Analysis of survival rate after hip fragility fracture in Tianjin Hospital from 2015 to 2021 / 中华骨科杂志

Objective:To analyze the change trend of survival rate after hip fragility fracture in Tianjin Hospital from 2015 to 2021, and the influence of gender, marital status, age and number of complications on survival rate.Methods:From January 1, 2015 to December 31, 2021, a total of 12,570 patients with fragility fracture of hip were retrieved, including 3,934 males and 8,636 females. The age at admission was 74.11±9.50 years and 74.62±8.99 years respectively. By comparing the ID number with the Tianjin population information database, 2,054 cases died, including 804 males and 1,250 females, aged 81.34±7.88 years and 81.92±7.42 years respectively at the time of death. Acquire the patient's survival status, calculate the cumulative survival rate at 3 month intervals, study the change rule of the cumulative survival rate over time, and use Kaplan-Meier method to calculate the cumulative survival rate of the whole population and the impact of gender, marital status, age, and number of complications on the survival rate.Results:The median survival time of all the dead people after fracture was 13(3, 31) months, including 11(2, 27) months for males and 15(4, 32) months for females. Joinpoint regression showed that 9 months after the hip fragility fracture was the break point of the survival rate. The mortality rate changed significantly within 9 months after fracture (the annual change rate was 47%), and slowed down 9 months later (the annual change rate was 1%). There was a statistically significant difference in trend detection before and after the break point ( P<0.05). The age at admission was 80.11±7.71 years for the dead and 73.36±9.01 years for the non dead, with a statistically significant difference ( t=31.80, P<0.001). After normalization, the number of complications was 0.20±0.93 among the dead and 0.00±0.87 among the non dead, with a statistically significant difference ( t=88.81, P<0.001). The survival rate of men after hip fracture is lower than that of women, the number of people without spouse is lower than that of people with spouse, the number of people with more than 70 years old is lower than that of people with less than 70 years old, and the number of complications ≥2 people is lower than that of people with less than 1 complication, all of which are statistically significant ( P<0.05). Conclusion:The survival rate within 9 months after the occurrence of hip fragility fracture decreased significantly, and it needs to be tracked and managed for at least 9 months to effectively reduce the risk of death; Male, no spouse, age>70 years old, number of complications ≥2 will increase the risk of death after hip fragility fracture, leading to reduced survival rate of patients.

Analysis on influencing factors of perioperative nosocomial infection in elderly patients with hip fracture under the background of enhance recovery after surgery / 中国实用护理杂志

Objective:To analyze the influencing factors of perioperative nosocomial infection in elderly patients with hip fracture under the background of enhance recovery after surgery so as to provide guidance for prevention and control of the nosocomial infection.Methods:The clinical data were collected from 1 628 elderly patients with hip fracture who were hospitalized from January 2018 to August 2019,during the implementation of enhance recovery after surgery in Tianjin hospital. Medical records of the patients were reviewed and statistically analyzed through hospital medical record system, the incidence of perioperative nosocomial infection and the influencing factors for the infection were observed.Results:Of the 1 628 hospitalized patients with hip fracture, 102 had nosocomial infection, 125 case-times, with the infection rate 6.27%(102/1 628) and the case-times infection rate 7.68%(125/1 628). Lower respiratory tract, urinary tract and surgical site were the dominant infection sites, accounting for 72.80% (91/125), 11.20% (14/125) and 10.40% (13/125) respectively. Univariate analysis and multivariate logistic regression analysis indicated that bone traction( OR value was 2.152, 95% CI 1.130-4.097), surgery ( OR value was 0.268, 95% CI 0.133-0.537), hospitalization days≥15 d( OR value was 12.123, 95% CI 6.017-24.426), indwelling urinary catheter ( OR value was 7.566, 95% CI 4.093-13.986), cardiac insufficiency( OR value was 2.112, 95% CI 1.192-3.740), electrolyte disturbance( OR value was 2.383, 95% CI 1.396-4.067), lower extremity arteriosclerosis obliterans( OR value was 2.540, 95% CI 1.279-5.045) and senile dementia( OR value was 3.673, 95% CI 1.670-8.082) were the influencing factors for the perioperative nosocomial infection. Conclusions:The main influencing factors of nosocomial infection in elderly patients with hip fracture during the perioperative period were bone traction, operation, length of stay, indwelling urinary catheter and coexisting diseases. The risk of nosocomial infection can be reduced by applying the concept of enhance recovery after surgery in clinical orthopedics, comprehensively optimizing perioperative management and implementing effective prevention and control measures of nosocomial infection.

Research on care models of fragility fractures in the elderly / 中国实用护理杂志

The characteristics of the elderly patients with fragility fracture were analyzed, the concept of orthogeriatrics care was expounded, and the research progress of the care mode of the elderly patients with fragility fracture were summarized, so as to provide reference for the clinical practice of the elderly orthopedic department and the training of specialized nurses in China.

Progress in Cathepsin K Inhibitor Odanacatib / 天津医药

The prevalence of osteoporosis has increased during recent years. The activation in the function of osteo?clast is the main reason of osteoporosis. Cathepsin is expressed by osteoclast and involved in the degradation of collagen of bone,and causes osteoporosis. Cathepsin K is a kind of most important enzyme in the family of cathepsin. Odanacatib(ODN) is the inhibitor of cathepsin K, and it may be used to anti-osteoporosis thought inhibiting the degradation of bone collagen. It was found that the cortical thickness and bone minerals of cancellous increased after taking ODN in the studies, and then the density and the strength of bone increased. This study reviewed the pharmacological profile of ODN and the progresses of ani?mal study and clinical trials about ODN.

Dosage and safety of aspart insulin in continuous subcutaneous insulin infusion plus oral antidiabetic drugs for hyperglycemia in elderly patients with hip fractures / 中华老年医学杂志

Objective To investigate the dosage and safety of insulin aspart in continuous subcutaneous insulin infusion plus oral antidiabetic drugs for the treatment of hyperglycemia in elderly hip fracture.Methods Patients with hip fracture and hyperglycemia who required insulin pump therapy were divided into 2 groups according to age:elderly group (patients aged over 65 years,n=42) and non-elderly group (patients aged under 65 years,n=43).All patients were treated with insulin aspart in continuous subcutaneous insulin infusion plus oral antidiabetic drugs combined with diet therapy.Dosages of aspart insulin and adverse effects were compared between the two groups.Results There were no significant differences in basic aspart dosage and additional premeal dosage between elderly and non-elderly groups [(0.29±0.09) IU/kg vs.(0.30±0.07) IU /kg,(0.27±0.09) IU/kg vs.(0.27±0.07) IU/kg,both P＞0.05].The incidences of hypoglycemia with and without symptoms in elderly versus non-elderly groups were 4.8％ vs.4.7％ and 14.3％ vs.18.6％,which had no significant differences between the two groups (P＞0.05).Hypoglycemia accompanied by consciousness disorders,allergy,nonhealing and slow healing wounds were not found in the two groups.The ratio of oral antidiabetic drugs including metformin,glimepiride,and glycosidase inhibitor had no differences between the two groups.Conclusions Aspart insulin in continuous subcutaneous insulin infusion is effective and safe in the treatment of acute severe hyperglycemia in elderly patients with hip fractures when combined with diet therapy and oral antidiabetic drugs.
