RESUMO
BACKGROUND: Trochanteric bursitis (TB) is a prevalent complication following total hip arthroplasty (THA), with increased offset hypothesized as a potential risk factor. This study investigated potential TB predictors in THA patients, including radiographic measurements of offset and leg length, comorbidities, and patient characteristics. METHODS: In this retrospective cohort study, all THA patients from a single academic tertiary care center between 2005 and 2021 were reviewed. Exclusion criteria included less than one-year follow-up, osteonecrosis, or fracture. Manual radiographic measurements of offset (acetabular, femoral, and total) and leg length from preoperative and postoperative antero-posterior pelvis X-rays were taken, with scaling using femoral cortical diameter. Univariable and multivariable Cox proportional hazard models were employed to estimate TB risk. RESULTS: Of 1,094 patients, 103 (9.4%) developed TB, with a median (Q1, Q3) time to presentation of 41.8 weeks (25.5, 66.9). In univariable models, only sex was associated with increased TB risk, with women exhibiting a 1.79 times increased risk (hazard ratio: 1.79 (1.16, 2.76), P = .009). Changes in acetabular offset, femoral offset, total offset, and leg length between preoperative and postoperative radiographs were not associated with an increased risk of developing TB in the univariate or multivariate models. Furthermore, various offset thresholds were evaluated, with no amount of increased offset showing increased TB risk. CONCLUSIONS: This study found no relationship between femoral, acetabular, or total offset and TB following THA. These findings suggest that surgeons may consider adding offset for increased prosthetic stability in high-risk cases. However, given that this is a retrospective study, the authors are not advocating for the routine use of increased offset. The study identified women as a risk factor with a 1.79 times higher TB risk, highlighting the importance of counseling women patients on this heightened risk.
RESUMO
OBJECTIVE: To describe the function of patients with COVID-19 admitted to an acute care hospital early in the pandemic and to characterize change in function among those admitted to intensive care units (ICU) and to non-critical care services. DESIGN: This descriptive, retrospective cohort study examined patients infected with SARS-CoV-2 admitted to a tertiary care medical center during the first wave of the pandemic in 2020. Included patients were stratified into 4 cohorts based on whether or not they received therapy during their hospitalization and whether or not their hospitalization included time in the ICU. Data on demographic characteristics, functional impairments, medical interventions, and functional outcomes were collected. SETTING: Hospital. PARTICIPANTS: 432 adult patients were included in this study (N=432). RESULTS: ICU patients receiving therapy were more likely to have impaired cognition, impaired strength, and impaired sensation than non-ICU patients receiving therapy. Patients made improvements from evaluation to discharge on the Functional Status Score for the ICU, Activity Measure for Post-Acute Care Daily Activity, and AM-PAC Basic Mobility Short Forms. CONCLUSION: Patients admitted with COVID-19 experienced significant functional impairments but also demonstrated improvement during the course of their hospitalizations. This study can facilitate health care provider awareness of the detrimental functional effects of COVID-19 and the potential role of rehabilitation services for these patients.

BACKGROUND: Although the risk of extremity amputation related to an isolated vascular injury is low, it increases significantly with concomitant orthopedic injury. Our study aims to evaluate and quantify the impact of risk factors associated with trauma-related extremity amputation in patients with vascular injury. We sought to determine whether there are other potential predictors of amputation. METHODS: A retrospective review of patients with extremity vascular injury presenting to a single level 1 academic trauma center between January 1, 2007, and December 31, 2018, was performed. All patients diagnosed with major vascular injury to the upper or lower extremity were included. Data on patient demographics, medical comorbidities, anatomic location of vascular injury, and the presence of soft tissue or orthopedic injury were collected. The main outcome measure was major amputation of the affected extremity. Major amputation included below-the-knee amputation, above-the-knee amputation, as well as any amputation of the upper extremity at or proximal to the wrist. RESULTS: We identified 250 extremities with major vascular injury in 234 patients. Of these, 216 (86.4%) were male and 34 (13.6%) female. The mean age was 32.2 years (range 18-79 years) and mean follow-up was 6.9 (standard deviation: 3.3) years. Just over half of injuries, 130 (52.0%) involved the lower extremity. Forty extremities (29 lower and 11 upper), or 16.0%, of total injured extremities, required major amputation during the follow-up period. Concomitant orthopedic injury was present in 106 of 250 (42%) injured extremities. Using univariable logistic regression models, variables with a significant association with major amputation included older age, higher body mass index, blunt mechanism of injury, concomitant orthopedic injury, soft tissue injury, and nerve injury, and the need for fasciotomy (P < 0.05). In multivariable analyses, blunt mechanism of injury (odds ratio [OR] (confidence ratio {CI}): 6.51 (2.29, 18.46), P < 0.001) and concomitant orthopedic injury (OR [CI]: 7.23 [2.22, 23.55], P = 0.001) remained significant predictors of amputation. CONCLUSIONS: Concomitant orthopedic injury and blunt mechanism in the setting of vascular injury are associated with a higher likelihood of amputation in patients with extremity vascular injury. Further development of a vascular extremity injury protocol may be needed to enhance limb salvage. Findings may guide patient discussion regarding limb-salvage decision-making.

Objective: To examine disparities between primary care provider (PCP) and gastroenterologist diagnosis and management of irritable bowel syndrome (IBS).Design: Retrospective cross-sectional study.Setting: A 547-bed quaternary-care hospital within the Loyola University Healthcare System.Participants: 1000 patients aged 18-65 with an ICD-10 diagnosis of IBSMethods: We randomly selected 1000 patients aged 18 to 65 years within the Loyola University Healthcare System's electronic medical record with an ICD-10 diagnosis of IBS. Physician notes and diagnostic results were reviewed for documentation of symptoms fulfilling Rome IV criteria and resolution of symptoms. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of primary diagnoses assigned by PCPs and gastroenterologists were assessed along with number of diagnostic tests ordered.Results: The mean age (SD) was 45 (12) years, and 76.9% were female. Sensitivity of an IBS diagnosis by a PCP was 77.6% (95% CI 73.3-81.9), compared with 60.1% (95% CI 54.7-65.6) for a gastroenterologist. Specificity of an IBS diagnosis by a PCP was 27.5% (95% CI 23.5-31.5), compared with 71.1% (95% CI 64.6-77.5) for a gastroenterologist diagnosis of IBS. A gastroenterologist diagnosis of IBS carried a high PPV (77.3%, 95% CI 72.0-82.6) compared with 44.6% (95% CI 40.7-48.5) for a PCP. Of 180 patients with outcome data, 69.4% had resolution of symptoms at follow-up.Conclusion: The sensitivity of gastroenterologist diagnosis of IBS closely matches the sensitivity of Rome IV criteria in validation studies. The high specificity and PPV of gastroenterologists suggest more cautious diagnosis by gastroenterologists, with PCPs more likely to assign a diagnosis of IBS incorrectly or without sufficient documentation of symptoms fulfilling Rome IV criteria. Reported resolution rates suggest primary care management of IBS is appropriate, but PCPs may benefit from gastroenterologist consultation and diagnostic guidelines for greater specificity in diagnosing IBS.

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of cancer and cancer-related mortality worldwide. Studies have suggested that aspirin (ASA) and statins may be associated with a decrease in incident HCC. GOALS: We aimed to evaluate the effect of ASA and statin use on the incidence of HCC in a prospective cohort of patients with liver cirrhosis and to identify if there was an increased risk of esophageal variceal hemorrhage (VH) in patients with ASA use. STUDY: We conducted a retrospective study of 521 patients with data collected from July 1, 2012 to December 31, 2017. We used competing risk analysis to assess the association between risk factors and HCC; and the association between ASA and VH. RESULTS: ASA use alone was associated with a decreased incidence of HCC in the univariate and multivariate models; [hazard ratio (HR) confidence interval (CI): 0.348 (0.124-0.976); P=0.0448] and [HR (CI): 0.266 (0.094-0.755); P=0.0129, respectively]. The combination of ASA and statin use was associated with a decreased hazard of HCC [HR (CI): 0.15 (0.036-0.624); P=0.0090] and this remained statistically significant in the multivariable model [HR (CI): 0.113 (0.026-0.483); P=0.0033]. Among daily ASA users compared with non-users, there was not a significant increase in risk of VH. CONCLUSIONS: Daily ASA use was associated with a decrease risk of incident HCC. The combination of daily ASA use and statin use decreased the risk of incident HCC suggesting there is beneficial interaction. Finally, no excess VH was observed in daily ASA users compared with non-users.

INTRODUCTION: Aortic neck dilation post endovascular aneurysm repair (EVAR) has been implicated in the long-term development of endoleak and the subsequent re-intervention. Optimal endograft sizing is a vital aspect to successful repair. This study looked at percentage of graft oversizing as well as type of fixation on aortic neck dilation. METHODS: We retrospectively evaluated all EVARs completed at Loyola's University from 2006 to 2015 after IRB approval. Patients without follow-up scans within a year were excluded. We collected demographics, comorbidities, graft type, size, aortic neck diameter, maximum sac size diameters from the pre-operative and follow-up scans. We reviewed and collected data on 432 patients but analyzed 154. We measured the largest aortic diameter on axial images 1 cm above and 1 cm below the lowest renal artery. Change in supra and infrarenal aortic measurements were evaluated by calculating the mm difference from each scan compared to the pre-operative scan. Linear mixed effects models were used to estimate patients' mean differences over time. RESULTS: We compared three groups of neck fixation grafts. Those with active suprarenal fixation had a significant change in suprarenal aortic diameter at four-year follow-up (1.86 mm, CI:0.65-3.06), compared to those with active infrarenal (0.22 mm, CI: -0.67 to -1.11) or passive suprarenal fixation (1.52 mm, CI: -0.11 to -3.15) (Fig. 1). Those with active suprarenal fixation were the only ones to have significant increase in suprarenal aortic diameter (P = 0.0026). Degree of oversizing was also divided into three groups. Oversizing by <10% had less impact on the suprarenal aorta than >15% oversizing at 4 years (0.41 mm, CI: -0.31 to -1.14 vs. 3.26 mm, CI: 1.63-4.88, P < 0.001) (Fig. 2). Oversizing had a more pronounced effect on the infrarenal aorta: 3.01 mm, CI: 2.18-3.83; 5.95 mm, CI: 3.26-8.64; and 5.05 mm, CI: 3.41-6.69 for <10%, 10-15%, and >15% oversizing at four years, respectively. CONCLUSION: Stent-grafts with active fixation below the renal arteries as well as oversizing by <10% seem to have the least effect on aortic neck dilation over time. These factors should be considered when performing EVARs, as aortic neck dilation could lead to endoleak and need for further intervention. Further research defining the optimal stent-graft type, self-expanding versus balloon expandable, type of fixation and degree of oversizing.

BACKGROUND: The primary objective of this study is to assess the risk of thromboembolic events (TEs) in hospitalized patients with coronavirus disease 2019 (COVID-19) and study the impact of TEs on hospital course and mortality risk during the initial height of the severe acute respiratory syndrome coronavirus-2 pandemic. METHODS: A retrospective review of all adult inpatients (≥ 18 years old) with COVID-19 infection at a single academic institution from March 15, 2020 to July 1, 2020 was performed. Collected data included patient demographics, comorbidities, hospital admission type, TEs, laboratory values, use of anticoagulants/antiplatelet agents, hospital length of stay, and in-hospital mortality. A logistic regression was used to estimate associations between risk factors and TEs. RESULTS: A total of 826 inpatients with COVID-19 were identified. Of these, 56% were male, average age was 60.9 years, and race/ethnicity was reported as Hispanic in 51%, non-Hispanic Black in 25%, and non-Hispanic White in 18%. A total of 98 TEs were documented in 87 patients (10.5%). Hypertension, coronary artery disease, and chronic limb threatening ischemia were associated with an increased incidence of thromboembolism (P < 0.05). Hispanic patients had higher incidence of thromboembolism compared to White non-Hispanic patients (odds ratio {[OR] confidence interval [CI]}: 2.237 [1.053, 4.754], P = 0.036). As D-dimer increased, the odds of TE increased by 5.2% (OR [CI]: 1.052 [1.027, 1.077], P < 0.001). Patients with TEs had longer hospital stay (median 13 vs. 6 days, P < 0.001), higher likelihood of intensive care unit admission (63% vs. 33%, P < 0.001), and higher in-hospital mortality (28% vs. 16%, P = 0.006). Arterial TEs were associated with higher in-hospital mortality than venous TEs (37% vs. 15%, P = 0.027). CONCLUSIONS: During the initial height of the severe acute respiratory syndrome coronavirus-2 pandemic, TEs were relatively frequent in hospitalized patients with COVID-19. Racial disparities were seen with an increased proportion of minority patients admitted with respect to percentages seen in the general population. There was also a significantly increased incidence of TEs in Hispanic patients. TEs were associated with significantly longer hospital stay and higher in-hospital mortality. Patients with arterial TEs fared worse with significantly higher mortality than those with venous events. Inconsistencies in anticoagulation management early in the pandemic may have contributed to poor outcomes and more contemporary management outcomes need to be investigated.

PURPOSE: Smoking is a major public health issue, and its effect on cardiovascular outcomes is well established. This study evaluates the impact of donor smoking on heart transplant (HT) outcomes. METHODS: HT recipients between January 1, 2005, and December 31, 2016, with known donor smoking status were queried from the International Society of Heart and Lung Transplantation (ISHLT) registry. The primary outcome was all-cause mortality, and secondary endpoints were graft failure, acute rejection, and cardiac allograft vasculopathy. We utilized propensity-score matching to identify cohorts of recipients with and without a history of donor smoking. Hazard ratios for post-transplant outcomes for the matched sample were estimated from separate Cox proportional hazard models. RESULTS: Of 26 390 patients in the cohort, 18.9% had history of donor smoking. Donors with history of smoking were older, predominantly male and had higher incidence of diabetes, hypertension, cocaine use, and "high-risk" status. In propensity-matched analysis, recipients with a history of donor smoking had increased risk of death (HR 1.11, 95% CI 1.03-1.20) and higher risk of graft failure (HR 1.11, 95% CI 1.03-1.20). CONCLUSION: Donor smoking was associated with increased mortality and higher incidence of graft failure following HT. Consideration of donor smoking history is warranted while evaluating donor hearts.

BACKGROUND: Protecting the pediatric population from unnecessary medical radiation is an important public health initiative. Efforts have been made to reduce radiation exposure in the treatment of pediatric fractures without compromising quality of care. Using a standardized protocol for imaging of pediatric clavicle and metatarsal fractures is a reliable method for reducing pediatric radiation exposure in the management of these fractures. METHODS: In the year 2015, the senior author altered follow-up imaging practices for 2 common pediatric fractures: metatarsal and clavicular. Initial radiographic evaluation included the standard 3 views for metatarsal fractures and 2 views for clavicle fractures. This standard diagnostic procedure remained constant throughout the study. Follow-up x-rays from 2009 to 2014 routinely included 3 views of the foot and 2 views of the clavicle. The protocol was changed and from 2016 to 2019, follow-up x-rays for fractures routinely included 2 views of the foot and 1 view of the clavicle, thereby decreasing the number of x-rays utilized to manage these fractures. RESULTS: There was a significant reduction in the number of clavicle x-rays (P<0.001) and metatarsal x-rays (P=0.004) taken in follow-up between the time-periods. Median values for metatarsal views decreased by 1, matching the adjustment in protocol. In addition, the vast majority of clavicle fractures (90.80%) were managed with 1 follow-up view in 2016 to 2019 compared with 2 views (72.48%) from 2009 to 2014. CONCLUSIONS: This study achieved a reduction in radiation exposure in pediatric patients with nonoperatively managed clavicle and metatarsal fractures. Improving the quality of care of patients through decreasing the number of x-rays taken protects individuals from adverse side effects, as well as offers various public health benefits in terms of reduction in expenditures. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

BACKGROUND: Brain arteriovenous malformations (AVMs) consist of abnormal connections between arteries and veins via an interposing nidus. While hemorrhage is the most common presentation, unruptured AVMs can present with headaches, seizures, neurological deficits, or be found incidentally. It remains unclear as to what AVM characteristics contribute to pain generation amongst unruptured AVM patients with headaches. METHODS: To assess this relationship, the current study evaluates angiographic and clinical features amongst patients with unruptured brain AVMs presenting with headache. Loyola University Medical Center medical records were queried for diagnostic codes corresponding to AVMs. In patients with unruptured AVMs, we analyzed the correlation between the presenting symptom of headache and various demographic and angiographic features. RESULTS: Of the 144 AVMs treated at our institution between 1980 and 2017, 76 were unruptured and had sufficient clinical data available. Twenty-three presented with headaches, while 53 patients had other presenting symptoms. Patients presenting with headache were less likely to have venous stenosis compared to those with a non-headache presentation (13 % vs. 36 %, p = 0.044). CONCLUSIONS: Our study suggests that the absence of venous stenosis may contribute to headache symptomatology. This serves as a basis for further study of correlations between AVM angioarchitecture and symptomatology to direct headache management in AVM patients.

BACKGROUND: To evaluate participant-related variables associated with missing assessment(s) at follow-up visits during a longitudinal research study. METHODS: This is a prospective, longitudinal, multi-site study of 196 acute respiratory distress syndrome (ARDS) survivors. More than 30 relevant sociodemographic, physical status, and mental health variables (representing participant characteristics prior to ARDS, at hospital discharge, and at the immediately preceding follow-up visit) were evaluated for association with missed assessments at 3, 6, 12, and 24-month follow-up visits (89-95% retention rates), using binomial logistic regression. RESULTS: Most participants were male (56%), white (58%), and ≤ high school education (64%). Sociodemographic characteristics were not associated with missed assessments at the initial 3-month visit or subsequent visits. The number of dependencies in Activities of Daily Living (ADLs) at hospital discharge was associated with higher odds of missed assessments at the initial visit (OR: 1.26, 95% CI: 1.12, 1.43). At subsequent 6-, 12-, and 24 months visits, post-hospital discharge physical and psychological status were not associated with subsequent missed assessments. Instead, the following were associated with lower odds of missed assessments: indicators of poorer health prior to hospital admission (inability to walk 5 min (OR: 0.46; 0.23, 0.91), unemployment due to health (OR: 0.47; 0.23, 0.96), and alcohol abuse (OR: 0.53; 0.28, 0.97)) and having the preceding visit at the research clinic rather than at home/facility, or by phone/mail (OR: 0.54; 0.31, 0.96). Inversely, variables associated with higher odds of missed assessments at subsequent visits include: functional dependency prior to hospital admission (i.e. dependency with > = 2 Instrumental Activities of Daily Living (IADLs) (OR: 1.96; 1.08, 3.52), and missing assessments at preceding visit (OR: 2.26; 1.35, 3.79). CONCLUSIONS: During the recovery process after hospital discharge, dependencies in physical functioning (e.g. ADLs, IADLs) prior to hospitalization and at hospital discharge were associated with higher odds of missed assessments. Conversely, other indicators of poorer health at baseline were associated with lower odds of missed assessments after the initial post-discharge visit. To reduce missing assessments, longitudinal clinical research studies may benefit from focusing additional resources on participants with dependencies in physical functioning prior to hospitalization and at hospital discharge.

BACKGROUND: Prior randomised trials have evaluated statins in patients with sepsis and acute respiratory distress syndrome (ARDS), but there has been no comprehensive evaluation of long-term effects, despite potential neuromuscular and mental health adverse effects of these drugs. AIM: To evaluate the effect of rosuvastatin versus placebo on survival, physical function and performance, and mental health outcomes in patients with sepsis-associated ARDS. METHODS: Prospective follow-up evaluation of the ARDS Clinical Trials Network Statins for Acutely Injured Lungs from Sepsis trial of rosuvastatin versus placebo in 568 mechanically ventilated patients with sepsis-associated ARDS, with blinded 6-month outcome assessment performed in the 272 eligible survivors for age-adjusted and sex-adjusted 36-Item Short Form Health Survey (SF-36) physical function and mental health domains, and in 84 eligible survivors for the 6â min walk test, along with secondary outcomes evaluations of survival, and additional patient-reported and performance-based measures at 6-month and 12-month follow-up. RESULTS: Over 1-year follow-up, there was no significant difference in cumulative survival in the rosuvastatin versus placebo groups (58% vs 61%; p=0.377), with survivors demonstrating substantial impairments in physical function and mental health. Rosuvastatin versus placebo had no effect (mean treatment effect (95% CI)) on SF-36 physical function (0 (-7 to 8), p=0.939) or mental health (-6 (-12 to 1) p=0.085) domains, 6â min walk distance (per cent predicted: 2 (-9 to 14), p=0.679) or the vast majority of secondary outcomes. CONCLUSIONS: Over 1-year follow-up, patients with sepsis-associated ARDS had high cumulative mortality, with survivors commonly experiencing impairments in physical functioning and performance, and mental health. Randomisation to rosuvastatin had no effect on these outcomes. TRIAL REGISTRATION NUMBER: NCT00979121 and NCT00719446.

INTRODUCTION: Patients receiving intravenous thrombolysis with recombinant tissue plasminogen activator (IVT) for ischemic stroke are monitored in an intensive care unit (ICU) or a comparable unit capable of ICU interventions due to the high frequency of standardized neurological exams and vital sign checks. The present study evaluates quantitative infarct volume on early post-IVT MRI as a predictor of critical care needs and aims to identify patients who may not require resource intense monitoring. METHODS: We identified 46 patients who underwent MRI within 6 h of IVT. Infarct volume was measured using semiautomated software. Logistic regression and receiver operating characteristics (ROC) analysis were used to determine factors associated with ICU needs. RESULTS: Infarct volume was an independent predictor of ICU need after adjusting for age, sex, race, systolic blood pressure, NIH Stroke Scale (NIHSS), and coronary artery disease (odds ratio 1.031 per cm(3) increase in volume, 95% confidence interval [CI] 1.004-1.058, p = 0.024). The ROC curve with infarct volume alone achieved an area under the curve (AUC) of 0.766 (95% CI 0.605-0.927), while the AUC was 0.906 (95% CI 0.814-0.998) after adjusting for race, systolic blood pressure, and NIHSS. Maximum Youden index calculations identified an optimal infarct volume cut point of 6.8 cm(3) (sensitivity 75.0%, specificity 76.7%). Infarct volume greater than 3 cm(3) predicted need for critical care interventions with 81.3% sensitivity and 66.7% specificity. CONCLUSION: Infarct volume may predict needs for ICU monitoring and interventions in stroke patients treated with IVT.

RATIONALE: Existing studies of risk factors for physical impairments in acute lung injury (ALI) survivors were potentially limited by single-center design or relatively small sample size. OBJECTIVES: To evaluate risk factors for three measures of physical impairments commonly experienced by survivors of ALI in the first year after hospitalization. METHODS: A prospective, longitudinal study of 6- and 12-month physical outcomes (muscle strength, 6-minute-walk distance, and Short Form [SF]-36 Physical Function score) for 203 survivors of ALI enrolled from 12 hospitals participating in the ARDS Network randomized trials. Multivariable regression analyses evaluated the independent association of critical illness-related variables and intensive care interventions with impairments in each physical outcome measure, after adjusting for patient demographics, comorbidities, and baseline functional status. MEASUREMENTS AND MAIN RESULTS: At 6 and 12 months, respectively, mean (± SD) values for strength (presented as proportion of maximum strength score evaluated using manual muscle testing) was 92% (± 8%) and 93% (± 9%), 6-minute-walk distance (as percent-predicted) was 64% (± 22%) and 67% (± 26%), and SF-36 Physical Function score (as percent-predicted) was 61% (± 36%) and 67% (± 37%). After accounting for patient baseline status, there was significant association and statistical interaction of mean daily dose of corticosteroids and intensive care unit length of stay with impairments in physical outcomes. CONCLUSIONS: Patients had substantial impairments, from predicted values, for 6-minute-walk distance and SF-36 Physical Function outcome measures. Minimizing corticosteroid dose and implementing existing evidence-based methods to reduce duration of intensive care unit stay and associated patient immobilization may be important interventions for improving ALI survivors' physical outcomes.

BACKGROUND: Quisinostat (JNJ-26481585) is a second-generation pyrimidyl-hydroxamic acid histone deacetylase (HDAC) inhibitor with high cellular potency towards Class I and II HDACs. Quisinostat was selected for clinical development as it showed prolonged pharmacodynamic effects in vivo and demonstrated improved single agent antitumoral efficacy compared to other analogs. PROCEDURES: Quisinostat was tested against the PPTP in vitro panel at concentrations ranging from 1.0 nM to 10 µM and was tested against the PPTP in vivo panels at a dose of 5 mg/kg (solid tumors) or 2.5 mg/kg (ALL models) administered intraperitoneally daily × 21. RESULTS: In vitro quisinostat demonstrated potent cytotoxic activity, with T/C% values approaching 0% for all of the cell lines at the highest concentration tested. The median relative IC50 value for the PPTP cell lines was 2.2 nM (range <1-19 nM). quisinostat induced significant differences in EFS distribution compared to control in 21 of 33 (64%) of the evaluable solid tumor xenografts and in 4 of 8 (50%) of the evaluable ALL xenografts. An objective response was observed in 1 of 33 solid tumor xenografts while for the ALL panel, two xenografts achieved complete response (CR) or maintained CR, and a third ALL xenograft achieved stable disease. CONCLUSIONS: Quisinostat demonstrated broad activity in vitro, and retarded growth in the majority of solid tumor xenografts studied. The most consistent in vivo activity signals observed were for the glioblastoma xenografts and T-cell ALL xenografts.

RATIONALE: We hypothesized that providing patients with acute lung injury two different protein/calorie nutritional strategies in the intensive care unit may affect longer-term physical and cognitive performance. OBJECTIVES: To assess physical and cognitive performance 6 and 12 months after acute lung injury, and to evaluate the effect of trophic versus full enteral feeding, provided for the first 6 days of mechanical ventilation, on 6-minute-walk distance, cognitive impairment, and secondary outcomes. METHODS: A prospective, longitudinal ancillary study of the ARDS Network EDEN trial evaluating 174 consecutive survivors from 5 of 12 centers. Blinded assessments of patients' arm anthropometrics, strength, pulmonary function, 6-minute-walk distance, and cognitive status (executive function, language, memory, verbal reasoning/concept formation, and attention) were performed. MEASUREMENTS AND MAIN RESULTS: At 6 and 12 months, respectively, the mean (SD) percent predicted for 6-minute-walk distance was 64% (22%) and 66% (25%) (P = 0.011 for difference between assessments), and 36 and 25% of survivors had cognitive impairment (P = 0.001). Patients performed below predicted values for secondary physical tests with small improvement from 6 to 12 months. There was no significant effect of initial trophic versus full feeding for the first 6 days after randomization on survivors' percent predicted for 6-minute-walk distance, cognitive impairment status, and all secondary outcomes. CONCLUSIONS: EDEN trial survivors performed below predicted values for physical and cognitive performance at 6 and 12 months, with some improvement over time. Initial trophic versus full enteral feeding for the first 6 days after randomization did not affect physical and cognitive performance.

Effective perioperative pain control following knee arthroscopy allows patients to reduce narcotic intake, avoid side effects of these medications, and recover more quickly. Adductor canal nerve blockade (ACB) and intra-articular injection of local anesthetic have been described as adjuvant treatments for postoperative pain control following surgery of the knee. This study directly compares the effect of each of these treatment modalities. Patients undergoing knee arthroscopy were blinded and randomized to receive either an ACB (n = 60) or intra-articular injection of local anesthetic (IAB, n = 64). Outcome measures included patient reported visual analog scale (VAS) scores at 1, 2, 4, 8, 16, 24, 36, 48 hours and 1 week and total narcotic consumption at 12, 24, and 48 hours postoperatively. Student's t-tests were used to compare unadjusted VAS scores at each time point and use of postoperative pain medication between treatment groups. Adjusted VAS scores were estimated in a multivariable general linear model with interaction of time and treatment group and other relevant covariates. There were no statistically significant differences between the two groups in terms of gender, age, body mass index, and insurance type. ACB patients had significantly higher pain scores than IAB patients at hours 1 and 2 (hour 1: 4.02 [2.99] vs. 2.59 [3.00], p = 0.009; hour 2: 3.12 [2.44] vs. 2.17 [2.62], p = 0.040). ACB patients had higher pain scores than IAB patients up to hour 16, though hours 4 to 16 were not significantly different. Adjusted covariate analyses demonstrate an additional statistically significant reduction in pain score in the IAB group at hour 4. There were no differences in narcotic consumption. Intraoperative local anesthetic and regional ACB each provides adequate pain control following knee arthroscopy, and intraoperative local anesthetic may provide enhanced pain control for up to 4 hours postoperatively. LEVEL OF EVIDENCE: : Level 1 evidence, randomized control trial.

BACKGROUND: Body mass index (BMI) is criticized for being unjust and biased in relatively healthy racial and ethnic groups. Therefore, the current analysis examines if BMI predicts body composition, specifically adiposity, in a racially and ethnically diverse acutely ill patient population. METHODS: Patients admitted with SARS-CoV-2 having an evaluable diagnostic chest, abdomen, and/or pelvic computed tomography (CT) study (within 5 days of admission) were included in this retrospective cohort. Cross-sectional areas (centimeters squared) of the subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), and intramuscular adipose tissue (IMAT) were quantified. Total adipose tissue (TAT) was calculated as sum of these areas. Admission height and weight were applied to calculate BMI, and self-reported race and ethnicity were used for classification. General linear regression models were conducted to estimate correlations and assess differences between groups. RESULTS: On average, patients (n = 134) were aged 58.2 (SD = 19.1) years, 60% male, and racially and ethnically diverse (33% non-Hispanic White [NHW], 33% non-Hispanic Black [NHB], 34% Hispanic). Correlations between BMI and SAT and BMI and TAT were strongest revealing estimates of 0.707 (0.585, 0.829) and 0.633 (0.534, 0.792), respectively. When examining the various adiposity compartments across race and ethnicity, correlations were similar and significant differences were not detected for TAT with SAT, VAT, or IMAT (all P ≥ 0.05). CONCLUSIONS: These findings support the routine use of applying BMI as a proxy measure of total adiposity for acutely ill patients identifying as NHW, NHB, and Hispanic. Our results inform the validity and utility of this tool in clinical nutrition practice.
RESUMO
Patients are sometimes mislabeled as having an immune-mediated antibiotic allergy in their medical records. Therefore, the aim of this study was to investigate the prevalence of subjects with non-immune mediated reactions to antibiotics using a standardized questionnaire. Subjects aged 18 years and older with a documented antibiotic allergy were identified and recruited from 2 outpatient clinics in the greater Chicago area. Subjects completed a standardized questionnaire during a single visit regarding their previous adverse reaction to an antibiotic. For subjects with multiple documented antibiotic allergies, 1 questionnaire was filled out for each antibiotic allergy. Investigators subsequently evaluated the questionnaire responses to determine whether the adverse reaction was a true immune-mediated allergic reaction or an adverse drug reaction. A total of 98 subjects were recruited with completion of 159 questionnaires. Eighteen subjects (18.37%, 95% CI: 10.7%, 26.3%) had antibiotic allergy labels with no corresponding immune-mediated reaction history. There were 35 allergy labels (22.0%, 95% CI: 14.7%, 29.4%) that were unlikely to be immune-mediated. Antibiotics with the highest percentage of clinical histories that were unlikely to be immune-mediated were macrolides (8 of 11 subjects), nitrofurantoin (1 of 2 subjects), and amoxicillin/clavulanate (2 of 8 subjects). The most common antibiotic allergy labels were penicillin (43 of 159 subjects), sulfonamides (25 of 159 subjects), and fluoroquinolones (21 of 159 subjects). Identification of adverse reactions to antibiotics that are unlikely to be immune-mediated can be accomplished using a standardized questionnaire in the outpatient setting. Improved identification of low-risk antibiotic allergy labels can guide de-labeling initiatives to improve antibiotic prescribing.
