This manuscript purposed to convince stockholders and policymakers of the negative impact of physical restraint on patients' psychological and physical health. The current authors review the ethical and legal underpinnings of the opponents' and proponents' views. On one hand, there is a clear violation of the main principles of the code of ethics. Autonomy and justice;as the patients are tied against their will and without obtaining their consent, non-maleficent;as physical restraints are reported in many cases of physical and psychological traumas, thus many agencies prohibited the use of physical restraints as a safety method to be replaced with other deescalating techniques. On the other hand, physical restraints are a precious method in controlling aggressive behaviors and maintaining patients' safety, which is the selective beneficence in providing patient care. Also, most of the same agencies who prohibited the use of restraints, agreed the use of physical restraint as the last resor t.Summary statement What is already known about this topic?· Currently, physical restraint is used as the first accessible method to manage patients' behaviors, without considering the negative aura that surrounds the way of treatment. The usage of physical restraint has gone beyond the purpose of maintaining patient safety and managing aggressive behaviors to be a punishment method.· The Ethical and Legal context of using physical restraints is still vague and needs more clarification.What does this paper add?· This manuscript illustrates the Ethical and Legal points of view of the opponents and proponents of using physical restraints.· The current manuscript clearly justifies the authors' point of view to oppose physical restraints usage and how physical restraints violate the core principles of the code of ethics. In addition, it illustrates the legal agencies that suppor t/oppose the usage of physical restraint and the rationale beyond that position.· This manuscript provides alternatives to manage patients' aggressive behaviors and other ways to protect patients' safety as well as patient's dignity and code of ethics.The implications of this paper This argumentative essay provides an accessible, relevant exploration of public health policy, and its impact on nursing practice, mental health services, and patient health. Moreover, it provides a forum for mental health services to evaluate the current implications of physical restraints. The manuscript creates a paradigm for future studies and projects on physical restraints usage.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Background There is a lack of research examining the interplay between objectively measured physical activity volume and intensity with life expectancy.The purpose of the study was to investigate the interplay between objectively measured PA volume and intensity profiles with modeled life expectancy in women and men within the UK Biobank cohort study and interpret findings in relation to brisk walking.Methods Individuals from UK Biobank with wrist-worn accelerometer data were included.The average acceleration and intensity gradient were extracted to describe the physical activity volume and intensity profile.Mortality data were obtained from national registries.Adjusted life expectancies were estimated using parametric flexible survival models.Results 40,953(57.1%)women(median age=61.9 years)and 30,820(42.9%)men(63.1 years)were included.Over a median follow-up of 6.9 years,there were 1719(2.4%)deaths(733 in women;986 in men).At 60 years,life expectancy was progressively longer for higher physical activity volume and intensity profiles,reaching 95.6 years in women and 94.5 years in men at the 90th centile for both volume and intensity,corresponding to 3.4 additional years(95%confidence interval(95%CI):2.4-4.4)in women and 4.6 additional years(95%CI:3.6-5.6)in men compared to those at the 10th centiles.An additional 10-min or 30-min daily brisk walk was associated with 0.9(95%CI:0.5-1.3)and 1.4 years(95%CI:0.9-1.9)longer life expectancy,respectively,in inactive women;and 1.4 years(95%CI:1.0-1.8)and 2.5(95%CI:1.9-3.1)in inactive men.Conclusion Higher physical activity volumes were associated with longer life expectancy,with a higher physical activity intensity profile further adding to a longer life.Adding as little as a 10-min brisk walk to daily activity patterns may result in a meaningful benefit to life expectancy.

文摘The shear wave(S-wave)velocity is a critical rock elastic parameter in shale reservoirs,especially for evaluating shale fracability.To effectively supplement S-wave velocity under the condition of no actual measurement data,this paper proposes a physically-data driven method for the S-wave velocity prediction in shale reservoirs based on the class activation mapping(CAM)technique combined with a physically constrained two-dimensional Convolutional Neural Network(2D-CNN).High-sensitivity log curves related to S-wave velocity are selected as the basis from the data sensitivity analysis.Then,we establish a petrophysical model of complex multi-mineral components based on the petrophysical properties of porous medium and the Biot-Gassmann equation.This model can help reduce the dispersion effect and constrain the 2D-CNN.In deep learning,the 2D-CNN model is optimized using the Adam,and the class activation maps(CAMs)are obtained by replacing the fully connected layer with the global average pooling(GAP)layer,resulting in explainable results.The model is then applied to wells A,B1,and B2 in the southern Songliao Basin,China and compared with the unconstrained model and the petrophysical model.The results show higher prediction accuracy and generalization ability,as evidenced by correlation coefficients and relative errors of 0.98 and 2.14%,0.97 and 2.35%,0.96 and 2.89%in the three test wells,respectively.Finally,we present the defined C-factor as a means of evaluating the extent of concern regarding CAMs in regression problems.When the results of the petrophysical model are added to the 2D feature maps,the C-factor values are significantly increased,indicating that the focus of 2D-CNN can be significantly enhanced by incorporating the petrophysical model,thereby imposing physical constraints on the 2D-CNN.In addition,we establish the SHAP model,and the results of the petrophysical model have the highest average SHAP values across the three test wells.This helps to assist in proving the importance of constraints.
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 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.
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Infections associated with titanium(Ti)-based implants present significant challenges in clinical treatments,especially when biofilms already form on the implant surface.Many antimicrobial agents,including antibiotics,metallic nanoparticles and antimicrobial peptides,have been extensively used to deal with Ti implant infections.However,these chemical approaches suffer from potential toxicity,antibiotic resistance and poor long-term antibacterial performance.Hence,physical antibacterial surfaces on Ti-based implants have attracted increasing attention.The antibacterial behavior of different surfaces on Ti-based biomaterials against various bacteria only by physical properties of the implants themselves(e.g.,nanotopography)or exogenous physical stimulus(e.g.,photocatalysis)was reviewed,as well as parameters influencing the physical antibacterial processes,such as size,shape and density of the surface nanotextures,and bacterial growth phases.Besides,mechanisms of different fabrication techniques for the physical antibacterial surfaces on Ti-based biomaterials were also summarized.
文摘Physical restraint is one of the most controversial methods in managing aggressive behaviors and maintaining patients' safety. This manuscript purposed to convince stockholders and policymakers of the negative impact of physical restraint on patients' psychological and physical health. The current authors review the ethical and legal underpinnings of the opponents' and proponents' views. On one hand, there is a clear violation of the main principles of the code of ethics. Autonomy and justice;as the patients are tied against their will and without obtaining their consent, non-maleficent;as physical restraints are reported in many cases of physical and psychological traumas, thus many agencies prohibited the use of physical restraints as a safety method to be replaced with other deescalating techniques. On the other hand, physical restraints are a precious method in controlling aggressive behaviors and maintaining patients' safety, which is the selective beneficence in providing patient care. Also, most of the same agencies who prohibited the use of restraints, agreed the use of physical restraint as the last resor t.Summary statement What is already known about this topic?· Currently, physical restraint is used as the first accessible method to manage patients' behaviors, without considering the negative aura that surrounds the way of treatment. The usage of physical restraint has gone beyond the purpose of maintaining patient safety and managing aggressive behaviors to be a punishment method.· The Ethical and Legal context of using physical restraints is still vague and needs more clarification.What does this paper add?· This manuscript illustrates the Ethical and Legal points of view of the opponents and proponents of using physical restraints.· The current manuscript clearly justifies the authors' point of view to oppose physical restraints usage and how physical restraints violate the core principles of the code of ethics. In addition, it illustrates the legal agencies that suppor t/oppose the usage of physical restraint and the rationale beyond that position.· This manuscript provides alternatives to manage patients' aggressive behaviors and other ways to protect patients' safety as well as patient's dignity and code of ethics.The implications of this paper This argumentative essay provides an accessible, relevant exploration of public health policy, and its impact on nursing practice, mental health services, and patient health. Moreover, it provides a forum for mental health services to evaluate the current implications of physical restraints. The manuscript creates a paradigm for future studies and projects on physical restraints usage.

文摘Background:A shift from self-reports to wearable sensors for global physical activity(PA)surveillance has been recommended.The conventional use of a generic cut-point to assess moderate-to-vigorous PA(MVPA)is problematic as these cut-points are often derived from non-representative samples under non-ecological laboratory conditions.This study aimed to develop age-and sex-(age-sex)specific cut-points for MVPA based on population-standardized values as a feasible approach to assess the adherence to PA guidelines and to investigate its associations with all-cause mortality.Methods:A total of 7601 participants(20-85+years)were drawn from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Surveys(NHANES).Minutes per week of MVPA were assessed with a hip-worn accelerometer.Counts per minute(CPM)were used to define an age-sex specific target intensity,representing the intensity each person should be able to reach based on their age and sex.Age-sex specific MVPA cut-points were defined as any activity above 40%of the target intensity.These population-and free-living-based age-sex specific cut-points overcome many of the limitations of the standard generic cut-point approach.For comparison,we also calculated MVPA with a generic cut-point of 1952 CPM.Both approaches were compared for assessing adherence to PA guidelines and association of MVPA with allcause mortality(ascertained through December 2015).Results:Both approaches indicated that 37%of the sample met the 150+min/week guideline.The generic cut-point approach showed a trend to inactivity with age,which was less pronounced using the age-sex specific cut-points.Overall mortality rates were comparable using generic cutpoint(hazard ratio(HR)=0.61,95%confidence interval(95%CI):0.50-0.73)or age-sex specific cut-points(HR=0.57,95%CI:0.50-0.66)for the entire sample.The generic cut-point method revealed an age-and sex-related gap in the benefits of achieving 150+min/week of MVPA,with older adults showing an 18%greater reduction in mortality rates than younger adults,and a larger difference in women than in men.This disparity disappeared when using age-sex specific cut-points.Conclusion:Our findings underscore the value of age-sex specific cut-points for global PA surveillance.MVPA defined with age-sex specific thresholds was associated with all-cause mortality and the dose-response was similar for all ages and sexes.This aligns with the single recommendation of accumulating 150+min/week MVPA for all adults,irrespective of age and sex.This study serves as a proof of concept to develop this methodology for PA surveillance over more advanced open-source acceleration metrics and other national and international cohorts.
