Patient satisfaction and follow-up adherence to glaucoma case management clinic in China

AIM:To assess glaucoma patient satisfaction and follow-up adherence in case management and identify associated predictors to improve healthcare quality and patient outcomes.METHODS:In this cross-sectional study,a total of 119 patients completed a Patient Satisfaction Questionnaire-18 and a sociodemographic questionnaire.Clinical data was obtained from the case management system.Follow-up adherence was defined as completing each follow-up within±30d of the scheduled time set by ophthalmologists during the study period.RESULTS:Average satisfaction scored 78.65±7,with an average of 4.39±0.58 across the seven dimensions.Age negatively correlated with satisfaction(P=0.008),whilst patients with follow-up duration of 2 or more years reported higher satisfaction(P=0.045).Multivariate logistics regression analysis revealed that longer follow-up durations were associated with lower follow-up adherence(OR=0.97,95%CI,0.95-1.00,P=0.044).Additionally,patients with suspected glaucoma(OR=2.72,95%CI,1.03-7.20,P=0.044)and those with an annual income over 100000 Chinese yuan demonstrated higher adherence(OR=5.57,95%CI,1.00-30.89,P=0.049).CONCLUSION:The case management model proves effective for glaucoma patients,with positive adherence rates.The implementation of this model can be optimized in the future based on the identified factors and extended to glaucoma patients in more hospitals.

Shifting the Paradigm:A Fresh Look at Physical Activity Frequency and Its Impact on Mental Health,Life Satisfaction,and Self-Rated Health in Adolescents

As adolescent mental health problems are becoming a more serious issue globally,this paper explores the relationship of physical activity in adolescents and its frequency on mental health as well as examines the mediating effects of life satisfaction and self-rated health in order to provide a reference for the promotion of mental health in adolescents.A sample of 3578 Chinese high school students completed questionnaires assessing their mental health,physical activity frequency,life satisfaction,and self-rated health.The mean SCL-90 value for adolescents was found to be 1.629%,and 24.73%of adolescents had varying degrees of mental health issue.Increased physical activity frequency is positively associated with improved mental health(p<0.001).Additionally,life satisfaction and self-rated health were found to play significant mediating roles in the relationship between physical activity frequency and mental health.Specifically,low-frequency physical activity had the most pronounced mediating effect on mental health through life satisfaction,while high-frequency physical activity exerted the most significant mediating effect on mental health through self-rated health.These findings underscore the importance of promoting physical activity among adolescents and highlight the distinct pathways through which physical activity frequency can influence mental health outcomes.Further research is needed to explore these relationships in diverse populations and settings,as well as to develop targeted intervention.

Expectations and Level of Satisfaction of the Patient with Parkinson’s Disease Undergoing Deep Brain Stimulation Surgery at the National Institute of Neurology and Neurosurgery

Background: Deep brain stimulation (DBS) is an established treatment for patients with advanced Parkinson’s disease (PD). Reports show continued patient satisfaction after surgery despite not maintaining clinical improvement as measured by evolution scales. Objectives: The present study sought to explore expectations and level of satisfaction in patients after DBS surgery with a semi-structured questionnaire and subsequent correlation with functional scales, Quality of Life (QoL), and motor and non-motor symptoms. Methods: We performed descriptive statistics to represent demographic data, Wilcoxon rank tests to determine significant differences, and Spearman correlation between the applied scales. Results: We evaluated 20 patients with a history of DBS surgery. 45% were female, with a mean age of 55.7 ± 14.15 years, a mean disease duration of 13.42 ± 8.3 years, and a mean time after surgery of 3.18 ± 1.86 years. Patients reported surgery meeting expectations in 85.5% and continued satisfaction in 92%. These two variables showed a significant correlation. Conclusions: This sample of patients remained satisfied after DBS surgery, although we found no differences in motor and non-motor clinimetric scales. Further studies are needed to confirm the importance of assessing quality of life in patients with DBS.

An Integrated FCEM-AHP Approach for Borrower’s Satisfaction and Perception Analysis of Microfinance Institution

Themain objective of this paper is to present an integrated approach to evaluate the level of satisfaction of borrowers with the products and services of microfinance institutions(MFI)at different criterion levels.For this,the study adopts the concept of FCEM(Fuzzy Comprehensive EvaluationMethod)in concurrence with the AHP(Analytical Hierarchy Process).In our day-to-day situation,the researchers have made many efforts to assess the impact of Microfinance on poverty reduction,but borrowers’satisfaction is always overlooked.Since the multiple factors impact the borrower’s satisfaction,each factor is made of different items.Thus,as the factors items increase,many uncertainties are created,and hence this will make the decisionmaking unsmooth or imprecise.To describe this,the FCEM method deals with the vagueness in the collection information phase.However,the AHP has been utilized to determine the objective weights of each factor.The presented integrated framework has been illustrated with a case study and presented their results.The study’s managerial benefit is also reported to address the situation.

Patients’ Perception and Satisfaction with Waiting Time, and Facilities Available in a State Teaching Hospital Eye Clinic, Southeast, Nigeria

Patients’ satisfaction with waiting time and the facilities in eye clinics is an important indication of the patients’ assessment of the quality of service in the eye clinic. In this study, waiting time was defined as time spent from arrival to time when the patient is seen by a doctor. Some factors that affect patients’ waiting time in health clinics include: healthcare setting, availability of adequate resources and personnel, efficient deployment of available resources and competence of healthcare workers, and punctuality of healthcare workers. The physical environment, comfort of patients, and level of infrastructure in the hospital also influence patients’ satisfaction. This observational, descriptive, cross-sectional study was conducted among patients that attended an eye care clinic, in a tertiary hospital, and 348 respondents were interviewed. Most of the respondents were aged 40 years and above (64.4%), females (63.5%), Igbos by tribe (94.8%), married (63.2%), Christians (96.6%), and had at least a secondary level of education (78.4%). Most perceived waiting time as being very long or long (60.1%), and only 48.8 were satisfied or very satisfied with the waiting time. Most also perceived the cleanliness of the eye clinic as being clean or very clean (85.0%), and 70.7% perceived the ventilation as being adequate or very adequate. The majority reported that a health talk was given (71.6%), and 62.7% were satisfied or very satisfied with the talk. More respondents (46.8%) perceived the waiting space as very inadequate or inadequate, as against 43.4% that perceived it as adequate or very adequate. More reported that prescribed drugs were completely unavailable or few available (48.0%), while 42.3% reported drugs as being reasonably or completely available. It is important that management of health facilities that offer eye care services, work towards improving patients’ perception and satisfaction with services provided in the eye clinics.

Occurrence of Salmonella Enteric Serovar Typhi Antibodies among Blood Donors in Ghana

Background: Donated blood contaminated with S. Typhi can cause post-transfusion sepsis. This study aimed to determine the correlation between some risk factors of typhoid fever and seroprevalence of antibodies against S. Typhi among blood donors. Methodology: Following informed consent, socio-demographic and information on risk factors of typhoid infection was obtained using pre-structured questionnaires from 400 apparently healthy blood donors at the Tema General Hospital. Blood was also collected for serology and cultured for identification of pathogens by standard bacteriological method. Results: Blood culture did not reveal any S. Typhi isolate out of the tested 400 (348 males and 52 females) samples from apparently healthy blood donors. However, IgM and IgG antibody seroprevalence of 9.3% and 3.5% were detected. Age group of 17 - 24 years was the highest risk group, persons with a history of typhoid infection, and sources of drinking water were major risk factors for typhoid infection. It was also observed that prevalence of IgM was highest among new donors (62.2%), but lower in donors with a history of 1 to 3 blood donations (32.4%) and least among regular donors (>3 donations (5.4%)). In addition, typhoid prevention awareness and typhoid knowledge (knowledge about typhoid transmission) among the donors were poor (4.3% and 5.9% respectively). Conclusions: This study has shown an overall seroprevalence of 9% and 3.5% for IgM and IgG antibodies respectively among blood donors in the Tema area in Ghana. We advocate for the mandatory screening of donor units intended for transfusion for S. Typhi. Furthermore, there is an urgent need for the health education of all persons in Ghana on preventive measures and the spread of S. Typhi.

Prevalence and Social Demographic Factors Associated with Secondary Traumatic Stress, Burnout and Compassion Satisfaction among Nurses at Selected Teaching Hospitals in Lusaka, Zambia

Introduction: Nurses’ constant exposure to severe human suffering within constrained health care environments places them at risk for developing Secondary Traumatic Stress and Burnout. The current study therefore sought to establish the prevalence and social demographic factors associated with Secondary Traumatic Stress, Burnout and Compassion Satisfaction among Nurses working at selected Teaching Hospitals in Lusaka, Zambia. Methods: A correlational design employing a self-administered questionnaire adapted from version five of the Professional Quality of Life scale was used to collect data from 250 nurses drawn using proportional stratified sampling method. The resulting data were analyzed using version 23 of the Statistical Package for Social Sciences (SPSS). Hierarchical multiple linear regression analysis was used to identify predictors of Secondary Traumatic Stress and Burnout. Findings: Whilst the majority of respondents reported average levels of Secondary Traumatic Stress and Burnout, about a quarter reported high Secondary Traumatic Stress and Burnout scores at 23% and 26% respectively. Only 81 (32.4%) scored high on Compassion Satisfaction. Social demographic factors including;working in the main Intensive Care Unit, and being married accounted for the greatest variance in Secondary Traumatic Stress (R2 = 0.237, p Conclusion: Findings of the current study signify a need to institute measures to help nurses cope with the deleterious psychological effects of constant engagement with those in distress and to foster Compassion Satisfaction.

Reasons and effects of the decline of willing related potential living kidney donors

BACKGROUND Although the availability of related living donors(LDs)provides a better chance for receiving kidney transplantation(KT),the evaluation protocols for LD selection remain a safeguard for the LD’s safety.These protocols are variable from one center to another,resulting in variable rates of decline of the potential LDs(PLDs).The decline of willing PLDs may occur at any stage of evaluation,starting from the initial contact and counseling to the day of operation.AIM To identify the causes of the decline of PLDs,the predictors of PLD candidacy,and the effect on achieving LDKT.METHODS A retrospective study was performed on the willing PLDs who attended our outpatient clinic for kidney donation to their related potential recipients between October 2015 and December 2022.The variables influencing their candidacy rate and the fate of their potential recipients were studied.Two groups of PLDs were compared:Candidate PLDs after a completed evaluation vs non-candidate PLDs with a complete or incomplete evaluation.A multivariate logistic regression was performed to assess the factors contributing to the achievement of PLD candidacy.RESULTS Of 321 willing PLDs,257 PLDs(80.1%)accessed the evaluation to variable extents for 212 potential recipients,with a mean age(range)of 40.5±10.4(18-65)years,including 169 females(65.8%).The remaining 64 PLDs(19.9%)did not access the evaluation.Only 58 PLDs(18.1%)succeeded in donating,but 199 PDLs(62.0%)were declined;exclusion occurred in 144 PLDs(56.0%)for immunological causes(37.5%),medical causes(54.9%),combined causes(9.7%),and financial causes(2.1%).Regression and release occurred in 55 PLDs(17.1%).The potential recipients with candidate PLDs were not significantly different from those with non-candidate PLDs,except in age(P=0.041),rates of completed evaluation,and exclusion of PLDs(P<0.001).There were no factors that independently influenced the rate of PLD candidacy.Most patients who failed to have KT after the decline of their PLDs remained on hemodialysis for 6 mo to 6 years.CONCLUSION The rate of decline of willing related PLDs was high due to medical or immunological contraindications,release,or regression of PLDs.It reduced the chances of high percentages of potential recipients in LDKT.

These findings can be used to inform the development of policies and interventions aimed at enhancing healthcare quality in Saudi Arabia.

Seroprevalence of Viral Hepatitis B and C among Blood Donors at the Agadir Regional Transfusion Center

Introduction: The prevention of transmission of infections transmitted by blood transfusion depends on the correct selection of donors and the performance of adequate serological tests for the detection of pathogens, in particular viral hepatitis B and C viruses. The main objective of our study was to evaluate the seroprevalences of viral markers B and C in blood donors in the Agadir region. The secondary objectives were to evaluate these prevalences according to the socio-demographic characteristics of the donors and to evaluate the seroprevalence of other markers, in particular the human immunodeficiency virus. Methods: A retrospective analysis of files from the blood donor registers of the Agadir regional transfusion center, covering the period from 1 January to 31 December 2020, was conducted. Results: The study included 13,092 donors, the mean age was 34 ± 11, the M/F sex ratio was 2.6. The overall seroprevalences of HBsAg, anti-HCV, anti-HIV were respectively: 1.3%, 0.2% and 0.3% respectively. For HBsAg, the prevalence was higher in men (p = 0.007). The prevalence of anti-HCV was higher in rural areas than in urban areas (p Conclusion: The low prevalences of viral markers B and C in our study compared to those recorded in the general Moroccan population reflect the effectiveness of preventive measures with regard to donor selection.

Superior aggregation, morphology and photovoltaic performance enabled by fine tuning of fused electron-deficient units in polymer donors

Copolymerization of an electron-rich donor(D)unit with an electron-deficient acceptor(A)unit to construct efficient D-π-A-πtype donors is an effective strategy for organic solar cell applications.The electron-deficient unit fusion,endows extendedπ-conjugation plane and insures excellent photoelectronic property,has great advantages to build A moiety and gradually receives considerable attention.In this work,we adopt benzo[2,1-b:3,4-b’]dithiophene and benzopyrazine(BP),benzothiadiazole(BT)and benzoselenadiazole(BS)to cleverly construct a series of fused A units with different electrondeficient ability,and further synthesize three polymer donors PBDP-BP,PBDP-BT,and PBDP-BS,respectively.The relationships between structure and performance were systematically investigated.PBDPBT shows a moderate aggregation behavior in both solution and film,and the highest hole mobility among the three polymers.After blending with Y6,the PBDP-BT:Y6-based film has the strongest absorption,favorable compatibility,superior crystallinity,and uniform phase separation morphology compared with PBDP-BP or PBDP-BS based blend films.Thus,the device based on PBDP-BT:Y6 has the highest and balanced charge mobility,suppressive recombination,reduced energy loss and achieves an outstanding PCE of 15.14%,which is superior to PBDP-BP:Y6(8.55%)and PBDP-BS:Y6(6.85%).These results provide learnable guidelines for future fused electron-deficient unit-based donor design for photovoltaic application.

Post-transplant biliary complications using liver grafts from deceased donors older than 70 years:Retrospective case-control study

BACKGROUND The shortage of liver grafts and subsequent waitlist mortality led us to expand the donor pool using liver grafts from older donors.AIM To determine the incidence,outcomes,and risk factors for biliary complications(BC)in liver transplantation(LT)using liver grafts from donors aged>70 years.METHODS Between January 1994 and December 31,2019,297 LTs were performed using donors older than 70 years.After excluding 47 LT for several reasons,we divided 250 LTs into two groups,namely post-LT BC(n=21)and without BC(n=229).This retrospective case-control study compared both groups.RESULTS Choledocho-choledochostomy without T-tube was the most frequent technique(76.2%in the BC group vs 92.6%in the non-BC group).Twenty-one patients(8.4%)developed BC(13 anastomotic strictures,7 biliary leakages,and 1 nonanastomotic biliary stricture).Nine patients underwent percutaneous balloon dilation and nine required a Rouxen-Y hepaticojejunostomy because of dilation failure.The incidence of post-LT complications(graft dysfunction,rejection,renal failure,and non-BC reoperations)was similar in both groups.There were no significant differences in the patient and graft survival between the groups.Moreover,only three deaths were attributed to BC.While female donors were protective factors for BC,donor cardiac arrest was a risk factor.CONCLUSION The incidence of BC was relatively low on using liver grafts>70 years.It could be managed in most cases by percutaneous dilation or Roux-en-Y hepaticojejunostomy,without significant differences in the patient or graft survival between the groups.

Public satisfaction with the quality of First Health Facility Services in Indonesia: Does sociodemographic matter?

Objective:To investigate individual characteristics related to satisfaction with the quality of First Health Facility Services(FHFS)in Indonesia.Methods:This cross-sectional study analyzes national representation data.Meanwhile,the study involved 9846 representative respondents in 2019.Respondent’s satisfaction with FHFS based on the five dimensions of service quality(SERVQUAL)is a dependent variable.Independent variables consist of sex,marital status,age,education,employment,insurance ownership,and economics.The study used multivariate logistic regression to explain the relationship between individual characteristics and FSHS quality.Results:77.3%Respondents were satisfied with FHFS,with the highest order of satisfaction dimensions being assurance(59.4%),empathy(57.3%),reliability(53.6%),responsiveness(52.7%),and then tangibility(49.1%).Multivariate logistic analysis showed that divorce was 1.48 more likely than never-married to be satisfied(95%CI 1.17-1.87).Employees were 0.77 less likely than the unemployed to get satisfied(95%CI 0.70-0.86).Respondents with higher education was 0.82 less likely than those with primary education to be satisfied(95%CI 0.67-0.99).Meanwhile,respondents who had government-run insurance were 1.61 more likely than uninsured to be satisfied(95%CI 1.42-1.80).Moreover,the rich were 0.82 less likely than the poor to get satisfied(95%CI 0.73-0.92).Conclusions:Community satisfaction with FHFS is generally high,though some areas could be improved.Demographic factors are still strongly related to satisfaction ratings.The government can assess the quality of services in accordance with standards and disseminate information about service standards for primary facilities to all levels of society,ensuring that service satisfaction is rated as good by all groups.

Investigation and Analysis of HIV Infection among Unpaid Blood Donors in Wuzhou City

Objective: To take the unpaid blood donors in Wuzhou City as the research object, analyze the characteristics and prevalence of HIV infection, further explore its epidemiological characteristics, and lay a solid foundation for the recruitment of unpaid blood donors and the safety of blood transfusion, so as to reduce the risk of HIV transmission through blood transfusion. Methods: This paper collected the anti-HIV test results of unpaid blood donors and the confirmation results of reactive samples from 2015 to 2020, and carried out statistical analysis on the relevant information of positive samples. Result: From 2015 to 2020, a total of 233,242 unpaid blood donors were tested, and the positive rate of anti-HIV initial screening was 0.057% (132/233,242), and the positive rate of anti-HIV confirmed was 0.022% (51/233,242);the comparison of positive rates in each year was P < 0.05. Among the total number of infections, 76.47% (39/51) of confirmed positive persons were infected with HIV alone, followed by combined TP infection, accounting for 15.69% (8/51);for the people between 46 and 55 years old, the infection rate was the highest, reaching 37.3%;and more men (90.2%) were infected than women. In terms of education background, junior high school and below were the majority, accounting for 58.83% of the total;in terms of marital status, the number of unmarried people was 27, accounting for 52.9%. In terms of occupation, there were two main groups: farmers and workers, accounting for 66.7% of the total number of infections, and students accounting for 15.7%. Among the confirmed positives, the proportion of first-time blood donors and whole blood donors was higher than that of those who donated blood again or donated component blood. Conclusion: The situation of HIV infection among unpaid blood donors in Wuzhou City was relatively stable from 2015 to 2020, with no significant change in the absolute number of infected people compared to the previous period (the HIV infection rate from 2010 to 2013 was 0.03%), and most of them were males, unmarried people and those with low education. Therefore, attention must be paid to the consultation and recruitment of blood donors before blood donation, as well as the HIV screening in the laboratory after blood donation, so as to ensure the safety of clinical blood use.

Association between Support and Satisfaction with Life among Older Adults in Ekiti, Nigeria: Findings and Implications

Many developing countries like Nigeria lack policy for the care of the older adults and this creates major challenges for the elderly population. The traditional family institution and community support that used to be safety nest are being adversely affected by westernization. This development might have adverse effect on life satisfaction among the older adults. This hospital based cross-sectional study was designed to determine the association between support and life satisfaction among older adults. A total of 128 subjects participated in the study out of which 28.9% were satisfied with life. Expectation of support was mainly from the family, less from the community and very low from the government. The level of support received from all sources generally fell short of expectations. Marital status and source of livelihood were significantly associated with life satisfaction. There is inadequate social support from the government and support from family and community fell below expectations. Expectations of support were the most strongly correlated with life satisfaction. Support for older adults must be addressed in order to meet their expectations and improve their level of satisfaction with life.

Research on Multi-Objective Optimization Model of Industrial Microgrid Considering Demand Response Technology and User Satisfaction

In the process of wind power,coal power,and energy storage equipment participating in the operation of industrial microgrids,the stable operation of wind-storage industrial microgrids is guaranteed by considering demand response technology and user satisfaction.This paper firstly sorts out the status quo of microgrid operation optimization,and determines themain requirements for user satisfaction considering three types of load characteristics,demand response technology,power consumption benefit loss,user balance power purchase price and wind power consumption evaluation indicators in the system.Secondly,the operation architecture of the windstorage industrialmicrogrid is designed,and themulti-objective optimizationmodel of the wind-storage industrial microgrid is established with the comprehensive operating cost and user satisfaction as the target variables,and the corresponding solution method is mentioned.Finally,a typical wind-storage industrial microgrid is selected for simulation analysis,and the results showthat,(1)Considering the demand response technology,the comprehensive operating cost of the wind-storage industrial microgrid per day is 5292.63 yuan,the user satisfaction index is 0.953,and the wind power consumption rate reaches 100%.(2)By setting four scenarios,it highlights that the grid-connected operation mode is superior to the off-grid operation mode.Considering the demand response technology,the load curve can be optimized,and the time-of-use electricity price can be fully used to coordinate the operation of each unit,which enhances the wind power consumption capacity.The compromise solution of the system comprehensive operating cost and user satisfaction under the confidence level of 0.95 is obtained,namely(5343.22,0.94).(3)The frontier curve shows that in the process of model solving,it is impossible to optimize any sub-objective by changing the control variables,which proves that there is a close relationship between the comprehensive operating cost of the system and the confidence level,which can provide effective guidance for the optimal operation of industrial microgrids.
