OBJECTIVE: To identify risk factors for maternal morbidity after previable prelabor rupture of membranes (PROM). METHODS: We conducted a case-control study of singleton and twin pregnancies complicated by previable PROM (14.0-22.9 weeks of gestation) at a single tertiary care referral institution, 2000-2015. Pregnancies complicated by fetal anomalies, previable PROM within 2 weeks of chorionic villus sampling or amniocentesis, and those with contraindications to expectant management (eg, chorioamnionitis) were excluded...

The primary aim of this study was to determine whether the levels of obsessive passion (OP) and harmonious passion for a suspended leisure activity contribute to pain catastrophizing and pain intensity in patients undergoing the rehabilitation process. The secondary aim was to examine whether the levels of passion associated with a maintained leisure activity offset the contribution of having a leisure activity suspended to pain intensity and catastrophizing. Ninety-one outpatients from functional rehabilitation units (Mage=37, SD=13...

Moses Chung, Hong Qin, Ronald C Davidson, Lars Groening, Chen Xiao
In an uncoupled linear lattice system, the Kapchinskij-Vladimirskij (KV) distribution formulated on the basis of the single-particle Courant-Snyder invariants has served as a fundamental theoretical basis for the analyses of the equilibrium, stability, and transport properties of high-intensity beams for the past several decades. Recent applications of high-intensity beams, however, require beam phase-space manipulations by intentionally introducing strong coupling. In this Letter, we report the full generalization of the KV model by including all of the linear (both external and space-charge) coupling forces, beam energy variations, and arbitrary emittance partition, which all form essential elements for phase-space manipulations...

AIM: The aim of this study was to explore factors affecting efficacy of treatment of common cold symptoms with an over-the-counter ibuprofen/pseudoephedrine combination product. METHODS: Data from an anonymous survey among 1770 pharmacy customers purchasing the combination product for treatment of own common cold symptoms underwent post-hoc descriptive analysis. Scores of symptoms typically responsive to ibuprofen (headache, pharyngeal pain, joint pain and fever), typically responsive to pseudoephedrine (congested nose, congested sinus and runny nose), considered non-specific (sneezing, fatigue, dry cough, cough with expectoration) and comprising all 11 symptoms were analysed...

A realistic mock circulatory system (MCS) could be a valuable in vitro testbed to study human circulatory hemodynamics. The objective of this study was to design a MCS replicating the pulmonary arterial circulation, incorporating an anatomically representative arterial model suitable for testing clinically relevant scenarios. A second objective of the study was to ensure the system's compatibility with magnetic resonance imaging (MRI) for additional measurements. A latex pulmonary arterial model with two generations of bifurcations was manufactured starting from a 3D-printed mold reconstructed from patient data...

Objective: to understand the meaning of humanized care in intensive care units considering the experience of the multidisciplinary team. Method: descriptive and exploratory qualitative research. For this purpose, we conducted semi-structured interviews with 24 professionals of the heath-care team, and, after transcription, we organized the qualitative data according to content analysis. Results: from two main categories, we were able to understand that humanized care is characterized in the actions of health-care: effective communication, team work, empathy, singularity, and integrality; and mischaracterized in the management processes, specifically in the fragmentation of the work process and health-care, in the precarious work conditions, and in differing conceptual aspects of the political proposal of humanization...

A vast number of stimuli use the Ras/Raf/MEK/ERK signaling cascade to transmit signals from their cognate receptors, in order to regulate multiple cellular functions, including key processes such as proliferation, cell cycle progression, differentiation, and survival. The duration, intensity and specificity of the responses are, in part, controlled by the compartmentalization/subcellular localization of the signaling intermediaries. Ras proteins are found in different plasma membrane microdomains and endomembranes...

Extracellular signal-regulated kinase (ERK) regulates various cellular functions through phosphorylation of numerous downstream substrates, which have not yet been fully characterized. To date, several phosphoproteomic approaches have been employed to identify novel substrates for ERK. In this chapter, we describe a method to globally identify ERK substrates by combining immobilized metal affinity chromatography (IMAC) and two-dimensional difference gel electrophoresis (2D-DIGE) followed by mass spectrometry...

The analysis of speech onset times has a longstanding tradition in experimental psychology as a measure of how a stimulus influences a spoken response. Yet the lack of accurate automatic methods to measure such effects forces researchers to rely on time-intensive manual or semiautomatic techniques. Here we present Chronset, a fully automated tool that estimates speech onset on the basis of multiple acoustic features extracted via multitaper spectral analysis. Using statistical optimization techniques, we show that the present approach generalizes across different languages and speaker populations, and that it extracts speech onset latencies that agree closely with those from human observations...

In western Uganda, the landscape surrounding Kibale National Park (KNP) contains households, trading centers, roads, fields, and forest fragments. The mosaic arrangement of these landscape features is thought to enhance human-primate interaction, leading to primate population declines and increased bi-directional disease transmission. Using a social-ecological systems research framework that captures the complexity of interaction among people, wildlife, and environment, we studied five forest fragments near KNP and conducted intensive on-the-ground mapping to identify locations of human-primate spatial overlap...

Complex regulatory landscapes control the pleiotropic transcriptional activities of developmental genes. For most genes, the number, location and dynamic of their associated regulatory elements are unknown. In this work we characterized the three-dimensional chromatin micro-architecture and regulatory landscape of 446 limb-associated gene loci in mouse using Capture-C, ChIP-seq and RNA-seq in forelimb, hindlimb at three developmental stages and midbrain. The fine mapping of chromatin interactions revealed a strong preference for functional genomic regions such as repressed or active domains...

INTRODUCTION: Lung adenocarcinoma (ADC) with micropapillary pattern have been reported to have a poor prognosis. However, few studies have reported on the imaging-based identification of micropapillary component, which were all subjective studies dealing with qualitative CT variables. We aimed to explore imaging phenotyping using a radiomics approach for predicting micropapillary pattern within lung ADC METHODS: We enrolled 339 patients who underwent complete resection for lung ADC. Histologic subtypes and grades of the ADCs were classified...

BACKGROUND/PURPOSE: Acute kidney injury (AKI) is a frequent complication of severe burn injury and is associated with mortality. The definition of AKI was modified by the Kidney Disease Improving Global Outcomes Group in 2012. So far, no study has compared the outcome accuracy of the new AKI staging guidelines with that of the complex score system. Hence, we compared the accuracy of these approaches in predicting mortality. METHODS: This was a post hoc analysis of prospectively collected data from an intensive care burn unit in a tertiary care university hospital...

We tested the hypothesis that critical intensity in cycling can be determined from a single delta blood lactate in the third minute of a submaximal cycle ergometer trial. Fourteen healthy young men performed four to six constant-power-output trials on a cycle ergometer to the limit of tolerance. Critical intensity was calculated via a linear model and subsequently validated. Lactate was measured at baseline and at 3 min from exercise onset. Delta lactate was the difference between these measures. Based on individual trials, we obtained the delta lactate-% validated critical intensity relationship and thereafter an estimate of critical intensity was computed...

We report a case of anti-N-methyl-D-aspartate-receptor (anti-NMDAR) encephalitis associated with an immature teratoma developed in a 38-year-old woman. Positron emission tomography (PET) revealed focal intense uptake of F-fluorodeoxyglucose in an area of the brain corresponding to the right medial temporal lobe as well as an intrapelvic tumor. After the PET examination, the patient complained of disorientation and short-term memory loss. The ovarian tumor was resected and diagnosed as an immature teratoma. The cerebrospinal fluid analysis was positive for anti-NMDAR antibody...
