RESUMEN
BACKGROUND: Reflection spectroscopy, utilized by the Veggie Meter, is a less-expensive, noninvasive method to quantify skin carotenoids and is a valid approximation of fruit and vegetable (FV) intake. However, it is unknown to what degree Veggie Meter-assessed skin carotenoid score change is responsive to changes in carotenoid intake. OBJECTIVES: This study aimed to evaluate Veggie Meter-assessed skin carotenoid score response in a 6-wk randomized controlled trial of a carotenoid-containing juice to determine whether the Veggie Meter can be used to detect nutritionally relevant changes in carotenoid intake; and to compare skin and plasma carotenoid responses with the 6-wk trial. METHODS: In this 6-wk trial, participants (n = 162) who self-identified as one of 4 US racial/ethnic groups (25% Black, 25% Asian, 27% non-Hispanic White, 23% Hispanic) were randomized to a control group, receiving negligible carotenoids (177 mL apple juice/d), moderate-dose group, receiving 4 mg total carotenoids/d (177 mL orange-carrot juice/d), or high-dose group, receiving 8 mg total carotenoids/d (355 mL orange-carrot juice/d). Skin carotenoid score and plasma total carotenoid concentrations (α-carotene, ß-carotene, ß-cryptoxanthin, lycopene, lutein, zeaxanthin) were assessed at baseline, 3 wk, and 6 wk (n = 158 completed the trial). Repeated measures linear models were used to examine skin and plasma carotenoids over time and between groups. RESULTS: At 6 wk, participants in the high-dose and moderate-dose groups had significantly higher mean skin carotenoid scores [414.0 (SD = 100.6) and 369.7 (SD = 100.3), respectively] compared with those in the control group [305.2 (100.5)]. In the high-dose group, there was a 42% change in skin carotenoids from baseline (mean = 290.4) to a 6-wk follow-up (increase of 123, 123/290 = 42.4%). There was a 61% change in the plasma carotenoids in the high-dose group. CONCLUSIONS: The Veggie Meter is sensitive to increases in daily carotenoid intake in diverse racial/ethnic groups over 6 wk.

BACKGROUND: The present study used the American College of Surgeons National Surgical Quality Improvement Program dataset to identify the predictors of 30-day mortality for nonagenarians undergoing endovascular aortic aneurysm repair (EVAR) or open surgical repair (OSR). METHODS: Patients aged >90 years who had undergone abdominal aortic aneurysm repair from 2005 to 2017 were identified using procedure codes. Those with operative times <15 minutes were excluded. The demographics, preoperative comorbidities, and postoperative complications of those who had died by 30 days were compared with those of the patients alive at 30 days. RESULTS: A total of 1356 nonagenarians met the criteria: 1229 (90.6%) had undergone EVAR and 127 (9.4%) had undergone OSR. The overall 30-day mortality was 10.4%. The patients who had died within 30 days were significantly more likely to have undergone OSR than EVAR (40.9% vs 7.2%; P < .001). They also had a greater incidence of dependent functional status (22.0% for those who had died vs 8.1% for those alive at 30 days; P < .001), American Society of Anesthesiology (ASA) classification of ≥4 (81.2% vs 18.8%; P < .001), perioperative blood transfusion (59.6% vs 20.3%; P < .001), postoperative pneumonia (12.1% vs 2.9%; P = .001), mechanical ventilation >48 hours (22.7% vs 2.6%; P < .001), and acute renal failure (12.1% vs 0.5%; P < .001). The EVAR group had a 30-day mortality rate of 2.6% in 1008 elective cases and 28.6% in 221 emergent cases. The OSR group had a 30-day mortality rate of 19.1% in 47 elective cases and 53.7% in 80 emergent cases. In the EVAR cohort, the 30-day mortality group had had a significantly greater incidence of dependent functional status (17% for those who had died vs 8% for those alive at 30 days; P = .004), ASA classification of ≥4 (76.4% vs 40.3%; P < .001), perioperative blood transfusion (57% vs 19%; P < .001), emergency surgery (71% vs 14%; P < .001), and longer operative times (150 vs 128 minutes; P = .001). CONCLUSIONS: Nonagenarians had an incrementally increased, but acceptable, risk of 30-day mortality with EVAR in elective and emergent cases compared with that reported for octogenarians and cohorts of patients not selected for age. We found greater mortality for patients with dependent status, a higher ASA classification, emergent repair, and OSR. These preoperative risk factors could help identify the best surgical candidates. Given these results, consideration for EVAR or OSR might be reasonable for highly selected patients, especially for elective patients with a larger abdominal aortic aneurysm diameter for whom the risk of rupture is higher.

Occupational health nurses play a key role in evaluating innovative technologies that can aid in providing safe and rapid care and reduce lost work time. A nurse-led employee health clinic participated in a validation study of a novel pathogen detection technique developed by GeneCapture, Inc. Their proposed portable urinary tract infection (UTI) in vitro diagnostic test was challenged with discarded, deidentified urine samples from patients presenting with typical UTI symptoms collected at two university clinics and two multiphysician practices. GeneCapture's panel for this study was designed to rapidly identify the genetic signature of seven organisms: gram-negative Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa; gram-positive Enterococcus faecalis and Staphylococcus aureus; and fungal Candida species. The results from 40 clinical samples were in 95% agreement (90% specificity, 100% sensitivity) with traditional urine culture results from routine analysis. This successful occupational health nursing collaboration and validation study shows promise for point-of-care diagnoses and earlier treatment for workers with UTIs.

This study focused on gaining a better understanding of the neuropsychological abilities of preschool-aged children who show elevated levels of hyperactivity and oppositional-defiance. It examined the performance of children aged 48 to 67 months on tests of attention/executive function, language, memory, and sensorimotor abilities, as measured by the NEPSY and Conners' K-CPT. Two hundred thirty-seven children were divided into four subgroups based on mothers' report of behavior using rating scales and a diagnostic interview: hyperactive only (HYP), oppositional-defiant only (OD), hyperactive and oppositional-defiant (HYP/OD), and nonproblem. Children in the HYP/OD group scored significantly worse than nonproblem children on four of nine subtests on the NEPSY, including one test of executive function, one test of language comprehension, and both tests of short-term verbal memory. However, only the test of executive function (Statue) showed significant predictive power, and, while specificity of this subtest was good, sensitivity was poor. On the K-CPT, a continuous performance test, children in both the HYP and HYP/OD groups performed worse than children in the OD and nonproblem groups. When the NEPSY Statue subtest and the K-CPT were used together, overall predictive power was .74. Results suggest that neuropsychological deficits can be observed among preschool children with hyperactivity, particularly when comorbid oppositional-defiance is present; however, moderate predictive power suggests that these tests should be used in conjunction with other methods of assessment.

OBJECTIVES: To determine the risk factors in diabetic patients that are associated with increased postcolectomy mortality and anastomotic leak. DESIGN: A prospectively acquired statewide database of patients who underwent colectomy was reviewed. Primary risk factors were diabetes mellitus, hyperglycemia (glucose level ≥ 140 mg/dL), steroid use, and emergency surgery. Categorical analysis, univariate logistic regression, and multivariate regression were used to evaluate the effects of these risk factors on outcomes. SETTING: Participating hospitals within the Michigan Surgical Quality Collaborative. PATIENTS: Database review of patients from hospitals within the Michigan Surgical Quality Collaborative. MAIN OUTCOME MEASURES: Anastomotic leak and 30- day mortality rate. RESULTS: Of 5123 patients, 153 (3.0%) had leaks and 153 (3.0%) died. Preoperative hyperglycemia occurred in 15.6% of patients, only 54% of whom were known to have diabetes. Multivariate analysis showed that the risk of leak for patients with and without diabetes increased only by preoperative steroid use (P<.05). Mortality among diabetic patients was associated with emergency surgery (P<.01) and anastomotic leak (P<.05); it was not associated with hyperglycemia. Mortality among nondiabetic patients was associated with hyperglycemia (P<.005). The presence of an anastomotic leak was associated with increased mortality among diabetic patients (26.3% vs 4.5%; P<.001) compared with nondiabetic patients (6.0% vs 2.5%; P<.05). CONCLUSIONS: The presence of diabetes did not have an effect on the presence of an anastomotic leak, but diabetic patients who had a leak had more than a 4-fold higher mortality compared with nondiabetic patients. Preoperative steroid use led to increased rates of anastomotic leak in diabetic patients. Mortality was associated with hyperglycemia for nondiabetic patients only. Improved screening may identify high-risk patients who would benefit from perioperative intervention.

We developed and pilot tested a 2-session motivational interviewing intervention for substance use among 14- to 18-year-old medical patients. Recruitment and retention were more challenging than anticipated. A substantial number of completers reduced their use of substances and risk of driving after drinking during the 3-month follow-up period.

BACKGROUND: Adolescents should be screened for alcohol misuse as part of routine care. The objective of this study was to compare the criterion validity of the Alcohol Use Disorders Identification Test (AUDIT), the Problem Oriented Screening Instrument for Teenagers substance use/abuse scale (POSIT), and the CAGE and CRAFFT questions among adolescents. METHODS: Fourteen- to 18-year-old patients arriving for routine healthcare at a large, hospital-based adolescent clinic completed the four screens and the criterion standard Adolescent Diagnostic Interview, which yields DSM-IV diagnoses of alcohol abuse and dependence. Receiver operating characteristic (ROC) curves were plotted to determine optimal cut-points. Areas under the ROC curves of the four screens were compared, and sensitivities and specificities were calculated. RESULTS: Participants' past 12-month alcohol diagnostic classifications were as follows: no use (58.6%), nonproblem use (13.0%), problem use (20.8%), abuse (5.4%), and dependence (2.2%). Optimal cut-points associated with problem use or higher were 2 for AUDIT, 1 for POSIT, 1 for CAGE, and 1 for CRAFFT. ROC curve area of the CAGE was significantly lower compared with areas of all other screens. Sensitivities (95% confidence intervals) were AUDIT 0.88 (0.83-0.93), POSIT 0.84 (0.79-0.90), CAGE 0.37 (0.29-0.44), and CRAFFT 0.92 (0.88-0.96); specificities were AUDIT 0.81 (0.77-0.85), POSIT 0.89 (0.86-0.92), CAGE 0.96 (0.94-0.98), and CRAFFT 0.64 (0.59-0.69). CONCLUSIONS: The AUDIT, POSIT, and CRAFFT have acceptable sensitivity for identifying alcohol problems or disorders in this age group. The CAGE is not recommended for use among adolescents.

BACKGROUND: Adolescent substance abuse is a serious problem for which effective interventions are needed. To conduct trials of new therapies, investigators need reliable means of identifying potential participants and of measuring outcomes. The objective of this study was to determine the 1-week test-retest reliability of the CRAFFT screening test and of the timeline follow-back (TLFB) calendar method for measuring alcohol, cannabis, and other drug use. METHODS: Ninety-three 12- to 18-year-old patients presenting for routine medical care to three urban adolescent clinics were administered the CRAFFT screen in both lifetime and past-year versions and a 90-day TLFB. Both measures were completed on the day of the clinic visit and again 1 week later. We computed kappa coefficients and the intraclass correlation coefficient (ICC) for the CRAFFT and computed the ICC separately for TLFB self-reports of alcohol and cannabis. RESULTS: For the CRAFFT, kappa for individual items ranged from 0.31 to 0.86, and the ICC was 0.93 (95% confidence interval, 0.90-0.95). However, the total score of the lifetime CRAFFT at time 2 was significantly lower than at time 1; there was no difference in time 1 and time 2 total scores for the past-year version. The ICCs for past-90-days TLFB variables were as follows: drinking days, 0.92; drinks per occasion, 0.87; cannabis days, 0.83; and joints per occasion, 0.76. Past-30-day and past-60-day intervals compared favorably to past-90-day intervals. CONCLUSIONS: The CRAFFT screen is a reliable means of screening adolescents for substance abuse, although we recommend using the past-year version. The TLFB is a reliable method of quantifying adolescents' alcohol and cannabis use at intervals of 30, 60, or 90 days.
