INTRODUCTION:
Conservative kidney management (CKM) is a recognised treatment option for selected patients with chronic kidney disease stage 5 (CKD G5), but prognostic indicators for mortality and optimal timing for palliative care transition remain uncertain.
METHOD:
This is a single-centre, prospective cohort study of CKD G5 patients who opted for CKM, conducted between April 2021 and September 2024, with longitudinal monitoring of Edmonton Symptom Assessment System Revised: Renal; Palliative Perfor-mance Scale (PPS); Resources Utilisation Group.Activities of Daily Living (RUG-ADL) scale; Clinical Frailty Score; Karnofsky Performance Score; and clinical and laboratory data. Primary outcomes included identifying baseline mortality predictors and validating the PPS for survival estimation. Cox proportional hazards models were used to identify independent predictors of mortality.
RESULTS:
Among 109 patients (mean age 79.8±7.3 years, 64.2% female), 62 (56.9%) died during follow-up. Multivariate analysis identified baseline estimated glomerular filtration rate (eGFR) (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.08.1.68, P<0.01) and serum albumin (HR 1.24, 95% CI 1.08.1.43, P<0.01) as predictors of 1-year mortality. Median survival varied by eGFR: 3.0 months (95% CI 0.6.2) for eGFR .5 mL/min/1.73 m2, 13.0 months (95% CI 9.1.16.9) for eGFR 6.10 mL/ min/1.73 m2, and 20.0 months (95% CI 16.5.23.5) for eGFR >10 mL/min/1.73 m2 (P<0.01). Subsequent PPS correlated strongly with survival, with median survival of 1.8 months for PPS <50, 5.3 months for PPS 50.60, and 7.9 months for PPS 70.80 (P=0.03).
CONCLUSION
Baseline eGFR and serum albumin predict 1-year mortality in CKM patients. PPS offers a practical tool for identifying patients requiring palliative care transition, supporting personalised care pathways and timely integration of palliative care.

OBJECTIVES:
This study aimed to investigate the potential mediating role of plasma phosphorylated tau217 (p-tau217) in the association between periodontitis and mild cognitive impairment (MCI).
METHODS:
In this case-control study, patients diagnosed with MCI in the Neurology Department of the First Affiliated Hospital of Shandong Second Medical University from November 2023 to May 2024 were selected as the case group (MCI group). Cognitively normal (CN) volunteers, matched for age and education level and recruited from the physical examination center during the same period, served as the control group (CN group). The general demographic data of the study participants were collected. The Beijing versions of the Montreal Cognitive Assessment (MoCA), clinical dementia rating (CDR), and activities of daily living scale (ADL) were used to assess neuropsychological functions. Clinical periodontal examinations were conducted, the periodontal inflamed surface area (PISA) was calculated, and the periodontitis stage was determined in accordance with the 2018 classification. Fasting elbow venous blood samples were collected in the morning, and blood biochemical indicators were measured. Plasma p-tau217 levels were detected using enzyme-linked immunosorbent assay (ELISA). Statistical analyses were performed using t-test, Mann-Whitney U test, chi-square test, partial correlation analysis, multivariate Logistic regression analysis, multiple linear regression analysis, restricted cubic spline (RCS) regression analysis, and mediation effect analysis.
RESULTS:
Among the 192 participants, 96 belong to the MCI group and 96 to the CN group. The prevalence of periodontitis was 63.5% in the MCI group and 43.8% in the CN group, with a statistically significant difference (χ²=7.561, P=0.006). The plasma p-tau217 levels in the MCI group were significantly higher than those in the CN group [7.00 (4.27-9.65) ng/mL versus 2.02 (0.80-3.81) ng/mL, Z=-8.108, P<0.001]. Partial correlation analysis revealed that plasma p-tau217 levels were positively correlated with all the clinical periodontal indices (all P<0.001). After adjustments for baseline covariates, multivariate Logistic regression indicated that periodontitis was an independent risk factor for MCI. Patients with periodontitis had a 1.977-fold higher MCI risk than those without periodontitis (OR=1.977, 95%CI: 1.088-3.594, P=0.025). Moreover, the MCI risk for stage Ⅰ/Ⅱ periodontitis and stage Ⅲ/Ⅳ periodontitis was 1.878 times (OR=1.878, 95%CI: 1.029-3.425, P=0.040) and 2.625 times (OR=2.625, 95%CI: 1.073-6.246, P=0.035) higher than that for patients without periodontitis, respectively. Trend test showed that the MCI risk increased with periodontitis severity (Ptrend=0.016). After adjustments for baseline covariates, multiple linear regression analysis showed that periodontitis was an independent risk factor for increased plasma p-tau217 levels (β=3.309, 95%CI: 2.363-4.254, P<0.001). Compared with patients without periodontitis, those with stage Ⅰ/Ⅱ periodontitis (β=1.838, 95%CI: 0.869-2.806, P<0.001) and stage Ⅲ/Ⅳ periodontitis (β=5.539, 95%CI: 4.442-6.636, P<0.001) had significantly higher plasma p-tau217 levels. In addition, trend test indicated that plasma p-tau217 levels increased with periodontitis severity (Ptrend<0.001). After adjustments for baseline covariates, RCS regression analysis further revealed that PISA had a positive linear dose-response relationship with MCI risk (Poverall=0.002, Pnonlinear=0.344) and plasma p-tau217 levels (Poverall<0.001, Pnonlinear=0.140). After adjustments for baseline covariates, mediation analysis showed that plasma p-tau217 mediated the association between periodontitis and MCI, with a mediation proportion of 13.99% (95% Bootstrap CI: 0.38%-49.39%, P=0.038).
CONCLUSIONS
Periodontitis was independently positively associated with MCI risk, and plasma p-tau217 plays a mediating role in this association.

BACKGROUND
Different activity restrictions in older adults are caused by various factors and these can lead to a lower quality of life. The determination of these factors will provide baseline data in the local setting to help health care workers identify which are significantly associated with daily activity restriction.
OBJECTIVESTo determine the different factors such as age, sex, living arrangement, educational level, more than one hospitalization per year, multimorbidity, polypharmacy, dementia risk, depression, malnutrition, history of fall, visual, and hearing impairment, bladder, and bowel incontinence; if significant association exist between these factors and the development of restriction on activities of daily living (ADL) and instrumental activities of daily living (IADL). Also, to determine the most common ADL and IADL restricted activities among older adults.
METHODSFive hundred forty (540) patients aged 60 and above were interviewed where 270 participants were included in the study through systemic random sampling. The different factors and activity restrictions were collected through one time interview using questionnaires (MGS, AD8, Katz and Lawton scale). Data collected were analyzed and interpreted using t -test, chi square and odds ratio.
RESULTSThe significant factors associated with both ADL and IADL restriction are age (p=.011; p=CONCLUSION
Older adults with more advanced age, visual impairment, bladder, and bowel incontinence are significantly associated with both ADL and IADL, indicating that health related conditions affect mobility. Lower educational level is associated with IADL restriction possibly because IADL activities are more complex and require thinking. Fall history is also significantly associated with IADL restriction because visual problems can affect balance and spatial awareness while depression is significantly associated with ADL due to lower quality of life.

BACKGROUND AND OBJECTIVE
COVID-19 is a novel disease primarily affecting the respiratory system. Of those infected, approximately 20% require management in a hospital-setting which may lead to deconditioning. Measures implemented to control spread of the virus also restricted mobility both in the hospital and community setting. The goal of this study was to describe the patient characteristics (age, sex, comorbidities), hospitalization (length of hospital stay, ICU stay, referral to Rehabilitation Medicine), and long-term functional outcome of patients who have clinically recovered from moderate to critical COVID-19 in terms of participation in activities of daily living.
METHODSThis was a descriptive prospective cohort study conducted at a tertiary government hospital with participant recruitment from September 2020 to February 2021 consisting of clinically recovered adult patients managed as COVID-19 Confirmed via rRT-PCR with moderate, severe, or critical risk status. Descriptive statistics were obtained and multiple regression analysis was done to determine associations between patient demographics and their Barthel Index Scores on follow-up at discharge, one month post-discharge, and six months post-discharge.
RESULTSA total of 63 patients were recruited to our study with an average age of 52.4 years. More recovered patients had fulfilled the criteria of moderate illness (46%), with the most common comorbidity being chronic lung disease (42.1%) and diabetes (42.1%). Almost all had total independence pre-morbidly with better baseline functional scores for the COVID-19 severe population. Majority of the patients (63.5%) were not referred for Rehabilitation services. Across all patients, Barthel Index Score at discharge indicated a significant decline from slight dependence to moderate dependence in performing activities of daily living with the pre-morbid status significantly predicting scores at discharge (β = 0.621, p = 0.001) on multiple regression analysis. Patient demographics, hospitalization and ICU stay and outcome, and referral to Rehabilitation Medicine were not found to be significant factors. In the course of follow up, a high dropout rate was observed across the population and by the end of the study, 57.1% of the participants were alive while among those lost to follow up, 20.6% had expired and the remaining 22.2% had an unknown status.
CONCLUSIONCOVID-19 significantly affects the functional outcome of patients in terms of activities of daily living as measured by the Barthel Index. Preliminary data gathered from our study and the high dropout rate supports the need for better follow-up and selecting a tool that is better able to describe the non-demographic factors affecting functionality and participation in activities of daily living.

OBJECTIVE:
To observe the effects of the Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture on hemorrhagic transformation and limb motor function after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in stroke patients.
METHODS:
A total of 130 stroke patients after rt-PA thrombolytic were divided into an acupuncture group (58 cases, 1 case dropped off) and a non-acupuncture group (72 cases, 7 cases dropped off) according to whether they received acupuncture treatment. Propensity score matching (PSM) was used to match each group, with 38 patients in each group. The patients in the non-acupuncture group received rt-PA thrombolytic therapy and western medical basic treatment. In addition to the basic treatment, the patients in the acupuncture group received Xingnao Kaiqiao acupuncture at Shuigou (GV 26), bilateral Neiguan (PC 6), and ipsilateral Sanyinjiao (SP 6), Chize (LU 5), once a day for 14 days. The incidence of hemorrhagic transformation within 30 days after onset was compared between the two groups. The Fugl-Meyer assessment (FMA) score and activities of daily living (ADL) score were observed at baseline and 30 days, 6 months, 1 year after onset in the two groups. The disability rate at 6 months and 1 year after onset was recorded, and safety was evaluated in both groups.
RESULTS:
The incidence of hemorrhagic transformation in the acupuncture group was 5.3% (2/38), which was lower than 21.1% (8/38) in the non-acupuncture group (P<0.05). At 30 days, 6 month, and 1 year after onset, the FMA and ADL scores of both groups were higher than those at baseline (P<0.01), and the scores in the acupuncture group were higher than those in the non-acupuncture group (P<0.01). The disability rate in the acupuncture group at 1 year after onset was 10.5% (4/38), which was lower than 28.9% (11/38) in the non-acupuncture group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).
CONCLUSION
The Xingnao Kaiqiao acupuncture method could reduce the incidence of hemorrhagic transformation in stroke patients after intravenous thrombolysis with rt-PA, improve their motor function and daily living ability, and reduce the long-term disability rate.

This study aims to analyze the clinical characteristics and genetic variations of two cases with developmental delay and lactic acidosis in a family, and to explore the relationship between genetic variations and clinical features. A retrospective analysis was conducted on the clinical characteristics of two siblings with developmental delay and lactic acidosis who were treated at the Neonatal Department of Children's Hospital of Chongqing Medical University in May 2019 and December 2021, respectively. Whole-exome sequencing was used to detect genetic variations in the affected children. Homology modeling of the BCS1L protein was performed to analyze the structural and functional changes of the protein. The correlation between genetic variations and clinical phenotypes was analyzed. The results showed that the main clinical features of the two affected children in this family were manifestations of mitochondrial respiratory chain complex Ⅲ deficiency, including prematurity, developmental delay, respiratory failure, lactic acidosis, cholestasis, liver dysfunction, renal tubular lesions, coagulation dysfunction, anemia, hypoglycemia, hypotonia, and early death. Whole-exome sequencing revealed a novel deletion mutation c.486_488delGGA (p.E163del) and a novel missense mutation c.992C>T (p.T331I) in the BCS1L gene. Structural analysis of the homology modeling showed that the compound heterozygous mutation had a significant impact on protein function. In conclusion, the novel mutation site c.992C>T (p.T331I) in the BCS1L gene is a "likely pathogenic" mutation, and the compound heterozygous mutation is closely related to the phenotype of mitochondrial respiratory chain complex Ⅲ deficiency.

Objective: To understand the depression status and its influencing factors in elderly patients with MS in China and to explore the correlation between various components of elderly MS and depression. Methods: This study is based on the "Prevention and Intervention of Key Diseases in Elderly" project. We used a multi-stage stratified cluster random sampling method to complete 16 199 elderly aged 60 years and above in 16 counties (districts) in Liaoning, Henan, and Guangdong Provinces in 2019, excluding 1 001 missing variables. Finally, 15 198 valid samples were included for analysis. The respondents' MS disease was obtained through questionnaires and physical examinations, and the respondents' depression status within the past half month was assessed using the PHQ-9 Depression Screening Scale. The correlation between elderly MS and its components and depression and its influencing factors were analyzed by logistic regression. Results: A total of 15 198 elderly aged 60 years and above were included in this study, with the prevalence of MS at 10.84% and the detection rate of depressive symptoms in MS patients at 25.49%. The detection rates of depressive symptoms in patients with 0, 1, 2, 3, and 4 MS abnormal group scores were 14.56%, 15.17%, 18.01%, 25.21%, and 26.65%, respectively. The number of abnormal components of MS was positively correlated with the detection rate of depressive symptoms, and the difference between groups was statistically significant (P<0.05). The risk of depression symptoms in patients with MS, overweight/obesity, hypertension, diabetes, and dyslipidemia was 1.73 times (OR=1.73, 95%CI:1.51-1.97), 1.13 times (OR=1.13, 95%CI:1.03-1.24), 1.25 times (OR=1.25, 95%CI:1.14-1.38), 1.41 times (OR=1.41, 95%CI:1.24-1.60), 1.81 times (OR=1.81,95%CI:1.61-2.04), respectively, more than those without the disease. Multivariate logistic regression analysis showed that the detection rate of depressive symptoms in patients with sleep disorders was higher than that with normal sleep (OR=4.89, 95%CI: 3.79-6.32). The detection rate of depressive symptoms in patients with cognitive dysfunction was 2.12 times higher than that in the average population (OR=2.12, 95%CI: 1.56-2.89). The detection rate of depressive symptoms in patients with impaired instrumental activities of daily living (IADL) was 2.31 times (OR=2.31, 95%CI: 1.64-3.26) higher than that in the average population. Tea drinking (OR=0.73, 95%CI: 0.54-0.98) and physical exercise (OR=0.67, 95%CI: 0.49-0.90) seemed to be protective factors for depression in elderly MS patients (P<0.05). Conclusions: Older patients with MS and its component abnormalities have a higher risk of depression than the average population. Sleep disorders, cognitive impairment, and IADL impairment are important influencing factors for depression in elderly MS patients, while tea drinking and physical exercise may help to reduce the risk of the disease.

Objective: To investigate body mass index (BMI) level, identify the main type of nutritional problem, and describe the population distribution characteristics of BMI among Chinese people aged 80 years or above. Methods: The data of 9 481 oldest-old individuals were obtained from the 2017-2018 Chinese Longitudinal Healthy Longevity Survey. The Lambda-Mu-Sigma method, weighted estimates of BMI, and comparisons by BMI quintiles were used to describe the BMI level and distribution characteristics among the oldest-old. Results: The average age of the participants was (91.9±7.7) years, with P50 of the weighted BMI at 21.9 (95%CI: 21.8-22.0) kg/m2. The result of BMI level showed a decreasing trend with age, with a rapid decline before age 100, and then the trend became slower. There are about 30% of the oldest-old classified as undernutrition, but the prevalence of overnutrition is only about 10%. The population distribution characteristics by BMI quintiles showed the oldest-old with lower BMI levels were likely to have the following characteristics: sociodemographically, to be older, female, ethnic minority, unmarried/divorced/widowed, rural residents, illiterate, with inadequate living expenses, located in Central, South, or Southwest China; regarding lifestyles, lower BMI levels were observed for participants who were smoking, not exercising, lack of leisure activities, or with poor dietary diversity; considering functional status, participants with lower BMI levels were those who have poor chewing ability, disability in activities of daily living, cognitive impairment, hearing loss, visual impairment, or poor self-rated health status. The oldest-old with higher BMI levels were likely to have heart disease, hypertension, cerebrovascular disease, and diabetes. Conclusions: The overall BMI level was low among the Chinese oldest-old and it showed a downward trend with age. Currently, the main nutritional problem among the Chinese oldest-old was undernutrition rather than overweight or obesity. Management of healthy lifestyles, functional status, and diseases would be helpful to reduce the risk of undernutrition among the oldest-old.

Objective: To calculate and compare the healthy life expectancy (HLE) of the middle-aged and elderly in China, the United States, and developing and developed countries in the European Union(EU) and analyze the impact of socioeconomic factors on HLE in different countries or regions. Methods: Four surveys from 2010 to 2019 were brought into the research. The data were collected from the China Health and Retirement Longitudinal Study, Health and Retirement Study, and the Survey of Health, Ageing and Retirement in Europe. Developed and developing countries in the EU were divided into two groups for calculation. Education level, total family wealth, and work retirement status were selected to measure socioeconomic status, and activities of daily living were used as health status indicators. We used the multi-state life cycle table method to calculate the transition probability between different health states and estimate life expectancy and HLE. Results: A total of 69 544 samples were included in the study. In terms of age, the middle-aged and elderly in the United States and developed countries of the EU have higher HLE in all age groups. In terms of gender, only Chinese women have lower HLE than men. Regarding socioeconomic factors, the middle-aged and elderly with higher education levels and total family wealth level have higher HLE. In China, working seniors have higher HLE, while for USA women and developed countries of the EU, retired or unemployed seniors have higher HLE. Conclusions: Demographic and socioeconomic factors impact HLE in different countries or regions. China should pay more attention to the health of women and the middle-aged and elderly retired with lower education and less total family wealth.

This study aims to identify the novel biomarkers of cold-dampness syndrome(RA-Cold) of rheumatoid arthritis(RA) by gene set enrichment analysis(GSEA), weighted gene correlation network analysis(WGCNA), and clinical validation. Firstly, transcriptome sequencing was carried out for the whole blood samples from RA-Cold patients, RA patients with other traditional Chinese medicine(TCM) syndromes, and healthy volunteers. The differentially expressed gene(DEG) sets of RA-Cold were screened by comparison with the RA patients with other TCM syndromes and healthy volunteers. Then, GSEA and WGCNA were carried out to screen the key DEGs as candidate biomarkers for RA-Cold. Experimentally, the expression levels of the candidate biomarkers were determined by RT-qPCR for an independent clinical cohort(not less than 10 cases/group), and the clinical efficacy of the candidates was assessed using the receiver operating characteristic(ROC) curve. The results showed that 3 601 DEGs associated with RA-Cold were obtained, including 106 up-regulated genes and 3 495 down-regulated genes. The DEGs of RA-Cold were mainly enriched in the pathways associated with inflammation-immunity regulation, hormone regulation, substance and energy metabolism, cell function regulation, and synovial pannus formation. GSEA and WGCNA showed that recombinant proteasome 26S subunit, ATPase 2(PSMC2), which ranked in the top 50% in terms of coefficient of variation, representativeness of pathway, and biological modules, was a candidate biomarker of RA-Cold. Furthermore, the validation results based on the clinical independent sample set showed that the F1 value, specificity, accuracy, and precision of PSMC2 for RA-Cold were 70.3%, 61.9%, 64.5%, and 81.3%, respectively, and the area under the curve(AUC) value was 0.96. In summary, this study employed the "GSEA-WGCNA-validation" integrated strategy to identify novel biomarkers of RA-Cold, which helped to improve the TCM clinical diagnosis and treatment of core syndromes in RA and provided an experimental basis for TCM syndrome differentiation.
