However, studies have revealed instances where nurses demonstrate inaccurate practices. This study is aimed to measure the physical assessment skills of critical care nurses and the differences between levels of nursing education. Methods: A descriptive cross-sectional study was conducted involving a simple random sample of 101 nurses employed in critical care units. Results: Of the 101 participants, 56.4% were identified as female and 43.6% were male. In the sample, 71.0% held a diploma in nursing, while 29.0% held a Bachelor of Science in Nursing (BSN). Vital signs, orientation, and skin assessments were performed correctly in ≥90% of cases, whereas the majority (≥60%) did not correctly assess neck veins, Homan’s signs, breath sounds, heart sounds, and bowel sounds. Only ≤10% of participants accurately executed these assessments. Significant associations were found between sex and pain (P=0.034), as well as between the type of education and closure of the health assessment (P=0.041). Further, female nurses scored 10.0 ± 2.3, and male nurses 8.5 ± 2.5, diploma holders scored 9.4 ± 1.8, and BSN holders scored 9.3 ± 2.7 at the global rating. Conclusions: The presence of an existing gap in the accurate assessment of patients poses a potential risk to patient care. It is essential to investigate the factors contributing to this gap and to develop strategies to address it, thereby enhancing the quality of physical assessment and ultimately improving patient care.展开更多

Unhealthy eating habits and lack of proper nutrition knowledge cause non-communicable diseases and affect adolescents. It is in adolescence that eating habits are formed that persist till adulthood. Lifestyle interventions are needed to curb NCDs in adolescents. This paper reports the findings of a study that aimed to validate a lifestyle intervention program and its effect on food intake, physical activity, and nutrition knowledge. It was a clustered randomized control trial study conducted in four (4) junior secondary schools. There were 46 participants, 21 in the control and 25 in the intervention arm, who were blindly assigned to each arm by a statistician. Information and skills on nutrition were imparted using the Information, Motivation, and Behavioral Skills model. The program was implemented for eight (8) weeks hourly after school. A questionnaire was used to collect data pre- and post-intervention. Number, proportion, percentage, and independent t-test (mean and SD or median and IQR, p-value) were calculated using numerical and categorical data. The findings showed that the lifestyle intervention was valid, and there was a slight decrease in the intake of sweets among participants in both trial arms (p = 0.066). There was no significant difference in terms of food intake. Only a small number of participants still ate a few fruits, and there was no change in vegetable intake in both trial arms (p = 0.641). There was no change in the intake of fried foods in both trail arms (p = 0.402). Regarding nutrition knowledge, there was a slight significant difference of p = 0.079 between the trial arms. Though the effect of the lifestyle intervention program was not statistically significant, the results are promising, especially if the duration could be increased to a longer period and a larger sample size included.展开更多

We prove that circuit complexity satisfies all requirements for physical observables, including self-adjointness, gauge invariance, and a consistent measurement theory with well-defined uncertainty relations. We develop complete protocols for measuring complexity in quantum systems and demonstrate its connections to gauge theory and quantum gravity. Our results suggest that computational requirements may constitute physical laws as fundamental as energy conservation. This framework grants insights into the relationship between quantum information, gravity, and the emergence of spacetime geometry while offering practical methods for experimental verification. Our results indicate that the physical universe may be governed by both energetic and computational constraints, with profound implications for our understanding of fundamental physics.展开更多

However, the current generative adversarial networks applied in industrial processes do not impose realistic physical constraints on the generation of data, resulting in the generation of data that do not have realistic physical consistency. To address this problem, this paper proposes a physical consistency-based WGAN, designs a loss function containing physical constraints for industrial processes, and validates the effectiveness of the method using a common dataset in the field of industrial process fault diagnosis. The experimental results show that the proposed method not only makes the generated data consistent with the physical constraints of the industrial process, but also has better fault diagnosis performance than the existing GAN-based methods.展开更多

文摘Background:Taking actions to maintain a healthy lifestyle,including regular engagement in physical activity(PA)and reducing sedentary behavior(SB),may protect against the development of internalizing problems among healthy youth.However,it remains unclear whether such associations exist among youth with chronic pain who often report symptoms of depression and anxiety.To this end,we aimed to investigate the associations between independent and combined PA and/or SB patterns with indicators of internalizing problems in this vulnerable population.Methods:Data used in this cross-sectional study were retrieved from the U.S.National Survey of Children’s Health for the years 2021-2022.Specifically,caregiver proxy reports on sociodemgraphic factors and lifestyle behaviors of 4735 U.S.children and adolescents(referring to youth)aged 6-17 years were collected.We examined independent and combined patterns of PA and SB as exposures,with internalizing problems serving as outcomes of interest.Logistic regressions were used to examine the independent and combined associations of PA and/or SB patterns with anxiety and depression symptoms among youth with chronic pain while adjusting for covariates including age,sex,ethnicity,primary caregivers’education level,overweight status,and household federal poverty level.Results:Overall,our results indicated that PA was negatively associated with anxiety and depressive symptoms.Specifically,youth with chronic pain who engaged in at least 60-minute PA for 1-3 days,4-6 days,or every day reported significantly lower likelihood of experiencing symptoms of anxiety(OR=0.71,95%CI:0.60-0.84;OR=0.44,95%CI:0.36-0.53;OR=0.50,95%CI:0.40-0.63,respectively;all p-value<0.001)and depression(OR=0.63,95%CI:0.53-0.75;OR=0.38,95%CI:0.31-0.47;OR=0.46,95%CI:0.36-0.59,respectively;all p-value<0.001)symptoms compared to those with 0 days.Conversely,SB(operationalized via the proxy screen time)was positively associated with anxiety and depression symptoms.Youth with chronic pain who reported 4 or more hours of daily screen time had significantly higher odds of experiencing symptoms of anxiety(OR=2.17,95%CI:1.52-3.09,p<0.001)and depression(OR=2.30,95%CI:1.48-3.59,p<0.001).Furthermore,youth with chronic pain who engaged in higher PA levels and reported lower SB levels had a lower likelihood of experiencing symptoms of anxiety(OR=0.68,95%CI:0.52-0.87,p=0.003)and depression(OR=0.49,95%CI:0.34-0.70,p<0.001)symptoms compared to those with lower PA levels and higher SB levels.Conclusions:Higher PA levels and lower SB levels were associated with a reduced likelihood of developing anxiety and depression symptoms,which are indicative of internalizing problems,among youth with chronic pain.Future public health actions in this vulnerable population should prioritize intervention programs that promote PA engagement to reduce SB levels.
文摘Early intervention for sensorineural hearing loss(SNHL)in childhood is crucial for auditory and language development.In recent years,innovative auditory stimulation techniques and speech therapy strategies,such as middle ear implants,cochlear implants,auditory brainstem implants,and midbrain implants,have provided new avenues for improving patient outcomes.Additionally,basic research advancements in cell reprogramming and regeneration,stem cell therapy,and targeted drug delivery offer promising approaches to meet the individualized needs of children with SNHL.However,many challenges and unresolved issues remain in the treatment of SNHL.This article comments on the case report,which describes a female pediatric patient with SNHL who underwent foot reflexology which led to the normalization of hearing thresholds.Reflexology is considered to have potential benefits in physical rehabilitation,but its efficacy in hearing restoration requires further scientific validation through rigorous clinical trials and large-scale prospective studies.

文摘Alzheimer's disease is the primary cause of dementia and imposes a significant socioeconomic burden globally.Physical exercise,as an effective strategy for improving general health,has been largely reported for its effectiveness in slowing neurodegeneration and increasing brain functional plasticity,particularly in aging brains.However,the underlying mechanisms of exercise in cognitive aging remain largely unclear.Adiponectin,a cell-secreted protein hormone,has recently been found to regulate synaptic plasticity and mediate the antidepressant effects of physical exercise.Studies on the neuroprotective effects of adiponectin have revealed potential innovative treatments for Alzheimer's disease.Here,we reviewed the functions of adiponectin and its receptor in the brains of human and animal models of cognitive impairment.We summarized the role of adiponectin in Alzheimer's disease,focusing on its impact on energy metabolism,insulin resistance,and inflammation.We also discuss how exercise increases adiponectin secretion and its potential benefits for learning and memory.Finally,we highlight the latest research on chemical compounds that mimic exerciseenhanced secretion of adiponectin and its receptor in Alzheimer's disease.

文摘Background:The Teaching Personal and Social Responsibility(TPSR)model in physical education(PE)has been shown to promote Social and emotional competence(SEC).However,the underlying mechanisms through which TPSR enhances SEC,particularly in university students within the Chinese context,remain unclear.This study aims to explore the effects of TPSR and the mediating roles of self-efficacy and grit in improving SEC.Methods:71 Chinese university students were in the TPSR group,and 39 in the Traditional Teaching Model(TTM)control group,assessed before and after a 14-week intervention.The Adapted Social and Emotional Competence Scale(ASECS),General Self-Efficacy Scale(GSES),and Short Grit Scale(SGS)were used for measurement.A mixed-design ANOVA assessed TPSR’s effects,with post-hoc t-tests for pre-post differences and mediation analysis for underlying mechanisms.Results:The mixed-design ANOVA revealed a significant interaction between time and intervention on SEC.The TPSR group showed significant improvement from pre-test to post-test(t(70)=−2.63,p=0.011,Cohen’s d=−0.31),whereas the TTM control group did not(t(38)=1.40,p=0.170,Cohen’s d=0.22).The TPSR group also showed a significant increase in self-efficacy(t(70)=−3.67,p<0.001,Cohen’s d=−0.44),while no change was observed in the TTM group(t(38)=0.62,p=0.540,Cohen’s d=0.10).No significant effects were found for grit(F=0.342,p=0.560).Mediation analysis confirmed that self-efficacy significantly mediated the effects of the TPSR intervention on SEC(95%CI:0.0277 to 0.2897).Conclusion:The TPSR intervention led to significant improvements in university students’SEC and self-efficacy,with no significant changes observed in grit.Self-efficacy served as a mediator in the relationship between the intervention and SEC.
文摘Objective: Physical assessment is an indispensable and pivotal skill that nurses must aptly monitor, evaluate, and deliver timely care, particularly in the context of critically ill patients. However, studies have revealed instances where nurses demonstrate inaccurate practices. This study is aimed to measure the physical assessment skills of critical care nurses and the differences between levels of nursing education. Methods: A descriptive cross-sectional study was conducted involving a simple random sample of 101 nurses employed in critical care units. Results: Of the 101 participants, 56.4% were identified as female and 43.6% were male. In the sample, 71.0% held a diploma in nursing, while 29.0% held a Bachelor of Science in Nursing (BSN). Vital signs, orientation, and skin assessments were performed correctly in ≥90% of cases, whereas the majority (≥60%) did not correctly assess neck veins, Homan’s signs, breath sounds, heart sounds, and bowel sounds. Only ≤10% of participants accurately executed these assessments. Significant associations were found between sex and pain (P=0.034), as well as between the type of education and closure of the health assessment (P=0.041). Further, female nurses scored 10.0 ± 2.3, and male nurses 8.5 ± 2.5, diploma holders scored 9.4 ± 1.8, and BSN holders scored 9.3 ± 2.7 at the global rating. Conclusions: The presence of an existing gap in the accurate assessment of patients poses a potential risk to patient care. It is essential to investigate the factors contributing to this gap and to develop strategies to address it, thereby enhancing the quality of physical assessment and ultimately improving patient care.
文摘Non-communicable diseases (NCDs) are on the rise worldwide and in developing countries like Botswana. Unhealthy eating habits and lack of proper nutrition knowledge cause non-communicable diseases and affect adolescents. It is in adolescence that eating habits are formed that persist till adulthood. Lifestyle interventions are needed to curb NCDs in adolescents. This paper reports the findings of a study that aimed to validate a lifestyle intervention program and its effect on food intake, physical activity, and nutrition knowledge. It was a clustered randomized control trial study conducted in four (4) junior secondary schools. There were 46 participants, 21 in the control and 25 in the intervention arm, who were blindly assigned to each arm by a statistician. Information and skills on nutrition were imparted using the Information, Motivation, and Behavioral Skills model. The program was implemented for eight (8) weeks hourly after school. A questionnaire was used to collect data pre- and post-intervention. Number, proportion, percentage, and independent t-test (mean and SD or median and IQR, p-value) were calculated using numerical and categorical data. The findings showed that the lifestyle intervention was valid, and there was a slight decrease in the intake of sweets among participants in both trial arms (p = 0.066). There was no significant difference in terms of food intake. Only a small number of participants still ate a few fruits, and there was no change in vegetable intake in both trial arms (p = 0.641). There was no change in the intake of fried foods in both trail arms (p = 0.402). Regarding nutrition knowledge, there was a slight significant difference of p = 0.079 between the trial arms. Though the effect of the lifestyle intervention program was not statistically significant, the results are promising, especially if the duration could be increased to a longer period and a larger sample size included.

文摘Cancer-related fatigue(CRF)presents as a complex interplay between physical and mental fatigue,with mindfulness interventions offering a promising approach to alleviate both.These techniques,including mindfulness-based stress reduction,cognitive therapy,dialectical behavior therapy,and acceptance and commitment therapy,are designed to break the cycle of CRF by addressing its psychological and emotional aspects.This editorial integrates the latest research published by Liu et al,examining the reciprocal and harmful cyclical relationship between physical and mental CRF,and explores the causes and associated mindfulness interventions.We expect that future research will emphasize the identification and management of CRF,particularly focusing on the application of various mindfulness interventions in cancer survivors and patients undergoing cancer treatment,as well as the development of mindfulness in the era of new technologies.
文摘In our previous study,the activity and stability of the Mo/HZSM-5 catalyst were enhanced by mixing physically with NiO in methane dehydroaromatization(MDA)reaction.It has been confirmed that the physically mixed NiO not only promoted the dispersion of MoC_(x)active sites but also reduced the coke formation on the MoC_(x)owing to the CNTs growth on Ni.However,the promotional effect of NiO was limited when the particle size was reduced,due to the excessive interaction with MoOx(forming NiMoO_(4))which is detrimental to the MoC_(x)dispersion.In this study,to overcome the limitation,silica shell on NiO particles with various sizes(5,15,110 nm)was introduced.The catalyst with silica shell coated NiO with the size of 15 nm exhibited a significant improvement in both BTX yield and stability,and the catalyst with silica shell coated NiO with the size of 5 nm achieved the highest maximum BTX yield,about 7.2%.This study demonstrates that the catalytic performance improved as the NiO particle size decreased with the introduction of the silica shell.Combined transmission electron microscopy-energy dispersive spectroscopy,X-ray diffraction,temperature-programmed surface reaction of methane,CO chemisorption,visible Raman,and thermogravimetric analysis allowed us to confirm that a thin silica shell further enhances the MoC_(x)dispersion while preventing the formation of Ni-Mo complexes.However,when the size of NiO decreased to 5 nm,CNT growth on Ni was limited during the reaction,which is crucial for reducing coke formation on Mo active sites,thereby resulting in the decreased catalyst stabilization ability of Ni.Overall,this study indicates that the introduction of a silica shell in a controlled way can significantly enhance the promotional effect of physically mixed NiO on MDA.

文摘Physical exercise is recognized as an effective intervention to improve mood,physical performance,and general well-being.It achieves these benefits through cellular and molecular mechanisms that promote the release of neuroprotective factors.Interestingly,reduced levels of physical exercise have been implicated in several central nervous system diseases,including ocular disorders.Emerging evidence has suggested that physical exercise levels are significantly lower in individuals with ocular diseases such as glaucoma,age-related macular degeneration,retinitis pigmentosa,and diabetic retinopathy.Physical exercise may have a neuroprotective effect on the retina.Therefore,the association between reduced physical exercise and ocular diseases may involve a bidirectional causal relationship whereby visual impairment leads to reduced physical exercise and decreased exercise exacerbates the development of ocular disease.In this review,we summarize the evidence linking physical exercise to eye disease and identify potential mediators of physical exercise-induced retinal neuroprotection.Finally,we discuss future directions for preclinical and clinical research in exercise and eye health.
文摘This work proposes quantum circuit complexity—the minimal number of elementary operations needed to implement a quantum transformation—be established as a legitimate physical observable. We prove that circuit complexity satisfies all requirements for physical observables, including self-adjointness, gauge invariance, and a consistent measurement theory with well-defined uncertainty relations. We develop complete protocols for measuring complexity in quantum systems and demonstrate its connections to gauge theory and quantum gravity. Our results suggest that computational requirements may constitute physical laws as fundamental as energy conservation. This framework grants insights into the relationship between quantum information, gravity, and the emergence of spacetime geometry while offering practical methods for experimental verification. Our results indicate that the physical universe may be governed by both energetic and computational constraints, with profound implications for our understanding of fundamental physics.

文摘This study addresses the challenges posed by dispersive soil in various engineering fields,including hydraulic and agricultural engineering,by exploring the effects of physical adsorption on soil modification.The primary objective is to identify an environmentally friendly stabilizer that can alleviate cracking and erosion resulting from soil dispersivity.Activated carbon(AC),known for its porous nature,was examined for its potential to enhance soil strength and erosion resistance.The charge neutralization process was evaluated by monitoring pH and conductivity,in addition to a comprehensive analysis of microscopic and mineral properties.The results show that high sodium levels or low clay contents result in the dispersive nature of soil in water.However,the incorporation of AC can transform such soil into a non-dispersive state.Moreover,both soil strength and erosion resistance exhibited enhancements with increasing AC content and curing duration.The incorporation of AC resulted in a maximum 5.6-fold increase in unconfined compressive strength and a 1.8-fold increase in tensile strength for dispersive soil.Notably,a significant correlation was observed during the curing phase among soil dispersivity,mechanical properties,and pH values.Microscopic analyses revealed that the porous structure of AC facilitated a filling effect and enhanced adsorption capacity,which contributed to improved soil characteristics and reduced dispersivity.The release of hydrogen ions and the formation of aggregates promote water stability.Validation tests conducted on dispersive soil from northern Shaanxi demonstrated the efficacy of physical adsorption using AC as a viable method for modifying dispersive soil in the water conservancy hub.
文摘BACKGROUND While existing literature on ischiofemoral impingement syndrome(IFI)predominantly emphasizes surgical interventions or generalized physical therapy approaches,there remains a paucity of evidence regarding structured,multimodal rehabilitation programs targeting biomechanical deficits in IFI.This case report evaluates the efficacy of a multimodal rehabilitation program addressing a critical gap in conservative management strategies.CASE SUMMARY The patient underwent comprehensive physical and clinical examination,including hip X-ray and magnetic resonance imaging investigations.The patient completed the Musculoskeletal Health Questionnaire(MSK-HQ)and numerical pain rating scale(NPRS).The patient underwent a two-month tailored structured physical therapy intervention and repeated the same assessment afterwards.The patient's substantial reduction in pain,reflected by a significant decrease in the patient’s NPRS score from 9 to 3 points,signifies a positive clinical response.This outcome,coupled with the significant improvement in the patient's health-related quality of life according to the MSK-HQ score,which increased from 12 to 48 points,underscores the success of our research.CONCLUSION The study highlights the importance of a comprehensive approach to diagnosing and managing IFI,combining clinical assessment with imaging and implementing a multimodal rehabilitation program for optimal outcomes.
文摘Background:This study evaluated physical fitness and mental health in young and elderly women 3 months after mild COVID-19 infection,and examined the impact of infection and age on long COVID occurrence and trajectory.Methods:There were 213 eligible female volunteers(107 young,106 elderly)recruited approximately three months after the significant outbreak of COVID-19 in China.Participants completed a fitness test and mental health assessment using the Post-Traumatic Stress Disorder Self-Assessment Scale(PTSD)and the Pittsburgh Sleep Quality Inventory(PSQI).Results:Despite no significant difference in physical fitness,infected young and elderly females experienced poorer sleep quality related to mental health compared to their uninfected peers(+22%in young participants,p=0.027;+10%in elderly participants,p=0.005).The elderly scored significantly higher in sleep quality than the young(p<0.05).Age,previous infection,and PTSD were significant predictors of sleep quality,explaining 60.6%of the variance in PSQI scores.Conclusions:Three months following COVID-19 infection,infected women experienced poorer sleep quality compared to their uninfected peers.Irrespective of being infected,older individuals exhibited higher rates of sleep disorders compared to younger women,suggesting the importance of addressing postCOVID-19 sleep issues among at-risk individuals.
文摘Cyber-Physical Systems(CPS)represent an integration of computational and physical elements,revolutionizing industries by enabling real-time monitoring,control,and optimization.A complementary technology,Digital Twin(DT),acts as a virtual replica of physical assets or processes,facilitating better decision making through simulations and predictive analytics.CPS and DT underpin the evolution of Industry 4.0 by bridging the physical and digital domains.This survey explores their synergy,highlighting how DT enriches CPS with dynamic modeling,realtime data integration,and advanced simulation capabilities.The layered architecture of DTs within CPS is examined,showcasing the enabling technologies and tools vital for seamless integration.The study addresses key challenges in CPS modeling,such as concurrency and communication,and underscores the importance of DT in overcoming these obstacles.Applications in various sectors are analyzed,including smart manufacturing,healthcare,and urban planning,emphasizing the transformative potential of CPS-DT integration.In addition,the review identifies gaps in existing methodologies and proposes future research directions to develop comprehensive,scalable,and secure CPSDT systems.By synthesizing insights fromthe current literature and presenting a taxonomy of CPS and DT,this survey serves as a foundational reference for academics and practitioners.The findings stress the need for unified frameworks that align CPS and DT with emerging technologies,fostering innovation and efficiency in the digital transformation era.
文摘In real industrial scenarios, equipment cannot be operated in a faulty state for a long time, resulting in a very limited number of available fault samples, and the method of data augmentation using generative adversarial networks for smallsample data has achieved a wide range of applications. However, the current generative adversarial networks applied in industrial processes do not impose realistic physical constraints on the generation of data, resulting in the generation of data that do not have realistic physical consistency. To address this problem, this paper proposes a physical consistency-based WGAN, designs a loss function containing physical constraints for industrial processes, and validates the effectiveness of the method using a common dataset in the field of industrial process fault diagnosis. The experimental results show that the proposed method not only makes the generated data consistent with the physical constraints of the industrial process, but also has better fault diagnosis performance than the existing GAN-based methods.

文摘A complex geological environment with faults can be encountered in the process of coal mining.Fault activation can cause instantaneous structure slipping,releasing a significant amount of elastic strain energy during underground coal mining.This would trigger strong rockburst disasters.To understand the occurrence of fault-slip induced rockbursts,we developed a physical model test system for fault-slip induced rockbursts in coal mine drifts.The boundary energy storage(BES)loading apparatus and bottom rapid retraction(BRR)apparatus are designed to realize energy compensation and continuous boundary stress transfer of the surrounding rocks for instantaneous fault slip,as well as to provide space for the potential fault slip.Taking the typical fault-slip induced rockburst in the Xinjulong Coal Mine,China,as the background,we conducted a model test using the test system.The deformation and stress in the rock surrounding the drift and the support unit force during fault slip are analyzed.The deformation and failure characteristics and dynamic responses of drifts under fault-slip induced rockbursts are obtained.The test results illustrate the rationality and effectiveness of the test system.Finally,corresponding recommendations and prospects are proposed based on our findings.

文摘Background:Adolescents face increasing academic and social pressures,which significantly impact their mental well-being and coping strategies.Physical activity(PA)has been recognized as crucial in promoting psychological resilience and social development.This study investigates the relationship between PA and adolescents’coping styles,with a particular focus on the mediating roles of friendship quality and psychological resilience.By examining these associations,the study aims to provide insights into how PA contributes to adolescents’ability to navigate challenges and develop adaptive coping mechanisms.Methods:This study employed a cross-sectional design and was conducted in Suzhou,Jiangsu Province,China.A total of 2288 high school students aged 15–18 were recruited using a convenience sampling approach.Data were collected through validated self-report questionnaires measuring PA,friendship quality,psychological resilience,and coping styles.Pearson correlation analysis and structural equation modelling(SEM)were applied to examine the relationships between variables and assess the mediating effects of friendship quality and psychological resilience in the association between PA and coping styles.Results:Significant positive correlations among variables:PA positively correlated with friendship quality(r=0.29,p<0.01),psychological resilience(r=0.26,p<0.01),and coping styles(r=0.26,p<0.01).Friendship quality and psychological resilience mediated the relationship between PA and coping styles,with direct effects accounting for 47.85%of the total effect.Indirect effects were distributed among three pathways:via friendship quality(15.38%),psychological resilience(27.56%),and a chain mediation of both(11.22%).Conclusion:The findings highlight the significant role of PA in enhancing adolescents’coping styles,with friendship quality and psychological resilience as key mediators.These results underscore the importance of promoting PA to strengthen social bonds,build resilience,and improve adaptive coping mechanisms among adolescents.Future research should explore additional mediating factors and employ longitudinal or experimental designs to establish causal relationships.
文摘BACKGROUND Long-term chemotherapy for patients with gastric cancer(GC),facilitated by peripherally inserted central catheter(PICC)catheterization,reduces vascular damage and enhances drug delivery efficiency but carries risks of catheter-related complications.A combination of group psychological nursing and physical mo-vement care significantly mitigates the risk of venous thrombosis and improves psychological well-being,and enhances motor function,underscoring its clinical importance.AIM To assess group psychological and physical movement nursing in preventing venous thrombosis in patients with PICC GC.METHODS Sixty-five GC patients with PICC,admitted from January 2022 to January 2023,were randomly divided into two groups using the lottery method:A control group(n=35,routine nursing)and an observation group(n=30,routine nursing plus psychological nursing and physical movement nursing).Both groups re-ceived continuous care for 2 weeks.Pre-nursing and post-nursing data on psycho-logical state,physical function,chemotherapy-related thrombosis incidence,and cancer-related fatigue were analyzed using SPSS 26.0 and GraphPad Prism 8.0.RESULTS After nursing,both groups showed reduced Hamilton Anxiety Scale scores and increased General Perceived Self-Efficacy Scale scores,with the observation group performing better(P<0.05).The Functional Comprehensive Assessment score for the observation group after nursing was(65.42±2.35)points,lower than the control group’s(62.19±4.33)points(P<0.05).Although no significant difference was observed in the incidence of venous thrombosis between the two groups(χ2=0.815,P=0.367),the observation group had lower incidence.Both groups showed decreased Revised Piper Fatigue Scale scores,with the observation group scoring lower(P<0.05).CONCLUSION Group psychological and physical movement nursing for patients with PICC reduces venous thrombosis risk,improves psychological well-being,cancer-related fatigue,and physical function,making it highly promotable.
