Eigen-Property of Single-j System and Seniority Conservation Condition

In this paper we study the system with three nucleons within a single-j shell, which can be described as the angular momentum coupling of a nucleon pair and the odd nucleon. The overlaps between these non-orthonormal states form a special matrix coincidental with the one obtained by Rowe and Rosensteel. They proposed a proposition related to the eigenvalue problems of that matrix and dimensions of the associated subspaces. We prove their proposition with the help of the symmetric properties of the six-j symbols. We also derive algebraic expressions for eigen energies as well as conditions for conservation of seniority through the decomposition of the angular momentum.

Higher intakes of lysine,threonine and valine are inversely associated with non-alcoholic fatty liver disease risk:a community-based case-control study in the Chinese elderly

The associations of individual amino acid with non-alcoholic fatty liver disease(NAFLD)risk remained unclear.The present study aimed to investigate the associations between the two in the Chinese elderly.Methods:A community-based health check-up program was conducted in Qingdao,China.NAFLD was diagnosed by ultrasonography accompanied by epidemiological investigation.The dietary intakes of amino acids were investigated with 3-day,24-h dietary records and calculated by Nutrition Calculator software.Restricted cubic spline model was used to evaluate a nonlinear relationship between amino acid intake and NAFLD risk.Results:400 NAFLD subjects were identified,and 400 participants were randomly selected as controls and matched by gender and age(±3 years)Dose-response analysis showed that 1000 mg increment of aromatic amino acids(AAAs)was associated with reduced 16%risk of NAFLD.Dietary increments of 750 mg/d threonine,950 mg/d valine,or 1700 mg/d lysine were associated with a 20%reduction in the NAFLD risk(all P for linearity<0.05).Conclusion:The present study demonstrated that the dietary increases in milk,eggs and deep-sea fish,which are rich in the amino acids,might contribute to protecting against NAFLD in the elderly.

Predictive value of systemic immunity index for sepsis in low-medium risk community-acquired pneumonia

Objective:To assess the predictive value of systemic immune inflammation index(SII)for sepsis in low-and medium-risk community-acquired pneumonia.Methods:A total of 589 elderly patients with low-and medium-risk community-acquired pneumonia admitted to the Emergency Department of the Second Affiliated Hospital of Hainan Medical University from January 2020 to January 2023 were included as the research subjects,and the general information and laboratory test results of the patients were collected,and the optimal cut-off value of continuous variables for predicting sepsis in elderly patients with low-and medium-risk community-acquired pneumonia was determined by plotting the receiver work characteristic(ROC)curve,which was converted into dichotomous variables and univariate and multivariate logistic Regression analysis of the influencing factors of sepsis in elderly patients with low-and medium-risk community-acquired pneumonia.Based on this,a nomogram model is constructed to predict the risk of sepsis.The differentiation,consistency and accuracy of the model were verified by calibration curve and subject operating characteristic(ROC)curve,and the clinical utility of the model was determined by decision curve analysis.Results:A total of 589 elderly patients with low-and intermediate-risk community-acquired pneumonia were included in this study,of which 96(16.30%)developed sepsis.There were significant differences in age,diabetes mellitus and chronic obstructive pulmonary disease,Lac,PCT,SII and other indexes between sepsis and non-sepsis groups(P<0.05).Logistics regression analysis showed that age,diabetes mellitus and chronic obstructive pulmonary disease,Lac,and SII were independent risk factors for sepsis in elderly patients with low-and medium-risk community-acquired pneumonia.The nomogram prediction model was used to verify the results,and the AUC was 0.826(95%CI:0.780-0.872),and the calibration curve tended to the ideal curve with good accuracy.The decision curve shows that when the threshold of the model is between 0.10~0.78,the model has the advantage of clinical benefit.Conclusion:The nomogram prediction model constructed based on SII to predict sepsis in elderly patients with low-and medium-risk community-acquired pneumonia has good accuracy,which can predict the occurrence of sepsis early,help early identification of high-risk groups and timely intervention,and thus improve the prognosis of patients.

Frailty in People Living with Human Immunodeficiency Virus Aged 50 Years and Older: Prevalence and Predictors

Introduction: Life expectancy improvement for people living with Human Immunodeficiency Virus (HIV) is coming up against the problems associated with aging and chronic diseases. Frailty is a concern affecting a growing number of patients, particularly the elderly in this population. Our study aimed to determine the prevalence of frailty and its predictors on people living with HIV aged 50 years and older followed at the Outpatient Treatment Clinic (CTA) in Dakar. Methodology: We conducted a cross-sectional study of descriptive and analytic purposes ranging from November 2022 to August 2023, in CTA, Dakar (Senegal). We included people living with HIV aged 50 years and older under antiretroviral therapy for at least 6 months (≥6 months). Frailty was considered according to Fried criteria with a score ≥3. To identify the predictors of frailty, we performed a multivariate logistic regression analysis using STATA software version 18. Results: We included 199 patients. The median age at the moment of the study was 58 years old [50 - 91] with a sex ratio (M/F) of 0.58. The most representative age group was that of [50 - 59] years (59.3%). HIV-1 profile was most common in 89.45%. The median duration under antiretroviral therapy was 180 months [6 - 284] and 94% of patients received a Tenofovir Disoproxil Fumarate (TDF)-containing regimen with 43% of them for at least 10 years. Viral load was undetectable (≤40 copies/ml) in 98% of cases. WHO Stage III was more common at inclusion and 55.78% had nadir TCD4+ Lymphocyte counts Conclusion: Our study confirms the high prevalence of frailty among older people living with HIV. Its prevention should consider the management of comorbidities and the implementation of non-pharmacological interventions such as nutrition.

Short Video Craze at a Nursing Home

Short videos shot at a nursing home in the northern Chinese city of Tianjin are aimed at enriching the inner world of its elderly residents and maintaining their optimistic life view.Agroup of senior citizens face the camera and deliver lines from a scripted sketch ending with the homespun homily,“There are some parents who always compare their children with other people’s children,but they never think to compare themselves with other parents.”The occasional bloopers of these senior players make fellow actors fall about laughing.But rather than reproving them,the director joins in the merriment.This is not a stage rehearsal or movie set scenario,but a video shooting taking place at a nursing home in the northern Chinese city of Tianjin.Since last April,Jingya Nursing Home,in an effort to enrich the lives of its elderly residents,has taken the new approach of shooting short videos.These have since attracted nearly a million followers and scored over six million likes on Douyin,the Chinese version of TikTok.

Seniority and (9/2)^(n) configurations in neutron-rich Nickel isotopes

Excited states in low-energy spectra of ^(70-76) Ni are considered. Accordingly, pairing forces in the form of surface delta interaction are employed to account for the formation of the ground state multiplet with seniority v= 2 states. The multiplet splitting is described with mass relationships of masses of neighboring nuclei. Subsequently, the seniority model is adopted to reproduce or predict the states v= 3 in odd-even isotopes and v= 4 in even-even isotopes. The correct account of the 2^(+)_(1) state should allow for the description of the reversed order of J = 4 states with v= 2 and v= 4 observed in experiments. The results obtained are compared with the structure of similar multiplets in N=50 isotones.

Influences of Horticultural Therapy and Functional Recovery Training at a Day-Care Center for the Elderly and Text Mining of Care Records by AI

Background: In Japan, due to the COVID-19 pandemic, various behavioral restrictions were implemented from March 2020, resulting in an increased number of elderly people with reduced participation in care and rehabilitation. As a result, the decline in motor and cognitive functions became more pronounced. Purpose: The study examined how activities combining passive horticultural therapy, which is always introduced, with active functional recovery training, which is used in the functional recovery training of patients with hemiplegia, influence the behavior of elder people using the facility. Methods: 36 elder people with care need 1 or 2 who regularly used the day-care facilities after the pandemic ended and who agreed to participate in the study was included. The assessment data were every three months from December 2021 to December 2023 after the COVID-19 pandemic, the MMSE and Moca-J, TMIG-Index, and GDS15. AI-based text mining was used to compare changes in visit reports before and after the introduction of the Posture Chart and Red Code, and the relationship between the language used. Results: The results of MMSE and Moca-J were both significantly higher in Group B and C than in Group A. TIMG assessment, was significantly higher in Group B and C than in Group A, and Group C was significantly higher than Group B. The GDS, an assessment of depression in old age, tended to be significantly higher in Group A than in Groups B and C. In the “Co-Occurrence Network Analysis” shown after the introduction of the latest functional recovery training equipment such as the Red Cord, its results showed a high association between the words Bathing and CARE and words such as POSTURE, Red-Code, and AI, App, which are used in functional training and rehabilitation, and their analysis. Conclusion: At day-care facilities specializing in functional recovery training and rehabilitation, a combination of horticultural therapy and the latest functional training equipment found to help maintain the physical and mental health of elderly people certified as requiring nursing care. Since this is a short-term study following behavioral restrictions, long-term research should continue to study the effects of adding functional training, handled by rehabilitation professionals, to horticultural therapy.

Friendly Exchanges Promote Pragmatic Cooperation

The past month saw Chinese leaders and senior diplomats engage in a flurry of diplomatic activities and interchanges.In Xi’an,an ancient city once serving as the capital of 13 dynasties in Chinese history,President Xi Jinping chaired the China-Central Asia Summit,the first in-person gathering attended by the heads of state of six countries,since China established diplomatic ties with them 31 years ago.The milestone summit added considerable impetus to relations between China and Kazakhstan,Kyrgyzstan,Tajikistan,Turkmenistan,and Uzbekistan,and started a new chapter in their cooperation.In Europe,meanwhile,Vice President Han Zheng,senior diplomat Wang Yi,and Foreign Minister Qin Gang met with European leaders in a concerted attempt to find more common ground for pragmatic cooperation between China and European countries–an intention echoed by their European counterparts.

Responsibility Distribution Between the Government and Society in Guaranteeing Basic Senior Care Services

The 20th National Congress of the Communist Party of China put forward the task to ensure all elderly people enjoy basic senior care services.In an aging society,basic senior care services are key to protecting the basic human rights of the elderly.The government-society partnership is an ideal model to guarantee basic senior care services.In terms of responsibility distribution,the government and social organizations should follow the principle of subsidiarity.On the one hand,social organizations undertake the responsibility to provide basic senior care services under public constraints with regard to service prices,service content,and service targets;On the other hand,the government is the responsible guarantor for minimum senior care services and the prevention of risks.The government’s responsibility of guaranteeing minimum senior care services lies in the government taking over relevant projects after the occurrence of risks.Constrained by the principle of subsidiarity,the government’s responsibility for risk prevention shifts from ex-ante prevention to interim and ex-post prevention.Emphasis should be placed on the principle of the government and society assuming shared responsibilities for risk prevention and achieving risk prevention through government spending.
