Mediating role of health literacy in the relationship between social isolation and psychological distress among pre-frail older adults

BACKGROUND Frailty has become a significant public health issue.The recent increase in the number of frail older adults has led to increased attention being paid to psycho-logical care services in communities.The social isolation of pre-frail older adults can impact their psychological distress.AIM To explore the mediating effect of health literacy between social isolation and psychological distress among communitydwelling older adults with pre-frailty.METHODS This descriptive cross-sectional study was conducted with 254 pre-frail older individuals aged 60 years and over.Social isolation,health literacy,and psycholo-gical distress were comprehensively measured using the Lubben Social Network Scale-6,12-item Short-Form Health Literacy Questionnaire,and the Kessler Psy-chological Distress Scale-10.Data were evaluated using the SPSS 27.0 package program and the PROCESS macro tool.Descriptive statistical analyses,correlation analyses,and bootstrap mediation tests were used to assess associations between the variables.RESULTS The results showed that social isolation had an effect on health literacy among pre-frail older adults(β=0.240,P<0.001),social isolation impact on psycho-logical distress pre-frail older adults(β=-0.415,P<0.001);health literacy was identified effect on psychological distress among pre-frail older persons(β=-0.307,P<0.001).Health literacy partially mediated the relationship between social isolation and psychological distress among community-dwelling older adults with pre-frailty,with a mediation effect of-0.074,accounting for 17.83%of the total effect.

The Relevance of Vygotsky＇s Developmental Perspective to the Debate on Methodology in Psychological Science

Throughout his work, Lev S. Vygotsky （1896-1934） pursued the objective of reformulating psychological theory. His historical-cultural analysis of the ＂crisis in psychology＂ showed that, beyond contradictions between the two main methodological currents---＂objective/explanatory＂ and ＂subjective/intuitive＂--psychology is primarily influenced by its empirical-sensory foundations. This influence is actually at the origin of the disagreement since it maintains the obligation for the two currents to make reference to empirical-sensory data. Only a general model of the developing human being, assessed by its usefulness, will allow reorienting psychology towards a broader science. This would lead to a general theory of psychology, which could then facilitate the search for tools for an indirect method enabling it to go beyond empiricism.

Psychological interventions for depression in children and adolescents:A bibliometric analysis

BACKGROUND Depression has gradually become a common psychological disorder among children and adolescents.Depression in children and adolescents affects their physical and mental development.Psychotherapy is considered to be one of the main treatment options for depressed children and adolescents.However,our understanding of the global performance and progress of psychological interventions for depression in children and adolescents(PIDCA)research is limited.AIM To identify collaborative research networks in this field and explore the current research status and hotspots through bibliometrics.METHODS Articles and reviews related to PIDCA from January 2010 to April 2023 were identified from the Web of Science Core Collection database.The Charticulator website,CiteSpace and VOSviewer software were used to visualize the trends in publications and citations,the collaborative research networks(countries,institutions,and authors),and the current research status and hotspots.RESULTS Until April 16,2023,1482 publications were identified.The number of documents published each year and citations had increased rapidly in this field.The United States had the highest productivity in this field.The most prolific institution was the University of London.Pim Cuijpers was the most prolific author.In the context of research related to PIDCA,both reference co-citation analysis and keywords co-occurrence analysis identified 10 research hotspots,including thirdwave cognitive behavior therapy,short-term psychoanalytic psychotherapy,cognitive behavioral analysis system of psychotherapy,family element in psychotherapy,modular treatment,mobile-health,emotion-regulation-based transdiagnostic intervention program,dementia risk in later life,predictors of the efficacy of psychological intervention,and risks of psychological intervention.CONCLUSION This bibliometric study provides a comprehensive overview of PIDCA from 2010 to present.Psychological intervention characterized as psychological-process-focused,short,family-involved,modular,internet-based,emotionregulation-based,and personalized may benefit more young people.

Study on psychological resilience and associated influencing factors in lung cancer patients with bone metastases

BACKGROUND Evaluating the psychological resilience of lung cancer(LC)patients helps understand their mental state and guides future treatment.However,there is limited research on the psychological resilience of LC patients with bone me-tastases.AIM To explore the psychological resilience of LC patients with bone metastases and identify factors that may influence psychological resilience.METHODS LC patients with bone metastases who met the inclusion criteria were screened from those admitted to the Third Affiliated Hospital of Wenzhou Medical University.The psychological scores of the enrolled patients were collected.They were then grouped based on the mean psychological score:Those with scores lower than the mean value were placed in the low-score group and those with scores equal to or greater than the mean value was placed in the high-score group.The baseline data(age,gender,education level,marital status,residence,monthly income,and religious beliefs),along with self-efficacy and medical coping mode scores,were compared.RESULTS This study included 142 LC patients with bone metastases admitted to our hospital from June 2022 to December 2023,with an average psychological resilience score of 63.24±9.96 points.After grouping,the low-score group consisted of 69 patients,including 42 males and 27 females,with an average age of 67.38±9.55 years.The high-score group consisted of 73 patients,including 49 males and 24 females,with a mean age of 61.97±5.00 years.χ2 analysis revealed significant differences between the two groups in education level(χ2=6.604,P=0.037),residence(χ2=12.950,P=0.002),monthly income(χ2=9.375,P=0.009),and medical coping modes(χ2=19.150,P=0.000).Independent sample t-test showed that the high-score group had significantly higher self-efficacy scores(t=3.383,P=0.001)and lower age than the low-score group(t=4.256,P<0.001).Furthermore,multivariate logistic regression hazard analysis confirmed that self-efficacy is an independent protective factor for psychological resilience[odds ratio(OR)=0.926,P=0.035,95%confidence interval(CI):0.862-0.995],while age(OR=1.099,P=0.003,95%CI:1.034-1.169)and medical coping modes(avoidance vs confrontation:OR=3.767,P=0.012,95%CI:1.342-10.570;resignation vs confrontation:OR=5.687,P=0.001,95%CI:1.974-16.385)were identified as independent risk factors.A predictive model based on self-efficacy,age,and medical coping modes was developed.The receiver operating characteristic analysis showed an area under the curve value of 0.778(95%CI:0.701-0.856,P<0.001),indicating that the model has good predictive performance.CONCLUSION LC patients with bone metastases are less psychologically resilient than the general population.Factors such as self-efficacy,age,and medical coping modes influence their psychological resilience.Patients with low self-efficacy,old age,and avoidance/resignation coping modes should be closely observed.

Association between Meeting 24-Hour Movement Guidelines and Psychological Features of Chinese Emerging Adults

Background:Emerging adulthood is a pivotal life stage,presenting significant psychological and social changes,such as decreased sociability,depression,and other mental health problems.Previous studies have associated these changes with an unhealthy lifestyle.The 24-h movement guidelines for healthy lifestyles have been developed to promote appropriate health behaviors and improve individual wellness.However,the relationship between adherence to the 24-h movement guidelines and different characteristics of Chinese emerging adults is yet to be explored.This cross-sectional study aimed to investigate the association between adherence to the 24-h movement guidelines and four characteristics(self-exploration,instability,possibilities,and responsibility)of Chinese emerging adults.Methods:Overall,1,510 Chinese emerging adults aged 18–29 years were included in this study.Each participant completed a self-administered questionnaire that included questions on adherence to the 24-h movement guidelines(physical activity,sedentary behavior,and sleep)and the inventory of dimensions of emerging adulthood.Multivariable logistic regression analysis was employed to investigate the associations between adherence to the 24-h movement guidelines and each of the four characteristics.Results:The proportion of participants who adhered to the 24-h movement guidelines was 31.72%.Multiple regression analysis revealed a significantly negative relationship between adhering to more guidelines and instability(β=−0.51,p<0.001).A statistically significant association was observed between instability and meeting only sedentary behavior(β=−1.27,95%confidence interval[CI]:[−2.32,−0.24],p=0.02),sedentary behavior+sleep(β=−1.30,95%CI:[−2.24,−0.35],p<0.01),and physical activity+sedentary behavior(β=−1.08,95%CI:[1.94,−0.21],p=0.02)guidelines.Further,positive and significant associations were observed between possibilities and meeting the guidelines for only physical activity(β=0.70,95%CI:[0.14,1.27),p=0.01),only sleep(β=0.61,95%CI:[0.01,1.21],p=0.04),physical activity+sedentary behavior(β=0.56,95%CI:[0.04,1.07),p=0.01),and physical activity+sleep(β=0.76,95%CI:[0.23,1.27],p=0.01).Conclusions:These findings suggest that adherence to the 24-h movement guidelines was associated with instability in Chinese emerging adults.Future studies are warranted to verify our findings to highlight the importance of maintaining a heath lifestyle to promote health in emerging adulthood.

Breast cancer(BC)is the most common malignant tumor in women,and the treatment process not only results in physical pain but also significant psychological distress in patients.Psychological intervention(PI)has been recognized as an important approach in treating postoperative psychological disorders in BC patients.It has been proven that PI has a significant therapeutic effect on postoperative psychological disorders,improving patients'negative emotions,enhancing their psychological resilience,and effectively enhancing their quality of life and treatment compliance.

Effects of intensive psychological intervention on treatment compliance,psychological status,and quality of life of patients with epilepsy

BACKGROUND Epilepsy is a nervous system disease characterized by recurrent attacks,a long disease course,and an unfavorable prognosis.It is associated with an enduring therapeutic process,and finding a cure has been difficult.Patients with epilepsy are predisposed to adverse moods,such as resistance,anxiety,nervousness,and anxiety,which compromise treatment compliance and overall efficacy.AIM To explored the influence of intensive psychological intervention on treatment compliance,psychological status,and quality of life(QOL)of patients with epilepsy.METHODS The clinical data of 105 patients with epilepsy admitted between December 2019 and July 2023 were retrospectively analyzed,including those of 50 patients who underwent routine intervention(control group)and 55 who underwent intensive psychological intervention(research group).Treatment compliance,psychological status based on the Self-Rating Anxiety Scale(SAS)and Depression Scale Self-Rating Depression Scale(SDS)scores,hope level assessed using the Herth Hope Scale(HHS),psychological resilience evaluated using the Psychological Resilience Scale,and QOL determined using the QOL in Epilepsy-31 Inventory(QOLIE-31)were comparatively analyzed.RESULTS Treatment compliance in the research group was 85.5%,which is significantly better than the 68.0%of the control group.No notable intergroup differences in preinterventional SAS and SDS scores were identified(P>0.05);however,after the intervention,the SAS and SDS scores decreased significantly in the two groups,especially in the research group(P<0.05).The two groups also exhibited no significant differences in preinterventional HHS,Connor-Davidson Resilience Scale(CD-RISC),and QOLIE-31 scores(P>0.05).After 6 months of intervention,the research group showed evidently higher HHS,CD-RISC,tenacity,optimism,strength,and QOLIE-31 scores(P<0.05).CONCLUSION Intensive psychological intervention enhances treatment compliance,psychological status,and QOL of patients with epilepsy.

A systematic scoping review of study methodology for randomized controlled trials investigating probiotics in athletic and physically active populations

Background:The purported ergogenic and health effects of probiotics have been a topic of great intrigue among researchers,practitioners,and the lay public alike.There has also been an increased research focus within the realm of sports science and exercise medicine on the athletic gut microbiota.However,compared to other ergogenic aids and dietary supplements,probiotics present unique study challenges.The objectives of this systematic scoping review were to identify and characterize study methodologies of randomized controlled trials investigating supplementation with probiotics in athletes and physically active individuals.Methods:Four databases(MEDLINE,CINAHL,Cochrane CENTRAL,and Cochrane Database of Systematic Reviews)were searched for randomized controlled studies involving healthy athletes or physically active individuals.An intervention with probiotics and inclusion of a control and/or placebo group were essential.Only peer-reviewed articles in English were considered,and there were no date restrictions.Results were extracted and presented in tabular form to detail study protocols,characteristics,and outcomes.Bias in randomized controlled trials was determined with the RoB 2.0 tool.Results:A total of 45 studies were included in the review,with 35 using a parallel group design and 10 using a cross-over design.Approximately half the studies used a single probiotic and the other half a multi-strain preparation.The probiotic dose ranged from 2×10^(8)to 1×10^(11)colony forming units daily,and the length of intervention was between 7 and 150 days.Fewer than half the studies directly assessed gastrointestinal symptoms,gut permeability,or the gut microbiota.The sex ratio of participants was heavily weighted toward males,and only 3 studies exclusively investigated females.Low-level adverse events were reported in only 2 studies,although the methodology of reporting varied widely.The risk of bias was generally low,although details on randomization were lacking in some studies.Conclusion:There is a substantial body of research on the effects of prob iotic supplementation in healthy athletes and physically active individuals.Considerable heterogeneity in probiotic selection and dosage as well as outcome measures has made clinical and mechanistic interpretation challenging for both health care practitioners and researchers.Attention to issues of randomization of participants,treatments and interventions,selection of outcomes,demographics,and reporting of adverse events will facilitate more trustworthy interpretation of probiotic study results and inform evidence-based guidelines.

Enhancing wood efficiency through comprehensive wood flow analysis:Methodology and strategic insights

Wood,an essential natural resource in human civilization,remains widely used despite advances in technology and material substitution.The surge in greenhouse gas emissions and environmental concerns accentuates the need for optimizing wood utilization.Material flow analysis is a powerful tool for tracking material flows and stocks,aiding resource management and environmental decision-making.However,the full extent of its methodological dimensions,particularly within the context of the wood supply chain,remains relatively unexplored.In this study,we delve into the existing literature on wood flow analysis,discussing its primary objectives,materials involved,temporal and spatial scales,data sources,units,and conversion factors.Additionally,data uncertainty,data reconciliation and crucial assumptions in material flow analysis are highlighted in this paper.Key findings reveal the significance of wood cascading and substitution effects by replacing non-wood materials,where they can reduce greenhouse gas emissions more than the natural carbon sink of forests and wood products.The immediate impact of short-term wood cascading might not be as robust as the substitution effect,with energy substitution showcasing better results than material substitution.However,it's crucial to note that these conclusions could experience significant reversal from a long-term and global perspective.Strategies for improving wood efficiency involve maximizing material use,advancing construction technologies,extending product lifespans,promoting cascade use,and optimizing energy recovery processes.The study underscores the need for standardized approaches in wood flow analysis and emphasizes the potential of wood efficiency strategies in addressing environmental challenges.

Clinical Effect Observation of Constructing PERMA Model in Psychological Intervention for Patients with Chronic Cancer Pain

Background:The constructing PERMA model in psychological intervention was applied to patients with chronic cancer pain to provide data reference for reducing pain,fear of cancer recurrence,and improving the level of psychological capital.Aim:To explore the clinical effects of constructing PERMA model in psychological intervention for patients with chronic cancer pain.Methods:A total of 98 patients with chronic cancer pain admitted to our hospital from March 2021 to March 2023 were randomly divided into two groups,49 cases in each group.The control group received routine intervention,while the research group constructed PERMA model based on the routine intervention for psychological intervention.The pain severity,fear of cancer recurrence,psychological capital and quality of life before and after intervention were compared between the two groups.Results:After two months of intervention,the pain in the research group was milder than that in the control group(p<0.05).The scores and total scores of all dimensions of fear of cancer recurrence in the research group were lower than those in the control group(p<0.05).The scores and total scores of each dimension of psychological capital in the research group were higher than those in the control group(p<0.05).The scores of all dimensions of quality of life in the research group were higher than those in the control group(p<0.05).Conclusion:The PERMA model constructed in psychological interventions for patients with chronic cancer pain can assist analgesic medications to reduce pain and alleviate the fear of cancer recurrence,increase the level of psychological capital,and thus improve quality of life.

Correlation between blepharospasm and psychological diseases:the anxiety,depression and sleep disorder study

AIM:To investigate the relationship between benign essential blepharospasm(BEB)symptoms and depression/anxiety/sleep disorder in a prospective manner and to determine whether treatment the BEB with botulinum toxin type A(BoNT/A)can impact psychological symptoms.METHODS:This prospective interventional case series recruited 61 adults with evidence of BEB.Patients were administered the Jankovic Rating Scale(JRS),the Blepharospasm Disability Index(BSDI),Personal Health Questionnaire Depression Scale(PHQ-8),Generalized Anxiety Disorder 7-item scale(GAD-7)and the Athens insomnia scale(AIS)to evaluate the severity of BEB symptoms,depression,anxiety and sleep disorder before and 1wk,1,3mo after the BoNTA treatment.Statistical analysis was performed to assess the relationships between changes in the survey scores.RESULTS:The mean score for JRS,BSDI,PHQ-8,and GAD-7 improved significantly(P<0.0001),respectively,compared to the initial visit at follow-up.At baseline,worse BSDI scores were correlated with worse GAD-7 and PHQ-8,but not with worse AIS.At 1mo follow-up visit,there was no correlation between change in BSDI and PHQ-8/AIS,the change in GAD-7 showed a mild association with change in BSDI.The change in BSDI was correlated with the change in both PHQ-8 and GAD-7 in the subgroup of patients without a prior diagnosis of depression or anxiety.Patient satisfaction with BoNT/A treatment reached the highest at 1mo of follow-up(83.6%,51/61).CONCLUSION:BEB may lead to psychological diseases.BoNT/A can significantly improve motor and non-motor symptoms of BEB,which emphasize the effectiveness of BoNT/A and therefore pave the way for its use in the field of psychiatry.However,further research is needed to confirm these findings and understand the underlying mechanisms.

Psychological Distress amongst Healthcare Workers in Douala

Introduction: Psychological distress can affect every worker’s mental health or working ability, and specifically the healthcare workers. It is essential to prevent and treat it in order to anticipate predictable consequences. The aim of this study was to investigate the epidemiological characteristics of psychological distress among the healthcare workers in the city of Douala. Material and Methods: This cross-sectional study was carried out during the 1st semester of 2023 in two reference hospitals of the city of Douala. All volunteer staff from the targeted hospitals were involved. We collected data using a mixed questionnaire that included the working conditions, as of the socioprofessional and psychological characteristics of the healthcare workers. We measured the level of psychological distress using the Kessler scale. Analysis was performed using the Chi-2 test and multivariate analysis. Threshold value was & = 5%, p Results: The participation rate was 86.3%. Women (81.7%) and nurses (77.6%) predominated in the sample. The mean age was 35.38 ± 8.9 years, and individuals in their thirties accounted for 46.79% of the sample. The prevalence of psychological distress was 19.5%. The psychological distress was categorized as mild (48.72%), moderate (18.46%) or severe (32.82%). Risk factors for psychological distress included being of the catholic faith (OR = 3.6, p = 0.04), poor sleep quality (OR = 3.9, p = 0.001) and long working hours (OR = 2.2, p = 0.002). Overtime was the only protective factor identified (OR = 0.6, p = 0.04). Conclusion: Nearly 1 out of 5 healthcare workers suffered from psychological distress exacerbated by poor working and living conditions. There is an urgent need to improve their working conditions to prevent the development of more severe consequences.

How to use the Surveillance,Epidemiology,and End Results(SEER)data:research design and methodology

In the United States(US),the Surveillance,Epidemiology,and End Results(SEER)program is the only comprehensive source of population-based information that includes stage of cancer at the time of diagnosis and patient survival data.This program aims to provide a database about cancer incidence and survival for studies of surveillance and the development of analytical and methodological tools in the cancer field.Currently,the SEER program covers approximately half of the total cancer patients in the US.A growing number of clinical studies have applied the SEER database in various aspects.However,the intrinsic features of the SEER database,such as the huge data volume and complexity of data types,have hindered its application.In this review,we provided a systematic overview of the commonly used methodologies and study designs for retrospective epidemiological research in order to illustrate the application of the SEER database.Therefore,the goal of this review is to assist researchers in the selection of appropriate methods and study designs for enhancing the robustness and reliability of clinical studies by mining the SEER database.

Application of psychological intervention in intensive care unit nursing for patients with severe acute pancreatitis

BACKGROUND Severe acute pancreatitis(SAP)is a familiar critical disease in the intensive care unit(ICU)patients.Nursing staff are important spiritual pillars during the treatment of patients,and in addition to routine nursing,more attention needs be paid to the patient’s psychological changes.AIM To investigate the effects of psychological intervention in ICU patients with SAP.METHODS One hundred ICU patients with SAP were hospitalized in the authors’hospital between 2020 and 2023 were selected,and divided into observation and control groups per the hospitalization order.The control and observation groups received routine nursing and psychological interventions,respectively.Two groups are being compared,using the Self-rating Anxiety Scale(SAS),Self-Determination Scale(SDS),Acute Physiology and Chronic Health Evaluation(APACHE)Ⅱ,and 36-item Short Form Health Survey(SF-36)scores;nursing satisfaction of patients;ICU care duration;length of stay;hospitalization expenses;and the incidence of complications.RESULTS After nursing,the SDS,SAS,and APACHEⅡ scores in the experimental group were significantly lower than in the control group(P<0.05).The SF-36 scores in the observation group were significantly higher than those in the control group(P<0.05).The nursing satisfaction of patients in the experimental group was 94.5%,considerably higher than that of 75.6% in the control group(P<0.05).The ICU care duration,length of stay,and hospitalization expenses in the observation group were significantly lower than those in the control group,and the incidence of complications was lower(P<0.05).CONCLUSION For patients with SAP,the implementation of standardized psychological intervention measures can effectively alleviate adverse psychological conditions.

Optimization and Characterization of Cellulose Extraction from Grevillea robusta (Silky Oak) Leaves by Soda-Anthraquinone Pulping Using Response Surface Methodology

Response surface methodology (RSM) using the central composite design (CCD) was applied to examine the impact of soda-anthraquinone pulping conditions on Grevillea robusta fall leaves. The pulping factors studied were: NaOH charge 5% to 20% w/v, pulping time 30 to 180 minutes, and the anthraquinone charge 0.1 to 0.5% w/w based on the oven-dried leaves. The responses evaluated were the pulp yield, cellulose content, and the degree of delignification. Various regression models were used to evaluate the effects of varying the pulping conditions. The optimum conditions attained were;NaOH charge of 14.63%, 0.1% anthraquinone, and a pulping period of 154 minutes, corresponding to 20.68% pulp yield, 80.56% cellulose content, and 70.34% lignin removal. Analysis of variance (ANOVA), was used to determine the most important variables that improve the extraction process of cellulose. The experiment outcomes matched those predicted by the model (Predicted R2 = 0.9980, Adjusted R2 = 0.9994), demonstrating the adequacy of the model used. FTIR analysis confirmed the elimination of the non-cellulosic fiber constituents. The lignin and hemicellulose-related bands (around 1514 cm−1, 1604 cm−1, 1239 cm−1, and 1734 cm−1) decreased with chemical treatment, indicating effective cellulose extraction by the soda-anthraquinone method. Similar results were obtained by XRD, SEM and thermogravimetric analysis of the extracted cellulose. Therefore, Grevillea robusta fall leaves are suitable renewable, cost-effective, and environmentally friendly non-wood biomass for cellulose extraction.

The Effect of Psychological Resilience on Hopelessness and Post-Traumatic Growth in Individuals Experienced by Earthquake

Background:Disasters have effects that leave great negative marks on our lives,even after many years have passed.Individuals who experience an earthquake experience physical and psychological difficulties.The purpose of this study is to determine how psychological resilience levels affect the feeling of hopelessness and post-traumatic growth in adults who experienced the 06 February,2023 Turkey-Syria earthquake.Methods:Data were collected using the“Personal Information Form(PIF)”,“Turkish forms of Adult Resilience Measure(ARM)”,“Dispositional Hope Scale(DHS)”and“Post-Traumatic Growth Inventory(PTGI)”.In order to determine whether there is a significant difference in the effect of psychological resilience of earthquake victims participating in the study on hope and post-traumatic growth levels in terms of socio-demographic variables,after determining that the data was normally distributed,total score average,minimum and maximum values,standard deviation(SD),independent sample t-test,ANOVA,correlation analysis to determine the relationship between the scales and multiple regression analysis to determine the effect between the scales were performed.Results:Of the 202 earthquake victims who participated in the study,65.8%were between the ages of 18–34,67.3%were female,92.1%were not trapped under the rubble,and 34.2%had second-degree relatives trapped under the rubble.It was determined that 77.8%of them lost their relatives in the earthquake and 77.8%of them lost a serious amount of property and money due to the earthquake.As a result of the analysis,it was determined that psychological resilience had a statistically significant and positive effect on hopelessness and post-traumatic growth in individuals who experienced the 06 February earthquake.In this regard,it has been determined that as the psychological resilience of individuals increases,their hope levels and post-traumatic growth will also increase.Conclusion:Based on the research results,increasing hope and increasing psychological resilience in psychosocial support studies carried out by mental health professionals for traumatic events will contribute to the spiritual recovery of individuals.
