Prescription Opioid Use among Pregnant Women Enrolled in Rhode Island Medicaid

Objective: Our objective was to identify the patterns of opioid use among pregnant women enrolled in RI Medicaid. Methods: This study used linked RI Medicaid and RI Birth Certificate data from 01/01/2006 to 12/31/2016. We examined temporal trends of prescription opioid dispensings and identified risk factors associated with opioids use during pregnancy. Results: Among 25,500 RI Medicaid enrolled pregnant women who delivered a live baby from 2008 to 2016, 1,914 (7.5%) received at least one prescription for an opioid medication during pregnancy, 810 (3.2%) were during the first trimester, 633 (2.5%) during the second trimester, and 866 (3.4%) during the third trimester. Of these, 213 (0.8%) women received 3 or more opioids during pregnancy. The prevalence of prescription opioids dispensed in pregnant women increased from 4.9% in 2008 to 9.6% in 2015 (β SD: 0.66 0.28, P=0.05). Conclusions: Prescription opioid use during pregnancy has increased among women enrolled in RI Medicaid

Measurement of the Cotton-Mouton effect in nitrogen, oxygen, carbon dioxide, argon, and krypton with the Q & A apparatus

Experiments for vacuum birefringence and vacuum dichroism have been set up with high-finesse high magnetic experimental apparatuses, which seem to be ideal for small gaseous Cotton-Mouton effect (CME) measurements. PVLAS Collaboration has measured CMEs in krypton, xenon and neon at the wavelength of 1064 nm. In this Letter, we report on our measurement of CMEs in nitrogen, oxygen, carbon dioxide, argon, and krypton at the same wavelength in a magnetic field B = 2.3 T at pressure P = 0.5-300 Torr and temperature T = 295-298 K. Our results agree with the PVLAS results in the common cases.Comment: 8 pages, 2 tables, 5 figures, submitted to Chemical Physics Letters. Some modifications are made in the revision according to the referee's comments: Donotations in equations are unified. Error in quoting numbers in 2 places in Table 2 is corrected. Uncertainty in modulation depth is included in the total systematic error. References are order re-arrange

The BMV experiment : a novel apparatus to study the propagation of light in a transverse magnetic field

In this paper, we describe in detail the BMV (Bir\'efringence Magn\'etique du Vide) experiment, a novel apparatus to study the propagation of light in a transverse magnetic field. It is based on a very high finesse Fabry-Perot cavity and on pulsed magnets specially designed for this purpose. We justify our technical choices and we present the current status and perspectives.Comment: To be published in the European Physical Journal

Micromechanical Properties of Injection-Molded Starch–Wood Particle Composites

The micromechanical properties of injection molded starch–wood particle composites were investigated as a function of particle content and humidity conditions. The composite materials were characterized by scanning electron microscopy and X-ray diffraction methods. The microhardness of the composites was shown to increase notably with the concentration of the wood particles. In addition,creep behavior under the indenter and temperature dependence were evaluated in terms of the independent contribution of the starch matrix and the wood microparticles to the hardness value. The influence of drying time on the density and weight uptake of the injection-molded composites was highlighted. The results revealed the role of the mechanism of water evaporation, showing that the dependence of water uptake and temperature was greater for the starch–wood composites than for the pure starch sample. Experiments performed during the drying process at 70°C indicated that the wood in the starch composites did not prevent water loss from the samples.Peer reviewe

Validation of the Behavioural Regulation in Exercise Questionnaire-2 for adults with chronic musculoskeletal pain

Sanchez, Jennifer/0000-0001-8448-0678WOS: 000442017800003PubMed: 32133037Background/Aims: The Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) has demonstrated reliability and validity in the general population; yet the psychometric properties have not been tested among rehabilitation populations, such as persons experiencing chronic musculoskeletal pain. The objective of the current study was to examine the factorial structure and psychometric properties of the BREQ-2 in a sample of adults with chronic musculoskeletal pain. Methods: Adults with chronic musculoskeletal pain (n=211) were recruited from clinical and community networks in the United States. Data were collected using a cross-sectional online survey and analysed using confirmatory factor analysis, multiple indicators multiple causes analysis, and correlational techniques. Participants completed the BREQ-2 and other measures relevant to self-determination theory, including outcome expectancies, self-efficacy and family and friend support for physical activity and exercise. Findings: Results indicated the intercorrelated model fit the data well. The five factors of amotivation, external regulation, introjected regulation, identified regulation and intrinsic regulation toward physical activity and exercise demonstrated good reliability and construct validity. Conclusions: This study provides evidence of factorial and construct validity for the BREQ-2 among people with chronic musculoskeletal pain. Implications for rehabilitation practitioners and researchers are discussed.National Institute on Disability and Rehabilitation Research of the U.S. Department of Education [H133B100034]; National Institute of Mental HealthUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Institute of Mental Health (NIMH) [T32 MH073553-11]This work was supported by the National Institute on Disability and Rehabilitation Research of the U.S. Department of Education under Grant H133B100034 and the National Institute of Mental Health Grant under Grant T32 MH073553-11

Mental health treatment among older adults with mental illness on parole or probation

Abstract Background The number of older adults on parole and probation is growing at an unprecedented rate, yet little is known about the mental health needs and treatment utilization patterns among this group. The objective of this study is to compare the prevalence of serious or moderate mental illness (SMMI), and the proportion of those with SMMI who receive mental health treatment, among community-dwelling older adults on correctional supervision (parole or probation) vs. not on correctional supervision. Methods Design: Cross-sectional analysis of data from the 2008–2014 National Surveys for Drug Use and Health (NSDUH). Setting: Population-based national survey data. Participants: Older adults (age ≥ 50) who participated in the NSDUH between 2008 and 2014 (n = 44,624). Participants were categorized according to whether they were on parole or probation during the 12 months prior to survey completion (n = 379) vs. not (n = 44,245). Measurements: Probable SMMI was defined using a validated measure in the NSDUH. Mental health treatment included any outpatient mental health services or prescriptions over the 12 months prior to survey completion. We compared the prevalence of SMMI, and the proportion of those with SMMI who received any treatment, by correctional status. Results Overall, 7% (N = 3266) of participants had SMMI; the prevalence was disproportionately higher among those on parole or probation (21% vs. 7%, p <  0.001). Sixty-two percent of those with SMMI received any mental health treatment, including 81% of those on parole or probation and 61% of those who were not (p <  0.001). This result remained statistically significant after logistic regression accounted for differences in sociodemographics and health. Conclusions SMMI is disproportionally prevalent among older adults on parole or probation, and community correctional supervision programs may be facilitating linkages to needed community-based mental health treatment
