 76.1; p = 0.034 among women with SD compared to women without SD. Physical functioning and role-physical presented positive linear correlation with FSFI scores, respectively, r = 0.322 (p = 0.013 and r = 0.345 (p = 0.007. Conclusion The prevalence of SD among women on HD is very high, reaching nearly 80%. Women on HD with SD had worse QoL, especially physical aspects of QoL, when compared to women without SD. Therefore, approaches aiming to improve QoL among women undergoing HD should be considered.

    Full Text Available For more accurate estimation of the global burden of pregnancy associated disease, clarity is needed on definition and assessment of non-severe maternal morbidity. Our study aimed to define maternal morbidity with clear criteria for identification at primary care level and estimate the distribution of and evaluate associations between physical (infective and non-infective and psychological morbidities in two different low-income countries.Cross sectional study with assessment of morbidity in early pregnancy (34%, late pregnancy (35% and the postnatal period (31% among 3459 women from two rural communities in Pakistan (1727 and Malawi (1732. Trained health care providers at primary care level used semi-structured questionnaires documenting signs and symptoms, clinical examination and laboratory tests which were bundled to reflect infectious, non-infectious and psychological morbidity.One in 10 women in Malawi and 1 in 5 in Pakistan reported a previous pregnancy complication with 1 in 10 overall reporting a previous neonatal death or stillbirth. In the index pregnancy, 50.1% of women in Malawi and 53% in Pakistan were assessed to have at least one morbidity (infective or non-infective. Both infective (Pakistan and non-infective morbidity (Pakistan and Malawi was lower in the postnatal period than during pregnancy. Multiple morbidities were uncommon ( 9. Complications during a previous pregnancy, infective morbidity (p <0.001, intra or postpartum haemorrhage (p <0.02 were associated with psychological morbidity in both settings.Our findings highlight the need to strengthen the availability and quality of antenatal and postnatal care packages. We propose to adapt and improve the framework and criteria used in this study, ensuring a basic set of diagnostic tests is available, to ensure more robust assessment of non-severe maternal morbidity.

Patient cognition was assessed with the cognitive subscale of the Alzheimer's Disease Assessment Scale and Mini-Mental State Examination, function with the Disability Assessment for Dementia, and behavioral and psychological symptoms with the Neuropsychiatric Inventory and the Geriatric Depression Scale. Caregiver burden was assessed with the Zarit Burden Interview and caregiver depression with the Center for Epidemiologic Studies Depression scale. One-way analysis of variance and fully adjusted multiple linear regression were used to assess the relationship between patient dementia symptom and caregiver variables with QOL ratings. In multivariable analyses, caregiver ratings of patient function and depressive symptoms were the only consistent independent predictors of caregiver-rated QOL across the QOL measures. Caregiver ratings of patient function and depression were consistent independent predictors of caregiver-rated QOL, using a spectrum of QOL measures, while measures of patient cognition and caregiver burden and depression were not. These findings support the continued use of caregiver ratings as an important source of information about patient QOL and endorse the inclusion in AD clinical trials of caregiver-rated measures of patient function, depression

    Job stress and burnout are common among healthcare professionals, and nurses in particular. In addition to the heavy workload and lack of recourses, nurses are also confronted with emotionally intense situations associated with illness and suffering, which require empathic abilities. Although empathy is one of the core values in nursing, if not properly balanced it can also have detrimental consequences, such as compassion fatigue. Self-compassion, on the other hand, has been shown to be a protective factor for a wide range of well-being indicators and has been associated with compassion for others. The main goal of this study was to explore how empathy and self-compassion related to professional quality of life (compassion satisfaction, compassion fatigue and burnout). In addition, we wanted to test whether self-compassion may be a protective factor for the impact of empathy on compassion fatigue. Using a cross-sectional design, 280 registered nurses from public hospitals in Portugal's north and center region were surveyed. Professional quality of life (Professional Quality of Life), empathy (Interpersonal Reactivity Index) and self-compassion (Self-compassion Scale) were measured using validated self-report measures. Correlations and regression analyses showed that empathy and self-compassion predicted the three aspects of professional quality of life. Empathic concern was positively associated with compassion satisfaction as well as with compassion fatigue. Mediation models suggested that the negative components of self-compassion explain some of these effects, and self-kindness and common humanity were significant moderators. The same results were found for the association between personal distress and compassion fatigue. High levels of affective empathy may be a risk factor for compassion fatigue, whereas self-compassion might be protective. Teaching self-compassion and self-care skills may be an important feature in interventions that aim to reduce burnout

    In this study, Plantago major seed mucilage (PMSM) was extracted from whole seeds using hot-water extraction (HWE). The dill (D) essential oil components were identified through gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) and its antioxidant properties were examined through the methods of 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant potential (FRAP) and ß-carotene-linoleic acid assay (B-CL). Total phenolic content (TPC) was characterized through the Folin-Ciocalteu method and the antimicrobial effect was evaluated on 10 pathogenic microorganisms. PMSM edible coating incorporated were prepared in four different concentrations of essential oils, including 0, 0.5, 1 and 1.5% (w/w). The control and the coated beef samples were analyzed periodically for microbiological (total viable count, psychrotrophic count, Escherichia coli, Staphylococcus aureus and fungi), chemical (thiobarbituric acid, peroxide value and pH), and sensory characteristics. The IC 50 , FRAP, B-CL and TPC of the dill essential oil were equal to 11.44μg/ml, 9.45mmol/g, 82.86 and 162.65μg/ml GAE, respectively. PMSM extended the microbial shelf life of beef by 3days, whereas the PMSM+0.5%D, PMSM+1%D and PMSM+1.5%D resulted in a significant shelf life extension of the beef by 6, 9 and 9days, respectively, as compared to the control samples.

    Full Text Available Techniques for cesarean delivery, reliable anesthesia, blood products and antibiotics has led to the expansion of indications for cesarean birth. Nowadays, to be comfortable in anesthesia, medicine and materials used in, severe sterilization techniques, advances in surgery and postoperative care were reduced mortality and morbidity. However; caesarean section still include infection, bleeding, need for transfusion, thromboembolic risks of a longer stay in the hospital, later to be healing, but rather risks, such as the withdrawal of the pain continues. Postpartum hemorrhage inside the remaining placentas compared to normal primary complaint is that too much. At the same time ultrasonographic examination of the uterine involution does not occur, the uterus larger than normally. The aim of this case report, and the absence of postoperative bleeding, complete involution of the uterus that have not been diagnosed, and threatened her life was to present a case which is characterized by abdominal abscess.

    With rapid reductions in fertility and mortality, China has to face the dramatic ageing of its population. Although an ageing population is associated with greater life expectancy, and reflects a huge improvement in people's living standards and health care services, it also means that more elderly people suffer from non-communicable diseases (NCDs). The prolonged course of illness and disability associated with chronic diseases may significantly reduce health-related quality of life (HRQoL) among elderly people. The aims of this study were to evaluate HRQoL of elderly people living in Jinzhou, and to identify the predictors of HRQoL. Cross-sectional study with stratified sampling. A cross-sectional survey was conducted among 1015 elderly people (≥60 years) living in the three administrative regions (Linghe, Guta and Taihe) of Jinzhou. A demographic questionnaire and Short Form-36 were employed to collect demographic variables and evaluate HRQoL, respectively. Multiple stepwise linear regression analysis was performed to estimate factors related to HRQoL of the subjects. Lowest HRQoL scores were obtained in the following dimensions: general health (65.44), role-emotional (69.74) and role-physical (70.20). Multiple stepwise regression showed that factors associated with HRQoL of elderly people were medical health checks, age, socio-economic status, NCDs, and various unhealthy lifestyle behaviours such as smoking, excessive drinking and insufficient exercise. This study described overall HRQoL of elderly people in Jinzhou, and found that medical health checks, age, socio-economic status, NCDs, smoking, excessive drinking and insufficient exercise affected HRQoL. These findings will provide a basis for recommendations regarding health management of elderly people, and will also help local government to devise appropriate health intervention strategies for promoting the health status of elderly people in this region.

    The objective of this article was to assess the perception of parents and caregivers regarding the impact of malocclusion on adolescents' oral health -related quality of life (OHRQoL). This cross-sectional study consisted of a sample of 280 parents/caregivers of 11 and 12-year-old adolescents who answered the Parental-Caregiver Perceptions Questionnaire (P-CPQ). Parent-assessed quality of life of adolescents was the dependent variable. The main independent variable was adolescents' malocclusion which was diagnosed by means of the Dental Aesthetic Index (DAI). Based on DAI cut-off points, adolescents were classified into four grades of malocclusion, with different orthodontic treatment recommendations assigned to each grade: no need/slight treatment need, elective treatment, highly desirable treatment and mandatory treatment. Adolescents' age and sex, as well as family monthly income, were considered as confounding variables. Statistical analysis involved descriptive statistics, bivariate analyses, and Poisson regression with robust variance. Of the 280 parents/caregivers initially accepted in this study, 18 refused to answer the P-CPQ. Therefore, 262 individuals participated in this assessment, providing a response rate of 93.5%. The severity of adolescents' malocclusion was significantly associated with a higher negative impact on parents'/caregivers' perception on the oral symptoms (pcontrolling variables. Parents/caregivers reported a negative impact of malocclusion on adolescents' OHRQoL. Increased severity of malocclusion is associated with higher adverse impact on OHRQoL.

    Sports are a major cause of concussions, and little is known about the symptom experience and health-related quality of life (HRQL) in children who remain symptomatic for over 3 months following such head injuries. A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p Children continue to experience many symptoms at least 3 months following sport-related head injuries that significantly impact their HRQL and neurocognitive abilities. © 2015 S.

    Major obstacles exist in the care of patients at the end of life: lack of time, poor or inadequate communication, and lack of knowledge in providing care. Three possible nursing roles in care decision-making were investigated: Information Broker, Supporter, and Advocate. The purpose of this study was to examine obstacles faced by oncology nurses in providing end-of-life (EOL) care and to examine roles of nurses in providing care. A descriptive, cross-sectional, correlational design was applied. The study was conducted at two major University Hospitals of Oncology in Lithuania that have a combined total of 2365 beds. The study sample consisted of 239 oncology registered nurses. Data collection tool included a questionnaire about assessment of obstacles and supportive behaviors, nursing roles, and socio-demographic characteristics. The two items perceived by respondents as the most intense obstacles to providing EOL care were The nurse's opinion on immediate patient care is not welcome, valued or discussed and. Family has no access to psychological help after being informed about the patient's diagnosis. The majority of respondents self-assigned the role of Supporter. Major obstacles in providing care included the nurse's opinion that immediate patient care was not valued, lack of nursing knowledge on how to treat the patient's grieving family, and physicians who avoided conversations with the patient and family members about diagnoses and prospects. In EOL care nurses most frequently acted as Supporters and less frequently as Advocates.

This study explored the association between self-stigma, QoL, demographic data, and the severity of symptoms in patients with depressive disorder. Patients and methods: Patients who met the International Classification of Diseases, 10th revision, research criteria for depressive disorder were enrolled in this cross-sectional study. All outpatients completed the following measurements: the Quality of Life Enjoyment and Satisfaction Questionnaire, the Internalized Stigma of Mental Illness Scale, demographic questionnaire, and the objective and subjective Clinical Global Impression-Severity scales that measure the severity of disorder. A total of 81 depressive disorder patients (with persistent affective disorder – dysthymia, major depressive disorder, or recurrent depressive disorder and 43 healthy controls participated in this study. Results: Compared with the healthy control group, a lower QoL was observed in patients with depressive disorder. The level of self-stigma correlated positively with total symptom severity score and negatively with QoL. Multiple regression analysis revealed that the overall rating of objective symptom severity and score of self-stigma were significantly associated with QoL. Conclusion: This study suggests a lower QoL in patients with depressive disorder in comparison with healthy controls and a negative impact of

    Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: The combined effect of obesity and asthma may lead to significant impairment of quality of life (QOL. The aim here was to evaluate the prevalence of asthma among obese individuals, characterize the severity of impairment of quality of life and measure its relationship with pulmonary function. DESIGN AND SETTING: Observational cross-sectional study in public university hospital. METHODS: Morbidly obese individuals (body mass index > 40 kg/m2 seen in a bariatric surgery outpatient clinic and diagnosed with asthma, were included. Anthropometric data were collected, the Standardized Asthma Quality of Life Questionnaire (AQLQ(S was applied and spirometry was performed. The subjects were divided into two groups based on the median of the score in the questionnaire (worse < 4 and better > 4 and were compared regarding anthropometric data and pulmonary function. RESULTS: Among the 4791 individuals evaluated, 219 were asthmatic; the prevalence of asthma was 4.57%. Of these, 91 individuals were called to start multidisciplinary follow-up during the study period, of whom 82 answered the questionnaire. The median score in the AQLQ(S was 3.96 points and, thus, the individuals were classified as having moderate impairment of their overall QOL. When divided according to better or worse QOL, there was a statistically difference in forced expiratory flow (FEF 25-75%, with higher values in the better QOL group. CONCLUSION: The prevalence of asthma was 4.57% and QOL was impaired among the asthmatic obese individuals. The worst QOL domain related to environmental stimuli and the best QOL domain to limitations of the activities. Worse QOL was correlated with poorer values for FEF 25-75%.

But there is very little information available about QoL in patients with metastatic gastrointestinal cancer. Aims: The aim of this study was to evaluate the quality of life and its associated factors among Iranian patients with metastatic gastrointestinal tract cancer. Materials and Methods: In this cross-sectional study, a total of 250 patients with metastatic gastrointestinal tract cancer were recruited from the one oncology center related to the Mazandaran University of Medical Sciences, Sari, between March 2012 and August 2013. Their QoL was evaluated using the EORTC QLQ-C30 questionnaire (Persian version. Results: In this study, the overall QoL score of patients with gastrointestinal tract cancer was 57.63, which was relatively optimal. There was a statistically significant relationship between symptoms scale and general health status domains of quality of life with age ( P < 0.05. Also, there was a significant association between patients′ gender and their social functioning ( P = 0.017 and also their emotional functioning ( P = 0.015. Conclusions: The findings suggest that in patients with metastatic gastrointestinal cancers, the most affected functions in their QoL were social and emotional functioning which get worse with age. Thus, providing psychological counseling and psychotherapy services to deliver culturally appropriate mental health care and social support for these patients and their families′ which can lead to the improvement of QoL in these patients is strongly recommended.

    The psychological distress of medical students has been widely acknowledged. However, few studies focused on positive well-being among medical students. The purpose of this study was to investigate related demographic factors of life satisfaction among Chinese medical students, to examine the relationship between stress and life satisfaction among this group of people, and to explore the mediating role of resilience in this relationship. This multicenter cross-sectional study was carried out in June 2014. Self-reported questionnaires consisting of Perceived Stress Scale (PSS), Wagnild and Young Resilience Scale (RS-14), Satisfaction with Life Scale (SWLS), as well as demographic section were distributed to students at four medical colleges and universities in Liaoning province, China. A total of 2925 students (effective response rate: 83.6%) became our subjects. Hierarchical linear regression models were used to explore the mediating role of resilience. Among the demographic factors, life satisfaction was significantly different in gender (P = 0.001) and study programs (P life satisfaction (r = -0.35, P life satisfaction (β = -0.34, P life satisfaction among Chinese medical students. Both stress and resilience played a big role in life satisfaction among Chinese medical students. Besides reducing perceived stress, the university authorities should adopt evidence-based intervention strategies to enhance their resilience in order to promote life satisfaction among the students.

    Owing to a scarcity of data or other causes, patient research on the orphan population is lacking in most societies. Consequently, the primary goal of this study was to explore quality of life (QOL) and quality of care (QOC) among orphan patients (OPs) receiving tertiary healthcare services in Saudi Arabia (SA). This study used a cross-sectional, quantitative survey design. Participants included 216 OPs either currently undergoing or who had undergone treatment for common chronic diseases (CDs) (e.g. cardiovascular disease, cancer, stroke and arthritis) during the past 12 months. The survey utilised the brief form from the World Health Organization Quality of Life (WHOQOL-BREF) tool and evaluated healthcare access and effectiveness domains to scrutinise the socio-medical patterns of OPs based on their current medical episodes. The descriptive analysis indicated that OPs' overall QOL reached a moderate level (M = 3.90). Similarly, participants reported relatively high levels of healthcare access and treatment effectiveness (M = 4.14 and M = 4.29, respectively). Stroke patients reported the highest QOL score (M = 3.95), and groups of patients with other CDs reported greater access to healthcare and more effective treatment maintenance compared to the other groups (M = 4.19 and M = 4.43, respectively). Regression analysis was conducted to predict overall QOL based on perceived QOC, and access explained only 6.5 % of the variance. An analysis of variance showed significant differences only between OPs with cardiovascular disease and cancer (P = .001), with the former reporting better access to tertiary healthcare services than the latter. Although some CD patients reported relatively acceptable levels of access to healthcare and receipt of effective treatment, the improvement of OPs' QOL and QOC poses a serious challenge for health policymakers.

    The loss of one's job has been conceptualized as a major stressful life event in an adult's life and has consistently been associated with lower health-related quality of life (HRQoL). The role of cognitive emotion regulation strategies after the experience of stressful events has emerged as an important predictor of adverse psychological and health outcomes. However, the effect of these coping strategies on the HRQoL of unemployed people has not been examined until now. We aimed to study the associations of these cognitive emotion regulation strategies on HRQoL of unemployed people. Using cross-sectional data, 1,125 unemployed adults were assessed using a Cognitive Emotion Regulation Questionnaire for cognitive coping and SF-12 to assess HRQoL. We studied the effect of cognitive emotion regulation strategies on mental and physical health composite separately, adjusting for gender, age, educational level and length of unemployment, using hierarchical regression analyses. Results showed unemployed men tended to express greater use of self-blame, other-blame, and catastrophizing, and lower use of perspective taking strategies when confronted with unemployment. Moreover, self-blame (for mental health composite only), blaming others, rumination, and catastrophizing negatively correlated, while positive reappraisal, putting into perspective, planning, and positive refocusing positively correlated with both mental and physical health composite in unemployed people. Further hierarchical regression analyses indicate that five strategies (a lower reported use of self-blame, rumination, and catastrophizing, as well as higher scores of positive reappraisal and positive refocusing) and three strategies (lower scores of catastrophizing and rumination and high scores in planning) have significant and independent contributions, beyond gender, age, educational level and length of unemployment, to the prediction of mental health and physical health composite, respectively

    Full Text Available Abstract Background Quality of work life (QWL is defined as the extent to which an employee is satisfied with personal and working needs through participating in the workplace while achieving the goals of the organization. QWL has been found to influence the commitment and productivity of employees in health care organizations, as well as in other industries. However, reliable information on the QWL of primary health care (PHC nurses is limited. The purpose of this study was to assess the QWL among PHC nurses in the Jazan region, Saudi Arabia. Methods A descriptive research design, namely a cross-sectional survey, was used in this study. Data were collected using Brooks’ survey of quality of nursing work life and demographic questions. A convenience sample was recruited from 134 PHC centres in Jazan, Saudi Arabia. The Jazan region is located in the southern part of Saudi Arabia. A response rate of 91% (n = 532/585 was achieved (effective response rate = 87%, n = 508. Data analysis consisted of descriptive statistics, t-test and one way-analysis of variance. Total scores and subscores for QWL items and item summary statistics were computed and reported using SPSS version 17 for Windows. Results Findings suggested that the respondents were dissatisfied with their work life. The major influencing factors were unsuitable working hours, lack of facilities for nurses, inability to balance work with family needs, inadequacy of vacations time for nurses and their families, poor staffing, management and supervision practices, lack of professional development opportunities, and an inappropriate working environment in terms of the level of security, patient care supplies and equipment, and recreation facilities (break-area. Other essential factors include the community’s view of nursing and an inadequate salary. More positively, the majority of nurses were satisfied with their co-workers, satisfied to be nurses and had a sense of belonging

  20. Erosion and foreign object damage of thermal barrier coatings

    Thermal barrier coating technology is used in the hot sections of gas turbines to extend component life. To maximise these benefits, the thermal barrier coating has to remain intact throughout the life of the turbine. High velocity ballistic damage can lead to total thermal barrier removal, while erosion may lead to progressive loss of thickness during operation. This paper particularly addresses the erosion resistance and resistance to foreign object damage of thermal barrier coatings. It was found that EB-PVD thermal barriers are significantly more erosion resistant when impacted with alumina or silica, than the equivalent plasma spray coating, both at room temperature and 910 C. Examination of tested hardware, reveals that cracking occurs within the near surface region of the columns for EB-PVD ceramic and that erosion occurs by removal of these small blocks of material. In stark contrast, removal of material for plasma sprayed ceramic occurs through poorly bonded splat boundaries. Large particle impact results in severe damage to the EB-PVD thermal barrier, with cracks penetrating through the ceramic coating to the ceramic/bond coat interface. Material removal, per particle impact, increases with increased particle size. (orig.)

    A spin coating apparatus requires less cleanroom air flow than prior spin coating apparatus to minimize cleanroom contamination. A shaped exhaust duct from the spin coater maintains process quality while requiring reduced cleanroom air flow. The exhaust duct can decrease in cross section as it extends from the wafer, minimizing eddy formation. The exhaust duct can conform to entrainment streamlines to minimize eddy formation and reduce interprocess contamination at minimal cleanroom air flow rates.

    Full Text Available Erectile dysfunction (ED is common among men on opioid replacement therapy (ORT, but most previous studies exploring its prevalence and determinants yielded contrasting findings. Moreover, the impact of ED on patients' quality of life (QoL has been seldom explored.To explore the prevalence and determinants of ED in men on ORT, and the impact on QoL.In a multicentre cross-sectional study, we recruited 797 consecutive male patients on methadone and buprenorphine treatment, collected data on demographic, clinical, and psychopathological factors, and explored their role as predictors of ED and QoL through univariate and multivariate analysis. ED severity was assessed with a self-assessment questionnaire.Nearly half of patients in our sample were sexually inactive or reported some degree of ED. Some demographic, clinical and psychopathological variables significantly differed according to the presence or absence of ED. Multivariate regression analysis indicated that age, employment, smoke, psychoactive drugs, opioid maintenance dosage, and severity of psychopathological factors significantly influenced the risk and severity of ED. QoL was worse in patients with ED and significantly correlated with ED severity. Age, education, employment, opioid maintenance dosage, ED score, and severity of psychopathology significantly influenced QoL in the multivariate analysis.ED complaints can be explored in male opioid users on ORT through a simple and quick self-assessment tool. ED may have important effects on emotional and social well-being, and may affect outcome.

    Health-related quality of life (HRQoL) has been increasingly acknowledged as a valid and appropriate indicator of public health and chronic morbidity. However, limited research was conducted among Chinese civil servants owing to the different lifestyle. The aim of the study was to evaluate the HRQoL among Chinese civil servants and to identify factors might be associated with their HRQoL. A cross-sectional study was conducted to investigate HRQoL of 15,000 civil servants in China using stratified random sampling methods. Independent-Samples t-Test, one-way ANOVA, and multiple stepwise regression were used to analyse the influencing factors and the HRQoL of the civil servants. A univariate analysis showed that there were significant differences among physical component summary (PCS), mental component summary (MCS), and TS between lifestyle factors, such as smoking, drinking alcohol, having breakfast, sleep time, physical exercise, work time, operating computers, and sedentariness (P breakfast, sleep time, physical exercise, operating computers, sedentariness, work time, and drinking (P breakfast, sleep time, physical exercise, work time, operating computers, and sedentariness in China. The performance of the questionnaire in the large-scale survey is satisfactory and provides a large picture of the HRQoL status in Chinese civil servants. Our results indicate that lifestyle factors such as smoking, drinking alcohol, having breakfast, sleep time, physical exercise, work time, operating computers, and sedentariness affect the HRQoL of civil servants in China.

    With a high prevalence of diabetes in India, there is a need to study the impact of this disease on the quality of life (QoL) of the patients. This facility-based cross-sectional study assessed the QoL of patients attending the diabetic clinic using the World Health Organization (WHO) QoL BREF instrument in Tamil Nadu. The QoL was analyzed domain-wise and various socio-demographic factors affecting the QoL were studied. The mean total score of the QoL scale was 58.05 (95% CI, 22.18-93.88). Domain-wise, 63% had good physical, 69% had good psychological, 27% had good social and 85% had good environmental QoL scores. Males, currently married and those with BMI more than 25 had a statistically significantly better QoL compared to their counterparts. Diabetes does impair the QoL of patients but not to a great extent. There is a need to specifically target and improve the QoL of women, widowed and separated, and non-obese diabetics who are at risk of a poor QoL. QoL assessment should be routinely practiced in diabetic clinics.

    The primary objective of this cross-sectional study was to examine the relationship between dog ownership and physical activity in veterinary students. The secondary objective was to gain an understanding of veterinary students' health-related quality of life (HRQOL), and whether dog ownership and/or physical activity were associated with HRQOL measures. Veterinary students were invited to complete surveys between September and November 2015. The primary outcome for multivariate analyses was self-reported physical activity. Bivariate analyses and descriptive statistics were performed to assess student HRQOL. The survey response rate was 33% (152/460). Self-efficacy to exercise (pdog ownership (p=.01, OR 3.38, 95% CI 1.31-8.71) independently predicted meeting physical activity guidelines when controlling for other variables. About two thirds of respondents met physical activity guidelines. Veterinary students had significantly worse self-reported mental health scores when compared to both national and state averages. Neither dog ownership nor meeting physical activity guidelines were significantly associated with measures of HRQOL. The poor mental health status of veterinary students remains a significant issue for the profession to address. Longitudinal studies are needed that examine the relationship between physical activity and mental health outcomes in this population.

    The division of paid and unpaid labor in families continues to be highly gendered with men doing more paid work and women doing more unpaid care work. This is especially true for life stages with young children. Our study investigates the subjective experience of demands in the work and the private domain and the experience of work-life balance across family-life stages as a consequence of this gendered division of labor. We used data from a survey study on work-life issues and health in four large companies in Switzerland (N = 3664). In line with our hypotheses, subjective work and private demands were predicted by an interaction of family-life stages and gender. Specifically, during the primary child-rearing family-life stages, women experience more private demands than men while men experience more work demands, regardless of level of employment. Furthermore, women who work part time experience more work-life balance than women who work full time and more than men who work part or full time during the primary child-rearing family-life stages. Results are discussed in terms of a gendered work-life experience across the life course and the need for part-time work for both genders. Finally, conclusions are drawn concerning our results' implications for public health considerations.

    Full Text Available The objective of the investigation was analysis of the wear of milling cutters made of sintered carbide and of boron nitride. The article presents the life period of the cutting edges and describes industrial conditions of the applicability of tools made of the materials under investigation. Tests have been performed on modern toroidal and ball-end mill cutters. The study has been performed within a production facility in the technology of high speed machining of 55NiCrMoV6 and X153CrMoV12 hardened steel. The analysed cutting speed is a parameter which significantly influences the intensity of heat generated in the cutting zone. Due to the wear characteristics, two areas of applicability of the analysed tools have been distinguished. For vc  ≤ 300 m/min, sintered carbide edges are recommended; for vc  > 500 m/min, boron nitride edges. For 300 ≤ vc  ≤ 500 m/min, a transition area has been observed. It has been proved that the application of sintered carbide edges is not economically justified above certain cutting speed.

    People with eating disorders (ED) often report poor health-related quality of life (HRQoL), which is explicitly correlated to illness' severity and its effects on cognitive performance. We aimed to analyze health-related quality of life (HRQoL) in subgroups of eating disorder (ED) patients by using the brief version of WHOQoL questionnaire (WHOQoL-BREF) before treatment administration. Moreover, in order to compare our findings with other published data, we carried out a comprehensive review of the literature on HRQoL in ED patients. Our review was carried out by means of an accurate data mining of PsychInfo and Medline databases and other available sources. In our cross-sectional study, eighty female ED patients (26 with bulimia nervosa, 33 with anorexia nervosa, 7 with binge eating disorder and 14 with ED not otherwise specified) completed the WHOQoL-BREF. HRQoL scores were compared among ED subgroups and clinical information (presence of previous contacts, length of illness, psychiatric comorbidity) was considered in the analysis. Our review shows that with few exceptions ED patients have a poorer HRQoL than the healthy population of control and sometimes the mental component of HRQoL is the most involved dimension. Moreover, there are no differences in the HRQoL among ED groups, even if AN patients in some studies have a lower HRQoL scores. Furthermore, BED patients have a poorer HRQoL than obese patients who do not have binge episodes. Finally, all treatments were positively correlated with an improvement on general and specific QoL dimensions. In our sample, ED subgroups differed only for Psychological Health HRQoL scores (F = 4.072, df = 3; p = 0.01). No differences were found between inpatients and outpatients, treatment naïve and previously treated patients and patients with or without psychiatric comorbidity. Moreover, HRQoL scores were not correlated to length of illness within each ED subgroup. The analysis of the literature adds some

    Full Text Available Abstract Background Osteoporosis is a systemic skeletal disorder, characterized by reduced bone mass, deterioration of bone structure, increased bone fragility, and increased fracture risk. It is more frequent to find among women than men at a 4:1 ratio. Evidence suggests that to adopt changes on some life habits can prevent or delay development of osteoporosis. Several osteoporosis-risk factors have been confirmed in the US and western Europe, but in El Salvador there are neither reliable epidemiological statistics about this skeletal disorder nor studies addressing osteoporosis-risk factors in women. The aim of this study was to determinate the extent of osteoporosis knowledge, the levels of both daily calcium intake and weight-bearing physical activity, and the influence of several osteoporosis-risk factors on these variables in three age groups of Salvadorean women. Methods In this exploratory cross-sectional study, an osteoporosis knowledge assessment questionnaire incluiding a food frequency and a physical activity record section were used to collect data and it was delivered through a face-to-face interview. A convenience sample (n = 197 comprised of three groups of women aged 25–35 years, 36–49 years, and over 49 years was taken. Among-group comparisons of means were analyzed by two-way ANOVA. To determinate the overall influence of osteoporosis-risk factors, the multivariate analysis was used. Results Study results indicated that better educated women had more knowledge about osteoporosis than women with a low education level, regardless of age, even though this knowledge was rather fair. Older women got more weight-bearing physical activity at home and less at place of employment than reported by the younger women; however, neither group performed sufficient high-intensity WBPA to improve bone mass. Regardless of age, the most women consumed 60% or less than the Dietary Reference Intake of calcium and depend on household income

    The aim of the present study was to identify the relationship of physical activity (PA) and Health-Related Quality of Life (HRQoL) in patients suffering from low back pain (LBP). The present evaluation was conducted as a cross-sectional study based on baseline data of an randomized controlled trial on the effectiveness of an intervention promoting PA. Patients answered a questionnaire on domain specific PA (GPAQ) and HRQoL (EQ-5D-5 L). Furthermore, sociodemographic and indication-specific variables as well as work-related aspects were assessed. Associations of PA and HRQoL were estimated by means of regression analysis: one regression model only included domain specific PA (model 1) and a second regression model additionally included further variables (model 2). 412 patients completed the questionnaire. Model 1 showed opposed effects of workplace and leisure time PA: while workplace PA showed a negative association (β = -0.064; p = 0.04), a positive association of leisure time PA could be proved (β = 0.068; p = 0.01). Model 2 showed that only the variables "current work ability" (β = -0.030; p workplace and leisure time PA in the context of assessing health-enhancing effects of PA in LBP patients. In the context of HRQoL it must be assumed that the relevance of PA might be overestimated. Further research should be performed on predictors of HRQoL and thereby particular attention should be paid on the patients' work-related and indication-specific aspects.

    Despite their public health importance, little is known about associations between modifiable lifestyles, quality of life (QOL), and psychiatric symptoms in men. We investigated relationships between QOL, obesity, mobility and lifestyle in Australian men, including whether associations were mediated by anxiety and depression. A cross-sectional study of 893 men (aged 24-92 yrs) participating in the Geelong Osteoporosis Study: an age-stratified, population-based sample of men randomly recruited from the Barwon Statistical Division (BSD), in south-eastern Australia. Using a validated tool, QOL was measured in the domains of physical health, psychological health, social relationships and the environment. Anxiety and depression were ascertained using the Hospital Anxiety and Depressive Scale. Models were adjusted for age, clinical measures of obesity and mobility, and self-reported lifestyles, with adjustment made for anxiety and depression. Associations were observed between low mobility and lower psychological-related QOL (OR 0.70, 95%CI 0.53-0.93), and for smoking and low mobility with lower environment-related QOL (OR 0.48, 95%CI 0.27-0.84; OR 0.67, 95%CI 0.50-0.90, respectively). Age, anxiety and depression were independently associated with QOL in each domain. Independent of age, anxiety and depression, smoking and low mobility showed particularly strong effects on the likelihood of men reporting a lower satisfaction with their QOL. This information will inform the design of effective and equitable health policies, the allocation of resources toward unmet needs, and the development of strategic health-related plans.

Mental QOL was significantly lower than physical QOL in Chinese unemployed people. Coping had significant effects on both physical component summary (PCS and mental component summary (MCS, while self-efficacy played the mediating role in the association between Coping and QOL. Unemployed Chinese people’s mental QOL was disrupted more seriously than their physical QOL. An increase in coping could improve QOL by promoting better management of issues brought about by unemployment. In addition, self-efficacy has the ability to reduce the impact of unemployment on QOL, through the mediating path of coping on QOL. This study highlights the need of coping skills training and self-efficacy enhancement for better management of unemployment in order to improve QOL and well-being.

    Studies have reported that health-related quality of life (HRQoL) is adversely affected by diabetic foot ulcer (DFU). There is a paucity of data on the effects of foot ulcers on HRQoL of diabetes patients in our population. Because South-Asians, especially Indians, have unique features related to diabetes and its complications, generalizing the data about their effect on HRQoL from any other part of the world is not a pragmatic approach. This study evaluated the impact of foot ulcers on HRQoL of diabetes patients. This cross-sectional study, conducted in Kasturba Hospital, Manipal (coastal South India), included 200 DFU patients in a study group (SG) and 200 diabetes patients in a control group (CG). The RAND-36 questionnaire was employed for evaluating HRQoL scores for the patients in both groups. DFU patients also completed the Diabetic Foot Ulcer Scale-Short Form questionnaire. Independent t-test was used to test the differences in mean scores. Results found that both CG and SG have "poor" HRQoL (mean score Foot Ulcer Scale-Short Form found that HRQoL is very poor for DFU patients on all six domains. The study concludes that DFU patients have very poor HRQoL compared with diabetic patients. Likewise, the diabetic foot is associated with severely impaired HRQoL in both physical and mental health aspects. This study will help to develop a patient education model for DFU patients by looking at the various HRQoL domains that are adversely affected by the presence of foot ulcer.

    Full Text Available Abstract Background Health-related quality of life (HRQoL has been increasingly acknowledged as a valid and appropriate indicator of public health and chronic morbidity. However, limited research was conducted among Chinese civil servants owing to the different lifestyle. The aim of the study was to evaluate the HRQoL among Chinese civil servants and to identify factors might be associated with their HRQoL. Methods A cross-sectional study was conducted to investigate HRQoL of 15,000 civil servants in China using stratified random sampling methods. Independent-Samples t-Test, one-way ANOVA, and multiple stepwise regression were used to analyse the influencing factors and the HRQoL of the civil servants. Results A univariate analysis showed that there were significant differences among physical component summary (PCS, mental component summary (MCS, and TS between lifestyle factors, such as smoking, drinking alcohol, having breakfast, sleep time, physical exercise, work time, operating computers, and sedentariness (P  Conclusion In this study, using Short Form 36 items (SF-36, we assessed the association of HRQoL with lifestyle factors, including smoking, drinking alcohol, having breakfast, sleep time, physical exercise, work time, operating computers, and sedentariness in China. The performance of the questionnaire in the large-scale survey is satisfactory and provides a large picture of the HRQoL status in Chinese civil servants. Our results indicate that lifestyle factors such as smoking, drinking alcohol, having breakfast, sleep time, physical exercise, work time, operating computers, and sedentariness affect the HRQoL of civil servants in China.

    Full Text Available To comprehensively identify the determinants of quality of life (QoL in a population study sample of persons aged 18-50 and 50+.In this observational, cross-sectional study, QoL was measured with the WHOQOL-AGE, a brief instrument designed to measure QoL in older adults. Eight hierarchical regression models were performed to identify determinants of QoL. Variables were entered in the following order: Sociodemographic; Health Habits; Chronic Conditions; Health State description; Vision and Hearing; Social Networks; Built Environment. In the final model, significant variables were retained. The final model was re-run using data from the three countries separately.Complete data were available for 5639 participants, mean age 46.3 (SD 18.4. The final model accounted for 45% of QoL variation and the most relevant contribution was given by sociodemographic data (particularly age, education level and living in Finland: 17.9% explained QoL variation, chronic conditions (particularly depression: 4.6% and a wide and rich social network (4.6%. Other determinants were presence of disabling pain, learning difficulties and visual problems, and living in usable house that is perceived as non-risky. Some variables were specifically associated to QoL in single countries: age in Poland, alcohol consumption in Spain, angina in Finland, depression in Spain, and self-reported sadness both in Finland and Poland, but not in Spain. Other were commonly associated to QoL: smoking status, bodily aches, being emotionally affected by health problems, good social network and home characteristics.Our results highlight the importance of modifiable determinants of QoL, and provide public health indications that could support concrete actions at country level. In particular, smoking cessation, increasing the level of physical activity, improving social network ties and applying universal design approach to houses and environmental infrastructures could potentially increase QoL of

    Measures of health related quality of life (HRQoL) in patients with α1-antitrypsin deficiency (AATD) can help to determine the impact of the disease and provide an important insight into the intervention outcomes. There is few data regarding this issue in the literature. The aim of this study is to assess the relationship between HRQoL and gender, functional parameters and history of hospitalizations in patients with AATD. This is a cross-sectional study of 26 patients with severe AATD recruited in the pulmonology outpatient clinic at a tertiary care medical center. Social-demographic, clinical and functional parameters were recorded and HRQoL was assessed with the Portuguese version of the medical outcome study short form-36 (SF-36) self-administered questionnaire. Older patients, females and patients with at least one hospitalization in the previous year due to respiratory disease had statistical lower scores in some dimensions of the SF-36 questionnaire. Superior FEV1 and higher distance mark in the 6-min walking test distance influenced positively several dimensions of the questionnaire. Higher scores in the mMRC scale influenced negatively the HRQoL. These data suggests that older and female patients with AATD have worse HRQoL. Hospitalizations and functional markers of respiratory disease progression influenced negatively the HRQoL, suggesting that the SF-36 questionnaire could be useful as an outcome for AATD patients with lung involvement.

    In the general population, physical activity is associated with improved health outcomes. However, long-term sports participation may be associated with adverse outcomes, particularly at the elite level. The aims of this study were to assess morbidity and health-related quality of life (HrQoL) amongst former rugby players, compared to an age-standardised general population sample. A cross-sectional study of former elite, male, rugby players (n = 259) was undertaken, and standardised morbidity ratios (SMR) calculated, assessing morbidity prevalence relative to English Longitudinal Study of Aging participants (ELSA, n = 5186). HrQoL, measured using the EQ-5D, was compared to a Health Survey for England (HSE, n = 2981) sample. In SMR analyses of participants aged 50+, diabetes was significantly lower amongst former players, (0.28, 95% CI 0.11-0.66), whereas osteoarthritis (4.00, 95% CI 3.32-4.81), joint replacement (6.02, 95% CI 4.66-7.77), osteoporosis (2.69, 95% CI 1.35-5.38), and anxiety (2.00, 95% CI 1.11-3.61) were significantly higher. More problems in HrQoL were reported amongst former players within the domains of mobility (p < 0.001), self-care (p = 0.041), usual activities (p < 0.001) and pain/discomfort (p < 0.001). Morbidity and HrQoL differ between players and the general population, with higher musculoskeletal morbidity and lower diabetes amongst former players. The magnitude of musculoskeletal morbidity may warrant proactive osteoarthritis management within this population.

    To examine predictive power of psychache and life satisfaction on risks for suicidal ideation and suicide attempt among young people. A cross-sectional study. Data were collected from an online survey in Wuhan, China. 5988 university students from six universities were selected by a stratified cluster sampling method. Suicidal ideation and suicide attempt at some point of the students' lifetime were the outcomes of interest. Students with suicidal ideation or attempted suicide reported a lower level of life satisfaction and high degree of psychache than counterparts without suicidal ideation or attempt. Regression analyses indicated that life satisfaction and psychache were significantly associated with the risk of suicidal ideation and the risk of suicidal attempt. Though psychache showed a relatively stronger predictive power than life satisfaction, the effect of the two factors remained significant when they were individually adjusted for personal demographic characteristics. However, when the two factors were included in the model simultaneously to adjust for each other, psychache could fully explain the association between life satisfaction and suicidal attempt. Life satisfaction remained to contribute unique variance in the statistical prediction of suicidal ideation. Psychache and life satisfaction both have a significant predictive power on risk for suicidal behaviour, and life satisfaction could relieve the predictive power of psychache when suicidal behaviour is just starting. Shneidman's theory that psychache is the pre-eminent psychological cause of suicide is perhaps applicable only to a more serious form of suicidal behaviour.

    Previous studies have highlighted that negative life events and emotional intelligence are significant predictors of mental health. However, whether emotional intelligence mediates the relationship between negative life events and psychological distress among nursing students have not been given adequate attention. To explore the relationship among negative life events, emotional intelligence and psychological distress and to examine the mediating role of emotional intelligence in psychological distress among Chinese nursing students. A cross-sectional survey using convenience sampling. A total of 467 nursing students who were enrolled in a university in mainland of China. A structured questionnaire was administered from September-November in 2013 to participants who consented to participate in the study. Independent variables were personal variables, emotional intelligence and negative life events. Outcome variable was psychological health. The means and standard deviations were computed. Student's t-test and one-way analysis of variance (ANOVA) were performed, to test the differences among the demographic characteristics on the psychological distress scores. Pearson correlation analyses and hierarchical regression analyses were performed. Negative life events were positively associated with psychological distress. Emotional intelligence was negatively associated with psychological distress and negative life events. Emotional intelligence mediated the relationship between negative life events and psychological distress. The findings support the theory of Salovey and his colleagues, and provide evidence for emotional intelligence as a factor that buffers effects of negative life events on psychological distress.

    Improvement of quality of life has been one of goals in health care for people living with bladder cancer. Meanwhile, positive psycho-social variables in oncology field have increasingly received attention. However, the assessment of quality of life of bladder cancer patients and the integrative effects of positive psycho-social variables has limited reporting. The aim of this study was to assess quality of life as well as the integrative effects of social support, hope and resilience on quality of life among Chinese bladder cancer patients. A cross-sectional study was conducted at the First Hospital of China Medical University in Liaoning Province, China. A total of 365 bladder cancer patients eligible for this study completed questionnaires on demographic variables, FACT-BL, Perceived Social Support Scale, Adult Hope Scale, and Resilience Scale-14 during July 2013 to July 2014. The average score of FACT-BL was 87.60 ± 16.27 (Mean ± SD). Hierarchical regression analyses indicated that social support, hope and resilience as a whole accounted for 30.3 % variance of quality of life. Under standardized estimate (β) sequence, social support, hope and resilience significantly and positively associated with quality of life, respectively. Quality of life for bladder cancer patients was at a low level in China, which should receive more attention in Chinese medical institutions. More importantly, efforts to increase social support, hope and resilience might be useful to support the quality of life among Chinese bladder cancer patients.

    Full Text Available Well-being is often mentioned as an important motive for organic food consumption. Little is known about the relationship between organic food consumption and life satisfaction (a component of well-being. The aim of this study was to investigate the cross-sectional relationship between organic food consumption and life satisfaction.A total of 17,446 volunteers aged 45 or above, from the NutriNet-Santé cohort filled in an organic food semi-quantitative frequency questionnaire and completed the French validated satisfaction with life scale (range score 5–35. Adjusted means (95% confidence intervals of the satisfaction with life score across quintiles of contribution of organic food to the diet (total and by food group were estimated using ANCOVA models.In multivariable model, life satisfaction among lowest and highest consumers of organic food reached 24.98 (95%CI: 24.78–25.17 and 25.52 (95%CI: 25.33–25.71 respectively (P trend<0.0001. Life satisfaction was slightly and positively associated with higher contribution of organic food to the diet (overall and in most food groups.Our findings suggest that high organic food consumption may play a role in life satisfaction of participants over 45years old through hedonist or eudemonic approaches.

    Modifiable lifestyle factors, such as diet quality, could reduce inflammation and improve quality of life (QOL) in breast cancer survivors, but data are inconclusive. To determine whether diet quality, as measured by Healthy Eating Index-2010 (HEI-2010) score, is associated with inflammation, health status, or functional outcomes affecting QOL in survivors of early-stage breast cancer. This is a cross-sectional, secondary analysis of baseline data collected from breast cancer survivors after completion of primary therapy and before random assignment to a pilot nutritional intervention aimed at reducing side effects of aromatase inhibitor treatment. Participants were 44 postmenopausal women with stage I to III endocrine receptor-positive breast cancer receiving outpatient care at a midwestern cancer center between November 2011 and October 2013. Primary outcomes were serum proinflammatory cytokines (interleukin-6 [IL-6], IL-17, and tumor necrosis factor-α receptor 2 [TNFR-2]). Secondary outcomes included QOL measured by the Stanford Health and Disability Questionnaire and the Functional Assessment of Cancer Therapy-Breast with Endocrine Subscale. Pearson correlation coefficients (r) and linear regression models were used to evaluate the relationship of dietary variables with inflammatory cytokines and QOL measures. A higher overall HEI-2010 score (healthier diet) was associated with lower IL-6 (r=-0.46; P=0.002) and TNFR-2 (r=-0.41; P=0.006); however, associations were attenuated by body mass index (BMI) (IL=6 [r=-0.26; P=0.10]; TNFR-2 [r=-0.30; P=0.06]). In women with prior chemotherapy, a higher HEI-2010 score was strongly associated with lower IL-6 (r=-0.67; P=0.009) and TNFR-2 (r=-0.59; P=0.03) after BMI adjustment. There were no significant correlations between HEI-2010 score and QOL measures after adjustment for BMI. These data suggest the need for more rigorous investigation into the relationship of diet quality, BMI, and inflammation in breast cancer

    Full Text Available Studies in the general population suggest that determinants of QoL are often sex-dependent. Sex-dependent analyses of QoL in transgender populations have not been performed so far.To identify sex-specific and potentially modifiable determinants of QoL in transgender patients.In this cross-sectional multicentre study including 82 transwomen (TW and 72 transmen (TM at different treatment stages, we investigated potential determinants for QoL focusing on the impact of mood (BDI, STAI-X, sleep quality (PSQI, chronic pain (GPQ, body image (FBeK and social support (SSS.Health-related quality of life measured with the Short Form (36 Health Survey (SF-36.The age-adjusted SF-36 total score and its subscales did not significantly differ between TM and TW. Using a multivariate regression analysis approach, we identified common but also sex-dependent determinants for QoL (Adjusted R2 = 0.228; 0.650 respectively. Accounting for general characteristics such as age, BMI and treatment status, sleep quality according to the PSQI was an independent and strong determinant of QoL in both sexes (β = -0.451, p = 0.003 TM; β = -0.320; p = 0.0029 TW. Chronic pain was a significant independent predictor of QoL in TM (β = -0.298; p = 0.042 but not in TW. In contrast, anxiety (β = -0.451; p< 0.001 being unemployed (β = -0.206; p = 0.020 and insecurity about the own appearance (FBeK (β = -0.261; p = 0.01 were independent predictors of QoL in TW. The rate of those reporting high sleep disturbances (PSQI ≥5 was high with 79.2% in TW and 81.2% in TM. Accordingly, age-adjusted QoL was also significantly lower in those reporting poor sleep in both sexes.Sleep strongly affected QoL in both genders, while other factors, like pain and body image, seem to be gender specific in transgender individuals.

    To compare the impact of chronic pain physiopathology on health-related quality of life (HR-QoL), considering the influence of pain features and psychosocial adjustment (intensity, interference, psychological comorbidities, and sleep quality). A cross-sectional study involving 1,025 noncancer patients with predominantly neuropathic, nociceptive, or mixed chronic pain conditions was conducted in 88 pain clinics within Spain. The EuroQol-5 Dimensions instrument (EQ-5D) was used to measure HR-QoL. The Brief Pain Inventory (BPI), Hospital Anxiety and Depression Scale (HADS), and sleep scale developed for the MOS study (MOS-SQ) were used to measure pain features and psychosocial adjustment. Multivariate analyses were used to model HR-QoL measures. All patients reported very low HR-QoL. The mean EQ-5D index scores were 0.33, 0.36, and 0.37 in the mixed, neuropathic, and nociceptive pain groups, respectively. The differences did not reach statistical significance (P = 0.057). Patients with nociceptive pain had less pain (least pain intensity score: 4.7 vs. 5.2 in the other groups; P = 0.006), less interference with daily activities (BPI average interference score: 6.3 vs. 6.6 and 6.7 in the neuropathic and mixed pain groups, respectively; P = 0.013), less anxiety (HADS score: 8.5 vs. 9.6 and 9.7 in the same respective groups; P = 0.001), and fewer sleep problems (MOS-SQ sleep problems index: 46.8 vs. 52.2 and 50.2 in the same respective groups; P = 0.005). In the adjusted analyses, HR-QoL measures were explained by pain intensity, anxiety, and sleep quality, but not by physiopathological pain type. Pain features, particularly intensity, have a greater impact than pain physiopathology on HR-QoL. Distinct physiopathological mechanisms give rise to different pain features that, in turn, may mediate the HR-QoL of patients with chronic pain. This could be used to improve pain management strategies. © 2016 World Institute of Pain.

    Full Text Available To assess the quality of life (QOL of Saudi Arabian patients undergoing hemo-dialysis (HD and to determine the impact of gender, age, education and comorbidities on the QOL of these patients, we conducted a cross-sectional study and used the short form-36 (SF-36 questionnaire, a generic instrument for measuring QOL. This questionnaire is composed of eight scales that summarize the physical component scale (PCS and mental component scale (MCS of health status. We calculated the PCS and MCS scores for each patient. We studied 205 HD patients (123 men; ages 18-75 years from the King Fahd General Hospital, Jeddah, Saudi Arabia. The mean SF-36 score was 59.4 ± 21.7 in men and 41.9 ± 20.9 in women (P <0.0001. Patients older than 60 years had the worst score (41.5 ± 21.2, followed by patients aged 40-59 years (53.6 ± 22.8; patients aged 18-39 years had the best SF-36 score (57.5 ± 22.5; P <0.0001. Education had a positive impact on QOL (P <0.0001, whereas comorbid conditions had a nega-tive impact. Peripheral vascular disease was associated with the worst outcome (SF-36 score, 40.4 ± 23.0; P <0.0001, followed by dyslipidemia (42.9 ± 22.4; P = 0.001 and diabetes mellitus (45.0 ± 22.0; P = 0.012. Among the comorbid conditions, hypertension was associated with the best SF-36 score (50.6 ± 22.7; P = 0.034. We conclude that old age, female gender, poor education and comorbid conditions have a negative impact on the QOL of HD patients in Saudi Arabia. These findings indicate a general need for social support for female patients on HD and early diagnosis and management of comorbid conditions.

    Metabolic syndrome (MetS) significantly correlates with exercise. MetS also has an independent and inverse correlation to quality of life (QoL). However, few studies have examined the association between exercise and QoL in people with MetS. The aim of this study was to ascertain the relationship between exercise and QoL in a MetS population. This was a cross-sectional study using public data from the Sixth Korean National Health and Nutrition Examination Survey in 2014 (n = 7550). MetS was defined on the basis of the revised National Cholesterol Education Program criteria. Demographic factors, three types of exercise (resistance, flexibility, walking), five subsets of EuroQoL (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), and QoL scores (EQ-VAS), were investigated. Independent associations of each exercise on five subsets of QoL were determined using odds ratios (OR) adjusted for four demographic factors (age group, sex, weight change, and area of residence) using multivariate logistic regression analysis. Prevalence of MetS was 26.4% and the ratio of subjects performing resistance, flexibility, or walking exercise was 17.7%, 45.8%, and 71.5% among this population, respectively. EQ-VAS of exercisers was significantly higher than that of non-exercisers in resistance, flexibility, and walking exercise. Although resistance and flexibility exercise did not correlate with any subsets of QoL, mobility and self-care were significantly associated with walking exercise (OR = 0.635, 95% CI = 0.439-0.919 and OR = 0.577, 95% CI = 0.348-0.958, respectively). All exercisers showed higher QoL scores than non-exercisers. Among QoL subsets, mobility and self-care were independently associated with walking exercise in the MetS population. Regular walking exercise was important to higher QoL in those with MetS. This is the first clinical report to indicate that QoL could be independently influenced by walking exercise.

    SiC/SiC Ceramic Matrix Composites (CMCs) are increasingly being considered as structural materials for advanced power generation equipment because of their light weight, higher temperature capability, and oxidation resistance. Limitations of SiC/SiC CMCs include surface recession and component cracking and associated chemical changes in the CMC. The solutions pursued to improve the life of SiC/SiC CMCs include the incorporation of coating systems that provide surface protection, which has become known as an Environmental Barrier Coating (EBC). The development of EBCs for the protection of gas turbine hot section CMC components was a continuation of coating development work for corrosion protection of silicon-based monolithics. Work on EBC development for SiC/SiC CMCs has been ongoing at several national laboratories and the original gas turbine equipment manufacturers. The work includes extensive laboratory, rig and engine testing, including testing of EBC coated SiC/SiC CMCs in actual field applications. Another EBC degradation issue which is especially critical for CMC components used in aircraft engines is the degradation from glassy deposits of calcium-magnesium-aluminosilicate (CMAS) with other minor oxides. This paper addresses the need for and properties of external coatings on SiC/SiC CMCs to extend their useful life in service and the retention of their properties.

    The importance of transformational leadership for nurses' well-being is increasingly acknowledged. However, there is a paucity of research examining the mechanisms that may explain the relationships between transformational leadership and nurses' quality of work life. First, to examine two possible psychological mechanisms that link transformational leadership behaviors to nurses' quality of work life. Second, to study the relationship between nurses' quality of work life and their work engagement. Cross-sectional study design. The study took place in 47 different hematology, oncology, and hematology/oncology units in France. Participants were nurses and auxiliary nurses. 343 nurses completed the questionnaire. Surveys were sent to all nurses working in the units. 95% were female, the average age was 36.30 years. Nurses were asked to rate their supervisor's transformational leadership style and their perceptions of distributive and interactional justice in the unit. They were also asked to evaluate their own level of quality of work life and their work engagement. Distributive justice and interactional justice were found to fully mediate the relationship between transformational leadership and nurses' quality of work life. In addition, nurses' quality of work life positively related to their work engagement. Transformational leaders may help ensure nurses' quality of work life which in turn increases their work engagement. These leadership practices are thus beneficial for both employees and organization. Copyright © 2012 Elsevier Ltd. All rights reserved.

    A high quality of work life (QWL) is a crucial issue for health care facilities to have qualified, dedicated, and inspired employees. Among different specialties in health care settings, nurses have a major share among other health care providers. So, they should experience a better QWL to deliver high-quality holistic care to those who need help. To assess the level of quality of work life and its predictors among nurses working in Hawassa town public health facilities, South Ethiopia. A facility based cross-sectional study was conducted on 253 nurses of two hospitals and nine health centers. The total sample size was allocated to each facility based on the number of nurses in each facility. Data were collected using a structured questionnaire. The interitem consistency of the scale used to measure QWL had Cronbach's alpha value of 0.86. A multinomial logistic regression model was fitted to identify significant predictors of quality of work life using SPSS version 20. The study showed that 67.2% of the nurses were dissatisfied with the quality of their work life. We found that educational status, monthly income, working unit, and work environment were strong predictors of quality of work life among nurses ( p quality of their work life. The findings in this study and studies reported from elsewhere pinpoint that perception of nurses about the quality of their work life can be modified if health care managers are considerate of the key issues surrounding QWL.

    Nurses\\' knowledge regarding advance directives may affect their administration and completion in end-of-life care. Confidence among nurses is a barrier to the provision of quality end-of-life care. This study investigated nurses\\' knowledge of advance directives and perceived confidence in end-of-life care, in Hong Kong, Ireland, Israel, Italy and the USA using a cross-sectional descriptive design (n = 1089). In all countries, older nurses and those who had more professional experience felt more confident managing patients\\' symptoms at end-of-life and more comfortable stopping preventive medications at end-of-life. Nurses in the USA reported that they have more knowledge and experience of advance directives compared with other countries. In addition, they reported the highest levels of confidence and comfort in dealing with end-of-life care. Although legislation for advance directives does not yet exist in Ireland, nurses reported high levels of confidence in end-of-life care.

    Full Text Available It has been shown that frailty is associated with low levels of wellbeing and life satisfaction. Further exploration is needed, however, to better understand which components constitute life satisfaction for frail older people and how satisfaction is related to other life circumstances. The aim of this study was to examine relationships between frail older people’s life satisfaction and their socioeconomic conditions, social networks, and health-related conditions. A cross-sectional study was conducted (n=179. A logistic regression analysis was performed, including life satisfaction as the dependent variable and 12 items as independent variables. Four of the independent variables made statistically significant contributions: financial situation (OR 3.53, social contacts (OR 2.44, risk of depression (OR 2.26, and selfrated health (OR 2.79. This study demonstrates that financial situation, self-rated health conditions and social networks are important components for frail older people’s life satisfaction. Health and social care professionals and policy makers should consider this knowledge in the care and service for frail older people; and actions that benefit life satisfaction − such as social support − should be promoted.

    Previous studies on quality of life of patients with stoma in Poland included small groups of respondents and were based either on the non-validated questionnaires created ad hoc, or on the disease-specific oncologic questionnaires. To assess quality of life of Polish patients with a stoma using validated generic questionnaire. Adult patients with colostomy, ileostomy or urostomy performed in Poland between July 2009 and March 2010 were included. Patients completed satisfaction survey at the discharge from the hospital, and The World Health Organization Quality of Life-BREF (WHOQOL-BREF) generic questionnaire at 3 months after surgery. The study involved 737 patients (71%, 18%, 11% with colostomy, ileostomy and urostomy, respectively). The studied population was highly diversified in terms of: dependence on medical treatment, pain and discomfort, satisfaction with health and acceptance of physical appearance. 59% of patients with a stoma defined their quality of life as very good or good (mean 3.56 points; range: 1 to 5; SD 0.74). The subjects were characterized by low quality of life assessment in the physical health and psychological domains (52.9 and 60.1 pts.) and by high evaluation in the environment and social relationships domains (69.7 and 70.1 pts.). Respondents highly assessed: the level of social support, home environment, physical environment, personal relationships. Low assessment was related to: sexual activity, ability to work, dependence on medical treatment, financial resources, satisfaction with health. Quality of life in patients with a stoma, assessed at three months after the surgery, is higher when compared to typical patients hospitalized in the internal medicine ward. Identified quality of life limitations relate in particular to sexual life.

    Thermal barrier coatings will be more aggressively designed to protect gas turbine engine hot-section components in order to meet future engine higher fuel efficiency and lower emission goals. In this presentation, thermal barrier coating development considerations and requirements will be discussed. An experimental approach is established to monitor in real time the thermal conductivity of the coating systems subjected to high-heat-flux, steady-state and cyclic temperature gradients. Advanced low conductivity thermal barrier coatings have also been developed using a multi-component defect clustering approach, and shown to have improved thermal stability. The durability and erosion resistance of low conductivity thermal barrier coatings have been improved utilizing advanced coating architecture design, composition optimization, in conjunction with more sophisticated modeling and design tools.

    Studies from high-income settings show that both food insecurity and common mental disorders (CMDs) are associated with lower quality of life among people living with HIV (PLHIV). However, there is limited research among PLHIV in sub-Saharan Africa. In this study we tested the hypothesis that food insecurity and CMDs would be associated with poorer quality of life of PLHIV in Ethiopia. A cross-sectional study was carried out with 348 PLHIV who were initiating antiretroviral therapy recruited from two primary care centers and a tertiary Hospital in southwest Ethiopia. Food insecurity, CMD, and quality of life were measured using instruments adapted and validated in Ethiopia (Household Food Insecurity Access Scale, Kessler-6, and WHOQOL-HIV-BREF-ETH, respectively). Multiple linear regression analysis was used to identify factors associated with quality of life after adjusting for confounders. The prevalence of severe household food insecurity among PLHIV was 38.7 %. After adjusting for confounders, severe food insecurity (β = -3.24, 95 % CI: -6.19; -0.29) and higher levels of CMD symptoms (β = -1.72 for each 1 point increase, 95 % CI: -1.94; -1.49) were associated with lower quality of life. Other factors associated with lower quality of life were advanced HIV disease (β = -3.80, 95 % CI: -6.18; -1.42), and being underweight (BMI = 17.0 - 18.5 kg/m(2)) (β = -3.45, 95 % CI: -6.18; -0.71). Owning more household assets was associated with higher quality of life (β = 0.99 for owning one more asset, 95 % CI: 0.09; 1.89). Poor mental health and food insecurity are associated with lower quality of life in PLHIV. There is a need for longitudinal studies to elucidate the pathways linking CMD, food insecurity and quality of life.

    Restorative anterior resection is considered the optimal procedure for most patients with rectal cancer and is frequently preceded by radiotherapy. Both surgery and preoperative radiotherapy impair bowel function, which adversely affects quality of life. This study aimed to report symptoms associated with and key predictors for bowel-related quality-of-life impairment. The study included a cross-sectional cohort. This was a multicenter study from 12 United Kingdom centers. A total of 578 patients with rectal cancer underwent curative restorative anterior resection between 2001 and 2012 (median, 5.25 years postsurgery). Patients completed outcome measures that assessed bowel dysfunction (low anterior resection syndrome score), incontinence (Wexner score), and quality of life (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30), plus an anchor question: "Overall how does bowel function affect your quality of life?" The response rate was 80% (462/578). Overall, 85% (391/462) of patients reported bowel-related quality-of-life impairment, with 40% (187/462) reporting major impairment. A large difference in global quality of life (22 points; p cancer treated with and without preoperative radiotherapy compared with 47% and 33% of middle/upper rectal cancers with and without preoperative radiotherapy. Advances in radiotherapy delivery and improvements in posttreatment symptom control, although currently of limited efficacy, imply that the content of this consent aid should be re-evaluated in 5 to 10 years. Before a restorative anterior resection, patients with rectal cancer should be informed that bowel-related quality-of-life impairment is common. The key risk factors are neoadjuvant therapy and a low tumor height. This study presents quality-of-life and functional outcome data, along with a consent aid, that will enhance this preoperative patient discussion.

    Sleep disturbances are common in women, especially during pregnancy. Previous studies have confirmed the importance of sleep disturbances as a risk factor of adverse pregnancy outcomes and the need for screening and treatment of inadequate sleep. These reports, however, did not examine health-related quality of life which may be affected by sleep long before adverse clinical consequences are detectable in women during pregnancy. To examine the cross-sectional and longitudinal association between sleep and health-related quality of life in pregnant women. A prospective observational study. A university-affiliated hospital in Taiwan and participants' homes. A total of 164 pregnant women completed questionnaires and wore a wrist actigraphy monitor for 7 days each trimester. Objective sleep was measured by actigraphy, subjective sleep was measured by the Pittsburgh Sleep Quality Index, and health-related quality of life was measured using the SF-12v2 questionnaire across three trimesters. Multiple linear regression analyses were performed to evaluate the cross-sectional and longitudinal associations between sleep and health-related quality of life. Sixty-four (39.0%) women consistently had an average sleep efficiencySleep Quality Index global score>5 in all three trimesters. Cross-sectionally, more actigraphic daytime sleep (p=0.04) and better subjective sleep quality (pquality of life in first-trimester pregnant women. Better actigraphic sleep efficiency (p=0.04) and better subjective sleep quality (pquality of life in second-trimester pregnant women.

    Full Text Available Death is beyond one's personal control, generates great concern and anxiety, among human beings. Studies exploring the association between religious attitudes and death attitudes in adolescents and young adults in postmodern society are scarce. This study examines the relationship between five dimensions of attitude toward death (fear of death, death avoidance, neutral acceptance, approach acceptance, and escape acceptance, death anxiety, life satisfaction and meaning, religiosity and selected personal factors among health care staff and students in three teaching hospitals. A total of 230 adolescents and adults both sexes who were willing participated. Diener et al Satisfaction with Life, Steger et al Meaning of Life Questionnaire; Templer's Death Anxiety Scale, Wong's Death Attitude Profile-R and a religious attitude scale were administered. Findings showed students' search for meaning was higher than faculty. An unusual finding of higher Approach acceptance death attitude in students emerged. Correlation analysis revealed that presence of meaning was related to greater life satisfaction in both groups. It was further related to higher religiosity in both groups and higher neutral acceptance of death and lesser death anxiety in students alone. In both groups search for meaning was positively associated with death anxiety. Faculty's search for meaning was positively associated with negative death attitudes and surprisingly one positive death attitude. Death anxiety was more with faculty's advancing age, and was also more when both groups held negative death attitudes. Religiosity was positively associated with death anxiety in students. Further, religiosity was not only positively associated with positive death attitudes of approach acceptance (both groups and neutral acceptance (faculty but also with negative attitude of death avoidance (faculty. Death anxiety was more despite both groups embracing approach acceptance death attitude indicating

    Full Text Available To analyse how patients with chronic diseases would interpret their illness, and how these interpretations were related to spirituality/religiosity, life satisfaction, and escape from illness, we performed a cross-sectional survey among patients with chronic diseases from Poland (n = 275 using standardized questionnaires. Illness was interpreted mostly as an Adverse Interruption of life (61%, Threat/Enemy (50%, Challenge (42%, and rarely as a Punishment (8%. Regression analyses revealed that escape from illness was the best predictor of negative disease perceptions and also strategy associated disease perceptions, and a negative predictor of illness as something of Value, while Value was predicted best by specific spiritual issues. Patients’ religious Trust and partner status were among the significant contributors to their life satisfaction. Data show that specific dimensions of spirituality are important predictors for patients’ interpretation of illness. Particularly the fatalistic negative perceptions could be indicators that patients may require further psychological assistance to cope with their burden.

    The quality of life is an important indicator of quality of care in chronic diseases such as diabetes and TB. The present research is conducted with an aim to assess the Quality of Life of Diabetic Patients with Smear Positive PTB. This cross-sectional study was conducted on 62 diabetic patients with smear positive PTB from January to May 2016 in a diabetes clinic in Zahedan city (southeast of Iran). A simple random sampling method was used in this study. Instrument for data collection was quality of life (SF-36) questioner. Total quality of life score was 48 that showed an average level of quality of life. Sixty-five patients with diabetes and affected by smear positive pulmonary tuberculosis (PTB) with the average age of 51.30±10.84 years participated in this research. Four patients (0.06%) suffered from type 1 diabetes and 58 (94%) from type 2 diabetes, and all of them were smear positive PTB patients. Study of their quality of life revealed that, in general, the average scores for quality of life in the two main subgroups of physical health and mental health were lower than the average and, among the eight studied dimensions, the highest scores were those for physical activity (60±14.23) and the lowest (31.42±12.14) for general health in the subgroup of physical health. Results indicated that the patients had a low quality of life although they received the care and treatments that are effective in patients with diabetes and suffering from smear-positive PTB.

    Although health literacy and quality of life are important concepts in health care, the link between them is unclear, especially for a population of frequent users of health care services with chronic diseases. Low health literacy is a common problem that has been linked to several negative health outcomes. Quality of life is an important health outcome in patient-centered care. Frequent users of health care services are a vulnerable population that deserves attention due to high costs and negative outcomes such as lower quality of life and higher mortality. The objective of this study was to examine the relationship between health literacy and the physical and mental components of quality of life among frequent users of health care services with chronic diseases. This study presents the cross-sectional analysis of data collected through the V1SAGES project, a randomized controlled trial on the effectiveness of a case management intervention in primary care in Quebec, Canada. Participants (n = 247) were frequent users of health care services presenting at least one chronic condition. Health literacy was measured by the Newest Vital Sign (NVS), and the physical and mental components of quality of life were evaluated by the Short Form Health Survey Version 2 (SF-12v2). The association between health literacy (independent variable) and the physical and mental components of quality of life was examined using biserial correlation. No association was found between health literacy and quality of life (physical component: r = 0.108, ρ = 0.11; mental component: r = 0.147, ρ = 0.15). This study suggests that there is no relationship between health literacy and the physical and mental components of quality of life among frequent users of health care services. NCT01719991 .

    Full Text Available Abstract Background The objective of this study was to examine the association between infection early in life and mental disorders among youth in the community. Methods Data were drawn from the MECA (Methods in Epidemiology of Child and Adolescent psychopathology, a community-based study of 1,285 youth in the United States conducted in 1992. Multiple logistic regression analyses were used to investigate the association between parent/caregiver-reported infection early in life and DSM/DISC diagnoses of mental disorders at ages 9-17. Results Infection early in life was associated with a significantly increased odds of major depression (OR = 3.9, social phobia (OR = 5.8, overanxious disorder (OR = 6.1, panic disorder (OR = 12.1, and oppositional defiant disorder (OR = 3.7. Conclusions These findings are consistent with and extend previous results by providing new evidence suggesting a link between infection early in life and increased risk of depression and anxiety disorders among youth. These results should be considered preliminary. Replication of these findings with longitudinal epidemiologic data is needed. Possible mechanisms are discussed.

    Life drawing sessions, where individuals produce drawings of the human figure from observations of a live model, may contain embodying elements that promote healthier body image. Two pilot studies were conducted to test this hypothesis. In Study 1, 138 individuals recruited from life drawing sessions in London, UK, estimated how many sessions they had attended in their lifetime and completed measures of negative and positive body image. In women, greater attendance was significantly associated with higher body appreciation and lower drive for thinness and social physique anxiety. In men, greater attendance was significantly associated with higher body appreciation, but not drive for muscularity or social physique anxiety. In Study 2, 37 women took part in a life drawing session for the first time. Compared to pre-session scores, participants had significantly more positive state body image and appearance satisfaction after the session. The findings of these studies suggest that life drawing may promote healthier body image, particularly among women, but further research is needed. Copyright © 2015 Elsevier Ireland Ltd.

    Population aging leads to increased burden of chronic diseases and demand in public health. This study aimed to assess whether the score of Primary Health Care (PHC) is associated with a) the model of care - Family Health Strategy (FHS) vs. traditional care model (the Basic Health Units; BHU); b) morbid conditions such as - hypertension, diabetes mellitus, mental disorders, chronic pain, obesity and central obesity; c) quality of life in elderly individuals who received care in those units. A survey was conducted among the elderly between August 2010 and August 2011, in Ilheus, Bahia. We interviewed elderly patients - 60 years or older - who consulted at BHU or FHS units in that day or participated in a group activity, and those who were visited at home by the staff of PHC, selected through a random sample. Demographic and socioeconomic characteristics, services' attainment of primary care attributes, health problems and quality of life were investigated. The Short Form Health Survey (SF-12) was used to assess quality of life and PCATool to generate PHC scores. In addition, weight, height and waist circumference were measured. Trained research assistants, under supervision performed the data collection. A total of 511 elderly individuals were identified, two declined to participate, resulting in 509 individuals interviewed. The health care provided by the FHS has higher attainment of PHC attributes, in comparison to the BHU, resulting in lower prevalence of score below six. Except for hypertension and cardiovascular disease, other chronic problems were not independently associated with low scores in PHC. It was observed an independent and positive association between PHC score and the mental component of quality of life and an inverse association with the physical component. This study showed higher PHC attributes attainment in units with FHS, regardless of the health problem. The degree of orientation to PHC increased the mental component score of quality of life.

    Quality of life must be one of the main purposes for the treatment of drug users, requiring a better understanding of the association between the quality of life and the severity of dependency. This study aimed to investigate the correlation between severity of substance use in various areas of human functioning and quality of life of illicit drug users in a psychosocial care center for alcohol and drugs. This cross-sectional study included 60 participants - illicit drug users - treated at a psychosocial care center for alcohol and drugs. Participants were evaluated with the short version of World Health Organization Quality of Life (WHOQOL-Bref) instrument to measure the quality of life, the 6th version of Addiction Severity Index (ASI-6) to assess the severity of dependence in several areas and the Mini International Neuropsychiatric Interview (MINI) to identify the presence of psychiatric disorders. Pearson and Spearman correlation tests and linear regression were applied to verify the association between the severity of dependence and the quality of life, and Student's t-test to compare the mean quality of life between individuals with and without psychiatric comorbidities. Negative correlation was found between the severity of dependence on the drugs dimensions: alcohol, psychiatric, medical, legal, family/social support and family/social problems of ASI-6, and the quality of life domains measured by the WHOQOL-Bref. The evidence was strongest in the psychiatric and medical dimensions. There was a significant difference in the quality of life mean among participants presenting or not presenting psychiatric comorbidities, for the psychological domain in anxiety disorders, and for the physical and psychological domains in mood disorders. The quality of life decreased as the severity of dependence increased, with different results in the various areas of the participant's life. This result emphasizes the need for training the professional team which works in the

    Although survival rates in childhood cancer have distinctly improved, pediatric cancer patients often experience various disease- and treatment-related side effects with long-term consequences. Despite current studies investigating inactivity and limitations in physical functioning and quality of life in pediatric cancer patients, only little information regarding specific deficits in physical functioning and quality of life has been available until now. No study has yet analyzed these parameters from a global perspective and then identified specific deficits in a mixed childhood cancer population. Within this cross-sectional pilot study, motor performance and quality of life of 26 pediatric cancer patients were assessed after inpatient medical treatment, using standardized motor test batteries (MOT 4-6; DMT 6-18) and a quality of life questionnaire (KINDL®). Reference data have been mainly provided by the German "Children and Young People Health Survey" (KiGGS). Patients achieved lower motor performance scores (p = .000) (more than 27% below the average of healthy peers). Specific deficits were identified in motor speed and motor control (4-6 years), as well as in endurance, strength and coordination under time pressure (6-17 years). In terms of quality of life, no significant differences were examined compared to healthy children of the same age. The results of this study confirm that children with oncological diseases frequently have specific motor problems. Future research in pediatric oncology must investigate the impact of targeted, individualized exercise interventions addressing these specific deficits.

    Full Text Available Rhinitis is a common medical condition and can seriously impact patients’ quality of life. The objective of this study was to investigate the association between disease-specific quality of life and use of complementary and alternative medicine (CAM modalities among Taiwanese rhinitis patients. A cross-sectional survey was undertaken at the outpatient department of otolaryngology in a medical center in Taiwan. Sociodemographic information, disease-specific quality of life (Chinese version of the 31-item Rhinosinusitis Outcome Measure, CRSOM-31, and previous use of CAM modalities for treatment of rhinitis of the patients were ascertained. Factor analysis was performed to reduce the number of CAM modalities. The resulting factors were analyzed for their association with CRSOM-31 score using linear regression analyses. Results from the multiple linear regression analyses indicated that Factor 1 (traditional Chinese medicine, Factor 2 (mind-body modalities, Factor 3 (manipulative-based modalities, female sex, and smoking were significantly associated with a worse disease-specific quality of life. In conclusion, various CAM modalities, female sex, and smoking were independent predictors of a worse disease-specific quality of life in Taiwanese patients with rhinitis.

    Three experimental research designs investigating candidate materials and processes involved in protective die surface coating procedures by sputter deposition, using ion beam technologies, are discussed. Various pre-test results show that none of the coatings remained completely intact for 15,000 test cycles. The longest lifetime was observed for coatings such as tungsten, platinum, and molybdenum which reduced thermal fatigue, but exhibited oxidation and suppressed crack initiation only as long as the coating did not fracture. Final test results confirmed earlier findings and coatings with Pt and W proved to be the candidate materials to be used on a die surface to increase die life. In the W-coated specimens, which remained intact on the surface after thermal fatigue testing, no oxidation was found under the coating, although a few cracks formed on the surface where the coating broke down. Further research is planned.

    Full Text Available Abstract Background Interventions to increase physical activity and reduce sedentary behaviours within the workplace have been previously investigated. However, the evolution of these constructs without intervention has not been well documented. This retrospective study explored the natural progression or time kinetics of physical activity, sedentary behaviours and quality of life in a professional skilled workplace where focussed interventions were lacking. Methods Participants (n = 346 employed as full-time staff members at a regional university completed an online survey in 2013 assessing physical activity and sedentary behaviours via the International Physical Activity Questionnaire, and quality of life via the Short-Form 36v2 questionnaire. Differences between that cohort of participants and an initial sample of similar participants (2009, n = 297, accounting for gender and staff categories (academic vs. professional, were examined using ANCOVAs with working hours as a co-variate. Results In comparison to the initial cohort, the follow-up cohort reported significantly less leisure-time, total walking, total vigorous and total physical activity levels, and lower overall physical health for quality of life (p < 0.05. In contrast, the follow-up cohort reported a significantly greater weekly sitting time, greater mental health scores for quality of life and greater total moderate physical activity levels (p < 0.05 compared to the initial cohort. Conclusions Over a 4-year timeframe and without focussed workplace interventions, total physical activity levels were lower with sedentary behaviours greater at a rate twice that reported previously. Continuation of these undesirable health behaviours may impact negatively on worker productivity and health at a greater rate than that currently reported. Workplace interventions targeting sedentary behaviours and physical activity should be actively incorporated into organisations to

    There is a rapid increase in the population of the elderly globally, and Malaysia is anticipated to become an ageing nation in 2030. Maintaining health, social participation, reducing institutionalization, and improving quality of life of the elderly are public health challenges of the 21(st) century. Quality of life among elderly in Elderly Homes in Malaysia is under researched. This study aims to determine the quality of life and its associated factors among the Elderly in Elderly Homes in Kuala Lumpur. This was a cross-sectional study among 203 residents aged 60 years or more in eight randomly selected Elderly Homes in Kuala Lumpur in September 2014. Stratified simple random sampling was used to select participants. Study instruments included World Health Organization Quality of Life Questionnaire-Brief Version (WHOQOL-BREF), Multidimensional Scale for Perceived Social Support, and a questionnaire for Socio-demographic variables. Data collection was by face to face interview. Univariate and Multivariate analysis were used to determine associations, and P-value age, gender, level of education, economic status, outdoor leisure activity, physical activity, duration of residence, type of accommodation, co-morbidities, and social support. This study confirms that multiple factors are associated with quality of life among elderly in elderly homes. Social support, chronic co-morbidities, gender and outdoor leisure activity were significantly associated with all the domains of quality of life. Among the four domains of quality of life, the physical domain had the highest score while the social domain had the lowest score. This emphasizes the need for more social support-related interventions in these homes.

    Sleep disturbance is common and may adversely affect treatment outcome, mental health, and quality of life in heroin-dependent patients. Previous studies have focused upon patients receiving treatment. We conducted a cross-sectional descriptive study to explore the 1-month prevalence of sleep disturbance and its associations with socio-demographic, substance-related characteristics, severity of dependence, severity of depression, and quality of life among heroin-dependent patients before entering treatment program. The sample (n = 514) comprised individuals with heroin dependence attending the methadone maintenance treatment program and the therapeutic community at a psychiatric center in Nantou, Taiwan between 2008 and 2014. Sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI) with a global score greater than 5 indicating sleep disturbance. Centre for Epidemiologic Studies Depression Scale, Severity of Dependence Scale, and World Health Organization Quality of Life-BREF were also approached. T-test, chi-square tests, and multivariate logistic regression were performed to measure associations between variables and sleep disturbance. The 1-month prevalence of sleep disturbance (PSQI > 5) was 76.3% among 514 subjects with heroin dependence. Heroin users with sleep disturbance had significantly more life events in the previous year, higher rate of unemployment, greater cigarette consumption, more substance related criminal convictions, longer length of heroin use, higher rate of injectors, greater severity of dependence, greater severity of depression, and lower quality of life compared to those without sleep disturbance. Severity of dependence, severity of depression, and physical health domain of quality of life remained significantly associated with sleep disturbance after adjusting for other variables. Heroin-dependent patients had a high 1-month prevalence of sleep disturbance, and this was associated with greater severity of dependence

    The process of ageing influences all dimensions of social life and personal well-being, but the influence of health on different dimensions of quality of life (QoL) among the elderly is rarely examined. The aim of the pilot study is to test the feasibility of a comprehensive study design to evaluate general and dental health as well as QoL in a bi-national sample. In addition, this pilot study should allow for the exploration of potential interactions between QoL, socioeconomic, health and oral health variables. Individuals aged 64 years and older (n = 100) from university dental clinics of the Wroclaw Medical University, Poland (n = 50) and of the University Hospital in Dresden, Germany (n = 50) were examined. The oral health status of participants was assessed by clinical examination. Socio-demographic, environmental and general health status were evaluated during the medical interview. General quality of life (GQoL) was assessed by an overall question with a visual analogue scale (VAS) from -5 (worst) to +5 (best). Health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) were measured with the EQ-5D and OHIP-14 questionnaires. Statistical analyses comprised Pearson's c2 test, Wilcoxon test, linear regression model for statistical analysis and different multivariate linear regression analyses. For the GQoL-VAS-Score the results for QoL measurements were 1.22 ± 2.62 (x± SD), for EQ-5D-Score 7.45 ± 2.25 (x± SD), and for OHIP-14-ADD-Score 11.04 ± 13.56 (x± SD). Differences between Polish and German populations were observed. The study design proved to be feasible for a senior population. The overall GQoL question, EQ-5D and OHIP-14 were regarded as appropriate instruments. Subjective and objective (oral) health measures showed differences between Germany and Poland. For methodological reasons, these differences are not generalizable, but of value for study hypotheses in larger samples.

    Lithium-ion batteries are receiving considerable attention for large-scale energy-storage systems. However, to date the current cathode/anode system cannot satisfy safety, cost, and performance requirements for such applications. Here, a lithium-ion full battery based on the combination of a Li 3 VO 4 anode with a LiNi 0.5 Mn 1.5 O 4 cathode is reported, which displays a better performance than existing systems. Carbon-coated Li 3 VO 4 spheres comprising nanoscale carbon-coating primary particles are synthesized by a morphology-inheritance route. The observed high capacity combined with excellent sample stability and high rate capability of carbon-coated Li 3 VO 4 spheres is superior to other insertion anode materials. A high-performance full lithium-ion battery is fabricated by using the carbon-coated Li 3 VO 4 spheres as the anode and LiNi 0.5 Mn 1.5 O 4 spheres as the cathode; such a cell shows an estimated practical energy density of 205 W h kg -1 with greatly improved properties such as pronounced long-term cyclability, and rapid charge and discharge. © 2017 WILEY-VCH Verlag GmbH & Co.

    Quality of life and mental health of patients with severe heart failure with or without technical support for the left cardiac ventricle - a cross-sectional study Objectives: Chronic heart failure is associated with reduced quality of life (QoL) and poor prognosis. Support via a left ventricular assist device (LVAD) is an alternative to optimised medical management for patients with advanced heart failure. This study evaluated health-related QoL with both therapy options. In this consecutive cross-sectional study, patients with LVAD support (n = 50) and patients with optimised medical management (n = 50) were interviewed comprehensively about various domains of QoL, emotional stress, perceived self-efficacy, social support, life satisfaction, and communication. LVAD patients had a better overall QoL (KCCQ, clinical summary: MW: 67.4 vs. 52.9). Patients with medical management reported increased emotional stress stemming from depressed mood (HADS-D, MW: 7.1 vs.MW: 6.0). Depressed mood proved to be the most significant negative predictor for health-related QoL as well as for emotional well-being. Although they had a worse clinical situation preoperatively, LVAD patients had a significantly better QoL in both physical dimensions and functional competencies as well as significantly less psychological stress through depressed mood and anxiety.

    Improving the resiliency of healthcare workers is a national imperative, driven in part by healthcare workers having minimal exposure to the skills and culture to achieve work-life balance (WLB). Regardless of current policies, healthcare workers feel compelled to work more and take less time to recover from work. Satisfaction with WLB has been measured, as has work-life conflict, but how frequently healthcare workers engage in specific WLB behaviours is rarely assessed. Measurement of behaviours may have advantages over measurement of perceptions; behaviours more accurately reflect WLB and can be targeted by leaders for improvement. 1. To describe a novel survey scale for evaluating work-life climate based on specific behavioural frequencies in healthcare workers.2. To evaluate the scale's psychometric properties and provide benchmarking data from a large healthcare system.3. To investigate associations between work-life climate, teamwork climate and safety climate.

    Both the beneficial relationship between exercise and quality of life and the important role played by exercise self-efficacy in maintaining an exercise regimen among individuals with chronic heart failure are well known. However, most nursing interventions for Korean patients with chronic heart failure focus only on providing education related to risk factors and symptoms. Little information is available regarding the influence of physical functions, physical activity, and exercise self-efficacy on quality of life. This study was conducted to examine the impact of physical functioning, physical activity, and exercise self-efficacy on quality of life among individuals with chronic heart failure. This study used a cross-sectional descriptive design. Data were collected from 116 outpatients with chronic heart failure in Korea. Left ventricular ejection fraction and New York Heart Association classifications were chart reviewed. Information pertaining to levels of physical activity, exercise self-efficacy, and quality of life were collected using self-administered questionnaires. Data were analyzed using descriptive statistics, t tests, analyses of variance, correlations, and hierarchical multiple regressions. About 60% of participants were physically inactive, and most showed relatively low exercise self-efficacy. The mean quality-of-life score was 80.09. The significant correlates for quality of life were poverty, functional status, physical inactivity, and exercise self-efficacy. Collectively, these four variables accounted for 50% of the observed total variance in quality of life. Approaches that focus on enhancing exercise self-efficacy may improve patient-centered outcomes in those with chronic heart failure. In light of the low level of exercise self-efficacy reported and the demonstrated ability of this factor to predict quality of life, the development of effective strategies to enhance exercise self-efficacy offers a novel and effective approach to improving

    Past research provides strong evidence that adverse life events heighten the risk of delinquent behavior among adolescents. Urban informal (slum) settlements in sub-Saharan Africa are marked by extreme adversity. However, the prevalence and consequences of adverse life events as well as protective factors that can mitigate the effects of exposure to these events in slum settlements is largely understudied. We examine two research questions. First, are adverse life events experienced at the individual and household level associated with a higher likelihood of delinquent behavior among adolescents living in two slums in Nairobi, Kenya? Second, are parental monitoring, religiosity, and self-esteem protective against delinquency in a context of high adversity? We used cross-sectional data from 3,064 males and females aged 12-19 years who participated in the Transitions to Adulthood Study. We examined the extent to which a composite index of adverse life events was associated with delinquent behavior (measured using a composite index derived from nine items). We also examined the direct and moderating effects of three protective factors: parental monitoring, religiosity, and self-esteem. Fifty-four percent of adolescents reported at least one adverse life event, while 18% reported three or more adverse events. For both males and females, adversity was positively and significantly associated with delinquency in bivariate and multivariate models. Negative associations were observed between the protective factors and delinquency. Significant adverse events × protective factor interaction terms were observed for parental monitoring (females and males), religiosity (males), and self-esteem (females). Similar to research in high income countries, adverse life events are associated with an increased likelihood of delinquent behavior among adolescents living in urban slums in Kenya, a low-income country. However, parental monitoring, religiosity, and self-esteem may

    Ascertaining individuals' quality of life and wellbeing is essential in public health and clinical research. The impact of these two pressing geriatric syndromes--impaired mobility and cognitive function--on wellbeing and quality of life is not well examined. Hence, our objective was to identify key clinically relevant outcome measures of mobility and cognitive function that explain variation in wellbeing and health related quality of life (HRQoL) among community dwelling older adults. We conducted a cross-sectional analysis of 229 participants presenting to the Vancouver Falls Prevention Clinic from June 2010 through October 2013. The linear regression models included two dependent variables: the ICECAP-O assessing wellbeing and the EQ-5D-3L assessing HRQoL. Key independent variables included the Short Performance Physical Battery (SPPB) and the Montreal Cognitive Assessment (MoCA). Covariates included Functional Comorbidity Index (FCI), sex and age. In the two multiple linear regression models, age was statistically controlled. Other covariates (i.e., sex and FCI) were included based on statistical significance (i.e., p quality of life (p > 0.05). We found that a measure of mobility and balance was associated with HRQoL and wellbeing. However, cognitive function was associated with wellbeing only. This study highlights the potential importance of considering wellbeing as an outcome measure if interventions are intended to have a broader impact than health alone.

    Measurement of quality of life among prostate cancer patients helps the health care providers to understand the impact of the disease in the patients' own perspective. The main aim of this study is to measure the quality of life among prostate cancer patients at University Malaya Medical Center (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and to ascertain the association factors for physical coefficient summary (PCS) and mental coefficient summary (MCS). A hospital based, cross sectional study using the Short Form-36 (SF-36) questionnaire was conducted over a period of 6 months. A total of 193 respondents were recruited. Their total quality of life score was 70.1± 14.7 and the PCS score was lower compared to MCS. The factors associated for PCS were: age, living partner, renal problem, urinary problem of intermittency, dysuria and hematuria. Factors associated for MCS were: age, living partner, renal problem, presenting prostatic specific antigen and urinary problem of intermittency and dysuria. Our prostate cancer patients had moderate quality of life in the physical health components but their mental health was less affected.

    1993-01-01

    Hard, wear resistant and low friction coatings are presently produced on a world-wide basis, by different processes such as electrochemical or electroless methods, spray technologies, thermochemical, CVD and PVD. Some of the most advanced processes, especially those dedicated to thin film depositions, basically belong to CVD or PVD technologies, and will be looked at in more detail. The hard coatings mainly consist of oxides, nitrides, carbides, borides or carbon. Over the years, many processes have been developed which are variations and/or combinations of the basic CVD and PVD methods. The main difference between these two families of deposition techniques is that the CVD is an elevated temperature process (≥ 700 C), while the PVD on the contrary, is rather a low temperature process (≤ 500 C); this of course influences the choice of substrates and properties of the coating/substrate systems. Fundamental aspects of the vapor phase deposition techniques and some of their influences on coating properties will be discussed, as well as the very important interactions between deposit and substrate: diffusions, internal stress, etc. Advantages and limitations of CVD and PVD respectively will briefly be reviewed and examples of applications of the layers will be given. Parallel to the development and permanent updating of surface modification technologies, an effort was made to create novel characterisation methods. A close look will be given to the coating adherence control by means of the scratch test, at the coating hardness measurement by means of nanoindentation, at the coating wear resistance by means of a pin-on-disc tribometer, and at the surface quality evaluation by Atomic Force Microscopy (AFM). Finally, main important trends will be highlighted. (orig.)

    Full Text Available Dysmenorrhea is a notably serious crisis among young adult girls and it distresses their quality of life. After menarche, most young adult girls suffer severe pain, irregular menses, too much bleeding, and dysmenorrhea. It is a common gynecological complication affecting more than half of the young adult girls resulting in episodic school absenteeism coupled with a negative impact on social behavior, educational, and sports activities. This study was a cross-sectional descriptive, conducted from September to November 2013 among 210 young adult, female medical students of Management and Science University, using a semi-structured questionnaire. The questionnaire used in this study was associated with the health-related quality of life among young adult girls; questions were related to demography, family menstrual history, prevalence, symptoms, absentees of school, involvement in sports activities, and self-care strategies. This survey was completed and the data was analyzed for the results with percentages and chi-square test applied.

    The objective of the following study is to assess parent reported quality of life (QOL) in children with epilepsy and to assess the demographic and clinical factors, which influence the QOL in children with epilepsy. We consecutively enrolled 40 children aged from 2 years to 14 years with active epilepsy who had undergone a comprehensive evaluation for epilepsy. Parents were enquired on baseline demographic variables including age, gender, socio-economic status and parental education. Clinical details of epilepsy including the type of epilepsy, seizure frequency were assessed. QOL was evaluated with the parent reported quality of life in childhood epilepsy (QOLCE) questionnaire. A total of 40 children were enrolled of which 55% (22/40) were males and the mean (standard deviation [SD]) age of enrolled children was 10.6 (2.7) years. The majority came from a rural background (80% [32/40]), were from lower (15 [37.5%]) or middle (23 [57.5%]) socio-economic status, with almost half (22 [55%]) of mothers being educated until high school. The overall mean (SD) QOL score was 66.7 (4.83). Lowest mean (SD) scores were observed in self-esteem (45.2 [7.3]) subscale and subscales with higher QOL scores included control/helplessness (82.1 [8.51]), anxiety (81.6 [12.55]) and social stigma (95.0 [11.6]). Parental education, socio-economic status (P = 0.96), frequency of seizure (P = 0.34) or type of epilepsy (P = 0.92) did not significantly affect the overall QOL among children with epilepsy. Our study concluded that overall QOL was compromised in Indian children with epilepsy. Demographic factors like parental education, socio-economic status and clinical factors like frequency of seizure or type of seizure did not significantly affect the QOL of epileptic children.

    To compare quality of life (QOL) according to ambulatory status and to investigate association with habitual physical activity (HPA) in children with cerebral palsy (CP) aged 5 years. Fifty-eight participants were classified using Gross Motor Function Classification System (GMFCS) as level I = 33, II = 8, III = 6, IV = 3 and V = 8 and assessed for motor function using 66-item Gross Motor Function Measure (GMFM-66). Participants wore an ActiGraph ® triaxial accelerometer for 3 days to measure HPA. Parents completed the parent proxy Cerebral Palsy Quality of Life questionnaire for Children (CP QOL-Child). Linear regression analyses were performed. Ambulant children with CP (GMFCS I-III) had better parent-reported QOL than non-ambulant children (GMFCS IV-V) in domains of feelings about functioning (mean difference (MD) = 20.0; 95% confidence interval (CI) = 11.7, 28.2), participation and physical health (MD = 14.5; 95%CI = 4.7, 24.4), and emotional well-being and self-esteem (MD = 12.5; 95%CI = 4.8, 20.1). HPA was not associated with QOL domains after controlling for motor function. GMFM scores accounted for 39% of variation for feelings about functioning domain (MD = 0.4; 95%CI = 0.2, 0.6).

    Patients with congenital diaphragmatic hernia (CDH) have a high residual morbidity rate. We compared self-reported health-related quality of life (HRQoL) between patients with CDH and healthy children. Forty-five patients with CDH who were born from January 1, 1990, through February 15, 2015, were matched to healthy, age-matched control participants at a 1:2 ratio. The health records of the study participants were reviewed to determine comorbid conditions, and HRQoL was assessed by both the participants and their parents with the Pediatric Quality of Life Inventory (PedsQL). The HRQoL scores of the patients with CDH and the control participants were compared by using analysis of variance to adjust for age group and sex. Among patients with CDH, analysis of variance was used to compare HRQoL scores across groups defined according to their characteristics at initial hospitalization, postdischarge events, and comorbid conditions. Compared with control participants, patients with CDH had lower mean PedsQL scores, as reported by the parent and child, for the physical and psychosocial domains (P CDH, low HRQoL was associated with chronic respiratory issues. Patients with CDH had lower HRQoL compared with healthy participants. Parent-reported HRQoL tended to be higher than child-reported HRQoL. Results were also inconsistent for the risk factors associated with HRQoL obtained by using child- and parent-reported scores. Therefore, when interpreting HRQoL in CDH survivors, a proxy report should not be considered a substitute for a child's self-report.

    Full Text Available Develop a set equipment for plasma forming ceramic coatings. The article presents characteristics and parameters of the developed complex equipment for formation of plasma ceramic coatings as well as results of its testing. Methods of research is based on studies of structural elements composite plasma coatings system ZrO2 – Y2O3  obtained  using  developed complex equipment. One of the most effective ways to protect the components from high temperature corrosion and oxidation is formation on the surface of plasma thermal barrier coatings. For thermal barrier coating has very strict requirements: сharacterized by a smooth change of physico-mechanical properties (porosity, microhardness, elastic modulus in the cross section of the metal substrate to the outer ceramic layer; to withstand multiple cycles of thermal cycling from room temperature to the operating temperature; to maintain gastightness under operating conditions and thus ensure a sufficiently high level of adhesive strength. For realization of new technological schemes applying thermal barrier coatings with high operational characteristics was developed, patented and manufactured a range of new equipment. The experiments show that authors developed PBG-1 plasmatron and powder feeder PPBG-04 have at least 2–3 times the service life during the deposition of ceramic materials compared to the standard equipment of the company "Plasma-Technik", by changing the structure of the cathode-anode plasma torch assembly and construction of the delivery unit of the feeder to facilitate the uniform supply of the powder into the plasma jet and the best of his penetration. The result is better plasma coatings with improved operational characteristics: adhesion strength is increased to 1.3–2 times, material utilization in 1.5–1.6 times microhardness 1.2–1.4 times the porosity is reduced by 2–2.5 times.

    There is a paucity of research on the nature of life adversity in depressed and non-depressed older adults. Early life events work used in-depth interviews; however, larger epidemiological trials investigate life adversity using brief questionnaires. This study investigates the type of life adversity experienced in later life and its association with depression and compares adversity captured using a brief (LTE-Q) and in-depth (LEDS) measure. 960 participants over 65 years were recruited in UK primary care to complete the PHQ-9 and LTE-Q. A sub-sample (n=19) completed the LEDS and a question exploring the subjective experience of the LTE-Q and LEDS. Important life adversity was reported on the LTE-Q in 48% of the sample. In the LTE-Q sample the prevalence of depression (PHQ-9≥10) was 12%. Exposure to recent adversity was associated with doubling of the odds of depression. The LTE-Q only captured a proportion of adversity measured by the LEDS (42% vs 84%). Both measures showed health, bereavement and relationship events were most common. The cross-sectional design limits the extent to which inferences can be drawn around the direction of causality between adversity and depression. Recall in older adults is questionable. UK older adults face adversity in areas of health, bereavement and relationships which are associated with depression. This has clinical relevance for psychological interventions for older adults to consider social context and social support. It helps identify the strengths and weaknesses of a brief adversity measure in large scale research. Further research is needed to explore the mechanisms of onset and direction of causality.

    Carboxymethyl cellulose (CMC) coatings alone and in combination with gamma irradiation was tested for maintaining the storage quality and extending shelf-life of plum. Matured green plums were CMC coated at levels 0.5–1.0% w/v and gamma irradiated at 1.5 kGy. The treated fruit including control was stored under ambient (temperature 25±2 °C, RH 70%) and refrigerated (temperature 3±1 °C, RH 80%) conditions. In fruits treated with individual treatments of 1.0% w/v CMC; 1.5 kGy irradiation and combination of 1.0% w/v CMC and 1.5 kGy irradiation, no decay was recorded up to 11, 17 and 21 days of ambient storage. Irradiation alone at 1.5 kGy gave 8 days extension in shelf-life of plum compared to 5 days by 1.0% w/v CMC coating following 45 days of refrigeration. All combinatory treatments of CMC coating and irradiation proved beneficial in maintaining the storage quality as well as delaying the decaying of plum during post-refrigerated storage at 25±2 °C, RH 70% but, combination of CMC at 1.0% w/v and 1.5 kGy irradiation was found significantly (p≤0.05) superior to all other treatments in maintaining the storage quality and delaying the decaying of plum. CMC coating of plums at 1.0% w/v followed by irradiation at 1.5 kGy resulted in chlorophyll retention of 19.4% after 16 days compared to 10% in control after 8 days of ambient storage. Under refrigerated conditions, same treatment gave retention of 67.6% in chlorophyll compared to 10.6% in control after 35 days of storage. The above combinatory treatment resulted in extension of 11 days in shelf-life of plum during post-refrigerated storage at 25±2 °C, RH 70% following 45 days of refrigeration. Based on microbial analysis, irradiation alone at 1.5 kGy and in combination with 1.0% w/v CMC resulted in 2.0 and 1.8 log reduction in yeast and mold count of plum fruit after 20 and 35 days of ambient and refrigerated storage, thereby ensuring consumer safety. - Highlights: • Irradiation and CMC alone at 1.5 k

    General Magnaplate Corporation's pharmaceutical machine is used in the industry for high speed pressing of pills and capsules. Machine is automatic system for molding glycerine suppositories. These machines are typical of many types of drug production and packaging equipment whose metal parts are treated with space spinoff coatings that promote general machine efficiency and contribute to compliance with stringent federal sanitation codes for pharmaceutical manufacture. Collectively known as "synergistic" coatings, these dry lubricants are bonded to a variety of metals to form an extremely hard slippery surface with long lasting self lubrication. The coatings offer multiple advantages; they cannot chip, peel or be rubbed off. They protect machine parts from corrosion and wear longer, lowering maintenance cost and reduce undesired heat caused by power-robbing friction.

    Quality of life (QoL) is one major outcome parameter in the care for people with dementia (PwD); however, their assessment is lacking a gold standard. The purpose of this study was to evaluate potential factors associated with nurse-rated quality of life of PwD in nursing homes in Berlin, Germany. An explorative cross-sectional study was performed in five nursing homes to evaluate QoL. Nurses rated the QoL for all residents with dementia by completing two different standardised assessments (ADRQL, QUALIDEM). Potential associated factors were evaluated concerning resident and nurse related factors. A fixed-effects models of analysis of co-variance (ANCOVA) was used to analyse effects of assumed associated factors of the major outcome parameters ADRQL and QUALIDEM. Associated factors were severity of dementia (GDS), challenging behaviour (CMAI), and other characteristics. Regarding the nurses, burnout (MBI), satisfaction with life (SWLS), attitude (ADQ) and empathy toward residents (JSPE), as well as circumstances of the ratings and days worked in advance of the ratings were assessed. In total, 133 PwD and 88 nurses were included. Overall, the ratings show moderate to high QoL in every subscale independent of the instrument used. Assumed confounders relevantly influenced 14 out of 17 ratings. Predominantly, residents' challenging behaviour, nurses' burnout and satisfaction with life as well as the circumstances of the ratings are significant and clinically relevant associated factors. Assessing QoL of PwD is acknowledged as a central component of health care and health care research. In later stages of dementia, proxy-reported information obtained from quality of life questionnaires is and will continue to be essential in this research. However, methodological issues that underline this research - matters of measurement and instrument validity - must receive more attention. Associated factors in proxy-ratings have to be routinely assessed in order to get more valid

    Despite having the capability of achieving high energy densities, Li-O2 batteries still suffer from many inherent disadvantages such as electrolyte stability, sluggish kinetics of the oxygen reduction/evolution reactions in the aprotic environment and electrodes stability. Our research demonstrates by combining electrochemical and analytical techniques that the performances of Li-O2 batteries based on LiTFSI-Tetraglyme electrolyte and Au-coated carbon electrodes are manly hindered by the instability of the lithium metal anode in the oxygen-saturated environment. Although the Au-coated carbon electrodes are able to minimize side reactions arising from electrolyte decomposition, oxygen crossover on the lithium metal results in the formation of decomposition products (LiOH, Li2CO3) that are clearly detrimental for the battery performance. Finally it is demonstrated that the Au-coated carbon electrodes in combination with the LiTFSI-Tetraglyme electrolyte can sustain extended cycling (100 cycles) when a more stable source of Li-ion, namely lithium iron phosphate (LFP), is used.

    In recent years there has been a growing trend among students to travel for educational purposes to other countries where there is the possibility of experiencing considerable amounts of stress affecting their physical and mental functioning. The aims of the current study were to investigate the health related quality of life (HRQOL) of Nepalese students studying in South Korea to explore the relationship between HRQOL and perceived and acculturative stress, and to identify the determinants of HRQOL. One hundred and thirty students were enrolled in this study. HRQOL was assessed using the Medical Outcomes Study Short Forms (SF-12) questionnaire. Perceived stress and acculturative stress was measured using the Perceived Stress Scale and Acculturative Stress Scale for international students, respectively. Pearson's correlation test and multiple regression analysis were performed. Perceived stress and acculturative stress were negatively correlated with HRQOL. The highest value in the HRQOL was reported for the vitality subscale and the lowest value was reported for the role-emotional. In the regression model, perceived stress, acculturative stress, relationship with advisor, and marital status accounted for a significant (p students studying in South Korea experience a considerable amount of perceived and acculturative stress, which is negatively related with their HRQOL. Provision of culture specific counseling and orientation programs may benefit the students. The determinants of HRQOL identified in this study were perceived stress, acculturative stress, relationship with advisor, and marital status.

    To evaluate the factors associated with the perceptions of oral health-related quality of life (OHRQoL) in children and preadolescents. 167 students aged 8-14 years were recruited from the public schools of Piracicaba, Brazil. Participants were examined for caries, gingivitis, fluorosis, malocclusions and signs and symptoms of temporomandibular disorders (TMD). OHRQoL was measured using the Brazilian Portuguese version of the Child Perceptions Questionnaire (CPQ 8-10 and 11-14), where higher scores indicate worse OHRQoL. Symptoms of anxiety and depression were evaluated using self-applied questionnaires. Sociodemographic characteristics, dental history and oral hygiene habits were evaluated using a questionnaire. Bivariate and multivariate analyses were used to identify the variables associated with CPQ scores. Higher CPQ 8-10 scores were associated with fluorosis, TMD and symptoms of anxiety and depression. Higher CPQ 11-14 scores were associated with females, TMD and symptoms of anxiety and depression. Younger children (OR=0.32, pPoor OHRQoL was associated with TMD (OR=4.29, poral diseases and disorders as well as psychological phenomena, such as anxiety and depression, influenced oral health outcomes in this group of children and preadolescents.

    This study assessed the prevalence of personality disorders (PDs), according to DSM-IV criteria, in relation to depressive symptomatology at three different periods of life in female subjects. Depressive symptoms and personality disorders were assessed in a sample of 568 women from three different transitional stages: 134 students, 314 primiparous women after childbirth and 120 women diagnosed with breast cancer. Depressive symptoms were assessed by the Hospital Depression and Anxiety Scale in the first and third groups and by the Edinburgh Post-natal Depression Scale in the second group, whereas PDs were assessed by the French version of the Vragenlijst voor Kenmerken van de Persoonlijkheid. Depressive symptomatology and rates of PD (20.4% and 6.3%) were equivalent in the three groups. The prevalence of PD was higher in the depressed group compared with the non-depressed group, with more paranoid, borderline, avoidant, obsessive-compulsive, schizotypal, antisocial, dependent and histrionic PD. Our findings support the hypothesis that PDs are more frequently associated with depressive symptoms. Borderline and avoidant PDs were more prevalent among young women. All cluster C PD (dependent, avoidant and obsessive-compulsive) co-occurred significantly with depressive symptoms. Copyright © 2013 John Wiley & Sons, Ltd.

    The application of electrostatics in both powder and liquid coating can improve the quality of food, such as its appearance, aroma, taste, and shelf life. Coatings can be found most commonly in the snack food industry, as well as in confectionery, bakery, meat and cheese processing. In electrostatic powder coating, the most important factors influencing coating quality are powder particle size, density, flowability, charge, and resistivity, as well as the surface properties and characteristics of the target. The most important factors during electrostatic liquid coating, also known as electrohydrodynamic coating, include applied voltage and electrical resistivity and viscosity of the liquid. A good understanding of these factors is needed for the design of optimal coating systems for food processing.

    Environmental barrier coatings (EBCs) and SiCSiC ceramic matrix composites (CMCs) systems will play a crucial role in next generation turbine engines for hot-section component applications because of their ability to significantly increase engine operating temperatures with improved efficiency, reduce engine weight and cooling requirements. The development of prime-reliant environmental barrier coatings is essential to the viability and reliability of the envisioned CMC engine component applications, ensuring integrated EBC-CMC system durability and designs are achievable for successful applications of the game-changing component technologies and lifing methodologies.This paper will emphasize recent NASA environmental barrier coating developments for SiCSiC turbine airfoil components, utilizing advanced coating compositions, state-of-the-art processing methods, and combined mechanical and environment testing and durability evaluations. The coating-CMC degradations in the engine fatigue-creep and operating environments are particularly complex; one of the important coating development aspects is to better understand engine environmental interactions and coating life debits, and we have particularly addressed the effect of Calcium-Magnesium-Alumino-Silicate (CMAS) from road sand or volcano-ash deposits on the durability of the environmental barrier coating systems, and how the temperature capability, stability and cyclic life of the candidate rare earth oxide and silicate coating systems will be impacted in the presence of the CMAS at high temperatures and under simulated heat flux conditions. Advanced environmental barrier coating systems, including HfO2-Si with rare earth dopant based bond coat systems, will be discussed for the performance improvements to achieve better temperature capability and CMAS resistance for future engine operating conditions.

    The aim of this study was to investigate the oral health-related quality of life (OHRQoL) among subjects with typical, atypically positive, and atypically negative personality trait scores within the five basic dimensions of personality (neuroticism, extroversion, openness, agreeableness, and conscientiousness). A total of 235 subjects not seeking dental treatment were recruited from the families and acquaintances of dental students from the University of Salamanca. The 14-item Oral Health Impact Profile (OHIP-14) was used to capture the impact on their OHRQoL. The Neouroticism-Extroversion-Openness Personality Inventory Revised was applied to assess personality profiles. People were classified as having negatively atypical, typical, or positively atypical (PAP) personality, depending on whether the sum of the Z scores was 1, respectively. Pearson correlation, analysis of variance, and logistic regression test were used for the statistical analyses. The sample was comprised of highly educated adults (aged 18-80 years) with good oral health habits. PAP subjects suffered significantly more in the dimension of psychologic discomfort (0.6 ± 0.7) than did their counterparts (0.3 ± 0.6), but the global impact in OHRQoL was comparable. Personality was weakly correlated with OHIP-14. The perception of dental treatment needs was found to be the major predictor of the impact on OHRQoL, but the number of negatively atypical deviated personality traits and the agreeableness raw score also had an effect. The risk of perceiving an impact on OHRQoL is significantly higher in individuals perceiving treatment needs and increases proportionally to the number of negatively atypical personality traits.

    Hemodialysis (HD) has a severe impact on the life of HD patients. The aim of this work was to assess the prevalence of depression and anxiety disorders, suicidal ideation, and the quality of life among HD patients. Associated factors were also studied. A cross-sectional study was carried out among 103 HD patients treated at the HD Center of Al Farabi Hospital of Oujda during a period of six months in 2015. The Mini-International Neuropsychiatric Interview and European Quality of Life-5 Dimensions (EQ-5D) were used for the assessment. Major depressive episode (MDE) was found in 34% of our patients, whereas anxiety disorder was observed in 25.2%. Suicidal ideation was found in 16.5% and 1.9% of our patients planned their suicide. The EQ-5D index was 0.41 ± 0.36 and the EQ-Visual Analog Scale score was 45.73 ± 14. Multivariate analysis showed that MDEs were associated with three factors: marital status, pain, and anxiety disorder. There was also an association between anxiety disorder and age and EQ-Visual Analog Scale score. Suicidal ideation was associated with marital status and anxiety disorders. Together, these results underline the importance of the collaboration between nephrologists and psychiatrists for a better care of HD patients.

    The aim is to examine the acculturation level of international nurses working in a multi-cultural society. The relationship between acculturation, working environment and quality of life of international nurses was also explored. A cross-sectional, correlational study using self-report questionnaire was conducted on 814 international nurses using stratified random sampling based on the nationality distribution of international nurses registered with the Singapore Nursing Board. Outcome measures included World Health Organisation Quality of Life-BREF (WHOQOL_BREF) and Practice Environment Scale of the Nursing Work Index-Revised (PES-NWI-R). Data were collected from June to December 2012. There were variations in the acculturation level among different nationality groups of international nurses. Acculturation levels were the lowest among Mainland Chinese international nurses (M=27.47, SD 5.23). A positive correlation was found between acculturation and quality of life whereas a lower perception of work environment was associated with lower acculturation level. Data obtained from this study can be utilized to develop interventions targeted at the unique needs of the international nurses as they migrate. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Health-related quality of life (QOL is reported to be reduced during pregnancy. Associations between QOL, physical activity (PA, insomnia, depression and worry are insufficiently investigated among pregnant women. The aim of this study was to evaluate QOL and PA patterns among healthy pregnant women, and to examine how QOL might correlate to PA, sleep, worry and depression. This is an observational cross-sectional study, conducted among a convenient sample of 141 healthy pregnant women using five questionnaires: WHOQOL-brief (WHO quality of life questionnaire, brief version, ISI (Insomnia Severity Index, PSWQ (Penn State Worry Questionnaire, ZSRDS (Zung Self-Rating Depression Scale, and Pregnancy Physical Activity Questionnaire (PPAQ. Pre-gestational BMI was inversely correlated to overall health while education was positively correlated to psychological health, social relationships and environment domains. Smoking before and during pregnancy significantly impacted the general health and psychological health. Total and light PA were positively correlated to psychological health and social relationships. Sports/exercise showed positive correlations with several QOL domains. Insomnia and depression were significantly associated with a decrease in all domains of QOL, while worries were associated with a decrease in physical, psychological and environmental domains. There were significant negative correlations between ZSRDS scores and total activity. PA, worries, depression and insomnia affected QOL during pregnancy. Furthermore, pregnant women presenting depression had a reduced total PA. Sleep and mental health as well as encouraging PA during pregnancy are necessary to improve the quality of life of pregnant women.

    Young adolescents with scoliosis are more likely than adults to experience psychological distress affecting health-related quality of life (HRQoL). Adolescence is a sensitive period of psychological development, and thus physical deformity from scoliosis can negatively affect body image and appearance of adolescents. The present study evaluated HRQoL in young Korean adolescents with idiopathic scoliosis and identified related factors. One hundred and ten adolescents with idiopathic scoliosis were recruited from two tertiary hospital outpatient clinics over one year. HRQoL was measured using the Korean version of the Scoliosis Research Society 22 revision (SRS-22r) questionnaire. In addition, participant medical records were reviewed to collect data on severity of scoliosis, type of treatment and age at which they were first diagnosed with the disease. The mean age of the participants was 14.2 years and 48.2 % were first diagnosed at 9-12 years. Most participants (61.8 %) were under observation to follow up the curvature progression and 20.9 % received regular physiotherapy. Almost half the participants (47.3 %) had mild (10°-25°), 41.8 % moderate (25°-40°), and 10.9 % severe (>40°) scoliosis. The total score of the SRS-22r differed significantly between the groups of age at diagnosis (p = 0.033) and type of treatment (p = 0.025). Self-image, a sub-domain of the SRS 22r, was significantly lower in the severe curve deformity group than in the other groups (p = 0.031). An earlier age of scoliosis diagnosis and conservative treatment were related to higher HRQoL scores of Korean adolescents with scoliosis. Although the overall HRQoL did not significantly differ by severity of disease, self-image was significantly decreased in adolescents with severe spinal deformity. HRQoL of adolescent patients with idiopathic scoliosis can be affected by several factors that medical staff needs to consider in order to produce the best and most effective

    To assess oral status and self-reported oral health in community-living elderly and to determine differences between relevant subgroups of oral status (remaining teeth, edentulous, implant-retained overdentures) and case complexity (robust, frail, complex care needs). In this cross-sectional descriptive study, 1325 Dutch community-living elderly (≥75 years of age) were asked to complete validated questionnaires on frailty, activities of daily living (ADL), complexity of care needs, and QoL. Data on oral status, self-reported oral health, dental care, general health, and medication use were assessed. Differences between relevant subgroups were determined. Data of 1026 (77%) elderly (median 80 years, IQR 77-84) were analyzed: 39% had remaining teeth, 51% were edentulous, and 10% had implant-supported overdentures. Elderly with complex care needs (n = 225, 22%) and frail elderly (n = 217, 21%) were more often edentulous and reported more oral problems than robust elderly (n = 584, 57%). Elderly persons with remaining teeth were less frail, had better QoL and ADL, and used fewer medicines than edentulous elderly. Elderly with implant-supported overdentures performed better on frailty and QoL than edentulous elderly with conventional dentures. Community-living elderly commonly suffer from oral health problems, in particular elderly with complex care needs. QoL, ADL, and general health are higher among community-living elderly with remaining teeth and implant-supported overdentures than in edentulous elderly. © 2017 John Wiley & Sons A/S.

    Advanced environmental barrier coatings will play an increasingly important role in future gas turbine engines because of their ability to protect emerging light-weight SiC/SiC ceramic matrix composite (CMC) engine components, further raising engine operating temperatures and performance. Because the environmental barrier coating systems are critical to the performance, reliability and durability of these hot-section ceramic engine components, a prime-reliant coating system along with established life design methodology are required for the hot-section ceramic component insertion into engine service. In this paper, we have first summarized some observations of high temperature, high-heat-flux environmental degradation and failure mechanisms of environmental barrier coating systems in laboratory simulated engine environment tests. In particular, the coating surface cracking morphologies and associated subsequent delamination mechanisms under the engine level high-heat-flux, combustion steam, and mechanical creep and fatigue loading conditions will be discussed. The EBC compostion and archtechture improvements based on advanced high heat flux environmental testing, and the modeling advances based on the integrated Finite Element Analysis Micromechanics Analysis Code/Ceramics Analysis and Reliability Evaluation of Structures (FEAMAC/CARES) program will also be highlighted. The stochastic progressive damage simulation successfully predicts mud flat damage pattern in EBCs on coated 3-D specimens, and a 2-D model of through-the-thickness cross-section. A 2-parameter Weibull distribution was assumed in characterizing the coating layer stochastic strength response and the formation of damage was therefore modeled. The damage initiation and coalescence into progressively smaller mudflat crack cells was demonstrated. A coating life prediction framework may be realized by examining the surface crack initiation and delamination propagation in conjunction with environmental

    Full Text Available More than twenty years ago, hydroxyapatite (HA, calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical experience includes the implantation of more than 4,000 cementless hydroxyapatite coated hip prostheses since 1990. The models implanted are coated with HA in the acetabulum and in the metaphyseal area of the stem. The results corresponding to survival and stability of implants were very satisfactory in the long-term. From our experience, HA-coated hip implants are a reliable alternative which can achieve long term survival, provided that certain requirements are met: good design selection, sound choice of bearing surfaces based on patient life expectancy, meticulous surgical technique, and indications based on adequate bone quality.

    The purpose of this study is to investigate the association between polypharmacy with health-related quality of life (HRQoL) and medication regimen complexity with HRQoL in residential aged care facilities (RACFs). A cross-sectional study of 383 residents from six Australian RACFs was conducted. The primary exposures were polypharmacy (≥9 regular medications) and the validated Medication Regimen Complexity Index (MRCI). The outcome measure was staff informant rated quality of life assessed using the Quality of Life Alzheimer's disease (QoL-AD) scale. Covariates included age, sex, Charlson's comorbidity index, activities of daily living, and dementia severity. Logistic quantile regression was used to characterize the association between polypharmacy and QoL-AD (model 1) and MRCI and QoL-AD (model 2). The median age of the 383 residents was 88 years and 297 (78 %) residents were female. In total, 63 % of residents were exposed to polypharmacy and the median MRCI score (range) was 43.5 (4-113). After adjusting for the covariates, polypharmacy was not associated with either higher or lower QoL-AD scores (estimate -0.02; 95 % confidence interval (CI) -0.165, 0.124; p = 0.78). Similarly, after adjusting for the covariates, MRCI was not associated with either higher or lower QoL-AD scores (estimate -0.0009, 95 % CI -0.005, 0.003; p = 0.63). These findings suggest that polypharmacy and medication regimen complexity are not associated with staff informant rated HRQoL. Further research is needed to investigate how specific medication classes may impact change in quality of life over time.

    To examine the relationships of two screening instruments recently developed for assessment of exhaustion disorder (ED) with some other well-known inventories intended to assess ED-related concepts and self-reports of job demands, job control, job support, private life stressors, and personality factors. A cross-sectional population sample ( n = 1355) completed: the Karolinska Exhaustion Disorder Scale (KEDS), Self-reported Exhaustion Disorder Scale (s-ED), Shirom-Melamed Burnout Questionnaire (SMBQ), Utrecht Work Engagement Scale (UWES-9), Job Content Questionnaire (JCQ), Big Five Inventory (BFI), and items concerning family-to-work interference and stress in private life. Compared to participants without any indication of ED, participants classified as having ED on KEDS or s-ED had higher scores on all four SMBQ subscales, lower scores on the UWES-9 subscales vigor and dedication, higher JCQ job demands scores, lower JCQ job support scores, higher degrees of family-to-work interference and stress in private life, and higher BFI neuroticism and openness scores. In addition, participants classified as having ED on KEDS had lower scores on the UWES-9 absorption subscale, the JCQ job control scale, and lower BFI extraversion, agreeableness and conscientiousness scores, compared to the subgroup not classified as having ED. As expected, we observed an overall pattern of associations between the ED screening inventories KEDS and s-ED and measures of burnout, work engagement, job demands-control-support, stress in private life, family-to-work interference, and personality factors. The results suggest that instruments designed to assess burnout, work engagement, and ED share common ground, despite their conceptual differences.

    Full Text Available Abstract Background Measurement of health-related quality of life (HRQOL among patients with osteoarthritis (OA helps the health care provider to understand the impact of the disease in the patients' own perspective and make health services more patient-centered. The main aim of this study was to measure the quality of life among patients with symptomatic knee OA attending primary care clinic. We also aimed to ascertain the association between socio-demographic and medical status of patients with knee OA and their quality of life. Methods A clinic based, cross sectional study using the Short Form-36 (SF-36 questionnaire was conducted in two primary care health clinics in Hulu Langat, Selangor, Malaysia over a period of 8 months. The nurses and medical assistants were involved in recruiting the patients while the family physicians conducted the interview. Results A total 151 respondents were recruited. The mean age was 65.6 ± 10.8 years with females constituted 119 (78.8% of the patients. The mean duration of knee pain was 4.07 ± 2.96 years. Half of the patients were overweight and majority, 138 (91.4%, had at least one co-morbidity, the commonest being hypertension. The physical health status showed lower score as compared to mental health component. The domain concerning mental health components showed positive correlation with age. There was a significant negative correlation between age and physical functioning (p Conclusions This study has shown that patients with knee OA attending primary care clinics have relatively poor quality of life pertaining to the physical health components but less impact was seen on the patients' mental health.

    To evaluate the impact of morbid obesity on physical capacity, joint-related symptoms, and on the overall quality of life. Cross-sectional study carried out at a university hospital, enrolling 39 individuals admitted to a bariatric surgery service. Physical capacity was assessed by Six-Minute Walk Test (SMWT) and the Borg rating of perceived exertion (RPE). Knee-related symptoms were evaluated by Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Lysholm Score. Quality of life was evaluated by Short Form 36 Health Questionnaire (SF-36). On SMWT, the mean distance walked was 374.1±107.5 m. The mean Borg score was 12.9±2.4. KOOS questionnaire found the following scores: pain (64.3±24), other symptoms (67.2±25.5), function in daily living (60.4±26.8), function in sport and recreation (28.5±32.2), knee-related quality of life (35.9±33.5), mean Lysholm scale score (55.3±25.4). SF-36 provided the following scores: physical functioning (41±27.4), physical role functioning (34.6±39.2), bodily pain (45.7±23.6), general health perceptions (63.1±26.2), vitality (53.5±12.1), social role functioning (52.6±29.3), emotional role functioning (41±44.9), mental health (55±27.7). Obesity led to significant loss of physical capacity, gait impairment, knee-related symptoms, and a negative impact on the overall quality of life.

    To determine the feasibility of using social media to perform cross-sectional epidemiologic and quality-of-life research on patients with rare gynecologic tumors, we performed a survey of patients with neuroendocrine tumors of the cervix using Facebook. After approval from our Institutional Review Board, a support group of patients with neuroendocrine tumors of the cervix was identified on Facebook. Group members were asked to complete a survey comprising 84 questions evaluating clinical presentation; treatment; recurrence; quality of life; and sexual function. The survey was posted for 30 days, during which 57 women responded from 8 countries across 4 continents treated at 51 centers. All respondents provided a detailed clinical and tumor history. The mean age was 38.5 years. The stage distribution was stage I, 36 patients (63%); II, 13 (23%); III, 2 (4%); and IV, 6 (11%). Forty-nine patients (86%) had small cell and 8 (14%) had large cell tumors. Forty-five of the respondents (79%) had completed primary therapy and were without evidence of disease. Five (9%) had recurrence, 3 (5%) had persistent disease after therapy, and 4 (7%) were still under treatment. Forty-one patients (72%) reported symptoms at time of presentation. Thirty-seven patients (65%) received multimodality primary therapy. Quality of life instruments demonstrated high scores for anxiety and a negative impact of anxiety and cancer on functional and emotional well-being. Sexual function scores did not differ significantly between respondents and the PROMIS reference population. Use of a social media network to perform epidemiologic and quality of life research on patients with rare gynecologic tumors is feasible and permits such research to be conducted efficiently and rapidly. © 2013.

    The purpose of the present study was to examine self-perceived stress of health professions students at the Faculty of Medicine Foča, and to explore its association with anxiety, depression and health-related quality of life. The cross-sectional study enrolled 451 students at the Faculty of Medicine (medicine, dentistry, nursing and speech therapy). Survey instruments were distributed at the conclusion of the spring semester during the last required lecture for each year and study programme class. Perceived stress was assessed using the 14-item Perceived Stress Scale. The students were evaluated for symptoms of depression and anxiety, using Zung's self-assessment inventory for depression and the Spielberger State-Trait Anxiety Inventory (STAI). European Quality of Life-5 dimensions were used for describing and evaluating health. Multivariate analyses were carried out using logistic regression to examine the relationship between the outcome variable and selected determinant factors. A high degree of stress was reported by 1.6% of students, while the majority of students had either moderate (70.6%) or low degree (27.5%) of stress. The significant independent factors associated with perceived stress were anxiety score (OR, 0.339; CI 95%, 0.276-0.403) and EQ-5D score (OR, 0.044; CI 95%, 0.033-0.085). A high degree of perceived stress (OR, 0.624; CI 95%, 0.507-0.704), the presence of depression (OR, 0.800; CI 95%, 0.513-1.087), and low quality of life were associated with anxiety (OR, 0.073; CI 95%, 0.018-0.128). Higher levels of perceived stress predispose health professions students for anxiety and lower quality of life. The study programme was not a significant determinant of perceived stress sore.

    Assessing the need for prosthodontic care previously included older age groups. There is less information about younger populations who may need this care because of high disease levels. The aim of this study was to assess the normative need for prosthodontic care in a young Saudi population with high oral disease levels, the associated factors and its impact on daily life. A cross sectional study included Saudi adults in the Eastern Province in 2016. A questionnaire was used to assess personal background (confounders), risk factors affecting oral diseases (exposures) and the impact of oral problems on daily life. A clinical examination assessed tooth loss, the presence of prosthodontic appliances, the presence of untreated decay and need for periodontal care. Directed acyclic graphs identified the confounders to be included in regression models with separate outcomes: normative need for prosthodontic care (binary logistic model) and impact on 6 daily life aspects (ordinal regression models). Complete data were available for 574/ 700 = 82% and 46.7% needed prosthodontic care with 2 lost teeth on average among adults of mean age = 33.2 years. The confounders controlled for the need for prosthodontic care included socioeconomic status (SES), dental visits last year and health insurance. The confounders for the impact on daily life included age and SES. In adjusted models, normative need for prosthodontic care was significantly associated with untreated decay (OR = 2.09, 95% C.I. = 1.37, 3.19). The impact on daily life was not significantly associated with prosthodontic care need but with untreated decay, especially sleeplessness (regression coefficient = 0.53, 95% C.I. = 0.02, 1.04) and dropping daily activities (regression coefficient = 0.79, 95% C.I. = 0.13, 1.46). In addition, the need for periodontal care was associated with food avoidance (regression coefficient = 0.73, 95% C.I. = 0.28, 1.18). In Saudi adults in the Eastern Province, there

    Haemodialysis in Malawi consumes a disproportionate amount of the national health budget, costing approximately $20,000 per patient per year. Adjunctive therapeutic agents for end stage kidney disease and laboratory services to measure standard dialysis outcomes are not routinely available. Therefore, alternative outcome measures of the efficacy of haemodialysis in Malawi are required. We measured health related quality of life of adult patients in Malawi treated with haemodialysis for end stage kidney disease. We performed a cross-sectional study of patients receiving haemodialysis for end stage kidney disease at 4 dialysis centres in Malawi between 24/10/2012 and 30/11/012. Patients were included if they were >18 years of age and had been receiving haemodialysis for >3 months. We used the Kidney Disease Quality of Life Instrument Short Form to assess health related quality of life. We recruited 22 of 24 eligible patients (mean age 44.8 ± 16.0 years, 59.1 % male, median duration on haemodialysis 12 months (Inter-quartile range 6-24 months)). Overall health related quality of life was low (mean score 59.9 ± 8.8, maximum possible score 100) with the lowest scores recorded for physical health component summary score (50.4 ± 22.8) compared to mental health component summary (61.3 ± 23.0) and kidney disease component summary (67.9 ± 13.2). Low household income (<$4000 per year) was associated with lower mental health component scores (adjusted r(2) = 0.413, p = 0.033). Quality of life of haemodialysis patients in Malawi can be easily measured using a validated questionnaire and provides an alternative and important measure of the efficacy of haemodialysis therapy. Physical health scores were particularly low and this may affect income generating capacity. Increased efforts are required to improve the quality of life of haemodialysis patients in Malawi with a particular focus on the burden of physical symptoms.

    This study surveys the quality of life of amyotrophic lateral sclerosis patients and the factors associated with amyotrophic lateral sclerosis patients' self-perceived burden and their caregivers' burden. Burdens of patients with amyotrophic lateral sclerosis and their caregivers in Chinese population are largely unknown. A cross-sectional study was conducted among 81 pairs of amyotrophic lateral sclerosis patients and their caregivers. Amyotrophic lateral sclerosis patients' self-perceived burden and caregivers' burden were assessed by the Self-Perceived Burden Scale and Zarit-Burden Interview, respectively. Quality of life of amyotrophic lateral sclerosis patients was measured using the World Health Organization Quality of Life-Bref. The amyotrophic lateral sclerosis Functional Rating Scale-Revised questionnaire was used to estimate patients' physical function. Both patients and caregivers reported a mild to moderate burden. The World Health Organization quality of life-Bref scores were decreased in respondents with lower amyotrophic lateral sclerosis Functional Rating Scale-Revised, higher Self-Perceived Burden Scale and higher Zarit-Burden Interview scores. Self-Perceived Burden Scale scores were associated with patients' knowledge of amyotrophic lateral sclerosis, respiratory function and female sex. Zarit-Burden Interview scores were associated with caregivers' age, patients' motor function and out-of-pocket payment. With increase in amyotrophic lateral sclerosis patients' self-perceived burden and caregivers' burden, quality of life of amyotrophic lateral sclerosis patients decreased. Female patients, who had known more about the disease, and those with severe respiratory dysfunction were subject to higher self-perceived burden. Older caregivers and caregivers of patients with severe motor dysfunction and more out-of-pocket payment experienced more care burdens. Our study suggests that paying more attention to female amyotrophic lateral sclerosis patients

    Many countries are introducing smaller, more home-like care facilities that represent a radically new approach to nursing home care for people with dementia. The green care farm is a new type of nursing home developed in the Netherlands. The goal of this study was to compare quality of care, quality of life and related outcomes in green care farms, regular small-scale living facilities and traditional nursing homes for people with dementia. A cross-sectional design was used. Three types of nursing homes were included: (1) green care farms; (2) regular small-scale living facilities; (3) traditional nursing homes. All participating nursing homes were non-profit, collectively funded nursing homes in the south of the Netherlands. One hundred and fifteen residents with a formal diagnosis of dementia were included in the study. Data on quality of care was gathered and consisted of outcome indicators (e.g. falling incidents, pressure ulcers), structure indicators (e.g. hours per resident per day), and process indicators (e.g. presence, accessibility and content of protocols on care delivery). Furthermore, questionnaires on cognition, dependence in activities of daily living, quality of life, social engagement, neuropsychiatric symptoms, agitation, and depression were used. Data showed that quality of care was comparable across settings. No large differences were found on clinical outcome measures, hours per resident per day, or process indicators. Higher quality of life scores were reported for residents of green care farms in comparison with residents of traditional nursing homes. They scored significantly higher on the Quality of Life - Alzheimer's disease Scale (p quality of life. In addition, residents of green care farms scored higher on three quality of life domains of the Qualidem: positive affect, social relations and having something to do (p  0.7). No differences with regular small-scale living facilities were found. Green care farms seem to be a valuable

    The ESRF non-evaporable getter (NEG) coating facility is in operation since two years now. A large part of the insertion device straight sections of the electron storage ring has been equipped with in-house coated 5m long aluminum vacuum chambers with an inner vertical aperture of 8 mm. Operational experience with different coating parameters leading to different film thicknesses will be given and compared to bremsstrahlung data. The paper deals also with improvements of the coating production and chamber preparation, and describes some aspects of NEG coating data acquisition, visualization, and remote control. The R&D program leading to a more powerful DC solenoidal coating tool to further improve the NEG coating production throughput and quality aspects is also discussed.

    A hydroxyapatite coated femoral stem, matching a retrieved recovered from a case of third body wear, was analysed to investigate particle release from the hydroxyapatite coating. The stem was sectioned into 12 pieces, mounted in epoxy resin and polished to reveal the microstructure. One section was analysed with X-ray diffraction and Fourier transform infra-red spectroscopy. It was found that the coating contained a large amorphous phase content indicating that the coating has the potential for rapid dissolution. The small crystalline particles in the coating were mainly in the 1-8 micron size range. Exposure to dilute nitric acid showed that the coating is capable of releasing particles into the peri-implant area. (orig.)

    ZnO/C hierarchical porous nanorods were synthesized through one-pot wet-chemical reaction followed by thermal calcination. It was found that ZnO/C porous nanorods are composed of numerous nanograins, exhibiting a hierarchical micro/nanostructure. In-situ synchrotron high energy X-ray diffraction study revealed that ZnO/C hierarchical porous nanorods involve a two-step reversible lithiation mechanism during charge/discharge; and part of ZnO and Zn remains at the end of the first discharge and charge process, respectively, leading to a low coulombic efficiency in the initial few cycles. The electrochemical test demonstrated that the reversible capacity and the rate performance of ZnO/C hierarchical porous nanorods anode have been greatly improved by PEDOT-PSS coating, which could maintain a reversible capacity of 623.94 mA h g(-1) after 1500 cycles at 1 C. Its excellent high rate capability and long cycle stability were attributed to the high electronic conductivity of PEDOT-PSS coating layer and the hierarchical structures of ZnO/C porous nanorods.

    Thermal barrier coatings offer an attractive approach to improving the durability and efficiency of the hot section of heat engines. The coatings typically consist of an inner alloy bond coating about 0.01 cm thick resistant to oxidation and hot corrosion and an outer ceramic layer, usually a stabilized zirconia, 0.01-0.05 cm thick. Here, the materials, thermomechanical stress, and hot corrosion problems associated with thermal barrier coatings are reviewed along with the capabilities and limitations of current technology. The coatings discussed include ZrO2-Y2O3/NiCrAlY, ZrO2-Y2O3/NiCoCrAlY, ZrO2-MgO/NiCoCrAlY, CaO-SiO2/Co-Cr-Al-Y, and CaO-SiO2/NiCrAlY systems. It is emphasized that the performance of thermal barrier coatings is governed by many complex and interrelated factors, so that optimization of these coatings always involves certain tradeoffs. 27 references

    A cyclic furnace study was conducted on thermal barrier systems to evaluate the effects of yttrium, chromium and aluminum in nickel-base alloy bond coatings and the effect of bond coating thickness on yttria-stabilized zirconia thermal barrier coating life. Without yttrium in the bond coatings, the zirconia coatings failed very rapidly. Increasing chromium and aluminum in the Ni-Cr-Al-Y bond coatings increased total coating life. This effect was not as great as that due to yttrium. Increased bond coat thickness was also found to increase life.

The objective of this study was to investigate the QoL and self-stigma in connection with demographic factors and compare the two groups of patients in terms of those variables. Methods: In a cross-sectional study, the outpatients with schizophrenia spectrum disorders and depressive disorders completed the Quality of Life Satisfaction and Enjoyment Questionnaire, the Internalized Stigma of Mental Illness Scale, and a demographic questionnaire during a routine psychiatric control. Furthermore, both patients and their psychiatrists evaluated the severity of the disorder by Clinical Global Impression-Severity scale. Results: The QoL of patients with depressive disorders or schizophrenia spectrum disorders did not significantly differ between the two groups. In both groups, unemployment was perceived to be a significant factor decreasing the QoL. Self-stigma was detected to be higher in patients with schizophrenia spectrum disorders than in patients with depressive disorders. A strong correlation was found between the two scales, meaning that those with higher levels of self-stigmatization were less prone to see their life as fulfilling and joyful. Conclusion: This study shows that the degree of the internalized stigma can be an

    Full Text Available Abstract Background To our knowledge, the available psychometric literature does not include an instrument for the quantification of social quality of life among older women from diverse ethnic backgrounds. To address the need for a tool of this kind, we conducted two studies to assess the initial reliability and validity of a new instrument. The latter was created specifically to quantify the contribution of a social networks and resources (e.g., family, friends, and community as well as b one's perceived power and respect within family and community to subjective well-being in non-clinical, ethnically diverse populations of older women. Methods In Study 1, we recruited a cross-sectional sample of primarily non-European-American older women (N = 220 at a variety of community locations. Participants were administered the following: a short screener for dementia; a demographic list; an initial pool of 50 items from which the final items of the new Older Women's Social Quality of Life Inventory (OWSQLI were to be chosen (based on a statistical criterion to apply to the factor analysis findings; the Single Item Measure of Social Support (SIMSS; and the Medical Outcome Study 36-item Short-Form Health Survey (MOS SF-36. Study 2 was conducted on a second independent sample of ethnically diverse older women. The same recruitment strategies, procedures, and instruments as those of Study 1 were utilized in Study 2, whose sample was comprised of 241 older women with mostly non-European-American ethnic status. Results In Study 1, exploratory factor analysis of the OWSQLI obtained robust findings: the total variance explained by one single factor with the final selection of 22 items was over 44%. The OWSQLI demonstrated strong internal consistency (α = .92, p r = .33; p r = .21; p r = .26; p α = .92, p r = .27, p r = .14; p r = .18; p Conclusions The findings of these two studies highlight the potential for our new tool to provide a valid measure of older

    To determine the role played by law in medical specialists' decision-making about withholding and withdrawing life-sustaining treatment from adults who lack capacity, and the extent to which legal knowledge affects whether law is followed. Cross-sectional postal survey of medical specialists. The two largest Australian states by population. 649 medical specialists from seven specialties most likely to be involved in end-of-life decision-making in the acute setting. Compliance with law and the impact of legal knowledge on compliance. 649 medical specialists (of 2104 potential participants) completed the survey (response rate 31%). Responses to a hypothetical scenario found a potential low rate of legal compliance, 32% (95% CI 28% to 36%). Knowledge of the law and legal compliance were associated: within compliers, 86% (95% CI 83% to 91%) had specific knowledge of the relevant aspect of the law, compared with 60% (95% CI 55% to 65%) within non-compliers. However, the reasons medical specialists gave for making decisions did not vary according to legal knowledge. Medical specialists prioritise patient-related clinical factors over law when confronted with a scenario where legal compliance is inconsistent with what they believe is clinically indicated. Although legally knowledgeable specialists were more likely to comply with the law, compliance in the scenario was not motivated by an intention to follow law. Ethical considerations (which are different from, but often align with, law) are suggested as a more important influence in clinical decision-making. More education and training of doctors is needed to demonstrate the role, relevance and utility of law in end-of-life care. Published by the BMJ Publishing Group Limited.

    Occurrence of chronic physical pain is increasingly identified among youth, and medically unsupervised analgesic use is a possible risk factor for opioid dependence and other mental diseases in later life. Therefore, the present study was carried out in young student population in Sikkim, India, to explore predictors (including current chronic pain and current analgesic use) of low QoL in youth to identify a subset of population vulnerable to substance use and mental diseases in later life. The study was conducted in a health university setting in Sikkim, North East India. In this cross-sectional study, 156 participants were enrolled with almost equal number of males and females. Generic instruments for demographics and current analgesic use and SF - 36, for assessment of quality of life (QoL), were used. QoL was measured in general, physical and emotional domains. Presence of chronic physical pain during past four weeks was captured using SF - 36. Almost two-third participants reported presence of current physical pain (69%, n=108); and (14%, n=22) reported current analgesic use for pain. In logistic regression model controlled for age, ethnicity, gender and residence, higher body mass index (BMI) (β=-0.16, P=0.02) and current analgesic use (β=1.6, P=0.006) predicted low QoL in emotional domain (less accomplishment due to emotional problem). Current analgesic use also predicted low QoL in another measure of emotional domain (depressed β=2.0, P=0.001). This study identified a subset of participants in their youth with low QoL in emotional domain predicted by current analgesic use and possible overweight problem. Low QoL in more than one emotional domain also identifies possibility of later psychiatric impairment. However, chronic pain did not emerge as a significant predictor of low QoL in emotional domain.

    Increasing temperatures in aero gas turbines is resulting in oxidation and hot corrosion attack of turbine disks. Since disks are sensitive to low cycle fatigue (LCF), any environmental attack, and especially hot corrosion pitting, can potentially seriously degrade the life of the disk. Application of metallic coatings are one means of protecting disk alloys from this environmental attack. However, simply the presence of a metallic coating, even without environmental exposure, can degrade the LCF life of a disk alloy. Therefore, coatings must be designed which are not only resistant to oxidation and corrosion attack, but must not significantly degrade the LCF life of the alloy. Three different Ni-Cr coating compositions (29, 35.5, 45wt. Cr) were applied at two thicknesses by Plasma Enhanced Magnetron Sputtering (PEMS) to two similar Ni-based disk alloys. One coating also received a thin ZrO2 overcoat. The coated samples were also given a short oxidation exposure in a low PO2 environment to encourage chromia scale formation. Without further environmental exposure, the LCF life of the coated samples, evaluated at 760C, was less than that of uncoated samples. Hence, application of the coating alone degraded the LCF life of the disk alloy. Since shot peening is commonly employed to improve LCF life, the effect of shot peening the coated and uncoated surface was also evaluated. For all cases, shot peening improved the LCF life of the coated samples. Coated and uncoated samples were shot peened and given environmental exposures consisting of 500 hrs of oxidation followed by 50 hrs of hot corrosion, both at 760C). The high-Cr coating showed the best LCF life after the environmental exposures. Results of the LCF testing and post-test characterization of the various coatings will be presented and future research directions discussed.

    Full Text Available Abstract Background In Singapore, the prevalence of end-stage renal disease (ESRD and the number of people on dialysis is increasing. The impact of ESRD on patient quality of life has been recognized as an important outcome measure. The Kidney Disease Quality Of Life-Short Form (KDQOL-SF™ has been validated and is widely used as a measure of quality of life in dialysis patients in many countries, but not in Singapore. We aimed to determine the reliability and validity of the KDQOL-SF™ for haemodialysis patients in Singapore. Methods From December 2006 through January 2007, this cross-sectional study gathered data on patients ≥21 years old, who were undergoing haemodialysis at National Kidney Foundation in Singapore. We used exploratory factor analysis to determine construct validity of the eight KDQOL-SF™ sub-scales, Cronbach's alpha coefficient to determine internal consistency reliability, correlation of the overall health rating with kidney disease-targeted scales to confirm validity, and correlation of the eight sub-scales with age, income and education to determine convergent and divergent validity. Results Of 1980 haemodialysis patients, 1180 (59% completed the KDQOL-SF™. Full information was available for 980 participants, with a mean age of 56 years. The sample was representative of the total dialysis population in Singapore, except Indian ethnicity that was over-represented. The instrument designers' proposed eight sub-scales were confirmed, which together accounted for 68.4% of the variance. All sub-scales had a Cronbach's α above the recommended minimum value of 0.7 to indicate good reliability (range: 0.72 to 0.95, except for Social function (0.66. Correlation of items within subscales was higher than correlation of items outside subscales in 90% of the cases. The overall health rating positively correlated with kidney disease-targeted scales, confirming validity. General health subscales were found to have significant

Specific coping strategies may be connected to both the QoL and the severity of mental disorder. The aim of this investigation was to examine the relationship between the QoL and the coping strategies of outpatients with a depressive disorder.Methods: Eighty-two outpatients, who met the criteria of the International Classification of Diseases, Tenth Revision, for a depressive disorder, were enrolled in the cross-sectional study. Data on sociodemographic and clinical variables were obtained from the medical records. Individuals filled the following standardized questionnaires: Quality of Life Satisfaction and Enjoyment Questionnaire, Stress Coping Style Questionnaire, and Clinical Global Impression. Multiple regression analyses with backward elimination were performed to discover the most influential factors contributing to QoL.Results: The participants with a depressive disorder showed an overuse of negative coping strategies, especially escape tendency and resignation. A positive self-instruction strategy was used by the patients less often. The coping strategies were significantly associated with the QoL. A more frequent use of positive coping strategies had a positive association with the QoL. The main factors related to QoL were the subjective severity of the disorder, employment, and positive coping strategies

    Kidney transplantation is believed to improve health-related quality of life (HRQoL) of patients requiring renal replacement therapy (RRT). Recent studies suggested that the observed difference in HRQoL between kidney transplant recipients (Tx) vs patients treated with dialysis may reflect differences in patient characteristics. We tested if Tx patients have better HRQoL compared to waitlisted (WL) patients treated with dialysis after extensive adjustment for covariables. Eight hundred and eighty-eight prevalent Tx patients followed at a single outpatient transplant clinic and 187 WL patients treated with maintenance dialysis in nine dialysis centres were enrolled in this observational cross-sectional study. Data about socio-demographic and clinical parameters, self-reported depressive symptoms and the most frequent sleep disorders assessed by self-reported questionnaires were collected at enrollment. HRQoL was assessed by the Kidney Disease Quality of Life Questionnaire. Patient characteristics were similar in the Tx vs WL groups: the proportion of males (58 vs 60%), mean ± SD age (49 ± 13 vs 49 ± 12) and proportion of diabetics (17 vs 18%), respectively, were all similar. Tx patients had significantly better HRQoL scores compared to the WL group both in generic (Physical function, General health perceptions, Energy/fatigue, Emotional well-being) and in kidney disease-specific domains (Symptoms/problems, Effect- and Burden of kidney disease and Sleep). In multivariate regression models adjusting for clinical and socio-demographic characteristics, sleep disorders and depressive symptoms, the modality of RRT (WL vs Tx) remained independently associated with three (General health perceptions, Effect- and Burden of kidney disease) out of the eight HRQoL dimensions analysed. Kidney Tx recipients have significantly better HRQoL compared to WL dialysis patients in some, but not all, dimensions of quality of life after accounting for differences in patient

    A complex B-C-N diffusion coating was produced at 580 °C for 1 h on AISI M35 steel substrate and compared with a reference coating formed at 880 °C for 2.5 h. The surface and the cross-sections of the samples were subjected to detailed characterisation. The surface roughness, hardness, residual stresses and adhesion of the coatings were also evaluated together with cutting tests using drills on coated and uncoated samples while monitoring cutting force and torque. The surface of the steel treated at 580 °C revealed Fe2B, boron nitride and boron iron carbide, but FeB was noted to be absent. The 580 °C coating had the fine-scale microstructure, which resulted in the excellent adhesion and enhanced wear resistance, relative to reference samples that contained coarse borides. The results established that a complex fine-scale diffusion coating enhanced the wear resistance and reduces the cutting force and torque during drilling, thereby increasing the drill life by a factor of 2.2.

    Full Text Available In order to improve the tribological properties of an engine piston ring and enhance its service life, magnetron sputtering technology and low temperature ion sulphurizing treatment technology were used to prepare CrMoN/MoS2 solid lubricant coating on the surface of an engine piston ring. The morphologies and compositions of the surface and cross-section of the sulfuration layer were analyzed by field emission scanning electron microscopy (FESEM, and wear property under high load, high speed and high temperature conditions were tested by a SRV®4 friction and wear testing machine. The results show that the CrMoN/MoS2 composite coatings appear as a dense grain structure, and the coating is an ideal solid lubrication layer that possesses an excellent high temperature wear resistance, reducing the engine operating temperature abrasion effectively and prolonging the service life of the engine.

    The operation of the SPS with high intensity bunched beams is limited by the electron cloud building-up in both the arcs and long straight sections. Two consolidation options have been considered: suppression of the electron cloud build-up using coatings or relying, as before, on the scrubbing mitigation. A status report on both options will be given with a particular emphasis on measurements plans for 2012 and pending issues. The testing needs, corresponding beam parameters and MD time in 2012 will be addressed. The criteria for the decision making and the corresponding schedule will be discussed. (author)

    The paper considers the concept of a multi-layer architecture of the coating in which each layer has a predetermined functionality. Latest generation of coatings with multi-layered architecture for cutting tools secure a dual nature of the coating, in which coatings should not only improve the mechanical and physical characteristics of the cutting tool material, but also reduce the thermo-mechanical effect on the cutting tool determining wear intensity. Here are presented the results of the development of combined methods of forming multi-layer coatings with improved properties. Combined method of forming coatings using a pulsed laser allowed reducing excessively high levels of compressive residual stress and increasing micro hardness of the multilayered coatings. The results in testing coated HSS tools showed that the use of additional pulse of laser processing increases tool life up to 3 times. Using filtered cathodic vacuum arc deposition for the generation of multilayer coatings based on TiAlN compound has increased the wear-resistance of carbide tools by 2 fold compared with tool life of cutting tool with commercial TiN coatings. The aim of this study was to develop an innovative methodological approach to the deposition of multilayer coatings for cutting tools with functional architectural selection, properties and parameters of the coating based on sound knowledge of coating failure in machining process.

This oligomer is produced by reacting an epoxy-containing vinyl monomer with alpha-, beta-ethylene unsaturated carboxylic acids or their anhydrides. The composition (I) contains 10% - 100% of this oligomer. In embodiments, an oligomer having a fiberous trivinyl construction is produced by reacting 180 parts by weight of glycidyl methacrylate ester with 130 parts of itaconic acid in the presence of a polymerization-inhibitor and an addition reaction catalyst at 90 0 C for 6 hours. In practice, the coating material compositions (1), consist of the whole oligomer [I-1]; (2), consist of 10-90% of (A) component and 90%-10% of vinyl monomers containing at least 30% (meth) acrylic monomer [I-2]; (3), 10%-90% of component (A) and 90%-10% of other monomers containing at least two vinyl radicals [I-3]; (4), a mixture of (I-2) and (I-3), [I-4]; and (5), consist of 50% or less unsaturated polyester of 500-5,000 molecular weight range or drying oil, or alkyd resin of 500-5,000 molecular weight range modified by drying oil, [I-5]. As a catalyst a tertiary amino vinyl compound is preferred. Five examples are given. (Iwakiri, K.)

    Rotavirus is the leading cause of severe diarrhea in young children and infants worldwide, representing a heavy public health burden. Limited information is available regarding the impact of rotavirus gastroenteritis on the quality of life of affected children and their families. The objectives of study were to estimate the impact of rotavirus infection on health-related quality of life (HRQL), to assess the social and emotional effects on the families of affected children. This study enrolled all (n = 527) RotaStrip®-positive (with further PCR detection) cases (0-18 years of age) hospitalized from April 2013 to December 2015 and their caregivers. A questionnaire comprising clinical (filled-in by the medical staff) and social (filled by the caregivers) sections was completed per child. Main indicators of emotional burden reported by caregivers were compassion (reported as severe/very severe by 91.1% of parents), worry (85.2%), stress/anxiety (68.0%). Regarding social burden, 79.3% of caregivers reported the need to introduce changes into their daily routine due to rotavirus infection of their child. Regarding economic burden, 55.1% of parents needed to take days off work because of their child's sickness, and 76.1% of parents reported additional expenditures in the family's budget. Objective measures of their child's health status were not associated with HRQL of the family, as were the parent's subjective evaluation of their child's health and some sociodemographic factors. Parents were significantly more worried if their child was tearful (p = 0.006) or irritable (p emotional, social or economic burden, whereas the parents' subjective perception of the child's health status and sociodemographic characteristics, were influential. A better understanding of how acute episodes affect the child and family, will help to ease parental fears and advise parents on the characteristics of rotavirus infection and the optimal care of an infected child.

    Full Text Available Abstract Background Information on the health-related quality of life (HRQoL of patients with genital warts (GW in populations in mainland China is still limited. The aim of the study was to use a generic instrument to measure the impact of genital warts on HRQoL in men and women in this setting. Methods A multi-centre hospital-based cross-sectional study across 18 centers in China was conducted to interview patients using the European quality of life-5 dimension (EQ-5D instrument; respondents' demographic and clinical data were also collected. Results A total of 1,358 GW patients (612 men, 746 women were included in the analysis, with a mean age of 32.0 ± 10.6 years. 56.4% of the patients reported some problems in the dimension of Anxiety/Depression (highest, followed by Pain/Discomfort (24.7% and Mobility (3.5%. The overall visual analogue scale (VAS score of the study population was found to be 65.2 ± 22.0, and the EQ-5D index score was found to be 0.843 ± 0.129 using Japanese preference weights (the Chinese preference was unavailable yet. Patients with lower VAS means and EQ-5D index scores were more often female, living in urban area, and suffering multiple GW (all p values 0.05. Conclusions The HRQoL of patients with GW was substantially lower, compared to a national representative general population in China (VAS = ~80; the findings of different subgroups are informative for future GW prevention and control efforts.

Self-stigma is a maladaptive psychosocial phenomenon disturbing the QoL in a substantial number of psychiatric patients. In our study, we examined the relationship between demographic data, the severity of symptoms, self-stigma, and QoL in patients with schizophrenia spectrum disorder.Methods: Probands who met International Classification of Diseases-10 criteria for schizophrenia spectrum disorder (schizophrenia, schizoaffective disorder, or delusional disorder were recruited in the study. We studied the correlations between the QoL measured by the QoL Satisfaction and Enjoyment Questionnaire, self-stigma assessed by the Internalized Stigma of Mental Illness, and severity of the disorder measured by the objective and subjective Clinical Global Impression severity scales in this cross-sectional study.Results: A total of 109 psychotic patients and 91 healthy controls participated in the study. Compared with the control group, there was a lower QoL and a higher score of self-stigmatization in psychotic patients. We found the correlation between an overall rating of self-stigmatization, duration of disorder, and QoL. The level of self-stigmatization correlated positively with total symptom severity score and negatively with the QoL. Multiple regression analysis revealed that the overall rating of objective symptom severity and the score of self-stigma were significantly associated with the QoL.Conclusion: Our study suggests a negative impact of self-stigma level on the QoL in patients suffering from schizophrenia spectrum disorders.

    We examine the characteristics of participants entering Norwegian Healthy Life Centres, their reasons for attending and whether socio-economic status, motivation, self-efficacy and social support relate to physical activity and sedentary behaviour. This cross-sectional study is part of a randomised controlled trial. Inclusion criteria are that participants should be ≥ 18 years old and able to take part in a physical activity group intervention. Exclusion criteria are severe mental illness and general learning disability. We analysed data using simple and multiple linear regression analyses. We recruited 118 participants from eight Norwegian municipalities between June 2014 and September 2015. Of these, 77% were female, mean (standard deviation) age 48.6 (13.4) years, body mass index 34.0 (5.8) kg/m 2 and mean gross family income €61,000. The proportion of participants with upper-secondary school or less as their highest level of education was 55%. The most frequent reasons given for attendance at Healthy Life Centres were being overweight, increasing physical activity, improving diet and having musculoskeletal health challenges. Participants had high levels of autonomous motivation and 79% achieved national recommendations for physical activity. Respect and appreciation in childhood, self-esteem and self-rated health were associated with self-efficacy and social support for physical activity. Participants were predominantly obese, physically active, female and motivated for change. A high proportion had low educational attainment and low incomes. The trial will reveal whether interventions succeed in increasing physical activity further, or in decreasing sedentary behaviour, and whether health inequalities narrow or widen across groups.

    The distribution and severity of dental caries among preschool children vary according to the socio-economic and ethnic differences within and between countries. Understanding socio-economic influences on child oral health could inform early interventions to reduce the oral health burden throughout the life-cycle. The aim of this study is to examine the socio-economic and ethnic influences on oral health among preschoolers in Kegalle, Sri Lanka. The study involved 784 children aged between 48-72 months recruited from 84 pre-schools in the Kegalle district in Sri Lanka. Cross-sectional data were collected by means of an oral examination of the children and a self-administered questionnaire to their parents/caregivers. The Early Childhood Oral Health Impact Scale (ECOHIS) was used to assess Oral Health related Quality of Life (OHQoL). Univariate and multivariate models of Poisson regression were used to investigate the associations between the variables. Compared to children whose fathers had tertiary education, those whose fathers did not study beyond grade 5, had more caries measured in terms of decayed, missing and filled surfaces (dmfs) (IRR = 2.30; 95% CI: 1.30, 4.06; p poor OHQoL at child (IRR = 2.52; 95% CI: 1.20, 5.31; p gingival bleeding (bleeding surfaces) (IRR = 3.04; 95% CI: 1.92, 4.81; p poor OHQoL at child level (IRR = 2.07; 95% CI: 1.19, 3.60; p poor OHQoL at family level (IRR = 1.42; 95% CI: 1.10, 1.84; p oral health outcomes exist among this population of preschoolers. Interventions targeting children of fathers with low educational levels and ethnic minority groups are required to reduce inequalities in oral health in Sri Lanka and other similar countries.

    Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than 'generalized' Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (M age  = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

    Psoriasis is a common, chronic inflammatory immunologically mediated disease of the skin, showing a high prevalence of associated comorbidities, and strongly affecting patients' health-related quality of life (HR-QOL), with profound impact on the psychological aspect. We aimed to establish the correlation between HR-QOL and the associated comorbidities in patients with moderate to severe psoriasis in Spain. A cross-sectional, observational, epidemiological study was conducted at 68 dermatology-based centers across Spain. From October 2010 to June 2011, all adult patients diagnosed with moderate to severe psoriasis at least 6 months prior to the study visit and receiving or not receiving treatment for psoriasis were eligible for inclusion. A total of 1022 patients were included. The study population showed mean 36-item short-form (SF-36) physical and mental health scores and Dermatological Life Quality Index (DLQI) of 49.7, 46.2 and 5.3, respectively. The multiple linear regression models showed that patients with moderate to severe psoriasis and a diagnosis of psoriatic arthritis (PsA), hypertension, diabetes mellitus, sleep disturbances or obesity were found to have lower SF-36 health physical scores. Female patients with depression or anxiety disorders had lower SF-36 health mental scores. Patients diagnosed with moderate to severe psoriatic disease and associated anxiety disorder had greater DLQI scores. Moderate to severe psoriasis has a significant burden on the HR-QOL of patients. Regardless of sex, patients with several comorbidities such as PsA, hypertension or obesity were found to have worse scores in the physical component of the QOL questionnaire, whilst women were more affected in the mental health component than men. © 2014 Japanese Dermatological Association.

    This questionnaire-based cross-sectional study was conducted (1) to estimate the prevalence of sleep-related problems, and (2) to explore factors associated with lower physical/mental quality of life (QOL), particularly addressing sleep-related problems among Japanese visually impaired people. This nationwide questionnaire-based survey was administered to visually impaired individuals through the Japan Federation of the Blind. Visually impaired individuals without light perception (LP) (n = 311), those with LP (n = 287), and age-matched and gender-matched controls (n = 615) were eligible for this study. Study questionnaires elicited demographic information, and information about visual impairment status, sleep-related problems, and health-related quality of life. Visually impaired individuals with and without LP showed higher prevalence rates of irregular sleep-wake patterns and difficulty maintaining sleep than controls (34.7% and 29.4% vs. 15.8%, 60.1% and 46.7% vs. 26.8%, respectively; p sleep-related problems were observed more frequently in visually impaired individuals without LP than in those with LP. Non-restorative sleep or excessive daytime sleepiness was associated with lower mental/physical QOL in visually impaired individuals with LP and in control subjects. However, visually impaired individuals without LP showed irregular sleep-wake pattern or difficulty waking up at the desired time, which was associated with lower mental/physical QOL. Sleep-related problems were observed more frequently in visually impaired individuals than in controls. Moreover, the rates of difficulties were higher among subjects without LP. Sleep-related problems, especially circadian rhythm-related ones, can be associated with lower mental/physical QOL in visually impaired individuals without LP. © 2016 American Academy of Sleep Medicine

    Full Text Available BACKGROUND: Cognitive impairment occurs in about 50% of multiple sclerosis (MS patients, and the use of self-reported outcomes for evaluating treatment and managing care among subjects with cognitive dysfunction has been questioned. The aim of this study was to provide new evidence about the suitability of self-reported outcomes for use in this specific population by exploring the internal structure, reliability and external validity of a specific quality of life (QoL instrument, the Multiple Sclerosis International Quality of Life questionnaire (MusiQoL. METHODS: DESIGN: cross-sectional study. INCLUSION CRITERIA: MS patients of any disease subtype. DATA COLLECTION: sociodemographic (age, gender, marital status, education level, and occupational activity and clinical data (MS subtype, Expanded Disability Status Scale, disease duration; QoL (MusiQoL and SF36; and neuropsychological performance (Stroop color-word test. STATISTICAL ANALYSIS: confirmatory factor analysis, item-dimension correlations, Cronbach's alpha coefficients, Rasch statistics, relationships between MusiQoL dimensions and other parameters. PRINCIPAL FINDINGS: One hundred and twenty-four consecutive patients were enrolled. QoL scores did not differ between the 69 cognitively non-impaired patients and the 55 cognitively impaired patients, except for the symptoms dimension. The confirmatory factor analysis performed among the impaired subjects showed that the structure of the questionnaire matched with the initial structure of the MusiQoL. The unidimensionality of the MusiQoL dimensions was preserved, and the internal validity indices were satisfactory and close to those of the reference population. CONCLUSIONS/SIGNIFICANCE: Our study suggests that executive dysfunction did not compromise the reliability and the validity of the self-reported QoL questionnaires.

  18. Cold-Sprayed AZ91D Coating and SiC/AZ91D Composite Coatings

    Full Text Available As an emerging coating building technique, cold spraying has many advantages to elaborate Mg alloy workpieces. In this study, AZ91D coatings and AZ91D-based composite coatings were deposited using cold spraying. Coatings were prepared using different gas temperatures to obtain the available main gas temperature. Compressed air was used as the accelerating gas, and although magnesium alloy is oxidation-sensitive, AZ91D coatings with good performance were obtained. The results show that dense coatings can be fabricated until the gas temperature is higher than 500 °C. The deposition efficiency increases greatly with the gas temperature, but it is lower than 10% for all coating specimens. To analyze the effects of compressed air on AZ91D powder particles and the effects of gas temperature on coatings, the phase composition, porosity, cross-sectional microstructure, and microhardness of coatings were characterized. X-ray diffraction and oxygen content analysis clarified that no phase transformation or oxidation occurred on AZ91D powder particles during cold spraying processes with compressed air. The porosity of AZ91D coatings remained between 3.6% and 3.9%. Impact melting was found on deformed AZ91D particles when the gas temperature increased to 550 °C. As-sprayed coatings exhibit much higher microhardness than as-casted bulk magnesium, demonstrating the dense structure of cold-sprayed coatings. To study the effects of ceramic particles on cold-sprayed AZ91D coatings, 15 vol % SiC powder particles were added into the feedstock powder. Lower SiC content in the coating than in the feedstock powder means that the deposition efficiency of the SiC powder particles is lower than the deposition efficiency of AZ91D particles. The addition of SiC particles reduces the porosity and increases the microhardness of cold-sprayed AZ91D coatings. The corrosion behavior of AZ91D coating and SiC reinforced AZ91D composite coating were examined. The Si

    The mechanical integrity of resorbable implants during service, especially in load bearing orthopaedic applications, is critical. The high degradation rate of resorbable magnesium and magnesium-based implants in body fluid may potentially cause premature in-service failure. In this study, a magnesium alloy (AZ91) was potentiostatically coated with hydroxyapatite at different cathodic voltages in an attempt to enhance the mechanical integrity. The mechanical integrity of the uncoated and hydroxyapatite coated alloys was evaluated after in vitro testing of the coated samples in simulated body fluid (SBF). The uncoated alloy showed 40% loss in the mechanical strength after five days exposure to SBF. However, the hydroxyapatite coated alloy exposed to SBF showed 20% improvement in the mechanical strength as compared to that of the uncoated alloy. The alloy coated potentiostatically at -2 V performed better than the -3 V coated alloy. The cross-sectional analysis of the coatings revealed relatively uniform coating thickness for the -2 V coated alloy, whereas the -3 V coated alloy exhibited areas of uneven coating. This can be attributed to the increase in hydrogen evolution on the alloy during -3 V coating as compared to -2 V coating. The scanning electron micrographs of the in vitro tested alloy revealed that hydroxyapatite coating significantly reduced the localized corrosion of the alloy, which is critical for better in-service mechanical integrity. Thus, the study suggests that the in vitro mechanical integrity of resorbable magnesium-based alloy can be improved by potentiostatic hydroxyapatite coating. © 2011 IOP Publishing Ltd

    Worldwide, disaster exposure and consequences are rising. Disaster risk in New Zealand is amplified by island geography, isolation, and ubiquitous natural hazards. Wellington, the capital city, has vital needs for evacuation preparedness and resilience to the devastating impacts and increasing uncertainties of earthquake and tsunami disasters. While poor quality of life (QoL) is widely-associated with low levels of engagement in many health-protective behaviors, the relationships among health-related quality of life (HrQoL), well-being, and preparedness are virtually unknown. We hypothesized that QoL and well-being affect household evacuation preparedness. We performed a quantitative epidemiologic survey (cross-sectional design) of Wellington adults. Our investigation assessed health-promoting attributes that build resiliency, conceptualized as health-protective attitudes and behaviors. Multidimensional QoL variables were measured using validated psychometric scales and analyzed for associations with evacuation preparedness, and we determined whether age and gender affected these relationships. We received 695 survey responses (28.5% response rate; margin of error ±3.8%; 80% statistical power to detect true correlations of 0.11 or greater). Correlational analyses showed statistically significant positive associations with evacuation preparedness for spiritual well-being, emotional well-being, and life satisfaction. No associations were found for mental health, social well-being, or gender; physical health was weakly negatively associated. Evacuation preparedness increased with age. Regression analyses showed that overall health and well-being explained 4.6-6.8% of the variance in evacuation preparedness. Spiritual well-being was the only QoL variable that significantly and uniquely explained variance in preparedness. How well-being influences preparedness is complex and deeply personal. The data indicate that multidimensional readiness is essential, and

    Purpose This study aimed to determine the prevalence and severity of recurrent wheezing (RW) defined as ≥3 episodes of wheezing, risk factors, and treatments prescribed during the first year of life in Latin American infants. Methods In this international, cross-sectional, and community-based study, parents of 12,405 infants from 11 centers in 6 South American countries (Argentina, Brazil, Chile, Colombia, Peru, and Uruguay) completed a questionnaire about wheezing and associated risk/protective factors, asthma medications, and the frequency of and indications for the prescription of antibiotics and paracetamol during the first year of life. Results The prevalence of RW was 16.6% (95% CI 16.0-17.3); of the 12,405 infants, 72.7% (95% CI 70.7-74.6) visited the Emergency Department for wheezing, and 29.7% (27.7-31.7) was admitted. Regarding treatment, 49.1% of RW infants received inhaled corticosteroids, 55.7% oral corticosteroids, 26.3% antileukotrienes, 22.9% antibiotics ≥4 times mainly for common colds, wheezing, and pharyngitis, and 57.5% paracetamol ≥4 times. Tobacco smoking during pregnancy, household income per month <1,000 USD, history of parental asthma, male gender, and nursery school attendance were significant risk factors for higher prevalence and severity of RW, whereas breast-feeding for at least 3 months was a significant protective factor. Pneumonia and admissions for pneumonia were significantly higher in infants with RW as compared to the whole sample (3.5-fold and 3.7-fold, respectively). Conclusions RW affects 1.6 out of 10 infants during the first year of life, with a high prevalence of severe episodes, frequent visits to the Emergency Department, and frequent admissions for wheezing. Besides the elevated prescription of asthma medications, there is an excessive use of antibiotics and paracetamol in infants with RW and also in the whole sample, which is mainly related to common colds.

    . For a neutron guide the cost of shielding around the guide is a substantial part of the total cost of the guide. We are therefore looking at other materials than Ni for m=1 coatings. Both Be and diamond have the same or higher neutron scattering density than Ni, and have a much smaller absorption cross section....... Because of the lower absorption cross section, and because of fewer emitted gamma ray photons when a neutron is absorbed, these coatings are producing much less gamma radiation and therefore reduce the shielding costs. Be is frequently used in a wide range of science and technology applications. The only...... chemical hazard after manufacture is Be dust if the sample is destroyed. We have a sample of 276 nm Be coated on a Si wafer for these tests. Diamond Like Carbon (DLC) coatings with 99% sp3 bindings (meaning it is very close to diamond) are made commercially using CVD techniques. In the coating...

    This study presents an evaluation of the environmental performance of an ice cream cup made of polyethylene (PE)/paper laminate using a life cycle assessment approach 'from cradle to grave'. Two opposite alternative disposal scenarios, as well as their intermediate combinations, were considered: 100% incineration and 100% landfilling. The environmental impacts were calculated using the EPD 2013 evaluation method since the study was developed in an Environmental Product Declaration perspective as well as the method ReCiPe 2008 H at the endpoint level. PE/paper laminate production was the most impactful process since it provided the highest contribution to total impacts in four of six impact categories considered. Ice cream cup production was the second impactful process. The 100% incineration scenario provided negligible contribution to life cycle total impact for all impact categories; while considering the landfilling scenario, the percentage contributions to the total impact provided by the end-of-life phase increased considerably, until to be comparable to the contributions provided by the production processes of the PE/paper laminate and the ice cream cup. The obtained results highlighted that different disposal scenarios can affect significantly the conclusions of a study. At the endpoint level, incineration was more environmentally sound than landfilling for all the ReCiPe damage categories.

    Compassion fatigue is a problem for many health care providers manifesting as physical, mental, and spiritual exhaustion. Our objective was to evaluate the association between prior combat deployment and compassion fatigue among military emergency medicine providers. We conducted a nonexperimental cross-sectional survey of health care providers assigned to the San Antonio Military Medical Center, Department of Emergency Medicine. We used the Professional Quality of Life Scale V survey instrument that evaluates provider burnout, secondary traumatic stress, and compassion satisfaction. Outcomes included burnout, secondary traumatic stress, and compassion satisfaction raw scores. Scores were compared between providers based on previous combat deployments using two-tailed independent sample t tests and multiple regression models. Surveys were completed by 105 respondents: 42 nurses (20 previously deployed), 30 technicians (11 previously deployed), and 33 physicians (16 previously deployed).

    Full Text Available Hypertension is a major risk factor of cardiovascular disease in China, and yet little is known about health-related quality of life (HRQOL and its associations with demographic and social-economic characteristics in middle-aged patients with hypertension. A cross-sectional survey was undertaken in Chongqing, China, using a multistage stratified random sampling methodology. Data was collected on 1,224 eligible adults, aged between 45 and 53 years, including the Medical Outcomes Survey Short Form-36 to measure HRQOL. Hypertension was associated with poor state of physical functioning, role-physical, bodily pain, general health, vitality, and social function (p<0.05 for all. In multivariable analyses, education level, job conditions, average monthly income, smoking status, sleep quality, perception of relationship with family, childhood breastfeeding history, and body mass index were associated with domains of SF36 among those with hypertension (p<0.05 for all. Hypertensive respondents with high education, marital status, breastfeeding, higher incomes, good quality of sleep, positive relationship with family, and higher body mass index have better HRQOL in middle-aged people with hypertension. Those unemployed had a better state of general health and had a poorer state of social function. Nonsmokers had a poorer state of bodily pain than smokers. This study provides detailed information of the implications for health care providers to gain a more complete picture of their hypertension patients’ health.

    The effects of two modalities of dose-escalated radiotherapy on health-related quality of life (HRQOL) were compared. Forty-one consecutive patients were treated with a 3-D conformal (3-DC) boost to 74 Gy, and 43 with high-dose rate (HDR) brachytherapy boost (2x9 Gy), following 3-D conformal treatment to 46 Gy. Median age was 70 years in both groups, median initial PSA was 7.9 μg/l in 3-DC boost patients and 8.1 μg/l in HDR boost patients. Stage was 7 in 52% and 47%, respectively. HRQOL was assessed cross-sectionally using EORTC QLQ-C30 and organ-specific PR25 modules 3-32 (median 19) and 4-25 (median 14) months after treatment, respectively. Questionnaires were completed by 93% and 97% of patients, respectively. Diarrhea and insomnia scores were significantly increased in both groups. In the PR25 module, scores of 3-DC boost and HDR boost patients for urinary, bowel and treatment-related symptoms were similar. Among responders, 34% of 3-DC boost patients and 86% of HDR boost patients had severe erectile problems. Dose escalation in prostate cancer by either 3-DC boost to 74 Gy or HDR brachytherapy boost appears to result in similar HRQOL profiles

    Full Text Available This is a post hoc analysis of quality of life in diabetic neuropathy patients in a cross-sectional survey performed in 2012 in Romania, using the Norfolk QOL-DN in which 21,756 patients with self-reported diabetes were enrolled. This current analysis aims to expand research on the diabetic foot and to provide an update on the number of foot ulcers found in Romania. Of the 21,174 patients included in this analysis, 14.85% reported a history of foot ulcers and 3.60% reported an amputation. The percentage of neuropathy patients with foot ulcers increased with age; the lowest percentage was observed in the 20–29-year age group (6.62% and the highest in the 80–89-year age group (17.68%. The highest number of amputations was reported in the 70–79-year age group (largest group. Compared to patients without foot ulcers, those with foot ulcers had significantly higher scores for total DN and all its subdomains translating to worse QOL (p<0.001. This analysis showed a high rate of foot ulcers and amputations in Romanian diabetic patients. It underscores the need for implementation of effective screening and educational programs.

    Social outcomes and quality of life (QOL) of childhood cancer survivors (CCSs) remain unknown in Japan. We investigated these outcomes in young adult CCSs compared to those of their siblings in Japan, and analyzed the association between social outcome and SF-36 health survey subscale scores. Between 2007 and 2009, we performed a cross-sectional survey using self-rating questionnaires. We estimated social outcomes and health-related QOL by performing the SF-36 in each group: CCSs with or without stem cell transplantation (SCT)/radiotherapy (RT) and their siblings. Adjusted odds ratios for outcomes of interest were estimated using logistic regression analysis. Questionnaires from 185 CCSs and 72 CCS's siblings were analyzed. There were no differences in educational attainment or annual income. The SF-36 subscale scores of CCSs with SCT and RT were significantly lower than those of siblings in physical functioning (PF) (p < 0.001 and 0.003, respectively) and general health (GH) (both p = 0.001). Lower PF scores correlated with recurrence (p = 0.041) and late effects (p = 0.010), and poor GH scores with late effects (p = 0.006). The CCSs had made efforts to attain educational/vocational goals; however, a significant proportion of CCSs who had experienced late effects remain at increased risk of experiencing diminished QOL.

    Shared-housing arrangements (SHA) are a German type of small-scale living arrangements for people with dementia (PwD). The involvement of family members is one core domain of SHA. But it has not been investigated yet, what are factors associated with family visits and if family involvement within SHA contributes to better residents' quality of life (QoL). A cross-sectional study including all SHA in Berlin/Germany was performed. Main parameters of interest were residents' QoL (QUALIDEM) and frequencies of family visits within the SHA. Besides descriptive analyses we used logistic regression and ANCOVA to analyze the data. 58 SHA with 396 residents (78.4 years, 69.4% female) participated in the study. Older (OR: 1.034; 95% CI: 1.005; 1.064) and female residents (OR: 2.006; 95% CI: 1.018; 3.950) got more often visited by family members. An active participation of family members in SHA contributes on average to a better QoL in terms of social relationship and social isolation (all ANCOVA p family visits compared to those without family members. The involvement of family members in SHA is common but on a similar level compared to other care arrangements. Staff should convince available family members to visit PwD, in order to improve residents QoL. However, the response rate in the present study was about 13%, which may limit the results.

    Full Text Available Background: Cerebral palsy (CP is group of disorders characterized by long-term disabilities that affect the quality of life (QoL of both patients and those caring for them. Objective: The objective of this study was to measure the QoL of CP patients and their caregivers and determine the factors affecting both of them. Methods: This was a cross-sectional facility-based study. 65 caregivers of children with CP aged 4–18 years completed a self-structured questionnaire. Descriptives of the samples were displayed, and logistic regression was used in the analysis. Results: The scores of overall QoL of both children and caregivers were low, however, variations were observed among different domains. Both health-related and sociodemographic factors were found to affect the QoL of children and caregivers. The increase in the degree of disability and presence of complications decreased the children QoL while the availability of health insurance improved it. Whereas the QoL of the caregiver was affected by his/her occupation, the degree of child disability did not affect it. Conclusions: This study showed that many feasible changes can be adopted to improve the QoL of CP patients and their caregivers.

    Owing to its remarkable electrical and mechanical properties, graphene has been attracting tremendous interest in materials science. In particular, its chemical stability and impermeability make it a promising protective membrane. However, recent investigations reveal that single layer graphene...... cannot be used as a barrier in the long run, due to galvanic corrosion phenomena arising when oxygen or water penetrate through graphene cracks or domain boundaries. Here, we overcome this issue by using a multilayered (ML) graphene coating. Our lab- as well as industrial-scale tests demonstrate that ML...... graphene can effectively protect Ni in harsh environments, even after long term exposure. This is made possible by the presence of a high number of graphene layers, which can efficiently mask the cracks and domain boundaries defects found in individual layers of graphene. Our findings thus show...

    A non-solvent type coating material composition is provided which can be hardened by irradiation with active energy, particularly electron beams, using a composition which contains 10%-100% of a radically polymerizable low molecular compound (A), (hereafter called an oligomer), having at least two vinyl radicals in one molecule. These compositions have a high degree of polymerization and characteristics equivalent to thermosetting acrylic or amino alkyd resin. The oligomer (A) is produced by reacting an epoxy-containing vinyl monomer with saturated polycarboxylic acids or anhydrides. In one embodiment, 146 parts by weight of adipic acid and 280 parts of glycidyl methacrylate ester undergo addition reaction in the presence of a polymerization-inhibitor and a catalyst at 90 0 C for 6 hours to produce an oligomer having a fiberous divinyl construction. The coating composition utilizes this oligomer in the forms of (I-1), a whole oligomer; (I-2), 0%-90% of this oligomer and 90%-10% of a vinyl monomer containing at least 30% of (meth) acrylic monomer; (I-3), 10%-90% of such oligomer and 90%-10% of other monomers containing at least two vinyl radicals in one molecule; (I-4), a mixture of (I-2) and (I-3) in proportion of 1/9 to 9/1, and (I-5), above four compositions each containing 50% or less unsaturated polyester or drying oil having 500-5,000 molecules or a drying oil-modified alkyd resin having 500-5,000 molecules. Four examples are given. (Iwakiri, K.)

    In search of new electrode materials for lithium-ion batteries, metal phosphides that exhibit desirable properties such as high theoretical capacity, moderate discharge plateau, and relatively low polarization recently have attracted a great deal of attention as anode materials. However, the large volume changes and thus resulting collapse of electrode structure during long-term cycling are still challenges for metal-phosphide-based anodes. Here we report an electrode design strategy to solve these problems. The key to this strategy is to confine the electroactive nanoparticles into flexible conductive hosts (like carbon materials) and meanwhile maintain a monodispersed nature of the electroactive particles within the hosts. Monodispersed carbon-coated cubic NiP 2 nanoparticles anchored on carbon nanotubes (NiP 2 @C-CNTs) as a proof-of-concept were designed and synthesized. Excellent cyclability (more than 1000 cycles) and capacity retention (high capacities of 816 mAh g -1 after 1200 cycles at 1300 mA g -1 and 654.5 mAh g -1 after 1500 cycles at 5000 mA g -1 ) are characterized, which is among the best performance of the NiP 2 anodes and even most of the phosphide-based anodes reported so far. The impressive performance is attributed to the superior structure stability and the enhanced reaction kinetics incurred by our design. Furthermore, a full cell consisting of a NiP 2 @C-CNTs anode and a LiFePO 4 cathode is investigated. It delivers an average discharge capacity of 827 mAh g -1 based on the mass of the NiP 2 anode and exhibits a capacity retention of 80.7% over 200 cycles, with an average output of ∼2.32 V. As a proof-of-concept, these results demonstrate the effectiveness of our strategy on improving the electrode performance. We believe that this strategy for construction of high-performance anodes can be extended to other phase-transformation-type materials, which suffer a large volume change upon lithium insertion/extraction.

    An electrically conductive protective coating or film is provided over the surface of a reflective coating of a solar mirror by flowing or directing a cation containing liquid and an anion containing liquid onto the conductive surface. The cation and the anion containing liquids are spaced from, and preferably out of contact with one another on the surface of the reflective coating as an electric current is moved through the anion containing liquid, the conductive surface between the liquids and the cation containing liquid to coat the conductive surface with the electrically conductive coating.

    Coatings produced by physical vapor deposition (PVD) enhance the performance of tools for a broad variety of production processes. In addition to TiN, nowadays (Ti,Al)N and Ti(C,N) coated tools are available. This gives the opportunity to compare the performance of different coatings under identical machining conditions and to evaluate causes and phenomena of wear. TiN, (Ti,Al)N and Ti(C,N) coatings on high speed steel (HSS) show different performances in milling and turning of heat treated steel. The thermal and frictional properties of the coating materials affect the structure, the thickness and the flow of the chips, the contact area on the rake face and the tool life. Model tests show the influence of internal cooling and the thermal conductivity of coated HSS inserts. TiN and (Ti,Zr)N PVD coatings on cemented carbides were examined in interrupted turning and in milling of heat treated steel. Experimental results show a significant influence of typical time-temperature cycles of PVD and chemical vapor deposition (CVD) coating processes on the physical data and on the performance of the substrates. PVD coatings increase tool life, especially towards lower cutting speeds into ranges which cannot be applied with CVD coatings. The reason for this is the superior toughness of the PVD coated carbide. The combination of tough, micrograin carbide and PVD coating even enables broaching of case hardened sliding gears at a cutting speed of 66 m min -1 . (orig.)

    Full Text Available Diabetes is accompanied by a marked reduction in patient's quality of life (QOL and leads to higher disability-adjusted life years than most diseases. Depression further deteriorates QOL and is associated with poor treatment outcomes and lowered glycemic control in diabetes. We analysed the QOL and depression among the people living with diabetes in Nepal.We conducted a cross-sectional survey among a random sample of 157 diabetic patients visiting diabetes clinic at a major teaching hospital in Kathmandu, Nepal. We administered the Nepali version of WHO-BREF for face to face interviews to obtain data on QOL scores. The Nepali version of Patient Health Questionnaire-9was also used to record responses on depression items.More than half of the respondents (54.1% experienced depression with mean PHQ-9 score of 6.15 ± 5.01 on a scale of 0-27. On a scale of 0 to 100, highest QOL mean score was reported in social relationship domain (57.32 ± 11.83, followed by environment domain (54.71 ± 7.74, psychological health (53.25 ± 10.32 and physical health (50.74 ± 11.83. After adjusting for other covariates, urban residence decreased the physical health score by 4.74 (β = -4.74, 95% CI: -8.664,-0.821, social relationship domain score by 3.420 (β = -3.420, 95% CI: -6.433,-0.406 and the overall QOL by 2.773 (β = -2.773, 95% CI: -5.295,-0.252. Having diagnosed with diabetes since more than 10 years increased physical health by 5.184 score points (β = 5.184; 95% CI: 0.753, 9.615.Similarly, having severe depression decreased social relation domain score by 6.053 (β = -6.053, 95% CI:-11.169,-.936.Having urban residence significantly decreased the physical health and social relation domain scores as well as the overall QOL scores. Similarly, having diagnosed since more than 10 years increased physical health domain score. Severe depression decreased social relationship domain score. Since depression affects QOL, we suggest early diagnosis and prompt

    Full Text Available Background & Objective:  Patients with severe immuno-suppression are at risk of having poor oral hygiene and severe periodontal diseases, thus limiting their quality of life. The objective of this study was to assess the impact of oral health-related quality of life (OHRQoL in patients with HIV/AIDS and its association with the CD4 cell count.Materials & Methods:  A cross-sectional study was conducted using Oral Health Impact Profile-14 (OHIP-14 among 122 HIV/AIDS patients visiting the CD4 laboratory at a tertiary healthcare center at Dharan, from January-December 2009. Oral examination and recording of dental indices were done. CD4 cell count was correlated with OHIP-14 and dental indices using Spearman’s rho; p < 0.01 was considered as statistically significant.Results:  Sixty four males and 58 females with median age of 34 years had a mean CD4 cell count of 360.46 cells/mm3 (range=111-1076 cells/mm3. OHRQoL was affected in 25.4% of the individuals with mean OHIP-14 score of 2.5. Most of the individuals (85.7% were on ART, never used tobacco (68% or alcohol (74.5%. Mean OHI-S and DMFT were 1.65 and 1.57, respectively and periodontal pocket observed in only 3.3% individuals. The CD4 cell count had no significant positive correlation with OHIP-14 ((rs=0.071; p=0.61, OHI-S (rs=0.21; p=0.127 and DMFT (rs=0.015; p=0.912. There was no significant difference in parameters with regards to gender.Conclusion: Although CD4 cells are an important indicator for clinical aggravation of HIV infection, OHRQoL and oral health as measured by OHI-S, DMFT and CPI are not directly associated to the CD4 cell count.

    Background: Decision-makers have begun to recognize Health-Related Quality of Life (HRQoL) as an important and measurable outcome of healthcare interventions; and HRQoL data is increasingly being used by policy-makers to prioritize health resources. Our objective was to measure HRQoL in a group of Type 2 Diabetes Mellitus (T2DM) patients receiving insulin treatment in Buenos Aires, Argentina. Methods: We conducted a cross-sectional study of patients with T2DM over 21 years of age, treated with either Neutral Protamine Hagedorn (NPH) insulin or Insulin Glargine (IG), who had not changed their baseline schedule in the last 6 months. The recruitment was during 2006–7 in nine private diabetes specialists’ offices in Buenos Aires, Argentina. A standardized diabetes-specific HRQoL questionnaire, the Audit of Diabetes Dependent Quality of Life (ADDQoL), was used. Results: A total of 183 patients were included (93 receiving NPH and 90 receiving IG). The mean QoL score was: 0.98 (SD: 0.89) and the diabetes specific QoL was: -1.49 (SD: 0.90). T2DM had a negative impact on HRQoL with a mean Average Weighted Impact (AWI) score on QoL of -1.77 (SD: 1.58). The greatest negative impact was observed for domains: ‘worries about the future’, ‘freedom to eat’, ‘living conditions’, ‘sex life’, and ‘family life’. The mean AWI score was -1.71 (SD: 1.48) in patients treated with IG and -1.85 (SD: 1.68) in patients receiving NPH, this difference was not statistically significant. Conclusion: The ADDQoL questionnaire is a tool that can be used in Argentina to measure the QoL of patients with diabetes when evaluating diabetes care programs. The scores of QoL in our selected population did not differ from those reported in high-income countries. We expect that the results of this study will increase healthcare providers’ awareness of patients’ perceived QoL and help to overcome the barriers that delay insulin treatment; mainly clinical inertia and patient

    The burden of ulcerative colitis (UC) in relation to disease severity is not well documented. This study quantitatively evaluated the relationship between disease activity and quality of life (QoL), as well as health care utilization, cost, and work-related impairment associated with UC in an Australian population. A cross-sectional, noninterventional, observational study was performed in patients with a wide range of disease severity recruited during routine specialist consultations. Evaluations included the Assessment of Quality of Life-8-dimension (AQoL-8D), EuroQol 5-dimension, 5-level (EQ-5D-5L), the disease-specific Inflammatory Bowel Disease Questionnaire (IBDQ), and the Work Productivity and Activity Impairment (WPAI) instrument. The 3-item Partial Mayo Score was used to assess disease severity. Health care resource utilization was assessed by chart review and patient questionnaires. In 175 patients, mean (SD) AQoL-8D and EQ-5D-5L scores were greater for patients in remission (0.80 [0.19] and 0.81 [0.18], respectively) than for patients with active disease (0.70 [0.20] and 0.72 [0.19], respectively, both Ps<0.001). IBDQ correlated with both AQoL-8D (r=0.73; P<0.0001) and EQ-5D-5L (0.69; P<0.0001). Mean 3-month UC-related health care cost per patient was AUD $2914 (SD=$3447 [mean for patients in remission=$1970; mild disease=$3736; moderate/severe disease=$4162]). Patients in remission had the least work and activity impairment. More severe UC disease was associated with poorer QoL. Substantial health care utilization, costs, and work productivity impairments were found in this sample of patients with UC. Moreover, greater disease activity was associated with greater health care costs and impairment in work productivity and daily activities. Copyright © 2013 European Crohn's and Colitis Organisation.

    Sickle Cell Disease (SCD) is associated with chronic multisystem complications that significantly influence the quality of life (QOL) of patients early in their life. Although sub-Saharan Africa bears 75% of the global burden of SCD, there is a paucity of data on these complications and their effects on the QOL. We aimed to record these chronic complications, to estimate the QOL, and to identify the corresponding risk factors in patients with SCD receiving care in three hospitals in Cameroon. In this cross-sectional study, a questionnaire was used to collect data from consecutive consenting patients. Information recorded included data on the yearly frequency of painful crisis, the types of SCD, and the occurrence of chronic complications. A 36-Item Short Form (SF-36) standard questionnaire that examines the level of physical and mental well-being, was administered to all eligible participants. Data were analyzed with STATA® software. Of 175 participants included, 93 (53.1%) were female and 111 (aged ≥14 years) were eligible for QOL assessment. The median (interquartile range, IQR) age at diagnosis was 4.0 (2.0-8.0) years and the median (IQR) number of yearly painful crisis was 3.0 (1.0-7.0). The most frequent chronic complications reported were: nocturnal enuresis, chronic leg ulcers, osteomyelitis and priapism (30.9%, 24.6%, 19.4%, and 18.3% respectively). The prevalence of stroke and avascular necrosis of the hip were 8.0% and 13.1% respectively. The median (IQR) physical and mental scores were 47.3 (43.9-58.5) and 41.0 (38.8-44.6) respectively. Age and chronic complications such as stroke and avascular necrosis were independently associated with poor QOL. In this population of patients living with SCD, chronic complications are frequent and their QOL is consequently poor. Our results highlight the need for national guidelines for SCD control, which should include new-born screening programs and strategies to prevent chronic complications.

The objective of this paper was to compare general (rather than health-related QOL and affective well-being in middle aged and older people across eight chronic illnesses.This population-based, cross-sectional study involved 11,523 individuals aged 50 years and older, taking part in wave 1 of the English Longitudinal Study of Ageing. General QOL was assessed using the CASP-19, happiness was evaluated using two items drawn from the GHQ-12, and depression was measured with the CES-D. Analysis of covariance and logistic regression, adjusting for age, gender and wealth, were performed. General QOL was most impaired in people with stroke (mean 37.56, CI 36.73-38.39, and least in those reporting cancer (mean 41.78, CI 41.12-42.44, respectively, compared with no illness (mean 44.15, CI 43.92-44.39. Stroke (mean 3.65, CI 3.58-3.73 was also associated with the greatest reduction in positive well-being whereas diabetes (mean 3.81, CI 3.76-3.86 and cancer were least affected (3.85, CI 3.79-3.91, compared with no illness (mean 3.97, CI 3.95-4.00. Depression was significantly elevated in all conditions, but was most common in chronic lung disease (OR 3.04, CI 2.56-3.61, with more modest elevations in those with osteoarthritis (OR 2.08, CI 1.84-2.34 or cancer (OR 2.07, CI 1.69-2.54. Multiple co-morbidities were associated with greater decrements in QOL and affective well-being.The presence of chronic illness is associated with impairments in broader aspects of QOL and affective well-being, but different conditions vary in their impact. Further longitudinal work is needed to establish the temporal links between chronic illness and impairments in QOL and affective well-being.

    Axial Spondyloarthritis (AxSpA) and chronic low back pain are rheumatic diseases that impact patients' health-related quality of life (HRQoL). In other chronic conditions, HRQoL was positively associated with dispositional optimism, a personality trait. The objective was to explore the relationship between optimism and HRQoL in these two diseases. A cross-sectional study was performed in 2 tertiary care hospitals and 2 private practices in France. Patients had definite AxSpA or chronic low back pain according to the rheumatologist. A generic HRQoL questionnaire (Short Form, SF-12) with physical and mental composite scores (PCS and MCS respectively) and an optimism questionnaire (the Life Orientation Test-revised, LOT-R) were collected. Analyses included non-parametric correlations and multiple regression analyses to study the effect of optimism on PCS and MCS. In all, 288 (199 AxSpA and 89 low back pain) patients were included: mean age, 47.3 ± 11.9 years, 48.6 % were males. Pain levels (0-10) were 4.5 ± 2.4 and 4.3 ± 2.4 in AxSpA and LOW BACK PAIN patients, respectively. HRQoL was similarly altered in both diseases, for both physical and mental composite scores (mean PCS: 43.7 ± 8.2 vs. 41.9 ± 7.1; mean 45.9 ± 7.8 vs. 46.7 ± 8.1 for AxSpA and low back pain respectively). Optimism was moderate and similar in both populations. Optimism was positively correlated to MCS in both diseases (rho = 0.54 and 0.58, respectively, both p Optimism was similar in these 2 chronic diseases and was an explanatory factor of the mental component of HRQoL, but not physical HRQoL. Physical HRQoL may reflect more the disease process than character traits.

    College teachers in China are confronted with a lot of pressure from teaching, researching and living. They are suffering from impaired physical and mental health. The purpose of this study was to investigate the relationships between organizational behavior factors and college teachers' health related quality of life (HRQOL), and to confirm whether they are positive resources for improving teachers' HRQOL. A cross-sectional survey was conducted in Shenyang, China, from January to April 2014. Participants were composed of 965 teachers randomly selected from five representative colleges in Shenyang. Self-administrated questionnaires containing the 36-item Short-Form Health Survey (SF-36), the Chinese version Psychological Capital Questionnaire (PCQ), and scales assessing group identification, POS, and psychological empowerment were used to measure HRQOL and organizational behavior variables of college teachers. Hierarchical multiple regression analysis (HMR) was performed to explore the effects of organizational behavior variables on college teachers' HRQOL. The mean (SD) scores of physical component summary (PCS) and mental component summary (MCS) among college teachers were 71.43 (14.70) and 65.46 (16.55) respectively in the study population. Hierarchical multiple regression analysis showed that group identification (β = 0.121, P < 0.001) and PsyCap (β = 0.336, P < 0.001) were significant predictors of PCS, while group identification (β = 0.107, P < 0.001), POS (β = 0.124, P = 0.003), psychological empowerment (β = 0.093, P = 0.017) and PsyCap (β = 0.421, P < 0.001) were significant predictors of MCS. Chinese college teachers experienced relatively low level of HRQOL and their mental quality of life (QOL) were impaired more seriously than physical QOL. Organizational behavior factors (PsyCap, group identification, POS and psychological empowerment) were strong predictors of college teachers' HRQOL and are

    Quality of life (QoL) is an important aspect of wellbeing for people with chronic conditions like type 2 diabetes, making it a noteworthy outcome. Knowledge about diabetes, attitudes, and self-management of diabetes are key factors that might directly or indirectly impact QoL. However, little is known about the inter-relationships between diabetes knowledge, attitudes, self-management and QoL among people with type 2 diabetes mellitus (T2DM). The aim of this study was to examine a model describing the relationship between diabetes knowledge, attitudes, self-management, and QoL of people with T2DM that is based on previous research linking pairs of these variables. A cross-sectional study design was employed in this research. A total of 291 participants, 192 males and 99 females, with T2DM, whose mean age was 55.8 (standard deviation = 11.09) completed questionnaires measuring diabetes knowledge (Diabetes Knowledge Scale), attitudes (Diabetes Integration Scale -19), self-management (Summary of Diabetes Self-care Activities Scale), including the aspects of diet, exercise, blood glucose testing, and foot care, and QoL (Diabetes Quality of Life Scale), comprising the aspects of satisfaction and impact on QoL respectively. To examine the model we proposed relating these variables, data were analysed using the path analysis. In the final model, diabetes knowledge was a significant predictor for attitudes and self-management in terms of blood glucose testing. Attitudes was a significant predictor for self-management in terms of diet. In addition, self-management in terms of blood glucose testing was a significant predictor of impact of QoL, and self-management in terms of diet was a significant predictor of satisfaction and impact of QoL. Self-management in terms of exercise was a significant predictor of satisfaction in QoL. The final model reflected a good fit (χ(2) (14) = 22.52, p = 0.069; CFI = 0.983; GFI = 0.983; RMSEA = 0.046).

    Full Text Available Background Decision-makers have begun to recognize Health-Related Quality of Life (HRQoL as an important and measurable outcome of healthcare interventions; and HRQoL data is increasingly being used by policy-makers to prioritize health resources. Our objective was to measure HRQoL in a group of Type 2 Diabetes Mellitus (T2DM patients receiving insulin treatment in Buenos Aires, Argentina. Methods We conducted a cross-sectional study of patients with T2DM over 21 years of age, treated with either Neutral Protamine Hagedorn (NPH insulin or Insulin Glargine (IG, who had not changed their baseline schedule in the last 6 months. The recruitment was during 2006–7 in nine private diabetes specialists’ offices in Buenos Aires, Argentina. A standardized diabetes-specific HRQoL questionnaire, the Audit of Diabetes Dependent Quality of Life (ADDQoL, was used. Results A total of 183 patients were included (93 receiving NPH and 90 receiving IG. The mean QoL score was: 0.98 (SD: 0.89 and the diabetes specific QoL was: -1.49 (SD: 0.90. T2DM had a negative impact on HRQoL with a mean Average Weighted Impact (AWI score on QoL of -1.77 (SD: 1.58. The greatest negative impact was observed for domains: ‘worries about the future’, ‘freedom to eat’, ‘living conditions’, ‘sex life’, and ‘family life’. The mean AWI score was -1.71 (SD: 1.48 in patients treated with IG and -1.85 (SD: 1.68 in patients receiving NPH, this difference was not statistically significant. Conclusion The ADDQoL questionnaire is a tool that can be used in Argentina to measure the QoL of patients with diabetes when evaluating diabetes care programs. The scores of QoL in our selected population did not differ from those reported in high-income countries. We expect that the results of this study will increase healthcare providers’ awareness of patients’ perceived QoL and help to overcome the barriers that delay insulin treatment; mainly clinical inertia and patient

    In high and upper-middle income countries poly-victimisation (exposure to multiple forms of victimisation) is associated with worse health-related quality of life (HRQoL) among adolescents. There is a lack of empirical evidence about these associations from low- and lower-middle income countries. The aims of this study were to examine the associations between exposure to 1) individual forms of victimisation and 2) poly-victimisation and the HRQoL of adolescents in Vietnam. A cross-sectional, anonymously-completed survey of high school students in Hanoi, Vietnam. Lifetime exposure to eight individual forms of victimisation and poly-victimisation were assessed using the Juvenile Victimisation Questionnaire Revised-2 (JVQ R2). Health-related quality of life was assessed using the Duke Health Profile Adolescent Version (DHP-A). Bi-variate analyses and multiple linear regressions were conducted to assess the associations between individual forms of victimisation, poly-victimisation and HRQoL among girls and boys. In total 1616/1745 students (92.6 %) completed the questionnaire. Adolescent girls had significantly worse HRQoL than boys in all domains, except disability. Different forms of victimisation were associated with different HRQoL domains among girls and boys. Cyber victimisation was the most detrimental to girls' HRQoL while for boys maltreatment was the most detrimental. Experiences of poly-victimisation were associated with worse HRQoL in physical, mental, social and general health, lower levels of self-esteem and increased levels of anxiety, depression and pain domains among both sexes. Among Vietnamese adolescents, experiences of individual forms of victimisation were associated with poorer HRQoL in specific domains; the most detrimental forms of victimisation varied for girls and boys. However, it was experiences of poly-victimisation that had the most detrimental impacts on the HRQoL of both sexes. Recognition of violence, including poly-victimisation, is

    The technical function of numerous engineering systems - such as vehicles, machines, and instruments - depends on the processes of motion and on the surface systems. Many processes in nature and technology depend on the motion and dynamic behavior of solids, liquids, and gases. Smart surface systems are essential because of the recent technological push toward higher speeds, loads, and operating temperatures; longer life; lighter weight and smaller size (including nanotechnology); and harsh environments in mechanical, mechatronic, and biomechanical systems. If proper attention is not given to surface systems, then vehicles, machines, instruments, and other technical systems could have short lives, consume excessive energy, experience breakdowns, result in liabilities, and fail to accomplish their missions. Surface systems strongly affect our national economy and our lifestyles. At the NASA Glenn Research Center, we believe that proper attention to surface systems, especially in education, research, and application, could lead to economic savings of between 1.3 and 1.6 percent of the gross domestic product. Wear coatings and surface systems continue to experience rapid growth as new coating and surface engineering technologies are discovered, more cost-effective coating and surface engineering solutions are developed, and marketers aggressively pursue, uncover, and exploit new applications for engineered surface systems in cutting tools and wear components. Wear coatings and smart surface systems have been used widely in industrial, consumer, automotive, aerospace, and biomedical applications. This presentation expresses the author's views of and insights into smart surface systems in wear coatings. A revolution is taking place in carbon science and technology. Diamond, an allotrope of carbon, joins graphite, fullerenes, and nanotubes as its major pure carbon structures. It has a unique combination of extreme properties: hardness and abrasion resistance; adhesion

    Thermal Barrier Coatings (TBC) are a development of the aerospace industry primarily aimed at hot gas flow paths in turbine engines. TBC consists of zirconia ceramic coatings applied over (M)CrAlY. These coatings can provide three benefits: (1) a reduction of metal surface operating temperatures, (2) a deterrent to hot gas corrosion, and (3) improved thermal efficiencies. TBC brings these same benefits to reciprocal diesel engines but coating longevity must be demonstrated. Diesels require thicker deposits and have challenging geometries for the arc-plasma spray (APS) deposition process. Different approaches to plasma spraying TBC are required for diesels, especially where peripheral edge effects play a major role. Bondcoats and ceramic top coats are modified to provide extended life as determined by burner rig tests, using ferrous and aluminum substrates

    Objectives. We studied the effect of antiretroviral therapy (ART) on the quality of life (QOL) of Cubans with HIV/AIDS. Methods. We conducted a cross-sectional study including administration of the Medical Outcomes Study–HIV Health Survey Questionnaire to a representative sample of the 1592 Cubans receiving ART in 2004. For univariate analyses, we compared mean HIV scale scores. We used logistic regression models to estimate the association between role function and year of diagnosis, between pain and sex, and between health transition and region of diagnosis, with adjustment for demographics, ART regimen, and clinical status. Results. There were 354 participants (73 women, 281 men). Scores for all functional activities showed means higher than 80 out of 100. Pain interfered more in women than in men (73.2 vs 81.9; P = .01). When HIV diagnosis occurred after 2001, the probability of experiencing difficulties performing work (odds ratio [OR] = 4.42; 95% CI = 1.83, 10.73) and pain (OR = 1.70; 95% CI = 1.01, 2.88) increased compared with earlier diagnosis. People treated with indinavir showed a greater perception of general health (58.9 vs 52.4; P = .045) and greater health improvement (78.6 vs 67.8; P = .002). Conclusions. Although Cubans receiving ART are maintaining a high QOL, we observed significant differences by sex and time of diagnosis. QOL assessment can serve as a health outcome and may allow identification of QOL reductions potentially related to ART side effects. PMID:22420793

    Full Text Available Background. Obsessive-compulsive Disorder (OCD is a chronic disabling psychological condition, which can severely affect quality of life (QOL. Growing interest has been dedicated to assessing which domains of QOL are more severely affected in patients with OCD. However, research yielded conflicting findings. Investigating QOL in OCD could suggest the need for integration of interventions aimed at improving those specific domains more severely impaired by obsessions and compulsions.Methods. We will conduct a systematic review of cross-sectional case-control studies according to PRISMA guidelines, where patients with a primary OCD diagnosis were compared on QOL outcomes with healthy controls. Primary objectives will be to examine differences in QOL outcomes between patients with OCD and healthy controls, and to assess which QOL domains are more severely impaired in patients compared with controls, particularly subjective well-being, social and interpersonal functioning, work functioning, and family functioning. Subsequently, the study will investigate potential moderators of QOL in OCD, including participants characteristics (age, sex, presence of comorbid personality disorders, OCD symptom severity, severity of concurrent depressive symptoms, duration of OCD symptoms, and generational cohort, and study characteristics (date of publication and methodological quality of the studies. Online databases will be searched (PsycINFO, PubMED, Science Direct, Cinahl, Biological Abstracts, Psyclit, Embase, The Cochrane Central Register of Controlled Trials, and Google Scholar. To locate unpublished records, conference abstracts, doctoral dissertations and theses will be handsearched, and experts will be contacted. Statistical analyses will be performed though random effect model meta-analysis. Risk of bias assessments will be conducted using the instrument Methodological Index for Non-Randomized Studies.

    Full Text Available Background: Breast cancer is the leading cause of cancer death among women worldwide. In India, the incidence rate of breast cancer is found to be 25.8/10,000 females. The statistics for Kerala, India, is 30.5 in urban areas and 19.8 in rural areas. Cancer and treatment-related symptoms are major stressors in patients with breast cancer undergoing treatment for the disease. Depression is a prevalent psychological symptom perceived by breast cancer patients, and it also impacts the quality of life (QOL in these patients. We aimed to assess the prevalence of depression and its association with QOL of patients with breast cancer undergoing treatment for breast cancer. Materials and Methods: This cross-sectional study enrolled 270 patients diagnosed with breast cancer (>18 years and undergoing active treatment in a tertiary care center in Kerala, India. Depression was assessed using the Patient Health Questionnaire 9 and International Classification of Diseases, Tenth Edition Research guidelines. We measured the QOL and its domains using the WHOQOL-BREF. Results: The average age of women in research was 53.56 years. Of the 270 patients, 21.5% had depression. Among patients with depression, 22% had moderately severe to severe depression. Patients with depression experienced overall a poor QOL. Twenty-two patients reported their overall QOL was “poor” and 34 patients reported to be dissatisfied with their health. There was an association between depression and domains of QOL. Patients with depression had lower scores in all domains when compared to those without depression. Conclusion: Depression and poor QOL is common among breast cancer patients.

Thus, the objective of this study was to investigate the health related quality of life (QoL and the associated socio-demographic determinants among Iranian elderly people. Methods: We conducted a cross-sectional study with a representative samples of 750 elderly people whom community dwelling in urban area of Babol, in the north of Iran. In a household survey, the demographic data were collected and the health related QoL was assessed with a validated standard short form questionnaire (SF-36. The multiple linear regression analysis was performed to determine the demographic characteristics in predicting QoL using SPSS ver 13. Results: The overall mean (SD scores of QoL was 62.4(17.2 for men and 51.2 (17.9 for women. The mean scores of QoL in all dimensions in men had significantly higher than women. The adjusted regression coefficient of gender, age, educational level, being couple were significant on overall scores of QoL. Aging is inversely associated while male gender and education at high school or higher and being couple are positively associated in prediction of overall scores of QoL. Conclusion: The findings indicate that the health related QoL is rather poor in old people particular in women, elderly with low education level and being single. Therefore, healthcare policy makers should consider an urgent health interventional program among elderly people at present stage of demographic transition with emphasis on high risk demographic profiles.

    Full Text Available Introduction: There is an increasing recognition that children's oral health-related quality of life (OHRQoL is affected by social and environmental factors. Aim: To assess the influence of socioeconomic status and home environment factors on OHRQoL among 13–14-year-old schoolchildren in North Bengaluru. Materials and Methods: This cross-sectional study was conducted among 800 children aged 13–14 years from government and private schools in North Bengaluru. OHRQoL was assessed using a shorter version of Child Perceptions Questionnaire (CPQ11-14. Socioeconomic status of children was measured using Kuppuswamy's scale. Children were also asked to provide information on home environmental factors. Descriptive, Chi-square, and Mann–Whitney U-tests were used to analyze data. Results: In both government and private schools, mean CPQ11-14 scores were highest for children belonging to upper lower class followed by the lower middle, upper middle, and upper class of socioeconomic status, showing statistically significant differences (P < 0.05. In government schools, children living with single parent/guardian, having two or more siblings, one or two rooms, staying with more than one person per room, family using alcohol/tobacco reported higher mean CPQ11-14 scores as compared to private schools. (P < 0.05. Conclusion: It is important to shift focus from the current biomedical and restricted paradigm on oral health and develop oral health policies and programs considering the socioeconomic status and home environmental factors in improving child OHRQoL outcomes.

    To measure oral health (OH) knowledge, attitude and practices (KAP) of primary school teachers and to evaluate the relationship between these measures and oral health-related quality of life (OHRQoL). A total of 1013 school teachers from all regions of Kuwait were randomly selected in this cross-sectional study. A questionnaire on demographics, knowledge, attitude, practices and OHRQoL was used. Frequencies and means (SD) were used for data description. Correlations between KAP and OHRQoL were evaluated using Pearson's correlation coefficient. Associations between practice-specific knowledge and its corresponding practice as well as knowledge and practices and OHRQoL were determined using the chi-squared test. About 71% of the participants were females, 57% were 30-50 years old, and 75% had a college education. The mean (95%CI) knowledge score was 60.2% (57.2-62.0), ranging from 15.4% to 93%. The well-known OH facts were the importance of brushing twice a day with fluoridated toothpaste, the cariogenic effect of sticky, sugary foods and snacks, as well as the damage that soft drinks can cause to teeth. The least known facts were replacement frequency of toothbrush, parent's supervision of children's brushing and the benefit of regular flossing. Weak but significant correlations were found between KAP components and OHRQoL (p 0.05). Self-esteem was the mostly frequently affected OHRQoL construct by improper OH practices. Oral health knowledge by itself is not enough to change improper OH practices. Developing behaviourchanging interventions based on OHRQoL outcomes may be beneficial.

    Participation in physical activity (PA) and healthy nutrition are important factors that affects muscle and bone strength and the resultant functioning in the activities of daily living (ADL) skills including the overall quality of life (QoL) of geriatric individuals. However, the relationships between all these parameters are yet to be fully documented and studies from developing countries are lacking. This study was designed to investigate the relationships between PA level, frequency of nutritional intake of food rich in calcium, magnesium, phosphorus, vitamin D and the basic ADL, instrumental ADL and QoL of geriatric individuals in Lagos, Nigeria. A cross-sectional study involving 394 geriatric individuals. A combination of standardized questionnaires which assessed the socio-demographic parameters, PA level, frequency of intake of food rich in calcium, magnesium, phosphorus, vitamin D, ADL skills, and QoL of the geriatric individuals was used. Data was analyzed using descriptive statistics and Pearson's chi-square. The highest proportion (35.5%) of participating geriatric individuals was at the active PA level. PA level was statistically associated with QoL, basic and instrumental ADL, (X2 = 199.57, p = 0.001; X2 = 87.07, p = 0.000; and X2 = 164.53, p = 0.001 respectively). There was also an association between frequency of intake of food rich in calcium, magnesium, phosphorus, vitamin D and the basic ADL (X2 = 97.43, p = 0.001), instrumental ADL (X2 = 151.56, p = 0.001) and QoL (X2 = 250.21, p = 0.001) of the studied geriatric individuals. The study demonstrated that an increase in PA level and regular intake of food rich in calcium, magnesium, phosphorus, vitamin D were associated with optimal functional status and better QoL in geriatric individuals. Educational programmes on the importance of participation in regular PA and healthy nutrition are imperative and recommended for geriatric individuals.

    Because the world population is aging, it has become increasingly important to focus on and meet the healthcare needs of elderly individuals. This study aims to evaluate the relationships among common symptoms experienced by the elderly, including fatigue, pain, sleep disturbance, indigestion, and depression/anger/anxiety, and to assess how these symptoms affect health-related quality of life (HRQoL) in the elderly population after adjusting for sociodemographic characteristics and diagnosed diseases. In a cross-sectional study conducted in 2014 in a rural area of Korea, we extracted data on 1328 elderly individuals aged 60 years or older. Their HRQoL was assessed using the EuroQol Five-Dimension (EQ-5D) questionnaire. The pairwise associations between each symptom and the influence of the symptoms on HRQoL were measured using logistic regression and multiple regression analysis. Each symptom was positively correlated with the other symptoms. The strongest association was observed between fatigue and pain (adjusted odds ratio = 8.127), and the weakest correlation was observed between sleep and indigestion (adjusted odds ratio = 2.521). Of the individuals experiencing symptoms other than sleep disturbance, those who reported comorbid symptoms tended to report higher symptom severity and a higher prevalence of symptoms persisting for ≥ 3 days compared with individuals who reported only one symptom. The number of symptoms was significantly correlated with the EQ-5D index (Spearman correlation coefficient = -0.370, p elderly individuals. Thus, multidisciplinary healthcare programs are required to address these common symptoms.

    Full Text Available Abstract Background Under the culture of filial piety and due to the Confucianism spirit in China, family caregivers usually undertake the responsibilities of caring for the older adults. They usually suffer from a heavy burden which is believed to impair their mental and physical health. Thus this study aims to describe the health-related quality of life (HRQOL among Chinese caregivers of the older adults living in the community and explore the predictors of caregivers’ HRQOL. Methods A cross-sectional study was conducted through convenience sampling. The study population was composed of 1,144 caregivers of older adults who suffered from one or more types of chronic diseases in 15 communities in 3 eastern cities of China. Family caregivers were interviewed face-to-face using the 36-item Short-Form Health Survey (SF-36 and the ZARIT Caregiver Burden interview (ZBI scales. The Antonovsky's Sense of coherence (SOC scale was also used to measure personal coping capability of the caregivers. Hierarchical multiple regression analysis (HMR was performed to explore the predictors of caregivers’ HRQOL. Results The majority of the caregivers were females (60.0% or adult children (66.5%. Mental QOL was significantly lower than physical QOL. Hierarchical multiple regression analysis showed that Demographic Characteristics of Caregivers, Patients’ Characteristics, and Subjective Caregiver Burden explained most of the total variance of all aspects of HRQOL. While, Objective Caregiving Tasks was only associated with physical QOL. Subjective Caregiver Burden was the strongest predictor of both physical and mental QOL. SOC was also a strong predictor of physical and mental QOL. Conclusions The mental QOL of the caregivers of older adults was disrupted more seriously than physical QOL. Additionally, Subjective Caregiver Burden might decrease caregiver’ health. A decrease in caregiver burden could promote better management of caregiving tasks, and improve

    To evaluate associations between anxiety and severe impairment of quality of life (QoL) in Latin American postmenopausal women. This was a secondary analysis of a multicenter cross-sectional study among postmenopausal women aged 40 to 59 from 11 Latin American countries. We evaluated anxiety (The Goldberg Depression and Anxiety Scale), and QoL (Menopause Rating Scale [MRS]), and included sociodemographic, clinical, lifestyle, and anthropometric variables in the analysis. Poisson family generalized linear models with robust standard errors were used to estimate prevalence ratios (PRs) and 95% CIs. There were two adjusted models: a statistical model that included variables associated with the outcomes in bivariate analyses, and an epidemiologic model that included potentially confounding variables from literature review. Data from 3,503 women were included; 61.9% had anxiety (Goldberg). Severe QoL impairment (total MRS score ≥17) was present in 13.7% of women, as well as severe symptoms (MRS subscales): urogenital (25.5%), psychological (18.5%), and somatic (4.5%). Anxiety was independently associated with severe QoL impairment and severe symptoms in the epidemiological (MRS total score: PR 3.6, 95% CI, 2.6-5.0; somatic: 5.1, 95% CI, 2.6-10.1; psychological: 2.8, 95% CI, 2.2-3.6; and urogenital: 1.4, 95% CI, 1.2-1.6) and the statistical model (MRS total score: PR 3.5, 95% CI, 2.6-4.9; somatic: 5.0, 95% CI, 2.5-9.9; psychological: 2.9, 95% CI, 2.2-3.7; and urogenital: 1.4; 95% CI, 1.2-1.6). In this postmenopausal Latin American sample, anxiety was independently associated with severe QoL impairment. Hence, screening for anxiety in this population is important.

    Health-related quality of life (HRQoL) may be worsened in sickle cell patients due to the presence of psychiatric disorders. The aims of this study were to describe the psychiatric symptoms in Brazilian sickle cell patients and to evaluate the relationship of these symptoms to the genotype of the disease and the subject's HRQoL. Cross-sectional study conducted at the hematology outpatient clinic, Hospital São Paulo. Adult patients with sickle cell disease completed the Medical Outcome Study - Short Form 36 and the Patients' Health Questionnaire. Clinical data were gathered from their medical files. Linear regression models were developed to study the dependency of HRQoL domains on the genotype controlling for psychiatric symptoms. In the study period, 110 patients were evaluated. The most frequent psychiatric symptom was depression (30%), followed by anxiety (12.7%) and alcohol abuse (9.1%). Patients with the more severe genotype (SS and Sβthal0) showed lower scores for the "general health" and "role-physical" HRQoL domains, without interference from psychiatric symptoms. In the "role-physical" domain, the more severe genotype operated as a protective factor for HRQoL (β = 0.255; P = 0.007). The more severe genotypes worsened HRQoL in two domains of physical health (general health and role-physical), but they did not have any influence on mental health, thus suggesting that physicians should be more attentive to aspects of HRQoL relating to the functionality of sickle cell disease patients, so as to be aware of the limitations that these patient live with.

    Androgen deficiency is increasingly recognized in young male cancer survivors; however, its impact on quality of life (QOL) is not established. The authors investigated the relationship between androgen levels, QOL, self-esteem, fatigue, and sexual function in young male cancer survivors compared with control subjects. A cross-sectional, observational study of 176 male cancer survivors and 213 male controls aged 25 to 45 years was performed. Subjects completed 3 QOL scales (Medical Outcomes Study 36-Item Short-Form Health Survey version 2, the 12-item General Health Questionnaire [GHQ-12], and Aging Male Scale), and measures of self-esteem (Rosenberg Self-Esteem Scale), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), and sexual function (Derogatis Interview for Sexual Functioning-II Self-Report-Male). Cancer survivors had lower scores for all components of the Short-Form Health Survey, Aging Male Scale, and Functional Assessment of Chronic Illness Therapy-Fatigue, and for 4 of 5 subsections of the Derogatis Interview for Sexual Functioning than controls. The majority of these differences remained after adjusting by linear regression analysis. Levels of psychiatric disorder or self-esteem did not differ between the 2 groups. In cancer survivors, those with androgen deficiency (serum testosterone Sexual Functioning. Serum testosterone only weakly correlated with health measures. Young male cancer survivors self-report a marked impairment in QOL, energy levels, and quality of sexual functioning, and this was exacerbated in those with androgen deficiency. However, psychological distress was not elevated, self-esteem was normal, and sexual relationships were not impaired. The relationship with testosterone is complex, and appears dependent on a threshold level rather than direct correlation. Interventional trials are needed to determine whether testosterone replacement would improve QOL in young male cancer survivors.

    Depression, anxiety, disease severity, and cognitive functions impact on the quality of life of people with MS. However, the majority of studies were not based on multivariate models and did not target employed patients. The aim of this study was to investigate predictors of HRQoL in persons with MS in the workforce considering cognitive, psychological, disease severity, and disability-related variables. Cross-sectional study. Hierarchical block regression analyses were conducted to identify predictors of physical and mental components of HRQoL, measured with the MSQOL-54. Candidate predictors included cognitive functioning (a selection of Rao's BRB-NT), sample features (age, education, MS duration), depressive symptoms (BDI-II), anxiety (STAI-Y), disability (WHODAS 2.0), and MS severity (EDSS): those that correlated with PCS and MCS with p .800 were excluded from regression analyses. In total, 181 patients (60.8% females, mean age 39.6, median EDSS 1.5) were included. In both models, cognitive variables had a poor explicative power. The models improved significantly when psychological, as well as, disease severity and disability variables were added. R(2) of complete models was 0.732 for the physical component, 0.697 for the mental one: BDI-II, STAI-State and, some WHODAS 2.0 scales were significant predictors of HRQoL. Monitoring anxiety, depressive symptoms, and level of disability through self-reported questionnaires may provide useful suggestions to improve the HRQoL of persons with MS in the workforce, permitting to address possible problems in the work context and plan corrective actions.

    Full Text Available Abstract Background The U.S. population is aging and is expected to double by the year 2030. The current study evaluated the prevalence of asthma and its correlates in the elderly Hispanic and non-Hispanic white population. Methods Data from a sample of 3021 Hispanics and non-Hispanic White subjects, 65 years and older, interviewed as part of an ongoing cross-sectional study of the elderly in west Texas, were analyzed. The outcome variable was categorized into: no asthma (reference category, current asthma, and probable asthma. Polytomous logistic regression analysis was used to assess the relationship between the outcome variable and various socio-demographic measures, self-rated health, asthma symptoms, quality of life measures (SF-12, and various occupations. Results The estimated prevalence of current asthma and probable asthma were 6.3% (95%CI: 5.3–7.2 and 9.0% (95%CI: 7.8–10.1 respectively. The majority of subjects with current asthma (Mean SF-12 score 35.8, 95%CI: 34.2–37.4 or probable asthma (35.3, 34.0–36.6 had significantly worse physical health-related quality of life as compared to subjects without asthma (42.6, 42.1–43.1. In multiple logistic regression analyses, women had a 1.64 times greater odds of current asthma (95%CI: 1.12–2.38 as compared to men. Hay fever was a strong predictor of both current and probable asthma. The odds of current asthma were 1.78 times (95%CI: 1.24–2.55 greater among past smokers; whereas the odds of probable asthma were 2.73 times (95%CI: 1.77–4.21 greater among current smokers as compared to non-smokers. Similarly fair/poor self rated health and complaints of severe pain were independently associated with current and probable asthma. The odds of current and probable asthma were almost two fold greater for obesity. When stratified by gender, the odds were significantly greater among females (p-value for interaction term = 0.038.

    Quality of life is associated with several factors, including personal living styles and working conditions. This article aims to investigate the factors associated with quality of life among small and medium enterprises (SME) workers in 4 countries of the Association of Southeast Asian Nations (ASEAN), namely Malaysia, Indonesia, Thailand, and Vietnam. A total of 2014 workers from food and textile industries were asked to answer a questionnaire about their sociodemographic characteristics, working environment and conditions, and quality of life. Results from showed that lifestyle (ie, alcohol intake and exercising), working characteristics (ie, shift work, working hours, and working days) and workplace conditions were associated with SME workers' quality of life (ie, physical, psychological, social, and environmental domain). Among the 16 types of workplace conditions, "sitting on the chair" and "slippery floor" most affect their quality of life . It is important for these variables to be taken into account in promoting workers' well-being and quality of life.

    Fresh-cut cantaloupes have been implicated in numerous foodborne outbreaks of salmonellosis. Commercial aqueous wash treatments are limited in their ability to inactivate Salmonella enterica. Our objective was to evaluate the efficacy of hot water, gaseous chlorine dioxide, and chlorine on enhancing microbial safety and sensory qualities of fresh-cut cantaloupes. Cantaloupes were inoculated with an S. enterica cocktail (serovars Michigan, Mbandaka, and Poona) and treated with chlorine (200 ppm of free chlorine) for 40 min, 5 mg/L gaseous chlorine dioxide for 4.5 h, and hot water (76.1°C) for 3 min. Fresh-cut cantaloupes were prepared from treated whole cantaloupes and divided into two sets; one set of samples was treated with NatureSeal to evaluate its effect on shelf life and sensory quality and the second set (control) was packed without further treatment. Fresh-cut samples were stored at 4°C for up to 21 days. For the sensory quality parameters analyzed (color, water loss, and texture), the samples treated with NatureSeal had significantly better quality ( P < 0.05) than did the control samples. All treatments significantly reduced ( P < 0.05) the pathogen populations on the rind of the whole melons and on the fresh-cut samples prepared from the treated melons. All fresh-cut samples prepared from melons treated with hot water were negative for Salmonella throughout the storage period except for the samples treated with hot water and NatureSeal and evaluated on day 7. The fresh-cut samples prepared from melons treated with chlorine dioxide and chlorine were negative for Salmonella after 21 days of storage. These results provide a framework to producers of fresh-cut cantaloupes for the potential use of hot water as an intervention treatment in combination with NatureSeal for enhancing the microbiological safety and quality of this commodity.

    Full Text Available Abstract Background Suicide is a leading cause of death in Australian males aged 18 to 55. Non-fatal suicidal behaviours and thoughts are indicators of increased risk for future suicide. Suicidal behaviour is complex and multi-determined. Research supports the involvement of stressful life events in suicide and suicidal behaviour, however the evidence regarding suicidal thoughts is less developed. This study investigates stressful life events in relation to suicidal ideation in a large cohort of adult males recruited into Ten to Men, the Australian Longitudinal Study on Male Health. Methods Baseline data from a national cohort of 13, 884 males aged 18–55 years on suicidal behaviour, psychiatric disorder and life events was used. Multivariable logistic regressions were conducted with current suicidal ideation as the outcome and 12 month life events, 12 month depression, anxiety and harmful/hazardous alcohol use, and socio-demographics as covariates. Further logistic regression models investigated the relative risk of life stress alone, depression/alcohol/anxiety alone and co-occurring life stress and depression/alcohol/anxiety. Results In multivariable models there was an independent contribution to suicidal ideation for six of 24 life events (ORs 1.27–1.95, 12 month depression (OR 4.49 harmful alcohol use (OR 1.38 and anxiety disorders (OR 1.27. Life events co-occurring with depression (OR 10.3 was higher risk than either alone (depression OR 6.6; life stress OR 2.6. There was a lesser effect for co-occurrence in the anxiety and harmful alcohol use models. Conclusion Life events appear to be related to suicidal ideation independent of depression, anxiety and harmful alcohol use in adult males, however if life events occur in the context of depression that risk is substantially increased.

    2015-01-01

    Environmental barrier coatings (EBCs) and SiCSiC ceramic matrix composites (CMCs) systems will play a crucial role in next generation turbine engines for hot-section component applications because of their ability to significantly increase engine operating temperatures with improved efficiency, reduce engine weight and cooling requirements. This paper will emphasize advanced environmental barrier coating developments for SiCSiC turbine airfoil components, by using advanced coating compositions and processing, in conjunction with mechanical and environment testing and durability validations. The coating-CMC degradations and durability in the laboratory simulated engine fatigue-creep and complex operating environments are being addressed. The effects of Calcium-Magnesium-Alumino-Silicate (CMAS) from road sand or volcano-ash deposits on the degradation mechanisms of the environmental barrier coating systems will be discussed. The results help understand the advanced EBC-CMC system performance, aiming at the durability improvements of more robust, prime-reliant environmental barrier coatings for successful applications of the component technologies and lifing methodologies.

    There is a lack of data on quality of life in long-term survivors of nasopharyngeal carcinoma (NPC) who have been treated with intensity-modulated radiation therapy (IMRT). We characterized long-term disease-specific and cognitive QoL in NPC survivors after IMRT. We conducted a cross-sectional study of surviving patients diagnosed and treated for NPC at our center with curative-intent IMRT, with or without chemotherapy. Patients who were deceased, still undergoing treatment, with known recurrent disease, or treated with RT modality other than IMRT were excluded. QoL was measured by FACT-NP and FACT-Cog. Between May and November 2013, 44 patients completed cognitive (FACT-Cog), general (FACT-G), and NPC-specific (NPCS) QoL assessments. Patients were categorized into 4 cohorts based on duration since IMRT (≤2.5, >2.5–6, >6–10, and >10–16 years). There was no significant difference in age (p = 0.20) or stage ((I/II vs III/IV: p = 0.78) among the cohorts. The 4 cohorts differed overall for all QoL measures (ANOVA: p < 0.02 for each), due to improved scores >2.5–6 years post-IMRT compared with ≤2.5 years post-IMRT (post hoc tests: p ≤ 0.04 for each). No differences were observed between >2.5–6 and >6–10 years post-IMRT, but lower mean FACT-Cog and NPCS scores were observed for >10 years compared to >2.5–6 years post-IMRT (post hoc: p < 0.05 for each). All QoL measures were low during the initial recovery period (≤2.5 years) and were higher by 6 years post-IMRT. At >10 years post-IMRT, lower scores were observed in the domains of NPC-specific and cognitive QoL. Survivors of NPC, even if treated with IMRT, are at risk for detriment in domain-specific QoL measures at very long-term follow-up

    China has experienced rapid urbanization over the past several decades. Social capital is considered a vital human resource, and quality of life (QoL) is an important measure of human health embedded in a physical, mental, and social context. No studies have reported on the association between social capital and QoL in Chinese urban residents. We performed a cross-sectional study to investigate social capital in urban community residents of West China, and its relationship with QoL.Our study was carried out between June and July of 2015. A total of 1136 households were surveyed. The Chinese-translated version of the Short-Form Health Survey (SF-12) and social capital questionnaire were used to evaluate people's QoL and social capital. Associations between QoL and social capital were evaluated by 3 logistic regression analyses.A total of 1136 adult participants aged 18 years and older completed the questionnaire. Young residents were more likely to have lower second (SC2), third (SC3), and fourth (SC4) dimensions of social capital. Migrants and residents with higher education levels and high incomes showed lower SC1 and SC2 relative to other participants, and employed residents had relatively low SC1. Unmarried residents had lower SC2 and SC3. Without adjustment for potential confounding factors, participants with higher SC2 had higher average scores for mental components (MCS) of QoL [odds ratio (OR) = 1.48, 95% confidence interval (95% CI): 1.09-2.02], and the same was seen for SC3 (OR = 1.70, 95% CI: 1.24-2.34). After adjusting for socioeconomic status (SES) and risk factors, SC2 and SC3 were still significantly associated with MCS. Social capital was not significantly associated with physical components of QoL in any of the 3 logistic regression models.In conclusion, social capital is related to MCS of QoL, and increasing it may be an effective way to promote health.

Adolescents with leprosy-affected parents (n = 102; aged 11–17 years and those with parents unaffected by leprosy (n = 115; 11–17 years were investigated. Self-reported data from adolescents were collected using the Kinder Lebensqualität Fragebogen (KINDLR questionnaire to assess HRQOL, the Center for Epidemiological Studies-Depression Scale (CES-D, and the Rosenberg Self-esteem Scale (RSES. Analysis of covariance (ANCOVA was used to compare scores between the two groups. Multiple regression analysis was conducted to explore the determinants of HRQOL for adolescents with leprosy-affected parents. Results ANCOVA revealed that the KINDLR and RSES scores were significantly lower among adolescents with leprosy-affected parents compared with unaffected parents. However, the scores of “Friends” and “School” subscales of KINDLR were similar between the two groups. The CES-D score was significantly higher among adolescents with leprosy-affected parents than for adolescents with unaffected parents. The KINDLR scores for adolescents with both parents affected (n = 41 were significantly lower than the scores for those with one parent affected (n = 61. Multiple regression analysis revealed that adolescents with leprosy-affected parents who had higher levels of depressive symptoms were more likely to have lower KINDLR scores. A similar result was seen for adolescents where both parents had leprosy. Conclusions Adolescents with leprosy-affected parents had higher levels of depressive symptoms, lower levels of self-esteem, and lower HRQOL compared with adolescents whose

    Wood, Robert J. K.

    2007-09-01

    This paper reviews the available literature relating to the emerging research into the performance of coatings under combined wear and corrosion conditions. Understanding how coatings perform under these tribo-corrosion conditions is essential if the service life of equipment is to be predicted and to allow service life to be extended. Therefore, the tribo-corrosion performance of coatings deposited by a variety of techniques is discussed and the main mechanisms associated with their degradation under combined wear and corrosion highlighted. Coating composition, microstructure, defect level, adhesion, cohesion and substrate properties are seen as some of the critical elements in coating performance when subjected to tribo-corrosion contacts. The importance of post-coating deposition treatments such as laser resurfacing and sealing are also discussed. Interactions between wear and corrosion mechanisms are identified along with some models and mapping techniques that aim to inform coating selection and predict performance. Recent investigations into mono-layer as well as multilayered and functionally graded coatings are reviewed as candidates for wear-corrosion resistant surfaces. The review reveals the need for a more considered approach to tribo-corrosion testing and the way in which the results are analysed and presented. For example, the test conditions should be appropriate to the coating system under test; the level of in situ instrumentation deployed and the post-test analysis of in situ electrochemical data should be carefully selected as well as details given of the composition of any surface tribofilms formed and the identification of the degradation mechanisms.

    Highlights: • Al 2 O 3 -coated concentration-gradient oxide is synthesized by a freeze drying method. • The effect of Al 2 O 3 -coating on concentration-gradient cathode is firstly studied. • Al 2 O 3 -coated sample exhibits high capacity and significantly enhanced cyclability. • Improved cyclability is ascribed to the effective protection of uniform Al 2 O 3 layer. - Abstract: In order to enhance the electrochemical performance of the high capacity layered oxide cathode with a Ni-rich core and a concentration-gradient shell (NRC-CGS), we use a freeze drying method to coat Al 2 O 3 layer onto the surface of NRC-CGS Li[Ni 0.73 Co 0.12 Mn 0.15 ]O 2 material. The samples are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, charge-discharge measurements and electrochemical impedance spectroscopy. It is revealed that an amorphous Al 2 O 3 layer of about 5 nm in thickness is uniformly formed on the surface of NRC-CGS Li[Ni 0.73 Co 0.12 Mn 0.15 ]O 2 material by the freeze drying procedure. The freeze drying Al 2 O 3 -coated (FD-Al 2 O 3 -coated) sample demonstrates similar discharge capacity and significantly enhanced cycling performances, in comparison to the pristine and conventional heating drying Al 2 O 3 -coated (HD-Al 2 O 3 -coated) samples. The capacity decay rate of FD-Al 2 O 3 -coated Li[Ni 0.73 Co 0.12 Mn 0.15 ]O 2 material is 1.7% after 150 cycles at 55 °C, which is 9 and 12 times lower than that of the pristine and HD-Al 2 O 3 -coated samples. The superior electrochemical stability of the FD-Al 2 O 3 -coated sample is attributed to the synergistic protection of CGS and high-quality Al 2 O 3 coating that effectively protect the active material from electrolyte attack. The freeze drying process provides an effective method to prepare the high performance surface-coated electrode materials

    Increasing physical activity in patients with severe mental illness is believed to have positive effects on physical health, psychiatric symptoms and as well quality of life. Till now, little is known about the relationship between physical activity and quality of life in long-term hospitalized patients with severe mental illness and knowledge of the determinants of behavioural change is lacking. The purpose of this study was to elucidate the relationship between objectively measured physical activity and quality of life, and explore modifiable psychological determinants of change in physical activity in long-term hospitalized patients with severe mental illness. In 184 inpatients, physical activity was measured using an accelerometer (ActiGraph GTX+). Quality of life was assessed by EuroQol-5D and WHOQol-Bref. Attitude and perceived self-efficacy towards physical activity were collected using the Physical Activity Enjoyment Scale and the Multidimensional Self Efficacy Questionnaire, respectively. Patient and disease characteristics were derived retrospectively from electronic patient records. Associations and potential predictors were analysed using hierarchical regression. Physical activity was positively related with and a predictor of all quality of life outcomes except on the environmental domain, independent of patient and disease characteristics. However, non-linear relationships showed that most improvement in quality of life lies in the change from sedentary to light activity. Attitude and self-efficacy were not related to physical activity. Physical activity is positively associated with quality of life, especially for patients in the lower spectrum of physical activity. An association between attitude and self-efficacy and physical activity was absent. Therefore, results suggest the need of alternative, more integrated and (peer-)supported interventions to structurally improve physical activity in this inpatient population. Slight changes from sedentary

    The effects of gender, negative life events, and coping on depression have been well-documented. But depression is a heterogeneous syndrome of which the severity ranged from mild depression to major depression. This study aimed to investigate the specific effects of gender, negative life events, and coping on different stages of depression severity. A total of 5989 students (aged 16-25 years, M=20.85, SD=0.58), recruited from six universities in the central region of China using the stratified cluster sampling method, completed Life Events Questionnaire, Coping Response Inventory, and Beck Depression Inventory-Ⅱ. Among the participants, 708 (11.8%) students presented different severity levels of depression. Gender, negative life events, positive coping, and negative coping all had significant effects on depression. That is, the possibility of being depressed was significantly higher in female university students, or students who had more negative life events, more negative coping, or positive coping. In terms of the different stages of depression severity, all these factors had significant effects on the stage from non- depression to mild depression; only gender, negative life events and positive coping had significant effects on the stage from mild depression to moderate depression; only gender had a significant effect on the stage from moderate depression to major depression. The causal role of these factors on different stages of depression severity could not be inferred. Moreover, the participants were from a non-clinical population. The effects of gender, negative life events and coping varied in different stages of depression severity. The effects of life events and coping styles became insignificant with the increasing severity of depression, whereas the effect of gender remained significant. The results could provide guidance for the prevention, intervention, and treatment of depression. Copyright © 2016. Published by Elsevier B.V.

    Chronic pain affects millions of Americans. Treating chronic pain can be difficult because it is a complex condition influenced by genetic makeup and physiological and psychological factors. The experience of major life events has also been found to affect the psychosocial functioning, health, and health behaviors of patients. Whereas the impact of major life events on the use of traditional medical practices has been explored, only one study to date has examined the relationship between major life events and use of complementary and alternative medicine (CAM). This study examined the impact of major life events on the use of CAM among patients with chronic pain syndromes. Participants were consecutive patients seeking treatment at a pain clinic. The study occurred at a tertiary center for pain management in Southern California. Participants were adult patients experiencing chronic pain for at least 6 mo, seeking treatment at a pain center. Participants completed a measure assessing their use of CAM modalities as well as their receptiveness to using previously unused CAM modalities, and they provided demographic information, including the occurrence of major life events, such as a job loss. A total of 199 adults with chronic pain participated in the study. The majority (91.6%) of chronic pain patients in the study reported using at least one form of CAM, with an average of at least five different forms of CAM. Individuals reported receptiveness to CAM modalities that they had not previously used (P CAM use were greater among those that had experienced a major life event in the prior 6 mo (P chronic pain frequently use CAM therapies, especially those who had recently experienced a major life event. Major life events may motivate patients with chronic pain to seek out different forms of CAM as a way to manage their pain.

    The effect of formulated Aloe vera based edible coating on mass loss, colour, firmness, pH, acidity, total soluble solid, ascorbic acid and lycopene on the coated tomato was investigated. The tomato in control showed a rapid deterioration with an estimated shelf life period of 19 days, based on the mass loss, colour changes, accelerated softening and ripening. On the contrary, the coating on tomatoes delayed the ripening and extended the shelf life up to 39 days. The physiological loss in weight was 7.6 and 15.1%, firmness was 36 and 46.2 N on 20th day for control and coated tomatoes, respectively. From the results, it was concluded that the use of Aloe vera based edible coating leads to increased tomato shelf-life.

This study aims to assess the influence of stressful life events and coping skills on risk for suicidal behavior and to elucidate the underlying mechanism using a large sample of university students in China. 5972 students, randomly selected from 6 universities, completed the questionnaire survey. Logistic regression analysis was performed to estimate the effect of stressful life events and coping skills on risk for suicidal behavior. Bayesian network was further adopted to probe their probabilistic relationships. Of the 5972 students, 7.64% reported the presence of suicidal behavior (attempt or ideation) within the past one year period. Stressful life events such as strong conflicts with classmates and a failure in study exam constituted strong risk factors for suicidal behavior. The influence of coping skills varied according to the strategies adapted toward problems with a high score of approach coping skills significantly associated with a reduced risk of suicidal behavior. The Bayesian network indicated that the probability of suicidal behavior associated with specific life events was to a large extent conditional on coping skills. For instance, a stressful experience of having strong conflicts with classmates could result in a probability of suicidal behavior of 21.25% and 15.36% respectively, for female and male students with the score of approach coping skills under the average. Stressful life events and deficient coping skills are strong risk factors for suicidal behavior among youth students. The results underscore the importance of prevention efforts to improve coping skills towards stressful life events.

    Patients with primary Sjögren syndrome (pSS) always suffer from dryness, pain, and fatigue caused by the involvement of multiple different systems or organs. The uncomfortable disease symptoms, the consequent disability, and the side effects of therapeutic drugs decrease the quality of life and lead to emotional problems. We investigated the health-related quality of life and psychological status of a large cohort of women patients with pSS and associated factors.A total of 304 women with pSS referred to Peking Union Medical College Hospital during 2011 and 2014 were included. The internationally recognized Short Form (36) Health Survey (SF-36) was used to assess patients' quality of life; a higher score indicated a better quality of life. Patients' psychological status was assessed by the Hospital Anxiety and Depression Scale (HADS), and higher scores predicted more anxiety or depression.Patients with pSS had remarkably lower SF-36 scores. The Hospital Anxiety Scale (HAS) and Hospital Depression Scale (HDS) scores of the pSS patients (7 [4,10] and 6 [3,10], respectively) were significantly higher than that of patients with other internal diseases (3.37 ± 2.81 and 3.83 ± 3.14; both P quality of life were: pain (physical condition, β = -0.225; P quality of life with anxiety and depression. Pain and fatigue are primary factors for lower quality of life, which cause more anxiety and depression. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

    Little is known about the quality of life of people with very severe dementia in long-term care settings, and more information is needed about the properties of quality of life measures aimed at this group. In this study we explored the profiles of quality of life generated through proxy ratings by care staff and family members using the Quality of Life in Late-stage Dementia (QUALID) scale, examined factors associated with these ratings, and further investigated the psychometric properties of the QUALID. Proxy ratings of quality of life using the QUALID were obtained for 105 residents with very severe dementia, categorised as meeting criteria for Functional Assessment Staging (FAST) stages 6 or 7, from members of care staff (n = 105) and family members (n = 73). A range of resident and staff factors were also assessed. Care staff and family member ratings were similar but were associated with different factors. Care staff ratings were significantly predicted by resident mood and awareness/responsiveness. Family member ratings were significantly predicted by use of antipsychotic medication. Factor analysis of QUALID scores suggested a two-factor solution for both care staff ratings and family member ratings. The findings offer novel evidence about predictors of care staff proxy ratings of quality of life and demonstrate that commonly-assessed resident variables explain little of the variability in family members' proxy ratings. The findings provide further information about the psychometric properties of the QUALID, and support the applicability of the QUALID as a means of examining quality of life in very severe dementia.
