BACKGROUND: Evidence for the association between posttraumatic stress disorder (PTSD) and gastrointestinal (GI) disorders is mixed, owing in part to methodologic differences across studies. Further, studies which have combined GI disorders or symptoms for examination as one overall category may potentially obscure associations between PTSD and individual GI diagnoses. METHODS: This nationwide cohort study examined the incidence of all major non-malignant GI disorders in patients with a prior PTSD diagnosis (n = 4,076), compared to the general population incidence from 1995-2013, using Danish medical registry data...

INTRODUCTION: Ex vivo measurement of ascending aortic biomechanical properties may help understand the risk for rupture or dissection of dilated ascending aortas. A validated in vivo method that can predict aortic biomechanics does not exist. Speckle tracking transesophageal echocardiography (TEE) has been used to measure ventricular stiffness; we sought to determine whether speckle TEE could be adapted to estimate aortic stiffness in vivo and compare these findings with those obtained by ex vivo tissue measurements...

BACKGROUND: Selective BCL2 inhibition with venetoclax has substantial activity in patients with relapsed or refractory chronic lymphocytic leukaemia. Combination therapy with rituximab enhanced activity in preclinical models. The aim of this study was to assess the safety, pharmacokinetics, and activity of venetoclax in combination with rituximab. METHODS: Adult patients with relapsed or refractory chronic lymphocytic leukaemia (according to the 2008 Modified International Workshop on CLL guidelines) or small lymphocytic lymphoma were eligible for this phase 1b, dose-escalation trial...

Inflammation is a consequence of chronic kidney disease (CKD) and is associated with adverse outcomes in many clinical settings. Inflammation stimulates production of fibroblast growth factor 23 (FGF23), high levels of which are independently associated with mortality in CKD. Few large-scale prospective studies have examined inflammation and mortality in patients with CKD, and none tested the interrelationships among inflammation, FGF23, and risk of death. Therefore, we conducted a prospective investigation of 3875 participants in the Chronic Renal Insufficiency Cohort (CRIC) study with CKD stages 2 to 4 to test the associations of baseline plasma interleukin-6, high-sensitivity C-reactive protein, and FGF23 levels with all-cause mortality, censoring at the onset of end-stage renal disease...

INTRODUCTION: Air, land, and sea transportation can facilitate rapid spread of infectious diseases. In May 2015 the Pan American Health Organization (PAHO) issued an alert regarding the first confirmed Zika virus infection in Brazil. As of March 8, 2016, the U.S. Centers for Disease Control and Prevention (CDC) had issued travel notices for 33 countries and 3 U.S. territories with local Zika virus transmission. METHODS: Using data from five separate datasets from 2014 and 2015, we estimated the annual number of passenger journeys by air and land border crossings to the United States from the 33 countries and 3 U...

Tamoxifen therapy for estrogen receptor-positive breast cancer reduces the risk of recurrence by approximately one-half. Cytochrome P-450 2D6, encoded by the polymorphic cytochrome P-450 2D6 gene (CYP2D6), oxidizes tamoxifen to its most active metabolites. Steady-state concentrations of endoxifen (4-hydroxy-N-desmethyltamoxifen), the most potent antiestrogenic metabolite, are reduced in women whose CYP2D6 genotypes confer poor enzyme function. Thirty-one studies of the association of CYP2D6 genotype with breast cancer survival have yielded heterogeneous results...

Higher diet-dependent nonvolatile acid load is associated with faster chronic kidney disease (CKD) progression, but most studies have used estimated acid load or measured only components of the gold standard, net acid excretion (NAE). Here we measured NAE as the sum of urine ammonium and titratable acidity in 24-hour urines from a random subset of 980 participants in the Chronic Renal Insufficiency Cohort (CRIC) Study. In multivariable models accounting for demographics, comorbidity and kidney function, higher NAE was significantly associated with lower serum bicarbonate (0...

Turner syndrome (TS) is associated with decreased bone mineral density and increased fracture rate. However, the developmental trajectory of bone density or body composition in patients with TS is still unclear. The present study tested the hypothesis that different karyotypes and/or age contributes to abnormal body composition and decreased bone mineral status parameters in patients with TS. This study included 24 girls with TS, in which 13 girls exhibited X0 karyotype and 11 had mosaicism. Quantitative ultrasound (QUS) assessed the bone mineral status of the calcaneus, including bone mineral density (BMD), amplitude-dependent speed of sound (AD-SOS), broadband ultrasound attenuation (BUA) and InBody 770 assessed body composition...

The question of what constitutes the most appropriate control group in child psychopathology research remains a vexed question as well as one of the most common issues raised in the referees' reports I read as an editor of JCPP. Yet its importance is often overlooked by authors as they reflect on potential sources of bias in their studies. There is an abundant literature on this question (Rothman, Greenland, & Lash, 2008) that highlights the key issues and pitfalls for research in our field.

Generalist parasites can strongly influence interactions between native and invasive species. Host competence can be used to predict how an invasive species will affect community disease dynamics; the addition of a highly competent, invasive host is predicted to increase disease. However, densities of invasive and native species can also influence the impacts of invasive species on community disease dynamics. We examined whether information on host competence alone could be used to accurately predict the effects of an invasive host on disease in native hosts...

Azuliporphyrins are intriguing porphyrin analogues that incorporate an azulene ring in place of a pyrrolic unit. This system undergoes regioselective oxidation reactions and favors the formation of stable organometallic derivatives. Reaction of meso-unsubstituted azuliporphyrins with Co2(CO)8 or CoCl2·6H2O gave 21-oxyazuliporphyrins, while Cu(OAc)2 produced the corresponding copper(ii) complexes. Treatment of an oxyazuliporphyrin with Ni(OAc)2 or Pd(OAc)2 afforded analogous nickel(ii) and palladium(ii) derivatives...

The objective of this work is to compare the performances of two electroencephalogram based indices for detecting loss of consciousness and loss of response to nociceptive stimulation. Specifically, their behaviour after drug induction and during recovery of consciousness was pointed out. Data was recorded from 140 patients scheduled for general anaesthesia with a combination of propofol and remifentanil. The qCON 2000 monitor (Quantium Medical, Barcelona, Spain) was used to calculate the qCON and qNOX. Loss of response to verbal command and loss of eye-lash reflex were assessed during the transition from awake to anesthetized, defining the state of loss of consciousness...

PURPOSE: We hypothesize that the typically narrower palpebral apertures of East Asian eyes in combination with the narrowing of this aperture during down-gaze combine to reduce light levels and image contrast in the inferior retina during near work, thus creating peripheral deprivation in these eyes that could generate deprivation myopia in children culturally encouraged to perform near work. METHODS: We photographed the right eyes of 53 Chinese children during down-gaze (from 10 to 40 degrees) from the fixation point and the primary gaze position...

Latin America has 23 countries ranging from Mexico, Central America, South America and the Caribbean, of these 19 countries are considered by the WHO as countries with high and very high risk, one of the similarities of our countries is poor access to services health and medicine, resulting from poor government investment in health as the amount used in this sector occupies only the best 3% of the national budget and gross domestic product.Thus we know that the prevalence of hypertension varies widely from country to country and from city to city, presenting in Guatemala a prevalence of 40%, while in other countries in the area ranges between 25 and 35%, most complicated problem is that within the same country as the population this prevalence can vary greatly and have a different impact between populationsTherefore we know that the impact of cardiovascular disease within the range of non-communicable diseases occupies at least 30% and of these about 70% occupied countries of low and moderate income...

Point-of-care (POC) technologies have proved valuable in cancer detection, diagnosis, monitoring, and treatment in the developed world, and have shown promise in low-and-middle-income countries (LMIC) as well. Despite this promise, the unique design constraints presented in low-resource settings, coupled with the variety of country-specific regulatory and institutional dynamics, have made it difficult for investigators to translate successful POC cancer interventions to the LMIC markets. In response to this need, the National Cancer Institute has partnered with the National Institute of Biomedical Imaging and Bioengineering to create the National Institutes of Health Affordable Cancer Technologies (ACTs) program...

To advance the development of point-of-care technology (POCT), the National Institute of Biomedical Imaging and Bioengineering established the POCT Research Network (POCTRN), comprised of Centers that emphasize multidisciplinary partnerships and close facilitation to move technologies from an early stage of development into clinical testing and patient use. This paper describes the POCTRN and the three currently funded Centers as examples of academic-based organizations that support collaborations across disciplines, institutions, and geographic regions to successfully drive innovative solutions from concept to patient care...
