RESUMEN
This study aimed to determine the prevalence rate of knee osteoarthritis (OA) and the risk factors for OA in hospitalized elderly patients. We conducted this retrospective study in elderly patients (aged 65 years and older) who were hospitalized in the Geriatric Ward of General Hospital of Guangzhou Military Command of the People's Liberation Army between January 2011 and June 2013, including general condition, present history, past history, physical examination, X-ray results, and disease diagnosis. The prevalence, awareness, and treatment rates of knee OA in hospitalized elderly patients were calculated. Risk factors were computed using multiple logistic regression analysis. Of a total of 267 (17.4%) hospitalized elderly patients diagnosed with knee OA, the prevalence rate of OA was 9.95% in males and 37.76% in females. The rate of awareness among those with OA was 51.68%; the rate of treatment was 83.33%; and the rate of control was 77.39%. The medical expenses for both females (1143±315 yuan month-1) and males (1192±357 yuan month-1) in knee OA patients are higher than that of the non-knee OA group (989±274 yuan month-1, 1038±295 yuan month-1). The risk factors for knee OA include gender (OR=2.448), age (OR=1.124), transportation mode (OR= 8.972), exercise (OR=7.374), bowel evacuation position (OR=5.767), family history of knee OA (OR=2.195), and body mass index (OR=2.469). The prevalence of knee OA is unexpectedly high in hospitalized elderly patients, and the rates of awareness and treatment are less than desirable. Prevention and control measures should be taken in patients with concomitant risk factors.

OBJECTIVE: To investigate the association between the systolic/diastolic orthostatic hypotension (OH-S/OH-D) and myocardial infarction (MI) in the elderly. METHODS: Health screening physical examination were carried in 1081 subjects without MI aged over 65 years in Guangzhou Military region. The orthostatic blood pressure and heart rate were measured in supine position after resting for more than 5 minutes and at 0 and 2 minutes after standing. All the cases were divided into systolic or diastolic group on the basis of definition of orthostatic hypotension and followed up by telephone or inpatient medical records with mean period of 315.8 days. The primary endpoint was MI occurrence. RESULTS: The prevalence of OH in this cohort was 24.5% (OH-S/OH-D: 19.3%/17.2%). Significant differences in the occurrence of OH and OH-S were found in the elderly and the very elderly subjects (≥ 80 years) (26.1% vs 20.1%, P = 0.045 ; 21.0% vs 14.6%, P = 0.018), while no difference was found in OH-D. The prevalence of MI in the OH positive subjects was significantly higher than that in the OH negative subjects, as well as in OH-S or OH-D group. After adjustment of age, supine blood pressure, creatinine and cerebrovascular history by logistic regression, the association was observed between MI and OH (HR 15.635, 95%CI 3.299 - 74.091, P = 0.001), OH-S(HR 8.760, 95%CI 2.487-30.851, P = 0.001)and OH-D(HR 3.889, 95%CI 1.097 - 13.790, P = 0.035). CONCLUSION: OH-S and OH-D hypotension are robust predictors for MI in the elderly.

OBJECTIVE: To analyze the impact of attack frequency as well as therapy strategies on outcome of patients with vasovagal syncope (VVS). METHODS: A total of 159 patients (aged from 15 - 59 years old) with VVS were included in this study. Patients were divided into low frequency (< 3) group (n = 95) and high (≥ 3) frequency group (n = 64) according to the attack frequency in the past 5 years at the primary survey. Patients received one of the three therapies: no treatment, physical therapy, and comprehensive treatment. All cases were followed up with telephone or outpatient visit for 24 months. RESULTS: Incidence of syncope was significantly higher in the high frequency group and in the low frequency group [40.6% (26/64) vs. 11.6% (11/95), P < 0.01]. The overall improvement rate was significantly higher in the low frequency group than that of high frequency group (P < 0.01). Improvement rate was significantly higher in the physical therapy subgroup and the comprehensive treatment subgroup than no treatment subgroup for patients with low attack frequency [81.8% (27/33) vs. 47.1% (8/17), P < 0.05; 82.2% (37/45) vs. 47.1% (8/17), P < 0.05], and in comprehensive treatment subgroup than in physical therapy subgroups observed between and [62.2% (28/45) vs. 31.6% (6/19), P < 0.05] for patients with high attack frequency. CONCLUSION: Outcome is related to previous attack frequency for patients with VVS, physical therapy is effective for reducing the recurrence rate of syncope in VVS patients with low attack frequency while physical therapy combined with pharmacotherapy should be applied for VVS patients with high attack frequency to improve outcome.

OBJECTIVE: To determine the prevalence and clinical characteristics of orthostatic hypotension (OH) in the elderly and retired population. METHODS: A total of 1174 elderly and retired people underwent health screening physical examination in Guangzhou military region were included. The orthostatic blood pressure and heart rate were measured in supine position after resting for more than 5 minutes and at 0 and 2 min after standing. Subjects were divided into OH positive group and OH negative group. Orthostatic hypotension was defined as 20 mm Hg (1 mm Hg = 0.133 kPa) or greater decrease in SBP and/or 10 mm Hg or greater decrease in DBP after standing. RESULTS: The prevalence of OH in this cohort was 25.6% at either 0 or 2 min after standing (21.6% or 20.7% respectively). Incidence of hypertension, myocardial infarction (MI), heart failure (HF), ischemic stroke and diabetes was significantly higher in OH positive group than in OH negative group (all P < 0.05), however, antihypertensive medication was similar between the two groups. CONCLUSIONS: Orthostatic hypotension is common in the elderly and retired population and is associated with increased risk of hypertension, diabetes mellitus and cardiovascular disease.

OBJECTIVE: To investigate the correlation between orthostatic hypotension and cardiovascular risks and hospitalization rate in the elders. METHODS: A total of 1174 people over 65 years old underwent health screening physical examination through a self-made questionnaire at our hospital. Their clinical data were collected. The orthostatic blood pressure and heart rate were measured in supine position after resting for over 5 minutes and at 0 and 2 min after standing. Orthostatic hypotension was defined as 20 mm Hg or greater decrease in SBP or/and 10 mm Hg or greater decrease in DBP after standing. All cases were followed up by telephone or hospitalization medical records for a mean period of 315.8 days. The primary endpoint was the occurrence of such cardiovascular or cerebrovascular events as angina, fatal or nonfatal myocardial infarction (MI), congestive heart failure, sudden cardiac death, ischemic and hemorrhagic stroke. RESULTS: The prevalence of OH was 25.6% in this cohort. Significant differences could be found in the rate of all-cause and cardiovascular-related hospitalization between OH positive and OH negative (45.1% vs 32.5%; 19.1% vs 7.4%); the rates of angina and myocardial infarction in the OH positive group were significantly higher than those in the OH negative group (7.5% vs 3.7%: 4.8% vs 0.5%, P < 0.05); after adjusting for age, supine blood pressure, heart rate and cerebrovascular history by logistic regression, statistical differences could also be observed between OH and angina [P = 0.011, HR (hazard ratio): 2.122, 95%CI (confidence interval): 1.184-3.802 and MI (P < 0.001, HR: 8.995, 95%CI: 2.909 - 27.819)]. CONCLUSION: Orthostatic hypotension may increase the rates of all-cause and cardiovasular-related hospitalization. And it is a robust predictor of angina and myocardial infarction in the elders.

OBJECTIVE: To investigate the morning blood pressure surge (MBPS) and its relationship with 24-hour blood pressure variability and anti-hypertensive drugs in middle-aged and elderly hypertensive patients. METHODS: A total of 521 middle-age and elderly men were surveyed with ambulatory blood pressure monitoring and ambulatory electrocardiograms recordings as well as questionnaire investigation from January 2009 to December 2010. Subjects were divided into MBPS positive group and MBPS negative group according to the level of MBPS [> 35 mm Hg (1 mm Hg = 0.133 kPa) or ≤ 35 mm Hg]. RESULTS: In all the cases, the prevalence of MBPS was 19.4%, of which the elderly and very elderly had higher prevalences (18.9% and 21.8%, respectively) than the middle-aged (5.6%, both P < 0.01). Significant differences could be found in age[(81.6 ± 6.4) years vs (78.7 ± 9.7) years], day mean systolic blood pressure [(132.8 ± 13.3) mm Hg vs (128.8 ± 13.3) mm Hg], fasting blood glucose [(5.96 ± 1.59) mmol/L vs (5.68 ± 1.22) mmol/L] and 24-hour blood pressure variability between the two groups (all P < 0.05). Significant difference could be observed in the prevalence of MBPS between the diuretics-taking group and non-taking group (27.4% vs 17.6%, P < 0.05). CONCLUSIONS: The elderly hypertensive patients are prone to appear MBPS phenomenon. Fasting blood glucose level, 24-hour blood pressure variability may be associated with MBPS. Diuretic antihypertensive treatment may not be conductive for MBPS control.
