BACKGROUND Prehypertension is a category between normotension and hypertension that is becoming increasingly common in China. However, limited data are available on the prevalence and correlates of prehypertension in northeastern China. METHODS A cross-sectional study using stratified, clustered multistage, and random sampling methods was performed on 17,584 participants. RESULTS The preval...

A flurry of recent papers have attempted to taxonomically characterise eastern canids, mainly grey wolves Canis lupus, eastern wolves Canis lycaon or Canis lupus lycaon and northeastern coyotes or coywolves Canis latrans, Canis latrans var. or Canis latrans x C. lycaon, in northeastern North America. In this paper, we performed a meta-analysis on northeastern coyote taxonomy by comparing result...

Two waterborne outbreaks of toxoplasmosis have been described recently in southern Brazil. We present data from a community-based study of pregnant women in northeastern Brazil. Consumption of homemade ice was the only variable associated with seropositivity (adjusted odds ratio, 3.1, 95% confidence interval, 1.53-6.24). Our results suggest that water is a source of infection with Toxoplasma go...

BACKGROUND & OBJECTIVES The northeastern States of India are co-endemic for Plasmodium falciparum and P. vivax malaria. The transmission intensity is low-to-moderate resulting in intermediate to stable malaria. Malaria control prioritized P. falciparum being the predominant and life threatening infection (>70%). P. vivax malaria remained somewhat neglected. The present study provides a status r...

METHODS This observational cross-sectional survey was conducted from March 2009 to January 2010 in all level three NICUs in northeastern Brazil that are registered in the Brazilian Registry of Health Establishments (Cadastro ...

OBJECTIVES The epidemiological patterns of endemic hepatitis A virus (HAV) are unclear in northeastern Asia depending on the ethnicity of the country in question. The purpose of this study was to investigate the seroprevalence of HAV in northeastern China, South Korea, and Japan. METHODS A total of 1,500 serum samples were collected from five groups of inhabitants (300 each) who were over 40 ...

BACKGROUND Northeastern Iran has one of the highest rates of esophageal squamous cell carcinoma (ESCC) in the world. The reasons for observing such high rates of ESCC in this area are not fully clear. The current study evaluates the association between some potential risk factors and squamous dysplasia, a precursor lesion of ESCC, in northeastern Iran. MATERIALS AND METHODS Using logistic reg...

OBJECTIVES 1) To construct normal fetal biometry charts of fetal biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) from 14 to 41 weeks of gestation in northeastern Thailand. 2) To compare the results with other studies. STUDY DESIGN A cross sectional descriptive study. SETTING Division of Fetal Diagnosis and Therapy, Department of Obstet...

Temperature, nutrients, and salinity are among the important factors constraining the distribution and abundance of microorganisms in the ocean. Marine Group II (MGII) belonging to Euryarchaeota commonly dominates the planktonic archaeal community in shallow water and Marine Group I (MGI, now is called Thaumarchaeota) in deeper water in global oceans. Results of quantitative PCR (qPCR) and 454 ...

OBJECTIVE To analyze the socioeconomic inequalities in medical visits (MV) in the past year in Brazil. METHODS Data from adults aged ≥ 20 years old who participated in the Brazilian National Household Surveys and living in the Northeastern (2003; n = 75,652 and 2008, n = 79,779) and Southeastern (2003; n = 76,029 and 2008; n = 79,356) regions were analyzed according to MV. We compared MVs acc...
