Cannabis use is common and increasing among women in the United States. State policies are changing with a movement towards decriminalization and legalization. We explore the implications of cannabis liberalization for maternal and child health. Most women who use cannabis quit or cut back during pregnancy. Although women are concerned about the possible health effects of cannabis, providers do a poor job of counseling. There is a theoretical potential for cannabis to interfere with neurodevelopment, however human data have not identified any long-term or long lasting meaningful differences between children exposed in utero to cannabis and those not...

A previous theory of separation of motions of core and valence fractions of electrons in a molecule [J. R. Mohallem et al., Chem. Phys. Lett. 501, 575 (2011)] is invoked as basis for the useful concept of Atoms-in-Molecules (AIM) in the stockholder scheme. The output is a new tool for the analysis of the chemical bond that identifies core and valence electron density fractions (core-valence stockholder AIM (CVSAIM)). One-electron effective potentials for each atom are developed, which allow the identification of the parts of the AIM which move along with the nuclei (cores)...

INTRODUCTION: Depression among university students must be screened with valid instruments. The Patient Health Questionnaire (PHQ-9) is reliable and valid for screening depression in a university context; however, its psychometric performance in Colombia is unknown. OBJECTIVE: To estimate the reliability and dimensionality of PHQ-9 as a screening instrument for depressive symptoms among health sciences students of a university in Cartagena, Colombia.Materials y methods: We analyzed the factorial structure and reliability of the PHQ-9 in a sample of 550 students for expected prevalence of clinically-meaningful depressive symptoms (CMDS) of 25% with a confidence level of 95% and an error level of 3%...

Recurrence of bladder cancer can occur repeatedly in the same patient after treatment of the primary tumor. Models predicting the risk of a next recurrence may inform individualized decision-making on surveillance frequency. We aimed to assess the usefulness of extensions of the Cox proportional hazards model for repeated events in this context. We analyzed 531 Dutch patients with bladder cancer (1990-2012) with information on 7 pre-specified predictors at the time of diagnosing the primary and recurrent tumors...

Background Endometriosis is a chronic, estrogen-dependent condition that causes dysmenorrhea and pelvic pain. Elagolix, an oral, nonpeptide, gonadotropin-releasing hormone (GnRH) antagonist, produced partial to nearly full estrogen suppression in previous studies. Methods We performed two similar, double-blind, randomized, 6-month phase 3 trials (Elaris Endometriosis I and II [EM-I and EM-II]) to evaluate the effects of two doses of elagolix - 150 mg once daily (lower-dose group) and 200 mg twice daily (higher-dose group) - as compared with placebo in women with surgically diagnosed endometriosis and moderate or severe endometriosis-associated pain...

We describe optimized fragmentation schemes and data analysis strategies substantially enhancing the depth and accuracy in identifying protein cross-links using non-restricted whole proteome databases. These include a novel hybrid data acquisition strategy to sequence cross-links at both MS2 and MS3 level and a new algorithmic design XlinkX v2.0 for data analysis. As proof-of-concept we investigated proteome-wide protein interactions in E. coli and HeLa cell lysates, respectively, identifying 1,158 and 3,301 unique cross-links at ∼1% false discovery rate...

Acutely ill patients are often treated on site instead of being transported to hospital, so wide-ranging professional competence is required from staff. The aim of this study was to describe and produce new information about out-of-hospital emergency care providers' competence, skills and willingness to engage in self-development activities, and to uncover challenges experienced by care providers in the midst of changing work practices. A quantitative questionnaire was sent to out-of-hospital emergency care providers (N = 142, response rate 53%) of one Finnish hospital district...

INTRODUCTION: Feedback is an essential part of the learning process, and students expect their feedback to be personalised, meaningful and timely. Objective Structured Clinical Examination (OSCE) assessments allow examiners to observe students carefully over the course of a number of varied station types, across a number of clinical knowledge and skill domains. They therefore present an ideal opportunity to record detailed feedback which allows students to reflect on and improve their performance...

AIM: Validation of sequencing-based DNA methylation data is an important step for meaningful translation of findings. However, there has been limited assessment of different platforms to validate methylation data from next generation sequencing. METHODS: We performed a comparative methylation analysis between the genome-wide platform of reduced representation bisulfite sequencing with a targeted, Sequenom EpiTyper platform (four genes were analyzed in 15 cell lines covering 52 CpG sites)...

The way how cognition is conceived and represented in brain functioning will directly impact clinical investigations of people with cognitive difficulties. This is particularly evident in the field of clinical neuropsychology where methodologies and tools are justified on a fundamental level by the theoretical foundations adopted. The present article outlined how the dominant influences of structural and anatomo-clinical theories of memory have led to a particular conception of clinical investigations. We propose to reconsider these dominant methods in favor of a more dynamic and functional representation of memory that would be clinically more appropriate...

This paper presents the results of a qualitative study on the use of sandplay, or sand tray therapy, in the psychotherapeutic process of children who have been sexually abused. A longitudinal study was carried out with seven participants between the ages of 7 and 10 years old. Data was produced during observation of the therapeutic activity over the course of three different phases of treatment, using a rubric created especially for this observation. Three sandplay sessions were recorded: one at the start of therapy, one at the 3-month mark, and the third and final session after 6 months of treatment...

BACKGROUND: A dominant context for pregnant women in the Western world is medical technologies such as ultrasound and screening. It has been argued that such technologies may result in tentative pregnancies, which may be particularly prominent in the first trimester. However, little is known about how women experience early pregnancy. OBJECTIVE: To explore the everyday experiences and expectations of first trimester pregnant women in a medicalized context of comprehensive and routine prenatal screening...

Josephine K Asafu-Adjei, Allan R Sampson
In studies that compare several diagnostic groups, subjects can be measured on certain features and classification trees can be used to identify which of them best characterize the differences among groups. However, subjects may also be measured on additional covariates whose ability to characterize group differences is not meaningful or of interest, but may still have an impact on the examined features. Therefore, it is important to adjust for the effects of covariates on these features. We present a new semi-parametric approach to adjust for covariate effects when constructing classification trees based on the features of interest that is readily implementable...

BACKGROUND: Optimal treatment of inflammatory bowel disease (IBD) requires specialized health care. Patients frequently travel long distances to obtain care for IBD, which may hinder regular care and affect outcomes adversely. METHODS: This study included patients with established Crohn's disease or ulcerative colitis receiving care at a single referral center between January 2005 and August 2016. Distance to our health care center from the zip code of residence was determined for each patient and classified into quartiles...

Purpose The purpose of the study was to describe outcomes that matter to teens with type 1 diabetes. Understanding outcomes that matter to teens could support successful interventions to improve diabetes self-management. Methods Fifty publicly available posts published in the "teen" sections of 2 major diabetes online forums between 2011 and 2013 were analyzed using qualitative research methods. From each post, content and descriptive data (eg, duration of diabetes and age) were collected. Two members of the research team independently used open coding techniques to identify outcomes (defined as impacts or consequences of type 1 diabetes) and organized them into themes and subthemes...

Ecotoxicological assessments often focus on the response of an organism to an individual contaminant under standardised laboratory conditions. Under more ecologically realistic conditions however, individuals are likely to be exposed to a range of environmental conditions that have the potential to act as additional stressors. Multiple stressor experiments improve our understanding of an organism's response to a toxicant under ecologically relevant conditions and provide realistic risk assessment data. To date, there is no standardized method for analysing multiple stressor data using dose-response regression...

Heart failure with preserved ejection fraction (HFpEF) is a common disease with high incidence and increasing prevalence. Patients suffer from functional limitation, poor health-related quality of life, and reduced prognosis. A pilot study in a smaller group of HFpEF patients showed that structured, supervised exercise training (ET) improves maximal exercise capacity, diastolic function, and physical quality of life. However, the long-term effects of ET on patient-related outcomes remain unclear in HFpEF. The primary objective of the Exercise training in Diastolic Heart Failure (Ex-DHF) trial is to investigate whether a 12 month supervised ET can improve a clinically meaningful composite outcome score in HFpEF patients...
