Quality of life of patients with hip fracture was better during the COVID-19 period than before, an ancillary study from the HiFIT multicenter study.

Background: The COVID-19 pandemic had a global impact on people life, notably because of lockdown periods. This could particularly affected patients suffering from hip fracture, who could have been more isolated during these periods. We aim at evaluating the impact of the COVID-19 period (including lockdown periods) on quality of life (QOL) in older adult patients 90 days after a surgery for a hip fracture. Subject and methods: Ancillary study of the prospective randomized controlled HiFIT study. We compared the QOL measured at 90 days after a hip fracture surgery using the EuroQOL-5 dimensions 3 levels (EQ-5D), the Perceived Quality of life (PQOL) and the Instrumental Activities of Daily Living (IADL) in patients included in the Hifit study before and during the COVID-19 pandemic. Results: The characteristics of the 161 patients included before and of the 213 included during the COVID period (including 122 (57%) during COVID with containment periods and 91 (43%) during COVID without containment periods) were similar (mean age 84 ± 10 years; 282 (75%) women). The majority (81%) of the patients alive at 90 days had returned to their previous place of residence in both periods. During the COVID period, EQ-5D showed better patient pain/discomfort and anxiety/depression levels. The PQOL happiness was not different, with around 81% of the patient being "happy" or "very happy" during the two periods and the IADL was also similar during the two periods. In the multivariate analysis odd ratios of having poorer outcomes were increased before COVID for pain/discomfort (OR 2.38, 95%CI [1.41-4.15], p = 0.001), anxiety (OR 1.89 [1.12-3.21], p = 0.017) and mobility (1.69 [1.02-2.86], p = 0.044). Conclusion: Patient's quality of life measured using different scales was not altered during the COVID period compared to before COVID, 90 days after a hip fracture. Surprisingly, the Pain/Discomfort and Anxiety dimensions of the EQ-5D questionnaires were even better during the COVID period.Clinical trial registration:https://clinicaltrials.gov/ (NCT02972294).

Influences of Cognitive Function and Depressive Symptoms on Pain Trajectories During the First Year Following Hip Fracture Surgery: A Prospective Cohort Study.

OBJECTIVES: The purposes of this study were to explore trajectories for patterns of postoperative pain intensity during the first year following hip fracture surgery and the relationships between pain trajectory groups, cognitive impairment, and depressive symptoms. DESIGN: A prospective cohort correlational study. SETTING AND PARTICIPANTS: A total of 325 patients aged 60 years or older who had received hip fracture surgery at a 3000-bed medical center in northern Taiwan from September 2012 to March 2020. METHODS: Data were collected before hospital discharge and at 1, 3, 6, and 12 months postdischarge. Pain intensity was measured using a numeric rating scale; cognitive function was measured with the Taiwan version of the Mini-Mental State Examination; and depressive symptoms were measured by the Geriatric Depression Scale-Short Form. Patients with similar postoperative pain trajectories were categorized into groups and compared with group-based trajectory modeling. Cognitive impairment and depressive symptoms associated with each group were identified by logistic regression. RESULTS: Three different pain trajectory groups were identified: drastic decline-minimum pain (47.7%), gentle decline-mild pain (45.5%), and slight decline-moderate pain (6.8%). Patients with cognitive impairment [odds ratio (OR) 11.01, 95% CI 2.99-10.51] and at risk for depression (OR 49.09, 95% CI 10.46-230.30) were more likely to be in the moderate pain group than the minimum pain group. Patients with cognitive impairment (OR 2.07, 95% CI 1.25-3.42) were more likely to be in the mild pain group than the minimum pain group. Patients at risk for depression (OR 9.68, 95% CI 3.16-29.63) were more likely to be in the moderate pain group than the mild pain group. CONCLUSIONS AND IMPLICATIONS: Identifying postoperative pain trajectories can provide insight into the most appropriate pain management for older persons following hip fracture surgery. Attention should focus on assessments for cognitive impairment and risk of depression to prevent persistent postoperative pain. Future studies of older patients with clinically diagnosed cognitive impairment and depression are suggested.

Exploring Factors Associated With Resilience and Physical Activity in Older Men and Women Post-Hip Fracture.

This study aimed to test a model of factors associated with resilience and physical activity post-hip fracture and compare model fit between men and women. We used data from the seventh Baltimore Hip Study that included 339 participants. Model testing indicated that health status (men: ß = .237, p = .002; women: ß = .265, p = <.001), depression (men: ß = -.245, p = .001; women: ß = -.241, p = <.001), and optimism (men: ß = .320, p = <.001; women: ß = .282, p = <.001) were associated with resilience in men and women, but resilience was only associated with physical activity in men (ß = .203, p = .038) and not in women. Social interaction was related to physical activity only among women (ß = .206, p = .044). This study provides support for the relationship between resilience and physical activity at least among men.

Traditional compared to modified method of disinfection before hip fracture surgery - Experiences of nursing personnel.

BACKGROUND: National guidelines in Sweden recommend preoperative full-body disinfection (FBD) with 4% chlorhexidine to prevent surgical-site infection (SSI) after hip fracture surgery, a method causing patients' severe pain. Although, due to little evidence in research, orthopedic clinics in Sweden are wavering in favor of simpler methods such as local disinfection (LD) of the surgical site. PURPOSE: The aim of this study was to describe the experiences of nursing personnel regarding the performance of preoperative LD on patients prior to hip fracture surgery after having switched from FBD. METHODS: This study has a qualitative design where data were collected via focus-group discussions (FGDs) including in total 12 participants and analysed using content analysis. RESULTS: Six categories were identified describing the aim: sparing the patients' physical harm, sparing the patients' psychological distress, involving the patients in the procedure, improving the working environment for personnel, preventing unethical situations and a more adequate utilization of resources. CONCLUSIONS: All participants considered LD of the surgical site as a favorable method to FBD, witnessing of an increased wellbeing in patients and the method facilitating a better involvement of patients in the procedure, findings that are supported by other studies promoting person-centered care.

Cerebrospinal fluid quinolinic acid is strongly associated with delirium and mortality in hip-fracture patients.

BACKGROUNDThe kynurenine pathway (KP) has been identified as a potential mediator linking acute illness to cognitive dysfunction by generating neuroactive metabolites in response to inflammation. Delirium (acute confusion) is a common complication of acute illness and is associated with increased risk of dementia and mortality. However, the molecular mechanisms underlying delirium, particularly in relation to the KP, remain elusive.METHODSWe undertook a multicenter observational study with 586 hospitalized patients (248 with delirium) and investigated associations between delirium and KP metabolites measured in cerebrospinal fluid (CSF) and serum by targeted metabolomics. We also explored associations between KP metabolites and markers of neuronal damage and 1-year mortality.RESULTSIn delirium, we found concentrations of the neurotoxic metabolite quinolinic acid in CSF (CSF-QA) (OR 2.26 [1.78, 2.87], P < 0.001) to be increased and also found increases in several other KP metabolites in serum and CSF. In addition, CSF-QA was associated with the neuronal damage marker neurofilament light chain (NfL) (ß 0.43, P < 0.001) and was a strong predictor of 1-year mortality (HR 4.35 [2.93, 6.45] for CSF-QA ≥ 100 nmol/L, P < 0.001). The associations between CSF-QA and delirium, neuronal damage, and mortality remained highly significant following adjustment for confounders and multiple comparisons.CONCLUSIONOur data identified how systemic inflammation, neurotoxicity, and delirium are strongly linked via the KP and should inform future delirium prevention and treatment clinical trials that target enzymes of the KP.FUNDINGNorwegian Health Association and South-Eastern Norway Regional Health Authorities.

Indicators of Improvement in Performing Activities of Daily Living Among Older Patients Undergoing Rehabilitation Following Hip Fractures.

This study aimed to evaluate the relationship between improvement in activities of daily living (ADL) and cognitive status during rehabilitation and assess factors associated with ADL improvement among older patients undergoing rehabilitation after hip fractures. This retrospective cohort study comprised 306 patients aged ≥80 years who underwent hip fracture rehabilitation. The functional independence measure gain during rehabilitation was significantly lower in the group with abnormal cognition than in the group with normal cognition. Mini-Mental State Examination, Charlson Comorbidity Index, daily duration of rehabilitation, and length of hospitalization for rehabilitation were independent factors associated with functional independence measure gain during rehabilitation in the multivariate regression analysis. Although older patients with cognitive impairment had lower ADL improvements during hip fracture rehabilitation, such patients may be able to improve their ADL by undergoing intensive and long rehabilitation programs. They should not refrain from such rehabilitation programs due to older age, fracture, and cognitive impairment.

A quality improvement project addressing the underreporting of delirium in hip fracture patients.

INTRODUCTION: After discovering a low incidence of delirium for hip fracture patients at our institution, we evaluated if this was due to underreporting and, if so, where process errors occurred. METHODS: Hip fracture patients aged ≥60 with a diagnosis of delirium were identified. Chart-Based Delirium Identification Instrument (CHART-DEL) identified missed diagnoses of delirium. Process maps were created based off staff interviews and observations. RESULTS: The incidence of delirium was 15.3% (N = 176). Within a random sample (n = 98), 15 patients (15.5%) were diagnosed, while 20 (24.7%) went undiagnosed despite evidence of delirium. Including missed diagnoses, delirium prevalence was higher in the sample compared to all patients (35.7% vs 15.3%, p < 0.001). Most missed diagnoses were due to failure in identifying delirium (60%) or failure in documenting/coding diagnosis (20%). The prevalence of baseline cognitive impairment was higher in undiagnosed delirium patients versus correctly diagnosed patients (80% vs 20%, p = 0.001). CONCLUSIONS: Our institution significantly underreports delirium among hip fracture patients mainly due to; (1) failure to identify delirium by the clinical staff, and (2) failure to document/code diagnosis despite correct identification. Baseline cognitive impairment can render delirium diagnosis challenging. These serve as targets for quality improvement and hip fracture care enhancement.

The journey of recovery after hip-facture surgery: older people's experiences of recovery through rehabilitation services involving physical activity.

Purpose: This study sought to explore and describe the experiences of recovery among community-living older people undergoing rehabilitation involving physical activity following hip-fracture surgery.Methods: We conducted in-depth interviews with 5 men and 16 women (age range: 67 - 84 years). The data were analysed by means of systematic text condensation.Results: The analysis revealed the following four interrelated themes: (1) what participants bring to the recovery situation matters; (2) support through individually tailored rehabilitation services, involving physical activity, - is key to recovery following hip fracture surgery; (3) needing professional help on the journey from helplessness and vulnerability to being more confident and active; and (4) making progress and regaining function represent the essence of recovery.Conclusions: All four identified themes relate to how physical activity, as an aspect of rehabilitation services, contributes to the recovery process for patients who have experienced a hip fracture. Differences were reported with regard to the services used, and all the participants were at the mercy of what their municipalities chose to offer in terms of rehabilitation services.IMPLICATIONS FOR REHABILITATIONMunicipal healthcare services should address patients' individual needs when planning, organising and implementing rehabilitation programmes involving physical activity.Healthcare professionals need to recognise older patients' experiences of reduced physical, psychological and social functioning following hip-fracture surgery and then take those experiences into account when tailoring rehabilitation programmes.Healthcare professionals providing physical rehabilitation programmes to people who have undergone hip-fracture surgery should take into account their patients' situation and lifestyle prior to experiencing a hip fracture.Municipal healthcare services should consider using recovery as a conceptual framework in relation to rehabilitation services involving physical activity.

Differential misclassification of cognitive impairment by sex among hip fracture patients.

BACKGROUND: Males have worse outcomes after hip fracture than female counterparts. Cognitive impairment (CI) also increases the risk of poor recovery from hip fracture; however, CI is under-recognized. Patient sex may contribute to this under-recognition through differential misclassification. The objective of this study was to measure under-recognition and differential misclassification of CI by patient sex. METHODS: A cross-sectional analysis of baseline data from an observational cohort study of community-dwelling hip fracture patients aged 65 and older (n = 339; females = 171, males = 168) recruited from eight hospitals in the greater Baltimore, MD area within 15 days of hospitalization for surgical repair with cognitive testing within 22 days of admission. Indication of Alzheimer's disease or related dementias and/or delirium as a postoperative complication in the medical record was considered evidence of documented CI. Observed CI was measured with the Modified Mini-Mental State Examination (3MS, ≤78). Source of cognitive impairment identification (SCI) was defined as: "3MS Only," "Hospital Record Only," "Both," "No CI" was compared between males and females using logistic regression. RESULTS: Males had more comorbidities and worse physical status upon admission, but otherwise had similar hospital experiences. SCI distribution was 12.7% "3MS Only" (n = 42), 11.5% "Hospital Record Only" (n = 38), 9.4% "Both" (n = 31), and "No CI" (n = 219). Males were more likely to be identified with CI using the "3MS Only" and "Both," and females were more likely to have no indication of CI. CONCLUSION: There were sex differences in the documentation of CI versus observed impairment. Males had more CI using direct testing. This may be contributing to sex differences in recovery outcomes after hip fracture. Results support the implementation of cognitive testing in hip fracture patients to reduce the impact of differential misclassification by patient sex.

Increased Serum Neuropeptide Galanin Level Is a Predictor of Cognitive Dysfunction in Patients with Hip Fracture.

BACKGROUND: Hip fracture is a common occurrence in elderly populations and is frequently followed by various levels of cognitive dysfunction, leading to adverse functional outcomes. Risk stratification of hip fracture patients to identify high-risk subsets can enable improved strategies to mitigate cognitive complications. The neuropeptide galanin has multiple neurological functions, and altered levels are documented in dementia-type and depression disorders. The present study investigated the association of serum neuropeptide galanin levels in hip fracture patients with the occurrence of cognitive dysfunction during the first week of admission. METHODS: 276 hip fracture patients without preexisting delirium, cognitive impairment, or severe mental disorders were included in a cross-sectional study. Serum galanin levels were assessed by ELISA on the second day of admission. Routine clinical and laboratory variables were documented. MoCA was performed within 1 week, and those with a score < 26 were categorized with "cognitive decline." Inferential statistics including multiple linear regression analysis were applied to determine the association of serum galanin level and cognitive status. RESULTS: 141 patients were categorized with "cognitive decline," and 135 patients were categorized as "cognitively normal." Serum galanin was highly significantly increased in the "cognitive decline" group (34.2 ± 4.8, pg/ml) compared to the "cognitively normal" group (28.9 ± 3.7, pg/ml) and showed significant negative correlation with MoCA scores (r = -0.229, p = 0.016). Regression analysis showed serum galanin as the sole significant independent predictor of lower MoCA scores (ß = 0.231, p = 0.035) while age, gender, blood pressure, cholesterol, and blood glucose levels had no significant association. CONCLUSION: Higher serum galanin predicted the development of cognitive dysfunction and worse MoCA scores in a cohort of hip fracture patients without preexisting cognitive impairment or delirium at admission, thus warranting large-scale studies investigating galanin as a candidate biomarker to identify hip fracture patients at risk of cognitive decline.

Is There an Association between Norton Scale and Cognitive Impairment in Hip Fractured Elderly Patients?

INTRODUCTION: Geriatric assessment as an integrative part of assessment is a composite of a large number of scales. Sometimes it is difficult to transfer all of them. The Norton Scale Score (NSS) assesses the degree of risk to develop bedsores. In previous studies, a correlation between Norton Scale and function was found. A correlation between Norton Scale and cognitive assessments was not evaluated yet. The aim of this study was to determine if there is an association between Norton Scale Score and cognitive impairment. This association can further facilitate geriatric assessment in frail older patients, especially in older patients with communicative difficulties. METHODS: We have performed an observational cohort study which included hip fractured older patients consecutively admitted to the rehabilitation ward of the Shmuel Harofe Geriatric Medical Center. The collected data included demographic data and data on chronic illnesses. Results of cognitive status assessment (Mini-Mental State Examination - MMSE) and Norton Scale assessment were received from the computerized patients' charts. We evaluated the association between these 2 scales. RESULTS: The study included 224 consecutive hip fracture patients with a mean age of 81.78 ± 7.19 years. Norton scores at admission, age, education, and previous stroke emerged as the only statistically significant parameters differing between those with cognitive decline and those without it. After adjusting for confounding variables, lower Norton scores at admission (OR 1.303, CI: 1.097-1.548, p = 0.003) were associated with an increased risk finding for cognitive impairment. CONCLUSION: Our findings suggest that there is an association between Norton Scale Scores and cognitive impairment. Norton score parameters, under certain circumstances, such as speech and other communication difficulties, can be used as a proxy measure for MMSE to indicate cognitive impairment. These findings can be even more helpful in the present time of "COVID-19," when we have to evaluate older patients with facial masks and other defensive suits.

A Beneficial Bipolar Hemiarthroplasty on a Centenarian in One Developing Country.

Geriatric hip fractures are common; however, surgery on a 100-year-old patient is rare in Indonesia.  We report arthroplasty in 100-year-old woman with right hip fracture and right Colles fracture; which benefits her a three year of active and qualified life. Despite her age, the patient was quite independent, active, and mobile beforehand. Hence a meticulous preoperative planning and post-operative rehabilitation were structured by a comprehensive medic and non-medic geriatric team. Cementless bipolar hemiarthroplasty was perfectly sufficient for the hip fracture under regional anesthesia while the Colles fracture was managed with a close reduction and plastering. Rehabilitation was started on Day-2 and continued weeks after discharge. The patient is still alive and well 3 years after the surgery. Surgery is beneficial for the 100-year-old patient; it is in the best interests of the patient's mobility and quality of life. Age alone should not limit a surgical decision as long as all comorbidities are controlled by a comprehensive medic and non-medic geriatric team.

Feasibility of a multicomponent cognitive behavioral intervention for fear of falling after hip fracture: process evaluation of the FIT-HIP intervention.

BACKGROUND: This study describes the process evaluation of an intervention developed to reduce fear of falling (FoF) after hip fracture, within an inpatient geriatric rehabilitation setting. This 'FIT-HIP intervention' is a multicomponent cognitive behavioral intervention, conducted by physiotherapists and embedded in usual care in geriatric rehabilitation in the Netherlands. A previous study (cluster randomized controlled trial) showed no beneficial effects of this intervention when compared to usual care. The aim of this study was to gain insight into factors related to the intervention process that may have influenced the effectiveness of the intervention. METHODS: This process evaluation was conducted using an observational prospective study design. Based on quantitative and qualitative data derived from session logs, evaluation questionnaires and interviews, we addressed: 1] recruitment and reach; 2] performance according to protocol; 3] patients' adherence; and 4] opinions of patients and facilitators on the intervention. Participants in this study were: a) patients from 6 geriatric rehabilitation units, who were invited to participate in the intervention (39 adults aged ≥65 years with hip fracture and FoF) and; b) intervention facilitators (14 physiotherapists and 8 psychologists who provide coaching to the physiotherapists). RESULTS: Thirty-six patients completed the intervention during inpatient geriatric rehabilitation. Apart from cognitive restructuring and telephonic booster (which was not provided to all patients), the intervention was performed to a fair degree in accordance with protocol. Patients' adherence to the intervention was very good, and patients rated the intervention positively (average 8.1 on a scale 0-10). Although most facilitators considered the intervention feasible, a limited level of FoF (possibly related to timing of intervention), and physiotherapists' limited experience with cognitive restructuring were identified as important barriers to performing the intervention according to protocol. CONCLUSIONS: The FIT-HIP intervention was only partly feasible, which may explain the lack of effectiveness in reducing FoF. To improve the intervention's feasibility, we recommend selecting patients with maladaptive FoF (i.e. leading to activity restriction), being more flexible in the timing of the intervention, and providing more support to the physiotherapists in conducting cognitive restructuring.

A multi-center trial of exercise and testosterone therapy in women after hip fracture: Design, methods and impact of the COVID-19 pandemic.

BACKGROUND: Up to 75% of hip fracture patients never recover to their pre-fracture functional status. Supervised exercise that includes strength training can improve functional recovery after hip fracture. The role of testosterone replacement for augmenting the effects of exercise in older women after hip fracture is unknown. METHODS: The Starting Testosterone and Exercise after Hip Injury (STEP-HI) Study is a 6-month Phase 3 multicenter randomized placebo-controlled trial designed to compare supervised exercise (EX) plus 1% testosterone topical gel, with EX plus placebo gel, and with enhanced usual care (EUC). Female hip fracture patients age ≥ 65 years are being recruited from clinical centers across the United States. Participants are community dwelling and enrolled within 24 weeks after surgical repair of the fracture. The EX intervention is a center-based program of progressive resistance training. The EUC group receives a home exercise program and health education. Participants receive dietary counseling, calcium and vitamin D. The primary outcome is the Six Minute Walk Distance. Secondary outcomes include physical performance measures, self-reported function and quality of life, and dual energy x-ray absorptiometry measures of body composition and bone mineral density. RESULTS: Enrollment, interventions, and follow-up are ongoing. We describe the impact of the coronavirus disease 2019 pandemic on the trial, including modifications made to allow continuation of the interventions and outcome data collection using remote video and audio technology. CONCLUSIONS: Results from the STEP-HI study are expected to have important clinical and public health implications for management of the growing population of hip fracture patients.

Spiritual coping strategies and quality of life in older adults who have sustained a hip fracture: A cross-sectional survey.

AIMS: To investigate the relationship between spiritual coping strategies and quality of life in persons with a hip fracture. DESIGN: A correlational, cross-sectional survey design. METHODS: The total population of Maltese-speaking adults over 65 years (N = 299), with a hip fracture receiving treatment in a public hospital in Malta in 2015, were invited. The WHOQOL-BREF questionnaire and the Spiritual Coping Strategies Scale were used. RESULTS: A response rate of 51% (n = 147) was achieved. The poorest quality of life was for the physical and psychological domains. Spiritual coping strategies were associated with better quality of life with the exception of physical quality of life. Non-religious coping strategies were the stronger predictor of quality of life compared with religious coping strategies. The former predicted physical, psychological, environmental, social and overall quality of life. CONCLUSION: Hip fractures have serious implications on quality of life which could be improved by promoting non-religious spiritual coping strategies.

Good clinical outcome for the majority of younger patients with hip fractures: a Swedish nationwide study on 905 patients younger than 50 years of age.

Background and purpose - Studies regarding hip fractures in young patients are rare since the patient population is small. We assessed clinical outcomes 4 months after hip fracture in patients < 50 years of age and whether there were differences between sexes and different age groups.Patients and methods - We included adult patients < 50 years with a hip fracture between January 1, 2014 and December 31, 2018. Baseline data were extracted from the Swedish Registry for Hip Fracture Patients and Treatment (RIKSHÖFT) and mortality data was obtained from Statistics Sweden. The outcome variables were change of walking ability, pain in fractured hip, use of analgesics, living conditions, and mortality rate at 4 months.Results - Of the 905 patients included, 72% were men and femoral neck fractures were most common (58%). 4 months after surgery, 23% used a walking aid and 7% reported severe pain. Women reported slightly more pain and higher usage of analgesics. Patients aged 40-49 reported higher usage of analgesics than patients aged 15-39, although the latter group reported more pain. Nearly all of those who lived independently before fracture did so at 4 months. The mortality rate was < 1%.Interpretation - Most patients did not use any walking aid and few had severe pain at 4 months. Furthermore, a hip fracture is not a life-threatening event in a patient < 50 years. The living conditions did not change for those who lived independently before the fracture.

Impact of a Postoperative Intervention Educational Program on the Quality of Life of Patients with Hip Fracture: A Randomized, Open-Label Controlled Trial.

The objective of this study was to determine the impact of a postoperative educational intervention program on the health-related quality of life (HRQoL) of patients with hip fracture using a controlled clinical trial in a randomized, multicenter study. In total, 102 patients (45.5%) from trauma units at the two University Hospitals of the province of Cáceres received the educational program, whereas 122 (54.5%) did not. Patients were consecutively included in either an intervention or a control group. Patients from the intervention group received an educational program during admission and the postoperative period. Patients from the control group did not receive any educational program. These patients were managed according to routine protocols. The patients were predominantly female (76.3%), aged 84.6 years (SD 6.1). All dimensions in both groups at 12 months showed a significant decrease with respect to baseline, except for bodily pain in both groups (p = 0.447; p = 0.827) and social functioning in the intervention group (p = 0.268). Patients receiving the educational program showed higher levels in the dimensions of the Mental Component Summary (MCS-12) (p = 0.043), vitality (p = 0.010), and social functioning (p < 0.001), as well as in the dimensions of the SF-12 health survey questionnaire of HRQoL 12 months after surgery. In conclusion, our study of the intervention group showed that there were significant improvements in MCS-12, vitality, and social function dimensions compared to the control group.

Factors Affecting Persistent Postoperative Pain in Patients with Hip Fractures.

Osteoporotic fractures are common among older people, and hip fractures (HF) can be devastating. Surgery is indicated for most cases of HF, and chronic persistent postoperative pain is likely to occur. This study investigated the multifaceted factors related to persistent pain occurring during the acute phase and subacute phase of recovery after HF surgery. We conducted a prospective 8-week study of older HF patients after surgery. We evaluated pain intensity, depression symptoms, the fear of falling, pain catastrophizing, cognition and attention, the ability to perform activities of daily living, and the physical performance at 2 weeks (acute phase) and at 4 weeks (subacute phase) after surgery. Patients were divided into the light group (Verbal Rating Scale (VRS) score ≤1) and severe group (VRS score ≥2) according to pain intensity at 8 weeks (recovery phase) after surgery. Factors affecting persistent postoperative pain during recovery were examined using logistic regression analysis. Seventy-two patients were analyzed: 50 in the light group and 22 in the severe group. In the severe group, pain with movement and Pain Catastrophizing Scale scores were higher than those of the light group at 2 weeks and at 4 weeks after surgery. The regression analysis showed that pain with movement at 2 weeks and at 4 weeks after surgery and pain catastrophizing at 4 weeks after surgery were related to persistent postoperative pain. HF patients may have persistent pain if they continue to experience pain and catastrophize their pain during the acute phase and subacute phase after surgery.

Fatty Acid-Binding Protein 3 in Cerebrospinal Fluid of Hip Fracture Patients with Delirium.

BACKGROUND: Delirium is associated with dementia and thus biomarkers reflecting neurodegeneration are of interest. Fatty acid-binding protein 3 (FABP3) is a cytoplasmic neuronal protein that has been isolated from the brain. It is released following brain injury and concentrations in cerebrospinal fluid (CSF) are also higher in neurodegenerative disorders such as Alzheimer's disease (AD). OBJECTIVE: To examine the relationship between CSF FABP3 concentration and delirium in hip fracture patients compared to a group of cognitively normal controls. METHODS: CFS FABP3 concentration was measured in 128 hip fracture patients with (n = 71) and without (n = 57) delirium, and in cognitively unimpaired adults ≥64 years (n = 124) undergoing elective surgery. RESULTS: CSF FABP3 (pg/ml) concentration (median (IQR)) was higher in hip-fracture patients compared to cognitively normal controls (5.7 (4.2-7.7) versus 4.5 (3.4-6.1), p < 0.001). There was a significant weak correlation between age and CSF FABP3 (ρ= 0.3, p < 0.001). After adjustment for age, the association between CSF FABP3 and hip-fracture was no longer statistically significant (ß= 0.05, p = 0.5). There were no significant differences in CSF FABP3 concentration between hip fracture patients with (5.4 (4.1-8.2)) and without (5.8 (4.2-7.2)) delirium. CSF FABP3 concentration correlated positively with CSF AD biomarkers p-tau (ρ= 0.7, p < 0.01) and t-tau (ρ= 0.7, p < 0.01). CONCLUSION: CSF FABP3 concentrations were higher in hip fracture patients compared with cognitively normal older adults, indicating ongoing age-related neurodegeneration in these patients. There were no differences of CSF FABP3 concentrations across delirium groups, suggesting that neuronal damage or degeneration reflected by FABP3 may not be directly linked to delirium pathophysiology.
