Implications of Age for the Diagnostic and Prognostic Value of Cardiac Troponin T and I.

BACKGROUND: The influence of age on cardiac troponin is unclear and may vary between cardiac troponin T (cTnT) and I (cTnI). We aimed to compare the impact of age on the diagnostic and prognostic utility of cTnT and cTnI. METHODS: This Danish nationwide, register-based cohort study included patients with at least one cardiac troponin (cTn) measurement from 2009 through June 2022, stratified into decades of age. We used peak cTn concentration during admission, dichotomized as positive/negative and normalized to the 99th percentile. Receiver operating characteristics for myocardial infarction (MI) and logistic regression were used to estimate the odds ratio (OR) for mortality at 1 year. RESULTS: We included 541 817 patients; median age 66 years (interquartile range [IQR] 51-77) and 256 545 (47%) female. A total of 40 359 (7.4%) had an MI, and 59 800 (14.1%) patients died within 1 year of admission. The predictive ability of both cTns for MI were highest for patients 30 to 50 years. This was most pronounced for cTnT, the specificity of which fell from 83% among patients 40 to 49 years to 4% for patients ≥90 years. The prognostic ability of both cTns for 1-year mortality declined with age. cTnT had stronger prognostic ability for all age-groups; OR for a positive cTnT 28.4 (95% CI, 20.1-41.0) compared with 9.4 (95% CI, 5.0-16.7) for cTnI among patients <30 years. CONCLUSIONS: The predictive and prognostic ability of cTnT and cTnI declined with age. cTnT had a low specificity for MI in elderly patients. However, cTnT was the strongest prognostic marker among all age groups.

Ticagrelor or prasugrel vs. clopidogrel in patients with atrial fibrillation undergoing percutaneous coronary intervention for myocardial infarction.

Aims: The efficacy and safety of ticagrelor or prasugrel vs. clopidogrel in patients with atrial fibrillation (AF) on oral anticoagulation (OAC) undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI) have not been established. Methods and results: This was a nationwide cohort study of patients on OAC for AF who underwent PCI for MI from 2011 through 2019 and were prescribed a P2Y12 inhibitor at discharge. The primary efficacy outcome was major adverse cardiovascular events (MACE), defined as a composite of death from any cause, stroke, recurrent MI, or repeat revascularization. The primary safety outcome was cerebral, gastrointestinal, or urogenital bleeding requiring hospitalization. Absolute and relative risks for outcomes at 1 year were calculated through multivariable logistic regression with average treatment effect modelling. Outcomes were standardized for the individual components of the CHA2DS2-VASc and HAS-BLED scores as well as type of OAC, aspirin, and proton pump inhibitor use. We included 2259 patients of whom 1918 (84.9%) were prescribed clopidogrel and 341 (15.1%) ticagrelor or prasugrel. The standardized risk of MACE was significantly lower in the ticagrelor or prasugrel group compared with the clopidogrel group (standardized absolute risk, 16.3% vs. 19.4%; relative risk, 0.84, 95% confidence interval, 0.70-0.98; P = 0.02), while the risk of bleeding did not differ (standardized absolute risk, 5.5% vs. 5.1%; relative risk, 1.07, 95% confidence interval, 0.73-1.41; P = 0.69). Conclusion: In patients with AF on OAC who underwent PCI for MI, treatment with ticagrelor or prasugrel vs. clopidogrel was associated with reduced ischaemic risk, without a concomitantly increased bleeding risk.

Comparative outcomes in patients with preexisting heart failure to those without heart failure after out-of-hospital cardiac arrest: A nationwide registry study.

BACKGROUND: The knowledge of prognosis following out-of-hospital cardiac arrest (OHCA) in patients with heart failure heart failure (HF) is sparse. The objective of this study was to compare the outcome after OHCA among patients with and without HF. METHODS: We studied 45,293 patients who were included for the Danish cardiac arrest registry between 2001 and 2014. Patients were stratified into two groups based on the presence of HF prior to cardiac arrest. The primary outcome was 30-day survival and secondary outcome was anoxic brain damage or permanent nursing home admission at 1-year among 30-day survivors. RESULTS: Among the final 28,955 patients included, 6675 (23%) patients had prior HF and 22,280 (77%) patients had no prior HF. At 30 days, 616 (9.2%) patients survived among the patients with HF and 1916 (8.6%) among the patients without HF. There was a significant interaction between atrial fibrillation (AF) and HF for primary outcome and therefore it was assessed separately between the two study groups stratified based on AF. Among patients without AF a significantly higher odds of 30-day survival were observed among patients with HF (OR 2.69, 95% CI 2.34-3.08, P < 0.001), but no difference was observed among the patients from two study groups with no AF. No significant difference in risk for secondary outcome was observed among the two study groups. In multivariable average treatment effect modeling, all the results largely remain unchanged. CONCLUSIONS: Outcome following OHCA among patients with and without HF is found to be similar in this large Danish OHCA registry.

Serial troponin-I and long-term outcomes in subjects with suspected acute coronary syndrome.

AIMS: It is unclear how serial high-sensitivity troponin-I (hsTnI) concentrations affect long-term prognosis in individuals with suspected acute coronary syndrome (ACS). METHODS AND RESULTS: Subjects who underwent two hsTnI measurements (Siemens TnI Flex® Reagent) separated by 1-7 h, during a first-time hospitalization for myocardial infarction, unstable angina, observation for suspected myocardial infarction, or chest pain from 2012 through 2019, were identified through Danish national registries. Individuals were stratified per their hsTnI concentration pattern (normal, rising, persistently elevated, or falling) and the magnitude of hsTnI concentration change (<20%, >20-50%, or >50% in either direction). We calculated absolute and relative mortality risks standardized to the distributions of risk factors for the entire study population. A total of 20 609 individuals were included of whom 2.3% had died at 30 days, and an additional 4.7% had died at 365 days. The standardized risk of death was highest among persons with a persistently elevated hsTnI concentration (0-30 days: 8.0%, 31-365 days: 11.1%) and lowest among those with two normal hsTnI concentrations (0-30 days: 0.5%, 31-365 days: 2.6%). In neither case did relative hsTnI concentration changes between measurements clearly affect mortality risk. Among persons with a rising hsTnI concentration pattern, 30-day mortality was higher in subjects with a >50% rise compared with those with a less pronounced rise (2.2% vs. <0.1%). CONCLUSION: Among individuals with suspected ACS, those with a persistently elevated hsTnI concentration consistently had the highest risk of death. In subjects with two normal hsTnI concentrations, mortality was very low and not affected by the magnitude of change between measurements.

In this Danish study of >20 000 individuals with suspected heart attack, we confirmed the clinical importance of drawing two consecutive blood samples for measurement of high-sensitivity troponin-I concentrations (a marker of damage to the heart): The risk of death was highest in persons with two elevated high-sensitivity troponin-I concentrations and lowest in those with two normal concentrations.Among persons who had a first normal and a subsequently elevated high-sensitivity troponin-I concentration, a >50% relative rise was associated with significantly higher risk of death at 30 days.

Atrial fibrillation in patients with liver disease: Recent advances.

Atrial fibrillation is associated with significant morbidity and mortality, and its incidence is increasing globally. The primary complication of atrial fibrillation is ischemic stroke, whose risk may be reduced with oral anticoagulant agents, i.e., either vitamin K antagonists or direct oral anticoagulants. Patients with atrial fibrillation often have concomitant hepatic impairment, particularly because of increasing rates of non-alcoholic liver disease. However, anticoagulation in patients with liver disease is challenging due to the pathophysiological changes of the coagulation cascade and, as a result, an increased risk of major bleeding in such individuals. Furthermore, monitoring of the degree of anticoagulation is complicated in patients with liver disease due to issues such as spontaneous international normalized ratio (INR) elevation, changes in hepatic drug elimination, and thrombocytopenia. We review the current evidence on atrial fibrillation and anticoagulation in patients with liver disease. We suggest having a strong focus on risk factor management and argue that the risk of ischemic stroke often outweighs the risk of hemorrhagic events in this setting.

Temporal trends in socioeconomic disparity in clinical outcomes for patients with acute coronary syndrome.

AIMS: Socioeconomic factors are well-established determinants of clinical outcomes among patients with acute coronary syndrome (ACS) although quality of care has improved the last decades. This study aims to investigate 20-years temporal trends of socioeconomic disparity in 1-year incidence of major adverse cardiac events (MACE) among ACS patients in Denmark. METHODS: This population-based cohort study included all incident ACS patients in the Danish National Patient Registry during 1998-2017. Socioeconomic disparity was assessed by income and educational level. Patients were followed 1-year for MACE; defined as all-cause mortality, recurrent ACS, revascularization, stroke, or cardiac arrest. Adjusted MACE incidence rates (aIR) and hazard rate ratios (aHR) were computed with 95 % confidence intervals (CI) for five-year-periods. Changes in trends were examined from interaction analyses between the HR for five-year-periods and income and education, respectively. RESULTS: The study included 220,887 patients with first-time ACS. The incidence of MACE decreased within all income and education levels. In 1998-2002 the MACE aIR among patients with low income was 885[95%CI:863-907] versus 733[711-756]/1000-person-year among those with high income (aHR: 1.19[95%CI:1.15-1.23]). The aIRs decreased to 506[489-522] and 405[388-423]/1000-person-year, respectively, in 2013-2017 (aHR: 1.23[1.17-1.29]). The aIRs of MACE decreased correspondingly within all educational levels from 1998 to 2002 to 2013-2017. However, the socioeconomic disparity according to the interaction analyses persisted both according to income and educational level. CONCLUSION: Although 1-year clinical outcomes following ACS has improved substantially over the last decades, socioeconomic disparity persisted both according to income and education level.

Impact of postoperative intravenous iron therapy on postoperative infections in older patients with severe anaemia after hip fracture surgery.

BACKGROUND: Anaemia is common following hip fracture in ortho-geriatric patients and is associated with postoperative infections.. This study investigated whether intravenous iron supplements reduced the rate of postoperative infections within 30 days postoperatively in older adults after hip fracture surgery. METHODS: This observational study included 198 ortho-geriatric patients July 2018-May 2020. In May 2019 a local guideline was implemented and recommended II therapy on the 3rd postoperative day if haemoglobin concentration was < 6.5 mmol/L after hip fracture surgery. RESULTS: The patients were divided into four treatment groups: blood transfusion (n = 44), IV iron (n = 69), blood transfusion + IV iron (n = 35) and no treatment (n = 50). The number of patients who had an infection within 30 days was similar in the two time periods (38.8% before vs. 38.9% after systematic I.V. iron supplementation, P = 1.00) and no significant difference according to risk of infection was found between treatment groups. CONCLUSION: This study documents no effect of intravenous iron supplements on postoperative infections in older adults after hip fracture surgery. TRIAL REGISTRATION: The study was registered with the Danish Data Protection Authority (2008-58-0028) the 2th of September 2019.

All-cause admissions following a first ever exacerbation-related hospitalisation in COPD.

Background: Hospital admissions are important contributors to the overall burden of chronic obstructive pulmonary disease (COPD). Understanding the patterns and causes of hospital admissions will help to identify targets for preventive interventions. This study aimed to determine the 5-year all-cause hospital admission trajectories of patients with COPD following their first ever exacerbation-related hospitalisation. Methods: Patients with COPD were identified from the Danish national registries. Patients experiencing their first ever exacerbation-related hospitalisation, defined as the index event, between 2000 and 2014 were included. All-cause hospital admissions were examined during a subsequent 5-year follow-up period, and categorised using the International Classification of Diseases, 10th revision. Results: In total, 82 964 patients with COPD were included. The mean±sd age was 72±10 years and 48% were male. Comorbidities were present in 58%, and 65% of the patients collected inhalation medication ≤6 months prior to the index event. In total, 337 066 all-cause hospital admissions were identified, resulting in a 5-year admission rate of 82%. Most admissions were due to nonrespiratory causes (59%), amongst which cardiac events were most common (19%). Conclusion: Hospital admissions following a first exacerbation-related hospitalisation are common; nonrespiratory events constitute the majority of admissions. Besides the respiratory causes, treatment targeting the nonrespiratory causes of hospital admission should be considered to effectively decrease the burden of hospitalisation in COPD.

Electrocardiographic P terminal force in lead V1, its components, and the association with stroke and atrial fibrillation or flutter.

BACKGROUND: The electrocardiographic (ECG) marker P terminal force V1 (PTFV1) is generally perceived as a marker of left atrial pathology and has been associated with atrial fibrillation or flutter (AF). OBJECTIVE: The purpose of this study was to determine the association between PTFV1 components (duration and amplitude) and incident AF and stroke/transient ischemic attack (TIA). METHODS: The study included patients with an ECG recorded at the Copenhagen General Practitioners Laboratory in 2001 to 2011. PTFV1 ≥4 mV·ms was considered abnormal. Patients with abnormal PTFV1 were stratified into tertiles based on duration (PTDV1) and amplitude (PTAV1) values. Cox regressions adjusted for age, sex, and relevant comorbidities were used to investigate associations between abnormal PTFV1 components and AF and stroke/TIA. RESULTS: Of 267,636 patients, 5803 had AF and 18,176 had stroke/TIA (follow-up 6.5 years). Abnormal PTFV1 was present in 44,549 subjects (16.7%) and was associated with an increased risk of AF and stroke/TIA. Among patients with abnormal PTFV1, the highest tertile of PTDV1 (78-97 ms) was associated with the highest risk of AF (hazard ratio [HR] 1.37; 95% confidence interval [CI] 1.23-1.52) and highest risk of stroke/TIA (HR 1.13; 95% CI 1.05 -1.20). For PTAV1, the highest tertile (78-126 µV) conferred the highest risk of AF and stroke/TIA (HR 1.20; 95% CI 1.09-1.32; and HR 1.21; 95% CI 1.14-1.25, respectively). CONCLUSION: Abnormal PTFV1 was associated with an increased risk of AF and stroke/TIA. Increasing PTDV1 showed a dose-response relationship with the development of AF and stroke/TIA, whereas the association between PTAV1 and AF was less apparent.

Serial troponin-T and long-term outcomes in suspected acute coronary syndrome.

BACKGROUND: Long-term prognostic implications of serial high-sensitivity troponin concentrations in subjects with suspected acute coronary syndrome are unknown. METHODS AND RESULTS: Individuals with a first diagnosis of myocardial infarction, unstable angina, observation for suspected myocardial infarction, or chest pain from 2012 through 2019 who underwent two high-sensitivity troponin-T (hsTnT) measurements 1-7 h apart were identified through Danish national registries. Absolute and relative risks for death at days 0-30 and 31-365, stratified for whether subjects had normal or elevated hsTnT concentrations, and whether these concentrations changed by <20%, > 20 to 50%, or >50% in either direction from first to second measurement, were calculated through multivariable logistic regression with average treatment effect modeling. Of the 28 902 individuals included, 2.8% had died at 30 days, whereas 4.9% of those who had survived the first 30 days died between days 31-365. The standardized risk of death was highest among subjects with two elevated hsTnT concentrations (0-30 days: 4.3%, 31-365 days: 7.2%). In this group, mortality was significantly higher in those with a > 20 to 50% or >50% rise from first to second measurement, though only at 30 days. The risk of death was very low in subjects with two normal hsTnT concentrations (0-30 days: 0.1%, 31-365 days: 0.9%) and did not depend on relative or absolute changes between measurements. CONCLUSIONS: Individuals with suspected acute coronary syndrome and two consecutively elevated hsTnT concentrations consistently had the highest risk of death. Mortality was very low in subjects with two normal hsTnT concentrations, irrespective of changes between measurements.

Socioeconomic inequity in incidence, outcomes and care for acute coronary syndrome: A systematic review.

BACKGROUND: Socioeconomic inequities in acute coronary syndrome (ACS) epidemiology and care have been reported for at least 30-40 years. However, an up-to-date overview of evidence reflecting current clinical practice is not available. This systematic review aimed to summarize literature published in the last decade, regarding the association between socioeconomic position (SEP), incidence and prevalence of ACS, post-ACS medical care, and mortality. METHODS: The systematic search was performed in PubMed and Embase restricted to publication year (2009-2021), according to predefined methods (PROSPERO: CRD42020197654). Results were classified according to outcomes and socioeconomic exposures, and the risk of bias was evaluated. RESULTS: In total, 181 studies were included, mainly from high-income countries (81%). The majority showed an association between lower SEP (i.e. education, income, occupation, insurance, or composite SEP) and increased ACS incidence (89%)(incidence rate ratios: 1.1-4.7), increased ACS prevalence (88%)(odds ratios (ORs): 1.8-3.9), receiving suboptimal ACS-related medical care (46%)(ORs: 1.1-10.0), or increased post-ACS mortality (71%)(hazard rate ratios: 1.1-4.13). Studies with a lower risk of bias appeared more likely to describe inequity in favor of higher SEP than studies with a higher risk of bias. CONCLUSIONS: Across studies from the last decade, lower SEP is associated with higher risks of ACS, subsequent suboptimal medical care, and mortality among the ACS patients, in particular in studies with a lower risk of bias. This indicates considerable socioeconomic inequity among ACS patients internationally, despite low- and middle-low-income countries being inadequately represented. Thus, efforts are warranted to continuously monitor ACS-related socioeconomic inequity.

Effectiveness and safety of P2Y12 inhibitors in patients with ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention: a nationwide registry-based study.

AIMS: To compare the effectiveness and safety of clopidogrel, ticagrelor, and prasugrel in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: Nationwide, registry-based study of STEMI patients treated with primary PCI (2011-17) and subsequently with aspirin and a P2Y12 inhibitor. The effectiveness outcome was major adverse cardiovascular events (MACE) defined as a composite of recurrent myocardial infarction, repeat revascularization, stroke, or cardiovascular death at 12 months. The safety outcome was bleeding requiring hospitalization at 12 months. Multivariable logistic regression with average treatment effect modeling was used to calculate absolute and relative risks for outcomes standardized to the distributions of demographic characteristics of all included subjects. We included 10 832 patients; 1 697 were treated with clopidogrel, 7 508 with ticagrelor, and 1,627 with prasugrel. Median ages were 66, 63, and 59 years (P < 0.001). Standardized relative risks of MACE were 0.75 for ticagrelor vs. clopidogrel (95% confidence interval [CI], 0.64-0.83), 0.84 for prasugrel vs. clopidogrel (95% CI, 0.73-0.94), and 1.12 for prasugrel vs. ticagrelor (95% CI, 1.00-1.24). Standardized relative risks of bleeding were 0.77 for ticagrelor vs. clopidogrel (95% CI, 0.59-0.93), 0.89 for prasugrel vs. clopidogrel (95% CI, 0.64-1.15), and 1.17 for prasugrel vs. ticagrelor (95% CI, 0.89-1.45). CONCLUSION: Ticagrelor and prasugrel were associated with lower risks of MACE after STEMI than clopidogrel, and ticagrelor was associated with a marginal reduction compared with prasugrel. The risk of bleeding was lower with ticagrelor compared with clopidogrel, but did not significantly differ between ticagrelor and prasugrel.

Primiparous women differ from multiparous women after early discharge regarding breastfeeding, anxiety, and insecurity: A prospective cohort study.

INTRODUCTION: Breastfeeding and factors influencing breastfeeding are essential when considering the association between parity and neonatal and maternal morbidity risks when mothers are discharged within 24 hours after birth. However, there is a lack of studies examining the effect of parity and breastfeeding in a setting where all healthy mothers are recommended discharge four hours after birth. Therefore, this study examined the association between parity and the time for discharge, breastfeeding, and factors influencing breastfeeding. METHODS: The study was designed as a prospective cohort study. Data were obtained from questionnaires at one and at six weeks after birth, and combined with registered data. All 147 included mothers were healthy, with an uncomplicated birth and a healthy newborn, discharged within 24 hours after birth. RESULTS: This study documented that primiparous women had a higher relative risk (RR=2.62; 95% CI: 1.35-5.10) of having doubts about infant feeding after discharge than multiparous women. Furthermore, 54% of primiparous women contacted the maternity ward after discharge compared to 27% of multiparous women. Twice as many primiparous than multiparous women felt anxious or depressed at one and at six weeks after birth. Finally, the study documented that 13% of primiparous women and 5% of multiparous women discharged within six hours after birth perceived the time before discharge to be too short. CONCLUSIONS: Primiparous women differ from multiparous women regarding breastfeeding, insecurity, and anxiety. Special attention towards primiparous women and a follow-up strategy that allows the mothers to contact the maternity ward after early discharge is recommended.

Temporal trends in utilization of transcatheter aortic valve replacement and patient characteristics: A nationwide study.

AIM: To investigate trends in the utilization of transcatheter aortic valve replacement (TAVR) and changes in the characteristics of patients undergoing first-time TAVR. METHODS: Using Danish nationwide registers, we included all patients undergoing TAVR between 2008 and 2020. To compare patient characteristics, the study population was stratified according to calendar year of procedure: 2008-2010, 2011-2013, 2014-2016, and 2017-2020. RESULTS: We identified 6,097 patients undergoing TAVR with year-by-year increases in TAVR penetration rate. Over time, the age of the patients remained stable (2008-2010: median age 82 year [interquartile range (IQR): 77-86] vs 2017-2020: median age 81 years [IQR: 77-85]). Moreover, there was an increase in male patients (2008-2010: 49.9% vs 2017-2020: 57.4%) and patients with diabetes (2008-2010: 14.2% vs 2017-2020: 19.2%). Conversely, a history of stroke (2008-2010: 15.8% vs 2017-2020: 13.1%), previous myocardial infarction (2008-2010: 22.4% vs 2017-2020: 10.0%), heart failure (2008-2010: 40.5% vs 2017-2020: 25.2%), and peripheral artery disease (2008-2010: 14.8% vs 2017-2020: 10.4) decreased among patients. CONCLUSIONS: TAVR utilization increased markedly in the years 2008-2020. Patients undergoing TAVR had less comorbidity over time while age remained stable. Thus, despite expanding to patients at lower surgical risk, TAVR is still offered mainly to older patients.

Parenthood Rates and Use of Assisted Reproductive Techniques in Younger Hodgkin Lymphoma Survivors: A Danish Population-Based Study.

PURPOSE: The majority of young adults with Hodgkin lymphoma (HL) are cured, but chemotherapy-induced infertility can have profound psychosocial consequences. Providing data on parenthood rates and use of assisted reproductive techniques (ARTs) after contemporary HL treatment is important for patient counseling and survivorship care. MATERIALS AND METHODS: All Danish patients with HL diagnosed during 2000-2015 at the ages 18-40 years who achieved remission after first-line therapy were included and matched on age, sex, and parenthood status to five random persons from the general population. Parenthood rates were defined as the rate of first live birth per 1,000 person years, starting 9 months after HL diagnosis. Nationwide birth and patient registers were used to capture parenthood outcomes and ARTs use. RESULTS: A total of 793 HL survivors and 3,965 comparators were included (median follow-up 8.7 years). Similar parenthood rates were observed for male and female HL survivors when compared with matched comparators (56.2 v 57.1; P = .871 for males and 63.8 v 61.2; P = .672 for females). For male HL survivors, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) therapy was associated with lower parenthood rates as compared to the matched comparators (28.1 v 60.8; P = .020). Live birth after ARTs were more common for HL survivors than for comparators (males 21.6% v 6.3%; P < .001; females 13.6% v 5.5%; P = .001). There were no differences in gestational age, Apgar score, or newborn measurements between HL survivors and matched comparators. CONCLUSION: The parenthood rates for HL survivors who have not experienced relapse were generally similar to the general population. However, ARTs were used more often before the first live birth in HL survivors, which is relevant information when discussing possible long-term side effects and fertility-preserving treatment options.

Association between intravenous iron therapy and short-term mortality risk in older patients undergoing hip fracture surgery: an observational study.

BACKGROUND: Anemia is common among ortho-geriatric hip fracture patients and is associated with prolonged recovery and increased postoperative mortality rate. Intravenous iron seems to increase hemoglobin recovery and reduce the mortality rate in patients undergoing orthopedic surgeries. This study investigated the association between short-term mortality risk and intravenous iron therapy in older patients undergoing hip fracture surgery. METHODS: This observational study included 210 patients undergoing hip fracture surgery from July 2018 to May 2020. These 210 patients were alive and had a hemoglobin ≤ 6.5 mmol/L on the 3rd postoperative day. In May 2019, a local intravenous iron therapy protocol was implemented and recommended intravenous iron (Monofer©) if hemoglobin on the 3rd postoperative day was ≤ 6.5 mmol/L. According to the treatment of postoperative anemia between the 1st and 3rd day post-surgery, the patients were divided into four groups: no treatment (n=52), blood transfusion (n=38), IV Monofer (n=80), and blood transfusion and IV Monofer (n=40). Primary outcome was 30-day mortality post-surgery. The secondary outcome was the impact on hemoglobin level 14-30 days postoperatively. Multivariable Cox regression was used to estimate the 30-day mortality standardized for covariates. RESULTS: Of 210 patients, 17 (8.1%) died within 30 days after surgery. There was a significantly lower mortality among the patients who received IV Monofer compared to those who received no treatment (HR 0.17, 95% CI [0.03-0.93], P = 0.041). Among the 86 patients with available hemoglobin measurements within 14 to 30 days post-surgery, there was no significant difference in hemoglobin level between the various treatment groups (mean 6.6 mmol/L, P = 0.1165). CONCLUSION: IV Monofer on the 3rd postoperative day in older hip fracture patients seemed to reduce 30-day mortality compared with no treatment. No significant differences in hemoglobin levels between 14 and 30 days post-surgery across treatment groups were found, although this was assessed in a subset of patients with available hemoglobin levels warranting further study.

Venous thromboembolism after lower extremity orthopedic surgery: A population-based nationwide cohort study.

BACKGROUND: Venous thromboembolism (VTE) causes morbidity and mortality in the general population. Several events occur after lower limb orthopedic surgery, but the contribution from various types of lower limb surgery is not well known. OBJECTIVE: To investigate the postoperative incidence of VTE for all types of lower extremity orthopedic surgery compared with the background population. METHODS: Individual-level linkage of Danish nationwide register data for all Danish residents with first-time orthopedic surgery of the lower limb (1996-2017) and, for each of these, four controls from the general population matched on age, sex, and history of VTE. Adjusted hazard ratios (HR) compared the postoperative risk of VTE to the matched controls. RESULTS: In total 7203 of the 1 012 823 patients with a first orthopedic procedure had a VTE within 180 days after surgery, corresponding to a postoperative cumulative incidence of 0.71% (95% confidence interval [CI], 0.70-0.73). The cumulative incidence of VTE among controls was 0.11% (95% CI, 0.11-0.12). The HR of VTE within the first 30 days after surgery below knee level was 20.5 (95% CI, 17.9-23.5) compared with matched controls. The HRs of VTE after minor distal procedures (eg, meniscectomy and arthroscopies) were 2.9 (95% CI, 1.9-4.4) to 7.1 (95% CI, 6.4-8.0). CONCLUSION: All types of lower limb orthopedic surgery including minor distal procedures were associated with higher rates of VTE compared with matched controls, in particular within the first 30 days after surgery.

Validity of the GAITRite Walkway Compared to Functional Balance Tests for Fall Risk Assessment in Geriatric Outpatients.

This study examined the concurrent validity between gait parameters from the GAITRite walkway and functional balance test commonly used in fall risk assessment. Patients were sampled from one geriatric outpatient clinic. One physiotherapist evaluated the patients on the GAITRite walkway with three repetitions in both single- and dual-task conditions. Patients were further evaluated with Bergs Balance scale (BBS), Dynamic Gait index (DGI), Timed Up and Go (TUG), and Sit To Stand test (STS). Correlations between quantitative gait parameters and functional balance test were analyzed with Spearman's rank correlations. Correlations strength was considered as follows: negligible <0.1, weak 0.10-0.39, moderate 0.40-0.69, and strong ≥0.70. We included 24 geriatric outpatients in the study with a mean age of 80.6 years (SD: 5.9). Patients received eight (SD: 4.5) different medications on average, and seven (29.2%) patients used walkers during ambulation. Correlations between quantitative gait parameters and functional balance test ranged from weak to moderate in both single- and dual-task conditions. Moderate correlations were observed for DGI, TUG, and BBS, while STS showed weak correlations with all GAITRite parameters. For outpatients analyzed on the GAITRite while using walkers, correlations showed no clear pattern across parameters with large variation within balance tests.

Depression and anxiety in Hodgkin lymphoma patients: A Danish nationwide cohort study of 945 patients.

Cancer-related psychological distress may lead to depression and anxiety among survivors. The vast majority of patients with Hodgkin lymphoma (HL) become long-term survivors, but the risk of mental health problems after HL is not well-characterized. Using national population-based registries, we investigated the cumulative incidence of psychotropic drug (antidepressants, antipsychotics, and anxiolytics) use (proxies for depression and anxiety) in HL patients as well as if an increased risk would normalize over time for patients in remission. The study included 945 HL patients aged 18-92 years and 4725 matched persons. In total, 215 HL patients (22.8%) received a prescription of any psychotropic drug (PD) at some point after date of diagnosis compared to 545 persons (11.5%) in the matched cohort. Cumulative incidences with death/relapse as competing risk confirmed that HL patients were at higher risk of receiving psychotropic drug prescriptions, but the increased risk was transient and normalized to the matched population 5 years into survivorship. Increased age, Eastern Cooperative Oncology Group performance status, and disease stage were associated with higher risk of psychotropic drug prescriptions. Given the increased rate of psychotropic drug prescriptions after HL diagnosis, screening for symptoms of depression and anxiety is warranted after HL diagnosis and first years into survivorship.
