Predictors of Engagement in Postpartum Weight Self-management Behaviours in the First 12 Weeks After Birth
Aim
To explore factors that influence postpartum weight self-management behaviours. Transitions Theory and the Integrated Theory of Health Behaviour Change guided selection of variables. Transition conditions, level of patient activation and social facilitation were examined for association with postpartum weight self-management behaviours. Background
Retention of pregnancy weight increases risk of overweight and obesity later in life. Little is known about what women do to self-manage return to pre-pregnant weight and how providers can influence their behaviours. Design
Prospective, longitudinal, correlational. Methods
Data collection occurred from March through October, 2013. One hundred and twenty-four women completed surveys during postpartum hospitalization; telephone interviews were completed by 91 women at 6 weeks and 66 women at 12 weeks. Standard and hierarchical multiple regression methods were used for analyses. Results
Transition difficulty was negatively associated with patient activation and immediate postbirth patient activation was positively associated with eating behaviours at 6 weeks, eating behaviours at 12 weeks and physical activity at 12 weeks. Social support and social influence were not significant predictors in the regression models. Conclusion
Patients experiencing a difficult postpartum transition have lower activation levels; those less activated are less probably to engage in weight self-management behaviours in the 12 weeks following their baby\u27s birth. Patient activation level should be considered in tailoring promotion of healthy postpartum weight management

Demographic, clinical, and treatment characteristics of the juvenile primary fibromyalgia syndrome cohort enrolled in the Childhood Arthritis and Rheumatology Research Alliance Legacy Registry.
BackgroundTo describe the demographic, clinical, and treatment characteristics of youth diagnosed with juvenile primary fibromyalgia syndrome (JPFS) who are seen in pediatric rheumatology clinics.MethodsInformation on demographics, symptoms, functioning, and treatments recommended and tried were obtained on patients with JPFS as part of a multi-site patient registry (the Childhood Arthritis and Rheumatology Research Alliance Legacy Registry). Data were summarized using descriptive statistics. In a subset of patients completing registry follow-up visits, changes in symptoms, pain, and functioning were evaluated using growth modeling.ResultsOf the 201 patients with JPFS enrolled in the registry, most were Caucasian/White (85%), non-Hispanic (83%), and female (84%). Ages ranged from 9 to 20 years (M = 15.4 + 2.2). The most common symptoms reported were widespread musculoskeletal pain (91%), fatigue (84%), disordered sleep (82%), and headaches (68%). Pain intensity was rated as moderate to severe (M = 6.3 + 2.4/10). Scores on measures of functioning indicated mild to moderate impairment, with males observed to report significantly greater impairments. For the 37% of the initial cohort having follow-up data available, indicators of function and well-being were found to either worsen over time or remain relatively unchanged.ConclusionsThe symptoms of JPFS remained persistent and disabling for many patients treated by pediatric rheumatologists. Further study appears warranted to elucidate gender differences in the impact of JPFS symptoms. Work also is needed to identify accessible and effective outpatient treatment options for JPFS that can be routinely recommended or implemented by pediatric rheumatology providers
Weight-Management Information Needs of Postpartum Women
Purpose: To describe the weight loss information-seeking behaviors of postpartum women. Study Design and Methods: The study is part of a larger longitudinal descriptive study of factors associated with women\u27s self-management of their gestational weight loss after birth. Participants answered questions about weight loss information they planned to access, had received, wished they had received, and desired sources of information. A total of 250 women were enrolled during the postpartum hospital stay; 179 completed a 4-month follow-up. Results: A large portion of the sample (53.3% of normal weight women, 79% of overweight women, and 81.4% obese women) identified plans to seek weight loss information, yet nearly 85% received no information from healthcare providers by 4 months postpartum. The most frequently reported desired information topics fell under the category of specific strategies to lose weight. The majority of women in the sample had access to online health information from home, work, or a library; however, more White women had this access than did Black or Hispanic women. Clinical Implications: Postpartum hospital nurses are in a unique position to provide high-quality information with strategies for managing postpartum loss of gestational weight. Provision of high-quality online or print information can provide the foundation for successful weight-management support for prevention of gestational weight retention and long-term maintenance of a healthy weight

VCBART: Bayesian trees for varying coefficients
Many studies have reported associations between later-life cognition and
socioeconomic position in childhood, young adulthood, and mid-life. However,
the vast majority of these studies are unable to quantify how these
associations vary over time and with respect to several demographic factors.
Varying coefficient (VC) models, which treat the covariate effects in a linear
model as nonparametric functions of additional effect modifiers, offer an
appealing way to overcome these limitations. Unfortunately, state-of-the-art VC
modeling methods require computationally prohibitive parameter tuning or make
restrictive assumptions about the functional form of the covariate effects.
In response, we propose VCBART, which estimates the covariate effects in a VC
model using Bayesian Additive Regression Trees. With simple default
hyperparameter settings, VCBART outperforms existing methods in terms of
covariate effect estimation and prediction. Using VCBART, we predict the
cognitive trajectories of 4,167 subjects from the Health and Retirement Study
using multiple measures of socioeconomic position and physical health. We find
that socioeconomic position in childhood and young adulthood have small effects
that do not vary with age. In contrast, the effects of measures of mid-life
physical health tend to vary with respect to age, race, and marital status. An
R package implementing VC-BART is available at

The Infrared Imaging Spectrograph (IRIS) for TMT: Data Reduction System
IRIS (InfraRed Imaging Spectrograph) is the diffraction-limited first light
instrument for the Thirty Meter Telescope (TMT) that consists of a
near-infrared (0.84 to 2.4 m) imager and integral field spectrograph
(IFS). The IFS makes use of a lenslet array and slicer for spatial sampling,
which will be able to operate in 100's of different modes, including a
combination of four plate scales from 4 milliarcseconds (mas) to 50 mas with a
large range of filters and gratings. The imager will have a field of view of
3434 arcsec with a plate scale of 4 mas with many selectable
filters. We present the preliminary design of the data reduction system (DRS)
for IRIS that need to address all of these observing modes. Reduction of IRIS
data will have unique challenges since it will provide real-time reduction and
analysis of the imaging and spectroscopic data during observational sequences,
as well as advanced post-processing algorithms. The DRS will support three
basic modes of operation of IRIS; reducing data from the imager, the lenslet
IFS, and slicer IFS. The DRS will be written in Python, making use of
open-source astronomical packages available. In addition to real-time data
reduction, the DRS will utilize real-time visualization tools, providing
astronomers with up-to-date evaluation of the target acquisition and data
quality. The quicklook suite will include visualization tools for 1D, 2D, and
3D raw and reduced images. We discuss the overall requirements of the DRS and
visualization tools, as well as necessary calibration data to achieve optimal
data quality in order to exploit science cases across all cosmic distance
scales.Comment: 13 pages, 2 figures, 6 tables, Proceeding 9913-165 of the SPIE

Absence of an association of human polyomavirus and papillomavirus infection with lung cancer in China: a nested case–control study
Abstract Background Studies of human polyomavirus (HPyV) infection and lung cancer are limited and those regarding the association of human papillomavirus (HPV) infection and lung cancer have produced inconsistent results. Methods We conducted a nested case–control study to assess the association between incident lung cancer of various histologies and evidence of prior infection with HPyVs and HPVs. We selected serum from 183 cases and 217 frequency matched controls from the Yunnan Tin Miner’s Cohort study, which was designed to identify biomarkers for early detection of lung cancer. Using multiplex liquid bead microarray (LBMA) antibody assays, we tested for antibodies to the VP1 structural protein and small T antigen (ST-Ag) of Merkel cell, KI, and WU HPyVs. We also tested for antibodies against HPV L1 structural proteins (high-risk types 16, 18, 31, 33, 52, and 58 and low-risk types 6 and 11) and E6 and E7 oncoproteins (high risk types 16 and 18). Measures of antibody reactivity were log transformed and analyzed using logistic regression. Results We found no association between KIV, WUV, and MCV antibody levels and incident lung cancer (P-corrected for multiple comparisons >0.10 for all trend tests). We also found no association with HPV-16, 18, 31, 33, 52, and 58 seropositivity (P-corrected for multiple comparisons >0.05 for all). Conclusions Future studies of infectious etiologies of lung cancer should look beyond HPyVs and HPVs as candidate infectious agents
Safety of celecoxib and nonselective nonsteroidal anti-inflammatory drugs in juvenile idiopathic arthritis: results of the phase 4 registry
Background
This study aimed to assess long-term safety and developmental data on juvenile idiopathic arthritis (JIA) patients treated in routine clinical practice with celecoxib or nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs). Methods
Children aged ≥2 to \u3c18 years with rheumatoid-factor–positive or –negative polyarthritis, persistent or extended oligoarthritis, or systemic arthritis were enrolled into this prospective, observational, multicenter standard-of-care registry. Eligible patients were newly or recently prescribed (≤6 months) an nsNSAID or celecoxib. Enrolled patients were followed to the end of the study, whether they remained on the original NSAID, switched, or discontinued therapy altogether. All adverse events (AEs) regardless of severity were captured in the database. Results
A total of 274 patients (nsNSAID, n = 219; celecoxib, n = 55) were observed for 410 patient-years of observation. Naproxen, meloxicam, and nabumetone were the most frequently used nsNSAIDs. At baseline, the celecoxib group was older, had a numerically longer median time since diagnosis, and a numerically higher proportion of patients with a history of gastrointestinal-related NSAID intolerance. AEs reported were those frequently observed with NSAID treatment and were similar across groups (nsNSAIDs: 52.0%; celecoxib: 52.9%). Twelve unique patients experienced a total of 18 serious AEs; the most frequent were infections, and none was attributed to NSAID use. Conclusions
The safety profile of celecoxib and nsNSAIDs appears similar overall. The results from this registry, ongoing pharmacovigilance, and the phase 3 trial that led to the approval of celecoxib for children with JIA provide evidence that the benefit-risk for celecoxib treatment in JIA remains positive
