Smoking is associated with the risks of mortality from breast cancer (BC) or all causes in BC survivors. Two-stage dose-response meta-analysis was conducted. A search of PubMed and Embase was performed, and a random-effect model was used to yield summary hazard ratios (HRs). Eleven prospective cohort studies were included. The summary HR per 10 cigarettes/day, 10 pack-years, 10 years increase w...
OBJECTIVE To describe changes in prevalence of child undernutrition in Northeastern Brazil in two successive time periods, identifying, in each period, the major factors responsible for these changes. METHODS Data analyzed are from probabilistic samples of underfives from three Demographic Health Surveys carried out in 1986 (n=1,302), 1996 (n=1,108), and 2006 (n=950). Identification of factor...
Occupational accidents and injuries present a serious social, medical and economical problem in Serbian industries in transition. The purpose of this study is to estimate the number and average annual rate of occupational accidents and traumatic injuries in Serbian industries in transition, between 1992 and 2003, and to estimate the effects of a preventive safety program in the rubber manufactu...
BACKGROUND The 2011 GOLD (Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Pulmonary Disease [COPD]) consensus report uses symptoms, exacerbation history, and forced expiratory volume (FEV1)% to categorise patients according to disease severity and guide treatment. We aimed to assess both the influence of symptom instrument choice on patient category assignme...
Many patients suffering from asthma or COPD have overlapping features of both diseases. However, a phenotypical approach for evaluating asthma-COPD overlap syndrome (ACOS) has not been established. In this report, we examined the phenotypes in patients with ACOS. Patients diagnosed with ACOS between 2011 and 2015 were identified and classified into four phenotype groups. Group A was composed of...
Background: Chronic obstructive pulmonary disease (COPD) is a largely underdiagnosed disease including several phenotypes. In this report, the design of a study intending to evaluate the pathophysiological mechanism in COPD in relation to the specific phenotypes non-rapid and rapid decline in lung function is described together with the recruitment process of the study population derived from a...
Each symmetric matrix A over C defines a graph homomorphism function ZA(·) on undirected graphs. The function ZA(·) is also called the partition function from statistical physics, and can encode many interesting graph properties, including counting vertex covers and k-colorings. We study the computational complexity of ZA(·) for arbitrary symmetric matrices A with algebraic complex values. Buil...
