81. Assessing the impact of quality improvement measures on catheter related blood stream infections and catheter salvage: Experience from a national intestinal failure unit. (PubMed)

Assessing the impact of quality improvement measures on catheter related blood stream infections and catheter salvage: Experience from a national intestinal failure unit. Prevention of catheter related blood stream infections (CRBSI) and salvage of infected central venous catheters (CVC) are vital to maintaining long term venous access in patients needing home parenteral nutrition (HPN). It remains unclear as to whether patients are best trained for catheter care at home or in hospital (...) or whether CRBSIs are lower if the patient self-cares for the CVC. Furthermore, there is minimal data on the longer term outcome following salvage of infected catheter and limited consensus on agreed protocols for catheter salvage.We conducted a retrospective 5-year evaluation of CRBSI occurrence and CVC salvage outcomes in adult patients requiring HPN managed at a national UK Intestinal Failure Unit from 2012 to 2016. Prior to 2012, patients were primarily trained to administer PN in hospital

82. Association Between Discrimination and Objective and Subjective Sleep Measures in the Midlife in the United States Study Adult Sample. (PubMed)

Association Between Discrimination and Objective and Subjective Sleep Measures in the Midlife in the United States Study Adult Sample. Evidence suggests that sleep quality is worse in nonwhite minorities compared with whites. Poor sleep is associated with higher levels of perceived interpersonal discrimination, which is consistently reported among minorities. However, the literature is limited in exploring discrimination with both objective and subjective sleep outcomes in the same sample. We (...) examined the relationship between discrimination and markers of subjective and objective sleep in a racially diverse sample.The analytic sample included 441 participants of the Midlife in the United States II (MIDUS) study (M [SD] age, 46.6 [1.03]; female, 57.9%; male, 42.1%; nonwhite, 31.7%). Complete data were available for 361 participants. Sleep measures included the Pittsburgh Sleep Quality Index, sleep latency, wake after sleep onset, and sleep efficiency derived from 7-day actigraphy

83. Comparison of Measures of Adherence to HIV Preexposure Prophylaxis among Adolescent and Young Men Who Have Sex with Men in the United States. (PubMed)

Comparison of Measures of Adherence to HIV Preexposure Prophylaxis among Adolescent and Young Men Who Have Sex with Men in the United States. Young men-who-have-sex-with-men (MSM) are disproportionately impacted by human immunodeficiency virus (HIV). Preexposure prophylaxis (PrEP) could reduce HIV acquisition among youth, but suboptimal adherence threatens effectiveness. Optimal metrics of PrEP adherence among adolescents have remain undefined.The Adolescent Trials Network 110/113 studies (...) provided daily oral PrEP with tenofovir (TFV) disoproxil fumarate/emtricitabine over 48 weeks to a diverse population of MSM (aged 15-22 years). Self-reported adherence was assessed and PrEP drug concentrations measured from hair and dried blood spot (DBS) samples; 23% of participants received Wisepill electronic monitoring devices. The average number of PrEP doses per week taken was estimated, and concordance between measures assessed.Among 243 participants, hair samples were collected at 1186/1238

Zinc Protoporphyrin-to-Heme Ratio and Ferritin as Measures of Iron Sufficiency in the Neonatal Intensive Care Unit. To evaluate ferritin and zinc protoporphyrin-to-heme (ZnPP/H) ratios as biomarkers of iron status in neonates, determine how specific clinical events affected these measures, and assess how iron status changed during hospitalization.We performed a retrospective study of all infants with paired ferritin and ZnPP/H measurements between October 2014 and May 2016. Concordance (...) of these measurements, effects of sepsis, red blood cell transfusion, erythropoietin treatment, and iron supplementation were assessed. Iron status was measured over time.A total of 228 patients (mean birth weight 1.3 kg, median gestational age 29 weeks) were evaluated. Mean log ZnPP/H values in infants with and without sepsis were not significantly different (4.98 µmol/mol vs 4.97 µmol/mol, adjusted P = .103), whereas log-transformed ferritin values increased significantly during infection (5.23 ng/mL vs 4.04 ng

85. Measurement error in intensive care unit length of stay estimates due to patient flow. (PubMed)

Measurement error in intensive care unit length of stay estimates due to patient flow. Clinical endpoints measured in terms of duration, such as intensive care unit (ICU) length of stay (LOS), are widely used in randomized clinical trials (RCTs) and observational research. In analyses of patient-level data from a recent RCT, in which ICU LOS was the primary endpoint, and in administrative data, we showed that additional ICU time is often accrued by patients after they are deemed ready (...) for discharge. This "immutable" time (which cannot plausibly be altered by interventions under study) varies by day, week, and year, adding on average one-third of a day to total LOS. We then used statistical simulations, informed by the administrative data and RCT, to assess the impact of immutable time on the measurement and statistical comparison of patients' ICU LOS. These simulations demonstrated that immutable time combines with clinically necessary ICU time (neither of which is likely to be normally

90. Measurement of Distal Ulnar Hounsfield Units Accurately Predicts Bone Mineral Density of the Forearm. (PubMed)

Measurement of Distal Ulnar Hounsfield Units Accurately Predicts Bone Mineral Density of the Forearm. Hounsfield unit (HU) measurement obtained from computed tomography (CT) scans of the wrist is a potential new screening method for low bone mineral density (BMD). We hypothesized that HU measurements of the ulnar head obtained from CT scans would correlate with BMD assessed with dual x-ray absorptiometry (DXA) scans of the forearm.Patients with both upper-extremity CT and DXA scans performed (...) at a single institution were included in the study. Hounsfield units were manually measured in the distal part of the ulna by 1 author blinded to the DXA results. Average values were then compared with forearm BMD values as determined with a DXA scan.Seventy-seven CT scans of 74 patients were included. Average HU values were significantly lower in the osteoporotic and osteopenic groups in comparison with the normal BMD group. The upper limit of the 95% confidence interval for osteopenic patients was 145.9

97. Behavioral Dynamics in Swimming: The Appropriate Use of Inertial Measurement Units (PubMed)

Behavioral Dynamics in Swimming: The Appropriate Use of Inertial Measurement Units Motor control in swimming can be analyzed using low- and high-order parameters of behavior. Low-order parameters generally refer to the superficial aspects of movement (i.e., position, velocity, acceleration), whereas high-order parameters capture the dynamics of movement coordination. To assess human aquatic behavior, both types have usually been investigated with multi-camera systems, as they offer high three (...) -dimensional spatial accuracy. Research in ecological dynamics has shown that movement system variability can be viewed as a functional property of skilled performers, helping them adapt their movements to the surrounding constraints. Yet to determine the variability of swimming behavior, a large number of stroke cycles (i.e., inter-cyclic variability) has to be analyzed, which is impossible with camera-based systems as they simply record behaviors over restricted volumes of water.

99. Measuring Maternal Behaviors in the Neonatal Intensive Care Unit (PubMed)

Measuring Maternal Behaviors in the Neonatal Intensive Care Unit One of the most important considerations in designing clinical infant research studies is the selection of reliable and valid measurement procedures. Few measures of caregiver-child interactions have been studied with newborns, particularly premature infants. The main objective of this study was to examine psychometric properties of the NICHD Mother-Child Interaction Qualitative Ratings in a sample of premature infants (...) and their mothers to evaluate its use in the Neonatal Intensive Care Unit (NICU). Mother-baby dyads (N=24) were videotaped in a 10-minute interaction in the NICU. Nine raters independently assessed dyadic interactions using the NICHD Mother-Child Interaction Qualitative Ratings in a fully-crossed research design. Rater reliability was strong for mother and infant ratings, (.76 to .94). Scores yielded normal distributions for maternal sensitivity, positive regard, and flatness of affect and skewed distributions

A 7.4 ps FPGA-Based TDC with a 1024-Unit Measurement Matrix In this paper, a high-resolution time-to-digital converter (TDC) based on a field programmable gate array (FPGA) device is proposed and tested. During the implementation, a new architecture of TDC is proposed which consists of a measurement matrix with 1024 units. The utilization of routing resources as the delay elements distinguishes the proposed design from other existing designs, which contributes most to the device insensitivity (...) to variations of temperature and voltage. Experimental results suggest that the measurement resolution is 7.4 ps, and the INL (integral nonlinearity) and DNL (differential nonlinearity) are 11.6 ps and 5.5 ps, which indicates that the proposed TDC offers high performance among the available TDCs. Benefitting from the FPGA platform, the proposed TDC has superiorities in easy implementation, low cost, and short development time.
