ObjectiveTo observe the risk factors for osteoporosis in elderly women in Chengdu Shuangliu County, in order to provide a reference for the prevention of this disease.
MethodsThrough random cluster sampling from 6 communities in Shuangliu County, 276 aged (60-84 years old) women accepted questionnaire survey from May 2010 to October 2012. Their bone mineral density was also measured.
ResultsThe osteoporosis rate in these 276 elderly women was 49.64%. Different occupations had a significant impact on the occurrence of osteoporosis (P<0.05). Osteoporosis rate in elderly women in rural areas was higher than that in urban areas, but there was no significant difference (P>0.05). The rate of women who paid attention to calcium and vitamin D preparations was significantly lower than those with no supplement of calcium and vitamin D preparations (P<0.05). Single factor analysis showed that age, body mass index of age 30, present weight, menopause age, suffering from respiratory diseases were closely related to osteoporosis (P<0.05). Multivariate analysis showed that age, present weight, consumption of milk, menopause age, and respiratory disease history were closely correlated with osteoporosis incidence (P<0.05).
ConclusionThe incidence of osteoporosis in women at age 60 or older in Chengdu Shuangliu County is high. Medical workers should strengthen the health education for those elderly women with osteoporosis and promote a healthy lifestyle and a balanced diet.
Objective To investigate disease constitution of elderly inpatient in the Xuanwu Hospital, Capital Medical University in Beijing in 2011, so as to provide baseline data for further study. Methods Elderly (patients no less than 60 years old) inpatients’ records in the Xuanwu Hospital, Capital Medical University in 2011 were collected. Based on all the diagnosis on hospital discharge records, the diseases were standardized and classified according to the International Classification of Disease, 10th Edition (ICD-10). Data (including general information of the inpatients, all discharge diagnosis, and the distribution of disease type, age and sex) were analyzed through descriptive analysis using Microsoft Excel 2007 software. SPSS 17.0 software was performed for hypothesis test. Results a) The total numbers of elderly inpatients were 13 807 in 2011, accounting for 39.79% of all the inpatients. Males were more than females (male: female=1.26 to 1). The average kind of disease each patient was diagnosed with was 4.41, ranging from 1 to 11. b) The disease spectrum of patients with one disease was nervous system diseases, neoplasms, and digestive system diseases. The primary and secondary diseases of patients with two diseases were mostly circulatory system diseases. c) All the diagnosis included 18 categories, the top 7 were circulatory system diseases, endocrine, nutritional and metabolic diseases, digestive system diseases, respiratory system diseases, and nervous system diseases, accounting for 83.4% of all the diagnosis. The primary diagnosis included 18 categories, the top 5 were circulatory system diseases, neoplasms, digestive system diseases, respiratory system diseases, and nervous system diseases, accounting for 68.6% of all the elderly inpatients. d) In the circulatory system diseases, the top 5 diseases were cerebral infarction, occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction, angina pectoris, acute myocardial infarction, atherosclerosis, chronic ischaemic heart disease, accounting for 69.8% of all the circulatory system diseases patients. Diseases in different age and gender group were cerebral infarction, angina, acute myocardial infarction, and chronic ischemic heart disease (Plt;0.05). Conclusion The disease constitution of the Xuanwu Hospital, Capital Medical University is complex, and the primary diagnosis is mainly circulatory system diseases. It can be concluded that in the following studies attention should be paid to drug utilization of circulatory system diseases, so as to provide evidence for making the China specific potentially inappropriate medicine list and disease prevention for the elderly.
Objective To investigate the effect of ischemic preconditioning(IPC) on myocardial ischemic reperfusion injury(I/R) of elderly rats. Methods Fiftysix Wistar rats, of which there were 28 aged from 21-23months(elderly rat) and 28 aged from 4-5months(young rat), were used to build isolated heart perfusion Langendorff model. The rats were divided into 7 groups with random number table（8 in each group）: adult control group, adult I/R group, adult IPC group, elderly control group, elderly I/R group, elderly IPC group and elderly enhanced IPC group. The control group underwent a 90-min perfusion without any intervention; the I/R group underwent a 30-min equilibration period, then a 30-min ischemia and a 30-min reperfusion; the IPC group underwent a 10-min equilibration period, then a 5-min ischemia for twice and a 5-min reperfusion, after that a 30-min ischemia and [CM(158-3mm]a 30-min reperfusion; the enhanced IPC group underwent a 10-min equilibration period, then a 5-min ischemia for 4-times and a 5-min reperfusion, after that a 30-min ischemia and a 30-min reperfusion. The recovery rates of cardiac output(CO), left ventricular developed pressure (LVDP), the maximum rising and descending rate of left ventricular pressure (±dp/dtmax) after a 30-min reperfusion were compared among groups. The activity of creatine kinase (CK) in coronary outflow, the level of malonyldialdehyde (MDA) and superoxide dismutase (SOD) before ischemia and after a 30min reperfusion were detected. The myocardial infarction areas were compared among groups. Results After a 30min reperfusion, compared with adult I/R group, in adult IPC group CK reduced significantly(89.48±18.72 U/L vs. 115.76±16.72 U/L，q=6.061，Plt;0.01)，the level of MDA decreased significantly（9.53±3.44 nmol/ml vs. 16.84±2.29 nmol/ml，q=7.732，Plt;0.01)，the level of SOD increased significantly（584.7±122.62 U/ml vs. 429.46±85.24 U/ml，q=4.754，Plt;0.01)，the recovery rates of CO,LVDP,+dp/dtmax and -dp/dtmax increased ignificantly(78.69%±9.68% vs. 65.10%±8.63%，83.61%±8.46% vs. 67.23±8.68%，81.68±8.68% vs. 67.89%±6.89%，89.79%±7.78% vs. 66.79%±8.46%，Plt;0.01), the myocardial infarction areas reduced significantly (5.25%±4.33% vs. 14.75%±8.02%,q=7.458，Plt;0.01)。There was no statistical significance between elderly IPC group and elderly I/R group in the above indexes（Pgt;0.05）.However, There was statistical significances between elderly enhanced IPC group and I/R group. CK reduced significantly (88.60±28.32 U/L vs. 105.76±9.64 U/L，q=5.620，Plt;0.01)，the level of MDA decreased significantly（8.38±3.36 nmol/ml vs. 16.80±3.06 nmol/ml，q=7.500，Plt;0.01)，the level of SOD increased significantly（558.87±78.66 U/ml vs. 433.75±86.65 U/ml，q=7.335，Plt;0.01)，the recovery rates of CO,LVDP,+dp/dtmax and -dp/dtmax increased significantly (77.99%±10.02% vs. 66.26%±9.78%，85.59%±6.67% vs. 73.90%±6.66%，83.87%±9.98% vs. 68.90%±8.68%，86.01%±766% vs. 70.39%±7.98%，Plt;0.01)， the myocardial infarction areas reduced significantly (795%±6.32% vs. 1568%±10.36%,q=8.680， Plt;0.01). 〖WTHZ〗Conclusion The protective effect of IPC on I/R elderly rat hearts has weakened. The enhanced IPC is able to regain the protective effect of IPC on elderly rat hearts.
ObjectiveTo explore the clinical outcomes of open reduction and internal fixation by posterolateral and posteromedial approaches for treating posterior Pilon fractures in elderly patients.
MethodsBetween August 2009 and August 2014, 20 elderly patients with posterior Pilon fractures were treated with open reduction and internal fixation by posterolateral and posteromedial approaches. There were 14 males and 6 females, aged from 66 to 83 years (mean, 72.7 years). The causes were falling injury in 11 cases and traffic accident injury in 9 cases. All the patients had lateral malleolus and medial malleolus fractures. The time from injury to operation was 7-14 days (mean, 8.6 days). The posterolateral incision was made to expose the posterolateral bone fragments of posterior malleolus and lateral malleolus fracture, and the posteromedial incision was made to expose the posteromedial fracture fragments of posterior malleolus and medial malleolus fracture. After reduction, fracture was fixed with locking plate or cannulated screw. All the patients began to functional exercise at 1 day after operation.
ResultsThe operation time was 60-110 minutes (mean, 92 minutes). The incisions healed primarily in all patients. There were no complications of incision dehiscence, infection, implant exposure, and nerve damage. No irritation sign of tendon was observed. All 20 cases were followed up for 12-18 months (mean, 13 months). The X-ray films showed that fracture healed at 3-9 months, with an average of 5.2 months. During follow-up period, no loosening or breakage of the implant was observed. The other patients could walk normally except 2 patients (over 80 years old) who could walk with crutch. According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the results were excellent in 12 cases, good in 4 cases, and fair in 4 cases; the excellent and good rate was 80%.
ConclusionA combination of posterolateral approach and posteromedial approach for open reduction and fixation of posterior Pilon fractures can achieve satisfactory effect in elderly patients. It has the advantages of protecting ankle blood supply and avoiding the soft tissue necrosis and implants exposure.
Under the new era background of actively advocating the " active health” in the elderly, the prevention methods of falls not only include environmental modification, reasonable drugs, emotional support, disease prevention and control, etc., but exercise should also be integrated into them. Exercise training can significantly improve muscle strength, balance, and mobility in the elderly, thereby reducing the risk of falls. This paper reviews the biomechanical causes of falls in the elderly, the sports training prescriptions for fall prevention in the elderly, and the research prospects of sports training for fall prevention in the elderly. It is hoped that the elderly population could establish an active healthy lifestyle based on sports training, elevate the physical fitness continuously, reduce the fall injury, and improve the quality of life through strength, balance, and endurance training.
Objective To discuss the relationship between recovery of anatomical integrity and functional outcome in elderly patients with distal radius fractures by comparing the effects of open reduction and closed reduction. Methods The cl inical data were retrospectively analyzed from 78 elderly patients with distal radius fractures treating with nonoperation andoperation from February 2005 to March 2009. Thirty-seven patients underwent closed reduction and spl intlet fixation or cast appl ication (non-operation group), and forty-one patients underwent open reduction and internal fixation (operation group). In non-operation group, there were 15 males and 22 females with an average age of 73 years (60-83 years). According to the AO classification system for fracture, there were 8 cases of type A2, 7 cases of type A3, 7 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1, 2 cases of type C2, and 3 cases of type C3. The time from injury to admission was between 30 minutes and 3 days with a mean time of 1 day. In operation group, there were 18 males and 23 females with an average age of 71 years (62-80 years). According to the AO classification system for fracture, there were 5 cases of type A2, 7 cases of type A3, 7 cases of type B1, 6 cases of type B2, 3 cases of type B3, 4 cases of type C1, 5 cases of type C2, and 4 cases of type C3. The time from injury to admission was between 30 minutes and 7 days with a mean time of 1 day. There were no significant differences (P gt; 0.05) in sex, age, disease course and fracture classification between two groups. Results All incisions obtained heal ing by first intention after operation in operation group. All patients were followed up for 9-36 months (20 months on average). Fracture heal ing was achieved within 8 to 15 weeks, with an average of 11 weeks. There were no significant differences (P gt; 0.05) in fracture heal ing time between non-operation group [(10.8 ± 2.0) weeks] and operation group [(11.7 ± 2.5) weeks]. At last follow-up, thepalmar tilt angle was (5.6 ± 2.0)° and (8.6 ± 3.0)°, the radial incl ination angle was (19.1 ± 4.9)° and (21.8 ± 2.0)°, and the radial length was (8.3 ± 1.3) mm and (10.4 ± 1.4) mm in non-operation group and operation group, respectively; showing significant differences (P lt; 0.05) between two groups. According to the Gartland-Werley score, the results were excellent in 9 cases, good in 21 cases, fair in 5 cases, and poor in 2 cases in non-operation group, the excellent and good rate was 81.1%; in operation group, the results were excellent in 13 cases, good in 25 cases, fair in 2 cases, and poor in 1 case, the excellent and good rate was 92.7%, showing no significant difference (P gt; 0.05) between two groups. There were no significant differences (P gt; 0.05) in flexion and extension activity of wrist, radioulnar partial activity, pronation-supination activity, grip and pinch strength between two groups. Conclusion Open reduction and closed reduction can achieve satisfactory functional outcomes, but closed reduction was inferior to open reduction in anatomic reduction for treating distal radius fractures in elderly patients.
Abstract: Objective To determine the effects of early enteral nutrition (EEN) on postoperative recovery in elderly patients with esophageal cancer. Methods We included 100 elderly patients with esophageal cancer who were admitted at the PLA 100 Hospital between January 2006 and April 2010, and whose diagnoses were confirmed by pathological examination. The patients were divided into an early enteral nutrition (EEN) group and a parenteral nutrition (PN) group, with 50 patients in each group. There were 32 males and 18 females with an average age of 72 years in the EEN group. There were 30 males and 20 females with an average age of 69 years in the PN group. We analyzed the effect of the nutrition administration method on bowel function recovery, hospital stay, complication rate, and nutritional status one week after surgery. Results The anal exhaust time (45.3±12.7 h vs. 73.6±11.7 h), time until anal defecation (80.5 h±15.6 h vs. 140.1±13.2 h), and hospital stay (13.0±1.8 d vs. 15.2±3.3 d) in the EEN group were all shorter than those in the PN group (Plt;0.05). The rates of lung infection, anastomotic leakage, and cardiac complications in the EEN group were significantly lower than those of the PN group (Plt;0.05). One week after the operation, the serum albumin (ALB), peripheral blood lymphocytes, transferrin, and 24 h urea nitrogen (BUN) in the EEN group were higher than those in the PN group (Plt;0.05). Conclusion Compared with parenteral nutrition, enteral nutrition can promote metabolic function in elderly patients after recovery, reduce morbidity, and promote recovery.
Objective To explore the relationship between different diagnostic criteria (ATPIII2002, IDF2005 and CDS2007 criteria) for metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD). Methods A total of 666 elderly males admitted to West China Hospital for routine physical examination were involved in this study in May, 2010. The diagnostic agreement rates of different criteria were compared, along with the relationship between different diagnostic criteria for MS and NALFD. Results The diagnostic agreement of CDS2007 criteria with either IDF2005 or ATPIII2002 criteria was good. However, the agreement of ATPIII2002 with IDF2005 was compromised. The prevalence of NAFLD in MS group was significantly higher than that of non-MS group (Plt;0.01). On the basis of CDS2007 criteria, there was significant correlation between NAFLD and MS (Plt;0.000). Conclusion There is a close relation between NAFLD and all three diagnostic criteria of MS. NAFLD is one of the most important risk factors of MS. The diagnostic agreement of CDS2007 criteria with the other two is good, and there is significant correlation between NAFLD and criteria CDS2007 of MS. CDS2007 is found to be of high accuracy and applicability in the diagnosis of MS in Chinese population including the elderly.
ObjectiveTo discuss the clinical characteristics of liver cirrhosis in elderly patients.
MethodsWe retrospectively analyzed the clinical data of 67 patients (elderly group) with liver cirrhosis aged ≥60 treated between January 1998 and December 2010. Then, we compared these cases with another 72 liver cirrhosis patients (non-elderly group) aged<60.
ResultsThe incidence of jaundice, ascites and albumin deficiency in the elderly patients was significantly higher than that in the non-elderly patients (P<0.05). Complications in the elderly group were relatively more, including electrolyte imbalance, infections, gastrointestinal bleeding, hepatic encephalopathy, liver cancer, liver and kidney syndrome and liver and lung syndrome, and the incidence of these complications was all significantly higher than the non-elderly group (P<0.05) except the liver and kidney syndrome (P>0.05). The causes of liver cirrhosis in both groups were similar. The most common cause was hepatitis B virus infection, followed by chronic alcoholism, but in the elderly group, chronic alcoholism, cholestasis, poisoning from medicines and poisons and liver blood circulation disorders were more common than the non-elderly group (P<0.05); hepatitis B and non-alcoholic fatty hepatitis were more common in the non-elderly group than in the elderly group (P<0.05). The elderly group had more Child-Pugh class C cases (P<0.05), while there were more class A cases in the non-elderly group (P<0.05). Twenty-six patients died in the elderly group with a mortality rate of 38.8%; while only 13 died in the non-elderly group with a mortality rate of 18.1%. The difference of mortality rate was significant between the two groups (P<0.05). Common causes of death in the elderly group were infection, hepatic encephalopathy, and electrolyte disorders and gastrointestinal bleeding, while the common causes of death in the non-elderly group were gastrointestinal bleeding and electrolyte disorders.
ConclusionThe etiology, clinical manifestations and prognosis of liver cirrhosis in elderly patients differ from those in younger patients. We must pay more attention on treating complications of liver cirrhosis in elderly patients.
