Sets of Priors Reflecting Prior-Data Conflict and Agreement
In Bayesian statistics, the choice of prior distribution is often debatable,
especially if prior knowledge is limited or data are scarce. In imprecise
probability, sets of priors are used to accurately model and reflect prior
knowledge. This has the advantage that prior-data conflict sensitivity can be
modelled: Ranges of posterior inferences should be larger when prior and data
are in conflict. We propose a new method for generating prior sets which, in
addition to prior-data conflict sensitivity, allows to reflect strong
prior-data agreement by decreased posterior imprecision.Comment: 12 pages, 6 figures, In: Paulo Joao Carvalho et al. (eds.), IPMU

Genetics of Severe Obesity
Purpose of Review
This review aims to present current information on genes underlying severe obesity, with the main emphasis on the three genes LEP, LEPR and MC4R.
Recent Findings
There is a substantial amount of evidence that variants in at least ten different genes are the cause of severe monogenic obesity. The majority of these are involved in the leptin-melanocortin signalling pathway. Due to the frequency of some of the identified variants, it is clear that monogenic variants also make a significant contribution to common obesity.
Summary
The artificial distinction between rare monogenic obesity and common polygenic obesity is now obsolete with the identification of MC4R variants of strong effect in the general population.

Assessing soil N availability indices - is inorganic N enough?
Non-Peer ReviewedAssessing soil N availability is complicated enormously by the complexity of the N-cycle.
Over the years, several methods of estimating potentially available N have been suggested. In an
ongoing study, we have been assessing the suitability of a number of these methods for
predicting potential crop response to fertilizer N. In particular, we correlated amino-sugar N
levels to wheat yield across a variable landscape. This relatively new soil N test appears to be
sensitive to changes in organic matter quality as related to landscape position and holds some
promise for assessing potentially available N. The results presented here are preliminary
Clinicopathological determinants of an elevated systemic inflammatory response following elective potentially curative resection for colorectal cancer
Introduction:
The postoperative systemic inflammatory response (SIR) is related to both long- and short-term outcomes following surgery for colorectal cancer. However, it is not clear which clinicopathological factors are associated with the magnitude of the postoperative SIR. The present study was designed to determine the clinicopathological determinants of the postoperative systemic inflammatory response following colorectal cancer resection.
Methods:
Patients with a histologically proven diagnosis of colorectal cancer who underwent elective, potentially curative resection during a period from 1999 to 2013 were included in the study (n = 752). Clinicopathological data and the postoperative SIR, as evidenced by postoperative Glasgow Prognostic Score (poGPS), were recorded in a prospectively maintained database.
Results:
The majority of patients were aged 65 years or older, male, were overweight or obese, and had an open resection. After adjustment for year of operation, a high day 3 poGPS was independently associated with American Society of Anesthesiologists (ASA) grade (hazard ratio [HR] 1.96; confidence interval [CI] 1.25–3.09; p = 0.003), body mass index (BMI) (HR 1.60; CI 1.07–2.38; p = 0.001), mGPS (HR 2.03; CI 1.35–3.03; p = 0.001), and tumour site (HR 2.99; CI 1.56–5.71; p < 0.001). After adjustment for year of operation, a high day 4 poGPS was independently associated with ASA grade (HR 1.65; CI 1.06–2.57; p = 0.028), mGPS (HR 1.81; CI 1.22–2.68; p = 0.003), NLR (HR 0.50; CI 0.26–0.95; p = 0.034), and tumour site (HR 2.90; CI 1.49–5.65; p = 0.002).
Conclusions:
ASA grade, BMI, mGPS, and tumour site were consistently associated with the magnitude of the postoperative systemic inflammatory response, evidenced by a high poGPS on days 3 and 4, in patients undergoing elective potentially curative resection for colorectal cancer

Bean quest 2002: the final frontier
Non-Peer ReviewedThe agronomic, economic and genetic pieces of the jigsaw puzzle for developing a dryland bean industry in Saskatchewan are coming together. In 2002, dryland bean growers in Southeastern Saskatchewan made a profit using new varieties of black and pinto bean. Much of the credit for this goes to the hard work, homework, and perseverance of the crop clubs that have developed around the province in the past few years. The research and development effort of the past 10 years is finally starting to pay dividends in the dry bean sector of the pulse industry. In this paper, we would like to briefly summarize some of the key results of various dry bean research and development projects that have been underway in the past few years
Patterns of antihypertensive prescribing, discontinuation and switching among a Hong Kong Chinese population from over one million prescriptions
Hypertension is an alarming public health problem among Chinese. The present study evaluated the prescribing patterns, discontinuation and switching profiles of antihypertensive agents and their associated factors in one Hong Kong Chinese population. Data were retrieved from computerized records for patients prescribed anti-hypertensive agents in government primary care clinics of Hong Kong from January, 2004 to June, 2007. A total of 1,069,836 antihypertensive drug visits, representing 67,028 patients, were analyzed. The most commonly prescribed drugs were Calcium Channel Blockers (CCBs) (49%), b-Blockers (BBs) (46%) and Angiotensin-Converting Enzyme Inhibitors (ACEIs) (19%). Thiazide diuretic prescribing was low (13%) and on the decline (14% in 2004 to 12% in 2007). Prescribing of ACEIs was rising (16% in 2004 to 23% in 2007). Patients’ age, gender, and socio-economic status were independent predictors of class of anti-hypertensive prescribed but explained less than 3.5% of the variation observed. Drug discontinuation was highest for BBs (21%) and lowest for CCBs (12%). The high rates of discontinuation in BBs remained apparent after controlling for confounding variables. Switching was less common than discontinuation and was most likely with thiazide diuretics. To summarize, prescribing of CCBs and BBs were high and that of thiazide diuretics particularly low in this Chinese population when compared with international trends. CCBs may be a particularly favorable antihypertensive treatment in Chinese, given the high discontinuation rates of BBs and international guidelines advising against the use of BBs as first-line therapy. The low use of thiazide diuretics warrants further clinical and cost effectiveness studies among Chinese
Antecedent factors impacting country of origin (COO): an investigation into food provenance in China
This paper reports a study that sought to investigate the antecedent factors influencing consumer COO perceptions. A review of the literature revealed that most previous studies consider these factors independently, however, it is now widely accepted that consumer decision making does not involve the consideration of variables one-at-a-time but rather as a small group of factors often referred to as the evoked set. This study, therefore, set out to fill a gap in the knowledge regarding the factors influencing consumer COO when considered collectively. A model of the antecedent factors impacting COO was developed from the literature and a three stage methodology involving both qualitative and quantitative techniques was then used to test the model. The findings not only confirm COO as an important factor in the decision making process of Chinese consumers when purchasing food products but go on to suggest that the role played by the antecedent factors of COO is much more complex than the existing literature might suggest. The main limitations of the study related to the work being conducted in just one country (China) and the inherent issues associated with research that is based on sampling. Despite the limitations, the paper makes an original contribution to knowledge regarding antecedent factors impacting COO and presents a number of implications for both practicing marketing managers and academic theorists
