Factors influencing discharge readiness among patients with mild-to-moderate ischemic stroke:a cross-sectional study

Objective:To describe discharge readiness and determine whether self-efficacy,social support,and the quality of discharge teaching can predict discharge readiness among patients with mild-to-moderate ischemic stroke.Methods:A total of 120 patients with mild-to-moderate ischemic stroke were recruited using simple random sampling.Five instruments,namely,the Demographic Data Questionnaire,the Chinese version of the Readiness for Hospital Discharge Scale(RHDS_C),the SelfEfficacy for Managing Chronic Disease 6-Item Scale(SES6),the Perceived Social Support Scale(PSSS),and the Quality of Discharge Teaching Scale(QDTS),were used for data collection.Descriptive statistics and standard multiple linear regression were used for data analysis.Results:The mean score of discharge readiness among patients with mild-to-moderate ischemic stroke was at a moderate level(M=7.6,SD=0.92),and 75.8%of the participants felt ready for discharge.Standard multiple linear regression revealed that selfefficacy(β=0.62,P<0.001)and the quality of discharge teaching(β=0.28,P<0.001)were the influencing factors.However,social support could not predict discharge readiness significantly.All the factors combined explained 64.9%of the variance in discharge readiness.Conclusions:Intervention programs aimed at improving self-efficacy and the quality of discharge teaching may be helpful in promoting discharge readiness in patients with mild-to-moderate ischemic stroke,especially in coping ability.

Sexual spores in edible mushroom: bioactive components, discharge mechanisms and effects on fruiting bodies quality

Edible mushroom sexual spores have been gaining more interest due to their bioactive components and functions.Spore discharge(SD)is an important factor affecting the quality of edible mushrooms.In this review,the bioactive nutrients of sexual spores of edible mushrooms were summarized,the SD mechanism was described,and the relationship between postharvest SD and the quality of edible mushrooms was analyzed.Spores contain various bioactive nutrients that are benefi cial to the human body.Mature mushrooms can actively discharge spores in a process affected by light,relative humidity,and temperature.During storage,the physiological metabolism of spore-bearing gill tissue is vigorous,promoting the release of postharvest spores and changing the nutritional value of fruiting bodies.The flavor of the fruiting bodies also varied signifi cantly during SD.Edible mushroom sexual spores have the potential to become new raw materials for functional food and medical resources.Research on the effect of the mechanism of SD on the quality of edible mushrooms and the development of SD regulation technology may be a new trend in the quality control of edible mushrooms,which will promote the development of the edible mushroom industry.

Evaluation of trans-ferulic acid degradation by dielectric barrier discharge plasma combined with ozone in wastewater with different water quality conditions

In this study, dielectric barrier discharge plasma and ozone(O_3) were combined to synergistically degrade trans-ferulic acid(FA), and the effect of water quality on FA degradation was studied. The results showed that 96.9% of FA was degraded after 40 min treatment by the plasma/O_3 process. FA degradation efficiency increased with the p H values. The presence of suspended solid and humic acid inhibited FA degradation. FA degradation efficiency increased as the water temperature increased to 30 °C. However, the further increase in water temperature was adverse for FA degradation. Effects of common inorganic ions on FA degradation were also investigated. The addition of Cl^- inhibited the FA degradation, whileCO_3^(2-) had both negative and positive influences on FA degradation.NO_3^- andSO_4^(2-) did not have significant effect on FA degradation. Fe^(3+)and Cu^(2+)benefited FA degradation through the Fenton-like and catalytic ozonation reactions.

Water Quality from the Purification Unit of Thiakhar (Diourbel, Senegal) and Impact of Discharges from Treatment on Water Resources

The installation of a purification unit since 2008 in the village of Thiakhar has improved the physico-chemical and bacteriological quality of the water supply. However about 55% of the raw water comes out of the unit as discharges (approximately 14 m3 per day) highly concentrated in fluoride and chloride ions. Based on historical samples, we find that the volumes of water consumed together with the volumes of water discharged are increasingly significant from year to year. The storage of waste water is carried out in a septic tank connected to a leaking cesspool sink. Significant excesses of these discharges are visible on the site and a flow of concentrate is observed creating a puddle of water that attracts birds and straying cattle. The study describes the following substantial impacts on the natural and human environment: 1) contamination of groundwater, 2) soil salinization 3), impact on flora and fauna, 4) impact on health. The study concludes by identifying measures to mitigate the negative impacts related to the discharges and by proposing alternative solution.

Analysis of the Current Status and Influencing Factors of the Readiness for Discharge of Patients after Prostate Cancer Surgery Based on the Concept of Enhanced Recovery after Surgery (ERAS)

Objective To investigate the level of readiness for discharge of patients after prostate cancer surgery based on the concept of Enhanced Recovery After Surgery (ERAS), and to explore its influencing factors, so as to provide references for improving the readiness for discharge of patients after prostate cancer surgery. Methods The general information questionnaire, the discharge preparation scale, and the discharge guidance quality scale were used to investigate 119 patients discharged from the urological surgery department of a tertiary A-level hospital in Guangzhou after radical prostatectomy. Results The total score of discharge readiness of patients after radical prostatectomy was 147.74 ± 35.71 points, which was at a lower middle level and the total score of discharge guidance quality was 180.68 ± 38.91 points, which was at a medium level. Multiple linear regression analysis showed that education level, family monthly income, Gleason score, whether to perform lymphatic dissection, whether to discharge with a urinary catheter, and the quality of discharge guidance were the main factors influencing the readiness for discharge of patients after prostate cancer surgery. Conclusion In clinical nursing work, it is necessary to implement individualized health education according to the characteristics and needs of different patients to improve the level of preparation for discharge of patients after prostate cancer surgery.

Battery Voltage Discharge Rate Prediction and Video Content Adaptation in Mobile Devices on 3G Access Networks

According to Cisco, mobile multimedia services now account for more than half the total amount of Internet traffic. This trend is burdening mobile devices in terms of power consumption, and as a result, more effort is needed to devise a range of pow- er-saving techniques. While most power-saving techniques are based on sleep scheduling of network interfaces, little has been done to devise multimedia content adaptation techniques. In this paper, we propose a multiple linear regression model that predicts the battery voltage discharge rate for several video send bit rates in a VoIP application. The battery voltage dis- charge rate needs to be accurately estimated in order to esti- mate battery life in critical VoIP contexts, such as emergency communication. In our proposed model, the range of video send bitrates is carefully chosen in order to maintain an acceptable VoIP quality of experience. From extensive profiling, the empir- ical resuhs show that the model effectively saves power and pro- longs real-time VoIP sessions when deployed in power-driven adaptation schemes.

Factors Influencing Readiness for Hospital Discharge among Patients Undergoing Breast Cancer Surgery

Background: Breast cancer has become an important disease burden harmful to women’s health. The treatment of breast cancer is mainly surgical treatment. In the context of enhanced recovery after surgery, the average length of hospital stay has been reduced, so there is increasing concern about postoperative patient discharge readiness. Objective: To identify factors influencing readiness for hospital discharge among patients having undergone breast cancer surgery and to explore the relationship between discharge readiness and the quality of discharge teaching. Methods: A total of 99 patients after breast cancer surgery at a regional tertiary medical tumor center in Guangzhou between June 2021 and December 2021 were collected using the convenience sampling method. A general data questionnaire, readiness for hospital discharge scale, and quality of discharge teaching scale were used to conduct a questionnaire survey on the subjects. Results: 83.8% of the patients feel ready for discharge, and the score of discharge readiness was 155.98 ± 28.87. The patients’ content received and the skills in teaching delivery were the influencing factors of discharge readiness. Discharged with a drainage tube was an independent factor of discharge readiness. Conclusions: Readiness for hospital discharge among patients undergoing breast cancer surgery was above medium level, and perfect intervention measures should be formulated for the influencing factors of discharge readiness. Especially, specific executable safeguard measures should be formulated for patients who are discharged early after surgery to promote the safety of home care.

Treatment of Microalgae in Ballast Water Using Hydroxyl Radical in Accordance with the D-2 Ballast Water Discharge Standard

The effect of hydroxyl radical(·OH) on microalgae in ballast water is experimentally investigated. An ?OH plasma generator, which has a thin plate discharge Ag electrode covered by two α-Al2 O3 dielectric layers, is built. The plasma generator is filled with O2 and gaseous H2 O and is powered by a homemade power supply. ?OH radicals are generated by a series of plasma reactions and then dissolved into ballast water to kill microalgae. The maximum density of the killed microalgae is about 11 000 cells per milliliter. At this density, the microalgae are not reactivated at the 48th hour and the 120th hour in the treated ballast waters, and the content of chlorophyll in these microalgae decreases by 100%. The water quality returns to a normal level after 120 hours without secondary pollution of aquatic organisms and environment. These results show that the requirements of the D-2 ballast water discharge standard defined by the International Maritime Organization(IMO) are satisfied with the proposed treatment, and that ·OH is an ideal substance for killing microalgae during ballast water replacement of ships.
