Preoperative Drug Monitoring in Management of Patients with Hip Fracture on Treatment with Direct Oral Anticoagulants.

Purpose: Aim of the present study was to evaluate whether monitoring direct oral anticoagulant (DOAC) levels may improve management of anticoagulated patients who need surgery for hip fracture. Patients and Methods: A total of 147 out of 2231 (7.7%) patients with hip fracture admitted to a tertiary teaching hospital were on DOACs (group A), whereas 206 patients matched for age, sex, and type of fracture not on anticoagulant or P2Y12 platelet inhibitors were considered as control group (group B). Patients on DOACs were divided into two subgroups: A1 in which intervention was scheduled in relation to the last drug intake according to current guidelines, and A2 included patients in whom time of surgery (TTS) was defined according to DOAC levels. Neuraxial anesthesia was considered with DOAC levels <30 ng/mL, general anesthesia for levels in the range 30-50 ng/mL. Results and conclusions: TTS was significantly lower in controls than in DOAC patients: surgery within 48 hours was performed in 80.6% of group B versus 51% in group A (p<0.0001). In A2, 41 patients underwent surgery within 48 hours (56%) in comparison to 32 A1 patients (45.1%; p=0.03). TTS and length of hospitalization were on average 1 day lower in patients with assay of DOAC levels. Finally, 35/39 (89%) patients with DOAC levels <50 ng/mL had surgery within 48 hours (26 under neuraxial anesthesia, without any neurological complication, and 13 in general anesthesia). Conclusion: DOAC assay in patients with hip fracture may be useful for correct definition of time to surgery, particularly in patients who are candidates for neuraxial anesthesia. Two-thirds of patients with DOAC levels <50 ng/mL at 48 hours from last drug intake underwent uneventful neuraxial anesthesia, saving at least 24 hours in comparison to guidelines.

Neuropsychiatric disorder as early clinical presentation of marantic endocarditis in patient with newly diagnosed poorly differentiated esophago-gastric junction adenocarcinoma: A case report.

Neuropsychiatric symptoms, depression, and progressive mental confusion should not be overlooked as onset symptoms of multiple cerebral ischemic lesions due to cardiac embolization. Comprehensive clinical evaluation due to progressive anemia led to the diagnosis of poorly differentiated adenocarcinoma of the esophagogastric junction as cause of embolizing nonbacterial mitral endocarditis.

Postoperative Myocardial Infarction after Non-Cardiac Surgery: An Update.

Every year, not less than 300 million non-cardiac surgery interventions are performed in the world. Perioperative mortality after non-cardiac surgery is estimated at 2% in patients over 45 years of age. Cardiovascular events account for half of these deaths, and most are due to perioperative myocardial infarction (MINS). The diagnosis of postoperative myocardial infarction, before the introduction of cardiac biomarkers, was based on symptoms and electrocardiographic changes and its incidence was largely underestimated. The incidence of MINS when a standard troponin assay is used ranges between 8 and 19% but increases to 20-30% with high-sensitivity troponin assays. Higher troponin values suggesting myocardial injury, both with or without a definite diagnosis of myocardial infarction, are associated with an increase in 30-day and 1-year mortality. Diagnostic and therapeutic strategies are reported.

SSRIs in the course of COVID-19 pneumonia: Evidence of effectiveness of antidepressants on acute inflammation. A retrospective study.

INTRODUCTION: Relationships between inflammation and mood have been observed in terms of pro-inflammatory effects induced by depressive conditions and, in parallel, by an antidepressant-induced favorable effect on the recovery of inflammatory states. Selective serotonin reuptake inhibitor (SSRI) drugs were hypothesized to improve the prognosis of COVID-19 pneumonia, a typical acute inflammation, in terms of decreased mortality rate and pro-inflammatory cytokine serum levels. METHODS: The medical records of COVID-19 pneumonia inpatients at Careggi University Hospital (Florence) were analyzed for prognosis and Interleukin 6 (IL-6) after admission for over a period of 22 months. Medical records of patients treated at admission and not discontinued until discharge with an SSRI or with vortioxetine were identified. Two groups, one treated with antidepressants, the other not treated, were evaluated according to the mentioned parameters. Multiple linear regression and logistic regression were performed. RESULTS: The entire sample composed of 1236 records (recovered patients 77.1%, deceased patients 22.9%). The treated group (n = 107) had a better prognosis than the untreated group in spite of age and comorbidity both being greater than in the untreated group. Correspondingly, IL-6 levels in the treated group were significantly lower (p < 0.01) than the levels in the untreated group, in every comparison. CONCLUSIONS: Outcomes of this study support the hypothesis of the favorable influence of some antidepressants on the prognosis of COVID-19, possibly mediated by IL-6 modulation. Reduction in acute inflammation induced by the action of antidepressants was confirmed.

Survival and Results after Resection and Reconstruction with Megaprosthesis at the Hip in Octogenarians.

Few data are available about results after procedures of resection and megaprosthesis at the hip in very elderly patients. The aim of our study was to ascertain survival and complications in patients aged 80 or older undergoing these major orthopedic procedures. A consecutive series of 27 procedures in 26 patients aged 80-93 years was evaluated. In total, 15 procedures were performed due to oncological diseases, 6 were performed following joint arthroplasty failures or periprosthetic fractures, and 6 were performed after trauma or trauma sequelae. Survival of the patients ranged from 0 to 122 months. Overall survival was 56% at 3 years, 24% at 5 years, and 16% at 8 years. An early postoperative death during the first 3 months occurred in five patients (18.5%). The only preoperative parameter negatively affecting survival was preoperative hemoglobin lower than 11 g/dL. Local complications were similar to reported rates in all-age patients' series. In our experience, resection and megaprosthetic reconstruction can also be a valid choice in very elderly patients, with 56% of patients living more than two years from surgery and 24% more than five. Nevertheless, early postoperative deaths are frequent. A multidisciplinary evaluation of frailty of the patient must be accomplished, and patients and relatives must be informed about the risks of the procedure.

Management and 1-Year Outcome in Elderly Patients with Hip Fracture Surgery Receiving Anticoagulation (Warfarin or DOAc) or P2Y12 Antiplatelet Agents.

(1) Background: Little prospective data exist regarding the perioperative management and long-term prognosis of elderly patients receiving treatment with antithrombotic drugs and undergoing urgent surgery for a hip fracture. (2) Methods: The study included patients who required hip surgery and were receiving warfarin, DOAc or P2Y12 antiplatelet agents at the moment of trauma. Ongoing antithrombotic treatment was managed according to existing recommendations. The endpoints of the study were the time to surgery, perioperative bleeding, the need for transfusion and, finally, mortality, major cardiovascular events and re-hospitalization at 6 and 12 months. (3) Results: The study included a total of 138 patients. The mean age was 86 years; 75.4% were female. Eighty-two received DOAc, thirty-six received warfarin and twenty received P2Y12 inhibitors. The controls were 283 age- and sex-matched patients who did not receive antithrombotic treatment. A total of 38% of patients receiving warfarin underwent surgery <48 h, 52% receiving DOAc, 55% receiving P2Y12 inhibitors and, finally, 82% in the control group. Perioperative bleeding and the need for transfusion were not different between the four groups. Mortality at 6 months was higher in patients receiving warfarin and P2Y12 inhibitors (30% and 25%) in comparison to DOAc and the control group (11.6% and 10% p < 0.0001). Similarly, the other endpoints were more frequent in patients receiving warfarin and P2Y12 inhibitors. The trend was maintained for 12 months. No significant differences in mortality were found between early (<48 h) and late (>48 h) surgery independent of the type of treatment. (4) Conclusions: Our study confirmed that anticoagulants delay surgery in patients with hip fractures; however, intervention > 48 h is not associated with a poorer prognosis. This finding is relevant as it underlines that, in patients at high risk of postoperative cardiovascular complications, the careful management of anticoagulation before surgery may compensate for the delay of surgery with a very low in-hospital mortality rate (<1%). One-year survival was significantly lower in patients receiving warfarin, probably related to their worse risk profile at the moment of trauma survival.

Preoperative echocardiography in patients with hip fracture: a prospective cohort study.

Introduction: Although clinical guidelines suggest echocardiography before surgery in patients with hip fracture, no prospective studies exist in the literature. The aim of the present investigation was to assess whether preoperative echocardiography affects time to surgery, length of hospital stay (LOS), and in hospital mortality in high-risk patients who need surgery for a hip fracture. Material and methods: In the study entered 255 consecutive patients with hip fracture referred to a multidisciplinary hip fracture unit. Seven hundred seventeen patients referred before the implementation of routine echocardiographic examination were considered as control group. Echocardiography was performed in patients with systolic murmurs, unstable clinical conditions, recent decompensation of heart failure or hospital admission for coronary disease. Time to surgery, LOS, and in hospital mortality in patients who underwent preoperative echocardiography (high-risk group) were compared with patients who did not undergo echo (low-risk group) and with the control group. Results: 122/255 patients underwent echocardiography. The two groups did not differ for age, sex, type or fracture, and notably time to surgery and LOS. Coronary heart disease, atrial fibrillation, and two or more comorbidities were more frequent in the echo group. Overall clinical characteristics were not different from group of patients referred before the implementation of the echocardiographic protocol but in these last patients time to surgery and LOS were significantly longer. As well in hospital mortality was not significantly different in the two groups (1.9 in echo vs. 1.7% in nonecho) but lower than in the control group (4.1% ). Conclusions: An echocardiographic guide may be useful in a high-risk group with a hip fracture to choose the proper anesthetic setting, referral for intensive care observation after surgery and, optimal medical treatment, including fluid management without delay in time to surgery.

Effects of Atrial Fibrillation Radiofrequency Ablation in Patients Aged > 75 Years Undergoing Mitral Valve Surgery.

BACKGROUND: Few data exist about the efficacy of radiofrequency (RF) maze procedures in elderly patients with atrial fibrillation (AF) undergoing surgery for mitral valve disease. The aim of the present investigation was to evaluate the effects of AF ablation associated with mitral valve surgery on the recovery and long-term maintenance of sinus rhythm in elderly patients aged > 75 years. Moreover, we evaluated the effects on survival. METHODS AND RESULTS: This study included 96 consecutive patients with AF (42 men and 56 women) aged > 75 years (mean age 78 ± 3) who underwent RF ablation associated with mitral valve surgery (group I). This group was compared to 209 younger patients (mean age 65 ± 8 years) treated in the same period (group II). Baseline clinical and echocardiographic characteristics were similar in the two groups. Four patients died during hospitalization, one aged > 75 years. In surviving patients at the end of the follow-up period, sinus rhythm was present respectively in 64% of the elderly and 74% of younger patients (p = 0.778). The rate of persistence of sinus rhythm without AF recurrences (38% vs. 41%, p = 0.705) was similar in the two groups. After surgery, sinus rhythm was frequently never regained in aged patients (27% vs. 20%, p = 0.231). Elderly patients more frequently needed permanent pacing and had more hospitalizations and a higher number of non-AF atrial tachyarrhythmias. At eight-year follow-up, survival was lower in older patients (48% aged > 75 vs. 79% aged < 75 years). CONCLUSION: Elderly patients had a similar long-term rate of stable sinus rhythm maintenance in comparison to younger patients after AF radiofrequency ablation associated with mitral valve surgery. However, they needed more frequent permanent pacing and had higher rates of hospitalizations and post-procedural atrial tachyarrhythmias. The effects of survival are difficult to evaluate due to the different life expectancies of the two groups.

Hip Fracture Surgery in Severe Aortic Stenosis: A Study of Factors Affecting Mortality.

Background: In elderly patients with hip fracture, the prevalence of severe aortic stenosis (valve area <1 cm2) is close to 5%. Few studies have evaluated the prognostic role of aortic stenosis in hip fracture surgery and none has considered the effects of the postoperative setting (intensive care unit vs general ward) on clinical outcome. Purpose: The aim of the present study was to evaluate the factors affecting mortality in patients with severe aortic stenosis undergoing surgery for hip fracture. We also evaluated whether postoperative monitoring in the intensive care unit may affect the prognosis in comparison to return to the general ward after surgery. Patients and Methods: All 2274 patients referred for hip fracture to our tertiary teaching hospital between January 1 2015 and December 31 2019 were screened for the presence of severe aortic stenosis, defined by an aortic valve area <1.0 cm2. Results: The study included 66 patients (27 males, 39 females) with a mean±SD age of 85±7 years. The average time between trauma and surgery was 2.6±3 days. The mean aortic valve area was 0.74±0.15 cm2. Seven patients died during hospitalization (10.4%). Diabetes, having two or more comorbidities, a low degree of autonomy, heart failure, history of coronary artery disease, atrial fibrillation, postoperative delirium and pulmonary hypertension were associated with poorer outcome. In logistic multivariate analysis, the number of diseases and values of pulmonary artery pressure were the only independent factors related to mortality. In hospital mortality (12 and 9%, respectively) and complication rates were not statistically different between patients referred to the intensive care unit for postoperative monitoring and patients returned to the general ward after surgery. Conclusion: In patients undergoing hip fracture surgery, severe aortic stenosis is associated with high hospital mortality, and two or more comorbidities and pulmonary hypertension are associated with a worse prognosis. The postoperative setting (intensive care unit or general ward) does not affect outcome.

Independent, Differential Effects of Delirium on Disability and Mortality Risk After Hip Fracture.

OBJECTIVES: To assess the independent effect of delirium on mortality and disability after 1 year of follow-up, in consecutive older patients with hip fracture hospitalized for surgical repair. DESIGN: This is a prospective observational study. SETTING AND PARTICIPANTS: Patients aged older than 65 years consecutively admitted for hip fracture to the Trauma and Orthopedics Centre of a third-level hospital, between March and October 2014. METHODS: Patients were evaluated by a multidisciplinary team. A comprehensive geriatric assessment was performed on admission. Delirium was assessed before and after surgical repair according to the Confusion Assessment Method. Mortality and disability status were collected at 3 months and 1 year after hospital discharge. RESULTS: Of 411 patients with hip fracture, 387 (mean age 82 years, female 72%) were enrolled. Delirium was assessed in 50% of the enrolled population. Patients with delirium were older, frequently affected by dementia, severe prefracture disability, history of falls, and polypharmacy. One-year mortality was 19% in all populations, and higher in patients with delirium, although delirium did not show an independent association with mortality, in multivariable analysis. Conversely, delirium was identified as an independent prognostic factor of long-term disability (B-1.605, SE 0.211, P < .001). CONCLUSION AND IMPLICATIONS: This study identifies delirium as an independent long-term disability generator, regardless of associated clinical conditions and premorbid cognitive and functional status. This emphasises the importance of delirium prevention through a multidisciplinary approach and the potential role of systematic treatment of risk factors in reducing functional decline, even in subjects with preexistent disability and dementia. Moreover, these data call for research on rehabilitation interventions specifically targeted to these complex patients, with the aim of identifying approaches effective in reducing long-term disability. Conversely, a high level of clinical alertness is required in patients with delirium, as an appropriate treatment of acute diseases should reduce their high mortality risk.

Severe neurologic impairment and respiratory failure after fall and hip fracture in an elderly woman.

Fat embolism syndrome is a rare complication of long bone fractures and orthopedic surgery. We report a case of a 90-year-old woman who developed severe neurologic impairment and respiratory failure few hours after an accidental fall complicated by fracture of the left femur neck and left humerus.

The New Challenge in the Management of Proximal Femur Fractures during SARS Cov-2 outbreak.

The aim of this study is to evaluate how the spread of Sars-Cov-2 has changed the epidemiology of proximal femur fractures in two major trauma centers in Italy, understanding the workload and the best allocation of the resources for the orthopedics department in such an emergency situation. The rate of patients from January 2019 to April 2020 hospitalized with femoral neck fractures (group A) and trochanteric fractures (group B) were recorded. Demographic data, timing of surgical treatment and the length of stay were recorded. Data show that the number of proximal femur fractures has remained unchanged in the COVID and pre-COVID era (ranging from an average of 91.14/month in the pre-COVID era to 76/month in March and 80/month in April). In our trauma centers, the rate of patients operated on within 48 hours has remained stable (78.19% vs 77.92%), while the length of stay has decreased during the COVID period (8.9 days vs 6.5 days in March and 6.8 days in April). Proximal femur fractures, even during the COVID period, are a constant issue and a new challenge for the healthcare system. The main goals of management are to preserve patients from viral infection, to provide early surgical treatment and fast track protocol for discharge.

Management of ongoing direct anticoagulant treatment in patients with hip fracture.

Aim of the present study was to investigate the effects of ongoing treatment with DOACs on time from trauma to surgery and on in-hospital clinical outcomes (blood losses, need for transfusion, mortality) in patients with hip fracture. Moreover we evaluated the adherence to current guidelines regarding the time from last drug intake and surgery. In this observational retrospective study clinical records of patients admitted for hip fracture from January 2016 to January 2019 were reviewed. 74 patients were in treatment with DOACs at hospital admission. Demographic data, comorbidities and functional status before trauma were retrieved. As control group we evaluated 206 patients not on anticoagulants matched for age, gender, type of fracture and ASA score. Time to surgery was significantly longer in patients treated with DOACs (3.6 + 2.7 vs. 2.15 ± 1.07 days, p < 0.0001) and treatment within 48 h was 47% vs. 80% in control group (p < 0.0001). The adherence to guidelines' suggested time from last drug intake to surgery was 46%. Neither anticipation nor delay in surgery did result in increased mortality, length of stay or complication rates with the exception of larger perioperative blood loss (Hb levels < 8 g/dl) in DOACs patients (34% vs 9% p < 0.0001). Present results suggest that time to surgery is significantly longer in DOAC patients in comparison to controls and adherence to guidelines still limited.

TAVR in patients with hip fracture and severe aortic stenosis: how and when?

Comorbidities are common in elderly patients with hip fracture and are associated with an increased mortality after surgery. Internal medicine/geriatric leaded multidisciplinary hip fracture teams may play a pivotal role in the clinical management of complex patients. Treatment strategy is particular relevant in patients with severe aortic stenosis that represent more than 5% of patients with hip fracture. These patients have a high in-hospital mortality and poor 1-year survival (less than 50%). Transcatheter aortic valve replacement (TAVR) may be an option in selected patients; however, the choice to treat and, in the case, the timing of valve replacement in relation to hip surgery is highly dependent on clinical conditions before trauma. In this paper, three different scenario of TAVR timing after hip fracture are reported.

Postoperative atrial fibrillation is related to a worse outcome in patients undergoing surgery for hip fracture.

Few information exist about incidence and prognostic significance of postoperative atrial fibrillation (POAF) in patients undergoing hip fracture surgery. In the period comprised between January 2012 and December 2016, we evaluated 3129 patients referred for hip fracture. At hospital admission 277 were in permanent atrial fibrillation and were excluded from the study. POAF was defined as symptomatic or asymptomatic AF of duration > 10 min occurring during hospitalization after hip surgery. In-hospital and 1-year outcomes of POAF patients were compared to that of an age- and sex-matched hip fracture control group. Survival rates were estimated by Kaplan-Meier curves and differences between groups compared by log-rank test. One hundred and four patients (mean age 83.7 years, men 27%) developed POAF (3.6%). Time of onset after surgery was on average 2 days after surgery. Eight POAF patients died during hospitalization. 81.7% were discharged in sinus rhythm. Patients with POAF had a longer time to surgery (3.8 ± 3.3 vs. 2.4 ± 1.6 days, p = 0.0007) and length of hospital stay (19.7 ± 10.4 vs. 14.4 ± 5.1 days p < 0.0001) in comparison to control group. Eight patients had AF recurrence during follow-up. 1-year mortality was significantly higher in POAF group in comparison to control group (39.3. vs 20.9%, p < 0.001). Postoperative atrial fibrillation in patients undergoing hip fracture surgery is associated with a longer length of hospital stay in comparison to patients who maintain stable sinus rhythm. Moreover, these patients had a significant higher mortality at 1-year follow-up.

Low Creatinine Potentially Overestimates Glomerular Filtration Rate in Older Fracture Patients: A Plea for an Extensive Use of Cystatin C?

AIM: Muscle mass is frequently reduced in older patients experiencing injurious falls and may further reduce during hospitalization for bone fracture. In these patients, renal function may be overestimated, because it is usually calculated using serum creatinine, which is strictly related to muscle mass. We evaluated if creatinine levels change during hospitalization in older patients with fracture. We also assessed the role of cystatin C as a more appropriate marker of renal function, comparing estimated glomerular filtration rate (eGFR) according to different formulas based on creatinine and/or cystatin C levels. METHODS: Patients aged 65+ years, consecutively hospitalized for fracture, were enrolled in a prospective cohort study. Creatinine and cystatin C levels were measured at baseline and in the post-operative period; eGFR was calculated using six equations based on creatinine and/or cystatin C. RESULTS: 425 patients were enrolled (mean age 84 years, mean creatinine 0.97 mg/dL, mean cystatin C 1.53 mg/L). Creatinine levels significantly decreased after surgery (p<0.001), while cystatin C remained stable. According to creatinine-based formulas, eGFR was < 60 mL/min/1.73 m2 in 29-30% at baseline and only in 17% participants in the post-operative period. Conversely, according to equations including cystatin C, eGFR was < 60 mL/min/1.73 m2 in half to three-quarters of the sample at all assessments. CONCLUSIONS: In older fractured patients, creatinine levels decline during hospital stay and may possibly overestimate renal function, whereas cystatin C remains stable. Whether cystatin C is a more reliable marker of renal function in this specific population should be further investigated.

Perioperative Myocardial Infarction/Myocardial Injury Is Associated with High Hospital Mortality in Elderly Patients Undergoing Hip Fracture Surgery.

Cardiovascular complications in patients undergoing non-cardiac surgery are associated with longer hospital stays and higher in-hospital mortality. The aim of this study was to assess the incidence of in-hospital myocardial infarction and/or myocardial injury in patients undergoing hip fracture surgery and their association with mortality. Moreover, we evaluated the prognostic value of troponin increase stratified on the basis of peak troponin value. The electronic records of 1970 consecutive hip fracture patients were reviewed. Patients <70 years, those with myocardial infarction <30 days, and those with sepsis or active cancer were excluded from the study. Troponin and ECG were obtained at admission and then at 12, 24, and 48 h after surgery. Echocardiography was made before and within 48 h after surgery. Myocardial injury was defined by peak troponin I levels > 99th percentile. A total of 1854 patients were included. An elevated troponin concentration was observed in 754 (40.7%) patients in the study population. Evidence of myocardial ischemia, fulfilling diagnosis of myocardial infarction, was found in 433 (57%). ECG and echo abnormalities were more frequent in patients with higher troponin values; however, mortality did not differ between patients with and without evidence of ischemia. Peak troponin was between 0.1 and 1 µg/L in 593 (30.3%). A total of 191 (10%) had peak troponin I ≥ 1 µg/L, and 98 died in hospital (5%). Mortality was significantly higher in both groups with troponin increase (HR = 1.37, 95% CI 1.1-1.7, p < 0.001 for peak troponin I between 0.1 and 1 µg/L; HR = 2.28, 95% CI 1.72-3.02, p < 0.0001 for peak troponin ≥1 µg/L) in comparison to patients without myocardial injury. Male gender, history of coronary heart disease, heart failure, and chronic kidney disease were also associated with in-hospital mortality. Myocardial injury/infarction is associated with increased mortality after hip fracture surgery. Elevated troponin values, but not ischemic changes, are related to early worse outcome.
