INTRODUCTION Raw seafood consumption has frequently been linked to gastroenteritis and Norovirus is a common cause. In February and March 2010, there was an increase cases of gastroenteritis on the remote island of Agios Efstratios in the Northern Aegean Sea, Greece. A massive increase in seafood consumption associated with a religious festival a few days prior to the outbreak suggested seafood...

Confounding should always be addressed in studies concerned with causality. When present, it results in a biased estimate of the effect of exposure on disease. The bias can be negative—resulting in underestimation of the exposure effect—or positive, and can even reverse the apparent direction of effect. It is a concern no matter what the design of the study or what statistic is used to measure ...

BACKGROUND The issue of poor response rates to population surveys has existed for some decades, but few studies have explored methods to improve the response rate in follow-up population cohort studies. METHODS A sample of 100,000 adults from the 45 and Up Study, a large population cohort in Australia, were followed up 3.5 years after the baseline cohort was assembled. A pilot mail-out of 500...

Demographic estimates of population at risk often underpin epidemiologic research and public health surveillance efforts. In spite of their central importance to epidemiology and public-health practice, little previous attention has been paid to evaluating the magnitude of errors associated with such estimates or the sensitivity of epidemiologic statistics to these effects. In spite of the well...

background:the pattern of poisoning has a regional variability. this study was carried out to describe the epidemiological profile of acute poisoning in northeastern bangladesh and to evaluate the mortality. methods:in this retrospective cross-sectional study, medical records of poisoned patients treated at department of medicine of sylhet m.a.g. osmani medical college hospital, sylhet, banglad...

abstract: in contrast to traditional reviews, systematic reviews explore theliterature on a specific topic comprehensively using a well-defined protocol and recruit the findings of eligible studies after the assessment of their qualities, using a clear and reproducible method. checking the assumptions, we may merge the findings of recruited studies in a systematic review and use metaanalysis te...

Chronic physical and mental health conditions account for a rising proportion of morbidity, mortality, and disability in the Americas region. Household food insecurity (HFI) has been linked to chronic disease in US and Canadian women but it is uncertain if the same is true for low- and middle-income Latin American countries in epidemiologic transition. We conducted a survey to investigate the a...

We thank O. S. Ogah for his interest in our article “Cardiac Disease Patterns in Northern Malawi: Epidemiologic Transition Perspective”1. In his letter,2 Ogah agrees with us that the current epidemiologic transition in Northern Malawi is characterized by new patterns of cardiovascular diseases (CVD). Ogah, however, believes that we might have been incorrect when we stated that there was no simi...

Recent epidemiologic studies implying differences in cancer recurrence based on anesthetic regimens raise the possibility that the mu opioid receptor (MOR) can influence cancer progression. Based on our previous observations that overexpression of MOR in human non-small cell lung cancer (NSCLC) cells increased tumor growth and metastasis, this study examined whether MOR regulates growth factor ...
