Examining Heterogeneity of Outcomes in a Weight Gain Prevention Program for Young Adults. Obesity (Silver Spring) 2020; 28:521-528. [PMID: 32030910 PMCID: PMC7042032 DOI: 10.1002/oby.22720] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Accepted: 10/23/2019] [Indexed: 11/08/2022]
Abstract
OBJECTIVE This study aimed to characterize young adults who experienced significant weight gains (> 10%) over 3 years in a weight gain prevention program. METHODS Secondary data analysis from the Study of Novel Approaches to Weight Gain Prevention (SNAP), a randomized trial comparing two self-regulation interventions and a control arm in young adults (18-35 years; BMI 21-30.9 kg/m2 ), was used. Large Gainers (≥ 10% of their body weight; n = 48), Small Gainers (2.6%-9.9%; n = 149), and Weight Stable participants (± 2.5%; n = 143) were compared on dimensions affecting weight gain. RESULTS Differences in weight gain among the three groups were significant by year 1 and subsequently increased. Those who became Large Gainers were heavier at baseline and further below their highest weight, and they reported more weight cycling than Weight Stable, with Small Gainers intermediate. Neither study arm nor pregnancy explained weight change differences among the three groups. Large Gainers reported more depressive symptoms than Weight Stable at years 1 and 2. Large Gainers were less likely to weigh themselves at least weekly at 4 months, before differences in weight gain emerged, and at years 1 and 2. CONCLUSIONS Large Gainers (representing almost 10% of participants) could be identified early by greater weight issues at baseline and lower use of weight gain prevention strategies.

Abstract
The SPRINT (Systolic Blood Pressure Intervention Trial) demonstrated reduced cardiovascular outcomes. We evaluated diabetes mellitus incidence in this randomized trial that compared intensive blood pressure strategy (systolic blood pressure <120 mm Hg) versus standard strategy (<140 mm Hg). Participants were ≥50 years of age, with systolic 130 to 180 mm Hg and increased cardiovascular risk. Participants were excluded if they had diabetes mellitus, polycystic kidney disease, proteinuria >1 g/d, heart failure, dementia, or stroke. Postrandomization exclusions included participants missing blood glucose or ≥126 mg/dL (6.99 mmol/L) or on hypoglycemics. The outcome was incident diabetes mellitus: fasting blood glucose ≥126 mg/dL (6.99 mmol/L), diabetes mellitus self-report, or new use of hypoglycemics. The secondary outcome was impaired fasting glucose (100-125 mg/dL [5.55-6.94 mmol/L]) among those with normoglycemia (<100 mg/dL [5.55 mmol/L]). There were 9361 participants randomized and 981 excluded, yielding 4187 and 4193 participants assigned to intensive and standard strategies. There were 299 incident diabetes mellitus events (2.3% per year) for intensive and 251 events (1.9% per year) for standard, rates of 22.6 (20.2-25.3) versus 19.0 (16.8-21.5) events per 1000 person-years of treatment, respectively (adjusted hazard ratio, 1.19 [95% CI, 0.95-1.49]). Impaired fasting glucose rates were 26.4 (24.9-28.0) and 22.5 (21.1-24.1) per 100 person-years for intensive and standard strategies (adjusted hazard ratio, 1.17 [1.06-1.30]). Intensive treatment strategy was not associated with increased diabetes mellitus but was associated with more impaired fasting glucose. The risks and benefits of intensive blood pressure targets should be factored into individualized patient treatment goals. Clinical Trial Registration- URL: http://www.clinicaltrials.gov.

J Cardiothorac Vasc Anesth 2019; 34:632-639. [PMID: 31882380 DOI: 10.1053/j.jvca.2019.10.044] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 10/09/2019] [Accepted: 10/26/2019] [Indexed: 11/11/2022]
Abstract
OBJECTIVE The goal of the study was to investigate the role time of day plays in perioperative outcomes. The authors examined intraoperative transfusion rates throughout the day in adult cardiac surgery patients. They hypothesized that the rate of transfusion changes with later case start times in scheduled cardiac surgery. DESIGN Retrospective observational study. SETTING Single academic medical center. PARTICIPANTS Adults undergoing cardiac surgery involving cardiopulmonary bypass. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The primary outcome was a composite variable of transfusion. The association between the time of day and the rate of transfusion was explored with a multivariate logistic regression to fit the effect of starting time as a cubic spline. There were 1,421 cases that met inclusion criteria. There were 1,220 cases that were matched for modeling. The estimated probability of a patient receiving a transfusion changed significantly with later case start times in the multivariable model after adjusting for initial hemoglobin, age, sex, height, ideal body weight, diabetes, peripheral vascular disease, stroke, chronic kidney disease, chronic obstructive pulmonary disease, duration of cardiopulmonary bypass, aortic cross clamp time, attending surgeon, and attending anesthesiologist (p = 0.032, C-statistic = 0.807, n = 1220). The estimated probability of receiving an intraoperative red blood cell transfusion increased with later case start times in the multivariable model (p = 0.027, C-statistic = 0.902, n = 1220). There was no difference in the probability of transfusion for plasma, cryoprecipitate, or platelets. CONCLUSIONS The observed rate of intraoperative blood product transfusion changed with later case start times in a multivariable model of scheduled cardiac surgery.

Abstract
OBJECTIVES Globus pharyngeus (GP) is described as the subjective sensation of having a "lump" in the throat in the absence of correlating physical findings or dysphagia. Historically, despite the frequency of patient complaints, GP has been difficult to quantify with current outcome measures. This is in large part due to lack of a user-friendly, modernized, objective patient-reported outcome measure (PROM) of symptom severity. The aim of this study is to develop a modernized, practical, validated PROM for evaluating GP symptom severity. METHODS The Laryngopharyngeal Measure of Perceived Sensation (LUMP questionnaire) was created in three phases: 1) item generation by an expert panel involving two laryngologists and two speech language pathologists developed from common patient-reported GP symptoms, with patient confirmation; 2) line-item reduction based on internal consistency and reliability; 3) and instrument validity, which was assessed by administering the questionnaire to patients complaining of GP as well as patients without GP. RESULTS A 19-item questionnaire was developed from an expert panel, which was then administered to 110 patients, 100 of whom met inclusion criteria. After statistical analysis, less internally consistent or relevant questions were removed, leaving eight items with an internal consistency (Cronbach alpha) of 0.892. When administered to 54 patients with GP versus 31 normal patients, the mean score was found to be higher in those with GP versus normal patients (P value <0.0001). CONCLUSION Preliminary results suggest the eight-item LUMP questionnaire is a valuable PROM for evaluating GP symptom severity. LEVEL OF EVIDENCE NA Laryngoscope, 2019.

Abstract
BACKGROUND AND OBJECTIVES Resection of primary retroperitoneal sarcomas (RPS) has a high incidence of recurrence. This study aims to identify patterns of recurrence and its impact on overall survival. METHODS Adult patients with primary retroperitoneal soft tissue sarcomas who underwent resection in 2000-2016 at eight institutions of the US Sarcoma Collaborative were evaluated. RESULTS Four hundred and ninety-eight patients were analyzed, with 56.2% (280 of 498) having recurrences. There were 433 recurrences (1-8) in 280 patients with 126 (25.3%) being locoregional, 82 (16.5%) distant, and 72 (14.5%) both locoregional and distant. Multivariate analyses revealed the following: Patient age P = .0002), tumor grade (P = .02), local recurrence (P = .0003) and distant recurrence (P < .0001) were predictors of disease-specific survival. The 1-, 3-, and 5-year survival rate for patients who recurred vs not was 89.6% (standard error [SE] 1.9) vs 93.5% (1.8), 66.0% (3.2) vs 88.4% (2.6), and 51.8% (3.6) vs 83.9% (3.3), respectively, P < .0001. Median survival was 5.3 years for the recurrence vs 11.3+ years for the no recurrence group (P < .0001). Median survival from the time of recurrence was 2.5 years. CONCLUSIONS Recurrence after resection of RPS occurs in more than half of patients independently of resection status or perioperative chemotherapy and is equally distributed between locoregional and distant sites. Recurrence is primarily related to tumor biology and is associated with a significant decrease in overall survival.

Abstract
PURPOSE Adequate understanding of the goals and adverse effects of cancer treatment has important implications for patients' decision making, expectations, and mood. This study sought to identify the degree to which patients and clinicians agreed upon the goals and adverse effects of treatment (ie, concordance). METHODS Patients completed a demographic questionnaire, the National Comprehensive Cancer Network Distress Thermometer, the Medical Outcomes Study Social Support Survey, the Functional Assessment of Chronic Illness Therapy-Treatment Satisfaction-General questionnaire, the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being questionnaire, and a 13-item questionnaire about the goals and adverse effects of treatment. Providers completed a 12-item questionnaire. RESULTS One hundred patients (51 female) and 34 providers participated (questionnaire return rate mean difference, 5 days; SD, 16 days). Patient and provider dyads agreed 61% of the time regarding the intent of treatment. In cases of nonagreement, 36% of patients reported more optimistic therapy goals compared to providers. Patients and providers agreed 69% of the time regarding the patient's acknowledgement and understanding of adverse effects. Patients who reported an understanding of likely adverse effects endorsed significantly lower distress scores (mean, 2.5) than those who endorsed not understanding associated adverse effects (mean, 4.1; P = .008). CONCLUSION Timely data capturing of patient-provider dyadic ratings is feasible. A significant discrepancy exists between a substantial percentage of patients' and providers' views of the intent and adverse effects of treatment. Patients were almost always more optimistic about the intent of treatment. Higher rates of distress were noted in cases of discordance. Providers may benefit from conversational feedback from patients as well as other integrated feedback systems to inform them about patient understanding.

Abstract
OBJECTIVES Vancomycin weight-based dosing regimens often fail to achieve therapeutic trough serum concentration in children ≤12 years of age and rigorous studies evaluating efficacy and safety of body surface area (BSA)-based dosing regimens have not been performed. We compared vancomycin trough serum concentrations in pediatric patients receiving a weight- or BSA-based dosing regimen. METHODS This was a single-center, retrospective study evaluating pediatric patients, ages 1 to 12 years, who received vancomycin from September 2012 to October 2015. Patients received a minimum of 3 consecutive doses at the same scheduled interval within a dosing regimen prior to a measured vancomycin serum trough concentration. The primary outcome was percentage of initial vancomycin trough concentrations ≥10 mg/L. The secondary outcomes were percentage of supratherapeutic, therapeutic, and subtherapeutic vancomycin serum concentration for all patients, including a subset of overweight and obese patients, and number of nephrotoxic occurrences. RESULTS BSA-based dosing regimens resulted in 50% of the initial vancomycin trough concentrations ≥ 10 mg/L compared with 17% for the weight-based dosing regimens (p < 0.0001). No statistically significant differences were noted between the 2 dosing regimens for supratherapeutic, therapeutic, or subtherapeutic trough concentrations for all patients, and for the subset of overweight and obese patients. Nephrotoxic occurrences were noted in 7% of the weight-based dosing regimens compared with none in the BSA-based dosing regimens. CONCLUSIONS A BSA-based vancomycin dosing regimen resulted in significantly more initial vancomycin trough concentrations ≥10 mg/L and trended towards higher initial vancomycin trough concentrations without observable nephrotoxicity.

Abstract
PURPOSE African Americans who shed JC polyomavirus (JCV) in their urine have reduced rates of nondiabetic chronic kidney disease (CKD). We assessed the associations between urinary JCV and urine BK polyomavirus (BKV) with CKD in African Americans with diabetes mellitus. METHODS African Americans with diabetic kidney disease (DKD) and controls lacking nephropathy from the Family Investigation of Nephropathy and Diabetes Consortium (FIND) and African American-Diabetes Heart Study (AA-DHS) had urine tested for JCV and BKV using quantitative PCR. Of the 335 individuals tested, 148 had DKD and 187 were controls. RESULTS JCV viruria was detected more often in the controls than in the patients with DKD (FIND: 46.6% vs 32.2%; OR, 0.52; 95% CI, 0.29 to 0.93; P = 0.03; AA-DHS: 30.4% vs 26.2%; OR, 0.63; 95% CI, 0.27 to 1.48; P = 0.29). A joint analysis adjusted for age, sex, and study revealed that JC viruria was inversely associated with DKD (OR, 0.56; 95% CI, 0.35 to 0.91; P = 0.02). Statistically significant relationships between BKV and DKD were not observed. MAIN CONCLUSIONS The results from the present study extend the inverse association between urine JCV and nondiabetic nephropathy in African Americans to DKD. These results imply that common pathways likely involving the innate immune system mediate coincident chronic kidney injury and restriction of JCV replication. Future studies are needed to explore causative pathways and characterize whether the absence of JC viruria can serve as a biomarker for DKD in the African American population.

Abstract
Chest radiographs (CXRs) and laboratory testing have historically been performed as a part of low-risk melanoma (clinical stage 1/2) workup. This study evaluates the utility of routine CXRs and laboratory testing during the staging of clinical stage 1 and 2 melanoma patients. This study was approved by the Institutional Review Board at Wake Forest University. A database of sentinel lymph node biopsies performed for clinical stage 1 or 2 melanoma was used to identify early-stage melanoma patients. The medical records of patients with melanoma were reviewed and preoperative workup procedures were recorded. Four hundred sixty-three patients were reviewed. A total of 315 patients underwent a preoperative CXR, whereas 309 received some laboratory testing. After sentinel node biopsies, 168 patients had pathologic stage 1 disease, 103 stage 2, and 44 stage 3. None of the CXRs (0%) correctly identified metastatic melanoma. Suspicious locations on CXRs and laboratory testing did not lead to metastatic findings in any patient within a year. Metastatic melanoma was not found in any patient by screening with CXRs or laboratory testing during preoperative workup. We recommend not conducting CXRs or laboratory testing during workup for surgical melanoma patients because of charges and anxiety these tests can cause. CXRs, blood tests, and metabolic panels have historically been ordered for early melanoma patients, although debate remains on their efficacy. Surgical patient records were retrospectively reviewed for these tests and no benefit was found.

Abstract
OBJECTIVES To evaluate if obesity is associated with increased angiotensin II (Ang II) and decreased angiotensin-(1-7) or Ang-(1-7) in the circulation and urine among adolescents born prematurely. STUDY DESIGN In a cross-sectional analysis of 175 14-year-olds born preterm with very low birth weight, we quantified plasma and urinary Ang II and Ang-(1-7) and compared their levels between subjects with overweight/obesity (body mass index ≥85th percentile, n = 61) and those with body mass index <85th percentile (n = 114) using generalized linear models, adjusted for race and antenatal corticosteroid exposure. RESULTS Overweight/obesity was associated with higher systolic blood pressure and a greater proportion with high blood pressure. After adjustment for confounders, overweight/obesity was associated with an elevated ratio of plasma Ang II to Ang-(1-7) (β: 0.57, 95% CI 0.23-0.91) and higher Ang II (β: 0.21 pmol/L, 95% CI 0.03-0.39) but lower Ang-(1-7) (β: -0.37 pmol/L, 95% CI -0.7 to -0.04). Overweight/obesity was associated with a higher ratio of urinary Ang II to Ang-(1-7) (β: 0.21, 95% CI -0.02 to 0.44), an effect that approached statistical significance. CONCLUSIONS Among preterm-born adolescents, overweight/obesity was associated with increased Ang II but reduced Ang-(1-7) in the circulation and the kidney as well as higher blood pressure. Obesity may compound the increased risk of hypertension and cardiovascular disease in individuals born prematurely by further augmenting the prematurity-associated imbalance in the renin-angiotensin system.

Abstract
OBJECTIVE To evaluate the predictive nature of several clinicopathological variables by developing a nomogram predictive for lymph node-positive disease using the National Cancer Database cohort of patients with squamous cell carcinoma of the penis. METHODS Stepwise logistic regression was used to find the best-fit model; remaining clinical variables were used to create a nomogram to predict the probability of lymph node-positive disease. RESULTS On multivariate analysis, high pathological grade (3-4 vs 1: odds ratio [OR] 3.27, 95% confidence interval [CI] 1.70-6.29; 2 vs 1: OR 2.58, 95% CI 1.39-4.79 [P = 0.002]), lymphovascular invasion (OR 2.49, 95% CI 1.61-3.84 [P < 0.001]), and positive clinical lymph node status (N1 vs N0: OR 20.0, 95% CI 11.4-35.7; N2 vs N0: OR 27.8, 95% CI 14.1-55.6; N3 vs N0: OR 49.2, 95% CI 14.8-162.8 [P < 0.001]) were predictors of lymph node metastasis in penile cancer. The bootstrap-corrected concordance index of this nomogram was 0.880. CONCLUSION Using tumour grade, tumour lymphovascular invasion and clinical lymph node status, we developed a nomogram highly predictive of pathologial lymph node metastasis that, after further external validation, could be helpful in the surgical decision-making process.

Abstract
Surgical site infection (SSI) and incisional hernia are common complications after major pancreatectomy. We investigated the effects of negative pressure wound therapy (NPWT) on short- and long-term wound outcomes in patients undergoing pancreatectomy. A randomized controlled trial comparing the effect of NPWT with standard surgical dressing (SSD) on wounds was performed in 265 patients undergoing open gastrointestinal resections from 2012 to 2016. We performed a subset analysis of 73 patients who underwent pancreatectomy. Wound complications in the first 30 days and incisional hernia rates were assessed. There were 33 (45%) female patients in the study and the average BMI was 27.6. The pancreaticoduodectomy rate was 68 per cent, whereas 27 per cent of patients underwent distal or subtotal pancreatectomy, and 4 per cent total pancreatectomy. Incisional hernia rates were 32 per cent and 14 per cent between the SSD and NPWT groups, respectively (P = 0.067). In the SSD (n = 37) and NPWT (n = 36) cohorts, the superficial SSI, deep SSI, seroma, and dehiscence rates were 16 per cent and 14 per cent (P > 0.99), 5 per cent and 8 per cent (P = 0.67), 16 per cent and 11 per cent (P = 0.74), and 5 per cent and 3 per cent (P ≥ 0.99), respectively. After adjusting for pancreatic fistula and delayed gastric emptying, no statistically significant differences in the primary outcomes were observed. These findings were true irrespective of the type of resection performed. Short- and long-term wound complications were not improved with NPWT. We observed a trend toward decreased incisional hernia rates in patients treated with NPWT. Owing to the multifactorial nature of wound complications, it is yet to be determined which cohorts of pancreatectomy patients will benefit from NPWT.

Abstract
OBJECTIVE The objective was to determine the impact of the HEART Pathway on health care utilization and safety outcomes at 1 year in patients with acute chest pain. METHODS Adult emergency department (ED) patients with chest pain (N = 282) were randomized to the HEART Pathway or usual care. In the HEART Pathway arm, ED providers used the HEART score and troponin measures (0 and 3 hours) to risk stratify patients. Usual care was based on American College of Cardiology/American Heart Association guidelines. Major adverse cardiac events (MACE-cardiac death, myocardial infarction [MI], or coronary revascularization), objective testing (stress testing or coronary angiography), and cardiac hospitalizations and ED visits were assessed at 1 year. Randomization arm outcomes were compared using Fisher's exact tests. RESULTS A total of 282 patients were enrolled, with 141 randomized to each arm. MACE at 1 year occurred in 10.6% (30/282): 9.9% in the HEART Pathway arm (14/141; 10 MIs, four revascularizations without MI) versus 11.3% in usual care (16/141; one cardiac death, 13 MIs, two revascularizations without MI; p = 0.85). Among low-risk HEART Pathway patients, 0% (0/66) had MACE, with a negative predictive value (NPV) of 100% (95% confidence interval = 93%-100%). Objective testing through 1 year occurred in 63.1% (89/141) of HEART Pathway patients compared to 71.6% (101/141) in usual care (p = 0.16). Nonindex cardiac-related hospitalizations and ED visits occurred in 14.9% (21/141) and 21.3% (30/141) of patients in the HEART Pathway versus 10.6% (15/141) and 16.3% (23/141) in usual care (p = 0.37, p = 0.36). CONCLUSIONS The HEART Pathway had a 100% NPV for 1-year safety outcomes (MACE) without increasing downstream hospitalizations or ED visits. Reduction in 1-year objective testing was not significant.

Abstract
Surgical site infection (SSI) and incisional hernia are common complications after major pancreatectomy. We investigated the effects of negative pressure wound therapy (NPWT) on short-and long-term wound outcomes in patients undergoing pancreatectomy. A randomized controlled trial comparing the effect of NPWT with standard surgical dressing (SSD) on wounds was performed in 265 patients undergoing open gastrointestinal resections from 2012 to 2016. We performed a subset analysis of 73 patients who underwent pancreatectomy. Wound complications in the first 30 days and incisional hernia rates were assessed. There were 33 (45%) female patients in the study and the average BMI was 27.6. The pancreaticoduodectomy rate was 68 per cent, whereas 27 per cent of patients underwent distal or subtotal pancreatectomy, and 4 per cent total pancreatectomy. Incisional hernia rates were 32 per cent and 14 per cent between the SSD and NPWT groups, respectively (P = 0.067). In the SSD (n = 37) and NPWT (n = 36) cohorts, the superficial SSI, deep SSI, seroma, and dehiscence rates were 16 per cent and 14 per cent (P > 0.99), 5 per cent and 8 per cent (P = 0.67), 16 per cent and 11 per cent (P = 0.74), and 5 per cent and 3 per cent (P ≥ 0.99), respectively. After adjusting for pancreatic fistula and delayed gastric emptying, no statistically significant differences in the primary outcomes were observed. These findings were true irrespective of the type of resection performed. Short- and long-term wound complications were not improved with NPWT. We observed a trend toward decreased incisional hernia rates in patients treated with NPWT. Owing to the multifactorial nature of wound complications, it is yet to be determined which cohorts of pancreatectomy patients will benefit from NPWT.

Abstract
BACKGROUND Preterm birth increases the risk of hypertension and kidney disease. However, it is unclear when changes in blood pressure (BP) and renal function become apparent and what role obesity and sex play. We hypothesized adolescents born preterm have higher BP and worse kidney function compared to term in an obesity- and sex-dependent manner. METHODS Cross-sectional analysis of 14-year-olds born preterm with very low birth weight (n = 96) compared to term (n = 43). We used generalized linear models to estimate the associations among preterm birth and BP, estimated glomerular filtration rate (eGFR), and ln (x) urinary albumin-to-creatinine ratio (ACR), stratified by overweight/obesity (OWO, body mass index (BMI) ≥ 85th percentile) and sex. RESULTS Compared to term, preterm-born adolescents had higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) (adjusted β (aβ) 3.5 mmHg, 95% CI - 0.1 to 7.2 and 3.6 mmHg, 95% CI 0.1 to 7.0), lower eGFR (β - 8.2 mL/min/1.73 m2, 95% CI - 15.9 to - 0.4), and higher ACR (aβ 0.34, 95% CI - 0.04 to 0.72). OWO modified the preterm-term difference in DBP (BMI < 85th percentile aβ 5.0 mmHg, 95% CI 0.7 to 9.2 vs. OWO 0.2 mmHg, 95% CI - 5.3 to 5.6) and ACR (OWO aβ 0.72, 95% CI 0.15 to 1.29 vs. BMI < 85th percentile 0.17, 95% CI - 0.31 to 0.65). Sex modified the preterm-term ACR difference (female aβ 0.52, 95% CI 0.001 to 1.04 vs. male 0.18, 95% CI - 0.36 to 0.72). CONCLUSIONS Prematurity was associated with higher BP and reduced renal function that were detectable in adolescence. OWO and sex may modify the strength of these relationships.

Abstract
BACKGROUND Peripheral nerve blockade is used to provide analgesia for patients undergoing total knee arthroplasty. This study compared a single-injection adductor canal block (SACB) with adjuvants to continuous adductor canal blockade (CACB). The hypothesis was that the 2 groups would have equivalent analgesia at 30 hours after neural blockade. METHODS This was a double-blinded, randomized, controlled, equivalency trial. Sixty patients were randomized to either the SACB group (20 mL of 0.25% bupivacaine, 1.67 mcg/mL of clonidine, 2 mg of dexamethasone, 150 mcg of buprenorphine, and 2.5 mcg/mL of epinephrine) or the CACB group (20 mL 0.25% of bupivacaine injection with 2.5 mcg/mL of epinephrine followed by an 8 mL/h infusion of 0.125% bupivacaine continued through postoperative day 2). The primary outcome was movement pain scores at 30 hours using the numeric rating scale (NRS). The secondary outcomes included serial postoperative NRS pain scores (rest and movement every 6 hours), opioid consumption, time to first opioid administration, ability to straight leg raise, patient satisfaction, length of stay, and the incidence of nausea/vomiting. RESULTS An intention-to-treat analysis included 59 patients. The NRS pain scores with movement were equivalent at 30 hours (SACB 5.5 ± 2.8 vs CACB 5.7 ± 2.9 [mean NRS ± standard deviation]; mean difference 0.2 [-1.5 to 1.0 {90% confidence interval}]). All NRS pain scores were equivalent until 42 hours (rest) and 48 hours (rest and movement) with the CACB group having lower pain scores. Other secondary outcomes were not statistically different. CONCLUSION An SACB provides equivalent analgesia for up to 36 hours after block placement when compared with a CACB for patients undergoing total knee arthroplasty, though a CACB was favored at 42 hours and beyond.

Abstract
UNLABELLED The study showed that in African-American men with type 2 diabetes mellitus (T2D), vertebral volumetric bone mineral density (vBMD) predicts all-cause mortality, independent of other risk factors for death. INTRODUCTION Compared to European Americans, African Americans have lower rates of osteoporosis and higher rates of T2D. The relationships between BMD and fractures with mortality are unknown in this population. The aim of this study was to determine relationships between vertebral fractures and vertebral vBMD and mortality in African Americans with T2D. METHODS Associations between vertebral fractures and vBMD with all-cause mortality were examined in 675 participants with T2D (391 women and 284 men) in the African American-Diabetes Heart Study (AA-DHS). Lumbar and thoracic vBMD were measured using quantitative computed tomography (QCT). Vertebral fractures were assessed on sagittal CT images. Associations of vertebral fractures and vBMD with all-cause mortality were determined in sex-stratified analyses and in the full sample. Covariates in a minimally adjusted model included age, sex, BMI, smoking, and alcohol use; the full model was adjusted for those variables plus cardiovascular disease, hypertension, coronary artery calcified plaque, hormone replacement therapy (women), African ancestry proportion, and eGFR. RESULTS After mean 7.6 ± 1.8-year follow-up, 59 (15.1%) of women and 58 (20.4%) of men died. In men, vBMD was inversely associated with mortality in the fully adjusted model: lumbar hazard ratio (HR) per standard deviation (SD) = 0.70 (95% CI 0.52-0.95, p = 0.02) and thoracic HR per SD = 0.71 (95% CI 0.54-0.92, p = 0.01). Only trends toward association between vBMD and mortality were observed in the combined sample of men and women, as significant associations were absent in women. Vertebral fractures were not associated with mortality in either sex. CONCLUSIONS Lower vBMD was associated with increased all-cause mortality in African-American men with T2D, independent of other risk factors for mortality including subclinical atherosclerosis.

Abstract
An initial electrocardiogram (ECG) and serial troponin measurements are both independently and incrementally predictive of acute coronary syndrome in patients presenting with undifferentiated chest pain in the Emergency Department (ED). However, it is unclear if serial (ECGs) add significant to the contemporary diagnostic evaluation of this patient group. The ASAP CATH study was a single center, prospective study that enrolled patients presenting to an ED with undifferentiated chest pain. In addition to standard clinical evaluation, serial ECGs were performed at 90-minute intervals to evaluate whether serial changes suggestive of ischemia developed (Q waves, ST elevation or depression, or T-wave inversion). Total 365 subjects were enrolled from March 2014 to May 2015. Serial ECG changes developed in 6.6% (n = 24 of 365), the most common being the development of T-wave inversion (66.7%, n = 16 of 24). The sensitivity and positive predictive value of serial ECG changes were poor (<30%), with a less areas under the curve (0.55) compared with serial troponins alone (0.83). The addition of serial ECG changes to Thrombolysis In Myocardial Infarction risk scoring showed a decrease in the net reclassification index for major adverse cardiovascular events (-0.04, p <0.1) and was not significant for the prediction of major adverse cardiovascular events and/or acute coronary syndrome in 30 days (-0.003, p = 0.94). In conclusion, routine serial ECG evaluation for patients presenting with undifferentiated chest pain in the ED may not significantly improved diagnostic prognosis beyond current standard evaluation modalities.

Abstract
AIM Recent studies revealed a correlation between skeletal muscle mass index and density with longevity; these studies largely evaluated appendicular skeletal muscles in older Caucasians. This retrospective cohort study assessed the association between axial skeletal muscles size and density with survival in African Americans with type 2 diabetes mellitus. METHODS Psoas and paraspinous muscle mass index (cross sectional area/height2) and radiographic density (in Hounsfield Units) were measured using computed tomography in African American-Diabetes Heart Study participants, 314 women and 256 men, with median (25th, 75th quartile) age 55.0(48.0, 62.0) and 57.0(50.0, 64.0) years, respectively. Covariates in fully-adjusted model included age, sex, BMI, smoking, hormone replacement therapy (women), cardiovascular disease, hypertension, coronary artery calcified plaque mass, carotid artery calcified plaque mass, and African ancestry proportion. RESULTS After median of 7.1(5.9, 8.2) years follow-up, 30(9.6%) of women and 49(19.1%) of men were deceased. In fully-adjusted models, psoas muscle mass index and paraspinous muscle mass index were inversely associated with mortality in men (psoas muscle mass index, hazard ratio [HR] = 0.61, P = 0.004; paraspinous muscle mass index, HR = 0.64, P = 0.004), but not in women. Psoas and paraspinous muscle densities did not associate with all-cause mortality. A penalized Cox regression that involved all covariates and predictors associated with mortality showed that only paraspinous muscle mass index remained a significant predictor of mortality (HR = 0.65, P = 0.02). CONCLUSION Independent from established risk factors for mortality, higher psoas and paraspinous muscle index associate with reduced all-cause mortality in middle-aged African American men with type 2 diabetes mellitus.

Perineural dexamethasone successfully prolongs adductor canal block when assessed by objective pinprick sensory testing: A prospective, randomized, dose-dependent, placebo-controlled equivalency trial. J Clin Anesth 2018; 48:51-57.

Abstract
STUDY OBJECTIVE To determine whether perineural dexamethasone prolongs peripheral nerve blockade (PNB) when measured objectively; and to determine if a 1 mg and 4 mg dose provide equivalent PNB prolongation compared to PNB without dexamethasone. SETTING Multiple studies have reported that perineural dexamethasone added to local anesthetics (LA) can prolong PNB. However, these studies have relied on subjective end-points to quantify PNB duration. The optimal dose remains unknown. We hypothesized that 1 mg of perineural dexamethasone would be equivalent in prolonging an adductor canal block (ACB) when compared to 4 mg of dexamethasone, and that both doses would be superior to an ACB performed without dexamethasone. DESIGN This was a prospective, randomized, double-blind, placebo-controlled equivalency trial involving 85 patients undergoing a unicompartmental knee arthroplasty. INTERVENTIONS All patients received an ACB with 20 ml of 0.25% bupivacaine with 1:400,000 epinephrine. Twelve patients had 0 mg of dexamethasone (placebo) added to the LA mixture; 36 patients had 1 mg of dexamethasone in the LA; and 37 patients had 4 mg of dexamethasone in the LA. MEASUREMENTS The primary outcome was block duration determined by serial neurologic pinprick examinations. Secondary outcomes included time to first analgesic, serial pain scores, and cumulative opioid consumption. MAIN RESULTS The 1 mg (31.8 ± 10.5 h) and 4 mg (37.9 ± 10 h) groups were not equivalent, TOST [Mean difference (95% CI); 6.1 (-10.5, -2.3)]. Also, the 4 mg group was superior to the 1 mg group (p-value = 0.035), and the placebo group (29.7 ± 6.8 h, p-value = 0.011). There were no differences in opioid consumption or time to analgesic request; however, some pain scores were significantly lower in the dexamethasone groups when compared to placebo. CONCLUSION Dexamethasone 4 mg, but not 1 mg, prolonged the duration of an ACB when measured by serial neurologic pinprick exams. CLINICAL TRIAL REGISTRATION NCT02462148.

Abstract
The study evaluated the physical,mental, and functional outcomes following below-the-knee amputation (BKA) for management of chronic, debilitating lower extremity pain. The hypothesis was that patients who undergo a BKA to alleviate chronic pain achieve a greater level of function, experience decreased pain, and benefit from improved health-related quality of life. Patients who received a BKA attended an orthopaedic clinic and completed questionnaires examining their overall health, functional status, mental health, and pain. Thirty-seven patients were identified as eligible for study participation; 15 agreed to participate. Although most participants continued to experience pain in their residual limb after BKA, they reported their pain decreased to a manageable level. Participants experienced a statistically significant improvement in their perceived physical health. The authors believe a BKA for chronic pain is a reasonable treatment option for patients who continue to experience lower extremity pain after failed medical and surgical management of chronic pain.

Abstract
OBJECTIVE Cardiovascular and renal complications contribute to higher mortality in patients with diabetes. We assessed novel and conventional predictors of mortality in African American-Diabetes Heart Study (AA-DHS) participants. RESEARCH DESIGN AND METHODS Associations between mortality and subclinical atherosclerosis, urine albumin-to-creatinine ratio (UACR), estimated glomerular filtration rate (eGFR), plasma fibroblast growth factor 23 (FGF23) concentration, African ancestry proportion, and apolipoprotein L1 genotypes (APOL1) were assessed in 513 African Americans with type 2 diabetes; analyses were performed using Cox proportional hazards models. RESULTS At baseline, participants were 55.6% female with median (25th, 75th percentile) age 55 years (49.0, 62.0), diabetes duration 8 years (5.0, 13.0), glycosylated hemoglobin 60.7 mmol/mol (48.6, 76.0), eGFR 91.3 mL/min/1.73 m2 (76.4, 111.3), UACR 12.5 mg/mmol (4.2, 51.2), and coronary artery calcium 28.5 mg Ca2+ (1.0, 348.6); 11.5% had two APOL1 renal-risk variants. After 6.6-year follow-up (5.8, 7.5), 54 deaths were recorded. Higher levels of coronary artery calcified plaque, carotid artery calcified plaque, albuminuria, and FGF23 were associated with higher mortality after adjustment for age, sex, and African ancestry proportion. A penalized Cox regression that included all covariates and predictors associated with mortality identified male sex (hazard ratio [HR] 4.17 [95% CI 1.96-9.09]), higher FGF23 (HR 2.10 [95% CI 1.59-2.78]), and absence of APOL1 renal-risk genotypes (HR 0.07 [95% CI 0.01-0.69]) as the strongest predictors of mortality. CONCLUSIONS Accounting for conventional risk factors, higher FGF23 concentrations and APOL1 non-renal-risk genotypes associated with higher mortality in African Americans with diabetes. These data add to growing evidence supporting FGF23 association with mortality; mechanisms whereby these novel predictors impact survival remain to be determined.

Abstract
BackgroundExposure to antenatal corticosteroids (ANCS) is associated with adverse cardiometabolic outcomes in animal models; however, long-term outcomes in clinical studies are not well characterized. We hypothesized that exposure to ANCS would be associated with markers of increased cardiometabolic risk in adolescents born with very low birth weight (VLBW).MethodsIn an observational cohort of 186 14-year-old adolescents born with VLBW, we measured resting blood pressure (BP), BP response to cold, ambulatory BP, and anthropometrics; performed dual-energy X-ray absorptiometry; and analyzed blood samples for uric acid, cholesterol, glycated hemoglobin, and high-sensitivity C-reactive protein. Multivariate analyses were used to evaluate associations with ANCS, adjusting for race, sex, and maternal hypertensive pregnancy.ResultsThere were no ANCS group differences in BP measures or blood biomarkers. Compared with adolescents unexposed to ANCS, those exposed to ANCS were taller (exposed-unexposed mean difference 3.1 cm (95% confidence interval (CI) 0.7, 5.5)) and had decreased waist-to-height ratio (exposed-unexposed mean difference -0.03 (95% CI -0.058, -0.002)). Males exposed to ANCS had lower total cholesterol (exposed-unexposed mean difference -0.54 mmol/l (95%CI -0.83, -0.06)).ConclusionAmong adolescents born with VLBW, ANCS exposure was not associated with markers of increased cardiometabolic risk.
