RESUMO

Middle-aged and elderly patients with femoral neck fracture often suffer from basic diseases. Conservative treatment will significantly increase the incidence of complications. At present, surgical treatment is mostly advocated. Internal fixation is one of the effective treatment methods for middle-aged and elderly patients with femoral neck fracture. It has the advantages of improving hip joint function, accelerating patient recovery, and improving patient quality of life. At present, there are many choices of internal fixation in the world, each has its own advantages and disadvantages, and there is no unified standard. Different surgical methods can be selected according to various factors such as fracture type, patient′s physical condition and surgical auxiliary technology. This article reviews the clinical progress of internal fixation for femoral neck fractures in middle-aged and elderly patients from four aspects: the characteristics of femoral neck fractures in middle-aged and elderly patients, common internal fixation methods, 3D printing guide plate auxiliary technology and artificial intelligence auxiliary technology.

RESUMO

Objective:To investigate the current situation of geriatric nursing ability of clinical nursing teachers and analyze the influencing factors, and to identify demands of geriatric nursing training.Methods:From May to June 2023, a cross-sectional study was conducted among 2 408 clinical nursing teachers in 50 tertiary hospitals from 9 provinces and cities in East China, South China, Central China, North China, and Southwest China using the general information questionnaire, Geriatric Nursing Competence Scale for Clinical Nurses, and Geriatric Nursing Training Demands Questionnaire.Results:Among the clinical nursing teachers surveyed, there were 269 (11.17%), 938 (38.95%), and 1 201 (49.88%) teachers at low, medium, and high levels of geriatric nursing ability, respectively. The results of multinomial Logistic regression analysis showed that age, years of working in geriatric nursing, geriatric nursing related training, satisfaction with clinical nursing work, and interest in geriatric nursing work were common influencing factors in the low and medium level groups ( P<0.05), and professional title was a specific influencing factor in the medium level group ( P<0.05). The top three demands of geriatric nursing training content were geriatric nursing service model, knowledge of chronic disease management, and comprehensive geriatric assessment techniques. The top three demands of training forms were live streaming, field visits, and offline lectures. Conclusions:For clinical nursing teachers, demand-oriented geriatric nursing training should be strengthened, and attention should be paid to the satisfaction and interest in nursing work, so as to improve the teachers' geriatric nursing ability and strengthen the level of geriatric service.

RESUMO

Objective:To investigate the efficacy of double S-shaped elastic stable intramedullary nailing in the treatment of paediatric fractures of the distal tibia diaphyseal metaphyseal junction.Methods:From January 2018 to January 2022, a total of 25 children with fracture of the distal tibia diaphyseal metaphyseal junction were treated at Department of Pediatric Orthopedics, The Second Affiliated Hospital of Inner Mongolia Medical University. All of them were treated with closed reduction and double S-shaped elastic stable intramedullary nailing. There were 16 males and 9 females with an average age of (10.4±3.3) years, and 14 left sides and 11 right sides. The operation time, imaging results and complications were recorded after operation. At the last follow-up, the American Orthopaedic Foot & Ankle Society (AOFAS) scoring was used to evaluate the efficacy.Results:Closed reduction succeeded in all patients. The operation time was (55.6±23.7) min. Follow-up lasted (20.5±4.7) months for this cohort. Bony union was achieved in all patients after (11.5±2.7) weeks. No postoperative complications occurred in the patients, like infection, loss of reduction, disparity in length of lower limbs, delayed union or non-union. The AOFAS scoring at the last follow-up yielded 23 excellent and 2 good cases, and an excellent and good rate of 100% (25/25).Conclusion:In the treatment of paediatric fractures of the distal tibia diaphyseal metaphyseal junction, double S-shaped elastic stable intramedullary nailing is a safe, effective and feasible option.

RESUMO

@#Objective     To investigate the accuracy of 18F-FDG positron emission tomography/computed tomography (PET/CT) combined with CT three-dimensional reconstruction (CT-3D) in the differential diagnosis of benign and malignant pulmonary nodules. Methods     The clinical data of patients who underwent pulmonary nodule surgery in the Department of Thoracic Surgery, Northern Jiangsu People's Hospital from July 2020 to August 2021 were retrospectively analyzed. The preoperative 18F-FDG PET/CT and chest enhanced CT-3D and other imaging data were extracted. The parameters with diagnostic significance were screened by the area under the receiver operating characteristic (ROC) curve (AUC). Three prediction models, including PET/CT prediction model (MOD PET), CT-3D prediction model (MOD CT-3D), and PET/CT combined CT-3D prediction model (MOD combination), were established through binary logistic regression, and the diagnostic performance of the models were validated by ROC curve. Results     A total of 125 patients were enrolled, including 57 males and 68 females, with an average age of 61.16±8.57 years. There were 46 patients with benign nodules, and 79 patients with malignant nodules. A total of 2 PET/CT parameters and 5 CT-3D parameters were extracted. Two PET/CT parameters, SUVmax≥1.5 (AUC=0.688) and abnormal uptake of hilar/mediastinal lymph node metabolism (AUC=0.671), were included in the regression model. Among the CT-3D parameters, CT value histogram peaks (AUC=0.694) and CT-3D morphology (AUC=0.652) were included in the regression model. Finally, the AUC of the MOD PET was verified to be 0.738 [95%CI (0.651, 0.824)], the sensitivity was 74.7%, and the specificity was 60.9%; the AUC of the MOD CT-3D was 0.762 [95%CI (0.677, 0.848)], the sensitivity was 51.9%, and the specificity was 87.0%; the AUC of the MOD combination was 0.857 [95%CI (0.789, 0.925)], the sensitivity was 77.2%, the specificity was 82.6%, and the differences were statistically significant (P<0.001). Conclusion     18F-FDG PET/CT combined with CT-3D can improve the diagnostic performance of pulmonary nodules, and its specificity and sensitivity are better than those of single imaging diagnosis method. The combined prediction model is of great significance for the selection of surgical timing and surgical methods for pulmonary nodules, and provides a theoretical basis for the application of artificial intelligence in the pulmonary nodule diagnosis.

RESUMO

Objective:To investigate the clinical efficacy of butylphthalide combined with hyperbaric oxygen therapy on post-stroke cognitive impairment in patients with acute ischemic stroke.Methods:A total of 90 patients with post-stroke cognitive impairment who were hospitalized within 72 hours of onset in Suining County People's Hospital from December 2019 to November 2020 were included in this study. They were randomly divided into a control group and an observation group ( n = 45/group). The control group was given conventional treatment and the observation group was given butylphthalide combined with hyperbaric oxygen therapy in addition to conventional treatment. The National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score were compared between the two groups before and after treatment. Results:Before treatment, there were no significant differences in the National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score between the two groups (all P > 0.05). At 14 days and 1 month after surgery, the National Institutes of Health Stroke Scale scores in the observation group were (4.02 ± 2.18) points and (3.21 ± 2.03) points, which were significantly lower than (5.21 ± 2.24) points and (4.62 ± 2.68) points in the control group ( t =2.55, 2.81, both P < 0.05). At 1 and 3 months after treatment, the Montreal Cognitive Assessment score in the observation group were (19.79 ± 5.67) points and (23.69 ± 2.67) points, which were significantly higher than (16.88 ± 5.12) points and (19.74 ± 2.29) points in the control group ( t = 2.56, 7.53, both P < 0.05). At 1 and 3 months after treatment, Activities of Daily Living scores in the observation group were (54.85 ± 5.69) points and (74.38 ± 4.98) points, which were significantly higher than (46.78 ± 6.24) points and (63.21 ± 5.24) points in the control group ( t = 6.41, 9.76, both P < 0.05). Conclusion:Butylphthalide combined with hyperbaric oxygen therapy for the treatment of post-stroke cognitive impairment in patients with acute ischemic stroke can alleviate neurologic deficits, and improve cognitive function and the ability of daily life.

RESUMO

Objective:To explore the interaction effectiveness of residence and social support on physical function for older adults.Methods:Using multistage sampling method, the older adults in 9 provinces were chosen to investigate from January 2022 to January 2023 by using general information questionnaire and Short Physical Performance Battery.Binary Logistic regression analysis was used to explore the independent effectiveness of social support and residence category on physical function.The additive and multiplicative models were used to analyze the interactions between above two factors.Results:A total of 23 922 older adults were investigated.And 18 719(78.3%)older adults had poor physical function.There were significant independent effect of social support and residence category on physical function of older adults( P<0.001). Besides, the results showed that residence category and social support had a significant multiplicative interaction on physical function( OR=0.763, 95% CI: 0.615-0.947, P=0.014). The crossover analysis showed that older adults living in rural as well as lack of social support had the highest probability of impaired physical function( OR=1.521, 95% CI: 1.308-1.769, P<0.001). But there was no difference found in additive interaction. Conclusions:An interaction effect was found in rural living and lack of social support.Older adults living in rural as well as lack of social support have a higher risk of impaired physical function.

RESUMO

Objective:To explore the predictive value of psoas muscle index(PMI)on early survival and complications after liver transplantation(LT)in children with biliary atresia(BA).Methods:Between January 1, 2016 and September 30, 2020, the relevant clinical data are retrospectively reviewed for 244 BA children undergoing LT at Department of Pediatric Liver Transplantation, Tianjin First Central Hospital.Total psoas muscle area(PMA)at the level of the third lumbar endplate is measured based upon preoperative abdominal computed tomography(CT)and normalized by the square of length for obtaining the value of PMI.According to the survival at Year 1 post-LT, receiver operating characteristic(ROC)curve is plotted and the cut-off value calculated.According to the cut-off value, they are divided into two groups of high PMI(173 cases)and low PMI(71 cases). Then the clinical data of 2 groups are compared.Kaplan-Meier survival curves at Year 1 post-LT are analyzed.And Cox proportional hazard model is utilized for conducting a multivariate analysis of early death.Results:The cut-off value of PMI is 534.6 mm 2/m 2.Two groups are compared in terms of age, gender, weight-for-age Z-score(WAZ), length-for-age Z-score(LAZ)and preoperative laboratory parameters ( P>0.05). Significant inter-group differences existed in the types of donors and surgery( P<0.05), and the median age of recipients in low PMI is higher than high PMI group(7.77months vs 6.57 months, P<0.01). The proportion of children with a history of Kasai surgery in low PMI group(78.87% vs 53.76%, P<0.01)and the median length of stay in hospital(23 d vs 20 d, P=0.03)is higher in low PMI group, but recipients(88.7% vs 97.1%, P<0.01)and grafts(87.3% vs 96%, P=0.01)1-year survival rate are lower.Multivariate analysis indicated that high PMI is a protective factor for early postoperative survival( HR=0.132, 95% CI: 0.028~0.626, P=0.011). Conclusions:PMI is an independent predictor of early survival post-LT and has a certain predictive value for early graft loss in BA children.

RESUMO

Objective:To compare the efficacies of arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement in the treatment of chronic lateral ankle instability (CLAI) concomitant with fibular tendinitis.Methods:A retrospective cohort analysis was conducted on the clinical data of 31 patients with CLAI concomitant with fibular tendinitis, who were treated in Beijing Tongren Hospital, Capital Medical University between March 2019 and December 2021. The patients included 17 males and 14 females, aged 16-57 years [(32.8±9.6)years]. The anterior drawer test and talar tilt test were positive in all patients preoperatively. Diagnosis was confirmed by physical examination and MRI, and calcaneofibular ligament rupture was excluded. Eleven patients received arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement (modified Brostr?m procedure+tendon debridement group), and 20 underwent pure arthroscopic modified Brostr?m procedure (modified Brostr?m procedure group). The operation time, intraoperative blood loss and length of hospital stay were documented. The visual analogue score (VAS) in peroneal tendon area was assessed before operation and at postoperative 2, 6 and 12 weeks. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and foot and ankle outcome score (FAOS) were assessed before operation and at postoperative 6 and 12 weeks. The anterior drawer test was performed at the last follow-up. The foot and ankle ability measure (FAAM) score was assessed before operation and at the last follow-up. Postoperative wound healing and complications were also observed.Results:All the patients were followed up for 4-19 months [(11.3±3.5)months]. The operation time was (66.0±4.2)minutes in the modified Brostr?m procedure+tendon debridement group, which was significantly longer than (61.5±3.4)minutes in the modified Brostr?m procedure group ( P<0.05). There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups (all P>0.05). Compared with the preoperation, the value of VAS was significantly lowered, and the values of AOFAS ankle-hindfoot score, FAOS and FAAM score were significantly increased at different postoperative timepoints (all P<0.01). No significant differences in the values of VAS, AOFAS ankle-hindfoot score, FAOS or FAAM score were seen between the two groups before operation (all P>0.05). The value of VAS was 3.0(3.0, 4.0) points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 4.0(4.0, 4.0)points in the modified Brostr?m procedure group at 2 weeks postoperatively ( P<0.05). The value of VAS was 2.0(1.0, 3.0)points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 3.0(2.3, 3.0)points in the modified Brostr?m procedure group at 6 weeks postoperatively ( P<0.05). At 12 weeks postoperatively, there was no significant difference in the value of VAS between the two groups ( P>0.05). There were no significant differences in the values of AOFAS ankle-hindfoot score and FAOS between the two groups at 6 or 12 weeks postoperatively (all P>0.05). The anterior drawer test was negative in all patients at the last follow-up. No significant difference was seen in the value of FAAM score between the two groups at the last follow-up ( P>0.05). All incisions were healed well in the first stage after operation, without the occurrence of joint infection, impaired joint motion, nerve injury or deep vein thrombosis. Conclusions:Arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement can both improve the foot function in CLAI patients concomitant with fibular tendinitis. However, the combined treatment allows for early pain relief, without increasing the risk of complications, and can therefore contribute to a faster postoperative recovery.

RESUMO

Objective:To investigate the treatment strategy for pediatric humeral supracondylar fractures with callus formation and displacement neglected for over 1 week.Methods:A retrospective analysis was made of the clinical data of 36 children who had been treated at Department of Pediatric Orthopaedics, Medical Center, The Second Affiliated Hospital, Inner Mongolia Medical University from January 2011 to January 2021 for humeral supracondylar fractures with callus formation and displacement neglected for over 1 week. There were 22 boys and 14 girls, with an age of (6.7±2.7) years (from 2.3 to 12.8 years). All fractures were Gartland type Ⅲ. The patients were divided into 2 groups according to their treatment methods: a closed reduction and percutaneous pinning (CRPP) group of 15 patients subjected to the CRPP treatment only, and a leverage group of 21 patients subjected to CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling. The 2 groups were compared in terms of operation time, fluoroscopy frequency, quality of reduction, and recovery time for elbow range of motion; the elbow range of motion, visual analogue scale (VAS), Mayo elbow performance score (MEPS) and complications were assessed at the last follow-up.Results:The 2 groups were comparable because there was no significant difference between them in the general information before operation ( P>0.05). All patients were followed up for (26.2±16.3) months (from 6 to 96 months). All the fractures obtained acceptable reduction and clinical union 4 to 6 weeks after operation. The operation time [(28.2±6.8) min] and fluoroscopy frequency [(27.0±6.0) times] in the leverage group were significantly less than those in the CRPP group [(40.8±10.8) min and (43.3±11.4) times] ( P<0.05). The CRPP group was significantly better than the leverage group in the intraoperative Baumann angle (78.1°±1.6° versus 73.7°±4.1°), lateral capitellohumeral angle (58.3°±2.6° versus 49.6°±5.2°) and horizontal rotation rate (109.5%±3.0% versus 103.2%±4.9%) ( P<0.05). The intraoperative reduction in the CRPP group was significantly closer to the normal mean value than that in the leverage group ( P<0.05). There was no significant difference in the recovery time for elbow range of motion between the CRPP and the leverage groups ( P>0.05). At the last follow-up, the Baumann angle (75.4°±2.8°) and the lateral capitellohumeral angle (53.2°±3.6°) in the leverage group were still significantly better than those in the CRPP group (78.3°±1.5° and 57.5°±2.3°) ( P<0.05). However, there was no significant difference in the elbow range of motion, VAS, MEPS or incidence of complications between the 2 groups ( P>0.05). Conclusion:To treat humeral supracondylar fractures with callus formation and displacement neglected for over 1 week in children, CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling is an efficient and accurate method, because it can lead to more satisfactory reduction than CRPP only.

RESUMO

Objective:To analyze the frequency and characteristics of polymyositis (PM) in idiopathic inflammatory myopathy (IIM), and to investigate whether PM is over-diagnosed.Methods:Patients diagnosed as IIM according to the Bohan & Peter criteria of IIM hospitalized in the Department of Rheumatology of China-Japan Friendship Hospital from 2008 to 2019 were involved in the study. Definite PM (dPM) was defined as typical clinical and pathological features including elevated creatine kinase (CK) level, muscle weakness and muscle biopsy findings with endomysial CD8 + T cell infiltration and expression of MHC-1 on sarcolemma. Meanwhile, dermatomyositis (DM), anti-synthase syndrome(ASS), immune-mediated necrotic myopathy(IMNM), sporadic inclusion body myositis(sIBM) and other myopathies were excluded according to the new classification criteria of IIM subtypes respectively. Statistical analysis was performed using SPSS software 24.0. The Kruskal-Wallis test and χ2 test were used to compare the clinical characteristics between the dPM group and other IIM subtypes. Results:A total of 1 259 patients with IIM including 1 015 (80.6%) DM and 244(19.4%) PM were enrolled in this study. According to the strict definition of PM criteria, only 0.5% of patients (6/1 259) in IIM could be diagnosed as dPM. Most PM patients were IMNM and ASS according to the new IIM subtypes criteria, of which 48.0% (117/244) were IMNM and 32.0% (78/244) were ASS. 66.7%(4/6) of dPM patients were women. One complicated with RA, and one was dPM overlaped with systemic sclerosis. All of them had muscle weakness, mild elevation of CK level [611(391,1 451) U/L], and were myositis-specific autoantibodies negative. Except one dPM patients who did not receive immunoregulatory therapy due to chronic obstructive pulmonary disease, the others were administrated with low or medium dose prednisone combined with or without immunosuppressive agents. After a median follow-up of (38±26) months, the muscle strength of dPM patients were improved.Conclusion:dPM is a very rare clinical subtype of IIM. PM is an over-diagnosed entity in clinical practice. Patients with dPM have mild symptoms and good outcome.

RESUMO

Objective:To explore the relationship and underlying mechanism between exosomes derived from doxorubicin-resistant osteosarcoma cells and MDR1 and miRNAs. Methods:MG63 and U2OS cell lines were selected to construct doxorubicin-resistant strains, and the 50% inhibitory concentration (half maximal inhibitory concentration, IC 50) of drug-resistant and sensitive strains was detected by MTT, and fluorescence staining was performed at intervals of 15 min between 15 and 120 min to detect the change of fluorescence intensity. RT-PCR and Western Blot were used to detect the expression levels of MDR1 P-gp to verify the drug resistance of osteosarcoma cells. Exosomes were identified by particle size analysis and Western Bolt detection. The endocytosis of PKH26-labeled exosomes from doxorubicin-resistant cells was observed, and the proliferation level and migration of exosomes from doxorubicin-resistant cells co-cultured with osteosarcoma cells were detected by MTT assay and cell scratch assay. The differential expression levels of miRNAs in osteosarcoma-sensitive and drug-resistant cells were verified by sequencing and bioinformatics analysis and RT-PCR assay. Tumor growth, serum exosome identification and mRNA expression level of miR-21-5p in tumor-bearing nude mice between normal osteosarcoma cell group and drug-resistant group, drug-resistant+normal exosome group, drug-resistant+drug-resistant+drug-resistant exosome group were observed. MDR1 expression level in tumor tissue was detected by RT-PCR, Western Blot and immunohistochemistry. Results:The IC 50 of two adriamycin resistant strains were 2.21 vs. 11.81 μg/ml and 0.93 vs. 11.81 μg/ml, respectively, and the fluorescence intensity decreased faster than that of normal strains. The relative mRNA expression levels of MDR1 in two cell lines were normal 1.12±0.16, 1.02±0.11 and drug-resistant 2.15±0.10, 2.127±0.12, respectively. The relative protein expression of P-gp was normal 0.92±0.11, 0.73±0.10 and drug-resistant 0.46±0.03, 0.30±0.04, the differences were statistically significant ( P<0.05). Drug-resistant exosomes can enter osteosarcoma cells through endocytosis and concentrate in the cytoplasm when co-cultured with normal strains. Osteosarcoma cells were co-cultured with drug-resistant exosomes at 2, 4, 6, and 8 μg/ml adriamycin, respectively. Compared with normal group, the proliferation level in drug-resistant group was significantly increased. Compared with the normal cell group 35.95±3.92, 6.72±3.55 and the normal exosome group 51.22±5.55, 19.31±1.93, the drug-resistant cell group 54.20±9.32, 19.24±2.88 and drug-resistant exosome group 76.40±5.41, 30.26±4.87, all had significantly higher cell mobility, the difference was statistically significant ( P<0.05). Exosome sequencing and biogenic analysis of 10 highly upregated miRNAs to validate mRNA expression differences between normal and drug-resistant strains by RT-PCR, showing a significant increase in miR-21-5p expression level of drug-resistant strains (5.89±0.26 vs. 0.99±0.06; 1.05±0.07 vs. 8.80±0.93, P<0.05), the difference was statistically significant ( P<0.05). In MG63 and U2OS, the normal cell group and drug-resistant cell group, and the normal exosome group and drug-resistant exosome group were compared, the tumor volume and the terminal tumor weight of nude mice were increased to varying degrees. MRNA relative expression levels of miR-21-5p in serum exosomes of nude mice after drug intervention were 0.86±0.07 and 0.86±0.05 in normal cell group, respectively. The values were 1.13±0.12, 1.14±0.12 in drug-resistant cell group, 0.71±0.05, 0.75±0.03 in normal exosome group, and 0.90±0.07, 0.93±0.04 in drug-resistant exosome group. Compared with normal and drug-resistant strains, the expression levels of normal and drug-resistant exosome groups were increased, with statistical significance ( P<0.05). Conclusion:The exosomes of drug-resistant cells in osteosarcoma could enhance the proliferation level and migration ability of cells through intercellular transfer of MDR1 and miRNAs. The expression of MDR1 and miR-21-5p in drug-resistant cells and tumor-forming nude mouse serum and tumor tissues were up-regulated which suggested that it might be involved in regulating the drug resistance process of osteosarcoma.

RESUMO

Objective:To explore the effects of frailty syndrome on activities of daily living and its associated risk for adverse outcomes among elderly residents in China.Methods:Using open data from "China Health and Retirement Longitudinal Survey", the 2011 baseline survey was conducted on general information, health risk factors, chronic disease, data obtained from various ability assessments and Fried frailty criteria assessments for community elderly aged 60 years and over.The follow-up data were used to analyze the adverse outcomes of frailty syndrome using a covariation-adjusted Logistic regression model.Results:Among the 5 630 people in the baseline population, 34.9%(1 963/5 630 cases)were non-frailty, 57.4%(3 236 cases)were pre-frailty, and 7.7%(431 cases)were frailty.The frailty group had higher rates of falls, hip fractures, hospitalizations, and death than the pre-frail and non-frail groups at the 3rd, 5th, and 8th years of follow-up.At follow up to 2015, the covariate-adjusted analysis of the study population showed that as compared with the non-frail group, the frail group had increased risks of falling( OR=1.738, 95% CI: 1.292-2.338, P<0.001), increased risks of hip fracture( OR=2.672, 95% CI: 1.365-5.233, P=0.004), increased risks of hospitalization( OR=1.670, 95% CI: 1.224-2.277, P=0.001), increased risk of death( OR=1.599, 95% CI: 1.256-2.035, P<0.001), increased risks of declined upper limb activity( OR=2.769, 95% CI: 2.101-3.650, P<0.001), of declined instrumental activity of daily living( OR=2.567, 95% CI: 1.941-3.395, P<0.001), and of declined basic activities of daily living( OR=2.790, 95% CI: 2.110-3.689, P<0.001). Conclusions:Frailty syndrome increases the risk of decreased ability to live, falls, hip fractures, hospitalization and death in older adults.Frailty screening is an effective tool for predicting the risk of adverse outcomes in elderly community populations.
