AIDS-defining events among people living with HIV who have been under continuous antiretroviral therapy for more than one year, a German cohort study 1999-2018.

Purpose: This study examined the characteristics, incidence and prognostic factors of the first AIDS-defining condition developed after more than one year of continuous antiretroviral therapy (ART) among people living with HIV (PLHIV).

Methods: We used data from two multicentre observational cohorts of PLHIV in Germany between 1999 and 2018. Our outcome was the first AIDS-defining event that occurred during follow-up after more than one year of continuous ART.

AIDS in the era of antiretroviral therapy: Changes in incidence rates and predictors of AIDS among people living with HIV under clinical care in Germany, a cohort study 1999-2018.

Objectives: This study examined the incidence rates and predictive utility of established prognostic factors for the progression to AIDS among people living with HIV under clinical care.

Methods: We used data from two observational cohorts of people living with HIV in Germany between 1999 and 2018. The outcome measure was the first AIDS-defining event that occurred during follow-up.

The impact of regional socioeconomic deprivation on the timing of HIV diagnosis: a cross-sectional study in Germany.

Background: HIV infections which are diagnosed at advanced stages are associated with significantly poorer health outcomes. In Germany, the proportion of persons living with HIV who are diagnosed at later stages has remained continuously high. This study examined the impact of regional socioeconomic deprivation on the timing of HIV diagnosis.

[Quantitative profilometric surface analyses to verify the accuracy of reproduction of elastic impression material].

The optical fine scanner RM 600 Laser Stylus (Rodenstock) allows in combination with the perthometer S 8P (mechanical scanner, Feinprüf/Perthen) a direct quantitative analysis of elastic impression materials. We verified with this apparatus the accuracy of surface reproduction of thirty-three various impression materials. The mean roughness values (Rz) of the originals and the reproductions showed no significant differences.

[Reproducibility of surface roughness in vivo using elastomers, compounds and the replica technique].

A direct profilometric evaluation of impression materials, particularly elastic materials, has not been possible up to now. The optical fine scanner RM 600 Laser Stylus (Rodenstock) allows touch-free scanning of surfaces, thus providing a direct quantitative assessment of impressions made with elastic materials. To determine the suitability of various impression materials and methods for direct profilometric analyses, the accuracy of reproduction was verified by comparing the surface structures of elastomer and compound impressions as well as replicas with the original.

[Preventive dentistry--actually more than 100 years old].

The purpose of this study was to show that an intensified prevention in dentistry is not new to the 20th Century, but rather that man for more than 100 years considered the positive influence of prophylaxis on oral health to be extremely important. Three publications from Süersen (1867), Detzner (1830) and Jantzen (1865) document impressively that nothing has changed today with regard to the actuality of the questions and problems they raised. As one reviews these studies, one is astonished what profound knowledge all three authors already had regarding the etiology, origin, and consequences of caries and gingival disease.
