What are the Risks of Death in Elderly Patients after a Proximal Femur Fracture at Aristide le Dantec Hospital?

Introduction: Proximal femur fractures are traumatic injuries involving the neck and trochanteric region of the femur. The aim was to identify risk factors for death following proximal femur fractures in elderly patients. Patients and methods: This was a prospective, observational, longitudinal study conducted over an 18-month period in the Orthopedics-Traumatology Department of Aristide Le Dantec Hospital in Dakar. We evaluated a total of 93 patients aged at least 60 years with a proximal femur fracture whose date of onset was less than 3 weeks. The identification of risk factors for death took into account socio-demographic, clinical and therapeutic parameters. Results: The number of patients who died was 19 (20.43%). There was no significant difference in mortality according to age, gender or residence. There was no association between admission time and mortality. The association between the number of comorbidities and mortality was significant. The association between mortality and ASA score and type of treatment was highly significant. Operating time had no influence on mortality. Type of anesthesia, on the other hand, did influence mortality. Conclusion: Mortality due to proximal femur fractures in the elderly remains high. In our practice, this mortality was related to the presence of comorbidity, impaired cognitive function, ASA score, type of treatment and type of anesthesia.

Correlation between anxiety, depression, and social stress in young patients with thoracolumbar spine fractures

BACKGROUND Traumatic injuries,such as falling,car accidents,and crushing mostly cause spinal fractures in young and middle-aged people,and>50%of them are thoracolumbar fractures.This kind of fracture is easily combined with serious injuries to peripheral nerves and soft tissues,which causes paralysis of the lower limbs if there is no timely rehabilitation treatment.Young patients with thoracolumbar fractures find it difficult to recover after the operation,and they are prone to depression,low self-esteem,and other negative emotions.AIM To investigate the association between anxiety,depression,and social stress in young patients with thoracolumbar spine fractures and the effect on rehabilitation outcomes.METHODS This study retrospectively analyzed 100 patients admitted to the orthopedic department of Honghui Hospital,Xi’an Jiaotong University who underwent thoracolumbar spine fracture surgery from January 2022 to June 2023.The general data of the patients were assessed with the Hamilton anxiety scale(HAMA),Hamilton depression scale(HAMD),life events scale,and social support rating scale(SSRS)to identify the correlation between anxiety,depression scores,and social stress and social support.The Japanese Orthopedic Association(JOA)was utilized to evaluate the rehabilitation outcomes of the patients and to analyze the effects of anxiety and depression scores on rehabilitation.RESULTS According to the scores of HAMD and HAMA in all patients,the prevalence of depression in patients was 39%(39/100),and the prevalence of anxiety was 49%(49/100).Patients were categorized into non-depression(n=61)and depression(n=39),non-anxiety(n=51),and anxiety(n=49)groups.Statistically significant differences in gender,occupation,Pittsburgh Sleep Quality Index(PSQI)score,and monthly family income were observed between the non-depression and depression groups(P<0.05).A significant difference in occupation and PSQI score was found between the non-anxiety and anxiety groups.Both depression(r=0.207,P=0.038)and anxiety scores(r=0.473,P<0.001)were significantly and positively correlated with negative life events.The difference in negative life event scores as well as SSRS total and item scores was statist-ically significant between patients in the non-depression and depression groups(P<0.05).The difference between the non-anxiety and anxiety groups was statistically significant(P<0.05)in the negative life event scores as well as the total SSRS scores.Additionally,JOA scores were significantly lower in both anxious and depressed patients.CONCLUSION Young patients with thoracolumbar fractures are prone to anxiety and depression.Patients’anxiety and depression are closely associated with social pressure,which reduces the life pressure of young patients with thoracolumbar fractures,enhances social support,and improves the psychology of anxiety and depression.,which affects patients’recovery.

Relationship between Natural Fracture and Structural Style and its Implication for Tight Gas Enrichment:A Case Study of Deep Ahe Formation in the Dibei–Tuzi Area,Kuqa Depression

The deep Lower Jurassic Ahe Formation(J_(1a))in the Dibei–Tuzi area of the Kuqa Depression has not been extensively explored because of the complex distribution of fractures.A study was conducted to investigate the relationship between the natural fracture distribution and structural style.The J_(1a)fractures in this area were mainly high-angle shear fractures.A backward thrust structure(BTS)is favorable for gas migration and accumulation,probably because natural fractures are more developed in the middle and upper parts of a thick competent layer.The opposing thrust structure(OTS)was strongly compressed,and the natural fractures in the middle and lower parts of the thick competent layer around the fault were more intense.The vertical fracture distribution in the thick competent layers of an imbricate-thrust structure(ITS)differs from that of BTS and OTS.The intensity of the fractures in the ITS anticline is similar to that in the BTS.Fracture density in monoclinic strata in a ITS is controlled by faulting.Overall,the structural style controls the configuration of faults and anticlines,and the stress on the competent layers,which significantly affects deep gas reservoir fractures.The enrichment of deep tight sandstone gas is likely controlled by two closely spaced faults and a fault-related anticline.

Factors influencing the continuity of evidence-based practice in perioperative airway management for elderly patients with fractures:A qualitative study

BACKGROUND More and more evidence-based practices are emerging,but researchers mostly focus on short-term effects,resulting in evidence-based practices not being applied in the clinic in the long term.In this study,we took the evidence-based practice of perioperative airway management in elderly fracture patients as an example and adopted a descriptive phenomenological approach to understand the influencing factors of its sustainability to provide a reference basis for promoting the continuity of evidence-based practice in the clinic.AIM To explore factors influencing the persistence of evidence-based practice in perioperative airway management in elderly patients with fractures.METHODS This study was qualitative research.Nine nurses who implemented evidencebased practice in the orthopedic ward of a tertiary comprehensive hospital in Shanghai from September 2023 to October 2023 were selected using purposive sampling as research subjects.Semi-structured interviews were conducted with them,and the data were analyzed using the Colaizzi phenomenological analysis method based on the three dimensions and ten factors of the NHS sustainability model.RESULTS Three main themes and ten subthemes were identified:Process aspects(benefits to patients,benefits to nurses,lack of follow-up,complex processes);staff aspects(insufficient human resources,inadequate training and education,lack of leadership support);and organizational environment aspects(inadequate infrastructure,poor patient compliance,poor doctor cooperation).CONCLUSION Human resources,training and education,leadership support,infrastructure,and patient-physician collaboration are important factors influencing the sustainability of evidence-based practice for perioperative airway management in older patients with fractures.

Hemiarthroplasty for irreparable distal radius fractures in the elderly:A comprehensive review

BACKGROUND Elderly patients maintaining functional independence can now be candidates for primary wrist hemiarthroplasty to manage acute irreparable distal radius fractures(DRFs).However,further investigation with long-term follow-up is required to validate these initial findings.AIM To review the literature on the outcomes of distal radius hemiarthroplasty with available implants to assess its viability as a treatment option.METHODS A comprehensive review of the literature was conducted using electronic databases,including PubMed,Medline,and Scopus.The search terms employed were"distal radius fracture","hemiarthroplasty","wrist arthroplasty",and related terminology.The search was restricted to articles published in English from 1980 until June 2023.Inclusion criteria encompassed cases or case series of DRF treated with hemiarthroplasty,providing clinical or radiographic outcomes,and published in peer-reviewed journals.RESULTS A total of 2508 articles from PubMed and 883 from Scopus were identified initially.Following screening and removal of duplicates,13 articles met the inclusion criteria.These articles,predominantly clinical retrospective studies,provided insights into hemiarthroplasty outcomes,including functional improvements and complications.Hemiarthroplasty was a treatment option for complex DRF,particularly those cases with severe comminution,intraarticular involvement,or severe osteoporosis.Functional outcomes demonstrated improvements in pain relief,wrist mobility,and grip strength,with variability across studies.Complications included implant loosening,infection,nerve injury,and stiffness,with varying incidence rates influenced by surgical techniques and implant choice.Long-term outcomes were inadequately documented,warranting further research.CONCLUSION Hemiarthroplasty is a promising treatment for irreparable DRF in the elderly.Long-term outcomes and complications require further study.

Influence of preoperative comprehensive education on anxiety,depression,pain,and sleep in elderly patients operated under general anesthesia

BACKGROUND Owing to the particularities of their physical characteristics,older patients undergoing surgery under general anesthesia experience great surgical traumas.Thus,exploring more refined and individualized nursing approaches is an urgent need to mitigate the negative effects of surgery on such patients.AIM To analyze the influence of preoperative comprehensive education on anxiety,depression,pain,and sleep in older patients who underwent surgery under general anesthesia.METHODS In total,163 older adults who underwent surgery under general anesthesia between June 2022 and November 2023 were selected,77 of them received routine nursing care(control group),and 86 received preoperative comprehensive education(research group).Subsequently,comparative analyses were performed from the following perspectives:Surgical indicators(operation time,time to complete regain of consciousness,and temperature immediately after the procedure and upon recovery from anesthesia)before and after nursing care;negative emotions[self-rating anxiety scale(SAS)/self-rating depression scale(SDS)];pain severity[visual analog scale(VAS)];sleep quality[Pittsburgh sleep quality index(PSQI)];incidence of sleep disturbances(difficulties in falling asleep for the first time,falling asleep again after waking up frequently at night,falling asleep again after waking up early,and falling asleep all night);and incidence of adverse events(airway obstruction,catheter detachment,aspiration,and asphyxia).RESULTS The research group had significantly lower operation time and time to complete regain of consciousness than the control group after nursing care and markedly better recovery of postoperative body temperature and body temperature at awakening.In addition,more notable decreases in SAS,SDS,VAS,and PSQI scores were observed in the research group than in the control group.Furthermore,the incidence rate of sleep disturbance(8.14%vs 29.87%)and adverse events(4.65%vs 19.48%)were lower in the research group than in the control group.CONCLUSION Preoperative comprehensive education in older patients who underwent surgery under general anesthesia can improve postoperative indicators,effectively reduce the occurrence of anxiety and depression,alleviate postoperative pain,and improve sleep quality.

Progress of systematic psychological interventions in elderly patients with femoral fractures:A comprehensive review

This review aims to gain a deeper understanding of the psychological state of elderly patients with femoral fractures and provide more theoretical and practical support for clinical treatment and care.Through a literature analysis,we found that elderly patients with femoral fractures face various psychological issues such as anxiety,depression,sleep disorders,and social isolation.The application of systematic nursing interventions in clinical practice,including cognitivebehavioral therapy,mindfulness therapy,family therapy,art therapy,interpersonal therapy,emotion-focused therapy,and relaxation training,has yielded significant results.Systematic psychological interventions can improve the psychological state and quality of life of elderly patients with femoral fractures.Therefore,promoting the application and practice of systematic psychological interventions in the clinical care of elderly patients with fractures will provide more effective psychological services to a wider group of patients with fractures in the future.

The Relationship between Fractures and Tectonic Stress Field in the Extra Low-Permeability Sandstone Reservoir at the South of Western Sichuan Depression

The formation and distribution of fractures are controlled by paleotectonic stress field, and their preservative status and effects on development are dominated by the modern stress field. Since Triassic, it has experienced four tectonic movements and developed four sets of tectonic fractures in the extra low-permeability sandstone reservoir at the south of western Sichuan depression. The strikes of fractures are in the S-N, NE-SW, E-W, and NW-SE directions respectively. At the end of Triassic, under the horizontal compression tectonic stress field, for which the maximum principal stress direction was NW.SE, the fractures were well developed near the S-N faults and at the end of NE-SW faults, because of their stress concentration. At the end of Cretaceous, in the horizontal compression stress fields of the NE-SW direction, the stress was obviously lower near the NE-SW faults, thus, fractures mainly developed near the S-N faults. At the end of Neogene-Early Pleistocene, under the horizontal compression tectonic stress fields of E-W direction, stress concentrated near the NE-SW faults and fractures developed at these places, especially at the end of the NE-SE faults, the cross positions of NE-SW, and S-N faults. Therefore, fractures developed mostly near S-N faults and NE-SW faults. At the cross positions of the above two sets of faults, the degree of development of the fractures was the highest. Under the modern stress field of the NW-SE direction, the NW-SE fractures were mainly the seepage ones with tensional state, the best connectivity, the widest aperture, the highest permeability, and the minimum opening pressure.

Depression and chronic heart failure in the elderly： an intriguing relationship

Chronic heart failure and depressive disorders have a high prevalence and incidence in the elderly. Several studies have shown how depression tends to exacerbate coexisting chronic heart failure and its clinical outcomes and vice versa, especially in the elderly. The negative synergism between chronic heart failure and depression in the elderly may be approached only taking into account the multifaceted pathophysiological characteristics underlying both these conditions, such as behavioural factors, neurohormonal activation, inflammatory mediators, hypercoagulability and vascular damage. Nevertheless, the pathophysiological link between these two conditions is not well established yet. Despite the high prevalence of depression in chronic heart failure elderly patients and its negative prognostic value, it is often unrecognized especially because of shared symptoms. So the screening of mood disorders, using reliable questionnaires, is recommended in elderly patients with chronic heart failure, even if cannot substitute a diagnostic interview by mental health professionals. In this setting, treatment of depression requires a multidisciplinary approach including： psychotherapy, antidepressants, exercise training and electroconvulsive therapy. Pharmacological therapy with selective serotonin reuptake inhibitors, despite conflicting results, improves quality of life but does not guarantee better outcomes. Exercise training is effective in improving quality of life and prognosis but at the same time cardiac rehabilitation services are vastly underutilized.

Artificial tiger bone powder for improving the quality of life in elderly patients with fracture

Objective: To investigate the application of artificial tiger bone powder on fracture healing time, wrist functional recovery and quality of life (QOL) in elderly patients with distal radius fracture. Methods: The study was a randomised controlled trials performed from January 2015 to December 2016 in a hospital. Elderly patients with distal radius fracture were divided into the treatment and the control groups by the random sealed envelope method. All patients were given splint or plaster fixation after manipulative reduction, and functional exercise, the treatment group was also given artificial tiger bone powder orally (trade name: Jintiange capsule), the control group was given an oral placebo in their appearance and usage identical with the treatment group. Prior to treatment and 6, 12 months after treatment, the wrist function was assessed by range of motion, including flexion-extension, radial-ulnar and pronation-supination, and the QOL was assessed by the Mos 36-item Short Form Health Survey. Each patient's fracture healing time was recorded. Results: Before treatment, there were no significant differences in wrist function and QOL between the two groups. At 6 and 12 months after treatment, the wrist function and QOL in the treatment group were better than those in the control group, the differences were statistically significant (P < 0.05). The fracture healing time in the treatment group was shorter than that of the control group, and the difference was statistically significant (P < 0.05). Conclusion: The early usage of artificial tiger bone powder for elderly patients with distal radius fracture can promote the healing of fracture, recovery of wrist joint function, and ultimately improve the QOL for elderly patients.

Total hip arthroplastyvs. osteosynthesis in acute complex acetabular fractures in the elderly:Evaluation of surgical management and outcomes

Objective: To retrospectively evaluate the open reduction internal fixation and total hip arthroplasty directions, results and complications associated with internal fixation in managing these fractures. <br> Methods: In 8 years at 4 centers, 61 patients with associated acetabular fractures (Letournel classification) were treated. The patients were divided into two groups. The total hip arthoplasty (THA) group consisted of 30 patients, while the open reduction internal fixation group had 31 patients. The average age of the patients was 74.7 years. The following parameters were compared: the duration of surgery and hospitalization, the international unit of red blood cell concentrate transfusion, the time for the verticalization of the patient, perioperative complications, Harris hip score, and the short form (12) health survey. The clinical and radiographic follow-up was performed at 1 month, 3 months, 6 months and 12 months and annually thereafter. Patients with post-traumatic osteoarthritis formed the third comparison group.P≤ 0.05 was considered statistically significant according to the analytical Student’s t-test. <br> Results: TheP < 0.05 in favor of theTHAgroup was: surgical time, length of stay, number of the international unit of red blood cell concentrate transfusions, verticalization, quality of life and hip function, a reduction of perioperative complications and reinterventions. <br> Conclusions: Our experience shows that theTHA treatment for acetabular fractures in the elderly is to be preferred.

The power of informal institutions:The impact of clan culture on the depression of the elderly in rural China

Exploration of ways to improve the subjective welfare of residents is an important area of current academic research.Using data from the China Family Panel Studies survey conducted in 2010,this paper investigated the impact of clan culture on the mental health of elderly people in rural China.The results demonstrated that clan culture can significantly decrease the depression score of the rural elderly.Further,there was no gender difference with respect to the impact of clan culture on the depression score of the elderly.At the same time,the positive effects of clan culture on the depression score of the elderly have gradually weakened with economic development.Exploration of the mechanisms involved indicated that in areas with stronger clan culture,older people receive more social support.This study enriches our understanding of the impact of informal institutions on the welfare of rural residents.At the same time,it can also provide a certain decisionmaking reference for the government to formulate relative poverty relief strategies in a new stage of poverty alleviation.

Influence of early postoperative complication on the operative results in elderly intertrochanteric fractured patients

Objective： Early complications were analyzed in those with Evans Ⅲ type of intertrochanteric fracture treated with operation or nonoperative approaches. Methods：59 cases with Evans Ⅲ type of intertrochanteric fracture between June, 1999 to July, 2006 were admitted in our department. 38 patients were complicated with cardiovascular diseases, such as hypertension and arrhythmia. All the cases were operated. Results：58 cases were operated successfully. One died of pulmonary interstitial fibrosis. Grade data of different age brackets indicated that early infective complications had apparent differences between the operation and the control group. Compared with the control group, the operation group had benefits such as fewer complications, especially the infective complications, and incidence of lower extremities venous thrombosis, and the results showed notable differences. Conclusion：In elderly patients with Evans Ⅲ type of intertrochanteric fracture, the incidence of pulmonary infection was the highest. Venous thrombosis in lower extremities was the most serious complication. So it will be helpful to perform the quadriceps femories function exercise. The postoperative effect is also related with the operation approach.

External fixation is more suitable for intra-articular fractures of the distal radius in elderly patients

The purpose of this study was to compare the functional outcomes, psychological impact, and complication rates associated with external fixation and volar or dorsal plating in relation to the functional parameters following treatment of intra-articular fractures of the distal radius （IFDR） in patients older than 65 years. We hypothesized that using volar or dorsal plating would improve functional outcomes, but that it would be associated with more complications and equivalent functional outcomes when compared with the external fixation group. A total of 123 consecutive patients suffering from IFDR were recruited into the study. The patients were measured for clinical, radiological, and psychosocial functioning outcomes and were followed up after I week and 3, 6 and 12 months. After 3 months, the plating group had better pronation （P = 0.001）, supination, （P = 0.047） and extension （P = 0.043） scores. These differences were somewhat attenuated by 6 months and disappeared at I year. The plating group had a greater occurrence of wound infection （P = 0.043）, tendonitis, （P = 0.024） and additional surgery compared with the external fixation group. The only TNO-AZL Adult Quality of Life scores in the plating group that were lower than those in the external fixation group were in the ＂gross motor＂ category （walking upstairs, bending over, walking 500 yards; P = 0.023）. Internal fixation was more advantageous than external fixation in the early rehabilitation period; after I year the outcomes were similar. The plating group showed significantly higher levels of wound infection and tendonitis and had a greater need for additional surgeries.

Therapeutic Effect of Artificial Femoral Head Replacement and Proximal Femoral Nail Antirotation on Elderly Unstable Intertrochanteric Fractures

Objective: To compare the clinical efficacy of artificial femoral head replacement and Proximal femoral nail antirotation (PFNA) in the treatment of unstable femoral intertrochanteric fractures in the elderly. Methods: This study retrospectively analyzed 60 elderly patients with unstable intertrochanteric fractures treated with PFNA and artificial femoral head replacement from 2015.06 to 2018.06, of which 34 were in the PFNA group (Group A) and 26 in the artificial femoral head replacement group (Group B). Statistical analysis of relevant surgical indicators such as surgical time, intraoperative blood loss, postoperative blood transfusion, postoperative time to landing, postoperative infection rate, hospital stay, number of secondary operations, postoperative VAS score, and postoperative Hip function score comparison. Results: All 60 patients were followed up for 1 - 24 months. Compared with the artificial femoral head replacement group, the operation time of PFNA group was shorter, the blood loss during operation was less, and the difference was statistically significant (P 0.05). Conclusion: The hip joint function and pain scores of the artificial femoral head replacement group in the early and follow-up periods are better than those of the PFNA group. The artificial femoral head replacement is more suitable for the treatment of elderly unstable intertrochanteric fractures.

New-onset depression after hip fracture surgery among older patients:Effects on associated clinical outcomes and what can we do?

BACKGROUND Hip fracture in the elderly is a worldwide medical problem.New-onset depression after hip fracture has also received attention because of its increasing incidence and negative impact on recovery.AIM To provide a synthesis of the literature addressing two very important questions arising from postoperative hip fracture depression(PHFD)research:the risk factors and associated clinical outcomes of PHFD,and the optimal options for intervention in PHFD.METHODS We searched the PubMed,Web of Science,EMBASE,and PsycINFO databases for English papers published from 2000 to 2021.RESULTS Our results showed that PHFD may result in poor clinical outcomes,such as poor physical function and more medical support.In addition,the risk factors for PHFD were summarized,which made it possible to assess patients preoperatively.Moreover,our work preliminarily suggested that comprehensive care may be the optimal treatment option for PHFDs,while interdisciplinary intervention can also be clinically useful.CONCLUSION We suggest that clinicians should assess risk factors for PHFDs preoperatively,and future research should further validate current treatment methods in more countries and regions and explore more advanced solutions.

Unpacking the Associations between Traumatic Events and Depression among Chinese Elderly: Two Dimensions of Aging Attitudes as Mediators and Moderators

Traumatic events have been considered significant risk factors for older adults’mental health,but the mediating mechanism and moderating effect of aging attitudes that underlie this relationship have yet been completely investigated.The attitudes of the elderly toward aging can be divided into two closely related but conceptually different dimensions,including positive and negative.Positive aging attitudes refer to optimistic feelings and experiences about aging,whereas negative attitudes toward aging are related to detrimental thoughts and sensa-tions experienced about the increasing age.The purpose of this study is to explore the mediating and moderating roles of these two dimensions of aging attitudes between traumatic events and depression of the elderly in China.Data for this research come from the China Longitudinal Aging Social Survey(CLASS)of 2014.A nationally representative sample consisting of 11,511 Chinese older adults aged 60 and above was obtained through a stra-tified,multi-stage probability sampling method.The results revealed that the association between traumatic events and depression was mediated and moderated by positive and negative aging attitudes,controlling for gen-der,age,spouse,educational level,and ethnicity.Significance,implications,and limitations were discussed.
