BACKGROUND/AIMS Western surveillance strategies cannot be directly adapted to the Korean population. The aim of this study was to estimate the risk of metachronous neoplasia and the optimal surveillance interval in the Korean population. METHODS Clinical and pathological data from index colonoscopy performed between June 2006 and July 2008 and who had surveillance colonoscopies up to May 2015...

background: brucellosis is the most common bacterial zoonosis worldwide. greece has the highest reported incidence among eu countries. however, occupational risk factors have not been well described. objective: to determine the incidence patterns and exposure risk factors of brucellosis in greece. methods: we used national-level surveillance and occupational denominator data to estimate the inc...

OBJECTIVE To assess whether HIV surveillance data from pregnant women attending antenatal care (ANC) clinics in Zimbabwe represent infection levels in the general population. METHODS HIV prevalence estimates from ANC surveillance sites in 2006 were compared with estimates from the corresponding Zimbabwe Demographic and Health Survey 2005-06 (ZDHS) clusters using geographic information systems...

Based on the available data obtained from the population investigating, the authors reviewed research articles of the study on analytical methods and exposure levels of cadmium (Cd) in population, the injury of target organ, the evolvement of sensitive index for surveillance, the study on effects of human disease and death for environmental Cd exposure, and the study on priority surveillance of...

OBJECTIVE To estimate the long-term need for colonoscopies after a positive fecal immunochemical test (FIT) and post-polypectomy surveillance in the context of a population-based colorectal cancer (CRC) screening program. METHODS A discrete-event simulation model was built to reproduce the process of CRC screening and post-polypectomy surveillance following European guidelines in a population...

Synchronisation is an emergent phenomenon observable in nature. Natural synchronising systems have inspired the development of protocols for achieving coordination in a diverse range of distributed dynamic systems. Spontaneously synchronising systems can be mathematically modelled as coupled oscillators. In this paper we present a novel approach using model checking to reason about achieving sy...

Study objectives: Health related quality of life (HRQoL) is an important surveillance measure for monitoring the health of populations, as proposed in the American public health plan, Healthy People 2010. The authors investigated the retest reliability of four HRQoL questions from the US Behavioral Risk Factor Surveillance System (BRFSS). Design: Randomly sampled BRFSS respondents from the stat...

The aim of this work is evaluate the applicability of probabilistic model checking as an analytic tool for understanding the dynamics of ecological models. We reason that a specialist can obtain useful insights, as the results of the analyses is exact as opposed to classical deterministic models. However, in order to combat the high computational costs additional research is necessary. The form...

Health and Health Behaviors during the Worst of Times: Evidence from the Great Recession While previous studies have shown that recessions are associated with better health outcomes and behaviors, the focus of these studies has been on the relatively milder recessions of the late 20th century. In this paper, we examine if the previously established counter-cyclical pattern in health and heath b...
