Mortality associated with HIV-1, HIV-2, and HTLV-I single and dual infections in a middle-aged and older population in Guinea-Bissau.

Background: In Guinea-Bissau HIV-1, HIV-2, and HTLV-I are prevalent in the general population. The natural history of HIV/HTLV-I single and dual infections has not been fully elucidated in this population. Previous studies have shown that combinations of these infections are more common in older women than in men.

Short and long term mortality associated with foodborne bacterial gastrointestinal infections: registry based study.

Objectives: To determine the excess mortality associated with infections with Salmonella, Campylobacter, Yersinia enterocolitica, and Shigella and to examine the effect of pre-existing illness.

Design: Registry based, matched cohort study.

Setting: Denmark.

[Excess mortality associated with antibiotic resistant Salmonella typhimurium].

Introduction: The use of antimicrobials in food production has been associated with drug-resistance in foodborne pathogens such as Salmonella and Campylobacter. However, little is known about the health impact of antimicrobial drug-resistance in these pathogens. In a matched cohort study, we determined the mortality associated with drug-resistance in Salmonella Typhimurium.

Dual infections with HIV-1, HIV-2 and HTLV-I are more common in older women than in men in Guinea-Bissau.

Objectives: To investigate the association between the three human retroviruses, HIV-1, HIV-2 and HTLV-I.

Design: Community-based follow-up studies of retrovirus infections in two cohorts.

Methods: A total of 2057 individuals aged 35 years and over were eligible for inclusion.

Fever in pregnancy and risk of fetal death: a cohort study.

Background: Hyperthermia acts as a teratogen in some animals where it can induce resorption of the fetus and fetal death. Fever during pregnancy, especially in the period of embryogenesis, is also suspected as being a risk factor for fetal death in human beings. We did a large cohort study in Denmark to investigate this possibility.

Increased prevalence of HTLV-1 among HIV-2-infected women but not HIV-2-infected men in rural Guinea-Bissau.

Objective: To assess the prevalence of HTLV infection and its association with HIV and other potential risk factors.

Design And Setting: A cross-sectional survey and a case-control study in a rural community in Guinea-Bissau.

Methods: A total of 2770 people were included in an HIV and HTLV seroepidemiologic survey.

Excess mortality associated with antimicrobial drug-resistant Salmonella typhimurium.

In a matched cohort study, we determined the death rates associated with drug resistance in Salmonella Typhimurium. We linked data from the Danish Surveillance Registry for Enteric Pathogens with the Civil Registration System and the Danish National Discharge Registry. By survival analysis, the 2-year death rates were compared with a matched sample of the general Danish population, after the data were adjusted for differences in comorbidity.
