Effectiveness and safety of subthreshold vibration over suprathreshold vibration in treatment of muscle fatigue in elderly people

Muscle fatigue is common in many populations,particularly elderlies.Aging increases the incidence of muscle fatigue and delays its recovery.There is a huge debate about the current treatments for muscle fatigue,particularly in elderlies.Recently,it has been discovered that mechanoreceptors have an important role as a sensory system in sensing muscle fatigue which could enhance the body's response to muscle fatigue.The function of mechanoreceptors could be enhanced by applying either suprathreshold or subthreshold vibration.Although suprathreshold vibration improves muscle fatigue,it can cause desensitization of cutaneous receptors,discomfort,and paresthesia,which are barriers to clinical use.Subthreshold vibration has been approved as a safe and effective method of training for mechanoreceptors;however,its use and effectiveness in muscle fatigue have never been tested or explained.Possible physiological effects of subthreshold vibration in the treatment of muscle fatigue include:(1)Enhancing the function of mechanoreceptors themselves;(2)Increasing the firing rate and function of alpha motor neurons;(3)Increasing blood flow to fatigued muscles;(4)Decreasing the rate of muscle cell death in elderlies(sarcopenia);and(5)Driving motor commands and allow better performance of muscles to decrease fatigue incidence.In conclusion,the use of subthreshold vibration could be a safe and effective treatment for muscle fatigue in elderlies.It could enhance recovery from muscle fatigue.Finally,Subthreshold Vibration is safe and effective in treating muscle fatigue in comparison to suprathreshold vibration.

Pressure Ulcers in Institutionalized Elderly People:Association of Sociodemographic and Clinical Characteristics and Risk Factors

As for risk factors, the most important was fecal incontinence (p Conclusion: The analysis of the associations pointed out problems that require intervention in order to prevent health implications of the elderly people and to minimize the risk and occurrence of this injury.

Can statins reduce risk of lung cancer,especially among elderly people? A meta-analysis

Objective： As the most common cause of cancer mortality throughout the world, lung cancer has drawn people＇s attention on how to reduce the risk with chemopreventive ways. Many epidemiological studies have shown inconsistent effects of statins on lung cancer, but some observational studies have showed that statins had protective effect on lung cancer among elderly people. So we preformed this meta-analysis to find whether statins were chemopreventive. Methods： We searched MEDLINE, EMBASE and Web of Science databases from inception to September, 2013. A total of 23 studies were selected, including 15 observational studies and 8 randomized controlled trials （RCTs）. Both fixed and random-effects models were used to calculate pooled estimates in primary and sensitivity analyses. We used Q and 12 statistics to assess statistical heterogeneity, and evaluated publication bias by Begg＇s test and Egger＇s test. Results： No association between statins and lung cancer risk was identified either in the meta-analysis among RCTs [relative risk （RR）： 0.95, 95% confidence interval （95% CI）： 0.85-1.06] or observational studies （RR： 0.89, 95% CI： 0.77-1.04）. We also selected 6 observational studies that all researched on elderly people. The result of meta-analysis showed that there was still no protective effect between statins and lung cancer among elderly people （RR： 1.03, 95% CI： 0.96-1.11）. Conclusions： Our results did not support a protective effect of statins on the overall lung cancer risk and the lung cancer risk among elderly people. More well-designed RCTs are needed to enhance our understanding of the chemopreventive effect of statins on lung cancer.

Blood Glucose Sensor Systems for Elderly People

Electrochemical blood glucose sensors were developed with use of enzymes and an electron mediator.Electrodes were patterned on a resin plate,and a reagent layer containing an enzyme and an electron mediator was disposed on the electrodes in a dried state.A sample chamber to which the soluble reagent layer was exposed was assembled with the enzyme-loaded electrodes to hold a certain volume of blood in the sensor.The fabricated sensors enabled rapid and precise measurements of blood glucose of oneself.The sensor systems combined with the customized hand-held meter especially for the sensor were maintenance-free chiefly due to disposable sensors,and would be simple and easy enough to be operated by elderly people.

Public Square Dancing Intervention on Subjective Well-Being of Middle-Aged and Elderly People:A Meta-Analysis

Objective:To understand the influence of public square dancing on the subjective well-being of middle-aged and elderly people.Methods:According to the principle of Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines,we search Chinese databases,such as CNKI,Wanfang Data,and VIP,and English databases,such as Proquest,Web of Science,Pubmed,Cochrane,and ScienceDirect,and collect relevant articles at home and abroad from 2006 to December 2019 for meta-analysis in January 2020.Result:A total of 10 articles were included.The meta-analysis results showed that the well-being of middle-aged and elderly people in the public square dancing intervention group was significantly higher than that of the other exercise group and control group(both P<0.01).The results of the subgroup analysis showed the following:Different durations of intervention significantly influence the intervention effect(P<0.01).No difference was found between the effect of the mixed-gender intervention and the individual female intervention(P>0.05).No significant difference was found between the groups with weekly intervention frequency(P>0.05).Conclusion:Public square dancing intervention is effective for middle-aged and elderly people’s subjective well-being.Neither mixed intervention nor the times of weekly intervention have an impact on the intervention effect.However,the length of duration of intervention influences the intervention effect.

Behavioral Risk Factors for Chronic Non-Communicable Diseases in Adults and Elderly People in the City of Ribeirão Preto—SP

Aims: to analyze the presence and simultaneity of behavioral risk factors for chronic non-communicable disease (NCD) in adults and the elderly. Methods: quantitative, cross-sectional and observational study. Healthy and unhealthy eating are classified according to the frequency of food consumption. Smoking is expressed by the percentage of smokers. Harmful alcohol consumption by the percentage of individuals who consumed alcoholic beverages at least once in the last 30 days. Classification of the level of physical inactivity required to practice at least 150 minutes of physical activity. Results: the sample constituted 719 people, 535 adults and 184 elderly. The behavioral risk factor reported by most adults 499 (93.3%) and elderly 156 (84.8%) was unhealthy eating. Frequency 72% higher of smoking, four times higher of harmful alcohol consumption and 10% higher of unhealthy food among adults when compared to the elderly. The simultaneity between risk factors was 39% greater in adults than in the elderly. Discussion: risk factors evaluated in this study are key aspects of the development of NCDs. Adults have 2.43 times the chance of presenting two risk factors and 7.73 times the chance of presenting three in relation to the elderly. Conclusion: To achieve more effective and differentiated results, knowing and directing measures to control behavioral risk factors, whether isolated or concurrent, requires specific knowledge.

Effects of the self-management training program on self-management behavior and blood pressure levels among elderly people with hypertension

Objective:To determine the effects of the Self-Management Training Program on self-management behavior and blood pressure(BP)levels among elderly people with hypertension(HT).Methods:This study was based on a quasi-experimental design using sampling groups composed of elderly residents of Pathum Thani Province with HT.Simple random sampling was applied to two sampling groups,an experimental group and a control group.However,the experimental group had been on the Self-Management Training Program based on the Creer concept.The Program’s contents included small-group health-education sessions and the patients’manual,Self-Management Training Skills for Self-Management Behavior.Small group discussions were held for self-reflection,to stimulate follow-up for self-management behavior training during home visits.The Self-Management Training Program was compared with programs involving the more usual care.Data were collected using the Self-Management Behavior for Hypertension Control Questionnaire and BP assessment tests.Data were analyzed using a descriptive statistic,chi-square test,pair t-test,repeated-measures Analysis of Variance(ANOVA),and repeated-measures Analysis Covariance(ANCOVA).Results:It was found that at 13 weeks after entering the program,the experimental group demonstrated a significantly lower systolic and diastolic BP with a baseline statistical significance(P<0.005),and that at the 4th week and the 13th week,there was a decrease in BP in the experimental group.The experimental group also had above-baseline self-management behavior scores that were higher than in the control group(P<0.01).Conclusions:Results from this study show that the Self-Management Program was useful for BP control and promoted sustainable self-management behavior.

Effects of Water Immersion in Different Water Depths on Respiratory Function and Respiratory Muscle Strength among Elderly People: An Observational Study

The aim was to investigate the effect of three water levels (umbilical, 4th rib, and clavicular) on the respiratory function and respiratory muscle strength among elderly. Spirometry and respiratory strength were measured on land as baseline data. Next, water depth conditions were determined randomly, and spirometry and respiratory muscle strength were measured at each water level. The Vital Capacity and Expiratory reserve volume in the clavicular level were significantly lower than those in the land and umbilical trials. No significant difference was observed in other respiratory functions. Chest circumference and respiratory muscle strength were not significantly different among all conditions.

Virtual Nursing Using Deep Belief Networks for Elderly People (DBN-EP)

The demand for better health services has resulted in the advancementof remote monitoring health, i.e., virtual nursing systems, to watch and supportthe elderly with innovative concepts such as being patient-centric, easier to use,and having smarter interactions and more accurate conclusions. While virtual nursing services attempt to provide consumers and medical practitioners with continuous medical and health monitoring services, access to allied healthcare expertssuch as nurses remains a challenge. In this research, we present Virtual NursingUsing Deep Belief Networks for Elderly People (DBN-EP), a new framework thatprovides a virtual nurse agent deployed on a senior citizen’s home, workplace, orcare centre to help manage their health condition on a continuous basis. Using thismethod, healthcare providers can assign various jobs to nurses by utilizing a general task definition mechanism, in which a task is defined as a combination ofmedical workflow, operational guidelines, and data gathered from a remotelymonitored virtual nursing system. Practitioners are in charge of DBN-EP andmake treatment decisions for patients. This allows a DBN-EP to act as a personalized full-time nurse for a client by carrying out practitioner support activitiesbased on information gathered about the client’s health. An electronic PersonalHealth Record (ePHR) system, such as a specialized web portal and mobile apps,could provide such patient information to elderly person family members and carecentres. We created a prototype system using a DBN-EP system that allows traditional client applications and healthcare provider systems to collaborate. Finally,we demonstrate how this system may benefit the elderly through a result anddebate.

The Impact of a Pet, in This Case a Dog, on Physical Activity, Independence, Social Contacts, Health and Quality of Life of Elderly People

In a rural area near Munich, 52 persons aged 65 years and older were interviewed in person about health and social life circumstances. Findings: Dog owners take significantly longer walks than people who do not own dogs, averaging more than 120 minutes daily (p < 0.0001). On average, people who do not own a dog walked 38 minutes, cat owners 17 minutes. 94% of the dog owners were active daily compared to 14% of those who do not own a dog. Dog owners go to the doctor on average 5.3 times per year, people who do not own a dog 7.8 times. There was no difference between the two groups in regard to the use of medication. 80% would not move to a residential home for the elderly because of the dog, and 87% would want to take the dog along. 50% of the dog owners and 41% of those who do not own a dog had on average more than 3 contacts with other people, 6% of the dog owners and 23% of those who do not own a dog had less than one contact per day. 19% of the dog owners and 36% of those who do not own a dog would describe themselves as reserved in dealings with people. 71% stated that the dog had been very useful to help them overcome the loss of a person close to them. The W-5 [Wellbeing Five score] for dog owners was an average value of 75%, for those who did not own a dog 71%. Depression was uniformly distributed in both groups. The BMIs in both groups were similar. There was no correlation to the length of the daily walk.

An overview report on the situation of elderly people in urban and rural China:2000-2015

China had become a country with an aging population by the end of the 20th century.Dealing with the aging of its population is a long-term strategic task for China.“The National Survey on Elderly People in Urban and Rural China”has been carried out four times since the year 2000.The data shows that during the years 2000 to 2015 the wellbeing of elderly people in urban and rural China improved greatly.The economic status of the elderly has obviously improved;and there have also been steady improvements to social security protections,health care services and the availability of social activities in which the elderly can participate.In addition,the spiritual and cultural life of the elderly has become richer and more colorful.The aging of society creates challenges,such as potential shortages of labor resources,the weakening of family functions and the need for more medical care facilities and services,and these intensify over time.At the same time,changes to the structure of demand and of industry caused by societal aging bring many opportunities.

Aged People in Chinese Society and Housing Planning for the Elderly People

China is galloping to a society of aged people,accord-ing to the Fourth National Population Survey,there hasbeen 97.38 million people over 60 years of age,accountingfor 8.59% of the total population.In other words,there hasbeen an increase of 0.95 Percentage than that of the ThirdNational Population Survey in 1982.The number of elderlypeople increased in the 8 years period at the annual rate of3.02%,which was one time higher than the average total in-crease(1.48). Five cities and provinces,namely,Shanghai,Beijing,Tianjin,Zhejiang Province and Jiangsu Provincehave already become aged society.By the end of 1991,elder-ly People has reached 100 million.It is estimated that by2000, China will enter aged People’society with the totalamount of 131 million elderly people,accounting for 10%of the total population.Problems of the elderly People are vitally important so-cial issues.We often say that the children are the future ofmankind and there is no hope for the human being Withoutthe healthy development of

Analysis of the impact of exercise education interventions on middle-aged and elderly people in Central-western rural China

This study aims to analyze the impact of health education effort that promote exercise activities have had on middle-aged and older people in central-western rural China.The Project for Family Health Care(PFHC)of the population in central and western China used questionnaires completed anonymously to survey 4217 randomly selected respondents in the baseline year of 2011,and 4529 in the end-line year of 2015.We used bivariate and multivariate analyses to examine the associations between several factors and regular exercise activities.The 2011 baseline year sample indicated that 90.5%of respondents knew the functions of regular exercise,but that only 45.4%participated in regular exercise activities.In the baseline multivariate model,a number of factors were positively associated with the prevalence of participation in regular exercise activities.Respondents who were women,older,retired,lived with children,had chronic diseases,and self-reported better health were more likely to participate in regular exercise.The proportion of those participating in regular exercise increased to 75.9%among the end-line year respondents after health education.This study revealed that health education interventions effectively encouraged rural middle-aged and elderly people to participate in regular exercise activities.Health education efforts of this sort for rural middle-aged and older adults should be further strengthened,and more public facilities for exercise should be provided.

Power Law for the Rates of Different Numbers of Chronic Diseases among Elderly Chinese People

Chronic disease is an important factor that affect the health of elderly people. We analyzed the 2006 and 2010 data from the Chinese Urban and Rural Elderly Population Surveys, which are nationally representative surveys of elderly people aged 60 years and above. We found that there existed a typical power-law distribution for the rates of different numbers of chronic diseases among elderly Chinese people. A Kolmogorov-Smirnov test indicated that the result was robust, and the power exponents were approximately ?2.5. In addition, a paired t-test was conducted, which demonstrated that the rates of different numbers of chronic diseases did not have significant urban-rural differences, time differences or gender differences.

Assessment of Falls among the Elderly in the Emergency Department of the Idrissa Pouye General Hospital in Dakar, Senegal: A Cohort of 100 Cases

Background: Falls in the elderly are a global public health problem with serious medical and socio-economic consequences, especially in low and middle-income countries. The aim of this study was to describe the characteristics of falls among the elderly in trauma units in Senegal. Materials and Methods: This was a descriptive, prospective study from April 20, 2022 to October 30, 2022 among people aged at least 60 and admitted to the surgical emergency department of Idrissa Pouye Hospital in Dakar following a fall. Socio-demographic, clinical, therapeutic and evolutionary characteristics were collected and analyzed using Sphinx Plus 2 and Excel 2019 for Windows software. Results: Out of 730 elderly people seen during this period, 100 met the criteria, representing a prevalence of 13.69%. The average consultation time was 3.25 +/? 4 days. The average age was 73 +/? 8.43 years, with women predominating (74%). Medical expenses were mainly covered by the family (73%). Most falls occurred during the day (68%), at home (82%), especially in the bedroom (30%), with stumbling (32%) as the main mechanism. The majority of patients (86%) spent less than 30 minutes on the floor. Predisposing factors were dominated by visual disorders (56%) and precipitating factors were mainly environmental (62%). Geriatric syndromes were dominated by frailty (22%). Complications were dominated by fractures (86%), and almost half (47%) had lost their autonomy for post-fall Activities Daily Living (ADL). Prescription medication was almost systematic (98%), dominated by analgesics (98%). Surgery was indicated in 58% of patients. The average waiting time for surgery was 25.36 +/? 19 days. A death rate of 1% was recorded in the emergency department. Conclusion: Falls in the elderly are a frequent occurrence in traumatological emergencies, with etiological factors that are often multiple and interrelated, leading to significant morbidity. Raising awareness among people at risk and setting up an orthogeriatric service would help prevent falls and optimize care in the short and long term.

Vision Based Real Time Monitoring System for Elderly Fall Event Detection Using Deep Learning

Human fall detection plays a vital part in the design of sensor based alarming system,aid physical therapists not only to lessen after fall effect and also to save human life.Accurate and timely identification can offer quick medical ser-vices to the injured people and prevent from serious consequences.Several vision-based approaches have been developed by the placement of cameras in diverse everyday environments.At present times,deep learning(DL)models par-ticularly convolutional neural networks(CNNs)have gained much importance in the fall detection tasks.With this motivation,this paper presents a new vision based elderly fall event detection using deep learning(VEFED-DL)model.The proposed VEFED-DL model involves different stages of operations namely pre-processing,feature extraction,classification,and parameter optimization.Primar-ily,the digital video camera is used to capture the RGB color images and the video is extracted into a set of frames.For improving the image quality and elim-inate noise,the frames are processed in three levels namely resizing,augmenta-tion,and min–max based normalization.Besides,MobileNet model is applied as a feature extractor to derive the spatial features that exist in the preprocessed frames.In addition,the extracted spatial features are then fed into the gated recur-rent unit(GRU)to extract the temporal dependencies of the human movements.Finally,a group teaching optimization algorithm(GTOA)with stacked autoenco-der(SAE)is used as a binary classification model to determine the existence of fall or non-fall events.The GTOA is employed for the parameter optimization of the SAE model in such a way that the detection performance can be enhanced.In order to assess the fall detection performance of the presented VEFED-DL model,a set of simulations take place on the UR fall detection dataset and multi-ple cameras fall dataset.The experimental outcomes highlighted the superior per-formance of the presented method over the recent methods.

Zinc Absorption from Representative Diet in a Chinese Elderly Population Using Stable Isotope Technique

Objective To determine the dietary zinc absorption in a Chinese elderly population and provide the basic data for the setting of zinc （Zn） recommended nutrient intakes （RNI） for Chinese elderly people. Methods A total of 24 elderly people were recruited for this study and were administered oral doses of 3 mg 67Zn and 1.2 mg dysprosium on the fourth day. The primary macronutrients, energy, and phytic acid in the representative diet were examined based on the Chinese National Standard Methods. Fecal samples were collected during the experimenta and dysprosium content. period and analyzed for zinc content, 67Zn isotope ratio, Results The mean （± SD） zinc intake from the representative Chinese diet was 10.6 ± 1.5 mg/d. The phytic acid-to-zinc molar ratio in the diet was 6.4. The absorption rate of 67Zn was 27.9% ±9.2%. The RNI of zinc, which were calculated by the absorption rate in elderly men and women, were 10.4 and 9.2 mg/d, respectively. Conclusion This study got the dietary Zn absorption in a Chinese elderly population. We found that Zn absorption was higher in elderly men than in elderly women. The current RNI in elderly female is lower than our finding, which indicates that more attention is needed regarding elderly females＇ zinc status and health.

Application of a perioperative nursing strategy in the surgical treatment of elderly patients: a narrative review

With the steady increase of older people in society, a progressively greater number of patients belonging to the geriatric group need surgical treatment. Since elderly patients with reduced physiological reserve and organ failure often have chronic diseases, geriatric syndrome, and other clinical problems, the perioperative nursing of elderly patients is more complicated. Therefore, we need to comprehensively consider clinical issues, such as patients’ preoperative status, surgical risks, and postoperative quality of life and life expectancy, and conduct comprehensive evaluations and holistic, individualized, and continuous nursing and therapy through the participation of interdisciplinary teams to achieve better curative effects. Here, the perioperative nursing of elderly patients is reviewed, including preoperative evaluation and nursing, intraoperative management, and postoperative nursing.
