Lubratex eye ointment with polyethylene cover significantly reduces corneal abrasion in ICU patients: a randomized controlled trial

Corneal abrasion is a frequent complication in critically ill, intubated patients, potentially leading to visual impairment. This study compares the efficacy of three ocular care methods in preventing corneal abrasion among this vulnerable population. We conducted a randomized controlled trial involving 156 intubated adult patients admitted to the ICU. Participants were randomly allocated to one of three intervention groups (n = 52 per group): (1) polyethylene cover only, (2) polyethylene cover with artificial tear drops, and (3) polyethylene cover with Lubratex eye ointment. One eye per patient was randomly assigned as the control, receiving standard ICU eye care. Daily assessments over five days included a standardized dryness and corneal abrasion checklist, graded strip evaluation of eye dryness, and documentation of corneal abrasion incidence. Data were analyzed using descriptive and inferential statistics (SPSS-18). The incidence of corneal abrasion was significantly lower in the group receiving polyethylene cover with Lubratex eye ointment (4%) compared to the polyethylene cover with artificial tears group (36%, p < 0.001) and the polyethylene cover only group (60%, p < 0.001). The combined application of a polyethylene cover with Lubratex eye ointment effectively prevents corneal abrasion in intubated ICU patients. This method demonstrates superior efficacy compared to polyethylene covers used alone or with artificial tears. We recommend its implementation as standard practice for corneal abrasion prophylaxis in this high-risk population.Trial Registration.

Agronomic evaluation of iceberg lettuce cultivars in hydroponic system

Lettuce production in hydroponic cultivation has been gradually increasing, but there is great variation with respect to the available technologies, as well as to information on local performance of lettuce cultivars. The objective of this study was to evaluate 11 cultivars of iceberg lettuce in hydroponic system under cultivation under a low-density polyethylene (LDPE) cover, with 150 μm thickness, and in a screenhouse covered with ChoromatiNet®Leno red-pigmented net with 30% shading in the summer in Jataí-GO, Brazil. Two experiments were conducted in a randomized block design with three replicates, one in an environment covered with a red net and the other in a greenhouse covered with transparent plastic. The seedlings were transplanted to the final growth channel 17 days after sowing, and harvest was carried out at 33 days of final growth bench, when the following characteristics were evaluated: head formation, total chlorophyll content, soluble solids content, total fresh mass, marketable fresh mass, stem fresh mass, root fresh mass, number of leaves, stem length and stem diameter. All cultivars showed commercial standard for the fresh market in Jataí-GO.

Maintaining normothermia in newborns and warmed fluids

The most important adaptation of the newborn baby after birth is trying to adapt to the extrauterine environment, which is colder than the intrauterine environment. The World Health Organization; it recommends keeping the axillary body temperature in newborns between 36.5 and 37.5 °C. Attempts to prevent hypothermia and ensure normothermia can be divided into two groups; passive heating and active heating. While the passive heating is maintaining and increasing the ambient temperature, removing wet covers, drying, use of heated towels, hats, clothes and covers, active heating metods can be defined as warmed gel beds, polyethylene cover, warmed gases and warmed liquids.Purpose of warmed intravenous liquids; it is to reduce the contribution of intravenously administered fluids (approximately 25 °C) to hypothermia through convection (heat transfer). There are very limited studies on the use of warmed IV fluids in newborns. Therefore this article is aimed to guide evidence-based studies on different areas including warmed IV liquids, neonatal hypothermia control and neonatal care.

Enzymatic Activities in the Rhizosphere Soil as Influenced by Filterbeds and Hydrophytes in the Vertically Constructed Wetland

An experiment with different filter beds and macrophytes was carried out to study their phytoremediation capacity on the efficiency of domestic wastewater treatment through constructed wetland (CW) at the University of Agricultural Sciences, Dharwad campus, Karnataka, between November 2017 and March 2018. Twenty treatment combinations involving five types of filter beds (FB-1: gravel, FB-2: gravel-sand-gravel, FB-3: gavel-sand-brick-gravel, FB-4: gravel-sand-charcoal-gravel and FB-5: gravel-sand-(charcoal+brick)-gravel) and four macrophytes (MP-1: Typha latifolia, MP-2: Brachiaria mutica, MP-3: Canna indica and MP-4: Phragmites sp.) were evaluated for treating domestic waste water. After 120 days from the start, across treatment combinations, the plant in each column was uprooted, and the soil adhered to the root was collected in a polyethylene cover. The samples were brought to the laboratory, refrigerated, and then analysed for dehydrogenase, phosphatase, and urease activities, as well as for biofilm formation. Results revealed that the highest biofilm growth was observed on brick (1.18 and 0.05 mg g-1) had the maximum biofilm formation, followed by sand (0.68 and 0.04 mg g-1), charcoal (0.67 and 0.02 mg g-1), and gravel (0.31 and 0.01 mg g-1) at depths ranging from 0 to 5 and 5 to 15 cm, respectively. Since the CW can be implemented with flexibility, it can be used as the primary, secondary or tertiary treatment stage depending on the site and its configuration.

The effect of polyethylene cover intervention on ocular surface disorder of intensive care unit patients: a systematic review and meta-analysis

BackgroundPolyethylene covers have been proven to be effective in protecting the eyes in patients with decreased or disappeared blink reflexes, but their advantages compared to other conventional methods are still unclear. This systematic review and meta-analysis study aimed to elucidate the impact of polyethylene covers in the prevention of ocular surface disease (OSD) in patients admitted to the intensive care unit (ICU).MethodsWe searched the Scopus, PubMed, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) databases to identify randomized controlled trial studies. This study followed the PRISMA guidelines and used the Cochrane Collaboration tool to assess the risk of bias.ResultsThe findings were expressed as risk ratio (RR) with 95% confidence intervals. The incidence of OSD in the polyethylene cover group was lower than that in the eye drops group (RR = 0.27; 95% CI (0.07, 1.09), P = 0.07) and adhesive tape group (RR = 0.11, 95%CI (0.04, 0.31), P < 0:0001) but the polyethylene cover group showed no significant difference compared to the eye gel group (RR = 0.79, 95%CI (0.18, 3.51), P = 0.76) and the eye ointment group (RR = 0.85; 95% CI (0.36, 1.99), P = 0.71).ConclusionThis study showed that polyethylene covers, eye gels, and eye ointments had an equal effect on preventing OSD in ICU patients, and eye drops and adhesive tapes were relatively less effective. However, other intervention methods had not been compared due to the small number of articles. Hence, further studies should assess the available methods to choose the best practical method.

Heat distribution improvement with the implementation of polyethylene-covered water bolus into breast cancer hyperthermia

This paper presents the implementation of polyethylene-covered water bolus into a non-invasive breast cancer hyperthermia applicator. This modified hyperthermia applicator is introduced to improve the performance of hyperthermia by reducing or removing unwanted hotspots during hyperthermia treatment. This simulation-based experiment is carried out to observe the heating distribution of hyperthermia with water bolus coated by three different thicknesses of polyethylene cover or layer, which are 0.5mm, 0.8mm and 1.0mm. The solvent used in the water bolus is distilled water. The 915MHz microstrip antenna as a hyperthermia applicator and stage 2 breast cancer with a cancer depth of 28.6 mm to 73.6 mm is selected for this study. Based on the results, with the modified HTP integrated by water bolus, the heat pattern of hyperthermia simulation becomes more concentrated into the targeted cancer region, and unwanted hotspots nearby the skin area of breast tissue are removed. The 0.5mm thick polyethylene cover showed the best results with a focusing region between 29.4mm to 69.4mm compared with the result of hyperthermia without implemented water bolus, which heated the 26.6mm to 67.3mm region.

An Investigation of the Thermal Performance of a Tropical Greenhouse Constructed With an Earth Air Heat Exchanger

Abstract To maintain optimum plant growth temperature (i.e., 25–35 °C), the thermal performance of an earth air tunnel heat exchanger (EATHE)-integrated single-span saw-tooth greenhouse (GH) was assessed in peak summer. With the side and roof vents opened, natural ventilation due to wind and stack effect controlled the air movement and temperature inside the GH. In this configuration, the average temperature inside the GH remained higher than the ambient temperature by 1.5 °C for the entire period of the experiment. For EATHE (installed at a depth of 3.2 m) assisted GH with polyethylene (PE) cover, the air from the EATHE outlet entered inside the GH at 33 °C, and the average temperature within the GH was maintained at 4 °C lower than the ambient temperature. When the shading net was installed over the PE cover with the EATHE, the transmitted radiations into the GH were reduced from the roof, and the inside temperature was maintained 7 °C below the average ambient temperature (i.e., 45 °C). The measured temperatures along the length of the EATHE were compared with the indigenously developed code named PEAT (performance analysis of earth–air tunnel) and found to be in good agreement within ±4.5% deviation. The temperature distribution inside the GH was predicted using a computational fluid dynamics (CFD) model in ansys fluent with ±5% deviation from experimental results. With parametric analysis from the PEAT code and CFD model, the desired depth of the EATHE and the mass flowrate of air required to bring down the GH indoor temperatures to the optimum plant growth range were determined.

Real-Time Damage Self-Diagnosis and Self-Localization Brillouin Distributed Optical Fiber–Fiber-Reinforced Polymer Composite Smart Cables

Cables are important components of long-span space structures, cable-supported bridges, slopes, and so on. However, they often suffer from damage such as wire breakage, corrosion, and anchor head loosening, which threatens structural safety seriously. Therefore, it is very important to diagnose and localize their damage. To address this problem, a real-time damage self-diagnosis and self-localization smart cable is proposed. It is made of a polyethylene cover pipe and some parallel intelligent steel strands with the Brillouin distributed monitoring capability. Fiber-reinforced polymer (FRP) and optical fiber are put together in the thermosetting molding process to form the intelligent central wire of each intelligent steel strand. When the side wire of the steel strand reaches the ultimate load, the intelligent central wire only reaches about 50% of its ultimate load, so it can be used in the real-time monitoring of side wires. Numerical models of seven-wire steel strands with different lengths were established, and the broken wire damage was simulated by changing coupling conditions in single and multiple damage cases. To further verify the proposed smart cable, experiments were carried out based on two intelligent steel strands with the length of 34.5 m. Experimental damage cases were simulated by cutting side wires at different positions under different loads. Both numerical and experimental results show that the change in the tension strain of the intelligent central wire can indicate the damaged location of the broken side wire. For a healthy steel strand, the tension strain of the central wire is a constant value; for a damaged steel strand, damage can be localized according to the strain waveform of the intelligent central wire and its ratio of peak strain to stable strain. The proposed smart cable has functions of real-time stress self-sensing, damage self-diagnosis, damage self-localization, damage self-warning of any side wire, and its central wire has excellent corrosion resistance; it can be well used in life-cycle real-time structural health monitoring of cable structures/substructures, which dramatically reduces the probability of cable accidents, and lays a good foundation for smart civil structures.

Стрес-індуковані реакції мохів на періодичне короткочасне і тривале висушування залежно від водного режиму їхніх місцевиростань

Bryophytes are poikilohydric higher plants and their water content as well as metabolic activity depend on the water regime of the environment. The aim of the study was to establish the features of stress-induced reactions of mosses under controlled conditions of short-term and long-term drying depending on the water regime of their habitats. A culture of shoots of the same age from agar mediums the same level of relative humidity was used to study the effect of periodic drying. Dehydration was carried out within 24 hours, removing the polyethylene cover from the pots with moss culture. Plant watering was carried out twice a week in the variant of the experiment with short-term drying: immediately after dehydration and on the third day after drying. In the variant with long-term drying plants were watered once a week – on the third day after 24-hour dehydration. Control plants were sprayed twice a week. A significant decrease in the size of shoots, leaves and an increase in the density of moss turf under the influence of short-term and long-term drying have been established, based on the analysis of morphometric parameters of Barbula unguiculata Hedw. and Physcomitrella patens (Hedw.) Bruch &amp; Schimp. In the moss Weissia longifolia Mitt. long-term drying caused a slight increase in leaf size and elongation of shoots, comparing with control and short-term drying, and at the same time activated the formation of chloronеmal dendroids, which proved its greatest adaptability and ability to adapt to perio­dic changes in humidity. A higher sensitivity of the pigment system of B. unguiculata and P. patens to drying compared to W. longifolia was established. It was found that in the pigment system of the hygromesophytic moss P. patens the significant role belongs to chlorophyll b and pheophytin b, functioning of the assimilation complex of the xeromesophytic moss Barbula unguiculata depends on chlorophyll a and pheophytin a, in xerophytic moss W. longifolia – due to the stability of chlorophyll a and the strength of the bound of carotenoids with protein complexes of the pigment system. The dependence of the component composition of the pigment apparatus, the strength of the bond of pigment-protein complexes (PPC), the activity of chlorophyllase, and the total carbohydrate content of the studied mosses on the duration of drying and their species characteristics was determined.

Do Greenhouse Cover Materials Affect Cannabis Performance?

&#x0D; A greenhouse pot experiment was conducted in the Agricultural University of Athens in order to evaluate the effect of several greenhouse cover materials on the performance and yield of hemp. The experiment was set up in a completely randomized design (CRD) with five treatments/greenhouses (G1, G2, G3, G4/Control, and G5). Measurements included plant height, PAR (Photosynthetic Active Radiation), chlorophyll content, solar irradiance, soil and leaf temperature, and yield components (the number of buds, their weight, length, and compact index, CBD content, and CBD yield per plant). The results of the present study suggest that the different polyethylene cover films alter the environment within the greenhouse and thus, affect the agronomic characteristics and yield traits of hemp. G1 reported the best results as it increased soil temperature and PAR values by 11-16% and 50-110% respectively, compared to G4. Concurrently, the majority of the bud characteristics were significantly improved in G1. Even though further research should be conducted in order to define the most suitable films for greenhouse hemp production, our results indicate that the optical properties of the greenhouse cover materials affect its yield and should always be considered.&#x0D;

Effect of Polyethylene Cover for Preventing Corneal Injury in Critically Ill Patients: A Meta-Analysis.

Objective Polyethylene cover has been proved to be an effective method in protecting corneal, but its advantage compared to other conventional methods is still unclear. Our study is aimed at assessing clinical effects of polyethylene cover versus other methods in the prevention of corneal injury for critically ill patients. Methods We searched randomized controlled trials comparing polyethylene cover versus other methods for critically ill patients through the databases of PubMed, Embase, Web of Science, and China National Knowledge database. Forest plots and funnel plots were also performed on the included articles. Results were expressed as risk ratio (RR) with 95% confidence intervals. Results Eight studies were eventually identified. The incidence of corneal injury in the polyethylene cover group was lower than that in the eye drops group (RR = 0.24, 95% CI (0.12, 0.45), P < 0.0001) but had no significant difference when compared to the eye gel group (RR = 0.42, 95% CI (0.13, 1.34), P = 0.14) and the eye ointment group (RR = −0.61, 95% CI (0.23, 1.59), P = 0.31). Conclusion This study showed that polyethylene cover, eye gel, and eye ointment had an equal effect for preventing corneal injury in critically ill patients, and the effect of eye drops was relatively low. However, there were other intervention methods that had not been compared due to the small number of articles; further studies should be performed to assess which method was the best practice method.

Quality profile of different vegetables dried using simple solar dryers

Simple solar dryers with rotary chimney (SDR) and of tunnel type (SDT) with transparent polyethylene cover and black polyethylene cover (SDT-B) were tested in dehydrating tomato, onion, cabbage and spinach. Solar dryer temperatures increased by 5-15°C relative to that in open sun-drying. Tomatoes, onions, cabbage and spinach dried in 47, 44, 27 and 24 hours in SDR, respectively, and 51, 48, 31 and 28 hours in SDT, respectively, or 20-44 hours earlier than sun-drying. SDT-B took a longer time to dry cabbage and spinach than other solar dryers. Solar-dried onion and cabbage had high rehydration ratio. Colour (L*, a* and b*) of dried products was not affected except for SDT-B that maintained the green colour of spinach. However, vitamin C content as nutritional indicator decreased in the dried products. Future studies could look into techniques to minimise nutritional loss during solar drying of vegetables.

Effect of Particle Size and Transparent Solar Dryer Cover on the Proximate Analysis of Dried Onion

In this work, we investigate effect of particle size and transparent solar dryer cover on the proximate analysis of dried onion.&#x0D; A solar drying unit was developed and constructed for drying the of red onion slices in order to determine the proximate composition of fresh and dried red onion using multi-crop direct solar dryer. Also, the evaluation and effect of particles size and multi-crop transparent solar dryer cover on the proximate analysis of red onion during drying. Consequently, the higher efficiency of the solar collector was obtained at the higher airflow rate. The moisture content of dried onion slices was strongly affected by the thickness of the onion slices and the density of the polyethylene. The final moisture content of dried onion slices ranged from 10.85% to 13.01%, 4.95% to 6.01% ash, 4.69% to 5.26% fibre, 11.17% to 13.09% fat, 6.70% to 5.60% protein and 68.64% to 68.03% carbohydrate for particle sizes of 3 mm, 5 mm and 7 mm dry-basis depending on drying temperature cycle for low density polyethylene cover. While the final moisture content of dried onion slices ranged from 9.85% to 12.01%, 5.96% to 6.01% ash, 3.69% to 4.26% fibre, 13.17% to 12.09% fat, 5.70% to 6.60% protein and 61.64% to 58.03% carbohydrate for particle sizes of 3 mm, 5mm and 7mm dry-basis depending on drying temperature cycle for high density polyethylene cover.

Numerical and Experimental Study of Natural Convection in a Tunnel Greenhouse Located in South West Algeria (Adrar Region)

In this work, we propose to experimentally and numerically study the natural convection in laminar regime in an agricultural greenhouse located in South West of Algeria and more precisely in the Adrar area. The numerical study is two-dimensional and was carried out on a tunnel greenhouse with an area of 180m2 located in Adrar in the southwest of Algeria (Latitude: 27°52′27″N, longitude: 0°17′37″W, the laltitude above sea level is 257 m), with polyethylene cover and houses two rows of tomato plants. The experimental study was made during the winter or flowering period of tomato plants (February) when the temperature difference outside the greenhouse is maximum: T min = 3℃ at night and T max = 20℃ the day. We used a calculate code based on the finite element method to numerically simulate the phenomenon of heat transfer inside the greenhouse. The results of the numerical simulation are in the form of isotherms, streamlines and variations in temperature and speed in the greenhouse. The value of the temperature calculated by numerical simulation at the position where the sensor has been placed will be compared with that measured by the sensor. It was concluded that to have a favorable environment for the growth of tomatoes, we must keep the openings closed especially during the night without needing a heating system, especially in this region characterized by a hyper arid climate.

Organic photovoltaic modules integrated inside and outside a polytunnel roof

This paper investigates the differences electrical behavior and lifetime of organic photovoltaic (OPV) modules installed inside, on the outside of a polytunnel type greenhouse roof and on a fixed frame next to the polytunnel with the aim of finding an installation location that would reduce degradation and therefore prolong the lifetime OPV modules in a greenhouse application.The modules had different degradation rates, influenced by three factors: exposure to harsh weather conditions, mechanical stresses on the modules caused by the movement of the greenhouse plastic sheeting they were fixed to, and dust accumulation on the modules. Efficiency values of modules declined to 32%, 47% and 47% and fill factor values reduced by 33%, 21% and 21% for modules on top of the polytunnel, inside the polytunnel and on frames adjacent to the polytunnel respectively during the measurement period.Installing OPV modules inside a tunnel can increase module lifetimes and consequently increase the overall lifecycle output of the modules. Not fixing the OPV module directly to the polyethylene cover, thereby avoiding the stresses on the module due the film movement, could improve OPV lifetimes further.

The Effect of Three Eye Care Methods on the Severity of Lagophthalmos in Intensive Care Patients: A Randomized Controlled Clinical Trial.

Background Patients admitted to intensive care units are exposed to a variety of eye injuries such as lagophthalmos, which can lead to blindness. There is conflicting evidence regarding the effectiveness of different eye protection methods, and evaluations are ongoing. Therefore, this study was performed to compare the effect of “polyethylene cover,” “polyethylene cover plus artificial tear drops,” and “polyethylene cover plus Lubratex eye ointment” on the severity of lagophthalmos. Methods A total of 156 patients connected to ventilators were included in this clinical trial using the convenience sampling method. They were randomly divided into three groups: “polyethylene cover,” polyethylene cover plus artificial tear drops,” and “polyethylene cover plus Lubratex eye ointment.” In each group, one eye was regarded as control and the other eye as intervention. The control eye received routine interventions, including washing with normal saline. The eyes were examined daily by an ophthalmologist for 5 days for the occurrence of lagophthalmos. Results There was no statistically significant difference in the severity of lagophthalmos among the three groups “polyethylene cover,” “polyethylene cover plus artificial tear drop,” and “polyethylene cover plus Lubratex eye ointment.” However, clinically the severity of lagophthalmos was lower in the “polyethylene cover plus artificial tear drops” group than in the other two groups. Conclusion The results showed that the combination of polyethylene cover and artificial tears drops can be clinically effective in reducing the severity of lagophthalmos. Therefore, the use of this method is recommended for patients admitted to the intensive care unit. Similar studies are recommended.

Polyethylene eye-cover versus artificial teardrops in the prevention of ocular surface diseases in comatose patients: A prospective multicenter randomized triple-blinded three-arm clinical trial.

Polyethylene covers are claimed to be useful in preventing ocular surface diseases (OSD); however, evidence of their clinical efficacy is limited. This clinical trial aimed to compare the use of polyethylene eye covers and artificial teardrops versus normal saline on the incidence and severity of OSD in comatose patients. Of 90 eligible patients randomly assigned to three treatment groups, 79 patients completed the study, In group A, patients (n = 25) received artificial teardrops for left and normal saline for right eyes, in group B (n = 29) polyethylene covers for left and normal saline for right eyes, and in group C (n = 25) polyethylene covers for left and artificial teardrops for right eyes. As the patients were comatose, their blinding did not applicable, and a blinded observer evaluated the patients' eyes based on the Corneal Fluorescein Staining Pattern. The blinded analyzer analyzed collected data by SPSS-16 software at a 95% confidential level. The OSDs were observed in 65 (41.14%) out of 158 eyes examined. The artificial teardrop was more effective than the normal saline in group A, polyethylene eye cover was more useful than the normal saline in group B, and polyethylene eye cover was more effective than the artificial teardrop in group C in reducing the incidence of OSD (p< 0.01). Polyethylene eye covers had the most impact on reducing the severity of the OSD compared to the other interventions (p< .001). Polyethylene eye covers significantly reduced the incidence and severity of OSD. Using polyethylene cover is suggested as a safe, effective, and accessible eye care intervention for preventing OSD in comatose patients. (IRCT201609129014N115), Iranian Registry of Clinical Trials.

Effect of Design Parameters on Fresh Water Produced from Triangular Basin and Conventional Basin Solar Still

This paper reported the experimental testing of a triangular and conventional basin solar still (TBSS and CBSS). Solar basin and absorber are made of glass and a polyethylene cover, respectively, with an area of 0.25 m2. Square and triangular absorber with the same area of 0.25 m2 with square and triangular glass cover for condensation was fixed. Experimentations were conducted during the month of December 2018, and different natural criteria such as intensity, wind speed, and surrounding ambient temperatures were considered. Also, the modified model was compared to the CBSS on its performance and efficiency characteristics. The experimental results also revealed that the temperature of the water inside the TBSS was higher as compared with that of the CBSS. The daily yield obtained from CBSS and TBSS was found to be 2.7 and 3.2 kg/m2, respectively. Also, the daily efficiency of the TBSS was improved by 11.36% than the CBSS.

Effect of polyethylene cover on the treatment of exposure keratopathy in ICU.

Exposure keratopathy may lead to serious complications such as microbial keratitis, corneal perforation, and visual impairment if not treated. To compare the effect of carbomer eye drops when used alone and in combination with polyethylene covers in the healing of exposure keratopathy. A single blind randomized-controlled trial (RCT) in two intensive care units (ICUs) was carried out in a university hospital in Western Turkey between September 2011 and December 2012. The control group received only carbomer, eye drops while the intervention group received both carbomer eye drops and polyethylene covers. The primary outcome was the decrease or absence of corneal damage, which refers to healing. Corneal damage was followed up with a fluorescein dye test (decrease/absence of the corneal staining) by the same ophthalmologist for 10 days. A total of 43 corneas in 24 patients were studied. Corneal epithelial defects decreased in the intervention group by day 2 and progressed or remained unchanged in the control group every day (P= .001). Patient characteristics did not affect the grade ranges of corneal staining in the groups except for level of consciousness. Carbomer eye drops, when used in combination with polyethylene covers, were effective in managing exposure keratopathy. Corneal damage and further ocular complications can be reduced with the utilization of polyethylene covers in nursing care and treatment.
