Introduction: Elderly people are at increased risk of falls, disability and death due to reduced functional reserve, decline in multiple systems functions, which affects their activities of daily living (ADL) and eventually develop into frailty. The ADL assessment is conducive to early detection to avoid further serious situations. Previous studies on patients' activities of daily living with chronic kidney disease (CKD) are mainly focused on dialysis patients. Little information is available on non-dialysis patients. Patients and Methods: A total of 303 elderly patients with CKD stage 3– 5 who were admitted to our hospital were selected. ADL evaluation was performed on patients at admission, with Barthel index (BI) as the evaluation tool. They were divided into two groups based on BI (≥ 60 and < 60). Demographic information, lifestyle and clinical profile were collected. The risk factors related to ADL were analyzed by univariate and multivariate models. Results: The data of 303 patients enrolled in this study were analyzed. The average age of patients was 84.48± 7.14 years and 62.05% were male. There were 88 patients (29.04%) in BI < 60 group and 215 patients (70.96%) in the BI ≥ 60 group. The average age of subjects in the two groups was 87.47 ± 5.85 years and 83.26± 7.28 years, respectively. On univariate analysis, ADL impairment was associated with many factors, such as age, body mass index, blood lipid, heart rate, smoking history, Charlson comorbidity index (CCI), hemoglobin, serum albumin, BNP, eGFR, etc. Multivariate logistic regression showed that age (OR 1.08, 95% CI 1.00– 1.17, P=0.0390), Charlson comorbidity index (OR 4.75, 95% CI 1.17– 19.30, P=0.0295), and serum albumin (OR 0.80, 95% CI 0.70– 0.92, P=0.0012) were the independent risk factors of ADL impairment. Conclusion: Decline of ADL in CKD patients was independently correlated with age, Charlson comorbidity index and serum albumin. ADL and its influential factors in the elderly CKD patients deserve further attention. [ABSTRACT FROM AUTHOR]

Abstract: Aims/Introduction: Patients with diabetes frequently develop orthostatic hypotension (OH). The present study was designed to examine the relationship of blood pressure (BP) circadian rhythms and outcomes in diabetes with OH. Materials and Methods: In the present study, 173 inpatients with type 2 diabetes were enrolled. Patients were divided into an OH group and a non‐OH group according to the BP changes detected in the supine and standing position. Then, 24‐h ambulatory BP was monitored. Patients were followed up for an average of 45 ± 10 months post‐discharge. Outcomes – death and major adverse cardiac and cerebrovascular events, including heart failure, myocardial infarction and stroke – were recorded. Results: There were 61 patients (35.26%) in the OH group and 112 patients (64.74%) in the non‐OH group. In the OH group, the night‐time systolic BP and night‐time diastolic BP were higher, the blood BP rhythms were predominantly of the riser type (67.21%). OH was as an independent marker of riser type circadian rhythm (adjusted odds ratio 4.532, 95% confidence interval 2.579–7.966). In the OH group, the incidence rates of mortality, and major adverse cardiac and cerebrovascular events were increased significantly compared with those in the non‐OH group (11.48 vs 2.68%, P = 0.014; 37.70 vs 8.93%, P < 0.01). Conclusions: In patients who had type 2 diabetes diagnosed with OH, the BP circadian rhythm usually showed riser patterns, and they had increased rates of mortality, and major adverse cardiac and cerebrovascular events.

Objective: To detect relationship between cellular immunity changes and prognosis in elderly patients with sepsis., Study Design: An observational study., Place and Duration of Study: General Department and Emergency Care Unit, Beijing Chaoyang Hospital, Beijing, China, from January to December 2016., Methodology: Patients who had infection were included in this study, and divided into two groups; those with sepsis and no sepsis. One hundred and forty-one healthy volunteers were chosen to enroll in this study just as a control (control group). Patients were excluded if they were younger than 18 years of age; had hematological or immunological disease; had uncontrolled diabetes; and pretreated with immunosuppressive agents. Patients were further grouped according to age, their T lymphocyte subsets were compared, and their acute physiology and chronic health evaluation II (APACHE II) scores were compared. The 28-day re-hospitalisation rate was followed-up, and the effects of T lymphocyte subsets and APACHE II scores on this rate were statistical analysed., Results: Out of the 687 patients, 350 patients had sepsis (sepsis group), and 337 patients had no sepsis (non-sepsis group). The age of these patients ranged from 19-96 years. CD3+T, CD4+T, CD8+T and natural NK cells were significantly lower in the elderly population, (p< 0.01). CD3+T, CD4+T, CD8+T and NK cells were significantly lower in the sepsis group, compared with patients in the non-sepsis group and control group; and the differences were statistically significant (p<0.05), while APACHE II score was significantly higher (p<0.01). In the sepsis group, compared with the non-elderly population, CD3+T, CD4+T and NK cells were significantly lower in the elderly population; and the differences were statistically significant (p<0.05), while APACHE II score was significantly higher (p<0.05). The 28-day re-hospitalisation rate was associated with CD3+T, CD4+T, CD8+T cells and APACHE II scores (p<0.05)., Conclusion: CD3+T, CD4+T, CD8+T cells and APACHE II scores can be used as independent predictors of the 28-day re-hospitalisation rate.

BACKGROUND Impaired renal function is common among older patients. Deficiency of vitamin D is a frequent phenomenon among patients with impaired renal function, who are likely to develop cardiovascular diseases. This study aimed to explore the association of 25 (OH) D levels with left ventricular mass and arterial stiffness in older patients with impaired renal function. MATERIAL AND METHODS Based on their admission estimate glomerular filtration rate (eGFR), 273 inpatients (≥65 years) were allocated into a normal eGFR group (≥60 ml/min) and an impaired eGFR group (<60 ml/min). The 25 (OH) D levels were measured and the left ventricular mass index (LVMI) was estimated. Pulse wave velocity (PWV) was used to explore arterial stiffness. RESULTS The 25 (OH) D levels of patients in the impaired eGFR group were significantly lower than in the normal eGFR group [(11.92±6.01) μg/L vs. (18.14±8.07) μg/L, p<0.05). LVMI and PWV were both significantly higher in the impaired eGFR group than in the normal eGFR group [(104.89±33.50) g/m2 vs. (92.95±18.95) g/m2, P<0.05; (15.99±3.10) m/s vs. (13.62±2.90) m/s, P<0.05]. After adjusting for age, sex, eGFR, cardiovascular risk factors, serum calcium, and iPTH levels, the inverse association between LVMI and 25 (OH) D, PWV, and 25 (OH) D were statistically significant. CONCLUSIONS Vitamin D level is lower in older patients with impaired renal function. Lower vitamin D levels were correlated with higher left ventricular mass and increased arterial stiffness in older patients.

Chronic renal insufficiency and osteoporosis have become very common among old people in China. Hyperparathyroidism caused by renal insufficiency would result in turbulence of bone metabolism and unbalance between serum calcium and phosphorus. The aim of this study is to investigate the BMD, PTH, CT and 25(OH)-Vit's significance for screening and diagnosing chronic renal insufficiency. In this study, seventy cases with chronic renal insufficiency from Jun. 2010 to Oct. 2013 were selected as the observation group. Meanwhile, another 70 volunteers with normal renal functions were set as the control group. The level of BMD, PTH, CT and 25(OH)-Vit were detected by using ELISA assay. DPX bone density meters (UNIGAMMA X-RAY PLUS) were used for the detection of BMD. The results indicated that BMD levels of the proximal femur (include Troch, Shaft, Total, Neck, Ward) and lumbar vertebra in the observation group were significantly lower while the PTH and CT were significantly higher compared with the control group (P<0.05). A positive correlation was identified between the serum creatinine (Scr) concentrations and CT, PTH, while the correlation with 25(OH)-Vit was considered to be negative. In conclusion, the BMD, PTH, CT, and 25 (OH)-Vit would provide reference in diagnosing and treatment for chronic renal insufficiency. These indexes would be important clinical significance for screening and early diagnose of osteoporosis in these patients.
