An Exploration into the Motivation for Gluten Avoidance in the Absence of Coeliac Disease
Aim: To explore the motivation for gluten avoidance in the absence of coeliac disease (CD) and ascertain what symptoms are triggered by gluten and what beliefs/reasons influence this decision.
Background: Links between physical/psychological symptoms and gluten in CD are well known but less is known about those who self-select a gluten-free diet (GFD) in the absence of CD.
Methods: An empirical study using responses to an anonymous on-line questionnaire. Closed questions were used as a screening tool to exclude participants who had CD, wheat allergy or were following a low FODMAP diet. Data from participants using a GFD in the absence of a medical diagnosis was then analysed using thematic analysis.
Results: 120 initial responses, 87 were completed in full. 23 respondents fulfilled the inclusion criteria for thematic analysis. 7 different themes emerged, including one for signs/symptoms. Other themes identified included difficulties of a GFD, health beliefs, feelings and influence on decision to follow a GFD. Responses indicate that the reasons for gluten avoidance are in the most part reasoned and logical and were based around participants’ self-management of symptoms.
Conclusion: Symptoms included those typical of irritable bowel syndrome (IBS), but also infertility, low mood/energy, immune function and weight management and visual and auditory hallucinations. It appears the majority of responses analysed thematically could fit into the spectrum of non-coeliac gluten sensitivity (NCGS). Findings also suggest more support at all levels of medical care may help patients establish if it is gluten, rather than wheat or FODMAPs particularly fructans that are contributing to signs/symptoms

The Impact of Breakfast in Metabolic and Digestive Health
Aim: The purpose of this study is to explore whether the types and quality of breakfast could influence energy levels
(blood glucose levels) and propose ideal breakfast models.
Background: It is widely considered that a regular breakfast provides a number of health benefits; however, there is no
general scientific agreement regarding what kind of food should be consumed. Evidence supports the importance of
balancing blood glucose levels by low glycaemic index/load (L-GI/L) and increased protein diets, in particular in
metabolic disorders, which non-alcoholic fatty liver disease (NAFLD) has a close relation to.
Patients and methods: This study was conducted by using a valid and standard questionnaire at the University of
Worcester to evaluate the breakfast and dietary habits and energy levels. The Kruskal-Wallis test was used for statistical
analysis.
Results: No significant differences were found either between breakfast consumption, energy levels, types of snack and
amount of caffeine intake in the morning or between types of breakfast, energy levels, types of snack, and amount of
caffeine intake in the morning. However, potential differences in energy levels were found across the groups of
breakfast types: glycaemia (GL) (p=.057) and protein intake (p=.056).
Conclusion: The types and quality of breakfast would be key as regular breakfast consumption alone did not show
adequate health benefits. Lower GL foods and higher protein intake at breakfast were found to be associated with higher
energy levels. It is therefore recommended that breakfast foods should be low in GL and high in protein. These changes
may lead to better health status and prevention of dise
ase, especially metabolic and liver disorders, in the long term
Hospitalization Rates and Predictors of Rehospitalization Among Individuals With Advanced Cancer in the Year After Diagnosis
Purpose Among individuals with advanced cancer, frequent hospitalization increasingly is viewed as a hallmark of poor-quality care. We examined hospitalization rates and individual- and hospital-level predictors of rehospitalization among individuals with advanced cancer in the year after diagnosis. Methods Individuals diagnosed with advanced breast, colorectal, non-small-cell lung, or pancreatic cancer from 2009 to 2012 (N = 25,032) were identified with data from the California Cancer Registry (CCR). After linkage with inpatient discharge data, multistate and log-linear Poisson regression models were used to calculate hospitalization rates and to model rehospitalization in the year after diagnosis, accounting for survival. Results In the year after diagnosis, 71% of individuals with advanced cancer were hospitalized, 16% had three or more hospitalizations, and 64% of hospitalizations originated in the emergency department. Rehospitalization rates were significantly associated with black non-Hispanic (incidence rate ratio [IRR], 1.29; 95% CI, 1.17 to 1.42) and Hispanic (IRR, 1.11; 95% CI, 1.03 to 1.20) race/ethnicity; public insurance (IRR, 1.37; 95% CI, 1.23 to 1.47) and no insurance (IRR, 1.17; 95% CI, 1.02 to 1.35); lower socioeconomic status quintiles (IRRs, 1.09 to 1.29); comorbidities (IRRs, 1.13 to 1.59); and pancreatic (IRR, 2.07; 95% CI, 1.95 to 2.20) and non-small-cell lung (IRR, 1.69; 95% CI, 1.54 to 1.86) cancers versus colorectal cancer. Rehospitalization rates were significantly lower after discharge from a hospital that had an outpatient palliative care program (IRR, 0.90; 95% CI, 0.83 to 0.97) and were higher after discharge from a for-profit hospital (IRR, 1.33; 95% CI, 1.14 to 1.56). Conclusion Individuals with advanced cancer experience a heavy burden of hospitalization in the year after diagnosis. Efforts to reduce hospitalization and provide care congruent with patient preferences might target individuals at higher risk. Future work might explore access to palliative care in the community and related health care use among individuals with advanced cancer
Role of the liver in splanchnic extraction of atrial natriuretic factor in the rat
Mesenteric, hepatic and splanchnic extraction of C-terminal and N-terminal atrial natriuretic factor was investigated in male Sprague-Dawley rats. Plasma concentrations (mean ± S.E.M.) of C-terminal atrial natriuretic factor were 55.0 ± 6.1 fmol/ml, 31.2 ± 4.0 fmol/ml and 23.5 ± 3.3 fmol/ml (n = 12) in the abdominal aorta, the portal vein and the hepatic vein, respectively. N-terminal atrial natriuretic factor plasma levels in these vessels were 3031 ± 756 fmol/ml, 2264 ± 661 fmol/ml and 1618 ± 496 fmol/ml (n = 6), respectively. Although the mesenteric extraction ratio was higher (p < 0.05) for C-terminal atrial natriuretic factor (42% ± 6%) than for N-terminal atrial natriuretic factor (28% ± 4%), there were no significant differences in the hepatic extraction ratio (41% ± 5% vs. 39% ± 6%) and the splanchnic extraction ratio (56% ± 5% vs. 50% ± 7%). These data suggest a major role of the liver in the splanchnic extraction of C-terminal and of N-terminal atrial natriuretic factor in the rat. (HEPATOLOGY 1992;16:790-793
Measurement of the Luminosity in the ZEUS Experiment at HERA II
The luminosity in the ZEUS detector was measured using photons from electron
bremsstrahlung. In 2001 the HERA collider was upgraded for operation at higher
luminosity. At the same time the luminosity-measuring system of the ZEUS
experiment was modified to tackle the expected higher photon rate and
synchrotron radiation. The existing lead-scintillator calorimeter was equipped
with radiation hard scintillator tiles and shielded against synchrotron
radiation. In addition, a magnetic spectrometer was installed to measure the
luminosity independently using photons converted in the beam-pipe exit window.
The redundancy provided a reliable and robust luminosity determination with a
systematic uncertainty of 1.7%. The experimental setup, the techniques used for
luminosity determination and the estimate of the systematic uncertainty are
reported.Comment: 25 pages, 11 figure
Prevalence and burden of chronic bronchitis symptoms: results from the BOLD study
We studied the prevalence, burden and potential risk factors for chronic bronchitis symptoms in the Burden of Obstructive Lung Disease study. Representative population-based samples of adults aged ≥40 years were selected in participating sites. Participants completed questionnaires and spirometry. Chronic bronchitis symptoms were defined as chronic cough and phlegm on most days for ≥3 months each year for ≥2 years. Data from 24 855 subjects from 33 sites in 29 countries were analysed. There were significant differences in the prevalence of self-reported symptoms meeting our definition of chronic bronchitis across sites, from 10.8% in Lexington (KY, USA), to 0% in Ile-Ife (Nigeria) and Blantyre (Malawi). Older age, less education, current smoking, occupational exposure to fumes, self-reported diagnosis of asthma or lung cancer and family history of chronic lung disease were all associated with increased risk of chronic bronchitis. Chronic bronchitis symptoms were associated with worse lung function, more dyspnoea, increased risk of respiratory exacerbations and reduced quality of life, independent of the presence of other lung diseases. The prevalence of chronic bronchitis symptoms varied widely across the studied sites. Chronic bronchitis symptoms were associated with significant burden both in individuals with chronic airflow obstruction and those with normal lung function
Synthesis of Dihydropyridine Spirocycles by Semi-Pinacol-Driven Dearomatization of Pyridines
The identification of the beneficial pharmacokinetic
properties
of aza-spirocycles has led to the routine incorporation of these highly
rigid and three-dimensional structures in pharmaceuticals. Herein,
we report an operationally simple synthesis of spirocyclic dihydropyridines
via an electrophile-induced dearomative semi-pinacol rearrangement
of 4-(1′-hydroxycyclobutyl)pyridines. The various points for
diversification of the spirocyclization precursors, as well as the
synthetic utility of the amine and ketone functionalities in the products,
provide the potential to rapidly assemble medicinally relevant spirocycles
