Impact of Action Observation Therapy along with Usual Physiotherapy Intervention of Individual with Alzheimer’s Disease

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by cognitive impairments in the initial stage, which lead to severe cognitive dysfunction in the later stage. Action observation therapy (AOT) is a multisensory cognitive rehabilitation technique where the patient initially observes the actions and then tries to perform. The study aimed to examine the impact of AOT along with usual physiotherapy interventions to reduce depression, improve cognition and balance of a patient with AD. A 67 years old patient with AD was selected for this study because the patient has been suffering from depression, dementia, and physical dysfunction along with some other health conditions like diabetes and hypertension. Before starting intervention, a baseline assessment was done through the Beck Depression Inventory (BDI) tool, the Mini-Cog Scale, and the Berg Balance Scale (BBS). The patient received 12 sessions of AOT along with usual physiotherapy interventions thrice a week for four weeks, which included 45 minutes of each session. After four weeks of intervention, the patient demonstrated significant improvement in depression, cognition, and balance, whereas the BDI score declined from moderate 21/63 to mild 15/63 level of depression. The Mini-Cog score improved from 2/5 to 4/5, and the BBS score increased from 18/56 to 37/56. It is concluded that AOT along with usual physiotherapy intervention helps to reduce depression, improve cognition and balance of people with AD.

The Impact and Intervention of Handheld Tai Chi Water-Resistance Fitness Ball on Middle-Aged and Elderly Patients with Parkinson’s Disease

Through the use of a survey and statistical methods, this study explores the effects and interventions of handheld Tai Chi water resistance fitness balls on the elderly with Parkinson’s disease. Firstly, a questionnaire on exercise compliance for patients with Parkinson’s disease was developed, and its reliability and validity were tested. Then, a survey was conducted to investigate the current status of exercise compliance among Parkinson’s disease patients, including general information, scoring status, and single and multiple factor analyses of influencing factors [1]. The results of the study show that through qualitative research, the dimensions and item pools of the questionnaire were initially constructed, and the reliability analysis of the questionnaire was conducted through Delphi expert consultation, with favorable results in terms of its reliability and validity [2]. Regarding the current status of exercise compliance among Parkinson’s disease patients, the study found that the level of exercise compliance needs improvement, and there are significant differences in exercise compliance levels among patients under different circumstances. Finally, the research results were discussed and conclusions were drawn. The innovation of this study lies in the development of a questionnaire on exercise compliance for patients with Parkinson’s disease and the preliminary qualitative research and Delphi expert consultation conducted on it, providing new ideas and methods for the study of exercise compliance. However, the study also has limitations as it did not examine the effects of other interventions on Parkinson’s disease, so further research should be conducted [3].

Group Psychological Intervention for Children with Hyperactivity Disorder

ADHD is a broad psychiatric disorder that affects children of normal or near-normal intelligence.It is character-ized by inattention,hyperactivity,and age-inappropriate impulsivity,and it is often accompanied by learning dif-ficulties,behavioral,emotional,and interpersonal problems.On the other hand,hyperactive tendencies in children with ADHD exhibit ADHD-like behaviors such as lack of self-control,inattention,hyperactivity,and emotional impulsivity.However,because their symptoms are less severe,they do not meet the diagnostic criteria for ADHD but are ADHD or at risk of developing ADHD.The purpose of this study is to alleviate and reduce children’s hyperactivity symptoms by investigating the current situation of the children studied,and systemati-cally intervening and educating children with ADHD through psychological group intervention.Research data shows that ADHD is most commonly diagnosed in school-age children,and in 70%–80%of children with ADHD,symptoms persist into adolescence and 30%into adulthood.Through the use of group psychological intervention in the experiment,the prevalence rate of children with hyperactivity disorder tendency has been effectively reduced.This shows that group psychological intervention training has a significant effect on improving hyper-activity symptoms in children with ADHD tendency.

Role of ferroptosis in Parkinson’s disease and intervention mechanism of acupuncture and moxibustion

Parkinson’s disease(PD)is the second neurodegenerative disease in the world.The pathological characteristics of PD are degeneration,loss and death of dopaminergic neurons in the substantia nigra of the midbrain.At present,most scholars believe that the main pathogenesis of PD is α-synuclein aggregation,oxidative stress,mitochondrial dysfunction and neuroinflammatory reaction.More and more studies have demonstrated that ferroptosis plays an important role in the occurrence and development of PD.Ferroptosis is a new type of cell death that is significantly different from traditional apoptosis,scorching and necrosis.Its main feature is iron-dependent lipid peroxidation.Some studies have found that the efficacy of acupuncture and moxibustion in the treatment of PD may be related to the regulation of ferroptosis.Therefore,this study mainly discusses the occurrence and development mechanism of ferroptosis and its role in PD,and the possible mechanism of acupuncture and moxibustion in the treatment of PD dopaminergic neurons,so as to provide theoretical basis for acupuncture and moxibustion in the treatment of PD.

Effect of nursing intervention based on Maslow's hierarchy of needs in patients with coronary heart disease interventional surgery

BACKGROUND It is very important to provide effective nursing programs to regulate the physical and mental state of patients and to improve treatment compliance after interventional surgery for coronary heart disease(CHD).AIM To explore the effect of a nursing intervention based on Maslow’s hierarchy of needs theory on patients with CHD undergoing percutaneous coronary intervention.METHODS Ninety-four patients with CHD undergoing interventional surgery in our hospital from January 2020 to February 2021 were randomly divided into a research group(n=47)and a control group(n=47).The control group received routine nursing,and the research group received a nursing intervention based on Maslow’s hierarchy of needs theory.The scores of self-efficacy,negative emotion[depression(SDS),anxiety(SAS)],intervention compliance(standardized medication,moderate exercise,healthy diet,and regular review),and nursing satisfaction were calculated before and after intervention for the two groups.RESULTS Before intervention,there was no significant difference in the scores of disease general management self-efficacy,disease management self-efficacy,and total self-efficacy between the two groups(P=0.795,0.479,and 0.659,respectively).After intervention,these three scores in the research group were higher than those in the control group(P<0.001).Before intervention,there was no significant difference in the scores of SAS and SDS between the two groups(P=0.149 and 0.347,respectively).After intervention,the scores of SAS and SDS in the research group were lower than those in the control group(P<0.001).The standardized drug use rate(97.87%),moderate exercise rate(97.87%),healthy diet rate(95.74%),and regular reexamination rate(97.87%)in the research group were higher than those in the control group(85.11%,82.98%,80.85%,and 87.23%,respectively)(P=0.027,0.014,0.025,and 0.049,respectively).Nursing job satisfaction in the research group(93.62%)was higher than that in the control group(78.72%)(P=0.036).CONCLUSION A nursing program based on Maslow’s hierarchy of needs theory can effectively alleviate negative emotion,enhance self-efficacy and intervention compliance,and ensure that the patients are highly satisfied with the nursing work.

Nursing, Psychological Intervention and Self-Management after Deep Brain Stimulation in Parkinson’s Disease

Parkinson’s disease (PD) is a neurodegenerative disease mainly caused by motor disorders, mostly occurring in middle-aged and elderly people. The incidence of PD has been increasing year by year, and up to now, PD is still an incurable disease. However, more and more data show that early implementation of deep brain stimulation and early medical, psychological, social and other interventions can significantly improve the quality of life and prolong the survival time of patients with Parkinson’s disease (PD). Mental health guidance, cognitive behavioral intervention, psychogenic therapy and scientific nursing for PD patients may improve the functional recovery after Deep Brain Stimulation (DBS) for Parkinson’s disease. This paper discusses the nursing and psychological intervention methods of deep brain stimulation (DBS) implantation in patients with Parkinson’s disease (PD), aiming to scientifically discuss the clinical effect of nursing psychological intervention and improve the quality of life in patients with Parkinson’s disease. Basic nursing and psychological cognitive behavior intervention measures for PD patients can improve the daily activity ability of PD patients, improve the outcome of PD patients, and effectively improve the satisfaction of PD patients with nursing work, which has certain clinical promotion significance.

Non-pharmacological intervention for posterior cortical atrophy

Posterior cortical atrophy(PCA) is a rare neurodegene-rative condition characterized by progressive visual-perceptual deficits. Although the neurocognitive profile of PCA is a growing and relatively well-established field, non-pharmacological care remains understudied and to be widely established in clinical practice. In the present work we review the available literature on non-pharmacological approaches for PCA, such as cognitive rehabilitation including individual cognitive exercises and compensatory techniques to improve autonomy in daily life, and psycho-education aiming to inform people with PCA about the nature of their visual deficits and limits of cognitive rehabilitation. The reviewed studies represented a total of 7 patients. There is a scarcity of the number of studies, and mostly consisting of case studies. Results suggest non-pharmacological intervention to be a potentially beneficial approach for the partial compensation of deficits, improvement of daily functionality and improvement of quality of life. Clinical implications and future directions are also highlighted for the advancement of the field, in order to clarify the possible role of non-pharmacological interventions, and its extent, in PCA.

Designing a Need Based Social Protection Intervention Package for Children and Adolescents Living with HIV and AIDS in Ghana—An Eclectic Perspective on Desired Social Protection Intervention Package/Framework

Background: Designing a need-based social protection intervention for children comes as comprehensive tool for addressing the overall quality of life of HIV positive children. Not much has been examined on what constitute the desired social protection framework for HIV positive children. Methods: This study was informed by a qualitative descriptive exploratory design approach. The study drew insights from the shared perspectives of 27 participants sampled from positive HIV status disclosed children—10 - 17 years, healthcare workers, Social and Development worker, HIV positive caregivers and parents from 7 ART clinics in rural and urban Brong Ahafo and Ashanti regions of Ghana. Data was collected through interviews and two focus group discussions with study participants. Drawing on the emerged themes from the transcripts, thematic content analysis was used to analyze the data using comparative thematic framework approach. Findings: The eclectic perspectives on the type of social protection policy/intervention preferred demonstrated the need for an interrelated and integrated social protection policy. This should not be designed in isolation towards addressing the child vulnerability. The study found that social protection policies aimed at addressing vulnerability levels of children should consider the dual vulnerability situation within which HIV positive children and adolescents are located. A set of unique specific tailored approach and package reflecting minimum combination social protection package to HIV positive children was considered essential for inclusion. The themes that emerged covered social policy/intervention package inclusive of a disease ending/eradication intervention package, cash transfer for children and their caregivers, free comprehensive health insurance integrating all consultancy and laboratory services charges, direct food supplements supply and nutritional support, research, target specified with evidenced-based monitoring. Counseling support and preferential treatment for children visiting ART for treatment were to be included. Conclusion: Combination social protection intervention packages remain the pathway to yielding maximum dividends on any social intervention that seeks to address the vulnerability levels of HIV positive children in Ghana. This should be designed taking into consideration the preference of the main target beneficiaries (HIV positive children) while accounting for the inclusion of the technical expertise of implementing stakeholders in the policy design from conceptualization to evaluation.

The Benefits of Patients’ Information regarding Dietary Habits before Percutaneous Coronary Intervention: A 3- and 6-Month Follow-Up

Aim: To evaluate the benefits of counseling intervention related to dietary habits changes on patients following percutaneous coronary intervention (PCI). Materials and Methods: A randomized counseling intervention study, with a 3- and 6-month follow-up was performed on 230 patients who underwent PCI. They were randomly allocated to the intervention (n = 93) or the control group (n = 137). A 3- and 6-month telephone follow-up was performed for dietary habits evaluation. Data analysis was performed by using the statistical package SPSS, ver. 20.?Results: Compared with control group, intervention group had higher prevalence of hypertension, history of diabetes and dyslipidemias and history of acute myocardial infraction, with no statistical difference. Moreover, patients in control group were more likely to be ex-smokers (p = 0.01). Post hoc tests using the Bonferroni correction revealed that mean TCHOL concentration while patients admitted to hospital differed statistically significantly between the time points of 3 and 6 months (209 ± 67 mg/dl vs 174 ± 34 mg/dl vs 176 ± 36 mg/dl), p= 0.005 and p = 0.042 respectively. However, there was no statistical significant difference between 3 months and 6 months measurements. Mean glucose concentration while patients admitted to hospital differed statistically significantly between the time points of 3 and 6 months (108 ± 40 mg/dl vs 95 ± 21 mg/dl vs 95 ± 23 mg/dl), p =0.009 and p = 0.012 respectively. However, there was no significant statistical difference between 3 months and 6 months measurements, (p = 1.000). Conclusion: A nurse-led program regarding dietary habits modifications on patients undergoing PCI should be performed along with a long-term follow up after hospital discharge.

Mitochondria in Huntington’s disease:implications in pathogenesis and mitochondrial-targeted therapeutic strategies

Huntington’s disease is a genetic disease caused by expanded CAG repeats on exon 1 of the huntingtin gene located on chromosome 4.Compelling evidence implicates impaired mitochondrial energetics,altered mitochondrial biogenesis and quality control,disturbed mitochondrial trafficking,oxidative stress and mitochondrial calcium dyshomeostasis in the pathogenesis of the disorder.Unfortunately,conventional mitochondrial-targeted molecules,such as cysteamine,creatine,coenzyme Q10,or triheptanoin,yielded negative or inconclusive results.However,future therapeutic strategies,aiming to restore mitochondrial biogenesis,improving the fission/fusion balance,and improving mitochondrial trafficking,could prove useful tools in improving the phenotype of Huntington’s disease and,used in combination with genome-editing methods,could lead to a cure for the disease.

Recurrent hemoptysis in pediatric bronchial Dieulafoy’s disease with inferior phrenic artery supply:A case report

BACKGROUND Bronchial Dieulafoy’s disease(BDD)is characterized by the erosion of an anomalous artery in the submucosa of the bronchus.The etiology of pediatric BDD is mainly congenital dysplasia of bronchus and pulmonary arteries,which is different from chronic inflammatory injury of the airway in adult patients.The internal thoracic artery,subclavian artery,and intercostal artery are known to be involved in the blood supply to the BDD lesion in children.CASE SUMMARY We report a case of BDD in a 4-year-old boy with recurrent hemoptysis for one year.Selective angiography showed a dilated right bronchial artery,and anastomosis of its branches with the right lower pulmonary vascular network.Bronchoscopy showed nodular protrusion of the bronchial mucosa with a local scar.Selective embolization of the bronchial artery was performed to stop bleeding.One month after the first intervention,the symptoms of hemoptysis recurred.A computed tomography angiogram(CTA)showed another tortuous and dilated feeding artery in the right lower lung,which was an abnormal ascending branch of the inferior phrenic artery(IPA).The results of angiography were consistent with the CTA findings.The IPA was found to be another main supplying artery,which was not considered during the first intervention.Finally,the IPA was also treated by microsphere embolization combined with coil interventional closure.During the one-year follow-up,the patient never experienced hemoptysis.CONCLUSION The supplying arteries of the bleeding lesion in children with BDD may originate from multiple different aortopulmonary collateral arteries,and the IPA should be considered to reduce missed diagnosis.CTA is a noninvasive radiological examination for the screening of suspected vessels,which shows a high coincidence with angiography,and can serve as the first choice for the diagnosis of BDD.

Theory Critique of Kristen Swanson’s Theory of Caring

Theory is considered essential for integral assessment, adopting its foundations and concepts is of great utility. The theory provides different templates to help nurses provide care that respects patients and improves outcomes. Through understanding the intersection of nursing, patients, health, and the environment, theories aim to simplify the complicated, ever-evolving relationship that nurses have with their profession. Nursing theory helps distinguish nursing as a separate discipline from medicine and related sciences, and assists nurses in understanding their patients and their needs. The behaviors of healthcare providers affect how patients participate in and experience care situations. In the nursing discipline, the theoretical structures of caring have been established as the core concept of guidance in all nurses’ work. The aim of this paper is to develop a critique of Kristen Swanson’s theory of caring—a theory structured around five caring principles (maintaining belief, knowing, being with, doing for, and enabling) by applying it to nursing practice. When applied to nursing practice, each of these five stages stimulates the caregiver’s attitude, which in turn improves the overall patient’s well-being. Implications to nursing practice are mentioned [1] [2].

The Implementation Mode of No-Fly Zones in International Relations

A No-Fly Zone(NFZ)is a unique mode of humanitarian intervention which is understudied in international relations.This article focuses on the political dimension of NFZs in international relations and investigates their implementations by empirically reviewing all three cases of NFZs to date.There may be efforts by intervening states to highlight humanitarian crises among certain targets to secure UN authorization for the NFZs;yet the implementation of NFZs is also driven largely by the security interests of enforcing states.As a result,there is the potential for those states implementing NFZs to transcend legal authorization and sometimes use excessive force,with likely calamitous results for local populations,or in extreme cases,accomplishing regime change by supporting opposition parties in target states.
