OBJECTIVE: Although anti-tumour necrosis factor alpha (anti-TNFα) therapies represent a major breakthrough in IBD therapy, their cost-benefit ratio is hampered by an overall 30% non-response rate, adverse side effects and high costs. Thus, finding predictive biomarkers of non-response prior to commencing anti-TNFα therapy is of high value. DESIGN: We analysed publicly available whole-genome expression profiles of colon biopsies obtained from multiple cohorts of patients with IBD using a combined computational deconvolution-meta-analysis paradigm which allows to estimate immune cell contribution to the measured expression and capture differential regulatory programmes otherwise masked due to variation in cellular composition...

We report on a study conducted in Guangdong Province, China, to characterize behaviors and perceptions associated with transmission of pathogens with pandemic potential in highly exposed human populations at the animal-human interface. A risk factor/exposure survey was administered to individuals with high levels of exposure to wildlife. Serological testing was performed to evaluate prior infection with several wildlife viral pathogens. Follow up serology was performed on a subset of the cohort as well as close contacts of individuals...

The use of veno-venous extracorporeal membrane oxygenation (VV ECMO) in adults with respiratory failure has steadily increased during the past decade. Recent literature has demonstrated variable outcomes with the use of extended ECMO. The purpose of this study is to evaluate survival to hospital discharge in patients with extended ECMO runs compared with patients with short ECMO runs at a tertiary care ECMO referral center. We retrospectively reviewed all patients on VV ECMO for respiratory failure between August 2014 and February 2017...

The current study compares health care professionals' beliefs about vaccination statements with the beliefs of a sample of individuals from the general population. Students and faculty within a medical school ( n = 58) and a sample from the general population in the United States ( n = 177) were surveyed regarding their beliefs about vaccinations. Participants evaluated statements about vaccinations (both supporting and opposing), and indicated whether they thought the general population would agree with them...

Glucagon levels increase under homeostatic, fasting conditions, promoting the release of glucose from the liver by accelerating the breakdown of glycogen (also known as glycogenolysis). Glucagon also enhances gluconeogenic flux, including from an increase in the hepatic consumption of amino acids. In type 2 diabetes, dysregulated glucagon signaling contributes to the elevated hepatic glucose output and fasting hyperglycemia that occur in this condition. Yet, the mechanism by which glucagon stimulates gluconeogenesis remains incompletely understood...

INTRODUCTION: In this era of patient-centered care, telepsychiatry (TP; video or synchronous) provides quality care with outcomes as good as in-person care, facilitates access to care, and leverages a wide range of treatments at a distance. METHOD: This conceptual review article explores TP as applied to newer models of care (e.g., collaborative, stepped, and integrated care). RESULTS: The field of psychosomatic medicine (PSM) has developed clinical care models, educates interdisciplinary team members, and provides leadership to clinical teams...

Increasing evidence suggests a role for excessive intake of fructose in the Western diet as a contributor to the current epidemics of metabolic syndrome and obesity. Hereditary fructose intolerance (HFI) is a difficult and potentially lethal orphan disease associated with impaired fructose metabolism. In HFI, the deficiency of a particular aldolase, aldolase B, results in the accumulation of intracellular phosphorylated fructose thus leading to phosphate sequestration and depletion, increased ATP turnover and a plethora of conditions leading to clinical manifestations including fatty liver, hyperuricemia, Fanconi syndrome and severe hypoglycemia...

We have improved our microfluidic cell culture device that generates an in vitro landscape of stress heterogeneity. We now can do continuous observations of different cancer cell lines and carry out downstream analysis of cell phenotype as a function of position on the stress landscape. We use this technology to probe adaption and evolution dynamics in prostate cancer cell metapopulations under a stress landscape of a chemotherapeutic drug (docetaxel). The utility of this approach is highlighted by analysis of heterogenous prostate cancer cell motility changes as a function of position in the stress landscape...

OBJECTIVE: Women in veterinary occupations are routinely exposed to potential reproductive hazards, yet research into their birth outcomes is limited. We conducted a population-based retrospective cohort study of the association between maternal veterinary occupation and adverse birth outcomes. METHODS: Using Washington State birth certificate, fetal death certificate and hospital discharge data from 1992 to 2014, we compared birth outcomes of mothers in veterinary professions (n=2662) with those in mothers in dental professions (n=10 653) and other employed mothers (n=8082)...

Toxicity resulting from accumulation of sugar-phosphate molecules is an evolutionarily conserved phenomenon, observed in multiple bacterial and eukaryotic systems, including a number of human diseases. However, the molecular mechanisms involved in sugar-phosphate toxicity remain unclear. Using the model eukaryote S. cerevisiae , we developed two systems to accumulate human disease-associated sugar-phosphate species. One system utilizes constitutive expression of galactose permease and galactose kinase to accumulate galactose-1-phosphate, while the other system utilizes constitutive expression of a mammalian ketohexokinase gene to accumulate fructose-1-phosphate...

Cortical networks are composed of excitatory projection neurons and inhibitory interneurons. Finding the right balance between the two is important for controlling overall cortical excitation and network dynamics. However, it is unclear how the correct number of cortical interneurons (CIs) is established in the mammalian forebrain. CIs are generated in excess from basal forebrain progenitors, and their final numbers are adjusted via an intrinsically determined program of apoptosis that takes place during an early postnatal window...

BACKGROUND: Breastfeeding is fundamental to maternal and child health and is the most cost-effective intervention to reduce child mortality. Pasteurized human donor milk (HDM) is increasingly provided for term newborns requiring temporary supplementation. Few studies examine maternal perspectives on supplementation of term newborns. MATERIALS AND METHODS: We conducted semistructured in-person interviews with mothers of term newborns (n = 24) during postpartum hospitalization...

One carbon metabolism is regulated by the availability of nutrients known as methyl donors, and disruption of this pathway can affect multiple physiological systems. DNA methylation, critical for the regulation of gene expression, is linked to one carbon metabolism, and can be altered by perinatal diet. In the current study, dams (n=12/group) were fed HF or standard control (SC) diet through pregnancy and lactation, and male and female offspring were then fed either SC or methyl donor supplemented diet (MDS) between 3 and 6 weeks of age (n=20-26/group)...

BACKGROUND: The sliding sign (the relative motion between the abdominal and uterine wall as assessed by ultrasonography) may help identify severe intra-abdominal adhesions before repeat cesarean delivery. METHODS: We conducted a prospective observational study of scheduled repeat cesarean deliveries. Using transabdominal ultrasonography, while the parturient breathed deeply, the ultrasonographer recorded a video clip in a sagittal plane lateral to the umbilicus...

Excessive consumption of sweets is a risk factor for metabolic syndrome. A major chemical feature of sweets is fructose. Despite strong ties between fructose and disease, the metabolic fate of fructose in mammals remains incompletely understood. Here we use isotope tracing and mass spectrometry to track the fate of glucose and fructose carbons in vivo, finding that dietary fructose is cleared by the small intestine. Clearance requires the fructose-phosphorylating enzyme ketohexokinase. Low doses of fructose are ∼90% cleared by the intestine, with only trace fructose but extensive fructose-derived glucose, lactate, and glycerate found in the portal blood...

Folates enable the activation and transfer of one-carbon units for the biosynthesis of purines, thymidine and methionine. Antifolates are important immunosuppressive and anticancer agents. In proliferating lymphocytes and human cancers, mitochondrial folate enzymes are particularly strongly upregulated. This in part reflects the need for mitochondria to generate one-carbon units and export them to the cytosol for anabolic metabolism. The full range of uses of folate-bound one-carbon units in the mitochondrial compartment itself, however, has not been thoroughly explored...
